[0020] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0021] Please refer to Figures 1-4, A compact electric actuator with good heat dissipation performance, comprising a driving component, a supporting component and a protective component. The supporting component includes an L-shaped bracket 1 and legs 2. The legs 2 are arranged at the four corners of the bottom wall of the bracket 1. The driving component includes a fixed seat 3, a motor 4, a screw rod 5, a wiring seat 6, a slider 7 and a linear table 8. The fixed seat 3 is arranged on the side wall of the bracket 1. The output end of the motor 4 penetrates through the fixed seat 3 and the side wall of the bracket 1 and is connected to the screw rod 5. A linear table 8 is slidably arranged on the bracket 1. The screw rod 5 threadedly connected to the slider 7 is further arranged below the linear table 8. A heat dissipation and protection component and a wiring seat 6 are further arranged at one end of the fixed seat 3 away from the bracket 1. The protective component includes a protective cover 9, a heat dissipation fan 10 and an auxiliary component. The protective cover 9 covers the motor 4 and the wiring seat 6. An opening is arranged at one end of the protective cover 9. An auxiliary component for reducing the opening area of the opening is arranged on the protective cover 9. The heat dissipation fan 10 is embedded at the other end of the protective cover 9.

[0022] During the actual use process, the protective cover 9 covers the fixed seat 3, which is used to support the auxiliary component and the heat dissipation fan 10. After the wiring seat 6 is wired, the motor 4 drives the screw rod 5 to rotate, the heat dissipation fan 10 rotates, heat is generated by the drive of the motor 4 and discharged through the heat dissipation fan 10. The protective cover 9 is also arranged on the heat dissipation fan 10 to prevent accidental contact by hands. The slider 7 drives the linear table 8 to move on the bracket 1, and the legs 2 provide stable support for the bracket 1.

[0023] During the actual use process, when wiring, the auxiliary component includes an elastic component, a flap 11 and a closing plate 12. An elastic component is arranged inside the protective cover 9. The closing plate 12 is slidably connected to the opening. The flap 11 connected to the elastic component is further arranged on the closing plate 12. The elastic component includes a spring 13 and a telescopic rod 14. The spring 13 is sleeved on the telescopic rod 14. Both ends of the spring 13 and the telescopic rod 14 are respectively connected to the protective cover 9 and the flap 11. An unlocking plate 15 protruding from the opening is further arranged on the closing plate 12. A connection hole is further arranged at one end of the closing plate 12 close to the wiring seat 6. Initially, the elastic component is in a natural elongation state. At this time, only the connection hole is exposed from the opening. By pushing the closing plate 12 through the unlocking plate 15, the flap 11 of the closing plate 12 squeezes the spring 13, and the telescopic rod 14 contracts. At this time, the opening becomes larger, and the wiring head can be inserted into the wiring seat 6. Then, the unlocking plate 15 is no longer pushed, and the elastic component resets, and the cable is discharged from the connection hole.

[0024] In this embodiment, the bottom walls of the legs 2, the fixed seat 3 and the protective cover 9 are flush, ensuring the stability of their support.

[0025] The motor 4 adopts a servo motor with stable operation and precise control.
