Abstract
Description
Technical Field
[0001] This application relates to the field of power line opening and closing technology, and in particular to an electric opening and closing device. Background Technology
[0002] With the development of power transmission technology, generator truck technology has emerged. As a temporary power supply device, the generator truck can disconnect the power at the maintenance location through secondary grid connection operation when the power grid needs maintenance, ensuring that the user's power supply is not interrupted, so as to carry out safe maintenance, and switch back to the original power grid after the maintenance is completed.
[0003] In related technologies, when power grid maintenance is required, the generator truck must first be physically connected to the downstream of the location to be maintained. The upstream of the power grid is connected to the downstream of the location to be maintained via a low-voltage switch. After the generator truck and the power grid are synchronized once, the generator truck is connected to the power grid and the low-voltage switch is opened, achieving seamless connection of the generator truck. This ensures normal power supply to users while de-energizing the location to be maintained for maintenance. After maintenance, the generator truck and the power grid need to be synchronized a second time. The existing method is to connect a quasi-synchronization platform to the power grid via a bypass cable and bypass switch, enabling the generator truck and the power grid to synchronize a second time. After the generator truck and the upstream power supply are synchronized, the low-voltage main switch is closed, and the cable connection between the power grid and the generator truck is disconnected, restoring the original power grid supply. The above-mentioned method of controlling the low-voltage switch usually involves manually pulling the operating handle to open and close the switch.
[0004] However, the aforementioned method of manually operating the switch to open or close it poses a certain risk because the operator needs to directly contact the operating handle. Currently, a method using a remote control device to operate the switch handle has emerged. However, when the device moves the operating handle, the operator is too far away to visually determine whether the handle has moved to the correct position, thus making it impossible to confirm whether the switch has closed or opened. The operator usually needs to go to the location of the handle to confirm, resulting in low automation and inconvenience in practical use. Furthermore, existing switching devices are typically fixed structures, making them incompatible with different types of operating handles. In practice, different switching devices need to be carried for matching, further complicating the user experience. Utility Model Content
[0005] Therefore, it is necessary to provide an electric opening and closing device with a higher degree of automation and better adaptability to address the problems of low automation and poor adaptability of the aforementioned opening and closing equipment.
[0006] An electric opening and closing device, comprising:
[0007] Mounting rack;
[0008] The drive mechanism is connected to the mounting bracket;
[0009] A transmission component is connected to the drive mechanism, and the drive mechanism drives the transmission component to move.
[0010] An active mechanism is connected to the transmission assembly, and the transmission assembly moves to drive the active mechanism to move in a predetermined direction; the active mechanism is used to drive the operating handle to the open or closed position.
[0011] Multiple detection components are spaced apart along the predetermined direction and are used to detect the position of the active mechanism;
[0012] A control component is electrically connected to the detection component. The control component is used to control the movement of the active mechanism according to the position of the active mechanism detected by the detection component. When the active mechanism drives the operating handle to the open or closed position, the control component controls the active mechanism to stop moving.
[0013] In some embodiments, the movable mechanism includes a movable block connected to the transmission assembly, the movable block having a snap-fit groove, and the operating handle snapping into the snap-fit groove, so that the operating handle moves with the movable block.
[0014] In some embodiments, the detection assembly includes a mounting block, an elastic plate, and a pressure sensor. The mounting block is connected to the mounting frame. One end of the elastic plate is connected to the side of the mounting block facing the movable block. The elastic plate is inclined relative to the mounting block, and the other end of the elastic plate is away from the mounting block. The pressure sensor is located on the side of the mounting block corresponding to the other end of the elastic plate.
[0015] The movable mechanism further includes an abutment block connected to the movable block and abutting against the elastic plate. When the abutment block moves from the end of the elastic plate connected to the mounting block to the end of the elastic plate away from the mounting block, the abutment block presses the end of the elastic plate away from the mounting block closer to the mounting block.
[0016] In some embodiments, the transmission assembly includes a plurality of gears and a rotating shaft, the rotating shaft being connected to the drive mechanism, and the gears being connected to the rotating shaft;
[0017] The movable mechanism also includes a rack, which is connected to the movable block. The length direction of the rack is set along the predetermined direction and cooperates with the gear.
[0018] In some embodiments, the electric opening and closing device further includes a clutch mechanism, including one of the following:
[0019] The drive mechanism is connected to the transmission assembly through the clutch mechanism. The clutch mechanism is used to drive the transmission assembly to move relative to the drive mechanism, so that the drive mechanism and the transmission assembly are connected or separated. When the transmission assembly and the drive mechanism are connected, the drive mechanism drives the movable mechanism to move.
[0020] A portion of the transmission assembly is connected to another portion of the transmission assembly via the clutch mechanism. The clutch mechanism is used to drive the portion of the transmission assembly to move relative to the other portion of the transmission assembly, so that the structures of the transmission assembly are connected or separated. When the structures of the transmission assembly are connected, the drive mechanism drives the movable mechanism to move.
[0021] The movable mechanism is connected to the transmission assembly via the clutch mechanism. The clutch mechanism is used to drive the transmission assembly to move relative to the movable mechanism, so that the movable mechanism and the transmission assembly are connected or separated. When the transmission assembly and the movable mechanism are connected, the drive mechanism drives the movable mechanism to move.
[0022] In some embodiments, the clutch mechanism includes an electromagnetic clutch.
[0023] In some embodiments, the mounting bracket is provided with a plurality of limiting members, which are configured to correspond to the movable mechanism and are used to limit the range of motion of the movable mechanism.
[0024] In some embodiments, the limiting member includes two limiting plates, both of which are connected to the mounting bracket. The two limiting plates are respectively located on both sides of the movable mechanism in a predetermined direction, and the limiting plates abut against the movable mechanism.
[0025] In some embodiments, the mounting bracket is further provided with a guide rail, the length direction of which is set along the predetermined direction; the movable mechanism is slidably connected to the guide rail and slides along the length direction of the guide rail.
[0026] In some embodiments, the drive mechanism includes a motor, the output shaft of which is connected to the transmission assembly.
[0027] The aforementioned electric circuit breaker device uses a drive mechanism to drive a transmission component, which in turn drives a movable mechanism. This, in turn, moves the operating handle connected to the movable mechanism in a predetermined direction, allowing the operating handle to move between the open and closed positions, thus enabling remote control of the operating handle's opening and closing. This electric circuit breaker device is installed according to the operating handle's range of motion. Since the movable mechanism drives the operating handle, when the operating handle moves to the closed or open position, the corresponding position of the operating handle will be reached. Therefore, by obtaining the current position of the movable mechanism through a detection component, it is possible to determine whether the operating handle has moved to the correct position without operator intervention. When the detection component detects that the movable mechanism and operating handle have reached the correct position, the control component can stop the movable mechanism's movement, preventing excessive movement and achieving a high degree of automation. Furthermore, different operating handles require different travel distances for opening and closing. The control component can adjust the travel distance of the movable mechanism by controlling the drive mechanism, thereby adapting to different operating handles and setting different open and closed positions, ensuring the operating handle stops after reaching the correct position. Therefore, the electric circuit breaker device of this application has high adaptability. Attached Figure Description

Detailed Implementation
[0034] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.
[0035] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.
[0036] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.
[0037] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.
[0038] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.
[0039] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.
[0040] See Figure 1 , Figure 2 and Figure 3 , Figure 1 A schematic diagram of the overall structure of the electric opening and closing device in one embodiment of this application is shown; Figure 2 This diagram illustrates the disassembled structure of the drive mechanism 200, transmission assembly 300, and movable mechanism 400 in an electric opening and closing device according to an embodiment of this application. It should be noted that this is for ease of demonstration of the internal structure. Figure 2 The mounting bracket 100 and other structures were not shown in the image. Figure 3This diagram shows an overall structural schematic of the electric opening and closing device from another angle in one embodiment of the present application. One embodiment of the present application provides an electric opening and closing device, which includes a mounting frame 100, a drive mechanism 200, a transmission assembly 300, a moving mechanism 400, a detection assembly 500, and a control assembly (not shown in the figure). The drive mechanism 200 is connected to the mounting bracket 100; the transmission assembly 300 is connected to the drive mechanism 200, and the drive mechanism 200 drives the transmission assembly 300 to move; the movable mechanism 400 is connected to the transmission assembly 300, and the transmission assembly 300 moves to drive the movable mechanism 400 to move in a predetermined direction; the movable mechanism 400 is used to drive the operating handle (not shown in the figure) to the open or closed position; multiple detection components 500 are provided, and the multiple detection components 500 are spaced apart in a predetermined direction and are used to detect the position of the movable mechanism 400; the control component is electrically connected to the detection components 500, and the control component is used to control the movement of the movable mechanism 400 according to the position of the movable mechanism 400 detected by the detection components 500. When the movable mechanism 400 drives the operating handle to the open or closed position, the control component controls the movable mechanism 400 to stop moving.
[0041] See Figure 1 , Figure 2 and Figure 3 The drive mechanism 200 is fixed on the mounting bracket 100, which can be placed on a supporting surface such as the ground for easy placement and use.
[0042] The transmission assembly 300 can be a gear set, pulley and belt combination, etc. The transmission assembly 300 is connected to the drive mechanism 200, so that the drive mechanism 200 drives the transmission assembly 300 to run. The movable mechanism 400 is connected to the transmission assembly 300. When the transmission assembly 300 runs, it drives the movable mechanism 400 to move in the vertical direction. The movement direction of the movable mechanism 400 can be adjusted by adjusting the running direction of the drive mechanism 200.
[0043] It should be noted here that since the opening and closing operation handle is usually moved up and down to perform the opening and closing operation, the movable mechanism 400 moves in the vertical direction corresponding to the operation handle, that is, the predetermined direction is determined as the vertical direction according to the movement direction of the operation handle.
[0044] Multiple detection components 500 are spaced apart on the mounting frame 100 along the running path of the movable mechanism 400. During movement, the movable mechanism 400 can contact the detection components 500 to obtain its current position and send corresponding signals to the control component. The movable mechanism 400 moves between two detection components 500, the positions of which are determined by the closing and opening positions of the operating handle. When the movable mechanism 400 contacts one detection component 500, the operating handle is in the closing position; when it contacts the other detection component 500, the operating handle is in the opening position. When a detection component 500 detects that the movable mechanism 400 has moved to a pre-set detection component 500, it determines that the operating handle has reached its position and controls the movable mechanism 400 to stop moving via the control component.
[0045] During installation, the operating handle is connected to the movable mechanism 400. For ease of understanding, assume that moving the operating handle downwards opens the circuit and moving it upwards closes the circuit. Initially, the operating handle is in the open position, meaning the movable mechanism 400 is in contact with the lower detection component 500. When closing is required, the drive mechanism 200, through the transmission component 300, moves the movable mechanism 400 upwards, thereby driving the operating handle upwards until the movable mechanism 400 contacts the upper detection component 500. The control component then stops the movable mechanism 400, completing the closing operation. Similarly, when opening is required, the movable mechanism 400 drives the operating handle downwards until it contacts the lower detection component 500, completing the opening operation. When adapting to different operating handles, the contact position between the movable mechanism 400 and the detection component 500 can be adjusted by adjusting the distance between the multiple detection components 500 or by setting contact points with the detection components 500 at different positions on the movable mechanism 400, thus adapting to different operating handles.
[0046] It should be noted that, for example, if an operating handle needs to rotate 45° to move from the open position to the closed position, the distance between multiple detection components 500 can be adjusted so that the movable mechanism 400 moves from a position contacting the lower detection component 500 to a position contacting the upper detection component 500, precisely driving the operating handle to rotate 45°. The movable mechanism 400 and detection components 500 are set to correspond to the open and close positions of the operating handle. When the opening and closing rotation angle of the operating handle to be adapted is 60°, the upper detection component 500 can be moved away from the lower detection component 500, so that the movable mechanism 400 drives the operating handle to rotate exactly 60°, thereby adapting to different operating handles. The above method is only one embodiment for ease of understanding and is not the only embodiment, nor does it limit the specific implementation.
[0047] The above-described configuration detects whether the operating handle has moved into position, reducing manual operation. The detection result stops the moving mechanism 400, preventing damage caused by excessive handle movement. This effectively improves automation and simplifies the opening and closing operation. Furthermore, this electric opening and closing device is compatible with different operating handles, making it even more convenient to use.
[0048] Furthermore, it should be noted that the control component includes a signal receiving module or signal receiver for receiving opening and closing control signals. This allows the control of the drive mechanism 200 based on the received opening and closing signals, enabling remote control of the operating handle for opening and closing operations. Additionally, the control component includes a signal transmitting module or signal transmitting device for transmitting the operating handle status detected by the detection component 500. Users receiving the signal from the signal transmitting module or device can remotely ascertain the current status of the operating handle. The control component can also receive synchronization signals between the power grid and the generator. If the power grid and the generator have not synchronized, the operating handle will not be driven to perform opening and closing operations. If the power grid and the generator have synchronized, the operating handle will be driven to perform the corresponding opening and closing operations upon receiving the opening and closing signal.
[0049] In some embodiments, the movable mechanism 400 includes a movable block 410 connected to the transmission assembly 300. The movable block 410 has a snap-fit groove 411, and the operating handle is snapped into the snap-fit groove 411, so that the operating handle moves with the movable block 410.
[0050] See Figure 1 A locking groove 411 is formed on the side of the movable block 410 facing away from the transmission assembly 300, so that the operating handle can be inserted into the locking groove 411. It should be noted that the locking groove 411 can be a rectangular groove, and the inner sidewalls of the locking groove 411 at the top and bottom can abut against the operating handle, thereby driving the operating handle to move up and down, thus realizing the opening and closing operation. With the above configuration, the opening and closing operation can be realized, and the design is simple to manufacture and has good stability.
[0051] In some embodiments, the detection component 500 includes a mounting block 510, an elastic plate 520, and a pressure sensor (not shown). The mounting block 510 is connected to the mounting bracket 100. One end of the elastic plate 520 is connected to the side of the mounting block 510 facing the movable block 410. The elastic plate 520 is inclined relative to the mounting block 510, and the other end of the elastic plate 520 is away from the mounting block 510. The pressure sensor is located on the side of the mounting block 510 corresponding to the other end of the elastic plate 520. The movable mechanism 400 also includes an abutment block 420, which is connected to the movable block 410 and abuts against the elastic plate 520. When the abutment block 420 moves from the end of the elastic plate 520 connected to the mounting block 510 to the end of the elastic plate 520 away from the mounting block 510, the abutment block 420 presses the end of the elastic plate 520 away from the mounting block 510 closer to the mounting block 510.
[0052] See Figure 3 , Figure 4 and Figure 5 The system comprises four detection components 500, with two components 500 positioned at the top and the other two at the bottom, each with a smaller gap between them. In the two upper detection components 500, the upper end of the elastic plate 520 is connected to the upper sidewall of the mounting block 510. In the two lower detection components 500, the lower end of the elastic plate 520 is connected to the lower sidewall of the mounting block 510, forming the structure shown in the figure, facilitating contact with the abutment block 420. The abutment block 420 contacts the elastic plate 520 to compress it, causing the end of the elastic plate 520 to press against a pressure sensor. The current position of the movable mechanism 400 is determined based on the force applied to the pressure sensor. This configuration allows for accurate detection of the position of the movable block 410, improving detection precision and ensuring the operating handle is in place. Furthermore, the elastic plate 520 provides a limiting effect, restricting the movement of the movable block 410.
[0053] For ease of understanding, assume that the circuit is closed when the abutment block 420 is in contact with both upper detection components 500 simultaneously, and open when the abutment block 420 is in contact with both lower detection components 500 simultaneously. Taking the upward movement of the movable block 410 as an example, the initial state is open, meaning the movable block 410 is below, and the abutment block 420 is in contact with the two lower detection components 500. After receiving a closing signal, the movable block 410 moves upward. When both upper detection components 500 detect contact with the abutment block 420, the circuit is considered closed. By setting two detection components 500 above and below the abutment block 420, the positions of the abutment block 420 and the movable block 410 can be accurately located when the abutment block 420 is in contact with both detection components 500 simultaneously. Furthermore, the two elastic plates 520 enhance the limiting effect on the abutment block 420. In some other embodiments, the topmost and bottommost detection components 500 can be used to detect the extreme positions of the moving mechanism 400 (exceeding these positions will cause damage to the operating handle). If the other two detection components 500 fail, when the abutment block 420 contacts the topmost or bottommost detection component 500, it controls the moving mechanism 400 to stop moving, so as to avoid excessive movement of the moving mechanism 400 that could damage the operating handle.
[0054] Furthermore, the side of the abutment block 420 that contacts the elastic plate 520 is beveled so that the abutment block 420 and the elastic plate 520 can contact each other. If the structure is set with sharp edges, it will cause damage due to collision. This can effectively avoid the abutment block 420 and the elastic plate 520 from colliding and being damaged.
[0055] In some embodiments, the transmission assembly 300 includes a plurality of transmission gears 310 and a rotating shaft 320, the rotating shaft 320 being connected to the drive mechanism 200, and the gears 310 being connected to the rotating shaft 320; the movable mechanism 400 also includes a rack 430, the rack 430 being connected to the movable block 410, the length direction of the rack 430 being set along a predetermined direction and cooperating with the gears 310.
[0056] See Figure 1 and Figure 2 A rack 430 is located on the side of the movable block 410 near the transmission assembly 300 and is arranged vertically. One end of a rotating shaft 320 is connected to the drive mechanism 200, and one gear 310 is located at the other end of the rotating shaft 320. The rotating shaft 320 drives the gear 310 to rotate, and multiple gears mesh sequentially. Another gear 310 meshes with the rack 430 to drive the movable block 410 to move vertically. By adjusting the rotation direction of the gear 310, the movement direction of the movable block 410 can be controlled. This arrangement allows the movable block 410 to move vertically and stably.
[0057] In some embodiments, the electric opening and closing device further includes a clutch mechanism 600, and there are various possibilities for the arrangement of the clutch mechanism 600.
[0058] For example, the drive mechanism 200 is connected to the transmission assembly 300 through the clutch mechanism 600. The clutch mechanism 600 is used to drive the transmission assembly 300 to move relative to the drive mechanism 200, so that the drive mechanism 200 and the transmission assembly 300 are connected or separated. When the transmission assembly 300 and the drive mechanism 200 are connected, the drive mechanism 200 drives the movable mechanism 400 to move.
[0059] For example, part of the structure of the transmission assembly 300 is connected to another part of the structure of the transmission assembly 300 through the clutch mechanism 600. The clutch mechanism 600 is used to drive part of the structure of the transmission assembly 300 to move relative to the other part of the structure of the transmission assembly 300, so that the structures of the transmission assembly 300 are connected or separated. When the structures of the transmission assembly 300 are connected, the drive mechanism 200 drives the movable mechanism 400 to move.
[0060] For example, the movable mechanism 400 is connected to the transmission assembly 300 through the clutch mechanism 600. The clutch mechanism 600 is used to drive the transmission assembly 300 to move relative to the movable mechanism 400, so that the movable mechanism 400 and the transmission assembly 300 are connected or separated. When the transmission assembly 300 and the movable mechanism 400 are connected, the drive mechanism 200 drives the movable mechanism 400 to move.
[0061] See Figure 1 and Figure 2 The clutch mechanism 600 is located between one part of the transmission assembly 300 and another part of the transmission assembly 300. The clutch mechanism 600 can connect or separate the structures of the transmission assembly 300, thereby adjusting the connection between the drive mechanism 200 and the movable mechanism 400. When one part of the transmission assembly 300 is connected to the other part of the transmission assembly 300, the drive mechanism 200 can drive the movable mechanism 400 to move. When one part of the transmission assembly 300 is separated from the other part of the transmission assembly 300, the drive mechanism 200 cannot drive the movable mechanism 400 to move. In the closed state, the drive mechanism 200 and the transmission assembly 300 cannot restrict the movement of the movable mechanism 400 and the operating handle, thus avoiding safety accidents caused by the operating handle failing to trip normally.
[0062] For ease of understanding, when this electric circuit breaker is in use, upon receiving a closing signal, the clutch mechanism 600 connects the internal structure of the transmission assembly 300, and the drive mechanism 200 drives the movable mechanism 400 to move the operating handle in the closing direction. When the movable mechanism 400 reaches the closing position, the control component controls the clutch mechanism 600 to separate one part of the transmission assembly 300 from the other part. At this time, the movable mechanism 400 is not restricted by the transmission assembly 300 and the drive mechanism 200. In this state, if a trip occurs, the movable mechanism 400 will not restrict the movement of the operating handle in the opening direction. Through the above settings, when circuit breaker operation is required, the clutch mechanism 600 connects one part of the transmission assembly 300 to the other part, allowing the drive mechanism 200 to drive the movable mechanism 400. After the circuit breaker operation is completed, the clutch mechanism 600 separates one part of the transmission assembly 300 from the other part, releasing the drive mechanism 200 from restricting the operating handle and preventing safety accidents caused by the operating handle's inability to trip.
[0063] In some embodiments, the clutch mechanism 600 includes an electromagnetic clutch.
[0064] Preferably, the clutch mechanism 600 is an electromagnetic clutch, which can respond quickly.
[0065] In some embodiments, the mounting bracket 100 is provided with a plurality of limiting members 110, which are provided for the movable mechanism 400 and are used to limit the range of motion of the movable mechanism 400.
[0066] See Figure 1 and Figure 3 Limiting elements 110 are located at the upper and lower ends of the mounting bracket 100 to abut against the movable mechanism 400. This arrangement prevents the movable mechanism 400 from moving too much and damaging the operating handle.
[0067] In some embodiments, the limiting member 110 includes two limiting plates 111, both of which are connected to the mounting bracket 100. The two limiting plates 111 are respectively located on both sides of the movable mechanism 400 in a predetermined direction, and the limiting plates 111 abut against the movable mechanism 400.
[0068] See Figure 1 and Figure 3 The mounting bracket 100 is provided with a limiting plate 111 at both the upper and lower ends, which is arranged in the horizontal direction. The limiting plate 111 can abut against the movable mechanism 400 to prevent the movable mechanism 400 from moving too much.
[0069] It should be noted that the elastic plate 520 of the detection component 500 in this embodiment has a limiting function, which can prevent the movement range of the movable mechanism 400 from being too large. The limiting plate 111 is used to prevent the movable mechanism 400 from moving further when the limiting of the detection component 500 fails, so as to improve the safety of use.
[0070] In some embodiments, the mounting bracket 100 is further provided with a guide rail 120, the length direction of the guide rail 120 is set along a predetermined direction; the movable mechanism 400 is slidably connected to the guide rail 120 and slides along the length direction of the guide rail 120.
[0071] See Figure 1 and Figure 3 Two guide rails 120 are provided, which are vertically arranged on the left and right sides of the movable mechanism 400, respectively. The drive mechanism 200 drives the movable mechanism 400 to move along the length of the guide rails 120 through the transmission component 300, thereby driving the operating handle to move. Through the above arrangement, it can be ensured that the movable mechanism 400 moves in a predetermined direction and avoids deviation of the movable mechanism 400 during movement.
[0072] In some embodiments, the drive mechanism 200 includes a motor 210, the output shaft of which is connected to the transmission assembly 300.
[0073] Preferably, the drive mechanism 200 is a motor 210, which can stably drive the movement of the movable mechanism 400, and is easy to obtain and operate.
[0074] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0075] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
