[0002] In related technologies, automatic cable reel devices use a disconnect-type winding method for cables. The internal components of the reel device are prone to overheating, resulting in large current fluctuations when pulling the cable. Furthermore, automatic cable reel devices have numerous components, complex structures, and high costs. Additionally, automatic cable reels typically rotate in a vertical plane, occupying significant vertical space. Given the limited space in data centers, this can restrict the data center's layout. Utility Model Content

[0003] This application aims to solve at least one of the technical problems existing in the prior art. To this end, this application proposes a winding device that can effectively reduce the volume of the winding device in the longitudinal direction.

[0004] The winding device of this application embodiment includes:

[0005] A housing having a receiving cavity and a notch, the notch communicating the receiving cavity with the outside;

[0006] A rotating assembly includes a rotating shaft, a turntable, and a driving mechanism. The rotating shaft is rotatably mounted on the housing and at least partially located within the receiving cavity. The rotating shaft is vertically arranged. The turntable is mounted on the rotating shaft and disposed within the receiving cavity. The driving mechanism is connected to the rotating shaft and is used to drive the rotating shaft to rotate, thereby causing the turntable to rotate. The outer wall of the turntable is used for winding cables.

[0007] Furthermore, the rotating shaft has a first stepped surface extending axially along the rotating shaft and a first radial plane extending radially along the rotating shaft. The turntable includes a connecting portion, which is sleeved on the outer periphery of the first stepped surface and abuts against the first radial plane on one side. The rotating assembly includes a first pressure plate, which is sleeved on the outer periphery of the rotating shaft. The connecting portion is located between the first step and the first pressure plate.

[0008] Furthermore, the housing includes a mounting portion and a housing body disposed on the outer periphery of the mounting portion, the rotating shaft is rotatably mounted on the mounting portion, and the mounting portion is a groove recessed towards the turntable.

[0009] Furthermore, it also includes a cover plate, which is installed on the housing, and the cover plate and the groove enclose a mounting cavity, in which the drive mechanism is installed.

[0010] Furthermore, the rotating assembly includes a graphite washer disposed between the connecting portion and the mounting portion.

[0011] Furthermore, another graphite washer is provided on the side of the mounting part away from the turntable, and the graphite washer is located between the mounting part and another radial plane of the rotating shaft.

[0012] Furthermore, the turntable includes a turntable body and a first limiting structure disposed on the outer periphery of the turntable body, the first limiting structure being spirally coiled around the outer periphery of the turntable body.

[0013] Furthermore, the turntable also includes a second limiting structure, which is disposed on the edge of the outer wall of the turntable body.

[0014] Furthermore, the turntable includes a fixing structure, which is installed on the outer periphery of the turntable body and is used to fix one end of the cable.

[0016] The cable winding device according to the embodiments of this application has at least the following beneficial effects: In this embodiment, the rotating shaft is vertically arranged, and the turntable is mounted on the rotating shaft and can rotate around the rotating shaft. This allows the cable winding device to save space along the axial direction of the rotating shaft, thereby reducing the volume of the cable winding device along the axial direction of the rotating shaft. Simultaneously, with the rotating shaft vertically arranged and the turntable rotating around the rotating shaft, the weight of the cable can be evenly distributed in the circumferential direction of the turntable during the cable winding process.

Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0032] See Figures 1 to 3 This application discloses a winding device, including a housing 100 and a rotating assembly.

[0033] Specifically, the housing 100 has a receiving cavity 110 and a notch 120. The notch 120 connects the receiving cavity 110 to the outside. The notch 120 allows cables stored in the receiving cavity 110 to extend out of the receiving cavity 110, and also allows cables located outside the receiving cavity 110 to be stored inside the receiving cavity 110. The rotating assembly includes a rotating shaft 220, a turntable 210, and a drive mechanism 230. The rotating shaft 220 is rotatably mounted on the housing 100 and is at least partially located within the receiving cavity 110. The turntable 210 is mounted on the rotating shaft 220 and disposed within the receiving cavity 110. The rotating shaft 220 is vertically arranged. The drive mechanism 230 is connected to the rotating shaft 220 and is used to drive the rotating shaft 220 to rotate, thereby driving the turntable 210 to rotate. The outer wall of the turntable 210 is used for winding cables.

[0034] In this embodiment, the rotating shaft 220 is vertically arranged, and the turntable 210 is mounted on the rotating shaft 220 and rotates around the rotating shaft 220. This saves space in the winding device along the axial direction of the rotating shaft 220, thereby reducing the volume of the winding device along the axial direction of the rotating shaft 220. At the same time, with the rotating shaft 220 vertically arranged and the turntable 210 rotating around the rotating shaft 220, the weight of the cable can be evenly distributed in the circumferential direction of the turntable 210 during the cable winding process. This effectively reduces the possibility of abnormal wear or tipping of the rotating shaft 220 or the housing 100 due to uneven weight distribution of the cable in the turntable 210 in the axial direction of the rotating shaft 220.

[0035] In some embodiments of this application, see Figure 3 and Figure 4The rotating shaft 220 has a first step, which includes a first stepped surface 221 extending axially along the rotating shaft 220 and a first radial plane 222 extending radially along the rotating shaft 220. The turntable 210 includes a connecting portion 211, which is sleeved on the outer periphery of the first stepped surface 221 and one side of the connecting portion 211 abuts against the first radial plane 222. The rotating assembly includes a first pressure plate 240, which is sleeved on the outer periphery of the rotating shaft 220. The connecting portion 211 is located between the first step and the first pressure plate 240. In this embodiment, the rotating shaft 220 is a stepped shaft, and the connecting portion 211 is provided with a connecting hole that mates with the rotating shaft 220. The diameter of the connecting hole mates with the first stepped surface 221, and the side of the connecting portion 211 closest to the first radial plane 222 abuts against the first radial plane 222. Thus, the connecting part 211 can be clamped between the first pressure plate 240 and the first radial plane 222, thereby fixing the turntable 210 to the rotating shaft 220.

[0036] In one possible implementation, see Figure 3 and Figure 4 The winding device also includes a fastener 250, specifically a nut. The rotating shaft 220 is provided with an external thread on the side of the first pressure plate 240 away from the connecting part 211, which engages with the nut. The nut is threadedly connected to the rotating shaft 220. In this way, the first pressure plate 240 can be tightened and fixed by the nut, thereby fixing the turntable 210 to the rotating shaft 220.

[0037] In other embodiments, the first pressure plate 240 is fixedly connected to the rotating shaft 220 by welding.

[0038] In some embodiments of this application, the rotating shaft 220 is vertically arranged, and the turntable 210 rotates about the axis of the rotating shaft 220. Thus, the turntable 210 can rotate about the rotating shaft 220 in a horizontal plane. Therefore, the radial dimension of the turntable 210 in the rotating shaft 220 can be set as needed, and the axial dimension of the turntable 210 in the rotating shaft 220 can be appropriately reduced, thereby helping to reduce the size and volume of the winding device in the axial direction of the rotating shaft 220.

[0039] In some embodiments of this application, see Figure 3 and Figure 4The housing 100 includes a mounting portion 130 and a housing body disposed on the outer periphery of the mounting portion 130. A rotating shaft 220 is rotatably mounted on the mounting portion 130. Based on the outer surface of the housing body, the mounting portion 130 is a recessed groove facing the turntable 210. A drive mechanism 230 is mounted within this groove and drives the rotating shaft 220 to rotate. This effectively reduces the axial dimension of the winding device on the rotating shaft 220, allowing the winding device of this embodiment to be installed in equipment where vertical dimensional requirements for the winding device are present.

[0040] For example, in one possible implementation, the vertical height available for installing cable reel devices in conventional data centers is relatively small. However, the cable reel device of this embodiment has its spindle 220 vertically positioned, allowing the size of the turntable 210 to be distributed along the horizontal direction of the data center. Thus, the cable reel device of this embodiment is better suited for installation within the data center.

[0041] It is worth understanding that the winding device of this application embodiment can also be used in the fields of data center liquid cooling, energy storage liquid cooling, power industry, power system, electrical engineering and other technical fields, and is not limited thereto.

[0042] In this embodiment, see Figure 3 and Figure 4 The mounting portion 130 is provided with a mounting hole that mates with the rotating shaft 220. The rotating shaft 220 is a stepped shaft, and includes a second stepped surface 223 and a second radial plane 224. The second stepped surface 223 mates with the mounting hole of the mounting portion 130, and the second radial plane 224 abuts against the side of the mounting portion 130 away from the connecting portion 211 of the turntable 210. In this way, the rotating shaft 220 can be fixedly connected through the interaction of its own stepped radial plane and the connecting portion 211 of the turntable 210.

[0043] In some other embodiments, the winding device also includes a bearing, which is installed in the mounting hole of the aforementioned mounting part 130, and the inner ring of the bearing is fixedly connected to the rotating shaft 220.

[0044] In some embodiments of this application, see Figure 3 and Figure 4 The winding device also includes a cover plate 310, which is installed on the housing 100. The cover plate 310 and the groove enclose a mounting cavity, in which the drive mechanism 230 is installed. This helps to prevent foreign objects from contacting the drive mechanism 230 and helps to ensure the normal operation of the drive mechanism 230.

[0045] In some embodiments of this application, see Figure 3 and Figure 4The rotating assembly includes a graphite washer 260, which is disposed between the connecting portion 211 and the mounting portion 130. Specifically, the graphite washer 260 has a through hole through which the rotating shaft 220 passes, serving to fix the graphite washer 260. In this embodiment, the graphite washer 260 is disposed between the connecting portion 211 and the mounting portion 130 to prevent direct contact between the connecting portion 211 and the mounting portion 130; at the same time, the graphite washer 260 has good heat resistance and thermal conductivity, which can reduce heat accumulation, thereby effectively reducing localized heating inside the winding device and helping to reduce the probability of fire.

[0046] For some embodiments of this application, please refer to [link / reference]. Figure 3 and Figure 4 Another graphite washer 260 is provided on the side of the mounting part 130 away from the turntable 210. This graphite washer 260 is located between the mounting part 130 and another radial plane of the rotating shaft 220. Specifically, the graphite washer 260 is provided between the second radial plane 224 and the mounting part 130 to prevent the second radial plane 224 of the rotating shaft 220 from directly contacting the mounting part 130. At the same time, the graphite washer 260 has good heat resistance and thermal conductivity, which can reduce heat accumulation and thus effectively reduce the internal local heating of the winding device, helping to reduce the probability of fire.

[0047] In some embodiments of this application, see Figure 3 and Figure 4 The turntable 210 includes a turntable body 212 and a first limiting structure 213 disposed on the outer periphery of the turntable body 212. The first limiting structure 213 is spirally wound around the outer periphery of the turntable body 212. Specifically, the first limiting structure 213 spirally wound around the outer periphery of the turntable body 212, and adjacent segments of the first limiting structure 213 define cable placement slots 215. In this way, the cable can be wound orderly around the outer periphery of the turntable body 212, and the occurrence of cable tangling can be reduced, making it easier to pull out the cable.

[0048] In some embodiments of this application, see Figure 3 The turntable 210 also includes a second limiting structure 214, which is disposed on the edge of the outer wall of the turntable body 212. Specifically, the second limiting structure 214 is provided on both the upper and lower sides of the turntable body 212. In this way, the second limiting structure 214 can effectively reduce the possibility of cables detaching from the turntable 210.

[0049] In some embodiments of this application, see Figure 1The turntable 210 includes a fixing structure 216, which is installed on the outer periphery of the turntable 210 and is used to fix one end of the cable. In practical applications, after one end of the cable is pressed and fixed by the fixing structure 216, rotating the turntable 210 allows the cable to be wound around the outer periphery of the turntable 210.

[0050] In this embodiment, the fixing structure 216 includes a pressure block and a fastener 250. The fastener 250 is specifically a fixing bolt. The pressure block has a U-shaped notch, which is used to abut against the outer periphery of the cable. The fixing bolt is used to tighten the pressure block and fix it to the turntable body 212.

[0051] In some embodiments of this application, the drive mechanism 230 includes a spring, one end of which is connected to the housing 100, and the other end of which is connected to the rotating shaft 220. In practical applications, the spring can drive the rotating shaft 220 to rotate around its own axis, thereby causing the cable to be coiled around the outer circumference of the turntable 210. In this embodiment, using a spring to drive the rotating shaft 220 simplifies the drive structure and effectively simplifies the cable winding device.

[0052] It is understandable that the specific model or specification of the spring can be selected according to the required driving force of the rotating shaft 220, so that the winding device can wind cables of different diameters. For example, when the diameter of the cable being wound is greater than 8mm or other sizes, the force required to drive the cable to wind around the turntable 210 is relatively large. Therefore, the appropriate spring can be selected according to the required driving force so that the spring can drive the rotating shaft 220 to rotate, thereby winding the cable around the outer circumference of the turntable 210.

[0053] In some other embodiments of this application, when the force of the drive shaft 220 rotating and the force of the cable winding around the outer periphery of the turntable 210 are large, the drive mechanism 230 may include a drive motor, which drives the shaft 220 to rotate, thereby causing the cable to wind around the outer periphery of the turntable 210.

[0054] In some embodiments of this application, see Figures 1 to 3 The winding device also includes a support structure 320. Specifically, multiple support structures 320 are spaced apart on the outer periphery of the housing 100 to support the housing 100. This allows for a certain distance between the housing 100 and the support surface.

[0055] Conventional automatic cable reeling devices cannot automatically reel in cables with high current carrying capacity, and the diameter of the cable being reeled in is less than 8mm. Conventional automatic cable reeling devices have a disconnect reeling method, many parts, complex structure, and high cost. In addition, when the cable is working, the inside of the automatic cable reeling device is prone to heat generation, and the current fluctuates greatly during the pulling process.

[0056] In one possible implementation of this application, the winding device is used to wind up an entire section of cable; that is, the cable to be wound up by the winding device in this embodiment is a continuous cable without joints. When the cable is wound into the winding device, because the cable is continuous and without joints, the heating of all parts of the cable is uniform. Thus, the temperature inside the winding device can be kept stable, the current fluctuation of the cable during the pulling process is low, and the input signal is stable.

[0057] The embodiments of this application have been described in detail above with reference to the accompanying drawings. However, this application is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this application. Furthermore, unless otherwise specified, the embodiments and features described in the embodiments of this application can be combined with each other.
