DETAILED DESCRIPTION

[0044] In order to enable those skilled in the art to more clearly understand the objectives, technical solutions and advantages of the present invention, the present invention is further described below with reference to the accompanying drawings and embodiments.

[0045] Reference Figures 1 to 3 , Figures 1 to 3 The first embodiment of the hinge assembly 10 of the present invention is shown. In the embodiment shown in the accompanying drawings, the hinge assembly 10 includes a first hinge assembly 13 and a second hinge assembly 14, wherein the first hinge assembly 13 includes a first slide rail 111 fixed to the frame 30, a first support plate 121 fixed to the fan body 20, and a first connecting rod assembly 131 disposed between the first slide rail 111 and the first support plate 121, and the first connecting rod assembly 131 can slide along the first slide rail 111; the second hinge assembly 14 is located below the first hinge assembly 13, and includes a second slide rail 112 fixed to the frame 30, a second support plate 122 fixed to the fan body 20, and a second connecting rod assembly disposed between the second slide rail 112 and the second support plate 122. The second connecting rod assembly includes a fourth connecting rod 1412, the two ends of which are rotatably connected to the second support plate 122 and the second slide rail 112, respectively. Based on the above design, the present invention can realize the large-angle opening of the fan body 20 in the top-hung window through the first hinge assembly 13 and the second hinge assembly 14, so as to solve the problem that the traditional hanging window hinge cannot realize a large opening angle. That is, when opening, the first connecting rod assembly 131 is driven to slide down at the same time by the gravity of the fan body 20. At this time, the center of gravity G of the fan body 20 is as follows: Figure 4 As shown, rapid descent achieves the purpose of rapid opening; at the same time, during the descent, the second hinge assembly 14 for supporting the fan body 20, which is arranged below the first hinge assembly 13, can assist in achieving rapid opening of the fan body 20 and can fix and support the fan body 20, which is convenient for escape in the event of an accident.

[0046] Specifically, if Figure 2 and Figure 3 As shown, in this embodiment, the first connecting rod assembly 131 includes a first connecting rod 1311, a second connecting rod 1312, and a slider 1313. The slider 1313 is slidably connected to the first slide rail 111. The ends of the first connecting rod 1311 and the second connecting rod 1312 are respectively rotatably connected to the slider 1313 and the first supporting plate 121. Preferably, in this embodiment, the slider 1313 is an integrated structure. Based on this design, the cooperation between the first connecting rod 1311 and the second connecting rod 1312, the slider 1313, and the first supporting plate 121 facilitates the wide-angle opening of the sash 20 in the top-hung window.

[0047] Furthermore, the hinge assembly 10 also includes a fan fixing column 15, which is installed on the fan body 20, and one end of which is connected to the first connecting rod 1311 and the first supporting plate 121 through a rotating shaft 16. Specifically, in this embodiment, the rotating shaft 16 passes through the first connecting rod 1311 and the first supporting plate 121 in sequence and is connected to the fan fixing column 15.

[0048] Preferably, in this embodiment, the first slide rail 111 and the second slide rail 112 are integrally formed, forming a one-piece structure, while the first supporting piece 121 and the second supporting piece 122 are separate structures, respectively fixed to the upper end and the middle portion of the fan body 20. It is understood that in certain other embodiments, the first slide rail 111 and the second slide rail 112 may be separate structures, while the first supporting piece 121 and the second supporting piece 122 may be integrally formed, forming a one-piece structure.

[0049] Reference Figures 5 and 6 , Figures 5 and 6The second embodiment of the present invention is shown. The difference between this embodiment and the first embodiment is that the structures and connection relationships of the components of the second hinge assembly 14 in this embodiment are slightly different, and the rest of the structures are the same or similar. Specifically, in this embodiment, the second connecting rod assembly also includes a third connecting rod 1411, the two ends of the third connecting rod 1411 are respectively rotatably connected to the fourth connecting rod 1412 and the second slide rail 112, and the second slide rail 112 is provided with a movable slider 1414 slidably connected to the second slide rail 112 and a fixed block 1413 fixed to the second slide rail 112, and the movable slider 1414 is located above the fixed block 1413, and the third connecting rod 1411 and the fourth connecting rod 1412 are respectively rotatably connected to the movable slider 1414 and the fixed block 1413 to realize their rotational connection with the second slide rail 112 (in this embodiment, the fourth connecting rod 1412 is rotatably connected to the fixed block 1413 fixed on the second slide rail 112, thereby indirectly rotatably connected to the second slide rail 112. In other embodiments, it can also be directly rotatably connected to the second slide rail 112). As can be seen, when the user opens or closes the window body 20, the movable slider 1414 in the second hinge assembly 14 can move along the second slide rail 112 under the action of a push or pull force. Since the center of gravity of the window body 20 gradually moves downward during movement, the gravity of the window body 20 actually performs work, thereby allowing the window body 20 to be opened further quickly. After opening, the window cleaning distance is greatly improved compared to traditional sliding-supported hung windows, making it easier for owners to maintain the cleanliness of the window glass. Preferably, the third connecting rod 1411 and the movable slider 1414 and the fourth connecting rod 1412, as well as the fourth connecting rod 1412 and the fixed block 1413 and the second supporting plate 122, are all rotatably connected by rivet shafts.

[0050] Reference Figures 7 to 9 , Figures 7 to 9 The third embodiment of the present invention is shown. The difference between this embodiment and the first embodiment lies in that the structures and connection relationships of the various components of the first hinge assembly 13 in this embodiment are slightly different, while the remaining structures are the same or similar. Specifically, the second connecting rod 1312 is riveted to the slider 1313 via a first adapter 1318, and the middle portions of the first connecting rod 1311 and the second connecting rod 1312 in the first connecting rod assembly 131 are also riveted together via a rivet shaft. A slide groove 1211 is also provided on the first supporting plate 121. In this embodiment, the first connecting rod 1311 is connected to the first supporting plate 121 via a first rotating shaft 17, and the first rotating shaft 17 is located in the slide groove 1211 and can move within the slide groove 1211. Based on the above design, the hinge assembly 10 of this embodiment can also quickly achieve a large-angle opening of the fan body 20.

The second slide rail 112 is provided with a movable slider 1414 slidably connected to the second slide rail 112 and a fixed block 1413 fixed to the second slide rail 112. The movable slider 1414 is located above the fixed block 1413. The third link 1411 and the fourth link 1412 are rotatably connected to the movable slider 1414 and the fixed block 1413, respectively, to indirectly achieve rotational connection with the second slide rail 112. It can be seen that when a user opens or closes the fan body 20, the movable slider 1414 in the second hinge assembly 14 can move along the second slide rail 112 under the action of a push or pull force.

The third and fourth sliders 1316 and 1317 are slidably connected to the first slide rail 111. The second link 1312 is pivotally connected to the fourth slider 1317 and the connecting plate 1315 at both ends. One end of the first link 1311 is pivotally connected to the third slider 1316, and the other end is pivotally connected to the connecting plate 1315 via the fifth link 1314. The connecting plate 1315 is connected to the first support 121. The first link 1311 and the second link 1312 are pivotally connected at their midpoints. Based on the above design, the hinge assembly 10 of this embodiment can also quickly achieve a wide-angle opening of the fan body 20.

[0059] Reference Figure 25 , Figure 25 This is a structural diagram of the twelfth embodiment of the hinge assembly 10 of the present invention. The difference between this embodiment and the eleventh embodiment is that the structures and connection relationships of the various components of the second hinge assembly 14 in this embodiment are slightly different, and the remaining structures are the same or similar. Specifically, in this embodiment, the second connecting rod assembly also includes a third connecting rod 1411, and the two ends of the third connecting rod 1411 are respectively rotatably connected to the fourth connecting rod 1412 and the second slide rail 112. The second slide rail 112 is provided with a movable slider 1414 slidably connected to the second slide rail 112 and a fixed block 1413 fixed to the second slide rail 112, and the movable slider 1414 is located above the fixed block 1413.

[0060] Furthermore, in certain other embodiments, the fourth link 1412 can also be connected to the second slide rail 112 through an adjustment component, and the adjustment component can adjust the relative position of the fourth link 1412 on the second slide rail 112. Specifically, the adjustment component may include an eccentric adjustment member and an adjustment plate, and the adjustment plate is located on the back of the second slide rail 112. The eccentric adjustment member passes through the fixed block 1413, the second slide rail 112 and the adjustment plate in sequence. The first end of the fourth link 1412 is rotatably connected to the adjustment plate through a rotating shaft passing through the second slide rail 112. When the eccentric adjustment member rotates, the adjustment plate follows the movement, thereby pulling the fourth link 1412 to move, so that the entire hinge assembly can be adjusted in position to adapt to different window types.

[0061] In summary, the present invention can achieve a large-angle opening of the fan body in the top-hung window through the first connecting rod assembly and the second connecting rod assembly. That is, when opening, the first connecting rod assembly is driven to open and slide down at the same time by the weight of the fan body. At this time, the center of gravity of the fan body drops rapidly to achieve the purpose of rapid opening; at the same time, during the descent, the second hinge assembly for supporting the fan body is arranged below the first hinge assembly to assist in achieving rapid opening of the fan body and can fix and support the fan body.
