Description

Technical Field

[0001] The present application relates to the field of vehicle technology, in particular to a spare tire rack for an automobile. Background Art

[0002] For some cars, the spare tire is an indispensable part of the car, and the placement of the spare tire is also particularly important, so that the tire can be replaced in time when an accident such as a tire blowout occurs, so the spare tire rack has also been widely used. Traditional spare tire racks are designed according to the model of the car, and generally use the corresponding spare tire rack to place the spare tire. It is impossible to fix spare tires of different models and sizes, and the versatility is poor.

[0003] In the related art, the luggage box rack generally uses multiple clamps to fix the spare tire, which can be suitable for spare tires of different sizes within a certain range. However, the clamp parts are often complex in structure, inconvenient to operate and high in cost, which is not conducive to the removal of the spare tire. Utility Model Content

[0004] Based on this, it is necessary to provide a spare tire rack for automobiles with a simple structure and convenient operation, so as to improve the efficiency of disassembling and assembling the spare tire and reduce the production cost.

[0005] In order to solve the above technical problems, this application provides the following technical solutions:

[0006] A spare tire rack for an automobile comprises a spare tire plate and a plurality of clamping mechanisms, wherein the spare tire plate is used to be installed on the body of an automobile and carry a spare tire; the plurality of clamping mechanisms are installed on the spare tire plate and are arranged at intervals along the circumference of the spare tire plate to enclose and form a clamping gap for clamping the spare tire; each clamping mechanism comprises a threaded rod and a clamping plate, wherein a guide groove is provided on the spare tire plate, one end of the threaded rod is passed through the side of the spare tire plate to the guide groove and is rotatably connected to the spare tire plate, and the other end is located outside the guide groove and forms an operating portion; one end of the clamping plate extends into the guide groove along a first direction and is threadably connected to the threaded rod; wherein the first direction is arranged at an angle to the axial direction of the threaded rod; and the threaded rod is rotated by the operating portion so that the clamping plate moves in the guide groove along the axis of the threaded rod to adjust the size of the clamping gap.

[0007] In one of the embodiments, a toggle block is provided at the operating portion, and the toggle block is fixedly connected to the threaded rod.

[0008] It is understandable that by fixedly connecting the toggle block to the threaded rod and then rotating the threaded rod via the toggle block, the rotation of the threaded rod can be made more labor-saving and easy to operate.

[0009] In one embodiment, the guide groove is configured as a rectangular groove, the portion of the clamping plate extending into the guide groove forms a guide block, the guide block is sleeved on the threaded rod and configured as a rectangular block, and the side surface of the guide block is in contact with the wall surface of the guide groove.

[0010] It can be understood that both the guide groove and the guide block are configured as rectangular grooves, and the side surfaces of the guide block are in contact with the wall surfaces of the guide groove, so that the guide block will not be dislocated or rotated during movement, thereby making the guide block more stable when moving in the guide groove; and, the guide block is sleeved on the threaded rod, so that the threaded rod directly drives the guide block to slide in the guide groove during movement, thereby realizing the movement of the clamping plate; in addition, the guide block is formed by the portion of the guide plate extending into the guide groove, that is, the two are an integrated structure, so the structure is more stable.

[0011] In one of the embodiments, the clamping mechanism further includes a limiting unit, which is installed on the spare tire plate and connected to the clamping plate.

[0012] It can be understood that the limiting unit plays an auxiliary role in the clamping of the clamping plate, so that the clamping of the spare tire by the clamping plate is more stable.

[0013] In one of the embodiments, the limiting unit includes a limiting plate and a limiting rod. The limiting plate is fixed to the spare tire plate. A limiting hole is provided on the limiting plate. One end of the limiting rod is fixedly connected to the clamping plate, and the other end is passed through the limiting hole. Moreover, the axis of the limiting rod is arranged parallel to the axis of the threaded rod.

[0014] It can be understood that the limiting hole on the limiting plate plays a limiting and guiding role for the limiting rod. Through the setting of the limiting plate and the limiting rod, one end of the limiting rod is fixedly connected to the clamping plate, so that the clamping plate can always move along the axis of the limiting rod when moving, thereby making the movement of the clamping plate more stable.

[0015] In one embodiment, the limiting unit further includes an elastic member, which is sleeved on the limiting rod and arranged between the limiting plate and the clamping plate in a pre-compressed manner, and two ends of the elastic member respectively abut against the limiting plate and the clamping plate.

[0016] It can be understood that the two ends of the elastic member are respectively against the limit plate and the clamping plate, and are always in a pre-compressed state, so the clamping plate is always subjected to the elastic force from the elastic member, which plays an auxiliary role in supporting the clamping plate, and further provides the clamping force of the clamping plate on the spare tire, making the fixation of the spare tire more stable and reliable; at the same time, it also reduces the extrusion force on the thread between the threaded rod and the guide block, reducing the risk of thread damage.

[0017] In one embodiment, the number of the clamping mechanisms is configured to be four, and the four clamping mechanisms are arranged on the spare tire plate in a rectangular array.

[0018] It can be understood that the four supporting mechanisms are arranged in a rectangular array on the spare tire plate, which can clamp and fix the spare tire from multiple directions, so that the spare tire is evenly stressed and thus stably fixed on the spare tire plate.

[0019] In one embodiment, the automobile spare tire rack further includes a positioning rod and a locking member. The positioning rod is fixed to the spare tire plate and is disposed in the middle of the clamping gap for the spare tire to pass through. The locking member and the positioning rod are detachably connected.

[0020] It can be understood that by setting the positioning rod, the spare tire can be placed on the spare tire board so that it will not shake on the spare tire board, and then connected to the positioning rod by a locking piece, the spare tire can be fixed in the direction along the positioning rod.

[0021] In one embodiment, the locking member and the positioning rod are configured to be threadedly connected.

[0022] It can be understood that, by utilizing the threaded connection between the locking member and the positioning rod, the connection between the locking member and the positioning rod can be achieved by simply rotating the locking member, which is convenient and quick.

[0023] Compared with the prior art, the spare tire rack of the automobile is provided with a threaded rod and a clamping plate, so that when the spare tire is installed on the spare tire rack of the automobile, the clamping plate can be moved in the guide groove along the axis direction of the threaded rod only by rotating the threaded rod, so as to clamp and fix the spare tire. This structure is not only simple, but also easy to operate and low in cost. At the same time, the threaded rod is rotatably connected to the spare tire plate, so that the rotation of the threaded rod can be stopped and fixed at any time, that is, the fixing of the clamping plate can be completed only by rotating the threaded rod, which is conducive to improving the efficiency of disassembling and installing the spare tire.

[0036] like Figure 1 As shown, the present application provides a spare tire rack 100 for an automobile. The spare tire rack 100 for an automobile is mainly used for assembling spare tires of different sizes so that the spare tire can be replaced promptly and effectively in the event of an unexpected situation such as a tire blowout, thereby improving the travel efficiency of the automobile.

[0037] Specifically, combined Figures 2 to 4 The spare tire rack 100 of an automobile comprises a spare tire plate 10 and a plurality of clamping mechanisms 20. The spare tire plate 10 is used to be installed on the body of an automobile and to carry the spare tire 200. The plurality of clamping mechanisms 20 are installed on the spare tire plate 10 and are arranged at intervals along the circumference of the spare tire plate 10 to enclose and form a clamping gap 101 for clamping the spare tire 200. Each clamping mechanism 20 comprises a threaded rod 21 and a clamping plate 22. A guide groove 11 is provided on the spare tire plate 10. One end of the threaded rod 21 extends from the side of the spare tire plate 10. It is inserted into the guide groove 11 and is rotatably connected to the spare tire plate 10, and the other end is located outside the guide groove 11 and forms an operating portion 211; one end of the clamping plate 22 extends into the guide groove 11 along a first direction and is threadedly connected to the threaded rod 21; wherein the first direction is set at an angle with the axial direction of the threaded rod 21; and, by rotating the threaded rod 21 through the operating portion 211, the clamping plate 22 moves along the axis of the threaded rod 21 in the guide groove 11 to adjust the size of the clamping gap 101. In this way, by setting the threaded rod 21 and the clamping plate 22, in the process of installing the spare tire 200 on the spare tire rack 100 of the automobile, the clamping plate 22 can be moved in the guide groove 11 along the axial direction of the threaded rod 21 by simply rotating the threaded rod 21, thereby achieving the clamping and fixing of the spare tire 200. This structure is not only simple, but also easy to operate and low in cost. At the same time, the threaded rod 21 is rotatably connected to the spare tire plate 10 so that the rotation of the threaded rod 21 can be stopped and fixed at any time, that is, the fixing of the clamping plate 22 can be completed only by rotating the threaded rod 21, which is beneficial to improving the disassembly and assembly efficiency of the spare tire 200.

[0038] like Figure 1 , Figure 2 and Figure 3 As shown, the spare tire plate 10 is roughly circular, and its shape is adapted to the tire shape of the automobile. Of course, it is not limited thereto, and the shape of the spare tire plate 10 can also be adjusted accordingly according to the installation position on the automobile, for example, it can be set to a square shape, etc.

[0039] Furthermore, a mounting arm 12 is provided at the edge of the spare tire plate 10 , and a mounting hole 121 is opened on the mounting arm 12 . Fasteners such as bolts and buckles are passed through the mounting hole 121 to fix the spare tire plate 10 on the car.

[0040] Specifically, there are at least three mounting arms 12, which are arranged at intervals along the circumference of the spare tire plate 10, thereby providing more mounting points for the spare tire plate 10 and improving the stability of the installation of the spare tire plate 10. Here, the number of mounting arms 12 is configured to be three, four or five.

[0041] In one embodiment, the number of the clamping mechanisms 20 is set to four, and the four clamping mechanisms 20 are arranged in a rectangular array on the spare tire plate 10. In this way, the clamping forces from all directions on the spare tire 200 can be as balanced as possible, making the clamping effect more stable; of course, it is not limited to this, and the number of the clamping mechanisms 20 can also be set to three or five, which can be set according to actual needs.

[0042] Specifically, the clamping mechanism 20 includes a threaded rod 21 and a clamping plate 22. The guide groove 11 is opened on the spare tire plate 10 and is arranged as a rectangular groove. One end of the threaded rod 21 passes through the side of the spare tire plate 10 to the guide groove 11, and the other end is located outside the guide groove 11; one end of the clamping plate 22 extends into the guide groove 11 and is threadedly connected to the threaded rod 21.

[0043] Furthermore, one end of the threaded rod 21 is passed through the side of the spare tire plate 10 to the guide groove 11 and is rotatably connected to the spare tire plate 10; a toggle block 212 is provided at the other end of the threaded rod 21 outside the guide groove 11, and the toggle block 212 and the threaded rod 21 together constitute an operating part 211, and the toggle block 212 and the threaded rod 21 are fixedly connected; through the setting of the operating part 211, the threaded rod 21 can be rotated by operating the toggle block 212, and the movement of the threaded rod 21 in the guide groove 11 can be realized through the rotational connection between the threaded rod 21 and the spare tire plate 10.

[0044] Furthermore, the portion of the clamping plate 22 extending into the guide groove 11 forms a guide block 221, which is sleeved on the threaded rod 21 and is configured as a rectangular block, and the side surface of the guide block 221 is in contact with the wall surface of the guide groove 11; in this way, the guide block 221 can move stably in the guide groove 11.

[0045] In this embodiment, one end of the clamping plate 22 is connected to the limiting rod 232, and the other end is provided with an anti-skid pad (not shown) for the purpose of better clamping and fixing the spare tire 200 so that the spare tire 200 will not rotate around the positioning rod 30. Of course, the other end of the clamping plate 22 can also be provided with a rough surface or other structure to increase the friction between the clamping plate 22 and the spare tire 200, which can also better fix the spare tire 200.

[0046] like Figures 1 to 4 As shown, the clamping mechanism 20 also includes a limiting unit 23, which is installed on the spare tire plate 10 and connected to the clamping plate 22. In this way, the limiting unit 23 plays an auxiliary role in clamping the clamping plate 22, so that the clamping plate 22 clamps the spare tire more stably.

[0047] Specifically, the limiting unit 23 includes a limiting plate 231 and a limiting rod 232. The limiting plate 231 is fixed on the spare tire plate 10. A limiting hole 2311 is provided on the limiting plate 231. One end of the limiting rod 232 is fixedly connected to the clamping plate 22, and the other end is inserted into the limiting hole 2311. Moreover, the axis of the limiting rod 232 is arranged parallel to the axis of the threaded rod 21. When the clamping plate 22 moves, the limiting rod 232 can be driven to shuttle in the limiting hole 2311, and the moving direction of the limiting rod 232 is always consistent with the direction of the limiting hole 2311. In this way, the movement of the clamping plate 22 can be more stable.

[0048] Preferably, the limiting plate 231 is configured to be rectangular and is vertically fixed to the spare tire plate 10 ; the limiting hole 2311 is provided in the middle of the limiting plate 231 , and the direction of the limiting hole 2311 is the direction in which the positioning rod 30 is located.

[0049] like Figure 4 As shown, the limiting unit 23 also includes an elastic member 233, which is sleeved on the limiting rod 232, and the elastic member 233 is arranged between the limiting plate 231 and the clamping plate 22 in a pre-compressed manner, and the two ends of the elastic member 233 are respectively against the limiting plate 231 and the clamping plate 22. In this way, the elastic member 233 can always be limited by the limiting rod 232, and the direction of the elastic force generated is always consistent with the axial direction of the limiting rod 232; in this way, the elastic member 233 can always give an elastic force to the clamping plate 22, making the clamping effect of the clamping plate 22 more stable, and at the same time, it also reduces the extrusion force on the thread between the threaded rod 21 and the guide block 221, reducing the risk of thread damage.

[0050] like Figure 1As shown, the spare tire rack 100 of the automobile further includes a positioning rod 30 and a locking member 40. The positioning rod 30 is fixed on the spare tire plate 10 and is arranged in the middle of the clamping gap 101 for the spare tire 200 to pass through. The locking member 40 is arranged at one end of the positioning rod 30 away from the spare tire plate 10. The locking member 40 and the positioning rod 30 are detachably connected. In this way, the spare tire can be placed on the spare tire plate 10 so that it will not shake on the spare tire plate 10. Then, the locking member 40 is connected to the positioning rod 30 so that the spare tire can be fixed and limited in the direction along the positioning rod 30. In addition, the detachable manner can facilitate the disassembly and assembly of the locking member 40, thereby facilitating the removal and placement of the spare tire.

[0051] In this embodiment, the positioning rod 30 is installed in the middle of the spare tire plate 10 and passes through the spare tire 200, and the connection between the positioning rod 30 and the locking member 40 is a threaded connection. That is, after the spare tire 200 is placed on the spare tire plate 10 through the positioning rod 30, the locking member 40 and the positioning rod 30 are threadedly connected to limit the position of the spare tire 200 and fix it on the spare tire plate. Of course, it is not limited to this, and the locking member 40 can also be configured as a pin shaft. In this case, a limiting hole can be opened on the positioning rod 30, and then the pin shaft is inserted into the limiting hole, which can also be achieved.

[0052] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0053] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the scope of patent protection of the present application shall be subject to the attached claims.
