[0031] The features and exemplary embodiments of various aspects of the present application will be described in detail below. In the detailed description below, many specific details are proposed to provide a comprehensive understanding of the present application. However, it is obvious to those skilled in the art that the present application can be implemented without the need for some of these specific details. The following description of the embodiments is only to provide a better understanding of the present application by illustrating examples of the present application. In the accompanying drawings and the following description, at least some of the known structures and technologies are not shown to avoid unnecessary ambiguity in the present application; and, for clarity, the size of some structures may be exaggerated. In addition, the features, structures or characteristics described below may be combined in one or more embodiments in any suitable manner.

[0032] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply that there is any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that the process, method, article or equipment including a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such process, method, article or equipment. In the absence of more restrictions, the elements limited by the sentence "comprise..." do not exclude the existence of other identical elements in the process, method, article or equipment including the elements.

[0033] The directional words appearing in the following description are all directions shown in the figures, and do not limit the specific structure of this application. In the description of this application, it should also be noted that, unless otherwise clearly specified and limited, the terms "set" and "connect" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected or indirectly connected. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to the specific circumstances.

[0034] With the development of new energy vehicle technology, platform solutions for various new energy vehicle models such as light trucks and small trucks have been promoted. Taking into account the design requirements of long-range driving, the battery pack is placed in the middle of the frame in the existing new energy vehicle design. However, with the subtle adjustments of different models in the platform, the structure, quantity and layout of the battery pack also need to be adaptively changed.

[0035] As a standardized product, the frame is often arranged with preset reserved holes with equal spacing in order to uniformly manage the empty spaces and avoid overlapping openings that affect the structure and performance of the frame. However, the spacing between the installation holes of the battery pack structure itself and the reserved holes on the frame cannot be kept consistent, and the same platform design scheme will also result in slight adjustments to the layout position of the battery pack between the frames.

[0036] Therefore, the existing scheme is designed with an adapter bracket that meets different battery pack design schemes. However, in order to meet the design requirements of matching a variety of different battery pack installation positions with the reserved holes on the frame, it is necessary to design adapter brackets of various specifications and sizes. The sizes and shapes of the various different adapter brackets are very small. While the adapter bracket cannot be fine-tuned to achieve at least partial universality, it is also easy to cause the problem of wrong installation, which affects production efficiency and causes increased management costs.

[0037] To solve the above problems, please also refer to Figure 1 , Figure 2 and Figure 3 , the present application embodiment provides a connection assembly 10 for connecting a vehicle frame 50 and a battery pack 40, see Figure 1 , the connection assembly 10 includes a first bracket 20 and a second bracket assembly 3;

[0038] See also Figure 2 The first bracket 20 includes a first connecting portion 21 and a second connecting portion 22 located at opposite ends along its length direction, and the first connecting portion 21 is used to connect with the frame 50;

[0039] See also Figure 3 The second bracket assembly 3 includes a second bracket 30 or two or more second brackets 30 with different sizes. The second bracket 30 includes a fixed connection portion 31 and an adjustable connection portion 32 distributed along its length direction. The fixed connection portion 31 is used to connect with the battery pack 40. The second bracket 30 can be adjustably connected to the second connection portion 22 of the first bracket 20 through the adjustable connection portion 32.

[0040] See also Figure 1 In the assembled state, the length direction of the first bracket 20 is arranged along the first direction Y, the length direction of the second bracket 30 is arranged along the second direction X, and the first direction Y intersects with the second direction X.

[0041] The connection assembly 10 provided in the embodiment of the present application is provided with a first bracket 20 arranged along a first direction in the length direction in the assembled state and a second bracket 30 arranged along a second direction in the length direction, wherein the connection assembly 10 includes a plurality of second brackets 30 of different sizes. The number, spacing and position of the fixed connection parts 31 and the adjustable connection parts 32 distributed along the length of the second bracket 30 can be specifically set according to the design scheme of different battery packs 40. The spacing of the first connection part 21 and the second connection part 22 distributed along the length of the first bracket 20 can also be specifically set according to different battery packs 40, so as to meet the requirements of the vehicle frame 50 and the vehicle frame 50. The connection requirements of the battery pack 40 in different design schemes are met, and by setting the adjustable connecting part 32, the adjustable space of the connecting component 10 is further increased, which can be arranged according to different vehicle models and platform schemes; at the same time, the first connecting part 21 and the second connecting part 22 of the first bracket 20 and the fixed connecting part 31 and the adjustable connecting part 32 of multiple second brackets 30 of different sizes are all arranged along their own length direction. According to the length difference of the first bracket 20 or multiple second brackets 30, the connecting components 10 in different battery pack 40 design schemes can be distinguished, which is not easy to cause wrong installation, reducing management costs and improving production efficiency.

[0042] The first connecting portion 21 and the second connecting portion 22 are connecting structures required to connect to the reserved holes on the frame 50 and the second bracket 30 respectively.

[0043] Optionally, see Figure 2 The first connection part 21 can be configured as a plurality of connection holes corresponding to the reserved hole pattern on the frame 50, and the connection holes are configured corresponding to the reserved holes and then fixedly connected by bolt connection or riveting;

[0044] The second connection part 22 can be configured as a plurality of connection holes corresponding to the pattern of the fixed connection part 31 , and after the connection holes are configured corresponding to the fixed connection part 31 , they are fixedly connected by bolt connection or riveting.

[0045] The first connection portion 21 and the second connection portion 22 are not limited to being set as connection holes, and the connection method between the first connection portion 21 and the frame 50 is not limited to bolt connection or riveting. The embodiment of the present application only selects this setting method and connection method as an example for the convenience of explanation. The technicians can also select different settings and connection methods for the first connection portion 21 and the second connection portion 22 according to actual needs, and the present application does not limit this.

[0046] The connection assembly 10 includes an assembled state. When the connection assembly 10 is not in the assembled state, the first bracket 20 and the second bracket 30 are disassembled from each other and are generally arranged and stored in their own length direction. The first connection part 21 and the second connection part 22 are arranged along the length direction of the first bracket 20 itself, and the fixed connection part 31 and the adjustable connection part 32 are arranged along the length direction of the second bracket 30 itself. The setting of the functional structure of the first bracket 20 and the second bracket 30 is directly reflected in the length characteristics of the first bracket 20 and the second bracket 30, which is easy to distinguish and convenient to manage.

[0047] When the connecting component 10 is in an assembled state, the first bracket 20 and the second bracket 30 are arranged along the first direction Y and the second direction X. It is also convenient to directly adjust the length of the first bracket 20 or the second bracket 30 to adapt to the requirements of connecting the battery pack 40 and the frame 50 at different installation positions of different battery pack 40 design schemes.

[0048] The second bracket assembly 3 may include only one second bracket 30, or may include two or more second brackets 30 of different sizes. When there are multiple second brackets 30 in the second bracket assembly 3 when not in an assembled state, the second brackets 30 suitable for different battery pack 40 design solutions can be easily distinguished according to the different lengths of the second brackets 30, which is easy to distinguish and convenient to manage; in an assembled state, one second bracket 30 in the second bracket assembly 3 can be selected to be installed in conjunction with the first bracket 20 to meet the installation requirements of different battery pack 40 design solutions.

[0049] In the assembled state, the length direction of the first bracket 20 is consistent with the first direction Y, which is the same direction. Similarly, the length direction of the second bracket 30 is consistent with the second direction X, which is the same direction. When the connecting assembly 10 is not in the assembled state, the length direction of the first bracket 20 is generally consistent with the length direction of the second bracket 30, which is convenient for management.

[0050] See also Figure 1 In the assembled state, the first direction Y intersects with the second direction X, so as to realize a more stable and universal structure of the connection assembly 10. The first direction Y and the second direction X are kept perpendicular to each other. The embodiment of the present application is only for the convenience of explanation and display.

[0052] In these embodiments, the connection assembly 10 provided in the embodiments of the present application, by arranging the two fixed connection parts 31 on the second bracket 30 on both sides of the adjustable connection part 32, makes the force on the entire connection assembly 10 more uniform and the connection more stable, and the adjustable connection part 32 is set as a waist-shaped hole 321, which facilitates the second bracket 30 to be finely adjusted along the second direction X when assembled with the first bracket 20, further increasing the adjustable space of the connection assembly 10, which can be arranged according to different vehicle models and platform solutions.

[0053] Two fixed connection parts 31 are arranged on both sides of the adjustable connection part 32, wherein the two fixed connection parts 31 are respectively connected to the same or two battery packs 40 and are subjected to the gravity of the battery packs 40. The adjustable connection part 32 is connected to the second connection part 22 of the first bracket 20 and is subjected to the pulling force of the first bracket 20. While the gravity of the battery pack 40 and the pulling force of the first bracket 20 are kept consistent, both are evenly distributed on the second bracket 30 along the second direction X, so that the second bracket 30 is subjected to more uniform force in the second direction X and the connection effect is more stable.

[0054] The waist-shaped hole 321 is an oblong hole with its long axis along the second direction X, and a connecting portion is provided between the two semicircular holes. In the embodiment of the present application, the connecting portion is a rectangle with its long side along the second direction X.
