In addition, the terms "first", "second", and "third" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0042] Combine the following Figures 1 to 6 The utility model is described as a spare tire storage device.

[0043] like Figure 1 As shown, the utility model provides a spare tire storage device for storing a spare tire 100, comprising a spare tire bracket 1, a hoisting mechanism 2, a sling 3, a limiting member 4 and a clamping member 5.

[0044] Among them, the spare tire bracket 1 provides an installation foundation for the lifting mechanism 2 and provides stable support. The spare tire bracket 1 can be fixed to the operating machine by welding or bolts. The lifting mechanism 2 is arranged on the spare tire bracket 1, and is used to connect and support the sling 3. The top of the sling 3 is connected to the lifting mechanism 2, and the bottom end of the sling 3 passes through the spare tire bracket 1 and the spare tire 100; the function of the sling 3 is to bear the weight of the spare tire 100 and to lift and lower the spare tire when necessary. Its material should have sufficient strength and durability to cope with long-term use and possible wear and tear. The limiter 4 is arranged at the bottom end of the sling 3; the clamping member 5 is detachably connected to the limiter 4, and the clamping member 5 is in contact with the bottom of the spare tire 100.

[0045] The stopper 4 can switch between a first working state and a second working state. In the first working state, the stopper 4 penetrates the clamping member 5 and is clamped to the bottom of the clamping member 5, the sling 3 rises, and the top of the spare tire 100 contacts the bottom of the spare tire bracket 1, that is, the spare tire 100 rises under the joint action of the sling 3, the stopper 4 and the clamping member 5 until the spare tire 100 is clamped between the spare tire bracket 1 and the clamping member 5, so that the spare tire 100 is in a storage state. In the second working state, the stopper 4 is separated from the clamping member 5, the clamping member 5 no longer fixes the spare tire 100, and the spare tire 100 can be freely raised or lowered or taken out. The switching of this state is usually achieved by adjusting the connection relationship between the limit member 4 and the clamping member 5. Compared with the prior art that requires removing multiple bolts, the operation is simple, safe and reliable, and the spare tire can be quickly disassembled and assembled. Moreover, compared with the prior art that uses a fixed bracket to fix the spare tire, multiple spare tires 100 can be set through the above structure to meet the user's requirements for the number of spare tires 100. When multiple tires of the operating machinery are damaged, the spare tire 100 is replaced to meet the different needs of users.

[0046] The hoisting mechanism 2 can be an electric lifting mechanism, which can save manpower and improve the degree of automation compared to the manual lifting in the prior art. The sling 3 can be a steel wire rope, and the clamping member 5 can be made of aluminum or steel.

[0047] like Figure 2As shown, in one embodiment of the utility model, the clamping member 5 is provided with a through hole 10 and a sling sliding hole 20 that are connected to each other, wherein the through hole 10 is for the limiter 4 to pass through, and when the limiter 4 needs to be fixed at the bottom of the clamping member 5, it will pass through the through hole 10 and form a snap-fit ​​relationship with the clamping member 5. This design ensures a stable connection between the limiter 4 and the clamping member 5, thereby ensuring the stability of the spare tire 100 when stored. The sling sliding hole 20 is only for the sling 3 to pass through, and the size of the sling sliding hole 20 is larger than the size of the sling and smaller than the size of the limiter 4, and one end of the through hole 10 is located at the center of the clamping member 5, and the other end is provided with a sling sliding hole 20. The shape and size of the sling sliding hole 20 allow the sling 3 to move in the sling sliding hole 20, and only allow the sling 3 to pass through, and do not allow the limiter 4 to pass through, so as to ensure that when the spare tire 100 is in the first working state, corresponding to the storage state of the spare tire 100, the limiter 4 can be clamped at the bottom of the sling sliding hole 20, thereby realizing the clamping connection between the limiter 4 and the clamping member 5. Generally speaking, the sling sliding hole 20 is set as a long strip hole.

[0048] like Figure 3 and Figure 4 As shown, in one embodiment of the utility model, a limiting groove 30 is further provided at the bottom of the clamping member 5, and the limiting groove 30 is connected with the sling sliding hole 20, and the shape of the limiting groove 30 is adapted to the limiting member 4. The main function of the limiting groove 30 is to cooperate with the limiting member 4 to ensure the stability of the spare tire 100 during storage. When the limiting member 4 passes through the through hole 10 and is engaged with the bottom of the clamping member 5, the limiting member 4 will enter the limiting groove 30 at the same time. Since the shape of the limiting groove 30 is adapted to the limiting member 4, this design can ensure the stability and firmness of the limiting member 4 at the engaged position, and prevent it from falling off due to vibration or external force. The design that the limiting groove 30 is connected with the sling sliding hole 20 enables the sling 3 to pass through the clamping member 5 smoothly during the lifting process. The sling 3 can not only pass through the sling sliding hole 20, but also enter the limiting groove 30, providing sufficient space for the lifting and lowering of the spare tire 100. This design not only reduces friction and resistance, but also improves the reliability and durability of the device.

[0049] By combining the design of the through hole 10, the sling sliding hole 20 and the limiting groove 30, the clamping member 5 can flexibly adapt to the requirements of different working states. In the first working state, the limiting member 4 passes through the clamping member 5 and is clamped in the limiting groove 30 to ensure the stable storage of the spare tire; in the second working state, the limiting member 4 is separated from the clamping member 5, and the spare tire 100 can be freely raised or lowered or taken out.

[0050] like Figure 1 and Figure 3As shown, in one embodiment of the utility model, the limit member 4 is spherical, and the limit groove 30 is set to be hemispherical. The spherical limit member 4 has a rounded surface and can easily slide in and out of the limit groove 30. This design makes the operation simpler and faster when the spare tire needs to be adjusted or replaced. Once the spherical limit member 4 is inserted into the hemispherical limit groove 30, due to the characteristics of the spherical shape, it can automatically adjust its position and find the most stable clamping point. This adaptability ensures the stability of the spare tire 100 during storage. Compared with limit members of other shapes, the spherical limit member 4 has a more uniform contact surface with the limit groove 30 during the clamping and separation process, which reduces the wear caused by friction and prolongs the service life.

[0051] In some feasible embodiments, the limiting member 4 can also be configured as a hook or other structural forms, as long as it can penetrate the clamping member 5 and clamp the spare tire 100 .

[0052] like Figure 2 , Figure 3 and Figure 4 As shown, in one embodiment of the utility model, the top surface of the clamp 5 is set to be circular, and the diameter of the clamp 5 is larger than the inner hole diameter of the spare tire 100. When the diameter of the clamp 5 is larger than the inner hole diameter of the spare tire 100, the clamp 5 can more firmly support the bottom of the spare tire 100 to prevent the spare tire 100 from shaking or falling off during storage or retrieval. The inner hole diameters of spare tires 100 of different sizes may be different. The larger diameter design of the clamp 5 allows it to adapt to more types of spare tires 100, thereby improving the versatility of the device. The circular shape makes it easier for the clamp 5 to align with the bottom of the spare tire, and the user can achieve stable clamping without precisely adjusting the angle, thereby improving the convenience of operation.

[0053] like Figure 1 , Figure 5 and Figure 6As shown, in one embodiment of the utility model, a positioning column 6 is further included, which is arranged at the bottom of the spare tire bracket 1. The positioning column 6 can be welded to the spare tire bracket 1, and in the first working state, the positioning column 6 is located at the inner hole of the spare tire 100, and a through hole 40 is opened at the center of the positioning column 6, and the through hole 40 is passed through by the sling 3. The positioning column 6 is arranged at the bottom of the spare tire bracket 1, and its main function is to ensure that the spare tire 100 can be accurately positioned in the first working state. When the spare tire 100 is stored, the positioning column 6 will naturally be located at the inner hole of the spare tire 100. This design not only helps the accurate alignment of the spare tire 100, but also prevents the spare tire 100 from moving or shaking in the horizontal direction during storage. A through hole 40 is opened at the center of the positioning column 6, and this design allows the sling 3 to pass through. The existence of the through hole 40 ensures that the sling 3 will not be hindered by the positioning column 6 when lifting the spare tire, thereby ensuring the smoothness of the operation. At the same time, due to the cooperation between the through hole 40 and the sling 3, the positioning column 6 can also guide and stabilize the sling 3 to a certain extent, preventing the sling 3 from being offset or twisted during the lifting process. By combining the design of the positioning column 6 and the through hole 40, the spare tire storage device is more perfect in structure and more comprehensive in function. The presence of the positioning column 6 makes the storage of the spare tire more stable and reliable, while the design of the through hole 40 ensures the normal use of the sling 3. The combination of the two not only improves the safety of the device, but also ensures the convenience of operation.

[0054] In one embodiment of the utility model, the positioning column 6 is trapezoidal along its axial section, is set as a truncated cone structure and has a wide end and a narrow end, the wide end is connected to the spare tire bracket, and the narrow end is set toward the limiter 4. This progressive structure enables the spare tire 100 to gradually cooperate with the positioning column 6 during the placement process to achieve more accurate positioning. The narrow end of the positioning column 6 is set close to the limiter 4 to better adapt to the inner hole structure of the spare tire 100. The inner hole of the spare tire 100 is usually a circular space. Placing the narrow end close to the spare tire 100 can ensure that the positioning column 6 can smoothly enter the inner hole of the spare tire 100 to achieve accurate positioning. At the same time, the narrow design of the narrow end also reduces the friction with the inner hole of the spare tire 100, making the placement and removal of the spare tire 100 smoother. The wide end is connected to the bottom of the spare tire bracket 1, providing a larger support area, thereby enhancing the stability of the entire device. Even under vibration or external force, the spare tire 100 can maintain a stable storage state.

[0055] See again Figure 5 and Figure 6As shown, in one embodiment of the utility model, the hoisting mechanism 2 includes a switch module 21, a power module 22 and a cable drum 23. The switch module 21 and the power module 22 are both arranged on the spare tire bracket 1, and the switch module 21 is electrically connected to the power module 22; the switch module 21 is responsible for receiving the user's operating instructions, such as start, stop, etc., and converting these instructions into electrical signals and transmitting them to the power module 22. The power module 22 is the power source of the hoisting mechanism 2, and is responsible for converting electrical energy into mechanical energy to drive the lifting and lowering movement of the sling 3. The power module 22 may adopt a driving mode such as an electric motor or a hydraulic motor, and the specific selection should be determined according to actual needs and working environment. The cable drum 23 is connected to the power module 22, and is used to receive the power of the power module 22, and the cable drum 23 is used to wind the sling 3, and is used to wind the sling 3. It plays the role of arranging cables and preventing cables from being entangled, while ensuring that the sling 3 can move smoothly during the lifting process. The design of the cable drum 23 should take into account the length and diameter of the cable to ensure that it can accommodate enough cables and allow the cables to be released freely when needed.

[0056] The switch module 21 may include a control switch and a controller, as long as the power module 22 can be turned on and off. The control switch may be arranged on the front of the panel of the spare tire bracket 1, and the controller may be arranged on the back of the panel of the spare tire bracket 1.

[0057] like Figure 5 and Figure 6 As shown, in one embodiment of the utility model, the hoisting mechanism 2 also includes a protective cover 24, which is arranged on the top of the spare tire bracket 1, and a power module 22 is arranged inside the protective cover 24. One end of the cable drum 23 is connected to the power module 22 for receiving the power of the power module 22, and the other end of the cable drum 23 is rotatably connected to the protective cover 24. The protective cover 24 is arranged on the top of the spare tire bracket 1. The arrangement of the protective cover 24 can not only effectively protect the power module 22 located inside it, and prevent it from being directly affected by the external environment, such as rain, dust, direct sunlight, etc., but also reduce damage or failure caused by external factors, thereby extending the service life of the power module 22.

[0058] At the same time, by placing the power module 22 in the protective cover 24, the entire hoisting mechanism can be made to look neater and more orderly, and it is also convenient for users to perform daily maintenance and care. The protective cover 24 can usually be made of steel plates spliced ​​together, or it can be integrally formed by a mold.

[0059] In summary, the spare tire storage device provided by the utility model, when the spare tire needs to be replaced, that is, when entering the second working state from the first working state, click the switch module 21 to turn on the power module 22, the power module 22 drives the cable drum 23 to rotate to loosen the sling 3, the sling 3 and the spare tire 100 descend, and stop when they descend to the ground, pass the limit member 4 through the through hole 10 of the clamping member 5, take out the clamping member 5, and finally take out the spare tire 100 for replacement.

[0060] When the spare tire needs to be stored, that is, when entering the first working state from the second working state, the spare tire 100 is placed flat on the clamping member 5, the sling 3 and the limiting member 4 pass through the middle hole of the spare tire 100, the limiting member 4 passes through the through hole 10, moves along the sling slide hole 20, and enters the limiting groove 30 at the bottom of the clamping member 5, click the switch module 21 to turn on the power module 22, the power module 22 drives the cable drum 23 to reverse to tighten the sling 3, and under the action of the gravity of the spare tire 100 and the traction force of the sling 3, the clamping member 5 clamps the spare tire 100 until it rises to the positioning column 6, and the positioning column 6 is located at the middle hole of the spare tire 100 to prevent the spare tire 100 from shaking when stored.
