Problems solved by technology

When implementing the electrical connection between the above-mentioned circuit board and the electromagnetic clutch, if conventional wires and cables are used for connection, since the wires and cables are flexible wires, it is not easy to shape during installation, which increases the difficulty of assembly
If the cable and the circuit board are connected by soldering, the process is not only time-consuming, but also has problems such as missing soldering and virtual soldering, which reduces the reliability of the electrical connection
[0004] For the above problems, no effective solution is given in the prior art. The present invention has made further research on this, and improved the electrical connection structure between the circuit board and the electromagnetic clutch to solve the above problems

Embodiment 1

[0071] refer to figure 1 , 2 , the actuator of the electromechanical brake proposed in Embodiment 1 of the present invention includes: a housing 100; and a motor housed in the housing 100, the motor includes a motor shaft 400; The clutch, the electromagnetic clutch is used to lock or release the motor shaft 400 ; and the circuit board 700 housed in the housing 100 ; and the electrical connector 900 is used to establish an electrical connection between the electromagnetic clutch and the circuit board 700 . Wherein, the motor includes a motor shaft 400, a motor stator 300 and a motor rotor 200. The motor rotor 200 is fixedly connected to the motor shaft 400. When the motor rotor 200 rotates relative to the motor stator 300, it can synchronously drive the motor shaft 400 to rotate to realize braking torque output. Although an inner rotor motor is used in this embodiment for illustration, it is not limited thereto, and the motor of the actuator can be any type of motor that uses ...

Embodiment 2

[0078] refer to Figure 4 , 5 The difference between this embodiment and Embodiment 1 is that the electrical connector 900 includes a male connector 920 disposed on the circuit board 700 and a female connector 930 disposed on the stator 500 that are plugged and connected to each other. Said: the electrical connector 900 is a male connector 920 and a female connector 930 designed in pairs, the male connector 920 is installed on the circuit board 700, and the female connector 930 is installed on the stator 500. When assembling, the male end connector 920 and the female end connector 930 are mated with each other to establish an electrical connection between the electromagnetic clutch and the circuit board 700, since the male end connector 920 and the female end connector 930 are matched in pairs design, the reliability of the connection between the two is basically not affected by the structure of the electromagnetic clutch and the circuit board 700 itself.

Embodiment 3

[0083] refer to Figure 7 , the difference between this embodiment and Embodiment 1 is that: the male connector 920 and the female connector 930 respectively have insertion holes and pins, that is, the male connector 920 is provided with pins 922, and the female connector 930 Insertion holes 932 are provided, such as split slot type insertion holes, wire spring insertion holes, crown spring insertion holes (insert holes with built-in multiple elastic reeds), etc., and the pins 922 are inserted into the insertion holes 932 . During assembly, the operator can observe the relative position of the insertion hole 932 and the pin 922 and align the two for insertion, which reduces the difficulty of assembly. After the assembly is completed, the pin 922 is not exposed, which has a good effect on the pin 922 Protect. As an equivalent variation of this embodiment, the male connector is provided with an insertion hole, the female connector is provided with a pin, and the pin is inserted...

Abstract

The invention discloses an electromechanical brake and an actuator thereof, and belongs to the mechanical braking technology field. The electromechanical brake and the actuator thereof solve the problems that a circuit board and an electromagnetic clutch of an existing actuator are high in electric connection cost and inconvenient to assemble. The actuator of the electromechanical brake comprisesa housing, a motor contained in the housing, an electromagnetic clutch contained in the housing, a circuit board contained in the housing and an electric connector, wherein the motor comprises a motorshaft, the electromagnetic clutch is used for locking or releasing the motor shaft, and the electric connector is used for building electric connection between the electromagnetic clutch and the circuit board. The actuator of the electromechanical brake does not need to use a tool or an auxiliary connection process in the assembling implementation process, shortens assembling time and reduces assembling cost. After installation of the electromagnetic clutch is completed, the electric connection between the circuit board and the electromagnetic clutch is synchronously built when the circuit board is installed, and vice versa, and therefore the rapid and reliable electric connection between the electromagnetic clutch and the circuit board is realized.

Description

【Technical field】 [0001] The invention relates to the technical field of mechanical braking, in particular to an actuator of an electromechanical brake and an electromechanical brake. 【Background technique】 [0002] An electromechanical brake (EMB) usually has an actuator and a disc brake. The torque generated by the actuator acts on the caliper of the disc brake through the mechanical structure to realize the compression of the caliper and the brake disc, thereby generating The required braking force, compared with the traditional electro-hydraulic brake (EHB), the electro-mechanical brake device is easier to manufacture and assemble, the brake response speed is fast, the control performance is good, and it is easy to realize the wire-controlled brake, replacing the electro-hydraulic brake. The braking device has advanced the traditional braking method a big step forward. [0003] An actuator, which is a power source of an electromechanical brake device, has a motor and an...
