technical field

The invention relates to a three-dimensional glass back cover of a hand-held device with a power supply device, which has the effect of increasing the battery capacity of the hand-held device to greatly improve the endurance of the battery of the hand-held device.

Background technique

In recent years, with the rapid development of electronic technology, the portable electronic products that are carried around are being introduced even more, not only mobile phones, personal digital assistants, but also MP3 players, tablet computers, notebook computers, etc., almost can be said to be numerous At the same time, not only the number of portable devices has increased, but also because the functions are becoming more powerful and the display screens are getting larger and larger, the power consumption will naturally increase exponentially. Although battery technology is advancing rapidly, it is still difficult to catch up with the increase in power consumption required by electronic products. Therefore, generally speaking, the battery life of electronic products either increases slowly or does not increase but decreases; for terminal users , It is naturally quite inconvenient to use. Most of the above-mentioned hand-held devices use rechargeable batteries such as nickel-hydrogen batteries or lithium batteries for the power required for use. Currently, the most commonly used lithium batteries are all hard shells because of their structure, and have a considerable Thickness (about 5-10mm). And this kind of rechargeable battery is installed in the chamber that is provided with in the hand-held device. China Taiwan Patent No. M494464 "Multifunctional Mobile Phone Back Cover" patent, which is installed on a mobile phone main body, the mobile phone main body has at least one application mode, and the multifunctional mobile phone back cover includes: a back cover main body; a physical button, set At least one functional operation mode is provided on the back cover main body; a battery is arranged in the back cover main body and is electrically connected to the physical button to provide the operating power of the physical button; A power indicator light is arranged on the main body of the back cover to display a power signal according to the power of the battery; a micro-main controller is arranged in the main body of the back cover and is electrically connected to the physical button. pairing the application mode of the mobile phone body according to the functional operation mode of the physical button, and correspondingly outputting a control signal according to the functional operation mode; and A power microcontroller, electrically connected to the battery and the power indicator light, the power microcontroller monitors the battery power and controls the power indicator light to display the power signal, and controls the battery to provide the operating power for the physical button (Refer to the patent announcement data on January 21, 2015). Bulletin number M508116 "Glass back cover structure with wireless charging function", which includes: a three-dimensional glass substrate, the three-dimensional glass substrate has a main body glass part and a surrounding glass part bent upwards and extended from the periphery of the main body glass part Shaped glass part, wherein the main body glass part is surrounded by the surrounding glass part; a wireless charging receiving coil, the wireless charging receiving coil is arranged on the three-dimensional glass substrate, wherein the wireless charging receiving coil has a A first conductive contact end and a second conductive contact end corresponding to the first conductive contact end; and a magnetic field absorption shield, the magnetic field absorption shield is arranged on the three-dimensional glass substrate to cover the wireless charging The receiving coil, wherein the first conductive contact end and the second conductive contact end of the wireless charging receiving coil are both exposed from the magnetic field absorbing shield; wherein the three-dimensional glass substrate is set on a portable the back of the portable electronic device, and the first conductive contact end and the second conductive contact end of the wireless charging receiving coil electrically contact a positive contact and a negative contact of the portable electronic device respectively; wherein , the portable electronic device is placed on a wireless charging board with a wireless charging transmitting coil, and the electromagnetic field generated by the wireless charging transmitting coil passes through the three-dimensional glass substrate and is wirelessly transmitted to the Wireless charging receiving coil (refer to the patent announcement data on September 1, 2015). It can be seen that in the prior art, the battery inside the handheld device is charged (or wirelessly charged) by adding a leather case, card holder, protective cover, back cover, etc. on the outside of the handheld device, and there is still room for improvement.

Furthermore, due to the advancement of technology and the needs of life, portable electronic devices are becoming more and more popular. Therefore, the appearance of portable electronic devices is designed towards the trend of lightness, thinness, shortness and smallness, so as to be convenient for people to carry. Plastic materials, in particular, are widely used due to their high ductility. Due to the relationship between material properties, under the trend of light, thin, short, small and changeable shapes, plastic materials and metal materials are widely used in curved surface shapes, while glass materials are only widely used in flat shapes. However, the casings of existing portable electronic devices are made of plastic or metal, which will still be worn or even damaged after being used for a period of time. With the rise of environmental awareness and the protection of the earth, metal materials and glass materials are gradually being used. With the thinning of the design, when the thickness of the product becomes thinner and thinner, the plastic material and metal material will lose their strength and be easily deformed and damaged, and can be replaced by glass. Therefore, three-dimensional or curved glass has been gradually applied to glass casings of electronic products. How to use the characteristics of three-dimensional glass to improve the existing technology is to charge the battery (or wireless charging) inside the handheld device by adding leather sleeves, card sleeves, protective sleeves, back covers, etc. to the outside of the handheld device. Difficulties to be overcome urgently in the technical field.

Contents of the invention

Aiming at the shortcomings of the prior art, the main purpose of the present invention is to provide a three-dimensional glass back cover of a handheld device with a power supply device.

The invention provides a three-dimensional glass back cover of a handheld device with a power supply device, which is combined and sealed on the back of the handheld device. The three-dimensional glass back cover has a main body and a curved portion formed by bending the periphery of the main body upward.
