Background technology
At present, the structure of automobile driver seat mainly is made of cushion rack, seat cushion, back bracket, backrest, because being connected between seat cushion and the backrest is fixed type substantially, therefore also making the distance between chaufeur and the bearing circle is a fixed value.When taking place that automobile collides or during rear-end collision, the automobile head deforms because of collision, the space of operator's compartment also is extruded and dwindles, bearing circle in the operator's compartment directly pushes chaufeur especially and causes injures and deaths, its major cause is that the distance between the backrest of the bearing circle of operator's compartment and automobile driver seat fixes, when chaufeur is subjected to the bump of bearing circle, withstood by the backrest of the automobile driver seat of back, and chance of not escaping and the space that avoids pushing.China's utility model patent has provided a kind of " automobile driver safety seat backrest " for CN200420094337.5 number, this safety seat backrest comprises backrest and places its interior air bag, this air bag is provided with a valve and is connected with the impact switch of automobile head, and opened by its control; When automobile bumps or during rear-end collision, valve self-opening, air bag get final product exhaust, shrivelled, thus the space between augment direction dish and the back of seat.Though technique scheme can reduce the chaufeur injures and deaths to a certain extent, limited after all because of the backrest thickness of automobile driver seat, the space that is enlarged by air bags can be very not big, therefore, can't make chaufeur avoid the bump of bearing circle effectively.
The utility model content
The purpose of this utility model is to overcome the prior art above shortcomings; by improvement to the backrest structure of existing automobile driver seat; provide a kind of backrest automatic safe protective device of automobile driver seat; the backrest of this later-model automobile driver seat is not fixedly to be connected with seat cushion; thereby can take place that automobile collides or during rear-end collision; backrest is fallen down backward, guarantee that chaufeur has enough spaces to hide the bump of bearing circle.
The technical scheme that the utility model provides is: the backrest automatic safe protective device of this automobile driver seat includes cushion rack; seat cushion; back bracket; backrest; wherein seat cushion is arranged on the cushion rack; backrest is arranged on the back bracket; be characterized in also including the fixed sleeving and the latch of a cavity; have slotted eye on the sidewall of described fixed sleeving; have the through hole of Connection Block pad support on one end of described fixed sleeving; be inserted with the stock that can linear reciprocation moves in the other end of fixed sleeving; the part that this stock inserts in the fixed sleeving is provided with U-lag; this stock does not insert on the interior part of fixed sleeving and is with compression spring; the top that this stock does not insert the part in the fixed sleeving is provided with a spring storehouse; have the through hole that connects back bracket on the sidewall in this spring storehouse; the stay of described latch stretches in the slotted eye on the fixed sleeving sidewall and is stuck in the U-lag of stock; also be provided with arc sheetmetal on the part in stock inserts fixed sleeving, to guarantee the rotation of stock in fixed sleeving and flexible.
For better realizing the purpose of this utility model, also be provided with a centering device between the compression spring that is with on the described stock, this centering device is the sleeve pipe that is enclosed within on the stock, and its two ends contact with compression spring respectively, long and crooked to prevent single compression spring, thus elastic force influenced.
For better realizing the purpose of this utility model, the handle place of described latch also is provided with towing pad, be installed with hauling rope in this towing pad, the middle part of this hauling rope is in the rotating shaft of DC machine, its other end is connected with the shackle of electromagnetic switch front end, and DC machine, electromagnetic switch and the impact switch that is arranged on automobile head or top are connected and opened by its control.
Compared with prior art; the beneficial effects of the utility model are: have simple in structure, cost of manufacture is low, protection is effective and characteristics such as easy installation and removal; can take place that automobile collides or during rear-end collision; backrest is fallen down backward, guarantee that chaufeur has enough spaces to hide the bump of bearing circle.
