[0033] In order to help those skilled in the art better understand the present invention, the following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of the present invention.

[0034] As described in the background art, traditional elevator door panel designs often adopt a flat plate structure. Although simple to manufacture, it is prone to deformation or damage when faced with accidental impact or long-term stress, thereby affecting the normal operation of the elevator and the passengers' sense of security.

[0035] In order to solve this technical problem, the utility model provides an elevator door panel reinforcement rib, which is used to reinforce the elevator door panel.

[0036] Specifically, please refer to Figure 1-3 , the elevator door panel reinforcement specifically includes:

[0037] The reinforcing rib assembly 1 is provided with a trapezoidal reinforcing portion 2 , which is bent toward the inside of the reinforcing rib assembly 1 .

[0038] The elevator door panel reinforcement provided by the utility model, through the reinforcement rib assembly 1 set up in this application, when the reinforcement rib assembly 1 is installed on the elevator door panel, can improve the strength of the elevator door panel, thereby enhancing the overall impact resistance and reducing the risk of deformation caused by impact; the design of the trapezoidal reinforcement part 2 makes the stress distribution of the reinforcement rib assembly 1 more uniform, reduces local stress concentration, and extends the service life of the door panel.

[0039] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0040] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features and technical solutions therein can be combined with each other.

[0041] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings.

[0042] Example 1, please refer to Figure 1 , an elevator door panel reinforcement, including a reinforcement rib assembly 1, a trapezoidal reinforcement portion 2 is provided on the reinforcement rib assembly 1, and the trapezoidal reinforcement portion 2 is bent toward the inner side of the reinforcement rib assembly 1; the reinforcement rib assembly 1 set in this application, when the reinforcement rib assembly 1 is installed on the elevator door panel, can improve the strength of the elevator door panel, thereby enhancing the overall impact resistance and reducing the risk of deformation caused by impact; the design of the trapezoidal reinforcement portion 2 makes the stress distribution of the reinforcement rib assembly 1 more uniform, reduces local stress concentration, and extends the service life of the door panel.

[0043] Further, such as Figure 1-Figure 2 As shown, the reinforcement rib assembly 1 includes two second reinforcement plates 103, and the trapezoidal reinforcement part 2 is arranged between the two second reinforcement plates 103; the trapezoidal reinforcement part 2 includes two fourth reinforcement plates 202, and the two fourth reinforcement plates 202 are fixedly connected to the two second reinforcement plates 103 respectively, and a third reinforcement plate 201 is fixedly connected between the two fourth reinforcement plates 202. The trapezoidal reinforcement part 2 is arranged in a trapezoidal shape. The trapezoidal cross-section has unique advantages in structure. Compared with traditional rectangular or circular cross-sections, the trapezoidal cross-section can better disperse stress when subjected to external force. This is because the shape of the trapezoidal cross-section makes it have different bending stiffness in different directions, so that when subjected to external force, the stress can be more evenly distributed over the entire cross-section instead of being concentrated in a certain local area. This ability to disperse stress helps to reduce local stress concentration and reduce the risk of damage to the door panel due to excessive stress.

[0044] The principle of the trapezoidal reinforcement scheme is to improve the bearing capacity of the structure under the same load by increasing the cross-sectional area of ​​the component. Specifically, the trapezoidal cross-section can effectively improve the bending and shear resistance of the structure and reduce the possibility of bending deformation and shear failure of the structure. In addition, the trapezoidal cross-section can also increase the stiffness and stability of the component and improve the overall seismic performance of the structure.

[0045] Further, such as Figure 1-Figure 2 As shown, the two second reinforcing plates 103 are fixedly connected to the first reinforcing plate 101 on one side away from each other, and the two first reinforcing plates 101 are fixedly connected to the connecting plate 102 on one end away from the second reinforcing plate 103. The connecting plate 102 is used to fit the elevator door panel. During installation, the connecting plate 102 can be welded to the elevator door panel to achieve the connection between the reinforcement rib assembly 1 and the elevator door panel.

[0046] Furthermore, the first reinforcing plate 101, the connecting plate 102, the second reinforcing plate 103, the third reinforcing plate 201 and the fourth reinforcing plate 202 are arranged as an integrated whole; the integrated arrangement avoids connection gaps and weak points between the components. When subjected to force, the force can be transmitted more smoothly in the entire reinforcing rib structure, and there will be no loss of energy or structural damage due to loosening, deformation or breakage of the connection parts.

[0047] Further, such as Figure 3 As shown, a plurality of through holes 4 are provided on the connecting plate 102. The provision of the through holes 4 allows components such as bolts or rivets to pass through the through holes 4 to achieve connection with the elevator door panel. If welding is used for connection, the provision of the through holes 4 facilitates increasing the welding points between the connecting plate 102 and the elevator door panel, thereby improving the stability of the welding between the connecting plate 102 and the elevator door panel.

[0048] Furthermore, a reinforcement piece is provided on the inner side of the reinforcing rib assembly 1, and the provision of the reinforcement piece can further improve the strength of the present application.

[0049] Example 2 further optimizes the elevator door panel reinforcement provided in Example 1. Specifically, Figure 3 As shown, the reinforcement is a filling body 3, the surface of the filling body 3 is fixedly connected to the first reinforcing plate 101, the second reinforcing plate 103, the third reinforcing plate 201 and the fourth reinforcing plate 202. The setting of the filling body 3 can improve the strength of the reinforcing rib assembly 1 and the trapezoidal reinforcement part 2, thereby improving the reinforcement effect of the elevator door panel. The filling body 3 can be made of glass fiber reinforced plastic. The glass fiber reinforced plastic filling body has good chemical stability and corrosion resistance, and can resist the erosion of the reinforcing rib assembly by environmental factors. During long-term use, the performance will not be reduced due to factors such as moisture and oxidation.

[0050] Example 3 further optimizes the elevator door panel reinforcement provided in Example 1. Specifically, Figure 4 As shown, the reinforcement includes several first support plates 5, which are arranged on the inner side of the reinforcement rib assembly 1, and the outer surface of the first support plate 5 is fixedly connected to the first reinforcement plate 101, the second reinforcement plate 103, the third reinforcement plate 201 and the fourth reinforcement plate 202. The first support plate 5 can be used to reinforce the interior of the reinforcement rib assembly 1 to improve the firmness of the reinforcement rib assembly 1, thereby improving the reinforcement effect of the elevator door panel.

[0051] Further, such as Figure 4 As shown, the first support plate 5 is pasted with a double-sided adhesive 6 on one side away from the third reinforcing plate 201, and the double-sided adhesive 6 is connected to a release film 601 on one side away from the first support plate 5. The setting of the release film 601 can isolate and protect the double-sided adhesive 6 before use, thereby reducing the dust sticking to the double-sided adhesive 6. When the double-sided adhesive 6 is used, the first support plate 5 can be pasted to the elevator door panel to achieve the connection between the first support plate 5 and the elevator door panel.

[0052] Example 4 further optimizes the elevator door panel reinforcement provided in Example 1. Specifically, Figure 5 As shown, the reinforcement includes a second support plate 7, which is located on the inner side of the reinforcement rib assembly 1, and the second support plate 7 is fixedly connected to one side of the third reinforcement plate 201, and the side of the second support plate 7 away from the third reinforcement plate 201 is fixedly connected to the widening plate 701; a plurality of side openings 8 are opened on the side wall of the first reinforcement plate 101, and the trapezoidal reinforcement part 2 can be supported and reinforced by the second support plate 7 and the widening plate 701. The setting of the side openings 8 makes it possible to use a welding rod to pass through the side openings 8 to weld the widening plate 701 to the elevator door, so as to realize the connection between the widening plate 701 and the elevator door panel.
