[0030] See Figures 1-3As shown, this application proposes a modular service vehicle 100. The modular service vehicle 100 includes a main body 10, a connector 20, and a secondary body 30. The main body 10 includes a body frame 11, a storage plate 12 mounted on the body frame 11, and wheels 13 mounted at the four corners of the body frame 11. The body frame 11 has a rectangular three-dimensional design, and the top edge of the body frame 11 has a first mounting groove 111 on its periphery. The connector 20 includes a mounting plate 21 and a support plate 23. The mounting plate 21 is vertically arranged, and its upper end is bent to one side to form a first hook 211 adapted to the first mounting groove 111. The connector 20 is connected via the first hook. The engagement between 211 and the first hook 111 is detachably connected to the main body 10. The support plate 23 is horizontally arranged on the side opposite to the hook 21 and the first hook 211. The sub-body 30 includes an extension platform 31 and a support leg 32 with a traveling wheel 13. One end of the extension platform 31 is attached to the support plate 23. The support leg 32 is located at the end of the extension platform 31 away from the main body 10, and is used to support the extension platform 31 together with the main body 10, so that the extension platform 31 and the top of the main body 10 are at the same level.

[0031] In this application's technical solution, the first mounting slot 111 is formed on the periphery of the top edge of the vehicle frame 11, providing a mounting point for the connector 20, enabling a quick connection between the main vehicle body 10 and the connector. The connector 20 includes a mounting plate 21 and a support plate 23. The mounting plate 21 is vertically arranged, with its upper end bent to one side to form a first hook 211. This first hook 211 is adapted to the first mounting slot 111 of the main vehicle body 10, thereby achieving a detachable connection between the connector 20 and the main vehicle body 10, ensuring the stability of the connection while facilitating disassembly and reassembly. The support plate 23 is horizontally arranged on the side opposite to the mounting plate 21 and the first hook 211, used to support the extension platform 31 of the sub-vehicle body 30. The presence of the support plate 23 allows the sub-vehicle body 30 to be stably connected to the main vehicle body 10. The sub-body 30 further includes an extended platform 31 and support legs 32. One end of the extended platform 31 rests on the support plate 23 of the connector 20, increasing the usable area of ​​the service vehicle and making it suitable for more scenarios and needs. The support legs 32 in the sub-body 30 are located at the end of the extended platform 31 away from the main body 10, and together with the main body 10, they support the extended platform 31, ensuring the stability and balance of the entire service vehicle. At the same time, the design of the support legs 32 ensures that the extended platform 31 and the top of the main body 10 are at the same level, guaranteeing comfort and convenience of use.

[0032] Furthermore, the main vehicle body 10 features a rectangular three-dimensional frame 11, providing a stable structural foundation. The storage tray 12 can be used to store or display items, and the wheels 13 allow the main body to move, improving ease of use. These wheels 13 can be self-locking casters. Therefore, the main vehicle body 10 in this application can function as an independent unit for service operations.

[0033] Furthermore, a first mounting slot 111 is provided on the periphery of the top edge of the vehicle frame 11, meaning that when the vehicle frame 11 is a rectangular three-dimensional design and the top edge has four sides, the first mounting slot 111 is provided on the periphery of each of the four sides. The connector 20 can be mounted on one or more of its sides to further connect to the sub-vehicle body 30.

[0034] Therefore, in the technical solution of this application, users can freely combine and disassemble the various parts according to actual needs, and use the main body 10 or the combination of the main body 10 and the sub-body 30 to meet the usage needs in different scenarios.

[0035] In some embodiments, the first hook groove 111 is obliquely downward and extends inward from the surface of the top frame; and a raised rib (not shown in the figure) is provided in the first hook groove 111, and a folded portion (not shown in the figure) is also formed at the end of the first hook 211, the folded portion being used to grip the raised rib after the first hook 211 is inserted into the first hook groove 111.

[0036] In this embodiment, the first hook groove 111 extends diagonally downward from the surface of the top frame inward, which can provide a certain guiding effect for the first hook 211, making the first hook 211 smoother during insertion, and also helps to prevent the hook from accidentally falling off.

[0037] Furthermore, a raised rib is provided within the first hook groove 111, and a folded portion is formed at the end of the first hook 211, so that the first hook 211 can grip the raised rib after being inserted into the first hook groove 111. This further creates a "locking" effect, firmly fixing the first hook 211 within the hook groove. This helps prevent the first hook 211 from slipping or deforming under force, further enhancing the stability of the connection.

[0038] In some embodiments, a locking structure is also provided between the support plate 23 and the extension platform 31. The locking structure is used to lock / unlock the relative position between the support plate 23 and the extension platform 31 after the extension platform 31 is attached to the support plate 23. Thus, the user can fix or release the extension platform 31 as needed through the locking structure to adjust the overall layout of the service vehicle.

[0039] like Figures 2-4As shown, the locking structure includes a locking hole 231 on the support plate 23 and a locking knob 311 disposed on the bottom of the extension platform 31 and abutting the locking hole 231. The transverse diameter of the locking hole 231 is larger than its longitudinal diameter, and the size of the locking knob 311 matches the transverse diameter of the locking hole 231. The knob passes through the locking hole 231 and, upon rotation, clamps the support plate 23 between the locking knob 311 and the bottom surface of the extension platform 31. The working principle of the locking structure is as follows:

[0040] When the extension platform 31 is precisely aligned and overlapped with the support plate 23, the locking knob 311 passes through the locking hole 231. The user then rotates the locking knob 311 to create a clamping force between it and the extension platform 31. Because the lateral diameter of the locking hole 231 is larger than its longitudinal diameter, the locking knob 311 cannot be disengaged after rotation. This securely clamps the support plate 23, effectively fixing the extension platform 31 to it. This locking mechanism design allows the user to lock or unlock the extension platform 31 with a simple rotation, without the need for additional tools or complicated steps, making it convenient, efficient, and safe.

[0041] See Figure 3 As shown, in some embodiments, the periphery of the extended platform 31 is also provided with a first mounting groove 111 for assembling the connector 20.

[0042] In this embodiment, a first mounting slot 111 is also provided along the periphery of the extended platform 31, so that the connector 20 can be assembled using these first mounting slots 111, and the sub-vehicle body 30 can be further assembled using the connector 20. That is, this application can further assemble the sub-vehicle body on the basis of the sub-vehicle body, further enhancing the flexibility and scalability of the service vehicle, and providing users with more choices and possibilities.

[0043] See Figure 3 As shown, in some embodiments, a second hooking groove 112 is also provided on the periphery of the top edge and / or the extended platform 31 in the vehicle frame 11. The second hooking groove 112 is positioned relatively lower than the first hooking groove 111. The second hooking groove 112 is used to hook a baffle (not shown in the figure). A second hook adapted to the second hooking groove 112 is provided on the baffle.

[0044] In this embodiment, the attached baffle can be used to shield the space below the extended platform 31 or items within the vehicle frame 11. This effectively protects the goods inside the service vehicle from external environmental factors such as wind, rain, and dust, and also protects privacy below the extended platform 31.

[0045] The second mounting slot 112 is positioned lower than the first mounting slot 111, ensuring that attaching the baffle does not interfere with the use of the first mounting slot 111. Furthermore, the baffle is equipped with a second hook that fits into the second mounting slot 112, allowing the baffle to be easily attached to the mounting slot.

[0046] See Figure 3 and Figure 5 As shown, in some embodiments, the support leg 32 is hinged to the bottom surface of the extension platform 31, and a state holding mechanism 40 is also provided between the support leg 32 and the extension platform 31. The state holding mechanism 40 is used to keep the support leg 32 in an unfolded state or a folded storage state.

[0047] In this embodiment, the state-holding mechanism 40 is used to keep the legs 32 in an unfolded or folded state, which improves the stability and portability of the service vehicle. For example, when the sub-body 30 is needed, the user unfolds the legs 32. At this time, the state-holding mechanism 40 ensures that the legs 32 will not loosen or fold in the unfolded state, thus providing the user with stable and safe service. When the sub-body 30 is not needed, the user can fold the legs 32 to reduce the space occupied by the sub-body 30.

[0048] In one specific embodiment, the state-holding mechanism 40 comprises multiple components, including a support member 42, a pressing member 41, and an elastic drive member 43. Specifically, the pressing member 41 is hinged to the bottom of the extension platform 31. The pressing member 41 consists of two main parts: a drive section 411 and a pressing section 412, located on either side of the hinge point. To ensure the stability and functionality of the mechanism, the elastic drive member 43 is positioned between the drive section 411 and the extension platform 31. Its main function is to provide a continuous elastic force, ensuring that the pressing section 412 maintains a stable tendency to press against the extension platform 31. Furthermore, to achieve a more precise control and locking mechanism, two locking parts, namely a first locking part 411 and a second locking part 412, are provided at intervals on the pressing section 412. One end of the support member 42 is hinged to the support leg 32, while the other end can be locked to either the first locking part 411 or the second locking part 412.

[0049] This design allows the state-holding mechanism 40 to have two different stable states. Because the first locking part 411 is closer to the hinge point between the support leg 32 and the extended platform 31 than the second locking part 412, when the support member 42 is locked with the first locking part 411, the support leg 32 will be in the extended state, providing stable support and a platform for the sub-body 30. Conversely, when the support member 42 is locked with the second locking part 412, the support leg 32 will be in the folded storage state, which effectively saves space and facilitates carrying and storage. During operation, the user can switch between the two states by rotating the pressing section 412 to drive the support member 42. The end of the pressing section 412 away from the driving section can be equipped with a lever for easy and comfortable operation.

[0050] The support member 42 includes two mirror-designed connecting rods with identical length, diameter, and curvature, ensuring balance and stability when hinged to the support leg 32. A pressure bar is provided between the ends of the two connecting rods near the pressure member 41, connecting the two rods together to form a single integrated structure. Both the first locking part 411 and the second locking part 412 are semi-circular grooves adapted to the shape of the pressure bar, ensuring a tight fit against the inner wall of the groove when inserted, thus providing a stable locking force.

[0051] See Figure 3 As shown, in some embodiments, a handle 312 is provided on the bottom surface of the extended platform 31. The design of the handle 312 allows the user to easily grasp the sub-carriage body 30, thereby facilitating its movement and transfer. In this application, the handle 312 may also be designed with a groove for easy gripping, reducing pressure on the palm and improving grip comfort. During use, the groove design of the handle 312 allows the user to carry the sub-carriage body 30 for extended periods without experiencing fatigue, improving the overall user experience. Two handles 312 are provided opposite each other.
