[0011] The utility model is further provided with: the material of the metal plate is metal iron.

[0012] The welding process is ultrasonic welding.

[0013] The utility model discloses beneficial effect is:

[0014] 1. The metal plate is formed with the first structure layer and the second structure layer through bending, and the integrated forming mode reduces the number of parts and assembly procedures, reduces the processing difficulty and cost, improves the production efficiency, the welding of the second structure layer and the top of the first structure layer is relatively simple, and is relatively easy to realize in production and installation site, and the structure is firm after welding, is favorable to guarantee installation quality and speed, the U-shaped groove of the first structure layer provides good mechanical support, can disperse the pressure that sunshade bears, guarantees the stability of sunshade overall structure, the second structure layer and the top of the first structure layer are welded and form closed space, similar box type structure, greatly enhance the bending and torsional resistance of crossbeam, improve the overall rigidity of crossbeam, the bending part of connecting surface increases

[0015] The connecting area and connecting strength of the first structure layer and the second structure layer make the two-layer structure more closely combined, and the cooperative work ability is stronger, and the overall strength of the crossbeam structure is further improved.

[0016] 2. The bending part one end and the connecting surface bending angle near the welding point are greater than 90 degrees, and the other end is 90 degrees bending, and the asymmetric angle design makes when combining with the first structure layer, the second structure layer, can exert force on two-layer structure from different directions, better offset external force influence, like under the pressure of transverse wind load or heavy, avoid the connecting surface to appear loose, separate and other conditions, strengthen the stability of the overall connection. When the height of the bending part and the connecting surface is less than 1 / 3 of the height of the second structure layer, the overall structural strength is reduced, and the force transmitted from each structure layer cannot be effectively received. When the height of the bending part and the connecting surface is greater than 1 / 2 of the height of the second structure layer, deformation is easy to occur under the action of external force, resulting in structure damage. Therefore, the height of the bending part and the connecting surface is between 1 / 3 and 1 / 2 of the height of the second structure layer, which can effectively receive and transmit the force from the first structure layer, the second structure layer and other parts of the sunshade, so that the force can be more evenly distributed to the entire crossbeam structure, preventing local stress from being too large and causing structure damage, and ensuring the reliability of the crossbeam structure during long-term use.

[0017] 3. The bending part is located in the middle of the connecting surface and is equidistant from both ends, so that the bending part can evenly transmit force to both ends of the second structural layer when stressed, avoiding problems such as structural deformation, damage, etc. due to uneven stress, ensuring the balance and stability of the overall force of the entire second structural layer and the beam structure. The circular arc-shaped bending design can effectively avoid stress concentration compared to straight angle bending and other methods. When subjected to external force, the force can be smoothly dispersed along the circular arc, reducing the risk of excessive local stress, making the bottom bending part of the first structural layer more solid and durable, prolonging the service life of the beam structure. In order to further enhance the safety of the entire sunshade structure, the reinforcing rib formed by the bending can significantly enhance the strength of the bottom of the first structural layer, preventing deformation or damage to the bottom end of the first structural layer during installation or placement, affecting installation efficiency.

[0018] 4. The entire metal plate is subjected to rust prevention treatment, and the rust prevention treatment method is electroplating or spraying process, which can form a protective film on the surface of the metal iron material, slow down the corrosion speed of the metal, greatly prolong the service life of the metal plate made of the beam structure, reduce the maintenance and replacement cost caused by rust, and metal iron is a relatively common and relatively low-cost metal material. Selecting it to make the beam structure can effectively control the production cost on the basis of ensuring certain strength and performance, so that the sunshade product has better price competitiveness in the market, and is more conducive to large-scale production and popularization and application. Compared with some traditional welding processes, ultrasonic welding is a high-efficiency and high-quality welding method, which can realize tight and firm connection between metal plates, has high strength and good sealing property at the welding position, and can complete the welding operation in a short time, which helps to improve production efficiency and shorten production cycle, thereby effectively reducing labor cost and improving production benefit when producing sunshade beam structures in batches.

It will be understood that the spatially relative terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if a device in the figures is inverted, elements described as being on the "lower" side of other elements or features would then be oriented on "upper" sides thereof, and vice versa. Thus, the exemplary term "lower" can encompass both an orientation of above and below. The devices can be otherwise oriented (rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly.

[0024] Also, the terms "first" and "second" are used herein only to distinguish one element from another element having a same name, and do not necessarily require or imply any such actual relationship or order between or among the elements.

[0025] Figs. 1 to 2 The illustrated beam structure of a sunshade comprises a metal plate 1, the metal plate 1 is bent to form a first structure layer 2 and a second structure layer 3, the one-piece forming manner reduces the number of parts and assembly procedures, reduces the processing difficulty and cost, and improves the production efficiency, the first structure layer 2 is composed of a U-shaped groove 4 formed by bending one end of the metal plate 1, which provides good mechanical support and can disperse the pressure borne by the sunshade, so that the sunshade is less likely to deform when bearing its own weight and external loads such as wind blowing and snow accumulation, thereby ensuring the stability of the overall structure of the sunshade, the second structure layer 3 is composed of the other end of the metal plate 1 bent to the top of the first structure layer 2 and welded to the top of the first structure layer 2 to form a closed space, the welding of the second structure layer 3 to the top of the first structure layer 2 is relatively simple and can be easily realized on the production and installation site, and the second structure layer 3 has a box-shaped structure, which greatly enhances the bending resistance and torsional resistance of the beam and improves the overall rigidity of the beam, the first structure layer 2 and the second structure layer 3 have a common connecting surface 5, the connecting surface 5 is provided with a bent portion 6, the bent portion 6 of the connecting surface 5 increases the connecting surface 5 and the connecting strength of the first structure layer 2 and the second structure layer 3, so that the two layers of structure are more closely combined and have stronger synergistic working capacity, and the overall strength of the beam structure is further improved.

[0026] One end of the bent portion 6 is bent at an angle greater than 90 degrees with respect to the connecting surface 5 near the welding point, and the other end is bent at an angle of 90 degrees with respect to the connecting surface 5, such an asymmetric angle design enables the application of force to the two layers of structure from different directions when the first structure layer 2 and the second structure layer 3 are combined, thereby better offsetting the influence of external force, such as when bearing a transverse wind load or a heavy object pressing downward, to avoid the loosening and separation of the connecting surface 5, and to strengthen the stability of the overall connection.

[0027] When the height of the bending part and the connecting surface 5 is less than 1 / 3 of the height of the second structural layer 3, the overall structural strength is reduced, and the force transmitted from each structural layer cannot be effectively received; when the height of the bending part and the connecting surface 5 is greater than 1 / 2 of the height of the second structural layer 3, deformation is easily caused by external force, resulting in structural damage; therefore, the height of the bending part and the connecting surface 5 is between 1 / 3 and 1 / 2 of the height of the second structural layer 3, which can effectively receive and transmit the force from the first structural layer 2, the second structural layer 3 and other parts of the sunshade, so that the force can be more evenly distributed to the entire beam structure, preventing local stress from being too large and causing structural damage, and ensuring the reliability of the beam structure during long-term use.

[0028] The bending part 6 is located in the middle of the connecting surface 5, and the distance to the two ends of the second structural layer 3 is equal, so that the bending part 6 can evenly transmit the force to the two ends of the second structural layer 3 when stressed, avoiding problems such as structural deformation and damage caused by uneven stress on one end, and ensuring the balance and stability of the entire second structural layer 3 and the overall beam structure.

[0029] The bending part of the bottom of the first structural layer 2 is in a circular arc shape 7, which can effectively avoid stress concentration compared to a right-angle bending or other methods, and when subjected to external force, the force can be smoothly dispersed along the circular arc, reducing the risk of excessive local stress, making the bottom bending part of the first structural layer 2 more solid and durable, and prolonging the service life of the beam structure.

[0030] The bottom of the first structural layer 2 is further enhanced in safety, and the end of the bottom of the first structural layer 2 is bent to form a reinforcing rib 8, which can significantly enhance the strength of the bottom of the first structural layer 2, prevent deformation or damage of the end of the bottom of the first structural layer 2 during installation or placement, and affect the installation efficiency.

[0031] The entire metal plate 1 is subjected to rust prevention treatment, and the rust prevention treatment method is electroplating or spraying process, which can form a protective film on the surface of the metal iron material, slow down the corrosion speed of the metal, greatly prolong the service life of the beam structure made of the metal plate 1, and reduce the maintenance and replacement cost caused by rust.

[0032] The metal plate 1 is made of metal iron, which is a relatively common and relatively low-cost metal material, and can effectively control the production cost on the basis of ensuring certain strength and performance, so that the sunshade product has better price competitiveness in the market, and is more conducive to large-scale production and popularization and application.
