Furthermore, the end part of the handle is connected with the sliding groove in a sliding mode through a fixing shaft.

Furthermore, both sides of the accommodating groove extend outwards to form a handle slot position.

Further, the lithium battery module shell comprises an upper shell and a lower shell.

Furthermore, an upper half chute is arranged on the upper shell; the lower shell is provided with a lower half chute; the upper half sliding groove and the lower half sliding groove are symmetrically arranged and form a sliding groove when the upper shell is matched with the lower shell.

Furthermore, the side wall end face of the upper shell or the lower shell is circumferentially provided with a waterproof glue groove.

Furthermore, the end of the handle is located two when the spout is farthest relatively, the handle is flush with the end face of the lithium battery module shell where the handle is located.

Third, beneficial effect

The utility model has the beneficial effects that:

1. the handle installation is convenient fast. The handles are placed in the corresponding clamping grooves before the upper shell and the lower shell are assembled, and the handles are installed after the upper shell and the lower shell are locked, so that other accessories and operation are not needed;

2. has no influence on the waterproof function of the shell. Because the concave space is relatively independent from the shell waterproof structure, the original waterproof structure of the shell cannot be damaged. The waterproof glue groove and the limiting slide way for installing the lifting handle are of two independent structures;

3. the handle has proper tensile strength in the use process, cannot be pulled out easily and has good reliability. The fixed axle of handle moves in spacing slide, and when the handle was lifted, two fixed axles of handle slided to the relative nearest department of two slides, and the handle forms a space that can lift by hand. Due to the accurate control of the assembly size, the handle is limited properly, and the reliability of normal use is good unless violently pulled;

4. the cost is low. As a main accessory, the lifting handle has simple structure, low cost and low assembly cost; 5. the overall dimension of the battery is not greatly increased, and the appearance of the battery is regular. No additional size or profile is created.

Detailed Description

For the purpose of better explaining the present invention and to facilitate understanding, the present invention will be described in detail by way of specific embodiments with reference to the accompanying drawings.

The hidden handle of the lithium battery module shell according to one embodiment of the utility model, as shown in fig. 1-3, comprises a handle 2 arranged on a lithium battery module shell 1; the lithium battery module shell 1 is provided with a sliding groove which is formed by inner concave parts and is in sliding connection with the two end parts of the handle 2; the two slide grooves are provided with a limiting part 31 which limits the sliding of the handle 2 at the relatively nearest position.

In an embodiment of the present invention, a holding groove 4 for holding the handle 2 is disposed in the middle of the two sliding grooves.

In an embodiment of the present invention, the end of the handle 2 is slidably connected to the chute through a fixed shaft 6.

In an embodiment of the present invention, the two sides of the accommodating groove 4 extend outward to form a handle groove 41, and the handle 2 can be conveniently taken through the handle groove 41.

In an embodiment of the present invention, the lithium battery module housing 1 includes an upper case 11 and a lower case 12.

In an embodiment of the present invention, the upper shell 11 is provided with an upper half chute 111; the lower shell 12 is provided with a lower half chute 121; first spout 111 sets up and forms the spout with second spout 121 symmetry when epitheca 11 and inferior valve 12 cooperation, and through the spout that epitheca 11 and inferior valve 12 formed of mutual butt joint, can be convenient carry out the installation of handle 2 in the installation casing, save the process, fixed axle 6 card can accomplish the installation in the spout when installing the casing.
