[0024] The embodiments of this utility model are described in detail below. Examples of these embodiments 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 are only used to explain this utility model, and should not be construed as limiting this utility model.
[0025] The following is for reference. Figure 1 The present invention describes a vehicle attitude adjustment fixture 10 for zeroing a vehicle steering system according to an embodiment of the present invention. The vehicle attitude adjustment fixture 10 can adjust the overall vehicle attitude along a second direction, the second direction being the vehicle's front-to-back direction.
[0026] Reference Figure 1As shown, the vehicle attitude adjustment fixture 10 for zeroing the vehicle steering system according to an embodiment of the present invention includes: fixture body 1, support mechanism 2 and multiple position adjustment mechanisms 3. Along the first direction, support mechanism 2 is provided on both opposite sides of fixture body 1. The support mechanism 2 is used to support the wheels of the vehicle. Multiple position adjustment mechanisms 3 are provided on fixture body 1 and arranged sequentially at intervals along the second direction. The multiple position adjustment mechanisms 3 are respectively used to cooperate with the corresponding wheels of the vehicle to adjust the overall vehicle attitude along the second direction. The first direction, the second direction and the height direction of vehicle attitude adjustment fixture 10 are perpendicular to each other.
[0027] The vehicle attitude adjustment fixture 10 can complete some of the work before zeroing the vehicle steering system and can be used to adjust the overall vehicle attitude. The fixture body 1 can be constructed as a flat plate structure and can be placed flat on the ground. The fixture body 1 can be used to install and fix other components of the vehicle attitude adjustment fixture 10. Along the first direction, support mechanisms 2 are provided on opposite sides of the fixture body 1. The support mechanisms 2 can abut against the lower surface of the vehicle's wheels to support the vehicle's wheels. Multiple position adjustment mechanisms 3 are provided on the fixture body 1. Along the second direction, multiple position adjustment mechanisms 3 are arranged in sequence at intervals. Multiple position adjustment mechanisms 3 can cooperate with the vehicle's wheels. For example, the vehicle can have a set of front wheels and a set of rear wheels. Multiple position adjustment mechanisms 3 can be used to adjust the front wheels and rear wheels respectively so that the central axis direction of the front wheels and rear wheels is the same as the first direction to adjust the direction of the wheels, thereby adjusting the overall vehicle attitude along the second direction.
[0028] As some embodiments of this utility model, the vehicle attitude adjustment fixture 10 can be used to adjust a four-wheeled vehicle. The four-wheeled vehicle may include a set of front wheels and a set of rear wheels. The vehicle can be moved onto the support mechanism 2 of the vehicle attitude adjustment fixture 10 so that the front wheels are placed on one support mechanism 2 and the rear wheels are placed on another support mechanism 2, so that multiple wheels of the vehicle are supported by multiple support mechanisms 2, and the vehicle is in a stationary state. There can be two position adjustment mechanisms 3, which correspond to the front wheels and the rear wheels respectively. One position adjustment mechanism 3 can be used to adjust the front wheels, and the other position adjustment mechanism 3 can be used to adjust the rear wheels, so that the direction of the wheels can be adjusted by multiple position adjustment mechanisms 3, thereby adjusting the overall vehicle attitude along the second direction, so as to perform the subsequent zeroing operation of the vehicle steering system. The software, configuration, and zeroing operation can all be completed in one step at the electrical inspection station.
[0029] In the above embodiment, by setting multiple position adjustment mechanisms 3, the vehicle's overall posture along the second direction can be adjusted so that the vehicle can perform subsequent steering system zeroing operations. The vehicle posture adjustment fixture 10 has simple adjustment operation and good effect, which can improve the production cycle and thus improve the efficiency of vehicle roll-off.
[0030] In some embodiments of this utility model, such as Figure 1 As shown, the position adjustment mechanism 3 includes a first adjustment part 31 and a second adjustment part 32. Along the first direction, the first adjustment part 31 is located on one side of the tooling body 1, and the second adjustment part 32 is located on the other side of the tooling body 1. Both the first adjustment part 31 and the second adjustment part 32 are movable relative to the tooling body 1 along the first direction. Both the first adjustment part 31 and the second adjustment part 32 are adapted to abut against the corresponding wheels of the vehicle to adjust the overall posture of the vehicle.
[0031] In this configuration, along the first direction, the first adjustment part 31 can be located on one side of the tooling body 1, and the second adjustment part 32 can be located on the other side of the tooling body 1. Both the first adjustment part 31 and the second adjustment part 32 can move relative to the tooling body 1 along the first direction. Both the first adjustment part 31 and the second adjustment part 32 can be constructed as a plate-like structure, a column-like structure, etc. Both the first adjustment part 31 and the second adjustment part 32 can move away from the tooling body 1 and abut against the corresponding wheel. After the first adjustment part 31 and the second adjustment part 32 abut against the corresponding wheel, they can push the corresponding wheel to make the wheel swing, so that the first adjustment part 31 and the second adjustment part 32 abut against the corresponding wheel at multiple positions, so that the central axis direction of the corresponding wheel is the same as the first direction, thereby adjusting the overall posture of the vehicle. For example, a vehicle may have a set of front wheels and a set of rear wheels. The first adjustment part 31 and the second adjustment part 32 of the front position adjustment mechanism 3 can be used to adjust the front wheels. The first adjustment part 31 of the front position adjustment mechanism 3 can be used to adjust the left front wheel, and the second adjustment part 32 of the front position adjustment mechanism 3 can be used to adjust the right front wheel. The first adjustment part 31 and the second adjustment part 32 of the rear position adjustment mechanism 3 can be used to adjust the rear wheels. The first adjustment part 31 of the rear position adjustment mechanism 3 can be used to adjust the left rear wheel, and the second adjustment part 32 of the rear position adjustment mechanism 3 can be used to adjust the right rear wheel. By setting the first adjustment part 31 and the second adjustment part 32, the adjustment operation can be facilitated, the operation difficulty can be reduced, the adjustment effect is better, and the production cycle can be improved.
[0032] In some embodiments of this utility model, when the wheel tilts along the second direction, the first adjustment part 31 and the second adjustment part 32 move away from the tooling body 1. One of the first adjustment part 31 and the second adjustment part 32 will first come into contact with the corresponding wheel. For example, the first adjustment part 31 will first come into contact with the corresponding wheel. The first adjustment part 31 and the second adjustment part 32 continue to move away from the tooling body 1. The first adjustment part 31 can push the corresponding wheel to make the corresponding wheel swing. The first adjustment part 31 can also push the wheel to move away from the tooling body 1 along the first direction, thereby making the vehicle move away from the tooling body 1 along the first direction until the first adjustment part 31 and the second adjustment part 32 are fully in contact with the corresponding wheel. At this time, the first adjustment part 31, the second adjustment part 32, and the vehicle no longer move, and the operation of adjusting the vehicle posture is completed.
[0033] In some embodiments of the present invention, the position adjustment mechanism 3 is configured such that when the first adjustment part 31 moves toward the tooling body 1, the second adjustment part 32 moves synchronously toward the tooling body 1, and is also configured such that when the first adjustment part 31 moves away from the tooling body 1, the second adjustment part 32 moves synchronously away from the tooling body 1.
[0034] The first adjustment part 31 and the second adjustment part 32 can move synchronously relative to the tooling body 1 along the first direction. They can also move at the same speed relative to the tooling body 1 along the first direction. Furthermore, they can move synchronously away from the tooling body 1 along the first direction to contact the corresponding wheels and adjust the overall vehicle posture. Additionally, they can move synchronously towards the tooling body 1 along the first direction to reduce the distance between them and avoid other components or vehicles. By providing synchronously moving first and second adjustment parts 31 and 32, the position adjustment mechanism 3 can synchronously adjust the corresponding wheels and avoid other components or vehicles, improving the efficiency of the adjustment operation, increasing production cycle time, and enhancing the reliability of the vehicle posture adjustment tooling 10.
[0035] In some embodiments of this utility model, such as Figure 1 As shown, along the first direction, the distance between the first adjustment part 31 and the tooling body 1 is L1, and the distance between the second adjustment part 32 and the tooling body 1 is L2, satisfying the relationship: L1 = L2.
[0036] The distance L1 between the first adjustment part 31 and the tooling body 1, and the distance L2 between the second adjustment part 32 and the tooling body 1, satisfy the relationship: L1 = L2. That is, the distance between the first adjustment part 31 and the tooling body 1 is equal to the distance between the second adjustment part 32 and the tooling body 1. In other words, the tooling body 1 has an axis of symmetry along the first direction, the axis of symmetry extends along the second direction, and the vertical plane containing the axis of symmetry is the plane of symmetry. The first adjustment part 31 and the second adjustment part 32 are symmetrical about the plane of symmetry. For example, a vehicle may have two front wheels and two rear wheels. By using L1 = L2, the first adjustment part 31 and the second adjustment part 32 can adjust the two front wheels (or the two rear wheels). When the two front wheels (or the two rear wheels) are adjusted by the first adjustment part 31 and the second adjustment part 32, the adjusted two front wheels (or the two rear wheels) are symmetrical about the plane of symmetry. Then, by using multiple position adjustment mechanisms 3, the entire vehicle is made symmetrical about the plane of symmetry to adjust the overall vehicle attitude along the second direction, so as to facilitate the subsequent zeroing operation of the steering system.
[0037] In some embodiments of this utility model, such as Figure 1 As shown, at least one of the first adjustment part 31 and the second adjustment part 32 has a plate-like structure.
[0038] The first adjustment part 31 can be constructed as a plate, or the second adjustment part 32 can be constructed as a plate, or both the first adjustment part 31 and the second adjustment part 32 can be constructed as plate. When both the first adjustment part 31 and the second adjustment part 32 are constructed as plate, the normal directions of the first adjustment part 31 and the second adjustment part 32 are the same as the first direction. This arrangement facilitates the contact and cooperation between the first adjustment part 31 and the second adjustment part 32 and the corresponding wheel, which helps to increase the contact area between the first adjustment part 31 and the second adjustment part 32 and the corresponding wheel. When the first adjustment part 31 and the second adjustment part 32 are in contact with the corresponding wheel, it is convenient to push the wheel to move and swing, so that the first adjustment part 31 and the second adjustment part 32 are in contact with the wheel at multiple positions, thereby making the central axis direction of the wheel the same as the first direction, so as to adjust the overall vehicle attitude along the second direction, so as to facilitate the subsequent zeroing operation of the steering system.
[0039] In some embodiments of this utility model, such as Figure 1 As shown, the position adjustment mechanism 3 also includes a drive component 33, which is disposed on the tooling body 1. The drive component 33 is connected to both the first adjustment part 31 and the second adjustment part 32. The drive component 33 is used to drive the first adjustment part 31 and the second adjustment part 32 to move relative to the tooling body 1 along a first direction.
[0040] The drive assembly 33 can be constructed as a gear transmission structure, an electric drive structure, a magnetic drive structure, etc. The drive assembly 33 can be disposed on the tooling body 1. The drive assembly 33 can be connected to both the first adjustment part 31 and the second adjustment part 32 to drive the first adjustment part 31 and the second adjustment part 32 to move relative to the tooling body 1 in a first direction. The drive assembly 33 can drive the first adjustment part 31 and the second adjustment part 32 to move away from the tooling body 1 in the first direction so that the first adjustment part 31 and the second adjustment part 32 abut against the corresponding wheels to adjust the overall vehicle posture in a second direction. The drive assembly 33 can drive the first adjustment part 31 and the second adjustment part 32 to move towards the tooling body 1 in the first direction so that the first adjustment part 31 and the second adjustment part 32 avoid the vehicle, so as to move the vehicle to or away from the vehicle posture adjustment tooling 10, thereby enhancing the structural rationality and reliability of the vehicle posture adjustment tooling 10.
[0041] As some embodiments of this utility model, the vehicle can have two front wheels and two rear wheels. After the vehicle is placed in the vehicle attitude adjustment fixture 10, the drive assembly 33 can drive the first adjustment part 31 and the second adjustment part 32 of multiple position adjustment mechanisms 3 to move away from the fixture body 1. One of the position adjustment mechanisms 3 can be used to adjust the two front wheels, and the other position adjustment mechanism 3 can be used to adjust the two rear wheels, so that the structure and function of the vehicle attitude adjustment fixture 10 are reasonable.
[0042] In some embodiments of this utility model, such as Figure 1 As shown, the drive assembly 33 includes: a first drive part 331, a first telescopic rod 332, and a second telescopic rod 333. The first drive part 331 is fixed to the tooling body 1. The first telescopic rod 332 is connected between the first adjustment part 31 and the first drive part 331. The second telescopic rod 333 is connected between the second adjustment part 32 and the first drive part 331. The first drive part 331 is used to drive the first telescopic rod 332 to extend and retract so that the first telescopic rod 332 drives the first adjustment part 31 to move. The first drive part 331 is also used to drive the second telescopic rod 333 to extend and retract so that the second telescopic rod 333 drives the second adjustment part 32 to move.
[0043] The first drive unit 331 can be configured as a drive motor, an electric drive screw, etc. The first drive unit 331 can be fixed to the tooling body 1. The first drive unit 331 can be welded, snap-fitted, or bolted to the tooling body 1. The first telescopic rod 332 and the second telescopic rod 333 can both be configured as cylindrical rods. The first telescopic rod 332 and the second telescopic rod 333 can both extend along the first direction. The first telescopic rod 332 can be connected between the first adjustment unit 31 and the first drive unit 331. The second telescopic rod 333 can be connected between the second adjustment unit 32 and the first drive unit 331. The first drive unit 331 can simultaneously drive the first telescopic rod 332 and the second telescopic rod 333 to move relative to the tooling body 1 along the first direction, so as to correspondingly drive the first adjustment unit 31 and the second adjustment unit 32 to move relative to the tooling body 1 along the first direction, so as to achieve the effect of adjusting the overall vehicle attitude along the second direction or achieving the effect of avoiding other vehicles. Furthermore, by setting the first drive unit 331, the driving force on the first telescopic rod 332 and the second telescopic rod 333 can be the same and synchronized, so that the first telescopic rod 332 and the second telescopic rod 333 can drive the corresponding first adjustment unit 31 and the second adjustment unit 32 to move relative to the tooling body 1 synchronously and at the same speed, thereby improving the overall vehicle attitude adjustment efficiency.
[0044] As some embodiments of this utility model, there can be multiple first telescopic rods 332 and second telescopic rods 333. The number of first telescopic rods 332 and second telescopic rods 333 can be two, three, four, etc. Multiple first telescopic rods 332 are parallel to each other, and multiple second telescopic rods 333 are parallel to each other to enhance the structural strength of the drive assembly 33, ensure the adjustment effect, improve the reliability of the vehicle attitude adjustment fixture 10, and make the first telescopic rods 332 and second telescopic rods 333 move more smoothly, thereby improving the stability of the drive assembly 33.
[0045] As some embodiments of this utility model, each position adjustment mechanism 3 may have a first driving part 331, for example, such as Figure 1 As shown, the vehicle attitude adjustment fixture 10 is provided with two position adjustment mechanisms 3 arranged at intervals along the second direction. Each position adjustment mechanism 3 includes a first drive unit 331. Each first drive unit 331 can drive the corresponding position adjustment mechanism 3 to move along the first direction to adjust the overall vehicle attitude along the second direction. Furthermore, the two first drive units 331 can be turned on or off simultaneously to drive the corresponding position adjustment mechanism 3 at the same time. This arrangement can increase the driving force on the position adjustment mechanism 3 and improve the work efficiency of the adjustment operation.
[0046] In some embodiments of this utility model, such as Figure 1As shown, the support mechanism 2 includes a mounting base 21 and multiple rollers 22. The multiple rollers 22 are arranged sequentially along the second direction and are rotatably mounted on the mounting base 21. The rotation axis of each roller 22 extends along the first direction. The rollers 22 are used to support the corresponding wheels of the vehicle.
[0047] The mounting base 21 can be welded, snap-fitted, or bolted to the tooling body 1. The multiple rollers 22 can be constructed as cylindrical structures. The multiple rollers 22 can be arranged sequentially along the second direction. The rotation axis of each roller 22 extends along the first direction. The multiple rollers 22 can be rotatably mounted on the mounting base 21. The multiple rollers 22 can rotate relative to the mounting base 21 around their own axes. The rollers 22 can be used to support the corresponding wheels of the vehicle. There can be four support mechanisms 2 along the first direction. Two support mechanisms 2 are located on one side of the tooling body 1 and are spaced apart along the second direction. The other two support mechanisms 2 are located on the other side of the tooling body 1 and are spaced apart along the second direction. The vehicle can have two front wheels and two rear wheels. When the vehicle moves to the vehicle attitude adjustment tooling 10, the four wheels of the vehicle can be placed on the four support mechanisms 2 respectively. The vehicle can be put in neutral. The roller 22 can rotate around its own central axis to drive the corresponding wheel to rotate around the central axis of the wheel. The wheel rotates in place to eliminate the stress between the wheel and the roller 22. When multiple wheels of the vehicle are rotating, the adjustment operation can be performed to ensure the overall vehicle attitude.
[0048] In some embodiments of this utility model, such as Figure 1 As shown, the support mechanism 2 also includes a second drive unit, which is connected to multiple rollers 22 in a transmission manner to drive the multiple rollers 22 to rotate.
[0049] The second drive unit can be configured as a drive motor, an electric drive screw, etc. The second drive unit can be connected to multiple rollers 22 to drive them to rotate, thereby causing the corresponding wheels to rotate around their axes to eliminate stress between the wheels and rollers 22. By setting up the second drive unit, multiple rollers 22 can rotate simultaneously around their own axes to simultaneously eliminate stress between the corresponding wheels and rollers 22, thus improving the efficiency of this step and increasing the production cycle time.
[0050] In some embodiments of this utility model, each roller 22 is movable relative to the mounting base 21 along a first direction.
[0051] Each roller 22 can move relative to the mounting base 21 in the first direction. When the first adjustment part 31 and the second adjustment part 32 come into contact with the corresponding wheel and push the corresponding wheel to move, there is friction between the roller 22 and the wheel. When the position adjustment mechanism 3 pushes the wheel to move relative to the tooling body 1 in the first direction, it can drive the support mechanism 2 to move relative to the tooling body 1 in the first direction. This arrangement makes it easier for the vehicle to move relative to the vehicle posture adjustment tooling 10 in the first direction to adjust the overall vehicle posture in the second direction, so as to facilitate the subsequent zeroing operation of the steering system.
[0052] In some embodiments of this utility model, the vehicle posture adjustment fixture 10 further includes a detection mechanism, which is used to detect the interval distance between the first adjustment part 31 and the fixture body 1 and the interval distance between the second adjustment part 32 and the fixture body 1.
[0053] The detection mechanism can be configured as a displacement sensor, such as an ultrasonic ranging sensor or an infrared ranging sensor. The detection mechanism can detect the distance L1 between the first adjustment part 31 and the tooling body 1, and the distance L2 between the second adjustment part 32 and the tooling body 1. The width of the tooling body 1 along the first direction is L3, and the distance between the wheel tracks of the vehicle is L0. Before the vehicle moves to the vehicle attitude adjustment tooling 10, the detection mechanism can detect the magnitudes of L1 and L2 and transmit the data of L1 and L2 to the controller. The controller can calculate the value of L1 + L2 + L3 and compare the magnitude of L1 + L2 + L3 with L0. If L1 + L2 + L3 < L0, the controller can output information through the display device so that the operator can know that L1 and L2 meet the requirements of the adjustment process. If L0 ≥ L1 + L2 + L3, the controller can control the first drive unit 331 to drive the first telescopic rod 332 and the second telescopic rod 333 to move towards the tooling body 1 to reduce the value of L1 + L2 + L3 until L1 + L2 + L3 < L0. At this time, the controller controls the first drive unit 331 to stop working, and the controller can output information through the display device so that the operator can know that L1 and L2 meet the requirements of the adjustment process so as to proceed with subsequent processes. This setting can avoid interference between the vehicle and the position adjustment mechanism 3, so that the adjustment operation can be carried out smoothly, avoid damage to the position adjustment mechanism 3, improve the reliability of the vehicle attitude adjustment tooling 10, and make the vehicle attitude adjustment tooling 10 adaptable to the wheelbase of different vehicles, thus improving the versatility of the vehicle attitude adjustment tooling 10.
[0054] As some embodiments of this utility model, there can be two position adjustment mechanisms 3 and four detection mechanisms. Two detection mechanisms can be correspondingly arranged with the first adjustment part 31 and the second adjustment part 32 of the front position adjustment mechanism 3 and can measure the distance between the first adjustment part 31 and the second adjustment part 32 of the front position adjustment mechanism 3 and the tooling body 1. The other two detection mechanisms can be correspondingly arranged with the first adjustment part 31 and the second adjustment part 32 of the rear position adjustment mechanism 3 and can measure the distance between the first adjustment part 31 and the second adjustment part 32 of the rear position adjustment mechanism 3 and the tooling body 1, so as to form a four-way position detection mechanism, which can improve detection efficiency.
[0055] As some embodiments of this utility model, the vehicle posture adjustment fixture 10 of this utility model embodiment can perform vehicle posture adjustment operations on a four-wheeled vehicle. Before adjusting the vehicle posture using the vehicle posture adjustment fixture 10 of this utility model embodiment, the sizes of L1 and L2 are first detected by a detection mechanism. The controller can adjust the sizes of L1 and L2 according to the size of L0 of the four-wheeled vehicle, so that L0 > L1 + L2 + L3. Then, the vehicle can be moved onto the support mechanism 2 of the vehicle posture adjustment fixture 10, so that the front wheels are placed on the corresponding support mechanism 2 and the rear wheels are placed on the corresponding support mechanism 2, so that multiple wheels of the vehicle are supported by multiple support mechanisms 2, and the vehicle... When stationary, the vehicle can be in neutral, and the roller 22 can rotate around its own central axis to drive the corresponding wheels to rotate around the central axis of the wheels. Then, the two drive components 33 synchronously drive the first adjustment part 31 and the second adjustment part 32 of the two position adjustment mechanisms 3 to move away from the tooling body 1 in the first direction until the first adjustment part 31 and the second adjustment part 32 of the two position adjustment mechanisms 3 are in contact with the corresponding wheels at multiple positions to adjust the posture of the four wheels until the central axis direction of the four wheels is the same as the first direction. Then the operation of adjusting the overall posture of the vehicle in the second direction is completed, and the subsequent zeroing operation of the vehicle steering system can be carried out.
