Description

Technical Field

[0001] This invention relates to the field of street light technology, specifically to an LED smart street light head connection assembly. Background Technology

[0002] Streetlights are lights installed on roads to provide necessary visibility for vehicles and pedestrians at night. Typically, a streetlight consists of a pole and a lamp head. The lower end of the pole is connected to the ground, and the lamp head is connected to the upper end of the pole.

[0003] For example, Chinese patent CN 213395242U, entitled "An Energy-Saving Streetlight Head with Waterproof and Vapor-Resistant Properties," includes a lamp housing, a bulb, and a lamp shade. The lamp shade and lamp housing together form a lamp cavity. A receiving groove is provided on the side wall of the lamp shade facing the lamp housing, and this groove connects to the lamp cavity. A desiccant is placed inside the receiving groove. When the bulb reaches the end of its service life, the lamp shade is opened, the old bulb is removed, and a new bulb is installed. The desiccant is placed in the receiving groove of the lamp shade, and then the lamp shade is installed at the bottom of the lamp housing to complete the bulb replacement. If humid air enters the lamp cavity during the replacement process, the desiccant absorbs the moisture inside the lamp cavity, effectively reducing the generation of water vapor and ensuring the lighting effect of the streetlight.

[0004] While the waterproof and energy-saving street light head described in the aforementioned patent is practical and convenient, it also has its shortcomings. The conventional installation process for the street light head involves first installing the bulb onto the lamp holder and then installing the lamp cover onto the lamp housing. This installation process is complex, and the bulb may fall and be damaged during disassembly. Summary of the Invention

[0005] The purpose of this invention is to provide an LED smart street light head connection assembly to overcome the shortcomings of the prior art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: The LED smart street light head connection assembly includes a lamp housing, a lamp holder disposed inside the lamp housing, a bulb, a lamp cover, a first transmission component, and a second transmission component. The bulb is movably connected inside the lamp cover, and the bulb and the lamp holder are detachably connected. The lamp cover is rotatably engaged with the lamp housing. During the rotation of the lamp cover relative to the lamp housing, it sequentially has a first stroke and a second stroke. The first transmission component receives the drive of the first stroke during the rotation of the lamp cover relative to the lamp housing to move the bulb downward. The second transmission component receives the drive of the second stroke during the rotation of the lamp cover relative to the lamp housing to rotate the bulb.

[0007] Furthermore, the first transmission assembly includes a first rotating shaft, a second rotating shaft, an incomplete end-face gear, a gear body meshing with the incomplete end-face gear, a first connecting rod, a second connecting rod, and a first ring. The bulb is movably connected inside the first ring. The second rotating shaft is fixedly connected to the inner wall of the lampshade. The gear body is rotatably sleeved on the second rotating shaft. The incomplete end-face gear is fixedly connected to the top of the lamp housing. The second connecting rod is fixedly connected to the end of the gear body near the lamp holder. One end of the first connecting rod is rotatably connected to the second connecting rod through the first rotating shaft. A guide assembly is provided between the first connecting rod and the circumferential side of the first ring.

[0008] Furthermore, the guide assembly includes a first slider, and a first groove is vertically formed on the inner wall of the lampshade. The first slider is slidably connected in the first groove, one end of the first slider is fixedly connected to a first ring, and the other end of the first connecting rod is rotatably sleeved on the first slider.

[0009] Furthermore, the second transmission component includes a first pushing block, a second pushing block, an abutting block, and a second ring. The bulb includes a base and a glass shell, the base and the glass shell being detachably connected. A groove is formed in the first ring, the second ring is detachably connected to the base and movably connected in the groove, the abutting block is disposed on the second ring, and the first pushing block and the second pushing block are fixedly connected to the top wall of the groove. The first pushing block and the second pushing block respectively abut against the abutting block.

[0010] Furthermore, a first rubber pad is provided on the top wall of the groove, a second rubber pad is provided on the bottom wall of the groove, and the second ring is located between the first rubber pad and the second rubber pad.

[0011] Furthermore, both the first rubber pad and the second rubber pad are annular, and the outer diameter of the first rubber pad is smaller than the outer diameter of the second rubber pad.

[0012] Furthermore, a second sliding groove is provided on the top of the lamp housing, and a second slider is fixedly connected to the bottom of the lamp shade, the second slider being slidably connected within the second sliding groove.

[0013] Furthermore, a slot is provided on the inner wall of the second slide groove, and a locking block is fixedly connected to one end of the second slider facing the slot, the locking block engaging with the slot.

[0014] Furthermore, the second groove is arc-shaped.

[0015] Furthermore, a retaining ring is screwed onto the first slider, and the first connecting rod is located between the retaining ring and the first ring.

[0016] Compared with the prior art, the beneficial effects provided by the present invention are as follows: the LED smart street light head connection assembly first installs the bulb inside the lamp cover, and during the process of installing the lamp cover onto the lamp housing, the bulb is driven to be installed onto the lamp holder through the cooperation between the first transmission component and the second transmission component. This simplifies the installation process, and when disassembling, the bulb is removed together with the lamp cover, which avoids the phenomenon of the bulb falling and being damaged during the disassembly of the bulb alone. It can also adapt to the installation of bulbs of different specifications. Attached Figure Description

[0025] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0026] Please see Figure 1-6 The present invention provides a technical solution: the LED smart street light head connection assembly includes a lamp housing 1, a lamp holder 3 disposed inside the lamp housing 1, a light bulb, a lamp cover 2, a first transmission component, and a second transmission component. The light bulb is movably connected inside the lamp cover 2, and the light bulb and the lamp holder 3 are detachably connected. The lamp cover 2 is rotatably engaged with the lamp housing 1. During the rotation of the lamp cover 2 relative to the lamp housing 1, it has a first stroke and a second stroke in sequence. The first transmission component receives the drive of the first stroke during the rotation of the lamp cover 2 relative to the lamp housing 1 to move the light bulb down, and the second transmission component receives the drive of the second stroke during the rotation of the lamp cover 2 relative to the lamp housing 1 to rotate the light bulb.

[0027] As a preferred technical solution, the first transmission assembly includes a first rotating shaft 11, a second rotating shaft 25, an incomplete end-face gear 14, a gear body 13 meshing with the incomplete end-face gear 14, a first connecting rod 10, a second connecting rod 12, and a first ring 7. The bulb is movably connected inside the first ring 7. The second rotating shaft 25 is fixedly connected to the inner wall of the lampshade 2. The gear body 13 is rotatably sleeved on the second rotating shaft 25. The incomplete end-face gear is fixedly connected to the top of the lamp housing 1. The second connecting rod 12 is fixedly connected to one end of the gear body 13 near the lamp holder 3. One end of the first connecting rod 10 is rotatably connected to the second connecting rod 12 through the first rotating shaft 11. A guide assembly is provided between the first connecting rod 10 and the circumferential side of the first ring 7. Specifically, the lampshade 2... During the first stroke of the rotation of the lamp housing 1, the gear body 13 revolves with the lamp cover 2. At the same time, the gear body 13 meshes with the incomplete end face gear 14 and rotates axially around the second rotating shaft 25. The gear body 13 drives the second connecting rod 12 to rotate. The angle between the end of the first connecting rod 10 near the second connecting rod 12 and the end of the second connecting rod 12 near the first connecting rod 10 gradually decreases. Meanwhile, the other end of the first connecting rod 10 moves vertically downward under the action of the guide component. Since the other end of the first connecting rod 10 is rotated and sleeved on the first slider 8, the first ring 7 drives the bulb set in the first ring 7 to move vertically downward toward the lamp holder 3. If the bulb is a snap-on bulb, the snap-on installation between the bulb and the lamp holder 3 can be realized.

[0028] As a preferred technical solution, the guide component includes a first slider 8, and a first groove 9 is vertically provided on the inner wall of the lampshade 2. The first slider 8 is slidably connected in the first groove 9. One end of the first slider 8 is fixedly connected to the first ring 7, and the other end of the first connecting rod 10 is rotatably sleeved on the first slider 8. Specifically, since the first groove 9 is vertically set, it restricts the horizontal displacement of the first ring 7, so that the first ring 7 moves vertically along the first groove 9 with the first slider 8, which can drive the bulb to move toward the lamp holder 3.

[0029] As a preferred technical solution, the second transmission assembly includes a first pushing block 20, a second pushing block 21, an abutting block 22, and a second ring 23. The bulb includes a base 4 and a glass shell 5, with the base 4 and glass shell 5 detachably connected. A groove 6 is formed inside the first ring 7. The second ring 23 is detachably connected to the base 4 and movably connected within the groove 6. The abutting block 22 is disposed on the second ring 23. The first pushing block 20 and the second pushing block 21 are fixedly connected to the top wall of the groove 6, and the first pushing block 20 and the second pushing block 21 respectively abut against the abutting block 22. Specifically, when the bulb is inserted into the bulb holder 3, if the bulb is a bayonet bulb (a bayonet bulb refers to...), the second pushing block 20 is a type of bulb with a bayonet mechanism. A bulb with a bayonet at the tail is also called an insert bulb. Its connection method is to directly insert the bulb into the lamp holder 3, and then rotate it inward to lock the bulb into the lamp holder 3. During the second stroke of the rotation of the lamp cover 2 relative to the lamp housing 1, the gear body 13 does not mesh with the incomplete cross-section gear. At this time, the bulb has been inserted into the lamp holder 3. The second pushing block 21 pushes the abutment block 22 to rotate, causing the bulb to rotate without vertical displacement, which can realize the installation of the bayonet bulb. The first pushing block 20 pushes the abutment block 22 in the opposite direction when the lamp cover 2 is removed, thereby removing the bulb from the lamp holder 3. Preferably, the base 4 is screwed onto the inner wall of the second ring 23 for easy bulb replacement.

[0030] As a preferred technical solution, a first rubber pad 19 is provided on the top wall of the groove 6, and a second rubber pad 24 is provided on the bottom wall of the groove 6. The second ring 23 is located between the first rubber pad 19 and the second rubber pad 24. Specifically, the groove 6 is annular. If the bulb is a screw-type bulb, the first ring 7 drives the bulb located in the first ring 7 to move vertically downward toward the lamp holder 3. At this time, the bulb base 4 stays on the top of the lamp housing 1. The lamp housing 1 has an internal thread. The second pushing block 21 pushes the abutment block 22 to rotate, causing the bulb to rotate. At the same time, the second rubber pad 24 is thick enough to accommodate the vertical displacement of the bulb during the screw connection between the bulb and the lamp housing 1, thus realizing the installation of the screw-type bulb.

[0031] As a preferred technical solution, both the first rubber pad 19 and the second rubber pad 24 are annular. The outer diameter of the first rubber pad 19 is smaller than the outer diameter of the second rubber pad 24. Specifically, the first rubber pad 19 and the second rubber pad 24 are the same as the inner diameter of the first ring 7. The first rubber pad 19 and the second rubber pad 24 can squeeze the top and bottom of the second ring 23 to a certain extent, so that the bulb is stably installed in the first ring 7 during the first stroke of the lamp cover 2 rotating relative to the lamp housing 1.

[0032] As a preferred technical solution, the top of the lamp housing 1 is provided with a second sliding groove 17, and the bottom of the lamp shade 2 is fixedly connected with a second slider 15. The second slider 15 is slidably connected in the second sliding groove 17. Specifically, the second sliding groove 17 is arc-shaped. Through the cooperation between the second sliding groove 17 and the second slider 15, the lamp shade 2 can rotate along the direction of the second sliding groove 17, which plays a guiding role for the lamp shade 2.

[0033] As a preferred technical solution, a slot 18 is provided on the inner wall of the second slide groove 17, and a locking block 16 is fixedly connected to one end of the second slider 15 facing the slot 18. The locking block 16 engages with the slot 18. Specifically, when the lamp cover 2 is rotated to the point where the locking block 16 engages with the slot 18, the lamp cover 2 is installed on the lamp housing 1, and the bulb is also installed on the lamp holder 3.

[0034] As a preferred technical solution, a retaining ring 26 is screwed onto the first slider 8, and the first connecting rod 10 is located between the retaining ring 26 and the first ring 7. Specifically, the retaining ring 26 can prevent the first ring 7 from causing the bulb to shift horizontally, which would cause the bulb to tilt during installation and lead to installation failure.

[0035] Working principle: The LED smart street light head connection assembly first installs the bulb inside the lamp cover 2. During the first stroke of the lamp cover 2 rotating relative to the lamp housing 1, the gear body 13 revolves with the lamp cover 2. At the same time, the gear body 13 meshes with the incomplete end face gear 14 and rotates axially around the second rotating shaft 25. The gear body 13 drives the second connecting rod 12 to rotate. The angle between the end of the first connecting rod 10 near the second connecting rod 12 and the end of the second connecting rod 12 near the first connecting rod 10 gradually decreases. Meanwhile, the other end of the first connecting rod 10 moves vertically downward under the action of the guide component. The other end of 10 is rotated and sleeved on the first slider 8. Then the first ring 7 drives the bulb set in the first ring 7 to move vertically downward toward the lamp holder 3. During the second stroke of the lamp cover 2 rotating relative to the lamp housing 1, the gear body 13 does not mesh with the incomplete cross section gear. At this time, the bulb has been inserted into the lamp holder 3. The second push block 21 pushes the abutment block 22 to rotate, driving the bulb to rotate without vertical displacement. This simplifies the installation process. When disassembling, the bulb is removed together with the lamp cover 2, which avoids the phenomenon of the bulb falling and being damaged during the disassembly process. It can also adapt to the installation of bulbs of different specifications.

[0036] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
