Description

Technical Field

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

[0002] With technological advancements, people's demands for greater functionality and comfort in their vehicles are increasing. It's well known that operating engines generate significant vibration and noise, creating a negative experience for both the surrounding environment and the driver and passengers. Engine vibration and noise are primarily caused by the reciprocating inertial force generated by the piston's upward and downward movement. The total reciprocating inertial force varies depending on the number of cylinders in the engine. For example, a three-cylinder engine primarily experiences first-order reciprocating inertia, while a four-cylinder engine primarily experiences second-order reciprocating inertia. Utility Model Content

Furthermore, the number and layout of the masses can be increased to accommodate the number of engine cylinders. Compared to traditional balancing mechanisms, this design offers a more compact structure, eliminates the need for complex gear trains, and eliminates the need for phase angle adjustments during assembly. This provides greater assembly flexibility and intelligence.

[0005] Preferably, the housing 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, which 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 engine speed and the relevant position of the crankshaft and feed back to the balancing module to drive the mass block to perform corresponding movement.

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

[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 embodiments described 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 making creative efforts are within the scope of protection of the present invention.

[0017] An embodiment of the present utility model 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 slidingly 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: The stator 2 is the stationary part, typically consisting of a series of electromagnetic coils. When energized, these coils generate a magnetic field that drives the mass 3. The stator 2 is typically fixed to the housing 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 structures at both ends of the middle mass block 3 close to the stator 2 are permanent magnets 6 .

[0022] Guide rail 4: The guide rail 4 is a component that ensures the motion trajectory of the mass block 3. It 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: This module receives engine data and controls the speed of mass 3. It collects engine speed and crankshaft position and provides feedback to the balancing module, driving mass 3 to move accordingly. It requires high sensitivity and accurate control even under the high temperatures of the engine.

[0024] The main function of the balancing module:

[0025] Attachment Figure 2 This is a phase diagram of the second-order reciprocating inertial force of a four-cylinder engine. When the engine is operating, the corresponding piston position generates a corresponding reciprocating inertial force. Controller 5 reads the engine rotation phase position and crankshaft rotation speed and inputs the relevant signals to the module. Mass 3 is then vibrated up and down at the same frequency to offset the reciprocating inertial 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, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
