Description

Technical Field

[0001] The invention relates to the technical field of vibration reduction and noise reduction, and in particular to an intelligent engine case vibration damper. Background Art

[0002] With the development of science and technology and the progress of society, the engine power is increasing and the vehicle speed is increasing, which gradually leads to the emergence of vehicle noise problems. Vehicle noise not only causes environmental pollution, but also affects the driver's concentration and the driving safety of the vehicle, and even causes mental and physical harm to the people in the car. Therefore, more and more car owners hope that the vehicle runs smoothly and the driving environment is quiet. Therefore, the vibration and noise performance of the car engine is particularly important.

[0003] The existing announcement number CN207579573U discloses a vibration damping device for an engine, including an engine mount and a vibration damping block. The vibration damping block is a "T" hollow structure as a whole, and a slot is provided on the top of the vibration damping block. The engine mount arranged vertically is inserted into the slot. The gap between the upper half of the engine mount and the vibration damping block is filled with vibration damping rubber, and a movable block is provided at the lower half of the engine mount. The structure is reasonable and practical. By using a hollow "T"-shaped vibration damping block and a matching spring and vibration damping rubber in the vibration damping block, the engine can achieve a certain degree of vibration damping effect. By arranging the same cylinders at the bottom of both sides of the vibration damping block, the cylinders can produce a certain damping effect and can reduce a large part of the vibration.

[0004] However, the above-mentioned engine vibration reduction device only has a vibration reduction function and fails to convert the vibration force into motion, resulting in energy waste. Summary of the invention

[0005] The purpose of the present invention is to provide an intelligent engine case vibration damper, which solves the problem that the existing engine vibration damping device only has a vibration damping function but fails to convert the vibration force into motion, resulting in energy waste.

[0006] To achieve the above object, the present invention provides an intelligent engine case vibration damper, comprising a vibration damper outer shell, a temperature sensing device and two energy capture devices;

[0007] The two energy-capturing devices are symmetrically arranged on the inner side of the outer shell of the shock absorber. The lower part of the outer shell of the shock absorber has two power exponential control structures. The temperature sensing device is arranged on the inner side of the outer shell of the shock absorber.

[0008] Among them, the energy capture device includes a mass block, a spring and a small ball, one end of the mass block is fixed to one side of the upper inner wall of the shock absorber outer shell, and the other end of the mass block is connected to the spring; the small ball is connected to the spring and is located at the end of the spring away from the mass block.

[0009] Wherein, the energy capture device also includes a metal guide rail, which is fixedly connected to the shock absorber outer shell and is located outside the small ball to constrain the movement of the small ball.

[0010] Among them, the two energy capture devices include four sheet-like permanent magnet blocks, which are respectively fixedly connected to the outer shell of the shock absorber. The four sheet-like permanent magnet blocks are respectively opposite to each other and are respectively located on both sides of the two metal guide rails, and the two sheet-like permanent magnet blocks completely cover the motion range of the ball.

[0011] The temperature sensing device comprises a shell, a diode, a voltage regulator, a battery and a temperature sensor. The shell is arranged on the inner side of the shock absorber outer shell, and the diode, the voltage regulator, the battery and the temperature sensor are respectively located inside the shell.

[0012] The intelligent engine case shock absorber of the present invention gathers vibration energy at the center through the power exponential control structure at the lower part of the shock absorber outer shell, and then transfers the energy to the mass block, which drives the spring and the small ball to move, and the small ball cuts the magnetic lines of force to generate electrical energy to make the temperature sensor work. After the energy of vibration and noise is gathered by the shock absorber outer shell structure, it is converted into electrical energy that can be used to supply the temperature sensor through magnetoelectricity, thereby reducing the vibration and noise of the engine, allowing the driver and passengers to have a smooth, quiet and more comfortable driving experience in the car, and making full use of energy to reduce energy waste.
