Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0022] like Figures 1 to 8 As shown, an embodiment of the present invention provides a housing assembly, including a housing 1, a charging cable 2, a fixing assembly and a sealing assembly. The housing 1 has an installation cavity 12 inside, and the housing 1 has a through hole 9 communicating with the installation cavity 12. The charging cable 2 includes a first segment 3 and a second segment 4. The first segment 3 extends into the installation cavity 12 through the through hole 9, and the second segment 4 is exposed outside the housing 1.

[0023] The fixing component is disposed between the end of the first segment 3 away from the second segment 4 and the housing 1. The fixing component is used to restrict the movement of the first segment 3 toward the second segment 4 and to restrict the rotation of the first segment 3 around its own axis. The sealing component is disposed between the first segment 3 and the perforation 9.

[0024] In this embodiment, the fixing component can limit the first segment 3 of the cable within the mounting cavity 12, preventing the cable from coming out of the housing 1 and also preventing the cable from rotating. The sealing component can achieve a seal between the first segment 3 and the through hole 9, preventing external debris from entering the mounting cavity 12. No additional screws need to be added to the housing 1, making operation and installation convenient.

[0025] In this embodiment, the first segment 3 enters the mounting cavity 12 from front to back during installation, so that the second segment 4 exits the housing 1 through the perforation 9.

[0026] In this embodiment, the first segment 3 is located at the front end of the charging cable 2, and the second segment 4 is located at the rear end of the charging cable 2.

[0027] In this embodiment, the first segment 3 is used to connect to the charging gun terminal, and the second segment 4 is used to connect to the charging pile.

[0028] In one embodiment, the fixing component includes a pressure ring 5, which has a first mounting hole 15. A first segment 3 passes through the first mounting hole 15, and the inner wall of the first mounting hole 15 is in close contact with the outer peripheral surface of the first segment 3.

[0029] An anti-rotation block 17 is protruding on the outer circumferential surface of the pressure ring 5, and an anti-rotation groove 13 is provided on the inner wall of the mounting cavity 12, with the anti-rotation block 17 snapped into the anti-rotation groove 13.

[0030] In this embodiment, the first segment 3 passes through the first mounting hole 15, the pressure ring 5 is sleeved on the first segment 3, and then the pressure ring 5 is pressed on the first segment 3 by riveting, so that the inner wall of the first mounting hole 15 is in close contact with the outer peripheral surface of the first segment 3, and the first segment 3 cannot move back and forth relative to the pressure ring 5.

[0031] In this embodiment, the anti-rotation groove 13 is recessed into the inner wall of the mounting cavity 12.

[0032] In this embodiment, the housing 1 is provided with a clearance hole 11 at the relative position of the through hole 9. When installing the charging cable 2, the charging cable 2 is inserted into the mounting cavity 12 from front to back through the clearance hole 11, so that the second segment 4 passes out of the housing 1 and the first segment 3 enters the mounting cavity 12. At this time, the anti-rotation block 17 is engaged in the anti-rotation groove 13, so that the first segment 3 can no longer move toward the through hole 9.

[0033] The anti-rotation block 17 contacts the groove wall of the anti-rotation groove 13, and the anti-rotation groove 13 limits the anti-rotation block 17, thereby preventing the first segment 3 from rotating within the mounting cavity 12.

[0034] In this embodiment, the end of the anti-rotation groove 13 away from the through hole 9 extends to the clearance hole 11, so that the anti-rotation block 17 can cooperate with the anti-rotation groove 13 as soon as it enters the mounting cavity 12, which facilitates installation and can also guide the pressure ring 5.

[0035] In one embodiment, there are multiple anti-rotation blocks 17, which are spaced apart around the first segment 3. There are multiple anti-rotation grooves 13, which correspond one-to-one with the anti-rotation blocks 17.

[0036] In this embodiment, "multiple" refers to two or more.

[0037] In this embodiment, multiple anti-rotation blocks 17 are arranged around the first segment 3, and multiple anti-rotation grooves 13 are arranged around the first segment 3. The multiple anti-rotation grooves 13 and multiple anti-rotation blocks 17 are matched one-to-one, which can prevent the pressure ring 5 from losing its anti-rotation function when a certain anti-rotation block 17 breaks, thereby improving the stability of the pressure ring 5.

[0038] In one embodiment, a first stop ring platform 14 is also provided on the inner wall of the mounting cavity 12. The end of the anti-rotation groove 13 away from the pressure ring 5 is connected to the first stop ring platform 14. The first stop ring platform 14 and the anti-rotation block 17 block one side facing the through hole 9.

[0039] In this embodiment, the first stop ring platform 14 protrudes from the inner wall of the mounting cavity 12.

[0040] In this embodiment, the first stop ring platform 14 is arranged around the first segment 3.

[0041] In this embodiment, the first stop ring platform 14 can stop the rotation block 17, preventing the first segment 3 from moving towards the second segment 4 and preventing the first segment 3 from coming out of the mounting cavity 12.

[0042] In one embodiment, a second stop ring platform 16 is provided on the outer peripheral surface of the pressure ring 5, and an anti-rotation block 17 is provided on the second stop ring platform 16. The side of the second stop ring platform 16 facing the through hole 9 is blocked by the side of the first stop ring platform 14 facing away from the through hole 9.

[0043] In this embodiment, the second stop ring platform 16 is arranged around the first segment 3.

[0044] In this embodiment, the second stop ring platform 16 can increase the stopping area between the pressure ring 5 and the second stop ring platform 16, preventing the first segment 3 from detaching from the mounting cavity 12 when the anti-rotation block 17 breaks. This further improves the stability of the pressure ring 5 and the first segment 3 within the mounting cavity 12.

[0045] In one embodiment, the sealing assembly includes a tail sleeve 7, which has a second mounting hole 20. One end of the first segment 3 near the second segment 4 passes through the second mounting hole 20. The inner wall of the second mounting hole 20 is in sealing contact with the outer peripheral surface of the first segment 3. The tail sleeve 7 is located in the gap between the first segment 3 and the through hole 9. The tail sleeve 7 is connected to the housing 1.

[0046] In this embodiment, it can fill the gap between the first segment 3 and the perforation 9, preventing external debris from entering the mounting cavity 12 through the perforation 9.

[0047] In one embodiment, a locking block 25 is provided on the outer peripheral surface of the tail sheath 7, and a locking groove 10 is provided on the inner wall of the through hole 9, with the locking block 25 engaging with the locking groove 10.

[0048] In this embodiment, the slot 10 is recessed on the inner wall of the through hole 9.

[0049] In this embodiment, the side of the locking block 25 facing away from the first segment 3 is provided with a locking slope 26. The distance between the end of the locking slope 26 away from the second segment 4 and the first segment 3 is less than the distance between the end of the locking slope 26 close to the second segment 4 and the first segment 3.

[0050] In this embodiment, a clearance groove 23 is provided on the outer peripheral surface of the tail sleeve 7. A spring arm 24 is provided in the clearance groove 23. One end of the spring arm 24 away from the second section 4 is connected to the side of the clearance groove 23 facing the second section 4. A locking block 25 is provided on the side of the spring arm 24 facing away from the first section 3.

[0051] In this embodiment, during installation, when the tail sleeve 7 is installed from the rear to the front into the through hole 9, the inner wall of the through hole 9 first forces the spring arm 24 to swing towards the first segment 3 to enter the clearance groove 23. When the locking block moves to the position of the locking groove 10, the spring arm 24 swings autonomously away from the first segment 3, so that the locking block 25 enters the locking groove 10, so that the side of the locking block 25 facing the second segment 4 abuts against the side of the locking groove 10 away from the second segment 4.

[0052] In this embodiment, the outer peripheral surface of the tail sleeve 7 is in close contact with the inner wall of the perforation 9, and the friction between the outer peripheral surface of the tail sleeve 7 and the inner wall of the perforation 9 prevents the tail sleeve 7 from detaching from the perforation 9 on its own.

[0053] In one embodiment, the sealing assembly further includes a tail waterproof ring 6, which has a third mounting hole 18. The first segment 3 passes through the third mounting hole 18, and the inner wall of the third mounting hole 18 is in sealing contact with the outer peripheral surface of the first segment 3. The tail waterproof ring 6 is connected to the tail sheath 7.

[0054] In this embodiment, the tail waterproof ring 6 is located on the side of the tail sheath 7 facing away from the second section 4.

[0055] In this embodiment, the tail waterproof ring 6 has a positioning hole 19 on one side facing the tail sheath 7, and the tail sheath 7 has a positioning post 22 protruding on one side facing the tail waterproof ring 6. The positioning post 22 is inserted into the positioning hole 19, and the outer peripheral surface of the positioning post 22 is interference-fitted with the inner wall of the positioning hole 19, so that the positioning post 22 cannot be disengaged from the positioning hole 19, thereby realizing the connection between the tail waterproof ring 6 and the tail sheath 7.

[0056] In this embodiment, the tail sheath 7 has a weight reduction hole 21 on the side facing the tail waterproof ring 6.

[0057] In one embodiment, the sealing assembly further includes a tail cap 8, which has a fourth mounting hole 29. One end of the second segment 4 near the first segment 3 passes through the fourth mounting hole 29, and the inner wall of the fourth mounting hole 29 is in sealing contact with the outer peripheral surface of the second segment 4.

[0058] The tail cover 8 is connected to the tail sleeve 7, and the side of the tail cover 8 facing the pressure ring 5 is blocked by the end face of the housing 1 facing the tail cover 8.

[0059] In this embodiment, both the tail sleeve 7 and the tail cap 8 are plastic parts with a certain degree of elasticity.

[0060] In this embodiment, the outer peripheral surface of the end of the tail that is away from the pressure ring 5 is provided with an insertion ring platform 27. The outer peripheral surface of the insertion ring platform 27 is an insertion slope. The distance between the end of the insertion slope that is away from the pressure ring 5 and the first segment 3 is less than the distance between the end of the insertion slope that is close to the pressure ring 5 and the first segment 3.

[0061] In this embodiment, the tail cap 8 is provided with a plug-in cavity 30 communicating with the fourth mounting hole 29 on the side facing the pressure ring 5. A third stop ring platform 31 is provided at the opening of the plug-in cavity 30. The side of the third stop ring platform 31 facing away from the pressure ring 5 and the side of the plug-in ring platform 27 facing the pressure ring 5 are stopped.

[0062] In this embodiment, a guide block 32 protrudes from the inner wall of the insertion cavity 30, and a guide groove 28 is provided on the insertion ring platform 27. The guide block 32 is inserted into the guide groove 28, which can play a guiding role when the insertion ring platform 27 is inserted into the insertion cavity 30, making it easy to install.
