Further, also be provided with fairlead in described left shell or the right shell, be used for the baffle lead-in wire and pass, it is safe and reliable to guarantee to go between.
Described internal stent is provided with location hole, is used to place battery unit, and its quantity can be a plurality of, decide according to battery unit quantity, its arrangement mode and battery unit combination mode is consistent, location hole is set after, adjacent two battery units do not contact, and heat radiation is good when making battery charging and discharging.Further, described location hole one side is provided with catch, prevents that battery unit is at axial motion even fall.
As of the present invention preferred, described support madial wall also is provided with the depression of passing for lead-in wire, and lead-in wire is drawn by this depression, and the influence that can avoid going between because of external force damages or short circuit.
Outstanding advantage of the present invention and beneficial effect are:
1, uses the support self-contained battery, use insulation crust and support chimeric again, guaranteed the firm of support; Fixing hole double fixed in screw in the raised line of the left and right shell of insulation crust by lateral wall and the inner many spud piles 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 on try to get to the heart of a matter inwardly protruded many spud piles and the spud pile can be guaranteed the steadiness that the battery pack protection plate is radial and axial, has 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 the 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 the support of the present invention, can be according to the quantity of battery unit and arrangement mode design, this location hole makes that battery unit is firm 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 not expose outside; 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, make things convenient for battery to be installed on other parts, such as wheel hub.
Description of drawings
Fig. 1 is a type example structure exploded view of the present invention.
Fig. 2 is an embodiment of the invention supporting structure schematic diagram.
Fig. 3 a, 3b are embodiment of the invention left side shell, right shell structure schematic diagram.
Among the figure, 1 is support, and 11 is groove, and 12 is location hole, and 13 is catch, and 14 are depression, and 21 is raised line, and 22 is left shell, and 23 is right shell, and 24 is spud pile, and 25 is fairlead, and 3 is battery pack, and 4 is screw.
Embodiment
Below in conjunction with embodiment the present invention is described in further detail.
As shown in Figure 1, the 18650 type lithium battery groups 3 of using 18650 type lithium cells to form with ten and ten string modes, its lithium battery group 3 fixtures comprise the support 1 that is provided with centre bore, be located at the support 1 outer plate-like insulation crust that is provided with centre bore equally, insulation crust is made up of left shell 22 and right shell 23, and both are fixing by screw 4.Compact overall structure, aesthetic in appearance, centre bore setting makes things convenient for battery to be installed on other parts, particularly wheel hub.
As shown in Figure 2, for being positioned at the support that is provided with centre bore 1 of battery pack 3 one sides, the support 1 of battery pack 3 both sides is and is symmetrical arranged among the figure, and structure is identical, is convenient to adopt the Mould Machining manufacturing.Support 1 adopts ten and ten strings identical with battery unit combination mode to arrange by 30 location holes 12 and forms, battery unit places location hole 12, certain distance is spaced between the battery unit in each location hole 12, so battery pack 3 thermal diffusivities are good, at least be provided with a catch 13 on the location hole 12, can prevent that battery unit is at axial motion, thereby reach the purpose of self-contained battery unit, support 1 outward flange is provided with 6 axial notches 11, in order to be provided with to projecting inward six roots of sensation raised line 21 chimeric with the insulation crust sidewall, make support 1 maintain static, support 1 madial wall also is provided with the depression 14 of passing for lead-in wire, feasible lead-in wire can not be subjected to the influence of external force, thereby has improved the fail safe of battery.
As Fig. 3 a, shown in the 3b, be respectively left shell 22 and right shell 23 among the figure, both pass the screw that is provided with in the set six roots of sensation raised line 21 of sidewall by screw and the fixing hole be located at from 4 spud piles 24 of inwardly protruding of trying to get to the heart of a matter connects.Left and right shell has all carried out fastening from inside to outside, has effectively prevented to cause because of concuss the dislocation of fixture, thereby has improved the steadiness of battery.Right shell 23 also is provided with fairlead 25, is used for the baffle lead-in wire and passes, and it is safe and reliable to guarantee to go between, and wherein spud pile 24 also is used for radially fixedly baffle, and spud pile 24 is provided with elastic washer, guarantees that further baffle is at axial steadiness.As seen not only to have played fixed support 1 be the purpose of self-contained battery group 3 to insulation crust; also have the fixedly effect of baffle, in addition, it also has insulation, water-proof function; farthest improve the stability and the fail safe of battery pack 3, thereby prolonged battery useful life.
This specific embodiment only is an explanation of the invention; it is not the restriction to invention; those skilled in the art can make any modification to present embodiment as required after reading this specification, but as long as all are subjected to the protection of Patent Law in claim scope of the present invention.
