Description

Technical Field

[0001] This utility model relates to the field of electric motor technology, specifically to an electric motor with an anti-vibration structure. Background Technology

[0002] An electric motor is a device that converts electrical energy into mechanical energy. It consists of a stator (stationary part) and a rotor (rotating part) and works based on the principle of electromagnetic induction. When current flows through the stator windings, it generates a magnetic field, which interacts with the rotor's magnetic field, causing the rotor to rotate and thus output torque to drive the load. Motors can be classified by power source type into DC motors (which switch the current direction via a commutator) and AC motors (such as asynchronous motors and synchronous motors); and by structure into special types such as stepper motors and servo motors.

[0003] For example, according to authorization announcement number CN220210119U, an electric motor with a heat dissipation structure includes an electric motor body, a heat dissipation mechanism connected to the rear side of the electric motor body, and a rear cover and a fan. The rear cover is detachably connected to the rear side of the electric motor body, and an air outlet is provided on the rear side of the rear cover. A filter screen is detachably connected to the rear side of the rear cover, and multiple sets of evenly distributed filter holes are provided on the filter screen. Each filter hole group consists of multiple filter holes arranged in a fan shape. Multiple baffles corresponding to the multiple sets of filter holes are connected to the air outlet of the rear cover. A rotating connecting ring is connected to the front side of the filter screen and is rotatably connected to the rear side of the rear cover. The rotating connecting ring has a first insertion hole group and a second insertion hole group. A plug-in device is connected to the rear cover. In this invention, when the plug-in device is inserted into the first insertion hole group, the air outlet communicates with the filter hole group, so the filter hole can discharge air normally. When the plug-in device is inserted into the second insertion hole group, it has a dustproof effect.

[0004] However, existing motor support frames do not have anti-vibration structures, which cannot provide vibration damping support for the motor during operation. After long-term use, the motor is easily damaged by vibration. Therefore, there is an urgent need in the market to develop a motor with an anti-vibration structure to help people solve the existing problems. Utility Model Content

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Please see Figure 1-4This utility model provides an embodiment of an electric motor with an anti-seismic structure, comprising a support frame 1. Support rods 101 are fixedly connected to both sides of the middle portion of the support frame 1. Limiting posts 2 are fixedly connected to the front and rear ends of the upper ends of the two support rods 101. An electric motor 3 is connected to the upper ends of the four limiting posts 2. Support wing plates 301 are fixedly connected to the front and rear ends of the lower ends of both sides of the electric motor 3. Each support wing plate 301 has a circular through hole 302. The upper ends of the four limiting posts 2 extend through the circular through holes 302 of the four support wing plates 301, protruding from the upper surface of the support wing plates 301 and connected to the limiting posts 2. A rubber washer 203 is provided between the lower end of the positioning plate 202 and the upper end of the support wing plate 301. A butterfly spring 205 is provided on the positioning post 2 at the lower end of the support wing plate 301 and the upper end of the support rod 101. An internal threaded hole 201 is provided in the middle of the surface of the positioning post 2. The positioning plate 202 and the upper end of the positioning post 2 are connected and fixed by the first bolt 204 through the positioning plate 202 and inserted into the internal threaded hole 201. The motor 3 is positioned by connecting the four positioning posts 2 to the four support wing plates 301 respectively, and the four butterfly springs 205 support the four support wing plates 301 respectively.

[0024] Please see Figure 2 and Figure 3The motor 3 has two second rotating seats 303 fixedly connected to the front and rear ends of the middle of both sides of the upper surface of the support frame 1. The four second rotating seats 303 on the motor 3 are respectively connected to the four first rotating seats 102 on the support frame 1 through damping telescopic rods 4. The first rotating seats 102 and the support frame 1 are fixedly connected to the second rotating seats 303 and the motor 3 through second bolts. The damping telescopic rod 4 includes a damping cylinder 5 and a telescopic rod 6. The lower end of the damping cylinder 5 is fixedly connected to a first fixing plate 501. The lower end of the first fixing plate 501 is fixedly connected to a first rotating connector 502. The telescopic rod 6 is provided inside the damping cylinder 5. The upper end of the telescopic rod 6 extends out of the damping cylinder 5 and is fixedly connected to a second fixing plate 601. The upper end of the second fixing plate 601 is fixedly connected to a second rotating connector 602. 502 is inserted into the first rotating seat 102 and rotatably connected through the first rotating shaft 503. The first rotating shaft 503 is fixedly connected to the first rotating connector 502. The second rotating connector 602 is inserted into the second rotating seat 303 and rotatably connected through the second rotating shaft 603. The second rotating shaft 603 is fixedly connected to the second rotating connector 602. A buffer spring 7 is provided on the outside of the damping cylinder 5 and the telescopic rod 6 and between the first fixed plate 501 and the second fixed plate 601. When the motor 3 is in use, the telescopic rod 6 inside the damping cylinder 5 will extend and retract with the swing of the second rotating seat 303. The internal damping medium (such as hydraulic oil or gas) generates resistance and consumes kinetic energy, while the external buffer spring 7 provides additional buffering through compression / rebound. The rotation design of the first rotating shaft 503 and the second rotating shaft 603 allows the damping telescopic rod 4 to be adjusted adaptively at multiple angles, ensuring that the vibration energy is decomposed in multiple directions.

[0025] Working Principle: During operation, the vibration generated by the motor is transmitted to the support wing plate 301. At this time, four butterfly springs 205 absorb the vertical vibration energy through elastic deformation, while rubber gaskets 203 provide flexible buffering and suppress high-frequency micro-amplitude vibrations. Horizontal vibrations are dissipated through four sets of damping telescopic rods 4. When the telescopic rod 6 reciprocates within the damping cylinder 5, the viscous resistance generated by the internal damping medium converts kinetic energy into heat energy, while the external buffer springs 7 further attenuate the vibration amplitude through compression and rebound. The omnidirectional rotation design of the first rotating shaft 503 and the second rotating shaft 603 allows the damping telescopic rods 4 to adapt to the multi-angle displacement changes of the motor, ensuring that the vibration force is decomposed in multiple dimensions. This structure forms a three-dimensional anti-vibration system through the vertical damping of the butterfly springs 205, the horizontal energy dissipation of the damping telescopic rods 4, and the local buffering of the rubber gaskets 203, effectively reducing the vibration transmission of the motor 3 and extending the service life of the equipment.
