[0010] Optionally, the follower is rotatably connected to the second housing, the follower is provided with a slide rod, and the second housing is also provided with a limiting groove to limit the swing angle of the slide rod to the corresponding position of the take-up track and the release track.

Simultaneously, the receiving groove protects the protruding end, preventing accidental bending or damage to the data cable during storage and carrying. This prevents the end of the data cable from extending outside the outer casing in the stored state, thus extending the lifespan of the data cable. Attached Figure Description

Detailed Implementation

[0028] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0029] like Figures 1 to 3 As shown, this utility model embodiment provides a charging dock 100, including: a housing 110, a data cable 120, a cable reel assembly 130 and a wireless charging module 140 disposed within the housing 110. The cable reel assembly 130 is rotatably connected to the housing 110. The data cable 120 is wound around the cable reel assembly 130, with the inserted end of the data cable 120 electrically connected to the cable reel assembly 130, and the extended end 122 of the data cable 120 extending through an opening 1142 in the housing 110. Outside the housing 110, the cable reel assembly 130 is electrically connected to the wireless charging module 140. The housing 110 is also provided with a receiving groove 112 corresponding to the opening 1142. Inside the housing 110, a first magnetic element 117 corresponding to the receiving groove 112 is provided. The protruding end 122 is provided with a magnetic suction element 1222. When the data cable 120 is stored inside the housing 110, the protruding end 122 can be accommodated in the receiving groove 112, and the first magnetic element 117 and the magnetic suction element 1222 are magnetically attracted.

[0030] Specifically, the data cable 120 is wound around the take-up reel assembly 130 to ensure that the take-up reel assembly 130 can accommodate and support the data cable 120, facilitating the pulling out and retraction of the data cable 120. When the data cable 120 is wound around the take-up reel assembly 130, the inserted end of the data cable 120 is located at the innermost side and is electrically connected to the take-up reel assembly 130. When the extended end 122 is pulled out, the take-up reel assembly 130 is also rotated as the data cable 120 is pulled out. When it is necessary to store the data cable 120 back into the housing 110, simply rotate the take-up reel assembly 130 in the opposite direction to wind the data cable 120. In addition, the extended end 122 is used to connect to a charger, such as a USB port in a vehicle. After powering the wireless charging module 140 through the data cable 120, wireless charging of electronic devices can be achieved.

[0031] The charging dock 100 provided in this embodiment of the application, through a cable reel assembly 130 rotatably connected to the outer shell 110, winds the data cable 120 onto the cable reel assembly 130, allowing the data cable 120 to be pulled out from the opening 1142 to the required length, so as to facilitate power supply to the wireless charging module 140 through the data cable 120, thereby wirelessly charging the electronic device. Furthermore, when it is time to store and carry away after use, the pulled-out data cable 120 can be stored by reversing the rotation of the cable reel assembly 130. After the data cable 120 is stored, its protruding end 122 is housed in the receiving groove 112. Since the housing 110 has a first magnetic element 117 corresponding to the receiving groove 112, and the protruding end 122 has a magnetic attracting element 1222, when the protruding end 122 is located in the receiving groove 112, the magnetic attraction between the first magnetic element 117 and the magnetic attracting element 1222 ensures the stability of the position of the protruding end 122. Simultaneously, the receiving groove 112 protects the protruding end 122, preventing accidental bending or damage to the data cable 120 during storage and transport. This prevents the end of the data cable 120 from extending outside the housing 110 when stored, thus extending the lifespan of the data cable 120.

[0032] The first magnetic component 117 can be a magnet, and the magnetic attracting component 1222 can be an iron sheet wrapped around the protruding end 122 to achieve magnetic attraction. Alternatively, the iron sheet can be directly injection molded into the protruding end 122, which can also achieve the above purpose.

[0033] like Figure 2 , Figure 3 and Figure 4As shown, the take-up reel assembly 130 includes a reel body 132, a guide plate 134 disposed on the reel body 132, and a first circuit board 136 disposed on the side of the reel body 132 opposite to the guide plate 134. A limit post 1144 is disposed inside the housing 110. The reel body 132 is rotatably connected to the limit post 1144. An elastic element (not shown in the figure) is disposed between the reel body 132 and the limit post 1144. A follower 150 corresponding to the guide plate 134 is disposed on the housing 110 to limit the rotation of the reel body 132. The data cable 120 is wound on the reel body 132, and its extended end is electrically connected to the first circuit board 136. The first circuit board 136 is electrically connected to the wireless charging module 140.

[0034] Specifically, the guide plate 134 is located on one side of the plate body 132, the first shorting plate is located on the other side of the plate body 132, and the data cable 120 is wound around the plate body 132 and located on the same side of the plate body 132 as the guide plate 134. Through the limiting post 1144 provided inside the housing 110, the plate body 132 can be rotatably connected relative to the limiting post 1144, and the rotation of the plate body 132 drives the guide plate 134 to rotate synchronously. The housing 110 is provided with a follower 150 corresponding to the guide plate 134, which cooperates with the guide plate 134 during the data cable 120 being pulled out, to engage or disengage with the guide plate 134, thereby limiting the rotation of the plate body 132. The extended end is electrically connected to the first circuit board 136, which is then electrically connected to the wireless charging module 140, thereby supplying power to the wireless charging module 140.

[0035] like Figure 2 , Figure 5 and Figure 7 As shown, the wireless charging module 140 includes a second circuit board 142 and a wireless charging coil 144 that are electrically connected. The wireless charging coil 144 is located on the side of the second circuit board 142 that is away from the first circuit board 136. One of the first circuit board 136 and the second circuit board 142 is provided with a plurality of conductive rings 1422, and the other is provided with a plurality of conductive contacts 138 corresponding to the conductive rings 1422. The conductive rings 1422 and the conductive contacts 138 are connected in a one-to-one correspondence.

[0036] Specifically, the wireless charging coil 144 converts electrical energy into a high-frequency alternating current, thereby generating a high-frequency alternating magnetic field. When the receiving coil in the electronic device approaches the wireless charging coil 144, a current is induced to charge the battery of the electronic device. The wireless charging module 140 is fixedly connected to the outer casing 110, and the take-up reel assembly 130 can rotate relative to the outer casing 110. To ensure the stability of the electrical connection between the two, one of the first circuit board 136 and the second circuit board 142 is provided with multiple conductive rings 1422, and the other is provided with multiple conductive contacts 138 corresponding to the conductive rings 1422. The conductive rings 1422 and conductive contacts 138 are connected one-to-one. For example, conductive rings 1422 can be provided on the first circuit board 136, and conductive contacts 138 can be provided on the second circuit board 142. Alternatively, conductive rings 1422 can be provided on the second circuit board 142, and conductive contacts 138 can be provided on the first circuit board 136.

[0037] like Figure 2 . Figure 3 and Figure 4 As shown, the outer casing 110 includes a first casing 114 and a second casing 116 that are interlocked. A limiting post 1144 is disposed on the first casing 114 or the second casing 116. The disc body 132 includes a tray 1322 and a winding portion 1324 disposed on the tray 1322. The guide disc 134 is engaged with the port of the winding portion 1324. An elastic element is disposed in the winding portion 1324, and both ends of the elastic element are respectively connected to the winding portion 1324 and the limiting post 1144. The tray 1322 is also provided with a clearance hole 1322a so that the insertion end passes through the clearance hole 1322a and is electrically connected to the first circuit board 136.

[0038] Specifically, the data cable 120 is wound on the winding section 1324, and the support plate 1322 supports the data cable 120 to ensure a stable fit between the data cable 120 and the reel body 132. The elastic element can be a spring, with its two ends connected to the winding section 1324 and the limiting post 1144, respectively. When the data cable 120 is pulled, the reel body 132 rotates, causing the spring to tension and accumulate elastic potential energy. When the data cable 120 needs to be retracted, the spring's accumulated elastic potential energy can be used to rotate the reel body 132 in the opposite direction. Through the clearance hole 1322a provided on the support plate 1322, when the inserted end is electrically connected to the first circuit board 136, it can pass through the clearance hole 1322a and be soldered to the pad 1362 on the first circuit board 136, thereby achieving a stable electrical connection.

[0039] like Figure 4 , Figure 5 and Figure 8As shown, the pallet 1322 is provided with a rotating part 1322b that is rotatably connected to the limiting post 1144, the guide plate 134 is provided with a limiting hole 1342 that is rotatably connected to the limiting post 1144, the outer ring of the limiting hole 1342 is provided with a pay-off track 1344 and a take-up track 1346, and the pay-off track 1344 is located on the outer ring of the take-up track 1346. The take-up track 1346 and the pay-off track 1344 are provided with a switching port 1347, a limiting protrusion 1348 is provided at the switching port 1347, and a limiting opening 1348a is provided on the limiting protrusion 1348. The follower 150 can cooperate with the take-up track 1346, the pay-off track 1344 or the limiting opening 1348a respectively.

[0040] Specifically, by providing a rotating part 1322b on the tray 1322 that is rotatably connected to the limiting post 1144, and providing a limiting hole 1342 on the guide plate 134 that is rotatably connected to the limiting post 1144, the rotating part 1322b and the limiting hole 1342, which are far apart, can respectively rotatably engage with the limiting post 1144 to ensure the roundness of the rotation of the plate 132. In addition, through the cooperation of the pay-off track 1344 and the take-up track 1346, during the pulling of the data cable 120, the follower 150 can cooperate with the pay-off track 1344 to ensure the stable pulling out of the data cable 120. When it is necessary to lock the data cable 120 to the current length, the data cable 120 is released, and under the action of the elastic element, the guide plate 134 is reversed, causing the follower 150 to be locked at the limiting port 1348a. When it is necessary to store the data cable 120, gently pull the data cable 120 to rotate the guide plate 134, so that the follower 150 disengages from the limit port 1348a and moves to the cable winding track 1346 through the switching port 1347, thereby realizing the storage of the data cable 120.

[0041] like Figure 6 As shown, the follower 150 is rotatably connected to the second housing 116. The follower 150 is provided with a slide rod 152. The second housing 116 is also provided with a limiting groove 1162 to limit the movement of the follower 150, so as to limit the swing angle of the slide rod 152 to the corresponding positions of the take-up track 1346 and the release track 1344.

[0042] Specifically, the slide bar 152 provided on the follower 150 facilitates its engagement with the take-up track 1346, the release track 1344, and the limiting port 1348a, ensuring stability during engagement. Additionally, the second housing 116 is provided with a limiting groove 1162 to limit the swing angle of the slide bar 152 to the corresponding positions on the take-up track 1346 and the release track 1344, preventing excessive swing angle and deviation, thus ensuring stability during take-up and release of the data cable 120.

[0043] like Figure 8 As shown, the pay-off track 1344 and the take-up track 1346 are elliptical, and the switching port 1347 is located at the transition between the major and minor axes of the ellipse. When the slide bar 152 slides from the minor axis to the major axis, the slide bar 152 slides along the inner wall of the take-up track 1346 or the pay-off track 1344. When the slide bar 152 slides from the major axis to the minor axis, the slide bar 152 slides along the outer wall of the take-up track 1346 or the pay-off track 1344.

[0044] Using the above configuration, when the data cable 120 is pulled out, the guide disk 134 rotates counterclockwise, and the slide bar 152 always moves clockwise relative to the take-up track 1346. When the data cable 120 is stopped being pulled out, under the action of the elastic element, the guide disk 134 starts to rotate clockwise, and the slide bar 152 moves counterclockwise relative to the guide disk 134. The switching port 1347 and the limiting port 1348a need to be set at the position where the slide bar 152 slides along the outside of the release track 1344 when the data cable 120 is pulled out. In this way, when no force is applied to the data cable 120, when the slide bar 152 rotates in the opposite direction relative to the guide disk 134, it will hit the switching port 1347 and the limiting port 1348a, thereby causing the slide bar 152 to slide into the limiting port 1348a and be locked. When it is necessary to stretch the data cable 120 to a longer length, a force is continuously applied to the data cable 120, and the slider 152 will then move counterclockwise relative to the guide disk 134. When the force is no longer applied to the data cable 120, the slider 152 will slide back into the limit port 1348a and be locked.

[0045] Understandably, when it is necessary to retract the data cable 120, gently pull the data cable 120 outwards. The slider 152 moves clockwise out of the limit port 1348a. At this time, care should be taken not to pull it too far to prevent the slider 152 from entering the cable release track 1344. Simply pull the data cable 120 so that the pulled-out length is away from the depth of the limit port 1348a, and the slider 152 will enter the cable take-up track 1346. Then, it slides counterclockwise within the cable take-up track 1346. Under the action of the elastic element, the guide disc 134 rotates clockwise. At this time, the slider 152 slides from the short axis to the long axis. The slider 152 will slide counterclockwise along the inner side of the cable take-up track 1346. Therefore, the slider 152 can avoid entering the cable release track 1344 from the switching port 1347. The disc 132 rotates clockwise, and the data cable 120 is retracted. It should be noted that after the data cable 120 is fully retracted, the slider 152 can be in any position on the cable retraction track 1346. When the data cable 120 is pulled, the slider 152 slides to the switching port 1347 and can then enter the cable release track 1344 from the switching port 1347 to ensure smooth cable release.

[0046] like Figure 8As shown, the end of the limiting protrusion 1348 away from the limiting port 1348a is provided with a first guide arc surface 1348b corresponding to the wire feeding track 1344 and a second guide arc surface 1348c corresponding to the wire taking track 1346.

[0047] Specifically, the first guide arc surface 1348b on the limiting protrusion 1348, corresponding to the cable feeding track 1344, facilitates the smooth feeding of the data cable 120 when it is fully retracted into the housing 110. This allows the slider 152 to slide from any position on the take-up track 1346 to the switching port 1347, and then enter the cable feeding track 1344 along the first guide arc surface 1348b. The second guide arc surface 1348c on the limiting protrusion 1348, corresponding to the take-up track 1346, ensures smooth cable feeding. After the data cable 120 has been pulled out to a certain length, the slider 152 is engaged with the limiting port 1348a to maintain the current extended length. When the data cable 120 is pulled back into the housing 110, the slider 152 disengages from the limiting port 1348a, allowing it to smoothly slide into the take-up track 1346.

[0048] like Figure 3 and Figure 6 As shown, the receiving groove 112 is formed between the first housing 114 and the second housing 116, and a placement groove 1164 is also formed between the first housing 114 and the second housing 116, with the first magnetic element 117 located in the placement groove 1164.

[0049] Specifically, the first housing 114 and the second housing 116 are respectively provided with slots to facilitate the insertion of the first magnetic component 117. After the first magnetic component 117 is inserted, the first housing 114 and the second housing 116 are fastened together to form a complete placement slot 1164, which facilitates the assembly of the first magnetic component 117 and limits the position of the first magnetic component 117 to ensure the stability of the position of the first magnetic component 117. It can be understood that the placement slot 1164 can also be provided on the first housing 114 or the second housing 116 to form a constraint and limit on the first magnetic component 117.

[0050] like Figure 9 As shown, an annular groove 1146 is provided on the outer side of the first housing 114, and a plurality of second magnetic elements 160 are arranged in an array in the annular groove 1146. An annular protective pad 170 is attached to the second magnetic elements 160 and the first housing 114.

[0051] Specifically, the annular groove 1146 provided on the outer side of the first housing 114 facilitates the placement of the second magnetic element 160 within the groove 1146, enabling a magnetic connection between the charging base 100 and the placement surface. This prevents the charging base 100 from shifting or shaking after being placed on the surface, thus ensuring stability during use. An annular protective pad 170 is attached to both the second magnetic element 160 and the first housing 114, preventing the second magnetic element 160 from being exposed and protecting the contact surface. Understandably, in other application scenarios, the second magnetic element 1222 can also attract electronic devices, allowing the charging base 100 to function as a stand for electronic devices and also to charge them, thus improving adaptability during use. The second magnetic element 160 can be a magnet.

[0052] It should be understood that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it.
