[0002] In related technologies, the grounding wire of the existing battery box is mostly installed at the front or rear of the battery pack. This requires additional welding of mounting brackets or protrusions, and the use of wicking nuts on the mounting brackets or wire thread inserts nested in the protrusions to fix the grounding wire. This increases the number of parts and results in higher installation costs for the grounding wire. Furthermore, installing the grounding wire at the front or rear of the battery pack requires installers to move to the front or rear of the battery pack to install the grounding wire during battery box installation, increasing the range of movement for installers and reducing the installation efficiency of the grounding wire. Utility Model Content

[0003] The present invention aims to at least solve one of the technical problems existing in the prior art.

[0027] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0028] The following is for reference. Figures 1-3 The side beam assembly 100 of the battery box and the battery box body are described according to embodiments of the present invention.

[0029] like Figures 1-3 As shown, the side beam assembly 100 of the battery box according to an embodiment of the present utility model includes: a side beam 10, the side beam 10 having an installation notch 11 extending through the side beam 10 along its height direction, the installation notch 11 being located at the middle position of the side beam 10 along its length direction, the installation notch 11 having an installation part 12, the installation part 12 being fixedly connected to the side beam 10, and a grounding connector 20 being installed on the installation part 12.

[0030] The side beam 10 has an installation notch 11 extending through it along its height. Along its length, the notch 11 is located at the center of the side beam 10. Specifically, any position between the two ends of the side beam 10 can be considered the center. The specific location of the installation notch 11 can be reasonably set according to actual conditions. For example, it can be selected based on the location of other components that need to be avoided, as well as the location of the grounding connector 20, as long as the installation notch 11 is located at the center of the side beam 10. The installation notch 11 being located at the center of the side beam 10 allows the force at the notch 11 to be evenly distributed across the side beam 10, thereby reducing the risk of damage to the side beam 10 due to excessive localized stress. In addition, the installation notch 11 formed in the side beam 10, which runs through the side beam 10 along its height direction, can reduce the weight of the side beam 10 while ensuring its strength, thereby reducing the weight of the battery box. At the same time, the installation notch 11 can also serve as a collapse area for the side beam 10, improving the collapse performance of the side beam assembly 100 and reducing the risk of the side beam assembly 100 being squeezed into the battery cells inside the battery box by side impact, thereby improving the safety and reliability of the battery box.

[0031] The mounting notch 11 contains a mounting portion 12, which is fixedly connected to the side beam 10. For example, the mounting portion 12 and the side beam 10 can be integrally formed, or they can be fixedly connected by welding. However, this utility model is not limited to these methods; the mounting portion 12 and the side beam 10 can also be fixedly connected in other ways, as long as they are fixedly connected. This application uses the integral forming of the mounting portion 12 and the side beam 10 as an example. Since the mounting portion 12 and the side beam 10 are integrally formed, there is no need to set connecting parts at the front or rear end of the battery box. This not only reduces the number of parts but also improves the connection stability between the mounting portion 12 and the side beam 10, thereby reducing the risk of the mounting portion 12 detaching from the side beam 10.

[0032] The grounding connector 20 may include a grounding wire harness, a grounding terminal, etc. The grounding connector 20 is installed on the mounting part 12. For example, the grounding connector 20 and the mounting part 12 can be connected by bolts, or the grounding connector 20 and the mounting part 12 can be connected by snap-fit. However, this utility model is not limited to this. The grounding connector 20 and the mounting part 12 can also be connected in other ways, as long as the grounding connector 20 is installed on the mounting part 12. This can ensure the electrical connection between the battery box and the ground, avoid leakage and electric shock hazards caused by insulation problems, and provide safety for drivers and passengers.

[0033] Therefore, by forming an installation notch 11 in the side beam 10, and having an installation part 12 within the installation notch 11, with the installation part 12 integrally formed with the side beam 10, the grounding connector 20 is installed in the installation part 12 of the side beam 10. This eliminates the need for additional components for installing the grounding connector 20 at the front or rear of the battery box, reducing the number of components required for installation and lowering the installation cost of the grounding connector 20. Furthermore, the installation part 12 is located on the side beam 10, placing it within the fastening operation range of the battery box, allowing the installation of the grounding connector 20 to be completed without moving the work area, thus improving the installation efficiency of the grounding connector 20. Additionally, the installation part 12 on the side beam 10 enables the installation of grounding connectors 20 for vehicles with different wheelbases on the same platform, thereby improving the compatibility of the vehicle production line.

[0034] According to some embodiments of the present invention, such as Figure 2 As shown, along the length of the side beam 10, the mounting part 12 can be located at one end of the mounting notch 11. For example, the mounting part 12 can be located at any end of the mounting notch 11. The specific location of the mounting part 12 can be selected according to the position of other components that need to be avoided and the location of the grounding connector 20. As long as the mounting part 12 is located at one end of the mounting notch 11, it is sufficient. By setting the mounting part 12 at one end of the mounting notch 11, the installation position of the grounding connector 20 can be more easily controlled and adjusted, making the installation process of the grounding connector 20 more intuitive and convenient. This makes it easier for installers to identify the installation position of the grounding connector 20, which not only reduces installation time and labor costs but also improves the installation accuracy of the grounding connector 20. This helps ensure the tightness and stability of the connection between the grounding connector 20 and the mounting part 12, reducing performance problems caused by installation errors.

[0035] According to some embodiments of the present invention, such as Figure 2 As shown, the mounting section 12 may include a mounting plate 13. The grounding connector 20 is fixed to the mounting plate 13 by fasteners 30, such as bolts or screws. The design of the mounting plate 13 makes the installation process of the grounding connector 20 more intuitive and convenient. Installers can intuitively identify the installation position and use the fasteners 30 to fix the grounding connector 20 to the mounting plate 13, thereby saving installation time and labor costs. By firmly fixing the grounding connector 20 to the mounting plate 13 with the fasteners 30, the connection strength between the grounding connector 20 and the mounting plate 13 can be ensured, helping to prevent the grounding connector 20 from loosening or falling off during use, thus improving the stability and reliability of the overall structure. Furthermore, this design eliminates the need for other components in the battery housing for installing the grounding connector 20, reducing the number of components and thus lowering the installation cost of the grounding connector 20.

[0036] According to some embodiments of the present invention, such as Figure 3 As shown, the fastener 30 can be a flow drill screw. The flow drill screw softens the connected parts through high-speed rotation and finally tightens the self-tapping screw, forming a high-strength connection with excellent tensile and shear strength. It can also achieve a single-sided connection with minimal deformation, reducing the thickness requirement of the mounting plate 13 and helping to reduce material costs while maintaining structural strength and stability. This helps ensure that the grounding connector 20 remains intact under external forces, preventing loosening or detachment. Furthermore, the installation process of the flow drill screw is relatively simple, helping to reduce installation time and labor costs, and improving overall installation efficiency. The flow drill screw directly rotates through the mounting plate 13 during installation to fasten the grounding connector 20 without the need for pre-drilling, thus simplifying the installation steps of the grounding connector 20 and minimizing damage to the mounting plate 13, helping to maintain the integrity and aesthetics of the mounting plate 13, while also reducing waste and debris generated during installation.

[0037] According to some embodiments of the present invention, such as Figure 2 and Figure 3 As shown, the mounting plate 13 may have a positioning hole 14, and the grounding connector 20 may have a positioning flange 21, which is fitted into the positioning hole 14.

[0038] The positioning hole 14 and the positioning flange 21 are matched in shape and size so that the positioning flange 21 can be smoothly assembled into the positioning hole 14. The matching design of the positioning hole 14 and the positioning flange 21 can ensure that the grounding connector 20 is accurately positioned on the mounting plate 13, which can reduce the risk of positional deviation of the grounding connector 20 during installation, thereby improving the installation accuracy of the grounding connector 20. Furthermore, through precise positioning, it can ensure that the connection between the grounding connector 20 and the mounting plate 13 is more stable, reducing the risk of failure caused by improper installation.

[0039] In addition, the cooperation between the positioning flange 21 and the positioning hole 14 makes the installation process simpler. The installer only needs to insert the positioning flange 21 into the positioning hole 14 to complete the positioning and initial fixation of the grounding connector 20, thereby ensuring that the connection between the grounding connector 20 and the mounting plate 13 is simpler and more reliable, reducing failures caused by loose connections and helping to extend the service life of the equipment.

[0040] According to some embodiments of the present invention, such as Figure 2 and Figure 3 As shown, the edge of the mounting plate 13 may have a limiting notch 15 that extends through the mounting plate 13 along the height direction of the side beam 10, and the grounding connector 20 forms a limiting structure 16, which is assembled into the limiting notch 15.

[0041] The limiting structure 16 can be a crimping structure for the wire harness and terminal in the grounding connector 20. The shape and size of the limiting notch 15 and the limiting structure 16 can be adapted so that the limiting structure 16 can be smoothly assembled into the limiting notch 15. The cooperation between the limiting notch 15 and the limiting structure 16 provides a clear reference for the positioning of the grounding connector 20 on the mounting plate 13, which can ensure that the grounding connector 20 can quickly and accurately find its predetermined position during installation, avoiding deviations and errors in the assembly process.

[0042] Furthermore, with the cooperation of the limiting notch 15 and the limiting structure 16, and the cooperation of the positioning hole 14 and the positioning flange 21, it can be further ensured that the grounding connector 20 can quickly and accurately find its predetermined position during installation, avoiding deviations and errors in the assembly process, thereby further ensuring the reliability and stability of the connection between the grounding connector 20 and the mounting plate 13.

[0043] According to some embodiments of this utility model, the thickness of the mounting plate 13 is D, satisfying the relationship: 1mm ≤ D ≤ 4mm. That is, the thickness D of the mounting plate 13 can be any value between 1mm and 4mm, for example, 1mm, 2mm, 2.5mm, 3mm, 4mm, etc. However, this utility model is not limited to this; the thickness D of the mounting plate 13 can also be other values ​​between 1mm and 4mm, as long as the thickness D of the mounting plate 13 satisfies the relationship: 1mm ≤ D ≤ 4mm. The thickness D of the mounting plate 13 satisfying the relationship: 1mm ≤ D ≤ 4mm makes the mounting plate 13 more flexible during processing, easier to cut, drill, and bend, and also meets the strength and rigidity requirements of the mounting plate 13, ensuring that the mounting plate 13 is not easily deformed or damaged during installation and use. The specific value of the thickness D of the mounting plate 13 can be reasonably set according to actual conditions.

[0044] Furthermore, the mounting plate 13 can be formed by extrusion of aluminum alloy or by stamping and roll forming of high-strength steel. When the mounting plate 13 is formed by extrusion of aluminum alloy, its thickness D can satisfy the relationship 2mm ≤ D ≤ 4mm, for example, the thickness D of the mounting plate 13 can be 2mm or 4mm. When the mounting plate 13 is formed by stamping and roll forming of high-strength steel, its thickness D can satisfy the relationship 1mm ≤ D ≤ 1.5mm, for example, the thickness D of the mounting plate 13 can be 1mm or 1.5mm. The manufacturing material and thickness of the mounting plate 13 can be reasonably selected according to the actual situation.

[0045] According to some embodiments of the present invention, such as Figure 2As shown, along the height direction of the side beam 10, the height of the upper surface of the mounting part 12 is lower than the height of the upper surface of the side beam 10. The side beam 10 can be formed by stacking and connecting three layers of plates in sequence. The mounting part 12 can be part of the middle layer plate, so that the height of the upper surface of the mounting part 12 is lower than the height of the upper surface of the side beam 10. This arrangement can achieve reasonable functional zoning, help to distribute the load on the mounting part 12, reduce stress concentration caused by concentrated loads, and thus improve the safety and reliability of the grounding connector 20. It can be explained that the side beam assembly 100 can include the frame body 40 and the side beam 10. The side beam 10 is connected to one side of the frame body 40, and the height of the upper surface of the side beam 10 is lower than the height of the upper surface of the frame body 40. This arrangement can realize the installation of the grounding connector 20 for different wheelbase models on the same platform, which is beneficial to improving the versatility of the mounting part 12, thereby improving the compatibility of the vehicle production line and reducing the development cost of the parts used to install the grounding connector 20.

[0046] According to some embodiments of the present invention, such as Figure 2 As shown, along the length of the side beam 10, the side beam 10 has a protruding structure that protrudes into the mounting notch 11, and the protruding structure is configured as a mounting part 12.

[0047] Along the length of the side beam 10, the side beam 10 has a protruding structure extending into the mounting notch 11. This protruding structure serves as a mounting part 12. The mounting part 12 and the side beam 10 can be integrally formed. This integral design makes the connection between the mounting part 12 and the side beam 10 more robust and avoids the need for a connecting structure between them. This reduces the number of parts and consequently lowers the installation cost of the grounding connector 20. The side beam 10 can be formed by stacking three layers of plates sequentially. The mounting part 12 is part of the middle layer. The mounting part 12 can be a protruding structure extending into the mounting notch 11 relative to the upper plate of the side beam 10. Alternatively, a portion of the upper plate of the side beam 10 can be removed so that the mounting part 12 is exposed below the upper plate. This allows the mounting part 12 to be located within the mounting notch 11 and visible to the installer, enabling them to see the surrounding environment of the mounting part 12 for precise operation and adjustment.

[0048] According to the battery box of this utility model embodiment, including the side beam assembly 100 of the battery box of the above embodiment, there is no need to set other parts in the battery box for installing the grounding connector 20, which can reduce the number of parts for installing the grounding connector 20, which is beneficial to reducing the installation cost of the grounding connector 20. In addition, the mounting part 12 is set in the side beam 10 so that the mounting part 12 is within the fastening operation range of the battery box, and the installation of the grounding connector 20 can be completed without moving the working area, which is beneficial to improving the installation efficiency of the grounding connector 20. Furthermore, the mounting part 12 being set in the side beam 10 can realize the installation of the grounding connector 20 for vehicles with different wheelbases on the same platform, thereby improving the compatibility of the vehicle production line.
