Description

Technical Field

[0001] The utility model relates to the technical field of automobile safety belts, in particular to an intelligent active and passive pre-tightening automobile safety belt assembly. Background Art

[0002] At present, the most commonly used seat belts in automobiles are pre-tensioned seat belts. Under normal driving conditions, the pre-tensioned seat belts are the same as ordinary seat belts. The webbing can be freely contracted according to the needs of the occupants, so that the comfort of the occupants is guaranteed. When the acceleration of the car (or other factors) changes sharply, the mechanism in the seat belt can stop the webbing from contracting, thereby restraining the occupants in the seats and effectively protecting the lives of the occupants.

[0003] For example, a car safety belt with application number CN201410283113.7 that can prevent the upper body of a passenger from colliding forward comprises a left shoulder strap, a right shoulder strap, a left chest strap, a right chest strap, a left waist belt, a right waist belt, a left front waist belt and a right front waist belt, the upper ends of the left shoulder strap and the right shoulder strap are respectively fixed to the first fixing ring and the second fixing ring, the lower ends are respectively passed around the left positioning ring and the right positioning ring and are respectively buckled with the first length adjustment buckle and the second length adjustment buckle, one end of the left chest strap and the right chest strap are respectively fixed to the middle and upper parts of the left shoulder strap and the right shoulder strap, the other ends are respectively passed around the first lock buckle and the first locking tongue and are respectively buckled with the third length adjustment buckle and the fourth length adjustment buckle, one end of the left waist belt and the right waist belt are respectively fixed to the fifth fixing ring and the sixth fixing ring, the other ends are respectively passed around the left positioning ring and the right positioning ring and are respectively buckled with the fifth length adjustment buckle and the sixth length adjustment buckle, the left front waist belt is fixed to the second lock buckle after passing the left positioning ring, and the right front waist belt is fixed to the second locking tongue after passing the right positioning ring. However, when the car seat belt is used normally, the tightening mechanism automatically tightens the seat belt body, and the length cannot be adjusted for different groups of people. The seat belt may be too tight, resulting in low comfort for passengers. Therefore, in view of this, the existing structural deficiencies are studied and improved, and an intelligent active and passive pre-tensioning car seat belt assembly is proposed. Utility Model Content

[0004] The purpose of the utility model is to provide an intelligent active and passive pre-tensioning automobile safety belt assembly to solve the problems raised in the above-mentioned background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an intelligent active and passive pre-tensioning automobile seat belt assembly, comprising a seat belt body and a support frame, a support frame is arranged outside the seat belt body, and a connecting block is fixedly connected to one side of the support frame, the connecting blocks are symmetrically distributed with respect to the left and right sides of the support frame, and a tightening mechanism is fixedly connected inside the connecting block.

[0006] Preferably, the interior of the tightening mechanism includes a placement block fixedly connected to one side of the connection block, and a steel ball is movably connected inside the placement block, a baffle rod is provided on one side of the steel ball, and a gear is provided on one side of the baffle rod.

[0007] Preferably, a retractor is fixedly connected to one side of the gear, and a guide block is movably connected to the outside of the safety belt body.

[0008] Preferably, a storage mechanism is movably connected to the outside of the safety belt body, and a buckle is provided at the folding portion of the safety belt body.

[0009] Preferably, the storage mechanism includes a moving block movably connected to the outside of the safety belt body, and the outside of the moving block is rotatably connected to a rotating plate, the bottom of the rotating plate is fixedly connected to a clamping plate, and the top of the clamping plate is fixedly connected to a hook.

[0010] Preferably, the outside of the lock is movably connected to a card interface, and a magnetic block is arranged inside the card interface.

[0011] Preferably, a pressing block is fixedly connected to the outside of the card interface, and a fixing piece is fixedly connected to the bottom end of the safety belt body.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. The utility model provides a tightening mechanism and a storage mechanism, and different possible collision degrees cause different inertias. When the inertia reaches a critical point, when the vehicle brakes suddenly or is hit by an external impact, the steel ball hits the stop rod from the groove inside the placement block under the influence of inertia. The stop rod contacts the gear and plays a role of fixing the retractor. The stop rod blocks the gear, so that the retractor on one side of the gear is stuck. The passenger is tightly connected to the seat, and different protective forces are implemented to achieve the purpose of better protecting the occupant. The tightening mechanism can judge whether the safety belt body needs to be tightened according to the size of the inertia. In normal use, the comfort level of the passenger may be low due to the excessive tightening of the safety belt. First, take out a suitable length of the safety belt body, and fix the length of the safety belt body taken out by the moving block inside the storage mechanism. The passenger will not be strangled in the process of using the safety belt, which improves the comfort level of the passenger. A hook is added to the outside of the moving plate. When not in use, the lock buckle is placed above the hook to avoid the phenomenon of sitting on the lock buckle when getting on the vehicle, which is inconvenient and inconvenient to find the lock buckle quickly, thereby improving the convenience of using the safety belt body.

[0014] 2. The utility model increases magnetism and magnetic blocks inside the lock buckle. When fixing the seat belt body, the magnetic blocks inside the card interface can be adsorbed with the lock buckle to quickly connect the lock buckle and the card interface. When a passenger wants to fix the seat belt, he usually needs to measure the body to find the position of the card interface and then align it with the card interface to fix it. The operation is troublesome and inconvenient to use. With this new seat belt, when the lock buckle and the card interface are close, the magnetic block will quickly adsorb the lock buckle to fix the seat belt. BRIEF DESCRIPTION OF THE DRAWINGS
