Description
Technical field
The utility model relates to a kind of parts for vehicle safety belt system, particularly a kind of safety strap connecting device.
Background technology
All the time, the safety strap that possesses limit for tonnage restriction of called optical imaging, its object is, allows passenger load restriction ground displacement forward under unforeseen circumstances.Therefore, this Webbing retractor comprise the mandrel of separating and be arranged on mandrel and locking module between force-limit rod.So, constraint passenger's safety strap is fixed on mandrel, and the locking module being connected with mandrel can lock with the shell of self-propelled vehicle with respect to the fixing of Webbing retractor.At seatbelt lock and in the application force situation being limited by force-limit rod, the side that the fixing part of mandrel and safety strap can be extracted out at safety strap when triggering load limiting device rotate up.Thus, act on the level that the load on passenger is limited in being limited by load limiting device.
In addition, in nearest seat belt apparatus, possess pre-tightening device, its object is, in the situation that collide, waits the vehicle emergency causing, by eliminating the lax of ribbon, before passenger is forwards mobile, definite fixing, improves the protective value to driver and crew.Gunpowder is used in the action of pre-tightening device conventionally, and the application force of the gas producing during by gunpowder explosion is regained ribbon fast speed.
In addition, this Webbing retractor is also provided with ability absorption plant, when vehicle collision causes larger impulsive force, the inertia of following driver and crew moves and when acting on load on ribbon and surpassing predefined value, allow to discharge the ribbon of specified amount, the absorption of the ability of carrying out, alleviates the pressure that is applied to driver and crew's chest.
Yet, the lockable mechanism of mandrel and locking module, need to couple together under normal circumstances can synchronous rotary, this be because, both are not coupled together and make its synchronous rotary, the difficulty that can become while usually carrying out the batching and discharge of ribbon, becomes the reason that produces strange sound and rock.In this case, generally use expansion pin.
In addition, while using expansion pin connecting mandrel and locking module, once the accident of meeting accident, can there is fracture displacement with mandrel connecting portion in locking module, expansion pin form is in the past that upper and lower diameter is the same mostly, when there is fracture displacement, will make rupture cross section irregular like this, even can have influence on the energy absorbing of force-limit rod.
Utility model content
The purpose of this utility model is to provide a kind of safety strap connecting device that can avoid affecting because expansion pin rupture cross section is irregular force-limit rod energy absorbing.
The technical scheme that realizes the utility model object is: the utility model comprises framework, mandrel, force-limit rod and lock in emergency device; Described framework has the first parallel plate, the second parallel plate and is connected to the diaphragm plate between described the first parallel plate and the second parallel plate; Described the first parallel plate is provided with gear hole, and the second parallel plate is provided with circular hole; Described lock in emergency device comprises locking seat and being installed on it for detection of the sensor of vehicle emergency situation, and locking seat is provided with for engage the ratchet with lock in emergency safety strap with gear hole; Described mandrel has hollow bulb, and force-limit rod is arranged in hollow bulb; One end of described force-limit rod and mandrel are circumferentially fixing, and the locking seat in the other end and lock in emergency device is circumferentially fixing; The end face that described mandrel is relative with locking seat is provided with an above expansion pin, and on locking seat, correspondence position is also provided with a counter sink above and expansion pin is connected; Expansion pin on described mandrel is through the counter sink of correspondence position on locking seat and by the blunt office, expansion section of putting down at counter sink of compression machine.
Above-mentioned mandrel and the expansion pin arranging on it are integrated diecasting.
Above-mentioned mandrel and the expansion pin arranging on it are aluminium matter.
The end face that above-mentioned mandrel is relative with locking seat is provided with two expansion pins, and on locking seat, correspondence position is also provided with two counter sinks that are connected with expansion pin.
The utlity model has positive effect: (1) the utility model has been avoided because of the irregular problem that affects force-limit rod energy absorbing effect of expansion pin rupture cross section; (2) the utility model design is ingenious, simple in structure, manufactures simple and fast, and result of use is good.
