[0002] An engine is a device that converts the chemical energy of fuel into mechanical energy and is widely used in various vehicles and mechanical equipment. The working principle of an engine is based on the basic principles of thermodynamics and kinetics. It generates high-temperature and high-pressure gas by burning fuel, which pushes the piston to reciprocate in the cylinder, thereby driving the crankshaft to rotate and output power.
[0003] The engine pulley is a key component in the engine system. It is connected to the engine's crankshaft through a belt and is used to drive the engine's auxiliary equipment, such as the generator, water pump, air-conditioning compressor, etc. The design and function of the pulley are crucial to the normal operation of the engine.
[0004] However, the existing engine pulley is directly exposed inside the engine. When the pulley or belt breaks accidentally, the internal structure of the engine will be damaged. After the belt breaks, the flying belt fragments may hit other components inside the engine, such as the crankshaft, flywheel, water pump, generator, etc., causing these components to be damaged or deformed. Therefore, a new solution is needed to solve this problem. Utility Model Content

DETAILED DESCRIPTION
[0023] The following will disclose multiple embodiments of the utility model with diagrams. For the purpose of clear description, many physical details will be described together in the following description. However, it should be understood that these physical details should not be used to limit the utility model. In other words, in some embodiments of the utility model, these physical details are not necessary. In addition, for the purpose of simplifying the diagram, some conventional structures and components will be depicted in a simple schematic manner in the diagram.
[0024] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 The utility model discloses an engine pulley anti-collision device, comprising an engine protective shell 1, which can prevent dust, water, oil and other pollutants from entering the interior of the engine. The left side of the engine protective shell 1 is rotatably connected to a rotating shaft 20, and the left side of the rotating shaft 20 is fixedly connected to a gear 16.
[0025] The outer surface of gear 16 is connected to a transmission belt 8, which connects gear 16 and other parts of the engine such as a water pump, a generator, etc., to transmit power from the crankshaft of the engine to these auxiliary equipment to ensure that they can work normally. The inner wall of the transmission belt 8 is connected to gear 2 7. Through the combination of gear 1 16, gear 2 7 and transmission belt 8, power distribution and transmission can be achieved, so that multiple parts of the engine can obtain power simultaneously or separately.
[0026] Two alloy buffer rings 10 are fixedly connected to the inner walls of gear 16 and gear 2 7. The use of alloy buffer rings 10 can absorb and reduce the impact and vibration generated by gear 16 and gear 2 7 during operation, and protect gear 16, gear 2 7 and transmission belt 8 from damage. The inner wall of each gear 16 is fixedly connected to a rubber pad 15. The use of rubber pads 15 can improve the wear resistance between gear 1 16, gear 2 7 and inner hub 11, reduce wear, and extend the service life of gear 1 16 and gear 2 7. The alloy buffer rings 10 are located at the front and rear ends of the rubber pad 15.
[0027] A transmission belt limiting wheel 19 is fixedly connected to the left side of the gear 16. The function of the transmission belt limiting wheel 19 is to limit the position of the transmission belt 8 in the engine to ensure that the transmission belt 8 does not deviate from the predetermined path during operation to prevent slipping or tooth jumping. The inner wall of each rubber pad 15 is fixedly connected to the inner hub 11. The design of the inner hub 11 can improve the carrying capacity of the gear 16 and ensure stable operation under high load. The inner wall of each inner hub 11 is fixedly connected to a reinforcing rib 12. The use of the reinforcing rib 12 can enhance the structural strength of the inner hub 11 and improve its ability to resist bending and torsion, especially under high load or high-speed operation.
[0028] like Figure 2 , Figure 4 As shown, the inner wall of the engine protection shell 1 is fixedly connected with the engine cylinder block 2, and the engine protection shell 1 can absorb and reduce the noise and vibration generated when the engine cylinder block 2 is running, thereby improving the ride comfort of the vehicle. The left side of the motor 5 is rotatably connected with the rotating shaft 2 4, and the inner wall of the reinforcing rib 12 is fixedly connected with a fixing ring 13, which can fix the rotating shaft 2 4 and the rotating shaft 1 20 to ensure their correct position and stability in the engine compartment. The inner wall of the fixing ring 13 is provided with a snap-in groove 14, and the design of the snap-in groove 14 can make the rotating shaft 2 4 and the rotating shaft 1 20 more convenient to install.
[0029] like Figure 1 , Figure 5 As shown, a pulley protection cover 3 is provided on the left side of the engine protection shell 1. The pulley protection cover 3 is designed to cover and protect the engine pulley, prevent external pollution and damage, and improve the reliability and life of the pulley. The inner wall of the pulley protection cover 3 is provided with a buffer pad 9. The use of the buffer pad 9 can absorb and reduce the impact and vibration of the pulley during operation, and protect the pulley from damage.
[0030] A cavity 18 is opened inside the buffer pad 9, and the cavity 18 can serve as a buffer space to absorb and disperse the energy transmitted to the buffer pad 9 by external impact or vibration, thereby reducing the direct impact on the pulley. A buffer air cushion 17 is fixedly connected to the inner wall of the cavity 18. The buffer air cushion 17 inside the cavity 18 can further absorb the impact force, thereby improving the protective effect of the pulley protection cover 3 on the pulley and reducing the risk of damage to the internal structure of the engine when the transmission belt 8 breaks or in abnormal circumstances.
[0031] The front of the engine protection shell 1 is fixedly connected to a base 6, which is designed to support the motor 5 to ensure its stability and correct position in the engine compartment. The base 6 is usually made of a strong material, such as metal or high-strength plastic, to withstand the weight of the engine and vibration during operation. The front of the base 6 is provided with a motor 5, which is arranged on the front of the base 6 to provide power.
[0032] The above description is only an embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the scope of the claims of the present invention.
