[0038] Reference Figure 1 The track light of this utility model embodiment includes a sliding mechanism 10 and an LED light 20, wherein, referring to Figures 2 to 20, the track light includes a sliding mechanism 10 and an LED light 20. Figure 5The sliding mechanism 10 includes a strip frame 100, a slider 200, a first magnet 300, a second magnet 400, and a driving mechanism 500. The strip frame 100 extends along its length. A guide rail 110 is provided at the lower part of the strip frame 100, and a protrusion 120 is provided in the middle of the guide rail 110. First grooves 111 are provided on both sides of the protrusion 120 in the cross-section of the strip frame 100. The slider 200 is slidably connected to the guide rail 110. A groove 210 is provided through the slider 200, and the protrusion 120 is embedded in and slidably connected to the groove 210. A through hole 220 is provided in the middle of the slide 200; a first magnet 300 is fixed in the first groove 111; a second magnet 400 is fixed on the inner walls of both sides of the slide 210, the second magnet 400 and the first magnet 300 are in corresponding positions and magnetically attached; a drive mechanism 500 is built into the through hole 220, and the drive mechanism 500 and the two inner sides of the guide rail 110 are in a transmission cooperation to drive the slider 200 to slide in the guide rail 110; wherein, the drive mechanism 500 has a self-locking mechanism to fix the slider 200 at any position of the guide rail 110, and the LED light 20 is connected to the bottom of the slider 200.

[0039] In practical use, the drive mechanism 500 is activated within the through hole 220. Through transmission cooperation with the inner side of the guide rail 110, it provides sliding power for the slider 200, causing the slider 200 to slide along the length of the guide rail 110. At the same time, the protrusion 120 slides synchronously within the groove 210. When fixation is required, the self-locking mechanism is activated, and the drive mechanism 500 stops driving the slider 200, fixing the slider 200 at any position on the guide rail 110. The first magnet 300 and the second magnet 400 constrain the relative position of the strip frame 100 and the slider 200 through magnetic attraction, assisting in stabilizing the sliding process and maintaining the structural stability of the entire sliding mechanism 10.

[0040] In summary, the relative positions of the strip frame 100 and the slider 200 are constrained by the magnetic cooperation between the first magnet 300 and the second magnet 400, which improves the stability of the entire sliding mechanism 10. The self-locking drive mechanism 500 makes it easy to fix the LED light 20 to the desired position.

[0041] Reference Figure 2 and Figure 3As an embodiment of the above technical solution, the drive mechanism 500 includes a drive motor 510 and a rack 113. The drive motor 510 is provided with two drive shafts 520, and each of the two drive shafts 520 is connected to a gear 530. There are two racks 113, and the two racks 113 are respectively fixed in the two inner sides of the guide rail 110. The racks 113 are engaged and meshed for transmission. In the cross-section of the strip frame 100, the two inner sides of the guide rail 110 are provided with a second groove 112, and the rack 113 is fixed on the lower side of the second groove 112.

[0042] In Embodiment 1, the drive motor 510 simultaneously drives two drive shafts 520, causing the gear 530 to rotate. The gear 530 meshes with the corresponding rack 113, generating a bidirectional driving force that pushes the slider 200 to slide along the guide rail 110. The second groove 112 provides installation and positioning space for the rack 113, ensuring the meshing accuracy of the gear 530 and rack 113. Based on the meshing transmission principle of the gear 530 and rack 113, the rotational motion of the motor is converted into the linear motion of the slider 200. The symmetrically arranged gears 530 and rack 113 form a parallel driving force. Utilizing the high rigidity characteristics of mechanical meshing, the transmission stability is ensured. Furthermore, the drive motor 510 has a built-in self-locking mechanism. By cutting off the power to the drive motor 510, it can be ensured that the drive shaft 520 cannot rotate in any direction. At the same time, the meshing between the gear 530 and rack 113 achieves the self-locking purpose of the slider 200 and fixes the position of the LED light 20 installed on the slider 200.

[0043] In addition, refer to Figure 4 and Figure 5 As a second embodiment of the above solution, the drive mechanism 500 includes a drive motor 510 and a rack 113. The drive motor 510 is provided with two drive shafts 520, one of which is connected to a gear 530 and the other is connected to a roller 550. The rack 113 is fixed in one of the inner sides of the guide rail 110, and the rack 113 is meshed and connected to the guide rail 110. In the cross-section of the strip frame 100, the two inner sides of the guide rail 110 are provided with second grooves 112. The rack 113 is fixed on the lower side of one of the second grooves 112, and the roller 550 slides in contact with the lower side of the other second groove 112.

[0044] In Embodiment 2, after the drive motor 510 is started, the gear 530 meshes with the rack 113 on one side to provide driving force, while the roller 550 on the other side rolls in the second groove 112 to reduce frictional resistance and assist the slider 200 in sliding. The sliding engagement between the roller 550 and the second groove 112 bears part of the supporting force and balances the driving force on one side. Similar to Embodiment 2, by cutting off the power to the drive motor 510, it can be ensured that the drive shaft 520 cannot rotate in any direction. At the same time, the meshing between the gear 530 and the rack 113 achieves the self-locking purpose of the slider 200 and fixes the position of the LED light 20 installed on the slider 200.

[0045] Preferably, in Embodiments 1 and 2, the drive motor 510 is a servo motor. The servo motor can receive control signals, precisely adjust its speed and direction, and drive the gear 530 or roller 550 to move. Simultaneously, the servo motor has a built-in self-locking mechanism, which achieves precise positioning and position holding. As a conventional mechanism in the art, the servo motor has a built-in brake self-locking system, which uses electromagnetic force to drive a mechanical structure to lock the motor shaft. When the motor is powered off, the brake spring releases, and the mechanical latch quickly locks the output shaft; when powered on, the electromagnetic coil is energized to generate attraction, releasing the latch, thereby realizing the start and stop of the servo motor.

[0046] In some embodiments, refer to Figure 2 and Figure 4 The top of the strip frame 100 is provided with a fixing part 130, which is fixedly connected to the ceiling, floor or wall by self-tapping screws. During installation, the fixing part 130 is aligned with the preset hole position on the mounting surface, and the self-tapping screw is used to penetrate the fixing part 130 and screwed into the mounting surface material (such as gypsum board or concrete). The strip frame 100 is fixed by the mechanical anchoring force of the screw. The pull-out force and shear force of the self-tapping screw are used to withstand the weight of the track light and the lateral force when the slider 200 slides, so as to achieve reliable fixation.

[0047] In some embodiments, refer to Figure 2 and Figure 4 The slider 200 has mounting grooves 230 on both sides, which correspond to the first groove 111. The first magnet 300 is completely embedded in the first groove 111, and a portion of the second magnet 400 is embedded in the mounting groove 230, while the other portion is embedded in the first groove 111. During assembly, the first magnet 300 is fixed to the first groove 111 of the strip frame 100, and one end of the second magnet 400 is embedded in the mounting groove 230 of the slider 200, while the other end extends into the first groove 111, contacting and fitting with the first magnet 300. The mounting groove 230 provides positioning and support for the second magnet 400, ensuring a tight fit between the first magnet 300 and the second magnet 400. The mating structure of the mounting groove 230 and the groove achieves pre-positioning and rigid support for the first magnet 300, ensuring the long-term stability of the magnetic fit.

[0048] In some embodiments, referring to FIG1, multiple sliders 200 are provided along the length of the guide rail 110. Each slider 200 is independently connected to an LED light and can be individually controlled for sliding and positioning; the multiple sliders 200 are arranged at intervals on the guide rail 110 and can move simultaneously or separately to adjust the position of each LED light.

[0049] Preferably, refer to Figures 1 to 5 The LED light 20 includes a rotating frame 600, a rotating shaft 800, and a light body 700. The rotating frame 600 includes a crossbeam 610 and two connecting edges 620. The two connecting edges 620 are fixedly connected to both ends of the crossbeam 610, so that the rotating frame 600 is U-shaped. One end of the rotating shaft 800 is fixedly connected to the bottom of the slider 200, and the other end is rotatably connected to the crossbeam 610, so that the crossbeam 610 can pivot around the axis of the rotating shaft 800. The light body 700 is built between the two connecting edges 620, and both sides of the light body 700 are rotatably connected to the ends of the two connecting edges 620, so that the light body 700 can pivot around a fixed axis.

[0050] Among them, reference Figure 2 and Figure 4 The rotating frame 600 is connected to the bottom of the slider 200 via the rotating shaft 800, and can pivot horizontally around the axis of the rotating shaft 800 to adjust the illumination direction of the LED light 20; the two ends of the lamp body 700 are rotatably connected to the connecting edge 620, and can pivot vertically around the fixed axis to realize the pitch angle adjustment of the lamp body 700.

[0051] Specifically, refer to Figure 2 and Figure 4 The lamp body 700 has a rotating shaft 710 fixed through it, and both ends of the rotating shaft 710 are rotatably connected to two connecting edges 620 respectively. It should be mentioned that the lamp body 700 also includes lamp beads and an electrical unit. The electrical unit is used to supply power to the lamp beads. Both the lamp beads and the electrical unit are built into the lamp housing. This technical solution is a conventional solution in the lighting field and is not the technical problem to be solved in this application, so it will not be described in detail here.

[0052] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
