DESCRIPTION OF EMBODIMENTS

The following describes implementations of the present disclosure by using specific embodiments. A person skilled in the art may easily learn of other advantages and effects of the present disclosure based on content disclosed in this specification. The present disclosure can be further implemented or applied in some other different specific implementations. Various details in this specification can also be modified or altered based on different viewpoints and applications without departing from the present disclosure.

Refer to FIG. 1 to FIG. 12. It should be noted that, the illustrations provided in some embodiments merely describe the basic concept of the present disclosure by using examples. Although the drawings show only components related to the present disclosure, and are not drawn based on a quantity of components, a shape of a component, and a size of a component during actual implementation, a shape, a quantity, and a scale of the components may be arbitrarily changed during actual implementation, and a component layout form may be more complex.

A high-density high-power charger with a weight of 380 g, a maximum power of 180 W, and a volume/weight of 1.15 g per cubic centimeter is used as an example. A length-to-width ratio of such charger is between 0.7 and 1.3, and a thickness-to-length ratio thereof is between 0.5 and 0.7. Such charger is very prone to fall off after being plugged into a socket.

In addition, based on data testing, when the charger is greater than or equal to 90 g, there is a high probability of falling off after the charger is plugged. If a charger body is heavier, the charger is more prone to fall off. In addition, when a socket plug interface is loose, the probability of falling off is higher. To resolve a problem that a heavy charger falls off during use when the heavy charger is plugged into a socket or a socket plug interface is loose, the present disclosure provides a charger with an anti-falling function. FIG. 1 to FIG. 12 are schematic diagrams of structures of a charger with an anti-falling function in four different implementations.

As shown in FIG. 1 to FIG. 12, the charger includes a charger body 10 and an auxiliary support assembly. The auxiliary support assembly is mounted on the charger body 10. The auxiliary support assembly is configured such that when the charger body 10 is plugged into a socket, the auxiliary support assembly is capable of generating a mutual acting force with the socket or an interface on which the socket is located, and the acting force generated by the socket or the interface on the auxiliary support assembly is capable of counteracting or weakening torque generated by the charger body 10 due to gravity of the charger body or an external force (for example, a pulling force generated externally when the charger is connected to a power tool or an electrical appliance). Therefore, a problem that the charger is prone to fall off due to gravity of the charger when the charger is plugged into the socket can be avoided. For example, the socket may be, for example, a wall socket, and an interface on which the wall socket is located may be, for example, a wall surface 20. The socket may be alternatively mounted on a panel, and the panel herein is the interface.

It should be noted that, in the present disclosure, the auxiliary support assembly includes a first component and/or a second component, and the first component and/or the second component are/is connected to at least one surface of the charger body 10, and generate/generates an acting force on the charger body 10 in at least one direction. The following is described in detail by using an example in which the first component is a suction cup component and the second component is an inclined support component.

The suction cup component includes a small suction cup component shown in FIG. 1 to FIG. 3 and an integral suction cup component shown in FIG. 4 and FIG. 5, and the inclined support component includes a first inclined support component 40 shown in FIG. 6 to FIG. 9 and a second inclined support component 50 shown in FIG. 10 to FIG. 12.

It should be noted that, for ease of description, that the charger body 10 is substantially in a cubic shape is used as an example for description. A surface, of the charger body 10, on which a charging pin 12 is disposed is defined as a front end face (also referred to as a plug surface), and a surface opposite to the front end face is defined as a rear end face. An output port such as a USB output port, a Type-C output port, an 8-shaped interface and a plum blossom interface may be disposed on the rear end face. Four surfaces other than the front end face and the rear end face are defined as annular sidewall surfaces. A surface located on an upper side of the charger body 10 when the charger body 10 is plugged into the socket is defined as a top surface, and a surface located on a lower side is defined as a bottom surface.

The following describes in detail charger structures with different auxiliary support assemblies in the present disclosure with reference to specific embodiments.

FIG. 1 to FIG. 3 show an implementation of an anti-falling charger according to the present disclosure. In this implementation, the charger includes a charger body 10 and a suction cup component. The suction cup component includes a first suction cup 30 and a first connection part 31, and a side that is of the first suction cup 30 and that is away from an adhesive surface is connected to the first connection part 31. The first suction cup 30 is fixedly or detachably mounted on a front end face of the charger body 10 by using the first connection part 31. The suction cup component is added to the front end face of the charger body. In this way, when the charger body 10 is plugged into a socket, an adhesive force generated between the first suction cup 30 of the suction cup component and the socket or a wall surface 20 on which the socket is located is used to cancel or weaken torque generated by the charger body 10 due to gravity of the charger body or an external force, thereby playing an anti-falling role.

As shown in FIG. 1 to FIG. 3, detachable mounting of the suction cup component to the front end face of the charger body 10 may be implemented in the following manner: a first T-shaped slot 11 is disposed inwardly on the front end face of the charger body 10, and the first T-shaped slot 11 extends from the inside of the front end face to an edge, and penetrates the annular sidewall surface of the charger body 10. The first connection part 31 is disposed as a T-shaped insertion part (first T-shaped insertion part), and the first T-shaped insertion part is detachably plugged into the first T-shaped slot 11 by means of an interference fit, to facilitate detachment when the charger is not in use.

For example, as shown in FIG. 1 to FIG. 3, an upper end and a lower end of the front end face of the charger body 10 are respectively provided with one first T-shaped slot 11, and there are two small suction cup components. The two suction cup components are detachably mounted on the upper end and the lower end of the front end face by using respective first T-shaped insertion parts. Therefore, when the charger body 10 is plugged into the socket, adhesive forces between the suction cup components at the upper end and the lower end of the front end face and the socket or the wall surface 20 on which the socket is located are used to cancel or weaken torque generated by the charger body 10 due to gravity of the charger body or an external force, thereby playing an anti-falling role. Certainly, the first T-shaped slot 11 may be replaced with another type of slot structure, and is not limited to a T-shaped slot structure. Correspondingly, the first T-shaped insertion part is also correspondingly adjusted.

It should be noted that the first T-shaped slot 11 may be disposed at any location on an outer periphery of the front end face of the charger body 10, and there may be one or more T-shaped slots 11. Therefore, the suction cup component may be disposed at any location that is on the front end face of the charger body 10 and that does not affect the charging pin. There may be one or more suction cup components 30. In addition, a shape of the first suction cup 30 of the suction cup component may be a spherical surface or an adhesive surface of any shape.

It should be noted that the suction cup component in the first implementation is connected to the charger body 10 through insertion. In addition, the suction cup component may also be mounted on the charger body 10 in a manner such as buckling, threaded connection, bonding, or welding. The threaded connection is used as an example. For example, an end that is of the first connection part 31 of the suction cup component and that is not connected to the first suction cup 30 may be manufactured into a threaded section, and a threaded hole is disposed at a corresponding location on the charger body 10, thereby implementing a threaded connection between the first connection part 31 and the charger body 10.

FIG. 4 and FIG. 5 show another implementation of an anti-falling charger according to the present disclosure. This implementation is a variation of the first implementation in FIG. 1 to FIG. 3. Different from the charger shown in FIG. 1 to FIG. 3, in this implementation, a size of the first suction cup 30 is larger, and a shape of the first connection part 31 is also different.

Specifically, as shown in FIG. 4 and FIG. 5, the suction cup component includes a first suction cup 30 and a first connection part 31. A side that is of the first suction cup 30 and that is away from an adhesive surface is connected to the first connection part 31. A central hole 32 that sequentially runs through the first suction cup 30 and the first connection part 31 is disposed on the first component, and the central hole 32 matches an annular sidewall surface of the charger body 10, so that the suction cup component is capable of being sleeved, in a sealing manner based on the central hole 32, on a part that is of the annular sidewall surface and that is close to a front end face. The first connection part 31 is formed into an external shape of the charger, so that the entire suction cup component can be sleeved on the charger body 10. When in use, the charger body 10 is directly plugged into the socket, and an adhesive force between the first suction cup 30 and the socket or the wall surface 20 is used to cancel or weaken torque generated by the charger body 10 due to gravity of the charger body or an external force, thereby playing an anti-falling role.

To resolve a problem that the first suction cup 3 in FIG. 1 to FIG. 5 cannot be adhered because the socket or an area that is around the socket and that is adjacent to the wall surface 20 is irregular, FIG. 6 to FIG. 9 show a third implementation of an anti-falling charger according to the present disclosure.

In this implementation, the charger includes a charger body 10 and a first inclined support component 40. The first inclined support component 40 includes a second connection part 42, a connection rod 41, and a second suction cup 44 (used as a positioning component). A first end of the second connection part 42 is hinged to a first end of the connection rod 41, and a second end of the second connection part 42 is mounted on a top surface of the charger body 10. A side that is of the second suction cup 44 and that is away from the socket is hinged to a second end of the connection rod 41. The connection rod 41 is a telescopic rod.

When the charger body 10 is plugged into the socket, a length of the telescopic rod may be adjusted, so that the second suction cup 44 can be adhered to a location that is on the wall surface 20 and that is suitable for adhesion. Therefore, the first inclined support component 40 provides an upward inclined pulling force, and a vertical component of the inclined pulling force is used to cancel or weaken torque generated by the charger body 10 due to gravity of the charger body or an external force. In addition, a horizontal component of the inclined pulling force may be used to provide the charger body 10 with a pressure towards the socket, to prevent the charger from falling off.

As shown in FIG. 6 to FIG. 9, to implement detachable mounting of the first inclined support component 40 to the charger body 10, a second T-shaped slot 13 is disposed inwardly on the top surface of the charger body 10, and the second T-shaped slot 13 extends from the inside of the top surface to an edge, and penetrates the rear end face of the charger body 10. The second connection part 42 includes a second T-shaped insertion part 422 and a first hinge body 421. A first end of the second T-shaped insertion part 422 is fixedly connected to the first hinge body 421, and a second end of the second T-shaped insertion part 422 is detachably plugged into the second T-shaped slot 13 by means of an interference fit. The first hinge body 421 is rotatably mounted in an end support cavity of the connection rod 41. Certainly, the ball hinge connection manner herein may be replaced with a shaft hinge connection manner. Certainly, the second T-shaped slot 13 may be replaced with another type of slot structure, and is not limited to a T-shaped slot structure. Correspondingly, the second T-shaped insertion part is also correspondingly adjusted. Certainly, the second connection part 42 may be connected to the charger body 10 in a manner such as buckling, threaded connection, bonding, or welding.

To limit a motion range of the connection rod 41 and facilitate storage, a first notched groove 43 is disposed on a side that is of the connection rod 41 and that is opposite to the second T-shaped insertion part 422, the first notched groove 43 interconnects with the end support cavity, and the second T-shaped insertion part 422 is fixedly connected to the first hinge body 421 after passing through the first notched groove 43, so that the connection rod 41 can be adjusted only in a specific angle range along the first notched groove.

It should be noted that, to implement a better anti-falling effect, an included angle between the telescopic rod and the wall surface 20 on which the socket is located is between 30° and 70°, for example, 30°, 40°, 50°, 60°, or 70°.

As shown in FIG. 6 to FIG. 9, the second suction cup 44 and the connection rod 41 may be connected in a ball hinge connection manner. Specifically, the second suction cup 44 has a second hinge body 441, and the second hinge body 441 is rotatably mounted in the end support cavity of the connection rod 41. To limit a motion range of the second suction cup 44 and facilitate storage, a second notched groove 45 is disposed on a sidewall at an end that is of the connection rod 41 and at which the second suction cup 44 is disposed, and the second notched groove 45 interconnects with the end support cavity. A tail of the second suction cup 44 is fixedly connected to the second hinge body 441 after passing through the second notched groove 45, so that rotation adjustment of the second suction cup 44 can be performed only in a specific angle range along the second notched groove 45.

It should be noted that, similar to FIG. 10 to FIG. 12, the first inclined support component 40 may be mounted on the bottom surface of the charger body 10. When the charger body 10 is plugged into the socket, a length of the telescopic rod may be adjusted, so that the second suction cup 44 can be adhered to a location that is on the wall surface 20 and that is suitable for adhesion. Therefore, a vertical component of an inclined support force that is provided by the first inclined support component 40 and that is applied to the bottom surface of the charger body near the rear end face is used to cancel or weaken torque generated by the charger body 10 due to gravity of the charger body or an external force, to prevent the charger from falling off.

To resolve a problem that the charger cannot be prevented from falling off through adhesion by using the first suction cup 30 in FIG. 1 to FIG. 5 when the wall surface 20 around the socket is irregular, FIG. 10 to FIG. 12 show a fourth implementation of an anti-falling charger according to the present disclosure.

In this implementation, the charger includes a charger body 10 and a second inclined support component 50. Compared with the first inclined support component 40, the second inclined support component 50 includes a second connection part 42, a connection rod 41, and a positioning component. Different from the first inclined support component 40, a positioning plate 46 instead of the second suction cup 44 is used as the positioning component, and the second inclined support component 50 is mounted on the bottom surface of the charger body 10. Of course, in other embodiments, the positioning plate 46 may also be a suction cup, similar in structure to second suction cup 44.

Specifically, the second inclined support component 50 includes a second connection part 42, a connection rod 41, and a position plate 46. A first end of the second connection part 42 is hinged to a first end of the connection rod 41, and a second end of the second connection part 42 is mounted on the bottom surface of the charger body 10. A side that is of the positioning plate 46 and that is away from the socket is hinged to a second end of the connection rod 41. The connection rod 41 is a telescopic rod. When the charger body 10 is plugged into the socket, a length of the telescopic rod may be adjusted. The charger body 10 applies a force to the positioning plate 46 due to gravity of the charger body, the force is applied along the second inclined support component 50, and a friction force between the positioning plate 46 and the wall surface is used to support the charger at a proper location on the wall surface 20. Therefore, a vertical component of an inclined support force that is provided by the second inclined support component 50 and that is applied to the bottom surface of the charger body near the rear end face is used to cancel or weaken torque generated by the charger body 10 by gravity of the charger body or an external force, to prevent the charger from falling off.

As shown in FIG. 10 to FIG. 12, to implement detachable mounting of the second inclined support component 50 to the charger body 10, a second T-shaped slot 13 is disposed inwardly on a bottom surface of the charger body 10, and the second T-shaped slot 13 extends from the inside of the bottom surface to an edge, and penetrates the rear end face of the charger body 10. Similarly to the mounting manner of the first inclined support component 40, the second inclined support component 50 is detachably mounted on the second T-shaped slot 13 on the bottom surface of the charger body 10 by using the second T-shaped insertion part 422 of the second connection part 42.

It should be noted that, to implement a better anti-falling effect, an included angle between the telescopic rod and the wall surface 20 on which the socket is located is between 30° and 70°, for example, 30°, 40°, 50°, 60°, or 70°.

As shown in FIG. 10 to FIG. 12, the positioning plate 46 and the connection rod 41 may be connected in a ball hinge connection manner. Specifically, the positioning plate 46 has a third ball hinge body 461, and the third ball hinge body 461 is rotatably mounted in the end support cavity of the connection rod 41. To limit a motion range of the positioning plate 46 and facilitate storage, a second notched groove 45 is disposed on a sidewall at an end that is of the connection rod 41 and at which the positioning plate 46 is disposed, and the second notched groove 45 interconnects with the end support cavity. A tail of the positioning plate 46 is fixedly connected to the third ball hinge body 461 after passing through the second notched groove 45, so that rotation adjustment of the positioning plate 46 can be performed only in a specific angle range along the second notched groove 45.

It should be noted that in the present disclosure, in the ball hinge connection manner, the ball hinge body and the corresponding end support cavity may be mounted by means of an interference fit. Therefore, relative locations of two parts connected through ball hinge connection are kept unchanged by using a friction force between the ball hinge body and the corresponding end support cavity without an external force.

It should be noted that in the present disclosure, the suction cup component or the inclined support component may be selected as the auxiliary support assembly based on regularity of the wall surface around the socket and a factor of the charger body 10, or both the suction cup component and the inclined support component may be used as the auxiliary support assembly, to generate a larger force on the auxiliary support assembly with the socket or the wall surface 20 to cancel or weaken torque generated by the charger body due to gravity of the charger body or an external force, thereby increasing an anti-falling probability.

In conclusion, according to the charger in the present disclosure, the auxiliary support assembly is amounted on the charger body 10, and the auxiliary support assembly is configured such that when the charger body 10 is plugged into the socket, the auxiliary support assembly is capable of generating a mutual acting force with the socket or the wall surface 20 on which the socket is located, and an acting force generated by the wall surface 20 on the auxiliary support assembly is capable of counteracting or weakening torque generated by the charger body 10 due to gravity of the charger body or an external force, so that the mutual acting force exerted between the auxiliary support assembly and the socket or the wall surface 20 on which the socket is located is used to fasten the charger to the socket or the wall surface 20 on which the socket is located. Therefore, the charger is not prone to fall off.

The present disclosure further discloses a charging system, including a power tool and a charger adapted to the power tool. The charger is connected to the power tool, and is configured to provide power for the power tool.

The charger includes a charger body 10 and an auxiliary support assembly. The auxiliary support assembly is mounted on the charger body 10. The auxiliary support assembly is configured such that when the charger body 10 is plugged into a socket, the auxiliary support assembly is capable of generating a mutual acting force with the socket or a wall surface 20 (interface) on which the socket is located, and the acting force generated by the socket or the wall surface 20 on the auxiliary support assembly is capable of counteracting or weakening torque generated by the charger body 10 due to gravity of the charger body. Therefore, a problem that the charger is prone to fall off due to gravity of the charger when the charger is plugged into the socket can be avoided.
