[0025] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the relevant drawings. The preferred embodiments of the present invention are given in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thoroughly understood.

[0026] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be an element in the middle. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be an element in the middle. The terms "inside", "outside", "left", "right", "upper", "lower", and similar expressions used herein are for illustrative purposes only and are not intended to be the only implementation method. For ease of description, this article intends to take the direction toward the upper nest as the upper direction, the direction toward the handle as the lower direction, the center line of the middle rod as the longitudinal direction, and the direction perpendicular to the center line as the transverse direction.

[0027] A one-handed umbrella, such as Figure 1 As shown, it includes a middle rod (220), an upper nest (300), a middle nest (290), a lower nest (280), an impulse mechanism (25) and a main spring (240). The upper nest (300) is fixedly connected to the middle rod (220). The middle nest (290), the lower nest (280), the impulse mechanism (25) and the main spring (240) can slide along the middle rod (220). The two ends of the main spring (240) are respectively connected to the impulse mechanism (25) and the lower nest (280).

[0028] like Figure 2 As shown, the middle rod (220) is provided with a middle rod latch hole (220.2). Figure 5 As shown, the impulse mechanism (25) includes a latch (260), one end of which can extend into or out of the middle rod latch hole (220.2). Both ends of the main spring (240) abut against the impulse mechanism (25) and the lower nest (280).

[0029] When one end of the bayonet (260) extends into the bayonet hole (220.2) of the middle rod, the impulse mechanism (25) is locked to the middle rod (220), and when one end of the bayonet (260) exits the bayonet hole (220.2) of the middle rod, the impulse mechanism (25) can slide along the middle rod (220). Specifically, the impulse mechanism (25) moves toward the middle nest (290) under the action of the main spring (240).

[0030] like Figure 2As shown, it also includes a scissor-type fulcrum movable lever structure (20), a relay rod (231) and an umbrella handle (100). The scissor-type fulcrum movable lever structure (20) is arranged at the umbrella handle (100), the relay rod (231) is slidably connected to the middle rod (220), one end of the relay rod (231) is connected to the scissor-type fulcrum movable lever structure (20), and the other end is connected to the middle nest (290), and when the relay rod (231) moves relative to the middle rod (220), the latch pin (260) can be withdrawn from the middle rod latch pin hole (220.2). The scissor-type fulcrum movable lever structure (20) comprises a scissor-type lever mechanism (15) and a scissor-type connecting rod mechanism (17); the scissor-type lever mechanism (15) is connected to the relay rod (231) via the scissor-type connecting rod mechanism (17); pressing the scissor-type lever mechanism (15) can drive the relay rod (231) to move along the axis direction of the middle rod (220).

[0031] like Fig. 9 As shown, the scissor-type lever mechanism (15) comprises a left shear rod (151), a right shear rod (152) and a shear rod fulcrum hinge pin (153); the left shear rod (151) and the right shear rod (152) are hingedly connected via the shear rod fulcrum hinge pin (153); the shear rod fulcrum hinge pin (153) serves as a fulcrum and can move along the length direction of the umbrella handle (100).

[0032] like Fig.10 As shown, the scissor-type connecting rod mechanism (17) comprises a first scissor-fork unit (170), a second scissor-fork unit (176), and a final scissor-fork unit (180) connected in series, the first scissor-fork unit (170) and the final scissor-fork unit (180) being able to approach or move away from each other, the first scissor-fork unit (170) being connected to the umbrella handle (100), and the final scissor-fork unit (180) being connected to the relay pole (231).

[0033] like Figure 3As shown, it also includes a conversion block (190) for connecting the end scissor fork unit (180) and the relay rod (231), the conversion block (190) is provided with a conversion block movable hinge pin groove (190.1), the end scissor fork unit (180) is provided with a fixed hinge pin 3 (193) and a movable hinge pin 4 (194) that can be moved closer or farther away, the fixed hinge pin 3 (193) is connected to the conversion block (190), and the movable hinge pin 4 (194) is slidably connected to the conversion block movable hinge pin groove (190.1). The left shear rod (151) is provided with a left shear rod fixed pin track groove (151.4) and a left shear rod movable pin track groove (151.3), and the right shear rod (152) is provided with a right shear rod fixed pin track groove (152.4) and a right shear rod movable pin track groove (152.3); when the umbrella is closed, the fixed hinge pin 3 (193) slides along the left shear rod fixed pin track groove (151.4) and also slides into the right shear rod fixed pin track groove (152.4), and the movable hinge pin 4 (194) slides along the right shear rod movable pin track groove (152.3) and also slides into the left shear rod movable pin track groove (151.3).

[0034] like Figure 3 As shown, the first scissor-fork unit (170) is provided with a fixed hinge pin 1 (191) and a movable hinge pin 2 (192) that can be moved closer or farther away, the fixed hinge pin 1 (191) is connected to the umbrella handle (100), the umbrella handle (100) is provided with an umbrella handle (100) movable pin groove (100.6), and the movable hinge pin 2 (192) is slidably connected to the umbrella handle (100) movable pin groove (100.6).

[0035] The working principle is as follows: according to the law of energy conservation, when closing the umbrella, energy is input by pressing the left shear rod (151) and the right shear rod (152) of the scissor-type lever mechanism (15). In addition to natural consumption, part of the input energy is used for closing the umbrella, and the other part is stored in the compressed main spring (240). When opening the umbrella, the energy stored in the main spring (240) is used in the opening process.

[0036] like Figure 5 As shown, when the umbrella is in a fully unfolded state, the latch (260) is latched into the latch hole (220.2) of the middle rod, so that the impulse mechanism (25) is fixed relative to the middle rod (220).

[0037] When closing the parachute, firstly, the left shear rod (151) and the right shear rod (152) of the scissor-type pivot movable lever structure (20) are pressed to input energy, so that the relay rod (231) moves upward along the middle rod (220). Since the upper end of the relay rod (231) is connected to the middle nest (290), the middle nest (290) moves upward along the middle rod (220) along with the relay rod (231), and since the impulse mechanism (25) is fixed relative to the middle rod (220), the middle nest (290) moves upward away from the impulse mechanism (25). Since the middle nest (290) and the lower nest (280) are connected by other connecting rod mechanisms of the umbrella, the middle nest (290) and the lower nest (280) move upward along the middle rod (220) synchronously. Since both ends of the main spring (240) abut against the impulse mechanism (25) and the lower nest (280), during this process, the lower nest (280) moves upward to compress the main spring (240) to store energy.

[0038] Furthermore, as the relay pole (231) moves further upward, the relay pole circular wedge (231.2) pushes the latch pin (260) out of the middle rod latch pin hole (220.2), and the impulse mechanism (25) becomes movable relative to the middle rod (220). Under the action of the main spring (240), the impulse mechanism (25) strikes the middle nest (290) upward to assist the umbrella closing process. Although the main spring (240) assists the umbrella closing process, the main spring (240) is still in a compressed state, and as the left shear rod (151) and the right shear rod (152) of the scissor-type pivot movable lever structure (20) are further pressed, the main spring (240) further stores energy. Fig.10 As shown, until the hook (120) hooks the fixed hinge pin 1 (191), the umbrella is locked so that it cannot be opened. At this time, the umbrella closing action is completed.

[0039] When the umbrella is fully closed, the main spring (240) is compressed and stores energy.

[0040] When opening the umbrella, the button (110) is pressed to disengage the hook (120) from the fixed hinge pin 1 (191), and the main spring (240) releases energy to open the umbrella.

[0041] The specific structure is introduced in detail below.

The button spring (111) is used to realize the reset of the button (110).

[0045] The scissor-type lever mechanism with movable fulcrum (20) comprises the scissor-type connecting rod mechanism (17) and the scissor-type lever mechanism (15). The combination of the scissor-type connecting rod mechanism (17) and the scissor-type lever mechanism (15) realizes a lever mechanism with movable fulcrum, providing initial power for closing the umbrella.

The serial scissor-fork units of the scissor-fork linkage mechanism (17) include the first scissor-fork unit (170), the second scissor-fork unit (176) to the last scissor-fork unit (180). The first scissor-fork unit (170) includes the shear rod 1 (171) and the shear rod 2 (172). The shear rod 1 (171) is provided with three pin holes, namely, the front pin hole (171.0) of the shear rod 1, the middle pin hole (171.1) of the shear rod 1, and the tail pin hole (171.2) of the shear rod 1. The shear rod 2 (172) is provided with the same pin holes. For the convenience of description herein, the scissor-fork units constituting the scissor-fork linkage mechanism (17) all include two shear rods. The shear rod 1 and the shear rod 2 are provided with the same pin holes as the shear rod 1 (171) so as to realize equidistant and symmetrical scissor-fork motion. The second scissor fork unit (176) and the final scissor fork unit (180) connected in series with the first scissor fork unit (170) also include a shear rod 1 and a shear rod 2. In the first scissor fork unit (170), the pin hole (171.1) in the shear rod 1 and the pin hole (172.1) in the shear rod 2 are hinged through an intermediate hinge pin 5 (195) to form a scissor-fork structure, the front pin hole (171.0) of the shear rod 1 and the fixed pin hole (100.5) of the umbrella handle are hinged through the fixed hinge pin 1 (191), and the front pin hole (172.0) of the shear rod 2 is slidably connected to the movable pin groove (100.6) of the umbrella handle through the movable hinge pin 2 (192). The second scissor-fork unit (176) is connected in series after the first scissor-fork unit (170), the tail pin hole (171.2) of the shear rod 1 of the first scissor-fork unit and the front pin hole (178.0) of the shear rod 2 of the second scissor-fork unit are hinged through the left shear rod resistance arm pin (154), the tail pin hole (172.2) of the shear rod 2 of the first scissor-fork unit and the front pin hole (177.0) of the shear rod 1 of the second scissor-fork unit are hinged through the right shear rod resistance arm pin (155), and the left shear rod resistance arm pin (154) is also hinged with the left shear rod bottom pin hole (151.2), and the right shear rod resistance arm pin (155) is also hinged with the right shear rod bottom pin hole (152.2). The subsequent scissor-fork units are connected in series in sequence. In the terminal scissor fork unit (180), the pin hole (181.1) in the shear rod 1 and the pin hole (182.1) in the shear rod 2 are hinged through a hinge pin, following the connection method of the previous scissor fork units, the tail pin hole (181.2) of the shear rod 1 is hinged with the movable hinge pin 4 (194), the movable hinge pin 4 (194) is slidably connected with the movable hinge pin groove (190.1) of the conversion block, the tail pin hole (182.2) of the shear rod 2 is hinged with the fixed hinge pin hole (190.0) of the conversion block through the fixed hinge pin 3 (193), and the terminal scissor fork unit (180) moves in the movable groove (190.3) of the shear rod of the conversion block. The scissor-type connecting rod mechanism (17) moves in the space opened by the umbrella handle longitudinal groove (100.4) and the umbrella handle transverse groove (100.3).

[0047] The scissor-type connecting rod mechanism (17) performs the umbrella closing movement as follows: a person presses the components in the scissor-type lever mechanism (15) - the left shear rod (151) and the right shear rod (152) - in a horizontal direction, and the scissor-type lever mechanism (15) transmits the power of the person's hand to the left shear rod resistance arm pin (154) and the right shear rod resistance arm pin (155). The left shear rod bottom pin hole (151.2), the first scissor-type unit shear rod 1 tail pin hole (171.2), and the second scissor-type unit shear rod 2 front pin hole (178.0) are all hinged through the left shear rod resistance arm pin (154); the right shear rod bottom pin hole (152.2), the first scissor-type unit shear rod 2 tail pin hole (172.2), and the second shear rod unit shear rod 1 front pin hole (177.0) are all hinged through the right shear rod resistance arm pin (155). The force exerted on the left shear rod resistance arm pin (154) and the right shear rod resistance arm pin (155) is transmitted to the connection between the first scissor unit (170) and the second scissor unit (176) of the scissor-type linkage mechanism (17), and the shear rods of the scissor-type linkage mechanism (17) are subjected to lateral pressure on both sides, and the scissor-type linkage mechanism (17) is extended. The conversion block (190) is at the end of the scissor-type linkage mechanism (17) and converts the extension movement of the scissor-type linkage mechanism (17) into the linear displacement movement of the platform.

[0048] The scissor-type connecting rod mechanism (17) performs the umbrella opening movement as follows: the conversion block (190) is subjected to the downward thrust of the long-distance thrust mechanism (23), and the conversion block (190) moves downward in a straight line, so that the scissor-type connecting rod mechanism (17) is pressed downward and folded. The left shear rod resistance arm pin (154) and the right shear rod resistance arm pin (155) are subjected to the folding of the scissor-type connecting rod mechanism (17), driving the scissor-type lever mechanism (15) composed of the left shear rod (151) and the right shear rod (152) to fold, and the left shear rod power arm (151.1) and the right shear rod power arm (152.1) are opened to facilitate the next pressing of the umbrella. The scissor-type connecting rod mechanism (17) is a linear motion mechanism, which realizes linear displacement by driving the extension and contraction of each scissor-type unit. In a specific embodiment, the linear displacement realized by the linear motion mechanism is not limited to the scissor-type connecting rod mechanism (17) described in this article, and the number of scissor rods and the connection method of each scissor-type unit are not limited to those set in this article. Figure 6 ).

[0050] The scissor-type lever mechanism (15) performs the umbrella closing movement: a person manually presses the left shear rod power arm (151.1) and the right shear rod power arm (152.1) to make them tend to move closer, the left shear rod resistance arm (151.5) and the right shear rod resistance arm (152.5) ​​rotate around the shear rod fulcrum hinge pin (153), and the left shear rod resistance arm (151.5) and the right shear rod resistance arm (152.5) ​​tend to move closer; the right shear rod resistance arm (152.5) ​​pries the right shear rod resistance arm pin (155) hinged thereto, and the right shear rod resistance arm pin (155) pries The end of the tail pin hole (172.2) of the shear rod 2 of the first scissor-fork unit is moved; the left shear rod resistance arm (151.5) pries the left shear rod resistance arm pin (154) hinged thereto, and the left shear rod resistance arm pin (154) pries the end of the tail pin hole (171.2) of the shear rod 1 of the first scissor-fork unit, and the end of the tail pin hole (171.2) of the shear rod 1 of the first scissor-fork unit and the end of the tail pin hole (172.2) of the shear rod 2 of the first scissor-fork unit move closer as the left shear rod resistance arm (151.5) and the right shear rod resistance arm (152.5) ​​move closer, so that the scissor-fork type connecting rod mechanism (17) is extended. Due to the extension of the scissor-type linkage mechanism (17), the fulcrum of the scissor-type lever mechanism (15), i.e., the shear rod fulcrum hinge pin (153), is hinged to the left shear rod middle pin hole (151.0) and the right shear rod middle pin hole (152.0), and the left shear rod bottom pin hole (151.2) and the right shear rod bottom pin hole (152.2) are respectively hinged to the shear rods of the first scissor unit (170) of the scissor-type linkage mechanism (17), so the shear rod fulcrum hinge pin (153) moves with the extension of the scissor-type linkage mechanism (17).

[0051] The scissor-type lever mechanism (15) performs the umbrella opening movement; the scissor-type connecting rod mechanism (17) is subjected to the downward thrust of the long-distance thrust mechanism (23), and the scissor-type connecting rod mechanism (17) is folded. The left shear rod bottom pin hole (151.2) and the first scissor unit shear rod 1 tail pin hole (171.2) are hinged through the left shear rod resistance arm pin (154); the right shear rod bottom pin hole (152.2) and the first scissor unit shear rod 2 tail pin hole (172.2) are hinged through the right shear rod resistance arm pin (155). As the scissor-type lever mechanism (15) is folded, the left shear rod resistance arm pin (154) and the right shear rod resistance arm pin (155) tend to open, driving the left shear rod resistance arm (151.5) and the right shear rod resistance arm (152.5) ​​to open, further driving the left shear rod power arm (151.1) and the right shear rod power arm (152.1) to open. As when the umbrella is closed, the shear rod fulcrum hinge pin (153) moves as the scissor-type connecting rod mechanism (17) is folded.

[0052] Long-distance thrust mechanism (23): includes the relay rod (231), the adapter block (232), the latch (233), the middle nest (290), the middle rod (220) and other components. Figure 4 , Figure 5 , Figure 7 , Figure 8 , Fig.11 , Fig.12 , Fig.14 The long-distance thrust mechanism (23) moves inside the middle rod (220) and the umbrella handle (100). One end of the relay rod (231) is connected to the conversion block (190), and the other end is connected to the adapter block (232); the latch (233) passes through the adapter block latch slot (232.1) and also passes through the middle rod latch slot (220.1), and the parts exposed outside the middle rod (220) at both ends are fixed in the middle nest latch slot (290.1), and the latch (233) slides along the middle rod latch slot (220.1).

[0053] The long-distance thrust mechanism (23) performs the umbrella closing movement: after receiving the driving force transmitted by the scissor-type fulcrum movable lever mechanism (20), the relay rod (231) moves upward in the middle rod (220), and transmits the driving force of the scissor-type fulcrum movable lever mechanism (220) to the adapter block (232), and the adapter block (232) transmits the driving force to the latch (233), and the latch (233) slides in the middle rod latch slot (220.1) and then transmits the driving force to the middle nest (290), thereby starting the umbrella frame assembly mechanism (40) to perform the umbrella closing movement. When the relay pole (231) moves upward in the middle rod (220), the outer contour motion curve of the relay pole circular wedge (231.2) pushes the latch pin (260) out of the middle rod latch pin hole (220.2), so that the large punch (250) stuck on the middle rod (220) is no longer stuck and can slide on the middle rod (220). After the umbrella frame assembly mechanism (40) completes the umbrella opening movement, the component in the long-distance thrust mechanism (23) - the latch pin (233) also slides along the middle rod latch pin slot (220.1) to the bottom edge (220.3) of the middle rod latch pin slot and is limited, and the umbrella is fully opened.

[0054] The long-distance thrust mechanism (23) performs the umbrella opening movement: during the umbrella opening process, the long-distance thrust mechanism (23) receives the downward pressure transmitted by the umbrella frame assembly mechanism (40) during the umbrella opening movement, and the middle nest (290) in the umbrella frame assembly mechanism (40) during the umbrella closing movement moves downward, pushing the latch (233), a component in the long-distance thrust mechanism (23), to move downward, and the long-distance thrust mechanism (23) performs the umbrella opening movement. The latch (233) transmits the downward thrust of the middle nest (290) to the transfer block (232), and the transfer block (232) transmits it to the relay rod (231), starting the scissor-type fulcrum movable lever mechanism (20) to perform the umbrella closing movement. The long-distance thrust mechanism (23) connects the upper and lower parts to transmit force during the umbrella opening and closing process, extending the distance, direction and range of force transmission.

[0055] The umbrella frame assembly mechanism (40) includes the long bone (310), the short bone (320), the iron groove (330), the upper nest (300), the middle nest (290), the lower nest (280), the main spring (240), the middle rod (220) and other components. Figure 1 , Figure 2 , Figure 4 , Figure 5 , Figure 7 , Figure 8 , Fig.11 , Fig.12 , Fig.14. The umbrella rib assembly mechanism (40) includes an iron groove lever mechanism (31) and a six-link mechanism (36), and the iron groove lever mechanism (31) includes the short bone (320), the iron groove (330), the iron groove fulcrum hinge pin (331), and the long bone (310). In the umbrella frame assembly mechanism (40), a plurality of long bones (310) are distributed along the circumference of the upper nest (300), a plurality of short bones (320) are distributed along the circumference of the middle nest (290), and a plurality of iron grooves (330) are distributed along the circumference of the lower nest (280). For the convenience of description, the umbrella frame assembly mechanism (40) consisting of a pair of long bones (310), a pair of short bones (320), and a pair of iron grooves (330) is simplified as an example for description ( Figure 1 In the umbrella frame assembly mechanism (40), the upper nest (300) is fixed to the top of the middle rod (220), the middle nest (290) is sleeved on the middle rod (220), so the lower nest (280) is sleeved on the middle rod (220); the long bone (310) supports the umbrella surface, and the front pin hole (310.1) of the long bone at one end is hingedly fixed to the upper nest wire (301) on the upper nest wire. The iron groove (330) supports the opening and closing of the long bone (310), the front pin hole (330.2) of the iron groove is hingedly fixed to the lower nest iron wire (281) on the lower nest iron wire groove (280.3), the tail pin hole (330.4) of the iron groove is hingedly fixed to the middle joint (310.2) of the long bone; the short bone pin hole 1 (320.0) is hingedly fixed to the middle nest iron wire (291) In the middle nest iron wire groove (290.3), the short bone pin hole 2 (320.1) at the other end is hinged to the iron groove middle pin hole (330.3) through the iron groove fulcrum hinge pin (331); one end of the main spring (240) is seated on the lower nest ear hole (280.1), the large punch (250) presses the other end of the main spring (240), the middle nest (290) is above the large punch (240), and the short bone (320) pulls the middle nest (290) and the lower nest (280) at both ends respectively; the short bone (320), the middle nest (290), the iron groove (330), and the lower nest (280) form a six-link mechanism (36) to slide on the middle rod (220) to start the movement of compressing the main spring (240) or releasing the elastic force of the main spring (240).

[0056] When the umbrella is closed, the power provided by the scissor-type fulcrum movable lever mechanism (20) is transmitted to the long-distance thrust mechanism (230), and the component latch (233) in the long-distance thrust mechanism (230) pushes the middle nest (290) upward, and the umbrella frame assembly mechanism (40) performs the umbrella closing movement. The component of the umbrella frame assembly mechanism (40) - the middle nest (290) is subjected to the upward thrust applied by the latch (233), driving the short bone (320) to move upward; the upward movement of the short bone (320) drives the upward movement of the iron groove fulcrum hinge pin (331) hinged thereto, and applies an upward pulling force to the iron groove (330) through the iron groove fulcrum hinge pin (331); and the long bone (310) hinged to the iron groove tail pin hole (330.4) applies downward pressure to the iron groove rear section (330.1) during the umbrella closing process. In this state, the short bone (320), the iron groove (330), the iron groove fulcrum hinge pin (331), and the long bone (310) launch the umbrella closing movement of the iron groove lever mechanism (31). The rear section (330.1) of the iron trough is a power arm, the front section (330.0) of the iron trough is a resistance arm, the iron trough fulcrum hinge pin (331) is the fulcrum of the iron trough lever mechanism (31), the short bone pin hole 2 (320.1) and the pin hole (330.3) in the iron trough are hinged through the iron trough fulcrum hinge pin (331), and the fulcrum position of the iron trough fulcrum hinge pin (331) in the movement of the iron trough lever mechanism (31) is determined. The long bone (310) applies downward pressure to the power arm of the iron groove lever mechanism (31) - the rear section (330.1) of the iron groove, and the iron groove fulcrum hinge pin (331) serving as the fulcrum of the iron groove lever mechanism (31) is exerted with an upward pulling force by the short bone (320). The power arm of the iron groove lever mechanism (31) - the rear section (330.1) of the iron groove rotates downward along the lever fulcrum - the iron groove fulcrum hinge pin (331), and the resistance arm of the iron groove lever mechanism (31) - the front section (330.0) of the iron groove is tilted upward, and the lower nest iron wire (281) is hinged to the front pin hole (330.2) of the iron groove and fixed to the lower nest iron wire groove (280.3). The upward tilt of the front section (330.0) of the iron groove pries the lower nest (280) upward along the middle rod (220). The upward movement of the lower nest (280) unfolds the six-bar linkage (36) to compress the main spring (240).During the umbrella closing movement of the iron groove lever mechanism (31), the resistance arm, i.e., the front section (330.0) of the iron groove, is one of the connecting rods of the six-link mechanism (36). The upward tilt of the front section (330.0) of the iron groove pries the lower nest (280) upward. The displacement length of the lower nest (280) moving upward on the middle rod (220) is converted from the rotation angle of the front section (330.0) of the iron groove, and the linear displacement of the short bone (320) driven upward by the middle nest (280) must also be added. The sum of these two displacement lengths is greater than the displacement length of the middle nest (290) on the middle rod (220) during the umbrella closing movement when the umbrella frame assembly mechanism (40) is unfolded. That is, during the movement of the umbrella frame assembly mechanism (40) to unfold and close the umbrella, the speed at which the lower nest (280) moves upward is greater than the speed of the middle nest (290), and the distance between the lower nest (280) and the middle nest (290) decreases as the umbrella frame assembly mechanism (40) further closes the umbrella, and the distance changes from B to A. The two short bones (320) as two connecting rods constituting the six-bar linkage (36) move upward along with the middle nest (290), the two front sections of the iron groove (330.0) as two connecting rods constituting the six-bar linkage (36) are tilted upward, the lower nest (280) as a connecting rod constituting the six-bar linkage (36) moves upward along the middle rod (220) in a straight line, the middle nest (290) as a connecting rod constituting the six-bar linkage (36) also moves upward along the middle rod (220) in a straight line, according to the hinge relationship between the connecting rods, the speed of the lower nest (280) moving upward is greater than that of the middle nest (290), the distance between the lower nest (280) and the middle nest (290) on the middle rod (220) becomes smaller and smaller, and the main spring (240) between the middle rod (220) and the lower nest (280) is compressed. When the umbrella frame assembly mechanism (40) is performing the umbrella closing movement, the iron groove lever mechanism (36) performs the lever movement to pry the lower nest (280) upward on the middle rod (220), and the rotation and linear displacement movements performed by each link of the six-link mechanism (36) compress the main spring (240). As the scissor-type fulcrum movable lever mechanism (20) continues to provide thrust, the long-distance thrust mechanism (23) further transmits this thrust, and the umbrella frame assembly mechanism (40) further unfolds the umbrella closing movement, the middle nest (290) enters the ear hole (300.1) of the upper nest, and the component of the button mechanism (11) - the hook (120) hooks the fixed hinge pin 1 (191), so that the scissor-type link mechanism (17) remains extended unchanged, and the main spring (240) pushed up by the long-distance thrust mechanism (23) remains compressed unchanged, and the umbrella frame assembly mechanism (40) is completed.

[0057] When opening the umbrella, the button (110) of the button mechanism (11) is pressed, the hook (120) is unhooked from the fixed hinge pin 1 (191), and the scissor-type connecting rod mechanism (17) no longer maintains the extended state, but becomes free and deformed, so that the main spring (240), a component of the umbrella frame assembly mechanism (40), no longer maintains the compressed state. The middle nest (290) is pulled between the iron groove fulcrum hinge pin (331) by the short bone (320), and the middle nest (290) can no longer move upward. The middle nest (290) abuts against the large punch (250), and the large punch (250) abuts against the main spring (240). The end of the middle nest (290) becomes the fixed end of the main spring (240) to release the elastic force; the lower nest (280) becomes free in the scissor-type connecting rod mechanism (17), and the main spring (240) is seated in the lower nest ear hole (280.1). When the button (110) is pressed, the elastic force of the main spring (240) is applied to the lower nest (280). The middle nest (290) becomes the fixed end for releasing the elastic force of the main spring (240). The elastic force of the main spring (240) is applied to the lower nest (280). The main spring (240) drives the lower nest (280) to move downward, and the downward elastic force of the main spring (240) is released. The lower nest (280) is moved downward, and the umbrella frame assembly mechanism (40) performs the umbrella opening movement. The component of the umbrella frame assembly mechanism (40) - the lower nest (280) bears the downward force applied by the main spring (240) and moves downward, driving the front section (330.0) of the iron groove to move downward. The brown middle nest (290) bears the reverse thrust of the main spring, and the main spring (240) presses against one end of the middle nest (290) and does not immediately move downward with the downward movement of the lower nest (280), while the short bone (320) hinged with the middle nest iron wire (291) and fixed on the middle nest iron wire groove (290.3) is pulled by the middle nest (290) and does not move downward, and the short bone (320) also pulls the iron groove fulcrum hinge pin (331) hinged with the short bone pin 2 (320.1); the front section (330.0) of the iron groove moves with the lower nest (280). The nest (280) moves downward while the iron groove fulcrum hinge pin (331) does not move downward immediately, so that the front section (330.0) of the iron groove rotates and moves downward around the iron groove fulcrum hinge pin (331); and the long bone (310) hinged to the iron groove tail pin hole (330.4) still applies downward pressure to the rear section (330.1) of the iron groove during the umbrella opening process. In this state, the short bone (320), the iron groove (330), the iron groove fulcrum hinge pin (331) and the long bone (310) start the umbrella opening movement of the iron groove lever mechanism (31).The rear section (330.1) of the iron groove is a resistance arm, the front section (330.0) of the iron groove is a power arm, the iron groove fulcrum hinge pin (331) is the fulcrum of the iron groove lever mechanism (31), the short bone pin hole 2 (320.1) and the pin hole (330.3) in the iron groove are hinged through the iron groove fulcrum hinge pin (331), and the fulcrum position of the iron groove fulcrum hinge pin (331) in the movement of the iron groove lever mechanism (31) is determined. The long bone (310) applies downward pressure to the resistance arm of the iron groove lever mechanism (31) - the rear section (330.1) of the iron groove. The power arm of the iron groove lever mechanism (31) - the front section (330.0) of the iron groove rotates downward along the lever fulcrum - the iron groove fulcrum hinge pin (331). The main spring (240) applies a downward force to the lower nest (280), driving the front section (330.0) of the iron groove to rotate downward. The force is greater than the resistance borne by the resistance arm - the rear section (330.1) of the iron groove. The resistance arm - the rear section (330.1) of the iron groove lever mechanism (31) tilts upward to support the long bone (310) hinged to the resistance arm - the rear section (330.1) of the iron groove. Both ends of the groove (330), namely the front section (330.0) of the iron groove and the rear section (330.1) of the iron groove, are subjected to downward pressure, and the iron groove (330) moves downward. The iron groove fulcrum hinge pin (331) serving as the fulcrum of the iron groove lever mechanism (31) is driven by the iron groove (330) to move downward. The short bone pin hole 2 (320.1) hinged to the pin hole (330.3) in the iron groove through the iron groove fulcrum hinge pin (331) also moves downward with the downward movement of the iron groove fulcrum hinge pin (331), and then drives the middle nest (290) to move downward. The downward movement of the middle nest (290) drives the large punch (250) to move downward, and at the same time, the latch pin (233) installed in the latch pin groove (290.1) of the middle nest also moves downward. The downward movement of the middle nest (290) unfolds the six-link mechanism (36) to release the elastic force of the main spring (240). During the umbrella opening movement of the iron slot lever mechanism (31), the power arm, i.e., the front section of the iron slot (330.0), is one of the connecting rods of the six-link mechanism (31). The downward rotation of the front section of the iron slot (330.0) is driven by the lower nest (280); the lower nest (280) is driven by the elastic force released downward by the main spring (240), and the downward linear displacement on the middle rod (220) is greater than the displacement length of the middle nest (280) on the middle rod (220) during the umbrella opening movement when the umbrella frame assembly mechanism (40) is unfolded.That is, during the movement of the umbrella frame assembly mechanism (40) unfolding the umbrella, the speed of the lower nest (280) moving downward is greater than the speed of the middle nest (290), and the distance between the lower nest (280) and the middle nest (290) increases as the umbrella frame assembly mechanism (40) further opens the umbrella; the two short bones (320) as two connecting rods constituting the six-bar linkage (36) are moved downward by the downward pressure applied by the two correspondingly hinged long bones (310), the two iron groove front sections (330.0) as two connecting rods constituting the six-bar linkage (36) rotate downward and move downward, and the lower nest (280) as two connecting rods constituting the six-bar linkage A connecting rod of the rod mechanism (36) moves straight down along the middle rod (220). The middle nest (290), as a connecting rod constituting the six-link mechanism (36), is driven by the short bone (320) and also moves straight down along the middle rod (290). According to the hinge relationship between the connecting rods, the speed of the lower nest (280) moving downward is greater than that of the middle nest (290). The distance between the lower nest (280) and the middle nest (290) on the middle rod (220) becomes larger and larger, turning from A to B, and the main spring (240) located between the middle rod (220), the large punch (250) and the lower nest (280) releases its elastic force. When the umbrella frame assembly mechanism (40) is performing the umbrella opening movement, the iron groove lever mechanism (31) performs the lever movement to pry the long bone (310) to open the umbrella surface, and the rotation and linear displacement movement performed by each link of the six-link mechanism (36) releases the elastic force of the main spring (240). As the elastic force released downward by the main spring (240) drives the umbrella frame assembly mechanism (40) to move downward, the middle nest (290) moves downward to drive the component of the long-distance thrust mechanism (23) - the latch (233) to move further downward, and the long-distance thrust mechanism (23) transmits the downward thrust driven by the middle nest (290) downward, folding the scissor-fork linkage mechanism (17), and the scissor-fork lever mechanism (15) also opens as the scissor-fork linkage mechanism (17) is folded, so as to be pressed when closing the umbrella next time. When the component of the long-distance thrust mechanism (23) - the latch pin (233) slides in the middle rod latch pin slot (220.1) to the bottom edge (220.3) of the middle rod latch pin slot, it is limited, the middle nest (220) no longer moves downward, and the short bone (320) and the lower nest (280) are pulled downward, and the umbrella canopy is fully unfolded.

[0058] When the latch pin (233) moves to the bottom edge (220.3) of the middle rod latch pin slot and is limited, the impact mechanism (25) clamps the large punch (250) on the middle rod (220). The umbrella frame assembly mechanism (40) moves upward under the power provided by the scissor-type fulcrum movable lever mechanism (20) through the upward transmission of the long-distance thrust mechanism (23) to close the umbrella surface; after pressing the button (110), the elastic force released by the main spring (240) drives the umbrella frame assembly mechanism (40) to open the umbrella, driving the long bone (310) to open, and the downward thrust of the lower nest (280) and the middle nest (290) is transmitted by the long-distance thrust mechanism (23) to fold the scissor-type connecting rod mechanism (17), open the scissor-type lever mechanism (15), and after the latch (233) is limited in the middle rod latch slot (220.1), the umbrella surface is fully opened. The umbrella frame assembly mechanism (40) closes the umbrella under the power provided by the human hand, and uses the elastic force released by the main spring (240) to open the umbrella frame.

[0059] The impulse mechanism (25) includes the large punch (250), the bayonet (260), the bayonet spring (261), the relay rod (231), the main spring (240), the middle nest (290), the lower nest (280), the iron groove (330), the short bone (320), the middle rod, the long-distance thrust mechanism (23), the scissor-type pivot movable lever mechanism (20) and other components. Please refer to Figure 4 , Figure 5 , Figure 8 , Fig.11 , Fig.12 , Fig.14The large punch (250) is sleeved on the middle rod (220), located between the middle nest (290) and the main spring (240), and slides along the middle rod (220); the bayonet (260) slides in the large punch bayonet slot (250.0), and is always pressed toward the middle rod (220) by the pressure of the bayonet spring (261), and the bayonet thrust surface (260.2) is provided on the bayonet (260) for limiting; the bayonet spring (261) is installed on the large punch spring slot (250.4), and the elastic force provided by the bayonet spring (261) keeps the bayonet (260) under the pressure of sliding in the direction of the middle rod (220); the main spring (240) is seated on the lower nest ear hole (280.1), and is located below the large punch (250). The impulse mechanism (25) performs an umbrella opening movement: after the button (110) is pressed, the hook (260) is unhooked from the fixed hinge pin 1 (191), the elastic force of the main spring (240) is released, and the umbrella frame assembly mechanism (40) performs an umbrella opening movement. When the umbrella frame assembly mechanism (40) performs an umbrella opening movement, the middle nest (290) moves downward, causing the large punch (250) to slide downward along the middle rod (290), and the bayonet spring (261) is pushed outward by the bayonet (260), so that the bayonet spring (261) is deformed to generate elastic force, and the front arc surface (260.0) of the bayonet slides along the outer surface of the middle rod (220). The downward movement of the middle nest (290) drives the long-distance thrust mechanism (23) to perform the parachute opening movement. The component in the long-distance thrust mechanism (23) - the latch pin (233) moves downward. When the latch pin (233) slides to the edge of the bottom (220.3) of the middle rod latch pin slot, it is limited. The bayonet pin (260) is aligned with the middle rod bayonet pin hole (220.2). Under the elastic force generated by the bayonet pin spring (261) restoring its original shape, the bayonet pin (260) slides along the large punch bayonet pin slot (250.0) into the middle rod bayonet pin hole (220.2) until the bayonet pin thrust surface (260.2) limits the bayonet pin (260) from sliding further into the middle rod bayonet pin hole (220.2), thereby clamping the large punch (250) on the middle rod (220) so that it cannot slide up and down on the middle rod (220).

[0060] The impulse mechanism (25) performs the umbrella closing movement: a person manually presses the right shear rod (152) and the left shear rod (151), the scissor-type fulcrum movable lever mechanism (20) performs the umbrella closing movement, and pushes the long-distance thrust mechanism (23) to perform the umbrella closing movement; the components of the long-distance thrust mechanism (23) - the relay rod (231), the adapter block (232), and the latch (233) transmit the force of the person manually pressing the right shear rod (152) and the left shear rod (151) to the middle nest (290), push the middle nest (290) to move upward, and make the umbrella frame assembly mechanism (40) perform the umbrella closing movement. During the umbrella closing movement of the umbrella frame assembly mechanism (40), the middle nest (290) and the lower nest (280) move upward along the middle rod (220), and one end of the main spring (240) moves upward along with the upward movement of the lower nest (280); the large punch (250) is stuck on the middle rod (220) by the latch (260) and cannot slide; the other end of the main spring (240) is blocked by the large punch (250) and cannot move upward; one end of the main spring (240) moves upward while the other end cannot move, and the main spring (240) is compressed. The upward movement of the middle nest (280) causes the middle nest (290) and the large punch (250) that were originally stuck together to be pulled a distance apart, thereby forming the impact stroke C of the large punch (250); one end of the main spring (240) is blocked by the large punch (240) and cannot move upward, while the other end of the main spring (240) that moves upward with the upward movement of the lower nest (280) continues to move upward to compress the main spring (240).The relay pole (231) that moves upward in the long-distance thrust mechanism (23) moves further upward. When the relay pole circular wedge platform (231.2) moves upward and approaches the bayonet (260), the outer surface of the relay pole circular wedge platform (231.2) presses against the front end circular arc surface (260.0) of the bayonet. The upward movement curve of the outer contour of the relay pole circular wedge platform (231.2) presses against the front end circular arc surface (260.0) of the bayonet. The bayonet (260) slides outward inside and outside the large punch bayonet groove (250.0) against the elastic force of the bayonet spring (261). When the bayonet is withdrawn until the front end circular arc surface (260.0) of the bayonet contacts the wall of the middle rod bayonet hole (220.2), the arc structure surface of the front end circular arc surface (260.0) of the bayonet is subjected to the pressure of the bayonet. Due to the upward elastic force of the main spring, the front arc surface (260.0) of the bayonet pin slips off from the contact position with the wall of the bayonet pin hole (220.2) of the middle rod. Under the elastic force of the bayonet pin spring (261), the front arc surface (260.0) of the bayonet pin comes into sliding contact with the outer wall of the middle rod (220). The bayonet pin (260) completely escapes from the bayonet pin hole (220.2) of the middle rod. The large punch (250) is no longer stuck by the bayonet pin (260) and immediately rushes upward under the upward elastic force of the main spring (240). The front arc surface (260.0) of the bayonet pin rushes through the impact stroke C along the outer surface of the middle rod (220) and hits the middle nest (290). After receiving the impact force of the large punch (250), the middle nest (290) accelerates to move upward. The force applied by a person's hand to the scissor-type fulcrum movable lever mechanism (20) continues to be transmitted to the middle nest (290) through the long-distance thrust mechanism (23) until the umbrella frame assembly mechanism (40) compresses the main spring (240), and the component of the button mechanism (11) - the hook (120) hooks the fixed hinge pin 1 (191), closing the umbrella cover.

[0061] The key mechanism (11) comprises the key (110), the key spring (111), the hook (120), the hook spring (123), the hook spring pin 1 (121), the hook spring pin 2 (122), the fixed hinge pin 1 (191), the movable hinge pin 2 (192), the umbrella handle (100) and other components. Please refer to Figure 3 , Figure 6 , Fig. 9 , Fig.10The movable hinge pin 2 (192) is slidably connected to the movable pin groove (100.6) of the umbrella handle, and the movable hinge pin 2 (192) is a component of the scissor-type connecting rod mechanism (17) and also moves with the scissor-type connecting rod mechanism (17); the hook (120) is hinged to the movable hinge pin 2 (192); the hook spring pin 1 (121) is installed on the first scissor-type unit shear rod 2 (172), the hook spring pin 2 (122) is hinged to the hook spring pin hole (120.2), and one end of the hook spring (123) hooks the hook spring pin 1 (121), and the other end hooks the hook spring pin 2 (122). The button (110) slides in the button rod groove (100.7) of the umbrella handle via the button rod (110.0); the button spring (111) is sleeved on the button rod (110.0); one end of the button spring (111) is seated on the button spring seat (110.3), and the other end is blocked by the button spring seat (100.8) of the umbrella handle, so that the inward pressure of the button rod (110.0) in the button rod groove (100.7) of the umbrella handle is maintained, so that when the umbrella surface is in an open state, the button (110) faces inward and sticks to the outer surface of the umbrella handle (100). The button mechanism (11) performs an umbrella closing movement: the hook (120) moves with the movable hinge pin 1 (191), and the extension movement of the scissor-type connecting rod mechanism (17) drives the movable hinge pin 2 (192) to slide in the movable pin slot (100.6) of the umbrella handle until the hook (120) touches the fixed hinge pin 1 (191). The hook (120) rotates around the movable hinge pin 2 (192) and moves forward from the initial position under the thrust of the sliding of the movable hinge pin 2 (192), stretching the hook spring (123) until the fixed hinge pin 1 (191) falls into the hook slot (120.0). The hook spring (123) contracts to keep the fixed hinge pin 1 (191) hooked by the hook (120), so that the extended scissor-type connecting rod mechanism (17) remains in an extended state, and the elastic force of the main spring (240) cannot be released. When the hook (120) rotates and moves forward around the movable hinge pin 2 (192) under the thrust of the sliding of the movable hinge pin 2 (192), the hook (120) abuts against the button arc surface (110.1), pushes the button rod (110.0) outward from the button rod groove (100.7) of the umbrella handle, compresses the button spring (111), and the button (110) is separated from the outer surface of the umbrella handle (100) by a certain distance.

[0062] The button mechanism (11) performs an umbrella opening movement: the button (110) is pressed so that the button (110) is pressed against the outer surface of the umbrella handle (100), the button rod (110.0) moves inward in the button rod groove (100.7) of the umbrella handle, and the button arc surface (110.1) abuts against the hook (120), so that the hook (120) rotates around the movable hinge pin 2 (192), stretching the hook spring (123); when the hook groove (120.0) moves downward around the fixed pin 1 (191) hooked when opening and closing the umbrella, the hook (120) is unhooked and no longer maintains the extended state of the scissor-type connecting rod mechanism (17), the main spring (240) immediately releases the elastic force, drives the umbrella frame assembly mechanism (40) to move, and the middle nest (290) and the lower nest (280) move downward, starting the umbrella opening process. At the same time, when the hook (120) is unhooked, the hook spring (123) contracts, causing the hook (120) to return to its initial position; and the button (110), under the elastic force of the button spring (111), pushes the button rod (110.0) inwardly in the button rod groove (100.7) of the umbrella handle, causing the button (110) to stick to the outer surface of the umbrella handle (100).

[0063] In one embodiment, the umbrella handle (100) is provided with a handle longitudinal groove (100.4), a handle transverse groove (100.3), a movable pin groove (100.6), a fixed pin groove (100.5), a key rod groove (100.7), a handle middle rod seat (100.0), a relay rod through hole (100.2) and other structures, which serve as the basis of the umbrella structure. The middle rod (220) is seated on the middle rod seat (100.0) of the umbrella handle, and is key-connected or pin-connected to the middle rod fixing hole (220.0) through the umbrella handle fixing hole (100.1); the umbrella relay through hole (100.2) passes through the middle rod seat (100.0) of the umbrella handle, and the relay rod (231) passes through the hole and is connected to the conversion block (190); the umbrella handle transverse groove (100.3) is the movement space of the scissor-fork lever mechanism (15) and the scissor-fork connecting rod mechanism (17); the umbrella handle longitudinal groove (100.4) is the movement space of the scissor-fork connecting rod mechanism (17); the umbrella handle fixing pin hole (100.5) and the umbrella handle movable pin groove (100.6) are the movement space of the scissor-fork connecting rod mechanism (17 ) is connected and fixed on the basis of the umbrella handle, the umbrella handle fixed pin hole (100.5) is hinged to the front pin hole (171.0) of the first scissor unit shear rod 1 through the fixed hinge pin 1 (191), the umbrella handle movable pin groove (100.6) is slidably connected to the movable hinge pin 2 (192), and the movable hinge pin 2 (192) is hinged to the front pin hole (172.0) of the first scissor unit shear rod 2; the umbrella handle button rod groove (100.7) is equipped with the button rod (110.0), and the button rod (110.0) slides in the umbrella handle button rod groove (100.7), and the umbrella handle button spring seat (100.8) is also provided in the umbrella handle button rod groove (100.7), and one end of the button spring (111) is seated here. Please refer to Figure 3 , Figure 6 , Fig. 9 , Fig.10 .

[0064] In one embodiment, the button (110) is provided with the button rod (110.0), the button arc surface (110.1), and the button spring seat (110.3), and the button (110) is slidably connected to the button rod groove (100.7) of the umbrella handle through the button rod (110.0). The button spring (111) is sleeved on the button rod (110.0) and one end is seated on the button spring seat (110.3), and the other end is seated on the button spring seat (100.8) of the umbrella handle. When the umbrella is in the open state, one end of the button spring (111) is seated on the umbrella handle button spring seat (100.8), which is the fixed end of the button spring (111) for release. The other end of the button spring (111) presses against the button spring seat (100.3), so that the button rod (100.0) slides into the umbrella handle (100) in the umbrella handle button rod groove (100.7), and the button (110) is attached to the outer surface of the umbrella handle (100). In the closed state, the hook (120) presses against the button arc surface (110.1), so that the button rod (110.0) slides outward in the umbrella handle button rod groove (100.7), and the button (110) is separated from the outer surface of the umbrella handle (100) by a distance, so as to facilitate manual pressing to start the umbrella opening process. Please refer to Figure 3 , Figure 6 , Fig. 9 , Fig.10 .

[0065] In one embodiment, the button spring (111) is sleeved on the button rod (110.0), one end of which is seated on the button spring seat (100.8) of the umbrella handle, and the other end of which is seated on the button spring seat (110.3). The elastic force released by the button spring (111) keeps the button (110) against the outer surface of the umbrella handle (100) in the umbrella opening state, so that during the umbrella closing process, the hook (120) pushes the button rod (110.0) out of the outer surface of the umbrella handle (100), presenting two different states of umbrella opening and umbrella closing. Figure 3 , Figure 6 , Fig. 9 , Fig.10 .

[0066] In one embodiment, the hook spring pin 1 (121) is installed on the shear rod 2 (172) of the first scissor fork unit, and the hook spring pin 2 (122) is hinged to the hook spring pin hole (120.2). The two ends of the hook spring (123) respectively hook the hook spring pin 1 (121) and the hook spring pin 2 (122). Please refer to Figure 3 , Figure 6 , Fig. 9 , Fig.10 .

[0067] In one embodiment, the hook (120) is provided with the hook groove (120.0), the hook pin hole (120.1), and the hook spring pin hole (120.2); one end of the hook spring (123) is hooked on the hook spring pin 1 (121), and the other end is hooked on the hook spring pin 2 (122); the hook pin hole (120.1) is hinged to the movable hinge pin 2 (192); during the umbrella closing process, the hook (120) moves along with the movable hinge pin When the movable hinge pin 2 (192) slides, the hook (120) contacts the fixed hinge pin 1 (191) and then rotates to avoid and stretch the hook spring (123). After avoiding the fixed hinge pin 1, the hook spring (123) contracts to pull the hook (120) back to the position before rotation. In this state, the hook groove (120.0) hooks the fixed hinge pin 1 (191), and the hook (120) is hinged to the movable hinge pin 2 (192). The movable hinge pin 2 (192) is hinged to the scissor rod 2 (172) of the first scissor unit of the scissor-type linkage mechanism (17) and the sliding movement made in the movable pin groove (100.6) of the umbrella handle is pulled by the hook (120) and cannot slide anymore. When the umbrella is closed, the scissor-type linkage mechanism (17) is an extended movement. After the movable hinge pin 2 (192) is pulled by the hook (120), the extended state of the scissor-type linkage mechanism (17) is maintained. When the hook (120) contacts the fixed hinge pin 1 (191) and rotates away, the hook (120) contacts the button arc surface (110.1), causing the button rod (110.0) to slide in the button rod groove (100.7) of the umbrella handle, and the button (110) changes from being attached to the outer surface of the umbrella handle (100) in the umbrella opening state to being separated from the outer surface of the umbrella handle (100). When the umbrella is closed, the hook (120) maintains the extended state of the scissor-type connecting rod mechanism (17) unchanged, and maintains the closed state of the umbrella surface unchanged. When the parachute is opened, the button is pressed by hand, the button rod (110.0) rotates against the hook groove (120.0), disengages from the fixed hinge pin 1 (191), and the extended state maintained by the scissor-type linkage mechanism (17) becomes invalid. Under the release of the elastic force of the main spring (240), the scissor-type linkage mechanism (17) folds, and after the hook (120) is disengaged from the fixed hinge pin 1 (191), the hook spring (123) contracts again to pull the hook (120) back to the position before rotation, and the hook (120) slides with the movable hinge pin 2 (192). Please refer to Figure 3 , Figure 6 , Fig. 9 , Fig.10 .

[0068] In one embodiment, one end of the hook spring (123) hooks the hook spring pin 1 (121), and the other end hooks the hook spring pin 2 (122), providing a fixed position for the hook (120) when the hook (120) is not rotating, and stretching the hook spring (123) when the hook (120) is blocked from moving and rotates to avoid resistance; after the hook (120) moves to avoid resistance, the hook spring (123) pulls the hook (120) back to a fixed position.

[0069] In one embodiment, the scissor-type linkage mechanism (17) is composed of a plurality of groups of scissor-type units consisting of two or more connecting rods of the same size, equidistant symmetry, and similar motion, which are connected in series in sequence. The scissor-type linkage mechanism can complete the displacement of linear motion through the extension and folding of the scissor-type linkage mechanism, and is a linear motion mechanism.

[0070] In one embodiment, the scissor-type lever mechanism (15) comprises the first scissor-fork unit (170), a left shear rod (151), a right shear rod (152), a shear rod fulcrum hinge pin (153), a left shear rod resistance arm pin (154), and a right shear rod resistance arm pin (155). The left shear rod middle pin hole (151.0) and the right shear rod middle pin hole (152.0) are hinged through the shear rod fulcrum hinge pin (153), the left shear rod bottom pin hole (151.2) and the first scissor-fork unit shear rod 1 tail pin hole (171.2) are hinged through the left shear rod resistance arm pin (154), and the right shear rod bottom pin hole (152.2) and the first scissor-fork unit shear rod 2 tail pin hole (172.2) are hinged through the right shear rod resistance arm pin (155). The left shear rod (151) and the right shear rod (152) are connected in a scissor-fork manner and are hinged with the shear rod fulcrum hinge pin (153). The right shear rod (152) is divided into the right shear rod resistance arm (152.5) ​​of the right shear rod power arm (152.1) with the shear rod fulcrum hinge pin (153) as a fulcrum. The left shear rod (151) is divided into the left shear rod resistance arm (151.5) of the left shear rod power arm (151.1) with the shear rod fulcrum hinge pin (153) as a fulcrum. The first scissor-fork unit (170) is a group of connecting rod mechanisms, which are the objects to be pried by the scissor-fork lever mechanism (15). The first scissor-fork unit (170) is a part of the movement of the scissor-fork connecting rod mechanism (17). When the left shear rod (15) and the right shear rod (152) are pressed to pry the first scissor-fork unit (170), the first scissor-fork unit (170) serves as a basic component for installing the scissor-fork lever (15). The extension movement trajectory of the first scissor-fork unit (170) is to rise while sliding horizontally, thereby driving the movement of the shear rod fulcrum hinge pin (153) at which the left shear rod (151) and the right shear rod (152) are hinged, that is, driving the movement of the fulcrum of the scissor-fork lever mechanism (15). The right shear rod (152) is provided with a right shear rod movable pin track groove (152.3) and a right shear rod fixed pin track groove (152.4), the movable hinge pin 3 (193) moves in the right shear rod movable pin track groove (152.3), and the fixed hinge pin 4 (194) moves in the right shear rod fixed pin track groove (152.4); the left shear rod (151) is provided with a left shear rod movable pin track groove (151.3) and a left shear rod fixed pin track groove (151.4), the movable hinge pin 3 (193) moves in the left shear rod movable pin track groove (151.3), and the fixed hinge pin 4 (194) moves in the left shear rod fixed pin track groove (151.4). The movable hinge pin 3 (193) is hinged to the end pin hole (181.2) of the shear rod 1 of the end scissor fork unit, and the fixed hinge pin 4 (194) is hinged to the end pin hole (182.2) of the shear rod 2 of the end scissor fork unit.When the left shear rod (151) is pressed and the right shear rod (152) pries the first scissor-fork unit (170) up and slides laterally by lever principle, driving the scissor-fork type connecting rod mechanism (17) to extend, the right shear rod movable pin track groove (152.3) laterally squeezes the movable hinge pin 3 (193), the right shear rod fixed pin track groove (152.4) lifts the fixed hinge pin 4 (194), the left shear rod fixed pin track groove (151.4) laterally squeezes the fixed hinge pin 4 (194), and the left The shear rod movable pin track groove (151.3) lifts the movable hinge pin 3 (193), presses the fixed hinge pin 4 (194) and the movable hinge pin 3 (193) laterally, and lifts the fixed hinge pin 4 (194) or the movable hinge pin 3 (193) longitudinally, all of which apply a driving force to the extension movement of the end of the scissor-type linkage mechanism (17), while pressing the left shear rod (151) and the right shear rod (152) to pry the first scissor-type unit (170) is a driving force applied to the extension of the head end of the scissor-type linkage mechanism (17). Please refer to. Figure 3 , Figure 6 , Fig. 9 , Fig.10 , Fig.13 .

[0071] In one embodiment, the conversion block (190) is provided with the conversion block fixed hinge pin hole (190.0), movable hinge pin slot (190.1), connection hole (190.2), and shear rod movable slot (190.3). The conversion block fixed hinge pin hole (190.0) is hinged to the fixed hinge pin 3 (193), the conversion block movable hinge pin slot (190.1) is hinged to the movable hinge pin 4 (194), and the scissor-type linkage mechanism end scissor unit (180) moves in the conversion block shear rod movable slot (190.3). The conversion block is the output platform of the movement of the scissor-type linkage mechanism (17), which converts the extension and folding linear motion of the scissor-type linkage mechanism into the linear displacement of the platform. Please refer to Figure 3 , Figure 6 , Fig. 9 , Fig.10 .

[0072] In one embodiment, the relay rod (231) is located inside the middle rod (220), connecting the upper and lower parts for long-distance force transmission. The relay rod connection hole 1 (231.0) is connected to the conversion block connection hole (190.2) at the bottom, and the relay rod connection hole 2 (231.1) is connected to the transfer block connection hole (232.0) at the top. When closing the umbrella, the transfer block (190) converts the extension movement of the scissor-type connecting rod mechanism (17) into the thrust of the linear movement of the platform, which is transmitted to the transfer block (232); when opening the umbrella, the elastic force released by the main spring (240) on the umbrella frame assembly mechanism (40) is received and transmitted downward to the transfer block (190), and then the transfer block (190) converts the linear movement of the platform into the folding movement of the scissor-type connecting rod mechanism (17). The relay pole (231) is also provided with the relay pole circular wedge platform (231.2). When the parachute is closed, the relay pole (231) is pushed upward by the conversion block (190), and the latch pin (260) is pressed by the latch pin spring (261) to be inserted into the middle rod latch pin hole (220.2) to latch the large punch (250). When the relay pole (231) is pushed upward, the surface of the relay pole circular wedge (231.2) contacts the front arc surface (260.0) of the bayonet pin, pushing the bayonet pin (260) outward of the middle rod (220); when the front arc surface (260.0) of the bayonet pin contacts the bayonet pin hole (220.2) of the middle rod, the front arc surface (260.0) of the bayonet pin cannot withstand the elastic force of the compression of the main spring (240), and the front arc surface (260.0) of the bayonet pin slides out of the middle rod (220) from the bayonet pin hole (220.2), so that the large punch (250) is no longer stuck in the bayonet pin hole (220.2) of the middle rod by the bayonet pin (260). The relay pole circular wedge (231.2) is adapted to the travel of the relay pole (231) and the position of the latch pin (260) being inserted into the middle rod latch pin hole (220.2). The two components slide and move, and the latch pin (260) is pushed out of the middle rod latch pin by the motion curve of the outer contour of the relay pole circular wedge (231.2). Figure 4 , Figure 5 , Figure 7 , Figure 8 , Fig.11 , Fig.12 .

[0073] In one embodiment, the adapter block (232) is provided with the adapter block pin slot (232.1) and the adapter block connection hole (232.0). The relay pole connection hole 2 (231.1) is connected to the adapter block connection hole (232.0), and the pin (233) is inserted into the adapter block pin slot (232.1). The adapter block (232) cooperates with the pin (233) to convert the motion state of the relay pole (231) inside the middle rod (220) into the motion outside the middle rod (220) when closing the parachute; and to convert the motion state of the middle nest (290) outside the middle rod (220) into the motion of the relay pole (231) inside the middle rod (220) when opening the parachute, that is, according to the different force-bearing bodies, the motion relationship of the motion components inside and outside the middle rod (220) is following and linked. The following of the two moving parts inside and outside the middle rod is not limited to the connection relationship between the two moving parts being a direct contact fixed connection. The mutual attraction of the two components through magnetism also belongs to the mutual following movement of the two objects.

[0074] In one embodiment, the latch (233) is inserted into the adapter block latch slot (232.1) in the middle rod (220), passes through the adapter block (232), and then passes through the middle rod latch slot (220.1). A portion of the latch (233) is exposed outside the middle rod (220), and the portion of the latch (233) outside the middle rod (220) is fixed in the middle nest latch nest (290.1). The latch (233) slides along the middle rod latch slot (290.1). The coordination between the adapter block (232) and the latch (233) enables the movement relationship of the moving components inside and outside the middle rod (220) to follow and link.

[0075] In one embodiment, the middle rod (220) is provided with the middle rod fixing hole (220.0), the middle rod pin slot (220.1), the middle rod latching hole (220.2), and the bottom edge (220.3) of the middle rod pin slot. The lower end of the middle rod (220) is fixed to the umbrella handle middle rod fixing seat (100.0), and is pin-keyed to the umbrella handle fixing hole (100.1) through the middle rod fixing hole (220.0). The upper nest fixing hole (300.4) is inserted into the middle rod (220), and is pin-keyed to the middle rod fixing hole (220.0) through the upper nest fixing hole (300.4). The middle rod (220) is hollow, and the relay rod (231), the adapter block (232), and the pin (233) move inside it. The latch (233) passes through the middle rod latch slot (220.1) and is slidably connected along the middle rod latch slot (220.1). When the umbrella is fully opened, the latch (233) is limited when it slides along the middle rod latch slot (220.1) to the bottom edge (220.3) of the middle rod latch slot, setting the position where the umbrella is fully opened. The middle rod bayonet hole (220.2), when the umbrella is opened, the bayonet (260) moves to the middle rod bayonet hole (220.2) with the large punch (250), and is inserted into the middle rod bayonet hole (220.2) under the pressure of the bayonet spring (261), fixing the movement of the large punch (250) on the middle rod (220).

[0076] In one embodiment, the lower nest (280) is sleeved outside the middle rod (220), and is provided with a lower slot iron slot (280.0), a lower slot ear hole (280.1), a lower slot through hole (280.2), and a lower slot iron wire slot (280.3). The middle rod (220) passes through the lower nest through hole (280.2), the lower nest (280) slides on the middle rod (220), the iron slot (330) is installed in the lower nest iron slot (280.0), and is hingedly fixed to the lower nest iron wire slot (280.3) through the lower nest iron wire (281). The lower nest (280), the middle nest (290), the short bone (320), and the front section of the iron slot (330.0) form a motion relationship of a six-bar linkage (36). The main spring (240) is seated in the lower nest ear hole (280.1). When closing the umbrella, the lower nest (280) pulls up the front section (330.0) of the iron groove; when opening the umbrella, the front section (330.0) of the iron groove is pulled down, so that the iron groove (330) rotates around the iron groove fulcrum hinge pin (331).

[0077] In one embodiment, the iron trough (330) is provided with an iron trough front pin hole (330.2), an iron trough middle pin hole (330.3), and an iron trough tail pin hole (330.4). The iron trough middle pin hole (330.3) divides the iron trough (330) into the iron trough front section (330.0) and the iron trough rear section (330.1). The iron trough front pin hole (330.2) is hinged to the lower nest wire trough (280.3) through the lower nest wire (281). The iron trough middle pin hole (330.3) is hinged to the short bone pin hole 2 (320.1) through the iron trough fulcrum hinge pin (331). The iron trough tail pin hole (330.4) is hinged to the short bone pin hole 2 (320.1) through the iron trough fulcrum hinge pin (331). The hole (330.4) is hinged to the middle joint (310.2) of the long bone. When the umbrella is closed, the iron groove fulcrum hinge pin (331) hinged to the short bone pin hole 2 (320.1) moves upward along with the upward movement of the short bone (320). The upward movement of the iron groove fulcrum hinge pin (331) drives the iron groove (330) to move upward. At this time, the rear section (330.1) of the iron groove is subjected to the downward pressure of the long bone (310). The rear section (330.1) of the iron groove rotates downward around the iron groove fulcrum hinge pin (331); the front section (330.0) of the iron groove rotates upward around the iron groove fulcrum hinge pin (331). The front pin hole (330.2) of the iron groove and the lower groove iron wire (281) are hinged on the lower nest iron wire groove (280.3). The upward rotation of the front section (330.0) of the iron groove drives the lower nest (280) to move upward along the middle rod (220). When the umbrella is opened, the main spring (240) in the umbrella frame assembly mechanism (40) uses the end in contact with the large punch (250) as a fixed end, releases the elastic force downward, and the lower nest (280) moves downward, driving the front section (330.0) of the iron groove hinged on the lower nest (280) to move downward. The middle nest (290) is still in the state where the main spring (240) is released. On the fixed side of the elastic force release device, the short bone pin hole 1 (320.0) end is hinged on the middle nest (290), and the short bone pin hole 2 (320.1) is hinged with the iron trough middle pin hole (330.3) through the iron trough fulcrum hinge pin (331). The short bone (320) pulls the middle part of the iron trough (330) downward by pulling the iron trough fulcrum hinge pin (331), and the front section (330.0) of the iron trough is driven downward by the lower nest (280), so that the iron trough (330) rotates around the iron trough fulcrum hinge pin (331), and the rear section (330.1) of the iron trough is tilted upward to support the long bone (310).When the long bone (310) is propped up, the pressure is applied in reverse to the rear section (330.1) of the iron groove. The rear section (330.1) of the iron groove is under pressure, and the front section (330.0) of the iron groove is also pulled downward by the lower nest (280), pulling the short bone (320) of the iron groove fulcrum hinge pin (331). Under the action of the downward force on the front section (330.0) and the rear section (330.1) of the iron groove, the middle nest (290) is driven to move downward, and the large punch (250) moves downward with the middle nest (290). As the angle of the long bone (310) is increased, the main spring (240) drives the lower nest (280) to move downward. Until the latch pin (233) slides to the bottom edge along the middle rod latch pin slot (220.1) and is limited, the long bone (310) is fully opened, and the umbrella cover is opened. The iron groove (330) rotates around the iron groove fulcrum hinge pin (331), the front section (330.0) of the iron groove rotates downward, and the rear section (330.1) of the iron groove rotates upward, supporting the long bone (310) to open; the front section (330.0) of the iron groove rotates upward, and the rear section (330.1) of the iron groove rotates downward, closing the long bone (310) to achieve the opening and closing of the umbrella. Please refer to. Figure 1 , Figure 4 , Figure 7 , Figure 8 .

[0078] In one embodiment, the middle nest (290) is provided with a middle nest short bone groove (290.0), a middle nest latch groove (290.1), a middle nest through hole (290.2), and a middle nest wire groove (290.3). The middle nest (290) is sleeved on the middle rod (220) through the middle nest through hole (290.2); the short bone (320) is installed in the middle nest short bone groove (290.0), and is hinged with the short bone pin hole 1 (320.0) through the middle nest iron wire (291) and fixed to the middle nest iron wire groove (290.3); the short bone pin hole 2 (320.1) is hinged with the iron groove middle pin hole (330.3) through the iron groove fulcrum hinge pin (331); the plug (233) passes through the middle rod plug pin groove (220.1) exposed outside the middle rod (220) and is fixed to the middle nest plug pin groove (290.1). The large punch (250) is sleeved on the middle rod (220), below the middle nest (290), and above the main spring (240). When the umbrella is closed, the relay rod (231) of the long-distance thrust mechanism (23) transmits the force of the scissor-type fulcrum movable lever mechanism (20) to the middle nest (290), pushing the middle nest (290) upward, driving the short bone (320) upward, and the front section (330.0) of the iron groove is pulled upward by the short bone (320), driving the lower nest (280) to rise, and the rear section (330.1) of the iron groove is pressed down by the long bone (310), so that the iron groove (330) rotates around the iron groove fulcrum hinge pin (331) until the umbrella surface is completely closed. When the relay rod (231) pushes the middle nest (290) to move upward, the large punch (250) is stuck on the middle rod pin hole (220.2) by the pin (260) and cannot move. When the lower nest (280) moves upward, the main spring (240) seated on the ear hole (280.1) of the lower nest also moves upward, but the large punch (250) is stuck on the middle rod pin hole (220.2), blocking the upward movement of one end of the main spring (240), and the main spring (240) is compressed. As the relay rod (231) moves further upward, the middle nest (290) and the lower nest (280) move upward. 280) moves further upward, the main spring (240) is further compressed, and the distance between the large punch (250) and the middle nest (290) becomes the impact stroke C; when the relay rod (231) moves upward to the relay rod circular wedge platform (231.2) to push out the latch pin (260) stuck in the middle rod latch pin hole (220.2), the large punch (250) is no longer stuck by the latch pin (260), and the elastic force applied by the main spring (240) on the large punch (250) immediately pushes the large punch (250) upward, passes the impact stroke C, and hits the middle nest (290).The middle nest (290) hit by the large punch (250) moves upward at an accelerated speed, supplementing the thrust provided by the scissor-type pivot movable lever mechanism (20). The middle nest (290) enters the upper nest ear hole (300.1) in whole or in part after the umbrella is folded.

[0079] In one embodiment, the short bone (320) is provided with a short bone pin hole 1 (320.0) and a short bone pin hole 2 (320.1), the short bone pin hole 1 (320.0) is hinged to the middle nest iron wire nest (290.3) through the middle nest iron wire (291), and the short bone pin hole 2 (320.1) is hinged to the iron slot middle pin hole (330.3) through the iron slot fulcrum hinge pin (331). When the umbrella is closed, the short bone (320) moves upward along with the middle nest (290), pulling the iron slot fulcrum hinge pin (331) to move upward. The iron groove fulcrum hinge pin (331) is hinged on the pin hole (330.3) in the iron groove. The two ends of the iron groove (330) are subjected to unbalanced forces and begin to rotate. The upward movement of the iron groove fulcrum hinge pin (331) causes the rear section (330.1) of the iron groove to be subjected to pressure from the long bone (310). Under the downward pressure of the long bone (310), the short bone (320) pulls the iron groove fulcrum hinge pin (331) upward, causing the front section (330.0) of the iron groove to tilt upward, thereby driving the lower nest (280) to move upward along the middle rod (220), thereby achieving the closure of the umbrella surface. When the umbrella is opened, the lower nest (280) moves downward, driving the front section (330.0) of the iron groove to move downward, the short bone (320) pulls the iron groove fulcrum hinge pin (331), the iron groove (330) rotates around the iron groove fulcrum hinge pin (331), the front section (330.0) of the iron groove moves downward with the lower nest (280), and the rear section (330.1) of the iron groove rises around the iron groove fulcrum hinge pin (331), propping up the long bone (310). When the short bone (320) is opening or closing the umbrella, the iron groove (330) is pulled upward by the iron groove fulcrum hinge pin (331), causing the two ends of the iron groove (330) to lose balance and start to rotate, thereby realizing the opening and closing of the long bone (310).

[0080] In one embodiment, the large punch (250) is provided with a large punch latch groove (250.0), a large punch latch seat (250.1), a large punch through hole (250.2), a large punch guide column (250.3), and a large punch spring groove (250.4). The large punch (250) is sleeved on the middle rod (220) through the large punch through hole (250.2), below the middle nest (290) and above the main spring (240); the main spring (240) is sleeved on the large punch guide column (250.3) to avoid friction when the wire diameter of the main spring (240) slides on the middle rod (220); the bayonet (260) is inserted into the large punch bayonet groove (250.0) and is slidably connected to the large punch bayonet groove (250.0); the bayonet spring (261) is wound in the large punch spring groove (250.4) and presses the bayonet spring groove (260.1) by elastic force, so that the bayonet (260) maintains the force of sliding inward. When the umbrella is closed, one end of the large punch (250) abuts against the main spring (240), and the other end is close to one side of the middle nest (290). Therefore, the latch pin (260) is aligned with the middle rod latch pin hole (220.2) in the large punch latch pin groove (250.0), and under the elastic force of the latch pin spring (261), the latch pin (260) is inserted into the middle rod latch pin hole (220.2), so that the large punch (250) is latched on the middle rod (220). When the umbrella closing power provided by the scissor-type fulcrum movable lever mechanism (20) is transmitted through the long-distance thrust mechanism (23), the relay rod (231) component in the long-distance thrust mechanism (23) moves upward, and the long-distance thrust mechanism (23) pushes the middle nest (290) to move upward. The upward movement of the middle nest (290) drives the lower nest (280) to move upward, and the main spring (240) moves upward along with the upward movement of the lower nest (280). One end of the main spring (240) is resisted by the large punch (250), and the large punch (250) is stuck in the middle rod pin hole (220.2). The other end of the main spring (240) moves upward along with the upward movement of the lower nest (280), and the main spring (240) is compressed. At the same time, the middle nest (290) still moves upward under the thrust of the long-distance thrust mechanism (23), and the large punch (250) is stuck on the middle rod pin hole (220.2) and cannot slide, so a distance is pulled between the middle nest (290) and the large punch (250), forming an impact stroke C.When the relay pole circular wedge (231.2) moves further upward and the outer surface of the relay pole circular wedge (231.2) presses against the front end circular arc surface (260.0) of the bayonet pin, the upward movement curve of the outer contour of the relay pole circular wedge (231.2) presses against the front end circular arc surface (260.0) of the bayonet pin, and the bayonet pin (260) slides outwards inside and outside the large punch bayonet pin groove (250.0) against the elastic force of the bayonet pin spring (261). When the front end circular arc surface (260.0) of the bayonet pin contacts the wall of the middle rod bayonet pin hole (220.2), the arc structure surface of the front end circular arc surface (260.0) of the bayonet pin bears the upward force of the main spring (240). The front arc surface (260.0) of the bayonet pin slips off from the contact position with the wall of the bayonet pin hole (220.2) of the middle rod under the elastic force of the bayonet pin spring (261), and the front arc surface (260.0) of the bayonet pin comes into sliding contact with the outer wall of the middle rod (220) under the elastic force of the bayonet pin spring (261), and the bayonet pin (260) completely slides out of the bayonet pin hole (220.2) of the middle rod. The large punch (250) immediately rushes upwards under the upward elastic force of the main spring (240), rushes through the impact stroke C, and hits the middle nest (290). After receiving the impact force of the large punch (250), the middle nest (290) accelerates to move upwards, driving the umbrella frame assembly mechanism (40) to close the umbrella surface. When the umbrella is opened, after the brown button (110) is pressed, the hook (120) of the button mechanism (11) is unhooked from the fixed hinge pin 1 (191), so that the scissor-type connecting rod mechanism (17) no longer maintains the extended state, and the umbrella frame assembly mechanism (40) is released by the positive elastic force of the main spring (240), and the lower nest (280) moves downward, driving the front section (330.0) of the iron groove to move downward, and the iron groove (330) rotates around the iron groove fulcrum hinge pin (331) under the pull of the short bone (320), and the rear section (330.1) of the iron groove is tilted upward to support the long bone (310). The downward movement of the lower nest (280) drives the downward movement of the middle nest (290), and the large punch (250) moves downward along with the downward movement of the middle nest (290) until the latch (233) slides to the bottom edge along the middle rod latch slot (220.1) and is limited, and the bayonet (260) is aligned with the middle rod bayonet hole (220.2) in the large punch bayonet slot (250.0). Under the elastic force of the bayonet spring (261), the bayonet (260) is inserted into the middle rod bayonet hole (220.2), and the large punch (250) is stuck on the middle rod (220) and cannot slide along the middle rod (220).The latch (260) is a component of the impact mechanism (25). The impact mechanism (25) compresses the main spring (240) to create the impact stroke C, and then releases the elastic force of the main spring (240) and applies it to the large punch (250). The large punch (250) that bears the released elastic force of the main spring (240) impacts upward, passes through the impact stroke C, and hits the middle nest (290), thereby supplementing the power provided by the scissor-type fulcrum movable lever mechanism (20).

[0094] Fig. 9 for Figure 7Sectional view of the scissor-type lever mechanism. The left picture is a center section, showing the inside of the scissor-type lever mechanism, and the right picture is a section view after the offset section, which is convenient for seeing the external structure of the scissor-type lever mechanism. The scissor-type fulcrum movable lever mechanism (20) drives the long-distance thrust mechanism (23) to move upward, pushing the umbrella frame assembly mechanism (40) to close the umbrella surface. When the umbrella surface reaches the final closing stage, the fixed hinge pin 3 (193) slides along the left shear rod fixed pin track groove (151.4) and the right shear rod fixed pin track groove (152.4); the movable hinge pin 4 (194) slides along the right shear rod movable pin track groove (152.3) and the left shear rod movable pin track groove (151.3). The left shear rod movable pin track groove (151.3), the left shear rod fixed pin track groove (151.4), the right shear rod movable pin track groove (152.3), and the right shear rod fixed pin track groove (152.4) are all motion curves. The upward movement of the fixed hinge pin 3 and the movable hinge pin 4 along the motion curve track squeezes the fixed hinge pin 3 and the movable hinge pin 4, driving the scissor-type connecting rod mechanism (17) to extend; the downward movement of the fixed hinge pin 3 and the movable hinge pin 4 along the motion curve track pushes the fixed hinge pin 3 and the movable hinge pin 4 outward to both sides, driving the scissor-type connecting rod mechanism (17) to fold. When the power arms of the scissor-type lever mechanism (15) are closed inwardly, the resistance arms are also closed mutually, squeezing the shear rods of the first scissor-type unit (170) and the second scissor-type unit (176) of the scissor-type connecting rod mechanism (17) to stretch, thereby exerting a squeezing force on the head end of the scissor-type connecting rod mechanism (17); the last scissor-type unit (180) stretches along with the stretching of the scissor-type connecting rod mechanism (17), and the fixed hinge pin 3 and the movable hinge pin 4 move upward along with the stretching of the last scissor-type unit. The fixed hinge pin 3 and the movable hinge pin 4 bear the force of the left shear rod power arm (151.1) and the right shear rod power arm (152.1) closing together, and move along the motion curve track formed by the left shear rod movable pin track groove (151.3), the left shear rod fixed pin track groove (151.4), the right shear rod movable pin track groove (152.3), and the right shear rod fixed pin track groove (152.4), which is an extrusion force applied to the end of the scissor-type connecting rod mechanism (17). The scissor-type lever mechanism (15) realizes the extrusion of the head and the tail of the scissor-type connecting rod mechanism (17) in the process of driving the scissor-type connecting rod mechanism (17) to extend, thereby achieving a labor-saving effect.

[0095] See also Fig.10 ,for Figure 7 Front sectional view of the umbrella handle. The button mechanism (11) is in a state of maintaining the scissor-type connecting rod mechanism (17) extended.

[0096] See also Fig.11 ,for Figure 7 A side cross-sectional view of an umbrella frame. The latch (260) of the impulse mechanism (25) slides along the outer surface of the middle rod (220).

[0097] See also Fig.12 , is a schematic diagram of the impact stroke during the umbrella closing process. The latch pin (260) of the impact mechanism (25) is still stuck in the middle rod latch pin hole (220.2), the lower nest (280) and the middle nest (290) are both in the process of moving upward, and the large punch (250) cannot move, forming an impact stroke.

[0098] The process of closing the umbrella is as follows:

[0099] like Figure 6 As shown, a person manually presses the left shear bar power arm (151.1) and the right shear bar power arm (152.1), and the left shear bar resistance arm (151.5) and the right shear bar resistance arm (152.5) ​​approach to compress the two shear bars of the scissor-fork type connecting rod mechanism (17). The shear bars of the scissor-fork type connecting rod mechanism (17) are extended by the extrusion force on both sides.

[0100] like Figure 4 As shown, the component relay rod (231) of the long-distance thrust mechanism (23) connected to the upper end of the scissor-type connecting rod mechanism (17) rises, and the long-distance thrust mechanism (23) begins to transmit the force of the scissor-type fulcrum movable lever mechanism (20).

[0101] like Figure 4 As shown, the component latch (233) of the long-distance thrust mechanism (23) is fixed in the middle nest latch groove (290.1), and the long-distance thrust mechanism (23) moves upward, and then pushes the umbrella frame assembly mechanism (40) to close the umbrella. The iron groove lever mechanism (31) and the six-link mechanism (36) then perform the umbrella closing action.

[0102] In the initial process of the long-distance thrust mechanism (23) moving upward, if Figure 5 As shown, the impulse mechanism (25) does not move upward with the upward movement of the long-distance thrust mechanism (23), and the component latch (260) of the impulse mechanism (25) is stuck in the middle rod latch hole (220.2), so that the large punch (250) cannot move up and down on the middle rod (220), but the umbrella frame assembly mechanism (40) is subjected to the force of the long-distance thrust mechanism (23), and the lower nest (280) and the middle nest (290) are still moving upward, closing the long bone (310). The large punch (250) of the impulse mechanism (25) does not move, but only blocks the upward movement of the main spring (240). One end of the main spring (240) moves upward with the lower nest (280), and the other end is blocked by the large punch (250) and cannot move upward, thereby compressing the main spring (240).

[0103] The scissor-type pivot movable lever mechanism (20) continues to provide power, the scissor-type connecting rod mechanism (17) continues to extend, the long-distance thrust mechanism (23) continues to move upward, the lower nest (280) and the middle nest (290) of the umbrella frame assembly mechanism (40) continue to rise, the iron groove lever mechanism (31) and the six-link mechanism (36) continue to close the umbrella, and the main spring (240) continues to be compressed.

[0104] When the relay rod (231) component of the long-distance thrust mechanism (23) moves upward, the relay rod circular wedge platform (231.2) touches the front end arc surface (260.0) of the bayonet pin, and pushes the bayonet pin (260) out of the middle rod (220) as the relay rod (231) continues to move upward.

[0105] At the moment when the latch (260) is separated from the middle rod latch hole (220.2), the distance between the large punch (250) and the lower end surface of the middle nest is the impact stroke C. That is, at the moment when the latch (260) is separated from the middle rod latch hole (220.2), the impact mechanism (25) performs an upward impact process, hits the middle nest (290), and further promotes the closing process of the long bones of the umbrella frame assembly mechanism (40), until the middle nest (290) enters the upper nest ear hole (300.1), the hook (120) hooks the fixed hinge pin 1 (191), keeps the scissor-type connecting rod mechanism (17) in the extended state, and the distance between the middle nest (290) and the lower nest (280) changes from B to A, compresses the main spring (240), and the long bones (310) are closed, completing the umbrella closing process.

[0106] The parachute opening action is as follows:

[0107] The component button (110) of the button mechanism (11) is pressed to start the umbrella opening action of the button mechanism (11), the button mechanism (11) no longer maintains the extended state of the scissor-type connecting rod mechanism (17), the component main spring (240) of the umbrella frame assembly mechanism (40) releases the elastic force, driving the umbrella frame assembly to close the umbrella; the long-distance thrust mechanism (23) is affected by the elastic force released by the component main spring (240) of the umbrella frame assembly mechanism (40), and the long-distance thrust mechanism (23) starts the umbrella opening action, transmitting the umbrella The main spring (240) of the frame assembly mechanism (40) releases the elastic force; the scissor-type fulcrum movable lever mechanism (20) receives the main spring (240) of the umbrella frame assembly mechanism (40) transmitted by the long-distance thrust mechanism to release the elastic force, and the scissor-type fulcrum movable lever mechanism (20) starts the umbrella closing action; when the umbrella frame assembly mechanism (40) performs the umbrella closing action, the impulse mechanism (25) also performs the umbrella closing action, and the front arc surface (260.0) of the latch pin slides downward along the outer surface of the middle rod (220). When the component latch pin (233) of the long-distance transmission mechanism (23) slides in the middle rod latch pin groove (220.1) to the bottom edge (220.3) of the middle rod latch pin groove, the downward movement is limited, and the long-distance thrust mechanism (23) no longer moves downward, and the umbrella opening action is completed.

[0108] The component latch (260) of the impulse mechanism (25) is aligned with the middle rod latch hole (220.2). Under the elastic force of the latch spring (261), the latch (260) is inserted into the middle rod latch hole (220.2), and the impulse mechanism completes the umbrella opening action; the distance between the middle nest (290) and the lower nest (280) is changed from B to A; the scissor-type fulcrum movable lever mechanism (20) completes the umbrella opening action, and the scissor-type connecting rod mechanism (17) is in the long-distance thrust The scissor-type lever mechanism folds under the downward force of the mechanism (23), and along with the folding of the scissor-type connecting rod mechanism (17), the left scissor-type power arm (151.1) and the right scissor-type power arm (152.1) open; the component long bone (310) of the umbrella frame assembly mechanism (40) opens under the movement of the iron groove lever mechanism (31) and the six-link mechanism (36), and the umbrella frame assembly mechanism (40) completes the movement of opening the umbrella, thereby realizing the opening of the umbrella surface.

[0110] like Fig.13The middle pin hole (171.1) of the first scissor-fork unit shear rod 1 of the scissor-fork type linkage mechanism (17) and the middle pin hole (172.1) of the shear rod 2 are hinged through the middle hinge pin 5 (195). The first scissor-fork unit shear rod 1 (171) is divided into a shear rod front section (171.3) and a shear rod rear section (171.4) by the middle pin hole (171.1). The first scissor-fork unit shear rod 2 (172) of the scissor-fork type linkage mechanism (17) is also divided into a shear rod front section (172.3) and a shear rod rear section (172.4). The scissor-fork type lever mechanism (15) pries a joint mechanism (532) composed of a group of connecting rods. The connecting rod 1 (510) and the connecting rod 2 (511) form a joint 1 (512), and the connecting rod A (520) and the connecting rod B (521) form a joint 2 (522). Joint 1 (512) and joint 2 (522) form a joint mechanism (532). Link 1 (510) corresponds to the front section (171.3) of shear rod 1, link 2 (511) corresponds to the rear section (172.4) of shear rod 2, link A (520) corresponds to the front section (172.3) of shear rod 2, and link B (521) corresponds to the rear section (171.4) of shear rod 1. The front pin hole (171.0) of shear rod 1 is hinged to the pin hole 1 (510.1) of connecting rod 1; the rear pin hole (172.2) of shear rod 2 is hinged to the pin hole 2 (511.2) of connecting rod 2; the pin hole 2 (510.2) of connecting rod 1, the pin hole 1 (511.1) of connecting rod 2 and the bottom pin hole (151.2) of the left shear rod are hinged; the front pin hole (172.0) of shear rod 2 is hinged to the pin hole 1 (520.1) of connecting rod A; the rear pin hole (171.2) of shear rod 1 is hinged to the pin hole 2 (521.2) of connecting rod B; the pin hole 2 (520.2) of connecting rod A, the pin hole 1 (521.1) of connecting rod B and the bottom pin hole (152.2) of the right shear rod are hinged. The left shear rod (151) and the right shear rod (152) are hinged through their respective middle pin holes to form a scissor-fork type lever mechanism (15). The left shear rod (151) is hinged to the joint 1 (512) through the left shear rod bottom pin hole (151.2), and the right shear rod (152) is hinged to the joint 2 (522) through the right shear rod bottom pin hole (152.2). The power arm of the scissor-fork type lever mechanism (15) is closed inwardly, and its resistance arm pries the joint 1 (512) and the joint 2 (522) outwardly, and the two joints are straightened, driving the corresponding shear rod parts to straighten. In this way, a joint mechanism (532) composed of a pair of connecting rods is added to the scissor-fork type connecting rod mechanism (17), and the same driving purpose of the scissor-fork type connecting rod mechanism is achieved by driving the extension or folding of the joint mechanism (532). The variant structure of the scissor-fork type fulcrum movable lever mechanism (20) has the same function. The change in the distance D between the two joint points, i.e. the distance between the pin hole 1 (510.1) of the connecting rod 1 and the pin hole 2 (511.2) of the connecting rod 2, is equal to the linear displacement length of the scissor-type connecting rod mechanism (17) when it is stretched or folded.

[0111] Variant mechanism 2: Variant structure 2 of the scissor-type movable fulcrum lever mechanism

[0112] like Fig.14 The scissor-type fulcrum movable lever mechanism (20) is composed of a scissor-type connecting rod mechanism (17) and a spanner lever mechanism (80). The spanner lever hole (800.0) is hinged to the umbrella handle spanner lever pin hole (100.9) through the spanner lever pin (810), the spanner connection hole (800.1) is hinged to the pull rod upper hole (801.1), the pull rod lower hole (801.0) is hinged to the pull plate connection hole (802.3), and the middle hinge pin (195) passes through the pull plate centering groove (802.2) and slides along this groove to play a centering and directional role. The pull plate (802) is provided with a left pin track groove (802.0) and a right pin track groove (802.1).

[0113] When the pull plate (802) moves upward, the two track grooves move upward, causing the left hinge pin (811) and the right hinge pin (812) that are slidably connected to the two track grooves to expand outward along the tracks of the two grooves; when the pull plate (802) moves downward, the two track grooves move downward, causing the left hinge pin (811) and the right hinge pin (812) that are slidably connected to the two track grooves to move inward along the tracks of the two grooves. The connecting rod 1 pin hole 2 (510.2) and the connecting rod 2 pin hole 1 (511.1) are hinged by the left hinge pin (811), and the left hinge pin (811) passes through the left pin track groove (802.0) of the pull plate, and is driven by the motion track curve of the left pin track groove (802.0) of the pull plate; the connecting rod A pin hole 2 (520.2) and the connecting rod B pin hole 1 (521.1) are hinged by the right hinge pin, and the right hinge pin (812) passes through the right pin track groove (802.1) of the pull plate, and is driven by the motion track curve of the right pin track groove (802.1) of the pull plate. The connecting rod 1 (510) and the connecting rod 2 (511) form a joint 1 (512), and the connecting rod A (520) and the connecting rod B (521) form a joint 2 (522). The joint 1 (512) and the joint 2 (522) form a joint mechanism (532). The middle pin hole (171.1) of the first scissor-fork unit shear rod 1 and the middle pin hole (172.1) of the shear rod 2 of the scissor-fork type linkage mechanism (17) are hinged through the middle hinge pin 5 (195), and the first scissor-fork unit shear rod 1 (171) is divided into a shear rod front section (171.3) and a shear rod rear section (171.4) by the middle pin hole (171.1), and the first scissor-fork unit shear rod 2 (172) of the scissor-fork type linkage mechanism (17) is also divided into a shear rod front section (172.3) and a shear rod rear section (172.4). The wrench linkage mechanism (80) pries a joint mechanism (532) composed of a group of connecting rods, wherein the connecting rod 1 (510) and the connecting rod 2 (511) form a joint 1 (512), and the connecting rod A (520) and the connecting rod B (521) form a joint (522). The connecting rod 1 (510) corresponds to the front section (171.3) of the shear rod 1, the connecting rod 2 (511) corresponds to the rear section (172.4) of the shear rod 2, the connecting rod A (520) corresponds to the front section (172.3) of the shear rod 2, and the connecting rod B (521) corresponds to the rear section (171.4) of the shear rod 1. The front pin hole (171.0) of shear rod 1 is hinged to the pin hole 1 (510.1) of connecting rod 1; the rear pin hole (172.2) of shear rod 2 is hinged to the pin hole 2 (511.2) of connecting rod 2; the pin hole 2 (510.2) of connecting rod 1 and the pin hole 1 (511.1) of connecting rod 2 are hinged through a left hinge pin (811), and the left hinge pin (811) passes through the left pin track groove (802.0) of the pull plate; the front pin hole (172.0) of shear rod 2 is hinged to the pin hole 1 (520.1) of connecting rod A; the rear pin hole (171.2) of shear rod 1 is hinged to the pin hole 2 (521.2) of connecting rod B; the pin hole 2 (520.2) of connecting rod A and the pin hole 1 (521.1) of connecting rod B are hinged through a right hinge pin, and the right hinge pin (812) passes through the right pin track groove (802.1) of the pull plate.When a person presses the wrench (800), the wrench (800) rotates around the wrench lever pin (810), driving the pull rod (801) to rise, and the pull rod (801) rises and drives the pull plate (802) to rise. The rising direction of the pull plate (802) is guided by the middle hinge pin (195) installed on the pull plate center groove (800.2), and the middle hinge pin acts as a fulcrum and moves with the extension of the scissor-type connecting rod mechanism (17). The pull plate (802) rises, and the left hinge pin (810) and the right hinge pin (811) move along the movement trajectory of the pull plate left pin track groove (802.0) and the pull plate right pin track groove (802.1) on the pull plate (802), expand to both sides, support the joint 1 (512) and the joint 2 (522), and change the distance D between the two joint points. The change in the distance D between the two joint points is converted into a linear displacement of the extension or folding of the scissor-type connecting rod mechanism.

[0114] Variation mechanism 3: Variation of impulse mechanism

[0115] like Fig.15 The multiplier spring (750) is installed in the middle rod (220), one end of which abuts against the adapter block (232) or the lower nest (280), and the other end of which abuts against the lower end of the power punch (700); an ejector pin groove (700.0) is provided on the upper part of the power punch; one end of the eccentric spring (720) abuts against the upper end of the power punch (700), and the other end of the eccentric spring (720) abuts against the small punch boss (710.0); the upper end of the small punch (710) abuts against the lower end of the punch block (730), and the ejector pin (710.2) of the small punch at the lower end is subjected to the action of the eccentric spring (720) and tilts against the upper end surface of the power punch (700); the punch block (730) is fixed on the latch pin A (740), and the latch pin A (740) passes through the middle rod latch pin groove (220.1) and is fixed on the middle nest (290).

[0116] When the parachute is closed, the component relay rod (231) of the long-distance thrust mechanism (23) pushes the lower nest (280) to move upward, and the distance between the lower nest (280) and the middle nest (290) changes from B to A, and the distance becomes smaller and smaller. The main spring (240) is compressed, and the multiplier spring (750) is compressed to store elastic force. The eccentric spring (720) is also compressed, and as the distance between the lower nest (280) and the middle nest (290) further decreases, the upper end of the eccentric spring (720) presses into the small punch correction column (710.1), the eccentric spring (720) is corrected, and the small punch (710) is moved vertically and no longer remains tilted. When the small punch (710) moves to the vertical state, the small punch ejector pin (710.2) falls into the power punch ejector pin groove (700.0), and the depth of the power punch ejector pin groove (700.0) is the impact stroke C. The compressed multiplier spring (750) quickly releases its elastic force, and the power punch (700) is ejected. The power punch (700) hits the small punch pin (710.2), and the small punch (710) is quickly hit and raised, and then hits the punch block (730). The punch block (730) is subjected to an upward impact force, which is transmitted to the latch A (740), and the middle nest (290) is lifted. With the help of the umbrella frame assembly mechanism (40) closing and rising movement, the impulse mechanism (25) creates a force in the same direction of movement as the umbrella frame assembly mechanism (40), increasing the power of closing the umbrella and accelerating the compression of the main spring (240).

[0117] When the umbrella is opened, the main spring (240) of the umbrella frame assembly mechanism (40) releases its elastic force, the long-distance thrust mechanism (23) moves downward, the distance between the middle nest (290) and the lower nest (280) changes from A to B, the distance becomes larger and larger, the compressed multiplier spring (750) is gradually released, the eccentric spring (720) also gradually releases its elastic force, and pushes the force punch (700) downward. The multiplier spring (750) moves further downward in the middle rod as the long-distance thrust mechanism (23) moves downward, and the power punch (700) also moves downward in the middle rod. The eccentric spring (720) releases its elastic force and pushes the small punch ejector pin (710.2) out of the power punch ejector pin groove (700.0) during the downward movement. The eccentric spring (720) whose elastic force is released is separated from the upper part of the small punch correction column (710.1), and the eccentric structure of the eccentric spring (720) causes the small punch ejector pin to press against the upper end surface of the power punch (700).

[0118] The technical features of the above embodiments can be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments and variant mechanisms are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification. Although the presented illustrations are in the form of straight-pole umbrellas, the same applies to the structure, principle, and concept of folding umbrellas.

[0119] The above embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for those of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
