Description
Technical field
The utility model relates to a kind of high capacity cell module, relates in particular to a kind of being laid with array format by a plurality of cylindrical lithium batteries and the high capacity cell module forming in parallel.
Background technology
At present, as the motor for to motor vehicle, supply with the battery of electric power.Mostly the battery pack of using a plurality of battery cell set to be connected and to form, i.e. so-called battery module.And because the connected mode of battery cell comprises parallel connection, series connection or connection in series-parallel etc., so battery pack is also divided into polytype, and the utility model for be cell parallel module wherein.
Along with becoming better and approaching perfection day by day of battery cell production technology, cylindrical lithium battery has obtained application more and more, and especially this battery forms is suitable for forming cell parallel module, is convenient in batches cascade and no longer need intricately winding displacement of positive and negative electrode.But in actual applications, each battery cell and come in battery case after because vehicle jolts, be very easily shifted, collide, in serious situation, cause the problems such as sealing-off, malfunctioning or inside battery leakage.
Summary of the invention
In view of the defect that above-mentioned prior art exists, the purpose of this utility model is to propose a kind of cylindrical lithium battery parallel module, solves the problem of the firm attaching of battery cell in battery module.
The purpose of this utility model, to be achieved by the following technical programs: a kind of cylindrical lithium battery parallel module, by several cylindrical lithium battery parallel connections, formed, it is characterized in that: described parallel module comprises anodal nylon cover plate, negative pole nylon cover plate, negative pole aluminium backing, anodal nickel sheet and negative pole nickel sheet, the container that wherein said anodal nylon cover plate is cylindrical lithium battery, described anodal nickel sheet is located at anodal nylon cover plate bottom soldered with the positive pole point of cylindrical lithium battery, described negative pole aluminium backing and the one attaching of negative pole nylon cover plate and be provided with Correspondent cy linder lithium battery quantity position hole, described negative pole nickel sheet is located at negative pole nylon cover plate outside and is connected with the cathode pot-welding that is positioned the cylindrical lithium battery in negative pole aluminium backing, just, negative nylon cover plate engages.
Further, the joint of described anodal nylon cover plate and negative pole nylon cover plate is circumferentially with movable hasp more than two or buckle.
Further, described parallel module comprises two top cover plates, and two top cover plates engage with anodal nylon cover plate and negative pole nylon cover plate in two relative side direction respectively.
Remarkable result after technical solutions of the utility model application implementation is: by positive and negative nylon cover plate and negative pole aluminium backing to cylindrical lithium battery carry out effectively, machinery is fixing reliably; fire-retardant nylon shell can protect cylindrical lithium battery to contact with the hard of external component; stability while having improved the structure of cell parallel inside modules and module whole operation, and assembling product and safeguard convenient.
Accompanying drawing explanation
Fig. 1 is the overall appearance schematic diagram of the utility model cylindrical lithium battery parallel module.
Fig. 2 is the structure explosive view of the parallel module of cylindrical lithium battery shown in Fig. 1.
Embodiment
Below just accompanying drawing in conjunction with the embodiments, is described in further detail embodiment of the present utility model, so that technical solutions of the utility model are easier to understand, grasp.
The utility model researcher is for the fault of construction of the existing parallel module based on cylindrical lithium battery, concentrate on studies and proposed the metastable cylindrical lithium battery parallel module of a kind of structure, for the further application of cylindrical lithium battery provides good technical solution.
In conjunction with diagram, understand this programme, this parallel module comprises anodal nylon cover plate 1, negative pole nylon cover plate 2, negative pole aluminium backing 3, anodal nickel sheet 4 and negative pole nickel sheet 5 as depicted in figs. 1 and 2, the container that wherein anodal nylon cover plate is cylindrical lithium battery, the cylindrical lithium battery 9 that is array-like distribution is arranged one by one and is installed among anodal nylon cover plate 1.From positive pole always, anodal nickel sheet 4 is located at anodal nylon cover plate 1 bottom soldered one by one with the positive limit of cylindrical lithium battery 9, from negative pole always, negative pole aluminium backing 3 and the 2 one attachings of negative pole nylon cover plate are also provided with the hole 31, position of Correspondent cy linder lithium battery quantity, like this cylindrical lithium battery 9 just can be embedded one by one wherein located clamping.And negative pole nickel sheet 5 is located at negative pole nylon cover plate 2 outsides and connect with the cathode pot-welding that is positioned the cylindrical lithium battery 9 in negative pole aluminium backing 3, positive and negative nylon cover plate engages.Thus, the parallel connection of lithium battery positive and negative electrode is mainly welded each cylindrical lithium battery positive and negative electrode by two ends nickel sheet and is realized.
As the scheme of further refinement, this positive pole nylon cover plate 1 is circumferentially with movable hasp 7 more than two with the joint of negative pole nylon cover plate 2, is convenient to open fast nylon outer shell and safeguards the cylindrical lithium battery of changing any fault wherein or end-of-life.In addition, except above-mentioned hasp 7, other movable syndeton can also be set, as buckle etc.And parallel module can also comprise two top cover plates 61,62; and two top cover plates engage with anodal nylon cover plate 1 and negative pole nylon cover plate 2 in two relative side direction respectively; this top cover plate effectively protection module two ends contacts with the hard of external component, avoids short circuit.
To sum up the description about the utility model cylindrical lithium battery parallel module structure and assembling is appreciated that; by positive and negative nylon cover plate and negative pole aluminium backing to cylindrical lithium battery carry out effectively, machinery is fixing reliably; fire-retardant nylon shell can effectively be protected the unusual fluctuation of cylindrical lithium battery; stability while having improved the structure of cell parallel inside modules and module whole operation, and assembling product and safeguard convenient.
In addition to the implementation, the utility model can also have other execution mode.All employings are equal to the technical scheme of replacement or equivalent transformation formation, within all dropping on the utility model scope required for protection.
