Description

Technical Field

[0001] This utility model relates to the field of motor controller technology, specifically to a vibration damping structure for a motor controller. Background Technology

[0002] An electric motor is an electrical device used to convert electrical energy into kinetic energy. Its main working principle is to realize the conversion or transmission of electrical energy through the law of electromagnetic induction. The motor is installed inside various electrical appliances, and the motor's drive shaft is connected to the inside of the appliance, so that the motor can continuously drive the rotating parts inside the appliance to rotate, thereby realizing the transmission of kinetic energy.

[0003] An electric motor, also known as a motor, is a device that converts electrical energy into mechanical energy. It achieves energy conversion based on the law of electromagnetic induction and is widely used in various fields such as industry, commerce, and households. The working principle of an electric motor is based on electromagnetic induction, that is, when a conductor moves in a magnetic field or the magnetic field changes, a current is generated in the conductor. However, the motor controller designed in the present is usually directly connected to the motor and installed together. This configuration means that the vibration generated by the motor during operation is directly transmitted to the controller. In extreme cases, this vibration may cause damage to the controller, thereby affecting the stability and performance of the entire system. Utility Model Content

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-4 This utility model provides a technical solution: a vibration damping structure for a motor controller, including a base 1. Two guide rods 14 are internally connected to the base 1. A spring A15 is sleeved on the outside of each guide rod 14. A connecting block A16 is connected to the far end of each spring A15. Each connecting block 16 is sleeved on the outside of the guide rod 14. A fixing block A17 is connected above each connecting block 16. A movable rod 18 is hinged to the inside of each fixing block A17 via a pin. A fixing block B19 is hinged to the top of each movable rod 18 via a pin. A support plate 5 is connected to the top of multiple fixing blocks B19. The guide rods 14 and springs A15 inside the base 1, in conjunction with the connecting blocks A16 and fixing blocks A17, enhance the stability of the entire structure and absorb and reduce vibrations generated by the motor, protecting the controller body 8 and preventing damage to the controller body 8 due to excessive vibration. Furthermore, the fixing blocks A17, B19, and support plate 5, in conjunction with the springs A15, effectively... The pressure and load during motor operation are distributed, improving the durability and service life of the structure, while also optimizing space utilization. Multiple support blocks A13 are internally connected to the base 1, each with a slot 9 on its top. Through the support blocks A13, in conjunction with the springs B11 and dampers 10 inside, a buffering effect is provided for the movable cover 2. Each slot 9 is internally connected to a spring B11 and a damper 10, with each spring B11 fitted over the damper 10. Each spring B11 and damper 10 has a support block B12 connected to its top. The spring B11 and damper 10 work together to prevent the movable cover 2 from colliding with the base 1 due to vibration, thus preventing damage to the movable cover 2. The movable cover 2 is located on the top of the base 1, and multiple support blocks B12 are connected to the inner wall of the movable cover 2. The support blocks B12 work together with support block A13 to protect the movable cover 2.

[0022] Multiple anti-collision pads 6 are connected to the top of the base 1. These pads are located below the movable cover 2. Each anti-collision pad 6 is made of rubber. The rubber anti-collision pads 6 are installed above the base 1, effectively protecting the base 1 from damage caused by collisions between the base 1 and the movable cover 2. Two mounting slots 3 are provided on the side of the base 1 and the movable cover 2 that are close to each other. One of the mounting slots 3 is connected to a limit rod 7. The limit rod 7 limits the movement of the movable cover 2 during vibration, preventing it from shifting. Each mounting slot 3 is connected to a limit block 4. The end of each limit rod 7 near the movable cover 2 passes through the limit block 4 and the movable cover 2 and extends into the interior of the movable cover 2. The limit block 4 limits the limit rod 7, preventing it from shifting.

[0023] The controller body 8 is placed on top of the support plate 5. The controller body 8 is located below the movable cover 2. By setting the controller body 8, the controller body 8 located below the movable cover 2 is prevented from being damaged by collisions caused by falling objects from above.

[0024] Working principle: In use, the operator places the controller body 8 on the support plate 5 and installs the device in a suitable position. Then, the motor is started. The vibration generated by the motor is transmitted to the controller body 8. The support plate 5, which is in contact with the bottom of the controller body 8, vibrates. The vibrating support plate 5 transmits the force to the spring A15 through the hinge of the movable rod 18. The elastic properties of the spring A15, together with the guide rod 14, allow the spring A15 to absorb the vibration through elastic deformation, thereby reducing the impact on other components and reducing the vibration force on the controller body 8, thus protecting the controller body 8.

[0025] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
