[0036] Example 1
[0037] Combination Figure 1 , Figure 2 As shown, this embodiment provides a wireless charging device, including a housing 100 , a wireless charging receiving module 200 , a charging plug 300 , and a telescopic assembly 400 .
[0038] The shell 100 is wrapped around the outside of the electrical device; the wireless charging receiving module 200 is arranged on the shell 100; the charging plug 300 is arranged on the shell 100, the charging plug 300 is electrically connected to the wireless charging receiving module 200, and the charging plug 300 is used to be inserted into the charging socket of the electrical device; the telescopic component 400 is arranged on the shell 100, and the charging plug 300 is cooperatively connected with the telescopic component 400; the telescopic component 400 can drive the charging plug 300 to move in a direction close to or away from the charging socket of the electrical device.
[0039] When the wireless charging device provided in this embodiment is used, the shell 100 is first wrapped around the outside of the electrical device, and then the charging plug 300 is aligned with the charging socket of the electrical device and inserted. At this time, the wireless charging receiving module 200 on the shell 100 can be electrically connected to the electrical device through the charging plug 300, so that the shell 100 in this embodiment can provide protection for the electrical device, and can also electrically connect the electrical device to the wireless charging receiving module 200 on the shell 100, so that the electrical device supports the wireless charging function. When the electrical device needs to be charged or powered on, it only needs to be placed near the corresponding wireless charging device to charge or power on. The operation is convenient, and the leakage of the power-carrying wire 423 of the electrical device can be reduced. There is no need to manage the wires, which can greatly improve the charging safety of the electrical device.
[0040] When the electric device needs to use the charging interface for data transmission or use the charging interface for wired charging, it is only necessary to drive the charging plug 300 to move away from the charging interface through the telescopic component 400, and there is no need to remove the shell 100 from the electric device as a whole. The charging plug 300 can be removed from the charging socket without affecting the protection function provided by the shell 100 for the electric device; after the charging plug 300 is removed from the charging socket, the electric device can use the charging interface to connect an external device for data transmission or use the charging interface for wired charging; the above-mentioned entire use process can be completed without removing the shell 100 from the electric device as a whole, and the operation is simple. In addition, the protection provided by the shell 100 for the electric device can effectively prevent the electric device from being damaged by bumps or other influences, ensuring that this embodiment provides a reliable protection function for the electric device.
[0041] In some embodiments, the wireless charging receiving module 200 includes an induction coil 210 and a control chip 220, the induction coil 210 is electrically connected to the control chip 220, and the control chip 220 is electrically connected to the charging plug 300; specifically, when using the wireless charging receiving module 200 to charge an electrical device, the induction coil 210 is first placed close to a wireless charging device such as a charging stand. Based on the principle of electromagnetic induction, when the alternating electromagnetic field generated by the transmitting end (charging stand) is transmitted through the air to the induction coil 210 on the wireless charging receiving module 200, the free electrons in the induction coil 210 generate eddy currents due to the alternation of the electromagnetic field, which are then converted into directional currents, thereby charging the batteries in the electrical device.
[0042] The control chip 220 of the wireless charging receiving module 200 is the brain of the system, responsible for managing the entire wireless charging process to ensure efficient and safe power reception and conversion. That is, the control chip 220 needs to be compatible with mainstream wireless charging standards, such as the Qi standard (developed by WPC, the Wireless Power Consortium). For example, FS9401 is a control chip 220 that supports 1-5W wireless charging reception and is compatible with the Qi protocol, while other chips such as IP6808 support higher power (such as 5-15W) wireless charging and are compatible with the latest standards such as WPC Qi v1.2.4, suitable for a wider range of devices. By selecting different models of the control chip 220, the wireless charging receiving module 200 can be adapted to more wireless charging devices; the control chip 220 is driven by a built-in PWM (pulse width modulation) to intelligently adjust the input wireless energy to match the needs of the receiving end and maintain the safety of battery charging. It also needs to monitor the charging status to ensure that it is not overcharged or overheated. In order to reduce the additional energy loss during the wireless charging process, the control chip 220 itself needs to have a low power consumption design, such as low static current, to ensure the energy efficiency of the entire system.
[0043] In some embodiments, the shell 100 includes a shell bottom plate 110 and multiple side plates 120, and the side plates 120 are arranged around the bottom plate 110 to provide protection for the side walls or back cover of the electrical equipment respectively. By using the bottom plate 110 and the side plates 120 to provide protection for the electrical equipment in multiple directions, the comprehensiveness of the protection provided by this embodiment to the electrical equipment can be greatly improved.
[0044] In some embodiments, the bottom plate 110 is evenly distributed with buffer ribs 111 on the end surface close to the electrical equipment, so that when the electrical equipment falls or bumps, the buffer ribs 111 can provide effective buffering and shock absorption effect, effectively reduce the probability of damage to the electrical equipment, and improve the safety of the electrical equipment.
[0045] In some embodiments, the buffer ribs 111 are configured to be ring-shaped with the wireless charging receiving module 200 as the center, and are spread outward at equal intervals, so that the buffer ribs 111 support the rear shell of the electrical device more evenly and stably.
[0046] In some embodiments, the buffer rib 111 also includes transverse ribs, which are arranged radially along the annular buffer rib 111, and a plurality of transverse ribs are evenly distributed relative to the center of the annular buffer rib 111. The transverse ribs are staggered with the annular buffer rib 111 to further improve its own structural strength. Of course, in other embodiments of the present invention, the buffer rib 111 can also be laid in other shapes or structures.
[0047] In some embodiments, the shell 100 is made of silicone material as a whole, which can effectively improve the buffering performance and the protection capability provided for the electrical equipment on the one hand, and can improve the user's grip feel on the other hand, while increasing the friction when holding the shell 100, thereby reducing the probability of the electrical equipment slipping out of the user's hand; of course, in other embodiments of the present invention, the shell 100 can also be made of other materials.
[0048] In some embodiments, a plurality of installation slots 122 are provided on the side panel 120, dividing the side panel 120 into a plurality of parts. When the shell 100 is installed on an electrical device, the side panel 120 can be driven to deflect in a direction away from the electrical device, and then the electrical device is placed in the shell 100. The side panel 120 is then loosened, so that each side panel 120 can be clamped closely to the side wall of the electrical device, which is convenient to operate and install.
[0049] In some embodiments, the shell 100 is provided with button holes 121 and function holes 112 corresponding to the electrical devices. The button holes 121 include holes reserved for positions such as the power button and volume button of a mobile phone, and the function holes 112 include holes reserved for positions such as the camera and speaker on a mobile phone; so that when the shell 100 covers and protects the electrical devices, it does not affect the normal use of the button operations and functions of the electrical devices.
[0050] In some embodiments, a middle button is embedded in the button hole 121. When the user needs to press the corresponding function key, the user directly presses the middle button in the button hole 121 to press the function key through the middle button. On the one hand, the user does not need to go deep into the button hole 121 to press the function key, which saves more effort and is more convenient to operate. On the other hand, the shell 100 can provide protection for the buttons on the electrical equipment and reduce the probability of button damage.
[0051] In some embodiments, a transparent protective plate is embedded in the functional hole 112 to provide comprehensive protection for the functional components on the electrical equipment without affecting the normal use of the functional components, thereby reducing the probability of damage to the relevant functional components.
[0052] like Figure 3As shown, in some embodiments, the telescopic assembly 400 includes a telescopic seat 410 and a telescopic member 420. The telescopic seat 410 is arranged on the shell 100. A telescopic groove 411 is provided in the telescopic seat 410. The telescopic member 420 is inserted into the telescopic groove 411. The telescopic member 420 is fixedly connected to the charging plug 300. The telescopic groove 411 can provide directional guidance for the telescopic movement of the telescopic member 420. The telescopic movement of the telescopic member 420 can control the telescopic clutch of the charging plug 300 and the charging socket of the electrical device, which is convenient and simple to operate. Of course, in other embodiments of the utility model, the telescopic assembly 400 can also control the telescopic movement of the charging plug 300 by setting other structures.
[0053] In some embodiments, a telescopic rod 421 is provided at the end of the telescopic member 420 away from the charging plug 300, and a limit plate 422 is provided at the end of the telescopic rod 421 away from the telescopic member 420. A limit step 412 corresponding to the limit plate 422 is provided in the telescopic groove 411, and the limit step 412 is used to limit the movement distance of the limit plate 422 in the telescopic groove 411, thereby limiting the telescopic movement distance of the charging plug 300 driven by the telescopic member 420, thereby preventing the telescopic member 420 from driving the charging plug 300 to telescopically move away from the shell 100 and disconnecting from the wireless charging receiving module 200, thereby preventing damage, thereby improving the reliability of the use of this embodiment.
[0054] In some embodiments, the wireless charging device also includes an elastic member 424, which abuts between the limit plate 422 and the limit step 412; in the absence of external force, the limit plate 422 and the limit step 412 are kept apart by the elastic pressure of the elastic member 424, so that the charging plug 300 and the shell 100 are in a pre-tightened state, thereby preventing the charging plug 300 from shaking or bumping due to external influences when it is not inserted into the charging interface of the electrical device, thereby reducing the probability of damage to the charging plug 300.
[0055] In some embodiments, the elastic member 424 is a spring, which has the advantages of simple structure and reliable provision of preload force. Of course, in other embodiments of the present invention, the elastic member 424 may also be a structure such as an elastic sheet.
[0056] In some embodiments, the spring is sleeved on the telescopic rod 421 to prevent the spring from bending and failing when the spring is compressed, thereby ensuring the reliability of the spring.
