[0032] like Figure 1 and Figure 2As shown, this embodiment provides a spare tire mounting bracket, including a bracket body 1 and several supports 2. The bracket body 1 includes a support portion 11, a connecting portion 12, and a fixing portion 13. The support portion 11 is configured as an annular structure for supporting the tire of the spare tire 300. The fixing portion 13 is located at the annular center of the support portion 11 and is configured as a boss protruding upward along the height direction z, for detachably and fixedly connected to the wheel hub of the spare tire 300. The connecting portion 12 is disposed between the support portion 11 and the fixing portion 13, with one end connected to the support portion 11 and the other end connected to the fixing portion 13. Several supports 2 surround and are fixed to the circumferential outer side of the support portion 11 for detachably and fixedly connected to the vehicle body 200. In this way, when there is a need for a spare tire, the support part 11 of the bracket body 1 can be used to support the tire of the spare tire 300, and the fixing part 13 of the bracket body 1 can be used to fix the wheel hub of the spare tire 300. The support part 11 and the fixing part 13 are connected as one unit through the connecting part 12, which can effectively support and fix the spare tire 300. At the same time, since the bracket body 1 is detachably fixed to the vehicle body 200 through the support 2, the spare tire fixing bracket 100 is detachable from the vehicle body 200. When there is no need for a spare tire, the bracket can be removed to increase the capacity of the vehicle's storage space.

[0033] For example, such as Figures 1 to 3As shown, the spare tire mounting bracket 100 can be detachably fixed in the trunk of the vehicle via the support 2. The detachable fixing connection can be achieved by opening corresponding bolt connection holes on the support 2 and the vehicle body 200, and then using bolt connection to achieve the detachable fixing connection between the spare tire mounting bracket 100 and the vehicle body 200. In this embodiment, the bracket body 1 is divided into a left front region 101, a right front region 102, a left rear region 103, and a right rear region 104 along the width direction y and the length direction x. The left front region 101 and the right front region 102 of the bracket body 1 are each provided with a support 2. Both the support 2 in the left front region 101 and the support 2 in the right front region 102 are connected to the front side of the bracket body 1. The bracket body 1 is connected forward to the vehicle body 200 (e.g., the rear seat mounting beam of the vehicle) via the supports 2 in the left front region 101 and the right front region 102. The right rear region 104 of the bracket body 1 is also provided with a support 2. The support 2 in the right rear region 104 is connected to the right side of the bracket body 1. The bracket body 1 is connected to the right side of the vehicle body 200 (e.g., the right side panel bracket or the right rear longitudinal beam of the vehicle) via the support 2 in the right rear region 104. This achieves the connection of the spare tire fixing bracket 100 to the vehicle body 200. The spare tire mounting bracket 100 is fixed and can provide multi-point support connection around the bracket body 1, ensuring the connection stability between the spare tire mounting bracket 100 and the vehicle body 200. At this time, the spare tire 300 is placed on the bracket body 1. The ring structure formed by the support part 11 can support the tire of the spare tire 300, so that the spare tire 300 installed on the bracket body 1 is evenly stressed, thereby improving the reliability of the spare tire 300 installed on the bracket body 1. The boss formed by the fixing part 13 corresponds to or abuts against the lower end face of the wheel hub of the spare tire 300. The top surface of the boss can be opened with at least one bolt connection hole corresponding to the size and dimensions of the wheel hub hole of the spare tire 300. The bolt fastener 131 is used to achieve a detachable fixed connection with the wheel hub of the spare tire 300 by bolt connection, ensuring that the connection between the spare tire 300 and the spare tire mounting bracket 100 does not fail in the collision impact.

[0034] It is understood that in other embodiments, at least one support 2 may be provided in the left rear region 103 of the bracket body 1, and the support 2 in the left rear region 103 may be connected to the left side of the bracket body 1, so that the bracket body 1 can be connected to the left side of the vehicle body 200 via the support 2 in the left rear region 103; or at least one support 2 may be provided in the left rear region 103 and the right rear region 104 of the bracket body 1, so that the bracket body 1 may be connected to the left and right sides of the vehicle body 200 via the support 2 in the left rear region 103 and the right rear region 104, respectively. The choice can be made according to the vehicle design requirements and specific needs, and there is no limitation here.

[0035] In some embodiments, such as Figures 1 to 3As shown, the support 2 located in the left front region 101 and the support 2 located in the right front region 102 can also be connected to each other as a whole. This can further improve the connection stability between the spare tire mounting bracket 100 and the vehicle body 200. The connection method between the two supports 2 is not limited to extending the two supports 2 to each other along the width direction y to connect them, or welding a connecting plate 21 extending along the width direction y between the two supports 2 to connect them, etc. Any method that can connect the two supports 2 to each other as a whole will not be described in detail here.

[0036] In some embodiments, such as Figure 1 and Figure 2 As shown, the bracket body 1 has a notch 14 in the left rear region 103 or the right rear region 104. The notch 14 extends from the outer periphery of the support part 11 to near the fixing part 13. With the setting of the notch 14, the user can reach under the bracket and lift the tire from the notch 14 when taking out or putting in the spare tire, which improves the convenience of taking out or putting in the spare tire. At the same time, it is also conducive to the lightweighting of the overall structure.

[0037] It is understandable that the opening area and opening angle of notch 14 can be optimized through topology analysis based on the setting orientation of support 2 and simulation results. No specific limitations are imposed here; for example, ... Figure 1 and Figure 3 As shown, in this embodiment, the support 2 is located in the right rear region 104 of the bracket body 1, and the notch 14 is located in the left rear region 103 of the bracket body 1. The notch 14 is opened at an angle of 60 degrees, which can meet the lightweight requirements of the bracket body 1 without affecting the connection stability between the spare tire mounting bracket 100 and the vehicle body 200. In other embodiments, when the support 2 is provided in the left rear region 103 of the bracket body 1, the notch 14 can also be opened in the right rear region 104 of the bracket body 1; when the support 2 is provided in both the left rear region 103 and the right rear region 104 of the bracket body 1, the notch 14 can also be opened on the central axis of the bracket body 1 about the length direction x, with a part of the notch 14 located in the left rear region 103 and the other part located in the right rear region 104.

[0038] In some embodiments, such as Figure 2 and Figure 3 As shown, the connecting part 12 has a plurality of hollow areas 121, which are distributed circumferentially around the fixing part 13. This can further meet the lightweight requirements of the bracket body 1 while meeting the requirements of rigidity, durability and NVH (Noise, Vibration, Harshness) standards.

[0039] Specifically, the connecting portion 12 can be formed as a single plate circumferentially distributed around the fixing portion 13, and lightweighting is achieved by constructing a hollow area 121 on the connecting portion 12. For example... Figure 3 As shown, in this embodiment, the hollow area 121 is constructed as a fan-shaped structure that is circumferentially spaced around the fixing part 13 and is arranged through the height direction z. Based on the arrangement of the hollow area 121, the connecting part 12 is also divided into multiple strip-shaped plate structures that are circumferentially spaced around the fixing part 13. The multiple strip-shaped plate structures can also correspond to the supports 2 located on the outer side of the support part 11, so that the transmission path of the supporting force is continuous and the support stability of the spare tire fixing bracket 100 for the spare tire 300 is guaranteed.

[0040] In some embodiments, such as Figure 2 and Figure 3 As shown, the spare tire mounting bracket 100 also includes a limiting member 3. The limiting member 3 protrudes from the upper surface of the bracket body 1 and extends circumferentially around the support portion 11, and is constructed as a ring shape that conforms to the outer circumferential surface of the spare tire 300. By setting the limiting member 3, the tire of the spare tire 300 placed on the bracket body 1 can be circumferentially limited in the horizontal plane (xy), distributing the horizontal force exerted by the spare tire 300 on the fixing portion 13 during driving, and ensuring the stable connection between the spare tire 300 and the spare tire mounting bracket 100.

[0041] In some embodiments, such as Figure 2 and Figure 6 As shown, a positioning groove 15 is provided at the connection between the support part 11 and the connecting part 12, which is recessed downward along the height direction z. The positioning groove 15 includes an outer groove wall 151, an inner groove wall 152, and a groove bottom 153. The upper surface of the support part 11 is inclined downward from the outside to the inside at the positioning groove 15 based on the circumferential outline of the bracket body 1 to form the outer groove wall 151. The upper surface of the connecting part 12 is inclined downward from the inside to the outside at the positioning groove 15 based on the circumferential outline of the bracket body 1 to form the inner groove wall 152. The groove bottom 153 connects the outer groove wall 151 and the inner groove wall 152, so that the support part 11 and the connecting part 12 are connected continuously. By setting the positioning groove 15, the bracket body 1 can have a guiding and centering function. When the spare tire 300 is placed on the bracket body 1, the tire of the spare tire 300 can slide along the outer groove wall 151 or the inner groove wall 152 towards the bottom of the groove 153. At this time, the spare tire 300 is centered and aligned with the bracket body 1, and the center area of ​​the spare tire 300's wheel hub can correspond to the fixing part 13 in the height direction z, thereby improving the convenience of matching and connecting the wheel hub of the spare tire 300 with the fixing part 13.

[0042] It is understandable that, since the support part 11 is constructed as a ring structure, regardless of whether the connecting part 12 is a whole plate distributed circumferentially around the fixing part 13, or a plurality of strip-shaped plate structures arranged circumferentially around the fixing part 13 and separated by the hollow area 121, the positioning groove 15 is in the ring shape distributed circumferentially around the fixing part 13 relative to the overall outline of the bracket body 1. In this way, the tire bottom tread of the spare tire 300 can be supported by the positioning groove 15, so as to achieve the centering of the guide for the placement of the spare tire 300.

[0043] In some embodiments, such as Figures 4 to 6 As shown, the lower surface of the support body 1 is also provided with a plurality of reinforcing ribs 16. The plurality of reinforcing ribs 16 extend inward from the support part 11 along the connecting part 12 with the circumferential contour of the support body 1 as a reference to the fixing part 13, and are distributed circumferentially at intervals in the fixing part 13. By setting the reinforcing ribs 16, the bending and torsional stiffness of the support body 1 can be improved, the force transmission of load and vibration can be optimized, and the deformation risk of the support body 1 can be reduced.

[0044] Furthermore, such as Figure 4 and Figure 5 As shown, several reinforcing ribs 16 are connected to the lower surface of the fixing part 13, and the connection is constructed as a circular cylinder 161. This can improve the connection stability and force transmission effect of the reinforcing ribs 16. At the same time, the multiple reinforcing ribs 16 distributed at intervals can intersect at the fixing part 13, improve the structural strength of the fixing part 13, and ensure that the fixing part 13 and the wheel hub of the spare tire 300 are firmly and effectively fixed.
