Examples
A non-coaxial rotary spare tire device, as shown in fig. 1, comprising a rear compartment body 1, a rear compartment door 2 mounted on the rear compartment body 1, and a spare tire mounting assembly 3 mounted on the rear compartment body 1 and located at the side of the rear compartment door 2; the rear compartment door 2 is provided with a door handle 21, a combined connecting rod 22, a door lock 23, a spare tire lock 24, a spare tire carrier linkage rod 25 and a rear door hinge 26, and the combined connecting rod 22 is connected with the door handle 21 and the door lock 23. The spare tire installation assembly 3 comprises a pulley assembly 31 fixedly installed on the rear carriage body 1 through screws, a spare tire limiter 32 which is located below the pulley assembly 31 and close to the rear carriage door 2 and is fixed with the rear carriage body 1 through screws, a hand winch 33 which is located below the pulley assembly 31 and is fixed with the rear carriage body 1 through screws, a steel wire rope 34 which is led out by the hand winch 33 and penetrates through the pulley assembly 31, a spare tire frame 35 which is movably installed on the rear carriage body 1 and is connected with the steel wire rope 34 through screws, and a spare tire 36 installed on the spare tire frame 35. The spare tire carrier 35 includes a horizontal shaft 351, a vertical shaft 352 welded to the horizontal shaft 351 perpendicularly, and a mounting frame 353 having one end fitted to the vertical shaft 352 and rotatable about the vertical shaft 352. A hinge mount 3511 is mounted on the lateral shaft 351, and is hinged to the lateral shaft 351 and fixed to the rear vehicle body 1 by screws. Spare tire latch hole 3531 has been seted up to the one end of installation frame 353, the other end welded fastening of installation frame 353 has wire rope dead lever 3532, can nail wire rope 34 through wire rope dead lever 3532, conveniently withdraws or emits through hand winch 33 control spare tire rack 35.
In the present embodiment, the door lock 23 is an antiriot door lock with a model 1178.
In the present embodiment, the model of the spare tire lock 24 is OKL 6078.
The working principle is as follows:
as shown in fig. 1, the spare tire 36 is mounted on the mounting frame 353, specifically, the spare tire frame 35 can move in two directions, that is, the mounting frame 353 and the vertical shaft 352 rotate, and the horizontal shaft 351 and the hinge mounting seat 3511 cooperate to rotate in the rear compartment body 1, so that the spare tire frame 35 can move up and down, and the up and down movement is realized through the steel wire rope 34, the pulley combination 31 and the hand winch 33, and the spare tire 36 can move up and down through the gear reduction mechanism mounted in the hand winch 33, thereby achieving the purposes of time saving, labor saving and bidirectional safety locking; the spare tire 36 is rapidly rotated along the horizontal shaft 351 by the linkage relationship of the hand winch 33, the pulley combination 31 and the wire rope 34, the spare tire 36 is thereby raised, until the vertical shaft 352 abuts the spare tire stop 32, then, a safety pin is inserted to prevent the spare tire carrier 35 from rotating downwards along the horizontal shaft 351, at this time, the operation of the hand winch 33 is finished, the spare tire 36 is then manually pushed in the rearward door direction, causing the spare tire 36 to rotate along the vertical axis 352, then the spare tire rack linkage rod 25 is locked with the central hole of the spare tire 36 by a bolt, at the moment, the spare tire 36 is connected with the rear carriage door 2 into a whole, but the weight of the spare tire 36 is not on the door hinge 26, and non-coaxial rotation is achieved, when the door is closed, the door lock 23 locks the rear compartment door 2, meanwhile, the spare tire lock 24 is inserted into the spare tire latch hole 3531 to lock the spare tire carrier 35, so as to prevent vibration generated during the driving of the vehicle. When the door needs to be opened, the door handle 21 is pulled, the combined connecting rod 22 is driven to unlock the door lock 23 and the spare tire lock 24 simultaneously, the door can be normally opened, and then the spare tire can be easily disassembled according to the sequence of reversely assembling the spare tire.
The structure is characterized in that:
the design of coaxial rotation type spare tyre rack of back door non-, let vehicle back door hinge axle and spare tyre rotation axis independently bear, the while is again to the opening of back door, the switch is not influenced, it aggravates to have solved the back door that the spare tyre leads to because of the action of gravity on the back door, the switch, the dumb, the back door hangs down, the locking of back door and spare tyre is unstable, the opening of door, the synchronous scheduling problem of locking of switch and spare tyre, it only can open the spare tyre rack outside to have remedied, can open the tail door again after finishing, the defect that can not directly open simultaneously in the car, it is specific: compared with the existing spare tire mounting structure, the spare tire mounting structure for the heavy spare tire adopts the patent of the invention of the non-coaxial rotary spare tire frame of the rear door, and has the following innovation points: the winch type auxiliary lifting device has the advantages that the winch type auxiliary lifting device is adopted, labor can be greatly saved, labor intensity is reduced, working efficiency is improved, the winch has a bidirectional self-locking function, and the phenomenon that the spare tire is excessively heavy to cause reverse sliding down is effectively prevented. And the hidden trouble of installation is avoided. And secondly, a non-coaxial rotary design is adopted, so that the quality of the tire only acts on a spare tire rack when the requirement that the rear door is normally opened and closed is met, the rear door is flexibly opened and closed, the situations that the rear door is not flexibly opened and closed because the spare tire is directly installed on the rear door and the rear door is not flexible to open and close, the rear door is weighted, and the rear door falls down and the like are directly avoided. Thirdly, the function of one door and double locks is realized through the mechanism movement of the door handle and the combined connecting rod.
The utility model discloses technical effect mainly embodies in following aspect: after the heavy spare tire is installed, gravity does not directly act on the back door hinge, the internal and external opening and closing functions of the back door can not be influenced, the problems of falling prevention of the vehicle door and bearing of the back door hinge are greatly reduced, and the installation stability and flexibility of the back door and the spare tire are improved.
Of course, the above is only a typical example of the present invention, and besides, the present invention can also have other various specific embodiments, and all technical solutions adopting equivalent replacement or equivalent transformation are all within the scope of the present invention as claimed.
