Description

Technical Field

[0001] This utility model relates to the field of tire technology, and in particular to an emergency spare tire, wheel structure and automobile. Background Technology

[0002] As is well known, new energy vehicles typically do not come equipped with a spare tire. The main reasons for this are: 1. Limited interior space; 2. Reducing vehicle weight and saving energy consumption; 3. Improving space utilization, as eliminating the spare tire frees up more space in the trunk.

[0003] New energy vehicles are becoming increasingly popular in the ride-hailing market due to their environmental friendliness and energy efficiency. However, because new energy vehicles do not have spare tires, drivers are often helpless when they encounter a flat tire, especially in severe weather (storms, blizzards, icy roads) or when the flat tire is located in a remote area. It is often difficult to find a nearby tire repair shop, and choosing tow trucks or mobile tire repair shops can be expensive, increasing costs and making it unprofitable. This undoubtedly adds to the drivers' troubles.

[0004] A search revealed existing technologies that include solutions for emergency inner tubes, such as the tire with a built-in emergency inner tube disclosed in patent application number 202020080324.1. This patent provides technical guidance on setting up an emergency inner tube. Under normal circumstances, the emergency inner tube is in a vacuum state, secured to the rim by a fixing device, without affecting the normal operation of the tire. When the tire is damaged by a sharp object, causing a rapid drop in tire pressure and only a partial puncture, a certain pressure of gas can be injected into the emergency inner tube to function as an inner tube, temporarily converting the vacuum tire into an inner tube tire. While this solution is feasible, it requires a complete modification of the rim and tire, including drilling holes in the rim. It is a customized product, requiring all four wheels of the car to be replaced, increasing overall operating costs. Furthermore, drilling holes in the rim can negatively impact the wheel's safety performance. Additionally, this solution clearly cannot address the emergency situation after a tire blowout for existing vacuum tires, thus limiting its applicability.

[0005] Based on the above analysis and in light of the actual situation, it is necessary to seek a low-cost and universal emergency response method for tire blowouts in new energy vehicles with vacuum tires, hence this case. Utility Model Content

[0006] This utility model aims to solve, at least to a certain extent, the technical problems in related technologies. To this end, this utility model proposes an emergency spare tire, a wheel structure, and a vehicle.

[0007] The technical solution to the technical problem solved by this utility model is as follows:

[0008] Firstly, this technical solution proposes an emergency backup plan, including:

[0009] A ring-shaped main body; the ring-shaped main body is made of flexible material and has an inflatable cavity inside;

[0010] A dividing seam is provided on the annular body to divide the annular body; after division, the annular body has two ends, and the ends are closed ends; when the two ends are joined together, the annular body forms an annular shape;

[0011] An inflation tube; the inflation tube is made of flexible material, with one end connected to the ring-shaped main body and the other end detachably connected to an air valve.

[0012] Preferably, the annular body is made of rubber material.

[0013] Preferably, the inflation tube is connected to the inner side of the annular body.

[0038] Example 1:

[0039] like Figure 1 - Figure 4 As shown in the figure, this embodiment proposes an emergency spare tire, which is an inflatable structure, mainly including a ring-shaped body 1, an inflation tube 2, etc., which are described in detail below:

[0040] Ring-shaped body 1: The ring-shaped body 1 is made of a flexible material and has an inflatable cavity inside; in this embodiment, the ring-shaped body 1 is made of a rubber material, such as butyl rubber.

[0041] A dividing slit 101 is also provided on the annular body 1; the dividing slit 101 divides the annular body 1; after division, the annular body 1 has two ends, and the ends are closed ends; when the two ends are joined together, the annular body 1 forms an annular shape; it should be noted that by providing the dividing slit 101, the annular body 1 can be easily rolled up. When not in use, it can be folded up or rolled up from one end to form a storage structure.

[0042] Regarding the inflation tube 2: The inflation tube 2 is made of flexible material, which can be bent and rolled up; in this embodiment, the inflation tube 2 is preferably made of pressure-resistant flexible tubing; one end of it is connected to the annular body 1, and the other end is detachably connected to the valve 3. One end of the inflation tube 2 is connected to the interior of the annular body 1, and air can be inflated into the annular body 1 through the inflation tube 2.

[0043] The emergency spare tire proposed in this utility model, by setting a dividing seam 101, divides the original ring-shaped main body 1 into an arc-shaped strip structure, no longer a complete ring. The advantages of this setting are: firstly, it is convenient for car owners to store and organize the emergency spare tire, making it easy to carry and not taking up too much space; secondly, in emergency situations, it is easy to stuff into the tire 5, achieving the purpose of quick filling and quick handling.

[0044] In some feasible embodiments, the inflation tube 2 is connected to the inner side of the annular body 1; of course, the inflation tube 2 can also be connected to the outer side or the entire body. In this embodiment, it is preferably located on the inner side.

[0045] In some feasible embodiments, the inflation tube 2 has a flat structure, which is designed for ease of installation. The end of the inflation tube 2 furthest from the annular body 1 is connected to a first connecting portion 6. One end of the valve 3 has a second connecting portion 31, and the other end has an inflation portion 32 for easy connection to an air pump. The second connecting portion 31 is detachably connected to the first connecting portion 6, and the detachable connection method includes, but is not limited to, threaded connection, snap-fit, and plug-in connection. Specifically, in this embodiment, the first connecting portion 6 and the second connecting portion 31 are threadedly connected.

[0046] The flat design of the inflation hose 2 facilitates its passage through the gap between the tire 5 and the rim 4, eliminating the need to drill holes in the rim 4 and simplifying installation. The flexible material of the inflation hose 2 allows it to conform to the shape of the spare tire after inflation, maintaining a close fit and preventing protrusions that could irritate the tire. Furthermore, the flexible material of the inflation hose 2, with its easily deformable nature, helps ensure a tight seal between the tire 5 and the rim 4, guaranteeing proper installation and minimizing disruption.

[0047] In this embodiment, the first connecting part 6 is a connector made of rigid material, which facilitates connection with the valve stem 3. The connector and the inflation tube 2 are integrated to form a structure that combines rigidity and flexibility. The connector can be made of rigid plastic, and the inflation tube 2 can be made of flexible tubing such as rubber or silicone.

[0048] In this embodiment, the partition seam 101 is arranged at an angle, such as... Figure 2 As shown, the purpose of the oblique design is that when inflated, the two ends can interlock, and the oblique surface can automatically form a docking, creating a ring structure that is relatively stable.

[0049] Example 2:

[0050] like Figure 5-7 As shown, this embodiment proposes a wheel structure, including a hub 4, on which a tire 5 is mounted; an emergency spare tire is provided between the tire 5 and the hub 4; wherein, an annular body 1 is built into the tire 5 and attached to the surface of the hub 4; one end of the inflation tube 2 extends out of the tire 5 through the connection between the hub 4 and the tire 5, and is set in an exposed position, which facilitates installation and connection with the valve stem 3. The valve stem 3 can adopt a conventional structure, and there are many types available on the market; a suitable one can be selected.

[0051] Example 3:

[0052] This embodiment also proposes a car equipped with the aforementioned wheel structure.

[0053] Instructions for using an emergency spare tire:

[0054] When a tire blows out, bring the car to a stop. If there are any foreign objects (such as nails) on tire 5, remove them first to prevent puncturing the spare tire. Use a jack to lift the car. Use a tool (such as a crowbar) to push tire 5 inward, creating a gap between tire 5 and rim 4. Insert the spare tire into tire 5 through this gap. Specifically, hold both ends of the spare tire and push it downward through the gap into tire 5 until the entire annular body 1 of the spare tire 5 is inserted. One end of the inflation hose 2 extends outward through the connection between tire 5 and rim 4. Connect valve 3 to inflation hose 2 and connect the air pump to valve 3. Use the air pump to inflate the spare tire until the appropriate pressure is reached. The driver should then slowly drive the car to a repair shop for emergency use.

[0055] Application results:

[0056] The emergency spare tire proposed in this utility model has a simple structure, is easy to operate, and is inexpensive. When not in use, it can be rolled up and placed in the vehicle, taking up little space and being easy to store and carry. When a tire blowout occurs and emergency treatment is needed, the emergency spare tire is inserted into the tire 5 through the gap between the tire 5 and the rim 4, with one end of the inflation tube 2 left outside. Gas of a certain pressure is injected into the emergency spare tire through the inflation tube 2, which functions as an inner tube, temporarily transforming the vacuum tire 5 into an inner tube tire 5, making it convenient for the vehicle owner to drive to a repair shop in an emergency.

[0057] Although the specific embodiments of the utility model have been described above in conjunction with the accompanying drawings, this is not intended to limit the scope of protection of the utility model.
