The electric clothes hanger can be based on the automatic rising of electric lift mechanism, and at present, electric lift mechanism's control mode includes remote controller control, cell-phone APP control, speech control etc..
However, control systems corresponding to remote controller control, mobile phone APP control, voice control and other modes all need to be equipped with a main control circuit board carrying a control circuit and related accessories thereof, which not only increases the size and cost of the electric laundry rack, but also makes the operation of the electric laundry rack cumbersome.
In one aspect, an embodiment of the present invention provides a lifting control mechanism, as shown in fig. 1, the lifting control mechanism includes: the device comprises a shell 1, a three-gear six-foot switch 2 positioned on the shell 1, a motor 3 positioned inside the shell 1, a transmission assembly 4, a steel wire rope 5 and a power supply module 6.
Third gear six-legged switch 2 is including rising the gear, descending the gear and stopping the gear, and it can be known to combine fig. 2, and third gear six-legged switch 2 electric connection is in motor 3 to through 3 corotation of gear control motor that rise, through 3 reversals of gear control motor that descend, through stopping gear control motor 3 stall.
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 forwards, and the steel wire rope 5 is released through the transmission assembly 4 when the motor 3 rotates backwards.
According to the lifting control mechanism provided by the embodiment of the invention, the three-gear six-pin switch 2 is arranged as a control switch device, and comprises an ascending gear, a descending gear and a stopping gear, so as to be respectively used for controlling the motor 3 to rotate forwards, controlling the motor 3 to rotate backwards and controlling the motor 3 to stop rotating. When the motor 3 rotates forwards, the steel wire rope 5 is recovered through the transmission assembly 4, so that the lifting equipment connected with the steel wire rope 5 can ascend, and the lifting control mechanism realizes the ascending control of the lifting equipment. When the motor 3 rotates reversely, the steel wire rope 5 is released through the transmission assembly 4, so that the lifting device connected with the steel wire rope 5 can descend, and the lifting control mechanism realizes descending control of the lifting device. When the motor 3 stops rotating, the transmission assembly 4 is fixed, and then the steel wire rope 5 is fixed. As can be seen, in the lifting control mechanism provided in the embodiment of the present invention, the three-position hexapod switch 2 is used as the control switch, and the user only needs to operate the three-position hexapod switch 2 to make it be in the target gear, so that the lifting action and the stopping of the lifting action of the lifting device can be controlled, and the electric lifting of the lifting device is realized.
The lifting equipment is only mechanically connected with the steel wire rope 5, and a main control circuit board with a control circuit and related accessories thereof do not need to be carried, so that the structure of the lifting system is simplified, the size of the lifting system is reduced, the cost of the lifting system is reduced, and the lifting operation of the lifting system is simpler, more efficient and more reliable.
Based on the above example, the following description is made for the exemplary wiring manner of the three-position hexapod switch 2 in the circuit of the lift control mechanism:
referring to fig. 2 and 3 (wherein fig. 2 illustrates the three-position hexapod 2 in the stop position), the three-position hexapod 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.
A first contact 21 and a third contact 23 in the form of stationary contacts are located on either side of a second contact 22 in the form of a moving contact; a fourth contact 24 in the form of a fixed contact and a sixth contact 26 are located on either side of a 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 by wires, respectively, and the sixth contact 26 is also electrically connected to the first contact 21 by wires. 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.
When the three-gear six-pin switch 2 is shifted to a rising gear, the second contact 22 is electrically contacted with the first contact 21, the fifth contact 25 is electrically contacted with the fourth contact 24, and the loop is closed, so that current flows from the positive end of the motor 3 to the negative end of the motor 3, and the motor 3 rotates forwards.
When the three-gear six-foot switch 2 is shifted to a descending gear, the second contact 22 is electrically contacted with the first contact 21, the fifth contact 25 is electrically contacted with the fourth contact 24, the circuit is connected, and thus, the current flows from the negative pole end of the motor 3 to the positive pole end of the motor 3, and the motor 3 rotates reversely.
In some examples, the third-gear hexapod 2 further comprises a trigger portion, which may be designed as a toggle or push type, and a user controls the gear of the third-gear hexapod 2 by operating the trigger portion.
For example, the triggering part is of a toggle type, a user can toggle the position of the triggering part to switch the rotation state of the motor 3 at will, and further control the running state of the lifting device, so that the lifting device can be automatically switched in a rising, falling and stopping state, and the triggering part of the three-gear six-foot switch 2 belongs to an interactive interface between the user and the lifting system.
The motor 3 serves as a power means for recovering and releasing the wire rope 5 and further providing mechanical kinetic energy for the lifting movement of the lifting device. In some examples, the motor 3 is a dc brushed motor.
In some implementations, as shown in fig. 4, the lift control mechanism further includes a first limit switch 71, a second limit switch 72, a first commutation diode 81, and a second commutation diode 82; the first limit switch 71 is connected with the first reversing diode 81 in parallel, and is integrally and electrically connected to a loop between the three-gear six-pin switch 2 and the positive terminal of the motor 3, and the first limit switch 71 is used for stopping the steel wire rope 5 at the upper limit position; the second limit switch 72 is connected in parallel with the second commutation diode 82, and is integrally electrically connected to a loop between the three-gear six-pin switch 2 and the negative terminal of the motor 3, and the second limit switch 72 is used for stopping the steel wire rope 5 at the lower limit position.
The first limit switch 71 and the second limit switch 72 are both mechanical switches, and when the motor 3 rotates forward to enable the steel wire rope 5 to move to the upper limit position in a recovery mode, the first limit switch 71 is triggered to be disconnected, so that the loop is disconnected, the motor 3 stops rotating, and the lifting device moves to the highest point in an ascending mode in a default mode.
Similarly, when the motor 3 rotates reversely to release the wire rope 5 to move to the lower limit position, the second limit switch 72 is triggered to be switched off, so that the circuit is switched off, the motor 3 stops rotating, and the lifting device moves to the lowest point by default.
It can be seen that the first limit switch 71 and the second limit switch 72 are arranged to detect and fix the extreme movement position of the steel wire rope 5, so as to prevent the steel wire rope 5 from being recycled or released without limit, and to protect the service life of the steel wire rope 5.
It can be understood that the upper limit position and the lower limit position of the steel wire rope 5 can be adjusted by adjusting the time when the first limit switch 71 and the second limit switch 72 are triggered to be turned off, so as to meet the use requirements of users with different heights.
On the premise that the first limit switch 71 and the second limit switch 72 are provided, the embodiment of the present disclosure further provides a first commutation diode 81 and a second commutation diode 82. The commutation diode, as a switching element, has a very low resistance under forward voltage, corresponding to an on switch, and a very high resistance under reverse voltage, corresponding to an off switch.
The first commutation diode 81 is connected in parallel with the first limit switch 71, so that the first commutation diode 81 is used as a sub-circuit for the positive side of the motor 3, and when the first limit switch 71 is in the off state, the first commutation diode 81 is in the on state, so that the whole circuit is kept connected to ensure the smooth reverse rotation of the motor 3.
The second commutation diode 82 is connected in parallel with the second limit switch 72, so that the second commutation diode 82 serves as a sub-circuit on the negative electrode side of the motor 3, and when the second limit switch 72 is in the off state, the second commutation diode 82 is in the on state, so that the whole circuit is kept connected, and the motor 3 is ensured to rotate forward smoothly.
It can be seen that the first commutation diode 81 and the second commutation diode 82 are provided to switch the normal rotation and the reverse rotation of the motor 3 while protecting the motor 3.
Based on the above example provided with limit switches and commutation diodes, the following is an exemplary description of the way in which the three-position hexapod 2 is wired in the circuit of the lift control mechanism:
referring to fig. 4 (wherein fig. 4 illustrates that the third-speed hexapod 2 is in the stop position), the third-speed hexapod 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. A first contact 21 in the form of a stationary contact and a third contact 23 are located on either side of a second contact 22 in the form of a moving contact; fourth and sixth contacts 24 and 26 in the form of stationary contacts are located on either side of a 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 by wires, respectively, and the sixth contact 26 is also electrically connected to the first contact 21 by wires. The first limit switch 71 and the first parallel terminal of the first commutation diode 81 are 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 terminals of the second limit switch 72 and the second commutation diode 82 are electrically connected to the fourth contact 24, and the second parallel terminal 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.
When the three-gear six-foot switch 2 is shifted to a rising gear, the second contact 22 is electrically contacted with the first contact 21, the fifth contact 25 is electrically contacted with the fourth contact 24, the circuit is connected, and thus, current flows from the positive pole end of the motor 3 to the negative pole end of the motor 3, and the motor 3 rotates forwards.
When the three-gear six-foot switch 2 is shifted to a descending gear, the second contact 22 is electrically contacted with the first contact 21, the fifth contact 25 is electrically contacted with the fourth contact 24, the circuit is connected, and thus, the current flows from the negative pole end of the motor 3 to the positive pole end of the motor 3, and the motor 3 rotates reversely.
In some implementations, as shown in fig. 5, the first limit switch 71 and the second limit switch 72 are both normally closed switches; the transmission assembly 4 comprises a first shifting block 41 and a second shifting block 42 which can rotate, the first shifting block 41 is configured to shift the first limit switch 71 when the motor 3 rotates forwards to a first target stroke, so that the first limit switch 71 is switched from a closed state to an open state; the second dial 42 is configured to dial the second limit switch 72 when the motor 3 reversely rotates to the second target stroke, so that the second limit switch 72 is switched from the closed state to the open state.
When the motor 3 rotates forwards to a first target stroke, the transmission assembly 4 correspondingly rotates for a certain stroke, and then the first shifting block 41 is driven to rotate forwards to a corresponding forward rotation limit stroke position, so that the first shifting block 41 shifts the first limit switch 71 at the forward rotation limit stroke position, the first limit switch 71 is switched from a closed state to an open state, a loop is disconnected, the motor 3 stops rotating forwards, and the steel wire rope 5 moves to an upper limit position in a recovery mode.
Correspondingly, the motor 3 rotates reversely to drive the steel wire rope 5 to be released, so that the lifting device descends, when the motor 3 rotates reversely to a second target stroke, the transmission assembly 4 also rotates for a certain stroke correspondingly, and then the second shifting block 42 is driven to rotate reversely to a corresponding reverse limit stroke position, so that the second shifting block 42 shifts the second limit switch 72 at the reverse limit stroke position, the second limit switch 72 is switched from a closed state to an open state, so that the loop is disconnected, the motor 3 stops rotating reversely, and the steel wire rope 5 moves to a lower limit position in a releasing manner.
It can be understood that 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 turn off can be adjusted.
In the following, the triggering mode of the limit switch is exemplarily described, and in some examples, as shown in fig. 5 and fig. 6, the transmission assembly 4 further includes: a shell 43, a shifting block gear set 44 and a steel wire rope transmission set 45; the wire rope transmission group 45 is connected with the output shaft of the motor 3 in the shell 43 so as to be driven by the motor 3 to rotate; the shifting block gear set 44 is rotatably arranged on the shell 43, and the shifting block gear set 44 is connected with a rotating shaft of the steel wire rope transmission set 45; the first shifting block 41 and the second shifting block 42 are respectively connected to different positions of the shifting block gear set 44; the first limit switch 71 and the second limit switch 72 are fixed to different positions of the housing 43, respectively.
The wire rope transmission set 45 is used for driving the wire rope 5 to perform recovery motion or release motion under the driving of the motor 3, and the shifting block gear set 44 is arranged on the outer surface of the shell 43 and connected with a rotating shaft of the wire rope transmission set 45 and used for bearing the first shifting block 41 and the second shifting block 42. The motor 3, the steel wire rope transmission group 45 and the shifting block gear group 44 are sequentially driven, so that the rotating shifting block gear group 44 drives the first shifting block 41 and the second shifting block 42 on the rotating shifting block gear group to rotate, and therefore not only is the position change of the first shifting block 41 and the second shifting block 42 realized, 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.
The following is an exemplary description of the connection between the wire rope drive pack 45 and the wire rope 5: the two steel wire ropes 5 are arranged to act synchronously, correspondingly, the two steel wire rope transmission groups 45 are arranged in two groups which are arranged side by side, each steel wire rope transmission group 45 comprises a rope reel and a transmission gear which are coaxially connected, the two rope reels of the two steel wire rope transmission groups 45 are respectively wound by one steel wire rope 5, and the output shaft of the motor 3 is meshed with the two transmission gears through a worm mechanism, so that the two steel wire rope transmission groups 45 are synchronously driven through the motor 3.
In some examples, as shown in fig. 6, the dial gear set 44 includes: a driving gear 441, a driven gear 442, and a dial plate 443; the driving gear 441 is connected with a rotating shaft of the steel wire rope transmission set 45, the driven gear 442 is meshed with the driving gear 441, and the shifting block carrying disc 443 is coaxially connected with the driven gear 442; the first paddle 41 and the second paddle 42 are connected to different positions of the side portion of the paddle tray 443 in the circumferential direction.
When the two wire rope transmission sets 45 are designed to be two sets, the driving gear 441 is connected to a rotating shaft of any one of the wire rope transmission sets 45, which may be determined according to the requirement of spatial layout. For example, the rotation shaft of the wire rope transmission set 45 further away from the limit switch may be connected to the driving gear 441.
The driving gear 441 is designed to be one, and one, two, three or more driven gears 442 can be designed according to actual requirements. For example, fig. 6 illustrates three driven gears 442, 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 gearwheel, 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 gearwheel, and the third driven gear 442 is coaxially connected with the dial 443 such that the third driven gear 442 drives the dial 443 to rotate synchronously.
The structure of the shifting block gear set 44 is arranged in this way, so that the rotation of the shifting blocks can be realized, and the stroke of the motor 3 and the stroke of the shifting blocks can be accurately and reliably converted.
In such an example, the first limit switch 71 and the second limit switch 72 may be arranged in columns, one above and one below, to correspond to the first block 41 and the second block 42, respectively, at different radial positions.
In some implementations, as shown in fig. 7, the lifting control mechanism further includes a first blocking switch 91 and a second blocking switch 92, where the first blocking switch 91 is electrically connected to the circuit on the positive side of the motor 3, and the second blocking switch 92 is electrically connected to the circuit on the negative side of the motor 3; the first blocking switch 91 and the second blocking switch 92 are both used for being disconnected when the steel wire rope 5 is blocked.
The two steel wire ropes 5 are arranged to act synchronously, the first blocking switch 91 is used for detecting the blocking state of one steel wire rope 5, and the second blocking switch 92 is used for detecting the blocking state of the other steel wire rope 5.
Through setting up first meeting and hindering switch 91 and second meeting and hindering switch 92, both are arranged in the return circuit of motor 3 both sides respectively to and monitor wire rope 5's state in time, break off when wire rope 5 meets and hinders, and then make motor 3 stall, thereby reach the purpose of protection wire rope 5.
Based on the above example provided with the limit switch and the commutation diode, the following description is made exemplarily about the wiring manner of the three-gear hexapod switch 2 in the loop of the lift control mechanism:
referring to fig. 7 (wherein fig. 7 illustrates the three-position hexapod 2 in the stop position), the three-position hexapod 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. A first contact 21 in the form of a stationary contact and a third contact 23 are located on either side of a second contact 22 in the form of a moving contact; a fourth contact 24 in the form of a fixed contact and a sixth contact 26 are located on either side of a 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 by wires, respectively, and the sixth contact 26 is also electrically connected to the first contact 21 by wires. The first limit switch 71 and the first parallel terminal of the first commutation diode 81 are 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 terminals of the second limit switch 72 and the second commutation diode 82 are electrically connected to the fourth contact 24, and the second parallel terminal 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.
The first encounter resistance switch 91 may be connected in series at any position in the circuit, for example, the first encounter resistance switch 91 is disposed in the circuit between the negative terminal of the power supply module 6 and the second contact 22 (see fig. 7), or the first encounter resistance switch 91 is disposed 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).
The second encounter resistance switch 92 may be connected in series at any position in the loop, for example, the second encounter resistance switch 92 is disposed in the loop between the positive terminal of the power supply module 6 and the fifth contact 25 (see fig. 7), or the second encounter resistance switch 92 is disposed in the loop 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).
When the three-gear six-foot switch 2 is shifted to a rising gear, the second contact 22 is electrically contacted with the first contact 21, the fifth contact 25 is electrically contacted with the fourth contact 24, the circuit is connected, and thus, current flows from the positive pole end of the motor 3 to the negative pole end of the motor 3, and the motor 3 rotates forwards. Until the motor 3 rotates forward to the first target stroke, the first limit switch 71 is switched off by the first shifting block 41, the circuit is disconnected, and the motor 3 stops rotating forward.
When the three-gear six-foot switch 2 is shifted to a descending gear, the second contact 22 is electrically contacted with the first contact 21, the fifth contact 25 is electrically contacted with the fourth contact 24, the circuit is connected, and thus, the current flows from the negative pole end of the motor 3 to the positive pole end of the motor 3, and the motor 3 rotates reversely. Until the motor 3 rotates forwards to the second target travel, the second limit switch 72 is switched off by the second shifting block 42, the circuit is disconnected, and the motor 3 stops rotating backwards.
During the forward rotation or reverse rotation of the motor 3, once the steel wire 5 is blocked, the first blocking switch 91 or the second blocking switch 92 is triggered to be switched off, and the circuit is switched off, so that the motor 3 stops rotating.
In some implementations, as shown in fig. 5 and 8, housing 1 has first and second elastic stems 101, 102 thereon; when the steel wire rope 5 is in a tensioned state, the first elastic deflector rod 101 and the second elastic deflector rod 102 are respectively elastically pressed at a first position by the steel wire rope 5; when the steel wire rope 5 is in a relaxed state when meeting a resistance, the first elastic deflector rod 101 and the second elastic deflector rod 102 reset and move to the second position. One of the first position and the second position is a position for shifting the encountering resistance switch, and the other position is a position for separating from the encountering resistance switch.
The steel wire rope 5 is in a tensioned state in the process of recovery movement and release movement, and the first elastic shifting rod 101 and the second elastic shifting rod 102 are elastically pressed by the steel wire rope 5 and limited at the first position in the normal movement state of the steel wire rope 5. As soon as cable 5 encounters a resistance, cable 5 is switched from the tensioned state to the partially relaxed state, so that first elastic lever 101 or second elastic lever 102 moves back into the second position.
The specific position types of the first position and the second position are determined according to the type of the resistance-encountering switch. For example, the first encounter stop switch 91 and the second encounter stop switch 92 are normally closed switches, the steel wire 5 is under tension during the recovery movement and the release movement, and in the normal movement state of the steel wire 5, the first elastic shift lever 101 and the second elastic shift lever 102 are elastically pressed by the steel wire 5 to a first position, and then the first position is a position where the elastic shift lever is separated from the encounter stop switch, so that the first encounter stop switch 91 and the second encounter stop switch 92 are kept in a normally closed state.
Once the steel wire rope 5 encounters a resistance, the steel wire rope 5 is switched from the tension state to the local relaxation state, so that the first elastic shifting lever 101 or the second elastic shifting lever 102 moves to the second position in a resetting manner, and then the second position is the position where the elastic shifting lever toggles the resistance encountering switch, so that the first resistance encountering switch 91 and the second resistance encountering switch 92 are toggled to be switched to the off state.
Further, as shown in fig. 8, the housing 1 is provided with a first track groove 11 and a second track groove 12; the first end of the first elastic shifting rod 101 is connected to the shell 1, the second end of the first elastic shifting rod is accommodated in the first track groove 11, and the first track groove 11 is used for guiding and limiting the movement of the second end of the first elastic shifting rod 101; a first end of the second elastic shift lever 102 is connected to the housing 1, and a second end is received in the second track groove 12, the second track groove 12 being used to guide and limit the movement of the second end of the second elastic shift lever 102.
The shape of the first track groove 11 is the same as the movement track of the second end of the first elastic shifting rod 101, the shape of the second track groove 12 is the same as the movement track of the second end of the second elastic shifting rod 102, and the first track groove 11 and the second track groove 12 can guide the movement of the first elastic shifting rod 101 and the second elastic shifting rod 102 to enable the first elastic shifting rod 101 and the second elastic shifting rod 102 to move in place quickly, so that the quick switching of the switch meeting the resistance is realized. In addition, the first track groove 11 and the second track groove 12 may also limit the second end of the first elastic shift lever 101 and the second end of the second elastic shift lever 102, respectively, so that the elastic shift lever can only move along the corresponding track grooves.
For example, the first elastic shift lever 101 and the second elastic shift lever 102 have the same structure, for example, both of them include a first connection section, a second connection section and a third connection section, which are sequentially connected and matched to form a U-shape or a similar U-shape, wherein the first end of the elastic shift lever is a free end of the first connection section, the second end of the elastic shift lever is a free end of the third connection section, the third connection section is located on one side of the corresponding steel wire rope 5, and the emergency switch is located on the other side of the corresponding steel wire rope 5.
The housing 1 includes a base and a cover, and the first blocking switch 91, the second blocking switch 92, the first elastic toggle lever 101, the second elastic toggle lever 102, the first track groove 11 and the second track groove 12 are disposed on the base of the housing 1.
