[0033] It should be noted that the battery assembly 5 is an existing storage battery assembly 5, and its specific structure and working principle are all existing technologies, which will not be described in detail here.

[0034] like Figures 1 to 9 As shown, further, the housing 1 is provided with a front cover 13 and a rear cover 14 at the openings on both sides of the motor mounting tube 11, the hoisting mechanism 3 is connected to the front cover 13, and a lifting ring 15 is provided at the bottom of the front cover 13; the rear cover 14 is provided with a first buckle assembly 16, the first buckle assembly 16 is buckled and connected to one end of the battery assembly 5, and a main control module 6 electrically connected to the battery assembly 5 is provided in the rear cover 14. By respectively providing the front cover 13 and the rear cover 14 at the openings on both sides of the motor mounting tube 11, the overall stability of the housing 1 is effectively enhanced. The connection design of the hoisting mechanism 3 and the front cover 13 not only facilitates the installation and debugging of the hoisting mechanism 3, but also provides the user with a hoisting connection position through the lifting ring 15 at the bottom of the front cover 13, thereby enhancing the flexibility of use.

The rope separation grooves provided inside the rope separation seat 31 and the rope separation guide wheels 35 on both sides can provide a strong guarantee for the smooth separation and guidance of the ropes, effectively preventing the entanglement and confusion between the ropes, and the rope separation block 32 is located between the two rope separation guide wheels 35, and its position and shape can better match the movement trajectory of the ropes, further enhance the separation effect of the ropes, and avoid the problem of the ropes being intertwined and entangled in the winch disc 33. As a core transmission component, the winch disc 33 is tightly connected to the first output end of the motor assembly 2 to ensure efficient power transmission, and the layout of the winch disc 33 below the rope separation block 32 allows the rope to smoothly enter and be wound around the winch disc 33 during the winching process, thereby realizing the rope retraction and release operation, and the bottom of the winch cover 34 is hinged to the front cover 13, so that the winch cover 34 can be flexibly opened or closed when needed, which is convenient for maintenance and inspection of the winch disc 33. At the same time, the top of the winch cover 34 is connected to the buckle of the rope splitting seat 31 through the second buckle assembly 36, which can facilitate the user to open or close the winch cover 34 and reduce the difficulty of opening and closing the winch cover 34.

[0038] like Figures 1 to 9As shown, further, a speed control handle 7 is arranged between the front cover 13 and the rear cover 14, and the speed control handle 7 is located on one side of the casing 1, and a potential unit 71 electrically connected to the speed control handle 7 is arranged in the rear cover 14; a screen unit 8 and an emergency switch unit 9 are respectively arranged on the front cover 13, and a protective plate is arranged on the outer side of the screen unit 8; the screen unit 8, the emergency switch unit 9 and the potential unit 71 are respectively electrically connected to the battery assembly 5 and the main control module 6.

[0039] like Figures 1 to 9 As shown, further, a heat dissipation cavity 17 is provided on one side of the motor mounting tube 11 in the casing 1, and a discharge component 10 is provided in the heat dissipation cavity 17, and the discharge component 10 is electrically connected to the motor component 2; when the device is descending, the motor component 2 reverses to supply reverse power, but since the motor component 2 has a large power, the battery component 5 cannot absorb all of the reverse electric energy, and this excess reverse electric energy needs to be absorbed by the discharge component 10, and the electromotive force is released by heat release; a heat dissipation cavity 17 is provided on one side of the motor mounting tube 11 in the casing 1, and the heat dissipation cavity 17 can be used to quickly guide and dissipate the heat generated by the discharge component 10 to ensure the stable operation and safety of the motor component 2.

[0040] It should be noted that the discharge component 10 may be an existing discharge resistor, and its specific structure and working principle are all existing technologies and will not be described in detail here.

[0042] For ease of understanding, the working principle of the electromagnetic brake unit 41 is specifically described by the following example: when the motor assembly 2 is powered on, the direct current of the coil of the motor assembly 2 generates suction to separate the two friction surfaces at the tail of the electromagnetic brake unit 41, that is, the repulsive force causes the friction surfaces to open, thereby releasing the second output end and allowing the motor assembly 2 to rotate freely. If the motor assembly 2 is powered off, the electromagnetic brake unit 41 will cause the two friction surfaces to clamp the second output end under the action of the spring, thereby braking the second output end, that is, braking the motor assembly 2.

[0043] like Figures 1 to 9 As shown, further, the top of the front cover 13 is provided with a slide groove 131 opening upward, a limit block 132 is provided in the slide groove 131, at least one guide slide is provided on one side of the slide groove 131, a guide groove connected with the guide slide is provided on the limit block 132, and an in-place detection unit 133 electrically connected to the main control module 6 is provided at the bottom of the slide groove 131, and the trigger end of the in-place detection unit 133 is located at the bottom of the limit block 132; the limit block 132 is closely matched with the guide slide through the guide groove, so as to realize a stable and smooth sliding action. In addition, an in-place detection unit 133 electrically connected to the main control module 6 is also provided at the bottom of the slide groove 131, and the sliding position of the limit block 132 is monitored in real time through its trigger end. Once the predetermined position is reached, the corresponding electrical signal can be immediately triggered to be fed back to the main control module 6, thereby realizing the precise control and detection of the winch position.

[0044] It should be noted that the in-position detection unit 133 may be an existing in-position sensor, infrared sensor or other existing sensor with a position detection function.

Secondly, the power base 54 can facilitate the connection between the battery assembly 5 and the motor assembly 2 and the main control module 6, and the power connector 56 can easily establish an electrical connection with the battery part 53 to ensure the stable transmission of current. In addition, the battery assembly 5 is connected to the housing 1 and the back cover 14 by means of sliding connection and buckle locking. The sliding connection method can facilitate the disassembly and assembly of the battery assembly 5 from the battery installation slot 12. The cooperation of the battery lock buckle with the first sliding lock slot, the slide plate and the first spring portion further enhances the stability of the battery assembly 5 and realizes the detachable connection between the battery assembly 5 and the battery installation slot 12. When the battery lock buckle is connected with the first buckle slot 57, the battery assembly 5 is firmly locked in the battery installation slot 12, effectively preventing it from falling off or being damaged due to accidental collision or vibration. The groove 58 set at the bottom of the battery lower shell 52 can facilitate the user to pull the battery assembly 5 out of the battery installation slot 12, thereby improving the user's experience.
