Abstract: A universal vehicle-body front end structure, comprising a vehicle body turret, two energy-absorbing box assemblies respectively extending forwards from both lower sides of the vehicle body turret, a front anti-collision beam connected to the two energy-absorbing box assemblies, and a front-end-frame mounting platform, where the front frame installation platform includes two upper beams extending forwards from both upper sides of the vehicle body turret, and two energy-absorbing box brackets respectively arranged on the energy-absorbing box assemblies; the two upper beams and the two energy absorption box brackets are provided with mounting portions; and a plurality of mounting portions form a universal front-end-frame mounting connection port, by means of which various types of front-end frames are mounted.

Abstract: Disclosed are a battery frame, a power battery and a vehicle. The battery frame includes a base plate and side beams. The side beams are provided on opposite sides of the base plate, each side beam includes a side beam part, a connecting part provided inside the side beam part and connected to the base plate, and a fixing part provided outside the side beam part and configured to connect to a door sill beam of a vehicle. The side beam part includes a upper side beam and a lower side beam, the upper side beam is provided above the lower side beam, an outer side of the lower side beam is connected to the fixing part, and an inner side of the lower side beam is connected to the connecting part, and a first cavity is provided at the lower side beam.

Abstract: A ceramic reed switch includes a ceramic tube, and a first end cover and a second end cover, a first pin is disposed on an outer side of the first end cover, a first magnetic reed is disposed on an inner side of the first end cover, the first magnetic reed forms a cantilever beam structure on the first end cover, a second pin is disposed on an outer side of the second end cover, a second magnetic reed is disposed on an inner side of the second end cover, the second magnetic reed forms a cantilever beam structure on the second end cover, free ends of the first magnetic reed and the second magnetic reed are overlapped in the ceramic tube and form an air gap, and a contact is disposed on an overlapped end of the first magnetic reed and the second magnetic reed.
