[0001] The utility model relates to the field of vehicle components, and particularly relates to a spare tire lifting frame. Background Art

[0002] When the original tires of a vehicle cannot be used any more due to various reasons (such as air leakage, damage, etc.), the spare tire replacement system allows the driver to quickly replace the spare tire, ensuring that the vehicle can continue to drive to a safe location or a repair shop, thus avoiding the vehicle from being stalled on the road due to tire failure and reducing potential safety risks.

[0003] Since the position for installing the spare tire at the rear end of some vehicle bodies is occupied by other components, therefore, some equipped vehicles generally cancel the spare tire or install the spare tire at the rear side of the cab through a spare tire lifting system. When the spare tire needs to be replaced, the spare tire is quickly removed from the vehicle body through the lifting system. The lifting system fixes the spare tire on the rotating arm through front and rear chucks and multiple long studs. When disassembling the spare tire, a large wrench is needed to disassemble the stud nuts and the heavy chuck, and then the spare tire is removed manually. When reinstalling, the chuck also needs to be accurately aligned with the spare tire hub. The overall installation and disassembly process is cumbersome, consuming a large amount of manpower and being relatively inconvenient to use. Summary of the Utility Model

[0004] This application provides a spare tire lifting frame, which can solve the technical problems existing in the prior art that when replacing a spare tire with a common spare tire lifting system, it is necessary to first disassemble the spare tire and then move the spare tire to the ground, resulting in a cumbersome overall installation and disassembly process, relatively inconvenient use, and low replacement efficiency.

DETAILED DESCRIPTION

[0024] In order to enable those skilled in the art to better understand the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0025] The embodiment of the present application provides a spare tire lifting stand, which can solve the technical problems existing in the prior art. When replacing the spare tire, the commonly used spare tire lifting system needs to first remove the studs and other connecting parts used to fix the spare tire, and then move the spare tire to the ground, resulting in a cumbersome overall installation and removal process, inconvenient use, and low replacement efficiency.

[0026] The spare tire lifting frame provided in the present application includes a fixed component and a rotating component. The fixed component is stably connected to the vehicle body. During the driving of the vehicle, the spare tire is placed on the fixed component. The rotating component and the fixed component are hinged. The rotating component can rotate in a direction away from the fixed component with the fixed component as the center. At the same time, the rotating component is connected to the spare tire using a connecting piece. When the spare tire needs to be replaced, the rotating component starts to move and drives the spare tire to separate from the fixed component. After the spare tire is directly transferred from the vehicle to the ground, the connection between the rotating component and the spare tire can be released.

[0027] Specifically, Figure 1 A schematic diagram of a spare tire lifting frame structure provided in an embodiment of the present application is shown in FIG. Figure 1 As shown, the fixing assembly includes a tire limit frame 1 and a reaction force bracket 2 located at one end of the tire limit frame 1. When the vehicle is driving, the spare tire is placed on the tire limit frame 1. The tire limit frame 1 can limit the spare tire while carrying it, preventing the spare tire from shaking violently with the vehicle. The reaction force bracket 2 is fixedly connected to the tire limit frame 1 to form a whole.

[0028] The rotating assembly includes a slewing frame 3 and a telescopic unit 4. The bottom of the slewing frame 3 is hinged to the free end of the tire limiting frame 1, and a first tire connecting belt 5 is provided at the top of the slewing frame 3. The two ends of the telescopic unit 4 are respectively hinged to the slewing frame 3 and the reaction support 2.

[0029] Combined with the above description, one end of the tire limiting frame 1 is fixedly connected to the reaction support 2, and the other end is hinged to the bottom of the slewing frame 3. A first tire connecting belt 5 is provided at the top of the slewing frame 3. The spare tire is detachably connected to the slewing frame 3 through the first tire connecting belt 5. When the assembly is completed, the spare tire is located in the space formed by the tire limiting frame 1, the reaction support 2, and the slewing frame 3. The telescopic unit 4 is the power source for the rotation of the slewing frame 3. When the telescopic unit 4 extends, the slewing frame 3 drives the spare tire to move away from the tire limiting frame 1 until the spare tire gradually descends from the vehicle to the ground. Disconnecting the connection between the rotating assembly and the spare tire can start the tire changing work.

[0030] The tire limiting frame 1 in the spare tire lifting frame provided by the present application can fix and limit the spare tire. Cooperating with the first tire connecting belt 5, it can stably fix the position of the spare tire and prevent the spare tire from falling during driving. At the same time, the first tire connecting belt 5 also replaces the bolts and studs in the traditional lifting system, reducing the installation and disassembly process. When the spare tire needs to be replaced, the telescopic unit 4 drives the slewing frame 3 to transport the tire to the ground. The overall operation is simple and can greatly improve the convenience of the spare tire installation and disassembly work.

[0031] Specifically, Figure 2 is a structural detail diagram of a spare tire lifting frame provided by an embodiment of the present application. As Figure 2 shown, the tire limiting frame 1 includes a placement bottom plate 101 and two obliquely braced rods 102 arranged at intervals. The two ends of the obliquely braced rod 102 are respectively connected to one side edge of the placement bottom plate 101 and the same side edge of the reaction support 2.

[0032] The placement bottom plate 101 is horizontally arranged, and the reaction support 2 is vertically arranged on one side of the placement bottom plate 101 and forms an L-shaped structure with the placement bottom plate 101 as a whole. The obliquely braced rod 102 is obliquely arranged, and its two ends are respectively fixedly connected to the same side edges of the placement bottom plate 101 and the reaction support 2 and form an integral body with them. The two obliquely braced rods 102 are arranged at intervals, and the spare tire is placed in the space between the two obliquely braced rods 102. Based on this setting, the width of the placement bottom plate 101 is not less than the thickness of the spare tire. The setting of the obliquely braced rod 102 can not only limit the spare tire to prevent it from falling off, but also play a stiffening role to improve the connection stability and impact resistance between the tire limiting frame 1 and the reaction support 2.

[0033] Furthermore, a first hinge 201 for connecting the fixed end of the telescopic unit 4 is provided on the reaction support 2, and a second hinge 301 for connecting the telescopic end of the telescopic unit 4 is provided on the slewing frame 3.

[0034] In an embodiment of the present application, the telescopic unit 4 is an electric lifting oil cylinder. The fixed end of the electric lifting oil cylinder is rotatably connected to the reaction support 2 through the first hinge 201, and the telescopic end of the electric lifting oil cylinder is rotatably connected to the slewing frame 3 through the second hinge 301. In an embodiment of the present application, both the first hinge 201 and the second hinge 301 are connecting plates provided with a connection hole, and a rotating shaft penetrating the electric telescopic rod is provided in the connection hole.

[0035] Furthermore, the horizontal height of the telescopic end of the telescopic unit 4 is lower than the horizontal height of the fixed end of the telescopic unit 4. Based on this structure, it can conform to the lowering direction of the spare tire, expand the rotation angle of the slewing frame 3, and make it more convenient to lower the spare tire.

[0036] Furthermore, the slewing frame 3 includes two spaced support long rods 302 and a connecting short rod 303 connecting the ends of the two support long rods 302. Combining the above description, one end of the two support long rods 302 is hinged to the end of the placing bottom plate 101 in the tire limiting frame 1 away from the slewing frame 3, and the other end of the support long rod 302 is fixedly connected to the connecting short rod 303 to form an integral body. The slewing frame 3 is integrally in an inverted U shape, so that in the state where the spare tire is retracted, part of the hub of the spare tire can pass through the gap between the two support long rods 302.

[0037] As an alternative embodiment, two connecting plates provided with connection holes are also provided at the end of the placing bottom plate 101 in the tire limiting frame 1 away from the slewing frame 3, and a rotating shaft penetrating the end of the support long rod 302 is provided in the connection hole.

[0038] Furthermore, the first tire connecting belt 5 is arranged on the connecting short rod 303. The first tire connecting belt 5 includes two slings 501 spaced on the connecting short rod 303 and a connecting sling 502 with both ends detachably connected to the two slings 501 respectively. The connecting sling 502 is made of flexible material as a whole. Instead of the traditional stud connection, it can save a lot of time for installing and removing studs. The connecting sling 502 can directly pass through the through hole on the spare tire hub and then connect the two slings 501 at both ends. In an embodiment of the present application, buckles are provided at both ends of the connecting sling 502 to facilitate connecting the two slings 501.

[0039] Further, a second tire connecting band is provided on the tire limiting frame 1 at a position opposite to the first tire connecting band 5. The second tire connecting band is mainly used to cooperate with the tire limiting frame 1 during driving to further fix the spare tire. Specifically, the second tire connecting band includes two connecting ears 6 respectively arranged on both sides of the tire limiting frame 1 and an adjustable binding band 7 with both ends detachably connected to the two connecting ears 6. Through holes are formed in the connecting ears 6. The adjustable binding band 7 is used in the same way as the connecting sling 502 of the first tire connecting band 5, that is, it passes through the through holes on the spare tire hub and is connected to the two connecting ears 6. At the same time, buckles are also arranged at both ends of the adjustable binding band 7 for the through holes on the connecting ears 6. The length of the adjustable binding band 7 can be adjusted to adapt to spare tires of different diameters, and at the same time, the fixing effect of the spare tire can be ensured.

[0040] Figure 3 The figure is a schematic diagram of the deployed state of a spare tire lifting frame provided by an embodiment of the present application. As Figure 3 shown, when a spare tire needs to be replaced, first loosen the second tire connecting band to release the connection between the spare tire and the tire limiting frame 1. Then start the telescopic unit 4. The telescopic unit 4 pushes the rotary frame 3 to drive the spare tire to rotate away from the tire limiting frame 1, so as to gradually lower the spare tire from the vehicle to the ground. After the spare tire touches the ground, the connecting sling 502 in the first tire connecting band 5 becomes slack, and the buckles at both ends are removed from the hanging rings 501 to realize the rapid removal of the spare tire. After the spare tire is replaced, move the replaced old tire under the rotary frame 3, hang the old tire on the rotary frame 3 through the connecting sling 502, then retract the telescopic unit 4, gradually retract the old tire to between the two diagonal braces 102 of the tire limiting frame 1 through the rotary frame 3, and finally fix the old tire with the second tire connecting band.

[0041] The spare tire lifting frame in the present application can limit and fix the spare tire through the tire limiting frame 1 and the first tire connecting band 5, without the need for additional stud connections, reducing the installation and disassembly work. At the same time, the first tire connecting band 5 can also connect the spare tire to the rotary frame 3. When the telescopic unit 4 pushes the rotary frame 3 to rotate, the spare tire can be simultaneously moved to the ground. The overall retracting and deploying process is convenient and fast, without the need to spend a lot of manpower on carrying the spare tire and removing bolts, improving the convenience of the replacement work.
