Description

Technical Field

[0001] The present invention relates to a valve device for a new energy vehicle, and in particular to a five-way valve device for a new energy vehicle. Background Art

[0002] At present, new energy vehicles are developing rapidly. In the design of new energy vehicles, space layout is still a major problem, especially the cabin space. As vehicle functions become more and more complex, in order to better improve energy utilization, designers have to collect the available energy of the whole vehicle and develop a series of energy-saving solutions such as waste heat utilization and heat pump systems. This will also introduce more complex design circuits, more pipes and valves, and put more pressure on the already cramped cabin space. Therefore, the integrated design of parts is increasingly valued and is increasingly used. Although the existing three-way valves, four-way valves, and five-way valves on the market can also be applied to the pipeline system of new energy vehicles, for some specific pipeline systems, such as the pipeline system with circuit switching of 4 working modes, the existing three-way valves and four-way valves are required to cooperate for control. In this way, not only more valves need to be introduced, but also more pipes need to be introduced, which puts greater pressure on the already cramped cabin space. Summary of the invention

[0042] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments:

[0043] Specific embodiment 1: Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, a five-way valve device for new energy vehicles includes a valve housing, a valve core cavity arranged in the valve housing, a valve core 6 rotatably arranged in the valve core cavity, and a driving mechanism for driving the valve core to rotate. In this embodiment, the driving mechanism is a driving motor. The valve core cavity is a cylindrical cavity.

[0044] Two valve core channels 6.2 are provided in the valve core 6. A circulation groove 6.3 is provided on the side of the valve core. Both ends of the two valve core channels are connected to the same end face of the valve core and four valve core interfaces 6.1 are formed on the same end face of the valve core. In this embodiment, the four valve core interfaces are evenly distributed around the circumference of the rotation axis of the valve core, the outer side face of the valve core is a cylindrical surface, and the outer side face of the valve core is coaxially distributed with the rotation axis of the valve core. The valve core channel 6.2 is V-shaped or U-shaped. The circulation groove extends and distributes along the circumference of the rotation axis of the valve core. In this embodiment, a connecting port 6.4 connecting the circulation groove is also provided on the end face of the valve core where the valve core interface is located.

[0045] The valve housing is provided with a first channel 1, a second channel 2, a third channel 3, a fourth channel 4 and a fifth channel 5, wherein the first ends of the first channel, the second channel and the fourth channel are respectively connected to one end surface of the inner cavity of the valve core, and the first ends of the third channel and the fifth channel are respectively connected to the side wall of the inner cavity of the valve core. The first ends of the first channel, the second channel and the fourth channel are all facing the end surface of the valve core where the valve core interface is located. In this embodiment, the first end of the third channel and the first end of the fifth channel are symmetrically distributed on both sides of the rotation axis of the valve core. The second ends of the first channel, the second channel, the third channel, the fourth channel and the fifth channel are respectively connected to the outer surface of the valve housing.

[0046] The driving mechanism drives the valve core to rotate in the valve core inner cavity, so that one of the four valve core interfaces is sealedly connected to the first end of the first channel, another valve core interface is sealedly connected to the first end of the second channel, the third valve core interface is sealedly connected to the first end of the fourth channel, and the fourth valve core interface is connected to the third channel or the fifth channel through the valve core inner cavity and the circulation groove.

[0047] like Figure 6-Figure 9 As shown, the five-way valve device for new energy vehicles has four working modes, and the driving mechanism drives the valve core to rotate in the inner cavity of the valve core to achieve the switching of the four working modes, wherein:

[0048] In the first working mode, Figure 6 As shown, the outer side of the valve core seals the first end of the fifth channel (the first end of the fifth channel faces the outer side of the valve core), the first channel and the second channel are connected through a valve core channel, and the third channel is connected with the fourth channel through the flow groove, the valve core cavity and another valve core channel (the first end of the third channel faces the flow groove);

[0049] In the second working mode, if Figure 7 As shown, the outer side surface of the valve core seals the first end of the fifth channel (the first end of the fifth channel faces the outer side surface of the valve core), the second channel and the fourth channel are connected through a valve core channel, and the third channel is connected to the first channel through the flow groove, the valve core cavity and another valve core channel (the first end of the third channel faces the flow groove);

[0050] In the third working mode, if Figure 8 As shown, the outer side of the valve core seals the first end of the third channel (the first end of the third channel faces the outer side of the valve core), the fifth channel is connected to the fourth channel through the flow groove, the valve core cavity and a valve core channel, and the first channel and the second channel are connected through another valve core channel (the first end of the fifth channel faces the flow groove);

[0051] In the fourth working mode, if Fig. 9As shown, the outer side surface of the valve core seals the first end of the third channel (the first end of the third channel faces the outer side surface of the valve core), the fifth channel is connected to the first channel through the circulation groove, the valve core inner cavity and a valve core channel, and the second channel and the fourth channel are connected through another valve core channel (the first end of the fifth channel faces the circulation groove).

[0052] When the five-way valve device for new energy vehicles is in the first working mode, the driving mechanism drives the valve core to rotate 90 degrees in the inner cavity of the valve core, and the five-way valve device for new energy vehicles switches from the first working mode to the second working mode; then, the driving mechanism drives the valve core to continue to rotate 90 degrees in the same direction in the inner cavity of the valve core, and the five-way valve device for new energy vehicles switches from the second working mode to the third working mode; then, the driving mechanism drives the valve core to continue to rotate 90 degrees in the same direction in the inner cavity of the valve core, and the five-way valve device for new energy vehicles switches from the third working mode to the fourth working mode. In this way, the switching of the four working modes is realized by driving the valve core to rotate in the inner cavity of the valve core by the driving mechanism.

[0053] Compared with the prior art in which the circuit switching of the four working modes requires the use of the existing three-way valve and four-way valve in combination to achieve, which requires the introduction of more valves and pipes; the five-way valve device for new energy vehicles in this solution has four working positions, which can adapt to the needs of circuit switching of the four working modes. Only one five-way valve device is needed to achieve switching of the four working modes, which can reduce the number of required valves and pipes, thereby reducing the occupancy of the cabin space.

[0054] Specifically, Figure 1 , Figure 4 As shown, the valve housing includes a bottom shell 8 and a valve cover 7, and the valve cover and the bottom shell are connected by bolts. A valve core groove 8.1 is provided on the bottom shell, and the valve cover seals the notch of the valve core groove. The valve core groove constitutes the valve core inner cavity. The first ends of the first channel, the second channel and the fourth channel are connected to the bottom surface of the valve core groove, and the first ends of the first channel, the second channel and the fourth channel are distributed in sequence around the circumference of the rotation axis of the valve core. The valve core interface faces the bottom surface of the valve core groove. The driving mechanism is arranged on the outer side of the valve cover.

[0055] like Figure 4 As shown, in one implementation of this embodiment, the bottom shell is independently molded and manufactured, and the bottom shell is an integral structure, that is, the five-way valve device is an independent valve. The first channel, the second channel, the third channel, the fourth channel and the fifth channel are all arranged on the bottom shell. This is conducive to the manufacture of the five-way valve device and to improving the adaptability of the five-way valve device.

[0056] like Figure 5As shown, in another implementation of this embodiment, the bottom shell of the valve housing is formed by the kettle housing 9 of the new energy vehicle, that is, the bottom shell is integrated with the kettle housing of the new energy vehicle. The valve core groove is arranged on the outer surface of the kettle housing. In this way, the bottom shell is integrated with the kettle housing of the new energy vehicle, which can save a part and is conducive to further improving the compactness of the structure and reducing the occupation of the cabin space.

[0057] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any way. Any simple modification, change and equivalent transformation made to the above embodiment based on the technical essence of the present invention still falls within the protection scope of the technical solution of the present invention.
