Description

Technical Field

[0001] This utility model relates to the field of handrail equipment technology, specifically a plastic handrail for vehicle roof. Background Technology

[0002] In automobiles, roof grab bars are essential to provide handrails for passengers when the car is not moving smoothly. However, in the current technology, automotive plastic grab bars are fixed one-piece designs, which are difficult to disassemble and do not facilitate replacement and maintenance. Over time, bacteria can accumulate on the grab bars.

[0003] For example, the authorized patent document with application number CN202121811862.7 discloses a foldable roof grab handle, which includes a grab handle rod installed on the roof via a folding mechanism. The folding mechanism includes multiple support rods evenly spaced on the roof, with folding rods hinged to the support rods. The upper end of each folding rod is hinged to the grab handle rod, allowing the grab handle rod to move up and down. When the grab handle rod reaches its highest and lowest points, it is respectively limited by a first connecting member and a second connecting member. The beneficial effects of this utility model are: avoiding the risk of people falling from heights on the roof without paying attention; and that the grab handle rod can be placed on the roof when folded, without affecting vehicle height restrictions. It can smoothly pass through some bridges, tunnels, culverts, and other construction facilities in China where vehicle height requirements are strict.

[0004] The aforementioned patents show that the plastic handrails used in vehicles are fixed in one piece, making disassembly difficult and inconvenient for replacement and maintenance. Therefore, we need to provide a plastic handrail for the roof of a vehicle. Utility Model Content

[0005] The purpose of this utility model is to provide a plastic roof handrail for vehicles. When the plastic handrail needs to be removed, two pushing blocks at the top of the handrail post are pushed closer together. The pushing blocks slide in a groove, causing a limiting post to move in a circular groove and compress a spring. One end of the limiting post is disengaged from the handrail rocker arm, allowing the handrail post to be removed from the two handrail rocker arms for replacement and maintenance. Both pushing blocks have integrally machined protrusions at their tops to enhance friction during movement. The telescopic rod is located inside the spring, preventing it from bending and becoming unusable. An LED light strip is installed at the handrail rocker arm, and its on / off state can be controlled by a switch to provide interior lighting. This addresses the problem of fixed, one-piece plastic handrails in the prior art, which are difficult to disassemble and lack convenient replacement and maintenance.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figures 1-4 This utility model provides a technical solution: a plastic roof grab handle for vehicles, comprising:

[0027] Handrail post 1, and circular grooves 2 formed at both ends of handrail post 1;

[0028] Limiting posts 4 are installed inside both circular grooves 2 via snap-fit ​​parts 3;

[0029] Handrail rocker arms 5 are slidably mounted on the surfaces of both limiting posts 4;

[0030] The tops of the two armrest rocker arms 5 are fixed to the roof by mounting pieces 6;

[0031] The snap-fit ​​component 3 includes a spring 31 snapped into the inside of the circular groove 2. One end of the spring 31 is snapped into one end of the limiting post 4. The top of the limiting post 4 is integrally machined with a push block 32. The top of the push block 32 passes through the top of the handrail post 1 and extends therein. The top of the handrail post 1 is provided with a sliding groove 33 for the push block 32 to slide. The sliding groove 33 is connected to the circular groove 2.

[0032] The tops of the two push blocks 32 are integrally machined with protruding strips, and the spring 31 is movably sleeved with a telescopic rod 7, which is located between the inner wall of the circular groove 2 and one end of the limiting post 4.

[0033] In this embodiment, when the plastic handrail needs to be removed, the two push blocks 32 at the top of the handrail column 1 are pushed closer to each other. The push blocks 32 slide in the slide groove 33 and drive the limiting post 4 to move in the circular groove 2 to compress the spring 31. One end of the limiting post 4 is disengaged from the handrail rocker arm 5, so that the handrail column 1 can be removed from the two handrail rocker arms 5 for replacement and maintenance. At the same time, the top of the two push blocks 32 is integrally machined with a protruding part to enhance the friction of the push block 32 movement. The telescopic rod 7 is located inside the spring 31 and prevents the spring 31 from bending and becoming unusable. An LED light strip 81 is installed at the handrail rocker arm 5. The LED light strip 81 can be turned on and off by the switch 82 to achieve the function of interior lighting.

[0034] It also includes a lighting element 8, which includes LED light strips 81 mounted on the surfaces of the two handrail rocker arms 5. The surfaces of the handrail rocker arms 5 are provided with switches 82 for controlling the LED light strips 81 to turn on. Both LED light strips 81 are electrically coupled to an external power source.

[0035] Specifically, an LED light strip 81 is installed at the armrest rocker arm 5. The LED light strip 81 can be turned on and off by the switch 82, which can provide interior lighting. Although the lights on the armrests are not mainly designed for reading or operating while driving, they can provide some lighting support in certain situations (such as when it is necessary to temporarily check items in the car or perform simple operations), making it more convenient for passengers to move around in the car. The lights on the armrests are usually beautifully designed and come in a variety of colors, and can be part of the interior ambient lighting, adding a warm and comfortable atmosphere to the interior space.

[0036] Mounting component 6 includes a mounting base 61 hinged to the top of the handrail rocker arm 5. The top of the mounting base 61 is integrally machined with an assembly plate 62, and the interior of the assembly plate 62 has holes for bolt insertion.

[0037] Furthermore, the mounting plate 62 has internal holes that facilitate bolt insertion, allowing the mounting plate 62 to be fixed to the roof of the vehicle. The mounting base 61 is hinged to the handrail rocker arm 5, giving the handrail a rotatable function.

[0038] The bottom of both armrest rocker arms 5 is integrally machined with hooks 11;

[0039] The main purpose of hook 11 is to facilitate drivers and passengers in hanging small items such as sunglasses, handbags, and shopping bags. If these items are not properly placed in the vehicle, they may cause clutter and even affect driving safety. During vehicle operation, especially when encountering sudden braking or bumpy roads, unsecured small items are prone to sliding or falling, which may pose a safety hazard to drivers and passengers. The design of hook 11 can effectively prevent this from happening and improve driving safety. With the design of hook 11, drivers and passengers can place small items more orderly and avoid the vehicle interior becoming cluttered due to random stacking of items. When using it, drivers and passengers should be careful not to hang excessively heavy items to avoid damaging hook 11 or affecting driving safety.

[0040] An arc-shaped plate 12 with an arc groove is fixedly installed on the surface of the handrail column 1. The arc-shaped plate 12 is set as an adhesive layer.

[0041] Specifically, the arc-shaped groove design increases the friction on the surface of the rubber layer, making it more stable for passengers to hold the handrail and less likely to slip. This is especially important for the elderly, children, and passengers with mobility impairments, as it can effectively reduce the risk of injury caused by the handrail slipping.

[0042] The handrail post 1 is made of engineering plastic, and both limiting posts 4 are made of solid metal.

[0043] Furthermore, the handrail post 1 is made of environmentally friendly engineering plastic, which has the advantages of being environmentally friendly and odorless, lightweight, high strength, strong corrosion resistance, and low manufacturing cost. Although the material is lightweight, engineering plastic has high strength and can withstand a certain amount of pressure. The plastic handrail is not easily corroded and can maintain a long service life. The limiting post 4 is solid metal and has strong rigidity.

[0044] When the plastic handrail needs to be removed, the two push blocks 32 at the top of the handrail column 1 are pushed closer to each other. The push blocks 32 slide in the slide groove 33 and drive the limiting post 4 to move in the circular groove 2 to compress the spring 31. One end of the limiting post 4 is disengaged from the handrail rocker arm 5, so that the handrail column 1 can be removed from the two handrail rocker arms 5 for replacement and maintenance. At the same time, the top of the two push blocks 32 is integrally machined with a protruding part to enhance the friction of the push block 32 movement. The telescopic rod 7 is located in the spring 31 to prevent the spring 31 from bending and becoming unusable. An LED light strip 81 is installed at the handrail rocker arm 5. The LED light strip 81 can be turned on and off by the switch 82 to achieve the function of interior lighting.

[0045] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
