Description

Technical Field

[0002] The thermal management system of new energy vehicles includes a motor electric control thermal management system and a battery thermal management system. During the operation of the motor, a large amount of heat is generated, resulting in an increase in the motor temperature, a decrease in the output power of the motor, and a reduction in the vehicle power. Moreover, the battery pack also generates heat during use, and it is prone to explosion when the temperature of the battery pack is too high. Therefore, in the motor electric control thermal management system and the battery thermal management system, water cooling is usually used to cool them to achieve a rapid cooling effect. The electronic water valve is an important component for realizing the fluid management and distribution in the thermal management system.

[0047] This embodiment provides a non-central drive electronic water valve structure for solving the technical problem that the electronic water valve in the prior art cannot control multiple flow paths. The non-central drive electronic water valve structure includes a valve housing 1, a flow dividing block 2, a valve core 3 and a valve cover 4, wherein:

[0048] The valve housing 1 is a hollow cylinder structure, and an opening is provided at the bottom end of the valve housing 1.

[0049] The flow dividing block 2 is installed on the side wall of the valve housing 1. Six flow dividing ports are provided on the flow dividing block 2. The six flow dividing ports are all communicated with the valve housing 1. The six flow dividing ports are respectively port A, port B, port D, port E, port G1 and port G2. Specifically, six through holes are provided on the side wall of the valve housing 1. The six through holes are respectively arranged in one-to-one correspondence with the six flow dividing ports. And port A, port E and port B are respectively located above port G2, port D and port G1. Optionally, the flow dividing block 2 and the valve housing 1 can be installed together by bonding or hot melting. Of course, they can also be integrally formed.

[0050] One end of the valve core 3 is rotatably installed on the inner top wall of the valve housing 1. Two longitudinal communication ports and two transverse communication ports are provided on the outer side wall of the valve core 3.

The two transverse communication ports are arranged along the axial direction of the valve core 3. And the two longitudinal communication ports and the two transverse communication ports are symmetrically arranged along the axis of the valve core 3. The two longitudinal communication ports are respectively port a and port b. The two transverse communication ports are respectively port c and port d. Through the arrangement of the transverse communication ports and the longitudinal communication ports on the valve core 3, by rotating the valve core 3, adjacent two flow dividing ports on the same horizontal plane or adjacent two flow dividing ports on the same vertical plane can be selected to be communicated. In this way, the function of controlling multiple flow paths simultaneously is achieved.

[0051] With the above structure, when using the non-centered driving electronic water valve structure provided by the present utility model, when the valve core 3 is in the initial state, that is, state one, port A is connected to port G2 and port D is connected to port E through port a and port b respectively; when the valve core 3 is driven to rotate counterclockwise by 60°, that is, when the valve core 3 is in state two, port D is connected to port E and port B is connected to port G1 through port a and port b respectively; when the valve core 3 is driven to rotate counterclockwise by 180°, that is, when the valve core 3 is in state three, port G2 is connected to port D and port A is connected to port E through port c and port d respectively; when the valve core 3 is driven to rotate counterclockwise by 240°, that is, when the valve core 3 is in state four, port G1 is connected to port D and port B is connected to port E through port c and port d respectively. In this way, through the cooperation of the valve core 3 and the flow dividing block 2, by driving the valve core 3 to rotate different angles, the six flow dividing ports on the valve core 3 are in different communication states, that is, by rotating the valve core 3 to control multiple flow paths to adapt to different usage scenarios, which not only saves installation space but also saves costs, and has stronger practicability.

[0061] With the above structure, the driving motor 5 is connected to the power supply, so that the rotating shaft on the driving motor 5 rotates, thereby driving the first driving wheel 6 connected to the rotating shaft of the driving motor 5 to rotate synchronously. The first driving wheel 6 meshes with the first driven wheel 8, further driving the first driven wheel 8 to rotate, and then driving the transmission shaft 7 connected to the first driven wheel 8 to rotate on the valve housing 1.
