[0002] Many maintenance vehicles do not have tire pressure monitoring functions; if a vehicle is driven on the road with insufficient tire pressure and the staff does not notice, it can easily cause a traffic accident. Therefore, tire pressure monitoring for inspection vehicles is particularly important. When checking the tire pressure of a vehicle, it is necessary to position each tire so that the tire pressure can be safely checked based on the contact area between the tire bottom surfaces.

[0003] Currently, the tire alignment devices in existing automotive tire pressure monitoring systems are not ideal for quickly locating the tires to facilitate tire pressure detection via identification cameras.

[0016] This invention provides a tire alignment device in an automotive tire pressure monitoring system, which has the following advantages:

[0017] In this invention, a positioning block automatically positions and moves the identification and detection camera at the outer end of the support arm to the diameter line of the wheel body. Tire pressure is then detected by comparing the tire tread area on the outer edge of the wheel's bottom with a preset normal pressure area. A transmission rod drives the identification and detection camera to perform wheel edge detection, simultaneously detecting tire pressure at the bottom of the wheel and assessing the wear degree of the tire tread along the overall outer edge contour of the wheel, thus improving the device's detection effectiveness. A connecting component allows the left and right single-arm positioning frames to connect and assist in positioning the wheel, further enhancing the device's positioning effect. Furthermore, a moving block, in conjunction with a limiting block, allows the device to adjust the positioning of the moving block according to different wheel sizes, thereby adjusting the distance between the identification and detection camera at the outer end of the support arm and the detection rotating rod axis. This enables the identification and detection camera to perform positioning detection around the detection rotating rod at different shaft diameters, giving the device excellent adjustability.

[0018] Furthermore, the sliding rod at the inner end of the positioning block is slidably installed on the sliding hole of the connecting plate at the rear end of the single-arm positioning frame. Under the action of the first elastic element on the sliding rod, the two sets of positioning blocks are put together. The electric telescopic rod on the bracket drives the single-arm positioning frame on the same side to move from the outside to the inside. In conjunction with the positioning wedge at the inner end of the positioning block, and the racks on the two sets of positioning blocks respectively meshing with the upper and lower ends of the linkage gear on the single-arm positioning frame, the positioning wedge moves outward at the same time when it contacts the wheel body. Under the action of the first elastic element, the two sets of positioning blocks clamp and position the corresponding wheel body. The center line of the single-arm positioning frame at the inner end of the two sets of positioning blocks is parallel to the diameter line of the wheel body in the vertical direction. This allows the identification and detection camera at the outer end of the support arm to automatically position and move to the diameter line of the wheel body. The tire pressure is detected by comparing the tire tread area at the bottom outer edge of the wheel body with the preset normal tire tread area, thus avoiding the problem of insufficient tire pressure causing traffic accidents.

[0019] Furthermore, the first bevel gear on the transmission rod meshes with the second bevel gear on the detection rotating rod, and the second motor drives the detection rotating rod and its identification and detection camera to perform wheel edge detection around the wheel body. This allows for tire pressure detection at the bottom of the wheel body while simultaneously detecting the wear degree of the tire tread on the overall outer edge contour of the wheel body, improving the detection effect of the device and avoiding the problem of severe tire tread wear on the overall outer edge contour of the wheel body affecting vehicle safety. The outer end of the connecting sleeve is fixedly installed on the inner end of the left single-arm positioning frame, and the outer end of the connecting shaft is fixedly installed on the inner end of the right single-arm positioning frame. The connecting shafts are slidably installed on the inner side of the connecting sleeve, so that the left and right single-arm positioning frames play a role in mutual connection and auxiliary positioning when positioning the wheel body, further improving the positioning effect of the device.

[0020] Furthermore, the guide block on the moving block is slidably mounted on the guide groove inside the single-arm positioning frame. The adjusting screw hole on the moving block is threaded onto the adjusting screw of the single-arm positioning frame. Depending on the size of the wheel, the first motor can drive the moving block to move up and down via the adjusting screw. The connecting rod at the outer end of the limiting block is slidably mounted on the sliding hole of the support plate. The inner end of the limiting block has an inclined structure. The limiting arc plate at the inner end of the single-arm positioning frame limits the limiting post on the outer side of the support arm in the up and down direction. When the moving block moves up and down... When in motion, the limiting block moves outward. When the moving block moves to the desired position, under the action of the second elastic element on the connecting rod, the limiting block moves inward, and the limiting block on the detection rotating rod is inserted into the limiting groove of the support arm rod, so that the device can adjust the positioning of the moving block according to the wheel body of different sizes, thereby adjusting the distance between the identification detection camera at the outer end of the support arm rod and the axis of the detection rotating rod, so that the identification detection camera can perform positioning detection around the detection rotating rod with different shaft diameters, giving the device better adjustability.
