In the following description, when referring to the figures, the same reference numbers in different figures denote the same or similar elements, unless otherwise explained.

As shown in fig. 1 to 8, the present disclosure provides a spare tire installation aid including: the auxiliary tire wheel comprises an auxiliary sleeve 1, a plurality of hooks 2 and a driving assembly 3, wherein the hooks 2 are used for being clamped with a wheel rim of a spare tire wheel hub, and the hooks 2 are rotatably connected in a mounting groove 11 of the auxiliary sleeve 1; the driving assembly 3 is fixedly connected with the auxiliary sleeve 1, the driving assembly 3 comprises a movable joint 31 which can move up and down in the sliding groove 12 of the auxiliary sleeve 1, and a power part 32 connected with the movable joint 31, the plurality of hooks 2 respectively have a convex edge position 21 and a concave groove position 22, and the power part 32 drives the movable joint 31 to move between the convex edge position 21 and the concave groove position 22, so that the plurality of hooks 2 can be opened or retracted simultaneously.

Here, it should be noted that the spare tire installation auxiliary tool provided by the present disclosure needs to be used in cooperation with a vehicle assembling mechanical arm, and the mechanical arm drives the installation auxiliary tool to move so as to clamp and transport the spare tire. The power member 32 may be of any suitable construction, such as an air cylinder, hydraulic cylinder, linear motor, etc., as will be described in greater detail below, with reference to the air cylinder. In the initial state, the movable joint 31 is located at the groove position 22 and is retracted in the auxiliary sleeve 1, so that excessive space is not occupied; when the spare tire needs to be clamped, the power part 32 drives the movable joint 31 to move from the groove position 22 to the convex edge position 21, and the plurality of claws 2 are simultaneously opened to be clamped and transferred to a proper installation position; finally, the plurality of hooks 2 can be restored to the initial condition by gravity or by the power member 32 to disengage from the spare tire.

According to the technical scheme, firstly, the spare tire mounting auxiliary tool provided by the disclosure is adopted to clamp and place the spare tire at the mounting position in the trunk from the goods shelf, so that the labor is saved, the working efficiency is improved, and the labor intensity of workers is reduced; secondly, regarding the fixed positions of the hook claw 2 and the spare tire, the hook claw 2 is clamped in the rim, and the wheel rim is particularly suitable for an arrangement mode with hidden installation positions and small installation gaps, so that interference and friction with parts around a trunk in the installation process can be avoided, and the assembly quality of the whole vehicle is ensured; finally, from the joint power, the knuckle 2 and the spare tire do not lean on the frictional force to prevent the spare tire from dropping, but adopt the mode of joint to connect, and is firm reliable, solves the problem that the spare tire dropped in the transportation.

In an exemplary embodiment of the present disclosure, the power member 32 is a cylinder, and the movable joint 31 is fixed to an end of a piston rod of the cylinder by a connecting block 33. Specifically when the assembly, utilize the current high pressurized air source in assembly workshop, pass through the trachea with high pressurized air source and be connected with the gas pocket 322 on the pedestal 320, the operator is through controlling the arm, assist the utensil with this installation and remove to spare tyre position department, through controlling gas switch, it is gaseous in the cylinder body that gets into the cylinder through gas pocket 322, under the gas pressure effect, piston 321 downstream, and drive the downstream of movable joint 31 through connecting block 33, a plurality of hook 2 open the inside that stretches into the wheel rim and block. At this moment, the spare tire can be transferred to the mounting position of the trunk, and in the transfer process, the clamping state can be kept all the time as long as the cylinder does not actively exhaust. After transporting to mounted position department, the steerable gas switch of operator this moment exhausts, and the pressure above piston 321 disappears, and piston 321 drives movable joint 31 upward movement, and the knuckle 2 loses movable joint 31's supporting role this moment, packs up under the action of gravity to withdraw from in the wheel rim of spare tyre wheel hub, later carry out the bolt by operating personnel and tighten the spare tyre, accomplish the assembly process of whole spare tyre.

Specifically, as shown in fig. 3, a recess opening toward the movable joint 31 is formed on a side wall of the finger 2 facing away from the click surface, wherein the movable joint 31 is located in a groove of the recess when the plurality of fingers 2 are retracted; when the plurality of fingers 2 are opened, the movable joint 31 abuts against the lower flange position of the notch, and the movable joint 31 moves downward to the extreme position. Before the spare tire is grabbed, no gas is introduced into the seat body 320 of the power part 32, the movable joint 31 is positioned at the groove position 22, and the plurality of hooks 2 can be contracted together under the action of gravity; when the power member 32 drives the movable joint 31 to move downwards, the movable joint 31 will move from the groove position 22 of the hook 2 to the lower convex position, and in this process, under the thrust action of the movable joint 31, the plurality of hooks 2 simultaneously rotate outwards to be clamped. In addition, through setting for the connected position, the size etc. of piston 321, piston rod and movable joint 31 to the cylinder, can guarantee when movable joint 31 moves to protruding edge position 21, piston 321 can just in time move to the diapire of pedestal 320, promptly, piston 321 is in the extreme position of motion in-process, can make a plurality of claws 2 keep opening the state, the joint of being convenient for, simultaneously at the joint in-process, can not rock the risk that produces and drop because of the spare tyre.

As shown in fig. 3 and 5, the joint end of the hook 2 can be configured to be an L-shaped structure, so that the rim of the spare tire can be just jointed to the flange structure of the hook 2, the outer diameter (the diameter of the circumference where the outermost edge of the horizontal section of the L-shaped structure is located) of the plurality of hooks 2 in the open state is larger than the diameter of the rim of the spare tire, and under the condition that the power part 32 is not actively unlocked, the hook 2 cannot be separated from the rim, so that the spare tire cannot fall off in the transportation process, and the production safety is improved.

In addition, in order to ensure that the surface of the rim is worn during the clamping process, in the present disclosure, a sheath 23 is fixed at least on the clamping surface of the finger 2, and the sheath 23 is fixed on the outer wall of the finger 2 by a plurality of first fastening members 24. The sheath 23 can be made of rubber, and the contact between the claw 2 and the spare tire is designed to be soft contact, so that the claw 2 can be prevented from wearing the paint surface of the rim.
