Abstract
Description
Technical Field
[0001] This application belongs to the field of mechanical design technology for daily necessities and vehicle / ship accessories, specifically relating to a gravity self-balancing anti-splashing cup holder based on a dual-axis universal joint mechanism. Background Technology
[0002] In scenarios such as desktop offices, RV travel, shipboard navigation, or wheelchair access, the stability of water cup placement is a common pain point. Current technologies typically employ the following solutions to prevent water cups from tipping over and spilling: 1. Suction cup anti-tipping cups, with silicone suction cups on the bottom to prevent tipping; 2. Deepened cup holders, such as those used in vehicles, often employ deepened holes to prevent tipping and spills; 3. Active electronic balance cup holders, using gyroscope sensors and servo motors for active attitude compensation. While these technologies can stabilize water cups, the following technical problems still exist:
[0003] (1) Suction cup anti-tipping cups require users to overcome a large suction force when taking the cup vertically upwards, resulting in a poor user experience, and the flatness of the surface on which they are placed is extremely important.
[0004] (2) Deepening the cup holder cannot solve the problem of liquid spilling out of the cup due to tilt and inertia when the vehicle is going up or down a slope or experiencing severe bumps.
[0005] (3) Active electronic balance cup holders are expensive, have an extremely complex structure, require an external power supply, and are not practical for everyday use.
[0006] Therefore, there is an urgent need for a new self-balancing water cup holder that is simple in structure, low in cost, requires no external energy, and can adapt to complex bumpy and tilted environments. Summary of the Invention
[0007] To address the aforementioned technical problems in the existing technology, the purpose of this invention is to provide a self-balancing water cup holder device that is simple in structure, low in cost, requires no external energy, and can adapt to complex bumpy and tilted environments. The technical solution is as follows:
[0008] A gravity-balanced, spill-proof cup holder based on a dual-axis universal joint mechanism includes a base, a cup holder, a connecting ring, a first set of pins, and a second set of pins. The connecting ring is located inside the outer fixed base. Support frames are respectively provided on both sides of the base. A hole is provided at the center of the upper side of the support frame. The first set of pins passes through the hole on the support frame and connects to the outer wall of the connecting ring. The connecting ring can swing freely around the first set of pins. The cup holder is located inside the connecting ring. The outer wall of the cup holder is connected to the connecting ring through the second set of pins. The cup holder can swing freely around the second set of pins.
[0009] Furthermore, both the first and second sets of pins are fitted with rubber damping washers or high-viscosity damping silicone grease at their connection points.
[0010] Furthermore, the cup holder is cylindrical or tray-shaped and used to hold the cup; the connecting ring is a rigid circular ring.
[0011] Furthermore, the base is a ring-shaped or U-shaped base, used to fix it to a desktop, vehicle body or other load-bearing surface.
[0012] Furthermore, the first set of pins and the second set of pins are orthogonal or perpendicular to each other in space, forming a two-degree-of-freedom pure mechanical universal joint mechanism.
[0013] Furthermore, both the first group of pins and the second group of pins contain two pins.
[0014] Furthermore, the first set of pins and the outer wall of the connecting ring are connected by a rotary hinge; the second set of pins and the outer wall of the cup holder are also connected by a rotary hinge.
[0015] Beneficial effects: (1) Simple structure and low cost. (2) It can achieve omnidirectional adaptive leveling of the cup body by relying solely on mechanical structure and gravity without external energy. (3) It can adapt to complex bumpy and tilting environments. Attached Figure Description

[0023] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.
[0024] like Figures 1a-1e As shown, the gravity self-balancing anti-splashing cup holder based on a dual-axis universal joint mechanism of the present invention includes a base 1, a cup holder 5, a connecting ring 2, a first set of pins 3 (X-axis) and a second set of pins 4 (Y-axis); wherein, each set of pins contains two pins.
[0025] The base 1 is a ring or U-shaped base with a support frame 6, used to fix it on a desktop, vehicle body or other load-bearing surface.
[0026] The connecting ring 2 is a rigid ring located inside the outer fixed base 1. The support frame 6 on the base 1 is respectively set on both sides of the base 1. The support frame 6 has a hole 7 at the center of the upper side. The first set of pins 3 (X-axis) passes through the hole 7 on the support frame 6 and is connected to the outer wall of the connecting ring 2 by a rotational hinge, so that the connecting ring 2 can swing freely around the first set of pins 3 (X-axis).
[0027] The cup holder 5 is located inside the connecting ring 2 and is cylindrical or tray-shaped, used to hold a cup. The outer wall of the cup holder 5 is connected to the connecting ring 2 by a second set of pins 4 (Y-axis) through a rotary hinge, so that the inner cup holder 5 can swing freely around the second set of pins 4 (Y-axis) through a rotary hinge.
[0028] The first set of pins 3 (X-axis) and the second set of pins 4 (Y-axis) are perpendicular or 90 degrees apart in space, thus forming a two-degree-of-freedom pure mechanical universal joint (Gimbal) mechanism.
[0029] The rotational hinge point of the inner cup holder 5 is located slightly above the geometric center of the cup holder 5; this ensures that after placing a cup and liquid, the overall center of gravity of the entire moving assembly is always directly below the plane containing the X and Y axes.
[0030] At the connection between the first set of pins 3 (X-axis) and the second set of pins 4 (Y-axis), rubber damping washers or high-viscosity damping silicone grease are installed. When the environment experiences severe vibration, the damping mechanism can effectively absorb the impact energy and prevent the water cup holder 5 from undergoing continuous pendulum-like reciprocating oscillations, allowing it to quickly decay and stabilize in a vertical state.
[0031] Working principle
[0032] like Figure 2As shown, regardless of the angle at which the outer fixed base 1 tilts due to external environment (such as table tilt or vehicle / ship bumps), the first set of pins 3 (X-axis) and the second set of pins 4 (Y-axis) provide two orthogonal degrees of freedom, and the center of gravity of the inner cup holder 5 is always suspended below the rotation axis. Under the action of gravity (similar to the pendulum effect), the inner cup holder 5 will automatically offset the tilt angle of the base 1 and always remain absolutely perpendicular to the horizontal plane, thus completely solving the problem of liquid spillage.
