Background technology

The invention of automobile, the trip for giving people bring great convenience；With the continuous development of auto industry, people are not only Safety and the comfortableness of driving are required, while also requiring that the multifunctionality of automobile；But when running car is in desert Or when on the dirt road of miriness, due to the impact of the factors such as weather condition or geographical environment, the tire of automobile is often absorbed in In sand pit or heatable adobe sleeping platform, at this moment cannot just sail out of and stranded；Especially northern ice climate in the winter time, accumulated snow on road, ground Wet and slippery, many automobiles can all run into the wet and slippery problem of road, and accident often occurs.

There is the device that many automobile pits are saved oneself in prior art, its principle is also different.Wheel side is raised mainly Method, stranded cable method, increase tire method of soil fertility etc..

The patent of applying date 2011.03.16, application number 201110062891.X discloses a kind of single-degree-of-freedom vehicle and falls into car Self-help apparatus, belong to auto parts Design and machining of products technical field.It is by supporting mechanism, hydraulic jack and base plate group Into；On both sides vehicle body of the device between tire before and after automobile, which by vehicle along perpendicular to ground direction jack-up can be Hard thing is encased inside under the tire for falling into mud or rescuing plate provides sufficient space, so as to realize the Pitted-vehicle self-help function of vehicle, the device Using raise method for vehicles.

Applying date 2011.06.11, the patent stranded cable-type self-rescue device for bogged automobile of application number 201120195130.7, bag Include wheel, it is characterised in that：One group of stranded cable rope part is provided with wheel, each stranded cable rope part is by becket bridle, ran, rope hook connection structure Into each stranded cable rope part passes through rope by rope hook from the gap location of a corresponding hub for vehicle wheel after one circle of wheel rubber tyre winding Ring, a drawing hawser are hung on the rope hook of each stranded cable rope part, pull the rope that one of stranded cable rope part is fixed in hawser one end On hook, the other end is relatively fixed with fixture.The simple structure of the present invention, makings, carry and using all easily, it is sunken in automobile When entering miriness or desert vehicle wheel skidding, this device is installed in the driving moment of the one or both sides of automobile, automobile is advanced slowly Or fall back, indirect labor ensures that drawing hawser is fallen in the rope hook of stranded cable rope part, and the device is fixed on fixture using stranded cable Method.

Applying date 2015.05.25, the patent of application number 201520343081.5 disclose a kind of automobile escape machine tire Pawl, including interior pawl, outer pawl, skid resistant course, connecting plate；The interior pawl and outer pawl are vertical circular arc angular structure, the interior pawl with it is outer Pawl by the interlaced chute being plugged on below skid resistant course of card article, be provided with above the skid resistant course be horizontally arranged with it is a plurality of Triangle tread plate, the pawl end of the interior pawl are provided with two sections, and by chute and the mobile adjustment length of slide plate；It is described outer Be provided with draw-in groove on the outside of pawl pawl end, the interior pawl pawl end and outer pawl pawl end are provided with multiple connecting holes, the connecting hole with Connecting plate connects；Two end of the connecting plate is provided with hook；The device is fixed on pitfall tire, increases the solid soil fertility of tire, from And increase its nonslip properties.

But said structure also be present：First, single function, can only adapt to single pitfall operating mode, with office It is sex-limited, it is impossible to select method of suitably getting rid of poverty as the case may be；2nd, and prior art is grasped only for pitfall wheel Make, the method for also not having to realize homonymy front and back wheel Synchronous Transmission.

For non-four-wheel drive cars, if it is possible to make its drivewheel, driven pulley Synchronous Transmission, its ability of getting rid of poverty will significantly Increase.

6. automobile tire pitfall self-help apparatus using method according to claim 3, it is characterised in that：In accordance with the following steps Carry out：

Step 1, the method that device is fixed：

Step 1.1：Screw rod (15) is screwed out from sliding nut (14), " U " the type fixation clamp (1) is enclosed within tire outer Side is rearward at position, is revolved behind the space for then sequentially passing through on the second waist-shaped hole (13b), wheel hub between spoke by screw rod (15) again Enter and temporarily fix in the sliding nut (14), adjust position of the inserted link (12c) in blind hole (11c) and then adjust the first vertical pole (11b) the distance between with the second vertical pole (12b), to adapt to the tire of different in width, adjusting screw rod (15) and sliding nut (14) position, so as to adapt to the wheel hub of different shaping；

Step 1.2：Adjusting rod (2) described in " U " the type fixation clamp (1) as fulcrum, makes the adjusting rod (2) lower end position In tire anterior position, while along the slide bar (21) the slip concentric fixed disk (3) so that disc body (31) circle The heart is alignd with hub centre, finely tunes the angle of the disc body (31), and selection is alignd with the jack (33) axle center or substantially The wheel hub fixing threaded hole of alignment, original fixing bolt on wheel hub fixing threaded hole is pulled down, and by the threaded shank of the fixing bolt It is once again screwed into after corresponding jack (33) in the wheel hub fixing threaded hole, the screw head portion of the fixing bolt is stuck in the gross porosity (33b) bottom, completes to fix, when the spiro rod length of the fixing bolt is inadequate, using after lengthening corresponding with the bolt Bolt replaces；

Step 1.3：Screwing screw rod (15) makes the first jig arm (11) be tightly secured on tire outer with the second jig arm (12)；

Step 2, the method that driving moment is got rid of poverty:

Step 2.1, the method got rid of poverty using fixed plate：When automobile drivewheel is absorbed in hole, according to the side described in step one Method is fixed on the present invention on drivewheel, needs to be connected fixed plate (4) with expansion link (23), by the through hole (23d) interpolation Enter elongated rod body, its rotation is limited with hand steered firmly fixed plate (4), rotate the circular screwed pipe (23a) by leverage, it is described Screw mandrel (23c) is screwed out from screw (23b) two ends, increases expansion link (23) length until the fixed plate (4) is connected to ground On face, start up the car, driving moment is rotated, vehicle wheel rotation drives the adjusting rod (2) to rotate, and the adjusting rod (2) will be described Automotive wheel is lifted so that automobile is got rid of poverty；

Step 2.2, the method got rid of poverty using rope：The present invention is fixed on drivewheel according to the method described in step 1, by institute State fixed plate (4) to remove from the expansion link (23), pass through string holes (34b) and then knot using the near-end of steel wire rope and fix, Steel wire rope is wound into some circles on the wire casing (34), the distal end of steel wire rope is fixed on into ground or other vehicles then On, starting up the car rotates drivewheel, drives concentric fixed disk (3) to rotate, is got rid of poverty by the pull strap electrical automobile of steel wire rope；

Step 2.3, homonymy front and back wheel synchronously drive the method got rid of poverty：Will be the front and back wheel of homonymy equal according to the method described in step 1 The fixed present invention, is rotated so as to realize homonymy front and back wheel together by the synchronous belt pulley transmission between concentric fixed disk (3), this kind of In the case of optionally install or remove on two-wheeled the fixed plate (4) of the present invention by the fixed plate (4) of the present invention on two wheels all Pull down, reservation is absorbed in hole the fixed plate (4) of the present invention or whole fixed plates (4) for retaining the present invention on two-wheeled on wheel, sends out Electrical automobile makes homonymy front and back wheel synchronous axial system, so as to band electrical automobile is got rid of poverty；Above step 2.1, step 2.2, step 2.3 are regardless of elder generation Afterwards, it is applied in combination or a damp use.
