[0001] This utility model relates to the field of wireless power supply device technology, and in particular to a wireless charger. Background Technology

[0002] With more and more mobile phones equipped with wireless charging, charging has become increasingly convenient. However, due to the different sizes of different brands of mobile phones, the position of the wireless charging receiving coil inside the phone varies considerably, meaning that only the wireless charger that comes standard with the corresponding phone model can be used for charging. Using wireless chargers of different models can cause the transmitting coil on the wireless charger and the receiving coil on the phone to not be perfectly aligned, resulting in either poor charging efficiency and excessive heat generation, or failure to charge at all.

[0003] Therefore, to ensure wireless chargers are compatible with different brands of mobile phones, different manufacturers have adopted different design philosophies, but these different philosophies produce varying results. Therefore, this utility model proposes an improved wireless charger design to enhance its compatibility. Utility Model Content

[0036] To make the technical problem to be solved, the technical solution, and the beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model. Therefore, a feature pointed out in this specification is used to describe one feature of one embodiment of the present utility model, and does not imply that every embodiment of the present utility model must have the described feature. Furthermore, it should be noted that this specification describes many features. Although certain features may be combined to illustrate possible system designs, these features may also be used in other combinations not explicitly stated. Therefore, unless otherwise stated, the described combinations are not intended to be limiting.

[0037] The principle and structure of this utility model will be described in detail below with reference to the accompanying drawings and embodiments.

[0038] Existing wireless chargers are not compatible with different brands of mobile phones because different brands of mobile phones have different sizes and the positions of the wireless charging receiving coil inside the phone vary greatly. This means that only the wireless charger that comes standard with the corresponding phone model can be used for charging. If the same model of wireless charger is used to wirelessly charge different brands of mobile phones, the transmitting coil on the wireless charger and the receiving coil on the phone will not be fully aligned, resulting in either poor charging efficiency and severe overheating, or failure to charge.

[0039] Therefore, to solve the above problems, in one embodiment, refer to the appendix. Figure 1-2 This utility model proposes a wireless charger, comprising:

[0040] A base 10, on which a support frame 20 is provided at an incline or vertically, and an active space 211 is formed inside the support frame 20 along its length direction, and a slide 212 communicating with the active space 211 is provided on the back side of the support frame 20 along its length direction.

[0041] A coil adjustment base 30, one end of which is slidably connected to the slide rail 212, and the other end of which extends into the active space 211 and is connected to a wireless charging transmitting coil 40.

[0042] An adjusting screw 50 is provided on the back of the support frame 20 and movably passes through one end of the coil adjusting seat 30;

[0043] Rotating the adjusting screw 50 causes the coil adjusting seat 30 to drive the wireless charging transmitting coil 40 to slide along the axis of the adjusting screw 50 on the slide rail 212.

[0044] It should be noted that the beginning of the adjusting screw 50 is also provided with a knob 511, so that the user can rotate the adjusting screw 50 by rotating the knob 511, thereby adjusting the position of the wireless charging transmitting coil 40; of course, the knob 511 usually has an easy-to-grip shape and size to ensure that the user can apply force comfortably and effectively when rotating.

[0045] Furthermore, a panel 216 is provided on the front of the support frame 20 corresponding to the active space 211. The panel 216 can be opened and closed relative to the active space 211. When the panel 216 is opened relative to the active space 211, the coil adjustment seat 30 located in the active space 211 can be exposed for maintenance or inspection of the wireless charging transmitting coil 40.

[0046] In this way, when a user's mobile phone needs to be wirelessly charged, the phone needs to be placed firmly against the front of the support frame 20. Then, depending on the position difference of the wireless receiving coil of different brands of mobile phones, the user rotates the adjusting screw 50, so that the thread on the adjusting screw 50 interacts with the sliding surface of one end of the coil adjusting seat 30. This interaction causes the coil adjusting seat 30 to slide along the axis of the adjusting screw 50 on the slide rail 212, thereby adjusting the height position of the wireless charging transmitting coil 40 on the support frame 20. This improves the compatibility of the wireless charger, ensuring that the wireless charging transmitting coil 40 on the wireless charger can correctly correspond to the receiving coil on different brands of mobile phones, thus ensuring the charging efficiency of the mobile phone. Moreover, the wireless charger proposed in this embodiment only needs to set one wireless charging transmitting coil 40 to meet the usage requirements, without the need to set multiple wireless charging transmitting coils 40, thereby reducing the production cost of the wireless charger.

[0047] Of course, the adjusting screw 50 proposed in this embodiment has a fine-tuning function, which can achieve a smaller adjustment of the coil adjusting seat 30 by a small rotation, so that the wireless charging transmitting coil 40 on the wireless charger can better and correctly correspond to the receiving coil on mobile phones of different brands.

[0048] In one embodiment, refer to Appendix Figure 2 The base 10 extends upward from the top of the side facing the front of the support frame 20 to form a protrusion 111. A support groove 112 is formed between the protrusion 111 and the support frame 20. The support groove 112 is used to fix and place the smart device.

[0049] It should be noted that the smart devices proposed in this embodiment include mobile phones and digital products with wireless charging function (or with wireless charging receiving coil); of course, the smart devices in this embodiment are illustrated by mobile phones, and the same applies throughout the text.

[0050] In this way, users only need to place the bottom of the phone in the support groove 112, and the phone can be firmly attached to the front of the support bracket 20, thereby achieving wireless charging.

[0051] It is understood that the support groove 112 proposed in this embodiment is equivalent to a mobile phone stand, making it convenient for users to use their mobile phones while charging. Furthermore, to facilitate better placement of the mobile phone in the support groove 112, the support frame 20 proposed in this embodiment is inclinedly positioned on the base 10.

[0052] In one embodiment, refer to Appendix Figure 1-2 One end of the coil adjusting seat 30 is provided with a sliding block 311 that slides in accordance with the slide rail 212. Part of the sliding block 311 extends out of the slide rail 212, and the adjusting screw 50 passes through the sliding block 311 that extends out of the slide rail 212.

[0053] The other end of the coil adjustment seat 30 is recessed inward to form a receiving groove 312, and a wireless charging transmitting coil 40 is installed in the receiving groove 312.

[0054] In this way, the user rotates the adjusting screw 50, causing the thread on the adjusting screw 50 to interact with the sliding surface inside the sliding block 311. This interaction causes the sliding block 311 to slide along the axis of the adjusting screw 50 on the slide rail 212. As a result, the sliding block 311 drives the wireless charging transmitting coil 40 to move along the axis of the adjusting screw 50, thereby changing the height position of the wireless charging transmitting coil 40 on the support frame 20. This allows for precise adjustment of the position of the wireless charging transmitting coil 40, thereby improving the compatibility of the wireless charger and ensuring that the wireless charging transmitting coil 40 on the wireless charger can correctly correspond to the receiving coil on different brands of mobile phones, thus guaranteeing the charging efficiency of the mobile phone.

[0055] Furthermore, a coil shield 313 is provided between the bottom wall of the receiving groove 312 and the wireless charging transmitting coil 40.

[0056] Because the wireless charger proposed in this embodiment mainly works based on the principle of electromagnetic induction, the wireless charging transmitting coil 40 generates a changing magnetic field, which induces an electromotive force in the receiving coil of the device, thereby generating current to power the device; while the coil shield 313 (usually containing a magnetic sheet) plays a magnetic guiding role at the receiving end, so as to provide a magnetic field loop for the transmitting end magnetic field, making the magnetic field more concentrated at the receiving end of the device, thereby improving the energy transmission efficiency.

[0057] Furthermore, the coil shield 313 can limit the spread of the magnetic field, ensuring that the magnetic field only acts on the receiving coil of the mobile phone, thus ensuring the stability and safety of the wireless charger. In addition, the coil shield 313 can effectively absorb and shield the electromagnetic interference that the wireless charging transmitting coil 40 may generate during operation, protecting surrounding equipment from interference.

[0058] In one embodiment, to ensure that the adjusting screw 50 can be better fixed to the back of the support frame 20, refer to the attached diagram. Figure 2 The support frame 20 has a first fixing block 213 and a second fixing block 214 spaced apart from top to bottom along its length direction on its back side. The end of the adjusting screw 50 passes through the first fixing block 213 and the sliding block 311 in sequence and is connected to the second fixing block 214.

[0059] It should be noted that the slide 212 is located between the first fixing block 213 and the second fixing block 214.

[0060] The first fixing block 213 is located at the top of the back of the support frame 20, and the second fixing block 214 is located at the bottom of the back of the support frame 20. The end of the adjusting screw 50 passes through the first fixing block 213 and the sliding block 311 in sequence and then connects to the second fixing block 214. At this time, the knob 511 at the beginning of the adjusting screw 50 is located at the top of the first fixing block 213, and the end of the adjusting screw 50 is located inside the second fixing block 214 and does not pass through the second fixing block 214.

[0061] In one embodiment, refer to Appendix Figure 1-2 The second fixing block 214 is matched with a fastener 60 at the end of the adjusting screw 50. The fastener 60 is used to restrict the axial movement of the adjusting screw 50 and does not interfere with the rotation of the adjusting screw 50 about its axis.

[0062] Specifically, the end of the adjusting screw 50 has a mounting structure 512 that matches the end of the fastener 60. This can be a groove, a plane, or other shape, which is used to ensure that the fastener 60 can be securely installed at the end of the adjusting screw 50. This mounting structure 512 needs to ensure that the adjusting screw 50 can still rotate freely about its axis after the fastener 60 and the adjusting screw 50 are matched and connected.

[0063] In one embodiment, refer to Appendix Figure 2 The support frame 20 has a scale display area 215 on its back side and at least one side corresponding to the slide rail 212. The scale display area 215 is distributed along the sliding direction of the slide rail 212 and is used to indicate the position of the coil adjustment seat 30 or the degree of adjustment of the wireless charging transmitting coil 40.

[0064] It should be noted that the scale display area 215 includes a series of evenly distributed scale lines and / or numerical markings, used to visually indicate the position of the coil adjustment base 30 or the wireless charging transmitting coil 40 as it slides along the slide rail 212 or the adjustment distance relative to the initial position. Furthermore, the smallest unit of the scale display area 215 can be set to centimeters or millimeters, etc., depending on the actual situation, and is not limited here.

[0065] In this way, users can see the real-time position changes of the coil adjustment base 30 or the wireless charging transmitter coil 40 based on the scale display area 215, thus providing users with a precise adjustment reference. Furthermore, users can record the coil adjustment position for different brands of mobile phones. Before using a mobile phone of a specific brand, users can adjust the wireless charging transmitter coil 40 to the corresponding position using the adjustment screw 50. The corresponding mobile phone can then be placed directly on the support bracket 20 for charging, allowing for faster charging.

[0066] In one embodiment, refer to Appendix Figure 1 The bottom of the base 10 is recessed inward to form a receiving groove (not shown, the same throughout the text). The opening of the receiving groove is provided with a matching bottom cover 113. A control circuit board 70 is matched in the receiving groove. The control circuit board 70 is electrically connected to the wireless charging transmitting coil 40.

[0067] The connection between the bottom cover 113 and the opening of the receiving groove is a bolted connection.

[0068] In this way, when the wireless charger malfunctions, the maintenance personnel can open the opening of the bottom cover 113 relative to the receiving groove to expose the control circuit board 70 located in the receiving groove, thereby facilitating the maintenance personnel to inspect and repair the control circuit board 70.

[0069] Among them, refer to the appendix Figure 1-2 The base 10 has at least one charging port assembly 80 on its side wall, which is electrically connected to the control circuit board 70. This allows external power to be transmitted to the wireless charging transmitting coil 40 through the charging port assembly 80, causing the wireless charging transmitting coil 40 to generate a changing magnetic field. This magnetic field induces an electromotive force in the receiving coil of the mobile phone, thereby generating a current to charge the mobile phone.

[0070] In one embodiment, refer to Appendix Figure 1 and 3 The base 10 has at least one display screen assembly 90 on its top or side wall, and the display screen assembly 90 is electrically connected to the control circuit board 70.

[0071] Specifically, the base 10 is provided with a display screen assembly 90 on the top of the other side of the support frame 20. The display screen assembly 90 is used to display the charging power of the wireless charger in real time, so that the user can adjust the position of the wireless charging transmitting coil 40 by adjusting the screw 50, so that the wireless charger works in the optimal charging state.
