[0004] The above structure increases the area of ​​the canopy by hinged secondary umbrella frames on both sides of the main umbrella frame, thus improving the sunshade space of the double-headed sun umbrella. However, because the canopy of the double-headed sun umbrella is larger, its wind resistance is poor in windy weather, affecting the user's use. Utility Model Content

[0005] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a double-headed umbrella. The technical problem this invention aims to solve is: how to address the poor wind resistance of existing double-headed umbrellas.

[0006] The objective of this utility model can be achieved through the following technical solutions:

[0007] A double-headed umbrella includes a main umbrella frame and auxiliary umbrella frames connected to the left and right sides of the main umbrella frame. The main umbrella frame includes multiple main upper umbrella ribs, and the auxiliary umbrella frames include multiple auxiliary upper umbrella ribs. The main umbrella frame and auxiliary upper umbrella ribs are characterized by having a long strip of main umbrella fabric connected to them. A long strip of ventilation opening is provided in the middle of the main umbrella fabric. The top ends of the main umbrella frame and auxiliary umbrella frames extend from the ventilation opening. A long strip of top umbrella fabric is connected to the top ends of the main umbrella frame and auxiliary umbrella frames, and the top umbrella fabric is located directly above the ventilation opening. Support components that support the outer ends of the top umbrella fabric upwards are connected to the main upper umbrella ribs and auxiliary upper umbrella ribs.

[0008] To improve the wind resistance of the double-headed umbrella, this application adopts a double-layer umbrella fabric structure. To ensure ventilation, a long, narrow vent is provided in the middle of the main umbrella fabric, with a top umbrella fabric positioned directly above it. A support component lifts the outer edge of the top umbrella fabric upwards. The larger vent increases the ventilation area of ​​the main umbrella fabric. In strong winds, the top umbrella fabric will tilt upwards, creating downward wind pressure and effectively preventing the main umbrella fabric from being blown over, thus further improving wind resistance. An air layer between the top and main umbrella fabrics also acts as a buffer in strong winds, reducing the direct impact of wind on the umbrella surface and providing good heat insulation, enhancing the practical comfort of the double-headed umbrella. In rainy weather, the top umbrella fabric can block rain and cover the vent without affecting the normal use of the double-headed umbrella. This allows the double-headed umbrella to improve wind resistance while also providing good rain protection and heat insulation, enhancing user comfort.

[0009] In the aforementioned double-headed umbrella, the outer edge of the top canopy is located on the outside of the ventilation opening wall.

[0010] The design of the top edge of the umbrella fabric prevents rainwater from entering the space below the umbrella fabric through the gap between the top and main fabrics during rainy weather, thus improving the rain protection effect of the double-headed umbrella without affecting its windproof effect.

[0011] In the aforementioned double-headed umbrella, the support assembly includes multiple support joints, which are connected to the main upper umbrella rib or the secondary upper umbrella rib. The upper end of the support joint is bent upward to form an arc-shaped connecting part, and the outer end of the connecting part extends outward to connect with the outer edge of the top umbrella fabric.

[0012] The support joint allows the outer edge of the top umbrella fabric to be tensioned by the support joint, eliminating the need for additional support rods on the main and secondary upper umbrella ribs. This facilitates the installation of the top umbrella fabric and provides stable support for its outer edge, creating a good air gap between the top umbrella fabric and the main umbrella fabric, thus improving its windproof performance.

[0013] In the aforementioned double-headed umbrella, an mounting sleeve is connected to the top umbrella fabric, and one end of the support connector is inserted into the mounting sleeve.

[0014] The installation sleeve design allows the top umbrella fabric to be easily attached to the support joint simply by fitting the installation sleeve onto it, making the installation and removal of the top umbrella fabric convenient.

[0015] In the aforementioned double-headed umbrella, both the main upper rib and the secondary upper rib are connected to connecting hooks, and the inner edge of the main umbrella fabric is connected to an elastic band corresponding to each connecting hook, with the elastic band hanging on the corresponding connecting hook.

[0016] The inner edge of the main umbrella fabric is also attached to the connecting hook via elastic bands, which facilitates the connection and disassembly of the main umbrella fabric and improves loading and unloading efficiency.

[0017] In the aforementioned double-headed umbrella, the support assembly includes multiple support rods. The top of the main umbrella frame is provided with a first support rib that supports the middle of the top umbrella fabric, and the top of the secondary umbrella frame is provided with a second support rib that supports both ends of the top umbrella fabric. The support rods hinge the first support rib to the main upper umbrella rib or hinge the second support rib to the secondary upper umbrella rib.

[0018] By setting a supporting umbrella rib one at the top of the main umbrella frame and a supporting umbrella rib two at the top of the secondary umbrella frame, the top umbrella fabric can be lifted upwards. In order to ensure the connection between the top umbrella fabric and the main and secondary upper umbrella ribs, it can be hinged by a support rod. This structure can also realize the installation of the top umbrella fabric, realizing a double-layer umbrella fabric structure.

[0019] In the aforementioned double-headed umbrella, the upper end of the support rod is located in the middle of either the first support rib or the second support rib.

[0020] The placement of the support rods provides good support.

[0021] In the aforementioned double-headed umbrella, LED beads or LED strips are connected to the main upper rib and the secondary upper rib.

[0022] The LED beads and LED strips can be powered by an external power source, improving the convenience of using the double-headed umbrella at night.

[0023] In the aforementioned double-headed umbrella, one or more solar panels are connected to the top of both the main umbrella frame and the top of the secondary umbrella frame, and the solar panels are electrically connected to LED beads or LED strips.

[0024] The installation of solar panels can directly provide power to LED beads or LED strips, thus saving energy. The number of solar panels can be selected according to needs to improve the power supply effect to LED beads and LED strips.

[0025] Compared with existing technologies, this double-headed umbrella has the following advantages: the larger ventilation openings increase the air vents of the main umbrella fabric. When the wind is strong, the top umbrella fabric will lift up, creating downward wind pressure, which effectively prevents the main umbrella fabric from being blown over, thereby further improving the windproof effect. It also creates an air layer between the top umbrella fabric and the main umbrella fabric, which can act as a buffer in strong winds, reducing the direct impact of the wind on the umbrella surface, and also provides better heat insulation, enhancing the practical comfort of the double-headed umbrella.
