The present invention relates to a block for automobiles.

In automobiles, automobile blocks that control the supply of power to various electrical components are used. Relays, fuses, resistors, etc. are installed in the automotive block to perform various functions. For example, an automobile block may be located between a battery and a motor driving device to be in charge of power connection, or may be located between an external power source and a battery to perform functions related to battery charging.

Blocks for automobiles can perform various functions, and one block may perform a plurality of functions. For example, it is possible to control the charging of the battery by transferring power from the battery to electric components or by having a normal charging function and a rapid charging function respectively in charging the battery.

However, not all users want all these features in a car. Therefore, in order to satisfy the needs of various users, it is necessary to separate the functions of the automotive block to create a vehicle block.

For example, in the prior art, an essential component for performing a function absolutely necessary for a single block and a component for performing an optional function that is selectively used are disposed in one housing.

In the present invention, the essential block housing may have a first mounting plate and a second mounting plate orthogonally connected to each other, and the essential block cover may have a first cover plate and a second cover plate orthogonally connected.

In the present invention, side plates may be provided to be simultaneously connected to both ends of the first mounting plate and the second mounting plate of the essential block housing, and simultaneously to both ends of the first cover plate and the second cover plate of the essential block cover. A side plate may be provided to be connected.

In the present invention, the first mounting plate and the second mounting plate may be formed by protruding terminal blocks in which external connection parts for connecting to the outside are located.

In the present invention, a space partitioned by a partition wall may be formed in the first mounting plate, and a component may be erected and installed in the space so that an outer surface having a relatively small area among outer surfaces is seated on the first mounting plate.

In the present invention, a mounting bracket may be installed on the first mounting plate, a current sensor is installed in the installation space of the mounting bracket, and a connector installation end may be formed on one side of the mounting bracket to ensure electrical connection with the outside. connectors can be installed.

The automobile block according to the present invention may have at least one or more of the following effects.

In the present invention, the essential block part and the optional block part can be configured as separate housings and separated, and the essential block part and the optional block part can be electrically connected to each other through a bus bar assembly. The essential block unit can manage power supply and charge to the battery, and the selection block unit can mount, for example, a rapid charging circuit. Therefore, in a vehicle that does not need to use the rapid charging function, it is possible to manage power supply and battery charging by using the essential block unit without installing the selection block unit. Therefore, in the case of using only the essential block parts without using the optional block parts, the production cycle time can be reduced and the assembly of wrong specifications can be prevented.

In order to reduce fuel efficiency in the design of automobiles, weight reduction and miniaturization are required. For example, the space in which blocks are installed is pre-determined, and automobile blocks are installed in that space. If the automobile blocks are separated into essential blocks and optional blocks, only essential blocks can be used. Since it is possible not to install the part, it is possible to save the weight and space required for the selection block part.

In the present invention, the essential block part and the optional block part are electrically connected to the bus bar assembly, and the selection block part is used only when required as a vehicle option. In order to achieve such a configuration, it is necessary to more efficiently arrange components installed in the essential block part or the selective block part. In the present invention, the essential block housing and the optional block housing each have a first mounting plate and a second mounting plate orthogonal to each other, and parts are mounted thereto. The surface having a relatively small area of the part is the first mounting plate I made it to be seated on the second mounting plate. Therefore, the arrangement of components in the essential block housing and the optional block housing is efficient, and minimization of the space occupied by the essential block portion and the optional block portion is possible.

And, in the present invention, the current sensor and the connector are simultaneously mounted on the mounting bracket mounted on the essential block housing. Therefore, the inner space of the essential block housing can be divided and used more effectively. In other words, since the connector is mounted on one side of the mounting bracket where the current sensor is installed, there is an effect of not separately using the component mounting area of the essential block housing for mounting the connector.

And, in the present invention, in the design of the bus bar used in the essential block part and the optional block part, the length of the bus bar and the number of bending are minimized by adjusting the position of the terminal block for connection to the outside and the installation position of the parts made to do Therefore, it is easier to manufacture the bus bar used in the essential block part and the optional block part, and there is an effect that the length and size of the bus bar can be miniaturized.

In addition, in the present invention, the terminal cover is placed on the first assembly of the bus bar assembly. Therefore, when the first assembly of the bus bar assembly is used, there is also an effect that can more easily and reliably insulate the external connection portion for external connection in the essential block portion and the optional block portion.
