Referring to fig. 1, fig. 2A, fig. 2B and fig. 3, fig. 1 is a schematic view of a display device according to the present invention; FIG. 2A is an enlarged schematic view of area A of FIG. 1; FIG. 2B is a cross-sectional view of FIG. 2A taken along line B-B'; fig. 3 is a partial plan view of the sliding part and the connecting part of the present invention after being engaged with the groove. The display device 1 of the present invention includes a display area 110, a frame 120, a key module 130, a bracket 20 and a base 30, wherein the frame 120 extends along a direction away from a user (a direction away from the display area 110) and is connected to a housing on the back of the display device, the frame 120 and the housing are rotatably pivoted to the bracket 20 as a whole, and the frame 120 and the bracket 20 are mounted on the base 30. The frame 120 surrounds the display area 110, and the groove 140 is disposed on the frame 120, such that the groove 140 is also located on the outer side of the display area 110, and the groove 140 extends continuously on at least two adjacent sides of the frame 120 (in the embodiment shown in the drawings, the groove 140 extends continuously on four sides of the frame 120). The key module 130 includes a module body 131 and a sliding part 132 connected to each other. The key module 130 further includes a plurality of keys (not shown in the drawings), which can be disposed on the module main body 131, and a user operating at least one of the keys can turn on an OSD menu of the display device or perform a first function, such as turning on or off a power supply of the display device. The key module 130 is slidably engaged with the groove 140 via the sliding portion 132. In the embodiment, the projection of the sliding portion 132 in the direction perpendicular to the groove 140 is a circle (which may be defined as a first circle), so that the key module 130 can slide around the display area 110 along the groove 140, thereby increasing the flexibility of the key module and facilitating the use of the user.
In an embodiment, as shown in fig. 2A and 2B, a surface of the bezel 120 facing the user is defined as a first surface S1, that is, the first surface S1 may be parallel or substantially parallel to a plane of the display area 110, at this time, the key module 130 is mounted on a front surface of the bezel 120, and the module main body 131 protrudes out of the first surface S1, so that there is no structural interference between the module main body 131 and the bezel 120 in the plane of the first surface S1, and the key module 130 can freely slide in two directions along any position of the groove 140 without being affected by the bezel.
In another embodiment, a side surface of the frame 120 perpendicular to the plane of the display area 110 is defined as the first surface S1, and at this time, the groove 132 may be disposed on the side surface, so that the key module 130 is mounted on the side surface of the frame 120. Similarly, the module body 131 protrudes from the first surface S1, and at this time, the module body 131 may be disposed parallel to the first surface S1 and corresponding to the side surface of the bezel 120, or the module body 131 may be disposed perpendicular to the first surface S1 and corresponding to the front surface of the bezel 120.
In an embodiment, two adjacent sides of the frame 120 are defined as a first side L1 and a second side L2, the first side L1 and the second side L2 are connected to a first corner D of the frame 120, the groove 140 extends continuously to the first side L1 and the second side L2, and the groove 140 has a first arc section at the first corner D, the groove through the arc section connects the linear grooves on the first side L1 and the second side L2 at the first corner D, and the projection of the sliding portion 132 on the groove 140 is circular, so that the key module 130 can slide between the first side L1 and the second side L2 more smoothly by sliding the first corner D. In practical application, the four frames of the display device 1 may be provided with linear grooves, and the grooves at the four corners connected to the four frames may be designed as circular arc sections, so as to facilitate the sliding of the key module 130.
In an embodiment, the sliding portion 132 of the key module 130 may be spherical, cylindrical, or ellipsoidal, so long as the projection of the sliding portion 132 perpendicular to the groove 140 is a circle. Through such a design, the sliding part 140 can smoothly slide in the groove 140 and slide from the groove 140 on one side to the groove 140 on the other side.
In practice, the projection of the sliding part 132 perpendicular to the groove 140 may have other shapes, not limited to the circular shape in the foregoing embodiments, and generally, the sliding part 132 is preferably designed to have a chamfered or arc shape at the edge, so that the sliding part 132 can slide smoothly in the groove 140 and slide from the groove 140 on one side to the groove 140 on the other side.
As shown in fig. 2B, the key module 130 further includes a connecting portion 133, the module body 131 and the sliding portion 132 are connected by the connecting portion 133, a projection of the connecting portion 133 on the recess 140 is also circular, and the connecting portion 133 may be spherical, cylindrical, or ellipsoidal. Since the projections of the sliding portion and the connecting portion perpendicular to the groove 140 are circular, and the centers of the two circles are generally coincident, the key module of the present invention can rotate around the connecting portion and the sliding portion, and specifically, the key module 130 can rotate around the rotation axis formed by the two centers of the circles. The rotation of the key module 130 can change the positions of the plurality of keys on the key module 130 along with the rotation of the key module 130, for example, the plurality of keys are arranged horizontally or vertically, so that the user can use the keyboard more conveniently, and the requirements of different users can be met, for example, the same use experience can be brought to the right-handed and left-handed users.
As shown in fig. 2B and 3, in the present embodiment, the connecting portion 133 has a cylindrical shape, so that the module body 131 is fixedly connected to the sliding portion 132 through the connecting portion 133. Since the relative positions of the module main body 131 and the sliding part 132 are fixed, when the groove 140 is located on the surface (i.e., the front surface) of the frame 120 facing the user, the plurality of keys on the module main body 131 face the user; when the groove 140 is located on a surface (i.e., a side surface) of the frame 120 perpendicular to the display area 110, a plane of the plurality of keys on the module main body 131 is also perpendicular to the display area 110. In practical applications, the connecting portion 133 is not limited thereto, such that the module body 131 can be pivotally connected to the sliding portion 132 through the connecting portion 133, and the relative position between the module body 131 and the sliding portion 132 can be adjusted. When the groove 140 is located on a surface (i.e., a side surface) of the bezel 120 perpendicular to the display area 110, the module body 131 may be oriented toward a user by pivoting with respect to the sliding portion 132 for convenient use.
In the embodiment, the shape of the groove 140 corresponds to the shapes of the sliding portion 132 and the connecting portion 133, and the projection of the sliding portion 132 on the groove 140 is defined as a first circle, and the projection of the connecting portion 133 on the groove 140 is defined as a second circle, in which the size of the second circle is smaller than that of the first circle, so that the sliding portion 132 and the connecting portion 133 are firmly engaged in the groove 140 without loosing.
In other embodiments, the projection of the sliding portion 132 perpendicular to the groove 140 may be a first shape with other shapes, the projection of the connecting portion 133 on the groove 140 is a second shape with other shapes, and the size of the second shape is smaller than the first shape, so that the sliding portion 132 and the connecting portion 133 can be engaged in the groove without being loosened; in addition, the first shape and the second shape do not need to correspond to each other, and may preferably have a chamfered or arc shape, so that the sliding portion 132 and the connecting portion 133 can smoothly slide in the groove 140 and slide from one side of the groove 140 to the other adjacent side. When the projection of the sliding portion 132 and the connecting portion 133 on the groove 140 is in other shapes, the size (and/or shape) of the connecting portion of the groove 140 on two adjacent sides of the frame 120 is set to enable the sliding portion 132 and the connecting portion 133 to slide through without falling off.
With reference to fig. 2A and fig. 2B, in the present invention, the module main body 131 is a rectangular parallelepiped structure, and after the key module 130 slides to a position desired by a user, since the projection of the sliding portion 132 on the groove 140 is circular, the key module 130 can be adjusted by rotating, so that the long edge of the module main body 131 is parallel to the boundary of the display area 110, by designing the distance between the groove 140 and the boundary of the display area 110 and designing the position of the sliding portion 132 on the module main body 131, the long edge of at least one key module main body 131 does not exceed the boundary of the display area 110 when the key module 130 rotates to the long edge of the module main body 131 is parallel to the boundary of the display area 110, and by rotating and adjusting, the boundary of the key module 130 does not block the display area 110, so that normal display of the display is not affected.
Referring to fig. 1, 4A and 4B, fig. 4A-4B are schematic diagrams illustrating a display device according to the present invention after rotation. The display device 1 of the present invention is a rotatable display apparatus, and fig. 1 shows an embodiment in which a first side L1 of a frame 120 of the display device is parallel to a base 30; fig. 4A and 4B illustrate an embodiment of the display device in which the second side L2 of the bezel 120 is parallel to the base 30.
In practical operation, when the image displayed in the display area 110 is a vertical image, the display device 1 of the present invention is controlled to rotate 90 degrees clockwise or counterclockwise around the joint between the bracket 20 and the housing for achieving a good viewing effect. In this embodiment, the display device 1 rotates clockwise by 90 degrees from the state of fig. 1 to the state of fig. 5A and 5B. At this time, the key module 130 slides along the groove 140 on the first side L1 to the first corner where the first side L1 is connected to the second side L2, and the user slides the key module 130 through the first corner where the first side L1 is connected to the second side L2, and moves the key module from any position of the first side L1 to any position of the second side L2. Therefore, any one of the four sides of the frame of the display device 1 is rotated to a position close to the base 30, and the key module 130 can slide to any position of the side.
Fig. 5A and 5B, and fig. 5A-5B are partial top views of a sliding portion and a groove in another embodiment of the present invention. Fig. 5A to 5B show the design of the sliding portion and the groove in another embodiment of the invention, in a specific embodiment, the sliding portion 132 of the invention includes a stopping structure 134, a plurality of engaging portions 141 corresponding to the stopping structure 134 are disposed at a plurality of predetermined positions of the groove 140, and after the key module 130 slides to one of the predetermined positions (e.g., defined as a first predetermined position), the module body 131 is rotated to allow the stopping structure 134 to be inserted into the engaging portion 141. The stopping structure 134 is perpendicular to the long side of the module body 131, so that the long side of the module body 131 is parallel to the side of the frame after the module body 131 is rotationally fixed at the first predetermined position, and further the long side of the module body 131 is parallel to the side of the current display area 110 close to the base, so that the display area is not blocked after the key module 130 is fixed.
In an embodiment, when the key module 130 slides in the groove 140, the key module 130 is rotated to make a connection line between a vertex of the triangular stopping structure 134 and a center of the sliding portion 132 parallel to a boundary of the groove 140, that is, the stopping structure 134 does not interfere with the groove 140 when the key module 130 slides, and the key module 130 can slide in the groove in two directions. When the key module 130 slides to the predetermined position, the triangular stopping structure 134 is engaged with the engaging portion 141 by rotating the key module 130, so that the key module 130 is fixed at the predetermined position. The key module 130 is fixed at the first predetermined position, which can prevent the key module 130 from rotating around the sliding portion 132 under the influence of its own weight, thereby blocking the display area 110. In the present embodiment, the stopping structure 134 is a triangular stopping structure, and the groove 140 is provided with a triangular engaging portion 141 corresponding to the stopping structure 134 at the first predetermined position, but in actual operation, the stopping structure 134 and the engaging portion 141 may also be selected from protrusions with other shapes and corresponding engaging portions, which is not limited in the present embodiment. The selection of the preset position in the invention can be selected according to the daily use habits of users, for example, the center of the side edge of the frame and the two ends of the side edge can be selected, and a plurality of positions can be selected as the preset positions at equal intervals on the side edge of the frame. In practical applications, the stopping structure 134 may also be disposed on the connecting portion 133, which is not limited in this example.
In practice, the key module 130 is light, in another embodiment, the friction between the sliding portion 132 and the groove 140 can be increased, and when the sliding portion 132 slides to the target position, the key module 130 can be fixed at the target position by the static friction between the sliding portion 132 (and the connecting portion 133) and the groove 140.
Referring to fig. 1, fig. 6A and fig. 6B, fig. 6A is an enlarged schematic view of a region a in another embodiment in fig. 1; fig. 6B is a cross-sectional view of fig. 6A taken along the dashed line B-B'. In this embodiment, the lower boundary of the key module 130 may exceed the lower boundary of the frame 120. The key module 130 is clamped in the groove 140 by the sliding portion 132 and the connecting portion 133, the sliding portion 132 and the connecting portion 133 are accommodated in the groove 140, and the module main body 131 completely protrudes out of the first surface S1 of the frame 120, i.e. the key main body 131 is not accommodated in the frame 120, so the size of the module main body 131 is not limited by the size of the display frame 120. When the key module 130 slides to the preset position and rotates until the long side of the module main body 131 is parallel to the boundary of the display area 110, the upper boundary of the key module 130 does not exceed the boundary of the display area 110, and the lower boundary of the key module 130 can exceed the lower boundary of the frame 120. Therefore, the size of the key module 130 does not affect the width of the frame 120, and the width of the frame 120 is not additionally increased, so that the key module 130 of the present invention can also be applied to a narrow-frame display.
In addition, the present invention further provides another display device (not shown), the display device has a display area, and the display device further includes a housing and a key module, the housing is disposed on the back of the display area, and a groove is disposed on the housing, the groove continuously extends to at least two adjacent side edges of the housing; the key module comprises a module main body and a sliding part which are connected, and the sliding part can be clamped in the groove in a sliding way. The arrangement of the elements can be as shown in fig. 1, and is not described in detail. In this embodiment, the groove and the key module are disposed on the housing at the back of the display area, that is, the groove and the key module are not disposed beside the display area but on the back of the display area, so that the display device can be applied to a frameless display device, and caters for the trend of frameless display devices.
In practical applications, the connection between the key module 130 and the display device 1 may be a conventional electrical connection, and the key module 130 and the display 10 may be electrically connected by disposing circuits in the sliding portion 132 and the groove 140. The connection mode between the key module 130 and the display device 1 can also be in a wireless connection mode, for example, in a wireless connection mode such as bluetooth, to wirelessly communicate with the display device and then control the display device.
In practical applications, the inside of the groove 140 may be provided with a movable shielding structure, so as to avoid entering of foreign matters into the groove 140 without hindering the sliding of the sliding portion 132, the shielding structure may be made of an insulating material, and the shielding structure may avoid entering of foreign matters into a short circuit condition when the key module 130 is electrically connected to the display 10.
In summary, in the display device of the invention, the groove continuously extending to the adjacent side edge is formed on the frame or the casing of the display, the key module is engaged in the groove through the sliding portion, and the key module can slide along the groove, so that the key module can slide to the adjacent side edge from one side edge in the rotatable display screen, thereby solving the problem that the user is inconvenient to operate the key on the key module after the rotatable display screen is rotated. Furthermore, because the projection of the sliding part on the groove can be provided with a chamfer or an arc (for example, the sliding part is circular), the key module protrudes out of the frame and can rotate around the sliding part, so that the key module can conveniently pass through the side joint of the frame, and the flexibility of the key module is further increased. The key module protrudes out of the surface of the frame facing a user or is arranged on the back of the display area, the size of the key module is not limited by the width of the frame, and the key module is suitable for narrow-frame or even frameless display devices.
The present invention is capable of other embodiments, and various changes and modifications can be made by one skilled in the art without departing from the spirit and scope of the invention.
