Description

Vehicle Battery Pack Assembly The present invention relates to a battery pack assembly. More specifically, the present invention relates to a battery pack assembly for a vehicle. Some electric trucks (especially pickup trucks) are equipped with an auxiliary battery pack to further increase driving range in addition to the main battery pack provided in the lower part of the vehicle body. Generally, the auxiliary battery pack is mounted on the bed, which is the floor of the vehicle's cargo space. Due to its weight, the auxiliary battery pack mounted on the vehicle's bed is difficult for the user to move manually. In addition, when the auxiliary battery pack is mounted on the vehicle's bed, the size of the cargo space is significantly reduced. FIG. 1 is a cross-sectional view schematically showing the internal structure of a vehicle battery pack assembly according to an embodiment of the present invention. Figure 2 is a drawing showing the first position of a vehicle battery pack assembly. Figure 3 is a drawing showing a second position of a vehicle battery pack assembly. Figure 4 is a schematic diagram showing the lower surface of a rotation unit. Figure 5 is a schematic diagram showing the upper surface of a rotation unit. The technical terms used herein are for the reference of specific embodiments only and are not intended to limit the invention. The singular forms used herein include plural forms unless phrases clearly indicate otherwise. The meaning of "comprising" as used in the specification specifies a particular characteristic, area, integer, step, action, element, and/or component, and does not exclude the presence or addition of other particular characteristic, area, integer, step, action, element, component, and/or group. Unless otherwise defined, all terms used herein, including technical and scientific terms, have the same meaning as generally understood by those skilled in the art to which the present invention pertains. Terms defined in commonly used dictionaries are further interpreted to have meanings consistent with relevant technical literature and the present disclosure, and are not interpreted in an ideal or highly formal sense unless otherwise defined. For example, the term "applied" described below is interpreted to include both the state of being appropriately used and the state prior to being appropriately used. Expressions described in the singular in this specification may be interpreted as singular or plural unless explicit expressions such as "one" or "single" are used. In this specification, terms including ordinal numbers, such as first, second, etc., may be used to describe various components, but said components are not limited by said terms. Such terms are used solely for the purpose of distinguishing one component from another. For example, without departing from the scope of the present disclosure, the first component may be named the second component, and similarly, the second component may be named the first component. In the flowchart described with reference to the drawings in this specification, the order of operations may be changed, several operations may be merged or some operations may be divided, and certain operations may not be performed. Embodiments of the present invention are described below with reference to the attached drawings so that those skilled in the art can easily implement the invention. However, the present invention may be embodied in various different forms and is not limited to the embodiments described herein. FIG. 1 is a cross-sectional view schematically showing the internal structure of a vehicle battery pack assembly (100) according to an embodiment of the present invention. As shown in FIG. 1, the vehicle battery pack assembly (100) includes a first body (110), a second body (120), and a battery (130). Additionally, the vehicle battery pack assembly (100) may further include a rotation unit (140) and cooling channels (111, 112, 121).
