[0029] The following will be combined with the accompanying drawings in the embodiment of the present invention to clearly and completely describe the technical solutions in the embodiment of the present invention. Figures 1 to 2 One embodiment of the present invention provides a four-wheeled vehicle, which includes a front wheel detachable leg connection structure for easy carrying and detaching the legs, wherein the front wheel detachable leg connection structure for easy carrying and detaching the legs includes: a main frame 10 and a detachable leg 20.

[0030] See also Figures 1 to 3 The main frame 10 is provided with a mounting channel 11 and a receiving channel 12. The mounting channel 11 is provided with a first positioning hole 111, and the receiving channel 12 is provided with a second positioning hole 121. The main frame 10 may also be the entire vehicle frame or a portion thereof. For example, in this embodiment, the four-wheeled vehicle further includes a main frame, and the main frame 10 is a front wheel bracket for mounting the front wheel. The front wheel bracket is provided on the main frame, and the mounting channel 11 and the receiving channel 12 are provided on the front wheel bracket. The front wheel bracket is typically a hollow tubular structure, and the mounting channel 11 may be formed inside the tubular structure.

[0031] See also Figure 4 The detachable leg 20 is provided with a leg support plate 21 and an elastic positioning member 22.

[0032] See also Figure 1 、 Figure 4 and Figure 5 When the front wheel detachable leg connection structure for easy portability is in the assembled state, the detachable leg 20 is detachably inserted into the installation channel 11, and the elastic positioning member 22 is positioned and matched with the first positioning hole 111. At this time, the patient's legs can be placed on the leg support plate 21.

[0033] See also Figure 2 、 Figure 6 and Figure 7 When the front wheel detachable leg connection structure for easy portability is in a retracted state, part of the detachable leg 20 is detachably inserted into the storage channel 12, and the elastic positioning member 22 is positioned and matched with the second positioning hole 121. The position of the storage channel 12 can be pre-designed so that when the detachable leg 20 is installed in the storage channel 12, the detachable leg 20 is arranged in a suitable position, so that the detachable leg 20 is not likely to interfere with the patient's use of other functions of the four-wheeled vehicle, and the detachable leg 20 can be folded relative to the four-wheeled vehicle without interfering with the patient getting on and off the vehicle. The detachable leg 20 can also be stably stored without colliding with the environmental structure in the application scenario.

[0034] The positioning structure is relatively simple and can achieve quick positioning, making the disassembly and assembly operations easier. Moreover, the front wheel detachable leg connection structure is easy to carry. In the assembled state and the folded state, the detachable leg 20 is positioned and matched by the elastic positioning part 22, which enhances the versatility of the elastic positioning part 22 and helps to simplify the structure of the detachable leg 20.

[0035] See also Figure 8 In some optional embodiments, the insertion port of the installation channel 11 is provided with a first guiding bevel 112. When the detachable leg 20 enters the installation channel 11, the first guiding bevel 112 presses against the elastic positioning member 22 and drives the elastic positioning member 22 to produce elastic deformation. There is no need for manual pressing of the elastic positioning member 22. The elastic positioning member 22 can be squeezed by the first guiding bevel 112, thereby preventing the human hand from being clamped between the detachable leg 20 and the main frame 10 or between the detachable leg 20 and the inner wall of the installation channel 11, thereby improving safety and making installation more convenient.

[0036] In some optional embodiments, the insertion port of the installation channel 11 is provided with a second guiding bevel 122. When the detachable leg 20 enters the storage channel 12, the second guiding bevel 122 presses against the elastic positioning member 22 and drives the elastic positioning member 22 to produce elastic deformation. There is no need for manual pressing of the elastic positioning member 22. The elastic positioning member 22 can be squeezed by relying on the second guiding bevel 122, thereby preventing the human hand from being clamped between the detachable leg 20 and the main frame 10 or between the detachable leg 20 and the inner wall of the storage channel 12, thereby improving safety and making installation more convenient.

[0037] In some optional embodiments, the elastic positioning member 22 is a positioning marble. The positioning marble typically includes a marble and an elastic pressure plate. The elastic pressure plate is installed in the detachable leg 20. The marble extends from the inside of the detachable leg 20 to the outside of the detachable leg 20, and the elastic pressure plate presses against the marble. The principle of the positioning marble is well known to those skilled in the art and will not be described in detail here. Of course, the elastic positioning member 22 can also adopt other structures and is not limited to the positioning marble. For example, a metal spring can also be used.

[0038] In some optional embodiments, the first positioning hole 111 is connected to the outside of the mounting channel 11, and the first positioning hole 111 gradually expands in the direction toward the outside of the mounting channel 11. When the detachable leg 20 needs to be removed from the mounting channel 11, the elastic positioning member 22 in the first positioning hole 111 can be squeezed into the mounting channel 11, so that the elastic positioning member 22 is separated from the first positioning hole 111. The gradually expanding first positioning hole 111 makes it easier for people to squeeze the elastic positioning member 22, improves operability, and prevents people from being clamped between the elastic positioning member 22 and the inner wall of the first positioning hole 111.

[0039] In some optional embodiments, the second positioning hole 121 is connected to the outside of the storage channel 12, and the second positioning hole 121 gradually expands in the direction toward the outside of the storage channel 12. When the detachable leg 20 needs to be removed from the storage channel 12, the elastic positioning member 22 in the second positioning hole 121 can be squeezed into the storage channel 12, so that the elastic positioning member 22 is separated from the second positioning hole 121. The gradually expanding second positioning hole 121 makes it easier for people to squeeze the elastic positioning member 22, improves operability, and prevents people from being clamped between the elastic positioning member 22 and the inner wall of the second positioning hole 121.

[0040] In some optional embodiments, the storage channel 12 extends toward the top of the main frame 10, which is convenient for carrying the front wheel of the detachable leg. When the detachable leg connection structure is in the retracted state, the detachable leg 20 is stored above the storage channel 12, so that the detachable leg 20 can extend toward the top of the main frame 10, which is beneficial for supporting and maintaining the balance of the detachable leg 20. In this embodiment, the detachable leg 20 is arranged on the side of the armrest, which facilitates the folding of the detachable leg 20 relative to the main frame 10.

[0041] In some optional embodiments, the mounting channel 11 extends toward the front side of the main frame 10 , facilitating the removal of the legs 20 extending toward the front side of the main frame 10 , so that the leg support portion is arranged at a suitable position on the front side of the main frame 10 .

[0042] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
