Description

Technical Field

[0001] This utility model relates to the field of controller technology, and in particular to a controller for emergency mode switching. Background Technology

[0002] Controllers with emergency mode switching are critical safety devices widely used in industrial machinery, automated production lines, and power systems. Their core design is to immediately cut off the power supply to the equipment or trigger a safety circuit by pressing a prominent emergency stop button in the event of a sudden hazard, achieving rapid shutdown and effectively protecting personnel safety and equipment integrity. These controllers typically have a mechanical self-locking function, requiring manual reset to resume operation and preventing misoperation. The housing is made of impact-resistant materials, with a protection level of IP65 or higher, adapting to harsh environments. As a key node in the safety chain, it is an indispensable component of modern safe production.

[0003] In existing technologies, the removal of the back cover of an emergency mode switching controller is often cumbersome and inefficient. Traditional designs often use multiple screws for fixing, requiring special tools to unscrew them one by one during disassembly. This is not only time-consuming and laborious, but also leads to maintenance difficulties due to stripped or lost screws. Some products use a snap-fit ​​structure, but these are often too tight or aged to be opened by hand, sometimes requiring a pry bar and posing a risk of damaging the casing. In addition, the sealing structure between the back cover and the main body is prone to deformation and failure after repeated disassembly and reassembly, affecting the protective performance. More complex integrated controllers require disconnecting the internal cables before the back cover can be completely separated, further increasing the difficulty of maintenance. These problems not only prolong equipment maintenance time, but also lead to secondary malfunctions due to improper operation. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an emergency mode switching controller.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: an emergency mode switching controller, including a controller upper cover, a controller lower cover, and an emergency stop button. The controller lower cover is located at the bottom of the controller upper cover, and the emergency stop button is located on the surface of the controller upper cover. Each bottom corner of the controller upper cover has a latching groove. The inner wall of each latching groove has two first latching sliding grooves and two second latching sliding grooves. The inner wall of each latching groove has a first limiting shaft and a second limiting shaft. First sliding blocks are fixed to both ends of the first limiting shaft. The first sliding blocks slide on the inner wall of the first latching sliding groove. First springs are fixed to both sides of each first sliding block, and the other end of each first spring is fixed to the inner wall of the first latching sliding groove. Second sliding blocks are fixed to both ends of each second limiting shaft. The second sliding blocks slide on the inner wall of the second latching sliding groove. Second springs are fixed to both ends of each second sliding block, and one end of each second spring is fixed to the inner wall of the second latching sliding groove. A latching seat is fixed to each top corner of the controller lower cover.

[0006] Preferably, the controller's upper cover has sliding limiting grooves on both sides, and the controller's lower cover has a fixed base on its back. Two limiting blocks are fixed to the inner wall of the fixed base, and the limiting blocks slide against the inner wall of the sliding limiting grooves. A limiting base plate is fixed to one side of the fixed base. In the prior art, emergency mode switching controllers have significant limitations in their installation methods. While fixed controllers are highly stable, they cannot be moved flexibly, requiring operators to quickly move to a fixed position to trigger the switch in an emergency, delaying response time. Handheld controllers, while portable, lack reliable fixing methods, making them prone to slipping or accidental contact in industrial environments, affecting operational safety. Furthermore, neither method typically allows for quick switching between usage scenarios. Fixed controllers are difficult to temporarily disassemble for handheld use, and handheld controllers lack convenient mounting brackets, resulting in limited application scenarios. This either-or design restricts the controller's adaptability in complex industrial environments, failing to meet the dual requirements of rapid response and stable operation. To address these issues, this utility model adopts a fixed handheld design. The switching structure allows for seamless switching between fixed installation and portable use. When the controller needs to be fixed to a machine, a mounting base is fixed to the machine surface. The sliding limit slots on both sides of the controller's top cover are inserted into the limit blocks, allowing it to slide to the bottom. The limit base plate ensures stability when installed on the machine. When handheld use is required, the controller can be pulled out, achieving a seamless switch between fixed installation and portable use. This significantly improves emergency response efficiency in industrial scenarios. Through the switchable fixed and handheld structure, the controller can be firmly installed on the equipment surface or detached with one click to switch to handheld mode. This ensures that operators can quickly trigger an emergency stop in both mobile and fixed scenarios. This flexible dual-mode design retains the stability of fixed control while also providing the mobility of handheld devices. Emergency operations are no longer limited by the installation location, significantly improving the safety and convenience of human-machine collaboration.

[0007] Preferably, the controller's upper cover surface has an anti-accidental touch groove, and the emergency stop button is located inside the anti-accidental touch groove. In the prior art, the emergency stop button of the emergency mode switching controller is usually arranged side by side with other operation buttons, which poses a significant risk of accidental touch. Due to the lack of isolation, operators may accidentally trigger the emergency brake due to hand slippage or visual misjudgment during rapid operation, causing abnormal equipment shutdown. Although some designs use red markings, they are still difficult to quickly identify in low light or emergency situations. More seriously, some compact controllers place the emergency stop button adjacent to frequently used function keys, further increasing the probability of accidental touch. This design defect can not only cause production interruptions but also create safety hazards in critical processes. To address these issues, this utility model adopts a recessed design for the emergency stop button, placing it inside the anti-accidental touch groove, effectively preventing accidental touch, significantly reducing the risk of accidental touch, reducing equipment shutdowns and production interruptions caused by accidental triggering of emergency brakes, and improving operational safety, especially in low light or emergency situations, ensuring that operators can quickly and accurately identify and operate the emergency stop button, thereby ensuring the stability of equipment operation and the safety of operators.

[0008] Preferably, the top of the controller cover has two support seats fixedly attached, one side of which is rotatably connected to an isolation plate, and the other side of the controller cover is fixed with a locking buckle. This significantly improves operational safety. A horizontally rotatable isolation plate is added above the emergency stop button. Normally, it covers the button to form a physical barrier. In an emergency, the isolation plate must be pushed open before the button can be accessed. The isolation plate is made of semi-transparent orange engineering plastic, which maintains the visibility of the button while enhancing its recognizability through both color and tactile warnings.

[0009] Preferably, the isolation plate has a slanted groove on one side. This makes it easier for the isolation plate to disengage from the locking buckle when opened, improving work efficiency while ensuring the rapid operation of the emergency stop button.

[0010] Preferably, both sides of the controller's upper and lower covers are curved. The curved design on both sides conforms to an ergonomic contour, significantly improving the comfort and stability of handheld operation. It perfectly fits the natural grip curve of the human hand, ensuring even force distribution when holding with one hand and reducing fatigue during prolonged operation.

[0011] Preferably, the engaging parts of the buckle seats are all arc-shaped. This significantly improves the ease of installation and structural reliability. The radius of curvature of the arc-shaped engaging surface is precisely calculated, enabling the upper and lower covers to achieve a progressive engagement when closed.

[0012] Beneficial effects:

[0013] 1. In existing technologies, the removal of the back cover of an emergency mode switching controller is typically cumbersome and inefficient. Traditional designs often use multiple screws for fixing, requiring specialized tools to unscrew them one by one. This is not only time-consuming and laborious, but also leads to maintenance difficulties due to stripped or lost screws. Some products use a snap-fit ​​structure, but these are often too tight or worn to be opened by hand, sometimes requiring a pry bar and posing a risk of damaging the casing. Furthermore, the sealing structure between the back cover and the main body is prone to deformation and failure after repeated disassembly and reassembly, affecting protective performance. More complex integrated controllers require disconnecting internal cables before the back cover can be completely separated. These issues not only prolong equipment maintenance time but also lead to secondary malfunctions due to improper operation, but also increase maintenance difficulty. To address these problems, this utility model adopts a removable rear cover structure, which significantly improves the convenience and maintenance efficiency of controller rear cover removal. The removable design allows for tool-free operation, greatly shortening disassembly and assembly time. These improvements not only reduce maintenance difficulty and the risk of misoperation but also reduce component damage caused by disassembly, extending equipment life. At the same time, it meets the dual requirements of efficient maintenance and safety protection in industrial environments, ultimately achieving the effect of minimizing equipment downtime and optimizing operation and maintenance costs.

[0014] 2. Existing emergency mode switching controllers have significant limitations in installation methods. While fixed controllers offer high stability, they cannot be moved flexibly, requiring operators to quickly move to a fixed location to trigger the switch in emergencies, delaying response time. Handheld controllers, while portable, lack reliable mounting methods, making them prone to slipping or accidental contact in industrial environments, affecting operational safety. Furthermore, neither method typically allows for rapid switching between usage scenarios; fixed controllers are difficult to temporarily disassemble for handheld use, and handheld controllers lack convenient mounting brackets, resulting in limited application scenarios. This either-or design restricts the controller's versatility in complex scenarios. The adaptability to complex industrial environments makes it difficult to simultaneously meet the dual requirements of rapid response and stable operation. To address this issue, this utility model adopts a switchable fixed-mount handheld structure, achieving seamless switching between fixed installation and portable use. This significantly improves the emergency response efficiency in industrial scenarios. Through the switchable fixed-mount handheld structure, the controller can be firmly installed on the equipment surface and can also be detached with a single button to switch to handheld mode. This ensures that operators can quickly trigger an emergency stop in both mobile and fixed scenarios. This flexible dual-mode design retains the stability of fixed control while also possessing the mobility of handheld devices, so that emergency operations are no longer limited by the installation location, significantly improving the safety and convenience of human-machine collaboration.

[0015] 3. In existing technologies, the emergency stop button of the emergency mode switching controller is usually arranged side by side with other operation buttons, posing a significant risk of accidental activation. Due to the lack of isolation, operators may accidentally trigger the emergency brake due to hand slippage or visual misjudgment during rapid operation, leading to abnormal equipment shutdown. Although some designs use red markings, they are still difficult to quickly identify in low light or emergency situations. More seriously, some compact controllers place the emergency stop button adjacent to frequently used function keys, further increasing the probability of accidental activation. This design flaw can not only cause production interruptions but also pose safety hazards in critical processes. To address these issues, this utility model adopts a recessed design for the emergency stop button, significantly reducing the risk of accidental activation, minimizing equipment shutdowns and production interruptions caused by accidental emergency braking, and improving operational safety. Especially in low light or emergency situations, it ensures that operators can quickly and accurately identify and operate the emergency stop button, thereby guaranteeing the stability of equipment operation and the safety of operators.

[0024] To make the technical means, creative features, and achieved objectives and effects of this utility model easier to understand, the present utility model is further described below with reference to specific embodiments and accompanying drawings. However, the following embodiments are merely preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described in the implementation plan without creative effort are all within the protection scope of this utility model.

[0025] The specific embodiments of this utility model are described below with reference to the accompanying drawings. Specific implementation examples:

[0027] Reference Figure 1-6An emergency mode switching controller includes an upper controller cover 1, a lower controller cover 101, and an emergency stop button 102. The lower controller cover 101 is located at the bottom of the upper controller cover 1, and the emergency stop button 102 is located on the surface of the upper controller cover 1. Each corner of the bottom of the upper controller cover 1 has a latching groove 103. The inner wall of each latching groove 103 has two first latching sliding grooves 104 and two second latching sliding grooves 105. The inner wall of each latching groove 103 has a first limiting shaft 106 and a second limiting shaft 107. First sliding blocks 108 are fixed to both ends of the first limiting shaft 106. The first sliding block 108 slides on the inner wall of the first snap-fit ​​sliding groove 104. The first spring 109 is fixed on both sides of the first sliding block 108. The other end of the first spring 109 is fixed to the inner wall of the first snap-fit ​​sliding groove 104. The second sliding block 110 is fixed on both ends of the second limiting shaft 107. The second sliding block 110 slides on the inner wall of the second snap-fit ​​sliding groove 105. The second spring 111 is fixed on both ends of the second sliding block 110. The two ends of the second spring 111 are fixed to the inner wall of the second snap-fit ​​sliding groove 105. The snap-fit ​​seat 112 is fixed at the top corner of the controller lower cover 101. In existing technologies, disassembling the back cover of an emergency mode switching controller is typically cumbersome and inefficient. Traditional designs often use multiple screws for fixing, requiring specialized tools to unscrew them one by one, which is not only time-consuming and laborious but also leads to maintenance difficulties due to stripped or lost screws. Some products use a snap-fit ​​structure, but these are often too tight or worn to be opened by hand, sometimes requiring a pry bar and posing a risk of damaging the casing. Furthermore, the sealing structure between the back cover and the main body is prone to deformation and failure after repeated disassembly and reassembly, affecting protective performance. More complex integrated controllers require disconnecting internal cables before the back cover can be completely separated, further increasing maintenance difficulty. These problems not only prolong equipment maintenance time... In addition, improper operation may lead to secondary malfunctions. To address this issue, this utility model adopts a removable rear cover structure. When the rear cover needs to be removed, simply pull the lower cover 101 of the controller, causing the lower cover 101 of the controller to drive the buckle seat 112. Under the action of force, the first limiting shaft 106 and the second limiting shaft 107 drive the first sliding block 108 and the first spring 109 to slide on the inner wall of the first buckle sliding groove 104 and the second buckle sliding groove 105, so that the buckle seat 112 is released from the limiting restraint of the first limiting shaft 106 and the second limiting shaft 107. After disassembly, the first spring 109 and the second spring 111 return to the original position for easy installation.

[0028] The controller upper cover 1 has sliding limit grooves 2 on both sides, and the controller lower cover 101 has a fixed seat 201 on the back. Two limit blocks 202 are fixed on the inner wall of the fixed seat 201. The limit blocks 202 slide on the inner wall of the sliding limit groove 2. A limit base plate 203 is fixed on one side of the fixed seat 201. In existing technologies, emergency mode switching controllers have significant limitations in installation methods. While fixed controllers offer high stability, they cannot be moved flexibly, requiring operators to quickly move to a fixed position to trigger the switch in emergencies, thus delaying response time. Handheld controllers, while portable, lack reliable fixing methods and are prone to slipping or accidental contact in industrial environments, affecting operational safety. Furthermore, neither method allows for quick switching between usage scenarios. Fixed controllers are difficult to temporarily disassemble for handheld use, while handheld controllers lack convenient mounting brackets, resulting in limited application scenarios. This either-or design restricts the controller's adaptability in complex industrial environments, failing to meet the dual requirements of rapid response and stable operation. To address these issues, this invention adopts a fixed handheld switching structure. When fixed for use on a machine, a mounting base 201 is fixed to the machine surface. The sliding limit grooves 2 on both sides of the controller's top cover 1 are inserted into the limit blocks 202, allowing it to slide to the bottom. The limit base plate 203 ensures stability when mounted on the machine. When handheld use is required, the controller can be pulled out.

[0029] The controller cover 1 has an anti-accidental touch groove 3 on its surface, and the emergency stop button 102 is located inside the anti-accidental touch groove 3. In the prior art, the emergency stop button of the emergency mode switching controller is usually arranged side by side with other operation buttons, which poses a significant risk of accidental touch. Due to the lack of isolation, operators may accidentally trigger the emergency brake due to hand slippage or visual misjudgment during rapid operation, causing abnormal equipment shutdown. Although some designs use red markings, they are still difficult to quickly identify in low light or emergency situations. More seriously, some compact controllers place the emergency stop button next to frequently used function keys, further increasing the probability of accidental touch. This design defect can not only cause production interruptions, but may even create safety hazards in critical processes. To address these issues, this utility model adopts a recessed design for the emergency stop button, placing it inside the anti-accidental touch groove 3 to effectively prevent accidental touch.

[0030] Two support bases 4 are fixed to the top of the controller cover 1. An isolation plate 401 is rotatably connected to one side of the support base 4, and a locking buckle 402 is fixed to one side of the controller cover 1, which significantly improves operational safety. A horizontally rotatable isolation plate is added above the emergency stop button. Normally, it covers the button to form a physical barrier. In an emergency, the isolation plate must be pushed open before the button can be accessed. The isolation plate is made of semi-transparent orange engineering plastic, which maintains the visibility of the button and enhances the identification through dual warnings of color and touch. A slanted groove 5 is opened on one side of the isolation plate 401, making it easier to pry open and disengage from the locking buckle when the isolation plate 401 is opened. The 402 locking mechanism improves work efficiency while ensuring rapid operation of the emergency stop button. Both sides of the controller upper cover 1 and controller lower cover 101 are curved, with an ergonomic curved contour that significantly improves the comfort and stability of handheld operation. It can perfectly fit the natural grip curve of the human hand, so that the force is evenly distributed when holding with one hand, and it is not easy to get tired during long-term operation. The locking parts of the buckle seat 112 are all curved, which significantly improves the convenience of installation and structural reliability. The radius of curvature of the curved locking surface has been precisely calculated so that the upper and lower covers can achieve progressive engagement when closed.

[0031] The working principle of this utility model is as follows: When the back cover needs to be removed, simply pull the lower cover 101 of the controller with force, so that the lower cover 101 of the controller drives the buckle seat 112. Under the action of force, the first limiting shaft 106 and the second limiting shaft 107 drive the first sliding block 108 and the first spring 109 to slide on the inner wall of the first buckle sliding groove 104 and the second buckle sliding groove 105, so that the buckle seat 112 is released from the limiting restraint of the first limiting shaft 106 and the second limiting shaft 107. After disassembly, the first spring 109 and the second spring 111 return to the original position for easy installation. When it needs to be fixed on the machine, the machine surface will be fixed with a fixing seat 201. Insert the sliding limiting grooves 2 on both sides of the upper cover 1 of the controller into the limiting block 202 and let it slide to the bottom. Under the action of the limiting base plate 203, the stability of the machine can be guaranteed. When it needs to be used by hand, the controller can be pulled out. The emergency stop button is set in the anti-accidental touch groove 3 to effectively prevent accidental touch.

[0032] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.
