Description
Technical Field
[0001] The present application relates to the technical field of buffer devices, and in particular to a suspension buffer device for a car model. Background Art
[0002] As an important component of the vehicle suspension system, the performance of the car model suspension type buffer device directly affects the ride comfort and driving stability of the vehicle. However, during long-term use, the existing car model suspension type buffer device often changes in buffering performance.
[0003] Currently, a significant problem with existing suspension damping systems for model cars is that once their performance changes, it's often difficult for users to effectively adjust them. For example, on uneven roads, a stronger damping force may be needed to absorb impact, while on smooth roads, a weaker force may be needed to maintain vehicle stability and maneuverability. However, existing damping systems lack the flexibility to adapt to these actual needs, limiting the vehicle's adaptability and the driver's experience.
[0004] Therefore, the present application provides a car model suspension type buffer device to solve the above problems. Utility Model Content
[0005] The present application provides a car model suspension buffer device, which aims to solve the problem that the existing buffer device proposed in the background technology cannot be flexibly adjusted according to these actual needs, thereby limiting the adaptability of the vehicle and the driver's experience.
[0006] To achieve the above-mentioned objectives, the present application provides the following technical solutions: a suspension-type buffer device for a car model, comprising a fixed sleeve, a movable sleeve sleeved on the fixed sleeve, a guide rod slidably plugged into the lower end of the fixed sleeve and connected to the wheel, a fixed sleeve sleeved on the guide rod, and a buffer spring sleeved on the fixed sleeve and the guide rod, corresponding to the movable sleeve sleeve and the fixed sleeve sleeve;
[0007] To facilitate adjustment of the buffering force of the buffer device, an adjustment structure for adjusting the buffering force of the buffer device is provided within the fixed sleeve. The adjustment structure includes an adjustment plate slidably disposed within the fixed sleeve, a damping spring disposed within the fixed sleeve corresponding to the upper end of the adjustment plate, and a drive member disposed within the guide rod for driving the adjustment plate upward and downward. When the wheel moves up and down, the guide rod slides within the fixed sleeve. At this time, the buffering spring is compressed or stretched, providing a buffering force. To adjust the buffering force, the adjustment plate is moved upward and downward within the fixed sleeve by the drive member. When the adjustment plate rises, the damping spring is further compressed, increasing the elastic force, thereby increasing the resistance to the guide rod's sliding and ascending movement within the fixed sleeve, thereby increasing the buffering force of the buffer device. Conversely, when the adjustment plate descends, the compression of the damping spring decreases, reducing the elastic force, thereby reducing the buffering force of the buffer device.
[0008] Preferably, to ensure the stability of the adjustment plate's position after adjustment, the drive member includes an internally threaded sleeve slidably inserted into the top of the guide rod and fixedly connected to the lower end of the adjustment plate, a drive screw inserted into the bottom of the internally threaded sleeve and rotationally connected to the bottom of the guide rod, and a drive toothed plate fixedly sleeved onto the bottom of the drive screw. The threaded engagement between the drive screw and the internally threaded sleeve allows the adjustment plate to maintain a stable position after adjustment and is less susceptible to displacement due to external factors (such as vibration, impact, etc.).
[0009] Preferably, the internally threaded sleeve is prevented from circumferential rotation by the cooperation of the limiting groove and the limiting rod. The driving member further includes a plurality of limiting rods equidistantly fixed to the internally threaded sleeve in an annular array, and limiting grooves defined in the guide rod, into which the limiting rods are inserted. The cooperation between the limiting rods and the limiting grooves effectively prevents circumferential rotation of the internally threaded sleeve during the raising and lowering process, ensuring stable raising and lowering of the adjustment plate and accurate adjustment of the buffering force.
[0010] Preferably, to facilitate adjustment of the elastic force of the buffer spring, the fixed sleeve is provided with an external thread, and the movable sleeve is threadably mounted on the fixed sleeve. By rotating the movable sleeve, the distance between the movable sleeve and the fixed sleeve can be changed, thereby adjusting the preload and elastic force of the buffer spring.
[0011] Preferably, in order to increase the friction between the movable cover and the hand: a plurality of protruding rods are fixedly connected to the outer wall of the movable cover in an annular array. The design of the protruding rods increases the contact area between the hand and the movable cover, making the grip more comfortable and reducing hand fatigue during long-term operation.
[0012] Preferably, to prevent the guide rod from dislodging from the fixed sleeve, a limit collar is slidably disposed within the fixed sleeve, the limit collar being fixedly mounted on the top of the guide rod. The presence of the limit collar provides a stable support point for the guide rod, preventing it from sliding upward out of the fixed sleeve due to external forces during adjustment, thereby enhancing the structural stability of the entire buffer device.
[0013] Preferably, to facilitate installation of the buffer device, the upper end of the fixed sleeve and the lower end of the guide rod are fixedly connected to a connecting seat, and a through hole is formed on the connecting seat. The design of the connecting seat and the through hole makes the installation process of the buffer device simpler and faster.
[0014] By raising and lowering the adjustment plate via a driver, the damping spring force can be adjusted, thereby conveniently adjusting the buffering force of the buffer device. This allows for flexible adjustment of the buffering force based on vehicle needs and road conditions, improving the adaptability of the vehicle's suspension system and the driver's experience. The adjustment mechanism is housed within the fixed sleeve, eliminating the need for additional space and ensuring a compact and aesthetically pleasing structure. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.
[0021] This embodiment provides a car model suspension type buffer device, such as Figure 1-3 As shown, the buffer device includes a fixed sleeve 1, a movable sleeve plate 2 sleeved on the fixed sleeve 1, a guide rod 3 slidably inserted at the lower end of the fixed sleeve 1 and connected to the wheel, a fixed sleeve plate 4 fixedly sleeved on the guide rod 3, and a buffer spring 5 sleeved on the fixed sleeve 1 and the guide rod 3, corresponding to the movable sleeve plate 2 and the fixed sleeve plate 4;
[0022] To facilitate adjustment of the buffering force of the buffer device, an adjustment structure 6 for adjusting the buffering force is located within the fixed sleeve 1. This adjustment structure 6 comprises an adjustment plate 61 slidably mounted within the fixed sleeve 1, a damping spring 62 mounted within the fixed sleeve 1 corresponding to the upper end of the adjustment plate 61, and a driver 63 mounted within the guide rod 3 to drive the adjustment plate 61 upward and downward. By driving the adjustment plate 61 upward and downward, the elastic force of the damping spring 62 can be adjusted, thereby conveniently adjusting the buffering force of the buffer device. This allows for flexible adjustment of the buffering force according to the vehicle's needs and road conditions, improving the vehicle's suspension system's adaptability and the driver's experience. The adjustment structure 6 is located within the fixed sleeve 1, eliminating the need for additional space and making the entire buffer device compact and aesthetically pleasing. When the wheel moves up and down, the guide rod 3 slides within the fixed sleeve 1. This causes the buffering spring 5 to be compressed or stretched, providing the buffering force. To adjust the buffering force, the driver 63 drives the adjustment plate 61 upward and downward within the fixed sleeve 1. When the adjustment plate 61 rises, the damping spring 62 is further compressed, increasing its elastic force, thereby increasing the resistance to the sliding and ascending movement of the guide rod 3 within the fixed sleeve 1, thereby increasing the buffering force of the buffer device. Conversely, when the adjustment plate 61 descends, the compression of the damping spring 62 decreases, reducing its elastic force, thereby reducing the buffering force of the buffer device.
[0023] Specifically, to ensure the stability of the position of the adjustment plate 61 after adjustment, the drive member 63 includes an internally threaded sleeve 631 that is slidably plugged into the top of the guide rod 3 and fixedly connected to the lower end of the adjustment plate 61, a drive screw 632 that is plugged into the bottom of the internally threaded sleeve 631 and rotatably connected to the bottom of the guide rod 3, and a drive tooth plate 633 that is fixedly sleeved on the bottom of the drive screw 632. Through the threaded engagement between the drive screw 632 and the internally threaded sleeve 631, the adjustment plate 61 can maintain a stable position after adjustment and is not easily displaced by external factors (such as vibration, impact, etc.). Because the threaded engagement has a self-locking property, the adjustment plate 61 can maintain a high degree of accuracy during the adjustment process, making the adjustment of the buffering force more accurate. When the buffering force needs to be adjusted, the drive tooth plate 633 is first connected by rotating and applying a rotational torque. The drive tooth plate 633 drives the drive screw 632 to rotate. Due to the threaded engagement between the drive screw 632 and the internally threaded sleeve 631, the internally threaded sleeve 631 will move up and down along the guide rod 3, thereby driving the adjustment plate 61 to rise and fall. The lifting and lowering motion of the adjustment plate 61 changes the degree of compression of the damping spring 62, thereby adjusting its elastic force. When the adjustment plate 61 rises, the damping spring 62 is further compressed, increasing its elastic force; conversely, when the adjustment plate 61 descends, the degree of compression of the damping spring 62 decreases, reducing its elastic force.
[0024] More specifically, the cooperation between the limiting grooves 635 and the limiting rods 634 prevents circumferential rotation of the internally threaded sleeve 631. The driver 63 also includes a plurality of limiting rods 634 equidistantly fixed to the internally threaded sleeve 631 in an annular array, as well as limiting grooves 635 formed on the guide rod 3. The limiting rods 634 engage within the limiting grooves 635. The cooperation between the limiting rods 634 and the limiting grooves 635 effectively prevents circumferential rotation of the internally threaded sleeve 631 during the raising and lowering process, ensuring stable raising and lowering of the adjustment plate 61 and accurate adjustment of the buffering force. Since the internally threaded sleeve 631 is prevented from circumferential rotation, the raising and lowering motion of the adjustment plate 61 is smoother and more accurate, thereby improving the accuracy of buffering force adjustment. When the buffering force needs to be adjusted, the external drive device rotates the drive screw 632 via the drive gear plate 633. Due to the threaded engagement between the internally threaded sleeve 631 and the drive screw 632, the internally threaded sleeve 631 will rise and fall along the guide rod 3. During this process, the limiting rod 634 slides along the limiting groove 635 and is constrained by the limiting groove 635 and cannot drive the internal threaded sleeve 631 to rotate circumferentially.
[0025] Specifically, to facilitate adjustment of the spring force of the buffer spring 5, the fixed sleeve 1 is provided with external threads 11, and the movable sleeve 2 is threadedly mounted on the fixed sleeve 1. By rotating the movable sleeve 2, the distance between it and the fixed sleeve 4 can be changed, thereby adjusting the preload and spring force of the buffer spring 5. This design allows the buffering force of the buffer device to be flexibly adjusted according to actual needs, improving the device's adaptability and practicality.
[0026] More specifically, to increase friction between the movable plate 2 and the hand, a number of protruding rods 21 are fixedly connected to the outer wall of the movable plate 2 in a circular array. These rods 21 increase the contact area between the hand and the movable plate 2, making grip more comfortable and reducing hand fatigue during prolonged operation. The presence of these rods 21 increases friction between the hand and the movable plate 2, allowing the user to rotate the movable plate 2 more stably and preventing inaccurate adjustments caused by slipping or sliding.
[0027] Specifically, to prevent the guide rod 3 from escaping from the fixed sleeve 1, a limit collar 31 is provided within the fixed sleeve 1 for sliding movement. The limit collar 31 is fixedly mounted on the top of the guide rod 3. The presence of the limit collar 31 provides a stable support point for the guide rod 3, preventing it from sliding upward out of the fixed sleeve 1 due to external forces during adjustment, thereby enhancing the structural stability of the entire buffer device.
[0028] Specifically, to facilitate installation of the buffer device, a connecting base 7 is fixedly connected to the upper end of the fixed sleeve 1 and the lower end of the guide rod 3. Connecting base 7 is provided with a through hole 71. The design of connecting base 7 and through hole 71 makes installation of the buffer device simpler and faster. The user simply inserts the fastener through through hole 71 and connects it to the mounting bracket or fixed structure, eliminating the need for complex positioning or alignment.
[0029] The above is only a preferred specific implementation method of the present application, but the scope of protection of the present application is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes based on the technical solution and concept of the present application within the technical scope disclosed in the present application, and they should be covered by the scope of protection of the present application.
