[0006] The technical solution adopted by the present application to solve its technical problems is a tire testing device for simulating a field road surface, including: a bracket; a roller for simulating a field road surface, with a motor provided on one side of the roller; a tire seat provided on the bracket for placing a tire; a driving device provided on the bracket for driving the tire seat to move towards the roller direction and controlling the distance between the tire on the tire seat and the roller; a protective frame, on which at least four protective layers are provided, and the protective frame is rotatably provided on the driving device for preventing the tire from flying out; the protective frame is rotated to make the protective frame enter an upright state and a flat state.

[0007] In some embodiments, a locking block is provided on the protective frame, and a bolt lock is installed above the driving device, and a bolt is provided inside the bolt lock.

[0008] In some embodiments, when the protective frame is in the upright state, the locking block is located above the bolt lock, and the bolt is inserted at the locking block to lock the protective frame in the upright state.

[0009] In some embodiments, the tire seat includes a base and a support table, the base cooperates with the driving device to move, and a pair of support tables are provided on the base.

[0010] In some embodiments, a chute is obliquely provided on the support table.

[0011] In some embodiments, the outer peripheral contact surface of the roller is made of a non-smooth rough material.

[0012] In some embodiments, the driving device is any one of an electric push rod, an oil cylinder, and a cylinder.

[0013] The beneficial effects of the present application are as follows: The driving device is used to drive the tire seat, so that the tire on the tire seat approaches the roller close to the road surface material that is rotating, to simulate the use of the tire on the actual road surface. Moreover, the method of driving the tire seat by the driving device is more flexible and can adapt to tires of different sizes and specifications. At the same time, the protective frame in the upright state can prevent the tire from flying out during the tire test and affecting people or objects around. When the tire needs to be disassembled or installed, only need to put down the protective frame to enter the flat state, effectively improving the convenience during use. Description of the Drawings

[0020] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present application. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the fact that those of ordinary skill in the art can implement it. When the combination of the technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection of the present application.

[0021] In the embodiments of the present application, please refer to Figures 1-4 As shown, the present application provides a tire test device for simulating a field road surface, which mainly includes: a bracket 1; a roller 2 for simulating a field road surface, and a motor 21 is arranged on one side of the roller 2; a tire seat 3 is arranged on the bracket 1 for placing a tire; a driving device 4 is arranged on the bracket 1 for driving the tire seat 3 to move towards the roller 2 and controlling the distance between the tire on the tire seat 3 and the roller 2; a protective frame 5, and at least four protective layers 51 are arranged on the protective frame 5. The protective frame 5 is rotatably arranged on the driving device 4 to prevent the tire from flying out; the protective frame 5 is rotated to make the protective frame 5 enter an upright state and a flat state.

[0022] Specifically, after the tire is placed on the tire seat 3, when the protective frame 5 is rotated to the upright state, the protective layer on the protective frame 5 will cover as much as possible the path where the tire may fly out, effectively preventing the possibility of the tire flying out and hurting people. Then, the motor 21 can be started to make the roller 2 rotate. The driving device 4 drives the tire seat 3 towards the roller 2 until the roller 2 contacts the tire on the tire seat 3. The tire will rotate simultaneously with the roller 2 under the action of friction, reaching the degree of simulating the field road surface test.

[0023] Next, some preferred / improved embodiments based on the above embodiments will be further elaborated. Any one or a combination of multiple of the following embodiments can be selected.

[0024] Refer to Figure 3 As shown, a lock block 52 is arranged on the protective frame 5, and a pin lock 41 is installed above the driving device 4, and a pin 42 is arranged in the pin lock 41; when the protective frame 5 is in the upright state, the lock block 52 is located above the pin lock 41, and the upright protective frame 5 is locked by inserting the pin 42 at the lock block 52. With this setting, during the rotation of the tire, the protective frame 5 can withstand greater pressure in the upright state, preventing the protective frame 5 from tilting backward and returning to the flat state due to vibration or slight impact.

[0025] Referring to Figure 1 as shown, the tire seat 3 includes a base 31 and a support platform 32. The base 31 cooperates with the driving device 4 for movement. A pair of the support platforms 32 are arranged on the base 31. An inclined chute 321 is formed on the support platform 32. The chute 321 can facilitate the installation and removal of the tire. At the same time, the tire shaft is placed in the chute 321, which can better simulate the state of the tire on the actual road surface, and the inclined design can, to a certain extent, prevent the tire from flying out.

[0026] Specifically, in order to simulate the actual road surface, the outer peripheral contact surface of the roller 2 is made of a non-smooth rough material.

[0027] Preferably, the driving device 4 adopts any one of an electric push rod, an oil cylinder, and a cylinder. Specifically in this embodiment, an electric push rod is selected as the driving device 4. Compared with the oil cylinder and the cylinder, the electric push rod has a more precise control of the propulsion distance and can more effectively assist the tire to complete the simulation test of the actual road surface.

[0028] So far, various embodiments of the present application have been described in detail. In order to avoid obscuring the concept of the present application, some details well known in the art are not described. Those skilled in the art can fully understand how to implement the technical solutions disclosed herein based on the above description.

[0029] Finally, it should be noted that the above are only the preferred embodiments of the present application. The foregoing embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the various embodiments of the present application.
