[0002] As an outdoor leisure tool, parasols are widely used in leisure places such as squares, beaches, parks and courtyards, providing people with a comfortable space to enjoy the cool. The structure of existing parasols is generally composed of an umbrella pole, an umbrella frame and an umbrella cloth. The umbrella frame is connected to the top of the umbrella pole. The umbrella pole mainly supports the umbrella frame. The umbrella cloth is connected to the umbrella frame. When the umbrella frame is opened, the umbrella cloth is also opened, so that the parasol is opened. The umbrella surface area required for outdoor parasols is relatively large. At present, the opening and closing of the parasol is mostly operated manually or by a motor-driven gear, worm gear or other mechanism to open and close the parasol.

[0003] In the above-mentioned prior art, the operation of manually operated parasols is time-consuming and laborious, and the parasols with motor-driven gears and worm gear mechanisms have high requirements for parts processing, relatively high costs, and expensive repair costs when the product is damaged. Therefore, it is necessary to design a parasol that can electric Opening and closing is convenient for operation, low cost and safer.

[0004] After investigation, the existing Chinese patent number is 201520724492.9 "A Solar Electric Sunshade Umbrella", which includes an umbrella body, which is composed of an umbrella pole, an umbrella rib connected to the umbrella handle, and an umbrella cover covered on the umbrella rib.

[0019] The present invention is further described in detail below with reference to the accompanying drawings.

[0020] like Figures 1 to 4 As shown, an electrically opened and closed parasol comprises an upper umbrella plate 2, a lower umbrella plate 3, a long umbrella rib 4, a short umbrella rib 5 and a middle rod 1, wherein the long umbrella rib 4 is rotatably hinged to the upper umbrella plate 2, one end of the short umbrella rib 5 is hinged to the lower umbrella plate 3, and the other end of the short umbrella rib 5 is hinged to the upper part of the long umbrella rib 4 to form an umbrella frame, and the middle rod 1 comprises an outer tube 12 and an inner tube 11, and the inner tube 11 can be slidably positioned and penetrated in the upper part of the outer tube 12, and the bottom of the inner tube 11 is hinged to the outer tube 12. A closed air chamber A is formed between the tubes 12, the upper umbrella plate 2 is fixedly mounted on the top position outside the inner tube 11, and the lower umbrella plate 3 is detachably mounted and fixed outside the outer tube 12. An electric air pump 6 is provided in the inner tube 11, which can inflate or exhaust the air chamber A and thereby drive the inner tube 11 to slide up and down. The upper umbrella plate 2 can slide up and down relative to the outer tube 12 and the lower umbrella plate 3 through the up and down sliding of the inner tube 11, thereby driving the long umbrella ribs 4 and the short umbrella ribs 5 to complete the opening and closing of the parasol.

[0021] The specific structure is as follows: a piston 9 is detachably provided at the bottom of the inner tube 11, a pipe plug 8 is detachably provided at the bottom of the outer tube 12, a through hole 93 for the air supply nozzle 61 to pass through is provided in the middle of the piston 9, connecting holes 91 are radially provided on the side of the piston 9, and threaded through holes are provided at corresponding positions of the inner tube 11. The piston 9 and the inner tube 12 are fixed by fixing bolts 71, the lower end of the piston 9 extends out of the inner tube 11, and a first sealing ring 92 is embedded in the outer edge of the lower end to tightly fit with the inner wall of the outer tube 12. A connecting through hole 81 is radially opened on the lower side surface of the pipe plug 8, and a threaded hole is opened at the corresponding position of the outer tube 12. The pipe plug 8 and the outer tube 11 are fixed by bolts 72. A second sealing ring 82 is embedded in the upper outer edge of the pipe plug 8 and tightly fits with the inner wall of the outer tube 11, so that a closed air chamber A is formed between the piston 9, the pipe plug 8 and the inner wall of the outer tube 12. When the umbrella frame is subjected to external force caused by wind, a pneumatic spring is formed inside it to buffer the external force; the electric air pump 6 is arranged at the upper end of the piston 9, and the bottom of the electric air pump 6 is provided with an air nozzle 61, which passes through the piston 9 and is connected with the air chamber A. The air chamber A can be inflated or exhausted by the electric air pump 6.

[0022] A power module for supplying power to the electric air pump 6 is provided at the top of the inner tube 11 and the upper end of the upper umbrella plate 2. The power module includes a battery 10 and a circuit board. The power module is electrically connected to the electric air pump 6 in the inner tube 11 through wiring. The battery 10 is a solar cell, and a solar panel is provided in the power module to charge the battery 10. The circuit board can adopt a wireless control circuit, and a wireless device can be used to operate the parasol. The wireless device includes but is not limited to a remote control, a Bluetooth mobile phone, and the like.

[0023] The specific operation is as follows:

[0024] The operating switch controls the electric air pump 6 to start forward rotation, filling air into the air chamber A. The air pressure in the air chamber A continues to rise. When the air pressure in the air chamber A exceeds the atmospheric pressure, the piston 9 is subjected to the upward pressure to push the inner tube 11 to slide upward. At this time, the upper umbrella plate 2 and the inner tube 11 move upward synchronously, driving the umbrella frame to fold and complete the folding of the umbrella; the operating switch controls the electric air pump 6 to start reverse rotation, extracting air from the air chamber A, causing the air pressure in the air chamber A to continue to drop. When the air pressure in the air chamber A is less than the atmospheric pressure, the piston 9 receives the downward pulling force to pull the inner tube 11 downward. At the same time, the upper umbrella plate 2 and the inner tube 11 move downward synchronously, driving the umbrella frame to open and complete the umbrella opening; when the umbrella is opened, the piston 9 and the pipe plug 8 fit together, and the air pressure in the air chamber A is close to vacuum, forcing the piston 9 and the pipe plug 8 to be firmly adsorbed together, thereby fixing the open state of the umbrella frame; after the umbrella frame is opened, when the long umbrella ribs 4 are subjected to external forces such as wind, there is a tendency to drive the upper umbrella plate 2 and the inner tube 11 to slide up and down. Since the gas in the air chamber A cannot flow when the electric air pump 6 is not started, a gas spring is formed to buffer the force of the inner tube 11 sliding up and down, thereby extending the product life.

[0025] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
