Abstract
The utility mode discloses a lithium battery pack fender encapsulation structure. The lithium battery pack fender encapsulation structure comprises a fender, and is characterized by comprising a shell with an opening end, wherein the fender is arranged in the shell, encapsulation filler is filled between the shell and the fender, and the opening end of the shell is provided with a plugging terminal and a lead correspondingly connected with the fender. The encapsulation structure is provided with the shell, the fender is arranged in the shell and encapsulated by the encapsulation filler, and a circuit assembly structure on the fender is fixed by encapsulation so as to be isolated from the external and be well protected; moisture corrosion is avoided, and the ordinary collision and vibration in transportation cannot make the assembly loosen and separate; water-proof, vibration-proof and corrosion-proof effects are realized; and therefore, the encapsulation structure disclosed by the utility model is easy to transport and store, unlikely to lose efficacy, long in service life, stable and reliable.
Description
Technical field
The utility model relates to a kind of lithium battery group, particularly a kind of lithium battery group baffle embedding structure for power supplies such as electric tool, battery-operated motor cycle or electric bicycles.
Background technology
Lithium battery group baffle is a kind of being linked on the lithium battery group, for detection of each monomer in the battery pack charging, in the discharge process various abnormal conditions and implement the device of corresponding protection, constituted by circuit board and the various circuit units on it.Therefore has only the operate as normal of baffle to effectively guaranteeing the normal safe work of lithium battery group.And also there is following defective in present baffle structure.
1, the circuit board long term exposure of baffle runs into moisture or malaria and is easy to cause lost efficacy in air.2, baffle at sea transport or under the higher environment of coastal area salinity long storage time, circuit board can cause losing efficacy because of salt air corrosion.3, baffle all fits together with lithium battery, and the electrolyte in the lithium battery group has very strong corrosivity, when electrolyte leakage to baffle, can cause baffle to lose efficacy.4, the baffle long-term work on electric motor car or motorcycle is in vibration environment, and long vibration can make the electronic component on the baffle become flexible even come off, thereby causes baffle to lose efficacy.
In sum, there is poor stability in existing lithium battery group baffle structure, is difficult for transportation and preserves problems such as easy inefficacy.
In order to overcome the above problems, this patent has proposed a kind of baffle to be packed in the corrosion resistant shell, the structure of getting up by the embedding of insulation filling material.Allow the complete outer air of electronic component of baffle isolate, have waterproof, vibration proof, etch-proof function.
The utility model content
At the problems referred to above and deficiency, technical problem to be solved in the utility model is: how to provide a kind of simple in structure, fail safe is good, is easy to transportation and preserves the lithium battery group baffle embedding structure that is not easy to lose efficacy.Have reliable and stable characteristics.
In order to address the above problem, the utility model has adopted following technical scheme.
A kind of lithium battery group baffle embedding structure; comprise baffle; it is characterized in that; comprise that also one has the shell of openend; described baffle places in the shell; be filled with the embedding inserts between shell and the baffle, described shell aperture end place is provided with correspondence and is connected plug terminal and lead-in wire on the baffle.
In the utility model, be provided with shell, place baffle in the shell and adopt the embedding of embedding inserts.Make the circuit component configurations on the baffle be fixed by embedding, thereby be isolated from the outside, obtain excellent protection; Not only can avoid the moisture corrosion, and common collision and vibration can not cause the loosening disengaging of assembly yet in the transportation.Can realize effects such as waterproof, vibration proof, anticorrosion well.Make it be easy to transportation and preservation, be not easy to lose efficacy longer service life and reliable and stable.
As optimization, the end away from openend in the described shell is provided with base plate, and described baffle one end is fixed on the base plate.Like this, earlier baffle is fixed on the base plate, can be separated by the embedding inserts between assembly on the baffle and the shell so that guarantee during embedding.Guarantee the protection effect.
As optimization, described embedding inserts is epoxy resin or polyurethane.It is cheap to have cost, the advantage of good damping effect.Also can adopt other inserts when implementing certainly.
In sum, the utlity model has simple in structurely, fail safe is good, is not easy to lose efficacy and reliable and stable advantage, is easy to transportation and preserves longer service life.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described further.
During concrete enforcement; as shown in Figure 1; a kind of lithium battery group baffle embedding structure; comprise baffle 3; comprise that also one has the shell 2 of openend; described baffle 3 places in the shell 2, has been filled with embedding inserts 4 between shell 2 and the baffle 3, and described shell 2 open end are provided with correspondence and are connected the plug terminal 5 on the baffle 3 and go between 6.End away from openend in the described shell 2 is provided with base plate 1, and described baffle 3 one ends are fixed on the base plate 1.Described embedding inserts 4 is epoxy resin or polyurethane.
Above-mentioned embodiment; only being considered as explanation rather than restriction to the utility model preferred structure, can also be other technical schemes that are equal to when specifically implementing, such as described embedding inserts; also can also adopt other materials to obtain, should be considered as still falling into the utility model protection range.
Claims (3)
1. lithium battery group baffle embedding structure; comprise baffle; it is characterized in that; comprise that also one has the shell of openend; described baffle places in the shell; be filled with the embedding inserts between shell and the baffle, described shell aperture end place is provided with correspondence and is connected plug terminal and lead-in wire on the baffle.
2. lithium battery group baffle embedding structure as claimed in claim 1 is characterized in that, the end away from openend in the described shell is provided with base plate, and described baffle one end is fixed on the base plate.
