Description

Technical Field

[0001] This utility model relates to the field of buckle technology, specifically a limiting structure for automotive seat belt buckles. Background Technology

[0002] The limiting structure of the car seat belt buckle is a crucial safety component in the seat belt system. Its main function is to ensure that the buckle can be securely locked after being inserted into the latch receiver, and will not accidentally come off during normal use and dynamic changes in the vehicle (such as bumps, acceleration and deceleration), while being easily unlocked by pressing the release button when needed.

[0003] When in use, when the buckle is inserted into the latch receiver, the spring will push the latch into the hole in the buckle to complete the limit. At the same time, the spring will push the latch to prevent the latch from disengaging from the buckle when the vehicle moves. However, after a long period of use, the performance of the spring will deteriorate, resulting in a decrease in the spring force, which will increase the risk of the latch disengaging from the buckle. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model proposes a limiting structure for automotive seatbelt buckles.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a limiting structure for a car seat belt buckle, comprising a latch receiver body, a buckle, a latch and a spring, wherein a clearance groove is provided on the side wall of the latch receiver body, and a magnet is fixedly connected to the inner wall of the clearance groove, the side wall of the magnet is in contact with the latch, the latch is made of magnetic material, and a button is provided on the top of the latch, with one end of the button penetrating through the latch receiver body and extending to the outside of the latch receiver body.

[0006] Preferably, a limiting groove is formed on one side wall of the locking tongue, and a limiting post is slidably connected to the inner wall of the limiting groove. A spring is sleeved on the outer wall of the limiting post, and the limiting post is fixedly connected to the main body of the locking tongue receiver.

[0007] Preferably, the outer wall of the limiting post is fitted with an adjusting plate, and the side wall of the adjusting plate is fixedly connected to the spring. The outer wall of the locking tongue receiver body is rotatably connected with a bolt, and one end of the bolt passes through the locking tongue receiver body and extends into the interior of the locking tongue receiver body. One end of the bolt located inside the locking tongue receiver body is threadedly connected to the adjusting plate.

[0008] Preferably, the side wall of the latch is provided with a circular hole, and a limiting shaft is provided in the circular hole, with one end of the limiting shaft being fixedly connected to a bolt.

[0009] Preferably, the side wall of the button is provided with a strip groove, and a protrusion is provided in the strip groove, the protrusion being fixedly connected to the inner wall of the latch receiver body.

[0010] Preferably, the main body of the latch receiver includes a housing and a rear cover, the outer wall of the rear cover is provided with a screw, and one end of the screw passes through the rear cover and is threadedly connected to the housing.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. This utility model, by incorporating a magnet, allows the locking tongue to be disengaged from the hole in the buckle when the button is pressed during use. When the buckle is inserted, a spring pushes the locking tongue into the hole within the buckle, thus limiting its movement. Even if the spring's performance deteriorates over time, the magnet retains the buckle, making it difficult for the locking tongue to detach from the buckle due to vehicle dynamics. This reduces the risk of the locking tongue disengaging from the buckle and improves the device's safety. Furthermore, unlike the spring, the magnet's mechanical properties do not deteriorate with prolonged use, providing a longer safety guarantee period.

[0013] 2. This utility model, by setting an adjustment plate and a bolt for use together, can adjust the spring after its performance is reduced by rotating the bolt. Rotating the bolt causes the bolt to move the adjustment plate, which compresses one end of the spring, thereby adjusting the degree of spring compression and storing force for the spring. Moreover, the adjustment of this device is convenient and can be made without opening the main body of the latch receiver. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Please see Figures 1 to 5 A limiting structure for a car seat belt buckle includes a latch receiver body 1, a buckle 2, a latch 3, and a spring 4. The side wall of the latch receiver body 1 is provided with a clearance groove, and a magnet 5 is fixedly connected to the inner wall of the clearance groove. The side wall of the magnet 5 contacts the latch 3. The latch 3 is made of magnetic material. A button 6 is provided on the top of the latch 3, and one end of the button 6 passes through the latch receiver body 1 and extends to the outside of the latch receiver body 1.

[0022] As can be seen from the above structure: by setting magnet 5, when using button 6, button 6 can press the locking tongue 3, causing the locking tongue 3 to disengage from the hole on the buckle 2. At this time, the buckle 2 can be pulled out. When the buckle 2 is inserted, after the buckle 2 is inserted to a certain position, the spring 4 can push the locking tongue 3 so that the locking tongue 3 enters the hole in the buckle 2, completing the limit. In this way, even if the performance of the spring 4 deteriorates due to long-term use, the magnet 5 can hold the buckle 2, making it difficult for the locking tongue 3 to disengage from the buckle 2 due to the dynamic changes of the vehicle. This reduces the risk of the locking tongue 3 disengaging from the buckle 2 and improves the safety of this device. Moreover, the performance of magnet 5 is different from that of spring 4. Its mechanical performance will not deteriorate due to long-term use, thus giving this device a longer safety guarantee time.

The bolt 9 located inside the latch receiver body 1 is threadedly connected to the adjusting plate 8. By setting the adjusting plate 8 and the bolt 9 to work together, the performance of the spring 4 can be adjusted by rotating the bolt 9. Rotating the bolt 9 causes the adjusting plate 8 to move, and the adjusting plate 8 compresses one end of the spring 4, thereby adjusting the degree of compression of the spring 4 and storing force for the spring 4. Moreover, the adjustment of this device is convenient and does not require opening the latch receiver body 1.

[0025] Furthermore, a circular hole is provided on the side wall of the locking tongue 3, and a limiting shaft 10 is provided in the circular hole. One end of the limiting shaft 10 is fixedly connected to the bolt 9. By providing the limiting shaft 10, one end of the bolt 9 can be limited to ensure the stability of the bolt 9 when it rotates.

[0026] Furthermore, a strip groove 11 is provided on the side wall of button 6, and a protrusion 12 is provided in the strip groove 11. The protrusion 12 is fixedly connected to the inner wall of the latch receiver body 1.
