[0001] The utility model relates to the technical field of spare tire lifting system design, in particular to a spare tire lifting system and a vehicle with the same. Background Art

[0002] The spare tire of a strong off-road vehicle needs to meet the high reliability of spare tire fixation and ensure a wide and flat trunk space, so the spare tire is generally fixed to the bottom of the vehicle body floor through a spare tire lifter. The fixing method generally uses a chain-type spare tire lifter to fix the spare tire. The chain-type spare tire lifter works away from the driving shaft to drive the chain to move up and down, thereby realizing the lifting of the spare tire. Since the chain in the chain-type spare tire lifter needs to be perpendicular to the ground, the shaft and the chain can only be arranged relatively vertically, resulting in the need for the arrangement direction of the shaft that controls the upper and lower positions of the spare tire in the chain-type spare tire lifter to be parallel to the ground. In view of this feature, the spare tire arrangement form of the chain-type spare tire lifter in passenger cars on the existing market all adopts a structural form of opening a hole in the rear bumper beam (or the side of the vehicle body) (the hole is used for the drive mechanism such as the rocker column to be transmitted from the outside and connected to the rotating shaft, and the rocker column is used to drive the rotating shaft), which has an adverse effect on the safety and aesthetics of the vehicle.

[0003] With respect to the above-mentioned problems in the prior art, no effective solution has been proposed yet. Utility Model Content

[0029] Now, exemplary embodiments according to the present application will be described in more detail with reference to the accompanying drawings. However, these exemplary embodiments may be implemented in a variety of different forms and should not be construed as being limited to the embodiments described herein. It should be understood that these embodiments are provided to make the disclosure of the present application thorough and complete, and to fully convey the concepts of these exemplary embodiments to those of ordinary skill in the art. In the accompanying drawings, for the sake of clarity, the thickness of the layers and regions may be enlarged, and the same reference numerals are used to represent the same devices, and thus their descriptions will be omitted.

[0030] An off-road vehicle, also known as an SUV (Sport Utility Vehicle), is a multi-purpose vehicle with powerful power and off-road capabilities. It combines the characteristics of a sedan and an off-road vehicle, and can not only travel comfortably on urban roads, but also cope with complex terrain and harsh road conditions.

[0031] Off-road vehicles usually have strong power: off-road vehicles are usually equipped with high-performance engines to provide enough power to adapt to different driving conditions. This allows off-road vehicles to travel easily on rugged terrain and cope with situations that require higher speeds. In order to cope with uneven road conditions, strong off-road vehicles usually have a higher ground clearance. This means that the bottom of the vehicle is at a greater distance from the ground, which can better pass obstacles such as raised roads, stones and tree roots. The vast majority of strong off-road vehicles are equipped with a four-wheel drive system, enabling them to drive all four wheels at the same time. This provides better traction and handling, allowing the vehicle to cope with slippery, muddy and rugged terrain.

[0032] In order to provide better driving comfort and control, strong off-road vehicles are usually equipped with a powerful suspension system, which can effectively absorb shock and keep the vehicle stable under bumpy road conditions.

[0033] Strong off-road vehicles can cope with various driving scenarios, whether it is urban roads, highways or rugged mountain roads. They can also meet special driving needs such as towing trailers, climbing steep slopes and crossing deep water.

[0034] Strong off-road vehicles usually have spacious interior space, which can accommodate more passengers and luggage. This makes off-road vehicles an ideal choice for activities such as family travel, hiking and camping.

[0035] Therefore, based on the above characteristics of strong off-road vehicles, the layout of their spare tires is also different from that of general vehicles. There are several types of spare tire layouts for off-road vehicles:

[0036] First, the spare tire under the floor. The spare tire is usually placed at the bottom of the vehicle, does not need to take up space inside the vehicle and is a hidden design;

[0037] Second, the spare tire is mounted at the rear. Some off-road vehicles have a shorter body and limited trunk space, so the spare tire is placed on the rack at the rear of the vehicle. This arrangement can save trunk space, but may have a certain impact on the line of sight;

[0038] Third, the spare tire on the roof. Some off-road vehicles have a special spare tire rack on the roof, and the spare tire is placed on the roof. This arrangement can avoid taking up space inside or behind the car, but it may increase the height of the car and wind resistance;

[0039] Fourth, side-mounted spare tire: Some off-road vehicles hang the spare tire on a bracket on the side of the vehicle body, which makes it easy to remove and replace the spare tire without taking up space inside or behind the vehicle, but it will damage the aesthetics of the vehicle.

[0040] In view of the characteristics of the above-mentioned spare tire layout, the spare tire under the floor has received more and more attention.

[0041] With the continuous development of high-end off-road vehicles, in order to solve the problem of vehicle appearance consistency and reduced safety caused by the spare tire arrangement method of passenger cars using a chain-type spare tire lifter, it is necessary to find a new spare tire arrangement method and develop related components to further improve the appearance consistency and safety quality of the entire vehicle while ensuring the reliability of spare tire fixation.

[0042] Combination Figures 1 to 3 As shown, according to a specific embodiment of the present application, a spare tire lifting system is provided.

[0043] The spare tire lifting system includes: a spare tire lifter 1, a socket head 2, and a ratchet wrench 3. The spare tire lifter 1 is connected to the mounting base. One end of the socket head 2 is detachably connected to the spare tire lifter 1. The ratchet wrench 3 is detachably connected to the other end of the socket head 2. When the ratchet wrench 3 is connected to the socket head 2, at least part of the ratchet wrench 3 is located in the cabin on top of the vehicle body floor 5. Operating the ratchet wrench 3 can drive the socket head 2 to rotate, so that the spare tire lifter 1 drives the spare tire 4 to rise or fall in the vertical direction.

[0044] By applying the technical solution of the present application, at least part of the ratchet wrench 3 is arranged in the cabin on top of the vehicle body floor 5, and the spare tire lifter 1 and the ratchet wrench 3 are connected by the socket head 2, so that the spare tire lifting system can realize that the ratchet wrench 3 can drive the spare tire 4 to rise or fall in the vertical direction, while avoiding the defect of drilling holes in the bumper beam or the vehicle body side panel in the prior art, ensuring the integrity and structural strength of the bumper beam or the vehicle body side panel, and also making the overall integration higher. The technical solution of the present application effectively solves the problem that the spare tire arrangement in the prior art damages the vehicle safety.

[0045] Preferably, both ends of the socket head 2 have matching structures, which may be embedding grooves, and the shapes of the embedding grooves are configured to match the shapes of the spare tire lifter 1 and the ratchet wrench 3 .

[0046] Preferably, the matching structures at both ends of the socket head 2 are connected with the spare tire lifter 1 and the ratchet wrench 3 by interference fit.

[0047] Furthermore, the spare tire lifter 1 comprises: a rotating shaft, which is rotatably connected to the mounting base through a bearing, and a sleeve is arranged on the rotating shaft; a traction member, one end of which is connected to the sleeve, and the traction member has a retracted state in which it is at least partially retracted in the sleeve, and a fully straightened released state; and a spare tire mounting member, which is connected to the other end of the traction member. This arrangement can reduce the space occupied by the spare tire lifter 1 and improve the overall integration of the system.

[0048] The sleeve is configured as a hollow cylindrical structure, which is different from the structure of the sleeve head 2. The sleeve is sleeved on the outside of the rotating shaft.

[0049] Specifically, the spare tire mounting member has a hidden position for driving the spare tire 4 to move to the spare tire space at the bottom of the vehicle, and an exposed position for driving the spare tire 4 to move to the disassembly area. When the traction member is in a retracted state, the spare tire mounting member is located at the hidden position, and when the traction member is in a released state, the spare tire mounting member is located at the exposed position. The spare tire space refers to the space formed between the underside of the vehicle floor and the ground, and the spare tire 4 is usually suspended under the floor.

[0050] The spare tire mounting member may be configured as a plate-shaped stamped sheet metal structure, or may be a connection structure formed by a plurality of plates, and the spare tire mounting member is used to mount the spare tire 4 .

[0051] Furthermore, the traction member is arranged to extend in the vertical direction, and the rotating shaft is arranged to extend in the horizontal direction. This arrangement can ensure the movement accuracy of the spare tire 4, which only maintains vertical up and down movement under the action of gravity without mechanical interference with other components.

[0052] Furthermore, the ratchet wrench 3 has a connection portion connected to the socket head 2 and a grip portion connected to the connection portion, the connection portion is located at the bottom of the vehicle body floor 5, the grip portion is located in the vehicle cabin at the top of the vehicle body floor 5, and an opening is opened on the vehicle body floor 5. When the ratchet wrench 3 is connected to the socket head 2, the grip portion is inserted into the opening. The opening is preferably a strip-shaped long hole, and the operation of the grip portion can drive the socket head 2 to rotate, so that the spare tire lifter 1 drives the spare tire 4 to rise or fall in the vertical direction.

[0053] The operation of the grip portion refers to rotating the grip portion, which is limited by the size of the opening and the single rotation stroke is also limited. The rotation of the drive shaft can be achieved through multiple rotations, thereby controlling the contraction or release of the chain.

[0054] Further, the socket head 2 is coaxially arranged with the rotating shaft, and the axis of the gripping portion is perpendicular to the axis of the socket head 2. This arrangement can facilitate the arrangement of the ratchet wrench 3 so that it can be integrated into the vehicle.

[0055] The spare tire lifting system also includes a buckle device, which is connected to at least one of the rotating shaft and the traction member. The buckle device has a locking position for locking the traction member at a current position, and an unlocking position for releasing the traction member.

[0056] For example, the buckle device includes a locking seat and a locking buckle, the traction member is movably arranged in the locking seat, and when the locking buckle is combined with the locking seat, the traction member is fixed to the locking seat.

[0057] Furthermore, the traction member is a chain or a steel wire rope. The traction member can also be made of a material such as a polymer material with strength that meets the requirements.

[0058] Furthermore, the installation base is the vehicle body floor 5 or the frame crossbeam. That is, the frame crossbeam or the vehicle body floor is screwed to fix the chain-type spare tire lifter, and a spare tire lifter operation port (i.e., opening) is opened at a position of the vehicle body floor near the rotation axis of the chain-type spare tire lifter. This arrangement can improve the installation stability of the spare tire lifting system.

[0059] Using the technical solution of the present application, a method for using the spare tire lifting system is also provided, the method comprising:

[0060] 1. Install the special socket head 2 onto the ratchet wrench 3, and then clamp the special socket head 2 to the rotating shaft of the chain-type spare tire lifter 1;

[0061] 2. The ratchet wrench 3 drives the special socket head 2 to rotate, and then drives the chain-type spare tire lifter rotating shaft to rotate, so as to adjust the upper and lower positions of the spare tire.

[0062] According to a specific embodiment of the present application, a vehicle is provided, including a spare tire lifting system, and the spare tire lifting system is the spare tire lifting system in the above embodiment.

[0063] The spare tire lifting system can be manual or automatically controlled.

[0064] For example, the structure of the automatically controlled spare tire lifting system includes the following parts:

[0065] 1. Chain: The chain is an important component connecting the spare tire lifting device and the mounting bracket. The spare tire is lifted and lowered by the rotation of the chain.

[0066] 2. Motor: The motor is the power source that drives the chain to rotate. It converts electrical energy into mechanical energy to drive the chain to lift and lower the spare tire.

[0067] 3. Gear: The gear is the transmission device between the motor and the chain. Through the rotation of the gear, the motor speed and torque are transmitted to the chain to realize the lifting and lowering of the spare tire.

[0068] 4. Bracket: The bracket is the part that loads the spare tire. It raises or lowers the spare tire from the bottom of the car by raising and lowering the chain to facilitate replacement or storage of the spare tire.

[0069] The working principle of the automatic chain spare tire lifter is as follows:

[0070] 1. When the spare tire is needed, the driver starts the spare tire lifter through the control button in the car.

[0071] 2. The motor starts working, converting electrical energy into mechanical energy through gear transmission to drive the chain to rotate.

[0072] 3. The chain begins to rise, lifting the spare tire on the bracket from under the vehicle to a specific position under the vehicle.

[0073] 4. The driver can remove the spare tire and replace or repair it.

[0074] 5. When the spare tire needs to be stored, put the spare tire back into the bracket and start the spare tire lifter using the control button.

[0075] With the chain-type spare tire lifter, the driver can easily replace and store the spare tire, improving the convenience and safety of vehicle use.

[0076] From the above description, it can be seen that the above embodiments of the utility model achieve the following technical effects:

[0077] The present application proposes a spare tire arrangement for a passenger car using a chain-type spare tire lifter. By adjusting the position of the spare tire lifter as a whole vehicle, adding a spare tire lifter operating port to the vehicle body floor, and adopting a special sleeve head and other measures, the spare tire can be conveniently and reliably taken out and placed. There are no openings on the side of the vehicle body and no openings on the rear bumper beam, thereby ensuring the consistency of the appearance and safety quality of the entire vehicle.

[0078] By adopting the technical solution of the present application, by adjusting the position of the spare tire lifter as a whole vehicle, adding a spare tire lifter operating port and a special sleeve head to the floor of the vehicle body and other measures, it is possible to achieve no openings on the side of the vehicle body and no openings on the frame crossbeam, thereby effectively ensuring the consistency of the vehicle's appearance and the strength of the whole vehicle. In addition, through experiments and verification, the removal time of this spare tire arrangement is basically the same as that of the traditional spare tire arrangement using a chain-type spare tire lifter, and it has been applied to a certain vehicle model. After road tests such as comprehensive vehicle durability, enhanced bad road durability and regional adaptability tests, it has been verified that the life of related components of this spare tire arrangement can reach 1.5 times that of the traditional arrangement.
