Abstract
The utility model relates to an automobile self-aid device. The automobile self-aid device is composed of an automobile battery, a motor, a pneumatic pump, a pneumatic reversing valve, pneumatic guide pipes, a cylinder and a cylinder clamp. The pneumatic pump is driven by the motor which is driven by the automobile battery. The pneumatic pump and the pneumatic reversing valve are connected by the pneumatic guide pipe. The pneumatic reversing valve is respectively connected with an air inlet and discharge opening and an air inlet and discharge opening on the front end and the rear end of the cylinder by the pneumatic guide pipes. The cylinder clamp is in the shape of a reverse omega, and the cylinder clamp and the lower surface of an automobile chassis are in thread connection. The front end of a cylinder body of the cylinder and the lower surface of the automobile chassis are in hinge-shaped connection, and the rear end of the cylinder body is connected to the lower surface of the automobile chassis by the cylinder clamp. When an automobile normally runs, the cylinder is arranged at the lower surface of the automobile chassis in parallel. When rear wheels for driving an automobile immerse a muddy pit ground, the rear end of the cylinder can be downwards moved, a piston rod acts on the ground to generate forward push force to the automobile and the automobile is forwards moved to run rattrap.
Description
Affiliated technical field
The utility model relates to a kind of self-auxiliary device of automobile, especially is in idle running and can't effectively work the time, automobile self can be implemented self-service a kind of device when the rear wheel that drives.
Background technology
As everyone knows, when the trailing wheel that drives automobile was absorbed in muddy ground, hole and occurs skidding, automobile usually was difficult to extricate oneself from a plight by the rotation of self wheel.In this case, people often take two kinds of measures: first, seek some hard things and pay for front at automobile back wheel first; Or to employ other vehicle that stranded automobile is pulled out.These methods are no doubt feasible, effective, but it usually is time-consuming, bothersome.In order to make automobile can have the function of oneself's rescue when taking turns thereafter, the present invention releases a kind of new automobile self-auxiliary device with being absorbed in muddy hole.Up to the present, also do not retrieved similar invention.
Summary of the invention
The objective of the invention is: set up a kind of self-auxiliary device for automobile, make the automobile that is absorbed in ground, muddy hole can be self-service.
A kind of automobile self-auxiliary device, it is made up of automobile storage battery, motor, air lift pump, gas pressure change valve, pressure catheter, cylinder, cylinder card; Air lift pump is by the motor-driven that drives with automobile storage battery; There is pressure catheter to be connected between air lift pump and the gas pressure change valve; Gas pressure change valve has pressure catheter to be connected respectively with porting A, the porting B of cylinder front and back end; The cylinder card is the shape of falling Ω, and the straight position at its two ends is drilled with through hole respectively, is provided with the bolt that connects with the lower surface of car chassis in the through hole; Its front end of the cylinder body of cylinder is hinge shape with the lower surface of car chassis and is connected, and the cylinder cutting ferrule is in the rear end of cylinder body, and is bound up on the lower surface of car chassis by the cylinder card.
Inventive principle: utilize the promotion repeatedly of car chassis lower cylinder piston rod, automobile is moved forward with another kind of power.
Effect of the present invention is: when back-wheel drive was invalid, automobile can rely on this self-auxiliary device to extricate oneself from a plight.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is that the piston rod of its cylinder of the utility model is in the scheme drawing when stretching out state.
Fig. 2 is that the piston rod of its cylinder of the utility model is in the scheme drawing when takeing in state.
Among each figure, 1, automobile storage battery, 2, motor, 3, air lift pump, 4, gas pressure change valve, 5, pressure catheter, 6, cylinder, 7, the cylinder card.
The specific embodiment
During cruising, cylinder (6) and the piston rod and the car chassis lower surface that are in the state of takeing in are parallel shape (as shown in Figure 2); When the driven vehicles trailing wheel was absorbed in muddy ground, hole, the driver is manual will to be screwed off by the cylinder card (7) that screw thread is fixed on the car chassis lower surface, makes cylinder (6) be in upper end tiltedly upright shape forward.Then, by automobile storage battery (1) drive motor (2), motor (2) makes air lift pump (3) work, and pressurized air enters the porting A of cylinder (6) front end by gas pressure change valve (4) and pressure catheter (5).Under compressed-air actuated effect, piston rod promptly stretches out (as shown in Figure 1) and acts on ground and make automobile reach.If the muddy highway section of automobile traveling is longer, the mode of staggered intake and exhaust that can be by porting A, the B automobile that moves forward.When after hours, pressurized air enters the porting B of cylinder (6) rear end by gas pressure change valve (4), makes piston rod be in the state of takeing in again.At last, the cylinder card (7) that will be placed in cylinder (6) rear end is coupled on the lower surface of car chassis by screw thread.
Claims (1)
1, a kind of automobile self-auxiliary device of being made up of automobile storage battery, motor, air lift pump, gas pressure change valve, pressure catheter, cylinder, cylinder card is characterized in that: this air lift pump is by the motor-driven that drives with automobile storage battery; There is pressure catheter to be connected between air lift pump and the gas pressure change valve; Gas pressure change valve has pressure catheter to be connected respectively with porting A, the porting B of cylinder front and back end; The cylinder card is the shape of falling Ω, and the straight position at its two ends is drilled with through hole respectively, is provided with the bolt that connects with the lower surface of car chassis in the through hole; Its front end of the cylinder body of cylinder is hinge shape with the lower surface of car chassis and is connected, and the cylinder cutting ferrule is in the rear end of cylinder body, and is bound up on the lower surface of car chassis by the cylinder card.
