[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of this application. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0017] The following is in conjunction with the appendix Figure 1-4 This application provides a further detailed description. An embodiment of this application discloses a simple tire impact detection device, including a frame 1. A tire mounting base 2 is connected to the bottom of the frame 1 for connecting the tire to be tested. A pendulum mounting base 3 is located above the tire mounting base 2 and is connected to the frame 1. An impact pendulum 4 is rotatably connected to the pendulum mounting base 3, with its end rotating towards the tire mounting base 2. Impact detection of the tire is achieved by the end of the impact pendulum 4 impacting the tire connected to the tire mounting base 2. The pendulum mounting base 3 also includes an angle monitor 5 for measuring the rotation angle of the impact pendulum 4. The angle monitor 5 determines the rotation angle of the impact pendulum 4, thereby determining the impact force at the end of the impact pendulum 4.

[0018] Furthermore, the angle monitor can be a conventional device for monitoring angles, such as an angle sensor. To simplify the equipment, eliminate the cost disadvantages caused by reliance on electronic devices, and avoid redundancy in electronic components, in this embodiment, the angle monitor 5 is an angle scale, such as an angle ruler or angle dial. The angle of the impact pendulum 4 is determined by the position of its rotation relative to its position on the angle scale.

[0019] Furthermore, since the impact pendulum 4 typically has a relatively thick connecting rod, it is difficult to accurately determine the angle when it corresponds to the angle scale. In this embodiment, the impact pendulum 4 is hinged to the pendulum mounting base 3 via a hinge shaft, and a pointer 6 is fixedly connected to the hinge shaft. The extension direction of the pointer 6 is the same as the extension direction of the impact pendulum 4, and the indicating end of the pointer 6 points to the angle scale. The pointer 6 is used to accurately indicate the rotation angle value of the impact pendulum 4 relative to the angle scale.

[0020] Furthermore, to ensure that the rotation angle of pointer 6 corresponds to the rotation angle of impact pendulum 4, impact pendulum 4 is provided with pendulum markings 401. The pointer 6 corresponds to the pendulum markings 401 in both position and angle. Specifically, a pendulum marking 401 is marked in the extension direction of impact pendulum 4, and the end point of the extension line of pendulum marking 401 coincides with the axis of the hinge shaft. Then, the center line of the extension direction of pointer 6 is aligned with the radial section angle of the hinge shaft with the pendulum marking 401, so that the angle indicated by pointer 6 directly represents the rotation angle of impact pendulum 4. At the same time, the angular offset of pointer 6 relative to pendulum markings 401 can be used to determine the corresponding position where pointer 6 or impact pendulum 4 has disengaged, thus confirming the effect of equipment malfunction.

[0021] Furthermore, the tire mounting base 2 for connecting the tire to be tested includes a support plate 201. The support plate 201 has a connecting hole, and a support column 202 for connecting the tire is connected to the connecting hole. After the support column 202 is connected to the connecting hole of the support plate 201 by interference fit or threaded connection, the tire to be tested is connected to the support column 202, which fixes the tire to be tested at the end of the rotation angle of the impact pendulum 4, so that the impact surface of the tire to be tested can be impacted by the end of the impact pendulum 4. The support plate 201 can be arbitrarily adjusted to a suitable angle according to actual needs, for example, at... Figure 4 In the illustrated embodiment, the surface of the support plate 201 is perpendicular to the ground, allowing the fixed tire to simulate its actual installation angle / posture during use. In this case, the tire mounting base 2 can also be equipped with a base to which the support plate 201 is hinged, allowing the surface of the support plate 201 to change its angle relative to the ground, enabling the tire to be tested to undergo impact testing at various angles / postures. Furthermore, the base can be divided into a first base and a second base, rotatably connecting the first and second bases to further expand the angle adjustment range of the support plate 201 and the tire to be tested, achieving more complex testing postures. Simultaneously, the support column 202 can also be connected to an intermediate connector based on the specifications and type of the tire to be tested, and then connected to the tire through the intermediate connector.

[0022] Furthermore, based on the different models, specifications, and sizes of the tires to be tested, the connecting hole is a strip-shaped hole, and the support column 202 is equipped with a limiting plate 203. After the support column 202 passes through the strip-shaped hole, a locking nut 204 is connected. By controlling the movement of the locking nut 204 towards the limiting plate 203, the locking nut 204 and the limiting plate 203 together clamp the support plate 201. This allows the position of the support column 202 relative to the support plate 201 to move along the extension direction of the strip-shaped hole, thereby changing the relative position of the tire to be tested relative to the support plate 201. This enables tires of different models, specifications, and sizes to be tested, improving the versatility of this invention.

[0023] Frame 1 can be made of conventional materials such as steel pipes and reinforcing bars, and connected using conventional techniques such as welding and riveting, or it can be integrally molded. The pendulum fixing seat 3 and the tire fixing seat 2 can also be fixedly connected to frame 1 using conventional techniques such as threaded connection, riveting, and welding.

[0024] Working principle: The tire to be tested is fixedly connected to the tire mounting base 2. An appropriate impact pendulum 4, selected according to the tire's specifications, is hinged to the pendulum mounting base 3. The end of the impact pendulum 4 is pulled away from the tire. The rotation angle of the impact pendulum 4 is determined by the angle monitor 5, thus determining the impact force. The impact pendulum 4 is released, and its end rotates towards the tire under gravity, impacting it. The changes in the tire are observed visually or by other methods to determine the impact test result.
