Description

Technical Field

[0001] This utility model relates to the field of lighting technology, and in particular to a track light. Background Technology

[0002] Track lights are lighting fixtures installed on a dedicated track, mainly divided into two types: automatically adjustable and manually adjustable. The structure of an automatically adjustable track light is similar to that proposed in Chinese Utility Model No. CN 219102905U, which includes a track, a lamp holder, and a lamp body mounted on the lamp holder. The track has a groove formed within it, with part of the lamp holder placed within the groove, and the lamp body located outside the track. The track light also includes a motion mechanism for driving the lamp holder to move along the length of the track.

[0003] To enable the light-emitting components of the lamp body to automatically adjust the illumination angle, it is also proposed that "the track light further includes a first motor for driving the light-emitting components to rotate and a second motor for driving the light-emitting components to swing". However, the current design is mainly driven by the motor shaft. When the first motor drives the horizontal rotation, there are usually no major problems. But when the second motor drives the light-emitting component to swing up and down, the second motor requires a lot of force because the light-emitting component is heavy and also has a heavy heat sink.

[0004] A similar electrically driven oscillating structure, or as proposed in the Chinese utility model with announcement number CN206093673U, is a "controllable direction motor track light". The rotating output shaft of the up-and-down rotating stepper motor is inserted and fixed on the right side of the lamp body. When the up-and-down rotating stepper motor rotates, it can drive the right side of the lamp body to rotate, so that the rotating output shaft of the left lamp body rotates at the same time, driving the entire lamp body to rotate up and down.

[0005] Because a motor with greater driving force is required, the corresponding motor cost is relatively high and needs improvement. Utility Model Content

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-8 A type of track light, applied to a corresponding track.

[0023] The track light includes a lamp holder 1, and the lamp holder 1 is provided with a motion mechanism 10 for driving the lamp holder to move on the track.

[0024] A connecting rod 2 is provided on the lamp holder 1, and a motor frame 3 is connected to the connecting rod 2. A lamp holder 4 is rotatably connected to the motor frame 3. The lamp holder 4 rotates relative to the motor frame 3 and forms an up-and-down swinging motion. A lighting lamp 5 is installed on the lamp holder 4.

[0025] The motor frame 3 is equipped with a first drive motor 6 for driving the lamp holder to swing up and down, and the lamp holder 4 has a force-receiving part 7 for receiving the power of the rotating output shaft of the first drive motor 6.

[0026] The track light also includes a torque amplification component 8, which increases the torque output from the rotational output shaft of the first drive motor 6 to the force-receiving part 7.

[0027] The torque amplification effect of the torque amplification component 8 amplifies the power output from the rotation output shaft of the first drive motor 6 to the force receiving part 7, making the lamp holder 4 easier to drive to swing up and down, so that the first drive motor 6 can use a smaller driving force to adjust the up and down illumination angle of the lighting lamp 5.

[0028] In some embodiments, a rotating shaft 9 is connected to the motor frame 3, and a rotating shaft seat that rotates with the rotating shaft 9 is connected to the lamp holder 4. The lamp holder 4 is rotatably connected to the motor frame 3 through the rotational engagement of the rotating shaft 9 and the rotating shaft seat.

[0029] In some implementations, the torque amplification component 8 includes an output gear 801 connected to the rotary output shaft of the first drive motor 6. The torque amplification component 8 also includes an internal gear ring or arc rack 802 connected to the force-receiving part 7, wherein the internal teeth of the internal gear ring or arc rack 802 mesh with the external teeth of the output gear 801.

[0030] The center of the internal gear ring or the center of the arc-shaped rack 802 is located on the axial center line of the rotating shaft 9 or on the extension line of the axial center line.

[0031] By using the output gear 801 to reduce speed and increase torque with the internal gear ring or arc rack 802, the first drive motor 6 can more easily drive the lamp holder 4 to swing up and down, thereby realizing the up and down rotation adjustment of the illumination direction of the lighting lamp 5.

[0032] In some embodiments, the motion mechanism 10 includes a second drive motor 11 mounted on the lamp holder 1 and a traveling wheel 12 rotatably connected to the lamp holder. At least a portion of the outer wheel surface of the traveling wheel 12 is in contact with the track. The second drive motor 11 is used to drive the traveling wheel 12 to rotate, and the lamp holder can move on the track by the traveling wheel 12 traveling on the track.

[0033] like Figure 1 , 4 As shown, for example, lamp holder 1 can be configured to travel in the left and right directions.

[0034] In some embodiments, a speed change assembly is further provided between the rotary output shaft of the second drive motor 11 and the traveling wheel 12. The speed change assembly is, for example, a gear transmission assembly, such as a gear reduction assembly, so that the second drive motor can more easily drive the traveling wheel to travel on the track.

[0035] In some embodiments, the lamp holder 1 is further provided with a conductive contact 13, which can be used to contact the conductive strip on the track.

[0036] The lamp holder 1 is also equipped with a power module, which receives power through contact between conductive contacts and conductive strips. For example, it supplies power to the first drive motor, the second drive motor, the lighting lamp, and the third drive motor described below.

[0037] In some embodiments, the connecting rod 2 is tubular and rotatably connected to the lamp holder 1. The connecting rod 2 is vertically oriented, and its rotation center line on the lamp holder is vertically oriented, coinciding with the axis of the connecting rod 2.

[0038] The lamp holder 1 is also equipped with a third drive motor 14 for driving the connecting rod 2. The connecting rod 2 is driven by the third drive motor 14, thereby realizing the left and right turning adjustment of the illumination direction of the lighting lamp 5 on the lamp holder.

[0039] In some embodiments, a speed-changing assembly may also be provided between the rotary output shaft of the third drive motor 14 and the connecting rod 2. For example, the speed-changing assembly is a gear reduction assembly.

[0040] The conduit of the connecting rod 2 can form a wiring conduit 15. For example, the first drive motor and the lighting lamp can be connected to the lamp holder through the conduit of the connecting rod, or connected to the power module on the lamp holder through wire wiring.

[0041] Thus, when the illumination angle of the lighting lamp 5 is adjusted horizontally by the third drive motor 14, the wiring connection passes through the wiring pipe 15 corresponding to the rotation center line of the connecting rod, which makes it less likely to cause wire tangling or twisting.

[0042] More preferably, at the bends of the wires on the motor frame 3 and / or the lamp holder 4, the motor frame 3 and the lamp holder 4 are rounded or rounded to form a rounded or rounded part 16, so that when the lamp holder 4 is rotated and adjusted, it is not easy to cause excessive friction to the wires.

[0043] In some embodiments, the lamp holder 1 is also provided with a retractable slider 17, which can be hung on the track to prevent the lamp holder from detaching from the track.

[0044] Specifically, when the retractable slider is in the retracted state, the portion of the lamp holder with the retractable slider 17 can enter the track; then, the retractable slider is extended, and it can be hung on the track accordingly, thus forming a slider structure that slides and engages with the track. The sliding direction is the same as the travel direction of the lamp holder 1.

[0045] In some embodiments, the lamp holder 1 is provided with an installation space.

[0046] The retractable slider 17 includes an adjustment shaft 1701 rotatably connected within the lamp holder 1. The axis of the adjustment shaft 1701 is set vertically, and the rotation center line of the adjustment shaft 1701 is set vertically.

[0047] The outer peripheral surface of the adjusting shaft 1701 is connected to a horizontally extending connecting arm 1702, and a sliding fit part 1703 is connected to the end of the connecting arm 1702 away from the adjusting shaft.

[0048] The lamp holder 1 has an adjustment side 101 perpendicular to the direction of travel and a mating side 102 parallel to the direction of travel. The mating side 102 has a through hole 103 that communicates with the interior of the lamp holder.

[0049] The adjusting shaft 1701 has a rotational direction that causes the sliding mating part 1703 to pass through the through hole 103 and exit the mating side, and a portion of the edge of the through hole 103 forms a stop for the connecting arm 1702 to be in place; the adjusting shaft 1701 also has a rotational direction that causes the sliding mating part 1703 to pass through the through hole 103 and enter the lamp holder.

[0050] A horizontally arranged rotating adjustment disk 1704 is connected to the adjustment shaft 1701. A first adjustment part 1705 and a second adjustment part 1706 are provided at the centrifugal position of the rotating adjustment disk 1704.

[0051] A tension spring 1707 is provided inside the lamp holder 1. One end of the tension spring 1707 is connected inside the lamp holder 1, and the other end of the tension spring 1707 is connected to the first adjusting part 1705. When the tension spring 1707 performs elastic reset, it pulls the first adjusting part 1705 and causes the adjusting shaft 1701 to rotate in the rotation direction.

[0052] A horizontally arranged adjustment slide rail 1708 is provided on the adjustment side 102, and the length direction of the adjustment slide rail 1708 is perpendicular to the travel direction of the lamp holder 1. An adjustment slider 1709 is slidably arranged on the adjustment slide rail 1708, and an actuating part 1710 extending into the lamp holder is connected to the adjustment slider 1709. The actuating part 1710 is provided with a sliding hole 1711 that slides and engages with the second adjustment part 1706, and the length direction of the sliding hole 1711 is the same as the travel direction of the lamp holder 1.

[0053] By pushing the adjusting slider 1709 on the adjusting side of the lamp holder, the adjusting shaft 1701 is rotated in the inward direction. At this time, the retractable slider is in the retracted state, and the lamp holder 1 can be inserted upward into the track. Then, the adjusting slider 1709 is released, and the tension spring 1707 is reset, so that the adjusting shaft 1701 is rotated in the outward direction. The sliding mating part 1703 is inserted through the mating side 102 and enters the horizontal guide rail of the track to prevent the lamp holder 1 from falling off the track. At this time, the retractable slider is in the extended state.

[0054] The above design allows the track light to be easily installed into the track or easily removed from the track.

[0055] In some embodiments, the lamp holder 1 has a pair of mating sides facing away from each other and a pair of adjusting sides facing away from each other.

[0056] In some embodiments, each mating side has a through hole.

[0057] The adjusting shaft 1701 is connected to two connecting arms, each corresponding to one of the two through holes. Each connecting arm is connected to a corresponding sliding engagement component. That is, when the adjusting shaft rotates in the rotation direction, the sliding engagement component on one connecting arm protrudes through one of the through holes, and the sliding engagement component on the other connecting arm protrudes through the other through hole.

[0058] After the two sliding fitting parts are rotated out of the corresponding through holes, they can form a multi-point fit with the track, making the lamp holder more stable on the track and less likely to fall off.

[0059] like Figure 4As shown, in some embodiments, the lamp holder 1 is provided with two retractable sliders 17, which are spaced apart along the traveling direction of the lamp holder 1. The rotation direction of the first retractable slider is opposite to that of the second retractable slider.

[0060] For example, the first retractable slider's axis rotates clockwise, while the second retractable slider's axis rotates counter-clockwise. By combining positive and negative approaches, when the lamp holder 1 is moving in the same direction and encounters an obstacle, it can prevent all retractable sliders from being pushed into the retracted state by the obstacle, thus effectively ensuring safe movement.

[0061] In some embodiments, the adjustment sliders of the first retractable slider and the adjustment sliders of the second retractable slider are respectively disposed on different adjustment sides.

[0062] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
