Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the representation of this disclosure, "a set" means two or more, unless otherwise explicitly specified.

[0055] For the purpose of clarity, devices unrelated to the description are omitted, and the same or similar components throughout the specification are given the same reference numerals.

[0056] Throughout this specification, when it is said that a device is "connected" to another device, this includes not only "direct connection" but also "indirect connection" by placing other components in between. Furthermore, when it is said that a device "comprises" a certain constituent element, unless otherwise stated otherwise, this does not exclude other constituent elements, but rather implies that other constituent elements may be included.

[0057] While the terms first, second, etc., are used in some examples herein to refer to various elements, these elements should not be limited by these terms. These terms are used only to distinguish one element from another. For example, first interface and second interface, etc., are used. Furthermore, as used herein, the singular forms “a,” “an,” and “the” are intended to also include the plural forms unless the context indicates otherwise. It should be further understood that the terms “comprising,” “including,” indicate the presence of the stated feature, step, operation, element, module, item, kind, and / or group, but do not exclude the presence, occurrence, or addition of one or more other features, steps, operations, elements, modules, items, kinds, and / or groups.

Terms defined in commonly used dictionaries shall be further interpreted as having a meaning consistent with the relevant technical literature and the message of the present disclosure, and shall not be over-interpreted as having an ideal or overly formulaic meaning unless otherwise defined.

[0060] With the diversified applications of charging devices (such as portable medical instruments, power banks and their charging equipment), their usage methods are also varied, such as placing them on the ground or table, or hanging them on the wall. When switching between usage methods, the charging device is usually moved by lifting or picking it up. However, in related technologies, when moving the charging device, the user can only lift it by applying force to the left and right sides of the device. This method, because the force is not applied upwards, makes operating the mobile device laborious, and the user's hands cannot effectively interact with the charging device.

[0061] Based on the above issues, the grip opening facilitates the user's hand to reach inside and grasp the support structure. The combination of the user's hand and the support structure not only limits and prevents slippage between the user's hand and the device body, but also increases the binding force between the user's hand and the device body. It also makes it easier for the user to apply force from below to lift the device body, making it easier for the user to lift the charging device located on the supporting object.

[0062] Figure 1 The diagram shown is a schematic representation of the overall structure of the portable charging device in this disclosure. Figure 1 In the example, the movable charging device includes a device body 10 and a support structure 20.

[0063] For example, the support structure 20 extends outward from one end face of the device body 10 and includes at least one grip opening 21 that is recessed into the device body 10 and allows a user's hand to enter. The support structure 20 is disposed on one end face of the device body 10 and forms the grip opening 21 that is recessed into the device body 10.

[0064] The advantages of the above-mentioned design are that the grip opening 21 allows the user's hand to easily reach inside and grip the support structure 20. The combination of the user's hand and the support structure 20 not only provides a limiting and anti-slip function between the user's hand and the device body 10, but also increases the binding force between the user's hand and the device body 10. It also makes it easier for the user to apply force from below to lift the device body 10, making it easier for the user to lift the charging device located on the supporting object.

[0065] Exemplarily, the supporting object can be a table, stool, or the ground. In this application, the movable charging device is implemented as a charger that can be lifted by force applied to the grip. This charger, due to the large number of built-in components, is both large in size and heavy. This charging device is implemented to charge vehicles, batteries, or directly connect to electrical sources. It is typically placed directly on the ground or tabletop. When the placement changes due to changes in usage, the charging device is inconvenient for users to lift due to its weight and size. Furthermore, because existing charging devices lack features to facilitate lifting and prevent slippage, the charging device may slip and fall to the ground during transport. Therefore, the above-mentioned design is needed to solve these problems. In other embodiments, it can also be implemented as a larger battery cell or other charging device.

[0066] For example, the support structure 20 can support the device body 10 at a certain height, creating a certain gap between the device body 10 and the desktop or ground. This not only facilitates the user's hand to pass through and engage with the grip opening 21 on the support structure 20, thereby moving the charging device, but also improves the heat dissipation of the charging device, thus enhancing its performance.

[0067] For example, the support structure 20 includes at least one support member 22. The support member 22 is disposed at the bottom of the device body 10 and forms the grip opening 201.

[0068] In the first embodiment, the support structure 20 is implemented as including a support member 22 (not shown) disposed on the end face of the device body 10. For example, the support member 22 is implemented as one of annular, U-shaped, or C-shaped. In the first embodiment, the grip openings 21 are implemented as two and arranged opposite each other, which can further improve the effort-saving effect and comfort of the user in lifting the charging device. In other embodiments, one or more grip openings 21 may be implemented, and it is not limited thereto.

[0069] Figure 2 The diagram shown is a schematic representation of the overall structure of the movable charging device in this disclosure from another perspective. Figure 3 The diagram shown is a schematic representation of the overall structure of the movable charging device in this disclosure from another perspective. Figure 4 The diagram shown is a structural schematic of the support component in this disclosure. Figure 2 , Figure 3 and Figure 4 The example illustrates a structural schematic diagram of a second embodiment of this disclosure. Figure 2 and Figure 3 In the example, the support members 22 are implemented as a pair and arranged opposite each other.

[0070] Preferably, the two support members 22 are arranged at intervals along the length direction of the device body 10. More preferably, the two support members 22 are respectively located near the two edges of the device body 10 along its length direction on the end face of the device body 10, to further facilitate the user in lifting the charging device.

[0071] In the example, each of the support members 22 has a gripping opening 21 formed thereon. Exemplarily, each support member 22 includes two support portions 221 and the gripping opening 21 located between the two support portions 221. It is understood that the support member 22 is a support plate, and the gripping opening 21 is formed by an upwardly recessed portion in the middle region of the bottom wall of the support member 22. A support portion 221 is formed at each of the two ends along the length of the support member 22. In other embodiments, the gripping opening 21 is implemented as being formed by an inwardly recessed portion in the outer wall of the support member 22.

[0072] In other embodiments, the two support members 22 are configured such that one support member 22 has one grip opening 21 and the other support member 22 does not have a grip opening 21; or, one support member 22 has two grip openings 21 and the other support member 22 does not have a grip opening 21; or, each support member 22 has one or two grip openings 21. This facilitates two users moving a charging device simultaneously, further saving users' effort and improving comfort.

[0073] Preferably, the grip opening 21 is rectangular in shape and its size is adapted to the user's palm, improving user comfort. Further exemplarily, the grip opening 21 is configured to allow the user's palm to pass through. In other embodiments, the grip opening 21 may also be arc-shaped, and is not limited thereto. However, regardless of the shape, its size should be adapted to the user's palm.

[0074] For example, the grip opening 21 is implemented as a single one, and a ventilation path (not shown) is formed between the single grip opening 21 and the device body 10.

[0075] exist Figure 2 and Figure 3 In this example, two grip openings 21 are implemented, arranged opposite each other to form a ventilation path (not shown in the figure). Those skilled in the art will understand that charging devices typically have heat dissipation vents on their end faces to maintain performance. The oppositely arranged grip openings 21 can effectively manage the hot airflow from the heat dissipation vents, thereby improving the heat dissipation performance of the charging device.

[0076] For example, the support member 22 is made of rubber, and the support portion 221 is provided with an anti-slip portion (not shown in the figure), such as a silicone layer or a frosted layer. It is understood that when the device body 10 is placed on the surface of the supporting object, the anti-slip portion can increase the friction between the device body 10 and the surface of the supporting object, thereby playing an anti-slip role and preventing the charging device from shifting its position on the surface of the supporting object.

[0077] As a further example, the support member 22 is elastic and has rounded edges. The advantage of this design is that, since the hand is in direct contact with the rubber support member 22 with rounded edges, it can prevent the user's hand from being squeezed by the hard support member 22 and causing excessive local pressure and discomfort, while also preventing the user's hand from being injured by the support member 22.

[0078] For example, the grip opening 21 is also provided with an anti-slip part (not shown in the figure), such as a silicone layer or a frosted layer. The anti-slip unit provided on the grip opening 21 can increase the friction between the user's palm and the grip opening 21, and prevent the charging device from falling to the ground and being damaged during movement due to the user's palm slipping off the grip opening 21.

[0079] Figure 5 The diagram shown is a schematic diagram of the suspension structure in this disclosure. Figure 6 The diagram shown is a cross-sectional view of the suspension structure 30 in this disclosure. Figure 3 , Figure 5 and Figure 6 In the example, the movable charging device further includes a suspension structure 30. The suspension structure 30 includes a first suspension member 31 and a second suspension member 32 that are detachably connected, respectively disposed on the surface of the suspended object and the device body 10.

[0080] For example, the suspension structure 30 is disposed on the end face, which serves as the bottom surface of the charging device when it is laid flat. It is understood that when the charging device is laid flat, the end face faces the surface of the support; while when the charging device is suspended, the end face faces the surface of the suspended object.

[0081] For example, the first suspension member 31 and the second suspension member 32 are engaged in a vertical direction. The first suspension member 31 is provided with a support portion 311; the second suspension member 32 is formed with an engagement portion 321 for engaging with the support portion 311.

[0082] Further exemplarily, the first suspension member 31 is disposed on the surface of the suspended object and has two spaced-apart support portions 311, and the second suspension member 32 is implemented as a pair and spaced-apart on the end face of the device body 10. The first suspension member 31 is implemented as a support plate, and the support portion 311 is a protruding portion of the support plate with a U-shaped cross-section and an opening facing the surface of the suspended object. The engaging portion 321 is implemented as a U-shaped buckle with an opening facing downward, and the U-shaped buckle has an engaging cavity for accommodating the support portion 311.

[0083] For example, each of the second suspension members 32 has a limiting portion 322 for preventing the support portion 311 from disengaging from the engaging portion 321. In other embodiments, one of the second suspension members 32 has the limiting portion 322.

[0084] As further exemplarily, the sidewall of the second suspension member 32 facing the surface of the suspended object forms the limiting portion 322 at the opening of the engaging portion 321. The limiting portion 322 forms, in sequence, an abutting portion 3221 that abuts against the device body 10, and a guide portion 3222 that is inclined and guides the support portion 311 into the engaging portion 321. Those skilled in the art will understand that both the first suspension member 31 and the second suspension member 32 are made of sheet metal, such as stainless steel or copper. Therefore, the second suspension member 32, having a certain length and thickness, possesses elasticity. The abutting portion 3221, due to its own elasticity, remains in the position abutting against the device body 10, thereby preventing the support portion 311 from disengaging from the engaging portion 321.

[0085] As a further example, the length of the support portion 311 is greater than the length of the engaging portion 321, so that the support portion 311 can be smoothly engaged and connected to the engaging portion 321.

[0086] Those skilled in the art will understand that the advantages of the above-described configuration are that it allows users to easily place the device body 10 on a suspended surface, such as a wall. Furthermore, the width of the support portion 311 is greater than the width of the engaging portion 321, and the guide portion 3222 allows for quick placement of the device body 10 on the suspended surface.

[0087] In other embodiments, the first suspension member 31 is disposed on the end face of the device body 10, and the second suspension member 32 is implemented as two members spaced apart on the surface of the suspended object. In this embodiment, the first suspension member 31 is implemented as a support plate, and the support portion 311 is a protruding portion of the support plate with a U-shaped cross-section and an opening facing the device body 10. The engaging portion 321 is implemented as an upward-facing U-shaped buckle, the U-shaped buckle including an engaging cavity for accommodating the support portion 311.

[0088] In other embodiments, the first suspension member and the second suspension member are magnetically connected.

[0089] Figure 7 The diagram shown is a structural schematic of another embodiment of the suspension structure 30 in this disclosure. Figure 7 In the example, the first suspension member 31 is provided with a support portion 311, and the second suspension member 32 is provided as a pair and spaced apart on the end face of the device body 10. The length of the support portion 311 is greater than the total length of the two engaging portions 321.

[0090] In the above embodiments, the first suspension member 31 and the second suspension member 32 are respectively fixedly connected to the surface of the suspended object and the end face of the device body 10 by screws.

[0091] Figure 8 The diagram shown is a circuit connection schematic of a movable charging device according to an embodiment of this disclosure. Figure 8 In the example, the device body includes a main power control board 40. The main power control board 40 includes a printed circuit board (e.g., a PCBA circuit board) on which various components are arranged to form different functions. Exemplarily, the main power control board 40 can be fixed to the housing by screws. Exemplarily, the main power control board 40 can be fixed to the housing by a thermally conductive adhesive potting process.

[0092] For example, the power main control board 40 includes an AC-DC conversion module 41, a voltage conversion module 42, and a power management module 43.

[0093] The AC-DC conversion module 41 converts the input alternating current into direct current. For example, the AC-DC conversion module 41 may be a rectifier.

[0094] The voltage conversion module 42 can be electrically connected to the AC-DC conversion module 41 for voltage conversion. There may be more than one voltage conversion module 42. For example, one voltage conversion module 42 is connected to the output terminal of the AC-DC conversion module 41 to convert the signal at the output terminal of the AC-DC conversion module 41 into a first operating voltage. For example, two voltage conversion modules 42 are connected to the output terminal of the AC-DC conversion module 41, wherein the first voltage conversion module 42 is used to convert the signal at the output terminal of the AC-DC conversion module 41 into a first operating voltage, and the second voltage conversion module 42 is used to convert the signal at the output terminal of the AC-DC conversion module 41 into a second operating voltage.

[0095] For example, a first voltage conversion module is connected to the output terminal of the AC-DC conversion module 41, and a second voltage conversion module is connected to the output terminal of the first voltage conversion module. The first voltage conversion module converts the signal at the output terminal of the AC-DC conversion module 41 into a first operating voltage, and the second voltage conversion module converts the signal at the output terminal of the first voltage conversion module into a second operating voltage. For example, the voltage conversion module 42 may be a transformer.

[0096] In some embodiments, the power supply main control board 40 further includes a filter circuit and a voltage regulator circuit. For example, the filter circuit and the voltage regulator circuit are sequentially connected to the voltage conversion module 42.

[0097] In some embodiments, the power main control board 40 further includes a power supply path selection circuit connected to the power management module 43. The power supply path selection circuit is used to select either a first power supply path corresponding to the external electrical device or a second power supply path corresponding to the energy conversion device, depending on whether the power output interface is electrically connected to an external electrical device or an energy conversion device.

[0098] The power input interface or power input connector is located on the surface of the device body 10 and connected to the main power control board 40. It connects to AC power to input electrical energy. For example, a cable with a plug interface and a power input connector is provided. The plug interface of the cable connects to the power input interface of the charging device, and the power input connector connects to AC power. Exemplarily, the power input connector is a two-prong plug. Exemplarily, the power input connector is a three-prong plug with a grounding terminal. By providing this power input interface, more options are available.

[0099] The power output interface is located on the surface of the device body 10 and is electrically connected to the power main control board 40. Using the power output interface, electrical energy can be output through a cable with a plug that matches the power output interface.

[0100] In other embodiments, the portable charging device includes a device body 10 and a support structure 20. The device body 10 houses a power main control board 40; the power main control board 40 includes a power management module 43 and a power output interface. The power output interface is located on the device body 10 and electrically connected to the power main control board 40 for outputting electrical energy. The support structure 20 extends outward from one end of the device body 10 and includes at least one grip opening 21 recessed into the device body 10 for a user's hand to enter. In this embodiment, the portable charging device can only be used to provide power to electrically connected external devices. For example, a battery cell is housed within the housing. Preferably, the battery cell is detachably housed within the housing to facilitate replacement of the battery cell with different capacities.

[0101] Figure 9 The diagram shows the connection between the power adapter and the gardening vehicle. Figure 9In this example, another embodiment of the present disclosure provides a power adapter, wherein the charging device is implemented as the power adapter. Exemplarily, the power adapter is used to replenish the power of a gardening vehicle 50. The gardening vehicle 50 includes an energy storage component 51, such as a lithium battery or lead-acid battery. A connector 11 for connecting to an external device is formed on the surface of the device body 10. The power adapter electrically connects the energy storage component 51 to the connector 11 via a charging cable harness 52 to replenish the power of the gardening vehicle 50.

[0102] Figure 10 The diagram shows the connection between the power adapter and the charging dock. Figure 10 In another embodiment of this disclosure, a power adapter is provided. The charging device is implemented as the power adapter. Exemplarily, the power adapter is used to provide power to a charging dock 60 to which a battery pack is plugged. The surface of the device body 10 has a connection port (not shown) for connecting to an external device, and the charging dock 60 is electrically connected to the power adapter via a charging harness 61. Exemplarily, the charging dock 60 is configured to charge two battery packs 62 simultaneously. That is, the charging dock 60 includes at least two charging ports (not shown) for plugging into the battery packs 62.

[0103] Understandably, in Figure 9 and Figure 10 In the illustrated embodiment, the portable charging device implemented as the power adapter can be suspended on a wall or placed flat on the ground. Regardless of the method, the grip opening 21 on the support structure 20 facilitates the operator's hand to reach into and grip the support structure 20, which serves to limit the user's hand and prevent slippage between the user's hand and the device body 10. This allows the user to apply force from below to lift the device body 10, making the operation of lifting the portable charging device simple and effortless.

[0104] In summary, this disclosure provides a portable charging device and a power adapter. The portable charging device includes a device body and a support structure. The device body includes a housing and a main power control board disposed within the housing; the main power control board includes an AC-DC conversion module, a voltage conversion module, and a power management module; a power input interface or power input connector is disposed on the surface of the device body and electrically connected to the main power control board for connecting to an external power source to input electrical energy; and a power output interface is disposed on the surface of the device body and electrically connected to the main power control board for outputting electrical energy. The support structure extends outward from one end of the device body and includes at least one grip opening recessed into the device body for a user's hand to insert. The power adapter includes the portable charging device. The advantages of the above design are that the grip opening allows the user's hand to easily reach inside and grasp the support structure.
