[0044] See Figures 1 to 15 , an improved track light in the present application includes a track 1, a movable main body 3 disposed in the track 1, and a lamp body 2 disposed on the main body 3. The lamp body 2 is disposed in a lamp body mounting seat 326 on the main body 3 through a connecting column 21. A driving wheel 371 is provided on the main body 3, and a positioning strip 12 matching the driving wheel 371 is provided on the track 1. During the rotation of the driving wheel 371, continuous positioning and force application are carried out between the driving wheel 371 and the positioning strip 12 through positioning points, and the main body 3 is driven to move on the track 1; the positioning and force application of the positioning points act on the force application points along the direction of the positioning strip 12 to support the movement of the main body 3 on the track.

[0045] Regarding the specific structures of the driving wheel 371 and the positioning strip 12, the present application provides three specific embodiments, which may also be other equivalent or similar technical solutions. The three embodiments are as follows.

[0046] Embodiment 1, as shown in the accompanying drawings, the driving wheel 371 is a gear, the positioning strip 12 is a rack, the positioning point is the meshing point between the gear and the rack, and the force application point is the contact point between the tooth groove side wall on the rack and the tooth outer wall on the gear. During the rotation of the driving wheel 371, the tooth groove side wall supports the tooth outer wall for the driving wheel 371 to apply force and move. The supporting force is strong, and there will be no slipping or falling, which can well meet the requirements of vertical movement and climbing.

[0047] Embodiment 2: The driving wheel 371 is a gear, the positioning strip 12 is a perforated strip 127, the positioning point is the meshing point between the gear and the hole 128 on the perforated strip, and the force application point is the contact point between the inner wall of the hole on the perforated strip and the outer wall of the tooth on the gear. During the rotation of the driving wheel 371, the inner wall of the hole supports the outer wall of the tooth to provide a force application point for the driving wheel 371 and enables it to move. The supporting force is strong, and there will be no slipping or falling, which can well meet the requirements of vertical movement and climbing. The schematic diagram of this structure is as shown in Figure 15 shown.

[0048] Embodiment 3: The driving wheel 371 is a sprocket, the positioning strip 12 is a chain, the positioning point is the meshing point between the sprocket and the link hole on the chain, and the force application point is the contact point between the inner wall of the link hole of the link hole and the outer wall of the tooth on the sprocket. During the rotation of the driving wheel 371, the inner wall of the link hole supports the outer wall of the tooth to provide a force application point for the driving wheel 371 and enables it to move. The supporting force is strong, and there will be no slipping or falling, which can well meet the requirements of vertical movement and climbing.

[0049] Moreover, in the present application, a driven wheel 372 is further provided on the main body 3. The driving wheel 371 is driven by a driving motor 37. The cooperation mode between the driven wheel 372 and the positioning strip 12 is the same as the cooperation mode between the driving wheel 371 and the positioning strip 12. In this structure, the setting of the two wheels, the driving wheel 371 and the driven wheel 372, has better stability and is more stable during movement.

[0050] As can be seen from the above description in combination with the drawings, in the track lamp of the present application, a unique structure of the driving wheel 371 and the positioning strip 12 is adopted. During the rotation of the driving wheel 371, the force application point between it and the positioning strip 12 can provide a supporting force, and this supporting force can resist the vertical gravity, ensuring that after the track lamp is installed vertically or vertically inclined, the main body 3 and the lamp body 2 thereon can also move on the track without slipping or falling.

[0051] In addition, from the attached Figure 12 to the attached Figure 14As can be seen, a guide wheel mechanism 35 is provided on the main body 3. An extended guide wheel 351 is provided on the guide wheel mechanism 35. The guide wheel 351 is placed in a guide wheel groove 15 on the track 1, which plays a very good role in rolling guidance during the movement of the main body 3. Specifically, the guide wheel mechanism 35 includes a mounting frame 354 positioned on the main body 3. A mounting seat 3515 is provided in the mounting frame 354. The guide wheel 351 is provided on the mounting seat 3515. And, a convex column 3511 is provided on the mounting seat 3515. The convex column 3511 is slidably arranged in a chute 3541 on the mounting frame 354, and a return spring 3513 is also provided on the mounting seat 3515. The guide wheel mechanism 35 further includes a retraction structure. The retraction structure can act on the convex column 3511 and cause the convex column 3511 to slide along the chute 3541, so that the mounting seat 3515 retracts against the elastic force of the return spring 3513, causing the guide wheel 351 to retract. In this state, the guide wheel 351 retracts from the guide wheel groove 15, and at this time, the main body 3 can be taken out from the track 1. In the working state, the retraction structure releases force, and the return spring 3513 pushes out the mounting seat 3515, so that the guide wheel 351 is placed in the guide wheel groove 15.

A retraction guide groove 3531 is provided on the groove plate 353. The convex column 3511 is placed in the retraction guide groove 3531 after protruding from the chute 3541. The structure of the retraction guide groove 3531 is such that when the retraction member 352 moves, the retraction guide groove 3531 drives the convex column 3511 to move and causes the convex column 3511 to slide along the chute 3541, so that the mounting seat 3515 retracts against the elastic force of the return spring 3513, causing the guide wheel 351 to retract.

At least one conductive member 62 in one conductive group is used for electrical contact with the conductive strip 131 in one track unit, and at least another conductive member 62 is used for electrical contact with the conductive strip 131 in another adjacent track unit. The several conductive members 62 in the same conductive group are electrically conductive to each other. This structure can ensure that after two adjacent track units are assembled, the conductive strip 131 can be electrically connected through the conductive group, ensuring the smoothness of the circuit after the track units are connected in series.

[0057] In the present application, two conductive strips 131 are provided in the track unit. Two corresponding groups of insulating conductive groups are provided on the substrate 61. Each group of conductive groups is used for electrical connection with the corresponding conductive strip 131.

[0058] In the present application, the substrate 61 is a PCB board. The substrate 61 is provided outside the track unit, and the conductive strip 131 is provided inside the track unit.

The grafting strip plate 82 is arranged in the strip plate assembly groove 821, and the assembly structure is stable. Specifically, there are four grafting strip plates 82, two of which are respectively arranged on the upper parts on both sides of the track unit, and the other two are arranged at the bottom of the track unit.

[0061] In this application, an end plate 9 is provided at the outer end of the track unit at the end, and a wiring structure is also provided. The inner end of the wiring structure is electrically connected to the conductive bar 131. The wiring structure passes through the end plate 9 for wiring and is connected to the power grid.
