[0002] The electric clothes drying rack can be automatically lifted based on the electric lifting mechanism. At present, the control modes of the electric lifting mechanism include remote control, mobile phone APP control, voice control and the like.

[0003] However, the control systems corresponding to the remote control, mobile phone APP control, voice control and the like need to be equipped with the main control circuit board carrying the control circuit and its related accessories, which not only increases the volume and cost of the electric clothes drying rack, but also makes the operation more complicated. Taking the remote control as an example, the remote control and the electric clothes drying rack are usually independent. Before starting the electric clothes drying rack, the user needs to find the remote control first and then operate the remote control to start the electric clothes drying rack. SUMMARY

[0020] The second movable block is configured to move the second limit switch when the motor reverses to the second target stroke, so that the second limit switch is switched from the closed state to the open state.

[0021] In some possible implementation manners, the transmission assembly further comprises a housing, a movable block gear set and a steel wire rope transmission set;

[0022] The steel wire rope transmission set is connected to the output shaft of the motor inside the housing to be driven to rotate by the motor;

[0023] The block dial gear set is rotatably arranged in the shell, and the block dial gear set is connected with the rotating shaft of the steel wire rope transmission set;

[0024] The first block and the second block are respectively connected to different positions of the block dial gear set.

[0025] The first limit switch and the second limit switch are respectively fixed to different positions of the shell.

[0027] The driving gear is connected with the rotating shaft of the steel wire rope transmission set, the driven gear is engaged with the driving gear, and the block dial carrier plate is coaxially connected with the driven gear.

[0028] The first block and the second block are respectively connected to different positions of the block dial carrier plate distributed in the circumferential direction.

[0029] In some possible implementation manners, the lifting control mechanism further comprises a first resistance encountering switch and a second resistance encountering switch, the first resistance encountering switch is electrically connected to a loop on the positive side of the motor, and the second resistance encountering switch is electrically connected to a loop on the negative side of the motor.

When the motor rotates forward, the steel wire rope is recovered through the transmission assembly, so that the lifting device connected with the steel wire rope can rise, and thus the lifting control mechanism realizes the up control of the lifting device. When the motor rotates reversely, the steel wire rope is released through the transmission assembly, so that the lifting device connected with the steel wire rope can descend, and thus the lifting control mechanism realizes the down control of the lifting device. When the motor stops rotating, the position of the transmission assembly is fixed, and thus the position of the steel wire rope is fixed. It can be seen that the lifting control mechanism provided by the embodiment of the present application sets a three-gear six-pin switch as a control switch, and the user only needs to operate the three-gear six-pin switch to be in a target gear, so as to realize the control of the lifting action and the stop of the lifting action of the lifting device, and realize the electric lifting of the lifting device. The lifting device only needs to be mechanically connected with the steel wire rope, without carrying a main control circuit board with a control circuit and related accessories, which not only simplifies the structure of the lifting system, reduces the size and cost of the lifting system, but also makes the lifting operation of the lifting system more simple, efficient and reliable.

DETAILED DESCRIPTION

[0064] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative efforts belong to the scope of the present application.

[0066] To make the technical solutions and advantages of the present application clearer, the embodiments of the present application will be described in further detail below with reference to the drawings.

[0067] The electric clothes rack can be automatically lifted based on the electric lifting mechanism. At present, the control modes of the electric lifting mechanism include remote control, mobile phone APP control, voice control and the like.

[0068] However, the control systems corresponding to the remote control, mobile phone APP control, voice control and the like need to be equipped with the main control circuit board carrying the control circuit and its related accessories, which not only increases the volume and cost of the electric clothes rack, but also makes the operation more cumbersome. Taking the remote control as an example, the remote control and the electric clothes rack are usually independent of each other. Before starting the electric clothes rack, the user needs to find the remote control first, and then operate the remote control to start the electric clothes rack.

[0069] On the one hand, the embodiment of the present application provides a lifting control mechanism, as shown in the accompanying drawings, Figure 1 The lifting control mechanism includes a shell 1, a three-gear six-pin switch 2 located on the shell 1, a motor 3, a transmission assembly 4, a steel wire rope 5 and a power supply module 6 located inside the shell 1.

[0070] The three-gear six-pin switch 2 includes an upward gear, a downward gear and a stop gear, and the motor 3 is connected to the three-gear six-pin switch 2. Figure 2It can be known that the three-gear six-pin switch 2 is electrically connected to the motor 3 to control the motor 3 to rotate forward through the up-gear, to rotate reversely through the down-gear, and to stop rotating through the stop-gear.

[0071] The motor 3, the transmission assembly 4, and the steel wire rope 5 are sequentially connected, the steel wire rope 5 is recovered through the transmission assembly 4 when the motor 3 rotates forward, and the steel wire rope 5 is released through the transmission assembly 4 when the motor 3 rotates reversely.

[0072] The lifting control mechanism provided by the embodiment of the application sets the three-gear six-pin switch 2 as a control switch device, which includes an up-gear, a down-gear, and a stop-gear to control the motor 3 to rotate forward, reversely, and to stop rotating, respectively. The steel wire rope 5 is recovered through the transmission assembly 4 when the motor 3 rotates forward, so that the lifting equipment connected with the steel wire rope 5 can rise, and the lifting control mechanism realizes the up-control of the lifting equipment. The steel wire rope 5 is released through the transmission assembly 4 when the motor 3 rotates reversely, so that the lifting equipment connected with the steel wire rope 5 can descend, and the lifting control mechanism realizes the down-control of the lifting equipment. The motor 3 stops rotating, the position of the transmission assembly 4 is fixed, and the position of the steel wire rope 5 is fixed. It can be seen that the lifting control mechanism provided by the embodiment of the application sets the three-gear six-pin switch 2 as a control switch, and the user only needs to operate the three-gear six-pin switch 2 to make it be in a target gear to realize the control of the lifting action and the stop of the lifting action of the lifting equipment, and realize the electric lifting of the lifting equipment.

[0073] The lifting equipment only needs to be mechanically connected with the steel wire rope 5, without carrying the main control circuit board with a control circuit and related accessories, which not only simplifies the structure of the lifting system, reduces the size, and reduces the cost, but also makes the lifting operation of the lifting system more simple, efficient, and reliable.

[0074] Based on the above example, the wiring mode of the three-gear six-pin switch 2 in the loop of the lifting control mechanism is exemplarily described as follows:

[0075] Referring to Figure 2 and Figure 3 It can be known (wherein, Figure 2 The three-gear six-pin switch 2 includes a first contact 21, a second contact 22, a third contact 23, a fourth contact 24, a fifth contact 25, and a sixth contact 26.

[0076] The first contact 21 and the third contact 23 in the form of static contacts are respectively located on both sides of the second contact 22 in the form of a moving contact; the fourth contact 24 and the sixth contact 26 in the form of static contacts are respectively located on both sides of the fifth contact 25 in the form of a moving contact; the third contact 23 is electrically connected to the fourth contact 24 and the sixth contact 26 through wires respectively, and the sixth contact 26 is also electrically connected to the first contact 21 through a wire. The positive terminal of the motor 3 is electrically connected to the first contact 21, and the negative terminal of the motor 3 is electrically connected to the fourth contact 24; the negative terminal of the power supply module 6 is electrically connected to the second contact 22, and the positive terminal of the power supply module 6 is electrically connected to the fifth contact 25.

[0077] When the three-position six-pin switch 2 is turned to the up position, the second contact 22 is in electrical contact with the first contact 21, and the fifth contact 25 is in electrical contact with the fourth contact 24, and the circuit is connected, so that the current flows from the positive terminal of the motor 3 to the negative terminal of the motor 3, and the motor 3 rotates in the positive direction.

[0078] When the three-position six-pin switch 2 is turned to the down position, the second contact 22 is in electrical contact with the first contact 21, and the fifth contact 25 is in electrical contact with the fourth contact 24, and the circuit is connected, so that the current flows from the negative terminal of the motor 3 to the positive terminal of the motor 3, and the motor 3 rotates in the negative direction.

[0079] In some examples, the three-position six-pin switch 2 further includes a trigger part, which can be designed to be either a pull type or a push type, and the user controls the position of the three-position six-pin switch 2 by operating the trigger part.

[0080] For example, the trigger part is a pull type, and the user randomly switches the rotation state of the motor 3 by pulling the position of the trigger part, thereby controlling the running state of the lifting device, so that the lifting device automatically switches between the up, down and stop states. The trigger part of the three-position six-pin switch 2 is the interactive interface between the user and the lifting system.

[0081] The motor 3 serves as a power device to provide mechanical energy for the recovery and release of the steel wire rope 5 and further for the lifting movement of the lifting device. In some examples, the motor 3 is a direct current brush motor.

[0082] In some implementations, as shown in the accompanying drawings, Figure 4 The first limit switch 71 and the first commutation diode 81 are connected in parallel and are electrically connected in the circuit between the three-position six-pin switch 2 and the positive terminal of the motor 3, and the first limit switch 71 is used to stop the steel wire rope 5 at the upper limit position. The second limit switch 72 and the second commutation diode 82 are connected in parallel and are electrically connected in the circuit between the three-position six-pin switch 2 and the negative terminal of the motor 3, and the second limit switch 72 is used to stop the steel wire rope 5 at the lower limit position.

[0083] Wherein, the first limit switch 71 and the second limit switch 72 are both mechanical switches, when the motor 3 rotates forward to make the steel wire rope 5 move to the upper limit position, the first limit switch 71 is triggered to be disconnected, thereby making the loop be disconnected, the motor 3 stops rotating, and the lifting device defaults to move upward to the highest point.

[0084] Similarly, when the motor 3 reverses to make the steel wire rope 5 move to the lower limit position, the second limit switch 72 is triggered to be disconnected, thereby making the loop be disconnected, the motor 3 stops rotating, and the lifting device defaults to move downward to the lowest point.

[0085] It can be seen that, by setting the first limit switch 71 and the second limit switch 72, the limit movement position of the steel wire rope 5 is detected and fixed, thereby avoiding the steel wire rope 5 from being unlimitedly recovered or released, so as to protect the service life of the steel wire rope 5.

[0086] It can be understood that, by adjusting the timing of the first limit switch 71 and the second limit switch 72 being triggered to be disconnected, the upper limit position and the lower limit position of the steel wire rope 5 can be adjusted to meet the use requirements of users of different heights.

[0087] Under the premise of setting the first limit switch 71 and the second limit switch 72, the first commutation diode 81 and the second commutation diode 82 are further set. The commutation diode is a kind of switch piece, under the action of forward voltage, the resistance is very small, equivalent to a closed switch, under the action of reverse voltage, the resistance is very large, like a broken switch.

[0088] The first commutation diode 81 is connected in parallel with the first limit switch 71, so that the first commutation diode 81 serves as an auxiliary path of the positive side of the motor 3, in the disconnected state of the first limit switch 71, the first commutation diode 81 is in the on state, thereby making the whole loop keep connected, to ensure that the motor 3 reverses smoothly.

[0089] The second commutation diode 82 is connected in parallel with the second limit switch 72, so that the second commutation diode 82 serves as an auxiliary path of the negative side of the motor 3, in the disconnected state of the second limit switch 72, the second commutation diode 82 is in the on state, thereby making the whole loop keep connected, to ensure that the motor 3 rotates forward smoothly.

[0090] It can be seen that, by setting the first commutation diode 81 and the second commutation diode 82, the forward rotation and reverse rotation of the motor 3 are switched, and the motor 3 is protected at the same time.

[0091] Based on the above example of setting limit switches and commutation diodes, the wiring mode of the three-gear six-pin switch 2 in the loop of the lifting control mechanism is exemplarily described as follows:

[0092] Referring to Figure 4 As shown in the figure (wherein, Figure 4 As shown in the figure (wherein, The first contact 21 and the third contact 23 in the form of static contacts are respectively located on both sides of the second contact 22 in the form of a moving contact; the fourth contact 24 and the sixth contact 26 in the form of static contacts are respectively located on both sides of the fifth contact 25 in the form of a moving contact; the third contact 23 is electrically connected to the fourth contact 24 and the sixth contact 26 through wires respectively, and the sixth contact 26 is also electrically connected to the first contact 21 through a wire. The first contact 21 is electrically connected to the first parallel end of the first limit switch 71 and the first parallel end of the first commutating diode 81, and the second parallel end is connected to the positive terminal of the motor 3. The fourth contact 24 is electrically connected to the first parallel end of the second limit switch 72 and the first parallel end of the second commutating diode 82, and the second parallel end is electrically connected to the negative terminal of the motor 3. The negative terminal of the power supply module 6 is electrically connected to the second contact 22, and the positive terminal of the power supply module 6 is electrically connected to the fifth contact 25.

[0093] When the three-position six-pin switch 2 is switched to the up position, the second contact 22 is in electrical contact with the first contact 21, and the fifth contact 25 is in electrical contact with the fourth contact 24, and the circuit is connected, so that the current flows from the positive terminal of the motor 3 to the negative terminal of the motor 3, and the motor 3 rotates in the positive direction.

[0094] When the three-position six-pin switch 2 is switched to the down position, the second contact 22 is in electrical contact with the first contact 21, and the fifth contact 25 is in electrical contact with the fourth contact 24, and the circuit is connected, so that the current flows from the negative terminal of the motor 3 to the positive terminal of the motor 3, and the motor 3 rotates in the reverse direction.

[0095] Figure 5 In some implementations, as shown in the accompanying

[0096] The motor 3 rotates forward to drive the steel wire rope 5 to be retracted, thereby realizing the ascending of the lifting device. When the motor 3 rotates forward to the first target stroke, the transmission assembly 4 also rotates a certain stroke, thereby driving the first shifting block 41 to rotate forward to the corresponding forward rotation limit stroke position. In this way, the first shifting block 41 shifts the first limit switch 71 at the forward rotation limit stroke position, so that the first limit switch 71 is switched from the closed state to the open state. In this way, the circuit is opened, the motor 3 stops rotating forward, and the steel wire rope 5 is retracted to the upper limit position.

[0097] Correspondingly, the motor 3 rotates reversely to drive the steel wire rope 5 to be released, thereby realizing the descending of the lifting device. When the motor 3 rotates reversely to the second target stroke, the transmission assembly 4 also rotates a certain stroke, thereby driving the second shifting block 42 to rotate reversely to the corresponding reverse rotation limit stroke position. In this way, the second shifting block 42 shifts the second limit switch 72 at the reverse rotation limit stroke position, so that the second limit switch 72 is switched from the closed state to the open state. In this way, the circuit is opened, the motor 3 stops rotating reversely, and the steel wire rope 5 is released to the lower limit position.

[0098] Understandably, by adjusting the sizes of the first target stroke and the second target stroke, the timing when the first limit switch 71 and the second limit switch 72 are triggered to be opened can be adjusted.

[0099] The triggering mode of the limit switch is exemplarily described below. In some examples, as shown in FIGS. 1 to 3, the transmission assembly 4 further includes a housing 43, a shifting block gear set 44, and a steel wire rope transmission set 45. Figure 5 and FIGS. 4 to 6, the transmission assembly 4 further includes a housing 43, a shifting block gear set 44, and a steel wire rope transmission set 45. Figure 6 As shown in FIGS. 1 to 3, the steel wire rope transmission set 45 is connected with the output shaft of the motor 3 inside the housing 43 to be driven by the motor 3 to rotate. The shifting block gear set 44 is rotatably arranged in the housing 43 and connected with the rotating shaft of the steel wire rope transmission set 45. The first shifting block 41 and the second shifting block 42 are respectively connected with different positions of the shifting block gear set 44. The first limit switch 71 and the second limit switch 72 are respectively fixed to different positions of the housing 43.

[0100] The steel wire rope transmission set 45 is used to drive the steel wire rope 5 to be retracted or released under the driving of the motor 3. The shifting block gear set 44 is arranged on the outer surface of the housing 43 and connected with the rotating shaft of the steel wire rope transmission set 45, and is used to carry the first shifting block 41 and the second shifting block 42. The motor 3, the steel wire rope transmission set 45, and the shifting block gear set 44 are sequentially driven. In this way, the rotating shifting block gear set 44 drives the first shifting block 41 and the second shifting block 42 thereon to rotate. In this way, not only the positions of the first shifting block 41 and the second shifting block 42 are changed, but also the rotation of the first shifting block 41 and the second shifting block 42 is directly related to the rotation of the motor 3.

[0101] The connection between the steel wire rope transmission group 45 and the steel wire rope 5 will be described as an example: the steel wire rope 5 is arranged to act synchronously, and correspondingly, the steel wire rope transmission group 45 is arranged to be two groups arranged side by side, the steel wire rope transmission group 45 includes a rope reel and a transmission gear coaxially connected, the two rope reels of the two groups of steel wire rope transmission groups 45 are respectively wound with one steel wire rope 5, and the output shaft of the motor 3 is connected with the two transmission gears through a worm mechanism, so that the synchronous driving of the two groups of steel wire rope transmission groups 45 is realized through the motor 3.

[0102] In some examples, as shown in the accompanying drawings, the dial gear set 44 includes a driving gear 441, a driven gear 442, and a dial carrier 443; the driving gear 441 is connected with the rotating shaft of the steel wire rope transmission group 45, the driven gear 442 is engaged with the driving gear 441, and the dial carrier 443 is coaxially connected with the driven gear 442; the first dial 41 and the second dial 42 are respectively connected with different positions distributed in the circumferential direction of the side of the dial carrier 443. Figure 6

[0103] When the steel wire rope transmission group 45 is designed as two groups, the driving gear 441 is connected with the rotating shaft of any one of the steel wire rope transmission groups 45, which can be determined according to the requirements of space layout. For example, the rotating shaft of the steel wire rope transmission group 45 farther away from the limit switch can be connected with the driving gear 441.

[0104] The driving gear 441 is designed as one, and one, two, three or more driven gears 442 can be designed according to actual needs. For example, as shown in the accompanying drawings, three driven gears 442 are exemplified, wherein the driving gear 441 is a pinion gear, the driving gear 441 is engaged with a first driven gear 442 in the form of a gear wheel, the first driven gear 442 is coaxially connected with a second driven gear 442 in the form of a pinion gear, the second driven gear 442 is engaged with a third driven gear 442 in the form of a gear wheel, and the third driven gear 442 is coaxially connected with the dial carrier 443, so that the third driven gear 442 drives the dial carrier 443 to rotate synchronously. Figure 6

[0105] The structure of the dial gear set 44 is thus arranged, which not only enables the rotation of the dial, but also ensures that the stroke of the motor 3 and the stroke of the dial are accurately and reliably converted.

[0106] In this example, the first limit switch 71 and the second limit switch 72 can be arranged in a row, one above the other, to correspond to the first dial 41 and the second dial 42 at different radial positions, respectively.

[0107] In some implementations, as shown in the accompanying drawings, the first dial 41 and the second dial 42 are arranged to be staggered in the circumferential direction, and the first limit switch 71 and the second limit switch 72 are arranged to be staggered in the circumferential direction. Figure 7 ​​As shown, the lifting control mechanism provided in this embodiment of the invention further includes a first obstruction switch 91 and a second obstruction switch 92. The first obstruction switch 91 is electrically connected to the circuit on the positive side of the motor 3, and the second obstruction switch 92 is electrically connected to the circuit on the negative side of the motor 3. Both the first obstruction switch 91 and the second obstruction switch 92 are used to disconnect when the wire rope 5 encounters an obstruction.

[0108] The wire ropes 5 are configured to operate synchronously in two parts. The first obstruction switch 91 is used to detect the obstruction status of one of the wire ropes 5, and the second obstruction switch 92 is used to detect the obstruction status of the other wire rope 5.

[0109] By setting a first obstruction switch 91 and a second obstruction switch 92, which are respectively located in the circuits on both sides of the motor 3, the status of the wire rope 5 is monitored in real time. When the wire rope 5 encounters an obstruction, the switch is disconnected, thereby causing the motor 3 to stop rotating, thus achieving the purpose of protecting the wire rope 5.

[0110] Based on the above example of setting limit switches and commutator diodes, the wiring method of the three-position six-pin switch 2 in the circuit of the lifting control mechanism is described below as an example:

[0111] See Figure 7 It can be seen that (among them, Figure 7 An example of a three-position six-pin switch 2 in the stop position is shown. The three-position six-pin switch 2 includes a first contact 21, a second contact 22, a third contact 23, a fourth contact 24, a fifth contact 25, and a sixth contact 26. The first contact 21 and the third contact 23, which are static contacts, are located on either side of the second contact 22, which is a moving contact. The fourth contact 24 and the sixth contact 26, which are static contacts, are located on either side of the fifth contact 25, which is a moving contact. The third contact 23 is electrically connected to the fourth contact 24 and the sixth contact 26 via wires, and the sixth contact 26 is also electrically connected to the first contact 21 via a wire. The first parallel terminal of the first limit switch 71 and the first commutating diode 81 is electrically connected to the first contact 21, and the second parallel terminal is connected to the positive terminal of the motor 3. The first parallel terminal of the second limit switch 72 and the second commutating diode 82 is electrically connected to the fourth contact 24, and the second parallel terminal is connected to the negative terminal of the motor 3. The negative terminal of the power supply module 6 is electrically connected to the second contact 22, and the positive terminal of the power supply module 6 is electrically connected to the fifth contact 25.

[0112] The first obstacle detection switch 91 can be connected in series at any position in the circuit. For example, the first obstacle detection switch 91 can be located in the circuit between the negative terminal of the power supply module 6 and the second contact 22 (see [link]). Figure 7 Alternatively, the first obstacle detection switch 91 is located in the circuit between the second parallel terminal of the first limit switch 71 and the first commutation diode 81 and the positive terminal of the motor 3 (not shown in the figure).

[0113] The second obstacle detection switch 92 can be connected in series at any position in the circuit. For example, the second obstacle detection switch 92 can be located in the circuit between the positive terminal of the power supply module 6 and the fifth contact 25 (see [link]). Figure 7 Alternatively, the second obstacle detection switch 92 is located in the circuit between the second limit switch 72 and the second parallel terminal of the second commutation diode 82 and the negative terminal of the motor 3 (not shown in the figure).

[0114] When the three-position six-pin switch 2 is moved to the up position, the second contact 22 makes electrical contact with the first contact 21, and the fifth contact 25 makes electrical contact with the fourth contact 24, thus completing the circuit. Current then flows from the positive terminal of motor 3 to the negative terminal, causing motor 3 to rotate forward. Until motor 3 reaches the first target stroke, the first limit switch 71 is activated by the first toggle block 41, disconnecting the circuit and stopping motor 3's forward rotation.

[0115] When the three-position six-pin switch 2 is moved to the down position, the second contact 22 makes electrical contact with the first contact 21, and the fifth contact 25 makes electrical contact with the fourth contact 24, thus completing the circuit. Current then flows from the negative terminal of motor 3 to the positive terminal, causing motor 3 to reverse. This continues until motor 3 reaches the second target stroke, at which point the second limit switch 72 is activated by the second toggle block 42, disconnecting the circuit and stopping motor 3 from reversing.

[0116] During the forward or reverse rotation of motor 3, if the wire rope 5 encounters an obstruction, the first obstruction switch 91 or the second obstruction switch 92 will be triggered and disconnected, thereby breaking the circuit and stopping motor 3 from rotating.

[0117] In some implementations, such as the appendix Figure 5 and attached Figure 8 As shown, the housing 1 has a first elastic lever 101 and a second elastic lever 102. When the wire rope 5 is in a tensioned state, the first elastic lever 101 and the second elastic lever 102 are elastically pressed against the first position by the wire rope 5. When the wire rope 5 encounters resistance and is in a slack state, the first elastic lever 101 and the second elastic lever 102 return to their original positions. One of the first and second positions is the position where the resistance switch is activated, and the other is the position where the resistance switch is disengaged.

[0118] During both the retraction and release movements, the wire rope 5 is in a taut state. Under normal movement, the first elastic lever 101 and the second elastic lever 102 are elastically pressed against and confined to the first position by the wire rope 5. Once the wire rope 5 encounters resistance, it will switch from a taut state to a partially slack state, causing either the first elastic lever 101 or the second elastic lever 102 to reset to the second position.

[0119] The obstruction detection switch can be either a normally closed switch or a normally open switch. The specific position type of the first and second positions is determined according to the type of obstruction detection switch. For example, if the first obstruction detection switch 91 and the second obstruction detection switch 92 are normally closed switches, the wire rope 5 is in a taut state during both the retraction and release movements. In the normal movement state of the wire rope 5, the first elastic lever 101 and the second elastic lever 102 are elastically pressed against the first position by the wire rope 5. Therefore, the first position is the position where the elastic levers are disengaged from the obstruction detection switch, and thus the first obstruction detection switch 91 and the second obstruction detection switch 92 remain in a normally closed state.

[0120] Once the wire rope 5 encounters an obstruction, it will switch from a tensioned state to a partially slack state. In this way, the first elastic lever 101 or the second elastic lever 102 will reset to the second position. The second position is the position where the elastic lever will activate the obstruction switch. Thus, the first obstruction switch 91 and the second obstruction switch 92 will be activated and switched to the disconnected state.

[0121] Furthermore, as shown in the appendix Figure 8 As shown, the housing 1 is provided with a first track groove 11 and a second track groove 12; the first end of the first elastic lever 101 is connected to the housing 1, and the second end is accommodated in the first track groove 11. The first track groove 11 is used to guide and limit the movement of the second end of the first elastic lever 101; the first end of the second elastic lever 102 is connected to the housing 1, and the second end is accommodated in the second track groove 12. The second track groove 12 is used to guide and limit the movement of the second end of the second elastic lever 102.

[0122] The shape of the first track groove 11 is the same as the movement trajectory of the second end of the first elastic lever 101, and the shape of the second track groove 12 is the same as the movement trajectory of the second end of the second elastic lever 102. Using the first track groove 11 and the second track groove 12, the movement of the first elastic lever 101 and the second elastic lever 102 can be guided, allowing them to quickly reach their positions, thereby achieving rapid switching of the obstruction-detection switch. Furthermore, the first track groove 11 and the second track groove 12 can also limit the movement of the second ends of the first elastic lever 101 and the second elastic lever 102, respectively, ensuring that the elastic levers can only move along the corresponding track grooves.

[0123] For example, the first elastic lever 101 and the second elastic lever 102 have the same structure. For example, both include a first connecting section, a second connecting section and a third connecting section. The first connecting section, the second connecting section and the third connecting section are connected in sequence and cooperate to form a U-shape or similar U-shape. The first end of the elastic lever is the free end of the first connecting section, the second end of the elastic lever is the free end of the third connecting section, the third connecting section is located on one side of the corresponding wire rope 5, and the obstruction switch is located on the other side of the corresponding wire rope 5.

[0124] The shell 1 comprises a base and a cover, the first resistance switch 91, the second resistance switch 92, the first elastic lever 101, the second elastic lever 102, the first track slot 11 and the second track slot 12 are arranged on the base of the shell 1.
