The first end of the power wire 26 is located inside the box body 21, and the second end of the power wire 26 extends to the outside of the box body 21 for connecting to a power source.

[0044] In some examples, such as Figure 1-Figure 4 As shown, the extended display assembly 3 is one, and the control box 2 includes an extended wiring 22, a first end of the extended wiring 22 is located in the box body 21, and a second end 221 of the extended wiring 22 extends outside the box body 21 and is suitable for being detachably connected to the extended display assembly 3.

[0045] Optionally, there are multiple extended display components 3, and the control box 2 may include multiple extended wirings 22, and the multiple extended wirings 22 are connected to the extended display components 3 in a one-to-one correspondence.

[0046] exist Figure 1 In the illustrated embodiment, the extended display assembly 3 includes a light board 31 and an extended extension line 32, wherein the light board 31 includes a plurality of first display lights 311 for displaying the load status of the motor 13. The first end of the extended extension line 32 is connected to the light board 31, and the second end of the extended extension line 32 is adapted to be pluggably connected to the second end 221 of the extended wiring 22, thereby realizing the signal connection between the control box 2 and the light board 31.

[0047] Optionally, the second end of the extension cable 32 is a female connector, and the second end 221 of the extension cable 22 is a male connector, or the second end of the extension cable 32 and the second end 221 of the extension cable 22 can be connected using other methods known in the art that can achieve signal connection, and the present invention does not impose any restrictions on this.

[0048] In order to facilitate the storage of the connecting wires, the extension wire 32 and the extension wire 22 are both retractable wires, for example, Figure 1 As shown, the extension cord 32 and the extension wiring 22 both include spiral coils, so that the extension cord 32 and the extension wiring 22 can be extended or contracted as needed, making them more convenient to use.

[0049] In other examples, the second end 221 of the extension wire 22 may be exposed from the box body 21 , and the second end of the extension extension wire 32 is adapted to be detachably connected to the second end 221 of the extension wire 22 .

[0050] In other examples, the extended display assembly 3 includes a light board 31 , a signal interface of the light board 31 is located on the light board 31 , and the second end 221 of the extended wiring 22 extends to the outside of the box body 21 and is suitable for being detachably connected to the signal interface on the light board 31 .

[0051] like Figure 1 As shown, the light board 31 of the extended display assembly 3 includes a plurality of first display lights 311, which are arranged in a straight line along the extension direction of the light board 31 and are spaced apart from each other. The plurality of first display lights 311 display the load state of the motor 13 by changing the number of lights and / or the color of the lights. In addition, the plurality of first display lights 311 on the light board 31 may have a certain lighting sequence, for example, the light board 31 has a first end and a second end opposite to each other in its extension direction, and the lighting sequence of the plurality of first display lights 311 is to light up in sequence from the first end of the light board 31 toward the second end.

[0052] Optionally, the plurality of first display lights 311 display the load state of the motor 13 by the number of lights that light up. For example, the greater the load of the motor 13, the greater the number of first display lights 311 that light up in the handle display assembly 423, and the smaller the load of the motor 13, the fewer the number of first display lights 311 that light up in the handle display assembly 423. If all the first display lights 311 in the handle display assembly 423 light up, it means that the motor 13 is in an overload state at this time, and it is necessary to promptly control and stop the motor 13 from running or reduce the load of the motor 13 to protect the motor 13.

[0053] Optionally, the plurality of first display lights 311 display the load state of the motor 13 by emitting light colors. For example, the first display light 311 can emit three different colors of light, namely green light, yellow light and red light. When the first display light 311 displays green light, it indicates that the motor 13 is in a light load state and the motor 13 is operating normally. When the first display light 311 displays yellow light, it indicates that the motor 13 is in a medium load state and the motor 13 is operating normally. When the first display light 311 displays red light, it indicates that the motor 13 is in an overload state and needs to be controlled in time to stop the motor 13 or reduce the load of the motor 13 to protect the motor 13.

[0054] Optionally, the plurality of first display lights 311 display the load status of the motor 13 by the number of lights that light up and the color of the lights that light up. For example, the handle display assembly 423 includes three colors of first display lights 311, namely a green display light, a yellow display light and a red display light, and there is at least one first display light 311 of each color, wherein the green display light is located on the left side of the yellow display light, and the red display light is located on the right side of the yellow display light. As the load level of the motor 13 increases, the green display light, the yellow display light, and the red display light are lit up in sequence from left to right. When all the red display lights are on, it means that the motor 13 is in an overload state, and it is necessary to promptly control and stop the motor 13 or reduce the load of the motor 13 to protect the motor 13.

[0055] In other embodiments, the display mode of the handle display component 423 is not limited thereto. For example, the handle display component 423 may be a light bar / light strip, which may display the load state of the motor 13 through the length and / or color of the brightness bar. The greater the load of the motor 13, the longer the length of the brightness bar, and the smaller the load of the motor 13, the shorter the length of the brightness bar. For another example, the handle display component 423 may be a liquid crystal display screen, which may display numbers used to indicate the load state of the motor 13.

[0056] In some embodiments, the winch device 100 further includes a control handle 4, which is connected to the control box 2 by wire or wirelessly for controlling the operation of the winch 1.

[0057] As an example, Figure 1-Figure 4 As shown, the control handle 4 is connected to the control box 2 by wire. Figure 3 As shown, the control box 2 is provided with a handle interface 25, such as Figure 4 As shown, the control handle 4 has a handle terminal 41 , and the handle terminal 41 is pluggable and engaged in the handle interface 25 .

[0058] Specifically, Figure 3 As shown, the handle interface 25 is exposed from the box body 21. Figure 4 As shown, the control handle 4 includes a handle body 42 and a handle wiring 43. The handle body 42 is provided with a plurality of buttons or knobs for control, and the user controls the operation of the winch 1 by holding the handle body 42. The first end of the handle wiring 43 extends into the handle body 42, and the second end of the handle wiring 43 extends outside the handle body 42. The handle terminal 41 is provided at the second end of the handle wiring 43. When the control handle 4 is not needed, the handle terminal 41 can be separated from the handle interface 25.

[0059] Optionally, the handle interface 25 may be extended to the outside of the box body 21 through wiring, and the handle terminal 41 may be exposed from the handle body 42 , suitable for being pluggably connected to the handle interface 25 .

[0060] Optionally, the control handle 4 can be wirelessly connected to the control box 2 to control the operation of the winch 1. For example, a wireless signal transmission module is provided in the control handle 4 for sending control signals, and a wireless signal receiving module is provided in the control box 2 for receiving control signals. When the user operates the control handle 4, the control handle 4 transmits a wireless signal to the control box 2, and the control box 2 controls the operation of the winch 1 after receiving the command.

The user presses the IN button 421 to control the winch 1 to retract the rope, and the user presses the OUT button 422 to control the winch 1 to release the rope wound on the rope drum 12. The operation is simple and fast. Of course, in other examples, the handle 42 can also be used for other operation buttons.

[0062] In order to make it easier for users to observe the load status of the motor 13, Figure 4 As shown, a handle display component 423 is provided on the handle body 42 of the control handle 4. The handle display component 423 is used to display the load status of the motor 13. The user can observe the load status of the motor 13 from the control handle 4 while using the control handle 4, and the use of the winch device 100 is more convenient.

[0063] exist Figure 4 In the example shown, the handle display component 423 is in the shape of a dial. Figure 4 As shown, the handle display assembly 423 includes a plurality of second display lights 424, which are arranged in an arc shape and spaced apart from each other and are located above the IN button 421 and the OUT button 422. The plurality of second display lights 424 can display the load state of the motor 13 by the number of lights and / or the color of the lights. In addition, the second display lights 424 in the handle display assembly 423 can have a certain lighting order, for example, Figure 4 As shown in , the lighting order of the second display lights 424 is from left to right, or in other examples, the lighting order of the second display lights 424 may be from right to left.

[0064] Optionally, the plurality of second display lights 424 display the load state of the motor 13 by the number of lights that light up. For example, the greater the load of the motor 13, the greater the number of second display lights 424 that light up in the handle display assembly 423, and the smaller the load of the motor 13, the fewer the number of second display lights 424 that light up in the handle display assembly 423. If all the second display lights 424 in the handle display assembly 423 light up, it means that the motor 13 is in an overload state at this time, and it is necessary to promptly control and stop the motor 13 from running or reduce the load of the motor 13 to protect the motor 13.

[0065] Optionally, the plurality of second display lights 424 display the load status of the motor 13 by emitting light colors. For example, the second display lights 424 can emit three different colors of light, namely green light, yellow light and red light. When the second display light 424 displays green light, it indicates that the motor 13 is in a light load state and the motor 13 is operating normally. When the second display light 424 displays yellow light, it indicates that the motor 13 is in a medium load state and the motor 13 is operating normally. When the second display light 424 displays red light, it indicates that the motor 13 is in an overload state and needs to be controlled in time to stop the motor 13 or reduce the load of the motor 13 to protect the motor 13.

[0066] Optionally, the plurality of second display lights 424 display the load status of the motor 13 by the number of lights that light up and the color of the light. For example, the handle display assembly 423 includes three colors of second display lights 424, namely a green display light, a yellow display light and a red display light, and there is at least one second display light 424 of each color, wherein the green display light is located on the left side of the yellow display light, and the red display light is located on the right side of the yellow display light. As the load level of the motor 13 increases, the green display light, the yellow display light, and the red display light are lit from left to right in sequence. When all the red display lights are on, it means that the motor 13 is in an overload state, and it is necessary to promptly control and stop the motor 13 or reduce the load of the motor 13 to protect the motor 13.

[0067] It should be noted that the arrangement of the plurality of second display lights 424 of the handle display assembly 423 is not limited thereto. For example, in other embodiments, the plurality of second display lights 424 may be arranged vertically on the handle body 42, and the second display lights 424 are lit up in order from bottom to top. As the load level of the motor 13 increases, the second display lights 424 are lit up in sequence from bottom to top.

[0068] In other embodiments, the display mode of the handle display component 423 is not limited thereto, and may be other display components. For example, the handle display component 423 may be a light bar / light strip, and the light bar / light strip may display the load state of the motor 13 through the length and / or color of the brightness bar. The greater the load of the motor 13, the longer the length of the brightness bar, and the smaller the load of the motor 13, the shorter the length of the brightness bar. For another example, the handle display component 423 may be a liquid crystal display, and the liquid crystal display may display numbers used to indicate the load state of the motor 13.
