Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a foldable mobile phone, and more particularly to the structure of a mobile phone when a large capacity battery pack is mounted.

[0002]

[Prior art]

 The structure of a conventional foldable mobile phone is shown in FIGS. FIG. 4 is a state diagram of a conventional foldable mobile phone when a small capacity battery pack is mounted, and FIG. 5 is a state diagram of a conventional foldable mobile phone when a large capacity battery pack is mounted.

The telephone body 41 is provided with an earpiece and a number display portion (not shown) on its inner surface, and is connected to a body opening / closing portion 42 which can be rotated 180 ° by a hinge mechanism 44 at an end portion.

A transmitter section (not shown) is provided on the inner surface of the main body opening / closing section 42.

Power is supplied from a battery pack and is usually removably attached to the outer surface (back surface) of the telephone body.

Conventionally, mobile phones have been miniaturized to be convenient to carry. For this reason, as shown in FIG. 4, a small-capacity battery pack 43 that is as small as possible has been used as the battery pack. In other words, we have selected batteries with the smallest possible battery capacity and packed them as a battery pack. However, it has the drawback of being limited in call time and standby time due to its small capacity. Therefore, as shown in FIG. 5, a large-capacity large-capacity battery pack 51 is usually provided at the same time.

[0007]

[Problems to be solved by the device]

 However, in the conventional foldable portable telephone equipped with the large capacity battery pack 51, there is a difference in weight between the telephone body 41 (including the battery pack 51) and the body opening / closing portion 42 (transmitting portion) during a call. Because of this, the balance was poor and it was difficult to hold. In addition, the large-capacity battery pack 51 has a drawback that it is difficult to grip because it is thick.

Further, when it is installed on a desk or the like, the battery pack portion is heavy and the stability is poor. Therefore, the telephone body 41 is placed sideways, and the antenna characteristics are significantly deteriorated and the standby reception is performed. There was also the drawback that in many cases it would not be possible.

The present invention has been made to solve the above-mentioned drawbacks, and an object thereof is to provide a structure of a mobile phone which is easy to use in a state where a large capacity battery pack is mounted.

[0010]

[Means for Solving the Problems]

 In order to achieve the above object, the present invention is a foldable mobile phone, and when a large-capacity battery pack is used, a large-capacity battery is provided in the main body of the telephone and the main body opening / closing portion with the main body opening / closing portion opened 180 ° The structure is such that a pack can be attached.

[0011]

[Action]

 According to the mobile phone having the above structure, the large-capacity battery pack is attached to the main body and the main body opening / closing part with the main body opening / closing part opened 180 ° from the main body of the phone, which is the same as the separate type mobile phone. The shape of the mobile phone improves the overall balance.

[0012]

【Example】

 Hereinafter, the present invention will be described in detail based on embodiments.

1 and 2 are state diagrams of a foldable mobile phone according to the present invention. FIG. 1 shows a state in which a large-capacity battery pack that is less subject to time constraints such as call time and standby time is attached, and FIG. Shows the case where a small capacity battery pack, which is convenient for carrying, is attached.

In FIG. 1, reference numeral 11 is a telephone main body, 12 is a main body opening / closing section, and 21 is a large-capacity battery pack which is a power source of the telephone main body 11. As shown in FIG. 1, a structure is adopted in which a large capacity battery pack 21 is attached to the telephone body 11 and the body opening / closing portion 12 with the body opening / closing portion 12 opened from the telephone body 11 by 180 °. By doing so, the shape will be similar to that of a separate type mobile phone, and the usability will be improved. Moreover, since it can be set up on a desk or the like, standby reception efficiency is increased.

In FIG. 2, reference numeral 11 is a telephone main body, and 12 is a main body opening / closing portion, which is the same as in FIG. 22 is a small capacity battery pack. The main body opening / closing section 12 is a transmitter section and a protective cover for the telephone main body 11 when the main body opening / closing section 12 is closed. The foldable mobile phone with the small-capacity battery pack 22 shown in FIG. 2 installed is no different in function and structure from the conventional one.

FIG. 3 shows a specific example of a method of mounting the large capacity battery pack 21. FIG. 3A shows a method called a slide method, in which a guide 31 is provided on the side of the battery pack 21. Further, guides 32 that engage with the guides 31 are also provided on the lateral sides of the main body telephone 11 and the main body opening / closing portion 12.

A battery pack fixing latch 33 for fixing the battery pack 21 is provided at the end of the main body opening / closing part 12.

Next, the battery pack 21 is mounted on the outer surface (back surface) of the telephone body 11 and the body opening / closing part 12 while sliding the battery pack 21 so that the guide 31 and the guide 32 engage with each other.

When the battery pack 21 is completely attached, the end portion of the battery pack 21 is fixed by the fixing latch 33 so that it does not come off.

FIG. 3B is a method called a hook method in which a hook 35 is provided at the end of the large capacity battery pack 21.

Then, when the main body opening / closing section 12 is rotated to be opened 180 °, the hook 35 is engaged with and fixed to the hook receiving section 34 provided at the end of the main body opening / closing section 12.

Note that the relative relationship between the hook 35 and the hook receiving portion 34 may be provided so as to be opposite.

FIG. 3C is a method called a magnet system. Instead of the hook 35 and the hook receiving portion 34 in FIG. 3B, a receiving plate 37 made of a magnetically attracted iron plate or the like, and a magnet. 36 are provided.

By mounting an option pack of the same shape on the main body instead of the large-capacity battery pack 21, a foldable mobile phone can also be applied as a car phone.

[0025]

【The invention's effect】

 As described above in detail, according to the present invention, when a large-capacity battery pack is used in a foldable mobile phone, the battery pack is mounted not only on the phone body but also on the opening / closing part of the foldable part. As a result, the shape is similar to that of a separate type mobile phone, and the balance of the mobile phone as a whole is better, which improves usability during a call. Also, when installed, it can be set upright, which improves antenna characteristics and greatly improves standby reception efficiency.

When using a small capacity battery pack, it can be used as a conventional foldable portable telephone.
