Abstract
The utility model discloses a standby battery for an electric bicycle, aiming at providing a standby battery which is small in volume, light in self weight, convenient to carry and applicable to various electric vehicles. The standby battery comprises a box body, a battery and a socket, wherein a box cover is arranged on the box body, a lithium battery pack is arranged in the box body, and a square socket, a round socket and a changeover switch are arranged on one end panel of the box body. A lithium battery is adopted as a power supply, the standby battery has the advantages of being small in volume, light in weight and large in capacity and maintenance-free without memory, can be charged in use at any time, the square socket and the round socket arranged on the end panel can adapt to shape of the conventional plugs of the conventional electric bicycle, and the changeover switch can change anode and cathode polarity of the output voltage of the battery so as to adapt to different polarity of battery output voltage on the conventional electric bicycle.
Description
Technical field
The utility model relates to a kind of electric bicycle technology, in particular, is a kind of electric bicycle reserve battery.
Background technology
At present; The electric bicycle of selling on the market when dead battery under steam, can only be stepped on row or carry out or seek quick charge station charging nearby by manpower; But because the deadweight of electric bicycle is bigger; Step on row or carry out muscle power and the time, and quick charge also need expend time in labor, and to very big infringement is arranged in useful life of battery.A kind of disclosed on the Chinese patent document " the dual power supply method of electric bicycle and power supply mounting structure "; Its publication number is CN1754716A; This technical scheme adopts two identical power supplys of specification to be respectively main power source and stand-by power supply, all uses main power source earlier at every turn.Behind the several times that go, when main power source begins the stroke deficiency, begin to use instead stand-by power supply again, supply stroke.Along with the increase of travel times, the main power source stroke descends one by one, until using until exhausted; After main power source was scrapped, the new power supply of buying was as stand-by power supply, and stand-by power supply originally transforms main power source into; The new duplicate supply of forming still uses as stated above.Be installed in two power supplys respectively the left and right sides of bicycle rear rack.Adopt this method, can make full use of battery, avoided waste, practiced thrift 1/4-1/3 with originally comparing.Guaranteed good rideability, the both sides after being installed in battery pack below the clothes hanger make the overall structure of electric bicycle more become rationally succinct.But owing to this reserve battery is placed in the electric motor car all the time, and have the total amount identical with primary cell, increased the total amount of car load, power consumption strengthens in feasible the going, and this reserve battery can not use in the different electric motor car of other battery plug.
The utility model content
The utility model is devoted to solve in the prior art because electric motor car when storage battery does not have electricity under steam, can only be stepped on row or carry out or seek the defective of quick charge station charging nearby.Aim to provide a kind of volume little, from heavy and light, easy to carry, be applicable to the reserve battery that multiple electric motor car uses.
In order to solve the technical problem of above-mentioned existence; The utility model adopts following technical proposals: a kind of electric bicycle reserve battery; Comprise box body, battery and socket; Described box body top is provided with lid, is provided with the lithium battery group in the box body, and end plates of described box body are provided with side socket, round socket and change over switch.Volume is little, in light weight, capacity reaches the memoryless property of battery and non-maintaining greatly because the employing lithium battery as power source, has
,Can be with using with filling; The side socket, the round socket that are arranged on the end plates can adapt to existing plug shape on the existing electric bicycle, and the positive-negative polarity that change over switch can change cell output voltage adapts to the opposed polarity that has cell output voltage on the electric bicycle now.
As preferably; The lithium battery group by several lithium batteries serial connection or and connect and form; Lithium battery group top is provided with protection module; Like this can be easily the lithium battery group be assembled into different electric bicycle required voltages and various capacity adapting to various demands, protection module can be when electric bicycle goes and protection battery when battery discharge or charging.
As preferably; Side socket, round socket are connected with change over switch through lead; Change over switch is connected with protection module through lead; Protection module is connected with the lithium battery group through lead; Side socket that is provided with simultaneously and round socket can exchange the both positive and negative polarity of side socket and round socket through change over switch, can adapt to the power interface of thumping majority electric bicycle and the positive-negative polarity of power supply like this, through protection module can effectively reach the overcharging of lithium battery group, mistake is put, overcurrent, charging balance and temperature protection.
As preferably, the change over switch left side or the right are provided with indicator light, can indicate the whether reversal connection of electric power polarity of side socket and round socket; When electric power polarity is correct; Indicator light shows green, when the electric power polarity mistake, and the indicator light exhibit red; At this moment must pull change over switch and come conversion electric power polarity, make that indicator light is shown in green can be used.
As preferably; Box body two sides side plate upper inner is provided with chute, and the dual-side of lid is provided with the step limit with the chute establishing, can pull out or plug lid easily like this; Make things convenient for the installation or the maintenance of part in the box, can certainly adopt the method for hinge to open lid.
Because adopt technique scheme, the beneficial effect of a kind of battery of electric bicycle provided by the invention is: 1. volume little, from heavy and light; 2. easy to carry; 3. be applicable to that multiple electric motor car uses.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described in detail:
Embodiment 1
In the embodiment shown in the accompanying drawing 11, described box body 1 top is provided with lid 8, is provided with lithium battery group 2 in the box body 1; End plates of described box body 1 are provided with side socket 5, round socket 6 and change over switch 7; Lithium battery group 2 is connected in series by several lithium batteries or goes here and there and connect and form, and lithium battery group 2 tops are provided with protection module 4, and side socket 5, round socket 6 are connected with change over switch 7 through lead; Change over switch 7 is connected with protection module 4 through lead; Protection module 4 is connected with lithium battery group 2 through lead, and box body 1 two sides side plate upper inner is provided with chute 3, and the dual-side of lid 8 is provided with the step limit (9) with chute 3 establishings.
The utility model is placed on reserve battery on the electric bicycle in use, extracts on the electric bicycle and primary cell wire connecting plug; Then this wire and plug is inserted side socket 5 or round socket 6; If the red colored lamp of indicator light 10 is bright, then indicate electric power polarity opposite, at this moment should be with change over switch 7 dislocations; Make the both positive and negative polarity and the both positive and negative polarity on the electric bicycle of reserve battery adaptive; The bright back of the green light of indicator light 10 just can have been used, when use remove reserve battery after, deposit after to the reserve battery full charge subsequent use with adaptive lithium battery charger.
