In the related art, in a battery BOX for mounting a backup battery in a vehicle-mounted T-BOX, an elastic member is disposed in the BOX body, and the battery is elastically supported by the elastic member, so that the manufacturing tolerance of the backup battery is adapted by the elastic deformation of the elastic member. However, this requires calculating the compression amount and the rebound force of the elastic member according to the tolerance band analysis of the backup battery, and requires a plurality of trial-and-error processes to determine the final scheme, which results in high product design cost. Moreover, the manufacturing tolerance range of the adaptable backup battery in the related art is small, and replacement of the backup battery in the later period is not facilitated.

To above-mentioned technical problem, this application embodiment provides a hold box, including box body and lid, and box body and lid link to each other through first connecting portion and second connecting portion. And the second connecting part comprises a plurality of connecting sub-parts connected with the first connecting part, and the plurality of connecting sub-parts are distributed along the covering direction of the box body and the cover body. Therefore, the distance between the cover body and the bottom of the box body can be adjusted by connecting the first connecting portion to different connecting sub-portions, so that the accommodation box can be adapted to mount workpieces of different sizes. And the manufacturing tolerance of the spare battery does not need to be measured and calculated in the design process, and the spare battery is trial-manufactured for multiple times, so that the design cost of accommodation is favorably reduced.

The following describes the technical solutions of the present application and how to solve the above technical problems with specific embodiments. These several specific embodiments may be combined with each other below, and details of the same or similar concepts or processes may not be repeated in some embodiments. Embodiments of the present application will be described below with reference to fig. 1 to 15.

In some alternative embodiments, as shown in fig. 1 to 3, the accommodation box provided by the present application includes a box body 100 and a cover body 200. The box 100 is a basic structure, and can provide an installation space and an installation foundation for the workpiece 300. In addition, the case 100 may provide a mounting base for the cover 200.

Referring to fig. 2, 11 and 12, in some alternative embodiments, one of the case 100 and the cover 200 has a first connection portion 210, and the other has a second connection portion 110 corresponding to the first connection portion 210.

As shown in fig. 1 to 3, in some alternative embodiments, the first connecting portion 210 is disposed on the cover 200. The second connecting portion 110 is disposed on the case 100. As shown in fig. 9 to 11, in other alternative embodiments, the first connecting portion 210 may be further disposed on the box 100, and the second connecting portion 110 is disposed on the cover 200.

Further alternatively, the second connection part 110 has a plurality of connection sub-parts 111 distributed in the first direction. Referring to fig. 2, 8 and 11, in a state where the cover 200 is fitted to the case 100, the cover 200 is overlapped with the case 100 in the first direction, and the first connection part 210 is detachably connected to at least one of the connection sub-parts 111 of the corresponding second connection part 110. Illustratively, the first direction may be the direction indicated by the z-axis in FIG. 1.

In the above embodiment, the second connecting portion 110 has a plurality of connecting sub-portions 111 distributed along the first direction. Therefore, one first coupling portion 210 can be coupled to different coupling portions 111, respectively, to adjust the relative positions of the cover 200 and the case 100. During the installation of the workpiece 300, the relative positions of the workpiece 300 and the box 100 in the first direction can be adjusted, so that accommodating spaces with different sizes are formed between the cover 200 and the box 100 to accommodate the workpieces 300 with different sizes in the first direction.

In some alternative embodiments, as shown in fig. 2, 4 and 5, the cassette 100 has a receiving cavity 103, and the receiving cavity 103 is used for mounting the workpiece 300.

Referring to fig. 5, in some alternative embodiments, the dimension of the receiving cavity 103 in the first direction is less than or equal to the dimension of the workpiece 300 in the first direction. Illustratively, in a state that the workpiece 300 is installed in the accommodating cavity 103, at least a part of the workpiece 300 extends beyond the accommodating cavity 103, so that a side of the cover 200 close to the box 100 is abutted against a side of the workpiece 300 away from the box 100.

In some alternative embodiments, as shown in fig. 4 and 5, the inner side wall of the accommodating cavity 103 is provided with a limiting column 120, and the limiting column 120 protrudes out of the inner side wall of the accommodating cavity 103. With the workpiece 300 in the receiving cavity 103, the workpiece 300 is supported by the restraint posts 120.

In the above embodiment, in the case where the workpiece 300 is mounted in the accommodating chamber 103, the limiting posts 120 may abut against the outer peripheral wall of the workpiece 300 to prevent the workpiece 300 from moving in the direction perpendicular to the first direction. In addition, the limiting column 120 protrudes out of the inner side wall of the accommodating cavity 103, so that the inner side wall of the accommodating cavity 103 is prevented from being completely attached to the outer peripheral wall of the workpiece 300, and a buffer space is formed between the outer peripheral wall of the workpiece 300 and the inner side wall of the accommodating cavity 103.

Illustratively, in the case that the box body 100 is pressed externally, the sidewall of the box body 100 is deformed in the accommodating cavity 103 after being pressed. Because the buffer space is arranged between the inner side wall of the accommodating cavity 103 and the outer peripheral wall of the workpiece 300, the extrusion force applied to the side wall of the box body 100 can be prevented from being directly transferred to the workpiece 300, and therefore, the protection of the workpiece 300 in the accommodating cavity 103 is facilitated.

Referring to fig. 4, in some alternative embodiments, one side of the cassette body 100 in the first direction has a loading and unloading port 104, the loading and unloading port 104 communicates with the accommodation chamber 103, and the workpiece 300 is loaded into or removed from the accommodation chamber 103 along the loading and unloading port 104. Optionally, the loading/unloading opening 104 is oriented in the first direction. Specifically, the lid 200 covers the attachment/detachment port 104. In some alternative embodiments, the retaining post 120 is disposed on the inner sidewall of the receiving cavity 103 along the first direction.

In the above embodiment, the workpiece 300 can slide in the accommodating cavity 103 along the surface of the limiting column 120 facing away from the side wall of the accommodating cavity 103 in the process of being assembled to the accommodating cavity 103, so that it is beneficial to smoothly assemble the workpiece 300 into the accommodating cavity 103.

Optionally, the limiting column 120 extends from the loading/unloading opening 104 to the bottom of the accommodating cavity 103 along the inner sidewall of the accommodating cavity 103. In some further alternative embodiments, as shown in FIG. 15, a second guide surface 121 is provided on the spacing post 120. Optionally, the second guiding surface 121 is located on a side of the restraint post 120 near the loading/unloading opening 104. Further optionally, the second guide surface 121 is disposed by inclining the side of the limiting column 120 departing from the inner side wall of the accommodating cavity 103 to the side close to the inner side wall of the accommodating cavity 103. For example, in the process of assembling the workpiece 300 to the accommodating cavity 103, an included angle between the second guide surface 121 and the direction in which the limiting column 120 moves relative to the workpiece 300 is an obtuse angle, so as to reduce the alignment difficulty of assembling the workpiece 300 to the accommodating cavity 103.

In some alternative embodiments, as shown in fig. 3 and 4, the box body 100 is provided with a wire through hole 204, and the wire through hole 204 penetrates through the cavity wall of the box body 100 and is communicated with the accommodating cavity 103. Optionally, the workpiece 300 mounted in the cartridge 100 includes a wire 310. Optionally, the lead 310 may extend out of the receiving cavity 103 along the wire passing hole 204.

Illustratively, the workpiece 300 may be a battery. Specifically, the lead 310 connected to the battery can pass through the accommodating cavity 103 along the wire passing hole 204.

In other alternative embodiments, the cover 200 is provided with a wire through hole 204, and the wire through hole 204 penetrates through the cover 200 and communicates with the accommodating cavity 103, so that the lead wire 310 connected with the workpiece 300 can pass through the accommodating cavity 103 along the wire through hole 204.
