[0043] The following describes two implementation modes of the present application in detail with reference to the accompanying drawings.

[0044] The first implementation method:

[0045] Figure 1-11 An aluminum alloy door and window with anti-theft function is shown, comprising a window frame 1; a built-in anti-theft net 4 is arranged in the window frame 1, and the built-in anti-theft net 4 comprises a mounting frame 7 fixedly connected to the window frame 1, and an annular groove 701 is opened at the inner end of the mounting frame 7, and a pair of winding plates 9 arranged opposite to each other up and down are fixedly connected in the annular groove 701, and a pair of anti-theft ropes 8 symmetrically arranged and cooperated to form a grille net in the mounting frame 7 are passed through the pair of winding plates 9, and one end of the pair of anti-theft ropes 8 is fixedly connected to the winding plate 9 on the lower side, and the other end of the pair of anti-theft ropes 8 extends to the upper side of the winding plate 9 and is connected to a first winding mechanism 10 arranged in the window frame 1, and the first winding mechanism 10 makes the anti-theft rope 8 in a tensioned state or a relaxed state by winding or releasing the anti-theft rope 8;

[0046] A storage mechanism for storing the anti-theft rope 8 in the annular groove 701 is provided in the annular groove 701, and the storage mechanism includes two pairs of traction rings 11 which are respectively slidably connected to the upper and lower inner walls of the annular groove 701 and are arranged between a pair of winding plates 9, and the two pairs of traction rings 11 are arranged in the gap on the opposite side of a pair of anti-theft ropes 8, and the outer end of each traction ring 11 is fixedly connected to a horizontally arranged traction rope 12, and the outer ends of the two pairs of traction ropes 12 are connected to a pair of second winding mechanisms 13 which are symmetrically arranged in the annular groove 701 on the left and right; when storing the anti-theft rope 8, the first winding mechanism 10 releases the pair of symmetrically arranged anti-theft ropes 8, and at the same time, the pair of second winding mechanisms 13 symmetrically arranged on the left and right reel in the two pairs of traction ropes 12, and the two pairs of traction ropes 12 drive the two pairs of traction rings 11 to move to the left and right sides of the installation frame 7 respectively, and the two pairs of traction rings 11 pull and squeeze a pair of anti-theft ropes 8 distributed on the left and right into the annular groove 701.

[0047] For details, please refer to Figure 7-9 When anti-theft is required, the first winding mechanism 10 and the pair of second winding mechanisms 13 are started at the same time, the first winding mechanism 10 reels a pair of symmetrically arranged anti-theft ropes 8, and the pair of second winding mechanisms 13 releases the two pairs of traction ropes 12, and the pair of anti-theft ropes 8 are gradually tightened and finally form a vertical grid-shaped anti-theft net (such as Figure 5 As shown), during the tensioning process, a pair of anti-theft ropes 8 push the two pairs of traction rings 11 to slide horizontally along the annular groove 701 and move to the middle of the installation frame 7;

[0048] When it is necessary to open the anti-theft net formed by the vertical grid-like shape of a pair of tensioned anti-theft ropes 8, the first winding mechanism 10 and the pair of second winding mechanisms 13 are started at the same time, the first winding mechanism 10 releases the pair of anti-theft ropes 8 symmetrically arranged on the left and right, the pair of second winding mechanisms 13 reel in the two pairs of traction ropes 12, and the two pairs of traction rings 11 pull the relaxed pair of anti-theft ropes 8 and store them in the left and right sides of the annular groove 701, thereby realizing the opening and storage of the anti-theft net.

[0049] Compared with the traditional aluminum alloy window, the present invention has a built-in anti-theft net 4 arranged in the window frame 1, and there is no need to install a separate anti-theft net on the outside of the aluminum alloy window. Through a pair of symmetrically arranged anti-theft ropes 8 and a first winding mechanism 10, the pair of symmetrically arranged anti-theft ropes 8 form an anti-theft net in the shape of a vertical grid after being tensioned, thereby realizing the rapid erection of the anti-theft net. Through the storage mechanism including the traction ring 11, the traction rope 12 and the second winding mechanism 13, the pair of anti-theft ropes 8 are quickly pulled and stored, thereby realizing the rapid opening and storage of the anti-theft net, thus overcoming the problem of cumbersome operation of the traditional detachable anti-theft net. After the anti-theft ropes 8 are stored, the aluminum alloy window has a larger viewing field, and is both practical and aesthetic.

[0050] See also Figure 6and Figure 7 The first winding mechanism 10 includes a first winding motor arranged in the window frame 1 and a first winding roller connected to its output shaft for transmission, and one end of a pair of anti-theft ropes 8 close to each other are fixedly connected to the first winding roller and wound around its outer end; the second winding mechanism 13 includes a second winding motor fixedly connected to the inner wall of the annular groove 701 and a pair of second winding rollers distributed up and down and connected to its output shaft, the traction rope 12 is fixedly connected to the second winding roller and wound around its outer end, the second winding motor is a dual-axis motor, and the second winding motor has a pair of output shafts that are symmetrical up and down.

[0051] Specifically, the first winding motor drives the first winding roller to rotate, and the first winding roller winds and releases a pair of anti-theft ropes 8. The traction rope 12 is fixedly connected to the second winding roller and wrapped around its outer end. The second winding motor winds and releases a pair of traction ropes 12 on the same side through a pair of second winding rollers distributed up and down.

[0052] See also Figure 6 and Figure 7 The winding plate 9 is a strip plate and has threading holes 901 equidistantly distributed along its length direction on its surface. The anti-theft rope 8 is S-shaped and moves through the multiple threading holes 901 on a pair of winding plates 9 that are symmetrical in upper and lower directions.

[0053] Specifically, the anti-theft rope 8 is S-shaped and moves through the multiple threading holes 901 on a pair of winding plates 9 that are symmetrical in up and down order, so that the pair of anti-theft ropes 8 form a strip-shaped grid-like anti-theft net in the opening of the installation frame 7.

[0054] See also Figure 6 and Figure 8 The traction ring 11 includes a semicircular ring 1101 and a sliding block 1102 integrally formed therewith. The longitudinal section of the sliding block 1102 is T-shaped. The inner wall of the annular groove 701 is provided with a sliding groove 702 for the sliding block 1102 to slide.

[0055] Specifically, the semicircular ring 1101 of the traction ring 11 has a good pulling and collecting effect on the anti-theft rope 8, and the sliding block 1102 and the sliding groove 702 cooperate to make the traction ring 11 have good stability when moving horizontally.

[0056] See also Figure 2 and Fig.10 The window frame 1 is provided with a first window sash 2 and a second window sash 3 which are slidably connected to the inner wall thereof and are arranged to be opened horizontally. The lower end of the first window sash 2 is connected to a first screw rod module 5 fixed in the window frame 1, and the lower end of the second window sash 3 is connected to a second screw rod module 6 fixed in the window frame 1. Both the first screw rod module 5 and the second screw rod module 6 are electrically connected to the same controller 14;

[0057] The controller 14 is equipped with an anti-theft system, which includes a control module. The input end of the control module is respectively connected to a personnel monitoring module, a window sash monitoring module and a timing module. The input end of the personnel monitoring module is respectively connected to an outdoor human proximity sensor 15 installed at the outer end of the window frame 1 and an indoor human proximity sensor 16 installed on the inner wall of the window frame 1. The outdoor human proximity sensor 15 and the indoor human proximity sensor 16 can sense the presence of a person and the distance between the person and the window frame 1. The input end of the window sash monitoring module is respectively connected to a first distance sensor 19 and a second distance sensor 20 installed on the inner wall of the window frame 1. The first distance sensor 19 and the second distance sensor 20 are respectively used to detect the positions of the first window sash 2 and the second window sash 3; the output end of the control module is respectively connected to a window sash distance adjustment module, a built-in anti-theft net control module and an alarm module. The output end of the window sash distance adjustment module is respectively connected to the first screw module 5 and the second screw module 6, the output end of the built-in anti-theft net control module is respectively connected to the first winding mechanism 10 and the second winding mechanism 13, and the output end of the alarm module is connected to a buzzer 17 installed at the outer end of the window frame 1.

[0058] For details, please refer to Fig.11 The aluminum alloy doors and windows with anti-theft function include the following steps when working:

[0059] Step 1: Start the anti-theft system. The window sash monitoring module detects the opening state of the first window sash 2 and the second window sash 3 through the first distance sensor 19 and the second distance sensor 20. When the first window sash 2 and the second window sash 3 are both in the closed state, the operation is stopped, otherwise, step 2 is executed;

[0060] Step 2: The personnel monitoring module monitors the outdoor personnel outside the window through the outdoor human proximity sensor 15 to detect whether there is an outdoor person and whether the real-time distance between the outdoor person and the aluminum alloy window is less than the warning distance. If there is an outdoor person outside the aluminum alloy window and the real-time distance between the outdoor person and the aluminum alloy window is less than the warning distance, step 3 is executed, otherwise the operation is stopped;

[0061] Specifically, the warning distance is a manually set distance value, and its main criterion is whether the outdoor person is close to the window and has the possibility of climbing the window, which can be set as needed;

[0062] Step 3: Start the timing module to time the time that the outdoor personnel stay in the warning range outside the window. When the time that the outdoor personnel stay in the range less than the warning distance exceeds the set time threshold, execute step 4, otherwise stop the operation;

[0063] Specifically, the retention time threshold is a time value set manually. Long-term retention within the warning distance poses a safety risk, so monitoring and timing are required;

[0064] Step 4: The personnel monitoring module detects the personnel in the room where the aluminum alloy window is located through the indoor human proximity sensor 16. If there is an indoor person in the room, step 5 is executed, otherwise step 6 is executed;

[0065] Step 5: The window sash distance adjustment module adjusts the positions of the first window sash 2 and the second window sash 3 through at least one of the first screw module 5 and the second screw module 6, so that the opening distance of the two window sashes reaches a safe distance, and then executes step 7;

[0066] Specifically, when there are people in the room, there is a certain risk of long-term stay, so the window opening distance is reduced to a safe distance, so that people cannot enter directly through the window opening, improve the anti-theft performance, give people in the room more reaction time, and at the same time, keep the window open for ventilation. In addition, there are also daily situations where indoor and outdoor people are acquaintances and chat around the window. Therefore, the window distance is only adjusted to a safe distance, so that outdoor people cannot directly pass through;

[0067] Step 6: When there is no one in the room, the window sash distance adjustment module closes the first window sash 2 and the second window sash 3 through the first screw rod module 5 and the second screw rod module 6, and then executes step 7;

[0068] Specifically, when there is no one indoors, but people outdoors stay within the warning distance for a long time, there is a greater risk. In order to further reduce the risk, the window sash is directly closed;

[0069] Step 7, obtaining the moving distance and moving time of the window sash through the first distance sensor 19, the second distance sensor 20 and the timing module, the control module calculates the real-time moving speed of the window sash through the moving distance and moving time of the window sash, and then compares the real-time moving speed with the normal moving speed to determine whether the window sash encounters resistance during the closing process, if resistance is encountered, executing step 8, if no resistance is encountered, stopping the operation;

[0070] Specifically, the moving distance of the first window sash 2 and the second window sash 3 during the movement is detected by the first distance sensor 19 and the second distance sensor 20 (the first distance sensor 19 and the second distance sensor 20 are both infrared distance sensors), and the time of movement is recorded in cooperation with the timely module, and then the control module calculates the moving speed of the first window sash 2 and the second window sash 3, and compares the calculated real-time speed value with the normal speed value, wherein the normal speed value is the moving speed of the first window sash 2 and the second window sash 3 when they are normally closed without obstruction. When there are outdoor personnel outdoors and the detention time exceeds the threshold, at the same time, the real-time closing speed of the window sash is less than the normal closing speed. Obviously, the window sash is violently blocked by the outdoor personnel (all devices and sensors work normally. It should be noted that when the control module cannot receive the sensor signal of any monitoring module, the window sash closing operation and the built-in anti-theft net opening operation are automatically started to prevent outdoor personnel from damaging the sensors with tools from a long distance, thereby further improving safety);

[0071] Step eight, start the first winding mechanism 10 and the second winding mechanism 13 through the built-in anti-theft net control module, so that the anti-theft rope 8 is arranged in a vertical grid shape to form an anti-theft net. At the same time, start the buzzer light 17 through the alarm module.

[0072] Specifically, in order to prevent an outdoor person from suddenly trying to break in and block the window sash from closing during the window sash closing process, the built-in anti-theft net 4 is opened for secondary protection, and the buzzer light 17 is started for deterrence.

[0073] Compared with the traditional aluminum alloy window, the present invention is provided with an outdoor human proximity sensor 15 and an indoor human proximity sensor 16 and an anti-theft system including a timing module to monitor the person outside the window and time the person's stay time. When the person stays in the warning distance range outside the window for a long time, the indoor person sensor is used to determine whether there is a person indoors. After comprehensive judgment, the first screw module 5 and the second screw module 5 are used to adjust the window opening distance or directly close the window, so as to improve the anti-theft performance. At the same time, the window is avoided from being directly closed during daily chatting between indoor and outdoor personnel; then the window closing speed is monitored by the first distance sensor 19, the second distance sensor 20 and the timing module, and then it is determined whether there is a possibility of outdoor personnel climbing the window, and then it is decided whether to start the built-in anti-theft net 4, and the built-in anti-theft net 4 is used for secondary protection to further improve the anti-theft performance. In general, a variety of sensors are set to monitor the people inside and outside the window, and different anti-theft strategies (at least one of no operation, closing the window, and opening the built-in anti-theft net 4) are selected according to the actual situation.

[0074] See also Fig.10The anti-theft system also includes an anti-theft mode switch module connected to the control module, the input end of the anti-theft mode switch module is connected to an anti-theft switch button, the anti-theft switch button is fixed on the inner wall of the window frame 1 facing the room, and a window sash opening button is also fixedly connected to the inner wall of the window frame 1 facing the room, and the window sash opening button is connected to the window sash distance adjustment module.

[0075] Specifically, an anti-theft opening and closing button is provided to control whether the anti-theft mode is turned on, thereby avoiding triggering an alarm, automatic movement of the window sash, and opening of the built-in anti-theft net 4 during maintenance; at the same time, a window sash opening button connected to the window sash distance adjustment module is provided to facilitate daily adjustment of the window sash opening distance.

[0077] Figure 2 , Figure 12-13 An aluminum alloy door and window with anti-theft function is shown. Based on the first embodiment, an acoustic wave sensor 18 is fixedly connected to the outer wall of the window frame 1 facing the outdoors. The anti-theft system also includes a acoustic wave monitoring module connected to the input end of the control module, and the input end of the acoustic wave monitoring module is connected to the acoustic wave sensor 18; the acoustic wave characteristics of the demolition are captured by the acoustic wave sensor 18.

[0078] Specifically, the demolition sound waves are captured by the sound wave sensor 18 to determine whether the window has been hit or otherwise damaged. When the sound wave monitoring module receives the demolition sound wave signal sent back by the sound wave sensor 18, the control module immediately starts closing the window sash, starts the built-in anti-theft net 4 and the buzzer light 17, and performs rapid and comprehensive protection. At the same time, it can prevent people from standing outside the warning distance to carry out long-distance damage, and can provide timely protection and alarm. It should be noted that the demolition sound waves include the window frame 1, the frame of the window sash and the specific sound waves emitted by the glass when they are hit.

[0079] See also Fig.12 and Fig.13 The anti-theft system also includes an emergency mode opening and closing module connected to the control module. The input end of the emergency mode opening and closing module is connected to an emergency start button installed on the inner wall of the window frame 1. When the indoor personnel sense that there is danger, they actively press the emergency start button, and the control module directly starts the window sash distance adjustment module and the built-in anti-theft net control module. The window sash distance adjustment module directly closes the first window sash 2 and the second window sash 3 through the first screw rod module 5 and the second screw rod module 6, and the built-in anti-theft net control module opens the built-in anti-theft net through the first winding mechanism 10 and the second winding mechanism 13.

[0080] Specifically, by providing an emergency mode opening and closing module and an emergency start button, it is convenient to actively close the window sashes and set up the built-in anti-theft net 4 in an emergency, thereby improving the timeliness of protection.

[0081] In view of current practical needs, the above-mentioned implementation mode adopted in this application is not limited to the scope of protection. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the scope of protection of the present invention.
