Abstract
The utility model relates to a precision balance device and a battery module thereof. The battery module comprises a battery cell, a battery charging part and a housing, wherein the battery cell and the battery charging part are built in the housing. The battery module is characterized by further comprising a heat radiating bottom plate supported by a heat conducting material and used for covering the housing; the outer side surface of the heat radiating bottom plate is exposed in the air; and the inner side of the heat radiating bottom plate is connected with the battery charging part for the convenience of heat transfer.
Description
Technical field
The utility model relates to battery module, relates in particular to the structure that weighing apparatus is used battery pack.
Background technology
Accurate weighing apparatus such as the precision balance class uses battery can have good mobility as power supply, but in use battery live part circuit has the phenomenon that temperature raises more or less, the variation of temperature or cause the unsteadiness of accurate weighing apparatus, this point will be avoided as far as possible.
The utility model content
The purpose of this utility model is to provide a kind of battery module, and it has good heat dispersion.
For realizing the battery module of described purpose, comprise battery battery core, battery live part and shell, battery battery core and battery live part are built in the shell, it is characterized in that, also comprise radiating bottom plate, it is supported by thermally conductive materials, its closure shell, and its outer surface is exposed in the air outward, and inboard and battery live part link together so that can carry out heat transmission.
In the preferred embodiment of described battery module, radiating bottom plate and battery live part are directly fitted.
In the preferred embodiment of described battery module, radiating bottom plate and battery live part centre arrange Heat Conduction Material and fit together.
In the preferred embodiment of described battery module, described battery live part is the charger backplate that disposes charging circuit.
In the preferred embodiment of described battery module, described radiating bottom plate is metal base plate.
In the preferred embodiment of described battery module, described shell is the flame-retardant plastic shell.
In the preferred embodiment of described battery module, described battery battery core is lithium cell or lighium polymer battery core.
A kind of accurate weighing apparatus comprises battery module, it is characterized in that, this battery module is described battery module.
In the preferred embodiment of described accurate weighing apparatus, this precision weighing apparatus is precision balance, and this battery module is arranged on the bottom of balance body.
The design of battery module is so that the variation of temperature concentrates in the module, and most heat is all got rid of by radiator portion.Make the temperature of balance internal environment relatively stable, obtain stable weighing result.In the invention human experimentation, the internal temperature that uses this structure heat radiation can make balance is very fast stable, and maximum temperature also can be lower more than 10% than the temperature of not using this structure, and very large Practical significance is arranged.

Fig. 2 is the profile along A-A direction among Fig. 1.
Fig. 3 is the partial enlarged view at B place among Fig. 2.
Embodiment
As shown in Figures 2 and 3; battery battery core 1 can be lithium cell or lighium polymer battery core; perhaps other are suitable for the battery core as the power supply of weighing apparatus; it mainly plays the electric power storage effect; the downside of battery battery core 1 is provided with battery-heating part 4; in embodiment as shown in Figure 3; it is the charger backplate with charging circuit; battery-heating part 4 is except disposing the pcb board of charging circuit; can also be the acquisition function module that disposes the information such as battery electric quantity, it be delivered on the mainboard of weighing apparatus inside by connector.Battery battery core 1 and battery-heating part 4 are built in the shell 2; shell 2 preferably is the anti-flammability battery case; to improve the fail safe of battery module; effectively place the fortuitous events such as Plastics Combustion that heat raises and causes; the bottom of shell 2 is by heating panel 3 cappings; heating panel 3 and battery-heating part 4 centres arrange Heat Conduction Material 5 and fit; Heat Conduction Material 5 can be the material of good heat conductivity; copper for example; aluminium etc.; heating panel 3 also is the material of good heat conductivity; such as aluminium etc.; Heat Conduction Material 5 closely fits together charger backplate and radiating bottom plate; can accelerate heat transmission, the heat conductivility of Heat Conduction Material 5 can be better by the heat conductivility of heating panel 3, and heating panel 3 and Heat Conduction Material 5 can be made of one.Direct and the contact with air of the outer surface of heating panel 3, like this, the heat that battery-heating part 4 produces just is delivered to heating panel 3, heat is emitted in the air by heating panel 3, the heat that produces of battery module just can be to not the exerting an influence of the gravity sensor in the weighing apparatus or other parts like this, thereby prevent weighing apparatus because the variations in temperature of battery module and the unsettled situation of precision.
As shown in Figure 1, embodiment of the present utility model is take electronic balance 11 as example, and battery module 10 is configured in the bottom of electronic balance 11, the directly dissipation from air of heat that battery module 10 produces.
The structure of aforesaid battery module is not limited to use on electronic balance 11, can also use on other accurate weighing apparatus, described " accurate weighing apparatus " if refer to not use radiator structure then its precision with affected weighing apparatus.
Battery module 10 is placed on a day flat bottoms, uses screw or other retention mechanisms and weighing apparatus body to fix.Can make an independently next independent placing battery module in space in weighing apparatus body enclosure interior during with this battery module, can better completely cut off heat like this.
