[0005] This technical solution realizes the integrated electric and manual control of the sunshade while retaining all the functions of the traditional manual roller blinds, while optimizing the drawbacks of the single-sided power transmission of other electric roller blind pull rods. Specifically, the device adopts a single-sided power and double-sided synchronous belt transmission solution; on both sides of the drum component, a right support component and a left support component are respectively provided, both of which are equipped with synchronous wheels and connected to the pull rod component through a synchronous belt.

[0006] In addition, the electric and manual integrated synchronous belt sunshade device according to the present invention also has the following additional technical features: According to one embodiment of the present invention, the driving component includes a linear motor, a limit block, an electromagnetic clutch, a bearing seat and a position sensor connected in sequence. The output shaft of the linear motor is connected to the electromagnetic clutch through the limit block, and the output shaft is connected to the gear component through the bearing seat, and the position sensor is installed on the gear component.

[0007] The driving component of this technical solution provides power through a linear motor, an electromagnetic clutch realizes the engagement and separation of power, a bearing seat and a gear component realize the transmission and conversion of power, and a position sensor provides position feedback, which together constitute an efficient and accurate electric drive and mechanical transmission system. Specifically, a DC motor is installed on the mounting seat to provide power for the electric control of the roller blind; the limit block is installed on the output shaft of the linear motor, and when the electromagnetic clutch is powered off, the friction plate is separated from the clutch body to realize the manual control function and limit the movement range of the friction plate; the electromagnetic clutch is installed between the linear motor and the bearing seat, and the motor power transmission and interruption are realized by connecting and disconnecting the friction plate, and the smoothness when the sunshade is manually pulled is ensured; the clutch fixing seat is installed on the bearing seat to stabilize the electromagnetic clutch; the bearing seat is installed on the mounting seat, and is composed of a bearing seat and two deep groove ball bearings, which provide support and fixation for the electromagnetic clutch, the output shaft, and the driving gear; the position sensor is installed on the driving gear and the gear set housing, converts the movement of the roller blind into an electrical signal, records the rotation data of the gear component, and transmits it to the main control board.

[0008] According to one embodiment of the present invention, the gear composition includes a driving gear connected to the output shaft of the linear motor, a driven gear connected to the core shaft, and an idler gear located between the driving gear and the driven gear; the power of the linear motor is transmitted to the core shaft through the driving gear, the idler gear, and the driven gear, respectively, driving the synchronous wheel on the core shaft to rotate, thereby driving the pull rod composition located on the synchronous belt to move up and down relative to the winding drum composition, thereby realizing the winding action of the sunshade cloth.

[0009] In the present technical solution, a linear motor is used as a power source, and its output shaft is connected to a driving gear; when the linear motor is working, its output shaft will generate a rotational motion, thereby driving the driving gear to rotate; the driving gear is meshed with an idler gear, and the idler gear plays the role of an intermediate power transmission, which can transmit the rotational motion of the driving gear to the driven gear, and the transmission speed and torque are adjusted by changing the number of teeth of the idler gear; the idler gear is then meshed with the driven gear, and the driven gear is connected to the mandrel, and when the idler gear drives the driven gear to rotate, it also drives the mandrel to rotate together; a synchronous wheel is installed on the mandrel, and the synchronous wheel is connected to a synchronous belt; when the mandrel rotates, the synchronous wheel will also rotate accordingly, and transmit the rotational motion to the pull rod assembly through the synchronous belt; the pull rod assembly is connected to the synchronous belt through a clamp, and when the synchronous belt moves, the pull rod assembly will also move with it; the up and down movement of the pull rod assembly drives the winding action of the sunshade cloth; when the pull rod assembly moves upward, the sunshade cloth will be wound on the reel assembly; when the pull rod assembly moves downward, the sunshade cloth will be released.

[0010] According to one embodiment of the present invention, a limit sensor is installed on the synchronous belt, and the limit sensor includes a limit plate and a photoelectric sensor. The photoelectric sensor is installed above the driven wheel assembly, and the limit plate is located on the synchronous belt where the sunshade curtain reaches the limit position. When the synchronous belt reaches the limit position, the limit plate blocks the photoelectric sensor, triggering the output signal of the photoelectric sensor.

[0011] This technical solution achieves precise control and protection of the extreme positions of the sunshade cloth by installing a limit sensor on the synchronous belt and using a photoelectric sensor to detect the presence of a limit plate, which not only improves the automation level of the sunshade system, but also enhances its safety and reliability. Specifically, the synchronous belt only connects the driving component and the pull rod component, and also carries the winding and unfolding actions of the sunshade cloth. To ensure that the sunshade cloth can accurately stop at the predetermined position, a limit sensor needs to be installed on the synchronous belt; the limit sensor consists of a limit plate and a photoelectric sensor. The limit plate is a marker fixed on the synchronous belt and is located on the synchronous belt when the sunshade cloth reaches the extreme position. The extreme position is the position where the sunshade cloth is fully wound or fully unfolded; the photoelectric sensor is installed above the driven wheel component to detect the presence of the limit plate. The photoelectric sensor usually consists of a light emitter and a light receiver. When there is no obstruction between the two, the light emitted by the light emitter can reach the light receiver smoothly, and the photoelectric sensor is in an untriggered state; when the synchronous belt drives the limit plate to move in front of the photoelectric sensor, the limit plate will block the light emitted by the light emitter, causing the light receiver to be unable to receive the light, the photoelectric sensor is triggered, and its output signal will change; the control system judges according to the preset logic. When the photoelectric sensor is triggered, it means that the sunshade cloth has reached the limit position. At this time, it is necessary to stop the movement of the linear motor or change its movement direction to prevent the sunshade cloth from being damaged due to excessive retraction or unfolding.

[0012] According to one embodiment of the present invention, the driven wheel assembly also includes a pre-tensioning frame, the bottom of the pre-tensioning frame is mounted on the bracket by screws, and a pre-tensioning wheel is fixed on the inner side of the pre-tensioning frame; the synchronous belt extending upward through the movable pulley is tensioned through the pre-tensioning wheel, and the tension of the synchronous belt is adjusted by the pre-tensioning frame.

[0013] In this technical solution, the pre-tensioning wheel is located on the moving path of the synchronous belt. During the transmission process, the synchronous belt will pass through the driven pulley and extend upward, and then bypass the pre-tensioning wheel, so that the synchronous belt can maintain a certain tension during the transmission process, thereby ensuring the stability and stability of the transmission; the pre-tensioning frame allows the tension of the synchronous belt to be adjusted; by adjusting the position of the pre-tensioning frame relative to the bracket, the contact position and angle between the pre-tensioning wheel and the synchronous belt are changed, thereby achieving the adjustment of the tension of the synchronous belt. In actual applications, the tension of the synchronous belt will be affected by many factors, such as temperature changes, material aging, load changes, etc.; if the synchronous belt is too loose, it will cause inaccurate transmission, slippage or increased wear; if the synchronous belt is too tight, it will increase the resistance and wear of the transmission system, and even cause damage to the synchronous belt or related components; the tension of the synchronous belt is adjusted by the pre-tensioning frame to ensure that the transmission system can maintain the best working condition under various working conditions.

[0014] According to one embodiment of the present invention, a main control component is arranged above the middle of the reel component, and the main control component receives signals from the position sensor and the limit sensor to control the actions of the linear motor and the electromagnetic clutch.

[0015] In the present technical solution, the reel component is responsible for the winding and unfolding of the sunshade cloth, while the limit sensor is used to detect whether the sunshade cloth has reached the limit position to prevent damage caused by excessive winding or unfolding; when the main control component receives the signal, it precisely controls the action of the linear motor and the electromagnetic clutch; the linear motor serves as the power source of the sunshade system, and its motion state (such as speed, acceleration, stop position, etc.) directly determines the winding and unfolding speed of the sunshade cloth; and the electromagnetic clutch is used to achieve power engagement and disengagement when necessary, ensuring that the sunshade system can work stably under different working conditions; the main control component controls the linear motor and the electromagnetic clutch by sending control signals. When the main control component needs to change the motion state of the linear motor, it will send a corresponding control signal to the driver of the linear motor, thereby achieving precise control of the linear motor; when it is necessary to control the engagement and disengagement of the electromagnetic clutch, the main control component will also send a corresponding control signal to the controller of the electromagnetic clutch.

[0016] According to one embodiment of the present invention, the main control component includes a main control seat, a main control board and wiring terminals. The main control board is placed in the main control seat, and the main control board is respectively connected to the right support component and the limit sensor through the wiring terminals; the main control board receives control information, controls the direction and speed of the linear motor, controls the closing and opening states of the electromagnetic clutch, transmits the state of the sunshade cloth to the master control machine, receives control instructions from the master control machine and executes them.

[0017] This technical solution realizes the automatic control and status monitoring of the sunshade system by receiving and processing sensor signals through the main control board, and accurately controlling the linear motor and electromagnetic clutch, thereby improving the control accuracy and stability of the system and enhancing the safety of the system; remote monitoring of the sunshade system is achieved through communication between the master control computer and the main control board.

[0018] According to one embodiment of the present invention, the right support component, the left support component, the driven wheel component, and the main control component are all fixed to the wall panel, the drum component is relatively stationary, and the pull rod component drives the sunshade curtain to retract relative to the drum component.

[0019] This technical solution ensures the stability of the entire sunshade system through the fixed installation of the right support component, the left support component, the driven wheel component and the main control component; the relative stillness of the drum component provides a stable reference point for the winding and unfolding of the sunshade cloth; the connection between the pull rod component and the synchronous belt, and the interaction with the sunshade cloth, realize the winding and unfolding of the sunshade cloth; the main control component receives signals from sensors (such as position sensors, limit sensors, etc.), processes these signals according to preset control logic, and sends control instructions to actuators such as linear motors; the linear motor performs precise rotational motion according to the received instructions, thereby driving the drum component to rotate, and then realizing the winding and unfolding of the sunshade cloth.

[0020] According to one embodiment of the present invention, an anti-sliding block is provided on the inner side of the synchronous belt.

[0021] In this technical solution, an anti-slip block is arranged on the inner side of the synchronous belt to significantly increase the contact area and friction between the synchronous belt and the transmission wheel; the anti-slip block is usually made of a material with a high friction coefficient, which can firmly grasp the surface of the transmission wheel and maintain stable transmission even under harsh working conditions.

[0022] In order to achieve the above-mentioned purpose, the present invention also provides a method for using the electric and manual integrated synchronous belt sunshade device.

[0023] A method for using an electric and manual integrated synchronous belt sunshade device comprises the following steps: S1, the linear motor starts, transmits power to the core shaft through the electromagnetic clutch and gear, and drives the synchronous wheel to rotate; S2, the synchronous belt rotates with the synchronous wheel and is guided by the guide wheel, thereby driving the pull rod assembly to move up and down, and then retracting or unfolding the sunshade cloth; the tension of the synchronous belt is adjusted by the pre-tensioning wheel; S3, the position sensor monitors the position of the pull rod, and the limit sensor is triggered when the sunshade cloth reaches the limit position; S4, the main control component receives the limit sensor and position sensor signals, controls the linear motor and electromagnetic clutch, and transmits the sunshade cloth status to the master control machine.

[0024] This technical solution realizes the automatic control of the sunshade cloth. Specifically, by starting the linear motor, the power is effectively transmitted to the core shaft by using the transmission mechanism composed of the electromagnetic clutch and the gear, thereby driving the rotation of the synchronous wheel; the synchronous belt rotates with the rotation of the synchronous wheel, and the pull rod assembly is driven to move up and down by the guiding effect of the guide wheel; the tension of the synchronous belt is accurately adjusted by the preload wheel to ensure the stability and efficiency of the transmission; the up and down movement of the pull rod directly realizes the winding or unfolding function of the sunshade cloth; the position sensor monitors the position of the pull rod in real time, and the limit sensor is triggered in time when the sunshade cloth reaches the limit position. The role of the sensor is to ensure that the movement of the sunshade cloth is carried out within a predetermined range to avoid damage or failure caused by excessive movement; the main control component receives signals from the limit sensor and the position sensor, and accurately controls the linear motor and the electromagnetic clutch according to these signals; the main control component also transmits the state information of the sunshade cloth to the master control computer to realize remote monitoring of the sunshade system.

[0025] Compared with the prior art, the present invention has the following beneficial effects: On the premise of retaining all the functions of traditional manual roller blinds, the device adopts a single-sided power and double-sided synchronous belt drive solution, which not only significantly improves the stability and efficiency of the transmission, but also ensures the stability of the sunshade fabric during the winding and unfolding process, and optimizes the disadvantages of single-sided power transmission of traditional electric roller blinds.

[0042] In addition, the electric and manual integrated synchronous belt 7 sunshade device according to the present invention also has the following additional technical features: like Figures 2 to 4As shown, the driving component 11 includes a linear motor 111, a limit block 112, an electromagnetic clutch 113, a bearing seat 114 and a position sensor 115 which are connected in sequence. The output shaft of the linear motor 111 is connected to the electromagnetic clutch 113 through the limit block 112, and the output shaft is connected to the gear component 13 through the bearing seat 114, and the gear component 13 is equipped with a position sensor 115.

[0043] The driving component 11 of the present technical solution provides power through the linear motor 111, the electromagnetic clutch 113 realizes the engagement and separation of power, the bearing seat 114 and the gear component 13 realize the transmission and conversion of power, and the position sensor 115 provides position feedback, together forming an efficient and precise electric drive and mechanical transmission system. Specifically, a DC motor is mounted on the mounting base 15 to provide power for the electric control of the roller blind; a limit block 112 is mounted on the output shaft of the linear motor 111, and when the electromagnetic clutch 113 is powered off, the friction plate is separated from the clutch body to realize the manual control function and limit the movement range of the friction plate; the electromagnetic clutch 113 is mounted between the linear motor 111 and the bearing seat 114, and the motor power transmission and interruption are realized by connecting and disconnecting the friction plate, and smoothness is ensured when the sunshade is manually pulled; the clutch fixing seat is mounted on the bearing seat 114 to stabilize the electromagnetic clutch 113; the bearing seat 114 is mounted on the mounting base 15, and is composed of the bearing seat 114 and two deep groove ball bearings, which provide support and fixation for the electromagnetic clutch 113, the output shaft, and the driving gear 121; the position sensor 115 is mounted on the driving gear 121 and the gear set housing, and converts the movement of the roller blind into an electrical signal, records the rotation data of the gear group 13, and transmits it to the main control board.

[0044] like Figures 2 to 4 As shown, the gear assembly 13 includes a driving gear 121 connected to the output shaft of the linear motor 111, a driven gear 123 connected to the core shaft 31, and an idler gear 122 located between the driving gear 121 and the driven gear 123; the power of the linear motor 111 is transmitted to the core shaft 31 through the driving gear 121, the idler gear 122, and the driven gear 123, respectively, driving the synchronous wheel 12 on the core shaft 31 to rotate, thereby driving the pull rod assembly 4 located on the synchronous belt 7 to move up and down relative to the reel assembly 3, thereby realizing the winding action of the sunshade cloth.

[0045] In the present technical solution, the linear motor 111 is used as a power source, and its output shaft is connected to the driving gear 121; when the linear motor 111 is working, its output shaft will generate a rotational motion, thereby driving the driving gear 121 to rotate; the driving gear 121 is meshed with the idler gear 122, and the idler gear 122 plays the role of an intermediate power transmission, which can transmit the rotational motion of the driving gear 121 to the driven gear 123, and the transmission speed and torque can be adjusted by changing the number of teeth of the idler gear 122; the idler gear 122 is then meshed with the driven gear 123, and the driven gear 123 is connected to the core shaft 31. When the idler gear 12 2 drives the driven gear 123 to rotate, and also drives the core shaft 31 to rotate; the core shaft 31 is mounted with a synchronous wheel 12, and the synchronous wheel 12 is connected to the synchronous belt 7; when the core shaft 31 rotates, the synchronous wheel 12 also rotates accordingly, and transmits the rotational motion to the tie rod assembly 4 through the synchronous belt 7; the tie rod assembly 4 is connected to the synchronous belt 7 through a clamp, and when the synchronous belt 7 moves, the tie rod assembly 4 also moves with it; the up and down movement of the tie rod assembly 4 drives the winding action of the sunshade cloth; when the tie rod assembly 4 moves upward, the sunshade cloth is wound on the reel assembly 3; when the tie rod assembly 4 moves downward, the sunshade cloth is released.

[0046] According to one embodiment of the present invention, a limit sensor 6 is installed on the synchronous belt 7. The limit sensor 6 includes a limit plate and a photoelectric sensor. The photoelectric sensor is installed above the driven wheel assembly 5. The limit plate is located on the synchronous belt 7 where the sunshade cloth reaches the limit position. When the synchronous belt 7 reaches the limit position, the limit plate blocks the photoelectric sensor and triggers the output signal of the photoelectric sensor.

[0047] This technical solution achieves precise control and protection of the extreme position of the sunshade cloth by installing a limit sensor 6 on the synchronous belt 7 and using a photoelectric sensor to detect the presence of a limit plate, which not only improves the automation level of the sunshade system, but also enhances its safety and reliability. Specifically, the synchronous belt 7 only connects the driving component 11 and the pull rod component 4, and also carries the winding and unfolding actions of the sunshade cloth. To ensure that the sunshade cloth can accurately stop at a predetermined position, it is necessary to install a limit sensor 6 on the synchronous belt 7; the limit sensor 6 consists of a limit plate and a photoelectric sensor. The limit plate is a marker fixed on the synchronous belt 7 and is located on the synchronous belt 7 when the sunshade cloth reaches the extreme position. The extreme position is the position where the sunshade cloth is fully wound or fully unfolded; the photoelectric sensor is installed above the driven wheel component 5 to detect the presence of a limit plate. The photoelectric sensor usually consists of a light emitter and a receiver. When there is no obstruction between the two, the light emitted by the light emitter can smoothly reach the light receiver, and the photoelectric sensor is in an untriggered state; when the synchronous belt 7 drives the limit plate to move in front of the photoelectric sensor, the limit plate will block the light emitted by the light emitter, resulting in the light receiver being unable to receive the light, the photoelectric sensor is triggered, and its output signal will change; the control system judges according to the preset logic. When the photoelectric sensor is triggered, it means that the sunshade cloth has reached the limit position. At this time, it is necessary to stop the movement of the linear motor 111 or change its movement direction to prevent the sunshade cloth from being damaged due to excessive retraction or unfolding.

[0048] like Figures 9 and 10 As shown, the driven wheel assembly 5 also includes a pre-tensioning frame, the bottom of which is mounted on the bracket 51 by screws, and a pre-tensioning wheel 53 is fixed on the inner side of the pre-tensioning frame; the synchronous belt 7 extending upward through the movable pulley is tensioned through the pre-tensioning wheel 53, and the tension of the synchronous belt 7 is adjusted by the pre-tensioning frame.

[0049] In this technical solution, the pre-tensioning wheel 53 is located on the moving path of the synchronous belt 7. During the transmission process, the synchronous belt 7 will pass through the driven pulley 52 and extend upward, and then bypass the pre-tensioning wheel 53, so that the synchronous belt 7 can maintain a certain tension during the transmission process, thereby ensuring the stability and stability of the transmission; the pre-tensioning frame allows the tension of the synchronous belt 7 to be adjusted; by adjusting the position of the pre-tensioning frame relative to the bracket 51, the contact position and angle between the pre-tensioning wheel 53 and the synchronous belt 7 are changed, thereby achieving the adjustment of the tension of the synchronous belt 7. In practical applications, the tension of the synchronous belt 7 will be affected by many factors, such as temperature changes, material aging, load changes, etc.; if the synchronous belt 7 is too loose, it will cause inaccurate transmission, slippage or increased wear; if the synchronous belt 7 is too tight, it will increase the resistance and wear of the transmission system, and even cause damage to the synchronous belt 7 or related components; the tension of the synchronous belt 7 is adjusted by the pre-tensioning frame to ensure that the transmission system can maintain the best working state under various working conditions.

When the main control component 8 needs to change the motion state of the linear motor 111, it will send a corresponding control signal to the driver of the linear motor 111, thereby realizing precise control of the linear motor 111; when it is necessary to control the engagement and separation of the electromagnetic clutch 113, the main control component 8 will also send a corresponding control signal to the controller of the electromagnetic clutch 113.

[0055] The present technical solution ensures the stability of the entire sunshade curtain system by fixedly installing the right support component 1, the left support component 2, the driven wheel component 5 and the main control component 8; the relative stillness of the reel component 3 provides a stable reference point for the winding and unfolding of the sunshade curtain cloth; the connection between the pull rod component 4 and the synchronous belt 7, and the interaction with the sunshade curtain cloth, realize the winding and unfolding of the sunshade curtain cloth; the main control component 8 receives signals from sensors (such as position sensors 115, limit sensors 6, etc.), processes these signals according to preset control logic, and sends control instructions to actuators such as the linear motor 111; the linear motor 111 performs precise rotational motion according to the received instructions, thereby driving the reel component 3 to rotate, thereby realizing the winding and unfolding of the sunshade curtain cloth.

[0056] According to one embodiment of the present invention, an anti-sliding block is provided on the inner side of the synchronous belt 7 .

[0057] In the present technical solution, an anti-sliding block is arranged on the inner side of the synchronous belt 7, which significantly increases the contact area and friction between the synchronous belt 7 and the transmission wheel; the anti-sliding block is usually made of a material with a high friction coefficient, which can firmly grasp the surface of the transmission wheel and maintain stable transmission even under harsh working conditions.

[0058] Example 2 Based on Example 1, Figures 1 to 12 As shown, this embodiment provides a method for using an electric and manual integrated synchronous belt 7 sunshade device, comprising the following steps: S1, the linear motor 111 is started, and the power is transmitted to the core shaft 31 through the electromagnetic clutch 113 and the gear assembly 13, driving the synchronous wheel 12 to rotate; S2, the synchronous belt 7 rotates with the synchronous wheel 12 and is guided by the guide wheel 14, thereby driving the pull rod assembly 4 to move up and down, and then retracting or unfolding the sunshade cloth; the tension of the synchronous belt 7 is adjusted by the pre-tensioning wheel 53; S3, the position sensor 115 monitors the position of the pull rod, and the limit sensor 6 is triggered when the sunshade cloth reaches the limit position; S4, the main control component 8 receives the signals of the limit sensor 6 and the position sensor 115, controls the linear motor 111 and the electromagnetic clutch 113, and transmits the state of the sunshade cloth to the master control machine.

[0059] This technical solution realizes the automatic control of the sunshade cloth. Specifically, by starting the linear motor 111, the electromagnetic clutch 113 and the transmission mechanism of the gear assembly 13 are used to effectively transmit the power to the core shaft 31, thereby driving the rotation of the synchronous wheel 12; through the rotation of the synchronous wheel 12, the synchronous belt 7 is rotated accordingly, and with the help of the guiding effect of the guide wheel 14, the pull rod assembly 4 is driven to move up and down; the tension of the synchronous belt 7 is accurately adjusted by the pre-tensioning wheel 53 to ensure the stability and efficiency of the transmission; the up and down movement of the pull rod directly realizes the winding or unfolding function of the sunshade cloth; it is through the position sensor The sensor 115 monitors the position of the pull rod in real time, and the limit sensor 6 is triggered in time when the sunshade cloth reaches the limit position. The function of the sensor is to ensure that the movement of the sunshade cloth is carried out within the predetermined range to avoid damage or failure caused by excessive movement; it receives signals from the limit sensor 6 and the position sensor 115 through the main control component 8, and accurately controls the linear motor 111 and the electromagnetic clutch 113 according to these signals; the main control component 8 also transmits the state information of the sunshade cloth to the master control machine to realize remote monitoring of the sunshade system.
