Abstract
The utility model provides a portable projection device capable of avoiding faulty starting. The portable projection device capable of avoiding faulty starting comprises a portable projection device body; a distance sensor is arranged on the portable projection device body; the distance sensor and the projection lens on the portable projection device body are arranged in the same plane; the power supply end of the distance sensor is connected with the battery inside the portable projection device body and depends on the internal battery of the portable projection device for power supply, and the output end is connected with the main control chip inside the portable projection device body. The portable projection device capable of avoiding faulty starting has the advantages that the portable projection device can be effectively prevented from being started faultily in faulty situations, loss of electricity is then avoided, and normal use of the projection device can be ensured.
Description
Technical field
The utility model relates to a kind of projection arrangement art, especially a kind ofly prevents from opening by mistake the projection arrangement that opens.
Background technology
At present, portable projection arrangement is very general.Because light source and the associated mechanisms power consumption of projection arrangement are higher, and portable projection device often adopts powered battery, in case projection arrangement is by error starting, then battery electric quantity will be consumed in the unwitting situation of user fast, when the user will really use projection arrangement, electric weight may be not enough.In order to overcome the above problems, be necessary to propose a kind of portable projection device that prevents error starting.
The utility model content
The technical problems to be solved in the utility model provides a kind of portable projection device that prevents error starting.
The utility model solves the problems of the technologies described above by the following technical solutions: a kind of portable projection device that prevents error starting, the range sensor that comprises the portable projection device body, installs at the portable projection device body, projection lens on this range sensor and the portable projection device body is installed in same plane, the power end of described range sensor is connected to the intrinsic battery of portable projection device, rely on the internal cell power supply of portable projection device, its output terminal is connected with the intrinsic Master control chip of portable projection device.
The utility model has the advantage of: can prevent effectively that portable projection device from being opened by being opened by mistake under error situation, and then avoid the waste of electric weight, guarantee the normal use of projection arrangement.
Description of drawings
Fig. 1 is the structural representation that the utility model can prevent the portable projection device of error starting.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model patent is further specified:
Referring to Fig. 1, a kind of portable projection device that prevents error starting of the utility model, the range sensor 3 that comprises portable projection device body 1, installs at portable projection device body 1, this range sensor 3 is installed in same plane with projection lens 2 on the portable projection device body 1.
The power end of described range sensor 3 is connected to the battery in the portable projection device body 1, relies on the internal cell power supply of portable projection device, and its output terminal and portable projection device body 1 interior Master control chip is connected.
This course of work of portable projection device that can prevent error starting is as follows: when portable projection device is activated, to at first check that by range sensor 3 portable projection device body 1 is to the distance on projecting plane, and these projector distance data are sent to Master control chip, Master control chip is judged, if this projector distance is less than setpoint distance, then judge portable projection device by error starting, Master control chip is ended start-up course and powered-down, otherwise then normal boot-strap starts.Setpoint distance can be solidificated in the Master control chip of portable projection device, also can allow the user arrange flexibly by software, thereby realizes the sensitivity of different distance.
Above-described embodiment of the present utility model only is to be explanation the utility model example, and is not to be restriction to embodiment of the present utility model.For those of ordinary skill in the field, can also make on the basis of the above description other multi-form variation and changes.Here can't give all embodiments exhaustive.Everyly belong to the row that apparent variation that the technical solution of the utility model amplifies out or change still are in protection domain of the present utility model.
Claims (1)
1. portable projection device that can prevent error starting, comprise the portable projection device body, it is characterized in that: also be included in the range sensor of installing on the portable projection device body, projection lens on this range sensor and the portable projection device body is installed in same plane, the power end of described range sensor is connected to the intrinsic battery of portable projection device, and its output terminal is connected with the intrinsic Master control chip of portable projection device.
