Novel structure of automobile lock head shaft cover

Abstract

This utility model discloses a novel structure for an automotive latch head axle cover, comprising a body with grooves on both sides of its interior. Multiple sliding grooves are formed on both sides of each groove, and a movable plate is movably fitted inside each sliding groove. A first spring is fixedly installed between one side of the movable plate and one side of the sliding groove. Through this structure, when an impact force is transmitted to the axle cover, the sliding limiting structure formed by the sliding grooves on both sides of the groove inside the body and the movable plate, combined with the elastic buffering of the first spring, allows the movable plate to slide along the sliding groove and compress the first spring at the moment of impact, converting the impact force into the elastic potential energy of the spring. This effectively weakens the impact on the fixed structure. Simultaneously, the inclined plate and the pressing plate on one side of the movable plate work together, and the arc-shaped groove and anti-slip texture on the pressing plate side can tightly fit the rivet components, further enhancing friction under impact force and ensuring that the axle cover is not easily displaced under stress.

Description

Technical Field

[0001] This utility model relates to the field of automotive latch head shaft cover technology, and in particular to a novel structure for automotive latch head shaft cover. Background Technology

[0002] The vehicle lock latch head axle cover serves to cover and protect the axle head, preventing external impurities such as dust, dirt, and water from entering the axle head. This avoids these impurities causing wear, corrosion, or blockage to key components such as bearings and gears, thereby extending the service life of internal components and ensuring the normal operation of the vehicle's transmission system.

[0003] In the prior art, such as the novel structure of the automotive latch head axle cover proposed in patent 201420333878.2, the product structure of the automotive latch head axle cover is improved while ensuring its function, which can achieve the purpose of preventing rivet loosening. At the same time, the use of simple riveting and riveting molds to quickly rivet the rivets to the automotive latch head axle cover improves production efficiency. However, when the car encounters large potholes or bumps while driving, a large impact force will be generated. When these impact forces are transmitted to the car lock part, the axle cover may be subjected to a large external force at one moment, which may make the axle cover not secure and easy to loosen. Therefore, in order to solve this problem, we propose a novel structure for the automotive latch head axle cover. Utility Model Content

[0004] The purpose of this utility model is to provide a new structure for automotive latch head axle caps. The arc-shaped groove and anti-slip texture on one side of the extrusion plate can tightly fit the rivet components and further enhance the friction under impact force, ensuring that the axle cap is not easily displaced when under force. In addition, the feed pipe can regularly replenish lubricant to maintain lubrication performance and ensure the long-term stable operation of each component.

[0005] To achieve the above objectives, a novel structure for an automotive latch head cover is provided, comprising a body. Grooves are formed on both sides of the interior of the body. Multiple sliding grooves are formed on both sides of the interior of each groove. Movable plates are movably fitted inside each sliding groove. A first spring is fixedly installed between one side of the movable plate and one side of the sliding groove. An inclined plate is fixedly installed on one side of the movable plate, and a pressing plate is fixedly installed on one side of the inclined plate. A sleeve is provided on the exterior of the body. Two chambers are formed inside the body. Lubricant is provided inside each chamber. Multiple support cylinders are fixedly installed inside each chamber. Multiple first through holes are formed inside each support cylinder. A second spring is fixedly installed inside each support cylinder. A movable cylinder is fixedly installed at one end of the second spring. Multiple second through holes are formed inside each movable cylinder. A micro-hole is formed at the front end of the movable cylinder. A feed pipe is fixedly installed on the top of the body.

[0006] According to the novel structure of the automotive latch head cover, the outer surface of the body is provided with threads, and the inner wall of the sleeve is provided with a matching internal thread hole. The body engages with the internal thread hole of the sleeve using the threads.

[0007] According to the novel structure of the automotive latch head cover, one side of the extrusion plate is recessed inward to form an arc-shaped groove, and the inner wall of the arc-shaped groove of the extrusion plate is provided with anti-slip texture.

[0008] According to the novel structure of the automotive latch head cover, the movable cylinder is disposed inside the support cylinder, and the support cylinder limits the movement of the movable cylinder.

[0009] According to the novel structure of the automotive latch head cover, the movable plate can slide inside the slide groove, while the slide groove limits the movement of the movable plate.

[0010] According to the novel structure of the automotive latch head cover, the groove is rectangular in shape, and the width of the groove is adapted to the thickness of the inclined plate.

[0011] According to the novel structure of the automotive latch head cover, there are four sliding grooves, which are symmetrically distributed on both sides of the inner side of the groove.

[0012] According to the novel structure of the automotive latch head cover, the top of the feed tube is provided with a sealing cover, and the sealing cover is connected to the feed tube by a thread.

[0013] Beneficial effects:

[0014] 1. When the impact force is transmitted to the shaft cover, the sliding limit structure formed by the sliding grooves on both sides of the groove inside the machine body and the movable plate, together with the elastic buffer of the first spring, allows the movable plate to slide along the sliding groove and compress the first spring at the moment of impact, converting the impact force into the elastic potential energy of the spring, effectively weakening the impact on the fixed structure. At the same time, the inclined plate on one side of the movable plate and the extrusion plate work together, and the arc groove and anti-slip texture on the extrusion plate can closely fit the rivet parts, further enhancing the friction under the action of the impact force, ensuring that the shaft cover is not easy to displace when subjected to force.

[0015] 2. During use, the second spring provides elastic support. When the movable cylinder compresses the second spring inside the support cylinder, the lubricant flows through the first through hole, the second through hole, and the micropores to reduce friction and wear between components. In addition, the feed pipe can replenish the lubricant periodically to maintain lubrication performance and ensure the long-term stable operation of each component.

[0025] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0026] Reference Figure 1-5This utility model discloses a novel structure for an automotive latch head axle cover, comprising a body 1, which is the core load-bearing component of the entire axle cover, facilitating installation. Grooves 2 are provided on both sides of the interior of the body 1, providing stable space for the inclined plate 15. Multiple sliding grooves 3 are provided on both sides of the interior of the grooves 2, ensuring smooth sliding of the movable plate 4. Movable plates 4 are movably fitted inside each of the sliding grooves 3, with the width of the movable plate 4 slightly smaller than the width of the sliding groove 3, ensuring flexibility while preventing wobbling within the sliding groove 3. A first spring 5 is fixedly installed between one side of the movable plate 4 and one side of the sliding groove 3, providing appropriate rebound force to the movable plate 4. An inclined plate 15 is fixedly installed on one side of the movable plate 4, effectively transmitting force to the pressing plate 6 when subjected to external force. The pressing plate 6 is also fixedly installed on one side of the inclined plate 15, tightly fitting the rivet. A sleeve 7 is provided on the exterior of the body 1. External force can be provided to the inclined plate 15. The body 1 has two chambers inside, each containing lubricant. Multiple support cylinders 8 are fixedly installed inside the chambers of the body 1, facilitating the movement of the movable cylinder 11. Multiple first through holes 9 are provided inside the support cylinders 8, allowing the lubricant to pass smoothly through. A second spring 10 is fixedly installed inside the support cylinder 8, providing a suitable rebound force to the movable cylinder 11. One of the second springs 10... A movable cylinder 11 is fixedly installed at one end, which allows for better and more convenient lubrication of the components. The movable cylinder 11 has multiple second through holes 12 inside, which correspond to the first through holes 9 to facilitate the flow of lubricant. The front end of the movable cylinder 11 has micro-holes 13. The micro-holes 13 have extremely small diameters, which allow the lubricant to be sprayed evenly onto the components in the form of fine particles. A feed pipe 14 is fixedly installed on the top of the machine body 1, which allows the lubricant to be placed in the internal cavity of the machine body 1.

[0027] Specifically: The outer surface of the body 1 is provided with threads, and the inner wall of the sleeve 7 is provided with a matching internal thread hole. The body 1 uses the threads to engage with the internal thread hole of the sleeve 7. The threaded connection method achieved by the body 1 using the threads to engage with the internal thread hole of the sleeve 7 not only makes installation and disassembly convenient, but also ensures the firmness of the connection between the sleeve 7 and the body 1.

[0028] Specifically: One side of the extrusion plate 6 is recessed inward to form an arc-shaped groove. The inner wall of the arc-shaped groove of the extrusion plate 6 is provided with anti-slip texture. The anti-slip texture on one side of the extrusion plate 6 increases the friction between the extrusion plate 6 and the rivet, preventing loosening during use.

[0029] Specifically: The movable cylinder 11 is located inside the support cylinder 8, and the support cylinder 8 limits its movement. The support cylinder 8 limits the movable cylinder 11 to ensure that the movable cylinder 11 can only move axially inside the support cylinder 8.

[0030] Specifically: the movable plate 4 can slide inside the slide groove 3, and the slide groove 3 limits the movable plate 4. By using the slide groove 3 to limit the movable plate 4, excessive movement of the movable plate 4 can be prevented.

[0031] Specifically, the groove 2 is rectangular in shape, and the width of the groove 2 is adapted to the thickness of the inclined plate 15, which facilitates the movement of the inclined plate 15.

[0032] Specifically: There are four slide grooves 3, which are symmetrically distributed on both sides of the inside of the groove 2. The slide grooves 3 can be used to easily fit the movable plate 4, making it easy to move.

[0033] Specifically: The top of the feed pipe 14 is provided with a sealing cap, and the sealing cap is connected to the feed pipe 14 by a thread, so as to prevent lubricant leakage.

[0034] Working principle: When the shaft cover is subjected to external impact, the sliding grooves 3 on both sides of the groove 2 and the movable plate 4 form a sliding limiting structure. Under the action of the impact force, the movable plate 4 slides along the sliding groove 3, compressing the first spring 5, converting the impact energy into the elastic potential energy of the spring, effectively weakening the impact on the fixed structure. At the same time, the sleeve 7 is used to push the extrusion plate 6 on one side of the movable plate 4 with the inclined plate 15. The arc groove and anti-slip texture on one side of the extrusion plate 6 are tightly attached to the rivet parts, increasing the friction force to prevent the shaft cover from being displaced by force and improving the structural stability. Meanwhile, the lubricant stored in the internal cavity of the machine body 1 provides elastic support to the movable cylinder 11 through the second spring 10. When the parts vibrate or are subjected to force during operation, the movable cylinder 11 compresses the second spring 10 in the support cylinder 8. At this time, the lubricant seeps out in sequence through the first through hole 9, the second through hole 12 and the micropore 13, accurately covering the key friction parts and reducing wear between parts. In addition, the feed pipe 14 can replenish the lubricant periodically. With the sealing design of the top sealing cover, the lubrication system is ensured to operate stably for a long time and the reliable operation of each part of the shaft cover is guaranteed.

[0035] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
