Abstract
Description
Technical Field
[0001] The present application relates to the technical field of vehicle manufacturing, and in particular to an integrated multi-way valve and a vehicle. Background Art
[0002] The cooling water circuit control valves provided by the prior art automobiles are used in large numbers in the same system, are large in size, and occupy limited space in the entire vehicle. At the same time, with the increase of external connecting pipelines, the conversion ratio between energy and energy decreases, and the energy loss increases. In order to connect more pipelines, a large number of three-way valves, four-way valves, etc. are used, resulting in a large demand for vehicle control signals. Utility Model Content
[0003] The present application provides an integrated multi-way valve and a vehicle to solve the technical problem that the existing cooling water circuit needs to be provided with multiple three-way valves and four-way valves for separate control.
[0004] The first aspect of the utility model provides an integrated multi-way valve, comprising: a shell, a driving mechanism, a valve core and at least four interface pipes; the shell forms a first cavity, and a plurality of interface pipes are arranged on the shell and connected to the first cavity; the valve core is arranged in the first cavity and divides the first cavity into a plurality of second cavities, and each second cavity is connected to at least two interface pipes; the driving mechanism is arranged to drive the valve core to rotate so that each second cavity is connected to the interface pipe change.
[0005] In this solution, the shell forms a first cavity, and all fluids passing through the integrated multi-way valve provided by the utility model pass through the first cavity. Since multiple interface pipes are arranged on the shell and are connected to the first cavity, and since the valve core is arranged in the first cavity, and the valve core divides the first cavity into multiple second cavities, and the second cavities can be connected to at least two second interface pipes, when the driving mechanism drives the valve core to rotate, the interface pipe connected to each second cavity changes, that is, the purpose of switching the connection of different pipelines is achieved. Through the integrated multi-way valve, the use of structures such as three-way valves and four-way valves in management can be effectively reduced, and at the same time, it can be convenient for overall control.
[0006] In a further solution of the utility model, two ends of the valve core abut against the inner wall of the first cavity, and the valve core at least closes one interface pipe at any position during rotation.
[0007] In this solution, since both ends of the valve core are in contact with the inner wall of the first cavity, the valve core can close part of the interface pipe during control, thereby achieving the effect of disconnecting the pipeline, thereby efficiently controlling the entire pipeline system.
[0008] In a further solution of the utility model, at least four interface pipes are arranged in an annular shape on the circumferential surface of the shell, and adjacent interface pipes are arranged at equal angles in the circumferential direction of the shell.
[0009] In this solution, since at least four interface pipes are arranged in a ring shape on the circumferential surface of the shell, the entire integrated multi-way valve can be controlled by rotating the valve core, thereby controlling the connection relationship between the various interface pipes. The interface pipes arranged at equal angles can improve the accuracy of control when the valve core rotates.
[0010] In a further solution of the utility model, three pairs of interface pipes are provided, each pair of interface pipes are on the same axis, and the axis of the shell passes through the valve core; when the valve core stops rotating, any pair of interface pipes are closed at both ends, and the interface pipes not closed by the valve core are connected to the adjacent interface pipes.
[0011] In this scheme, three pairs of interface pipes are provided, and each pair of interface pipes are arranged opposite to each other on the shell and are not adjacent. Therefore, the interface pipes are arranged at intervals of 60° in the circumferential direction of the shell. Since the axis line of the shell passes through the valve core, the valve core will rotate around the axis line of the shell. When the valve core stops rotating (that is, when it is in a switching state), one pair of interface pipes will be closed, and the interface pipes not closed by the valve core will be connected to the adjacent interface pipes, thereby realizing the connection switching between the pipelines. At this time, the connected interface pipes must not be relative interface pipes.
[0012] In a further solution of the utility model, the valve core includes a connecting portion and a valve body portion, the connecting portion is connected to the driving mechanism; the end face of the valve body portion is an arc surface and the arc is the same as the arc of the inner wall of the shell, and the width of the end face of the valve body portion is greater than the diameter of the interface pipe.
[0013] In this solution, since the end face of the valve body is an arc surface and the curvature is the same as the curvature of the inner wall of the shell, it is convenient to seal a pair of interface parts when the valve core rotates. The connecting part should be parallel to the end face of the shell and abut against the inner wall of the first cavity, thereby effectively improving the sealing effect of the entire integrated multi-way valve. Since the width of the end face of the valve body is greater than the diameter of the interface pipe, the valve body can perfectly close the interface pipe to avoid incomplete closure of some interface pipes.
[0014] In a further embodiment of the present invention, the valve body comprises a first head portion and a second head portion connected to each other; an end of the first head portion away from the second head portion is an arc portion, and a radius of an end of the first head portion close to the second head portion is gradually reduced toward the second head portion; an end of the second head portion away from the first head portion is an arc portion, and a radius of an end of the second head portion close to the first head portion is gradually reduced toward the first head portion;
[0015] In this solution, by gradually reducing the radius of one end of the first head close to the second head and gradually reducing the radius of one end of the second head close to the first head toward the first head, the shape of the second cavity can be optimized to facilitate the flow of fluid in the second cavity.
[0016] In a further solution of the utility model, the driving mechanism includes a controller and a motor, the controller is electrically connected to the motor, so as to control the rotation of the valve core through the controller; the power output shaft of the motor coincides with the axis of the shell, and the valve core is connected to the power output shaft.
[0017] In a further solution of the utility model, the driving mechanism also includes a data interface, which is electrically connected to the controller and is used to transmit a control signal to the controller.
[0018] In this solution, the data interface is used to receive external signals. The controller controls the motor through the external signals transmitted by the data interface. The motor switches the pipeline connection by controlling the valve core, thereby reducing the use of four-way valves and three-way valves in the entire pipeline system.
[0019] In a further solution of the utility model, the connection point between the connection part and the driving mechanism is located on the axis center line of the housing, and the valve core rotates around the axis center line of the housing.
[0020] A vehicle of the utility model comprises the integrated multi-way valve provided in the first aspect of the utility model.
[0021] In summary, the integrated multi-way valve and vehicle provided by the present application have at least the following beneficial effects:
[0022] The shell forms a first cavity, and all fluids passing through the integrated multi-way valve provided by the utility model pass through the first cavity. Since multiple interface pipes are arranged on the shell and are connected to the first cavity, and since the valve core is arranged in the first cavity, and the valve core divides the first cavity into multiple second cavities, and the second cavities can be connected to at least two second interface pipes, when the driving mechanism drives the valve core to rotate, the interface pipe connected to each second cavity changes, that is, the purpose of switching the connection of different pipelines is achieved. Through the integrated multi-way valve, the use of structures such as three-way valves and four-way valves in management can be effectively reduced, and at the same time, it can be convenient for overall control.

[0041] Please refer to Figure 1-Figure 2 In a first aspect, the utility model provides an integrated multi-way valve, comprising: a shell 30, a driving mechanism 10, a valve core 20 and at least four interface pipes V; the shell 30 forms a first cavity 10A, and a plurality of interface pipes V are arranged on the shell 30 and communicated with the first cavity 10A; the valve core 20 is arranged in the first cavity 10A and divides the first cavity 10A into a plurality of second cavities 10A1, and each second cavity 10A1 is communicated with at least two interface pipes V; the driving mechanism 10 is arranged to drive the valve core 20 to rotate so that each second cavity 10A1 is connected to the interface pipe V to change.
[0042] In this solution, the shell 30 forms a first cavity 10A, and all fluids passing through the integrated multi-way valve provided by the utility model pass through the first cavity 10A. Since multiple interface pipes V are arranged on the shell 30 and are connected to the first cavity 10A, and the valve core 20 is arranged in the first cavity 10A, and the valve core 20 divides the first cavity 10A into multiple second cavities 10A1, and the second cavity 10A1 can be connected to at least two second interface pipes V, when the driving mechanism 10 drives the valve core 20 to rotate, the interface pipe V connected to each second cavity 10A1 changes, that is, the purpose of switching the connection of different pipelines is achieved. Through the integrated multi-way valve, the use of structures such as three-way valves and four-way valves in management can be effectively reduced, and at the same time, it can be convenient for overall control.
[0043] In a further solution of the present invention, both ends of the valve core 20 abut against the inner wall of the first cavity 10A, and the valve core 20 closes at least one interface tube V at any position during rotation.
[0044] In this solution, since both ends of the valve core 20 abut against the inner wall of the first cavity 10A, the valve core 20 can close part of the interface pipe V during control, thereby achieving the effect of pipeline disconnection, thereby efficiently controlling the entire pipeline system.
[0045] In a further solution of the present invention, at least four interface pipes V are arranged in an annular shape on the circumferential surface of the housing 30 , and adjacent interface pipes V are arranged at equal angles in the circumferential direction of the housing 30 .
[0046] In this solution, since at least four interface pipes V are arranged in a ring shape on the circumferential surface of the shell 30, the entire integrated multi-way valve can be controlled by rotating the valve core 20, thereby controlling the connection relationship between the various interface pipes V. The interface pipes V arranged at equal angles can improve the accuracy of control when the valve core 20 rotates.
[0047] In a further solution of the present invention, three pairs of interface tubes V are provided, each pair of interface tubes V is on the same axial line, and the axial line of the shell 30 passes through the valve core 20; when the valve core 20 stops rotating, any pair of interface tubes V are closed at both ends, and the interface tubes V not closed by the valve core 20 are connected to the adjacent interface tubes V.
[0048] In this solution, three pairs of interface tubes V are provided, and each pair of interface tubes V is arranged opposite to each other on the shell 30 and is not adjacent to each other. Therefore, the interface tubes V are arranged at intervals of 60° in the circumferential direction of the shell 30. Since the axis of the shell 30 passes through the valve core 20, the valve core 20 will rotate around the axis of the shell 30. When the valve core 20 stops rotating (that is, when it is in a switching state), one pair of interface tubes V will be closed, and the interface tubes V that are not closed by the valve core 20 will be connected to the adjacent interface tubes V, thereby realizing the connection switching between the pipelines. At this time, the connected interface tubes V must not be the relative interface tubes V.
[0049] In a further solution of the present invention, the valve core 20 includes a connecting portion 21 and a valve body portion 22, the connecting portion 21 is connected to the driving mechanism 10; the end face of the valve body portion 22 is an arc surface and the arc is the same as the arc of the inner wall of the shell 30, and the width of the end face of the valve body portion 22 is greater than the diameter of the interface pipe V.
[0050] In this solution, since the end face of the valve body 22 is an arc surface and the curvature is the same as the curvature of the inner wall of the shell 30, it is convenient for the valve core 20 to block a pair of interface parts when rotating. The connecting part 21 should be parallel to the end face of the shell 30 and abut against the inner wall of the first cavity 10A, thereby effectively improving the sealing effect of the entire integrated multi-way valve. Since the width of the end face of the valve body 22 is greater than the diameter of the interface pipe V, the valve body 22 can perfectly close the interface pipe V to avoid incomplete closing of part of the interface pipe V.
[0051] In a further embodiment of the present invention, the valve body 22 includes a first head and a second head connected to each other; one end of the first head away from the second head is an arc portion, and the radius of one end of the first head close to the second head is gradually reduced toward the second head; one end of the second head away from the first head is an arc portion, and the radius of one end of the second head close to the first head is gradually reduced toward the first head;
[0052] In this solution, by gradually reducing the radius of one end of the first head close to the second head and gradually reducing the radius of one end of the second head close to the first head, the shape of the second cavity 10A1 can be optimized to facilitate the flow of fluid in the second cavity 10A1.
[0053] In a further embodiment of the present invention, the driving mechanism 10 includes a controller 12 and a motor 13, and the controller 12 is electrically connected to the motor 13 to control the rotation of the valve core 20 through the controller 12; the power output shaft of the motor 13 coincides with the axis of the housing 30, and the valve core 20 is connected to the power output shaft.
[0054] In a further solution of the present utility model, the driving mechanism 10 further includes a data interface 11 , which is electrically connected to the controller 12 and is used to transmit a control signal to the controller 12 .
[0055] In this solution, the data interface 11 is used to receive external signals, and the controller 12 controls the motor 13 through the external signals transmitted by the data interface 11. The motor 13 realizes the switching of pipeline connectivity by controlling the valve core 20, thereby reducing the use of four-way valves and three-way valves in the entire pipeline system.
[0056] In a further solution of the present invention, the connection point between the connection part 21 and the driving mechanism 10 is located on the axis of the housing 30, and the valve core 20 rotates around the axis of the housing 30. The interface pipe V is also provided with an interface hole 30E when installed.

[0058] Specifically, the interface of the shell 30 includes a main body 31 and a bottom plate 32. The main body 31 and the bottom plate 32 are arranged to form a first cavity 10A.
