[0020] (III) Beneficial Effects

[0021] This utility model provides an automatic folding and lifting window. It has the following beneficial effects:

[0022] 1. This utility model uses a lifting motor to move the first window section connected to the transmission chain downwards under its own weight. Under the limiting action of the vertical track, the connecting hook, and the connecting groove, the first and second window sections descend synchronously. The stepping slide rod at the upper end of the stepping lever slides from the docking guide groove into the translational inclined groove in the translational guide rail under the pressure of the first and second window sections' gravity. This causes the stepping lever to rotate around the pivot axis. The horizontal push slide rod at the lower end of the stepping lever pushes the side wall of the horizontal push guide rail in the horizontal direction, causing the third window section to slide horizontally and connect with the guide rail. The second window section is misaligned, allowing it to descend and guide the third window to its initial position, where it rests against the sliding support. The sliding groove then engages with the upper end of the third window section. At this point, the stepping slide rod slides into the vertical groove of the first window section's stepping guide rail, causing the first window section to descend continuously. Through the stepping inclined groove and stepping vertical groove, the stepping lever rotates further, and the sliding slide rod pushes the third window section, along with the second window section, further away. This allows the first window section to continue moving downwards and transitioning to the initial position of the third window section, completing the lifting and folding of the folding window assembly and ensuring effective indoor ventilation.

[0030] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0031] This utility model embodiment provides, as follows: Figure 1-3 As shown, an automatic folding and lifting window includes a support frame 1. The support frame 1 is provided with a vertical track 2 and a horizontal track 3 that are interconnected. Two parallel horizontal tracks 3 are provided on the lower side of the support frame 1. A folding window assembly is slidably installed on the support frame 1. The folding window assembly includes a first window section 4, a second window section 5, and a third window section 6 from top to bottom. The first window section 4, the second window section 5, and the third window section 6 are provided with translation rollers. The translation rollers 22 on the first window section 4, the second window section 5, and the third window section 6 can slide from the vertical track 2 into the horizontal track 3.

[0032] like Figure 4 As shown, the support frame 1 has an installation space inside, the stepping lever 8 is set in the installation space, the installation space has a pivot shaft 7, the stepping lever 8 is rotatably connected to the pivot shaft 7, the stepping lever 8 extends from the pivot shaft 7 to the upper and lower sides, the side wall of the support frame 1 has two arc-shaped through grooves 9, the upper and lower ends of the stepping lever 8 are respectively provided with stepping slide rods 10 and flat push slide rods 11, the stepping slide rods 10 and flat push slide rods 11 pass through the upper and lower arc-shaped through grooves 9 respectively.

[0033] like Figure 1-5 As shown, the third window section 6 has a sliding guide rail 12 on the side facing the supporting frame 1, and the sliding rod 11 slides through the sliding guide rail 13. The second window section 5 has a sliding guide rail 13 on the side facing the supporting frame 1. In state one, the stepping rod 10 slides into the sliding guide rail 13. The sliding guide rail 13 includes interconnected docking guide grooves 131 and sliding inclined grooves 132 from top to bottom. The first window section 4 has a stepping guide rail 14 on the side facing the supporting frame 1. In state two and state three, the stepping rod 10 slides into the stepping guide rail 14. The stepping guide rail 14 includes interconnected stepping vertical grooves 141, stepping inclined grooves 142 and docking vertical grooves 143 from top to bottom. The docking vertical grooves 143 are aligned and connected with the docking guide grooves 131.

[0034] like Figure 5-6As shown, the lower end of the first window section 4 is provided with an abutting slope, and a displacement gap is provided between the abutting slope and the upper end of the second window section 5. The upper end of the second window section 5 is provided with an upwardly extending connecting hook 15, and the top of the connecting hook 15 is provided with a downwardly extending connecting hook piece 16. The lower side of the first window section 4 is provided with a connecting hook groove, and the connecting hook piece 16 is hooked and engaged in the connecting hook groove. The second window section 5 is connected to the first window section 4 and the second window section 5 by the connecting hook piece 16 hooking into the connecting hook groove, allowing the second window section 5 to remain synchronized during vertical movement. The upper sidewall of the connecting hook groove is configured as a sliding slope that slides and engages with the connecting hook piece 16. A wedge block 17 is provided on the side of the lower end of the first window section 4 facing the support frame 1. An abutting slope is provided on the side of the wedge block 17 facing the second window section 5. A sliding chamfer is provided on the upper edge of the second window section 5. The abutting slope slides and abuts against the sliding chamfer. The sliding slope slides and engages with the connecting hook piece 16, and the abutting slope slides and engages with the sliding chamfer. This can maintain the smooth sliding of the first window section 4 and the second window section 5 during the translation process of the stepping lever 8 pushing the second window section 5, and avoid jamming.

[0035] like Figure 5 As shown, a wedge-shaped block 18 is provided at the lower end of the second window section 5. A sliding ramp is provided on the side of the wedge-shaped block 18 facing the third window section 6. A sliding chamfer is provided on the upper edge of the third window section 6. The sliding ramp slides and abuts against the sliding chamfer. A displacement gap is provided between the lower end of the third window section 6 and the support of the second window section 5, located behind the sliding ramp. This gap allows the second window section 5 and the third window section 6 to slide smoothly during the translation process of the third window section 6 being pushed by the stepping lever 8, avoiding jamming. A positioning block 19 is provided at the upper end of the second window section 5. A translation block is provided at the lower end of the positioning block 19. The groove, the sliding groove, engages with the upper end of the third window section 6. The lower end of the third window section 6 is provided with a sliding support 20, which engages with the lower end of the second window section 5. The sliding support 20 can support the second window section 5 and limit its movement, so that the sliding roller 22 on the second window section 5 can be aligned with the transverse track 3 to facilitate the subsequent horizontal sliding of the second window section 5. At the same time, the sliding groove of the positioning block 19 engages with the upper end of the third window section 6, so that the second window section 5 and the third window section 6 are connected as one unit, and the second window section 5 and the third window section 6 slide horizontally synchronously.

[0036] The top of the first window section 4 is connected to a transmission mechanism, which includes a lifting motor, a drive shaft, a drive sprocket, a drive chain 21, and a counterweight. The lifting motor is fixed to the support frame 1, the drive shaft is connected to the output end of the lifting motor, the drive sprocket is fixed to the drive shaft, and the drive chain 21 is meshed with the drive sprocket. One end of the drive chain 21 is fixedly mounted on the top of the first window section 4, and the other end is connected to the counterweight.

[0037] Working principle:

[0038] In this invention, when the folding window assembly is opened, the rotation of the lifting motor causes the transmission sprocket connected to the transmission shaft to drive the transmission chain 21 to descend on one side connected to the first window section 4. In state one, the translation rollers 22 on the first window section 4 and the second window section 5 remain in the vertical track 2, preventing relative displacement between the first window section 4 and the second window section 5 in the horizontal direction. Under the weight of the second window section 5, the connecting hook 16 hooks into the connecting hook groove, keeping the first window section 4 and the second window section 5 sliding synchronously. In this state, under the gravity of the first window section 4 and the second window section 5... In the second window section 5, the side wall of the translation groove 132 of the upper translation guide rail 13 presses against the stepping slide rod 10 at the upper end of the stepping lever 8, causing it to slide within the translation groove 132. During the sliding process, the stepping lever 8 rotates around the pivot axis 7, and the push slide rod 11 at the lower end of the stepping lever 8 slides in the stepping guide rail 14 and pushes the third window section 6 to slide along the horizontal track 3 toward the side away from the support frame 1, so that the third window section 6 is horizontally misaligned with the second window section 5 in the vertical direction, allowing the second window section 5 to smoothly slide down and transition to the initial position of the first window section 4. This is state two. The translation roller 22 of the second window section 5 moves to a position directly opposite the horizontal track 3 on the vertical track 2, and the stepping slide rod 10 at the upper end of the stepping lever 8 slides from the docking guide groove 131 into the docking vertical groove 143. The stepping lever 8 completely disengages from the second window section 5. In state two, the lower end of the second window section 5 abuts against the translation support 20, positioning the height of the second window section 5. The translation groove of the positioning block 19 abuts against and engages with the top of the third window section 6, interlocking the second window section 5 and the third window section 6 in the horizontal direction, allowing them to maintain synchronous horizontal sliding. The first window section 4... As the slide continues downward, the stepping slide bar 10 slides along the docking vertical groove 143 of the stepping guide rail 14 into the stepping inclined groove 142. The side wall of the stepping inclined groove 142 presses against the stepping slide bar 10, causing the stepping lever 8 to rotate again. The horizontal push slide bar 11 at the lower end of the stepping lever 8 pushes the third window 6 horizontally again, and the second window 5 and the third window 6 slide horizontally to be completely misaligned, so that the first window 4 can be converted into the third window 6. The above operations can complete the full folding of the folding window assembly, completely opening up the original space of the first window 4 and the second window 5 without encroaching on the interior space.

[0039] When the folding window assembly is closed, the lifting motor rotates, causing the transmission sprocket connected to the transmission shaft to drive the transmission chain 21 to rise on one side of the first window section 4. The side wall of the stepping spur 142 presses against the stepping slide rod 10, causing the stepping lever 8 to rotate in the opposite direction and reset. This resets the second window section 5 and slides it to the initial position of the third window section 6. The translation roller 22 of the second window section 5 slides from the horizontal track 3 to face the vertical track 2. This position is the second state position, and the connecting hook 16 hooks the connecting hook groove, pulling the second window section 5 upward. During the pulling process, the translation guide rail 13 of the second window section 5 presses the stepping lever 8 back to its original position, allowing the third window section 6 to be pulled horizontally to the initial position, realizing the closed state of the folding window assembly and returning to the first state.

[0040] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
