TECHNICAL FIELD
[0001] The utility model relates to a display, especially a double-knob vehicle-mounted display screen. BACKGROUND
[0002] The vehicle-mounted display screen is generally installed on the center console of the car, and most of the existing display screens adopt the embedded mode, only the screen part is exposed, and the back of the display screen is hidden in the center console. However, the display screen will generate a certain amount of heat during the working process. If the heat cannot be dissipated in time, it will easily affect the performance and service life of the display screen. In addition, in the traditional display screen product, the display layer and the PCB board are generally in a front-rear stacked structure. This stacking mode cannot guarantee the timely dissipation of the heat of the display layer, and it is difficult to set a radiator that can assist the display layer in dissipating heat. Therefore, the heat dissipation capacity is still insufficient, which cannot meet the application requirements. SUMMARY
[0003] The technical problem to be solved by the utility model is to provide a double-knob vehicle-mounted display screen with compact structure, reasonable layout, and better heat dissipation performance in view of the deficiencies of the prior art.
[0004] To solve the above technical problems, the utility model adopts the following technical scheme.
[0005] A double-knob vehicle-mounted display screen comprises a screen frame base, a display layer, a TP layer, a PCB board, and a radiator. The display layer is embedded in the screen frame base. The TP layer is attached to the front side of the display layer. The PCB board is in a long strip shape, and the PCB board is arranged below the TP layer. The front side of the PCB board is provided with two knob adjustment devices. The front side of the TP layer is provided with two knobs, which are arranged at the front ends of the two knob adjustment devices. The back side of the screen frame base is provided with a mounting port. The radiator passes through the mounting port, and the radiator and the back of the display layer are attached to each other.
[0006] Preferably, the lower end of the screen frame base is formed with a step portion protruding forward, and the PCB board is fixed to the back of the step portion.
[0007] Preferably, the front side of the step portion is provided with two key ports, and the key ports are inserted with keycaps that can move forward and backward. The keycaps are arranged in alignment with the keys on the PCB board.
[0008] Preferably, a silica gel pad is attached to the front side of the PCB board.
[0009] Preferably, two silica gel plugs are arranged between the display layer and the screen frame base.
[0010] Preferably, a strip-shaped rear cover is fixed to the back side of the step portion, and the strip-shaped rear cover covers the rear side of the PCB board.
[0011] Preferably, the lower end of the TP layer has an insert opening, which is aligned with the button opening.
[0012] In the dual-knob vehicle-mounted display screen disclosed in this utility model, the screen frame base serves as the main housing of the display screen. The display layer is embedded inside the screen frame base, and the TP layer is attached to the front side of the display layer. The PCB board is installed inside the screen frame base below the TP layer. Two knobs are respectively installed at the front ends of two knob adjustment devices on the PCB board. In the above structure, the display layer and the PCB board are not stacked in a front-back relationship. The PCB board is set as a long strip, which not only makes the internal structure of the display screen compact and reasonable in layout, but also allows the heat sink to be easily passed through the mounting port on the back side of the screen frame base, so that the heat sink and the back of the display layer are in close contact, thereby improving heat dissipation performance and better meeting the application requirements.

[0013] Figure 1 Disassembly of the dual-knob vehicle display screen of this utility model Figure 1 . Detailed Implementation
[0014] The present invention will now be described in more detail with reference to the accompanying drawings and embodiments.
[0015] This utility model discloses a dual-knob vehicle display screen, such as... Figure 1 As shown, it includes a screen frame base 1, a display layer 2, a TP layer 3, a PCB board 4, and a heat sink 5. The display layer 2 is embedded in the screen frame base 1. The TP layer 3 is attached to the front side of the display layer 2. The PCB board 4 is elongated and located below the TP layer 3. The front side of the PCB board 4 is provided with two rotary adjustment devices. The front side of the TP layer 3 is provided with two knobs 6, which are located at the front ends of the two rotary adjustment devices. The back side of the screen frame base 1 has a mounting opening 10. The heat sink 5 passes through the mounting opening 10 and is attached to the back of the display layer 2.
[0016] In the structure, the screen frame base 1 serves as a main housing of the display screen, the display layer 2 is embedded in the inside of the screen frame base 1, the TP layer 3 is attached to the front side of the display layer 2, the PCB board 4 is installed in the screen frame base 1 below the TP layer 3, and the two knobs 6 are respectively installed at the front ends of the two knob adjusting devices on the PCB board 4. In the structure, the display layer 2 and the PCB board 4 are not in a front-back stacking relationship, and the PCB board 4 is in a strip shape, so that the internal structure of the display screen is compact and the layout is reasonable. In addition, the mounting port 10 is arranged on the back side of the screen frame base 1, so that the heat sink 5 can pass through the mounting port 10, the heat sink 5 and the back of the display layer 2 are attached to each other, and the heat dissipation performance is improved, thereby meeting the application requirements.
[0017] The PCB board 4 is preferably installed on the back side of the screen frame base 1. In order to reliably fix the PCB board 4, in the embodiment, the lower end of the screen frame base 1 is formed with a step portion 11 protruding forward, and the PCB board 4 is fixed to the back of the step portion 11.
[0018] As a preferred mode, as shown in Figure 1 , two key openings 12 are arranged on the front side of the step portion 11, the key cap 13 movably arranged in the key opening 12 is in alignment with the key on the PCB board 4. In the structure, the step portion 11 is arranged at the lower end of the screen frame base 1, which can reliably support and fix the PCB board 4, and provide space for the key cap 13 to be embedded and move forward and backward, thereby further ensuring the compactness of the structure and meeting the requirements of the reasonable layout. In addition, the step portion 11 has a certain front-back width, so that the front-back depth of the key opening 12 is larger, which helps the key cap 13 to slide forward and backward flatly, and the key feeling is better.
[0019] In order to play an insulating protection role for the PCB board 4, in the embodiment, a silica gel pad 40 is attached to the front side of the PCB board 4.
[0020] As a preferred mode, please refer to Figure 1 , two silica gel plugs 14 are arranged between the display layer 2 and the screen frame base 1. The silica gel plug 14 mainly plays an elastic buffering role, and in addition, when the screen frame base 1 is an alloy screen frame, the silica gel pad 40 and the silica gel plug 14 can both play an insulating role.
[0021] In order to protect the strip-shaped PCB 4 well, a strip-shaped back cover 7 is fixed to the back side of the step part 11 in the embodiment, and covers the back side of the PCB 4. In practical application, the strip-shaped back cover 7 can be fixed to the back side of the step part 11 by screws.
[0022] Please see Figure 1 The lower end of the TP layer 3 is provided with an embedding opening 30, which is arranged in alignment with the key opening 12. In the embodiment, the embedding opening 30 mainly plays a role of avoiding, so that the key cap 13 can be extended outward.
