Detailed Implementation

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0028] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0029] like Figures 1-9 As shown in the figure, this utility model provides a multi-way valve for a thermal management system of a new energy vehicle, including a multi-way valve body 1, and a plurality of connecting rods 4 connected to the surface of the multi-way valve body 1. One end of the plurality of connecting rods 4 is connected to a mounting housing 2, and an upper end cover 3 is connected to the surface of the mounting housing 2. An electronic connector 21 is installed on the outside of the mounting housing 2.

[0030] A sealing sheet 6 is provided between the valve body 1 of the multi-way valve and the mounting housing 2. Valve chambers 10 are symmetrically opened on both sides of the surface of the valve body 1 of the multi-way valve. Several first side channels 11 are opened at equal intervals inside the valve chambers 10. The interiors of the two valve chambers 10 are connected by a connecting channel 8. Several end face channels 13 are opened on the surface of the valve body 1 away from the mounting housing 2, and the end face channels 13 are connected to the first side channels 11.

[0031] A sealing ring 9 is connected inside the valve chamber 10, and the surface of the sealing ring 9 has several second side channels 12. A valve core 7 is connected inside the sealing ring 9, and the surface of the valve core 7 has several grooves. The inner diameter of the valve chamber 10 is the same as the outer diameter of the sealing ring 9, and the inner diameter of the sealing ring 9 is the same as the outer diameter of the valve core 7. The sealing rings 9 inside the two valve chambers 10 have connecting openings at their close positions, and the positions of the connecting openings correspond to the positions of the connecting channels 8.

[0032] The number of first side channels 11 in each valve chamber 10 is 5. The number of end face channels 13 and second side channels 12 is the same as that of the first side channels 11. The shape of the second side channel 12 is adapted to the shape of the first side channel 11, and the position of the second side channel 12 corresponds to the position of the first side channel 11.

[0033] The housing 2 is equipped with two sets of drive components. One end of the valve core 7 is provided with a rotating block 5, and the drive components are used to drive the rotating block 5 to rotate.

[0034] In one embodiment of the utility model, through the two valve cavities 10 on the multi-way valve body 1 are communicated together in the mode of connecting channel 8, one valve cavity 10 can be used as liquid inlet area, and the other valve cavity 10 can be used as liquid outlet area, so as to realize the valve body function.

[0035] In the technical scheme, ten first side channels 11 are arranged in the two valve cavities 10, so that the multi-way valve works as a ten-way valve.

[0036] The specific working mode of the ten-way valve is as follows: when the valve body needs to be in the open state, the rotating block 5 is driven to rotate by the driving assembly, so that the valve core 7 rotates in the interior of the sealing ring 9; because the outer surface of the valve core 7 is in a sealed and tightly connected state with the inner wall of the sealing ring 9, liquid cannot enter the gap between the valve core 7 and the sealing ring 9.

[0037] When the valve core 7 rotates to a certain position, i.e., the valve core 7 on the valve core 7 corresponds to the second side channel 12, i.e., the second side channel 12 is only in a communication state with the valve core 7, liquid cannot flow in the valve body, because the liquid entering the second side channel 12 is completely blocked by the valve core 7; when the valve body needs to be opened, the valve core 7 is rotated to the region not corresponding to the second side channel 12. The liquid entering the interior of the valve body flows between the two valve cavities 10 through the connecting channel 8.

[0038] In the embodiment, the driving assembly includes a driving motor 15, and the driving motor 15 is installed in the interior of the mounting shell 2; the output end of the driving motor 15 is provided with a transmission worm 16; the interior of the mounting shell 2 is rotatably provided with a transmission worm wheel 17, and the surface of the transmission worm wheel 17 is provided with a first transmission gear 18. The interior of the mounting shell 2 is rotatably provided with a double gear set 19, and the interior of the upper end cover 3 is connected with a mounting panel 14; the surface of the mounting panel 14 is rotatably provided with a second transmission gear 20, and the second transmission gear 20 is connected with the rotating block 5.

[0039] The double gear set 19 and the transmission worm wheel 17 are rotatably installed in the interior of the mounting shell 2 through a transmission shaft, and the second transmission gear 20 is rotatably installed on the mounting panel 14 through a rotating shaft.

[0040] The transmission worm 16 is in meshing connection with the transmission worm wheel 17, the first transmission gear 18 is in meshing connection with a group of gears of the double gear set 19, and another group of gears of the double gear set 19 is in meshing connection with the second transmission gear 20.

[0041] In this embodiment, the working process of the drive assembly starts from the drive motor 15. The drive motor 15 is connected to the transmission worm 16 through the output end, and the transmission worm 16 is engaged with the transmission worm gear 17 installed in the mounting shell 2. After the drive motor 15 is started, the transmission worm 16 drives the worm gear 17 to rotate, thereby providing power for the entire transmission system.

[0042] The transmission worm gear 17 drives the first transmission gear 18 to rotate through its rotation. The first transmission gear 18 is engaged with a set of gears in the double gear set 19, thereby driving the double gear set 19 to rotate. The other set of gears in the double gear set 19 drives the second transmission gear 20 to rotate.

[0043] The second transmission gear 20 is installed on the mounting panel 14 through the rotating shaft and is connected to the rotating block 5. When the second transmission gear 20 rotates, it drives the rotating block 5 to rotate correspondingly. In this way, the entire transmission system realizes power transmission from the drive motor 15 to the rotating block 5, ensuring the normal operation of the multi-way valve.

[0044] In this embodiment, sealing rings are provided at the connection between the rotating block 5 and the sealing piece 6, and between the second transmission gear 20 and the mounting shell 2.

[0045] It can effectively prevent the leakage of liquid or gas. The sealing ring plays an important sealing role, ensuring that the fluid inside the system does not leak at the key parts, thereby improving the sealing performance of the valve body and the stability of the overall operation.

[0046] In addition, the sealing ring can reduce the pressure fluctuations caused by the leakage of liquid or gas, avoiding negative effects on the performance of the system. It can also effectively isolate the external environment from the internal transmission components, preventing external pollutants from entering the valve body, protecting the long-term stable operation of the rotating block, transmission gear and other key components, and prolonging the service life of the equipment. Therefore, the design of the sealing ring not only improves the sealing performance, but also improves the reliability and durability of the equipment.

[0047] The above only describes the preferred embodiments of the present application and is not intended to limit the present application. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present application shall be included in the protection scope of the present application.
