[0048] The following further elaborates on specific embodiments of the present invention based on the accompanying drawings. It should be understood that the description of the embodiments of the present invention herein does not limit the protection scope of the present invention.

[0049] As Figures 1 to 10 shown, the track adapter 1000 of the present invention can be used alone or integrated with the driving power supply. As long as the housing of the driving power supply is defined as the mounting base 100 of the present invention, and other components of the track adapter 1000 for fixing and installation are used, the remaining structure remains unchanged. When the track adapter 1000 is used alone, it is directly connected to the positive and negative electrodes of the lamp or a separate driving power supply. This embodiment is described by taking the integration as an example.

[0050] The driving power supply 2000 of this embodiment includes a power supply housing 2001, a circuit board 2002 disposed in the power supply housing, and a track adapter 1000.

[0051] Among them, removing the power supply housing 2001 and the circuit board 2002, the track adapter 1000 can exist independently. The track adapter 1000 in this embodiment includes: a mounting base 100, a power taking column 200, an adjusting conductive part 300, an adjusting knob 400, and a transmission mechanism 500. The mounting base 100 is used to carry other components, which can be the power supply housing 2001 itself or another component manufactured separately for ease of manufacturing and installation. In this embodiment, the mounting base 100 includes the power supply housing 2001 and a mounting piece 103 fixed on the power supply housing 2001. The mounting base 100 is provided with a first central axis 101, and the power taking column 200 is rotatably arranged on the mounting base 100 around the first central axis 101. The power taking column 200, as a structure for cooperating with the track, can be inserted into the track groove and achieve electrical connection after rotation. In this embodiment, the column body of the power taking column 200 is provided with a negative conductive sheet 201 and at least two positive conductive sheets 202. In the present invention, the definitions of negative and positive poles are as follows: L and N are symbols in alternating current. The "live wire" of single-phase alternating current L is the positive pole, and N is the "neutral wire" of single-phase alternating current, which is the negative pole. In direct current, "+" represents the positive pole and "-" represents the negative pole. For the multi-line track of the prior art, such as a four-line track, which is a standard part, its structure is generally a U-shaped profile, and multiple card slots extending in the length direction are provided on both sides for arranging the conductive metal strips L1, conductive metal strips L2, conductive metal strips L3, and the conductive metal strip N. Of course, all the conductive metal strips can also be arranged on a single side, or different numbers can be arranged on both sides and other solutions. This is the prior art and will not be elaborated. The negative conductive sheet 201 and the positive conductive sheet 202 on the column body of the power taking column 200 are arranged correspondingly. After the power taking column 200 extends into the track and rotates, the negative conductive sheet 201 and the positive conductive sheet 202 can be in contact with the corresponding conductive metal strips to achieve conduction.

[0052] Among them, the negative electrode conductive sheet 201 needs to be in constant contact, and one of the positive electrode conductive sheets 202 is selected for conduction. The specific method is as follows: All the positive electrode conductive sheets 202 extend to the bottom of the power-taking column 200 to form positive electrode contacts 2021, and all the positive electrode contacts 2021 are arranged at intervals around the first central axis 101; The adjusting conductive part 300 is located at the bottom of the power-taking column 200 and is rotatably arranged on the mounting seat 100 around the first central axis 101. It is provided with a conductive contact 301 movably connected to the bottom of the power-taking column 200. The moving path of the conductive contact 301 passes through all the positive electrode contacts 2021. When the power-taking column 200 rotates to be connected to the track, the conductive contact 301 contacts and conducts with which positive electrode contact 2021, that is, it conducts with the corresponding conductive metal strip. The movable connection can be abutment, or it can be the cooperation of a plug and an annular groove. In order to make the conductive contact 301 conduct with different positive electrode contacts 2021, the adjusting knob 400 is rotatably arranged on the mounting seat 100 outside the top of the power-taking column 200, and the transmission mechanism 500 is used for transmitting and connecting the adjusting knob 400 and the adjusting conductive part 300. Rotating the adjusting knob 400, the transmission mechanism 500 transmits the stroke of the adjusting knob 400 to the adjusting conductive part 300, and the adjusting conductive part 300 rotates to the designed position. When the power-taking column 200 rotates in place, it conducts with the required conductive metal strip.

[0053] In this embodiment, the adjusting knob 400 is arranged outside the top of the power-taking column 200, which is convenient for manual adjustment, especially when the track adapter 1000 is installed in a deep and narrow structure. For the convenience of external connection, the adjusting conductive part 300 further includes a fixedly arranged positive electrode conductive connector 304 and a negative electrode conductive connector 305. The positive electrode conductive connector 304 is in constant conduction with the conductive contact 301. In this embodiment, the positive electrode conductive connector 304 is in constant conduction with the conductive contact 301 through a conductive ring; When the negative electrode conductive sheet 201 rotates to the position connected to the track, the negative electrode conductive connector 305 conducts with the negative electrode conductive sheet 201.

[0054] There are many implementation forms of the transmission mechanism 500, such as screw transmission, gear transmission, rack transmission, etc. In this embodiment, in order to simplify and facilitate manufacturing, the mounting base 100 is provided with a second central axis 102 parallel to the first central axis 101. The transmission mechanism 500 includes: a first transmission gear 501 and a second transmission gear 502. The first transmission gear 501 is located at the bottom of the power-taking column 200 and is fixedly connected to the adjusting conductive part 300, and the gear shaft coincides with the first central axis 101. The second transmission gear 502 meshes with the first transmission gear 501 and is rotatably arranged on the mounting base 100 around the second central axis 102. The adjusting knob 400 is fixedly connected to the second transmission gear 502. Two mounting holes for mounting the first transmission gear 501 and the second transmission gear 502 are provided on the mounting piece 103, and the rotational connection is realized through a snap structure.

[0055] In order to make the conductive contact 301 and the positive electrode contact 2021 conduct stably, the bottom of the power-taking column 200 expands radially to form a conductive disk 203. The positive electrode contact 2021 is a sheet attached to the bottom surface of the conductive disk 203, and the conductive contact 301 abuts against the bottom surface of the conductive disk 203. The sheet structure has a large contact area, which can avoid the connection instability caused by manufacturing and assembly errors.

[0056] The negative conductive sheet 201 is different from the positive conductive sheet 202. It does not need to be selected. It only needs to wait until the power-taking column 200 rotates in place. However, for the convenience of overall manufacturing, the negative conductive sheet 201 extends to the bottom of the power-taking column 200 to form a negative electrode contact 2011. And in this embodiment, the negative electrode contact 2011 and the positive electrode contact 2021 are also arranged on the same surface and arranged together.

[0057] The structure of the adjusting conductive part 300 is designed in cooperation with the bottom of the power-taking column 200. In this embodiment, it includes an adjusting disk 302 and an annular conductive sheet 303. There is a shaft hole 3021 in the middle of the adjusting disk 302, which is circumferentially opposite to the positive electrode contact 2021 on the bottom surface of the conductive disk 203. Through holes 3022 are provided in the circumferential direction. A rotating shaft 2031 matching the shaft hole 3021 is provided in the middle of the bottom surface of the conductive disk 203. The annular conductive sheet 303 is arranged on the bottom surface of the adjusting disk 302 and is provided with a conductive elastic sheet passing through the through hole 3022 as the conductive contact 301.

[0058] This embodiment is used to cooperate with a four-wire track of common standard parts. The positive conductive sheet 202 is provided with three. They are respectively connected to the conductive metal strip L1, the conductive metal strip L2, and the conductive metal strip L3. This part is prior art and will not be elaborated.

[0059] In order to facilitate manual installation, in this embodiment, the power-taking column 200 is provided with a protruding rotating handle 204.

[0060] The above-mentioned track adapter 1000 can be independently produced, manufactured and installed. In this embodiment, it is integrated into the drive power supply. Specifically, the mounting base 100 is fixedly arranged on the power supply housing 2001. The power supply housing 2001 is formed by splicing a left part 2007 and a right part 2008. The positive conductive connector 304 is connected to the positive input terminal of the circuit board 2002, and the negative conductive connector 305 is connected to the negative input terminal of the circuit board 2002. The connection method can be plugging or welding, which is the prior art and will not be elaborated.

There are three positive conductive sheets 202, which are grouped in pairs with the negative conductive sheet 201 and arranged on both sides of the power taking column 200. The power taking holes 2004 are provided on both sides of the power supply housing 2001.

[0062] The track adapter 1000 of this embodiment is particularly applicable to the track light of this embodiment. The track light includes a lamp holder 3000, and a light source assembly 4000, a drive power supply 2000 and a track adapter 1000 are arranged on the lamp holder 3000. The lamp holder drive power supply includes a power supply housing 2001 and a circuit board 2002 arranged in the power supply housing. The mounting base 100 is fixedly arranged on the power supply housing 2001. The positive conductive connector 304 is connected to the positive input terminal of the circuit board 2002, and the negative conductive connector 305 is connected to the negative input terminal of the circuit board 2002.

[0063] The lamp holder of this embodiment can be designed to wrap the entire track, which is neat and beautiful. The lamp holder 3000 includes a U-shaped profile 3001 with an upward opening and end caps 3002 arranged at both ends of the U-shaped profile 3001.

To facilitate the installation of the transmission mechanism 500, the width of the lower part 2006 is greater than that of the upper part 2005 and is used to accommodate the mounting base 100 and the transmission mechanism 500.
