Problems solved by technology
[0004] The technical problem to be solved by the present invention is: in view of the prior art, only one head of the retractor can limit the force of the occupant's upper shoulder strap, resulting in different tensions between the upper shoulder strap of the seat belt and the lower shoulder strap of the seat belt. Then lead to the problem that the occupant's chest compression is too large, and a safety belt buckle structure and an automobile

Embodiment Construction
[0022] In order to make the technical problems, technical solutions and beneficial effects solved by the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0023] Such as figure 1 and figure 2 As shown, an embodiment of the present invention provides a safety belt buckle structure, including a breakable component 3, a lap belt locking component 2 connected to the safety belt waist belt 9, and a shoulder belt locking component 2 connected to the lower shoulder belt 7 of the safety belt , the waist belt locking component 1 and the shoulder belt locking component 2 are connected through the breakable component 3; when the force of the shoulder belt 7 under the safety belt reaches a preset threshold, the breakable component 3...

The invention belongs to the technical field of auto parts, in particular to a safety belt buckle structure and an automobile. The safety belt buckle structure includes a breakable component, a lap belt locking component connected to the lap belt of the safety belt, and a shoulder belt locking component connected to the lower shoulder belt of the safety belt, the waist belt locking component and the shoulder belt locking component pass through the The breaking component is connected; when the force of the under-seat belt shoulder strap reaches a preset threshold, the breakable component breaks, and the under-safety belt shoulder belt drives the shoulder belt locking component to separate from the lap belt locking component. The present invention effectively controls the force of the shoulder belt under the safety belt of the occupant in the vehicle, reduces the injury probability of the occupant, and simultaneously realizes the waist belt force received by the seat belt waist belt position and the shoulder belt force received by the seat belt lower shoulder belt position Blocking, so that the force of the occupants in the car does not interfere with each other at the above two positions.
Description
technical field [0001] The invention belongs to the technical field of auto parts, in particular to a safety belt buckle structure and an automobile. Background technique [0002] The seat belt is the most important safety component for the safety restraint of the occupants in the vehicle. [0003] When a car collides, usually through the torsional deformation of the built-in force limiting rod of the retractor, the seat belt in the retractor is moderately released at the position of the upper shoulder belt of the occupant, and the position of the upper shoulder belt of the occupant is adjusted by the released seat belt. Control the force on the occupant's chest, thereby controlling the compression amount of the occupant's chest. In the prior art, only one head of the retractor can limit the force of the upper shoulder belt of the occupant through the reel and the force limiting rod, which will cause the tension of the upper shoulder belt of the seat belt to be different fr...
