Description

Vehicle-mounted electric vehicle battery quick replacement device and replacement method

Technical Field

The invention relates to the technical field of new energy electric automobiles, in particular to a vehicle-mounted quick battery replacing device for an electric automobile and a replacing method thereof.

Background

At present, pure electric vehicles obtain a long-term development, but the quantity and the distribution of the facility of charging are difficult to satisfy the demand that increases day by day, and the charge time is also the key factor that restricts pure electric vehicles development for a long time, and the form that the battery change mode continued a journey as a quick replenishment has also been paid attention to, but the fixed form of vehicle power battery on the vehicle at present uses bolt fastening mostly, the battery structure of each vehicle is different, the specification is not unified, the motorcycle type of different brands can not use same set of trades electrical equipment, and trade electrical equipment and need the integrated mechanism of dismantling and installing fastening battery, have with high costs and the poor defect of commonality, therefore trade the electrical mode and hardly popularize at present.

Disclosure of Invention

In order to overcome the defects of the conventional battery replacement mode, the vehicle-mounted device for rapidly replacing the battery of the electric automobile is used for achieving the function of rapidly loosening and tightening the battery of the automobile and has a self-locking function to prevent the battery from being abnormally loosened and falling. The vehicular automatic dismounting device is simple in structure, integrated on a vehicle, the operation process of fastening and releasing the battery can be rapidly completed through vehicle software control, the equipment of the battery replacing station does not need to directly participate in the tightness process of the battery, the equipment of the battery replacing station only needs to realize the reference positioning of the battery and can support and lift functions, when the structure of the vehicle battery changes, the equipment of the battery replacing station does not need to be updated, the input cost of the battery replacing station is saved, the universality of the battery replacing station is improved, and the vehicle provided with the rapid dismounting system can carry out battery replacing operation in the battery replacing station.

The technical scheme is as follows: the invention designs a vehicle-mounted device for rapidly replacing a battery and a replacement method. The device realizes being connected of battery and frame through arranging bayonet lock and bayonet lock groove complex device between battery and frame, including bayonet lock groove, slip bayonet lock, guide rail, flexible lock catch, axial driver, realizes the fixed of battery on the frame by the cooperation of bayonet lock and bayonet lock groove, and the bayonet lock has certain direction angle with the fitting surface in bayonet lock groove, plays the guide effect. The battery replacement method comprises the following steps: in the process of installing the battery, the axial driver drives the bayonet lock to move forwards, so that the bayonet lock is attached to the bayonet lock groove, and meanwhile, the telescopic locking pin rises to prevent the bayonet lock from returning, and the process of installing the battery is finished; in the process of disassembling the battery, the telescopic locking pin descends, and the axial driver drives the clamping pin to move backwards, so that the clamping pin is disconnected with the clamping pin groove, and the battery is separated from the frame. The bayonet lock can be matched with the bayonet lock groove in two modes, one mode is a matching mode of a trapezoidal boss pin and a trapezoidal groove, the mode is a multi-surface matching mode, the contact area is large, the stress is good, the other mode is a matching mode of a conical pin and a conical hole, the mode is an arc surface matching mode, the centering performance is good, and the positioning is convenient. The form of the axial telescopic driver can be selected into two schemes of a hydraulic cylinder form and a worm and gear servo motor driving screw rod form, the hydraulic driving has the characteristics of low cost and convenient control, and the worm and gear servo motor driving has the advantages of self locking and high stability.

Has the advantages that: the electric vehicle of this vehicular battery quick replacement device of installation will realize the quick fastening and the release operation process of battery by self, and the equipment of trading the power station need not directly participate in the elasticity operation process of battery and frame, and only need carry out benchmark location, support and lift operation to the battery, therefore when the structure of own of battery and frame structure change, the equipment that trades the power station does not need hardware to be updated, trades power station equipment input cost low. This vehicular quick assembly disassembly system simple structure, it is little to the change of frame, and the cost of increase is few, and the system has self-locking function, has guaranteed the stability of the battery fastening of vehicle. The other effect of this system is when battery unusual overtemperature appears in electric automobile, before the battery spontaneous combustion takes place, to battery and frame disconnection, then when putting out a fire to electric automobile, can drag the automobile body earlier when putting out a fire to electric automobile, puts out a fire to the battery alone, and it is efficient to put out a fire to reduce the body loss of vehicle, protected personnel's in the car personal safety simultaneously.
