DETAILED DESCRIPTION

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0019] like Figure 1-3As shown: A battery pack charge and discharge port assembly, including a sealing cover 1 installed on the opening side of the new energy battery housing, the sealing cover is cast and formed by resin material, and also has a handle assembly, the upper side of the sealing cover 1 has a step groove 10, and the side wall corresponding to the step groove 10 is provided with a mounting hole 11, and the charging and discharging interface assembly 2 is installed in the mounting hole 11;

[0020] The charge and discharge interface assembly 2 includes a mounting plate 21, which is installed flush with the mounting hole 11. The mounting plate completely covers the mounting hole. One side of the internal space of the sealing cover is the main body. The other side of the mounting plate 21 is provided with a charging port 23 and a discharging port 24, respectively. The charging port 23 and the discharging port 24 both extend into the main body. The inner grooves of the charging port and the discharging port are provided with various power connection holes or terminals, as well as data line connection holes for data connection. The terminals and the tail ends of the components are integrated in the main body and located inside the sealing cover. The tail of the main body has various cables connected to the main line board for connecting new energy batteries. The sealing cover is not only used for sealing, but also has a protective effect.

[0021] The charging and discharging interface assembly of the utility model is an integrated structure, and the integrated charging port and discharging port are the same part. The corresponding sealing cover only needs to open one mounting hole, and the installation of the charging and discharging interface is completed at the same time during installation, which saves installation space and time, simplifies the installation process of the battery assembly, and improves production efficiency.

[0022] like Figure 1-2 As shown: the charge-discharge interface assembly 2 is installed inside the sealing cover 1, and the sealing cover 1 has a guide wall 12 for sliding installation on the side of the mounting plate 21 corresponding to the side of the mounting hole 11, and the guide wall 12 has an extension section 13 outside the corresponding mounting hole 11. The charge-discharge interface assembly is installed by sliding along the guide wall inside the sealing cover until the charge-discharge interface assembly is flush with the end of the guide wall, and the installation is completed, which is not only convenient for installation, but also improves the stability of the charge-discharge interface assembly.

[0023] Existing charging and discharging interface components are all installed externally. The installation sequence is to install the charging and discharging interface components first, and then connect the corresponding main body parts. Since the line contains multiple data lines and current lines, the wiring is complicated and easy to be connected incorrectly.

[0024] The installation method disclosed by the utility model is that the charging and discharging interface assembly is installed from the inside to the outside, the wiring of the tail end of the main body can be carried out first, and then the installation holes are aligned, which simplifies the operation process.

[0025] The end of the guide wall 12 has an inner buckle edge 14 for limiting the mounting plate 21. The inner buckle edge design can limit the position of the mounting plate, while improving the sealing between the guide wall and the mounting plate to prevent dust and rainwater from entering the interior. The mounting plate 21 has conical protrusions on both sides, and the inner buckle edge 14 has a covering part at the position where the conical protrusion is located. The covering part and the conical protrusion have corresponding openings and are fixed by bolts. It is used to fix the charge and discharge interface assembly to prevent the interface assembly from falling off when plugging the charge and discharge connector.

[0026] This specification selects and specifically describes these embodiments in order to better explain the principles and practical applications of the present invention, so that those skilled in the art can better understand and utilize the present invention.
