FIG. 2 displays a perspective view of the main unit module according to another embodiment of the present invention. FIG. 3 provides a partial cross-sectional view of the pedal as shown in FIG. 2. To achieve at least one of the aforementioned advantages or other benefits, an embodiment of the present invention provides a main unit module 1 capable of being combined with various caring modules to offer diverse care functions and perform actions such as shifting and moving.

[0065] As depicted in FIGS. 1 and 3, the main unit module 1 comprises a shifting module 100, a supporting frame module 200, and a coupling module 10. The shifting module 100 includes at least a chassis unit 110 and a wheel caster set 120. The chassis unit 110 is positioned horizontally, the wheel caster sets 120 are pivotally connected to both sides of the chassis unit 110. The wheel caster sets 120 can open and close, driving the main unit module 1 to move. The chassis unit 110 is equipped with a flat upper surface 112 that can function as a pedal. In FIG. 3, the chassis unit 110 consists of a chassis body 150 and a moving pedal 170. The chassis body 150, forming a U-shaped structure, is used to accommodate the wheel caster set 120 the supporting frame module 200 while guiding the movement of the moving pedal 170. The moving pedal 170 comprises a T-shaped sliding body 160 and a pedal 171. The T-shaped sliding body 160 is composed of a straight bar 161 and a crossbar 162 perpendicular to each other. In this embodiment, the upper surface of the pedal 171 corresponds to the flat upper surface 112 of the chassis unit 110, but the present invention is not limited to this configuration. In the embodiment shown in FIG. 3, one end of the straight bar 161 is securely fitted into the groove in the center of the crossbar 162, forming a T-shaped structure that matches the chassis body 150. Together, they define the bottom frame of the chassis unit 110, which accommodates the pedal 171. The U-shaped structure of the chassis body 150 provides guide units 151/152 in the center and on both sides, respectively. The guide unit 151 in the center of the U-shaped structure is designed to slidably receive the straight bar 161 of the T-shaped sliding body 160. The guide units 152 are intended to slidably receive both ends of the crossbar 162. The pedal 171 is positioned above the T-shaped sliding body 160, so that the pedal 171 can slide forward and backward on the guide unit 151/152 of the chassis body 150, moving between different positions. The guide unit 151 is equipped with a locking member 154, securing the straight rod 161 to fix the moving pedal 170 in various positions. The pedal 171 can meet multiple demands, such as acting as a pedal for the user to rest their feet or as a mounting surface for attaching and installing other modules and components. The form of the guide unit 151/152 may vary and is not restricted to a groove or rod shape, as long as it facilitates smooth sliding when coupled with the moving pedal. In one embodiment, the pedal 171 of the chassis unit 110 may comprise stripes to increase friction, enhancing its anti-slip properties. On both sides of the chassis body 150, there are two mounting locking plates 113. These two mounting locking plates 113 have a receiving surface 114 aligned with the flat upper surface 112 of the chassis unit 110, allowing them to mount and carry other components.

[0066] The wheel caster set 120 comprises at least multiple universal wheel caster sets 122, at least one directional wheel caster set 124, two long legs 121, and two short legs 123. The universal wheel caster sets 122 have unrestricted movement direction on the horizontal plane when rotating. In the depicted embodiment, the wheel caster set 120 consists of four universal wheel caster sets 122. The wheel caster sets are pivotally mounted on both sides of the chassis unit 110 through two long legs 121, two short legs 123, and pivot shafts 125. The long legs 121 and short legs 123 are positioned beneath the chassis unit 110 through the mounting locking plates 113 the pivot shaft 125. That is, each side end of the chassis unit 110 is equipped with one long leg 121, one short leg 123, and two universal wheel sets 122. A universal wheel caster set 122 is attached to one end of each long leg 121 and each short leg 123, while the other end is fixed beneath the chassis unit 110. Two long legs 121 and two short legs 123 are positioned on the front and rear sides of the chassis unit 110. Please note that the diameter of the universal wheel caster set 122 installed on the short leg 123 is larger than the diameter of the universal wheel caster set 122 installed on the long leg 121. Control devices are provided on both the long leg 121 the short leg 123 to control the positioning and locking of the universal wheel caster sets 122. The two long legs 121 of the caster set 120 can swing open and close, facilitating compatibility with assistive devices such as wheelchairs. Opening the two long legs 121 enhances the overall stability of the main unit module 1.

[0067] In order to enhance controllability and safety during shifting, the directional wheel caster set 124 is designed to only move in a predefined direction on the horizontal plane when it rotates. The directional wheel caster set 124 is positioned near the middle of the front side of the chassis unit 110 and enclosed within a horizontal area formed by the vertices of the universal wheel caster sets, and includes a directional wheel 127, an elastic device 128, and a switching device 126. The directional wheel 127 is movably installed beneath the directional wheel caster set 124 through the elastic device 128, allowing the axis position of the directional wheel 127 to be adjusted vertically. The directional wheel caster set 124 ensures continuous ground contact of the directional wheel 127 through the action of the elastic device 128, maintaining its effectiveness throughout the movement. The switching device 126 is positioned near the directional wheel 127, the switching device 126 is used to controls the directional wheel's orientation, enabling it to be fixed in a predefined direction or left in a freely rotatable state. In other words, activation of the switching device 126 stabilizes the forward direction of the directional wheel 127, directing the shifting module 100 to move in the predefined direction. Conversely, deactivating the switching device 126 allows the directional wheel 127 to rotate freely, similar to a universal wheel, permitting movement in any direction. The switching between directional and non-directional states can be achieved through any suitable directional mechanism. For instance, the switching device 126 the directional wheel 127 may comprise positioning pins and corresponding positioning holes (not shown in the figure). By coupling or decoupling the two switching operations, the directional wheel 127 can be in a directional or non-directional state, thereby meet the shifting operation requirements of different applications. The directional wheel 127 can provide multiple directional positions, enabling the switching device 126 to alter its positioning direction. This configuration of the wheel caster set 120 enhances the stability and ease of movement for the shifting module 100 the main unit module 1, providing more convenient control. Additionally, the directional wheel caster set 124 the moving pedal 170 have the capability to move relative to the long leg 121 toward the short leg 123.

[0068] The supporting frame module 200 comprises multiple upright poles 210 and multiple connecting plates 220. One end of the upright poles 210 is attached and secured to the chassis unit 110 of the shifting module 100, while the other end is connected and fixed below the multiple connecting plates 220. In other words, the multiple connecting plates 220 are positioned above the chassis unit 110, the upright poles 210 span between the chassis unit 110 the multiple connecting plates 220. As illustrated, one end of the upright poles 210 is mounted and fixed on the receiving surface 114 of the mounting locking plates 113 of the chassis unit 110. This configuration allows the moving pedal 170 of the chassis unit 110 to move towards the short leg 123 relative to the long leg 121 without hindrance.

[0069] A plurality of first keyholes 212 are arranged along the vertical direction on the upright pole 210, forming a coupling interface designed to install and lock caring modules with different functions. The number and spacing of these holes can be adjusted on the four upright poles 210 according to specific requirements. The first keyhole 212 creates four independent coupling interfaces that can collaborate with each other. The installation height of caring modules with different functions can be customized by utilizing the first keyholes 212 located at various heights on the four upright poles 210. On the horizontal surface of the connecting plate 220, there are multiple first mounting holes 222 (forming a coupling interface), and on the vertical surface, there are multiple second keyholes 224. These can be utilized in conjunction with multiple fasteners 226 to establish another coupling module device and secure the components installed in the first mounting hole 222. One end of the upright pole 210 is affixed to the first mounting holes 222 and secured beneath the connecting plate 220 using the second keyholes 224 and fasteners 226. The arrangement of the first keyholes 212, the first mounting holes 222, the second keyholes 224 may be at equal intervals, but are not limited to. It can be understood that the multiple upright poles 210 are employed to fix the multiple connecting plates 220 above the chassis unit 110, enabling the main unit module 1 to install care modules or other components with various functions through the multiple upright poles 210 and connecting plates 220.

[0070] To provide further clarification, in a specific embodiment, the connecting plates 220 are horizontally installed and perpendicular to the upright poles 210. The upright pole 210 may be a hollow cylindrical tube and made of metal material, while the connecting plate 220 is generally elongated with a certain thickness to facilitate the arrangement of through holes. The multiple first mounting holes 222 on the connecting plate 220 are positioned vertically and are designed as through holes. The multiple second keyholes 224 the multiple fasteners 226 on the connecting plate 220 are arranged horizontally and perpendicular to the multiple first mounting holes 222.

[0071] The coupling module 10 comprises multiple coupling devices 12 and coupling interfaces that are disposed on the supporting frame module 200 and can be used independently or in conjunction with the supporting frame module 200 to attach and secure caring modules with various functions. The coupling device 12 is slidably encased on the and secured to upright pole 210 through the first keyholes 212. Different caring modules with diverse functions can be mounted and secured on the pole 210 using the first keyholes 212 the coupling devices 12. Different caring modules are positioned on one side of the supporting frame module 200, enabling convenient and rapid adjustment of care at different heights. Additionally, besides the first keyhole, the first mounting hole on the connecting plate, the second mounting hole on the chassis unit can also serve as coupling interfaces for attaching the care module. That is, the coupling interface of the coupling module 10 may include, but is not restricted to, the first keyholes 212, the first mounting holes 222, the second mounting holes 115. In certain applications, the caring module can be directly combined with the corresponding coupling interface and installed on the main unit module 1 without the need for a coupling device.

[0096] Please refer to FIGS. 10 to 12 in conjunction with FIGS. 1 and 4. FIG. 10 is a perspective view of another embodiment of the caring machine of the present invention. FIG. 11 is a perspective view of an embodiment of the large wheel module of the caring machine shown in FIG. 10. FIG. 12 is a perspective view of the large wheel module shown in FIG. 11 during operation.

[0097] Please refer to FIG. 10 in conjunction with FIGS. 1 and 4. To further enhance the versatility and functionality of the aforementioned caring machine 2, additional features can be incorporated to serve multiple purposes. Specifically, the caring machine 2 can be provided with a large wheel module 600 mounted on the main unit module 1. The large wheel module 600 comprises at least two mounting brackets 610, a first crossbar 620, two braking mechanisms 630, and two large wheels 640. The two mounting brackets 610 are symmetrically positioned on the upright pole 210, which supports the frame module 200 the wheel caster set 120 of the shifting module 100. Each mounting bracket 610 is installed on the long leg 121 of the wheel caster set 120. The two ends of the first crossbar 620 are connected and securely fixed to the two mounting brackets 610, thereby reinforcing the stability of the connection between the mounting brackets 610. The two braking mechanisms 630 are individually fitted onto the rotating rods 615 of the large wheels 640 and are synchronized with the movement of the large wheels 640. The two large wheels 640 are affixed and secured through the rotating rods 615 that are respectively installed on the large wheel rotating hole devices 616 of the mounting brackets 610, and two large wheels 640 are positioned outside the mounting brackets 610.

The lifting device 650 enables adjustment of the height of the wheel caster set 120 connected to the mounting bracket 610 by controlling its operation. That is, manipulation of the lifting device 650 allows for the height adjustment of the long leg 121 in the wheel caster set 120, thereby raising the universal wheel caster set 122 on the long leg 121 to a certain distance from the ground so as to facilitate the installation of the large wheel 640 to the mounting bracket 610. Subsequently, the large wheel 640 is mounted onto the mounting bracket 610, serving as a replacement for the wheel on the long leg 121 in the wheel caster set 120. Each lifting device 650 comprises at least an elevated frame 651 and a set of limiting pins 652, and is used to elevate the wheel caster set 120 and simplify the process of installing or removing the large wheel 640 onto/from the mounting bracket 610. In a word, the two elevated frames are lowered to make contact with the ground and are restricted by the limiting pins 652 from rotating upward. Subsequently, force is applied in the direction of the front wheels using the push module 3. As a result, the universal wheel caster set 122 of the long leg 121 is lifted to a certain distance from the ground using the point where the elevated frames 651 touch the ground as a fulcrum. At this point, the elevated frame 651 surpasses the highest point and is secured in a stable stationary state by another limiting pin 652. It facilitates the convenient installation or disassembly of the large wheel 640 onto/from the mounting bracket 610.

[0099] Once the large wheel 640 is installed, it serves as the wheel for the long leg 121 of the wheel caster set 120. Consequently, the large wheel module 600 in conjunction with the short leg 123 of the wheel caster set 120 from the shifting module 100 is used to be as a wheel in the caring machine 2. It allows the caring machine 2 to function as a wheelchair outdoors, facilitating users in engaging in basic life activities outdoors.

[0100] To elaborate further, each mounting bracket 610 of the large wheel module 600 comprises at least an upper locking device 611 and a lower locking device 612. The upper locking device 611 facilitates connection and locking with the upright pole 210 of the supporting frame module 200, while the lower locking device 612 is utilized for connection and locking with the long leg 121 of the wheel caster set 120 from the shifting module 100. The lifting device 650 can be installed on the lower locking device 612 under the mounting bracket 610. Thus, it's possible for straightforward and swift assembly and disassembly of the large wheel module 600.
