[0003] Most of the current wheelchair robots are of an integrated structure, and the seats on the wheelchairs are fixed on the wheelchair frame and cannot be removed. Therefore, when transporting the wheelchair robot, the wheelchair robot occupies a large area and is inconvenient to transport. Therefore, a wheelchair robot with a detachable wheelchair and a base is proposed. Utility Model Content

[0006] The limit assembly includes a motor, which is fixedly mounted on the left side wall of the cavity, a bidirectional threaded rod is fixedly mounted on the output shaft of the motor, and threaded blocks are threadedly connected to the outside of the left and right sides of the bidirectional threaded rod, a slider is fixedly mounted on the threaded block, a slide groove is provided on the base, the slider is slidably connected to the inside of the slide groove, and a limit plate is fixedly mounted on the threaded block;

[0007] A connecting plate is fixedly installed at the bottom of the seat, and a limiting groove is arranged on the connecting plate to facilitate the insertion of the limiting plate.

[0008] Furthermore, the sliding blocks are located on the left and right sides of the threaded block; and the sliding grooves are located on the left and right sides of the bidirectional threaded rod.

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-3A wheelchair robot in this embodiment includes a wheelchair robot body 1, a base 12 is fixedly installed on the top of the wheelchair robot body 1, a limiting component is installed inside the base 12, and a seat 2 is installed above the base 12.

[0023] The limit assembly includes a motor 13, which is fixedly mounted inside the base 12. A bidirectional threaded rod 14 is fixedly mounted on the output shaft of the motor 13. The outside of the left and right sides of the bidirectional threaded rod 14 are both threadedly connected with threaded blocks 9, and sliders 8 are fixedly mounted on the left and right sides of the threaded blocks 9. The base 12 is provided with two slide grooves 10, which are located on the left and right sides of the bidirectional threaded rod 14. The slider 8 is slidably connected inside the slide groove 10, and the two threaded blocks 9 are fixedly mounted on the opposite sides of each other with a limit plate 16. Further, the limit plate 16 is located on both sides of the bidirectional threaded rod 14 for better fixation.

[0024] like Figure 4 As shown, a connecting plate 7 is fixedly installed at the bottom of the seat 2, and a groove is provided at the bottom of the connecting plate 7, and a bidirectional threaded rod 14 is located inside the groove. Two limiting grooves 15 are provided on the connecting plate 7, and one end of the limiting plate 16 away from the thread block 9 is inserted inside the limiting groove 15. The limiting groove 15 on the connecting plate 7 is in the same direction as the bottom groove. Preferably, in order to fix the connecting plate 7 and the limiting plate 16 to each other, the connecting plate 7 is arranged on the left and right sides of the bottom of the seat 2.

[0025] It should be noted that the sliding connection of the slider 8 in the slide groove 10 limits the threaded block 9, so that when the bidirectional threaded rod 14 rotates forward or reversely, the two threaded blocks 9 can only move in opposite directions or relative to each other.

[0026] In this embodiment, armrests 3 are installed on the front and back of the seat 2. The front side of the front armrest 3 is rotatably connected to a rotating arm 5. The inside of the rotating arm 5 is rotatably connected to a smart panel 4. The smart panel 4 is electrically connected to the motor 13.

[0027] It should be noted that controlling the motor 13 through the smart panel is a conventional technical means for those skilled in the art, and the control method involved will not be described in detail here.

[0028] It should be noted that the motor 13 is a servo motor, the threads on the two sides of the outside of the bidirectional threaded rod 14 are in opposite directions, and the two threaded blocks 9 are threadedly connected to the two sides of the outside of the bidirectional threaded rod 14 .

[0029] The right end of the bidirectional threaded rod 14 is rotatably connected to the inside of the base 12 via a bearing.

[0030] In this embodiment, two installation grooves are formed on the top of the base 12 , and the bottom of the connecting plate 7 passes through the installation grooves and extends to the inner bottom of the base 12 .

[0031] In this embodiment, positioning blocks 6 are fixedly installed on the left and right sides of the bottom of the seat 2, and positioning grooves 11 are opened on the left and right sides of the top of the base 12. The positioning blocks 6 are clamped in the inside of the positioning grooves 11, and the positioning blocks 6 play a positioning role, so that the connecting plate 7 can be better aligned with the installation groove.

[0032] The working principle of the above embodiment is as follows: when separating the seat 2 and the base 12, the bidirectional threaded rod 14 is driven to rotate by operating the control motor 13 on the smart panel 4. Under the limiting action of the sliding connection between the slider 8 and the slide groove 10, the two threaded blocks 9 are moved relative to each other, so that the limiting plate 16 can be pulled out from the limiting groove 15, thereby taking the connecting plate 7 out of the base 12, and pulling the positioning block 6 out of the positioning groove 11, so that the seat 2 can be separated from the base 12, thereby facilitating transportation. On the contrary, by reversing the bidirectional threaded rod 14, the two threaded blocks 9 move in opposite directions, and the limiting plate 16 is inserted into the inside of the limiting groove 15 to limit the connecting plate 7, so that the seat 2 and the base 12 can be connected and fixed.

[0033] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "comprise a ..." do not exclude the existence of other identical elements in the process, method, article or device including the elements.

[0034] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
