Detailed Implementation

[0034] Example 1:

[0035] like Figure 1 , 2 As shown in Figures 3, 4, and 5, a control display screen includes a back cover 1 and a front cover 2. A circuit board 4 is provided between the back cover 1 and the front cover 2. The front cover 2 is provided with a display screen 3, forming a complete display and control unit. The circuit board 4 is a circuit board used in existing automotive control displays, containing the existing required components and programs. The display screen 3 is preferably an LED display screen or a touch screen.

[0036] The back cover 1 is equipped with a heat dissipation mechanism 5, which is used to solve the heat dissipation problem when the display is working and to ensure that the internal electronic components are in a suitable working temperature environment.

[0037] In a preferred embodiment, the back cover 1 is provided with a plurality of connectors 201, which are existing connectors used by the display screen to connect to the vehicle's wiring harness, including but not limited to signal connectors, power connectors, electrical connectors and data connectors.

[0038] The display screen 3 is equipped with control buttons 301 for easy operation by the user, such as switching display interfaces and adjusting parameters.

[0039] In a preferred embodiment, the back cover 1 is provided with heat dissipation holes 6, which serve as outlet channels for heat dissipation and provide a path for hot air to be discharged.

[0040] The heat dissipation mechanism 5 includes a connecting shell 501, and a fan 508 is provided inside the connecting shell 501. The fan 508 is aligned with the heat dissipation hole 6. When working, the airflow generated by the fan 508 can quickly carry away the heat.

[0041] The back cover 1 has several connecting posts 504 inside, and the connecting shell 501 has several connecting blocks 505. The connecting blocks 505 correspond one-to-one with the connecting posts 504. The connecting blocks 505 and the connecting posts 504 are connected by screws. In use, the connecting shell 501 is connected by the connecting blocks 505, the connecting posts 504 and the screws, which facilitates the installation and disassembly of the heat dissipation mechanism 5 and facilitates later maintenance and repair.

[0042] A sealing gasket 509 is provided between the connecting housing 501 and the fan 508 to prevent airflow leakage, ensure that the airflow generated by the fan 508 can flow along a predetermined path, improve heat dissipation efficiency, and give the vent 507 sufficient negative pressure.

[0043] The connecting shell 501 has an air cavity 506 and several air holes 507, which are connected to the air cavity 506. The fan 508 is located in the air cavity 506, and the air holes 507 are connected to the internal space of the back shell 1, so that the airflow generated by the fan 508 is drawn in through the air holes 507 and finally discharged through the heat dissipation hole 6, thereby dissipating heat from the display screen of this application.

[0044] The outer side of the connecting shell 501 is provided with several air inlet pipes 502, which are connected to the air vents 507. The air inlet pipes 502 are provided with multiple air inlets 503, which are aligned with the circuit board 4. When the fan 508 is working, hot air is introduced through the air inlet pipes 502 and air inlets 503, thereby evenly absorbing the internal heat and finally expelling it through the heat dissipation holes 6. This enables comprehensive heat dissipation of the display screen of this application and ensures the heat dissipation effect.

[0045] The fan 508 is provided with several connecting ears 510, and the connecting ears 510 and the connecting shell 501 are provided with sockets 511; the back shell 1 is provided with several plug posts 512, which are adapted to the sockets 511. During installation, the plug posts 512 are positioned by the sockets 511 to facilitate the installation of the fan and the connecting shell 501.

[0046] When the control display screen is powered on, it begins to heat up. At this time, the heat dissipation mechanism 5 is activated, and the fan 508 starts to rotate. The airflow generated by the fan 508 creates negative pressure in the air chamber 506. This negative pressure acts on the air inlet 503, causing the internal hot air to pass sequentially through the air inlet 503, air inlet pipe 502, air hole 507, air chamber 506, and fan 508 before being discharged through the heat dissipation hole 6, thus completing the heat dissipation process.

[0047] Example 2:

[0048] like Figure 6 As shown, the back cover 1 and the front cover 2 are movably connected, and the electronic components, circuit boards 4 and display screen 3 connected to the back cover 1 and the front cover 2 are connected by existing connecting lines.

[0049] The front shell 2 has two symmetrical inclined surfaces 701 on the side near the back shell 1. The back shell 1 has a fixing plate 702 on the side near the front shell 2. The fixing plate 702 is hinged to the front shell 2 by a damping shaft 703. The damping shaft 703 can be an existing damping pivot. In use, the user can adjust the angle of the display screen 3 by rotating the front shell 2 for easy viewing and operation. The damping shaft 703 can limit the angle after rotation and prevent it from rotating randomly. The operation is simple and easy to use.
