DETAILED DESCRIPTION

[0014] FIG. 1 shows a preferred implementation of an electronic device according to the present invention. The electronic device includes a housing 1 and a sealing cover 2. Electronic components of the electronic device are provided in the housing 1, and the sealing cover 2 can close the housing 1, so that the electronic components are in a closed environment. The sealing cover 2 is detachable, so that the electronic device can be assembled, disassembled and maintained conveniently.

[0015] As shown in FIG. 1, the housing 1 is provided with a first fitting member 1a, and a protruding structure 4 is provided on both sides of the first fitting member 1a. The sealing cover 2 is provided with a second fitting member 2a and a third fitting member 2b, and an engagement structure 3 is provided at corresponding positions of the second fitting member 2a and the third fitting member 2b respectively. An engagement opening 5 is provided at a corresponding position of the engagement structure 3 for mating connection with the protruding structure 4. When the sealing cover 2 is connected to the housing 1, the protruding structures 4 extend into the engagement openings 5 to achieve snap-fit connection between the sealing cover 2 and the housing 1. In a locked state, the first fitting member 1a can be connected to the second fitting member 2a and the third fitting member 2b by way of snap-fit connection; and in an unlocked state, the first fitting member 1a can be connected to only the second fitting member 2a or only the third fitting member 2b by way of snap-fit connection, or alternatively, the first fitting member 1a is not connected to either of the second fitting member and the third fitting member, thereby achieving a more flexible removal mode of the sealing cover.

[0016] In this embodiment, a guide groove 8 is provided at a corresponding position of the first fitting member 1a of the housing 1, so that the engagement structure 3 can be connected to the protruding structure 4 precisely in a particular direction by way of snap-fit connection. A bending portion 6 bent upwards is provided at the front end of the engagement structure 3, and the bending portion 6 mainly has two functions: one is to allow the engagement structure 3 to move across the protruding structure 4 more easily so as to enable the protruding structure 4 to be inserted into the engagement opening 5 when the engagement structure 3 is guided to the protruding structure 4, and the other one is to allow the engagement structure 3 to be manually pulled away from the protruding structure 4 more easily when the engagement structure 3 is to be separated from the protruding structure 4. Correspondingly, a guide bevel may also be provided on one side of the protruding structure 4 facing the engagement structure 3 to facilitate the fitting of the engagement structure 3 and the protruding structure 4. In this embodiment, only one protruding structure 4 is provided on each of two sides of the housing 1, and a corresponding engagement structure 3 is provided on each of two sides of the sealing cover 2. Further preferably, a plurality of paired engagement structures 3 and protruding structures 4 may also be provided according to the shape of the housing and actual needs, and for example, the engagement structures 3 and the protruding structures 4 are respectively provided at four corners of the sealing cover 2 and corresponding positions of the housing 1, thereby making the connection between the sealing cover 2 and the housing 1 firmer.

[0017] After the sealing cover 2 and the housing 1 have been assembled, there is a gap 12 between the sealing cover 2 and the housing 1 due to manufacturing tolerance, as shown in FIG. 3. In order to meet EMI protection requirements, it is necessary to minimize the size and length of the gap. In this embodiment, a folding line 7 is provided in the middle of the sealing cover 2. As shown in FIG. 3, the folding line 7 enables the sealing cover 2 to be in the form of a fold line in a top view, thereby reducing the size and length of the gap between the sealing cover 2 and the housing 1.

[0018] FIG. 2 shows a perspective view of the sealing cover 2 and the housing 1 in a locked state. As shown in the figure, the protruding structure 4 is inserted into the engagement opening 5 to achieve snap-fit connection between the housing 1 and the sealing cover 2. A guide rail 10 is provided on a path of the sealing cover 2 moving toward the housing 1, so that the sealing cover 2 is precisely connected to the housing 1 along the guide rail 10, and especially in the case of automated assembly, the guide rail 10 can guide the sealing cover 2 to move to the housing 1 automatically. In the locked state, elastic force away from the first fitting member 1a as shown by the arrow direction in FIG. 2 is present in the second fitting member 2a and the third fitting member 2b of the sealing cover 2, so that the second fitting member 2a and the third fitting member 2b more tightly abut the first fitting member 1a, or alternatively, the second fitting member 2a and the third fitting member 2b are closer to the first fitting member 1a, thereby reducing the size and length of the gap between the sealing cover 2 and the housing 1.

[0019] According to the above-mentioned design solution of the present invention, the sealing cover may be connected to the housing by the following steps: [0020] Step 1. moving the sealing cover 2 along the guide rail 10 until the folding line 7 is in contact with the housing 1; [0021] Step 2. providing holding force for securing the sealing cover 2 to the housing 1 by the curved feature of the sealing cover 2; and [0022] Step 3. continuing to push the sealing cover 2 towards the housing 1 until the protruding structure 4 is inserted into the engagement opening 5 of the engagement structure 3.

[0023] It should be understood that although the foregoing descriptions and drawings illustratively describe some embodiments of the present invention, they are merely used as an example and not intended to limit the scope of protection of the present invention in any way. Various variations of the embodiments are also possible without departing from the scope of the claims and the scope associated therewith, particularly variations that are not mentioned in the claims and derived from the description of the embodiments and the accompanying drawings as well as the features. These features may also occur in a manner other than combinations specifically disclosed herein. A plurality of features of the present invention are mutually involved in the same sentences or in another context, but this does not prove that these features can only be present in particularly disclosed combinations; instead, single features may also be removed or replaced from the plurality of such features provided that the functionality of the present invention is not affected.
