[0001] This application relates to the field of window technology, specifically to an automatic opening and closing window and a cold aisle cabinet. Background Technology

[0002] Currently, ventilation windows or skylights are commonly installed in industrial and warehousing buildings such as factory workshops and warehouses. To meet the needs of ventilation and lighting, these windows are mostly designed with multiple casement windows arranged side by side on the same wall.

[0003] However, this layout presents significant inconveniences in practical use: staff must operate each window individually when opening or closing it, resulting in a heavy workload and low efficiency. Especially in emergencies (such as strong winds, heavy rain, or fires) requiring the emergency closure or opening of numerous windows, the existing method cannot provide a rapid response, leading to low emergency efficiency, potential damage to indoor equipment or goods, and even impacting safe production.

[0023] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0025] In the description of this application, it should also be noted that, unless otherwise expressly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0026] like Figures 1 to 6 As shown, this application provides an automatic opening and closing window 1, including a base 11 and a component disposed on the base 11: At least one base 12, on which a linkage 121 is provided; The drive device 13 includes a drive member 131 and a transmission member 132. The transmission member 132 is connected to the linkage member 121 of each base 12. The transmission member 132 is configured to be driven by the drive member 131 to perform linear reciprocating motion and drive the linkage member 121 to rotate to open or close the base 12. The limiting device 14 and the sensing device 15 are provided. The limiting device 14 is disposed on the base 11 and located at the forward movement end point of the transmission member 132. The sensing device 15 is disposed at the first end of the transmission member 132. The limiting device 14 is used to activate when the transmission member 132 moves to the forward movement end point of the transmission member 132 and connect to the sensing device 15 to fix the transmission member 132. The reset device 16 is disposed on the base 11 and connected to the second end of the transmission member 132. It is used to drive the transmission member 132 to reset to the reverse movement end point of the transmission member 132 when the limit device 14 is closed and the drive member 131 fails.

[0027] The working process of the automatic opening and closing window 1 provided in this embodiment is as follows: 1. The driving component 131 drives the transmission component 132 to move forward to the end point of the forward movement of the transmission component 132, thereby driving the linkage component 121 to rotate and close the base 12. At the same time, the limiting device 14 is activated and the sensing device 15 is detachably connected, so that the base 12 is kept in the closed state (e.g., Figure 1 and Figure 3 (as shown); 2. When the limiting device 14 is closed, the limiting device 14 and the sensing device 15 are separated, and the driving member 131 drives the transmission member 132 to move in the reverse direction to the end point of the reverse movement of the transmission member 132, thereby driving the linkage member 121 to rotate and open the base 12; 3. When the limiting device 14 is closed and the driving member 131 fails, the limiting device 14 and the sensing device 15 are separated, and the transmission member 132 is driven to move in the reverse direction to reset to the end point of the reverse movement of the transmission member 132, thereby opening the base 12.

[0028] The working process of the automatic opening and closing window 1 provided in this embodiment can also be as follows: 1. The driving component 131 drives the transmission component 132 to move forward to the end point of the forward movement of the transmission component 132, thereby driving the linkage component 121 to rotate to open the base 12, and the limiting device 14 is activated and the sensing device 15 is detachably connected, so that the base 12 remains in the open state; 2. When the limiting device 14 is closed, the limiting device 14 and the sensing device 15 are separated, the driving component 131 drives the transmission component 132 to move in the reverse direction to the end point of the reverse movement of the transmission component 132, thereby driving the linkage component 121 to rotate to close the base 12; 3. When the limiting device 14 is closed and the driving component 131 malfunctions, the limiting device 14 and the sensing device 15 are separated, and the transmission component 132 is driven to move in the reverse direction to reset to the end point of the reverse movement of the transmission component 132, thereby closing the base 12.

[0029] Specifically, the base 12 is equipped with a window frame, which is set on the base 11, or the window frame and the base 11 are integrally formed.

[0030] Specifically, the reset device 16 is a pneumatic support rod, but it is not limited to this. The reset device 16 retracts when the transmission member 132 makes a forward movement.

[0031] Specifically, the limiting device 14 is an electromagnet, and the sensing device 15 is a magnetic or magnetically conductive component. When the transmission component 132 moves to the turning point, the limiting device 14 is energized and activated, and magnetically attracts the sensing device 15. The limiting device 14 and the sensing device 15 can also be other detachable connection devices, and are not limited to these.

[0032] Specifically, the drive component 131 is a motor, but it is not limited to this.

[0033] In this embodiment, the transmission component 132 in the drive device 13 performs linear reciprocating motion and drives the base 12 to rotate via the linkage component 121, which can simultaneously realize the opening and closing of multiple bases 12, realize the automation of the opening and closing of the base 12, with high working efficiency, fast response speed, and the ability to quickly deal with emergencies.

[0034] In this embodiment, the limiting device 14 and the sensing device 15 work together to automatically activate and fix the transmission component 132 when the base 12 reaches the fully open or closed position, ensuring that the base 12 remains in the target state (fully open or closed). At the same time, it can resist the state switching of the base 12 caused by external disturbances (such as wind and vibration), thus enhancing safety and durability.

[0035] This embodiment, by setting a reset device 16, realizes the automatic reset of the base 12 in the event of a failure of the drive device 13 or power failure, which significantly improves the fault tolerance and practicality of the base 12 and avoids the safety hazards or inconvenience caused by the window being constantly open or closed due to sudden failure.

[0036] like Figure 2 and Figure 6 As shown, in one embodiment, the automatic opening and closing window 1 further includes a first sensor switch 171, a second sensor switch 172, and a control device 18; The first sensor switch 171 and the second sensor switch 172 are disposed on the base 11. The first sensor switch 171 is used to output a first position signal when the transmission member 132 moves to the end point of the forward movement of the transmission member 132, and the second sensor switch 172 is used to output a second position signal when the transmission member 132 moves to the end point of the reverse movement of the transmission member 132. The control device 18 is connected to the first inductive switch 171, the second inductive switch 172, and the limit device 14 respectively. The control device 18 is used to output a forward drive signal and a reverse drive signal to the drive member 131. It is also used to output an activation signal to the limit device 14 after receiving the first position signal (meaning that the transmission member 132 has reached the forward movement end point of the transmission member 132). It is also used to send a stop signal to the drive member 131 after receiving the first position signal (meaning that the transmission member 132 has reached the forward movement end point of the transmission member 132) and the second position signal (meaning that the transmission member 132 has reached the reverse movement end point of the transmission member 132) so that the drive member 131 stops driving the transmission member 132.

[0037] Specifically, the control device 18 is used to output an activation signal after receiving the first position signal to energize the limit device 14, thereby activating the limit device 14.

[0038] In this embodiment, the actual position of the transmission component 132 is detected by setting a first sensing switch 171 and a second sensing switch 172. When the transmission component 132 has reached the end point of its forward movement, the first sensing switch 171 generates a first position signal. When the transmission component 132 has reached the end point of its reverse movement, the second sensing switch 172 generates a second position signal. In this embodiment, the displacement of the transmission component 132 is converted into a precise electrical signal through the cooperation of the first sensing switch 171 and the second sensing switch 172, providing direct and reliable position feedback for the control device 18 and realizing precise closed-loop control of the opening and closing terminal position of the base 12.

[0039] like Figure 2 As shown, in one embodiment, a transmission seat 133 is provided on the transmission member 132, and the first inductive switch 171 and the second inductive switch 172 are located between the two ends of the transmission seat 133. The transmission base 133 is used to move forward under the drive of the transmission member 132 to contact the first inductive switch 171 so that the first inductive switch 171 outputs a first position signal; the transmission base 132 is also used to move backward under the drive of the transmission member 132 to contact the second inductive switch 172 so that the second inductive switch 172 outputs a second position signal.

[0040] In this embodiment, the first and second sensing switches, representing the forward and reverse motion endpoints of the transmission component 132 respectively, are centrally installed on the same transmission base 133 along its motion path, rather than being dispersed at both ends of the transmission component 132's movement path. This greatly simplifies the sensor layout on the base, saves installation space, and makes the overall structure more compact.

[0041] like Figure 2As shown, in one embodiment, the transmission base 133 is provided with a first contact 1331 and a second contact 1332. The first contact 1331 is used to contact the first inductive switch 171, and the second contact 1332 is used to contact the second inductive switch 172.

[0042] like Figure 6 As shown, in one embodiment, the automatic opening and closing window 1 further includes an alarm device 19, and a control device 18 is signal-connected to the alarm device 19. The control device 18 is used to output a reverse drive signal to the drive member 131, and to output an alarm signal to the alarm device 19 when a preset time is reached and no second arrival signal is received.

[0043] Specifically, the control device 18 includes a timing unit for calculating the time when the control device 18 outputs the reverse drive signal.

[0044] In this embodiment, the control device 18 starts the timing function after sending a reverse drive signal. If the second arrival signal from the target position is not received after the preset time, it is determined to be an abnormal operation or fault (such as transmission jamming, drive failure, serious obstacle blockage, sensor switch failure, etc.), thus realizing fault self-diagnosis. At the same time, it is equipped with an alarm device 19 to realize active alarm and improve the reliability of the device.

[0045] like Figure 4 As shown, in one embodiment, the linkage 121 includes an axial portion 1211 and a rotating portion 1212 connected to each other. The axial portion 1211 is disposed adjacent to the rotating shaft of the base 12, and the rotating portion 1212 is provided with a linkage groove 12121. The linkage groove 12121 forms an angle with the movement direction X of the transmission member. A transmission column 1321 is provided on the transmission component 132. The transmission column 1321 is located in the linkage groove 12121. The transmission column 1321 is used to move under the drive of the transmission component 132 and drive the axial part 1211 to rotate through the linkage groove 12121.

[0046] Specifically, when the transmission column 1321 moves linearly under the drive of the transmission component 132, the side wall of the transmission column 1321 is in continuous contact with the side wall of the linkage groove 12121 and generates an interaction force. This force can be decomposed into an axial force of the linkage groove 12121 and a force perpendicular to the axial direction of the linkage groove 12121. The force perpendicular to the axial direction of the linkage groove 12121 directly drives the rotating part 1212 and the axial part 1211 connected thereto to rotate around the axial part 1211.

[0047] The linkage structure provided in this embodiment, which converts the linear motion of the transmission component 132 into the rotational motion of the axial part 1211, eliminates the need for traditional gears, racks, or complex connecting rods 1323, achieving direct and efficient conversion of motion modes. Furthermore, its simple and compact structure greatly saves installation space and reduces the complexity and manufacturing cost of the mechanism.

[0048] like Figure 4 As shown, in one embodiment, a guide seat 20 is provided on the base 11, the guide seat 20 is disposed adjacent to the base 12, and the guide seat 20 has a guide groove 201, which extends along the movement direction X of the transmission member; the transmission column 1321 passes through the linkage groove 12121 and extends into the guide groove 201, the transmission column 1321 is used to move in the guide groove 201 under the drive of the transmission member 132 and drive the axial part 1211 to rotate through the linkage groove 12121.

[0049] Specifically, the guide seat 20 is provided with a receiving groove, which surrounds the outside of the axial part 1211 to protect the axial part 1211 and extend its service life.

[0050] In this embodiment, the guide groove 201 strictly restricts the movement path of the transmission column 1321, ensuring that the transmission column 1321 can only move along a preset straight path, thus guaranteeing the movement accuracy of the transmission column 1321 itself. For a system with multiple bases 12 linked together, the guide seat 20 ensures that each transmission column 1321 is precisely guided, avoiding the problem of asynchronous movement of the bases 12 caused by the drift of the movement trajectory of one transmission column 1321, and ensuring that all bases 12 open or close synchronously and smoothly.

[0051] like Figure 5 As shown, in one embodiment, the transmission member 132 is provided with one or more threaded segments 1322, the number of threaded segments 1322 being the same as the number of base 12. The transmission column 1321 includes a hollow portion 13211 and a columnar portion 13212. The columnar portion 13212 is located in the linkage groove 12121, and the hollow portion 13211 is fitted onto the threaded segment 1322. The hollow portion 13211 is provided with two fasteners 1325, which are respectively provided on both sides of the hollow portion 13211 and threadedly connected to the threaded segment 1322.

[0052] Specifically, fastener 1325 is a nut.

[0053] In this embodiment, the hollow portion 13211 of the transmission column 1321 corresponding to each base 12 is independently fitted onto a dedicated threaded section 1322. The transmission column 1321 is specifically positioned by fasteners 1325 on both sides. This embodiment allows the transmission column 1321 corresponding to each base 12 to be independently calibrated and fine-tuned, which can effectively compensate for factors such as part machining tolerances, cumulative assembly errors, and uneven mounting surfaces of the base 11, ensuring that all bases 12 achieve a high degree of synchronization during movement.

[0054] like Figure 5 As shown, in one embodiment, the transmission component 132 includes two or more connecting rods 1323. Both ends of the connecting rods 1323 are provided with threaded structures 13231. Two adjacent connecting rods 1323 are provided with relays 1324. The relays 1324 are threadedly connected to the threaded structures 13231 of the two adjacent connecting rods 1323 respectively. The threaded structures 13231 of the two adjacent connecting rods 1323 form a threaded segment 1322.

[0055] Specifically, the relay component is a nut.

[0056] In this embodiment, the transmission component 132 is assembled from multiple connecting rods 1323 with the same structure, so that the total length of the transmission component 132 can be flexibly adjusted according to the actual number of bases 12 that need to be linked. It is suitable for systems with different numbers of bases 12, has excellent versatility and expandability, and meets the diverse needs of the market.

[0057] like Figure 7 As shown, this embodiment also provides a cold aisle cabinet, including a cabinet body 2 and an automatic opening / closing window 1 as described in any of the above embodiments (e.g., Figures 1 to 6 As shown in the figure, the automatic opening and closing window 1 is installed on the cabinet body 2.

[0058] In one embodiment, the base 11 of the automatic opening and closing window 1 is mounted on the cabinet body 2.

[0059] In one embodiment, the base 11 of the automatic opening and closing window 1 is integrated with the cabinet body 2.

[0060] In one embodiment, the automatic opening and closing window 1 is located on the side of the cabinet body 2, and the automatic opening and closing window 1 constitutes the side window of the cold aisle cabinet.

[0061] In one embodiment, the automatic opening and closing window 1 is located on the top of the cabinet body 2, and the automatic opening and closing window 1 constitutes the skylight of the cold aisle cabinet.
