Description

Technical Field

[0001] This utility model relates to a sunshade umbrella, and more particularly to a solar-powered sunshade umbrella. Background Technology

[0002] With the development of solar energy technology, photovoltaic power generation has been widely applied in daily life, such as in the field of outdoor sun umbrellas, leading to the development of outdoor solar sun umbrellas. Currently, most commercially available outdoor solar sun umbrellas typically use flexible solar cell chips (such as thin-film solar cells) directly bonded or sewn onto the umbrella fabric, thus achieving the dual functions of outdoor sunshade and solar energy collection. For example, Chinese utility model patent application number 201520811156.8 discloses a multifunctional solar sun umbrella with solar chips installed on the umbrella fabric. This application method presents the following problems: 1. Load-bearing capacity of the umbrella fabric: Solar chips (especially silicon-based or rigid thin-film batteries) have a certain weight. Directly placing them on the umbrella fabric increases the load on the surface, causing the fabric to sag and deform, affecting the flatness and wind resistance of the fabric. Long-term stress can also cause the seams of the fabric to tear, shortening the lifespan of the fabric. 2. Conflict between aesthetics and practicality: Solar chips are usually dark-colored or hard plate-like structures. Covering a large area can destroy the pattern design of the umbrella fabric, affecting the overall aesthetics. Furthermore, the reflection on the chip surface may cause light pollution, affecting the user experience. 3. Durability and maintenance issues: Frequent bending of the umbrella fabric during opening, closing, and wind exposure can easily cause the solder joints of the solar chips to break or the encapsulation layer to peel off, reducing power generation efficiency. In addition, long-term corrosion from rain and ultraviolet rays will accelerate the deterioration of the adhesive layer between the chip and the umbrella fabric, increasing maintenance costs. 4. Heat dissipation and safety hazards: Solar chips generate heat when working. If they are directly attached to the umbrella fabric, it may cause localized high temperatures, accelerating the aging of the umbrella fabric and even causing safety hazards (such as high-temperature burns or material melting). Summary of the Invention

[0003] The technical problem to be solved by this utility model is to provide an outdoor solar sunshade that is simple in structure, safe and stable in use, easy to maintain and has a good service life.

[0004] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows:

[0005] A solar-powered sunshade includes an umbrella body, which includes an umbrella frame. The umbrella frame includes multiple umbrella ribs for supporting the umbrella fabric and multiple support ribs for supporting the umbrella ribs. The umbrella fabric is disposed between adjacent umbrella ribs, so that the upper part of the umbrella ribs is exposed. At least one umbrella rib has a solar photovoltaic component for absorbing and converting solar energy on its upper part.

[0006] The solar photovoltaic component includes a solar chip, and the umbrella rib is provided with a corresponding mounting groove for embedding and installing the solar chip, and the solar chip is embedded in the corresponding mounting groove.

[0007] The umbrella ribs are provided with fixing grooves on two opposite sides for fixing the umbrella fabric, and the umbrella fabric is embedded and fixedly installed in the corresponding fixing grooves.

[0008] The solar photovoltaic component includes a solar cell, which is supported by a support bracket that is detachably mounted on the corresponding umbrella rib.

[0009] The support bracket includes a support part and a mounting part. The solar chip is mounted on the support part, and the mounting part is detachably mounted on the corresponding umbrella rib.

[0010] The umbrella rib is provided with a mounting groove at the installation position corresponding to the solar photovoltaic component, for the mounting part to be embedded and installed, and the mounting part is detachably installed in the mounting groove.

[0011] The mounting groove is provided with anti-detachment limiting walls on the left and right sides to prevent the solar photovoltaic component from detaching from the mounting groove. There is a solar energy receiving opening between the two anti-detachment limiting walls. At least one end of the mounting groove is open.

[0012] The mounting groove is an arc-shaped groove with an inwardly narrowing opening, and the mounting part is a cylindrical mounting part that mates with the arc-shaped groove. At least one end of the arc-shaped groove is open, and the cylindrical mounting part is connected to the bearing part by a connecting part. The width of the opening of the arc-shaped groove in the left-right direction is greater than the width of the connecting part in the left-right direction.

[0013] The mounting part includes two opposing clamping arms. Clamping ribs are protruding on two opposing inner end faces of the clamping arms. The umbrella ribs are correspondingly provided with clamping grooves that cooperate with the clamping ribs. The clamping ribs are embedded in the corresponding clamping grooves.

[0014] The supporting part includes a supporting base plate, and a retaining wall is provided on the left and right sides of the supporting base plate. The two retaining walls and the supporting base plate form a supporting cavity for supporting solar cells. The top of the retaining wall is bent inward to form a limiting part.

[0015] Compared with the prior art, the advantages of this utility model are:

[0016] (1) Set the umbrella fabric between adjacent umbrella ribs so that the part of the umbrella ribs that is higher than the umbrella fabric is exposed. Then the solar photovoltaic components can be fixed on the exposed umbrella ribs without contacting the umbrella fabric. This prevents the umbrella fabric from sagging or tearing due to the weight of the chips, and maintains the flatness and durability of the umbrella surface. In addition, the umbrella ribs and support ribs, as rigid support carriers, can bear the weight of the solar photovoltaic components and have better wind pressure resistance.

[0017] (2) When the umbrella is opened and closed, only the umbrella fabric itself bends. The solar photovoltaic components are not affected by mechanical stress because they are fixed on the umbrella frame, thus ensuring the stability and service life of the umbrella.

[0018] (3) The exposed upper part of the umbrella ribs is conducive to the heat dissipation of the solar photovoltaic components, thereby effectively ensuring the service life;

[0019] (4) It can retain the freedom of umbrella fabric design, and the patterns and colors can be designed freely without visual pollution;

[0020] (5) Solar photovoltaic components can be installed on some or all of the umbrella ribs as needed, balancing power generation demand and aesthetics;

[0021] (6) The solar photovoltaic components are separated from the umbrella fabric. When damaged, only the module on a single umbrella rib needs to be replaced. There is no need to disassemble the entire umbrella fabric, making it easy to maintain. Attached Figure Description

[0027] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0028] Example 1: As shown in the figure, a solar sunshade umbrella includes an umbrella body, which includes an umbrella frame. The umbrella frame includes multiple umbrella ribs 1 for supporting the umbrella fabric (not shown in the figure) and multiple support ribs 2 for supporting the umbrella ribs 1. The umbrella fabric is arranged between adjacent umbrella ribs 1, so that the upper part of the umbrella ribs 1 is exposed. At least one umbrella rib 1 has a solar photovoltaic component for absorbing and converting solar energy on its upper part.

[0029] In this specific embodiment, the solar photovoltaic component includes a solar chip 3, and the umbrella rib 1 is provided with a corresponding mounting groove 10 for embedding and installing the solar chip 3. The solar chip 3 is embedded and installed in the corresponding mounting groove 10. By providing mounting grooves 10 at corresponding installation positions for embedding and installing solar chips, the space of the main support frame 2 is rationally utilized while making full use of solar energy.

[0030] In this specific embodiment, anti-detachment limiting walls 101 are provided on the left and right sides of the mounting groove 10 to prevent the solar photovoltaic components from detaching from the mounting groove 10. A solar energy receiving opening 102 is provided between the two anti-detachment limiting walls 101, and at least one end of the mounting groove 10 is open. This ensures the stable installation of the solar chip 3 in the corresponding position and the stable absorption and conversion of solar energy. The openness at least one end of the mounting groove 10 facilitates the insertion and installation of the solar chip 3.

[0031] In this specific embodiment, two opposite sides of the umbrella rib 1 are provided with fixing grooves 11 for fixing the umbrella fabric, and the umbrella fabric is embedded and fixedly installed in the corresponding fixing grooves 11. This facilitates the fixed installation of the umbrella fabric.

[0032] To make full use of solar energy, solar photovoltaic components can be installed on each umbrella rib 1.

[0033] Example 2: The rest is the same as in Example 1, except that the solar photovoltaic component includes solar cells 3, which are supported by a support bracket 4. The support bracket 4 is detachably mounted on the corresponding umbrella rib 1, thus forming a modular design for the solar photovoltaic component.

[0034] In this specific embodiment, the support bracket 4 includes a support part 41 and a mounting part 42. The solar chip 3 is mounted on the support part 41, and the mounting part 42 is detachably mounted on the umbrella rib 1.

[0035] In this specific embodiment, an installation groove 10 is provided on the umbrella rib 1 at the installation position corresponding to the solar photovoltaic component, for the installation part 42 to be embedded and installed, and the installation part 42 is detachably installed in the installation groove 10.

[0036] In this specific embodiment, the mounting groove 10 is an arc-shaped groove with an inwardly narrowing opening, and the mounting part 42 is a cylindrical mounting part that mates with the arc-shaped groove. The cylindrical mounting part and the supporting part 41 are connected by a connecting part 43. The width of the opening of the arc-shaped groove in the left-right direction is greater than the width of the connecting part 43 in the left-right direction, and at least one end of the arc-shaped groove is open. Through the cooperation of the arc-shaped groove and the cylindrical mounting part 42, the angle of the supporting bracket 4 can be adjusted by rotating according to the angle of solar radiation, thereby achieving full absorption and conversion of solar energy. The openness at least one end of the arc-shaped groove facilitates the insertion and installation of the mounting part 42.

[0037] In this specific embodiment, the supporting part 41 includes a supporting base plate 411, and a retaining wall 412 is respectively provided on the left and right sides of the supporting base plate 411. The two retaining walls 412 and the supporting base plate 411 form a supporting cavity 413 for supporting the solar chip 3. The top of the retaining wall 412 is bent inward to form a limiting part 414. This can ensure the stable installation of the solar chip 3.

[0038] With this structure, the umbrella fabric does not need to be assembled piece by piece. Instead, a single piece of fabric can be used to cover the umbrella frame first. The solar photovoltaic modules are then inserted and installed. The fabric at this installation position is pressed between the mounting part 42 and the mounting groove 10, which improves assembly efficiency and achieves pre-positioning and pressing of the umbrella fabric.

[0039] Example 3: The rest of the parts are the same as in Example 2, except that the mounting part 42 includes two opposing clamping arms 421. Clamping ribs 422 are protruding from the two opposing inner end faces of the clamping arms 421. Correspondingly, the umbrella rib 1 has a corresponding groove 108 that mates with the clamping ribs 422. The clamping ribs 422 are embedded in the corresponding grooves 108. The structure is simple and easy to install and disassemble.
