Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

As shown in fig. 1-9, an aluminum barrel capable of fixing a battery pack comprises an aluminum barrel body 10 and a battery pack 20 located in the aluminum barrel body, wherein a clamping support rib 30 fixed inside the aluminum barrel body is arranged inside the battery pack, two ends of the aluminum barrel are provided with openings, at least one end of the aluminum barrel is fixedly connected with a baffle 40 capable of closing the openings, the clamping support rib 30 is located on two sides of the upper portion and the lower portion of the battery pack, and a shell of the battery pack is provided with a pressing surface which extends to contact with the clamping support rib.

In this embodiment, the upper portion and the lower part of the shell both sides of group battery 20 extend there is otic placode 210, chucking support rib 30 sets up in the upper portion and the lower part both sides of group battery respectively to the application two sets ofly, the length of chucking support rib 30 needs the design according to the actual length of group battery, otic placode 210 corresponds chucking support rib 30 and sets up in this embodiment, the otic placode upper surface that is located group battery shell upper portion supports the rib cooperation with the chucking and forms the face that compresses tightly, thereby the otic placode lower surface that is located group battery shell lower part supports the position that the rib cooperation formed the spacing group battery of face that compresses tightly with the chucking.

In this embodiment, the inner side surface of the baffle 40 is provided with the reinforcing ribs 410, so that the strength of the baffle can be enhanced, and the baffle 40 is used for realizing the end sealing of the aluminum barrel body to ensure the lower support or the upper sealing of the battery.

In addition, in this embodiment, the fixing strip 110 is fixed in the aluminum barrel body, bolt holes 111 are formed at both ends of the fixing strip 110, the baffle plate 40 is connected to the aluminum barrel body through screws 112 penetrating through the baffle plate 40 and the bolt holes 111, limiting convex portions 120 protruding inward are formed on both sides of the inner wall of the aluminum barrel body 10, and the limiting convex portions 120 are used for assisting in limiting the position of the battery pack inside.

During the installation, the back is packed into from aluminium barrel head portion to the group battery, and the face structure that compresses tightly of group battery contacts spacingly with the chucking support rib, and after the position was assembled to, the group battery opposite side was the on-state, passes through the fix with screw with baffle and aluminium bucket, still have on the baffle can with group battery fixed connection's locking screw, form a fixed whole.

This patent aluminium bucket can be used to full encapsulating battery scheme, also can be used to half encapsulating battery scheme, still can be used to ordinary group battery design scheme. The applicability is strong, and the structural strength is good.
