TECHNICAL FIELD

[0001] The present application relates to the technical field of electric doors and windows, in particular to a hand drive seat of electric doors and windows. BACKGROUND

[0002] The electric door and window uses an electric motor as a power source to realize the automatic lifting of the window through the window glass lifter. A DC series motor with variable running direction is arranged in each door or near the window body. When the switch is pressed, the motor starts to run, and then the worm gear reducer installed on the main shaft of the motor drives the glass to slide up and down in parallel through the rotating drum and steel wire (or other transmission mechanism).

[0003] If the motor fails, the door and window cannot be driven, so a hand drive seat of electric doors and windows is needed. SUMMARY

[0004] In view of the deficiencies of the prior art, the purpose of the present application is to provide a hand drive seat of electric doors and windows to solve the problem that the door and window cannot be opened due to electric failure when the electric door and window is used.

[0005] The above purpose of the present application is achieved by the following technical scheme: a hand drive seat of electric doors and windows, comprising a manual drive seat arranged inside a window frame, a fan rotatably connected to the upper end of the window frame, passive lifting driven structures arranged on both sides of the fan, a bidirectional drive motor connected to one side of the manual drive seat, a drive rod rotatably connected to the inside of the window frame and fixedly arranged on the output end of one side of the bidirectional drive motor, the other end of the drive rod being connected to the manual drive seat, the manual drive seat comprising a connecting shell fixedly connected to one side of the bidirectional drive motor, a drive shaft rotatably arranged on the connecting shell, a drive bevel gear fixedly arranged at the bottom of the drive shaft, a transmission bevel gear fixedly arranged on the end of the bidirectional drive motor away from the drive rod, the transmission bevel gear being engaged with the drive bevel gear, a driven rod arranged on the side of the drive bevel gear away from the transmission bevel gear, a driving bevel gear fixedly arranged on the end of the driven rod close to the drive bevel gear, the driving bevel gear being engaged with the drive bevel gear, and driven bevel gears fixedly arranged on both ends of the driven rod and the drive rod for driving the driven structures on both sides.

[0006] By adopting the above technical scheme, the bidirectional drive motor is used as a common driving mode to drive the driven rod and the drive rod to rotate, thereby driving the driven structures on both sides to push the fan to open and close. When the bidirectional drive motor fails, the rotating drive shaft drives the drive bevel gear at the bottom to rotate, thereby rotating the driving bevel gear and the transmission bevel gear on both sides, so that the drive rods at both ends of the bidirectional drive motor drive the driven structures to realize manual window opening.

[0007] Further, the driving shaft is provided with a mounting shell, the mounting shell is rotationally connected with the driving shaft, the bottom of the mounting shell is fixedly connected with the connecting shell, the upper end of the driving shaft is fixedly provided with a driven gear, one side of the mounting shell is rotationally provided with a driving gear, the driving gear is engaged with the driven gear, and a driving hole is formed in the middle of the driving gear.

[0008] By adopting the above technical scheme, in order to more conveniently manually open the window, the driving hole starting from the middle of the driving gear is inserted and rotated by a special handle, the driven gear is rotated, and the driving shaft at the bottom is driven.

[0009] Further, the upper end of the driving hole is provided with a sealing cover mounted on the mounting shell.

[0010] By adopting the above technical scheme, when the manual driving device is not used, the driving hole is protected from foreign matter.

[0011] Further, the mounting shell is fixedly provided with an adsorbing magnet, and the sealing cover is inlaid with a placing magnet.

[0012] By adopting the above technical scheme, the placing magnet on the sealing cover and the adsorbing magnet on the mounting shell can stably connect the sealing cover to the mounting shell.

[0013] Further, the driven structure comprises rotating screws rotationally connected on both sides of the window frame, the rotating screws are fixedly provided with rotating bevel gears at the bottom, the rotating bevel gears are engaged with driving bevel gears, the rotating screws are slidingly provided with sliding blocks, the middle of the sliding blocks is provided with a rectangular slot, the rectangular slot is threadedly provided with a rotating nut, one side of the sliding block is rotationally provided with a linkage rod, and the other end of the linkage rod is rotationally connected with a fan.

[0014] By adopting the above technical scheme, after the driving bevel gears are driven by the rotating screws, the rotating screws are rotated, the rotating nut is pushed to slide, and the linkage rod is pushed to open the fan, so that the window is opened and closed.

[0015] Further, the lower end of the sliding block is provided with a locking block slidingly connected with the rotating screw, the middle of the locking block is provided with a driving nut threadedly connected with the rotating screw, connecting columns are inserted into both ends of the sliding block, the upper end of the connecting column is fixedly connected with a butt joint block, the butt joint block is slidingly connected with the rotating screw, the bottom of the connecting column is inserted into the locking block, and a buffer spring is sleeved on the rotating screw between the butt joint block and the sliding block.

[0016] By adopting the above technical scheme, when the fan is closed, the rotating screw drives the driving nut to reach the bottom, the spring drives the sliding block to the bottom through the rotating nut, and then the fan is closed.

[0017] Further, the bidirectional driving motor is provided with a support seat for supporting on both sides, and the support seat is fixedly connected inside the window frame.

[0018] Further, the sliding block and the locking block are fixedly provided with sliding bars on both sides.

[0019] By adopting the above technical scheme, the friction between the sliding block, the locking block and the window frame is reduced.

[0020] To sum up, the present application has the following beneficial technical effects: the user can choose to open or close the window quickly and easily in an electric mode, or can open or close the window manually through the manual transmission seat in the event of a power failure or the need for manual operation, thereby meeting the use requirements in different scenarios. Secondly, it enhances the reliability of the system, so that even if the electric system fails, the manual transmission seat as a backup driving mode can ensure the normal opening or closing of the window, thereby improving the safety and stability of the entire system. In addition, the application of bevel gear transmission system optimizes the transmission efficiency and reduces the loss in the energy transmission process, making the opening and closing of the window more rapid and smooth. At the same time, the design also takes into account the practicability and aesthetics, improving the user's experience. Finally, due to the reasonable structure design, the components are connected tightly and easy to disassemble, which is convenient for users to carry out daily maintenance and maintenance work, thereby prolonging the service life of the product.
