Description

Technical Field

[0001] This invention relates to the field of daily necessities technology, and in particular to a self-balancing roll-up air cushion umbrella. Background Technology

[0002] Umbrellas are essential everyday tools for providing shelter from rain and sun. Traditional umbrellas, in current technology, are typically handheld, requiring users to continuously grip the handle to support, unfold, and balance the canopy. This handheld design has inherent technical drawbacks: First, it occupies one hand, preventing users from freely using both hands while walking, exercising, or engaging in other activities, such as carrying items, operating equipment, or communicating, significantly reducing user experience and efficiency. Second, traditional umbrellas lack effective balance compensation mechanisms under external environmental disturbances (such as wind changes or user arm movements), making the canopy prone to tilting, flipping, or shaking, affecting the stability of sun or rain protection. Users must frequently manually adjust their posture to maintain balance, increasing operational burden and potentially leading to fatigue and safety hazards. Furthermore, the folding and unfolding of traditional umbrellas largely relies on manual operation, resulting in complex structures and large folded size, poor portability, and difficulty in achieving quick and compact folding.

[0050] The embodiments of the present invention have the following advantages due to the adoption of the above technical solutions:

[0051] This invention uses an arm-fixing component to stably fix the umbrella to the user's arm, eliminating the need for hand operation. This effectively solves the problem of traditional umbrellas requiring one or both hands and being inconvenient to carry, making it especially suitable for outdoor work, cycling, travel, and other scenarios.

[0052] This invention achieves automatic unfolding and resetting of the umbrella body from a folded state parallel to the arm to a vertical working state through the coordinated control of a self-balancing motor, a rotary motor, and a telescopic support rod. At the same time, by combining the winding mechanism, the air cushion for coordinated storage, and the linkage design of the rotating part, the storage volume is reduced, overcoming the shortcomings of traditional umbrellas that are cumbersome to store and bulky.

[0053] This invention provides rigid support for the outer edge of the umbrella fabric through the combination of an air cushion structure and fan inflation. Combined with an adjustment rod and spring, it provides real-time compensation for the tension of the umbrella fabric, effectively suppressing the shaking and deformation caused by wind. At the same time, the self-balancing motor generates a reverse compensation torque in real time according to environmental disturbances, so that the umbrella can remain vertical and stable in complex environments, solving the problems of traditional umbrellas being easily blown over by the wind and having poor stability.

[0054] This invention ensures uniform force and no twisting during the opening and closing of the umbrella by using a synchronous motor drive for the central and outer storage sections and a coaxial winding rod design. The air cushion and umbrella fabric are rolled up as a single unit, avoiding the cumbersome problems of separate air cushion structures and improving the overall integrity and reliability of the air cushion umbrella.

[0080] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of the invention. Therefore, the drawings and description are considered to be exemplary in nature and not restrictive.

[0081] It is important to note that terms such as "first," "second," "symmetric," and "array" are used only to distinguish between descriptive and positional descriptions and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, features specified with terms such as "first" or "symmetric" may explicitly or implicitly include one or more of that feature; similarly, when the quantity of certain features is not limited by words such as "two" or "three," it should be noted that such features also explicitly or implicitly include one or more features.

[0082] In this invention, unless otherwise explicitly specified and limited, terms such as "installation," "connection," and "fixation" should be interpreted broadly; for example, they can refer to a fixed connection, a detachable connection, or an integral molding; they can refer to a mechanical connection, a direct connection, a welding connection, or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the accompanying drawings and specific circumstances.

[0083] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0084] like Figure 1-14 As shown, an embodiment of the present invention provides a self-balancing roll-up air cushion umbrella, including...

[0085] Arm fixing component 1 is used to detachably wear on the user's arm so that the air cushion umbrella can be stably fixed on the user's arm, and to provide power to the air cushion umbrella and realize the operation control of the air cushion umbrella.

[0086] Specifically, the arm fixation assembly 1 includes:

[0087] The arm wrap 11 is wrapped around the user's arm, and its ends are secured with Velcro for adjustable fastening. The arm wrap 11 has a flexible strip structure with Velcro at the ends, allowing for a detachable connection between the air cushion umbrella and the user's arm. The Velcro provides adjustable fastening force to accommodate different user arm sizes, ensuring comfort and stability when worn.

[0088] The battery box 12 is fixedly installed on the outer side of the middle part of the arm wrap 11 to hold the power supply. The battery box 12 is located on the outer side of the arm wrap 11 to avoid the power supply from putting pressure on the arm and to achieve reasonable weight distribution, which is conducive to wearing balance.

[0089] The motherboard 13 with a casing is fixedly connected to one end of the battery box 12 and is used to integrate the control circuit to control the air cushion umbrella.

[0090] The unfolding mechanism unit has a self-balancing motor 2 fixedly connected to the arm fixing assembly 1, and a rotating extension assembly 3 connected to the output end of the self-balancing motor 2, for realizing the inflatable umbrella being inflated and maintaining its balance in the inflated state.

[0091] The self-balancing motor 2 is fixedly connected to the other end of the main board 13 with a shell. Its rotation axis is set perpendicular to the axis of the winding belt 11. The self-balancing motor 2 is electrically connected to the main board 13 with a shell.

[0092] When the air cushion umbrella is in use, the control of the self-balancing motor 2 by the main board 13 with the shell can generate a compensating torque in the opposite direction to the external disturbance torque (such as wind force or arm swing), thereby maintaining the balance of the umbrella body 5 when it is in the open state.

[0093] The rotating extension component 3 enables the transformation and support of the spatial pose of the umbrella body 5. The rotating extension component 3 includes:

[0094] The rotary motor 31 is connected to the output of the self-balancing motor 2. Its rotation axis is set perpendicular to the axis of the self-balancing motor 2. When in use, the rotary motor 31 can generate a compensating torque that is opposite to the direction of external disturbance torque (such as wind force or arm swing), and thus cooperate with the self-balancing motor 2 to keep the air cushion umbrella in a vertical sunshade state.

[0095] At the same time, it can be used to adjust the umbrella body 5 from a stored position parallel to the arm to a position where the support pole 32 is ready to be extended before opening the umbrella.

[0096] In this embodiment, both the self-balancing motor 2 and the rotary motor 31 are worm gear motors. Due to their self-locking properties, the air cushion umbrella can be firmly locked in the target position after the action is completed, resisting external interference and maintaining the vertical balance of the umbrella.

[0097] One end of the strut part 32 is connected to the output shaft of the rotary motor 31;

[0098] The support pole 32 allows for adjustment of the unfolding height of the umbrella body 5, including:

[0099] The telescopic inner rod 321 is rotatably connected to the output shaft of the rotary motor 31 at its bottom end. Guide bars 322 are symmetrically provided on both sides of the telescopic inner rod 321 along its length direction. The guide bars 322 cooperate with the guide grooves 327 in the telescopic outer rod 326 to prevent relative rotation between the telescopic outer rod 326 and the telescopic inner rod 321, so that it can only move along the axial direction.

[0100] In this embodiment, one of the guide bars 322 is located on the upper part of the telescopic inner rod 321 and cooperates with the rotating part 33.

[0101] The telescopic motor 323 is coaxially mounted at the bottom of the telescopic inner rod 321, serving as the power source for the telescopic movement and providing rotational motion and torque;

[0102] The telescopic rotor 324 is rotatably mounted on the top of the telescopic inner rod 321 and is coaxially mounted with the telescopic inner rod 321;

[0103] The connecting shaft 325 is coaxially arranged inside the telescopic inner rod 321. One end of the connecting shaft 325 is connected to the output shaft of the telescopic motor 323, and the other end is connected to the telescopic rotor 324.

[0104] The telescopic outer rod 326 is sleeved outside the telescopic inner rod 321 and threadedly connected to the telescopic rotor 324. The telescopic outer rod 326 is provided with a guide groove 327 that cooperates with the guide strip 322.

[0105] The telescopic motor 323 serves as the power source, transmitting rotational motion to the telescopic rotor 324 via the connecting shaft 325. Since the telescopic outer rod 326 is sleeved outside the telescopic inner rod 321, the internal thread of the telescopic outer rod 326 and the telescopic rotor 324 form a screw-nut mechanism. Simultaneously, with the cooperation of the guide groove 327 and the guide rail 322, mutual rotation between the telescopic outer rod 326 and the telescopic inner rod 321 is prevented. Thus, the rotational motion of the telescopic rotor 324 is converted into the linear telescopic motion of the telescopic outer rod 326, realizing the extension and retraction of the support rod 32.

[0106] The rotating part 33 is provided at the top of the support rod part 32 and is connected to the storage mechanism 4. It is used to make the umbrella unit flip vertically when the support rod part 32 is extended, and to keep the umbrella unit parallel to the arm when the support rod part 32 is retracted.

[0107] The rotating part 33 includes:

[0108] The slide bar 331 is slidably disposed on one side of the outside of the telescopic outer rod 326, and its sliding direction is parallel to the axis of the telescopic outer rod 326.

[0109] In practice, the sliding rod 331 is positioned to correspond to the guide bar 322 located on the upper part of the telescopic inner rod 321, and its lower end can cooperate with the guide bar 322.

[0110] The limiting cylinder 332 is coaxially mounted on the top of the telescopic outer rod 326. It has a sliding cavity inside and a long sliding opening 333 for the upper end of the sliding rod 331 to pass through. The long sliding opening 333 allows the upper end of the sliding rod 331 to pass through and can move up and down along the long sliding opening 333. At the same time, the length of the long sliding opening 333 is the maximum stroke of the sliding rod 331, preventing the slider 334 from sliding out of the limiting cylinder 332.

[0111] The slider 334 is slidably disposed in the slide cavity, and its lower part is fixedly connected to the upper end of the slide rod 331.

[0112] During implementation, when the upper end of the slide rod 331 slides to the upper end of the long slide opening 333, the upper part of the slider 334 is located above the limiting cylinder 332. At this time, the bottom end of the slide rod 331 abuts against the corresponding guide bar 322.

[0113] The rotating block 335 is rotatably connected to the slider 334, and its upper end is fixedly connected to the storage mechanism 4. The rotating block 335 can be slidably connected to the limiting cylinder 332.

[0114] In the initial state, the rotating block 335 is located outside the limiting cylinder 332. At this time, the top of the slide rod 331 is located at the top of the long slide opening 333, and the storage mechanism 4 and the support rod part 32 are in a parallel and fitted state.

[0115] When the support rod 32 extends, the telescopic outer rod 326 and the telescopic inner rod 321 move relative to each other. When the guide strip 322 on the telescopic inner rod 321, which cooperates with the slide rod 331, slides out of the telescopic outer rod 326, it abuts against the bottom end of the slide rod 331, causing the slide rod 331 to move downward. This causes the slider 334 to move downward in the sliding cavity of the limiting cylinder 332. Due to the rotational connection between the slider 334 and the rotating block 335, the rotating block 335 rotates around the hinge point between itself and the slider 334. This allows the rotating block 335 to enter the limiting cylinder 332 under the downward movement of the slide rod 331, thereby causing the storage mechanism 4 to flip from a position parallel to the support rod 32 to a position perpendicular to the support rod 32 (i.e., vertical).

[0116] The umbrella unit has a storage mechanism 4 connected to the rotating extension assembly 3, and an umbrella body 5 connected to the storage mechanism 4. The storage mechanism 4 is used to control the umbrella body 5 so as to achieve controllable deployment, stable support and storage of the umbrella body 5.

[0117] Storage unit 4 includes:

[0118] The central storage section 41 is connected to the umbrella body section 5, and one end of it is located at the center of the umbrella body section 5.

[0119] The outer storage part 42 is rotatably connected to the central storage part 41 and is connected to the outer area of ​​the umbrella body part 5;

[0120] The storage motor 43 is mounted on the central storage part 41 and connected to the outer storage part 42 via a pin. It is used to drive the outer storage part 42 to rotate relative to the central storage part 41 so as to realize the unfolding and storage of the umbrella body.

[0121] When stored, the storage motor 43 drives the outer storage part 42 to rotate and move closer to the central storage part 41, reducing the volume of the umbrella unit in the stored state so that it can fit tightly against the user's arm.

[0122] The central storage unit 41 includes:

[0123] The storage shell 411 has a storage cavity 412 inside, and a first motor 413 is installed in the storage cavity 412. Its rotation axis is arranged parallel to the extension direction of the storage shell 411.

[0124] The winding rod 414 is connected to the output shaft of the first motor 413;

[0125] The central area of ​​the umbrella body 5 is fixedly connected to the winding rod 414. When the first motor 413 rotates forward and backward, it drives the winding rod 414 to wind up or release the umbrella body 5.

[0126] The top cover 415 is connected to the upper end of the storage shell 411 and forms a space between it and the storage shell 411 for installing part of the umbrella body 5. It provides an orderly receiving cavity for the rolled-up umbrella body 5 and plays a role in organizing and guiding the movement of the umbrella body 5, preventing it from becoming disordered, tangled or stuck during the winding operation, and ensuring the reliability and repeatability of the storage process.

[0127] A waterproof gasket 416 is installed on the top cover 415 and is coaxially arranged with the umbrella body 5. When the umbrella body 5 is opened, the waterproof gasket 416 fills the gap between the top cover 415 and the umbrella body 5, effectively preventing rainwater from seeping into the internal storage cavity 412 from the central opening of the top cover 415, thereby improving the waterproof performance and reliability of the product.

[0128] A fixing ring 417 is adhered to the umbrella body 5 and coaxially disposed inside the waterproof gasket 416. In this embodiment, the fixing ring 417 is made of rubber. When the umbrella body 5 is folded up, the fixing ring 417 can enter the storage shell 411 along with the umbrella body 5. When the umbrella body 5 is in the unfolded state, the fixing ring 417 is coaxially located inside the waterproof gasket 416, ensuring that the center point of the umbrella body 5 is fixed when unfolded, while the surrounding area is stretched evenly, thereby forming a flat sunshade surface.

[0129] The outer storage section 42 includes:

[0130] Storage shell 2 421 has the same structure as storage shell 1 411, and has storage cavity 2 422 inside;

[0131] The storage cavity 422 is equipped with a second motor 423, whose rotation axis is coaxial with the rotation axis of the first motor 413.

[0132] The second winding rod 424 is connected to the output shaft of the second motor 423;

[0133] The second motor 423 and the second retractor 424 drive the opening and closing of the outer area of ​​the umbrella body 5. The coaxial design of the second motor 423 and the first motor 413 ensures that the second motor 423 and the first motor 413 move synchronously and are subjected to uniform force when driving the umbrella body 5 in their respective areas, so as to achieve flat umbrella surface and twist-free opening and closing.

[0134] The upper cover 425 is connected to the upper end of the storage shell 421 and forms a space for installing part of the umbrella body 5 between the upper cover 425 and the storage shell 421. The upper cover 425 and the storage shell 421 together form a space for installing part of the umbrella body 5, providing an orderly receiving cavity for the rolled-up umbrella body 5, and playing a role in organizing and guiding the movement of the umbrella body 5, preventing it from becoming disordered, tangled or stuck during the winding operation, and ensuring the reliability and repeatability of the storage process.

[0135] The adjusting rod 426 is slidably disposed at the bottom of the second upper cover 425, and its sliding direction is the same as the extending direction of the second upper cover 425. The adjusting rod 426 is connected to the umbrella body 5.

[0136] Spring 427, connected between adjusting rod 426 and upper cover 425, is used to provide elastic adjusting force;

[0137] In practice, by setting the adjusting rod 426 and the spring 427, while ensuring the normal opening and closing of the umbrella body 5, potential interference caused by the folding movement between the central storage part 41 and the outer storage part 42 can be avoided, and the continuous tension of the umbrella body 5 can be maintained.

[0138] Specifically, when the storage cavity 2 422 rotates and folds relative to the storage shell 1 411, the straight-line distance between the storage cavity 2 422 and the storage shell 1 411 shortens, causing the umbrella body 5 connected between the two to be stretched. At this time, the adjusting rod 426, pulled by the umbrella body 5, overcomes the elastic force of the spring 427 and slides towards the central storage part 41. When the compression of the spring 427 is greater than the maximum stretch of the umbrella body 5, the spring 427 returns to its original position, driving the adjusting rod 426 to reset. This automatically compensates for the excess stretch of the umbrella body 5, effectively preventing the umbrella body 5 from bearing excessive and destructive tensile stress due to the folding motion of the storage mechanism 4.

[0139] Meanwhile, to prevent the fixed end of the umbrella body 5 from being stretched when the first storage shell 411 and the second storage cavity 422 are rotated and folded, symmetrical arc-shaped grooves are provided at the hinge of the first cover 415 and the second cover 425. This provides additional space for the umbrella body 5 to move, preventing possible squeezing, friction, or interference at the hinge of the first storage shell 411 and the second storage cavity 422. Furthermore, it prevents the central fixing point of the umbrella body 5 from shifting due to lateral tension, ensuring the stability and reliability of the connection in the central area of ​​the umbrella body 5.

[0140] In addition, after the umbrella body 5 is fully deployed, the spring force of the spring 427 continues to act on the umbrella body 5 through the adjusting rod 426, automatically compensating for the slack caused by material expansion or structural deformation, and ensuring that the umbrella body 5 is always in a tight and flat ideal working state.

[0141] Ventilation duct 428 is provided at the end of the upper cover 425 and is connected to the umbrella body 5;

[0142] A fan 429 is disposed within a ventilation duct 428; when driven to rotate, the fan 429 pushes air to generate a directional airflow from the inlet to the outlet within the ventilation duct 428, thereby providing the aerodynamics required for the inflation of the air cushion 52.

[0143] A ball-core motor 430 is mounted on the upper cover 425 and works in conjunction with the ventilation duct 428 to control the shut-off of the ventilation duct 428.

[0144] In practice, the ventilation duct 428 serves as an airflow delivery channel, which can guide the airflow generated by the fan 429 to the umbrella body 5.

[0145] The umbrella body 5 includes:

[0146] The umbrella fabric 51 unfolds into a circular structure, with an opening on one side extending radially to the center. The central area of ​​the umbrella fabric 51 is fixedly connected to the top cover 415. The umbrella fabric 51 is attached to the waterproof gasket 416 and bonded to the fixing ring 417. The umbrella fabric 51 extends into the storage shell 411 and the storage shell 421 on one side of the opening and is fixedly connected to the corresponding roller rod 414 and the roller rod 424 respectively. On the other side of the opening, the umbrella fabric 51 is fixedly connected to the storage shell 411 at the position corresponding to the roller rod 414 and to the adjusting rod 426 at the position corresponding to the roller rod 424.

[0147] In practice, one side of the opening of the umbrella fabric 51 is fixed to the first roller 414 and the second roller 424 respectively. When the first motor 413 and the second motor 423 drive the first roller 414 and the second roller 424 to rotate synchronously, the umbrella fabric 51 can be opened and closed.

[0148] Air cushion 52 is a flexible sealing airbag, which is arranged circumferentially along the outer edge of umbrella fabric 51. One end of it is fixedly connected to adjustment rod 426 and connected to ventilation duct 428, and the other end extends into storage shell 421 and is fixedly connected to the corresponding position of roll rod 424.

[0149] The air cushion 52 is fixedly connected to the adjusting rod 426 to ensure synchronous movement of the air cushion 52 and the tension side of the umbrella fabric 51. It is connected to the ventilation duct 428 and can receive airflow from the fan 429 to inflate the air cushion 52.

[0150] Meanwhile, the other end of the air cushion 52 is fixedly connected to the second roll rod 424, so that when storing the umbrella fabric 51, the air cushion 52 can be rolled into the second storage shell 421 at the same time, realizing the coordinated storage of the air cushion 52 and the umbrella fabric 51, avoiding mutual interference and ensuring the compactness of storage.

[0151] During implementation, after the air cushion 52 is inflated, it forms a support frame with a certain rigidity, which provides support for the outer edge of the soft umbrella fabric 51 and maintains the unfolded shape of the umbrella surface.

[0152] Meanwhile, the air cushion 52 has a certain weight and elasticity, which can suppress the impact of wind to a certain extent, reduce the shaking and flipping of the umbrella surface, and improve its wind resistance performance.

[0153] Moreover, its ring structure helps to lower the center of gravity of the entire umbrella, which plays a role in maintaining its balance.

[0154] In specific implementation of this invention:

[0155] 1) Wearing and securing:

[0156] The user wears the device on their arm using the arm fixation component 1:

[0157] The arm wrap 11 is wrapped around the arm and the tightness is adjusted with Velcro to fit different arm sizes, ensuring a secure and comfortable fit.

[0158] The battery box 12 is located on the outside of the arm wrap, and its built-in power supply powers the air cushion umbrella, avoiding pressure on the arm.

[0159] The motherboard with casing 13 integrates control circuitry, outputs control commands, and coordinates the operation of each motor.

[0160] 2) Umbrella deployment and attitude adjustment:

[0161] 2.1 Initial state:

[0162] The umbrella body 5 is in a stowed state, and the stowage mechanism 4 is parallel to the user's arm and fits snugly against the user's arm, with a compact size.

[0163] 2.2 Rotation and unfolding:

[0164] After the user triggers the switch, the self-balancing motor 2 starts, and at the same time the rotary motor 31 starts. Through the cooperation of the self-balancing motor 2 and the rotary motor 31, the support pole 32 is rotated from the retracted state parallel to the arm to the extended posture. After the action is completed, the umbrella body can be firmly locked in the target position to resist external interference and maintain the vertical balance of the umbrella body.

[0165] 2.3 Strut extension and retraction:

[0166] When the telescopic motor 323 starts, it drives the telescopic rotor 324 to rotate through the connecting shaft 325. The telescopic rotor 324 and the internal threads of the telescopic outer rod 326 form a screw and nut pair. Under the constraint of the guide bar 322 and the guide groove 327, the telescopic outer rod 326 extends along the axial direction, pushing the umbrella body 5 to rise.

[0167] 2.4 Umbrella body flipping:

[0168] When the support rod 32 extends to a certain position, the guide bar 322 on the upper part of the telescopic inner rod 321 contacts the bottom end of the slide rod 331, pushing the slide rod 331 to slide downward.

[0169] The slide bar 331 moves down along the long slide opening 333 of the limiting cylinder 332 under the push of the guide bar 322, thereby driving the slider 334 to move down inside the limiting cylinder 332, causing the rotating block 335 to rotate around the hinge point and enter the limiting cylinder 332, so that the storage mechanism 4 flips from the posture parallel to the support rod part 32 to the vertical state (i.e. the umbrella body unfolds vertically).

[0170] 3) Umbrella fabric 51 unfolds and air cushion 52 inflates:

[0171] 3.1 Umbrella fabric unfolded:

[0172] The storage motor 43 drives the outer storage part 42 to rotate and unfold relative to the central storage part 41, so that the storage mechanism 4 unfolds linearly.

[0173] The first motor 413 and the second motor 423 rotate slowly and synchronously, releasing the umbrella fabric 51 wound on the first winding rod 414 and the second winding rod 424, so as to facilitate the smooth opening of the umbrella fabric 51 when the air cushion 52 is inflated, and to avoid obstruction during the opening operation.

[0174] 3.2 Air cushion inflation and tension adjustment:

[0175] When the fan 429 is activated, it pumps air into the air cushion 52 through the ventilation duct 428, inflating it to form the umbrella fabric 51 and providing rigid support for the outer edge of the umbrella fabric 51. The ball-core motor 430 can close the ventilation duct 428.

[0176] Adjusting rod 426 automatically adjusts the umbrella fabric tension under the action of spring 427:

[0177] If the umbrella fabric 51 is stretched due to folding or wind, the adjusting rod 426 slides to compress the spring 427 to avoid excessive stress; after unfolding, the spring force of the spring 427 continues to act, keeping the umbrella fabric 51 in a taut state.

[0178] Waterproof gasket 416 and retaining ring 417 ensure that the center of the umbrella is sealed and secured, preventing rainwater from seeping in.

[0179] 4) Self-balancing and wind resistance adjustment:

[0180] After the umbrella fabric 51 is unfolded, the main board 13 with the shell monitors environmental disturbances (such as wind force and arm swing) in real time, and generates a compensating torque opposite to the direction of the external torque through the cooperation of the self-balancing motor 2 and the rotary motor 31 to maintain the umbrella body vertical.

[0181] For example, if the wind tries to knock over the umbrella, the self-balancing motor 2 and the rotary motor 31 work together to drive the support rod 32 to make a slight adjustment in the opposite direction, thus counteracting the overturning moment.

[0182] When inflated, the Air Cushion 52 has elasticity and weight, which can absorb wind vibration energy, reduce umbrella surface shaking, and enhance stability.

[0183] 5) Umbrella storage and repositioning:

[0184] Umbrella roll-up:

[0185] The ball-core motor 430 can open the ventilation duct 428. The first motor 413 and the second motor 423 rotate synchronously in opposite directions to roll up the umbrella fabric 51. The air cushion 52 is synchronously retracted into the storage shell along with the umbrella fabric 51. At the same time, the air in the air cushion 52 is discharged through the ventilation duct 428, achieving the effect of exhausting and closing the umbrella.

[0186] The adjusting rod 426, under the action of the spring 427, compensates for the stretching changes of the umbrella fabric 51 during the winding process, preventing excessive stretching.

[0187] The storage motor 43 drives the outer storage section 42 to rotate and fold towards the central storage section 41.

[0188] The telescopic motor 323 reverses, retracting the support rod 32. During retraction, the slide rod 331 separates from the corresponding guide bar 322 and can move along the axial direction of the telescopic outer rod 326. At the same time, under the gravity of the storage mechanism 4 and the umbrella body 5, the rotating block 335 gradually slides out of the limiting cylinder 332 and rotates around the hinge point with the movable slider 334, causing the umbrella unit to flip from a vertical posture back to a posture parallel to the support rod 32.

[0189] Finally, the rotating motor 31 reverses its direction, rotating the umbrella unit back to its stowed position that fits the arm.

[0190] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in the present invention, and these should all be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
