For the convenience of description below, the direction of the umbrella handle is defined as down, and the direction of the upper nest is defined as up.

[0047] The present invention provides an automatic umbrella that can be manually or electrically opened and automatically retracted. Its main operating principle is to drive the extension or folding of a link linear motion mechanism by manual or electric power to achieve the opening and closing of the umbrella. Manual opening and closing of the umbrella is mainly applied when there is no electricity; electric opening and closing of the umbrella is mainly applied when there is a power supply.

[0048] As Figure 1 , it is a schematic structural diagram of the automatic umbrella in the opened state; Figure 2 is an exploded view of the umbrella; the automatic umbrella includes an umbrella handle 600, a multi-section umbrella rod sleeved thereon, including a first section rod 110, a second section rod 120, and a third section rod 130. A top nest 150 is fixed to the top of the third section rod 130, and a bottom nest 140 is sleeved on the umbrella rod and slides on the umbrella rod. A pressing block 200 is fixed to the bottom nest 140. The umbrella skeleton assembly 700 supports the folding and unfolding of the umbrella surface. (For simplicity of the view, a set of umbrella skeleton assemblies are shown in the figure, and the umbrella surface is not shown). The umbrella skeleton assembly 700 includes a first pull rod 710, a first support rod 720, a first connecting bone 730, a second connecting bone 740, a third connecting bone 750, and a fourth connecting bone 760. One end of the first pull rod 710 is hinged to the top nest, and the other end is hinged to a three-way joint fixed to the first support rod 720; one end of the first support rod 720 is hinged to the bottom nest, and the other end is hinged to a three-way joint fixed to the second connecting bone 740; one end of the first connecting bone 730 is hinged to a three-way joint fixed to the first pull rod 710, and the other end is hinged to one end of the second connecting bone 740; one end of the second connecting bone 740 is hinged to the first connecting bone 730, and the other end is hinged to one end of the fourth connecting bone 760; one end of the third connecting bone 750 is hinged to a three-way joint fixed to the first connecting bone 730, and the other end is hinged to one end of the fourth connecting bone 760. ( Figure 1 ). The scissor link mechanism 300 is disposed inside the umbrella rod. The scissor link mechanism 300 includes a plurality of links and a plurality of scissor units formed by these links, and each scissor unit is sequentially hinged. On the first scissor unit, there are a link 303 and a link 304, and it also includes a first end fixed hinge pin 301 and a first end movable hinge pin 302. The first end fixed hinge pin is inserted into the fixed hinge pin hole 600.5 of the umbrella handle 600 and rotates in the hinge pin hole 600.5; both ends of the first end movable hinge pin are in the hinge pin chute 600.6 of the umbrella handle 600 and reciprocate linearly in the hinge pin chute 600.6. The last scissor unit of the scissor link mechanism 300 is composed of a link 320 and a link 321, and it also includes a last end fixed hinge pin 330 and a last end movable hinge pin 331. The last end fixed hinge pin 330 is inserted into the pressing block hinge pin hole 200.1, and the last end movable hinge pin 331 passes through the pressing block hinge pin slot 200.2 of the pressing block 200 and reciprocates linearly in the pressing block hinge pin slot ( Figure 4). The middle hinge pin 311 is inserted into the pin hole in the middle of the scissor unit composed of the connecting rod E309 and the connecting rod F310. Both ends of the middle hinge pin 311 pass through the second-section rod chute 120.1. ( Figure 5 ). The plane link mechanism composed of the parachute-opening handle 380 and the parachute-opening handle accessory 381 and the connecting rod R307 on the scissor link mechanism 300 can achieve the extension of the scissor link mechanism by pressing the parachute-opening handle 380. ( Figure 8 、 Figure 11 ). The plane link mechanism composed of the parachute-closing handle 390 and the parachute-closing handle accessory 391 and the connecting rod A305 on the scissor link mechanism 300 can achieve the folding of the scissor link mechanism 300 by pressing the parachute-closing handle 390. ( Figure 8 、 Figure 11 ). The parachute-opening handle 380 and the parachute-closing handle 390 are used when the battery is out of power or the rechargeable mobile power source 630 is not connected. By pressing the parachute-opening handle 380 or the parachute-closing handle 390, the linear motion mechanism of the connecting rod can be extended or contracted to achieve parachute opening and closing. The motor 400 is fixed inside the umbrella handle 600, and the power of the motor is supplied by the battery one 440, the battery two 450, or the rechargeable mobile power source 630. The rechargeable mobile power source 630 is inserted into the external power interface 600.7 of the umbrella handle 600 through the power connection line 630.1. The positive terminal 600.8 of the umbrella handle 600 is connected to the positive pole of the rechargeable mobile power source and the positive pole of the battery, and the negative terminal 600.9 is connected to the negative pole of the rechargeable mobile power source and the negative pole of the battery. ( Figure 3 ). When the rechargeable mobile power source 630 is connected to supply power, the battery one 440 and the battery two 450 are also charged. A turntable 410 is installed on the motor shaft 400.1. When the motor 400 rotates, the turntable 410 rotates with the motor shaft 400.1. The first-end movable hinge pin 302 of the scissor link mechanism 300 that reciprocates linearly in the hinge pin chute 600.6 of the umbrella handle 600 also passes through the turntable groove 410.1 of the turntable 410. When the turntable 410 rotates, it drives the first-end movable hinge pin 302 to rotate. The center position of the first-end movable hinge pin 302 rotating with the turntable 410 changes in the turntable groove 410.1 to keep the first-end movable hinge pin 302 making a linear sliding motion in the hinge pin chute 600.6 of the umbrella handle 600. ( Figure 6 、 Figure 7 ). The boat-shaped switch SB500 is the start switch for the opening and closing of the automatic umbrella. It is controlled by the parachute-opening limit switch S2, the parachute-closing limit switch S1, the intermediate relay KA1, and the intermediate relay KA2.

[0049] Electric parachute-opening process: ( Figure 6 、 Figure 7). The scissor link mechanism 300 is in a folded state. The first-end movable hinge pin 302 moves within the hinge pin chute 600.6 of the umbrella handle 600 to push up the handle 510.4 of the umbrella closing limit switch S1-510, causing the normally closed contact 510.3 of the umbrella closing limit switch S1-510 to disconnect from the common terminal 510.1. After the umbrella closing limit switch S1-510 is triggered, when the rocker switch SB500 is pressed again to start the umbrella closing operation, the umbrella does not move ( Figure 12 、 Figure 13 ).

[0050] Electrical control part: ( Figure 12 、 Figure 13 ). When the upper end of the rocker switch SB 500 is pressed, the umbrella opening operation is started. The normally open contact 500.2 of the rocker switch SB 500 conducts with the common terminal 500.1, and the normally closed contact 500.3 of the rocker switch SB500 disconnects from the common terminal 500.1. The positive current of the power supply provided by the battery or rechargeable mobile power supply 630 flows through the rocker switch SB-500, the common terminal 520.1 and the normally closed contact 520.3 of the umbrella opening limit switch S2-520, and reaches the positive pole 540.7 of the intermediate relay KA2-540. The negative pole 540.8 of the intermediate relay KA2-540 is connected to the negative pole of the battery or rechargeable mobile power supply. The coil of the intermediate relay KA2-540 is energized, and the normally open contact 540.2 of the intermediate relay KA2-540 closes and conducts with the common terminal 540.1, and another pair of normally open contacts 540.5 closes and conducts with the common terminal 540.4. The positive current provided by the battery or rechargeable mobile power supply 630 flows through the common terminal 540.4 and the normally open contact 540.5 of the intermediate relay KA2-540 and reaches the motor positive pole 400.2. The negative current of the battery or rechargeable mobile power supply 630 flows through the common terminal 540.1 and the normally open contact 540.2 of the intermediate relay KA2-540 and reaches the motor negative pole 400.3. The motor 400 is energized and starts to rotate clockwise.

[0051] Mechanical transmission part: ( Figure 6 、 Figure 7). The motor 400 rotates forward, and the turntable 410 rotates with the motor shaft 400.1. The first end movable hinge pin 302 of the scissor link mechanism 300 passes through the turntable groove 410.1 opened on the turntable 410. The rotation of the turntable 410 drives the first end movable hinge pin 302 to move within the turntable groove 410.1. The first end movable hinge pin 302 changes its position relative to the center of the turntable 410 within the turntable groove 410.1 and follows the rotation of the turntable 410. Since the position of the first end movable hinge pin 302 relative to the center of the turntable 410 changes linearly within the turntable groove 410.1, the rotational motion driven by the turntable 410 is transformed into its own linear sliding motion. Moreover, the linear sliding motion of the first end movable hinge pin within the turntable groove 410.1 also drives the linear sliding motion of the first end movable hinge pin 302 within the hinge pin sliding groove 600.6 of the umbrella handle 600.

[0052] The first end movable hinge pin 302 is inserted into the front end hinge pin hole of the connecting rod 304 of the first scissor unit of the scissor link mechanism 300. Driven by the forward rotation of the turntable 410 driven by the motor 400, the first end movable hinge pin 302 becomes a linear slide within the turntable groove 410.1 and also moves linearly within the hinge pin sliding groove 600.6 of the umbrella handle 600, driving the first scissor unit of the scissor link mechanism 300 composed of the connecting rod 304 and the connecting rod 303 to extend. Each scissor unit of the scissor link mechanism 300 extends respectively ( Figure 1 , Figure 3 ).

[0053] The middle hinge pin 311 moves upward along the groove from the bottom of the second section rod longitudinal groove 120.4 with the scissor unit composed of the connecting rod E309 and the connecting rod F310 driven by the extension of the scissor link mechanism 300.

[0054] The last scissor unit composed of the connecting rod C (320) and the connecting rod D (321) is connected to the pressing block (200). The end movable hinge pin 331 moves upward with the overall extension of the scissor link mechanism 300 and slides within the hinge pin groove of the pressing block 200. The upward movement of the end movable hinge pin 331 with the extension of the scissor link mechanism 300 and its sliding within the pressing block hinge pin groove 200.2 drive the pressing block 200 to move upward along the third section rod groove 130.1 ( Figure 4)(The briquette 200 is fixed on the lower nest 140. The lower nest 140 is sleeved on the umbrella rod, and the upward movement of the briquette 200 drives the lower nest 140 to slide upward on the umbrella rod. The first support rod 720 hinged on the lower nest 140 moves upward with the lower nest 140 and straightens. One end of the first pull rod 710 is hinged on the three-way joint on the first support rod 720. With the upward movement and straightening of the first support rod 720, the first pull rod 710 is jacked upward, and the other end of the first pull rod 710 is hinged on the upper nest 150. With the first pull rod 710 being jacked upward by the first support rod 720, the upper nest 150 hinged to one end of the first pull rod 710 is also driven to move upward by the first pull rod 710. The upper nest 150 is fixed on the third section rod 130, and the third section rod moves upward with the upward movement of the upper nest. The third section rod 130 moves upward under the cooperation of the third section rod limit block 120.2 and the third section rod guide groove 130.2 on the second section rod 120. When the third section rod 130 moves upward so that the third section rod limit block 120.2 on the second section rod 120 touches the bottom edge of the third section rod guide groove 130.2, the third section rod limit block 120.2 on the second section rod 120 hooks the upward-moving third section rod 130 and moves upward with the third section rod 130. The second section rod limit block 110.1 on the first section rod 110 slides upward in cooperation with the second section rod guide groove 120.3. Driven by the linear link movement extension of the scissor link mechanism 300, the sleeved second umbrella rod 120 and the third section rod 130 both rise with the extension of the linear link movement of the scissor link mechanism 300 and the elongation of the extended distance. When the second section rod 120 and the third section rod 130 rise with the rise of the scissor link mechanism 300, the middle hinge pin 311 still slides upward along the second section rod longitudinal groove 120.4 with the extension of the scissor link mechanism 300. When the second section rod limit block 110.1 on the first section rod 110 touches the lower bottom edge of the second section rod guide groove 120.3, it hooks the upward-moving second section rod 120. The first section rod is fixed on the umbrella handle 600, and the rise of the second rod (120) is held by the second section rod limit block (110.1) on the first section rod 110 and cannot rise. When the rise of the third section rod (130) is held by the third section rod limit block (120.2) on the second section rod (120) and cannot rise, the upper nest fixed on the third section rod cannot move upward either. However, the scissor link mechanism 300 still extends upward, so that the middle hinge pin 311 still slides upward along the second section rod longitudinal groove 120.4, and the briquette 200 connected to the scissor link mechanism still rises with the extension of the scissor link mechanism 300. The rise of the briquette 200 continues to push the rise of the lower nest 140. The rise of the lower nest 140 squeezes and extends the umbrella skeleton structure 700 clamped between the lower nest and the upper nest that can no longer move upward. One end of the first connecting bone 730 is hinged on the three-way joint of the first pull rod, and the other end is hinged to the second connecting bone. With the rise and straightening of the first support rod 720, the second connecting bone 740 is straightened.)The link mechanism composed of the first connecting bone, the second connecting bone 740, the third connecting bone 750, and the fourth connecting bone 760, after the second connecting bone is straightened and lifted, also straightens and lifts the fourth connecting bone to open the umbrella surface. At the same time, the middle hinge pin 311 moves upward along the longitudinal groove 120.4 of the second rod to the chute 120.1 of the second rod (such as... Figure 1 , Figure 4 , Figure 5 , Figure 14 ). The second rod 120 is held by the middle hinge pin connected to the scissor link mechanism, and the upper nest 150 is held upward by the umbrella skeleton structure 700 lifted by the scissor link mechanism 300. The upper nest 150 then holds the third rod 130 upward, and the third rod 130 is pulled downward by the second rod 120 and the first rod to keep the umbrella surface open.

[0055] When the umbrella surface is fully opened and the umbrella rod is fully extended, the linear movement of the first-end movable hinge pin 302 in the hinge pin chute 600.6 of the umbrella handle 600 touches the handle 520.4 of the open-umbrella limit switch S2, triggering the operation of the open-umbrella limit switch S2 - 520. The common terminal 520.1 of the open-umbrella limit switch S2 is disconnected from the normally closed contact 520.3 of the open-umbrella limit switch S2, cutting off the power supply of the intermediate relay KA2 - 540. The intermediate relay KA2 - 540 loses power, and the common terminal 540.1 of the intermediate relay KA2 is disconnected from the normally open contact 540.2, and the common terminal 540.4 is disconnected from the normally open contact 540.5, and the motor 400 stops rotating ( Figure 12 , Figure 13 ).

[0056] Electric umbrella closing process: ( Figure 12 , Figure 13 ). The scissor link mechanism is in the deployed state. As described above, the umbrella has been in the open state.

[0057] Electrical control section: When the lower end of the boat-shaped switch SB500 is pressed, the normally open contact 500.2 of the boat-shaped switch SB 500 disconnects from the common terminal 500.1, and the normally closed contact 500.3 of the boat-shaped switch SB500 closes with the common terminal 500.1. The positive current of the power supply provided by the battery or rechargeable mobile power source 630 flows through the boat-shaped switch SB-500, the common terminal 510.1 and the normally closed contact 510.3 of the umbrella retraction limit switch S1-510, and reaches the positive pole 530.7 of the intermediate relay KA1-530. The negative pole 530.8 of the intermediate relay KA1-530 is connected to the negative pole of the battery or rechargeable mobile power source 630, and the coil of the intermediate relay KA1-530 is energized. The normally open contact 530.2 of the intermediate relay KA1-530 closes and conducts with the common terminal 530.1, and the other pair of normally open contacts 530.5 also closes and conducts with the common terminal 530.4. The positive current provided by the battery or rechargeable mobile power source 630 flows through the common terminal 530.1 and the normally open contact 530.2 of the intermediate relay KA1-530 and reaches the negative pole 400.3 of the motor. The negative current of the battery or rechargeable mobile power source 630 flows through the common terminal 530.4 and the normally open contact 530.5 of the intermediate relay KA1-530 and reaches the positive pole 400.2 of the motor, changing the polarity of the motor, and the motor 400 is energized and starts to rotate counterclockwise in reverse.

[0058] Mechanical transmission section: (such as Figure 9 ). When the motor 400 rotates in reverse, the turntable 410 rotates with the motor shaft 400.1. The first movable hinge pin 302 of the scissor link mechanism 300 passes through the turntable groove 410.1 opened on the turntable 410. The rotational movement of the turntable 410 drives the first movable hinge pin 302 to linearly slide in the turntable groove 410.1. The first movable hinge pin 302 changes its position relative to the center of the turntable 410 in the turntable groove 410.1 and follows the rotation of the turntable 410. Since the position of the first movable hinge pin 302 relative to the center of the turntable 410 in the turntable groove 410.1 changes linearly, the rotational movement driven by the turntable 410 is changed into its own linear sliding movement in the turntable groove 410.1. And it also pushes the first movable hinge pin 302 to linearly slide in the hinge pin sliding groove 600.6 of the umbrella handle 600.

[0059] The first movable hinge pin 302 is inserted into the front hinge pin hole of the connecting rod 304 of the first scissor unit of the scissor link mechanism 300. The reverse rotation of the turntable 410 pushes the first movable hinge pin 302 to linearly slide in the hinge pin sliding groove 600.6 of the umbrella handle 600, and also pushes the first scissor unit composed of the connecting rod 304 and the connecting rod 303 to fold. Each scissor unit of the scissor link mechanism 300 folds respectively, and the scissor link mechanism 300 unfolds and folds.

[0060] The intermediate hinge pin 311 moves downward along the longitudinal groove 120.4 of the second rod with the scissor unit composed of the connecting rod E309 and the connecting rod F310 driven by the folding of the scissor connecting rod mechanism 300, and the second rod 120 loses the support of the scissor connecting rod mechanism 300.

[0061] The end scissor unit composed of connecting rod C (320) and connecting rod D (321) is connected to the pressure block (200). The terminal movable hinge pin 331 moves downward with the overall folding of the scissor-fork connecting rod mechanism 300, and slides in the hinge pin groove of the pressure block 200. The downward movement of the terminal movable hinge pin 331 and the sliding in the hinge pin groove 200.2 of the pressure block drive the pressure block 200 to move downward along the third section rod groove 130.1. The pressure block 200 is fixed on the lower nest 140. The lower nest 140 is sleeved on the umbrella pole, and the downward movement of the pressure block 200 drives the lower nest 140 to slide downward on the umbrella pole. The first support rod 720 hinged on the lower nest 140 moves downward with the lower nest 140 and folds. One end of the first pull rod 710 is hinged on the three-prong joint on the first support rod 720. As the first support rod 720 moves downward and folds, the first pull rod 710 is pulled downward, and the other end of the first pull rod 710 is hinged on the upper nest 150. As the first pull rod 710 is pulled downward by the first support rod 720, the upper nest 150 hinged to one end of the first pull rod 710 is also driven downward by the first pull rod 710. The upper nest 150 is fixed on the third section rod 130, and the third section rod moves downward as the upper nest moves downward. The third section rod guide groove 130.2 moves downward in coordination with the third section rod limit block 120.2 on the second section rod 120. When the upper edge of the third section rod guide groove 130.2 contacts the third section rod limit block 120.2 on the second section rod 120, the upper edge of the third section rod guide groove 130.2 hooks the third section rod limit block 120.2 on the second section rod 120, driving the second section rod 120 to descend as the third section rod 130 descends. Or, depending on the different position settings, the pressing block 200 that moves downward with the scissor-fork linkage mechanism 300 can also be set as the power to press down the second section rod 120. The second section rod guide groove 120.3 cooperates with the second section rod limit block 110.1 on the first section rod 110 to move downward. Driven by the linear link motion folding of the scissor-fork linkage mechanism 300, the sleeved second section umbrella rod 120 and the third section umbrella rod 130 are folded along with the linear link motion of the scissor-fork linkage mechanism 300, and the extended distance becomes smaller and moves downward. When the bottom of the second section rod 120 moves down to the umbrella handle socket groove 600.2, it stops moving downward due to support, or according to the different position settings, the second section rod limit block 110.1 on the first section rod 110 supports the upper edge of the second section rod guide groove 120.3 to prevent the second section rod 120 from moving further downward. The second section rod is stopped from moving downward by the umbrella handle socket 600.2 or the second section rod stopper 110.1, the upper edge of the third section rod guide groove 130.2 is supported by the third section rod stopper 120.2 on the second section rod 120 and cannot move downward, and the upper nest 150 fixed to the third section rod 130 also stops moving downward. The scissor-fork linkage mechanism 300 continues to move downward, driving the middle hinge pin 311 connected to the scissor-fork unit to continue to slide downward along the second section rod longitudinal groove.The downward movement of the scissor link mechanism 300 still drives the pressing block 200 connected to the scissor unit to continue moving downward. The downward movement of the pressing block 200 drives the lower nest 140 to move downward accordingly. The downward movement of the lower nest 140 stretches the umbrella frame structure 700 clamped between the lower nest and the upper nest that has stopped moving downward.

[0062] One end of the first support rod 720 moves downward with the downward movement of the lower nest 140, pulling the first pull rod 710 downward. One end of the first connecting bone 730 is hinged to the three-way joint installed on the first pull rod 710, and the other end is hinged to the second connecting bone 740. With the downward movement and folding of the first support rod 720, the second connecting bone 740 is driven to fold. The link mechanism composed of the first connecting bone 730, the second connecting bone 740, the third connecting bone 750, and the fourth connecting bone 760 drives the fourth connecting bone to fold and the umbrella surface to be retracted after the second connecting bone folds. The intermediate hinge pin 311 moves downward along the longitudinal groove 120.4 of the second rod to the bottom of the longitudinal groove 120.4 of the second rod, and the pressing block 200 moves into the avoidance groove 120.5 of the second rod (as Figure 9 , Figure 10 ).

[0063] When the umbrella surface is closed and all the umbrella rods are retracted, the linear movement of the first end movable hinge pin 302 in the hinge pin chute 600.6 of the umbrella handle 600 touches the umbrella closing limit switch S1 handle 510.4, triggering the action of the umbrella closing limit switch S1 - 510. The common terminal 510.1 of the umbrella closing limit switch S1 is disconnected from the normally closed contact 510.3 of the umbrella closing limit switch S1, cutting off the power supply of the intermediate relay KA1 - 530. The intermediate relay KA1 - 530 loses power, and the common terminal one 530.1 of the intermediate relay KA1 is disconnected from the normally open contact 530.2, and the common terminal two 530.4 is disconnected from the normally open contact 530.5, and the motor 400 is powered off and stops rotating. (As Figure 12 , Figure 13 ).

[0064] Even when the umbrella is in the intermediate position between closing and opening, that is, the first end movable hinge pin neither triggers the umbrella opening limit switch S2 nor triggers the umbrella closing limit switch S1, when the upper or lower end of the boat-shaped switch SB500 is pressed, the umbrella can still be opened or closed in the selected direction, and the umbrella opening and closing will not be started simultaneously.

[0065] Manual umbrella opening process: (See Figure 7 , Figure 8 , Figure 11 ). Manual umbrella opening or closing is used when the battery is out of power or the rechargeable mobile power supply 630 is not connected. The scissor link mechanism 300 is in a folded state. The first end movable hinge pin 302 slides in the hinge pin chute 600.6 of the umbrella handle 600.

[0066] Mechanical transmission part: (See Figure 8 ,Figure 11 ). The parachute-opening handle 380 is hinged to the scissor unit formed by the connecting rod R307 and the connecting rod T308. One end of the parachute-opening handle 380 is hinged to the hinge pin hole at the lower end of the connecting rod R307, and the parachute-opening handle pin A382 is inserted therein; one end of the parachute-opening handle pair 381 is hinged to the parachute-opening handle 380, and the parachute-opening handle pin B383 is inserted into the hinge pin hole therein; the other end of the parachute-opening handle pair 381 is hinged to the hinge pin hole at the upper end of the connecting rod R307, and the parachute-opening handle pin C384 is inserted into the hinge pin hole therein. The parachute-opening handle 380, the parachute-opening handle pair 381, and the connecting rod R307 form a planar linkage mechanism. When pressing the parachute-opening handle 380 by hand, the planar linkage mechanism composed of the parachute-opening handle 380, the parachute-opening handle pair 381, and the connecting rod R307 rotates around the parachute-opening handle pin B383, driving the extension movement of the scissor unit formed by the connecting rod R307 and the connecting rod T308, and further driving the extension of the scissor linkage mechanism 300. The extension of the scissor linkage mechanism 300 also drives the movement of the first-end movable hinge pin 302. While the first-end movable hinge pin 302 makes a linear slide in the hinge pin sliding groove 600.6 of the umbrella handle 600, it also drives the movement of the turntable 410 and the motor 400.

[0067] The middle hinge pin 311 moves upward with the scissor unit formed by the connecting rod E309 and the connecting rod F310 under the drive of the extension of the scissor linkage mechanism 300, and moves upward along the groove from the bottom of the second-section rod longitudinal groove 120.4.

[0068] The last scissor unit composed of the connecting rod C (320) and the connecting rod D (321) is connected to the pressing block (200). The end movable hinge pin 331 moves upward with the overall extension of the scissor linkage mechanism 300 and slides in the hinge pin groove of the pressing block 200. The upward movement and the sliding of the end movable hinge pin 331 in the pressing block hinge pin groove 200.2 drive the pressing block 200 to move upward along the third-section rod groove 130.1 (as Figure 4). The briquette 200 is fixed on the lower nest 140. The lower nest 140 is sleeved on the umbrella rod, and the upward movement of the briquette 200 drives the lower nest 140 to slide upward on the umbrella rod. The first support rod 720 hinged on the lower nest 140 moves upward with the lower nest 140 and straightens. One end of the first pull rod 710 is hinged on the three-way joint on the first support rod 720. With the upward movement and straightening of the first support rod 720, the first pull rod 710 is lifted upward, and the other end of the first pull rod 710 is hinged on the upper nest 150. With the first pull rod 710 being lifted upward by the first support rod 720, the upper nest 150 hinged to one end of the first pull rod 710 is also driven to move upward by the first pull rod 710. The upper nest 150 is fixed on the third section rod 130, and the third section rod moves upward with the upward movement of the upper nest. The third section rod 130 moves upward under the cooperation of the third section rod limit block 120.2 and the third section rod guide groove 130.2 on the second section rod 120. When the third section rod limit block 120.2 on the second section rod 120 contacts the bottom edge of the third section rod guide groove 130.2 when the third section rod 130 moves upward, the third section rod limit block 120.2 on the second section rod 120 hooks the upward moving third section rod 130 and moves upward with the third section rod 130. The second section rod limit block 110.1 on the first section rod 110 slides upward in cooperation with the second section rod guide groove 120.3. Driven by the straight-line link movement extension of the scissor link mechanism 300, the sleeved second umbrella rod 120 and the third umbrella rod 130 both rise with the extension of the straight-line link movement of the scissor link mechanism 300 and the elongation of the extended distance. When the second section rod 120 and the third section rod 130 rise with the rise of the scissor link mechanism 300, the middle hinge pin 311 still slides upward along the second section rod longitudinal groove 120.4 with the extension of the scissor link mechanism 300. When the second section rod limit block 110.1 on the first section rod 110 contacts the lower bottom edge of the second section rod guide groove 120.3, it hooks the upward moving second section rod 120. The first section rod is fixed on the umbrella handle 600, and the rise of the second rod 120 is pulled by the second section rod limit block (110.1) on the first section rod 110 and cannot rise. When the rise of the third section rod 130 is pulled by the third section rod limit block (120.2) on the second section rod 120 and cannot rise, the upper nest fixed on the third section rod cannot move upward either. However, the scissor link mechanism 300 still extends upward, so that the middle hinge pin 311 still slides upward along the second section rod longitudinal groove 120.4, and the briquette 200 connected to the scissor link mechanism still rises with the extension of the scissor link mechanism 300. The rise of the briquette 200 further pushes the lower nest 140 to rise. The rise of the lower nest 140 squeezes and extends the umbrella skeleton structure 700 clamped between the lower nest and the upper nest that can no longer move upward.

[0069] When the umbrella-opening handle 380 is pressed in place, the umbrella rod fully extends and the scissor link mechanism is fully extended.

[0070] One end of the first connecting bone 730 is hinged to the three-way joint of the first pull rod, and the other end is hinged to the second connecting bone. As the first support rod 720 rises and straightens, the second connecting bone 740 is pushed straight. The link mechanism composed of the first connecting bone, the second connecting bone 740, the third connecting bone 750, and the fourth connecting bone 760 pushes the fourth connecting bone straight and upward to open the umbrella surface after the second connecting bone is pushed straight and rises. At the same time, the middle hinge pin 311 moves upward along the longitudinal groove 120.4 of the second rod to the chute 120.1 of the second rod (such as Figure 1 , Figure 4 , Figure 5 , Figure 14 ). The second rod 120 is held by the middle hinge pin connected to the scissor link mechanism, and the upper nest 150 is pushed upward against the umbrella frame structure 700 that rises with the scissor link mechanism 300. The upper nest 150 then pushes and pulls the third rod 130 upward. The third rod 130 is pulled downward by the second rod 120 and the first rod to maintain the continuous support of the umbrella rod. Press the umbrella-opening handle 380 by hand to keep the scissor link mechanism 300 extended. Such as Figure 3 .

[0071] Manual umbrella-closing process: (such as Figure 7 , Figure 8 ). Manual umbrella-opening or -closing is used when the battery is out of power or the rechargeable mobile power source 630 is not connected. The scissor link mechanism 300 is in the extended state. The first-end movable hinge pin 302 slides in the hinge pin chute 600.6 of the umbrella handle 600.

[0072] Mechanical transmission part: The umbrella-closing handle 390 is hinged to the scissor unit composed of link A 305 and link B 306. One end of the umbrella-closing handle 390 is hinged to the lower hinge pin hole of link A 305, and the umbrella-closing handle pin A 392 is inserted therein; one end of the umbrella-closing handle pair 391 is hinged to the umbrella-closing handle 390, and the umbrella-closing handle pin B 393 is inserted into the hinge pin hole therein; the other end of the umbrella-closing handle pair 391 is hinged to the upper hinge pin hole of link A 305, and the umbrella-closing handle pin C 394 is inserted into the hinge pin hole therein. The umbrella-closing handle 390, the umbrella-closing handle pair 391, and link A 305 form a planar link motion mechanism. Press the umbrella-closing handle 390 by hand, and the planar link mechanism composed of the umbrella-closing handle 390, the umbrella-closing handle pair 391, and link A 305 rotates around the umbrella-closing handle pin B 393, driving the folding motion of the scissor unit composed of link A 305 and link B 306, and further driving the folding of the scissor link mechanism 300. The folding of the scissor link mechanism 300 also drives the motion of the first-end movable hinge pin 302. The first-end movable hinge pin 302 makes a linear slide in the hinge pin sliding groove 600.6 of the umbrella handle 600. At the same time, it will also drive the motion of the turntable 410 and the motor 400 (such as Figure 6 , Figure 7 ).

[0073] The middle hinge pin 311 moves downward along the longitudinal groove 120.4 of the second rod following the folding of the scissor unit formed by the connecting rod E 309 and the connecting rod F 310 under the drive of the folding of the scissor connecting rod mechanism 300, and the second rod 120 loses the support of the scissor connecting rod mechanism 300.

[0074] The final scissor unit formed by the connecting rod C (320) and the connecting rod D (321) is connected to the pressing block (200). The end movable hinge pin 331 moves downward following the overall folding of the scissor connecting rod mechanism 300 and slides within the hinge pin groove of the pressing block 200. The downward movement and the sliding of the end movable hinge pin 331 within the hinge pin groove 200.2 of the pressing block drive the pressing block 200 to move downward along the third rod groove 130.1 ( Figure 4). The pressing block 200 is fixed on the lower nest 140. The lower nest 140 is sleeved on the umbrella pole, and the downward movement of the pressing block 200 drives the lower nest 140 to slide and move downward on the umbrella pole. The first support rod 720 hinged on the lower nest 140 moves downward with the lower nest 140 and folds. One end of the first pull rod 710 is hinged on the three-pronged joint on the first support rod 720. As the first support rod 720 moves downward and folds, the first pull rod 710 is pulled downward, and the other end of the first pull rod 710 is hinged on the upper nest 150. As the first pull rod 710 is pulled downward by the first support rod 720, the upper nest 150 hinged to one end of the first pull rod 710 is also driven downward by the first pull rod 710. The upper nest 150 is fixed on the third section rod 130, and the third section rod moves downward as the upper nest moves downward. The third section rod guide groove 130.2 moves downward in coordination with the third section rod stop block 120.2 on the second section rod 120. When the upper edge of the third section rod guide groove 130.2 contacts the third section rod stop block 120.2 on the second section rod 120, the upper edge of the third section rod guide groove 130.2 hooks the third section rod stop block 120.2 on the second section rod 120, driving the second section rod 120 to descend along with the descent of the third section rod 130 (or depending on the different position settings, the pressing block 200 that moves downward along with the scissor-fork linkage mechanism 300 moves downward to drive the second section rod 120 to move downward). The second section rod guide groove 120.3 moves downward in coordination with the second section rod stop block 110.1 on the first section rod 110. Driven by the folding of the linear connecting rod movement of the scissor-fork linkage mechanism, the sleeved second section umbrella rod 120 and the third section umbrella rod 130 are both folded along with the linear motion of the connecting rod of the scissor-fork linkage mechanism, and the extended distance becomes smaller and moves downward. When the bottom of the second section rod 120 moves down to the handle socket 600.2 and is supported, it stops moving down (or, depending on the different positions, the second section rod stopper 110.1 on the first section rod 110 presses against the upper edge of the second section rod guide groove 120.3 to prevent the second section rod 120 from moving down further). The second section rod stops moving down due to the umbrella handle socket 600.2 or the second section rod stopper 110.1, and the upper edge of the third section rod guide groove 130.2 is pressed against by the third section rod stopper 120.2 on the second section rod 120 and cannot move down, and the upper nest 150 fixed on the third section rod 130 also stops moving down. The scissor-fork linkage mechanism 300 continues to move down, driving the middle hinge pin 311 connected to the scissor-fork unit to continue to slide downward along the second section rod longitudinal groove 120.4. The downward movement of the scissor-type linkage mechanism 300 still drives the pressing block 200 connected to the scissor-type unit to continue to move downward. The downward movement of the pressing block 200 drives the lower nest 140 to move downward accordingly. The downward movement of the lower nest 140 stretches the umbrella frame structure 700 sandwiched between the lower nest and the upper nest that has stopped moving downward.

[0075] After the umbrella handle is pressed into place, the umbrella poles are completely retracted, and the scissor-fork connecting rod mechanism is completely folded. The lower end parts of the third section rod 130 and the second section rod 120 are nested in the umbrella handle nest 600.2 of the umbrella handle 600.

[0076] One end of the first support rod 720 moves down as the lower nest 140 moves down, pulling the first pull rod 710 down. One end of the first connecting bone 730 is hinged to the three-way joint of the first pull rod 710, and the other end is hinged to the second connecting bone 740. As the first support rod 720 moves down and folds, it drives the second connecting bone 740 to fold. The link mechanism composed of the first connecting bone 730, the second connecting bone 740, the third connecting bone 750, and the fourth connecting bone 760 drives the fourth connecting bone to fold and retracts the umbrella surface after the second connecting bone folds. The middle hinge pin 311 moves down along the longitudinal groove 120.4 of the second rod to the bottom of the longitudinal groove 120.4 of the second rod, and the pressing block 200 moves into the avoidance groove 120.5 of the second rod (such as Figure 9 , Figure 10 ).

[0077] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope recorded in this specification.

[0078] The above-described embodiments only represent several implementation manners of the present invention. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the invention patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention patent should be subject to the appended claims.
