[0032] See also Figure 1-Figure 8 The embodiment of the utility model provides an outdoor parasol, including an umbrella body 1 and a driving mechanism. The umbrella body 1 includes a main column 101, a plurality of ribs 102 and an umbrella cloth 103 arranged on the ribs 102. A secondary column 104 is sleeved inside the main column 101 of the umbrella body 1; a plurality of pulleys 105 are arranged on the outside of the secondary column 104, and a guide groove 1011 adapted to the pulley 105 is arranged on the inside of the main column 101. The main column 101 and the secondary column 104 are slidably connected through the pulley 105 and the guide groove 1011; when the driving mechanism drives the secondary column 104 to move up and down in the main column 101, the ribs 102 are synchronously driven to open or fold.

[0033] This embodiment can enhance the wind resistance of the outdoor parasol and prevent it from being broken easily by setting two layers of columns, namely, the main column 101 and the auxiliary column 104. In addition, by setting the pulley 105 on the outside of the auxiliary column 104 and the guide groove 1011 on the inside of the main column 101, when the power unit 202 drives the auxiliary column 104 to move axially along the screw rod 201 and the main column 101 to open or close the umbrella rib 102, under the action of the guide groove 1011, the pulley 105 on the auxiliary column 104 slides on the guide groove 1011 of the main column 101, guiding the movement of the auxiliary column 104, so that the outdoor parasol can be opened or closed more smoothly.

[0034] Among them, Figure 1-Figure 4As shown, the driving mechanism includes a screw rod 201 and a power unit 202 for driving the screw rod 201 to rotate. The screw rod 201 is arranged in the secondary column 104 and the nut seat 203 of the screw rod 201 is fixedly connected to the secondary column 104. When the power unit 202 drives the screw rod 201 to rotate, the secondary column 104 moves axially along the screw rod 201 and the main column 101, and synchronously drives the umbrella ribs 102 to open or fold. In this embodiment, the power unit 202 drives the screw rod 201 to rotate, so that the nut seat 203 on the screw rod 201 can drive the secondary column 104 to move up and down in the main column 101, thereby opening or folding the outdoor parasol. Among them, the power unit 202 can be a DC servo motor, and the shaft end of the screw rod 201 can be connected to a linear transmission or a right-angle transmission through a joint, and the linear transmission or the right-angle transmission is then connected to a DC servo motor, thereby driving the screw rod 201 to rotate; wherein, the DC servo motor drives the screw rod 201 to rotate, which belongs to the existing conventional technology, and this application will not go into details here.

[0035] Specific examples include Figure 3 , Figure 5 and Figure 6 As shown, the main column 101 and / or the secondary column 104 are multi-layer hollow structures, that is, the main column 101 can be set as a multi-layer hollow structure, or the secondary column 104 can be set as a multi-layer hollow structure, or both the main column 101 and the secondary column 104 can be set as a multi-layer hollow structure, which can further enhance the wind resistance of the column and make the column composed of the main column 101 and the secondary column 104 not easily broken.

[0036] Among them, preferably Figure 3 , Figure 5 and Figure 6 As shown, the cross-sectional shape of the main column 101 and / or the auxiliary column 104 is a double-layer hollow polygon, which not only improves the wind resistance of the column, but also facilitates the installation of the auxiliary column 104 inside the main column 101 without hindering the movement of the auxiliary column 104. Among them, the cross-sectional shape of the main column 101 and / or the auxiliary column 104 can be preferably a double-layer octagonal shape for easy processing. Of course, the cross-sectional shape of the main column 101 and / or the auxiliary column 104 can also be set to other shapes, and the utility model is not limited here.

[0037] In one embodiment, the umbrella body 1 further includes a first umbrella plate 106 connected to the driving end of the umbrella rib 102 and a second umbrella plate 107 connected to the fixed end of the umbrella rib 102. One end of the secondary column 104 is connected to the nut seat 203, and the other end is fixedly connected to the first umbrella plate 106; the second umbrella plate 107 is fixedly connected to the middle and upper part of the main column 101. The first umbrella plate 106 and the second umbrella plate 107 are used to connect the umbrella ribs, so that the secondary column 104 can open or retract the umbrella ribs when moving up and down in the main column 101.

[0038] Specifically, the ribs 102 include a main rib 1021 and a secondary rib 1022, one end of the main rib 1021 is hinged to the first umbrella plate 106 through a first bearing 1023, one end of the secondary rib 1022 is hinged to the second umbrella plate 107 through a second bearing 1024, and the other end of the secondary rib 1022 is hinged to the middle of the main rib 1021 through a third bearing 1025. When the secondary column 104 moves upward, the secondary column 104 drives the first umbrella plate 106 to move upward. At this time, the angle between the main umbrella rib 1021 and the secondary umbrella rib 1022 gradually increases and tends to 180°, thereby folding the umbrella rib 102; and when the secondary column 104 moves downward, the secondary column 104 drives the first umbrella plate 106 to move downward. At this time, the distance between the first umbrella plate 106 and the second umbrella plate 107 becomes smaller, and the angle between the main umbrella rib 1021 and the secondary umbrella rib 1022 gradually decreases, thereby opening the umbrella rib.

[0039] In this embodiment, Figure 1 As shown, the first bearing 1023, the second bearing 1024 and the third bearing 1025 all adopt a double bearing structure. Since the center point of the double bearing structure is relatively uniform, the first bearing 1023, the second bearing 1024 and the third bearing 1025 will not be excessively worn during the long-term opening or folding process of the umbrella ribs, so that the positioning during the opening or folding process of the umbrella ribs 102 will be more accurate, and the opening or folding process will be smoother.

[0040] Existing outdoor parasols are now generally used in commercial shops, such as beach outdoor restaurants, commercial camping, etc., so outdoor parasols are also needed at night to achieve a certain atmosphere setting effect; therefore, some light strips can be set on the outdoor parasols to facilitate lighting or atmosphere setting when used at night. Therefore, a first groove 10221 for placing a first light strip can be set along the axial direction on the outside of the secondary umbrella rib 1022, which is used to place the light strip for lighting at night; further, a second groove 10222 for placing a second light strip can be set along the axial direction on the outside of the secondary umbrella rib 1022, wherein the first groove 10221 and the second groove 10222 are located on different side walls, wherein the first light strip is a lighting lamp, and the second light strip is an RGB atmosphere lamp, so that the outdoor parasol has both a sense of atmosphere and lighting when used at night. Preferably, the first groove 10221 and the second groove 10222 are set back to back, and the first groove 10221 is facing the ground when the outdoor parasol is used, so that the lighting lamp can achieve a better lighting effect.

[0041] Furthermore, Figure 7As shown, the main rib 1021 is also provided with a third groove 10211 for placing a third light strip, wherein the third light strip is a double spotlight to increase the lighting brightness. In a preferred embodiment of the utility model, by setting a lighting lamp in the first groove 10221 of the auxiliary rib 1022, setting an RGB atmosphere light in the second groove 10222 of the auxiliary rib 1022, and setting a double spotlight in the third groove 10211 of the main rib 1021, it can not only achieve a lighting effect, but also achieve a better lighting effect, which can play a role in setting the atmosphere. Of course, this is only one embodiment provided in this embodiment, and users can also place other light strips according to their preferences to achieve the lighting effect they want, and this embodiment is not limited here.

[0042] In this embodiment, different corresponding grooves for placing light strips are provided on the main ribs 1021 and the auxiliary ribs 1022, thereby facilitating the fixation of the light strips. Furthermore, since the wires of each light strip are also stored in the main ribs 1021 and the auxiliary ribs 1022, when the outdoor parasol needs to be folded up for storage, it is only necessary to fold the outdoor parasol, which is quite convenient.

[0043] Further, such as Figure 5 As shown, the outer side of the main column 101 is provided with a plurality of placement grooves 1012 for placing connecting wires, wherein the connecting wires of the first light strip, the second light strip, the third light strip, etc. extend through the placement grooves 1012 and into the base 3 to hide the connecting wires and prevent the connecting wires from being damaged by external forces when the outdoor parasol is in use. The placement grooves 1012 are provided with a detachable closing cover 1013 to facilitate maintenance. The control panel for controlling the auxiliary column 104 is provided on the outer side of the main column 101, and the connecting wires of the control panel are also extended through the placement grooves 1012 into the base 3 to connect with the controller circuit.

[0044] In addition, closing covers 1013 may also be provided at the first groove 1021 , the second groove 10222 , and the third groove 10211 , respectively, to facilitate replacement and maintenance of the light strip.

[0045] In a preferred embodiment, the outdoor parasol also includes a base 3, and the bottom of the main column 101 is fixedly connected to the base 3. The base 3 can be used to fix the outdoor parasol, and the base 3 can also increase the weight of the outdoor parasol base 3 to make the wind resistance better. The bottom of the base 3 is provided with a ground anchor bolt 401 for fixing the base 3 to the ground. In this embodiment, a DC servo motor, a controller for controlling the DC servo motor and the light strip, a transformer, etc. can be installed in the base 3. A door cover can also be provided on the base 3 to facilitate the maintenance of components such as electrodes, controllers and transformers.

[0046] In addition, a safety seat 4 for preventing falling is sleeved below the nut seat 203 of the screw rod 201 to prevent the nut seat 203 from passing out of the screw rod 201 .

[0047] To sum up, the outdoor parasol of the present invention adopts a double-layer column structure and a multi-layer hollow structure column, which can enhance the wind resistance of the outdoor parasol and is not easy to be broken; and the utility model adopts a method of setting a pulley 105 on the outside of the secondary column 104 and a guide groove 1011 on the inside of the main column 101, so that when the power unit 202 drives the secondary column 104 to move axially along the screw rod 201 and the main column 101 to open or close the umbrella ribs, the movement is smoother, and it is convenient to open or fold the outdoor parasol.
