Description

Technical Field

[0001] The present application relates to the field of charging technology, and in particular to a charging device. Background Art

[0002] Various mobile electronic devices such as mobile phones and tablets have been widely used in daily life. The functions of mobile electronic devices are becoming increasingly powerful, which has led to an increase in the frequency of users' use of mobile electronic devices. The screen sizes of mobile electronic devices are also increasing, which has greatly accelerated the power consumption of mobile electronic devices and increased the demand for charging.

[0003] In the related art, a charging device is used to wirelessly charge mobile electronic devices. The charging device has a wireless charging surface, and the mobile electronic device can be charged by placing it on the wireless charging surface. However, the wireless charging surface is usually arranged horizontally, which makes it inconvenient for users to use the mobile electronic device while charging. Utility Model Content

[0004] To solve the above technical problems, the present application provides a charging device, in which the charging component can be flipped and extended relative to the base, so that users can use mobile electronic devices while charging them, and it can also be suitable for electronic devices of different sizes.

[0005] The present application provides a charging device, comprising: a base, a telescopic component, the telescopic component comprising a fixing member, the fixing member being rotatably connected to the base; and a charging component, the charging component being slidably connected to the fixing member.

[0006] In the technical solution of the embodiments of the present application, since the fixed member of the telescopic assembly is rotatably connected to the base, the angle of the telescopic assembly relative to the base can be adjusted, thereby adjusting the angle of the charging assembly, thereby aligning the mobile electronic device to an angle that is convenient for the user to view and operate, allowing the mobile electronic device to be used while charging. Since the charging assembly is slidably connected to the fixed member, the charging assembly can be moved closer to or further away from the base, making the charging device suitable for supporting and charging mobile electronic devices of different sizes.

[0007] In some embodiments, the telescopic component also includes a movable part connected to the charging component, and the movable part is telescopically connected relative to the fixed part. The movable part has a first surface opposite to the fixed part, and the fixed part has a second surface opposite to the movable part. The first surface is provided with a positioning bead, and the second surface is provided with a limiting hole that can engage with the positioning bead.

[0008] Because the first surface is provided with positioning beads, they help reduce friction between the first and second surfaces during movement of the movable member relative to the fixed member, ensuring smooth movement. This helps reduce wear during telescopic movement and increases the service life of the telescopic assembly. Because the second surface is provided with a retaining hole that engages with the positioning beads, the positioning beads engage when they move into the retaining hole, maintaining the movable member in a specific position and thus enabling the telescopic assembly to maintain a set length and provide stable support.

[0009] In some embodiments, the second surface is provided with a plurality of limiting hole groups, and the plurality of limiting hole groups are arranged along the telescopic direction of the telescopic component. The positioning beads are provided corresponding to a group of the limiting hole groups, wherein each of the limiting hole groups includes at least one limiting hole.

[0010] As a result, the telescopic assembly can be stably maintained at multiple lengths, so that the charging assembly can be suitable for charging and supporting mobile electronic devices of different sizes.

[0011] In some embodiments, the charging component includes a first wireless charging coil and a first shell, the first shell has a accommodating space, the first wireless charging coil and the moving part are both arranged in the accommodating space, the first shell is provided with a groove that connects the accommodating space with the outside world, and a portion of the fixing part is accommodated in the groove and is slidably connected to the groove.

[0012] In this way, the charging component is moved relative to the fixed part under the drive of the movable part.

[0013] In some embodiments, the inner wall surface of the groove is configured with a sliding groove, and the fixing member is configured with a protrusion, and the protrusion is slidably connected to the sliding groove.

[0014] As a result, the fixing member can slide in the slide groove, and the charging assembly can move freely along the extension and contraction direction of the slide groove.

[0015] In some embodiments, the telescopic assembly is rotatably connected to the base via a damping shaft structure.

[0016] Therefore, when adjusting the rotation angle of the charging assembly, you only need to flip the charging assembly to the required angle for use, which is convenient and quick to use.

[0017] In some embodiments, the damping shaft structure includes a support member, a damping column and a rotating shaft connected to the fixing member, the two support members are arranged on the base with a gap between them, the two damping columns are respectively arranged on the side of the support members away from each other, the two ends of the rotating shaft respectively pass through the support member and are rotatably connected to the support member, and the two ends of the rotating shaft respectively have through holes that can be interference fit with the damping column.

[0018] As a result, when the user rotates the shaft with their own strength, the holes on it and the damping column interfere with each other and generate greater friction. After the user stops applying force, the shaft is difficult to rotate under the small pressure of the mobile electronic device, and thus maintains the angle after rotation. It is convenient and quick to use.

[0019] In some embodiments, the damping shaft structure further includes a support cylinder surrounding the rotating shaft, the rotating shaft is connected to the fixing member through the support cylinder, and the support cylinder passes through the support member and is interference fit with the support member.

[0020] Therefore, the interference fit between the support tube and the support member further increases the rotational friction, so that the charging assembly can be more stably maintained at the angle required by the user.

[0021] In some embodiments, the base includes a second shell having a first shell wall for placing the charging component, and the first shell wall has a storage groove, and at least a portion of the charging component can be accommodated in the storage groove.

[0022] As a result, the charging assembly can be accommodated and protected by the storage slot, which helps save the space occupied by the charging device and also helps reduce the wear of the charging assembly.

[0023] In some embodiments, the base further includes a second wireless charging coil, which is disposed on the first shell wall. In the same projection plane parallel to the first shell wall, the projection of the second wireless charging coil and the projection of the storage slot do not overlap.

[0024] Thus, the user can freely use either the charging assembly or the position of the first housing wall adjacent to the charging assembly for charging, which is flexible to use. The charging device can also charge two mobile electronic devices at the same time, which is convenient and fast to use.

[0025] The above description is only an overview of the technical solution of the present application. In order to more clearly understand the technical means of the present application, it can be implemented in accordance with the contents of the specification. In order to make the above and other purposes, features and advantages of the present application more obvious and easy to understand, the specific implementation methods of the present application are listed below.

[0043] Below, this application is described in detail.

[0044] Various mobile electronic devices such as mobile phones and tablets have been widely used in daily life. The functions of mobile electronic devices are becoming increasingly powerful, which has led to an increase in the frequency of users' use of mobile electronic devices. The screen sizes of mobile electronic devices are also increasing, which has greatly accelerated the power consumption of mobile electronic devices and increased the demand for charging.

[0045] In the related art, a charging device is used to wirelessly charge mobile electronic devices. The charging device has a wireless charging surface, and the mobile electronic device can be charged by placing it on the wireless charging surface. However, the wireless charging surface is usually arranged horizontally, which makes it inconvenient for users to use the mobile electronic device while charging.

[0046] The inventors of this application have discovered that by changing the angle of the wireless charging surface, the surface can be aligned with and support the mobile electronic device, making it easier for users to charge and use the device simultaneously. Furthermore, by changing the length of the wireless charging surface, the surface can be adapted to mobile electronic devices of different sizes.

[0047] Based on such a design concept, the present application provides a charging device, which includes: a base, a telescopic component, the telescopic component includes a fixing part, the fixing part is rotatably connected to the base; and a charging component, the charging component is slidably connected to the fixing part.

[0048] Because the telescopic assembly's fixed member is rotatably connected to the base, the angle of the telescopic assembly relative to the base can be adjusted, thereby adjusting the angle of the charging assembly. This allows the mobile electronic device to be oriented for easy viewing and operation, allowing the user to use the mobile electronic device while charging. Because the charging assembly is slidably connected to the fixed member, the charging assembly can be moved closer to or further away from the base, making the charging device suitable for supporting and charging mobile electronic devices of different sizes.

[0049] The following is a description with reference to the accompanying drawings.

[0050] Figure 1 A three-dimensional schematic diagram of a charging device provided in one embodiment of the present application; Figure 2 A three-dimensional schematic diagram of a charging device with a portion of the first housing removed provided in an embodiment of the present application; Figure 3 An exploded schematic diagram of a charging assembly and a telescopic assembly provided in one embodiment of the present application; Figure 4 An exploded schematic diagram of a charging assembly and a telescopic assembly provided in an embodiment of the present application from another perspective; Figure 5 An exploded schematic diagram of a fixing member and a partially damped shaft structure provided in one embodiment of the present application; Figure 6 A schematic diagram of a partially damped shaft structure provided in one embodiment of the present application.

[0051] This application provides a charging device, such as Figure 1 and Figure 2 As shown, the charging device includes: a base 10, a telescopic component 11, the telescopic component 11 includes a fixing member 111, and the fixing member 111 is rotatably connected to the base 10; and a charging component 12, and the charging component 12 is slidably connected to the fixing member 111.

[0052] The base 10 can provide stable support for the telescopic component 11 and the charging component 12 arranged thereon. When in use, the base 10 can be placed on a horizontal surface.

[0053] The charging assembly 12 is connected to the base 10 through the telescopic assembly 11. The telescopic assembly 11 includes at least a fixing member 111. One end of the fixing member 111 is hinged to the base 10, and the charging assembly 12 is slidably connected to the fixing member 111, so that the charging assembly 12 can move along the extension direction of the fixing member 111. The extension direction of the fixing member 111 is parallel to the extension direction of the telescopic assembly. Optionally, a sliding groove is provided on one side surface of the charging assembly 12, and a part of the structure of the fixing member 111 can engage with the sliding groove and move along the sliding groove.

[0054] The charging assembly 12 has a wireless charging surface for charging the mobile electronic device. The charging assembly 12 includes a first wireless charging coil, which is disposed near the wireless charging surface. The mobile electronic device can be wirelessly charged by placing it on or near the wireless charging surface.

[0055] The first wireless charging coil is formed by winding multiple wires together, and the charging process is completed by the mutual conversion of electromagnetic signals and current. The mobile electronic device can be a mobile phone, tablet, etc.

[0056] In some embodiments, the telescopic assembly 11 includes a fixed member 111 and a movable member 112 that is slidably connected to the fixed member 111. One end of the fixed member 111 is hinged to the base 10, and the movable member 112 is connected to the charging assembly 12, allowing the charging assembly 12 to move with the movable member 112. Specifically, the fixed member 111 is provided with a sliding groove extending along its own extension direction, and a portion of the movable member 112 is engaged and can slide within the sliding groove. The movable member 112 is connected to the surface of the charging assembly 12 away from the wireless charging surface.

[0057] One end of the fixing member 111 is hingedly connected to the base 10, allowing the charging assembly 12 to flip relative to the base 10. The charging assembly 12 and the base 10 can be folded together, forming an angle of approximately 0 degrees. This allows the user to easily store the folded charging device or place a mobile electronic device directly on the folded charging assembly 12 for charging. To use the device while charging, the charging assembly 12 can be unfolded relative to the base 10 to any suitable angle.

[0058] Furthermore, the charging assembly 12 includes a magnetic component, which is disposed within the charging assembly 12. The magnetic component can be disposed on the wireless charging surface. The magnetic component refers to a component made of a magnetic material, such as a magnet. Mobile electronic devices generally have materials that can be attracted by the magnetic component.

[0059] In the technical solution of the embodiment of the present application, since the fixing member 111 of the telescopic assembly 11 is rotatably connected to the base 10, the angle of the telescopic assembly 11 relative to the base 10 can be adjusted, thereby adjusting the angle of the charging assembly 12, so that the mobile electronic device is oriented at an angle that is convenient for the user to view and operate, allowing the mobile electronic device to be used while charging. Because the charging assembly 12 is slidably connected to the fixing member 111, the charging assembly 12 can be moved closer to or farther from the base 10, making the charging device suitable for supporting and charging mobile electronic devices of different sizes.

[0060] In some embodiments, as Figures 2 to 4 As shown, the telescopic component 11 also includes a movable part 112 connected to the charging component 12. The movable part 112 is telescopically connected relative to the fixed part 111. The movable part 112 has a first surface opposite to the fixed part 111, and the fixed part 111 has a second surface opposite to the movable part 112. The first surface is provided with a positioning bead 113, and the second surface is provided with a limiting hole 114 that can engage with the positioning bead 113.

[0061] The telescopic assembly 11 also includes a moving member 112. The moving member 112 is fixedly connected to the charging assembly 112 and is telescopically connected relative to the fixed member 111, so that when the charging assembly 12 moves, the moving member 112 can move with it relative to the fixed member 111. Partial surfaces of the moving member 112 and the fixed member 111 face each other. The surface of the moving member 112 facing the fixed member 111 is considered a first surface, and the surface of the fixed member 111 facing the moving member 112 is considered a second surface.

[0062] like Figure 4 As shown, a positioning bead 113 is provided on the first surface. The positioning bead 113 can adopt a press-in positioning bead 113 structure. Exemplarily, the positioning bead 113 includes a ball, an elastic member and a cylinder, the cylinder is fixed on the first surface, an elastic member is provided in the cylinder, one end of the elastic member abuts against the first surface, the other end of the elastic member abuts against the ball, part of the ball is located in the cylinder, and the other part of the ball is exposed from the opening of the cylinder and abuts against the second surface. In the process of the movable member 112 moving relative to the fixed member 111, the ball rolls and is pressed by the second surface, and the elastic member is in a compressed state.

[0063] A retaining hole 114 is defined on the second surface. Retaining hole 114 is located in the path of movement of positioning ball 113 relative to fixing member 111. When the ball moves into retaining hole 114, the elastic member extends, pressing a portion of the ball into retaining hole 114, causing the ball to engage with retaining hole 114, thereby fixing the relative position of movable member 112 and fixing member 111. A user can apply a greater force to disengage the ball from retaining hole 114, allowing the charging assembly 12 to continue moving.

[0064] It is understandable that positioning beads 113 may also be provided on the second surface, and limiting holes 114 may be provided on the first surface, so that the positioning beads 113 cooperate with the limiting holes 114 to fix the relative positions of the movable member 112 and the fixed member 111 .

[0065] Because the first surface is provided with positioning beads 113, the positioning beads 113 help reduce friction between the first and second surfaces during the movement of the movable member 112 relative to the fixed member 111, making the movement process smooth and stable, and can also reduce wear during the telescopic movement, thereby increasing the service life of the telescopic assembly 11. Because the second surface is provided with a limiting hole 114 that can engage with the positioning beads 113, the positioning beads 113 are engaged when they move to the limiting hole 114, so that the movable member 112 is maintained in a specific position, thereby allowing the telescopic assembly 11 to maintain a set length and provide stable support.

[0066] In some embodiments, the first surface is provided with multiple positioning bead groups, and the multiple positioning bead groups are arranged along the telescopic direction of the telescopic component 11. The limiting holes 114 are provided corresponding to a group of positioning bead groups, wherein each positioning bead group includes at least one positioning bead 113.

[0067] In a specific embodiment, a positioning bead group includes two positioning beads 113, and multiple positioning bead groups are arranged on the movable member 112 along the telescopic direction of the telescopic component 11. Optionally, multiple positioning bead groups are evenly arranged along the telescopic direction of the telescopic component 11, and the distance between each two adjacent positioning bead groups is the same. There are two limiting holes 114, and the two limiting holes 114 correspond to the two positioning beads 113 in one positioning bead group. During the movement of the charging component 12 relative to the fixed member 111, the limiting hole 114 on the fixed member 111 can engage with any one of the multiple positioning bead groups, so that the charging component 12 can be fixed at multiple lengths.

[0068] The positioning bead group may include only one positioning bead 113 or more than two positioning beads 113 . The present application does not impose any special limitation on the number of positioning beads 113 included in the positioning bead group.

[0069] In some embodiments, as Figure 3As shown, the second surface is provided with a plurality of limiting hole groups, and the plurality of limiting hole groups are arranged along the telescopic direction of the telescopic component 11 , and the positioning beads 113 are provided corresponding to a group of limiting hole groups, wherein each limiting hole group includes at least one limiting hole 114 .

[0070] In a specific embodiment, a limiting hole group includes two limiting holes 114, and multiple limiting hole groups are provided on the fixing member 111 along the telescopic direction of the telescopic component 11. Optionally, multiple limiting hole groups are evenly arranged along the telescopic direction of the telescopic component 11, and the distance between each two adjacent limiting hole groups is the same. There are two positioning beads 113, and the two positioning beads 113 are respectively provided corresponding to the two limiting holes 114 in a group of limiting hole groups. During the movement of the charging component 12 relative to the fixing member 111, the positioning beads 113 on the moving member 112 can be engaged by any one of the multiple limiting hole groups, so that the charging component 12 can be fixed at multiple lengths.

[0071] The limiting hole group may include only one limiting hole 114 or more than two limiting holes 114 . The present application does not impose any special limitation on the number of the limiting holes 114 included in the limiting hole group.

[0072] As a result, the telescopic component 11 can be stably maintained at multiple lengths, so that the charging component 12 can be suitable for charging and supporting mobile electronic devices of different sizes.

[0073] In some embodiments, as Figures 2 to 4 As shown, the charging component 12 includes a first wireless charging coil and a first shell. The first shell has a accommodating space. The first wireless charging coil and the moving part 112 are both arranged in the accommodating space. The first shell is provided with a groove 121 that connects the accommodating space with the outside world. Part of the fixing part 111 is accommodated in the groove 121 and is slidably connected to the groove 121.

[0074] The charging assembly 12 includes a first wireless charging coil and a first housing. The first housing encloses a housing space, in which the first wireless charging coil and the movable member 112 are both disposed. When the charging assembly 12 is folded, a groove 121 is defined on one side of the first housing near the base 10, with the fixed member 111 and movable member 112 disposed on either side of the surface. The movable member 112 is fixedly connected to the inner wall of the first housing, with the fixed member 111 contacting the positioning bead 113 of the movable member 112 through the groove 121.

[0075] As a result, the charging assembly 12 is driven by the moving member 112 to move relative to the fixing member 111 .

[0076] In some embodiments, as Figure 3 and Figure 4As shown, the inner wall surface of the groove 121 is configured with a sliding groove 122 , and the fixing member 111 is configured with a protruding portion 1111 , which is slidably connected to the sliding groove 122 .

[0077] The inner wall surface of the groove 121 is configured as a slide groove 122 extending along the telescopic direction of the telescopic assembly 11. The fixing member 111 is provided with a protrusion 1111 protruding from the surface, and the protrusion 1111 is accommodated in the slide groove 122 and moves along the slide groove 122.

[0078] As a result, the fixing member 111 can slide in the sliding groove 122 , and the charging assembly 12 can move freely along the extending direction of the sliding groove 122 .

[0079] In some embodiments, as Figures 3 to 6 As shown, the telescopic assembly 11 is rotatably connected to the base 10 via a damping shaft structure 13 .

[0080] The damping shaft structure 13 is a torsion-type hardware shaft that allows the telescopic assembly 11 to rotate and maintain a fixed angle. The damping shaft structure 13 can adopt a nut damping structure, a wrap-type damping structure, etc. This application does not impose any special restrictions on the specific structure for achieving damping.

[0081] Therefore, when adjusting the rotation angle of the charging assembly 12, it is only necessary to directly flip the charging assembly 12 to the desired angle for use, which is convenient and quick to use.

[0082] In some embodiments, as Figures 4 to 6 As shown, the damping shaft structure 13 includes a support member (not shown in the figure), a damping column 131 and a rotating shaft 132 connected to the fixing member 111. The two support members are arranged at a distance from each other on the base 10, and the two damping columns 131 are respectively arranged on the side of the support members away from each other. The two ends of the rotating shaft 132 respectively pass through the support members and are rotatably connected to the support members. The two ends of the rotating shaft 132 respectively have through holes 1321 that can be interference fit with the damping columns 131.

[0083] The damping shaft structure 13 includes a support member, a damping column 131, and a rotating shaft 132. The two support members are spaced apart and disposed on the base 10. The support members have holes through which the rotating shaft 132 can pass and rotate relative to the support members. Damping columns 131 are provided on either side of the support members, separated from each other. Through holes 1321 are provided at each end of the rotating shaft 132. The axial dimension of the damping column 131 is larger than that of the through hole 1321. When the rotating shaft 132 rotates, the damping column 131 is located within the through hole 1321 and forms an interference fit with the through hole 1321, providing damping.

[0084] In one specific embodiment, when the charging assembly 12 is at a 90-degree angle relative to the base 10, the damping column 131 passes through the hole, and the extension direction of the damping column 131 is parallel to the radial direction of the hole. As the charging assembly 12 rotates toward or away from the base 10, the damping column 131 gradually moves away from the hole, until, at a certain angle, the damping column 131 leaves the hole, allowing the charging assembly 12 to fall to one side without being damped.

[0085] Therefore, when the user rotates the shaft 132 by his own strength, the hole on the shaft and the damping column 131 interfere with each other and generate greater friction. After the user stops applying force, the shaft 132 is difficult to rotate under the small pressure of the mobile electronic device, and thus maintains the angle after rotation. It is convenient and quick to use.

[0086] In some embodiments, as Figure 5 As shown, the damping shaft structure 13 further includes a support tube 133 surrounding the rotating shaft 132 , the rotating shaft 132 is connected to the fixing member 111 through the support tube 133 , and the support tube 133 passes through the supporting member and is interference fit with the supporting member.

[0087] The damping shaft structure 13 also includes a support tube 133. The inner wall of the support tube 133 surrounds the rotating shaft 132 and is fixedly connected to the rotating shaft 132. The outer wall of the support tube 133 is fixedly connected to the fixing member 111. The two ends of the support tube 133 respectively pass through the holes of the support member and have an interference fit with the holes of the support member.

[0088] In an optional embodiment, the damping shaft structure 13 includes a rotating shaft 132, a support tube 133 and a support member, the two support members are separated from each other and placed on the base 10, the two ends of the rotating shaft 132 are respectively connected to the two support members, and the support tube 133 surrounds the rotating shaft 132 and is interference fit with the rotating shaft 132.

[0089] Thus, the interference fit between the support tube 133 and the support member further increases the rotational friction, so that the charging assembly 12 can be more stably maintained at the angle required by the user.

[0090] In some embodiments, as Figure 1 and Figure 2 As shown, the base 10 includes a second shell having a first shell wall for placing the charging component 12 . The first shell wall defines a receiving groove 101 , and at least a portion of the charging component 12 can be accommodated in the receiving groove 101 .

[0091] The base 10 includes a second housing. A side wall of the second housing near the charging assembly 12 is considered a first housing wall. A recess is formed on the first housing wall to form a receiving groove 101. The charging assembly 12 is at least partially accommodated in the receiving groove 101.

[0092] Optionally, the depth of the receiving groove 101 is greater than or equal to the thickness of the charging assembly 12. After the charging assembly 12 is placed in the receiving groove 101, the surface of the charging assembly 12 does not protrude from the surface of the first housing wall surrounding the receiving groove 101, making the charging assembly 12 less susceptible to external wear and impact. The receiving groove 101 can protect the charging assembly 12 stored therein.

[0093] The distance between the bottom surface of the receiving groove 101 and the surface of the first housing wall surrounding the receiving groove 101 is the depth of the receiving groove 101. The charging assembly 12 is placed in the receiving groove 101, and the length of the charging assembly 12 in the direction perpendicular to the first housing wall is the thickness of the charging assembly 12.

[0094] In some embodiments, the receiving slot 101 has a side wall surface, a portion of the side wall surface surrounds the contour of the charging component 12 , and another portion of the side wall surface has a gap with the charging component 12 .

[0095] A storage slot 101 is constructed on the first housing wall. This slot 101 has an opening that opens away from the base 10. It also has a bottom surface opposite the opening and a sidewall surface adjacent to the bottom surface. The charging assembly 12 can be inserted into the slot 101 through the opening. A portion of the sidewall surface of the slot 101 surrounds and conforms to the contours of the charging assembly 12. Another portion of the sidewall surface of the slot 101 is spaced apart from the charging assembly 12, creating a gap large enough for a finger to fit. The user can insert a finger into the gap and remove the charging assembly 12, facilitating removal of the second charging assembly 12.

[0096] Thus, the charging assembly 12 can be accommodated and protected by the accommodation slot 101 , which helps to save the space occupied by the charging device and also helps to reduce the degree of wear of the charging assembly 12 .

[0097] In some embodiments, the base 10 also includes a second wireless charging coil, which is arranged in the second shell and close to the first shell wall. In the same projection plane parallel to the first shell wall, the projection of the second wireless charging coil and the projection of the storage slot 101 do not overlap.

[0098] The base 10 also includes a second wireless charging coil. This second wireless charging coil is located within the second housing and adjacent to the first housing wall. The charging assembly 12 provides one wireless charging surface, while the first housing wall provides another. When the charging assembly 12 is folded, the two wireless charging surfaces are adjacent to each other along the extension of the first housing wall. Users can simultaneously charge two mobile electronic devices using both wireless charging surfaces.

[0099] Thus, the user can freely use the charging assembly 12 or the position of the first housing wall adjacent to the charging assembly 12 for charging, which is flexible to use. The charging device can also charge two mobile electronic devices at the same time, which is convenient and fast to use.

[0100] In some embodiments, a socket and / or a plug is provided on the surface of the base 10. The base 10 can be electrically connected to a power source through the socket and / or the plug, and can also be used to perform wired charging for mobile electronic devices through the socket and / or the plug.

[0101] A specific embodiment of the present application is described below.

[0102] The charging assembly 12 provided with magnetic parts is connected to the damping shaft structure 13 to achieve the flipping use of the charging assembly 12.

[0103] The charging assembly 12, equipped with a magnetic element, is connected to the base 10 via the telescopic assembly 11. The telescopic assembly 11 includes a fixed member 111, a movable member 112, a positioning bead 113 provided on the movable member 112, and a retaining hole 114 provided on the fixed member 111. The positioning bead 113 continuously provides stable damping during the sliding process, ensuring a smooth and stable stretching process. The positioning bead 113 comprises a metal ball bearing. The low coefficient of friction between the ball bearing and the fixed member 111 reduces wear between the ball bearing and the fixed member 111, thereby increasing the service life of the telescopic assembly 11.

[0104] The fixing member 111 is provided with a retaining hole 114 corresponding to the ball. When the charging assembly 12 moves, the ball contacts the retaining hole 114 and sinks into it. At this point, a significant amount of pressure is required to retract the ball, allowing the charging assembly 12 to continue moving. This pressure is greater than the pressure applied when the mobile electronic device rests against the charging assembly 12. This allows the charging assembly 12 to be fixed in place when stretched to this position, enabling stable charging of the mobile electronic device and making the charging device suitable for mobile electronic devices of different sizes.
