[0041] Reference Figures 1 to 3 , the following will give several embodiments of a sunshade sliding structure and a door and window of the utility model.

[0042] As Figures 1 to 3As shown, the sun-shading sliding structure is applied to a door / window 800, the door / window 800 comprises a frame 810 and a movable sash 820 connected by sliding, the frame 810 is provided with a slide rail along a horizontal long end, the horizontal long end of the frame 810 is arranged along a left-right direction, when the movable sash 820 is installed on the frame 810, the movable sash 820 slides in the slide rail left and right, and a first installation cavity is formed in the movable sash 820.

[0043] In the embodiment, the sun-shading sliding structure comprises a driving mechanism 100, a conductive rail 200, a first electric shutter 300, a light sensing mechanism 400 and an electric control mechanism 500, as shown. Figure 2

[0044] It can be understood that the driving mechanism 100 is arranged in the frame 810, the driving mechanism 100 and the frame 810 are relatively fixed, the output end of the driving mechanism 100 is connected with the movable sash 820, when the driving mechanism 100 is started, the output end of the driving mechanism 100 drives the movable sash 820 to slide along the horizontal long end of the frame 810, and the movable sash 820 is controlled to move left and right along the slide rail.

[0045] In the embodiment, the driving mechanism 100 is a linear motion mechanism such as a linear motor and a screw rod motor.

[0046] It can be understood that the conductive rail 200 is arranged in the frame 810, the conductive rail 200 is arranged along the horizontal long end of the frame 810, that is, the conductive rail 200 extends along the left-right direction, as shown. Figure 2 Specifically, the top of the frame 810 is formed with a left-right extending placement cavity, the conductive rail 200 is embedded in the placement cavity, so that the conductive rail 200 is hidden in the frame 810, and the conductive rail 200 is prevented from being exposed. The slide rail is located below the placement cavity, and the slide rail and the movable sash 820 are connected by sliding, so that the rainwater outside does not cause the conductive rail 200 to be short-circuited.

[0047] It can be understood that the first electric shutter 300 is arranged in the first installation cavity, when the first electric shutter 300 is opened, the first electric shutter 300 lowers the blades, so that the blades can cover the light-transmitting part of the movable sash 820, thereby realizing the sun-shading effect. The first electric shutter 300 is in sliding contact with the conductive rail 200, as shown, the first electric shutter 300 is powered through the conductive rail 200, so that the first electric shutter 300 can be controlled to be opened and closed. Figure 2

[0048] In this way, since the conductive rail 200 extends along the left-right direction, when the movable sash 820 slides at any position of the slide rail, the first electric shutter 300 is always in sliding contact with the conductive rail 200, so that the opening and closing state of the movable sash 820 does not interfere with the power-on state of the first electric shutter 300, and the conductive rail 200 is hidden and arranged, so that the exposure does not affect the appearance or cause short circuit and the like.​​

[0049] It can be understood that the light sensing mechanism 400 is connected to the side of the frame 810 facing the outside to detect the outdoor light intensity. The first electric louver 300 can control the lifting of the blades and adjust the angle of the blades through electric control. It can be understood that the electric control mechanism 500 and the light sensing mechanism 400 are electrically connected to receive the outdoor light intensity detected by the light sensing mechanism 400. The electric control mechanism 500 is also electrically connected to the driving mechanism 100 and the first electric louver 300 respectively to control the driving mechanism 100 and the first electric louver 300 to open and close respectively after receiving the signal of the outdoor light intensity.

[0050] In this way, the sunshade sliding structure monitors the outdoor light intensity through the light sensing mechanism 400, and when the set light intensity is reached, the electric control mechanism 500 automatically controls the opening and closing of the first electric louver 300 and the movable fan 820.

[0051] It can be understood that the user can set the opening and closing conditions of the movable fan 820 and the first electric louver 300 in advance according to time, light intensity, work and rest, etc.

[0052] For example, when it is the user's sleep time, the electric control mechanism 500 can automatically control the driving mechanism 100 to close the movable fan 820 and open the first electric louver 300, and adjust the angle of the blades to prevent outdoor light from shining into the room, so that the user has a completely dark sleep environment and promotes falling asleep.

[0053] For example, when it is the user's wake-up time, the electric control mechanism 500 can automatically control the driving mechanism 100 to open the movable fan 820 and close the first electric louver 300, so as to facilitate the exchange of indoor and outdoor air, and the natural light outside can illuminate the indoor environment.

[0054] For example, when it is daytime but the light intensity detected by the light sensing mechanism 400 is small, the electric control mechanism 500 can automatically control the driving mechanism 100 to close the movable fan 820 to avoid the situation that rainwater drifts into the room in rainy days in advance.

[0055] For example, when it is the noon period and the light intensity detected by the light sensing mechanism 400 is large, the electric control mechanism 500 can automatically control the first electric louver 300 to open and adjust the blades for sunshade to avoid the strong outdoor light from damaging indoor furniture, etc.

[0056] For example, when it is the night period and the light intensity detected by the light sensing mechanism 400 is small, the electric control mechanism 500 can automatically control the first electric louver 300 to close to facilitate the user to enjoy the outdoor night scene through the window.

[0057] It can be understood that the sunshade sliding structure also includes a power supply mechanism 600 for realizing the sliding touch connection of the first electric louver 300 and the conductive rail 200, such asFigure 2 Specifically, the power supply mechanism 600 is connected to the movable fan 820 and fixed relative to the movable fan 820, and the power supply mechanism 600 slides left and right when the movable fan 820 slides relative to the slide rail. The power supply mechanism 600 includes two conductive ends, one of which is connected to the power line of the first electric shutter 300 through the first installation cavity, and the other conductive end extends upward and penetrates into the placement cavity, so that it is in sliding contact with the conductive rail 200, thereby realizing the sliding contact between the first electric shutter 300 and the conductive rail 200.

[0058] It can be understood that the end of the power supply mechanism 600 extending upward is provided with a carbon brush, and the surface material of the conductive rail 200 is a copper sheet. The power supply mechanism 600 is always in contact with the copper sheet through the carbon brush to realize power supply.

[0059] In this embodiment, the light sensing mechanism 400 includes a support 410 and a light sensor 420, as shown in Figure 3 .

[0060] It can be understood that the support 410 is connected to the front top of the frame 810, as shown in Figure 2 . A rotating motor is arranged in the support 410. Since the light sensing mechanism 400 is located on the side of the frame 810 facing the outdoor, the rotating motor is protected in the support 410 to avoid wind, rain and sun.

[0061] It can be understood that the light sensor 420 has a light intensity sensing module 421, as shown in Figure 3 . The light intensity sensing module 421 is used to detect the light intensity of the outdoor. The light sensor 420 is rotatably connected to the support 410 at both ends in the left-right direction, so that it can rotate relative to the support 410 about the left-right axis to adjust the angle of the light intensity sensing module 421. The output end of the rotating motor is in transmission connection with the light sensor 420, so as to automatically adjust the angle of the light intensity sensing module 421.

[0062] Further, the angle of the light intensity sensing module 421 can be set according to the installation height, installation direction and installation position of the sunshade sliding structure, so that the light intensity sensing module 421 can accurately obtain the solar light intensity of the outdoor.

[0063] It can be understood that the installation height is the height of the sunshade sliding structure from the ground level or the floor height of the building, etc. The installation direction is the direction of the side of the frame 810 facing the outdoor, i.e. the east, south, west and north directions. The installation position is the longitude and latitude of the sunshade sliding structure, so that the angle of the light intensity sensing module 421 is associated with the emission angle of the sunlight.

[0064] It can be understood that the support 410 is provided with a control mechanism, which obtains the installation height, installation direction and installation position set by the user through wireless or wired connection, automatically calculates the rotation direction and rotation angle of the light sensor 420, and controls the rotation motor to start, so that the light intensity sensing module 421 is driven to rotate to the calculated angle.

[0065] It can be understood that the support 410 is provided with a battery, which is electrically connected with the rotation motor, and the battery provides power for the rotation motor and the light sensor 420. The outer end surface of the light sensor 420 is provided with a solar panel 422, which is electrically connected with the battery. The solar panel 422 converts solar energy into electrical energy and stores it in the battery, so that the light sensing mechanism 400 does not need external power supply, and the structure is simpler.

[0066] Further, the control mechanism is provided with a minimum power. When the control mechanism detects that the battery is lower than the minimum power, the control mechanism controls the rotation motor to start, so that the solar panel 422 rotates to the angle with the maximum light intensity. Specifically, the output end of the rotation motor drives the light sensor 420 to rotate within the rotatable angle range. The light intensity sensing module 421 detects the light intensity corresponding to different angles and sends the light intensity corresponding to the angle to the control mechanism. After obtaining the light intensity, the control mechanism controls the rotation motor to rotate, so that the solar panel 422 rotates to the angle with the maximum light intensity.

[0067] In this way, the solar panel 422 can quickly capture the strongest light and quickly charge the battery, ensuring that the battery has sufficient power to supply the rotation motor and the light sensor 420.

[0068] In this embodiment, the minimum power is 10% of the maximum power of the battery.

[0069] It can be understood that the light intensity sensing module 421 and the solar panel 422 are located at the same end surface of the light sensor 420, as shown in Figure 3 so that the electric control mechanism 500 and the control mechanism do not interfere with each other. The light intensity sensing module 421 can be used to sense the outdoor light intensity, which is convenient for the electric control mechanism 500 to control the opening and closing of the movable fan 820 and the first electric shutter 300, and can also be used to quickly charge the battery.

[0070] It can be understood that the support 410 is provided with a charging port 411 electrically connected with the battery, as shown in Figure 3As shown in FIG. 7, when the control mechanism detects that the battery power is lower than the minimum power, and the light intensity sensing module 421 cannot detect a large light intensity within the rotation angle, i.e. the outdoor environment is weakly illuminated, such as in overcast or night conditions, the solar panel 422 cannot convert electrical energy through solar energy, and the user can charge the battery through the charging port 411 to ensure that the light sensor 420 is always in working condition.

[0071] In this embodiment, the charging port 411 is located at the right end surface of the support 410, as shown in FIG. 8. Figure 3

[0072] In some embodiments, the door and window 800 includes a plurality of movable sashes 820. Correspondingly, the plurality of movable sashes 820 respectively correspond to the power supply mechanism 600, the first electric louver 300 and the driving mechanism 100, so that each movable sash 820 is connected to the conductive rail 200 through the corresponding power supply mechanism 600, and the electric control mechanism 500 controls all the driving mechanisms 100 and all the first electric louvers 300, thereby controlling the position and shading effect of one or more movable sashes 820.

[0073] In this embodiment, the door and window 800 includes a fixed sash 830, as shown in FIG. 9 and FIG. 10. Figure 1 Figure 2 As shown in FIG. 9 and FIG. 10, the fixed sash 830 is fixedly connected with the frame 810, and the movable sash 820 slides in the sliding rail, so that the movable sash 820 can slide to overlap the front and back of the fixed sash 830, facilitating the user to enter or exit or exchange air between indoor and outdoor.

[0074] It can be understood that the fixed sash 830 is hollow to form a second mounting cavity. Correspondingly, the shading sliding structure further includes a second electric louver 700 mounted in the second mounting cavity, as shown in FIG. 11 and FIG. 12. Figure 1 Figure 2 As shown in FIG. 11 and FIG. 12, the second electric louver 700 is electrically connected with the electric control mechanism 500, so that the electric control mechanism 500 can control the opening and closing and blade angle adjustment of the second electric louver 700.

[0075] It can be understood that, since the fixed sash 830 and the frame 810 are relatively fixed, the second electric louver 700 can be directly connected with the electric control mechanism 500 for power supply, without the need to set the conductive rail 200, the power supply mechanism 600 and the like, so that the structure is simpler.

[0076] It can be understood that, when the user needs shading, the electric control mechanism 500 controls the driving mechanism 100, the first electric louver 300 and the second electric louver 700 to start, so that the movable sash 820 is closed, the outdoor light is prevented from entering through the gap between the movable sash 820 and the frame 810, and the first electric louver 300 and the second electric louver 700 are lowered and the blades are adjusted to a shading angle, thereby preventing the outdoor light from entering the indoor.

[0077] ​​​Further, the first electric louver 300 and the second electric louver 700 are linked together, so that the control of the electric control mechanism 500 is more convenient, and the first electric louver 300 and the second electric louver 700 are simultaneously lifted and adjusted in angle, so that the two have the same shading effect.

[0078] It can be understood that the frame 810 includes an upper frame 811, a lower frame 812 and two side frames. Figure 2 Figure 2 As shown, the guide rails are arranged on the upper frame 811 and the lower frame 812 respectively, so as to support and guide the upper end and the lower end of the movable sash 820 to move left and right.

[0079] It can be understood that the electric control mechanism 500 and the control mechanism can be a single-chip microcomputer or a PCL controller, which can simply realize the control of the driving mechanism 100 and the rotating motor and the like. It should be noted that the control mode of the controller does not belong to the protection scope of the utility model, and belongs to the prior art. The utility model mainly protects the connection mode of the controller.

[0080] It can be understood that the fixed sash 830 is directly connected with the electric control mechanism 500, and the structure is simple. Therefore, the electric control mechanism 500 is hiddenly arranged in the corresponding frame 810 above the fixed sash 830. The electric control mechanism 500 can be connected with an external power supply through the electric wire embedded in a wall and passing through the frame 810, so as to supply power to the driving motor, the first electric louver 300 and the like.

[0081] The door and window 800 of the utility model embodiment includes a frame 810, a movable sash 820 and a sunshade sliding structure.

[0082] It can be understood that the door and window 800 is a sliding door or a sliding window. The sunshade sliding structure can be applied to the sliding door or the sliding window, so that the sliding door or the sliding window automatically opens and closes the movable sash 820 according to the light intensity and automatically opens the sunshade function.

[0083] In some embodiments, the sliding door or the sliding window includes two or more movable sashes 820, and a user can open any movable sash 820 to enter or exchange air.

[0084] In some other embodiments, the sliding door or the sliding window includes a movable sash 820 and a fixed sash 830, and a user can install the movable sash 820 according to an entering position or a ventilation position, and when the movable sash 820 is opened, the movable sash 820 slides to the rear of the fixed sash 830. In the embodiment, the sliding door or the sliding window includes one movable sash 820 and one fixed sash 830.

[0085] The preferred embodiments of the present application are specifically described above, but the present application is not limited to the embodiments, and those skilled in the art can make various equivalent modifications or replacements without departing from the spirit of the present application.
