Specific embodiment

The utility model is more fully retouched below with reference to relevant drawings for the ease of understanding the utility model, It states.One or more embodiments of the utility model are illustratively given in attached drawing, so that disclosed in the utility model The understanding of technical solution is more accurate, thorough.However, it should be understood that the utility model can be with many different forms To realize, however it is not limited to embodiments described below.

Fig. 1 and Fig. 2 show a specific embodiment of the utility model battery structure, and the battery structure includes shell 10, battery core 20, protection board 30 and the bracket 40 being contained in shell 10.

The shell 10 is plastic shell, and whole is in hollow square box shape, including bottom case 12 and is sealedly attached to bottom case Upper cover 14 on 12.The bottom case 12 includes rectangular bottom plate 16 and the side plate 18 extended vertically upwards by 16 surrounding of bottom plate, The upper cover 14 is sealedly attached to the top of side plate 18, and bottom case 12 is closed.Perforation is formed on the bottom plate 16 of the bottom case 12 161, for the injection molding packaging after battery structure assembling；The wherein side plate 18 (side plate that diagram direction is front end) of bottom case 12 On be formed with several through-holes 181 and connect for the electrode of battery structure to be arranged with external electrical device.The battery core 20 it is whole External shape is similar to shell 10, and size is then slightly less than shell 10, can directly be loaded into shell 10.

Please refer to Fig. 3 and Fig. 4, the protection board 30 is set between battery core 20 and shell 10, is particularly located at outer Shell 10 is formed between the end face corresponding with battery core 20 of front side board 18 of through-hole 181.The protection board 30 is in lamellar knot Structure, side thereafter, i.e., towards two conducting blocks 32, such as nickel block are formed on the one side of battery core 20, two conducting block 32 divides From setting, it is electrically connected respectively with the positive and negative electrode of battery core 20.The leading flank of the protection board 30, the i.e. side plate towards shell 10 Be formed with the conductive contact 34 of several evaginations on 18 one side, the quantity of the contact 34, size, shape with side plate 18 On through-hole 181 match, each contact 34 accommodates in one-to-one through-hole 181 after assembling, as entire battery structure Electrode.

The bracket 40 is formed by integrated through injection molding, is set between battery core 20 and protection board 30, i.e., provides protection board 30 Support, while also separating battery core 20 and protection board 30, play insulating effect.As shown in Figures 2 and 4, the bracket 40 is whole In lamellar, including ontology 42 and ribs 44 made of being protruded as ontology 42 towards protection board 30.The ontology 42 is length Square plate, the back side are plane, can with the end face of battery core 20 is good fits.The ribs 44 from before ontology 42 to It extends vertically, is mutually supported with the trailing flank of protection board 30 outside, support positioning is provided.Preferably, the 44 face contact of ribs 34 positions give contact 34 enough support forces, and contact 34 is avoided to sink.In the present embodiment, the ribs 44 are multiple points Rib from setting, in other embodiments, the quantity of ribs 44, which can according to need, to be adjusted, and it is enough to guarantee that offer is done Support force.

When producing the utility model battery structure, battery core 20, protection board 30 and bracket 40 are placed in shell 10 In bottom case 12, it is aligned the contact 34 of protection board 30 one by one with the through-hole 181 on bottom case 12, and by the electrode of battery core 20 and protection 32 spot welding of conducting block of plate 30 is connected, and upper cover 14 is welded in the shell 10 that sealing is formed on bottom case 12 later；Finally by wearing Hole 161 is molded into shell 10, by protection board 30, battery core 20,10 encapsulated moulding of shell.During injection molding packaging, protection It is provided with bracket 40 between plate 30 and battery core 20, support is provided, and bracket 40 is the integral structure of injection molding, dimensionally There can be quite high precision, effectively avoid auxiliary material tolerance issues, provide enough supports to protection board 30 and position, guarantee protection Contact 34 on plate 30 is not sunk, and the battery structure so produced, which has, to be had excellent performance.In addition, since bracket 40 is integrated knot Structure, it is more simple, conveniently in fit on relative to pasting two layers of auxiliary material, it can largely promote battery structure Production efficiency.

It should be noted that the utility model is not limited to above embodiment, creation essence according to the present utility model Mind, those skilled in the art can also make other variations, these variations done according to the creative spirit of the utility model, all Should be included in the utility model it is claimed within the scope of.
