[0008] Optionally, the first locking arm is in a sheet shape and is mounted on the side of the first gear through bolts; the first locking arm has a hole for the first mounting shaft to pass through.
[0009] Optionally, the first locking arm is located on the left side of the second locking arm; the first guiding edge includes: a first front guiding section extending from the first zero-return groove to the right front, and a first rear guiding section extending from the first zero-return groove to the right rear.
[0010] Optionally, the second guiding edge includes: a second front guiding segment extending from the second zeroing groove towards the left front, and a second rear guiding segment extending from the second zeroing groove towards the left rear.
[0011] Optionally, a flange is provided at the top of the mandrel to connect the testing device or the load plate.
[0012] Optionally, the power source is a linear cylinder, a linear oil cylinder or an electric push rod. One end of the power source is hinged to the first locking arm, and the other end is hinged to the mounting seat.
[0013] This application also provides a floating disk, which has the aforementioned zeroing device.

[0016] The working principle of the present utility model is as follows: The testing device or the load plate can be connected to the mandrel.

[0027] The following disclosure provides many different embodiments or examples for implementing different structures of the present utility model. To simplify the disclosure of the present utility model, components and settings of specific examples are described below. Of course, they are only examples and are not intended to limit the present utility model.
[0028] The following is combined with the attached Figure 1 ~attached Figure 3 to describe in detail the embodiments of the present utility model.
[0029] The embodiment of the present utility model provides a zero return device. The zero return device includes: a first gear 1, a second gear 2 meshing with the first gear 1, a first locking arm 3 fixedly connected to the first gear 1, a second locking arm 4 fixedly connected to the second gear 2, a mandrel 5 located between the first locking arm 3 and the second locking arm 4, and a power source 6 for driving the first locking arm 3 and the first gear 1 to rotate around the axis of the first gear 1. It should be understood that in addition to the linear cylinder, linear oil cylinder or electric push rod described below, the power source 6 may also be a servo motor or a swing cylinder for driving the first gear 1 to rotate. One side of the first locking arm 3 facing the second locking arm 4 has a first zero return groove 7 and a first guiding edge 8 for guiding the mandrel 5 to slide towards the first zero return groove 7. One side of the second locking arm 4 facing the first locking arm 3 has a second zero return groove 9 and a second guiding edge 10 for guiding the mandrel 5 to slide towards the second zero return groove 9. When the first zero return groove 7 cooperates with the second zero return groove 9 to lock the mandrel 5 at the same time, the mandrel 5 is located at the zero return position.
[0030] The following describes the specific implementation of the homing device: The testing device or the carrier plate can be connected to the mandrel 5. By driving the first gear 1 to rotate clockwise by the power source 6, the second gear 2 can be driven to rotate counterclockwise, thereby driving the first locking arm 3 and the second locking arm 4 to approach each other. During the process of the first locking arm 3 and the second locking arm 4 approaching each other, based on the position of the mandrel 5; if the first locking arm 3 contacts the mandrel 5 first, the first guiding edge 8 of the first locking arm 3 will guide the mandrel 5 to slide into the first homing groove 7; if the second locking arm 4 contacts the mandrel 5 first, the second guiding edge 10 of the second locking arm 4 will guide the mandrel 5 to slide into the second homing groove 9; finally, the first homing groove 7 of the first locking arm 3 will cooperate with the second homing groove 9 of the second locking arm 4 to lock the mandrel 5 in the homing position, thereby realizing the homing of the testing device or the carrier plate. Conversely, by driving the first gear 1 to rotate counterclockwise by the power source 6, the second gear 2 can be driven to rotate clockwise, thereby driving the first locking arm 3 and the second locking arm 4 to move away from each other, and then releasing the mandrel 5, so that the testing device or the carrier plate can move and rotate to test the vehicle. The homing device can realize the homing of the mandrel 5 and the testing device or the carrier plate by driving the first gear 1 to rotate clockwise by the power source 6; by driving the first gear 1 to rotate counterclockwise by the power source 6, the locking can be released, so that the testing device or the carrier plate can move or rotate freely to test the vehicle.
[0031] Furthermore, it further includes a mounting base 11; the mounting base 11 is provided with a first mounting shaft and a second mounting shaft extending upward; the first gear 1 is rotatably mounted on the first mounting shaft; the second gear 2 is rotatably mounted on the second mounting shaft. It should be understood that the first gear 1 can be rotatably mounted on the first mounting shaft through a first bearing, and the second gear 2 can be rotatably mounted on the second mounting shaft through a second bearing.
[0032] Furthermore, the first locking arm 3 is in a sheet shape and is mounted on the side of the first gear 1 by bolts; the first locking arm 3 has a hole for the first mounting shaft to pass through. It should be understood that by setting the first locking arm 3 in a sheet shape, the right edge thereof forms the first guiding edge 8, which can reduce the size and weight of the first locking arm 3 while ensuring the strength of the first locking arm 3. The second locking arm 4 can be set in a sheet shape like the first locking arm 3.
[0033] Furthermore, the first locking arm 3 is located on the left side of the second locking arm 4; the first guiding edge 8 includes: a first front guiding section 12 extending right forward from the first homing groove 7 and a first rear guiding section 13 extending right backward from the first homing groove 7.
[0034] Further, the second guide 10 includes: a second front guide section 14 extending from the second zeroing groove 9 towards the left front, and a second rear guide section 15 extending from the second zeroing groove 9 towards the left rear.
[0035] Further, a flange 16 is provided at the top of the mandrel 5 to connect the testing device or the carrier plate.
[0036] Further, the power source 6 is a linear cylinder, a linear oil cylinder or an electric push rod. One end of the power source 6 is hinged to the first locking arm 3, and the other end is hinged to the mounting seat 11. It should be understood that by pushing or pulling the first locking arm 3, the power source 6 can drive the first locking arm 3 and the first gear 1 to rotate clockwise or counterclockwise around the axis of the first gear 1.
[0037] The embodiment of the present invention also provides a floating disc having the aforementioned zeroing device.
[0038] Further, the floating disc further includes: an annular panel 17 and a plurality of universal balls 18 that support the annular panel 17; the universal balls 18 are installed on the mounting seat 11 and are evenly distributed around the zeroing position. It should be understood that the testing device or the carrier plate can be installed on the annular panel 17. In this way, the testing device or the carrier plate can be supported by the universal balls 18; the friction between the annular panel 17 and the universal balls is rolling friction, and the resistance is very small. The testing device or the carrier plate can be moved, rotated or zeroed very easily.
[0039] Further, the mounting seat 11 has a limiting hole 19 for the mandrel 5 to pass through, and the aperture of the limiting hole 19 is larger than the diameter of the mandrel 5; the edge of the limiting hole 19 forms the boundary of the moving range of the mandrel 5. It should be understood that by restricting the moving range of the mandrel 5 through the limiting hole 19, it is possible to prevent the annular panel 17 from slipping out of the supporting range of the universal balls 18 when moving with the testing device or the carrier plate.
[0040] Although the specific embodiments of the present invention have been described above, those skilled in the art should understand that without departing from the principles and essence of the present invention, various changes or modifications can be made to these embodiments, but these changes and modifications all fall within the protection scope of the present invention.
