Description

Technical Field

[0001] This utility model belongs to the technical field of bus assembly parts, specifically relating to a handrail structure for buses. Background Technology

[0002] City buses typically have handrails inside for passengers to hold onto. These handrails are usually made of hollow aluminum alloy or steel tubing. In winter, they can be quite cold, resulting in a poor passenger experience. To address this issue, manufacturers usually wrap the handrail tubing with a rubber sleeve. While this sleeve can reduce the coldness to some extent, it doesn't completely solve the problem and can be unsightly and prone to peeling off. Utility Model Content

[0003] The purpose of this utility model is to provide a handrail structure for buses to solve the problem of cold handrails inside buses in winter, while maintaining the aesthetics of the handrails.

[0004] The technical solution adopted by this utility model is a handrail structure for a passenger vehicle, including a handrail bar installed between the roof and the floor of the vehicle body. A heating component is provided inside the handrail bar. The heating component includes a disc, a heating wire, and a support rod. At least two discs are fixedly installed inside the handrail bar at a set distance apart. The support rod is fixedly installed between the discs. The heating wire is spirally wound around the support rod and its end is connected to a wire. The wire passes through the disc and is connected to the vehicle body circuit.

[0005] Furthermore, the aforementioned handrail is made of hollow aluminum alloy tube or hollow steel tube with a wall thickness of 2-3mm. The top and bottom ends of the handrail are fixedly connected to the roof and floor of the vehicle body with bolts, respectively, and a round hole is opened on the floor of the vehicle body directly opposite the bottom end of the handrail.

[0006] Furthermore, the aforementioned disc has a thickness of 5-10mm, and its outer diameter is adapted to the inner diameter of the handrail. Multiple connection holes are opened on the handrail, and threaded holes are opened on the outer wall of the disc corresponding to the connection holes. Bolts are used to fix the disc inside the handrail through the connection holes and threaded holes.

[0007] Furthermore, a wire hole is opened in the center of the aforementioned disc, through which the wire passes. Mounting holes are provided on both sides of the wire hole for mounting support rods.

[0008] Compared with the prior art, the beneficial effects of this utility model are that by setting a heating component inside the handrail, the heating wire of the heating component generates heat and conducts the heat to the handrail, thus heating the handrail and maintaining a suitable temperature in winter. This solves the problem of passengers' poor experience due to the cold handrail when holding it in winter. At the same time, it maintains the smooth metallic appearance of the handrail, which has the advantages of being beautiful and simple. Attached Figure Description

[0012] The present invention will be further explained below with reference to the accompanying drawings to enable those skilled in the art to better understand it.

[0013] Example 1

[0014] like Figure 1-3 As shown, a handrail structure for a passenger vehicle includes a handrail 3 installed between the vehicle roof 1 and the floor 2. The handrail 3 is made of hollow round tube of aluminum alloy or steel material with a wall thickness of 2-3mm. The top end of the handrail 3 is fixedly connected to the vehicle roof 1 with bolts, and the bottom end is fixed to the vehicle floor and the vehicle floor 2 with bolts. A round hole is opened in the vehicle floor 2 opposite to the bottom end of the handrail 3.

[0015] The handrail 3 is equipped with a heating element 4, which includes a disc 41, a heating wire 42, a support rod 43, and a wire 44. The disc 41 is made of a non-metallic material with insulating properties and has a circular structure. The thickness of the disc 41 is 5-10mm, and its outer diameter is adapted to the inner diameter of the handrail 3. A wire hole 412 is opened in the center of the disc 41, and mounting holes 413 are provided on both sides of the wire hole 412. Threaded holes 411 are opened on the outer wall of the disc 41. Multiple connection holes are opened on the handrail 3 corresponding to the threaded holes 411. Bolts are used to fix the disc 41 inside the handrail 3 through the connection holes and threaded holes 411. Countersunk bolts are used to prevent the disc from protruding from the surface of the handrail 3 after installation and affecting the feel. At least two discs 41 are fixedly installed inside the handrail 3 at a set distance. Two support rods 43 are fixedly installed between the discs 41 through mounting holes 413. The heating wire 42 is made of a metal material with high resistance. It is spirally wound around the support rod 43 and its two ends are connected to the wires 44. The wires 44 are ordinary wire harnesses with insulation. One end of the heating wire 42 is fixed on the disc 41, and the other end of the wire 44 passes through the wire hole 412, passes through the disc, and is arranged along the bottom of the handrail 3. It extends out from the round hole in the vehicle floor 2 and is connected to the vehicle circuit.

[0016] A handrail structure for buses, composed of the aforementioned components, can be equipped with multiple heating elements installed in the handrail's 3-cavity structure as needed. These heating elements are controlled by a switch or logic circuit located in the driver's area. Once the circuit is connected, the heating wire heats up the handrail, thus solving the problem of cold handrails inside the vehicle.

[0017] The embodiments described above are merely preferred embodiments of the present invention and are not intended to limit the scope of the present invention. Various modifications and improvements made by those skilled in the art to the technical solutions of the present invention without departing from its design spirit and principles should fall within the protection scope defined by the claims of the present invention.
