Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application field] The present invention relates to a liquid crystal television.

[Conventional technology]

Conventionally, a small-sized liquid crystal television has a configuration in which a battery box for storing a battery is provided inside the small-sized liquid crystal television, or only receives power supply from an external source such as a household AC power supply or a cigarette lighter socket of an automobile. I was

[Problems to be solved by the invention]

However, in the former configuration of the prior art, the ratio of the volume of the battery to be stored in the volume of the small liquid crystal television is high, and there is a problem that the small liquid crystal television is enlarged.

Especially in a room with an AC power supply or in a car with a cigarette lighter socket, the battery box inside the small LCD TV is completely unnecessary, which not only deteriorates portability but also is installed on a narrow desk or in a car. Made it difficult or even impossible.

Further, in the latter configuration of the prior art, the range of use is limited to a room having an AC power supply or an automobile having a cigarette lighter socket, and the largest range of a small liquid crystal television which can be easily viewed anytime and anywhere. There is a problem that the advantage is significantly reduced.

An object of the present invention is to provide a liquid crystal television that can be easily viewed anytime and anywhere and that can be reduced in size as needed, without the disadvantages of the related art.

[Means for solving the problem]

The present invention is directed to a liquid crystal television capable of receiving power from a battery box for storing batteries or an external power source other than the battery box, wherein a plurality of convex type first members provided on an outer surface of the battery box are provided. A plurality of recessed second engaging portions for inserting and engaging the mating portions are provided one each in an upper region of a plane corresponding to a back surface of a surface having a liquid crystal screen of the liquid crystal television body and in a lower region. Two are provided apart from each other,
The battery box fixed to the liquid crystal television is made detachable by the engagement of the first and second engagement portions, and the rear surface does not have a protruding projection.

〔Example〕

 An embodiment of the present invention will be described with reference to the drawings.

FIG. 1 is an example of a small liquid crystal television according to the present invention. In the figure, 1 is a small liquid crystal television main body, 2 is a detachable battery box, 3 and 4 are claws for attaching and detaching the small liquid crystal television main body 1 and the battery box 2, and 5 is a small liquid crystal television 1 and the battery box 2. Connector for establishing battery continuity between
Is an external power input unit that receives external power supply, and 7 is AC
It is connected to the external power input unit 6 by a power cable from a power source or a cigarette lighter socket.

The small liquid crystal television main body 1 has holes 1a and 1b which are engaging portions for hooking the claws 3 and 4 which are engaging portions on the back surface, and further has a terminal 1c for receiving electric supply from the connector 5. have.

The nail 3 has a hook 3a to the hole 1a of the liquid crystal television body 1 and an operation unit 3b. The claw 3 is normally pushed up by a spring or the like, and slides down by pushing down the operation unit 3b.

When attaching the battery box 2 to the main body 1 of the small liquid crystal television, the claw 3 and the claw 4 are inserted into the holes 1a and 1b with the operation portion 3a being pushed down and the hook portion 3b being slid downward. Here, when the operation unit 3a is released, the claw 3 slides upward by a spring or the like, the hook 3b and the claw 4 are hooked in the holes 1a and 1b, and the battery box 2 is fixed to the small liquid crystal television main body 1. At the same time, the connector 5 is connected to the terminal 1c to achieve electrical conduction.

When removing the battery box 2 from the small LCD TV main body 1, press down the operation unit 3a to set the hooking unit 3b.
Is disengaged from the hole 1b by sliding it downward, and the hook 4 is disengaged from the hole 1b by further shifting the battery box 2 upward.

As described above, the battery box 2 can be removed from the main body 1 of the small liquid crystal television.

[Effect of the invention]

As described above, according to the present invention, there is no need to provide a battery storage space in a part of the liquid crystal television main body, so that the liquid crystal television main body can be made very small and a liquid crystal television excellent in portability can be realized. It has the effect of being able to.

Further, a concave engaging portion is provided on the flat surface of the outer surface of the liquid crystal television main body so that the battery box fixed to the liquid crystal television by the engagement can be detached, and the rear surface has no protruding projection. Therefore, there is no extra projection on the surface having the engaging portion on the back of the liquid crystal television. Therefore, when the liquid crystal television is used by using the power supply from the external power supply with the battery box removed, no projections or the like can be formed on the rear surface of the liquid crystal television.

Also, since one engaging portion is provided in the upper region of the plane corresponding to the back surface of the surface of the liquid crystal television body having the liquid crystal screen, and one at the end of the lower region, it is fixed at three points. This has the effect that the connection between the main body and the battery box becomes very strong.

Also, by mounting the battery box, it is possible to watch television even in an outdoor room without an external power supply such as an AC power supply or a cigarette lighter socket.

In addition, depending on the type and quantity of batteries to be stored, by preparing a battery box according to the purpose and application, it is possible to use one small LCD TV for small portable, long-time use etc. The functionality and expandability of the small LCD TV can be further expanded.
