Description

Chair with detachable seat

Technical Field

The utility model relates to a little table of seat, more exactly say, relate to a little table of seat that can wirelessly charge. The utility model relates to a seat with this little table of seat.

Background

Charging devices have not been provided on aircraft to date. The passenger takes the machine to go on a journey and carries products such as treasured that charges with oneself to charge for the cell-phone, and this type of product is generally heavy, carries inconvenience, and the charging wire also often rolls into a group.

The Wireless Power Consortium (WPC) published the international wireless charging standard "Qi" compatible with the first rechargeable electronic device in the industry in 2010. The Qi standard is a charging technology adopting electromagnetic induction, can realize the function that the electronic equipment can be wirelessly charged by being in close contact with the charging equipment, and realizes the universality of wireless charging. Fig. 1 shows the working principle of electromagnetic induction wireless charging, namely faraday's law of electromagnetic induction, when current passes through a coil, a magnetic field is generated, the generated magnetic field forms voltage, when voltage is applied, current is generated, and when current is applied, charging can be performed. The current passes through the power transmitting coil (as shown on the left side of fig. 1) to generate a magnetic field, and when the magnetic flux changes, the power receiving coil (as shown on the right side of fig. 1) in the magnetic field induces current, thereby transferring energy from the transmission section to the receiving end. The wireless charging technology is very safe, and the magnetic field and the external induction generated by the coil are very weak, so that the flight safety is not influenced; during charging, no electric shock is caused no matter how the body of the user touches, and the body health of passengers is not influenced. To date, many well-known enterprises, including philips, nokia, samsung, sony ericsson, etc., have joined the WPC alliance and adopted this wireless charging standard in the field of smart phones. As long as there are products of different brands identified by Qi, the charging can be carried out by a Qi wireless charger.

At present, a wide variety of wireless charging devices capable of charging portable devices such as mobile phones and tablet computers exist in the market, for example, nokia corporation introduced a wireless charging pad with a model of DC-50 in 2013 in the world meeting in nokia, and google corporation introduced a wireless charging base supporting Nexus 4, Nexus 5 and Nexus 7. The wireless charging devices can definitely solve the problem that the charging cable is bound to the user to a certain extent, but when a passenger takes the airplane, the user needs to carry one device in addition to a mobile phone and a tablet personal computer, and convenience brought by the wireless charging devices is greatly reduced.

In recent years, the "power packs" have become increasingly strict in terms of the regulations, such as the number and capacity, of the "power packs" carried by the aircraft, because of the frequent occurrence of an explosion event due to unstable performance of the power packs.

SUMMERY OF THE UTILITY MODEL

Based on this, the utility model aims at providing a little table of seat, more specifically say, provide a little table of seat that can wirelessly charge, be equipped with in the little table of seat and be used for the power transmitting device who wirelessly charges for portable electronic equipment, and this power transmitting device has the power transmission coil. The seat tablet is mounted at the seat. When the seat tablet is powered on, the power transmission coil built in the seat tablet generates a magnetic field. When a mobile phone, a tablet computer, a notebook computer and the like with a wireless charging function are placed on the small table plate, namely, the mobile phone, the tablet computer, the notebook computer and the like are close to the generated magnetic field, the built-in power receiving coil of the mobile equipment generates induction current, and therefore power can be supplied to the mobile equipment through the small table plate of the wirelessly chargeable seat. This little table of seat is particularly useful for aircraft seat to the passenger can need not the cruise stage that the folding was got up at little table of seat and places electronic equipment such as cell-phone on little table, realizes that equipment charges convenient and fast.

The upper side of the seat tray according to the present invention is marked with a charging induction area, on which the device to be charged is to be placed, and the area of the charging induction area is, for example, 70 × 20 mm. Of course, other suitable sizes of the charge induction area can be selected according to actual needs. If necessary, the charging induction area can be arranged on the whole upper side of the small table board of the seat, so that a plurality of devices to be charged can be charged simultaneously.

In an embodiment, a drive for the power transmission coil is arranged in the seat cell plate according to the invention. When the mobile phone is placed on the small table plate, the placing position of the mobile phone is automatically detected through the detection system, the power transmission coil is moved to the placing position through the driving device, the positions of the power transmission coil and the power receiving coil are consistent, namely, the power transmission coil and the power receiving coil are aligned with each other without deviation, and therefore the charging efficiency is improved.

The utility model discloses still relate to the seat that has the little table of seat that can wirelessly charge.

The seat tablet according to the utility model is fixedly or movably arranged at the part of the seat. If the tablet is movably mounted at a component of the seat, for example by hinging, the tablet can be stowed away when it is not needed, thus saving space.

In a preferred embodiment, a seat tablet according to the invention is mounted on the back side of the seat. In the case where the tablet is movably mounted on the back side of the seat, as has heretofore been common in airplanes or high-speed trains, the tablet can be retractably locked on the back side of the seat by the locking means when the tablet is not used or when the use of the seat tablet is not appropriate. Here, "stowing" is understood to mean that the seat flap rests against the back of the seat.

In another preferred embodiment, a seat tablet according to the invention is mounted at the seat side. In the case where the tablet is movably mounted on the seat side portion, a receiving portion for the tablet is provided in the seat side portion. When the small table is not used, the small table is accommodated in the accommodating part. When the tablet is required to be used, for example, when the device to be charged is required to be charged, the tablet can be taken out of the storage section and placed in a substantially flat state in an operating state.

According to the utility model discloses a little table of seat that can wirelessly charge not only can be used to the seat of aircraft, can be used to the seat of train, motor vehicle, boats and ships or other devices moreover.

Drawings

The invention is further explained below with the aid of the attached drawing, in which:

fig. 1 illustrates the working principle of electromagnetic induction wireless charging;

figure 2 schematically illustrates an embodiment of a wirelessly chargeable seat tablet for a seat.

Detailed Description

An embodiment of a wirelessly chargeable seat tablet 6 for a seat 1 is schematically shown in fig. 2.

As can be seen from fig. 2, a wirelessly chargeable seat tablet 6 is mounted on the back side of the seat 1, and the seat tablet is in a use state, i.e. in a substantially flat state. The mobile device 2 being charged is placed on the seat tablet 6, wherein the power receiving coil 3 of the mobile device 2 and the power transmitting coil 5 of the seat tablet 6 are vertically aligned with each other. The magnetic field 4 through the power transmitting coil 5 and the power receiving coil 3 is also schematically shown in fig. 2.
