Further, in described left shell or right shell, also be provided with fairlead, for the protection of plate lead-in wire through, guarantee to go between safe and reliable.
Described internal stent is provided with location hole, and for the placing battery unit, its quantity can be a plurality of, according to battery unit quantity, determine, its arrangement mode is consistent with battery unit combination mode, after location hole is set, adjacent two battery units do not contact, and while making battery charging and discharging, heat radiation is good.Further, described location hole one side is provided with catch, prevents that battery unit from even falling at axial motion.
As of the present invention preferably, described support madial wall also be provided with for lead-in wire through depression, lead-in wire is drawn by this depression, can avoid lead-in wire to damage or short circuit because of the impact of external force.
Outstanding advantages of the present invention and beneficial effect are:
1, use the support self-contained battery, then use insulation crust and support chimeric, guaranteed support firmly; Fixing hole in screw in the raised line of the left and right shell of insulation crust by lateral wall and inner many spud piles is dual fixing, has further improved the stability of battery pack, and insulation crust also has waterproof, insulation function and effectively protected battery pack;
2, the setting of the elastic washer of the left and right shell of insulation crust from try to get to the heart of a matter inwardly protruded many spud piles and spud pile, can guarantee the steadiness that the battery pack protection plate is radial and axial, improved its anti-vibration resistance and fail safe;
3, the support madial wall is provided with the fairlead setting in depression and left shell or right shell, can avoid lead-in wire gone between by external force, thereby improve the fail safe of battery pack;
4, be provided with location hole in support of the present invention, can be according to quantity and the arrangement mode design of battery unit, this location hole makes battery unit firmly and has improved the heat dispersion of battery pack;
5, not only self-contained battery but also fixing baffle of insulation crust of the present invention; after using insulation crust; battery can be outside not exposed; have disguise, this structural design can make battery pack, support, insulation crust become one, compact conformation; attractive in appearance; this support arm and insulation crust are equipped with centre bore, facilitate battery to be arranged on other parts, such as wheel hub.
