Description

Technical Field

[0001] This utility model relates to the field of automobile tire testing technology, and in particular to an automobile tire testing device. Background Technology

[0002] A vehicle tire inspection device is a device that uses sensors, image recognition and other technologies to monitor tire pressure, wear, cracks and other conditions in real time to ensure driving safety.

[0003] However, traditional tire inspection devices involve a cumbersome and complex tire loading and unloading process, requiring significant manpower and time to secure and remove tires, thus reducing the overall efficiency of the inspection work. Furthermore, the detection probes of traditional tire inspection devices have a fixed structure, which cannot be flexibly adjusted according to the size of different tires and the diverse needs of the inspection positions, thereby affecting the comprehensiveness and accuracy of the inspection and failing to meet diverse tire inspection requirements.

[0004] Prior art 1 (Chinese patent application number CN202120397370.9, application date 2021-02-23) discloses a quality inspection device for automobile tires, including an inspection box, an operating table fixed at the top center of the inspection box, a tire body mounted on the top of the operating table, an inspection probe mounted on one side of the top of the inspection box, a drive motor mounted on the side of the inspection box away from the inspection probe, and a limit component installed inside the inspection box. When the tire body needs to be inspected, the tire body is mounted on the operating table, the drive motor is started, and the drive motor drives the rotating shaft and worm gear to rotate synchronously. The worm and worm gear cooperate with each other to drive the tire body to rotate. The inspection probe performs a comprehensive inspection of the outer surface of the rotating tire body, improving the inspection efficiency of the tire body and making the installation and removal of the tire body more convenient and quick.

[0005] Prior art 2 (Chinese patent application number CN202322606100.6, application date 2023-09-25) discloses a tire positioning device for a car tire pressure detection device, including a housing, a support device fixedly connected to the middle of the upper bottom surface of the housing, and a rotating device fixedly connected to the middle of the lower top surface of the housing. The tire positioning device, by setting a positioning rod and a hydraulic rod, allows the tire to be fixed only by fixing the wheel hub, thereby avoiding clamping the tire and causing errors in the measurement of tire pressure. By setting a toothed sleeve, the detection device will not rotate when the tire is fixed. Utility Model Content

[0012] As a preferred embodiment of this utility model, a pair of guide posts are provided on one side of the movable plate, and guide sleeves are provided on the lifting plate at positions corresponding to the guide posts. A detection probe is provided on the movable plate.

[0013] Compared with the prior art, the above-mentioned technical solution of this utility model has the following beneficial technical effects: This invention features an inner wall support assembly. A motor drives a sprocket, which in turn drives a chain to rotate a second sprocket and a rotating shaft. This stable power transmission to the turntable ensures the turntable rotates the arc-shaped rods, achieving precise transmission of the support action. Furthermore, the arc-shaped rods around the turntable are connected to the arc-shaped support seats on the tire rack via connecting rods. Guide grooves guide the arc-shaped support seats, ensuring they reliably and stably support the inner wall of the tire, firmly fixing it to the tire rack and preventing tire movement during testing from affecting the results. Additionally, a servo motor drives the rotating seat to rotate, which in turn rotates the tire, allowing the testing probe to perform comprehensive tire inspection.

[0014] This invention features a probe adjustment assembly. A motor drives a gear to rotate, and the meshing of the gear and rack moves the rack along a guide rail. This, in turn, drives a lifting plate via a connecting frame to accurately adjust the vertical position of the detection probe, meeting the needs of different tire sizes and detection locations. Furthermore, the telescopic movement of the telescopic cylinder's telescopic rod drives a moving plate to adjust the horizontal position of the detection probe. This dual-dimensional adjustment method allows the detection probe to flexibly reach various detection points on the tire surface, improving the comprehensiveness and accuracy of the detection.
