Description

Technical Field

[0001] This utility model belongs to the field of outdoor sunshade technology, specifically relating to a sunshade umbrella with an inward-shrinking canopy structure. Background Technology

[0002] Outdoor sun umbrellas are large outdoor umbrellas used to protect people from wind and rain. Existing outdoor sun umbrellas typically have the canopy located on the outside of the umbrella post when closed, such as Roman umbrellas or banana umbrellas. When closed, the canopy is positioned on one side of the post and hangs vertically downwards, taking up considerable space. This also increases the risk of collisions with people or furniture under the umbrella, potentially causing danger. Current technology also includes sun umbrellas like the flat umbrella, where the canopy opens or closes at the top of the post. While this avoids the space-consuming problem to some extent, the canopy is still exposed to the open air when closed, easily accumulating dust and dirt over time. Furthermore, sunlight, rain, and wind can affect the lifespan of the canopy.

[0003] Therefore, as disclosed in announcement number CN118000513A, a sun umbrella with a retractable canopy is provided. The umbrella includes a pillar, an umbrella frame mounted on the pillar, a retraction control mechanism, and a canopy arranged on the frame. The retraction control mechanism controls the opening and closing of the sun umbrella. The mechanism includes umbrella cords, with the center of the canopy connected to the inner cavity of the pillar, and the upper end of the cords connected to the canopy. The retraction control mechanism can retract the canopy into the inner cavity of the pillar by extending and retracting the cords. This invention utilizes the cords of the retraction control mechanism to retract the canopy into the inner cavity of the pillar, preventing the canopy from being exposed and extending its lifespan. Furthermore, the sun umbrella has a more novel appearance when closed.

[0004] However, while the parasol with the above-mentioned structure can store the canopy, it cannot close the ribs internally, leaving the ribs exposed, which is a limitation. Utility Model Content

[0005] To address the aforementioned issues, this utility model aims to provide a sunshade umbrella with an inward-retracting canopy structure. The canopy can be stored inside the umbrella poles, greatly saving space. The closing process is simple and convenient, and the umbrella rib structure is optimized so that the umbrella ribs will not collide with the user when the canopy is opened or closed, thus improving the user experience.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0031] Combined with appendix Figures 1 to 11 As shown, this embodiment discloses a sunshade umbrella with a retractable canopy structure, including an umbrella frame assembly 1 and an umbrella column 2. A base 3 is provided inside the umbrella column 2. The umbrella frame assembly 1 and the base 3 are installed together. The base 3 is installed together with a lifting drive mechanism 4. The lifting drive mechanism 4 can drive the base 3 to move up and down along the umbrella column 2, and simultaneously drive the umbrella frame assembly 1 to retract into the inner cavity of the umbrella column 2 or extend upward. When the lifting drive mechanism 4 drives the base 3 to the upper umbrella opening position of the umbrella column 2, the umbrella frame assembly 1 is in a retracted state and extends upward. An umbrella opening mechanism 30 is also provided inside the base 3. The lifting drive mechanism 4 can drive the umbrella opening mechanism 30 to realize the unfolding of the umbrella frame assembly 1.

[0032] In conjunction with the above, the umbrella frame assembly 1 includes an upper umbrella plate 12, a lower umbrella plate 14, a plurality of long umbrella ribs 11 and a plurality of short umbrella ribs 13. One end of the long umbrella ribs 11 is hinged to the lower umbrella plate 14 and the other end extends outward. One end of the short umbrella ribs 13 is hinged to the upper umbrella plate 12 and the other end is hinged to the long umbrella ribs 11.

[0033] In this embodiment, based on the above installation structure, the upper umbrella plate 12 and the lower umbrella plate 14 are provided with a plurality of mounting grooves in the circumferential direction. The end of the long umbrella rib 11 is inserted into the mounting groove and then hinged to the lower umbrella plate 14. A hinge seat is provided on the upper part of the long umbrella rib 11. One end of the short umbrella rib 13 is inserted into the mounting groove and then hinged to the upper umbrella plate 12, and the other end is hinged to the long umbrella rib 11 through the hinge seat. In addition, an umbrella cloth is also provided on the outside of the long umbrella rib 11.

[0034] In combination with the above installation structure, preferably, in this embodiment, the short umbrella rib 13 and the upper umbrella plate 12 are located on the upper part of the long umbrella rib 11, which optimizes the opening and closing umbrella structure and prevents the umbrella frame assembly 1 from colliding with the user when the umbrella surface is opened and closed.

[0035] In summary, the umbrella opening mechanism 30 includes a connecting rod 31 and a movable seat 32. The movable seat 32 is fixedly engaged with the connecting rod 31. The connecting rod 31 passes through the lower umbrella disc 14 and can extend and retract relative to the lower umbrella disc 14. The upper part of the connecting rod 31 is fixedly engaged with the upper umbrella disc 12. The lower umbrella disc 14 is preferably fixedly installed on the upper end of the base 3. A connecting rod through hole 33 is provided in the middle of the lower umbrella disc 14, and the connecting rod 31 can move up and down along the connecting rod through hole 33. The movable seat 32 can move up and down through the lifting drive mechanism 4, and simultaneously drive the connecting rod 31 to move up and down. The connecting rod 31 can move the upper umbrella disc 12 away from or closer to the lower umbrella disc 14. When the upper umbrella disc 12 moves downward closer to the lower umbrella disc 14, the short umbrella rib 13 drives the long umbrella rib 11 to achieve outward support. When the upper umbrella disc 12 moves upward away from the lower umbrella disc 14, the short umbrella rib 13 drives the long umbrella rib 11 to achieve folding.

[0036] In combination with the above, the lifting drive mechanism 4 includes a handle part 41 and a lifting part 45. The handle part 41 is provided with a slider part 411, which is fixedly connected to the base 3 and the lifting part 45. Usually, the three are fixedly installed by bolts, which facilitates the driving of the handle part 41 and realizes the overall driving of the base 3. A sliding groove 21 is provided on one side of the umbrella column 2. The slider part 411 can move up and down in the sliding groove 21 and drive the base 3 to move up and down.

[0037] In conjunction with the above, the handle part 41 also includes a locking part 412, and a locking groove 22 is also provided on one side of the umbrella column 2. Preferably, in this embodiment, there are two locking parts 412 and two locking grooves 22. The locking parts 412 are provided on both sides of the slider part 411, and the locking grooves 22 are provided on both sides of the sliding groove 411. When the lifting drive mechanism 4 is in the process of rising, the locking part 412 abuts against the side surface of the umbrella column 2 and rises together with the lifting drive mechanism 4. When the lifting drive mechanism 4 rises to the designated position, the locking part 412 is embedded in the locking groove 22 and forms a locking limit with the locking groove 22 to prevent the umbrella rib assembly 1 from extending excessively out of the umbrella column 2.

[0038] In conjunction with the above installation structure, preferably, a pressing wrench is provided on the outer side of the locking part 412. When the locking part 412 and the locking groove 22 form a locking limit, applying pressure to the pressing wrench can cause the locking part 412 to leave the locking groove 22 and release the limit, at which point the lifting drive mechanism 4 can be operated to descend. In other embodiments, structures commonly used in the prior art, such as elastic element locking limit and magnetic locking limit, can also be used.

[0039] In conjunction with the above, the lifting drive mechanism 4 also includes a drive wheel 42, a transmission belt 43, and a pulley 44. The drive wheel 42 is located inside the lifting part 45, and the shaft of the handle part 41 passes through and connects to the drive wheel 42 to drive the drive wheel 42 to rotate. The transmission belt 43 is used to drive the drive wheel 42, and the transmission belt 43 surrounds the pulley 44 to drive the umbrella opening mechanism 30 to move. The pulley 44 is located in the upper inner cavity of the base and is usually provided with a pulley seat for easy installation. The pulley 44 is used to guide the transmission belt 43 in a circular manner. The drive wheel 42 drives the transmission belt 43 to move, so that the movable seat 32, which is fixedly installed at both ends, can be driven to different positions. Specifically, the movable seat 43 can be adjusted to different heights. Preferably, in this embodiment, the transmission belt 43 can be a pulley or chain, and the drive wheel 42 and pulley 44 can be sprockets. In addition, the outer sides of the drive wheel 42 and pulley 44 can also be provided with transmission teeth, and the inner side of the transmission belt 43 can be provided with matching tooth grooves. The transmission teeth and tooth grooves mesh with each other, making the transmission process more stable and smooth.

[0040] In summary, one end of the transmission belt 43 is fixedly engaged with the movable seat 32 and extends to the drive wheel 42. After the transmission belt 43 wraps around the drive wheel 42, it extends to the pulley 44 and then wraps around the pulley 44 before the other end is fixedly engaged with the movable seat 32. The pulley 44 is located in the upper part of the base 3. The movable seat 32 is driven by the transmission belt 43 to move along the height between the pulley 44 and the drive wheel 42. The transmission belt 43 forms a loop structure. Driven by the drive wheel 42, the transmission belt 43 reciprocates, thereby driving the movable seat 32 to move.

[0041] In conjunction with the above installation structure, the movable base 32 is provided with a connecting rod through hole 33, and the connecting rod 31 passes through the connecting rod through hole 33. The movable base 32 is also provided with a transmission belt fixing groove 321 and a transmission belt through groove 322. The transmission belt fixing groove 321 is used to fix the end of the transmission belt 43, and the transmission belt through groove 322 is used to allow the transmission belt 43 to pass through and move.

[0042] In this embodiment, based on the above installation structure, there are two transmission belt fixing grooves 321, which are respectively located at the lower part near the edge and the upper part near the center of the movable seat 32. The transmission belt through groove 322 is located on one side of the movable seat 32 near the edge. One end of the transmission belt 32 is fixed in one of the transmission belt fixing grooves 321, and the other end wraps around the lower part of the drive wheel 42, passes through the transmission belt through groove 322, then wraps around the upper part of the pulley 44, and finally is fixed in the other transmission belt fixing groove 321.

[0043] In combination with the above, the handle part 41 can adopt a handle structure commonly found in the prior art, such as a hand crank or an electric handle, so as to realize the transmission and drive of the drive wheel 42. The up and down movement of the handle part 41 itself is achieved by manual push and pull operation.

[0044] Combining the above installation structure, the opening and use process of this utility model is as follows: The user can push the slider part 411 of the handle part 41 upward along the sliding groove 21 until the locking part 412 locks and limits with the locking groove 22. At this time, the umbrella frame assembly 1 is in the retracted state, and the long umbrella ribs 11 are all extended outside the umbrella column 2. By rotating the handle part 41, the drive wheel 42 is rotated. Under the cooperation of the pulley 44, the transmission belt 43 is moved, and the end of the transmission belt 43 pulls the moving seat 32, causing the moving seat 32 to move downward, and driving the connecting rod 31 and the upper umbrella plate 12 to move downward. The upper umbrella plate 12 exerts pressure on the short umbrella ribs 13, which is then transmitted to the long umbrella ribs 11, causing the long umbrella ribs 11 to open. At this time, the sun umbrella is in the open state.

[0045] Conversely, by rotating the handle 41 in the opposite direction, the moving seat 12 moves upward under the transmission of the drive wheel 42, the transmission belt 43, and the pulley 44. The short umbrella rib 13 drives the long umbrella rib 11 to move upward. At this time, the umbrella frame assembly 1 is in the retracted state. Then, pressure is applied to the pressing wrench on the outside of the locking part 412, causing the locking part 412 to leave the locking groove 22 and release the limit. At this time, the user can push the slider part 411 of the handle 41 downward along the sliding groove 21, so that the umbrella frame assembly 1 is retracted into the cavity of the umbrella column 2. At this time, the parasol is in the closed state.

[0046] In combination with the above, a top plate 5 is provided at the top of the umbrella column, and a lamp body is fitted on the top plate 5. A closing groove 51 is provided on the upper surface of the top plate 5. The closing groove 51 has a bowl-shaped structure and an umbrella frame closing cavity 52 is provided inside the closing groove 51. The umbrella frame closing cavity 52 is used to communicate and cooperate with the inner cavity of the umbrella column 2, so that the opening and closing process of the umbrella frame assembly 1 is smoother and the long umbrella ribs 11 and the umbrella cloth are less prone to wear.

[0047] In summary, the lamp body can adopt the structure of incandescent lamps or LED lamps commonly used in the prior art, or it can adopt the solar lamp in the solar sunshade disclosed in the announcement number CN202233459U.

[0048] The sunshade umbrella corresponding to this embodiment is usually used for sunshade and is particularly suitable for indoor decoration. Due to its usage characteristics, it is not recommended for use on rainy days.

[0049] This utility model's umbrella fabric can be stored inside the umbrella pole, greatly saving space. The folding and closing process is simple and convenient. The optimized umbrella rib structure ensures that the umbrella ribs will not collide with the user when the umbrella is opened or closed, thus improving the user experience.

[0050] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the utility model. Any simple modifications, equivalent changes, or alterations made to the above embodiments based on the technical principles of the present utility model shall still fall within the scope of the technical solution of the present utility model.
