Description

Technical Field

[0001] This utility model relates to the field of racing car shock absorbers, specifically a racing car shock absorber with adjustable damping. Background Technology

[0002] The development of racing shock absorbers (also known as dampers) is closely related to the needs of motorsport. Their technological evolution has gone through a process from passive mechanical to active intelligent. Racing shock absorbers have evolved from passive mechanical to today's electronically controlled intelligent technology, with the core focus on three major goals: lightweighting, precise damping control, and reliability under extreme conditions. In the future, they will further integrate AI, new materials, and energy recovery technologies, becoming a key area for racing performance competition.

[0003] The main function of shock absorbers is to control the vibration of springs, maintain tire contact with the ground, and ensure vehicle stability, comfort, and safety. Traditional shock absorbers often lack damping adjustment mechanisms, making it impossible to adjust the damping of shock absorbers in a timely manner, which leads to inconvenience in adapting to changing track conditions and reduced driving control. Utility Model Content

[0004] To address the shortcomings of existing technologies, such as the inability to adjust shock absorber damping in a timely manner, which leads to difficulties in adapting to changing track conditions and reduced driving control, this invention proposes a racing car shock absorber with adjustable damping.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a racing car shock absorber with adjustable damping, including a shock absorber housing, a shock absorber spring fixedly connected to one side of the shock absorber housing, a top cover fixedly connected to one end of the shock absorber spring, a telescopic rod fixedly connected to one side of the top cover, the surface of the telescopic rod being slidably connected to the inner cavity of the shock absorber housing, and a damping adjustment mechanism provided on the inner wall of the shock absorber housing;

[0006] The damping adjustment mechanism includes a return oil cylinder, the surface of which is fixedly connected to the inner wall of the shock absorber housing. An adjusting plate is rotatably connected to the inner wall of the return oil cylinder. There are multiple adjusting plates, and a rotating rod is fixedly connected to the inner wall of each adjusting plate. A gear is fixedly connected to one end of each rotating rod. A rack is slidably connected to the inner wall of the shock absorber housing. The teeth of the gear mesh with the teeth of the rack. A transmission mechanism is provided on the inner wall of the shock absorber housing.

[0007] Preferably, the transmission mechanism includes a motor, one side of which is fixedly connected to the inner wall of the shock absorber housing, and the output end of the motor is fixedly connected to a screw, the surface of which is threadedly connected to the inner wall of the rack.

[0008] Preferably, a sliding cylinder is fixedly connected to the inner wall of the shock absorber housing, and a piston is fixedly connected to one side of the telescopic rod, with the surface of the piston slidably connected to the inner wall of the sliding cylinder.

[0009] Preferably, a guide rod is fixedly connected to the inner wall of the shock absorber housing, and the surface of the guide rod is slidably connected to the inner cavity of the rack.

[0010] Preferably, an insulating plate is fixedly connected to the inner wall of the shock absorber housing, and the inner cavity of the insulating plate is sleeved on the surface of the rotating rod.

[0011] Preferably, an oil passage plate is fixedly connected to the inner cavity of the sliding cylinder, the inner cavity of the oil passage plate is sleeved on the surface of the telescopic rod, and a through hole is opened on the surface of the piston.

[0012] Preferably, an elastic deformation ring is fixedly connected to the inner wall of the sliding cylinder, and one end of the elastic deformation ring is fixedly connected to the inner cavity of the shock absorber housing.

[0013] The advantages of this utility model are:

[0014] This invention utilizes a damping adjustment mechanism. When the top cover is pressed down, the telescopic rod moves the piston downward, pushing the damping oil in the sliding cylinder towards the return cylinder. The damping oil is then obstructed by a set of adjusting plates, increasing the oil pressure in the return cylinder. The damping oil can only flow through the gaps between the adjusting plates. Because the damping oil itself has limited fluidity, the flow rate through the adjusting plates per unit time is related to the size of the gaps. The sliding rack drives the gears on its meshing left and right sides to rotate, which in turn drives the rotating rod fixedly connected to it to rotate. The rotating rod drives the adjustment plates to rotate, thus changing the size of the gaps between the adjusting plates, thereby changing the damping effect of the damping oil on the pressure. This achieves the effect of adjusting the damping, solving the problems of not being able to adjust the shock absorber damping in time, leading to inconvenience in adapting to changing track conditions and reduced driving control.

[0022] 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 scope of protection of the present utility model.

[0023] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0024] This application discloses an adjustable damping racing car shock absorber. (Refer to...) Figures 1 to 4 A damping adjustable racing car shock absorber includes a shock absorber housing 1, a shock absorber spring 2 fixedly connected to one side of the shock absorber housing 1, a top cover 3 fixedly connected to one end of the shock absorber spring 2, a telescopic rod 4 fixedly connected to one side of the top cover 3, the surface of the telescopic rod 4 being slidably connected to the inner cavity of the shock absorber housing 1, and a damping adjustment mechanism 5 provided on the inner wall of the shock absorber housing 1.

[0025] The damping adjustment mechanism 5 includes a return oil cylinder 501, the surface of which is fixedly connected to the inner wall of the shock absorber housing 1. Multiple adjustment plates 502 are rotatably connected to the inner wall of the return oil cylinder 501. A rotating rod 503 is fixedly connected to the inner wall of each adjustment plate 502. A gear 504 is fixedly connected to one end of each rotating rod 503. A rack 505 is slidably connected to the inner wall of the shock absorber housing 1. The teeth of the gear 504 mesh with the teeth of the rack 505. The inner wall of the shock absorber housing 1 is equipped with a transmission mechanism 6. A damping adjustment mechanism 5 is provided, with multiple adjustment plates 502 arranged in pairs. When the top cover 3 is pressed down, the telescopic rod 4 drives the piston 8 downwards. The piston 8 pushes the damping oil in the sliding cylinder 7 towards the return oil cylinder 501. The damping oil is then obstructed by a set of adjustment plates 502, increasing the oil pressure in the return oil cylinder 501. The damping oil can only flow through the gaps between the adjustment plates 502. The flow rate through the regulating plate 502 per unit time is limited, and is related to the size of the gap between the regulating plates 502. The sliding rack 505 drives the left and right gears 504 meshing with it to rotate, and then the gears 504 drive the rotating rod 503 fixedly connected to it to rotate. The rotating rod 503 drives the rotation of the regulating plate 502, thereby changing the size of the gap between the regulating plates 502, thus changing the damping of the damping oil on the pressure. Due to the sloping structure of the regulating plate 502, the damping oil increases at the convex end of the regulating plate 502 when the top cover 3 is pressed down. The damping oil will impact the sloping surface of the regulating plate 502. The flow direction of the damping oil is opposite to the opening direction of the regulating plate 502, thereby slowing down the opening of the regulating plate 502. When the top cover 3 is reset and moved upward, the damping oil increases at the concave end of the regulating plate 502. The damping oil will impact the sloping surface of the regulating plate 502. The flow direction of the damping oil is the same as the opening direction of the regulating plate 502, thereby assisting the opening of the regulating plate 502 and achieving rapid reset.

[0026] Reference Figure 4 The transmission mechanism 6 includes a motor 601. One side of the motor 601 is fixedly connected to the inner wall of the shock absorber housing 1. A screw 602 is fixedly connected to the output end of the motor 601. The surface of the screw 602 is threadedly connected to the inner wall of the rack 505. By setting the transmission mechanism 6, the motor 601 works and drives the screw 602 at its output end to rotate. The rotation of the screw 602 drives the rack 505 threadedly connected to it to move, thereby converting the rotation of the screw 602 into the axial movement of the rack 505, thus providing power to the damping adjustment mechanism 5.

[0027] Reference Figure 3A sliding cylinder 7 is fixedly connected to the inner wall of the shock absorber housing 1, and a piston 8 is fixedly connected to one side of the telescopic rod 4. The surface of the piston 8 is slidably connected to the inner wall of the sliding cylinder 7. By setting the sliding cylinder 7 and the piston 8, the sliding cylinder 7 is connected to the return oil cylinder 501. When the top cover 3 moves down, the top cover 3 pushes the telescopic rod 4 to move down, and the telescopic rod 4 pushes the piston 8 to move, so that the piston 8 can push the damping oil in the sliding cylinder 7 into the return oil cylinder 501.

[0028] Reference Figure 4 A guide rod 9 is fixedly connected to the inner wall of the shock absorber housing 1. The surface of the guide rod 9 is slidably connected to the inner cavity of the rack 505. By setting the guide rod 9, since the surface of the guide rod 9 is slidably connected to the inner cavity of the rack 505 and the guide rod 9 is fixedly connected to the inner wall of the shock absorber housing 1, the guide rod 9 can limit the rack 505 and improve the stability of the damping adjustment mechanism 5.

[0029] Reference Figure 4 An isolation plate 10 is fixedly connected to the inner wall of the shock absorber housing 1. The inner cavity of the isolation plate 10 is sleeved on the surface of the rotating rod 503. By setting the isolation plate 10, the isolation plate 10 can isolate the damping adjustment mechanism 5 and the transmission mechanism 6 from the damping oil environment, preventing the damping oil leakage from affecting the normal operation of the damping adjustment mechanism 5 and the transmission mechanism 6.

[0030] Reference Figure 5 An oil passage plate 11 is fixedly connected to the inner cavity of the sliding cylinder 7. The inner cavity of the oil passage plate 11 is sleeved on the surface of the telescopic rod 4. A through hole 12 is opened on the surface of the piston 8. By setting the oil passage plate 11, the damping oil in the return oil cylinder 501 can flow back to the sliding cylinder 7 during the pressure process, and the damping oil in the sliding cylinder 7 can flow to the return oil cylinder 501 when the shock absorber spring 2 is reset. By setting the through hole 12, the damping oil can flow into the annular groove inside the piston 8 through the through hole 12, thereby pushing the piston 8 inside the piston 8.

[0031] Reference Figure 5 An elastic deformation ring 13 is fixedly connected to the inner wall of the sliding cylinder 7. One end of the elastic deformation ring 13 is fixedly connected to the inner cavity of the shock absorber housing 1. By setting the elastic deformation ring 13, under normal conditions, the elastic deformation ring 13 can impede the flow of damping oil to a certain extent. When the pressure inside the sliding cylinder 7 is too high, the damping oil pushes the elastic deformation ring 13 to deform the elastic deformation ring 13, thereby expanding the aperture of the elastic deformation ring 13 and reducing the impeding ability of the elastic deformation ring 13, thereby dynamically adjusting the damping.

[0032] Working principle: Multiple adjusting plates 502 are provided, with each pair of contactable adjusting plates 502 forming a group. The sliding cylinder 7 and the return oil cylinder 501 are connected. When the top cover 3 moves down, the top cover 3 pushes the telescopic rod 4 down, and the telescopic rod 4 pushes the piston 8 to move. Thus, the piston 8 can push the damping oil in the sliding cylinder 7 into the return oil cylinder 501. Afterward, the damping oil is blocked by multiple groups of adjusting plates 502, which increases the oil pressure in the return oil cylinder 501. The damping oil can only flow through the gaps between the adjusting plates 502. Because the damping oil itself has limited fluidity, the flow rate through the adjusting plates 502 per unit time is related to the size of the gaps between the adjusting plates 502. The motor 601 works, driving the screw 602 at its output end to rotate. The rotation of the screw 602 drives the rack 505, which is threaded to it, to move. The rack 505 drives the left and right gears 504 meshing with it to rotate, and then the gears 504 drive the… The rotating rod 503, which is fixedly connected to it, rotates, causing the adjusting plate 502 to rotate and thus changing the size of the gap between the adjusting plates 502. This changes the damping effect of the damping oil on the pressure. Due to the sloping structure of the adjusting plate 502, the damping oil increases at the convex end of the adjusting plate 502 when the top cover 3 is pressed down. The damping oil impacts the sloping surface of the adjusting plate 502, and the flow direction of the damping oil is opposite to the opening direction of the adjusting plate 502, thereby slowing down the opening of the adjusting plate 502. When the top cover 3 returns to its original position and moves upward, the piston 8 pushes the damping oil above the piston 8 in the sliding cylinder 7 to flow to the return oil cylinder 501, causing the damping oil to increase at the concave end of the adjusting plate 502. The damping oil impacts the sloping surface of the adjusting plate 502, and the flow direction of the damping oil is the same as the opening direction of the adjusting plate 502, thereby assisting the opening of the adjusting plate 502 to widen the gap between a set of adjusting plates 502 and achieve rapid reset.

[0033] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
