[0001] The invention relates to the field of electromechanical technology, and in particular to a linear motor-controlled balancing module. Background Art

[0002] With the development of science and technology, people have higher and higher demands for the functions and comfort of cars. As we all know, the vibration and noise of the engine at work are very large, which brings a bad experience to the surrounding environment and the drivers and passengers. The vibration and noise of the engine are mainly caused by the reciprocating inertia force generated when the piston moves up and down. The total reciprocating inertia force generated by the different number of engine cylinders is also different. For example, the three-cylinder engine is mainly the first-order reciprocating inertia moment, and the four-cylinder engine is mainly the second-order reciprocating inertia force. Summary of the invention

[0003] The purpose of the present invention is to propose a new type of balancing module, which makes the mass block vibrate up and down to balance the reciprocating inertia force of the piston, thereby improving the vibration and noise of the engine. At the same time, the number and layout of the mass blocks can be increased according to the number of engine cylinders. Compared with the traditional balancing mechanism, the structure is compact, does not require a complex gear set mechanism, and does not require a corresponding phase angle during assembly. It has higher assembly freedom and intelligence.

[0005] Preferably, the casing body is connected to the engine via bolts.

[0006] Preferably, the stator is fixedly connected to the housing body.

[0007] Preferably, the stator is composed of an electromagnetic coil, and the coil generates a magnetic field to drive the mass block when energized.

[0008] Preferably, the mass block can move along the guide rail to form an opposite simple harmonic inertial force to offset the inertial force of the piston.

[0009] Preferably, the guide rail is composed of an iron core and a guide rail, and is used to ensure that the mass block moves along a specific path.

[0010] Preferably, the controller can collect the rotation speed of the engine and the relevant position of the crankshaft and feed back the balancing module to drive the mass block to perform corresponding movement.

[0011] In summary, the present invention includes the following beneficial technical effects:

[0012] The present invention can make the mass block vibrate up and down to balance the reciprocating inertia force of the piston, thereby improving the vibration and noise of the engine. At the same time, the number and layout of the mass blocks can be increased according to the number of engine cylinders. Compared with the traditional balancing mechanism, the structure is compact, does not require a complex gear set mechanism, and does not require a corresponding phase angle during assembly.

[0016] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0017] An embodiment of the present invention discloses a linear motor controlled balancing module, the structure of which mainly includes a shell body 1, a guide rail 4 passing through the middle of the shell body 1, a stator 2 arranged on the inner wall of the shell body 1 and located on both sides of the guide rail 4, a mass block 3 slidably connected to the guide rail 4, and a controller 5 arranged on the outside of the shell body 1.

[0018] The main structure of the balancing module:

[0019] Shell body 1: Shell body 1 is the main base component of the entire module. The shell is the outer boundary of the entire module and is connected to the engine by bolts.

[0020] Stator 2: Stator 2 is the fixed part, usually composed of a series of electromagnetic coils. When powered, these coils will generate a magnetic field to drive the mass 3. Stator 2 is usually fixed to the housing body 1.

[0021] Mass block 3: Mass block 3 is the main component to balance the unbalanced force of the engine. The corresponding up and down movement of mass block 3 forms an opposite simple harmonic inertial force to offset the inertial force of the piston. Mass block 3 needs to interact with the magnetic field of stator 2. Mass block 3 contains permanent magnet 6. Figure 1 The two end structures of the middle mass block 3 close to the stator 2 are the permanent magnets 6 .

[0022] Guide rail 4: The guide rail 4 is a component that ensures the movement trajectory of the mass block 3, and is usually composed of an iron core, a guide rail, etc., and is used to ensure that the mass block 3 moves along a specific path.

[0023] Controller 5: Controller 5 is a control module for receiving engine data and controlling the movement speed of mass block 3. It needs to collect the engine speed and the relevant position of the crankshaft and feed back the balance module to drive mass block 3 to perform corresponding movement. It needs to have high sensitivity and ensure accurate control under high temperature of engine movement.

[0024] The main function of the balancing module:

[0025] Attached Figure 2 It is a phase diagram of the second-order reciprocating inertia force of a four-cylinder engine. When the engine is working, the corresponding piston position will form the corresponding reciprocating inertia force. The controller 5 will read the phase position of the engine rotation and the rotation speed of the crankshaft, and input the relevant signal to the module. Let the mass block 3 vibrate up and down at the same frequency to offset the reciprocating inertia force.

[0026] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
