A driving structure using a motor as a power source is generally called an electric drive. The motor is integrated into the housing of the electric drive to form an electric drive assembly. The motor comprises a stator and a rotor, and the rotor is driven to rotate through the stator so as to convert electric energy into mechanical energy, and accordingly torque is output outwards.

Because the stator drives the rotor to rotate, the motor always generates heat, and cooling liquid such as lubricating oil is required to be supplied to the motor so as to cool the motor and ensure the stable operation of the motor. And after the motor temperature drops, it is necessary to stop or reduce the supply of the cooling liquid. In addition, other devices of the electric drive assembly often need to be subjected to temperature control so as to be in a set working temperature range, and the stable operation of each component is ensured. This requires the use of a thermostatic valve to control the flow of coolant, to control the flow of coolant to a given cooling circuit, and to bypass the given cooling circuit. Most of the current temperature control valves are of rotary structures, that is, a rotary power source such as a motor drives a valve core to perform rotary motion so as to control and regulate the flow direction of cooling liquid. However, the electric drive assembly mostly uses a linear reciprocating drive structure, which makes the current rotary temperature control valve difficult to adapt, that is, the rotary temperature control valve cannot adapt to the linear reciprocating adjustment scene.

Based on the above consideration, in order to solve the problem that the temperature control valve cannot adapt to the situation of linear reciprocating motion adjustment, the embodiment of the application provides an electrically driven control valve, wherein a sliding hole is formed in a valve body, a first flow channel, a second flow channel and a third flow channel which are communicated with the sliding hole are formed in the valve body, a valve core is arranged in the sliding hole in a sliding mode, a linear driver is arranged to push the valve core to linearly move in the sliding hole of the valve body, so that the opening between the first flow channel and the second flow channel and the opening between the first flow channel and the third flow channel are adjusted, and the flow of liquid in the first flow channel to the second flow channel and the third flow channel is adjusted through linear reciprocation of the valve core, so that the electrically driven control valve adapts to the situation of linear reciprocating motion adjustment.

Among other things, spacecraft may include airplanes, rockets, space shuttles, spacecraft, and the like.

The electric drive assembly disclosed by the embodiment of the application can be applied to a vehicle to be used as a power source of the vehicle.

An electrically driven control valve 100 includes a valve body 10, a valve spool 20, and a linear actuator 30. Wherein: the valve body 10 is a main body case structure of the electrically driven control valve 100. The valve element 20 is provided in the valve body 10 to control the degree of opening (i.e., the opening degree) of the flow passage in the valve body 10. The linear actuator 30 refers to a power device that can drive an object to move in a straight line, such as can drive the valve element 20 to reciprocate in a straight line in the valve body 10.

The valve body 10 is provided with a slide hole 11, and the slide hole 11 is a hole structure arranged on the valve body 10. The valve body 10 is further provided with a flow passage, which is a channel structure provided in the valve body 10 and through which liquid can flow, and may be a hole structure provided in the valve body 10, a pipe structure provided in the valve body 10, or the like, so that liquid can flow through the flow passage. The flow passages on the valve body 10 include a first flow passage 121, a second flow passage 122 and a third flow passage 123, that is, the valve body 10 is provided with the first flow passage 121, the second flow passage 122 and the third flow passage 123. The first flow passage 121, the second flow passage 122 and the third flow passage 123 are respectively communicated with the slide hole 11, that is, one end of the first flow passage 121 extends to the slide hole 11 to be connected with the slide hole 11; one end of the second flow channel 122 extends to the sliding hole 11 to be connected with the sliding hole 11; one end of the third flow channel 123 extends to the sliding hole 11 to be connected with the sliding hole 11; thus, the liquid can enter from the first flow passage 121, enter the second flow passage 122 and the third flow passage 123 through the slide hole 11, and flow out, but can also enter from the second flow passage 122 and the third flow passage 123, enter the first flow passage 121 through the slide hole 11, and flow out.

The valve core 20 is a part movably installed in the valve body 10, and the valve body 10 performs a basic function of direction control, pressure control, or flow control by its movement. The valve body 10 is combined with the valve core 20 to form a valve. The valve core 20 is slidably disposed in the slide hole 11 and is movable in the valve body 10 in the axial direction of the slide hole 11, so that the valve core 20 can be linearly moved back and forth in the axial direction of the slide hole 11.

A linear actuator 30 is connected to the spool 20 to actuate the spool 20 to move in the spool 11 in the axial direction of the spool 11. The valve core 20 moves in the sliding hole 11 to adjust the opening between the first flow passage 121 and the second flow passage 122 and the opening between the first flow passage 121 and the third flow passage 123, so as to control the flow direction of the liquid in the valve body 10 and the flow rate in each flow direction, so as to adapt to the straight reciprocating motion type adjustment scene, especially when being applied to temperature control, the flow rate of each flow direction is controllable, and the temperature control corresponding to the flow direction is realized. If the first flow passage 121 is used as a liquid inlet, the second flow passage 122 and the third flow passage 123 are used as liquid outlets, the amount of liquid entering the second flow passage 122 and the third flow passage 123 of the first flow passage 121 can be controlled to be used for temperature control, and when the first flow passage 121 is supplied with cooling liquid, the amount of cooling liquid entering the two cooling circuits with the second flow passage 122 and the third flow passage 123 can be controlled to realize temperature control for the two cooling circuits.

Of course, in use, the first flow path 121 serves as a liquid outlet, the second flow path 122 and the third flow path 123 serve as liquid inlets, so that the amount of liquid entering the first flow path 121 in the second flow path 122 and the third flow path 123 can be controlled, particularly for temperature control, and in supplying the cooling liquid to the second flow path 122, the third flow path 123 supplies the high-temperature liquid, and the temperature of the mixed liquid in the first flow path 121 is controlled by controlling the amount of liquid entering the first flow path 121 in the second flow path 122 and the third flow path 123, thereby controlling the temperature of the liquid flowing out of the first flow path 121.

The opening degree refers to the opening degree of the valve, and the ratio of the flow rate of a certain position of the valve to the maximum flow rate of the valve is 100% when the flow rate of the valve is maximum; when the valve is closed, the opening degree is 0. The opening between the first and second flow paths 121 and 122 refers to the ratio of the actual flow rate to the maximum flow rate between the first and second flow paths 121 and 122. The opening degree between the first flow path 121 and the third flow path 123 means a ratio of an actual flow rate to a maximum flow rate between the first flow path 121 and the third flow path 123.

In the technical scheme of the embodiment of the application, the valve core 20 is driven to move along the sliding hole 11 by arranging the linear driver 30 so as to adjust the opening between the first flow channel 121 and the second flow channel 122 and the opening between the first flow channel 121 and the third flow channel 123, so that the flow rate of the first flow channel 121 to the liquid in the second flow channel 122 and the third flow channel 123 is adjusted by the linear reciprocation of the valve core 20, and the linear reciprocation type adjusting scene is adapted.

In some embodiments, the linear actuator 30 includes a linear motor 31, and the linear motor 31 is coupled to the valve spool 20. The linear motor 31 is used for driving the valve core 20 to move in the slide hole 11, so that the structure is simple, the assembly is convenient, and the control is also convenient.

In some embodiments, the linear drive 30 may also use linear modules such as a lead screw nut mechanism, a rack and pinion mechanism, and the like.

Since the first flow passage 121, the second flow passage 122, and the third flow passage 123 communicate with the slide hole 11, respectively, a mouth portion may be formed at the communication position of the first flow passage 121 and the slide hole 11, the mouth portion being defined as a first communication port 131, that is, the first flow passage 121 and the slide hole 11 have the first communication port 131; a mouth portion may be formed at a communication portion of the second flow passage 122 with the slide hole 11, the mouth portion being defined as a second communication port, that is, the second flow passage 122 and the slide hole 11 have a second communication port 132; a mouth portion may be formed at a communication portion of the third flow passage 123 with the slide hole 11, and the mouth portion is defined as a third communication port 133, that is, the third flow passage 123 and the slide hole 11 have a first communication port 131.

In some embodiments, the valve core 20 is provided with a communication flow passage 21. The communication flow passage 21 is a passage structure provided in the valve body 20 and through which a liquid can flow. The communication flow passage 21 is used to communicate the first flow passage 121 with the second flow passage 122, that is, when the spool 20 moves in the spool 11, the first flow passage 121 can be made to communicate with the second flow passage 122 via the communication flow passage 21. The valve core 20 is provided with a plug 22, the plug 22 refers to a plugging structure arranged on the valve core 20, for example, the plug 22 can be a block, a step and other structures arranged on the valve core 20, and the shape of the plug 22 is matched with the shape of the sliding hole 11. The plug 22 is used to block the communication between the first flow passage 121 and the second flow passage 122 or to block the communication between the first flow passage 121 and the third flow passage 123. Since the first flow channel 121 and the second flow channel 122 are both communicated with the slide hole 11, a part of the slide hole 11 between the first flow channel 121 and the second flow channel 122 is communicated with the first flow channel 121 and the second flow channel 122, and the plug 22 seals off the part, so that the communication part between the first flow channel 121 and the second flow channel 122 is sealed off, and the first flow channel 121 and the second flow channel 122 are disconnected. Similarly, since the first flow channel 121 and the third flow channel 123 are both in communication with the slide hole 11, a portion of the slide hole 11 between the first flow channel 121 and the third flow channel 123 is in communication with the first flow channel 121 and the third flow channel 123, and the plug 22 closes the portion to block the communication between the first flow channel 121 and the third flow channel 123, so as to disconnect the first flow channel 121 from the third flow channel 123. The plug 22 is provided on one side of the communication flow passage 21 close to the third flow passage 123.
