Description

Technical Field

[0001] This utility model relates to the field of electric windows, and more particularly to a sliding window. Background Technology

[0002] Current automatic windows mostly use a side-opening design, and the drive structure generally uses an electric cylinder. The two ends of the electric cylinder are hinged to the window body and the window frame, respectively. When the window is opened and closed, the electric cylinder moves with the window body. However, electric cylinders are not suitable for sliding windows because when sliding, the cylinder body needs to be perpendicular to the window body, which causes the cylinder body to extend backward, affecting the aesthetics and making installation inconvenient. Utility Model Content

[0003] The main purpose of this utility model is to provide a sliding window that can automatically open and close.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is: a sliding window, comprising:

[0005] Form;

[0006] A window frame is installed on the window body. The window frame is connected to the window body through a hinge connection mechanism. The window frame can move back and forth along a direction perpendicular to the plane where the window body is located to realize the opening and closing of the window.

[0007] The electrically driven assembly, located between the window frame and the window body, includes:

[0008] A first outer casing is disposed on the window and has an opening facing the window frame.

[0009] A chain, located inside the first housing, with one end extending from the opening to connect with the window frame, the chain extending outward from the opening to open the window or retracting from the opening to close the window.

[0010] Preferably, the chain is a double-chain chain, which includes a first chain and a second chain. One end of the first chain and the second chain passes through the opening and is connected to the same push head. The push head is located outside the first housing. The other ends of the first chain and the second chain are located inside the first housing. The first chain and the second chain located outside the first housing mesh with each other. The first chain and the second chain located inside the first housing are located on both sides of the opening. When the two chains are pushed out of the first housing, they mesh at the opening. When the two chains are retracted into the first housing, they separate at the opening.

[0011] Preferably, when the first chain and the second chain are pushed out into the first housing, the first chain and the second chain are engaged with each other and arranged in opposite directions. Both the first chain and the second chain include inner chain plates and outer chain plates. Adjacent inner chain plates and outer chain plates on the same chain are rotatably connected by a pin. The outer chain plates of the first chain and the outer chain plates of the second chain are staggered, so that the two ends of the outer chain plates of one chain can abut against the adjacent ends of two adjacent outer chain plates of the other chain.

[0012] Preferably, an abutment portion is formed on one side of each outer chain piece, and when the two chains are engaged, the abutment portions on the two chains abut against each other; the abutment portion has an abutment surface, which is arc-shaped and curved in a direction away from the other chain.

[0013] Preferably, the inner chain plates of the first chain and the second chain are staggered. The inner chain plates are provided with outwardly protruding fan-shaped portions. When the chain extends from the first outer shell, the fan-shaped portion on one chain extends toward the other chain. As the fan-shaped portion approaches the other chain, the size of the fan-shaped portion in the chain extension direction gradually increases. The fan-shaped portions on adjacent inner chain plates on the same chain form a fan-shaped space when the chain is straight. When the two chains mesh, the fan-shaped portion on one chain can be located in the corresponding fan-shaped space of the other chain, thereby achieving meshing.

[0014] Preferably, the fan-shaped portion includes an interference arc-shaped protrusion away from the body of the inner chain piece and an interference arc-shaped concave portion close to the body of the inner chain piece; the interference arc-shaped protrusion forms the outer arc top of the fan-shaped portion, and the interference arc-shaped concave portion forms the inner waist of the fan-shaped portion relative to the body of the inner chain piece; the interlocking interference arc-shaped protrusion and interference arc-shaped concave portion interfere with each other and fit together.

[0015] Preferably, the sliding window further includes a locking assembly, which includes a transmission plate that extends vertically on the window body, multiple locking pins arranged on the transmission plate in the vertical direction, and multiple locking plates disposed within the window frame. The locking pins and locking plates correspond one-to-one. The transmission plate is disposed on one side of the window body along the width direction of the window body, and the transmission plate can move vertically within a certain range. When the window is closed, the transmission plate moves vertically, enabling the locking pins to move to a position aligned with the corresponding locking plates in the moving direction of the window frame, and the locking pins are located on the side of the locking plates that blocks the window frame from opening, thereby achieving locking after the window is closed.

[0016] Preferably, the locking assembly further includes a manual unlocking assembly, which includes a second housing, the second housing being cuboid in shape and having an internal installation space. The second housing includes a cover with an opening on one side and a base plate detachably disposed at the opening.

[0017] Two racks and a gear are arranged within the installation space. The gear is rotatably mounted within the installation space, and its axis of rotation extends along the thickness direction of the outer shell and is collinear with the axis of the first through hole. The two racks extend along the length direction of the outer shell and move back and forth along the length direction. Both racks mesh with the gear and are symmetrically arranged relative to the axis of rotation of the gear. When the gear rotates, it can drive the two racks to move synchronously towards each other or away from each other. A transmission column is provided at the end of each rack away from the gear. When viewed along the length direction of the outer shell, the two transmission columns are aligned. A strip-shaped hole is provided on the side of the cover away from the bottom plate and at the position corresponding to the two transmission columns. The transmission columns pass through the corresponding strip-shaped hole and can move back and forth within the length range of the strip-shaped hole under the drive of the gear. Each transmission column is connected to the corresponding transmission plate through a flexible connector. The flexible connector is flexible and can bend to convert the horizontal movement of the transmission column into vertical movement.

[0033] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0034] A sliding window includes a window body 1 and a window frame 2 mounted on the window body 1. The window body 1 is fixed to a building. Glass is installed within the window frame 2. The window frame 2 is connected to the window body 1 via a hinge connection mechanism 3. The window frame 2 can move back and forth along a direction perpendicular to the plane of the window body 1 to achieve opening and closing of the window. The hinge connection mechanism 103 uses existing technology and will not be described in detail here.

[0035] Two electrically driven assemblies 4 are disposed between the window 1 and the window frame 2. The two electrically driven assemblies 4 have identical structures. Each electrically driven assembly 4 includes a first housing 410 and a double-chain disposed within the first housing 410. The double-chain includes a first chain 41 and a second chain 42. An opening is provided on the first housing 410. One end of the first chain 41 and the second chain 42 passes through the opening and is connected to the same push head 43. The push head 43 is located outside the first housing 410. The other ends of the first chain 41 and the second chain 42 are disposed inside the first housing 410. The first chain 41 and the second chain 42 located outside the first housing 410 are engaged with each other. The first chain 41 and the second chain 42 located inside the first housing 410 are respectively located on both sides of the opening. When the two chains are pushed out of the first housing 410, they engage at the opening. When the two chains are retracted into the first housing 410, they separate at the opening.

[0036] When the two chains are pushed into the first housing 410, the first chain 41 and the second chain 42 mesh with each other and are arranged in opposite directions. The first chain 41 and the second chain 42 each include an inner chain piece 4102 and an outer chain piece 4101. Adjacent inner chain pieces 4102 and outer chain pieces 4101 on the same chain are rotatably connected by a pin 4201. The outer chain pieces 4101 of the first chain 41 and the outer chain pieces 4101 of the second chain 42 are staggered, so that the two ends of the outer chain piece 4101 of one chain can abut against the close ends of two adjacent outer chain pieces 4101 of the other chain.

[0037] The inner chain plates 4102 of the first chain 41 and the second chain 42 are also staggered. Each inner chain plate 4102 has a protruding fan-shaped portion 41021. When the chain extends from the first outer shell 410, the fan-shaped portion 41021 on one chain extends towards the other chain. As the fan-shaped portion 41021 approaches the other chain, its size gradually increases in the chain extension direction. Adjacent inner chain plates 41021 on the same chain form a fan-shaped space when the chain is straight. When the two chains mesh, the fan-shaped portion 41021 on one chain can be located within the corresponding fan-shaped space of the other chain, thus achieving meshing. Due to the mutual abutment of the outer chain plates 4101 and the interlocking of the inner chain plates 4102 on the two chains, the meshing chains will not swing back and forth.

[0038] The sector-shaped portion 41021 includes an interference arc-shaped protrusion 41022 away from the body of the inner chain piece 4102 and an interference arc-shaped concave portion 41023 close to the body of the inner chain piece 4102. The interference arc-shaped protrusion 41022 forms the outer arc top of the sector-shaped portion 41021, and the interference arc-shaped concave portion 41023 forms the inner waist of the sector-shaped portion 41021 relative to the body of the inner chain piece 4102. The interlocking interference arc-shaped protrusion 41022 and interference arc-shaped concave portion 41023 interfere with each other and fit together. The contact portion of the interference arc-shaped protrusion 41022 and interference arc-shaped concave portion 41023 is a rounded transition structure. This rounded transition structure forms an interference contact surface when interlocked. The rounded transition structure makes the fastening smoother and easier, and also facilitates separation.

[0039] Chain drive mechanisms (not shown) are respectively provided at both ends inside the first housing 410. The output end of the chain drive mechanism is connected to the corresponding end of the chain located inside the first housing 10. The chain drive mechanism can push out or retract the chain. The chain drive mechanism can adopt the power mechanism disclosed in announcement number CN222558360U.

[0040] During installation, the first housings of the two electric drive components 4 are respectively installed on both sides of the window 1 along the width direction, and the push head 43 is installed on the window frame 2. The window frame 2 can be opened or closed by controlling the extension or retraction of the chain.

[0041] The sliding window also includes a locking assembly 5. When the chain-driven mechanism closes the window, the locking assembly 5 locks the window to prevent the frame from opening automatically. The locking assembly 5 has two sets with identical structures. Each set includes a transmission plate 51 extending vertically on the window body 1, multiple locking pins 52 arranged vertically on the transmission plate 51, and multiple locking plates 53 within the window frame 2. Each locking pin 52 corresponds to a locking plate 53. The transmission plates 51 of the two locking assemblies 5 are respectively located on both sides of the window body 1 along its width, and the transmission plates 51 can move vertically within their range of motion. When the window is closed, the transmission plates 5 move vertically, causing the locking pins 52 to align with the corresponding locking plates 53 in the direction of movement of the window frame 2. The locking pins 52 are positioned on the side of the locking plates 53 that prevents the window frame 2 from opening, thus locking the window after it is closed.

[0042] Furthermore, each of the locking components 5 also includes a driver 54 disposed on the corresponding side of the window 1. The output end of the driver 54 is connected to the corresponding transmission plate 51, and the output end of the driver 54 can move back and forth within a certain range in the vertical direction, thereby realizing locking and unlocking. The driver 54 adopts existing technology, and its principle is similar to that of a linear module.

[0043] Furthermore, the locking assembly also includes a manual unlocking assembly 6, which is suitable for use when electric unlocking is not possible, such as in the event of a power outage.

[0044] The manual unlocking assembly includes a second housing, which is cuboid in shape and has an internal installation space. The second housing includes a cover 61 with an opening on one side and a base plate 62 detachably disposed at the opening. A boss 611 is provided on the side of the cover 61 opposite to the base plate 62, and a first through hole 612 is provided on the boss 611.

[0045] Two racks 64 and a gear 63 are arranged within the installation space. The gear 63 is rotatably mounted within the installation space, and its axis of rotation extends along the thickness direction of the outer casing and is collinear with the axis of the first through hole 612. The two racks 64 extend along the length direction of the outer casing and move back and forth along the length direction. Both racks 64 mesh with the gear 63 and are symmetrically arranged relative to the axis of rotation of the gear 63. When the gear 63 rotates, it can drive the two racks 64 to move synchronously towards each other or away from each other. A transmission post 65 is provided at the end of each rack 64 away from the gear 63. When viewed along the length direction of the outer casing, the two transmission posts 65 are aligned. A strip-shaped hole 613 is provided on the side of the cover 61 away from the bottom plate 62 and at the position corresponding to the two transmission posts 65. The transmission post 65 passes through the corresponding strip-shaped hole 613 and can move back and forth within the length range of the strip-shaped hole 613 under the drive of the gear 63. Each of the transmission columns 65 is connected to the corresponding transmission plate 51 via a flexible connector 7. The flexible connector 7 is flexible enough to convert the horizontal movement of the transmission column 65 into vertical movement.

[0046] Preferably, the gear 63 is provided with a first operating hole 631. The cross-section of the first operating hole 631 is non-circular, preferably square. An operating handle or the like can be inserted into the first operating hole 631. The rotation of the gear 63 can be controlled by the operating handle, thereby controlling the movement of the transmission column 65. The operating handle is detachable and can be removed when manual operation is not required. In the event of a power outage or other situations, the window can be opened or closed by operating the operating handle.

[0047] Preferably, a second through hole 621 is provided on the base plate 62 at a position corresponding to the first operating hole 631. The axis of the second through hole 621 is collinear with the axis of the first through hole 612, and both have the same diameter. The two ends of the gear 3 are respectively inserted into the first through hole 612 and the second through hole 621, which can limit the movement of the gear 63.

[0048] Furthermore, in the thickness direction of the outer casing, the size of the rack 64 is equal to the size of the mounting space, meaning the rack 64 will not wobble in the thickness direction. Preferably, in the thickness direction, the side of the rack 64's tooth groove closest to the base plate 62 is blocked, the size of the teeth on the gear 63 is equal to the size of the tooth groove on the rack 64, and the side of the rack 64's tooth groove furthest from the base plate 62 is blocked by the cover 61, meaning the gear 64 is limited in the thickness direction by the rack 64 and the cover 61.

[0049] Preferably, a slot 614 is provided between the boss 611 and the cover 61 on both sides along the width direction of the cuboid. The slot 614 extends through the boss 611 along the length direction. Two threaded holes 615 are provided on the boss 611, symmetrically arranged with respect to the axis of the first through hole 612. A bolt 617 is provided in each threaded hole 615. A third through hole 616 is provided on the base plate 62 at the position corresponding to each threaded hole 615, allowing the bolt 617 to be operated. During installation, an inverted T-shaped groove is formed at the installation position of the door or window. The boss 611 can be placed in the T-shaped groove, and the cross-section of the T-shaped groove matches the cross-section of the boss 611. The upper sidewall of the T-shaped groove can be inserted into the slot 614. By tightening bolt 617, the end face of bolt 617 can abut against the bottom of the T-slot, thereby achieving a fixed connection between the unlocking actuator and the door / window.

[0050] Preferably, two second operating holes 617 are also provided on the boss 611, and the two second operating holes 617 are symmetrically arranged with respect to the axis of the first through hole 612. Two third operating holes 622 are provided on the base plate 62, and the two third operating holes 622 are aligned with the two second operating holes 617 one by one. In practice, there will be bolts or other components on the doors and windows at the positions corresponding to the second operating holes 617. The second operating holes 617 and the third operating holes 622 facilitate the operation of the corresponding structures on the doors and windows.
