[0098] The middle rod 12 includes a plurality of sleeves connected from the inside to the outside, and the plurality of sleeves can be pulled apart to form a long pole connected end to end. The umbrella 100 can be a two-fold umbrella, a three-fold umbrella, or a five-fold umbrella, etc., and the middle rod 12 correspondingly includes two sleeves, three sleeves, or five sleeves, etc. In this embodiment, the middle rod 12 includes three sleeves, which are an inner sleeve 121, a middle sleeve 122, and an outer sleeve 123 from the inside to the outside. The inner sleeve 121, the middle sleeve 122, and the outer sleeve 123 are telescopically connected in sequence. When the middle rod 12 is pulled apart to form a long pole, the shell 111, the inner sleeve 121, the middle sleeve 122, and the outer sleeve 123 are arranged in sequence. The upper nest 13 is arranged at one end of the outer sleeve 123 away from the umbrella head 11, and the lower nest 14 is slidably arranged on the outer sleeve 123. One end of the inner sleeve 121 extends into and is fixed in the shell 111 of the umbrella head 11.

[0099] The umbrella frame 31 includes a first rib 311, a second rib 312, a tension spring 313 and a third rib 314. One end of the first rib 311 is connected to the upper nest 13.

The umbrella is arranged on the umbrella frame 31.

[0100] In one embodiment, the umbrella pole structure 10 also includes an umbrella pole transmission assembly 15 and an umbrella rib transmission assembly 19, and the umbrella pole transmission assembly 15 and the umbrella rib transmission assembly 19 are used in conjunction with each other, so that when the button 1111 is pressed, the driving assembly 112 can open the umbrella 100 through the umbrella pole transmission assembly 15 and the umbrella rib transmission assembly 19; when the button 1111 is pressed again, the driving assembly 112 can fold the umbrella 100 through the umbrella pole transmission assembly 15 and the umbrella rib transmission assembly 19.

[0101] In one embodiment, the umbrella rod transmission assembly 15 is disposed in the middle rod 12 of the umbrella 100. When the umbrella rod transmission assembly 15 applies force to the middle rod 12, the multiple sleeves of the middle rod 12 can be pulled apart to form a long rod connected end to end, so that the umbrella rod of the umbrella 100 is extended, that is, the step of opening the umbrella 100 is completed; when the force applied by the umbrella rod transmission assembly 15 to the middle rod 12 is cancelled, under the action of the tension spring 313 (from the compressed state to the natural state), the multiple sleeves of the middle rod 12 can be connected from the inside to the outside, thereby completing the step of folding the umbrella 100.

[0102] In a specific embodiment, the umbrella rod transmission assembly 15 is located in the inner sleeve 121 and can apply force to the upper nest 13. The upper nest 13 is arranged at one end of the outer sleeve 123 away from the umbrella head 11, so that the umbrella rod transmission assembly 15 can indirectly apply force to the outer sleeve 123 through the upper nest 13.

[0103] In one embodiment, the umbrella rod transmission assembly 15 includes a first transmission tube 151, a second transmission tube 152 sleeved outside the first transmission tube 151, a rotating member 153 sandwiched between the first transmission tube 151 and the second transmission tube 152, a rotation-blocking member 154, an elastic member 155, and a first mounting member 157. The umbrella rod transmission assembly 15 may further include a reinforcing tube 156, which may be sleeved outside the second transmission tube 152. The second transmission tube 152 may be a rectangular spring, and the rectangular spring has an internal thread and an external thread. It should be noted that the rectangular spring is also called a mold spring, because the manufacturing material is a square wire (ordinary springs are round wire materials), and the cross-section of the square wire is rectangular, so it is called a rectangular spring. The first end 1511 of the first transmission tube 151 has an external thread 1512, and the second end 1513 has a support portion 1514. The size of the support portion 1514 is not less than the size of the rod body of the first transmission tube 151. The first transmission tube 151 is provided with a rotation-blocking groove 1515 along its axial direction. The rotation-blocking groove 1515 passes through the first end 1511, the second end 1513 and the support portion 1514. The second transmission tube 152 is connected to the output shaft (not shown) of the driving assembly 112, and the driving assembly 112 can drive the second transmission tube 152 to rotate relative to the umbrella head 11.

[0104] In another embodiment, Fig.39 The outer surface of the second transmission tube 152' has an external thread, and the inner wall has an internal thread, which can be made by extrusion molding or by ordinary machining. Specifically, the internal thread or external thread can be formed by extruding the inner wall or outer wall of a hollow round tube. The tube wall of the second transmission tube 152' is a solid structure, and the outer surface of the solid tube wall has an external thread, and the inner wall has an internal thread. The second transmission tube 152' can be called a threaded tube or a threaded round tube.

[0105] In one embodiment, the second transmission tube 152, the reinforcement tube 156, and the first mounting member 157 may be an integrally formed structure and serve together as the second transmission tube. In another embodiment, the second transmission tube 152, the reinforcement tube 156, and the first mounting member 157 may be independent components and assembled together.

[0106] The first mounting member 157 is generally a tubular structure, and the first mounting member 157 is provided with a through hole 1571, and a threaded portion 1572 is convexly provided on the outer surface, and a protrusion 1573 is provided at one end of the threaded portion 1572, and a groove 1574 is provided at the other end. The first mounting member 157 is also convexly provided with a stopper 1576, and the stopper 1576 is annularly arranged on the outer surface of the first mounting member 157, and the threaded portion 1572 can be spirally extended from the stopper 1576 on the outer surface of the first mounting member 157 to the top of the first mounting member 157. The second transmission tube 152 can be a rectangular spring, and one end of the second transmission tube 152 can be matched and connected with the threaded portion 1572 to install the second transmission tube 152 on the first mounting member 157. Specifically, after the rectangular spring of the second transmission tube 152 is installed on the first mounting member 157, the end of the rectangular spring can be stopped by the protrusion 1573; the inner surface of the reinforcing tube 156 is provided with a protrusion (not shown), which can be accommodated in the groove 1574, so as to connect the reinforcing tube 156 with the first mounting member 157. It can be understood that the protrusion can be formed by the tube wall of the reinforcing tube 156 being concave from the outside to the inside, and the outer surface of the reinforcing tube 156 corresponding to the protrusion is formed with a groove.

[0107] The first transmission tube 151, the second transmission tube 152, and the rotating member 153 cooperate with each other, so that the umbrella 100 can be extended to a greater distance and have a higher height. Specifically, when the umbrella 100 is opened, the second transmission tube 152 drives the rotating member 153 to rotate, and the rotating member 153 moves upward while rotating relative to the second transmission tube 152, and drives the first transmission tube 151 to further move upward on the basis of the rotating member 153, so that the umbrella 100 can rise higher and extend to a greater distance.

[0108] The rotating member 153 is generally tubular in structure and can also be referred to as a rotating tube. The aperture of the through hole 1531 of the rotating member 153 is larger than the diameter of the first transmission tube 151, so that the first transmission tube 151 can be rotatably mounted in the rotating member 153. An external thread 1532 is provided at one end of the rotating member 153. The external thread 1532 of the rotating member 153 engages with the internal thread of the second transmission tube 152, so that the second transmission tube 152 can rotate relative to the rotating member 153. An internal thread 1534 is convexly provided at one end of the rotating member 153 away from the first mounting member 157. The rotating member 153 is sleeved outside the first transmission tube 151, and the internal thread 1534 engages with the external thread 1512 of the first transmission tube 151. The internal thread 1534 is adjacent to the opening of the rotating member 153 and is spirally arranged on the inner surface of the rotating member 153. When the rotating member 153 is mounted on the first mounting member 157 , the initial end 1533 of the external thread 1532 of the rotating member 153 matches with the terminal end 1575 of the threaded portion 1572 of the first mounting member 157 .

[0109] The end of the external thread 1512 of the first transmission tube 151 is bent and extended to the anti-rotation groove 1515 to form a stopper 1516. The stopper 1516 can be arranged in contact with the groove wall of the anti-rotation groove 1515, or can be arranged at a distance from the groove wall of the anti-rotation groove 1515. The end 1535 of the internal thread 1534 of the rotating member 153 (i.e., the end close to the umbrella head 11) and the stopper 1516 of the first transmission tube 151 stop each other to prevent the first transmission tube 151 from completely extending out of the rotating member 153.

[0110] The first mounting member 157 is formed with a connecting portion 1577 at one end away from the upper nest 13, and the connecting portion 1577 is formed with a connecting hole 1578. The first mounting member 157 can be formed by extruding the inner wall or the outer wall of a hollow round tube. The driving assembly 112 includes a motor 1121, a motor tooth 1122 sleeved on the output shaft of the motor 1121, a speed gear 1123 meshed with the motor tooth 1122, and an output tooth 1124 meshed with the speed gear 1123. The shape of the connecting hole 1578 matches the shape of the connecting shaft 1125 of the output tooth 1124.

[0111] The reinforcing tube 156 is sleeved outside the second transmission tube 152, and the second transmission tube 152 and the reinforcing tube 156 can be sleeved outside the rotating member 153 and extend outside the rotating member 153. That is, the second transmission tube 152 and the reinforcing tube 156 are longer than the rotating member 153. The inner sleeve 121 can be sleeved outside the reinforcing tube 156, and the lengths of the inner sleeve 121, the second transmission tube 152 and the reinforcing tube 156 are substantially the same or the same.
