[0032] Power supply device 100. Specific embodiments
[0033] In order to make the objectives, technical solutions, and advantages of the present utility model clearer, the present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.
[0034] Here, it should be noted that in order to avoid obscuring the present utility model due to unnecessary details, only the structures and / or processing steps closely related to the solution of the present utility model are shown in the drawings, while other details less related to the present utility model are omitted.
[0035] In addition, it should also be noted that the term "comprising", "including", or any other variant thereof is intended to cover non-exclusive inclusion, such that a process, method, article, or device comprising a series of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or device.
[0036] Please refer to Figures 1 to 10 As shown, an embodiment of the present utility model provides a track light (not shown), comprising: a track housing (not shown), an electrical part (not shown) disposed in the track housing, and a power supply device 100. The electrical part is actually a metal strip, such as a copper strip, etc., in the track housing. The power supply device 100 is installed in the track housing, the power supply device 100 is electrically connected to the electrical part, and the power supply device 100 supplies power to the track light.
[0037] The power supply device 100 includes: a power supply component 1, a metal housing 2, and two insulating housings 4.
[0038] The power supply component 1 includes a smart control power supply 11 and a driving power supply 12 that are electrically connected. Among them, the driving power supply 12 is used to be electrically connected to the mains power, and the smart control power supply 11 is used to supply power to the track.
[0039] Both the smart control power supply 11 and the driving power supply 12 are installed in the metal housing 2. Since the metal housing 2 has excellent heat dissipation performance, it can timely dissipate the heat generated when the power supply component 1 works, effectively avoiding the risks of performance degradation, shortened lifespan, or even failure of the power supply component 1 caused by high temperature.
[0040] Two insulating cases 4 are respectively arranged at both ends of the metal case 2 along the longitudinal direction to prevent current from flowing from the metal case 2 to the outside or causing an electric shock hazard. One of the two insulating cases 4 is a power input terminal 41, and the other is a power output terminal 42. With such an arrangement, good insulation between the power input terminal 41 and the power output terminal 42 and the external environment is ensured, thereby improving the safety of the entire power supply device 100. Among them, the power input terminal 41 is electrically connected to the driving power supply 12, and the driving power supply 12 and the intelligent control power supply 11 are electrically connected through a cable. The intelligent control power supply 11 is electrically connected to the power output terminal 42 to convert the commercial power into appropriate voltage and current and deliver it to the track light.
[0041] The metal case 2 has a receiving cavity 21 extending along the longitudinal direction, and the power supply unit 1 is arranged in the receiving cavity 21. The longitudinal direction is defined as the length extension direction of the metal case 2, such as Figure 1 the x direction shown. The width direction of the metal case 2 is defined as Figure 1 the y direction shown. The height direction of the metal case 2 is defined as Figure 1 the z direction shown. Among them, the longitudinal direction, the width direction and the height direction are perpendicular to each other in pairs.
[0042] Most of the power supplies for track lights on the market adopt a plastic shell design. The heat generated by high-power electrical components is relatively large, and it is difficult for the plastic case to dissipate the heat, resulting in the electrical components being burned out due to high temperature. Therefore, the power supply with a traditional plastic shell is often limited by its heat dissipation ability, and the power supply cannot reach a high power level. In the power supply device 100 in this embodiment, due to the efficient heat dissipation of the metal case 2, even if the heat generated by high-power electrical components is high, it can be quickly and effectively dissipated to the environment, so that the power supply unit 1 can adapt to high-load operation. Therefore, the power supply unit 1 can reach a high power level.
[0043] Please refer to Figures 1 to 4 As shown, the metal case 2 further includes a partition 22 arranged in the receiving cavity 21, and the partition 22 divides the receiving cavity 21 into two cavities.
[0044] In some embodiments, the partition 22 extends along the longitudinal direction, that is, the partition 22 divides the receiving cavity 21 into a first cavity 211 and a second cavity 212 arranged up and down. Among them, the intelligent control power supply 11 is installed in the first cavity 211, and the driving power supply 12 is installed in the second cavity 212. And, the partition 22 at least partially extends into the insulating case 4, so that the first cavity 211 and the second cavity 212 are communicated with the wire routing cavity 422 of the insulating case 4. The cable between the driving power supply 12 and the intelligent control power supply 11 passes through the wire routing cavity 422 to electrically connect the driving power supply 12 and the intelligent control power supply 11.
[0045] In another embodiment, the partition 22 extends in the height direction, that is, the partition 22 divides the accommodation cavity 21 into a first cavity 211 and a second cavity 212 which are arranged left and right. One of the intelligent control power supply 11 and the drive power supply 12 is arranged in the first cavity 211, and the other is arranged in the second cavity 212. Moreover, the drive power supply 12 is arranged close to the power input end 41, and the intelligent control power supply 11 is arranged close to the power output end 42. A wire avoiding opening 2211 is provided on the partition 22, and the cable between the drive power supply 12 and the intelligent control power supply 11 passes through the wire avoiding opening 2211 to electrically connect the drive power supply 12 and the intelligent control power supply 11.
[0046] In this embodiment, the metal shell 2 and the partition 22 are integrally formed. The integrally formed metal shell 2 naturally forms a continuous electromagnetic shielding layer. This can not only effectively prevent external electromagnetic radiation from interfering with internal electronic components, but also reduce the mutual electromagnetic interference between internal electronic components (such as the intelligent control power supply 11 and the drive power supply 12), ensuring the stable operation of the system and the purity of the signal. Setting the partition 22 between the intelligent control power supply 11 and the drive power supply 12 further enhances the shielding effect and realizes more refined electromagnetic isolation. In other embodiments, the metal shell 2 and the partition 22 can be independently arranged.
[0047] In other embodiments, the partition 22 can be made of other materials with good thermal conductivity and electrical conductivity, such as aluminum, aluminum alloy, iron-nickel alloy, etc., which are not limited herein.
[0048] The metal shell 2 has good electrical conductivity, and the current of the power supply component 1 will conduct to the surface of the metal shell 2, which is likely to cause electric shock accidents. To ensure electrical safety, an insulating member 3 is provided between the power supply component 1 and the accommodation cavity 21, and the insulating member 3 effectively isolates the power supply component 1 and the metal shell 2. Therefore, the risk of electric shock to users or maintenance personnel is avoided, providing an electrical safety protection barrier for the power supply device 100.
[0049] In some embodiments, the insulating member 3 is an insulating film wrapped around the power supply component 1. The insulating film conducts heat to the metal shell 2 for rapid heat dissipation through the metal shell 2.
[0050] In other embodiments, the insulating member 3 is an insulating cylinder 321 with open ends at both ends, and the insulating cylinder 321 is wrapped around the outside of the power supply component 1. Moreover, the wall of the insulating cylinder 321 is very thin, which is conducive to quickly conducting heat to the metal shell 2 for rapid heat dissipation through the metal shell 2.
[0051] Please refer to Figure 4 As shown, the insulating member 3 includes a first insulating member 31 and a second insulating member 32. The first insulating member 31 is arranged between the intelligent control power supply 11 and the first cavity 211, and the second insulating member 32 is arranged between the drive power supply 12 and the second cavity 212.
[0052] Please refer to Figure 4 As shown, the second insulating member 32 includes an insulating cylinder 321, and the insulating cylinder 321 is wrapped around the outside of the driving power supply 12. The ends of the electrical components in the driving power supply 12 have sharp parts that may pierce the insulating cylinder 321, causing the electrical components to directly contact the metal housing 2 and resulting in electric leakage.
[0053] To reduce the risk of electric leakage, in this embodiment, the second insulating member 32 further includes an insulating gasket 322. A groove (not shown) is provided on the bottom wall of the second cavity 212, and the insulating gasket 322 is disposed in the groove and abuts against the insulating cylinder 321. The insulating gasket 322 serves as an additional protective layer. After the sharp part of the electrical component in the driving power supply 12 pierces the insulating cylinder 321, it contacts the insulating gasket 322 instead of the metal housing 2. Thus, the risk of electric leakage is significantly reduced, and the electrical safety performance of the power supply device 100 is improved.
[0054] In some other embodiments, the insulating cylinder 321 can also adopt a bottom-thickened structure, effectively preventing the sharp parts of the electrical components in the driving power supply 12 from piercing the insulating cylinder 321, thereby significantly reducing the risk of electric leakage and improving the electrical safety performance of the entire device.
[0055] In some other embodiments, an insulating sleeve (not shown) that matches the insulating cylinder 321 can also be selected, and the sharp parts of the electrical components are provided with the insulating sleeve. The insulating sleeve should have good flexibility and insulating performance to ensure that it will not fall off or be damaged when the electrical components move or vibrate.
[0056] Please refer to Figures 4 to 10 As shown, the insulating housing 4 includes a top surface 44 facing the track light and a bottom surface 45 disposed opposite to the top surface 44. The top surface 44 is provided with a mounting portion 441, and the power supply device 100 is mounted on the track housing through the mounting portion 441. In this embodiment, the mounting portion 441 is a clamping claw. In other embodiments, the mounting portion 441 can also be an elastic buckle, which is not limited herein.
[0057] One end of the insulating housing 4 is provided with a first surface 4511 and a second surface 4512 having a height difference, and a connecting surface 4513 connecting the first surface 4511 and the second surface 4512. The first surface 4511 and the connecting surface 4513 are recessed inward relative to the second surface 4512 to form an abutting groove 451, and the second surface 4512 is flush with the bottom surface of the metal housing 2. The abutting groove 451 abuts against the bottom wall 2121 of the metal housing 2, and the first surface 4511 is located above the bottom wall 2121, achieving the effect that part of the insulating housing 4 is embedded in the metal housing 2. Thus, the visual thickness of the overall product is reduced, and the exposed area of the metal material is relatively increased, making the metal texture more prominent and improving the overall aesthetics of the product.
[0058] The insulating housing 4 has a first part 47 and a second part 48 arranged vertically. A wire routing cavity 422 is provided in the second part 48. At least one mounting hole 2212 is provided at each of the two end portions 221 of the partition 22. At least two fixing portions 423 are provided in each of the two wire routing cavities 422. The fastener 43 passes through the mounting hole 2212 and is fixedly connected to at least one of the fixing portions 423, thereby fixing the partition 22 in the second part 48. A fixing hole corresponding to at least one of the other fixing portions 423 is provided in the first part 47. The fastener 43 passes through the fixing hole to fix the first part 47 to the second part 48. The first part 47 can cover the second part 48 to close the two open ends of the metal housing 2.
[0059] A stepped portion 412 protruding away from the top surface 44 is further provided on the bottom surface of the power input terminal 41. The stepped portion 412 is at least partially exposed outside the track light. A radio component is installed in the stepped portion 412. The radio component is mainly composed of an antenna for transmitting signals. The antenna located in the stepped portion 412 is exposed outside the mounting track, increasing the signal transmission distance and facilitating maintaining signal stability.
[0060] Please refer to Figure 2 、 Figure 3 、 Figure 5 and Figure 10 As shown in
[0061] In some embodiments, the wire avoiding opening 2211 is chamfered so that the edge is smooth without sharp corners, reducing the risk of the wire being scratched or damaged during installation and maintenance.
[0062] The power input terminal 41 is provided with an input wire 411. A round hole is provided on the side surface of the insulating housing 4 for the input wire 411 to pass through. The input wire 411 passes through the round hole and enters the insulating housing 4 and is electrically connected to the power supply component 1. The input wire 411 is electrically connected to the power supply component 1, and the power supply component 1 can convert the commercial power into low-voltage direct current or alternating current suitable for the track light. The power output terminal 42 is provided with a power supply part 421, and the power supply part 421 electrically connects the power supply component 1 and the track light. The power supply component 1 outputs low-voltage electricity through the power supply part 421 to supply power to the track light.
[0063] Please refer to Figure 7As shown, a pull prevention plate 414 is further provided in the wiring cavity 422 of the power input terminal 41. A limit hole 4141 is provided on the pull prevention plate 414. The input wire 411 passes through the limit hole 4141 and is limited and fixed by the limit hole 4141, preventing the input wire 411 from being accidentally pulled under external factors. Thus, it effectively prevents the input wire 411 from loosening or falling off under the action of external force, and further ensures the stable electrical connection between the power input terminal 41 and the mains electricity.
[0064] Please refer to Figures 4 to 8 As shown, the input wire 411 includes a ground wire 4111 and a power wire 4112. The ground wire 4111 is connected to the partition plate 22 and configured to be grounded to ensure electrical safety. At the power input terminal 41, the power wire 4112 is electrically connected to the drive power supply 12 to transmit the mains electricity to the drive power supply 12. The power supply unit 1 can convert the mains electricity into low-voltage direct current or alternating current suitable for use in the track light. At the power output terminal 42, the power supply unit 1 is electrically connected to the intelligent control power supply 11 through a wire. The power supply unit 1 transmits the low-voltage direct current or alternating current to the intelligent control power supply 11 through the wire. The intelligent control power supply 11 is electrically connected to the power supply part 421, and transmits the current through the power supply part 421. The power supply part 421 is electrically connected to the electrical part, and the power supply device 100 transmits the converted current to the electrical part through the power supply part 421, thereby supplying power to the track light.
[0065] A reset switch 46 is provided at the bottom of the insulating housing 4. A reset hole corresponding to the reset switch 46 is provided on the bottom surface 45 of the insulating housing 4, and the reset hole provides an interface for user operation. When the power supply device 100 encounters an abnormal situation (such as the trigger of overload protection), the user only needs to press the reset switch 46 through the reset hole to perform a reset operation and attempt to restore the normal working state of the power supply device 100.
[0066] In summary, compared with the prior art, in the power supply device 100 of the present utility model, by installing the power supply unit 1 into the metal housing 2, the metal housing 2 can quickly and effectively dissipate the heat generated by the power supply unit 1 during operation into the surrounding environment, effectively avoiding the risk of performance degradation, shortened lifespan or even failure of the power supply unit 1 due to high temperature, and ensuring the long-term stable operation of the power supply device 100. The power supply unit 1 and the metal housing 2 are effectively isolated by the insulating member 3, avoiding the risk of electric shock to users or maintenance personnel, and providing an electrical safety protection barrier for the power supply device 100. In addition, insulating housings 4 are respectively provided at both ends of the metal housing 2 along the longitudinal direction to prevent current from flowing from the metal housing 2 to the outside or causing an electric shock hazard, providing an electrical safety protection barrier for the power supply device 100 and achieving double insurance.
[0067] The above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention.
