Abstract

A hydraulic block of an electronic braking device for a vehicle may include: a block body including a controller mounting part to which an electronic control unit (ECU) is coupled and a motor mounting part to which a motor is coupled; an input port part disposed closer to the controller mounting part between the controller mounting part and the motor mounting part; an output port part disposed closer to the motor mounting part between the controller mounting part and the motor mounting part; and a hydraulic circuit part formed in the block body so as to extend from the input port part to the output port part, and housing a valve controlled by the ECU.

First claim

What is claimed is:

1. A hydraulic block of an electronic braking device for a vehicle, comprising:
a block body including a controller mount configured to couple an electronic control unit (ECU) and a motor mount configured to couple a motor;
an input port part disposed closer to the controller mount between the controller mount and the motor mount;
an output port part disposed closer to the motor mount between the controller mount and the motor mount; and
a hydraulic circuit formed in the block body and configured to extend from the input port part to the output port part, and the hydraulic circuit including a valve configured to be controlled by the ECU,
wherein the input port part comprises:
a main braking port comprising a first main braking port and a second main braking port, each configured to be connected to an output line of a main braking device; and
a master cylinder port configured to be connected to an output line of a master cylinder, and disposed between the first main braking port and the second main braking port.

2. The hydraulic block of claim 1 , wherein the input port part is configured to be connected to an output line of a main braking device, and is disposed closer to the output line of the main braking device than the output port part, and
the output port part is configured to be connected to a hydraulic brake line for individually adjusting a wheel.

3. The hydraulic block of claim 1 , wherein the motor mount and the controller mount are disposed on a front surface and a rear surface of the block body, respectively, and
the input port part is disposed on a top surface of the block body, which has a smaller area than the front and rear surfaces of the block body.

4. The hydraulic block of claim 3 , wherein the input port part comprises a plurality of input ports arranged on the top surface of the block body while forming a first line, and
the output port part comprises a plurality of output ports arranged on the top surface of the block body in parallel to the input port part, while forming a second line.

5. The hydraulic block of claim 1 , wherein the hydraulic circuit comprises:
a first chamber connected to the input port part, and housing a first valve inserted through the controller mount;
a chamber connection flow path extending downward from the first chamber;
a second chamber connected to the chamber connection flow path, and housing a second valve inserted through the controller mount; and
an extended flow path extending upward from the second chamber to the output port part.

6. The hydraulic block of claim 5 , wherein the first chamber comprises:
a first input chamber connected to the bottom of the input port part so as to communicate with the input port part, such that fluid is introduced into the first valve; and
a first output chamber connected to the first input chamber to switch a flow direction of the fluid to a lateral direction.

7. The hydraulic block of claim 5 , wherein the second chamber comprises:
a second input chamber connected to the bottom of the chamber connection flow path so as to be extended in a lateral direction, such that fluid is introduced into the second valve; and
a second output chamber connected to the second input chamber to switch a flow direction of the fluid to a downward direction.

8. An electronic braking device for a vehicle, comprising:
a main braking device configured to brake a vehicle using hydraulic pressure; and
an auxiliary braking device configured for redundancy of vehicle braking, and including a hydraulic block having one side connected to an output line of the main braking device and the other side connected to a hydraulic brake line for individually adjusting a wheel,
wherein the hydraulic block comprises:
a block body including a controller mount configured to couple an ECU and a motor mount configured to couple a motor;
an input port part disposed closer to the controller mount between the controller mount and the motor mount, and connected to the output line of the main braking device;
an output port part disposed closer to the motor mount between the controller mount and the motor mount, and connected to the hydraulic brake line; and
a hydraulic circuit formed in the block body so as to extend from the input port part to the output port part, and
wherein the input port part comprises:
a main braking port comprising a first main braking port and a second main braking port, each connected to the output line of the main braking device; and
a master cylinder port connected to an output line of a master cylinder, and disposed between the first main braking port and the second main braking port.

9. The electronic braking device of claim 8 , wherein the input port part is disposed closer to the output line of the main braking device than the output port part.

10. The electronic braking device of claim 8 , wherein the motor mount and the controller mount are disposed on a front surface and a rear surface of the block body, respectively, and
the input port part is disposed on a top surface of the block body, which has a smaller area than the front and rear surfaces of the block body.

11. The electronic braking device of claim 10 , wherein the input port part comprises a plurality of input ports arranged on the top surface of the block body while forming a first line, and
the output port part comprises a plurality of output ports arranged on the top surface of the block body in parallel to the input port part, while forming a second line.

12. The electronic braking device of claim 8 , wherein the hydraulic circuit comprises:
a first chamber connected to the input port part, and housing a first valve inserted through the controller mount;
a chamber connection flow path extending downward from the first chamber;
a second chamber connected to the chamber connection flow path, and housing a second valve inserted through the controller mount; and
an extended flow path extending upward from the second chamber to the output port part.
