It is moved up and down in power shell, guide post is equipped with damping spring 4, and when damping framework moves down, damping spring will be by
Compression.
Battery unit is arranged in damping framework, and damping framework is equipped with several positioning strips 18, parallel cloth between positioning strip
It sets, battery unit is fixed on positioning strip, thus by the bottom of battery unit and damping framework spaced apart from surfaces.In the middle part of positioning strip
Parting bead equipped with protrusion, to by battery unit in damping framework arranged for interval, there are gaps between adjacent battery unit.
Damping framework is equipped with several straight slots, and the position of straight slot and the interstitial site of battery unit are corresponding, between being flowed through in order to air
Gap takes away heat.
The lower part of damping framework is equipped with the cooling fin 12 of several parallel arrangements, and upper end and the rotation of damping framework of cooling fin connect
It connects, and the upper end of cooling fin is below damping framework upper surface.Damping framework is equipped with supporting rack, and supporting rack includes interior bull stick 14
With outer bull stick 17, the right end of damping framework and the upper end of interior bull stick are rotatablely connected, the upper end of the left end of damping framework and outer bull stick
The lower end of rotation connection, interior bull stick extends to the left side of power shell, and the lower end of outer bull stick extends to the right side of power shell, interior
Bull stick and outer bull stick are arranged in X-shaped.The inner wall of power shell is equipped with horizontal sliding slot 10, and the both ends of sliding slot are respectively equipped with sliding block
11, sliding block is in sliding fit with the sliding chute.The sliding block rotation connection of the lower end and left side of interior bull stick, the lower end of outer bull stick and the cunning on right side
Block is rotatablely connected.When damping framework opposed power shell moves down, supporting rack pushes sliding block to be moved along sliding slot.
The lower section of damping framework is equipped with from moving frame 13, is arranged in parallel from moving frame and damping framework, the lower end of cooling fin with from
Moving frame is rotatablely connected, damping framework, cooling fin and from forming parallelogram sturcutre between moving frame.Rotation is equipped in power shell
The madial wall of block 16, moving block and power shell is rotatablely connected.The position of moving block is corresponding with the middle part from moving frame, moving block and
Positioning pin 15 is equipped between inner wall, inner wall is coordinated equipped with regulating tank with positioning pin.Moving block is equipped with inclination arrangement
Skewed slot 16a, in the present embodiment, the left side of the upper end of skewed slot to power shell.It is equipped with from moving frame and is slidably matched with skewed slot
Sliding pin, when being moved up and down from moving frame from the sliding pin of moving frame along skewed slot slide so that can be moved left and right from moving frame.
As shown in Fig. 2, the both ends of sliding slot are respectively equipped with fixed block 6, side of the block in the middle part of power shell is set
Limit spring 5 can be equipped with relative to the limited block 9 that sliding slot moves by having between limited block and block.Damping framework is moved down damping bullet
After spring compression, when sliding block still continues to move to block, limited block can be with shoe contact to compress limit spring, damping at this time
Spring and limit spring collective effect provide restoring force, so that sliding block can stop and move backward reset as early as possible.
It is fixed with translating rack 9a on limited block, pinion gear 21, pinion gear and upper translating rack are equipped in power shell
Cooperation transmission, pinion gear lower section are equipped with lower translating rack 19.The medial surface of power shell is equipped with ventilation opening 2a and can cover
The cowl flap 20 of ventilation opening, the upper end of cowl flap and the medial surface of power shell are rotatablely connected, and lower translating rack is equipped with guide groove
19a, cowl flap are equipped with the spacer pin 20a that is slidably matched with guide groove, and lower translating rack is pushed to when moving inside power shell
Cowl flap rotates, and ventilation opening is opened.
After battery unit is installed to damping framework, due to self gravitation effect, damping framework moves down the damping of compression lower section
Spring, while making cooling fin and declining from moving frame, so that being located at the middle part of skewed slot from the sliding pin of moving frame, radiate at this time
Piece is in vertical or close to vertical state.When remaining static, relies primarily on cooling fin itself heat-transfer capability and dissipated
Heat.During power supply moves use, power shell is given a shock, and the battery unit in power shell is opposite due to inertia
Power shell vertical displacement drives cooling fin to move up and down.
As shown in figure 3, when damping framework moves down, cooling fin and also move down from moving frame, is being moved down from moving frame therewith
In the process, the lower end movement of sliding pin down fold, moves right from moving frame by skewed slot guiding role thus while moving down,
Cooling fin rotates an angle counterclockwise relative to damping framework, and distance reduces between abutting fins, thus will be between cooling fin
Air extrude；It when damping framework moves up, cooling fin and is also moved up therewith from moving frame, the middle part of sliding pin down fold is moved
It is dynamic, it is moved to the left at this time from moving frame by skewed slot guiding role thus while moving up, cooling fin is with respect to damping framework up time
Needle is rotated to vertical position, and distance increases between abutting fins, to draw air between cooling fin；When damping framework
When moving up further, cooling fin and also moved up simultaneously from moving frame, the upper end movement of sliding pin down fold, at this time from moving frame by
Thus continue to be moved to the left while moving up to skewed slot guiding role, cooling fin is rotated clockwise with respect to damping framework, adjacent
Distance reduces between cooling fin, to extrude the air between cooling fin.When damping framework moves back and forth up and down, drive from
Moving frame or so swings back and forth, while making cooling fin also reciprocating rotation, in conjunction with cooling fin itself capacity of heat transmission to continuous power supply
Heat is distributed to outside in shell, reduces the temperature of battery unit.
When vibration amplitude increases, the displacement of damping framework increases so that sliding block is further towards the end of sliding slot, sliding block
Contact limited block makes it be moved to block, and the upper translating rack on limited block pushes pinion rotation, pinion gear to act on lower flat
Rack is moved, lower translating rack translates up the opposite direction movement of rack, and lower translating rack pushes cowl flap rotation, by ventilation opening
It opens, to further increase the circulation of power shell inner air and outer air.In addition, moving block can opposed power inner walls rotation, lead to
Moving block angle can be positioned by crossing positioning pin so that the angle of inclination of skewed slot can be adjusted, to change from moving frame
Horizontal displacement distance, the final full swing angle for changing cooling fin.When arranged in power shell more battery unit or
When the arrangement of battery unit is more intensive, the angle of inclination of skewed slot can be properly increased, to increase the rotational angle of cooling fin, is carried
The air quantity of high cooling fin, to adapt to the radiating requirements of use environment.
