[0008] Preferably, the first transmission seat includes a locking member slide rail that restricts the sliding direction of the second locking member and swing arm mounting positions at both ends of the locking member slide rail. The other end of the secondary swing arm and one end of the secondary auxiliary swing arm are rotatably connected to the corresponding swing arm mounting positions. The two swing arm mounting positions are higher than the locking member slide rail, so that a recessed space matching the first locking member and the second locking member is formed between the two swing arm mounting positions and the locking member slide rail.

[0009] Preferably, the transmission assembly includes a transmission bar, a first transmission connection position, and a second transmission connection position. The first transmission connection position and the second transmission connection position are respectively fixed to both ends of the transmission bar. The first transmission seat and the second transmission seat are respectively provided with transmission bar slide rails. The two transmission bar slide rails are connected to each other, and the transmission bar is slidably connected to the two transmission bar slide rails.

[0010] Preferably, the transmission bar slide rail is disposed on one surface of the first transmission seat, the locking member slide rail is disposed on the other surface of the first transmission seat, the first transmission seat is also provided with a locking member limiting hole, one end of the second locking member is fixed to the transmission bar, and the other end of the second locking member extends out of the locking member limiting hole and slides on the locking member slide rail.

[0011] Preferably, the first locking element is a locking groove, and the second locking element is a locking head; or, the first locking element is a locking head, and the second locking element is a locking groove; after the locking head slides into the locking groove, the swing arm assembly is locked.

[0012] Preferably, the locking groove includes an inlet portion, a locking portion, and an outlet portion. The inlet portion and the outlet portion are symmetrically arranged at both ends of the locking portion. Both the inlet portion and the outlet portion are wedge-shaped grooves, and the opening width of the wedge-shaped groove is greater than the width of the locking portion.

[0014] The beneficial effects of this invention are as follows:

[0015] The swing arm transmission device in this solution connects both the swing arm assembly and the transmission assembly to a transmission connecting frame, forming a swing arm transmission device that can be independently manufactured, installed, and transported. By fixing the transmission connecting frame to the window sash, the swing arm assembly 20 and the transmission assembly 30 can be simultaneously connected to the window sash 300, eliminating the need for separate installation of the swing arm assembly and transmission assembly on the window sash, thus facilitating installation and saving profiles and space. Simultaneously, a first locking element is located on the swing arm assembly, and a second locking element is located on the transmission assembly, allowing direct control of the swing arm assembly's fixation at the upper or lower edge of the window sash via an operating handle. This solution integrates the angle actuator and the swing arm hinge device into a single swing arm transmission device, simplifying the product structure, reducing production and installation steps and time, while also adding a locking function to the swing arm assembly, improving product performance, and expanding the applicability of the transmission device.

[0033] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0034] In the description of this invention, it should be noted that the terms "center," "upper," "lower," "left," "right," "front," "rear," "vertical," "horizontal," "inner," and "outer," etc., indicating orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention; the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance; furthermore, unless otherwise explicitly specified and limited, the terms "installed," "connected," and "linked" should be interpreted broadly, for example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium, or they can refer to the internal communication of two components. For those skilled in the art, the specific meaning of the terms in this invention can be understood according to the specific circumstances.

[0035] See Figure 1 This embodiment discloses a window, including a window frame 200, a window sash 300, and a swing arm transmission device 100. One end of the swing arm transmission device 100 is fixed to the two vertical sides of the window sash 300, and the other end of the swing arm transmission device 100 is connected to the window frame 200. Specifically, the swing arm transmission device 100 is applied to a window that can be pushed open or tilted inward.

[0036] See further Figure 2-10 The swing arm transmission device 100 includes a transmission connecting frame 10, a swing arm assembly 20, a transmission component 30, and a locking component 40. The transmission connecting frame 10 includes a first transmission seat 11 and a second transmission seat 12, which are respectively fixed to the vertical sides of the window sash 300. One end of the swing arm assembly 20 is rotatably connected to the first transmission seat 11, and the other end of the swing arm assembly 20 is used to connect to the window frame 200. The transmission component 30 is connected to the operating handle and passes through the first transmission seat 11 and the second transmission seat 12. The locking component 40 includes a first locking member 41 and a second locking member 42. The first locking member 41 is fixed to the swing arm assembly 20, and the second locking member 42 is fixed to the transmission component 30 and slides within the first transmission seat 11. When the first locking member 41 and the second locking member 42 are matched, the first locking member 41 cannot move, and the swing arm assembly 20 is locked.

[0037] Compared to existing technologies, the swing arm transmission device 100 in this solution connects both the swing arm assembly 20 and the transmission assembly 30 to the transmission connecting frame 10, forming a swing arm transmission device that can be independently manufactured, installed, and transported. Fixing the transmission connecting frame 10 to the window sash 300 simultaneously connects the swing arm assembly 20 and the transmission assembly 30 to the window sash 300, eliminating the need for separate installations of the swing arm assembly 20 and the transmission assembly 30 on the window sash 300, simplifying installation and saving profiles and space. Furthermore, the first locking member 41 is located on the swing arm assembly 20, and the second locking member 42 is located on the transmission assembly 30, allowing direct control of the swing arm assembly 20's fixation to the upper or lower edge of the window sash 300 via an operating handle. This solution integrates the angle actuator and the swing arm hinge device into a single swing arm transmission device 100, simplifying the product structure, reducing production and installation time, and adding a locking function to the swing arm assembly 20, thereby improving product performance and expanding the applicability of the transmission device.

[0038] It should be noted that the transmission component 30 passes through the first transmission seat 11 and the second transmission seat 12. The transmission component 30 is connected to the operating handle to input operating power, so as to control the opening or closing of the window sash 300 and the window frame 200 through the lock head and lock seat structure at the position where the window sash 300 contacts the window frame 200.

[0039] Meanwhile, the first locking member 41 is fixed on the transmission assembly 30 and located in the first transmission seat 11, so that the transmission assembly 30 can control the first locking member 41 and the second locking member 42 to match and lock the swing arm assembly, thus meeting the transmission requirements of window types such as sliding windows, tilt-and-turn windows and sliding-and-tilt windows.

[0040] In this embodiment, the swing arm assembly 20 includes a primary swing arm 21 and a secondary swing arm 22. One end of the primary swing arm 21 is rotatably connected to the window frame 200, and the other end of the primary swing arm 21 is rotatably connected to one end of the secondary swing arm 22. The other end of the secondary swing arm 22 is connected to the first transmission seat 11, and the first locking member 41 is provided on the secondary swing arm 22.

[0041] It should be noted that the swing arm assembly 20 is located above the window sash 300. The upper primary swing arm 21 is identical to the lower swing arm structure of the window sash 300, and is used to cooperate with the lower swing arm of the window sash 300 to achieve the parallel extension of the window sash 300. After both the upper primary swing arm 21 and the lower swing arm structure of the window sash 300 are extended, the window sash 300 and the window frame 200 are parallel to each other, which can facilitate further translation of the window sash 300. The secondary swing arm 22 extends the hinge length above the window sash 300. When the lower swing arm structure is locked, both the secondary swing arm 22 and the primary swing arm 21 are extended, and the window sash 300 tilts against the window frame 200, and the window sash 300 is in an inward tilting state.

[0042] By mounting the first locking member 41 on the secondary swing arm 22, it is ensured that the secondary swing arm 22 cannot move when the operating handle locks the second locking member 42 within the first locking member 41. This prevents the window sash 300 of the sliding tilt-in window from tilting inwards during the sliding process. It should be noted that when the operating handle is rotated to the sliding position of the window sash 300, the transmission assembly 30 causes the locking limit point between the window sash 300 and the window frame 200 to separate from the lock seat, allowing the window sash 300 to detach from the window frame 200. Driven by the transmission assembly 30, the first locking member 41 and the second locking member 42 match, locking the second swing arm 22. The locking of the second swing arm 22 and the separation of the window sash 300 from the window frame 200 occur simultaneously, eliminating the need for two steps and saving operational steps.

[0043] In this embodiment, the swing arm assembly 20 further includes a secondary auxiliary swing arm 23 and a secondary auxiliary rotating shaft 24. One end of the secondary auxiliary swing arm 23 is rotatably connected to the first transmission seat 11, and the other end of the secondary auxiliary swing arm 23 is provided with a locking member sliding groove 231. One end of the secondary auxiliary rotating shaft 24 is rotatably connected to the secondary swing arm 22, and the other end of the secondary auxiliary rotating shaft 24 slides within the locking member sliding groove 231. The secondary auxiliary swing arm 23 is used to support the secondary swing arm 22, preventing one end of the secondary swing arm 22 from deforming under the pressure of the primary swing arm 21, thereby preventing the secondary swing arm 22 from retracting into the window frame 200. The locking member sliding groove 231 is provided to limit the rotation angle of the secondary auxiliary swing arm 23, so as to better cooperate with the functional realization of the secondary swing arm 22.

[0044] In this embodiment, the first locking member 41 is provided with a locking slider 411 that is adapted to the locking member sliding groove 231. The first locking member 41 is fixed on the secondary auxiliary rotating shaft 24, and the locking slider 411 is limited to the locking member sliding groove 231 to slide along the opening direction of the locking member sliding groove 231. The locking slider 411 is integrally formed with the first locking member 41, and the two ends of the locking slider 411 are slidably connected to the two side walls of the locking member sliding groove 231. The setting of the locking slider 411 further restricts the position and direction of the first locking member 41, preventing the first locking member 41 from rotating or deviating during the rotation of the secondary auxiliary swing arm 23, and ensuring the matching accuracy between the first locking member 41 and the second locking member 42.

[0045] In this embodiment, the first transmission seat 11 includes a locking member slide rail 111 that restricts the sliding direction of the second locking member 42, and swing arm mounting positions 112 located at both ends of the locking member slide rail 111. The other end of the secondary swing arm 22 and one end of the secondary auxiliary swing arm 23 are rotatably connected to the corresponding swing arm mounting positions 112. The two swing arm mounting positions 112 are higher than the locking member slide rail 111, so that a recessed space 401 matching the first locking member 41 and the second locking member 42 is formed between the two swing arm mounting positions 112 and the locking member slide rail 111. It can be understood that the second locking member 42 is located on the first transmission seat 11 and the first locking member 41 is located below the secondary auxiliary swing arm 23 to ensure that the secondary swing arm 22, the secondary auxiliary swing arm 23 and the first transmission seat 11 will not interfere with each other during the rotation of the first locking member 41 and the sliding of the second locking member 42.

[0046] In this embodiment, the transmission assembly 30 includes a transmission bar 31, a first transmission connection position 32, and a second transmission connection position 33. The first transmission connection position 32 and the second transmission connection position 33 are respectively fixed to both ends of the transmission bar 31. Transmission bar slide rails 113 are respectively provided in the first transmission seat 11 and the second transmission seat 12. The two transmission bar slide rails 113 are interconnected, and the transmission bar 31 is slidably connected within the two transmission bar slide rails 113. It can be understood that the first transmission connection position 32 is used to connect the transmission belt located at the upper edge of the window sash 300, and the second transmission connection position 33 is used to connect the transmission belt located at the side edge of the window sash 300. The transmission assembly 30 can further drive the transmission operation of other transmission belts.

[0047] Understandably, the transmission component 30 of this solution can function as an angle actuator, which is constructed by housing a strip-shaped component inside the housing. The housing is L-shaped with a pair of guide sections along the length of the horizontal and vertical frames, and the guide passages on each guide section are connected by an arc-shaped connecting passage. The strip-shaped component is made of a flexible metallic sheet and can be slidably disposed in the guide passages and connecting passages covering the guide sections. At the ends of the strip-shaped component, connecting components are connected via sliders. Since the two connecting components are connected by the strip-shaped component, if the operating handle is operated, the connecting components on the horizontal frame and the connecting components on the vertical frame slide in conjunction, and the connection state of the linkage and locking mechanism also switches in conjunction, allowing the door / window sash to switch between an inward-opening state and an inward-folding state relative to the opening frame.

[0048] In this embodiment, the transmission bar slide rail 113 is disposed on one surface of the first transmission seat 11, and the locking member slide rail 111 is disposed on the other surface of the first transmission seat 11. The first transmission seat 11 is also provided with a locking member limiting hole 114. One end of the second locking member 42 is fixed to the transmission bar 31, and the other end of the second locking member 42 extends out of the locking member limiting hole 114 and slides on the locking member slide rail 111. Specifically, the transmission bar slide rail 113 is disposed on the upper surface of the first transmission seat 11, and the locking member slide rail 111 is disposed on the lower surface of the first transmission seat 11. The locking member limiting hole 114 is provided to limit the sliding trajectory of the second locking member 42, which can ensure that the first locking member 41 can match and fix with the second locking member 42 on the sliding trajectory of the second locking member 42.

[0049] In one embodiment, the first locking member 41 is a locking groove, and the second locking member 42 is a locking head; after the locking head slides into the locking groove, the swing arm assembly 20 is locked. It can be understood that the first locking member 41 and the second locking member 42 control the locking of the first locking member 41 in the longitudinal direction by matching the locking head and the locking groove in the lateral direction, so as to control the positioning of the secondary auxiliary swing arm 23.

[0050] When the secondary swing arm 22 and the secondary auxiliary swing arm 23 are retracted to the edge of the window sash 300, the groove of the locking lock slot and the locking lock head are on the same straight line and above the locking component slide rail 111. Rotate the operating handle to move the locking lock head into the locking lock slot to achieve matching. The locking lock slot is locked in a direction perpendicular to the locking component slide rail 111.

[0051] In another embodiment, the first locking element 41 is a locking lock head, and the second locking element 42 is a locking lock groove; its principle is the same as the above scheme.

[0052] Furthermore, the locking groove includes an inlet portion 412, a locking portion 413, and an outlet portion 414. The inlet portion 412 and the outlet portion 414 are symmetrically arranged at both ends of the locking portion 413. Both the inlet portion 412 and the outlet portion 414 are wedge-shaped grooves, and the width of the opening of the wedge-shaped groove is greater than the width of the locking portion 413. It can be understood that when the first locking member 41 and the second locking member 42 are in a matching state, the locking groove has the inlet portion 412, the locking portion 413, and the outlet portion 414 sequentially opened along the direction of movement of the locking head. The inlet portion 412 and the outlet portion 414 are both provided with wedge-shaped grooves to facilitate the insertion of the locking head, and the width of the locking portion 413 is slightly narrower than the outer diameter of the locking head to ensure that the locking head can be stably fixed in the locking groove.

[0053] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
