Description

Technical Field

[0001] This utility model relates to the field of spring buffer technology, and more specifically to a spring buffer assembly for a car door lock. Background Technology

[0002] With the development of the automotive industry, the functions and types of car door lock systems are becoming increasingly diverse. Passengers have higher and higher requirements for the safety, comfort and service life of cars. Traditional car door lock structures often generate a large impact force when closing the door, which not only affects the comfort of passengers, but may also damage the door and body.

[0003] The weight of a car door varies depending on the model and configuration. Existing buffer components cannot adjust the buffering force and have a single buffering method, which makes it impossible to effectively control the impact force when the car door closes. The car door lock will be frequently subjected to large impact forces, which will lead to accelerated wear of the internal parts of the car door lock and shorten the service life of the car door lock. When the components are damaged, maintenance and replacement are also quite complicated. Utility Model Content

[0018] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The spring buffer assembly of the car door lock involved in this utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0019] Reference Figure 1-6 This utility model provides a spring buffer assembly for a car door lock, including a lock body assembly 1, an installation assembly 2 sleeved on the right side of the lock body assembly 1, a main buffer assembly 3 sleeved inside the installation assembly 2, and a secondary buffer assembly 4 disposed outside the installation assembly 2 and the main buffer assembly 3. Reference Figure 1-3 The lock body assembly 1 includes a door lock 101, a lock hole 102, and a connector 103, wherein the lock hole 102 is located on the left side of the door lock 101, and the connector 103 is fixedly connected to the right side of the door lock 101.

[0020] Reference Figure 1-5 The mounting component 2 includes a mounting body 201, a first thread 202, a slot 203, and a retaining ring 204. The mounting body 201 is located inside the connecting body 103, and the first thread 202 is provided on the outer side of one side of the mounting body 201. The mounting body 201 is rotated and engaged inside the connecting body 103 through the first thread 202. The slot 203 is opened on the inner side of the mounting body 201, and the retaining ring 204 is movably engaged in the slot 203. This facilitates the quick disassembly of the lock body component 1 and the mounting component 2 after rotating the mounting body 201, making maintenance easier.

[0021] Reference Figure 1-5The main buffer assembly 3 includes a buffer cavity 301, a first compression column 302, a fixed side plate 303, a fixed hole 304, an adjusting column 305, an adjusting groove 306, a second thread 307, and a spring 308. The buffer cavity 301 is movably engaged inside the mounting body 201, and the mounting body 201 is located on one side of the retaining ring 204. One side of the first compression column 302 is movably sleeved inside the buffer cavity 301. The fixed side plate 303 is located on the right side of the first compression column 302, and symmetrical openings are provided on both sides of the fixed side plate 303. The adjusting column 305 is rotatably sleeved inside the first compression column 302, and an adjusting groove 306 is provided on the right side of the adjusting column 305. A second thread 307 is provided on the outer side of one side of the adjusting column 305. The spring 308 is located in the inner cavity of the buffer cavity 301, on the left side of the adjusting column 305. This allows the adjusting column 305 to move inside the buffer cavity 301 and the first compression column 302 by rotating the adjusting column 305, thereby changing the stroke of the spring 308 and adjusting the elastic force of the spring 308.

[0022] Reference Figure 1-3 and Figure 6 The secondary buffer assembly 4 includes a rubber pad 401, a cavity 402, an exhaust port 403, a second compression column 404, a sealing ring 405, and a fixing ring 406. The rubber pad 401 is fixedly sleeved on the right side of the mounting body 201. The cavity 402 is symmetrically installed on one side of the fixed side plate 303, and exhaust ports 403 are evenly distributed on one side surface of the cavity 402. The second compression column 404 is movably sleeved inside the cavity 402, and a sealing ring 405 is fixedly sleeved on one side of the second compression column 404. The ring 406 is fixedly connected to the left side of the second compression column 404. When the impact on the lock body assembly 1 and the mounting assembly 2 is small, the rubber pad 401 is pushed to the right. The rubber pad 401 contacts the fixing ring 406 and deforms to offset the impact force. When the impact force is large, the fixing ring 406 pushes the second compression column 404 and the sealing ring 405 into the cavity 402 for compression. After moving to the right side of the exhaust hole 403, the air in the cavity 402 cannot be discharged, so the air is gradually squeezed until the impact force disappears.

[0023] The working principle of this utility model: First, the entire assembly is installed on the car door through the fixing hole 304. When the lock body assembly 1 and the mounting assembly 2 are subjected to a small impact, the rubber pad 401 is pushed to the right. The rubber pad 401 contacts the fixing ring 406 and deforms to offset the impact force. Secondly, when the impact force is large, the fixing ring 406 pushes the second compression column 404 and the sealing ring 405 into the cavity 402 to compress. After moving to the right side of the exhaust hole 403, the air in the cavity 402 cannot be discharged, so the air is gradually squeezed until the impact force disappears. At the same time, the buffer cavity 301 will also compress the spring 308 to offset the impact force. Finally, the adjusting column 305 can be rotated through the adjusting groove 306 to move inside the buffer cavity 301 and the first compression column 302, changing the stroke of the spring 308 and adjusting the elastic force of the spring 308. After the main buffer assembly 3 or the secondary buffer assembly 4 is damaged, the mounting body 201 can be rotated and twisted to separate the connecting body 103 from the first thread 202. Then, the retaining ring 204 can be removed with tweezers, and the main buffer assembly 3 and the secondary buffer assembly 4 can be taken out for repair or replacement.
