Description

Technical Field

[0001] This application relates to the field of vehicle technology, and in particular to a spare tire mounting device and a vehicle. Background Technology

[0002] Currently, in the traditional backpack spare tire mounting structure, the spare tire is directly mounted on the rear tailgate.

[0003] In related technologies, the rim of the spare tire is usually open towards the tailgate of the vehicle, and a spare tire cover is installed on the outside of the spare tire for decoration. This makes the center of gravity of the spare tire relatively far away from the tailgate, resulting in the center of gravity of the tailgate with the spare tire installed being shifted to the rear. This makes the operating force required to open or close the tailgate greater, and the mounting structure is prone to deformation due to insufficient strength. Furthermore, the opening of the rim is blocked by the tailgate, making it impossible to utilize the hollow space of the rim. Utility Model Content

[0037] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other.

[0038] The following will refer to the appendix. Figures 1-7 The spare tire mounting device 100 of this application embodiment will be described in detail with reference to the embodiments. The spare tire mounting device 100 is used to mount the spare tire 200 to fix the spare tire 200 to the vehicle. The spare tire mounting device 100 can be mounted on the tailgate 300 of the vehicle, so that the spare tire 200 can be arranged on the tailgate 300 of the vehicle.

[0039] It should be noted that the spare tire 200 has a rim 210, and the spare tire mounting device 100 is used to cooperate and fix it with the rim 210.

[0040] The spare tire mounting device 100 according to an embodiment of this application includes: a mounting bracket 1, a storage box 2, and a connecting component.

[0041] Combination Figure 3 and Figure 5 As shown, the mounting bracket 1 forms a mounting seat 11 that protrudes towards the rim 210. The mounting seat 11 is used to position and cooperate with the rim 210, thereby positioning the spare tire 200 and the mounting seat 11, reducing assembly difficulty. The mounting bracket 1 is provided with a reinforcing part 12, which is connected to the mounting seat 11. The reinforcing part 12 can improve the structural strength of the mounting seat 11 and enhance its resistance to deformation, thus helping to improve the reliability of the connection between the spare tire 200 and the mounting seat 11.

[0042] Reference Figure 7As shown, the storage box 2 has a storage cavity 201, which can be used to store items, thus realizing the storage function. At least part of the storage box 2 is embedded in the rim 210, that is, the storage box 2 can be arranged within the space defined by the rim 210, so that the storage box 2 fits tightly with the spare tire 200, and the internal space of the rim 210 can be used for storage, thereby improving the space utilization rate of the spare tire mounting device 100. At the same time, the storage box 2 can cover the opening of the rim 210, providing a certain degree of protection for the rim 210.

[0043] Combination Figure 3 , Figure 5 and Figure 7 As shown, the connecting assembly can sequentially pass through the mounting base 11, the wheel rim 210 and the storage box 2, and the connecting assembly is used to fix the spare tire 200 between the mounting bracket 1 and the storage box 2, and the opening of the wheel rim 210 is arranged facing away from the mounting bracket 1.

[0044] Combination Figure 1 and Figure 3 As shown, the mounting bracket 1 is used to mount and cooperate with the tailgate 300 of the vehicle, so that the spare tire mounting device 100 can be arranged on the tailgate 300 of the vehicle, and the spare tire 200 can be mounted on the outside of the tailgate 300 of the vehicle through the spare tire mounting device 100.

[0045] When the spare tire 200 is mounted on the tailgate 300 via the spare tire mounting device 100, the opening of the rim 210 is positioned facing away from the tailgate. This places the center of gravity of the spare tire 200 closer to the tailgate 300, reducing the lever arm of the tailgate 300 when opening or closing, and lowering the driving force required to open or close the tailgate 300. This facilitates the opening or closing of the spare tire 200 by the tailgate 300. In other words, when the opening of the rim 210 is open towards the rear of the vehicle, the center of gravity of the spare tire 200 can be positioned closer to the tailgate 300.

[0046] It should be noted that in the relevant technologies, in the traditional spare tire mounting structure, the spare tire is directly mounted to the tailgate, with the rim of the spare tire open towards the tailgate side, and a spare tire cover is installed on the outside of the spare tire for decoration. This places the center of gravity of the spare tire relatively far from the tailgate, resulting in a rearward shift of the tailgate's center of gravity. This makes the tailgate require greater operating force to open or close, and the mounting structure is prone to deformation due to insufficient strength. Furthermore, the opening in the rim is blocked by the tailgate, preventing the utilization of the hollow space in the rim.

[0047] According to the embodiment of this application, the spare tire mounting device 100 installs and fixes the spare tire 200 by connecting and cooperating with the storage box 2 through the mounting bracket 1. The rim 210 of the spare tire 200 is open away from the mounting bracket 1, thereby shifting the center of gravity of the spare tire 200 towards the mounting bracket 1. This helps reduce the drive arm at the tailgate 300. Furthermore, the reinforcing part 12 enhances the structural strength of the mounting base 11, thereby increasing the load-bearing capacity of the mounting bracket 1 and reducing the risk of damage to the mounting bracket 1 due to insufficient strength. Simultaneously, the storage box 2 is located within the open space of the rim 210 and is used for storage, thus utilizing the hollow space of the rim 210 and improving the space utilization rate of the spare tire 200.

[0048] In some examples of this application, the connecting assembly includes a first connector 31 and a second connector 32. The first connector 31 can sequentially pass through the mounting base 11, the wheel rim 210, and the storage box 2 from the side of the mounting bracket 1 away from the wheel rim 210. The second connector 32 is disposed in the storage cavity 201 and is used to connect and cooperate with the first connector 31 to fix the spare tire 200 between the mounting bracket 1 and the storage box 2. Furthermore, the second connector 32 can hold the spare tire 200 with the opening of the wheel rim 210 facing away from the mounting bracket 1. The first connector 31 is constructed as a bolt, and the second connector 32 is constructed as a nut.

[0049] Combination Figure 3 and Figure 5 As shown, in some embodiments of this application, the mounting base 11 is provided with a plurality of positioning bosses 111, which are used for insertion and positioning with the rim 210, and a first through hole 112 for the connecting component to pass through is provided on the positioning bosses 111, and the plurality of positioning bosses 111 are arranged circumferentially on the mounting base 11.

[0050] The wheel rim 210 has a positioning structure, such as a hole structure or a groove structure, for inserting a positioning boss 111. It is understood that bolt holes are typically provided on the wheel rim 210, through which the spare tire 200 can be connected and fixed to the axle. When the spare tire 200 needs to be mounted on the spare tire mounting device 100, the bolt holes can be engaged with the positioning boss 111 to position the wheel rim 210 and the mounting bracket 1.

[0051] Reference Figure 5 As shown, the mounting bracket 1 is provided with multiple positioning bosses 111, and each positioning boss 111 is provided with a set of connecting components. In other words, the mounting bracket 1, storage box 2 and spare tire 200 can be connected and cooperated through multiple sets of connecting components, thereby improving the assembly reliability of spare tire 200 at spare tire mounting device 100.

[0052] like Figure 5As shown in a specific embodiment of this application, the mounting base 11 is provided with three positioning bosses 111. The three positioning bosses 111 are arranged in a non-collinear three-point arrangement on the mounting base 11, that is, the three positioning bosses 111 are located at the three vertices of the mounting base 11, so that the mounting base 11 and the wheel rim 210 can achieve three-point positioning, thereby improving the positioning accuracy between the mounting base 11 and the wheel rim 210.

[0053] It should be noted that the number and arrangement of the positioning bosses 111 on the mounting base 11 can be adapted to the structure of the rim 210, including but not limited to three or four.

[0054] Reference Figure 6 The mounting base 11 is raised to one side on the mounting bracket 1. A hollow structure is formed in the opposite direction of the raised mounting base 11. The hollow structure allows bolts in the connecting components to be inserted, which facilitates and keeps some bolts protruding from the first through hole 112 to form a pre-installation structure at the mounting base 11. This helps to reduce the assembly difficulty of the spare tire 200 and the spare tire mounting device 100, and can reduce the weight of the mounting bracket 1 while ensuring the structural strength at the mounting base 11, thus achieving a lightweight design of the spare tire mounting device 100.

[0055] Combination Figure 3 and Figure 5 As shown, in some embodiments of this application, the reinforcing part 12 includes a first reinforcing rib 121. The first reinforcing rib 121 is disposed on the side surface of the mounting bracket 1 facing the rim 210, and the first reinforcing rib 121 is connected to the outer peripheral wall of the mounting base 11. Thus, the structural strength of the mounting base 11 can be improved by the first reinforcing rib 121, which helps to improve the load-bearing capacity of the mounting bracket 1 at the mounting base 11.

[0056] Reference Figure 5 As shown, the first reinforcing rib 121 extends from the surface of the mounting bracket 1 opposite to the rim 210 to the outer peripheral wall of the mounting base 11, thereby improving the deformation resistance of the mounting base 11. At the same time, multiple first reinforcing ribs 121 can be provided on the mounting bracket 1, and the multiple first reinforcing ribs 121 are arranged at intervals along the circumferential direction of the mounting base 11, thereby fully improving the structural strength of the mounting base 11.

[0057] like Figure 5 As shown, in some embodiments of this application, the reinforcing part 12 includes a second reinforcing rib 122. The second reinforcing rib 122 is disposed on the side surface of the mounting base 11 facing the rim 210, and the second reinforcing rib 122 is connected to the outer peripheral wall of the positioning boss 111. The second reinforcing rib 122 enhances the structural strength of the positioning boss 111, which helps to improve the deformation resistance of the positioning boss 111 and improve the reliability of the fit between the positioning boss 111 and the rim 210.

[0058] Reference Figure 5 As shown, the second reinforcing rib 122 is disposed on the side surface of the mounting base 11 facing the rim 210 and extends to the positioning boss 111 to improve the deformation resistance of the positioning boss 111. The first reinforcing rib 121 in the mounting bracket 1 can also extend to the outer peripheral wall of the positioning boss 111.

[0059] It should be noted that the mounting bracket 1 can be provided with both a first reinforcing rib 121 and a second reinforcing rib 122 to fully enhance the structural strength of the mounting bracket 1 at the mounting seat 11, which helps to improve the load-bearing capacity of the mounting seat 11 and improve the reliability of the fit between the mounting bracket 1 and the wheel rim 210.

[0060] Combination Figure 5 and Figure 6 As shown, in some embodiments of this application, the mounting bracket 1 is provided with a connecting part 131, which is used to connect and cooperate with the tailgate 300 of the vehicle, thereby assembling and fixing the mounting bracket 1 on the tailgate 300.

[0061] The connecting part 131 is constructed as a connecting hole, through which a bolt can pass. The bolt can be threaded into the threaded structure (such as a nut or a threaded hole) at the back door 300 to realize the installation and engagement of the mounting bracket 1 and the back door 300.

[0062] Combination Figure 3 and Figure 5 As shown, the mounting bracket 1 has an annular boss 132 at the connecting part 131. The annular boss 132 is raised from the mounting bracket 1 toward the rim 210 side and surrounds the connecting part 131 in the circumferential direction. The annular boss 132 enhances the structural strength of the connecting part 131 and improves the connection reliability between the mounting bracket 1 and the back door 300.

[0063] In some embodiments of this application, the mounting bracket 1 is provided with a plurality of connecting parts 131, and the plurality of connecting parts 131 are arranged at intervals along the circumferential direction of the mounting bracket 1, so that the mounting bracket 1 and the back door 300 can be connected at multiple points, which helps to improve the reliability of the connection between the mounting bracket 1 and the back door 300.

[0064] Combination Figure 5 and Figure 6 As shown in a specific embodiment of this application, the mounting bracket 1 is provided with four connecting parts 131. The four connecting parts 131 are respectively located near the four top corners of the mounting bracket 1, which can increase the cooperation range between the mounting bracket 1 and the back door 300 and help improve the connection effect between the mounting bracket 1 and the back door 300.

[0065] like Figure 6 As shown, in some embodiments of this application, an annular washer is provided on the surface of the mounting bracket 1 opposite to the tailgate 300. The annular washer can be clamped between the mounting bracket 1 and the tailgate 300 when the mounting bracket 1 and the tailgate 300 are connected and engaged.

[0066] Combination Figure 2 , Figure 4 and Figure 7 As shown, in some embodiments of this application, the storage box 2 includes a box body 21 and a cover 22. The box body 21 has a receiving groove that opens to the side away from the mounting bracket 1. The cover 22 is disposed at the open end of the box body 21 and is used to cover the receiving groove to form a closed storage cavity 201.

[0067] Understandably, the box body 21 can be used to store items, and the lid 22 can be arranged at the open end of the receiving slot to close the open end of the box body 21, preventing items placed in the receiving slot from being exposed. When it is necessary to place items into the storage cavity 201, the lid 22 is driven to move to open the box body 21, and the user can take or put items from the open side of the box body 21 (which is also the side of the spare tire 200 away from the back door 300).

[0068] Combination Figure 4 and Figure 7 As shown in a further embodiment of this application, the box body 21 includes a bottom wall 211 and a peripheral wall 212. The bottom wall 211 and the rim 210 are disposed opposite each other in the axial direction of the spare tire 200. The bottom wall 211 is arranged in the hollow space formed by the rim 210. The peripheral wall 212 extends from the outer periphery of the bottom wall 211 toward the side away from the mounting bracket 1. The peripheral wall 212 and the bottom wall 211 define the above-mentioned receiving groove. Moreover, the outer peripheral surface of the peripheral wall 212 is provided with a buffer member 23. The buffer member 23 can be sandwiched between the peripheral wall 212 and the inner wall surface of the rim 210. Thus, the vibration between the box body 21 and the rim 210 can be buffered by the buffer member 23, avoiding abnormal noise caused by the contact between the storage box 2 and the rim 210. This achieves buffering and noise reduction between the box body 21 and the rim 210, which helps to improve the NVH (Noise, Vibration, Harshness) performance of the whole vehicle.

[0069] In some embodiments of this application, the buffer 23 can be constructed as a sponge block, and the sponge block is fixed to the peripheral wall 212 by adhesive. When the box body 21 is connected and engaged with the rim 210, the sponge block can be arranged between the circumferential direction of the box body 21 and the rim 210. It should be noted that the buffer 23 can also be constructed as a rubber block with a cushioning function, etc.

[0070] Reference Figure 4As shown, multiple buffers 23 are provided on the box body 21. The multiple buffers 23 are arranged at intervals in the circumferential direction of the box body 21, so that the impact between the box body 21 and the wheel rim 210 in multiple directions can be buffered by the buffers 23.

[0071] It is understood that the box body 21 is arranged inside the rim 210, and the peripheral wall 212 of the box body 21 is opposite to the part of the rim 210 used to mate with the outer tire. The box body 21 can support and mate with the rim 210 in the circumferential direction, so as to position the rim 210 through the box body 21, and further improve the reliability of the mating between the rim 210 and the storage box 2.

[0072] Combination Figure 4 and Figure 7 As shown, the bottom wall 211 is provided with a recess 2111 that is recessed toward the side away from the mounting bracket 1. The recess 2111 is adapted to avoid part of the rim 210 in the axial direction of the spare tire 200, so that the box body 21 is constructed to fit the shape of the rim 210 and can make full use of the space inside the rim 210 to improve the storage capacity of the storage box 2.

[0073] like Figure 4 As shown, in some embodiments of this application, the bottom wall 211 is provided with a second through hole 2112, which is used for the connecting component to pass through in order to form a connecting structure on the storage box 2.

[0074] In some embodiments of this application, the connecting assembly may include a first connector 31 configured as a bolt and a second connector 32 configured as a nut. During the assembly of the mounting bracket 1, the rim 210, and the storage box 2, the first connector 31 may be sequentially passed through the bottom wall 211 of the mounting bracket 1, the rim 210, and the box body 21 and extended into the receiving groove. The second connector 32 may be arranged in the receiving groove and threadedly engaged with the portion of the first connector 31 that extends into the receiving groove, so as to lock and position the mounting bracket 1, the rim 210, and the box body 21 in the axial direction, thereby realizing the installation and fixation of the spare tire mounting device 100 and the spare tire 200.

[0075] like Figure 1 As shown, in some embodiments of this application, the box body 21 further includes a rotating shaft 41 and a bushing 42. The rotating shaft 41 is disposed on one of the box body 21 and the cover 22, and the bushing 42 is disposed on the other of the box body 21 and the cover 22. The bushing 42 is sleeved and fitted with the rotating shaft 41, so that the cover 22 is rotatably mounted on the box body 21 around the rotating shaft 41.

[0076] When the rotating shaft 41 is mounted on the box body 21, the bushing 42 is mounted on the lid 22; when the rotating shaft 41 is mounted on the lid 22, the bushing 42 is mounted on the box body 21. Thus, the box body 21 and the lid 22 can be rotatably connected via the rotating shaft 41 and the bushing 42, allowing the lid 22 to rotate relative to the box body 21 around the rotating shaft 41, thereby achieving the opening or closing action of the lid 22 relative to the box body 21.

[0077] In some embodiments of this application, the rotating shaft 41 is arranged vertically, that is, the axial direction of the rotating shaft 41 is parallel to the vertical direction, so that the lateral flipping action of the cover 22 can be realized, and the flipping action of the cover 22 is simple and easy to operate.

[0078] like Figure 1 and Figure 7 As shown, in some embodiments of this application, the storage box 2 is provided with a locking assembly 5, which is used to lock the cover to the box body 21, thereby improving the storage security of the storage box 2. It is understood that the locking assembly 5 includes two parts respectively disposed on the cover 22 and the box body 21, and the two parts can lock together to selectively lock the cover 22 to the box body 21.

[0079] In some embodiments of this application, the mounting bracket 1 is constructed as a cast aluminum part, thereby achieving a lightweight design while improving the structural strength of the mounting bracket 1.

[0080] Understandably, cast aluminum parts are lightweight and high-strength, which can meet the structural strength requirements of mounting bracket 1 while reducing weight. In addition, cast aluminum parts have good corrosion resistance, which can extend the service life of mounting bracket 1.

[0081] Reference Figures 1-7 The process of installing a spare tire 200 using the spare tire mounting device 100 according to an embodiment of this application is described as follows:

[0082] First, the first connector 31 can be inserted through the first through hole 112 and the first connector 31 can be preset at the mounting base 11. Then, the mounting bracket 1 can be installed and cooperated with the back door 300 through the connecting part 131 to fix the mounting bracket 1 on the back door 300.

[0083] Secondly, the spare tire 200 is positioned to mate with the mounting base 11 so that the mounting bracket 1 is positioned and mated with the rim 210, and the first connecting piece 31 can pass through the hole structure reserved on the rim 210.

[0084] Furthermore, the storage box 2 in the open state is arranged correspondingly to the wheel rim 210, so that the first connecting piece 31 can be inserted into the receiving groove through the second through hole 2112, and the second connecting piece 32 in the receiving groove is connected and cooperated with the first connecting piece 31 to connect and fix the mounting bracket 1, the spare tire 200 and the storage box 2. Finally, the cover 22 is placed on the box body 21.

[0085] Thus, the spare tire 200 is installed and fixed on the tailgate 300 by the spare tire mounting device 100, and the cover 22 of the storage box 2 is exposed from the opening of the wheel rim 210. The user can selectively open the cover 22 to store and retrieve items according to the storage needs.

[0086] The spare tire mounting device 100 according to the embodiments of this application has at least the following advantages over the prior art:

[0087] (1) The mounting bracket 1 is made of cast aluminum. A reinforcing structure is provided at the mounting position of the mounting bracket 1 (e.g., mounting base 11, connecting part 131), so that the mounting bracket 1 has high structural strength and can achieve lightweight.
