[0033] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0034] like Figure 1-6As shown, a multi-directional rail-mounted LED lamp power drive device is used in rail-mounted LED lamps. The power drive device can be assembled with multiple rails of different angles and directions to supply power to the conductive plates of the rails, thereby providing power for the LED lamps installed on the rails. The multi-directional rail-mounted LED lamp power drive device includes a bottom shell 10, a connection seat 20, and a connection cover 30, wherein the connection cover 30, the connection seat 20, and the bottom shell 10 are assembled with each other from top to bottom in sequence. After the assembly is completed, the entire power drive device is roughly in a round cake shape. Compared with the previous cubic-shaped power drive box, the appearance is more beautiful and more convenient to install and use.

[0035] More specifically, the bottom shell 10 has a cavity 101 with an opening facing upward, and two supporting partitions 103 are arranged in the cavity 101. The supporting partitions 103 are horizontally arranged in the cavity and connected to the inner wall of the cavity 101 at both ends, and are used to enclose the inner wall of the cavity 101 and divide the cavity 101 into three grooves. The middle groove is a receiving groove 102 for installing the power module 40, and the grooves on both sides of the receiving groove 102 can be used to match and install the connecting seat 20, and the bottom of the connecting seat 20 is supported by the supporting partitions 103. The bottom shell 10 supports the connecting seat 20 through the supporting partitions 103 in the cavity 101, which is used to make the assembly between the connecting seat 20 and the bottom shell 10 more stable and reliable, the overall structure of the power driving device is more solid, and the compactness of the power driving device is improved.

[0036] The connecting base 20 is installed above the cavity 101 of the base shell 10, so that the power module 40 is located between the base shell 10 and the connecting base 20. A positioning groove 203 is provided at the bottom of the connecting base 20. When the connecting base 20 is installed, the positioning groove 203 is embedded in the top of the power module 40, and then the power module 40 is positioned and installed, thereby improving the installation stability of the power module 40.

[0037] The positioning groove 203 is provided with a plurality of heat dissipation holes 204 connected to the top of the connection seat 20, which dissipate heat for the power module 40 to prevent overheating. A power connector 41 and a wire collection groove 202 are provided on the top of the connection seat 20. The power connector 41 is electrically connected to the power module 40, and is electrically connected to the conductive plate of the guide rail a through the power connector 41 to provide power for the guide rail a; the wire collection groove 202 is provided to collect the wires arranged when the power module 40 or the LED lamp is electrically connected, so that the wiring of the power drive is more neat and the accidental risk of electrical connection is reduced.

[0038] The connection cover 30 is installed on the connection seat 20, and the connection cover 30 has an annular cover plate 301 and a plurality of position-limiting protrusions 302 arranged circumferentially along the annular cover plate 301. The sizes of the plurality of position-limiting protrusions 302 can be set to be inconsistent, and two adjacent position-limiting protrusions 302 are spaced a certain distance apart on the annular cover plate 301 to form a position-limiting slot for installing the guide rail a, thereby forming a plurality of position-limiting slots in the circumferential direction of the annular cover plate 301. The plurality of position-limiting slots are connected to the middle of the annular cover plate 301, and a middle hole penetrating the two side surfaces is also provided in the middle of the annular cover plate 301.

[0039] Therefore, when installing multiple guide rails a, one end of the multiple guide rails a is correspondingly installed on a plurality of limiting notches, and when they are gathered in the middle of the annular cover plate 301, they are electrically connected through the guide rail connector b. Since limiting notches of different angles and directions are arranged in the circumference of the annular cover plate 301, guide rails a arranged in different directions can be installed through these limiting notches, so that multiple guide rails a are electrically connected and fixedly connected to each other. The power connector 41 is installed on the connection seat 20 and extends upward from the surface of the limiting notch, so that the plug-in sheet of the power connector 41 is electrically connected to the conductive plate of the guide rail a, providing power to the guide rail a.

[0040] In this way, the present application sets a plurality of limiting protrusions 302 on the annular cover plate 301 to form a plurality of limiting notches in the circumferential direction of the annular cover plate 301, and the plurality of guide rails a are limitedly assembled through the plurality of limiting notches arranged in an annular array, and one end of the plurality of guide rails a assembled on the limiting notches is electrically connected through the guide rail connector b. Compared with the previous implementation method that the power drive box can only be assembled on one guide rail, the present application can not only realize the electrical connection between the plurality of guide rails a and supply power through the power module 40, improve the stability of the electrical connection between the plurality of guide rails a, but also meet the installation requirements of the guide rails a in multiple directions and angles, solve the problem of the installation and use of the guide rails a being restricted by the environment, and improve the convenience of installation and use of the guide rails a. Moreover, the power drive device of the present application is designed with a roughly round pancake-shaped structure, which is compact and has a high aesthetics.

[0041] In the embodiment of the present application, the limiting notch has a first limiting notch 303 and a second limiting notch 304, wherein the position where the first limiting notch 303 is set on the annular cover plate 301 passes through the assembly hole 3011, and after the connection cover 30 is installed on the connection seat 20, the plug piece of the power connector 41 on the connection seat 20 can be passed through the assembly hole 3011. Therefore, when the guide rail a is installed on the first limiting notch 303, it can also be electrically connected to the guide rail a through the power connector 41, so as to achieve the purpose of providing power to the guide rail a when the guide rail a is installed on the first limiting notch 303.

[0042] In the present application, the two limiting protrusions 302 used to form the second limiting slot 304 are provided with a slot 3021 on the opposite side, and the limiting protrusion 302 of the first limiting slot 303 can also be provided with a slot 3021, through which the slot 3021 of the limiting protrusion 302 can be used to connect the card plate 31 with the buckle 201, and the card plate 31 is connected by the buckle 201 between the limiting protrusions 302 to cover the second limiting slot 304, or to seal the idle second limiting slot 304. Since the card plate 31 is set as an arc plate, when the two ends of the card plate 31 are connected with the buckle 201 of the limiting protrusion 302, the outer side surface of the card plate 31 is flush with the outer periphery of the annular cover plate 301.

[0043] Therefore, by opening a card slot 3021 on the limiting protrusion 302 on both sides of the second limiting slot 304, the card slot 3021 is used to facilitate the assembly of the card plate 31, and the card plate 31 is used to cover or seal the idle second limiting slot 304, thereby further improving the aesthetics of the power drive device; and by installing the card plate 31 on the second limiting slot 304, a certain tension support can be provided to the second limiting slot 304, thereby enhancing the compressive resistance of the entire connecting cover 30.

[0044] In the embodiment of the present application, a plurality of buckles 201 are provided on the top of the connecting base 20, which penetrate through and snap-fit ​​the connecting cover 30 with an annular cover plate 301, so as to realize a detachable connection between the connecting base 20 and the connecting cover 30, thereby eliminating the previous connection method using screws, avoiding damage to components and the inconvenience of disassembly and assembly. In addition, a locking hole 3012 for the buckle 201 to pass through is provided at the position where the limiting protrusion 302 is provided on the annular cover plate 301, and a locking strip 3013 for the buckle 201 to be buckled is provided on the surface of the annular cover plate 301; when installing the connecting cover 30, the buckle 201 of the connecting seat 20 is directly passed through the locking hole 3012, and then the connecting cover 30 is pushed toward the locking strip 3013 of the connecting seat 20 to be buckled with the locking strip 3013. When unlocking, the connecting cover 30 is pushed away from the locking strip 3013, thereby making the buckle 201 on the annular cover plate 301 more firmly connected, convenient to operate, and low in assembly cost.

[0045] The above-mentioned implementation modes are only preferred implementation modes of the present invention, and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
