[0037] Please refer to Figures 1 to 6 In one embodiment, to solve the problem that the busbar clamp 20 is unstable in butt joint with the power supply busbar (not shown in the figure) and has a short service life, the utility model provides a busbar clamping mechanism 100, which comprises: a conductive frame body 10, a busbar clamp 20 and a driving mechanism 30, the busbar clamp 20 is arranged on the conductive frame body 10, the busbar clamp 20 comprises a busbar clamp plate 21 and a conductive sheet 22, the conductive sheet 22 is arranged on the inner side wall of the busbar clamp plate 21, at least a part of the conductive sheet 22 is elastic, and the driving mechanism 30 is arranged on the outer side of the busbar clamp plate 21;Wherein, the busbar clamp plate 21 and the conductive sheet 22 are both arranged in two, and the driving mechanism 30 is used for driving the two busbar clamp plates 21 to approach or move away from each other, so as to drive the two conductive sheets 22 to approach or move away from each other.The busbar clamping mechanism 100 provided by the utility model compared with prior art, when the busbar clamp 20 and the power supply busbar are in butt joint process, if there is some deviation in the busbar clamp 20, the elastic conductive sheet 22 deforms elastically to adapt to the position of the power supply busbar, so that the busbar clamp 20 and the power supply busbar are not affected by internal force during butt joint process, and the service life of the busbar clamp 20 is increased.

[0038] In one embodiment, the conductive sheet 22 comprises: a clamping portion 221, an elastic portion 222 and a connecting portion 223, both ends of the elastic portion 222 are connected with the clamping portion 221 and the connecting portion 223 respectively.The elastic portion 222 has elasticity, can fine-tune the form of the conductive sheet 22, the clamping portion 221 is a rigid structure, can increase the contact area of the conductive sheet 22 and the branch busbar;The connecting portion 223 is also a rigid structure, so that the operator can install the conductive sheet 22 on the stand column 40.

[0040] Of course, the column 40 and the base can also be integrally formed, which is not limited by the specific definition of the specific embodiment.

[0041] In one embodiment, the busbar clamp 20 adopts a pair of busbar clamp plates 21. That is, the two sides of the busbar clamp plate 21 of a part of the busbar clamp 20 are respectively provided with a driving mechanism 30 and a series oil cylinder 23. And the busbar clamp 20 is controlled to be clamped and released by controlling the oil pressure of the driving mechanism 30 and the series oil cylinder 23. The two sides of another part of the busbar clamp 20 are both provided with a series oil cylinder 23, and the clamping and release of the busbar clamp 20 are controlled by the oil pressure of the two series oil cylinders 23.

[0042] In the traditional power transmission vehicle, the pair of busbar clamps each have two push oil cylinders, and the design of the two push oil cylinders makes the structure of the busbar clamp 20 too complex and the use cost too high.
