The utility model has advantages of reasonable structure, good heat radiating effect of the battery and convenient operation. And the battery box also can be placed with three 12V, 12AH batteries and six 6V, 12 AH batteries, with convenient usage.

Description

The battery case of Electrical Bicycle

Technical field

The utility model relates to a kind of battery case that rechargeable battery is housed, and especially relates to a kind of battery case of Electrical Bicycle.

Background technology

Electric bike is generally accepted by people as a kind of walking-replacing tool.Wherein a kind of Electrical Bicycle of structure is the rear profile tube place that battery case is placed on the front cross rail of cycle frame or is placed on vehicle frame, battery case is an inclined type, its complex structure, and battery case taken before and after limited space between the vehicle frame, it is not too convenient to make the rider feel to get on and off.The oblique battery box is higher because of the installation site, and car load center of gravity height makes the riding stability variation of bicycle.For reducing the center-of-gravity position of bicycle, the Electrical Bicycle that also has a kind of structure is the bottom that battery pack is placed on the vehicle frame pedal, though solved the center-of-gravity position of vehicle, but it is little to exist the ground Clearance, generation is damaged or is drawn together the battery case problem of hindering lower vehicle, because the battery installation site is too low, when loading and unloading battery, need bend over inconvenient operation simultaneously.At present, also has a kind of structure that battery is placed on vehicle seat saddle bottom, battery is placed in the battery case, lid then is hinged on the cover panel of vehicle frame both sides, though can directly charge with car, but in the time of need taking out charging to battery, then need open lid, could take out battery after again each electric connector being pulled up; After charging finishes, when refilling in battery case again, connect each electric connector again, so operation inconvenience to battery.

Summary of the invention

The purpose of this utility model provides a kind of battery case of rational in infrastructure, easy to operate Electrical Bicycle.

The utility model is that the technical scheme that achieves the above object is: a kind of battery case of Electrical Bicycle, it is characterized in that: comprise battery box that places the saddle bottom and the lid that is connected battery box top, vertical both sides of its cavity of battery box have horizontal wing plate, the top of the forward and backward baffle plate of cavity convex has the Connection Block of one, is connected with the pressing plate that joins with battery on the Connection Block; The rear end of described lid has the handle of one, and has the line hole on the lid rear quarter panel, and lid top is connected with electrical connector, and lid is connected with battery box by fastener.

The utility model beneficial effect compared with the prior art: battery case of the present utility model is directly to be placed in the vehicle frame, battery is fixed by the horizontal wing plate of its battery box cavity both sides and the pressing plate on top, not only the wing plate can carry out cross spacing to battery, and improved the intensity of battery case again, and the front and rear baffle of cavity convex carries out longitudinal register to battery, because of battery and battery tank wall area of contact little, and battery three masks have certain space, help distributing of battery heat, it is rational in infrastructure.Secondly, battery case of the present utility model is made up of battery box and the lid that is contained on the battery box, can directly be placed in the cavity of vehicle seat saddle bottom, not only realize onboard battery being charged, and can directly in the cavity of seat cushion bottom, take out the back charging to battery box and lid, need not again other electric connector to be pulled up, easy to operate.Moreover, can further improve heat dispersion by the battery separator between the battery, and can also regulate the battery of placing different voltages by battery separator.

The specific embodiment

See the battery case of the Electrical Bicycle shown in Fig. 1～4, comprise the battery box 3 and the lid 1 that place the saddle bottom, battery box 3 cavitys and vertical both sides have horizontal wing plate 3-2, laterally the height of wing plate 3-2 is at the height more than or equal to battery box 3 cavitys, for ease of placing battery, this horizontal wing plate 3-2 top has chamfering, and laterally wing plate 3-2 carries out spacing to battery 6, make the left and right sides of battery have certain space and dispel the heat, and strengthened the intensity of battery box 3 again.The Connection Block 3-3 that the top of the forward and backward baffle plate 3-4 of battery box 3 cavity convexes also has one, forward and backward baffle plate 3-4 carries out longitudinal spacing to battery 6, and the both sides of battery 6 also have the space and dispel the heat, this Connection Block 3-3 is concordant substantially with battery box 3 peripheries, has threaded insert on the Connection Block 3-3, pressing plate 4 two ends on the Connection Block 3-3 of battery box 3, are carried out battery 6 spacing, rational in infrastructure by bolted connection.Front portion at battery box 3 also has groove 3-1, and the projection on this groove 3-1 and the vehicle frame matches, and is spacing to battery case.Lid of the present utility model 1 its top vertically is the shape of a saddle, its rear end has the handle 1-1 of one, the line hole 1-3 of tool on the rear quarter panel of lid 1, be provided with in the lid 1 and battery box 3 bonded assembly cylinder 1-2, also has threaded insert in this cylinder 1-2, by fastener battery box 3 and lid 1 are connected into integral structure, also be connected with electrical connector 2 on the lid 1.

Be further to improve the heat dispersion of battery 6, see shown in Figure 3ly, battery box 3 in, also be provided with battery separator 5 between the adjacent cell 6, and the one side of battery separator 5 has uniform projection, place 3 in the battery box 3 and save 12V, 12 battery.

As not adding battery dividing plate 5, then place the battery of 6 joint 6V, 12AH in the battery box 3, combination. easy to use.
