Referring to fig. 1 to 8, an embodiment of the present invention provides an intelligent blackboard 10, which includes a first display screen 100 and a second display screen 200, wherein the first display screen 100 is connected to a position to be installed, and the first display screen 100 and the second display screen 200 are arranged along a horizontal direction. One of the first display screen 100 and the second display screen 200 may constitute a main screen and the other one may constitute a sub-screen for presentation of teaching contents. In the present embodiment, the first display 100 constitutes a main screen, and the second display 200 constitutes a sub-screen. The position to be mounted of the first display screen 100 may be a wall, a movable stand, etc.

It is understood that the number of the second display screens 200 may be plural, for example, two (not shown), and arranged at both sides of the first display screen 100, respectively. The present embodiment is described by taking a second display 200 as an example. Wherein, the side of the first display screen 100 adjacent to the second display screen 200 is used for installing the open-plug specification module.

To facilitate the assembly and disassembly of the OPS module, in some embodiments, the intelligent blackboard 10 includes a connecting assembly, the connecting assembly includes a first supporting member 310 and a second supporting member 320, the first supporting member 310 is connected to a position to be installed of the intelligent blackboard 10, for example, the first supporting member 310 is connected to a wall through a threaded fastener, and the connecting stability is high. The second supporting member 320 is connected to the second display screen 200, for example, the second supporting member 320 is connected to the second display screen 200 by a screw fastener, so that the connection stability is high.

For edge-mounting and dismounting the OPS module, the second supporting member 320 is rotatably connected to the first supporting member 310, so that the second display panel 200 can rotate relative to the first display panel 100, so as to switch the second supporting member 320 between the hanging state and the inclined state. When the second supporting member 320 is in the hanging state, the adjacent edges of the second display screen 200 and the first display screen 100 are flush with each other, that is, the first display screen 100 and the second display screen 200 are aligned in the vertical direction and the horizontal direction, and along the vertical direction of the first display screen 100, there is no step difference between the first display screen 100 and the second display screen 200. At this time, the first display 100 and the second display 200 are in a state in which teaching is possible. When the second supporting member 320 is in the inclined state, a first included angle b is formed between the plane where the second display screen 200 is located and the plane where the first display screen 100 is located, and the size of the first included angle b may be 1 to 50 degrees, that is, the second display screen 200 is arranged to be inclined relative to the position to be installed.

In some embodiments, to provide the operation space, the second support 320 is configured to move back and forth in a direction approaching to or departing from the first support 310 in an inclined state, i.e., to move the second display 200 back and forth relative to the first display 100, so as to provide an adjustable distance between the first display 100 and the second display 200.

That is, by moving the second display screen 200, the side of the first display screen 100 adjacent to the second display screen 200 can be exposed in the field of view of the user, and the OPS module interface of the first display screen 100 has a certain operation space, so that the user can conveniently mount and dismount the OPS module.

Like this, under the condition of not dismouting second display screen 200 connection structure, can be with the horizontal cartridge of OPS module in the side of first display screen 100, convenient operation, and can avoid the OPS module to drop, avoided setting up exposed electric connecting wire at the rear side of wisdom blackboard 10 simultaneously, the security is higher.

It can be understood that, when the user needs the dismouting OPS module, the user can at first the application of force drive second display screen 200 and rotate first display screen 100 relatively, so that second display screen 200 converts the tilt state into by the state that articulates, then the application of force drives the second display screen 200 translation under the tilt state, until second display screen 200 removes to the one side of keeping away from first display screen 100, at this moment, the OPS module interface of first display screen 100 exposes in user's the field of vision, the user can carry out the dismouting of OPS module. Then, the user can apply a force to drive the second display screen 200 in the tilted state to translate until the second display screen 200 moves to a position adjacent to the first display screen 100, and then the tilted state of the second display screen 200 is switched to the hanging state.

In some embodiments, the number of the connecting components may be multiple, the second display screen 200 is connected to the position to be installed through the multiple connecting components, and the connection stability of the second display screen 200 is high.

In some embodiments, the first display screen 100 may also be connected to a location to be installed (not shown) through the above-mentioned connection assembly, and at this time, a user may selectively move the first display screen 100 or the second display screen 200 as needed to detach and install the OPS module.

The second display screen 200 and the rotation connection structure at the position to be installed may include a rotation shaft and a rotation shaft groove, and the rotation shaft is located in the rotation shaft groove and can rotate relative to the rotation shaft groove.

In some possible embodiments, the first supporting member 310 is provided with a supporting portion 311, the second supporting member 320 is provided with a hanging portion 321, the hanging portion 321 is provided with an opening, and the supporting portion 311 extends into the hanging portion 321 and abuts against an inner wall surface of the hanging portion 321, so that the second supporting member 320 is hung on the first supporting member 310. Like this, can be equipped with the connection structure of approximate couple on the second support piece 320, the portion 321 that couples constitutes the inner chamber of this couple structure, and the user can couple second support piece 320 on supporting part 311 through application of force lifting second display screen 200, perhaps makes supporting part 311 and the portion 321 that couples break away from, and the structure is comparatively simple, easy dismounting.

At this time, the cross-sectional size of the supporting portion 311 may be smaller than the cross-sectional size of the hanging portion 321 such that a movable gap a is formed between a sidewall surface of the supporting portion 311 and an inner wall surface of the hanging portion 321, and the second supporter 320 is configured to rotate with the supporting portion 311 as a rotational support. For example, the supporting portion 311 may be a plate-shaped or a strip-shaped structure. In this way, the second supporting member 320 can rotate relative to the first supporting member 310 by taking the hanging position as a support, that is, the user can push and pull the second display screen 200 towards the side close to or far from the installation position, so as to drive the second display screen 200 to rotate relative to the first display screen 100, which is labor-saving for the user and convenient for operation.

In some embodiments, the axis of rotation of the second display 200 may extend in any direction. For example, the rotation axis of the second display screen 200 is in the vertical direction, and the rotation connection structure is located on the side of the second display screen 200 far away from the first display screen 100. And the translation direction of the second display screen 200 relative to the first display screen 100 can also be in any direction, for example, the second display screen 200 can move upwards in a vertical direction or move upwards in a tilted direction.

In some possible embodiments, the rotation center line of the second display panel 200 and the translation direction of the second display panel 200 may be along a horizontal direction, and in particular, the extending direction of the supporting portion 311 is parallel to the arrangement direction L of the first display panel 100 and the second display panel 200, so that the second supporting member 320 has a rotation center line parallel to the arrangement direction L. In order to avoid interference between the second display 200 and the position to be installed, at this time, the first support 310 and the second support 320 may be disposed on the top of the second display 200. That is, the user can drive the bottom of the second display screen 200 by applying a force to move the bottom of the second display screen 200 toward a side close to or far from the position to be installed, so that the second display screen 200 rotates relative to the first display screen 100.

And the supporting portion 311 extending along the arrangement direction L constitutes a rail structure for guiding the second supporter 320 to reciprocate toward or away from the first supporter 310. That is, the user can push and pull the second display screen 200 in the horizontal direction, so that the second display screen 200 moves toward the side close to or far away from the first display screen 100, which is labor-saving.

Both ends of the supporting portion 311 are connected to the first support 310. In some embodiments, the first support member 310 is a beam, and the support portion 311 may be a thin-wall structure (not shown) protruding out of the top wall surface of the beam, and the hook structure of the second support member 320 is hooked on the top wall surface of the first support member 310. Alternatively, the top wall surface of the cross beam is provided with a recessed structure, so that the side walls of the recessed structure form a supporting portion 311 (as shown in fig. 3 to 7), the recessed structure extends along the arrangement direction L, at this time, the recessed structure is hung on the supporting portion 311, and part of the hook structure extends into the recessed structure.

The extending length of the supporting portion 311 is greater than or equal to the reciprocating stroke of the second supporting member 320, so as to avoid the supporting portion 311 limiting the movement of the second supporting member 320.

When the extension length of the supporting portion 311 is the same as the reciprocating stroke of the second supporting member 320, and the user applies force to drive the second display screen 200 to reciprocate, the hanging portion 321 contacts with the end portions (e.g., the wall surfaces at the two ends of the recessed structure) of the supporting portion 311, so as to remind the user of moving in place, and the operation is convenient.

It can be understood that, when the second display screen 200 is supported at the side of the first display screen 100 in an inclined state, the space between the first display screen 100 and the second display screen 200 is large, i.e. the operating space for the user to move is large, and the operation is easy for the user.

In order to fix the second display screen 200 at the side of the first display screen 100 in an inclined state, the second display screen 200 may be provided with a movable support rod, for example, one end of the support rod is rotatably connected to the second display screen 200, and the other end of the support rod is supported on a wall, and when the second display screen 200 is in a hanging state, the support rod is received and fixed at the rear side of the second display screen 200.

The hanging portion 321 may have a substantially U-shaped cross section. In some possible embodiments, the inner wall surfaces of the hanging part 321 include a first inner wall surface 3211 and a second inner wall surface 3212, and a second included angle c is formed between the first inner wall surface 3211 and the second inner wall surface 3212, i.e., the cross-sectional shape of the hanging part 321 is approximately V-shaped. In this way, when the supporting portion 311 abuts on the intersection position of the first inner wall surface 3211 and the second inner wall surface 3212, that is, when the second supporter 320 is hung on the first supporter 310, the top position of the first supporter 310 abuts on the intersection position of the first inner wall surface 3211 and the second inner wall surface 3212, and the second supporter 320 can rotate relative to the first supporter 310 by using the abutting position as a rotational support.

In some embodiments, the second included angle c is greater than or equal to the rotation stroke of the second supporting member 320, so as to prevent the hanging portion 321 from restricting the rotation of the second supporting member 320.

When the second included angle c is the same as the rotation stroke of the second supporting member 320, the supporting portion 311 may be a plate-shaped structural member for facilitating the operation of the user, such that when the second display screen 200 is in the hanging state, one of the first inner wall surface 3211 and the second inner wall surface 3212 contacts one inner wall surface of the supporting portion 311, and when the second display screen 200 is in the inclined state, the other of the first inner wall surface 3211 and the second inner wall surface 3212 contacts the other inner wall surface of the supporting portion 311. That is, the supporting portion 311 is configured to limit the second display 200, so as to prevent the second display 200 from shaking. Meanwhile, when the user applies force to drive the second display screen 200 to switch between the hanging state and the inclined state, when the supporting portion 311 contacts with the inner wall surface of the hanging portion 321, the user can be reminded to rotate in place, and the operation is convenient.

In some possible embodiments, the second support 320 may also be fixed in an inclined state relative to the first support 310 at a position away from the first display screen 100.

Specifically, the first supporting member 310 is provided with a protruding abutting portion 330, and the abutting portion 330 is located at one end of the supporting portion 311 away from the first display screen 100. The abutting portion 330 is integrally formed with the first supporting member 310, and the sum of the extension length of the abutting portion 330 in the arrangement direction L and the extension length of the second supporting member 320 in the arrangement direction L is smaller than the extension length of the supporting portion 311.

The abutting portion 330 may be located above the supporting portion 311, at this time, the second supporting member 320 is provided with a first avoiding surface 322 and a second avoiding surface 323, an included angle is formed between the first avoiding surface 322 and the second avoiding surface 323 to form an avoiding region for accommodating the abutting portion 330, that is, the avoiding region is a recessed region formed on the second supporting member 320, so that the abutting portion 330 may extend into or extend out of the avoiding region in the moving process of the second supporting member 320.

When the user drives the second display screen 200 in the tilted state to move toward one end of the abutting portion 330, the second supporting member 320 can move to a position below the abutting portion 330. At this time, the user releases the second display screen 200, the second display screen 200 tends to rotate under the action of its own weight, and the first avoiding surface 322 is used to abut against the bottom wall surface of the abutting portion 330, so that the second supporting member 320 in the inclined state is limited between the abutting portion 330 and the supporting portion 311, that is, the second supporting member 320 abuts against the lower side of the abutting portion 330, so that the second display screen 200 can be supported at the position to be mounted in the inclined state.

In some embodiments, the abutting portion 330 is connected to the supporting portion 311, and when the abutting portion 330 and the supporting portion 311 are integrally molded, the thickness of the end of the supporting portion 311 away from the first display screen 100 is increased and is equal to the cross-sectional size of the hanging portion 321, so that the abutting portion 330 and the supporting portion 311 can be commonly sandwiched between the inner wall surfaces of the hanging portion 321. That is, by the abutment between the abutment portion 330 and the inner wall surface of the hanging portion 321, the movable gap a between the outer wall surface of the whole of the abutment portion 330 and the supporting portion 311 and the inner wall surface of the hanging portion 321 is set to zero, so that the second display 200 is supported in an inclined state at the position to be mounted.

It can be understood that when the second display screen 200 is supported at the position to be mounted in an inclined state, a first included angle b between the second display screen 200 and the first display screen 100 is defined by the hanging portion 321, and at this time, the rotation stroke of the second supporting member 320 is greater than or equal to the first included angle b.

That is, when the rotation stroke of the second supporting member 320 is the same as the first included angle b, and the rotation stroke of the second supporting member 320 is the same as the second included angle c, when the user drives the second display screen 200 in the inclined state to move, the second display screen 200 needs to be maintained in the state of the first included angle b, so as to avoid that the inclination angle of the second display screen 200 changes due to the change of the force applied by the user, and the second supporting member 320 interferes with the abutting portion 330.

When the rotation stroke of the second supporting member 320 is greater than the first included angle b, the user drives the second display screen 200 to move, the second display screen 200 is allowed to have a certain rotation allowance, the user is labor-saving, at this time, after the user drives the second display screen 200 to move in place, the user releases the second display screen 200, the bottom wall of the second display screen 200 can move towards the side of the position to be installed by a partial distance, namely, the second display screen 200 falls back by a certain angle, for example, 3-5 degrees, so that the second supporting member 320 is prevented from interfering with the abutting portion 330, and the operation is convenient.

In some embodiments, a buffer, such as a rubber pad, a silicone pad, or the like, may be disposed at a position where the second supporting member 320 contacts the abutting portion 330 to buffer the second display screen 200.

Referring to fig. 2, 9 and 10, in some possible embodiments, in order to prevent the second display screen 200 from shaking relative to the position to be installed when the second display screen 200 is in the hanging state, the intelligent blackboard 10 further includes a clamping assembly, the clamping assembly includes a first clamping member 410 and a second clamping member 420, the first clamping member 410 is used for being connected with one of the second display screen 200 and the position to be installed, and the second clamping member 420 is used for being connected with the other of the second display screen 200 and the position to be installed.

In the present embodiment, the first clamping member 410 is connected to the position to be mounted, and the second clamping member 420 is connected to the second display screen 200, for example, the first clamping member 410 is detachably connected to the position to be mounted by a threaded fastener, and the second clamping member 420 is detachably connected to the second display screen 200 by a threaded fastener.

The first clamping member 410 further has an accommodating portion 413, and the accommodating portion 413 has an opening capable of opening and closing. The second clamping member 420 is configured to extend into the first clamping member 410 when the second display screen 200 is in the hanging state, so that the first clamping member 410 is clamped on the outer wall surface of the second clamping member 420.

That is, when the second display panel 200 is switched from the tilted state to the hanging state, the second clamping member 420 can enter the accommodating portion 413 through the opening, and at this time, the first clamping member 410 is clamped on the outer wall surface of the second clamping member 420, so that the first clamping member 410 and the second clamping member 420 are relatively fixed, that is, the second display panel 200 is connected and fixed to the position to be mounted, and the second display panel 200 has high fixing stability.

It can be understood that when the second display panel 200 is switched from the hanging state to the inclined state, the user can apply a force to resist the friction force between the first holding member 410 and the second holding member 420, and drive the second display panel 200 to rotate, so that the second holding member 420 comes out of the accommodating portion 413 through the opening, i.e. the first holding member 410 and the second holding member 420 are separated.

In some embodiments, the number of the clamping assemblies may be multiple, and the multiple clamping assemblies are spaced apart from each other to improve the fixing stability of the second display screen 200.

To facilitate automatic opening and closing of the opening, the first clamping member 410 may have elasticity. In some possible embodiments, the first clamp 410 includes a first clamp arm 411 and a second clamp arm 412, and at least one of the first clamp arm 411 and the second clamp arm 412 is an elastic member. For example, the first clamping arm 411 and the second clamping arm 412 are both elastic members, so that the second clamping member 420 can be clamped and fixed in the accommodating portion 413 more stably.

The area enclosed by the first holding arm 411 and the second holding arm 412 forms an accommodating portion 413, and an opening is formed between the free end of the first holding arm 411 and the free end of the second holding arm 412.

Thus, the second clipping member 420 can be abutted against the free ends of the first clipping arm 411 and the second clipping arm 412, and resist the elastic force of the first clipping arm 411 and the second clipping arm 412, so that the opening is opened and enters the accommodating part 413 through the opening. At this time, the first and second clipping arms 411, 412 can respectively abut against the outer wall surface of the second clipping element 420 under the action of their own elastic force, that is, the first and second clipping arms 411, 412 clip and fix the second clipping element 420, so that the second display panel 200 and the first display panel 100 are relatively fixed.

In order to facilitate the second clamping member 420 to extend into the accommodating portion 413, the ends of the first clamping arm 411 and the second clamping arm 412 may be provided with a lead-in slope, so that the second clamping member 420 may abut against the lead-in slope, and during the process of the first clamping member 410 and the second clamping member 420 approaching each other, the first clamping arm 411 and the second clamping arm 412 are moved away from each other, so that the second clamping member 420 extends into the accommodating portion 413.

Considering that the supporting portion 311 extends along the horizontal direction, the first clamping arm 411 and the second clamping arm 412 may be spaced along the horizontal direction, so that after the second clamping member 420 extends into the accommodating portion 413, the clamping assembly and the connecting assembly may together form a limit for the second display 200.

In some embodiments, the first and second gripper arms 411, 412 are juxtaposed in a vertical direction. Thus, when the second display screen 200 is in the hanging state, the user can manually drive the second display screen 200 to move along the supporting portion 311, so that the first clamping member 410 and the second clamping member 420 can relatively move along the horizontal direction, and the position of the second display screen 200 along the horizontal direction can be adjusted.

It is understood that the extension lengths of the first clamping member 410 and the second clamping member 420 along the arrangement direction L may be equivalent (as shown in fig. 9). Alternatively, the extension length of the first clamping member 410 along the arrangement direction L is greater than the extension length of the second clamping member 420 along the arrangement direction L (as shown in fig. 10), so as to prevent the second clamping member 420 from falling out of the accommodating portion 413 along the arrangement direction L.

Wherein, a spring or the like may be disposed on the first holding arm 411 and the second holding arm 412. In order to simplify the structure of the first clamping member 410, in some possible embodiments, the first clamping arm 411 and the second clamping arm 412 may be both metal sheets with elastic members, so that the first clamping arm 411 and the second clamping arm 412 may be both fixedly connected to the position to be installed, and the structure is simple and the manufacturing cost is low. At this time, the second clamping member 420 may be a block structure, and the structure is relatively simple.

In some embodiments, the metal sheet can be bent, for example, referring to fig. 9 and 10, the metal sheet can be bent in a wave shape to increase the elasticity of the metal sheet and prevent the metal sheet from being bent and broken.

In order to improve the fixing stability between the first clamping member 410 and the second clamping member 420, in some possible embodiments, the size of the opening is smaller than that of the accommodating portion 413, and the shape of the second clamping member 420 is matched with the shape of the inner wall surface of the accommodating portion 413.

Specifically, the second connector includes a first portion and a second portion connected to each other, the first portion having a size larger than that of the second portion, and the second portion being used to connect with the second display screen 200. When the second clamping member 420 extends into the accommodating portion 413, the first portion extends into the accommodating portion 413, and the second portion is located at the opening.

That is, the free end of the first holding arm 411 and the free end of the second holding arm 412 are hooked with the wall surface of the first portion close to the second portion, respectively, that is, when the second holding member 420 is separated from the first holding member 410, not only the friction between the first holding arm 411 and the second holding member 420 and between the second holding arm 412 and the second holding member 420, but also the elastic force of the first holding arm 411 and the second holding arm 412 are overcome, so as to swing the first holding arm 411 and the second holding arm 412, thereby improving the fixing stability of the first holding member 410 and the second holding member 420.

When the first and second clamping members 410 and 420 are metal sheets, the metal sheets may be approximately L-shaped (not shown). In some embodiments, the two metal sheets may also be obliquely disposed toward one side close to each other (as shown in fig. 9 and 10).

In some possible embodiments, the intelligent blackboard 10 further includes a locking member 430, and the first clamping member 410 is provided with a communicating portion for communicating the inner side and the outer side of the accommodating portion 413, that is, the communicating portion may be a through hole structure penetrating through the metal sheet, and the communicating portion may be provided on at least one of the first clamping arm 411 and the second clamping arm 412. The lock member 430 is connected to the second clamp member 420 via a communication portion. The locking member 430 may be a locking pin, a threaded fastener, or the like. Thus, the locking member 430 can pass through the communicating portion to be fixedly connected with the second clamping member 420, at this time, the first clamping member 410 and the second clamping member 420 are connected into a whole, so that the second clamping member 420 can be prevented from being separated from the first clamping member 410 under the external force collision, and the fixing stability of the second display screen 200 is high.

It can be understood that coupling assembling and centre gripping subassembly can all be hidden between the display screen and treat the mounted position, and the outward appearance of wisdom blackboard 10 is comparatively succinct.

Referring to fig. 2 and 11 to 15, in some possible embodiments, the intelligent blackboard 10 further includes a limiting component, the limiting component includes a first limiting member 510 and a clamping portion 521, the first limiting member 510 is connected to one of the first display screen 100 and the second display screen 200 and extends toward the other one of the first display screen 100 and the second display screen 200, the clamping portion 521 is located on the other one of the first display screen 100 and the second display screen 200, and the clamping portion 521 is recessed.

In the present embodiment, the first limiting member 510 is disposed on the second display screen 200, and the fastening portion 521 is disposed on the first display screen 100. The engaging portion 521 may be formed on a rear case of the first display screen 100. In some embodiments, a second limiting member 520 may be disposed on the first display screen 100, the second limiting member 520 is detachably connected to the first display screen 100, and the fastening portion 521 is disposed on the second limiting member 520.

The first limiting member 510 is provided with a protruding limiting portion 511, and the limiting portion 511 is used for extending into the fastening portion 521 and fastening with the fastening portion 521 when the second display screen 200 is in a hanging state.

Thus, after the second display screen 200 is connected to the to-be-mounted position through the connecting assembly, the first display screen 100 and the second display screen 200 can be connected through the limiting assembly, so that the relative position between the first display screen 100 and the second display screen 200 is limited, and the first display screen 100 is aligned with the second display screen 200, that is, a gap in the horizontal direction between the first display screen 100 and the second display screen 200 is avoided, or a section difference in the vertical direction of the first display screen 100 is avoided between the first display screen 100 and the second display screen 200.

The shape of the limiting portion 511 and the clamping portion 521 can be set as required, for example, the cross section of the clamping portion 521 is rectangular, so as to limit the horizontal direction and the vertical direction of the first display screen 100 at the same time.

In some embodiments, when the supporting portion 311 extends in a horizontal direction and the first holding arm 411 and the second holding arm 412 are arranged side by side in a vertical direction, in some possible embodiments, the clamping portion 521 includes a first limiting surface 5211, a second limiting surface 5212 and an abutting surface 5213, wherein the first limiting surface 5211 and the second limiting surface 5212 are parallel and are arranged at intervals in a vertical direction of the first display screen 100, and the abutting surface 5213 connects the first limiting surface 5211 and the second limiting surface 5212. Thus, the engaging portion 521 can form a groove extending along the horizontal direction, and the first limiting member 510 can extend into or out of the engaging portion 521 along the horizontal direction. And an opening formed by one ends of the first limiting surface 5211 and the second limiting surface 5212, which are away from the abutting surface 5213, can face upward in the vertical direction (as shown in fig. 11) or downward in the vertical direction (not shown).

The position limiting portion 511 is interposed between the first position limiting surface 5211 and the second position limiting surface 5212, and the abutting surface 5213 is recessed, so that the position limiting portion 511 abuts against the abutting surface 5213 to limit the position of the second display panel 200 in the horizontal direction.

That is, in the process that the limiting portion 511 extends into the engaging portion 521, the limiting portion 511 abuts against the abutting surface 5213, so that the second limiting member 520 and the first limiting member 510 can move relatively along the horizontal direction, that is, the second display panel 200 can move relatively along the horizontal direction relative to the first display panel 100, so as to adjust the gap between the first display panel 100 and the second display panel 200.

In some embodiments, the number of the limiting assemblies may be multiple, and the plurality of limiting assemblies are spaced at intervals along the vertical direction to improve the fixing stability of the second display screen 200.

To prevent the limiting portion 511 from being separated from the engaging portion 521, a connecting structure, such as a threaded fastener, may be disposed between the first limiting member 510 and the second limiting member 520. For convenience of operation, in some possible embodiments, the intelligent blackboard 10 further includes an elastic connection member 530, one end of the elastic connection member 530 is connected to the first limiting member 510, and the other end is connected to the second display 200, and the first limiting member 510 is configured to abut against the clamping portion 521 under the elastic force of the elastic connection member 530. That is, the first position-limiting member 510 is pressed against the abutting surface 5213 under the elastic force of the elastic connecting member 530, so as to prevent the position-limiting portion 511 from separating from the engaging portion 521.

The first limiting member 510 may be slidably connected to the second display screen 200, and at this time, an elastic connecting member 530 may be disposed at one end of the first limiting member 510 connected to the second display screen 200 and one end of the first limiting member 510 abutted to the second limiting member 520.

In order to simplify the structure, in some possible embodiments, the first limiting member 510 is rotatably connected to one of the first display screen 100 and the second display screen 200, a rotation axis of the first limiting member 510 is perpendicular to the second display screen 200, that is, the first limiting member 510 is rotatably connected to the second display screen 200, and a user can make the limiting portion 511 extend into or separate from the engaging portion 521 by driving the first limiting member 510 to rotate, which is convenient to operate.

In some embodiments, an operating portion (not shown) may be disposed on the first limiting member 510 for holding, and the operating portion is disposed at an end of the first limiting member 510 where the limiting portion 511 is disposed, so as to drive the first limiting member 510 to rotate.

It can be understood that the first limiting member 510 can maintain the extending state under the elastic force of the elastic connecting member 530, that is, even when the second display panel 200 is supported at the position to be installed in the inclined state, the first limiting member 510 extends to the side of the second display panel 200 under the elastic force of the elastic connecting member (as shown in fig. 12).

In some embodiments, when the user switches the second display screen 200 from the hanging state to the inclined state, the user may first apply a force in the horizontal direction and drive the second display screen 200 to move toward the side away from the first display screen 100 until the limiting portion 511 is separated from the clamping portion 521; then, the second display screen 200 is driven to rotate, so that the second display screen 200 is continuously driven to translate in the inclined state.

It can be understood that, when the user switches the second display screen 200 from the hanging state to the inclined state, the user may also first drive the first limiting member 510 to rotate, so that the limiting portion 511 is separated from the clamping portion 521, and at this time, the user may drive the second display screen 200 to rotate, so as to drive the second display screen 200 to translate in the inclined state.

The present embodiment does not limit the rotation stroke of the first limiting member 510. In some embodiments, the rotational stroke of the first limiting member 510 may be less than 360 °. Referring to fig. 13, a protruding limit stroke block is disposed on a rotating shaft of the first limiting member 510, an insertion groove is disposed on the first limiting member 510, the insertion groove is inserted into the rotating shaft of the first limiting member 510, a limit stroke groove matched with the limit stroke block is disposed on the insertion groove, and an extending angle of the limit stroke groove along the circumferential direction of the rotating shaft of the first limiting member 510 is less than 360 ° to limit a rotating stroke of the first limiting member 510.

It is understood that when the limiting portion 511 abuts against the abutting surface 5213, the limiting stroke block can be located at any position of the limiting stroke groove, for example, the limiting stroke block can abut against the end of the limiting stroke groove, so that the first limiting member 510 can extend into or extend into the clamping portion 521.
