Description

Technical Field

[0001] This invention relates to the field of lighting technology, specifically to a contour-following flame lamp. Background Technology

[0002] As a decorative and atmosphere-creating device, the core of a flame-shaped lamp lies in simulating the dynamic effects of a real flame's flickering and dancing through mechanical or optical means to enhance visual appeal. In existing technologies, common methods for achieving flame-shaped movement include using multiple motors to drive the lamp post in different directions, or employing complex multi-link mechanisms to synthesize irregular motion trajectories. These solutions can simulate the dynamics of a flame to a certain extent, reflecting the continuous exploration and pursuit of flame shape simulation.

[0003] However, in the pursuit of more dynamic and realistic effects, some existing technical solutions still have room for optimization. For example, solutions relying on multiple independent drive sources may lead to complex structures, higher costs, and greater difficulty in control coordination, making it difficult to guarantee the synchronization and consistency of moving parts over long-term operation. While some purely mechanical linkage mechanisms may simplify the drive, the synthesized motion trajectories sometimes appear somewhat stiff in terms of smoothness and naturalness, making it difficult to accurately simulate the soft, continuous, and rhythmic fluctuations of flames. Visually, this may produce a sense of abruptness or an overly regular "mechanical feel," thus affecting the realism of the simulation. In addition, the compactness, reliability, and ease of production and assembly are also factors that need to be comprehensively considered in practical applications.

[0004] Therefore, since it does not meet the existing needs, we have proposed a shape-imitating flame lamp. Summary of the Invention

[0005] This invention provides a contour-following flame lamp. This solution achieves absolute synchronization and reverse symmetry of the movement of two lamps through the synergistic effect of symmetrical gear-rack transmission and sinusoidal wave groove, laying the foundation for a regular visual rhythm. The sinusoidal wave groove transforms the continuous and smooth lateral movement into longitudinal undulations, effectively simulating the gentle and natural rhythm of the flame's circulation and eliminating the feeling of movement jerking. The entire drive and transmission mechanism is highly integrated inside the support and positioning base, resulting in a compact structure and reliable transmission, significantly improving product stability and assembly efficiency. Ultimately, elegant and consistent contour-following dynamics can be obtained simply through the forward and reverse control of the motor, creating a rich visual experience with simple mechanics and solving the problems mentioned in the background technology.

[0006] The present invention provides the following technical solution: a contoured flame lamp, including a support base and a positioning base fixed to its bottom, the top of the support base is provided with symmetrical limiting grooves, the support base is provided with a first receiving cavity, a rotating gear is installed in the center of the first receiving cavity, and the positioning base is provided with an embedded motor for driving the rotating gear to rotate. The rotating gear has a first rack and a second rack symmetrically meshing on both sides. The upper ends of the first rack and the second rack are both fixedly connected to a mounting base. The lamp component is longitudinally slidably arranged in the mounting base, and the upper end of the lamp component is limited and slidably arranged in the limiting groove. The lamp component is composed of a lamp rod body and a lamp base that can slide relative to each other.

[0007] As an alternative solution for the contour-following flame lamp described in this invention, the limiting groove is a sine wave structure.

[0008] As an alternative solution for the contour flame lamp described in this invention, the lamp component and the mounting base are longitudinally slidably connected by a ball bearing structure.

[0009] As an alternative solution for the contour-following flame lamp described in this invention, the first rack and the second rack are arranged symmetrically with respect to the center of the rotating gear.

[0010] As an alternative solution for the contour-following flame lamp described in this invention, the output end of the embedded motor is fixedly connected to the rotating gear.

[0011] As an alternative solution for the contour flame lamp described in this invention, the mounting base has a movable sliding groove inside.

[0012] As an alternative solution for the contour-following flame lamp described in this invention, a third rack is fixedly installed on the inner wall of the movable slide.

[0013] As an alternative solution for the contour flame lamp described in this invention, the base of the lamp is equipped with a movable gear via a rotating rod, and the movable gear meshes with the third rack.

[0014] As an alternative solution for the contour flame lamp described in this invention, the lamp base is provided with a pressing protrusion on the top, and a second receiving cavity is provided inside the lamp rod, with the pressing protrusion located inside the second receiving cavity.

[0015] As an alternative embodiment of the conformal flame lamp described in this invention, a compression connecting rod is fixedly installed on the top of the second receiving cavity, the compression protrusion has a symmetrical inclined surface, and the lamp rod body and the lamp base are elastically connected by a return spring and a connecting slide rod.

[0016] The present invention has the following beneficial effects: 1. This contour-following flame lamp achieves a highly realistic flame dynamic effect through the coordinated design of gear-rack and sine wave groove. The symmetrical gear-rack transmission ensures absolute synchronization and opposite directions of movement for both lamps, creating a regular and harmonious visual rhythm. Furthermore, the sine wave groove, as the core guide, smoothly and continuously transforms lateral linear motion into longitudinal undulating motion, eliminating any sense of movement abruptness and effectively simulating the gentle, cyclical natural rhythm of a flickering flame. Finally, the entire drive, transmission, and trajectory synthesis mechanism is highly integrated within the support and positioning base, resulting in a compact structure, simple appearance, and reliable power transmission path. This significantly improves product stability, lifespan, and production assembly efficiency. Ultimately, complex, elegant, and consistent contour-following dynamics can be achieved simply through the forward and reverse control of the motor, creating a rich visual experience with minimalist mechanics.

[0017] 2. This shaped flame lamp, by adding a transmission chain consisting of a gear-rack pair and a cam-spring mechanism, generates an independent, periodic axial additional pulsation while the lamp is swinging on its base. After the two movements are combined, the final movement trajectory of the lamp top is superimposed with controlled, rhythmic random jumping and trembling on a smooth, undulating wave-like basis. Its dynamic complexity and unpredictability are significantly enhanced, thereby greatly improving the realism and visual vitality of the flame simulation. Attached Figure Description

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Example 1, please refer to Figures 1-6 To achieve a more dynamic and realistic viewing effect for the contour flame lamp, this solution incorporates targeted design in mechanical transmission and motion trajectory synthesis. The special structure limiting slide groove 101 symmetrically opened on the top of the support 1 is the core guiding component of the entire contour movement. The positioning base 2 is fixedly installed at its bottom, and an embedded motor is set inside the positioning base 2. The first receiving cavity 102 opened inside the support 1 constitutes the encapsulation space of the transmission system. The rotating gear 103 installed at its center is directly fixedly connected to the output end of the embedded motor. This setting allows the power to directly drive the rotating gear 103 to rotate once the user starts the motor.

[0022] The key lies in the transmission design of the gear and rack. The rotating gear 103 is symmetrically arranged with a first rack 104 and a second rack 105 on both sides. The three are always in a meshing state. The ingenuity of this symmetrical layout is that when the rotating gear 103 rotates, it can force the two racks to make completely synchronous and opposite lateral linear movements. This movement in opposite directions lays the mechanical foundation for simulating the symmetrical dynamics of the flame swaying left and right. In order to further transform the linear motion into complex contouring motion, the mounting base 106 is firmly installed on the upper surface of the first rack 104 and the second rack 105. The lamp component 107 is limited in a longitudinally sliding manner inside the mounting base 106, and the upper end of the lamp component 107 is limited and slidably set inside the limiting groove 101.

[0023] In other words, when the motor drives the rotating gear 103 to rotate in both directions, this rotation is converted into the two lamp components 107 moving laterally towards or away from each other inside the first receiving cavity 102. The reason why the flame-like undulating effect can be produced is that the limiting slide 101 is designed as a sine wave structure. When the upper end of the lamp component 107 is forced to move along this wave-shaped slide, the lateral displacement is continuously converted into longitudinal displacement by the curved shape of the slide. Therefore, while the lamp component 107 moves laterally with the mounting base 106, it will also make a continuous and smooth longitudinal reciprocating motion relative to the mounting base 106 under the forced guidance of the slide. After the two movements are combined, the top of the lamp component 107 draws a sine wave trajectory.

[0024] This series of settings brings multiple benefits: First, the rack and pinion transmission ensures absolute synchronization and reverse symmetry in the movement of the two lamp components 107, which is the foundation for achieving a regular and harmonious visual rhythm. Second, the use of a sinusoidal groove as a trajectory constraint allows the lifting speed of the lamp component 107 to change continuously without any jerking, effectively simulating the soft, cyclical natural rhythm of a flickering flame, far superior to simple straight or broken lines. Finally, the entire mechanism highly integrates the drive, transmission, and trajectory synthesis within the support 1 and positioning base 2, resulting in a compact structure, simple appearance, and a clear and reliable power transmission path. This facilitates production and assembly while also improving the overall stability and service life of the equipment. Through simple forward and reverse control of the motor, complex, elegant, and highly consistent contoured flame dynamics can be obtained, achieving the design goal of creating a rich visual experience with simple mechanics.

[0025] Example 2: This example aims to further enhance the visual appeal of the shaped flame lamp. It is an improvement upon Example 1. For details, please refer to [link / reference]. Figures 1-6 In this design, a movable slide groove 110 is provided inside the mounting base 106. A third rack 109 is fixedly installed on the inner wall of the movable slide groove 110. Meanwhile, the lamp component 107 is designed as a split structure, consisting of a lamp rod 1071 and a lamp base 1072. The two are elastically connected by a return spring 112 and are guided to slide relative to each other by a connecting slide rod 115. The key is that the lamp base 1072 is limited and slidably set in the movable slide groove 110 by a ball bearing structure. This design ensures that the lamp base 1072 can slide smoothly longitudinally along the mounting base 106 and rotate freely around its own axis. A movable gear 108 is installed at the bottom of the lamp base 1072 by a rotating rod. The movable gear 108 is always engaged with the fixed third rack 109.

[0026] In other words, when the lamp pole 1071 moves under the limiting action of the limiting slide groove 101, the lamp base 1072 will also slide longitudinally within the moving slide groove 110 opened in the mounting base 106. It should be noted that the lamp pole 1071 is only restricted within the limiting slide groove 101, so that when the lamp component 107 moves, the lamp pole 1071 can be restricted by the contact of the limiting slide groove 101. In fact, there is no substantial connection between the lamp pole 1071 and the limiting slide groove 101. This setting is also to avoid the lamp pole 1071 from being connected later. When 71 moves up and down, motion interference will occur. During this process, the moving gear 108 will also mesh and rotate with the third rack 109, thereby driving the lamp base 1072 to rotate around the axis. Since the pressing protrusion 114 is installed on the top of the lamp base 1072, the pressing protrusion 114 will also rotate synchronously. It should be noted that the pressing protrusion 114 is designed with a special shape with symmetrical inclined surfaces on both sides. It is accommodated in the second receiving cavity 111 inside the lamp pole 1071, and the pressing connecting rod 113 is fixedly installed on the top of the second receiving cavity 111.

[0027] As the pressing protrusion 114 rotates, its two inclined surfaces will periodically and smoothly push against or release the pressing connecting rod 113. When the inclined surfaces push against, the lamp rod 1071 will overcome the elastic force of the return spring 112 and obtain a smooth upward displacement relative to the lamp base 1072. When the inclined surfaces turn away, the elastic restoring force of the return spring 112 will stably pull back the lamp rod 1071 and reset it. In this way, the rotation of the lamp base 1072 is continuously converted into additional reciprocating pulsations of the lamp rod 1071 in the longitudinal direction.

[0028] With the above-mentioned setup, not only can the gear-rack pair automatically convert to rotational motion, but the cam-spring mechanism can also convert it to axial pulsation. Finally, this pulsation is combined with the basic wave-shaped oscillation guided by the sine wave-shaped limiting groove 101 as described in Embodiment 1. As a result, the final movement trajectory of the top of the lamp pole 1071 is no longer a regular sine wave, but rather a rhythmic random jump with frequency and amplitude controlled by mechanical parameters superimposed on a smooth undulating wave base. Its dynamics are closer to the unpredictable vitality of a real flame flickering.

[0030] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
