When the extension structure 100 needs to be retracted, the third frame 130 moves in a direction close to the first frame 110. The third frame 130 drives the second frame 120 to move, so that the third frame 130 and the second frame 120 can be at least partially accommodated in the installation groove 111 of the first frame 110, thereby reducing the space occupied and improving space utilization.

[0039] In this embodiment, the extension structure 100 has at least a first assembly position and a second assembly position. Figure 1 As shown, when the extension structure 100 is in the first assembly position, the third frame 130 and the second frame 120 can be accommodated in the installation groove 111 of the first frame 110, ensuring that the extension structure 100 has a smaller space occupancy rate and reducing the obstruction and impact on personnel use; Figure 2 As shown, when the extension structure 100 is in the second assembly position, the transmission assembly 140 drives the third frame 130 and the second frame 120 to move relative to the first frame 110, so as to achieve the effect of spatial expansion and extension of the extension structure 100, so that the extension structure 100 can balance the space utilization contraction and space extension and expansion as needed.

In other words, the first slide rail 131 of the third frame 130 is set along the height direction of the extension structure 100, so that the first transmission member 142 and the second transmission member 143 can move relative to each other on the first slide rail 131 along the height direction of the extension structure 100, so that the first transmission member 142 and the second transmission member 143 can jointly push the third frame 130 to move in the direction away from the first frame 110, so as to realize the expansion and use requirements of the extension structure 100.

[0043] In one embodiment, optionally, reference Figure 2 and Figure 4As shown, the third frame 130 can move along the second direction Z, the second direction Z is perpendicular to the first direction X, the sliding direction of the first transmission member 142 on the first slide rail 131 is perpendicular to the second direction Z, the sliding direction of the second transmission member 143 on the first slide rail 131 is perpendicular to the second direction Z, the third frame 130 can move along the length direction of the extension structure 100, the first transmission member 142 moves along the height direction of the extension structure 100 on the first slide rail 131, the second transmission member 143 moves along the height direction of the extension structure 100 on the first slide rail 131, the moving directions of the first transmission member 142 and the second transmission member 143 are perpendicular to the moving direction of the third frame 130, so that the movement of the first transmission member 142 and the second transmission member 143 is converted into the perpendicular movement of the third frame 130.

[0044] In summary, the utility model provides an extension structure 100 and a window, wherein the transmission assembly 140 is installed in the installation groove 111, the transmission assembly 140 is respectively connected to the first frame 110 and the third frame 130, the outside of the first frame 110 is used to install the window glass, the transmission assembly 140 can drive the third frame 130 and the second frame 120 to move relative to the first frame 110, and the third frame 130 can move relative to the first frame 110 under the drive of the transmission assembly 140. At this time, the second frame 120 moves under the drive of the third frame 130, and the second frame 120 and the third frame 130 move along the preset path toward By moving in a direction away from the first frame body 110, the positions of the second frame body 120 and the third frame body 130 are changed, so that the extension structure 100 is extended and expanded by the position movement of the second frame body 120 and the third frame body 130, thereby improving the extension effect. When the extension structure 100 needs to be retracted, the third frame body 130 moves in a direction close to the first frame body 110, and the third frame body 130 drives the second frame body 120 to move, so that the third frame body 130 and the second frame body 120 can be at least partially accommodated in the installation groove 111 of the first frame body 110, reducing the space occupied, improving space utilization, and thus improving the user experience.

[0045] Example 2

[0046] refer to Figures 1 to 3 As shown, an embodiment of the present application provides another extension structure 100 , which includes a first frame 110 , a second frame 120 , a third frame 130 and a transmission assembly 140 .

[0047] Specifically, combined Figure 2 and Figure 3As shown, the first frame body 110 is provided with a mounting groove 111; one side of the second frame body 120 is movably connected to the first frame body 110; the third frame body 130 is movably connected to a side of the second frame body 120 facing away from the first frame body 110, and the third frame body 130 and the second frame body 120 can move relative to the first frame body 110.

[0048] In this embodiment, the transmission assembly 140 is arranged in the installation groove 111, one end of the transmission assembly 140 is connected to the first frame 110, and the end of the transmission assembly 140 away from the first frame 110 is movably connected to the third frame 130, so that the third frame 130 and the second frame 120 can both move in a direction away from the first frame 110, or the third frame 130 and the second frame 120 can both be at least partially accommodated in the installation groove 111. Accordingly, the transmission assembly 140 is installed in the installation groove 111, and the transmission assembly 140 is respectively connected to the first frame 110 and the third frame 130. The outside of the first frame 110 is used to install window glass. The transmission assembly 140 can drive the third frame 130 and the second frame 120 to move relative to the first frame 110, and the third frame 130 and the second frame 120 can move relative to the first frame 110. The body 130 can move relative to the first frame 110 under the drive of the transmission assembly 140. At this time, the second frame 120 moves under the drive of the third frame 130. The second frame 120 and the third frame 130 move along the preset path in the direction away from the first frame 110, so that the positions of the second frame 120 and the third frame 130 are changed, so that the extension structure 100 is extended and expanded by the position movement of the second frame 120 and the third frame 130, thereby improving the extension effect. When the extension structure 100 needs to be retracted, the third frame 130 moves in the direction close to the first frame 110, and the third frame 130 drives the second frame 120 to move, so that the third frame 130 and the second frame 120 can be at least partially accommodated in the installation groove 111 of the first frame 110, reducing the occupied space and improving space utilization.

[0049] In this embodiment, the extension structure 100 has at least a first assembly position and a second assembly position. Figure 1 As shown, when the extension structure 100 is in the first assembly position, the third frame 130 and the second frame 120 can be received in the installation groove 111 of the first frame 110. Figure 2 As shown, when the extension structure 100 is in the second assembly position, the transmission assembly 140 drives the third frame 130 and the second frame 120 to move relative to the first frame 110, thereby achieving the effect of spatial expansion and extension of the extension structure 100.

[0050] Combine Figures 1 to 3As shown, the extension structure 100 has a first direction X, a second direction Z, and a third direction Y, wherein the first direction X, the second direction Z, and the third direction Y are perpendicular to each other. For example, the first direction X is the height direction of the extension structure 100, the second direction Z is the length direction of the extension structure 100, and the third direction Y is the width direction of the extension structure 100.

[0051] In one embodiment, optionally, reference Figure 3 As shown, the transmission assembly 140 includes a support member 141, a first transmission member 142, and a second transmission member 143. The support member 141 is connected to the first frame 110, one end of the first transmission member 142 is hinged to the support member 141, one end of the second transmission member 143 is hinged to the support member 141, the first transmission member 142 and the second transmission member 143 are hinged, the support member 141 is installed on the first frame 110, the first transmission member 142 and the second transmission member 143 are connected to the first frame 110 through the support member 141, and are used to support the first transmission member 142 and the second transmission member 143. During the transmission process between the first transmission member 142 and the second transmission member 143, the position and posture of the first transmission member 142 and the second transmission member 143 can be changed. For example, the first transmission member 142 is a first transmission rod, and the second transmission member 143 is a second transmission rod.

[0052] Alternatively, as Figure 3 and Figure 4 As shown, the transmission assembly 140 further includes an elastic member 144. The connection position of the first transmission member 142 and the second transmission member 143 forms an intersection 145. One end of the elastic member 144 is connected to the intersection 145, and the end of the elastic member 144 away from the intersection 145 is connected to the support member 141. That is, the elastic member 144 is connected to the intersection 145 of the first transmission member 142 and the second transmission member 143. The elastic member 144 limits the first transmission member 142 and the second transmission member 143 to a certain extent and controls the preset transmission trajectory of the transmission assembly 140 to prevent the preset transmission trajectory of the transmission assembly 140 from being offset or misaligned. Exemplarily, the elastic member 144 is a constant pressure spring or a return spring.

[0053] Optionally, refer to Figure 4 and Figure 5As shown, the third frame 130 is provided with a first slide rail 131 along the first direction X, the first transmission member 142 is slidably connected to the first slide rail 131 at one end away from the support member 141, and the second transmission member 143 is slidably connected to the first slide rail 131 at one end away from the support member 141. In other words, the first slide rail 131 of the third frame 130 is set along the height direction of the extension structure 100, so that the first transmission member 142 and the second transmission member 143 can move relative to each other on the first slide rail 131 along the height direction of the extension structure 100, so that the first transmission member 142 and the second transmission member 143 can jointly push the third frame 130 to move in the direction away from the first frame 110, so as to realize the expansion and use requirements of the extension structure 100.

[0054] Optionally, the first transmission member 142 and the second transmission member 143 are arranged in a staggered manner, that is, the staggered arrangement of the first transmission member 142 and the second transmission member 143 allows the first transmission member 142 and the second transmission member 143 to form a telescopic support structure, so as to facilitate the control and adjustment of the transmission extension length of the transmission assembly 140, driving the third frame 130 and the second frame 120 to expand and extend, thereby achieving better technical effects. Furthermore, the first transmission member 142 and the second transmission member 143 are arranged at an angle.

[0055] In one embodiment, the extension structure 100 optionally further includes a drive assembly, which drives the first transmission member 142 to move relative to each other via a sliding member 146, and / or drives the second transmission member 143 to move relative to each other via the sliding member 146. Accordingly, the drive assembly may include one or more drive motors, one drive motor corresponding to the first transmission member 142, which drives the first transmission member 142 to move relative to each other via the sliding member 146, so that when the drive motor drives the sliding member 146 to move, the sliding member 146 drives the first transmission member 142 to move relative to each other along the height direction of the extension structure 100. Alternatively, one drive motor corresponds to the second transmission member 143, so that when the drive motor drives the sliding member 146 to move, the sliding member 146 drives the second transmission member 143 to move relative to each other along the height direction of the extension structure 100, so that the relative movement of the first transmission member 142 and the second transmission member 143 drives the movement of the third frame 130 and the second frame 120, making the entire transmission trajectory simple and effective, and achieving a better extension effect. Exemplarily, the driving motor may be a stepper motor, which converts an electrical pulse signal into a corresponding angular displacement or linear displacement to achieve precise position control of the sliding member 146 .

[0056] Further, refer to Figure 5 and Figure 7As shown, the sliding member 146 includes a connecting portion 1461 and a clamping portion 1462. One side of the connecting portion 1461 is connected to the clamping portion 1462, and the side of the connecting portion 1461 facing away from the clamping portion 1462 is connected to the first transmission member 142 or the second transmission member 143. The clamping portion 1462 can be movably engaged with the first slide rail 131. Exemplarily, the clamping portion 1462 is an I-shaped structure.

[0057] In one embodiment, optionally, reference Figure 2 and Figure 4 As shown, the third frame 130 can move along the second direction Z, which is perpendicular to the first direction X. The sliding direction of the first transmission member 142 on the first slide rail 131 is perpendicular to the second direction Z, and the sliding direction of the second transmission member 143 on the first slide rail 131 is perpendicular to the second direction Z. The third frame 130 can move along the length direction of the extension structure 100. The first transmission member 142 moves along the height direction of the extension structure 100 on the first slide rail 131, and the second transmission member 143 moves along the height direction of the extension structure 100 on the first slide rail 131. The movement directions of the first transmission member 142 and the second transmission member 143 are both perpendicular to the movement direction of the third frame 130, so that the movement of the first transmission member 142 and the second transmission member 143 is converted into the perpendicular movement of the third frame 130. Furthermore, the movement direction of the second frame 120 is perpendicular to the sliding directions of the first transmission member 142 and the second transmission member 143, respectively.

[0058] In one embodiment, optionally, in combination Figure 2 and Figure 6 As shown, a second slide rail structure 150 and a third slide rail structure 160 are provided on opposite sides of the second frame 120 along the second direction Z, the first frame 110 is slidably connected to the second frame 120 through the second slide rail structure 150, and the third frame 130 is slidably connected to the second frame 120 through the third slide rail structure 160. During the transmission process of the transmission assembly 140, the third frame 130 is moved relative to the second frame 120 through the third slide rail structure 160, and the second frame 120 is moved relative to the first frame 110 through the second slide rail structure 150, so as to expand and extend the space of the extension structure 100 through the second frame 120 and the third frame 130, thereby having a better extension effect.
