[0002] Currently, after production, two-wheeled motorcycles or electric vehicles on the market often require clamping and fixing the entire vehicle for static testing to obtain data such as dimensions. This data is then compared with the original design model to make adjustments. However, most current static testing devices require manual operation of various clamping structures to fix the vehicle, followed by manual measurement and recording of various required data. The manual operation of these devices is cumbersome, labor-intensive, and highly dependent on the worker's skill and experience, making them prone to data distortion due to unstable clamping or measurement errors. Therefore, there is an urgent need for a vehicle clamping device and a static scanning device that can reduce operational steps, lower labor intensity, more accurately position the vehicle, reduce clamping instability, and obtain more accurate static data.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] The purpose of this invention is to provide a vehicle clamping device and a vehicle static scanning device to solve the problems existing in the prior art. These devices can reduce operation steps, reduce labor intensity, more accurately position the vehicle, reduce clamping instability, and obtain more realistic static data.

[0029] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0030] Example 1

[0031] This embodiment provides a vehicle clamping device, such as Figure 1-7 As shown, it includes: a controller, a front wheel clamping mechanism 1 and a rear wheel clamping mechanism 2. The front wheel clamping mechanism 1 and the rear wheel clamping mechanism 2 are arranged sequentially and are both signal-connected to the controller. The front wheel clamping mechanism 1 has multiple movable front clamping parts, and the rear wheel clamping mechanism 2 has multiple movable rear clamping parts. Each front clamping part can move closer or further away from each other under the control of the controller to clamp or release the front wheel 37 of the electric vehicle. Each rear clamping part can move closer or further away from each other under the control of the controller to clamp or release the rear wheel 38 of the electric vehicle.

[0032] The vehicle clamping device provided in this embodiment can clamp various vehicle types such as electric bicycles, bicycles, and two-wheeled motorcycles. Operators can operate the controller to move the front wheel clamping mechanism 1 and the front clamping part closer or further apart to clamp the front wheel 37, and the rear wheel clamping mechanism 2 and the rear clamping part closer or further apart to clamp the rear wheel 38, thus securing the entire vehicle. Afterwards, a scanning device can scan the entire vehicle to obtain various data. Controlling the front wheel clamping mechanism 1 and the rear wheel clamping mechanism 2 with the controller replaces the original manual clamping, reducing manual operation steps and lowering the labor intensity of workers. Furthermore, compared to manual operation, controller control allows for more precise positioning of the vehicle and reduces clamping instability caused by human error, ensuring the vehicle is more stably and reliably clamped on the device. Then, in conjunction with the scanning equipment, more accurate static data can be obtained.

[0033] It should be noted that the number of front clamping parts and rear clamping parts can be set as needed. For example, a front wheel 37 can be provided with four front clamping parts. The four front clamping parts are divided into two groups, with two parts in each group. The two groups of front clamping parts clamp the front wheel 37 from both sides of the front wheel 37 respectively.

[0034] In this embodiment, both the front wheel clamping mechanism 1 and the rear wheel clamping mechanism 2 include: a support unit 7, a drive unit, a first slide rail 4, a second slide rail 5, and two clamping units 6. The first slide rail 4 and the second slide rail 5 are both fixedly connected to the support unit 7 and both extend along a first direction. There is a gap between the first slide rail 4 and the second slide rail 5. The two clamping units 6 are slidably connected to the first slide rail 4 and the second slide rail 5, respectively. The two clamping units 6 of the front wheel clamping mechanism 1 are each provided with a front clamping part, and the two clamping units 6 of the rear clamping part are each provided with a rear clamping part. The drive unit is fixedly connected to the support unit 7 and is transmittedly connected to the two clamping units 6, respectively. The drive unit is signal connected to the controller and can drive the two clamping units 6 to move closer or further apart under the control of the controller. When clamping the front wheel 37 or rear wheel 38 of a vehicle, the front wheel 37 or rear wheel 38 can be positioned between two clamping units 6. Then, under the control of the controller, the two clamping units 6 slide along the first slide rail 4 and the second slide rail 5 respectively. When the two clamping units 6 are close together, they clamp and fix the front wheel 37 or rear wheel 38 of the vehicle; when they are far apart, they release the front wheel 37 or rear wheel 38. A front clamping station is formed between the two front clamping parts. A front wheel limiting member 8 is provided on the support unit 7 on the side of the front clamping station away from the rear wheel clamping mechanism 2. The front wheel limiting member 8 can limit the vehicle in the length direction. Two first slide rails 4 are provided, and the two first slide rails 4 are parallel to each other. Two second slide rails 5 are also provided, and the two second slide rails 5 are parallel to each other.

[0035] In this embodiment, the drive unit includes a motor 9, a transmission box 10, a first lead screw 11, and a second lead screw 12. The motor 9 and the transmission box 10 are both fixedly connected to the support unit 7. The output shaft of the motor 9 is connected to the input end of the transmission box 10. The transmission box 10 has two output ends, which are respectively connected to the first lead screw 11 and the second lead screw 12. The first lead screw 11 and the second lead screw 12 are both parallel to a first direction. Both clamping units 6 include a base 13 and a clamping plate 14. The two bases 13 are slidably connected to the first slide rail. On the 4th and the second slide rail 5, two clamping plates 14 are fixedly connected to two bases 13 respectively. The base 13 has a connecting part 15. The connecting part 15 is provided with screw holes 16 that connect the two sides of the connecting part 15. The axis of the screw holes 16 is parallel to the first direction. The first lead screw 11 and the second lead screw 12 pass through the screw holes 16 of the two connecting parts 15 respectively and are threadedly connected to the screw holes 16. The two clamping plates 14 are arranged opposite to each other in the first direction. The two clamping plates 14 of the front wheel clamping mechanism 1 form two front clamping parts, and the two clamping plates 14 of the rear clamping part form two rear clamping parts. When clamping the front wheel 37 and rear wheel 38 of a vehicle, the front wheel 37 can be positioned between the two clamping plates 14 of the front wheel clamping mechanism 1, and the rear wheel 38 can be positioned between the two clamping plates 14 of the rear wheel clamping mechanism 2. The controller then controls the output shaft of the motor 9 to rotate, and the output shaft of the motor 9 outputs its torque to the transmission box 10. The transmission box 10 distributes the torque to the first lead screw 11 and the second lead screw 12. The first lead screw 11 and the second lead screw 12 form a lead screw-nut structure with the two connecting parts 15, respectively. The rotation of the first lead screw 11 and the second lead screw 12 causes the two connecting parts 15 to move along the extension directions of the first lead screw 11 and the second lead screw 12, thereby driving the two bases 13 to slide along the first slide rail 4 and the second slide rail 5, respectively. This achieves control of the clamping and releasing actions of the front wheel clamping mechanism 1 and the rear wheel clamping mechanism 2 using the controller. Preferably, the motor 9 is a servo motor.

[0036] It should be noted that, in addition to the clamping plate 14, the front clamping part and the rear clamping part can also adopt various shapes such as blocks and claws.

[0037] In this embodiment, the clamping unit 6 further includes a guide member 17 and a bearing 18. The guide member 17 is fixedly connected to the support unit 7 and has a guide through hole coaxially arranged with the screw hole 16. The outer ring of the bearing 18 is fixedly connected to the inner wall of the guide through hole. The first lead screw 11 and the second lead screw 12 pass through the guide through holes on the two guide members 17 respectively, and the outer surfaces of the first lead screw 11 and the second lead screw 12 are fixedly connected to the inner rings of the two bearings 18 respectively. When the first lead screw 11 and the second lead screw 12 rotate, they can drive the inner rings of the bearings 18 to rotate. At this time, the two bearings 18 can respectively guide and limit the first lead screw 11 and the second lead screw 12, improving the stability of the first lead screw 11 and the second lead screw 12 during rotation. In the front wheel clamping mechanism 1 and the rear wheel clamping mechanism 2, there are four guide members 17, namely two first guide members 17 and two second guide members 17. The two first guide members 17 are respectively arranged on both sides of the connecting part 15 connected to the first lead screw 11, and the two second guide members 17 are respectively arranged on both sides of the connecting part 15 connected to the second lead screw 12. The bearings 18 on the four guide members 17 are coaxially arranged.

[0038] In this embodiment, the front wheel clamping mechanism 1 and the rear wheel clamping mechanism 2 further include: a bearing plate 21, an adjusting plate 20, and a planar bearing assembly 22. An adjusting window 19 is provided on the support unit 7, connecting both sides of the support unit 7. The adjusting window 19 is located between the two clamping plates 14. The bearing plate 21 is fixedly connected to the support unit 7 and located below the adjusting window 19. The planar bearing assembly 22 is fixedly connected to the adjusting plate 20. The adjusting plate 20 is disposed on each planar bearing assembly 22 and located within the adjusting window 19. The size of the adjusting plate 20 is smaller than the size of the adjusting window 19. The upper side of the adjusting plate 20 is used to hold the wheel. To improve the scanning accuracy, when the two clamping plates 14 clamp the wheel, the position of the wheel in the first direction needs to be adjusted using the two clamping units 6 so that the wheel is positioned relative to the support unit 7 at a specified position. However, when clamping is not performed using clamping plate 14, the initial position of the wheel may deviate from the designated position. In this case, the wheel needs to be moved relative to the support unit 7. However, electric vehicles or motorcycles are heavy, and the friction between the wheel and the support unit 7 is also large. It is very difficult to move the wheel by relying solely on the motor 9 to drive clamping plate 14. The planar bearing assembly 22 between the adjusting plate 20 and the bearing plate 21 is composed of multiple planar bearing assemblies 22. This allows the adjusting plate 20 to move relative to the bearing plate 21 within the adjusting window 19. When adjusting the wheel position, the wheel can be placed on the adjusting plate 20, and the wheel can be moved by moving clamping plate 14. The friction between the wheel and the adjusting plate 20 is large, and the adjusting plate 20 will also move when the wheel moves. This is more labor-saving than the wheel directly rubbing against the support unit 7.

[0039] In this embodiment, the vehicle clamping device further includes an auxiliary support mechanism 3, which is disposed between the front wheel clamping mechanism 1 and the rear wheel clamping mechanism 2. The auxiliary support mechanism 3 is signal-connected to the controller and has a movable support part 30. The controller can control the movement of the support part 30 to support the bottom of the vehicle. Before clamping the vehicle, the front wheels 37 of the vehicle can be moved between the two front clamping parts, and the rear wheels 38 of the vehicle can be moved between the two rear clamping parts. The controller controls the support part 30 of the auxiliary support mechanism 3 to support the bottom of the vehicle, preventing the vehicle from tilting. The operator can also release the support of the vehicle.

[0040] In this first embodiment, the auxiliary support mechanism 3 includes: an intermediate support structure 23, a cylinder 24, a rack 25, a rotating wheel 26, a gear seat 27, a gear 28, a rotating shaft 29, and a support part 30. The intermediate support structure 23 is disposed between the front wheel clamping mechanism 1 and the rear wheel clamping mechanism 2. The cylinder 24 is fixedly connected to the intermediate support structure 23, and the piston rod of the cylinder 24 is horizontally arranged. The rack 25 is fixedly connected to the piston rod of the cylinder 24, and the rotating wheel 26 rotates around the first rotating shaft. The first rotating shaft is horizontally positioned and perpendicular to the piston rod of the cylinder 24, connected to the intermediate support structure 23. The side of the rack 25 away from the toothed portion contacts the rotating wheel 26. A gear seat 27 is fixedly connected to the intermediate support structure 23, and a gear 28 is rotatably connected to the gear seat 27. The toothed portion of the rack 25 meshes with the gear 28. A rotating shaft 29 is parallel to the first rotating shaft and at least one end is fixedly connected to the gear 28. A support part 30 is fixedly connected to the shaft of the gear 28. The cylinder 24 is signal-connected to the controller. When the auxiliary support mechanism 3 is used for support, the controller controls the cylinder 24 to extend its piston rod, causing the rack 25 to move horizontally. The meshing of the rack 25 with the gear 28 causes the gear 28 to rotate, which in turn causes the rotating shaft 29 to rotate, thus rotating the support part 30 until it contacts the bottom of the vehicle. At this point, the support part 30 can support the bottom of the vehicle. After scanning is completed, the piston rod of the cylinder 24 shortens, and the support part 30 moves away from the bottom of the vehicle, releasing the support. Among them, the preferred adjustment drive component is a servo motor 9.

[0041] In addition, the auxiliary support mechanism 3 also includes: a limiting block 44 and a connecting piece 45. The limiting block 44 is fixedly connected to the intermediate support structure 23. A limiting groove is provided on the limiting block 44, with the groove opening facing upward. When the piston rod of the cylinder 24 retracts, the support part 30 rotates away from the bottom of the vehicle and enters the limiting groove. When the support part 30 contacts the bottom surface of the limiting groove, the limiting groove restricts the rotation of the support part 30, and the support part 30 is located in the preset retraction position, thereby preventing the piston rod of the cylinder 24 from retracting excessively and causing the support part 30 to deviate from the retraction position. The connecting piece 45 is fixedly connected to the piston rod of the cylinder 24, and the rack 25 is fixedly connected to the connecting piece 45. The side of the connecting piece 45 facing away from the rack 25 contacts the rotating wheel 26.

[0042] It should be noted that the connection at the end of the rotating shaft 29 has the following configurations: a cylinder 24, a rack 25, a rotating wheel 26, a gear seat 27, and a gear 28 are provided on one side of the intermediate support structure 23, one end of the rotating shaft 29 is fixedly connected to the gear seat 27, and the other end is rotatably connected to the intermediate support structure 23; and, provided that the gear seat 27 has sufficient support capacity for the rotating rod, a cylinder 24, a rack 25, a rotating wheel 26, a gear seat 27, and a gear 28 are provided on one side of the intermediate support structure 23, one end of the rotating shaft 29 is fixedly connected to the gear seat 27, and the other end is suspended; and, a cylinder 24, a rack 25, a rotating wheel 26, a gear seat 27, and a gear 28 are provided on opposite sides of the intermediate support structure 23 in the same connection manner, and the two ends of the rotating shaft 29 are respectively fixedly connected to the two gear seats 27, so that the rotation of the rotating shaft 29 is driven simultaneously by the synchronous movement of the two cylinders 24.

[0043] In this first embodiment, the support unit 7 of the rear wheel clamping mechanism 2 includes: a first rear support plate 31, a second rear support plate 32, a base 33, and a ramp 34. The first rear support plate 31, the base 33, and the ramp 34 are connected end to end. The end of the ramp 34 closest to the base 33 is higher than the other end. The adjustment window 19 of the rear wheel clamping mechanism 2 is disposed on the first rear support plate 31. The rear wheel clamping mechanism 2 also includes: an adjustment support 39, an adjustment guide rail 40, an adjustment screw 41, an adjustment drive 42, and an adjustment block 43. The adjustment guide rail 40 is fixed on the adjustment support 39, and the extension direction of the adjustment guide rail 40 is perpendicular to the first direction. The adjustment drive component 42 is fixedly connected to the adjustment support 39. One end of the adjustment screw 41 is fixedly connected to the output end of the adjustment drive component 42, and the other end is rotatably connected to the adjustment support 39. The adjustment screw 41 is parallel to the adjustment guide rail 40. The adjustment drive component 42 can drive the adjustment screw 41 to rotate. A threaded hole is provided on the adjustment block 43. The adjustment screw 41 passes through the threaded hole and is threadedly connected to the threaded hole. The second rear support plate 32 is slidably connected to the adjustment guide rail 40. The adjustment block 43 is fixedly connected to the first rear support plate 31. The drive unit of the rear wheel clamping mechanism 2, the first slide rail 4, and the second slide rail 5 are all provided on the second rear support plate 32. Since the distance between the front wheel 37 and the rear wheel 38 varies depending on the vehicle model, the distance between the front clamping part and the rear clamping part needs to be adjusted for different vehicle models. At this time, by adjusting the drive component 42 to control the rotation of the adjusting screw 41, and causing the adjusting block 43 to move along the adjusting screw 41, the second rear support plate 32 can slide along the adjusting guide rail 40, thereby adjusting the distance between the rear wheel clamping mechanism 2 and the front wheel clamping mechanism 1. The slope 34 facilitates pushing the vehicle onto the front wheel clamping mechanism 1 and the rear wheel clamping mechanism 2. Two adjusting guide rails 40 are provided, and the two adjusting guide rails 40 are parallel to each other.

[0044] In this first embodiment, the vehicle clamping device provided further includes a touch control panel 35, which is signal-connected to the controller. Operators can conveniently operate the control panel to control the controller, thereby completing the clamping of the vehicle.

[0045] It should be noted that in this embodiment, the support unit 7 of the front wheel clamping mechanism 1, the support unit 7 of the rear wheel clamping mechanism 2, the intermediate support structure 23 and the bottom of the adjusting support 39 are all provided with support legs 36, which are used to support the ground.

[0046] Example 2

[0047] This embodiment provides a vehicle static scanning device, including: a scanning device and the vehicle clamping device in Embodiment 1. The scanning device is capable of scanning the entire vehicle.

[0048] The vehicle static scanning device provided in this embodiment replaces the original manual clamping by using the vehicle clamping device of Embodiment 1, reducing the number of manual operation steps and the labor intensity of workers. At the same time, compared with manual operation, the controller control method can more accurately position the vehicle and reduce the problem of clamping instability caused by human operation errors, so that the vehicle can be clamped on the clamping device more stably and reliably.
