The terminology used in this specification for the purpose of describing specific embodiments is not intended to limit the disclosure.

    [0050] The following will describe some embodiments of the present disclosure in conjunction with the accompanying drawings. In cases where there is no conflict, the following embodiments and features within the embodiments may be combined with each other. Moreover, the dashed lines depicted in the drawings of this disclosure do not represent a physical structure but are merely for distinguishing different features.

    [0051] Referring to FIGS. 1 and 2, one embodiment of the disclosure provides a box cover 10, which is used to seal a box body 20 with a first opening 32. An inner surface of the box cover 10 is provided with a protruding component 11, and the box body 20 has a connecting component 21. The protruding component 11 is abutted against and connected to a connecting component 21 of the box body 20 by means of interface fusion, to form an integrated connection. It can be understood that, compared to traditional connection methods such as snap-fit, adhesive bonding, threaded connections, bolted connections, or latch connections, the box cover 10 of the present embodiment forms an integrated structure through the interface fusion of protruding component 11 and the connecting component 21 of box body 20, which is beneficial for enhancing the stability and reliability of the connection between the box cover 10 and the box body 20, thereby reducing the risk of internal components of the box body 20 leaking or coming out.

    [0052] It can be understood that the interface fusion in this disclosure refers to applying energy (such as heat, pressure, friction, etc.) at the contact interface of the two components to partially melt the material of the contact surface. When the melted material mixes and subsequently cools and solidifies, it forms a shared, continuous integral structure or a tightly bonded transition layer, thus firmly connecting the two parts into one.

    [0053] In another embodiment, as shown in FIG. 2, the protruding component 11 includes at least one first protruding portion 111 that abuts against the connecting component 21 of box body 20 and undergoes interface fusion. It can be understood that a number of first protruding portions 111 may be one, two, or more.

    [0054] In another embodiment, as shown in FIGS. 2 and 3, the first protruding portion 111 has a first surface 11a, and the first surface 11a is abutted against and connected to the first end face 21a of connecting component 21 through interface fusion.

    [0055] In another embodiment, the first protruding portion 111 is a strip-shaped body, and an arrangement of the strip-shaped body is beneficial for further increasing the area of interface fusion between first protruding portion 111 and the connecting component 21 of box body 20, which is advantageous for enhancing the stability and reliability of the connection between the box body 20 and the box cover 10.

    [0056] In another embodiment, the first protruding portion 111 is a dot-shaped body, which helps reduce the material and overall weight of the box cover 10.

    [0057] In some embodiments, the first protruding portion 111 is continuously distributed along a predetermined direction, such that the protruding component 11 is composed of one or more continuous segments.

    [0058] In some embodiments, the first protruding portion 111 is spaced apart along a predetermined direction, such that the protruding component 11 is composed of one or more non-continuous segments.

    [0059] In some embodiments, referring to FIGS. 2 and 3, the protruding component 11 includes at least one first protruding portion 111, which is a strip-like body. The first protruding portion 111 has a first surface 11a, where the first surface 11a is abutted against and fused to the first end face 21a of the connecting component 21 through interface fusion.

    [0060] In some embodiments, referring to FIG. 4, the protruding component 11 includes at least one first protruding portion 111, which is a strip-like body. The first protruding portion 111 also has a first inner side surface 11b, which is abutted against and fused to the first inner side end face 21b of the connecting component 21 through interface fusion.

    [0061] In some embodiments, referring to FIG. 4, the protruding component 11 includes at least one first protruding portion 111, which is a strip-like body. The first protruding portion 111 has a first surface 11a and a first inner side end face 21b, where the first surface 11a is abutted against and fused to the first end face 21a of the connecting component 21 through interface fusion, and the first inner side surface 11b is abutted against and fused to the first inner side end face 21b of the connecting component 21 through interface fusion.

    [0062] It should be understood that the first surface 11a and the first inner side end face 21b are surfaces at different positions of the first protruding portion 111. For example, the first surface 11a is the surface on one side of the box cover 10 facing towards the box body 20, and the first inner side end face 21b is the surface that forms an angle with the first surface 11a, such as being perpendicular to it. When both the first surface 11a and the first inner side end face 21b are abutted against and fused to the connecting component 21 of the box body 20 through interface fusion, it is advantageous to enhance the area of connection between the first protruding portion 111 and the connecting component 21, allowing for connections to be secured simultaneously at different angles and positions, thereby further enhancing the stability and reliability of the connection between the box cover 10 and the box body 20.

    [0063] In some embodiments, referring to FIG. 5, the first protruding portion 111 also includes a first outer side surface 11c, which is abutted against and fused to the first outer side end face 21c of the connecting component 21 through interface fusion.

    [0064] As an example, the first outer side surface 11c is arranged opposite to the first inner side surface 11b, meaning that they are the surfaces on opposite sides of the first protruding portion 111. When the first inner side surface 11b, the first outer side surface 11c, and the first end face 21a of the first protruding portion 111 are abutted against and fused to the connecting component 21 of the box body 20 through interface fusion, it is advantageous to enhance the area of connection between the first protruding portion 111 and the connecting component 21, allowing for connections to be secured simultaneously at different angles and positions, thereby further enhancing the stability and reliability of the connection between the box cover 10 and the box body 20.

    [0065] In some embodiments, referring to FIG. 5, the box cover 10 has a second surface 12, which is abutted against and fused to the second end face 21e of the connecting component 21 through interface fusion. It should be understood that the second surface 12 and the first surface 11a are surfaces at different positions on the box cover 10, for instance, the second surface 12 is not a surface of the first protruding portion 111.

    [0066] As an example, the first surface 11a is parallel to the second surface 12, and the first end face 21a is parallel to the second end face 21e.

    [0067] In some embodiments, referring to FIG. 6, the protruding component 11 includes at least one first protruding portion 111, which is a dot-shaped body. The first protruding portion 111 includes a first surface 11a, where the first surface 11a is abutted against and fused to the first end face 21a of the connecting component 21 through interface fusion.

    [0068] In some embodiments, referring to FIG. 6, the protruding component 11 includes at least one first protruding portion 111, which is a dot-shaped body. The first protruding portion 111 includes a first circumferential side surface 11d, where the first circumferential side surface 11d is abutted against and fused to the first side end face 21d of the connecting component 21 through interface fusion.

    [0069] In some embodiments, the protruding component 11 includes at least one first protruding portion 111, which is a dot-shaped body. The first protruding portion 111 includes a first surface 11a and a first circumferential side surface 11d, where the first surface 11a is abutted against and fused to the first end face 21a of the connecting component 21 through interface fusion, and the first circumferential side surface 11d is abutted against and fused to the first side end face 21d of the connecting component 21 through interface fusion.

    [0070] It is understandable that the first surface 11a and the first circumferential side surface 11d of the first protruding portion 111 are surfaces at different positions of the first protruding portion 111. For example, the first surface 11a is the surface on one side of the box cover 10 facing the box body 20, and the first circumferential side surface 11d is the surface at an angle to the first surface 11a, for instance, the first circumferential side surface 11d is perpendicular to the first surface 11a. When both the first surface 11a and the first circumferential side surface 11d are connected to the connecting component 21 of the box body 20 by abutting against it and interface fusion, it helps to enhance the connection area between the first protruding portion 111 and the connecting component 21, and allows for simultaneous connection and fixation at different angles and positions, thus further improving the stability and reliability of the connection between the box cover 10 and the box body 20.

    [0071] In some embodiments, as shown in FIG. 7, the box cover 10 has at least one cylindrical body 13, which is used for engaging with the snapping column 22 of the connecting component 21. The engagement between the cylindrical body 13 and the snapping column 22 enhances the stability of the connection between the box cover 10 and the box body 20. Furthermore, through the engagement between the cylindrical body 13 and the snapping column 22, a pre-connection can be established between the box cover 10 and the box body 20, aligning the protruding component 11 of the box cover 10 with the corresponding part of the connecting component 21 of the box body 20. This alignment facilitates the interface merging process between the protruding component 11 and the connecting component 21, improving the precision of the connection and enhancing the consistency of the product quality.

    [0072] In some embodiments, as shown in FIG. 7, a number of the cylindrical body 13 is two or more, which further enhances the stability of the connection between the box cover 10 and the box body 20, making it easier for the protruding component 11 of the box cover 10 to align with the corresponding part of the connecting component 21 of the box body 20.

    [0073] In some embodiments, as shown in FIG. 7, the protruding component 11 also includes a second protruding portion 14, which is an annular body arranged around the outer periphery of the cylindrical body 13, and the annular body has a third surface 141. The third surface 141 abuts against and connects to the first end face 221 of the snapping column 22 through interface fusion. This arrangement provides the cylindrical body 13 with a circumferential structure that is integrally formed by interface fusion, further enhancing the stability and reliability of the connection between the box cover 10 and the box body 20, while reducing the possibility of the box cover 10 detaching from the box body.

    [0074] In some embodiments, as shown in FIG. 7, a plurality of first protruding portions 111 and a plurality of second protruding portions 14 are provided. The plurality of first protruding portions 111 and the plurality of second protruding portions 14 are arranged alternately along an edge of the box cover 10. This configuration increases the area of interface fusion between the box cover 10 and the box body 20 and expands the distribution range of the interface merging, thus further enhancing the stability and reliability of the connection between the box cover 10 and the box body 20 and reducing the likelihood of the box cover 10 detaching from the box body.

    [0075] In some embodiments, as shown in FIG. 7, there are four first protruding portions 111, located at the four corners of the box cover 10, while the second protruding portions 14 are positioned between adjacent first protruding portions 111. This arrangement increases the area of interface fusion between the box cover 10 and the box body 20 and helps to achieve a more uniform and comprehensive distribution of the integrally formed structure at the interface, further enhancing the stability and reliability of the connection between the box cover 10 and the box body 20 and reducing the likelihood of detachment.

    [0076] In some embodiments, as shown in FIG. 7, the box cover 10 also includes reinforcing ribs 15 extending radially outward from a center. The reinforcing ribs 15 enhance the structural strength of the box cover 10 and help reduce the chances of damage or cracking when the box cover 10 is subjected to impacts, etc.

    [0077] In some embodiments, the center of the box cover 10 is equipped with a reinforcing protrusion 16. One end of each of the reinforcing rib 15 connects to the first protruding portion 111, while the other end connects to the reinforcing protrusion 16. This arrangement not only reinforces the overall structure of the box cover 10 but also reinforces the first protruding portion 111 structurally.

    [0078] In some embodiments, as shown in FIG. 7, there are a plurality of first protruding portions 111, and the protruding component 11 also includes a third protruding portion 17, which connects two adjacent first protruding portions 111. The center of the box cover 10 is again equipped with a reinforcing protrusion 16, with one end of the reinforcing rib 15 connecting to the third protruding portion 17 and the other end connecting to the reinforcing protrusion 16. This arrangement further enhances the overall strength of the box cover 10 and improves the structural strength of the third protruding portion 17.

    [0079] In some embodiments, the third protruding portion 17 and the box cover 10 are integrally formed by interface fusion, which enhances the stability and reliability of the connection between the box cover 10 and the box body 20.

    [0080] In some embodiments, the box cover 10 has a roughly polygonal shape, with a third protruding portion 17 set along each side. This design further enhances the stability of the connection between the box cover 10 and the box body 20.

    [0081] In some embodiments, as shown in FIG. 7, there are multiple third protruding portions 17, which are strip-shaped. These multiple third protruding portions 17 are sequentially connected end to end, forming a boundary around the plurality first protruding portions 111 and the plurality second protruding portions 14. The third protruding portions 17 are integrally formed with the box cover 10 through interface fusion. This setup further strengthens the box cover 10 and enhances the stability and reliability of its connection to the box body 20.

    [0082] In other embodiments, as shown in FIGS. 9 and 10, the protruding component 11 also includes at least one third protruding portion 17, which is positioned close to the edge of the box cover 10. The third protruding portion 17 is strip-shaped and has a fourth surface 171, which abuts against and merges with the third end face 21f of the connecting component 21.

    [0083] Continuing to refer to FIGS. 9 and 10, in some embodiments where the fourth surface 171 abuts and is connected to the third end face 21f of the connecting component 21 through interface fusion, there are a plurality of first protruding portions 111 and a plurality of third protruding portions 17, with each third protruding portion 17 being located between any two adjacent first protruding portions 111, and the third protruding portion 17 being spaced from the first protruding portion 111.

    [0084] Continuing to refer to FIGS. 9 and 10, in some embodiments, the fourth surface 171 is abutted against and connected to the third end face 21f of the connecting component 21 through interface fusion, the box cover 10 is a rectangular cover, with four third protruding portions 17, one on each edge of the box cover 10, and the extending rectangle of the protruding portion 17 is parallel to the edge extension direction of the corresponding side.

    [0085] It is understood that the thickness of the box cover 10, the thickness of the first protruding portion 111, and the thickness of the third protruding portion 171 are not limited here. For example, if the dimensions of the box cover 10 are 2 cm in length, 2 cm in width, and 2 mm in thickness, the thickness of the first protruding portion 111 can be 0.5 mm, 0.6 mm, 0.7 mm, 0.8 mm, 0.9 mm, 1 mm, or other thicknesses, while the thickness of the third protruding portion can be 0.5 mm, 0.6 mm, 0.7 mm, 0.8 mm, 0.9 mm, 1 mm, or other thicknesses.

    [0086] In some embodiments, the outer surface of the box cover 10 is flush with the end face of the box body 20 with an opening, which helps to reduce the forces experienced at the joint between the box cover 10 and the box body 20, further enhancing the stability of the connection between the box cover 10 and the box body 20.

    [0087] In some embodiments, referring to FIG. 11, the combination block 100 includes the box body 20 and the box cover 10 of any of the aforementioned embodiments, where the box body 20 includes an outer side wall 30 and a connecting component 21, with the outer side wall 30 enclosing to form a installation chamber 31 and a first opening 32, where the first opening 32 communicates with the installation chamber 31. The connecting component 21 is provided inside the installation chamber 31, abutting against the protruding component 11 at least partially and connected through interface fusion.

    [0088] In some embodiments, the first opening 32 is along the outer side wall 30 of the box body 20. Observing along the thickness direction of the box cover 10, the outer side wall 30 can be in a regular shape such as triangular, rectangular, pentagonal, hexagonal, etc., or in other irregular shapes, and is not specifically limited here. For ease of understanding, this disclosure describes the outer side wall 30 as rectangular along the thickness direction of the box cover 10 as an example to illustrate other structures.

    [0089] In some embodiments, referring to FIG. 11, the connecting component 21 includes an abutment seat 211 that connects to the outer side wall 30. The abutment seat 211 has a first end face 21a that is fitted against the first surface 11a and has a shape that matches the first surface 11a, which facilitates the accuracy and integrity of the interface fusion between the first protruding portion 111 and the abutment seat 211.

    [0090] In some embodiments, a number of abutment seats 211 is consistent and one-to-one corresponding with a number of first protruding portions 111.

    [0091] In some embodiments, the abutment seat 211 is fixedly connected to the outer side wall 30.

    [0092] In some embodiments, the connecting component 21 also includes a snapping column 22 connected to the outer side wall 30, which has a second opening 222 for accommodating the cylindrical body 13. This allows for the snapping connection between the cylindrical body 13 and the snapping column 22, which helps improve the stability of the connection between the box cover 10 and the box body 20.
