Description

Technical Field

[0001] This application relates to the technical field of charging, and more particularly, to a charger. Background Art

[0002] A charger generally refers to a static current conversion device that uses power semiconductor devices to convert alternating current with a fixed voltage and frequency into direct current.

[0003] In the related art, there is a charger with a single output port. However, there are multiple output ports on this charger. If external devices are inserted into all the output ports, the charger may short-circuit because it needs to charge multiple external devices simultaneously, resulting in a decrease in the charging safety of the charger. Summary of the Utility Model

[0004] An embodiment of this application provides a charger, aiming to ensure the charging safety of the charger while making it small in size.

[0005] An embodiment of this application provides a charger, which includes a housing, a power supply module, at least two output interfaces, and a shielding structure. The power supply module is disposed inside the housing. At least two output interfaces are all connected to the housing. The output interfaces are connected in parallel with each other, and each output interface is electrically connected to the power supply module. When any one of the output interfaces is connected to an external device, the power supply module charges the external device through the output interface connected to the external device. The shielding structure is connected to the housing, and when any one of the output interfaces is connected to an external device, the shielding structure shields the remaining output interfaces.

[0006] The charger of the embodiment of this application has at least two beneficial effects:

[0007] First, the charger is small in size and low in cost. In the embodiment of this application, only one set of power supply module is needed to be compatible with at least two output interfaces, making the charger small in size and low in cost.

[0008] Second, the charging safety of the charger is ensured. In the embodiment of this application, by setting the shielding structure, when any one of the output interfaces is connected to an external device, the remaining output interfaces need to be shielded by the shielding structure. That is, when one output interface is connected to an external device for charging, by setting the shielding structure, the remaining output interfaces cannot be connected to other external devices, preventing users from inserting the output interfaces incorrectly; or preventing users from inserting multiple charging cables into the output interfaces simultaneously, which may cause problems such as short-circuit of the charger and excessive current on the power supply module, thus ensuring the charging safety of the charger.

[0019] In order to make the purpose, technical solutions and advantages of the present application clearer, the following further details the present application in combination with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0020] Please refer to Figures 1 - 3 , an embodiment of the present application provides a charger 1, which is a device for charging an external device 50. There are various types of chargers 1. Exemplarily, the charger 1 can be a universal serial bus charger, a wireless charger, a portable charger, a car charger, a solar charger, etc.

[0021] Please continue to refer to Figures 1 - 3 , further, the charger 1 includes a housing 10, a power supply module 20, at least two output interfaces 30, and a shielding structure 40.

[0022] The housing 10 is usually made of plastic material, and the plastic material is mainly made of plastic materials such as polycarbonate, polystyrene, polypropylene, polyethylene, and polyvinyl chloride. The above materials all have good mechanical strength, stability, hardness, and weather resistance.

[0023] The power supply module 20 is disposed in the housing 10. That is, the housing 10 plays a protective role for the power supply module 20 to prevent the components in the power supply module 20 from being exposed to the air.

[0024] The output interfaces 30 are all connected to the housing 10. The number of output interfaces 30 is more than two. The output interfaces 30 are connected in parallel with each other and are all electrically connected to the power supply module 20. When any output interface 30 is connected to an external device 50, the power supply module 20 charges the external device 50 through the output interface connected to the external device 50.

[0025] It should be noted that the external device 50 can be a device that needs to be charged, such as a mobile phone, a tablet computer, and a laptop computer. The embodiments of the present application do not make specific limitations thereto. The output interface 30 can include at least one of a USB-A output interface, a USB-C output interface, a Lightning output interface, and a MicroUSB output interface. The embodiments of the present application do not make specific limitations thereto either.

[0026] It should be noted that when the output interface 30 is connected to multiple external devices 50, the power supply module 20 stops charging the external device 50 to improve the charging safety of the charger 1.

[0027] Please refer to Figure 4 , therefore, the charger 1 of the embodiment of the present application is provided with a shielding structure 40 to prevent the output interface 30 from being connected to multiple external devices 50 at the same time.

[0028] Specifically, the shielding structure 40 is connected to the housing 10. When any output interface 30 is connected to an external device 50, the shielding structure 40 can shield the remaining output interfaces 30. It can be understood that when the charger 1 includes at least two or more output interfaces 30, and any output interface 30 is connected to an external device 50, the remaining output interfaces 30 cannot be connected to other external devices 50. Therefore, by providing the shielding structure 40 on the charger 1, when any output interface 30 is connected to an external device 50, the remaining output interfaces 30 need to be shielded by the shielding structure 40 to form a foolproof design, thereby preventing the user from inserting the output interface 30 incorrectly; or preventing the user from inserting multiple charging cables into the output interface 30 at the same time, which may cause unsafe problems such as short circuit of the charger 1 and excessive current on the power supply module 20.

[0029] Furthermore, compared with the prior art where the charger 1 needs to be provided with two sets of power supply modules 20 at the same time, the charger 1 in the embodiment of the present application can be compatible with at least two output interfaces 30 by using one set of power supply modules 20. That is, when an additional output interface 30 is added to the charger 1, the technician only needs to add a charging protocol program corresponding to the output interface 30 to the power supply module 20. In this way, the small size and low cost of the charger 1 can be satisfied.

[0030] The charger 1 in the embodiment of the present application has at least two beneficial effects:

[0031] First, the charger 1 has a small size and low cost. The embodiment of the present application only needs to use one set of power supply modules 20 to be compatible with at least two output interfaces 30, so that the charger 1 has a small size and low cost.

[0032] Second, the charging safety of the charger 1 is ensured. In the embodiment of the present application, by providing the shielding structure 40, when any output interface 30 is connected to an external device 50, the remaining output interfaces 30 need to be shielded by the shielding structure 40. That is, when one output interface 30 is connected to an external device 50 for charging, by providing the shielding structure 40, the remaining output interfaces 30 cannot be connected to the remaining external devices 50, so as to prevent the user from inserting the output interface 30 incorrectly; or preventing the user from inserting multiple charging cables into the output interface 30 at the same time, which may cause unsafe problems such as short circuit of the charger 1 and excessive current on the power supply module 20, thereby ensuring the charging safety of the charger 1.

[0033] Please refer to Figure 2, in some embodiments, the interface types of any two output interfaces 30 are different. It can be understood that the charger 1 may include at least two or more output interfaces 30, and the interface types of any two output interfaces 30 may be different. In this case, the charger 1 can be adapted to various types of external devices 50, so as to avoid the situation where a charger 1 can only be adapted to an external device 50 of one type. That is, the user does not need to purchase a new charger 1 in order to adapt to the interface of the charging cable. Thus, the cost of purchasing materials for the user can be saved. And the interface types of any two output interfaces 30 are different, so that the charger 1 can be adapted to different types of external devices 50.

[0034] Please refer to Figure 1 , in some embodiments, the power supply module 20 includes an AC-DC conversion module 21, a protocol chip 22, a buck-boost module 23, and a switch module 24. The AC-DC conversion module 21 is disposed in the housing 10, and the AC-DC conversion module 21 is electrically connected to the mains power to convert the input AC voltage into a stable DC voltage. Among them, the common mains power is 90 volts to 264 volts. The protocol chip 22, the buck-boost module 23, and the switch module 24 are all disposed in the housing 10, and the AC-DC conversion module 21 can supply power to the protocol chip 22, the buck-boost module 23, and the switch module 24.

[0035] Further, the protocol chip 22 refers to a module integrating a logic control circuit and a charging protocol program, etc. Among them, the charging protocols supported by the protocol chip 22 include at least one of the USB PD (Power Delivery) charging protocol, the QC (Quick Charge) charging protocol, the FCP (Fast Charge Protocol) protocol, the SCP (Super Charge Protocol) protocol, and the Mi Turbo Charge protocol; of course, the charging protocols supported by the protocol chip 22 do not only include the charging protocols mentioned above, and the embodiments of the present application do not make specific limitations in this regard. The buck-boost module 23 refers to a module for adjusting the output voltage.

[0036] Specifically, both the protocol chip 22 and the buck-boost module 23 are electrically connected to the AC-DC conversion module 21, so that the AC-DC conversion module 21 charges the protocol chip 22 and the buck-boost module 23; the switch module 24 is electrically connected to both the output interface 30 and the buck-boost module 23, and the switch module 24 also realizes bidirectional signal communication with the protocol chip 22; the output interface 30 can realize signal communication with both the external device 50 and the protocol chip 22 (as Figure 1 shown, the solid line is an electrical connection, and the dashed line is a signal communication connection).

[0037] Specific working principle of charger 1: The AC-DC conversion module 21 converts the AC mains power into a stable DC power supply to supply power to the protocol chip 22, the buck-boost module 23, and the switching module 24. When an external device 50 is inserted into any output interface 30, at this time, the protocol chip 22 communicates with the external device 50 through the output interface 30, so that the protocol chip 22 recognizes that the external device 50 is connected to any output interface 30. The protocol chip 22 controls the buck-boost module 23 to adjust the output voltage, so that the buck-boost module 23 adjusts the output voltage corresponding to the external device 50. And because the switching module 24 and the protocol chip 22 realize bidirectional signal communication, the protocol chip 22 can control the switching module 24 to conduct. That is, after the protocol chip 22 recognizes that the output voltage of the buck-boost module 23 conforms to the charging protocol of the external device 50, the protocol chip 22 controls the switching module 24 to conduct, so that the charger 1 can charge the external device 50.

[0038] It should be noted that the switching module 24 may include a switching element (not shown in the figure), or the switching module 24 may include multiple switching elements. The embodiment of the present application does not specifically limit the number of switching elements.

[0039] Exemplarily, when the switching module 24 may include a switching element, an external device 50 is connected to any output interface 30, and after the protocol chip 22 recognizes that the output voltage of the buck-boost module 23 conforms to the charging protocol of the external device 50, at this time, the protocol chip 22 will control the corresponding switching element to conduct, so that the charger 1 can charge the external device 50.

[0040] Exemplarily, when the switching module 24 may include multiple switching elements, the number of switching elements may correspond to the number of output interfaces 30. That is, one switching element is electrically connected to one output interface 30. An external device 50 is inserted into any output interface 30, and the protocol chip 22 recognizes that the output voltage of the buck-boost module 23 conforms to the charging protocol of the external device 50. The protocol chip 22 can control the switching element corresponding to the output interface 30 connected to the external device 50 to conduct, so as to facilitate the charger 1 to charge the external device 50.

[0041] Furthermore, when the protocol chip 22 controls the corresponding switching element to conduct, the protocol chip 22 also controls the remaining switching elements to turn off, so that the charger 1 cannot charge the external device 50 through the remaining output interfaces 30, so as to reduce the probability of problems such as short circuit of the charger 1 and excessive current on the power supply module 20, thereby ensuring the charging safety of the charger 1.

[0042] In other embodiments, when multiple external devices 50 are connected to the output interface 30 simultaneously, the protocol chip 22 communicates with the external devices 50 through the output interface 30 to identify that multiple external devices 50 are connected to the output interface 30 at this time. At this time, the protocol chip 22 will control one or more switching elements to turn off simultaneously, so that the charger 1 cannot charge multiple external devices 50 at the same time, thereby ensuring the charging safety of the charger 1.

[0043] It should be noted that the number of switching elements corresponds to the number of buck-boost modules 23. That is, one switching element is electrically connected to one buck-boost module 23. After the protocol chip 22 recognizes that the output voltage of the buck-boost module 23 conforms to the charging protocol of the external device 50, the protocol chip 22 can control the corresponding switching element to conduct, so as to facilitate the charger 1 to charge the external device 50.

[0044] The switching element can be a MOS transistor (Metal-Oxide-Semiconductor), a bipolar junction transistor (BJT), a relay, or other devices or circuits with a switching function. The embodiments of the present application do not make specific limitations on this.

[0045] It should be noted that in some other embodiments, the DC-DC conversion module 22 includes a protocol chip 22, a boost module, and a switching module 24; in some other embodiments, the DC-DC conversion module 22 includes a protocol chip 22, a buck module, and a switching module 24.

[0046] Please refer to Figures 2 - 4 , in some embodiments, the shielding structure 40 includes a shielding member 41. The shielding member 41 is connected to the housing 10, and the shielding member 41 can move relative to the housing 10. It can be understood that the user can move the shielding member 41 by rotating or sliding, so that any output interface 30 is exposed. That is, any output interface 30 is connected to an external device 50, and the shielding member 41 shields the remaining output interfaces 30, so that the remaining external devices 50 cannot be inserted into the remaining output interfaces 30. That is, when any output interface 30 charges an external device 50, the remaining output interfaces 30 cannot charge the remaining external devices 50. In this way, on the one hand, the charger 1 only charges one external device 50 to achieve fast charging of the external device 50 by the charger 1; on the other hand, the shielding member 41 shields the remaining output interfaces 30 to prevent the user from inserting the remaining external devices 50 into the remaining output interfaces 30, thereby improving the charging safety of the charger 1.

[0047] It should be noted that the movement mode of the shielding member 41 relative to the housing 10 in the embodiments of the present application is not limited to only rotation or sliding, and can also be other movement modes that can achieve the movement of the shielding member 41 relative to the housing 10. The embodiments of the present application do not make specific limitations in this regard.

[0048] Please refer to Figures 3 - 5 , in some embodiments, the shielding member 41 may include a shielding portion 411. It can be understood that since the output interface 30 is exposed on the outer surface of the housing 10, when any output interface 30 is connected to an external device 50, the user can operate the shielding portion 411 so that the shielding portion 411 can be slidably arranged on the outer surface of the housing 10, and the shielding portion 411 is spaced from the output interface 30. Further, it is convenient for the shielding portion 411 to shield the remaining output interfaces 30. The user inserts the remaining external devices 50 into the remaining output interfaces 30. In this way, the charging safety of the charger 1 is improved.

[0049] Please refer to Figures 2 - 3 , further, the housing 10 includes a slideway 10a. The slideway 10a can be arranged on the outer surface of the housing 10, and the slideway 10a can be a straight groove slideway or a circular groove slideway. The embodiments of the present application do not make specific limitations in this regard. The following takes the slideway 10a as a straight groove slideway as an example for description.

[0050] Further, the shielding member 41 further includes a connecting portion 412 and an operating portion 413. One end of the connecting portion 412 is connected to the shielding portion 411, and the other end of the connecting portion 412 is connected to the operating portion 413. Among them, the connecting portion 412 can be exposed on the outer surface of the housing 10, or the connecting portion 412 can be arranged inside the housing 10. The embodiments of the present application do not make specific limitations in this regard. The operating portion 413 is connected to the other end of the connecting portion 412, and the operating portion 413 is exposed through the slideway 10a. That is, one side of the operating portion 413 faces the slideway 10a so that the operating portion 413 is installed in the slideway 10a; the other side of the operating portion 413 is away from the slideway 10a and is exposed outside the slideway 10a for the convenience of user operation. That is, the user places the hand on the operating portion 413 or the shielding portion 411, and the user controls the operating portion 413 or the shielding portion 411. At this time, the operating portion 413 slides on the movement track of the slideway 10a so that the operating portion 413 drives the shielding portion 411 and the connecting portion 412 to slide, thereby realizing the shielding of the output interface 30 by the shielding portion 411.

[0051] It should be noted that there are various ways to achieve a sliding connection between the operation part 413 and the slideway 10a, and the embodiments of the present application do not make specific limitations in this regard. Exemplarily, balls can be installed on the surface of the operation part 413 facing the slideway 10a, and the balls are installed in the slideway 10a so that the operation part 413 can move relative to the slideway 10a; alternatively, the operation part 413 is provided with a slide rail matching the slideway 10a, and the cooperation between the slide rail and the slideway 10a is used to achieve the movement of the operation part 413 relative to the slideway 10a.

[0052] In some embodiments, the shielding part 411 is provided with a first through hole 411a. The user can slide the shielding part 411 so that the first through hole 411a coincides with any one of the output interfaces 30. That is, any one of the output interfaces 30 is exposed on the outer surface of the charger 1 through the first through hole 411a, facilitating the insertion of the external device 50 into the exposed output interface 30. At this time, only any one of the output interfaces 30 can be connected to the external device 50 by the user, and the remaining output interfaces 30 are shielded by the shielding part 411. In this way, the user is prevented from inserting the wrong output interface 30.

[0053] Please refer to Figure 2 , in some embodiments, the output interface 30 may include a first output interface 31 and a second output interface 32, and the interface types of the first output interface 31 and the second output interface 32 are different. At this time, the charger 1 has output interfaces 30 of two interface types for the user to choose from, and the user does not need to buy a new charger 1 to match the wire. In this way, the cost of the user purchasing materials is saved.

[0054] It should be noted that the first output interface 31 is a USB-A output interface, and the protocol chip 22 can be used to identify the insertion or removal state of the external device 50 on the USB-A output interface; the second output interface 32 is a USB-C output interface, and the protocol chip 22 can be used to identify the insertion or removal state of the external device 50 on the USB-C output interface. Of course, the first output interface 31 and the second output interface 32 can also be other interface types.

[0055] Please refer to Figure 3, Further, the shielding portion 411 is provided with a first through hole 411a and a second through hole 411b. Among them, by sliding the shielding portion 411, the first through hole 411a can coincide with the first output interface 31, that is, the first output interface 31 is exposed on the outer surface of the charger 1 through the first through hole 411a, so as to facilitate the insertion of the external device 50 into the first output interface 31, while the second through hole 411b is arranged in a dislocation manner with the second output interface 32, so that the shielding portion 411 shields the second output interface 32; or, by sliding the shielding portion 411, the second through hole 411b can coincide with the second output interface 32, that is, the second output interface 32 is exposed on the outer surface of the charger 1 through the second through hole 411b, so as to facilitate the insertion of the external device 50 into the second output interface 32, while the first through hole 411a is arranged in a dislocation manner with the first output interface 31, so that the shielding portion 411 shields the first output interface 31.

[0056] Exemplarily, when the first output interface 31 is connected to the external device 50, the second output interface 32 is shielded by the shielding portion 411, so that the second output interface 32 cannot be connected to the external device 50. In this way, on the one hand, fast charging of the external device 50 by the charger 1 can be realized; on the other hand, the charging safety of the charger 1 is improved.

[0057] Please refer to Figures 4 - 5 , It should be noted that when the first output interface 31 and the second output interface 32 are arranged at intervals from the slideway 10a, at this time, the slideway 10a extends along the length direction of the housing 10. When the user slides the operation portion 413 and moves the operation portion 413 to one end of the slideway 10a, the first through hole 411a coincides with the first output interface 31 (as Figure 4 shown); when the user slides the operation portion 413 and moves the operation portion 413 to the other end of the slideway 10a, the second through hole 411b coincides with the second output interface 32 (as Figure 5 shown); since the shielding portion 411 is provided with the first through hole 411a and the second through hole 411b arranged at intervals, the travel of the operation portion 413 on the slideway 10a is shortened, thereby increasing the movement speed of the shielding structure 40 relative to the housing 10.

[0058] In another embodiment, the output interface 30 may include a first output interface 31, a second output interface 32, and a third output interface (not shown in the figure), and the shielding member 41 is provided with a first through hole 411a, a second through hole 411b, and a third through hole (not shown in the figure).

[0059] Specifically, by sliding the shielding portion 411, the first through hole 411a is aligned with the first output interface 31, that is, the first output interface 31 is exposed on the outer surface of the charger 1 through the first through hole 411a, so as to facilitate the insertion of the external device 50 into the first output interface 31, while the second through hole 411b is misaligned with the second output interface 32, and the third through hole is misaligned with the third output interface, so that the shielding portion 411 shields the second output interface 32 and the third output interface; or, by sliding the shielding portion 411, the second through hole 411b is aligned with the second output interface 32, that is, the second output interface 32 is exposed on the outer surface of the charger 1 through the second through hole 411b, so as to facilitate the insertion of the external device 50 into the second output interface 32, while the first through hole 411a is misaligned with the first output interface 31, and the third through hole is misaligned with the third output interface, so that the shielding portion 411 shields the first output interface 31 and the third output interface; or, by sliding the shielding portion 411, the third through hole is aligned with the third output interface, that is, the third output interface is exposed on the outer surface of the charger 1 through the third through hole, so as to facilitate the insertion of the external device 50 into the third output interface, while the first through hole 411a is misaligned with the first output interface 31, and the second through hole 411b is misaligned with the second output interface 32, so that the shielding portion 411 shields the first output interface 31 and the second output interface 32.

[0060] It should be noted that the interface types of the first output interface 31, the second output interface 32, and the third output interface may be the same or different, and the embodiments of the present application do not make specific limitations in this regard.

[0061] Please continue to refer to Figures 4 - 5 Further, in some embodiments, the shape of the first output interface 31 is adapted to the shape of the first through hole 411a, or the shape of the second output interface 32 is adapted to the shape of the second through hole 411b, or while the shape of the first output interface 31 is adapted to the shape of the first through hole 411a, the shape of the second output interface 32 is also adapted to the shape of the second through hole 411b. The embodiments of the present application do not make specific limitations in this regard.

[0062] Exemplarily, while the shape of the first output interface 31 is adapted to the shape of the first through hole 411a, the shape of the second output interface 32 is also adapted to the shape of the second through hole 411b. In this way, the accuracy of inserting the external device 50 into the first output interface 31 or the second output interface 32 is improved.

[0063] Please refer to Figure 6, in some embodiments, the output interfaces 30 are arranged adjacent to each other. When an external device 50 is connected to any one of the output interfaces 30, the orthographic projection of the interface end of the external device 50 on the surface of the housing 10 where the output interface 30 is located at least partially overlaps with the remaining output interfaces 30, so as to form an occlusion structure 40. It can be understood that, according to the insulation characteristics of the charging cable, since at least a part of the projection of the interface end of the external device 50 overlaps with the remaining output interfaces 30, when any one of the output interfaces 30 is connected to the external device 50, a part of the remaining output interfaces 30 is blocked by the interface of the external device 50, so that the remaining output interfaces 30 cannot be connected to the remaining external devices 50. In this way, physical anti-misconnection can be formed to prevent multiple output interfaces 30 from being used simultaneously and thus prevent any one of the output interfaces 30 from fast charging the external device 50.

[0064] Exemplarily, when the number of the output interfaces 30 is multiple, any one of the output interfaces 30 is exposed on the outer surface of the housing 10, and the remaining output interfaces 30 are arranged around any one of the output interfaces 30. After any one of the output interfaces 30 is connected to the external device 50, the orthographic projection of the interface end of the external device 50 on the surface of the housing 10 where any one of the output interfaces 30 is located coincides with the remaining output interfaces 30. In this way, the remaining output interfaces 30 cannot be connected to the remaining external devices 50.

[0065] Please refer to Figures 7 - 8 , further, in some embodiments, the output interface 30 includes a first output interface 31 and a second output interface 32. Specifically, since the first output interface 31 and the second output interface 32 are arranged adjacent to each other, when the first output interface 31 is connected to the external device 50, the orthographic projection of the interface end of the external device 50 on the surface of the housing 10 where the first output interface 31 is located blocks a part of the second output interface 32, so that the remaining external devices 50 cannot be inserted into the second output interface 32 (as shown in Figure 7 ); conversely, when the second output interface 32 is connected to the external device 50, the orthographic projection of the interface end of the external device 50 on the surface of the housing 10 where the second output interface 32 is located blocks a part of the first output interface 31, so that the remaining external devices 50 cannot be inserted into the first output interface 31 (as shown in Figure 8 ). At this time, the external devices 50 connected to the first output interface 31 and the second output interface 32 are external devices 50 of different types. That is, by arranging the first output interface 31 and the second output interface 32 adjacent to each other to form physical anti-misconnection, and further preventing the first output interface 31 and the second output interface 32 from being used simultaneously. In this way, the charging safety of the charger 1 can be improved.
