Description

Track-mounted power supply box, lighting fixtures and mounting mechanism Technical Field

[0001] This invention relates to the field of track lighting technology, and particularly to track-type power supply boxes, lighting fixtures, and mounting mechanisms. Background Technology

[0002] Track lights are lighting fixtures installed on a track. They can slide along the track to change their position, thereby adjusting the illuminated area. Track lights generally consist of a driver power supply box and a lamp body (or lamp panel) located at the bottom of the driver power supply box. The driver power supply box is installed in the track groove via snap-fit ​​components.

[0003] For example, Chinese invention patent CN113251391A discloses a track light driver power supply box and a concealed track light power supply structure. Based on the disclosed technical content and accompanying drawings, it is clear that the driver power supply box is a one-piece structure, not detachable or inconvenient to disassemble. However, during daily use, the power conversion module or connecting parts inside the driver power supply box are easily damaged. When the power conversion module or connecting parts inside the driver power supply box are damaged, or when a power conversion module with different parameters needs to be replaced, because the driver power supply box is a one-piece structure, the power conversion module or connecting parts cannot be replaced individually; the entire driver power supply box must be replaced. However, if the connecting parts or power conversion module are not damaged, replacing the entire driver power supply box would lead to material waste or increased replacement costs. Summary of the Invention

[0004] In order to overcome the shortcomings of the existing technology, the present invention provides a track-mounted power supply box, a lamp and a mounting mechanism.

[0005] The technical solution adopted by this invention to solve its technical problem is: a track-mounted power supply box, comprising:

[0006] The housing contains a power conversion module.

[0007] A mounting base is disposed at at least one end of the housing. The mounting base is provided with a snap-fit ​​component. One of the mounting base and the housing is provided with a plug-in block, and the other is provided with a plug-in groove that mates with the plug-in block. The plug-in block can be inserted into or detached from the plug-in groove, and the plug-in block and the plug-in groove are detachably connected.

[0008] As a further solution, the two side walls of the plug block are provided with first elastic buckles, and the two side walls of the plug groove are provided with first locking holes. The first elastic buckles can be fastened into the first locking holes, thereby realizing a detachable fixed connection between the mounting base and the outer shell.

[0009] As a further embodiment, the housing is provided with the insertion slots at both ends, and the mounting base is provided with the insertion block at one end near the housing.

[0010] As a further embodiment, the rail-mounted power supply box also includes two end caps, which are respectively disposed in the insertion slots at both ends of the housing and are detachably connected to the insertion slots. Each end cap has a positioning slot at one end facing the other. The power conversion module includes a circuit board, with both ends of the circuit board disposed in the positioning slots of the two end caps, so that the circuit board is stably supported inside the housing and electrically connected to the mounting base.

[0011] As a further embodiment, both end caps are provided with clearance holes; both ends of the circuit board are electrically connected to a first conductive sheet, and the first conductive sheet at both ends passes through the clearance holes of the two end caps respectively; a second conductive sheet is provided in the mounting base, the second conductive sheet extends to the plug block, and the second conductive sheet is in electrical contact with the first conductive sheet, which facilitates the disassembly of the mounting base from the housing.

[0012] As a further embodiment, the top of the end cap is provided with a second elastic buckle, and the top wall of the insertion groove is provided with a second locking hole. The second elastic buckle can be fastened into the second locking hole, thereby making the end cap and the outer shell detachably connected.

[0013] As a further embodiment, the bottom of both side walls of the plug-in block is provided with a stop block, and the bottom of both side walls of the end cap is provided with a first clearance opening that mates with the stop block. The end wall of the end cap near the plug-in block is provided with a second clearance opening, and the bottom of the end cap is provided with a third clearance opening. The second clearance opening and the third clearance opening are connected, and the plug-in block can pass through the third clearance opening and the second clearance opening and be placed inside the end cap, further enabling the mounting base and the outer shell to be installed in place.

[0014] As a further embodiment, both sides of the second clearance opening are provided with anti-detachment ridges, which extend in the vertical direction. Both sides of the plug block are provided with anti-detachment grooves that cooperate with the anti-detachment ridges. The anti-detachment grooves are close to the mounting base, and the upper end of the anti-detachment grooves penetrates through the top surface of the plug block. The lower end of the anti-detachment grooves stops at the stop block. The anti-detachment ridges can be inserted into or detached from the anti-detachment grooves in the vertical direction, thereby enhancing the anti-detachment performance of the connection.

[0015] As a further embodiment, a stiffening plate is connected between the two side walls of the end cap, the bottom end of the stiffening plate abuts against the outer shell, and the clearance hole is provided on the stiffening plate. The stiffening plate divides the end cap into a first part that connects to the plug-in block and a second part that plugs into the outer shell, thereby making the connection between the mounting base and the outer shell more secure.

[0016] As a further embodiment, the plug block has an open cavity, the opening extending from the top wall of the plug block to the end wall near the end cap, one end of the second conductive sheet extending into the cavity, and one end of the first conductive sheet passing through the opening and placed in the cavity, ensuring that the first and second conductive sheets can make stable electrical contact inside the plug block.

[0017] As a further embodiment, the locking component includes a rotating component, a locking component, and a driving mechanism. The rotating component is rotatably disposed within the mounting base, and the locking component is disposed on the side wall of the rotating component. Both side walls of the mounting base are provided with fourth clearance openings that mate with the two ends of the locking component. The driving mechanism is connected to the rotating component so that the two ends of the locking component can pass through the fourth clearance openings and extend out of the mounting base or retract into the mounting base, respectively, for locking the entire power supply box within the track groove.

[0018] As a further embodiment, the driving mechanism is a lever, one end of which is connected and fixed to the rotating component, and the other end of which extends out of the mounting base. The mounting base is provided with an movable opening that cooperates with the lever, thereby driving both ends of the snap-fit ​​component to extend or retract from the fourth clearance opening.

[0019] As a further solution, the edge of the movable port is provided with an extension plate horizontally in the direction away from the mounting base, and the edge of the extension plate is provided with an unlocking position and a locking position; the lever is provided with a protrusion, which can be engaged with the unlocking position or the locking position to prevent it from loosening under accidental external force and causing the power box to fall off the track groove, thus causing danger.

[0020] The present invention also provides a lighting fixture, including the above-described track-mounted power supply box, and further including a lamp panel, which is detachably disposed at the bottom of the mounting base or the bottom of the housing.

[0021] The present invention also provides an installation mechanism, including the above-mentioned track-type power box, and a track, the track having an open track groove, and both sides of the track groove having snap-fit ​​positions, the two ends of the snap-fit ​​member being able to snap into the snap-fit ​​positions on both sides of the track groove respectively.

[0022] The beneficial effects of this invention are as follows: Each mounting base and housing has a plug-in block on one side and a plug-in slot on the other side that mates with the plug-in block. The shape of the plug-in block matches the plug-in slot, allowing the plug-in block to be inserted into or detached from the slot. The plug-in block and the slot are detachably connected, allowing them to be fixed or detached. This makes the housing and mounting base independent components. When the power conversion module in the housing is damaged or the snap-fit ​​component on the mounting base is damaged during use, the housing or mounting base can be removed from the power box assembly, replaced with a new housing or mounting base, and reinstalled with the old mounting base or housing. This allows for the reuse of the power conversion module or snap-fit ​​component, avoiding material waste and reducing replacement costs. Attached Figure Description

[0042] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding the present invention, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other. Example

[0043] As shown in Figures 1-3, this embodiment provides a rail-mounted power supply box, including a housing 1 and a mounting base 2.

[0044] As shown in Figure 2, the outer shell 1 is a long strip shell with openings at both ends, forming an internal space. A power conversion module is installed inside the outer shell 1. The power conversion module is used to convert the input electrical energy into stable and compliant output electrical energy to support the stable operation of the lamp body.

[0045] As shown in Figures 1-3, the mounting base 2 is disposed at at least one end of the housing 1. Each mounting base 2 is provided with a snap-fit ​​component 26, which is used to snap the mounting base 2 into the track groove 61, thereby fixing the mounting base 2. It is worth noting that this embodiment has two mounting bases 2, which are respectively disposed at both ends of the housing 1. When only one end of the housing 1 is provided with a mounting base 2, a snap-fit ​​component 26 needs to be provided at the other end of the housing 1 so that the track-mounted power supply box can be stably installed in the track groove 61.

[0046] It is worth noting that, as shown in Figures 2-5, each mounting base 2 and the outer casing 1 are provided with a plug-in block 21 and a plug-in groove 11 that mates with the plug-in block 21. The shape of the plug-in block 21 matches the plug-in groove 11, so that the plug-in block 21 can be inserted into or detached from the plug-in groove 11. The plug-in block 21 and the plug-in groove 11 are detachably connected, specifically by screws or clips, so that the plug-in block 21 and the plug-in groove 11 can be connected and fixed or detached and separated, making the outer casing 1 and the mounting base 2 independent components. When the power conversion module in the outer casing 1 is damaged or the snap-fit ​​component 26 on the mounting base 2 is damaged during use, the outer casing 1 or the mounting base 2 can be removed from the power box as a whole, a new outer casing 1 or mounting base 2 can be replaced, and the old mounting base 2 or outer casing 1 can be reinstalled. This allows for the reuse of the power conversion module or the snap-fit ​​component 26, avoids material waste, and reduces replacement costs.

[0047] In this embodiment, as shown in Figures 3-6, both sides of the plug-in block 21 are provided with first elastic buckles 22 (e.g., elastic plastic blocks integrally formed on the side walls of the plug-in block 21), and both sides of the plug groove 11 are provided with first locking holes 12. The first elastic buckles 22 can be fastened into the first locking holes 12. When the plug-in block 21 is inserted into the plug groove 11, the first elastic buckles 22 on both sides will elastically deform until they are locked into the corresponding first locking holes 12; pressing the first elastic buckles 22 causes them to elastically deform and disengage from the first locking holes 12, thereby realizing a detachable fixed connection between the mounting base 2 and the outer shell 1. The advantage of using the detachable scheme of the first elastic buckles 22 and the first locking holes 12 is that installation and disassembly can be performed without the aid of external tools. In this embodiment, preferably, the two ends of the outer shell 1 are integrally formed with the above-mentioned plug grooves 11, and the end of the mounting base 2 near the outer shell 1 is integrally formed with the above-mentioned plug-in block 21, which can be designed according to actual production requirements.

[0048] It is worth mentioning that, as shown in Figures 2-5, the power conversion module is located inside the housing 1. It mainly includes a long strip-shaped circuit board 4, used to convert external AC power (e.g., from the track 6) into DC power suitable for the operation of the lamp board 5. Therefore, to ensure stable support of the circuit board 4 within the housing 1 and to achieve electrical connection with the mounting base 2, the track-mounted power supply box also includes two end caps 3. The two end caps 3 are respectively located in the insertion slots 11 at both ends of the housing 1, and are detachably connected to the insertion slots 11. Each end cap 3 has a positioning slot 31 at one of its facing ends. The two ends of the circuit board 4 are respectively positioned within the positioning slots 31 of the two end caps 3, thus supporting and positioning the two ends of the circuit board 4. When the two end caps 3 are fixed in the insertion slots 11 at both ends of the housing 1, the circuit board 4 is stably fixed inside the housing 1. Furthermore, since the end caps 3 are detachably connected to the insertion slots 11, specifically through screws or clips, the end caps 3 and the insertion slots 11 can be connected and fixed or detached. When the easily damaged circuit board 4 fails, the end cover 3 can be removed from the insertion slot 11 and a new circuit board 4 can be replaced. The outer casing 1 can be reused, avoiding material waste and reducing replacement costs.

[0049] In this embodiment, as shown in Figures 3, 5, 8, and 9, the top of the end cap 3 is provided with a second elastic buckle 33, and the top wall of the insertion groove 11 is provided with a second locking hole 13. The second elastic buckle 33 can be fastened into the second locking hole 13. When the end cap 3 is pushed into the insertion groove 11, the second elastic buckle 33 will engage with the second locking hole 13 on the top wall of the insertion groove 11, thus achieving fixation; pressing the second elastic buckle 33 causes it to elastically deform and disengage from the second locking hole 13, thereby enabling a detachable fixed connection between the end cap 3 and the outer shell 1. The advantage of using the detachable solution of the second elastic buckle 33 and the second locking hole 13 is that installation and disassembly can be performed without the aid of external tools.

[0050] Furthermore, as shown in Figures 8-9, both end caps 3 are provided with clearance holes 32; both ends of the circuit board 4 are electrically connected to first conductive plates 41, which pass through the clearance holes 32 of the two end caps 3 respectively. When multiple first conductive plates 41 are provided, the clearance holes 32 of the end caps 3 are also provided in a corresponding number, thereby separating and positioning adjacent first conductive plates 41 to avoid short circuits; the mounting base 2 is provided with second conductive plates 23, which extend to the plug-in block 21, and the number of second conductive plates 23 is the same as that of the first conductive plates 41. When the plug-in block 21 is inserted into the plug-in slot 11, the second conductive plates 23 and the first conductive plates 41 make electrical contact, realizing the conduction of current between the mounting base 2 and the outer shell 1. In addition, the electrical contact between the second conductive plates 23 and the first conductive plates 41 also facilitates the disassembly of the mounting base 2 and the outer shell 1.

[0051] It is worth mentioning that the purpose of setting the end cap 3 is to stabilize the circuit board 4 and the first conductive sheet 41, so that the first conductive sheet 41 and the second conductive sheet 23 can make accurate, corresponding and stable electrical contact, and avoid poor contact.

[0052] In this embodiment, further as shown in Figures 6-7, the bottom of both side walls of the insertion block 21 is provided with a stop block 211, and the bottom of both side walls of the end cap 3 is provided with a first clearance opening 34 that mates with the stop block 211. When the insertion block 21 of the mounting base 2 is inserted into the insertion groove 11 from bottom to top, the stop block 211 is locked in the first clearance opening 34, further preventing the mounting base 2 and the outer shell 1 from moving relative to each other in the vertical direction, indicating that both are installed in place. Moreover, preferably, the first elastic buckle 22 is provided on the side wall of the stop block 211, so that the first elastic buckle 22 can be engaged with the first locking hole 12 of the outer shell 1 at the first clearance opening 34.

[0053] As shown in Figures 8-9, the end wall of the end cap 3 near the plug block 21 is provided with a second clearance opening 35, and the bottom of the end cap 3 is provided with a third clearance opening 36. The second clearance opening 35 and the third clearance opening 36 are connected, so that the plug block 21 can pass through the third clearance opening 36 and the second clearance opening 35 from bottom to top and be placed in the end cap 3, thereby inserting into the plug slot 11.

[0054] It is worth mentioning that, to enhance the anti-detachment performance of the connection, as shown in Figures 7-8, anti-detachment ridges 351 are provided on both sides of the second clearance opening 35. The anti-detachment ridges 351 extend vertically, and anti-detachment grooves 212 that mate with the anti-detachment ridges 351 are provided on both sides of the plug-in block 21. The anti-detachment grooves 212 are close to the mounting base 2, with their upper ends penetrating the top surface of the plug-in block 21 and their lower ends stopping at the stop block 211. When the plug-in block 21 of the mounting base 2 is inserted into or disengaged from the plug-in groove 11 from bottom to top, the anti-detachment ridges 351 can be inserted into or disengaged from the anti-detachment grooves 212 vertically. Through the cooperation of the anti-detachment ridges 351 and the anti-detachment grooves 212, the mounting base 2 and the outer casing 1 are connected as a single power supply box. This also prevents the mounting base 2 from detaching laterally under external force, further enhancing the stability of the connection. At the same time, the load-bearing capacity of the power supply box is enhanced in the horizontal direction to prevent it from breaking at the connection between the mounting base 2 and the outer casing 1.

[0055] Based on the above scheme, as shown in Figures 8-9, a stiffening plate 37 is connected between the two side walls of the end cap 3. The stiffening plate 37 is used to strengthen the structural strength and load-bearing capacity of the end cap 3, and the clearance hole 32 is set on the stiffening plate 37. When the anti-detachment rib 351 is inserted into the anti-detachment groove 212, the end of the insertion block 21 abuts against the stiffening plate 37, so that the bottom end of the stiffening plate 37 abuts against the inner bottom surface of the outer shell 1, which plays a role in strengthening and positioning, thereby making the connection between the mounting base 2 and the outer shell 1 more secure. Among them, the stiffening plate 37 divides the end cap 3 into a first part 38 connected to the insertion block 21 and a second part 39 inserted into the outer shell 1.

[0056] In this embodiment, as shown in Figure 7, the plug-in block 21 has a cavity 213 with an opening 214. The opening 214 extends from the top wall of the plug-in block 21 to the end wall near the end cap 3. One end of the second conductive piece 23 extends into the cavity 213, and one end of the first conductive piece 41 passes through the opening 214 and is placed inside the cavity 213. Specifically, when the plug-in block 21 is inserted into the slot from bottom to top, one end of the first conductive piece 41 passes through the opening 214 and is placed inside the cavity 213, ensuring that the first conductive piece 41 and the second conductive piece 23 can make stable electrical contact inside the plug-in block 21.

[0057] Meanwhile, in this embodiment, as shown in Figures 6-7, the snap-fit ​​component 26 is used to lock the entire power supply box within the track groove 61. The snap-fit ​​component 26 includes a rotating component 261, a snap-fit ​​component 262 (usually a hook or a strip), and a drive mechanism. The rotating component 261 is rotatably disposed in the mounting base 2 (such as a rotating shaft). The snap-fit ​​component 262 is disposed on the side wall of the rotating component 261. Both sides of the mounting base 2 are provided with fourth clearance openings that cooperate with the two ends of the snap-fit ​​component 262. The two ends of the snap-fit ​​component 262 correspond to the fourth clearance openings on both sides. The drive mechanism is connected to the rotating component 261 and drives the rotating component 261 to rotate so that the two ends of the snap-fit ​​component 262 can pass through the fourth clearance openings and extend out of the mounting base 2 or retract into the mounting base 2. That is, when the two ends of the snap-fit ​​component 262 pass through the fourth clearance openings and extend out of the mounting base 2, it is snapped into the track groove 61. When the two ends of the snap-fit ​​component 262 retract into the mounting base 2, the power box is removed from the track groove 61.

[0058] As shown in Figures 6-7, the driving mechanism is preferably a lever 263. One end of the lever 263 is connected and fixed to the rotating member 261, and the other end of the lever 263 extends out of the mounting base 2. The mounting base 2 is provided with an movable opening 24 that cooperates with the lever 263. Moving the lever 263 can cause the rotating member 261 to rotate, thereby causing both ends of the locking member 262 to extend or retract from the fourth clearance opening.

[0059] As shown in Figures 6-7, for ease of operation and positioning, an extension plate 25 extending horizontally away from the mounting base 2 is provided along the edge of the movable opening 24. The edge of the extension plate 25 is provided with an unlocking slot 251 and a locking slot 252. A protrusion 2631 is provided on the lever 263. When the latching member 262 retracts, the protrusion 2631 can engage with the unlocking slot 251; when the latching member 262 extends, the protrusion 2631 can engage with the locking slot 252, thereby positioning and fixing the lever 263 and preventing it from loosening under accidental external force, which could cause the power box to detach from the track groove 61 and cause danger. Example

[0060] As shown in Figure 10, this embodiment provides a lighting fixture, including the aforementioned track-mounted power supply box and a lamp panel 5. The lamp panel 5, such as an LED lamp panel 5, is detachably mounted on the bottom of the mounting base 2 or the bottom of the housing 1. For example, a snap-fit ​​can be provided at the bottom of the mounting base 2 or the housing 1, and the lamp panel 5 can be fixed by snap-fit. Alternatively, a flange plate can be provided at the bottom of the mounting base 2 or the housing 1, and a flange plate can also be provided at the top of the lamp panel 5, with the two connected and fixed by screws. Simultaneously, a power port is provided on the mounting base 2, which is electrically connected to the second conductive plate 23. The lamp panel 5 is connected to the power port to obtain power. Example

[0061] As shown in Figures 11-12, this embodiment provides an installation mechanism, including the aforementioned rail-type power box containing the snap-fit ​​component 26, and also including a rail 6. The rail 6 has an open rail groove 61, and both sides of the rail groove 61 have inwardly recessed snap-fit ​​positions 611, such as snap slots or snap holes. During installation, the mounting bases 2 at both ends of the power box are aligned with the open end of the rail groove 61 and inserted. Then, the levers 263 at both ends are moved, causing both ends of the snap-fit ​​component 262 to extend from the fourth clearance opening and snap into the snap-fit ​​positions 611 on both sides of the rail groove 61, thereby securely installing the power box on the rail 6. When disassembly is required, the levers 263 are reversed to retract the snap-fit ​​component 262, allowing the power box to be removed.
