Description

Technical Field

[0001] This utility model relates to the field of all-terrain vehicle technology, specifically an all-terrain vehicle engine buffer device. Background Technology

[0002] All-terrain vehicles (ATVs) are vehicles capable of traversing any terrain, moving freely on surfaces where ordinary vehicles struggle. The engine of an ATV is typically rigidly connected to the chassis frame; specifically, the engine and chassis are directly connected via a fixing device without any elastic elements or other buffer mechanisms. While this connection method offers advantages such as simple structure and easy installation, it lacks effective cushioning between the engine and chassis during operation, negatively impacting both the engine and the entire vehicle.

[0003] The impact of rigid connections on the engine is mainly in three aspects: First, vibration and shock: All-terrain vehicles typically travel on complex terrains, such as sand, muddy roads, or rugged mountain roads. Rigid connections cause the engine to directly bear the impact and vibration from the ground. These impact forces are transmitted to internal engine components, such as the crankshaft, connecting rods, and cylinder block, which may lead to fatigue damage to these components. Second, resonance: Due to the lack of buffering, the engine may resonate with the vehicle frame during operation. Resonance will aggravate the engine's vibration amplitude, further affecting the engine's performance and lifespan. Third, high installation precision requirements: Rigid connections require high precision in the installation of the engine and the vehicle frame. If the installation position is inaccurate, it may lead to imbalance during engine operation, thereby affecting its performance and lifespan.

[0004] Therefore, in order to solve the problems caused by rigid connections, the engine of an all-terrain vehicle needs to be installed with a buffer design. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the defects of the prior art and provide an engine buffer device for all-terrain vehicles.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0007] An all-terrain vehicle engine buffer device includes four mounting seats. The bottom of the mounting seats is fixedly connected to the vehicle body bracket. A connecting shaft is connected between two mounting seats. Two mounting plates are fixedly connected to the connecting shaft. The two mounting plates are respectively fixedly connected to two sides of the engine by bolts. The mounting plates have a V-shaped structure and are sheet metal parts.

[0008] The other two mounting seats are connected to a first assembly shaft, which passes through a through hole in the engine, and the two mounting seats are located at both ends of the engine through hole.

[0009] The mounting plate has a buffer opening at the bottom of its V-shaped structure.

[0010] The mounting plate has bent plates at the lower part of the two sides of its V-shaped structure, and the bent plates are attached to the lower part of the engine.

[0011] The mounting base includes a base body, and a through hole is provided in the middle of the base body;

[0012] Two mounting bases near the connecting shaft have a second assembly shaft connected through their through holes. The second assembly shaft passes through the connecting shaft and is a long bolt rod. One end of the second assembly shaft is provided with an external thread and connected to a nut. The nut is locked onto the surface of the mounting base.

[0013] The first assembly shaft is a long bolt rod with an external thread at one end and a nut connected to it. The nut is locked onto the surface of the mounting base.

[0014] The mounting base has fastening bolts at both ends of its bottom, which are used to fix the base to the base plate of the vehicle body bracket.

[0015] The beneficial effects achieved by this utility model are:

[0016] This invention achieves elastic support for the engine by setting up a mounting plate and mounting base, effectively avoiding damage to the engine from rigid loads and impacts. Specifically, the engine and mounting base adopt an elastic connection structure, which can absorb and buffer vibrations and impacts during engine operation, thereby significantly reducing the mechanical stress of the engine and extending its service life. In addition, this elastic support structure can also effectively isolate vibration transmission between the engine and the vehicle frame, improve the overall NVH (noise, vibration, and harshness) performance of the vehicle, and further improve driving comfort.

[0017] Through this design, this utility model not only solves the potential damage to the engine caused by the traditional rigid support method, but also provides a reliable guarantee for the stable operation of the engine. At the same time, it optimizes the layout of the vehicle's power system and lays a technical foundation for the comprehensive improvement of vehicle performance. Attached Figure Description

[0024] Example:

[0025] like Figures 1-3 As shown, an all-terrain vehicle engine buffer device is used to mount the engine 2 on the vehicle body support 1 of the all-terrain vehicle.

[0026] The all-terrain vehicle engine buffer device specifically includes four mounting seats 3. The bottom of the mounting seats 3 is fixedly connected to the vehicle body bracket 1. A connecting shaft 6 is connected between two mounting seats 3. Two mounting plates 4 are welded on the connecting shaft 6. The two mounting plates 4 are fixedly connected to the two sides of the engine 2 by bolts. The mounting plates 4 have a V-shaped structure and are sheet metal parts.

[0027] The aforementioned elastic connection structure can absorb and buffer vibration and impact during engine 2 operation, thereby significantly reducing the mechanical stress of engine 2 and extending its service life.

[0028] The other two mounting seats 3 are connected to a first assembly shaft 7, which passes through the through hole on the engine 2, and the two mounting seats 3 are located at both ends of the through hole on the engine 2.

[0029] Four mounting bases 3 are distributed at the four corners of the bottom of the engine 2 to support the engine 2.

[0030] The bottom of the V-shaped structure of the mounting plate 4 is provided with a buffer opening 8, and the gap at the buffer opening 8 can buffer the rigid impact generated by the vibration of the engine 2. The lower part of the two edges of the V-shaped structure of the mounting plate 4 is provided with a bent plate 9, which fits against the lower part of the engine 2 to further support and protect the engine 2.

[0031] The mounting base 3 includes a base body, and a through hole is provided in the middle of the base body.

[0032] Two mounting seats 3 near the connecting shaft 6 have a second assembly shaft 11 connected through their through holes. The second assembly shaft 11 passes through the connecting shaft 6 and is a long bolt rod. One end of the second assembly shaft 11 is provided with an external thread and connected to a nut. The nut is locked onto the surface of the mounting seat 3. Specifically, the second assembly shaft 11 passes through the through hole of one mounting seat 3, the middle hole of the connecting shaft 6 and the through hole of the other mounting seat 3 in sequence, and is then screwed onto the nut thread.

[0033] The first assembly shaft 7 is a long bolt rod. The first assembly shaft 7 passes through the through holes of its corresponding two mounting seats 3. One end of the first assembly shaft 7 is provided with an external thread and connected to a nut. The nut is locked onto the surface of the mounting seat 3. Specifically, the first assembly shaft 7 passes through the through hole of one mounting seat 3, the through hole of the engine 2 and the through hole of the other mounting seat 3 in sequence, and is then screwed onto the nut thread.

[0034] The mounting base 3 has fastening bolts 5 at both ends of its base. The fastening bolts 5 are used to fix the base to the base plate 10 of the vehicle body bracket 1.

[0035] Specifically, a base plate 10 is connected to the vehicle body bracket 1. The base plate 10 is horizontally set, and the two ends of the seat are set on the upper part of the base plate 10. The fastening bolts 5 pass vertically through the lower part of the base plate 10 and are threadedly connected to the threaded holes at the bottom of the two ends of the seat, thereby realizing the connection between the mounting seat 3 and the vehicle body bracket 1.
