Embodiment Construction

[0028] The present invention will be further described below in conjunction with the embodiment represented by accompanying drawing:

[0029] Such as Figure 1-7 As shown, this embodiment discloses a lifting device for the battery compartment 20 of an electric vehicle, which is used to change the height of the battery compartment 20 to expose the battery and facilitate the battery grabbing mechanism to grab and replace the battery. The bottom of rack 10.

[0030] The lifting device for the battery compartment 20 of the electric vehicle includes a first lifting mechanism 34 and a second lifting mechanism 35 arranged at symmetrical intervals along the center line of the battery compartment 20. Both lifting mechanisms include a sliding assembly and a swing arm 32; the swing arm 32 is located on the vehicle. between the frame 10 and the battery compartment 20, and have opposite translation ends and rotation ends, the translation ends are fixedly connected with the sliders of the ...

Abstract

The invention discloses an electric vehicle battery compartment lifting device which comprises a first lifting mechanism and a second lifting mechanism, and the two lifting mechanisms each comprise a sliding assembly and a swing arm; the sliding assembly is in driving connection with the driving mechanism, the swing arm is arranged between the frame and the battery bin, and the battery bin is hung below the frame through the swing arm. The two swing arms are provided with opposite translation ends and rotating ends, the translation ends and the rotating ends have height difference, the translation ends of the two swing arms are fixedly connected with the sliding parts of the same sliding assembly, the rotating ends of the two swing arms are hinged to the frame at intervals, and the two swing arms are symmetrically arranged along the center line of the battery bin and can synchronously swing between the initial positions and the unfolding positions in a reciprocating mode. The lifting stability and accuracy of the battery compartment can be improved, the lower space of the vehicle body can be fully utilized, and the effective lifting stroke of the battery compartment can be obtained in the limited vertical space.

Description

technical field [0001] The invention belongs to the technical field of electric vehicles, and in particular relates to a lifting device for a battery compartment of an electric vehicle. Background technique [0002] Most electric vehicles are powered by the driving battery pack installed at the bottom of the vehicle. In order to reduce the waiting time for charging, electric vehicles mostly use battery replacement technology. The battery grabbing device is used at the battery replacement station to replace the driving battery of the electric vehicle as a whole. However, in order to ensure For the safety of electric vehicles, the driving battery is installed in the battery compartment and hidden under the car body, which is not conducive to the battery grabbing device to grab and replace the battery. The pick-up device can grab and replace the battery from the side. Existing battery compartments mostly use mutually hinged scissor arms to achieve lifting. The scissor arms are...
