[0020] The direction in which the data cable extends out of the housing is parallel to the plane where the conductive slip ring is arranged on the circuit board.

[0021] Compared with the prior art, a charging device provided by the present utility model has the following advantages:

[0022] 1. A charging device provided by an embodiment of the present utility model. The charging device includes a main body housing, a telescopic cable component and a circuit component arranged inside the main body housing; the circuit component includes a circuit board and a conductive slip ring arranged on the circuit board and electrically connected to the circuit board. The telescopic cable component includes a coiling housing, a coiling component arranged inside the coiling housing and rotatably connected to the coiling housing, and an electrical connection component arranged on the side of the coiling component close to the circuit component;

[0023] One end of the electrical connection component away from the coiling component contacts the conductive slip ring and is electrically connected to the conductive slip ring; when the electrical connection component rotates with the coiling component, the electrical connection component and the conductive slip ring maintain electrical connection cooperation during relative sliding.

[0024] In this embodiment, there is no need to provide a relatively large electrical connection structure to electrically connect the data line in the telescopic data line assembly and the circuit board inside the charging device as in the prior art. The circuit board in the circuit assembly in this embodiment can be directly connected to the electrical connection assembly in the telescopic line assembly through a conductive slip ring, and there is no need to add an additional electrical connection structure between the telescopic line assembly and the circuit assembly, which greatly reduces the thickness of the telescopic line assembly, reduces the volume of the telescopic line assembly, and realizes the lightweight of the charging device.

[0025] 2. The telescopic wire assembly of the utility model also includes a data wire that is wound up in the wire winding assembly and extends out of the main body shell at one end; the wire winding shell is fixedly connected to a side of the circuit board where the conductive slip ring is set, and the wire winding shell is provided with a clearance channel corresponding to the conductive slip ring; an accommodating space is set in the wire winding shell, the wire winding assembly and the conductive slip ring are both arranged in the accommodating space, and the conductive slip ring is arranged on the side of the wire winding assembly close to the conductive slip ring, and the end of the electrical connection assembly away from the wire winding assembly passes through the clearance channel to contact the conductive slip ring and is electrically connected to the conductive slip ring. By setting the clearance channel, the end of the electrical connection terminal away from the wire winding shell directly passes through the clearance channel to contact the conductive slip ring. The clearance channel can also protect the electrical connection terminal. This avoids the problem that the electrical connection terminal is compressed by other electronic components in the main body shell and deformed when the charging device is bumped.

[0026] 3. The cross-sectional area of the clearance channel of the utility model is equal to or smaller than the cross-sectional area of the winding housing, and the cross-sectional area of the clearance channel is greater than or equal to the cross-sectional area of the conductive slip ring. When the winding assembly rotates relative to the winding housing, the winding assembly drives the electrical connection assembly to rotate together, and the electrical connection assembly slides relative to the conductive slip ring when rotating. Since the cross-sectional area of the clearance channel is greater than or equal to the cross-sectional area of the winding housing, the winding housing will not hinder the electrical connection assembly from sliding relative to the conductive slip ring.

[0027] 4. The winding housing of the utility model comprises a first housing, a second housing and a positioning bolt, the first housing and the second housing are detachably connected, and an accommodating space is formed between the first housing and the second housing;

A positioning hole is provided on the circuit board corresponding to the rotating shaft, and a positioning bolt passes through the positioning hole and is connected to the end of the rotating shaft away from the second shell. The winding assembly can rotate around the circumferential direction of the rotating shaft. When the winding assembly rotates, friction is generated on the rotating shaft, and the friction may cause displacement of the first shell and the second shell, and the positioning bolt passes through the positioning hole and is connected to the end of the rotating shaft away from the second shell, so that the rotating shaft on the second shell is firmly connected to the circuit board.

[0029] 5. The electrical connection assembly of the utility model includes an electrical connection plate and an electrical connection terminal;

[0030] The wire winding assembly further includes a wire winding disc, which includes a wheel disc and a wheel shaft connected to each other. One end of the wheel shaft away from the wheel disc is detachably connected to the electrical connection plate. The electrical connection terminals are arranged on the side of the electrical connection plate away from the wire winding disc and are in contact with the conductive slip ring;

[0031] The surface of the wheel disc on the side close to the first housing, the surface of the wheel shaft, and the surface of the first housing on the side close to the second housing enclose a winding space. The data cable is wound in the winding space, and one end of the data cable is electrically connected to the electrical connection plate. During the winding process, the surface of the wheel disc on the side close to the first housing and the surface of the first housing on the side close to the second housing are used to limit the data cable, preventing the phenomenon that the previous turn of the data cable and the next turn of the data cable are offset during the winding process.

[0032] 6. The electrical connection plate of the present utility model is an electrical connection plate made of a conductive material. Since the electrical connection plate is made of a conductive material, the data cable can be electrically connected to the conductive slip ring through the electrical connection plate and the electrical connection terminals in sequence.

[0033] 7. The electrical connection component of the present utility model includes an insulating plate and electrical connection terminals;

[0034] The wire winding assembly further includes a wire winding disc, which includes a first wheel disc, a second wheel disc, and a wheel shaft connecting the first wheel disc and the second wheel disc. One end of the first wheel disc away from the second wheel disc is detachably connected to the insulating plate. The surface of the first wheel disc on the side close to the second wheel disc, the surface of the wheel shaft, and the surface of the second wheel disc on the side close to the first wheel disc enclose a winding space. The data cable is wound in the winding space, and one end of the data cable is electrically connected to one end of the electrical connection terminals;

[0035] The other end of the electrical connection terminals sequentially passes through the first wheel disc and the insulating plate and is in contact with the conductive slip ring. During the winding process, the surface of the first wheel disc on the side close to the second wheel disc and the surface of the second wheel disc on the side close to the first wheel disc are used to limit the data cable, preventing the phenomenon that the previous turn of the data cable and the next turn of the data cable are offset during the winding process.

[0036] 8. The electrical connection terminals of the present utility model include a main body section, a first bent section, and a second bent section. The main body section is in a sheet shape, and the main body part is accommodated inside the insulating plate. The first bent section is arranged on the side of the main body part close to the wire winding disc, and the first bent section sequentially passes through the insulating plate and the first wheel disc and is electrically connected to the data cable. The second bent section is arranged on the side of the main body part away from the wire winding disc, and the second bent section passes through the insulating plate and is in contact with the conductive slip ring. The volume of the main body section in the electrical connection terminals accounts for a relatively large proportion, and the main body section is accommodated inside the insulating plate, so that the insulating plate can protect the main body section, avoiding the phenomenon that the main body section is bent due to being pressed by other electronic components inside the charging device when the charging device is bumped.

[0037] 9. The insulating board of the present utility model is an insulating board made of insulating material. The insulating board can protect the electrical connection terminals. Since the insulating board is made of insulating material, it has a low cost and can make the electrical connection component lighter.

[0038] 10. One end of the main body housing of the present utility model close to the telescopic wire assembly is provided with an opening for the data line to extend out, and a receiving groove for receiving the output end of the data line is arranged at the end of the main body housing where the opening is provided; the direction in which the data line extends out of the housing is parallel to the plane where the conductive slip ring is arranged on the circuit board.

[0056] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below with reference to the accompanying drawings and implementation examples. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0057] It should be noted that the terms "first" and "second" and the like in the specification and claims of the present invention are used to distinguish different objects rather than to describe a specific order.

[0058] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central 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 terms such as "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. These terms are mainly used to better describe the present utility model and its embodiments, and are not used to limit that the indicated device, element or component must have a specific orientation, or be constructed and operated in a specific orientation.

[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 "mounted", "arranged", "provided with", "connected", "connected to" 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 can be internal communication 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] On existing charging devices, a telescopic data cable assembly is usually provided, and the telescopic data cable assembly can be electrically connected to a circuit board built in the charging device. However, a relatively large electrical connection structure needs to be separately provided inside the existing charging device, and through the electrical connection structure, the telescopic data cable assembly is electrically connected to the circuit board inside the charging device. The existence of the electrical connection structure causes the volume of the telescopic data cable assembly to increase, which is not conducive to the lightweight of the charging device.

[0063] Please refer to Figure 1 and Figure 2 , the first embodiment of the present utility model provides a charging device 10, which includes a main body housing 1, and a telescopic cable assembly 2 and a circuit assembly 3 arranged inside the main body housing 1; the circuit assembly 3 includes a circuit board 32 and a conductive slip ring 31 arranged on the circuit board 32 and electrically connected to the circuit board 32, the telescopic cable assembly 2 includes a cable housing 21, a cable winding assembly 22 arranged inside the cable housing 21 and rotatably connected to the cable housing 21, and an electrical connection assembly 23 arranged on one side of the cable winding assembly 22 close to the circuit assembly 3;

[0064] One end of the electrical connection component 23 away from the winding component 22 is in contact with the conductive slip ring 31 and is electrically connected to the conductive slip ring 31; when the electrical connection component 23 rotates with the winding component 22, the electrical connection component 23 and the conductive slip ring 31 maintain electrical connection cooperation during relative sliding.

[0065] Understandably, in the prior art, an additional electrical connection structure is usually required to electrically connect the data line 24 in the telescopic data line 24 component and the circuit component 3 inside the charging device 10 through the electrical connection structure. In this embodiment, a power source and electrical components (not shown in the figure) are further provided inside the charging device 10. The circuit component 3 is used to be electrically connected to the above-mentioned power source and electrical components or maintain electrical connection cooperation with the electrical connection component 23 during relative sliding. Specifically, the electrical connection component 23 and the conductive slip ring 31 maintain electrical connection cooperation during relative sliding. Preferably, the conductive slip ring 31 is embedded in the circuit board 32, so that the user can visually regard the circuit board 32 and the conductive slip ring 31 as an integral body, which is simple and beautiful. Specifically, the data line 24 is wound around the winding component 22, one end of which is electrically connected to the electrical connection component 23, and the other end extends out of the main body housing 1. When the user wants to supply power to an external electronic device, the end of the data line 24 extending out of the housing can be directly electrically connected to the external electronic device. If there is a distance between the charging device 10 and the electronic device, the user can pull the end of the data line 24 extending out of the housing, forcing the data line 24 wound around the winding component 22 to drive the winding component to rotate. The winding housing 21 is rotatably connected to the winding component 22, that is, after the winding component 22 rotates, the winding housing 21 will not rotate with the winding housing 21. As a possible implementation manner, the winding housing 21 is directly fixedly connected to the circuit board 32. As another possible implementation manner, the winding housing 21 and the circuit board 32 are respectively fixedly connected to the main body housing 1, that is, the winding housing 21 and the circuit board 32 are indirectly fixed. Further, in this embodiment, one end of the electrical connection component 23 away from the winding component 22 is in contact with the conductive slip ring 31 and is electrically connected to the conductive slip ring 31. When the conductive slip ring 31 rotates with the winding component 22, the electrical connection component 23 and the conductive slip ring 31 can maintain electrical connection cooperation during relative sliding, that is, when the data line 24 is electrically connected to the external electronic device, during the process of pulling the data line 24 to increase the distance between the charging device 10 and the electronic device, the charging device 10 can always supply power to the electronic device.

[0066] It should be understood that in this embodiment, there is no need to provide a relatively large electrical connection structure as in the prior art to electrically connect the data line 24 in the telescopic data line 24 assembly and the circuit board 32 inside the charging device 10. The circuit board 32 in the circuit assembly 3 in this embodiment can be directly connected to the electrical connection assembly 23 in the telescopic line assembly 2 through the conductive slip ring 31, and there is no need to add an additional electrical connection structure between the telescopic line assembly 2 and the circuit assembly 3, which greatly reduces the thickness of the telescopic line assembly 2, reduces the volume of the telescopic line assembly 2, and realizes the lightweight of the charging device 10.

[0067] Furthermore, the telescopic wire assembly 2 also includes a data wire 24, one end of which extends out of the main body shell 1 after being wound on the wire winding assembly 22; the wire winding shell 21 is fixedly connected to the side of the circuit board 32 where the conductive slip ring 31 is set, and the wire winding shell 21 is provided with a clearance channel 211 corresponding to the conductive slip ring 31; an accommodating space is set in the wire winding shell 21, and the wire winding assembly 22 and the conductive slip ring 31 are both arranged in the accommodating space, and the conductive slip ring 31 is arranged on the side of the wire winding assembly 22 close to the conductive slip ring 31, and the end of the electrical connection assembly 23 away from the wire winding assembly 22 passes through the clearance channel 211 to contact the conductive slip ring 31 and is electrically connected to the conductive slip ring 31.

[0068] It can be understood that the wire winding housing 21 and the circuit board 32 are fixedly connected, the conductive slip ring 31 is arranged on the wire winding assembly 22, and the wire winding assembly 22 is rotationally connected to the wire winding housing 21. The function of the wire winding housing 21 is not only to protect the wire winding assembly 22, but also to protect the conductive slip ring 31. By providing the clearance channel 211, the end of the electrical connection assembly 23 away from the wire winding assembly 22 directly passes through the clearance channel 211 and contacts the conductive slip ring 31. The clearance channel 211 can also protect the electrical connection assembly 23. It avoids the problem that when the charging device 10 is bumped, the electrical connection assembly 23 is compressed by other electronic components in the main housing 1 and deformed.

[0069] Specifically, the cross-sectional area of the clearance channel 211 is equal to or smaller than the cross-sectional area of the winding housing 21 , and the cross-sectional area of the clearance channel 211 is greater than or equal to the cross-sectional area of the conductive slip ring 31 .

[0070] It should be understood that the clearance channel 211 is used to protect the electrical connection assembly 23, and is used for the electrical connection channel to contact the conductive slip ring 31. Exemplarily, if the cross-sectional area of the clearance channel 211 is smaller than the cross-sectional area of the winding housing 21, and the cross-sectional area of the clearance channel 211 is greater than or equal to the cross-sectional area of the conductive slip ring 31. There is a portion of the winding housing 21 shielding between the winding assembly 22 and the conductive slip ring 31, so that the winding housing 21 can approach the electrical connection assembly 23 and protect the electrical connection assembly 23. In addition, when the winding assembly 22 rotates relative to the winding housing 21, the winding assembly 22 drives the electrical connection assembly 23 to rotate together, and the electrical connection assembly 23 slides relative to the conductive slip ring 31 when rotating. Since the cross-sectional area of the clearance channel 211 is greater than or equal to the cross-sectional area of the winding housing 21, the winding housing 21 will not hinder the electrical connection assembly 23 from sliding relative to the conductive slip ring 31.

[0071] For example, if the cross-sectional area of the clearance channel 211 is equal to the cross-sectional area of the winding housing 21, there is no winding housing 21 blocking the winding assembly 22 and the conductive slip ring 31. The winding housing 21 can achieve better weight reduction. In addition, since the cross-sectional area of the clearance channel 211 is greater than or equal to the cross-sectional area of the winding housing 21, the winding housing 21 will not hinder the electrical connection assembly 23 from sliding relative to the conductive slip ring 31.

[0072] Furthermore, please combine Figure 1 , Figure 4a and Figure 4b The winding housing 21 includes a first housing 212, a second housing 213 and a positioning bolt 215. The first housing 212 and the second housing 213 are detachably connected, and an accommodation space is formed between the first housing 212 and the second housing 213;

[0073] The first shell 212 is detachably connected to the circuit board 32 at a side away from the second shell 213. A rotating shaft 214 is provided on the second shell 213 close to the first shell 212. The circuit board 32 is provided with a positioning hole 322 corresponding to the rotating shaft 214. The positioning bolt 215 passes through the positioning hole 322 and is connected to the end of the rotating shaft 214 away from the second shell 213. The winding assembly 22 can rotate around the circumferential direction of the rotating shaft 214.

[0074] Understandably, the first housing 212 and the second housing 213 are detachable to facilitate the user to repair the coiling assembly 22 or the electrical connection assembly 23 inside the coiling housing 21. When the coiling assembly 22 rotates, a frictional force is generated on the rotating shaft 214, and this frictional force may cause displacement between the first housing 212 and the second housing 213. The positioning bolt 215 passes through the positioning hole 322 and is connected to one end of the rotating shaft 214 away from the second housing 213, so that the rotating shaft 214 on the second housing 213 is firmly connected to the circuit board 32. At the same time, a clamping force can be generated on the first housing 212 during the connection process between the second housing 213 and the circuit board 32, improving the connection stability between the second housing 213 and the first housing 212 and thus avoiding the above displacement phenomenon. In addition, the coiling assembly 22 can rotate around the circumferential direction of the rotating shaft 214, facilitating the user to pull out the data cable 24 from the main housing 1 with a relatively small force.

[0075] Further, in this embodiment, the electrical connection assembly 23 can have various structures to facilitate solving the above technical problems.

[0076] Please refer to Figure 1 and Figure 3a , in one implementation, the electrical connection assembly 23 includes an electrical connection plate 232 and electrical connection terminals 231; the coiling assembly 22 further includes a coiling disk 221, and the coiling disk 221 includes a disk 2211 and a wheel shaft 2212 that are connected to each other. One end of the wheel shaft 2212 away from the disk 2211 is detachably connected to the electrical connection plate 232. The electrical connection terminals 231 are arranged on the side of the electrical connection plate 232 away from the coiling disk 221 and are in contact with the conductive slip ring 31; the surface of the disk 2211 close to the first housing 212, the surface of the wheel shaft 2212, and the surface of the first housing 212 close to the second housing 213 enclose a winding space, and the data cable 24 is wound in the winding space, and one end of the data cable 24 is electrically connected to the electrical connection plate 232. It should be noted that the electrical connection assembly 23 is embedded in one end of the wheel shaft 2212 away from the disk 2211, so that part of the electrical connection assembly 23 protrudes from the end face of the wheel shaft 2212 away from the disk 2211.

[0077] Understandably, in this implementation, the electrical connection assembly 23 includes an electrical connection plate 232 and electrical connection terminals 231. It should be understood that the data cable 24 is flat. When the data cable 24 is wound in the winding space, the first turn is attached to the surface of the wheel shaft 2212, and in subsequent winding, the subsequent turns of the data cable 24 are attached to the surface of the previous turn of the data cable 24. During the winding process, the surface of the disk 2211 close to the first housing 212 and the surface of the first housing 212 close to the second housing 213 are used to limit the data cable 24 to prevent the phenomenon that the previous turn and the subsequent turn of the data cable 24 are displaced during the winding process.

[0078] Specifically, the electrical connection plate 232 is an electrical connection plate 232 of a conductive material. It should be understood that a section of the data line 24 is electrically connected to the electrical connection plate 232, and the electrical connection terminal 231 passes through the clearance channel 211 and contacts the conductive slip ring 31. Specifically, the electrical connection terminal 231 and the conductive slip ring 31 maintain electrical connection and cooperation when sliding relative to each other. Since the electrical connection plate 232 is a conductive material, the data line 24 can be electrically connected to the conductive slip ring 31 through the electrical connection plate 232 and the electrical connection terminal 231 in sequence.

[0079] Please combine Figure 1 and Figure 3b In another embodiment, the electrical connection component 23 includes an insulating plate 233 and an electrical connection terminal 231; the winding component 22 also includes a winding reel 221, the winding reel 221 includes a first wheel 2213, a second wheel 2214 and an axle 2212 connecting the first wheel 2213 and the second wheel 2214, the end of the first wheel 2213 away from the second wheel 2214 is detachably connected to the insulating plate 233, the surface of the first wheel 2213 close to the second wheel 2214, the surface of the axle 2212 and the surface of the second wheel 2214 close to the first wheel 2213 are combined to form a winding space, the data cable 24 is wound in the winding space, and one end of the data cable 24 is electrically connected to one end of the electrical connection terminal 231; the other end of the electrical connection terminal 231 passes through the first wheel 2213 and the insulating plate 233 in sequence and contacts the conductive slip ring 31. It should be noted that the electrical connection component 23 is embedded in one end of the wheel axle 2212 away from the wheel disc 2211 , and a portion of the electrical connection component 23 passes through the first wheel disc 2213 and is exposed to the end surface of the first wheel disc 2213 away from the second wheel disc 2214 .

[0080] It can be understood that in this embodiment, the electrical connection assembly 23 includes an insulating plate 233 and an electrical connection terminal 231. It should be understood that the data cable 24 is flat, and when the data cable 24 is rolled up in the rolling space, the first circle is attached to the surface of the wheel shaft 2212, and when it is subsequently rolled up, the next circle of the data cable 24 is attached to the surface of the previous circle of the data cable 24. During the rolling process, the surface of the first wheel disc 2213 close to the second wheel disc 2214 and the surface of the second wheel disc 2214 close to the first wheel disc 2213 are used to limit the data cable 24, so as to prevent the previous circle of the data cable 24 and the next circle of the data cable 24 from being offset during the rolling process.

[0081] Specifically, the insulating plate 233 is an insulating plate 233 of an insulating material. It should be understood that a section of the data line 24 is electrically connected to one end of the electrical connection terminal 231, and the other end of the electrical connection terminal 231 passes through the clearance channel 211 and contacts the conductive slip ring 31. Specifically, the other end of the electrical connection terminal 231 and the conductive slip ring 31 maintain electrical connection and cooperation when sliding relative to each other. The electrical connection terminal 231 is partially accommodated inside the insulating plate 233, and the insulating plate 233 can protect the electrical connection terminal 231. Since the insulating plate 233 is made of an insulating material, it has a lower cost and can make the electrical connection component 23 lightweight.

[0082] Specifically, please combine Figure 3c The electrical connection terminal 231 includes a main body section 2311, a first bending section 2312 and a second bending section 2313. The main body section 2311 is in a sheet shape, and the main body is accommodated in the insulating plate 233. The first bending section 2312 is arranged on a side of the main body close to the winding reel 221, and the first bending section 2312 passes through the insulating plate 233 and the first wheel 2213 in sequence to be electrically connected to the data line 24. The second bending section 2313 is arranged on a side of the main body away from the winding reel 221, and the second bending section 2313 passes through the insulating plate 233 to contact the conductive slip ring 31.

[0083] It can be understood that the volume of the main body section 2311 in the electrical connection terminal 231 accounts for a relatively large proportion, and the main body section 2311 is accommodated inside the insulating plate 233, so that the insulating plate 233 can protect the main body section 2311 and prevent the main body section 2311 from being compressed by other electronic components inside the charging device 10 and thus bent when the charging device 10 is bumped.

[0084] Specifically, please combine Figure 2 and Figure 5 The direction in which the data line 24 extends out of the housing is parallel to the plane where the conductive slip ring 31 is arranged on the circuit board 32 .

[0085] It can be understood that the plane where the circuit board 32 is provided with the conductive slip ring 31 is set as the circuit board plane 321, and the main body shell 1 is roughly a cube, which has two main planes 13 parallel to the circuit board plane 321 and four side planes 14 perpendicular to the circuit board plane 321. Specifically, the side plane 14 is provided with an opening 11 for the data line 24 to extend out, so that the direction in which the data line 24 extends out of the main body shell 1 is parallel to the plane where the circuit board 32 is provided with the conductive slip ring 31. It should be understood that the data line 24 is wound on the winding assembly 22, and when the direction in which the data line 24 extends out of the main body shell 1 is parallel to the side plane 14, the data line 24 will not be bent or tangled when it extends out of the main body shell 1.

[0086] Further, an opening 11 for the data cable 24 to extend out is formed at one end of the main body housing 1 close to the telescopic cable assembly 2, and a receiving groove 12 for accommodating the output end of the data cable 24 is provided at the end of the main body housing 1 where the opening 11 is formed.

[0087] When the data cable 24 is wound around the cable winding assembly 22, one end of the data cable 24 extending out of the main body housing 1 can be accommodated inside the receiving groove 12, and the receiving groove 12 can protect the data cable 24 to prevent the end of the data cable 24 extending out of the main body housing 1 from being damaged when the charging device 10 is knocked.

[0088] Further, please refer to Figure 1 、 Figure 2 and Figure 6 . The cable winding assembly 22 further includes a moving gear 222 and a locking structure 223. The moving gear 222 is arranged on the side of the cable winding disc 221 close to the second housing 213; the locking structure 223 is clamped between the moving gear 222 and the second housing 213 and is detachably connected to the second housing 213; the locking structure 223 includes a spring piece 2231 and a transmission component 2232. The spring piece 2231 is arranged on the same side of the cable winding disc 221 where the moving gear 222 is arranged. One end of the transmission component 2232 is fixedly connected to the spring piece 2231, and the other end is rotatably connected to the moving gear 222. When the cable winding disc 221 rotates, it drives the moving gear 222 and the transmission component 2232 to move in sequence, and then drives the spring piece 2231 to generate elastic deformation to provide a pre-tightening force for the transmission component 2232 toward or away from one side of the spring piece 2231.

[0089] It should be understood that through the cooperation of the cable winding disc 221 with the moving gear 222 and the locking structure 223, when the data cable 24 wound around the cable winding disc 221 is pulled out to any length, the locking structure 223 can position the data cable 24. When the user wants to unwind the cable, pulling the data cable 24 can drive the cable winding disc 221 to rotate, so that the data cable 24 can be pulled out from the cable winding disc 221. When the user pulls out an appropriate length, the data cable 24 can be directly released, and the cooperation of the cable winding disc 221 with the moving gear 222, the transmission component 2232 and the spring piece 2231 in the locking structure 223 enables the data cable 24 to maintain this length for easy use, effectively improving the practicability of the telescopic cable assembly 2.

[0090] Further, please refer to Figure 7, the transmission component 2232 includes a limit gear 22321 and a swing reset member 22322; the swing reset member 22322 is disposed between the moving gear 222 and the elastic piece 2231, and the limit gear 22321 is disposed on a side of the swing reset member 22322 away from the moving gear 222 and is rotatably connected to the swing reset member 22322; the swing reset member 22322 includes a first fitting unit 22323 that cooperates with the limit gear 22321 and a second fitting unit 22324 that cooperates with the moving gear 222; the pre-tightening force provided by the elastic piece 2231 can cause the second fitting unit 22324 to move in a direction close to the moving gear 222. By the elastic deformation of the elastic piece 2231, a pre-tightening force is applied to the swing reset member 22322, so that the swing reset member 22322 has a tendency to swing to one side. When the data cable 24 is pulled to drive the wire reel 221 and the moving gear 222 to rotate, the moving gear 222 will drive the swing reset member 22322 to move through the second fitting unit 22324, so that the swing reset member 22322 drives the limit gear 22321 to rotate through the first fitting unit 22323. However, due to the existence of the pre-tightening force, the swing reset member 22322 will rebound when it moves a certain distance, so as to contact and cooperate with the tooth groove 2221 of the limit gear 22321 again. The functions of positioning and contraction can be realized by cooperating with different tooth grooves 2221 on the limit gear 22321. It can be seen that the design of using the pre-tightening force provided by the elastic piece 2231 to make the swing reset member 22322 rebound makes the structure of the telescopic cable assembly 2 simpler.

[0091] Further, the moving gear 222 is provided with tooth grooves 2221 corresponding to the second fitting unit 22324. The tooth grooves 2221 include at least three. The pre-tightening force provided by the elastic piece 2231 causes the second fitting unit 22324 to cooperate with the tooth grooves 2221, so that the output end of the data cable 24 stops retracting into the main body housing 1. Through the cooperation between the tooth grooves 2221 and the second fitting unit 22324, on the one hand, the moving gear 222 can drive the swing reset member 22322 to swing, and on the other hand, when the swing reset member 22322 moves a certain distance, it can slide out of the tooth grooves 2221 and rebound through the pre-tightening force, so that the first fitting unit 22323 contacts and cooperates with the tooth grooves 2221 of the limit gear 22321 again, thereby stopping the retraction of the data cable 24 and timely locking. At least three tooth grooves 2221 can ensure that when the moving gear 222 rotates, the swing reset member 22322 will not be in a state of being stationary without cooperating with the tooth grooves 2221 for a long time, thus avoiding the situation where the cable cannot be locked in time. It can be seen that the design of the cooperation between the second fitting member and the tooth grooves 2221 makes the structure of the telescopic cable assembly 2 more reasonable and the use smoother.

[0092] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc. made within the principles of the present utility model shall be included within the protection scope of the present utility model.
