Description

Technical Field

[0001] This utility model relates to the field of steering wheel testing technology, specifically to a steering wheel robot fixture for K&C testing. Background Technology

[0002] K&C testing is an important means of evaluating and optimizing vehicle suspension systems. Its full name is Kinematics and Compliance, which helps improve the overall performance of a vehicle by simulating real-world operating conditions.

[0003] In existing technologies, steering wheel robots are required to simulate drivers during K&C testing. However, due to the different widths of different car models, traditional brackets for fixing steering wheel robots are difficult to quickly adapt to different car models, resulting in low testing efficiency and the risk of unstable fixing, which affects the test results. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention proposes a steering wheel robot fixture for K&C testing, which can be quickly adapted to testing different vehicle models.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a steering wheel robot tooling for K&C testing, comprising a mounting base, a rotating moving base, and a clamp; The mounting base is used to mount the steering wheel robot; The rotating movable seat includes a fixed frame and a sleeve, the mounting seat is disposed on the fixed frame, and the sleeve is disposed on one side of the fixed frame; Two clamps are provided symmetrically, and both can be clamped on the car door. One of the clamps is equipped with a slide rod, and the sleeve is slidably sleeved on the slide rod. The sleeve is equipped with a clamp. The other clamp is fixedly connected to the other side of the fixing frame.

[0006] The steering wheel robot for testing is installed on the mounting base. The sleeve is then slid and rotated on the slide bar to adjust the relative distance between the two clamps and the orientation of the steering wheel robot. After adjustment, the sleeve and slide bar are fixed with clamps so that the two clamps can be clamped onto the left and right doors of the vehicle. The steering wheel robot can then perform simulated steering wheel operations to begin vehicle testing.

[0007] The beneficial effect of the aforementioned steering wheel robot fixture for K&C testing is that the distance between the two clamps can be quickly adjusted by sliding the slide bar and sleeve, thus making it suitable for testing vehicles of different widths.

[0008] Furthermore, the mounting base includes a base plate, upright plates, and mounting plates. The base plate is mounted on a fixed frame, and the two upright plates are fixedly mounted on the base plate, each having an arc-shaped slot. The mounting plate is positioned between the two upright plates and has threaded holes on both sides, allowing bolts to pass through the slots and connect to the threaded holes on the mounting plate. The mounting plate has multiple mounting holes.

[0009] After loosening the bolts, the mounting plate can move and rotate between the two upright plates to fine-tune the distance and angle between the steering wheel robot and the steering wheel. Then tighten the bolts to press the upright plates together and fix the mounting plate and the steering wheel robot in place.

[0010] Furthermore, the clamp includes a housing, sliders, chucks, and a screw. The two sliders are movably disposed inside the housing and can move closer to or further away from each other. One end of each of the two chucks is disposed on the two sliders respectively, and the other end is located outside the housing. The screw is threadedly connected to the housing and is connected to a transmission block. The sides of the two sliders that are close to each other have inclined surfaces, and T-shaped grooves are formed on the inclined surfaces along the inclined direction. The transmission block is located between the two sliders and is slidably connected to the grooves. The housings of the two clamps are respectively connected to the slide bar and the fixing frame.

[0011] Rotating the screw relative to the housing allows it to move axially, which in turn moves the transmission block. With the help of the T-shaped sliding groove, the transmission block can drive the two sliders to move relative to each other, moving them closer or further apart, thus causing the chuck to clamp onto or release from the car door.

[0012] Furthermore, a rubber layer is provided on the side of each of the two clamps that are close to each other.

[0013] The rubber layer prevents damage to the paint and door when the door is clamped.

[0014] Furthermore, the bottom of the outer casing is provided with a T-shaped groove, and the bottom of the slider is slidably connected to the groove.

[0015] The slider engages with the second T-shaped groove, allowing the slider to move only along the direction of the second groove.

[0016] Furthermore, the bottom of the screw is rotatably connected to the transmission block, and the top extends to the outside of the housing and is provided with a handle.

[0017] When the screw is turned using the handle, the screw rotates relative to the transmission block, causing the transmission block to move up and down.

[0018] Furthermore, the sleeve has multiple circumferential openings at the end furthest from the fixing frame, and the clamp is fitted onto the openings.

[0019] The sleeve has multiple openings at its end, which allows it to deform slightly when the clamp is tightened, so that it can hold the slide rod tightly, preventing the slide rod from moving or rotating.

[0020] Furthermore, the clamp includes two U-shaped clips, which are sleeved on the sleeve and connected at both ends by bolts and nuts.

[0021] By connecting and tightening the two ends of the two U-shaped clamps with bolts and nuts, the clamps can be tightened and held on the outside of the sleeve and slide rod, thus fixing the sleeve and slide rod. Attached Figure Description

Detailed Implementation

[0024] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0025] Please see Figures 1 to 4This utility model provides a steering wheel robot tooling for K&C testing, including a mounting base 10, a rotating moving base 20 and a clamp 30. The mounting base 10 is used to mount the steering wheel robot. The spacing and angle can be adjusted by rotating the moving base 20 and the clamp 30. After being fixed on the car door, the steering wheel can be simulated to conduct vehicle testing.

[0026] Specifically, the mounting base 10 can be used to mount the steering wheel robot. The rotating moving base 20 includes a fixed frame 21 and a sleeve 22. The mounting base 10 is mounted on the fixed frame 21, and the sleeve 22 is located on one side of the fixed frame 21. Two clamps 30 are symmetrically provided, and both can be clamped onto the car door. One clamp 30 is provided with a sliding rod 23, which can slide into the sleeve 22 and pass through the fixed frame 21. The sleeve 22 is provided with a clamp 24. The other clamp 30 is fixedly connected to the other side of the fixed frame 21.

[0027] The steering wheel robot for testing is mounted on the mounting base 10. The sleeve 22 slides and rotates on the slide bar 23. Sliding allows for quick adjustment of the relative distance between the two clamps 30 to accommodate vehicles of different widths, while rotation adjusts the orientation of the mounting base 10 and the steering wheel robot. After adjustment, the sleeve 22 and slide bar 23 are secured with clamps 24, allowing the two clamps 30 to be clamped onto the left and right doors of the vehicle. With the steering wheel robot aligned with the steering wheel, it can then simulate steering wheel operations to begin vehicle testing.

[0028] Specifically, such as Figure 1 and Figure 2 As shown, the mounting base 10 includes a base plate 11, a vertical plate 12, and a mounting plate 13. The base plate 11 is mounted on the fixed frame 21, and a pressure plate 14 is provided below the base plate 11. The base plate 11 and the pressure plate 14 are connected to each other by bolts and are located on the upper and lower sides of the fixed frame 21, respectively. The bolts can press and fix the base plate 11 and the pressure plate 14 to the fixed frame 21. When the bolts are loosened, the mounting base 10 can be moved as a whole on the rotating movable seat 20 to adjust its front-to-back and left-to-right position, and make adaptive fine adjustments according to the distance between it and the steering wheel.

[0029] Two upright plates 12 are erected and fixedly mounted on the base plate 11, each with an arc-shaped slotted hole 121. A mounting plate 13 is positioned between the two upright plates 12, and threaded holes are provided on both sides. Bolts can pass through the slotted holes 121 and connect to the threaded holes of the mounting plate 13. The mounting plate 13 has multiple mounting holes for mounting the steering wheel robot. When the bolt is loosened, the mounting plate 13 can move and rotate between the two upright plates 12 to adjust the distance and angle between the steering wheel robot and the steering wheel. Tightening the bolt presses it against the upright plates 12, thus fixing the mounting plate 13 and preventing it from moving or rotating.

[0030] Specifically, such as Figure 1 and 3 As shown, the clamp 30 includes a housing 31, sliders 32, chucks 33, and a screw 34. The two housings 31 are respectively connected to the slide bar 23 and the fixing frame 21. Each housing 31 has two movable sliders 32 that can move closer to or further away from each other. One end of each chuck 33 is mounted on one of the two sliders 32, and the other end is located outside the housing 31. The bottom of the housing 31 has an opening for the chucks 33 to extend and move. The screw 34 is threaded to the top of the housing 31, with a transmission block 35 rotatably connected to one end, and a handle 341 located outside. The sides of the two sliders 32 that are close to each other each have an inclined surface, and a T-shaped groove 321 is formed on the inclined surface along the inclined direction. The transmission block 35 is located between the two sliders 32 and is slidably connected to the groove 321. The bottom of the housing 31 also has a second T-shaped groove 321, and the sliders 32 slide in contact with the second groove 321 to achieve a limiting effect.

[0031] Rotating the screw 34 using the handle 341 allows it to move axially, causing the transmission block 35 to move as well. Because the slider 32 is restricted by the second slide groove 321, the transmission block 35, in conjunction with the T-shaped slide groove 321, can drive the two sliders 32 to move relative to each other. When rising, the sliders 32 move closer together; when falling, they move further apart, thus allowing the clamp 33 to clamp onto or release from the car door. In this embodiment, a rubber layer is provided on the side of the two clamps 33 that are close to each other to prevent damage to the car paint and the door when clamping it.

[0032] Specifically, such as Figure 4 As shown, the end of the sleeve 22 away from the fixed frame 21 has multiple openings in the circumferential direction. The clamp 24 is fitted into the openings, so that it can be slightly deformed when the clamp 24 is tightened, so as to hold it tightly on the slide rod 23, making the slide rod 23 unable to move or rotate.

[0033] In this embodiment, the clamp 24 includes two U-shaped clips, which are sleeved on the sleeve 22 and connected at both ends by bolts and nuts. By connecting and tightening the two ends of the two U-shaped clips with bolts and nuts, the clamp 24 can be tightened and clamped on the outside of the sleeve 22 and the slide rod 23, so that the sleeve 22 and the slide rod 23 are relatively fixed.

[0034] The working principle of the aforementioned steering wheel robot fixture for K&C testing is as follows: The steering wheel robot for testing is mounted on the mounting base 10. The sleeve 22 slides and rotates on the slide bar 23. Sliding is used to adjust the relative distance between the two clamps 30 to suit different vehicle widths. Rotation is used to adjust the orientation of the steering wheel robot. The mounting plate 13 can also be rotated relative to the upright plate 12 to adjust the distance and angle between the steering wheel robot and the steering wheel. After adjustment, the sleeve 22 and slide bar 23 are fixed by the clamp 24 so that the two clamps 30 can be aligned with the left and right doors of the vehicle. Rotating the screw 34 drives the transmission block 35 to rise, and the two sliders 32 move closer together so that the clamps 33 clamp onto the doors, allowing the steering wheel robot to simulate the operation of the steering wheel.

[0035] Using the aforementioned steering wheel robot fixture for K&C testing, the spacing between the two clamps can be adjusted to suit vehicles of different widths, and the angle and orientation can also be adjusted to improve the compatibility between the robot and the steering wheel.

[0036] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model, and they should all be covered within the scope of the claims and specification of this utility model.
