DETAILED DESCRIPTION

[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] There are significant differences in the design of wireless charging receiving coils among mobile phones of different brands and models. For example, the receiving coil of the iPhone is positioned lower, while the receiving coil of some Samsung models is positioned higher. This design difference, coupled with the fact that the built-in transmitting coils of traditional folding magnetic two-in-one wireless chargers are mostly fixed and difficult to adjust, often makes it difficult to accurately align the transmitting coil and receiving coil in actual use, resulting in a significant reduction in energy transmission efficiency during wireless charging and unnecessary energy loss.

[0021] To this end, the present invention provides a foldable magnetic two-in-one wireless charger. Figure 1 As shown, it includes a base plate 1, with support legs 11 fixed at the four corners of the bottom of the base plate 1, a movable support plate 12 hinged on one side of the top surface of the base plate 1, a first slide groove 13 is provided inside the movable support plate 12, a rectangular slide plate 14 is slidably connected to the middle of the first slide groove 13, a transmitting coil 15 is provided in the middle of the rectangular slide plate 14, an adjustment component is provided in the middle of the movable support plate 12, and a locking group is provided in the middle of the movable support plate 12.

[0022] For details, see Figures 1 to 7 and Figures 9 and 10 As shown, the adjustment component includes a main slide 2, two groups of support blocks 21, a screw rod 22 and a threaded sleeve 23. The main slide 2 is opened in the middle of the back of the movable support plate 12. The two support blocks 21 are respectively fixed to the two ends of the main slide 2. The two ends of the screw rod 22 are respectively rotatably connected to the middle of the two groups of support blocks 21. The threaded sleeve 23 is threadedly connected to the screw rod 22.

[0023] The adjusting assembly also includes two groups of limit slides 3, two groups of first limit slide grooves 31, a driven gear 32 and a second slide groove 33. The two limit slides 3 are respectively fixed on both sides of the middle of the threaded sleeve 23, and the two first limit slide grooves 31 are respectively opened on both sides of the middle of the main slide groove 2. The ends of the two limit slides 3 away from each other are respectively slidably connected to the middle of the two groups of first limit slide grooves 31, and the ends of the two groups of limit slides 3 away from each other are respectively fitted with the first limit slide grooves 31, the driven gear 32 is fixed to one end of the screw rod 22, and the second slide groove 33 is opened in the middle of the movable support plate 12 near the driven gear 32.

[0024] The adjusting assembly also includes a driving rack plate 4, a shift rod 41, two groups of limiting slides 42 and two groups of second limiting slides 43. The driving rack plate 4 is slidably connected to the middle of the second slide 33. The driving rack plate 4 and the driven gear 32 are meshed with each other. The shift rod 41 is fixed to the middle of the driving rack plate 4. The two limiting slides 42 are respectively fixed to the upper and lower sides of the driving rack plate 4. The two second limiting slides 43 are respectively opened on the upper and lower sides of the second slide 33. The two limiting slides 42 are respectively slidably connected to the middle of the two groups of second limiting slides 43, and the two sides of the two groups of limiting slides 42 are respectively fitted with the two sides of the two groups of second limiting slides 43. A limiting mechanism is provided on both sides of the driving rack plate 4.

[0025] During operation, if a mobile phone needs to be charged, the back of the mobile phone can be placed stably on the movable support plate 12 , and then the charging operation of the mobile phone can be successfully completed with the help of the transmitting coil 15 .

[0026] When the position of the transmitting coil 15 needs to be adjusted, the lever 41 can be pulled. In the process of pulling the lever 41, the driving rack plate 4 will be driven to slide in the middle of the second slide groove 33. When the driving rack plate 4 slides, it will synchronously drive the limiting slide 42 connected to it to move. During the movement, the limiting slide 42 will slide in the middle of the second limiting slide groove 43. Through the mutual cooperation between the limiting slide 42 and the second limiting slide groove 43, the sliding trajectory of the component driving rack plate 4 can be effectively restricted, thereby significantly improving the stability of the driving rack plate 4 during the sliding process, ensuring the accuracy and smoothness of the entire adjustment process.

[0027] Given that the driving rack plate 4 and the driven gear 32 are in a meshing relationship, when the driving rack plate 4 slides, it will push the driven gear 32 to rotate. When the driven gear 32 rotates, it will drive the screw rod 22 connected thereto to move synchronously, so that the screw rod 22 rotates in the middle of the support block 21. When the screw rod 22 rotates, it will drive the threaded sleeve 23 and the limiting slide 3 to move together. At this time, the movement of the limiting slide 3 is restricted by the first limiting slide groove 31, so that it slides in the middle of the first limiting slide groove 31. The sliding of the limiting slide rod 3 will change the movement trajectory of the threaded sleeve 23, so that the threaded sleeve 23 drives the rectangular slide 14 and the transmitting coil 15 to slide up and down in the middle of the first slide groove 13, ultimately achieving precise adjustment of the position of the transmitting coil 15.

[0028] This step can flexibly adapt to mobile phones of different brands and models by adjusting the settings of the component. Specifically, the adjustment component can adjust the position of the component transmitting coil 15 so that it is aligned with the built-in receiving coil of the mobile phone. This design effectively reduces the problems caused by the different positions of the receiving coils of different types of mobile phones, and avoids the low energy transmission efficiency that is easily caused by the position deviation between the receiving coil and the component transmitting coil 15. If there is a deviation in the position, the energy transmission will be seriously hindered during the charging process, resulting in unnecessary energy loss, which not only reduces the charging speed, but also causes a series of adverse consequences such as unstable charging. The application of the adjustment component prevents such situations from occurring.

[0029] For further information, see Figure 2 and Figures 6 to 8 As shown, the limiting mechanism includes two groups of limiting plates 5, two groups of transverse axes 51, multiple groups of triangular slots 52 and two groups of baffles 53. The two limiting plates 5 are respectively fixed to the two sides of the driving rack plate 4, the two transverse axes 51 are respectively fixed to the two ends of the second slide groove 33, the triangular slots 52 are opened on the upper and lower sides of the two groups of transverse axes 51, the two baffles 53 are fixed to the side of the two groups of limiting plates 5 away from the driving rack plate 4, and the two transverse axes 51 are respectively slidably connected to the middle part of the two groups of limiting plates 5.

[0030] The limiting mechanism also includes two groups of sliding columns 6, two groups of triangular clamping plates 61 and two groups of limiting pads 62. The two sliding columns 6 are respectively slidably connected to the middle part of the two groups of baffles 53. The two triangular clamping plates 61 are respectively fixed to the ends of the two groups of sliding columns 6 that are close to each other. The two limiting pads 62 are respectively fixed to the ends of the two groups of sliding columns 6 that are away from each other.

[0031] The limiting mechanism also includes two groups of first tension springs 7 and two groups of guide columns 71. The ends of the two first tension springs 7 that are away from each other are respectively connected to the side of the two groups of limiting pads 62 close to the sliding column 6, and the ends of the two first tension springs 7 that are close to each other are respectively connected to the side of the two groups of baffles 53 that are away from each other. The two guide columns 71 are fixed to the side of the two groups of triangular clamps 61 close to the baffle 53, and the two guide columns 71 are slidably connected to the two groups of baffles 53.

[0032] During operation, when the rack plate 4 is driven by sliding, it will drive the limit plate 5 to move synchronously. During the movement, the limit plate 5 will drive the baffle 53, the slide column 6 and the triangular clamping plate 61 to move. At this time, the triangular clamping plate 61 will contact the horizontal axis 51 during its movement. The triangular clamping plate 61 is affected by the uneven surface of the horizontal axis 51 caused by the opening of the triangular clamping groove 52, which will drive the slide column 6 to slide up and down in the middle of the baffle 53. The slide column 6 will squeeze the first tension spring 7 when sliding, so that the first tension spring 7 is compressed and stores energy under the action of pressure. When the triangular clamping plate 61 moves to When the triangular card slot 52 is in place, the first tension spring 7 will release energy and drive the sliding column 6 and the triangular card plate 61 to slide toward the triangular card slot 52. At the same time, the triangular card plate 61 will drive the guide column 71 to move synchronously when moving, and the guide column 71 will slide up and down in the middle of the baffle 53 when moving, thereby limiting the movement trajectory of the triangular card plate 61 and improving its stability during movement. When the position of the transmitting coil 15 is adjusted and the sliding drive rack plate 4 is stopped, the triangular card plate 61 will be stuck in the triangular card slot 52, thereby cooperating with the horizontal axis 51 to limit the position of the drive rack plate 4.

[0033] This step fixes the position of the driving rack plate 4 by setting the limiting mechanism, thereby reducing the possibility that the driving rack plate 4 will undergo unexpected displacement due to the lack of necessary limiting measures and external interference factors when there is no need to slide the driving rack plate 4, thereby driving the lead screw 22 to rotate, and ultimately causing the transmitting coil 15 to passively change its original position and deviate from the predetermined track, thereby affecting the stable charging of the mobile phone.

[0034] Among them, see Figure 1 、 Figure 2 、 Figure 9 and Figure 10As shown, the locking assembly includes a third slide groove 8, two groups of first clamping plates 81 and two groups of rectangular slide grooves 82. The third slide groove 8 is opened at the top of the movable support plate 12, the two first clamping plates 81 are respectively fixed to the two sides of the bottom of the movable support plate 12, and the two rectangular slide grooves 82 are respectively opened on both sides of the third slide groove 8.

[0035] The locking assembly also includes a transverse slide 9 and multiple groups of second tension springs 91. The two ends of the transverse slide 9 are respectively slidably connected to the middle of the two groups of rectangular slide grooves 82. One end of the second tension spring 91 is connected to the top of the transverse slide 9, and the other end of the second tension spring 91 is connected to the inner wall of the top of the third slide groove 8.

[0036] The engaging assembly further includes two sets of second clamping plates 10 , one end of each of the two second clamping plates 10 is fixed to one side of the horizontal slide 9 .

[0037] During operation, when the mobile phone is placed on the movable support plate 12 for charging, the bottom of the mobile phone can be placed on the first card plate 81, and then the second card plate 10 is pulled to drive the horizontal slide 9 to slide in the rectangular slide groove 82. The horizontal slide 9 will squeeze the second tension spring 91 when sliding, so that the second tension spring 91 is compressed and stores energy. Then align the top of the mobile phone with the second card plate 10 and release the second card plate 10. At this time, the second tension spring 91 will release energy and drive the horizontal slide 9 and the second card plate 10 to move toward the top of the mobile phone due to the lack of tension, so as to cooperate with the first card plate 81 to clamp the mobile phone.

[0038] This step, through the setting of the snap-fit ​​assembly, can clamp and fix mobile phones of different sizes and shapes, thereby improving the stability of the mobile phone during the charging process, reducing the problem of poor charging contact caused by shaking and displacement of the mobile phone during charging, and greatly improving the safety and stability of charging, bringing users a more convenient and efficient charging experience.

[0039] To sum up, this effectively solves the significant differences in the design of wireless charging receiving coils among mobile phones of different brands and models. For example, the receiving coil of the iPhone is positioned lower, while the receiving coil of some Samsung models is positioned higher. This design difference, coupled with the fact that the built-in transmitting coils of traditional folding magnetic two-in-one wireless chargers are mostly fixed and difficult to adjust, often makes it difficult to accurately align the transmitting coil and the receiving coil in actual use, thereby greatly reducing the energy transmission efficiency during the wireless charging process and causing unnecessary energy loss.
