Description

Reliable fixing structure for metal plate shell battery pack

Technical Field

The utility model relates to a reliable fixing structure of a battery pack with a metal plate shell.

Background

The fixed mode of sheet metal shell battery package casing on the existing market is for welding the structure that has the lock and pay the function on the shell, but welded quality and uniformity can't guarantee certainly, and the atress leads to the solder joint to drop very easily in whole car working process, and battery package casing landing causes other major loss of property.

SUMMERY OF THE UTILITY MODEL

The utility model improves the problems, namely the utility model aims to provide a reliable fixing structure of a battery pack with a metal plate shell, which is convenient to use and high in reliability and solves the problem of poor quality of a cold joint or a welding spot caused by welding.

The battery pack comprises a battery pack shell and a plurality of hangers positioned outside the battery pack shell, wherein shell rivets are arranged in the outer wall of the battery pack shell, and each hanger is connected with the shell rivets by adopting a positioning piece.

Furthermore, the hanging lug is provided with two through holes with different sizes for matching with two shell rivets with different diameters.

Furthermore, a U-shaped groove is formed in the lower portion of the hanging lug.

Furthermore, the hangers comprise horizontal parts and vertical parts, the through holes are located on the vertical parts, and the U-shaped grooves are located on the horizontal parts.

Furthermore, the center distance between the two through holes on different hangers is different.

Furthermore, a gasket and an elastic sheet are sleeved on the positioning piece.

Further, the positioning piece is a screw.

Compared with the prior art, the utility model has the following beneficial effects: the device has simple structure and reasonable design, the shell rivet is driven into the position needing to be fixed outside the battery shell body, the two through holes of the hangers are aligned with the two shell rivets, and the hangers are locked inside the shell rivets through the positioning piece; the purpose of fool-proofing and wrong installation is achieved by arranging two through holes on the suspension loop with different diameters and corresponding to shell rivets with different diameters; meanwhile, when hangers with various sizes and models are adopted, the hangers with different center distances between the two through holes are manufactured to distinguish and prevent fool.

Detailed Description

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

Example (b): as shown in fig. 1 to 5, in the present embodiment, a reliable fixing structure for a sheet metal shell battery pack is provided, which includes a battery pack case 1 and four lugs 2 located outside the battery pack case, where two lugs are located in front of the battery pack case, and the remaining two lugs are located at two sides of the battery pack case respectively, a plurality of sets of shell rivets 3 are disposed in an outer wall of the battery pack case, and two shell rivets in each set are used to be matched with corresponding lugs; each suspension loop is connected with the shell rivet through a positioning piece 4, two through holes of the suspension loop are aligned with the shell rivet and sleeved in the shell rivet, and then the suspension loop is locked through two positioning pieces.

The housing rivet has a threaded hole 31 in the middle.

In this embodiment, in order to prevent the hangers from being mistakenly assembled, the hangers are fool-proof, and the hangers are provided with two through holes 21 with different sizes for matching with two housing rivets with different diameters.

In this embodiment, the lower part of the hanging lug is provided with a U-shaped groove 22.

In this embodiment, the hanging lug comprises a horizontal part and a vertical part, the through hole is located on the vertical part, and the U-shaped groove is located on the horizontal part.

In this embodiment, in order to distinguish different hangers and prevent slow-witted, the centre-to-centre spacing between two through-holes on different hangers is different.

The center distance between the two through holes of the hanging lugs positioned in front of the battery shell is 30mm, and the center distance between the two through holes of the hanging lugs positioned on two sides of the battery shell is 33 mm.

In this embodiment, the positioning member is a screw; and a gasket and an elastic sheet are sleeved in the screw.

In the embodiment, during installation, shell rivets are driven into positions of the shell part of the sheet metal battery pack shell, where fixing functions need to be added; bending the hanging lugs and manufacturing through holes according to the hole positions at the fixed positions; the hangers are locked on the shell rivets through the positioning pieces; the hangers are locked on the whole vehicle through screws; and (5) finishing assembly.

When the hangers are installed, if fool-proofing is required, the large holes and the small holes can be matched, namely, the two through holes on one hanger are different in size; if a single battery can shell needs a plurality of hangers of different models, the spacing between holes can be adjusted on the basis of the matching of the big holes and the small holes so as to achieve the fool-proof effect, namely, the center distances between two through holes of the hangers of different models are different.

Any embodiment disclosed herein above is meant to disclose, unless otherwise indicated, all numerical ranges disclosed as being preferred, and any person skilled in the art would understand that: the preferred ranges are merely those values which are obvious or representative of the technical effect which can be achieved. Since the numerical values are too numerous to be exhaustive, some of the numerical values are disclosed in the present invention to illustrate the technical solutions of the present invention, and the above-mentioned numerical values should not be construed as limiting the scope of the present invention.

If the terms "first," "second," etc. are used herein to define parts, those skilled in the art will recognize that: the terms "first" and "second" are used merely to distinguish one element from another in a descriptive sense and are not intended to have a special meaning unless otherwise stated.
