[0030] The present utility model will be described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the aspects described below in conjunction with the accompanying drawings and specific embodiments are merely exemplary and should not be construed as imposing any limitation on the protection scope of the present utility model.

[0031] In the description of the present utility model, it should be noted that unless otherwise clearly specified and defined, the terms "installation", "connection", and "coupling" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0032] In addition, the "upper", "lower", "left", "right", "top", "bottom", "horizontal", and "vertical" used in the following description should be understood as the orientations shown in this section and the relevant accompanying drawings. Such relative terms are only for convenience of description and do not represent that the devices described need to be manufactured or operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model.

[0033] It can be understood that although terms such as "first", "second", and "third" can be used herein to describe various components, regions, layers, and / or parts, these components, regions, layers, and / or parts should not be limited by these terms, and these terms are only used to distinguish different components, regions, layers, and / or parts. Therefore, the first component, region, layer, and / or part discussed below can be referred to as the second component, region, layer, and / or part without departing from some embodiments of the present utility model.

[0034] As described above, the existing handrails for public transportation vehicles are mainly made of metal materials such as stainless steel, aluminum alloy, or carbon steel. Such handrails are relatively heavy and are prone to plastic deformation due to metal fatigue. In another existing technology, the handrail uses carbon fiber material, which helps to achieve the lightweight of the handrail, but the cost of carbon fiber material is relatively high.

[0035] The present utility model provides a handrail for public transportation vehicles, which can achieve lightweight while preventing the deformation of the handrail and reducing the manufacturing cost of the handrail.

[0036] The handrail for public transportation vehicles may include a hollow handrail rod and a handrail connector, and the handrail connector can be used for the installation and fixation of the hollow handrail rod and the load transfer.

[0037] Please refer to Figure 1 , Figure 1 which shows a schematic diagram of a hollow handrail rod provided according to some embodiments of the present utility model.

[0038] As shown Figure 1 in the figure, the hollow handrail rod 100 can be a hollow circular tube with a diameter of 32 - 38 mm. The hollow inside the hollow handrail rod 100 is formed by a wrapping layer. The wrapping layer is a composite structure, including a surface layer 110 and an inner layer 120. The surface layer 110 wraps around the outside of the inner layer 120, and the hollow inside the inner layer can be formed without adding a support structure inside. The surface layer 110 is made of carbon fiber material, and the inner layer 120 is made of a lightweight metal material (such as aluminum alloy, titanium alloy, etc.). Preferably, the hollow handrail rod 100 can use aluminum alloy material as the material of the inner layer 120.

[0039] Through the composite structure formed by the surface layer of carbon fiber material and the inner layer of aluminum alloy material, the hollow handrail rod can achieve the lightweight of the handrail. And, by wrapping a surface layer of carbon fiber material outside the inner layer of aluminum alloy material, the plastic deformation of the inner layer of aluminum alloy material can be effectively prevented. In addition, the carbon fiber material is only used to wrap the inner layer of aluminum alloy material, and compared with the handrail made of carbon fiber material, the hollow handrail rod with the composite structure has a lower cost.

[0040] In another preferred embodiment, the cross-section of the hollow handrail rod can also be other shapes, such as square, triangular, etc., not limited to the Figure 1 circular shape in the illustrated embodiment.

[0041] Thus, through the hollow handrail rod, the handrail provided by the present utility model has a significant lightweight effect compared with the existing handrails made of stainless steel, aluminum alloy, and carbon steel materials, and the weight is reduced by about 60%. And, no other reinforcement structures or support structures need to be added inside the hollow handrail rod, which can further enhance the lightweight effect.

[0042] The handrail connector for the installation and fixation of the hollow handrail rod and load transfer can be a connector made of metal material. Through the handrail connector, the hollow handrail rod is fixed on the vehicle. Preferably, the metal material of the handrail connector can be aluminum alloy material, stainless steel material, or carbon steel material.

[0043] Please refer to Figure 2 and Figure 3 , Figure 2 and Figure 3 which show schematic diagrams of handrail connectors provided according to some embodiments of the present utility model.

[0044] In Figure 2In the illustrated embodiment, the inner layer of the hollow armrest rod is made of aluminum alloy, and the surface layer is made of carbon fiber. The armrest connector 210 is connected to the welding position A at one end of the carbon fiber surface layer 220 and the aluminum alloy inner layer 230 of the hollow armrest rod by welding, so as to realize the connection with the hollow armrest rod. Further, the other end of the armrest connector 210 is connected to the vehicle (not shown). Thus, the connection between the hollow armrest rod and the vehicle can be realized through the armrest connector 210, and the force applied by the passenger to the hollow armrest rod can be transmitted to the vehicle.

[0045] Similarly, in another embodiment, as Figure 3 shown, the armrest connector 310 can also be installed and fixed at the bolt fixing position B at one end of the carbon fiber surface layer 320 and the aluminum alloy inner layer 330 of the hollow armrest rod by bolt connection, so as to realize the connection between the hollow armrest rod and the vehicle through the armrest connector 310, and thus transmit the force applied by the passenger to the hollow armrest rod to the vehicle.

[0046] In summary, the armrest for a public transportation vehicle provided by the present utility model can achieve lightweight while preventing the deformation of the armrest and reducing the manufacturing cost of the armrest.

[0047] The foregoing description of the disclosure is provided to enable any person skilled in the art to make or use the disclosure. Various modifications to the disclosure will be readily apparent to those skilled in the art, and the general principles defined herein may be applied to other variations without departing from the spirit or scope of the disclosure. Thus, the disclosure is not intended to be limited to the examples and designs described herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
