Seat Armrest with Telescopic Cup Holder and Rotating Support

The problem

Traditional car armrests often feature static cup holders that occupy valuable surface area or require complex flipping mechanisms that can feel unstable. When the cup holder is not in use, it may protrude awkwardly, interfering with passenger comfort or limiting the usable space on the armrest top. Conversely, extending a cup holder outward usually requires manual effort without mechanical assistance, leading to uneven wear over time. Furthermore, rapid extension mechanisms can cause the assembly to shoot out unexpectedly if not properly dampened, creating a safety hazard or noise issue within the cabin. There is a need for an integrated solution that allows the cup holder to remain hidden and flush when stored, yet extend smoothly and rotate into a functional vertical position automatically when needed, all while maintaining structural integrity within the confined space of a standard seat armrest.

The solution

1. The system comprises an armrest shell (100) housing an internal armrest framework (200). This framework contains specific guide chutes (211, 212) that define the path of movement for the internal components.
2. A cup holder assembly (300) sits on a slide base box (310) equipped with chute clamping blocks. These blocks fit into the guide chutes, allowing the entire assembly to slide back and forth linearly along the length of the armrest.
3. Extension and retraction are powered by a driving piece (400), specifically a coil spring, which connects the slide base box to a fixed point on the framework, providing automatic return force.
4. To change the orientation of the cup holder, a rotating component (500) is mounted on the assembly. This includes a rotating shaft (320) attached to the cup holder (330). As the assembly slides, a guide pin (560) travels through a curved rotating chute (201) on the framework, forcing the shaft to rotate the cup holder from a horizontal (stored) state to a vertical (in-use) state.
5. Speed control is managed by a damping gear (360) on a sliding auxiliary seat plate (350) that meshes with a stationary rack (230) on the framework, ensuring smooth, gradual movement rather than a sudden pop.

Who it is for

• Automotive Interior Suppliers: Companies manufacturing complete seat assemblies or aftermarket armrest upgrades looking for compact, multi-functional designs that save space.
• OEM Vehicle Manufacturers: Brands seeking to differentiate their interior ergonomics with automated, refined cup holder mechanisms that integrate seamlessly into existing seat structures.
• Fleet & Commercial Vehicle Modifiers: Operators needing durable, self-returning mechanisms that withstand frequent use in taxis, ride-shares, or delivery vehicles where driver convenience is paramount.
• Aftermarket Accessory Makers: Businesses producing retrofit kits for older vehicles where factory armrests lack convenient cup holding options.

How it works

The main parts

Operating Steps

1. Activation: The user pushes the cup holder assembly outward. The slide base box moves along the first guide chute.
2. Rotation: As the assembly moves forward, the guide pin (part of the rotating component) follows the curve of the rotating chute on the framework. This forces the rotating shaft to turn, lifting the cup holder from a flat, horizontal position to a vertical, upright position.
3. Clamping: Once vertical, the torsion springs on the cup holder bars close inward to grip the beverage container securely.
4. Damped Retraction: When released, the driving spring pulls the assembly back. The damping gear engages with the rack, resisting the spring’s force to ensure the assembly returns slowly and quietly, preventing impact against the inner walls.
5. Locking: In certain positions, the lock rod engages with the locking member to hold the armrest steady during vehicle operation.

Applications

Passenger Vehicle Interiors

This design maximizes space efficiency in compact cars where armrest real estate is limited. By hiding the cup holder completely within the armrest volume when not in use, it provides a clean, uncluttered surface for resting arms or placing small items, improving perceived interior quality.

Ride-Sharing and Taxi Fleets

Drivers frequently handle drinks while navigating traffic. The automatic return and damped motion reduce distraction and noise. The robust locking mechanism ensures the cup holder stays secure during aggressive maneuvers or rough roads, maintaining stability for passengers’ beverages.

Luxury SUVs and Sedans

High-end interiors demand seamless integration. The rotating mechanism offers a sophisticated “magic trick” effect where the holder appears to rise organically from the armrest. The silent, smooth operation aligns with premium acoustic standards expected in luxury segments.

Heavy-Duty Trucks

For long-haul drivers, easy access to hydration is critical. The telescopic nature allows the holder to extend far enough for comfortable reach without requiring the driver to lean excessively. The durable spring-loaded design withstands daily heavy usage cycles better than simple friction-based hinges.

Where it is less suitable

• Minimalist Fixed Designs: Vehicles aiming for ultra-simple, non-moving interiors may find the complexity of the rotating chute and gears unnecessary cost.
• Extreme Vibration Environments: While locked, the intricate gear and pin system might be more susceptible to jamming in off-road conditions compared to simpler, solid-block cup holders.
• Low-Cost Economy Models: The precision required for the rotating chute and damping gear adds manufacturing complexity that may exceed budget constraints for entry-level vehicles.
