The concrete meaning of above-mentioned term is understood as the case may be.
It is preferred embodiment provided by the invention with reference to shown in Fig. 1~4.
The Joining Technology of lamina tecti and housing provided by the invention, for solve lamina tecti by welding with housing
When being fixedly connected, the formed welding bead of welding is raised upward, the problem of causing lithium battery inconvenient for use, also available for other types
Battery in, be not limited only to the present embodiment.
The Joining Technology of lamina tecti and housing is formed with the company around 11 periphery of lamina tecti arrangement in the periphery of lamina tecti 11
Connect ring；The encirclement of housing 12 is formed with inner cavity, and inner cavity has the accent through 12 top of housing, can be by battery core etc. by accent
Inner part is put into cavity；Upwardly disposed top end surface is formed at the top of the side wall of housing 12, top end surface includes welding
Portion and the abutting part with weld part integrally connected, abutting part arrange that weld part is around the outer of abutting part around the periphery of accent
It arranges in week, the size shape of abutting part is identical with connecting portion；
After lamina tecti 11 is enclosed on the accent of housing 12, the bottom of connection ring is connected on abutting part, connection ring
The welding groove 13 for being looped around 11 periphery of lamina tecti is formed between outer peripheral sidewall and weld part, the vertical welding shape on welding groove 13
Into welding bead, lamina tecti 11 is fixedly connected with housing 12 by welding bead.
The lamina tecti of above-mentioned offer and the Joining Technology of housing, by forming connection ring in the periphery of lamina tecti 11, in shell
The top of body 12 is provided with abutting part and weld part, when lamina tecti 11 is enclosed on the accent of housing 12, the bottom of connection ring
It is connected on abutting part, the welding groove 13 of annular is formed between the outer peripheral sidewall of connection ring and weld part at this time, in welding groove 13
Upper vertical welding can realize being fixedly connected for lamina tecti 11 and housing 12.In this way, welding groove 13 provides space to welding bead, keep away
Exempt from welding bead protrusion on the surface of housing 12 or lamina tecti 11, facilitate the use of lithium battery, solve lamina tecti 11 and pass through weldering
When the mode connect is fixedly connected with housing 12, the formed welding bead of welding is raised upward, and lithium battery is caused to assemble the problem of inconvenient.
After vertical welding, the surfacing of the welding bead of welding groove 13 is not in original technique in arc-shaped
Welding bead is caused to protrude problem.
Specifically, the top of welding bead is concordant with the top of lamina tecti 11, and welding bead has on the outside of the welding bead of lamina tecti 11
Wall, the welding bead lateral wall are concordant with the lateral wall of housing 12, that is to say, that welding bead just fills up welding groove 13 so that welding bead
Top and the top of lamina tecti 11 seamlessly transit, the lateral wall smooth excessiveness of welding bead lateral wall and housing 12 so that lamina tecti
11 are connected more securely with housing 12, while also avoid forming unnecessary slot hole in the outer surface of lithium battery.
Specifically, arc-shaped transition between the top of welding bead and welding bead lateral wall, this way it is possible to avoid the top of lithium battery
Sharp edge is formed between the lateral wall of lithium battery so that the use process of lithium battery is safer.
Wherein, the rectangular shape arrangement of weld part, the top surface of weld part form the welding surface of four strips, adjacent welding
Face is end to end, and the width of welding surface is equal everywhere, so that the width of welding bead is consistent, lithium battery is avoided to generate welding thin
Weakness improves the whole mechanical strength of lithium battery.In the present embodiment, the horizontal arrangement of weld part is so that it is convenient to housing 12
Production, according to actual needs, weld part also may be configured as other modes.
In the present embodiment, the side wall of lamina tecti 11 is arranged in vertical shape, so that the side wall and weld part of lamina tecti 11
Between 13 from-inner-to-outer of welding groove that is formed in horn-like, facilitate the welding between lamina tecti 11 and housing 12；11 side of lamina tecti
The height of wall is identical everywhere, so that the thickness of the welding bead formed after welding is identical, lithium battery is avoided to generate welding weak
Point improves the whole mechanical strength of lithium battery.
In the present embodiment, the bottom of lamina tecti 11 is provided with the inlay in embedded accent, when lamina tecti 11 is enclosed in accent
When, the lateral wall of inlay is abutted with the madial wall of housing 12.It, will when needing lamina tecti 11 being enclosed on the accent of housing 12
Inlay is embedded into accent, then applies pressure down so that the bottom of connection ring is mortgaged in the mortgage portion of housing 12, at this time
Lamina tecti 11 is on predetermined position, in this way, by setting inlay, can quickly position the position of lamina tecti 11, and have
Aid in the effect of fixed roof plate 11.
In the present embodiment, the bottom surface of connection ring and the top surface of abutting part are plane, in this way, on the one hand facilitating lamina tecti
11 with the connection of housing 12, on the other hand, plane will be arranged at the top of the bottom surface of connection ring and abutting part, can so be subtracted
Few gap of the connection ring with abutting part after abutting, avoids the liquid metal in welding process from entering in cavity, influences lithium electricity
The performance in pond.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all essences in the present invention
All any modification, equivalent and improvement made within refreshing and principle etc., should all be included in the protection scope of the present invention.
