Description

Technical Field

[0001] The utility model belongs to the technical field of winches, and in particular relates to a winch device and a vehicle with the winch device. Background Art

[0002] Winch is commonly used for the rescue of vehicles, ships, etc. The control box of the winch includes a bridge relay connected to a power source for controlling the forward and reverse rotation of the winch, and the bridge relay is connected to a power source such as a vehicle battery. In the related art, a switch is usually set between the bridge relay and the power source. When using the winch, the user needs to operate the manual operation switch to connect the bridge relay and the power source to power the bridge relay. When it stops using, the manual operation switch is used to cut off the power supply to the bridge relay. However, after using the winch, the user usually does not manually operate or forgets to manually operate the switch, causing the bridge relay to be energized all the time. Conductive foreign objects such as insects and mineral sand will enter the control box, causing the circuit to spontaneously combust, affecting safety. Moreover, when using the winch, the user needs to manually operate the switch frequently, which makes the operation more cumbersome and the winch motor frequently started.

[0003] Related technologies also propose to set an automatic switch between the bridge relay and the power supply, set a load detection module in the control box of the winch, the load detection module in the control box is connected to the automatic switch and the motor of the winch through a signal line, and the control board in the control box controls the closing and opening of the automatic switch according to the motor load detected by the load detection module. Since the load detection module in the control box needs to be connected to the automatic switch and the motor through a signal line, the wiring is complicated, and the control box needs to be used in conjunction with the automatic switch, which is inconvenient to modify when used in existing scenarios and has limited use.

[0033] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but cannot be understood as limiting the present invention.

[0034] like Figure 1 and Figure 2 As shown, the winch device 100 of the embodiment of the utility model includes a winch 1, a control box 2 and a switch 3.

[0035] The winch 1 comprises a base frame 11, a rope drum 12 and a motor 13, wherein the rope drum 12 is rotatably mounted on the base frame 11, the motor 13 is mounted on the base frame 11 and connected to the rope drum 11, and the motor 13 is used to drive the rope drum 11 to rotate. The rope drum 11 is used to wind the rope, and the motor 13 drives the rope drum 11 to rotate to retract and release the rope on the rope drum 11.

[0036] The control box 2 is connected between the motor 13 and the switch 3, and includes a bridge relay 21, which is used to control the forward and reverse rotation of the motor 13. For example, the bridge relay 21 controls the motor 13 to rotate forward, and the rope drum 11 releases the wound rope. The bridge relay 21 controls the motor 13 to rotate reversely, and the rope drum 11 recycles the rope and rewinds the released rope onto the rope drum 11.

[0037] The switch 3 is connected to the control box 2 and is suitable for being connected to the power source 5. The switch 3 is used to control the power source 5 to supply power to the bridge relay 21. For example, the power source 5 can be a power source of a vehicle battery. The switch 3 includes a housing 31, a relay 32 and a control board 33. The relay 32 and the control board 33 are arranged in the housing 31. The control board 33 includes a control chip 331, a timer 332 and a detection component 333.

[0038] Among them, the detection component 333 is used to detect the current and / or voltage of the relay 32. When the current and / or voltage detected by the detection component 333 is lower than the preset value and the timing of the timer 332 exceeds the preset time, the control chip 331 controls the relay 32 to disconnect, thereby cutting off the power supply 5 to the bridge relay 21.

[0039] The current preset value and / or voltage preset value of the relay 32 are set, and the preset time of the timer 332 is set. When the detection component 333 detects that the current of the relay 32 is lower than the current preset value, and / or the detection component 333 detects that the voltage of the relay 32 is lower than the voltage preset value, the timer 332 starts timing. If the timing of the timer 332 exceeds the preset time (for example, the preset time is 10 minutes), that is, the current and / or voltage of the relay 32 remain lower than the preset value after the preset time, it can be considered that the winch 1 has stopped using, and the control chip 331 controls the relay 32 to disconnect and the switch 3 to close, thereby cutting off the power supply 5 to the bridge relay 21. The use of the timer 332 to achieve delayed power off is suitable for the situation where the user needs to reuse the winch 1 multiple times in a short period of time, so as to avoid power off when the user only stops using the winch 1.

[0040] The relay 32 has a reset button 321 for manually operating from the outside of the housing 31 to reset the relay 32. When the relay 32 is disconnected, the power supply between the power source 5 and the bridge relay 21 stops, and the winch 1 cannot be activated. When the winch 1 needs to be reactivated, the user operates the reset button 321, the reset button 321 resets the relay 32, the switch 3 is turned on, the circuit is connected, the power supply between the power source 5 and the bridge relay 21 is restored, and the winch 1 can operate normally.

[0041] According to the winch device of the embodiment of the utility model, a switch is set between the bridge relay and the power supply, and a relay and a control board are set in the switch. When the control board detects that the current and / or voltage of the relay always remains lower than the preset value within the preset time, the relay and the power supply are disconnected, thereby cutting off the power supply to the bridge relay, and realizing automatic power-off protection of the winch device. The winch device of the embodiment of the utility model does not need to be provided with a load detection module for detecting the motor load, and has a reasonable design, simple structure, simple wiring, convenient modification, and a wide range of application scenarios.

[0042] In some embodiments, a current preset value of the relay 32 is set, and the control chip 331 controls the relay 32 to be disconnected after the current detected by the detection component 333 is lower than the current preset value and the timing of the timer 332 exceeds a preset time.

[0043] In some embodiments, a preset voltage value of the relay 32 is set, and the control chip 331 controls the relay 32 to disconnect after the current detected by the detection component 333 is lower than the preset voltage value and the timing of the timer 332 exceeds a preset time.

[0044] In some embodiments, the current preset value and voltage preset value of the relay 32 are set, and the control chip 331 controls the relay 32 to disconnect when the current detected by the detection component 333 is lower than the current preset value and the voltage is lower than the voltage preset value, and the timer 332 counts after a preset time.

[0045] In some embodiments, when the current and / or voltage detected by the detection component 333 exceeds a preset value within a preset time, the control chip 331 controls the timer 332 to restart. In other words, when the detection component 333 detects that the current and / or voltage of the relay 32 is lower than the preset value, the timer 332 starts timing. If the timing of the timer 332 does not exceed the preset time, and the detection component 333 detects that the current and / or voltage of the relay 32 exceeds the preset value, it means that the user has restarted the winch 1, and the timer 332 is reset to zero. When the current and / or voltage detected by the detection component 333 is lower than the preset value, the timing restarts.

[0046] For example, the current preset value and the voltage preset value of the relay 32 are set. When at least one of the current and voltage detected by the detection component 333 exceeds the corresponding preset value within the preset time, the control chip 331 controls the timer 332 to reset to zero. When at least one of the current and voltage detected by the detection component 333 is lower than the preset value, the timing is restarted.

[0047] In some embodiments, Figure 1 and Figure 2 As shown, the winch device 100 also includes a control handle 4, which is used to control the operation of the winch 1, and the control handle 4 is connected to the control box 2 by wire or wirelessly. The user can hold the control handle 4 for operation, which is more flexible and convenient. For example, the user can adjust the position so as to observe the operation status at any time, and control the operation of the winch 1 through the control handle 4 in time.

[0048] exist Figure 1 In the example shown, the control handle 4 is wired to the control box 2. The control handle 4 includes a handle body 42 and a handle wiring 41. The handle body 42 is provided with a number 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 41 extends into the handle body 42, and the second end of the handle wiring 41 extends outside the handle body 42. The second end of the handle wiring 41 is provided with a handle terminal. The control box 2 is provided with a handle interface, and the handle terminal of the control handle 4 can be plugged and unplugged into the handle interface of the control box 2. When the control handle 4 is not needed, the handle terminal can be separated from the handle interface.

[0049] like Figure 1 As shown, the handle 42 is provided with an IN button 421 and an OUT button 422. 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.

[0050] exist Figure 2 In the example shown, the control handle 4 is wirelessly connected to the control box 2, the control handle 4 includes a signal generator 43 for sending a control signal, and the control box 2 includes a signal receiver 22 that wirelessly communicates with the signal generator 43, and the signal receiver 22 is used to receive the control signal sent by the signal generator 43. 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 control handle 4 is wirelessly connected to the control box 2, and the user can remotely start the winch 1, which improves the user experience.

[0051] In some embodiments, Figure 5As shown, the control board 33 includes a substrate 334, and the control chip 331, the timer 332 and the detection component 333 are integrated on the substrate 334. Signal connection is achieved through the substrate 334, which improves the integration of the control board 33, reduces line connections, reduces line complexity, and facilitates equipment maintenance.

[0052] In some embodiments, Figure 5 and Figure 6 As shown, the relay 32 has a first terminal 322, a second terminal 323, a third terminal 324 and a fourth terminal 325. The switch 3 further includes an incoming terminal 34 and an outgoing terminal 35.

[0053] The incoming terminal 34 has an incoming inner end and an incoming outer end, the incoming inner end is located in the housing 31 and connected to the first terminal 322, and the incoming outer end is located outside the housing 31 and is suitable for being connected to the positive pole of the power supply 5. The outgoing terminal 35 has an outgoing inner end and an outgoing outer end, the outgoing inner end is located in the housing 32 and connected to the second terminal 323, and the outgoing outer end is located outside the housing 32 and connected to the control box 2. The fourth terminal 325 is connected to the negative pole of the power supply 5 through the grounding line 37. Thus, the relay 32 is connected between the power supply 5 and the control box 2, and can control the power supply 5 to energize the control box 2. When the relay 32 is closed, the power supply 5 supplies power to the control box 2, and the winch 1 can operate normally. The relay 32 is disconnected, and the power supply 5 to the control box 2 is cut off, and the winch 1 cannot operate.

[0054] like Figure 5 and Figure 6 As shown, the control board 33 is connected to the third terminal 324 through a control circuit 361 and a detection circuit 362. The control circuit 361 is used to transmit a control signal to control the relay 32 to be closed or disconnected. The control circuit 361 can be specifically connected to the control chip 331 of the control board 33. The control chip 331 controls the relay 32 to be closed or disconnected through the control circuit 361. The detection circuit 362 is used to transmit a current detection signal and / or a voltage detection signal of the relay 32. The detection circuit 362 can be specifically connected to a detection component 333. The detection component 33 detects the current and / or voltage of the relay 32 through the detection circuit 362, and transmits the current and / or voltage signal of the relay 32 to the control chip 331. The control chip 331 sends a control signal to the relay 32 through the control circuit 361.

[0055] The control board 33 can be powered by an external power supply. In order to reduce the number of components, in some examples, the control board 33 and the relay 32 are both connected to the power supply 5. Figure 5 and Figure 6As shown, the control board 33 is connected to the first terminal 322 through the control board power supply line 363. Since the first terminal 322 is connected to the positive electrode of the power supply 5, the control board 33 is connected to the positive electrode of the power supply 5. The control board 33 is connected to the fourth terminal 325 through the negative electrode connection 364. Since the fourth terminal 325 is connected to the negative electrode of the power supply 5 through the grounding line 37, the control board 33 is connected to the negative electrode of the power supply 5. In this way, the control board 33 is connected to the power supply 5, and the power supply 5 can supply power to the control chip 331, the timer 332 and the detection component 333 of the control board 33. The control board 33 is connected to the relay 32, which reduces the length of the power supply line and reduces the complexity of the line connection. Of course, in other examples, the control board 33 can be connected to other power supplies, or the control board 33 can be directly connected to the positive and negative electrodes of the power supply 5 through the power supply line without passing through the relay 32.

[0056] like Figure 5 and Figure 6 As shown, the reset button 321 is connected between the control board 33 and the positive electrode of the power supply 5. The reset button 321 is closed, and the control board 33 and the positive electrode of the power supply 5 are connected through the reset button 321. When the user needs to activate the winch 1, the reset button 321 is pressed, the reset button 321 is closed, the control chip 331 controls the relay 32 to close through the control line 361, the circuit is connected, the power supply 5 can supply power to the control box 2, and the winch 1 can operate normally.

[0057] like Figure 5 As shown, the switch 3 also includes an incoming line connector 38 and an outgoing line connector 39, one end of the incoming line connector 38 is connected to the incoming line outer end of the incoming line terminal 34, and the other end of the incoming line connector 38 is suitable for being connected to the positive pole of the power supply 5, one end of the outgoing line connector 39 is connected to the outgoing line outer end of the outgoing line terminal 35, and the other end of the outgoing line connector 39 is connected to the control box 2.

[0058] Specifically, Figure 3-5 As shown, the housing 31 of the switch 3 includes a box body 311 and a bottom plate 312. The bottom surface and one side of the box body 311 are open, and the bottom plate 312 is detachably mounted on the bottom surface of the box body 311 to close the bottom surface of the box body 311. Figure 5 As shown, the box body 311 has a first direction (eg Figure 5 The first side surface and the second side surface of the box body 311 are opposite to each other in the direction indicated by the arrow A in FIG. 1 , and the first side surface and the second side surface of the box body 311 are adjacent to an open side surface of the shell 31. The first side surface of the box body 311 is provided with a first reinforcing platform 3111 for supporting the incoming terminal 34, and the second side surface of the box body 311 is provided with a second reinforcing platform 3112 for supporting the outgoing terminal 35.

[0059] like Figure 3-5As shown, the incoming outer end of the incoming terminal 34 extends outward from the first side surface of the housing 31 along the first direction, and the outgoing outer end of the outgoing terminal 35 extends outward from the second side surface of the housing 31 along the first direction.

[0060] The incoming line connector 38 and the outgoing line connector 39 are both columnar, and extend from the shell 31 in parallel and at intervals along the same direction. The extension direction of the incoming line connector 38 and the outgoing line connector 39 is orthogonal to the extension direction of the incoming terminal 34 and the outgoing terminal 35 (i.e., the first direction).

[0061] like Figure 5 As shown, the first terminal 322 , the second terminal 323 , the third terminal 324 and the fourth terminal 325 of the relay 32 face the bottom surface of the box body 311 , and the reset button 321 is exposed from the top surface of the box body 311 .
