Description

A manual / automatic emergency drive device for an electric lift window motor Technical Field

[0001] This invention relates to the field of electric lift window accessories, and in particular to an emergency drive device for an electric lift window motor that integrates manual and automatic operation. Background Technology

[0002] Electric lift windows have become a mainstream product in the door and window industry due to their convenient operation and suitability for large windows with solid glass panels. They mainly consist of a window frame, a fixed window, a movable window, and a drive motor. The movable window is driven by the drive motor to achieve vertical sliding opening and closing. Especially for large windows with solid glass panels, it can effectively replace manual labor to complete the lifting and lowering operation of heavy windows, greatly improving the convenience of use.

[0003] In practical use, the drive motor of the electric lift window relies on electricity. In the event of a sudden power outage, a backup power supply is sufficient to power the motor for normal opening and closing. However, when the electrical control system malfunctions, even with a backup power supply, the motor cannot be driven. In this case, the drive motor will be completely unable to work, and the movable window will be in a fixed state, unable to open or close, causing great inconvenience to the user. Some existing technologies only equip the electric lift window with a backup power supply. This type of backup power supply needs to power the entire motor drive, which consumes a lot of energy, requires frequent charging or battery replacement, and cannot solve the window opening and closing problem caused by electrical control system failure. At the same time, the setting of a high-power backup power supply also significantly increases the cost of use and maintenance.

[0004] To address the aforementioned issues, existing technologies have introduced solutions that equip the motor drive of electric lift windows with a manual emergency mechanism. For example, the lift window lifting control device with patent publication number CN116480245A connects the manual shaft with a gear transmission assembly to the motor shaft, enabling manual drive of the motor shaft to rotate and raise / lower the window. This eliminates the need for a high-power backup power supply for the motor drive, reducing some operating costs. However, such manual emergency mechanisms have significant drawbacks: First, the manual transmission assembly and motor shaft are constantly connected without a disengagement mechanism. In electric drive mode, the rotation of the motor shaft synchronously drives the manual shaft and transmission assembly, which can easily cause wear and damage to the manual shaft over time, significantly reducing the service life of the manual mechanism. Second, some simple manual emergency mechanisms directly drive the motor shaft by external force, lacking a brake, unlock, and torque matching structure. During manual drive, excessive torque can easily damage the internal transmission structure of the motor, causing motor failure. Third, in some manual mechanisms, the brake unlock and manual drive actions are performed in separate steps, resulting in low operational efficiency in emergency situations and an inability to quickly adjust the opening and closing of the window.

[0005] In addition, electric lift windows are mostly used in building doors and windows, which require high structural compactness and installation compatibility of accessories. Some existing emergency manual mechanisms of motors are large in size and complex in structure, making it difficult to adapt to the miniaturized drive motor of electric lift windows. Furthermore, their insulation and wear resistance are poor, which can easily lead to failure after long-term use, affecting the overall performance of electric lift windows.

[0006] To address the shortcomings of existing technologies, the development of a compact, electric lift window drive motor that can simultaneously engage brake unlocking and emergency drive in response to electronic control system malfunctions, while also enabling the manual drive structure to disengage from the motor shaft to prevent damage to the motor and manual components, and requiring only a low-power backup power supply for brake unlocking, has become a pressing technical problem in this field. Summary of the Invention

[0007] To address the shortcomings of existing technologies, this invention provides a manual / automatic emergency drive device for electric lift window motors. This device solves the core problem that existing emergency mechanisms for electric lift window motors cannot handle the failure of backup power to drive the motor when the electrical control system malfunctions. It also overcomes the defects of existing manual emergency mechanisms, such as easy wear and tear, easy motor failure caused by direct drive, asynchronous brake unlocking and manual drive, and poor structural adaptability.

[0008] To achieve the above objectives, the present invention provides a manual / automatic emergency drive device for an electric lift window motor, comprising a housing, an emergency drive transmission mechanism, a brake unlocking conductive mechanism, and an elastic reset mechanism.

[0009] The emergency drive transmission mechanism is located inside the housing and is used to transmit torque in an emergency to drive the rotating shaft of the electric lifting window drive motor to rotate, thereby driving the movable window of the electric lifting window to rise and fall.

[0010] The brake unlocking conductive mechanism is located inside the housing of the device and is linked with the emergency drive transmission mechanism. When the emergency drive transmission mechanism is activated, it can conduct the electrical circuit to release the brake of the electric lifting window drive motor, thus avoiding damage to the motor due to excessive torque during manual drive.

[0011] The elastic reset mechanism is located inside the housing and connected to the brake unlocking conductive mechanism. It is used to drive the brake unlocking conductive mechanism and the emergency drive transmission mechanism to reset after the emergency drive is completed, so that the manual drive structure is disengaged from the motor shaft and the electrical circuit of brake unlocking is disconnected, ensuring that the manual component does not move when the motor is normally driven.

[0012] Furthermore, the housing includes a motor rear housing fixedly connected to the electric lifting window drive motor and a device housing fixedly disposed on the rear side of the motor rear housing.

[0013] Furthermore, the emergency drive transmission mechanism includes a motor tail shaft, an adapter, a drive shaft, and a sliding bushing. The motor tail shaft is located inside the rear housing of the motor, with its front end connected to the transmission structure of the electric lifting window drive motor and its rear end connected to the adapter. The rear end of the adapter has a hexagonal slot, and the rear side of the device housing has a through slot. The sliding bushing is fitted into the through slot, and the drive shaft passes through the sliding bushing and slides along its axial direction. Pushing the drive shaft allows its front end to be inserted into the hexagonal slot to achieve torque transmission. After resetting, the drive shaft disengages from the adapter to prevent the drive shaft from rotating when the motor is electrically driven.

[0014] Furthermore, the brake unlocking conductive mechanism includes a first conductive spring, a second conductive spring, a conductive contact plate, and an insulating sleeve. The first and second conductive springs are fixed to the inner wall of the device housing, and the insulating sleeve is disposed between the drive shaft and the conductive contact plate, so that the two are linked and electrically isolated. Pushing the drive shaft can drive the conductive contact plate to move synchronously and contact the first and second conductive springs, thereby realizing the conduction of the brake unlocking electrical circuit and effectively preventing current from being conducted to the drive shaft, ensuring electrical safety.

[0015] Furthermore, the rear end of the drive shaft extends to the outside of the device housing, and this end is provided with a hexagonal operating groove adapted to hexagonal tools, which can be adapted to tools such as manual hexagonal screwdrivers and electric hexagonal screwdrivers to meet the operational needs of different emergency scenarios. Moreover, the operation method is simple, no professional tools are required, and it is convenient for users to operate quickly.

[0016] Furthermore, the elastic reset mechanism is a reset compression spring, with one end of the reset compression spring abutting against the conductive contact plate and the other end abutting against the rear housing of the motor. The elastic driving force is stable, which can realize the reliable reset of the conductive contact plate and the drive shaft. The structure is simple and easy to maintain.

[0017] Furthermore, both the first and second conductive springs are fixedly connected to the inner wall of the device housing by fastening bolts, ensuring a firm connection and stable contact between the conductive springs and the conductive contact plate, thus ensuring reliable conduction of the brake unlocking electrical circuit.

[0018] Furthermore, the insulating sleeve is rotatably mounted on the drive shaft via a bearing. A positioning part is protruding from the end of the insulating sleeve, and the conductive contact plate is rotatably connected to the positioning part. A through hole is provided on the conductive contact plate. The outer diameter of the insulating sleeve body is larger than the diameter of the through hole, and the outer diameter of the positioning part is smaller than the diameter of the through hole. The positioning part is inserted into the through hole. This structure not only provides axial positioning for the conductive contact plate to prevent it from shifting, but also overcomes the elastic force of the reset compression spring on the conductive contact plate, ensuring the stability of the axial linkage between the two. Moreover, the insulating sleeve can rotate relative to the conductive contact plate when the drive shaft rotates, without friction or wear.

[0019] Furthermore, a spring sleeve is integrally provided on the side of the conductive contact plate facing the rear housing of the motor. The spring sleeve is used to position the reset compression spring, prevent the reset compression spring from shifting or getting stuck during the extension and retraction process, and ensure the smoothness of the reset action.

[0020] Furthermore, an insulating washer is provided on the side of the motor rear housing facing the device housing, and the end of the reset compression spring away from the conductive contact plate abuts against the insulating washer to prevent the current on the conductive contact plate from being conducted to the motor rear housing through the reset compression spring, thereby further improving the insulation performance of the device and adapting to the environmental requirements of building doors and windows.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] 1. Precisely addresses the core pain points of electrical control system failures, while also accommodating sudden power outage scenarios: This device addresses the issue of backup power being unable to drive the motor during electrical control system failures by achieving synchronized mechanical emergency drive and brake unlocking, enabling rapid window opening and closing. Simultaneously, the device is adaptable to sudden power outage scenarios, with a unified operation method, significantly improving the versatility and reliability of emergency use. After reset, the drive shaft and adapter are completely disengaged, and the manual components will not move when the motor is in normal electric drive mode. This completely solves the wear and damage problems caused by the constant connection between the existing manual mechanism and the motor shaft, extending the service life of both the motor and the manual mechanism.

[0023] 2. Synchronized Brake Unlocking and Emergency Drive for Motor Protection and High Efficiency: The brake unlocking conductive mechanism and the emergency drive transmission mechanism are linked. During the forward push of the drive shaft, the conductive contact plate and conductive spring can simultaneously complete the contact and conduction, motor brake unlocking, and the insertion and engagement of the drive shaft and adapter. No step-by-step operation is required, and the window can be quickly opened and closed in an emergency. At the same time, after the motor brake is unlocked, the torque resistance during manual drive is greatly reduced, avoiding damage to the internal transmission structure of the motor caused by direct hard drive of the motor, effectively protecting the drive motor of the electric lifting window.

[0024] 3. Compact structure, compatible with electric lift window motor: This device is installed at the tail of the electric lift window drive motor. All mechanisms are integrated into the housing. It is small in size and compact in structure. It can be adapted to the miniaturized drive motor of electric lift window. The installation method is simple. It is fixed to the rear housing of the motor by connecting bolts. There is no need to make major modifications to the motor body. It has strong adaptability.

[0025] 4. Simple operation, low backup power consumption, and easy maintenance: The drive shaft end has a hexagonal operating slot, which can be used with common tools such as ordinary manual hex screwdrivers. Users can operate quickly in emergency situations such as power outages without the need for professional tools. The backup power of this device only supplies power for motor brake unlocking and does not need to supply power for motor drive. The energy consumption is extremely low, and there is no need for frequent charging or battery replacement, which greatly reduces the difficulty of maintenance and the cost of use. It solves the problem of cumbersome maintenance and high cost of existing high-power backup power supplies.

[0026] 5. Wear-resistant and insulating, suitable for building door and window use environment: The sliding bushing is embedded at the joint between the drive shaft and the device housing, which uses its self-lubricating properties to reduce friction and wear, and achieve maintenance-free use; at the same time, a double insulation structure of insulating isolation sleeve and insulating gasket is set to effectively prevent current conduction, ensure electrical safety, and adapt to complex outdoor and humid use environments of building doors and windows, thereby improving the reliability and service life of the device.

[0027] 6. Reliable reset, ensuring long-term stable use of the device: The conductive contact plate is equipped with an integrated spring sleeve to accurately position the reset compression spring, preventing spring offset and jamming. This ensures that after the emergency drive is completed, the conductive contact plate can reliably reset and disconnect the brake unlocking circuit, and the drive shaft can be completely disengaged from the adapter. This ensures that the device does not affect the normal operation of the motor in non-emergency situations and can be used without failure for a long time. Attached Figure Description

[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] This invention discloses a manual / automatic emergency drive device for an electric lift window motor. The device is installed at the tail of the electric lift window drive motor without requiring major structural modifications to the motor body. It is also adapted to the installation requirements of miniaturized electric lift window drive motors. The core function is to provide emergency drive for electrical control system failures, while also taking into account sudden power outage scenarios.

[0036] As shown in Figures 1-5, this device includes a housing 1, an emergency drive transmission mechanism 2, a brake unlocking conductive mechanism 3, and an elastic reset mechanism 4. The housing 1 serves as the foundation for the installation and protection of the entire device. It includes a motor rear housing 11 integrally formed with the electric lifting window drive motor and a device housing 12 fixed to the rear side of the motor rear housing 11. The device housing 12 and the motor rear housing 11 are symmetrically fixedly connected by multiple sets of connecting bolts, forming a sealed installation cavity. An insulating washer 5 is bonded and fixed to the side of the motor rear housing 11 facing the device housing 12. The insulating washer 5 is made of high-temperature resistant and aging-resistant epoxy insulating plastic, suitable for outdoor and humid environments of building doors and windows.

[0037] The emergency drive transmission mechanism 2 is located in the mounting cavity of the housing 1, and includes a motor tail shaft 21, an adapter 22, a drive shaft 23, and a sliding bushing 24. The motor tail shaft 21 is located inside the rear housing 11 of the motor, with its front end fixedly connected to the rotor and internal transmission structure of the electric lifting window drive motor, and its rear end inserted into the adapter 22 and fastened by set screws on the side wall of the adapter 22 to achieve stable torque transmission. The rear end of the adapter 22 has an internal hexagonal groove 221, and a corresponding through groove 121 is provided on the rear side of the housing 12. The sliding bushing 24... The self-lubricating integrated sleeve structure is made of graphite copper and is interference-fitted into the inner wall of the through groove 121. The drive shaft 23 passes through the sliding bushing 24 and forms an axial sliding fit with the sliding bushing 24. Utilizing the self-lubricating properties of the sliding bushing 24, the friction loss between the drive shaft 23 and the device housing 12 during axial sliding and circumferential rotation is effectively reduced, and no additional lubricant is required, achieving maintenance-free use. The rear end of the drive shaft 23 extends to the outside of the device housing 12, and this end is provided with a hexagonal operating groove 231 adapted to hexagonal tools. It is compatible with common tools such as ordinary manual hexagonal screwdrivers and electric hexagonal screwdrivers. When the drive shaft 23 is pushed forward, its front end can be precisely fitted into the hexagonal groove 221 of the adapter 22 to achieve torque transmission and docking between the two. After resetting, it is completely disengaged, preventing the drive shaft 23 from moving when the motor is electrically driven.

[0038] The brake unlocking conductive mechanism 3 is located inside the device housing 12 and forms an axial linkage with the emergency drive transmission mechanism 2. It includes a first conductive spring 31, a second conductive spring 32, a conductive contact plate 33, and an insulating sleeve 34. The first conductive spring 31 and the second conductive spring 32 are both made of highly elastic conductive copper sheets and are symmetrically fixed to the inner wall of the device housing 12 by fastening bolts 35. They are electrically connected to the backup power supply terminal of the electric lifting window drive motor and the motor brake coil, respectively. The insulating sleeve 34 is rotatably fitted onto the middle position of the drive shaft 23 by a deep groove ball bearing. Its end near the conductive contact plate 33 is integrally formed into a cylindrical positioning part 341. The conductive contact plate 33 is a conductive metal disc structure with a corresponding circular through hole. The outer diameter of the main body of the insulating sleeve 34 is larger than the diameter of the through hole, and the outer diameter of the positioning part 341 is smaller than the diameter of the through hole. The positioning part 341 is inserted into the through hole with a gap, realizing the connection between the insulating sleeve 34 and the conductive contact plate 33. The structure provides a rotating connection; on the one hand, it axially positions the conductive contact plate 33 to prevent radial displacement during linkage; on the other hand, it utilizes the stepped surface formed by the main body of the insulating sleeve 34 and the edge of the through hole to effectively overcome the elastic force of the reset compression spring on the conductive contact plate 33, ensuring the stability of the axial linkage between the insulating sleeve 34 and the conductive contact plate 33; at the same time, the insulating sleeve 34 completely electrically isolates the drive shaft 23 from the conductive contact plate 33, preventing current from being conducted to the drive shaft 23; when the drive shaft 23 is pushed forward, the drive shaft 23 can drive the conductive contact plate 33 to move forward synchronously along the axial direction through the insulating sleeve 34, so that the conductive contact plate 33 makes close contact with the first conductive spring 31 and the second conductive spring 32 at the same time, thereby conducting the electrical circuit for unlocking the motor brake.

[0039] The elastic reset mechanism 4 is a cylindrical helical reset compression spring, located in the mounting cavity of the housing 1. One end of the spring abuts against the side of the conductive contact plate 33 facing the motor rear housing 11, and the other end abuts against the insulating washer 5 on the motor rear housing 11. A cylindrical spring sleeve 331 is integrally formed on the side of the conductive contact plate 33 facing the motor rear housing 11. The end of the reset compression spring is sleeved on the outside of the spring sleeve 331. The spring sleeve 331 provides radial precision positioning of the reset compression spring, preventing it from shifting, tilting, or jamming during extension and retraction, thus ensuring the smoothness and reliability of the reset action. At the same time, the insulating washer 5 can effectively block the current on the conductive contact plate 33 from being conducted to the motor rear housing 11 through the reset compression spring, forming a double insulation protection of the insulating sleeve 34 and the insulating washer 5, thereby improving the overall electrical safety performance of the device.

[0040] The working process of this invention includes two stages: emergency drive operation and reset recovery operation, adapting to emergency scenarios such as electric lift window control system failure and sudden power outage:

[0041] Emergency Drive Operation: When the electric lift window fails to operate due to a malfunction in the electrical control system or a sudden power outage, and the window is in a fixed state requiring adjustment, the operator inserts the tip of a standard hex screwdriver into the hexagonal operating slot 231 at the rear end of the drive shaft 23, and pushes the drive shaft 23 forward axially. The drive shaft 23 slides axially along the sliding bushing 24, and its front end gradually inserts into the hexagonal slot 221 of the adapter 22, achieving torque transmission connection between the drive shaft 23 and the adapter 22. Simultaneously, the drive shaft 23 is driven by the insulating sleeve 34. The conductive contact plate 33 moves forward synchronously, pressing the reset compression spring forward, causing the reset compression spring to elastically contract until the conductive contact plate 33 makes tight contact with the first conductive spring 31 and the second conductive spring 32, thus completing the closed electrical circuit of motor backup power supply terminal → first conductive spring 31 → conductive contact plate 33 → second conductive spring 32 → motor brake coil → motor backup power supply terminal. The motor brake coil is energized and generates magnetic force, which releases the brake structure of the electric lifting window drive motor, greatly reducing the torque resistance of manual drive.

[0042] At this time, the operator turns the hex screwdriver, causing the drive shaft 23 to rotate circumferentially. The drive shaft 23, through the cooperation of the hexagonal slot 221 and the adapter 22, transmits the torque sequentially to the adapter 22 and the motor tail shaft 21. Through the internal transmission structure of the motor, it drives the motor rotating shaft to rotate, thereby driving the movable window of the electric lifting window to complete the lifting action and realize emergency opening and closing adjustment. During this process, the drive shaft 23 rotates circumferentially, and the insulating sleeve 34 rotates synchronously with the drive shaft 23 under the action of the bearing, avoiding friction and wear with the conductive contact plate 33, while ensuring the electrical contact stability between the conductive contact plate 33 and the two conductive springs.

[0043] Reset and recovery operation: When the electric lifting window is adjusted to the target position, or after the power supply or electrical control fault is cleared, the operator releases the axial thrust on the drive shaft 23. The reset compression spring begins to extend under its own elastic restoring force, pushing the conductive contact plate 33 to move backward axially. The conductive contact plate 33 drives the drive shaft 23 to reset synchronously backward through the insulating isolation sleeve 34 until the conductive contact plate 33 completely disengages from the first conductive spring 31 and the second conductive spring 32, disconnecting the electrical circuit for unlocking the brake. The motor brake coil is de-energized, the brake structure automatically resets, and the motor returns to normal braking state.

[0044] At the same time, the front end of the drive shaft 23 is completely disengaged from the hexagonal slot 221 of the adapter 22, and the torque transmission between the two is disconnected. The entire emergency drive transmission mechanism 2 returns to its initial state. When the motor is driven normally in the future, the drive shaft 23 and the related manual operation components will not move, avoiding wear and damage to the components and causing no interference to the electric drive of the motor. The device returns to the standby state, waiting for the next emergency use.

[0045] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
