Description

Technical Field

[0001] The present application relates to the technical field of display devices, and in particular to a smart blackboard. Background Art

[0002] Smart blackboards usually include a smart board as an independent machine and a mobile panel that can record blackboard writing. The mobile panel is located on one side of the smart board. The smart board and the mobile panel transmit data through signal lines, so that the blackboard content can be displayed on the smart board.

[0003] At present, when the mobile panel of the smart blackboard is slid left and right, in order to ensure reliable data transmission between the mobile panel and the smart board, an elastic signal line (such as a spiral telescopic signal line mounted on a guide rod) is usually used to connect the mobile panel and the smart board. However, due to the tension generated when the elastic signal line is stretched, the mobile panel will be pulled to slide toward the smart board after being unfolded, blocking the display screen of the smart board, thereby affecting user operation and reducing user experience. Summary of the invention

[0004] The present application provides a smart blackboard that can solve the problem that the mobile panel of the existing smart blackboard blocks the display screen of the smart board after being unfolded, affecting user operation and reducing user experience.

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

[0006] The smart panel assembly comprises a smart panel, a frame and a guide rail, wherein the smart 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 through the guide rail, and the movable panel can move between a position of shielding the smart panel and a position of revealing the smart panel;

[0008] An elastic signal line, both ends of which are connected to the smart panel assembly and the movable panel respectively, and exerts a force on the movable panel to move toward the position that shields the smart panel; and

[0009] The locking mechanism comprises a locking component and a coupling component, wherein the locking component is movably connected to the frame and has a locking position and an unlocking position; the coupling component is connected to the movable panel and is configured to drive the locking component to move to the locking position or the unlocking position; wherein the locking component is engaged with the coupling component at the locking 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 mobile panel and a locking component movably connected to the frame, when the user pushes the mobile panel, the mobile panel can drive the coupling component, thereby driving the locking component to move to the locked position or unlocked position, that is, after the locking component is driven to the preset locked or unlocked position by the coupling component, the locking component and the coupling component cooperate with each other to achieve locking or unlocking, and when the locking component moves to the locked position, it engages with the coupling component to limit the mobile panel to the position where the smart board is exposed. Therefore, this solution can avoid the difficulty of the mobile panel of the smart blackboard to remain in the position where the smart board is exposed after it is unfolded, and block the display screen of the smart board, which is convenient for user operation and effectively improves the user experience.

[0029] The technical solution in the present application will be described clearly and in detail below in conjunction with the accompanying drawings. In the description of the embodiments of the present application, unless otherwise specified, " / " means or, for example, A / B can mean A or B: "and / or" in the text is only a description of the association relationship of associated objects, indicating that there can be three relationships, for example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone. In addition, in the description of the embodiments of the present application, "multiple" means two or more than two.

[0030] In the following, the terms "first" and "second" are used for descriptive purposes only and are not to be understood as suggesting or implying 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 the features.

[0031] In the related art, a smart blackboard usually includes a smart board as an independent whole machine and a mobile panel capable of recording blackboard writing, and the mobile panel is located on one side of the smart board. The smart board and the mobile panel transmit data through a signal line, so that the blackboard writing content can be displayed on the smart board.

[0032] At present, when the mobile panel of the smart blackboard is slid left and right, in order to ensure reliable data transmission between the mobile panel and the smart board, an elastic signal line (such as a spiral telescopic signal line mounted on a guide rod) is usually used to connect the mobile panel and the smart board. However, due to the tension generated when the elastic signal line is stretched, the mobile panel will be pulled to slide toward the smart board after being unfolded, blocking the display screen of the smart board, thereby affecting user operation and reducing user experience.

[0033] In order to solve the above technical problems, an embodiment of the present application provides a smart blackboard, which can prevent the mobile panel of the smart blackboard from blocking the display screen of the smart board after being unfolded, facilitates user operation, and effectively improves the user experience.

[0034] Please refer to Figure 1 and Figure 2 The smart blackboard provided in the embodiment of the present application includes a smart large board component 1, a movable panel 2, an elastic 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 through the guide rail 121, and the movable panel 2 can move between a position that blocks 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 a force is applied to the movable panel 2 to move toward the position that blocks 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 locking position and an unlocking position; the coupling component 32 is connected to the movable panel 2, and is configured to drive the locking component 31 to move to a locking position or an unlocking position; wherein the locking component 31 is engaged with the coupling component 32 at the locking position to limit the movable panel 2 to a position that exposes the smart panel 11.

[0036] In actual use, the smart board 11 can be used as the main screen of the smart blackboard, and the mobile panel 2 can be used as the secondary screen of the smart blackboard. The smart board 11 can be a large screen, or a flat panel with display and touch functions, for example, it can be an organic light emitting diode (OLED) display screen, an active matrix organic light emitting diode or an active matrix organic light emitting diode (AMOLED) display screen, a mini organic light emitting diode (miniorganic light emitting diode) display screen, a micro organic light emitting diode (micro organic light emitting diode) display screen, a micro organic light emitting diode (micro organic light emitting diode) display screen, a quantum dot light emitting diode (QLED) display screen, a liquid crystal display (LCD) and other display devices, and of course the smart board 11 can also be a handwriting board, etc. The mobile panel 2 is a writing board with a writing and recording function, and the user writes on the mobile panel 2, for example, the mobile panel 2 can be a display screen made of a liquid crystal film. When the mobile panel 2 is connected to the smart board 11 in communication, the blackboard content recorded on the mobile panel 2 can be displayed on the smart board 11, thereby providing the user with a larger operation and writing space.

[0037] like Figure 1 and Figure 2 As shown, the frame 12 and the guide rail 121 create conditions for the relative movement between the smart panel 11 and the mobile panel 20. The frame 12 encloses the area where the smart panel 11 and the mobile panel 20 are installed. Exemplarily, the guide rail 121 is arranged on the back of the frame 12 and extends in the left and right directions 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 and the like.

[0038] The present application may provide two movable panels 2, which are symmetrically arranged on the left and right sides of the smart panel 11. Each movable panel 2 is locked in the position of revealing the smart panel 11 by the above-mentioned locking mechanism 3. The movable panel 2 can be connected to the guide rail 121 through structures such as pulleys and sliders, so as to limit the moving path of the movable panel 2, and enable the movable panel 2 to move between a position away from the smart panel 11 to reveal the smart panel 11 and a position close to the smart panel 11 to block the smart panel 11. During the movement of the movable panel 2, the movable panel 2 and the smart panel 11 can be stacked in the front-to-back direction, so that when the position of blocking the smart panel 11 is reached, the movable panel 2 moves to the front of the smart panel 11 to at least partially cover the smart panel 11. Generally speaking, at this time, the two movable panels 2 completely cover half of the smart panel 11, thereby achieving full shielding of the smart panel 11. When revealing the position of the smart board 11, the two mobile panels 2 are staggered from the smart board 11 in the front-to-back direction to reveal the smart board 11. Thus, during the switching process of the mobile panels 2 between different positions, the state of the entire smart blackboard also changes accordingly.

[0039] The two ends of the elastic signal line are respectively connected to the smart large panel assembly 1 and the mobile panel 2, and apply a force to the mobile panel 2 to move toward the position of blocking the smart large panel 11. It should be noted that in order to ensure the reliable transmission of data between the mobile panel 2 and the smart large panel 11, the two ends of the elastic signal line are usually connected to the mobile panel 2 and the smart large panel 11 respectively, so as to avoid the signal line from being pulled and failing. However, in this case, the elastic signal line will continue to apply a force in the opposite direction to the mobile panel 2 when the mobile panel 2 is unfolded, making it difficult for the mobile panel 2 to remain in a position that exposes the smart large panel 11 after unfolding, and blocking the display screen of the smart large panel 11, affecting user operation, and reducing user experience. The present application, by setting a locking mechanism 3, stabilizes the mobile panel 2 in a position that exposes the smart large panel 11, effectively overcoming the above problems.

[0040] like Figure 2 As shown, the locking mechanism 3 includes a locking assembly 31 and a coupling assembly 32. The locking assembly 31 is movably connected to the frame 12 and has a locking position and an unlocking position relative to the frame 12. The movable connection between the locking assembly 31 and the frame 12 is a flexible connection, which can smoothly receive the coupling assembly 32. The locking assembly 31 can be engaged with the coupling assembly 32 when in the locked position, and can be separated from the coupling assembly 32 when in the unlocked position.

[0041] The coupling component 32 is connected to the mobile 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 mobile panel 2 to move, the coupling component 32 moves synchronously, and in the process of the coupling component 32 moving, it acts on the locking component 31, so that the locking component 31 moves to the locked position and engages with the coupling component 32, and also moves to the unlocked position and separates from the coupling component 32.

[0042] In one embodiment, the locking component 31 is engaged with the coupling component 32 in the locked position to limit the movable panel 2 to a position where the smart board 11 is exposed. There are multiple structural forms in which the locking component 31 and the coupling component 32 are engaged. In one possible implementation, a ratchet pawl structure can be adopted. In another possible implementation, a detachably connected hook structure can also be adopted, etc. When the locking component 31 is engaged with the coupling component 32 in the locked position, the movable panel 2 can be limited to a position where the smart board 11 is exposed, so as to prevent the movable panel 2 of the smart blackboard from blocking the display screen of the smart board 11 after being unfolded.

[0043] Based on the smart blackboard in the embodiment of the present application, through the coupling component 32 connected to the mobile panel 2, and the locking component 31 movably connected to the frame 12, when the user pushes the mobile panel 2, the mobile panel 2 can drive the coupling component 32, thereby driving the locking component 31 to move in the locked position or unlocked position, that is, after the locking component 31 is driven to the preset locked or unlocked position by the coupling component 32, the locking component 31 and the coupling component 32 cooperate with each other to achieve locking or unlocking, and when the locking component 31 moves to the locked position, it is engaged with the coupling component 32 to limit the mobile panel 2 to the position where the smart board 11 is exposed. Therefore, this solution can avoid the mobile panel 2 of the smart blackboard from being difficult to maintain in the position where the smart board 11 is exposed after it is unfolded, and the display screen of the smart board 2 is blocked, which is convenient for user operation and effectively improves the user experience.

[0044] In addition, when the existing smart blackboard is installed, if the installation level requirement is not high, the mobile panel 2 will block the display screen of the smart large board 11 over a large area, which seriously affects the user experience. Therefore, relatively high requirements are currently put forward for the installation of existing smart blackboards. The smart blackboard provided by the present application can keep the mobile panel 2 in a position to expose the smart large board 11 after it is unfolded by setting a locking mechanism 3, and can be used normally even when the installation is tilted, thereby effectively reducing the installation requirements and after-sales costs.

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

[0046] The locking member 311 is used to realize the engagement with the coupling assembly 32. Figure 4 As shown, the locking member 311 is provided with a slot 3112, and the locking member 311 is swingably arranged on the side of the frame 12 away from the smart panel 11. Among them, the embodiment of the present application does not specifically limit the shape of the slot 3112, and the designer can flexibly design it according to factors such as the difficulty of processing and actual needs. It can be understood that the locking member 311 has a swing center, and the swing center avoids the movement path of the coupling component 32. For example, the swing center can be on any one of the opposite sides 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 a locked position or an unlocked position during the swinging process. When the locking member 311 swings to the locked position, it engages with the coupling component 32 to limit the mobile panel 2 to a 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 to release the restriction on the mobile panel 2.

[0047] like Figure 3 As shown, the two ends of the first return spring 312 are respectively connected to the frame 12 and the locking member 311. The first return spring 312 can be a telescopic spring. Of course, the first return spring 312 can also be a torsion spring. For the specifications, dimensions, stiffness coefficient and other parameters of the first return spring 312, designers can flexibly design and select according to factors such as user needs and the actual installation conditions of the smart blackboard. Further, the initial state of the first return spring 312 of the present application is a stretched state, so that the locking member 311 has a movement tendency to reset to the locked position. During use, the user can apply force to the mobile panel 2. During the sliding process of the mobile panel 2 to the position where the smart board 11 is exposed, the coupling component 32 drives the locking member 311 to swing around its swing center. At this time, the locking member 311 is out of the locked position, so that the coupling component 32 can smoothly enter the slot 3112 to achieve the engagement with the locking member 311. During the above process, the first return spring 312 is further stretched and further energy is stored. When the movable panel 2 reaches the position where the smart panel 11 is exposed, the first return spring 312 releases its elastic potential energy, and after the user's external force is removed, it can drive the locking member 311 to swing and return to the locked position, thereby firmly limiting the coupling assembly 32 at the locked position, and also allowing the movable panel 2 to stably stay at the position where the smart panel 11 is exposed.

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

[0049] In order to realize the connection between the positioning member 321 and the movable panel 2, as shown in FIG. Figure 2 and Figure 3 As shown, in some embodiments of the present application, the coupling assembly 32 also includes a bracket 323 and a plug-in board 322. The bracket 323 is set above the frame 12, one side of which is fixedly connected to the movable panel 2, and the other side is provided with a slider or a running wheel adapted to the guide rail 121; the end of the plug-in board 322 close to the smart board 11 is connected to the bracket 323, and the positioning member 321 is fixedly connected to the end of the plug-in board 322 away from the smart board 11. Among them, the bracket 323 and the plug-in board 322 can be fixedly connected by screws, welding, etc., and the length of the plug-in board 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 by a slider or a running wheel. In the embodiment of the present application, the connection between the positioning member 321 and the mobile panel 2 can be achieved through the bracket 323 and the plug-in plate 322, so that when the user pushes the mobile panel 2, the positioning member 321 is driven to move, and when the positioning member 321 moves to a position where the smart panel 11 is exposed, the positioning member 321 can be engaged with the card slot 3112 of the locking member 311, thereby limiting the mobile panel 2 to a position where the smart panel 11 is exposed.

[0050] In some embodiments of the present 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; the slot 3112 is formed between the two protrusions 3111; the extension length of one of the two protrusions 3111 away from the smart board 11 is greater than the extension length of the other protrusion 3111. Among them, the embodiments of the present application do not specifically limit the shape and material of the base 3110 and the protrusion 3111, and the designer can reasonably design and select the shape and material of the base 3110 and the protrusion 3111 according to factors such as the difficulty of processing, 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. In the process of releasing the locking assembly 31 from the coupling assembly 32, as shown in FIG. Fig.12 As shown, the user only needs to push the movable panel 2 to the right with force, and the movable panel 2 will drive the positioning member 321 to move to the right. When the positioning member 321 moves to the right at a speed reduced to zero under the tension of the elastic signal line and then moves to the left, the positioning member 321 can slide and separate from the protrusion 3111 with a longer extension length on the right side, and is no longer blocked by the protrusion 3111 with a shorter extension length on the left side. Therefore, it will not fall into the slot 3112 between the two protrusions 3111, so that the locking component 31 and the coupling component 32 can be quickly and conveniently released, so that the movable panel 2 moves to a position to block 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 position or the unlocked position, in order to make the sliding movement between the positioning member 321 and the locking member 311 smoother, as shown in FIG. Figure 4 As shown, in some embodiments of the present application, the two protrusions 3111 are opposite to each other and form a transition slope 3113 on the outer side, and the transition slope 3113 is adjacent to the notch of the slot 3112 and is used to slide with the positioning member 321. Figure 4 As shown in , 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 according to tests and other methods. In the embodiment of the present application, when the positioning member 321 contacts and slides with the protrusion 3111 with a shorter extension length, the transition slope 3113 can smoothly fall into the card slot 3112 of the locking member 311, thereby realizing the card connection between the locking component 31 and the coupling component 32; when the positioning member 321 contacts and slides with the protrusion 3111 with a longer extension length, the transition slope 3113 can smoothly slide over the protrusion 3111, thereby realizing the separation of the locking component 31 and the coupling component 32.

[0053] In the above process, in order to improve the user's operational feel of pushing the movable panel 2, in some embodiments of the present application, a damping member is provided between the locking member 311 and the frame 12. The damping member can be in the form of a friction plate, etc., and the two opposite surfaces of the damping member are in friction contact with the locking member 311 and the frame 12 respectively, so as to adjust the tightness of the swinging motion of the locking member 311. In this way, the external force required to drive the locking member 311 to swing can be adjusted through the damping member. Users can obtain a variety of different push-pull feel to meet the needs of different customers.

[0054] Considering that the user may push the mobile panel 2 too hard, the coupling component 32 may move too far away from the smart panel 11. Figure 3As shown, in some embodiments of the present application, the locking mechanism 3 further includes a limit assembly 33; the limit assembly 33 is connected to the frame 12 and is located on the side of the locking member 311 away from the smart panel 11 to limit the distance that the coupling assembly 32 moves in the direction away from the smart panel 11. The limit assembly 33 can be fixedly connected to the frame 12 or movably connected to the frame 12. When the limit assembly 33 is fixedly connected to the frame 12, the limit assembly 33 only serves to limit the movement of the coupling assembly 32 in the direction away from the smart panel 11, and when the limit assembly 33 is movably connected to the frame 12, for example, by using the flexible connection of the telescopic member, the coupling assembly 32 can also be buffered, thereby increasing the service life of the coupling assembly 32.

[0055] Considering that in the process of locking the locking component 31 and the coupling component 32 to restrict the movable panel 2 to the position where the smart panel 11 is exposed, the positioning member 321 will contact the locking member 311 and drive the locking member 311 to rotate, see Figures 6 to 9 In order to prevent the locking member 311 from rotating at an excessive angle, Figure 3 , Figure 5 , Figures 6 to 9 As shown, in some embodiments of the present application, the limiting assembly 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, and the first direction is perpendicular to the moving direction of the positioning member 321; the limiting plate 331 includes a plate body 3311 and a bending portion 3312; the plate body 3311 is spaced apart from the frame 12, and the bending portion 3312 is arranged at one end of the plate body 3311 close to 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, so that the limiting plate 331 is reset to the initial position. Among them, the plate body 3311 is spaced apart from the frame 12, which can reserve the necessary position space for the bending 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 second return spring 332 and the limit plate 331 are connected above the connection point, and of course, they can also be connected below the connection point of the second return spring 332 and the limit plate 331. The specific connection position can be determined by the designer according to factors such as the spatial layout of the locking mechanism 3. Figures 6 to 9 As shown, after the locking member 311 rotates a preset angle, it contacts the bent portion 3312 of the limiting plate 331, and then the limiting plate 331 moves downward a certain distance. When it rotates to the maximum angle, the locking member 311 no longer continues to rotate under the action of the elastic signal line and the second return spring 332, but reverses, and at the same time, the limiting plate 331 returns to its initial position.

[0056] like Figure 3As shown, in some embodiments of the present application, the limit assembly 33 also includes a guide pin 333, and the guide pin 333 is fixedly connected to the frame 12; the plate body 3311 is provided with a guide hole 3313 matching the guide pin 333. Among them, the present application embodiment does not specifically limit the material, shape structure, and size of the guide pin 333 and the guide hole 3313. 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 the embodiment of the present application, by setting matching guide pins 333 and guide holes 3313, the limit plate 331 can be moved a predetermined length along a predetermined direction, thereby controlling the moving distance of the limit plate 331, which plays a role in limiting the rotation angle of the locking member 311.

[0057] In order to effectively limit the distance that the coupling component 32 moves away from the smart board 11, Figure 3 and Figure 5 As shown, in some embodiments of the present application, the limiting assembly 33 further includes a stopper plate 334, which is located on the moving path of the positioning member 321; the stopper plate 334 is connected to the free end of the bending portion 3312, and an avoidance notch 3341 is provided at one end of the stopper plate 334 close to the bending portion 3312. The avoidance notch 3341 can have a variety of shapes, for example, a rectangular notch can be used, so that the stopper plate 334 is formed as follows: Figure 3 and Figure 5 The inverted L-shaped structure shown in the figure, of course, the avoidance gap 3341 can also be an inverted U-shaped gap, etc., and the present application does not make specific limitations on this. The stop plate 334 of the present application can effectively limit the distance that the coupling component 32 moves away from the smart panel 11. On the one hand, when the user pushes the movable panel 2, the positioning member 321 is driven to move to the position where the smart panel 11 is exposed, such as Figure 7 As shown, the stop plate 334 is located in the moving path of the positioning member 321 to limit the distance that the coupling assembly 32 moves away from the smart panel 11; on the other hand, when the user pushes the mobile panel 2, the positioning member 321 is driven to move to the unlocking position. Fig.11 As shown, the edge of the avoidance gap 3341 of the stop plate 334 can limit the distance that the coupling component 32 moves in the direction away from the smart panel 11 .

[0058] The following content will be based on the above introduction and combined with the accompanying drawings to explain in detail the specific changes of the locking mechanism 3 during the movement of the mobile panel 2 of the present application.

[0059] See also Figure 1 and Figure 6, the user pushes the movable panel 2, and the movable panel 2 drives the positioning member 321 to move to the right, that is, the user drives the movable panel 2 to move toward the position where the smart panel 11 is exposed. The movable panel 2 drives the positioning member 321 in the coupling assembly to approach 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 presses against the bent portion 3312 on the limit plate 331. See FIG. Figure 7 When the positioning member 321 slides along the transition slope 3113 to a position directly opposite to the notch of the locking slot 3112, the positioning member 321 is temporarily separated from the locking member 311, and the locking member 311 swings to the left under the action of the first return spring 312. At the same time, the positioning member 321 is acted upon by the reverse pulling force of the elastic signal line, and when its speed of moving to the right is reduced to zero, it turns to move to the left; see Figure 8 and Fig. 9 The positioning member 321 moved to the left falls into the slot 3112 of the locking member 311, thereby realizing the engagement between the locking assembly 31 and the coupling assembly 32. During this process, the limiting plate 331 and the stop plate 334 in the limiting assembly 33 are reset under the action of the second reset spring 332.

[0060] When the movable panel 2 moves from the position of revealing the smart panel 11 to the position of shielding the smart panel 11, it is necessary to unlock the locking mechanism 3. Fig.10 The user first drives the movable panel 2 to move rightward, and the locking member 311 swings toward the right due to the force of the positioning member 321. Finally, the positioning member 321 escapes from the slot 3112 and enters the avoidance notch 3341 on the stop plate 334 (such as Fig.11 ), during which the first return spring 312 is also deformed and drives the locking member 311 to return to the locked position. Fig.12 Then, under the action of the elastic signal line, the movable panel 2 moves toward the position of shielding the smart panel 11, and 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. Fig.13 The positioning member 321 finally slides along the transition slope 3113 on the longer protrusion 3111 to a position disengaged from the locking member 311, that is, the locking member 311 swings to the left to the unlocking position. At this time, the locking mechanism 3 no longer has a restrictive effect on the positioning member 311, and the movable panel 2 can slide smoothly to the position of shielding the smart panel 11, and the locking member 311 will be reset to the locked position again under the action of the first reset spring 312.
