Description

Touchpad structure capable of providing wireless charging source

This creation is a touchpad structure that can provide a wireless charging source, especially a structure with both touchpad and wireless charging functions.

In recent years, due to the advancement of technology, various electronic products have continued to introduce new ones, especially in terms of charging technology. The 3C products of major brands have also been added to the design of wireless charging one after another. Users only need to use wireless charging stand or wireless charging slide The mouse pad can wirelessly charge devices such as smart phones, smart watches, and wireless charging mice in daily life.

However, regardless of the wireless charging dock or wireless charging mouse pad, it must be connected to a power outlet or computer through a USB cable, which is quite inconvenient to use; therefore, how to integrate wireless charging into common electronic products in life , The focus of the industry’s main research and development.

In view of this, the creator of this case used his years of experience in relevant design practices to actively research and improve, and after many physical sample production and testing, he specifically improved the above-mentioned shortcomings of the conventional knowledge and finally completed the creation.

In order to overcome the above shortcomings, this creation provides a wireless charging touch panel structure. The wireless charging module is placed under the capacitive touch panel, so that the device placed on the top surface of the capacitive touch panel can reach Wireless charging.

This creation is a touch panel structure that can provide a wireless charging source, which includes: a capacitive touch panel connected to a power supply device; a wireless charging module, which is set on the capacitive touch panel Below, and the wireless charging module has a control unit and a coil unit. The control unit is used to convert the power of the power supply device into a charging electromagnetic force with a specific power and output by the coil unit; When the charging device is located on the top surface of the capacitive touch panel and forms an inductive coupling with the wireless charging module, the control unit converts the electric power into a charging electromagnetic force with a specific power and is output by the coil unit for the wireless charging After the equipment is received, it is converted into electricity and stored.

The following is a detailed description with specific examples and drawings, so that the review committee can have a better understanding of the technical features of this creation.

As shown in FIGS. 1 to 4, it is a preferred embodiment of the touch panel structure of the present invention that can provide a wireless charging source, which includes: a capacitive touch panel 10 and a wireless charging module 20.

Regarding the capacitive touchpad 10 (Touchpad), it is connected to a power supply device 40. The power supply device 40 can be a utility power, a computer or a notebook computer. In this embodiment, the power supply device 40 is A notebook computer, and the capacitive touch panel 10 is assembled on a notebook computer (that is, the basic configuration of a general commercially available notebook computer); of course, in practice, the capacitive touch panel 10 can also be assembled Set up on related electronic products or other computer peripherals.

The top surface of the capacitive touch panel 10 is a touch area. When a user touches a fixed point position of the touch area with a finger, the touched position will generate a signal of capacitive sensing potential change, and the The capacitive touch panel 10 converts this signal into a two-dimensional coordinate signal.

As shown in FIG. 2, the wireless charging module 20 is assembled under the capacitive touch panel 10 and receives power from the power supply device 40; the wireless charging module 20 has a control unit 21 and a coil Unit 22, the control unit 21 is a printed circuit board (PCB, Printed circuit board), used to convert the power of the power supply device 40 into a charging electromagnetic force with a specific power and output by the coil unit 22, so that the capacitor The top surface of the touchpad 10 generates a charging electromagnetic force of a specific power.

In this embodiment, the control unit 21 is connected to the coil unit 22, and the coil unit 22 is arranged above the control unit 21, so that the coil unit 22 is adjacent to the capacitive touch panel 10 and has a relatively high Excellent charging electromagnetic force transmission effect.

When a wireless charging device 60 is located on the top surface of the capacitive touch panel 10 and forms an inductive coupling with the wireless charging module 20, the control unit 21 converts the electric power into a charging electromagnetic force with a specific power and is used by the coil The output of the unit 22 is received by the wireless charging device 60 and converted into electricity and stored.

The wireless charging device 60 can be a wireless charging mobile phone, a wireless charging mouse or a wireless charging watch and other electronic products. When the wireless charging device 60 receives the charging electromagnetic force output by the coil unit 22, it is converted into electric power and Stored in the internal power storage device.

In more detail, through the combination of the capacitive touch panel 10 and the wireless charging module 20, this creation can have the following two usage modes:

[1] General touch mode. When the top surface of the capacitive touch panel 10 is not provided with the wireless charging device 60, the capacitive touch panel 10 is only used as a general touch panel, and the wireless charging module 20 does not operate.

[2] Wireless charging mode. When a wireless charging device 60 such as a wireless charging mobile phone, a wireless charging mouse or a wireless charging watch is placed on the top surface of the capacitive touch panel 10, the control unit 21 controls the coil unit 22 to start, so that the wireless charging is possible The device 60 receives the charging electromagnetic force output by the coil unit 22, converts it into electric power and stores it in an internal power storage device.

That is to say, the original touch function of the capacitive touch pad 10 assembled on the notebook computer is not affected, and when the capacitive touch pad 10 is not needed (for example: notebook type The mouse is connected to the computer or is not used temporarily), the wireless charging device 60 can be placed on the top surface of the capacitive touch pad 10 to achieve the effect of wireless charging.

As shown in FIG. 4, it is a schematic diagram of the use state of the creative touchpad and wireless charging device. As can be seen from FIG. 4, the capacitive touchpad 10 is assembled on a notebook computer, and the wireless charging The device 60 is a wireless charging mobile phone and is placed on the capacitive touch panel 10, so that the user can wirelessly charge the wireless charging mobile phone while using the notebook computer.

To sum up, in this creation, the control unit 21 and the coil unit 22 are assembled under the capacitive touch panel 10, and the coil unit 22 is adjacent to the capacitive touch panel 10, and through the The thin volume of the capacitive touch panel 10 enables the coil unit 22 of the wireless charging module 20 to have a better charging electromagnetic force output effect, thereby achieving the purpose of wireless charging.

In addition, it can be seen from the above-mentioned embodiments that the wireless charging module 20 is placed under the touchpad of the notebook computer, and the flat top surface of the touchpad itself is used to hold the wireless charging mouse, wireless The surface area of rechargeable watches and wireless rechargeable mobile phones enables wireless charging technology to be integrated into notebook computers and does not affect the original functions of the notebook’s touchpad. Therefore, the design of this creation can effectively solve the problem of the past Wireless charging requires additional preparation of the disadvantages of wireless charging stand.

Based on the above detailed description, those who are familiar with this technique can understand that this creation can indeed achieve the aforementioned purpose, and that it has actually complied with the provisions of the Patent Law, and filed a new patent application.
