Technical field

The invention relates to batteries and headphones for mobile phones. Batteries are designed to allow hot-swap. The headphones are designed especially for mobile phones placed on the wristband and allow discreet listening with easy handling.

BACKGROUND OF THE INVENTION

For easy handling, mobile phones are available on the wrist strap. The disadvantage of these phones lies in the low battery capacity, which must be smaller in size than that of conventional hand-held mobile phones, as there is no room for large batteries on the wrist. For this reason, the operation of the mobile phone on the wristband is limited in time to a shorter time than that of conventional mobile phones, and relatively frequent battery replacement is required if the battery cannot be recharged while the capacity is running low. This manipulation is tedious because it is necessary to remove the bracelet from the wrist. In addition, when replacing the battery, the operation of the mobile phone is interrupted and must be reset after replacement, ie there is a power failure at that time. For these reasons, cell phones on the bracelet are not used very often. The problem of battery replacement is also common in mobile phones, where replacement means putting the phone out of operation. Replacing the batteries is also mechanically demanding, as the phone cover has to be removed before removing the battery. In addition, with existing phones in the bracelet, it is not possible to hold the phone to your ear and talk discreetly, but a speakerphone is used. An alternative is a handset communicating via Bluetooth. But it is quite large, worn mostly in the pocket and therefore requires a relatively complex handling to deploy. In addition, it needs its own battery and therefore recharging. The object of the invention is a device which would allow simple battery replacement during operation. Furthermore, with mobile phones on the bracelet the possibility of putting the phone on the ear without or just with simple handling of the handset. In addition, the handset does not need its own battery, which would have to recharge.

Disadvantages are eliminated and the object of the invention is fulfilled by a mobile phone with a battery exchange during operation, where in addition to the service battery there is also a backup battery which keeps the phone in operation when the service battery is replaced. It is possible to replace both batteries gradually without interrupting operation. The batteries may be stored in a standby case, which may preferably include a miniature charger.

to recharge the batteries in the field. In order not to need to replace the backup battery, it may have the minimum capacity necessary to maintain operation while the main battery is being replaced and recharge from an external charger or an operating battery when an external charger is not available. In order to achieve a higher voltage for charging than the idle voltage of the battery without recharging, it is advantageously possible to use operating batteries with a higher idle voltage than the backup batteries. In this case, the mobile phone is preferably adapted to tolerate the voltage dissipation from the operating and backup batteries, for example by reducing the voltage from the main battery. To avoid having to adapt the mobile phone to voltage, it is advantageous to use two backup batteries which are connected in parallel at the time of charging, at the time of replacing the operating battery in series. A suitable charging current is provided by a resistor or electronic recharger control unit that turns off charging after charging. Switching from parallel to serial connection can be done by mechanical or preferably electronic switch. After facilitating the replacement of the battery, it is advantageously possible to place them on the guide rails, after which they can be pulled out or in a housing. After sliding into the position where the battery and telephone contacts abut, the batteries are preferably locked by a latch or a manual lock operated by the user. For easy ejection, the lock can be used as a handle to push or pull out the battery. For mobile phones on a bracelet, the battery is placed in a flat case preferably located on the bottom of the wrist-mounted phone, from which the battery can be pulled aside without having to unclip the bracelet. Preferably, the mobile phones on the wristband may have a handset placed on the wristband so that it can be attached to the ear without detaching it only by moving the arm on which the mobile phone is positioned. This is possible by placing the handset preferably on the lower part of the bracelet, that is on the opposite side to the mobile phone, provided it is worn on the upper side of the wrist. This requires placing the palm on the head above the sleep so that the handset can be placed on the ear, in a not too comfortable position and is therefore only suitable for short standby use. Allowing the handset to be held by your fingers with your fingers is made possible by removing the handset from the holder on the phone when the bracelet is placed on the left hand. The advantage of this manipulation is that the microphone does not have to be moved, it can remain fixed to the wristband because when the earpiece is placed on the ear, the fingers are close to the mouth and are able to register speech. This will advantageously allow one-way connection of the telephone with the handset, instead of the two-way connection in case of relocation of the microphone, ie the handset. The unidirectional connection to the handset can advantageously be provided by radio communication with a miniature transmitter and receiver. Advantageously, the handset can be connected alternatively with a cord wound on a reel located on the bracelet from which the cord unwinds when the handset is removed from the holder and is retracted automatically. It is also possible to advantageously use a helical stretch cord. With the preference to wear the cell phone in a wristband on the top of the wrist, that is, away from the palm, it is advantageously possible to have a microphone and a removable handset located on the underside of the wristband, i.e. the side facing the palm. In this case, the handset and microphone are preferably connected by cable or wirelessly to the telephone. The cable may preferably be pulled on or over the bracelet. Advantageously, on this side of the wristband facing the palm, i.e. opposite to the mobile phone, the backup and operational batteries may be conveniently located in a case attached to the arm and held by the wristband from which the batteries may be pulled aside as described above. The connection to the mobile phone is realized by a cable preferably located on or in the wristband. The battery cable as well as the microphone and the telephone can be brought to the mobile phone permanently or preferably via a connector. In the case that the backup small-capacity battery is preferably used only to ensure operation during the battery replacement period, it can advantageously be placed in the mobile phone without being able to remove it without interruption of operation and removably without interruption of operation. Advantageously, it is also possible to recharge the battery in a mobile phone without removing it from the charger cable, or from a backup large capacity battery that can be carried in a pocket and recharged as needed when power is available.

Exemplary embodiment

Fig. 1 shows the mobile phone 1 in front view with the battery case 2, which is open from the front for insertion of the batteries 5 shown in Fig. 2, with the flexible battery contacts 4, which are connected for parallel connection of the batteries 5 2 shown in FIG. 2 and connected to the mobile phone 1 shown in FIG. 2. The contacts of the battery 7 shown in FIG. Advantageously, the device described can be applied to a mobile phone placed on the wristband 3.

Fig. 2 shows a section A - A of the mobile phone 1 in side view, where the batteries 5 can be inserted into the housing 2. The ejection is facilitated by the levers 6, which are shown in the tilted position.

In Fig. 3, the battery 5 is seen from above, wherein the lever 6 shown in the tilted position is rotated around the pin 10.

FIG. 4 shows the batteries 5 inserted in the housing 2, with the contacts of the battery 7 abutting the spring contacts 4 of the housing 2.

Giant. 5 shows the housing 2 in a top view in section B-B, where the battery 5 is inserted therein. The lever 6 is in the tilted position.

Giant. 6 shows the same view as in FIG. 5, but with the lever 6 in the stowed position, wherein the battery 5 is pressed against the spring contacts 4 of the housing 2 and secured in the housing by the end of the lever 12 pivotable according to the pin 10 through the slot in the housing 11 and leaning against the wall The lever 6 is locked in the stowed position by a spring 8 which engages the projection 9 on the case 2. The batteries 5 are connected in parallel as described in Fig. 1. When replacing the battery, the lever 6 moves to the position shown 5 and by pulling on the lever 6, it is pulled out of the housing during operation of the mobile phone 1 which is maintained by the second battery. Advantageously, the charged battery may be inserted in the manner described and the second battery may likewise be replaced. The batteries are replaced gradually to maintain operation. The advantage of this replacement is that the operation of the mobile phone 1 will not be interrupted, i.e. the advantage is that it is possible to use a battery of less capacity than mobile phones that do not allow battery replacement during operation and only interrupt the operation in a mobile phone, which is only possible when access to the power network is available. Therefore, non-rechargeable batteries in phones must provide longer operation and have larger dimensions. The advantage of replacing the battery during operation also applies to mobile phones in a wristband placed on the wrist, since there is no need to unclip the wristband when replacing the battery, since the battery can be slid aside by the wrist.

Giant. 7 shows a mobile phone fa in which only one battery 5 is hot-swappable, which maintains the small-capacity batteries 16, which are preferably recharged from the battery 5, particularly after the charged battery 5 has been inserted. which is set to be sufficient to operate the mobile phone 1a for the time of replacing the battery 5 maintains the operation.

Giant. 8 shows a diagram for recharging a small capacity battery 16 from a battery 5, wherein the small capacity batteries 16 preferably have half voltage than the batteries 5 and are connected in parallel by a switch 17, which is three segment for charging. Charging 19 measures the charging voltage on the small-capacity batteries 16 and when it corresponds to the charged state, it automatically switches the small-capacity battery in series by the switch 17 it controls. This may preferably be a solid state made, for example, of semiconductors. The switch 17 is shown in a parallel charging state. By switching to the second position, the small-capacity battery 16 is connected in series to the battery 5 for powering the mobile phone 1, which can now be removed for replacement.

Giant. 9 shows an automatic electronic charging unit 19a which also regulates the charging current and switches the small-capacity battery 16 from a serial to a parallel circuit for charging from the battery 5 and back for operation. It also allows charging from the 220V mains via port 20.

Giant. 10 shows a housing 2a for storage batteries 5, preferably connected by a connection 15a to an automatic electronic charging unit 19b. This allows the spare batteries 5 to be charged from the 220V mains via port 20 as needed and kept ready for replacement. The electronic rechargeable unit is removable from the case for easier battery transport, which in this case can be recharged from a standard external charger via the connector socket 45 for its connection.

Giant. 11 shows a mobile phone 1 mounted on a wristband 3 enclosing a wrist 26, wherein the batteries 5 are removable by means of levers 6, one of which is shown in the tilted state. Removal is possible in the direction of the arrow 27 according to the wrist 26 during operation of the mobile phone 1 without detaching the bracelet from the wrist 26. Preferably, a microphone 21 is attached to the underside of the wristband 21 connected to the mobile phone 1. advantageously placed handset connected via spiral cable 22 through connector 25 to mobile phone 1. In case no loud traffic of mobile phone 1, which can be switched by pushbutton 28, is required, the handset 23 is functional when the telephone connection is activated and can be heard by tapping lower wrist 26, on the ear. For a more comfortable operation, the handset 23 can preferably be removed from the holder 29 where it is removably slid, with the opposite hand to which the bracelet 3 is embraced and inserted into the fingers 30 where it is shown as the handset 23a with the cord 22 being flexible extends to cable 22a. It is now possible to conveniently place the earpiece 23a on the ear and listen discreetly. The advantage of cable connection 22 is, in particular, that the handset is supplied with power from the mobile phone 1 and does not need a battery as if it were a wireless connection.

Giant. 12 shows a detail of the application of the earpiece 23a held in the fingers 30 to the ear 33 after being removed from the holder 29. It can be seen that the microphone 21 mounted on the wristband 3 is at a relatively small distance in this wrist position 26 when the earpiece 23a is held on the ear 33. from the mouth 34, which is favorable for taking a call. The handset 23a is preferably wirelessly connected in this example via a unidirectional radio link 35 provided by the transmitter 32 and the receiver 31 The fact that preferably only the handset and not the microphone is placed on the ear means that it is easier to handle, the handset can be adapted in the ear so as to hold it and does not need a bi-directional connection compared to the handset where the microphone is, so it is less bulky, the receiver 31 is simpler than the bi-directional needed for the handset and takes less power from the battery or accumulator 36 placed in the handset.

Giant. 13 shows a mobile phone 1 mounted from above on a bracelet 3. wherein the batteries 5 are mounted from below on a bracelet 3 and connected by a cable 46 to a mobile phone. An alternative location for the microphone 21 is the microphone 21a on the housing 2a.

Giant. 14 shows the mobile phone 1 worn from underneath the wrist 26, the microphone 21 being located in the mobile phone L

Giant. 15 shows a mobile phone 1 in which a reel 37 with a rotating spool 39 is mounted from below the bracelet 3, from which the cable 38 unwinds when the handset is removed from the holder 29. When the handset is inserted back into the holder 29, the cable 38 is wound back onto the spool 39, which is provided by a helical spring 40 that extends as the cable 38 is unwound. The latter secures the connection of the handset 23 to the mobile telephone 1 by means of a cable 41, preferably by means of flexible metal slots 42 which abut the metal double-ring on the spool 39 to which the cable 38 is connected, thus ensuring the connection of both cables even when the spool 39 is rotated.

Giant. 16 shows in detail a reel 37 with a spool 39 with an annular ring 43 against which resilient busses 42 are connected to the cable 41. The spool rotates about an axis 44.
