Description

Technical Field

[0001] This utility model relates to the field of automotive technology, specifically to a rear upper leaf spring seat. Background Technology

[0002] Leaf springs are the most widely used elastic element in automotive suspensions. They consist of several alloy spring leaves of equal width but unequal length (thickness may be equal or unequal), forming an elastic beam of approximately equal strength. Currently, the use of rear leaf spring seats has certain shortcomings; they cannot effectively provide stable support and do not reduce wear.

[0003] A patent search revealed a device, such as publication number "CN214492437U," entitled "A Comfortable Rear Leaf Spring Seat." While this device addresses the aforementioned problem, its elastic pad supports the bottom of the leaf spring. When the leaf spring deforms, the elastic pad deforms synchronously, resulting in poor shock absorption. Over time, this reduces the shock absorption effect of the elastic pad, thus lowering the overall shock absorption performance of the leaf spring. Therefore, this invention designs a rear upper leaf spring seat to solve the above problems. Utility Model Content

Detailed Implementation

[0020] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0021] Example 1 A preferred embodiment of the rear upper leaf spring seat provided by this utility model is as follows: Figures 1 to 4As shown: A rear upper leaf spring seat includes a base plate 1; a rotating plate 2 connected to the four corners of the base plate 1; a bracket 3 set at the upper end of the base plate 1, and the bracket 3 has guide grooves 4 integrally formed on the front and rear sides inside; a first self-locking bolt 5 threaded at the four corners inside the base plate 1; a first limiting rod 6 threaded through the upper end of the bracket 3, and a first self-locking nut 7 threaded at the outer rear end of the first limiting rod 6; and a shock-absorbing component 8 assembled on the outside of the base plate 1, which can buffer the vibration force received by the leaf spring placed inside the bracket 3.

[0022] The shock absorption assembly 8 includes a first shock absorption spring 801 fixed at the four corners of the top of the base plate 1, and the first shock absorption spring 801 is fixedly connected to the bracket 3; a damper 802 fixed at the middle of the top of the base plate 1, and the damper 802 is fixedly connected to the bracket 3. The first shock absorption spring 801 and the rotating plate 2 are designed to correspond to each other, and the first shock absorption spring 801 and the rotating plate 2 are offset from each other.

[0023] It should be noted that the existing rear upper leaf spring seat still has certain shortcomings in actual use. It cannot stably buffer the vibration force on the leaf spring, thus reducing the shock absorption effect of the leaf spring.

[0024] In this embodiment, the middle section of the leaf spring is first placed inside the bracket 3, and the leaf spring is welded to the bracket 3 to ensure a stable connection. Then, the first limiting rod 6 is passed through the bracket 3, and the first self-locking nut 7 is connected to the first limiting rod 6, so that the first limiting rod 6 contacts the top surface of the leaf spring, which helps to improve the stability of the connection between the bracket 3 and the leaf spring. By using the first self-locking bolt 5, the base plate 1 is fixed to the crossbeam at the bottom of the car. When the car moves, the leaf spring deforms, and the leaf spring causes the bracket 3 and the first damping spring 801 to deform, so that the first damping spring 801 buffers the vibration deformation of the leaf spring, and the damper 802 buffers the return state of the first damping spring 801.

[0025] In a further preferred embodiment of this utility model, a linkage component 9 is assembled inside the guide groove 4. The linkage component 9 increases the stability of the connection between the bracket 3 and the base plate 1. The linkage component 9 includes a slider 901 slidably disposed on the left and right sides inside the guide groove 4; and a support rod 902 fixed outside the slider 901. The support rod 902 and the rotating plate 2 are designed to correspond to each other. The end of the rotating plate 2 away from the base plate 1 is rotatably sleeved on the outside of the support rod 902.

[0026] In this embodiment, the rotating plate 2 ensures the stability of the support 3's longitudinal displacement along the base plate 1. When the steel plate spring causes the support 3 to deform along the longitudinal direction of the base plate 1, the support 3 causes the slider 901 to move along the direction of the guide groove 4, and the support rod 902 causes the rotating plate 2 to rotate, thus ensuring the stability of the support 3's displacement.

[0027] Example 2 Based on Embodiment 1, a preferred embodiment of the rear upper leaf spring seat provided by this utility model is, for example... Figures 1 to 4 As shown: Positioning components are provided on the left and right sides of the outside of the bracket 3. The positioning components can limit the two ends of the steel leaf spring. The positioning components include clamping plates 10 provided on the left and right sides of the outside of the bracket 3; a second limiting rod 11 threaded inside the upper end of the clamping plate 10; a second self-locking nut 12 threaded on the rear end of the second limiting rod 11; a second self-locking bolt 13 threaded on the front and rear sides of the top of the clamping plate 10; a first top rod 14 connected to the four corners of the outside of the bracket 3; a second top rod 15 connected to the front and rear ends of the clamping plate 10; a first reinforcing plate 16 rotatably sleeved on the outside of the first top rod 14; a second reinforcing plate 17 rotatably sleeved on the outside of the second top rod 15, and the second reinforcing plate 17 slidably sleeved on the first reinforcing plate 16; a placement plate 18 fixed on the front and rear sides of the upper end of the outside of the bracket 3; a sliding rod 19 fixed at the middle of the bottom of the placement plate 18; the sliding rod 19 passes through the bracket 3; a second shock-absorbing spring 20 fixed at the bottom of the sliding rod 19; and the end of the second shock-absorbing spring 20 away from the sliding rod 19 is fixedly connected to the base plate 1.

[0028] In this embodiment, when the leaf spring is placed inside the bracket 3, the operator inserts the left and right sides of the leaf spring into the clamping plate 10 to limit the left and right sides of the leaf spring. The operator then inserts the second limiting rod 11 into the clamping plate 10 and connects the second self-locking nut 12 to the second limiting rod 11, thereby bringing the second limiting rod 11 into contact with the top surface of the leaf spring. This auxiliaryly improves the stability of the leaf spring after it is connected to the clamping plate 10. The use of the second self-locking bolt 13 ensures a secure connection between the clamping plate 10 and the vehicle chassis. The first reinforcing plate 16 and the second reinforcing plate... 17 improves the stability of the connection between the card plate 10 and the bracket 3. When the bracket 3 vibrates along the longitudinal direction of the base plate 1, the first reinforcing plate 16 rotates around the axis of the first top rod 14, and the second reinforcing plate 17 rotates around the axis of the second top rod 15. At the same time, the first reinforcing plate 16 moves along the direction of the second reinforcing plate 17, ensuring the normality of the longitudinal displacement of the bracket 3. In addition, when the bracket 3 vibrates, the bracket 3 drives the placement plate 18 together with the slide rod 19 to squeeze the second damping spring 20 to deform, thereby making the second damping spring 20 buffer the amplitude of the vibration of the bracket 3.

[0029] In summary, this application can control the deformation vibration amplitude in the middle region of the leaf spring, improving its damping effect. The clamping plate design provides auxiliary limiting for both ends of the leaf spring, ensuring its overall stability during deformation. The bridging function design reinforces the connection between the bracket and the clamping plate using the first and second reinforcing plates, ensuring the stability of the bracket, clamping plate, and leaf spring assembly. The secondary damping function further enhances the leaf spring's damping performance.
