[0002] In the field of sunshade umbrellas, despite continuous advancements in product design and technology, some technical shortcomings and areas for improvement still exist. Currently, sunshade umbrellas generally use a slider that is manually pushed or cranked to raise and lower, thereby changing the angle of the umbrella canopy. At the end of the slider or crossbar, a crank or lever is used to rotate the crossbar, changing the angle of the umbrella canopy. At the end of the slider or crossbar, a crank drives a spool to open and close the umbrella canopy. When the umbrella canopy is relatively large, these three manual operations are quite laborious.

[0034] Please see Figure 2 As shown, in a preferred embodiment of this utility model, the slider is composed of slider A 23-1 and slider B 23-2, which are fitted together on the column 1. The opening is provided on slider B 23-2, and the first motor 21 is fixed on slider A 23-1 by motor bracket 22.

[0035] In a preferred embodiment of this utility model, the gear transmission assembly includes a spur gear 26 that meshes with a rack 27 on the column 1. The spur gear 26 is also fixed to a first worm gear 242 of the transmission 24. The output shaft of the first motor 21 is fixed to one end of the first worm 241 of the transmission 24, and the other end of the first worm 241 is fixed to a first bevel gear 251. The first bevel gear 251 meshes perpendicularly with a second bevel gear 252. The second bevel gear 252 drives the first bevel gear 251 to rotate. The first bevel gear 251 drives the first worm 241 and the first worm gear 242 to rotate. The first worm gear 242 drives the spur gear 26 to rotate.

[0036] In a preferred embodiment of this utility model, a first sensing magnet 28 is installed on the spur gear 26, and a first Hall circuit board 29 is installed below it. The first Hall circuit board 29 is in contact with the gearbox 24. The first sensing magnet 28 and the first Hall circuit board 29 generate a sensing magnetic field, which drives the slider to slide on the column 1.

[0037] In a preferred embodiment of this utility model, the slider B 23-2 is provided with an opening for inserting a first hand crank 201 or a first plug 203, and the second bevel gear 252 is fixed to the first crank shaft 202 of the first hand crank 201; and

In electric mode, the first plug 203 is installed on the slider. In manual mode, the first plug 203 is removed, the first hand crank 201 is inserted, and the hand crank is rotated to achieve the up and down sliding of the slider.

[0040] In a specific embodiment of this utility model, the lifting and lowering steps of the slider assembly will be described below:

[0041] 1. Electric Mode: The first motor 21 provides power, which is amplified by the gearbox 24 and transmitted to the spur gear 26. The spur gear 26 meshes with the rack 27 on the column 1, thereby raising or lowering the slider. The gearbox 24 has a self-locking function. When the gearbox 24 stops working, the slider remains stationary because the spur gear 26 is engaged with the rack 27 on the column 1.

[0042] 2. Manual Mode: Remove the first plug 203 from the crank handle and insert the first hand crank handle 201 into the gear shaft. When the crank handle is manually turned, the second bevel gear 252 rotates, driving the first bevel gear 251 to rotate. The first bevel gear 251 drives the first worm gear 242 and the first worm 241 within the gearbox 24 to rotate, and the first worm gear 242 drives the spur gear 26 to rotate. The spur gear 26 meshes with the rack 27, thereby enabling the slider to move up and down. The gearbox 24 has a self-locking function; when the gearbox 24 stops working, the slider remains stationary because the spur gear 26 is engaged with the rack 27 on the column 1.

[0043] 3. Electric elevation angle: When the umbrella is fully open, operate the remote control 204 to move the slider downwards. When the maximum elevation angle of approximately 40° is reached, the slider stops, and the electric elevation angle adjustment is completed. In practical applications, the remote control 204 can be positioned at any position below the maximum to obtain different umbrella elevation angles.

[0044] Please see Figure 3 As shown, a crossbar rotating assembly 6 is provided on the crossbar 3, which cooperates with the motor rotating assembly. Under the control of the photosensitive switch, the crossbar rotating assembly 6 drives the umbrella surface to rotate and limit its position. The outside of the crossbar rotating assembly 6 is a motor housing 30. The motor housing 30 is provided with an opening for installing a second hand crank 301 or a locking pin 302.

[0045] In a preferred embodiment of this utility model, the motor rotation assembly includes a second motor 31, the output shaft of the second motor 31 is fixed to a first gear 32, the first gear 32 meshes with one side of a second gear 33, the other side of the second gear 33 meshes with a third gear 34, the third gear 34 also contacts a second worm 35, the second worm 35 is also provided with a crank handle mating hole 36, the crank handle mating hole 36 is used to fix the second hand crank 301, or the locking pin 302 is engaged on the second worm 35, and the second worm 35 is also used to drive the second worm wheel 39 thereon to rotate.

[0046] In a preferred embodiment of the present invention, both the third gear 34 and the second worm gear 35 are provided with steel ball grooves 313 for accommodating steel balls 37.

[0047] When the opening is inserted into the retaining pin 302, the third gear 34 engages with the second worm gear 35, and the retaining pin 302 inserts the steel ball 37 into the steel ball groove 313 of the third gear 34; or

[0048] When the opening is inserted into the second hand crank 301, a strong magnet 38 is embedded in the second hand crank 301. The strong magnet 38 attracts the steel ball 37 into the steel ball groove 313 of the second worm 35, thereby separating the third gear 34 from the second worm 35.

[0049] In a preferred embodiment of this utility model, the motor housing 30 is composed of a first housing A 311 and a first housing B 312. The opening is provided on the first housing A 311, and the first housing A 311 is engraved with three scales: a left turn limit point, a reset 0 point, and a right turn limit point. The crossbar rotation assembly 6 moves under the control of a photosensitive switch and stops rotating when it reaches the left turn limit point or the right turn limit point.

[0050] like Figure 3 As shown, the output shaft of the second motor 31 is fixed to the first gear 32. The second gear 33 meshes with the first gear 32 and the third gear 34, serving as a transmission mechanism. The third gear 34 has a steel ball groove 313, which engages with the second worm gear 35. The surface of the second worm gear 35 also has a steel ball groove 313. The engagement and disengagement of the two steel balls are achieved through their protrusion and depression movements.

In electric mode, the retaining pin 302 is fixed inside the second worm gear 35, and the second worm gear 35 engages with the third gear 34. In manual mode, the retaining pin 302 is removed, and the second hand crank 301 is inserted into the second worm gear 35. The crank handle shaft has a strong magnet 38 embedded in it, which attracts the steel ball 37 into the steel ball groove 313 of the second worm gear 35, thus separating the second worm gear 35 from the third gear 34. The first outer casing A 311 is engraved with three markings: the left turn limit point, the reset 0 point, and the right turn limit point. Under the control of the light-sensitive switch, the rotation will stop if it reaches the limit point.

[0051] In practical applications, the operation steps of the above-mentioned crossbar rotation assembly 6 are as follows:

[0052] 1. Electric Mode: The second motor 31 provides power, driving the first gear 32 to rotate. The torque is then transmitted to the third gear 34 via the second gear 33. At this time, the locking pin 302 is inserted into the second worm 35, and the steel ball 37 is lifted above the surface of the second worm 35 and enters the groove of the third gear 34. The second worm 35, the two steel balls 37, and the third gear 34 are interconnected and rotate simultaneously. The third gear 34 drives the second worm 35 to rotate, and the second worm 35 drives the second worm wheel 39 to rotate, thereby rotating the crossbar 3 and causing the umbrella to tilt to the left and right.

[0053] 2. Manual Mode: Remove the locking pin 302 and insert the second hand crank 301 into the second worm gear 35. The hand crank has a strong magnet 38 embedded within it, which attracts the steel ball 37 into the steel ball groove 313 of the second worm wheel 39. The steel ball 37 is below the surface of the second worm gear 35, at which point the second worm gear 35 is separated from the gear. Manually rotate the second hand crank 301, causing the second worm gear 35 to rotate. The second worm gear 35 drives the second worm wheel 39 to rotate, thus rotating the crossbar 3, which in turn causes the umbrella to tilt to the left and right.

[0054] Please see Figure 4 As shown, in a preferred embodiment of this utility model, the motor rotation assembly provided on the upper nest assembly 5 includes a third motor 51. The third motor 51 is disposed on the upper nest seat 53 including the upper nest cover 52 and sealed by the second outer shell A 501 and the second outer shell B 502.

The first induction magnet mounting holes 571 are used to install second induction magnets 572, and the Hall effect sensing points are used to perform magnetic field sensing with the second Hall circuit board 58 disposed below the first spool 57.

[0055] In a preferred embodiment of this utility model, a fixing plate C 503 is provided between the third motor 51 and the gearbox 54, and fixing plates B 504 and A 505 are respectively provided on both sides of the gearbox 54. The first spool 57 is provided on the fixing plate B 505, and an umbrella cord is attached to the first spool 57. The opening and closing of the umbrella canopy is achieved by retracting and extending the umbrella cord.

[0056] In practical applications, the output shaft of the third motor 51 is connected to the third worm gear 55 of the gearbox 54, and the first spool 57 is connected to the worm wheel 56 of the gearbox 54. A parasol line is attached to the first spool 57, and the opening and closing of the umbrella can be controlled by extending and retracting the parasol line. The actual operating steps are as follows:

[0057] When the umbrella opens, the third motor 51 rotates forward, driving the gearbox 54 and the first spool 57 to rotate, tightening the canopy and opening the umbrella. Once the umbrella is fully open, the third motor 51 stops. The gearbox 54's self-locking function keeps the umbrella open, and the third motor is not subjected to stress, protecting and improving its stability and lifespan. When closing the umbrella, the third motor 51 rotates in reverse, and the umbrella closes using its own weight. The first spool 57 has multiple Hall effect sensors; the second Hall effect circuit board 58 is located below the first spool 57. When the third motor 51 drives the gearbox 54 to rotate, and the gearbox 54 drives the first spool 57 to rotate, the second Hall effect circuit board 58 records the number of rotations. When the set number of rotations is reached, the umbrella stops opening or closing.
