Abstract
Description
Technical Field
[0001] This utility model relates to the field of vibration reduction technology, specifically a high-performance double wishbone suspension vibration damper. Background Technology
[0002] The double wishbone suspension system has significant advantages. The upper and lower wishbones work together to absorb lateral forces, allowing the shock absorbers to focus on filtering vertical vibrations. This reduces body roll during cornering by 15%-20% compared to the MacPherson strut suspension. The shock absorbers are installed closer to the wheel center, and combined with the unequal-length wishbone structure, it can precisely control the wheel's trajectory, improving vibration filtering efficiency by more than 30%. By adjusting the wishbone geometry (such as camber and toe angles), it can be adapted to different driving scenarios.
[0003] Existing double wishbone suspension dampers have a single damping coefficient, which cannot be adjusted under different road conditions and needs. With the development of technology, especially with the vigorous development of new energy vehicles, kinetic energy recovery and utilization are gradually developing rapidly in the automotive field. When a vehicle passes through a bumpy road, the extension and retraction ends of the damper will extend and retract. Therefore, we can use the vibration force of the bumps for energy recovery to improve the vehicle's range performance. Thus, we propose a high-performance double wishbone suspension damper.

Detailed Implementation
[0023] 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.
[0024] This utility model embodiment provides a high-performance double wishbone suspension damper, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, it includes buffer 1;
[0025] Electromagnetic component 2 includes a mounting component 201. The bottom of the mounting component 201 is fixedly connected to the top of the buffer 1. A first extension plate 202 is fixedly connected to the side surface of the mounting component 201. A sliding sleeve 203 is fixedly connected to the bottom of the first extension plate 202. A permanent magnet 204 is slidably connected to the inner wall of the sliding sleeve 203. An extension rod 206 is fixedly connected to the bottom of the permanent magnet 204. A second extension plate 205 is fixedly connected to the bottom of the extension rod 206, and one side of the second extension plate 205 is fixedly connected to a limiting plate on the telescopic end of the buffer 1. A coil 207 is fixedly sleeved in the sleeve inside the sliding sleeve 203.
[0026] Switching component 3 includes a mounting plate 301. A groove 302 is formed on the top of the mounting plate 301. First electrical pieces 303 are fixedly connected to both sides of the top of the mounting plate 301, with one end of each first electrical piece 303 extending into the groove 302. A fixing rod 304 is fixedly connected to one side of the top of the mounting plate 301. A slider 305 is slidably connected within the groove 302. A rotating sleeve 306 is fixedly connected to the top of the slider 305. A second electrical piece 307 is fixedly connected to the top of the slider 305, with one end of the rotating sleeve 306 penetrating through the second electrical piece 307. A telescopic rod 308 is rotatably connected to the inner wall of the rotating sleeve 306, with one end of the telescopic rod 308 movably sleeved with… The telescopic sleeve 309 has a lever 310 fixedly connected to its other end. A spring 311 is movably sleeved on the inner wall of the telescopic sleeve 309. One end of the spring 311 abuts against one end of the telescopic rod 308, and the other end of the spring 311 abuts against one side of the inner wall of the telescopic sleeve 309. During use, when the vehicle travels over bumpy roads, the telescopic end of the buffer 1 extends and retracts with the bumps, while the permanent magnet 204 moves within the sliding sleeve 203 and cuts the coil 207 through the magnetic field, causing the coil 207 to generate an induced current. This induced current is stored in the battery through an electrically connected storage battery. When the vehicle passes through... When the performance of the buffer 1 needs to be improved on a bumpy road section, the slider 305 is moved from one side of the groove 302 to the other by moving the lever 310. At this time, one end of the telescopic rod 308 moves into the telescopic sleeve 309 and compresses the spring 311. When the slider 305 moves to the middle position of the groove 302, the telescopic rod 308 is in a vertical state and forms a 90-degree angle with the mounting plate 301, and the spring 311 is compressed to its limit. As the lever 310 continues to be moved, the telescopic rod 308 tilts in the opposite direction. At this time, the spring 311 releases potential energy, accelerating the angle change of the lever 310. At the same time, the slider 305 quickly moves closer to the other end of the groove 302 until the groove 302 is completely closed. The first electrode 303 and the second electrode 307 on one side make contact to form an electrical connection. At this time, the coil 207 forms a complete circuit through the second electrode 307 and the first electrode 303. When the telescopic end of the buffer 1 moves, the permanent magnet 204 moves inside the coil 207, which generates an induced current. Since the coil 207 is directly connected end to end and there is no load in the middle, eddy currents will appear at the same time as the induced current is generated. The eddy currents are used to resist the movement of the permanent magnet 204, thereby generating damping. This increases the damping under the original damping effect of the buffer 1, which is used to improve the damping of the buffer 1, dissipate vibration energy more quickly, reduce the system oscillation amplitude, and improve the performance of the buffer 1.
[0027] In embodiments of this utility model, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, the telescopic end of the buffer 1 is hinged to a bracket 9 via a pivot pin. A lower control arm 4 is fixedly connected to one side of the bracket 9. A ball joint 7 is movably connected to the top of the lower control arm 4. A bushing 8 is fixedly connected to the opposite side of the two ball joints 7. An upper fork arm 5 is hinged to the side surface of the other bushing 8. A connecting sleeve 6 for connecting the frame is fixedly connected to the ends of both the upper fork arm 5 and the lower control arm 4.
[0028] In embodiments of this utility model, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the positive and negative terminals of coil 207 are electrically connected to the second electrode 307 and one of the first electrodes 303. The second electrode 307 and the other first electrode 303 are connected in series with coil 207 and battery.
[0029] In embodiments of this utility model, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the limiting plate fixedly sleeved on the telescopic end of the buffer 1 is used to abut against the buffer spring on the side surface of the buffer 1.
[0030] In embodiments of this utility model, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the switching component 3 is installed in the operating chamber via the mounting plate 301, and the permanent magnet 204 generates an induced current by displacement within the sliding sleeve 203.
[0031] In embodiments of this utility model, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, one end of the telescopic sleeve 309 passes through the fixed rod 304 and is rotatably connected by a bearing. The slider 305 slides along the trajectory of the groove 302. When the telescopic end of the shock absorber (i.e., damper) in the buffer 1 moves through the electromagnetic component 2, the permanent magnet 204 moves within the coil 207, thereby generating an induced current. Depending on the requirements, this can be used to power the battery and improve the range performance, or the coil 207 can be directly connected to the first end, generating eddy currents while generating the induced current, which is used to generate damping, thereby increasing the damping coefficient and improving the shock absorption performance. Through the switching component 3, the second electrode 307 can be made to contact one of the first electrodes 303 as needed, so that the induced current in the circuit connected to the battery can be stored in the battery for battery charging, or when the second electrode 307 contacts the other first electrode 303, the coil 207 generates an induced current and eddy currents to increase the damping coefficient, which can be adjusted as needed, thereby improving the flexibility of application and expanding the range of applicable scenarios.
[0032] In embodiments of this utility model, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the spring 311 pushes against the telescopic rod 308 by applying force, and causes the second electric plate 307 on the slider 305 to abut against the first electric plate 303.
[0033] Working principle: When the vehicle is in use, when it passes through a bumpy road, the telescopic end of the buffer 1 extends and retracts with the bumps, while the permanent magnet 204 moves in the sliding sleeve 203 and cuts the coil 207 through the magnetic field, so that the coil 207 generates an induced current. The induced current is stored in the battery through the electrically connected battery.
[0034] When the performance of the buffer 1 needs to be improved after traversing a bumpy section, the lever 310 is activated, causing the slider 305 to move from one side of the groove 302 to the other. At this time, one end of the telescopic rod 308 moves into the telescopic sleeve 309 and compresses the spring 311. When the slider 305 moves to the middle position of the groove 302, the telescopic rod 308 is in a vertical state and forms a 90-degree angle with the mounting plate 301, and the spring 311 is compressed to its limit. As the lever 310 continues to be activated, the telescopic rod 308 tilts in the opposite direction. At this time, the spring 311 releases potential energy, accelerating the angle change of the lever 310. Simultaneously, the slider 305 quickly moves towards the other end of the groove 302 until the groove 302... On the other side, the first electrode 303 and the second electrode 307 make contact to form an electrical connection. At this time, the coil 207 forms a complete circuit through the second electrode 307 and the first electrode 303. When the telescopic end of the buffer 1 moves, the permanent magnet 204 moves inside the coil 207, which generates an induced current. Since the coil 207 is directly connected end to end and there is no load in the middle, eddy currents will appear at the same time as the induced current is generated. The eddy currents are used to resist the movement of the permanent magnet 204, thereby generating damping. This increases the damping under the original damping effect of the buffer 1, which is used to improve the damping of the buffer 1, dissipate vibration energy more quickly, reduce the system oscillation amplitude, and improve the performance of the buffer 1.
