Description

Technical Field

[0001] This application belongs to the technical field of accessories for electronic devices, and particularly relates to a retractable data cable. Background Technology

[0002] Existing retractable data cable products typically have a rotating base in the middle of the data cable, where the data cable is placed and wound into the housing. This structure means that when the user pulls one side of the data cable, the other side of the data cable will extend outwards simultaneously, which cannot meet the user's need to pull only one side of the data cable for use.

[0003] To meet users' needs for pulling only one side of the data cable, a solution has emerged where two sets of retractable cables are stacked inside the housing. While this allows the data cable to be pulled out individually on either side, the two stacked retractable cables nearly double the overall thickness of the product.

[0004] Another solution to the related technology is to store one part of the data cable through a winding mechanism and fix the other part of the data cable inside the housing. The two parts are electrically connected through a circuit board inside the housing. However, the connectors of both parts of the data cable protrude outwards and cannot be stored when not in use. This makes the product larger, the product appearance less neat, and the connectors of the data cable are also prone to bumps and wear. Utility Model Content

[0046] Embodiments of the present application are described below in detail, examples of which are shown in the drawings, wherein the same or similar notations represent the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary only, and are for the purpose of explanation of the present application, and cannot be understood as a limitation of the present application.

[0047] Reference is made below to Figures 1-10 A telescopic data line according to an embodiment of the present application is described.

[0048] As Figures 1-4 shown, the telescopic data line comprises a housing 100, a telescopic storage device 200, a first data line 300, a second data line 400 and a first circuit board 500.

[0049] The telescopic storage device 200 and the first circuit board 500 are installed in the housing 100, and the telescopic storage device 200 is electrically connected to the first circuit board 500. One end of the first data line 300 extends into the housing 100 and is connected to the first circuit board 500, and the other end extends out of the housing 100 for connecting a first device. One end of the second data line 400 is connected to the telescopic storage device 200 and can be wound and stored by the telescopic storage device 200, and the other end extends out of the housing 100 for connecting a second device. The first data line 300 and the second data line 400 are electrically connected through the first circuit board 500 and the telescopic storage device 200.

[0050] As Figure 3 and Figure 4 shown, the first data line 300 comprises a first line body 310 and a first connector 320, and the end of the first line body 310 in the housing 100 is electrically connected to the first circuit board 500, and the end of the first line body 310 outside the housing 100 is connected to the first connector 320. The second data line 400 comprises a second line body 410 and a second connector 420, and the end of the second line body 410 in the housing 100 is connected to the telescopic storage device 200, and the end of the second line body 410 outside the housing 100 is connected to the second connector 420.

[0051] In actual implementation, the first line body 310 and the second line body 410 can be flat data line bodies for easy winding, or can be circular data line bodies, and the present embodiment does not limit this. At the same time, the I / O interface model of the first connector 320 and the second connector 320 includes but is not limited to USB interface, Micro-USB interface, Type-C interface and Lightning interface.

[0052] The housing 100 is provided with a first storage position 110 and a second storage position 120; the first storage position 110 and the second storage position 120 are recessed inward from the outermost surface of the housing 100, respectively for storing the first connector 320 and the second connector 420. In actual implementation, the first storage position 110 and the second storage position 120 can be provided on opposite sides of the housing 100 or on adjacent sides of the housing 100, and this embodiment is not limited thereto.

[0053] The first storage compartment 110 can be matched with the size of the first connector 320 of the first data cable 300, and the size of the second storage compartment 120 can be matched with the size of the second connector 420 of the second data cable 400. This allows the first connector 320 to fit better in the first storage compartment 110 and the second connector 420 to fit better in the second storage compartment 120, so as to store and protect the first connector 320 and the second connector 420.

[0054] In other words, the first wire 310 extends out from inside the housing 100, and the first connector 320 is adapted to be accommodated in the first storage position 110; the second wire 410 extends out from inside the housing 100, and the second connector 420 is adapted to be accommodated in the second storage position 120.

[0055] In some examples, the first storage position 110 and the second storage position 120 are recessed in the outer wall of the housing 100; the first wire 310 extends out from the first storage position 110; and the second wire 410 extends out from the second storage position 120.

[0056] More specifically, the first storage compartment 110 has a first outlet 111 that connects to the interior of the housing 100, and the first wire 310 passes through the first outlet 111 to the outside of the housing 100; the second storage compartment 120 has a second outlet 121 that connects to the interior of the housing 100, and the second wire 410 passes through the second outlet 121 to the outside of the housing 100.

[0057] like Figure 4 As shown, the telescopic storage device 200 is rotatably installed inside the housing 100, including a rotating base 210 and a second circuit board 220. The second circuit board 220 is made into a circular plate shape, the same as the baffle on one side of the rotating base 210, and also serves as the baffle on the other side of the rotating base 210. The end of the second wire 410 is fixed to the axis of the rotating base 210 and electrically connected to the second circuit board 220, so that as the rotating base 210 and the second circuit board 220 rotate, the second wire 410 can be wound and stored in the space between the baffle of the rotating base 210 and the second circuit board 220.

[0058] The elastic reset member, for example, a clockwork spring, exerts an elastic biasing force on the rotating seat 210 to rotate it towards the initial position, so that the rotating seat 210 can be automatically reset after rotation, and thus the second wire body 420 can be automatically wound on the rotating seat 210 for storage.

[0059] The telescopic storage device 200 is installed in a manner that the second circuit board 220 faces the first circuit board 500, and the first circuit board 500 is provided with an electrical connection sliding groove 510 arranged in a ring shape around the rotation axis of the telescopic storage device 200, and the electrical connection terminal of the second circuit board 220 is slidably connected in the electrical connection sliding groove 510, so that the second circuit board 220 always maintains electrical contact with the first circuit board 500 during rotation of the telescopic storage device 200. In this way, the first data line 300 and the second data line 400 are electrically connected through the first circuit board 500 and the telescopic storage device 200.

[0060] The present embodiment can have the following two use scenarios:

[0061] As shown in Figure 2 Scenario one: the user needs to use the telescopic data line.

[0062] The first connector 320 is taken out of the first storage position 110 and pulled out of the first wire body 310, so as to connect the first connector 320 with the interface of the first device; the second connector 420 is taken out of the second storage position 120 and pulled out of the second wire body 410, so as to connect the second connector 420 with the interface of the second device.

[0063] The first device and the second device can be a power supply device and a power consumption device, respectively, for example, the first device and the second device are a power bank and an electronic device to be charged, respectively.

[0064] It should be noted that the first data line 300 and the second data line 400 can be independently operated, for example, when the interface distance between the first connector 320 and the first device is far, only the first connector 320 can be pulled to increase the length of the first wire body 310 outside the shell 100, so that the first connector 320 is connected with the interface of the first device.

[0065] That is, the user can individually pull the first data line 300 or the second data line 400 according to the needs, or simultaneously pull the first data line 300 and the second data line 400, so that the length of the first wire body 310 outside the shell 100 and the length of the second wire body 410 outside the shell 100 are increased.

[0066] As shown in Figure 1 Scenario two: the user does not need to use the telescopic data line.

[0067] The first connector 320 is removed from the interface of the first device to place the first connector 320 into the first receiving position 110; and the second connector 420 is removed from the interface of the second device to place the second connector 420 into the second receiving position 120.

[0068] The user can reduce the length of the first wire body 310 and / or the second wire body 410 outside the shell 100 according to the requirement, so as to place the first connector 320 into the first receiving position 110 and the second connector 420 into the second receiving position 120.

[0069] In the above embodiments, the user can individually extend or retract the first data line 300 or the second data line 400 according to the use requirement, or simultaneously extend or retract the first data line 300 and the second data line 400, which is more flexible in use; the first receiving position 110 receives the first connector 320 and the second receiving position 120 receives the second connector 420, which on the one hand does not occupy the space outside the shell 100, ensuring the small size and beauty of the whole product; and on the other hand effectively protects the connector from damage under the action of bending, pulling and the like.

[0070] As shown in Figure 4 In actual execution, the shell 100 includes an upper shell 131 and a lower shell 132, and the upper shell 131 and the lower shell 132 enclose an inner cavity accommodating the telescopic receiving device 200.

[0071] The lower shell 132 is provided with a fixed shaft 1321, the fixed shaft 1321 can be penetrated through the first circuit board 500, and the telescopic receiving device 200 is rotatably sleeved outside the fixed shaft 1321.

[0072] As shown in Figure 4 and Figure 5 In some embodiments, the side of the first connector 320 away from the first receiving position 110 and the side of the second connector 420 away from the second receiving position 120 are both outside the shell 100.

[0073] In this embodiment, only one side of the first data line 300 and the second connector 420 is exposed, and the remaining part is embedded in the corresponding receiving position of the shell 100, which protects the connector while facilitating the user to take it out, improving the convenience.

[0074] For example, the first connector 320 is magnetically connected with the first receiving position 110, and the second connector 420 is magnetically connected with the second receiving position 120. This can improve the stability of the receiving.

[0075] In actual execution, the first connector 320 and the second connector 420 are both provided with a mounting groove, a magnet is fixed in the mounting groove, and the mounting groove can be sealed by a sealing cover (not shown) to seal the first connector 320 and the second connector 420.

[0076] Meanwhile, the housing 100 is provided with a first magnetic attraction member adjacent to the first receiving position 110, and the first connector 320 is magnetically attracted to the first magnetic attraction member, so that the first connector 320 is magnetically attracted and held in the first receiving position 110. The housing 100 is provided with a second magnetic attraction member adjacent to the second receiving position 120, and the second connector 420 is magnetically attracted to the second magnetic attraction member, so that the second connector 420 is magnetically attracted and held in the second receiving position 120. The first magnetic attraction member and the second magnetic attraction member can be magnets.

[0077] As shown in Figures 5-8 In some embodiments, the housing 100 is provided with a first through hole 141, and the first wire body 310 passes through the first through hole 141 from the inside of the housing 100, and the part of the first wire body 310 between the first through hole 141 and the first connector 320 and outside the housing 100 forms a handle part.

[0078] In this embodiment, the handle part is formed by the first wire body 310, and a handle hole 311 is formed on the part of the housing 100 outside the handle part, so that the user's fingers can pass through the handle hole 311, which is convenient for carrying and does not need to additionally set a hanging rope to realize hand carrying.

[0079] As shown in Figure 7 and Figure 8 Exemplarily, the housing 100 is provided with a second through hole 142 between the first through hole 141 and the first receiving position 110, and the first receiving position 110 is provided with a first wire outlet 111 communicating with the second through hole 142, and the first wire body 310 passes through the second through hole 142 and comes out from the first wire outlet 111. The first receiving position 110 is provided with a first stop portion 112 adjacent to the first wire outlet 111, and the first stop portion 112 is adapted to abut against the end of the first connector 320.

[0080] When the user's fingers are in the handle hole 311 and force is applied to the second data line 400, the tail end of the first connector 320 connected to the first wire body 310 abuts against the stop portion 112 to limit the movement of the connector, so that the size of the handle hole 311 remains fixed.

[0081] Exemplarily, the length of the first wire body 310 is 10-20 cm.

[0082] In this way, the first wire body 310 can be prevented from being too long and messy, and when the user's 1-2 fingers are in the handle hole 311, the first wire body 310 will not be too loose to affect the grip feeling, nor will it be too tight to cause discomfort.

[0083] As shown in Figure 8As shown, the wall surface of the second through hole 142 forms a guide inclined surface 1421 which is in contact with the first line body 310, and the guide inclined surface 1421 extends towards the direction of the first line outlet 111, which is used to guide the first line body 310 of the first data line 300 to the first receiving position 110.

[0084] In this way, the guide inclined surface 1421 can guide the second data line 400 to the first receiving position 110 no matter whether the second data line 400 is stretched or retracted, so as to make the stretching and retracting process smooth.

[0085] As shown in Figure 7 and Figure 9 In some embodiments, the first receiving position 110 is provided with a first line outlet 111 which is communicated to the inside of the shell 100, and the first line body 310 passes out of the first line outlet 111; the second receiving position 120 is provided with a second line outlet 121 which is communicated to the inside of the shell 100, and the second line body 410 passes out of the second line outlet 121.

[0086] The first line outlet 111 and / or the second line outlet 121 is provided with a roller 600 which is in rolling contact with the surface of the first line body 310 and / or the second line body 410.

[0087] In the related art, the shell directly rubs against the data line during the stretching or retracting process of the data line, which may cause the surface of the data line to be worn in the long-term use.

[0088] In the embodiment, the rotation of the roller 600 greatly reduces the resistance of the first line body 310 of the first data line 300 and the second line body 410 of the second data line 400 to move, which facilitates the stretching and retracting of the first line body 310 and the second line body 410, and also reduces the wear during the stretching and retracting process.

[0089] In actual implementation, the first line body 310 and the second line body 410 are both provided with anti-skid lines which can avoid the roller 600 from slipping and reduce the wear.

[0090] In actual implementation, the roller 600 includes a roller shaft 610 and a roller 620 which is arranged on the roller shaft 610, and the roller shaft 610 is perpendicular to the first line body 310 and / or the second line body 410; the rolling surface of the roller 620 is formed with concave-convex stripes in the circumferential direction (as shown in Figure 10
