Description

Technical Field

[0001] The utility model belongs to the technical field of automobile safety belts, in particular to an anti-collision safety belt assembly. Background Art

[0002] Car seat belts are safety devices designed to restrain occupants in a collision and to prevent them from colliding with the steering wheel, dashboard, or other components, or from being thrown out of the car and causing death or injury. The woven belt is connected to the lock seat through a lock to secure the driver to the seat. Due to the tension of the seat belt retractor, the lock will be quickly reset to one side of the seat when it separates from the lock seat. Since the lock shell is made of hard plastic, the process of resetting it to the side of the seat will impact the B-pillar trim on the inside of the cab, which will cause many scratches on the B-pillar trim over time. Utility Model Content

[0003] The technical problem to be solved by the present invention is to provide an anti-collision safety belt assembly in response to the above-mentioned defects, which protects the lock housing and the B-pillar trim during the lock resetting process and prevents the B-pillar trim from being scratched due to impact.

[0004] The technical solution adopted by the utility model to solve its technical problems is as follows: an anti-collision safety belt assembly includes a lock seat, a lock shell arranged above the lock seat, a lock tongue arranged on the lock shell and connected to the lock seat, and a safety belt arranged on the lock shell, the front end surface of the lock shell is provided with a front anti-collision surface, the front anti-collision surface is folded backward to form an anti-collision edge surrounding the lock shell, the rear end surface of the anti-collision edge is provided with an inlet for the lock shell to enter the interior of the anti-collision edge, and the anti-collision edges on both sides of the inlet are symmetrically provided with abutments against the rear end surface of the lock shell. The first rear anti-collision surface and the second rear anti-collision surface are touched, and the top and bottom ends of the first rear anti-collision surface and the second rear anti-collision surface are spaced from the inner walls of the two ends of the anti-collision edge. The rear end face of the first rear anti-collision surface is provided with a locking block, and the outer surface of the locking block is provided with a connecting groove. The rear end face of the second anti-collision surface is provided with a fixing block, and the fixing block is provided with a connecting piece with a U-shaped structure that matches the connecting groove. The opening of the connecting piece is connected to the top and bottom end of the fixing block respectively, and the bottom end of the anti-collision edge is provided with a lock tongue avoidance hole that matches the lock tongue.

[0005] Furthermore, the front anti-collision surface, the anti-collision edging, the first rear anti-collision surface, the second rear anti-collision surface, the locking block, the fixing block, and the connecting piece are all made of rubber.

[0006] Furthermore, after the outer surface of the lock shell collides with the front anti-collision surface, the anti-collision edge, the first rear anti-collision surface, and the second rear anti-collision surface, the inner wall of the connecting member collides with the connecting groove, driving the first rear anti-collision surface and the second rear anti-collision surface to form a lock.

[0007] Furthermore, the front end surface of the lock housing is symmetrically provided with a first limiting groove, a positioning groove is provided between the two first limiting grooves, and the front anti-collision surface is provided with a first limiting block matching the first limiting groove and a positioning block matching the positioning groove.

[0008] Furthermore, second limiting grooves are provided on both sides of the lock housing, and second limiting blocks matching the second limiting grooves are provided on the inner side wall of the anti-collision edging.

[0009] Furthermore, third limiting grooves are provided on both sides of the rear end surface of the lock housing, and third limiting blocks matching the third limiting grooves are provided on the front end surfaces of the first rear anti-collision surface and the second rear anti-collision surface.

[0010] The beneficial effects of the utility model are:

[0011] The utility model forms a covering on the outer surface of the lock shell by coordinating the front anti-collision surface, the anti-collision edging, the first rear anti-collision surface, the second rear anti-collision surface, the locking block, the connecting groove, the fixing block, the connecting piece, and the lock tongue avoidance hole. The cooperation of the connecting piece and the connecting groove prevents the lock shell from being separated from the front anti-collision surface, the anti-collision edging, the first rear anti-collision surface, and the second rear anti-collision surface. When the lock shell is reset, the original hard impact contact between the lock shell and the B-pillar trim is changed to flexible contact, thereby preventing the B-pillar trim from being scratched due to the lock shell hitting the B-pillar trim.

[0019] The present invention will be further described below with reference to the accompanying drawings.

[0020] Reference Figure 1-5 As shown, the anti-collision seat belt assembly includes a lock seat 1, a lock shell 2 arranged above the lock seat 1, a lock tongue 3 arranged on the lock shell 2 and connected to the lock seat 1, and a seat belt 4 arranged on the lock shell 2. The top of the rear end surface of the lock shell 2 is provided with a through-type belt hole 13 for the seat belt 4 to cooperate with the lock shell 2. The front end surface of the lock shell 2 is provided with a front anti-collision surface 501, which is folded backward to form an anti-collision edge 502 that surrounds the lock shell 2. The front anti-collision surface 501 and the anti-collision edge 502 are integrally formed to form an accommodating space that matches the lock shell 2 and covers the lock shell 2. The material of the rubber material changes the original hard impact contact between the lock shell 2 and the B-pillar trim into flexible contact, thereby preventing the B-pillar trim from being scratched due to the lock shell 2 hitting the B-pillar trim.

[0021] The rear end surface of the anti-collision edging 502 is provided with an inlet 6 for the lock shell 2 to enter the interior of the anti-collision edging 502. The size of the inlet 6 is smaller than the lock shell 2, and its rubber material causes the anti-collision edging 502 and the front anti-collision surface 501 to produce elastic deformation, which is convenient for the lock shell 2 to enter the interior from the inlet 6, and the lock shell 2 is not easily separated from the anti-collision edging 502 from the inlet 6, making its retaliation more firm and stable. The anti-collision edging 502 on both sides of the inlet 6 is symmetrically provided with a first rear anti-collision surface 503 and a second rear anti-collision surface 504 that conflict with the rear end surface of the lock shell 2. The first anti-collision surface 503 and the second anti-collision surface 504 are also made of rubber material and are integrally formed with the anti-collision edging 502. They cover the rear end surface of the lock shell 2 and the inlet 6, and the first anti-collision surface 503 and the second anti-collision surface 504 can be opened to both sides, which is convenient for the lock shell 2 to enter the anti-collision edging 502 from the inlet 6.

[0022] The top and bottom ends of the first rear anti-collision surface 503 and the second rear anti-collision surface 504 leave a gap with the inner walls of the two ends of the anti-collision edge 502. The upper and lower gaps can avoid the position where the safety belt 4 passes through the lock shell 2. The rear end face of the first rear anti-collision surface 503 is provided with a locking block 7, and the outer surface of the locking block 7 is provided with a connecting groove 701. The rear end face of the second anti-collision surface 504 is provided with a fixing block 8. The fixing block 8 is provided with a U-shaped connecting piece 801 that matches the connecting groove 701. The opening of the connecting piece 801 is connected to the top and bottom ends of the fixing block 8 respectively. The connecting piece 801, the fixing block 8 and the locking block 7 are all made of rubber. After the first rear anti-collision surface 503 and the second rear anti-collision surface 504 form a covering on the lock housing 2, the connecting piece 801 is pulled to cause it to undergo elastic deformation and be sleeved on the outer surface of the fixing block 8. As the directional force of the connecting piece 8 is restored, the connecting piece 8 is firmly in contact with the connecting groove 701 of the locking block 7, and then the lock housing 2 is fixed to the front anti-collision surface 501, the anti-collision edge 502, the first rear anti-collision surface 503 and the second rear anti-collision surface 504, making the covering more firm and stable, and not easy to be offset and fall off due to external force.

[0023] A lock tongue avoidance hole 301 matching the lock tongue 3 is provided at the bottom end of the anti-collision edging 502. After the lock head housing 2 enters from the entrance 6, the lock tongue 3 passes through the lock tongue avoidance hole 301 and extends to the outside of the anti-collision edging 2, so as to facilitate the connection between the lock tongue 2 and the lock seat 1.

[0024] The front anti-collision surface 501, the anti-collision edging 502, the first rear anti-collision surface 503, the second rear anti-collision surface 504, the locking block 7, the fixing block 8, and the connecting piece 801 are all made of rubber material with flexible contact. When the lock tongue 3 is separated from the lock seat 1, the lock housing 2 is not easily scratched by impact on the B-pillar trim.

[0025] After the outer surface of the lock shell 2 collides with the front anti-collision surface 501, the anti-collision edge 502, the first rear anti-collision surface 503, and the second rear anti-collision surface 504, the inner wall of the connecting member 801 collides with the connecting groove 701, driving the first rear anti-collision surface 503 and the second rear anti-collision surface 504 to form a lock.

[0026] The front end surface of the lock shell 2 is symmetrically provided with a first limiting groove 201, and a positioning groove 202 is provided between the two first limiting grooves 201. The front anti-collision surface 501 is provided with a first limiting block 9 matching the first limiting groove 201 and a positioning block 10 matching the positioning groove 202. Second limiting grooves 203 are provided on both sides of the lock shell 2, and second limiting blocks 11 matching the second limiting groove 203 are provided on the inner side wall of the anti-collision edge 502. Third limiting grooves 204 are provided on both sides of the rear end surface of the lock shell 2, and third limiting grooves 204 are provided on the front end surface of the first rear anti-collision surface 503 and the second rear anti-collision surface 504 to match the third limiting groove 204. Multiple limiting blocks, limiting grooves, and positioning blocks and positioning grooves cooperate with each other to make the cooperation between the front anti-collision surface 501, the anti-collision edge 502, the first rear anti-collision surface 503, the second rear anti-collision surface 504 and the lock shell 2 more stable, not easy to be offset due to external force, and make its fixation more firm and stable.

[0027] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Any simple modification or equivalent change made to the above embodiment based on the technical essence of the present invention shall fall within the scope of protection of the present invention.
