Description

Technical Field

[0001] The present application relates to the technical field of wire winding, and in particular to a wire winding mechanism and a charging device. Background Art

[0002] Currently, winding mechanisms such as measuring tapes use a coil spring to control the release and winding of the wire. When the wire is pulled out, the coil spring accumulates force and then releases the force to drive the wire to be wound and stored. The release of the force causes the wire to move at high speed, causing the wire to twist and hit the user's hand, and even cause hand injuries in severe cases. Summary of the invention

[0003] Some embodiments of the present application provide a winding mechanism, comprising: a shell having a accommodating cavity; a winding drum disposed in the accommodating cavity and rotatably connected to the shell; a wire wound around the circumference of the winding drum; a circuit board electrically connected to the wire; and a speed limiting component disposed on the shell and abutting against the winding drum in the thickness direction of the winding drum, wherein when the winding drum and the shell rotate relative to each other, the speed limiting component and the winding drum can move relative to each other to adjust the abutment force between the winding drum and the shell; when the winding drum rotates in a first direction relative to the shell, the speed limiting component is used to reduce the abutment force; when the winding drum rotates in a second direction relative to the shell, the speed limiting component is used to increase the abutment force, wherein the first direction is opposite to the second direction.

[0004] The beneficial effects brought by the technical solution of the present application are that in the winding mechanism of the present application, when the winding drum and the housing rotate relative to each other, the speed limiting component moves relative to the winding drum to adjust the contact force between the winding drum and the speed limiting component. The speed limiting component adjusts the contact force between the speed limiting component and the winding drum, thereby adjusting the friction force between the speed limiting component and the winding drum, and controls the rotation speed of the winding drum through friction, thereby reducing the risk of the wire being injured by the user due to being pulled by the high-speed rotation of the winding drum.

[0015] The present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be specifically noted that the following embodiments are only used to illustrate the present application, but do not limit the scope of the present application. Similarly, the following embodiments are only partial embodiments of the present application rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present application.

[0016] Referring to "embodiments" in the present application means that the specific features, structures, or characteristics described in connection with the embodiments may be included in at least one embodiment of the present application. The phrase appears in various positions in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art will explicitly and implicitly understand that the embodiments described herein may be combined with other embodiments.

[0017] The present application describes a wire winding mechanism for storing wire materials, and the wire materials can be a series of strip-shaped objects such as tape measures, data cables, ropes, etc. that can be stored in the wire winding mechanism by being wound into a roll.

[0018] Please refer to Figure 1 , Figure 1Schematic diagram of the frame of the wire winding mechanism 100 in some embodiments of the present application. The wire winding mechanism 100 may include a housing 10, a wire winding assembly 20, a wire 30, a speed limiting assembly 40, and a locking assembly 50. The housing 10 may have a receiving cavity. The wire winding assembly 20 may be disposed in the receiving cavity. The wire winding assembly 20 may be used to wind the wire 30 so that the wire 30 is wound into a roll and stored in the receiving cavity. The wire 30 may also be released from the wire winding assembly 20 and extend out of the receiving cavity so that a part of the wire 30 is located outside the housing 10 for convenient use. The speed limiting assembly 40 is disposed between the wire winding assembly 20 and the housing 10 and cooperates with the wire winding assembly 20 to control the speed of winding and / or releasing the wire 30 by the wire winding assembly 20 within a safe speed range, reducing the risk of the wire 30 causing harm to the user due to being pulled by the wire winding assembly 20 or the user. The locking assembly 50 is disposed on the housing 10 and cooperates with the wire winding assembly 20 to lock or unlock the wire winding assembly 20 so as to control the length of the part of the wire 30 outside the housing 10 at any time. Of course, the locking assembly 50 may also cooperate with the wire 30 to lock or unlock the wire 30 so as to control the length of the part of the wire 30 outside the housing 10 at any time.

[0019] In some embodiments, when the wire 30 can enter and exit the receiving cavity, the locking assembly 50 can lock the wire winding assembly 20 so that the wire winding assembly 20 no longer winds or releases the wire 30, making the length of the part of the wire 30 outside the receiving cavity constant. When the locking assembly 50 unlocks the wire winding assembly 20, the wire winding assembly 20 can be made to wind or release the wire 30 as needed to adjust the length of the part of the wire 30 outside the receiving cavity.

[0020] In some embodiments, the locking assembly 50 can lock the wire winding assembly 20 and / or the wire 30 by means of clamping and fixing. In some embodiments, the locking assembly 50 can lock the wire winding assembly 20 and / or the wire 30 by means of friction. In some embodiments, the locking assembly 50 can be a clamping mechanism, a button, or other forms of structures, and can be specifically determined according to the needs of those skilled in the art in the layout.

[0021] In some scenarios, the user can pull the wire 30 so that the wire 30 extends out of the receiving cavity to adjust the length of the part of the wire 30 outside the housing 10. At this time, the wire winding assembly 20 can rotate under the traction of the wire 30, and then can be locked by the locking assembly 50 so that the wire winding assembly 20 no longer rotates, or the wire 30 no longer extends out of the receiving cavity. When it is necessary to wind or release the wire 30 again by the wire winding assembly 20, the locking assembly 50 can be unlocked.

[0022] Further, when the locking component 50 is unlocked, the winding component 20 can rotate to wind the wire 30 and traction the wire 30, so that the wire 30 enters the accommodating cavity at a high speed. At this time, the speed limiting component 40 cooperates with the winding component 20 to control the winding speed of the wire 30 by the winding component 20 within a safe speed range, reducing the risk of the wire 30 causing harm to the user due to being tractioned by the winding component 20.

[0023] Further, when the locking component 50 is unlocked, the wire 30 can be tractioned by the user, so that the wire 30 extends out of the accommodating cavity at a high speed. At this time, the speed limiting component 40 cooperates with the winding component 20 to control the releasing speed of the wire 30 by the winding component 20 within a safe speed range, reducing the risk of the wire 30 causing harm to the user due to being tractioned by the user.

[0024] Please refer to Figure 2 , Figure 2 is Figure 1 a schematic diagram of the frame of the wire winding mechanism 100 in some other embodiments of the illustrated embodiment. The wire winding mechanism 100 may further include a circuit board 60. The circuit board 60 may be a PCB (Printed Circuit Board), which is called a printed circuit board and also known as a printed wiring board. Of course, the circuit board 60 may also be a flexible circuit board. The wire 30 may be the above-mentioned data line or other conductive wire structures. The circuit board 60 may be electrically connected to the wire 30.

[0025] In some embodiments, the circuit board 60 may be disposed in the accommodating cavity of the housing 10 or outside the housing 10.

[0026] In some embodiments, the circuit board 60 may be fixed on the surface of the housing 10.

[0027] Please refer to Figure 3 and Figure 4 , Figure 3 is Figure 1 a three-dimensional structure diagram of the wire winding mechanism 100 in some embodiments of the illustrated embodiment, Figure 4 is Figure 3Exploded view of the wire winding mechanism 100 in some of the illustrated embodiments. The wire winding mechanism 100 may include a housing 10, a wire winding assembly 20, a wire 30, and a speed limiting assembly 40. The housing 10 may have a receiving cavity 101. The wire winding assembly 20 may be disposed within the receiving cavity 101. The wire winding assembly 20 may be used to wind the wire 30 such that the wire 30 is wound into a coil and stored within the receiving cavity 101. The wire 30 may also be released from the wire winding assembly 20 and extend out of the receiving cavity 101 so that a portion of the wire 30 is located outside the housing 10 for convenient use. The speed limiting assembly 40 is disposed between the wire winding assembly 20 and the housing 10 and cooperates with the wire winding assembly 20 to control the speed of winding and / or releasing the wire 30 within a safe speed range, reducing the risk of injury to the user caused by the wire 30 being pulled by the wire winding assembly 20 or the user.

[0028] The housing 10 may be a housing structure or a frame structure, and the specific form of the housing 10 may also be set according to the needs of those skilled in the art. The housing 10 may include a first housing 11 and a second housing 12. The first housing 11 and the second housing 12 may be connected to form the receiving cavity 101. In some embodiments, a portion of the receiving cavity 101 is disposed within the first housing 11 and a portion is disposed within the second housing 12. In some embodiments, the receiving cavity 101 may be disposed on the first housing 11, and the second housing 12 may cover and enclose the receiving cavity 101. In some embodiments, the receiving cavity 101 may be disposed on the second housing 12, and the first housing 11 may cover and enclose the receiving cavity 101.

[0029] Please refer to Figure 4 and Figure 5 , Figure 5 is Figure 4 A perspective view of the first housing 11 in another perspective in the illustrated embodiment. The first housing 11 may include a first plate body 111 and a first side wall 112. The first plate body 111 may be disposed opposite to the second housing 12. The first side wall 112 may be disposed on the first plate body 111 and extend toward the side of the second housing 12 to connect with the second housing 12, and thus may cooperate with the first plate body 111 and the second housing 12 to enclose the receiving cavity 101.

[0030] The first plate body 111 may be in a plate-like structure, and of course, it may also be other structures with thickness. The first plate body 111 may be a circular structure or a square structure. Of course, it may also be set according to the needs of those skilled in the art, and the specific structure of the first plate body 111 may not be limited herein.

[0031] The first plate body 111 may be provided with a rotating shaft 1111 on the side facing the second housing 12 to connect with the second housing 12 and cooperate with the wire winding assembly 20. In some embodiments, the rotating shaft 1111 may be located in the middle of the first plate body 111.

[0032] The first plate body 111 may be provided with mounting holes 1101 around the rotating shaft 1111, and an elastic member 1112 may be provided in the mounting holes 1101 to cooperate with the speed limiting assembly 40.

[0033] The number of the elastic members 1112 may be multiple and distributed around the rotating shaft 1111. In some embodiments, the multiple elastic members 1112 may be evenly distributed around the rotating shaft 1111. In some embodiments, the elastic members 1112 are provided in one-to-one correspondence with the mounting holes 1101 or the grooves, that is, one mounting hole 1101 or groove is provided with one elastic member 1112. In some embodiments, multiple elastic members 1112 may be provided in one mounting hole 1101 or groove.

[0034] In some embodiments, the elastic member 1112 may be formed by hollowing out the first plate body 111, thereby forming the mounting hole 1101. Of course, the elastic member 1112 and the mounting hole 1101 may also be formed when the first housing 11, such as the first plate body 111, is injection molded.

[0035] The elastic member 1112 may be made of an elastic material or a rigid material and can be bent to undergo elastic deformation. The elastic member 1112 may be in a plate-like structure or a strip-like structure, etc.

[0036] Please refer to Figure 4 and Figure 5 , the elastic member 1112 may have a free end 1114 and a connecting end 1113 in the extending direction, and may be connected to the hole wall of the mounting hole 1101 at the connecting end 1113, so that the mounting hole 1101 has the function of making way for the elastic member 1112. When a force is applied to the part of the elastic member 1112 between the free end 1114 and the connecting end 1113 or at the free end 1114, it bends with the connecting end 1113 as a fulcrum to undergo elastic deformation. The elastic member 1112 may bend outward of the accommodating cavity 101 to undergo elastic deformation.

[0037] In some embodiments, the elastic member 1112 may bend to one side in the axial direction of the mounting hole 1101 (which may also be the extending direction) or the axial direction of the rotating shaft 1111 to undergo elastic deformation.

[0038] Please refer to Figure 6 , Figure 6 is Figure 3 the cross-sectional view of the winding mechanism 100 at the line V-V in the shown embodiment. In some embodiments, the thickness of the elastic member 1112 gradually changes from the connecting end 1113 to the free end 1114 and may gradually become smaller. Furthermore, the elastic deformation ability of the elastic member 1112 can be improved. Compared with the position near the free end 1114, the elastic deformation ability of the position near the connecting end 1113 is relatively poor. Of course, the elastic member 1112 may also have a gradually changing thickness at least at the part where it cooperates with the speed limiting assembly 40.

[0039] The above-mentioned setting of the gradually changing thickness can form a space for accommodating the abutting member 41. In some scenarios, within this space, the distance between the elastic member 1112 and the winding disc 21, such as the rotating plate 211, can change with the gradual change of the thickness of the elastic member 1112. Furthermore, when the winding disc 21, such as the rotating plate 211, rotates, the abutting force between the speed limiting assembly 40 and the winding disc 21, such as the rotating plate 211, can be changed.

[0040] In some embodiments, at least on the surface of the elastic member 1112 close to the speed limiting assembly 40, at least on the partial surface cooperating with the speed limiting assembly 40, it can bend and extend outward from the accommodating cavity 101.

[0041] In some embodiments, at least on the surface of the elastic member 1112 close to the speed limiting assembly 40, at least on the partial surface cooperating with the speed limiting assembly 40, it can be a plane and extend outward from the accommodating cavity 101.

[0042] In some embodiments, due to the material limitation of the elastic member 1112, it is also possible to only make the elastic member 1112 elastically deform outward from the accommodating cavity 101, without limiting the specific structure of the elastic member 1112.

[0043] In some embodiments, based on the function of the mounting hole 1101, the first plate body 111 can also be provided with a groove to replace the mounting hole 1101, so that the elastic member 1112 is located in the groove, and the elastic member 1112 can elastically deform into the groove.

[0044] In some embodiments, based on the function of the mounting hole 1101, the elastic member 1112 can also be at least partially spaced from the first plate body 111 on the side of the first plate body 111 facing the second housing 12, so as to provide a space for the elastic member 1112 through the space between the elastic member 1112 and the first plate body 111. Of course, due to the material limitation of the elastic member 1112, the elastic member 1112 can be provided on the surface of the first plate body 111 on the side facing the second housing 12.

[0045] In some embodiments, the elastic member 1112 can also be connected to other parts of the first housing 11, such as the first plate body 111 or the first side wall 112. Further, the elastic member 1112 can partially extend into the mounting hole 1101 or the groove and cooperate with the speed limiting assembly 40.

[0046] Please refer to Figure 4 、 Figure 5 and Figure 6 , the first side wall 112 can surround the periphery of the rotating shaft 1111. In some embodiments, the first side wall 112 can extend from the edge of the first plate body 111 toward the side close to the second housing 12.

[0047] In some embodiments, an inlet / outlet 1102 may be provided on the first sidewall 112 so that the wire 30 extends out of or enters the accommodating cavity 101 through the inlet / outlet 1102. In some embodiments, the wire 30 passes through the inlet / outlet 1102, and thus is partially located inside the accommodating cavity 101 and partially located outside the accommodating cavity 101. In some embodiments, the inlet / outlet 1102 may be formed by enclosing with the first plate body 111 and the first sidewall 112. In some embodiments, the inlet / outlet 1102 may be formed by enclosing with the first plate body 111, the first sidewall 112, and the second housing 12.

[0048] A first snap structure 1121 may be provided on the first sidewall 112 for snap connection with the second housing 12. In some embodiments, the first snap structure 1121 may be a bayonet. In some embodiments, the first snap structure 1121 may be one or more, and may be formed by opening, hollowing out, or injection molding on the first sidewall 112. In some embodiments, the first sidewall 112 may also be connected to the second housing 12 in other forms such as screwing, welding, or bonding.

[0049] A first connecting ear 1122 may be provided on the first sidewall 112 for direct connection with the second housing 12, or connection in other forms such as screwing, welding, or bonding, and / or connection with other structures in the coiling mechanism 100 such as the outer shell, decorative shell, or protective shell through the first connecting ear 1122. Specifically, the first connecting ear 1122 can be used according to the needs of those skilled in the art.

[0050] Please refer to Figure 4 and Figure 6 , the second housing 12 may include a second plate body 121. The second plate body 121 may be disposed opposite to the first plate body 111 and may be connected to the first housing 11 such as the first sidewall 112, so as to enclose the accommodating cavity 101 with the first housing 11.

[0051] Fixing holes 1201 may be provided on the second plate body 121 for the rotation shaft 1111 to extend into, so as to reinforce the rotation shaft 1111 and connect the first housing 11 and the second housing 12. In some embodiments, the fixing holes 1201 may be replaced by fixing grooves or convex columns provided on the second plate body 121, so that the rotation shaft 1111 extends into the fixing groove, or the rotation shaft 1111 is inserted into the convex column, to reinforce the rotation shaft 1111. In some embodiments, the rotation shaft 1111 may be divided into two parts, which are coaxially arranged and connected, and one part is disposed on the first housing 11 and the other part is disposed on the second housing 12.

[0052] The second plate 121 may be provided with a second buckle structure 122 to be buckled with the first housing 11, such as the first buckle structure 1121, to achieve a detachable connection between the first housing 11 and the second housing 12. In some embodiments, the second buckle structure 122 may be a block. The block may extend into the first buckle structure 1121, such as a bayonet, for buckle connection.

[0053] A second connecting ear 123 may be provided on the second plate body 121 to be directly connected to the first shell body 11, such as the first connecting ear 1122, or to be connected by other means such as screwing, welding or bonding, and / or to other structures in the winding mechanism 100 such as an outer shell, a decorative shell or a protective shell through the second connecting ear 123. The specific use of the second connecting ear 123 can be determined according to the needs of technical personnel in this field.

[0054] It is understandable that the second plate 121 can also be provided with an elastic member 1112 in the same manner as the first plate 111. In addition, the second housing 12 can also be provided with a second side wall in the same manner as the first housing 11, and the matching mode of the second side wall and the second plate 121 can be involved in the matching mode of the first side wall 112 and the first plate 111, which will not be described in detail, and further, the second buckle structure 122 and the second connecting ear 123 can also be provided on the second side wall instead of on the second plate 121. Furthermore, the matching direction of the first buckle structure 1121 and the second buckle structure 122 is not limited to the matching mode of the block and the bayonet, and can also be other buckle-connectable structures known to those skilled in the art.

[0055] In some embodiments, the first housing 11 may be Figure 4 The second housing 12 is arranged in the same manner as in the embodiment of the present invention, and the second housing 12 can be arranged in the same manner as in the embodiment of the present invention. Figure 4 The arrangement is performed in the same manner as the arrangement of the first shell 11.

[0056] See also Figure 4 , the winding assembly 20 may include a winding drum 21 and a coil spring 22. The winding drum 21 may be rotatably connected to the housing 10 for winding or releasing the wire 30. The coil spring 22 may be connected to the housing 10 and the winding drum 21 respectively to provide power for the winding drum 21 to wind the wire 30, drive the winding drum 21 to rotate in a first direction or a second direction, and control the wire 30 entering and exiting the accommodating chamber 101 by controlling the rotation of the winding drum 21 relative to the housing 10. Of course, the coil spring 22 may also be replaced by a power source such as a motor or a torsion spring, a rubber band, etc. to drive the winding drum 21 to rotate. For example, a motor may be transmission-connected to the winding drum 21, for example, a torsion spring or a rubber band may be set in the manner of the coil spring 22. In some embodiments, the coil spring 22 may be omitted. In some embodiments, the first direction and the second direction are opposite. In some embodiments, the first direction may be Figure 4 The clockwise direction F1 in the second direction can be Figure 4the counterclockwise direction F2 therein. In some embodiments, the first direction may be Figure 4 the counterclockwise direction F2 therein, and the second direction may be Figure 4 the clockwise direction F1 therein.

[0057] In some embodiments, the user may pull the wire 30 so that the wire winding disc 21 rotates in the first direction. When the user does not pull the wire 30, the torsion spring 22 may drive the wire winding disc 21 to rotate in the second direction to wind the wire 30.

[0058] In some embodiments, the user may pull the wire 30 so that the wire winding disc 21 rotates in the second direction. When the user does not pull the wire 30, the torsion spring 22 may drive the wire winding disc 21 to rotate in the first direction to wind the wire 30.

[0059] The wire winding disc 21 may include a rotating plate 211 and a wire winding frame 212. The wire winding frame 212 is disposed on the rotating plate 211.

[0060] A rotating hole 2101 may be provided on the rotating plate 211 to be sleeved on the rotating shaft 1111, so that the rotating shaft 1111 passes through the rotating hole 2101, realizing the rotational connection between the wire winding disc 21 and the housing 10, such as the rotating shaft 1111, and enabling the rotating plate 211 to rotate around the axis of the rotating shaft 1111 and / or the axis of the rotating hole 2101.

[0061] The rotating hole 2101 may extend in the thickness direction h of the rotating plate 211 (see Figure 4 and Figure 6 ). That is, the rotating hole 2101 may extend in the thickness direction of the wire winding disc 21, such that the axis of the rotating shaft 1111 may be parallel to the thickness direction of the wire winding disc 21.

[0062] One side of the rotating plate 211 may be in abutting cooperation with the speed limiting assembly 40. In some embodiments, one side of the rotating plate 211 facing the elastic member 1112 is in abutting cooperation with the speed limiting assembly 40.

[0063] The wire winding frame 212 may be a frame structure or an annular structure. The wire winding frame 212 may be disposed on the side of the rotating plate 211 away from the speed limiting assembly 40. In some embodiments, the wire winding frame 212 may be disposed on the side of the rotating plate 211 facing the second housing 12, such as the second plate body 121.

[0064] The wire winding frame 212 may surround the rotating shaft 1111 or the rotating hole 2101. The outer side of the wire winding frame 212 may be used for winding the wire 30, and may wind or release the wire 30 when the wire winding disc 21 rotates. In some embodiments, the wire winding frame 212 may be omitted, and the wire 30 may be wound or released through the rotating plate 211.

[0065] Please refer to Figure 4 andFigure 8 , Figure 8 is Figure 4 a schematic structural view of the cooperation of the first housing 11 with the speed limiting component 40 and the torsion spring 22 in the illustrated embodiment. The torsion spring 22 is used to provide power for the wire winding component 20 so that the wire winding component 20 can wind the wire 30. One end of the torsion spring 22 can be fixed on the rotating shaft 1111 and wound around the rotating shaft 1111, and then the other end is fixed on the rotating plate 211 and / or the wire winding frame 212, so that the wire winding frame 212 can be arranged around the outside of the torsion spring 22. The arrangement of the wire winding frame 212 can isolate the wire 30 and the torsion spring 22.

[0066] In some embodiments, the winding direction of the torsion spring 22 can be the same as the extending direction of the connecting end 1113 to the free end 1114 of the elastic member 1112, and of course, it can also be different.

[0067] The wire 30 can be wound on the wire winding frame 212, and one end can be fixed on the wire winding frame 212 and can pass through the inlet / outlet 1102. In some embodiments, the winding direction of the wire 30 can be the same as the winding direction of the torsion spring 22. In some embodiments, the wire 30 can be wound on the rotating plate 211. In some embodiments, the winding directions of the wire 30 and the torsion spring 22 can both be the first direction. In some embodiments, the winding directions of the wire 30 and the torsion spring 22 can both be the second direction.

[0068] Please refer to Figure 4 and Figure 6 , Figure 8 , the speed limiting component 40 can include an elastic member 1112 and an abutting member 41. The elastic member 1112 can be a structure shared by the speed limiting component 40 and the housing 10. The abutting member 41 abuts between the elastic member 1112 and the wire winding disc 21, such as the rotating plate 211, and abuts against the elastic member 1112 and the wire winding disc 21, such as the rotating plate 211 respectively. The setting of the abutting member 41 can make the elastic member 1112 and the wire winding disc 21, such as the rotating plate 211, be arranged at intervals, and even make the part where the elastic member 1112 cooperates with the abutting member 41 be arranged at intervals from the wire winding disc 21, such as the rotating plate 211.

[0069] In some embodiments, the abutting member 41 can move relative to the elastic member 1112 and the wire winding disc 21, such as the rotating plate 211, in the third direction, that is, the speed limiting component 40 can move relative to the wire winding disc 21, such as the rotating plate 211, in the third direction.

[0070] In some embodiments, the third direction can be Figure 6 the direction F3 shown in Figure 6 , of course, only one embodiment of the third direction is shown, and it does not limit that the third direction can also be other directions for realizing the movement of the speed limiting component 40 relative to the wire winding disc 21, such as the rotating plate 211.

[0071] In some embodiments, when no abutting member 41 is provided between the elastic member 1112 and the winding disc 21, such as the rotating plate 211, that is, when the elastic member 1112 is not elastically deformed, in the third direction, the distance between the portion of the elastic member 1112 that cooperates with and abuts against the abutting member 41 on the winding disc 21, such as the rotating plate 211, and the winding disc 21, such as the rotating plate 211, gradually changes.

[0072] Please refer to Figure 6 , the distance D between the portion of the elastic member 1112 that cooperates with and abuts against the abutting member 41 on the winding disc 21, such as the rotating plate 211, and the winding disc 21, such as the rotating plate 211, gradually decreases in the direction from left to right and gradually increases in the direction from right to left. Furthermore, when the abutting member 41 is located at a position where the distance D is smaller, the elastic member 1112 elastically deforms toward the side away from the abutting member 41 to adapt to the abutting member 41. Compared with the case where the abutting member 41 is located at a position where the distance D is larger, the abutting member 41 will be given a greater acting force by the elastic member 1112. In addition, the gradual change of the distance D also facilitates the sliding of the abutting member 41 on the elastic member 1112. Furthermore, when the winding disc 21 rotates, it drives the abutting member 41 to slide on the elastic member 1112. For example, when the winding disc 21, such as the rotating plate 211, rotates at a high speed and drives the abutting member 41 to slide on the elastic member 1112 in the direction from right to left, the abutting force between the abutting member 41 and the winding disc 21, such as the rotating plate 211, can be gradually increased until a balanced position is reached, and the rotation speed of the winding disc 21, such as the rotating plate 211, is limited during this process.

[0073] In some scenarios, the gradual change of the distance can be formed by the cooperation of the surface of the elastic member 1112 on the side close to the speed limiting component 40. In some scenarios, the gradual change of the distance can be formed by the cooperation of the gradual change of the thickness of the elastic member 1112 between the connection end 1113 and the free end 1114.

[0074] In some embodiments, the abutting member 41 can abut against the winding disc 21, such as the rotating plate 211, in the axial direction of the rotating shaft 1111.

[0075] In some embodiments, the abutting member 41 can be structures such as a slider, a ball, or a roller. In some scenarios, when the abutting member 41 is a slider, sliding friction can be generated by the abutting force to limit the speed of the winding disc 21, such as the rotating plate 211. In some scenarios, when the abutting member 41 is a rotating body such as a ball or a roller, the rotating body can be rotated by the abutting force, roll on the elastic member 1112, and when the rotating body reaches a balanced position, the rotation speed of the winding disc 21, such as the rotating plate 211, can be limited at the balanced position.

[0076] When the winding reel 21 rotates, for example, the rotating plate 211 rotates around the rotating shaft 1111, the abutting member 41 slides on the elastic member 1112 under the drive of the rotating plate 211, so that the abutting member 41 can slide in the direction from the free end 1114 to the connecting end 1113 or in the direction from the connecting end 1113 to the free end 1114.

[0077] Please refer to Figure 7 , Figure 7 is Figure 6 a schematic structural view of the winding mechanism 100 in some other embodiments of the illustrated embodiment. When the abutting member 41 slides on the elastic member 1112 in the direction from the connecting end 1113 to the free end 1114, for example, the abutting member 41 moves from the position of the abutting member 41 represented by the dotted line to the position of the abutting member 41 represented by the solid line, and the elastic member 1112 changes from the elastic member 1112 represented by the dotted line to the elastic member 1112 represented by the solid line, and the elastic deformation becomes smaller, and then the abutting force on the abutting member 41 becomes smaller. Further, the abutting force of the abutting member 41 on the winding reel 21, such as the rotating plate 211, becomes smaller. When the abutting member 41 slides on the elastic member 1112 in the direction from the free end 1114 to the connecting end 1113, for example, the abutting member 41 moves from the position of the abutting member 41 represented by the solid line to the position of the abutting member 41 represented by the dotted line, and the elastic member 1112 changes from the elastic member 1112 represented by the solid line to the elastic member 1112 represented by the dotted line, and the elastic deformation becomes larger, and then the abutting force on the abutting member 41 becomes larger. Further, the abutting force of the abutting member 41 on the winding reel 21, such as the rotating plate 211, becomes larger. The setting of the speed limiting component 40 can adjust the abutting force between the abutting member 41 and the winding reel 21, such as the rotating plate 211, and then realize the adjustment of the frictional force between the abutting member 41 and the winding reel 21, such as the rotating plate 211. By changing the frictional force, the rotation of the winding reel 21, such as the rotating plate 211, can be hindered. In some embodiments, the cooperation of the winding reel 21, such as the rotating plate 211, the abutting member 41 and the elastic member 1112 can adjust the elastic deformation degree of the elastic member 1112 while adjusting the abutting force between the abutting member 41 and the winding reel 21, such as the rotating plate 211.

[0078] Please refer to Figure 4 and Figure 6, when the wire winding disc 21, for example, the rotating plate 211 rotates to release the wire 30, the abutting member 41 can slide on the elastic member 1112 in the direction from the free end 1114 to the connecting end 1113, reducing the frictional force between the abutting member 41 and the wire winding disc 21, for example, the rotating plate 211, and reducing the hindrance of the abutting member 41 to the rotation of the wire winding disc 21, for example, the rotating plate 211. When the wire winding disc 21, for example, the rotating plate 211 rotates to wind the wire 30, the abutting member 41 can slide on the elastic member 1112 in the direction from the connecting end 1113 to the free end 1114, increasing the frictional force between the abutting member 41 and the wire winding disc 21, for example, the rotating plate 211, increasing the hindrance of the abutting member 41 to the rotation of the wire winding disc 21, for example, the rotating plate 211, controlling the winding speed of the wire winding assembly 20 within a safe speed range, and reducing the risk of the wire 30 causing harm to the user due to being pulled by the wire winding assembly 20. In some embodiments, when the abutting member 41 is a structure such as a ball or a roller, it can roll while sliding. When the abutting member 41 is squeezed by the elastic member 1112 and the wire winding disc 21, for example, the rotating plate 211 and cannot slide on the elastic member 1112, the rotation of the wire winding disc 21, for example, the rotating plate 211 can be achieved by self-rotation.

[0079] Of course, in other embodiments, when the wire winding disc 21, for example, the rotating plate 211 rotates to release the wire 30, the abutting member 41 can slide on the elastic member 1112 in the direction from the connecting end 1113 to the free end 1114. When the wire winding disc 21, for example, the rotating plate 211 rotates to wind the wire 30, the abutting member 41 can slide on the elastic member 1112 in the direction from the free end 1114 to the connecting end 1113. Control the releasing speed of the wire winding assembly 20 within a safe speed range, and reduce the risk of the wire 30 causing harm to the user due to being pulled by the user.

[0080] It can be understood that the speed limiting component 40 is not limited to the cooperation mode of the elastic member 1112 and the abutting member 41, and can also be the cooperation mode of a support plate (replacing the elastic member 1112 and having a surface for the cooperation of the elastic member 1112 and the abutting member 41) and the abutting member 41 (the abutting member 41 can be made of an elastic material, can abut against the abutting member 41, and push the abutting member 41 to move on the support plate to realize the adjustment of the abutting force between the abutting member 41 and the wire winding disc 21, for example, the rotating plate 211), or even other structures well-known to those skilled in the art that can limit the speed by adjusting the abutting force with the wire winding disc 21, for example, the rotating plate 211, which will not be elaborated here.

[0081] In some embodiments, the abutting member 41 may be partially located within the mounting hole 1101 and is restricted by the hole wall of the mounting hole 1101. For example, the hole wall of the mounting hole 1101 includes a limiting portion 1115 which is located on opposite sides of the abutting member 41 and the elastic member 1112 and abuts against the abutting member 41 to limit the abutting member 41. Of course, when a groove replaces the mounting hole 1101, the abutting member 41 may be partially located within the groove. Of course, a limiting groove may be provided on the elastic member 1112, and the abutting member 41 is partially located within the limiting groove to limit the abutting member 41. At this time, it may not be necessary to use the mounting hole 1101 or the groove to limit the abutting member 41. In some embodiments, the limiting groove may extend in the direction from the free end 1114 to the connecting end 1113, and may extend in the direction in which the abutting member 41 moves relative to the elastic member 1112 and the winding disc 21, such as the rotating plate 211.

[0082] It can be understood that the speed limiting assembly 40 may also be provided between the second housing 12 and the winding assembly 20.

[0083] In addition, when Figure 3 and Figure 4 the locking assembly 50 is provided, the locking assembly 50 may be provided outside the housing 10 such that the locking assembly 50 extends into the housing 10 and abuts against the winding disc 21, such as the rotating plate 211, and by adjusting the abutting force between the locking assembly 50 and the winding disc 21, such as the rotating plate 211, locking or unlocking of the winding disc 21, such as the rotating plate 211, is achieved. Of course, when the locking assembly 50 extends into the housing 10, it may also abut against the wire 30, and by adjusting the abutting force between the locking assembly 50 and the wire 30, locking or unlocking of the wire 30 is achieved. Furthermore, the locking assembly 50 may also be provided within the housing 10 and partially outside the housing 10 and is touched and controlled by the user.

[0084] In some other scenarios, the locking assembly 50 may cooperate with the speed limiting assembly 40 to lock or unlock the winding disc 21, such as the rotating plate 211. For example, the locking assembly 50 may abut against the elastic member 1112 and apply a force to the elastic member 1112 such that the elastic member 1112 bends towards the side close to the winding disc 21, such as the rotating plate 211, to undergo elastic deformation, and by adjusting the abutting force between the abutting member 41 and the wire 30, locking or unlocking of the winding disc 21, such as the rotating plate 211, is achieved. Further, in some scenarios, the speed limiting assembly 40 may be a part of the locking assembly 50.
