It is mounted in, is preferably bonded on the second housing parts 130.As an alternative, damping element 135 can be with the first housing parts 120 and/or
Monomer keeper 600 is especially integrally formed in a common operation two housing parts 130 together in other words, so as to be used for
The assembling of damping element 135 expends and can keep very little.
As shown, damping element 135 is arranged in two appearances towards different directions orientation of monomer keeper 600
On face, especially on the composition surface of the monomer keeper or abutment face, wherein, the surface of monomer keeper 600 has position state
Safety structure 155.Position state safety structure 155 is at least largely prevented in the first housing parts 120 and the second housing parts
Under 130 assembled state there is the change of position state in damping element 135, be applied in accumulator battery from different directions such that it is able to be absorbed
Effect of vibration.In the embodiment as shown, battery case 110 also has two side members 125, wherein, in Fig. 4
In only illustrate in two side members 125 one.These side members 125 are in the assembled state by the first housing parts 120
So keep together with the second housing parts 130 so that prevent the first housing parts 120 from releasing from the second housing parts 130
Or second housing parts 130 release from the first housing parts 120.Here, these side members 125 and position state safety structure 155
So concur so that under the assembled state of battery case 110, largely prevent damping element 135 from occurring
Position state change.Just can be clearly visible in the embodiment as shown, monomer keeper 600 partly constitutes the second housing
The outside of the accumulator battery in other words 100 of part 130, wherein, alternatively, monomer keeper 600 can also partly constitute
The outside of one housing parts 120.
Damping element 135 is made up of the material for belonging at least one of following material group material group at least in part：Bullet
Gonosome, viscoelasticity synthetic material or entropic elasticity synthetic material.This kind of synthetic material can be in the situation by pulling force and pressure load
Lower elastic deformation, but be subsequently returned in its undeformed original configuration, thus can be advantageously carried out：Accumulator battery can be protected
100, single battery 400 is especially protected from the impact of the vibration or vibrations of hand held power machine 300.By this way,
On the one hand the mechanical robustness of accumulator battery 100 is improve, and on the other hand reduces abrasion.Additionally, accumulator can be protected
The single battery 400 of the sensitivity of group 100, and and then improve the service life and reliability of accumulator battery 100.
Damping element 135 can be made by thermoplastic elastomer (TPE), also, can during manufacture just in accumulator battery shell
120,130 damping element formed integrally of respective housings part arranged on position with battery case 110 of body 110
Or the damping element is formed on the position.The original thickness of damping element 135 so can be selected, so as in assembling
In the case of, in the first housing parts 120 and the second housing parts 130 in other words between monomer keeper 600, damping element quilt
It is compressed to the 30% to 70% of its original thickness, preferably 40% to 60%, particularly preferred 50%.By the bullet of damping element 135
Property restoring force, realization reduces gap between these housing parts 120,130 to the full extent.
Fig. 5 illustrates the sectional view according to accumulator battery of the present utility model 100, wherein, substantially can be seen here, monomer
Keeper 600 constitutes the second housing parts 130 and further also constitutes the outside of battery case 110.Damping element 135 is inserted
To the first housing parts 120 and the second housing parts 130 in other words between monomer keeper 600, wherein, the two housing parts
120th, 130 kept together by two side members not shown in Fig. 5.
In addition to described and shown embodiment, it is also contemplated that may include other modifications and combinations of features
Other embodiment.
