[0023] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only a part of the embodiments of the utility model, rather than all the embodiments. The components of the embodiments of the utility model described and shown in the drawings herein can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the utility model provided in the drawings is not intended to limit the scope of the claimed utility model, but only represents selected embodiments of the utility model. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative efforts belong to the scope of protection of the utility model.

[0024] As shown in Figures 1-4 The utility model provides a kind of auxiliary wheel group structure, including installation frame 1, the outer wall of installation frame 1 is fixedly equipped with mounting plate 7, the surface of mounting plate 7 is equipped with mounting hole, the inner wall of installation frame 1 is vertically rotatably connected with screw rod 2, the outer circumferential surface of screw rod 2 is threadedly connected with sliding block 3, sliding block 3 is slidably connected with installation frame 1, the surface of sliding block 3 is fixedly equipped with the bending plate 4 sliding through installation frame 1, the surface of bending plate 4 is slidably connected with rectangular frame 5, the outer wall of rectangular frame 5 is rotatably connected with wheel 6, when needing to use auxiliary wheel group on the frame of different vehicle types, mounting plate 7 is fixed on the frame using U-shaped bolt through mounting hole, then rotating screw rod 2, screw rod 2 will drive sliding block 3 to slide along the inner wall of installation frame 1 by thread, sliding block 3 moves will drive bending plate 4 to move, bending plate 4 moves will make rectangular frame 5 drive wheel 6 to move, to adjust the height of wheel 6, to make wheel 6 adapt to the frame of different vehicle types, improve the practicability of auxiliary wheel group.

[0025] In the above scheme, when wheel 6 hits obstacle during driving, wheel 6 will move upward quickly, causing rectangular frame 5 to hit bending plate 4 and deform, affecting the normal sliding of rectangular frame 5, so it is necessary to reduce the collision intensity between rectangular frame 5 and bending plate 4, in the embodiment, the surface of bending plate 4 is fixedly equipped with spring 8, spring 8 extends downward along the vertical direction and is connected with rectangular frame 5, when wheel 6 moves upward, rectangular frame 5 will compress spring 8, spring 8 will buffer rectangular frame 5, when the vehicle drives normally, spring 8 can also support bending plate 4 by its own elasticity, and then support the frame.

[0026] Specifically, since spring 8 is in a bare state, spring 8 is easy to be damaged by hitting obstacle during vehicle driving, so it is necessary to protect spring 8, and the specific setting is that the outer wall of rectangular frame 5 is fixedly equipped with protective plate 9, spring 8 is located in protective plate 9, protective plate 9 penetrates bending plate 4, protective plate 9 can shield spring 8, to prevent spring 8 from contacting with obstacle, thereby prolonging the service life of spring 8.

[0027] Further, in order to prevent the rectangular frame 5 from reciprocating sliding due to the elastic force of the spring 8, affecting the stability of the vehicle frame, in the embodiment, the sliding process of the rectangular frame 5 is damped, and specifically, the damping plate 10 is fixedly arranged in the bent plate 4 and abuts against the inner wall of the rectangular frame 5, so that the damping plate 10 can damp the rectangular frame 5 when the rectangular frame 5 slides along the surface of the bent plate 4, thereby preventing the rectangular frame 5 from continuously reciprocating sliding.

[0028] In addition, in order to improve the comfort of the occupant, the embodiment supports the feet of the occupant, and specifically, the outer wall of the mounting frame 1 is rotationally connected with the pedal 11, the surface of the pedal 11 is fixedly connected with the clamping block 12, the clamping block 12 abuts against the outer wall of the mounting frame 1, the clamping block 12 can limit the position of the pedal 11 when the pedal 11 is rotated to the horizontal state, and at this time, the occupant can step on the pedal 11, thereby supporting the feet of the occupant.

[0029] Since the surface of the pedal 11 is relatively smooth, it is difficult for the occupant to step stably when stepping, and therefore it is necessary to increase the friction of the surface of the pedal 11, and specifically, the through hole 13 is formed in the surface of the pedal 11, and the vertical section of the through hole 13 is trapezoidal, so that the roughness of the surface of the pedal 11 is increased, thereby improving the friction of the pedal 11, and the through hole 13 with the vertical section being trapezoidal can facilitate the falling of the attached soil, thereby reducing the maintenance difficulty.

[0030] When the pedal 11 is not used, the pedal 11 is expanded and is prone to colliding with external articles, and therefore it is necessary to facilitate the folding of the pedal 11, and specifically, the magnet piece 14 is fixedly arranged in the mounting frame 1, the pedal 11 is an iron plate, the pedal 11 abuts against the magnet piece 14 when the pedal 11 is rotated to the vertical state, the magnet piece 14 attracts the pedal 11 by means of the magnetic force, thereby limiting the position of the pedal 11, and avoiding the collision of the pedal 11 with external articles.

[0031] In the description of the present application, the terms "first", "second", "another", "yet another" are only used for the purpose of description, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features limited by "first" and "second" can explicitly or implicitly include one or more features. In the description of the embodiments of the present application, the meaning of "multiple" is two or more, unless otherwise specifically limited.

[0032] In the description of the utility model, it is necessary to explain, unless another explicit provision and limitation, term "link", "connection" should do broad sense understanding, for example, can be fixed connection, also can be detachable connection, or integrally connected;Can be mechanical connection, also can be electrical connection;Can be directly connected, also can be indirectly connected through intermediate medium.

[0033] Although the embodiments of the utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, replacements and variations can be made to these embodiments without departing from the principles and purposes of the utility model, the scope of the utility model is defined by the claims and its equivalents.
