[0037] Specifically, the present application places the mounting base 10 on the vehicle body 40 to be tested (including the traveling vehicle referred to in the background technology), and makes the gear 20 mesh with the rack 50 on the guide rail, so that when the vehicle body 40 to be tested moves, the gear walking detection device moves with the vehicle body 40 to be tested, and the gear 20 can rotate under the action of the rack 50; the present application counts the number of times the gear 20 and the rack 50 are meshed through the encoder 30, and the data of the encoder 30 is output through the signal output terminal 320, and the walking distance is obtained by processing the data, thereby realizing the detection of the walking distance of the vehicle body 40 to be tested.

[0038] It should be noted that the data collection and processing of the encoder 30 can be carried out using conventional technical means of those skilled in the art, and this application does not impose any restrictions on this.

[0039] In one embodiment, the input end 310 of the encoder 30 is provided with a rotating shaft 311, and the rotating shaft 311 is connected to the gear 20; the mounting seat 10 is provided with a bearing 111, and the bearing 111 is sleeved on the rotating shaft 311. In this embodiment, the input end 310 of the encoder 30 is connected to the gear 20 through the rotating shaft 311, so that when the gear 20 rotates, the rotating shaft 311 can rotate accordingly, so that the encoder 30 can count the number of times the gear 20 and the rack 50 are meshed; and the mounting seat 10 is provided with a bearing 111, so that the rotating shaft 311 can rotate in the bearing 111.

[0040] In one embodiment, the mounting seat 10 includes: a spring seat 110, which is connected to the measured vehicle body 40, and the spring seat 110 is provided with a accommodating cavity 1101; a gear 20 mounting seat 120, which is used to install the gear 20 and the encoder 30; the gear 20 mounting seat 120 is provided with a movable part 1201, and the movable part 1201 is movably arranged in the accommodating cavity 1101, and slides along the length direction of the accommodating cavity 1101 under the action of external force, so that the gear 20 is engaged with the rack 50. In this embodiment, the spring seat 110 is connected and fixed to the vehicle body 40 to be tested, so that the mounting seat 10 as a whole can move together with the vehicle body 40 to be tested; when the vehicle body 40 to be tested moves, due to the fact that the rack 50 has a certain up and down deviation, the gear 20 will also produce an up and down deviation when it rotates under the action of the rack 50. In order to improve the stability of the present application, the movable part 1201 of the gear 20 mounting seat 120 is inserted into the accommodating cavity 1101, so that the movable part 1201 can slide along the length direction of the accommodating cavity 1101 under the action of an external force (i.e., the upward force applied to the gear 20 by the rack 50, or the weight of the gear 20 mounting seat 120 itself, or the elastic force provided by the elastic component 130 described below), so as to achieve full engagement between the gear 20 and the rack 50 and improve the detection stability.

[0041] In one embodiment, the mounting seat 10 further includes: an elastic component 130, which is restricted in the accommodating cavity by the movable portion 1201; the elastic deformation direction of the elastic component 130 is the same as the sliding direction of the movable portion 1201. In this embodiment, the gear 20 is deflected upward under the action of the rack 50, and the movable portion 1201 of the gear 20 mounting seat 120 will move upward in the accommodating cavity 1101, exerting pressure on the elastic component 130, and the elastic component 130 will also feedback a downward elastic force to the movable portion 1201, so that the gear 20 can fully mesh with the rack 50. Similarly, when the rack 50 has a downward deviation, the elastic component 130 will feedback a downward elastic force to the movable portion 1201, so that the gear 20 is deflected downward, so that the gear 20 can fully mesh with the rack 50.

[0042] Regarding the structure of the elastic component 130, in one embodiment, the spring seat 110 is provided with a through hole, and the through hole is connected to the accommodating cavity; the elastic component 130 includes a spring rod 1302 and a spring 1301 sleeved on the spring rod 1302, and one end of the spring rod 1302 is passed through the through hole and connected to the movable part 1201. In this embodiment, the lower end of the spring rod 1302 is provided with an external thread, and the upper part of the movable part 1201 is provided with a threaded hole matching the spring rod 1302. The lower end of the spring rod 1302 is passed through the through hole and fixed to the threaded hole by threaded connection. The spring 1301 is sleeved on the middle and lower part of the spring rod 1302 and is located in the accommodating cavity; one end of the spring 1301 is against the movable part 1201, and the other end of the spring 1301 is against the inner wall of the accommodating cavity 1101, providing elastic force for the movable part 1201, and utilizing the spring rod 1302 to complete the guiding function and prevent displacement.

[0043] Regarding the structure of the elastic component 130, in another embodiment, the elastic component 130 includes a spring 1301, one end of the spring 1301 abuts against the movable part 1201, and the other end of the spring 1301 abuts against the inner wall of the accommodating cavity 1101. In this embodiment, the spring 1301 is directly installed in the accommodating cavity to provide elastic force for the movable part 1201.

[0044] In one embodiment, the spring seat 110 is provided with a guide groove 1102 and a guide rod 1103 that slides along the groove direction of the guide groove 1102, and the guide rod 1103 is connected to the movable part 1201; the groove direction of the guide groove 1102 is the same as the length direction of the accommodating cavity 1101. In this embodiment, the groove direction of the guide groove 1102 is used to limit the sliding direction of the guide rod 1103, thereby controlling the sliding direction of the movable part 1201 and preventing the movable part 1201 from shifting left and right, so as to improve stability. Furthermore, the guide rod is connected and fixed to the movable part 1201 by a threaded connection.

[0045] In one embodiment, the spring seat 110 is connected and fixed to the vehicle body 40 to be tested via a fixing frame 140. In this embodiment, the spring seat 110 is connected to the fixing frame 140 via bolts, the fixing frame 140 is used to increase the installation position of the spring seat 110, and then the fixing frame 140 is connected and fixed to the vehicle body 40 to be tested via bolts.

[0046] In one embodiment, the gear 20 mounting seat 120 includes a first mounting portion 121 and a second mounting portion 122, wherein the first mounting portion 121 is used to mount the gear 20 and the encoder 30; the second mounting portion 122 is located above the gear 20 and is connected to the first mounting portion 121, so that the second mounting portion 122 can be used to shield the gear 20 to prevent foreign objects from above the gear 20 from falling directly onto the gear 20.

[0047] In one embodiment, the spring seat 110 is arranged above or below the gear 20 mounting seat 120. In this embodiment, the positions of the spring seat 110 and the gear 20 mounting seat 120 need to be determined according to the positional relationship between the rack 50 and the gear 20. Specifically, the rack 50 is located below the gear 20, and the spring seat 110 is arranged above the gear 20 mounting seat 120. When the gear 20 is displaced upward under the action of the rack 50, the movable portion 1201 of the gear 20 mounting seat 120 will move upward in the accommodating cavity 1101, pressurizing the elastic component 130, and the elastic component 130 will also feedback a downward elastic force to the movable portion 1201, so that the gear 20 can fully mesh with the rack 50.
