[0035] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] Please see the appendix Figures 1-14 This application provides the following technical solutions.

[0037] Example 1: A housing structure for a display device includes a display housing 1. A component mounting box 29 is provided on the back of the display housing 1. An adjustment mounting box 2 is provided at the upper end of the component mounting box 29. A connecting groove is provided on one side of the adjustment mounting box 2. An adjustment connecting assembly is provided within the connecting groove. The adjustment connecting assembly includes a hollow ball head 4, a combined ball sleeve 5, and a central air inlet pipe 7. The hollow ball head 4 and the combined ball sleeve 5 are fitted together. A disassembly / assembly plate 3 is fixedly installed in the connecting groove by bolts. The hollow ball head 4 is fixedly connected to the disassembly / assembly plate 3 by several bolts. One side of the hollow ball head 4 is rotatably inserted into the combined ball sleeve 5. The combined ball sleeve 5 includes two components, which are connected through... The hollow ball head 4 is connected via a flange assembly. An embedded groove is provided on the outer periphery of the hollow ball head 4, which is inserted into the combined ball sleeve 5. A damping pad 6 is inserted into the embedded groove. Several second rod sleeves 9 are provided on the inner periphery of the hollow ball head 4. Several first through grooves are provided in the center of the several second rod sleeves 9, which are connected to the embedded groove. The hollow ball head 4 can rotate within the combined ball sleeve 5. When the combined ball sleeve 5 is fixed, the display housing 1 can be adjusted in multiple directions by rotating the hollow ball head 4 within the combined ball sleeve 5. The damping pad 6 can achieve damping self-positioning between the combined ball sleeve 5 and the hollow ball head 4. The damping pad 6 can be an elastic metal structure with two damping rubber layers.

[0038] The central air inlet pipe 7 is horizontally positioned at the center of the display housing 1, located at the center of the disassembly and assembly panel 3. An air inlet groove 13 is formed at the center of the central air inlet pipe 7. Several first rod sleeves 8 are provided on the outer periphery of the central air inlet pipe 7, and these first rod sleeves 8 are correspondingly arranged with several second rod sleeves 9. Each of the first rod sleeves 8 is connected to an air inlet groove 13, which has a piston groove. A second through groove is formed in the upper end of the piston groove, penetrating through the second rod sleeve 9. A pressing piston 11 is movably inserted into the piston groove. A pressing rod 10 is vertically positioned at the upper end of the pressing piston 11. The upper end of the pressing rod 10 movably passes through the second through groove and is inserted into the second rod sleeve 9. In the first through slot, one end of the clamping rod 10 is inserted into the first through slot and abuts against the inner side of the damping pad 6. The clamping rod 10 is sleeved with a first spring 12 on one side of the piston slot. When high-pressure air is introduced into the air inlet slot 13 of the central air pipe 7, the high-pressure air can push the first spring 12 and the clamping rod 10 to move along the second rod sleeve 9 and the first rod sleeve 8. At this time, the clamping rod 10 can push the damping pad 6 to deform, so as to achieve contact and clamping between the combined ball sleeve 5 and the hollow ball head 4, and avoid the relative movement of the combined ball sleeve 5 and the hollow ball head 4 caused by the shaking of the display housing 1 with the carrier.

[0039] An internal support assembly is provided for elastic support. A combined cavity is opened on the front of the display housing 1, and the internal support assembly is located within the combined cavity. The internal support assembly includes a fixing frame 15, a mounting frame 16, an elastic connecting ring 19, and two spacer bars 21. The two spacer bars 21 are horizontally positioned on the upper and lower sides of the combined cavity. A central groove 14 is vertically opened on the side of the display housing 1 near the air inlet groove 13, and the air inlet groove 13 communicates with the central groove 14. The fixing frame 15 is located within the combined cavity of the display housing 1, and the mounting frame 16 is inserted into the combined cavity and fixedly connected to the side of the fixing frame 15 by bolts. Two connecting tubes 17 are horizontally positioned on the side of the mounting frame 16 near the central groove 14, and the two connecting tubes 17 pass through... The fixed frame 15 is inserted into the intermediate groove 14. A rubber mounting ring 18 is glued and embedded on the inner circumference of the mounting frame 16. An elastic connecting ring 19 is provided on one side of the rubber mounting ring 18. The elastic connecting ring 19 is hollow. The connecting tube 17 passes through the mounting frame 16 and the rubber mounting ring 18 and is connected to the elastic connecting ring 19. The bolts connecting the mounting frame 16 and the fixed frame 15 are offset from the connecting tube 17. The high-pressure air entering the air groove 13 will enter the elastic connecting ring 19 through the intermediate groove 14, the connecting tube 17, and the transition groove 20. The elastic connecting ring 19 is an elastic rubber structure with a certain shape support. When high-pressure gas is introduced into the elastic connecting ring 19, the elastic connecting ring 19 will expand.

[0040] Each of the two spacers 21 has a horizontally opened distribution groove 25 on one side. One side of the distribution groove 25 is connected to the middle groove 14 and a one-way valve 27 is inserted. On the side of the distribution groove 25 away from the middle groove 14, a guide strip 26 is provided through an elastic clip. Several air blowing grooves 28 are opened through the distribution groove 25 between the one-way valve 27 and the guide strip 26. The component mounting box 29 has connecting windows on both sides that are connected to the combined cavity of the display housing 1. Each connecting window is connected to a ventilation baffle 30. When the high-pressure gas in the middle groove 14 cannot expand and support the elastic connecting ring 19 and the movement of the clamping rod 10, additional high-pressure air will break through from the one-way valve 27 and enter the distribution groove 25. Then it will be blown into the combined cavity of the display housing 1 from the several air blowing grooves 28. At this time, the combined cavity is filled with high-speed airflow. The high-speed airflow can enter the component mounting box 29 from the ventilation baffle 30 and then be discharged from the component mounting box 29. During this process, heat dissipation and cooling treatment can be performed on the electrical components in the display housing 1 and the electrical components in the component mounting box 29.

[0041] A car center console using a shell structure includes a display screen assembly 23 and an edge sealing plate 39. An assembly groove 24 is formed on the outer side of the display screen assembly 23, and an elastic connecting ring 19 is inserted into the assembly groove 24. A guide strip 26 is provided on one side of a spacer strip 21, and an anti-collision strip 22 is fitted onto it. The side of the anti-collision strip 22 contacts the display screen assembly 23. Both sides of the edge sealing plate 39 contact the sides of the display screen assembly 23 and the display shell 1, respectively. A cover panel 38 is adhered and covered on the outer sides of the display shell 1 and the display screen assembly 23 that contact the edge sealing plate 39. The elastic connecting ring 19 is inserted into... After being inserted into the assembly slot 24, the elastic connecting ring 19 can provide elastic support for the display assembly 23. When the car is bumpy, it can reduce the vibration loss of the display assembly 23. The edge sealing plate 39 can be an elastic plastic or elastic metal structure to provide elastic support and positioning for the display assembly 23. When the spacer strip 21 blows airflow into the display housing 1, it can carry away the heat of the display assembly 23, avoiding the impact of the high temperature environment inside the car on the life of the display assembly 23. The connection between the cover panel 38 and the display housing 1 and the display assembly 23 can be an elastic snap-fit ​​connection.

[0042] Example 2: Based on Example 1, a flip-operation component is provided to improve the appearance of the display housing 1 while increasing its practicality. The flip-operation component is movably located at the lower end of the display housing 1. The flip-operation component includes an operation control panel 35 and two arc-shaped piston rods 36. The two arc-shaped piston rods 36 are located on both sides of the operation control panel 35 and are movably inserted into the lower end of the display housing 1. A common groove 32 is horizontally opened at the lower end of the middle groove 14. A connecting ear is provided on one side of the lower end of the display housing 1. A support pin 34 is inserted into one side of the operation control panel 35 and is connected to the connecting ear. An arc-shaped piston groove 33 is opened in the common groove 32 on both sides of the display housing 1. One side of each of the two arc-shaped piston rods 36 is movably inserted into the arc-shaped piston groove 33. A flip piston is provided on the side of the arc-shaped piston rod 36 inserted into the arc-shaped piston groove 33 and close to the common groove 32. A second spring 37 is fitted on one side of the arc-shaped piston groove 33. The virtual axis of the arc-shaped piston rod 36 is coaxially set with the support pin 34. When the arc-shaped piston rod 36 extends out of the arc-shaped piston groove 33, one side of the actual operation control row 35 forms an angle with the lower end of the display housing 1. The actual operation control row 35 is provided with control buttons on one side of the angled area. Before the high-pressure air in the intermediate groove 14 enters the distribution groove 25 from the one-way valve 27, the high-pressure air can enter the two arc-shaped piston grooves 33 from the common groove 32, and then push the two arc-shaped piston rods 36 and control the actual operation control row 35 to flip, so that the control buttons of the actual operation control row 35 are exposed for easy use by the operator. When the display housing 1 is used in the central control display screen of an automobile, the automobile needs to have a small air compressor built in. When the automobile starts, the small air compressor is powered on and high-pressure gas can be sent into the air inlet groove 13 and the intermediate groove 14.
