Multifunctional control armrest screen Technical Field

[0001] This utility model belongs to the field of display screens, specifically relating to a multifunctional control armrest screen. Background Technology

[0002] An armrest screen is a smart interactive device integrated into the armrest of a seat, providing services for multiple scenarios through touch screens, sensing technology, buttons, and more.

[0003] Existing armrest screens typically use TFT displays. Since the content that armrest screens need to display is relatively simple in most cases, such as displaying the working status of the air conditioner, adjusting the air conditioner temperature, air volume, mode, and displaying the seat posture and position, the cost of armrest screens is increased because TFT displays, which are widely used in televisions, computer monitors, and mobile phones and require high resolution and high color gamut, are used.

[0004] Therefore, determining the appropriate display screen for armrest screens is an urgent issue that needs to be addressed. Summary of the Invention

It should be noted that the following are only some specific embodiments of the present utility model, and the specific and direct descriptions of related structures are merely for the convenience of understanding the present utility model; the specific features do not necessarily or directly limit the scope of implementation of the present utility model. Conventional choices and substitutions made by those skilled in the art under the guidance of the present utility model should all be considered within the scope of protection claimed by this utility model.

[0039] As shown in Figures 1-6, this utility model discloses a multifunctional control armrest screen, including a housing 1. The housing 1 is provided with a circuit board 2, a segment code screen 3, a touch panel 4, a cover plate 5, and a light source 6. The circuit board 2, the segment code screen 3, the touch panel 4, and the cover plate 5 are arranged in a forward-facing manner, with the touch panel 4 covering the segment code screen 3 and the cover plate 5 covering the touch panel 4. The segment code screen 3, the touch panel 4, and the light source 6 are respectively connected to the circuit board 2, and the light source 6 is used to illuminate the segment code screen 3.

[0040] Therefore, the use of segment display 3 reduces the production cost of the armrest screen, and the segment display 3, together with the light source 6, can effectively display specific content to meet the needs of the armrest screen. In addition, the arrangement of touch panel 4 covering segment display 3 and cover plate 5 covering touch panel 4 allows the touch cover plate 5 to generate corresponding input electrical signals on touch panel 4. The input electrical signals are transmitted to circuit board 2, and after calculation by circuit board 2, output electrical signals are generated. The output electrical signals are transmitted to segment display 3 to control segment display 3 and realize the display changes of segment display 3. In addition, the arrangement of cover plate 5 can effectively protect touch panel 4.

[0041] Specifically, in this embodiment, the segment code screen 3 can be an Akita Micro CGS556A00-VLN-RT segment code screen, etc., and the touch panel 4 can be a Zhongpei Optoelectronics ZP10660-123-10200 touch panel, etc.

[0042] Preferably, in this embodiment, a first optical adhesive layer 71 is provided between the segment code screen 3 and the touch panel 4 to optically bond and fix the segment code screen 3 and the touch panel 4; a second optical adhesive layer 72 is provided between the touch panel 4 and the cover plate 5 to optically bond and fix the touch panel 4 and the cover plate 5.

[0043] The first optical adhesive layer 71 and the second optical adhesive layer 72 improve the stability of the connection between the segment code screen 3, the touch panel 4 and the cover plate 5, and make the touch panel 4 more sensitive to the touch on the cover plate 5.

[0044] The first optical adhesive layer 71 and the second optical adhesive layer 72 can be made of OCA or OCR. In this embodiment, the first optical adhesive layer 71 is made of OCA and the second optical adhesive layer 72 is made of OCR.

[0045] In addition, in this embodiment, a PC film 51 is provided on the side of the cover plate 5 away from the touch panel 4, which can effectively improve the explosion-proof capability of the cover plate 5 and increase its safety after being subjected to external impact.

[0046] Specifically, the PC film 51 and the cover plate 5 are formed using the IML process.

[0047] Preferably, the outer edge of the cover plate 5 is provided with a convex curved surface 52, so that when the outer edge of the cover plate 5 is subjected to an external force impact, stress concentration is less likely to occur on the curved surface 52, thereby making the cover plate 5 less likely to break due to impact.

[0048] The cover plate 5 has a transparent window in the middle and a black, opaque outer perimeter.

[0049] In addition, the light source 6 in this embodiment uses multiple LED beads 61, and each LED bead 61 is arranged in a matrix on the side of the circuit board 2 facing the segment code screen 3. The housing 1 is provided with multiple light guide channels 11 arranged in a matrix. At least one LED bead 61 is covered at one end of each light guide channel 11, and the other end of each light guide channel 11 faces the segment code screen 3.

[0050] Therefore, by using a number of LED beads 61 in conjunction with a number of light guide channels 11, different LED beads 61 can emit light through different light guide channels 11. Thus, the circuit board 2 controls the emission of LED beads 61 to present different emission conditions, thereby achieving diverse displays in conjunction with the segment code screen 3.

[0051] Specifically, the housing 1 includes a rear outer shell 12 and a front light guide bracket 13. The outer shell 12 has an assembly cavity 121 with a front opening. The light guide bracket 13 is disposed on the outer shell 12 to close the opening of the assembly cavity 121. The circuit board 2 is disposed on the rear side of the light guide bracket 13 and located inside the assembly cavity 121. The segment code screen 3, the touch panel 4, and the cover plate 5 are disposed on the front side of the light guide bracket 13 and located outside the assembly cavity 121. Each light guide is disposed on the light guide bracket 13. In addition, a through-hole 131 is provided on the top of the light guide bracket 13. A first connecting strip 81 passing through the through-hole 131 is provided between the segment code screen 3 and the circuit board 2 to electrically connect the segment code screen 3 and the circuit board 2. A second connecting strip 82 passing through the through-hole 131 is provided between the touch panel 4 and the circuit board 2 to electrically connect the touch panel 4 and the circuit board 2.

[0052] Therefore, the circuit board 2, segment code screen 3, touch panel 4 and cover plate 5 are assembled and then combined onto the housing 12 while the light guide bracket 13 and the housing 12 are in a separate state.

[0053] The outer shell 12 and the light guide bracket 13 can be fixed and installed by means of snap-fit, adhesive, bolts, etc.

[0054] In addition, a sealing ring 9 is provided between the cover plate 5 and the light guide bracket 13. The segment code screen 3 and the touch panel 4 are located on the inner circumference of the sealing ring 9 so that the segment code screen 3 and the touch panel 4 can be sealed and protected through the sealing ring 9.

[0055] Among them, the light guide bracket 13 is an integrally molded injection molded part. The light guide bracket 13 has a light guide part with the same front and rear length as the light guide channel 11. During injection molding, the light guide channel 11 is formed by filling the area of ​​the light guide channel 11 with the mold.

[0056] Preferably, the thickness of the touch panel 4 is d, where 0.5mm≤d≤1mm, and in this embodiment, 0.7mm is used.

[0057] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
