What deserves to be mentioned is, because the functional diversities of present portable computer, power consumption is also higher, generated output demand to battery module also increases day by day, the working temperature of battery module is wayward in the temperature range of safety, causes battery module in use to produce blast or burning because of overheated (overheating) easily.
Summary of the invention
The invention provides a kind of battery module, it can prevent that battery module from producing blast or burning because of working temperature is too high.
The invention provides a kind of portable electronic devices, it has above-mentioned battery module, burns or explodes because of battery module with other assembly that prevents portable electronic devices and damage.
The present invention proposes a kind of battery module, and it comprises housing, a plurality of battery, circuit board, the caisson that stores fire-retardant gas and seal.Battery and circuit board are to be disposed in the housing, and circuit board is to electrically connect with battery.Caisson is to be disposed in the housing equally, and adjacent with battery and circuit board.In addition, caisson has an opening, and seal is located at opening part, with flame-resistant gas in caisson.When the temperature in the housing was higher than preset temperature (for example: 60 ℃), the seal that is sealed in opening can melt, and fire-retardant gas can leak to caisson from opening.
In one embodiment of this invention, the material of seal is a wax.
In one embodiment of this invention, fire-retardant gas is carbon dioxide.
The present invention reintroduces a kind of portable electronic devices, and it comprises a body and above-mentioned battery module, and battery module is to be equipped on body.
The present invention is provided with the caisson that a storage has fire-retardant gas in battery module, wherein the opening of caisson is provided with a seal, to block fire-retardant gas leak.When battery or the working temperature of circuit board are higher than the preset working temperature and cause temperature in the battery module to be higher than preset temperature (for example: 60 ℃), the seal that is sealed in opening promptly can be subjected to temperature effect and melt, fire-retardant gas promptly can leak to housing from the opening of caisson, and then makes battery module be difficult for having the situation of blast or burning to take place.In other words, the present invention can prevent that other assembly of portable electronic devices from burning because of battery module or blast damages, and causes more serious loss.
For above-mentioned feature and advantage of the present invention can be become apparent, preferred embodiment cited below particularly, and cooperate appended graphicly, be described in detail below.
Description of drawings
Figure 1A is depicted as the schematic diagram of the portable electronic devices of one embodiment of the invention.
Figure 1B is depicted as the schematic diagram of the battery module of Figure 1A.
The battery module that Fig. 1 C is depicted as Figure 1B removes the schematic diagram behind the housing partly.
Embodiment
Figure 1A is depicted as the schematic diagram of the portable electronic devices of one embodiment of the invention, and Figure 1B is depicted as the schematic diagram of the battery module of Figure 1A, and the battery module that Fig. 1 C is depicted as Figure 1B removes the schematic diagram behind the housing partly.Please also refer to Figure 1A, Figure 1B and Fig. 1 C, the portable electronic devices 10 of present embodiment is a portable computer, the battery module 100 that it comprises body 12 and is disposed at body 12.Above-mentioned battery module 100 can supply portable electronic devices 10 runnings required electric power.Thus, the user can not have under the environment of external power supply by battery module 100 power supplies, with operation portable electronic devices 10.
In the present embodiment, battery module 100 comprises housing 110, a plurality of battery 120, circuit board 130, stores caisson 140, and the seal 150 of fire-retardant gas.In the present embodiment, battery 120 is to be disposed in the housing 110 with circuit board 130, and circuit board 130 and battery 120 electric connections, with the charging/discharging voltage of control battery 120.
In addition, the caisson 140 of present embodiment is to be disposed in the housing 110 equally, and adjacent with battery 120 and circuit board 130.Caisson 140 is provided with an opening 142, and seal 150 is to be located at opening 142 places, with flame-resistant gas in caisson 140.
From the above, present embodiment is to be example with 6 battery 120, and these battery 120 for example are to separate by the dividing plate (not shown) each other, and caisson 140 for example is a side of being located at battery 120 and circuit board 130.In the present embodiment, seal 150 its materials of being located at opening 142 places are wax or other preset temperature (fusing point) between 60 ℃～80 ℃ solid-state high-melting-point material, and fire-retardant gas for example is carbon dioxide (CO2) or nitrogen inert gases such as (N2).Thus, when battery 120 or the working temperature of circuit board 130 is higher than the preset working temperature, and during near burning-point (burning-point is about 100 ℃), temperature in the battery module 100 promptly can be higher than 80 ℃, and the seal 140 that is sealed in opening 142 promptly can melt, and make it for example is can leak to housing 110 from opening 142 by the fire-retardant gas of high pressure compressed in caisson 140, and then the situation that makes battery 120 or circuit board 130 not have blast or burning takes place.
More particularly, temperature in battery module 100 is higher than 80 ℃, and be sealed in seal 140 fusings of opening 142, so that fire-retardant gas leaks to housing 110 from the opening 142 of caisson 140, promptly be full of in the housing 110 and for example be that the carbon dioxide (CO2) or the fire-retardant gas of nitrogen (N2), battery 120 or circuit board 130 promptly are difficult for having the situation of burning or blast to take place.
In sum, preferred embodiment of the present invention is that the caisson that a storage has fire-retardant gas is set in battery module, and surpass the temperature range of safety when battery or the working temperature of circuit board, and when causing bulk temperature in the battery module to be increased to a preset temperature, the seal that is sealed in opening promptly can melted by heat.After seal meeting melted by heat, the fire-retardant gas that is stored in caisson promptly can leak to whole housing from opening, be difficult for promptly in the housing that combustion-supporting gas the is arranged existence of (for example being oxygen), battery or circuit board promptly are difficult for having the situation of burning or blast to take place.Thus, the user has good fail safe when for example being the portable electronic devices of portable computer using, and other assembly of portable computer also is difficult for damaging because of battery module burning or blast, causes more serious loss.
Though the present invention discloses as above with preferred embodiment; right its is not in order to limit the present invention; have in the technical field under any and know the knowledgeable usually; without departing from the spirit and scope of the present invention; when can doing a little change and retouching, so protection scope of the present invention is as the criterion when looking claims person of defining.
