Description

Technical Field

[0001] The present invention relates to the technical field of track lights, and in particular to a track-type driving power supply box. Background Art

[0002] In the modern lighting industry, track lights are widely used in commercial spaces, exhibition halls, and other venues due to their advantages such as easy installation and flexible positioning. Track lights generally consist of a driver power box (power converter) and a lamp body connected to its base. Their power supply is derived from conductive metal strips on both sides of the track. One section is a high-voltage metal strip, responsible for providing high voltages such as 110V / 220V / 380V, while the other section is a low-voltage metal strip, responsible for providing low voltages such as 10V / 12V / 24V / 36V. The driver power box is equipped with corresponding lighting connectors, high-voltage switches, and low-voltage switches.

[0003] Current power supply boxes are difficult to improve and shorten in overall length, negatively impacting product competitiveness. The reasons are as follows: Taking the existing patent (CN216307724U) as an example, 1. Existing high-voltage power supply switches typically include a guide rail power connector and a phase adjustment mechanism. This method of powering with a fully extended rotating conductive plate presents significant drawbacks. Firstly, effective power supply requires the use of a phase adjustment mechanism, which requires a large number of components and does not effectively reduce manufacturing costs or improve production efficiency. Secondly, the guide rail power connector and electrode adjustment mechanism are typically arranged side by side in the power supply box, occupying a significant amount of space and contributing to the difficulty in shortening the power supply box. 2. In order to prevent the driving power box from falling off the track under its own weight after being installed on the track, an elastic limiting protrusion is generally provided on the side wall of the power box body near the end. The elastic limiting protrusion cooperates with the anti-slip position in the track to prevent it from falling off. At the same time, although the guide rail power connector for the high-voltage switch is equipped with a limiting structure, the limiting structure can only be extended outward at the same time when the power-taking component is extended to take power, further ensuring that the driving power box will not fall off the track under working conditions. However, providing an elastic limiting protrusion on the power box body will occupy a part of the length of the driving power box.

[0004] It can be seen that the existing technology still needs to be improved and enhanced. Summary of the Invention

[0011] As a further improvement of the above technical solution, the edges of the clamping end of the telescopic limit block are chamfered to form a shift-assisting inclined surface.

[0012] As a further improvement of the above technical solution, the output ends of the neutral wire taking wire and the live wire taking wire are connected to the circuit assembly through a conductive clamp, and the input end forms an arc-shaped power taking hook.

DETAILED DESCRIPTION

[0034] The present invention provides a track-type drive power box. To make the objectives, technical solutions, and effects of the present invention more clear and explicit, the present invention is further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are only intended to illustrate the present invention and are not intended to limit the scope of protection of the present invention.

[0035] See also Figures 1 to 8The present invention provides a track-type driving power supply box, comprising a power supply box body 1, a circuit assembly 2 arranged in the power supply box body 1, a lamp connector 3, a weak current switch 8 and a strong current switch 6; the output end of the circuit assembly 2 is electrically connected to the lamp connector 3, and the input end of the circuit assembly 2 is electrically connected to the weak current switch 8 and the strong current switch 6 respectively; the strong current switch 6 comprises a first rotating seat 61 rotatably arranged in the power supply box body 1, a cam structure 62 and a limiting structure 63 arranged on the first rotating seat 61, and a neutral line 644 and a neutral line 64 arranged beside the cam structure 62. There are three live wire taking-in wires, and the first rotating seat 61 rotates to form a power-off position and three power-on positions. The first rotating seat 61 is used to drive the cam structure 62 to rotate. When in any power-on position, the cam structure 62 drives the neutral wire taking-in wire 644 and one of the live wire taking-in wires to pop outward; when in the power-off position, the neutral wire taking-in wire 644 and all the live wire taking-in wires retract inward; the limiting structure 63 includes two symmetrically arranged first fixed limiting blocks 632 and two symmetrically arranged telescopic limiting blocks 631; the first fixed limiting blocks 632 and the telescopic limiting blocks 631 are arranged in a circular array.

[0036] Before installing the driving power box, the high-voltage switch 6 needs to be adjusted to the power-off position. At this time, the neutral wire 644 and all the live wires are retracted into the power box body 1, and the two telescopic limit blocks 631 are in the extended state. When the driving power box is inserted into the track 4 from bottom to top, the extended telescopic limit block 631 will contact the track 4. Under the squeezing action of the track 4, the telescopic limit block 631 will overcome the resistance of the internal elastic structure and automatically retract, providing a clearance space for the insertion of the driving power box, ensuring that the driving power box can be smoothly inserted into the track 4. After the driving power box is fully inserted into place, the telescopic limit block 631, which has lost the squeezing of the track 4, will re-extend under the restoring force of the elastic structure, and will work closely with the anti-slip position 44 in the track 4 to prevent the driving power box from falling off the track 4 during use, causing damage to the driving power box and the lamp, and causing injuries.

[0037] When the first rotating seat 61 is in the power-off position, the shape of the cam structure 62 does not exert pressure on the neutral wire taking wire 644 and the live wire taking wire. The neutral wire taking wire 644 and the live wire taking wire both retract inward and return to their natural state, completely separating from the high-voltage metal strip in the track 4, cutting off the power connection and ensuring safe power off.

[0038] When the first rotating base 61 rotates to any power-connection position, the cam structure 62 rotates synchronously with the first rotating base 61. The change in its outer contour generates a mechanical thrust on the live wire at the corresponding position. Simultaneously, the neutral wire 644 is kept in an ejected state by the cam structure 62. At this point, the cam structure 62 forces the neutral wire 644 and the live wire at the corresponding position to eject outward, extending into the wire groove 46 of the track 4. There, they respectively contact the neutral wire metal strip 42 and the target live wire metal strip 41 in the track 4, forming an electrical connection path and enabling power collection.

[0039] It should be understood that in this embodiment, the one power-off position and the three power-on positions are arranged in a circular array, and the limit structure 63 is closely integrated with the position layout of the high-voltage switch 6. When the high-voltage switch 6 is switched to the power-off position or the other three power-on positions, no matter which power-on position it is in, the telescopic limit block 631 or the first fixed limit block 632 is always in an extended state and cooperates with the anti-slip position 44 in the track 4. When the cam structure 62 drives the neutral wire 644 and the corresponding live wire to pop out to take power, if the telescopic limit block 631 is not extended in the current state, it indicates that the first fixed limit block 632 has been extended. It will extend outward under the triggering of the gear switching action, and take turns with the first fixed limit block 632 to firmly lock the drive power box, offsetting the tendency of the drive power box to leave the track 4 due to factors such as its own weight, and ensuring that the drive power box is stably fixed on the track 4 when taking power.

[0040] When the driving power box needs to be removed, pull the driving power box downward with force. The telescopic limit block 631 is squeezed by the track 4 and automatically retracts to avoid the problem by overcoming the resistance of the elastic structure. This releases the limit constraint on the driving power box and allows the driving power box to smoothly detach from the track 4.

[0041] The track-type drive power supply box provided by the present invention makes a creative improvement to the high-voltage switch 6, integrating the three functions of power supply, gear adjustment and track locking 4 into one, which has the following advantages:

[0042] 1. The independent phase adjustment mechanism is eliminated, simplifying the product structure. By arranging the neutral wire taking-in wire 644 and the live wire taking-in wire beside the cam structure 62, the first rotating seat 61 drives the cam structure 62 to control the ejection and retraction of the power taking part. The overall structure is more compact, reducing the space occupied in the power box body 1. This optimizes the space utilization of the product and significantly shortens the overall length of the driving power box, which is conducive to the expansion of the product in appearance design and installation and use scenarios, and enhances the market competitiveness of the product.

[0043] 2. The original elastic limit ridge is removed and its limiting function is integrated into the high-voltage switch 6. Whether in the installation state of the power-off position or the working state of the power-on position, the telescopic limit block 631 or the first fixed limit block 632 always cooperates with the outer surface of the track 4 to limit the position. This full-state limit design can effectively cope with the external forces exerted on the power supply box under different working conditions, ensuring that the power supply box and the track 4 always maintain a stable connection, avoiding safety hazards such as circuit interruption and equipment falling due to loose connections, significantly improving the reliability and safety of the product, and further shortening the length of the power supply box, improving the product's compactness and space utilization.

[0044] Specifically, the three live wire taking wires are the first live wire taking wire 641, the second live wire taking wire 642 and the third live wire taking wire 643. The cam structure 62 includes a first cam 621, a second cam 622 and a third cam 623 connected in sequence from top to bottom. The first live wire taking wire 641 and the second live wire taking wire 642 are located beside the first cam 621. The first cam 621 is used to drive the first live wire taking wire 641 and the second live wire taking wire 642 to pop out one by one. The third live wire taking wire 643 is located beside the second cam 622. The second cam 622 is used to drive the third live wire taking wire 643 to pop out. The neutral wire taking wire 644 is located beside the third cam 623. The third cam 623 is used to drive the neutral wire taking wire 644 to pop out.

[0045] When the high-voltage switch 6 is working, the first rotating seat 61 is rotated to switch between the power-off position and the three power-on positions. When the first rotating seat 61 rotates, it will drive the first cam 621, the second cam 622 and the third cam 623 to rotate synchronously. When switching to the first power-on position, the contour shape of the first cam 621 changes, and its special structure applies a force to the first live wire taking wire 641 on the side, driving the first live wire taking wire 641 to pop out. At this time, the third cam 623 also rotates synchronously, and its contour displacement drives the neutral wire taking wire 644 to pop out. The popped-out first live wire taking wire 641 and the neutral wire taking wire 644 respectively contact the corresponding live wire metal strip 41 and neutral wire metal strip 42 in the track 4, establishing a high-voltage connection and realizing power taking.

[0046] When the first rotating seat 61 switches to the second power connection gear, the first cam 621 continues to rotate. After losing the force of the first cam 621, the first live wire taking wire 641 will elastically deform and retract to reset, disconnecting from the corresponding live wire metal strip 41. Then the contour of the first cam 621 is displaced to apply force to the second live wire taking wire 642, driving the second live wire taking wire 642 to pop out. At the same time, the third cam 623 maintains its action on the neutral wire taking wire 644, so that the neutral wire taking wire 644 continues to contact the neutral wire metal strip 42. At this time, the second live wire taking wire 642 and the neutral wire taking wire 644 cooperate to complete power collection.

[0047] When the first rotating seat 61 switches to the third power-connecting gear, the first cam 621 continues to rotate, and the first cam 621 cancels the force applied to the first live wire taking wire 641 and the second live wire taking wire 642. The first live wire taking wire 641 and the second live wire taking wire 642 are both in a retracted reset state. After the second cam 622 rotates, its contour is displaced to apply force to the third live wire taking wire 643 on the side, driving the third live wire taking wire 643 to pop out outward. Similarly, the third cam 623 maintains its effect on the neutral wire taking wire 644. The third live wire taking wire 643 and the neutral wire taking wire 644 contact the corresponding metal strips in the track 4 to achieve power collection.

[0048] When the first rotating seat 61 is in the power-off position, all cams no longer exert outward force on the power-taking component. Under the action of the power-taking component's own restoring force, the first live wire taking wire 641, the second live wire taking wire 642, the third live wire taking wire 643 and the neutral wire taking wire 644 all retract inward, breaking away from contact with the metal strip in the track 4, and disconnecting the high-voltage connection.

[0049] Specifically, each of the first and second cams 621 and 622 is provided with an ejection protrusion 624. The third cam 623 includes a central circular body and an ejection protrusion 625 concentrically disposed around the central circular body. The ejection protrusion 625 is a superior arc structure. In a top view, the angle between the ejection protrusion 624 of the first and second cams 621 and 622 is 90°, and the ejection protrusion 624 of the second cam 622 does not overlap with the ejection protrusion 625. The ejection protrusions 624 of the first and second cams 621 and 622 precisely focus force on a specific live wire, ensuring that only one live wire is ejected at a time when switching gears, preventing multiple live wires from being ejected simultaneously and causing short circuits and other faults. The superior arc structure of the third cam 623 pushes out the circular protrusion 625, which can continuously and stably apply force to the neutral wire taking wire 644, ensuring that the neutral wire taking wire 644 can reliably contact the neutral wire metal strip 42 under all power connection positions, thereby improving the stability and reliability of the entire high-voltage switch 6.

[0050] The live wire and neutral wire 644 are specifically copper wire structures, which increase the contact area with the high-voltage metal strip compared to the copper sheet structure. In the actual power supply process, the wire body can fit with the metal strip in a circumferential or multi-point contact manner, effectively reducing the risk of power failure due to poor contact. Even if the track 4 has a certain degree of wear and deformation, or there is a slight offset during installation, the copper wire can ensure a good electrical connection with the high-voltage metal strip by virtue of its large contact area, stably transmit current, and provide more reliable power guarantee for the normal operation of the track light, reducing the problem of lighting interruption due to power supply failure.

[0051] As a preferred embodiment, the output ends of the neutral wire 644 and the live wire are connected to the circuit assembly 2 through a conductive clamp 651, and the input end forms an arc-shaped power-taking hook 652. The arc-shaped power-taking hook 652 can closely fit the surface contour of the high-voltage metal strip of the track 4, increase the contact area, reduce the contact resistance, and reduce the power transmission loss. At the same time, the arc-shaped structure provides a certain elastic clamping force. Even if the track 4 is slightly deformed or vibrated due to external force, it can ensure that the power-taking component and the metal strip are in continuous and stable contact, avoiding power outages or current fluctuations caused by poor contact, and providing a stable and reliable power supply for the track light. The conductive clamp 651 is connected to the circuit board of the circuit assembly 2, and a stable connection between the wire and the circuit board is achieved by mechanical clamping. Compared with the traditional welding method, it effectively prevents the loosening and falling off of the solder joints caused by vibration, thermal expansion and contraction, further ensuring the stable operation of the circuit and reducing the probability of equipment failure.

[0052] Preferably, the first live wire 641 and the second live wire 642 are arranged on the left and right sides, the third live wire 643 is located below the first live wire 641, and the neutral wire 644 is located below the second live wire 642. The first live wire 641, the second live wire 642, the third live wire 643, and the neutral wire 644 are clamped on the wire holder 653 and their routing is adjusted so that the output sections of the first live wire 641, the second live wire 642, the third live wire 643, and the neutral wire 644 are led out straight and arranged in an upward and downward manner. Compared to traditional chaotic or flat wiring methods, this significantly reduces the space occupied by the power supply components and wiring within the power box. The compact spatial layout not only leaves more space for the installation and layout of other electronic components in the power box, facilitating the optimization of circuit design, but also provides the possibility for the driving power box to achieve miniaturization and lightweight design, so that it can better adapt to installation scenarios with limited space and enhance the product's competitiveness in the market.

[0053] The wire holder 653 is actually a combination of multiple layers of blocks. The layers can be connected by snaps, ultrasonic welding, and pins. The layers are provided with wiring grooves that guide the three live wires and the neutral wire 644 to turn to the flat arrangement of the wiring.

[0054] Specifically, the first rotating seat 61 includes an upper half body 611 and a lower half body 612 connected to each other. The cam structure 62 is disposed on the upper half body 611, and the first fixed stop block 632 is disposed on the outer circumference of the lower half body 612. The first rotating seat 61 adopts a split design with the upper half body 611 and the lower half body 612, which can be connected by ultrasonic welding or a snap connection method, so that the cam structure 62 and the first fixed stop block 632 are spatially separated. The cam structure 62 is disposed on the upper half body 611, making full use of the space above it to realize the control function of the power supply component; the first fixed stop block 632 is disposed on the outer circumference of the lower half body 612, and cooperates with the slide groove 633 and the telescopic stop block 631 at the top of the lower half body 612 to form a three-dimensional stop structure. This layout avoids the stacking of components in the horizontal direction. Compared with the traditional integrated design, it greatly reduces the space waste inside the drive power box, making the overall structure more compact.

[0055] Furthermore, a slot 633 is formed at the top of the lower half body 612 to guide the extension and retraction of the telescopic limit block 631. The backs of the two telescopic limit blocks 631 are connected by a first spring 634. The slot 633 provides a precise motion track for the telescopic limit blocks 631, effectively limiting their deviation and shaking during the telescopic extension process, ensuring that they accurately cooperate with the track 4 to achieve their limiting function. Furthermore, the backs of the two telescopic limit blocks 631 are connected by a first spring 634. The stable elastic force provided by the first spring 634 not only ensures that the telescopic limit blocks 631 are reliably extended and limited in normal operation, but also allows them to quickly return to their original position after being squeezed and retracted by external forces. Furthermore, the first spring 634 acts as a buffer and shock absorber during frequent telescopic movements, reducing collision wear between various components. This significantly improves the structural reliability and service life of the limit structure 63 and, ultimately, the entire drive power box, and reduces the probability of failures due to structural instability.

[0056] The edges of the clamping end of the telescopic limit block 631 are chamfered to form an assisting bevel 6311. During the installation of the drive power box, the assisting bevel 6311 of the telescopic limit block 631 is the first to contact the track 4. Compared with the traditional right-angled edges, the bevel structure can decompose the squeezing force of the track 4 on the telescopic limit block 631 into a component perpendicular to the bevel and a component along the direction of the bevel. The component along the direction of the bevel will guide the telescopic limit block 631 to retract more smoothly, greatly reducing the friction resistance between the telescopic limit block 631 and the track 4. This design makes the process of inserting the drive power box into the track 4 easier and smoother, reduces the jamming phenomenon during the installation process, effectively improves the assembly efficiency, reduces the labor intensity of manual installation, and also reduces the risk of component damage due to excessive installation resistance.

[0057] When removing the power supply box, pulling it downward with force will cause the telescopic limit block 631 to contact the track 4 again. The assisting inclined surface 6311 can prevent sharp collisions and scratches between the clamping end of the telescopic limit block 631 and the track 4. Under the guidance of the assisting inclined surface 6311, the impact force on the telescopic limit block 631 during retraction is buffered and dispersed, effectively reducing the wear and scratches on the surface of the telescopic limit block 631 and the track 4, and protecting the structural integrity of both. During long-term use, this design can significantly extend the service life of the power supply box and the track 4, reduce the maintenance and replacement costs of the equipment, and improve the overall reliability of the product.

[0058] See Figure 5 As shown, a first snap ring 615 is provided at the bottom of the lower half seat 612. During the installation process, the first snap ring 615 can be quickly and accurately snapped into the installation position in the power box body 1, effectively preventing the first rotating seat 61 from being offset or misaligned in the axial direction, and ensuring that the relative position of the first rotating seat 61 and the power box body 1 remains unchanged. A shift mark 614 is provided on the first snap ring 615 and a first rotating slot 613 is opened. The shift mark 614 on the first snap ring 615 cooperates with the gear number 11 on the power box body 1 to form a clear and intuitive gear indication. See Figure 7 As shown, gear 0 is the power-off gear, while gears 1, 2, and 3 are all power-on gears. When adjusting the high-voltage switch 6, the user can quickly and accurately determine the current gear and the direction to switch by observing the correspondence between the shift mark 614 and the gear number 11, thus avoiding power failure or circuit failure due to misoperation. This design reduces the user's professional knowledge requirements, allowing ordinary users to easily complete the gear adjustment operation, improving the product's usability and user experience. Using a suitable tool (such as a screwdriver, hexagonal wrench, etc.) to insert into the first rotating slot 613 can directly drive the first retaining ring 615 to rotate, thereby driving the first rotating seat 61 to switch gears.

[0059] The conductive copper sheet of the existing weak current switch adopts an L-shaped structure, which includes a power extraction sheet extending horizontally from a rotating seat and a bent arm located in the rotating seat. Figure 9 As shown, since the conductive metal strips in the track 4 are separated by transverse groove lines 45 and are hidden deep in the wire groove 46 between the two transverse groove lines 45, the extended power strip 841 needs to extend into the wire groove 46 to electrically connect with the weak-current metal strip 43. However, the gap in the wire groove 46 is narrow, resulting in a power strip thickness of only about 0.3mm. During the process of rotating and extending into the wire groove 46, it is very easy to touch the transverse groove line 45. In addition, because the conductive copper sheet has a thin L-shaped structure, once the power strip touches the transverse groove line 45, it is easy to unilaterally bend upward or downward and deform, unable to maintain a straight state. Ultimately, the conductive copper sheet cannot form an effective electrical connection with the weak-current metal strip 43, affecting the normal signal control function of the track light and reducing the reliability and user experience of the product.

[0060] To this end, we have made creative improvements to the weak current switch 8. Please participate. Figures 10 to 13 The weak-current switch 8 includes a second rotating seat 81 rotatably arranged in the power box body 1, a first conductive piece 82, a second conductive piece 83 and a second fixed limit block 85 arranged on the second rotating seat 81, and the first conductive piece 82 and the second conductive piece 83 are in the shape of a "mountain". The first conductive piece 82 and the second conductive piece 83 both include an extended power-taking piece 841 extending horizontally from the second rotating seat 81 and two stable bent arms 842 arranged in the second rotating seat 81 and respectively arranged on the upper and lower sides of the extended power-taking piece 841, and one of the stable bent arms 842 is formed with a power-connecting piece 8423 extending from the second rotating seat 81.

[0061] After the power box body 1 slides along the track 4 to the appropriate position, the second rotating seat 81 is rotated, causing the second fixed stop block 85 to rotate and engage within the track 4, thereby securing the low-current switch 8 to the track 4. The power box body 1 is provided with an anti-reverse mounting member 12. This mounting member 12 cooperates with the braid on the track 4 to ensure that the power box is installed on the track in the correct position. The number and location of the mounting member 12 are not specifically limited. Simultaneously, the extended power strip 841 of the first and second conductive plates 82, 83 moves toward the low-current metal strip 43 deep within the internal wire trough 46 of the track 4 (between the two transverse trough lines 45). During the process of extending into the wire trough 46, if the extended power strip 841 touches the transverse trough line 45, the first and second conductive plates 82, 83 are provided with stabilizing arms 842 located above and below the extended power strip 841. These stabilizing arms 842 form a triangular support and restraint structure, enhancing the structural rigidity. When the epitaxial power-taking sheet 841 is subjected to lateral stress from the transverse slot line 45, the stable bent arms 842 on the upper and lower sides can offset the lateral stress, preventing the epitaxial power-taking sheet 841 from undergoing unilateral bending deformation upward or downward due to unilateral force, thereby maintaining the straight posture of the epitaxial power-taking sheet 841, ensuring that it can smoothly cut into the wire slot 46, achieve electrical connection with the conductive metal strip, and realize stable conduction of the weak current signal of the track light.

[0062] The low-voltage switch 8 has a unique design of a "mountain"-shaped first conductive plate 82 and a second conductive plate 83 with upper and lower stabilizing arms 842. Even if it touches the horizontal slot line 45 during the power-taking process, the stabilizing arms 842 can disperse the lateral force and keep the extended power-taking plate 841 straight. This greatly improves the stability of the electrical connection with the low-voltage metal strip 43, ensures the normal operation of the track light signal control function, avoids problems such as light flickering and control failure caused by unstable electrical connection, and significantly improves the reliability of the product.

[0063] Furthermore, the second rotating seat 81 includes a main seat body 811 and a side cover 812. The second rotating seat 81 adopts a split structure of the main seat body 811 and the side cover 812. When installing the first conductive sheet 82, the second conductive sheet 83 and the second fixed limit block 85, each component can be placed in the installation cavity 813 of the main seat body 811 first, and then sealed and fixed by the side cover 812, which simplifies the installation process. Two installation cavities 813 arranged on the left and right are provided in the main seat body 811, providing independent and stable installation space for the first conductive sheet 82 and the second conductive sheet 83. The two installation cavities 813 are separated by a partition wall 814. The partition wall 814 can limit the lateral movement of the conductive sheet in the installation cavity 813 to prevent the conductive sheets from colliding or shifting with each other due to external forces.

[0064] Each of the stabilizing arms 842 includes a diagonal support piece 8421 connected to one end of the extended power-taking piece 841 and a bent piece 8422 connected to the diagonal support, wherein the bent piece 8422 rests against the partition wall 814. Through this arrangement, the external force exerted on the extended power-taking piece 841 during its insertion into the wire trough 46 can be dispersed and transmitted to the main body of the second rotating seat 81 through the stabilizing arm 842. The bent piece 8422 rests against the partition wall 814, which provides reverse support for the bent piece 8422, forming a stable triangular support structure. This mechanical design ensures that even if the extended power-taking piece 841 encounters a large lateral force in the narrow wire trough 46, such as when it touches the transverse trough line 45, it can rely on the support of the stabilizing arm 842 to effectively resist deformation, ensuring that the extended power-taking piece 841 always remains straight, firmly achieving electrical connection with the weak-current metal strip 43, and significantly improving the durability and connection reliability of the weak-current switch 8.

[0065] The specifications of different track 4 products are not uniform. The wire grooves 46 of different track 4 products may have a height difference of about 1mm, and the extended power-taking sheet 841 is as thin as a blade. When inserted deep into the wire groove 46, it is easy to get stuck once it hits the transverse groove line 45. Even if you squeeze it hard, it is difficult to move due to its thin and fragile structure. For this reason, protrusions 844 are provided on the upper and lower end faces of the extended power-taking sheet 841 near the free end. The protrusions 844 can be specifically round and smooth rivet points. By reducing friction and optimizing the force mode, damage to the power-taking sheet and the transverse groove line 45 due to excessive force is avoided. When encountering a jam, only a small external force needs to be applied to squeeze hard. The protrusion 844 greatly reduces the friction in the form of point contact, which sharply reduces the resistance originally caused by large-area friction. At this time, the protrusion 844 can assist the extended power-taking piece 841 to easily break through the jam and smoothly slide into the deep of the wire groove 46 to connect with the weak-current metal strip 43. On the one hand, it effectively avoids installation failures caused by jamming and significantly improves the success rate of power connection; on the other hand, it can adapt to more track 4 products and improve the product competitiveness of the driving power box.

[0066] It should be noted that the shape of the protrusion 844 is not limited to a circle, and can also be any protrusion shape such as an ellipse, a square, a rectangle, a convex point, etc.

[0067] Since the epitaxial power-taking piece 841 may get stuck when its upper or lower end face contacts the transverse groove line 45 during the process of being inserted into the wire groove 46. Circular smooth protrusions 844 are provided on both the upper and lower end faces to form a two-way protection mechanism. Regardless of whether the upper or lower end face of the epitaxial power-taking piece 841 contacts the transverse groove line 45 first and causes a jam when extending into the wire groove 46, the protrusion 844 can play a role in reducing friction and assisting in guidance. The protrusions 844 in two directions work together to further reduce the probability of getting stuck, ensuring that the epitaxial power-taking piece 841 can easily break through obstacles when encountering them and smoothly connect to the weak-current metal strip 43. Compared with only setting the protrusion 844 on one side, the smoothness of the installation process and the overall installation success rate are greatly improved.

[0068] The bottom of the second rotating seat 81 is formed with two second retaining rings 87 spaced horizontally above and below. During installation, the second retaining rings 87 can quickly and accurately snap into place within the power supply box, effectively preventing axial displacement or misalignment of the second rotating seat 81 and ensuring that the relative position of the second rotating seat 81 and the power supply box remains fixed. The bottom of the bottom second retaining ring 87 is provided with a second rotation slot 815. A suitable tool (such as a screwdriver, hexagonal wrench, etc.) inserted into the first rotation slot 613 directly drives the first rotating seat 61 to rotate and switch the weak current power supply.

[0069] The circuit assembly 2 includes a circuit board and a communication unit mounted on the circuit board. The communication unit is used for remote data communication. In one embodiment, the communication unit may be, for example, a Bluetooth adapter unit or a Wi-Fi adapter unit. In actual use, the communication unit establishes a remote communication connection with a terminal device. The terminal device sends an operating instruction to the communication unit, which then feeds the operating instruction back to the circuit board. The circuit board then controls the lighting fixture to perform the corresponding operation based on the operating instruction.

[0070] The top of the lamp connector 3 is movably embedded in the connector mounting cavity in the power box body 1, and a flat contact is connected to one side of it. The circuit board is provided inside the power box body 1, and a V-shaped elastic contact is connected to the circuit board. The V-shaped elastic contact is movably abutted against the flat contact. The bottom of the box body is slidably connected to a shift block, and a first plug block is connected above the shift block. A first through hole is provided on one side of the connector mounting cavity, and a second through hole is provided above the first through hole. The V-shaped elastic contact passes through the second through hole, and the first plug block movably passes through the first through hole. A first slot is provided on one side of the lamp connector 3, and the first plug block is movably plugged into the first slot.

[0071] By moving the first plug-in block through the first through hole, the first plug-in block is inserted into the first slot, thereby realizing quick locking of the lamp connector 3. At this time, the V-shaped elastic contact piece abuts against the flat contact piece, and the driving circuit board and the lamp connector 3 can be conductive without wiring. On the contrary, the lamp connector 3 can be quickly pulled out, which is convenient for users to install and disassemble the lamp connector 3, thereby improving the convenience of use and reducing the cost of use.

[0072] In order to facilitate the improvement of the installation stability of the lamp connector 3 and to improve the convenience of use without the need for toggling, in this embodiment, preferably, a second spring is provided inside the power box body 1, one end of the second spring is connected to a second plug, the second plug is provided with a first inclined surface on the upper side of the end away from the second spring, and a second inclined surface on the lower side of the end away from the second spring, a third through hole is provided on the other side of the connector installation cavity, the second plug movably passes through the third through hole, a second slot is provided on the other side of the lamp connector 3, and the second plug is movably inserted into the second slot.

[0073] The purpose is that when the lamp connector 3 is inserted into the connector mounting cavity, the lamp connector 3 pushes the second plug out of the connector mounting cavity through the guidance of the second inclined surface. When the lamp connector 3 is fully inserted into the connector mounting cavity, the elastic force of the second spring allows the second plug to pass through the third through hole and then be inserted into the second slot, thereby limiting and locking the lamp connector 3, improving the installation stability of the lamp connector 3, and eliminating the need to move the second plug, thereby improving the convenience of use. When the lamp connector 3 is pulled out from the mounting cavity 813, the lamp connector 3 pushes the second plug out of the mounting cavity 813 through the guidance of the first inclined surface, without the need to move the second plug, thereby improving the convenience of disassembly of the lamp connector 3.
