[0008] According to one embodiment of the present invention, the reinforcing horizontal tube is a circular steel tube with the same diameter as the left connecting tube and the right connecting tube. A triangular reinforcing rib is provided at the connection between the reinforcing horizontal tube and the left connecting tube and the right connecting tube, and the reinforcing rib is fixed by welding.

[0009] According to one embodiment of the present invention, the left connecting pipe, the right connecting pipe, the inner protective plate and the reinforcing horizontal pipe are all provided with multiple assembly brackets.

[0010] According to one embodiment of the present invention, the folded edge length of the inner protective plate and the outer protective plate is 10mm-15mm, and a sealing strip is provided at the overlap, the sealing strip being made of aging-resistant rubber.

[0011] Compared with the prior art, the present invention can achieve the following technical effects: The left and right connecting tubes are bent and gradually approach each other at the bottom, forming a triangular stable structure with the reinforcing horizontal tube, which improves the overall impact resistance. In the square cavity formed by the inner and outer protective plates, the EVA buffer material liner can effectively absorb impact energy through the surface buffer holes, reducing the impact on the frame and body; the outer removable ABS liner has high hardness and can directly resist external damage such as sand and gravel and collisions.

[0012] Of course, any product implementing this utility model does not necessarily need to achieve all of the above-mentioned technical effects at the same time. Attached Figure Description

Detailed Implementation

[0016] The following will describe in detail the implementation of this utility model with reference to the accompanying drawings and embodiments, so that the implementation of this utility model can be fully understood and carried out based on how technical means are used to solve technical problems and achieve technical effects.

[0017] Please refer to Figure 1 , Figure 1This is a perspective view of a stable and safe rear bumper according to an embodiment of this utility model.

[0018] As shown in the figure, a sturdy and safe rear bumper includes: a left connecting pipe 10 and a right connecting pipe 20, which are connected to the rear side of the frame of a four-wheeled off-road motorcycle and are bent, with the lower sections gradually approaching each other; an inner protective plate 40 and an outer protective plate 30 at the lower ends of the left connecting pipe 10 and the right connecting pipe 20 are connected by welding, and the upper and lower edges of the inner protective plate 40 and the outer protective plate 30 are folded and overlapped with each other; and a reinforcing horizontal pipe 50 connecting the middle sections of the left connecting pipe 10 and the right connecting pipe 20; wherein, a square cavity 51 is provided in the middle of the inner protective plate 40 and the outer protective plate 30, and multiple hollow holes 52 are provided around the perimeter; an inner lining plate 60 is provided in the square cavity 51, and a detachable ABS outer lining plate 70 is fixed to the outside by bolts; the surface of the ABS outer lining plate 70 is provided with multiple guide grooves 71 and reflective embossed textures 72.

[0019] In one embodiment of this utility model, the left connecting pipe 10 and the right connecting pipe 20 are symmetrically designed. The upper end is connected to the middle of the frame of the four-wheeled off-road motorcycle. The middle section is welded with a reinforcing horizontal pipe 50 to enhance support. The lower end is welded together with an inner protective plate 40 and an outer protective plate 30 to improve the overall lateral stability.

[0020] The inner protective plate 40 and the outer protective plate 30 are aligned front and rear. One side is welded and fixed to the left connecting pipe 10 and the right connecting pipe 20, while the other side has its edges folded over and overlapped, allowing for welding to ensure a tight seal. A square cavity 51 is provided in the middle to fill the inner liner 60, enhancing impact resistance. Multiple external perforations 52 reduce weight and serve as mounting holes for the outer plastic shell of the vehicle frame. The ABS outer liner 70 is bolted to the outside of the outer protective plate 30, further enhancing protection. Simultaneously, the drainage channel 71 facilitates the drainage of mud and water, while the reflective embossed pattern 72 enhances the warning effect.

[0021] The inner liner 60 is made of EVA cushioning material with a thickness of 10mm-15mm and has multiple cushioning holes with a diameter of 3mm-5mm on its surface. The surface cushioning holes can effectively absorb impact energy and reduce the impact on the frame and body.

[0022] The ABS outer liner 70 has a thickness of 8mm-12mm. The guide channels 71 are angled downwards, numbering 3-5, with a depth of 2mm-4mm and a width of 5mm-8mm. The reflective embossed texture 72 is triangular or rhomboid, with a height of 1mm-2mm. It has high hardness and can directly resist external damage such as sand and gravel and impacts.

[0023] The reinforcing horizontal tube 50 is a circular steel tube with the same diameter as the left connecting tube 10 and the right connecting tube 20. Triangular reinforcing ribs are provided at the connection between the reinforcing horizontal tube 50 and the left connecting tube 10 and the right connecting tube 20. The reinforcing ribs are fixed by welding to further enhance the connection strength and reduce deformation under stress.

[0024] The left connecting pipe 10, the right connecting pipe 20, the inner protective plate 40, and the reinforcing horizontal pipe 50 are all equipped with multiple mounting brackets, which facilitates the overall fixing to the vehicle body and makes it easy to install the plastic protective shell.

[0025] The folded edges of the inner protective plate 40 and the outer protective plate 30 are 10mm-15mm long, and a sealing strip is provided at the overlap. The sealing strip is made of aging-resistant rubber. The folding forms a double-layer protective structure, and the sealing strip at the overlap enhances the overall structural integrity and also provides dust and water protection. The sealing strip is made of aging-resistant rubber, and the inner lining plate uses a cushioning structure to reduce performance degradation after long-term use, extending the overall service life.

[0026] In summary, the left and right connecting pipes of this utility model are bent and gradually approach each other at the bottom, forming a triangular stable structure with the reinforcing horizontal pipe, thus improving the overall impact resistance. Within the square cavity formed by the inner and outer protective plates, the EVA buffer material liner effectively absorbs impact energy through surface buffer holes, reducing the impact on the frame and body; the outer removable ABS liner has high hardness and can directly resist external damage such as sand and gravel, and collisions.
