Description

Technical Field

[0001] The utility model relates to the technology of wireless charging field, in particular to a wireless charging device. Background Art

[0002] A wireless charger is a device that uses the principle of electromagnetic induction for charging. It is equipped with a coil at both the transmitting and receiving ends. The transmitting-end coil emits electromagnetic signals to the outside under the action of electricity, and the receiving-end coil receives the electromagnetic signals and converts them into electric current, so as to achieve the purpose of wireless charging. Wireless charging technology is a special power supply method. It does not require a power cord and relies on the propagation of electromagnetic waves, and then converts the electromagnetic wave energy into electric energy to finally realize wireless charging.

[0003] The existing wireless charging devices only charge specific terminals wirelessly and cannot match multiple mobile terminals. At present, more and more intelligent wrist-worn devices have converted the original wired charging method or contact charging method into a wireless charging method. In the wireless charging method, a wireless charging base is equipped for the intelligent wrist-worn device. When charging each time, the user can directly place intelligent wrist-worn devices such as watches and bracelets on the wireless charging base to achieve charging. Specifically, it realizes wireless charging through the charging coils arranged in the intelligent wrist-worn device and the wireless charging base. However, since the relative position of the intelligent wrist-worn device placed on the wireless charging base each time is not fixed, there is often a situation where the charging coil in the wireless charging base and the charging coil in the intelligent wrist-worn device cannot completely coincide in the vertical direction, resulting in a reduction in the charging efficiency of the intelligent wrist-worn device, too long charging time, and large heat generation, thus affecting the user experience. Based on this, it is necessary to study a new technical solution to improve and innovate the current wireless charging device. Summary of the Utility Model

[0024] In order to make the purpose, technical solutions and advantages of the present utility model clearer, the following further details the present utility model in conjunction with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model. In addition, the technical features involved in the various embodiments of the present utility model described below can be combined with each other as long as they do not conflict with each other.

[0025] The wireless charging device of the present application includes a wireless charging base 100, and the wireless charging base 100 has a plurality of charging plugs 50 of different types. The wireless charging base 100 has a first housing 10. In the present application, the first housing 10 is a square housing or a circular housing, and the shape of the first housing 10 is not limited in the present application.

[0026] A fixing base 20, a magnet cavity 70 and a wireless charging module are arranged in the first housing 10. The wireless charging module includes a magnet 30 and a charging coil 40. The charging coil 40 is installed on the fixing base 20, and the magnet 30 is installed in the magnet cavity 70. The charging plug 50 is electrically connected to the wireless charging module.

[0027] In the present application, the first housing 10 includes a front shell 11 and a rear shell 12. Clasps are arranged on the inner wall of the front shell 11, and a plurality of card slots are arranged on the rear shell 12. A part of the rear shell 12 extends into the front shell 11 so that the clasps are engaged with the card slots, thereby forming the first housing 10 with a receiving function. The wireless charging module is installed on the rear shell 12, and different types of charging plugs 50 are electrically connected to the charging coil 40.

[0028] The front shell 11 is provided with a wireless charging area 80, which serves as a standard charging position for the wireless charging device. The size of the wireless charging area 80 is adapted to the size of the charging coil 40 of the wireless charging module, and the position of the wireless charging area 80 corresponds to the position of the charging coil 40. The front shell 11 is also provided with a wireless charging socket 13.

[0029] In this application, an anti-slip pad is provided on the outer surface of the rear shell 12 of the first housing 10. Specifically, the charging coil 40 wirelessly charges the terminal device, and at the same time, the magnet 30 can generate a certain suction force on the terminal device through the anti-slip pad to prevent it from detaching from the anti-slip pad. The terminal device can be a mobile terminal, headphones, a smart watch, etc. In this application, the terminal device is a mobile terminal, such as a mobile phone.

[0030] The wireless charging base 100 also has a second housing 60, which is used to be clamped on the charging plug 50 to safely protect the charging plug 50. See Figure 2 And Figure 3 , a charging plug 50 is installed at each of the head and tail of the wireless charging base 100, and each charging plug 50 is clamped with a second housing 60.

[0031] The wireless charging device of this application is provided with multiple different types of chargers on the wireless charging base 100, which are convenient for going out and can be adapted to different jacks. It can also be directly plugged into a mobile phone, a tablet computer or a laptop for use, making it more convenient, effectively increasing the charging scenarios, and eliminating the need to carry an additional charging cable.

[0032] In the wireless charging mode, when the user charges each time, the smart wrist-worn device can be directly placed on the wireless charging area 80 to achieve charging, which is specifically realized through the charging coils 40 provided in the smart wrist-worn device and the wireless charging base 100. However, since the relative position of the smart wrist-worn device placed on the wireless charging base 100 is not fixed each time, there is often a situation where the charging coil 40 in the wireless charging base 100 and the charging coil 40 in the smart wrist-worn device cannot completely coincide in the vertical direction, resulting in a reduction in the charging efficiency of the smart wrist-worn device, an excessive charging time, and a large amount of heat generation, thus affecting the user experience.

[0033] The wireless charging device of this application can be used as a wireless charging base 100 for the wrist-worn device to give a charging deviation prompt when the wrist-worn device deviates from the standard charging position, so as to remind the user to adjust the charging position of the wrist-worn device, thereby avoiding the charging deviation of the wrist-worn device.

[0034] The wireless charging base 100 of the present application is configured with a detection module, a main control module, and a prompting module. The detection module is used to detect the position-related information of the wrist-worn device placed on the wireless charging base 100, and the main control module is used to determine whether the wrist-worn device is placed at the specified charging position of the wireless charging base 100 according to the position-related information; if not, the prompting module is controlled to give a charging deviation prompt.

[0035] Specifically, since the volume of the wrist-worn device (such as a smart watch) itself is small, the charging coil 40 provided inside the wrist-worn device is also small, resulting in a significant impact on the charging efficiency of the wrist-worn device even with a slight movement. This makes the placement position of the wrist-worn device on the wireless charging base 100 require a high standard. Therefore, it is very necessary to design a wireless charging base 100 with a deviation detection and reminder function. The wireless charging base 100 of the present application with a deviation detection and reminder function includes a prompting module, a detection module, and a main control module (the main control function can be implemented by a CPU (Central Processing Unit)), and the main control module is installed on the circuit board 90 of the wireless charging base 100 of the present application.

[0036] Its working principle is as follows: After the wrist-worn device is placed on the wireless charging base 100, the detection module can detect the position-related information of the wrist-worn device placed on the wireless charging base 100 and send the position-related information of the wrist-worn device to the main control module. After receiving the position-related information of the wrist-worn device, the main control module can determine the placement position of the wrist-worn device on the wireless charging base 100 according to the position-related information of the wrist-worn device to judge whether the wrist-worn device is placed at the specified charging position of the wireless charging base 100. If the wrist-worn device is placed at the specified charging position of the wireless charging base 100, it means that the charging of the wrist-worn device is not deviated, and there is no need to adjust the charging position of the wrist-worn device. At this time, the prompting module can be controlled to give a charging non-deviation prompt to inform the user that the charging of the wrist-worn device is not deviated, or the prompting module can not be controlled to perform a prompting operation; if the wrist-worn device is not placed at the specified charging position of the wireless charging base 100, it means that the charging of the wrist-worn device is deviated and the charging position of the wrist-worn device needs to be adjusted, then the prompting module is controlled to give a charging deviation prompt to remind the user to adjust the charging position of the wrist-worn device, so as to avoid charging deviation of the wrist-worn device.

[0037] The magnet in the wrist-worn device of the present application is located at the central position inside the charging coil 40 of the wrist-worn device. It should be noted that the shape of the magnet is not limited to a cylinder.

[0038] The wrist-worn device of the present application is provided with a magnet inside, so the relative position information between the wireless charging base 100 and the wrist-worn device can be determined by detecting the magnetic field situation on the wireless charging base 100. Based on this, the detection module in the wireless charging base 100 includes a plurality of Hall devices, and each Hall device is used to detect the magnetic field polarity and magnetic field magnitude at its own position.

[0039] The plurality of Hall devices include: a first Hall device located at the central position inside the charging coil 40 of the wireless charging base 100; a plurality of second Hall devices located outside the charging coil 40; wherein, the distances between the plurality of second Hall devices and the first Hall device are the same, and the positions where the plurality of second Hall devices are located are connected in sequence to form a regular polygon;

[0040] Specifically, the main control module is used to determine that the wrist-worn device is placed in the standard charging position if the magnetic field polarities detected by the first Hall device and each second Hall device are all different, and the magnetic field intensity detected by the first Hall device is the largest and the magnetic field intensities detected by the plurality of second Hall devices are consistent; if the magnetic field polarities detected by all Hall devices are the same, and the magnetic field intensity detected by the first Hall device is the largest and the magnetic field intensities detected by the plurality of second Hall devices are inconsistent, it is determined that the charging of the wrist-worn device is slightly misaligned; if there is a target Hall device among the second Hall devices whose detected magnetic field polarity is different from that of the other Hall devices, and the magnetic field intensity detected by the target Hall device is the largest and the magnetic field intensities detected by the other Hall devices are inconsistent, it is determined that the charging of the wrist-worn device is severely misaligned.

[0041] Specifically, the main control module is used to determine the relative position information between the wireless charging base 100 and the wrist-worn device according to the magnetic field polarity and magnetic field magnitude detected by the plurality of Hall devices. The main control module determines the degree of charging misalignment of the wrist-worn device according to the detection result of the detection module, and controls the prompt module to give corresponding charging misalignment indications according to the degree of charging misalignment of the wrist-worn device. For example, the prompt module includes three LED (light-emitting diode) indicator lights: a red light, a yellow light, and a green light. Specifically, the main control module is used to control the green light to turn on if it is detected that the charging of the wrist-worn device is not misaligned; control the yellow light to turn on if it is detected that the charging of the wrist-worn device is slightly misaligned; control the red light to turn on if it is detected that the charging of the wrist-worn device is severely misaligned.

[0042] Those skilled in the art can easily understand that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
