Description

Technical Field

[0001] The utility model belongs to the technical field of automobiles, and in particular relates to an automobile electrical appliance box with high safety. Background Art

[0002] The electrical box on a car is generally placed in the cab and the engine compartment. The electrical box is used to store fuses, relays, turn signal flashers, preheating relays, etc. The automotive electrical box is mainly used for the distribution and transmission of power for the entire vehicle. It is the core component of the vehicle's power distribution system and is of great significance to the entire vehicle's electrical system. As people's requirements for automobile safety, comfort, economy and emissions increase, the electrical functions of the entire vehicle are becoming more and more complex, and the heat emitted by the electrical functions is also increasing.

[0003] In the Chinese patent with publication number CN210212283U, a high-safety automotive electrical box is mentioned. The existing automotive electrical boxes are no longer able to adapt to higher-level electrical systems and do not have a suitable heat dissipation structure, which leads to an increase in temperature inside the electrical box. The increase in electrical heat can cause system failures. Minor failures can cause system short circuits, and the car cannot drive normally. In serious cases, it may affect the safety of car driving. A high-safety automotive electrical box includes an electrical box, a cooling fan and electronic components. The electrical box consists of an upper box cover and a lower box body, which is characterized in that a dust cover is fixedly installed on the upper surface of the upper box cover, and the lower part of the upper box cover is fixedly connected to the lower box body. The cooling fan is fixedly installed inside the lower box body. The electronic components are above the cooling fan. The operation of the cooling fan drives airflow to blow toward the electronic components above. The flowing airflow accelerates the heat dissipation of the entire electronic components, so that the electronic components are in a normal temperature state.

[0004] Although the above-mentioned device keeps the electronic components in the electrical box in normal working condition at all times by providing a cooling fan, the heat dissipation mechanism of the device not only occupies the space for installing the electronic components, reducing the space utilization rate, but also makes it very easy for external dust to enter the interior of the electrical box during use, thereby affecting the service life of the internal electronic components. Utility Model Content

[0005] The purpose of the utility model is to provide a highly safe automobile electrical appliance box to solve the problems existing in the prior art.

The connecting groove 19 is used to connect the lower end of the guide box 21 and the upper end of the connecting pipe 32.

[0030] In this embodiment, the guide box 21 is connected to the upper shell 11 and the upper docking ring 13 by bolts and there are sealing gaskets at the connections. Similarly, the water cooling box 31 is connected to the lower shell 15 and the lower docking ring 17 by bolts and there are sealing gaskets at the connections.

[0031] In a further embodiment, a lower through groove 16 is formed on a side of the lower shell 15 close to the water cooling box 31 , and the lower through groove 16 is connected to the lower end of the connecting pipe 32 .

[0032] In this embodiment, a rectangular groove is formed on the inner side of the lower through slot 16 of the lower shell 15 for diffusing the cooled air.

[0033] In a further embodiment, guide fans 22 are evenly arranged inside the guide box 21 and are used to guide the direction of airflow.

[0034] In this embodiment, a connector is provided on the outside of the guide box 21 for connecting to an external power supply and controller through a line to operate the guide fan 22. When the guide fan 22 is operating, the airflow will be guided to the inside of the connecting tube 32, thereby dissipating heat inside the box body mechanism 1.

[0035] In a further embodiment, an upper docking groove 14 is provided on the side of the upper shell 11 and the upper docking ring 13 away from the guide box 21, and a lower docking groove 18 is provided on the side of the lower shell 15 and the lower docking ring 17 away from the water cooling box 31, and the bottom port of the upper docking groove 14 fits with the top port of the lower docking groove 18.

[0036] In this embodiment, the opening of the upper docking groove 14 located inside the upper shell 11 is flush with the upper through groove 12, and the opening of the lower docking groove 18 located inside the lower shell 15 is flush with the lower through groove 16, thereby facilitating the flow of air.

[0037] In a further embodiment, a side of the water cooling box 31 away from the box body mechanism 1 is embedded with evenly arranged heat dissipation spines 33 , and a side of the water cooling box 31 away from the box body mechanism 1 is provided with two docking joints 34 .

[0038] In this embodiment, the docking joint 34 is used to facilitate adding or reducing the coolant inside the water cooling box 31; the heat dissipation ridge 33 is a heat conducting component used to dissipate the heat of the coolant in the water cooling box 31 to the outside.

The circuit board is used to plug in electronic components in the existing automobile electrical box.

[0041] The working principle of this utility model is as follows:

[0042] When the relays and other devices in the car are plugged into the circuit board inside the box body mechanism 1, and the entire box body mechanism 1 is installed inside the car, the guide fan 22 in the guide box 21 is connected through a line, so that it guides the airflow inside the upper shell 11, so that the airflow on the circuit board passes through the upper through groove 12, the inside of the guide box 21, the connecting groove 19 and the connecting pipe 32 in turn to reach the inside of the lower shell 15 below the power board, and the air originally inside the lower shell 15 will pass through the lower docking groove 18 and the upper docking groove 14 in turn to reach the inside of the upper shell 11, thus circulating back and forth, and when the airflow passes through the inside of the connecting pipe 32, it will be cooled by the coolant injected into the water cooling box 31. Since the guide box 21 and the water cooling box 31 are respectively installed on one side of the upper shell 11 and the lower shell 15 by bolts, the electronic components installed inside the box body mechanism 1 can be cooled without occupying the internal space of the box body mechanism 1.

[0043] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
