Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of track lights, and particularly to an orbital drive power supply box. Background Art
[0002] In the modern lighting field, track lights are widely used in commercial spaces, exhibition halls, etc. due to their advantages such as convenient installation and flexible position adjustment. A track light generally consists of a drive power supply box (power converter) and a lamp body connected to its bottom. Its power supply depends on the conductive metal strips on both sides inside the track. One part is a strong - power metal strip responsible for providing strong voltages such as 110V / 220V / 380V, and the other part is a weak - power metal strip responsible for providing weak voltages such as 10V / 12V / 24V / 36V. The drive power supply box is provided with corresponding lamp connectors, a strong - power extraction switch, and a weak - power extraction switch.
[0003] The current drive power supply box is difficult to improve and shorten the overall length of the drive power supply box, which has an adverse impact on improving the market competitiveness of products. The specific reasons are as follows: Taking the reference of the existing patent (CN216307724U) as an example, 1. The existing strong - power extraction switch usually includes a rail power connector and a phase - adjustment mechanism. This power - extraction method with the fully - opened rotating conductive sheet has obvious defects. On the one hand, it must cooperate with the phase - adjustment mechanism to achieve effective power extraction. The phase - adjustment mechanism has a large number of components, which is not conducive to reducing manufacturing costs and improving production efficiency. On the other hand, the rail power connector and the electrode - adjustment mechanism are generally arranged side - by - side left and right in the power supply box body, occupying a very large space, which is the main reason for the difficulty in shortening the length of the drive power supply box. 2. In order to prevent the drive power supply box from detaching from the track under its own weight after being installed on the track, an elastic limiting convex is generally provided at a position near the end of the side wall of the power supply box body. The elastic limiting convex cooperates with the anti - detachment position in the track to achieve anti - detachment. At the same time, although the rail power connector of its strong - power extraction switch is configured with a limiting structure, the limiting structure can only extend outwards simultaneously when the power - extraction part extends out for power extraction, further ensuring that the drive power supply box will not detach from the track during the working state. However, setting the elastic limiting convex on the power supply box body will occupy a part of the length of the drive power supply box.
[0004] It can be seen that the existing technology still needs to be improved. Summary of the Invention
[0005] In view of the above - mentioned deficiencies of the existing technology, the purpose of the present invention is to provide an orbital drive power supply box, aiming to improve and reduce the length dimension of the drive power supply box and enhance the market competitiveness.

[0008] As a further improvement of the above technical solution, there is a top ejection tip on both the first cam and the second cam; the third cam includes a central circular body and a top ejection circular convex concentrically arranged on the periphery of the central circular body. The top ejection circular convex is a major arc circular structure; in the top view projection, the included angle between the top ejection tips of the first cam and the second cam is 90°, and the top ejection tip of the second cam does not overlap with the top ejection circular convex.
[0009] As a further improvement of the above technical solution, the first rotating seat includes an upper half seat body and a lower half seat body connected to each other.

The backs of the two telescopic limiting blocks are connected by a first spring.
[0010] As a further improvement of the above technical solution, the edge of the clamping end of the telescopic limiting block is chamfered to form an assisting moving inclined surface.
[0011] 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 component through a conductive clip, and the input ends form arc-shaped power-taking hooks.

Specific implementation mode
[0031] The present invention provides an orbital drive power supply box. To make the purpose, technical solution and effects of the present invention clearer and more definite, the following further elaborates on the present invention with reference to the accompanying drawings and by way of examples. It should be understood that the specific examples described herein are only used to explain the present invention and are not used to limit the protection scope of the present invention.
[0032] Please refer to Figures 1 to 8, the present invention provides an orbital drive power supply box, which includes a power supply box body 1, a circuit component 2 arranged in the power supply box body 1, a lamp connector 3, a weak power extraction switch 8, and a strong power extraction switch 6; the output end of the circuit component 2 is electrically connected to the lamp connector 3, and the input end of the circuit component 2 is electrically connected to the weak power extraction switch 8 and the strong power extraction switch 6 respectively; the strong power extraction switch 6 includes 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 wire extraction wire 644 and three live wire extraction wires arranged beside the cam structure 62. The first rotating seat 61 rotates to form a power-off gear and three power-on gears. The first rotating seat 61 is used to drive the cam structure 62 to rotate. When in any power-on gear, the cam structure 62 drives the neutral wire extraction wire 644 and one of the live wire extraction wires to pop outwards; when in the power-off gear, the neutral wire extraction wire 644 and all the live wire extraction wires retract inwards; 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.
[0033] Before installing the drive power supply box, the strong power extraction switch 6 needs to be adjusted to the power-off gear. At this time, the neutral wire extraction wire 644 and all the live wire extraction wires retract into the power supply box body 1, and the two telescopic limiting blocks 631 are in the extended state. When the drive power supply box is inserted into the track 4 from bottom to top, the extended telescopic limiting blocks 631 will contact the track 4. Under the extrusion of the track 4, the telescopic limiting blocks 631 automatically retract against the resistance of the internal elastic structure, providing a clearance space for the insertion of the drive power supply box to ensure that the drive power supply box can be smoothly inserted into the track 4. After the drive power supply box is completely inserted in place, the telescopic limiting blocks 631 that lose the extrusion of the track 4 extend again under the restoring force of the elastic structure and closely cooperate with the anti-detachment clamping position 44 in the track 4 to prevent the drive power supply box from falling off the track 4 during use, causing damage to the drive power supply box and the lamp and personal injury accidents. When the first rotating seat 61 is in the power-off gear, the shape of the cam structure 62 does not exert a pressing effect on the neutral wire extraction wire 644 and the live wire extraction wires. The neutral wire extraction wire 644 and the live wire extraction wires retract inwards and reset to the natural state, completely separating from the strong power metal strip in the track 4 and cutting off the power connection to ensure safe power-off.
[0034] When the first rotating seat 61 rotates to any power-connection gear, the cam structure 62 rotates synchronously with the first rotating seat 61, and the change in the shape of its outer peripheral contour will generate a mechanical thrust on the live wire taking wire at the corresponding position, while the neutral wire taking wire 644 is always kept in a pop-up state by the cam structure 62. At this time, the cam structure 62 drives the neutral wire taking wire 644 and the live wire taking wire at the corresponding gear to pop out of the outer shape, extend into the wire groove 46 of the track 4, and 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 to achieve power collection.
[0035] 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 combined with the position layout of the high-voltage switch 6. In the process of switching the high-voltage switch 6 to the power-off position or the other three power-on positions, no matter in any power-on position, there is always a telescopic limit block 631 or a first fixed limit block 632 in an extended state to cooperate with the anti-slip position 44 in the track 4. When the cam structure 62 drives the neutral line wire 644 and the corresponding live line 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, and 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 deviate from 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 in the power-taking working state.
[0036] When the driving power box needs to be removed, pull the driving power box downward with force, and the telescopic limit block 631 is squeezed by the track 4, and again overcomes the resistance of the elastic structure and automatically retracts to avoid, thereby releasing the limit constraint on the driving power box, allowing the driving power box to smoothly detach from the track 4.
[0037] The track-type driving power supply box provided by the present invention makes a creative improvement on the high-voltage switch 6, integrating the three functions of power supply, gear adjustment and locking track 4 into one, and has the following advantages: 1. The independent phase adjustment mechanism is cancelled, which simplifies the product structure. By arranging the neutral wire taking wire 644 and the live wire taking wire beside the cam structure 62, the cam structure 62 is driven by the first rotating seat 61 to control the ejection and retraction of the power taking part. The overall structure is more compact, and the space occupied in the power box body 1 is reduced. This optimizes the space utilization of the product and significantly shortens the overall length of the driving power box, which is beneficial to the expansion of the product in appearance design and installation and use scenarios, and enhances the market competitiveness of the product.
[0038] 2. Cancel the original elastic limiting convex setting, and incorporate the limiting function of the original elastic limiting convex into the strong power taking switch 6. Whether in the installation state of the power-off gear or the working state of the power-on gear, there is always a telescopic limiting block 631 or a first fixed limiting block 632 that cooperates with the outer surface of the track 4 for limiting. This full-state limiting design can effectively cope with the external forces suffered by the drive power supply box under different working conditions, ensure that the drive power supply box is always stably connected to the track 4, and avoid safety hazards such as circuit interruption and equipment dropping caused by loose connection, significantly improving the reliability and safety of the product. It also further shortens the length of the drive power supply box, improving the compactness and space utilization rate of the product.
[0039] 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 that are 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 outwards 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 outwards. 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 outwards.
[0040] When the strong power taking switch 6 works, it switches between the power-off gear and three power-on gears by rotating the first rotating seat 61. 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 gear, the contour shape of the first cam 621 changes, and its special structure exerts a force on the first live wire taking wire 641 beside it, driving the first live wire taking wire 641 to pop outwards. At this time, the third cam 623 also rotates synchronously, and its contour displacement drives the neutral wire taking wire 644 to pop outwards. The popped-out first live wire taking wire 641 and neutral wire taking wire 644 respectively contact the corresponding live wire metal strip 41 and neutral wire metal strip 42 in the track 4 to establish a strong power connection and achieve power taking.
[0041] When the first rotating seat 61 switches to the second power connection gear position, the first cam 621 continues to rotate. After the first live wire extraction wire 641 loses the acting force of the first cam 621, it will elastically deform and retract to its original position, disconnecting the connection with the corresponding live wire metal strip 41. Then, the contour displacement of the first cam 621 applies an acting force to the second live wire extraction wire 642, driving the second live wire extraction wire 642 to pop outwards. At the same time, the third cam 623 maintains its action on the neutral wire extraction wire 644, keeping the neutral wire extraction wire 644 in continuous contact with the neutral wire metal strip 42. At this time, the second live wire extraction wire 642 and the neutral wire extraction wire 644 cooperate to complete power extraction.
[0042] When the first rotating seat 61 switches to the third power connection gear position, the first cam 621 continues to rotate. The first cam 621 cancels the acting forces applied to the first live wire extraction wire 641 and the second live wire extraction wire 642. Both the first live wire extraction wire 641 and the second live wire extraction wire 642 are in the state of retracting and resetting. After the second cam 622 rotates, its contour displacement applies an acting force to the adjacent third live wire extraction wire 643, driving the third live wire extraction wire 643 to pop outwards. Similarly, the third cam 623 maintains its action on the neutral wire extraction wire 644. The third live wire extraction wire 643 and the neutral wire extraction wire 644 come into contact with the corresponding metal strips in the track 4 to achieve power extraction.
[0043] When the first rotating seat 61 is in the power-off gear position, all the cams no longer apply an outward acting force to the power extraction components. Under the action of the self-restoring force of the power extraction components, the first live wire extraction wire 641, the second live wire extraction wire 642, the third live wire extraction wire 643, and the neutral wire extraction wire 644 all retract inwards, disengaging from the contact with the metal strips in the track 4 and disconnecting the strong electricity connection.
[0044] Specifically, a jacking tip 624 is provided on both the first cam 621 and the second cam 622; the third cam 623 includes a central circular body and a jacking convex circle 625 concentrically arranged on the periphery of the central circular body. The jacking convex circle 625 is a major arc circular structure; in the top view projection, the included angle between the jacking tips 624 of the first cam 621 and the second cam 622 is 90°, and the jacking tip 624 of the second cam 622 does not overlap with the jacking convex circle 625. The jacking tip 624 structures of the first cam 621 and the second cam 622 can accurately concentrate the acting force on a specific live wire extraction wire. When switching the gear positions, it ensures that only the corresponding live wire extraction wire is jacked out each time, avoiding faults such as short circuits caused by multiple live wire extraction wires popping out simultaneously. The major arc circular structure jacking convex circle 625 of the third cam 623 can continuously and stably apply an acting force to the neutral wire extraction wire 644, ensuring that the neutral wire extraction wire 644 can reliably contact the neutral wire metal strip 42 in each power connection gear position, thereby improving the stability and reliability of the entire strong electricity switch 6.
[0045] The live wire extraction wire and the neutral wire extraction wire 644 are specifically made of copper wire. Compared with the copper sheet structure, the contact area with the strong electric metal strip is increased. During the actual power extraction process, the wire body can fit with the metal strip in a surrounding or multi-point contact manner, effectively reducing the risk of power failure caused by poor contact. Even if the track 4 has a certain degree of wear, deformation, or a slight deviation occurs during the installation process, the copper wire can ensure good electrical connection with the strong electric metal strip due to its large contact area, stably transmit current, provide more reliable power supply for the normal operation of the track light, and reduce the problem of lighting interruption caused by power extraction failure.
[0046] As a preferred implementation manner, the output ends of the neutral wire extraction wire 644 and the live wire extraction wire are connected to the circuit component 2 through the conductive clamping member 651, and the input ends form an arc-shaped power extraction hook 652. The arc-shaped power extraction hook 652 can closely fit the surface contour of the strong electric 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 has a slight deformation or vibration due to external force, it can ensure continuous and stable contact between the power extraction part and the metal strip, avoiding problems such as power failure or current fluctuation caused by poor contact, and providing a stable and reliable power supply for the track light. The conductive clamping member 651 is connected to the circuit board of the circuit component 2, and the wire is firmly connected to the circuit board by mechanical clamping. Compared with the traditional welding method, it effectively prevents the solder joints from loosening and falling off due to factors such as vibration, thermal expansion and contraction, further ensuring the stable operation of the circuit and reducing the probability of equipment failure.
[0047] Preferably, the first live wire extraction wire 641 and the second live wire extraction wire 642 are distributed left and right, the third live wire extraction wire 643 is located below the first live wire extraction wire 641, the neutral wire extraction wire 644 is located below the second live wire extraction wire 642, and the first live wire extraction wire 641, the second live wire extraction wire 642, the third live wire extraction wire 643 and the neutral wire extraction wire 644 are clamped on the wire fixing seat 653 and their wiring directions are adjusted so that the output sections of the first live wire extraction wire 641, the second live wire extraction wire 642, the third live wire extraction wire 643 and the neutral wire extraction wire 644 are straightly led out and arranged at intervals up and down. Compared with the traditional messy or planar wiring method, the space volume occupied by the power extraction part and the wiring in the power supply box is significantly reduced. The compact space layout not only leaves more space for the installation and layout of other electronic components in the power supply box, facilitating the optimization of the circuit design, but also makes it possible to realize the miniaturization and thinness design of the drive power supply box, enabling it to better adapt to the installation scenarios with limited space and enhancing the competitiveness of the product in the market.
[0048] The wire fixing base 653 is actually an assembly composed of multiple layers of blocks. The layers of blocks can be connected by means of snap fasteners, ultrasonic welding, and pins. The layers of blocks are provided with wire grooves for guiding the three live wire pick-up wires and the neutral wire pick-up wire 644 to turn and arrange the wires in a planar manner.
[0049] Specifically, the first rotating seat 61 includes an upper half seat body 611 and a lower half seat body 612 that are connected to each other. The cam structure 62 is arranged on the upper half seat body 611, and the first fixed limit block 632 is arranged on the outer peripheral surface of the lower half seat body 612. The first rotating seat 61 adopts a split design of the upper half seat body 611 and the lower half seat body 612, and can be specifically connected by ultrasonic welding or snap connection to spatially separate and arrange the cam structure 62 and the first fixed limit block 632. The cam structure 62 is arranged on the upper half seat body 611 to make full use of the space above it to realize the control function of the power-taking component; the first fixed limit block 632 is arranged on the outer peripheral surface of the lower half seat body 612 and cooperates with the chute 633 and the telescopic limit block 631 at the top of the lower half seat body 612 to form a three-dimensional limit structure. This layout method avoids the stacking occupation of components in the horizontal direction. Compared with the traditional integrated design, it greatly reduces the space waste inside the drive power supply box and makes the overall structure more compact.
[0050] Furthermore, a chute 633 for guiding the telescopic limit block 631 to extend or retract is opened at the top of the lower half seat body 612. The backs of the two telescopic limit blocks 631 are connected by a first spring 634. The chute 633 provides an accurate movement track for the telescopic limit block 631, effectively restricting the deviation and shaking of the telescopic limit block 631 during the telescopic process and ensuring that it can accurately cooperate with the track 4 to realize the limit function. At the same time, 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 can not only ensure that the telescopic limit block 631 reliably extends and limits in the normal state, but also quickly reset after being squeezed and retracted by an external force, and plays a buffering and shock-absorbing role in frequent telescopic actions, reducing the collision and wear between components, greatly improving the structural reliability and service life of the limit structure 63 and even the entire drive power supply box, and reducing the probability of failures caused by structural instability.
[0051] At the edge of the clamping end of the telescopic limit block 631, a chamfer is formed to form an auxiliary moving inclined plane 6311. During the installation of the drive power supply box, the auxiliary moving inclined plane 6311 of the telescopic limit block 631 first contacts the track 4. Compared with the traditional right-angle edge, the inclined plane structure can decompose the extrusion force of the track 4 on the telescopic limit block 631 into a component force perpendicular to the inclined plane and a component force along the inclined plane direction. The component force along the inclined plane direction will guide the telescopic limit block 631 to retract more smoothly, greatly reducing the frictional resistance between the telescopic limit block 631 and the track 4. This design makes the process of inserting the drive power supply box into the track 4 easier and smoother, reduces the jamming phenomenon during installation, effectively improves the assembly efficiency, reduces the labor intensity of manual installation, and also reduces the risk of component damage caused by excessive installation resistance.
[0052] When disassembling the drive power supply box, pulling down forcefully will cause the telescopic limit block 631 to contact the track 4 again. The auxiliary moving inclined plane 6311 can prevent the clamping end of the telescopic limit block 631 from having sharp collisions and scratches with the track 4. Under the guidance of the auxiliary moving inclined plane 6311, the impact force received by the telescopic limit block 631 during retraction is buffered and dispersed, effectively reducing the wear and scratches on the surfaces 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 drive power supply box and the track 4, reduce the maintenance and replacement costs of the equipment, and improve the overall reliability of the product.
[0053] See Figure 5 As shown, a first snap ring 615 is provided at the bottom of the lower seat body 612. During installation, the first snap ring 615 can quickly and accurately snap into the installation position in the power supply box body 1, effectively preventing the first rotating seat 61 from shifting or misaligning in the axial direction, and ensuring that the relative position of the first rotating seat 61 and the power supply box body 1 remains fixed. A shifting mark 614 is provided on the first snap ring 615 and a first rotating slot 613 is provided. The shifting mark 614 on the first snap ring 615 cooperates with the gear number 11 on the power supply box body 1 to form a clear and intuitive gear indication. See Figure 7 As shown, the 0th gear is the power-off gear, and the 1st, 2nd, and 3rd gears are all power-on gears. When the user adjusts the gear of the strong power switch 6, by observing the correspondence between the shifting mark 614 and the gear number 11, the user can quickly and accurately judge the current gear and the direction to be switched, avoiding power-taking failure or circuit faults caused by misoperation. This design reduces the requirements for the user's professional knowledge, enables ordinary users to easily complete the gear adjustment operation, and improves the usability and user experience of the product. Inserting a suitable tool (such as a screwdriver, hex wrench, etc.) into the first rotating slot 613 can directly drive the first snap ring 615 to rotate, thereby driving the first rotating seat 61 to switch gears.
[0054] The existing conductive copper sheet of the weak-current switch adopts an L-shaped structure, including a power-taking sheet horizontally extending out of the rotating seat and a bent arm located inside the rotating seat. See Figure 9 As shown, since the conductive metal strip in the track 4 is separated by the horizontal extension groove line 45 and is deeply hidden in the groove 46 between the two horizontal extension groove lines 45, the extended power-taking sheet 841 needs to extend into the groove 46 to be electrically connected to the weak-current metal strip 43. However, the gap of the groove 46 is narrow, resulting in the thickness of the power-taking sheet being only about 0.3 mm. During the process of rotating and extending into the groove 46, it is very easy to touch the horizontal extension groove line 45. Also, because the conductive copper sheet has a thin L-shaped structure, once the power-taking sheet touches the horizontal extension groove line 45, it is prone to unilateral bending deformation upwards or downwards and cannot maintain a straight state. Eventually, 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.
[0055] Therefore, a creative improvement is made to the weak-current switch 8. Please refer to Figures 10 to 13 The weak-current switch 8 includes a second rotating seat 81 rotatably arranged in the power supply box body 1, a first conductive sheet 82, a second conductive sheet 83 and a second fixed limiting block 85 arranged on the second rotating seat 81. The first conductive sheet 82 and the second conductive sheet 83 are in a "mountain" shape. The first conductive sheet 82 and the second conductive sheet 83 both include an extended power-taking sheet 841 horizontally extending out of the second rotating seat 81 and two stable bent arms 842 arranged inside the second rotating seat 81 and respectively located on the upper and lower sides of the extended power-taking sheet 841. A power connection sheet 8423 extending out of the second rotating seat 81 is formed on one of the stable bent arms 842.
[0056] After the power supply box body 1 slides along the track 4 and is adjusted to a suitable position, rotate the second rotating seat 81 to make the second fixed limiting block 85 rotate and engage with the track 4, so as to fix the weak-current switch 8 on the track 4. An anti-reverse installation part 12 is provided on the power supply box body 1, and the anti-reverse installation part 12 cooperates with the thorns on the track 4 to ensure that the driving power supply box is installed on the track in the correct posture. The set number and position of the anti-reverse installation part 12 are not specifically limited. At the same time, the extension power-taking pieces 841 of the first conductive sheet 82 and the second conductive sheet 83 move towards the weak-current metal strip 43 deep in the inner wire groove 46 (between the two horizontal extension groove lines 45) of the track 4. During the process of extending into the wire groove 46, if the extension power-taking piece 841 touches the horizontal extension groove line 45, due to the stable bending arms 842 respectively located on the upper and lower sides of the extension power-taking piece 841 of the first conductive sheet 82 and the second conductive sheet 83, the stable bending arms 842 will form a triangular support and constraint structure to improve the structural stiffness of itself. When the extension power-taking piece 841 is subjected to the lateral stress of the horizontal extension groove line 45, the stable bending arms 842 on the upper and lower sides can offset the lateral stress, avoiding the unilateral bending deformation of the extension power-taking piece 841 upward or downward due to unilateral force, so as to maintain the straight posture of the extension power-taking piece 841, ensure its smooth cutting into the wire groove 46, realize the electrical connection with the conductive metal strip, and realize the stable conduction of the weak-current signal of the track light.
[0057] With the unique design of the "mountain"-shaped first conductive sheet 82 and second conductive sheet 83 of the weak-current switch 8 and the stable bending arms 842 on the upper and lower sides, even if it touches the horizontal extension groove line 45 during the power-taking process, it can rely on the dispersion effect of the stable bending arms 842 on the lateral force to maintain the straight state of the extension power-taking piece 841, thus greatly improving the stability of the electrical connection with the weak-current metal strip 43, ensuring the normal operation of the signal control function of the track light, avoiding problems such as lamp flickering and control failure caused by unstable electrical connection, and significantly improving the reliability of the product.
[0058] 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 limiting block 85, the components can be first placed in the installation cavity 813 of the main seat body 811, and then sealed and fixed by the side cover 812, which simplifies the installation process. There are two installation cavities 813 arranged left and right in the main seat body 811, providing an 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, and the partition wall 814 can limit the lateral movement of the conductive sheet in the installation cavity 813, avoiding the mutual collision or displacement of the conductive sheets due to external force.
[0059] Each of the stable bending arms 842 includes a brace piece 8421 connected to one end of the epitaxial power-taking piece 841 and a bending piece 8422 connected to the brace. The bending piece 8422 abuts against the partition wall 814. With such an arrangement, the external force received by the epitaxial power-taking piece 841 during the process of extending into the wire groove 46 can be dispersed and transmitted to the main body of the second rotating seat 81 through the stable bending arm 842. And the bending piece 8422 abuts against the partition wall 814, and the partition wall 814 provides a reverse supporting force for the bending piece 8422, forming a stable triangular support structure. This mechanical design enables the epitaxial power-taking piece 841 to effectively resist deformation by relying on the supporting effect of the stable bending arm 842 even when encountering a large lateral force in the narrow wire groove 46, such as when touching the horizontal extension groove line 45, ensuring that the epitaxial power-taking piece 841 always remains straight, stably realizing the electrical connection with the weak-current metal strip 43, and greatly improving the durability and connection reliability of the weak-current switch 8.
[0060] The specifications of different track 4 products are not unified, and there may be a height difference of about 1 mm in the wire grooves 46 of different track 4 products. The epitaxial power-taking piece 841 is as thin as a blade, and when inserted deep into the wire groove 46, it is easy to get stuck once it touches the horizontal extension groove line 45. Even if forced to squeeze hard, due to its thin and fragile structure, it is very difficult to move. Therefore, protrusions 844 are provided at both the upper and lower end faces of the epitaxial power-taking piece 841 near the free end. The protrusions 844 can specifically be round and smooth rivet points. By reducing the friction force and optimizing the force application mode, the damage to the power-taking piece and the horizontal extension groove line 45 caused by excessive force application is avoided. When encountering jamming, only a small external force needs to be applied to squeeze hard, and the protrusions 844 greatly reduce the friction force in the form of point contact, sharply reducing the resistance force generated by large-area friction. At this time, the protrusions 844 can assist the epitaxial power-taking piece 841 to easily break through the jamming and smoothly slide deep into the wire groove 46 to connect with the weak-current metal strip 43. On the one hand, it effectively avoids the installation failure caused by jamming and significantly improves the success rate of the power-taking connection; on the other hand, it can adapt to more track 4 products and improve the product competitiveness of the drive power supply box.
[0061] It should be noted that the shape of the protrusions 844 is not limited to round, and can also be any protruding shape such as oval, square, rectangular, convex point, etc.
[0062] During the insertion of the extension power-taking piece 841 into the wire slot 46, jamming may occur when its upper or lower end surface comes into contact with the horizontal extension groove line 45. Circular smooth protrusions 844 are provided on both the upper and lower end surfaces, forming a two-way protection mechanism. Whether the upper or lower end surface of the extension power-taking piece 841 comes into contact with the horizontal extension groove line 45 first and causes jamming when extending into the wire slot 46, the protrusions 844 can play the role of reducing friction and assisting in guiding. Through the collaborative work of the protrusions 844 in two directions, the probability of jamming is further reduced, ensuring that the extension power-taking piece 841 can easily break through when encountering obstacles and smoothly connect to the weak-current metal strip 43. Compared with only providing protrusions 844 on one side, the smoothness of the installation process and the overall installation success rate are greatly improved.
[0063] Two second snap rings 87 arranged horizontally at an interval up and down are formed at the bottom of the second rotating seat 81. During the installation process, the second snap rings 87 can quickly and accurately snap into the installation positions in the power supply box, effectively preventing the second rotating seat 81 from shifting or being misaligned in the axial direction and ensuring that the relative position of the second rotating seat 81 and the power supply box remains fixed. A second rotating slot 815 is provided at the bottom of the lowermost second snap ring 87. By inserting a suitable tool (such as a screwdriver, hex wrench, etc.) into the first rotating slot 613, the first rotating seat 61 can be directly driven to rotate to achieve the on / off of weak-current power-taking.
[0064] The circuit assembly 2 includes a circuit board and a communication unit provided on the circuit board. The communication unit is used for remote data communication. In one embodiment, the communication unit can be, for example, a Bluetooth adapter unit, a wifi adapter unit, etc. In actual application, a remote communication connection is established with the terminal device through the communication unit. The terminal device sends an operation instruction to the communication unit, and the communication unit feeds back the operation instruction to the circuit board. The circuit board controls the lamp to perform corresponding operations according to the operation instruction.
[0065] The top of the lamp connector 3 is movably embedded in the connector installation cavity in the power supply box body 1, and a flat contact piece is connected to one side thereof. The circuit board is provided inside the power supply box body 1, and a V-shaped elastic contact piece is connected to the circuit board. The V-shaped elastic contact piece is in movable abutment with the flat contact piece. A dial block is slidably connected to the bottom of the box body, and a first plug is connected above the dial block. A first through hole is provided on one side of the connector installation cavity, and a second through hole is provided above the first through hole. The V-shaped elastic contact piece passes through the second through hole, and the first plug movably passes through the first through hole. A first slot is provided on one side of the lamp connector 3, and the first plug is movably inserted into the first slot.
[0066] By moving the first plug block through the first through hole, the first plug 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. Otherwise, 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.
[0067] 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 flicking, in the present embodiment, preferably, a second spring is provided inside the power supply box body 1, one end of the second spring is connected to a second plug block, a first inclined surface is provided on the upper side of an end of the second plug block away from the second spring, and a second inclined surface is provided on the lower side of an end of the second plug block away from the second spring, a third through hole is provided on the other side of the connector installation cavity, the second plug block 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 block movably plugged into the second slot.
[0068] The purpose is that when the lamp connector 3 is inserted into the joint installation cavity, the lamp connector 3 is guided by the second inclined surface to push the second plug block out of the joint installation cavity. When the lamp connector 3 is fully inserted into the joint installation cavity, the elastic force of the second spring allows the second plug block to pass through the third through hole and then be inserted into the second slot, thereby limiting and locking the lamp connector 3, thereby improving the installation stability of the lamp connector 3, and there is no need to move the second plug block, thereby improving the convenience of use. When the lamp connector 3 is pulled out of the installation cavity 813, the lamp connector 3 is guided by the first inclined surface to push the second plug block out of the installation cavity 813, and there is no need to move the second plug block, thereby improving the convenience of disassembly of the lamp connector 3.
