[0027] The following describes the specific embodiments of the present disclosure in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present disclosure and are not intended to limit the present disclosure.

[0028] In the present disclosure, unless otherwise stated, "inside" and "outside" refer to the inside and outside of the corresponding component outline. In addition, the directional words "above" and "below" used in the present disclosure can refer to Figure 1 In addition, when the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.

[0029] according to Figures 1 to 4 As shown, an embodiment of the present disclosure provides a vehicle (e.g., a passenger car), which may include a vehicle body 1 and a spare tire lifting mechanism 2. The vehicle body 1 may include a accommodating cavity 10 with a downward opening. The spare tire lifting mechanism 2 is arranged in the accommodating cavity 10 to protect the spare tire lifting mechanism 2 and the spare tire 8. The spare tire lifting mechanism 2 may include a driving member 21 and a transmission mechanism. The transmission mechanism may include a rotating shaft 22 connected to the output end of the driving member 21 and a traction assembly 20 arranged on the rotating shaft 22. The traction assembly 20 is used to raise or lower the spare tire 8 so that the spare tire 8 can enter and exit the accommodating cavity 10 from the opening of the accommodating cavity 10, making it convenient for an operator to take the spare tire 8. The driving member 21 is used to drive the rotating shaft 22 to rotate around its own central axis to drive the traction assembly 20 to raise or lower the spare tire 8.

[0030] Through the above technical solution, a accommodating cavity 10 is provided on the vehicle body 1, and the operator can drive the spare tire 8 in and out of the accommodating cavity 10 through the spare tire lifting mechanism 2 provided in the accommodating cavity 10, so that during driving of the vehicle, the spare tire 8 and the spare tire lifting mechanism 2 located in the accommodating cavity 10 will not be damaged by collisions due to the road environment or the harsh surrounding environment (such as rugged mountain roads, forest roads, etc.), thereby achieving protection for the spare tire 8 and the spare tire lifting mechanism 2, and being safer and more reliable in use.

[0031] In some embodiments, for example, referring to Figure 1As shown, the accommodating cavity 10 may be located below the cab 11 of the vehicle body 1 to facilitate the operator to take the spare tire 8 .

[0032] In some embodiments, for example, referring to Figures 1 to 3 As shown, the vehicle body 1 may include a frame 30 and a mounting bracket 31. The accommodating cavity 10 is located below the frame 30 at the front of the vehicle and on the inner side of the outer peripheral plate of the front of the vehicle. The mounting bracket 31 is at least partially located in the accommodating cavity 10 and connected to the frame 30. The driving member 21 may include a driving motor 210 drivingly connected to the rotating shaft 22. The mounting bracket 31 is used to fix the driving motor 210. By providing the driving motor 210, the spare tire 8 can be electrically raised and lowered, saving manpower and being more convenient.

[0033] The structure of the mounting bracket 31 can be adaptively adjusted according to actual needs. For example, the mounting bracket 31 can be configured to cover the housing of the drive motor 210, and the housing can be connected to the mounting bracket 31 via connecting bolts. The mounting bracket 31 can also be configured as a "mouth"-shaped or hollow cylindrical frame structure. The present disclosure is not limited thereto.

[0034] In some embodiments, for example, referring to Figures 1 to 3 As shown, the traction assembly 20 may include a sprocket 200 disposed on a rotating shaft 22 and a chain 201 wound around the sprocket 200. The output end of the drive motor 210 may be connected to one end of the rotating shaft 22 via a connecting flange 6. The sprocket 200 and chain 201 are provided to improve load-bearing capacity, prevent the spare tire 8 from being separated from the chain 201 due to bumps and vibrations during vehicle movement, and provide greater stability and safety.

[0035] The structure of the traction assembly 20 can be adaptively adjusted according to actual needs. For example, the traction assembly 20 can further include a rope drum disposed on the rotating shaft 22 and a rope wound around the rope drum. This disclosure does not specifically limit this.

[0036] The driving motor 210 and the rotating shaft 22 may be connected in any suitable manner, for example, the driving motor 210 and the rotating shaft 22 may be connected via a coupling, but the present disclosure is not limited thereto.

[0037] In some embodiments, for example, referring to Figures 1 to 3As shown, the spare tire lifting mechanism 2 may further include a spare tire bracket 5 connected to the chain 201. The spare tire bracket 5 is used to connect to the spare tire 8. A limit switch 4 is provided on the frame 30. The limit switch 4 is connected to the drive motor 210 for signal communication. The limit switch 4 is located above the spare tire bracket 5 to limit the maximum point of upward movement of the spare tire bracket 5. The limit switch 4 is used to limit the travel distance of the spare tire 8 during lifting. During the lifting process, the spare tire 8 contacts the limit switch 4 provided on the frame 30, which can shut off the drive motor 210 to prevent the spare tire 8 from colliding with the frame 30, further improving safety.

[0038] Optionally, the vehicle body 1 may further include a control switch for controlling the drive motor 210 , and the control switch is located in the cab 11 .

[0039] It should be noted that, for example, Figure 4 As shown, the drive motor 210 of the present disclosure can be a brushed motor. The drive motor 210 is controlled by a control switch (for example, the control switch can be a three-way switch 12) to control forward rotation, reverse rotation, and stop of the drive motor 210. When the drive motor 210 rotates forward, the spare tire 8 can be raised, and when the drive motor 210 rotates reversely, the spare tire 8 can be lowered. The limit switch 4 is used to shut off the drive motor 210 when the spare tire 8 is raised to a preset height. In this way, when the operator needs to lower the spare tire 8, they can operate the control switch in the cab 11 to reverse the drive motor 210, lowering the spare tire 8, and automatically resetting the limit switch 4 provided on the frame 30. This further improves the operability of the spare tire lifting mechanism 2.

[0040] The spare tire bracket 5 can be detachably connected to the chain 201. For example, a hook can be provided at the end of the chain 201, and the spare tire bracket 5 can be provided with a connecting portion that can cooperate with the hook. The connecting portion can be configured as a lifting ring. In this way, when installing the spare tire 8, the spare tire bracket 5 can be placed on one side of the spare tire 8, and the chain 201 passes through the wheel hub of the spare tire 8 from the other side to connect to the spare tire bracket 5. The spare tire bracket 5 can also be integrally constructed with the chain 201. The spare tire bracket 5 can be configured as a plate-type structure provided with connecting bolts, and the spare tire bracket 5 and the spare tire 8 are assembled by connecting bolts. The present disclosure is not limited to this, and those skilled in the art can make adaptive adjustments according to actual needs.

[0041] In some embodiments, for example, referring to Figure 3As shown, the driving member 21 may further include a rocker 211, which may be connected to the other end of the rotating shaft 22 away from the driving motor 210 via a fixing member 7. By providing the rocker 211, the operator can avoid raising and lowering the spare tire 8 by using the rocker 211 when the vehicle's mobile power supply is low, thereby improving operability and further enhancing the flexibility of the spare tire lifting mechanism 2.

[0042] Optionally, to facilitate disassembly and installation, the other end of the rotating shaft 22 may be provided with a slot for inserting the rocker 211, the fixing member 7 may be constructed as a locking pin, and the rocker 211 may be provided with a jack for the locking pin to pass through the rocker 211 and the slot.

[0043] The fixing member 7 may be constructed in any suitable form. For example, the fixing member 7 may also be constructed as a bolt and a nut, which is not specifically limited in the present disclosure.

[0044] In some embodiments, for example, referring to Figure 3 As shown, the rocker 211 has a connection portion 2110 for connecting an external tool, facilitating rotation of the rocker 211 by an operator. For example, the connection portion 2110 can be configured as a slot having a vertically extending slot. The external tool can be configured as, for example, an L-shaped lever, one end of which is provided with a protrusion that fits into the slot. The protrusion also has a block that fits into the slot. This provides circumferential positioning of the rocker 211 and the L-shaped lever, allowing them to rotate synchronously. The connection between the L-shaped lever and the rocker 211 allows the operator's operating end (the other end of the L-shaped lever, away from the rocker 211) to be located outside the vehicle body 1, facilitating operation. After the operation is completed, the L-shaped lever can be stored. Alternatively, the connection portion 2110 can be configured as a slot, such as a hexagonal or octagonal socket for a wrench to be inserted into. Accordingly, the external tool can be an extended wrench. The present disclosure is not limited to this. Those skilled in the art can make adaptive adjustments according to actual needs.

[0045] In some embodiments, for example, referring to Figure 1 As shown, the rotating shaft 22 and the rocker 211 can both extend along the width direction of the vehicle body 1. This facilitates operation from one side of the width direction of the vehicle body 1 using an external tool. The side of the width direction of the vehicle body 1 provides a larger and more convenient operating space than the front of the vehicle body 1, thereby further facilitating the operator to manually control the raising and lowering of the spare tire 8 using the rocker 211.
