Specific embodiments

[0027] The following elaborates on the preferred embodiments of the present invention in conjunction with the attached drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art. It should be noted here that the description of these embodiments is used to help understand the present invention, but does not constitute a limitation to the present invention. In addition, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0028] Referring to Figure 1-7 as shown, in some embodiments, the collapsible sunshade of the present invention has a deployed state and a retracted state, and includes a vertical rod assembly, an umbrella frame structure, a flexible member 5, and an operating assembly.

[0029] The vertical rod assembly includes a fixed rod 1 and a movable rod 2 that can be arranged to move up and down relative to the fixed rod 1. Both the fixed rod 1 and the movable rod 2 extend in the up and down direction. Specifically, in one embodiment, the movable rod 2 is slidably inserted into the fixed rod 1 and can extend and shorten relative to the fixed rod 1.

[0030] The umbrella frame structure is arranged between the fixed rod 1 and the movable rod 2 and can be opened and folded relative to the fixed rod 1. Specifically, in one embodiment, the umbrella frame structure includes a canopy rod 3 and a strut 4. One end of the canopy rod 3 is rotatably connected to the upper end of the movable rod 2, one end of the strut 4 is rotatably connected to the middle of the canopy rod 3, and the other end of the strut 4 is rotatably connected to the fixed rod 1. As Figure 7 shown, in this embodiment, the number of canopy rods 3 is 6, and the number of struts 4 corresponds to that of the canopy rods, which is also 6. In other embodiments, the canopy rods 3 and the struts 4 can also be set to other numbers.

[0031] The flexible member 5 is wound around the fixed rod 1 and can rotate relative to the fixed rod 1. At least a part of the flexible member 1 is fixedly connected to the movable rod 2. In one embodiment, the flexible member 1 is a flexible rope, and in other embodiments, it can also be a flexible object such as a chain. A fixed pulley is provided on the fixed rod 1. The fixed pulley includes an upper fixed pulley 11 fixedly provided on the upper part of the fixed rod 1 and a lower fixed pulley 12 fixedly provided on the lower part of the fixed rod 2. The flexible member 5 is annularly wound around the fixed rod 2 through the upper fixed pulley 22 and the lower fixed pulley 23. In one embodiment, the upper fixed pulley 11 and the lower fixed pulley 12 are specifically cylindrical pins. The flexible member 5 is arranged inside the fixed rod 1. In one embodiment, a guiding member 13 can also be arranged inside the fixed rod 1 to separate the annularly wound flexible member 5 from the middle to prevent the flexible member 5 from getting entangled when rotating relative to the fixed rod 1. In one embodiment, a clamping ring 6 is fixedly provided on the flexible member 5, and the lower end of the movable rod 2 is fixedly connected to the flexible member 5 through the cooperation of a stud 7 and the clamping ring 6.

[0032] The operating assembly is used to convert the collapsible umbrella between the open state and the folded state. In one embodiment, the operating assembly includes a sliding member and a handle 9. The two end portions of the flexible member 5 are respectively fixedly connected to the sliding member. Specifically, the two ends of the flexible member 5 can be fixedly connected to the sliding member through the stud 7. The sliding member includes a sliding member body 81 and an abutting member 82 fixedly connected to the sliding member body 81. The handle 9 includes a handle body 91 and a fixing member 92 fixedly connected to the handle body 91. The handle body 91 is for the user to operate. The fixing member 92 is rotatably connected to the sliding member through a rotating shaft 10 extending in the left-right direction. A chute 14 extending in the up-down direction is formed on the fixed rod 1. The sliding member body 81 is clamped in the chute 14, so that the sliding member can slide up and down relative to the fixed rod 1. The abutting member 82 is located outside the fixed rod 1, and the abutting member 82 can abut and cooperate with or disengage from the fixed rod 1. Specifically, a beveled protrusion 821 is provided on one of the fixing member 92 and the abutting member 82, and a cooperating portion 921 cooperating with the beveled protrusion 821 is provided on the other, as Figure 1-4As shown, in one embodiment, an abutting member 82 is provided with an annular concave surface 822 on the left side close to the fixed rod 1, which is matched with the outer shape of the annular fixed rod 1. On the right side of the abutting member 82 close to the fixing member 1, there are provided an inclined surface protrusion 821 and a limiting member 823. The inclined surface protrusion 821 protrudes outward in a spiral shape to the right. On the left side of the fixing member 92 close to the abutting member 82, there is provided a matching portion 921 that cooperates with the inclined surface protrusion 821. The limiting member 823 protrudes toward the right and is used to limit the rotation of the handle 9 relative to the abutting member 82. Specifically, two limiting members 823 are provided. The collapsible sunshade has a locked state and an unlocked state. As Figure 3-4 shown, when in the locked state, the handle body 91 extends in the up-and-down direction. The matching portion 921 of the fixing member 92 is in interference fit with the inclined surface protrusion 821 of the abutting member 82, so that the annular concave surface 822 of the abutting member 82 closely fits on the fixed rod 1. The fixing member 92 abuts against one of the limiting members 823, preventing the user from further rotating the fixing member 92 clockwise relative to the abutting member 82. At this time, due to the frictional force between the abutting member 82 and the fixed rod 1, the sliding member and the handle 9 cannot slide relative to the fixed rod 1. When in the unlocked state, the matching portion 921 of the fixing member 92 rotates away from the inclined surface protrusion 821 of the abutting member 82, and the annular concave surface 822 of the abutting member 82 is separated from the fixed rod 1. The fixing member 92 abuts against the other limiting member 823, preventing the user from further rotating the fixing member 92 counterclockwise relative to the abutting member 82. At this time, the sliding member can slide relative to the fixed rod 1. When switching from the locked state to the unlocked state, the user only needs to rotate the handle 9 counterclockwise. When switching from the unlocked state to the locked state, the user only needs to rotate the handle 9 clockwise. Of course, in other embodiments, it can also be set that when switching from the locked state to the unlocked state, the user only needs to rotate the handle 9 clockwise, and when switching from the unlocked state to the locked state, the user only needs to rotate the handle 9 counterclockwise.

[0033] As Figure 7 shown, when in the open state, at this time the handle 9 is located relatively above the fixed rod 1, and the connection point of the flexible member 5 and the movable rod 2 is located relatively below the fixed rod 1, causing the movable rod 2 to shorten relative to the fixed rod 1, and the umbrella frame structure to move relatively away from the fixed rod 1, that is, to open relative to the fixed rod 1. As Figure 6 shown, when in the retracted state, at this time the handle 9 is located relatively below the fixed rod 1, and the connection point of the flexible member 5 and the movable rod 2 is located relatively above the fixed rod 1, causing the movable rod 2 to elongate relative to the fixed rod 1, and the umbrella frame structure to move relatively closer to the fixed rod 1, that is, to retract relative to the fixed rod 1. When switching between the open state and the retracted state, the handle 9 drives the flexible member 5 to rotate relative to the fixed rod 1, and then drives the movable rod 2 to move up and down relative to the fixed rod 1.

[0034] The following describes the usage method and principle of the collapsible sunshade of the present invention:

[0035] As shown Figure 6 , at this time, the collapsible sunshade is in the retracted state and in the locked state. The handle 9 is located below the chute 14 of the fixed rod 1, and the handle 9 extends in the up and down direction. Due to the interference fit between the mating portion 921 of the fixing member 92 and the inclined surface protrusion 821 of the abutting member 82, the annular concave surface 822 of the abutting member 82 fits against the outer wall of the fixed rod 1, causing the sliding member to be unable to slide relative to the fixed rod 1. The user rotates the handle 9 counterclockwise, that is, the handle 9 rotates 90 degrees relative to the abutting member 82 around the rotation axis 10 until the limiting member 823 of the abutting member 82 prevents the mating portion 921 from further rotating, and the mating portion 921 disengages from the inclined surface protrusion 821 of the abutting member 82, causing the annular concave surface 822 of the abutting member 82 to disengage from the outer wall of the fixed rod 1. At this time, the handle 9 extends in the horizontal direction. Then, the handle 9 is operated to slide upward relative to the fixed rod 1, driving the movable rod 2 to slide downward relative to the fixed rod 1, and the umbrella surface rod 3 rotates upward away from the fixed rod 1 around its pivot point with the movable rod 2. The support rod 4 rotates downward around its pivot point with the fixed rod 1 under the drive of the umbrella surface rod 3, and the umbrella frame structure opens relative to the fixed rod 1. Then, the handle 9 is operated to rotate 90 degrees clockwise relative to the abutting member 82 around the rotation axis 10 until the limiting member 823 of the abutting member 82 prevents the mating portion 921 from further rotating, and the mating portion 921 is in interference fit with the inclined surface protrusion of the abutting member 82, causing the annular concave surface 822 of the abutting member 82 to closely fit against the outer wall of the fixed rod 1. At this time, the handle 9 extends in the vertical direction, forming a collapsible sunshade as shown Figure 7 in the open state and in the locked state

[0036] In the description of the present invention, the directions such as "front", "rear", "left", "right", "up", and "down" involved are all defined with reference to the directions observed by the user when using the sunshade of the present invention, that is, as shown Figure 3 , the left side direction in the figure is "left", the right side direction in the figure is "right", the upper side direction in the figure is "up", the lower side direction in the figure is "down", and the directions perpendicular to the viewing angle in the figure are "front" and "rear". The definition of the above directions is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation to the present invention
