Description

Technical Field

[0001] This utility model relates to the field of tire technology, specifically a lightweight safety tire support assembly. Background Technology

[0002] Tire safety is paramount during vehicle operation. Traditional tires, when subjected to punctures or blowouts, often lead to loss of vehicle control and traffic accidents. To improve tire safety, various safety tire designs have emerged, one common design being the addition of internal supports to allow the vehicle to continue traveling a certain distance even when the tire loses air pressure, ensuring a safe stop.

[0003] However, existing tire support designs have many shortcomings. Some supports are made of materials such as rubber, which, while improving the tire's load-bearing capacity to some extent, also increase weight, raising vehicle energy consumption. Furthermore, they are prone to deformation under prolonged high-load conditions, affecting their support effectiveness. Other supports employ a one-piece design, making installation and disassembly inconvenient, maintenance costs high, and difficult to adjust flexibly according to actual needs. In addition, the design of the contact surface between the existing support and the tire is unreasonable, easily causing cutting action on the tire, shortening its lifespan, and even posing safety hazards.

[0004] Therefore, this utility model provides a lightweight support assembly for a safety tire. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this utility model provides a lightweight support assembly for safety tires, aiming to solve the aforementioned problems.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: a lightweight safety tire support assembly, including a support body, wherein the support body is provided in three sets, the three sets of support bodies are connected end to end to form a ring, and a set of connectors is installed between adjacent sets of support bodies, and a total of three sets of connectors are provided.

[0007] The connector includes a connecting plate with a set of circular holes and a set of rounded rectangular holes on its surface. A wedge is installed in the rounded rectangular holes. A threaded hole is provided on the surface of the wedge. A set of bolts is threaded into both the threaded hole and the circular hole on the surface of the connecting plate. A washer is installed between the bolt and the connecting plate. The tail end of the bolt passing through the circular hole is threaded into a first base plate, and the tail end of the bolt passing through the wedge is threaded into a second base plate.

[0008] Preferably, the support body includes a lower support surface, a plurality of web plates are fixedly connected to the top of the lower support surface, an upper support surface is fixedly connected to the top of the plurality of web plates, and a plurality of blocks are symmetrically fixed on both sides of the lower support surface.

[0009] Preferably, mounting grooves are provided on the sides of the plates at both ends, a first limiting groove is provided on the surface of the plate at one end, and a second limiting groove is provided on the surface of the plate at the other end. The first limiting groove and the second limiting groove are both connected to the corresponding mounting grooves.

[0010] Preferably, the wedge is a split design, consisting of a large and a small combination, with the smaller part being secured in the mounting groove and the larger part being inserted into the corresponding first limiting groove.

[0011] Preferably, the first limiting groove corresponds to the side of the connecting plate with the rounded rectangular hole, and the second limiting groove corresponds to the side of the connecting plate with the circular hole. The two ends of the connecting plate are respectively inserted into the mounting grooves corresponding to the two adjacent sets of the support bodies, so as to realize the combined installation of the connecting piece and the support body.

[0012] Beneficial effects Compared with the prior art, the present invention has the following advantages: 1. The support structure of this utility model adopts a three-section installation structure. The three sections of the support are completely identical and interchangeable, which facilitates the assembly and maintenance of the support. The connecting parts adopt a wedge-shaped connecting block with a connecting plate installation method.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figures 1-5 A lightweight safety tire support assembly includes a support body 1, which has three sets. The three sets of support bodies 1 are connected end to end to form a ring, and a set of connectors 2 is installed between two adjacent sets of support bodies 1. There are a total of three sets of connectors 2.

[0018] The connector 2 includes a connecting plate 21. The surface of the connecting plate 21 has a set of circular holes and a set of rounded rectangular holes. A wedge 23 is installed in the rounded rectangular holes. The surface of the wedge 23 has a threaded hole. A set of bolts 24 are threaded into both the threaded hole and the circular hole on the surface of the connecting plate 21. A washer 22 is installed between the bolts 24 and the connecting plate 21. The tail end of the bolt 24 passing through the circular hole is threaded to a first base plate 25. The tail end of the bolt 24 passing through the wedge 23 is threaded to a second base plate 26.

[0019] It should be noted that the connector 2 is installed in the grooves pre-cut on the sides of the two adjacent sets of support bodies 1. Each set of connector 2 is fixed by bolts 24. The use of the first base plate 25 and the second base plate 26 can effectively limit the bolts 24. The design of the three sets of support bodies 1 makes the whole assembly easy to disassemble and replace, simplifies the installation process, and improves safety.

[0020] In one embodiment of this utility model, such as Figures 1-5 As shown, the support body 1 includes a lower support surface 11, a number of web plates 12 are fixedly connected to the top of the lower support surface 11, an upper support surface 13 is fixedly connected to the top of the web plates 12, and a number of blocks 17 are symmetrically fixed on both sides of the lower support surface 11.

[0021] Specifically, three identical 120° sector-shaped support bodies 1 are installed together by connectors 2 and fixed on the mounting groove of the wheel rim support surface to form a complete circle. When driving without tire pressure, the inner side of the tire crown contacts the upper support surface 13 of the support body 1, and the load-bearing force is transmitted through the support body 1.

[0022] The upper support surface 13 is arc-shaped and contacts the inner side of the tire, effectively bearing the load while preventing damage to the inner rubber of the tire crown; the lower support surface 11 cooperates with the support body mounting interface on the rim to ensure load-bearing stability; the spoke 12 is a load-bearing component connecting the upper support surface 13 and the lower support surface 11, with a main load-bearing rib and auxiliary rib structure, effectively achieving lightweight design under high load; the blocks 17 set on the inner and outer sides of the support body 1 are used to prevent the tire support ring from becoming unstable when driving with a deflated tire.

[0023] In one embodiment of this utility model, such as Figures 1-5 As shown, mounting grooves 14 are provided on the sides of the two ends of the web plate 12. A first limiting groove 15 is provided on the surface of the web plate 12 at one end, and a second limiting groove 16 is provided on the surface of the web plate 12 at the other end. The first limiting groove 15 and the second limiting groove 16 are connected to the corresponding mounting grooves 14.

[0024] In one embodiment of this utility model, such as Figures 1-5 As shown, the wedge 23 is a split design, consisting of a large and a small combination. The smaller part is locked in the mounting groove 14, while the larger part is inserted into the corresponding first limiting groove 15.

[0025] Specifically, during installation, as the bolt 24 is screwed in, the larger part of the wedge 23 compresses the smaller part within the first limiting groove 15 to achieve assembly. This split assembly method can effectively fix the support body 1 and ensure its installation stability on the wheel rim.

[0026] In one embodiment of this utility model, such as Figures 1-5 As shown, the first limiting groove 15 corresponds to the side of the connecting plate 21 with the rounded rectangular hole, and the second limiting groove 16 corresponds to the side of the connecting plate 21 with the circular hole. The two ends of the connecting plate 21 are respectively inserted into the mounting grooves 14 corresponding to the two adjacent sets of support bodies 1, so as to realize the combined installation of the connecting piece 2 and the support body 1.

[0027] Specifically, when installing the connector 2 and the support 1, the connecting plate 21 is inserted into the mounting groove 14, so that the end of the connecting plate 21 with the rounded rectangular hole corresponds to the first limiting groove 15. Then, the smaller part of the wedge 23 is inserted into the mounting groove 14, and the larger part of the wedge 23 is inserted into the first limiting groove 15. Then, the two sets of washers 22 are placed on the surface of the bolt 24 and the bolt 24 is tightened to fix the connecting plate 21 and the wedge 23. The rear ends of the two sets of bolts 24 pass through the first base plate 25 and the second base plate 26 respectively to fix the connector 2 and the support 1.

[0028] The support body 1 is made of aluminum alloy, which is lightweight and effectively reduces vehicle energy consumption and improves vehicle driving efficiency. The support body 1 has an I-shaped cross-section, and the web plate 12 adopts a main load-bearing rib plus auxiliary rib structure, realizing a lightweight design under high load and meeting the load-bearing requirements of the vehicle under various working conditions. Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0029] Working principle: During operation, three sets of support bodies 1 are connected end to end by connectors 2 to form a ring, and are fixed on the mounting groove of the wheel rim support surface to form a complete circle. When the tire loses air pressure, the inner side of the tire crown contacts the upper support surface 13 of the support body 1, and the load-bearing force is transmitted through the support body 1, allowing the vehicle to continue to travel a certain distance and ensuring safe parking.

[0030] During installation, the connecting plate 21 is inserted into the mounting groove 14, with the end of the connecting plate 21 having a rounded rectangular hole corresponding to the first limiting groove 15. Next, the smaller portion of the wedge 23 is inserted into the mounting groove 14, and then the larger portion of the wedge 23 is inserted into the first limiting groove 15. As the bolt 24 is screwed in, the larger portion of the wedge 23 presses against the smaller portion in the first limiting groove 15, achieving a combination. This split-assembly method effectively fixes the components and ensures the stability of the support 1 on the wheel rim. Then, two sets of washers 22 are fitted onto the surface of the bolt 24, and the bolt 24 is tightened to fix the connecting plate 21 and the wedge 23. The rear ends of the two sets of bolts 24 pass through the first base plate 25 and the second base plate 26 respectively, further enhancing the fixing effect on the connector 2 and the support 1.
