In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation Example, the present invention will be further described in detail.It should be appreciated that specific embodiment described herein is only used to explain The utility model is not used to limit the utility model.

The realization of the utility model is described in detail below in conjunction with specific embodiment.

The same or similar label correspond to the same or similar components in the attached drawing of the present embodiment；In retouching for the utility model In stating, it is to be understood that if the orientation or positional relationship for having the instructions such as term " on ", "lower", "left", "right" is based on attached drawing Shown in orientation or positional relationship, be merely for convenience of describing the present invention and simplifying the description, rather than indication or suggestion institute The device or element of finger must have a particular orientation, be constructed and operated in a specific orientation, therefore position pass is described in attached drawing The term of system only for illustration, should not be understood as the limitation to this patent, for those of ordinary skill in the art and Speech, can understand the concrete meaning of above-mentioned term as the case may be.

It is preferred embodiment provided by the utility model shown in referring to Figures 1 and 2.

The utility model provides a kind of battery protecting plate structure convenient for emergency starting, for being protected to battery, The overshoot or over-discharge of battery are avoided, also, after protection board 11 works internal break, the second pole block 122 and first can be passed through The emergency starting of battery is realized in electrically conducting for pole block 121.

Battery protecting plate structure provided in this embodiment convenient for emergency starting, including over-discharge is carried out to battery or overcharges guarantor The protection board 11 of shield, protection board 11 have the first connecting line 111 connecting with battery pack and the second connection with load connection Line 112 is convexly equipped with the first pole block 121 and the second pole block 122,111 electricity of the first pole block 121 and the first connecting line on protection board 11 Property conducting, the second pole block 122 electrically conducts with the second connecting line 112；First pole block 121 and the second pole block 122 electrically conduct or It disconnects.

In this way, protection board 11 is connected among circuit, when battery occurs overshooting or when over-discharge phenomenon, protection board 11 is disconnected Road is protected with realizing to battery, avoids cell damage, also, after protection board 11 works, internal break can be by protection board It electrically conducts between the first pole block 121 and the second pole block 122 of 11 protrusions, makes to form short circuit inside protection board 11, and then make electricity Pond group is directly electrically connected with load, and secondary emergency starting can be carried out to battery pack.

In the present embodiment, the first pole block 121 and the second pole block 122 are located at the same end face of protection board 11, in this way, needing When by 122 short circuit of the first pole block 121 and the second pole block, it is easier to make the first pole block 121 and second by conducting wire or other modes Pole block 122 is electrically connected, and structure is simple, easy to operate.

Specifically, the method for being electrically connected the first pole block 121 and the second pole block 122 that the utility model provides, be First pole block 121 is hinged with conductive sheet 13 away from the outer end of protection board 11, and conductive sheet 13 be rocked to abut the second pole block 122 or It is rocked to far from the second pole block 122, in this way, need to only be stirred conductive sheet 13 when needing emergency starting battery pack, make its swing To the second pole block 122 is abutted, the first pole block 121 of realization electrically conducts with the second pole block 122, easy to operate quick.

In above structure, conductive sheet 13 can also be arranged on the second pole, be swung relative to the second pole, this implementation First pole and the expression merely for convenience of the second pole described in example.

Also, conductive sheet 13 is provided with conductive notch 131 towards 122 side of the second pole block, and when conductive sheet 13 is rocked to abutting After second pole block 122, the second pole block 122 is embedded in conductive notch 131, in this way, more stable, the first pole that conductive sheet 13 abuts Electrically conducting between block 121 and the second pole block 122 is also more stable.

In this way, position limiting structure is additionally provided on protection board 11 in order to avoid conductive sheet 13 is arbitrarily swung, when conductive sheet 13 is put When moving to the position of position limiting structure, conductive sheet 13 is fixed, avoids it from arbitrarily swinging and influences the normal working condition of protection board 11.

Specifically, above-mentioned position limiting structure is limited post 14 of the projection on protection board 11, limited post 14 is equipped with and is fixed with Stop screw 141, and it has then been correspondingly formed limit hole on protection board 11, when protection board 11 works normally, conductive sheet 13 is put It moves to the position for being placed in limited post 14, and limit hole is passed through by the stop screw 141 on limited post 14 and is fixed on limited post 14 On, to realize the fixation of conductive sheet 13, when needing emergency starting, screw is removed, structure is simple, convenient for production.

Certainly, can also projection is flexibly connected with limited post 14 on limited post 14 telescopic mast, telescopic mast is along limited post 14 Extending direction move up and down, and be intended in elongation state, i.e., under normal condition, telescopic mast passes through the limit of conductive sheet 13 In hole, realizes and fix, when needing emergency starting, press telescopic mast, make its shortening, so as to be put to conductive sheet 13 It is dynamic.

And in order to keep conductive sheet 13 more stable when abutting the second pole, in the present embodiment, conductive sheet 13 can be arranged The second pole is abutted to be intended to be rocked to, i.e., is connected between conductive sheet 13 and the first pole by torsional spring, in this way unless will lead Electric piece 13 is fixed, after unclamping conductive sheet 13, can directly be rocked to and abut the second pole, keep conductive sheet 13 and the second pole steady Fixed connection.

In the present embodiment, in the form of sheets, and conductive sheet 13 is along the Plane Rotation for being parallel to protection board 11 for conductive sheet 13, in this way The occupied space of screening glass is reduced, is easy to use.

And in other embodiments, conductive sheet 13 is then to be rocked to the end that be located in the second pole block 122, makes the second pole block 122 end is embedded in notch, or is rocked to the extending direction of the first pole block 121, and the screening glass being arranged in this way is opened in emergency It is more stable when dynamic connection.

In addition, rubber protecting jacket 132 is arranged with outside top of the conductive sheet 13 far from the first pole block 121, in this way, artificially dialling When moving conductive piece 13, avoid getting an electric shock, use is safe.

Also, it is also enclosed with plastic cement in the periphery of the first pole and the second pole, only in conductive sheet 13 and the second pole The position of contact is open, and avoids short circuit and electric shock, use safe.

The above is only the preferred embodiments of the present utility model only, is not intended to limit the utility model, all practical at this Made any modifications, equivalent replacements, and improvements etc., should be included in the guarantor of the utility model within novel spirit and principle Within the scope of shield.
