Referring to fig. 1 and 2, the present invention provides an intelligent display device (not shown) and a box 100 thereof. The smart display device includes a case 100.

The box 100 mainly plays a role of protection and support. The box 100 may be a hollow cubic structure, a spherical structure, a polygonal structure, a special-shaped structure, etc. according to the shape of the intelligent display device. In the present embodiment, the box 100 has a cubic structure. The intelligent display device further includes a display module (not shown) mounted on the box 100. The display module is mainly used for displaying electronic information. The display module comprises a display screen and panel glass, and the display module and the panel glass are stacked mutually.

It should be noted that the intelligent display device can be a display screen of a display stand, an electronic lamp post screen, an advertisement display screen, a traffic sign screen, and the like.

Referring to fig. 3, the box 100 of the preferred embodiment of the present invention includes a box body 110, a box door 120 and a locking structure 130.

Referring to fig. 4, the box body 110 is a hollow structure with an opening 111 at one end. Generally, the tank body 110 is made of a strong material such as stainless steel, alloy steel, aluminum, hard plastic, etc. so that the tank body 110 has a large bearing capacity. In the smart display device, when it is necessary to install or remove components into or from the housing 100 or to perform maintenance on the components in the housing 100, an operator may directly operate the smart display device inside the housing 100 through the opening 111.

One end of the door 120 is rotatably installed at an edge of the opening 111 to open or close the cabinet 100. Thus, the door 120 is closed or opened by being turned upside down. Specifically, the door 120 may be rotatably coupled to the cabinet body 110 by a hinge, a rotation shaft, or the like. Specifically, the door 120 is generally a sheet metal structure, and has high mechanical strength.

In this embodiment, the case 100 further includes a hinge (not shown). One end of the door 120 is rotatably coupled to the cabinet body 110 by a hinge. The hinge is a mechanical device used for connecting two solids and allowing relative rotation between the two solids, and can play a role in buffering in the closing process of the box door 120 and the box body 110, so that the noise generated by collision between the box door 120 and the box body 110 in the closing process is greatly reduced. Therefore, the hinge can make the opening and closing processes of the door 120 and the box body 110 more sensitive, and reduce the noise generated during the closing process.

Referring to fig. 5, in the present embodiment, the box 100 further includes a rotating shaft 140. The rotation shaft 140 is fixed at a position where the cabinet body 110 is rotatably coupled to the cabinet door 120. Specifically, a fixing screw hole 114 is formed at a position where the box body 110 is rotatably connected to the box door 120, and one end of the rotating shaft 140 is screwed into the fixing screw hole 114. The door 120 has a mounting hole 121 formed at a position opposite to the rotation shaft 140. The rotating shaft 140 is rotatably inserted into the mounting hole 121. Specifically, when the cabinet 100 is switched between the open state and the closed state, the door 120 rotates about the rotation shaft 140. Therefore, the arrangement of the rotating shaft 140 greatly reduces the probability of shaking and the like of the door 120 in the opening and closing processes, so that the operation precision of the door 120 in the opening and closing processes is higher.

In this embodiment, the box 100 further includes a limiting shaft 150 fixed to the edge of the opening 111. Specifically, the edge of the opening 111 of the box body 110 is provided with an installation screw hole 115, and one end of the limiting shaft 150 is screwed in the installation screw hole 115. The position of the door 120 opposite to the position-limiting shaft 150 is provided with a strip-shaped position-limiting hole 122 along the extending direction of the rotation track of the door 120. Specifically, the limiting hole 122 is a circular arc-shaped hole. The limiting shaft 150 is slidably disposed through the limiting hole 122. When the box body 100 is in an open state, the limiting shaft 150 is abutted against the inner wall of one end of the limiting hole 122; when the box 100 is in a closed state, the limit shaft 150 abuts against the inner wall of the other end of the limit hole 122.

Specifically, when the box body 100 is in the fully opened state, the limiting shaft 150 is located at one end of the limiting hole 122 close to the box body 110; when the box body 100 is in the closed state, the limiting shaft 150 is located at one end of the limiting hole 122 far away from the box body 110. Therefore, the limit shaft 150 is matched with the limit hole 122 to limit the door 120, so as to avoid the situation that the door 120 is excessively opened or the door 120 collides with the box body 110 due to excessive force applied by an operator in the process of opening and closing the door 120, so that the service life of the box body 100 can be effectively prolonged due to the arrangement of the limit shaft 150 and the limit hole 122.

The locking structure 130 is connected between the box body 110 and the box door 120, and the opening and locking between the box door 120 and the box body 110 can be realized by opening and closing the locking structure 130. In the using process, the locking structure 130 locks the box 100, so that the safety of the device of the intelligent display device and the safety of the parts in the box 100 can be increased.

Referring to fig. 6, the locking structure 130 includes a connecting arm 131 and a locking member 132. The connecting arm 131 is an elongated rod-like structure having opposite mounting and locking ends 1311, 1312. The mounting end 1311 is rotatably mounted to the door 120. The locking end 1312 is slidable on the tank body 110 along a predetermined trajectory. The locking end 1312 is formed with a locking slot 1313.

The predetermined track is a moving track of the locking end 1312 on the box body 110 during the opening or closing process of the box door 120. When the casing 100 has a cubic structure, the predetermined trajectory of the movement of the locking end 1312 on the casing body 110 is linear. Specifically, the connecting arm 131 may be a straight rod, a bent rod, or the like.

Referring to fig. 7, the locking member 132 is installed on the box 100 and located on a predetermined track. Therefore, when the locking end 1312 slides along the predetermined track on the box body 110, the locking end 1312 contacts the locking member 132 at a certain moment (in this embodiment, when the door 120 is closed). The locking member 132 includes a locking head 1321. The locking head 1321 may be a ball in the shape of a ball, a bump in the shape of a cube or cylinder, a needle bar, or the like. The locking head 1321 is retractable in a predetermined direction. Specifically, the predetermined direction is a direction perpendicular to the surface of the connection arm 131 where the locking groove 1313 is provided. When the case 100 is applied to an intelligent display device and is placed or installed on a horizontal plane, the preset direction is a vertical direction.

Referring to fig. 1 and 2 again, when the box 100 is switched between the open state and the closed state, the box door 120 drives the connecting arm 131 to rotate around the mounting end 1311, so as to drive the locking end 1312 to slide on the box body 110 along a predetermined track until the locking head 1321 is engaged with or disengaged from the locking groove 1313.

Specifically, the locking head 1321 is retracted in a direction away from the locking end 1312 to facilitate the locking head 1321 to slide into or out of the locking slot 1313; the locking head 1321 protrudes in a direction toward the locking end 1312 so that the locking head 1321 is engaged in the locking groove 1313 or disengaged from the locking groove 1313. When the box 100 is in a closed state, the lock head 1321 is engaged with the locking groove 1313, and at this time, the locking structure 130 realizes a locking function, so that the box 100 is in a locked state; when the cabinet 100 is in the open state, the locking head 1321 is separated from the locking groove 1313, and the locking structure 130 performs an unlocking function, so that the cabinet 100 is in the open state.

The locking process of the box 100 is: firstly, the door 120 is rotated in a direction approaching the opening 111 relative to the box body 110 under the action of an external force, and meanwhile, the connecting arm 131 is driven by the door 120 to rotate around the mounting end 1311 and drive the locking end 1312 to slide along a preset track in a direction pointing to the locking member 132 until the locking head 1321 extends and contracts along a preset direction, so that the locking head 1321 is engaged in the locking groove 1313 to complete the locking operation of the box body 100.

The opening process of the box 100 is: firstly, the door 120 is rotated relative to the box body 110 in a direction away from the opening 111 under the action of external force, meanwhile, the connecting arm 131 is driven by the door 120 to rotate around the mounting end 1311 and drive the locking end 1312 to slide in a direction away from the locking member 132 until the locking head 1321 extends and contracts in a preset direction, so that the locking head 1321 is separated from the locking groove 1313 to realize the opening operation of the locking structure 130, and then the door 120 is continuously rotated relative to the box body 110 in a direction away from the opening 111 under the action of external force until the door 120 is opened to a preset position or completely opened to finish the opening operation of the box body 100. Here, the preset position refers to any position between a position when the casing 100 is fully opened and a position when the casing 100 is closed.

Therefore, the locking and unlocking functions of the locking structure 130 are realized by the engagement of the connecting arm 131 and the locking member 132, i.e., the engagement and disengagement of the locking head 1321 and the locking groove 1313. Therefore, the locking structure 130 is provided, so that an operator can open and close the box 100 without additionally performing the operation of locking devices such as opening and locking, and the like, thereby greatly simplifying the operation of opening and locking the box 100, and facilitating the operation.

Moreover, the locking structure 130 is usually disposed in a less conspicuous position such as the inside and the bottom of the box 100, so as to avoid a more complicated visual experience of the appearance brought to people, and make the appearance of the box 100 more neat and beautiful. Specifically in this embodiment, the locking structure 130 is disposed inside the box 100, so that the locking structure 130 is protected, the service life of the locking structure 130 is effectively prolonged, the appearance of the box 100 is tidy and beautiful, and better visual experience is brought to people.

Specifically, when the box 100 is switched from the open state to the closed state, the connecting arm 131 drives the locking end 1312 to slide in a direction pointing to the locking member 132 until the locking slot 1313 is engaged with the locking head 1321, so as to lock the box door 120 and the box body 110; when the box 100 is switched from the closed state to the open state, the door 120

In this embodiment, the locking head 1321 is a ball. As the name implies, the balls also have a rolling action during movement. Therefore, the sliding of the locking head 1321 into and out of the locking groove 1313 is the rolling of the locking head 1321 into and out of the locking groove 1313. Therefore, the locking head 1321 is provided with a ball, so that the locking head 1321 can slide into and out of the locking groove 1313 more smoothly, and the opening and locking processes of the box 100 are more sensitive.

The locking groove 1313 is a spherical groove. Since the inner wall of the spherical groove is smooth, the locking groove 1313 is configured as a spherical groove, so that the lock 1321 slides into and out of the locking groove 1313 more smoothly, and the operation sensitivity of the box 100 in the opening and locking processes is further improved.

Further, in the present embodiment, the locking member 132 is a wave ball screw. The box body 110 is provided with a threaded hole 112, and the wave ball screw is screwed in the threaded hole 112. Specifically, the wave ball screw comprises a shell, a spring accommodated and installed in the shell, and a ball which is installed at one end of the spring in a rolling manner and partially extends out of the shell. Wherein the ball is a tapered end 1321. Since the wave ball screw is a standard component and has a low processing cost, the locking member 132 is configured as the wave ball screw, which can effectively reduce the processing cost of the box 100.

Moreover, the wave ball screw is screwed in the threaded hole 112, so that the locking member 132 can be detachably mounted, and the locking member 132 can be more conveniently disassembled and assembled.

Referring to fig. 1, fig. 2 and fig. 6 again, in the present embodiment, a locking portion 1314 is disposed on a side of the locking end 1312 facing the box body 110. The lock 1314 is protrudingly provided in a direction toward the case body 110. The end surface of the lock 1314 facing the end of the case body 110 is recessed to form a lock groove 1313. Therefore, when the locking end 1312 slides on the box body 110 along the preset track, only the end surface of the locking portion 1314 contacts with the surface of the box body 110, so that the contact area between the connecting arm 131 and the box body 110 when the locking end 1312 slides on the box body 110 is greatly reduced, and the friction force applied to the connecting arm 131 in the opening and closing processes of the box door 120 is reduced, so that the opening and closing actions of the box door 120 are more labor-saving and smooth, and the convenience in the operation of the opening and locking processes of the box door 120 is further improved.

Further, in the present embodiment, the side of the locking end 1312 where the lock 1314 is located is provided with a guide post 1315. The guide posts 1315 are located between the mounting end 1311 and the locking portion 1314. The box body 110 is provided with a strip-shaped through hole 113 along the extending direction of the preset track at a position opposite to the guide column 1315. The guide post 1315 is slidably inserted into the elongated through hole 113.

Thus, when the box 100 is switched between the open state and the closed state, the guide pillar 1315 slides in the elongated through hole 113 along a predetermined trajectory to guide the locking end 1312. Therefore, the guide posts 1315 and the elongated through holes 113 are disposed, so that the sliding accuracy of the locking end 1312 along the predetermined track is higher, and the running accuracy of the door 120 during opening and closing is effectively improved.

Further, in this embodiment, the box 100 further includes a limit fastener (not shown). The ends of the guide posts 1315 pass through the elongated through holes 113 and are removably connected to the retaining fasteners, which are slidable along a predetermined path. Specifically, the limit fastener includes a threaded fastener screwed to the end of the guide post 1315 and a washer clamped between the threaded fastener and the end face of the end of the guide post 1315. Wherein, the threaded fastener is a bolt, a screw and the like.

Therefore, the limiting fastener mainly plays a role in axial limiting for the guide column 1315, the situation that the guide column 1315 is separated from the long strip-shaped through hole 113 in the using process is avoided, and the using reliability of the box body 100 is greatly improved. And set up spacing fastener and guide post 1315 into the mode of dismantling the connection for the dismouting of linking arm 131 is more convenient. Therefore, even if the connecting arm 131 and other parts are damaged during use, the limit fastener is detachably connected to the guide post 1315, so that the replacement and maintenance of the case 100 are more convenient.

In this embodiment, the mounting end 1311 is provided with a mounting shaft 1316. The door 120 has a connecting hole 123 formed at a position opposite to the mounting shaft 1316, and the mounting shaft 1316 is rotatably inserted into the connecting hole 123.

Therefore, when the connecting arm 131 is required to be installed on the door 120, the mounting shaft 1316 only needs to be inserted into the connecting hole 123, and the mounting shaft 1316 can rotate relative to the connecting hole 123, so that the mounting shaft 1316 and the connecting hole are arranged, and the connecting arm 131 can be installed on the door 120 more conveniently. Moreover, when the connecting arm 131 is driven by the door 120 to rotate around the mounting end 1311, the connecting arm 131 rotates around the mounting shaft 1316, so that the rotating operation precision of the connecting arm 131 is greatly improved, and the operation precision of the door 120 in the opening and closing processes of the box body 100 is effectively improved. In order to improve the rotation accuracy of the mounting shaft 1316, the mounting shaft 1316 is generally a cylindrical shaft, and the connecting hole 123 is a circular hole.

In the above-mentioned intelligent display device and the box 100 thereof, during the opening and closing process of the box 100, the locking member 132 extends and retracts along the axial direction, so that the locking groove 1313 is engaged with or separated from the locking head 1321, thereby realizing the locking or opening action of the locking structure 130. During the closing process of the container 100, the door 120 rotates in a direction toward the opening 111 of the container body 110, and the locking end 1312 slides in a direction toward the locking member 132 under the driving of the door 120 until the locking groove 1313 engages with the locking head 1321 to complete the locking of the container 100; during the opening of the container 100, the door 120 is rotated in a direction away from the opening 111 of the container body 110, and the locking end 1312 slides in a direction away from the locking member 132 under the driving of the door 120 until the locking groove 1313 is separated from the locking head 1321, so as to complete the opening of the container 100. Therefore, the locking structure 130 is configured to realize the opening and locking of the box 100 without an operator performing additional operations of the locking devices such as opening and locking, thereby greatly simplifying the opening and locking operations of the box 100 and facilitating the operation.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.
