Problems solved by technology

[0002] At present, most of the rear starting controls of urban buses and tourist buses are assembled on-site from parts, and the insurance adopts a fusible link, but the fusible link is not very effective as an insurance, and there is no protection for the second start, but this All kinds of electrical components are placed in the battery compartment without protection, and the electronic components will be corroded by the electrolyte after a long time, which will cause component aging, circuit failure, difficulty in starting, etc.

Embodiment

[0020] Such as figure 1 As shown, a passenger car electrical control box includes a housing 1 , a mounting board, and a printed circuit board. The printed circuit board is fixed on the mounting board, and the printed circuit board is fixed in the housing 1 .

[0021] The printed circuit board is provided with a starting power switch 2, a power switch 3, a five-pin relay 4, a diode group 5, a delay relay 6, a preheating relay 10, a starting relay 9, and a fuse module. Described five pin relay 4 is provided with 3. The fuse module includes a low-power fuse set 7 and a high-power fuse set 8 . The power switch 3 is a full plastic case switch with a rated current of 300A. When the starter circuit is overcurrent or overheated, the switch will forcefully stop starting and send an overheating and overcurrent signal to the instrument panel.

[0022] The housing 1 is provided with a honeycomb insert 11 . The shell 1 is a dust-proof all-plastic shell and is provided with a transparent...

Abstract

The invention relates to an electric control box for buses. The electric control box comprises a casing, a mounting plate, and a printed circuit board, wherein the printed circuit board is fixed on the mounting plate and the mounting plate is fixed in the casing. The printed circuit board is provided with a power-on switch, a power switch, a five-point relay, a diode group, a time-delay relay, a preheat relay, a starting relay, and a fuse module. Compared with the prior art, the electric control box of the invention has the advantages of ability of realizing functions of overheating protection and over-current protection, good safety, small size, and the like.

Description

technical field [0001] The invention relates to an electric appliance control box, in particular to an electric appliance control box for passenger cars. Background technique [0002] At present, most of the rear starting controls of urban buses and tourist buses are assembled on-site from parts, and the insurance adopts a fusible link, but the fusible link is not very effective as an insurance, and there is no protection for the second start, but this All kinds of electrical components are placed in the battery compartment without protection, and the electronic components will be corroded by the electrolyte after a long time, resulting in component aging, circuit failure, and difficulty in starting. Contents of the invention [0003] The object of the present invention is to provide a passenger car electrical control box capable of overheating and overcurrent protection, high in safety, and small in size in order to overcome the defects of the above-mentioned prior art. ...
