Description

Technical Field

[0001] The present invention belongs to the technical field of TV cabinets, and in particular relates to a TV cabinet with an opening and closing mechanism capable of hiding a laser TV. Background Art

[0002] Laser TV is a projection display device that uses laser light source as display light source and cooperates with front projection display technology to form images. It is equipped with a dedicated projection screen and can receive radio and television programs or Internet TV programs.

[0003] There are two existing ways to install laser TVs: the first is to place it directly on a widened TV cabinet. This method allows the laser TV to be moved freely when in use, and the laser TV has better heat dissipation, but it will take up space when not in use; at the same time, this method of use is limited by the projection size requirements of the laser TV cabinet, which will cause the width of the TV cabinet to be too wide, affecting the appearance of the TV cabinet and compressing the living room's usable space. The second method is to embed it directly into the cabinet, and add glass to the TV cabinet panel to achieve the purpose of not blocking the laser TV lens. In this way, the TV cabinet needs to be customized, and the width of the TV cabinet will increase. In addition, the laser TV light passing through a layer of glass will cause the projection quality to decline, and the internal heat dissipation effect is not good, which will cause heat accumulation at the laser TV heat dissipation port, resulting in a shortened service life of the laser TV. Summary of the invention

[0028] like Figures 1 to 6 As shown, a TV cabinet with an opening and closing mechanism that can hide a laser TV includes a box body 1 and a laser TV 5 placed in the box body 1. The box body 1 includes a top plate 3, a bottom plate 35, and a front panel 2, a rear panel 27 and two side panels 28 vertically connected to the two (top plate 3, bottom plate 35). The front panel 2 is hinged to the bottom plate 35 and can be opened by flipping down, which is convenient for the installation and debugging of the laser TV 5.

[0029] like Figure 2 and Figure 3 As shown, the lower surface of the top plate 3 is provided with an opening and closing mechanism, and the opening and closing mechanism is connected with an intermediate panel 4 that can be opened and closed on the upper surface of the top plate 3. The opening and closing mechanism includes a linkage shaft 7 and two parallel screw nuts 8 perpendicular to the linkage shaft 7. Both ends of the linkage shaft 7 and the screw nuts 8 are fixed to the lower surface of the top plate 3 through a bearing seat 11. Both ends of the linkage shaft 7 are provided with a first bevel gear 9, and the end of the screw nut 8 close to the linkage shaft 7 is provided with a second bevel gear 10 meshing with the first bevel gear 9. The linkage shaft 7 is connected to a driving motor 12, and the screw nuts 8 are sleeved with a moving block 13. The moving block 13 is connected with an L-shaped sheet metal 14, and the sheet metal 14 is connected to the side of the intermediate panel 4. The driving motor 12 is a stepping motor, which can prevent hand pinching and increase safety protection.

[0030] like Figure 2 and Figure 3 As shown, the lower surface of the top plate 3 is provided with a stopper 15 located at both ends of the screw nut 8, and the sheet metal 14 is provided with a contact hook that can touch the stopper 15. The stopper 15 includes a stopper body 25 fixed to the lower surface of the top plate 3, and the stopper body 25 is connected to an elastic connecting rod 24, and a contact 23 is provided at the end of the connecting rod 24. The top plate 3 is provided with a long strip-shaped fixing hole 30 parallel to the screw nut 8, and the stopper body 25 is fixed by passing a bolt 29 through the fixing hole 30. The contact hook includes a parallel first crossbar 26 and a second crossbar 32, and a vertical rod 31 is vertically connected between the first crossbar 26 and the second crossbar 32. The vertical angle between the first crossbar 26 and the vertical rod 31 and the vertical angle between the second crossbar 32 and the vertical rod 31 can touch the two contacts 23 respectively. When the contact hook touches one of the stoppers, the middle panel 4 is in an open state, and when the contact hook touches the other stopper 15, the middle panel 4 is in a closed state.

[0031] like Figure 4 and Figure 5The present invention also includes a heat dissipation mechanism, which includes a heat dissipation fan 6, an air inlet 16 and an air outlet 17. Two partitions 33 parallel to the side panel 28 are provided in the box body 1 and separate the two sides of the box body 1 into two ventilation chambers 34. The heat dissipation fan 6 is provided on the partitions 33. The rear panel 27 is located at the position of the two ventilation chambers 34 and is respectively provided with an air inlet 16 and an air outlet 17. The air inlet 16 is located at the heat dissipation air inlet side of the laser TV 5, and the air outlet 17 is located at the heat dissipation air outlet side of the laser TV 5. Figure 5 As indicated by the arrows, the outside wind enters from the air inlet 16, then passes through the heat dissipation air inlet side and heat dissipation air outlet side of the laser TV in turn, and finally flows out from the air outlet 17. The air flow rate is greater than the fan flow rate configured for the laser TV 5, and all the hot air discharged by the laser TV 5 is discharged from the box 1. The air inlet 16 and the air outlet 17 are both mesh plate structures, which ensure heat dissipation while maintaining beauty. The heat dissipation mechanism also includes a vent 19 located in the center of the rear panel 27 to enhance ventilation and heat dissipation.

[0032] like Figure 6 As shown, a docking mechanism 18 is provided on the side panel 28, and the docking mechanism 18 includes an AC external power socket 20, a network cable interface 21 and an RS232 Internet of Things interface 22 which are arranged in sequence from top to bottom. The AC external power socket 20, the network cable interface 21 and the RS232 Internet of Things interface 22 are all connected to the laser TV 5 through an intermediate line, which is convenient for connecting external high-definition devices and other peripheral devices without taking out the laser TV 5. The RS232 Internet of Things interface 22 allows the laser TV 5 to be docked with the smart home system control protocol.

[0033] The present invention also includes a control mechanism, which includes a remote controller and a control main board connected to each other. The drive motor 12, the laser TV 5, the cooling fan 6, and the limiter 15 are electrically connected to the control main board respectively.

[0034] The working principle of the present invention is as follows: when the switch of the remote control is pressed, the driving motor 12 starts, the linkage shaft 7 rotates, driving the screw nuts 8 on both sides to rotate, and the moving block 13 and the sheet metal 14 move along the screw nuts 8 toward the direction of the rear panel 27, and the middle panel 4 then translates toward the direction of the rear panel 27. When the hook touches the limiter, the signal is fed back to the control main board, and the control main board sends a signal to stop the driving motor 12. At this time, the middle panel 4 is fully opened, and the lens of the laser TV 5 is exposed; when the remote control switch is turned on, the laser TV 5 starts to play, and the cooling fan 6 starts to dissipate heat, and discharges the heat generated by the laser TV 5 out of the box. When the switch of the remote control is pressed, the laser TV 5 is turned off, the cooling fan 6 stops working, the drive motor 12 is started, and the linkage shaft 7 rotates in the opposite direction, driving the screw nuts 8 on both sides to rotate in the opposite direction, and the moving block 13 and the sheet metal 14 move along the screw nuts 8 toward the front panel 2, and the middle panel 4 moves horizontally in the direction of the front panel 2. When the hook touches the other limiter 15, the signal is fed back to the control main board, and the control main board sends a signal to stop the drive motor 12. At this time, the middle panel 4 is completely closed to hide the laser TV 5.
