Description

Technical Field

[0001] This utility model belongs to the field of battery pack installation, specifically, it relates to a battery pack installation adapter support structure. Background Technology

[0002] With the continuous development of new energy vehicles, there is a growing demand for converting traditional gasoline vehicles into new energy vehicles. For these conversions, a new front floor is typically developed, while the rear floor is reused or minimally modified to accommodate the battery module underneath the vehicle. The adapter bracket is usually installed in a high-strength location, such as on the rear floor crossbeam or rear floor longitudinal beam. In existing technology, nuts are welded to the brackets. The range of motion in the X and Y directions between the battery pack and the bracket is ensured by the positional accuracy between the through-holes on the battery pack and the bracket. However, improving the positional accuracy of the bracket mounting surface and the bracket nuts on the vehicle body is extremely difficult. Often, the through-holes on the battery pack are enlarged to improve assemblability. However, when the through-holes are large enough to ensure assembly passage, the bolt nuts may not cover the through-holes, leading to detachment and potential danger, and reducing the support force of the bracket.

[0003] To address the aforementioned issues, patent document publication number 109616963A discloses a positioning support for a battery pack and a battery pack having the same. The positioning support is an insulating component and includes a base, a copper busbar limiting groove, and a wire harness limiting part. The copper busbar limiting groove is disposed on the base, and the copper busbar of the battery pack is adapted to pass through and be limited within the copper busbar limiting groove. The copper busbar limiting groove also has an upward opening, and a limiting protrusion is provided at the upward opening. The wire harness limiting part is disposed on the base and is adapted to limit the wire harness of the battery pack. However, this does not solve the aforementioned problems.

[0004] Therefore, in order to improve or solve at least one of the above problems, a battery pack mounting adapter structure is provided that can avoid assembly difficulties, prevent the nut from not covering the mounting through hole due to the mounting through hole being too large, prevent the nut from easily falling off and causing dangerous situations, and prevent the support force of the support from being reduced.

[0020] The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings, in order to help those skilled in the art to have a more complete, accurate and in-depth understanding of the inventive concept and technical solution of the present invention, and to facilitate its implementation.

[0021] Figure 1 This is a schematic diagram of the battery pack mounting adapter structure in an embodiment of this utility model; Figure 2 This is a cross-sectional view of the battery pack mounting adapter structure in an embodiment of this utility model.

[0022] like Figure 1 and Figure 2 As shown, the battery pack mounting adapter support structure provided by this utility model includes a support body 10 disposed on the vehicle chassis. The support body 10 can avoid assembly difficulties, and at the same time, it can avoid the problem that the nut cannot cover the mounting through hole due to the battery pack being too large, thus avoiding the nut being easy to fall off and causing a dangerous situation, and avoiding the problem that the supporting force of the support body 10 is reduced. Therefore, the battery pack mounting adapter support structure provided by this utility model can avoid assembly difficulties, and at the same time, it can avoid the problem that the nut cannot cover the mounting through hole due to the battery pack being too large, thus avoiding the problem that the nut is easy to fall off and causing a dangerous situation, and avoiding the problem that the supporting force of the support body is reduced.

[0023] like Figure 1 and Figure 2 As shown, the support body 10 is provided with a connecting cavity 11, which is located at the top of the support body 10. An anti-loosening nut 20 is provided inside the connecting cavity 11, and the anti-loosening nut is movably disposed within the connecting cavity 11. A limiting groove 12 is provided inside the connecting cavity 11, and a limiting flange 21 is provided on the edge of the anti-loosening nut 20. The limiting groove 12 and the limiting flange 21 are adapted to each other, allowing the anti-loosening nut 20 to be movably locked within the connecting cavity 11. The support body 10 is provided with a connecting through hole 13, which is located above the anti-loosening nut 20, facilitating the connection and assembly of the battery pack. Compared with the fixed-position nuts in the prior art, the battery pack mounting adapter support structure provided in this utility model solves the problem of assembly difficulties and avoids the problem of the anti-loosening nut 20 failing to cover the mounting through hole on the battery pack due to an excessively large mounting through hole, thus preventing detachment and insufficient support.

[0024] The support body 10 is provided with a mounting protrusion 14, which is located at the bottom of the support body 10. The mounting protrusion 14 is provided with a mounting hole 15, and a bolt is inserted into the mounting hole 15, so as to facilitate the installation of the support body 10 on the vehicle chassis.

[0025] The support body 10 is uniformly provided with reinforcing ribs 16, which can enhance the structural strength of the support body 10 and effectively improve the support capacity of the support body 10.

[0026] The battery pack mounting adapter structure provided by this utility model includes a support body 10 mounted on the vehicle chassis. The support body 10 avoids assembly difficulties and prevents the problem of nuts not covering the mounting holes due to excessively large mounting holes on the battery pack, thus preventing the nuts from easily falling off and causing dangerous situations. It also prevents the support force of the support body 10 from being reduced. Therefore, the battery pack mounting adapter structure provided by this utility model avoids assembly difficulties and prevents the problem of nuts not covering the mounting holes due to excessively large mounting holes on the battery pack, thus preventing the nuts from easily falling off and causing dangerous situations, and preventing the support force of the support body from being reduced.

[0027] Compared with the fixed-position nuts in the prior art, the battery pack mounting adapter structure provided in this utility model not only solves the problem of assembly difficulties, but also avoids the problems of the anti-loosening nut 20 not being able to cover the mounting hole on the battery pack due to the mounting hole being too large, thus preventing the problem of falling off and insufficient support.
