Detailed Description

The following detailed description of specific embodiments of the present disclosure is provided in connection with the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating the present disclosure, are given by way of illustration and explanation only, not limitation.

Unless stated to the contrary, the terms "upper", "lower", "top" and "bottom" as used in this disclosure are used with respect to the actual state of use of the relevant component. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated.

Referring to fig. 1 and 2, the present embodiment provides a power battery clamp, which is used for fixing a battery box of a power battery during air tightness detection, and includes a pressing plate 1 for abutting against an upper surface of the battery box, the pressing plate 1 is connected with a mounting bracket for bearing the battery box through a fastener, and a supporting member for supporting the pressing plate 1 is disposed between the pressing plate 1 and the mounting bracket.

Through the technical scheme, the pressing plate 1 in the clamp is abutted against the upper surface of the battery box, so that the battery box is prevented from deforming due to unbalanced gas pressure in the process of detecting the air tightness of the battery box, and the structural integrity of the battery box is ensured; support clamp plate 1 through setting up support piece to prevent that the weight direct action of clamp plate 1 from the battery box upper surface, cause the battery insulation trouble, foretell power battery anchor clamps simple structure, and convenient to carry can protect the structural integrity of battery box in gas tightness testing process well.

Referring to fig. 2, in the embodiment of the present disclosure, two ends of the pressing plate 1 are respectively provided with a positioning hole 11 for the fastener to pass through and corresponding to the mounting hole of the mounting bracket, for positioning and connecting the power battery, the supporting member may be a sleeve 4 sleeved on the fastener and located between the pressing plate 1 and the mounting bracket, so that the supporting member is more stable, the material of the sleeve 4 may be steel, which can bear certain supporting strength, and further, the height of the sleeve 4 may be set according to the distance between the upper surface of the mounting bracket of the battery box and the pressing plate 1. In other embodiments, the supporting member may be configured in any suitable manner, and may serve to support the pressure plate 1, which falls within the protection scope of the present disclosure.

Specifically, the outer diameter of the sleeve 4 is larger than the diameter of the mounting hole, so that the sleeve 4 can be fixed between the pressure plate 1 and the mounting bracket, preventing the sleeve 4 from falling off from the mounting hole.

Further, the fastener may be the bolt 2, and in other embodiments, the fastener may also be configured as a pin, a screw, etc., all falling within the scope of the present disclosure.

As an exemplary embodiment of the present disclosure, referring to fig. 1 and 2, the power battery clamp may further include a bottom plate 5 penetrating through the bolt 2, the bottom plate 5 is fixed at the bottom end of the mounting bracket through a nut 3, and since a connection portion between the bottom end of the mounting bracket and the bolt 2 is formed with a large opening, the nut 3 may penetrate through the opening in a small size, and the mounting bracket cannot be locked, the nut 3 may lock the mounting bracket conveniently by setting the bottom plate 5, and since the bottom plate 5 needs to bear a certain strength, steel may be selected for use.

Further, locating hole 11 department can be equipped with the gasket, and like this, when bolt 2 passed locating hole 11, the gasket can bear partly pressure, avoids leading to clamp plate 1 extrusion deformation because of pressure is too big, and specifically, the material of gasket can be steel.
