[0018] The essential features and advantages of the present invention are further described below with reference to examples, but the present invention is not limited to the examples listed.

[0019] like Figures 1 to 4As shown, an anti-seismic device for an electric actuator of this embodiment, the anti-seismic device 10 is arranged at the bottom of the electric actuator 20. It includes a main body 1, the main body 1 includes a bottom plate 2 and a side wall 3, the side wall 3 is arranged around the bottom plate 2 to form an accommodating cavity 4, and the bottom of the electric actuator 20 can be arranged in the accommodating cavity 4. The bottom plate 2 has a mounting hole 21, and an anti-seismic component 5 is provided in the mounting hole 21. The anti-seismic component 5 can buffer the vibration of the electric actuator 20, and the anti-seismic component is made of elastic material. The anti-seismic component 5 includes a clamping portion 51, and a base 52 arranged below the clamping portion 51, the clamping portion 51 has an annular groove 511, and the annular groove 511 is clamped with the mounting hole 21, so that the anti-seismic component 5 is assembled with the main body 1. The base 52 has an inner wall 521 and an outer wall 522, and between the inner wall 521 and the outer wall 522 is a support portion 523 of the base 52, the width of the support portion 523 gradually increases from top to bottom, and an arc-shaped connecting portion 524 is provided between the support portion 523 and the bottom of the base 52. The middle part of the anti-vibration component 5 has a through hole 53, and the through hole 53 passes through the clamping portion 51 and the base 52 from top to bottom, so as to be conveniently locked on an external device through a locking member. In the above technical solution, when the vibration is transmitted to the anti-vibration component 5, the support portion 523 with a gradually changing width can maintain a certain deformation state under vibrations of different intensities, thereby buffering energy. In addition, the arc-shaped connecting portion can facilitate the deformation of the support portion, avoid cracking at the connection, and extend the service life. Through the above technical solution, vibration energy can be buffered and the impact on the electric actuator can be reduced.

[0020] In this embodiment, a protrusion 512 is provided in the annular groove 511. The protrusion 512 faces the opening of the annular groove 511. Therefore, when friction occurs between the mounting hole 21 and the clamping portion 51, the protrusion 512 can reduce the risk of cracking and damage to the annular groove 511, thereby improving the service life. In this embodiment, the protrusion is arc-shaped. The through hole 53 includes a first hole 531 and a second hole 532 connected to the first hole 531. The first hole 531 is located in the clamping portion 51, and the second hole 532 is located in the base 52. The second hole 532 is surrounded by an inner sidewall 521. The first and second holes of different apertures can facilitate deformation between the clamping portion 51 and the base 52. The inner sidewall 521 is inclined inward from top to bottom, and the outer sidewall 522 is inclined outward from top to bottom, thereby forming a support portion 523.

[0021] In this embodiment, the side walls 3 and bottom plate 2 of the main body 1 are provided with ventilation slots 11. Several ventilation slots 11 are spaced apart to enhance the heat dissipation performance of the main body 1. The side walls 3 are provided with mating holes 31, allowing screws and other fasteners to be connected and secured to the electric actuator. Positioning posts 6 are positioned between adjacent side walls 3, with mounting holes 21 located at their bases. These posts 6 enhance the connection stability between the side walls. There are four positioning posts 6, and the four side walls 3 are arranged in a rectangular shape, facilitating assembly with the electric actuator.

[0022] The anti-vibration device for an electric actuator of this embodiment can facilitate the installation of the electric actuator. It only needs to be installed locally to buffer vibration energy and reduce the impact on the electric actuator and the heat dissipation effect.
