One end on edge fit.Strengthening support is set to play better booster action, lifting lug load degree is higher.
On the basis of any one of the above scheme, the triangular support body is right angled triangle frame body.
The hangers is L shape, and one side edge of L shape hangers is connected with inclination connection side, and another side extends downwardly.When lifting
Suspender belt is hooked on the downside on one side that L shape hangers is connected with inclination connection side, the another side and inclination connection side of L shape hangers
Block is carried out to suspender belt from two sides, to prevent suspender belt slippage, safety is more preferable.
The lifting lug is an integral molding structure.It avoids at link position there are stress concentration phenomenon, guarantees that lifting lug is whole
Structural strength with higher.
The battery case of the utility model adopts the following technical scheme that
A kind of battery case, including cabinet and the intracorporal battery modules of case are mounted on, lifting lug, lifting lug packet are equipped on the outside of cabinet
Include triangular support body, triangular support body includes that the vertical connection that is fixedly connected with wall box is upper while vertically connecting
The inclination of end connection connects side, and inclination connection is equipped with hangers in upper side while backwards to vertical connection.Triangular support body itself
Stability is preferable, vertically connects side and is fixedly connected with the wall box of battery case, and diagonal bracing effect is played on inclination connection side, thus
It ensure that lifting lug structural strength with higher and load degree, ensure that the higher reliability and safety of battery case.
Further, the hangers is on inclination connection side close to medium position.It can make lifting lug entirety stress in this way
More evenly, it avoids lifting lug stress serious uneven and is pulled from cabinet.
Further, vertical connect between when tilting connection is connected with strengthening support.Further improve the knot of lifting lug
Structure intensity.
When hangers close medium position on inclination connection side, vertical connect between when tilting connection is connected with
Strengthening support, and strengthening support is connected to hangers and tilts the position of connection side connection.Further increase lifting lug structural strength and
Load degree.
Further, strengthening support is obliquely installed, and the one end being connected on inclination connection side is higher than and is connected to and vertically connects
One end on edge fit.Strengthening support is set to play better booster action, lifting lug load degree is higher.
On the basis of any one of the above scheme, the triangular support body is right angled triangle frame body.
The hangers is L shape, and one side edge of L shape hangers is connected with inclination connection side, and another side extends downwardly.When lifting
Suspender belt is hooked on the downside on the one side being connected with inclination connection side of L shape hangers, and the another side of L shape hangers and inclination connect
While carrying out block to suspender belt from two sides, to prevent suspender belt slippage, safety is more preferable.
The lifting lug is an integral molding structure.It avoids at link position there are stress concentration phenomenon, guarantees that lifting lug is whole
Structural strength with higher.
