[0037] In this embodiment, a support platform 5 is installed on the upper surface of the main frame body 1 to facilitate the movement and support of the motorcycle.

[0038] For the front-wheel positioning and clamping mechanism 2, it includes a first frame body 21, a first slide bar 22, first left and right clamping plates 23, and a first driving unit 24. Specifically, there are two first frame bodies 21, arranged left and right, and respectively fixed on the main frame body 1. The first slide bar 22 is horizontally installed on the first frame body 21, and multiple first slide bars 22 can be provided, such as four evenly arranged.

[0039] The first left and right clamping plates 23 are slidably connected to the first slide bar 22 and are connected to the first driving unit 24, and are driven by it to move horizontally. For the first driving unit 24, it is a hydraulic cylinder or an electric cylinder.

[0040] The first left and right clamping plates 23 are respectively the first left clamping plate and the first right clamping plate. The structures of the two are the same, and they are respectively slidably connected to the first slide bar 22 on the left side and the first slide bar 22 on the right side.

[0041] To reduce repeated description, in this embodiment, the specific structure of the first left clamping plate is taken as the main body for description.

[0042] The first left clamping plate includes a first lower part 231 slidably connected to the first slide bar 22 and a first upper part 232 for positioning the front wheel. The first upper part 232 includes a first extension arm 233, and the first lower part 231 includes a mounting groove 234 that cooperates with the first extension arm 233. After the first extension arm 233 is inserted into the mounting groove 234 from top to bottom, the first upper part 232 and the first lower part 231 can move horizontally synchronously.

[0043] As pointed out above, a support platform 5 is installed on the upper surface of the main frame body 1. To adapt to the front-wheel positioning and clamping mechanism 2, in this embodiment, a first through groove 51 for the first extension arm 233 to pass through is opened on the support platform 5, and the horizontal length of the first through groove 51 is sufficient to meet the horizontal movement requirements of the first left and right clamping plates 23. After installation, the first upper part 232 is located above the support platform 5 and cooperates with the front wheel; the first lower part 231 is located below the support platform 5, forming a hidden design.

[0044] For the rear-wheel positioning and clamping mechanism 3, its structure is the same as that of the front-wheel positioning and clamping mechanism 2, and different designs can be made in terms of size and the shape of the clamping plate to be more suitable for the rear wheel.

[0045] Specifically, the rear wheel positioning and clamping mechanism 3 includes a second frame body 31, a second slide bar 32, second left and right clamping plates 33, and a second driving unit 34. Specifically, there are two second frame bodies 31, which are arranged left and right and are respectively fixed on the main frame body 1. The second slide bar 32 is horizontally installed on the second frame body 31, and multiple second slide bars 32 can be provided, such as four second slide bars 32 arranged evenly.

[0046] The second left and right clamping plates 33 are slidably connected to the second slide bar 32 and are connected to the second driving unit 34, and are driven by the second driving unit 34 to move horizontally. For the second driving unit 34, it is a hydraulic cylinder or an electric cylinder.

[0047] The second left and right clamping plates 33 are respectively the second left clamping plate and the second right clamping plate. The structures of the two are the same, and they are respectively slidably connected to the second slide bar 32 on the left side and the second slide bar 32 on the right side.

[0048] To reduce repeated description, in this embodiment, the specific structure of the second left clamping plate is taken as the main body for description.

[0049] The second left clamping plate includes a second lower part 331 slidably connected to the second slide bar 32 and a second upper part 332 for positioning the front wheel. The second upper part 332 includes a second extension arm 333. The second lower part 331 includes a mounting groove 334 that cooperates with the second extension arm 333. After the second extension arm 333 is inserted into the mounting groove 334 from top to bottom, the second upper part 332 and the second lower part 331 can move horizontally synchronously.

[0050] As pointed out above, a support platform 5 is installed on the upper surface of the main frame body 1. To adapt to the rear wheel positioning and clamping mechanism 3, in this embodiment, a second through groove 52 for the second extension arm 333 to pass through is opened on the support platform 5, and the horizontal length of the second through groove 52 is sufficient to meet the horizontal movement requirements of the second left and right clamping plates 33. After installation, the second upper part 332 is located above the support platform 5 and cooperates with the rear wheel; the second lower part 331 is located below the support platform 5, forming a hidden design.

[0051] For the double rear wheel positioning and lifting mechanism 4, it includes left and right positioning frames 41, a third slide bar 42, a lifting platform 43, and a third driving unit 44. Among them, the left and right positioning frames 41 include a left positioning frame and a right positioning frame. The two are arranged left and right and are respectively fixed on the main frame body 1. The third slide bar 42 is longitudinally installed on the left and right positioning frames. The left end of the lifting platform 43 is slidably connected to the third slide bar on the left positioning frame, and the right end of the lifting platform 43 is slidably connected to the third slide bar on the right positioning frame.

[0052] Meanwhile, the lower ends of the left positioning frame and the right positioning frame respectively include horizontally arranged extension strips 45. The tail end of the third driving unit 44 is rotatably connected to the outer end of the extension strip 45. The output end of the third driving unit 44 is rotatably connected to an upper swing arm 46 and a lower swing arm 47. Specifically, a connecting shaft passes through the coincidence point of the upper swing arm 46, the lower swing arm 47 and the output end of the third driving unit 44, so that the three form a rotational mating relationship.

[0053] In this embodiment, the upper end of the upper swing arm 46 is rotatably connected to the end of the lifting platform 43, and the lower end of the lower swing arm 47 is rotatably connected to the corresponding positioning frame or the extension strip 45, that is, the lower swing arm 47 on the left side is rotatably connected to the left positioning frame or the extension strip 45 on the left positioning frame, and the lower swing arm on the right side is rotatably connected to the right positioning frame or the extension strip 45 on the right positioning frame.

[0054] In this embodiment, the third driving unit 44 is a hydraulic cylinder, an electric cylinder or a pneumatic cylinder.

[0055] As one implementation manner, the inner end of the extension strip 45 is rotatably connected to the lower ends of the left and right positioning frames and can be turned downward.

[0056] For the convenience of supporting and positioning the rear wheel of the motorcycle, in this embodiment, a plurality of rollers 6 are respectively installed on the front and rear sides of the main frame body 1 where the lifting platform 43 is located. At the same time, the support platform 5 has a third through groove 53 for the lifting platform 43 to pass through and for the rollers 6 to be exposed.

[0057] In order to perform the optical measurement of the outer contour dimensions of the motorcycle, the motorcycle outer contour dimension measurement platform needs to have a fixed optical measurement three-coordinate system, and the center line of the vehicle to be measured needs to be parallel to the side surface of the motorcycle outer contour dimension measurement platform, that is, parallel to a certain axis of the fixed optical three-coordinate system.

[0058] In order to ensure that the motorcycle to be measured is parallel to a certain side surface of the motorcycle outer contour dimension measurement platform, the following method is adopted:

[0059] 1). Positioning of the two-wheel motorcycle on the platform:

[0060] After the motorcycle is pushed onto the platform, the front wheel of the motorcycle is clamped and positioned through the front wheel positioning and clamping mechanism;

[0061] The rear wheel of the motorcycle is clamped and positioned by using the rear wheel positioning and clamping mechanism;

[0062] At this time, the center line of the two-wheel motorcycle can be ensured to be parallel to the side surface of the motorcycle outer contour dimension measurement platform, that is, ensured to be parallel to a certain axis of the fixed optical three-coordinate system.

[0063] 2). Positioning of the sidecar motorcycle on the platform:

[0064] Since the positioning requirements of a sidecar motorcycle are the same as those of a two-wheel motorcycle, only the front and rear wheels of the main vehicle are considered. That is, the positioning method of this vehicle refers to the positioning method of a two-wheel motorcycle on the platform.

[0065] 3). Positioning of a three-wheel motorcycle on the platform:

[0066] After the three-wheel motorcycle is pushed onto the platform, align the front wheel of the motorcycle with the front and rear positions of the front-wheel positioning and clamping mechanism.

[0067] Adopt a rear-wheel positioning and clamping mechanism to clamp and position the rear wheel of the motorcycle.

[0068] Adopt a front-wheel positioning and clamping mechanism to clamp and position the front wheel. At this time, the center line of the three-wheel motorcycle can be guaranteed to be parallel to the side of the motorcycle outline dimension measurement platform, that is, guaranteed to be parallel to a certain axis of the fixed optical three-coordinate.

[0069] 4). Positioning of a right three-wheeled motorcycle on the platform:

[0070] After the right three-wheeled motorcycle is pushed onto the platform, make the positions of the two rear wheels of the right three-wheeled motorcycle basically located in the middle of the two rows of rollers of the double-rear-wheel positioning and lifting mechanism.

[0071] Lower the lifting platform of the double-rear-wheel positioning and lifting mechanism. At this time, the axes of the two rear wheels of the right three-wheeled motorcycle can be automatically perpendicular to the side of the optical measurement platform, and then fix the rear-wheel brake.

[0072] Align the front wheel, and raise the lifting platform back to the initial position. At this time, the center line of the right three-wheeled motorcycle can be guaranteed to be parallel to the side of the motorcycle outline dimension measurement platform, that is, guaranteed to be parallel to a certain axis of the fixed optical three-coordinate.

[0073] How to ensure that the center line of the motorcycle is parallel to the side of the optical measurement platform after the front-wheel positioning and clamping mechanism and the rear-wheel positioning and clamping mechanism are clamped:

[0074] The front-wheel positioning and clamping mechanism consists of left and right clamping plates, and the left and right clamping plates are respectively driven by left and right hydraulic cylinders / electric cylinders. The left and right hydraulic cylinders / electric cylinders operate synchronously to ensure that the center line of the fixture remains unchanged under any conditions.

[0075] During the clamping process of the left and right clamping plates, one side of the clamping plate may touch the trailer wheel first. At this time, the hydraulic cylinder / electric cylinder on this side will increase the thrust, and the driving force of the driving mechanism of the other clamping plate will maintain the original smaller force; but at this time, the traveling speed and displacement of the left and right clamping plates still remain the same, so that the center line of the left and right clamping plates can be guaranteed to remain unchanged.

[0076] The working principle of the rear-wheel clamping mechanism is the same as that of the front-wheel clamping mechanism. It can also ensure that the center of the left and right clamping plates remains unchanged under any conditions and is consistent with the center line position of the left and right clamping plates of the front wheel.

[0077] Considering that different motorcycles have different wheelbases, in order to adapt to different motorcycles, the rear wheel clamping mechanism is appropriately lengthened.

[0078] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
