Detailed Description
As a specific embodiment of the present invention, as shown in fig. 1 to 4, the present embodiment provides a tire testing device 100 for testing the position and number of joints at a tire. Specifically, the tire testing device 100 may include a fixed platform 10, a pressure sensing device 20, and a telescoping securing mechanism 30. Wherein the pressure sensing device 20 is arranged on the fixed platform 10. A telescoping securing mechanism 30 is coupled to the tire and presses the tire against the pressure sensing device 20 such that the pressure sensing device 20 detects the pressure across the tire against the pressure sensing device 20.
Specifically, a general tire includes rubber and cords, and a joint position exists between different cords, and deformation of the joint position is smaller than that of other regions because the thickness of the cords is larger than that of other positions in the longitudinal direction. Since the tire has different strengths at the joint position and the non-joint position, the deformation at the joint position and the non-joint position is different when the tire is inflated, and therefore, when the tire is pressed against the pressure sensing device 20 after the tire is inflated, the pressure applied to the pressure sensing device 20 is different at the joint position due to the different deformation at the non-joint position, and thus, the position and the number of joints can be recognized.
The tire checking device 100 of the present embodiment includes only the fixed platform 10, the pressure sensing device 20, and the retractable fixing mechanism 30, and the tire is pressed at the pressure sensing device 20 by the retractable fixing mechanism 30, and the position and the number of the joints can be displayed by the pressure applied at the pressure sensing device 20, thereby detecting the approximate position and the number of the joints existing in the tire. The tire detection device 100 of the embodiment has the advantages of simple structure, convenience and rapidness in detection and capability of greatly reducing the detection cost of the tire.
As a specific embodiment of the present invention, the pressure sensing device 20 of the present embodiment is a plate-shaped structure formed by arranging a plurality of micro pressure sensors.
Specifically, the pressure sensing device 20 of the present embodiment is formed by arranging a plurality of micro pressure sensors to form an array, and the array is formed in a plate-like structure. Since the plurality of miniature pressure sensors can detect the pressure applied at the corresponding positions, the pressure applied to the pressure sensing device 20 at different places can be detected when the tire presses on the pressure sensing device 20.
As a specific embodiment of the present invention, the pressure sensing device 20 of the present embodiment has a ring structure. Since the pressure sensing device 20 in this embodiment is for detecting the pressure of the tire, designing it in a shape that is compatible with the tire structure can reduce the area of the pressure sensing device 20, thereby reducing the cost.
As a specific example, the pressure sensing device 20 of the present embodiment has a circular ring structure. The inner diameter of the pressure sensing device 20 with the circular ring structure is smaller than the inner diameter of the tire, and the outer diameter of the pressure sensing device 20 with the circular ring structure is larger than the outer diameter of the tire.
In the present embodiment, on one hand, designing the pressure sensing device 20 as a circular ring structure can reduce the area of the pressure sensing device 20 while satisfying the requirement of detecting the pressure of the tire, thereby reducing the cost, and on the other hand, in order to ensure that the pressures of different tires or different positions of the same tire are all detected by the pressure sensing device 20, the present embodiment configures the pressure sensing device 20 as a circular ring structure, and the inner diameter of the ring is smaller than the inner diameter of the tire, and the outer diameter of the ring is larger than the outer diameter of the tire.
As a specific embodiment of the present invention, a through hole 11 is formed at the fixed platform 10 of this embodiment, and the center of the pressure sensing device 20 is disposed corresponding to the through hole 11. In this embodiment, a through hole 11 is also provided at the fixed platform, and the through hole 11 is adapted to the position of the middle hole of the pressure sensing device 20.
Specifically, the through hole 11 of the present embodiment is square. Specifically, the shape of the through hole 11 may be a square or other shape.
As a specific example, as shown in fig. 1, the fixed platform 10 of the present embodiment may include a platen 12 and at least three support rods 13. The bedplate 12 is fixedly connected with the electric telescopic rod 31 and the pressure sensing device 20. At least three support bars 13 are connected to the bedplate 12 for supporting the bedplate 12. The bedplate 12 is in a square plate shape with the through hole 11 in the middle, the number of the support rods 13 is four, and the four support rods 13 are respectively arranged at four corners of the bedplate 12.
Specifically, the structure of the bedplate 12 may be a circle or other shapes, and the shape and number of the supporting rods 13 may be designed according to practical situations, and are not limited by the embodiment.
As a specific embodiment of the present invention, as shown in fig. 3 and 4, the telescopic fixing mechanism 30 of the present embodiment may include an electric telescopic rod 31 and a fixing flange 32 connected to the electric telescopic rod 31. The electric telescopic rod 31 is connected with the fixed platform 10, and the electric telescopic rod 31 passes through the through hole 11 and the center of the pressure sensing device 20 and protrudes upwards from the pressure sensing device 20. The fixed flange 32 is fixedly connected with the tire, and the electric telescopic rod 31 drives the fixed flange 32 and the tire to move up and down, so that the tire is contacted with or separated from the pressure sensing device 20.
The electric telescopic rod 31 of the present embodiment is disposed at the middle through hole 11 of the fixed platform 10 and can move up and down. The fixing flange 32 can be fixedly connected with the tire, so that the electric telescopic rod 31 can drive the tire to move up and down. Stopping when the tire moves up and down until the side of the tire contacts the pressure sensing device 20 and applies a certain pressure, the position and number of joints inside the tire can be obtained by reading the value of the pressure on the pressure sensing device 20.
Thus, it should be appreciated by those skilled in the art that while a number of exemplary embodiments of the utility model have been illustrated and described in detail herein, many other variations or modifications consistent with the principles of the utility model may be directly determined or derived from the disclosure of the present invention without departing from the spirit and scope of the utility model. Accordingly, the scope of the utility model should be understood and interpreted to cover all such other variations or modifications.
