Problems solved by technology
[0003] The research on the key parts technology (motor, battery, electronic control) of electric vehicles is becoming more and more mature, and the degree of industrialization is increasing day by day. However, the research on the battery locking mechanism is still insufficient in terms of meeting the working conditions and convenient operation. The requirements for vibration are becoming more and more stringent. In the prior art, the locking mechanism uses a buffer device composed of a single bolt to connect with the battery box. Unable to shield multi-directional vibration, unable to meet the working condition requirements of GB / T31467.3-2015

Embodiment Construction
[0015] A preferred embodiment of the present invention will be described in detail below with reference to the accompanying drawings.
[0016] Such as figure 1 As shown, the power battery box locking system includes a mounting base 10, a locking mechanism 20 and a buffer device 30, the power battery box is connected to the locking mechanism through the buffer device, and the locking mechanism can lock the buffer device, The locking mechanism is fixed on the mounting base by bolts.
[0017] The mounting base 10 is processed by Q235A, with a thickness of 3 mm. The flange structure and rib structure are respectively made in the X, Y, and Z directions. The flange width is greater than 30 mm. The mounting base adopts a left and right open closed structure, and the closed surface Extend the flange by more than 30mm to transmit the force in this direction, and connect with the locking mechanism and the power battery box through bolts.
[0018] Such as figure 2 As shown, the locki...

The invention provides a locking system for a power battery box. The locking system comprises an installation base, a locking mechanism and a buffering device. The locking mechanism is installed on the installation base and connected with the power battery box through the buffering device. The buffering device comprises three buffer bolts distributed in parallel triangularly and a triangular fixing board used for fixing one end of each buffer bolt. The other end of each buffer bolt is connected with a buffer pad. By the adoption of the locking system, the buffering device composed of the triangular bolts is used for being connected with the battery box and the locking mechanism, vibration in three directions can be effectively counteracted, the vibration resistant capacity of a lock body is improved, and an impact effect on the lock body due to traditional single bolt fixing is reduced.
Description
technical field [0001] The invention relates to the technical field of lithium batteries, in particular to a battery case locking system structure for power battery modules, which can be used by electric vehicles after the battery modules and battery systems are assembled and tested. Background technique [0002] Transportation energy and environmental issues are major challenges facing the world at present, and are also the crux of the problem that restricts the sustainable development of the automobile industry. Therefore, major automobile companies and scientific research institutions continue to increase the research and development of electric vehicles, and governments of various countries have also formulated various measures to promote the development of electric vehicles. The promotion of new energy vehicles has greatly promoted the development of electric vehicles. Compared with traditional fuel vehicles, electric vehicles have zero emissions. They not only repl...
