[0006] Compared with the prior art, the technical effect achieved by adopting this technical solution is as follows: in combination with the actual installation situation of the first shell and the second shell, when the first shell is installed to the second shell, the first enclosure frame located on the first shell and the second enclosure frame located on the second shell cooperate with each other and fit together to form a stop structure. Specifically, the second enclosure frame is nested into the first enclosure frame, and the accommodation space formed between the two is the first accommodation chamber. The enclosure walls of the first enclosure frame and the second enclosure frame are staggered and fit together to form an upper and lower staggered retaining wall structure, which is the stop structure. The first accommodation chamber is connected to the external environment space. The stop structure can separate the first accommodation chamber from the second accommodation chamber, preventing dust accumulation and water ingress in the second accommodation chamber, thereby causing damage to the electronic components in the second accommodation chamber and causing a short circuit. Compared with separately setting a stop plate to prevent dust accumulation and water ingress, this technical solution rationally utilizes the mutual cooperation between the first enclosure frame and the second enclosure frame, acting as both the enclosure wall of the first accommodation chamber and the stop structure to prevent dust accumulation and water ingress, thereby achieving rational utilization of the enclosure frame, eliminating the need for additional stop plates, and saving material usage.

[0007] In one example of the present invention, the airflow duct includes a first channel provided in the first shell, connecting the first enclosure frame with the first accommodating chamber, forming a first channel opening at the connection point, and the second enclosure frame is attached to the side of the first channel opening close to the second accommodating chamber to prevent the first channel opening from being blocked and hindering the passage of airflow; and / or, the airflow duct includes a second channel provided in the second shell, connecting the second enclosure frame with the first accommodating chamber.

When the length of the first rib is too short or flush with the edge of the second shell frame, water droplets are likely to gather in the gap formed by the mutual fit of the frame walls of the first shell and the second shell, and then penetrate into the gap into the interior of the shell, damaging the electronic components placed in the second accommodating chamber.

[0015] In an embodiment of the present invention, the first shell is provided with a plurality of first drainage holes; the first drainage holes are provided at positions of the first shell corresponding to the first accommodating chamber.

[0016] Compared with the existing technology, the technical effect achieved by adopting this technical solution is: by setting the first drainage hole at the position of the first shell corresponding to the first accommodating chamber, when water accumulates in the first accommodating chamber, the water can be discharged from the first drainage hole.

[0017] In an embodiment of the present invention, the first drainage hole is provided in the first enclosure; the first enclosure cooperates with the second enclosure on one side of the first shell, and the first drainage hole is provided on the other side.

[0018] Compared with the existing technology, the technical effect achieved by adopting this technical solution is: by arranging the first drainage hole on the first frame of the first accommodating chamber, the accumulated water can be more easily discharged from the first accommodating chamber when the vehicle-mounted device is installed at an angle.

[0020] Compared with the existing technology, the technical effect achieved by adopting this technical solution is: by providing a heat dissipation boss, the heat generated by the electronic components in the second accommodating chamber is transferred to the first shell and the second shell through the heat dissipation boss.

[0021] In one embodiment of the present invention, the air duct is provided with a plurality of heat dissipation fins, and the heat dissipation fins are used to transfer heat to the external environment space.

[0022] Compared with the existing technology, the technical effect achieved by adopting this technical solution is: by arranging multiple heat dissipation fins in the air flow duct, the heat conducted to the first shell and the second shell is further conducted to the heat dissipation fins, and the air flow enters from the first accommodating chamber, flows to the first channel and the second channel, and transfers the heat on the heat dissipation fins to the external environment space.

[0023] In an embodiment of the present invention, one end of the heat dissipation fin is close to the first accommodation chamber, and the other end is far away from the first accommodation chamber; and a plurality of heat dissipation fins are arranged in parallel.

By setting a stop structure in the first accommodating chamber 300 and the second accommodating chamber 400, the first accommodating chamber 300 and the second accommodating chamber 400 are separated to prevent dust accumulation and water ingress in the second accommodating chamber 400, which may cause damage to the electronic components in the second accommodating chamber 400 and cause a short circuit in the electronic components.

[0038] See also Figure 1The airflow duct includes a first channel 112 provided in the first shell 100, connecting the first enclosure 110 with the first accommodating chamber 300, forming a first channel opening 113 at the connection point, and the second enclosure 210 is attached to the side of the first channel opening 113 close to the second accommodating chamber 400 to prevent the first channel opening 113 from being blocked and hindering the passage of air; and / or, the airflow duct includes a second channel 211 provided in the second shell 200, connecting the second enclosure 210 with the first accommodating chamber 300.

[0039] The airflow duct can connect the first accommodating chamber 300 and the external environment space. Specifically, there are three situations. For example, the airflow duct includes a first channel 112 provided in the first shell 100, connecting the first frame 110 with the first accommodating chamber 300, and forming a first channel opening 113 at the connection point. The second frame 210 is attached to the side of the first channel opening 113 close to the second accommodating chamber 400 to prevent the first channel opening 113 from being blocked and hindering the airflow; for another example, the airflow duct includes a second channel 211 provided in the second shell 200, and the second channel 211 is connected to the first accommodating chamber 300; for another example, the first channel 112 and the second channel 211 exist at the same time and are connected to the first accommodating chamber 300.

The first housing 100 and the second housing 200 are joined together on all sides to form staggered retaining walls, creating an enclosed space within which the first accommodating chamber 300 and the second accommodating chamber 400 reside. This cooperation and the enclosed space between the first housing 100 and the second housing 200 enhance the tightness of the assembly of the first housing 100 and the second housing 200, making it less likely for water to enter the housings through the gap between the first housing 100 and the second housing 200, and subsequently enter the second accommodating chamber 400, potentially damaging the electronic components.

When water droplets fall on the second shell 200, the water can flow away along the first ribs 212. When the length of the first ribs is too short or flush with the edge of the second shell frame, the water droplets are likely to gather in the gap formed by the mutual adhesion of the frame walls of the first shell 100 and the second shell 200, and then penetrate into the gap into the interior of the shell, damaging the electronic components placed in the second accommodating chamber 400.
