Description

Technical Field

[0001] The present application relates to the field of electronic technology, and in particular to a wireless charging device. Background Art

[0002] Wireless charging equipment is a technology that mainly uses the electromagnetic wave induction principle, electromagnetic wave resonance principle or other technologies that use the magnetic field as a bridge for transmitting power. By installing coils at the transmitting end and the receiving end respectively, the coil at the transmitting end sends electromagnetic signals to the outside world under the action of electricity, and the coil at the receiving end receives the electromagnetic signals and converts them into current, thereby realizing wireless charging. Wireless charging equipment is widely used in electronic equipment, smart homes, smart vehicles, smart wearable devices and other fields because it is safe and convenient, has high charging efficiency, saves design space for the charging port of the receiving end device, and improves the waterproof and dustproof performance of the receiving end device.

These drawings and text descriptions are not intended to limit the scope of the present application in any way, but to illustrate the concept of the present application to those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION

[0075] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0076] Unless otherwise defined, all technical terms used in the embodiments of the present application have the same meanings as commonly understood by those skilled in the art.

[0077] In order to make the technical solutions and advantages of the present application more clear, the implementation methods of the present application will be further described in detail below with reference to the accompanying drawings.

[0078] like Figure 1As shown, an embodiment of the present application provides a wireless charging device, which includes a housing assembly 100, a reset assembly 200 and a support member 300. The reset assembly 200 is connected to the housing assembly 100 and the support member 300 respectively. The support member 300 extends from the housing assembly 100. The support member 300 can be used to carry a first device to be charged 400. Among them, the support member 300 is configured to move in a first direction under the gravity of the first device to be charged 400, and the reset assembly 200 is configured to drive the support member 300 to move in a second direction after the first device to be charged 400 is evacuated, and the first direction is opposite to the second direction. It should be noted that the first direction refers to the direction from the top of the housing assembly 100 to the bottom of the housing assembly 100 within the bearing surface of the housing assembly 100 for carrying the first device to be charged 400. The second direction refers to the direction from the bottom of the housing assembly 100 to the top of the housing assembly 100 within the bearing surface of the housing assembly 100 for carrying the first device to be charged 400. The first device to be charged 400 may be a device with a wireless charging function, such as a mobile phone with a wireless charging function. The wireless charging device may also be provided with an interface that can be used to connect to an external power source. After the wireless charging device is connected to the external power source through the interface, power can be supplied to the charging module in the wireless charging device, thereby realizing the wireless charging function.

[0079] Generally, a charging module for wireless charging will be provided inside the first device to be charged 400, and a charging module for wireless charging will also be provided inside the wireless charging device, for example, the charging module may be a coil assembly, etc. When the coil center of the charging module in the first device to be charged 400 is roughly aligned with the coil center of the charging module in the wireless charging device, wireless charging can be performed. It is understandable that the surface of the first device to be charged 400 in contact with the wireless charging device is generally provided with a functional module 410 protruding away from the first device to be charged 400, such as a camera module, etc. After the first device to be charged 400 is placed on the support 300, the support 300 can move in the first direction until the first device to be charged 400 reaches a position where the bottom of its functional module 410 abuts against the top side wall of the housing assembly 100. Generally, the distance between the side of the first device to be charged 400 that abuts against the top side wall of the shell assembly 100 and the center of the coil of the charging module inside the first device to be charged 400 is a first distance, and the distance between the top side wall of the shell assembly 100 and the center of the coil of the charging module inside the wireless charging device is a second distance, and the first distance is approximately the same as the second distance.

[0080] With the wireless charging device provided in the embodiment of the present application, since the support member 300 can be moved in the first direction by the gravity of the first device to be charged 400, until the bottom of the functional module 410 of the first device to be charged 400 abuts against the top side wall of the shell assembly 100, the first device to be charged 400 and the support member 300 stop moving, so that the coil center of the charging module inside the first device to be charged 400 of different models after the movement can be aligned with the coil center of the charging module inside the wireless charging device, thereby realizing the wireless charging process. In other words, the wireless charging device provided in the embodiment of the present application can charge a variety of different models of first devices to be charged 400, thereby improving the compatibility of the wireless charging device. At the same time, since the reset component 200 can drive the support member 300 to move in the second direction after the first device to be charged 400 is evacuated, the support member 300 can be flexibly reset, thereby improving the flexibility of the wireless charging device.

[0081] The following is combined with Figures 1 to 11 The structure and function of each component of the wireless charging device provided in the embodiment of the present application are described in more detail.

[0082] Combination Figure 1 and Figure 2 As shown, in some embodiments, the housing assembly 100 includes a first housing portion 110 and a second housing portion 120, and the first housing portion 110 and the second housing portion 120 are buckled with each other. The loading surface 128 of the first housing portion 110 facing away from the second housing portion 120 is used to carry the first device to be charged 400, and the support member 300 extends from the loading surface 128. Therefore, when the support member 300 moves along the first direction, the first device to be charged 400 can move along the loading surface 128 of the first housing portion 110.

[0083] In some embodiments, the wireless charging device further includes a heat sink (not shown in the figure), which is disposed inside the housing assembly 100. The first housing portion 110 is provided with a plurality of through slots 140 extending in a first direction and arranged side by side, wherein the airflow formed by the heat sink flows out from the inside of the housing assembly 100 through the through slots 140 to the outside of the housing assembly 100. It is understandable that when the loading surface 128 of the first housing portion 110 carries the first device 400 to be charged, the airflow formed by the heat sink can dissipate the heat of the first device 400 to be charged in a timely manner, so as to reduce the heat generated by the first device 400 to be charged during the charging process, and achieve a better heat dissipation effect. Where necessary, the heat sink can be a heat dissipation device such as a fan.

[0084] It should be noted that the first housing portion 110 and the second housing portion 120 may be clamped together by a clamping structure, may be fixedly connected by fixing members such as bolts or screws, or may be bonded together by an adhesive.

[0085] like Figure 2 As shown, in some embodiments, the second housing portion 120 is provided with a first groove 121, the first groove 121 is recessed in a direction away from the first housing portion 110, and the reset assembly 200 is located in the first groove 121. Therefore, when the first housing portion 110 and the second housing portion 120 are buckled with each other, the reset assembly 200 inside the housing assembly 100 can be protected.

[0086] like Figure 2 As shown, in some embodiments, the reset assembly 200 includes a first slider 210 and at least one first elastic member 220, the two ends of the first elastic member 220 are respectively connected to the second housing portion 120 and the first slider 210, and the first slider 210 is connected to the support member 300. Wherein, under the elastic force constraint of the first elastic member 220, the first slider 210 can slide in the first direction and the second direction. It should be noted that the first elastic member 220 can extend or shrink in the first direction or the second direction. The first slider 210 can be a regular rectangular, square or other shape, or an irregular shape. In some embodiments, the two sides of the first slider 210 are respectively parallel to and abut against the bottom of the first groove 121 and the surface of the first housing portion 110 opposite to the object-carrying surface 128. Thereby, it can be ensured that the first slider 210 moves smoothly in the first direction and the second direction, thereby driving the support member 300 to move smoothly in the first direction and the second direction.

[0087] like Figure 2 As shown, in some embodiments, the first slider 210 is provided with at least one mounting groove 211, and the mounting groove 211 corresponds to the first elastic member 220 one by one, and at least a portion of the first elastic member 220 is located in the corresponding mounting groove 211. It should be noted that the mounting groove 211 can be a through groove or a groove. Figure 2 The mounting groove 211 shown is a groove. By setting the mounting groove 211, the first elastic member 220 can be limited to prevent the first elastic member 220 from being offset during the deformation process. In some embodiments, the extension direction of the mounting groove 211 is the first direction. Such a setting can ensure that the first elastic member 220 can move smoothly in the first direction or the second direction with the first slider 210, avoid the support member 300 from being offset during the movement, ensure that the first device to be charged 400 can always move smoothly in the first direction or the second direction, and further ensure that the coil center of the charging module of the first device to be charged 400 can be more accurately aligned with the coil center of the charging module of the wireless charging device, so as to efficiently perform wireless charging.

[0088] like Figure 2As shown, in some embodiments, the reset assembly 200 includes two first elastic members 220, and the two first elastic members 220 are arranged side by side in a direction perpendicular to the first direction. The first slider 210 is provided with two mounting grooves 211, and each mounting groove 211 corresponds to a first elastic member 220. Such an arrangement can ensure that the forces on both sides of the first slider 210 are relatively balanced, and avoid the situation in which the support member 300 is tilted or offset during the movement, resulting in the coil center of the charging module of the wireless charging device and the coil center of the charging module of the first device to be charged 400 cannot be aligned, that is, to ensure that the wireless charging process can proceed normally.

[0089] like Figure 2 As shown, in some embodiments, the first slider 210 is provided with at least one first through hole 212. The first housing portion 110 is provided with at least one second through hole 111, and the first through hole 212 corresponds to the second through hole 111 one by one. The support member 300 includes a first connecting portion 310 and a main body portion 320, one end of the first connecting portion 310 is connected to the main body portion 320, and the other end of the first connecting portion 310 is inserted into the first through hole 212 through the second through hole 111, and the main body portion 320 is used to carry the first device to be charged 400. Thus, the main body portion 320 can move along the first direction under the gravity of the first device to be charged 400, and the main body portion 320 can also drive the first slider 210 to move along the first direction, and then the first slider 210 can drive the first elastic member 220 to be in a stretched state. When the first device to be charged 400 is evacuated, the first elastic member 220 returns to the initial state, thereby driving the first slider 210 to move in the second direction, so that the first slider 210 can drive the main body 320 to move in the second direction through the first connecting portion 310, thereby realizing the movement and reset process of the reset assembly 200. In some embodiments, the first slider 210 is provided with two first through holes 212 at the bottom near the first housing portion 110, and the two first through holes 212 are arranged side by side in a direction perpendicular to the first direction, so that the support member 300 can be driven to move in the first direction or the second direction more smoothly, ensuring that the forces on both sides of the support member 300 are balanced, avoiding the situation in which the support member 300 is tilted or offset during the movement, resulting in the coil center of the charging module of the wireless charging device and the coil center of the charging module of the first device to be charged 400 cannot be aligned, that is, ensuring that the wireless charging process can proceed normally.

[0090] like Figure 3As shown, in some embodiments, the main body 320 includes a support block 321 and a partition 322, and the two sides of the partition 322 are respectively connected to the side of the support block 321 close to the first housing portion 110 and the loading surface 128 of the first housing portion 110. It should be noted that by providing the partition 322, the friction between the support block 321 and the loading surface 128 of the first housing portion 110 can be reduced, thereby reducing the degree of wear of the support block 321 and the first housing portion 110, and extending the service life of the wireless charging device. In some embodiments, the partition 322 and the support block 321 are connected by bonding. In some embodiments, the partition 322 and the first connecting portion 310 are an integrally formed structure. The material of the partition 322 is different from that of the first housing portion 110, and the friction between the partition 322 and the first housing portion 110 is low. The material of the partition 322 can be TPU (Thermoplasticpolyurethanes, thermoplastic polyurethane elastomer rubber).

[0091] like Figure 3 As shown, in some embodiments, at least one second groove 213 is provided on the side of the first slider 210 away from the first housing portion 110, the second groove 213 is recessed toward the first housing portion 110, and a first through hole 212 is provided at the bottom of the second groove 213. The portion of the first connecting portion 310 that penetrates into the second groove 213 through the first through hole 212 is clamped together with the side wall of the second groove 213 through a concave-convex structure. By clamping the first connecting portion 310 and the side wall of the second groove 213 together, the support member 300 can be prevented from being separated from the first through hole 212, thereby preventing the support member 300 from being separated from the first housing portion 110.

[0092] Combination Figure 2 and Figure 3 As shown, in some embodiments, the first groove 121 includes a first groove wall 122 and a second groove wall 123. The first slider 210 includes a first side wall 214 and a second side wall 215, wherein the first side wall 214 is close to the first groove wall 122, and the second side wall 215 is close to the second groove wall 123. The first side wall 214 is slidably connected to the first groove wall 122, and the second side wall 215 is slidably connected to the second groove wall 123. Thus, the first slider 210 can move more flexibly and more smoothly in the first groove 121.

[0093] Combination Figure 2 and Figure 3As shown, in some embodiments, the first side wall 214 is provided with a second connection portion 216, and the second side wall 215 is provided with a third connection portion 217. The first groove wall 122 is provided with a fourth connection portion 124, and the second groove wall 123 is provided with a fifth connection portion 125. The second connection portion 216 and the third connection portion 217 are convex portions or concave portions, and the fourth connection portion 124 is adapted to be slidably connected with the second connection portion 216; the fifth connection portion 125 is adapted to be slidably connected with the third connection portion 217. It can be understood that the first slider 210 and the first groove 121 connected by the convex portion and the concave portion are more convenient for disassembly or assembly of the two.

[0094] Combination Figure 2 , Figure 3 , Figure 5 and Figure 6 As shown, in some embodiments, the reset assembly 200 further includes a first guide member 230 and a second guide member 240, and the first guide member 230 and the second guide member 240 both extend along the first direction. The first side of the first guide member 230 abuts against the first groove wall 122, and the second side of the first guide member 230 is provided with a sixth connection portion 231; the first side of the second guide member 240 abuts against the second groove wall 123, and the second side of the second guide member 240 is provided with a seventh connection portion 241. The sixth connection portion 231 and the seventh connection portion 241 are convex portions or concave portions, and the second connection portion 216 is adapted to be slidably connected with the sixth connection portion 231; and the third connection portion 217 is adapted to be slidably connected with the seventh connection portion 241. It should be noted that by providing the first guide member 230 and the second guide member 240, the first side wall 214 can be separated from the first groove wall 122, and the second side wall 215 can be separated from the second groove wall 123. Thus, the friction between the first slider 210 and the first side wall 214 and the second side wall 215 of the first groove 121 can be reduced, and the service life of the wireless charging device can be extended. In some embodiments, the first guide member 230 and the second guide member 240 are respectively connected to the first housing portion 110. For example, both ends of the first guide member 230 are respectively connected to the first housing portion 110, and both ends of the second guide member 240 are respectively connected to the first housing portion 110.

[0095] Combination Figure 7 and Figure 8 As shown, in some embodiments, the wireless charging device further includes a locking assembly 500 and a second charging module 600, and the locking assembly 500 is separated from the reset assembly 200. The locking assembly 500 is connected to the housing assembly 100 and the second charging module 600, respectively.

[0096] Among them, when the locking assembly 500 is in the first locking state, it is used to limit the second charging module 600 inside the shell assembly 100; when the locking assembly 500 is in the second locking state, it is used to limit a part of the second charging module 600 outside the shell assembly 100. It should be noted that the second charging module 600 is generally used to charge the second device to be charged 700. For example, the second device to be charged 700 can be a smart wearable device with a wireless charging function such as a smart bracelet. Such a setting can increase the diversity of the functions of the wireless charging device and further improve the compatibility of the wireless charging device with different devices to be charged. By setting the locking assembly 500, the position of the second charging module 600 can be fixed more flexibly.

[0097] like Figure 8 As shown, in some embodiments, the second housing portion 120 is further provided with a seventh groove 126, and the seventh groove 126 is recessed in a direction away from the first housing portion 110. The seventh groove 126 is used to accommodate the second charging module 600, and the seventh groove 126 includes a third groove wall 1261 and a fourth groove wall 1262 opposite to each other, and the third groove wall 1261 and the fourth groove wall 1262 are both perpendicular to the extension direction of the second charging module 600. The fourth groove wall 1262 is provided with a third through hole 130, and a part of the second charging module 600 can extend to the outside of the housing assembly 100 through the third through hole 130. Since the second charging module 600 can be retracted into the seventh groove 126 when not in use, the second charging module 600 can be better protected to prevent collision with objects outside the housing assembly 100 and damage. It should be noted that the second charging module 600 can realize the wireless charging function and is generally also provided with a coil. When the coil center of the second charging module 600 is aligned with the coil center of the charging module in the second device to be charged 700, wireless charging can be performed.

[0098] Combination Figures 8 to 10 As shown, in some embodiments, the seventh groove 126 further includes a fifth groove wall 1263 and a sixth groove wall 1264 opposite to each other, and the fifth groove wall 1263 and the sixth groove wall 1264 are both parallel to the extension direction of the second charging module 600. The second housing portion 120 is further provided with an eighth groove 127, and the eighth groove 127 is connected to the sixth groove wall 1264 at the connection 140. A first card slot 620 and a second card slot 630 are sequentially provided on one side of the second charging module 600 close to the sixth groove wall 1264 in the extension direction of the second charging module 600. The locking assembly 500 includes a toggle mechanism, which is located in the eighth groove 127, and the toggle mechanism is retractable in a direction perpendicular to the extension direction of the second charging module 600. Thus, the toggle mechanism can extend into the seventh groove 126 through the connection 140, or the toggle mechanism can be retracted into the eighth groove 127 through the connection 140.

[0099] When the toggle mechanism extends from the connection 140 and snaps into the first slot 620, the second charging module 600 is limited inside the housing assembly 100, so that the housing assembly 100 can better protect the second charging module 600. When the toggle mechanism extends from the connection 140 and snaps into the second slot 630, a portion of the second charging module 600 is limited outside the housing assembly 100. This prevents the second charging module 600 from being separated from the housing assembly 100.

[0100] like Figure 8 As shown, in some embodiments, the eighth groove 127 includes a seventh groove wall 1271 and an eighth groove wall 1272 opposite to each other, the seventh groove wall 1271 and the eighth groove wall 1272 are both parallel to the extension direction of the second charging module 600, and the seventh groove wall 1271 is connected to the sixth groove wall 1264 at the connecting point 140. The toggle mechanism includes a third elastic member 1001 and a toggle member 1002 connected to each other, the two ends of the third elastic member 1001 are respectively connected to the eighth groove wall 1272 and the toggle member 1002, and the end of the toggle member 1002 not connected to the third elastic member 1001 can extend from the connecting point 140 to the first card slot 620 or the second card slot 630. It should be noted that the third elastic member 1001 can be a component with elastic deformation ability such as a spring. By setting the toggle member 1002, the second charging module 600 can be limited more flexibly.

[0101] Combination Figures 8 to 11As shown, in some embodiments, the fourth groove wall 1262 of the seventh groove 126 is further provided with a fourth through hole 129. The toggle member 1002 includes a first portion 1003 and a second portion 1004, wherein the first portion 1003 is located in the eighth groove 127, one end of the first portion 1003 is connected to the third elastic member 1001, and the other end of the first portion 1003 can extend from the connecting portion 140 into the first card slot 620 or the second card slot 630. One end of the second portion 1004 is connected to the first portion 1003, and the other end of the second portion 1004 extends in a direction away from the first portion 1003 and passes through the fourth through hole 129 to the outside of the second housing portion 120, wherein the second portion 1004 can move in the fourth through hole 129 in a direction perpendicular to the seventh groove wall 1271. It should be noted that the fourth through hole 129 is a long strip through hole, and the second portion 1004 can move along the length direction of the long strip through hole. The movable distance of the second part 1004 in the fourth through hole 129 is the first distance, and the movable distance of the first part 1003 when the end close to the second charging module 600 is inserted into the first card slot 620 or the second card slot 630 from the connecting part 140 is the second distance, and the first distance is not less than the second distance. In this configuration, the user only needs to move the second part 1004 to flexibly drive the first part 1003 to be separated from the first card slot 620 or the second card slot 630. When the user releases the force applied to the second part 1004, the first part 1003 can be re-inserted into the first card slot 620 or the second card slot 630 from the connecting part 140 by the elastic force of the third elastic member 1001.

[0102] Combination Figure 5 and Figure 8 As shown, in some embodiments, the locking assembly 500 further includes a baffle 530, one end of which is connected to the eighth groove wall 1272, and the other end of which extends in the direction of the seventh groove wall 1271, and the extending direction of the baffle 530 is parallel to the groove bottom of the eighth groove 127. The two side walls of the toggle member 1002 parallel to the groove bottom of the eighth groove 127 respectively abut against the side walls of the baffle 530 close to the groove bottom of the eighth groove 127 and the groove bottom of the eighth groove 127. It can be understood that the toggle member 1002 can be sandwiched between the baffle 530 and the groove bottom of the eighth groove 127 in a certain manner, so as to limit the toggle member 1002 to a certain extent, so that the toggle member 1002 can move smoothly, and avoid the toggle member 1002 from being offset and unable to be inserted into the first slot 620 or the second slot 630.

[0103] like Figure 8As shown, in some embodiments, the locking assembly 500 includes at least one guide rod 510 and at least one second elastic member 520, the second elastic member 520 corresponds to the guide rod 510 one by one, and the second elastic member 520 is sleeved on the outer wall of the guide rod 510. One end of the guide rod 510 is connected to the third groove wall 1261, and the other end of the guide rod 510 extends in a direction away from the third groove wall 1261. The second charging module 600 is provided with at least one blind hole 610, the opening of the blind hole 610 faces the third groove wall 1261, and the blind hole 610 is sleeved on the outer wall of the second elastic member 520.

[0104] When the second charging module 600 is located inside the shell assembly 100, the second elastic member 520 is in a compressed state; when a portion of the second charging module 600 can extend to the outside of the shell assembly 100 through the third through hole 130, the second elastic member 520 is in an extended state. Figure 8 The figure shows a schematic diagram of the second charging module 600 having two blind holes 610 arranged side by side in a direction perpendicular to the moving direction of the second charging module 600. It can be understood that the cooperation of the guide rod 510, the second elastic member 520 and the blind hole 610 can ensure that the second charging module 600 can move smoothly in a preset direction. In some embodiments, the guide rod 510 is perpendicular to the third slot wall 1261.

[0105] like Figure 8 As shown, in some embodiments, the wireless charging device further includes a first spacer 800 and a second spacer 900, and the first spacer 800 and the second spacer 900 both extend along the moving direction of the second charging module 600.

It should be noted that by providing the first spacer 800 and the second spacer 900, the wear between the outer wall of the second charging module 600 and the fifth slot wall 1263 and the sixth slot wall 1264 can be reduced, thereby extending the service life of the second charging module 600. In some embodiments, the material of the first spacer 800 and the material of the second spacer 900 are TPU material.

[0106] Combination Figure 8 and Fig.11As shown, in some embodiments, a guide groove 1265 is provided at the bottom of the seventh groove 126, and the guide groove 1265 extends along the moving direction of the second charging module 600. A protrusion 640 is connected to the side of the second charging module 600 close to the bottom of the seventh groove 126, and the protrusion 640 extends in a direction away from the second charging module 600, and the protrusion 640 can move in the guide groove 1265. In some embodiments, the extension direction of the guide groove 1265 is the same as the extension direction of the guide rod 510. Thereby, it can be ensured that the second charging module 600 can always move smoothly in a preset direction and extend out of the second housing portion 120 or retract into the seventh groove 126.
