Description

Technical Field

[0001] This utility model relates to the technical field of automotive buffer blocks, and in particular to an automotive spring buffer block. Background Technology

[0002] Cars inevitably experience various opening and closing collisions due to various reasons. Buffer blocks, as rubber components for shock absorption and cushioning, prevent damage to the mating parts. Existing car buffer blocks generally utilize the elasticity of rubber itself to mitigate impact. However, when subjected to external impact forces, relying solely on rubber to withstand the impact can easily lead to excessive shrinkage and deformation, potentially damaging the buffer and reducing its effectiveness. Summary of the Invention

[0003] In view of this, the purpose of this utility model is to overcome the shortcomings of the prior art and provide an automotive spring buffer block.

[0004] This utility model provides an automotive spring buffer block, including a plastic sleeve 1 and a protective sleeve 2. The protective sleeve 2 is covered with a buffer rubber head 3 that is locked onto the plastic sleeve 1. The two sides of the bottom of the protective sleeve 2 extend horizontally outward to form protrusions 2.1. A circular groove is formed at the center of the top of the plastic sleeve 1. A spring is provided between the protective sleeve 2 and the circular groove. The two sides of the circular groove are symmetrically provided with sliding grooves 1.1 to allow the protrusions 2.1 to slide into. The bottom of the circular groove is provided with an abutment groove 1.2 that communicates with the sliding groove 1.1 and allows the protrusions 2.1 to abut against it.

[0005] Furthermore, the bottom of the plastic sleeve 1 is provided with a limiting hole 1.3 that communicates with the abutment groove 1.2.

[0006] Furthermore, the bottom of the protective sleeve 2 is provided with an inner groove, and the spring is disposed between the inner groove and the circular groove. Both the circular groove and the inner groove are provided with fixing posts for accommodating the spring.

[0007] Furthermore, the outer wall of the plastic sleeve 1.1 is provided with an annular protrusion 1.4, and the inner wall of the buffer rubber head 3 is provided with a first groove for the annular protrusion 1.4 to be inserted.

[0008] Furthermore, the buffer rubber head 3 is composed of an upper corrugated section connected to a lower connecting section, and the first slot is disposed on the inner wall of the connecting section.

[0009] Furthermore, the outer wall of the connecting segment extends outward to form an annular cover.

[0010] Furthermore, the top of the protective sleeve 2 is provided with an annular locking part 2.2, and the top of the inner cavity of the buffer rubber head 3 is provided with a second slot for the annular locking part 2.2 to be engaged.

[0011] The advantages of this utility model are as follows: Buffering is achieved through a buffer rubber head and a spring. As the spring compresses, its force increases, making it difficult for the buffer rubber head to fully contract and deform. The protrusion moves up and down within the groove, limiting the rotation of the protective sleeve when the spring is under force. The buffer rubber head cushions the impact, acting on the protective sleeve and causing it to press down. The spring inside the protective sleeve provides secondary cushioning. When the buffer rubber head is impacted, it and the spring compress. The interior of the plastic sleeve and the buffer rubber head are vented to the outside through a limiting hole. The annular locking part of the protective sleeve engages with the second locking groove inside the buffer rubber head. The first locking groove of the buffer rubber head engages with the annular protrusion of the plastic sleeve. Attached Figure Description

Detailed Implementation

[0013] The present invention will now be described in detail with reference to the accompanying drawings.

[0014] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0015] See Figures 1 to 5This utility model provides an automotive spring buffer block, which includes a plastic sleeve 1 and a protective sleeve 2. The protective sleeve 2 is covered with a buffer rubber head 3 that is locked onto the plastic sleeve 1. The top of the protective sleeve 2 is provided with an annular locking part 2.2. The top of the inner cavity of the buffer rubber head 3 is provided with a second locking groove for the annular locking part 2.2 to be locked. The two sides of the bottom of the protective sleeve 2 extend horizontally outward to form protrusions 2.1. A circular groove is opened at the center of the top of the plastic sleeve 1. A spring is provided between the protective sleeve 2 and the circular groove. The two sides of the circular groove are symmetrically provided with sliding grooves 1.1 for the protrusions 2.1 to slide into. The bottom of the circular groove is provided with a stop groove 1.2 that communicates with the sliding groove 1.1 and allows the protrusions 2.1 to abut against it. The distance from the protrusion to the bottom of the circular groove is less than the distance from which the buffer rubber head contracts and deforms to the bottom. The protrusion moves up and down in the stop groove, restricting the rotation of the protective sleeve when the spring is under force. As the protrusion moves downward, the force of the spring increases, and it also rotates, making it difficult for the protrusion to disengage from the stop groove. The protrusion of the protective sleeve slides into the groove and presses down, with the protrusion positioned next to the abutment groove. Then, the plastic sleeve is rotated so that the protrusion of the protective sleeve enters the abutment groove, and the protective sleeve is released. Under the action of the spring, the protrusion rises and abuts against the top of the abutment groove. The impact is buffered by the buffer rubber head, which applies the impact to the protective sleeve, causing the protective sleeve to press down. The spring inside the protective sleeve provides secondary buffering of the impact. As the spring is compressed, the force of the spring increases, making it difficult for the buffer rubber head to contract and deform completely.

[0016] The bottom of the plastic sleeve 1 is provided with a limiting hole 1.3 that communicates with the abutment groove 1.2. When the buffer rubber head is impacted, the buffer rubber head and spring will be compressed. The inside of the plastic sleeve and the buffer rubber head is vented to the outside through the limiting hole to prevent the internal air pressure from hindering the compression of the buffer rubber head and spring.

[0017] The bottom of the protective sleeve 2 has an inner groove, and the spring is set between the inner groove and the circular groove. Both the circular groove and the inner groove are provided with fixing posts to accommodate the spring. The two fixing posts are inserted into the upper and lower ends of the spring, respectively.

[0018] See Figure 2 , Figure 4 The outer wall of the plastic sleeve 1.1 is provided with an annular protrusion 1.4, and the inner wall of the buffer rubber head 3 is provided with a first groove for the annular protrusion 1.4 to be inserted.

[0019] The buffer rubber head 3 consists of an upper corrugated section connected to a lower connecting section, with a first slot located on the inner wall of the connecting section.

[0020] The outer wall of the connecting section extends outward to form a ring-shaped cover.

[0021] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
