As it was previously stated, auxiliary battery pack 120 is primarily to meeting the demand of farther continual mileage and setting, this part
The ratio that continual mileage accounts in the Life cycle of vehicle be no more than 10%, therefore auxiliary battery pack 120 select high energy than electricity
Core so that battery pack in groups after continual mileage can freely arrange in pairs or groups according to vehicle demand.Preferably, the circulation of auxiliary battery pack 120
Service life meets the requirement of the cycle life (80%) of the 1C charge and discharge of more than 800 times.In this way, main battery bag 110 and auxiliary battery pack
120 can both meet the needs of driver is for trip, eliminate mileage anxiety, but can reduce power battery pack integral into
This, enhances vehicle competitiveness.
In this present embodiment, first fixing device 130 includes some fixed locks 131, passes through the fixed lock
131 are fixed on the main battery bag 110 on the chassis runner 210.The fixed lock 131 is, for example, but is not limited to following
Structure:Latch, lock pin etc., lock groove is provided with the latch, and lock groove both sides are locking buckles.Described
One fixing device 130 can also use any fixed knot being fixed on battery pack on Vehicle Controller of the prior art
Configuration formula.
In this present embodiment, second fixing device 140 forms a Quick battery-changing device, as shown in Figures 2 and 3,
The auxiliary battery pack 120 can be fixed in the frame body 141 by the lock piece of second fixing device 140,
When needing to remove the auxiliary battery pack 120 from electric automobile, the lock piece is opened, the auxiliary battery pack 120 can take off
From the frame body 141, the dismounting of the auxiliary battery pack 120 is more simple.
Specifically, in this present embodiment, the lock piece of second fixing device 140 includes:To be mutually locked
One lock piece and the second lock piece;First lock piece, on the frame of the frame body 141;Second locking
Part is sealed with first lock piece and is connected with the chassis runner 210.
In this present embodiment, as shown in Figures 2 and 3, first lock piece and the second lock piece are respectively to latch and lock
One kind and another kind in body.The structural style of the lock is, for example, to latch 142a, lock 142c, the structure sample of the lock body
Formula is, for example, lock body 142b, lock body 142d.
For example, the lock body is arranged in the first side opposite with frame body 141 of chassis runner 210;The lock is set
In on the frame body 141, and the second side opposite with the first side;Or the lock body is arranged on the frame body
On 141, the second side opposite with the chassis runner 210;And the lock is arranged on the chassis runner 210, and with it is described
The opposite first side of second side.
Wherein, when that need to install or replace the auxiliary battery pack 120, the frame body 141 drive it is described lock towards
The lock body movement, makes the lock fasten with the lock body, into lockup state;Needing to change the auxiliary battery pack 120
When, the frame body 141 drives the lock to be moved towards the direction away from the lock body, makes the lock and the lock body shape
Into released state.In this present embodiment, the lock body is arranged in the first side opposite with frame body 141 of chassis runner 210,
The lock is arranged on the frame body 141, and the second side opposite with the first side.
Wherein, the lock body can be divided into upper lock body and down lock body, and the upper lock body and down lock body are rotated by a stopper section
Formula connects.Pivoted connects a tight lock part, the side of the tight lock part and an elasticity between the down lock body and the stopper section
One end (in the present embodiment, which refers to the lower end of elastic component) of part mutually mounts, and the other end of the elastic component is (in the present embodiment
In, the other end refers to the upper end of elastic component) it is mounted on the upper lock body.In the present embodiment, the elastic component uses metal elastic
Spring.
Lock tongue and slot are provided with the tight lock part.
