[0020] Traditional vehicle host devices have standardized dimensions: if they are integrated into a single-DIN configuration, the dimensions are 178*130*50; if they are integrated into a double-DIN configuration, the dimensions are 220*150*70. However, when in-vehicle navigation systems have more functions, the vehicle host device typically adopts an integrated double-DIN configuration. Due to the presence of heat dissipation structures, other internal components of the vehicle host device are difficult to adjust. Configuration requires the addition of two or more PCBs, sockets to connect the two or more PCBs, and corresponding heat dissipation structures. This results in a relatively redundant overall host device structure and high costs.

[0021] See also Figures 1 to 4 , Figure 1 This is a front schematic structural diagram of an independent host heat dissipation device of the present utility model; Figure 2 This is a side schematic structural diagram of an independent host heat dissipation device of the present utility model; Figure 3 This is a schematic structural exploded diagram of a stand-alone host heat dissipation device of the present invention; Figure 4 This is a schematic structural diagram of the frame of a vehicle according to the present invention.

[0022] like Figure 1-3 As shown, an embodiment of the present invention provides an independent host heat dissipation device 1, which is applied to a host device 40 of a vehicle 2, and includes a heat dissipation structure 10, a PCB board 20 and a bracket 30; the heat dissipation structure 10 is connected to a PCB board 20; a PCB board 20 is connected to the bracket 30 and is also connected to the host device 40 for communication; the bracket 30 is connected to the screen 50 of the vehicle 2; wherein, the heat dissipation structure 10 is used to dissipate heat for a PCB board 20, a PCB board 20 is used to communicate with the host device 40, and the bracket 30 is used to fix the heat dissipation structure 10 and a PCB board 20 at the position of the screen 50 of the vehicle 2.

[0023] In this embodiment, if Figure 1-3 As shown, the host device 40 refers to the vehicle 2 host used in the vehicle navigation system, which can be used on various types of vehicles 2. For example, the vehicle 2 can be a car, a truck, a bus, a trailer, etc., that is, the host device 40 is configured in the vehicle navigation system of the vehicle 2 such as a car, a truck, a bus, a trailer, etc.

[0024] Compared with traditional heat dissipation technology, the present invention separates the heat dissipation structure 10 from the host device 40 of the vehicle 2, that is, the heat dissipation structure 10 is set independently. In this way, there is no space restriction. The heat dissipation structure 10 can be configured with a larger PCB board 20 for communication connection with the host device 40 of the vehicle 2, and combined with the bracket 30, thereby simplifying the internal structure of the host device 40 and reducing costs.

[0025] The material of the heat dissipation structure 10 can be aluminum alloy, etc.; the heat dissipation structure 10 is a hollow structure, and heat conductive materials such as heat dissipation oil and heat dissipation silicone can be used for conduction between the heat dissipation structure 10 and a PCB board 20, so as to conduct heat from a PCB board 20 to the heat dissipation structure 10 for heat dissipation. Specifically, the heat dissipation silicone transfers the heat generated by a PCB board 20 to the heat dissipation fins on the heat dissipation structure 10 through the heat conductive material, and the heat dissipation fins on the heat dissipation structure 10 transfer the heat to the outside of the vehicle 2.

[0026] From the above embodiments, it can be seen that the heat dissipation structure 10 is independently provided and connected to a PCB board 20, thereby achieving a simple structure, convenient installation, and reduced cost.

[0027] In one embodiment, if Figure 1-3 As shown, the upper surface of the heat dissipation structure 10 is provided with a first heat dissipation fin 11, a second heat dissipation fin 12 and a third heat dissipation fin 13; the first heat dissipation fin 11 and the second heat dissipation fin 12 are spliced ​​with each other, and the second heat dissipation fin 12 and the third heat dissipation fin 13 are spliced ​​with each other.

[0028] In this embodiment, if Figure 1-3 As shown, the first heat sink fins 11 and the second heat sink fins 12 can be spliced ​​together. The length ratio of the spliced ​​fins or the smoothness of the connection (the tilt angle at the connection) can be adaptively set according to the height or density of components requiring heat dissipation on a PCB board 20. Similarly, the second heat sink fins 12 and the third heat sink fins 13 can be spliced ​​together. The length ratio of the spliced ​​fins or the smoothness of the connection (the tilt angle at the connection) can be adaptively set according to the height or density of components requiring heat dissipation on a PCB board 20.

[0029] It should be noted that the first heat dissipation fin 11 can also be spliced ​​with the third heat dissipation fin 13. The length ratio of the splicing or the smoothness of the connection (the tilt angle of the connection) can be adaptively set according to the height or density of the components that need heat dissipation on a PCB board 20.

[0030] Each heat dissipation fin formed by splicing each other is parallel to each other, and a plurality of heat dissipation fins are provided, and the fin height, fin length and fin density are positively correlated with the height or density of the components that need heat dissipation on a PCB board 20, and can be specifically set according to actual conditions; each heat dissipation fin is wavy, used to dissipate heat for a PCB board 20, and can better conduct heat to the air away from a PCB board 20, so as to transfer it to the outside of the vehicle 2.

[0031] The side surface of the heat dissipation structure 10 is provided with a plurality of heat dissipation holes 15, and the plurality of heat dissipation holes 15 are used to increase the heat dissipation effect on a PCB board 20. Specifically, Figure 3 As shown, the upper surface of the heat dissipation structure 10 is provided with a plurality of heat dissipation holes 15, and correspondingly, the lower surface of the heat dissipation structure 10 is also provided with a plurality of heat dissipation holes 15. It should be noted that the plurality of heat dissipation holes 15 on the lower surface of the heat dissipation structure 10 are not shown in the drawing due to angle problems.

[0032] Through the above embodiment, the first heat dissipation fin 11 and the second heat dissipation fin 12 are spliced ​​with each other, and the second heat dissipation fin 12 and the third heat dissipation fin 13 are spliced ​​with each other. In this way, each heat dissipation fin formed by splicing each other can be better adapted to a PCB board 20, thereby improving the adaptability of the device.

[0033] In one embodiment, if Figure 1-3 As shown, the plane height of the first heat dissipation fins 11 is greater than the plane height of the second heat dissipation fins 12 , and the plane height of the second heat dissipation fins 12 is greater than the plane height of the third heat dissipation fins 13 .

[0034] In this embodiment, if Figure 1-3 As shown, the plane height of the first heat dissipation fin 11 refers to the vertical height from the top of the first heat dissipation fin 11 to the plane where the lower surface relative to the upper surface of the heat dissipation structure 10 is located, that is, the plane height of the first heat dissipation fin 11 is the vertical height from the top of the first heat dissipation fin 11 to the plane away from the first heat dissipation fin 11; the plane height of the second fin refers to the vertical height from the top of the second heat dissipation fin 12 to the plane where the lower surface relative to the upper surface of the heat dissipation structure 10 is located, that is, the plane height of the second fin is the vertical height from the top of the second heat dissipation fin 12 to the plane away from the second heat dissipation fin 12; the plane height of the third fin refers to the vertical height from the top of the third heat dissipation fin 13 to the plane where the lower surface relative to the upper surface of the heat dissipation structure 10 is located, that is, the plane height of the third fin is the vertical height from the top of the third heat dissipation fin 13 to the plane away from the third heat dissipation fin 13.

[0035] The plane height of the first heat dissipation fin 11 is greater than the plane height of the second heat dissipation fin 12, and the plane height of the second heat dissipation fin 12 is greater than the plane height of the third heat dissipation fin 13. In this way, the plane height of the heat dissipation fins at the corresponding position can be adaptively set according to the height or density of the components that need heat dissipation on a PCB board 20, which reduces the occupied space, simplifies the structural design, and saves costs.

[0036] In one embodiment, if Figure 1-3 As shown, the thickness of the first heat dissipation fins 11 , the second heat dissipation fins 12 and the third heat dissipation fins 13 are all 3 mm.

[0037] In this embodiment, if Figure 1-3 As shown, the thickness of the first heat dissipation fins 11, the second heat dissipation fins 12 and the third heat dissipation fins 13 are all set to 3 mm, which effectively increases the heat dissipation area of ​​the heat dissipation structure 10, and combined with the aluminum alloy material of the heat dissipation structure 10, thereby improving the heat dissipation efficiency.

[0042] The first threaded hole 141, the second threaded hole 142, the third threaded hole 143, and the fourth threaded hole 144 are distributed on the edge portion of the side surface of the heat dissipation structure 10, that is, the first threaded hole 141, the second threaded hole 142, the third threaded hole 143, and the fourth threaded hole 144 are protruding structures that can be set on the left surface and the right surface of the heat dissipation structure 10; the fifth threaded hole 145 is set on the upper surface of the heat dissipation structure 10; in this way, the screw is passed through the first threaded hole 141, the second threaded hole 142, the third threaded hole 143, the fourth threaded hole 144, and the fifth threaded hole 145 in sequence, and the heat dissipation structure 10, a PCB board 20, and the bracket 30 are fixedly connected using matching screws to better perform heat dissipation and improve the stability of the device.

[0044] In this embodiment, if Figure 1-3 As shown, the first fixing holes 146 and the second fixing holes 147 are distributed on the edge of the side surface of the heat dissipation structure 10. Specifically, the first fixing holes 146 and the second fixing holes 147 are raised structures provided on the lower surface of the heat dissipation structure 10. The first fixing holes 146 and the second fixing holes 147 can be connected to the vehicle 2 by snapping or screwing. The specific configuration can be determined according to actual conditions. The first fixing holes 146 and the second fixing holes 147 are used to securely connect to the vehicle 2, ensuring a stable connection and improving stability.

In this way, there is no space limitation, and a larger PCB board 20 can be configured to communicate with the host device 40 of the vehicle 2, thereby simplifying the internal structure of the host device 40 and reducing costs.

[0049] The material of the heat dissipation structure 10 can be aluminum alloy, etc.; the heat dissipation structure 10 is a hollow structure, and heat conductive materials such as heat dissipation oil and heat dissipation silicone can be used for conduction between the heat dissipation structure 10 and a PCB board 20, so as to conduct heat from a PCB board 20 to the heat dissipation structure 10 for heat dissipation. Specifically, the heat dissipation silicone transfers the heat generated by a PCB board 20 to the heat dissipation fins on the heat dissipation structure 10 through the heat conductive material, and the heat dissipation fins on the heat dissipation structure 10 transfer the heat to the outside of the vehicle 2.
