[0022] Analysis revealed that there are numerous types of portable electronic devices on the market, each with different charger interfaces and charging protocols. Different portable electronic devices typically come with dedicated chargers, and these chargers vary significantly in output power. Some chargers are extremely slow, often taking several hours to fully charge, which is highly inconvenient for users with fast-paced lifestyles. For example, even different models of the same brand of phone may not have compatible chargers. If a charger is damaged, a new, compatible charger must be purchased to achieve "fast charging," increasing costs and wasting resources. Furthermore, current chargers usually only have one USB port, preventing multiple electronic devices from charging simultaneously. With the rise of wireless charging technology, wired chargers also cannot charge non-wireless charging electronic devices.

[0023] To address the aforementioned issues, this utility model provides a multi-functional charger. By adjusting the output voltage and current, the multi-functional charger can charge electronic devices with various charging protocol standards, thus offering greater applicability. Furthermore, it features multiple output ports, enabling simultaneous charging of multiple electronic devices. The addition of a wireless charging coil and support frame further enhances the charger's adaptability to different usage scenarios, improves the stability of wireless charging, and extends the lifespan of the wireless charging coil.

[0028] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0029] refer to Figures 1 to 5 This utility model provides a multifunctional charger, comprising: a housing having multiple sides and a top surface 100 and a bottom surface arranged opposite to each other; multiple output ports 110 for charging devices to be charged, wherein a first portion of the multiple output ports 110 is located on the top surface 100 of the housing, a second portion of the multiple output ports 110 is located on the bottom surface of the housing, and a third portion of the multiple output ports 110 is located on the side surface of the housing, and the output current and output voltage of each output port 110 are adjustable; a support frame 112 and a wireless charging coil 111 for charging devices to be wirelessly charged, wherein the wireless charging coil 111 is disposed on one side surface of the housing, the support frame 112 is slidably connected to the housing and faces the wireless charging coil 111, when the support frame 112 is closed, the support frame 112 is in contact with the wireless charging coil 111, and when the support frame 112 is unfolded, the area between the support frame 112 and the side surface of the housing where the wireless charging coil 111 is disposed is used to fix the devices to be wirelessly charged.

[0030] The closed support frame 112 not only protects the wireless charging coil 111, but also reduces the size of the multi-functional charger, making it more convenient to carry.

[0031] In some examples, output jack 110 can be a USB (Universal Serial Bus) interface.

[0032] In some examples, refer to Figure 1 and Figure 2 The support frame 112 is slidably connected to the housing via a strip slider 123. The housing has an extension hole. One end of the strip slider 123 is connected to the support frame 112, and the other end of the strip slider 123 extends into the extension hole. The housing has a fixing plate 121 and a fixing screw 120 that passes through the fixing plate 121. By tightening the fixing screw 120 into the fixing plate 121, the strip slider 123 can be limited in the extension hole to ensure that the support frame 112 is stably closed. When the support frame 112 needs to be unfolded, the fixing screw 120 can be screwed out in the direction away from the fixing plate 121 to unfold the support frame 112.

[0033] In some examples, refer to Figure 4 and Figure 5 The housing has a fixing plate 121 and fixing screws 120 that pass through the fixing plate 121. The support frame 112 is slidably connected to the housing via a strip slider 123. The housing has an extension hole. The fixing screws 120 are used to fix the fixing plate 121 to the housing to form the extension hole. One end of the strip slider 123 is connected to the support frame 112, and the other end of the strip slider 123 extends into the extension hole. The ends of the strip slider 123 extending into the extension hole have protrusions on both sides facing the top and bottom surfaces of the housing. The protrusions are used to prevent the strip slider 123 from falling out of the extension hole. The housing is also provided with a connecting piece 124 and an adjusting rod 125. The connecting piece 124 is fixed to the bottom surface of the housing, and the adjusting rod 125 passes through the housing, with one end of the adjusting rod 125 passing through... The spring is connected to the connecting piece 124. The other end of the adjusting rod 125 protrudes from the top surface of the housing. The adjusting rod 125 has a limiting rod 128. The strip slider 123 has multiple limiting holes 127 arranged at intervals. By pressing the adjusting rod 125 exposed on the top surface of the housing and then pulling the strip slider 123 relative to the housing, the limiting rod 128 can be selectively inserted into the corresponding limiting hole 127 to control the distance between the support frame 112 and the side of the housing where the wireless charging coil 111 is set. This allows the support frame 112 to be stably fixed at different distances relative to the side of the housing where the wireless charging coil 111 is set, thereby enabling the clamping of wireless charging devices of different sizes and limiting the position of the strip slider 123.

[0034] Furthermore, the multi-functional charger also includes multiple displays 114 and multiple button modules 117, with each display 114 and button module 117 corresponding to the other. The wireless charging coil 111 and each output port 110 also have a corresponding display 114 and button module 117. The button module 117 is used to adjust the output voltage and output current of the corresponding wireless charging coil 111 or output port 110, and the display 114 is used to display the output voltage and output current of the corresponding wireless charging coil 111 or output port 110. Thus, the button module 117 can be used to adjust the output current and output voltage of the corresponding output port 110 or wireless charging coil 111 according to actual usage needs, and the display 114 provides a clear view of the output current and output voltage status of the corresponding output port 110 or wireless charging coil 111.

[0035] Furthermore, each display 114 includes a first display unit and a second display unit, and each button module 117 includes a first button 115 and a second button 116. The first display unit is used to display the output voltage of the corresponding wireless charging coil 111 or output socket 110, and the second display unit is used to display the output current of the corresponding wireless charging coil 111 or output socket 110. The first button 115 is used to adjust the output voltage of the corresponding wireless charging coil 111 or output socket 110, and the second button 116 is used to adjust the output current of the corresponding wireless charging coil 111 or output socket 110.

[0036] Furthermore, the first part of the output socket 110 includes at least two output sockets 110, and the second part of the output socket 110 includes at least two output sockets 110.

[0037] Furthermore, the third output port 110 includes an output port 110, and multiple sides are connected in sequence as a first side 101, a second side 102, a third side 103 and a fourth side 104. The third output port 110 is located on the first side 101, and the wireless charging coil 111 is located on the second side 102.

[0038] In some examples, the display 114 and button module 117 corresponding to the output port 110 are disposed on the housing adjacent to the corresponding output port 110.

[0039] In some examples, the multi-functional charger includes nine output ports 110, ten displays 114, and ten button modules 117. The first part of the output ports 110 includes four output ports 110, the second part of the output ports 110 includes four output ports 110, and the third part of the output ports 110 includes one output port 110. The displays 114 and button modules 117 corresponding to the wireless charging coil 111 are all located on the first side 101.

[0040] Furthermore, the multi-functional charger also includes a power plug 118, located on the third side 103. The power plug 118 is rotatable relative to the housing. When closed relative to the housing, the power plug 118 is embedded in the housing; when unfolded relative to the housing, the power plug 118 extends outward from the housing. When unfolded, the power plug 118 connects to an external power source for charging. This design helps to reduce the size of the multi-functional charger, making it more portable.

[0041] Furthermore, the casing has multiple heat dissipation holes. These holes are designed for effective and rapid heat dissipation from the multi-functional charger.

[0042] Furthermore, the housing has an internal mounting cavity, and the multi-functional charger also includes a control board with a protection circuit.

When the charger malfunctions, the protection circuit activates the alarm, thus ensuring the charger has a safety protection mechanism and helping to prevent accidents.

[0043] In some embodiments, the control board is further provided with a main circuit and a transformer circuit.

[0044] In some embodiments, the alarm includes a buzzer and an indicator light 113. The buzzer can be used to alert to abnormal charging and prevent accidents. The indicator light 113 can be green under normal use and can be red or off when there is an abnormal charging.

[0045] Furthermore, the multi-functional charger also includes a battery and a solar energy conversion device. The battery is housed within the mounting cavity, while the solar energy conversion device is located on the surface of the casing. The solar energy conversion device converts solar energy into electrical energy and stores it in the battery. The battery can charge electronic devices without an external power source, and it can also be charged using an external power source, allowing the multi-functional charger to function as a portable power source for charging electronic devices outdoors or in the absence of an external power source.

[0046] Furthermore, when the support frame 112 is closed, the overall structure formed by the support frame 112 and the shell is rectangular. This improves the aesthetics.

[0047] It should be noted that the multi-functional charger provided by this utility model can be used to charge electronic devices such as tablets, laptops, smart bracelets, power banks, mobile phones or smart glasses, and has stronger applicability and practicality.
