Embodiment 1
[0020] see figure 2 and image 3 , this example designs a noise-absorbing safety belt buckle, including a pin, a lock body, a latch, a spring, a top block, a cantilever and a housing. A buffer body 8 is wrapped around the outside of the latch 4 .
[0021] When the occupant wears the seat belt, that is, when the seat belt bolt is inserted into the seat belt buckle of this example, the whole mechanism follows the following motion: the dead bolt is inserted into the lock body 3 and contacts the top block 6, and the top block 6 moves along the middle of the lock body 3. The slot 9 of the corresponding position slides horizontally. At this time, the spring 5 arranged between the latch 4 and the cantilever 7 is in a compressed state, pushing the cantilever 7 to move downward and forward. Since the cantilever 7 and the jacking block 6 are connected to each other through the shaft on the jacking block 6, the cantilever 7 makes relative rotational movement around the shaft. Simult...

The invention relates to the technical field of automobile safety belts, in particular to a noise reducing safety belt buckle. The noise reducing safety belt buckle comprises a pin, a lock body, a lock latch, a spring, an ejector block, a cantilever and a shell, wherein the outer side of the lock latch is wrapped by a buffering body of a hollow structure, the pipe wall on one side of the buffering body is provided with two notches, the buffering body is divided into a left section, a middle section and a right section through the two notches, the left section and the right section of the buffering body are arranged at the two ends of the lock latch in a sleeved mode and located at the contact position of the tail end of the lock body and the lock latch, and the middle section of the buffering body is located on one side of the lock latch. Compared with the prior art, the buffering body is additionally arranged between the lock body and the lock latch and designed to be of a hollow three-section structure, so that vibration and collision of metal parts in the safety belt buckle are relieved; when a locking dog is inserted into the safety belt buckle, noise generated when the lock latch rapidly rotates to reach the ending position and collides with the lock body is lowered, and therefore the comfort degree of passengers is improved.
Description
technical field [0001] The invention relates to the technical field of automobile seat belts, in particular to a noise-reducing seat belt buckle. Background technique [0002] With the improvement of people's living standards, the requirements for vehicle performance are getting higher and higher not only in terms of power, economy, and safety, but also in terms of vehicle comfort, reliability, durability, and safety. . As an important evaluation index of car ride comfort, car noise will also reflect the design level and process level of the manufacturer to a large extent. [0003] Seat belt buckles, as part of automotive interior systems, also face the challenge of noise reduction. Because the distance between the seat belt buckle and the human ear is relatively close, passengers are more sensitive to the noise of the seat belt buckle, and OEMs also have high requirements for this part of the noise. [0004] figure 1 Shown is a conventional seat belt buckle structure, t...
