Description

Technical Field

[0001] This utility model relates to the field of trailer caravan bumper technology, specifically a novel integrated rear bumper for trailer caravan spare tire. Background Technology

[0002] The rear bumper of a towed caravan is primarily for reducing collisions during daily driving, thus preventing damage to the vehicle body. However, some towed caravan rear bumpers on the market have several drawbacks, such as: 1. Limited extension of the rear bumper, lacking practicality for travel and accommodation. 2. Insufficient structural strength of the rear bumper, resulting in slightly weaker load-bearing capacity. 3. Some towed caravan rear bumpers are directly attached to the vehicle body, damaging the rear wall structure. 4. Insufficient protection space for the spare tire. Utility Model Content

[0003] Purpose of the utility model: To provide a novel integrated rear bumper for spare tires in towed caravans, in order to solve the problems of strength and practicality of rear bumpers for towed caravans mentioned in the background art.

[0004] Technical solution: A novel integrated spare tire rear bumper for a trailer caravan includes a caravan frame, a rear bumper is provided on the rear surface of the caravan frame, the rear bumper is fixedly connected to the caravan frame by U-shaped U-bolts, and the rear bumper extends beyond the vehicle body by a certain distance.

[0005] Furthermore, the rear bumper is composed of longitudinal steel tubes and transverse steel tubes, with four longitudinal steel tubes and one transverse steel tube.

[0006] Furthermore, a gasoline bottle mounting bracket is fixedly connected above the rear bumper via the U-shaped U-bolts, and a spare tire bracket is fixedly connected to the outer wall of the vehicle frame, with a spare tire mounted on the outer wall of the spare tire bracket.

[0007] Beneficial Effects: This utility model achieves a dual improvement in space expansion and load-bearing capacity through an optimized design of the integrated rear bumper structure for the spare tire of a trailer caravan. Specifically, the rear bumper adopts an extended design, with its bottom frame extending downwards beyond the vehicle's outline, forming an independent usable storage or installation space above the bumper. This facilitates the modular integration of functional components such as gasoline bottle holders and spare tire holders, effectively enhancing the vehicle's off-road range and emergency response capabilities.

[0008] In terms of load-bearing structure, an innovative matrix structure is adopted, formed by welding high-strength steel pipes into left and right longitudinal support frames and transverse connecting steel pipes. The weld distribution optimized through finite element analysis significantly improves the overall load-bearing strength of the structure. Combined with a multi-point fastening scheme using U-shaped saddle bolts at the bottom, the stability of the device is ensured under complex road conditions. Regarding installation, a non-intrusive installation technique is employed, with all connection nodes located in pre-reserved reinforcement positions on the chassis frame to avoid structural damage to the vehicle body while facilitating disassembly and maintenance. This design balances functional expansion with vehicle body integrity protection, providing a safe and reliable rear protection and functional integration solution for towed caravans.

[0013] To make the technical solution of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0014] Example

[0015] like Figures 1-3 As shown, a novel integrated spare tire rear bumper for a caravan is provided. The rear bumper 1 consists of four longitudinal steel pipes 5 on the left and right sides and a single transverse steel pipe. The rear bumper 1 is connected to the bottom of the caravan frame 2 via U-shaped bolts, and the rear bumper 1 extends beyond the car body by a certain distance. A gasoline bottle bracket 4 and a spare tire bracket 3 are installed above the longitudinal steel pipes 5 in the rear bumper via U-shaped bolts 6, for holding a gasoline bottle and a spare tire 7.

[0016] like Figure 1 Figure 2 As shown, the rear bumper 1 extends beyond the vehicle body by a certain distance and is connected to the box frame 2 by U-shaped U-bolts. The rear bumper 1 is composed of two steel pipes on the left and right sides and a horizontal steel pipe.

[0017] In this embodiment, as Figure 3As shown, a gasoline bottle holder 4 and a spare tire holder 3 are installed above the rear bumper 1, holding a gasoline bottle and a spare tire 7.

[0018] First, the left and right longitudinal steel pipes 5 and the transverse steel pipes in the rear bumper are welded together to form the main body of the rear bumper. Then, they are connected to the bottom of the vehicle frame using U-shaped bolts, extending a certain distance beyond the vehicle body to provide additional space. A gasoline bottle bracket 4 and a spare tire bracket 3 are installed above the steel pipes 5 in the rear bumper using U-shaped bolts 6 to hold the gasoline bottle and spare tire 7. This utility model of an integrated spare tire rear bumper for a trailer caravan separates the rear bumper from the vehicle body, preventing collisions and providing protection for the spare tire, thus avoiding future maintenance hassles. The high-strength steel pipes connected to the vehicle frame ensure that the rear bumper can bear a certain weight after extending a certain distance, expanding the external space of the vehicle body and reducing the burden on the internal space. Customers can arrange the space as they see fit, enhancing functionality and playability.

[0019] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
