Description

Technical Field

[0001] This application relates to the field of display device technology, and in particular to a smart blackboard. Background Technology

[0002] A smart blackboard typically consists of a standalone smart board and a movable panel for recording notes, with the movable panel located on one side of the smart board. The smart board and the movable panel transmit data via signal cables, allowing the written content to be displayed on the smart board.

[0003] Currently, to ensure reliable data transmission between the movable panel and the smart blackboard when sliding the movable panel left and right, a flexible signal cable (such as a spiral telescopic signal cable mounted on a guide rod) is typically used to connect the movable panel and the smart board. However, because the elastic signal cable generates tension when it extends, the movable panel will be pulled towards the smart board after unfolding, obstructing the display screen of the smart board, thus affecting user operation and reducing the user experience. Summary of the Invention

[0004] This application provides a smart blackboard that solves the problem that the movable panel of existing smart blackboards obstructs the display screen of the smart board after it is unfolded, affecting user operation and reducing the user experience.

[0005] This application provides a smart blackboard, including:

[0006] The intelligent large panel assembly includes an intelligent large panel, a frame, and a guide rail. The intelligent large panel is fixedly connected to the frame, and the guide rail is fixed to the frame.

[0007] A movable panel is movably connected to the frame via the guide rail, and the movable panel can move between a position that obscures the smart panel and a position that exposes the smart panel.

[0008] A flexible signal line, with its two ends connected to the smart panel assembly and the movable panel respectively, applies a force to the movable panel, causing it to move toward the position that obstructs the smart panel; and

[0009] A locking mechanism includes a locking component and a coupling component. The locking component is movably connected to the frame and has a locked position and an unlocked position. The coupling component is connected to the movable panel and configured to drive the locking component to move to the locked position or the unlocked position. The locking component engages with the coupling component in the locked position to restrict the movable panel to the position where the smart panel is exposed.

[0010] In the above technical solution, by setting a coupling component connected to the movable panel and a locking component movably connected to the frame, when the user pushes the movable panel, the movable panel moves the coupling component, thereby driving the locking component to a locked or unlocked position. That is, after the coupling component drives the locking component to the preset locked or unlocked position, the locking component and the coupling component cooperate to lock or unlock. Furthermore, when the locking component moves to the locked position, it engages with the coupling component, restricting the movable panel to the position where the smart whiteboard is exposed. Therefore, this solution avoids the problem of the movable panel of the smart whiteboard being difficult to keep in the position where the smart whiteboard is exposed after it is unfolded, thus preventing obstruction of the smart whiteboard's display screen, facilitating user operation, and effectively improving the user experience.

[0029] The technical solutions in this application will be clearly and thoroughly described below with reference to the accompanying drawings. In the description of the embodiments of this application, unless otherwise stated, " / " means "or," for example, A / B can mean A or B. "And / or" in the text is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone. Furthermore, in the description of the embodiments of this application, "multiple" refers to two or more than two.

[0030] Hereinafter, the terms "first" and "second" are used for descriptive purposes only and should not be construed as implying or suggesting relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

[0031] In related technologies, a smart blackboard typically consists of a standalone smart board and a movable panel for recording blackboard writing, with the movable panel located on one side of the smart board. The smart board and the movable panel transmit data via signal cables, enabling the blackboard content to be displayed on the smart board.

[0032] Currently, to ensure reliable data transmission between the movable panel and the smart blackboard when sliding the movable panel left and right, a flexible signal cable (such as a spiral telescopic signal cable mounted on a guide rod) is typically used to connect the movable panel and the smart board. However, because the elastic signal cable generates tension when it extends, the movable panel will be pulled towards the smart board after unfolding, obstructing the display screen of the smart board, thus affecting user operation and reducing the user experience.

[0033] To address the aforementioned technical issues, this application provides a smart blackboard that avoids the smart blackboard's movable panel obstructing the display screen after unfolding, facilitating user operation and effectively improving the user experience.

[0034] Please refer to the following: Figure 1 and Figure 2 The smart blackboard provided in this application embodiment includes a smart board assembly 1, a movable panel 2, a flexible signal line (not shown) and a locking mechanism 3.

[0035] The smart panel assembly 1 includes a smart panel 11, a frame 12, and a guide rail 121. The smart panel 11 is fixedly connected to the frame 12, and the guide rail 121 is fixed to the frame 12. The movable panel 2 is movably connected to the frame 12 via the guide rail 121, and the movable panel 2 can move between a position that obscures the smart panel 11 and a position that exposes the smart panel 11. The two ends of the elastic signal line are respectively connected to the smart panel assembly 1 and the movable panel 2, and apply a force to the movable panel 2 toward the position that obscures the smart panel 11. The locking mechanism 3 includes a locking component 31 and a coupling component 32. The locking component 31 is movably connected to the frame 12 and has a locked position and an unlocked position. The coupling component 32 is connected to the movable panel 2 and is configured to drive the locking component 31 to move to the locked position or the unlocked position. In the locked position, the locking component 31 engages with the coupling component 32 to restrict the movable panel 2 to the position that exposes the smart panel 11.

[0036] In practical use, the smart large board 11 can serve as the main screen of the smart blackboard, while the movable panel 2 serves as the secondary screen. The smart large board 11 can be a large screen or a tablet with display and touch functions. For example, it can be an organic light-emitting diode (OLED) display, an active matrix organic light-emitting diode (AMOLED) display, a mini organic light-emitting diode (MLED) display, a micro organic light-emitting diode (MOLED) display, a quantum dot light-emitting diode (QLED) display, or a liquid crystal display (LCD). Of course, the smart large board 11 can also be a writing tablet. The movable panel 2 is a writing tablet with writing and recording functions. Users write on the movable panel 2; for example, the movable panel 2 can be a display made of liquid crystal film. When the mobile panel 2 is connected to the smart board 11, the whiteboard content recorded on the mobile panel 2 can be displayed on the smart board 11, thus providing users with a larger space for operation and writing.

[0037] like Figure 1 and Figure 2 As shown, the frame 12 and guide rail 121 create conditions for relative movement between the smart panel 11 and the movable panel 20. The frame 12 encloses the area where the smart panel 11 and the movable panel 20 are installed. For example, the guide rail 121 is disposed on the back of the frame 12 and extends in the left-right direction of the frame 12. The smart panel 11 is fixedly connected to the frame 12, and the guide rail 121 is fixed to the frame 12. In this application, the smart panel 11 and the guide rail 121 are fixedly connected to the frame 12, and the fixed connection method includes, but is not limited to, threaded connection, bonding, welding, etc.

[0038] This application provides two movable panels 2, symmetrically arranged on the left and right sides of the smart panel 11. Each movable panel 2, when locked in the locked position by the aforementioned locking mechanism 3, remains in the position of exposing the smart panel 11. The movable panels 2 can be connected to the guide rail 121 via pulleys, sliders, or other structures, thereby limiting the movement path of the movable panels 2 and allowing them to move between the position of exposing the smart panel 11 away from it and the position of obscuring it. During the movement of the movable panels 2, they can overlap with the smart panel 11 in the front-back direction. When obscuring the smart panel 11, the movable panels 2 move to the front of the smart panel 11 to at least partially cover it. Typically, at this time, the two movable panels 2 each completely cover half of the smart panel 11, thus achieving full obscuring of the smart panel 11. When the position of the smart blackboard 11 is revealed, the two movable panels 2 are offset from the smart blackboard 11 in the front-back direction to reveal the smart blackboard 11. Thus, the state of the entire smart blackboard changes as the movable panels 2 switch to different positions.

[0039] The two ends of the elastic signal line are connected to the smart panel assembly 1 and the movable panel 2, respectively, and exert a force on the movable panel 2 towards the position where it obstructs the smart panel 11. It should be noted that, to ensure reliable data transmission between the movable panel 2 and the smart panel 11, the two ends of the elastic signal line are typically connected to both the movable panel 2 and the smart panel 11 to prevent the signal line from failing due to tension. However, in this case, the elastic signal line continuously exerts a counter-force on the movable panel 2 when it is unfolded, making it difficult for the movable panel 2 to remain in the position where the smart panel 11 is exposed after unfolding, thus obstructing the display screen of the smart panel 11, affecting user operation, and reducing the user experience. This application overcomes the above problems by setting a locking mechanism 3 to stabilize the movable panel 2 in the position where the smart panel 11 is exposed.

[0040] like Figure 2 As shown, the locking mechanism 3 includes a locking component 31 and a coupling component 32. The locking component 31 is movably connected to the frame 12 and has a locked position and an unlocked position relative to the frame 12. The movable connection between the locking component 31 and the frame 12 is a flexible connection, which can smoothly support the coupling component 32. When the locking component 31 is in the locked position, it can engage with the coupling component 32, and when the locking component 31 is in the unlocked position, it can disengage from the coupling component 32.

[0041] The coupling component 32 is connected to the movable panel 2 and is configured to drive the locking component 31 to move to the locked position or the unlocked position. In other words, as the user pushes the movable panel 2, the coupling component 32 moves synchronously, and during the movement of the coupling component 32, it acts on the locking component 31, which can engage with the coupling component 32 when the locking component 31 moves to the locked position, or disengage from the coupling component 32 when the locking component 31 moves to the unlocked position.

[0042] In one embodiment, the locking component 31 engages with the coupling component 32 in the locked position to restrict the movable panel 2 to the position where the smart whiteboard 11 is exposed. The engagement structure between the locking component 31 and the coupling component 32 can take various forms. One possible implementation uses a ratchet and pawl mechanism, while another uses a detachable hook structure, and so on. When the locking component 31 is in the locked position, it engages with the coupling component 32, restricting the movable panel 2 to the position where the smart whiteboard 11 is exposed, preventing the movable panel 2 from obstructing the display screen of the smart whiteboard 11 when it is unfolded.

[0043] Based on the smart blackboard in this embodiment, through the coupling component 32 connected to the movable panel 2 and the locking component 31 movably connected to the frame 12, when the user pushes the movable panel 2, the movable panel 2 drives the coupling component 32, thereby driving the locking component 31 to move in the locked or unlocked position. That is, after the coupling component 32 drives the locking component 31 to the preset locked or unlocked position, the locking component 31 and the coupling component 32 cooperate to lock or unlock. When the locking component 31 moves to the locked position, it engages with the coupling component 32, restricting the movable panel 2 to the position where the smart board 11 is exposed. Therefore, this solution can avoid the problem of the movable panel 2 of the smart blackboard being difficult to keep in the position where the smart board 11 is exposed after it is unfolded, thus avoiding obstructing the display screen of the smart board 2, facilitating user operation, and effectively improving the user experience.

[0044] Furthermore, with existing smart blackboards, if the installation level is not high, the movable panel 2 may significantly obstruct the display screen of the smart panel 11, severely impacting the user experience. Therefore, current smart blackboard installations have relatively high requirements. The smart blackboard provided in this application, however, uses a locking mechanism 3 to keep the movable panel 2 unfolded and positioned to expose the smart panel 11, allowing for normal use even when installed at an angle. This effectively reduces installation requirements and after-sales costs.

[0045] Please refer to the reference. Figures 2 to 4 In some embodiments of this application, the locking component 31 includes a first return spring 312 and a locking member 311.

[0046] Locking element 311 is used to achieve engagement with coupling component 32. For example... Figure 4 As shown, the locking member 311 is provided with a slot 3112, and the locking member 311 is swayably disposed on the side of the frame 12 away from the smart panel 11. In this embodiment, the shape of the slot 3112 is not specifically limited; designers can flexibly design it according to factors such as ease of processing and actual needs. It is understood that the locking member 311 has a swing center, and this swing center avoids the movement path of the coupling component 32. For example, the swing center can be on either side of the opposite side of the movement path of the coupling component 32. The locking member 311 can be connected to the frame 12 by a pin connection, and can reach either the locked or unlocked position during the swing. When the locking member 311 swings to the locked position, it engages with the coupling component 32, restricting the movable panel 2 to the position where the smart panel 11 is exposed. When the locking member 311 swings to the unlocked position, it separates from the coupling component 32, releasing the restriction on the movable panel 2.

[0047] like Figure 3 As shown, the two ends of the first return spring 312 are connected to the frame 12 and the locking member 311, respectively. The first return spring 312 can be a telescopic spring, or it can be a torsion spring. Designers can flexibly design and select the specifications, dimensions, stiffness coefficient, and other parameters of the first return spring 312 based on user needs and the actual installation conditions of the smart blackboard. Furthermore, the initial state of the first return spring 312 in this application is a stretched state, so that the locking member 311 has a tendency to return to the locked position. During use, the user can apply force to the moving panel 2. As the moving panel 2 slides towards the position where the smart blackboard 11 is exposed, it drives the coupling component 32 to drive the locking member 311 to swing around its swing center. At this time, the locking member 311 disengages from the locked position, allowing the coupling component 32 to smoothly enter the slot 3112 to engage with the locking member 311. During the above process, the first return spring 312 is further stretched and stores energy. When the moving panel 2 reaches the position of the exposed smart panel 11, the first return spring 312 releases elastic potential energy, which can drive the locking member 311 to swing and return to the locked position after the user's external force is removed. In this way, the coupling component 32 is firmly limited in the locked position, and the moving panel 2 is stably stopped at the position of the exposed smart panel 11.

[0048] Specifically, the coupling component 32 includes a positioning member 321 fixedly connected to the movable panel 2; when the positioning member 321 moves with the movable panel 2 to the position where the smart panel 11 is exposed, it contacts the locking member 311 and falls into the slot 3112. The structure of the positioning member 321 matches the structure of the slot 3112 to achieve this. Figure 3For example, when the slot 3112 is a U-shaped groove, the locking member 311 can be a cylindrical positioning pin. Of course, designers can also design flexibly according to actual needs and relevant standards and specifications. That is to say, when the user pushes the movable panel 2, the movable panel 2 can drive the positioning member 321 to move. When the positioning member 321 moves to the position where the smart panel 11 is exposed, it engages with the slot 3112 of the locking member 311, thereby restricting the movable panel 2 to the position where the smart panel 11 is exposed.

[0049] To achieve the connection between the positioning component 321 and the movable panel 2, such as Figure 2 and Figure 3 As shown, in some embodiments of this application, the coupling component 32 further includes a bracket 323 and an insert plate 322. The bracket 323 is mounted above the frame 12, with one side fixedly connected to the movable panel 2 and the other side having a slider or wheel adapted to the guide rail 121. The end of the insert plate 322 near the smart board 11 is connected to the bracket 323, and the positioning member 321 is fixedly connected to the end of the insert plate 322 away from the smart board 11. The bracket 323 and the insert plate 322 can be fixedly connected by screws, welding, or other methods. The length of the insert plate 322 can be flexibly designed according to different models of smart blackboards. One side of the bracket 323 can be fixedly connected to the movable panel 2 by screws, and the other side is movably connected to the guide rail 121 via a slider or wheel. In this embodiment, the positioning member 321 and the movable panel 2 can be connected through the bracket 323 and the insert plate 322. When the user pushes the movable panel 2, the positioning member 321 is moved. When the positioning member 321 moves to the position where the smart panel 11 is exposed, the positioning member 321 can be engaged with the slot 3112 of the locking member 311, thus restricting the movable panel 2 to the position where the smart panel 11 is exposed.

[0050] In some embodiments of this application, the locking member 311 includes a base 3110 and two protrusions 3111. The two protrusions 3111 are located at one end away from the swing center of the base 3110 and extend in a direction away from the swing center. A slot 3112 is formed between the two protrusions 3111. The extension length of one protrusion 3111 away from the smart panel 11 is greater than the extension length of the other protrusion 3111. In this application, the shape and material of the base 3110 and the protrusions 3111 are not specifically limited. Designers can reasonably design and select the shape and material of the base 3110 and the protrusions 3111 based on factors such as processing difficulty, cost, and weight.

[0051] In this embodiment, see Figure 4 The extension length of the protrusion 3111 on the right side of the locking member 311 is greater than the extension length of the protrusion 3111 on the left side. During the process of releasing the locking assembly 31 from the coupling assembly 32, such as... Figure 12 As shown, the user only needs to push the movable panel 2 to the right, and the movable panel 2 will drive the positioning member 321 to move to the right. When the speed of the positioning member 321 moving to the right is reduced to zero under the action of the elastic signal line, it will turn to move to the left. The positioning member 321 can slide and separate from the protrusion 3111 with a longer extension on the right side. It is no longer blocked by the protrusion 3111 with a shorter extension on the left side. Therefore, it will not fall into the slot 3112 between the two protrusions 3111. Thus, the locking component 31 and the coupling component 32 can be quickly and conveniently released, and the movable panel 2 can be moved to the position that blocks the smart panel 11.

[0052] Considering that the positioning member 321 contacts and slides with the locking member 311 when it moves to the locked or unlocked position, in order to make the sliding movement between the positioning member 321 and the locking member 311 smoother, such as Figure 4 As shown, in some embodiments of this application, two protrusions 3111 are formed with transition slopes 3113 opposite to their outer surfaces. The transition slopes 3113 are adjacent to the slot of the slot 3112 and are used for sliding engagement with the positioning member 321. For example Figure 4 As shown, a transition slope 3113 is provided on the left side of the left protrusion 3111, and a transition slope 3113 is provided on the right side of the right protrusion 3111. The inclination angle of the transition slope 3113 can be determined through experiments or other methods. In this embodiment, when the positioning member 321 contacts and slides against the shorter protrusion 3111, it can smoothly fall into the slot 3112 of the locking member 311 through the transition slope 3113, thus achieving the engagement of the locking component 31 and the coupling component 32; when the positioning member 321 contacts and slides against the longer protrusion 3111, it can smoothly slide over the protrusion 3111 through the transition slope 3113, thus achieving the separation of the locking component 31 and the coupling component 32.

[0053] In the above process, to improve the user's tactile feedback when pushing the movable panel 2, in some embodiments of this application, a damping element is provided between the locking member 311 and the frame 12. The damping element can be in the form of a friction plate, etc., with its two opposing surfaces rubbing against the locking member 311 and the frame 12 respectively. This allows adjustment of the tightness of the swinging motion of the locking member 311. Thus, the external force required to drive the locking member 311 to swing can be adjusted through the damping element. This allows users to obtain various different push-pull sensations to meet the needs of different customers.

[0054] Considering that the user may push the movable panel 2 too forcefully, causing the coupling component 32 to move too far away from the smart panel 11, such as... Figure 3As shown, in some embodiments of this application, the locking mechanism 3 further includes a limiting component 33; the limiting component 33 is connected to the frame 12 and located on the side of the locking member 311 away from the smart panel 11, to limit the distance the coupling component 32 can move in the direction away from the smart panel 11. The limiting component 33 can be fixedly connected to the frame 12 or movably connected to the frame 12. When the limiting component 33 is fixedly connected to the frame 12, it only serves to limit the movement of the coupling component 32 in the direction away from the smart panel 11. When the limiting component 33 is movably connected to the frame 12, for example using a flexible connection via a telescopic member, it can also buffer the coupling component 32, thereby improving its service life.

[0055] Considering that during the process of locking component 31 and coupling component 32 engaging and restricting the movable panel 2 to the position where the smart panel 11 is exposed, positioning component 321 will contact locking component 311 and drive locking component 311 to rotate, see [reference]. Figures 6 to 9 To prevent the locking element 311 from rotating too much, such as Figure 3 , Figure 5 , Figures 6 to 9 As shown, in some embodiments of this application, the limiting component 33 includes a limiting plate 331 and a second return spring 332. The limiting plate 331 is slidably connected to the frame 12 and can move relative to the frame 12 along a first direction, which is perpendicular to the moving direction of the positioning member 321. The limiting plate 331 includes a plate body 3311 and a bent portion 3312. The plate body 3311 is spaced apart from the frame 12, and the bent portion 3312 is located at one end of the plate body 3311 near the positioning member 321. The two ends of the second return spring 332 are respectively connected to the frame 12 and the limiting plate 331 to reset the limiting plate 331 to its initial position. The spaced-apart arrangement of the plate body 3311 and the frame 12 provides necessary space for the bent portion 3312. One end of the second return spring 332 is connected to the limiting plate 331, and the other end is connected to the frame 12. It can be understood that the connection point between the second return spring 332 and the frame 12 can be... Figure 3 The connection point is located above the point where the second return spring 332 connects to the limiting plate 331. Alternatively, it could be below the point where the second return spring 332 connects to the limiting plate 331. The specific connection position can be determined by the designer based on factors such as the spatial layout of the locking mechanism 3. For example... Figures 6 to 9 As shown, after the locking member 311 rotates to a preset angle, it contacts the bent portion 3312 of the limiting plate 331. Then the limiting plate 331 moves downward a certain distance. When it rotates to the maximum angle, the locking member 311 stops rotating under the action of the elastic signal line and the second reset spring 332, and instead reverses. At the same time, the limiting plate 331 resets to the initial position.

[0056] like Figure 3As shown, in some embodiments of this application, the limiting component 33 further includes a guide pin 333, which is fixedly connected to the frame 12; the plate 3311 is provided with a guide hole 3313 that matches the guide pin 333. In this application embodiment, the material, shape, structure, and size of the guide pin 333 and the guide hole 3313 are not specifically limited. Designers can reasonably design and select the shape and material of the guide pin 333 and the guide hole 3313 according to different models of smart blackboards. In this application embodiment, by setting matching guide pins 333 and guide holes 3313, the limiting plate 331 can move a predetermined distance along a predetermined direction, thereby controlling the moving distance of the limiting plate 331 and limiting the rotation angle of the locking member 311.

[0057] To effectively limit the distance that the coupling component 32 moves away from the smart board 11, such as Figure 3 and Figure 5 As shown, in some embodiments of this application, the limiting component 33 further includes a stop plate 334, which is located on the moving path of the positioning member 321. The stop plate 334 is connected to the free end of the bent portion 3312, and a clearance notch 3341 is provided at one end of the stop plate 334 near the bent portion 3312. The clearance notch 3341 can have various shapes, such as a rectangular notch, thereby forming the stop plate 334 as shown in the figure. Figure 3 and Figure 5 The inverted L-shaped structure shown can also be replaced by an inverted U-shaped notch, etc., and this application does not specifically limit this. The stop plate 334 of this application can effectively limit the distance the coupling component 32 can move away from the smart panel 11. On the one hand, when the user pushes the movable panel 2, during the process of moving the positioning member 321 to the position where the smart panel 11 is exposed, such as... Figure 7 As shown, the stop plate 334 located on the moving path of the positioning member 321 can limit the distance the coupling component 32 moves away from the smart panel 11; on the other hand, when the user pushes the moving panel 2, during the process of moving the positioning member 321 to the unlock position, such as Figure 11 As shown, the edge of the clearance notch 3341 of the stop plate 334 can limit the distance that the coupling component 32 can move in the direction away from the smart panel 11.

[0058] The following content will, based on the above description and in conjunction with the accompanying drawings, provide a detailed explanation of the specific changes in the locking mechanism 3 during the movement of the movable panel 2 in this application.

[0059] See Figure 1 and Figure 6The user pushes the movable panel 2, which causes the positioning member 321 to move to the right, i.e., the user drives the movable panel 2 to move towards the position where the smart panel 11 is exposed. The movable panel 2 causes the positioning member 321 in the coupling assembly to move closer to the locking member 311. When the positioning member 321 contacts the locking member 311, the positioning member 321 contacts the transition slope 3113 on the shorter protrusion 3111 and applies an external force to the locking member 3111 to drive the locking member 3111 to swing to the right. At this time, the longer protrusion 3111 in the locking member 311 abuts against the bent portion 3312 on the limiting plate 331. See also Figure 7 When the positioning member 321 slides along the transition slope 3113 to the position directly opposite the slot of the slot 3112, the positioning member 321 and the locking member 311 briefly separate. Under the action of the first return spring 312, the locking member 311 swings to the left. At the same time, the positioning member 321 is subjected to the reverse tension of the elastic signal line. When its speed of moving to the right decreases to zero, it turns to move to the left. See also Figure 8 and Figure 9 The positioning component 321, which moves to the left, falls into the slot 3112 of the locking component 311, thereby locking the locking component 31 and coupling component 32. During this process, the limiting plate 331 and the stop plate 334 in the limiting component 33 are reset under the action of the second reset spring 332.

[0060] When the movable panel 2 moves from the position exposing the smart panel 11 to the position obscuring the smart panel 11, and the locking mechanism 3 needs to be unlocked, refer to... Figure 10 The user first drives the movable panel 2 to move to the right. Due to the force of the positioning member 321, the locking member 311 swings to the right. Finally, the positioning member 321 disengages from the slot 3112 and enters the clearance notch 3341 on the stop plate 334 (e.g., ...). Figure 11 During this process, the first return spring 312 also deforms and drives the locking member 311 to return to the locked position. Figure 12 Next, under the action of the elastic signal line, the movable panel 2 moves toward the position that blocks the smart panel 11. The positioning member 321 first contacts the transition slope 3113 on the longer protrusion 3111 and pushes the locking member 311 to swing to the left. Figure 13 The positioning member 321 eventually slides along the transition slope 3113 on the longer protrusion 3111 to the position where it is disengaged from the locking member 311. That is, the locking member 311 swings to the left to the unlock position. At this time, the locking mechanism 3 no longer restricts the positioning member 311, and the moving panel 2 can smoothly slide to the position that blocks the smart panel 11. The locking member 311 will be reset to the locked position again under the action of the first reset spring 312.
