Description

Technical Field

[0001] This utility model relates to facilities for raising captive animals, and more particularly to an automatic switching device. Background Technology

[0002] In the management of captive animals, the opening and closing of enclosure doors is an important and frequent operation. Currently, the opening and closing devices commonly available on the market have many shortcomings.

[0003] Most animal enclosures use manually operated sliding doors. These doors require manual operation to open and close, making them extremely inconvenient. Keepers must physically go to the door to push and pull it, and due to the demands of daily tasks, it's easy to forget to open or close the door. For example, forgetting to open the door on time can prevent animals from accessing food, water, or play area; forgetting to close the door can allow animals to escape, causing financial losses or other safety hazards.

[0004] Most existing automatic switching devices use drive components to push linkage assemblies to make the enclosure door rotate relative to the enclosure body to open and close the entrance for animals to enter and exit. This results in automatic switching devices occupying a large space, and the linkage assembly contains many moving parts, making the structure of the automatic switching device complex, increasing the difficulty of installation, and also placing high requirements on the installation space, making it difficult to install and use in some enclosures with limited space or special layouts. Utility Model Content

[0005] In view of this, one objective of this utility model is to provide an automatic switching device to solve the technical problems of existing automatic switching devices occupying a large space and having a large number of moving parts in their linkage assembly, which makes the automatic switching device structurally complex, increases the difficulty of installation, and places high demands on the installation space, making it difficult to install and use in some confined or specially laid-out enclosures.

[0006] This utility model provides an automatic switching device applied to a captive animal shed. The automatic switching device includes a door frame, door panels, a transmission component, a drive component, a position detector or a cut-off switch, and a main control board. The door frame is installed on the captive animal shed. The door panels are movably installed on the door frame. The transmission component is installed on the door frame and is drively connected to the door panels. The drive component is installed on the door frame and is drively connected to the transmission component, and is used to drive the transmission component to move the door panels relative to the door frame to open or close the passageway of the captive animal shed. The position detector is disposed on the door frame and is used to generate a sensing signal when at least one door panel is detected to have moved to the closed position relative to the door frame; the cut-off switch is disposed on the door frame and is used to cut off the power circuit connected to the drive component when at least one door panel is moved to the closed position relative to the door frame. The main control board is connected to the position detector or the cut-off switch. The main control board is used to receive the sensing signal detected by the position detector or to receive the power cut-off signal sent by the cut-off switch, and to control the drive component to stop working according to the sensing signal or the power cut-off signal.

[0007] In some implementations, the door frame includes a first horizontal beam and two vertical beams, the two vertical beams being connected to both ends of the first horizontal beam respectively. The position detector or the cut-off switch is disposed at at least one end of the first horizontal beam in the translational direction of the door panel. When at least one door panel moves relative to the door frame to the closed position, the door panel that has moved to the closed position presses against the position detector or the cut-off switch.

[0008] In some implementations, all the door panels and the door frame are stacked on top of each other in the thickness direction of the door panels; the automatic switching device further includes a limiting structure disposed on the door frame and / or the door panel, and used to limit the movement of the door panel relative to the door frame along the thickness direction of the door panel.

[0009] In some implementations, the limiting structure includes a first limiting body and a second limiting body. The first limiting body is installed on the door panel and stops the door frame in the thickness direction of the door panel.

The door panel is limited between the first limiting body and the second limiting body.

[0010] In some implementations, the transmission component includes a transmission gear and a rack, the transmission gear being connected to the drive component, the rack meshing with the transmission gear and being fixedly connected to the door panel.

[0011] In some implementations, the door panel is configured as two panels, which are connected to the door frame to form a double-door structure. Two racks are provided. The transmission gear includes a main drive gear and a driven gear. The main drive gear is connected to the drive component, and the driven gear meshes with the main drive gear. One door panel meshes with the main drive gear via one of the racks, and the other door panel meshes with the driven gear via the other rack. Alternatively, the transmission gear includes a main drive gear and two driven gears. The main drive gear is connected to the drive component, and both driven gears mesh with the main drive gear and with the two door panels via corresponding racks. Alternatively, the transmission gear includes two main drive gears, which are connected to different drive components and mesh with the two door panels via corresponding racks.

[0012] In some implementations, the transmission component includes a pulley, a belt, and a connecting block. The pulley is connected to the drive component, the belt is rotatably disposed around the outside of the pulley, one end of the connecting block is fixedly connected to the belt, and the other end of the connecting block is fixedly connected to the door panel.

[0013] In some implementations, the door panel is configured as two panels, which are connected to the door frame to form a double door structure. Two connecting blocks are configured, and the two door panels are respectively fixedly connected to the belt through the two connecting blocks.

[0014] In some implementations, the door panel is provided with a sliding groove, the extension direction of which is parallel to the translation direction of the door panel, and the automatic switching device further includes a sliding structure, which is disposed on the door frame and slides in cooperation with the sliding groove.

[0015] In some implementations, the door panel is configured as two panels, which are connected to the door frame to form a double door structure. The two door panels are staggered in the direction of entry and exit of the passage. The driving component is used to drive the transmission component to move the two door panels relative to the door frame in opposite directions.

[0016] In some implementations, the automatic switching device further includes a first guide rail and a second guide rail, which protrude from the sidewall of the door frame facing the door panel and are respectively used to abut against the two door panels. In some implementations, the automatic switching device further includes a current detection module and a main control board. The current detection module is electrically connected to the main control board and is used to monitor the current data of the driving component and transmit the current data to the main control board. When the current data exceeds a preset current range, the main control board controls the driving component to stop rotating in the forward direction, and after the driving component stops, controls the driving component to rotate a preset distance in the opposite direction to the forward direction.

[0017] In some implementations, when the two door panels close the passageway, the orthographic projection of the two door panels in the direction perpendicular to the thickness of the door panels lies within the orthographic projection of the door frame in the direction of the thickness of the door panels.

[0018] In some implementations, the door frame is provided with a load-bearing structure, and the door panel includes a door panel body and an extension plate. The extension plate is connected to the side of the door panel body in the translational direction of the door panel and is disposed between the transmission component and the load-bearing structure.

[0019] In some implementations, the supporting structure extends along the thickness direction of the door panel, and a partition strip is provided on the side wall of the supporting structure, with the two door panels located on both sides of the partition strip in the thickness direction of the door panel; or, two limiting grooves are provided on the side wall of the supporting structure, and the two limiting grooves are spaced apart in the thickness direction of the door panel, with the two door panels located in the two limiting grooves respectively.

[0020] In some implementations, the door panel further includes a bending plate, which is bent and connected to the side of the door panel body near the extension plate in the translational direction of the door panel. When the two door panels close the passageway, the two bending plates abut against each other.

[0021] In some implementations, the door panel body and the extension plate are connected to form an avoidance notch, wherein the avoidance notch of one of the door panels is used to avoid the door panel body of another door panel.

[0022] In some implementations, the extension plate has a positioning notch on the side facing away from the door panel body, and the positioning notch engages with the sliding structure when the door panel closes the passage.

[0023] In some implementations, the load-bearing structure is rotatable relative to the door frame; or, the load-bearing structure is fixed relative to the door frame.

[0024] In some implementations, the automatic switching device further includes a protective housing and a main control board electrically connected to the drive component. The protective housing is installed on the door frame and covers the outside of the main control board, the drive component, and the transmission component.

[0025] In some implementations, the automatic switching device further includes an energy storage component, which is electrically connected to the main control board and the drive component, and the protective housing covers the outside of the energy storage component.

[0026] The automatic switching device provided by this utility model, on the one hand, is based on installing a transmission component on the door frame and driving it to the door panel, and installing a drive component on the door frame and driving it to the transmission component. The drive component can drive the transmission component to open or close the door panel to the entrance of the enclosure. Thus, the automatic switching device can automatically control the opening or closing of the door panel to the entrance of the enclosure, improving the efficiency and safety of captive animal management. It simplifies the structure of the automatic switching device, reduces the installation difficulty of each component and the requirements for installation space, thereby enabling the automatic switching device to adapt to more installation scenarios, improving the adjustability of its usage state, and enhancing the user experience for animal keepers. On the other hand, the drive component can drive the transmission component to move the door panel relative to the door frame, thus not occupying the door panel's opening radius. This makes it suitable for places with limited space. Furthermore, the door panel can fit tightly against the door frame when the passage is closed, giving the automatic opening and closing device good sound insulation, sealing, and wind resistance. It also prevents the door panel from falling uncontrollably in the vertical direction and injuring animals, thus improving the safety of the automatic opening and closing device. In addition, the main control board can control the drive component to stop working based on the sensing signal sent by the position detector or the power cut-off signal sent by the cut-off switch, thereby reducing damage to the drive component and preventing the door panel from colliding or being damaged by excessive translation.

[0045] Please refer to the following: Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the automatic switching device 300 provided in the first embodiment of the present invention installed in the captive breeding shed 100; Figure 2 yes Figure 1 A partial structural diagram of the back of the automatic switch device 300 in the open state; Figure 3 yes Figure 1A partial structural diagram of the automatic switching device 300 in the open state is shown on the front. The automatic switching device 300 is applied to the enclosure 100. The automatic switching device 300 includes a door frame 1, at least one door panel 5, a transmission component 30, a position detector 18, and a drive component 2. The door frame 1 is mounted on the enclosure 100. At least one door panel 5 is movably mounted on the door frame 1. The transmission component 30 is mounted on the door frame 1 and is drively connected to the at least one door panel 5. The drive component 2 is mounted on the door frame 1 and is drively connected to the transmission component 30. The drive component 2 is used to drive the transmission component 30 to move the at least one door panel 5 relative to the door frame 1, thereby opening or closing the passage opening 1001 of the enclosure 100. The position detector 18 is disposed on the door frame 1 and is used to generate a sensing signal when it detects that at least one of the door panels 5 has moved to the closed position relative to the door frame 1. The main control board 11 is connected to the position detector 18. The main control board 11 is used to receive the sensing signal detected by the position detector 18 and control the drive component 2 to stop working according to the sensing signal.

[0046] In some embodiments, the position detector 18 can be replaced by a cut-off switch. Specifically, the automatic switching device 300 includes a door frame 1, at least one door panel 5, a transmission component 30, a cut-off switch, and a drive component 2. The door frame 1 is mounted on the enclosure 100. At least one door panel 5 is movably mounted on the door frame 1. The transmission component 30 is mounted on the door frame 1 and is drively connected to the at least one door panel 5. The drive component 2 is mounted on the door frame 1 and is drively connected to the transmission component 30. The drive component 2 is used to drive the transmission component 30 to move the at least one door panel 5 relative to the door frame 1 in a translational motion to open or close the passage opening 1001 of the enclosure 100. The cut-off switch is disposed on the door frame 1 and is used to cut off the power circuit connected to the drive component 2 when the at least one door panel 5 moves to the closed position relative to the door frame 1. The main control board 11 is connected to the cut-off switch. The main control board 11 is used to receive the power cut-off signal sent by the cut-off switch and to control the drive component 2 to stop working according to the power cut-off signal.

[0047] The automatic switching device 300 provided by this utility model, on the one hand, is based on the installation of a transmission component 30 on the door frame 1 and its transmission connection to the door panel 5, and the installation of a drive component 2 on the door frame 1 and its transmission connection to the transmission component 30. The drive component 2 can drive the transmission component 30 to drive the door panel 5 to open or close the passage opening 1001 of the enclosure 100. Thus, the automatic switching device 300 can automatically control the door panel 5 to open or close the passage opening 1001 of the enclosure 100, improving the efficiency and safety of captive animal management, simplifying the structure of the automatic switching device 300, and reducing the installation difficulty of each component and the requirements for installation space. This allows the automatic switching device 300 to adapt to more installation scenarios, improves the adjustability of its usage state, and enhances the feeding efficiency. On the one hand, the driving component 2 can drive the transmission component 30 to move the door panel 5 relative to the door frame 1, thus not occupying the opening radius of the door panel 5, making it suitable for places with limited space. Furthermore, the door panel 5 can fit tightly against the door frame 1 when the passage 1001 is closed, so that the automatic switch device 300 has good sound insulation, sealing, and wind resistance performance, and avoids the problem of the door panel 5 falling uncontrollably in the vertical Y direction and injuring animals, thus improving the safety of the automatic switch device 300. On the other hand, the main control board 11 can control the driving component 2 to stop working according to the sensing signal sent by the position detector 18 or the power cut-off signal sent by the cut-off switch, thereby reducing the damage to the driving component 2 and avoiding the problem of the door panel 5 colliding or being damaged by the door frame 1 due to excessive translation.

[0048] A pen shed 100 refers to a closed or semi-closed facility used for the centralized feeding and management of animals, commonly found in animal husbandry and aquaculture. Animals can be, but are not limited to, chickens, ducks, rabbits, cattle, sheep, etc. A pen shed 100 can be, but is not limited to, chicken houses, duck houses, rabbit houses, cattle houses, sheep houses, etc. Understandably, to enable those skilled in the art to better understand the automatic switching device 300, the first embodiment of this utility model uses the application of the automatic switching device 300 in a chicken house as an example for detailed description. It should be noted that the application scenario of the automatic switching device 300 in a chicken house is for illustrative purposes only, and this utility model does not impose specific limitations; the application scenario type of the automatic switching device 300 can be set according to actual needs.

[0049] For example, in this embodiment, the enclosure 100 may include an enclosure body 102 and an enclosure cover 104 covering the enclosure. The enclosure body 102 may be, but is not limited to, a wall or fence. At least one of the enclosure body 102 and the enclosure cover 104 is provided with a ventilation window 106, thereby promoting the exchange of indoor and outdoor air in the enclosure 100, keeping the air fresh, and improving the living comfort of the animals. Of course, in some embodiments, the enclosure 100 may omit the enclosure cover 104, that is, the enclosure 100 may only include the enclosure body 102.

[0050] For the sake of accuracy, all references to direction in this article should be expressed in terms of direction. Figure 1 For reference, the term "horizontal direction X" refers to any direction within the bearing surface of the automatic switch device 300, i.e., the left-right direction. The bearing surface is a surface parallel to the horizon and perpendicular to the direction of gravity of the automatic switch device 300. The term "vertical direction Y" refers to the direction perpendicular to the bearing surface of the automatic switch device 300, i.e., the up-down direction. The horizontal direction X and vertical direction Y together constitute the two orthogonal directions of the automatic switch device 300. For ease of description, the horizontal direction X and vertical direction Y in this utility model are relative positions and do not constitute a limitation. The horizontal direction X and vertical direction Y can be customized according to the specific structure of the product and the viewing angle presented in the accompanying drawings; this utility model does not impose specific limitations.

[0051] For example, in this embodiment, the driving component 2 drives the transmission component 30 to move the door panel 5 relative to the door frame 1 in a horizontal direction X, thereby preventing the door panel 5 from falling under gravity and injuring animals or keepers when the automatic control device is out of control, thus improving the safety of the automatic control device. In other words, the translation direction of the door panel 5 is parallel to the horizontal direction X. Of course, in some embodiments, the driving component 2 drives the transmission component 30 to move the door panel 5 relative to the door frame 1 in a vertical direction Y. In other words, the translation direction of the door panel 5 is parallel to the vertical direction Y.

[0052] It should be noted that, Figure 2 The purpose is merely to schematically describe the arrangement of the door frame 1, door panel 5, transmission component 30 and drive component 2, and is not to specifically limit the connection position, connection relationship and specific structure of each component. Figure 2 This illustration of the automatic switching device 300 in an embodiment of the present invention is merely a structural representation and does not constitute a specific limitation on the automatic switching device 300. In other embodiments of the present invention, the automatic switching device 300 may include... Figure 2The automatic switch 300 may include, but is not limited to, a communication module, a protection module, etc., with more or fewer components, or combinations of certain components, or different components. The communication module can receive commands from mobile devices. Mobile devices may be, but are not limited to, mobile phones, computers, remote controls, etc. Commands may be door-opening commands or door-closing commands. The protection module is installed on the door panel 5. The protection device may be, but is not limited to, rubber, sponge, etc., to prevent the door panel 5 from scratching animals.

[0053] For example, in this embodiment, the vertical distance between the door panel 5 and the ground is less than the vertical distance between the door frame 1 and the ground, thereby reducing the friction between the door panel 5 and the ground, improving the smoothness and reliability of the translational movement of the door panel 5 relative to the door frame 1, and reducing the pollution of the door panel 5 by animal excrement.

[0054] The door frame 1 is fixed to the edge of the passageway 1001 of the enclosure 100. Exemplarily, in this embodiment, the door frame 1 is detachably connected to the enclosure 100, thereby facilitating the assembly, maintenance, and replacement of the automatic switching device 300. Of course, in some embodiments, the door frame 1 and the enclosure 100 can also be integrally formed; this embodiment of the present invention does not impose specific limitations.

[0055] The door frame 1 is provided with an entrance 101 that communicates with the passageway 1001. Exemplarily, in this embodiment, the door frame 1 includes a first horizontal beam 110, a second horizontal beam 120, and two vertical beams 130. The first horizontal beam 110, the second horizontal beam 120, and the two vertical beams 130 are connected to form the entrance 101, thereby enabling animals or keepers to enter and exit the enclosure 100. Specifically, one end of each of the two vertical beams 130 is connected to both ends of the first horizontal beam 110, and the other end of each of the two vertical beams 130 is connected to both ends of the second horizontal beam 120, thereby improving the overall structural strength of the door frame 1 and thus enhancing the stability and reliability of the connection between the door frame 1 and the enclosure 100. Of course, in some embodiments, the second horizontal beam 120 may be omitted, meaning the door frame 1 only includes the first horizontal beam 110 and the two vertical beams 130.

[0056] The first crossbeam 110 is located above the second crossbeam 120, and the drive component 2 and transmission component 30 are disposed on the first crossbeam 110. Therefore, on the one hand, it prevents animals or keepers from accidentally activating the drive component 2, reducing the safety hazards of the automatic switch device 300, and reducing the corrosion of electrical components such as the drive component 2 by ground dust, moisture, and feces, thus extending the service life of the automatic switch device 300; on the other hand, it reduces the space occupied by the automatic switch device 300, avoiding interference with animal activities. Of course, in some embodiments, the drive component 2 and transmission component 30 may also be disposed on the second crossbeam 120, or a door frame 1 may be provided between the first crossbeam 110 and the second crossbeam 120; this embodiment of the present invention does not impose specific limitations.

[0057] Specifically, the drive component 2 and the transmission component 30 are located in the middle of the first crossbeam 110, thereby improving the uniformity of force distribution on the first crossbeam 110 and shortening the distance the door panel 5 moves relative to the door frame 1, resulting in a compact structure. The door frame 1 serves as the supporting structure for the drive component 2 and the transmission component 30. The material of the door frame 1 may include, but is not limited to, at least one of steel, wood, alloys, etc. For example, in this embodiment, the door frame 1 is made of steel, which gives the door frame 1 advantages such as sturdiness, durability, fire resistance, and ease of maintenance and cleaning.

[0058] In the first embodiment, the transmission component 30 is configured as a gear transmission component. The transmission component 30 includes a transmission gear 31 and a rack 6. The transmission gear 31 is connected to the drive component 2, and the rack 6 meshes with the transmission gear 31 and is fixedly connected to the door panel 5. Thus, based on the meshing transmission of the transmission gear 31 and the rack 6, the door panel 5 is driven to open or close the passage opening 1001. On the one hand, the meshing transmission of the transmission gear 31 and the rack 6 can reduce vibration and impact, improve the smoothness and accuracy of the movement of the door panel 5 relative to the door frame 1, and extend the service life of the automatic opening and closing device 300. On the other hand, the transmission gear 31 and the rack 6 have a simple structure, are easy to maintain, and can withstand large loads. Furthermore, the transmission efficiency of the transmission gear 31 and the rack 6 is high, reducing energy loss and lowering operating costs. In addition, the transmission gear 31 and the rack 6 can be designed to have a self-locking function to prevent the door panel 5 from moving accidentally relative to the door frame 1, thereby improving the safety of the automatic opening and closing device 300.

[0059] For example, in this embodiment, the rack 6 and the door panel 5 are integrally formed, thereby enhancing the connection strength and stability between the rack 6 and the door panel 5, reducing the risk of failure due to loose connections, and improving the overall performance and service life of the door panel 5. Of course, in some embodiments, the rack 6 and the door panel 5 are independently arranged and fixedly connected, thereby reducing the processing difficulty of the rack 6 and the door panel 5 and facilitating maintenance. The door panel 5 is made of a high-strength material with a smooth surface to prevent scratches from animals such as cattle and sheep.

[0060] The door panel 5 is configured as two panels, which are connected to the door frame 1 to form a double-door structure. Two racks 6 are also configured. Therefore, firstly, the simultaneous opening of both door panels 5 provides a wider passageway 1001, facilitating the rapid evacuation of chickens or personnel; secondly, it shortens the distance each door panel 5 moves relative to the door frame 1, improving the overall compactness of the automatic opening and closing device 300.

[0061] The two door panels 5 are staggered in the direction of entry and exit of the passage 1001. The driving component 2 drives the transmission component 30 to move the two door panels 5 in opposite directions relative to the door frame 1. Thus, on the one hand, by using the same driving component 2 to drive the transmission component 30 to move both door panels 5 simultaneously, costs are saved, the number of components is reduced, assembly is facilitated, and the maintenance difficulty of the automatic switching device 300 is lowered. On the other hand, the staggered arrangement of the two door panels 5 in the direction of entry and exit of the passage 1001 avoids collisions, scratches, and wear when the two door panels 5 move relative to the door frame 1, improving the smoothness and reliability of the translational movement of the two door panels 5.

[0062] In some embodiments, when the two door panels 5 close the passage opening 1001, the orthographic projection of the two door panels 5 in the direction perpendicular to the thickness of the door panels 5 lies within the orthographic projection of the door frame 1 in the direction of the thickness of the door panels 5. Therefore, when the two door panels 5 close the passage opening 1001, the problem of the door panels 5 protruding relative to the door frame 1 and being damaged by the zookeeper, or causing the zookeeper to be scratched and injured, is avoided.

[0063] The transmission gear 31 includes a main drive gear 3 and a driven gear 4. The main drive gear 3 is connected to the drive component 2, and the driven gear 4 meshes with the main drive gear 3. One door panel 5 meshes with the main drive gear 3 via one of the racks 6, and the other door panel 5 meshes with the driven gear 4 via another rack 6. Thus, the main drive gear 3 and the driven gear 4 are configured as one unit, thereby improving the synchronization of the movement of the two door panels 5 relative to the door frame 1, reducing the number of components in the transmission gear 31, saving costs, and improving structural compactness. The two door panels 5 are symmetrically arranged relative to the door frame 1, thereby improving the visual aesthetics of the automatic opening and closing device 300, suitable for modern chicken coops. Of course, in some embodiments, the two door panels 5 are asymmetrically arranged relative to the door frame 1.

[0064] In some embodiments, the transmission gear 31 includes a main drive gear 3 and two driven gears 4. The main drive gear 3 is connected to the drive component 2, and the two driven gears 4 mesh with the main drive gear 3 and with the two door panels 5 via corresponding racks 6. This simplifies installation and debugging, saving time and manpower.

[0065] In other embodiments, the transmission gear 31 includes two main drive gears 3, which are connected to different drive components 2 and mesh with the two door panels 5 via corresponding racks 6. Thus, on the one hand, one or both door panels 5 can be controlled to move relative to the door frame 1 as needed, improving usability; on the other hand, if one drive component 2 fails, the other drive component 2 can still operate, facilitating maintenance and repair. The two drive components 2 share the load, resulting in smoother operation and reduced vibration and noise.

[0066] Of course, in some other embodiments, the door panel 5 can also be a single door, and the transmission gear 31 can also include only the main drive gear 3. The number of the main drive gear 3 and the driven gear 4 can be set according to the actual situation, and this embodiment does not make specific limitations.

[0067] Please refer to the following: Figure 3 and Figure 4 , Figure 4 yes Figure 1 The diagram shows the front view of the automatic switch device 300 in its open state. In some embodiments, the automatic switch device 300 further includes a protective housing 17 and a main control board 11 electrically connected to the drive component 2. The protective housing 17 is mounted on the door frame 1 and covers the main control board 11, the drive component 2, and the transmission component 30. The protective housing 17 protects the main control board 11, the drive component 2, and the transmission component 30, preventing external dust, moisture, feces, and other debris from entering the inner cavity of the protective housing 17 and causing corrosion to the electrical components such as the main control board 11 and the drive component 2, and preventing debris from hindering the transmission movement of the transmission component 30 and the door panel 5. This extends the service life of the automatic switch device 300 and improves the reliability and stability of its operation.

[0068] Please refer to the following: Figure 4 and Figure 5 , Figure 5 yes Figure 1The diagram shows the side view of the automatic switch device 300 in the open state. Specifically, at least one sidewall of the protective housing 17 in the translational direction of the door panel 5 has a movable opening 1701 on the side near the door frame 1. The door panel 5 is movably inserted through the movable opening 1701, thereby realizing the translational movement of the door panel 5 relative to the door frame 1. In some embodiments, the door panel 5 and the movable opening 1701 are slidably engaged, that is, the door panel 5 and the protective housing 17 are slidably abutted against each other. Therefore, on the one hand, the movable opening 1701 can guide the translational movement of the door panel 5; on the other hand, when the door panel 5 closes the passage opening 1001, the door panel 5 can block the movable opening 1701, thereby preventing external dust, moisture, feces, and other debris from entering the inner cavity of the protective shell 17 and causing corrosion to electrical components such as the main control board 11 and drive component 2, and preventing debris from hindering the transmission movement of the transmission component 30 and the door panel 5. This extends the service life of the automatic switch device 300 and improves the reliability and stability of the automatic switch device 300. Of course, in some embodiments, the door panel 5 and the protective shell 17 are spaced apart at the movable opening 1701, thereby reducing the friction between the door panel 5 and the protective shell 17 and reducing noise. The number of movable openings 1701 corresponds one-to-one with the number of door panels 5. For example, in this embodiment, there are also two movable openings 1701. In other words, each sidewall of the protective shell 17 in the translational direction of the door panel 5 is provided with a movable opening 1701 on the side closer to the door frame 1.

[0069] Please refer to the following: Figure 6 and Figure 7 , Figure 6 yes Figure 1 An exploded view of the automatic switching device 300 in the diagram; Figure 7 yes Figure 1The diagram illustrates the contact between the door panel 5 and the position detector 18 of the automatic switching device 300. Exemplarily, in this embodiment, the position detector 18 is disposed on the first crossbeam 110 of the door frame 1 and is used to generate a sensing signal when the door panel 5 is detected to have moved relative to the door frame 1 to the closed position. Specifically, the position detector 18 is disposed at at least one end of the first crossbeam 110 in the translational direction of the door panel 5. When at least one door panel 5 moves relative to the door frame 1 to the closed position, the door panel 5 that has moved to the closed position presses against the position detector 18. At this time, the position detector 18 can generate a sensing signal and send the sensing signal to the main control board 11. For example, the position detector 18 is configured as a single unit, located at one end of the first crossbeam 110 in the translational direction of the door panel 5. Therefore, when the door panel reaches the position where it has moved to the closing passage 1001, the door panel 5 presses against and triggers the position detector 18 to generate a sensing signal. The main control board 11 then controls the drive component 2 to stop operating based on the sensing signal. The closing position refers to the position where the door panel 5 relative to the door frame 1 reaches the closing passage 1001. Thus, when the door panel 5 is detected to have reached the closing position relative to the door frame 1, it indicates that the door panel 5 has closed the passage 1001, thereby improving the accuracy and reliability of the translational movement of the door panel 5 relative to the door frame 1, avoiding damage caused by excessive movement of the door panel 5 relative to the door frame 1, and improving the safety of the automatic switching equipment. The position detector 18 can be, but is not limited to, a mechanical electronic switch, photoelectric encoder, magnetic encoder, laser rangefinder, ultrasonic sensor, etc. The position detector 18 is configured as a single unit and located at one end of the first crossbeam 110. In other embodiments, two position detectors 18 may be configured, with each door panel 5 contacting the position detector 18 after moving to the closed position, thereby improving the reliability of the door panel 5 closing the passage opening 1001. Of course, in some embodiments, the position detector 18 is located at the middle position of the first crossbeam 110 in the translational direction of the door panel 5, and this utility model does not make specific limitations.

[0070] It should be noted that the location of the cut-off switch can be the same as or different from the location of the position detector 18. For example, the cut-off switch can also be located at at least one end of the first beam in the translational direction of the door panel. When at least one of the door panels 5 moves to the closed position relative to the door frame 1, the door panel 5 in the closed position presses against the cut-off switch, thereby disconnecting the power circuit between the drive component 2 and the power source. The main control board 11 can receive the power cut-off signal sent by the cut-off switch and control the drive component 2 to stop working according to the power cut-off signal. Thus, since the power circuit between the drive component 2 and the power source is cut off, the drive component 2 cannot work. When the user triggers the automatic switch device 300 again to open the passage 1001, the cut-off switch connects the power circuit between the drive component 2 and the power source, thereby enabling the drive component 2 to drive the transmission component 30 to move at least one of the door panels 5 relative to the door frame 1 to open the passage 1001.

[0071] For example, in this embodiment, the position detector 18 is configured as a mechanical electronic switch. The working principle of a mechanical electronic switch is to open or close the switch contacts using mechanical or magnetic force, thereby opening or closing the circuit. The mechanical electronic switch uses a micro switch. It should be noted that a micro switch is a contact mechanism with a small contact gap and a quick-acting mechanism, which performs switching action with a specified stroke and specified force. It is covered by a housing and has a drive rod on the outside. Because its contact gap is relatively small, it is called a micro switch, also known as a sensitive switch.

[0072] Please refer to it again. Figure 3 and Figure 6 In some embodiments, the automatic switching device 300 further includes a current detection module 111 and a main control board 11. The current detection module 111 is electrically connected to the main control board 11 and is used to monitor the current data of the drive component 2 and transmit the current data to the main control board 11. When the current data exceeds a preset current range, the main control board 11 controls the drive component 2 to stop rotating in the forward direction, and after the drive component 2 stops, controls the drive component 2 to rotate a preset distance in the opposite direction to the forward direction. Thus, the current detection module 111 can provide an anti-pinch function for the automatic switching device 300, reducing the risk of animals being pinched and providing reliable safety for captive animals. Specifically, during the closing process, if the door panel 5 pinches an animal, the current detection module 111 can quickly detect an abnormal increase in the current of the drive component 2 and accurately transmit the abnormal signal to the main control board 11. The main control board 11 then controls the drive component 2 to stop operating and reverse a preset direction based on the abnormal signal, thereby creating an opportunity for the animal to escape.

[0073] It should be noted that the preset travel distance can be the distance the door panel 5 moves relative to the door frame 1 to the fully opened passageway 1001; or, it can be the distance the door panel 5 moves relative to the door frame 1 to the partially opened passageway 1001. After the main control board 11 controls the drive component 2 to rotate in the opposite direction to the forward rotation direction for a preset travel distance and a preset time, if the current data of the drive component 2 is within a preset current range, the main control board 11 controls the drive component 2 to rotate in the forward rotation direction until the door panel 5 moves to the closed position. This achieves automatic continuation of the closing action of the automatic switch device 300, improving usability. Of course, in some embodiments, after the main control board 11 controls the drive component 2 to rotate in the opposite direction to the forward rotation direction for a preset travel distance and a preset time, the drive component 2 stops working, and only resumes rotation in the forward rotation direction until the door panel 5 moves to the closed position after receiving a closing command from the zookeeper.

[0074] Please refer to it again. Figure 3 and Figure 6 In some embodiments, the door panel 5 is provided with a sliding groove 7. The extending direction of the sliding groove 7 is parallel to the translational direction of the door panel 5. The automatic switching device 300 also includes a sliding structure 8, which is disposed on the door frame 1 and slidably engages with the sliding groove 7. Thus, the sliding groove 7 and the sliding structure 8 can restrict the door panel 5 from moving relative to the door frame 1 in the vertical direction Y, thereby improving the accuracy and reliability of the door panel 5's translational movement relative to the door frame 1 in the horizontal direction X. Specifically, the top of the door panel 5 is provided with a sliding groove 7, and the door frame 1 is equipped with a sliding structure 8 at the position corresponding to the sliding groove 7. The sliding groove 7 and the sliding structure 8 cooperate to restrict the door panel 5 from displacing relative to the door frame 1 in the vertical direction Y.

[0075] The sliding structure 8 is rotatably configured relative to the door frame 1. In this embodiment, the sliding structure 8 is configured as a bearing, thereby reducing friction and vibration between the door panel 5 and the door frame 1, reducing noise generated by the automatic switching device 300 during operation, and improving the stability and reliability of the horizontal translation of the door panel 5 relative to the door frame 1. Of course, the sliding structure 8 can also be configured as a roller.

[0076] Of course, in some embodiments, the sliding structure 8 is fixed relative to the door frame 1. The sliding structure 8 can be configured as, but is not limited to, a cylindrical, semi-cylindrical, prismatic, or other shaped structure.

[0077] In some embodiments, a load-bearing structure 150 is provided on the door frame 1. The door panel 5 includes a door panel body 51 and an extension plate 52. The extension plate 52 is connected to the side of the door panel body 51 in the translational direction of the door panel 5 and is disposed on the transmission component 30 and the load-bearing structure 150. The door panel body 51 is provided with the sliding groove 7. Thus, the load-bearing structure 150 can support the door panel 5, improving the stability and reliability of the door panel 5's movement relative to the door frame 1.

[0078] The door panel 5 is configured with an L-shaped structure. In other words, the bottom of the door panel 5 near the door frame 1 has a clearance notch 502. In other words, the door panel body 51 and the extension plate 52 are connected to form the clearance notch 502. The clearance notch 502 of one of the door panels 5 is used to avoid the door panel body 51 of the other door panel 5, thereby improving the space occupied by the door panel 5 on the door frame 1 and making the overall structure of the automatic opening and closing device 300 more compact. When the two door panels 5 close the passage opening 1001, the door panel bodies 51 of the two door panels 5 are arranged along the translational direction of the door panels 5 and abut against each other, with the extension plate 52 of one door panel 5 located above the door panel body 51 of the other door panel 5.

[0079] In this embodiment, the supporting structure 150 is rotatably configured relative to the door frame 1. This rotatable configuration reduces energy consumption during door panel 5 movement, improves the stable operation of door panel 5, and reduces friction between door panel 5 and the supporting structure 150, thus lowering noise. For example, the supporting structure 150 can be configured as a bearing, thereby reducing friction and vibration between door panel 5 and door frame 1, lowering noise generated by the automatic switching device 300 during operation, and improving the stability and reliability of door panel 5's horizontal translation relative to door frame 1. Alternatively, the supporting structure 150 can be configured as a roller. Of course, in some embodiments, the supporting structure 150 is fixedly configured relative to door frame 1.

[0080] In some embodiments, the automatic switching device 300 further includes a first guide strip 160 and a second guide strip 170. The first guide strip 160 and the second guide strip 170 protrude from the side wall of the door frame 1 facing the door panel 5 and respectively abut against the two door panels 5, thereby reducing the contact area between the door panel 5 and the door frame 1, reducing friction, lowering noise, and improving the reliability and stability of the sliding of the door panel 5 relative to the door frame 1. Specifically, the first guide strip 160 and the second guide strip 170 are integrally formed with or detachably connected to the first crossbeam 110. The ends of the first guide strip 160 and the second guide strip 170 that abut against the door panel 5 are provided with rounded corner structures, thereby reducing the contact area between the door panel 5 and the door frame 1, reducing friction, and lowering noise.

[0081] Please refer to the following: Figure 6 and Figure 8 , Figure 8 yes Figure 6 This is an enlarged view of part I in the diagram. The supporting structure 150 is provided with a guide surface 1502, which abuts against the extension plate 52 and is configured as an arc surface, thereby reducing friction between the door panel 5 and the supporting structure 150, reducing noise, and improving the smoothness and stability of the door panel 5's movement relative to the supporting structure 150. Of course, in some embodiments, the guide surface 1502 can also be configured as a plane.

[0082] In this embodiment, the two door panels 5 are arranged along the thickness direction of the door panels 5. Therefore, the automatic switching device 300 has a simple and compact structure, occupying little space. Specifically, the side wall of the supporting structure 150 is provided with a partition strip 151, and the two door panels 5 are respectively located on both sides of the partition strip 151 along the thickness direction of the door panels 5. This avoids interference between the two door panels 5 when they move relative to the door frame 1, improving the reliability and smoothness of the movement of the two door panels 5 relative to the door frame 1, and preventing wear and noise problems caused by the two door panels 5 abutting against each other.

[0083] Please refer to the following: Figure 6 and Figure 9 , Figure 9 yes Figure 1 The diagram shows the front view of the automatic switch device 300 in the closed state. In some embodiments, the supporting structure 150 extends along the thickness direction of the door panel 5, and the supporting structure 150 has two limiting grooves 1501 in the thickness direction of the door panel 5, which are spaced apart. The two door panels 5 are respectively located within the two limiting grooves 1501. This avoids interference between the two door panels 5 when they move relative to the door frame 1, improves the reliability and smoothness of the movement of the two door panels 5 relative to the door frame 1, and avoids wear and noise problems caused by the two door panels 5 abutting against each other.

[0084] In some embodiments, the door panel 5 further includes a bending plate 53. The bending plate 53 is bent and connected to the side of the door panel body 51 near the extension plate 52 in the translational direction of the door panel 5. When the two door panels 5 close the passage opening 1001, the two bending plates 53 abut against each other. Thus, on the one hand, the overall structural strength of the door panel 5 is improved, reducing the risk of misalignment and jamming of the two door panels 5 during the closing process; on the other hand, the abutment of the two bending plates 53 avoids the problem of gaps between the two door panels trapping animals or keepers.

[0085] In some embodiments, the extension plate 52 has a positioning notch 501 on the side facing away from the door panel body 51. When the door panel 5 closes the passage opening 1001, the positioning notch 501 engages with the sliding structure 8. Thus, on the one hand, the sliding structure 8 can prevent excessive displacement of the door panel 5 relative to the door frame 1, improving the accuracy of the translational movement of the door panel 5 and the door frame 1, and preventing damage to the drive component 2; on the other hand, the sliding structure 8 can provide dual positioning for both closing and opening the door panel 5, reducing structural components, rationally arranging components, improving the overall compactness of the structure, and facilitating assembly.

[0086] Please refer to it again. Figure 4 , Figure 5 and Figure 10 , Figure 10 yes Figure 5 An enlarged view of part II. In some embodiments, all the door panels 5 and the door frame 1 are stacked in the thickness direction of the door panels 5; the automatic switching device 300 further includes a limiting structure 90, which is disposed on the door frame 1 and / or the door panels 5 and is used to limit the movement of the door panels 5 relative to the door frame 1 along the thickness direction of the door panels 5. Therefore, on the one hand, by setting all the door panels 5 and the door frame 1 to be stacked in the thickness direction of the door panel 5, the problem of existing door frames restricting the movement of the door panel along the thickness direction of the door panel by setting slots is solved, which increases the cleaning difficulty due to the slots being contaminated by animal feces and other impurities, and causes the door panel to be obstructed from translating relative to the door frame. This reduces the cleaning difficulty of the door frame 1 and the door panel 5, and improves the reliability and smoothness of the translation of the door panel 5 relative to the door frame 1. On the other hand, the limiting structure 90 can restrict the movement of the door panel 5 relative to the door frame 1 along the thickness direction of the door panel 5, thereby reducing the problem of the door panel 5 bending or even breaking relative to the door frame 1 under the impact force applied by the animal, and improving the stability and reliability of the translation of the door panel 5 relative to the door frame 1 in the horizontal X direction.

[0087] The limiting structure 90 includes a limiting head 901 and a limiting rod 902. One end of the limiting rod 902 is connected to the limiting head 901, and the other end is connected to the door frame 1 or the door panel 5. The limiting head 901 is used to stop against the door frame 1 or the door panel 5 to limit the movement of the door panel 5 relative to the door frame 1 along the thickness direction of the door panel 5. In this embodiment, the door panel 5 is spaced apart from the limiting rod of the limiting structure 90 and is located above the limiting rod. Thus, on the one hand, the friction between the door panel 5 and the limiting structure 90 is reduced, improving the smoothness and reliability of the translational movement of the door panel 5 relative to the door frame 1; on the other hand, it avoids the problem of the door panel 5 falling under gravity and injuring animals or keepers when the automatic control device is out of control, thus improving the safety of the automatic control device. Of course, in some embodiments, the door panel 5 abuts against the limiting rod of the limiting structure 90, so that the limiting structure 90 can support the door panel 5, improving the smoothness and reliability of the translational movement of the door panel 5 relative to the door frame 1.

[0088] For example, in this embodiment, the limiting structure 90 includes a first limiting body 9 and a second limiting body 10. The first limiting body 9 and the second limiting body 10 are located on different sides of the door frame 1 in the thickness direction of the door panel 5. The first limiting body 9 is installed on the door panel 5 and stops the door frame 1 in the thickness direction of the door panel 5. The second limiting body 10 is installed on the door frame 1 and stops the door panel 5 in the thickness direction of the door panel 5. The door panel 5 is defined between the first limiting body 9 and the second limiting body 10. Specifically, the first limiting body 9 and the second limiting body 10 each include a limiting head 901 and a limiting rod portion 902. The limiting head 901 of the first limiting body 9 stops the door frame 1 in the thickness direction of the door panel 5; the limiting head 901 of the second limiting body 10 stops the door panel 5 in the thickness direction of the door panel 5. Therefore, the synergistic effect of the first limiting body 9 and the second limiting body 10 can prevent the door panel 5 from swaying back and forth due to the pushing of animals, thereby improving the stability and accuracy of the door panel 5 during the opening and closing process, and enhancing the overall reliability and service life of the automatic opening and closing device 300. Specifically, the first limiting body 9 is located at the bottom of the door panel 5, and the second limiting body 10 is located on the second crossbeam 120 of the door frame 1.

[0089] Exemplarily, in this embodiment, the first limiting body 9 and the door panel 5, and the second limiting body 10 and the door frame 1, are independently arranged and fixedly connected. For example, both the first limiting body 9 and the second limiting body 10 are configured as rivet structures. Of course, in some embodiments, the first limiting body 9 and the door panel 5, and the second limiting body 10, are integrally formed with the door frame 1. The first limiting body 9 and the second limiting body 10 can both be provided on the door frame 1 or the door panel 5; this embodiment of the present invention does not impose specific limitations.

[0090] In some embodiments, the automatic switching device 300 further includes an energy storage component 12, which is electrically connected to the main control board 11 and the drive component 2. The protective housing 17 covers the outside of the energy storage component 12. The energy storage component 12 can supply power to electrical components such as the drive component 2 and the main control board, thereby simplifying the connection wiring of the automatic switching device 300, eliminating the need for external connection cables, and resulting in a simple and aesthetically pleasing structure. The energy storage component 12 may include a battery or a capacitor. The energy storage component 12 can be configured as a rechargeable structure or a non-rechargeable structure; this invention does not impose specific limitations.

[0091] In some embodiments, the automatic switching device 300 further includes a functional component 140. The functional component 140 is disposed on the main control board 11 and includes at least one of a display screen 13, buttons 14, a prompting structure 15, and a connection interface 16. This enables the automatic switching device 300 to offer a multi-functional experience and enriches the user experience. The display screen 13 can be configured as a touch screen or a non-touch screen to provide a visual display for the zookeeper. The buttons 14 include power buttons, parameter setting buttons, etc. For example, when the zookeeper operates the power button 14, the automatic switching device 300 automatically controls the opening or closing of the door panel 5, thereby reducing the zookeeper's workload of frequently manually opening and closing the door, and effectively avoiding management risks such as animals not being able to obtain food or water in time or escaping due to human negligence in forgetting to open or close the door panel 5, thus improving the efficiency and convenience of captive animal management. The prompting structure 15 may include, but is not limited to, speakers or lighting structures, to prompt the zookeeper to intervene in the automatic switching device 300 in a timely manner. The connection interface 16 may include, but is not limited to, a power interface, a communication interface, and a function expansion structure.

[0092] Please refer to the following: Figures 1 to 10 The working process of the automatic switching device provided in the first embodiment of this utility model is as follows.

[0093] Door opening process: During daily feeding time, the zookeeper presses button 14 on the main control board 11 and issues an opening command. Upon receiving the opening command, the main control board 11 sends a start signal to the drive component 2. The drive component 2 rotates in the forward direction, and its output shaft drives the main drive gear 3 to rotate, which in turn drives the driven gear 4 to rotate. The main drive gear 3 and the driven gear 4 mesh with the racks 6 on the two door panels 5, respectively, causing each door panel 5 to move along the direction of the sliding structure 8 and the sliding groove 7, and to translate in the straight line direction defined by the first limit body 9 and the second limit body 10, thus achieving synchronous opening of the two door panels. When the door panel is opened to the maximum position defined by the sliding structure 8, the load on the drive component increases, generating a large current. When the main control board 11 detects that the current exceeds the preset current value, it determines that the door panel has been opened to the correct position and immediately sends a stop signal to the drive component 2. The drive component 2 then stops operating, and the door opening action ends.

[0094] Closing Process: After feeding, the zookeeper presses button 14 on the main control board 11 again. The main control board 11 sends a reverse signal to the drive component 2, causing the drive component 2 to rotate in the opposite direction to the forward rotation. The main drive gear 3 and the driven gear 4 also rotate in the opposite direction, driving the door panel 5 to move in a straight line in the opposite direction, achieving synchronous closing of the two door panels. During the closing process, when a specific part on one of the door panels 5 contacts the positioning detector 18 on the door frame 1, the positioning detector 18 is triggered and sends a signal to the main control board 11. Upon receiving the signal, the main control board 11 immediately sends a stop command to the drive component 2, causing the drive component 2 to stop operating and the door panel to close accurately. If an animal is caught in the door panel 5 during the closing process, the drive component 2 needs to overcome additional resistance, causing a sudden increase in current. The current detection module 111 detects the abnormal signal of increased current and quickly transmits the abnormal signal to the main control board 11. Upon receiving an abnormal signal, the main control board 11 immediately stops the drive component 2 and issues a reverse command. The drive component 2 reverses its preset travel in the opposite direction to the forward rotation, causing the door panel 5 to move in the opposite direction, providing an opportunity for the animal to escape. Subsequently, the main control board 11 can automatically control the drive component 2 to continue executing the closing action according to the original closing command until the door panel is accurately closed in place.

[0095] Please refer to the following: Figure 1 , Figure 11 and Figure 12 , Figure 11 This is a partial structural diagram of the back of the automatic switch device 300 provided in the second embodiment of the present invention in the open state; Figure 12 yes Figure 11A partial structural diagram of the automatic switch device 300 in the open state is shown. In the second embodiment, the structure of the automatic switch device 300 is similar to that of the first embodiment, except that the transmission component 30 is configured as a belt drive, which includes a pulley 190, a belt 21, and a connecting block 22. The pulley 190 is connected to the drive component 2, the belt 21 is rotatably arranged around the outside of the pulley 190, one end of the connecting block 22 is fixedly connected to the belt 21, and the other end of the connecting block 22 is fixedly connected to the door panel 5. Therefore, because the belt 21 is elastic, it can absorb vibration and impact, reducing vibration and noise during transmission, thereby improving the stability and reliability of the translational movement of the door panel 5 relative to the door frame 1.

[0096] In this embodiment, the door panel 5 is configured as two panels, which are connected to the door frame 1 to form a double-door structure. Two connecting blocks 22 are provided, and each door panel 5 is fixedly connected to the belt 21 via the two connecting blocks 22. Therefore, firstly, the simultaneous opening of both door panels 5 provides a wider passageway 1001, facilitating the rapid evacuation of chickens or personnel; secondly, it shortens the distance each door panel 5 moves relative to the door frame 1, improving the overall compactness of the automatic opening and closing device 300.

[0097] For example, in this embodiment, the connecting block 22 is integrally formed with the door panel 5, thereby enhancing the connection strength and stability between the connecting block 22 and the door panel 5, reducing the risk of failure due to loose connection, and improving the overall performance and service life of the door panel 5. Of course, in some embodiments, the connecting block 22 and the door panel 5 are independently set and fixedly connected, thereby reducing the processing difficulty of the connecting block 22 and the door panel 5, and facilitating maintenance.

[0098] The pulley 190 includes a driving pulley 19 and a driven pulley 20. The driving pulley 19 is connected to the drive component 2. The belt 21 is rotatably disposed around the outside of the driving pulley 19 and the driven pulley 20. Thus, the drive component 2 can drive the driving pulley 19 to rotate, and the rotation of the driving pulley 19 drives the belt 21 and the driven pulley 20 to rotate. Of course, in some embodiments, the driven pulley 20 can be omitted. The number of both the driving pulley 19 and the driven pulley 20 is set to one. Of course, in some embodiments, there can be multiple driving pulleys 19 and driven pulleys 20. This embodiment of the present invention does not make a specific limitation.

[0099] It should be noted that the same structural elements in the automatic switching device 300 in the second embodiment as those in the automatic switching device 300 described in the first embodiment can be referred to in the automatic switching device 300 described in the first embodiment, and will not be repeated here. For example, the structure of the door panel 5 and the positional relationship between the door panel 5 and the door frame 1 described in the first embodiment are applicable to the second embodiment.

[0100] Please refer to the following: Figure 1 , Figure 11 and Figure 12 The working process of the automatic switching device 300 provided in the first embodiment of this utility model is as follows. The explanation will be based on the example of a cattle and sheep pen 100 used for raising cattle and sheep.

[0101] Opening Process: During daily grazing time, the keeper presses the opening button 14 on the main control board 11. Upon receiving the opening command, the main control board 11 sends a start signal to the drive component 2. The drive component 2 operates according to the start signal, and its output shaft drives the drive pulley 19 to rotate, which in turn drives the belt 21 to rotate. The left and right sections of the belt 21 are fixedly connected to the connecting blocks 22 on the two door panels 5, respectively, causing the door panels 5 to translate along the mating direction of the sliding structure 8 and the sliding groove 7, as well as the linear direction defined by the first limit body 9 and the second limit body 10, thus achieving synchronous opening of the two door panels. When the door panel is opened to the maximum position defined by the sliding structure 8, the load on the drive component 2 increases, generating a large current. When the current monitored by the main control board 11 in real time exceeds the preset current, it determines that the door panel has been opened to the correct position and immediately sends a stop signal to the drive component 2. The drive component 2 then stops operating, and the door opening action of the door panel ends. The cattle and sheep can easily pass through passageway 1001 of the pen to reach the pasture.

[0102] Closing Process: After grazing ends, the herder presses the closing button 14 on the main control board 11. The main control board 11 sends a reverse signal to the drive component 2, causing the drive component 2 to reverse. The drive pulley 19 and belt 21 also rotate in the opposite direction, driving the door panel 5 to move in a reverse linear motion, achieving synchronous closing of the two door panels. During the closing process, when a preset part on one of the door panels 5 contacts the positioning detector 18 on the door frame 1, the positioning detector 18 is triggered and sends a signal to the main control board 11. Upon receiving the signal, the main control board 11 immediately sends a stop command to the drive component 2, causing the drive component 2 to stop operating and the door panel to close accurately. If, during the closing process, the door panel 5 traps a cow or sheep, the drive component 2 needs to overcome additional resistance, causing a sudden increase in current. The current detection module 111 detects the increased current signal and quickly transmits the abnormal signal to the main control board 11. Upon receiving an abnormal signal, the main control board 11 immediately stops the drive component 2 and issues a reverse command. The drive component 2 reverses its preset travel in the opposite direction to the forward rotation, causing the door panel 5 to move in the opposite direction, providing an opportunity for the cattle and sheep to escape. Subsequently, the main control board 11 can automatically control the drive component 2 to continue executing the closing action according to the original closing command until the door panel is accurately closed in place, ensuring the safe enclosure is sealed.

[0103] The automatic switching device 300 provided in this embodiment of the present invention has the following advantages.

[0104] 1. The automatic opening and closing device 300 is highly automated and convenient. Specifically, this invention completely abandons the traditional manual sliding door operation mode, and constructs a complete automatic door opening and closing system with the help of the drive component 2, the main control board 11, and related circuits. The zookeeper only needs to operate the control buttons 14 or communication devices on the main control board 11 to easily open and close the door. This greatly reduces the workload of zookeepers who frequently manually open and close the door, and effectively avoids the management risks caused by human negligence in forgetting to open or close the door, such as animals not being able to obtain food or water in time or escaping, significantly improving the efficiency and convenience of captive animal management.

[0105] 2. Structural optimization and reliability improvement of the automatic opening and closing device 300. Compared with existing complex linkage-driven automatic doors, the transmission component 30 used in this device is simple and efficient, reducing a large number of moving parts. This not only reduces installation difficulty and enhances compatibility with various confined or specially laid-out enclosures, but also significantly reduces the failure rate caused by too many components. Simultaneously, the carefully designed limiting components, including the cooperation between the sliding structure 8 and the sliding groove 7, and the synergistic effect of the first limiting body 9 and the second limiting body 10, ensure the stability and accuracy of the door panel 5 during opening and closing, significantly improving the overall reliability and service life of the device.

[0106] 3. The automatic switching device 300 has excellent safety protection performance. The position detector 18 installed on the door frame 1 can accurately control the closing position of the door panel 5, preventing damage caused by excessive closing of the door panel 5. More importantly, the innovative anti-pinch function based on the current detection module 111 provides reliable safety protection for captive animals. During the closing process, if the door panel 5 pinches an animal, the current detection module 111 can quickly detect the abnormal increase in current of the drive component 2 and accurately transmit the signal to the main control board 11. The main control board 11 then controls the drive component 2 to stop operating and reverse, creating an opportunity for the animal to escape, and then automatically continues to complete the closing action. This function greatly reduces the risk of animals being pinched and effectively protects the safety and welfare of animals.

[0107] 4. The automatic switching device 300 offers flexible connection methods and ease of maintenance. Specifically, for the connection between the rack 6 / connecting block 22 and the door panel 5, two design options are provided: one-piece molding and separate screw fixing. The one-piece molding design enhances the connection strength and stability between the rack 6 / connecting block 22 and the door panel 5, reducing potential failures and making it suitable for scenarios with high requirements for overall door performance. The separate design facilitates the installation and replacement of the rack 6 / connecting block 22. When the rack 6 / connecting block 22 is worn or damaged, it can be repaired quickly and conveniently, reducing maintenance costs and difficulty, and meeting the diverse needs and usage scenarios of different keepers.

[0108] 5. The automatic switch device 300 features user-friendly operation and enhanced monitoring capabilities. Specifically, the main control board 11 integrates a display screen 13, control buttons 14, a prompting structure 15, and a connection interface 16, providing operators with a user-friendly operation and monitoring experience. The display screen 13 shows the device's operating status and key parameters in real time, allowing operators to easily monitor the situation. The control buttons 14 are easy to operate, enabling precise control of the door opening and closing. The prompting structure 15 provides timely audible alerts during door opening and closing processes and in case of abnormalities, reminding operators to pay attention. The connection interface 16 meets the connection requirements of the automatic switch device 300 with external devices, facilitating data transmission and charging operations, further enhancing the practicality and functionality of the automatic switch device 300.
