[0033] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0034] The specific technical features described in the specific embodiments can be combined in any suitable manner without contradiction. For example, different combinations of specific technical features can form different embodiments and technical solutions. To avoid unnecessary repetition, the various possible combinations of the specific technical features in this application will not be described separately.

[0035] In the following description, the terms "first," "second," etc., are used merely to distinguish different objects and do not indicate that the objects have the sameness or relationship. It should be understood that the directional descriptions "above," "below," "outside," and "inside" refer to the orientation under normal use conditions, while "left" and "right" refer to the left and right directions shown in the corresponding diagrams, which may or may not be the left and right directions under normal use conditions.

[0036] It should be noted that the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Unless otherwise specified, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element. "A plurality of" means two or more.

[0037] Please refer to Figure 1 and Figure 2 This application provides an ultra-thin multi-layer cable reel 1, which includes a housing assembly 10, a mounting base 20, and at least two cable reel assemblies 30.

[0038] It should be noted that in the embodiments of this application, "at least two" refers to two or more.

[0039] Please refer to Figure 2 The housing assembly 10 includes a first housing portion 11 and a second housing portion 12 arranged along a first direction.

[0040] It should be noted that the first direction refers to Figure 2 The direction indicated by the first arrow in the middle.

[0041] The mounting base 20 is disposed between the first housing portion 11 and the second housing portion 12 in a first direction. The mounting base 20 encloses the first housing portion 11 along a first side in the first direction to form a first space 1a, and the mounting base 20 encloses the second housing portion 12 along a second side in the first direction to form a second space 1b. It can be understood that the mounting base 20 can enclose both the first housing portion 11 to form the first space 1a and the second housing portion 12 to form the second space 1b. The first space 1a and the second space 1b share a single mounting base 20, which not only improves the utilization rate of the mounting base 20, but also makes the distance between the first space 1a and the second space 1b along the first direction closer. This reduces the size of the ultra-thin multi-layer cable winder 1 in the first direction, making the ultra-thin multi-layer cable winder 1 compact, easy to carry and transport.

[0042] Please refer to Figure 2 , Figure 5 and Figure 6 The cable winding assembly 30 includes a core 31 and a data cable 32.

[0043] One end of the data cable 32 extends out of the housing assembly 10. Understandably, the end of the data cable 32 passing through the housing assembly 10 is for the user to pull.

[0044] The end of the data cable 32 that extends out of the housing assembly 10 has an interface for connecting electronic devices. Users can electrically connect electronic devices via the data cable 32, for example, to charge the electronic devices.

[0045] It should be noted that there is no limit to the specific number of interfaces; for example, it can be one, two, or three, etc. There are no restrictions on the specific type of interface; for example, it can be Type-C, Lightning, Micro-USB, or Type-A, etc.

[0046] The wheel core 31 can rotate relative to the outer casing assembly 10 and is used to wind the data cable 32. Understandably, when the data cable 32 is not being pulled or used, the data cable 32 is wound around the wheel core 31 for easy storage and carrying. When the data cable 32 is pulled out by an external force, the data cable 32 extends and drives the wheel core 31 to rotate clockwise, increasing the length of the data cable 32 extending out of the outer casing assembly 10, making it easier for the user to make electrical connections to electronic devices using the data cable 32. When the wheel core 31 rotates counterclockwise, the wheel core 31 drives the data cable 32 to retract into the inner part of the outer casing assembly 10 to store the data cable 32 for easy carrying.

[0047] It should be noted that forward rotation refers to the rotation of the wheel core 31 along the extension direction of the data cable 32, while reverse rotation refers to the rotation of the wheel core 31 along the retraction direction of the data cable 32.

[0048] At least one winding assembly 30 is housed in a first space 1a, and at least one winding assembly 30 is housed in a second space 1b. The following description uses an example of one winding assembly 30 being housed in the first space 1a and one winding assembly 30 being housed in the second space 1b.

[0049] It is understood that the two cable winding assemblies 30 are respectively housed in the first space 1a and the second space 1b. The two cable winding assemblies 30 can operate independently. Users can electrically connect the data lines 32 of the two cable winding assemblies 30 to different electronic devices, increasing the application scenarios of the ultra-thin multi-layer cable winder 1. For example, the interface of the data line 32 of one cable winding assembly 30 is used to charge one electronic device, and the interface of the data line 32 of the other cable winding assembly 30 is used to charge another electronic device. Users can use the two cable winding assemblies to charge two different electronic devices.

[0050] In related technologies, cable winders using two winding assemblies are constructed by housing the two winding assemblies in two different housings and then joining the two housings together using snaps and slots. The joining of the two housings increases the size of the cable winder in the joining direction, making it inconvenient for users to carry.

[0051] The ultra-thin multi-layer cable winder 1 of this application embodiment forms two independent spaces (i.e., the first space 1a and the second space 1b) by sharing a base plate 23 with the first shell portion 11 and the second shell portion 12. This allows users to meet their needs for electrical connection to different electronic devices by using the data cable 32 of the cable winding assembly 30 in different spaces, thus increasing the usage scenarios of the ultra-thin multi-layer cable winder 1. The base plate 23 serves as a shared structure that encloses the first space 1a and the second space 1b, eliminating the need for additional connectors. This makes the structure of the ultra-thin multi-layer cable winder 1 compact, reduces the size of the ultra-thin multi-layer cable winder 1 in the first direction, and makes it easy to carry.

[0052] For example, the ultra-thin multilayer cable reel 1 includes a circuit board disposed inside the housing assembly 10. The circuit board is used for conductive contact with an external power source, and the other end of the data cable 32 is connected to the circuit board. That is, the circuit board serves as the input terminal of the ultra-thin multilayer cable reel 1, used for contact with an external power source and for transmitting electrical energy, enabling the data cable 32 to power electronic devices.

[0053] In some embodiments, please refer to Figure 1 and Figure 2 The first housing 11 has a first cable outlet 11a, which communicates with the first space 1a. Thus, the data cable 32 of the winding assembly 30 located in the first space 1a can extend out from the first cable outlet 11a.

[0054] For example, please refer to Figure 1 and Figure 2 The second housing 12 has a second cable outlet 12a, which communicates with the second space 1b. Thus, the data cable 32 of the cable winding assembly 30 located in the second space 1b can extend from the second cable outlet 12a.

[0055] It should be noted that the specific dimensions of the first cable outlet 11a and the second cable outlet 12a are not limited, as long as they allow the data cable 32 to extend or retract, but do not allow the interface of the data cable 32 to retract. This ensures that during the retraction process, the interface of the data cable 32 does not retract into the housing assembly 10, keeping the interface of the data cable 32 always outside the housing assembly 10, making it convenient for the user to pull the data cable 32.

[0056] For example, the ultra-thin multi-layer cable reel 1 includes flexible protective elements, with the edges of the first cable outlet 11a and / or the second cable outlet 12a provided with flexible protective elements. This reduces the likelihood of the data cable 32 being scratched by the edges of the cable outlets during pulling or retraction, extending the lifespan of the data cable 32, and also makes pulling the data cable 32 smoother, improving the user experience.

[0057] It should be noted that the above-mentioned flexible protective component setting schemes include the following: First, the flexible protective component is set on the edge of the first outlet 11a; Second, the flexible protective component is set on the edge of the second outlet 12a; Third, flexible protective components are set on both the edge of the first outlet 11a and the edge of the second outlet 12a.

[0058] It should be noted that the specific material of the flexible protective component is not limited; for example, it can be silicone.

[0059] It should be noted that the specific structure of the mounting base 20 is not limited.

[0060] In some embodiments, please refer to Figure 3 and Figure 4 The mounting base 20 is an integral structure. This improves the structural strength of the mounting base 20, ensuring the stability of the first space 1a and the second space 1b formed by the mounting base 20, the first shell 11, and the second shell 12, respectively, thereby ensuring the stability of the ultra-thin multilayer winding device 1.

[0061] For example, please refer to Figure 3 and Figure 4The mounting base 20 includes a base plate 23, which abuts against the first housing portion 11 and the second housing portion 12 on both sides along the first direction. It is understood that the base plate 23 is plate-shaped and has a small dimension along the first direction, resulting in a closer distance between the first housing portion 11 and the second housing portion 12 along the first direction, leading to a compact structure and facilitating a reduction in the size of the ultra-thin multilayer winding device 1 in the first direction.

[0062] It should be noted that the specific manner in which the base plate 23 is connected to the first shell portion 11 and the second shell portion 12 is not limited. For example, the base plate 23 has protrusions on both sides along the first direction, and the first shell portion 11 and the second shell portion 12 have grooves. The protrusions and grooves cooperate with each other to fix the first shell portion 11 and the second shell portion 12 on the base plate 23.

[0063] In some embodiments, please refer to Figure 3 and Figure 4 The mounting base 20 also includes a first side plate 21 and a second side plate 22. The first side plate 21 is disposed along the edge of the base plate 23 and extends towards a first side in a first direction, while the second side plate 22 is disposed along the edge of the base plate 23 and extends towards a second side in the first direction. The first side plate 21 is abutted against the first shell portion 11 in the first direction, and the second side plate 22 is abutted against the second shell portion 12 in the first direction. This provides sufficient space in the first direction for the connection between the mounting base 20 and the first shell portion 11 and the second shell portion 12, thereby improving the strength of the connection between the first shell portion 11 and the second shell portion 12 and the mounting base 20.

[0064] It should be noted that the specific docking method between the first side plate 21 and the first shell portion 11 is not limited. For example, one of the first side plate 21 and the first shell portion 11 may have a protrusion, and the other may have a groove. The protrusion and the groove cooperate to achieve docking between the first side plate 21 and the first shell portion 11. Similarly, the specific docking method between the second side plate 22 and the second shell portion 12 is not limited. For example, one of the second side plate 22 and the second shell portion 12 may have a protrusion, and the other may have a groove. The protrusion and the groove cooperate to achieve docking between the second side plate 22 and the second shell portion 12.

[0065] In some embodiments, the outer surface of the ultra-thin multi-layer cable winder 1 has at least two perforated areas 20a. At least one perforated area 20a connects to the external environment and the first space 1a, and at least one perforated area 20a connects to the external environment and the second space 1b. External airflow can enter the interior of the ultra-thin multi-layer cable winder 1 through the perforated areas 20a, carrying away the heat accumulated inside the ultra-thin multi-layer cable winder 1 to dissipate heat.

[0066] It should be noted that the specific method of forming the hollowed-out area 20a is not limited.

[0067] For example, please refer to Figure 3 and Figure 4 The first side plate 21 has a first notch 21a, which penetrates the end face of the first side plate 21 along a first direction. After the first shell portion 11 is joined with the first side plate 21, it encloses the first notch 21a to form a first hollow area, which connects the first space 1a and the external environment. The second side plate 22 has a second notch 22a, which penetrates the end face of the second side plate 22 along a second direction. After the second shell portion 12 is joined with the second side plate 22, it encloses the second notch 22a to form a second hollow area, which connects the second space 1b and the external environment. Thus, the shapes of the first notch 21a and the second notch 22a are simple, eliminating the need for deep holes or core pulling during manufacturing. This simplifies the formation of the hollow area 20a and reduces the manufacturing difficulty of the ultra-thin multi-layer winding device 1.

[0068] For example, please refer to Figure 3 and Figure 7 The wheel core 31 has a first ring portion 31a on the side facing the base plate 23 along the first direction, and the base plate 23 has a second ring portion 23a on the side facing the wheel core 31 along the first direction. The first ring portion 31a and the second ring portion 23a cooperate with each other, forming a circular track during the rotation of the wheel core 31, allowing the other to slide along the circular track. This improves the smoothness of the wheel core 31's rotation when the user pulls the data cable 32, reduces the noise generated by the wheel core 31's rotation, and enhances the user experience.

[0069] In some embodiments, please refer to Figure 3 and Figure 4 The mounting base 20 includes a base plate 23 and mounting shafts 24 disposed on both sides of the base plate 23. The wheel core 31 is sleeved on the outer periphery of the mounting shaft 24 and rotates around the mounting shaft 24. It can be understood that the mounting shaft 24 can play a positioning role for the wheel core 31, so that the wheel core 31 can rotate along a predetermined trajectory to ensure the stability of the wheel core 31 during rotation.

[0070] It should be noted that the specific structure of the wheel core 31 is not limited.

[0071] In some embodiments, please refer to Figures 5 to 9The wheel core 31 includes a wheel drum 311. The side wall of the wheel drum 311 has a locking port 311a. The data cable 32 includes a first end 32a and a second end 32b. The first end 32a extends out of the outer shell, and the second end 32b extends through the locking port 311a into the interior of the wheel drum 311 and is fixed to the wheel drum 311. Understandably, the second end 32b of the data cable 32 is fixed inside the reel drum 311. When the user pulls the data cable 32 wound on the reel core 31 to its maximum length, the tension on the data cable 32 has a component force in the radial direction outward towards the reel drum 311. Under the action of the component force, the data cable 32 will contact the drum side wall of the reel drum 311. The drum side wall has a certain structural strength. The drum side wall of the reel drum 311 will apply force to the data cable 32 to resist the force of the user's pulling force, which can reduce the possibility of the data cable 32 falling off the reel drum 311 under a large pulling force and improve the reliability of the ultra-thin multi-layer cable winder 1.

[0072] It should be noted that the specific thickness of the side wall of the reel drum 311 is not limited.

[0073] It should be noted that the cross-section of the roller drum 311 is annular.

[0074] In some embodiments, please refer to Figure 8 and Figure 9 The core 31 includes a clamping plate 312, which is located inside the drum 311. The clamping plate 312 and the drum sidewall of the drum 311 are arranged radially at intervals to form a clamping groove 31b. The second end 32b of the data cable 32 is located in the clamping groove 31b. It can be understood that the clamping groove 31b formed by the clamping plate 312 and the inner wall of the drum 311 can fix the second end 32b of the data cable 32, further reducing the possibility of the data cable 32 falling off the drum 311 under large tensile force, and improving the reliability of the ultra-thin multi-layer cable winder 1.

[0075] For example, please refer to Figure 8 and Figure 9 On the plane perpendicular to the axial direction of the drum 311, the clamping plate 312 is in the shape of an arc concentric with the drum 311. This makes the shape of the clamping plate 312 reasonable, which facilitates the formation of an arc-shaped clamping groove 31b between the clamping plate 312 and the side wall of the drum 311, allowing the data cable 32 to fit better against the groove wall of the clamping groove 31b.

[0076] It should be noted that the axial direction of the drum 311 refers to... Figure 8 The first direction in the middle.

[0077] For example, please refer to Figure 6The locking opening 311a is located on one side of the clamping groove 31b along the winding direction of the data cable 32. This allows the data cable 32 to be wound directly after passing through the clamping groove 31b and the locking opening 311a, reducing the possibility of the data cable 32 bending during the winding process.

[0078] For example, please refer to Figure 8 and Figure 9 The wheel core 31 includes at least two wheel side plates 313, which are disposed at both ends of the wheel drum 311 along the axial direction. The wheel side plates 313 extend radially along the wheel drum 311 and protrude from the side wall of the wheel drum 311. Thus, when the wheel core 31 winds the data cable 32, the two wheel side plates 313 can constrain the data cable 32 wound on the wheel drum 311, reducing the possibility of the data cable 32 falling off the wheel drum 311 and improving the reliability of the wheel core 31 winding the data cable 32.

[0079] In some embodiments, please refer to Figure 2 , Figure 5 and Figure 6 The cable winding assembly 30 includes a coil spring 33 disposed within the reel drum 311. The coil spring 33 provides a restoring force for the reel drum 311 to rotate in the direction of retracting the data cable 32. Understandably, during the extension of the data cable 32, the data cable 32 drives the reel drum 311 to rotate forward. The coil spring 33 stores elastic potential energy. When it is necessary to retract the data cable 32, the coil spring 33 uses the stored elastic potential energy to drive the reel drum 311 to rotate in the reverse direction, causing the reel drum 311 to retract the data cable 32 into the housing assembly 10. Furthermore, the coil spring 33 is disposed radially within the reel drum 311, preventing interference with the winding of the data cable 32 and resulting in a compact structure.

[0080] It should be noted that the specific setting of the coil spring 33 is not limited.

[0081] In some embodiments, please refer to Figure 5 and Figure 6 The wheel drum 311 is sleeved on the mounting shaft 24. One end of the coil spring 33 is connected to the wheel drum 311, and the other end of the coil spring 33 is connected to the mounting shaft 24. In this way, the mounting shaft 24 can support the coil spring 33. When the wheel drum 311 rotates around the mounting shaft 24 under the action of external force, one end of the coil spring 33 rotates with the wheel drum 311, while the other end remains stationary, causing deformation. This allows the coil spring 33 to store elastic potential energy. When the coil spring 33 releases the elastic potential energy, it drives the wheel drum 311 to rotate in the opposite direction to restore its original shape.
