Abstract
The utility model relates to a battery pack which comprises a shell, a battery cell assembly and an electrode, wherein the shell is formed by combining an upper cover and a lower cover; the battery cell assembly comprises at least one battery unit and a bracket for containing the battery units. The battery pack is characterized in that the bracket as well as the upper cover and the lower cover are respectively provided with a columnar plug-in structure; each columnar plug-in structure comprises a limiting pole and a limiting hole, wherein during assembly, the limiting pole is inserted into the limiting hole. Because the limiting pole in the plug-in structure on the battery unit bracket is respectively combined with the limiting holes of the upper cover and the lower cover of the battery pack, the battery cell assembly and the shell have high integrity, and when the battery pack drops, the plug-in limiting pole on the battery unit bracket can deform at the drop moment to buffer the impact of the battery cell assembly on the shell during drop. Therefore, the upper and lower covers of the shell are not easy to be connected in a staggered mode to separate the shell after drop.
Description
Technical field
The utility model relates to a kind of power brick.
Background technology
Power brick is conventional electric tool assembly, for example, in garden instrument, and for example electric grass mowing equipment, electronic blower, electric chain saw.In order to lengthen working hours, power brick is removable independent assembly.The energy of power brick storage is very large, and energy density is also high, for the common power brick of safety all will have certain anti-dropping capability.Existing power brick is conventionally by battery core assembly, and the parts such as power brick upper cover, power brick lower cover form.For machining accuracy error, and assembling demand, when the upper cover of battery core assembly and power brick and lower cover have assembled, there is fit clearance in shell and battery core assembly that power brick upper cover and lower cover form, and shell can not be located battery core assembly completely.When power brick is fallen, the effect battery core due to inertia when shell lands can jump downwards in the moment of falling in shell, and was impacted.Because the weight of battery core assembly itself accounts for greatly 70% of whole power brick overall weight, relative thin weak battery pack housing will directly be born the impact of battery core assembly, and then causes the connection generation dislocation of upper cover and lower cover to cause upper and lower covers separately.
In order to prevent the generation of above-mentioned situation, better solution is that battery core assembly is formed to the entirety that can not relatively jump with upper and lower covers.Power brick on the market, for battery core is fixed, often adopts two-sided foam to fix battery module and lower cover or upper cover, and foam can make battery assembly become as a whole with upper and lower covers, and has certain shock attenuation result.But foam clings battery core assembly is inconvenient to disassemble, can does over again and make troubles for large-scale production like this.Adopt the mode of foam effectively upper cover and lower cover group not to be combined into an entirety rigidly simultaneously.For example, if connect comparatively fragility or the battery core assembly increase volume and weight itself of structure (screw and screw stud structure) of upper cover and lower cover, still easily occur the situation that upper and lower covers connecting staggered, upper and lower covers are separated.
Utility model content
For addressing the above problem, a kind of power brick, it comprises: shell, battery core assembly, electrode; Described shell is combined by upper cover and lower cover, and described battery core assembly comprises at least one battery unit and holds the support of battery unit; It is characterized in that: described support and upper cover and lower cover arrange column to inserting structure, inserting structure is comprised to limited post and spacing hole, the limited post described in when assembling inserts in spacing hole.
Preferably, described limited post is formed by least two discrete cylinders.
Preferably, described upper cover and lower cover joining place form gusset and slot, and when upper cover and lower cover assembling, described gusset inserts in slot.
Preferably, described limited post is that tool is jaggy cylindrical.
Preferably, described spacing hole is cylindricality, and it has the Kong Zhu of hollow, and the both sides of spacing hole have the stiffener being wholely set.
Preferably, have the spine of the semicircle protuberance that battery unit is installed on described support, form the paddy portion lower than spine between spine, described spacing hole is arranged in paddy portion.
Preferably, described support is connected and is formed by Part I and Part II.
Owing on battery unit support, the limited post of inserting structure being combined with power brick upper cover and lower cover spacing hole respectively, now battery core assembly and housing have good globality, in the time that power brick is fallen, can there is deformation in the insertion limited post in the moment of falling on battery unit support, the impact of battery core assembly to housing when buffering is fallen.Like this, the upper and lower covers of housing is not easy to occur connecting staggered housing separately after falling.
