Description

Sound control luminous wireless charging device

Technical Field

Background

Smart phones and various wearable devices are particularly common electronic products in life at present, and various demands of consumers on communication, biological state monitoring, entertainment and the like can be met through the smart phones and the wearable devices. Devices such as smart phones often need to be charged, and wireless chargers have gradually taken a leading role in the charging field of consumer terminals such as smart phones in recent years because the smart phones can be prevented from being plugged and unplugged during charging.

Most of the wireless charging devices on the market at present comprise a light-emitting device, and the light-emitting device mainly has three functions:

(1) As a status indicator lamp of the wireless charger, a light emitting source of the light emitting device generally adopts a single-color or multi-color LED lamp, and a user can timely grasp the working status of the wireless charger through the light emitting status of the LED lamp, such as charging or full charge of electric quantity.

(2) As a basic decorative lighting unit, there is only a simple lighting function. The light-emitting source is also a single-color or multi-color LED lamp, and the light-emitting state is not used for indicating the working state of the wireless charger, but plays an integral decorative role. The Chinese patent No. 208939627U discloses a luminous wireless charger, which makes the wireless charger in a luminous state by luminous on the surface cover and the side surface, plays a role in decoration and can enable a user to find the wireless charger more conveniently at night.

(3) As a method for marking the position of a wireless charger, for example, a luminous wireless charging structure disclosed in chinese patent application publication CN109672237a is disclosed, which mainly aims to solve the problem of wireless charging alignment by illuminating the exact position of a wireless charging coil.

The light-emitting wireless charger in the prior art basically emits light according to a preset mode by the main control of the wireless charger no matter how the light-emitting device acts, on one hand, the real requirements of users may not be met, for example, the aforesaid Chinese patent No. 208939627U, although the specific position of the wireless charger can be quickly found through light emission, the design of continuous light emission during the night period can cause light pollution to influence sleeping. On the other hand, the luminous wireless chargers lack interaction capability with users in the using process, so that the using experience brought to the users is single and tedious, and the user experience is poor. Based on this, the applicant filed 2021 and obtained chinese patent No. CN216057148U, which proposes a sound control light-emitting wireless charger, which enhances the user experience of the product by receiving the sound of the user to control the light-emitting intensity and sequence of the light-emitting units. However, in this solution, because the number of circuit modules such as the audio signal input unit, the light-emitting communication control unit, and the light-emitting unit is increased compared with the common wireless charger, and these circuit modules and the wireless charging module are all concentrated under the wireless charger surface cover, in order not to affect the basic wireless charging effect, the audio signal input unit, the light-emitting communication control unit, and the light-emitting unit and the wireless charging module adopt a basic tiling manner, which leads to an increase in the size of the wireless charger, that is, the wireless charger with the sound-control light-emitting function in the prior art is difficult to consider the compactness of the structure, and is especially not suitable for the wireless charger for small-size electronic products, such as the wireless charger for charging the smart watch.

The outer contour of the light guiding substrate 600 may generally correspond to the middle frame substrate 300, such as being circular, and two fourth indentations 653 may be located at opposite ends of the diameter of the light guiding substrate 300.

The bottom chassis 17 includes a bottom chassis base 170, fixing posts 172, touch electrode areas 173, bottom chassis positioning posts 174, and touch operation areas 176. The bottom case base 170 may be a circular housing, two fixing columns 172 are disposed at two ends of the diameter of the circular housing, and the two fixing columns 172 correspond to the two fifth notches 672, so that the light guide plate 16 may be relatively fixed in position in the charging tray by clamping the fixing columns 172 in the fifth notches 672. The bottom shell positioning columns 174 correspond to the second positioning grooves 320 of the middle frame, and the bottom shell 17 can be mounted on the middle frame 13 by clamping the bottom shell positioning columns 174 into the second positioning grooves 320, so that the first circuit board 15 and the light guide plate 16 are located between the middle frame 13 and the bottom shell 17, and light emitted by the light emitting unit 552 is transmitted to the bottom shell 17 and the annular wall of the middle frame 13 more uniformly after passing through the light guide plate 16. At least the lower half of the peripheral walls of the bottom case 17 and the middle frame 13 are made of transparent material, so that light can be transmitted to the outside of the charger to be visually recognized by a user. The touch electrode area 173 is located on the inner side of the bottom case 17 (also on the inner side of the bottom case substrate 170), the touch electrode area 173 includes touch electrodes (not shown), and the touch connection member 553 passes through a corresponding fourth notch 653 on the light guide plate 16 to be connected to the touch electrodes of the touch electrode area 173. The touch operation area 176 is located at the outer side of the bottom chassis 17 (i.e., the lower surface of the charging tray case) and corresponds to the touch electrode area 173. By performing a touch operation in the touch operation area 176, the touch electrode of the touch electrode area 173 inside the corresponding position is subjected to a change in charge due to the influence of a finger, and is further sensed by the touch module connected thereto to output a touch signal, and the light emitting unit 552 emits light or changes the light emitting state in response to the touch signal or in response to the touch signal and the voice control signal.

As one example, the touch operation area 176 is recessed toward the inside of the bottom chassis 17, and the inwardly recessed touch operation area 176 is lower than other areas on the outside of the bottom chassis base 170, so the touch operation area 176 is not easily touched by mistake.

As one example, three touch signals, long press, single click, and double click, respectively, may be identified by the touch module. The long press can function as a switch light, and the light emitting unit 552 can be turned off by long press of the touch operation area 176 when the user does not want the light. The mode of switching the light efficiency can be controlled by double clicking the touch operation area 176, and the light efficiency gear in the current mode can be switched by clicking.

The modes of light effect may include a rhythmic mode, an indicator light mode, a night light/breathing light mode. The voice rhythm mode is a voice control mode, in which the voice control signal output by the voice control module 555 can be effectively transmitted to the light emitting unit 552, and the interactivity and the interestingness of the wireless charging device can be increased by controlling the light emitting effect through sound. The indication lamp mode refers to an operation state in which the light emitting unit 552 is used to indicate wireless charging. In the night light/breathing light mode, the light emitting unit 552 does not receive the control of the sound control signal, and the light emitting unit 552 is turned on/off (breathing state) according to a certain rule under the control of the main control module.

Different lighting effects can also be achieved by clicking the touch operation area 176 in different modes. For example, in night light mode, different light colors or light brightness levels can be switched by clicking, changing color or level once per click. Also, for example, in the rhythmic mode, different light effects, that is, different colors or brightness levels in this mode, may be switched by clicking the touch operation area 176.

The light emitting unit 552 is controlled by combining the wireless charging device with the voice control and the touch control, so that the requirements of users in different scenes can be met, for example, voice control interaction is not needed when the users sleep, and the users only need to control the night lamp in a night lamp mode. And in other cases, the voice control system can be flexibly switched to a voice rhythm mode, so that the voice control of the light effect is realized, and the playability of the product is improved. The capacity of the lamp effect scheme that this scheme fully plays present hardware, on the luminous basis of acoustic control has further improved same product can hold, and the user of being convenient for can carry out nimble adjustment according to different demands to very big promotion wireless charger's interactivity, playability and user experience.
