Description

Display device

Technical Field

The present invention relates to a display device, and more particularly, to a display device including at least two displays.

Background

Because the notebook computer has the characteristics of multitasking, high operation efficiency, portability and the like, the notebook computer becomes an indispensable tool for modern people. In order to meet the diversified demands of users, a multi-display design is proposed. In the conventional multi-display integrated design, the sub-display is connected to the main display by a pivoting mechanism, a sliding mechanism or a combination of the above mechanisms, and in one of the operation modes, the sub-display can be received in the back side or the internal receiving space of the main display; in another operation mode, the sub-display can move relative to the main display and move to the side of the main display, so as to achieve the purpose of expanding the screen size or displaying the main and sub-pictures.

However, the integrated design of the multi-display cannot be freely disassembled and assembled by the user, and has the disadvantage of being too thick and inconvenient for the user to carry.

Disclosure of Invention

The present invention is directed to a display device which has excellent reliability and is easy to disassemble and assemble.

According to an embodiment of the present invention, a display apparatus includes a first display and a second display. The first display comprises a first display body, and the first display body is provided with a first side edge, a positioning groove positioned on the first side edge and a clamping groove positioned in the positioning groove. The second display is detachably mounted on one side of the first display body, wherein the second display comprises a second display body, a positioning lug and a pendulum hook, and the second display body is provided with a second side edge. The positioning lug is connected with the second side edge, wherein the positioning lug is provided with a recess for accommodating the pendulum hook, and the pendulum hook is pivoted on the positioning lug. The pendulum hook is provided with a clamping protrusion. The positioning lug is inserted into the positioning groove, and the second side edge of the second display body is contacted with the first side edge of the first display body. The clamping protrusion of the pendulum hook is used for moving out of the recess and clamping into the clamping groove or moving away from the clamping groove and moving back to the recess.

Based on the above, in the display device of the present invention, the user can mount and position the second display on one side of the first display through the cooperation of the positioning protrusion and the positioning groove, and prevent the second display from slipping off relative to the first display. On the other hand, after the positioning protrusion is inserted into the positioning groove, the second side of the second display body contacts the first side of the first display body. When the pendulum hook is clamped into the clamping groove under the action of gravity, the clamping protrusion and the clamping groove generate structural interference, so that the second display is prevented from being separated from the first display, and the assembling reliability of the display device is improved. On the contrary, when the hook of the pendulum bob is under the action of gravity to move the clamping protrusion out of the clamping groove, the structural interference between the clamping protrusion and the clamping groove is eliminated, so that a user can detach the second display from the first display, and the detachment is very easy.

The number of the first magnets 113 may be two, and the first magnets are located between the two positioning grooves 111 b. On the other hand, the first connector 112 may be a female connector, wherein the first connector 112 is disposed on the first side 111a and located between the two first magnets 113.

It should be noted that the number of the first magnets 113, the positioning grooves 111b and the slots 111c can be increased or decreased according to actual requirements, and the invention is not limited thereto.

As shown in fig. 1B, the second display 120 includes a second display body 121, a second connector 122, a second magnet 123, a positioning protrusion 124 and a pendulum hook 125, wherein the second display body 121 has a second side 121a corresponding to the first side 111a, and the second magnet 123 is disposed in the second display body 121 corresponding to the second side 121 a. The positioning protrusions 124 are connected to or protruded from the second side edge 121a, wherein the number of the positioning protrusions 124 may be two, and each positioning protrusion 124 is correspondingly provided with a pendulum hook 125. That is, each positioning lug 124 is arranged in a group with one pendulum hook 125, and constitutes the second positioning group 1201. The number of the second magnets 123 may be two, and the second magnets are located between the two positioning protrusions 124. On the other hand, the second connector 122 may be a male connector, wherein the second connector 122 is disposed on the second side 121a and located between the two second magnets 123.

Specifically, the number of the second magnets 123, the positioning protrusions 124 and the pendulum hooks 125 can be increased or decreased according to actual requirements, and the invention is not limited thereto.

As shown in fig. 1B, each positioning protrusion 124 has a recess 124a for accommodating a pendulum hook 125, and the pendulum hook 125 is pivotally connected to the positioning protrusion 124 to rotate (or swing) relative to the positioning protrusion 124 under the action of gravity. As shown in fig. 1A and 1B, each second positioning set 1201 is disposed corresponding to and matches one first positioning set 1101. In detail, each pendulum hook 125 has a catching protrusion 125a that mates with the corresponding catching groove 111c, and each catching protrusion 125a is held in the corresponding recess 124a in the state shown in fig. 1B.

As shown in fig. 1A and 1B, each positioning protrusion 124 can be smoothly inserted into the corresponding positioning groove 111B with each locking protrusion 125a retained in the corresponding recess 124a, so as to mount the second display 120 on one side of the first display 110.

Fig. 2A is a schematic front view of a display device according to an embodiment of the invention. Fig. 2B is an enlarged schematic cross-sectional view taken along the sectional line I-I in fig. 2A. Fig. 3A is a schematic top view of the display device of fig. 2A. Fig. 3B is an enlarged sectional view of fig. 3A taken along the sectional line J-J. Referring to fig. 2A and 3A, when the second display 120 is mounted on one side of the first display 110, the second side 121a of the second display body 121 contacts the first side 111a of the first display body 111.

Referring to fig. 2B and 3B, a user can mount and position the second display 120 on one side of the first display 110 by the cooperation of each second magnet 123 and the corresponding first magnet 113 and the cooperation of each positioning protrusion 124 and the corresponding positioning groove 111B, and the second display 120 and the first display 110 are not easy to slip off relatively based on the magnetic attraction between each second magnet 123 and the corresponding first magnet 113 and the structural interference between each positioning protrusion 124 and the corresponding positioning groove 111B. That is, each second magnet 123 and the corresponding first magnet 113 can provide a guiding and positioning mechanism to improve the installation convenience and reliability. Similarly, each positioning protrusion 124 and the corresponding positioning groove 111b can provide a guiding and positioning mechanism to improve the installation convenience and reliability.

As shown in fig. 3B, each positioning protrusion 124 is inserted into the corresponding positioning groove 111B, and the second side 121a of the second display body 121 contacts the first side 111a of the first display body 111. In addition, the second connector 122 is connected to and contacts the first connector 112, so that the second display 120 is electrically coupled to the first display 110 for transmitting signals or power.

Referring to fig. 2B, the locking protrusion 125a of each pendulum locking hook 125 moves out of the corresponding recess 124a and is locked into the corresponding locking slot 111c to generate structural interference, thereby preventing the second display 120 from being separated from the first display 110 and improving the assembling reliability of the display apparatus 100.

Referring to fig. 1A, fig. 1B and fig. 2B, in the present embodiment, the first display body 111 further has a first display surface 111d connected to the first side 111A, and each positioning groove 111B has a first inner wall surface 111e close to the first display surface 111d and a second inner wall surface 111f far away from the first display surface 111 d. In detail, each of the locking slots 111c is located on the second inner wall surface 111f of the corresponding positioning groove 111b, that is, each of the locking slots 111c is located on a side of the corresponding positioning groove 111b relatively far from the first display surface 111 d.

The second display body 121 further has a second display surface 121b connected to the second side edge 121a, and each positioning protrusion 124 has an opening 124b communicated with the recess 124 a. In detail, each opening 124b is located on an action path of the corresponding snap projection 125a and faces away from the second display surface 121 b. Thus, the catching protrusion 125a of each pendulum catch 125 may move out of the recess 124a or back into the recess 124a via the corresponding opening 124 b.

Referring to fig. 2A and 2B, the first display surface 111d is adjacent to the second display surface 121B and faces the same direction of the space. When each positioning protrusion 124 is inserted into the corresponding positioning groove 111b, each opening 124b is aligned with the corresponding slot 111c, and each pendulum hook 125 rotates (or swings) relative to the positioning protrusion 124 under the action of gravity, so that each hook 125a moves out of the recess 124a through the corresponding opening 124b and is caught in the corresponding slot 111 c.

Further, as the tilt angle of the second display 120 in space changes, the position of the catching protrusion 125a of each pendulum catching hook 125 changes. In the state shown in fig. 2A and 2B, the first display surface 111d and the second display surface 121B are parallel to the gravitational direction 101 or inclined backward with respect to the gravitational direction 101. Taking a notebook computer as an example, the unfolding angle of the first display 110 may be greater than or equal to 90 degrees. Under the action of gravity, the catching protrusion 125a of each pendulum catch 125 moves out of the recess 124a via the corresponding opening 124b and catches in the corresponding catching groove 111 c.

In this embodiment, each pendulum hook 125 further has a pivot portion 125b pivotally connected to the positioning protrusion 124 and a weight portion 125c connecting the locking protrusion 125a, and the pivot portion 125b is far away from the locking protrusion 125a and the weight portion 125 c. That is, the center of gravity of each pendulum hook 125 falls on the weight portion 125c and is close to the catching protrusion 125 a. When the first display surface 111d and the second display surface 121b are parallel to the gravity direction 101 or tilted backward relative to the gravity direction 101, the weight portion 125c of each pendulum hook 125 can drive the protrusion 125a to move out of the recess 124a through the corresponding opening 124b under the action of gravity.

As shown in fig. 2B, each pendulum hook 125 further has a position-limiting portion 125d, wherein the position-limiting portion 125d is connected to the weight portion 125c, and the locking protrusion 125a and the weight portion 125c are located between the pivoting portion 125B and the position-limiting portion 125 d. In addition, each positioning protrusion 124 has a stopping portion 124c adjacent to the opening 124b, wherein the limiting portion 125d of each pendulum hook 125 is located in the corresponding recess 124a and abuts against the stopping portion 124 c. Therefore, the stopping portion 124c of each positioning protrusion 124 can be used to determine the rotation (or swing) range of the corresponding pendulum hook 125, and ensure that most of the block of the pendulum hook 125 is accommodated in the recess 124 a.

Fig. 4A is a schematic front view of the display apparatus of fig. 2A tilted forward. Fig. 4B is an enlarged sectional view of fig. 4A taken along the sectional line K-K. Referring to fig. 4A and 4B, the first display surface 111d and the second display surface 121B are not parallel to the gravity direction 101 and are tilted forward relative to the gravity direction 101. Taking a notebook computer as an example, the unfolding angle of the first display 110 may be less than or equal to 70 degrees. Under the action of gravity, the catch 125a of each pendulum catch 125 moves away from the corresponding catch slot 111c and moves back into the recess 124a via the corresponding opening 124 b. At this time, the limiting portion 125d of each pendulum hook 125 is separated from the stopping portion 124 c.

After the structural interference between the protrusion 125a of each pendulum hook 125 and the corresponding slot 111c is eliminated, the user can detach the second display 120 from the first display 110, so the detachment is very easy.

In summary, in the display apparatus of the present invention, the user can mount and position the second display on one side of the first display through the cooperation between the positioning protrusion and the positioning groove and the cooperation between the second magnet and the first magnet, and prevent the second display from slipping off from the first display. On the other hand, after the positioning protrusion is inserted into the positioning groove, the second side of the second display body contacts the first side of the first display body. When the pendulum hook is clamped into the clamping groove under the action of gravity, the clamping protrusion and the clamping groove generate structural interference, so that the second display is prevented from being separated from the first display, and the assembling reliability of the display device is improved. On the contrary, when the hook of the pendulum bob is under the action of gravity to move the clamping protrusion out of the clamping groove, the structural interference between the clamping protrusion and the clamping groove is eliminated, so that a user can detach the second display from the first display, and the detachment is very easy.

Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; while the invention has been described in detail and with reference to the foregoing embodiments, it will be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; and the modifications or the substitutions do not make the essence of the corresponding technical solutions depart from the scope of the technical solutions of the embodiments of the present invention.
