[0020] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention. Rather, the embodiments of the present invention include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0021] The following description, in conjunction with the accompanying drawings, describes a speed measuring device for electric tricycle production according to an embodiment of the present invention.

[0022] like Figures 1-4 As shown, the speed measuring device for electric tricycle production according to this utility model embodiment includes a test plate 1, multiple electric telescopic rods 2, multiple push plates 3, and a speed measuring component 4. The multiple electric telescopic rods 2 are mounted on the test plate 1, and the multiple push plates 3 are respectively mounted on the corresponding electric telescopic rods 2.

[0023] It should be noted that the installation of multiple electric telescopic poles 2 can be carried out as needed, as long as they can support the electric tricycle.

[0024] The speed measuring component 4 includes an adjustment mechanism 41, a rotating rod 42, a rotating disk 43, a wheel speed sensor 44, a telescopic rod 45, a first spring 46, multiple rotating cylinders 47, multiple fixed plates 48, multiple sliding grooves 49, multiple sliding blocks 410, multiple connecting pipes 4101, multiple snap-fit ​​grooves 4102, and multiple positioning mechanisms 5, wherein the adjustment mechanism 41 is mounted on the test plate 1.

[0025] It should be noted that the wheel speed sensor 44 uses existing technology, which is well known to those skilled in the art, and its specific structure and principle will not be described in detail here.

[0026] The rotating rod 42 is rotatably mounted on the adjusting mechanism 41. A rotating disk 43 is mounted on one end of the rotating rod 42, and a wheel speed sensor 44 is mounted on the rotating disk 43. A telescopic rod 45 is slidably mounted inside the rotating rod 42. A first spring 46 is mounted inside the rotating rod 42, and one end of the first spring 46 is connected to one end of the telescopic rod 45.

[0027] It should be noted that after adjusting the position of the telescopic rod 45, it is necessary to ensure that the telescopic rod 45 and the wheel are on the same center.

[0028] Multiple rotating cylinders 47 are arranged in a linear array on the telescopic rod 45, and are rotatably connected to the telescopic rod 45. Multiple fixed plates 48 are respectively installed on the corresponding rotating cylinders 47. Multiple sliding grooves 49 are respectively formed on the corresponding fixed plates 48. Multiple sliding blocks 410 are respectively slidably disposed in the corresponding sliding grooves 49.

[0029] It should be noted that the sliding block 410 and the sliding groove 49 can adjust the position of the connecting pipe 4101. Thus, when facing electric tricycle wheel hubs of different sizes, the sliding block 410 and the sliding groove 49 can be used to slide the connecting pipe 4101, thereby adapting to electric tricycle wheel hubs of different diameters. Furthermore, a rubber pad is provided at the connection between the sliding block 410 and the sliding groove 49. The rubber ring is used to increase the resistance when the sliding block 410 slides, so as to ensure the stability of the sliding block 410 after sliding.

[0030] Multiple connecting pipes 4101 are respectively installed on corresponding sliding blocks 410, and multiple snap-fit ​​grooves 4102 are respectively formed on corresponding connecting pipes 4101. Multiple positioning mechanisms 5 are respectively set on corresponding rotating cylinders 47.

[0031] Specifically, in the actual operation process, relevant personnel need to test the speed of the electric tricycles after production to ensure that the electric tricycles meet the factory requirements.

[0032] When it is necessary to test the speed of the electric tricycle after production, the telescopic rod 45 is first pulled, causing it to retract towards the rotating rod 42. Then, the electric tricycle to be tested is driven onto the test plate 1. The electric telescopic rod 2 then drives the push plate 3 to lift the electric tricycle, so that the wheels of the electric tricycle are no longer in contact with the ground. Then, the position of the connecting pipe 4101 is adjusted using the adjusting mechanism 41, so that multiple connecting pipes 4101 are located on one side of the electric tricycle wheels. Then, the telescopic rod 45 is no longer pulled. At this time, the first spring 46 pushes the telescopic rod 45, which in turn drives the rotating cylinder 47, the fixing plate 48, and the connecting pipe 4101. 101 moves towards the wheel, which in turn moves the locking groove 4102 on the connecting pipe 4101 towards the wheel, connecting the locking groove 4102 with the nut on the vehicle. After the nut is connected to the locking groove 4102, the electric tricycle is started, causing the wheel of the electric tricycle to rotate. This, in turn, causes the nut on the electric tricycle wheel to rotate, which in turn causes the connecting pipe 4101 to rotate. The rotation of the connecting pipe 4101 causes the rotating rod 42 to rotate, which in turn causes the rotating disk 43 to rotate, which in turn causes the wheel speed sensor 44 to rotate. Thus, the rotation speed of the electric tricycle can be tested through the wheel speed sensor 44.

[0033] In one embodiment of this utility model, such as Figure 2 As shown, multiple snap-fit ​​slots 4102 are located on the same plane.

[0034] It should be noted that having multiple snap-fit ​​slots 4102 on the same plane allows multiple snap-fit ​​slots 4102 to connect with the bolt caps on the wheel, and the snap-fit ​​slots 4102 and bolt caps are compatible, thus allowing the snap-fit ​​slots 4102 to snap into the bolt caps.

[0035] In one embodiment of this utility model, such as Figure 1 As shown, the adjustment mechanism 41 includes a threaded plate 411, a first threaded rod 412, a sliding plate 413, a second threaded rod 414, a moving groove 415, and a moving block 416, wherein the threaded plate 411 is mounted on the test plate 1.

[0036] It should be noted that the movable block 416 is limited by the movable groove 415, so that the movable block 416 can only move up and down within the movable groove 415, and cannot rotate.

[0037] A first threaded rod 412 is threaded within a threaded plate 411. A sliding plate 413 is rotatably mounted on one end of the first threaded rod 412 and is slidably connected to the test plate 1. A moving groove 415 is formed within the sliding plate 413. A second threaded rod 414 is threaded onto the sliding plate 413, and one end of the second threaded rod 414 is located within the moving groove 415. A moving block 416 is slidably mounted within the moving groove 415 and is rotatably connected to one end of the second threaded rod 414.

[0038] Specifically, in actual operation, if there is a certain deviation between the stopping position of the electric tricycle and the connecting pipe 4101, the first threaded rod 412 can be rotated. Since the first threaded rod 412 is threadedly connected to the threaded plate 411, rotating the first threaded rod 412 will cause it to move. The movement of the first threaded rod 412 will drive the sliding plate 413 to move, which in turn will drive the connecting pipe 4101 to move laterally. Alternatively, the second threaded rod 414 can be rotated. Since the second threaded rod 414 is threadedly connected to the sliding plate 413, rotating the second threaded rod 414 will cause it to move up and down. The up and down movement of the second threaded rod 414 will drive the moving block 416 to move up and down, which in turn will drive the connecting pipe 4101 to move up and down. The operator can rotate the first threaded rod 412 and the second threaded rod 414 according to the stopping position of the electric tricycle to move the connecting pipe 4101 to one side of the wheel.

[0039] In one embodiment of this utility model, such as Figure 4 As shown, the positioning mechanism 5 includes a positioning rod 51, a positioning disk 52, a second spring 53, and multiple positioning grooves 54, wherein the positioning rod 51 is slidably mounted on the corresponding rotating cylinder 47.

[0040] It should be noted that the rotating cylinder 47 can only rotate on the surface of the telescopic rod 45, and cannot move back and forth on the surface of the telescopic rod 45.

[0041] A positioning disk 52 is mounted on one end of a positioning rod 51. A second spring 53 is sleeved on the positioning rod 51, with one end of the second spring 53 connected to the positioning disk 52 and the other end connected to the rotating cylinder 47. Multiple positioning slots 54 are arranged in a circular array on the rotating cylinder 47.

[0042] Specifically, in actual operation, since the bolt caps of different wheels are at different angles, the position of the connecting pipe 4101 needs to be adjusted according to the different wheels. During adjustment, the positioning plate 52 is pulled first. The movement of the positioning plate 52 will drive the positioning rod 51 to move. The movement of the positioning rod 51 will cause the positioning rod 51 to no longer be engaged with the positioning groove 54, so that the rotating cylinder 47 can be rotated. At the same time, when the positioning plate 52 is pulled, the second spring 53 will be pulled, so that the second spring 53 is in a stretched state. Then, after the rotating cylinder 47 is rotated, the positioning plate 52 can be pulled by the stretched second spring 53, so that the positioning groove 54 is engaged with the positioning rod 51, thus completing the positioning of the rotating cylinder 47 after rotation.

[0043] In summary, the speed measuring device for electric tricycle production according to this utility model embodiment directly connects the connecting pipe 4101 to the wheel by using the telescopic rod 45 to achieve direct measurement of the wheel speed. This method not only improves the accuracy of speed measurement and avoids errors caused by indirect conversion, but also provides instantaneous speed information in real time, ensuring the timeliness and accuracy of speed data.
