Abstract
The utility model relates to a reaction motion type safety rod, belonging to the anti-collision device mounted on the automobiles. The utility model is to mount a buffer damper on the rear beam of the automobile frame; a force bearing rod is fixed to the rear end of the collision rod; one end of the force bearing rod is connected with the force bearing end of the buffer damper; a buffer spring is arranged between the front beam of the automobile frame and the collision rod. The safety rod has simple structure, low manufacturing cost and convenient installation and maintenance, and can greatly relieve the impulse force of the driver's seat position.
Description
Technical field
The utility model belongs to the collision prevention device of installing on the automobile, particularly a kind of improved safety lever.
Technical background
Traditional nerf bar be direct mount on the front cross rail of vehicle frame, this connection mode belongs to and is rigidly connected.When car during at low speed collision, normally collision bar is at first damaged, and relies on its intensity to protect operator's compartment; But during with speed of a motor vehicle collision faster, collision bar does not have any buffering, acts on operator's compartment with rigidity, directly with operator's compartment crimp, does not play a protective role substantially.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of recoil formula safety lever, and it is simple in structure, low cost of manufacture, and installation and easy to maintenance has buffer action preferably, can alleviate the impulsive force that the operator's saddle position is subjected to greatly.
Solving the scheme that technical matters of the present utility model adopts is: on the after cross member of vehicle frame isolation damper is housed, the collision bar rear portion is fixed with force rod, one end of force rod connects the force side of isolation damper, between the front cross rail of vehicle frame and collision bar recoil spring is housed.
This safety lever is because what adopt with vehicle frame is that isolation damper is connected; this is connected to non-rigid connection, and the great power after being clashed into is through after the buffering, remakes the after cross member that is used for vehicle frame; therefore can alleviate impact effectively, play protection preferably chaufeur to the operator's saddle position.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Each label is represented successively among the figure: collision bar 1, recoil spring 2, force rod 3, front cross rail 4, chute 5, longeron 6, operator's saddle 7, total stressed cross bar 8, chute 9, total stressed montant 10, fixed mount 11, piston 12, cylinder body 13, after cross member 14, outlet 15, locator card 16.
The specific embodiment
Safety lever referring to band cylinder formula damper shown in Figure 1.Isolation damper is contained on the after cross member 14 of vehicle frame, the main body of this damper is a fully enclosed cylinder body 13, resisting medium wherein is housed, the safety valve (not shown) is equipped with at outlet at bottom 15 places at cylinder body 13, when the pressure of resisting medium reaches predetermined value, safety valve can be opened, and allows resisting medium slowly gush; Be connected total stressed montant 10 with the piston 12 that cylinder body 13 matches, be connected with the firm of vehicle frame, also passing through longeron 6 weld togethers of fixed mount 11 and vehicle frame at its sidewall in order to guarantee cylinder body 13.The rear portion captive joint of collision bar 1 force rod 3, a pair of force rod 3 places the chute of being opened on the longeron 6 of vehicle frame both sides 5, the profile of chute 5 and size are consistent with force rod 3, and installing and locating card 16 on chute 5 again travels longitudinally thereby force rod 3 is limited in the chute 5.Force rod 3 symmetries are connected in the two ends of a total stressed cross bar 8, and the total stressed montant 10 of isolation damper is connected in the middle part of this total stressed cross bar 8.Between the front cross rail 4 of vehicle frame and collision bar 1, recoil spring 2 is housed also, thereby the strained condition of collision bar is balanced, can bear bigger impulsive force.Because the device that the vehicle frame front end is arranged is more, for the ease of this device being installed and in order to protect chaufeur better, total stressed cross bar 8 should be arranged in after the operator's saddle 7.The longeron 6 of vehicle frame both sides is provided with chute 9, and the two ends of total stressed cross bar 8 place chute 9, makes guiding longitudinally, and is more reliable when in a single day isolation damper is worked.The embodiment of this figure has only exemplified the specific embodiment of the safety lever of band cylinder formula damper, and equally also available spring-damper replaces cylinder formula damper and reaches identical purpose.
Claims (5)
1, a kind of recoil formula safety lever is characterized in that on the after cross member of vehicle frame isolation damper being housed, and the collision bar rear portion is fixed with force rod, and an end of force rod connects the force side of isolation damper, between the front cross rail of vehicle frame and collision bar recoil spring is housed.
2, by the described recoil formula of claim 1 safety lever, the longeron that it is characterized in that the vehicle frame both sides is provided with the size chute consistent with the force rod after the collision bar, locator card is housed on chute, force rod places chute, the force rod symmetry is connected in total stressed cross bar two ends, and the middle part of total stressed cross bar connects the total stressed montant of isolation damper.
3, by the described recoil formula of claim 2 safety lever, it is characterized in that total stressed cross bar is positioned at after the position of operator's saddle, the longeron of vehicle frame both sides is provided with the chute of total stressed cross bar.
