Description

Technical Field

[0001] This utility model relates to the field of outdoor street lights, specifically to a spinning-type adaptive outdoor lamp head connection system. Background Technology

[0002] Currently, in traditional outdoor street lighting systems, the connection between the lamp head and the pole presents numerous problems when designed using the same principles as household light bulbs due to the unique nature of the lamps. These problems include: insufficient wind resistance: traditional lamp heads are prone to swaying or deflection in strong winds, leading to poor lighting performance and potentially damaging the lamp head or connecting components. Inflexible lamp head adjustment: traditional lamp head angle adjustments typically require manual operation, resulting in low precision and susceptibility to imbalance under external forces. Low maintenance efficiency: the installation and removal of traditional lamp heads are complex, usually requiring specialized tools and personnel, increasing maintenance costs and time. These issues highlight the immaturity of outdoor street lighting connection systems. As a crucial component of urban infrastructure, project managers must conduct daily patrols and inspections. Improving product lifespan, reducing maintenance costs, and enhancing overall maintenance efficiency would significantly enhance the competitiveness of companies operating in this field.

[0003] To address the aforementioned issues, we have made a series of improvements. Utility Model Content

[0018] The present invention will be further described below with reference to specific embodiments. It should be understood that the following embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention.

[0019] Example 1

[0020] Figure 1This is a schematic diagram of the structure of this utility model. Figure 2 This is a structural schematic diagram of another aspect of the present invention.

[0021] like Figure 1-2 As shown, a spin-forming adaptive outdoor lamp head connection system includes: a base connecting flange 100, a ball-joint damping composite joint 200, a self-balancing drive module 300, a guide ring 400, a quick-connect interface 500, and an intelligent control system 600. The base connecting flange 100 is connected to the top of the lamp post 1 by pre-tightening bolts. The ball-joint damping composite joint 200 is nested inside the base connecting flange 100. The self-balancing drive module 300 extends laterally through the side wall of the base connecting flange 100 and is connected to the ball-joint damping composite joint 200. The guide ring 400 covers the outside of the ball-joint damping composite joint 200. The quick-connect interface 500 is connected to the top of the ball-joint damping composite joint 200 and is connected to the lamp head 2. The intelligent control system 600 is connected to the internal cavity of the base connecting flange 100.

[0022] The ball joint damping composite joint 200 includes: a stainless steel ball joint body 210, a fluid damping cavity 220, a phase change constraint layer 230, and a sealing end cap 240. The stainless steel ball joint body 210 is connected to the base connecting flange 100. A 5mm gap layer is provided on the outer surface of the fluid damping cavity 220 and the stainless steel ball joint body 210. The phase change constraint layer 230 is provided on the outer wall of the fluid damping cavity 220. The sealing end cap 240 is fixed to the top of the stainless steel ball joint body 210.

[0023] The self-balancing drive module 300 includes: a servo motor 310, a harmonic reducer 320, a magnetic coupling drive shaft 330, and an angle encoder 340. The output shaft of the servo motor 310 is connected to the input end of the harmonic reducer 320. The magnetic coupling drive shaft 330 passes through the side wall of the base connecting flange 100 and is connected to the harmonic reducer 320. The magnetic coupling drive shaft 330 is also connected to the stainless steel ball joint body 210. The angle encoder 340 is embedded at the end of the magnetic coupling drive shaft 330.

[0024] The quick-connect interface 500 includes: a three-contact electrical module 510, a bayonet-type buckle 520, and a tapered pin 530. The tapered pin 530 is connected to the lamp holder 2 through the bayonet-type buckle 520, and the tapered pin 530 is connected to the stainless steel ball joint body 210. The three-contact electrical module 510 connects the lamp holder 2 to the base connecting flange 100.

[0025] The base connecting flange 100 of this utility model is fixedly connected to the top of the lamp post 1 by high-strength bolts, providing the main load-bearing structure. It integrates a power supply line, which supplies power to the lamp head 2 via a three-contact electrical module 510. The lateral extension compartment houses the self-balancing drive module 300.

[0026] The stainless steel ball joint body 210 and the base connecting flange 100 are interference-fitted. A fluid damping cavity 220 encloses the stainless steel ball joint body 210 and is filled with a non-Newtonian fluid to provide dynamic stiffness adjustment. The phase change constraint layer 230 is welded to the fluid damping cavity 220 to achieve temperature-responsive stiffness compensation. The sealing end cap 240 uses a double O-ring seal to prevent environmental corrosion. The servo motor 310 receives commands from the intelligent control system 600 and outputs adjustable torque.

[0027] The harmonic reducer 320 controls speed and precision, the magnetic coupling drive shaft 330 transmits torque to the stainless steel ball joint body 210 without contact, and the angle encoder 340 provides real-time feedback of lamp head posture data. The guide ring 400 serves as the external slide rail structure of the stainless steel ball joint body 210. The three-contact electrical module 510 uses silver-graphite contacts, enabling optical isolation of the signal lines via fiber optics. The bayonet-type buckle 520 employs a 7° inclined locking structure, locking is achieved by rotating 30° with one hand (tensile strength ≥800N), and the built-in disc spring assembly provides continuous clamping force. These are products directly purchased from a German brand. The intelligent control system 600 collects real-time data on wind speed (0-40m / s), tilt angle (±0.1°), and temperature (-40℃~85℃), dynamically adjusting joint stiffness and lamp head angle through a PID algorithm.

[0028] Compared with traditional technologies, this invention improves wind resistance through the dynamic response of a ball-joint damping composite joint; the self-balancing drive module enables automatic adjustment and reset of the lamp head, enhancing the flexibility and precision of adjustment; and the quick-install interface design allows for rapid assembly and disassembly of the lamp head, significantly improving maintenance efficiency. Its specific principle is as follows: When the wind speed is >25m / s: the viscosity of the shear-thickening fluid within the fluid damping chamber 220 increases by 10%. 4 The phase transformation constraint layer 230 switches to the austenitic state (elastic modulus 28 GPa) at low temperature, and forms a three-level wind-resistant barrier through fluid damping energy dissipation → phase transformation layer rigid support → magnetic coupling transmission buffer.

[0029] Self-balancing principle: Angle encoder 340 detects the deflection angle → Intelligent control system 600 calculates the compensation amount → Servo motor 310 drives harmonic reducer 320 → Magnetic coupling transmission shaft 330 drives ball joint for fine adjustment → Lamp head 2 resets to the set angle.

[0030] Quick Installation: Insert the lamp holder 2 into the guide ring 400 via the tapered pin 530 → rotate the bayonet-type buckle 520 to the locking position, then the three-contact electrical module 510 automatically conducts (0.5s delay to prevent arcing). Quick Removal: Rotate the bayonet-type buckle 45° in the opposite direction → spring-assisted ejection of the lamp holder 2. The electrical connection then disconnects before the mechanical separation.

[0031] The test item standard requires the measured result to exceed the standard by a certain margin.

[0032] Vibration test IEC 60068-2-6 20g@2000Hz meets the standard

[0033] Salt spray corrosion test GB / T 10125: No corrosion after 3000h, exceeding the national standard by 3 times.

[0034] High and low temperature cycling GB / T 2423.22 - Normal operation from 40℃ to 85℃

[0035] The wind fatigue resistance EN 40-3-3 project, which withstands 5 million cycles without plastic deformation, has been tested on a small scale. Statistical analysis shows that its implementation benefits include reduced operation and maintenance costs: reduced frequency of high-altitude operations (annual maintenance costs reduced by 65%), increased spare parts commonality rate to 95%; optimized energy efficiency, with adaptive dimming reducing ineffective lighting (energy savings of over 30%), and magnetic coupling transmission efficiency >98% (traditional gearboxes <90%); improved compliance, meeting the latest wind resistance requirements of GB / T 7000.1-2015, and obtaining CE and UL1598 dual certifications.

[0036] The specific embodiments of this utility model have been described above, but this utility model is not limited thereto. Various changes can be made to this utility model as long as they do not depart from its spirit.
