DETAILED DESCRIPTION

[0023] In order to make the purpose, technical solutions and advantages of this application more clearly understood, the present application is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0024] 1 to 3 , a first aspect of the present application provides a data cable device 1 , which can effectively improve the convenience of automatically winding a data cable 30 .

[0025] The data cable device 1 includes a base 10, a winding assembly 20, a data cable 30, and a release control assembly 50. The winding assembly 20 includes a winding frame 21 and a drive structure 22; the winding frame 21 is rotatably connected to the base 10; the drive structure 22 is connected to the winding frame 21 and is configured to drive the winding frame 21 to rotate relative to the base 10; the data cable 30 is wound around the winding frame 21, and the data cable interface 31 can be used to connect to an external device; the release control assembly 50 is electrically connected to the data cable 30 and is configured to generate a control signal when it detects that the data cable interface 31 is not connected to an external device. Based on the control signal, the release control assembly 50 causes the drive structure 22 to drive the winding frame 21 to rotate relative to the base 10, thereby achieving automatic winding of the data cable 30.

[0026] The specific structure of the data line device 1 is described below in conjunction with FIG. 1 to FIG. 13 .

[0027] As shown in FIG. 1 to FIG. 3 , the data cable device 1 includes a base 10 , a winding assembly 20 , a data cable 30 , and a release control assembly 50 .

[0028] The base 10 serves as a carrier for 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 based on actual needs. Of course, the specific preparation material of the base 10 is not limited here, and designers can make reasonable choices based on actual needs.

[0029] The winding assembly 20 is a structural component used for winding 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 .

[0030] The winding frame 21 serves as a carrier for 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 via, but is not limited to, a bearing. The specific structure of the winding frame 21 will be described in detail below.

[0031] The drive structure 22 serves as a structural component for rewinding the data cable 30 and provides the driving force for this process. The drive structure 22 is connected to the winding frame 21 and is configured to drive the winding frame 21 to rotate relative to the base 10. In other words, the drive structure 22 enables the winding frame 21 to rotate relative to the base 10. The specific embodiment of the drive structure 22 will be discussed in detail below.

[0032] The data cable 30 is a structural component used to realize power or signal transmission in the data cable device 1. 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 connect to 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 (two or more); 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.

[0033] 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 and not connected to an external device). The specific form of the release control component 50 will be introduced in detail below.

[0034] 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.

[0035] The release control component 50 is configured to generate a control signal when it detects that the data cable interface 31 is not connected to an external device. However, the release control component 50 may not generate any control signal when it detects that the data cable interface 31 is connected to an external device, or may generate a control signal different from the aforementioned control signal. It is important to note that when the data cable 30 is in its initial, unextended state and the data cable interface 31 is not connected to an external device, the release control component 50 will not generate the aforementioned control signal. The release control component 50 will only generate the aforementioned control signal when the data cable 30 is pulled out under external force and in its positioned state after being pulled out, and when the data cable interface 31 is not connected to an external device.

[0036] The release control assembly 50 controls 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 .

[0037] 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 detects 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 automatic winding of the data cable 30; compared with the related art in which the user manually presses a button to realize automatic winding of the data cable 30, the user's manual pressing operation is eliminated, which can effectively improve the convenience of automatic winding of the data cable 30.

[0038] Furthermore, considering that the driving structure 22 is a structural component that drives the winding frame 21 to rotate relative to the base 10 to achieve the winding of the data cable 30, the specific forms of the driving structure 22 can be, but are not limited to, the following embodiments.

[0039] As shown in Figures 3-7, in the first embodiment, the base 10 has a first supporting 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 of the base 10 where the first supporting surface 11 is located and is connected to the rotating shaft 211. The surface of the bracket 212 facing the first supporting surface 11 is provided with an annular guide groove 21211, which includes a locking groove 21212; the data cable 30 is wound around the rotating shaft 211 and rests on the side of the bracket 212 facing away from the first supporting surface 11. The driving structure 22 includes a locking member 221 and a coil spring 222. The release control assembly 50 drives the locking member 221 to rotate out of the locking groove 21212 according to a control signal, and the rotating shaft 211 rotates under the elastic restoring force of the coil spring 222, thereby achieving automatic reeling of the data cable 30.

[0040] The first bearing surface 11 can be a flat surface, a curved surface, or a combination of a flat surface and a curved surface. The rotating shaft 211 can be connected to the base 10 via, but is not limited to, a bearing. The bracket 212 can be detachably or non-detachably connected to the rotating shaft 211. For example, when the bracket 212 is detachably connected to the rotating shaft 211, the bracket 212 can be connected to the rotating shaft 211 via, but is not limited to, one or more of screwing, snapping, or plugging. When the bracket 212 is non-detachably connected to the rotating shaft 211, the bracket 212 can be formed into an integral structure with the rotating shaft 211 via, but is not limited to, injection molding or 3D printing, or connected to the rotating shaft 211 via bonding. The specific trajectory shape of the annular guide groove 21211 is not limited here, and designers can reasonably design it according to actual needs. The card point groove 21212 is the groove section in the annular guide groove 21211 that enables the relative 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 positions 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 introduced in detail below.

[0041] 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 where the second bearing surface 12 of the base 10 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.

[0042] The locking member 221 can be connected to the base 10 via a bearing, or via another rotating shaft 211, or via 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 designers can make reasonable designs based on 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, snapping, or plugging, and the fixed end 2222 of the coil spring can be connected to the base 10 by, but not limited to, bonding, snapping, 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.

[0043] It should be noted that when the data cable 30 is in its initial, unextended state, the portion of the locking member 221 embedded in the annular guide groove 21211 (e.g., the locking protrusion 2212 described below) is located at the location of the locking point groove 21212 of the annular guide groove 21211. At this time, the bracket 212 and the base 10 are 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 drives the rotating shaft 211 and the bracket 212 to rotate synchronously. The synchronous rotation of the rotating shaft 211 and the bracket 212 drives the portion of the locking member 221 embedded in the annular guide groove 21211 to disengage the locking point groove 21212, causing the locking member 221 to swing. The swinging of the locking member 221 causes the portion of the locking member 221 embedded in the annular guide groove 21211 to perform a cyclic motion within 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 after being pulled out can be achieved.

[0044] The release control assembly 50 drives the locking member 221 to rotate to the locking groove 21212, disengaging from the annular guide groove 21211, according to the control signal. The rotating shaft 211 rotates under the elastic restoring force of the coil spring 222. The rotation of the rotating shaft 211 drives the bracket 212 connected thereto to rotate synchronously. The rotating shaft 211 and the bracket 212 rotate synchronously, thereby achieving automatic retraction of the data cable 30. It should be noted that at this time, the locking member 221, under the action of the release control assembly 50, can cause the portion embedded in the annular guide groove 21211 to disengage from the locking groove 21212. The locking member 221 swings under the elastic restoring force of the coil spring 222 in the axial direction of the rotating shaft 211. The swinging of the locking member 221 causes the portion embedded in the annular guide groove 21211 to oscillate periodically within the annular guide groove 21211, thereby achieving automatic retraction of the data cable 30. When the data cable 30 is completely reeled in, 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 reeling can be achieved, and the data cable 30 is in the above-mentioned initial state again.

[0045] By designing the locking member 221 and the winding spring 222, the release control component 50 generates a control signal when it obtains 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 performs 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 user's manual pressing operation is eliminated, which can effectively improve the convenience of automatic winding of the data cable 30. By designing the coil spring 222, when the release 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 can be fully utilized to effectively reduce the volume of the base 10 and the bracket 212, thereby reducing the overall volume of the data cable device 1.

[0046] 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 determined 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.

[0047] Furthermore, as shown in Figures 3-7 , when the drive structure 22 includes a locking member 221 and a coiling spring 222 , the release control assembly 50 is capable of detecting the connection status of the data cable interface 31 and, based on the connection status of the data cable interface 31 , determining whether to drive the locking member 221 to rotate, thereby automatically retracting the data cable 30 . To enable the release control assembly 50 to function appropriately, in some embodiments, the release control assembly 50 includes a controller (not shown) and a release member 51 . The controller is electrically connected to the data cable 30 and configured to detect the connection status of the data cable interface 31 . The release member 51 is connected to the base 10 and electrically connected to the controller. Upon detecting that the data cable interface 31 is not connected to an external device, the controller generates a control signal and, based on the control signal, controls the release member 51 to drive the locking member 221 to rotate to disengage the locking groove 21 212 . The release member 51 serves as the power source for driving the locking member 221 . The specific embodiment of the release member 51 will be described 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 will generate a control signal when it obtains that the interface 31 of the data cable is not connected to an external device; by designing a release member 51, 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 the card point groove 21212 according to the control signal, so as to realize automatic winding of the data cable 30.

[0048] 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 also delays for a period of time before generating the above-mentioned control signal when it is obtained that the data line interface 31 is not connected to the external device. In an embodiment of the present application, the controller includes a first controller (not shown) and a second controller (not shown). The first controller is electrically connected to the data line 30 and is used to obtain the connection status of the data line interface 31. The second controller is electrically connected to the first controller and the locking member 51. The second controller starts timing when the first controller obtains that the data line interface 31 is not connected to an external device. The second controller generates a control signal when the timing time exceeds a preset time. The second controller controls the locking member 51 according to the control signal to drive the locking member 221 to rotate to disengage the locking point groove 21212. The first controller can be a PD chip, which has a register integrated therein that can obtain the connection status of the data line interface 31. The second controller can be an MCU (Microcontroller Unit) or a PLC (Programmable Logic Controller), which has a timer integrated therein that has a timing function. The specific value of the "preset time" is not limited here, and designers can reasonably design it according to actual needs. For example, the preset time can be, but is 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 also 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, so as to realize automatic winding of the data cable 30.

[0049] It should be noted that after the data cable interface 31 is disconnected from the external device, the first controller immediately begins to obtain the connection status of the data cable interface 31. If the data cable interface 31 is reconnected to the external device during a period less than the preset time, the second controller's timer will be reset to zero; the second controller will restart the timer from zero until the data cable interface 31 is again disconnected from the external device. If the timer exceeds the preset time, the controller controls the release member 51 according to the control signal to drive the locking member 221 to rotate to the disengagement point groove 21212. The data cable 30 automatically rewinds under the elastic restoring force of the coil spring 222. When the data cable 30 is completely rewound and returns to the initial state, the second controller may generate a determination signal based on which the second controller determines that the data cable interface 31 is suspended in the initial state. As shown in Figure 8, Figure 8 is a schematic diagram of the automatic rewinding process of the data cable 30 with a preset time of 30 minutes. The control logic of the automatic rewinding of the data cable 30 will not be described in detail here.

[0050] 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.

[0051] Furthermore, 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.

[0052] As shown in Figures 6 and 7, in a first embodiment, the release member 51 is adapted to generate magnetism upon power-up, and the locking member 221 is magnetic. When the timer timed by the second controller exceeds a preset time, the second controller causes the release member 51 to be powered on according to a control signal, and the locking member 221 rotates to disengage the locking point slot 21212 under the action of the magnetic attraction of the release member 51. The locking member 221 may be a permanent magnet or, like the release member 51, an electromagnet that generates magnetism upon power-up. When the locking member 221 is an electromagnet, the second controller may also cause the locking member 221 to be powered on according to a 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 member 221 rotates to fit into the releasing member 51 under the action of the magnetic attraction force of the releasing member 51, the releasing member 51 will be immediately powered off, and the locking member 221 will no longer be affected by the magnetic attraction force of the releasing member 51, so that the part of the locking member 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.

[0053] In the second embodiment, the unlocking member 51 is a motor (not shown in the figure). At this time, 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 the card point slot 21212 under the action of the driving force of the motor.

[0054] Furthermore, as shown in FIG9-FIG10 , the specific arrangement of the locking member 221 on the base 10 and the specific arrangement of the releasing member 51 on the base 10 may be, but not limited to, one or more of the following embodiments.

[0055] In the first embodiment, the first bearing surface 11 of the base 10 is provided with a limiting groove 13.
