[0002] The car wheel is one of the most important parts of the car, responsible for supporting the weight of the vehicle, transmitting power, providing suspension support and ensuring driving safety. The car wheel contacts the ground, enabling the vehicle to move forward, turn and stop, and absorbs road vibrations during driving, providing a comfortable ride experience.

[0003] During normal driving, the tires of cars may be inadvertently punctured by pointed objects such as nails and broken glass scattered on the road. At this time, it is necessary to detect the puncture points on the wheels. However, when inspecting car wheels, most of them are manually searched. When encountering some smaller nails or broken glass, it is difficult to distinguish them with the naked eye, which is inconvenient. Utility Model Content

[0008] Furthermore, the detection mechanism includes a detection sensor and a slider, the slider is sleeved and threadedly connected to the outside of the screw rod, and the outer wall of the slider is slidably connected to the inner wall of the sliding cavity, the bottom surface of the slider is fixedly connected to the upper surface of the detection sensor, and the detection sensor is located directly above the rolling cavity.

[0009] Furthermore, the rolling mechanism includes a rotating motor and a transmission roller. The outer wall of the rotating motor is fixedly connected to the side of the support block away from the bottom plate. The output shaft of the rotating motor passes through the support block and is fixedly connected to one end of the transmission roller. The transmission roller is located on one side above the rolling cavity.

[0010] Furthermore, an anti-slip sleeve is sleeved and fixedly connected to the outer wall of the driving roller.

[0011] Furthermore, the inner wall of the rolling cavity is rotatably connected to two rollers, and the two rollers are respectively located on both sides of the rolling cavity.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] This wheel nail detection positioning device adds a bottom plate, a support frame, a support block and a mobile frame, and sets a moving mechanism and a detection mechanism inside the mobile frame, and sets a rolling mechanism on one side of the support block.

[0017] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0019] like Figure 1 to Figure 2 As shown, when the wheel nail detection positioning device of the utility model is used, the nailed tire is first placed in the rolling chamber 101, and the rolling mechanism is placed on the surface of the tire to be inspected. Then, the rolling mechanism, the moving mechanism and the detection mechanism are simultaneously turned on by an external controller. After the rolling mechanism is started, the tire to be inspected will be driven to rotate in the rolling chamber 101; after the detection mechanism is started, the surface of the tire to be inspected below will be detected (the detection mechanism is a range detection, which can perform a large-scale detection on a certain area directly below. Any existing sensor on the market that can achieve the above purpose can be used here, and the specific type The number is not limited), when the detection mechanism detects the leaking point of the tire or metal nails, glass fragments, etc., it will transmit the electrical signal to the external processor, and then the external controller will control the rolling mechanism to reverse, so that the leaking point of the inspected tire can be rotated to the specified position again (for example, upward or to one side), and then the controller controls the detection mechanism to move to the top of the nail through the moving mechanism (a red dot laser pen or lighting can be set below the detection mechanism to locate the specific position, which is not limited), at this time, the maintenance personnel can quickly find the nail position, which is convenient for tire repair or other maintenance. Finally, it should be specially noted that the above descriptions in brackets and external processors, external controllers, etc. are all very mature existing technologies, so they are not described in detail.

[0020] Please refer to Figure 1 and Figure 2 The upper surface of the moving frame 4 is provided with a sliding cavity 401, and the moving mechanism and the detection mechanism are both located inside the sliding cavity 401. By providing the sliding cavity 401, firstly, the moving mechanism and the detection mechanism can be stored; secondly, the moving tracks of the moving mechanism and the detection mechanism can be limited.

[0021] Please refer to Figure 1 and Figure 2 The moving mechanism includes a moving motor 6 and a screw rod 11. The outer wall of the moving motor 6 is fixedly connected to the side of the support frame 3 away from the base plate 1. The output shaft of the moving motor 6 is fixedly connected to one end of the screw rod 11. The other end of the screw rod 11 passes through the support frame 3, the detection mechanism and the sliding cavity 401, and is rotatably connected to the inner walls of the support frame 3 and the sliding cavity 401.

[0022] More specifically, when it is necessary to control the movement of the detection mechanism, it is only necessary to turn on the switch of the moving motor 6 through an external controller. After the moving motor 6 is started, the output shaft drives the screw rod 11 to rotate, and then the detection mechanism can be driven to move in the sliding cavity 401 through the rotation of the screw rod 11.

[0023] Please refer to Figure 1 and Figure 2 The detection mechanism includes a detection sensor 5 and a slider 10. The slider 10 is sleeved and threadedly connected to the outside of the screw rod 11, and the outer wall of the slider 10 is slidably connected to the inner wall of the sliding cavity 401. The bottom surface of the slider 10 is fixedly connected to the upper surface of the detection sensor 5. The detection sensor 5 is located directly above the rolling cavity 101.

[0024] More specifically, when the detection mechanism needs to be aligned with the surface nailing position of the tire to be inspected below, the screw rod 11 rotates, driving the slider 10 to rotate, and then the slider 10 can be controlled to move in the slide cavity 401, thereby driving the detection sensor 5 to move. It should be particularly noted here that a red dot laser pen or the like can be set on one side of the detection sensor 5 for indication, and some detection sensors 5 have lighting or indication functions themselves, which can be directly irradiated at the nailing position for indication, and there is no specific limitation.

[0025] Please refer to Figure 1 and Figure 2 The rolling mechanism includes a rotating motor 8 and a transmission roller 9. The outer wall of the rotating motor 8 is fixedly connected to the side of the support block 7 away from the bottom plate 1. The output shaft of the rotating motor 8 passes through the support block 7 and is fixedly connected to one end of the transmission roller 9. The transmission roller 9 is located on one side above the rolling cavity 101.

[0026] More specifically, when it is necessary to drive the inspected tire to rotate, the rotating motor 8 is turned on by an external controller. After the rotating motor 8 is started, the transmission roller 9 is driven to rotate, thereby driving the inspected tire against the surface to rotate.

[0027] Please refer to Figure 1 and Figure 2 The outer wall of the driving roller 9 is sleeved and fixedly connected with an anti-skid sleeve. The anti-skid sleeve can increase the friction between the driving roller 9 and the tire to be inspected and reduce the slip rate.

[0028] Please refer to Figure 1 and Figure 2 The inner wall of the rolling cavity 101 is rotatably connected to two rollers 2, and the two rollers 2 are respectively located on both sides of the rolling cavity 101. By providing the rollers 2, the friction force of the tire being tested in the rolling cavity 101 can be reduced.
