One end of the monitoring and acquisition board 18 extends into the interior of the charging unit 12. The base body 11 has an encapsulation groove 16 inside for injecting thermally conductive adhesive to conduct heat and seal the monitoring and acquisition board 18.

[0019] The waterproof cover assembly 2 includes a waterproof cover body 21 sleeved on the charging part 12, and a sealing gasket 22 is provided inside the waterproof cover body 21 for sealing the charging part 12.

[0020] As a specific technical solution in this embodiment, the base body 11, charging part 12, connecting plate 13 and waterproof cover body 21 are all made of plastic material. The inner walls of the base body 11 are also provided with guide grooves 17 located above the glue potting groove 16 on both sides. The two sides of the monitoring and acquisition board 18 are respectively inserted into the two guide grooves 17. During installation, the monitoring and acquisition board 18 is directly positioned along the guide grooves 17 on the base body 11, which is simple to match, reduces the number of fastening screws, and simplifies the assembly process.

[0021] As a specific technical solution in this embodiment, a connecting plate 13 is also provided between the base body 11 and the charging part 12. The connecting plate 13 is fixedly connected to one side of the panel 3 by screw 133, and the end of the base body 11 away from the connecting plate 13 extends to the other side of the panel 3.

[0022] As a specific technical solution of this embodiment, a sealing groove 131 is provided on one side of the connecting plate 13, and a sealing ring 132 is provided inside the sealing groove 131 for sealing the connection between the connecting plate 13 and the panel 3.

[0023] As a specific technical solution of this embodiment, a screw 181 for locking one end of the monitoring and acquisition board 18 is provided on one side of the charging part 12. A spiral buckle 14 is provided on the charging part 12. The spiral buckle 14 is L-shaped and has a raised rib 15 inside. A positioning block 24 that engages with the spiral buckle 14 is provided on the inner wall of the waterproof cover body 21. The raised rib 15 is located on one side of the positioning block 24. The waterproof cover body 21 and the charging part 12 are designed with a progressive spiral, which makes the fit smooth. The spiral buckle 14 has ribs inside, which can effectively prevent it from falling off due to high-frequency vibration on the car. The waterproof cover assembly 2 and the base assembly 1 are both made of plastic material and have an insertion and removal life of more than 300 times.

[0024] As a specific technical solution in this embodiment, the monitoring and acquisition board 18 has a type-c interface integrated on one end of the charging unit 12. The charging unit 12 has a through hole corresponding to the type-c interface on one side. The monitoring and acquisition module connects to the outside using a conventional type-c interface, which is not limited by the incompatibility of different manufacturers' sockets and plugs, and has strong field applicability.

[0025] As a specific technical solution in this embodiment, the number of spiral buckles 14 and positioning blocks 24 is not less than two. The exterior of the waterproof cover body 21 is also provided with anti-slip texture. The anti-slip texture makes it less likely to slip when rotating the waterproof cover body 21, making it more convenient to use.

[0026] As a specific technical solution in this embodiment, the waterproof cover assembly 2 also includes a hanging rope 23. One end of the hanging rope 23 is connected to the waterproof cover body 21, and the other end is installed on the connecting plate 13. The hanging rope 23 ensures that the waterproof cover body 21 will not fall off after being separated from the charging part 12, making it more convenient to use.

[0027] As a specific technical solution in this embodiment, the end cap 19 of the base body 11, which penetrates the panel 3, is installed with screws 191 to abut the end of the monitoring and acquisition board 18 away from the charging part 12. The bottom of the end cap 19 has a potting port 192 that communicates with the potting groove 16. The end cap 19 is used to fasten the monitoring and acquisition board 18 at the tail of the base body 11 to prevent it from falling off due to vibrations in the car during use. After tightening the end cap 19, thermally conductive adhesive is poured into the potting groove 16 along the potting port 192 reserved on the end cap 19. This can effectively dissipate heat for the chip on the monitoring and acquisition board 18. The thermally conductive adhesive also has a fastening and waterproofing effect on the entire monitoring and acquisition board 18, further improving the requirements of vibration resistance and high protection level of automotive products.

[0028] In use, the monitoring acquisition board 18 is inserted into the base body 11 along the guide groove 17 and extends into the charging section 12. The monitoring acquisition board 18 is then secured with two screws 181. The end cap 19 is then installed on one end of the base body 11 using screws 191, and the monitoring acquisition board 18 is secured. Thermally conductive adhesive is injected into the adhesive filling groove 16 through the filling port 192 at the bottom of the end cap 19. The sealing ring 132 is then inserted into the sealing groove 131. After the adhesive has cured, the assembly of the base assembly 1 is complete. The hanging rope 23 is then fastened to the waterproof cover body 21. The sealing gasket 22 is then inserted into the waterproof cover body 21, completing the assembly of the waterproof cover assembly 2. The positioning block 24 inside the waterproof cover body 21 is opposite to the opening of the spiral buckle 14, pushing the waterproof cover body 21 onto the charging part 12. The positioning block 24 enters the spiral buckle 14 from the opening. When the positioning block 24 touches the corner of the spiral buckle 14, the waterproof cover body 21 is rotated to drive the positioning block 24 to touch the protruding rib 15 and move past the protruding rib 15 to the other side of the protruding rib 15. The protruding rib 15 can effectively lock the positioning block 24, ensuring the assembly stability of the waterproof cover body 21 and completing the sealing protection of the charging part 12. Finally, the connecting plate 13 is fixed to the panel 3 by screw 133 to form a monitoring and acquisition module.

[0029] In summary, this electric vehicle monitoring and acquisition module features a monitoring and acquisition board 18 mounted on the base body 11. This eliminates the need for a separate installation location for the monitoring and acquisition board 18 within the chassis, significantly saving internal space and simplifying the structure. The base and waterproof cover are made of plastic, greatly reducing manufacturing costs. The monitoring and acquisition board 18 uses a standard Type-C interface for external connection, overcoming the incompatibility issues caused by different manufacturers' sockets and plugs, thus offering strong field applicability. The monitoring and acquisition board 18 employs a potting process to increase chip heat dissipation, significantly improving product stability compared to conventional natural heat dissipation. The potting process also enhances the product's shock resistance and IP protection performance, meeting user needs.
