Description
Technical field
The utility model relates to a kind of lithium battery, relates in particular to a kind of self-regulated clamping device that is used for the lithium battery group of keeping stable thermal expansion rate of change.
Background technology
Need be in order to supply moments such as electric automobile, oily electric hybrid vehicle, electric motor car, electric bicycle, electric ship, electronic hand tool than the electric power of the product of great start-up current; Therefore lithium battery is a developing goal with high-performance, big capacity all; But also therefore produce two problems: expand with heat and contract with cold, and heat radiation.
About the aspect of expanding with heat and contract with cold, if the positive pole of lithium battery and negative pole do not apply for a long time the chucking power of appropriateness, and let it expand with heat and contract with cold naturally, through the time durable after, can influence its life-span greatly because of internal structure expansion rate of change.Therefore, generally use foam and coat, but the chucking power of foam is unstable, the amplitude of expanding with heat and contract with cold variation is let nature take its course, and can't the expansion rate of change be controlled in certain scope.
The utility model content
The purpose of the utility model is to provide a kind of self-regulated clamping device that is used for the lithium battery group, can occur loosening because of the reason of expanding with heat and contract with cold after having solved existing lithium battery and installing or pushes the problem that influences useful life.
For addressing the above problem, the technical scheme that the utility model is taked is:
A kind of self-regulated clamping device that is used for the lithium battery group is installed between shell and the fin near shell, comprises that fixed head, portable plate and elastic component constitute, and described fixed head and portable plate are provided with at least one guide pin bushing, and elastic component is installed in the guide pin bushing.
For making the utility model play better technique effect:
The above-mentioned guide pin bushing of technical scheme further is fixed on the fixed head ringwise; Portable plate is provided with protuberance; The outer wall of described protuberance and the inwall of guide pin bushing are complementary, after elastic component is arranged on protuberance insertion guide pin bushing, in the gap that forms between the end of protuberance and the fixed head.
The above-mentioned guide pin bushing of technical scheme further is fixed on the portable plate ringwise; Fixed head is provided with protuberance; The outer wall of described protuberance and the inwall of guide pin bushing are complementary, after elastic component is arranged on protuberance insertion guide pin bushing, in the gap that forms between the end of guide pin bushing and the fixed head.
The circle that the above-mentioned guide pin bushing of technical scheme further is hollow is fixed on the fixed head, and portable plate is provided with protuberance, and the outer wall of described protuberance and the inwall of guide pin bushing are complementary, and elastic component is arranged on the middle vacancy of guide pin bushing.
The above-mentioned elastic component of technical scheme further can be the compression spring, also can be elastic caoutchouc.
Adopt the beneficial effect that technique scheme produced to be: the chucking power that the expansion rate of change of battery can be produced by elastic component control and is able to maintenance and stablizes, and prevents its excessive expansion and influences the life-span.
