[0002] Strictly speaking, tire pressure refers to the air pressure inside the tire. Tire pressure plays a crucial role in a vehicle's performance and power. For example, the load a vehicle can carry depends on its tire pressure; furthermore, when a vehicle travels at a constant speed on a level road, it must overcome rolling resistance from the ground and air resistance, and tire pressure significantly affects the rolling resistance coefficient. Therefore, during vehicle development, tire pressure testing is necessary to design appropriate tire pressures based on the vehicle's overall performance and power requirements.

[0025] Furthermore, for any single technical feature described or implied in the embodiments mentioned herein, or any single technical feature shown or implied in the accompanying drawings, this application still allows for any combination or deletion of these technical features (or their equivalents) without any technical obstacle, and thus these further embodiments according to this application should also be considered within the scope of this description.

[0026] It should also be noted that terms such as "setup" should be interpreted broadly. For example, it can refer to a fixed connection, a detachable connection, or an integral part; it can refer to a direct connection or an indirect connection through an intermediate medium. Unless otherwise explicitly defined, those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0027] Reference Figures 1-2 A tire pressure testing device for automobiles includes a support assembly 1, a drive component 2, a simulation component 3, a detection component 4, and a control assembly 5. During testing, the support assembly 1 is placed on the ground to support the drive component 2, the simulation component 3, and the detection component 4. The drive component 2 is mounted on top of the support assembly 1, and its drive end is connected to the simulation component 3. The drive component 2 drives the simulation component 3 to rotate, simulating the movement of an automobile tire. The detection component is mounted on one side of the simulation component 3 to detect tire pressure data during its operation. The control assembly 5 is signal-connected to the drive component 2 and the detection component 4, controlling the operation of the drive component 2 to control the speed of the simulation component 3. The detection component 4 outputs a detection signal to the control assembly 5 for easy monitoring by personnel.

[0028] By controlling the control component 5, the simulation component 3 can simulate the movement of a car tire. During this process, the detection component 4 detects the pressure of the simulated car tire during the movement of the simulation component 3 and feeds back the detection signal to the control component 5, thereby achieving the purpose of simulating the road test of the whole vehicle during the development process. Furthermore, according to the control of the control component 5, the simulation test of reversing and moving forward at different speeds can be realized.

[0029] Specifically, the support assembly 1 includes a support base 11 and a support rod 12. The support base 11 is plate-shaped and can be relatively heavy to provide support and stability. The support rod 12 is fixedly connected to one side of the support base 11, and the support rod 12 and the support base 11 can be perpendicular to each other. In this embodiment, the support rod 12 and the support base 11 can be connected by welding, integral molding, or bolting, as long as a stable connection between the two is ensured.

[0030] In this embodiment, the driving component 2 can be a rotary motor, specifically a rotary motor capable of forward and reverse rotation. The motor output shaft of the driving component 2 is fixedly connected to the center position of the simulation component 3, specifically by means of bolts or the like. The base of the driving component 2 is fixedly connected to the end of the support rod 12 away from the support base 11. In practical applications, the driving component 2 and other structures can be connected to a dedicated power supply and driving circuit to ensure the normal operation of the driving component 2 and other structures.

[0031] The simulation component 3 is configured as a rotating disk, the diameter of which is approximately equal to the diameter of the car tire to be simulated, in order to achieve more accurate simulation results. In this embodiment, the rotating disk is disc-shaped, simulating the shape of a car tire. Specifically, the rotating disk can be made of acrylic, preferably 3-5mm thick, which is lightweight, easy to move, and also saves costs. After receiving the control command, the drive component 2 can drive the rotating disk to reach the target vehicle speed to complete the simulation test and obtain test data. Here, the control command refers to the command output by the control component 5, which includes the running direction and running speed of the drive component 2.

[0032] In this embodiment, the motor output shaft of the drive component 2 can be fixedly connected to the simulation component 3 by bolts, so that the simulation component 3 can simulate the operation of a car tire under the drive of the drive component 2.

[0033] Reference Figure 1 and Figure 3 The detection element 4 can be an integrated structure of tire pressure sensor 41 and transmitter 42, with the tire pressure sensor 41 and transmitter 42 connected by a signal, and the transmitter 42 can be a wireless communication transmitter. The detection element 4 is directly installed on the periphery of the simulation element 3. In this embodiment, four detection elements 4 are provided and evenly distributed on the periphery of the simulation element 3 to more accurately detect tire pressure data. The tire pressure sensor 41 is used to detect the simulated tire pressure data and outputs the tire pressure data through the transmitter 42. Specifically, a connecting rod 43 is fixedly connected to one edge of the simulation element 3, and the connecting rod 43 is set perpendicular to the simulation element 3; the detection element 4 is fixedly connected to the end of the connecting rod 43 away from the simulation element 3. During the simulation of the running of a car tire, the detection element 4 detects the pressure and outputs a signal to the control component 5; the fixed connection can be achieved by bolts, adhesive bonding, or other fixing methods.

[0034] The control component 5 includes a motor controller 51 and a signal receiver 52. The motor controller 51 controls the drive unit 2 and can output commands for different driving directions and speeds. This allows operators to adjust the driving direction and speed of the drive unit 2, thereby simulating the reversing and forward movement of a car. Furthermore, adjusting the speed of the drive unit 2 allows for simulation of reversing and forward movement at different speeds. In actual simulated vehicle road tests, the reversing simulation can achieve speeds of 5-15 km / h; the forward simulation can achieve speeds of 5, 10, 15, 20, 25, 30, 35, 40, 45, 55, and 60 km / h.

[0035] The signal receiver 52 can be a receiver controller used for automotive tire monitoring. The input of the signal receiver 52 is connected to the transmitter 42, thus enabling wireless communication with the transmitter 42. The output of the signal receiver 52 can be connected to a display instrument or similar device, allowing operators to view the signals output by the testing components 4. The display instrument can be a monitor capable of receiving signals from the signal receiver 52. In practical applications, the signal receiver 52 can be directly connected to a testing computer, allowing operators to observe the tire pressure data output by the four testing components 4.

[0036] In this embodiment of the application, if the signal receiver 52 receives an analog signal, an analog-to-digital converter and an amplifier can be added so that staff can visually observe the tire pressure data.

[0037] In summary, the tire pressure testing device for automobiles provided in this application can be used during the development process to simulate the road test scenario of a whole vehicle and detect the tire pressure changes of automobile tires during reversing or moving forward; it can also be used in the absence of real vehicle resources to simulate the road test scenario of a real vehicle and provide simulation data for testing, which facilitates the analysis of whether the product can meet the design requirements.

[0038] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application.
