Description

Technical Field

[0001] The present invention relates to the technical field of vehicle emergency equipment, and more particularly to the field of auxiliary processing equipment for faulty wheels. Background Art

[0002] Vacuum tires have high elasticity and wear resistance, and have good adhesion and heat dissipation performance, and are widely used in various vehicles such as electric scooters, motorcycles, and automobiles. However, during the use of vacuum tires, it is inevitable that they will be punctured by sharp objects and leak air. If a vacuum tire leaks air, due to its own good elasticity and the pressure of the vehicle's own weight, the vacuum tire will be flattened and then close to the ground.

[0003] In real life, once a vehicle has a tire leak in a place far from a repair point, it will bring extremely inconvenient effects to the driver and passengers (even if a spare tire can be replaced, the operation is still difficult and cumbersome). At this time, if you insist on continuing to drive, not only will the tire and wheel hub be damaged, but it may also cause a traffic accident due to the difficulty of controlling the flat tire, resulting in personal injury. Summary of the Invention

[0004] In view of the above problems, the present invention provides a crawler-type tire self-rescuer with a simple structure, fast and convenient operation, and capable of replacing a tire for driving, and an application method thereof.

[0010] A tightening mechanism is provided in the middle where several of the arc plate assemblies are connected. The tightening mechanism includes a bottom plate, a cable winding wheel, a tightening worm, and a housing.

[0011] The cable winding wheel includes a cable winding cylinder and a worm gear. The cable winding cylinder is movably connected inside the housing. The worm gear is coaxial with and integrated with the cable winding cylinder. The tightening worm is movably connected in the housing in an upright state. The tightening worm meshes with the worm gear, and the rod head of the tightening worm extends out of the bottom surface of the bottom plate.

[0012] Radial through holes are provided on the cable winding cylinder, and the flexible cable passes through the through holes.

[0013] A rubber layer is laid on the outer surface of the arc plate.

[0014] The rocker arm is provided with a stabilizing mechanism or rollers;

[0017] The roller is hinged to the lower section of the rocker arm.

[0018] A rubber layer is provided at the bottom of the fork opening.

[0019] An application method of a tracked tire self-rescuer is carried out according to the following steps:

[0020] 1), Unfold the tracked tire self-rescuer into a strip shape and place it in the forward or backward direction of the faulty wheel;

After the faulty tire is squeezed and deformed, it shrinks and is accommodated between the support arm and the inner side of the arc plate, and the rocker arm is smoothly clamped into the flange of the wheel hub. After the crawler tire self-rescuer is tightened around the faulty tire, the support arm and the rocker arm are combined to act as spokes connecting the wheel hub and the arc plate, restoring the normal driving of the vehicle. During the use of the present invention, there is no need to disassemble the wheel and the tire, which is convenient, fast and labor-saving. Brief Description of the Drawings

[0043] The following further describes the present invention in conjunction with the attached Figure 1-16 The present invention includes a number of arc - plate assemblies. The arc - plate assembly includes an arc plate 1, a support arm 2, and a rocker arm 3. Hinge - connection structures are respectively provided at both ends of the arc plate 1; the support arm 2 is arranged vertically on both side edges of the arc plate 1; the middle of the rocker arm 3 is hinged to the upper end of the support arm 2, and a fork opening 31 is provided on the upper section of the rocker arm 3; thus, the arc - plate assembly is in a U - shape; the hinge - connection structures of adjacent arc - plate assemblies are connected in succession through hinge pins 12, and the connected arc - plate assemblies form a belt - like structure. Docking structures are respectively provided at the outer ends of the head - end arc - plate assembly and the tail - end arc - plate assembly, and a crawler - like shape is formed after docking. During use, the faulty tire 6 of the vehicle undergoes extrusion deformation, and the tire 62 shrinks and is accommodated between the support arm 2 and the inner side of the arc plate 1, and the rocker arm 3 is inserted into the hub flange 61 accordingly; after the crawler - type tire self - rescue device is tightened around the faulty tire 6, the support arm 2 and the rocker arm 3 are combined to act as the spokes connecting the hub and the arc plate 1, restoring the normal driving of the vehicle.

[0044] Embodiment 1 of the docking structure: It includes an upper tooth plate 41 and a lower tooth plate 42, and mutually - matching transverse ratchet surfaces 401 are respectively provided on the plate surfaces of the upper tooth plate 41 and the lower tooth plate 42. The ratchets on the upper tooth plate 41 and the lower tooth plate 42 can be stacked and interlocked up and down;

[0045] On the ratchet surfaces 401 of the upper toothed plate 41 and the lower toothed plate 42, grooves 403 and ridges 402 that can cooperate with each other are respectively provided. The grooves 403 and ridges 402 are perpendicular to the ratchet surfaces 401. The grooves 403 and ridges 402 can ensure that the docking structure will not undergo axial misalignment or even detachment due to vibration during vehicle driving, thus ensuring the driving safety of the vehicle.

[0046] On the ratchet surface 401 of the lower toothed plate 42, an inclined groove is provided. An inclined ejector block 421 is movably arranged in the inclined groove. When the inclined ejector block 421 receives an upward extrusion force from the ground, it can separate the ratchet surface 401 of the lower toothed plate 42 from the ratchet surface 401 of the upper toothed plate, facilitating the further tightening of the lower toothed plate 42 and the upper toothed plate 41 by using the friction between the vehicle and the ground, achieving a good wrapping property. The first embodiment of the docking structure is applicable to vehicles with a relatively large self-weight.

[0047] The second embodiment of the docking structure: It includes a flexible cable 54 passing through several arc plate assemblies. The head and tail ends of the flexible cable 54 respectively extend out of the outer ends of the head-end arc plate assembly and the tail-end arc plate assembly. A hook 542 is provided at the head end of the flexible cable 54, and a hanging ring 541 is provided at the tail end of the flexible cable 54;

[0048] A tightening mechanism is provided in the middle where several arc plate assemblies are connected in succession. The tightening mechanism includes a bottom plate 55, a cable winding wheel 53, a tightening worm 52, and a housing 51.

[0049] The cable winding wheel 53 includes a cable winding cylinder and a worm gear. The cable winding cylinder is movably connected in the housing 51. The worm gear is coaxial with and integrated with the cable winding cylinder. The tightening worm 52 is movably connected in the housing 51 in an upright state. The tightening worm 52 meshes with the worm gear. The rod head of the tightening worm 52 extends out of the bottom surface of the bottom plate 55. By manually buckling the hook 542 and the hanging ring 541, the tightening mechanism is used to tighten or loosen. The rod head is hidden in the rubber layer 11 on the outer surface of the bottom plate 55. The rubber layer 11 is provided with a through hole and is equipped with a plug at the position corresponding to the rod head. When it is necessary to tighten or loosen, the plug is removed, and a crank suitable for the rod head is used to tighten or loosen the flexible cable 54. The second embodiment of the docking structure is applicable to vehicles with a relatively light self-weight and relatively small wheel spokes.

[0050] Radial through holes are provided on the cable winding cylinder, and the flexible cable 54 passes through the through holes, facilitating the efficient and orderly winding or unwinding of the flexible cable 54 from the cable winding cylinder when the cable winding wheel 53 rotates.

[0051] The outer surface of the curved plate 1 is paved with a rubber layer 11. The rubber layer 11 is used to increase the friction between the curved plate 1 and the ground, which is more conducive to vehicle driving and more wear-resistant. The inner and outer surfaces of the curved plate 1 are provided with rib frames 14. The rib frame 14 on the outer surface is to have a larger contact area with the rubber layer 11 and enhance the connection strength between the rubber layer 11 and the curved plate 1; the rib frame 14 on the inner surface is to push the tire 62 toward the inner hollow direction of the tire 62, which is conducive to the contraction and accommodation of the tire 62 inside the crawler tire self-rescuer. The hinge pin 12 is provided with a waist-shaped hole, the long axis of which is parallel to the top surface of the curved plate 1, and an adjustment margin is provided to facilitate the vehicle to travel on bumpy roads.

[0052] The rocker arm 3 is provided with a stabilizing mechanism or a roller; the stabilizing mechanism includes a ratchet shaft 21 and a spring 22, the ratchet shaft 21 passes through the through hole of the support arm 2, and the side wall of the through hole is provided with a ratchet that matches the ratchet shaft 21, and one end of the ratchet shaft 21 on the inner side of the support arm 2 is hinged to the lower section of the rocker arm 3; the other end of the ratchet shaft 21 on the outer side of the support arm 2 is connected to the outer side of the support arm 2 through the spring 22; the roller is hinged to the lower section of the rocker arm 3. The stabilizing mechanism can prevent the fork 31 of the rocker arm 3 from shaking or even detaching from the hub flange 61 when the wheel is subjected to impact forces of varying sizes during the driving of the vehicle; the roller helps the tire 62 enter the crawler tire self-rescuer.

[0053] A rubber layer is provided at the bottom of the fork 31 , which helps to reduce the wear between the fork 31 and the hub flange 61 .

[0054] A method for applying a crawler tire self-rescuer is carried out according to the following steps:

[0055] 1) Unfold the crawler tire self-rescuer into a belt shape and place it in the forward or backward direction of the faulty wheel 6;

[0056] 2) The vehicle drives at a low speed, and after the faulty wheel 6 is rolled into one end of the crawler-type tire self-rescuer, the vehicle continues to drive until the crawler-type tire self-rescuer completely surrounds the faulty wheel 6;

[0057] 3) The docking mechanism of the crawler tire self-rescuer is a structure of an upper tooth plate 41 and a lower tooth plate 42, which is automatically locked by the friction of the vehicle; or the docking mechanism of the crawler tire self-rescuer is a soft rope 54, and the soft rope 54 is tightened by a tightening mechanism.

[0058] The present invention is not limited to the above-mentioned embodiments. On the basis of the technical solution disclosed in the present invention, technicians in this field can make some substitutions and deformations to some technical features therein according to the disclosed technical content without creative labor, and these substitutions and deformations are all within the protection scope of the present invention.
