Abstract
The invention relates to a power lithium ion battery pack which comprises a plurality of single batteries arranged together, wherein all the batteries are provided with pole columns; connecting pieces are electrically connected among the pole columns; the pole columns are provided with lower buckling teeth; the lower buckling teeth comprise lower clamping bars mutually arranged in parallel; gaps among the lower clamping bars are lower grooves provided with upward openings; a plurality of upper buckling teeth are connected onto the connecting pieces and comprise upper clamping bars mutually arranged in parallel; gaps among the upper clamping bars are upper grooves provided with downward openings; the upper clamping bars are buckled in the lower grooves; the lower clamping bars are buckled in the upper grooves; and the number of the upper clamping bars is one greater/less than that of the buckling teeth. According to the novel combined structure of the power lithium ion battery pack, after the single batteries are assembled into the battery pack, the connecting pieces are directly inserted into the positive pole columns and the negative pole columns of the batteries; the upper buckling teeth which protrude downwards are arranged below the connecting pieces; the lower buckling teeth which protrude upwards are arranged on the pole columns; the upper buckling teeth are buckled with the lower buckling teeth together; the upper clamping bars are clamped into the lower grooves; the lower lamping bars are clamped into the upper grooves.
Description
Technical field
The present invention relates to a kind of battery pack, relate in particular to a kind of dynamical lithium-ion battery packs.
Background technology
At present, the mode of producing dynamical lithium-ion battery packs is, the mode that connects by welding or screw directly links to each other the positive and negative terminals of battery with brace, the connected mode complexity, and production efficiency is lower, and production cost is high.Welding performance to material also has requirement, and weld sealing-off easily occurs or erodes the defect such as weldering, can pitch after the screw rod connect hours is long, and structural instability affects internal resistance and the serviceability requirement of battery.
Summary of the invention
The purpose of this invention is to provide the dynamical lithium-ion battery packs that a kind of production cost is low, production efficiency is high.
For achieving the above object, the technical solution used in the present invention is:
A kind of dynamical lithium-ion battery packs, comprise a plurality of single batteries arranged together, on each battery with pole, be electrically connected with brace between the pole, it is characterized in that: described pole is with lower buckle teeth, lower buckle teeth comprises the lower card article of setting parallel to each other, and the space between the lower card article is low groove, the low groove opening upwards; Described brace is connected with a plurality of upper buckle teeth, and upper buckle teeth comprises the upper card article of setting parallel to each other, and the space between the upper card article is upper groove, and Open Side Down for upper groove; Upper card article snaps onto in the low groove, and lower card article snaps onto in the upper groove.
According to described dynamical lithium-ion battery packs, it is characterized in that: the radical of described upper card article and described buckle teeth differs one.
According to described dynamical lithium-ion battery packs, it is characterized in that: described upper buckle teeth comprises three upper card articles, and described lower buckle teeth comprises two lower card articles.
The present invention is the combination new construction of power lithium-ion battery, after single battery is assembled into battery pack, brace is directly snapped on the positive and negative terminals of battery, below the brace with the upper buckle teeth to lower process, on the pole with the lower buckle teeth to upper process, upper buckle teeth and lower buckle teeth snap together, upper card article snaps in the low groove, lower card article snaps in the upper groove, the battery pack that connects has in this way changed the conventional batteries bond pads or has adopted screw, the mode that nut connects, simple in structure, connection is quick, greatly reduces production cost, carried high efficiency.The brace difficult drop-off has the function of self-locking, and circuit connects contact-making surface and increases, and the internal resistance of cell reduces, and is fit to mass industrialized production.

Embodiment
The invention will be further described below in conjunction with the drawings and specific embodiments:
A kind of dynamical lithium-ion battery packs, as shown in Figures 1 to 4, comprise a plurality of single batteries arranged together 1, on each battery 1 with pole 2, be electrically connected with brace 3 between the pole 2, described pole 2 is with lower buckle teeth 5, and lower buckle teeth 5 comprises the lower card article 9 of setting parallel to each other, space between the lower card article 9 is low groove 8, low groove 8 opening upwards; Described brace 3 is connected with a plurality of upper buckle teeth 4, and upper buckle teeth 4 comprises the upper card article 6 of setting parallel to each other, and the space between the upper card article 6 is upper groove 7, and Open Side Down for upper groove 7; Upper card article 6 snaps onto in the low groove 8, and lower card article 9 snaps onto in the upper groove 7.Described upper card article 6 differs one with the radical of described buckle teeth 5, and in the present embodiment, described upper buckle teeth 4 comprises three upper card articles 6, and described lower buckle teeth 5 comprises two lower card articles 9.
When production is of the present invention, get final product in the battery electrode column of only brace need being beated in, connect very simple, and can keep connection status after connecting always, guarantee that circuit connects normal stable, the contact area of brace and pole is large, can guarantee that circuit is in low internal resistance state always.
The present invention is simple in structure, it is durable to stablize, and production capacity is strong, and raw material is easy to processing, efficiently solves battery pack connected mode complexity on the market, structural instability, connection easily comes off, cost of manufacture is high, production efficiency is low shortcoming.
