Description

Technical Field

[0001] This utility model relates to the field of electric actuator technology, specifically a heat-dissipating dual electric actuator. Background Technology

[0002] The broadest definition of an actuator is: a drive device capable of providing linear or rotary motion. It utilizes a driving energy source and operates under the influence of a control signal. Actuators use liquid, gas, electricity, or other energy sources and convert them into driving force through a motor, cylinder, or other device. The basic types include partial-turn, multi-turn, and linear drive mechanisms. Existing patent CN116526787A discloses an electrically controlled actuator, comprising: a drive unit disposed within an installation space formed by a lower housing and a partition; the drive unit having a motor output shaft, a circuit board, and a buffer; the buffer is connected to the motor output shaft and positioned between the circuit board and the partition; the drive unit also includes a motor wire frame and a housing fitted over the motor wire frame; the motor wire frame has a winding component and a fixing device. This invention addresses the technical problem of inconvenient winding of enameled wire on the motor wire frame structure of an electrically controlled actuator, thereby improving the winding efficiency of the motor wire frame.

[0003] Regarding the aforementioned technologies, the inventors believe that the following defects exist: In practical applications, the electric actuator generates heat during operation, thus requiring heat dissipation. However, during the heat dissipation process, dust inevitably enters the actuator's interior, affecting its normal operation. Therefore, we propose a heat dissipation dual electric actuator to solve the aforementioned problems. Utility Model Content

The support and protection assembly 3 can be used to position the actuator during use and also to protect it from collision damage during use, thereby improving the service life of the actuator.

[0030] See Figure 4 The mesh plate 206 has a rod hole for the rotating rod 203 to pass through, and the inner wall of the rod hole is rotatably connected to the surface of the rotating rod 203. The rod hole facilitates the rotation of the rotating rod 203 during use, thereby avoiding interference with the rotation of the rotating rod 203.

[0031] See Figure 4 The upper surface of the buffer ring 205 is provided with an annular groove, and a buffer spring 208 is fixedly installed on the inner bottom wall of the annular groove. A protective ring 210 is fixedly installed on the top of the buffer spring 208. The top of the protective ring 210 is fixedly connected to the bottom of the mesh plate 206.

[0032] See Figure 4 A discharge hole is provided on one side of the vertical tube 200. The inner bottom wall of the discharge hole is flush with the top of the buffer ring 205, and the inner top wall of the discharge hole is flush with the top of the mesh plate 206.

[0036] During operation, the actuator is fixed by the support plate 305, and the return spring and damping rod 302 reset it, thus protecting the actuator from damage during use and improving its ease of use. At the same time, the motor 202 is controlled to work, which drives the fan blade 204 and scraper 207 on the rotating rod 203 to rotate. When the fan blade 204 rotates, it blows air into the actuator body 1. The outside air is filtered by the mesh plate 206, and the dust remains on the surface of the mesh plate 206. The scraper 207 can scrape the dust on the mesh plate 206 during rotation. Then the dust is discharged through the discharge port, thus realizing the dust removal operation of the mesh plate 206 during heat dissipation.
