[0031] In order to provide a further understanding of the purpose, structure, features, and functions of the present invention, the following detailed description is given in conjunction with the embodiments.
[0032] Certain words are used in the specification and claims to refer to specific components. Those with ordinary knowledge in the field should understand that manufacturers may use different terms to refer to the same component. This specification and claims do not use differences in names as a way to distinguish components, but rather use differences in components' functions as the criteria for distinction. The term "including" mentioned throughout the specification and claims is an open-ended term and should be interpreted as "including but not limited to".
[0033] The display screen bracket 1 provided by the present invention is shown in FIG. Figures 1 to 3 and Figure 8 , including a bracket body 11 and a projection module 12. The bracket body 11 is used to carry the display screen 2, and the display screen 2 is used to display the main picture. The bracket body 11 includes a housing cavity 110, and the housing cavity 110 has an opening. The projection module 12 is coupled to the bracket body 11, and the projection module 12 includes a pixel array and a light source, wherein the pixel array can be any element having a color display function, such as including liquid crystal; the light source can be any device having a light-emitting function. The projection module 12 is used to project a projection picture different from the main picture displayed on the display screen 2 in a first direction P. For example, the projection picture can be a pattern of a brand LOGO, or a custom graphic set by a user, or parameter information in the display screen 2 or the connected computer host 5, such as the occupancy rate and temperature of the central processing unit (CPU) and the graphics processing unit (GPU).
[0034] The projection module 12 is selectively located at the storage position or the projection position. When the projection module 12 is located at the storage position, Figure 5 As shown, the projection module 12 is received in the accommodating cavity 110, and the outer surface of the shell 122 of the projection module 12 is substantially flush with the outer surface of the bracket body 11 near the opening of the accommodating cavity 110. At this time, the first direction P′ is toward the inner side of the accommodating cavity 110, and the projection module 12 does not project an image. For example, when the projection module 12 is rotated to a specific angle / position toward the storage position, the projection module 12 automatically turns off the projected image; or, the user can manually turn on or off the projected image of the projection module 12, and the present invention is not limited thereto; when the projection module 12 is located at the projection position, as shown in FIG. Figure 4As shown, at least a portion of the projection module 12 protrudes from the opening outside the accommodating cavity 110, and the first direction P is toward the outside of the accommodating cavity 110, and the projection module 12 projects the projection picture to the outside of the accommodating cavity 110. In other words, when the user needs to watch the projection picture, the projection module 12 can be switched to the projection position, and the projection module 12 projects the projection picture toward the projection surface (such as a desktop, a wall, etc.) located in the first direction P, so that there is a certain distance between the projection picture and the main picture displayed on the display screen 2. When the user needs to concentrate on watching the main picture, the projection picture is not easy to enter the user's field of view, so it is not easy to distract the user.
[0035] In a preferred embodiment, Figure 4 and Figure 6 As shown, when the projection module 12 is located at the projection position, the first direction P is toward the plane where the bracket body 11 is placed, that is, at this time, the projection module 12 projects the projection picture onto the plane where the bracket body 11 is placed. For example, when a user uses the display device, the bracket body 11 is placed on the desktop, and the first direction P is toward the position between the display screen bracket 1 and the user, so that the projection picture is projected on the desktop at this position, thereby achieving the effect of decorating the display device with a personalized pattern.
[0036] In a preferred embodiment, Figure 4 and Figure 5 As shown, the projection module 12 is rotatably connected to the inner wall of the accommodating chamber 110, and the projection module 12 is rotated relative to the inner wall of the accommodating chamber 110 to switch between the storage position and the projection position. That is, when the user needs to watch the projected image, the user can hold the projection module 12 located at the opening of the accommodating chamber 110 and rotate it toward the outside of the accommodating chamber 110, so that at least part of the projection module 12 protrudes from the opening of the accommodating chamber 110; when the user wants to close the projected image, the projection module 12 can be rotated toward the inside of the accommodating chamber 110 to store the projection module 12 in the accommodating chamber 110. Preferably, as Figure 4 As shown, the first inner wall and the second inner wall of the accommodating cavity 110 are respectively provided with a first slide groove 1101 and a second slide groove 1102, and the projection module 12 is respectively fixedly connected with a first stopper 123 and a second stopper 124. The first stopper 123 and the second stopper 124 are respectively slidably connected to the first slide groove 1101 and the second slide groove 1102 ( Figure 4Only the first slide groove 1101 and the first stopper 123 are shown in the figure, and the second slide groove 1102 and the second stopper 124 are located opposite to them and are omitted in the figure). For example, the first slide groove 1101 and the second slide groove 1102 are arc-shaped, so that when the projection module 12 rotates relative to the first inner wall and the second inner wall of the accommodating chamber 110, the first stopper 123 and the second stopper 124 slide in the first slide groove 1101 and the second slide groove 1102 in corresponding directions respectively. Specifically, the first slide groove 1101 has a first end and a second end opposite to each other, and the second slide groove 1102 has a first end and a second end opposite to each other, such as Figure 4 and Figure 5 As shown, when the projection module 12 is located at the storage position, the first stopper 123 is located at the second end of the first slide groove 1101, and the second stopper 124 is located at the second end of the second slide groove 1102; when the projection module 12 is switched from the storage position to the projection position, the first stopper 123 slides toward the first end of the first slide groove 1101, and the second stopper 124 slides toward the first end of the second slide groove 1102. In this way, when the projection module 12 is switched between the storage position and the projection position, its actuation process is more stable.
[0037] Preferably, the first end of the first slide groove 1101 further extends and communicates with the first end groove 1103, and the first end of the second slide groove 1102 further extends and communicates with the second end groove 1104 ( Figure 4 Only the first end groove 1103 is shown, and the second end groove 1104 is located opposite to it and has been omitted in the figure). After the first limit member 123 and the second limit member 124 slide to the first end of the first slide groove 1101 and the first end of the second slide groove 1102 respectively, the first limit member 123 and the second limit member 124 can be further moved into the first end groove 1103 and the second end groove 1104 respectively. By sliding the first limit member 123 and the second limit member 124 in the first end groove 1103 and the second end groove 1104 respectively, the projection distance between the projection module 12 and the projection surface can be adjusted to obtain a better projection effect. For example, if Figure 4 As shown, the first end groove 1103 and the second end groove 1104 extend along the vertical direction Z, that is, when the first stopper 123 and the second stopper 124 slide in the first end groove 1103 and the second end groove 1104 respectively, the height of the projection module 12 relative to the plane on which the bracket body 11 is placed can be adjusted, thereby adjusting the projection distance. In order to ensure that the rotational connection structure between the projection module 12 and the inner wall of the accommodating chamber 110 can cooperate with the above-mentioned actuation process of the first stopper 123 and the second stopper 124, the first inner wall of the accommodating chamber 110 is further provided with a first axial hole 1105, and the second inner wall is further provided with a second axial hole 1106. The projection module 12 is rotationally connected to the first axial hole 1105 and the second axial hole 1106 respectively through a pivot, wherein, as shown in FIG. Figures 2 to 4As shown, the pivot includes a pivot body 125, a third limiting member 126 and a fourth limiting member 127, the pivot body 125 is respectively penetrated in the first shaft hole 1105 and the second shaft hole 1106, and then the third limiting member 126 and the fourth limiting member 127 are respectively installed on the two ends of the pivot body 125, so that the two ends of the pivot are respectively limited in the first shaft hole 1105 and the second shaft hole 1106; wherein, the pivot body 125 can axially rotate in the first shaft hole 1105 and the second shaft hole 1106, and the extension directions of the first shaft hole 1105 and the second shaft hole 1106 are respectively the same as the extension directions of the first end groove 1103 and the second end groove 1104, so that the pivot body 125 can slide along the extension direction of the first shaft hole 1105 / the second shaft hole 1106. For example, the first shaft hole 1105 and the second shaft hole 1106 are elliptical, that is, the extension direction of the first shaft hole 1105 and the second shaft hole 1106 is the long axis direction of the ellipse; the first shaft hole 1105 and the second shaft hole 1106 can also be rectangular or other shapes, and the present invention is not limited thereto. Figure 4 Taking the first limit member 123, the first slide groove 1101, the first end groove 1103 and the first axial hole 1105 as an example, when the first limit member 123 is located in the first slide groove 1101, the pivot is located at the lower end of the first axial hole 1105, and the first slide groove 1101 is an arc-shaped slide groove with the axial position of the pivot at this time as the center of the circle. When the projection module 12 is converted between the storage position and the projection position, the pivot rotates in the first axial hole 1105, and the first limit member 123 slides correspondingly in the first slide groove 1101; when the first limit member 123 slides in the first end groove 1103, the pivot slides correspondingly in the first axial hole 1105, and when the first limit member 123 slides to the uppermost end of the first end groove 1103, the pivot is at the uppermost end of the first axial hole 1105.
[0038] In a preferred embodiment, one of the magnetic member 120 or the magnet 111 is installed in the accommodating cavity 110, and the other of the magnetic member 120 or the magnet 111 is installed on the projection module 12, wherein the magnetic member 120 is made of a magnetically attractable material such as an iron sheet. In this embodiment, the magnet 111 is installed on the third inner wall of the accommodating cavity 110, and the magnetic member 120 is installed on the projection module 12. Figure 6 and Figure 7As shown, when the projection module 12 is located at the projection position, the magnetic member 120 corresponds to the position of the magnet 111, and under the action of the magnetic attraction force between the magnet 111 and the magnetic member 120, the projection module 12 is magnetically connected to the third inner wall of the accommodating cavity 110 to fix the projection module 12 at the projection position. For example, the magnetic member 120 installed on the projection module 12 is relatively large and consistent with the extension direction of the first end groove 1103 and the second end groove 1104, while the magnet 111 installed in the accommodating cavity 110 is relatively small; or, the magnet 111 installed in the accommodating cavity 110 is relatively large and consistent with the extension direction of the first end groove 1103 and the second end groove 1104, while the magnetic member 120 installed on the projection module 12 is relatively small, and the present invention is not limited thereto. At this time, when the first limit member 123 and the second limit member 124 slide to any position in the first end groove 1103 and the second end groove 1104 respectively as described above, a magnetic attraction force is generated between the magnetic attraction member 120 and the magnet 111 to fix the projection module 12 at a position corresponding to the projection distance.
[0039] In a preferred embodiment, Figure 7As shown, the projection module 12 includes a projection unit 121 and a housing 122. The projection unit 121 is respectively fixedly connected with at least one first fixed end 1211 and at least one second fixed end 1212. The first fixed end 1211 and the second fixed end 1212 both have through holes. The housing 122 includes a first boss and a second boss disposed on the inner surface of the housing 122. The first boss and the second boss both have threaded holes. At least one first screw 31 and at least one second screw 32 respectively pass through the through holes of the first fixed end 1211 and the second fixed end 1212 in a direction opposite to the first direction P and are locked in the first boss and the second boss of the housing 122, so that the projection unit 121 is fixedly connected with the housing 122. The first fixed end 1211 and the second fixed end 1212 are arranged along the second direction I, and the second direction I is substantially perpendicular to the first direction P. It should be noted that the locking direction being approximately opposite to the first direction P can also be considered as the locking direction being opposite to the first direction P; the second direction I being approximately perpendicular to the first direction P can also be considered as the second direction I being perpendicular to the first direction P. By adjusting the locking depth of the first screw 31 and / or the second screw 32, the first direction P is changed accordingly. Specifically, taking the adjustment of the locking depth of the first screw 31 as an example, the projection module 12 is subjected to the action of gravity or the locking force of the first screw 31, and rotates around the connection between the second screw 32 and the second fixed end 1212, thereby fine-tuning the orientation of the first direction P. Preferably, a spring is further provided between the first fixed end 1211 and the first boss, and a spring is further provided between the second fixed end 1212 and the second boss, so that when the locking depth of the first screw 31 and / or the second screw 32 is adjusted, the projection module 12 will not shake due to the change in the locking force. Preferably, the projection unit 121 has a head and a tail relative to each other, a projection lens is installed on the head of the projection unit 121, and the first fixed end 1211 and the second fixed end 1212 are arranged at the tail of the projection unit 121. By adjusting the locking depth of the first screw 31 and the second screw 32 corresponding to at least one of the first fixed end 1211 and the second fixed end 1212, the first direction P can be deflected at a larger angle. Preferably, when the projection module 12 is located at the projection position, the first direction P is inclined to the vertical direction Z, so that when the projection module 12 is affected by gravity or the locking force of the adjusted screw 3, the deflection angle of the first direction P is larger.
[0040] In addition, if Figure 6 and Figure 8As shown, the display screen bracket 1 also includes a control module 4, and the control module 4 is coupled to the projection module 12. The control module 4 is used to control the pixel array of the projection module 12 to generate the image content of the projection image, and the light generated by the light source of the projection module 12 passes through the pixel array to project the projection image onto the projection surface located in the first direction P. For example, the control module 4 is installed in the bracket body 11, or the control module 4 is installed in the display screen 2, but the present invention is not limited to this. It should be noted that the control module 4 can independently control the projection module 12, for example, the user can manipulate the control module 4 to generate an image signal for controlling the projection module 12 through a mechanical button or an external remote control device provided on the display device; or, the control module 4 can also be coupled to one of the display screen 2 or the computer host 5, so that the control module 4 can obtain the data of the projection image from the display screen 2 or the computer host 5. In this embodiment, Figure 6 As shown, the control module 4 is installed in the bracket body 11, and the control module 4 is coupled to the projection module 12 and the terminal set on the VESA component 13 through cables, and the terminal on the VESA component 13 is used to couple with the display screen 2, so that the control module 4 is coupled with the display screen 2. The display screen 2 and the computer host 5 are coupled through cables, so that the control module 4 can obtain the data of the projection picture from the computer host 5, and generate a control signal to drive the projection module 12 to project the projection picture; the display screen 2 can also generate an on-screen display control (On Screen Display, OSD) screen, so as to assist the user to operate the on-screen display control screen through the input module or external control device equipped on the display screen 2, so as to adjust the projection picture to the picture content desired by the user.
[0041] Based on the above, the display device provided by the present invention includes the above-mentioned display screen bracket 1 and the display screen 2. The display screen 2 is used to display the main picture. The display screen bracket 1 includes a bracket body 11 and a projection module 12, the bracket body 11 is used to carry the display screen 2, and the projection module 12 is used to project the projection picture in a first direction P. The projection picture is different from the main picture.
[0042] In summary, the display screen bracket provided by the present invention includes a bracket body and a projection module. The bracket body is used to carry the display screen, and the bracket body includes a housing cavity, and the housing cavity has an opening. The projection module is coupled to the bracket body, and the projection module is used to project a projection picture in a first direction, and the projection module is selectively located at a storage position or a projection position. Wherein, when the projection module is located at the storage position, the projection module is stored in the housing cavity, and the first direction is toward the inside of the housing cavity; when the projection module is located at the projection position, at least part of the projection module protrudes from the opening of the housing cavity, and the first direction is toward the outside of the housing cavity. Therefore, when the projection module is located at the projection position, there is a certain spacing distance between the projection picture projected and the main picture displayed on the display screen; the projection module can even be adjusted to the storage position when the projection picture does not need to be projected; therefore, while satisfying the user's lighting decoration or content display, it can also avoid the user from being distracted when watching the main picture.
[0043] The present invention has been described by the above-mentioned relevant embodiments, however, the above-mentioned embodiments are only examples for implementing the present invention.
