Abstract
The utility model discloses a portable miniature digital light processing (DLP) projector with a power supply. An alternating current power supply socket is installed on a casing, a rechargeable battery and a charge-discharge control circuit board are installed at the position in the casing, the position in the casing is close to the inner end of the alternating current power supply socket, and two ends of the rechargeable battery and the inner end of the alternating current power supply socket are correspondingly connected with the charge-discharge control circuit board respectively. During usage, when an alternating current power supply is alive, alternating current is switched in through the alternating current power supply socket to supply power for the projector to work, simultaneously, under the control of the charge-discharge control circuit board, the rechargeable battery is charged, and charging is automatically stopped until the battery is fully charged; and when the alternating current power supply is out of power or the alternating current power supply can not be switched in due to lack of a power line, under the control of the charge-discharge control circuit board, the rechargeable battery supplies power for the projector, so that the purpose of using the projector is achieved. According to the portable miniature DLP projector, the problem that the projector can not be used due to external power shortage, lack of the power line or damage of the power line is solved, and the portable miniature DLP projector suitable for being temporarily used for a short time.
Description
Technical field
The utility model relates to a kind of portable minisize DLP projector, relates in particular to a kind of self-powered portable minisize DLP projector.
Background technology
DLP projector adopts DLP imaging display technique, inputs corresponding video signal, projects larger picture image; Because it is small and exquisite so that carry that minitype projection machine is pursued, so the external electric source adapter that the general employing of the power supply of portable minisize DLP projector is connected with AC power or built-in power supply adapter are as supply unit, no matter external or built-in all needs to have the external ac power source power supply to move.But because portable minisize DLP projector carries when going out and may leave behind the external electric source adapter, or the external electric source adapter damages, or do not have power lead, or power lead damages, or AC power all can't use projector without electricity in these situations, brings loss or inconvenience to the user.
The utility model content
The purpose of this utility model provides a kind of self-powered portable minisize DLP projector with regard to being in order to address the above problem.
The utility model is achieved through the following technical solutions above-mentioned purpose:
Self-powered portable minisize DLP projector described in the utility model, on its housing AC Power supply socket is installed, position near described AC Power supply socket the inner in the described housing is equipped with rechargeable battery and charge-discharge control circuit plate, the two ends of described rechargeable battery be connected AC Power supply socket the inner respectively with the corresponding connection of described charge-discharge control circuit plate.
During use, when AC power had electricity, by AC Power supply socket incoming transport electricity, projector got electric work, charged for rechargeable battery under the control of charge-discharge control circuit plate simultaneously until be full of automatically and stop; Damage or do not have power lead or power lead to damage or AC power causes without electricity can't the incoming transport power supply time when leaving behind external electric source adapter or external electric source adapter, under the control of charge-discharge control circuit plate, be projector power supply by rechargeable battery, reach the purpose of using projector.
As preferably, described rechargeable battery is lithium battery.
Further, the position near described AC Power supply socket is equipped with charging indicator light, the power input of described charging indicator light and the corresponding connection of described charge-discharge control circuit plate on the described housing.During the rechargeable battery charging, charging indicator light is bright, extinguishes after being full of.
The beneficial effects of the utility model are:
The utility model has solved portable minisize DLP projector in use because leaving behind the external electric source adapter, or the external electric source adapter damages, or there is not a power lead, or power lead damages, or AC power can not use the problem of projector without electricity, and is fit to the interim short time and uses projector.
Description of drawings
Fig. 1 is the plan structure schematic diagram after self-powered portable minisize DLP projector described in the utility model removes loam cake.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
As shown in Figure 1, self-powered portable minisize DLP projector described in the utility model, on its housing 1 AC Power supply socket 5 is installed, housing 1 interior position near AC Power supply socket 5 the inners is equipped with rechargeable battery 4 and charge-discharge control circuit plate 6, the inner of being connected with AC Power supply socket in the two ends of rechargeable battery 4 respectively with the 6 corresponding connections of charge-discharge control circuit plate, this syndeton since accompanying drawing only for schematic diagram be not easy to the drawing not shown in the diagram.
As shown in Figure 1, rechargeable battery 4 is lithium battery; Position near AC Power supply socket 5 on the housing 1 is equipped with charging indicator light 7, the power input of charging indicator light 7 and the 6 corresponding connections of charge-discharge control circuit plate, and this syndeton is because accompanying drawing only is not easy to chart not shown in the diagram for schematic diagram.
Also show radiator fan 2 and camera lens 3 among Fig. 1, so that understand the inner structure of portable minisize DLP projector.
During use, when AC power has electricity, by AC Power supply socket 5 incoming transports electricity, projector gets electric work, simultaneously under the control of charge-discharge control circuit plate 6 for rechargeable battery 4 chargings until be full of and automatically stop, in this process, during rechargeable battery 4 charging, charging indicator light 7 is bright, extinguishes after being full of; Damage or do not have power lead or power lead to damage or AC power causes without electricity can't the incoming transport power supply time when leaving behind external electric source adapter or external electric source adapter, under the control of charge-discharge control circuit plate 6, be projector's power supply by rechargeable battery 4, reach the purpose of use projector.When with rechargeable battery 4 power supply, the projected picture lower right corner shows the battery electric quantity icon, points out the capacity of rechargeable battery 4, and glimmers at the not enough alarm of electric weight of rechargeable battery 4, electric weight thoroughly is finished then closes projector and quits work, and normally uses after charging next time again.
