Description

Technical Field

[0001] This utility model relates to the field of charging technology, specifically to a telescopic cable structure and charging equipment. Background Technology

[0002] Currently, retractable cable structures are widely used in household appliances such as power banks, vacuum cleaners, garment steamers, power tools, smart home devices, and outdoor work equipment in daily life and industrial production. Their core function is to achieve orderly storage and flexible extension of cables, avoid messy tangling, and improve the ease of use of equipment. Currently, the mainstream retractable cable structures on the market are mainly divided into two categories: manual and electric. Manual retractable cable structures often rely on a spring energy storage mechanism to achieve cable retrieval. For example, a pre-compressed spring drives the retraction shaft to rotate. When the user pulls the cable outward, the spring is further compressed to store energy. After releasing the cable, the spring releases energy to drive the shaft to reverse and complete the cable retrieval. However, this type of structure has significant limitations: firstly, the spring force gradually decreases with repeated use, leading to weaker retrieval strength and potential problems such as incomplete cable retraction or slow retrieval speed later on; secondly, the speed at which the spring releases energy during retrieval is difficult to control, often resulting in the cable end suddenly accelerating and impacting the equipment housing during retrieval. This not only generates significant noise but may also cause impact damage to the cable end or the internal structure of the equipment, shortening the product's lifespan. To address the shortcomings of manual retractable cable structures, electric retractable cable structures have gradually gained application. These structures directly drive the take-up shaft via a motor, achieving automatic cable retrieval without relying on spring energy storage, effectively avoiding problems caused by spring force decay. Furthermore, the take-up speed and force can be flexibly adjusted via the motor control module, resulting in a smoother take-up process. However, existing electric retractable cable structures still have design deficiencies: the motor and take-up shaft often use a fixed transmission connection (such as gear meshing or direct coupling). This connection method causes the cable's tension to drive the take-up shaft during the cable release process (i.e., when the user pulls the cable outwards), which in turn forces the motor rotor to rotate through the fixed transmission structure. Because the motor rotor has significant electromagnetic and mechanical resistance when there is no power supply, users need to overcome the motor resistance to complete the wire laying, which not only increases the difficulty of the wire laying operation and results in a poor user experience, but more importantly, when the motor rotor is forced to rotate in a non-driven state, a reverse induced current will be generated inside the motor. This current will not only cause energy loss, but may also impact the motor's winding coils, commutator and other core components. Long-term use can easily lead to a decline in the motor's insulation performance, accelerated wear of internal parts, significantly shorten the motor's service life, and increase the maintenance cost and failure risk of the equipment. Therefore, how to design a telescopic cable structure that can achieve automatic cable reeling by the motor, save energy, avoid the motor being forcibly driven during the cable unwinding process, reduce the difficulty of unwinding, and extend the life of the motor has become a technical problem that urgently needs to be solved in this field.

Detailed Implementation

[0034] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of protection of the present invention. Example 1:

[0035] Please see Figures 1-3 , Figure 1 A perspective view of an embodiment of the telescopic cable structure of this utility model is shown. In this embodiment, the telescopic cable structure includes a motor 100 and a first telescopic cable module 200.

[0036] The motor 100 is fixedly provided with a first one-way transmission component 120, and the first telescopic line module 200 is provided with a first one-way constraint component 210; the first one-way transmission component 120 and the first one-way constraint component 210 can be detachably connected.

[0037] When the telescopic cable structure is in the retracting state, the motor 100 rotates forward, the first one-way transmission member 120 drives the first one-way constraint member 210 to rotate forward, and the first telescopic cable module 200 rotates under the drive of the first one-way constraint member 210 to retract the cable. When the first telescopic cable module 200 is in the unwinding state under external force, the first one-way transmission member 120 and the first one-way constraint member 210 are slidably connected, the first telescopic cable module 200 rotates in reverse relative to the motor 100, and the motor 100 does not rotate with the first telescopic cable module 200.

[0038] In this embodiment of the invention, the first one-way transmission member 120 and the first one-way constraint member 210 are detachably connected, meaning their movements are separated. When the first telescopic line module 200 is in the unloading state under external force, the first one-way transmission member 120 is separated from the first one-way constraint member 210 and no longer moves with it. The two are slidably connected (slidable connection can mean that the first one-way transmission member 120 and the first one-way constraint member 210 are in contact and slide relative to each other), thereby allowing the first telescopic line module 200 to reverse relative to the motor 100 when it is in the unloading state under external force.

[0039] In other words, when the motor 100 rotates forward, the first one-way transmission member 120 can push the first one-way constraint member 210 to move together. When the motor 100 rotates in reverse, the first one-way transmission member 120 slides relative to the first one-way constraint member 210, and the first one-way transmission member 120 cannot push the first one-way constraint member 210 to move. It can be understood that the forward rotation of the motor 100 can be clockwise or counterclockwise, and correspondingly, the reverse rotation of the motor 100 can be counterclockwise or clockwise. Furthermore, this utility model embodiment does not specifically limit the specific structure of the first one-way transmission member 120 and the first one-way constraint member 210. When the motor 100 rotates forward, the first one-way transmission member 120 and the first one-way constraint member 210 can maintain a constraint structure, and both rotate forward together. When the motor 100 rotates in reverse, the first one-way transmission member 120 and the first one-way constraint member 210 are released from motion constraint, and the first one-way constraint member 210 can rotate in the opposite direction relative to the first one-way transmission member 120. This configuration enables automatic wire reeling via the motor, eliminating the need for motor rotation during wire unwinding, thus effectively extending motor life and saving energy.

[0040] In this embodiment of the invention, the telescopic cable structure further includes a first elastic component 300, which is elastically connected to the first telescopic cable module 200. The first elastic component 300 is disposed on the side of the first telescopic cable module 200 facing away from the motor 100. The first elastic component 300 includes a first fixing member 320 and a first elastic member 310. One end of the first elastic member 310 facing away from the first telescopic cable module 200 is connected to the first fixing member 320, and the other end of the first elastic member 310 is connected to the first telescopic cable module 200. The first fixing member 320 can be fixedly connected to the housing or other supporting components to constrain the first elastic member 310 between the first fixing member 320 and the first telescopic cable module 200. The first fixing member 320, the first elastic member 310, and the first telescopic line module 200 can be fixed together in various ways. For example, the first elastic member 310 can abut against the upper surface of the first telescopic line module 200 and the first fixing member 320. The upper end of the first elastic member 310 can also be fixedly connected to the first fixing member 320 and / or the upper surface of the first telescopic line module 200. This embodiment of the present invention does not impose specific limitations. The first elastic member 310 can be a spring.

[0041] In one of the ways, such as Figure 3As shown, the first telescopic cable module 200 may include a first telescopic cable protective shell 250. The first fixing member 320, the first elastic member 310, and the first telescopic cable module 200 can be fixed to each other. One end of the first fixing member 320 is fixedly connected to the shell, and the other end is fixedly connected to one end of the first elastic member 310. The other end of the first elastic member 310 is fixedly connected to the first telescopic cable protective shell 250.

[0042] In another embodiment, the telescopic cable structure further includes a first connecting shaft 130 fixedly connected to the first fixing member 320 and the motor, respectively. The first telescopic cable module 200 and the first elastic member 310 are threaded onto the first connecting shaft 130. Specifically, one end of the first connecting shaft 130 is fixedly connected to the upper end face of the motor 100, and the other end of the first connecting shaft 130 is connected to the first fixing member 320. The first elastic member 310 and the first rotating shaft 230 are sequentially sleeved onto the first connecting shaft 130.

[0043] When the first telescopic cable module 200 is in the winding state, the first elastic member 310 applies pressure to the first telescopic cable module 200, causing the first one-way transmission member 120 to drive the first one-way constraint member 210 to engage. The first one-way transmission member 120 drives the first one-way constraint member 210 to rotate forward, and the first telescopic cable module 200 rotates under the drive of the first one-way constraint member 210 to wind up the first telescopic cable module 200.

[0044] When the first telescopic cable module 200 is in the cable-laying state under external force, the first one-way transmission member 120 rotates under external force, causing the first telescopic cable module 200 to move axially toward the first elastic member 310 along the first connecting shaft 130, applying pressure to the first elastic member 310. This causes the first one-way transmission member 120 to move away from the first one-way constraint member 210 and enter a sliding connection state. The first telescopic cable module 200 rotates relative to the motor 100, but the motor 100 does not rotate with the first telescopic cable module 200. Figure 2 As shown, in a specific implementation of this utility model, the first one-way transmission member 120 is disposed on the upper end face of the motor 100, and one end of the first connecting shaft 130 is fixedly connected to the middle of the upper end face of the motor 100. As those skilled in the art will understand, the motor 100 includes a motor rotor and a motor stator. To achieve rotation, the first one-way transmission member 120 is fixedly disposed on the upper end face of the motor rotor, so that the first one-way transmission member 120 rotates when the motor rotor rotates. The motor 100 also includes a motor base 110, the bottom of which is fixedly connected to the housing.

[0045] The first telescopic cable module 200 further includes a first rotating shaft 230 and a first telescopic cable 220 wound on the first rotating shaft 230; the first one-way transmission member 120 is disposed on the end face of the motor 100 facing the first telescopic cable module 200; the end of the first rotating shaft 230 facing the motor 100 is provided with the first one-way constraint member 210, and the shape of the first one-way constraint member 210 is adapted to the shape of the first one-way transmission member 120.

[0046] Specifically, the first one-way constraint member 210 is fixedly disposed at the lower end of the first rotating shaft 230. The first elastic member 310 and the first rotating shaft 230 are sequentially sleeved on the first connecting shaft 130, and one end of the first elastic member 310 is connected to the first fixing member 320; the first rotating shaft 230 is disposed between the first elastic member 310 and the motor 100 so that the first one-way transmission member 120 is engaged with the first one-way constraint member 210. The first elastic member 310 can be a deformable elastic member such as a spring. The first telescopic line protective shell 250 is also disposed outside the first rotating shaft 230 and the first telescopic line 220. The first one-way transmission member 120 passes through the bottom of the first telescopic line protective shell 250 and exits from the top of the first telescopic line protective shell 250. The first elastic member 310 of the first one-way transmission member 120 is disposed between the protective shell and the first fixing member 320. The upper end of the first elastic element 310 can abut or be fixedly connected to the first fixing element 320, and the lower end of the first elastic element 310 abuts against the upper surface of the protective shell. When the telescopic cable structure is not in the winding or unwinding state, the first elastic element 310 can be in an undeformed state or a compressed state. When the telescopic cable structure is in the winding or unwinding state, the first elastic element 310 is in a compressed state.

[0047] in, Figure 5 It shows Figure 4 A magnified structural diagram at point A in the middle. (See diagram below.) Figure 3 As shown in the embodiment of this utility model, the first unidirectional constraint member 210 includes at least one first engaging portion, and the first unidirectional transmission member 120 includes at least one second engaging portion. The shape of the first engaging portion is adapted to the shape of the second engaging portion. The first engaging portion includes a first vertical tooth surface 2301 and a first inclined tooth surface 2302 inclined relative to the first vertical tooth surface 2301, and the first vertical tooth surface 2301 is connected to the first inclined tooth surface 2302. The second engaging portion includes a second vertical tooth surface 1201 and a second inclined tooth surface 1202 inclined relative to the second vertical tooth surface 1201, and the second vertical tooth surface 1201 is connected to the second inclined tooth surface 1202.

[0048] Specifically, the first unidirectional constraint member 210 meshes with the first unidirectional transmission member 120, the first vertical tooth surface 2301 of the first unidirectional constraint member 210 is in contact with the second vertical tooth surface 1201 of the first unidirectional transmission member 120, and the first inclined tooth surface 2302 is in contact with the second inclined tooth surface 1202.

[0049] The number of the first meshing portion and the second meshing portion can both be multiple; the second vertical tooth surface 1201 or the second inclined tooth surface 1202 of one second meshing portion forms a groove structure with the second inclined tooth surface 1202 or the second vertical tooth surface 1201 of an adjacent second meshing portion; one first meshing portion extends into the groove formed by the second vertical tooth surface 1201 of one second meshing portion and the second inclined tooth surface 1202 of an adjacent second meshing portion. One second meshing portion extends into the groove formed by the first vertical tooth surface 2301 of one first meshing portion and the first inclined tooth surface 2302 of an adjacent first meshing portion. With this configuration, when the motor 100 rotates forward, the first one-way constraint member 210 rotates in a direction where the first vertical tooth surface 2301 fits more tightly against each other, and the first meshing part and the second meshing part are engaged together. The first one-way transmission member 120 drives the first one-way constraint member 210 to rotate, thereby driving the first rotating shaft 230 to rotate so that the first telescopic line module 200 can take in the line. At this time, the second one-way transmission member 150 and the second one-way constraint member 410 disengage from each other, so as not to affect the second telescopic line module 400.

[0050] The included angle formed by the first vertical tooth surface 2301 and the first inclined tooth surface 2302 is the first included angle, and the included angle formed by the second vertical tooth surface 1201 and the second inclined tooth surface 1202 is the second included angle. In order to improve the engagement and disengagement effect of the first unidirectional constraint member 210 with the first unidirectional transmission member 120, the difference between the first included angle and the second included angle is set to be -2° to 2°.

[0051] Preferably, the first included angle is the same as the second included angle, so that the first engaging portion and the second engaging portion can engage better.

[0052] Specifically, the first engagement portion and the second engagement portion of the first one-way constraint member 210 and the first one-way transmission member 120 may include only one engagement portion. When only one engagement portion is included, the engagement portion may be of a larger size, so that the first vertical tooth surface of the first one-way constraint member 210 and the second vertical tooth surface of the first one-way transmission member 120 can fit together over a larger area, thereby engaging more reliably. When there are multiple engagement portions, they can be arranged in a gear shape, with the first vertical tooth surface 2301 of each engagement portion of the first one-way constraint member 210 fitting together with the second vertical tooth surface 1201 of each engagement portion of the first one-way transmission member 120, and the first inclined tooth surface 2302 of each engagement portion of the first one-way constraint member 210 fitting together with the second inclined tooth surface 1202 of each engagement portion of the first one-way transmission member 120.

[0053] Preferably, the vertical tooth surfaces of the first unidirectional constraint member 210 and the first unidirectional transmission member 120 are in contact with each other, and the inclined tooth surfaces are in contact with each other, with the same inclination angle and opposite direction. This embodiment of the invention does not specifically limit the inclination angle of the inclined tooth surfaces. In one specific implementation, to achieve better separation during the line laying process, the inclination angle between the first inclined tooth surface 2302 and the first vertical tooth surface 2301 can be set to be greater than or equal to 45 degrees.

[0054] With the above settings, when the motor 100 rotates forward, the first one-way constraint member 210 rotates in a direction where the vertical tooth surfaces of the meshing parts are more closely fitted together, and the meshing parts are engaged together. The first one-way transmission member 120 drives the first one-way constraint member 210 to rotate, thereby driving the first rotating shaft 230 to rotate to take in the line.

[0055] When the first telescopic cable module 200 is subjected to external force for cable release, it drives the first rotating shaft 230 to reverse, causing the inclined tooth surfaces of the meshing parts to disengage. The first rotating shaft 230 compresses the first elastic member 310, and the first one-way constraint member 210 disengages from the first one-way transmission member 120. This achieves automatic cable reeling driven by the motor 100 during forward rotation, while the motor 100 does not operate during manual cable release, thus saving energy and reducing motor 100 wear. Example 2:

[0056] Please see Figures 5-7 This utility model embodiment also provides a telescopic line structure. For example... Figure 5 and Figure 6 As shown, this embodiment differs from Embodiment 1 in that the telescopic line structure of this utility model further includes at least one second telescopic line module 400, wherein... Figure 5 A schematic diagram of the structure of the second telescopic line module 400 with a second telescopic line protective shell; Figure 6This is a schematic diagram after removing the protective shell of the second telescopic cable. A second one-way transmission member 150 is fixedly mounted on the motor 100; a second one-way constraint member 410 is mounted on the second telescopic cable module 400; the second one-way transmission member 150 and the second one-way constraint member 410 are detachably connected. When the second telescopic cable module 400 is in the winding state, the motor 100 reverses direction, and the second one-way transmission member 150 drives the second one-way constraint member 410 to reverse direction as well. The second telescopic cable module 400 rotates under the influence of the second one-way constraint member 410 to wind up the cable. When the second telescopic cable module 400 is in the unwinding state under external force, the second one-way transmission member 150 and the second one-way constraint member 410 are slidably connected, and the second telescopic cable module 400 rotates relative to the motor 100, while the motor 100 does not rotate with the second telescopic cable module 400. This configuration allows for independent control of two telescopic cables using a single motor, improving efficiency and reducing size.

[0057] Among them, such as Figure 7 As shown, the telescopic cable structure also includes a second elastic component 500; the first elastic component 300 is elastically connected to the first telescopic cable module 200, and the second elastic component 500 is elastically connected to the second telescopic cable module 500. The telescopic cable structure of this embodiment, by setting the first telescopic cable module 200, the first elastic component 300, the second telescopic cable module 400, and the second elastic component 500, allows one motor to separately perform the take-up and unload of the two telescopic cable modules without mutual interference. The second elastic component 500 includes a second elastic element 510, which can be a spring. In this embodiment, the telescopic cable structure also includes a connecting shaft, one end of which is connected to the motor 100, and the first telescopic cable module 200, the first elastic component 300, the second telescopic cable module 400, and the second elastic component 500 are sequentially sleeved on the connecting shaft. This embodiment does not specifically limit the specific structure of the connecting shaft; it is understood that as long as it allows the motor to rotate and serves a connecting function, it is acceptable.

[0058] In one embodiment, the connecting shaft includes a first connecting shaft 130 as shown in Embodiment 1, and a second connecting shaft 140. The motor 100 includes a motor base 110. The telescopic cable structure also includes a transmission disk 1402 and a fixed disk 1401. The transmission disk 1402 is located between the motor base 110 and the fixed disk 1401. One end of the first connecting shaft 130 is connected to the motor base 110, and the other end of the first connecting shaft 130 is connected to the transmission disk 1402. The first telescopic cable module 200 and the first elastic component 300 are sequentially sleeved on the first connecting shaft 130. One end of the second connecting shaft 140 is connected to the transmission disk 1402, and the other end of the second connecting shaft 140 is connected to the fixed disk 1401.

[0059] The first elastic component 300 includes a first fixing member 320 and a first elastic member 310. One end of the first elastic member 310 facing away from the first telescopic cable module 200 is connected to the first fixing member 320, and the other end of the first elastic member 310 near the first telescopic cable module 200 is connected to the first telescopic cable module 200. The first telescopic cable module 200, the first elastic member 310 and the first fixing member 320 are sequentially sleeved on the first connecting shaft 130. One end of the first connecting shaft 130 is connected to the motor base 110, and the other end of the first connecting shaft 130 is connected to the transmission disk 1402.

[0060] The second elastic component 500 includes a second elastic element 510. One end of the second elastic element 510 facing away from the second telescopic cable module 400 is connected to the fixed disk 1401, and the other end of the second elastic element 510 is connected to the second telescopic cable module 400. The second telescopic cable module 400 and the second elastic element 510 are sequentially sleeved on the second connecting shaft 140. One end of the second connecting shaft 140 is connected to the transmission disk 1402, and the other end of the second connecting shaft 140 is connected to the fixed disk 1401. Under normal conditions, the second elastic element 510 provides a spring force to the second telescopic cable module 400, causing the second unidirectional constraint member 410 of the second telescopic cable module 400 to abut against the second unidirectional transmission member 150.

[0061] In this embodiment, the first one-way transmission member 120 is disposed on the end face of the motor base 110 facing the first telescopic cable module 200. The second telescopic cable module 400 further includes a second rotating shaft 430 and a second rotating shaft 420 wound around the second rotating shaft 430. The second one-way transmission member 150 is disposed on the end face of the transmission disk 1402 facing the second telescopic cable module 400; the second telescopic cable module 400 includes a second rotating shaft 430 and a second rotating shaft 420 wound around the second rotating shaft 430; a second one-way constraint member 410 is disposed at the end of the second rotating shaft 430 facing the motor 100, and the shape of the second one-way constraint member 410 is adapted to the shape of the second one-way transmission member 150. Under the elastic force of the second elastic member 510, the second one-way constraint member 410 and the second one-way transmission member 150 abut against each other. In this embodiment, the first unidirectional constraint member 210 and the second unidirectional constraint member 410 have opposite constraint directions. The constraint direction refers to the constraint on the rotation direction.

[0062] It is understood that the first unidirectional constraint member 210 and the second unidirectional constraint member 410 have opposite constraint directions, meaning that the first unidirectional constraint member 210 and the second unidirectional constraint member 410 constrain the rotation direction of the telescopic line module shaft in different ways.

[0063] When the motor 100 reverses, the second one-way transmission member 150 can drive the second one-way constraint member 410 to reverse, causing the second rotating shaft 430 to rotate and take in the wire; at the same time, the first one-way constraint member 210 slides with the first one-way transmission member 120. Under the constraint of the first one-way constraint member 210, the first one-way transmission member 120 cannot drive the second one-way constraint member 410 to reverse, so that the first rotating shaft 230 does not rotate and take in the wire.

[0064] When the motor 100 rotates forward, the first one-way transmission member 120 can drive the first one-way constraint member 210 to rotate forward, so that the first shaft 230 rotates to take in the line; at the same time, the second one-way transmission member 150 can prevent the second one-way constraint member 410 from rotating in reverse, so that the second shaft 430 does not rotate to take in the line.

[0065] In one specific implementation of this embodiment, the first unidirectional constraint member 210 includes at least one first engaging portion, and the first unidirectional transmission member 120 includes at least one second engaging portion, the shape of the first engaging portion being adapted to the shape of the second engaging portion. The second unidirectional constraint member 410 includes at least one third engaging portion, and the second unidirectional transmission member 150 includes at least one fourth engaging portion, the shape of the fourth engaging portion being adapted to the shape of the second engaging portion. The engagement direction between the first and second engaging portions is opposite to the engagement direction between the third and fourth engaging portions.

[0066] The first meshing portion includes a first vertical tooth surface 2301 and a first inclined tooth surface 2302 inclined relative to the first vertical tooth surface 2301, wherein the first vertical tooth surface 2301 is connected to the first inclined tooth surface 2302. The second meshing portion includes a second vertical tooth surface 1201 and a second inclined tooth surface 1202 inclined relative to the second vertical tooth surface 1201, wherein the second vertical tooth surface 1201 is connected to the second inclined tooth surface 1202. The third meshing portion includes a third vertical tooth surface 4101 and a third inclined tooth surface 4102 inclined relative to the third vertical tooth surface 4101, wherein the third vertical tooth surface 4101 is connected to the third inclined tooth surface 4102. The fourth meshing portion includes a fourth vertical tooth surface 1501 and a fourth inclined tooth surface 1502 inclined relative to the fourth vertical tooth surface 1501, wherein the fourth vertical tooth surface 1501 is connected to the fourth inclined tooth surface 1502. Wherein, the first inclined tooth surface 2302 and the second inclined tooth surface 1202 extend in the same direction, and the first inclined tooth surface 2302 and the third inclined tooth surface 4102 extend in opposite directions; the third inclined tooth surface 4102 and the fourth inclined tooth surface 1502 extend in the same direction, and the second inclined tooth surface 1202 and the fourth inclined tooth surface 1502 extend in opposite directions.

[0067] Specifically, such as Figure 8 As shown, the first unidirectional constraint member 210 meshes with the first unidirectional transmission member 120, the first vertical tooth surface 2301 of the first unidirectional constraint member 210 is in contact with the second vertical tooth surface 1201 of the first unidirectional transmission member 120, and the first inclined tooth surface 2302 is in contact with the second inclined tooth surface 1202.

[0068] The number of the first meshing portion and the second meshing portion can both be multiple; the second vertical tooth surface 1201 or the second inclined tooth surface 1202 of one second meshing portion forms a groove structure with the second inclined tooth surface 1202 or the second vertical tooth surface 1201 of an adjacent second meshing portion; one first meshing portion extends into the groove formed by the second vertical tooth surface 1201 of one second meshing portion and the second inclined tooth surface 1202 of an adjacent second meshing portion. One second meshing portion extends into the groove formed by the first vertical tooth surface 2301 of one first meshing portion and the first inclined tooth surface 2302 of an adjacent first meshing portion.

[0069] With this configuration, when the motor 100 rotates forward, the first one-way constraint member 210 rotates in a direction where the first vertical tooth surface 2301 fits more tightly against each other, and the first meshing part and the second meshing part are engaged together. The first one-way transmission member 120 drives the first one-way constraint member 210 to rotate, thereby driving the first rotating shaft 230 to rotate so that the first telescopic line module 200 can take in the line. At this time, the second one-way transmission member 150 and the second one-way constraint member 410 disengage from each other, so as not to affect the second telescopic line module 400.

[0070] like Figure 9 As shown, the second one-way constraint member 410 meshes with the second one-way transmission member 150, and the third vertical tooth surface 4101 of the second one-way constraint member 410 and the fourth vertical tooth surface 1501 of the second one-way transmission member 150 are in contact with each other, and the third inclined tooth surface 4102 of the second one-way constraint member 410 and the fourth inclined tooth surface 1502 of the second one-way transmission member 150 are in contact with each other.

[0071] The number of the third meshing portion and the fourth meshing portion can both be multiple; the third vertical tooth surface 4101 or the third inclined tooth surface 4102 of one third meshing portion forms a groove structure with the fourth inclined tooth surface 1502 or the fourth vertical tooth surface 1501 of an adjacent fourth meshing portion; one fourth meshing portion extends into the groove formed by the third vertical tooth surface 4101 of one third meshing portion and the third inclined tooth surface 4102 of an adjacent third meshing portion. With this configuration, when the motor 100 reverses, the second one-way constraint member 410 rotates in a direction where it is more tightly engaged with the fourth vertical tooth surface 1501. The third and fourth meshing parts are engaged together. The second one-way transmission member 150 drives the second one-way constraint member 410 to rotate, thereby driving the second rotating shaft 430 to rotate so that the second telescopic cable module 400 can take in the cable. At this time, the first one-way transmission member 120 disengages from the first one-way constraint member 210, thus not affecting the first telescopic cable module 200. When the motor 100 rotates forward, the second one-way constraint member 410 rotates in a direction where the inclined tooth surfaces are engaged with each other, causing the fourth meshing part to gradually disengage from the groove formed by the third vertical tooth surface 4101 of the third meshing part and the third inclined tooth surface 4102 of the adjacent third meshing part, thereby compressing the second elastic member 510 and gradually disengaging it. With this configuration, when the motor 100 rotates forward, the second one-way constraint member 410 rotates along the direction in which the inclined tooth surfaces are in contact with each other, and the third and fourth meshing parts gradually disengage. The second one-way transmission member 150 cannot drive the second one-way constraint member 410 to rotate. At this time, the first one-way transmission member 120 and the first one-way constraint member 210 engage with each other to take up the first telescopic line module 200, so as not to affect the second telescopic line module 400.

[0072] The angle formed by the first vertical tooth surface 2301 and the first inclined tooth surface 2302 is the first included angle, and the angle formed by the second vertical tooth surface 1201 and the second inclined tooth surface 1202 is the second included angle. To improve the engagement and disengagement effect between the first unidirectional constraint member 210 and the first unidirectional transmission member 120, the difference between the first included angle and the second included angle is set to -2° to 2°. The angle formed by the third vertical tooth surface 4101 and the third inclined tooth surface 4102 is the third included angle, and the angle formed by the fourth vertical tooth surface 1501 and the fourth inclined tooth surface 1502 is the fourth included angle. The difference between the third included angle and the fourth included angle is -2° to 2°.

[0073] Preferably, the first included angle is the same as the second included angle, so that the first meshing part and the second meshing part can mesh better. Preferably, the third included angle is the same as the fourth included angle, so that the third meshing part and the fourth meshing part can mesh better. Preferably, the vertical tooth surfaces of the first unidirectional constraint member 210 and the first unidirectional transmission member 120 are in contact with each other, and the inclined tooth surfaces are in contact with each other, with the same inclination angle and opposite direction. This utility model embodiment does not specifically limit the inclination angle of the inclined tooth surface. In a specific implementation, in order to achieve better separation in the line-laying state, the inclination angle of the first inclined tooth surface 2302 and the first vertical tooth surface 2301 can be set to be greater than or equal to 45 degrees, and the inclination angle of the second inclined tooth surface 1202 and the second vertical tooth surface 1201 can be set to be greater than or equal to 45 degrees.

[0074] With the above settings, when the motor 100 rotates forward, the first one-way constraint member 210 rotates in a direction where the vertical tooth surfaces of the meshing parts are more closely fitted together, and the meshing parts are engaged together. The first one-way transmission member 120 drives the first one-way constraint member 210 to rotate, thereby driving the first rotating shaft 230 to rotate to take in the line.

[0075] Preferably, the vertical tooth surfaces of the second unidirectional constraint member 410 and the second unidirectional transmission member 150 are in contact with each other, and the inclined tooth surfaces are in contact with each other, with the same inclination angle and opposite direction. This embodiment of the invention does not specifically limit the inclination angle of the inclined tooth surfaces. In one specific implementation, to achieve better separation during the wire laying state, the inclination angle of the third inclined tooth surface 4102 and the third vertical tooth surface 4101 can be set to be greater than or equal to 45 degrees, and the inclination angle of the fourth inclined tooth surface 1502 and the fourth vertical tooth surface 1501 can be set to be greater than or equal to 45 degrees.

[0076] With the above configuration, when the motor 100 reverses, the second one-way constraint member 410 rotates in a direction where the vertical tooth surfaces of the meshing parts fit together more tightly, and the meshing parts are engaged together. The second one-way transmission member 150 drives the second one-way constraint member 410 to rotate, thereby driving the second rotating shaft 430 to rotate to take in the line.

[0077] When the motor 100 reverses, the second one-way transmission member 150 drives the second one-way constraint member 410 to rotate, thereby driving the second rotating shaft 430 to rotate and retract the line into the second telescopic cable module 400. At this time, the first one-way transmission member 120 and the first one-way constraint member 210 disengage from each other, thus not affecting the first telescopic cable module 200. When the second telescopic cable module 400 is subjected to external force to release the line, it drives the second rotating shaft 430 to reverse, compressing the second elastic member 510, and the second one-way constraint member 410 disengages from the second one-way transmission member 150. A transmission disk 1402 is provided on the second connecting shaft 140. This transmission disk is located near the end of the second connecting shaft 140 that connects to the first fixing member 320, and is at a predetermined distance from this end to form a torque transmission structure. This allows for better torque transmission while reducing the size of the component.

[0078] As will be understood by those skilled in the art, the motor 100 includes a motor rotor and a motor stator, and the first one-way transmission member 120 and the first connecting shaft 130 are fixedly arranged on the upper end face of the motor rotor to enable rotation.

[0079] In this embodiment of the present invention, the first rotating shaft 230 is a hollow shaft, and the first rotating shaft 230 is sleeved on the first connecting shaft 130. The first connecting shaft 130 is at a preset distance from the first rotating shaft in a direction perpendicular to the axial direction, so that when the motor reverses, the first telescopic cable module 200 will not rotate due to the rotation of the first connecting shaft 130.

[0080] A second connecting shaft 140 is fixedly connected above the first fixing member 320 of the first connecting shaft 130, and a second telescopic cable module 400 is sleeved on the second connecting shaft 140. The first elastic member 310 and the second elastic member 510 are springs; the springs are in a compressed state when the cable is retracted or released. With this arrangement, when the motor 100 rotates forward, the first one-way constraint member 210 rotates in a direction where the vertical tooth surfaces of the meshing parts are more tightly engaged, and the meshing parts are locked together. The first one-way transmission member 120 drives the first one-way constraint member 210 to rotate, thereby driving the first rotating shaft 230 to rotate so that the first telescopic cable module 200 retracts the cable. At this time, the second one-way transmission member 150 disengages from the second one-way constraint member 410, so as not to affect the second telescopic cable module 400.

[0081] When the motor 100 reverses, the second one-way transmission member 150 drives the second one-way constraint member 410 to rotate, thereby driving the second rotating shaft 430 to rotate and retract the line into the second telescopic cable module 400. At this time, the first one-way transmission member 120 and the first one-way constraint member 210 disengage from each other, thus not affecting the first telescopic cable module 200. When the second telescopic cable module 400 is subjected to external force to release the line, it drives the second rotating shaft 430 to reverse, compressing the second elastic member 510, and the second one-way constraint member 410 disengages from the second one-way transmission member 150. The transmission disk 1402 on the second connecting shaft 140 is located near the end of the second connecting shaft 140 connected to the first fixing member 320, and is at a predetermined distance from this end to form a torque transmission structure. This allows for better torque transmission while reducing the size of the component.

[0082] This embodiment achieves independent control of multiple retractable cable modules through the above-described configuration, overcoming the limitations of traditional methods that may require multiple motors and independent control systems for cable retraction and deployment. Traditional methods not only increase structural complexity but also significantly raise manufacturing costs and power consumption. In contrast, this embodiment establishes a transmission connection between multiple retractable cable components and the motor, enabling two cable modules to automatically retract using only one motor. This allows for the efficient and reliable integration of two independently usable retractable cables within a limited space.

[0083] Example 3: like Figure 10 As shown in the figure, this utility model embodiment also provides a charging device, which includes the telescopic cable structure described in any of the foregoing embodiments. The specific structure of the telescopic cable structure is largely the same as that in the foregoing embodiments, and will not be described again here.

[0084] The charging device also includes a housing; a mounting component is provided inside the housing, and the telescopic cable connector is used to fix the telescopic cable structure, which is fixed to the mounting component. At least one retractable button 650 is provided on the housing, and a circuit board 660 is provided inside the housing. The circuit board 660 may also include a control circuit and a charging circuit. Specifically, the housing may include an upper housing 610 and a lower housing 620. The mounting component, including an upper mounting component 630 and a lower mounting component 640, is fixed to the housing. The circuit board 660, the telescopic cable structure, the upper mounting component 630, and the lower mounting component 640 are disposed within the housing. The upper mounting component 630 is fixedly connected to the second fixing part of the second connecting shaft in the telescopic cable structure, and the lower mounting component 640 is fixedly connected to the motor base, thereby fixing the telescopic cable structure to the housing. The circuit board 660 may be disposed on the same circuit board as the charging circuit. To reduce the overall size of the charging device, the telescopic cable structure is disposed on one side of the circuit board, and the charging head of the telescopic cable passes through an opening in the housing and is disposed outside the housing. The control circuit is electrically connected to both the take-up button and the motor, and is used to send a forward or reverse rotation signal to the motor according to the take-up button information, so that the motor rotates forward or reverse. In this embodiment, the charging device also includes a charging power supply and / or a charging head for providing power.

[0085] This utility model embodiment uses a motor to control the winding of multiple telescopic lines on the telescopic line structure, eliminating the need for motor rotation during winding. This effectively extends the lifespan of the charging device's motor and saves energy.
