Description

Technical Field

[0001] This utility model relates to the field of vehicle display technology, specifically to a vehicle display backplate with partitioned heat dissipation ducts. Background Technology

[0002] As the core supporting component of the display screen, the back panel of the vehicle display screen must have mechanical strength, heat dissipation performance and electromagnetic shielding to ensure the stable operation of the display screen in the complex vehicle environment.

[0003] Currently, traditional vehicle display screen back panels are mainly made of metal (such as aluminum alloy) or plastic, and passive heat dissipation is achieved by opening simple heat dissipation holes. However, traditional back panels still have the following defects.

[0004] Traditional backplates rely solely on natural convection cooling through ventilation holes, resulting in limited heat dissipation area. This fails to meet the heat dissipation requirements of high-power displays (such as OLED and large-size LCD screens), and can easily lead to heat accumulation, especially in high-temperature environments. The lack of active cooling or efficient heat conduction structures in the traditional backplates results in uneven heat distribution, and localized overheating may cause display response delays, color distortion, or even damage. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a vehicle display screen backplate with partitioned heat dissipation ducts, solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] The vehicle display screen back panel with partitioned heat dissipation air ducts includes: a back shell, in which a central air duct is provided at the bottom, a fan is fixedly installed inside the central air duct, four sets of sub-air ducts are provided on the back shell outside the central air duct, and branch air ducts are provided between the sub-air ducts and the central air duct. Side air ducts are provided at the bottom inside the back shell, and the side air ducts are distributed on both sides of the central air duct. Filter screen one and filter screen two are fixedly installed inside the side air ducts and sub-air ducts respectively.

[0008] The mounting component is fixedly installed at the bottom of the back cover, and the mounting component has a docking sleeve that connects with the central air duct.

[0009] Furthermore, the sub-air ducts are arranged in a rectangular array and distributed around the central air duct.

[0010] Furthermore, the back shell has connector mounting ports on both sides, and an internal rubber gasket is fixed to the inner wall of the back shell.

[0011] Furthermore, air vents are evenly distributed at the bottom of the back shell at the location of the side air duct, and the air vents are interconnected with the side air duct.

[0012] Furthermore, the mounting component also includes mounting feet, with mounting feet fixedly mounted on both sides of the mounting frame, and mounting holes provided on the mounting feet. The mounting frame is provided with a snap-fit ​​opening, and a connector communicating with the mating sleeve is fixedly mounted on the bottom of the mounting frame.

[0013] Furthermore, the central air duct and the sub-air duct are connected, and the side air duct is a trough.

[0014] This invention provides a vehicle-mounted display screen backplate with partitioned heat dissipation air ducts. Compared with the prior art, it has the following advantages:

[0015] 1. Simple structure and good heat dissipation, making it particularly suitable for built-in installation of vehicle displays;

[0016] 2. By cooperating with the central air duct and the side air duct, the back panel achieves zoned heat dissipation, expands the heat dissipation area, and the two use a combination of one main and one auxiliary air duct to not only meet the daily heat dissipation needs of the back panel, but also to actively dissipate heat under high temperature conditions, thereby improving heat dissipation efficiency.

[0017] 3. The installation components enable personnel to install and secure the back cover, ensuring that the back cover is successfully connected to the vehicle structure. Attached Figure Description

[0029] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments of this utility model are described clearly and completely. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model. Example

[0030] To address the technical problems mentioned in the background section, the following automotive display screen backplate with partitioned heat dissipation ducts is provided:

[0031] Combination Figures 1-3 As shown, the vehicle display screen back panel with partitioned heat dissipation air ducts provided by this utility model includes a back shell 100, in which a central air duct 101 is provided at the bottom, and a fan 200 is fixedly installed inside the central air duct 101. Four sets of sub-air ducts 103 are provided on the back shell 100 outside the central air duct 101. Branch air ducts 102 are provided between the sub-air ducts 103 and the central air duct 101. Side air ducts 104 are provided at the bottom inside the back shell 100, and the side air ducts 104 are distributed on both sides of the central air duct 101. A filter screen 500 and a filter screen 600 are fixedly installed inside the side air ducts 104 and the sub-air ducts 103, respectively.

[0032] The central air duct 101 is a backup air duct structure and uses the internal fan 200 for active heat dissipation. The central air duct 101 utilizes the connection and cooperation of the peripheral sub-air ducts 103 and branch air ducts 102 to achieve multi-point ventilation and heat dissipation of the back panel. This effectively addresses the problem of excessive internal temperature of the display and inadequate daily ventilation and heat dissipation. The side air ducts 104 enable daily ventilation and heat dissipation of the back panel. Furthermore, the central air duct 101 is partitioned with the central air duct 101, which expands the heat dissipation area of ​​the back panel and ensures the operating intensity of the vehicle display.

[0033] The mounting component 300 is fixedly installed at the bottom of the back cover 100, and the mounting component 300 has a docking sleeve 400 that is connected to the central air duct 101.

[0034] Mounting component 300 enables personnel to install and fix the back cover, ensuring that the back cover 100 completes the installation connection with the vehicle structure. During installation, docking sleeve 400 connects with central air duct 101. When personnel are deploying the vehicle central control system, they can connect it to the external port of docking sleeve 400 through the air duct to connect it with the vehicle's air duct assembly. In this way, the air intake of air duct 103 and the air outlet of central air duct 101 can be synchronized with the vehicle's fresh air system.

[0035] In this embodiment, the sub-air ducts 103 are arranged in a rectangular array and distributed around the central air duct 101.

[0036] By using a rectangular array of sub-air ducts 103 arranged around the central air duct 101, ventilation and heat dissipation can be provided for areas that cannot be completely covered by the central air duct 101 and the side air ducts 104.

[0037] In this embodiment, connector mounting ports 105 are provided on both sides of the back cover 100, and an internal rubber pad 106 is fixedly connected to the inner wall of the back cover 100.

[0038] The connector mounting port 105 is the basic structure of the back shell 100, ensuring that it can be used with the monitor for external wiring terminals, and ensuring that the wire terminals on the monitor can be installed in the connector mounting port 105.

[0039] The built-in rubber gasket 106 ensures a tight seal between the back cover 100 and the display after assembly.

[0040] In this embodiment, air vents 107 are evenly distributed at the bottom of the back cover 100 at the location of the side air duct 104, and the air vents 107 are connected to the side air duct 104.

[0041] The air vent 107 is connected to the side air duct 104 to ensure the ventilation effect between the back cover 100 and the inside and outside through the air vent 107. During daily operation, air circulates between the inside and outside of the back cover 100 through the air vent 107.

[0042] In this embodiment, the mounting component 300 further includes mounting feet 303. Mounting feet 303 are fixedly mounted on both sides of the mounting bracket 301, and mounting feet 303 are provided with mounting holes 3031. Mounting bracket 301 is provided with a snap-fit ​​opening 3011. A connector 302 communicating with the docking sleeve 400 is fixedly mounted on the bottom of the mounting bracket 301.

[0043] By using the mounting holes 3031 on the mounting foot plate 303 to cooperate with the mounting parts, the auxiliary back cover 100 can be installed and fixed, thus enabling it to complete its assembly. During installation, in order to ensure that the mounting holes 3031 correspond to the mounting holes on the vehicle structure, personnel can first use the snap-fit ​​openings 3011 on the mounting bracket 301 to snap and fix it with the snap-fit ​​blocks on the internal structure. This ensures that the mounting holes correspond to each other, making it easy for personnel to quickly install and fix the device.

[0044] In this embodiment, the central air duct 101 and the sub-air duct 103 are connected, and the side air duct 104 is a trough.

[0045] The through-flow configuration of the central air duct 101 and the sub-air duct 103 facilitates the installation of air ducts at their external ports, ensuring that the air ducts are connected and coordinated with the vehicle's fresh air system; while the side air duct 104 in the trough can be ventilated by relying on the air window 107.

[0046] Working principle and usage process of this utility model:

[0047] During installation:

[0048] By using the mounting holes 3031 on the mounting foot plate 303 to cooperate with the mounting parts, the auxiliary back cover 100 can be installed and fixed, thus enabling it to complete its assembly. During installation, in order to ensure that the mounting holes 3031 correspond to the mounting holes on the vehicle structure, personnel can first use the snap-fit ​​openings 3011 on the mounting bracket 301 to snap and fix it with the snap-fit ​​blocks on the internal structure. This ensures that the mounting holes correspond to each other, making it easy for personnel to quickly install and fix the back cover.

[0049] During heat dissipation:

[0050] The side air duct 104 enables the back panel to perform daily ventilation and heat dissipation operations, and is set up separately from the central air duct 101;

[0051] The central air duct 101 is a backup air duct structure. When the temperature inside the back panel is too high, the fan 200 is activated to perform active cooling. The central air duct 101 utilizes the connection and cooperation between the peripheral sub-air ducts 103 and the branch air ducts 102. The air entering from the outer port of the sub-air duct 103 is guided to the central air duct 101 through the branch air duct 102. The central air duct 101 and the sub-air duct 103 are connected to the fresh air duct through their outer ports, realizing the intake and exhaust air cooling operation.
