[0002] In recent years, with the rise of outdoor sports, off-road motorcycle challenges have become increasingly popular among young people. Off-road motorcycles, also known as two-wheeled motorcycles, are traditionally used for riding on complex terrains such as mountainous areas. If the engine bottom at the bottom of the frame is not protected, it will be easily damaged by flying stones, dirt, and other foreign objects, which will cause damage to the frame bottom tubes or the engine bottom case, seriously affecting the service life of the off-road motorcycle engine. Utility Model Content

[0003] The purpose of this utility model is to address the shortcomings of the existing technology by providing an engine anti-collision structure for off-road motorcycles that is easy to disassemble and assemble. This addresses the issue mentioned in the background art that traditional off-road motorcycles are mainly used for driving on complex terrains such as outdoor mountains. If the engine bottom at the bottom of the frame is not protected, it will be easily subjected to the splashing and impact of foreign objects such as stones and dirt, which will cause damage to the frame bottom beam tube or the engine bottom shell, seriously affecting the service life of the off-road motorcycle engine.

[0006] The side plate structure includes a side plate body with a through hole, and the side plate body is welded and fixed to the bottom plate body. At the same time, a protective pad is also installed and fixed on the outer surface of the side plate body.

[0007] By adopting the above technical solution, the filter screen provides protection.

[0008] Preferably, there are 8 through slots, and the through slots are distributed on the surface.

[0009] By adopting the above technical solution, the through groove is used to achieve internal fixed installation.

[0010] Preferably, the protective pad is made of felt material, and the thickness of the protective pad is set to be in the range of 3-5cm.

[0011] By adopting the above technical solution, the protective pads installed provide bottom protection.

[0012] Preferably, one set of side plates is provided, and the side plates are symmetrically arranged about the axis of the base plate.

[0013] By adopting the above technical solution, the side plate body is used to achieve inlay welding and fixation.

[0014] Preferably, the through holes are provided in two sets, and each set of through holes is symmetrically provided about the surface of the side plate.

[0015] By adopting the above technical solution, a through-hole is created to achieve a through-connection.

[0016] Compared with the prior art, the beneficial effects of this utility model are: the engine anti-collision structure of this off-road motorcycle is easy to disassemble and assemble.

[0017] (1) This case solves the problem of traditional off-road motorcycles being mainly driven on complex roads such as outdoor mountains. If the engine bottom at the bottom of the frame is not protected, it will be easily hit by flying stones, dirt and other foreign objects, which will cause damage to the frame bottom beam tube or engine bottom shell, seriously affecting the service life of the off-road motorcycle engine. The base plate protects the bottom of the off-road motorcycle engine, and the protective pad set at the bottom of the base plate isolates and waterproofs the base plate, thus avoiding the damage to the frame bottom beam tube or engine bottom shell caused by flying stones, dirt and other foreign objects during the off-road motorcycle driving.

[0018] (2) By setting the side plate structure, the above problems are solved. It also makes it convenient for the operator to use the connecting bolt group through the through hole to wrap and protect the bottom and side of the engine with the whole side plate and bottom plate. At the same time, the side plate and through the through hole through the connecting bolt group also facilitate the quick installation and disassembly of the whole side plate and bottom plate with the bottom of the engine.

[0024] 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.

[0025] Please see Figure 1-4 This utility model provides a technical solution: an engine anti-collision structure for off-road motorcycles that is easy to disassemble and assemble, such as... Figure 1 , Figure 2 and Figure 3 As shown, the structure includes a base plate structure 1, which comprises a base plate body 101 with through slots 102 extending through it. Eight through slots 102 are provided, distributed across the surface. The presence of eight slots not only demonstrates the practicality of the structure's design but also its internal fixation and installation capabilities. Furthermore, the eight slots also reflect the distributed nature of the structure and its ventilation and heat dissipation properties. A filter screen 103 is fixedly installed inside each through slot 102, and a [missing information - likely a device or component] is fixedly installed at the bottom of the base plate body 101 using glue or nuts. The protective pad 104 is made of felt material and its thickness ranges from 3 to 5 cm. The use of felt material for the above-mentioned components not only reflects the practicality of the installation but also the waterproofness of the installation. Furthermore, the 5 cm thickness of the protective pad 104 effectively protects the bottom of the base plate 101. The surface of the protective pad 104 also has the same number of through slots 102, which effectively facilitates the dissipation and transfer of heat generated during engine operation.

[0026] like Figure 4As shown, side plate structures 2 are fixedly installed on both sides of the base plate structure 1. The side plate structure 2 includes a side plate body 201 with through holes 202. There are two sets of through holes 202, and each set of through holes 202 is symmetrically opened about the surface of the side plate body 201. When there are two sets of four through holes in the structure, the symmetry of the structure is reflected, as well as the through connection and through connection limiting of the structure. Furthermore, when there are two sets of four through holes in the structure, the axial symmetry and aesthetics of the structure are also reflected. The side plate body 201 is welded and fixed to the base plate body 101. The outer surface of the body 201 is also fixed with a protective pad 104. One set of side plates 201 is provided, and the side plates 201 are symmetrically arranged about the axis of the bottom plate 101. When the above-mentioned components are provided in a set of two pieces, it not only reflects the fixation of the above-mentioned components installation, but also reflects the openness of the above-mentioned components installation. Furthermore, when the above-mentioned components are provided in a set of two pieces, it also reflects the symmetry and practicality of the above-mentioned components installation. Moreover, when the side plates 201 are symmetrically arranged about the axis of the bottom plate 101, it reflects the aesthetics and enveloping effect of the symmetrical installation of the above-mentioned components.

[0027] In the above scheme, when the engine of the off-road motorcycle needs to be protected against collisions, the operator holds the base plate 101 and installs the side plates 201 around the sides and bottom of the engine. Then, the operator uses the connecting bolts to quickly install the base plate 101 and the side plates 201 by passing through the through holes 202 and connecting to the middle of the engine. When the off-road motorcycle is in motion, the engine of the off-road motorcycle is protected against collisions by the base plate 101, the side plates 201 and the protective pads 104.
