[0022] Reference Figures 1 to 13A folding umbrella includes: an umbrella base 100, an umbrella body 200, and a folding drive device 300. The umbrella base 100 is provided with an umbrella column portion 110, and the umbrella column portion 110 is provided with a column cavity 111 extending along the length direction of the umbrella column portion 110. One end of the column cavity 111 along the length direction is provided with an inlet / outlet opening 1111. The length direction of the umbrella column portion 110 is defined as the up-down direction, and the side of the umbrella column portion 110 with the inlet / outlet opening 1111 is defined as the upper side. The umbrella body 200 includes a central rod 210, an umbrella support rod 220, and an umbrella surface 230. The central rod 210 is movably disposed in the column cavity 111 and can move along the column cavity 111. Multiple umbrella support rods 220 are provided, one end of which is hinged to the central rod 210. The umbrella support rods 220 are arranged circumferentially along the central rod 210. The umbrella surface 230 is connected to the umbrella support rods 220. The umbrella support rods 220 can be folded together and opened relative to the central rod 210. When the umbrella support rods 220 are folded, the umbrella body 200 can be retracted downward into the column cavity 111 through the inlet / outlet opening 1111 and can be extended upward out of the column cavity 111 through the inlet / outlet opening 1111. When the umbrella body 200 is extended out of the column cavity 111, the umbrella support rods 220 can be opened and the umbrella surface 230 can be spread out. The folding drive device 300 is disposed on the umbrella column 110 and cooperates with the umbrella body 200. The folding drive device 300 is used to control the umbrella support rod 220 to close and cause the umbrella body 200 to be retracted into the column cavity 111, and to cause the umbrella body 200 to extend out of the column cavity 111 and control the umbrella support rod 220 to open.

[0023] When folding, the umbrella support rods 220 can be retracted together by the folding drive device 300, allowing the umbrella body 200 to be fully retracted into the column cavity 111 of the umbrella column 110. When the folding umbrella needs to be opened for use, the umbrella body 200 is extended out of the column cavity 111 by the folding drive device 300 again, and the umbrella support rods 220 are opened, allowing the umbrella surface 230 to be opened for use. The aforementioned folding umbrella allows the umbrella body 200 to be stored in the column cavity 111 when folded, resulting in a neat and simple overall structure after storage, and providing better protection for the umbrella surface 230 and the umbrella support rods 220. The folding and opening of the umbrella body 200, as well as its retraction and extension into and out of the column cavity 111, are all controlled uniformly by the folding drive device 300, making operation convenient and simple.

[0024] In this embodiment, the folding drive device 300 includes a moving drive assembly 310 and a linkage mechanism 320. The moving drive assembly 310 is movably disposed on the umbrella column portion 110 and can move along the length direction of the umbrella column portion 110. The moving drive assembly 310 is connected to the central rod 210 and can drive it to move. The moving drive assembly 310 is movably disposed with an operating member 311. The operating member 311 and the umbrella support rod 220 cooperate with each other through the linkage mechanism 320. When the operating member 311 moves, the linkage mechanism 320 can control the umbrella support rod 220 to fold and open. When folding, the individual umbrella support rods 220 can be retracted first by controlling the operating component 311, and then the entire moving drive assembly 310 is pulled. The moving drive assembly 310 pulls the central rod 210 to move, causing the umbrella body 200 to be retracted into the column cavity 111, thus achieving folding and storage. When the folded umbrella needs to be opened for use, the umbrella support rods 220 can be reopened by controlling the operating component 311, and then the entire moving drive assembly 310 is pulled back to extend the umbrella body 200 out of the column cavity 111. After the umbrella support rods 220 are opened, it can be used. The above structure simply realizes the structural function of the folding drive device 300, is easy to implement, and is convenient to operate.

[0025] In this embodiment, the umbrella support rod 220 is configured to rotate upwards to close and downwards to open. With this structure, the umbrella support rod 220 is configured to rotate upwards to close, which, compared to rotating downwards to close, avoids the central rod 210 being too long and avoids the need for the umbrella support rod 220 to extend upwards sufficiently to avoid the umbrella column 110 during folding, thus making the overall structure of the folding umbrella more compact.

[0026] In this embodiment, when the umbrella support rod 220 is opened, the upper end of the umbrella column portion 110 abuts against and limits the umbrella support rod 220. The upper end of the umbrella column portion 110 can limit the umbrella support rod 220, thereby ensuring structural stability when the umbrella support rod 220 is opened. Using the upper end of the umbrella column portion 110 to limit the umbrella support rod 220 and keep it in the open state also simplifies the structure of the folding umbrella.

[0027] It is conceivable that in other embodiments, the umbrella support rod 220 may also adopt a structure that rotates downwards to fold and upwards to open. The folding drive device 300 can be adapted to the above structure. Both of these folding and opening methods are within the protection scope of this utility model. In the embodiments, the folding drive device 300 is not limited to the structure disclosed in this embodiment, and can be implemented using existing suitable structures as needed.

[0028] In this embodiment, the end of the column cavity 111 with the inlet / outlet opening 1111 is configured as a conical flared structure, and the wall surface of the conical flared structure is a conical guide surface. When each umbrella support rod 220 is opened, it can be driven by the operating member 311 and the linkage mechanism 320 to rotate in the closing direction by a pre-closing angle. The pre-closing angle is an acute angle. The conical guide surface is used to guide each umbrella support rod 220 to further close together when it closes the pre-closing angle and moves downward, so that each umbrella support rod 220 can be retracted into the column cavity 111. With the above structure, during the folding operation, the operating component 311 does not need to completely fold the umbrella support rods 220 to a vertical position when driving them to close. Instead, it pre-folds them at an acute angle. Then, during the pulling of the moving drive assembly 310, the tapered guide surface of the tapered flared structure guides the umbrella support rods 220 to further close, ultimately retracting them into the column cavity 111. This structure avoids requiring the operating component 311 to drive the umbrella support rods 220 to perform large-scale movements, reducing the difficulty of operation.

[0029] It is conceivable that in other embodiments, the operating member 311 can also drive the individual umbrella support rods 220 to fully retract, or the inlet and outlet openings 1111 of the column cavity 111 are large enough that the conical flare structure may not be necessary.

[0030] In this embodiment, the linkage mechanism 320 includes a linkage disc 321, a resetter 322, and a pull rod assembly 323. One end of the umbrella support rod 220, which is hinged to the central rod 210, extends outward toward the centerline of the central rod 210 with a linkage end 221. The linkage disc 321 is movably mounted relative to the central rod 210. The linkage disc 321 cooperates with the linkage ends 221 of each umbrella support rod 220 and is used to press down the linkage ends 221. The resetter 322 is mounted on the central rod 210 and is used to reset the linkage disc 321 upward. The operating member 311 cooperates with the linkage disc 321 through the pull rod assembly 323. When the operating member 311 moves, it can pull the linkage disc 321 downward through the pull rod assembly 323 and can release the pull rod assembly 323 to allow the linkage disc 321 to be reset by the resetter 322. When the umbrella is folded, the operating element 311 drives the pull rod assembly 323 to pull the linkage plate 321 downward, causing the linkage end 221 to move downward, and the umbrella support rod 220 can then rotate upward to close. When the umbrella needs to be opened, the operating element 311 releases the pull rod assembly 323. After the closed umbrella support rod 220 extends from the column cavity 111, the reset device 322 causes the linkage plate 321 to return to its original position. The umbrella support rods 220 can then rotate under the combined action of gravity and the reset device 322 to reopen. The linkage mechanism 320 adopts the above structure, which is simple and easy to implement.

[0031] In this embodiment, the resetter 322 can be a gas spring, a hydraulic cylinder, or a spring structure, and the specific configuration can be determined according to the actual situation. In this embodiment, the resetter 322 is fixed to the central rod 210, and the linkage disc 321 can be fixed to the telescopic end of the resetter 322, so that it can move relative to the central rod 210.

[0032] In some embodiments, the linkage end 221 can be linked to the linkage disk 321. For example, by providing a hinge strip hole in the linkage end 221, the linkage disk 321 can be hinged to the hinge strip hole by providing a hinge shaft; or the linkage end 221 can be hinged to the linkage disk 321 via another connecting rod, thereby forming a linkage mechanism to achieve the linkage between the two. In other embodiments, the linkage disk 321 can also be linked to the linkage end 221 by a pressing fit, that is, when the linkage disk 321 moves downward, it directly presses against the linkage end 221, and the umbrella support rod 220 can be unfolded by gravity or an additional reset structure after the linkage disk 321 is reset.

[0033] In this embodiment, the operating component 311 is a rotary handle connected to a rotating shaft 312. The rotating shaft 312 is equipped with a cam 313. The upper end of the pull rod assembly 323 is fixed to the linkage plate 321, and the lower end is equipped with a receiving plate 3231. The cam 313 is located on the upper side of the receiving plate 3231, and the circumferential surface of the cam 313 abuts against the receiving plate 3231. When the driving operating component 311 rotates, it can drive the cam 313 to rotate. The cam 313 can press against and move the receiving plate 3231. When the cam 313 presses against the receiving plate 3231, it can pull the pull rod assembly 323 downward, thereby driving the linkage plate 321 to press down. When the cam 313 moves away from the receiving plate 3231, the linkage plate 321 can be reset by the resetter 322, thereby driving the pull rod assembly 323 to reset. The above structure is simple, easy to implement, and labor-saving to operate; in addition, the operating component 311 is a rotary handle, which can also be used as a grip to pull the entire moving drive assembly 310, thus facilitating operation.

[0034] In one embodiment, a clearance opening is provided on the circumferential surface of the umbrella column 110 along its length. The movement drive assembly 310 passes through this clearance opening, thereby allowing it to move along the length of the umbrella column 110. In another embodiment, a rotating shaft 312 passes through and is connected to the central rod 210, so that the movement drive assembly 310 can drive the central rod 210 to move synchronously.

[0035] It is conceivable that the operating element 311 is not limited to a rotary handle structure. For example, the operating element 311 could also be a pull handle, which is connected to the lever assembly 323 to drive the lever assembly 323 to move up and down. It is understood that there are many implementations in the art of driving one component to move another component in a predetermined direction, and those skilled in the art can configure it according to the actual situation.

[0036] In this embodiment, guide rails 112 are respectively provided on the two opposite inner walls of the umbrella column 110. The guide rails 112 extend along the length of the umbrella column 110. Roller assemblies are respectively provided on both sides of the central rod 210 corresponding to the two guide rails 112. The roller assembly includes multiple rollers 211 arranged in the vertical direction. The circumferential surface of the rollers 211 is provided with annular grooves, and the rollers 211 cooperate with the corresponding guide rails 112 through the annular grooves. With the above structure, the movement of the central rod 210 is smooth and stable.

[0037] It is conceivable that the central rod 210 is not limited to being movably set in the column cavity 111 using the above-described structure. For example, the central rod 210 can also be directly slidably connected to the column cavity 111.

[0038] In this embodiment, a dust cover 400 is also included. The dust cover 400 is adapted to the upper end of the umbrella column portion 110. The dust cover 400 is used to seal the inlet and outlet opening 1111 after the umbrella body 200 is retracted into the column cavity 111. With the above structure, the umbrella can be better protected in the folded state.

[0039] In this embodiment, a lighting unit 115 is provided at the upper end of the umbrella column 110, and a support foot 120 is connected to the lower end of the umbrella column 110. With the above structure, the folding umbrella can also be used as a garden light, offering multiple functions. Of course, it is conceivable that the structure of the folding umbrella in this embodiment is not limited to its application in the field of garden lights; it can be applied to other types of umbrellas as needed.

[0040] In this embodiment, the folding umbrella also includes a solar panel 500, a battery, and a control board. The solar panel 500 is disposed on the upper surface of the umbrella column 110, which is equipped with a battery box 600. The battery and control board are disposed in the battery box 600. The solar panel 500 is used to charge the battery. The lighting unit 115 includes a lampshade and a light source board disposed within the lampshade. The battery is used to power the light source board and the control board. The control board is electrically connected to the light source board. The control board is equipped with a light switch 700, a power display structure 800, and a charging interface 900. The charging interface 900 is used to connect a charging cable for charging the battery. The light switch 700, the power display structure 800, and the charging interface 900 are exposed relative to the umbrella column 110. With the above structure, the folding umbrella, when used as a garden light, has more complete and richer functions.

[0041] In one embodiment, the power display structure 800 is a group of linearly arranged LEDs, and the number of LEDs lit corresponds to the power level. In other embodiments, the power display structure 800 is not limited to the above structure; for example, a display screen can be used to display the power level.

[0042] In one embodiment, the charging interface 900 is a TYPE-C interface, or in other embodiments, other suitable interfaces, such as a DC interface, may be used.

[0043] 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.

[0044] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model 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 the present utility model.
