[0032] According to a sealing member disclosed in the present invention, a sealing member is used for sealing between housings and functional members 11 extending from the housings, such as Figures 1 to 6As shown, it includes a first sealing member 12 and a second sealing member 13 extending from the first sealing member 12, the second sealing member 13 and part of the first sealing member 12 form an annular structure 14, the first sealing member 12 is arranged between the shells to form a first sealing structure, and the annular structure 14 is sleeved on the functional part 11 and forms a second sealing structure with the shell.

[0033] By integrating the first sealing component 12 and the second sealing component 13 into one, the assembly process between the shell and the functional part 11 can be simplified. At the same time, the sealing effect between the shells and between the shell and the functional part 11 can be enhanced, eliminating the process of setting sealant, improving production efficiency, and facilitating later product maintenance.

[0034] The second sealing member 13 may be an arc-shaped structure; the arc-shaped structure has at least one bending portion, and the bending portion can adapt to the sharp corner structures on both sides of the functional part 11 to increase the wear resistance and pressure resistance of the seal.

[0035] According to an embodiment of a seal disclosed herein, the first sealing member 12 is a closed structure connected end to end, and both ends of the second sealing member 13 are respectively connected to one side of the first sealing member 12 .

[0036] The first sealing member 12 is a closed structure closed in the circumferential direction. The two ends of the second sealing member 13 are connected to one side of the first sealing member 12 to form an annular structure 14 for being sleeved on the outer periphery of the functional part 11, thereby achieving sealing between the shells and between the shell and the functional part 11 through a sealing member.

[0037] Specifically, the plane where the second sealing member 13 is located forms a set angle with the plane where at least the portion of the first sealing member 12 connected to the second sealing member 13 is located, so as to adapt to the functional component 11 protruding from the housing at any angle.

[0038] According to a control box disclosed herein, the control box includes an upper shell 15, a lower shell 16, and a functional part 11 extending from between the upper shell 15 and the lower shell 16, as well as a seal of any of the above embodiments. A groove 17 is provided at the joint between the upper shell 15 and the lower shell 16. The groove 17 between the upper shell 15 and the lower shell 16 relatively forms a first sealing groove. A second sealing groove is formed between the groove 17 of part of the upper shell 15 and the functional part 11. The first sealing member 12 is located in the first sealing groove, and the second sealing member 13 is located in the second sealing groove.

[0039] By means of the groove 17 provided between the upper shell 15 and the lower shell 16, the seal can be clamped between the upper shell 15 and the lower shell 16, thereby achieving sealing at the docking position of the upper shell 15 and the lower shell 16; the second sealing groove can clamp the second sealing component 13 between the functional part 11 and the upper shell 15, thereby achieving sealing between the upper shell 15 and the lower shell 16 and the functional part 11. By providing the groove 17, the seal can be prevented from shifting, thereby affecting the sealing effect.

[0040] In a specific implementation, the control box 10 may be a charging communication protocol controller; the functional component 11 may be a connector.

[0041] Specifically, the first sealing member 12 and the second sealing member 13 are provided with at least one first peak portion 18 protruding from the surface corresponding to the bottom of the groove 17 and extending along the extending direction of the first sealing member 12 and the second sealing member 13 .

[0042] By providing the first peak portion 18 , an interference fit can be provided during the connection process between the upper shell 15 and the lower shell 16 to enhance the sealing effect between the upper shell 15 and the lower shell 16 .

[0043] More specifically, the first peak 18 on the outer circumferential surface of the annular structure 14 of the second sealing member 13 and the first peak 18 on the surface of the first sealing member 12 extending to the second sealing member 13 are connected end to end at the connection between the first sealing member 12 and the second sealing member 13. The first peak 18 is provided on both sides of the surface where the seal contacts the upper shell 15 and the lower shell 16, so that the seal forms an interference fit in the circumferential direction of the upper shell 15 and the lower shell 16.

[0044] More specifically, at least one second peak 19 is protruded from the inner surface of the annular structure 14 and extends along the extension direction of the annular structure 14. When the functional component 11 is assembled in the housing, the second peak 19 provides interference and strengthens the sealing effect between the functional component 11 and the upper housing 15 and the lower housing 16.

[0045] More specifically, the annular structure 14 is provided with a circumferentially extending additional portion 20 protruding along the extending direction of the functional component 11. The additional portion 20 is sleeved onto the functional component 11. The additional portion 20 is clamped between the upper shell 15 and the lower shell 16 to hold the functional component 11. A portion of the additional portion 20 is exposed to the outside, thereby forming an auxiliary sealing function between the functional component 11 and the shell, thereby enhancing the sealing effect.

[0046] More specifically, if Figure 2 As shown, the cross section of the additional portion 20 is wedge-shaped, and the size of the additional portion 20 gradually decreases from the side close to the annular structure 14 toward the free end of the functional part 11.

[0047] The thickness of the additional portion 20 along the radial direction of the functional part 11 gradually decreases from the side close to the annular structure 14 toward the free end of the functional part 11, so as to facilitate the upper shell 15 and the lower shell 16 to clamp the additional portion 20 and fasten it to the outer periphery of the functional part 11.

[0048] When implementing it specifically, Figure 3 As shown, the cross-section of the additional part 20 can also be rectangular, and the additional part 20 has a first side flush with the inner ring surface of the annular structure 14, and there is a predetermined distance between the second side of the additional part 20 arranged opposite to the first side and the outer peripheral surface of the annular structure 14; the outer peripheral surface of the annular structure 14 includes a side surface of the second sealing component 13 facing away from the inner ring surface of the annular structure 14 and a side surface of the first sealing component 12 facing away from the inner ring surface of the annular structure 14; the additional part 20 is arranged radially outside the closing component formed by the first sealing component 12.

[0049] When the annular structure 14 is disposed in the mounting groove 21 , the protruding structures 22 disposed at corresponding positions of the upper shell 15 and the lower shell 16 abut against the additional portion 20 , thereby enhancing the sealing effect of the seal.

[0050] More specifically, an annular mounting groove 21 is provided around the functional component 11, and the inner surface of the annular structure 14 is disposed within the mounting groove 21. The mounting groove 21 ensures that the position of the seal on the functional component 11 remains unchanged, preventing the seal from shifting and affecting the sealing effect between the functional component 11 and the housing.

[0051] In a specific implementation, the additional portion 20 is sleeved on the outer periphery of the functional component 11 via the side wall of the installation groove 21 to perform sealing from the outside of the housing.
