Description

Technical Field

[0001] The utility model relates to the technical field of moving walkways, and particularly relates to an aluminum alloy pedal for a moving walkway. Background Art

[0002] Moving walkways are common convenient facilities in modern urban transportation and large buildings, and the pedal is a key component of the moving walkway. Traditional moving walkway pedals are usually made of metal materials to ensure their strength and durability. However, with the development of technology and the pursuit of comfort by people, some deficiencies of the traditional pedal design have gradually emerged.

[0003] Existing moving walkway pedals are mainly in the shape of a rectangular frame, with a large amount of overall material used, resulting in a large overall weight, which easily leads to a large system load.

[0004] To solve these problems, the industry has been exploring new materials and structural designs. Aluminum alloy has become an ideal alternative material due to its light weight and high strength. However, how to design an aluminum alloy pedal that is both lightweight and strong is still an important challenge faced by the industry. Summary of the Utility Model

[0005] To solve the above problems, the utility model discloses an aluminum alloy pedal for a moving walkway.

[0006] To achieve the above object, the utility model provides the following technical solution: an aluminum alloy pedal for a moving walkway, comprising:

[0007] A support structure arranged on the back of the pedal body, the support structure comprising:

[0008] A first support plate connected between two main wheel seats;

[0009] A second support plate connected between two auxiliary fork seats;

[0010] Wherein, the tops of the first support plate and the second support plate are connected to the back of the pedal body for supporting the pedal body;

[0011] Both the first support plate and the second support plate are bent into an arc shape, and the middle parts of the first support plate and the second support plate are bent towards the middle part of the pedal body.

[0012] In addition, the front surface of the pedal body is an inwardly concave arc surface.

[0013] In a possible implementation manner, the support structure further comprises:

[0014] A longitudinal support plate is arranged at the middle part between the first support plate and the second support plate; wherein, the longitudinal support plate is respectively connected to both ends of the back surface of the pedal body, the first support plate and the second support plate, and is used to further support the pedal body.

[0015] In the above solution, the depression angle of the concave arc surface is.-°.

[0016] In the above solution, both ends of the longitudinal support plate are provided with inclined surfaces extending obliquely from the outside to the inside.

[0017] The solution of the embodiment of the present application forms a strong frame structure by arranging the first support plate and the second support plate, which are respectively connected to the main wheel seat and the auxiliary fork seat. This design enhances the overall stiffness and stability of the pedal, and effectively reduces deformation during use. Both the first support plate and the second support plate adopt an arc design, and the middle part is bent towards the middle part of the pedal body. This structural design further enhances the bending resistance of the pedal, can better disperse and transmit loads, and improves the load-bearing capacity of the pedal. Description of the Drawings

[0021] In order to make the purpose, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0022] The terms used in the following embodiments are only for the purpose of describing specific embodiments, and are not intended to limit the present utility model. As used in the specification and appended claims of the present utility model, the singular forms "a", "an", "the above", "the" and "this" are also intended to include, for example, the expression form of "one or more", unless clearly indicated to the contrary in the context.

[0023] References to "one embodiment" or "some embodiments" or the like described in this specification mean that a particular feature, structure, or characteristic described in connection with that embodiment is included in one or more embodiments of the present utility model. Thus, statements such as "in one embodiment", "in some embodiments", "in other some embodiments", "in still other embodiments", etc. that appear in different places in this specification do not necessarily all refer to the same embodiment, but mean "one or more but not all embodiments", unless otherwise specifically emphasized. The terms "comprising", "including", "having" and their variants all mean "including but not limited to", unless otherwise specifically emphasized.

[0024] Embodiment 1: As Figures 1 - 3 shown, an aluminum alloy pedal 100 for an escalator, comprising:

[0025] A support structure 103 disposed on the back surface 102 of the pedal body 101, the support structure 103 comprising:

[0026] A first support plate 104 connected between two main wheel seats 105;

[0027] A second support plate 106 connected between two auxiliary fork seats 107;

[0028] Wherein, the tops of the first support plate 104 and the second support plate 106 are connected to the back surface 102 of the pedal body 101 for supporting the pedal body 101;

[0029] Both the first support plate 104 and the second support plate 106 are bent into an arc shape, and the middle parts of the first support plate 104 and the second support plate 106 are bent towards the middle part of the pedal body 101.

[0030] In a specific solution, the pedal body 101 is made of a high-strength aluminum alloy material, such as 7075-T6 aluminum alloy. The thickness of the pedal body 101 can be designed according to actual requirements, usually between 10 - 15 mm. The surface of the pedal body 101 can be subjected to an anodizing treatment and anti-slip textures can be selectively added.

[0031] The support structure 103 includes a first support plate 104 and a second support plate 106. The thickness of these two support plates can be between 3 - 5 mm, and an aluminum alloy material the same as or similar to that of the pedal body is used. Both support plates are designed in an arc shape, and the middle parts thereof are bent towards the middle part of the pedal body 101. The radian can be designed according to the length of the pedal, and usually the arc height is between 5 - 10% of the pedal length.

[0032] The first support plate 104 and the second support plate 106 bear the load from both ends to the middle part of the pedal. At the same time, since the middle parts of the first support plate 104 and the second support plate 106 are both bent towards the middle part of the pedal body 101, the two gradually approach each other at their middle parts, further enhancing the support effect on the middle part of the pedal.

[0033] In addition, since the first support plate 104 is connected between the two main wheel seats 105, and the second support plate 106 is connected between the two auxiliary fork seats 107, the first support plate 104 provides a certain support for the two main wheel seats 105, and the second support plate 106 provides a certain support for the two auxiliary fork seats 107, making them more stable.

[0034] Embodiment 2: The front surface 108 of the pedal body 101 is a concave arc surface.

[0035] Specifically, the depression angle of the concave arc surface 108 is 0.5 - 2°.

[0036] The front surface 108 of the pedal body 101 is designed as a concave arc surface. This concave surface design means that the pedal surface is slightly concave from both sides to the middle, forming a very shallow "bowl" - shaped structure.

[0037] In a possible implementation manner, the depression angle of the concave arc surface 108 can be controlled between 0.5 - 2°.

[0038] Among them, 0.5°: the minimum depression angle, suitable for shorter pedals or scenarios with higher requirements for flatness.

[0039] 2°: the maximum depression angle, suitable for longer pedals or scenarios that require a more obvious anti - slip effect.

[0040] 1 - 1.5°: the recommended angle under normal circumstances, which can achieve a good balance between safety and comfort.

[0041] The concave surface design utilizes the natural sinking characteristic of the human center of gravity. When a person stands on the concave surface, the feet will naturally tilt towards the middle. Thus, it is beneficial to reduce the risk of passengers slipping, especially when the moving walkway starts, stops, or suddenly accelerates or decelerates.

[0042] Embodiment 3: As Figures 2 - 3 shown, the support structure 103 further includes:

[0043] A longitudinal support plate 109, arranged at the middle part of the first support plate 104 and the second support plate 106; wherein, the longitudinal support plate 109 is respectively connected to both ends of the back surface 102 of the pedal body 101, the first support plate 104, and the second support plate 106, and is used to further support the pedal body 101.

[0044] The longitudinal support plate 109 is made of the same or similar high-strength aluminum alloy material as the pedal body 101, such as 7075-T6 aluminum alloy. It can adopt a "T" - shaped or "I" - shaped cross - section to increase the stiffness. It is arranged in the middle part of the first support plate 104 and the second support plate 106. It is arranged along the longitudinal center line of the pedal body 101. The longitudinal support plate 109 and the first support plate 104 and the second support plate 106 form an "H" - shaped structure, which can reduce the bending deformation of the pedal during operation and improve the stability of the overall structure.

[0045] Both ends of the longitudinal support plate 109 are formed with inclined surfaces 110 that extend obliquely from the outside to the inside. By removing the materials in non - critical areas, local weight reduction is achieved. While ensuring the strength, the structural weight is slightly reduced, which is beneficial to the improvement of the overall performance.

[0046] The technical means disclosed in the solution of the present utility model are not limited to the technical means disclosed in the above - mentioned embodiments, but also include the technical solutions composed of any combination of the above - mentioned technical features. It should be noted that for those of ordinary skill in the art of this technology, without departing from the principle of the present utility model, several improvements and refinements can be made, and these improvements and refinements are also regarded as the protection scope of the present utility model.
