Description

Technical Field

[0001] The present invention relates to the technical field of chargers, and in particular to a power adapter. Background Art

[0002] Power adapters are devices that change the power supply of small portable electronic devices and electronic appliances. With the development of electronic science and technology and the improvement of social living standards, the application of electronic products is becoming more and more widespread. When traveling or studying outside, you usually need to carry a variety of electronic devices. These electronic devices need to be charged through power adapters. The charging interfaces of different electronic devices are different, and electronic devices such as smart watches can only be charged through wireless chargers.

[0003] There are currently two common types of power adapters on the market: the first type of power adapter is a power adapter that is only provided with a plug for use as a plug. When using this type of power adapter, the user needs to carry a charging cable or wireless charging module that is compatible with their electronic device; the second type of power adapter is an integrated design of plug and charging cable. When the charging port types of different electronic devices of the user are different, the user needs to carry multiple power adapters, and this type of power adapter usually cannot realize the wireless charging function.

[0004] In addition, the existing power adapter cannot adjust the output power of the power adapter according to the number of electronic devices connected to it, which makes it difficult for the existing power adapter to charge and supply power to multiple electronic devices at the same time while ensuring power safety.

[0005] In addition, some existing power adapters use a telescopic component to curl the charging cable, but such power adapters are usually equipped with a single telescopic component, and usually use a single charging cable. This is because after the telescopic component is assembled, it is necessary to control the end of the charging cable with the charging connector to pass through the shell of the power adapter, and a through hole needs to be reserved on the shell for the charging connector to pass through; and the size of the charging connector is usually large, and the size of the reserved through hole will also be large. Once multiple telescopic components are integrated in the shell of the power adapter, multiple through holes need to be reserved on the shell, and ultimately the shell size and thickness of the entire power adapter are very large, which is not conducive to user use and carrying. Summary of the invention

[0006] The technical problem to be solved by the present invention is to provide a new power adapter to solve the problem that the existing power adapter is inconvenient to use.

[0007] In order to solve the above technical problems, the technical solution adopted by the present invention is: a power adapter, which includes a shell and a circuit board arranged in the shell, a charging plug electrically connected to the circuit board is installed on one side of the shell, and at least two telescopic components are also provided in the shell, and the telescopic components are used to telescopically store the charging cable, and the charging cable is electrically connected to the circuit board; wherein, a first through hole and at least one second through hole are opened on the other side of the shell, and the charging cable of one of the telescopic components extends out of the shell from the first through hole and is electrically connected to the wireless charging unit; and a charging cable of at least one of the telescopic components extends out of the shell from the second through hole and is electrically connected to the charging connector.

[0008] In the above technical solution of the present invention, in order to solve the problems existing in the common power adapters on the market: the inability to meet the charging requirements of different devices to be charged and the inconvenience of charging for users, the present invention designs a new power adapter, which can realize wired charging and wireless charging at the same time. The charging connector for wired charging can adopt a suitable connector type according to actual usage requirements to meet the diverse charging needs of users.

[0009] Based on the above design, in actual application, the power adapter can be in the form of a retractable cable, which is convenient for the user to stretch the charging cable, thereby realizing wired charging of one device to be charged using the charging connector, and wireless charging of another device to be charged through the wireless charging unit at the same time.

[0010] It can be seen that by adopting the power adapter designed by the present invention, users no longer need to carry multiple power adapters, which can greatly simplify the user's charging operation and meet the user's diverse charging needs in daily life. It has good promotion prospects and application value.

[0011] Furthermore, the power adapter described in the present invention also includes a card board, which is clamped in the second through hole, and a avoidance groove is provided on one side of the card board. The avoidance groove and the inner wall of the second through hole form a wire outlet hole, and the charging cable extends out of the shell from the wire outlet hole.

[0012] Research has found that once multiple telescopic components are set up in the existing power adapter, the telescopic components need to control the end of the charging cable with the charging connector to pass through the shell of the power adapter after assembly, and the size of the charging connector is usually large, which leads to the need to reserve multiple large-sized through holes on the shell for the charging connector to pass through. This will cause the shell size and thickness of the entire power adapter to be very large, which is not conducive to user use and carrying.

[0013] To this end, in the present invention, a card plate that can be detachably connected to the housing is optimized and designed. The card plate can be specifically arranged in the second through hole, and the avoidance groove on one side of the card plate can be enclosed with the inner wall of the second through hole to form a wire outlet hole. Based on this design, when a telescopic assembly is arranged in the housing, the card plate can be omitted at this time, and one end of the telescopic cable carrying the charging connector can directly pass through the second through hole of large size, and then covered with the card plate to ensure the normal entry and exit of the charging cable based on the above-mentioned wire outlet hole.

[0014] For example, the connector seat of the existing charging connector is usually a flat connector seat (see Figure 1 , Figure 4 As shown in the figure, it is generally in the shape of a rectangular parallelepiped. Once a plurality of telescopic components are provided in an existing power adapter, the width and length of each through hole provided on the shell of the power adapter need to be larger than the size of the flat connector seat, so that the flat connector seat can pass through the shell in a horizontal state facing the through hole. The setting of such a large-sized through hole will inevitably make it difficult to reduce the size of the shell.

[0015] The shell used in the present invention has a second through hole reserved in advance, and the width of the second through hole is relatively small, which is smaller than the width of the flat connector seat, and the length of the second through hole is relatively large. The above-mentioned flat connector seat can be in a vertical state (in the vertical state, only the second through hole is required to meet the length and thickness of the flat connector seat) and pass through the shell with the second through hole, and then install a card plate to use the card plate to reduce the size of the outlet hole. At this time, the width of the outlet hole is consistent with the width of the second through hole, and the length of the outlet hole is smaller than the length of the flat connector seat.

[0016] Therefore, based on the setting of the card board, the problem of the large shell size when the power adapter is provided with multiple telescopic components can be solved. It can reduce the volume of the shell by 50% to a certain extent, thereby facilitating users to carry and use it.

[0017] Furthermore, in the power adapter described in the present invention, a protruding blocking member is provided on the outer peripheral surface of one end of the charging cable extending from the shell.

[0018] In the above technical solution, the blocking member is used to limit and block the retraction stroke of the charging cable during the retraction process of the charging cable, so that when the charging cable is retracted to a preset size, it will not be further retracted due to the telescopic component, thereby facilitating subsequent storage and use.

[0019] Furthermore, in the power adapter described in the present invention, a magnetic member is provided on the inner side surface of the card plate close to the interior of the shell, and a metal shell is sleeved on the charging connector, and the magnetic member is used to adsorb the metal shell on the charging connector.

[0020] In the above technical solution, the shell of the existing power adapter is usually formed by integral injection molding. After the telescopic component in the above shell is installed and the extended length of the charging cable is determined, the magnetic part can be set on the inner wall of the shell. However, at this time, a lot of parts have been set in the shell, and its internal structure is compact and the space is narrow. Usually, it can only be installed manually, which consumes a lot of manpower for assembly. In addition, due to the high difficulty of assembly, it is very easy to have the problem of improper installation of the magnetic part and falling off after installation during long-term use, which leads to subsequent rework and affects production efficiency.

[0021] Unlike existing power adapter products, the power adapter designed by the present invention is provided with a card plate, which can be snap-fitted onto the shell. The manufacturer can directly assemble the magnetic part on the inner side of the card plate close to the inside of the shell by manual assembly or automatic assembly. The installation difficulty is low, the production efficiency is high, and the production failure rate can be greatly reduced.

[0022] Furthermore, in the power adapter described in the present invention, the card plate includes a first vertical portion, a horizontal portion, a bending portion, and a second vertical portion connected in sequence, the first vertical portion and the second vertical portion both extend along a first direction, and the horizontal portion extends along a second direction perpendicular to the first direction; wherein, the second vertical portion is provided with a avoidance groove extending along the second direction and passing through the second vertical portion, and a snap fastener is provided on the inner side surface of the first vertical portion close to the shell.

[0023] Furthermore, in the power adapter described in the present invention, at least two telescopic components are stacked in sequence along the thickness direction of the shell, a limiting groove is provided in the shell, the telescopic component is arranged in the limiting groove, and a positioning protrusion extending along the thickness direction of the shell is provided on the side wall of the limiting groove, and a positioning groove matching the positioning protrusion is provided on the outer wall of the telescopic component.

[0024] In the above technical solution, the possibility of the power adapter loosening from the power socket and falling to the ground during actual use by the user is taken into consideration; in order to improve the reliability and durability of the power adapter, in actual application, a positioning protrusion may be provided on the limit groove of the shell, and a positioning groove may be provided on the outer wall of the telescopic component, so as to enhance the installation stability of the telescopic component in the shell based on the matching relationship between the positioning protrusion and the positioning groove, avoid displacement caused by extreme collision, and prevent affecting the normal use of subsequent users.

[0025] Furthermore, in the power adapter described in the present invention, a first accommodating groove and a second accommodating groove arranged one-to-one corresponding to the second through hole are provided on the other side of the shell, the wireless charging unit is provided in the first accommodating groove, and the charging connector is provided in the second accommodating groove.

[0026] In the above technical solution of the present invention, in actual application, when charging is not needed, the charging cable extending from the first through hole or the second through hole and the components connected thereto can be correspondingly accommodated in the above-mentioned first accommodating groove and the second accommodating groove to improve the storage effect and facilitate subsequent reuse.

[0027] It should be noted that, in practical applications, the first receiving groove can be specifically selected as a notch shape that matches the shape of the wireless charging unit, such as a circular groove; the second receiving groove can also be specifically selected as a notch shape that matches the shape of the charging connector, such as a rectangular groove. When the first receiving groove and the second receiving groove are provided, a spherical edge can be provided at the notch edge of the first receiving groove and the second receiving groove, so that the user's finger can easily extend from the spherical edge into the first receiving groove or the second receiving groove, thereby facilitating the taking and placing of the required charging connector or wireless charging unit.

[0028] Furthermore, in the power adapter described in the present invention, a first telescopic component, a second telescopic component and a third telescopic component are provided in the shell, and a first through hole and two second through holes are opened on the shell; wherein, the charging cable of the first telescopic component extends out of the shell from the first through hole and is electrically connected to the wireless charging unit; the charging cable of the second telescopic component extends out of the shell from one of the second through holes and is electrically connected to the type-C charging connector; the charging cable of the third telescopic component extends out of the shell from another of the second through holes and is electrically connected to the Lightning charging connector.

[0029] Furthermore, in the power adapter described in the present invention, an MCU controller is provided on the circuit board, and a charging protocol storage module is provided in the MCU controller, and a plurality of fast charging protocols are stored in the charging protocol storage module; wherein, when the charging connector is connected to the device to be charged, the MCU controller responds and obtains the fast charging type of the device to be charged, and calls the corresponding fast charging protocol from the charging protocol storage module according to the fast charging type to fast charge the device to be charged.

[0030] In the above technical solution of the present invention, taking into account the possible fast charging needs of the user's device to be charged and improving the user's usage experience, in actual application, a charging protocol storage module can also be set in the MCU controller to pre-store multiple fast charging protocols in the charging protocol storage module, and during actual charging, identify and obtain the corresponding fast charging type, and call the corresponding fast charging protocol from the charging protocol storage module to fast charge the device to be charged.

[0031] It should be noted that, in actual application, the fast charging protocol stored in the charging protocol storage module may include at least one of the following: QC fast charging protocol, PD fast charging protocol, FCP fast charging protocol, AFC fast charging protocol, SFCP fast charging protocol, APPLE fast charging protocol and SUNSUMG fast charging protocol.

[0032] Furthermore, in the power adapter described in the present invention, the MCU controller is used to control the charging power of the charging connector according to the usage status of the wireless charging unit and the charging connector; wherein, when using a single charging connector for charging, the charging power of the charging connector is 30W.

[0033] In the above technical solution of the present invention, the power adapter can provide the MCU controller on the circuit board with real-time judgment on the current usage of the wireless charging unit and the charging connector, and allocate the output power of each power supply end according to the specific usage.

[0034] For example, the power adapter is provided with three telescopic components, and the charging line of one telescopic component extends out of the shell from the first through hole and is electrically connected to the wireless charging unit; the charging lines of the other two telescopic components extend out of the shell from two different second through holes and are electrically connected to the charging connector.

[0035] At this time, when using a power adapter for charging, the following power supply control can be performed according to the usage: (1) When the user only uses the above-mentioned wireless charging unit for charging, the MCU controller detects that the wireless charging unit is working and can specifically control it to output a constant 3W power, that is, the output voltage is 5V and the output current is 0.6A.

[0036] (2) When any of the above charging connectors works alone, the MCU controller detects that a single charging connector is working and can output a constant 30W power to facilitate users to fast charge devices such as laptops.

[0037] (3) When the user uses the above-mentioned wireless charging unit in conjunction with a charging connector to work simultaneously, the MCU controller detects that a wireless charging unit and a charging connector are working, and it can output a constant 33W power. At this time, the output voltage of the wireless charging unit is 5V, the output current is 0.6A, and the output power is 3W; the output power of the charging connector is 30W.

[0038] (4) When the user uses two charging connectors to work at the same time, the MCU controller detects that the two charging connectors are working and can output a constant 15W power. At this time, the output voltage of the two charging connectors is 5V and the output current is 3A.

[0039] (5) When the user uses the above wireless charging unit with two charging connectors to work at the same time, the MCU controller detects that one wireless charging unit and two charging connectors are working, and it can output a constant 15.5 power. At this time, the output voltage of the wireless charging unit is 5V, the output current is 0.6A, and the output power is 3W; the output voltage of the two charging connectors is 5V, and the output current is 2.5A.

[0040] It should be noted that the existing power adapters designed with multiple charging cables do not have the power distribution problem of the power adapter of the present invention, and the output power of each charging cable is constant and low. The power adapter designed by the present invention can reasonably adjust the power distribution, which can greatly improve the safety of the power adapter, and when using a single charging connector for charging, the charging power of the charging connector can be controlled to reach 30W, meeting the high-power charging requirements of devices such as laptops.

[0041] The beneficial effects of the present invention are as follows: the present invention designs a new power adapter, which can integrate multiple telescopic components at the same time, so as to retract and store the charging cable based on the telescopic components, so as to charge the components to be charged using the charging cables set on the multiple telescopic components. The user can stretch the charging cable, so as to simultaneously realize wired charging of one device to be charged using the charging connector, and wireless charging of another device to be charged through the wireless charging unit; for example: the user can plug the power adapter into the power socket, and pull out a charging cable extending from the first through hole to extend the extension size of the charging cable, and place the smart watch on the wireless charging unit connected to the charging cable for charging; at the same time, the user can pull out another charging cable extending from the second through hole to plug and charge the mobile phone with the charging connector connected to the charging cable, which can greatly meet the diverse charging needs of users in daily life, and has good promotion prospects and application value.

[0051] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following is an explanation in combination with the implementation modes and the accompanying drawings.

[0052] like Figure 1-Figure 9 As shown, in this embodiment, the present invention designs a new power adapter, which includes a shell 1 and a circuit board 13 arranged in the shell 1, a charging plug 3 electrically connected to the circuit board 13 is installed on one side of the shell 1, and a third accommodating groove 18 is specifically provided on one side of the shell 1, the charging plug 3 is rotatably arranged in the third accommodating groove 18, and the charging plug 3 is electrically connected to the circuit board 13 to supply power to the circuit board 13.

[0053] In the present invention, considering the problem that the charging cable 21 of the power adapter with a fixed cable length is inconvenient to store in actual use, a telescopic component 2 is specifically provided in the housing 1 of the power adapter, and the telescopic component 2 is used to telescopically store the charging cable 21. The charging cable 21 is electrically connected to the circuit board 13, and one end of the charging cable 21 can extend from the housing 1 and be electrically connected to the wireless charging unit 4 or the charging connector 6. Among them, the telescopic component 2 is a content that can be clearly understood by those skilled in the art based on the existing technical solutions, and will not be described in detail here.

[0054] It should be noted that if Figure 3 As shown, in the present embodiment, three telescopic components 2 are specifically arranged in the shell 1, namely the first telescopic component, the second telescopic component and the third telescopic component, and the three telescopic components 2 are sequentially stacked along the thickness direction of the shell 1, and a limiting groove 14 is provided in the shell 1, and the above three telescopic components 2 are all arranged in the limiting groove 14, and the side wall of the above limiting groove 14 is provided with a positioning protrusion 15 extending along the thickness direction of the shell 1, and the outer wall of the above telescopic component 2 is provided with a positioning groove 22 matching the positioning protrusion 15, so as to enhance the installation stability of the telescopic component 2 in the shell 1 based on the matching relationship between the positioning protrusion 15 and the positioning groove 22, avoid displacement caused by extreme collision, and prevent affecting the normal use of subsequent users.

[0055] Accordingly, see Figure 1 , Figure 2 as well as Figure 6 As shown, in this embodiment, a first through hole 11 and another second through hole 12 are opened on the other side of the shell 1, and the arrangement order along the thickness direction of the shell 1 is: second through hole 12, first through hole 11 and second through hole 12.

[0056] In this embodiment, the charging cable 21 of the first telescopic component can extend out of the shell 1 from the first through hole 11 and be electrically connected to the wireless charging unit 4; the charging cable 21 of the second telescopic component extends out of the shell 1 from a second through hole 12 and is electrically connected to the type-C charging connector 6; the charging cable 21 of the third telescopic component extends out of the shell 1 from another second through hole 12 and is electrically connected to the Lightning charging connector 6.

[0057] It can be seen that the power adapter designed by the present invention can realize wired charging and wireless charging at the same time, and the charging connector 6 for wired charging can adopt a suitable connector form according to actual use requirements to meet the diverse charging needs of users. In actual application, the power adapter can be in the form of a retractable cable, which is convenient for users to stretch the charging cable 21, so as to realize wired charging of one or more devices to be charged by using the charging connector 6, and wireless charging of one device to be charged by the wireless charging unit 4 at the same time.

[0058] Accordingly, the inventors have found that once a plurality of telescopic components 2 are provided in the existing power adapter, the shell 1 of the entire power adapter will have a problem of being very thick.

[0059] For this reason, Figure 1 and Figure 8 As shown, in the present invention, a card plate 5 that can be detachably connected to the housing 1 is optimized and designed. The card plate 5 can be specifically clamped in the second through hole 12, and a side of the card plate 5 is provided with an avoidance groove 55. The avoidance groove 55 and the inner wall of the second through hole 12 are combined to form an outlet hole 7, so that the charging line 21 can extend out of the housing 1 of the power adapter from the outlet hole 7. Based on this design, when the telescopic component 2 is provided in the housing 1, the card plate 5 can be omitted at this time, and one end of the telescopic line carrying the charging connector 6 can directly pass through the large-sized second through hole 12, and then the card plate 5 is covered to ensure the normal entry and exit of the charging line 21 based on the outlet hole 7.

[0060] For example: the connector seat of the existing charging connector 6 is usually a flat connector seat, which is generally in the shape of a rectangular parallelepiped. Once the existing power adapter is provided with multiple telescopic components 2, the width and length dimensions of each through hole opened on the shell 1 of the power adapter need to be larger than the size of the flat connector seat, so that the above-mentioned flat connector seat can pass through the shell 1 in a horizontal state facing the through hole. The setting of such a large-sized through hole will inevitably make it difficult to reduce the size of the shell 1.

[0061] The shell 1 used in the present invention has a second through hole 12 reserved in advance. The width of the second through hole 12 is relatively small, which is smaller than the width of the flat connector seat, and the length of the second through hole 12 is relatively large. The above-mentioned flat connector seat can be in a vertical state (in the vertical state, only the second through hole 12 is required to meet the length and thickness of the flat connector seat) and then the second through hole 12 passes through the shell 1, and then the card plate 5 is installed to use the card plate 5 to reduce the size of the outlet hole 7. At this time, the width of the outlet hole 7 is consistent with the width of the second through hole 12, and the length of the outlet hole 7 is smaller than the length of the flat connector seat.

[0062] Therefore, based on the setting of the card board 5, the problem of the large size of the shell 1 when the power adapter is provided with multiple telescopic components 2 can be effectively solved. It can reduce the volume of the shell 1 by 50% to a certain extent, thereby facilitating the user to carry and use it.

[0063] Accordingly, if Figure 4 As shown, in actual application, in order to facilitate the use of the user, in this embodiment, a protruding blocking member 8 is also provided on the outer peripheral surface of one end of the charging line 21 of the three telescopic components 2 extending from the housing 1. The blocking member 8 is used to limit the retraction stroke of the charging line 21 during the retraction process of the charging line 21, so that when the charging line 21 is retracted to a preset size, it will not be further retracted due to the telescopic component 2, thereby facilitating subsequent storage and use.

[0064] See also Figure 8 and Fig. 9 In this embodiment, a magnetic member 9 is provided on the inner side surface of the power adapter close to the inner side of the housing 1, and a metal shell is provided on the charging connector 6, and the magnetic member 9 is used to adsorb the metal shell on the charging connector 6; wherein, in this embodiment, the card plate 5 includes a first vertical portion 51, a horizontal portion 52, a bending portion 53, and a second vertical portion 54 connected in sequence, and the first vertical portion 51 and the second vertical portion 54 are both along the first direction ( Figure 8 The horizontal portion 52 extends in a second direction ( Figure 8 The second vertical portion 54 is provided with an avoidance groove 55 extending along the second direction and penetrating the second vertical portion 54, and a buckle 56 is provided on the inner side of the first vertical portion 51 close to the housing 1. The card plate 5 is overlapped with the inner wall of the housing 1 based on the second vertical portion 54, and is buckled with the second through hole 12 of the housing 1 by the buckle 56; in order to avoid the charging line 21, the second vertical portion 54 is also provided with an avoidance groove 55 to improve the wire outlet effect and make the wire outlet process smoother and unobstructed.

[0065] Accordingly, in this embodiment, in order to facilitate the accommodation of the charging connector 6 and the wireless charging unit 4, in the power adapter, the other side of the housing 1 is provided with a first accommodation groove 16 and two second accommodation grooves 17 corresponding to the second through holes 12, the wireless charging unit 4 is arranged in the first accommodation groove 16, and the charging connector 6 is arranged in the second accommodation groove 17. When charging is not needed, the charging line 21 extending from the first through hole 11 or the second through hole 12 and the components connected thereto can be correspondingly accommodated in the first accommodation groove 16 and the second accommodation groove 17 to improve the storage effect and facilitate subsequent reuse.

[0066] It should be pointed out that if Figure 5 and Figure 6 As shown, in actual application, the first receiving groove 16 can be specifically selected as a notch shape matching the shape of the wireless charging unit 4, such as a circular groove; the second receiving groove 17 can also be specifically selected as a notch shape matching the shape of the charging connector 6, such as a rectangular groove. When the first receiving groove 16 and the second receiving groove 17 are provided, a spherical edge can be provided at the notch edge of the first receiving groove 16 and the second receiving groove 17, so that the user's finger can easily extend from the spherical edge into the first receiving groove 16 or the second receiving groove 17, so as to facilitate the taking and placing of the required charging connector 6 or the wireless charging unit 4.

[0067] In addition, in the power adapter described in the present invention, an MCU controller is provided on the above-mentioned circuit board 13, and a charging protocol storage module is provided in the MCU controller, and a plurality of fast charging protocols are stored in the charging protocol storage module; wherein, when the above-mentioned charging connector 6 is connected to the device to be charged, the above-mentioned MCU controller responds and obtains the fast charging type of the device to be charged, and calls the corresponding fast charging protocol from the charging protocol storage module according to the fast charging type to fast charge the device to be charged.

[0068] In this embodiment, the fast charging protocol stored in the charging protocol storage module may include at least one of the following: QC fast charging protocol, PD fast charging protocol, FCP fast charging protocol, AFC fast charging protocol, SFCP fast charging protocol, APPLE fast charging protocol and SUNSUMG fast charging protocol.

[0069] In the above technical solution of the present invention, the power adapter can provide the MCU controller on the circuit board 13 with real-time judgment of the current usage of the wireless charging unit 4 and the charging connector 6, and allocate the output power of each power supply end according to the specific usage, as shown in Table 1 below: Table 1 lists the usage conditions and output power relationships of the charging cables 21 of the first telescopic assembly, the second telescopic assembly, and the third telescopic assembly of the power adapter of the present invention when supplying power respectively.

[0070] Table 1.

[0071] It can be seen from Table 1 above that in this embodiment, when a power adapter is used for charging, the following power supply control can be performed according to the usage situation: (1) When the user only uses the above-mentioned wireless charging unit 4 for charging, the MCU controller detects that the wireless charging unit 4 is working and can specifically control it to output a constant 3W power, that is, the output voltage is 5V and the output current is 0.6A.
