Description

Technical Field

[0001] The present application belongs to the technical field of folding umbrellas, and in particular relates to an automatically opening and closing folding umbrella. Background Art

[0002] Automatic folding umbrellas offer convenient, one-handed operation and are now widely used in daily life. However, current automatic folding umbrellas are typically semi-automatic, meaning they automatically open and close. When closing, only the umbrella's canopy automatically retracts, while the handle must be manually retracted. This results in poor automatic opening and closing performance, impacting the user experience. Utility Model Content

DETAILED DESCRIPTION

[0061] The following are preferred implementations of the present application. It should be noted that ordinary technicians in this technical field can make several improvements and modifications without departing from the principles of the present application. These improvements and modifications are also considered to be within the scope of protection of the present application.

[0062] In view of this, in order to solve the above problems, this application provides an automatic opening and closing folding umbrella. Please refer to Figure 1-Figure 3 , Figure 1 This is a schematic diagram of the three-dimensional structure of an automatically opening and closing folding umbrella in one embodiment of the present application. Figure 2 for Figure 1 Schematic diagram of an automatically opening and closing folding umbrella. Figure 3This is a schematic diagram of the three-dimensional structure of the reversing assembly and the guide wheel when they cooperate in one embodiment of the present application.

[0063] The automatic opening and closing folding umbrella 1 provided in this embodiment includes a handle assembly 10, a guide wheel 20, a transmission assembly 30, an umbrella shaft assembly 40, and a canopy assembly 50. The handle assembly 10 includes a rotating member 11, the guide wheel 20 is movably connected to the rotating member 11, and the rotating member 11 can rotate the guide wheel 20 in a first direction or a second direction, wherein the first direction is opposite to the second direction. The transmission assembly 30 is movably connected to the guide wheel 20. The umbrella shaft assembly 40 is disposed on the handle assembly 10 and movably connected to the transmission assembly 30. The canopy assembly 50 is disposed on the umbrella shaft assembly 40 and movably connected to the transmission assembly 30. When the guide wheel 20 rotates in the first direction, the umbrella shaft assembly 40 and the canopy assembly 50 can be deployed via the transmission assembly 30. When the guide wheel 20 rotates in the second direction, the umbrella shaft assembly 40 and the canopy assembly 50 can be retracted via the transmission assembly 30.

[0064] The main application scenarios of the automatic opening and closing folding umbrella 1 provided in this embodiment include but are not limited to shielding against wind and rain and shielding against sunlight. The automatic opening and closing folding umbrella 1 can automatically put the umbrella into an expanded state or a retracted state.

[0065] The automatically opening and closing folding umbrella 1 primarily comprises a handle assembly 10, a guide wheel 20, a transmission assembly 30, an umbrella pole assembly 40, and an umbrella canopy assembly 50. The handle assembly 10 primarily houses and secures other components and provides a gripping base. The handle assembly 10 includes a rotating member 11. The rotating member 11 is rotatable and primarily serves to power the transmission assembly 30. Optionally, the rotating member 11 can be manually driven or driven by a motor. The guide wheel 20 primarily cooperates with the rotating member 11 to rotate in a first direction or a second direction, with the first direction being opposite to the second direction.

[0066] In other words, the guide wheel 20 can directly cooperate with the rotating member 11, and the forward and reverse rotation of the rotating member 11 causes the guide wheel 20 to rotate in the first direction or the second direction. The guide wheel 20 can also cooperate with the rotating member 11 indirectly, that is, the rotating member 11 drives other components, and these other components cooperate with the guide wheel 20 to cause the guide wheel 20 to rotate in the first direction or the second direction. The first direction is opposite to the second direction. For example, if the first direction is clockwise, the second direction is counterclockwise, or if the first direction is counterclockwise, the second direction is clockwise.

[0067] The transmission assembly 30 primarily connects the various components of the automatically opening and closing folding umbrella 1 and coordinates them. The transmission assembly 30 is movably connected to the guide wheel 20, meaning it is connected to the guide wheel 20 and can move relative to the guide wheel 20. When the guide wheel 20 rotates in a first or second direction, the guide wheel 20 pulls on various components of the transmission assembly 30, causing the transmission assembly 30 to achieve different movements. The umbrella shaft assembly 40 connects the umbrella handle assembly 10 and the umbrella canopy assembly 50. It is a rod-shaped structure composed of multiple short rods that can slide relative to each other to extend or retract the umbrella shaft assembly 40. The umbrella shaft assembly 40 primarily cooperates with the transmission assembly 30 to expand or retract. One end of the umbrella shaft assembly 40 is connected to the umbrella handle assembly 10. The umbrella shaft assembly 40 is also movably connected to the transmission assembly 30. In other words, the umbrella shaft assembly 40 is connected to the transmission assembly 30 and can move relative to the transmission assembly 30. When the transmission assembly 30 performs various movements, it can cause the umbrella shaft assembly 40 to expand or retract. The canopy assembly 50, the portion of the umbrella that provides shade from the sun or rain, primarily cooperates with the transmission assembly 30 to expand or close. The canopy assembly 50 is fixed to one end of the umbrella shaft assembly 40 and is movably connected to the transmission assembly 30. In other words, the canopy assembly 50 is connected to the transmission assembly 30 and can move relative to the transmission assembly 30. When the transmission assembly 30 performs various movements, it can cause the canopy assembly 50 to expand or retract.

[0068] Automatically opening and closing folding umbrellas in the related art are typically semi-automatic. This means the umbrella can automatically expand and close, but the shaft can only automatically expand and not retract. Furthermore, retracting the shaft requires considerable force, making it difficult for some users with limited strength to do so. Furthermore, when users are carrying weight in both hands or have limited mobility, it is often difficult to conveniently close the umbrella with one hand.

[0069] Furthermore, some fully retractable, automatically opening and closing umbrellas are mostly powered by electric mechanisms. This not only increases the cost of the umbrella but also increases the user's reliance on electricity during use. For example, when the battery of an electric umbrella is depleted, its automatic opening and closing functions become inconvenient for users who often forget to recharge. Furthermore, humid working environments, even those exposed to water, place higher demands and challenges on the waterproofing of the electric umbrella's circuit system. Furthermore, this reliance on electricity increases the generation of electronic waste, particularly consumables like batteries, which is detrimental to environmental protection.

[0070] In this embodiment, when the rotating member 11 rotates, it can drive other components to rotate, and through various components, it can cooperate with the guide wheel 20, thereby causing the guide wheel 20 to rotate in a first direction or a second direction indirectly driven by the rotating member 11. When the guide wheel 20 rotates in the first direction or the second direction, it can drive the transmission assembly 30 to achieve different movements, thereby causing the transmission assembly 30 to drive the umbrella shaft assembly 40 and the umbrella cover assembly 50 to simultaneously deploy, or the transmission assembly 30 to drive the umbrella shaft assembly 40 and the umbrella cover assembly 50 to simultaneously retract, thereby deploying or retracting the automatically opening and closing folding umbrella 1. The specific manner in which the guide wheel 20 cooperates with the rotating member 11 and the transmission structure of the transmission assembly 30 will be described in detail below.

[0071] In summary, this embodiment enables the rotating member 11 to directly or indirectly cooperate with the guide wheel 20, thereby enabling the rotating member 11 to drive the guide wheel 20 to rotate in a first direction or a second direction, thereby enabling the guide wheel 20 to drive the transmission assembly 30 to achieve different movements. When the guide wheel 20 rotates in the first direction, the transmission assembly 30 pulls the umbrella shaft assembly 40 and the umbrella cover assembly 50 to move, thereby causing the umbrella shaft assembly 40 to deploy and the umbrella cover assembly 50 to expand. When the guide wheel 20 rotates in the second direction, the transmission assembly 30 pulls the umbrella shaft assembly 40 and the umbrella cover assembly 50 to move, thereby causing the umbrella shaft assembly 40 to retract and the umbrella cover assembly 50 to close. This achieves the full deployment and retraction of the automatically opening and closing folding umbrella 1, simplifying the deployment and retraction methods and reducing the difficulty of operation.

[0072] As can be seen from the above content, the umbrella pole assembly 40 is deployed by cooperating with the transmission assembly 30. This embodiment provides two ways in which the umbrella pole assembly 40 cooperates with the transmission assembly 30, which will be described in detail below.

[0073] Please refer to Figure 4-Figure 5 , Figure 4 Schematic diagram of the first transmission module of the umbrella pole assembly during the unfolding process in one embodiment of the present application. Figure 5 This is a schematic diagram of the first transmission module when the umbrella pole assembly is unfolded in another embodiment of the present application.

[0074] In this embodiment, the umbrella pole assembly 40 includes a first umbrella pole 41, a second umbrella pole 42, and a third umbrella pole 43. The umbrella handle assembly 10 is arranged at one end of the first umbrella pole 41. The second umbrella pole 42 and the third umbrella pole 43 can slide along the extension direction of the first umbrella pole 41 to approach or move away from the umbrella handle assembly 10.

[0075] The transmission assembly 30 includes a first transmission module 31, which includes a first traction rope 311, a second traction rope 312, a first pulley 314, and a second pulley 315. The first pulley 314 is arranged on the first umbrella pole 41. One end of the first traction rope 311 is connected to the guide wheel 20, and the other end of the first traction rope 311 is connected to the second umbrella pole 42 by being wound around the first pulley 314. The distance between the first pulley 314 and the umbrella handle assembly 10 is not less than the distance between the other end of the first traction rope 311 and the umbrella handle assembly 10.

[0076] The second pulley 315 is provided on the second umbrella pole 42, one end of the second traction rope 312 is connected to the third umbrella pole 43, and the other end of the second traction rope 312 is connected to the first umbrella pole 41 or the umbrella handle assembly 10 by being wound around the second pulley 315, and the distance between the second pulley 315 and the umbrella handle assembly 10 is not less than the distance between one end of the second traction rope 312 and the umbrella handle assembly 10.

[0077] Alternatively, the transmission assembly 30 includes a first transmission module 31, the first transmission module 31 includes a first traction rope 311, a first pulley 314, a second pulley 315, and a third pulley 316, the first pulley 314 is arranged on the first umbrella pole 41, the third pulley 316 and the second pulley 315 are arranged on the second umbrella pole 42, one end of the first traction rope 311 is connected to the guide wheel 20, and the other end of the first traction rope 311 is connected to the third umbrella pole 43 by sequentially winding around the first pulley 314, the second pulley 315, and the third pulley 316.

[0078] The distance between the first pulley 314 and the umbrella handle assembly 10 is greater than the distance between the second pulley 315 and the umbrella handle assembly 10, the distance between the third pulley 316 and the umbrella handle assembly 10 is greater than the distance between the second pulley 315 and the umbrella handle assembly 10, and the distance between the third pulley 316 and the umbrella handle assembly 10 is not less than the distance between the other end of the first traction rope 311 and the umbrella handle assembly 10.

[0079] Among them, when the guide wheel 20 rotates along the first direction, the first rotating module pulls the second umbrella rod 42 and the third umbrella rod 43 to slide in the direction away from the umbrella handle assembly 10, thereby making the umbrella rod assembly 40 unfold, and at the same time the first transmission module 31 also drives the umbrella cover assembly 50 to unfold.

[0080] In this embodiment, the umbrella shaft assembly 40 can be divided into three parts: a first umbrella shaft 41, a second umbrella shaft 42, and a third umbrella shaft 43. Optionally, the three sections can be arranged so that the second umbrella shaft 42 is nested within the first umbrella shaft 41, and the third umbrella shaft 43 is nested within the second umbrella shaft 42, i.e., from the inside out, the first umbrella shaft 41, the second umbrella shaft 42, and the third umbrella shaft 43 are nested. Alternatively, the three sections can be arranged so that the second umbrella shaft 42 is nested within the third umbrella shaft 43, and the first umbrella shaft 41 is nested within the second umbrella shaft 42, i.e., from the inside out, the third umbrella shaft 43, the second umbrella shaft 42, and the first umbrella shaft 41 are nested. This embodiment is merely illustrative of the positional relationship, from the inside out, of the first umbrella shaft 41, the second umbrella shaft 42, and the third umbrella shaft 43.

[0081] The umbrella handle assembly 10 is arranged at one end of the first umbrella rod 41, such as Figure 4 As shown, the umbrella handle assembly 10 is arranged below the first umbrella rod 41. The second umbrella rod 42 and the third umbrella rod 43 can slide along the extension direction of the first umbrella rod 41, that is, Figure 4 As shown, when the second umbrella pole 42 and the third umbrella pole 43 slide upward and away from the umbrella handle assembly 10, the umbrella pole assembly 40 is unfolded. When the second umbrella pole 42 and the third umbrella pole 43 slide downward and approach the umbrella handle assembly 10, the umbrella pole assembly 40 is retracted.

[0082] Optionally, the first umbrella rod 41 has a first limiting portion, the second umbrella rod 42 has a second limiting portion, and the third umbrella rod 43 has a third limiting portion, which are mainly used to limit the second umbrella rod 42 and the third umbrella rod 43. When the umbrella rod assembly 40 is unfolded, the first limiting portion, the second limiting portion, and the third limiting portion can limit the sliding distance of the second umbrella rod 42 and the third umbrella rod 43, thereby preventing the first umbrella rod 41, the second umbrella rod 42, and the third umbrella rod 43 from separating from each other.

[0083] In one embodiment, the transmission assembly 30 includes a first transmission module 31, and the first transmission module 31 includes a first traction rope 311, a second traction rope 312, a first pulley 314, and a second pulley 315. The traction rope is mainly used to pull the components connected to the traction rope to move, and the pulley 33 is mainly used to cooperate with the traction rope to change the direction of traction. The first pulley 314 is fixed in the first umbrella pole 41, one end of the first traction rope 311 is fixed to the guide wheel 20, and the other end of the first traction rope 311 is wound and transmission-connected to the first pulley 314 and then connected to the second umbrella pole 42. At the same time, the distance from the first pulley 314 to the umbrella handle assembly 10 is not less than the distance from the other end of the first traction rope 311 to the umbrella handle assembly 10. In other words, Figure 4 As shown, the height of the first pulley 314 is greater than or equal to the height of the other end of the first traction rope 311.

[0084] The second pulley 315 is fixed in the second umbrella pole 42, that is, the second pulley 315 moves synchronously with the second umbrella pole 42. One end of the second traction rope 312 is fixed to the third umbrella pole 43. The other end of the second traction rope 312 is wound around and connected to the second pulley 315 and then connected to the first umbrella pole 41 or the umbrella handle assembly 10. At the same time, the distance between the second pulley 315 and the umbrella handle assembly 10 is not less than the distance between one end of the second traction rope 312 and the umbrella handle assembly 10. In other words, Figure 4 As shown, the height of the second pulley 315 is greater than or equal to the height of one end of the second traction rope 312.

[0085] Specifically, if Figure 4 As shown, in this embodiment, the first pulley 314 can be located at the top of the first umbrella shaft 41, and the second pulley 315 can be located at the top of the second umbrella shaft 42. One end of the first traction rope 311 is fixed to the guide wheel 20, and the other end is wound around the first pulley 314 and fixed to the bottom end of the second umbrella shaft 42. One end of the second traction rope 312 is fixed to the umbrella handle assembly 10, and the other end is wound around the second pulley 315 and fixed to the bottom end of the third umbrella shaft 43. When the guide wheel 20 rotates in the first direction, the guide wheel 20 pulls the first traction rope 311 around the guide wheel 20. That is, the guide wheel 20 pulls the first traction rope 311 downward, causing the first traction rope 311 to pull the second umbrella shaft 42 upward. When the second umbrella shaft 42 slides upward, the second pulley 315 also moves upward synchronously, causing the left side of the second traction rope 312 to extend, that is, the right side of the traction rope to shorten, thereby causing the second traction rope 312 to pull the third umbrella shaft 43 upward. That is, the second umbrella pole 42 and the third umbrella pole 43 both slide upward, thereby realizing the deployment of the umbrella pole assembly 40 .

[0086] In another embodiment, the transmission assembly 30 includes a first transmission module 31, which includes a first traction rope 311, a first pulley 314, a second pulley 315, and a third pulley 316. The traction rope is primarily used to pull the components in motion, and the pulley 33 is primarily used to cooperate with the traction rope to change the direction of traction. The first pulley 314 is fixed within the first umbrella shaft 41, and the third pulley 316 and the second pulley 315 are both fixed within the second umbrella shaft 42. That is, the third pulley 316 and the second pulley 315 move synchronously with the second umbrella shaft 42. One end of the first traction rope 311 is fixed to the guide wheel 20, and the other end is sequentially wound around and transmission-connected to the first pulley 314, the second pulley 315, and the third pulley 316, and finally connected to the third umbrella shaft 43.

[0087] At the same time, the distance between the first pulley 314 and the umbrella handle assembly 10 is greater than the distance between the second pulley 315 and the umbrella handle assembly 10, the distance between the third pulley 316 and the umbrella handle assembly 10 is greater than the distance between the second pulley 315 and the umbrella handle assembly 10, and the distance between the third pulley 316 and the umbrella handle assembly 10 is not less than the distance between the other end of the first traction rope 311 and the umbrella handle assembly 10. In other words, if Figure 5 As shown, the height of the first pulley 314 is greater than the height of the second pulley 315 , the height of the third pulley 316 is greater than the height of the second pulley 315 , and the height of the third pulley 316 is greater than or equal to the height of the other end of the first traction rope 311 .

[0088] Specifically, if Figure 5 As shown, in this embodiment, the first pulley 314 can be disposed at the top of the first umbrella pole 41, the second pulley 315 can be disposed at the bottom of the second umbrella pole 42, and the third umbrella pole 43 can be disposed at the top of the second umbrella pole 42. One end of the first traction rope 311 is fixed to the guide wheel 20, and the other end is sequentially wound around the first pulley 314, the second pulley 315, and the third pulley 316 before being finally fixed to the bottom end of the third umbrella pole 43. When the guide wheel 20 rotates in the first direction, the guide wheel 20 pulls the first traction rope 311 around the guide wheel 20. That is, the guide wheel 20 pulls the first traction rope 311 downward, shortening the length of the first traction rope 311 and thereby pulling the second pulley 315 upward, i.e., causing the second umbrella pole 42 to slide upward. Simultaneously, the shortening of the first traction rope 311 shortens the length of the first traction rope 311 between the other end of the first traction rope 311 and the third pulley 316, thereby causing the first traction rope 311 to pull the third umbrella pole 43 upward. That is, the second umbrella pole 42 and the third umbrella pole 43 slide upward at the same time, thereby realizing the deployment of the umbrella pole assembly 40 .

[0089] In the above two embodiments, when the guide wheel 20 rotates in the second direction, i.e., when the umbrella shaft assembly 40 is retracted, the guide wheel 20 releases the first traction rope 311, thereby allowing the various components to return to the positions at the time when the umbrella shaft assembly 40 was retracted, thereby enabling the next deployment of the umbrella shaft assembly 40. In this embodiment, the provision of the first transmission assembly 30 enables the guide wheel 20 to drive the first transmission assembly 30 when the guide wheel 20 rotates in the first direction, thereby causing the first transmission assembly 30 to pull the umbrella shaft assembly 40 to deploy. This simplifies the structure and reduces the difficulty of operation and production.

[0090] As can be seen from the above content, the umbrella cover assembly 50 cooperates with the transmission assembly 30 to achieve the expansion and retraction of the umbrella cover assembly 50. This embodiment provides two ways of cooperating between the umbrella cover assembly 50 and the transmission assembly 30, which will be described in detail below.

[0091] Please refer to Figure 6-Figure 8 , Figure 6This is a schematic diagram of the first transmission module when the umbrella cover assembly is unfolded in one embodiment of the present application. Figure 7 This is a schematic diagram of the first transmission module when the umbrella cover assembly is unfolded in another embodiment of the present application. Figure 8 for Figure 1 Schematic diagram of the umbrella cover assembly of the automatic opening and closing folding umbrella shown.

[0092] In this embodiment, the umbrella pole assembly 40 includes a first umbrella pole 41, a second umbrella pole 42, and a third umbrella pole 43. The umbrella handle assembly 10 is arranged at one end of the first umbrella pole 41. The second umbrella pole 42 and the third umbrella pole 43 can slide along the extension direction of the first umbrella pole 41 to approach or move away from the umbrella handle assembly 10.

[0093] The transmission assembly 30 includes a first transmission module 31, which includes a fourth pulley 317, a fifth pulley 318, a third traction rope 313, and a center plate 319. The center plate 319 is sleeved on the third umbrella pole 43 and can slide along the extension direction of the third umbrella pole 43. The fourth pulley 317 is provided on the third umbrella pole 43, and the fifth pulley 318 is provided on the center plate 319. One end of the third traction rope 313 is connected to the first umbrella pole 41 or the second umbrella pole 42, and the other end of the third traction rope 313 is connected to the third umbrella pole 43 by being wound around the fourth pulley 317 and the fifth pulley 318 in sequence.

[0094] The distance between the fourth pulley 317 and the umbrella handle assembly 10 is not less than the distance between the fifth pulley 318 and the umbrella handle assembly 10, the distance between the fourth pulley 317 and the umbrella handle assembly 10 is not less than the distance between one end of the third traction rope 313 and the umbrella handle assembly 10, and the distance between the other end of the third traction rope 313 and the umbrella handle assembly 10 is not less than the distance between the fifth pulley 318 and the umbrella handle assembly 10.

[0095] Alternatively, the transmission assembly 30 includes a first transmission module 31, which includes a fourth pulley 317, a third traction rope 313, and a center plate 319. The center plate 319 is sleeved on the third umbrella shaft 43 and can slide along the extension direction of the third umbrella shaft 43. The fourth pulley 317 is provided on the third umbrella shaft 43. One end of the third traction rope 313 is connected to the first umbrella shaft 41 or the second umbrella shaft 42, and the other end of the third traction rope 313 is connected to the center plate 319 by being wound around the fourth pulley 317. The distance between the fourth pulley 317 and the umbrella handle assembly 10 is no less than the distance between the two ends of the third traction rope 313 and the umbrella handle assembly 10.

[0096] When the umbrella pole assembly 40 is unfolded, the umbrella pole assembly 40 is extended, so that the third traction rope 313 pulls the middle plate 319 to slide in a direction away from the umbrella handle assembly 10, so that the umbrella cover assembly 50 is unfolded.

[0097] The specific structure of the umbrella shaft assembly 40 has been described in detail above in this application and will not be further elaborated in this embodiment. In one embodiment, the transmission assembly 30 includes a first transmission module 31, which includes a fourth pulley 317, a fifth pulley 318, a third traction rope 313, and a center plate 319. The traction rope is primarily used to pull the components in motion, while the pulley 33 is primarily used to cooperate with the traction rope to change the direction of traction. The center plate 319 is primarily used to slide along the extension direction of the third umbrella shaft 43 under the influence of the traction rope. The fourth pulley 317 is fixed to the third umbrella shaft 43, moving synchronously with the third umbrella shaft 43. The fifth pulley 318 is located in the center plate 319, moving synchronously with the center plate 319. One end of the third traction rope 313 is fixed to the first umbrella shaft 41 or the second umbrella shaft 42, and the other end is sequentially wound around and connected to the fourth pulley 317 and the fifth pulley 318, and finally connected to the third umbrella shaft 43.

[0098] At the same time, the distance between the fourth pulley 317 and the umbrella handle assembly 10 is not less than the distance between the fifth pulley 318 and the umbrella handle assembly 10. Figure 6 As shown, the height of the fourth pulley 317 is greater than or equal to the height of the fifth pulley 318. And the distance between the fourth pulley 317 and the umbrella handle assembly 10 is not less than the distance between one end of the third traction rope 313 and the umbrella handle assembly 10, that is, Figure 6 As shown, the height of the fourth pulley 317 is greater than or equal to the height of one end of the third traction rope 313. Moreover, the distance between the other end of the third traction rope 313 and the umbrella handle assembly 10 is not less than the distance between the fifth pulley 318 and the umbrella handle assembly 10, that is, Figure 6 As shown, the height of the other end of the third traction rope 313 is greater than or equal to the height of the fifth pulley 318.

[0099] like Figure 8As shown, the canopy assembly 50 includes ribs 51, support rods 52, and tension springs 53. The ribs 51 form the framework of the umbrella canopy structure. The support rods 52 primarily support the ribs 51, allowing the canopy assembly 50 to unfold. One end of the support rod 52 is pivotally connected to the center plate 319, and the other end is pivotally connected to the ribs 51. The tension springs 53 primarily connect the support rods 52 and the ribs 51. When the automatically opening and closing folding umbrella 1 is switched to the unfolded state, the center plate 319, pulled by the third traction rope 313, moves toward the top of the umbrella pole assembly 40. The center plate 319 drives the support rods 52 to prop up the ribs 51, thereby unfolding the canopy assembly 50. At this point, the tension springs 53 are in a stretched state. When the automatically opening and closing folding umbrella 1 is switched to the closed state, the tension springs 53 contract, bringing the support rods 52 and ribs 51 closer together. Simultaneously, the support rods 52 press against the center plate 319, causing it to move downward, closing the canopy assembly 50.

[0100] Specifically, if Figure 7 As shown, in this embodiment, the fourth pulley 317 is fixed to the top of the third umbrella shaft 43, the fifth pulley 318 is fixed to the middle plate 319, and one end of the third traction rope 313 is fixed to the umbrella handle assembly 10. The other end is sequentially wound around the fourth pulley 317 and the fifth pulley 318 before finally connecting to the top of the third umbrella shaft 43. When the umbrella shaft assembly 40 is deployed, the third traction rope 313 on the left side of the fourth pulley 317 is extended, thereby shortening the third traction rope 313 on the right side of the fourth pulley 317. This in turn causes the third traction rope 313 to pull the fifth pulley 318 upward relative to the third umbrella shaft 43. This causes the middle plate 319 to slide upward relative to the third umbrella shaft 43, thereby causing the umbrella canopy to deploy.

[0101] In another embodiment, the transmission assembly 30 includes a first transmission module 31, and the first transmission module 31 includes a fourth pulley 317, a third traction rope 313, and a middle disk 319. The traction rope is mainly used to move the traction component, and the pulley 33 is mainly used to cooperate with the traction rope to change the direction of traction. The middle disk 319 is mainly used to slide along the extension direction of the third umbrella pole 43 under the drive of the traction rope. The fourth pulley 317 is fixed in the third umbrella pole 43, that is, the fourth pulley 317 moves synchronously with the third umbrella pole 43. One end of the third traction rope 313 is fixed to the first umbrella pole 41 or the second umbrella pole 42, and the other end is fixed to the middle disk 319. At the same time, the distance between the fourth pulley 317 and the umbrella handle assembly 10 is not less than the distance between the two ends of the third traction rope 313 and the umbrella handle assembly 10, that is, Figure 7 As shown, the height of the fourth pulley 317 is greater than or equal to the height of the two ends of the third traction rope 313. The specific structure of the umbrella cover assembly 50 and the principle of the umbrella cover assembly 50 are described in detail above, and will not be repeated in this embodiment.

[0102] Specifically, if Figure 7As shown, in this embodiment, the fourth pulley 317 can be fixed to the top of the third umbrella pole 43, one end of the third traction rope 313 is fixed to the top of the second umbrella pole 42, and the other end is fixed to the middle plate 319. When the umbrella pole assembly 40 is deployed, the third traction rope 313 on the right side of the fourth pulley 317 is extended, thereby shortening the third traction rope 313 on the left side of the fourth pulley 317. In turn, the third traction rope 313 pulls the middle plate 319 to slide upward relative to the third umbrella pole 43, thereby deploying the umbrella canopy assembly 50.

[0103] In the two aforementioned embodiments, when the shaft assembly 40 and canopy assembly 50 are retracted, the third traction rope 313 between the fourth pulley 317 and the handle assembly 10 shortens, while the third traction rope 313 between the fourth pulley 317 and the center plate 319 lengthens. This allows the center plate 319 to return to the position it was in when the shaft assembly 40 was retracted, allowing the canopy assembly 50 to be deployed again. This embodiment, through the arrangement of the pulley 33 and traction rope, ensures that the canopy assembly 50 automatically expands when the shaft assembly 40 is deployed, and automatically closes when the shaft assembly 40 is retracted. This simplifies the structure and reduces the complexity of operation and production.

[0104] As can be seen from the above content, the umbrella pole assembly 40 is retracted by cooperating with the transmission assembly 30. This embodiment provides two ways in which the umbrella pole assembly 40 cooperates with the transmission assembly 30, which will be described in detail below.

[0105] Please refer to Figure 9-10 , Figure 9 Schematic diagram of the second transmission module of the umbrella pole assembly during the retraction process in one embodiment of the present application. Figure 10 This is a schematic diagram of the second transmission module when the umbrella pole assembly is retracted in another embodiment of the present application.

[0106] In this embodiment, the umbrella pole assembly 40 includes a first umbrella pole 41, a second umbrella pole 42, and a third umbrella pole 43. The umbrella handle assembly 10 is arranged at one end of the first umbrella pole 41. The second umbrella pole 42 and the third umbrella pole 43 can slide along the extension direction of the first umbrella pole 41 to approach or move away from the umbrella handle assembly 10.

[0107] The transmission assembly 30 includes a second transmission module 32, which includes a sixth pulley 322, a fourth traction rope 320, and a fifth traction rope 321. The sixth pulley 322 is provided on the first umbrella pole 41, and the sixth pulley 322 can slide along the extension direction of the umbrella pole assembly 40. One end of the fourth traction rope 320 is connected to the guide wheel 20, and the other end of the fourth traction rope 320 is fixed to the sixth pulley 322. One end of the fifth traction rope 321 is connected to the first umbrella pole 41, and the other end of the fifth traction rope 321 is connected to the third umbrella pole 43 by being wound around the sixth pulley 322. The distance between the two ends of the fifth traction rope 321 and the umbrella handle assembly 10 is not less than the distance between the sixth pulley 322 and the umbrella handle assembly 10.

[0108] Alternatively, the transmission assembly 30 includes a second transmission module 32 , and the second transmission module 32 includes a fourth traction rope 320 . One end of the fourth traction rope 320 is fixed to the guide wheel 20 , and the other end is fixed to the third umbrella pole 43 .

[0109] When the guide wheel 20 rotates along the second direction, the second transmission module 32 pulls the umbrella pole assembly 40 to retract.

[0110] The specific structure of the umbrella pole assembly 40 has been described in detail above in this application, and will not be repeated here in this embodiment. In one embodiment, the transmission assembly 30 includes a second transmission module 32, and the second transmission module 32 includes a sixth pulley 322, a fourth traction rope 320, and a fifth traction rope 321. The sixth pulley 322 is disposed in the first umbrella pole 41, and the sixth pulley 322 can slide in the first umbrella pole 41, that is, the sixth pulley 322 is a movable pulley 33. One end of the fourth traction rope 320 is connected to the guide wheel 20, and the other end is fixed to the sixth pulley 322, that is, Figure 9 As shown, the fourth traction rope 320 can pull the sixth pulley 322 to move downward. One end of the fifth traction rope 321 is connected to the first umbrella pole 41, and the other end is wound around and connected to the sixth pulley 322 and finally connected to the third umbrella pole 43. At the same time, the distance between the two ends of the fifth traction rope 321 and the umbrella handle assembly 10 is not less than the distance between the sixth pulley 322 and the umbrella handle assembly 10, that is, Figure 9 As shown, the heights of both ends of the fifth traction rope 321 are greater than or equal to the height of the sixth pulley 322 .

[0111] Specifically, if Figure 9 As shown, in this embodiment, the sixth pulley 322 can be disposed within the first umbrella pole 41, one end of the fourth traction rope 320 is connected to the guide wheel 20, and the other end is fixed to the sixth pulley 322. One end of the fifth traction rope 321 is fixed to the top of the first umbrella pole 41, and the other end is wound around the sixth pulley 322 and then fixed to the top of the third umbrella pole 43.

[0112] When the guide wheel 20 rotates in the second direction, it pulls the fourth traction rope 320, causing it to wrap around the guide wheel 20. Specifically, the fourth traction rope 320 pulls the sixth pulley 322 downward. As the sixth pulley 322 moves downward, the fifth traction rope 321 on the left side of the sixth guide wheel 20 lengthens, shortening the fifth traction rope 321 on the right side of the fifth traction rope 321. This in turn causes the fifth traction rope 321 to slide the third umbrella rod 43 downward. When the third umbrella rod 43 slides until its top abuts the top of the second umbrella rod 42, the third umbrella rod 43 pulls the second umbrella rod 42 downward as well, causing the umbrella rod assembly 40 to retract.

[0113] In another embodiment, the transmission assembly 30 includes a second transmission module 32, the second transmission module 32 includes a fourth traction rope 320, one end of the fourth traction rope 320 is fixed to the guide wheel 20, and the other end is fixed to the third umbrella pole 43. Specifically, Figure 10 As shown, the other end of the fourth pull rope 320 can be fixed to the top of the third umbrella pole 43. When the guide wheel 20 rotates in the second direction, the guide wheel 20 pulls the fourth pull rope 320, causing the fourth pull rope 320 to wrap around the guide wheel 20. In other words, the fourth pull rope 320 pulls the third umbrella pole 43 downward, causing the third umbrella pole 43 to slide downward. When the third umbrella pole 43 slides until its top abuts the top of the second umbrella pole 42, the third umbrella pole 43 pulls the second umbrella pole 42 downward as well, thereby retracting the umbrella pole assembly 40.

[0114] In the two aforementioned embodiments, when the umbrella shaft assembly 40 and the umbrella canopy assembly 50 are deployed, the guide wheel 20 releases the fourth traction rope 320, thereby returning the second transmission module 32 and the center plate 319 to the position when the umbrella shaft assembly 40 was deployed, thereby enabling the next retraction of the umbrella shaft assembly 40. In this embodiment, the second transmission assembly 30 is provided so that when the guide wheel 20 rotates in the second direction, the guide wheel 20 can drive the second transmission assembly 30, thereby causing the second transmission assembly 30 to pull the umbrella shaft assembly 40 to retract. This simplifies the structure and reduces the difficulty of operation and production.

[0115] Please refer to Figure 11 , Figure 11 Schematic diagram of the three-dimensional structure of the pulley in one embodiment of the present application. Optionally, the pulley 33 in the above embodiment is provided with a wire groove 330, that is, Figure 11 As shown, the pulley 33 is a structure with a concave center and convex sides. By setting the wire groove 330, the traction rope can be stably set in the wire groove 330, that is, the traction rope is stably connected to the guide wheel 20, reducing the risk of separation from the guide wheel 20.

[0116] Please refer to Figure 12 , Figure 12 Schematic diagram of the three-dimensional structure of the pulley fixing seat in one embodiment of the present application. Optionally, the umbrella pole assembly 40 further includes a pulley fixing seat 34, and the pulley 33 mentioned above is fixed to the pulley fixing seat 34 and thus fixed in the umbrella pole assembly 40.

[0117] Please refer to Figure 13 , Figure 13 for Figure 1 A schematic diagram of the three-dimensional structure of some components of the pole assembly of an automatically opening and closing folding umbrella is shown. Optionally, a wiring groove 44 is provided on the inner wall of the pole assembly 40. The wiring groove 44 is mainly used to accommodate the traction rope. The provision of the wiring groove 44 reduces the resistance encountered by the transmission assembly 30 when passing through the interior of the pole assembly 40, thereby reducing the resistance when the automatically opening and closing folding umbrella 1 is opened and closed.

[0118] Please refer to Figure 14 , Figure 14 The figure is a schematic diagram of the three-dimensional structure of a guide wheel in one embodiment of the present application. Optionally, the guide wheel 20 has a winding groove 21. When the guide wheel 20 rotates in a first direction, the first traction rope 311 is wound into the winding groove 21, and the fourth traction rope 320 is released from the winding groove 21. When the guide wheel 20 rotates in a second direction, the fourth traction rope 320 is wound into the winding groove 21, and the first traction rope 311 is released from the winding groove 21. The provision of the winding groove 21 makes it easier to wind the traction rope around the guide wheel 20.

[0119] Please refer to Figure 15 , Figure 15 This is a schematic diagram of the three-dimensional structure of a guide wheel in another embodiment of the present application. Optionally, the guide wheel 20 has two winding grooves 21. When the guide wheel 20 rotates in a first direction, the first traction rope 311 is wound into one winding groove 21, and the fourth traction rope 320 is released from the other winding groove 21. When the guide wheel 20 rotates in a second direction, the fourth traction rope 320 is wound into the other winding groove 21, and the first traction rope 311 is released from one winding groove 21. The provision of two winding grooves 21 prevents the two traction ropes from interfering with each other during winding and releasing, thereby reducing resistance during the expansion and closure of the automatically opening and closing folding umbrella 1.

[0120] Furthermore, optionally, when the traction rope is wound around the guide wheel 20 to the limit, the thickness of the traction rope is less than the depth of the winding groove 21. That is, when the traction rope is completely wound around the guide wheel 20, the traction rope is still completely within the winding groove 21, thereby preventing the traction rope from escaping from the guide wheel 20 and being entangled with other components, thereby preventing the automatic opening and closing folding umbrella 1 from being properly unfolded or closed.

[0121] Please refer to Figure 3 、 Figure 16-17 , Figure 16This is a schematic diagram of a partial three-dimensional structure of an automatically opening and closing folding umbrella in another embodiment of the present application. Figure 17 The figure is a schematic diagram of the three-dimensional structure of the reversing assembly and the guide wheel in another embodiment of the present application. In this embodiment, the automatic opening and closing folding umbrella 1 further includes a reversing assembly 60, which includes a first mating member 61 and a second mating member 62. When the guide wheel 20 engages with the first mating member 61, the first mating member 61 drives the guide wheel 20 to rotate in the first direction. When the guide wheel 20 engages with the second mating member 62, the second mating member 62 drives the guide wheel 20 to rotate in the second direction. When the guide wheel 20 engages with both the first mating member 61 and the second mating member 62, the guide wheel 20, the first mating member 61, and the second mating member 62 stop rotating.

[0122] In this embodiment, the automatically opening and closing folding umbrella 1 may further include a reversing assembly 60, which is primarily used to cooperate with the guide wheel 20 to change the rotational direction of the guide wheel 20. The reversing assembly 60 includes a first mating member 61 and a second mating member 62. The first mating member 61 and the second mating member 62 are capable of synchronous rotation driven by the rotating member 11. Optionally, the first mating member 61 and the second mating member 62 include, but are not limited to, cylindrical gears, bevel gears, etc. In this embodiment, the first mating member 61 and the second mating member 62 are only illustrated as bevel gears. The first mating member 61 and the second mating member 62 are capable of rotation, and the guide wheel 20 can cooperate with at least one of the first mating member 61 or the second mating member 62.

[0123] When the guide wheel 20 engages with the first engaging member 61, the first engaging member 61 can drive the guide wheel 20 to rotate synchronously, thereby causing the guide wheel 20 to rotate in a first direction. When the guide wheel 20 engages with the second engaging member 62, the second engaging member 62 can drive the guide wheel 20 to rotate synchronously, thereby causing the guide wheel 20 to rotate in a second direction. The guide wheel 20 can also engage with the first engaging member 61 and the second engaging member 62 simultaneously. In this case, the guide wheel 20 clamps the first engaging member 61 and the second engaging member 62, preventing them from rotating. This causes the guide wheel 20, the first engaging member 61, and the second engaging member 62 to all be stationary.

[0124] In this embodiment, the reversing assembly 60 enables the guide wheel 20 to engage with either the first mating member 61 or the second mating member 62, thereby enabling the guide wheel 20 to rotate in either the first or second direction. Furthermore, when the guide wheel 20 engages with both the first and second mating members 61 and 62 simultaneously, the guide wheel 20 remains stationary. This allows the guide wheel 20 to more easily switch between the first and second rotational directions.

[0125] From the above, it can be seen that the reversing assembly 60 has a first mating member 61 and a second mating member 62. The guide wheel 20 cooperates with the first mating member 61 or the second mating member 62 to achieve the rotation of the guide wheel 20 in the first direction or the second direction. This embodiment provides two mating modes of the reversing assembly 60, which will be described in detail below.

[0126] Please refer to Figure 17-18 , Figure 18 The figure is a schematic diagram of the three-dimensional structure of the switch and the reversing assembly in accordance with one embodiment of the present application. In this embodiment, the first mating member 61 and the second mating member 62 are sleeved on the rotating member 11 and rotate synchronously with the rotating member 11. The guide wheel 20 is disposed between the first mating member 61 and the second mating member 62. The first mating member 61 and the second mating member 62 are able to move relative to the guide wheel 20 along the arrangement direction of the first mating member 61 and the second mating member 62, thereby enabling the guide wheel 20 to engage with at least one of the first mating member 61 and the second mating member 62.

[0127] In one embodiment, the first fitting member 61 and the second fitting member 62 can be connected to the rotating member 11 at the same time, that is, the first fitting member 61 and the second fitting member 62 are sleeved outside the rotating member 11, and the first fitting member 61 and the second fitting member 62 can rotate synchronously with the rotating member 11. At the same time, the guide wheel 20 is arranged between the first fitting member 61 and the second fitting member 62, that is, Figure 17 As shown, the upper portion is a first mating piece 61, the lower portion is a second mating piece 62, and the guide wheel 20 is disposed between the first mating piece 61 and the second mating piece 62. The upper portion of the guide wheel 20 can be mated with the first mating piece 61, and the lower portion of the guide wheel 20 can be mated with the second mating piece 62.

[0128] When the guide wheel 20 engages with the first engaging member 61, the rotating member 11 drives the first engaging member 61 to rotate, which in turn drives the guide wheel 20 to rotate in the first direction. When the guide wheel 20 engages with the second engaging member 62, the rotating member 11 drives the second engaging member 62 to rotate, which in turn drives the guide wheel 20 to rotate in the second direction. When the guide wheel 20 engages with both the first and second engaging members 61, 62, the guide wheel 20 is locked between the first and second engaging members 61, 62, causing the rotating member 11, the first and second engaging members 61, 62, and the guide wheel 20 to stop rotating.

[0129] The first fitting member 61 and the second fitting member 62 can move relative to the guide wheel 20 along the length direction of the rotating member 11, that is, Figure 17As shown, the first and second mating members 61, 62 are capable of vertical movement. The first mating member 61 can engage with the guide wheel 20 by moving downward, and disengage from the guide wheel 20 by moving upward. The second mating member 62 can engage with the guide wheel 20 by moving upward, and disengage from the guide wheel 20 by moving downward. The spacing between the first and second mating members 61, 62 is fixed, ensuring that at least one of the first and second mating members 61, 62 engages with the guide wheel 20.

[0130] In this embodiment, the first matching piece 61 and the second matching piece 62 are sleeved on the rotating piece 11 and rotate synchronously with the rotating piece 11. At the same time, the guide wheel 20 is arranged between the first matching piece 61 and the second matching piece 62, and the first matching piece 61 and the second matching piece 62 are fixed in distance and can move relative to the guide wheel 20, so that the guide wheel 20 can cooperate with at least one of the first matching piece 61 and the second matching piece 62, so that the guide wheel 20 can switch between the first direction and the second direction more conveniently, and when the rotating piece 11 rotates, it will definitely drive the guide wheel 20 to rotate through the first matching piece 61 or the second matching piece 62, thereby preventing the rotating piece 11 from idling and wasting energy.

[0131] Optionally, the reversing assembly 60 further includes a third mating member 63, which is disposed between the first mating member 61 and the second mating member 62, and the guide wheel 20 is fixed to the third mating member 63. When the third mating member 63 engages with the first mating member 61, the first mating member 61 drives the third mating member 63 to rotate in the first direction, and the third mating member 63 also drives the guide wheel 20 to rotate in the first direction. When the third mating member 63 engages with the second mating member 62, the second mating member 62 drives the third mating member 63 to rotate in the second direction, and the bottom mating member also drives the guide wheel 20 to rotate in the second direction. When the third mating member 63 engages with both the first mating member 61 and the second mating member 62, the first mating member 61, the second mating member 62, the third mating member 63, and the guide wheel 20 all stop rotating. Optionally, the third mating member 63 includes, but is not limited to, a cylindrical gear, a bevel gear, etc. In this embodiment, the third mating member 63 is schematically illustrated as a bevel gear.

[0132] Optionally, when the first and second mating members 61, 62 move relative to the guide wheel 20, the guide wheel 20 may remain stationary while the first and second mating members 61, 62 move relative to the guide wheel 20. Alternatively, the first and second mating members 61, 62 may remain stationary while the guide wheel 20 moves relative to the first and second mating members 61, 62. This embodiment is merely schematically described with the guide wheel 20 stationary while the first and second mating members 61, 62 move.

[0133] Please refer to Figure 16-19 , Figure 19This is a schematic diagram illustrating the engagement of the switch protrusion and the reed in one embodiment of the present application. In this embodiment, the reversing assembly 60 further includes a sliding rod 64. The rotating member 11 can drive the sliding rod 64 to rotate synchronously. The first mating member 61 and the second mating member 62 are sleeved and fixed to the sliding rod 64. The sliding rod 64 can slide along its axial direction, thereby engaging the guide wheel 20 with at least one of the first mating member 61 and the second mating member 62.

[0134] As can be seen from the above, the first mating member 61 and the second mating member 62 can move relative to the guide wheel 20. On this basis, the present embodiment can further include a sliding rod 64. The sliding rod 64 is mainly used to cooperate with the rotating member 11, the first mating member 61, and the second mating member 62. The sliding rod 64 can rotate synchronously with the rotating member 11 under the drive of the rotating member 11, and the sliding rod 64 can slide along its axial direction, that is, Figure 17 As shown, the sliding rod 64 can slide up and down. The first matching member 61 and the second matching member 62 are sleeved and fixed on the sliding rod 64, that is, the spacing between the first matching member 61 and the second matching member 62 is fixed, and when the sliding rod 64 slides up and down, the first matching member 61 and the second matching member 62 move synchronously with the sliding rod 64.

[0135] The guide wheel 20 is disposed between the first and second mating members 61, 62. When the sliding rod 64 drives the first and second mating members 61, 62 upward, the second mating member 62 engages with the guide wheel 20, causing the guide wheel 20 to rotate in the second direction. When the sliding rod 64 drives the first and second mating members 61, 62 downward, the first mating member 61 engages with the guide wheel 20, causing the guide wheel 20 to rotate in the first direction.

[0136] In this embodiment, a sliding rod 64 is added to the reversing assembly 60, and the first and second mating members 61 and 62 are fixed to the sliding rod 64. This ensures that the spacing between the first and second mating members 61 and 62 is fixed, and the first and second mating members 61 and 62 move more conveniently relative to the guide wheel 20, thereby reducing the difficulty of operation.

[0137] Alternatively, as Figure 16 、 Figure 18 As shown, the handle assembly 10 includes a housing 12 and a switch 13. The reversing assembly 60 is located within the housing 12. The switch 13 extends through the housing 12 and is connected to a sliding rod 64. The switch 13 can slide up and down manually by the user. When the switch 13 is toggled upward, the sliding rod 64 slides upward in tandem. When the switch 13 is toggled downward, the sliding rod 64 slides downward in tandem. The provision of the switch 13 simplifies the user's operation of switching between the open and closed positions of the umbrella.

[0138] Further optionally, as Figure 19 As shown, the inner wall of the housing 12 further includes a switch protrusion 120. The switch 13 also includes a reed 130, which is disposed within the housing 12. As the switch 13 moves toward one end, toward the guide wheel 20 and engages with the first and second mating members 61 and 62, the switch protrusion 120 gradually abuts against the reed 130, causing it to deform. As the switch 13 continues to move toward the other end, the reed 130 releases its elastic potential energy, pushing the switch 13 in the opposite direction, thereby enabling faster and smoother switching of the switch 13.

[0139] Please refer to Figure 3 、 Figure 20-21 , Figure 20 This is a separate schematic diagram of the reversing assembly and the guide wheel in one embodiment of the present application. Figure 21 This is a schematic diagram of the three-dimensional structure of the switch and the reversing component when they cooperate in another embodiment of the present application.

[0140] In this embodiment, the reversing assembly 60 also includes a third fitting member 63, the first fitting member 61 and the second fitting member 62 are arranged at both ends of the third fitting member 63, and the third fitting member 63 connects the first fitting member 61 and the second fitting member 62, and the guide wheel 20 is arranged between the first fitting member 61 and the second fitting member 62.

[0141] The reversing assembly 60 also includes a reversing member 65, which passes through the first mating member 61, the second mating member 62, and the guide wheel 20. The reversing member 65 is provided with a mating protrusion 650, the first mating member 61 is provided with a first mating groove 610, the second mating member 62 is provided with a second mating groove 620, and the guide wheel 20 is provided with a third mating groove 22. The reversing member 65 can slide along its axial direction, so that the mating protrusion 650 is provided in the third mating groove 22, and at least one of the first mating groove 610 and the second mating groove 620.

[0142] In another embodiment, the reversing assembly 60 further includes a third matching piece 63, and the first matching piece 61 and the second matching piece 62 are respectively disposed at two ends of the third matching piece 63. Figure 3 As shown, the left side is the first matching piece 61, the right side is the second matching piece 62, and the third matching piece 63 is arranged between the first matching piece 61 and the second matching piece 62. The rotating member 11 can drive the third matching piece 63 to rotate, and the third matching piece 63 is connected to the first matching piece 61 and the second matching piece 62 at the same time. In other words, when the third matching piece 63 rotates, it can simultaneously drive the first matching piece 61 and the second matching piece 62 to rotate. The guide wheel 20 is arranged between the first matching piece 61 and the second matching piece 62, that is, Figure 3As shown, the guide wheel 20 is disposed between the first matching member 61 and the second matching member 62 .

[0143] In this embodiment, the reversing assembly 60 further includes a reversing member 65, which passes through the first mating member 61, the guide wheel 20, and the second mating member 62 in sequence. In other words, the first mating member 61, the second mating member 62, and the guide wheel 20 are all hollow structures, and the reversing member 65 can pass through the first mating member 61, the guide wheel 20, and the second mating member 62 in sequence. The surface of the reversing member 65 is provided with a mating protrusion 650, the inner wall of the first mating member 61 is provided with a first mating groove 610, the inner wall of the second mating member 62 is provided with a second mating groove 620, and the inner wall of the guide wheel 20 is provided with a third mating groove 22. The reversing member 65 can slide along its axial direction, that is, Figure 21 As shown, the reversing member 65 can slide left and right.

[0144] When the diverter 65 slides to the left, the mating protrusion 650 can be disposed in the first mating groove 610 and the third mating groove 22. That is, the first mating member 61 drives the diverter 65 to rotate, and the diverter 65 drives the guide wheel 20 to rotate synchronously, that is, the guide wheel 20 rotates in the first direction. When the diverter 65 slides to the right, the mating protrusion 650 can be disposed in the second mating groove 620 and the third mating groove 22. That is, the second mating member 62 drives the diverter 65 to rotate, and the diverter 65 drives the guide wheel 20 to rotate synchronously, that is, the guide wheel 20 rotates in the second direction. When the mating protrusion 650 is simultaneously disposed in the first mating groove 610, the second mating groove 620, and the third mating groove 22, the diverter 65 engages the first mating member 61 and the second mating member 62, thereby causing the first mating member 61, the second mating member 62, the third mating member 63, and the guide wheel 20 to be stationary.

[0145] In this embodiment, the third mating member 63 is provided for the reversing assembly 60, so that the third mating member 63 simultaneously drives the first mating member 61 and the second mating member 62 to rotate. Furthermore, the provision of the reversing member 65 facilitates the guide wheel 20 to engage with at least one of the first mating member 61 and the second mating member 62, thereby reducing the difficulty of operation.

[0146] Optionally, the umbrella handle assembly 10 includes a housing 12 and two switches 13, the reversing member 65 passes through the housing 12 and the two ends of the reversing member 65 are respectively fixed to the two switches 13. Figure 21 As shown, when the left switch 13 is pressed, the reversing rod slides to the right, and the right switch 13 pops up. When the right switch 13 is pressed, the reversing rod slides to the left, and the left switch 13 pops up. The arrangement of the switch 13 reduces the difficulty for the user to switch between the open and closed states of the umbrella.

[0147] Please refer to Figure 22 , Figure 22The diagram is a schematic diagram of the three-dimensional structure of the ratchet and pawl in one embodiment of the present application. In this embodiment, the umbrella handle assembly 10 further includes a ratchet 14, a pawl 15, and a housing 12. The ratchet 14 is disposed within the housing 12 and connected to the rotating member 11. The pawl 15 is fixed to the housing 12. When the ratchet 14 rotates in the first direction, it can rotate relative to the pawl 15. When the ratchet 14 rotates in the second direction, the pawl 15 can limit the ratchet 14, allowing it to rotate only in the first direction.

[0148] In this embodiment, the umbrella handle assembly 10 further includes a ratchet 14, a pawl 15, and a housing 12. The housing 12 primarily houses the various components within the umbrella handle assembly 10. The ratchet 14 primarily cooperates with the pawl 15. The ratchet 14 is connected to the rotating member 11, meaning that the ratchet 14 and the rotating member 11 rotate in the same direction. The pawl 15 is fixed to the housing 12, meaning that the pawl 15 and the housing 12 cannot rotate with each other. When the ratchet 14 rotates in a first direction, the ratchet 14 can rotate relative to the pawl 15, meaning that the pawl 15 allows the ratchet 14 to rotate in the first direction. When the ratchet 14 rotates in a second direction, the pawl 15 limits the ratchet 14, thereby preventing the ratchet 14 from rotating in the second direction. Therefore, the ratchet 14 can only rotate in the first direction. In this embodiment, the arrangement of the ratchet 14 and the pawl 15 allows the ratchet 14 to rotate only in the first direction, thus limiting its rotational direction.

[0149] Optionally, there are two pawls 15 , which are respectively arranged on both sides of the ratchet 14 , so that the engagement effect of the pawl 15 when engaging the ratchet 14 is better and more stable.

[0150] Please refer to Figure 23-25 , Figure 23 This is a schematic diagram of the three-dimensional structure of the rotating member and the ratchet when they cooperate with the rotating part in one embodiment of the present application. Figure 24 for Figure 23 The cross-sectional schematic diagram of the rotating part is shown. Figure 25 for Figure 23 The schematic diagram shown is when the elastic member cooperates with the rotating member and the housing.

[0151] In this embodiment, the automatically opening and closing folding umbrella 1 further includes a rotating portion 70, which includes a shell 72 and an elastic member 71. The ratchet 14 is fixedly connected to the shell 72, and one end of the elastic member 71 is connected to the shell 72, and the other end is connected to the rotating member 11. When the shell 72 rotates along the first direction, the elastic member 71 drives the rotating member 11 to rotate along the first direction.

[0152] When the automatic opening and closing folding umbrella 1 is in the expanded state or the retracted state, the rotating member 11 stops rotating, and the shell 72 can continue to rotate in the first direction, so that the elastic member 71 is deformed to store elastic potential energy. When the automatic opening and closing folding umbrella 1 switches between the expanded state and the retracted state, the elastic member 71 releases the elastic potential energy to cause the rotating member 11 to rotate.

[0153] In this embodiment, the automatically opening and closing folding umbrella 1 further includes a rotating portion 70, which is primarily used to manually rotate the rotating portion 70. The rotating portion 70 includes a housing 72 and an elastic member 71. The ratchet 14 is fixed to the housing 72, meaning that the housing 72 and the ratchet 14 can only rotate in a first direction. One end of the elastic member 71 is connected to the housing 72, and the other end is connected to the rotating member 11. When the housing 72 is manually rotated in the first direction, the elastic member 71 can drive the rotating member 11 to rotate in the first direction as well. The elastic member 71 includes, but is not limited to, elastic components such as a volute spring, a coil spring, and a leaf spring. In this embodiment, the elastic member 71 is schematically illustrated as a volute spring.

[0154] At the same time, when the automatic opening and closing folding umbrella 1 is in the expanded or retracted state, the transmission assembly 30 is stretched to its limit, meaning that the guide wheel 20 can no longer pull the transmission assembly 30. At this point, the guide wheel 20 is stationary, causing the rotating member 11 that cooperates with the guide wheel 20 to also be stationary. At this point, the housing 72 can continue to be manually rotated. Because the rotating member 11 cannot rotate, and the housing 72 is connected to the ratchet 14 and cannot rotate in the second direction, i.e., reverse rotation, the elastic member 71 can deform, thereby storing elastic potential energy, which can only be released through the rotation of the rotating member 11. When the automatic opening and closing folding umbrella 1 switches between the expanded and closed states, the rotating member 11 can continue to rotate using the elastic potential energy stored in the elastic member 71, thereby causing the automatic opening and closing folding umbrella 1 to expand or close.

[0155] In this embodiment, the rotating part 70 provides power to the rotating member 11. At the same time, the rotating part 70 has an elastic member 71 that can store elastic potential energy. That is, after the elastic member 71 is manually deformed to store elastic potential energy, the elastic member 71 can automatically release the elastic potential energy to rotate the rotating part 70, thereby realizing the automatic expansion and closing of the automatic opening and closing folding umbrella 1, reducing the user's operating difficulty.
