Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of automobile opening and closing parts, more particularly to a lateral buffer device. BACKGROUND

[0002] In modern automobile design, buffer blocks, as a key shock-absorbing component, are widely used in the structures of opening and closing parts such as tailgates, trunks, doors, and engine covers, playing a crucial role. They reduce the overtravel of opening and closing parts during closure, prevent parts from colliding, and protect the appearance and internal components of the vehicle from damage. In addition, automobile buffer blocks can effectively reduce the impact force transmitted by bumpy roads during driving, improve the noise, vibration, and harshness (NVH) performance of the vehicle, and thus enhance overall driving comfort. To meet different usage requirements, buffer blocks are usually made of rubber, plastic, metal, or rubber and metal composites, and different combinations of these materials endow buffer blocks with good shock-absorbing, durability, and stability.

[0003] The automobile buffer blocks in the prior art achieve the buffering effect by directly contacting the entire surface of the sliding part with the buffer block. Specifically, when the opening and closing part is closed, the sliding part contacts the surface of the buffer block, and the reaction force of the buffer block pushes the sliding part and the fixed part to move relatively, thereby achieving adaptive adjustment and ensuring that the buffer block always remains in contact to achieve the shock-absorbing purpose. However, in actual production, due to errors in vehicle body processing, the entire surface of the sliding part may not be in full contact with the surface of the buffer block, which may cause the buffer effect to be reduced, and in extreme cases, the buffer block may fail to effectively perform its intended shock-absorbing function. SUMMARY

[0004] The utility model aims at solving one of the technical problems in the related art to some extent. To this end, the utility model embodiment proposes a lateral buffer device, which sets an upper cover above the product surface on the surface of the sliding part and utilizes the interference between the upper cover, the rubber block, and the inclined surface. This design ensures stable and reliable buffer effect, solves the problem of incomplete contact caused by processing errors, and improves the adaptability and durability of the shock-absorbing system.

[0005] The technical solution adopted by the utility model is to provide a lateral buffer device, which includes a vehicle body side buffer block and an opening and closing part side buffer block. The vehicle body side buffer block includes a sliding part and a fixed part, and the opening and closing part side buffer block includes a rubber buffer block. The sliding part is connected with an upper cover, and the upper cover protrudes from the surface of the sliding part. When the opening and closing part is closed, the upper cover contacts the rubber buffer block. When the pressure of the rubber buffer block on the sliding part is greater than the resistance of the fixed part, the sliding part slides relative to the fixed part.

[0006] With the above structure, the upper cover is arranged on the surface of the sliding part and protrudes from the surface of the sliding part, and when the opening and closing part is closed, the upper cover contacts the rubber buffer block, and further generates effective reaction force to push the relative movement between the sliding part and the fixed part. It is particularly worth noting that the upper cover of the utility model is higher than the product surface, and after being pressed again, the upper rubber block interferes with the lower product inclined surface, thereby forming a buffering effect. This innovative design solves the problem of incomplete contact between the sliding part and the buffer block caused by processing errors in traditional technology, and ensures the stability and reliability of the buffering effect.

[0007] Specifically, in the traditional design, when the surfaces of the sliding part and the buffer block do not fully contact, the avoidance phenomenon easily occurs, resulting in reduced or ineffective buffering effect. However, through the protruding structure of the upper cover, the utility model ensures full contact between the sliding part and the buffer block, and even in the presence of certain processing errors, effective shock absorption can still be achieved. When the upper cover is pressed down, the upper rubber block interferes with the lower inclined surface, and through this interference force, a natural buffering effect is formed, effectively avoiding the incomplete contact problem in traditional technology. This design ensures that the buffer block maintains high-efficiency shock absorption throughout the entire closing process, not only enhancing the adaptability of the shock absorption system, but also improving the durability and stability of the system.

[0008] According to one embodiment of the utility model, the sliding part is provided with an opening, and the upper cover covers the opening.

[0009] According to one embodiment of the utility model, the upper cover protrudes from the sliding part by 0.5-1.5 mm.

[0011] According to one embodiment of the utility model, the sliding block is a dovetail block, and the sliding groove is a dovetail groove; the dovetail block is wedge-shaped and can tightly cooperate with the dovetail groove; and / or

[0012] The sliding groove has a positioning groove at the bottom, and the sliding block has a positioning protrusion at the position corresponding to the positioning groove, which can slidably cooperate with the positioning groove.

[0013] According to one embodiment of the utility model, the sliding block is provided with a toothed surface, and the sliding groove has a toothed step at the position corresponding to the toothed surface; the toothed surface contacts the toothed step, thereby increasing the friction between the sliding block and the sliding groove to increase the resistance between the sliding part and the fixed part.
