[0010] Further, a plurality of struts are arranged on the bottom surface of the bottom box parallel to the top cover. The conversion module is fixed on the plurality of struts and forms a heat dissipation cavity with the bottom of the inner cavity of the bottom box.

[0011] Further, a heat dissipation seat is also arranged on the bottom surface of the bottom box.

[0012] Further, inclined sliding grooves for installing the air guide plate are provided on the opposite side walls of the bottom box.

[0013] Further, one side edge of the upper cover is bent to form the air guide plate.

[0014] Further, the opposite side edges of the upper cover are bent and joined together to form the air guide plate.

When an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be an intermediate element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are only for the purpose of illustration and do not represent the only implementation.

[0026] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field to which the present utility model belongs. The terms used in the description of the present utility model are only for the purpose of describing specific embodiments and are not intended to limit the present utility model. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0027] As Figures 1 to 2 shown in the vehicle-machine interconnection conversion box, it includes: an outer housing 1 and a conversion module 2 arranged inside the outer housing 1; the outer housing 1 includes a bottom box 11 and a top cover 12 arranged on the top of the bottom box 11. An air inlet 1a is provided on one side of the bottom box 11, and a wind guide plate 13 is provided in the bottom box 11 below the top cover 12. The wind guide plate 13 is inclined upward in a direction away from the air inlet 1a to form an air flow channel, and an air outlet 1b is provided on the top cover 12 at the outlet of the air flow channel.

[0028] Through the setting of the wind guide plate 13 in the present utility model, external gas can be introduced into the inside of the bottom box 11 through the air flow channel and discharged through the air outlet 1b to form an air flow cycle. Moreover, due to the inclined design of the wind guide plate 13, the flow rate of the gas at the air outlet 1b can be increased, so as to quickly take away the heat generated by the internal components and improve the heat dissipation efficiency.

[0029] In the present utility model, the conversion module 2 includes a control circuit board and a first interface 21 and a second interface 22 electrically connected to the control circuit board; and the first interface 21 is connected to the vehicle body, and the second interface 22 is connected to the mobile phone. In the design process of the conversion module 2, the number of the first interface 21 and the second interface 22 is not limited to one, and the number of interfaces can be increased according to the connection requirements.

[0030] In a preferred embodiment, the upper cover 12 is slidably connected above the bottom case 11; the bottom case 11 and the upper cover 12 are provided with mutually cooperating chutes and protrusions, allowing the user to easily remove the upper cover 12 from the bottom case 11, facilitating the assembly, maintenance or replacement of internal components.

[0031] To further enhance the heat dissipation effect, a number of struts 111 are provided on the bottom surface of the bottom case 11 parallel to the upper cover 12. The conversion module 2 is fixed on the number of struts 111 and forms a heat dissipation cavity with the bottom of the inner cavity of the bottom case 11.

[0032] Based on the above embodiment, a heat dissipation seat 112 is further provided on the bottom surface of the bottom case 11, increasing the contact area with the circuit board and improving the heat dissipation efficiency.

[0033] In a preferred solution, inclined chutes 11a for installing the air guide plate 13 are provided on the opposite side walls of the bottom case 11. By setting the air guide plate 13 and the upper cover 12 as a split structure, different-width air guide plates 13 can be replaced according to the position of the air outlet 1b and different heat dissipation requirements, without the need to replace the entire upper cover 12, reducing the maintenance and replacement costs.

[0034] In the present utility model, both the air inlet 1a and the air outlet 1b adopt a grid structure. The grid-like design helps to evenly distribute the incoming and outgoing airflows, reducing the turbulent flow and eddy currents, improving the heat dissipation efficiency. In addition, to a certain extent, it allows the outside air to enter, while also preventing larger dust particles from entering the bottom case 11.

[0035] In the present utility model, a plurality of through holes at the air outlet 1b are inclined along the air guiding direction of the air guide plate 13. The inclined through holes help the gas to flow out more smoothly, reducing the retention of the gas at the air outlet 1b.

[0036] In another preferred solution, as Figure 3 and Figure 4 shown, one side edge of the upper cover 12 is bent to form the air guide plate 13, or both side edges of the upper cover 12 are bent and joined relatively to form the air guide plate 13. In this solution, the upper cover 12 and the air guide plate 13 adopt an integral structure, reducing the need for additional components and simplifying the assembly process. The side wall connecting the upper cover 12 and the air guide plate 13 can increase the heat dissipation surface area and improve the heat dissipation efficiency.

[0037] Those skilled in the art of this industry should understand that the present utility model is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principle of the present utility model. Without departing from the spirit and scope of the present utility model, the present utility model will have various changes and improvements, and these changes and improvements all fall within the scope of the present utility model claimed. The scope of protection claimed by the present utility model is defined by the appended claims and their equivalents.
