  • Publication number: 20240367528
    Abstract: An electric all-terrain vehicle includes a set of wheels, a drive system, a battery pack, and an MCU. A projection of the MCU, a projection of the battery pack, and a projection of the electric motor all on a horizontal plane cooperatively define a Tri-core system projection area with a Tri-core longitudinal length. A ratio of the wheelbase distance to the Tri-core longitudinal length is in the range from 0.7 to 2.5. The positions of the Tri-core system are reasonably arranged and the relevant components are highly integrated, the center of gravity of the entire vehicle are reasonably allocated, thereby making the overall performance of the vehicle more superior and achieving better driving performance.

  • Patent number: 11177544
    Abstract: A battery device includes a case, a cell disposed within the case, and first and second conductive tabs each electrically connected to the cell and partly enclosed by the case. The first conductive tab has an elastic portion exposed from the case and compressible or stretchable when a force is applied thereto. By having the elastic portions that are elastically deformable, the effects of push or pull resulting from the swelling of the cell and case on the conductive tabs may be reduced. Consequently, damages or breakages of the conductive tabs can be avoided and the safety of battery device may be improved.

  • Patent number: 10942059
    Abstract: The present invention discloses an online method for metering performance of a diaphragm gas meter. A magnetic turntable in an electromechanical conversion device is reasonably segment and motion information of each segment is recorded and analyzed. Every time when the diaphragm gas meter discharges gas of a rotary volume, a rotating shaft of a meter core rotates a circle. The magnetic turntable is meshed with a driving gear output by the rotating shaft in the meter or output by the rotating shaft outside the meter to ensure that the magnetic turntable rotates a circle every time when the diaphragm gas meter discharges a rotary volume. The present invention is significant for error management of the gas meter and intelligent control and gas utilization safety management of a gas user.
