Description

[Technical Field]

[0001] The present invention relates to the technical field of drives, and in particular to manual open / close drives. [Background technology]

[0002] Shutters, windows, etc. are usually equipped with a drive unit, which drives the opening and closing of shutters and windows, making people's lives much more convenient. Generally, the operation of the drive unit can be controlled by a terminal tool such as a remote control or a mobile phone, which is very convenient. However, if the terminal tool breaks down, for example, if there is no electricity or signal, it will be impossible to control the normal operation of the drive unit. In such cases, people will be embarrassed and will be unable to close or open the shutter or window. To address the above issues, it is common to provide an emergency switch somewhere other than the stroke head of the drive unit. However, since this switch is attached to the top of the shutter or window along with the drive unit, it can only be used by climbing up, which is very inconvenient. Summary of the Invention [Problem to be solved by the invention]

[0003] In contrast to the current state of the prior art, the technical problem that the present invention aims to solve is to provide a manual opening / closing drive device that is easy to operate and allows the operation of the drive device to be manually controlled by simply standing under the shutter or window, without the need to climb up. [Means for solving the problem]

[0004] The technical solution of the present invention used to solve the above technical problems is as follows: A manual opening / closing drive device includes an outer tube, in which a reducer, a motor movement, an electric control panel, a power source, and a stroke head are sequentially installed, the electric control panel is fixed in the outer tube by a fixed rack, the electric control panel is provided with a voltage sensor for controlling start / stop of the drive device, the electric control panel is further provided with a trigger switch for connecting / disconnecting a circuit and causing the voltage sensor to detect a change in voltage, a sliding member is provided on the fixed rack, the sliding member can contact or disengage from the trigger switch to connect / disconnect the circuit to the trigger switch to change the voltage, an operating member is connected to the sliding member, the sliding member can be driven to contact or disengage from the trigger switch, and one end of the operating member passes through the stroke head and hangs down naturally so that it can be pulled by hand.

[0005] Furthermore, the execution member includes a return spring that separates the sliding member from the trigger switch, and a towing rope that can be pulled to bring the sliding member into contact with the trigger switch, one end of the towing rope being fixed to the sliding member, and the other end passing through the stroke head and then naturally hanging down so that it can be pulled by hand.

[0006] Furthermore, the sliding member is provided with a groove for avoiding the trigger switch, and an arc-shaped guide surface for contacting the trigger switch is provided in the groove on the side away from the towing rope.

[0007] Furthermore, the sliding member has a draw hole at the end facing the towing rope for tying the towing rope.

[0008] Furthermore, one end of the return spring abuts against the end of the sliding member facing the towing rope, and the other end of the return spring abuts against the boss of the fixed rack.

[0009] Furthermore, the motor movement and the power supply are both electrically connected to an electric control panel, the output end of the motor movement is connected to the input end of the reducer, the output end of the reducer is arranged to be exposed to the outside of the outer tube, and the reducer and the motor movement are both fixedly connected within the outer tube.

[0010] Additionally, the power supply is mounted in a fixed rack.

[0011] Furthermore, the head portion of the stroke head is exposed to the outside of the outer tube, the neck portion of the stroke head is inserted into the outer tube, a guide post for switching the direction of the towing rope is provided within the stroke head, and a through hole through which the towing rope passes is provided in the side wall of the head portion of the stroke head.

[0012] Furthermore, the fixed rack includes a removable upper case and a removable lower case. [Effects of the Invention]

[0013] Compared with the prior art, the present invention has the following advantages: In the present invention, the execution member is provided which passes through the stroke head and hangs down naturally, making it easy for the user to stand below the shutter or window and pull it with their hands, without the user having to climb up. By pulling the execution member, the execution member drives the sliding member to abut against the trigger switch, making the circuit conductive and causing a voltage change. The voltage change is detected by the voltage sensor, and then the electric control panel controls the corresponding operation of the drive unit, which then releases the execution member and causes the sliding member to disengage from the trigger switch, which breaks the circuit. The trigger switch's conduction and disconnection, i.e., pulling and releasing the execution member, are performed in a single operation. During this process, the voltage sensor detects the voltage change, and the electric control panel controls the corresponding operation of the drive unit according to the voltage sensor signal, making operation easier; and because the trigger switch, the sliding member, and part of the execution member are directly mounted within the outer tube and not on the stroke head, the exposed portion of the stroke head can be made thinner, which reduces the side clearance and reduces exposure when installing the shutter or window.

[0022] As shown in Figures 1 to 6, the present invention includes an outer tube 1, in which a reducer 2, a motor movement 3, an electric control panel 4, a power supply 5 and a stroke head 6 are sequentially arranged, the motor movement 3 and the power supply 5 are all electrically connected to the electric control panel 4, the electric control panel 4 is an MCU board, the output end of the motor movement 3 is connected to the input end of the reducer 2, the output end of the reducer 2 is exposed to the outside of the outer tube 1 for transmission, the reducer 2 and the motor movement 3 are all fixedly connected in the outer tube 1, the electric control panel 4 is fixed in the outer tube 1 by a fixed rack 7, and a voltage for controlling the start and stop of the driving device is provided. A sensor 8 is provided on the electric control panel 4, a trigger switch 9 is further provided on the electric control panel 4 for making / breaking a circuit and causing the voltage sensor 8 to detect a change in voltage, a sliding member 10 is provided on the fixed rack 7 and can contact or disengage from the trigger switch 9 to make / break the circuit in the trigger switch 9 to change the voltage, an execution member 11 is connected to the sliding member 10 and can be driven so that the sliding member 10 contacts or disengages from the trigger switch 9, one end of the execution member 11 passes through a stroke head 6 and hangs down naturally so that it can be pulled by hand.

[0023] Here, the execution member 11 includes a return spring 11.1 that separates the sliding member 10 from the trigger switch 9, and a pulling rope 11.2 that can pull the sliding member 10 to abut against the trigger switch 9. One end of the pulling rope 11.2 is fixed to the sliding member 10, and the other end passes through the stroke head 6 and hangs down naturally so that it can be pulled by hand, making it easy for a user to stand below the shutter / window and pull the pulling rope 11.2. By pulling the pulling rope 11.2, the user can drive the sliding member 10 to slide and bring it into contact with the trigger switch 9, causing it to be electrified. After releasing the pulling rope 11.2, the pulling rope 11.2 returns under the action of the return spring 11.1 and separates from the trigger switch 9, breaking the circuit. Each time the execution member 11 pulls the sliding member 10 to make or break the trigger switch 9, the electric control panel 4 controls the corresponding operation of the driving device according to the signal from the voltage sensor 8.

[0024] Here, the sliding member 10 is provided with a recessed groove 10.1 for avoiding the trigger switch 9, and an arc-shaped guide surface 10.2 for contacting the trigger switch 9 is provided on the side of the recessed groove 10.1 away from the towing rope 11.2. When the towing rope 11.2 is pulled downward, the sliding member 10 slides toward the towing rope 11.2, and the arc-shaped guide surface 10.2 pushes up the trigger switch 9, energizing it. When the towing rope 11.2 is released, the sliding member 10 returns to the position under the action of the return spring 11.1. Upon returning, the arc-shaped guide surface 10.2 disengages from the trigger switch 9, causing the trigger switch 9 to drop into the groove 10.1 and cut off the circuit. The structure of the groove 10.1 on the one hand serves to avoid the trigger switch 9, and on the other hand limits the sliding range of the sliding member 10, ensuring that the sliding member 10 does not slide excessively away from the towing rope 11.2 when returning. The trigger switch 9 abuts against the side of the groove 10.1 closest to the towing rope 11.2, limiting excessive sliding of the sliding member 10.

[0025] Here, the end of the sliding member 10 facing the towing rope 11.2 is provided with a draw hole 10.3 for binding the towing rope 11.2.

[0026] Here, one end of the return spring 11.1 abuts against the end of the sliding member 10 facing the towing rope 11.2, and the other end of the return spring 11.1 abuts against the boss 7.1 of the fixed rack 7. In its natural state, the return spring 11.1 positions the groove 10.1 of the sliding member 10 below the trigger switch 9, thereby avoiding the trigger switch 9 and preventing current from flowing. When the towing rope 11.2 is pulled, the towing rope 11.2 pulls the sliding member 10 and presses the return spring 11.1, bringing the arc-shaped guide surface 10.2 close to the trigger switch 9 and pushing up the trigger switch 9 to allow current to flow.

[0027] Here, the power supply 5 is mounted in a fixed rack 7, and the power supply 5 and the electric control panel 4 are mounted integrally by the fixed rack 7 and then mounted in the outer tube 1, which makes the overall structure neater and easier to assemble. The fixed rack 7 also serves to prevent dust and scratches, preventing metal chips remaining in the outer tube 1 from falling onto the electric control panel 4 and causing malfunctions such as short circuits. It also prevents friction with the outer tube 1 when assembling the electric control panel 4 and the power supply 5. Since electric wires are welded to the electric control panel 4 and the power supply 5, many more small components are welded to the electric control panel 4. The protection of the fixed rack 7 improves assembly efficiency and makes friction less likely to occur.

[0028] Here, the head portion 6.1 of the stroke head 6 is exposed to the outside of the outer tube 1, and a PCB board is provided within the head portion 6.1, and the PCB board is connected to the electric control panel 4 via a flat cable. The PCB board is provided with setting keys, a data interface, indicator lights, an antenna, etc., all of which are conventional technology and will not be described again. The neck portion 6.2 of the stroke head 6 is inserted into the outer tube 1, and a guide post 6.3 for switching the direction of the towing rope 11.2 is provided within the stroke head 6. A through hole 6.4 through which the towing rope 11.2 passes is provided in the side wall of the head portion 6.1 of the stroke head 6, as shown in Figure 6.

[0029] Here, the fixed rack 7 includes a removable upper case 7.2 and a removable lower case 7.3, which makes it easy to remove and assemble.

[0030] When in use, a user can stand under the shutter or window and directly pull the towing rope 11.2. The towing rope 11.2 overcomes the elastic force of the return spring 11.1 to drive the sliding member 10 to slide in the direction of the towing rope 11.2. The arc-shaped guide surface 10.2 of the sliding member 10 pushes up the trigger switch 9 to make the circuit conductive. The voltage sensor 8 detects the voltage change, and the electrical control panel 4 controls the corresponding operation of the driving device according to the signal from the voltage sensor 8. After releasing the towing rope 11.2, the sliding member 10 pulls back the return spring 11.1. 1.1, the trigger switch 9 returns to its original position, and the trigger switch 9 drops into the groove 10.1 to break the circuit. The trigger switch 9 turns on and off, i.e., the towing rope 11.2 is pulled and released in one operation. During this process, the voltage sensor 8 detects the voltage change, and the electric control panel 4 controls the corresponding operation of the drive unit according to the signal from the voltage sensor 8. This is easy to operate. In actual use, the corresponding operating circuit can be set up in the electric control panel 4 by itself. For example, the towing rope 11.2 is pulled and released in the first operation, the voltage sensor 8 detects the voltage change, and the electric control panel 4 controls the corresponding operation of the drive unit according to the signal from the voltage sensor 8. In response to the signal from No. 8, the drive unit is controlled to rotate clockwise, the towing rope 11.2 is pulled and released the second time, the electric control panel 4 controls the drive unit to stop rotating, the towing rope 11.2 is pulled and released the third time, the electric control panel 4 controls the drive unit to rotate counterclockwise, the towing rope 11.2 is pulled and released the fourth time, the electric control panel 4 controls the drive unit to stop rotating, the towing rope 11.2 is pulled and released the fifth time, the electric control panel 4 also controls the drive unit to rotate clockwise, and so on, operating in a cycle. Furthermore, when the drive unit rotates clockwise to move the shutter or window to its uppermost or lowermost limit position, the electric control panel 4 controls the drive unit to stop operating, and at this time, the towing rope 11.2 is pulled and released, and the electric control panel 4 controls the drive unit to rotate counterclockwise, thereby skipping the intermediate stopping step. Similarly, when the drive unit rotates counterclockwise to move the shutter or window to its uppermost or lowermost limit position, the electric control panel 4 controls the drive unit to stop operating, and at this time, the towing rope 11.2 is towed and released, and the electric control panel 4 controls the drive unit to rotate clockwise, thereby skipping the intermediate stopping step.

[0031] The materials, reagents and experimental equipment used in the examples of the present invention are all commercially available products that fit into the field of shutter and window tubular motors, unless otherwise specified.
