Description

Display apparatus

Technical Field

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

Background

Because of the characteristics of multitasking, high operation efficiency, portability and the like, notebook computers have become an indispensable tool for modern people. A conventional notebook computer is configured with only a single display, and a multi-display design is proposed to meet the diversified demands of users. For the existing integrated design of multiple displays, the sub-displays are 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-displays can be accommodated in the back side or the inner accommodating 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 mother-son pictures.

However, the integrated design of the multi-display device cannot be disassembled freely, and has the disadvantage of being too heavy to be carried by a user.

Disclosure of Invention

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

According to an embodiment of the invention, a display device 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 arranged 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 concave for accommodating the pendulum bob clamping hook, and the pendulum bob clamping 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 convex part of the pendulum bob clamping hook is used for moving out of the concave part and clamping into the clamping groove or moving out of the clamping groove and moving back to the concave part.

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 by the cooperation of the positioning protrusion and the positioning groove, and prevent the second display from sliding off the first display relatively. On the other hand, after the positioning projection is inserted into the positioning groove, the second side edge of the second display body contacts the first side edge of the first display body. When the pendulum bob clamping hook is clamped into the clamping groove under the action of gravity, structural interference is generated between the clamping protrusion and the clamping groove, so that the second display is prevented from being separated from the first display, and the assembly reliability of the display equipment is improved. In contrast, when the pendulum bob clamping hook moves out of the clamping groove under the action of gravity, 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 assembly and the disassembly are extremely simple.

On the other hand, the first connector 112 may be a female connector, wherein the first connector 112 is disposed at the first side 111a and located between the two first magnets 113.

In particular, the number of the first magnets 113, the positioning grooves 111b and the clamping grooves 111c can be increased or decreased according to the actual requirement, and the invention is not limited.

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 bump 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 protrude from the second side 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 bump 124 and one pendulum hook 125 are set in a group, and form a second positioning group 1201. The number of the second magnets 123 may be two, and 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.

It is to be noted that the number of the second magnet 123, the positioning bump 124 and the pendulum hook 125 can be increased or decreased according to practical requirements, and the invention is not limited thereto.

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

As shown in fig. 1A and 1B, each positioning protrusion 124 may be smoothly inserted into the corresponding positioning groove 111B with each snap protrusion 125a being held 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 front view schematically showing a display device according to an embodiment of the present invention. Fig. 2B is an enlarged schematic cross-sectional view of fig. 2A along section line I-I. Fig. 3A is a schematic top view of the display device of fig. 2A. Fig. 3B is an enlarged schematic cross-sectional view of fig. 3A along section 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, the user can mount and position the second display 120 on one side of the first display 110 through 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 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 of the second magnets 123 and the corresponding first magnet 113 may provide a guiding and positioning mechanism to improve the convenience and reliability of installation. Similarly, each positioning projection 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 a 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 signal or power transmission.

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

Referring to fig. 1A, 1B and 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 from the first display surface 111 d. In detail, each of the clamping grooves 111c is located on the second inner wall surface 111f of the corresponding positioning groove 111b, that is, each of the clamping grooves 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 121a, and each positioning protrusion 124 has an opening 124b communicating with the recess 124a. In detail, each opening 124b is located on the motion path of the corresponding latch 125a and faces away from the second display surface 121b. Thus, the catch 125a of each pendulum catch 125 can move out of the recess 124a or back into the recess 124a via the corresponding opening 124b.

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

Further, as the inclination angle of the second display 120 in space changes, the position of the convex portion 125a of each pendulum hook 125 changes accordingly. 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 are tilted backward with respect to the gravitational direction 101. For example, the unfolding angle of the first display 110 may be 90 degrees or more. Under the action of gravity, the locking protrusion 125a of each pendulum hook 125 moves out of the recess 124a through the corresponding opening 124b and is locked into the corresponding locking groove 111c.

In the present embodiment, each pendulum hook 125 further has a pivot portion 125b pivotally connected to the positioning protrusion 124 and a weight portion 125c connected to the latch portion 125a, and the pivot portion 125b is far away from the latch portion 125a and the weight portion 125c. That is, the center of gravity of each pendulum hook 125 falls on the weight portion 125c and is close to the latch 125a. When the first display surface 111d and the second display surface 121b are parallel to the gravity direction 101 or recline with respect to the gravity direction 101, the weight portion 125c of each pendulum hook 125 drives 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 limiting portion 125d, wherein the limiting portion 125d is connected to the weight portion 125c, and the latch 125a and the weight portion 125c are located between the pivot portion 125B and the limiting portion 125 d. In addition, each positioning protrusion 124 has a stop portion 124c adjacent to the opening 124b, wherein a stop portion 125d of each pendulum hook 125 is located in the corresponding recess 124a and abuts against the stop portion 124c. Therefore, the stop 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 blocks of the pendulum hook 125 are accommodated in the recess 124a.

Fig. 4A is a front view schematically showing the display apparatus of fig. 2A when tilted forward. Fig. 4B is an enlarged schematic cross-sectional view of fig. 4A along section 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 gravitational direction 101 and are tilted forward relative to the gravitational direction 101. For example, the unfolding angle of the first display 110 may be 70 degrees or less. Under the action of gravity, the latch protrusion 125a of each pendulum latch 125 moves away from the corresponding latch slot 111c and moves back into the recess 124a via the corresponding opening 124b. At this time, the limiting portion 125d of each pendulum hook 125 is separated from the stopping portion 124c.

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

In summary, in the display device of the present invention, the user can mount and position the second display on one side of the first display by the cooperation of the positioning protrusion and the positioning groove and the cooperation of the second magnet and the first magnet, and prevent the second display from sliding off the first display relatively. On the other hand, after the positioning projection is inserted into the positioning groove, the second side edge of the second display body contacts the first side edge of the first display body. When the pendulum bob clamping hook is clamped into the clamping groove under the action of gravity, structural interference is generated between the clamping protrusion and the clamping groove, so that the second display is prevented from being separated from the first display, and the assembly reliability of the display equipment is improved. In contrast, when the pendulum bob clamping hook moves out of the clamping groove under the action of gravity, 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 assembly and the disassembly are extremely simple.

Finally, it should be noted that: the above embodiments are only for illustrating the technical solution of the present invention, and not for limiting the same; although the invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical scheme described in the foregoing embodiments can be modified or some or all of the technical features thereof can be replaced by equivalents; such modifications and substitutions do not depart from the spirit of the invention.
