Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0043] The purpose of the present invention is to provide an upper umbrella disk and an electric sunshade umbrella to solve the problems existing in the above-mentioned prior art, integrate the drive motor into the upper umbrella disk, simplify the structure, and enhance the strength of the electric sunshade umbrella.

[0044] To make the above objects, features, and advantages of the present utility model more obvious and understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0045] Embodiment 1

[0046] As Figures 1 - 10 shown, this embodiment provides an upper umbrella disk 100, which includes an umbrella disk main body and a rope driving device. An installation cavity is provided inside the umbrella disk main body, and the rope driving device is installed in the installation cavity. The output shaft of the rope driving device is connected to a winding shaft 5. When the rope driving device is started, the rope driving device is used to drive the winding shaft 5 to rotate. One end of an electric rope is connected to the winding shaft 5. Specifically, a rope fixing hole is provided on the winding shaft 5 to fix one end of the electric rope, and the electric rope will be partially wound around the winding shaft 5. The other end of the electric rope is used to connect to the lower umbrella disk 200. A rope perforation is provided on the umbrella disk main body, and the other end of the electric rope (i.e., the end away from the winding shaft 5) passes through the rope perforation. The advantage of this is that the electric rope is arranged outside the upper umbrella disk 100 or the umbrella rod 300, and does not occupy the internal space of the upper umbrella disk 100 and the umbrella rod 300, so that the internal space of the upper umbrella disk 100 and the umbrella rod 300 can be completely used for the power line to pass through. In addition, the rope driving device is electrically connected to the control device, and the control device is used to control the operation of the rope driving device. The control device can be arranged inside the umbrella disk main body, and of course, it can also be arranged at other positions of the entire umbrella body.

[0047] During actual use, the forward and reverse rotation of the rope driving device is controlled by the control device to realize the winding and unwinding of the electric rope. As the electric rope is wound and unwound, the other end of the electric rope will drive the lower umbrella disk 200 to move up and down along the umbrella rod 300, so as to achieve the technical effects of opening or closing the umbrella. In this embodiment, the rope driving device is integrated into the upper umbrella disk 100, which can simplify the overall structure, reduce the manufacturing cost, and improve the strength of the umbrella rod 300 part in the electric sunshade umbrella.

[0048] It includes an umbrella disk seat body 1, an umbrella disk cover group, a rope driving device, and a control device. The umbrella disk seat body 1 and the umbrella disk cover group are fixedly connected. The umbrella disk cover group is located at the upper end of the umbrella disk seat body 1. The lower end of the umbrella disk seat body 1 is used to connect to the umbrella rod 300. An installation cavity is provided inside the umbrella disk seat body 1 and the umbrella disk cover group.

[0049] In this embodiment, the drawstring driving device includes a driving motor 4 and a self-locking transmission mechanism 12. The output shaft of the driving motor 4 is connected to the input shaft of the self-locking transmission mechanism 12, and the output shaft of the self-locking transmission mechanism 12 is in transmission connection with the winding shaft 5. Specifically, they can be connected through a coupling. It is also possible to provide a groove matching the output shaft of the self-locking transmission mechanism 12 at one end of the winding shaft 5, and the output shaft of the self-locking transmission mechanism 12 can be directly inserted into this groove or connected by a key connection method.

[0050] The self-locking transmission mechanism 12 uses an existing reducer with a self-locking function, such as an existing worm and worm gear reducer. Those skilled in the art can also replace the self-locking transmission mechanism 12 with other parts or components that can be in transmission connection, as long as the power of the output shaft of the driving motor 4 can be transmitted to the winding shaft 5 and drive it to rotate.

[0051] In this embodiment, as Figure 10 shown, the umbrella disk main body further includes a support and fixing member 13. The support and fixing member 13 is a rectangular shell structure, and connection holes are provided at its four corners. Four threaded holes are also provided on the corresponding side surface of the self-locking transmission mechanism 12. The support and fixing member 13 is installed on one side of the self-locking transmission mechanism 12 through screws. A limiting hole 1301 is provided on the support and fixing member 13, and the end of the winding shaft 5 far from the self-locking transmission mechanism 12 is rotatably connected in the limiting hole 1301. The purpose of this setting is to ensure that the winding shaft 5 does not shake violently during rotation, thereby ensuring the stability of the equipment operation.

[0052] In this embodiment, the umbrella disk main body includes an umbrella disk seat body 1 and an umbrella disk cover group. The umbrella disk seat body 1 and the umbrella disk cover group are fixedly connected. Specifically, they can be an integral structure, or a split structure and later fixed through fixing methods such as screws. The umbrella disk cover group is located at the upper end of the umbrella disk seat body 1, and the lower end of the umbrella disk seat body 1 is used to connect with the umbrella rod 300. The installation cavity described above is provided inside the umbrella disk seat body 1 and the umbrella disk cover group.

[0053] In this embodiment, as Figure 5 shown, a plurality of small fan-shaped umbrella disk outer convex shells 101 are provided at intervals in the circumferential direction of the umbrella disk seat body 1. The space between two adjacent umbrella disk outer convex shells 101 is an umbrella rib installation gap 103, and each umbrella rib installation gap 103 is used to rotatably connect a first umbrella rib 400. It can be seen from the figure that a coil slot 102 is provided on both sides of each umbrella disk outer convex shell 101, and an umbrella rib coil is installed on all the coil slots 102 together. The umbrella rib coil is an iron ring, that is, after a circular umbrella rib coil passes through the corresponding through holes on each first umbrella rib 400 in sequence, the first umbrella rib 400 and the umbrella rib coil can rotate relative to each other, and then the umbrella rib coil can be placed at each coil slot 102.

[0054] The center of the umbrella base body 1 is provided with a motor receiving cavity 104, and the lower end of the drive motor 4 is inserted into the motor receiving cavity 104 to fix the drive motor 4.

[0055] In this embodiment, the umbrella disc cover assembly includes a first umbrella disc cover 2 and a second umbrella disc cover 3. The first umbrella disc cover 2 is closer to the umbrella disc base body 1 than the second umbrella disc cover 3, that is, the first umbrella disc is located between the second umbrella disc and the umbrella disc base body 1.

[0056] The specific structure of the first umbrella cover 2 is as follows: Figure 6 As shown, the first umbrella cover 2 is a circular disc-shaped structure. The first umbrella cover 2 is provided with a plurality of umbrella cover wire holes 201 at intervals in the circumferential direction. The umbrella cover wire holes 201 are used for the wires inside the umbrella rod 300 or umbrella ribs to pass through.

[0057] The specific structure of the second umbrella cover 3 is as follows: Figure 7 As shown, the second umbrella cover 3 is a disc structure, and the second umbrella cover 3 is provided with a motor through hole 301 and a mounting through hole 303, so that the upper end of the drive motor 4 can pass through the motor through hole 301 upwards.

[0058] One detail needs to be explained here, from Figure 5 As can be seen, the umbrella tray base body 1 has eight protruding umbrella tray housings 101, each with a connecting cylinder at its center and a connecting threaded hole at its upper end. Correspondingly, as... Figure 6 As shown, the first umbrella cover 2 also has eight connecting holes evenly distributed along its circumference, and these connecting holes on the first umbrella cover 2 are staggered with the umbrella cover wire holes 201, but correspond one-to-one with the eight threaded connecting holes on the umbrella base body 1. Further, it is easy to see from the figure that the eight connecting holes on the first umbrella cover 2 are not the same size, according to... Figure 6 To explain the direction, the connecting holes on the first umbrella cover 2 are divided into two groups, the first group being... Figure 6 The first group of holes has holes in the directions of top, bottom, left, and right; the second group has holes in the directions of top left, bottom left, top right, and bottom right. The diameter of the holes in the first group is larger than that of the holes in the second group. Similarly, the umbrella plate base body 1 is also divided into two groups of holes along this direction. For example... Figure 7The second umbrella disk cover 3 shown has four connecting holes, namely the holes in the directly upward, directly downward, directly leftward, and directly rightward directions, that is, corresponding to the positions of the first group of holes of the first umbrella disk cover 2 and the umbrella disk seat body 1. During the actual installation process, it is necessary to first connect the first umbrella disk cover 2 and the umbrella disk seat body 1. At this time, the second group of holes is used. By sequentially connecting the second group of holes on the first umbrella disk cover 2 and the umbrella disk seat body 1 with screws, the fixation of the two can be achieved. At this time, the wires inside the umbrella rod 300, the first umbrella rib 400, and the second umbrella rib 500 can be sorted out and sequentially passed through the corresponding umbrella cover wire passing holes 201. After the wires are all sorted out, then use four screws to sequentially pass through the four holes of the second umbrella disk cover 3, the four first group of holes in the first umbrella disk cover 2, and the four first group of holes in the umbrella disk seat body 1, and the fixation of the second umbrella disk cover 3, the first umbrella disk cover 2, and the umbrella disk seat body 1 can be achieved.

[0059] After the second umbrella disk cover 3, the first umbrella disk cover 2, and the umbrella disk seat body 1 are fixed, the control device can pass through the installation through hole 303 and be placed in the installation cavity.

[0060] In this embodiment, a wind monitoring device is installed at the upper end of the umbrella disk cover group. The wind monitoring device is used to monitor the wind force magnitude and feedback it to the control device to determine whether the driving motor 4 operates. The wind monitoring device includes a fan cover body 6. The fan cover body 6 is a frame structure and has a horizontally arranged circular plate at the center. A plurality of ventilation holes 601 are spaced in the circumferential direction of the fan cover body 6, and the external wind can pass through the ventilation holes 601 and enter the interior of the fan cover body 6. The upper end of the fan cover body 6 is connected with a fan cover 8 by means of a snap or a screw thread. A fan body 7 is installed inside the fan cover body 6. The fan body 7 includes a fan blade fixing seat 701. As can be seen from Figure 3 it, a connecting cylinder is provided at the center of the upper surface of the fan blade fixing seat 701. The fan blade fixing seat 701 is rotationally connected to the connecting cylinder of the fan cover body 6 through a rotary bearing 14. The inner ring of the rotary bearing 14 is fixedly connected to the outer wall of the connecting cylinder, and the outer ring of the rotary bearing 14 is connected to the central through hole of the fan blade fixing seat 701. A plurality of fan blades 702 are evenly distributed in the circumferential direction of the fan blade fixing seat 701. When the external wind passes through the ventilation holes 601 and enters the interior of the fan cover body 6, it will drive the fan blades 702 to rotate. The fan body 7 is electrically connected to the control device through a wind power conversion device. When the fan blades 702 rotate, relevant wind force information will be transmitted to the control device through the wind power conversion device. If the wind force is large, the control device will control the driving motor 4 to release part of the electric drawstring, so that the lower umbrella disk 200 moves downward due to its own weight, thereby closing the electric sunshade umbrella.

[0061] In this embodiment, a solar photovoltaic module 9 is installed at the upper end of the wind monitoring device. The solar photovoltaic module 9 is a prior art, including a solar photovoltaic panel and a storage battery. The solar photovoltaic panel is electrically connected to the storage battery. Further, devices such as a micro-inverter are also provided on the connecting wire between the solar photovoltaic panel and the storage battery. These are all existing mature technologies, so the specific details and working principles thereof will not be further elaborated herein. The storage battery in the solar photovoltaic module 9 is electrically connected to the control device to supply power to the control device. In addition, the storage battery can also be electrically connected to the drive motor 4 to provide electrical energy for it. As for the installation position of the storage battery, it can be installed in the installation cavity of the upper umbrella disk 100. Of course, those skilled in the art can also install it at positions such as the lower umbrella disk 200 or the umbrella rod 300. The position is not unique and can be selected according to the actual sizes of the storage battery and the electric sunshade umbrella.

[0062] In addition, if the solar photovoltaic module 9 is not provided, those skilled in the art can also install a battery compartment and use common dry batteries to supply power to the control device and the drive motor 4. Or directly connect to the mains power through a charging cable, which can also provide power for the electric sunshade umbrella.

[0063] In this embodiment, as Figure 9 shown, a transmission external tooth 703 is provided on the fan blade fixing seat 701, and a generator installation groove 602 is provided at the lower end of the fan cover body 6. The wind power conversion device includes a transmission gear 15 and a generator body 16. The transmission gear 15 is installed on the input shaft of the generator body 16, and the transmission gear 15 is located on the upper surface of the middle plate of the fan cover body 6. The transmission gear 15 meshes with the transmission external tooth 703. The generator body 16 is located on the lower surface of the fan cover body 6 and is installed in the generator installation groove 602. In addition, due to the large size of the generator body 16, a lower part accommodation cavity 302 for accommodating the lower part of the generator body 16 is further provided at the upper end of the second umbrella disk cover 3. The generator body 16 is electrically connected to the control device, and the control device includes a total control circuit board 10, which is an existing PCB board, on which a single-chip microcomputer (i.e., MCU) is installed. When the fan blade 702 drives the fan blade fixing seat 701 to rotate, the fan blade fixing seat 701 will cause the generator body 16 to generate current under the meshing action of the transmission external tooth 703 and the transmission gear 15. Subsequently, the current generated by the generator body 16 will be transmitted to the total control circuit board 10, and the single-chip microcomputer on the total control circuit board 10 will judge the magnitude of the current. If it exceeds a certain value (the specific data is set according to actual needs), the total control circuit board 10 will control the drive motor 4 to release part of the electric pull rope, thereby closing the electric sunshade umbrella to avoid the electric sunshade umbrella being blown down by strong wind.

[0064] Embodiment 2

[0065] As Figures 11 - 13As shown in the figure, this embodiment provides an upper umbrella disk 100. The technical features provided in this embodiment are basically the same as those disclosed in the first embodiment, except that the wind power conversion device is different.

[0066] In this embodiment, a shielding piece 18 is connected to the lower end of the fan blade fixing seat 701, specifically three are provided, and the three shielding pieces 18 are circumferentially distributed at the lower end of the fan blade fixing seat 701. The wind power conversion device includes a U-shaped photoelectric switch 17 (also called a slot-type opposed photoelectric switch). The U-shaped photoelectric switch 17 can be installed on the fan cover body 6 or other positions that can contact the shielding piece 18. When the shielding piece 18 rotates, it can pass through the U-shaped photoelectric switch 17, and the U-shaped photoelectric switch 17 is electrically connected to the control device.

[0067] When the fan blade 702 drives the fan blade fixing seat 701 to rotate, the fan blade fixing seat 701 drives the shielding piece to make a rotational motion. When the shielding piece 18 passes through the U-shaped photoelectric switch 17, it will block the optical path of the U-shaped photoelectric switch 17. The U-shaped photoelectric switch 17 will transmit a trigger signal to the main control circuit board 10. If it exceeds a certain value (specific data is set according to actual needs), the main control circuit board 10 will control the driving motor 4 to release part of the electric drawstring, thereby closing the electric sunshade umbrella and avoiding the electric sunshade umbrella being blown down or damaged by strong wind.

[0068] Embodiment Three

[0069] As Figures 14 - 16 shown in the figure, this embodiment provides an electric sunshade umbrella, including the upper umbrella disk 100 disclosed in Embodiment One and Embodiment Two.

However, generally, they are in a connected state. There are multiple first umbrella ribs 400 and second umbrella ribs 500, and the number of the first umbrella ribs 400 and the second umbrella ribs 500 is the same and their positions correspond one by one. Among them, one end of the first umbrella rib 400 is hinged at the umbrella rib installation gap 103 on the upper umbrella disc 100, one end of the second umbrella rib 500 is hinged near the middle of the first umbrella rib 400, and the other end of the second umbrella rib 500 is hinged on the peripheral groove of the lower umbrella disc 200. The umbrella cloth 600 is installed on each first umbrella rib 400, that is, the upper surfaces of each first umbrella rib 400 jointly support an umbrella cloth 600. The control switch 700 is installed on the umbrella rod 300, and the control switch 700 is electrically connected to the control device. The control switch 700 includes a motor start button. When the motor start button is pressed, the total control circuit board 10 will start the drive motor 4 to run.

[0071] In this embodiment, a lighting lamp can also be installed on the first umbrella rib 400. Correspondingly, the control device further includes a lamp control circuit board 11, and the control switch 700 further includes a lamp control button. The lighting lamp and the lamp control button are both electrically connected to the lamp control circuit board 11.

[0072] During actual use, the user only needs to press the lamp control button, and the control instruction is transmitted to the lamp control circuit board 11, and then the lamp control circuit board 11 controls the lighting lamp to turn on or off.

[0073] In this embodiment, an upper proximity switch and a lower proximity switch can be installed on the umbrella rod 300. The upper proximity switch is located above the lower proximity switch, and both the upper proximity switch and the lower proximity switch are electrically connected to the total control circuit board 10. A detection metal, such as an iron sheet, is installed on the lower umbrella disc 200. When the lower umbrella disc 200 moves to the position of the upper proximity switch or the lower proximity switch, the upper proximity switch or the lower proximity switch will detect the position signal of the lower umbrella disc 200 and transmit it to the total control circuit board 10. After the lower umbrella disc 200 moves to the expected position, the total control circuit board 10 controls the drive motor 4 to stop running.

[0074] In actual use, when the driving motor 4 rotates to drive the lower umbrella disk 200 to move to the upper proximity switch position, the upper proximity switch detects the position signal of the detected metal and transmits the signal to the total control circuit board 10. The total control circuit board 10 controls the driving motor 4 to stop rotating. At this time, the umbrella cloth 600 is in a fully opened state. When it is necessary to control the retraction of the umbrella cloth 600, the driving motor 4 rotates in the reverse direction. When the lower umbrella disk 200 moves to the position of the lower proximity switch, the lower proximity switch senses the position signal of the detected metal and transmits the position signal to the total control circuit board 10. The total control circuit board 10 controls the driving motor 4 to stop rotating. At this time, the umbrella cloth 600 is in a retracted state.

[0075] In addition, a limiting column can be installed at the upper end of the umbrella rod 300. When the lower umbrella disk 200 moves to the highest position (at this time the umbrella cloth 600 is opened), the lower umbrella disk 200 will abut against the limiting column, so as to play a role in limiting the lower umbrella disk 200 and prevent it from moving too much.

[0076] In the present utility model, specific examples are used to elaborate on the principle and implementation manner of the present utility model. The description of the above embodiments is only used to help understand the method and its core idea of the present utility model; at the same time, for those of ordinary skill in the art, according to the idea of the present utility model, there will be changes in the specific implementation manner and application scope. In summary, the content of this specification should not be construed as a limitation to the present utility model.
