[0055] In the description of the present application, unless otherwise explicitly limited, the words such as setting, installing, connecting, etc. should be broadly understood, and the person skilled in the art can reasonably determine the specific meaning of the above words in the present application in combination with the specific content of the technical solution.

[0056] The embodiment of the present application proposes a wireless charging coil adaptation structure, which needs to be explained here, the wireless charging coil adaptation structure is used for wireless charging of a charging object, and the charging object can be a mobile phone, a tablet computer, and various electronic devices. Referring to Figures 1 to 4As shown, the wireless charging coil adaptive structure comprises a housing 100, a supporting assembly 200, a charging coil 300 and a first driving mechanism 400.

[0057] The housing 100 is configured to support the back of the charging object 800.

[0058] The supporting assembly 200 is connected to the housing 100, and the supporting assembly 200 is provided with a supporting part 210 configured to support the end of the charging object 800. The supporting assembly 200 is movable relative to the housing 100 to adjust the distance between the supporting part 210 and the housing 100 in a first direction, thereby adjusting the relative position of the charging object 800 and the housing 100 in the first direction. When the charging object 800 is supported on the supporting part 210 and kept in a stable state, the relative position relationship between the charging object 800 and the housing 100 in the first direction can be changed by adjusting the distance between the supporting part 210 and the housing 100 in the first direction. In some specific embodiments, the housing 100 has a supporting surface 101 outside, the supporting surface 101 is used to be in contact with the back of the charging object 800, and the first direction is parallel to the supporting surface 101. The first direction can be a vertical direction, or be deviated from the vertical direction by a certain angle, i.e. when the charging object 800 is charged, the charging object 800 is placed vertically or obliquely.

[0059] The charging coil 300 is movably arranged in the housing 100, and the first driving mechanism 400 is connected to the charging coil 300 to drive the charging coil 300 to move relative to the housing 100, so that the charging coil 300 is in a position suitable for charging the object coil 810 of the charging object 800.

[0060] It can be understood that the position suitable for the charging coil 300 to charge the object coil 810 of the charging object 800 can be the position corresponding to the maximum charging power of the charging coil 300, i.e. the position corresponding to the complete alignment of the charging coil 300 and the coil on the charging object 800, or the position corresponding to the charging power of the charging coil 300 being within the charging power range set by the designer.

[0061] The wireless charging coil adaptive structure provided by the embodiment of the utility model can be used for adjusting the distance between the supporting assembly 200 and the shell 100 in the first direction according to the model size of the charging object 800, so that the charging object 800 can be placed on the shell 100 and supported by the supporting part 210, and two conditions can be met, one is that the structure protruding from the back of the charging object 800, such as a camera, does not interfere with the shell 100, and the other is that the object coil 810 of the charging object 800 can be within the active range of the charging coil 300, then the first driving mechanism 400 can be used to drive the charging coil 300 to move relative to the shell 100, so that the charging coil 300 can be moved to a position suitable for charging the charging object 800, for example, the position where the charging coil 300 reaches the maximum charging power, that is, the position where the charging coil 300 is completely aligned with the coil on the charging object 800, so that the charging object 800 of various models and sizes can be adapted, and the charging coil 300 is in a position suitable for charging the object coil 810 of the charging object 800, and the charging efficiency is high.

[0062] In order to facilitate the understanding of the technical scheme of the utility model, the following will be taken as an example that the charging object 800 is a mobile phone, and the position where the charging coil 300 is suitable for charging the object coil 810 of the charging object 800 is the position where the charging coil 300 is completely aligned with the coil on the charging object 800, and a detailed description will be made in combination with the drawings.

[0063] Please refer to Figure 4 , Figure 4 which shows the state diagram when a mobile phone of a certain fixed model size is charged, and the distance between the supporting part 210 and the shell 100 in the first direction is the adjustable maximum distance. As can be seen from the figure, at this time, the coil (i.e. the object coil 810) of the mobile phone (i.e. the charging object 800) and the charging coil 300 can be aligned, and the camera does not interfere with the shell 100, but if a mobile phone of a smaller size is replaced for charging, when the mobile phone of a smaller size is placed on the wireless charging coil adaptive structure in the state shown in Figure 4 , the camera of the mobile phone may interfere with the end of the shell 100 away from the supporting part 210, so the distance between the supporting part 210 and the shell 100 in the first direction needs to be adjusted to adapt to the smaller size mobile phone, but after adjusting the distance between the supporting part 210 and the shell 100 in the first direction, when charging a mobile phone of a larger size, the coil of the mobile phone may be partially or entirely located outside the active range of the charging coil 300, which leads to the fact that the coil on the mobile phone cannot be aligned no matter how the charging coil 300 moves, so the embodiment makes the charging coil 300 move relative to the shell 100 to adjust the position, and at the same time, the distance between the supporting part 210 and the shell 100 can be adjusted relative to the shell 100, so as to adapt to the charging object 800 of various models and sizes.

[0064] Further, in some embodiments of the present application, in order to enable the charging coil 300 to move to a position suitable for charging the object coil 810 of the charging object 800, the wireless charging coil adapting structure further comprises a master control chip, which is arranged in the shell 100 and electrically connected with the first driving mechanism 400. When the charging object 800 is placed on the shell 100 to start charging, the master control chip detects the current charging power of the charging coil 300. If the current charging power is less than the preset power, the first driving mechanism 400 drives the charging coil 300 to move relative to the shell 100 until the current charging power reaches the preset power. When the current charging power reaches the preset power, the charging coil 300 is in a position suitable for charging the object coil 810 of the charging object 800.

[0065] The preset power can be the maximum charging power of the charging coil 300, or other charging power of a certain size preset by the designer, or charging power within a certain size range.

[0066] In some embodiments of the present application, as shown in Figure 4 The wireless charging coil adapting structure further comprises two clamping portions 500, which are respectively arranged on opposite sides of the shell 100 along the second direction, and the two clamping portions can be folded or unfolded relative to the shell along the second direction to clamp or release the charging object. Wherein, the second direction is perpendicular to the first direction.

[0067] It can be understood that by arranging two clamping portions 500 to clamp the charging object 800 in the second direction, the positioning of the charging object 800 in the second direction can be realized, and the charging coil 300 and the object coil 810 on the charging object 800 can be aligned.

[0068] As for how to realize the folding or unfolding of the two clamping portions 500 relative to the shell 100 in the second direction, an electric drive or a linkage with the supporting assembly 200 can be used.

[0069] For example, the form of linkage with the supporting assembly 200 can be adopted, and no power structure is arranged for driving. In some embodiments (not shown in the figure), the wireless charging coil adaptation structure further comprises a mounting portion, the mounting portion is linked with the two clamping portions 500 through a linkage assembly, and the mounting portion can move close to or away from the shell 100 in the first direction under the action of an external force. When the mounting portion moves away from the shell 100 in the first direction, it can drive the two clamping portions 500 to close relative to the shell 100. When the mounting portion moves close to the shell 100 in the first direction, it can drive the two clamping portions 500 to open relative to the shell 100. The supporting assembly 200 is arranged on the mounting portion, and the supporting assembly 200 can move and adjust in the first direction relative to the mounting portion, so as to adjust the distance between the supporting portion 210 and the mounting portion in the first direction. That is, when the position of the mounting portion is fixed, the supporting assembly 200 can also move relative to the shell 100 to adjust the distance between the supporting portion 210 and the shell 100 in the first direction.

[0070] The linkage assembly can adopt the linkage assembly used by the gravity support of a mobile phone in the prior art (not shown in the figure). For example, the patent with the application number CN201922382976.0 discloses a linkage assembly composed of a rotating gear, a first tooth portion, a second tooth portion, a third tooth portion, and a return spring. The embodiments of the utility model can adopt similar structures to realize the linkage between the mounting portion and the two clamping portions 500.

[0071] That is, the linkage assembly can be provided with one gear, three racks, and a return spring. The gear is rotatably arranged on the shell 100. The three racks are all engaged with the gear. Two of the racks are arranged in the second direction and are connected with the two clamping portions 500 respectively. The other rack is arranged in the first direction and is connected with the mounting portion. The return spring is used to apply a force to the mounting portion in the first direction close to the shell 100, so that the mounting portion has a movement tendency close to the shell 100.

[0072] When the charging object 800 is placed on the shell 100 and supported by the supporting portion 210, the gravity of the charging object 800 drives the supporting portion 210 to move away from the shell 100, thereby driving the mounting portion to move away from the shell 100, and synchronously driving the two clamping portions 500 to close and clamp the charging object 800. After the charging object 800 is clamped, the mounting portion no longer moves. At this time, the supporting assembly 200 can be moved and adjusted in the first direction relative to the mounting portion, thereby adjusting the distance between the supporting portion 210 and the shell 100 in the first direction, and adjusting the relative position of the charging object 800 and the shell 100 in the first direction. When the charging object 800 is removed from the shell 100, the return spring can drive the mounting portion to move close to the shell 100 for resetting.

[0073] For example, the movement of the clamping part 500 can be achieved by electric drive, and the supporting component 200 is not linked with the clamping part 500. In some embodiments of this utility model, refer to... Figure 3 and Figure 9 As shown, the wireless charging coil adapter structure also includes a second drive mechanism 700. The second drive mechanism 700 includes a second motor 710, a second gear 720, and two second racks 730. The second gear 720 is connected to the output end of the second motor 710 and can rotate around its own central axis under the drive of the second motor 710. The central axis of the second gear 720 is distributed along a third direction. The two second racks 730 are movably disposed in the housing 100 along a second direction. The two second racks 730 are respectively meshed with the opposite sides of the second gear 720 and are respectively connected to two clamping parts 500. The second motor 710 drives the second gear 720 to rotate, thereby driving the two second racks 730 to move synchronously in opposite directions along the second direction, so that the two clamping parts 500 are closed or opened relative to the housing 100 along the second direction. The first direction, the second direction, and the third direction are perpendicular to each other.

[0074] The following description, in conjunction with the accompanying drawings, describes how the support component 210 adjusts its distance from the housing 100 in the first direction when the support component 200 is not linked with the clamping component 500.

[0075] In some embodiments of this utility model, reference is made to Figure 1 , Figure 3 as well as Figure 5 As shown, the support assembly 200 is also provided with an adjustment plate 220, which is movably disposed on the housing 100 along the first direction, and the adjustment plate 220 has at least two fixed positions in its moving stroke. The support part 210 is disposed at the end of the adjustment plate 220 away from the housing 100 along the first direction. A positioning structure is provided between the adjustment plate 220 and the housing 100, which is used to fix the adjustment plate 220 when it moves to the fixed position.

[0076] Based on the above configuration, when it is necessary to adjust the distance between the support 210 and the housing 100 in the first direction, the positioning structure is first released from fixing the adjusting plate 220. Then, the adjusting plate 220 is moved to drive the support 210 to move in the first direction. When the adjusting plate 220 moves to the target fixed position, the positioning structure at the target fixed position is used to re-fix the adjusting plate 220, thereby realizing the adjustment of the distance between the support 210 and the housing 100 in the first direction. It should be noted that the number of fixed positions can be two, three, or more. In addition, the target fixed position refers to the fixed position that the adjusting plate 220 is required to reach according to actual needs. Different actual needs may require the adjusting plate 220 to reach different fixed positions. Therefore, the target fixed position does not specifically refer to a certain fixed position.

[0077] In some embodiments of the utility model, refer to Figure 1 And Figure 5 As shown in the drawings, the adjusting plate 220 and the supporting part 210 can be provided as an integral structure; in addition, to set the adjusting plate 220 movably on the shell 100 along the first direction, an installation channel adapted to the adjusting plate 220 can be defined at one end of the shell 100 along the first direction, the installation channel forms an installation opening 103 at the end of the shell 100, and the adjusting plate 220 can be movably arranged in the installation channel along the first direction, part of the adjusting plate 220 is located inside the installation opening 103, and part of the adjusting plate 220 is located outside the installation opening 103 and is connected to the supporting part 210; by setting the installation channel to pass through the adjusting plate 220, the adjusting plate 220 can be extended outward or inward relative to the shell 100, which can improve the space utilization and reduce the overall volume of the device.

[0078] In some embodiments of the utility model, refer to Figure 5 And Figure 10 As shown in the drawings, one of the shell 100 and the adjusting plate 220 is provided with a limiting groove 222, and the other is provided with a limiting column 130; the limiting column 130 can be arranged on the shell 100, and the limiting groove 222 can be arranged on the adjusting plate 220; wherein the limiting groove 222 is distributed along the first direction, and the limiting column 130 is inserted into the limiting groove 222; when the adjusting plate 220 is moved to the fixed position at the two end points of the movable stroke, the limiting column 130 abuts against the two side walls of the limiting groove 222 in the first direction; taking the example that two fixed positions are set, which are the first fixed position and the second fixed position, respectively, when the adjusting plate 220 is moved to the first fixed position, the limiting column 130 abuts against one end side wall of the limiting groove 222 in the first direction, and when the adjusting plate 220 is moved to the second fixed position, the limiting column 130 abuts against the other end side wall of the limiting groove 222 in the first direction.

[0079] Through the above setting, the movable stroke of the adjusting plate 220 can be limited by the cooperation of the limiting column 130 and the limiting groove 222, and when the limiting column 130 abuts against the limiting groove 222, the auxiliary positioning effect can be achieved, so as to fix the adjusting plate 220 at the corresponding fixed position by the positioning structure.

[0080] In some embodiments of the utility model, the distance between the two fixed positions at the two end points of the movable stroke of the adjusting plate 220 is greater than or equal to 5mm. Obviously, if the distance between the two fixed positions at the two end points of the movable stroke of the adjusting plate 220 is less than 5mm, the adjusting distance is too small, on the one hand, it is not convenient to arrange the positioning structure, on the other hand, due to the small adjusting distance, the adaptation degree of the wireless charging coil adaptation structure of the embodiment to the charging object 800 of different sizes is also relatively low, therefore, in the embodiment, the distance between the two fixed positions at the two end points of the movable stroke of the adjusting plate 220 is greater than or equal to 5mm, so as to improve the adaptation degree of the wireless charging coil adaptation structure of the embodiment to the charging object 800 of different sizes.

[0081] In some embodiments of the utility model, as shown in Figure 1 The positioning structure can include a positioning convex part 120 and at least two positioning grooves 221, the at least two positioning grooves 221 are arranged along the first direction, the positioning convex part 120 is arranged on one of the adjusting plate 220 and the shell 100, and the positioning groove 221 is arranged on the other one, that is, the positioning convex part 120 is arranged on the shell 100, and the positioning groove 221 is arranged on the adjusting plate 220; wherein the positioning groove 221 corresponds to the fixed position one by one, when the adjusting plate 220 moves to the fixed position, the positioning convex part 120 is embedded in the corresponding position of the positioning groove 221, and the positioning convex part 120 and the positioning groove 221 are matched to realize the positioning of the adjusting plate 220, which is simple in structure and does not occupy too much space, and is helpful to reduce the volume of the equipment.

[0082] In one specific embodiment, two fixed positions are provided, which are a first fixed position and a second fixed position, and the distance between the two fixed positions is greater than or equal to 5mm, when the adjusting plate 220 is at the first fixed position, the distance between the supporting part 210 and the shell 100 is the minimum distance in the adjustable range, and when the adjusting plate 220 is at the second fixed position, the distance between the supporting part 210 and the shell 100 is the maximum distance in the adjustable range. For example, Figure 1 The state diagram of the adjusting plate 220 at the first fixed position is shown in Figure 2 The state diagram of the adjusting plate 220 at the second fixed position is shown in Figure 4 The state diagram of the adjusting plate 220 at the second fixed position and the charging object 800 placed on the shell 100 for charging is shown in

[0083] In some embodiments of the utility model, as shown in Figure 1 And Figure 3 The positioning convex part 120 extends along the second direction, and the opposite sides of the positioning convex part 120 along the first direction are respectively provided with arc surfaces or inclined surfaces, so that the positioning convex part 120 and the positioning groove 221 can be conveniently matched and separated.

[0084] The above describes how the supporting part 210 adjusts the distance from the housing 100 in the first direction when the supporting assembly 200 is not linked with the clamping part 500. Similarly, when the supporting assembly 200 is linked with the clamping part 500, that is, the mounting part is further arranged between the clamping part 500 and the supporting assembly 200, the movement adjustment of the supporting assembly 200 relative to the mounting part can also be achieved by using a similar structure as described above, only the structure for adjusting the distance of the supporting part 210 from the housing 100 in the first direction is arranged between the supporting assembly 200 and the mounting part. Since the structure and principle are the same, only the arrangement position is changed, therefore, no further description is given.

[0085] It can be understood that the movement of the charging coil 300 driven by the first driving mechanism 400 can be linear movement or planar movement.

[0086] For example, in some embodiments of the utility model, the charging coil 300 is movably arranged in the housing 100 along the first direction, and the first driving mechanism 400 is used to drive the charging coil 300 to move relative to the housing 100 along the first direction, that is, the first driving mechanism 400 is used to drive the charging coil 300 to move linearly along the first direction.

[0087] It can be understood that although the coils on the charging objects 800 of different sizes are different in position, they are basically arranged in the middle of the back of the charging object 800. Therefore, for the charging objects 800 of different sizes, when the charging object 800 is placed on the housing 100 and supported by the supporting part 210, only the placement mode of the charging object 800 needs to be kept consistent, so that the charging coil 300 and the object coil 810 of the charging object 800 only produce misalignment in the first direction. Therefore, only the first driving mechanism 400 needs to drive the charging coil 300 to move relative to the housing 100 along the first direction. When the first driving mechanism 400 only needs to drive the charging coil 300 to move linearly along one direction, the structure of the first driving mechanism 400 will be simpler and more convenient to control.

[0088] For the convenience of understanding the technical scheme of the utility model, taking the charging object 800 as a mobile phone as an example. The coils of mobile phones of different sizes usually only produce misalignment in the length direction. Therefore, when charging different mobile phones, only the length direction of the mobile phone needs to be kept consistent with the first direction when the mobile phone is placed on the housing 100, so that the coils of different mobile phones only produce misalignment in the first direction.

[0089] Based on the above setting, it is conceivable that the first driving mechanism 400 can be an electric telescopic rod, or a hydraulic cylinder, or a motor screw mechanism. Of course, the first driving mechanism 400 can also adopt other forms.

[0090] For example, in some embodiments of the utility model, referring to Figure 1 、 Figure 3 and Figure 6 , the first driving mechanism 400 includes: a first rack 410, a first gear 420 and a first motor 430. Wherein, the first rack 410 is arranged parallel to the first direction, and the first rack 410 is connected with the charging coil 300; the first gear 420 is rotationally arranged and engaged with the first rack 410, the central axis of the first gear 420 is distributed along the third direction, the third direction is perpendicular to the first direction, and the third direction is perpendicular to the supporting surface 101 of the shell 100; the first motor 430 is connected with the first gear 420 and is used to drive the first gear 420 to rotate, so as to drive the first rack 410 to move along the first direction, thereby driving the charging coil 300 to move along the first direction.

[0091] By setting the above structure to drive the charging coil 300 to move along the first direction, the structure is simple, the space occupancy is low, and the volume of the equipment can be reduced.

[0092] In further embodiments, referring to Figure 1 and Figure 3 , the wireless charging coil adaptation structure further includes a sliding seat 900, the sliding seat 900 is used to mount the first rack 410 and the charging coil 300, so as to provide a carrier for the first rack 410 and the charging coil 300, and the sliding seat 900 is movably arranged in the shell 100 along the first direction.

[0093] Wherein, referring to Figure 3 and Figure 7 , in order to limit the movement direction of the sliding seat 900, the shell 100 is provided with a guide convex part 110 distributed along the first direction, and the sliding seat 900 is provided with a guide groove 910, the guide convex part 110 and the guide groove 910 are slidably matched along the first direction, so as to provide movement guidance for the sliding seat 900.

[0094] In some specific embodiments, a guide surface 102 parallel to the first direction and perpendicular to the third direction is defined in the shell 100, the guide convex part 110 is arranged on the guide surface 102, and the shell 100 is further provided with an anti-dropping buckle 140, the anti-dropping buckle 140 is used to cooperate with the guide surface 102 to limit the displacement of the sliding seat 900 along the third direction, and the stability of the sliding seat 900 moving along the first direction is improved. Of course, the guide convex part 110 and the guide groove 910 can be provided in multiple groups, and the guide convex part 110 can be arranged on the sliding seat 900, and the guide groove 910 is arranged on the shell 100.

[0095] In addition, referring to Figure 6 , in order to improve the space utilization and reduce the size of the device, the sliding seat 900 is provided with a mounting groove 920 distributed along the first direction, the first rack 410 is arranged on the side wall of the mounting groove 920, and the first gear 420 is embedded in the mounting groove 920. In this way, the space occupation of the first driving mechanism 400 can be reduced. It is conceivable that the first rack 410 and the sliding seat 900 can be a split structure or an integral structure.

[0096] In further embodiments, referring to Figure 1 , Figure 3 and Figure 10 , the wireless charging coil adaptive structure further comprises a detection device 600 arranged in the housing 100 and electrically connected with the first motor 430; the sliding seat 900 comprises a main body part 930 and a trigger part 940, the main body part 930 is connected to the housing 100, the first rack 410 and the charging coil 300 are both mounted on the main body part 930, the trigger part 940 is connected to the main body part 930 and is located between the two ends of the main body part 930 in the first direction; wherein when the sliding seat 900 moves to at least one end point of its active stroke, the trigger part 940 triggers the detection device 600 and feeds back to control the first motor 430 to stop driving, thereby realizing the control of the active stroke of the sliding seat 900.

[0097] It is understood that by arranging the trigger part 940 between the two ends of the main body part 930 in the first direction and triggering the detection device 600 with the trigger part 940, compared with directly triggering the detection device 600 with the end of the main body part 930, the arrangement of the detection device 600 can be facilitated, the space layout can be optimized, and the size of the device in the first direction can be reduced.

[0098] Based on the above arrangement, it is conceivable that the detection device 600 can be arranged corresponding to both end points of the active stroke of the sliding seat 900, or only corresponding to one end point of the active stroke of the sliding seat 900.

[0099] In some specific embodiments, referring to Figure 8 and Figure 10As shown, the detection device 600 includes a PCB detection board 610 and a limit switch 620. The PCB detection board 610 is disposed inside the housing 100 and electrically connected to the first motor 430. The limit switch 620 is disposed on the PCB detection board 610 and is located at the end of the sliding seat 900 near the support portion 210 on its active stroke. The limit switch 620 and the main body 930 are offset in the third direction. When the sliding seat 900 moves to the end of its active stroke near the support portion 210, the trigger portion 940 abuts against the limit switch 620 to trigger the limit switch 620 to control the first motor 430 to stop driving. When it is necessary to move the sliding seat 900 away from the support portion 210, the first motor 430 can be reversed.

[0100] It should be noted that although the limit switch 620 is only set at one end of the active stroke of the slide seat 900, the maximum stroke of the slide seat 900 moving closer to the support part 210 and the maximum stroke moving away from the support part 210 can be controlled by the program to keep the other end of the active stroke of the slide seat 900 consistent.

[0101] In a further embodiment, refer to Figure 8 As shown, in order to identify whether the mobile phone is placed on the housing 100 so as to further control the action of the first motor 430, an infrared lamp 630 is also provided on the PCB detection board 610. A filter film is provided on the outside of the housing 100 at the position corresponding to the infrared lamp 630. The filter film can filter out ultraviolet light and visible light, and allow infrared light to pass through.

[0102] The following description Figures 1 to 10 The illustration shows a method of using a wireless charging coil adapter structure according to one embodiment.

[0103] In use, the adjustment plate 220 can be adjusted to the corresponding fixed position according to the model and size of the charging object 800. Then, the charging object 800 is placed on the housing 100, the back of the charging object 800 is supported by the housing 100, and the end of the charging object 800 is supported by the support part 210. Then, the two clamping parts 500 are closed to clamp and fix the charging object 800, so that the object coil 810 of the charging object 800 is aligned with the charging coil 300 in the second direction. Finally, the charging coil 300 is driven to move in the first direction through the first driving mechanism 400 to realize the alignment of the charging coil 300 with the object coil 810 of the charging object 800.
