The locking member has a locking protrusion protruding towards the second receiving portion. The locking member includes a plurality of locking protrusions, which are spaced apart and arranged around the periphery of the second receiving portion.

[0027] This application proposes a charging device 100.

[0028] Please see Figures 1-8 In this embodiment, the charging device 100 includes a housing 110, a rotating base, and a wire 125. The rotating base is rotatably disposed within the housing 110 and includes a base plate 131, a winding portion 135, and an adapter plate 133. A first receiving portion 130a is formed between the base plate 131, the winding portion 135, and the adapter plate 133. A second receiving portion 140a is provided on the side of the base plate 131 opposite to the first receiving portion 130a to accommodate the elastic reset member 150. The wire 125 extends radially from the rotating base. In the direction, the width of the second accommodating part 140a is greater than the width of the winding part 135. The adapter plate 133 is provided with a wire hole 133a. The winding part 135 is provided with a wiring channel 1353b that connects the first accommodating part 130a and the wire hole 133a. The wire 125 can be wound on the winding part 135 in the first accommodating part 130a. One end of the wire 125 is provided with a connecting terminal 1253. The other end passes through the wiring channel 1353b and the wire hole 133a and is electrically connected to the adapter plate 133.

[0029] In this embodiment, the first accommodating portion 130a and the second accommodating portion 140a are arranged along the axial direction of the rotating seat. The axial direction of the rotating seat refers to the axial direction in which the rotating seat rotates relative to the housing 110; the radial direction of the rotating seat refers to the direction perpendicular to the axial direction of the rotating seat.

[0030] The technical solution of this application provides a second accommodating portion 140a for accommodating the elastic reset member 150 on the side of the substrate 131 opposite to the first accommodating portion 130a, thereby increasing the length of the wire 125 that can be stored in the housing 110. In the prior art, the wire and the elastic reset member are usually arranged in the radial direction of the rotating base. However, due to the size of the housing, the total radial width of the rotating base is limited, which cannot meet the user's need for long-distance charging. To solve this technical problem, this application arranges the second accommodating part 140a for accommodating the elastic reset member 150 on the side of the substrate 131 away from the first accommodating part 130a. This can make full use of the space in the axial direction of the rotating base, so that the radial dimension of the cavity in the rotating base for accommodating the wire 125 (i.e., the radial dimension of the first accommodating part 130a) can be increased without increasing the size of the housing 110 as much as possible. This allows the length of the wire 125 that the rotating base can accommodate to be increased, thus meeting the user's need for long-distance charging. In addition, this arrangement can also increase the size of the second accommodating part 140a, making the width of the second accommodating part 140a greater than the width of the winding part 135, so that a larger size and a more elastic reset member 150 can be placed in the second accommodating part 140a.

[0031] When in use, when the wire 125 housed in the rotating seat is pulled out of the housing 110, the wire 125 will drive the rotating seat to rotate together in the first direction. The rotation of the rotating seat causes the elastic reset member 150 in the second accommodating part 140a to deform. After use, the elastic reset member 150 will reset and drive the rotating seat to rotate in the opposite direction of the first direction, thereby realizing the automatic winding of the wire 125.

[0032] In this embodiment of the application, the charging device 100 includes various devices such as power banks and charging plugs that can retract and extend cables. The following description uses a charging plug as an example of the charging device 100.

[0033] In this embodiment, the number of wires 125 can be one or more; the connection terminal 1253 is disposed outside the housing 110, and the connection terminal 1253 is used to connect to an external electronic device. The connection terminal 1253 can be any one of a Micro-USB connector, a USB Type-C connector, or a Lightning connector.

[0034] In some embodiments, the elastic reset member 150 is a coil spring, which is coaxially arranged with the rotating seat. It should be noted that the elastic reset member 150 can also be other elastic components capable of driving the rotating seat to rotate and wind the wire 125.

[0035] In some embodiments, the charging device 100 further includes a locking mechanism for locking the rotating seat to the housing 110 to prevent the rotating seat from rotating relative to the housing 110. Understandably, the locking mechanism has a locked state and an unlocked state. In use, after the wire 125 is pulled out of the housing 110 from the rotating seat to a preset length, the locking mechanism is in the locked state, locking the rotating seat and the housing 110, thereby preventing the wire 125 from being wound back into the rotating seat under the action of the elastic reset member 150. During the winding of the wire 125, the locking mechanism is in the unlocked state, allowing the elastic reset member 150 to reset and drive the rotating seat to rotate in the opposite direction of the first direction to wind the wire 125.

[0036] Please see Figure 5 In some embodiments, the locking mechanism and the second receiving portion 140a are located on the same side of the substrate 131. In existing charging devices, there is generally some unused space around the locking mechanism inside the housing (around the radial direction of the rotating seat). This embodiment can make full use of this unused space to arrange the elastic reset member 150, so that the radial dimension of the cavity in the rotating seat for accommodating the wire 125 can be increased without increasing the size of the housing 110, thereby improving the structural compactness of the charging device 100.

[0037] In some embodiments, the locking mechanism includes a locking member 161 and a fastener. The locking member 161 is rotatable relative to the housing 110, and the fastener is fixedly connected to the base plate 131. The locking member 161 has a locking protrusion 1611 protruding towards the second receiving portion 40a. The fastener includes a plurality of locking protrusions 162, which are spaced apart and arranged around the periphery of the second receiving portion 140a. The locking protrusions 162 may be arc-shaped strips extending circumferentially along the second receiving portion 140a. A locking groove 162a is formed between two adjacent locking protrusions 162. When the rotating seat is in the locked state, the locking protrusion 1611 is engaged in the locking groove 162a. Compared to setting the fastener at the corresponding position in the middle of the second receiving portion 140a, setting the fastener on the periphery of the second receiving portion 140a increases the distance between the locking member 161 and the central axis of the rotating seat, which increases the torque. This allows the locking mechanism to securely lock the rotating seat with only a small locking force, thus improving locking stability.

[0038] In the above embodiments, the locking protrusion 162 is prone to deformation due to thermal expansion and contraction during the injection molding process, which reduces the overall locking accuracy of the locking device and thus affects the locking effectiveness of the locking mechanism.

[0039] In order to prevent the locking protrusion 162 from deforming due to thermal expansion and contraction during the injection molding process, in some embodiments, the locking protrusion 162 is connected to the outer wall of the second receiving portion 140a, and the side surface of the substrate 131 opposite to the second receiving portion 140a is provided with a groove 131a corresponding to the locking protrusion 162, and the groove 131a extends into the locking protrusion 162.

[0040] Please see Figure 7 In some embodiments, the winding section 135 includes a bushing 1351 and a connecting wall 1353. The bushing 1351 protrudes from the side of the substrate 131 away from the second receiving portion 140a. The connecting wall 1353 surrounds the outside of the bushing 1351 and forms a cable routing channel 1353b with the bushing 1351 at a distance. The end of the connecting wall 1353 away from the second receiving portion 140a is fixedly connected to the adapter plate 133. In this embodiment, the adapter plate 133 is disposed on the side of the connecting wall 1353 away from the second receiving portion 140a. The adapter plate 133 is away from the vibration source, the elastic reset member 150. This arrangement can, on the one hand, prevent the adapter plate 133 from detaching from the winding section 135 due to vibration during the winding and unwinding process; on the other hand, it can prevent the heat generated by the high-speed rotation of the elastic reset member 150 during the winding and unwinding process from being transferred to the adapter plate 133.

[0041] Please continue reading. Figure 7 In some embodiments, the connecting wall 1353 has a proximal end and a distal end. The proximal end is connected to the bushing 1351, and the distal end extends spirally from the proximal end toward the direction away from the bushing 1351. In this embodiment, by providing a spiral connecting wall 1353 on the outer periphery of the bushing 1351, it is easier to wind and fix the inner end of the wire 125, and to avoid the wire 125 becoming loose during pulling.

[0042] In the above embodiment, further, along the radial direction of the rotating seat, the width of the cavity of the second accommodating portion 140a is greater than the width of the winding portion 135. Although the connecting wall 1353 occupies part of the radial dimension of the rotating seat, the dimension it occupies is less than the radial width of the second accommodating portion 140a. Therefore, the overall radial dimension of the rotating seat is still increased, and the length of the wire 125 that the rotating seat can accommodate is increased.

[0043] Based on the above embodiments, in some embodiments, the winding portion 135 is integrally formed with the substrate 131, the connecting wall 1353 is provided with a plurality of first connecting holes 1353a extending along its axial direction, the adapter plate 133 is provided with a plurality of second connecting holes corresponding one-to-one with the first connecting holes 1353a, and the bolt can pass through the second connecting holes and the first connecting holes 1353a in sequence to fix the adapter plate 133 to the winding portion 135.

[0044] In some embodiments, along the axial direction of the rotating seat, the width of the elastic reset member 150 is less than the height of the cavity of the second receiving portion 140a. This arrangement allows for a gap between the elastic reset member 150 and the cover plate 143, preventing the cover plate 143 from interfering with the deformation / reset process of the elastic reset member 150 through friction, thereby affecting the smoothness of the extension and retraction of the wire 125.

[0045] In some embodiments, a gap is provided between the resilient reset member 150 and the enclosure wall 141. Similarly, this arrangement can prevent frictional interference between the enclosure wall 141 and the resilient reset member 150.

[0046] In this embodiment of the application, a rotating shaft 185 is provided inside the housing. The rotating shaft 185 is fixed relative to the housing 110, and the rotating seat is rotatably sleeved on the rotating shaft 185.

[0047] Please see Figure 4 , Figure 5 and Figure 6 In some embodiments, the charging device 100 further includes a charging module 190 and a fixing plate 170. The fixing plate 170 is fixed relative to the housing 110. The adapter plate 133 and the charging module 190 are disposed on both sides of the fixing plate 170 and electrically connected through the fixing plate 170. The bushing 1351 is provided with a shaft hole. The adapter plate 133 and the fixing plate 170 are respectively provided with a first through hole and a second through hole. In this embodiment, the first through hole is located in the middle of the adapter plate 133 and communicates with the wire through hole 133a (e.g., Figure 7 (As shown); the rotating shaft 185 has a first end and a second end. The first end of the rotating shaft 185 is fixed relative to the housing 110, and the second end of the rotating shaft 185 extends into the second receiving portion 140a through the second through hole, the first through hole and the shaft hole in sequence. One end of the elastic reset member 150 is connected to the second end of the rotating shaft 185, and the other end of the elastic reset member 150 is fixed in the second receiving portion 140a.

[0048] In the prior art, the elastic reset member is located in the middle of the winding section, and the center of mass of the rotating seat coincides with the axis of rotation, resulting in minimal wobbling during rotation. However, in this application, the elastic reset member 150 is offset, causing the center of mass of the rotating seat to deviate towards the elastic reset member 150. This results in a shift in the torque path, and the torque that originally acted directly on the winding section 135 now needs to be transmitted through the substrate 131. This causes an additional centrifugal torque to be generated when the rotating seat rotates, which may lead to a larger wobbling amplitude. Consequently, the wear rate of the connecting parts connected to the first end of the bushing 1351 is accelerated.

[0049] In order to avoid the wear rate of the connecting parts connected to the first end of the bushing 1351 being accelerated when the rotating seat rotates due to the bias of the elastic reset member 150, in some embodiments, the first end of the rotating shaft 185 is provided with a support platform 1851, the support platform 1851 is located in the second through hole, and the end of the bushing 1351 away from the second receiving portion 140a abuts against the support platform 1851.

[0050] Please see Figure 6 and Figure 7 In some embodiments, the adapter plate 133 includes a first plate body and a first electrical connection portion 1331 electrically connected to the wire 125. A first receiving portion 130a is formed between the substrate 131, the winding portion 135, and the first plate body. The first electrical connection portion 1331 is disposed on the side surface of the first plate body opposite to the first receiving portion 130a. Multiple first electrical connection portions 1331 may be provided; in this embodiment, the number of first electrical connection portions 1331 is three. Each first electrical connection portion 1331 includes multiple conductive springs; in this embodiment, each first electrical connection portion 1331 includes five conductive springs. The fixing plate 170 includes a second plate body and a second electrical connection portion 171, and a mounting is formed between the second plate body and the first plate body. The second electrical connection part 171 is provided on the side of the second plate facing the first plate. The first electrical connection part 1331 and the charging module 190 are electrically connected through the second electrical connection part 171. The second electrical connection part 171 includes, for example, a plurality of concentrically arranged annular conductive parts. The plurality of annular conductive parts are spaced apart and arranged around the outside of the second through hole. In this embodiment, the number of annular conductive parts is five. The annular conductive parts are in contact with the conductive spring piece one by one. In addition, along the direction away from the second receiving part 140a, the bushing 1351 is higher than the connecting wall 1353. The end of the bushing 1351 passes through the first through hole of the adapter plate 133 and abuts against the support platform 1851, and / or the surface of the support platform 1851 is higher than the surface of the second plate.

[0051] Please see Figure 6 In some embodiments, the charging device 100 further includes a bracket 181, a rotating seat and a charging module 190 respectively disposed on both sides of the bracket 181, a fixing plate 170 fixed to the bracket 181 and located between the bracket 181 and the adapter plate 133, a first end of a rotating shaft 185 passing through a second through hole in the fixing plate 170 and fixedly connected to the bracket 181, and a second end of the rotating shaft 185 having a positioning part 1852, the positioning part 1852 extending entirely or partially out of the second receiving part 140a and connected to the inner wall of the housing 110. In this embodiment, the bracket 181 and the housing 110 cooperate to form a rotation constraint structure for the rotating seat, which can reduce the swaying amplitude of the rotating seat.

[0052] Please continue reading. Figure 6In some embodiments, the second end of the rotating shaft 185 is provided with a slot 185a, which extends from the rotating shaft to the positioning part 1852 and passes through the positioning part 1852. The inner end of the elastic reset member is embedded in the slot 185a. The inner wall of the housing 110 is provided with a limiting member, which is shaped like a "θ". The limiting member includes a limiting ring and a locking strip in the limiting ring. The positioning part is inserted into the limiting member, wherein the locking strip in the limiting member engages with the slot 185a on the positioning part 1852.

[0053] In some embodiments, the diameter of the positioning part 1852 is smaller than the diameter of the rotating shaft 185, and the end face of the second end of the rotating shaft 185 abuts against the end face of the limiting ring. This arrangement can improve the connection stability between the rotating shaft 185 and the housing 110.

[0054] In the above embodiments, the bracket 181 and the housing 110 can be fixed by screwing, snap-fitting, or welding. In a specific embodiment, the bracket 181 is provided with a buckle 183 that mates with the inner wall of the housing 110, and the bracket 181 and the housing 110 are fixed by snap-fitting the buckle 183.

[0055] In some embodiments, the height of the second receiving portion 140a is less than or equal to the height of the locking mechanism along the axial direction of the rotating seat. This arrangement prevents the size of the housing 110 from increasing along the axial direction of the rotating seat, thus ensuring that an increase in the length of the wire 125 does not lead to an increase in the size of the housing 110.

[0056] In some embodiments, the depth of the cavity of the second receiving portion 140a is greater than the depth of the cavity of the rotating seat along the axial direction. This arrangement ensures that there is sufficient axial space in the second receiving portion 140a to accommodate an elastic reset member 150 of a certain width, thereby enabling the elastic reset member 150 to provide sufficient elasticity to achieve the winding of the wire 125.

[0057] In some embodiments, the width of the second receiving portion 140a is smaller than the width of the rotating seat in the radial direction. This arrangement avoids the second receiving portion 140a occupying too much space in the housing 110, thereby maximizing the radial dimension of the cavity in the rotating seat for accommodating the wire 125 without increasing the size of the housing 110.

[0058] Please see Figure 5 , Figure 7 and Figure 8In some embodiments, the rotating seat further includes a surrounding wall 141 and a cover plate 143. The surrounding wall 141 protrudes from the side of the base plate 131 facing away from the first receiving portion 130a. The cover plate 143 covers the end of the surrounding wall 141 away from the base plate 131. The second receiving portion 140a is formed by the base plate 131, the surrounding wall 141 and the cover plate 143. The end of the surrounding wall 141 away from the base plate 131 is provided with a plurality of recesses 141a. The plurality of recesses 141a are arranged sequentially at intervals along the circumference of the surrounding wall 141. The edge of the cover plate 143 is provided with a plurality of protrusions 1431, and the protrusions 1431 are correspondingly provided in the recesses 141a.

[0064] In some embodiments, the housing 110 is further provided with one or more USB ports 123, which are electrically connected to the charging module 190. By providing USB ports 123 on the housing 110, the charging device 100 can charge multiple electronic devices simultaneously.

[0065] In some embodiments, the housing 110 includes an upper housing 110 and a lower housing 110. A rotating seat, a second receiving portion 140a, and a locking mechanism are located in the upper housing 110, and a charging module 190 is located in the lower housing 110. A limiting member is disposed on the axial side of the upper housing 110 facing the second receiving portion 140a. During the assembly of the charging device 100, the lower housing 110 can be assembled sequentially with the charging module 190, the bracket 181, the rotating shaft 185, the fixing plate 170, and the rotating seat, and then the upper housing 110 can be assembled.

[0066] This application embodiment optimizes the spatial layout of the components inside the housing 110 of the charging device 100. Without changing the radial width of the rotating base, the width of the coiled wire in the radial direction of the rotating base can be increased by more than 13mm. The length of the wire 125 that the rotating base can hold can be increased by 30cm, which is 42.8% longer than the 70cm wire length of the existing products. This can basically meet the user's needs for long-distance charging.
