Background Art

[0002] With the advancement of vehicle intelligence, in order to improve the riding experience and enhance the entertainment of passengers during the ride, corresponding display screens will be installed on the vehicle. However, most of the existing display screens are fixed to the armrest end of the vehicle, making the display screens not movable. When passengers need to use the display screens, they need to lean forward to operate the display screens; in addition, when the screen reflects light and cannot clearly display the screen content, passengers also need to move their own viewing angles accordingly to be able to see the interface content displayed on the screen, which makes the passengers' experience of using the screens poor and the comfort level low. Utility Model Content

[0003] In view of this, the present application provides a winding module, a winding assembly, a vehicle and a mobile terminal, wherein the winding module is applied to the winding assembly, the vehicle applies the winding assembly, the mobile terminal can be adapted to be connected to the winding assembly, and the wiring harness of the winding assembly can be stretched so that the mobile terminal connected to the wiring harness can be moved in position by adjusting the length of the wiring harness, thereby solving the above-mentioned technical problems.

[0004] The first aspect of an embodiment of the present application provides a winding module for retracting and releasing a wire harness, which includes a first shell, a second shell, a winder and a sliding bracket, wherein a connecting shaft and a first slide groove are provided on the surface of the first shell, wherein the connecting shaft is protruding from the surface of the first shell and is located in the first slide groove; the second shell is connected to the first shell to define a placement cavity together with the first shell, and the first shell and / or the second shell are provided with a wire outlet, wherein the placement cavity is connected to the outside world through the wire outlet; the connecting shaft and the first slide groove are located in the placement cavity; the winder is installed in the placement cavity cavity, and is rotatably connected with the connecting shaft, a second slide groove is formed on one side of the winder, and an annular slide and a locking portion arranged adjacent to the annular slide groove are arranged in the second slide groove; the wire harness is wound around the outer periphery of the winder, and both ends of the wire harness are penetrated with wire outlets to move from the placement cavity to the outside of the placement cavity; the sliding bracket is penetrated by the connecting shaft and slidably arranged in the first slide groove, and a convex column is arranged on the surface of the sliding bracket, and the convex column is inserted into the second slide groove; when the wire harness is retracted and released, the winder rotates and the convex column slides in the annular slide groove, and when the wire harness is stopped, the convex column is clamped in the locking portion to stop the winder from rotating.

[0005] In the present application, as the winder in the winding module rotates, the state of the wire harness wound on the winder changes, thereby, the length of the wire harness that can extend out of the placement cavity changes accordingly; when the user uses the winding module, the wire harness can be pulled to lengthen the length of the wire harness outside the placement cavity. At this time, the winder rotates along a first rotation direction, and the sliding bracket moves along the groove body direction of the first slide groove, and moves along the annular slide in the second slide groove, forming an arc motion relative to the rotating winder; when the user no longer pulls the wire harness, that is, the wire harness is no longer subjected to the pulling force applied by the user, at this time, a reverse rotation force can be applied to the winder to rotate the wire harness in a second rotation direction opposite to the first rotation direction, thereby The pulled-out part of the wiring harness is recovered as the winder rotates in the opposite direction. When the boss of the sliding bracket moves accordingly and is stuck in the locking part, the winder is in a locked state. At this time, the winder cannot continue to rotate, and the length of the wiring harness located outside the accommodating cavity can be fixed. Thus, the length of the wiring harness located outside the placement cavity is fixed. In this way, the mobile terminal using the winding module can move freely within the movable range formed by the wiring harness, thereby enhancing the comfort of passengers using the mobile terminal. When the user wants to completely recover the wiring harness, he can pull a smaller length of the wiring harness to make the boss leave the locking part and enter the changing slide. At this time, rotate the winder again, and the wiring harness can rotate with the winder, so that most of the wiring harness can be received in the placement cavity.

[0047] Please continue to refer to Figures 1 to 9Specifically, the winding module 1 includes a first shell 11, a second shell 12, a winding machine 15 and a sliding bracket 17, wherein a connecting shaft 111 and a first slide groove 112 are provided on the surface of the first shell 11, wherein the connecting shaft 111 is protruding from the surface of the first shell 11, and the connecting shaft 111 is located in the first slide groove 112; the second shell 12 is connected to the first shell 11 to define a placement cavity 13 together with the first shell 11, and the first shell 11 and / or the second shell 12 are provided with a wire outlet, wherein the placement cavity 13 is connected to the outside through the wire outlet, and the connecting shaft 111 and the first slide groove 112 are located in the placement cavity 13; the winding machine 15 is installed in the placement cavity 13, and is rotatably connected to the connecting shaft 111, and one side of the winding machine 15 forms There is a second slide groove 151, in which an annular slide 1511 and a locking portion 15411 arranged adjacent to the annular slide 1511 are arranged. The wiring harness 16 is wound around the outer periphery of the winder 15, and both ends of the wiring harness 16 are provided with wire outlets, and have been moved from the placement cavity 13 to the outside of the placement cavity 13; and a sliding bracket 17 is passed through the connecting shaft 111 and slidably arranged in the first slide groove 112, and a boss 171 is provided at one end of the sliding bracket 17 away from the connecting shaft 111, and the boss 171 is inserted into the second slide groove 151; when the wiring harness 16 is retracted or released, the winder 15 rotates and the boss 171 slides in the annular slide 1511, and when the wiring harness 16 stops being retracted or released, the boss 171 is engaged with the locking portion 15411 to cause the winder 15 to stop rotating.

[0048] The winding module 1 may have one outlet, or may have Figure 1 The multiple outlets spaced apart from each other shown in the embodiment can be separated into Figure 1 The two wire outlets in the embodiment are named as the first wire outlet 14 and the second wire outlet 122, respectively, and the two ends of the wiring harness are named as the first connection end 1611 and the second connection end 1621; the wire outlet can be directly opened on the first shell 11 and / or the second shell 12 (such as the second wire outlet 122), and can also be formed by providing corresponding docking recesses on the first shell 11 and / or the second shell 12 (such as the first wire outlet 14), as shown in the embodiment of the figure, wherein the first shell 11 is provided with a first recess 113, and the second shell 12 is correspondingly provided with a second recess 121, so that when the two shells are connected, the first recess 113 and the second recess 121 are connected to form the first wire outlet 14.

[0049] It should also be noted that the annular slide 1511 can be a circular slide or a polygonal slide. The shape of the slide is not limited in the present application. As long as the slide is arranged around a point outside a certain slide track, it can be considered as an annular slide. The first shell and the second shell can be connected by various connection methods such as screw connection, bonding, snap connection, and cover connection.

[0050] First, the winding module 1 in the above embodiment is described in combination with the usage status of the winding module 1. It should be explained in advance that, of the first connection end 1611 and the second connection end 1621 of the wiring harness 16, one is used to connect the power supply required to be connected to the mobile terminal 2, and the other is used to connect the mobile terminal 2, that is, the mobile terminal 2 is connected to the power supply through the wiring harness 16, wherein the power supply is generally not movable, so in the subsequent description process, the power supply is regarded as a non-movable component, that is, the power supply is in a fixed position.

[0051] In this embodiment, when the user retracts or releases the wiring harness 16, the user can pull the first connection end 1611 and / or the second connection end 1621 located outside the placement cavity 13 to rotate the cable winder 15, so that the boss 171 moves along the annular slide 1511, the boss 171 makes an arc motion relative to the winding module 1, and the sliding bracket 17 moves in the sliding direction D2 and / or the offset direction D1 of the first slide groove 112 due to the movement of the boss 171; when the user stops retracting or releasing the wiring harness 16, if the boss 171 moves and is engaged with the locking portion, the cable winder 15 is locked due to the mutual abutment between the locking portion and the boss 171. At this time, the wiring harness 16 is locked together with the cable winder 15, so that the wiring harness 16 is not extended outside the placement cavity 13. The degree is fixed, and the distance between the first connection end 1611 and the second connection end 1621 of the wiring harness 16 located outside the placement cavity 13 is fixed, so that the moving range of the mobile terminal 2 connected to the first connection end 1611 or the second connection end 1621 relative to the power source is fixed, so that the mobile terminal 2 can move freely within this range; in addition, if the user needs to recycle the wiring harness 16, the wiring harness 16 can be pulled a short distance to rotate the cable winder 15 relative to the boss 171, and the boss 171 leaves the locking portion 15411 and enters the annular slide 1511, so that the resistance formed between the cable winder 15 and the boss 171 disappears, and the cable winder 15 can continue to rotate until the required wiring harness 16 is completely recovered into the placement cavity 13.

[0052] Among them, compared with the above embodiments, it should be supplemented that, when assembling the winding module 1, a certain length of the wire harness 16 can be reserved outside the placement cavity 13, so that there is a certain distance between the first connection end 1611, the second connection end 1621 of the wire harness 16 and the first shell 11, the second shell 12, so as to reduce the structural mutual interference when the winding module 1 is connected with the power supply and the mobile terminal 2. At the same time, it can also facilitate the user to take the wire harness 16 to a certain extent; in the placement cavity 13, there is a local fixation between the wire harness 16 and the winder 15, so that when the user pulls the wire harness 16, the winder 15 can be driven by the wire harness 16 and rotate synchronously.

[0053] In summary, in the present application, by improving the winding module 1, the mobile terminal 2 in the vehicle cabin can have a larger moving range, so that the user can move the mobile terminal 2 accordingly according to his or her own needs, so that the user can lean on the vehicle seat to use the mobile terminal 2, changing the previous usage state in which the mobile terminal 2 is stationary and the user is moving to the usage state in which the mobile terminal 2 is moving and the user can be stationary, so that the user can use the mobile terminal 2 more comfortably; and when the user does not need to continue to use the mobile terminal 2, the wiring harness 16 pulled out of the placement cavity 13 can also be recovered into the placement cavity 13 to complete the storage of the wiring harness 16, so that the wiring harness 16 will not be placed in a messy manner in the vehicle cabin, thereby enhancing the cleanliness of the interior of the vehicle cabin.

[0054] It should be additionally explained that, in the above-mentioned embodiment, the first shell portion 11 and the second shell portion 12 can be two actually separated parts, or two virtually separated parts (that is, the first shell portion 11 and the second shell portion 12 are integrally formed). Specifically, when the first shell portion 11 is independent of the second shell portion 12, the covering connection between the two expresses the covering action when the two are connected, and also expresses the relative positional relationship between the two to a certain extent (the two are in a stacked position in space, and the connection edges coincide); when the first shell portion 11 and the second shell portion 12 are integrally formed, it can be understood that when the winding module has only one shell portion, the shell portion is virtually divided into the first shell portion 11 and the second shell portion 12, and no additional connection operation is required between the first shell portion 11 and the second shell portion 12. At this time, the covering connection between the two emphasizes the positional state of the two being stacked in space.

[0055] Please refer to further Fig. 9 In some embodiments, the annular slide 1511 includes an inner ring slide 15111, an outer ring slide 15112 and a connecting channel 15113. The inner ring slide 15111 and the outer ring slide 15112 are connected through the connecting channel 15113. The locking portion 15411 is arranged on the connecting channel 15113 of the inner ring slide 15111 and the outer ring slide 15112. The sliding bracket 17 slides in the first slide and can change the sliding radius of the boss 171 relative to the center of the second slide groove 151, so as to switch the boss 171 from the inner ring slide 15111 to the outer ring slide 15112 or from the outer ring slide 15112 to the inner ring slide 15111.

[0056] In order to more clearly reflect the features of the above embodiments, Figure 6 and Fig. 9 , to Figure 1-Figure 10 The winding module 1 shown is provided for exemplary purposes only.

[0057] Depend on Fig. 9It can be seen that the outer wall of the outer ring slideway 15112 overlaps with the side wall of the second slideway 151, that is, the locking portion 15411 is spaced from the side wall of the second slideway 151. If the initial position of the boss 171 is located at the inner ring slideway 15111, when the user pulls the first connection end 1611 and / or the second connection end 1621 of the wire harness 16, as the wire harness 16 moves, the cable winder 15 rotates along the wire pulling rotation direction D4 in the figure. Relatively speaking, because the boss 171 moves along the direction of the inner ring slideway 15111 and the outer ring slideway 15112, and the sliding bracket 17 is limited by the side wall of the first slideway 112, the boss 171 on the sliding bracket 17 moves relative to the cable winder 15 along the wire winding rotation direction D3 shown in the figure. During the rotation of the winder 15, when the sliding bracket 17 slides along the inner ring slideway 15111, the sliding radius of the boss 171 relative to the center of the second slideway 151 will change. At this time, the boss 171 makes an eccentric movement in the second slideway 151. The boss 171 is subjected to different support forces from the two side walls of the slideway at different positions of the inner ring slideway 15111. When the boss 171 moves to a position close to the connecting channel 15113, the boss 171 is only subjected to the support forces from the inner ring slideway 15111 close to the second slideway 15113. 1, and the supporting force of the inner ring slideway 15111 away from the central side wall of the second slide groove 151 disappears due to the setting of the connecting channel 15113, so the boss 171 will switch from the inner ring slideway 15111 to move to the outer ring slideway 15112 along the connecting channel 15113, or move to the locking portion 15411 to lock the winding module 1; when the user recycles the wire harness 16, the boss 171 moves from the outer ring slideway 15112 to the inner ring slideway 15111 via the connecting channel 15113;

[0058] By the same token, if the initial position of the boss 171 is located at the outer ring slide 15112, when the user pulls the first connection end 1611 and / or the second connection end 1621 of the wiring harness 16, as the wiring harness 16 moves, the cable winder 15 rotates along the wire pulling rotation direction D4 in the figure. Relatively speaking, because the boss 171 moves along the direction of the inner ring slide 15111 and the outer ring slide 15112, and the sliding bracket 17 is limited by the side wall of the first slide groove 112, the boss 171 on the sliding bracket 17 moves relative to the cable winder 15 along the wire winding rotation direction D3 shown in the figure. During the rotation of the winder 15, when the boss 171 moves to the position of the connecting channel 15113, the boss 171 is only supported by the outer ring slide 15112 away from the central side wall of the second slide groove 151, and the supporting force of the outer ring slide 15112 close to the central side wall of the second slide groove 151 disappears due to the setting of the connecting channel 15113. Therefore, the boss 171 will switch from the outer ring slide 15112 to the inner ring slide 15111, or move to the locking portion 15411 along the connecting channel 15113 to lock the winding module 1; when the user recycles the wiring harness 16, the boss 171 moves from the inner ring slide 15111 to the outer ring slide 15112 via the connecting channel 15113.

[0059] In summary, two annular slides 1511, an inner ring slide 15111 and an outer ring slide 15112 are provided in the above embodiment, and the two slides can be connected through the connecting channel 15113. In this way, when the winding module 1 is switched from the locked state to the active state, the boss 171 can be moved to the inner ring slide 15111 or the outer ring slide 15112 accordingly to recover the wiring harness 16 or pull out the wiring harness 16. In this way, in the process of the boss 171 leaving the locking portion 15411 and moving to any annular slide 1511, because the locking portion 15411 is separated from the side wall of the second slide groove 151, the locking portion 15411 will not form a limiting recess that hinders the sliding of the locking portion 15411 due to the side wall adjacent to the second slide groove 151, so that the boss 171 is stuck in the locking portion 15411, thereby reducing the situation where the winding module 1 cannot operate normally due to the boss 171.

[0060] Please continue to refer to Fig. 9Further, in some embodiments, a central convex portion 153, a first arc-shaped convex portion 154, and a second arc-shaped convex portion 155 are formed on one side surface of the winding device 15, and a plug-in through hole 1531 for inserting the connecting shaft 111 is also provided on the central convex portion 153, an inner ring slideway 15111 is defined between the first arc-shaped convex portion 154 and the central convex portion 153, an outer ring slideway 15112 is defined between the second arc-shaped convex portion 155 and the first arc-shaped convex portion 154, and a locking portion 15411 and a connecting channel 15112 are defined between the locking portion 15411 and the connecting channel 15112. 5113 is arranged on the first arc-shaped protrusion 154, so that the side walls of the central protrusion 153, the first arc-shaped protrusion 154 and the second arc-shaped protrusion 155 become the side walls of the inner ring slide 15111 and the outer ring slide 15112 respectively. When manufacturing the winder 15, the winder 15 can be directly manufactured by setting a corresponding mold for injection molding and pressing, without the need to additionally open the annular slide 1511, the connecting channel 15113 and the second slide groove 151 on the surface of the winder 15, thereby improving the production efficiency of the winder 15.

[0061] Furthermore, in some embodiments, the locking portion 15411 is formed by a recessed end portion of the first arc-shaped protrusion 154, and the two side walls of the locking portion 15411 are arranged at an angle, so that when the user pulls the wiring harness 16 to drive the cable winder 15 to rotate and makes the boss 171 leave the locking portion 15411, the two side walls of the locking portion 15411 can guide the boss 171 to enter the corresponding annular slide 1511; when the boss 171 moves to the locking portion 15411, the two side walls can jointly limit the boss 171 so that the boss 171 is stuck in the locking portion 15411.

[0062] Please refer to Figure 3 and Figure 6 In some embodiments, the sliding bracket 17 is provided with a guide hole 172, and the connecting shaft 111 is provided with the guide hole 172 to connect the sliding bracket 17, wherein the diameter of the guide hole 172 is larger than the diameter of the connecting shaft 111, so that under the joint action of the first slide groove 112 and the connecting shaft 111, the sliding bracket 17 can be moved along Figure 6 The sliding direction D2 moves in the Figure 6 In the offset direction D1, the outer side of the sliding bracket 17 is limited by the side wall of the first slide groove 112, and the inner side is guided by the connecting shaft 111, thereby limiting the movement of the sliding bracket 17 in the offset direction D1. When the boss 171 slides on any annular slide 1511, the friction between the boss 171 and the side wall of the annular slide 1511 will not increase due to the offset of the sliding bracket 17. As mentioned above, the rotation of the winder 15 will not be affected by the friction formed between the boss 171, thereby ensuring the smoothness of the rotation of the winder 15 in the winding module 1 to a certain extent.

[0063] Furthermore, in some embodiments, in the offset direction D1 of the sliding bracket 17, the size of the sliding bracket 17 is adapted to the size of the groove body of the first slide groove 112, so that the sliding bracket 17 is difficult to move relative to the first shell 11 in the offset direction D1. At this time, the annular slide 1511 on the winder 15 can be correspondingly arranged to enable the boss 171 to move relative to the annular slide 1511.

[0064] In some embodiments, the first arc-shaped protrusion 154 includes a first protrusion 1541 and a second protrusion 1542 spaced apart from each other, the first protrusion 1541 and the second protrusion 1542 are sequentially connected end to end, and the locking portion 15411 is formed at the head of the first protrusion 1541; the connecting channel 15113 also includes a first connecting channel 15113a and a second connecting channel 15113b, and the tail of the second protrusion 1542 is adjacent to the outer ring slideway 15112 and is formed with a guide inclined surface 15421 to jointly limit the first connecting channel 15113a with the locking portion 15411; the first protrusion 1541 A first transition slope 15412 is formed at the tail of 541 near the outer ring slide 15112, and a second transition slope 15422 is formed at the head of the second protrusion 1542 near the inner ring slide 15111. Along the arc direction of the first arc-shaped protrusion 154, the first transition slope 15412 and the second transition slope 15422 are staggered to limit the second connecting channel 15113b, wherein the first transition slope 15412, the second transition slope 15422 and the guide slope 15421 are used to guide the movement of the boss 171 so that the boss 171 moves to the corresponding slide.

[0065] Furthermore, a stop protrusion 156 is provided on the side of the outer ring slide 15112 away from the inner ring slide 15111 and adjacent to the second connecting channel 15113b. The stop protrusion 156 is used to push the boss 171 into the second connecting channel 15113b through a reaction force. In this way, when the boss 171 moves to the stop protrusion 156, the stop protrusion 156 can help the boss 171 enter the inner ring slide 15111 via the second connecting channel 15113b.

[0066] For reference Figure 3 and Figure 7 In some embodiments, a mounting groove 157 is recessed on the first surface of the winder 15 away from the first shell portion 11, and a through hole 1571 is opened at the bottom of the mounting groove 157 for rotatably connecting the connecting shaft 111; the winding module 1 also includes a coil spring 18, the inner end of the coil spring 18 is fixed to the connecting shaft 111, and the outer periphery of the coil spring 18 is fixed to the side wall of the mounting groove 157. The coil spring 18 is used to drive the winder 15 to rotate to control the winding state of the wire harness 16 on the winder 15, so that the winding module 1 has an automatic winding function.

[0067] In addition, during the automatic winding process of the winding module 1, due to the restrictions of the first arc-shaped protrusion 154, the second arc-shaped protrusion 155 and the central protrusion 153, the boss 171 can slide along the annular slide 1511. During the sliding process of the boss 171, due to the guidance of the first transition slope 15412, the second transition slope 15422 and the guide slope 15421, the boss 171 can smoothly switch the annular slide 1511, so that the boss 171 and the various protrusions and the groove wall of the second slide groove 151 will not collide and produce noise. In this way, the noise during the operation of the winding module 1 can be reduced, and at the same time, the smooth rotation of the winder 15 can be ensured, making the winding module 1 more in line with user needs.

[0068] Specifically, please refer to Figure 3 and Figure 7 When the cable winder 15 rotates along the cable pulling rotation direction D4, the coil spring 18 is fixed to the connecting shaft 111 (which can be inserted into the connecting socket 1111 preset on the connecting shaft 111) at its inner end and fixed to the groove side wall of the mounting groove 157 at its outer periphery. Therefore, the outer periphery of the coil spring 18 rotates with the cable winder 15 and the inner end is fixed relative to the connecting shaft 111 to produce elastic deformation. Thus, the coil spring 18 forms elastic potential energy. When the block is located at the locking portion 15411, the coil spring 18 can apply force to the cable winder 15 to make the cable winder rotate. 15 has a tendency to rotate along the winding rotation direction D3, and the card block is stably stuck in the locking portion 15411 due to the interaction with the locking portion 15411, the connecting shaft 111 and the first slide groove 112; if the card block leaves the locking portion 15411 and enters the annular slide 1511, and no longer pulls the wire harness 16, the coil spring 18 will release its elastic potential energy accumulated due to elastic deformation, so that the winder 15 rotates along the winding rotation direction D3, thereby realizing the automatic winding function of the winding module 1.

[0069] For easier understanding, please refer to Fig. 9 , and combined with reference Figure 9a-9h , the above embodiment is described in detail, wherein only the boss 171 is marked in the figure, and because the movement of the sliding bracket 17 is synchronized with the boss 171, the position of the boss 171 in the figure on the winder 15 can represent the position of the sliding bracket 17 on the winder 15.

[0070] Figure 9a-9hThe diagram exemplarily shows the position of the boss 171 in the annular slide 1511 relative to the winding module 1 when the winding module 1 rotates, wherein it should be noted that it is the winder 15 that actually rotates, not the boss 171; the possible stress states of the winder 15 at that moment are exemplarily marked on the right side of the drawing (it should be noted that due to the relative positional relationship between the boss 171 and the annular slide 1511, the boss 171 may interact with both side walls, or may only interact with one side wall, and the interaction with the side wall of the slide may be zero, which needs to be confirmed in combination with the actual wire pulling situation. Since it does not affect the features in this embodiment, it is not described in detail in this application), wherein ① in the force analysis diagram of the winder 15 in each drawing corresponds to the stress state of the winder 15 when the user pulls out the wire harness 16, and ② in the diagram corresponds to the stress state of the winder 15 when the user retracts the wire harness 16, and the force analysis point of the winder 15 is the point corresponding to the geometric center of the boss 171.

[0071] First of all, it should be noted that Figure 9a-9h In the illustrated embodiment, the boss 171 is initially located at the inner ring slide 15111, that is, when the user pulls out the wire harness 16, the boss 171 is moved from the inner ring slide 15111 via the first connecting channel 15113a to the locking portion 15411 and the outer ring slide 15112 accordingly; when the user retracts the wire harness 16, the boss 171 is moved from the outer ring slide 15112 via the second connecting channel 15113b to the inner ring slide 15111, according to Figure 9a to Figure 9h The sequence gradually shows that when the user pulls out the wire harness 16, locks the wire harness 16, and then retracts the wire harness 16, the boss 171 moves from the inner ring to the locking portion 15411, then moves from the locking portion 15411 to the outer ring slide 15112, and then moves from the outer ring slide 15112 to the inner ring slide 15111.

[0072] When the boss 171 is located at Figure 9a When the cable is in the position shown, if the user pulls the wire harness 16, the cable winder 15 will be pulled by the wire harness 16 and rotate along the wire pulling rotation direction D4, thereby driving the coil spring 18 to deform. Accordingly, since the boss 171 is limited by the first slide groove 112 and the connecting shaft 111, a relative force may be formed between the boss 171 and the side wall of the inner ring slideway 15111, so that the cable winder 15 is correspondingly subjected to the force of the boss 171 (refer to F in the figure). a3 and Fa4, where F a3 and F a4 At this time, the winding device 15 is subjected to the pulling force of the wire harness 16 in the tangential direction (refer to F in the figure). a2 ), and is also subjected to the tension of the coil spring 18 (see F in the figure). a1, it should be noted that when the harness 16 is first pulled, F a1 =0; as the harness 16 is continuously pulled, the deformation of the coil spring 18 increases, F a1 The value of increases accordingly). In this process, because the pulling force applied by the user to the harness 16 is sufficient to overcome the elastic potential energy of the deformation of the coil spring 18, the pulling force F of the harness 16 on the winding device 15 is a2 Greater than the tension F of the coil spring 18 a1 At this time, the winding module 1 rotates along the wire pulling rotation direction D4, and the protruding column 171 rotates along the wire taking-up rotation direction D3 relative to the winding device 15;

[0073] Then, the boss 171 moves relative to the winding device 15 to Figure 9b At this time, the boss 171 interacts with the side wall of the inner ring slideway 15111, and the boss 171 acts on the winder 15 to form a force F b3 and F b4 (Among them, F b3 and F b4 At this time, the winding device 15 is also subjected to the pulling force F of the wire harness 16. b2 , and the tension F of the coil spring 18 b1 , because F b2 Greater than F b1 , thus, the wire winder 15 continues to rotate along the wire pulling rotation direction D4;

[0074] Then, the boss 171 moves relative to the winding device 15 to Fig.9c At this time, the boss 171 is located in the first communication channel 15113a and is about to move to the locking portion 15411. At this time, there is no interaction between the boss 171 and the inner ring slideway 15111 and the outer ring slideway 15112. Therefore, the winding device 15 is only subjected to the pulling force F of the wire harness 16. c2 At this time, the winding device 15 has a pulling force F on the wiring harness 16. c2 Under the action of the spring 18, the tension F c1 Continue to move so that the boss 171 can enter the outer ring slideway 15112 under the guidance of the guide slope 15421;

[0075] When the protrusion 171 enters the first communication channel 15113a, if the user no longer pulls the wire harness 16, the wire winder 15 loses the pulling force F of the wire harness 16. c2 At this time, the winding device 15 is only subjected to the tension of the coil spring 18. c1At this time, the cable winder 15 rotates along the cable winding rotation direction D3, and moves under the guidance of the guide slope 15421 and is clamped on the locking portion 15411. At this time, the boss 171 is stationary relative to the cable winder 15. The relative position of the boss 171 relative to the cable winder 15 is as shown in FIG. Figure 9d As shown, where F d3 、F d4 It is used to indicate the supporting effect of the side wall of the locking portion 15411 on the block, F d1 F represents the pulling force of the coil spring 18 on the winding device 15. d2 Indicates the pulling force of the wire harness 16 on the winding device 15. If the user continues to pull the wire harness 16, that is, F d2 >F d1 The wire winder 15 can rotate along the wire pulling rotation direction D4 in the figure. When passing through the guide inclined surface 15421, due to the guiding effect of the guide inclined surface 15421, the block enters the outer ring slideway 15112;

[0076] At this time, the block is in the position on the winding device 15. Fig.9e The wire harness 16 is pulled continuously. At this time, for the winding device 15, the wire harness 16 pulling force F e2 Greater than the spring tension F 18 e1 It should also be noted that the winding device 15 is also subjected to a force F formed between the protruding column 171 and the guiding inclined surface 15421. e3 , and the force F between the protrusion 171 and the side wall of the second slide groove 151 e4 (Among them, F e3 、F e4 The direction of the combined force on the winding machine 15 causes the winding machine 15 to continue to rotate along the wire pulling rotation direction D4, so that the block moves relative to the winding machine 15 to Figure 9f The location shown;

[0077] At Figure 9f In the process, the winding device 15 will be subjected to the pulling force F of the wire harness 16 f2 , the force F between the boss 171 and the stop convex portion 156 f3 and the tension F of the coil spring 18 f1 , wherein the stop convex portion 156 can react on the boss 171 to move the boss 171 relative to the winder 15 to the second transition slope 15422, that is, Figure 9g As shown in FIG. 1 , the boss 171 and the second transition slope 15422 form a F g3 At this time, the winding device 15 is also subjected to the pulling force F of the wire harness 16. g2 And coil spring 18 tension F g1 , and F g2 >F g1In this way, the winding device 15 continues to rotate along the wire pulling rotation direction D4 under the combined force of the three forces, so that the block moves to Figure 9h The location shown;

[0078] At Figure 9h In the embodiment, the block may be in contact with the first transition slope 15412, and thus move to the inner ring slideway 15111 under the guidance of the first transition slope 15412. When the block acts on the first transition slope 15412, the winding device 15 is subjected to the pulling force F of the wire harness 16. h2 , coil spring 18 tension F h1 And the force F between the block and the first transition slope 15412 h3 (where F h3 can be 0), and because F h2 Greater than F h1 , so the wire winder 15 can continue to rotate along the wire pulling rotation direction D4;

[0079] Please refer again to Figure 9d to Figure 9h When the winding module 1 is no longer subjected to the pulling force of the wire harness 16, its specific stress state can refer to the stress analysis diagram ② in each figure. At this time, the winding module 1 rotates along the wire-receiving rotation direction D3, so that the boss 171 rotates along the wire-pulling rotation direction D4 relative to the winding module 1. During the rotation of the winder 15, the stop protrusion 156, the guide bevel 15421, the first transition bevel 15412 and the second transition bevel 15422 can all act on the boss 171 to assist the boss 171 in replacing the annular slide 1511.

[0080] For reference Figure 1 and Fig.10 In some embodiments, the wiring harness 16 includes a fixed section 161 and a movable section 162, and the wiring harness 16 is formed with a first connection end 1611 and a second connection end 1621, the first connection end 1611 is arranged on the fixed section 161, and the second connection end 1621 is arranged on the movable section 162; the fixed section 161 is fixed to the surface of the second shell 12, and the movable section 162 is wound around the outer periphery of the winder 15, in the placement cavity 13, and the fixed section 161 is electrically connected to the movable section 162, so that the movable section 162 can realize the adjustment of the moving range of the mobile terminal 2 connected to the winding module 1, and the fixed section 161 can be stably connected to the power supply to ensure stable power supply of the wiring harness 16.

In this way, because the conductive member 19 is electrically connected to the circuit board 20, the electrical connection between the fixed section 161 and the movable section 162 is achieved.

[0082] Please continue to refer to Figure 5 In some embodiments, a conductive groove 201 is provided on the surface of the circuit board 20, and a conductive support foot 191 is provided on the conductive member 19. The conductive support foot 191 slides against the conductive groove 201, so that a stable electrical connection can be established between the conductive member 19 and the conductive groove 201, and when the cable winder 15 rotates, the conductive support foot 191 can slide along the groove body of the conductive groove 201, so that when the user uses the mobile terminal 2 and pulls the wiring harness 16, a stable electrical connection is always maintained between the fixed section 161 and the movable section 162.

[0083] Furthermore, in some embodiments, a plurality of concentrically arranged conductive grooves 201 are provided on the surface of the circuit board 20, and the conductive member 19 is provided with a plurality of conductive legs 191 of different lengths, and one conductive leg 191 slides against one conductive groove 201 correspondingly. In this way, the contact position of each conductive leg 191 with the circuit board 20 is different, thereby reducing the short circuit phenomenon caused by the collision of two conductive legs 191.

[0084] For reference Figures 1 to 7 In some embodiments, a mounting lug 123 is provided on the outer circumferential surface of the first shell portion 11 and / or the second shell portion 12, and the mounting lug 123 is used to connect the main body to be installed of the winding module 1, so that the first shell portion 11 and / or the second shell portion 12 is fixed to the main body to be installed, so as to reduce the situation where the first shell portion 11 and / or the second shell portion 12 shakes with the wiring harness 16 and bumps into people.

[0085] like Fig.10 As described above, in some embodiments, in order to protect the wiring harness 16 leaving the placement cavity 13, a bellows 3 is sleeved on the outer side of the part of the movable section 162 leaving the placement cavity 13, and the inner surface of the bellows 3 is smoothed to reduce the friction between the bellows 3 and the wiring harness 16, thereby protecting the wiring harness 16; in addition, in other embodiments, a tensile layer may be added to the outer surface of the wiring harness 16 to enhance the tensile strength of the wiring harness 16 and extend the service life of the wiring harness 16.

[0086] It should be understood that when the winding module 1 has multiple outlets, the user can determine to a certain extent which connection end of the wire harness 16 is located at the outlet, so that the user can quickly apply the correct connection end. Fig.10 In the winding assembly shown, the first connection end 1611 is used to connect to a power source, and the second connection end 1621 is used to connect to a mobile device. Due to the different positions of the first wire outlet 14 and the second wire outlet 122, and the first connection end 1611 corresponds to the first wire outlet 14, and the second connection end 1621 corresponds to the second wire outlet 122, the positions of the first wire outlet 14 and the second wire outlet 122 on the winding module 1 are different, so the user can judge the corresponding connection end of the wiring harness 16 by the position of the different wire outlets, thereby improving the convenience of the user in using the winding assembly.

[0087] In some embodiments, the wire harness 16 is a flat wire, so that the thickness of the wire harness 16 is small, thereby reducing the total volume of the winding module 1; or, a plurality of wires may be provided on the periphery of the winding device 15. Figure 8 , Fig. 9 The winding groove 152 shown is used to store the wire harness 16 inside the groove body, thereby reducing the total volume of the winding module 1.

[0088] Please refer to Figures 10 to 12 The present application also mentions a mobile terminal 2, which can be adapted to connect to the winding module 1, wherein the interface 22 of the mobile terminal 2 is provided with two locking convex parts 23, and when the second connection end 1621 is inserted into the interface 22, the wire harness 16 is locked between the two locking convex parts 23, thus enhancing the connection strength between the mobile terminal 2 and the wire harness 16, and when the mobile terminal 2 moves, the wire harness 16 will not be separated from the interface 22 of the mobile terminal 2 due to the interaction with the winding module 1. Fig.12 The internal structure diagram where the interface 22 is located is schematically marked, and two locking protrusions 23 are movably arranged in the slot 24. When the wiring harness 16 is inserted into the socket, the two locking protrusions 23 enter the slot 24 and are relatively far away from each other to clamp the wiring harness 16 in the middle, thereby increasing the connection strength between the wiring harness 16 and the mobile terminal 2; in addition, because the locking protrusions 23 are arranged inside the body 21 of the mobile terminal 2, the mobile terminal 2 does not need to provide an additional connection part capable of connecting the wiring harness 16 on the outside of the body 21, thereby reducing the total volume of the mobile terminal 2 to a certain extent.
