Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, and in particular to an automotive suspension spring assembly. Background Technology

[0002] Automotive suspension springs are elastic connecting elements between the vehicle frame (body) and the axle (or wheel). They are widely used in cars and minibuses. During vehicle operation, they need to withstand high-frequency reciprocating compression motion, which can mitigate the impact force on the vehicle during driving and ensure the safety and comfort of the occupants.

[0003] In the existing technology, when a car is in motion, the suspension will oscillate in multiple directions with the steering and bumps, which will restrict the normal movement of the suspension and affect the cushioning adaptability of the suspension. At the same time, the springs are easily damaged by impacts from foreign objects such as stones and mud. The lack of protective structure to protect the surface of the springs affects the structural strength of the springs and increases the safety hazard of spring breakage. Utility Model Content

[0004] The purpose of this utility model is to solve the problems in the existing technology where the suspension of a car will swing in multiple directions during driving conditions such as steering and bumps, which will restrict the normal movement of the suspension. At the same time, the springs are easily damaged by impacts from foreign objects such as stones and mud, and there is a lack of protective structure to protect the spring surface. Therefore, a car suspension spring assembly is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an automotive suspension spring assembly, including mounting seats, two mounting seats are provided, and a protective mechanism is installed between the two mounting seats. The protective mechanism includes mounting sections, one end of each mounting section is rotatably connected to one end of each of the two mounting seats, one end of one mounting section is fixedly connected to a first protective cover, and one end of the other mounting section is fixedly connected to a second protective cover. An inner positioning protective cover is fixedly connected to the inner ring surface of the second protective cover, and the other end of the first protective cover is slidably connected between the outer surface of the inner positioning protective cover and the inner ring surface of the second protective cover. A spring buffer mechanism is installed between the two mounting sections.

[0006] Preferably, both the first and second protective covers have perforated grooves on their side walls.

[0007] Preferably, a rubber buffer pad is fixedly connected to the outer surface of the inner positioning protective cover, and the other end of the first protective cover overlaps with one end of the rubber buffer pad.

[0008] Preferably, the spring buffer mechanism includes a connecting rod and a sleeve. One end of the connecting rod is fixedly connected to one end of one of the mounting sections, and one end of the sleeve is fixedly connected to one end of the other mounting section. A main spring is sleeved on the outside of both the connecting rod and the sleeve, and the main spring is installed between the two mounting sections.

[0009] Preferably, the sleeve has a fixed cavity inside, and a sliding block is slidably connected to the inner wall of the fixed cavity. One end of the sliding block is fixedly connected to the other end of the connecting rod.

[0010] Preferably, a sealing ring is fixedly connected to the other end of the sleeve, and the sealing ring is slidably sleeved on the outside of the connecting rod.

[0011] Preferably, a fixing block is fixedly connected to the inner side of the fixed cavity, and an auxiliary spring is installed between the fixing block and the sliding block.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows: 1. In this utility model, when the car suspension drives the two mounting seats to move closer or further apart, the two mounting sections move synchronously. The first protective cover slides along the gap between the outer surface of the inner positioning protective cover and the inner ring surface of the second protective cover. The rubber buffer pad will buffer the impact at its sliding end. The telescopic structure composed of the first protective cover, the inner positioning protective cover and the second protective cover can prevent foreign objects such as stones and mud from contacting the spring buffer mechanism. At the same time, it constrains the deformation direction of the spring, avoids uneven wear and misalignment of the spring, and extends the service life of the spring. The hollow groove realizes ventilation and drainage inside the protective mechanism, reduces the risk of corrosion and damage to the spring buffer mechanism, and enhances the protective performance and stability of the suspension spring assembly.

[0013] 2. In this utility model, when the car suspension drives the mounting seat to make the two mounting sections move relative to each other, the main spring is compressed or rebounded synchronously with the relative displacement of the connecting rod and the sleeve. At the same time, the connecting rod drives the sliding block to slide in the fixed cavity, so that the auxiliary spring generates elastic deformation synchronously. The sealing ring at the end of the sleeve prevents dust and moisture from entering the fixed cavity. The double elastic buffering of the main spring and the auxiliary spring enhances the shock absorption effect of the suspension and improves the uniformity of the buffering.

[0016] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0017] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0018] Example 1: As Figures 1-4 As shown, this utility model provides an automotive suspension spring assembly, including a mounting base 1. Two mounting bases 1 are provided, and a protective mechanism 2 is installed between the two mounting bases 1. The protective mechanism 2 includes mounting sections 21. One end of each mounting section 21 is rotatably connected to one end of each of the two mounting bases 1. One end of one mounting section 21 is fixedly connected to a first protective cover 22, and one end of the other mounting section 21 is fixedly connected to a second protective cover 25. An inner positioning protective cover 23 is fixedly connected to the inner ring surface of the second protective cover 25. The other end of the first protective cover 22 is slidably connected between the outer surface of the inner positioning protective cover 23 and the inner ring surface of the second protective cover 25. A spring buffer mechanism 3 is installed between the two mounting sections 21. Hollow grooves 26 are provided on the side walls of both the first protective cover 22 and the second protective cover 25. A rubber buffer pad 24 is fixedly connected to the outer surface of the inner positioning protective cover 23, and the other end of the first protective cover 22 overlaps with one end of the rubber buffer pad 24.

[0019] When the car encounters bumpy road surfaces, the suspension moves up and down, causing the two mounting seats 1 to move closer or further apart, which in turn causes the two mounting sections 21 to move synchronously relative to each other. The protective mechanism 2 moves with the mounting section 21. The first protective cover 22 slides along the gap between the outer surface of the inner positioning protective cover 23 and the inner ring surface of the second protective cover 25, realizing the extension and retraction of the protective mechanism 2. The rubber buffer pad 24 will buffer the end impact when the first protective cover 22 slides, reducing collision noise. The spring buffer mechanism 3 undergoes elastic deformation synchronously to buffer the road bumps. The first protective cover 22 and the second protective cover 25 prevent foreign objects from contacting the spring buffer mechanism 3, reducing the risk of spring corrosion and damage. The hollow groove 26 realizes ventilation and drainage inside the protective mechanism 2.

[0020] Example 2: Figure 1 and Figure 2 As shown, the spring buffer mechanism 3 includes a connecting rod 31 and a sleeve 33. One end of the connecting rod 31 is fixedly connected to one end of one of the mounting sections 21, and one end of the sleeve 33 is fixedly connected to one end of the other mounting section 21. A main spring 32 is sleeved on the outside of the connecting rod 31 and the sleeve 33, and the main spring 32 is installed between the two mounting sections 21. A fixed cavity 38 is provided inside the sleeve 33. A sliding block 34 is slidably connected to the inner wall of the fixed cavity 38. One end of the sliding block 34 is fixedly connected to the other end of the connecting rod 31. A sealing ring 35 is fixedly connected to the other end of the sleeve 33, and the sealing ring 35 is slidably sleeved on the outside of the connecting rod 31. A fixing block 37 is fixedly connected to the inside of the fixed cavity 38, and an auxiliary spring 36 is installed between the fixing block 37 and the sliding block 34.

[0021] When the car suspension moves the two mounting seats 1 closer together, the two mounting sections 21 move closer together simultaneously. The main spring 32 is compressed, generating elastic force to buffer road bumps. The connecting rod 31 moves with the mounting section 21, causing the sliding block 34 to slide within the fixed cavity 38 of the sleeve 33, compressing the auxiliary spring 36. The auxiliary spring 36 generates additional elastic force, enhancing the buffering effect. When the suspension moves the two mounting seats 1 away from each other, the main spring 32 rebounds and extends, and the auxiliary spring 36 rebounds simultaneously, pushing the sliding block 34 back to its original position. This, in turn, causes the connecting rod 31 to move synchronously. The dual elastic buffering of the main spring 32 and the auxiliary spring 36 improves the shock absorption effect and ride comfort of the suspension. The sealing ring 35 prevents dust and moisture from entering the fixed cavity 38, avoiding jamming or corrosion of the sliding block 34 and the auxiliary spring 36.

[0022] The usage and working principle of this device are as follows: When a car encounters a bumpy road, the impact is transmitted to the car suspension, causing the two mounting seats 1 to move closer or further apart. The two mounting sections 21, which are rotatably connected to the mounting seats 1, move synchronously with the mounting seats 1. The first protective cover 22 slides along the gap between the outer surface of the inner positioning protective cover 23 and the inner ring surface of the second protective cover 25. The rubber buffer pad 24 buffers the sliding impact. At the same time, the first protective cover 22, the inner positioning protective cover 23 and the second protective cover 25 together form a barrier to prevent foreign objects from contacting the internal spring buffer mechanism 3. The main spring 32 is compressed or rebounded outside the connecting rod 31 and the sleeve 33 with the relative movement of the two mounting sections 21, generating elastic force to buffer the bumps. The connecting rod 31 also drives the sliding block 34 to slide in the fixed cavity 38, causing the auxiliary spring 36 to deform synchronously, further enhancing the buffering effect. The sealing ring 35 at the end of the sleeve 33 prevents dust and moisture from entering the fixed cavity 38, avoiding jamming or corrosion of internal components.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
