[0039] Cover 5 DETAILED DESCRIPTION

[0040] like Figure 1 to Figure 2 As shown, a lampshade structure provided by the utility model includes a lampshade shell 1 and a base 2. The lampshade shell 1 has a receiving cavity 11 for receiving a circuit board (not shown in the figure), and the bottom edge of the receiving cavity 11 extends outward to form a mounting plate 12. The mounting plate 12 is provided with a lamp board (not shown in the figure) on its bottom surface and is electrically connected to the circuit board (not shown in the figure), a cover body 5 is assembled on the bottom surface of the mounting plate 12 to shield the lamp board (not shown in the figure), and a plurality of heat dissipation ribs 13 connected to the periphery of the receiving cavity 11 are also arranged on the top surface of the mounting plate 12 at intervals to dissipate the heat generated by the operation of the lamp board. The base 2 includes a lamp holder 3 and a lamp panel 4, the lamp holder 3 is assembled in the lamp panel 4, and the outer peripheral wall of the lamp panel 4 is locked to the inner wall of the receiving cavity 11.

[0041] As mentioned above, the circuit board (not shown) is locked in the accommodating cavity 11 and is symmetrically provided with two contact electrodes 14 protruding upward. In this embodiment, the circuit board is a PCB board, and the two contact electrodes 14 are copper pillars, and the two contact electrodes 14 are symmetrically soldered on the PCB board. An insulating plate 15 is provided on the top surface of the circuit board (not shown) to protect the circuit board (not shown).

[0042] The lamp holder 3 has a base 31 and a top plate 32. The inner periphery of the top plate 32 is provided with at least one elastic buckle 33 extending downward. In this embodiment, two elastic buckles 33 are extended from the top plate. The inner periphery of the base 31 is provided with a buckle groove 34 for the elastic buckle 33 to be clamped, so as to fix the top plate 32 to close the base 31. The bottom of the base 31 is provided with two arc grooves 35 for the contact electrode 14 to be inserted. Each of the arc grooves 35 has a large diameter end 351 and a small diameter end 352, and a conductive sheet 353 is embedded in the base 31 in the small diameter end 352. The conductive sheet 353 is connected to an external power source. One end of the conductive sheet 353 is an enlarged opening 354, and the other end is gradually narrowed to form a contact hole 355 and is closed. During installation, as shown in FIG. 3 , each contact electrode 14 is inserted from the corresponding large diameter end 351 and slides along the arc groove 35 while entering the opening 354 of the conductive sheet 353 . Then, as shown in FIG. 4 , each contact electrode 14 moves into the small diameter end 352 . At this time, the contact electrode 14 contacts the contact hole 355 , thereby forming a power supply circuit to provide power to the circuit board.

[0043] In other possible implementations, such as Figure 5 As shown and combined with the symbol descriptions of Figures 3 and 4, the circuit board (not shown in the figures) is provided with three upwardly protruding contact electrodes 14, and the bottom of the base is correspondingly provided with three arc grooves 35 for inserting the contact electrodes 14, so that the contact electrodes 14 can be inserted from the large diameter end 351 and then slide along the arc groove 35 until the small diameter end 352 contacts the conductive sheet 353 to form a conductive loop.

[0044] Please continue reading Figure 2 As shown, the outer peripheral wall of the base body 31 is recessed inwardly with at least one first mounting hole 36 for the locking component to extend through, and this embodiment is provided with three first mounting holes 36. The top plate 32 is correspondingly provided with three second mounting holes 37, and the locking components can be respectively extended through the first mounting holes 36 and the second mounting holes 37 and locked to the lamp panel 4, so that the lamp holder 3 is assembled in the lamp panel 4 to form an integrated structure, which is convenient for assembly of the lamp cover shell 1. Among them, the top plate 32 is also provided with at least one positioning protrusion 321, and the lamp panel 4 is correspondingly provided with at least one positioning hole 41, so that the positioning protrusion 321 can extend through to locate the installation position of the lamp holder 3 relative to the lamp panel 4, so that the lamp holder 3 can be locked in the lamp panel 4 through the locking components such as hexagonal screws, countersunk screws, etc.

[0045] In addition, at least two guide grooves 42 are arranged along the outer peripheral wall of the lamp panel 4. In this embodiment, three guide grooves 42 are arranged at equal intervals on the outer peripheral wall of the lamp panel 4. The inner wall of the accommodating cavity 11 is correspondingly provided with a guide column 16 that can slide along the guide groove 42. Since the lamp panel 4 is used to be assembled under a ceiling fan, the rotation of the ceiling fan motor will generate vibration, which will cause the lampshade shell 1 and the lamp panel 4 to rotate relative to each other and become loose, and there is a risk of falling off. In order to solve this problem, each guide groove 42 of the utility model forms an arc groove 421 at one end thereof and is closed, and extends at the other end thereof to connect to the bottom periphery of the lamp panel 4 to form an inlet 422. The guide post 16 on the inner wall of the accommodating cavity 11 can slide into the guide groove 42 along the corresponding introduction port 422, and slide along the guide groove 42 and fall into the arc groove 421 as the lampshade shell 1 rotates. The arc groove 421 limits the displacement stroke of the guide post 16, thereby positioning the lampshade shell 1, solving the problem of the lampshade shell 1 loosening due to inertial centrifugal force.

[0046] In order to ensure accurate alignment for installation, the utility model also provides an installation indicator groove 43 on the outer peripheral wall of the lamp panel 4, and the installation indicator groove 43 is arranged between the two guide grooves 42. In detail, the installation indicator groove 43 forms a rectangular groove 431 at one end and is closed, and extends to the bottom periphery of the lamp panel 4 at the other end to form an installation indicator opening 432. The inner wall of the accommodating cavity 11 is correspondingly provided with a rectangular installation block 17. During installation, the installation block 17 is first slid upward from the installation indicator opening 432, at which time each guide column 16 is aligned with the introduction opening 422 of each guide groove 42 and slides in; then the lampshade shell 1 is rotated to make the installation block 17 slide along the installation indicator groove 43 and fall into the rectangular groove 431, and each guide column 16 simultaneously slides along each guide groove 42 and falls into the arc groove 421, and the lampshade shell 1 is combined with the lamp panel 4 and rotated and fixed by the cooperation of the installation indicator groove 43 and the installation block 17 to assist in positioning.

[0047] The present invention also has a plurality of retractable contact members (not shown) at the bottom of the seat body 31. The contact members are each composed of a contact column and a spring. When pushed, the spring can be compressed to retract the contact column into the seat body 31. When the lampshade shell 1 is installed, the contact members abut against the top surface of the insulating plate 15. Due to the restoring force of the spring, a certain pushing resistance is generated, thereby correcting the installation plane of the lampshade shell 1 to a horizontal plane, ensuring that each guide column 16 slides into the corresponding guide groove 42 synchronously during installation.

[0048] When the present embodiment is actually used, firstly, the mounting block 17 of the lampshade shell 1 is aligned with the mounting indication opening 432 of the mounting indication groove 43, and is pushed upward until each contact piece abuts against the insulating plate 15 in the lampshade shell 1, so as to calibrate the mounting plane to be in a horizontal plane. At this time, the mounting block 17 and each guide post 16 synchronously slide into the corresponding mounting indication opening 432 and the introduction opening 422, and as shown in FIG. 3, each contact electrode 14 also extends into the large diameter end 351 of the arc groove 35 accordingly; then, force is applied to push the lampshade shell 1 upward and rotate it until the lampshade shell 1 can no longer rotate, so that the mounting block 17 and each guide post 16 are positioned above the corresponding rectangular groove 431 and the arc groove 421. When the force is released, the mounting block 17 and the guide posts 16 fall into the rectangular groove 431 and the arc groove 421 respectively under the action of the lampshade shell 1's own weight, so as to position the lampshade shell 1 so that it is locked with the base 2. At the same time, as shown in FIG. 4 , the contact electrode 14 slides along the arc groove 35 to the small diameter end 352 and contacts the conductive sheet 353 to form a power supply circuit, thereby providing power to the circuit board, so that the lamp board electrically connected to the circuit board is powered on for illumination.

[0049] When replacing the lampshade shell 1, the lampshade shell 1 is pushed upward until it cannot be pushed anymore. At this time, each guide post 16 moves upward from the corresponding arc groove 421, and the limit of each guide post 16 is released. Then the lampshade shell 1 is rotated in the direction opposite to the installation direction, and each guide post 16 slides along the corresponding guide groove 42 to the guide port 422, and the installation block 17 also slides along the installation indicator groove 43 to the installation indicator port 432. After the force is released, the lampshade shell 1 falls off under the action of its own weight, and the lampshade shell 1 can be disassembled.

[0050] The passive angle-adaptive buffer mechanism provided by the present invention has the following technical advances and advantages:

[0051] First, the operation is simple and easy to install and disassemble. The utility model forms a power supply circuit by plugging the circuit board into the conductive sheet of the lamp holder with the contact electrode. There is no need to separate the electrode line from the power line when replacing. The lampshade shell and the lamp panel of the base are rotatably locked, which can be quickly disassembled and installed. The operation is simple and easy to use.

[0052] Second, precise alignment to ensure accurate installation; the utility model provides an installation indicator groove on the outer wall of the lamp panel, and a matching installation indicator block is provided in the accommodating cavity. The combination position of the guide groove and the guide column is positioned by the assembly position of the installation indicator block and the installation indicator groove. A plurality of elastically extendable contact members are also provided at the bottom of the lamp holder. The contact members are elastically pressed against the top surface of the insulating plate to correct the lampshade shell to be in a horizontal plane, thereby accurately positioning the installation position to ensure that the contact electrode is accurately inserted into the arc groove and connected with the conductive sheet.

[0053] The disclosure of the above embodiments is only used to illustrate the present invention, not to limit the present invention. Therefore, any changes in numerical values ​​or replacement of equivalent components should still fall within the scope of the present invention.

[0054] In summary, it should be clear to those familiar with the art that the utility model can indeed achieve the aforementioned objectives and is in compliance with the provisions of the Patent Law, and therefore an application is filed in accordance with the law.
