[0042] The dynamic sealing structure of the utility model is a new type of impurity-proof dynamic sealing structure used in a thermal management module based on an electronically controlled actuator. Figures 1 to 3 As shown, the utility model provides a dynamic sealing structure, which includes a housing 1, a dynamic sealing module 2, a first sealing ring 3, a second sealing ring 4 and a ball valve 5. The housing 1 is formed with a channel having an opening, and a clamping groove 14 is circumferentially arranged on the inner wall of the channel, and the clamping groove 14 is close to the opening. The dynamic sealing module 2 and the first sealing ring 3 are sequentially sealed and connected to the inner wall of the channel, one side of the second sealing ring 4 is sealed and connected to the dynamic sealing module 2, and the other side extends from the inside of the channel to the outside to the opening, the first sealing ring 3 is sealingly clamped in the clamping groove 14, and the first sealing ring 3 is sealed and connected to the outer ring of the second sealing ring 4, and the ball valve 5 is located at the opening and is in sealing contact with the second sealing ring 4. The utility model adds a first sealing ring 3 at the opening of the shell 1, and installs a second sealing ring 4 and a dynamic sealing module 2 in the shell 1, forms a seal between the dynamic sealing module and the shell, and forms a seal between the first sealing ring and the shell, so that the two sealing structures work together, thereby overcoming the defects of the prior art that pollutants such as mud and sand impurities, aluminum filings, iron filings, etc. in the cooling water enter the dynamic sealing structure, causing the dynamic sealing structure to become stuck and fail, and the shell and the ball valve sealing ring to wear.

[0043] As a preferred embodiment, the first sealing ring 3 is a rubber ring, including but not limited to an O-ring, an X-ring or other special-shaped sealing rings.

[0044] As a preferred embodiment, the first sealing ring 3 is clamped in the slot 14, and the first sealing ring 3 has a first sealing ring outer ring 31 and a first sealing ring inner ring 32. The first sealing ring outer ring 31 is in interference connection with the bottom wall of the slot, thereby limiting the radial movement of the first sealing ring and playing a sealing role. The side wall of the slot limits the axial movement of the first sealing ring 3, and the radial and axial limitation of the first sealing ring by the slot ensures the sealing effect between the first sealing ring 3 and the shell, which can prevent the jamming and wear caused by the entry of impurities. The first sealing ring inner ring 32 is in interference connection with the outer ring of the second sealing ring 4. When the second sealing ring 4 moves up and down, the first sealing ring 3 is always in contact with it, which can prevent the impurity particles in the coolant from entering the inner wall area of ​​the shell, causing the thermal management module to jam and the wear of related parts. At the same time, the second sealing ring 4 is in sealing contact with the ball valve 5 to control the leakage.

[0045] Please continue reading Figures 1 to 3 In a preferred embodiment, the channel 10 includes a first channel 11, a second channel 12 and a third channel 13 which are connected in sequence. The inner diameter of the third channel 13 is larger than the inner diameter of the first channel 11. The second channel 12 is a tapered channel, and the inner diameter of the second channel 12 decreases from the third channel 13 to the first channel 11. The dynamic sealing module 2 is located in the first channel 11 and is interference-connected with the inner wall of the first channel 11. The second sealing ring 4 passes through the second channel 12 and the third channel 13 in sequence from the first channel 11 to the opening, and the second sealing ring 4 is sealed and connected to the dynamic sealing module 2 and the first sealing ring 3 respectively. The slot 14 is opened on the inner wall of the third channel 13, and the axial length of the third channel 13 is larger than the width of the slot 14.

[0046] Please continue reading Figures 1 to 4 In a preferred embodiment, the dynamic sealing module 2 is a cylindrical structure. The dynamic sealing module is a module that can still play a sealing role in a dynamic working state. The outer ring of the dynamic sealing module 2 has a protruding structure 21, and the protruding structure 21 has a mounting bevel 211. The inclination direction of the mounting bevel 211 is consistent with the inclination direction of the conical surface of the second channel 12, and the protruding structure 21 is connected with the inner wall of the first channel 11 by interference fit, thereby preventing the dynamic sealing module 2 from radially moving and playing a sealing role at the same time. The utility model limits the dynamic sealing module 2 in the radial direction by interference fit between the dynamic sealing module 2 and the inner wall of the first channel 11, thereby ensuring the radial sealing effect of the dynamic sealing module. The conical surface of the second channel 12 is to prevent the sealing ring of the dynamic sealing module 2 from flipping during assembly. At the same time, when the second sealing ring 4 is squeezed and moves upward, the conical surface of the second channel 12 can better contact with the second sealing ring 4, thereby reducing the accumulation of impurities between the housing and the second sealing ring.

[0047] Please continue reading Figures 1 to 6 The second sealing ring 4 is a ball valve sealing ring. The outer ring of the second sealing ring 4 has an outer ring upper plane 40, an outer ring lower plane 41 and an outer ring inclined surface 45 located between the outer ring upper plane 40 and the outer ring lower plane 41. The inclined direction of the outer ring inclined surface 45 is consistent with the inclined direction of the tapered channel. The inner ring of the second sealing ring 4 has an inclined surface 42, and the inclined surface 42 is located at the opening. The outer ring upper plane 40 can move along the inner wall of the first channel 11, the outer ring lower plane 41 can move along the inner wall of the third channel 13, and the outer ring inclined surface 45 can move along the second channel. When the second sealing ring 4 is squeezed, the outer ring inclined surface 45 cooperates with the tapered surface of the second channel so that the outer ring of the second sealing ring can better contact the inner wall of the housing, thereby reducing or eliminating the gap between the second sealing ring and the housing. The inner ring 32 of the first sealing ring is connected to the lower plane 41 of the outer ring by interference, so as to limit the movement in the radial direction, play a sealing role and prevent the jamming and wear caused by the entry of impurities. At the same time, the inner ring 32 of the first sealing ring is connected to the lower plane 41 of the outer ring by interference, so that the axial matching length between the outer ring of the second sealing ring 4 and the housing is shortened, thereby reducing the accumulation of impurities in the cooling water between the housing and the second sealing ring 4, resulting in jamming and wear. When the dynamic sealing structure is in a closed state, the ball valve 5 seals against the inclined surface 42 of the second sealing ring 4. The ball valve 5 seals against the inclined surface 42, and the ball valve plays a sealing role during the rotation process, and the liquid does not leak at this seal.

[0048] In another embodiment, the dynamic sealing module 2 includes a cylindrical sealing ring 20 and a reinforced sealing ring 22, wherein the reinforced sealing ring 22 is arranged on the outer ring of the cylindrical sealing ring 20, the reinforced sealing ring 22 is close to the outer ring center of the cylindrical sealing ring 20, and the protrusion structure 21 is arranged on the reinforced sealing ring 22. The inner ring of the second sealing ring 4 also has an inner ring upper plane 43 and an inner ring lower plane 44. Along the axial direction of the channel, the inner ring upper plane 43 of the second sealing ring seals against the outer ring of the cylindrical sealing ring 20, and the inner ring of the cylindrical sealing ring 20 is flush with the inner ring lower plane 44 of the second sealing ring 4, thereby improving the sealing performance.

[0049] See also Figure 7 Preferably, the ball valve 5 is a plastic ball valve having a spherical structure 51, and the spherical structure 51 is in sealing contact with the inclined surface 42. The ball valve 5 is a double ball valve or a single ball valve. During the rotation of the ball valve, the spherical structure 51 of the ball valve cooperates with the inclined surface of the ball valve sealing ring to perform a sealing function.

[0050] Please continue reading Figures 1 to 3 ,like Figure 1As shown, when the ball valve 5 rotates to the flow port (not shown) on the ball valve to dock with the channel 10 of the shell 1, the dynamic sealing structure is in an open state. At this time, the ball valve 5 pushes the second sealing ring 4 into the channel 10 of the shell 1. The second sealing ring 4 and the dynamic sealing module 2 are deformed due to force compression. The upper plane 40 of the outer ring of the second sealing ring 4 moves upward close to the axial inner wall 111 of the first channel, and the dynamic sealing module 2 contacts the radial inner wall 112 of the first channel, so that the gap between the dynamic sealing module 2 and the shell 1 and the gap between the second sealing ring 4 and the inner wall of the shell 1 are reduced or disappear, thereby preventing impurities in the fluid in the channel from accumulating between the dynamic sealing module 2 and the shell and between the second sealing ring and the shell. At the same time, through the interference connection between the dynamic sealing module 2 and the shell 1, the interference connection between the first sealing ring 3 and the shell 1, and the interference connection between the first sealing ring 3 and the second sealing ring 4, it can effectively prevent pollutants such as silt, aluminum filings, and iron filings in the cooling water flowing through the channel and the flow port of the ball valve from entering the dynamic sealing structure, thereby causing defects such as the dynamic sealing structure being stuck and failing and impurities entering the dynamic sealing structure causing parts wear.

[0051] like Figure 2 As shown, when the ball valve 5 rotates to close the channel 10 of the shell 1, the dynamic sealing structure is in a closed state, and the elastic force of the dynamic sealing module 2 and the second sealing ring 4 is restored. At this time, there will be a certain gap between the second sealing ring 4 and the inner wall of the shell 1, but because the dynamic sealing module 2 is in interference connection with the inner wall of the shell 1, the first sealing ring 3 and the second sealing ring 4 are in interference connection, and the first sealing ring 3 is in interference connection with the shell 1, it can still effectively prevent pollutants such as mud, aluminum filings, and iron filings in the cooling water in the channel from entering the dynamic sealing structure.

[0052] The utility model also provides a thermal management module, which comprises an electronically controlled actuator, and the thermal management module comprises the above-mentioned dynamic sealing structure.

[0053] The utility model is to overcome the shortcomings of the prior art, add a first sealing ring structure at the shell opening, install the first sealing ring, the second sealing ring, the dynamic sealing module, etc. into the shell, and the first sealing ring and the dynamic sealing module seal structure work together to overcome the defects of the prior art that the sand impurities, aluminum filings, iron filings and other pollutants in the cooling water enter the dynamic sealing structure, resulting in the dynamic sealing structure being stuck and failing and the shell and the ball valve sealing ring being worn. A radial interference fit is adopted between the first sealing ring and the shell, between the first sealing ring and the second sealing ring, and between the dynamic sealing module and the shell, and the interference fit can effectively prevent the sand impurities and other pollutants in the cooling water from entering the inner wall area of ​​the shell, resulting in the failure of the dynamic sealing structure function.
