Description

Technical Field

[0001] This invention relates to the field of cable storage, and in particular to a cable storage device, a window air conditioner base station, and a window air conditioner system. Background Technology

[0002] Traditional wire winding devices typically employ a motor-driven gear system, using multiple gears to reduce speed and increase torque. This converts the high-speed, low-torque motion output by the motor into the low-speed, high-torque rotation required by the turntable, thus optimizing tension control and speed uniformity during the wire winding process.

[0003] However, when the motor stops working, if the user manually drags the wire or other external forces pull it and cause the turntable to rotate in the opposite direction, the turntable's own inertia or sudden load will force the gear system to reverse the transmission. This will not only easily aggravate tooth surface wear and significantly affect the service life of the transmission mechanism, but also, under the condition of large instantaneous impact load, there is a risk of exceeding the strength design limit of the gear material, which may lead to tooth breakage or tooth fracture. Summary of the Invention

[0004] In view of the shortcomings of the prior art, the purpose of the present invention is to provide a wire storage device, a window air conditioner base station, and a window air conditioner system.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0009] A drive source is connected to the power gear, and the drive source is configured to drive the power gear to rotate in a first direction or a second direction in opposite directions.

[0010] An elastic component is connected to the transmission gear, and the elastic component can elastically deform as the transmission gear moves;

[0011] Wherein, the power gear rotates along the first direction and links with the transmission structure, so that the transmission structure drives the transmission gear to approach the output gear to connect with the output gear and cause the output gear to drive the winding reel component to rotate along the winding direction. The power gear rotates along the second direction and links with the transmission structure, so that the elastic component returns to its original deformation and drives the transmission gear away from the output gear to disconnect from the output gear.

[0012] In the above technical solution, the transmission structure includes:

[0013] A guide portion is disposed on one of the power gear and the transmission gear, and the guide portion is provided with a first guide slope and a second guide slope with opposite extending directions;

[0014] A sliding part is disposed on the other of the power gear and the transmission gear. When the power gear rotates in the first direction, the sliding part slides along the first guide slope, driving the transmission gear to move axially closer to the output gear; when the power gear rotates in the second direction, the sliding part slides along the second guide slope, causing the transmission gear to move axially away from the output gear under the action of the elastic member.

[0015] In any of the above technical solutions, the power gear is constructed as a sleeve structure, the outer wall of the sleeve structure is provided with a tooth structure that meshes with the drive source, and the inner wall of the sleeve structure is constructed with a convex wall, the two opposite sidewalls of the convex wall forming the first guide slope and the second guide slope.

[0016] The transmission gear has an insert portion that is inserted into the sleeve structure. The outer wall of the insert portion has protruding ridges that match the number of protruding walls, and the protruding ridges form the sliding portion.

[0017] In any of the above technical solutions, the transmission gear is constructed with a base plate structure, the base plate structure has the embedded part on the side facing the power gear, and the base plate structure has a first transmission gear structure on the side facing the output gear;

[0018] The output gear is provided with a second transmission gear structure adapted to mesh with the first transmission gear structure, and each tooth of the first transmission gear structure and the second transmission gear structure is configured as an axisymmetric structure.

[0019] In any of the above technical solutions, the elastic component is constructed as a cylindrical structure, and the transmission gear is connected to one end of the elastic component.

[0020] In any of the above technical solutions, the elastic component includes a soft rubber part, the peripheral sidewall of which is constructed with a bending structure that can be folded in the axial direction, and the bending structure can guide the soft rubber part to be compressed / unfolded in a regular manner.

[0021] In any of the above technical solutions, one end of the soft rubber part is provided with an annular groove in the axial direction, and the periphery of the transmission gear extends into the annular groove.

[0022] In any of the above technical solutions, the circumference of the transmission gear is provided with a plurality of circumferentially spaced protrusions, the protrusions being located in the annular groove and abutting against the annular groove.

[0023] In any of the above technical solutions, one of the output gear and the power gear is located inside the elastic component and has a radial clearance between it and the inner peripheral wall of the elastic component.

[0024] The above-mentioned technical solutions also include:

[0025] A control device is communicatively connected to the drive source. The control device is configured to control the drive source to drive the power gear to rotate in the second direction for a preset time based on the signal fed back by the detection device that the wire is fully retracted.

[0026] The above-mentioned technical solutions also include:

[0027] The detection device is communicatively connected to the control device, and is adapted to detect whether the wire has been properly stored and send the detection result to the control device.

[0028] In another aspect, the present invention provides a window-type base station, comprising:

[0029] The base station itself is used to store and / or clean the window unit;

[0030] The cable storage device as described in any of the above technical solutions is disposed on the base station body.

[0031] In another aspect, the present invention provides a window system, comprising:

[0032] Window unit;

[0033] As described in any of the above technical solutions, the window unit can be detachably installed in the window unit base station;

[0034] The cable has one end connected to the cable reel component of the cable storage device and the other end connected to the window unit.

[0035] The wire winding device of this invention drives a power gear to rotate in both directions via a drive source. The rotational motion is converted into axial displacement of the transmission gear through a transmission structure, thereby automatically controlling the engagement and disengagement of the transmission gear and the output gear. During forward rotation, the transmission structure pushes the transmission gear to overcome the resistance of the elastic component and move axially forward, achieving reliable engagement with the output gear and continuous wire winding. During reverse rotation, the movement of the transmission structure and the release of the elastic component work in tandem, guiding the transmission gear to move smoothly axially out, quickly and completely disengaging from the transmission connection with the output gear. This design allows the power transmission link to be actively and controllably cut off after wire winding is completed, leaving the reel component in a free state. At this point, dragging the wire only requires overcoming minimal resistance, achieving automatic drive for the winding action and convenient and smooth wire unwinding operation.

[0049] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0050] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the scope of protection of the invention is not limited to the specific embodiments disclosed below.

[0051] The wire storage device 10 of some embodiments of the present invention is described below with reference to the accompanying drawings.

[0052] like Figure 1 and Figure 2 As shown, an embodiment of the present invention provides a cable storage device 10, which can be used to store various flexible linear objects, such as cables, data cables, ropes, etc. The cable storage device 10 includes a cable reel component 100 and a drive component 200.

[0053] The reel component 100 is rotatably configured to store linear objects. Specifically, one end of the wire is fixed to the reel component 100, which can be driven to rotate clockwise or counterclockwise. In one embodiment, when the reel component 100 rotates clockwise, the wire is gradually wound around it, thus storing the wire. When it rotates counterclockwise, the wire is gradually released. Alternatively, the reel component 100 can be designed to rotate counterclockwise to wind the wire and rotate clockwise to release it.

[0054] The drive component 200 includes an output gear 210, a power gear 220, a transmission gear 230, a drive source 240, and an elastic component 250. The output gear 210 is connected to the winding reel component 100 for transmission. In one specific embodiment, the output gear 210 and the winding reel component 100 are coaxially distributed. A first meshing structure is provided at the central axis of the output gear 210, and a second meshing structure is provided at the central axis of the winding reel component 100. The first meshing structure and the second meshing structure mesh, thereby enabling the output gear 210 to transmit torque to the winding reel component 100.

[0055] A transmission structure 260 is provided between the drive gear 220 and the transmission gear 230. Specifically, the transmission structure 260 is used to move the transmission gear 230 axially. More specifically, the drive gear 220 can convert the rotational motion of the transmission gear 230 into axial motion through the transmission structure 260, so that the transmission gear 230 can rotate under the rotational drive of the drive gear 220 or rotate while moving axially.

[0056] It is particularly important to emphasize that the present invention does not impose any restrictions on the specific physical implementation of the transmission structure 260. It can adopt any structural form such as inclined plane slider, spiral groove, cam, etc. Any mechanical device, mechanism or combination thereof that can reliably convert the rotational motion of the power gear 220 into the axial linear motion of the transmission gear 230, regardless of its specific form or name, as long as it is based on the same basic principle of rotational-axial conversion and directional response, falls within the broad scope of the transmission structure 260 described in the present invention.

[0057] The drive source 240 is connected to the power gear 220. More specifically, the drive source 240 includes a drive motor. The drive motor and the power gear 220 are directly connected or indirectly connected through a set of transmission gears 230. The drive source 240 is configured to drive the power gear 220 to rotate in opposite directions, either a first direction or a second direction. Specifically, the first direction is one of clockwise and counterclockwise, and the second direction is the other of clockwise and counterclockwise.

[0058] The drive gear 220 rotates along the first direction to link the transmission structure 260, causing the transmission structure 260 to drive the transmission gear 230 closer to the output gear 210 for transmission connection, and causing the output gear 210 to drive the winding reel component 100 to rotate along the winding direction. The drive gear 220 rotates along the second direction to link the transmission structure 260, causing the elastic component 250 to recover its deformation and drive the transmission gear 230 away from the output gear 210 to disconnect from the output gear 210.

[0059] The wire winding device 10 of the present invention drives the power gear 220 to rotate in both directions via a drive source 240, and converts the rotational motion into the axial displacement of the transmission gear 230 via a transmission structure 260, thereby automatically controlling the engagement and disengagement of the transmission gear 230 and the output gear 210. During forward rotation, the transmission structure 260 pushes the transmission gear 230 to overcome the resistance of the elastic component 250 and move axially forward, achieving reliable engagement with the output gear 210 and continuous wire winding. During reverse rotation, the movement of the transmission structure 260 and the release of the elastic component 250 work in concert, guiding the transmission gear 230 to move smoothly axially out, quickly and completely disengaging from the transmission connection with the output gear 210. This design allows the power transmission link to be actively and controllably cut off after wire winding is completed, and the reel component 100 is then in a free state. At this time, dragging the wire only requires overcoming a small resistance, achieving automatic drive of the winding action and convenient and smooth wire unwinding operation.

[0060] like Figure 3 and Figure 4 As shown, in some embodiments, the transmission structure 260 includes a guide portion 261 and a sliding portion 262. The guide portion 261 is disposed on one of the drive gear 220 and the transmission gear 230, and the guide portion 261 has a first guide slope 2611 and a second guide slope 2612 extending in opposite directions. The sliding portion 262 is disposed on the other of the drive gear 220 and the transmission gear 230. When the drive gear 220 rotates in a first direction, the sliding portion 262 slides along the first guide slope 2611, driving the transmission gear 230 axially closer to the output gear 210; when the drive gear 220 rotates in a second direction, the sliding portion 262 slides along the second guide slope 2612, causing the transmission gear 230 to axially move away from the output gear 210 under the action of the elastic member 250.

[0061] When the power gear 220 rotates forward, the sliding part 262 slides along the first guide slope 2611, reliably converting the rotational power into an axial thrust on the transmission gear 230, allowing it to smoothly move into engagement. When the power gear 220 rotates in reverse, the sliding part 262 slides along the second guide slope 2612. Its movement trajectory provides clear guidance and space for the release of the elastic component 250, enabling the transmission gear 230 to smoothly move out and disengage along a predetermined path, ensuring the certainty, smoothness, and reliability of the engagement and disengagement actions and the overall mechanism.

[0062] Furthermore, the power gear 220 is configured as a sleeve structure 221. The outer wall of the sleeve structure 221 is provided with a tooth structure 222 that meshes with the drive source 240. The inner wall of the sleeve structure 221 is provided with a protruding wall 223. The two opposite side walls of the protruding wall 223 are formed as a first guide slope 2611 and a guide slope. The transmission gear 230 is configured with an insert portion 231. The insert portion 231 is inserted into the sleeve structure 221. The outer wall of the insert portion 231 is provided with protruding ribs 2311 that match the number of protruding walls 223. The protruding ribs 2311 are formed as sliding portions 262.

[0063] During operation, the drive source 240 drives the power gear 220 to rotate, and the convex wall 223 moves relative to the convex ridge 2311. Through the contact and sliding between the convex wall 223 and the convex ridge 2311, the rotational torque of the sleeve structure 221 is converted into an axial force on the convex ridge 2311, thereby precisely driving the transmission gear 230 to move linearly along its axis, realizing engagement or disengagement with the output gear 210. The sleeve design, which highly integrates the power input, motion conversion and clutch actuator, not only greatly compresses the radial and axial space of the components, making the entire drive component 200 compact, but also effectively avoids external interference through the embedded fit, ensuring that the guide part 261 and the sliding part 262 are in a stable fit during operation. At the same time, this integrated structure reduces the number of parts, simplifies the assembly process, and reduces production costs.

[0064] like Figure 5 and Figure 6 As shown, further, the transmission gear 230 is constructed with a base plate structure 232, the side of the base plate structure 232 facing the power gear 220 having an insert portion 231, and the side of the base plate structure 232 facing the output gear 210 having a first transmission tooth structure 233. The output gear 210 has a second transmission tooth structure 211 adapted to mesh with the first transmission tooth structure 233, and each tooth of the first transmission tooth structure 233 and the second transmission tooth structure 211 is configured in an axisymmetric structure.

[0065] In this embodiment, each tooth of the first transmission gear structure 233 and the second transmission gear structure 211 is designed as an axisymmetric structure. Understandably, when the drive source 240 drives the power gear 220 to rotate in the first or second direction, the axisymmetric structure can make the meshing process between the transmission gear 230 and the output gear 210 geometrically and mechanically symmetrical. This makes the contact stress, sliding friction conditions, and transmission load resistance characteristics of the gear pair when transmitting the winding driving force and performing the separation action more consistent. It avoids the difference in meshing performance and force state under forward and reverse working conditions caused by tooth asymmetry, thereby effectively avoiding the risk of premature tooth surface damage, pitting, or tooth breakage caused by unilateral wear, stress concentration, or uneven impact load during frequent reverse rotation meshing. This greatly improves the durability, operational stability, and long-term reliability of the entire mechanism in bidirectional working mode.

[0066] like Figure 9 As shown in the figure, in some embodiments, the elastic member 250 is configured as a cylindrical structure, and the transmission gear 230 is connected to one end of the elastic member 250. For example, the elastic member 250 is a cylindrical spring, a soft rubber part 251, etc. Compared with multiple circumferentially distributed elastic members, the cylindrical structure has better overall integrity, can apply a more uniform circumferential force to the transmission gear 230, and the cylindrical elastic member 250 can provide greater circumferential resistance to the transmission gear 230, so that the transmission gear 230 moves axially under the drive of the power gear 220, rather than rotating.

[0067] Furthermore, the elastic component 250 includes a soft rubber part 251, the peripheral sidewall of which is constructed with a folding structure 2511 that can be folded in the axial direction. The folding structure 2511 can guide the soft rubber part 251 to compress / unfold in a regular manner. For example, the folding structure 2511 includes wavy pleats or annular grooves and protrusions. The soft rubber part 251 has a good shock absorption effect, reducing operating noise. As a preset, repeatable deformation guide structure, the folding structure 2511 can guide the soft rubber part 251 to fold regularly along a predetermined path during compression and unfold orderly during rebound, reliably pushing the transmission gear 230 away from the output gear 210.

[0068] As shown in Figures 2 and 3, further, one axial end of the soft rubber part 251 is provided with an annular groove 2512, and the periphery of the transmission gear 230 extends into the annular groove 2512. More specifically, the transmission gear 230 is constructed with a base plate structure 232. The side of the base plate structure 232 facing the drive gear 220 is connected to the drive gear 220, and the side of the base plate structure 232 facing the output gear 210 is detachably connected to the output gear 210. The periphery of the base plate structure 232 is inserted into the annular groove 2512.

[0069] By interlocking the annular groove 2512 with the periphery of the transmission gear 230, a simple and effective connection between the soft rubber part 251 and the transmission gear 230 is achieved. The annular groove 2512 encloses and constrains the periphery of the transmission gear 230, which helps to improve the connection firmness between the two in multiple axial reciprocating movements and reduces the risk of relative displacement or loosening.

[0070] In some embodiments, the transmission gear 230 has a plurality of circumferentially spaced protrusions along its periphery. These protrusions are located within and abut against the annular groove 2512. The spaced protrusions ensure reliable connection between the transmission gear 230 and the soft rubber part 251, increase rotational friction between them, and thus ensure axial movement of the transmission gear 230.

[0071] In some embodiments, one of the output gear 210 and the drive gear 220 is located within the elastic member 250 and has a radial clearance between it and the inner peripheral wall of the elastic member 250. In this embodiment, the location of one of the output gear 210 and the drive gear 220 within the elastic member 250 achieves a compact component for the product. At the same time, the radial clearance reduces the rotational resistance of the output gear 210 or the drive gear 220, thereby reducing the driving force required by the drive source 240.

[0072] In some embodiments, a control device is also included, which is communicatively connected to the drive source 240. The control device is configured to control the drive source 240 to drive the power gear 220 to rotate in the second direction for a preset time based on a signal fed back by the detection device indicating that the wire is fully retracted.

[0073] When the winding action is detected or determined to be completed, the control device can actively control the drive source 240 to execute a brief reverse rotation program, driving the transmission gear 230 to disconnect the transmission connection with the output gear 210. This physically disconnects the meshing connection between the transmission gear 230 and the output gear 210. Thus, before the user performs the next manual dragging operation, the transmission separation has been completed in advance. Therefore, no matter when, at what speed, or with what force the user pulls the cable, the reel component 100 and the entire drive component 200 are in a defined mechanical decoupling state. The gear system resistance, motor magnetic reluctance, and other loads inside the drive source 240 are completely isolated, so that the resistance to be overcome when dragging the cable mainly comes from the small friction of the reel's own bearings, thus significantly saving effort.

[0074] Furthermore, it also includes a detection device that is communicatively connected to the control device. The detection device is suitable for detecting whether the wire has been properly stored and sending the detection result to the control device.

[0075] By adding a detection device that communicates with the control device and adapts it to detect the winding status of the wire, the actual winding position or winding completion of the wire can be monitored in real time. When the detection device (e.g., a position sensor, image sensor, or a counter based on the number of winding turns) obtains a definite signal indicating that the wire has been fully wound or has reached the predetermined winding position, the detection result is immediately sent to the control device. The control device then generates a control command based on this clear completion signal and drives the drive source 240 to rotate in the second direction for a preset time. This ensures that after any complete automatic winding operation, the disengagement state of the transmission gear 230 and the output gear 210 can be established in a timely and reliable manner, thereby creating a consistently low-resistance starting point for the user to manually pull the wire, ensuring the continuity and reliability of the labor-saving effect.

[0076] The present invention also provides a window air conditioner base station, comprising: a base station body and a cable storage device 10 as described in any of the foregoing embodiments, wherein the base station body is used for storing and / or cleaning the window air conditioner, and the cable storage device 10 is disposed on the base station body.

[0077] The present invention also provides a window unit system, including: a window unit, cables, and a window unit base station as described in any of the foregoing embodiments. The window unit is detachably disposed on the window unit base station. One end of the cables is connected to the cable reel component 100 of the cable storage device 10, and the other end is connected to the window unit.

[0078] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0079] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention.
