[0001] The utility model relates to the technical field of electronic device accessories, and particularly relates to a floating charging cable, a charging base and a head-mounted display assembly.

Background Art

[0002] The function of a charging cable is to charge an electronic device. However, the positions of the charging ports of different electronic devices may be different. Even for the same electronic device, the distance between the charging port and the charging cable may change due to external influences.

The head-mounted display is usually placed on a charging base for charging. Since the heights of the charging ports of different head-mounted displays may be different, and when the same head-mounted display is adapted to accessories such as masks of different sizes, the self-structure sizes of the accessories such as masks may affect the height of the charging port of the head-mounted display, resulting in a mismatch between the charging cable and the height of the charging port of the head-mounted display, forming a dislocation, which causes an obstacle to the normal charging of the head-mounted display and affects the stability of the charging process.

[0017] To solve the above technical problems, in another embodiment, the present invention provides a head-mounted display assembly. The head-mounted display assembly includes a head-mounted display device and the above-mentioned charging base, and the head-mounted display device is disposed on the charging base.

[0018] Compared with the prior art, a floating charging cable, a charging base and a head-mounted display assembly of the present invention have the following advantages:

[0019] 1. A floating charging cable in an embodiment of the present utility model includes a first end head, a cable body, and a second end head, which are connected in sequence; the first end head includes a housing, a cavity is provided in the housing, a movable block is arranged in the cavity, and the end of the cable body connected to the first end head is defined as the first connection end. The first connection end extends into the cavity and is connected to the movable block, and the first connection end can move in the direction of approaching or departing from the second end head along with the movable block. By arranging the first connection end to extend into the cavity and be connected to the movable block, and being able to move in the direction of approaching or departing from the second end head along with the movable block, when the movable block moves in the cavity in the direction of approaching or departing from the second end head, since the first connection end is connected to the movable block, the first connection end moves accordingly, driving the cable body and the second end head to move accordingly. As the movable block moves, the distance that the first connection end extends into the cavity is different, and the second end head at the other end of the cable body realizes telescopic floating, and can meet the charging requirements at different distances with different heights. It ensures that within a certain range, the floating charging cable can adjust the height to adapt to charging ports of different heights, avoiding misalignment and making the charging process more stable and reliable.

[0020] 2. In an embodiment of the present utility model, a baffle is provided on one side of the housing facing the second end head, and a limiting plate is arranged on the inner wall of the housing. The baffle, the limiting plate and the inner wall of the housing enclose a cavity. The baffle and the limiting plate become the boundary ends that limit the movement of the movable block in the cavity, playing a constraining role in the movement of the movable block in the direction of approaching or departing from the second end head. The movable block moves in the cavity between the baffle and the limiting plate, causing the second end head to telescopic and float accordingly to cope with charging ports of different heights.

[0021] 3. In an embodiment of the present utility model, the ratio of the depth of the cavity to the height of the movable block is between 3:2 and 3:1. When the ratio of the depth of the cavity to the height of the movable block is 3:2, the displacement range that the movable block can move in the cavity is half of the height of the movable block; when the ratio of the depth of the cavity to the height of the movable block is 3:1, the displacement range that the movable block can move in the cavity is twice the height of the movable block. If the displacement range that the movable block can move is too large, it will result in excessive design redundancy and cause waste of resources; if it is too small, it will not be able to meet the telescopic adjustment requirements of the actual use scenario. By setting the ratio of the depth of the cavity to the height of the movable block between 3:2 and 3:1, it is possible to balance the cost, user experience and adjustment range, achieve a compact structure while ensuring the adjustment range, and improve the user experience.

[0022] 4. In one embodiment of the present utility model, a PCB board is disposed inside the housing. The PCB board is arranged on the side of the limiting plate away from the baffle. The limiting plate is provided with a perforation. The wire body includes a flexible core wire, and the flexible core wire passes through the perforation and is electrically connected to the PCB board. The PCB board provides electrical connection and signal transmission for the floating charging wire. Since the first connection end of the wire body moves with the movable block, the distance between the wire body and the PCB board is not fixed. By setting the wire body to include a flexible core wire, the limiting plate is provided with a perforation, and the flexible core wire passes through the perforation and is electrically connected to the PCB board. The flexible core wire, with its characteristics of being soft, easy to bend and deform, deforms with the change of the distance between the wire body and the PCB board, and always maintains the connection relationship between the wire body and the PCB board, so that the telescoping of the floating charging wire will not affect the stability of the circuit connection and improves the service life of the floating charging wire.

[0023] 5. In one embodiment of the present utility model, the limiting plate is provided with a perforation. The wire body includes a flexible core wire, and the flexible core wire passes through the perforation and is electrically connected to an external PCB board. The PCB board can be arranged outside the floating charging wire in addition to being disposed inside the housing, such as being arranged on the charging base. When the PCB board is arranged outside the floating charging wire, the flexible core wire can also, with its characteristics of being soft, easy to bend and deform, deform with the change of the distance between the wire body and the external PCB board to adapt to the distance change, and always maintain the connection relationship between the wire body and the external PCB board.

[0024] 6. The floating charging wire in one embodiment of the present utility model further includes an elastic member. The elastic member is sleeved on the wire body, and both ends of the elastic member respectively abut against the first end and the second end. By setting the elastic member to be sleeved on the wire body and both ends of the elastic member respectively abut against the first end and the second end to be stressed at both ends, when adjusting the second end to adapt to the charging distance of the charging port, since the second end undergoes displacement relative to the first end, the elastic member deforms to increase the elastic potential energy. After the charging is completed, when the second end is separated from the charging port, the elastic member releases the elastic potential energy and returns to its original state, thereby driving the second end to automatically reset to the initial state.

[0025] 7. The elastic member in one embodiment of the present utility model is a spring. The spring, as the elastic member, has the advantages of simple structure and fast response speed. It can automatically return to the original state after being deformed by an external force, and is more suitable for the application scenario where the floating charging wire needs to be repeatedly adjusted in telescoping for different charging distances.

[0026] 8. The second end in an embodiment of the present utility model includes a first component and a second component. The first component is connected to the wire body, and the first component is magnetically connected to the second component. By setting the magnetic connection between the first component and the second component, the magnetic connection can achieve automatic alignment and adsorption connection, improving the convenience of operation. The second end is designed as a split structure of the first component and the second component. The first component is connected to the wire body, while the second component can be separately arranged on the charging port. The magnetic connection between the two also reduces the wear of the charging interface caused by physical plugging and unplugging, extending the service life of the device interface.

[0027] 9. The first component in an embodiment of the present utility model includes a wiring terminal and a magnetic attraction end. The wiring terminal is connected to the wire body, and the magnetic attraction end is arranged on the side of the first component away from the wire body; the second component includes a plug and a magnetic attraction part connected to each other. The magnetic attraction part is provided with a magnetic attraction surface corresponding to the magnetic attraction end, and the magnetic attraction surface is magnetically connected to the magnetic attraction end. By respectively arranging corresponding magnetic attraction ends and magnetic attraction surfaces on the first component and the second component, the first component and the second component can achieve automatic magnetic alignment and adsorption without precise alignment. The plug can be inserted into the charging port to establish an electrical connection relationship, and at the same time, the open charging port is also reduced, playing a role in dust and water prevention.

[0028] 10. In an embodiment of the present utility model, the insertion direction of the plug is parallel to the magnetic attraction surface. By setting the insertion direction of the plug to be parallel to the magnetic attraction surface, the magnetic attraction surface is evenly stressed in all directions when connected to the magnetic attraction end, is not easy to fall off, and maintains the stability of the connection.

[0029] 11. In an embodiment of the present utility model, the magnetic attraction end is arranged on the side surface of the first component. Since the magnetic attraction end is arranged on the side surface of the first component, and the magnetic attraction part on the second component is provided with a magnetic attraction surface corresponding to the magnetic attraction end, the magnetic attraction end, the magnetic attraction surface, and the plug are arranged in sequence, and the insertion direction of the plug is also a lateral insertion, making the docking direction between the plug and the charging port arranged on the side surface of the electronic device more matched. There is no need to flip and adjust the docking angle of the plug, and the charging can be made more accurate and convenient.

[0030] 12. The charging base in an embodiment of the present utility model includes a base body and the above-mentioned floating charging wire, and the floating charging wire is arranged on the base body. The charging base provided with the floating charging wire can be applicable to electronic devices with different charging heights and supply electric energy to them.

[0031] 13. The head-mounted display assembly in an embodiment of the present invention includes a head-mounted display device and the above-mentioned charging base, and the head-mounted display device is arranged on the charging base. A charging interface is provided on the head-mounted display device. For different head-mounted display devices, the charging interfaces have different heights, or for the same head-mounted display device, the height of the charging interface changes due to the size of accessories such as the face mask. The floating charging cable on the charging base can float up and down telescopically for height adjustment to adapt to the charging interface at an appropriate height, eliminating the height obstacle for charging and making the charging process more stable and reliable.

[0057] In order to make the objectives, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the attached drawings and implementation examples. It should be understood that the specific implementation examples described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0058] It should be noted that when an element is referred to as "fixed to" another element, it can be directly on the other element or there may also be an intermediate element. When an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be an intermediate element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0059] In the present utility model, the orientation or positional relationship indicated by the terms "upper", "lower", "left", "right", "front", "rear", "top", "bottom", "inner", "outer", "middle", "vertical", "horizontal", "lateral", "longitudinal", etc. is based on the orientation or positional relationship shown in the drawings.

[0060] Moreover, in addition to being able to represent the orientation or positional relationship, some of the above terms may also be used to represent other meanings. For example, the term "upper" may also be used to represent a certain attachment relationship or connection relationship in some cases. For those of ordinary skill in the art, the specific meanings of these terms in the present utility model can be understood according to specific circumstances.

[0061] In addition, the terms "installed", "set", "provided with", "connected", "linked" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral structure; it can be a mechanical connection or an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, or there is an internal connection between two devices, elements or components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0062] Please refer to Figures 1 to 6 , the first embodiment of the present utility model provides a floating charging cable 1. The floating charging cable 1 includes a first end 20, a cable body 30 and a second end 40, and the first end 20, the cable body 30 and the second end 40 are connected in sequence; the first end 20 includes a housing 21, the housing 21 is provided with a cavity 211, an active block 212 is arranged in the cavity 211, and the end of the cable body 30 connecting the first end 20 is defined as a first connection end 31. The first connection end 31 extends into the cavity 211 and is connected to the active block 212, and the first connection end 31 can move in the direction of approaching or departing from the second end 40 along with the active block 212.

[0063] Understandably, by setting the first connection end 31 to extend into the cavity 211 and connect with the movable block 212, and it can move along with the movable block 212 in the direction of approaching or departing from the second end 40. When the movable block 212 moves in the cavity 211 in the direction of approaching or departing from the second end 40, since the first connection end 31 is connected to the movable block 212, the first connection end 31 moves accordingly, driving the wire body 30 and the second end 40 to move accordingly. Along with the movement of the movable block 212, the distance that the first connection end 31 extends into the cavity 211 is different, and the second end 40 at the other end of the wire body 30 realizes telescopic floating, and can meet the charging requirements at different distances at different heights. Figure 3 It shows the state where the floating charging wire 1 floats upward and extends out. Figure 4 It shows the natural state where no force is applied to the floating charging wire 1. Figure 5 It shows the state where the floating charging wire 1 floats downward and contracts. Therefore, within a certain range, the floating charging wire 1 can telescopically float up and down, and can adjust the height to adapt to charging ports at different heights, avoiding misalignment and making the charging process more stable and reliable.

[0064] It should be noted that the housing 21 can either adopt an integrally formed structure or be composed of at least two sub-housings combined, and no limitation is made here.

[0065] Please refer to Figure 2 , Figure 3 and Figure 6 . Further, a baffle 213 is provided on the side of the housing 21 facing the second end 40, and a limiting plate 214 is provided on the inner wall of the housing 21. The baffle 213, the limiting plate 214 and the inner wall of the housing 21 enclose to form a cavity 211.

[0066] Understandably, the baffle 213 and the limiting plate 214 become the two boundary ends that limit the movement of the movable block 212 in the cavity 211, and play a constraining role in the movement of the movable block 212 in the direction of approaching or departing from the second end 40. The movable block 212 moves in the cavity 211 between the baffle 213 and the limiting plate 214, so that the second end 40 telescopically floats accordingly to cope with charging ports at different heights.

[0067] Please refer to Figure 3 and Figure 6 . Further, the ratio of the cavity depth of the cavity 211 to the height of the movable block 212 is between 3:2 and 3:1.

[0068] Understandably, the height of the movable block 212 refers to the thickness of the movable block 212 in the telescopic floating direction along the floating charging line 1; the cavity depth of the cavity 211 refers to the cavity height of the cavity 211 in the telescopic floating direction along the floating charging line 1. Define the height of the movable block 212 as h and the cavity depth of the cavity 211 as D. When the ratio D:h of the cavity depth of the cavity 211 to the height of the movable block 212 is 3:2, the movable range of the movable block 212 in the cavity 211 is half of the height of the movable block 212; when the ratio D:h of the cavity depth of the cavity 211 to the height of the movable block 212 is 3:1, the movable range of the movable block 212 in the cavity 211 is twice the height of the movable block 212. If the movable range of the movable block 212 is too large, it will result in excessive design redundancy and waste of resources; if it is too small, it will not be able to meet the telescopic adjustment requirements of the actual use scenario. By setting the ratio D:h of the cavity depth of the cavity 211 to the height of the movable block 212 between 3:2 and 3:1, the cost, user experience, and adjustment range can be balanced, achieving a compact structure and improving the user experience while ensuring the adjustment range.

[0069] Please refer to Figure 3 , further, a PCB board 215 is arranged inside the housing 21. The PCB board 215 is arranged on the side of the limiting plate 214 away from the baffle 213. The limiting plate 214 is provided with a through hole 2141. The wire body 30 includes a flexible core wire 32. The flexible core wire 32 passes through the through hole 2141 and is electrically connected to the PCB board 215.

[0070] Understandably, the PCB board 215 provides electrical connection and signal transmission for the floating charging line 1. Since the first connection end 31 of the wire body 30 moves with the movable block 212, the distance between the wire body 30 and the PCB board 215 is not fixed. By setting the wire body 30 to include a flexible core wire 32 and the limiting plate 214 to be provided with a through hole 2141, and the flexible core wire 32 passes through the through hole 2141 and is electrically connected to the PCB board 215, the flexible core wire 32 deforms with the change of the distance between the wire body 30 and the PCB board 215 due to its soft, easy-to-bend, and easy-to-deform characteristics, always maintaining the connection relationship between the wire body 30 and the PCB board 215, so that the telescopic movement of the floating charging line 1 will not affect the stability of the circuit connection and improve the service life of the floating charging line 1.

[0071] Please combine Figure 7 and Figure 8 , further, the limiting plate 214 is provided with a through hole 2141. The wire body 30 includes a flexible core wire 32. The flexible core wire 32 passes through the through hole 2141 and is electrically connected to the external PCB board 215.

[0072] Understandably, in addition to being disposed inside the housing 21, the PCB board 215 can also be disposed outside the floating charging cable 1, such as on a charging base. When the PCB board 215 is disposed outside the floating charging cable 1, the flexible core wire 32 can also, with its characteristics of being soft, easy to bend, and easy to deform, deform as the distance between the wire body 30 and the external PCB board 215 changes to adapt to the distance change, and always maintain the connection relationship between the wire body 30 and the external PCB board 215.

[0073] Please refer to Figures 3 to 6 , furthermore, the floating charging cable 1 further includes an elastic member 50. The elastic member 50 is sleeved on the wire body 30, and two ends of the elastic member 50 respectively abut against the first end 20 and the second end 40.

[0074] Understandably, in the natural state, the elastic member 50 positions the movable block 212 in the middle of the cavity 211. During use, the movable block 212 can float upward or downward due to the applied force, thereby driving the second end 40 to float up and down. It can adjust the height to adapt to charging ports of different heights, avoid misalignment, and make the charging process more stable and reliable. By setting the elastic member 50 to be sleeved on the wire body 30 and the two ends of the elastic member 50 respectively abut against the first end 20 and the second end 40, when adjusting the second end 40 to adapt to the charging distance of the charging port, since the second end 40 displaces relative to the first end 20, the elastic member 50 deforms to increase the elastic potential energy. After charging is completed, when the second end 40 is separated from the charging port, the elastic member 50 releases the elastic potential energy and returns to its original state, thereby driving the second end 40 to automatically reset to the initial state.

[0075] Please continue to refer to Figures 3 to 6 , furthermore, the elastic member 50 is a spring.

[0076] Understandably, the spring as the elastic member 50 has the advantages of simple structure and fast response speed. It can automatically return to the original state after being deformed by an external force, and is more suitable for the application scenario where the floating charging cable 1 needs to repeatedly adjust the expansion and contraction for different charging distances.

[0077] Please refer to Figure 1 and Figure 2 , furthermore, the second end 40 includes a first component 41 and a second component 42. The first component 41 is connected to the wire body 30, and the first component 41 and the second component 42 are magnetically connected.

[0078] Understandably, by setting the first component 41 and the second component 42 to be magnetically connected, the magnetic connection can achieve automatic alignment and adsorption connection, improving the convenience of operation. The second end 40 is designed as a split structure of the first component 41 and the second component 42. The first component 41 is connected to the wire body 30, while the second component 42 can be separately arranged on the charging port. The magnetic connection between the two also reduces the wear of the physical plugging and unplugging on the charging port and extends the service life of the charging port.

[0079] Please continue to combine Figure 1 and Figure 2 , further, the first component 41 includes a wiring terminal 411 and a magnetic attraction end 412. The wiring terminal 411 is connected to the wire body 30, and the magnetic attraction end 412 is arranged on the side of the first component 41 away from the wire body 30; the second component 42 includes a plug 421 and a magnetic attraction part 422 connected to each other. The magnetic attraction part 422 is provided with a magnetic attraction surface 4221 corresponding to the magnetic attraction end 412, and the magnetic attraction surface 4221 is magnetically connected to the magnetic attraction end 412.

[0080] Understandably, by respectively arranging the corresponding magnetic attraction end 412 and magnetic attraction surface 4221 on the first component 41 and the second component 42, the first component 41 and the second component 42 can achieve automatic magnetic alignment and adsorption without precise alignment. The plug 421 can be inserted into the charging port to establish an electrical connection relationship, and at the same time, the open charging ports are reduced, playing a role in dust and water protection.

[0081] Please continue to combine Figure 1 and Figure 2 , further, the insertion direction of the plug 421 is parallel to the magnetic attraction surface 4221.

[0082] Understandably, defining the insertion direction for the plug 421 to make a charging connection as the insertion direction, by setting the insertion direction of the plug 421 to be parallel to the magnetic attraction surface 4221, the magnetic attraction surface 4221 is evenly stressed in all directions when connected to the magnetic attraction end 412, is not easy to fall off, and maintains the stability of the connection.

[0083] Please combine Figure 9 and Figure 10 , the second embodiment of the present utility model provides a floating charging wire 1, which is different from the floating charging wire 1 provided by the first embodiment of the present utility model in that: the magnetic attraction end 412 is arranged on the side surface of the first component 41.

[0085] Please refer to Figure 1 、 Figure 9 and Figure 11 According to this, the third embodiment of the present invention provides a charging base 100. The charging base 100 includes a base body 110 and the floating charging cable 1 of the first embodiment or the second embodiment of the present invention. The floating charging cable 1 is arranged on the base body 110.

[0086] It can be understood that the charging base 100 provided with the floating charging cable 1 can be applicable to electronic devices with different charging heights and supply electric energy to them.

[0087] Please refer to Figure 12 According to this, the fourth embodiment of the present invention provides a head-mounted display assembly 200. The head-mounted display assembly 200 includes a head-mounted display device 210 and the charging base 100 of the second embodiment of the present invention. The head-mounted display device 210 is arranged on the charging base 100.

[0088] It can be understood that a charging interface 220 is arranged on the head-mounted display device 210. For different head-mounted display devices 210, the charging interfaces 220 have different heights, or for the same head-mounted display device 210, due to the sizes of accessories such as masks, the height of the charging interface 220 of the head-mounted display device 210 changes.

[0089] Compared with the prior art, a floating charging cable, a charging base, and a head-mounted display assembly of the present invention have the following advantages:

[0090] 1. The floating charging cable in an embodiment of the present utility model includes a first end head, a cable body, and a second end head, which are connected in sequence; the first end head includes a housing, a cavity is formed in the housing, a movable block is arranged in the cavity, and the end of the cable body connected to the first end head is defined as the first connection end, the first connection end extends into the cavity and is connected to the movable block, and the first connection end can move in the direction of approaching or departing from the second end head along with the movable block. By setting the first connection end to extend into the cavity and be connected to the movable block, and it can move in the direction of approaching or departing from the second end head along with the movable block. When the movable block moves in the cavity in the direction of approaching or departing from the second end head, since the first connection end is connected to the movable block, the first connection end moves accordingly, driving the cable body and the second end head to move accordingly. With the movement of the movable block, the distance that the first connection end extends into the cavity is different, and the second end head at the other end of the cable body realizes telescopic floating, and can meet the charging requirements at different distances with different heights. It ensures that within a certain range, the floating charging cable can adjust the height to adapt to charging ports with different heights, avoiding misalignment and making the charging process more stable and reliable.

[0091] 2. In an embodiment of the present utility model, a baffle is arranged on one side of the housing facing the second end head, and a limiting plate is arranged on the inner wall of the housing. The baffle, the limiting plate and the inner wall of the housing enclose a cavity. The baffle and the limiting plate become the two boundary ends restricting the movement of the movable block in the cavity, playing a constraining role in the movement of the movable block in the direction of approaching or departing from the second end head. The movable block moves in the cavity between the baffle and the limiting plate, causing the second end head to telescopic and float accordingly to cope with charging ports with different heights.

[0092] 3. In an embodiment of the present utility model, the ratio of the cavity depth of the cavity to the height of the movable block is between 3:2 and 3:1. When the ratio of the cavity depth of the cavity to the height of the movable block is 3:2, the displacement range that the movable block can move in the cavity is half of the height of the movable block; when the ratio of the cavity depth of the cavity to the height of the movable block is 3:1, the displacement range that the movable block can move in the cavity is twice the height of the movable block. If the displacement range that the movable block can move is too large, it will cause excessive design redundancy and waste of resources; if it is too small, it will not be able to meet the telescopic adjustment requirements of the actual use scenario. By setting the ratio of the cavity depth of the cavity to the height of the movable block between 3:2 and 3:1, it is possible to balance the cost, user experience and adjustment range, achieve a compact structure while ensuring the adjustment range, and improve the user experience.

[0093] 4. In an embodiment of the present utility model, a PCB board is disposed inside the housing. The PCB board is arranged on the side of the limiting plate away from the baffle. The limiting plate is provided with a through hole. The wire body includes a flexible core wire, and the flexible core wire passes through the through hole and is electrically connected to the PCB board. The PCB board provides electrical connection and signal transmission for the floating charging wire. Since the first connection end of the wire body moves with the movable block, the distance between the wire body and the PCB board is not fixed. By setting the wire body to include a flexible core wire and the limiting plate to be provided with a through hole, and the flexible core wire passes through the through hole and is electrically connected to the PCB board, the flexible core wire, with its characteristics of being soft, easy to bend, and easy to deform, deforms as the distance between the wire body and the PCB board changes, and always maintains the connection relationship between the wire body and the PCB board, so that the telescoping of the floating charging wire will not affect the stability of the circuit connection, and the service life of the floating charging wire is improved.

[0094] 5. In an embodiment of the present utility model, the limiting plate is provided with a through hole. The wire body includes a flexible core wire, and the flexible core wire passes through the through hole and is electrically connected to an external PCB board. The PCB board can be disposed outside the floating charging wire in addition to being disposed inside the housing, such as being disposed on a charging base. When the PCB board is disposed outside the floating charging wire, the flexible core wire can also, with its characteristics of being soft, easy to bend, and easy to deform, deform as the distance between the wire body and the external PCB board changes to adapt to the distance change, and always maintains the connection relationship between the wire body and the external PCB board.

[0095] 6. The floating charging wire in an embodiment of the present utility model further includes an elastic member. The elastic member is sleeved on the wire body, and two ends of the elastic member respectively abut against the first end and the second end. By setting the elastic member to be sleeved on the wire body and two ends of the elastic member respectively abut against the first end and the second end, when the second end is adjusted to adapt to the charging distance of the charging port, since the second end has a displacement relative to the first end, the elastic member deforms to increase the elastic potential energy. After charging is completed, when the second end is separated from the charging port, the elastic member releases the elastic potential energy and returns to its original state, thereby driving the second end to automatically reset to the initial state.

[0096] 7. The elastic member in an embodiment of the present utility model is a spring. As an elastic member, the spring has the advantages of simple structure and fast response speed. It can automatically return to the original state after being deformed by an external force, and is more suitable for the application scenario where the floating charging wire needs to be repeatedly adjusted in telescoping for different charging distances.

[0097] 8. The second end in an embodiment of the present utility model includes a first component and a second component. The first component is connected to the wire body, and the first component is magnetically connected to the second component. By setting the magnetic connection between the first component and the second component, the magnetic connection can achieve automatic alignment and adsorption connection, improving the convenience of operation. The second end is designed as a split structure of the first component and the second component. The first component is connected to the wire body, while the second component can be separately arranged on the charging port. The magnetic connection between the two also reduces the wear of the charging interface caused by physical plugging and unplugging, extending the service life of the device interface.

[0098] 9. The first component in an embodiment of the present utility model includes a wiring terminal and a magnetic attraction end. The wiring terminal is connected to the wire body, and the magnetic attraction end is arranged on the side of the first component away from the wire body. The second component includes a plug and a magnetic attraction part connected to each other.

The plug can be inserted into the charging port to establish an electrical connection relationship, and at the same time, the open charging port is also reduced, playing a role in dust and water prevention.

[0099] 10. In an embodiment of the present utility model, the insertion direction of the plug is parallel to the magnetic attraction surface. By setting the insertion direction of the plug to be parallel to the magnetic attraction surface, the magnetic attraction surface is evenly stressed in all directions when connected to the magnetic attraction end, not easily falling off, and maintaining the stability of the connection.

[0100] 11. In an embodiment of the present utility model, the magnetic attraction end is arranged on the side of the first component. Since the magnetic attraction end is arranged on the side of the first component, and the magnetic attraction part on the second component is provided with a magnetic attraction surface corresponding to the magnetic attraction end, the magnetic attraction end, the magnetic attraction surface, and the plug are arranged in sequence, and the insertion direction of the plug is also a lateral insertion, making the docking direction between the plug and the charging port arranged on the side of the electronic device more matched. There is no need to flip and adjust the docking angle of the plug, and the charging can be made more accurate and convenient.
