Charging assembly, charger and charging device

Technical Field

The present disclosure relates to the field of charging technology, and more particularly, to a charger, a charging assembly mated with the charger, and a charging device including the charger and the charging assembly.

Background

The charging device may be connected to electronic devices such as a smart phone, a tablet computer, etc. through a port such as a USB port, thereby charging the electronic devices. Currently, the rapid charging technology is rapidly developing and widely used. The fast charging technique enables the battery to reach or approach a full charge state in a relatively short time, which greatly shortens the charging time of the electronic device or electronic product, facilitates the use of the electronic device or electronic product by a user and thus improves the user experience. With the development of rapid charging technology, the charging power of some charging devices is increasing from the previous 5W and 10W to 30W, 60W, and even more than 100W.

However, the current charging device still has many disadvantages. For example, some charging devices are typically only capable of providing higher power to electronic devices that employ a common charging protocol standard. In addition, common charging devices such as wall sockets are prone to port damage due to frequent plugging and require either an integral replacement or more complex maintenance once the port is damaged which would render the common charging device unusable.

Detailed Description

Embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While embodiments of the present disclosure are illustrated in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art. Alternative embodiments will become apparent to those skilled in the art from the following description without departing from the spirit and scope of the disclosure.

The term "comprising" and variations thereof as used herein means open ended, i.e., "including but not limited to. The term "or" means "and/or" unless specifically stated otherwise. The term "based on" means "based at least in part on". The terms "one example embodiment" and "one embodiment" mean "at least one example embodiment. Other explicit and implicit definitions are also possible below.

As described above, by means of the quick charging technique, the charging device can supply higher power to the electronic apparatus to be charged, thereby completing the charging in a relatively short time. Some international organizations and powerful companies have developed common charging protocol standards for fast charging. Meanwhile, different electronic product manufacturers (such as mobile phone manufacturers) also issue respective proprietary charging protocol standards. In other words, there are a number of different fast charge protocol standards in fact on the market today. Thus, due to the mismatch of the charging protocol standards, the charging device employing the public charging protocol standard cannot provide higher charging power for the electronic device employing the private charging protocol standard, and vice versa, resulting in failure to implement the quick charging function, which limits the usability of the charging device.

Embodiments of the present disclosure provide improvements in charging devices. By arranging the protocol circuit in the charging assembly separable from the charger, the charging assembly, and thus the charging protocol standard employed by the charging device, can be replaced relatively easily as required. In this way, the charging assembly can be selected and installed on the charger according to the charging protocol standard of the equipment to be charged, so that the quick charging function is realized for the equipment to be charged with different charging protocol standards, the performance and flexibility of the charging device are effectively improved, and the application range of the charging device is expanded. In addition, since the port component of the charging device needs to be frequently connected (e.g., in a pluggable manner) to the charging port of the device to be charged, and thus damage is prone to occur, by providing the port component in the replaceable charging assembly, the charging assembly can be easily separated from the charger when the port component is damaged, thereby replacing the charging assembly or the port component in the charging assembly, which avoids the need to integrally replace the charging device, or reduces the maintenance difficulty after the port component is damaged.

Fig. 1 shows a schematic circuit block diagram of a charging apparatus 1000, a power supply 2000, and a device to be charged 3000 according to an embodiment of the present disclosure. As shown in fig. 1, the charging apparatus 1000 may connect an external power supply 2000 to the device to be charged 3000 and convert power from the external power supply 2000 into power required by the device to be charged 3000, thereby realizing a charging or power supplying operation for the device to be charged 3000, for example, charging the battery 3001 of the device to be charged 3000. By way of example, the power supply 2000 may include a utility grid, an energy storage device such as a battery pack, a super capacitor, a switching power supply connected to the utility grid or the energy storage device, or any other type of power supply facility, or any combination thereof. The device to be charged 3000 may be a mobile terminal such as a cell phone, tablet computer, or other type of electronic device that includes a rechargeable battery. The charging device 1000 may be, for example, a public or household charging device of a wall outlet type, and may charge the device to be charged 3000 through, for example, a port such as a USB interface. However, it will be appreciated that the type of charging device 1000 is not limited thereto, and may be other suitable types of charging apparatus, such as a cell phone charger.

Fig. 2 shows a schematic circuit block diagram of a charging device 1000 according to an embodiment of the present disclosure, fig. 3 shows a perspective view of the charging device 1000 according to an embodiment of the present disclosure, and fig. 4 shows an exploded view of the charging device 1000 according to an embodiment of the present disclosure. As shown in fig. 2 to 4, the charging device 1000 includes a charging assembly 100 and a charger 200. The charging assembly 100 may be detachably mounted to the charger 200 so as to constitute the charging device 1000 together with the charger 200. That is, the charging device 1000 may be assembled from two relatively independent components, i.e., the charging assembly 100 and the charger 200, through a simple coupling operation.

Fig. 5 illustrates a perspective view of the charging assembly 100 according to an embodiment of the present disclosure, and fig. 6A to 6C illustrate top, side, and bottom views, respectively, of the charging assembly 100 according to an embodiment of the present disclosure. As shown in fig. 2, 5, and 6A to 6C, the charging assembly 100 includes a port member 110, the port member 110 being adapted to be coupled to a charging port of the device to be charged 3000 to output charging power to the device to be charged 3000. As an example, the port part 110 may be engaged by a connection wire or directly engage a charging port of the device to be charged 3000, whereby the port part 110 may be connected to the device to be charged 3000 by means of a simple operation such as plugging and unplugging, so that the charging apparatus 1000 and the charging assembly 100 thereof supply charging power to the device to be charged 3000. In some embodiments of the present disclosure, port component 110 may be a USB port. The USB port can support power transmission and data transmission, and has the advantages of small occupied space, support of hot plug, plug and play, flexible connection mode, high transmission rate and the like.

According to an embodiment of the present disclosure, the charging assembly 100 comprises a protocol circuit 120, the protocol circuit 120 being configured to communicate with the device to be charged 3000 via the port component 110 to determine a charging power applicable to the device to be charged 3000, and to generate an indication signal indicative of the charging power for the charger 200. As an example, the protocol circuit 120 may include a protocol chip and its peripheral circuits or chips. The protocol circuit 120 of a single charging assembly 100 or a protocol chip thereof may support a particular one or more charging protocols. The one or more charging protocols may include various public or private charging protocols, such as PD, QC, PE, VOOC, SCP and FCP, chargeTurbo, flashCharge, as well as other existing or future developed charging protocols. By means of the protocol circuit 120, the charging device 1000 may communicate with the apparatus to be charged 3000 (e.g. with the controller 3002 of the apparatus to be charged 3000) to confirm whether the charging device 1000 and the apparatus to be charged 3000 support the same fast charging protocol. In case the charging device 1000 and the device to be charged 3000 support the same fast charging protocol, the protocol circuit 120 may receive charging voltage, current or power information of the device to be charged 3000, for example, from the controller 3002 of the device to be charged 3000, thereby ensuring that the charging device 1000 fast charges the device to be charged 3000 with a higher charging power that the device to be charged 3000 can withstand. Further, if the charging assembly 100 determines that the charging protocols between the charging device 1000 and the apparatus to be charged 3000 do not match, the charging assembly 100 may cause the charging device 1000 to charge the apparatus to be charged 3000 with lower safe power. Depending on whether the charging protocols match, charging assembly 100 may generate an indication signal indicative of the charging power and send the indication signal to charger 200 to cause charger 200 to generate the appropriate power to charge device 3000 to be charged. In one embodiment, the protocol circuit 120 may also include a microcontroller or micro-control chip, which may be provided separately or integrated with respect to the protocol chip for assisting the protocol chip in enabling the determination of the charging power.

According to an embodiment of the present disclosure, the charging assembly 100 includes a connection terminal set 130, the connection terminal set 130 being coupled to the protocol circuit 120 and the port part 110 and configured to be electrically connected with the charger 200 when the charging assembly 100 is mounted to the charger 200. As an example, the connection terminal set 130 may include an appropriate number of conductive terminals, and may directly contact the conductive members of the charger 200 through a simple operation so as to electrically connect the charging assembly 100 to the charger 200. Thus, the charging assembly 100 may receive power from the charger 200 to provide power to the device 3000 to be charged via the port member 110. Further, by means of the connection terminal group 130, the charging assembly 100 may also communicate with the charger 200, for example, an indication signal generated by the protocol circuit 120 indicating the charging power can be transmitted to the charger 200 via the connection terminal group 130, so that the charger 200 provides an appropriate power according to the indication signal.

In some embodiments of the present disclosure, the connection terminal set 130 includes at least one power transfer terminal 131 and at least one data transfer terminal 132, the at least one power transfer terminal 131 being coupled to the port member 110, and the at least one data transfer terminal 132 being coupled to the protocol circuit 120. Specifically, when the charging assembly 100 is mounted to the charger 200, the protocol circuit 120 may transmit data related to a desired charging power to the charger 200 through the data transmission terminal 132, and transmit power from the charger 200 to the charging assembly 100 through the power transmission terminal 131 and further to the port part 110 to be provided to the device to be charged 3000 connected to the port part 110. In some embodiments, at least one power transfer terminal 131 includes a plurality of conductive terminals that protrude. By providing a plurality of conductive terminals, higher power can be efficiently transferred between the charger 200 and the charging assembly 100, and excessive contact resistance is avoided. Further, since a protruding conductive terminal (i.e., a male plug type terminal, such as a conductive contact pin) is provided at the side of the charging assembly 100, a recessed conductive terminal (i.e., a female plug type terminal) may be provided at the side of the charger 200. In this way, personnel can be effectively prevented from directly contacting the exposed charging components of the charger 200, thereby improving the safety of the charging device.

In some embodiments of the present disclosure, the charging assembly 100 further includes a circuit board 180. The port member 110, the protocol circuit 120, and the connection terminal group 130 may be disposed on the circuit board 180. In this way, the port component 110, the protocol circuit 120 and the connection terminal set 130 can be carried and connected in a simple and compact manner within a single module.

Fig. 7 illustrates an exploded view of the charging assembly 100 according to an embodiment of the present disclosure. The charging assembly 100 may further include a cover 170, the cover 170 housing the protocol circuit 120 and exposing the port member 110 and the connection terminal set 130. As an example, the cover 170 may enclose the circuit board 180 and thus the protocol circuit 120 disposed on the circuit board 180, thereby isolating at least the protocol circuit 120 from the external environment to protect the protocol circuit 120. The cover 170 may also be provided with an opening 171. The opening 171 may expose the port member 110 to the external environment so that the charging port of the device to be charged 3000 can be electrically and mechanically connected to the port member 110. Further, the cover 170 may only partially surround the circuit board 180, exposing a side of the circuit board 180 where the connection terminal group 130 is disposed. Thereby, the exposed connection terminal group 130 can be conveniently electrically and mechanically connected to the corresponding conductive member of the charger 200.

In some embodiments of the present disclosure, a fastening structure 172 may be provided on the cover 170, the fastening structure 172 being adapted to mechanically engage with the charger 200 to secure the charging assembly 100 to the charger 200. As an example, the fastening structure 172 may be an engagement member such as a clasp, and may mate with the fastening structure 172 on the charger 200, thereby achieving a secure mating of the charging assembly 100 with the charger 200.

It will be appreciated that since the charging assembly 100 is a replaceable assembly with respect to the charger 200, a plurality of replaceable charging assemblies 100 may be provided, and the protocol circuits 120 of different charging assemblies 100 may each support a different charging protocol. These charging assemblies 100 may be unified or standardized modular assemblies that facilitate their adaptation to a greater number of charging devices or chargers. In this case, the user can select and install the charging component matched or compatible with the charging protocol of the device to be charged for the charging device according to the charging requirement of the device to be charged, so that a single charging device can be used to provide higher charging power for multiple devices to be charged with different charging protocols to realize the function of quick charging, and the charging performance of the charging device is utilized to the greatest extent. Further, a port component such as a USB port is liable to be damaged due to frequent plugging operations, and in the event of damage to the port component, the entire charging device will not be able to continue to be used even if the main body circuit and the component are normal. By arranging the port component in the replaceable charging assembly, the charging assembly can be disassembled under the condition that the port component is damaged so as to replace the new charging assembly, or the disassembled charging assembly can be maintained conveniently, for example, the port component of the charging assembly is replaced. Therefore, the service life of the charging device is prolonged, and the maintenance difficulty and maintenance cost of the charging device are reduced.

Fig. 8 shows a perspective view of a charger 200 according to an embodiment of the present disclosure, and fig. 9A to 9C show top, side, and bottom views, respectively, of the charger 200 according to an embodiment of the present disclosure.

As shown in fig. 2, 8, and 9A-9C, the charger 200 is adapted to removably mount the charging assembly 100 and includes a power conversion circuit 220, the power conversion circuit 220 being adapted to be coupled to an external power source 2000. As an example, the power conversion circuit 220 may be connected to the external power supply 2000 via the power supply terminal 210 to receive power from the power supply 2000. The power conversion circuit 220 may include a power supply circuit portion 221 and an associated control and drive circuit portion 222. The power supply circuit part 221 may be, for example, a flyback circuit or other suitable type of DC-DC conversion circuit, and may convert input power into required DC power under the control of the control and drive circuit part 222. In one embodiment, charger 200 may also include a rectifier 240 for rectifying AC power from an AC power source connected to power terminal 210 to DC power and input to power conversion circuit 220. It is to be appreciated that rectifier 240 may be a component separate from power conversion circuit 220 or may be integrated into power conversion circuit 220, as embodiments of the present disclosure are not limited in this regard. In addition, the rectifier 240 may not be provided in the case where the external power supply 2000 is a DC power supply.

According to an embodiment of the present disclosure, the charger 200 includes a connection terminal set 230, the connection terminal set 230 being coupled to the power conversion circuit 220 and configured to be electrically connected with the connection terminal set 130 in the charging assembly 100 when the charging assembly 100 is mounted to the charger 200. Specifically, the connection terminal group 230 of the charger 200 may correspond to the connection terminal group 130 of the charging assembly 100 and be electrically contacted or connected with the connection terminal group 130 when the charging assembly 100 is mounted to the charger 200 to provide functions of power transmission and data transmission.

In some embodiments of the present disclosure, charger 200 includes a housing 270, and power conversion circuit 220 is disposed within housing 270, wherein housing 270 is provided with a receiving groove 271 and a fastening structure 272 for securing charging assembly 100. As an example, when the charging assembly 100 is mounted to the charger 200, the electrical and electronic components of the charging assembly 100 may be accommodated in the accommodation groove 271, and the fastening structure 272 of the case 270 may be engaged with the fastening structure 172 of the cover 170 in a mating manner with each other. For example, the fastening structure 172 may be a ramp-like boss with resiliency, and the fastening structure 272 may be a recess capable of mating with the ramp-like boss, or vice versa. Thus, the ramp-like boss may naturally slide into the recess and complete the fastening operation during installation of the charging assembly 100. It will be appreciated that the manner in which the charging assembly 100 is secured to the charger 200 is not so limited, and may be in other suitable manners as long as they can be removably assembled together. In some embodiments, the connection terminal group 230 may be disposed at the bottom of the receiving groove 271. Thus, when the charging assembly 100 is disposed to the receiving groove 271, the connection terminal group 130 of the bottom of the circuit board 180 of the charging assembly 100 will electrically contact the connection terminal group 130 of the bottom of the receiving groove 271, thereby completing the electrical connection between the charging assembly 100 and the charger 200.

In this way, the electrical and electronic components of the charging assembly 100 are completely surrounded by the housing 270 of the charger 200 and the cover 170 of the charging assembly 100 to protect the electrical and electronic components from external damage and to prevent danger of personnel contacting the charged components. In addition, this arrangement also results in a relatively complete and aesthetically pleasing overall structure after the charging assembly 100 and charger 200 are assembled together, which are separate from each other.

In some embodiments of the present disclosure, the connection terminal set 230 of the charger 200 includes a plurality of conductive terminals respectively located in a plurality of recesses. As an example, during the mounting of the charging assembly 100 to the charger 200, the protruding plurality of conductive terminals (e.g., the plurality of conductive pins) of the connection terminal group 130 are inserted into the plurality of concave holes of the connection terminal group 230, respectively, and are in electrical contact with the conductive terminals in the concave holes, thereby completing the electrical connection of the charger 200 to the charging assembly 100. It can be seen that the conductive terminals of the connection terminal group 230 of the charger 200 are charged and directly exposed to the external environment when the charging assembly 100 is not yet mounted to the charger 200. Since the conductive terminals of the connection terminal group 230 may have a charging power to be transmitted exceeding 100W and have a high voltage, the exposed conductive terminals may have a safety hazard. Accordingly, by disposing the conductive terminals of the connection terminal group 230 of the charger 200 in the concave holes, the possibility of a person's finger or other part touching the charging terminals of the charger 200 can be advantageously eliminated, which improves the safety of the charging device 1000.

In some embodiments of the present disclosure, the power conversion circuit 220 is configured to convert input power received from the external power supply 2000 into output power based on the indication signal received from the charging assembly 100. As an example, the control and driving circuit portion 222 of the power conversion circuit 220 may receive the indication signal from the protocol circuit 120 of the charging assembly 100 via the connection terminal group 230 and the connection terminal group 130. The indication signal is determined after the protocol circuit 120 communicates with the device 3000 to be charged. For example, in the event that the protocol circuit 120 determines to match or be compatible with the charging protocol of the device to be charged 3000, the protocol circuit 120 may issue an indication signal to the power conversion circuit 220 indicating a higher charging power, whereas in the event that the protocol circuit 120 determines to not match or be incompatible with the charging protocol of the device to be charged 3000, the protocol circuit 120 may issue an indication signal to the power conversion circuit 220 indicating a lower safe charging power. The power conversion circuit 220 may control and drive, for example, the time at which the switching device in the power supply circuit 221 is turned on and off (e.g., control the duty ratio of the switching device) based on the received indication signal, thereby outputting the power required by the device to be charged 3000.

In embodiments of the present disclosure, the protocol circuitry and port components of the charging device may be provided in a charging assembly separate from the charger, so that the charging assembly may be selected and replaced as desired. In preparation for charging the device to be charged with the charging means, a charging component having a charging protocol matching or compatible with the device to be charged may be selected or replaced. Therefore, the charging device can ensure that the charging protocol of the charging device is matched or compatible with the charging protocol of the equipment to be charged, so that quick charging can be provided for the equipment to be charged, and the charging performance of the charging device is utilized to the greatest extent. In addition, under the condition that the frequently used port component is damaged, the charging assembly can be directly replaced, so that the whole charging device is prevented from being replaced, the service life of the charging device is prolonged, and the maintenance difficulty and the maintenance cost are also reduced.

Many modifications and other embodiments of the disclosure set forth herein will come to mind to one skilled in the art to which this disclosure pertains having the benefit of the teachings presented in the foregoing descriptions and the associated drawings. Therefore, it is to be understood that the embodiments of the disclosure are not to be limited to the specific embodiments disclosed and that modifications and other embodiments are intended to be included within the scope of the disclosure. Furthermore, while the foregoing description and related drawings describe example embodiments in the context of certain example combinations of components and/or functions, it should be appreciated that different combinations of components and/or functions may be provided by alternative embodiments without departing from the scope of the present disclosure. In this regard, for example, other combinations of different components and/or functions than those explicitly described above are also contemplated as being within the scope of the present disclosure. Although specific terms are employed herein, they are used in a generic and descriptive sense only and not for purposes of limitation.
