Technical Field
[0001] This utility model relates to the field of vehicle parts technology, specifically to a spare tire rack panel. Background Technology
[0002] As a crucial part of the tire carrier that directly contacts the tire, the spare tire carrier panel plays a vital role in tire storage, securing, and protection. Its material, structure, and functional characteristics are interconnected, collectively ensuring the performance of the tire carrier. In automotive applications, off-road vehicles and trucks often have additional spare tire carriers to suspend the spare tire. For example, patent application CN201610916372.8, entitled "A Spare Tire Support Structure," utilizes a wheel rim mounting bracket for threaded connection to the tire. However, the size and number of connection holes of spare tires often differ between different vehicle models. This necessitates the production of spare tire carrier panels of varying specifications to accommodate different sized spare tires, resulting in higher production costs. Utility Model Content
[0003] The purpose of this utility model is to provide a spare tire rack panel, which aims to improve the problem of high production costs caused by the need to produce spare tire rack panels of different specifications to adapt to spare tires of different sizes.
[0004] To achieve the above objectives, the present invention adopts the following technical solution:
[0005] A spare tire rack panel includes a panel body, wherein the panel body has a plurality of connecting holes adapted to connecting bolts, the connecting holes including:
[0006] A positioning hole is provided on one side of the panel body and is used to position a hole for connecting the tire hole.
[0007] At least one pair of radial holes are provided on the other side of the panel body. Each pair of radial holes is a radial elongated hole relative to the positioning hole and is symmetrically distributed relative to the positioning hole to assist in connecting the other two holes of the tire hole.
[0008] Furthermore, each pair of radial holes includes a pair of first radial holes, the position and length of which are adapted to the tire holes of a five-hole wheel hub with a screw hole pitch circle diameter of 4.5 inches, 4.75 inches, and 5 inches, and the two holes furthest from the hole position located by the positioning hole.
[0009] Furthermore, the angle between the centerline of the first radiating hole and the centerline of the positioning hole is 18°, the distance between the first radiating hole and the inner wall of the positioning hole is not greater than 98.7 mm, and the distance between the first radiating hole and the outer wall of the positioning hole is not less than 130.8 mm.
[0010] Furthermore, each pair of radial holes includes a pair of second radial holes, the position and length of which are adapted to two holes in the tire holes of a six-hole wheel hub with a screw hole pitch circle diameter of 5.32 inches and 5.5 inches, which are distributed in an equal triangle with the positioning holes.
[0011] Furthermore, the angle between the centerline of the second radiating hole and the centerline of the positioning hole is 30°, the distance between the second radiating hole and the inner wall of the positioning hole is not greater than 106.9 mm, and the distance between the second radiating hole and the outer wall of the positioning hole is not less than 131.0 mm.
[0012] Furthermore, it also includes a central radial hole, which is located on the other side of the panel body. The central radial hole is collinear with the positioning hole to connect the symmetrical holes of the holes connected by the positioning hole, so as to adapt to the holes symmetrical to the holes positioned by the positioning hole in the tire holes of four-hole wheel hubs with screw hole pitch circle diameters of 4 inches, 4.25 inches and 4.5 inches and / or six-hole wheel hubs with screw hole pitch circle diameters of 4.5 inches.
[0013] Furthermore, the distance between the central radiating hole and the inner wall of the positioning hole is not greater than 91.6 mm, and the distance between the central radiating hole and the outer wall of the positioning hole is not less than 124.3 mm.
[0014] Furthermore, it also includes a pair of first auxiliary connecting holes, which are located on both sides below the central radial hole to adapt to two holes adjacent to the holes connected to the central radial hole in the tire bolt holes of a six-hole wheel hub with a bolt hole pitch circle diameter of 4.5 inches.
[0015] Furthermore, it also includes a pair of second auxiliary connecting holes, which are located between the central radial hole and the positioning hole and are distributed in a figure-eight pattern to adapt to the remaining two holes in the tire hole positions of a four-hole wheel hub with a screw hole pitch circle diameter of 4 inches, 4.25 inches and 4.5 inches.
[0016] Furthermore, it also includes a pair of third auxiliary connecting holes, which are located on both sides above the positioning hole and, together with the central radial hole, are adapted to the tire hole position of the six-hole wheel hub with a screw hole pitch circle diameter of 4.5 inches.
[0017] By adopting the above technical solution, this utility model has the following advantages compared with the prior art:
[0018] 1. The positioning holes correspond to the first hole of the tire; each pair of radial holes corresponds to the second and third holes of the tire. Through its own elongated strip space, it covers the second and third holes of tires of different sizes, ensuring that each pair of radial holes meets the connection requirements of the second and third holes of tires of different sizes. This forms a three-point connection structure between the tire and the panel body, ensuring the firmness of the tire connection. At the same time, it enables a single panel body to adapt to tires of different sizes, reducing production costs.
[0019] 2. Each pair of radial holes and positioning holes are located on both sides of the panel body, which effectively increases the connection range of the three-point connection structure and further enhances the connection firmness of the tire; at the same time, each pair of radial holes is symmetrically distributed relative to the positioning holes to ensure that the tire is subjected to uniform force and improves the stability of the tire after installation.

[0051] Example
[0052] Please refer to the appendix. Figure 1-22 This embodiment discloses a spare tire rack panel; please refer to the attached document. Figure 1 and Figure 2 The system includes a panel body 1, on which a plurality of connecting holes 11 adapted for connecting bolts are formed. The connecting holes 11 are characterized in that each connecting hole 11 includes a positioning hole 111 and at least one pair of radial holes 112. The positioning hole 111 is located on one side of the panel body 1 and is used to position one of the holes for connecting the tire mounting holes. Each pair of radial holes 112 is located on the other side of the panel body 1, and each pair of radial holes 112 is an elongated radial hole relative to the positioning hole 111, and is symmetrically distributed relative to the positioning hole 111 to assist in connecting the other two holes for connecting the tire mounting holes.
[0053] The positioning hole 111 corresponds to the first hole of the tire; each pair of radial holes 112 corresponds to the second and third holes of the tire. Through its own elongated strip space, it covers the second and third holes of tires of different sizes, ensuring that each pair of radial holes 112 meets the connection requirements of the second and third holes of tires of different sizes, so that a three-point connection structure is formed between the tire and the panel body 1, ensuring the firmness of the tire connection, while realizing that a single panel body 1 can adapt to tires of different sizes, reducing production costs.
[0054] Furthermore, each pair of radial holes 112 and positioning holes 111 are located on both sides of the panel body 1, which effectively increases the connection range of the three-point connection structure and further enhances the connection firmness of the tire; at the same time, each pair of radial holes 112 is symmetrically distributed relative to the positioning holes 111, ensuring that the tire is subjected to uniform force at all points and improving the stability of the tire after installation.
[0055] In a specific example, each pair of radial holes 112 includes a pair of first radial holes 1121. The position and length of the first radial holes 1121 are adapted to the tire bolt positions of a five-hole wheel hub with bolt hole pitch circle diameters of 4.5 inches, 4.75 inches, and 5 inches, and are the two bolt positions furthest from the position positioned by the positioning hole 111. That is, the first radial holes 1121 connect the two bolt positions furthest from the first bolt position in the tire bolt positions, ensuring the connection range of the three-point connection structure and ensuring high installation strength of the tire. Please refer to [reference needed].

[0056] Please refer to Figure 3 As shown, specifically, the angle between the centerline of the first radial hole 1121 and the centerline of the positioning hole 111 is 18°. The distance H1 between the first radial hole 1121 and the inner wall of the positioning hole 111 is no greater than 98.7 mm, and the distance H2 between the first radial hole 1121 and the outer wall of the positioning hole 111 is no less than 130.8 mm. In this embodiment, the distance H1 between the first radial hole 1121 and the inner wall of the positioning hole 111 is 94.7 mm, and the distance H2 between the first radial hole 1121 and the outer wall of the positioning hole 111 is 135.3 mm, which satisfies the installation of tires with five-hole hubs and screw hole pitch circle diameters of 4.5 inches, 4.75 inches, and 5 inches. Similarly, other dimensions can be set to meet the installation of more tire specifications.
[0057] In a specific example, each pair of radial holes 112 includes a pair of second radial holes 1122. The position and length of the second radial holes 1122 are adapted to two holes in a six-hole wheel hub with a screw hole pitch circle diameter of 5.32 inches or 5.5 inches, which are equilaterally triangularly distributed with the positioning holes 111. Please refer to... Figure 3 As shown, specifically, the angle between the centerline of the second radial hole 1122 and the centerline of the positioning hole 111 is 30°. The distance H3 between the second radial hole 1122 and the inner wall of the positioning hole 111 is no greater than 106.9 mm, and the distance H4 between the second radial hole 1122 and the outer wall of the positioning hole 111 is no less than 131.0 mm. That is, the second radial hole 1122 is located outside the first radial hole 1121, further improving the understanding range of the three-point connection structure and enhancing the tire's installation strength. In this embodiment, the distance H3 between the second radial hole 1122 and the inner wall of the positioning hole 111 is 102.7 mm, and the distance H4 between the second radial hole 1122 and the outer wall of the positioning hole 111 is 135.5 mm, satisfying the installation of tires with six-hole hubs and screw hole pitch circle diameters of 5.32 inches and 5.5 inches. Similarly, other dimensions can be set to accommodate more tire specifications. Please refer to... Figure 10 and Figure 11 As shown, the tire of a six-hole wheel hub with a pitch circle diameter of 5.32 inches can be secured via the second radial hole 1122 and the positioning hole 111. Please refer to... Figure 12 and Figure 13 As shown, the tire of a six-hole wheel hub with a pitch circle diameter of 5.5 inches can be fixed through the second radial hole 1122 and the positioning hole 111.
[0058] In a specific example, a central radial hole 1123 is also included. The central radial hole 1123 is located on the other side of the panel body 1. The central radial hole 1123 is collinear with the positioning hole 111 to connect the symmetrical holes of the holes 11 connected by the positioning hole 111. This is to adapt to the symmetrical holes in the tire bolt positions of four-hole wheel hubs with bolt hole pitch circle diameters of 4 inches, 4.25 inches, and 4.5 inches, and / or six-hole wheel hubs with bolt hole pitch circle diameters of 4.5 inches, corresponding to the holes positioned by the positioning hole 111. That is, the central radial hole 1123 and the positioning hole 111 meet the installation requirements of four-hole wheel hubs with bolt hole pitch circle diameters of 4 inches, 4.25 inches, and 4.5 inches, and six-hole wheel hubs with bolt hole pitch circle diameters of 4.5 inches. Furthermore, the positioning hole 111 and the central radial hole 1123 are located at both ends of the wheel hub diameter, providing a large installation distance and effectively ensuring tire installation stability. Please refer to [reference needed]. Figure 3 As shown, specifically, the distance H5 between the central radial hole 1123 and the inner wall of the positioning hole 111 is no greater than 91.6 mm, and the distance H6 between the central radial hole 1123 and the outer wall of the positioning hole 111 is no less than 124.3 mm. In this embodiment, the distance H5 between the central radial hole 1123 and the inner wall of the positioning hole 111 is 88.8 mm, and the distance H6 between the central radial hole 1123 and the outer wall of the positioning hole 111 is 127.1 mm, which satisfies the installation requirements of tires with four-hole hubs and screw hole pitch circle diameters of 4 inches, 4.25 inches, and 4.5 inches, and tires with six-hole hubs and screw hole pitch circle diameters of 4.5 inches. Similarly, other dimensions can be set to accommodate the installation of more tire specifications. Please refer to...

The first auxiliary connecting holes 113 are located on both sides below the central radial hole 1123 to accommodate two adjacent holes in a tire bolt hole of a six-hole wheel hub with a bolt hole pitch circle diameter of 4.5 inches. The first auxiliary connecting holes 113, together with the central radial hole 1123 and the positioning hole 111, form a four-point connection structure. Similarly, a three-point connection structure can be formed for a six-hole wheel hub using only the first auxiliary connecting holes 113 and the positioning hole 111, ensuring the stability of tire installation. Please refer to [reference needed]. Figure 18 As shown, the tire of a six-hole wheel hub with a pitch circle diameter of 4.5 inches can be fixed through the first auxiliary connecting hole 113, the central radial hole 1123 and the positioning hole 111.

The second auxiliary connecting holes 114, together with the central radial hole 1123, form a three-point connection structure for the tire. Similarly, a strip-shaped positioning hole 111 can be provided to form a four-point connection structure for the tire, ensuring the stability of the tire installation. Please refer to [reference needed].
