Description

Technical Field

[0001] This utility model belongs to the field of automotive suspension quality testing technology, and relates to an automotive shock absorber suspension fixing mechanism. Background Technology

[0002] A car's shock absorber suspension refers to a series of force-transmitting connections between the car body and the wheels. Its main function is to transmit the forces and torques between the wheels and the car body, while also buffering the impact forces transmitted from uneven road surfaces, ensuring a smooth ride. The shock absorber suspension is a crucial component of a car, therefore its quality is paramount. After the shock absorber suspension is assembled, it needs to be placed on a suspension testing platform and its quality is determined by impact testing. Therefore, a fixing mechanism is required to secure the shock absorber suspension to the testing platform.

[0003] A suspension testing platform for easy synchronous wheel fixing is disclosed in Chinese patent CN218271398U. The platform includes a testing platform with an impact testing component for suspension quality testing installed on its top surface. Two symmetrically arranged through slots are opened on the top surface of the testing platform, and two symmetrically arranged support columns are fixedly installed on the inner bottom surface of the testing platform. A support plate is fixedly installed on the top surface of the support columns and is located in the through slot. The support plate is used to support the wheels of the vehicle suspension.

[0004] When fixing the suspension test bench, the wheel is placed on top of four support plates, and then the motor is activated to drive the clamps to secure the wheel. It cannot be directly fixed during the suspension's downward movement, making it inconvenient to use.

[0005] To solve the above problems, this utility model proposes a vehicle shock absorber suspension fixing mechanism. Utility Model Content

[0006] To address the problems existing in the background technology, this utility model proposes an automotive shock absorber suspension fixing mechanism.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows: it includes a fixed platform, and each of the four corners of the top surface of the fixed platform has a vertically sliding placement seat, and the bottom end of each placement seat is connected to the fixed platform by a first spring.

[0008] The fixed platform is internally symmetrically equipped with two lead screws, each of which is equipped with two sets of driving components. The driving components correspond one-to-one with the placement seat. Each set of driving components includes two threaded segments with opposite directions of rotation. Each threaded segment is equipped with a limit plate, which is horizontally slidably arranged on both sides of the corresponding placement seat.

[0009] Each of the placement seats is equipped with a transmission component, which drives the corresponding lead screw to rotate when the placement seat moves downward.

[0010] Furthermore, a first telescopic rod is fixedly connected between the bottom of each placement seat and the inner bottom surface of the fixed platform, and a first spring located at the bottom end of the placement seat is sleeved on the corresponding first telescopic rod.

[0011] Furthermore, the top surface of the fixed platform is provided with sliding grooves on both sides of each placement seat, and the limiting plate slides through the corresponding sliding groove. The bottom end of each limiting plate is fixedly connected to a movable plate, and the movable plate is threaded onto the corresponding threaded segment.

[0012] Furthermore, each of the limiting plates is fixedly connected to a plurality of second telescopic rods arranged in an array on the side near the corresponding placement seat, and a sleeve is fixedly connected to the end of each second telescopic rod, and a ball bearing is provided at the end of each sleeve away from the second telescopic rod.

[0013] Each of the second telescopic rods is fitted with a second spring. One end of the second spring is fixedly connected to one side of the limiting plate, and the other end of the second spring is fixedly connected to one side of the sleeve.

[0014] Furthermore, the transmission component includes a rack, which is fixedly connected to one side of the bottom of the placement seat. The lead screw is fixedly fitted with a third gear at each driving component. The third gear is located between two corresponding threaded segments with opposite directions of rotation, and the third gear meshes with the corresponding rack.

[0015] Both of the lead screws have their ends rotatably passing through the side of the fixed platform, and each lead screw has a second gear coaxially fixedly connected to one end extending outside the fixed platform.

[0016] A motor is fixedly connected to each of the second gears on one side of the fixed platform. A one-way bearing is fixedly fitted on the output shaft of each motor. A first gear is fixedly fitted on each one-way bearing. The first gear meshes with the corresponding second gear.

[0017] Furthermore, each of the placement seats has a groove on its top surface, and the bottom surface of the groove is arc-shaped.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. This automotive shock absorber suspension fixing mechanism is equipped with four mounting seats. When fixing the assembled automotive shock absorber suspension, the four wheels of the automotive shock absorber suspension are moved onto the four mounting seats respectively. Due to the weight, the mounting seats will be pressed downward, causing the rack to move downward, driving the third gear and the lead screw to rotate. The threaded section will drive the moving plate and the limiting plate to move, so that the corresponding two limiting plates are brought closer to each other, and the balls abut against the wheels. This allows the automotive shock absorber suspension to be automatically fixed during the placement process without the need for additional fixing operations, making it more convenient to use.

[0020] 2. The car shock absorber suspension fixing mechanism is equipped with a one-way bearing. When the mounting seat moves downward to fix the car shock absorber suspension, the second gear drives the first gear to rotate, and the one-way bearing rotates freely. When the car shock absorber suspension is moved out, the motor drives the one-way bearing to rotate. At this time, the one-way bearing is locked, which drives the second gear to rotate, so that the two limiting plates move away from each other, allowing the limiting plates to leave the wheel and thus the car shock absorber suspension can be moved out directly. The operation is simple. Attached Figure Description

[0025] 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.

[0026] like Figures 1-3 As shown, the technical solution adopted by this utility model is as follows: A car shock absorber suspension fixing mechanism includes a fixing platform 1, with placement seats 8 vertically sliding through the four corners of the top surface of the fixing platform 1. The bottom end of each placement seat 8 is connected to the fixing platform 1 by a first spring. The placement seat 8 is positioned on the fixing platform 1 by the first spring.

[0027] Each mounting base 8 has a groove on its top surface, and the bottom surface of the groove is arc-shaped. This allows the shape of the bottom surface of the groove to match the shape of the wheel on the car's shock absorber suspension, thus facilitating better wheel fixation.

[0028] Each placement seat 8 is fixedly connected to the inner bottom surface of the fixed platform 1 with a first telescopic rod 10. A first spring located at the bottom end of the placement seat 8 is sleeved on the corresponding first telescopic rod 10. In the initial state, the first spring pushes the placement seat 8 upward, causing the first telescopic rod 10 to extend to its longest state, so that the wheel can be placed on the placement seat 8.

[0029] The fixed platform 1 has two symmetrically rotating lead screws 6 inside, each lead screw 6 equipped with two sets of driving components, each driving component corresponding to a placement seat 8. Each set of driving components includes two threaded sections with opposite directions of rotation, and each threaded section is equipped with a limiting plate 12. The limiting plates 12 are horizontally slidably disposed on both sides of the corresponding placement seat 8, so that the placement seat 8 is positioned between the two limiting plates 12.

[0030] The top surface of the fixed platform 1 has sliding grooves on both sides of each placement seat 8, and the limiting plate 12 slides through the corresponding sliding groove. The sliding grooves position the movement of the limiting plate 12. The bottom end of each limiting plate 12 is fixedly connected to a movable plate 11, which is threaded onto the corresponding threaded section. When the lead screw 6 rotates, the threaded section drives the movable plate 11 and the limiting plate 12 to move, and the two movable plates 11 on each set of driving components move in opposite directions.

[0031] Each limiting plate 12 has several second telescopic rods 13 fixedly connected to one side near the corresponding placement seat 8, arranged in an array. Each end of the second telescopic rod 13 is fixedly connected to a sleeve 14, and a ball bearing 15 is provided at the end of each sleeve 14 away from the second telescopic rod 13. The ball bearing 15 can roll inside the sleeve 14, and a part of the ball bearing 15 extends outside the sleeve 14.

[0032] Each second telescopic rod 13 is fitted with a second spring. One end of the second spring is fixedly connected to one side of the limiting plate 12, and the other end of the second spring is fixedly connected to one side of the sleeve 14. In the initial state, the second spring pushes the sleeve 14, causing the second telescopic rod 13 to extend to its longest position.

[0033] Each placement seat 8 is equipped with a transmission component, which drives the corresponding lead screw 6 to rotate when the placement seat 8 moves downward.

[0034] The transmission component includes a rack 9, which is fixedly connected to one side of the bottom of the placement base 8. The rack 9 slides through the top surface of the fixed platform 1. A third gear 7 is fixedly fitted onto each drive component of the lead screw 6. The third gear 7 is located between two corresponding threaded segments with opposite directions of rotation and meshes with the corresponding rack 9. This allows the rack 9 to drive the corresponding third gear 7 to rotate as the placement base 8 moves, thereby causing the lead screw 6 to rotate.

[0035] The ends of both lead screws 6 rotate through the side of the fixed platform 1, and the end of each lead screw 6 extending outside the fixed platform 1 is coaxially fixedly connected to a second gear 5.

[0036] A motor 2 is fixedly connected to one side of the fixed platform 1 at each of the second gears 5. A one-way bearing 3 is fixedly fitted on the output shaft of each motor 2, and a first gear 4 is fixedly fitted on each one-way bearing 3. The first gear 4 meshes with the corresponding second gear 5, so that each lead screw 6 is driven by one motor 2.

[0037] Working principle:

[0038] The assembled car shock absorber suspension is lifted upwards using a robotic arm or hoisting equipment, so that the car shock absorber suspension is directly above the fixed platform 1, and the four wheels of the car shock absorber suspension correspond one-to-one with the four placement seats 8.

[0039] Lower the car's shock absorber suspension downwards so that the wheels are positioned on their respective mounting seats 8. The wheels are positioned between the two corresponding limiting plates 12.

[0040] As the wheel moves downwards, gravity presses down on the placement seat 8, causing it to slide vertically downwards. The placement seat 8 then compresses the first spring, shortening the first telescopic rod 10.

[0041] The placement seat 8 drives the rack 9 to move downwards. When the rack 9 moves, it drives the corresponding third gear 7 to rotate, causing the lead screw 6 to rotate.

[0042] When the lead screw 6 rotates, it drives the moving plate 11 to move through the threaded section, causing the limiting plate 12 to slide on the slide groove. Since each set of driving components includes two threaded sections with opposite directions of rotation, the corresponding two limiting plates 12 move towards each other.

[0043] At the same time, the lead screw 6 drives the second gear 5 to rotate, and the second gear 5 drives the first gear 4 to rotate. At this time, the one-way bearing 3 rotates freely, and the output shaft of the motor 2 does not rotate.

[0044] The limiting plate 12 moves the second telescopic rod 13, sleeve 14, and ball bearings 15. The ball bearings 15 first contact the wheel. Due to the irregular shape of the wheel, several ball bearings 15 will abut against different points on the wheel, thereby compressing the corresponding second spring and shortening the second telescopic rod 13 to a suitable length. When the wheel moves downward, the limiting plate 12 automatically fixes the wheel, thereby fixing the vehicle's shock absorber suspension.

[0045] During disassembly, motor 2 is started, and the output shaft of motor 2 drives the one-way bearing 3 to rotate. At this time, the one-way bearing 3 is locked, driving the first gear 4 to rotate. The first gear 4 drives the second gear 5 to rotate, causing the lead screw 6 to rotate. The threaded section drives the moving plate 11 and the limiting plate 12 to move, causing the two corresponding limiting plates 12 to move in opposite directions.

[0046] The limiting plate 12 moves one end of the second spring. Since the second spring is compressed, it drives the ball bearing 15 to contact the wheel, causing the second telescopic rod 13 to extend. After the second spring returns to its initial state, it moves the sleeve 14 and the ball bearing 15, causing the ball bearing 15 to leave the wheel. A robotic arm or lifting equipment is then used to lift the inspected car shock absorber suspension upwards.

[0047] During the upward movement of the car's shock absorber suspension, the first spring pushes the mounting seat 8 upward, causing the first telescopic rod 10 to extend until it returns to its initial state, at which point the mounting seat 8 stops moving upward.

[0048] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
