[0022] Please refer to Figures 1 to 7 , the electric umbrella stand of the embodiment of the present utility model includes a handle 1, a mounting bracket 2, a rotating screw 3, a motor 4, a sleeve rod 5, and a rotating screw sleeve 6. The mounting bracket 2 is fixedly arranged in the handle 1. The mounting bracket 2 is provided with a first fitting groove 21 and a second fitting groove 22. The first fitting groove 21 is communicated with the second fitting groove 22 through a through hole. The motor 4 is fixedly arranged in the first fitting groove 21. The output shaft of the motor 4 passes through the through hole and is arranged in the second fitting groove 22. The sleeve rod 5 is fixedly arranged in the second fitting groove 22. The rotating screw 3 is arranged in the sleeve rod 5. One end of the rotating screw 3 is provided with a third fitting groove. The output end of the motor 4 is pin-locked with the rotating screw 3. The rotating screw sleeve 6 is slidably arranged in the sleeve rod 5. When the rotating screw 3 rotates, it drives the rotating screw sleeve 6 to slide up and down.

[0023] In the above embodiment, the mounting bracket 2 is fixed inside the handle 1, which is provided with a first fitting groove 21 and a second fitting groove 22 that communicate with each other, and a through hole penetrating both of them. It provides an accurate positioning and limiting environment for the motor 4 and the rotating screw 3. The motor 4 is fixed in the first fitting groove 21, and its output passes through the through hole and extends into the second fitting groove 22 to ensure the linearity and stability of power transmission. The first fitting groove 21 is used to limit the motor 4 so that the motor 4 does not displace during operation. The sleeve rod 5 is fixedly installed in the second fitting groove 22. As a carrier of the rotating screw 3, it provides a stable space required for the rotation of the rotating screw 3. The rotating screw 3 is built into the sleeve rod 5, and a third fitting groove opened at one end thereof is tightly locked with the output end of the motor 4 by a pin, realizing a rigid connection between the motor 4 and the rotating screw 3. This connection method not only ensures the directness of power transmission but also avoids relative displacement between the two during use, effectively preventing loosening or jamming after long-term use. The rotating screw sleeve 6 is slidably arranged on the periphery of the sleeve rod 5. Its design enables the rotating screw 3 to drive the rotating screw sleeve 6 to slide up and down along the sleeve rod 5 through a threaded structure when rotating. This sliding mechanism is the opening and closing action of the umbrella surface, and its smoothness depends on the precise cooperation between the rotating screw 3 and the rotating screw sleeve 6 and the stable power output of the motor 4. In summary, the electric umbrella bracket constructs a stable and efficient transmission system through the limitation of the motor 4 and the rotating screw 3 by the mounting bracket 2 and the rigid connection between the motor 4 and the rotating screw 3 through a pin, ensuring the long-term stable operation of the automatic opening and closing function of the umbrella surface.

[0024] Please refer to Figures 1 to 7 , in another embodiment, a limiting post 221 is provided on the side wall of the second fitting groove 22, and a sliding groove 51 is opened on the side wall of the sleeve rod 5, and the sliding groove 51 is adapted to the limiting post 221.

[0025] In the above embodiment, limiting posts 221 are provided on the side wall of the second fitting groove 22. The main function of these limiting posts 221 is to limit the position of the sleeve rod 5 in the groove and prevent it from rotating or shifting left and right. Correspondingly, sliding grooves 51 that are closely adapted to the limiting posts 221 are opened on the side wall of the sleeve rod 5. The design of these grooves enables the side wall of the sleeve rod 5 to be firmly clamped by the limiting posts 221 after installation, thereby limiting the freedom of the sleeve rod 5 in the second fitting groove 22.

[0026] Please refer to Figures 1 to 7, in another embodiment, a first rotating thread 31 is provided on the outer side of the rotating screw 3. The rotating screw sleeve 6 includes a sliding cylinder 61, a sliding plate 62, and a rotating cylinder 63. The rotating cylinder 63 is disposed inside the rotating screw sleeve 6. The outer wall of the rotating cylinder 63 is connected to the inner wall of the sliding cylinder 61 through the sliding plate 62. A second rotating thread 631 is provided on the inner wall of the rotating cylinder 63. The sliding cylinder 61 is slidably disposed on the sleeve rod 5, the sliding plate 62 is slidably disposed in the sliding groove 51, and the rotating cylinder 63 is sleeved on the rotating screw 3 and is in threaded engagement.

[0027] In the above embodiment, the rotating cylinder 63 is located inside the rotating screw sleeve 6. Its outer wall is connected to the inner wall of the sliding cylinder 61 through the sliding plate 62, forming a structure that can slide relative to each other within a certain range. The inner wall of the rotating cylinder 63 is provided with a second rotating thread 631, enabling it to closely cooperate with the rotating screw 3 and transmit power through the rotation and engagement of the threads. At the same time, as the outer frame, the sliding cylinder 61 not only supports the entire structure of the rotating screw sleeve 6 but also is connected to the sleeve rod 5 through its own sliding setting, allowing the rotating screw sleeve 6 to move axially along the sleeve rod 5, thereby driving the opening and closing of the umbrella surface. The sliding plate 62 connects the rotating cylinder 63 and the sliding cylinder 61. Its sliding in the sliding groove 51 ensures the stability of the rotating cylinder 63 during rotation and also limits the offset of the rotating cylinder 63 in the horizontal direction, ensuring the accuracy of the transmission. Finally, the rotating cylinder 63 is closely sleeved and in threaded engagement with the first rotating thread 31 of the rotating screw 3 through the second rotating thread 631 inside it. This design enables the rotating screw sleeve 6 to rotate and move axially along the screw when the motor 4 drives the rotating screw 3 to rotate, thereby driving the sliding of the sliding cylinder 61 and causing the umbrella ribs on the sliding cylinder 61 to move, realizing the smooth opening and closing action of the umbrella surface.

[0028] Please refer to Figures 1 to 7 , in another embodiment, the handle 1 and the mounting bracket 2 are locked by a pin.

[0029] In the above embodiment, specifically, both are designed with precisely corresponding hole positions. When the mounting bracket 2 is placed inside the handle 1 and accurately positioned, the pin is inserted into these hole positions. The diameter of the pin is slightly smaller than the hole diameter but is sufficient to provide enough friction after insertion to prevent relative movement between the handle 1 and the mounting bracket 2. In this way, the pin physically locks the positions of the two, ensuring that the mounting bracket 2 is firmly fixed inside the handle 1 and providing a solid foundation support for the entire electric umbrella bracket.

[0030] Please refer to Figures 1 to 7 , in another embodiment, the sleeve rod 5 is provided with a limiting groove 52, and the side wall of the second fitting groove 22 is provided with a limiting synaptic knob 222 that matches the limiting groove 52.

[0031] In the above embodiment, when the sleeve rod 5 is installed in the second fitting groove 22, the limiting groove 52 and the limiting synaptic body 222 are engaged with each other, restricting the freedom of movement of the sleeve rod 5 in the horizontal direction and preventing unnecessary offset or rotation. This design ensures the stability of the sleeve rod 5 in the vertical direction and provides a basis for the precise operation of the transmission system. The tight fit between the limiting groove 52 and the limiting synaptic body 222 realizes the stable positioning of the sleeve rod 5 in the mounting bracket 2 through physical locking.

[0032] Please refer to Figures 1 to 7 , in another embodiment, a sealing ring is further sleeved on the motor 4.

[0033] In the above embodiment, the structural principle of the sealing ring sleeved outside the motor 4 is to form a physical barrier by closely fitting the gap between the outer shell of the motor 4 and the installation environment. The sealing ring is made of an elastic material and has good sealing performance and corrosion resistance. It can effectively prevent external impurities such as liquid and dust from entering the interior of the motor 4 and protect the motor 4 from damage. At the same time, the sealing ring can also buffer the vibration during the operation of the motor 4 to a certain extent, reduce noise transmission, and improve the overall operation stability.

[0034] The above are only the preferred embodiments of the present invention and do not impose any form of limitation on the present invention. Although the present invention has been disclosed above with preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some changes or modifications to equivalent embodiments by using the disclosed technical content within the scope of the technical solution of the present invention. However, as long as it does not depart from the content of the technical solution of the present invention, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention still fall within the scope of the technical solution of the present invention.
