Description

A special handrail for getting in and out of commercial vehicles Technical Field

[0001] This utility model relates to the field of automotive handrail technology, and in particular to a special handrail for getting in and out of commercial vehicles. Background Technology

[0002] In the daily use of commercial vehicles, handrails for getting on and off play a crucial role in passenger safety and convenience. Currently, existing handrails specifically designed for commercial vehicles generally have some design limitations.

[0003] The most common type is the simple straight-bar handrail, which is usually just a straight metal or plastic bar fixed directly to the inside of the car door. Its shape does not fully consider ergonomic principles, so passengers' hands cannot fit naturally when gripping it. After gripping for a long time, the area where the palm contacts the handrail will bear considerable pressure, which can easily cause soreness. This discomfort is more pronounced for passengers with weak hand strength or those who need to grip the handrail for extended periods, such as the elderly, children, or people with mobility impairments.

[0022] Figure 1 is a structural schematic diagram of the special handrail for getting on and off a commercial vehicle according to the present invention; Figure 2 is a structural schematic diagram of the special handrail for getting on and off a commercial vehicle according to the present invention. Please refer to Figures 1 and 2, which show a preferred embodiment. The handrail for getting on and off a commercial vehicle includes a handrail body 1. The handrail body 1 includes a connecting part 2, a first arc-shaped segment 3, a straight segment 4, a second arc-shaped segment 5, a first fixing part 6, a second fixing part 7, and a hook 8. One end of the connecting part 2 is provided with a first mounting hole 9. The other end of the connecting part 2 is connected to one end of the first arc-shaped segment 3. The other end of the first arc-shaped segment 3 is connected to one end of the second arc-shaped segment 5 through the straight segment 4. The other end of the second arc-shaped segment 5 is provided with a first fixing part 6. The straight segment 4 is provided with a second fixing part 7. The first fixing part 6 and the second fixing part 7 are both provided with second mounting holes 10. The connecting part 2 is provided with a hook 8. In this embodiment, the connecting part 2 is L-shaped and has a first mounting hole 9 for screws to be used to connect tightly to the corresponding position on the inside of the commercial vehicle door (e.g., interior panel). The screw specification needs to be reasonably selected according to the door material and the overall load-bearing capacity of the armrest to ensure the connection is firm. For example, if the door is made of metal, high-strength metal screws can be used to ensure sufficient tensile strength. The first arc segment 3 connects to the other end of the connecting part 2. Its arc is precisely designed by ergonomics to fit the natural bending shape of most passengers' hands when gripping, and the arc of the first arc segment 3 is greater than that of the second arc segment 5. The straight segment 4 connects to the first arc segment 3 and plays a key transition and support role, maintaining the overall stability of the armrest. Its length is determined according to the door size and the overall structural coordination. The second arc segment 5 connects to the other end of the straight segment 4, providing passengers with different grip angle options and further optimizing the grip experience. The other end of the second arc-shaped segment 5 is connected to the first fixing part 6, and the straight segment 4 is provided with a second fixing part 7. Both the first fixing part 6 and the second fixing part 7 are provided with second mounting holes 10, and are connected to the inside of the door again by screws, so as to realize a multi-point stable connection between the armrest and the door.

[0023] In this embodiment, the hook 8 is designed with one end bent to facilitate hanging various items, and its material is a high-strength metal with a certain degree of toughness to ensure that it can withstand items of a certain weight without deformation or damage. For example, the hook 8 can be made of stainless steel and has undergone surface treatment to enhance its rust resistance.

[0024] Furthermore, as a preferred embodiment, the connecting part 2, the first arc-shaped segment 3, the straight segment 4, the second arc-shaped segment 5, the first fixing part 6, and the second fixing part 7 are integrated into one piece, which can improve the overall stability of the handrail body 1.

[0025] Furthermore, as a preferred embodiment, the connecting part 2 is connected to the first arc-shaped segment 3, the first arc-shaped segment 3 is connected to the straight segment 4, the straight segment 4 is connected to the second arc-shaped segment 5, the second arc-shaped segment 5 is connected to the first fixing part 6, and the second fixing part 7 is connected to the straight segment 4 by screws. This facilitates the disassembly and replacement of the connecting part 2, the first arc-shaped segment 3, the straight segment 4, the second arc-shaped segment 5, the first fixing part 6, and the second fixing part 7.

[0026] Furthermore, as a preferred embodiment, it also includes an anti-slip strip 11. Mounting grooves are provided on both sides of the handrail body 1, and the anti-slip strip 11 is embedded in the mounting grooves. The anti-slip strip 11 is made of an anti-slip material, such as a mixture of rubber and anti-slip particles, which significantly increases friction. The anti-slip strip 11 is installed by being embedded in the grooves provided on both sides of the handrail body 1. During installation, the size of the groove must precisely match the anti-slip strip 11 to ensure a tight fit and prevent it from easily falling off. Moreover, to facilitate the replacement of the anti-slip strip 11, the groove design should consider the space for tool operation. For example, an opening can be provided at one end of the groove to facilitate the removal of the old anti-slip strip 11 and the insertion of the new one using a special tool.

[0027] Furthermore, as a preferred embodiment, both the first mounting hole 9 and the second mounting hole 10 are threaded holes, and the first mounting hole 9 and the second mounting hole 10 are respectively connected to the inner side of the car door by screws or bolts. Threaded connection holes for engaging with screws or bolts are provided at corresponding mounting positions on the inner side of the car door.

[0028] When installing the handrail, first determine the corresponding positions of the first mounting hole 9 on the connecting part 2 and the second mounting holes 10 on the first fixing part 6 and the second fixing part 7 on the inner side of the commercial vehicle door, based on the structure of the inner side of the door. Then, use drilling equipment to drill threaded connection holes on the door that are suitable for the size of screws or bolts. Before installing the screws or bolts, apply an appropriate amount of thread-locking adhesive to the threaded connection holes to enhance the fixing effect of the screws. Initially fix the connecting part 2 of the handrail to the door through the screws in the first mounting hole 9, and then connect the first fixing part 6 and the second fixing part 7 to the door in sequence with screws. After installation, test the handrail to check its overall stability. Test whether the handrail can be used normally by simulating passenger gripping and hanging items, and whether there is any interference or looseness between the components. If any problems are found, adjust the tightness of the screws or make minor adjustments to the components until the handrail can be used stably and safely.

[0029] The above description is only a preferred embodiment of the present utility model and does not limit the implementation method and protection scope of the present utility model. Those skilled in the art should realize that all solutions obtained by equivalent substitutions and obvious changes made based on the description and illustrations of the present utility model should be included within the protection scope of the present utility model.
