Description

Technical Field

[0001] This utility model relates to the field of lighting equipment technology, specifically a ceramic table lamp with a buffer and shock absorption structure. Background Technology

[0002] Currently, desk lamps are widely used as common lighting devices in scenarios such as studying, working, and precision tasks. Most existing desk lamps use a metal or plastic base structure, with the lamp head supported by a fixed rod or folding arm to achieve adjustable lighting angle. However, under long-term use or in environments with external vibrations, these desk lamps generally suffer from the following technical problems:

[0003] First, the base structure of traditional desk lamps has poor stability. Common bases are mostly made of a single piece of cast iron or plastic, relying solely on weight for stability. When the user adjusts the lamp head angle or external vibrations occur (such as table vibrations or mechanical resonance), the lamp is prone to wobbling, displacement, or even tipping over, affecting safety and lighting stability. While some products use rubber pads or elastic layers for cushioning, the shock absorption effect is limited and cannot effectively disperse impact force. Existing desk lamps generally lack effective cushioning and shock absorption designs. In current technology, the base and support arm are usually connected by a rigid structure, which cannot absorb the instantaneous stress caused by external impacts, causing vibrations to be directly transmitted to the lamp head, leading to light source wobbling or loosening of electronic components. Furthermore, some shock absorption solutions using springs or flexible rubber layers only provide cushioning in one direction, failing to achieve multi-axial shock absorption and energy dispersion, resulting in a shorter structural lifespan.

[0004] In view of this, we have studied and improved upon the existing problems to provide a ceramic table lamp with a buffer and shock absorption structure to solve the current issues. The aim of this technology is to solve the problems and improve its practical value. Utility Model Content

[0005] This utility model aims to solve one of the technical problems existing in the prior art or related technologies.

[0006] Therefore, the technical solution adopted by this utility model is as follows: a ceramic table lamp with a buffer and shock absorption structure, including a lamp head, an adjustable support arm, and a shock-absorbing base. By introducing a planar shock absorber, an elastic connecting piece, and a counterweight structure inside the base, the lamp body absorbs vibrations and releases energy in both vertical and horizontal directions, so that the overall structure has the functions of shock absorption, posture balance, and stable support.

[0007] In a preferred embodiment, the lamp head is fixedly mounted on one end of the adjustable support arm, and the other end of the adjustable support arm is movably mounted on the surface of the shock-absorbing base. The shock-absorbing base includes a counterweight, a sliding plate, and a planar shock absorber fixed to the inner side of the sliding plate. The bottom surface of the counterweight slides against the upper surface of the sliding plate, and a pendulum is fixedly mounted on the surface of the sliding plate. The planar shock absorber includes a ring, a fixed foot, and several elastic connecting pieces. The pendulum is fixedly connected to the inner side of the ring, and the several elastic connecting pieces are arranged in an L-shape, with their two ends fixedly connected to the surfaces of the ring and the fixed foot, respectively, to achieve buffering and shock absorption of the sliding plate relative to the counterweight.

[0008] Specifically, under the action of external force, the structure can absorb impact energy through the multi-directional elastic deformation of the planar shock absorber and return to its original position after release, achieving multi-axial flexible support and significantly improving the overall shock resistance and stability performance of the desk lamp.

[0009] In a preferred example, the counterweight base is a monolithic ceramic structure filled with metal counterweight blocks to improve center of gravity stability and seismic performance.

[0010] Specifically, the ceramic shell provides excellent electrical insulation and heat resistance, while the metal counterweight forms a bottom center of gravity structure, effectively preventing the lamp from tipping over due to external forces or angle adjustments, so that the table lamp can maintain balance and stability in operation and vibration environments.

[0011] In a preferred example, the slide block is made of high-strength aluminum alloy with an anodized surface to improve wear resistance and reduce sliding friction resistance.

[0012] Specifically, the sliding plate seat achieves flexible support through sliding contact, and its metal-reinforced structure makes the sliding process smooth and reliable, ensuring the controllability of friction during vibration absorption and reset, and extending the overall service life.

[0013] In a preferred example, the planar shock absorber is installed at the center of the counterweight base cavity and fixed to the inside of the counterweight base by screws to achieve elastic buffering in the vertical direction.

[0014] Specifically, this fixing method ensures a stable force transmission path between the planar shock absorber and the base, and can efficiently absorb energy and block the impact force transmitted to the upper structure during vertical vibration or impact, thereby improving the overall vibration resistance of the lamp.

[0015] In a preferred example, the planar shock absorber is a one-piece molded structure made of a high-molecular elastic material, which has good deformation recovery capability and is used to absorb vibration impact and prevent energy from being transferred to the upper structure.

[0016] Specifically, this elastic material has excellent deformation recovery rate and damping performance, and can maintain a stable buffering effect even in multiple impact cycles, significantly reducing structural fatigue and wear.

[0017] In a preferred example, the elastic connecting piece is made of stainless steel spring sheet or polymer elastic material sheet with a thickness of 0.5 to 1.2 mm, used to provide cushioning force when compressed and return to its original position after release.

[0018] Specifically, the elastic connecting piece forms an energy absorption circuit through deformation and recovery, which can effectively suppress vibration propagation and ensure that the slide plate seat has independent shock absorption function in both the horizontal and vertical directions.

[0019] In a preferred example, the adjustable arm is a double-link structure with a torsion spring installed at its joint to achieve self-balancing positioning after the lamp head angle is adjusted.

[0020] Specifically, the torsion spring provides the opposite torque after the lamp head angle is adjusted, so that the lamp head can remain stable at any angle, preventing angle deviation due to inertia or gravity swing, and achieving a balance between balanced support and operational flexibility.

[0021] The beneficial effects achieved by this utility model are as follows:

[0022] 1. In this utility model, through the coordinated design of the planar shock absorber, the elastic connecting piece and the ceramic counterweight structure, the desk lamp can automatically absorb and disperse stress when subjected to external impact or table vibration, which significantly improves the structural stability and safety of use.

[0023] 2. In this utility model, the double-link torsion balance structure of the adjustable support arm is combined with the multi-layer shock-absorbing base to keep the lamp head in a stable position after the angle is adjusted, avoiding shaking and displacement, and achieving a high-precision and low-vibration lighting effect.

[0032] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0033] It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this invention.

[0034] The following describes, with reference to the accompanying drawings, some embodiments of the present invention, providing a ceramic table lamp with a buffer and shock absorption structure.

[0035] Combination Figures 1-5 As shown, this utility model provides a ceramic table lamp with a buffer and shock absorption structure, including main components such as a lamp head 100, an adjustable support arm 200, and a shock-absorbing base 300. This structure, through a composite design of a planar shock absorber 330 and a counterweight system at the bottom of the lamp, achieves shock absorption, center of gravity stability, and multi-angle posture maintenance during use.

[0036] In this embodiment, the lamp head 100 is mounted on the upper part of the shock-absorbing base 300 via an adjustable support arm 200. The adjustable support arm 200 is a double-link structure, with its upper and lower links connected by a pivot hinge. A torsion spring is installed at the joint to provide a rebound torque. When the lamp head 100 is adjusted in angle, the torque generated by the torsion spring balances the weight of the lamp head 100, allowing the lamp head 100 to remain stably suspended at any angle, thereby achieving multi-angle, steplessly adjustable lighting functionality.

[0037] The shock-absorbing base 300 is a key structural component of this invention, used to buffer and stabilize the lamp body. The shock-absorbing base 300 includes a counterweight 310, a sliding plate base 320, and a planar shock absorber 330 fixed inside the sliding plate base 320. The counterweight 310, located at the bottom, is an integral ceramic structure filled with metal counterweights to increase the bottom center of gravity and prevent the lamp body from tipping over. The bottom surface of the counterweight 310 slides against the upper surface of the sliding plate base 320, allowing for slight relative displacement between them, thus providing an energy absorption space under external impact or vibration.

[0038] like Figures 2 to 4As shown, the upper part of the slide plate seat 320 is provided with a swing core 321, which is fixedly sleeved inside the ring sleeve 331 of the planar shock absorber 330. The ring sleeve 331 is a circular elastic structure, and its outer side is connected to the fixed feet 332 of the planar shock absorber 330 through several L-shaped elastic connecting pieces 333, forming an elastic suspension connection system. The elastic connecting pieces 333 are made of stainless steel spring sheets or polymer elastomers, with a thickness of 0.5 to 1.2 mm, and can undergo elastic deformation under force to absorb vibration energy. The fixed feet 332 are symmetrically arranged on both sides of the planar shock absorber 330 to fix the connecting ring sleeve 331 and limit its radial displacement, ensuring the overall balance of the elastic system.

[0039] When external vibration or impact is applied to the desk lamp, the pendulum 321 undergoes a slight displacement along with the slide base 320, causing the ring 331 to deform accordingly. This causes the elastic connecting piece 333 to bend and deform, thereby absorbing part of the impact force. The vibration energy is dispersed and dissipated by the elastic connecting piece 333 and the polymer damping layer, achieving multi-directional buffering. After the vibration ends, the elastic connecting piece 333 returns to its original shape due to its elasticity, and the slide base 320 returns to its initial position under the action of elastic restoring force, achieving automatic reset and stable support.

[0040] In another preferred embodiment, the planar shock absorber 330 is made of a monolithically molded polymer elastomer material and has several metal skeleton reinforcing ribs embedded inside to improve structural strength and durability. This shock absorber provides multi-axial buffering when subjected to forces in the vertical, horizontal, or torsional directions, ensuring the overall shock resistance of the lamp body.

[0041] Furthermore, the counterweight base 310 has a ceramic shell structure, with a removable metal counterweight block inside, which is sealed and fixed by a bottom cover plate, facilitating later maintenance and center of gravity adjustment. The ceramic material has excellent insulation and heat resistance properties, which can effectively block the heat of the lamp holder 100 from being conducted to the bottom, while enhancing the overall texture and decoration.

[0042] In another preferred embodiment, the slide block 320 is made of high-strength aluminum alloy and its surface is anodized to enhance wear resistance and reduce the coefficient of sliding friction. A controllable friction interface is formed between the slide block 320 and the counterweight 310 by coating a lubricating layer, which provides smooth sliding during vibration and prevents instability caused by eccentric sliding.

[0043] During use, when the user touches or adjusts the lamp head 100, the torsion spring can automatically compensate for the change in force, so that the lamp head 100 maintains a balanced state at the new angle position; at the same time, the flat shock absorber 330 at the bottom absorbs the instantaneous force transmitted to the bottom of the lamp, realizing the buffering and shock absorption of the overall structure, and preventing the vibration from being transmitted upward along the support arm, causing the lamp head to shake or tip over.

[0044] Working principle and usage process of this utility model:

[0045] The ceramic table lamp with a buffer and shock absorption structure provided by this utility model has the core technology of realizing dynamic buffering and steady-state reset of the lamp body when it is subjected to external impact or displacement by setting a composite base structure consisting of a counterweight 310, a sliding plate 320 and a planar shock absorber 330; at the same time, the adjustable support arm 200 and the lamp head 100 are coordinated to ensure that the lighting posture is flexible and controllable.

[0046] When the desk lamp is in normal use, the shock-absorbing base 300 provides stable support for the entire structure. The counterweight base 310 serves as the basic load-bearing component; its ceramic body provides insulation and high stability, while the internal metal counterweights enhance the overall center of gravity, preventing tipping during external forces or operation.

[0047] The sliding base 320 and the counterweight base 310 are in a sliding contact relationship. The sliding base 320 is connected to the planar shock absorber 330 through the pendulum core 321. The pendulum core 321 is fixedly sleeved inside the ring 331 of the planar shock absorber 330. The ring 331 is connected to the fixed foot 332 through several L-shaped elastic connecting pieces 333. When external impact or vibration is applied to the desk lamp (such as hand touch, table vibration, or impact caused by angle adjustment), the sliding base 320 will have a slight displacement relative to the counterweight base 310. At this time, the elastic connecting pieces 333 deform and absorb part of the kinetic energy, realizing multi-directional buffering and preventing the vibration from being directly transmitted to the upper adjustable support arm 200 and lamp head 100, thereby effectively protecting the lamp body structure.

[0048] After the impact, the elastic connecting piece 333 recovers its original shape due to the resilience of its material, driving the sliding plate 320 and the upper lamp body back to their original equilibrium position, thus achieving an automatic reset function. If the lamp body is subjected to continuous external force (such as during angle adjustment), the planar shock absorber 330 provides dynamic support through its overall polymer elastomer structure, keeping the lamp body flexible and stable under different postures and avoiding swaying and structural fatigue.

[0049] Meanwhile, the adjustable arm 200 adopts a double-link mechanism design with torsion springs at the joints, which can automatically achieve torque balance after the lamp head 100 is adjusted. When the user raises or lowers the lamp head 100, the torsion spring generates a corresponding rebound force, which balances with the weight of the lamp head, thereby achieving stable hovering of the lamp head at any angle without attitude deviation due to gravity or vibration.
