[0036] The handrail assembly 100 includes a housing 110, a rope winding mechanism 400, a lifting mechanism 600, and a power switching mechanism 500. The housing 110 typically includes two opposing, assembled outer shell bodies 111 and upper and lower covers 112. The two outer shell bodies 111 are joined together to form an assembly cavity. The rope winding mechanism 400 and the lifting mechanism 600 are both installed in the assembly cavity. Some components of the power switching mechanism 500 are also installed in the assembly cavity. The power switching mechanism 500 is used to achieve… Power switching input to the rope winding mechanism 400 or the lifting mechanism 600; when the power switching mechanism 500 switches to drive the rope winding mechanism 400, the power switching mechanism 500 realizes power input and transmits it to the rope winding mechanism 400, and the rope winding mechanism 400 realizes the opening and closing of the umbrella frame 700; when the power switching mechanism 500 switches to drive the lifting mechanism 600, the power switching mechanism 500 realizes power input and transmits it to the lifting mechanism 600, and the lifting mechanism 600 drives the handrail assembly to move up and down along the umbrella column 200.

[0037] In conjunction with the above, this embodiment optimizes the handrail assembly 100 by integrating the rope winding mechanism 400 and the lifting mechanism 600 into the handrail assembly 100. In particular, a power switching mechanism 500 is added, which can realize the power switching input between the rope winding mechanism 400 and the lifting mechanism 600. The handrail assembly 100 can be raised or lowered or the umbrella frame 700 can be opened or closed by cranking the hand, without the need for manual operation by the user, thus improving the convenience of operation.

[0038] In its specific structure, the power switching mechanism 500 includes a power transmission assembly 510 and a switching assembly 520. The power transmission assembly 510 includes an input shaft 511, a first transmission gear 512, and a second transmission gear 513. The input shaft 511 drives either the first transmission gear 512 or the second transmission gear 513 to rotate.

By optimizing the use of the switching component 520, the input shaft 511 can switch between the first transmission gear 512 or the second transmission gear 513 when power is input, so that the same power input can drive the rope winding mechanism 400 or the lifting mechanism 600.

[0039] In summary, the switching assembly 520 includes a control element 521, a control shaft 522, a switching arm 523, a clutch fork 524, a fork seat 525, and a clutch locking arm 526. The control element 521 and the control shaft 522 can be an integral structure or separate structures. The control shaft 522 extends to the outside of the housing 110, while the control element 521 is typically located outside the housing 110. The control element 521 drives the control shaft 522 to rotate. The control element 521 can be a rotary knob, trigger, handle, or other operating component. The control shaft 522 drives the switching arm 523 to move. By operating the control element 521, the control shaft 522 is rotated, causing the switching arm 523, which is located at the inner end of the control shaft 522, to deflect, thus switching the clutch. The other end of arm 523 moves accordingly, and switching arm 523 is used to drive the movement of clutch shift fork 524 and clutch locking arm 525. Clutch shift fork 524 is used to drive the position of shift fork seat 526 to move. Shift fork seat 526 is used to achieve transmission lock with the first transmission gear 512 or the second transmission gear 513. Through the reciprocating operation of control member 521, the clutch shift fork 524 can eventually drive shift fork seat 526 to achieve position exchange, thereby achieving transmission lock or separation between shift fork seat 526 and the first transmission gear 512, or transmission lock or separation between shift fork seat 526 and the second transmission gear 523, and simultaneously driving clutch locking arm 525 to achieve position exchange, realizing the locking and disengagement of clutch locking arm 525 with lifting mechanism 600.

[0040] In its specific structure, the input shaft 511 includes an input section 5111, a first gear mating section 5112, a sliding groove section 5113, and a second gear mating section 5114. The sliding groove section 5113 is fitted with a shift fork seat 526. A shift fork groove 5261 is provided inside the shift fork seat 526. One end of the clutch shift fork 524 is fitted with the shift fork groove 5261. The clutch shift fork 524 can move the shift fork seat 526 along the sliding groove section 5113 by moving, thereby locking the transmission of the first transmission gear 512 or the second transmission gear 513. The first transmission gear 512 is sleeved and installed on the first gear mating section 5112, and the second transmission gear 513 is sleeved and installed on the second gear mating section 5114. The first transmission gear 512 and the first gear mating section... 5112 is a free-running engagement, and the second transmission gear 513 and the second gear engagement part 5114 are also free-running engagements. The sliding groove part 5113 is provided with a spline groove, and the shift fork seat 526 is correspondingly engaged with a spline tooth, so that the shift fork seat 526 can move axially relative to the sliding groove part 5113. The clutch shift fork 524 engages with the shift fork groove 5261. The movement of the clutch shift fork 524 drives the shift fork seat 526 to move axially. The first transmission gear 512 and the second transmission gear 513 are located at both ends of the shift fork seat 526. The shift fork seat 526 can move left and right to lock the first transmission gear 512 or the second transmission gear 513, so that the rotation of the input shaft 511 can drive the rotation of the first transmission gear 512 or the second transmission gear 513.

[0041] In conjunction with the above, the shift fork seat 526 is provided with a first locking tooth portion 5262 and a second locking tooth portion 5263 at both ends, and a first pair of teeth 5121 is provided on the side of the shift fork seat adjacent to the first transmission tooth 5122, and a second pair of teeth 5131 is provided on the side of the shift fork seat adjacent to the second transmission tooth 5131. When the shift fork seat 526 moves so that the first locking tooth portion 5262 engages with the first pair of teeth 5121, the input shaft 511 drives the first transmission tooth 512. When the shift fork seat 526 moves so that the second locking tooth portion 5263 engages with the second pair of teeth 5131, the input shaft 511 drives the second transmission tooth 513.

[0042] The clutch fork 524 is provided with an abutment part 5241, which is sleeved on the locking arm pin 527. The clutch locking arm 525 cooperates with the locking arm pin 527. As the clutch fork 524 moves, the abutment part 5241 can slide along the locking arm pin 527. One end of the abutment part 5241 abuts against the clutch locking arm 525, and the other end of the clutch locking arm 525 is equipped with a first return spring 528. In other equivalent embodiments, the position of the abutment part 5241 can be set on the clutch locking arm 525, and the positions can be interchanged. When the switching arm 523 drives the clutch fork 524 to move, the abutment part 5241 moves, and the abutment part 5241 cooperates with the clutch locking arm 525, so that the other end of the clutch locking arm 525 is locked with the lifting mechanism 600. In the specific structure In the process, the switching arm 523 drives the clutch fork 524 to move, which in turn drives the contact part 5241 to move. Normally, the contact part 5241 pushes against the clutch locking arm 525, compressing the first return spring 528. The clutch locking arm 525 moves in the same direction as the contact part 5241, resulting in a lateral movement of the clutch locking arm 525 as a whole. When the switching arm 523 drives the clutch fork 524 to return to its original position, the contact part 5241 separates from the clutch locking arm 525. Since the other end of the clutch locking arm 525 contacts the first return spring 528, the first return spring 528 returns to its original position, pushing the clutch locking arm 525 to move away from the contact part 5241. The return of the first return spring 528 drives the clutch locking arm 525 to move laterally as a whole.

[0043] In one preferred embodiment, a limiting seat 140 is provided inside the housing 110. The upper part of the limiting seat 140 has a guide groove 130. The guide groove 130 structure on the limiting seat 140 restricts the movement of the limiting plate 5232. The switching arm 523 includes a switching fork 5231 located at the upper part and a limiting plate 5232 located at the lower part. The switching fork 5231 is used to cooperate with the clutch fork 524. The limiting plate 5232 can swing left and right along the guide groove 130. In other embodiments, a limiting seat 140 is provided inside the housing 110. The upper part of the limiting seat 140 has a guide groove 130. The switching arm 523 includes a switching fork 5232 located at the upper part. 1. A limiting plate 5232 is located at the bottom. The switching fork 5231 is used to cooperate with the clutch fork 524. The limiting plate 5232 can swing left and right along the guide groove 130. The limiting seat 140 is located on one side of the guide groove and is a split structure. The limiting plate 5232 moves along the guide groove 130, and the limiting seat 140 is used to limit the movement position of the limiting plate 5232. The structure of the limiting seat 140 is optimized so that after the control member 521 drives the control shaft 522 to rotate, it drives the switching arm 523 to have a corresponding switching stroke, which is used to cooperate with the shifting stroke of the clutch fork 524. This facilitates the shift fork seat 526 to achieve the movement and cooperation of both ends, improving the switching accuracy and operation stability.

[0044] In the specific structure, the rope winding mechanism 400 includes a rope winding tooth 410, a rope winding shaft 430, and a rope winding wheel 420. The rope winding tooth 410 and the rope winding wheel 420 are fitted onto the rope winding shaft 430. When the first transmission tooth 512 is in the transmission state with the rope winding mechanism 400, the rope winding tooth 410 meshes with the first transmission tooth 512. The rope winding tooth 410 can drive the rope winding shaft 430 to rotate, and the rope winding shaft 430 drives the rope winding wheel 420 to rotate. The rope winding wheel 420 is usually fitted with the paracord to realize the winding or unwinding of the paracord. The other end of the paracord extends to the umbrella frame 700, and the opening and closing of the umbrella frame 700 is realized by winding or unwinding the paracord.

[0045] In the specific structure, the lifting mechanism 600 includes a lifting gear 610, a third transmission gear 620, and a lifting transmission shaft assembly 630. The lifting gear 610 and the third transmission gear 620 are installed in the lifting transmission shaft assembly 630. When the second transmission gear 513 is in the transmission state with the lifting mechanism 600, the second transmission gear 513 meshes with the third transmission gear 620. The third transmission gear 620 drives the lifting transmission shaft assembly 630 to rotate. The lifting transmission shaft assembly 630 drives the lifting gear 610 to drive. The lifting gear 610 cooperates with the rack 210 in the column 200 to realize the up and down movement of the handrail assembly 100 along the umbrella column 200.

[0046] Preferably, the lifting drive shaft assembly 630 includes a first drive shaft body 631, a second drive shaft body 632, and a second return spring 633 located between the first drive shaft body 631 and the second drive shaft body 632. The first drive shaft body 631 and the second drive shaft body 632 are mated together. One end of the clutch locking arm 525 is sleeved on the first drive shaft body 631 and cooperates with the second return spring 633. A locking shaft 5251 is provided on the clutch locking arm 525, which is used to lock in correspondence with the locking groove 611 in the lifting gear 610. The clutch locking arm 525 structure is optimized. By moving the clutch locking arm 525, the locking shaft 5251 and the locking groove 611 can be locked or separated. Specifically, when the lifting mechanism 600 is in the transmission state, the locking shaft 5251 and the locking groove 611 are separated. When the lifting mechanism 600 is in the non-transmission state, the locking shaft 5251 and the locking groove 611 are locked, so that the lifting tooth 610 is locked by the clutch locking arm 525, preventing the lifting tooth 610 from rotating, and realizing the height locking of the handrail assembly 100 on the umbrella column 200.

[0047] In summary, the specific operating principle of this embodiment is as follows: When the user needs to switch to the lifting mechanism 600 to move the handrail assembly 100 up and down along the umbrella column 200, the user operates the control component 521, causing the control shaft 522 to rotate, which in turn moves the switching arm 523. The switching arm 523 then moves the clutch fork 524, causing it to move. The contact part 5241 on the clutch fork 524 abuts against the clutch locking arm 525, thereby moving the clutch locking arm 525. The clutch locking arm 525 moves along the locking pin 527, compressing the first return spring 528. After the clutch locking arm 525 shifts laterally, the lower locking shaft 5251 separates from the locking groove 611. At the same time, the clutch fork 524... The movement of 4 drives the shift fork seat 526 to move, and the shift fork seat 526 docks and locks with the second transmission gear 513, realizing the locking of the second locking tooth part 5263 and the second pair of teeth part 5131. The user shakes the hand crank 120, which drives the input shaft 511 to rotate. The input shaft 511 drives the second transmission gear 513 to rotate, and the second transmission gear 513 drives the third transmission gear 620 to rotate. With the rotation of the third transmission gear 620, the lifting transmission shaft assembly 630 is driven to rotate, thereby driving the lifting tooth 610 to rotate. With the cooperation of the lifting tooth 610 and the rack 210, the handrail assembly 100 is driven to move along the umbrella column 200. The direction of rotation of the hand crank 120 is controlled to achieve upward or downward movement.

[0048] When the user needs to switch to umbrella opening / closing operation, the user operates the control component 521, causing the control shaft 522 to rotate, which in turn moves the switching arm 523. The switching arm 523 then moves the clutch fork 524. The contact part 5241 on the clutch fork 524 is usually separated from the clutch locking arm 525. Due to the reset action of the first return spring 528, the clutch locking arm 525 moves along the locking pin 527. After the clutch locking arm 525 moves laterally, the lower locking shaft 5251 locks with the locking groove 611, achieving position locking. The armrest assembly 100 is then fixed to the umbrella column 200. At the same time, the clutch fork 524 is continuously moved, causing the clutch fork 524 to move and drive the fork seat 526 to move. The fork seat 526 engages and locks with the first transmission gear 512, achieving the locking of the first locking tooth part 5262 and the first pair of teeth part 5121. The user shakes the hand crank 120, which drives the input shaft 511 to rotate. The input shaft 511 drives the first transmission gear 512 to rotate, which drives the rope winding tooth 410 to rotate. As the rope winding tooth 410 rotates, it synchronously drives the rope winding shaft 430 and the rope winding wheel 420 to rotate, thereby driving the umbrella rope to wind or unwind, realizing the opening and closing of the umbrella frame 700.

[0049] 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.
