This method not only results in a large number of welds, but also in stress concentration at the weld locations. Therefore, frequent bumps and vibrations during vehicle driving can easily lead to weld cracking, thereby affecting the reliability of the spare tire's fixation. Utility Model Content

DETAILED DESCRIPTION
[0021] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.
[0022] It should be noted that when an element is referred to as being "disposed on" another element, it may be directly on the other element or indirectly on the other element. It should be understood that the terms "upper", "lower", "front", "back", "top", "bottom", "inside", "outside", etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on this application. In the description of this application, "plurality" means two or more, unless otherwise clearly and specifically defined.
[0023] Please also refer to Figure 1 and Figure 2 The spare tire mounting base provided by the present invention will now be described. The spare tire mounting base comprises an integrally formed mounting base body having a connecting surface 10 and a limiting surface 20 spaced apart from each other. The connecting surface 10 is connected to the vehicle body mounting position, and the limiting surface 20 abuts against the spare tire hub 60. The limiting surface 20 has a fastener 40 adapted to secure the spare tire hub 60. A support wall 30 is formed on the mounting base body between the connecting surface 10 and the limiting surface 20. Reinforcement ribs 31 are arranged on the inner and / or outer sidewalls of the support wall 30.
[0024] First of all, it should be understood that in this embodiment, the vehicle body mounting position can specifically be a partial area of the rear door of the vehicle body, or it can be a mounting position on a fixed or flip-up bracket installed on the rear part of the vehicle body; the fixing method between the connecting surface 10 and the vehicle body mounting position can be a hard connection method using direct welding, or it can be a detachable connection method using screw fixation.
[0025] It should be noted that, in this embodiment, the mounting seat body can specifically be an integral die-cast aluminum alloy component; the connecting surface 10 and the limiting surface 20 are spaced apart from each other, and a supporting wall 30 is formed between the connecting surface 10 and the limiting surface 20. The supporting wall 30 can be understood here as a straight cylinder or a conical cylinder structure, and the connecting surface 10 and the limiting surface 20 are connected as one through the supporting wall 30. The supporting wall 30 can be formed into a hollow shell structure with at least one end open based on the connecting surface 10 and the limiting surface 20. On this basis, the mounting seat body can also have a connecting structure for installing a camera and a spare tire cover. That is to say, the one-piece mounting seat body integrates all the connecting structures required for the spare tire mounting seat. Compared with the multi-part assembly welding method, on the one hand, the welds are eliminated, thereby avoiding the problem of weld cracking and facilitating weight reduction. On the other hand, the integration of the overall structure is improved, which is more conducive to improving the structural strength.
[0026] It should be explained that the parts where the connecting surface 10 and the supporting wall 30 are connected, and the parts where the limiting surface 20 and the supporting wall 30 are connected in this embodiment are both bending transition areas. These areas are prone to stress concentration and affect the overall structural stability of the mounting seat body. Therefore, reinforcing support ribs 31 are arranged on the inner wall surface and / or outer wall surface of the supporting wall 30, and the reinforcing support ribs 31 are used to disperse and transfer the concentrated stress, thereby avoiding deformation or fracture of the mounting seat body due to force; specifically, in this embodiment, each reinforcing support rib 31 can extend from the connecting surface 10 toward the limiting surface 20, or can extend from the limiting surface 20 toward the connecting surface 10. Of course, the reinforcing support rib 31 can also be connected to the connecting surface 10 and the limiting surface 20 at both ends, thereby improving the structural reinforcement effect.
[0027] Compared with the prior art, the spare tire mounting seat provided in this embodiment has a supporting wall 30 formed between the connecting surface 10 and the limiting surface 20 spaced apart from each other on the integrally formed mounting seat body, so that the mounting seat body forms a hollow shell component, which not only has high structural integrity but also is conducive to lightweight structure; the connecting surface 10 is fixed to the vehicle body mounting position, the limiting surface 20 is abutted against the spare tire hub 60 and the spare tire hub 60 is fixed by the fastener 40 to achieve reliable installation of the spare tire, which can eliminate the connecting welds between components and avoid stress concentration and fracture at the weld position, thereby improving the structural strength of the mounting seat body and facilitating weight reduction; in addition, by arranging reinforcing support ribs 31 on the inner wall surface and / or outer wall surface of the supporting wall 30, the structural strength of the mounting seat body can be further improved, the risk of stress fracture can be reduced, and the reliability of spare tire installation can be improved.
[0028] In some embodiments, see Figure 1 and Figure 2 The limiting surface 20 closes one end of the supporting wall 30, and the connecting surface 10 is bent toward the periphery of the other end of the supporting wall 30; wherein, the reinforcing support ribs 31 arranged on the inner wall surface of the supporting wall 30 are connected to the limiting surface 20, and the reinforcing support ribs 31 arranged on the outer wall surface of the supporting wall 30 are connected to the connecting surface 10.
[0029] The limiting surface 20 is closed and connected to one end of the supporting wall 30, and the connecting surface 10 is equivalent to being connected to the outer periphery of the other end of the supporting wall 30. In this way, a negative angle structure is formed between the inner wall surface of the supporting wall 30 and the limiting surface 20, and between the outer wall surface of the supporting wall 30 and the connecting surface 10. The reinforcing support ribs 31 located on the inner wall surface of the supporting wall 30 can be connected to the limiting surface 20 and the supporting wall 30 at the same time, thereby improving the connection strength between the limiting surface 20 and the supporting wall 30. Similarly, the reinforcing support ribs 31 located on the outer wall surface of the supporting wall 30 can be connected to the connecting surface 10, thereby improving the connection strength between the connecting surface 10 and the supporting wall 30.
[0030] Specifically, the reinforcing support ribs 31 may be triangular ribs. Using triangular ribs not only improves structural stability but also matches the internal angle structure, thereby reducing molding difficulty.
[0031] Please note that Figure 1 The two opposite side walls of the supporting wall 30 have avoidance grooves 32, and the notches of the avoidance grooves 32 face the connecting surface 10; the supporting wall 30 is bent outward at the boundary of the avoidance groove 32 to form a folded edge 33, and the folded edge 33 is connected to the connecting surface 10.
[0032] Since there may be ribs, beams or other components on the vehicle body mounting position, in order to avoid these components, an avoidance groove 32 is set on the supporting wall 30, so that the mounting seat body is connected astride these components, thereby improving the connection flexibility and adaptability between the mounting seat body and the vehicle body mounting position; on this basis, by setting a folded edge 33 along the boundary of the avoidance groove 32, and connecting the folded edge 33 with the connecting surface 10 that is also bent toward the outside of the supporting wall 30, the overall structural strength can be improved, and the mounting seat body can be prevented from being deformed by force and affecting the spare tire installation stability.
[0033] In order to further improve the structural strength of the connecting area between the connecting surface 10 and the supporting wall 30, as shown in FIG. Figure 1 As shown, the junction of the folded edge 33 and the connecting surface 10 is provided with a reinforcing support rib 31. The folded edge 33 serves as a boundary reinforcement structure on the supporting wall 30 and is connected to the connecting surface 10 through the reinforcing support rib 31, thereby preventing the area where the connecting surface 10 and the folded edge 33 meet from fracture due to stress concentration, thereby improving the structural strength.
[0034] For some possible implementations, see Figure 1 The limiting surface 20 has a supporting portion 21 extending away from the connecting surface 10 and adapted to pass through the center hole of the spare tire hub 60. The supporting portion 21 allows the spare tire hub 60 to be installed by first fitting the center hole of the spare tire hub 60 over the supporting portion 21 and then attaching the fastener 40, thereby reducing installation difficulty. Furthermore, the supporting portion 21 assists the fastener 40 in weighing the spare tire, thereby preventing the fastener 40 from breaking under stress and improving spare tire installation reliability.
[0035] It is important to understand that, combined with Figure 1 and Figure 3 It is understood that in this embodiment, the limiting surface 20 has a plurality of embedding holes 22 arranged in a circular array centered on the supporting portion 21. A fastener 40 is fixedly connected to each embedding hole 22. Typically, three or more fasteners 40 are used to securely connect the spare tire hub 60. The fasteners 40 hold the spare tire hub 60 against the limiting surface 20 and apply uniform force to the hub in the circumferential direction, thereby improving spare tire installation reliability.
[0036] In some embodiments, the fastener 40 is formed as follows: Figure 3 The structure shown includes a limiting end 41, an embedding section 42, and a threaded section 43 connected in sequence; wherein, the limiting end 41 is located on the side of the limiting surface 20 close to the connecting surface 10, and the limiting end 41 abuts against the limiting surface 20, the embedding section 42 is passed through the embedding hole 22 and has an interference fit with the embedding hole 22, and the threaded section 43 is suitable for passing through the mounting hole of the spare tire hub 60 and being screwed to the fastening nut 50.
[0037] The fastener 40 can be a fastener that uses a riveting method to press its embedded section 42 into the embedding hole 22 to form an interference fit until the limiting end 41 is against the limiting surface 20, and the threaded section 43 is used to insert into the mounting hole of the spare tire hub 60 after passing through the embedding hole 22, and is fixed with a fastening nut 50 after the threaded section 43 passes through the mounting hole, so that the spare tire hub 60 is tightly against the limiting surface 20. The connection method is simple and stable, and the disassembly and assembly operation is convenient; of course, in order to avoid relative rotation between the embedded section 42 and the embedding hole 22 when screwing the fastening nut 50, which increases the difficulty of operation, the embedding hole 22 and the embedded section 42 can adopt mutually matching non-circular cross-sectional structures, such as a polygonal hole and a polygonal cylinder or an elliptical hole and an elliptical cylinder.
[0038] Alternatively, see Figure 1 In this embodiment, the sidewall of the support portion 21 is grooved to form a cavity. The end of the cavity away from the limiting surface 20 forms a spare tire cover mounting surface 211. Because the support portion 21 passes through the center hole of the spare tire hub 60, the end of the support portion 21 serves as the spare tire cover mounting surface 211, facilitating the securement of the spare tire cover. Furthermore, the provision of the cavity in the support portion 21 facilitates weight reduction and facilitates die-casting.
[0039] On the basis of the above, if Figure 1 As shown, the opening of the cavity faces downward, and the opening of the cavity near the spare tire cover mounting surface 211 is sealed to form a camera mounting surface 212. For vehicles with a rear-mounted spare tire, to prevent the spare tire from blocking the camera's view, the rearview camera can be mounted on the spare tire mounting base (with the spare tire cover opening clear of the camera lens). Specifically, it is mounted on the camera mounting surface 212 on the lower side of the support portion 21, away from the vehicle body. This allows the mounting base to integrate the spare tire mounting, spare tire cover mounting, and camera mounting, thereby improving the integrated assembly of various components at the rear of the vehicle.
[0040] Based on the same inventive concept, an embodiment of the present application also provides a vehicle, including a vehicle and the above-mentioned spare tire mounting seat.
[0041] Compared with the prior art, the vehicle provided by the present invention adopts the above-mentioned spare tire mounting seat to fix the spare tire. The one-piece mounting seat body can eliminate the connecting welds between the components, avoid stress concentration and fracture at the weld position, thereby improving the structural strength of the mounting seat body and facilitating weight reduction. In addition, by arranging reinforcing support ribs 31 on the inner wall surface and / or outer wall surface of the supporting wall 30, the structural strength of the mounting seat body can be further improved, and the risk of stress fracture can be reduced, thereby improving the reliability of spare tire installation.
[0042] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
