Description

Technical Field

[0001] The present invention relates to the technical field of automobile test benches, in particular to an automobile test bench adjusting device. Background Art

[0002] An automobile test bench is a device or facility specifically used to conduct systematic testing of various performance and safety indicators of an automobile. The most common one is the brake test bench, also known as a roller test bench. It is mainly used to measure the braking capacity of an automobile and can quickly, accurately and quantitatively detect and calculate the blocking force, braking force and parking brake force of the left and right wheels of the automobile.

[0003] When a car is being tested, the car's drive wheels need to be driven onto the test bench. Currently, when the car is being tested, there is a problem that the wheels cannot be accurately aligned with the rollers on the test bench. The main reason is that there will inevitably be deviations when the vehicle is parked on the test bench (the vehicle cannot be completely parallel to the test bench when it enters the test bench), resulting in the two drive wheels being unable to stop neatly between the two rollers on the test bench (that is, the vehicle cannot remain parallel to the test bench). This also causes the car to be in an irregular state at the beginning of the test, which inevitably affects the final test structure of the vehicle. Therefore, it is necessary to propose an automobile test bench adjustment device. Summary of the Invention

[0004] In order to solve the above technical problems, the present invention provides an adjusting device for an automobile testing platform.

[0005] The present invention is implemented by the following technical solutions: a base, on which a turntable and a plank bridge rotating with the turntable as the rotation axis are rotatably arranged; The turntable and the bridge are each equipped with two inclination detection mechanisms and a test platform. The four inclination detection mechanisms are located at both ends of the two test platforms to detect the deflection angle of the car. The turntable and the bridge are then used to adjust the angles of the two test platforms to accurately match the car wheels. The base is also provided with a lifting frame that can be moved and raised to lift the vehicle body to facilitate angle adjustment of the turntable and the bridge.

[0006] As a further improvement of the above solution, the inclination angle detection mechanism includes a mounting frame and two laser angle detectors arranged on the mounting frame, so as to determine the overall inclination angle of the vehicle by detecting the angle of the vehicle wheels.

[0007] As a further improvement of the above solution, an electric push rod is also fixed on the mounting frame. A feedback plate is hinged on the output rod of the electric push rod, which is aligned with the two laser angle detectors and can self-correct. By pressing the feedback plate against the car wheel, the laser angle detector is assisted in performing offset angle detection, so that the inclination detection mechanism can adapt to wheels of different sizes, avoiding the laser angle detector from being unable to perform detection normally.

[0008] As a further improvement of the above solution, a load-bearing groove that can be moved horizontally is provided on the board bridge, and the inspection platform provided on the board bridge is located in the load-bearing groove, which is used to adjust the position of the inspection platform to meet the inspection requirements of four-wheel drive vehicles with different wheelbases.

[0009] As a further improvement of the above scheme, two L-shaped support frames are provided at both ends of the bearing slot, and the two L-shaped support frames are fixedly connected to the corresponding two inclination detection mechanisms respectively, so that the corresponding inclination detection mechanisms can move synchronously with the bearing slot to be suitable for cars with different wheelbases.

[0010] As a further improvement of the above solution, multiple groups of transversely arranged slots are provided on the board bridge, and multiple horizontal bars paired with the slots are provided on both sides of the load-bearing groove, so as to meet the position adjustment requirements of the inspection platform on the load-bearing groove, while also avoiding the occurrence of leakage between the board bridge and the inspection platform to affect the passage of vehicle wheels.

[0011] As a further improvement of the above solution, both ends of the board bridge are arc-shaped structures, so that when it is combined with the inner arc-shaped platform, there will be no leakage at the connection with the platform, and the angle can be adjusted by rotation without restriction.

[0012] As a further improvement of the above solution, a storage groove for storing the lifting frame is provided on the plank bridge, so as to prevent the lifting frame from obstructing the wheels.

[0013] As a further improvement of the above scheme, two rectangular openings are provided on the lifting frame, and pads with a lower center of gravity are rotatably installed in the two rectangular openings. Driven gears are fixedly sleeved on the shafts of the two pads, and two touch racks are fixedly installed on the bottom inner wall of the storage groove, which are respectively engaged with the two driven gears. A counterweight block that can change its center of gravity is slidably installed in the pad.

[0014] Compared with the prior art, the present invention has the following beneficial effects: The adjustment device for the test bench is composed of a base, a turntable, a bridge, an inclination detection mechanism, and a lifting frame. When the vehicle wheels drive onto the test bench, the angle of the test bench can be adjusted according to the vehicle's deflection angle, so that the vehicle wheels can be more accurately aligned with the test bench, thereby ensuring the accuracy of the vehicle's brake testing. In addition, it is also suitable for testing two-wheel drive and four-wheel drive vehicles, thereby expanding its scope of application. Since the wheel sizes and wheel hub shapes of different vehicles are different, the laser angle detector is prone to being unable to align with the wheel when detecting the vehicle's offset angle through the wheel, resulting in failure to complete the detection smoothly. By providing an electric push rod and a feedback plate that is hinged to the electric push rod and can automatically correct itself on the inclination detection mechanism, the laser angle detector can use the feedback plate as the detection object, making the inclination detection mechanism suitable for different types of vehicles; By setting two tension springs between the hinge joint and the feedback plate, it is possible to prevent the feedback plate from moving arbitrarily and failing to smoothly reach the wheel for deflection angle detection, and it is also possible to prevent it from scratching the car body.

[0015] By arranging pads on the lifting frame, the lifting frame will not cause damage to the car chassis when lifting the car. At the same time, it can also adapt to the angle changes that occur when the car is lifted, avoiding the front wheels of the car from slipping from the inspection table due to tilting when the car is lifted, resulting in inaccurate alignment. By arranging driven gears and counterweights on the pads, and arranging a touch rack for cooperating with the driven gear in the storage groove, the pads can be flipped as the lifting frame rises and falls, thereby automatically realizing the switching between the raised mode and the storage mode, avoiding the pads from being crushed and damaged for a long time, affecting the normal use of the lifting frame.

[0018] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0019] Please combine Figures 1 to 10 , an automobile inspection platform adjustment device, comprising: a base 1, a turntable 2 and a board bridge 3 that rotates with the turntable 2 as the rotation axis are rotatably provided on the base 1, the base 1, the turntable 2 and the bottom of the board bridge 3 are provided with reinforcing ribs, so as to reduce the weight while ensuring the overall quality, wherein one end of the board bridge 3 is rotatably mounted on the turntable 2, and the other end thereof is provided with an arc-shaped pier 305, and the base 1 is provided with an arc-shaped slide rail that cooperates with the arc-shaped pier 305, and a first motor 4 and a second motor 7 are fixedly mounted on the base 1, a worm 5 is provided on the output shaft of the first motor 4, and a worm gear ring 6 that cooperates with the worm 5 is fixedly sleeved on the turntable 2 to drive the turntable 2 to rotate, a driving gear 8 is fixedly mounted on the output shaft of the second motor 7, and an arc-shaped rack 9 that meshes with the driving gear 8 is fixedly mounted on the arc-shaped pier 305 of the board bridge 3, so as to realize the angle adjustment of the driving board bridge 3; Two inclination detection mechanisms 10 and a test platform 14 are respectively provided on the turntable 2 and the bridge 3. The turntable 2 is provided with a placement slot 201, and the test platform 14 on it is placed in the placement slot 201. Four inclination detection mechanisms 10 are respectively located at both ends of the two test platforms 14 to detect the deflection angle of the car. The turntable 2 and the bridge 3 are then used to adjust the angles of the two test platforms 14 to accurately match the car wheels. The base 1 is also provided with a lifting frame 13 that can be moved and lifted. An electric slide rail 11 is fixedly installed on the base 1. Second hydraulic push rods 12 are provided on the two moving platforms of the electric slide rail 11. The output rods of the two second hydraulic push rods 12 are fixedly connected to the bottom of the lifting frame 13, so as to lift the vehicle body to facilitate the angle adjustment of the turntable 2 and the board bridge 3. In addition, space is reserved between the two second hydraulic push rods 12 and the board bridge 3 for adjusting the angle of the board bridge 3.

[0020] Through the above technical solution, when the vehicle wheels drive onto the inspection platform 14, the angle of the inspection platform 14 can be adjusted according to the deflection angle of the vehicle, so that the wheels of the vehicle can be aligned with the inspection platform 14 more accurately, thereby ensuring the accuracy of the vehicle braking detection. In addition, it is also suitable for the detection of two-wheel drive and four-wheel drive vehicles, thereby increasing its scope of application.

[0021] Please combine Figure 7 The inclination detection mechanism 10 includes a mounting frame 101 and two laser angle detectors 102 arranged on the mounting frame 101, so as to determine the overall inclination angle of the car by detecting the angle of the car wheel. An electric push rod 103 is also fixedly provided on the mounting frame 101, and a feedback plate 105 that is aligned with the two laser angle detectors 102 and can self-correct is hinged on the output rod of the electric push rod 103. A hinge head 104 is fixedly installed on the output rod of the electric push rod 103, and the hinge head 104 is rotatably connected to the feedback plate 105, and two tension springs 106 are provided between the hinge head 104 and the feedback plate 105, so as to limit the swing of the feedback plate 105 without affecting it, and assist the laser angle detector 102 in performing offset angle detection by pressing the feedback plate 105 against the car wheel, so that the inclination detection mechanism 10 can adapt to wheels of different sizes and avoid the laser angle detector 102 from failing to perform detection normally.

[0022] According to the above technical solution, since the wheel sizes and wheel hub shapes of different vehicles are different, the laser angle detector 102 may not be able to align with the wheel when detecting the vehicle offset angle through the wheel, resulting in failure to complete the detection smoothly (laser reflection cannot be achieved normally, and the body of the vehicle cannot be used as a detection object due to the curvature of the body). By providing the electric push rod 103 and the feedback plate 105 that is hinged to the electric push rod 103 and can automatically correct on the inclination detection mechanism 10, the laser angle detector 102 can use the feedback plate 105 as the detection object, so that the inclination detection mechanism 10 can be applied to different types of vehicles. By arranging two tension springs 106 between the hinge joint 104 and the feedback plate 105, it is possible to prevent the feedback plate 105 from moving arbitrarily and failing to smoothly contact the wheel for deflection angle detection, and also to prevent it from scratching the vehicle body.

[0023] Please combine Figure 4 and Figure 6 A load-bearing groove 302 that can be moved horizontally is provided on the board bridge 3, and a first hydraulic push rod 301 is provided on the board bridge 3. The output rod of the first hydraulic push rod 301 is fixedly connected to the load-bearing groove 302. The inspection platform 14 provided on the board bridge 3 is in the load-bearing groove 302, so as to adjust the position of the inspection platform 14 to meet the inspection requirements of four-wheel drive vehicles with different wheelbases.

[0024] Please combine Figure 4 Two L-shaped support frames are provided at both ends of the bearing slot 302, and the two L-shaped support frames are fixedly connected to the corresponding two inclination detection mechanisms 10, so that the corresponding inclination detection mechanisms 10 can move synchronously with the bearing slot 302 to be suitable for cars with different wheelbases.

[0025] Please combine Figure 4 There are multiple groups of transversely arranged slots 303 on the board bridge 3, and multiple horizontal bars 3021 paired with the slots 303 are provided on both sides of the load-bearing groove 302, so as to meet the position adjustment requirements of the inspection platform 14 on the load-bearing groove 302, and at the same time avoid leakage between the board bridge 3 and the inspection platform 14 to affect the passage of vehicle wheels.

[0026] Please combine Figure 1 and Figure 10 Both ends of the bridge 3 are arc-shaped structures, so that when it is connected with the inner arc platform, there will be no leakage at the connection with the platform, and the angle can be adjusted by rotation without restriction.

[0027] Please combine Figure 4 A receiving groove 304 for receiving the lifting frame 13 is provided on the plank bridge 3 to prevent the lifting frame 13 from obstructing the wheels.

[0028] Please combine Figure 8 and Figure 9 The lifting frame 13 is provided with two rectangular openings, and pads 131 with a lower center of gravity are rotatably installed in the two rectangular openings. A rubber layer is laid on the pads 131, and a driven gear 132 is fixedly sleeved on the shafts of the two pads 131. Two touch racks 133 are fixedly installed on the bottom inner wall of the storage groove 304, which are respectively engaged with the two driven gears 132. A counterweight block 134 that can change its center of gravity is slidably installed in the pad 131, so that when the lifting frame 13 is raised, the pad 131 automatically flips into a raised mode, and when the lifting frame 13 is stored in the storage groove 304, the pad 131 automatically flips into a storage mode, so that when the lifting frame 13 lifts the car, the car chassis will not be damaged, and the pad 131 will not be crushed by the wheels when stored.

[0029] Through the above technical solution, by arranging a pad 131 on the lifting frame 13, the lifting frame 13 will not cause damage to the car chassis when lifting the car. At the same time, it can also adapt to the angle changes that occur when the car is lifted, and avoid the front wheels of the car from slipping from the inspection platform 14 due to tilting when the car is lifted, resulting in inaccurate alignment. By arranging a driven gear 132 and a counterweight block 134 on the pad 131, and arranging a touch rack 133 for cooperating with the driven gear 132 in the storage groove 304, the pad 131 can be flipped along with the lifting and lowering of the lifting frame 13, thereby automatically realizing the switching between the raised mode and the storage mode, and avoiding the pad 131 being crushed and damaged for a long time, affecting the normal use of the lifting frame 13.

[0030] The implementation principle of an automobile test bench adjustment device in the embodiment of the present application is as follows: When building the platform, reserve a groove for placing the entire adjustment device; When a vehicle (a two-wheel drive vehicle) is to be inspected, the entire vehicle body needs to be driven onto the plank bridge 3, and the two front wheels need to be driven onto the inspection platform 14 on the turntable 2. The corresponding electric push rods 103 on the two inclination detection mechanisms 10 drive the feedback plate 105 to rest against the front wheels of the vehicle (before this, the steering wheel of the vehicle needs to be returned to the center to ensure that the wheels are in the centering state). This can detect the inclination angle of the vehicle body. Subsequently, the first motor 4 drives the turntable 2 and the inspection platform 14 arranged on the turntable 2 to rotate, so that the inspection platform 14 remains parallel to the two wheels of the vehicle through rotation, thereby making the alignment of the vehicle wheels and the inspection platform 14 more accurate. When the vehicle is a four-wheel drive vehicle, the first hydraulic push rod 301 is activated to drive the bearing slot 302 and the corresponding inspection platform 14 to move, thereby adjusting the distance between the two inspection platforms 14 according to the vehicle's wheelbase. In order to ensure more accurate alignment of the vehicle's rear wheels with the inspection platform 14, the corresponding two inclination angle detection mechanisms 10 detect the deflection angle of the vehicle's rear half. After the angle detection is completed, the two second hydraulic push rods 12 are activated to push the lifting frame 13 out of the storage slot 304. During this process, the pad 131 is driven by the triggered rack 133 to flip 180 degrees. After the flip is completed, the counterweight block 134 inside it slides down by itself to change its center of gravity, so that the pad 131 changes from bottom-down to bottom-up. Subsequently, the electric slide rail 11 drives the lifting frame 13 to move to the rear half of the vehicle, and starts the second hydraulic push rod 12 to lift the rear half of the vehicle, so that the vehicle is detached from the board bridge 3. At this time, the second motor 7 is started, and the second motor 7 drives the entire board bridge 3 to rotate with the turntable 2 as the axis (and also with the front wheels of the car as the axis) to fine-tune the angle. After adjusting the angle, the car body is lowered to allow the inspection platform 14 to be more accurately aligned with the rear wheels of the vehicle, thereby ensuring that the vehicle inspection results are more accurate.

[0031] The above embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and replacements made by technicians in this field on the basis of the present invention fall within the scope of protection required by the present invention.
