Description

Technical Field

[0001] This application belongs to the field of communication technology, and specifically relates to a charging device. Background Technology

[0002] With the development of charging technology, wireless chargers have emerged to improve the convenience of charging electronic devices. Wireless chargers eliminate the need for power cords, using electromagnetic waves to charge electronic devices wirelessly. Therefore, wireless charging eliminates the need for users to carry charging cables, making charging electronic devices much more convenient.

[0003] However, when wirelessly charging electronic devices, the coil of the wireless charger and the coil inside the electronic device need to communicate with each other. Therefore, the relative positions of the two are critical, and the electronic device cannot move freely relative to the wireless charger. Consequently, it is inconvenient for users to operate the electronic device during charging. Clearly, current charging solutions cannot simultaneously meet the dual requirements of convenient charging and easy user operation of electronic devices during charging. Summary of the Invention

[0004] The purpose of this application is to provide a charging device that can solve the problem in related technologies that cannot simultaneously meet the needs of convenient charging and convenient user operation of electronic devices during the charging process.

[0005] This application provides a charging device, including a device housing, a charging coil, and a charging cable, wherein:

[0006] The charging coil is disposed within the device housing, which has a support surface. With the electronic device supported by the support surface, the charging coil wirelessly charges the electronic device.

[0007] At least a portion of the charging cable can extend outside the device housing, and a first end of the charging cable is provided with a first charging connector, through which the charging device can be electrically connected to the electronic device.

[0008] In this embodiment, the charging device can wirelessly charge electronic devices using a charging coil or wired charging using a charging cable. Users can choose the charging method according to their needs. Therefore, this solution satisfies the need for convenient charging by selecting wireless charging, while wired charging eliminates the need for the electronic device to be placed on the charging device, allowing for flexible placement and convenient operation by the user. Thus, this solution effectively balances the needs for both convenient charging and easy user operation of the electronic device during charging. Attached Figure Description

[0030] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0031] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0032] The charging device provided in this application will be described in detail below with reference to the accompanying drawings, through specific embodiments and application scenarios.

[0033] refer to Figures 1-9 This application discloses a charging device, which includes a device housing 100, a charging coil 400, and a charging cable S. The device housing 100 serves as the mounting base for the charging coil 400 and the charging cable S. The charging coil 400 is used for wireless charging of an electronic device 910, and the charging cable S is used for wired charging of the electronic device 910.

[0034] The charging coil 400 is disposed within the device housing 100, and the device housing 100 is provided with a support surface 111, such as... Figure 3As shown, when the electronic device 910 is supported by the support surface 111, the electronic device 910 is located in the wireless charging position of the charging device. At this time, the charging coil 400 is electrically connected to the electronic device 910, and the charging coil 400 wirelessly charges the electronic device 910. Specifically, the electronic device 910 has a receiving coil inside. When the electronic device 910 is supported by the support surface 111, the charging coil 400 and the receiving coil are communicatively connected, and electromagnetic induction is generated between the charging coil 400 and the receiving coil to realize wireless charging of the electronic device 910.

[0035] At least a portion of the charging cable S can extend outside the device housing 100, and a first end of the charging cable S is provided with a first charging connector 210. The charging device can be electrically connected to the electronic device 910 through the first charging connector 210. Specifically, the electronic device 910 is provided with a first charging interface, and the first charging connector 210 can be inserted into the first charging interface to realize the electrical connection between the electronic device 910 and the charging cable S, at which time the charging cable S charges the electronic device 910. Optionally, when the charging cable S is not charging, the charging cable S can be entirely located inside the device housing 100. When the charging cable S needs to be charged, a portion of the charging cable S extends outside the device housing 100, or the entire charging cable S extends outside the device housing 100, so that the first charging connector 210 extends outside the device housing 100, facilitating the electrical connection between the first charging connector 210 and the first charging interface of the electronic device 910, thereby realizing wired charging of the electronic device 910 by the charging device. It should be noted that the first charging connector 210 can always be located outside the device housing 100. The connection between the first charging connector 210 and the electronic device can be achieved regardless of whether at least a part of the charging cable S is located outside the device housing 100.

[0036] In this embodiment, the charging device can wirelessly charge the electronic device 910 using the charging coil 400 or wiredly charge it using the charging cable S. Users can choose the charging method according to their needs. Therefore, this solution satisfies the need for convenient charging by selecting wireless charging, while by selecting wired charging, the electronic device 910 does not need to be placed on the charging device when wired charging is performed using the charging cable S. Thus, the position of the electronic device 910 can be flexibly changed, allowing users to easily operate it. It is evident that this solution can simultaneously address both the needs for convenient charging and the ease of user operation of the electronic device during charging.

[0037] In one optional embodiment, the charging cable S is wound around the device housing 100. Specifically, the portion of the charging cable S inside the device housing 100 is wound around the cable. Optionally, a spool may be provided inside the device housing 100, and the portion of the charging cable S inside the device housing 100 is directly wound onto the spool. In this way, the charging cable S is neatly stored, avoiding the charging cable S from being messy and occupying too much space inside the device housing 100. Moreover, the charging cable S is less likely to affect other components inside the device housing 100.

[0038] The charging cable S has a charging state and a retracted state. When the charging cable S is in the charging state, the length of the portion of the charging cable S outside the device housing 100 is a first length; when the charging cable S is in the retracted state, the length of the portion of the charging cable S outside the device housing 100 is a second length, and the first length is greater than the second length. When the charging cable S switches from the retracted state to the charging state, the length of the portion of the charging cable S inside the device housing 100 decreases, and the length of the portion of the charging cable S outside the device housing 100 increases, facilitating electrical connection between the first charging connector 210 and the electronic device 910. When the charging cable S switches from the charging state to the retracted state, the length of the portion of the charging cable S outside the device housing 100 decreases, the length of the portion of the charging cable S inside the device housing 100 increases, and the portion inside the device housing 100 is further wound up.

[0039] The charging cable S can be manually wound onto the device housing 100, but manual winding is slow and the state switching efficiency of the charging cable S is low. To solve this problem, the device housing 100 also includes a drive mechanism 500, which is connected to the charging cable S and can drive the charging cable S to wind or unwind. Optionally, the drive mechanism 500 can be connected to either the end or the middle of the charging cable S. The drive mechanism 500 achieves winding or unwinding of the charging cable S by driving the charging cable S to rotate. Specifically, during the winding process driven by the drive mechanism 500, the charging cable S switches from a charging state to a stored state; during the unwinding process driven by the drive mechanism 500, the charging cable S switches from a stored state to a charging state. In this way, by using the drive mechanism 500 to wind or unwind the charging cable S, the winding or unwinding speed is increased, the state switching efficiency of the charging cable S is improved, which is beneficial for the effective wired charging process and also for the rapid storage of the charging cable S.

[0040] Because the charging cable S is relatively soft, when the drive mechanism 500 drives the charging cable S to release it, the released portion of the charging cable S does not easily extend directly outside the device housing 100. This portion tends to accumulate inside the device housing 100, which is detrimental to the electrical connection between the charging cable S and the electronic device 910. Therefore, in one embodiment, the drive mechanism 500 only drives the charging cable S to wind; the user can directly pull the first end of the charging cable S manually to increase the length of the portion of the charging cable S outside the device housing 100, thus realizing the release process of the charging cable S. In this way, the charging cable S can be directly pulled manually to realize the release process of the charging cable S, avoiding the accumulation of the released charging cable S inside the device housing 100, and saving the driving energy of the drive mechanism 500.

[0041] In the scheme of this application, the charging device includes a battery module 700, which is electrically connected to the charging cable S and the charging coil 400 respectively, and the battery module 700 supplies power to the charging cable S and the charging coil 400; or, the charging cable S includes a first charging segment 200 and a second charging segment 300, at least a portion of the first charging segment 200 and at least a portion of the second charging segment 300 can extend outside the device housing 100, the first end of the first charging segment 200 is electrically connected to the first end of the second charging segment 300, the second end of the first charging segment 200 is provided with a first charging connector 210, the second end of the second charging segment 300 is provided with a second charging connector 310, and the charging device can be electrically connected to the power supply device through the second charging connector 310. In the latter embodiment, the first charging line segment 200, the second charging line segment 300, and the charging coil 400 are arranged sequentially. The first charging line segment 200 and the second charging line segment 300 are located between the support surface 111 and the charging coil 400. Moreover, the second charging line segment 300 is electrically connected to the first charging line segment 200 and the charging coil 400 respectively. When the second charging line segment 300 is electrically connected to the power supply device through the second charging connector 310, the second charging line segment 300 can simultaneously supply power to the first charging line segment 200 and the charging coil 400.

[0042] Specifically, the power supply device is equipped with a second charging interface, and a second charging connector 310 can be inserted into the second charging interface to electrically connect the power supply device with the second charging cable segment 300. At this time, the power supply device supplies power to the first charging cable segment 200 and the charging coil 400 through the second charging cable segment 300. Optionally, the power supply device can be a power bank or a fixed power source. The second charging connector 310 can be directly electrically connected to the power supply device, or it can be electrically connected to the power supply device through an adapter such as a plug.

[0043] Optionally, when the charging cable is not charging, the first charging segment 200 and the second charging segment 300 can be entirely located within the device housing 100. When the charging cable needs charging, a portion of the first charging segment 200 extends outside the device housing 100, or the entire first charging segment 200 extends outside the device housing 100, so that the first charging connector 210 extends outside the device housing 100, facilitating electrical connection between the first charging connector 210 and the first charging interface of the electronic device 910; simultaneously, a portion of the second charging segment 300 extends outside the device housing 100, or the entire second charging segment 300 extends outside the device housing 100, so that the second charging connector 310 extends outside the device housing 100, facilitating electrical connection between the second charging connector 310 and the second charging interface of the power supply device, enabling the power supply device to supply power to the charging device. It should be noted that the second charging connector 310 can always be located outside the device housing 100; connection between the second charging connector 310 and the electronic device can be achieved regardless of whether at least a portion of the second charging segment 300 is located outside the device housing 100.

[0044] By adopting a charging cable S including a second charging segment 300, the power supply device can continuously supply power to the first charging segment 200 and the charging coil 400, thereby enabling the charging device to continuously charge the electronic device 910 and increase the charging capacity of the charging device.

[0045] In one alternative embodiment, such as Figure 5As shown, the charging device also includes a first circuit board 610 and a second circuit board 620. The first circuit board 610 is disposed between the first charging line segment 200 and the second charging line segment 300. The first circuit board 610 is fixedly connected and electrically connected to the first end of the first charging line segment 200 and the first end of the second charging line segment 300, respectively. That is, the second charging line segment 300 is electrically connected to the first charging line segment 200 through the first circuit board 610. Furthermore, the second circuit board 620 is disposed between the second charging line segment 300 and the charging coil 400. Circuit board 620 is fixedly connected and electrically connected to the first end of the second charging segment 300 and the charging coil 400, respectively. That is, the second charging segment 300 is electrically connected to the charging coil 400 through the second circuit board 620. The first charging segment 200, the first circuit board 610, the second charging segment 300, the second circuit board 620, and the charging coil 400 are arranged sequentially. At this time, the first end of the first charging segment 200, the first end of the second charging segment 300, the first circuit board 610, the second circuit board 620, and the charging coil 400 form an integral structure. Optionally, the first end of the first charging segment 200 and the first circuit board 610, the first end of the second charging segment 300 and the first circuit board 610 can be fixedly connected by welding or other methods. The first end of the second charging segment 300 and the second circuit board 620, and the charging coil 400 and the second circuit board 620 can also be fixedly connected by welding or other methods.

[0046] At least one of the first circuit board 610 and the second circuit board 620 is connected to the driving mechanism 500. The driving mechanism 500 drives the first circuit board 610, the second circuit board 620, and the first ends of the first charging line segment 200 and the second charging line segment 300 to rotate around the winding central axis A. Optionally, the driving mechanism 500 can be connected to either the first circuit board 610 or the second circuit board 620. The driving mechanism 500 directly drives the first circuit board 610 or the second circuit board 620 to rotate, thereby driving the first ends of the first charging line segment 200 and the second charging line segment 300 to rotate around the winding central axis A, realizing the winding or unwinding of the first charging line segment 200 and the second charging line segment 300.

[0047] Since both the first circuit board 610 and the second circuit board 620 are plate-shaped structures, a first winding space for accommodating the first charging line segment 200 can be formed between the first circuit board 610 and the device housing 100. A second winding space for accommodating the second charging line segment 300 can also be formed between the first circuit board 610 and the second circuit board 620. Under the limiting effect of the device housing 100 and the first circuit board 610, the first charging line segment 200 can be directly wound in the first winding space. Moreover, under the limiting effect of the first circuit board 610 and the second circuit board 620, the second charging line segment 300 can be directly wound in the second winding space.

[0048] Therefore, the first circuit board 610 and the second circuit board 620 serve as electrical conversion components, respectively electrically connected to the first charging line segment 200 and the charging coil 400. The first circuit board 610 and the second circuit board 620 also serve as limiting components, which facilitates the smooth winding process of the first charging line segment 200 and the second charging line segment 300, eliminating the need for a separate winding shaft and helping to simplify the structure of the charging device.

[0049] In an optional embodiment, combined with Figure 7 and Figure 8 As shown, the drive mechanism 500 is located on the side of the charging coil 400 facing away from the second circuit board 620. The drive mechanism 500 includes a drive source 510, a transmission assembly 520, and a rotating drum 530. The inner wall of the device housing 100 is provided with a support column 121. The axis of the support column 121 is the winding central axis A. The rotating drum 530 is sleeved on the outside of the support column 121. The rotating drum 530 can rotate relative to the support column 121 around the winding central axis A. Moreover, the rotating drum 530 is connected to at least one of the first circuit board 610 and the second circuit board 620. The drive source 510 is connected to the rotating drum 530 through the transmission assembly 520 to drive the rotating drum 530 to rotate. Optionally, the second circuit board 620 has a first opening at its center, and the rotating drum 530 passes through the center of the charging coil 400 and extends into the first opening, with the outer wall of the rotating drum 530 connected to the wall of the first opening; or, both the first circuit board 610 and the second circuit board 620 have a first opening at their centers, and the rotating drum 530 sequentially passes through the center of the charging coil 400, the first opening of the second circuit board 620, the center of the second charging line segment 300, and the first opening of the first circuit board 610, with the outer wall of the rotating drum 530 connected to the walls of the first openings of the first circuit board 610 and the first openings of the second circuit board 620, respectively. The driving source 510 can be a drive motor, a pneumatic motor, or other component that can drive the rotating drum 530 to rotate via the transmission assembly 520.

[0050] With this configuration, the drive source 510 drives the rotating drum 530 to rotate through the transmission assembly 520. Since the rotating drum 530 is located at the winding center axis A, the rotating drum 530 can stably drive the first end of the first charging line segment 200, the first circuit board 610, the first end of the second charging line segment 300, the second circuit board 620, and the charging coil 400 to rotate at the same time.

[0051] In one embodiment, the winding center shaft A is parallel to the output shaft of the drive source 510. This requires the drive source 510 to be positioned along the direction of the winding center shaft A, which can occupy excessive space inside the device housing 100, resulting in an excessively thick device housing 100 and hindering the portability of the charging device. Therefore, in another embodiment, the winding center shaft A intersects with the output shaft of the drive source 510. In this embodiment, the winding center shaft A is perpendicular to the output shaft of the drive source 510. The transmission assembly 520 includes a first bevel gear 521 and a second bevel gear 522. The first bevel gear 521 is disposed on the output shaft of the drive source 510, with its bevel teeth distributed circumferentially along the output shaft. The second bevel gear 522 is disposed on the rotating drum 530, with its bevel teeth distributed circumferentially along the rotating drum 530. The first bevel gear 521 and the second bevel gear 522 mesh with each other. Thus, the drive source 510 can be set in the direction intersecting with the winding center axis A, so the drive source 510 will not occupy too much space inside the device housing 100 in the direction where the winding center axis A is located, which is beneficial to reducing the thickness of the device housing 100 and improving the portability of the charging device.

[0052] In this embodiment, the drive mechanism 500 only drives the first end of the first charging cable segment 200 and the first end of the second charging cable segment 300 to achieve the winding process. The release process of the first charging cable segment 200 and the second charging cable segment 300 can be achieved manually. However, since the rotating drum 530 will also rotate in the opposite direction during the release process, it is easy to affect the drive source 510 through the transmission component 520. To solve this problem, the charging device also includes a drive device for driving the first bevel gear 521 and the drive source 510 to move, such as a telescopic cylinder. One end of the telescopic cylinder is a fixed end, and the other end of the telescopic cylinder is connected to the drive source 510. When it is necessary to manually release the first charging cable segment 200 and the second charging cable segment 300, the drive device drives the drive source 510 to disengage the first bevel gear 521 from the second bevel gear 522. At this time, the reverse rotation of the rotating drum 530 will not affect the drive source 510. When the drive mechanism 500 needs to drive the first charging line segment 200 and the second charging line segment 300, the drive device drives the drive source 510, causing the drive source 510 to drive the first bevel gear 521 to reset, and the first bevel gear 521 and the second bevel gear 522 to re-mesh.

[0053] In an optional embodiment, the charging device further includes a battery module 700, which is disposed within the device housing 100. The drive source 510 is a drive motor, which is electrically connected to the battery module 700. The first end of the second charging line segment 300 is also electrically connected to the battery module 700. Optionally, the battery module 700 is located on the side of the charging coil 400 facing away from the second circuit board 620, i.e., the battery module 700 and the drive mechanism 500 are located on the same side of the charging coil 400, facilitating electrical connection between the battery module 700 and the drive motor. Thus, when the second charging segment 300 is electrically connected to the power supply equipment, the second charging segment 300 supplies power to the battery module 700 so that the battery module 700 stores electricity. In turn, the battery module 700 can drive the drive motor, causing the first end of the first charging segment 200, the first circuit board 610, the first end of the second charging segment 300, the second circuit board 620, and the charging coil 400 to rotate as a whole around the winding center axis A, thereby realizing the winding process of the first charging segment 200 and the second charging segment 300.

[0054] Of course, in other embodiments, the battery module 700 can be electrically connected to the first end of the first charging line segment 200, and the battery module 700 supplies power to the first charging line segment 200. In this case, the charging device can be used as a power bank.

[0055] Optionally, the charging device also includes a control button, which is located on the outer surface of the device housing 100 and is electrically connected to the drive motor. The user controls the start and stop of the drive motor through the control button.

[0056] In this embodiment, as Figure 6 As shown, the second charging line segment 300 has three circuits. The first circuit connects the first end of the second charging line segment 300 to the first end of the first charging line segment 200 via the first circuit board 610. The second circuit connects the first end of the second charging line segment 300 to the charging coil 400 via the second circuit board 620. The third circuit connects the first end of the second charging line segment 300 to the battery module 700. It should be noted that... Figure 6 In the circuit, the source end refers to the end where the second charging line segment 300 is located, and the sink end refers to the end where the first charging line segment 200 is located.

[0057] In one optional embodiment, the charging device further includes at least one of a first positioning component and a second positioning component 800. The first positioning component includes a first magnetic component and a first metal component. One of the first magnetic component and the first metal component is disposed on the first charging cable segment 200, and the other is disposed on the first circuit board 610. When the first charging cable segment 200 is wound within the device housing 100, the first magnetic component attracts the first metal component. Optionally, the first magnetic component is disposed on the edge of the first circuit board 610, and the first metal component is a first metal collar sleeved around the outer periphery of the first charging cable segment 200. Furthermore, the surfaces of the first magnetic component and the first metal collar are respectively mating arc-shaped structures to increase their contact area. Using the first magnetic component and the first metal component, the first charging cable segment 200 in its wound state is positioned, that is, the end of the wound portion of the first charging cable segment 200 is positioned, ensuring the neatness of the wound portion and preventing the end of the wound portion from being too loose.

[0058] like Figure 9 As shown, the second positioning component 800 includes a second magnetic component 810 and a second metal component 820. One of the second magnetic component 810 and the second metal component 820 is disposed on the second charging cable segment 300, and the other is disposed on the first circuit board 610. When the second charging cable segment 300 is wound inside the device housing 100, the second magnetic component attracts the second metal component 820. Optionally, the second magnetic component 810 is disposed on the edge of the first circuit board 610, and the second metal component 820 is a second metal collar sleeved on the outer periphery of the second charging cable segment 300. Moreover, the surfaces of the second magnetic component 810 and the second metal collar are respectively mating arc-shaped structures to increase the contact area between the two. In this way, the second magnetic component 810 and the second metal component 820 are used to position the second charging cable segment 300 in the wound state, that is, to position the end of the wound portion of the second charging cable segment 300, ensuring the neatness of the wound portion and preventing the end of the wound portion from being too loose.

[0059] In optional embodiments, such as Figure 4 and Figure 7As shown, the device housing 100 includes a first housing portion 110 and a second housing portion 120 connected together. The first housing portion 110 is provided with a first groove, and the second housing portion 120 is provided with a second groove 123. The first groove and the second groove 123 can together form a receiving space for accommodating the charging coil 400, the first charging line segment 200, and the second charging line segment 300. The groove wall of the first groove is provided with a first opening for the first charging line segment 200 to extend into, and the first opening is connected to the groove opening of the first groove. The groove wall of the second groove 123 is provided with a second opening 122 for the second charging line segment 300 to extend into, and the second opening 122 is connected to the groove opening of the second groove 123. Thus, since both the first opening and the second opening 122 are open openings, when installing the first charging cable segment 200 and the second charging cable segment 300, the first charging cable segment 200 can directly extend into the first opening through the groove of the first groove, and the second charging cable segment 300 can directly extend into the second opening 122 through the groove of the second groove 123, which facilitates the installation of the first charging cable segment 200 and the second charging cable segment 300.

[0060] In this embodiment, the first shell portion 110 is provided with a support surface 111, and the support column 121 is disposed on the inner wall surface of the second shell portion 120. Optionally, the first shell portion 110 and the second shell portion 120 can be connected by a detachable method such as snap-fit, which facilitates the installation or removal of various components inside the equipment housing 100.

[0061] In one optional embodiment, the first opening and the second opening 122 are located on the same side of the device housing 100. However, when a user manually operates the first charging cable segment 200 or the second charging cable segment 300, the device housing 100 must first be fixed in position before pulling the second end of the first charging cable segment 200 or the second charging cable segment 300, resulting in a poor user experience. Therefore, in another embodiment, the first opening and the second opening 122 are located opposite each other. This way, the second ends of the first charging cable segment 200 and the second charging cable segment 300 are located on opposite sides of the device housing 100, reducing the likelihood of interference between them. Furthermore, when the user manually operates on both the first charging cable segment 200 and the second charging cable segment 300 simultaneously, it is convenient to pull them out to both sides at the same time without needing to fix the device housing 100 before pulling on either segment, thus facilitating operation and improving the user experience.

[0062] In the scheme of this application, such as Figure 5As shown, the charging device also includes a heat sink 410, which is disposed inside the device housing 100 and adjacent to the charging coil 400. Optionally, the heat sink 410 is a heat sink sheet, which can be a foam sheet with thermal conductivity. The heat sink sheet is disposed on the side of the charging coil 400 facing away from the second circuit board 620, that is, between the charging coil 400 and the device housing 100. The drive mechanism 500 is located on the side of the heat sink facing away from the charging coil 400. Moreover, a second opening is provided at the center of the heat sink sheet, and the rotating cylinder 530 passes through the second opening of the heat sink sheet, the center of the charging coil 400, and the first opening of the second circuit board 620 in sequence. In this way, the heat sink 410 dissipates the heat generated by the charging coil 400 during operation in a timely manner, preventing the charging coil 400 from overheating and affecting the wireless charging efficiency.

[0063] The embodiments of this application have been described above with reference to the accompanying drawings. However, this application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of this application without departing from the spirit and scope of the claims, and all of these forms are within the protection scope of this application.
