Detailed description of the invention
Referring to accompanying drawing, embodiments of the present invention is described in detail.Fig. 1 is the schematic top plan view of an electronlmobil of the present invention embodiment, Fig. 2 is the front view of Fig. 1, please refer to Fig. 1 Fig. 2, the electronlmobil that the embodiment of the present invention provides comprises car body 2 and power brick 1, car body 2 side opening is provided with battery installing port 201, and battery installing port 201 extends to form battery flat 203 in car body 2; Power brick 1 comprises housing and is placed in the battery of enclosure interior, and housing is placed in battery flat 203, and housing is fixedly mounted in battery flat 203 by snap-in structure.
Particularly, car chassis can arrange car body, in car body, form the cavity being used for accommodating passenger.Can on front side of car body 2, rear side or both side surface offer a battery installing port 201, can be provided with the battery flat 203 extended by battery installing port 201 in car body inwardly, battery flat 203 surrounds the accommodation space mated with power brick 1.Further, on the housing of power brick 1 and battery compartment wall corresponding can be arranged the snap-in structure of coupling, to be fixed in battery flat 203 by snap-in structure by power brick, also utilize battery installing port 201 pairs of power brick advance and extract out simultaneously.
The electronlmobil that the present embodiment provides is when changing, more exchange device for changing power brick being arranged on ground, directly can extracting galvanic battery bag out from side body, and then new power brick is inserted in battery flat easily by side body, just can complete replacing, operate very simple and convenient.Not only greatly can simplify and change electric equipment, and when breaking down, only just can need realize manually changing power brick easily by means of simple device.
Fig. 3 is partial schematic sectional view and the schematic top plan view of another embodiment of electronlmobil of the present invention, Fig. 4 is the schematic top plan view of Fig. 3, refers to shown in Fig. 3, Fig. 4, optionally, housing is fixed with male part 107, and it is peripheral that male part 107 extends to battery installing port 201.Housing can also comprise a housing body 108, is fixedly connected with male part 107, and male part 107 is arranged on housing body 108 one end.
In addition, the cross sectional dimensions of battery installing port 201, should be slightly larger than the cross sectional dimensions of the housing body 108 of power brick 1, to facilitate the taking-up of power brick 1 and to push.Such as, when power brick shape is rectangular-shaped, the length of battery installing port 201 and width are greater than length and the width of housing body 108, and the length of battery flat 203 and width are greater than length and the width of battery container main body 108; The growing and be wider than the length of battery installing port 201 and wide of male part 107.
Preferred in the present embodiment, optionally, when power brick is rectangular block shape, power brick can have following size: width is about 0.5m, and length is about 1m, is highly about 0.2m, and its volume is about 100L.The power brick of above-mentioned size can be placed in small passenger car.It should be noted that, the concrete size of the power brick provided in the present embodiment, refers to the size of power brick housing body 108, and is above-mentionedly of a size of preferred dimensions, be not changeless, concrete size can according to concrete structure space and the amendment accordingly of the functional requirement place of making.
In the present embodiment, optionally, battery can all be arranged in power brick housing body 108, do not need to split into baby battery module, for battery management and heat management create good condition, also the electrical connection between power brick 1 and electronlmobil is made to only have two high-voltage DC power supply lines, CAN communication line and control signal wire, greatly simplify the type of attachment between power brick 1 and vehicle, can carry out easily connecting and disconnecting, simplify the electrical connection between power brick and vehicle, be easy to the quick-replaceable guaranteeing safe and reliable connection and power brick between the two.
In this example, when changing power brick 1, can being directly stuck in male part 107 by changing electric equipment, easily power brick 1 being extracted out, manual operation and person works's amount can be reduced.Wherein, male part 107 protrudes from car body surface, can be designed to for the battery-driven car of different model the width that male part 107 outermost surface is no more than back mirror in electronlmobil, not affect width over sides of car body parameter, also avoid affecting and pass through performance when vehicle travels.
Male part 107 with the position relationship of car body can be, male part 107 can be arranged on side wheel cover trailing edge near the side of headstock, male part 107 can be arranged on the other B post lower end of electric car cab near the side of the tailstock, B post is between the front stall and back seat of car body, car bottom is extended to from roof, because B post plays the supporting role to car body, during side collision, impact or energy are held and can be transmitted to side wheel cover trailing edge and B post lower end by male part 107, thus the impact force reduced power brick, the peripheral structure reducing power brick 1 is out of shape the cell damage caused.
It should be noted that, male part 107 can in the oblong platy structure corresponding with housing cross-sectional, and the outside face of male part 107 then can carry out according to car body curved surface and aerodynamics the globoidal structure that designs; And the deflection etc. that the thickness of male part 107 may be able to cause according to side collision is determined, make impact or energy transferring to be gone out when colliding, design parameter is in this no limit.
Optionally, the anti-striker 701 that a rigidity is greater than housing is also provided with in the male part 107 that the present embodiment provides.Wherein, anti-striker 701 can be greater than the body of rod or the steel plate of external component material for rigidity.
When anti-striker 701 steel plate, male part 107 can be arranged at inner and can perpendicular to power brick.When anti-striker 701 is one or more lever, male part 107 can be arranged at inner, male part 107 surface can be parallel to, and can arrange perpendicular to power brick.When colliding, steel plate or lever are used for keeping out impact force, prevent the distortion of power brick, thus protect power brick.
In an embodiment of the present invention, crash sensor 702 can also be provided with in male part 107, crash sensor 702 is electrically connected with entire car controller, for gathering deceleration/decel signal and exporting to described entire car controller, to make entire car controller when deceleration/decel signal is more than or equal to predetermined threshold value, control battery runs down.
Crash sensor 702 can be arranged on male part 107 towards car body side, also can be arranged in male part 107.Once collide, the deceleration/decel signal that crash sensor 702 can detect collision and produce, and flow to entire car controller in real time, this deceleration/decel signal value and predetermined threshold value compare by entire car controller, when this deceleration/decel of discovery reaches predetermined threshold value, namely control power brick 1 power-off, cut off the power supply of power brick when colliding and occurring in time, avoid battery in power brick be short-circuited after an impact and then cause blast, ensure that the electric safety of vehicle.
The present embodiment is by arranging crash sensor; realize when colliding; battery component more in available protecting power brick; save collision rift power brick deform or damage thus need to change the cost of power brick; and after collision occurs, cut off the power supply of power brick in time; avoid battery in power brick be short-circuited after an impact and then cause blast, ensure that the electric safety of electronlmobil.
