Therefore, a high-voltage electric winch needs to be designed to overcome these difficulties. Summary of the Invention

[0008] Preferably, the overload protector has a protection time of 0.3 seconds.

[0009] The relays inside the controller housing can control the two directions of the drive motor, and the overload protector is used to cut off the overall circuit to prevent damage to the drive motor during use; the high-voltage connector can be directly connected to high-voltage DC power, making the use of the drive motor safer and more reliable.

[0010] Preferably, the reducer assembly includes a reducer housing, an internal gear ring, a first-stage sun gear, a first-stage planetary gear, a second-stage planetary gear, and a third-stage planetary gear; the brake assembly includes a brake seat, a brake nut, and a second-stage sun gear. The internal gear ring is installed inside the reducer housing. The reducer housing is provided with a third-stage planetary carrier assembly. A first-stage sun gear is installed between the third-stage planetary carrier assembly and the bottom of the reducer housing. A second-stage sun gear is installed inside the brake seat. A brake nut is threaded onto the second-stage sun gear. A ratchet is installed between the second-stage sun gear and the brake nut. The ratchet rotates synchronously with the second-stage sun gear. The second-stage sun gear is sleeved on the first-stage... The sun gear has an outer layer, with a gap between the second-stage sun gear and the first-stage sun gear; the brake nut has several first-stage planetary gears rotatably connected to it, and the first-stage planetary gears mesh with the internal teeth of the reducer housing; the external teeth of the brake seat are engaged with the internal teeth of the reducer housing; a second-stage planetary carrier assembly is provided between the third-stage planetary carrier assembly and the brake seat, and the second-stage planetary carrier assembly has several second-stage planetary gears rotatably connected to it, and the second-stage planetary gears synchronously mesh with the internal gear ring and the second-stage sun gear; the third-stage planetary carrier assembly has several third-stage planetary gears rotatably connected to it, and the third-stage planetary gears synchronously mesh with the internal gear ring and the external teeth of the second-stage planetary carrier assembly.

[0014] When the drive motor is working, it drives the first-stage sun gear to rotate via a hexagonal transmission rod. The rotation of the first-stage sun gear drives the second-stage sun gear to rotate. At this time, the second-stage sun gear drives the ratchet to rotate, and the pawl does not jam the ratchet, allowing the second-stage sun gear to rotate normally. The rotation of the second-stage sun gear drives the third-stage planetary gears to rotate, and the third-stage planetary carrier assembly rotates synchronously. The third-stage planetary carrier assembly connects to the roller, allowing the roller to rotate relative to the main support. When braking is required, the drive motor immediately stops rotating, and the first-stage sun gear also immediately stops rotating. However, the second-stage sun gear continues to rotate due to inertia, thus rotating in the opposite direction to the first-stage sun gear. The pawl then locks the ratchet, preventing the first-stage sun gear from continuing to rotate. This keeps the roller in a locked state, preventing slippage or reverse rotation, and thus preventing the heavy object from falling.

The drive motor and control components of the present invention are applicable to high voltage DC power conditions and have good versatility; 2. The control components are equipped with overload protectors, making them safe and reliable to use; 3.

However, the second-stage sun gear 63 continues to rotate due to inertia, thus rotating in the opposite direction to the first-stage sun gear 23. The pawl 66 then locks the ratchet 64, preventing the first-stage sun gear 23 from continuing to rotate. In this way, the roller 4 is in a locked state, preventing slippage or reverse rotation, thus preventing the heavy object from falling.
