In addition, features defined as "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present utility model, unless otherwise specified, "multiple" means two or more.

[0041] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" 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 a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0042] Unless otherwise specified, the front-to-back direction in the present application is the longitudinal direction of the vehicle, that is, the X direction; the left-right direction is the lateral direction of the vehicle, that is, the Y direction; and the up-down direction is the vertical direction of the vehicle, that is, the Z direction.

[0043] Reference below Figure 1-Figure 12 A battery pack installation assembly 100 according to an embodiment of the present invention is described. The battery pack installation assembly 100 can achieve efficient, stable and reliable installation of the battery pack 7, ensure the safety and stability of the battery pack 7, and has a simple structure, convenient installation and high space utilization.

[0044] like Figure 1-Figure 12 As shown, the battery pack installation assembly 100 according to an embodiment of the utility model includes: two longitudinal beams 1 and a bracket assembly 2.

[0045] The two longitudinal beams 1 are spaced apart in the transverse direction, that is, the two longitudinal beams 1 are spaced apart from each other in the transverse direction of the vehicle by a certain distance, and serve as the main support frame of the battery pack installation assembly 100, for supporting and installing the battery pack 7, and ensuring the installation stability of the battery pack 7. The battery pack 7 can be installed between the two longitudinal beams 1, which is beneficial to the heat dissipation of the battery pack 7 and improves its heat dissipation performance. When the vehicle collides, the two longitudinal beams 1 can absorb vibration, protect the battery pack 7, and reduce the impact on the battery pack 7, thereby reducing damage to the battery pack 7 and improving its safety.

[0046] The bracket assembly 2 is used to connect and fix the battery pack 7 and the two longitudinal beams 1. In other words, the battery pack 7 is connected and fixed between the two longitudinal beams 1, wherein the two longitudinal beams 1 are provided with bracket assemblies 2 on the sides facing each other, that is, the two longitudinal beams 1 can be installed with bracket assemblies 2 on the opposite sides, so that the left and right sides of the battery pack 7 can be connected and fixed to the two longitudinal beams 1 through the bracket assembly 2. In this way, the battery pack 7 is avoided from being directly installed on the longitudinal beam 1, and a certain distance is separated from the two longitudinal beams 1, providing a certain buffer space for it, preventing the battery pack 7 from directly contacting and colliding with the longitudinal beam 1, further reducing the damage to the battery pack 7, and is beneficial to improving its heat dissipation performance, while facilitating the installation and removal of the battery pack 7.

[0047] The bracket assembly 2 includes a first bracket 21, a second bracket 22 and a third bracket 23, which are spaced apart and distributed along the front-to-back direction and are all provided with a connection portion 4 for connecting with the battery pack 7. That is, by three connection brackets spaced apart and distributed on the longitudinal beam 1 along the front-to-back direction, multiple installation support points and positioning points can be provided for the battery pack 7, so that the battery pack 7 can be more stably installed on the two longitudinal beams 1, and it is not easy to shake or deflect, thereby improving its stability and safety. Moreover, the three brackets are all provided with a connection portion 4 for connecting with the battery pack 7, that is, the bracket can be firmly connected with the battery pack 7 through the connection portion 4, so that the bracket and the battery pack 7 can be prevented from being separated, and the installation reliability of the battery pack 7 can be ensured. Moreover, the connection through the connection portion 4 can make the installation simpler and more accurate, and when the battery pack 7 needs to be repaired or replaced, it is convenient to remove the battery pack 7, which is flexible and convenient. In actual design, the connection portion 4 can be set as a connection hole, and a connector is inserted therein to realize the fixed connection between the bracket assembly 2 and the battery pack 7.

[0048] The first bracket 21 and the third bracket 23 are each provided with at least one connection portion 4, that is, the first bracket 21 and the third bracket 23 may be provided with one, two, three or even more connection portions 4, the length of the second bracket 22 is greater than the length of the first bracket 21 or the third bracket 23, and the second bracket 22 is provided with at least two connection portions 4, that is, the second bracket 22 may be provided with two, three or even more connection portions 4, and by providing multiple connection portions 4, multiple fixed connection points can be provided to connect with the battery pack 7, which can improve the connection stability and reliability between the battery pack 7 and the bracket assembly 2. Among them, since the installation position of the second bracket 22 is located in the middle position of the battery pack 7, the length of the second bracket 22 is set longer, so that the support points of the battery pack 7 in the middle position can be increased, so that the battery pack 7 can be installed on the bracket assembly 2 more stably.

[0049] Therefore, the battery pack 7 can be fixedly connected to the two longitudinal beams 1 through the first bracket 21, the second bracket 22 and the third bracket 23 of the specific structure, so as to achieve stable and reliable installation of the battery pack 7, ensure the safety and stability of the battery pack 7, make full use of the space between the two longitudinal beams 1, and improve space utilization.

In actual design, the upper connecting flange 2112 and the first connecting flange 2121 can be connected to the upper side surface and the inner side surface of the longitudinal beam 1 by welding.

[0056] Therefore, by setting the upper connecting flange 2112 and the first connecting flange 2121, a stable and reliable connection between the first bracket 21 and the longitudinal beam 1 can be achieved, thereby improving the connection strength and rigidity between the two, thereby facilitating improving the installation stability of the battery pack 7.
