DETAILED DESCRIPTION

[0021] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0022] Please refer to Figure 1-Figure 3 As shown, the first aspect of the present application proposes a data cable device 1 , which can effectively improve the convenience of automatic winding of the data cable 30 .

[0023] The data cable device 1 includes a base 10, a winding assembly 20, a data cable 30, and an unwinding control assembly 50. The winding assembly 20 includes a winding frame 21 and a driving structure 22; the winding frame 21 is rotatably connected to the base 10; the driving structure 22 is connected to the winding frame 21, and the driving structure 22 is configured to drive the winding frame 21 to rotate relative to the base 10; the data cable 30 is wound on the winding frame 21, and the interface 31 of the data cable can be used to connect to an external device; the unwinding control assembly 50 is electrically connected to the data cable 30, and the unwinding control assembly 50 is configured to generate a control signal when it is obtained that the interface 31 of the data cable is not connected to an external device, and according to the control signal, the driving structure 22 drives the winding frame 21 to rotate relative to the base 10, so as to realize automatic winding of the data cable 30.

[0024] The following combination Figure 1-Figure 13 The specific structure of the data line device 1 is introduced in detail.

[0025] like Figure 1-Figure 3 As shown, the data cable device 1 includes a base 10 , a winding assembly 20 , a data cable 30 and an unwinding control assembly 50 .

[0026] The base 10 is used as a carrier for carrying other components in the data cable device 1. The specific shape of the base 10 is not limited here, and designers can make reasonable designs according to actual needs. Of course, the specific preparation material of the base 10 is not limited here, and designers can make reasonable choices according to actual needs.

[0027] The winding assembly 20 is a structural component used for winding up the data cable 30 (described below) in the data cable device 1 ; the winding assembly 20 includes a winding frame 21 and a driving structure 22 .

[0028] The winding frame 21 is used as a carrier of the data cable 30 and is used to wind the data cable 30. The winding frame 21 is rotatably connected to the base 10. For example, the winding frame 21 can be connected to the base 10 through a bearing but is not limited thereto. The specific structure of the winding frame 21 will be described in detail below.

[0029] The driving structure 22 is a structural member for realizing the winding of the data cable 30, and provides a driving force for the winding of the data cable 30. The driving structure 22 is connected to the winding frame 21, and the driving structure 22 is configured to drive the winding frame 21 to rotate relative to the base 10, that is, the winding frame 21 can rotate relative to the base 10 under the action of the driving structure 22. The specific manifestation of the driving structure 22 will be described in detail below.

[0030] The data cable 30 is a structural component used in the data cable device 1 to realize power or signal transmission. The data cable 30 is wound on the winding frame 21. The specific model of the data cable 30 is not limited here, and the designer can make a reasonable choice according to actual needs. The interface 31 of the data cable can be used to access an external device, wherein the external device can be but not limited to a mobile phone or a charger. It should be noted that the number of interfaces 31 of the data cable can be one or more (more than two); when the number of interfaces 31 of the data cable is one, the type of the one interface can be but not limited to one of a USB interface, a type-C interface and a type-A interface; when the number of interfaces 31 of the data cable is multiple, the types of the multiple interfaces can be the same or different, and the types of the multiple interfaces can be but not limited to one or more of a USB interface, a type-C interface and a type-A interface.

[0031] The release control component 50 is a structural component that can automatically reel in the data cable 30 when the interface 31 of the data cable is in an idle state (i.e., suspended in the air and not connected to an external device). The specific form of the release control component 50 will be described in detail below.

[0032] The release control component 50 is electrically connected to the data line 30 to obtain connection status information of the interface 31 of the data line.

[0033] The release control component 50 is configured to generate a control signal when it is found that the interface 31 of the data line is not connected to an external device. Of course, the release control component 50 may not generate any control signal when it is found that the interface 31 of the data line is connected to an external device, or may generate another control signal different from the above control signal. It should be noted that when the data line 30 is in an initial state where it is not pulled out, the interface 31 of the data line is not connected to an external device, and the release control component 50 will not generate the above control signal. Only when the data line 30 is pulled out under the action of an external force and is in a positioned state after being pulled out, if the interface 31 of the data line is not connected to an external device, will the release control component 50 generate the above control signal.

[0034] The unwinding control assembly 50 enables the driving structure 22 to drive the winding frame 21 to rotate relative to the base 10 according to the control signal, so as to realize automatic winding of the data cable 30 .

[0035] Based on the data cable device 1 in the embodiment of the present application, a release control component 50 is designed. When the release control component 50 obtains that the interface 31 of the data cable is not connected to an external device, a control signal is generated, and the driving structure 22 drives the winding frame 21 to rotate relative to the base 10 according to the control signal, so as to realize the automatic winding of the data cable 30; compared with the related art in which the user manually presses a button to realize the automatic winding of the data cable 30, the user's manual pressing operation is omitted, which can effectively improve the convenience of automatic winding of the data cable 30.

[0036] Furthermore, considering that the driving structure 22 is a structural member that drives the winding frame 21 to rotate relative to the base 10 to achieve the winding of the data cable 30, the specific manifestation of the driving structure 22 can be but is not limited to the following embodiments.

[0037] like Figure 3-Figure 7 As shown, in the first embodiment, the base 10 has a first bearing surface 11; the winding frame 21 includes a rotating shaft 211 and a bracket 212; the rotating shaft 211 is rotatably connected to the base 10; the bracket 212 is located on the side where the first bearing surface 11 of the base 10 is located and is connected to the rotating shaft 211, and the surface of the bracket 212 facing the first bearing surface 11 is provided with an annular guide groove 21211, and the annular guide groove 21211 includes a clamping point groove 21212; the data cable 30 is wound around the rotating shaft 211 and supported on the side of the bracket 212 facing away from the first bearing surface 11. The driving structure 22 includes a locking member 221 and a coil spring 222, and the unlocking control assembly 50 drives the locking member 221 to rotate to disengage from the clamping point groove 21212 according to the control signal, and the rotating shaft 211 rotates under the elastic restoring force of the coil spring 222, thereby realizing the automatic winding of the data cable 30.

[0038] Among them, the first bearing surface 11 can be a plane, a curved surface, or a combination of a plane and a curved surface. The rotating shaft 211 can be connected to the base 10 through a bearing, but not limited thereto. The bracket 212 and the rotating shaft 211 can be detachably connected or non-detachably connected. For example, when the bracket 212 and the rotating shaft 211 are detachably connected, the bracket 212 can be connected to the rotating shaft 211 through one or more of screw connection, card connection or plug connection, etc., but not limited thereto. When the bracket 212 and the rotating shaft 211 are non-detachably connected, the bracket 212 can be connected to the rotating shaft 211 through injection molding or 3D printing to form an integrated structure, or connected to the rotating shaft 211 through bonding. The specific trajectory shape of the annular guide groove 21211 is not limited here, and the designer can make a reasonable design according to actual needs. The card point groove 21212 is a groove section in the annular guide groove 21211 that can achieve a relatively fixed position between the bracket 212 and the base 10. The locking member 221 is a structural member used to achieve relative fixation of the position between the bracket 212 and the base 10. In other words, the bracket 212 and the base 10 are relatively fixed through the locking member 221. The specific structure of the locking member 221 will be described in detail below.

[0039] Specifically, the base 10 also has a second bearing surface 12 arranged opposite to the first bearing surface 11; the locking member 221 is located between the first bearing surface 11 and the bracket 212, the locking member 221 is rotatably connected to the base 10, and part of the locking member 221 is embedded in the annular guide groove 21211; the coil spring 222 is located on the side of the base 10 where the second bearing surface 12 is located, the movable end 2221 of the coil spring is connected to the rotating shaft 211, and the fixed end 2222 of the coil spring is connected to the base 10.

[0040] The locking member 221 can be connected to the base 10 through a bearing, the locking member 221 can also be connected to the base 10 through another rotating shaft 211, or the locking member 221 can be connected to the base 10 through a pin shaft. The specific connection method between the movable end 2221 of the coil spring and the rotating shaft 211, and between the fixed end 2222 of the coil spring and the base 10 is not limited here, and the designer can make a reasonable design according to actual needs; for example, the movable end 2221 of the coil spring can be connected to the rotating shaft 211 by, but not limited to, bonding, clamping or plugging, and the fixed end 2222 of the coil spring can be connected to the base 10 by, but not limited to, bonding, clamping or plugging; the specific connection method between the movable end 2221 of the coil spring and the rotating shaft 211, and between the fixed end 2222 of the coil spring and the base 10 will be described in detail below.

[0041] It should be noted that when the data cable 30 is in the initial state where it is not pulled out, the portion of the locking member 221 embedded in the annular guide groove 21211 (such as the locking protrusion 2212 described below) is located at the position of the clamping point groove 21212 of the annular guide groove 21211, and the position between the bracket 212 and the base 10 is relatively fixed. When the data cable 30 is pulled out under the action of an external force and is in an extended state, the data cable 30 will drive the rotating shaft 211 and the bracket 212 to rotate synchronously, and the synchronous rotation of the rotating shaft 211 and the bracket 212 will drive the portion of the locking member 221 embedded in the annular guide groove 21211 to disengage from the clamping point groove 21212 to allow the locking member 221 to swing, and the locking member 221 swings so that the portion thereof embedded in the annular guide groove 21211 performs periodic motion in the annular guide groove 21211. When the data cable 30 is pulled out to an appropriate length, the portion of the locking member 221 embedded in the annular guide groove 21211 will be located at the position of the card point groove 21212 of the annular guide groove 21211. At this time, the position between the bracket 212 and the base 10 is relatively fixed, and the positioning of the data cable 30 can be achieved after it is pulled out.

[0042] The release control assembly 50 drives the locking member 221 to rotate to the card point groove 21212 that is separated from the annular guide groove 21211 according to the control signal, and the rotating shaft 211 rotates under the elastic restoring force of the coil spring 222, and the rotation of the rotating shaft 211 drives the bracket 212 connected thereto to rotate synchronously, and the rotating shaft 211 and the bracket 212 rotate synchronously to realize the automatic winding of the data line 30. It should be noted that at this time, the locking member 221 can make the part embedded in the annular guide groove 21211 separate from the card point groove 21212 under the action of the release control assembly 50, and swing under the elastic restoring force of the coil spring 222 in the axial direction of the rotating shaft 211, and the swing of the locking member 221 makes the part embedded in the annular guide groove 21211 swing periodically in the annular guide groove 21211 to realize the automatic winding of the data line 30. When the data cable 30 is completely rolled up, the portion of the locking member 221 embedded in the annular guide groove 21211 will be located at the position of the card point groove 21212 of the annular guide groove 21211. At this time, the position between the bracket 212 and the base 10 is relatively fixed, and the positioning of the data cable 30 after rolling up can be achieved, and the data cable 30 is in the above-mentioned initial state again.

[0043] By designing the locking member 221 and the winding spring 222, the release control component 50 generates a control signal when it is detected that the interface 31 of the data cable is not connected to an external device. The release control component 50 drives the locking member 221 to rotate according to the control signal, so that the part of the locking member 221 embedded in the annular guide groove 21211 is disengaged from the card point groove 21212, and the part of the locking member 221 embedded in the annular guide groove 21211 makes a periodic motion in the annular guide groove 21211, thereby realizing the automatic winding of the data cable 30; compared with the related art in which the user manually presses a button to realize the automatic winding of the data cable 30, the manual pressing operation of the user is omitted, and the convenience of the automatic winding of the data cable 30 can be effectively improved. By designing the coil spring 222, when the unlocking control component 50 drives the locking member 221 to rotate to disengage the card point groove 21212 according to the control signal, the data cable 30 is automatically reeled under the action of the elastic restoring force of the coil spring 222 around the axis of the rotating shaft 211, and the structure is simple and the operation is convenient; by arranging the coil spring 222 and the bracket 212 on both sides of the base 10 respectively, on the one hand, the possibility of the data cable 30 being entangled with the coil spring 222 during the reeling process can be effectively avoided, and on the other hand, the space on both sides of the base 10 is fully utilized, which can effectively reduce the volume of the base 10 and the bracket 212, thereby reducing the overall volume of the data cable device 1.

[0044] In a second embodiment, the driving structure 22 may include a driving motor (not shown in the figure), which is installed on the base 10, and the driving shaft of the driving motor is connected to the rotating shaft 211; the release control component 50 generates a control signal when it is detected that the interface 31 of the data cable is not connected to an external device, and controls the driving shaft of the driving motor to rotate according to the control signal to drive the rotating shaft 211 to rotate, thereby realizing automatic winding of the data cable 30.

[0045] Furthermore, if Figure 3-Figure 7As shown, when the driving structure 22 includes a locking member 221 and a coil spring 222, it is considered that the release control component 50 can obtain the connection state of the interface 31 of the data line on the one hand, and can also select whether to drive the locking member 221 to rotate according to the different connection states of the interface 31 of the data line on the other hand, so as to realize automatic winding of the data line 30. In order to make the release control component 50 have the corresponding functions, it is designed that in some embodiments, the release control component 50 includes a controller (not shown in the figure) and a release member 51; the controller is electrically connected to the data line 30, and the controller is used to obtain the connection state of the interface 31 of the data line; the release member 51 is connected to the base 10, and the release member 51 is electrically connected to the controller; the controller generates a control signal when it is obtained that the interface 31 of the data line is not connected to an external device, and controls the release member 51 to drive the locking member 221 to rotate to disengage from the card point groove 21212 according to the control signal. Among them, the release member 51 is used as a power source to drive the locking member 221 to move, and the specific manifestation of the release member 51 will be introduced in detail below. In this design, a controller is designed to obtain the connection status of the interface 31 of the data cable, and the controller generates a control signal when it obtains that the interface 31 of the data cable is not connected to an external device; a release member 51 is designed, and the release member 51 is electrically connected to the controller, so that the controller can control the release member 51 to drive the locking member 221 to rotate to disengage from the card point groove 21212 according to the control signal, so as to realize automatic winding of the data cable 30.

[0046] Furthermore, there are many specific application scenarios in which the controller obtains the connection status of the data line interface 31 to generate the above-mentioned control signal; for example, after the connection between the data line interface 31 and the external device is disconnected, the controller immediately starts to obtain the connection status of the data line interface 31, and immediately generates the above-mentioned control signal when it is obtained that the data line interface 31 is not connected to the external device; or after the connection between the data line interface 31 and the external device is disconnected, the controller delays for a period of time before starting to obtain the connection status of the data line interface 31, and immediately generates the above-mentioned control signal when it is obtained that the data line interface 31 is not connected to the external device; or after the connection between the data line interface 31 and the external device is disconnected, the controller delays for a period of time before starting to obtain the connection status of the data line interface 31, and generates the above-mentioned control signal when it is obtained that the data line interface 31 is not connected to the external device. In the embodiment of the present application, the controller includes a first controller (not shown in the figure) and a second controller (not shown in the figure); the first controller is electrically connected to the data line 30, and the first controller is used to obtain the connection status of the interface 31 of the data line; the second controller is electrically connected to the first controller and the release member 51, and the second controller starts timing when the first controller obtains that the interface 31 of the data line is not connected to the external device, and the second controller generates a control signal when the timing time is greater than the preset time, and the second controller controls the release member 51 to drive the locking member 221 to rotate to the disengagement point groove 21212 according to the control signal. Among them, the first controller can be a PD chip, and the PD chip is integrated with a register that can obtain the connection status of the interface 31 of the data line. The second controller can be an MCU (Microcontroller Unit) or a PLC (Programmable Logic Controller), and the MCU or PLC is integrated with a timer with a timing function. The specific value of the "preset time" is not limited here, and the designer can reasonably design it according to actual needs. For example, the preset time can be but not limited to 5 minutes, 10 minutes, 15 minutes, 20 minutes, 25 minutes or 30 minutes. In this design, a first controller is designed to obtain the connection status of the interface 31 of the data cable; a second controller is designed to start timing when the first controller obtains that the interface 31 of the data cable is not connected to an external device, and to generate a control signal when the timing time is greater than a preset time. On the other hand, the second controller controls the release member 51 to drive the locking member 221 to rotate to disengage from the card point groove 21212 according to the control signal, so as to realize automatic winding of the data cable 30.

[0047] It should be noted that after the data line interface 31 is disconnected from the external device, the first controller immediately starts to obtain the connection status of the data line interface 31. If the data line interface 31 is connected to the external device again during the period when the timing time is less than the preset time, the timing time of the second controller will be reset to zero; until the data line interface 31 is disconnected from the external device again, the second controller restarts the timing from zero. If the timing time is greater than the preset time, the controller controls the release member 51 to drive the locking member 221 to rotate to disengage the card point groove 21212 according to the control signal, and the data line 30 is automatically reeled under the elastic restoring force of the winding spring 222. When the data line 30 is reeled and is in the above-mentioned initial state again, the second controller can generate a judgment signal, and the second controller determines that the data line interface 31 is suspended in the initial state according to the judgment signal. Figure 8 As shown, Figure 8 This is a schematic diagram of the automatic winding process of the data cable 30 with a preset time of 30 minutes. The control logic of the automatic winding of the data cable 30 will not be introduced in detail here.

[0048] Of course, in some other embodiments, a controller can be designed to not only obtain the connection status of the interface 31 of the data line, but also start timing when it is obtained that the interface 31 of the data line is not connected to an external device, and generate the above-mentioned control signal when the timing time is greater than the preset time, and control the release member 51 to drive the locking member 221 to rotate to disengage from the card point groove 21212 according to the control signal.

[0049] Further, it can be understood that the release member 51 serves as a power source for driving the locking member 221 to move. There can be many specific forms of the release member 51, and the specific forms of the locking member 221 are also different for release members 51 with different specific forms.

[0050] like Figure 6-Figure 7As shown, in the first embodiment, the release member 51 is suitable for generating magnetism when powered on, and the locking member 221 has magnetism. When the timing time of the second controller is greater than the preset time, the second controller puts the release member 51 in a powered state according to the control signal, and the locking member 221 rotates to disengage the card point slot 21212 under the action of the magnetic adsorption force of the release member 51. Among them, the locking member 221 can be a permanent magnet, or it can be an electromagnet that generates magnetism when powered on like the release member 51; when the locking member 221 is an electromagnet, the second controller can also put the locking member 221 in a powered state according to the control signal, and at this time, the magnetism of the locking member 221 is opposite to that of the release member 51. It should be noted that when the locking piece 221 rotates to fit into the releasing piece 51 under the action of the magnetic adsorption force of the releasing piece 51, the power to the releasing piece 51 will be cut off immediately, and the locking piece 221 will no longer be affected by the magnetic adsorption force of the releasing piece 51, so that the part of the locking piece 221 embedded in the annular guide groove 21211 can make periodic motion in the annular guide groove 21211 during the automatic winding process of the data cable 30.

[0051] In a second embodiment, the unlocking member 51 is a motor (not shown in the figure). In this case, the locking member 221 is not magnetic, and the rotating shaft 211 of the motor is connected to the locking member 221. When the timing time of the second controller is greater than the preset time, the second controller turns on the motor according to the control signal, and the locking member 221 rotates to disengage from the card point groove 21212 under the action of the driving force of the motor.

[0054] In the second embodiment, the first bearing surface 11 of the base 10 is provided with a snap-fit ​​groove 14, and the release member 51 is snap-fitted into the snap-fit ​​groove 14.
