[0001] This invention relates to a power connection module and a lighting fixture, belonging to the field of lighting fixtures. Background Technology

[0002] The power connection modules in existing track lights are usually straight and long. The release buttons of the power connection module are located on both sides of the power connection module, and after the power connection module is installed, the release buttons are located inside the track. If the track is small, fingers cannot be inserted, which makes it inconvenient to replace and adjust the lights.

[0003] In view of this, it is indeed necessary to propose a power connection module and a lighting fixture to solve the above problems. Summary of the Invention

[0004] The purpose of this invention is to provide a power connection module and a lamp that are easy to install and disassemble.

[0005] To achieve the above objectives, the present invention provides a power connection module, including a housing and a pair of extensions extending outward from both ends of the housing along its length.

[0008] As a further improvement of the present invention, the pressing part is integrally formed with the first buckle, and the other end of the pressing part is provided with a first elastic member for resetting the pressing part. The first elastic member abuts against the inner side of the housing. The third buckle is connected to the first buckle and the second buckle through a guide member. The housing is provided with a first sliding groove for the guide member to slide. The pressing part generates displacement so that the guide member slides along the first sliding groove to drive the second buckle and the third buckle to generate displacement respectively.

[0009] As a further improvement of the present invention, the base is provided with a first guide groove and a second guide groove, the bottom of the first buckle is provided with a first guide portion that slides along the first guide groove, the bottom of the second buckle is provided with a second guide portion that slides along the second guide groove, the guide member is provided with a third guide groove and a fourth guide groove, the top of the first buckle is provided with a third guide portion that slides along the third guide groove, and the top of the second buckle is provided with a fourth guide portion that slides along the fourth guide groove.

[0011] As a further improvement of the present invention, the third buckle is provided with a receiving cavity and a second elastic member abutting against the inner side of the housing. The second elastic member is used to reset the third buckle. The guide member has a fifth guide portion protruding towards the receiving cavity. The inner wall of the receiving cavity is formed with a guide surface for the fifth guide portion to abut against. The extension direction of the guide surface on the horizontal plane is not parallel to the deformation direction of the second elastic member.

[0012] As a further improvement of the present invention, the inner wall of the receiving cavity is further provided with a protruding first limiting part, and the fifth guiding part is located in front of the first limiting part along the deformation direction of the second elastic member, so as to prevent the third buckle from continuing to move.

[0013] As a further improvement of the present invention, the height of the extension in the vertical direction is less than the height of the housing in the vertical direction, and the orthographic projection of the pressing part in the vertical direction overlaps with the orthographic projection of the extension in the vertical direction.

[0014] As a further improvement of the present invention, the power connection assembly includes a pair of power connection springs and an electric wire connected to the power connection springs and extending to the outside of the housing. The pair of power connection springs have fixed ends and free ends arranged opposite to each other. The power connection springs are disposed in the housing and fixed to the base by the fixed ends.

[0025] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0026] It should be noted that, in order to avoid obscuring the present invention with unnecessary details, only the structures and / or processing steps closely related to the present invention are shown in the accompanying drawings, while other details that are not closely related to the present invention are omitted.

[0027] Additionally, it should be noted that the terms “comprising,” “including,” or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0028] like Figures 1 to 7 As shown, this invention discloses a lighting fixture, which is a rail lamp, including a rail, a power connection module 100, and a lamp body. The rail is mounted on a mounting base. The power connection module 100 is electrically connected to both the rail and the lamp body to supply power to the lamp body, and the power connection module 100 can slide freely along the rail. For clarity, the following description will use the power connection module 100 as an example for detailed explanation.

[0029] The power connection module 100 includes a housing 10, which is flat and has its top partially embedded in the guide rail. The length direction of the housing 10 is the extension direction of the guide rail, and the thickness direction of the housing 10 is perpendicular to the extension direction of the guide rail. The bottom of the housing 10 protrudes from the guide rail and is used to connect to the lamp body. Preferably, the housing 10 can be arc-shaped, that is, the cross-section of the housing 10 on the horizontal plane is arc-shaped, so that the power connection module 100 can adapt to the arc-shaped guide rail.

[0030] like Figure 1 As shown, the housing 10 is provided with a pair of extensions 11 at both ends along its length. The extensions 11 are integrally formed with the housing 10, and their vertical height is less than that of the housing 10, thus increasing the length of the housing 10 within the guide rail. Furthermore, a magnet 111 is provided at the upper end of each extension 11, and the upper end of the magnet 111 is flush with the surface of the upper end of the housing 10, allowing the housing 10 to be magnetically fixed to the guide rail. It should be noted that since the housing 10 can be arc-shaped, the extensions 11 can also be arc-shaped along the same direction as the housing 10 to accommodate an arc-shaped guide rail.

[0031] like Figure 2As shown, in addition to the magnet 111, the housing 10 is also provided with a buckle assembly 20 for fixing the power connection module 100 and a power connection assembly 30 for connecting to the mains power. The buckle assembly 20 and the power connection assembly 30 are both located on two sides in the thickness direction of the housing 10.

[0032] Specifically, the latching assembly 20 includes a base 21, a pressing part 22, a first latch 23, a second latch 24, a third latch 25, and a guide member 26. The base 21 is disposed at the bottom of the housing 10 and is used to support the latching assembly 20 and the power connection assembly 30. The first latch 23 and the second latch 24 are disposed opposite to each other on the base 21, the guide member 26 is disposed on the first latch 23 and the second latch 24, and the third latch 25 is disposed on the guide member 26.

[0033] The base 21 is provided with a first guide groove 211 and a second guide groove 212. There are two of each of the first guide groove 211 and the second guide groove 212. The first guide groove 211 is parallel to each other, the second guide groove 212 is parallel to each other, and the first guide groove 211 and the second guide groove 212 are staggered.

[0034] The bottom of the first buckle 23 is provided with a first guide portion 231 that slides along the first guide groove 211, and the bottom of the second buckle 24 is provided with a second guide portion 241 that slides along the second guide groove 212. There are two of each of the first guide portion 231 and the second guide portion 241. This arrangement allows the first buckle 23 to slide relative to the base 21 along the first guide groove 211, and the second buckle 24 to slide relative to the base 21 along the second guide groove 212.

[0035] Specifically, the extension direction of the first guide groove 211 is parallel to the extension direction of the second guide groove 212, so that the first latch 23 and the second latch 24 can move relative to each other or in opposite directions.

[0036] Preferably, the pressing part 22 is integrally formed with the first buckle 23, and the pressing part 22 is located below the buckle assembly 20. By pressing the pressing part 22, the first buckle 23 can move along the first guide groove 211. The other end of the pressing part 22 is provided with a first elastic member 221 for resetting the pressing part 22. The first elastic member 221 extends toward the second buckle 24 and passes through the second buckle 24 to abut against the inner side of the housing 10. It should be noted that the first elastic member 221 and the second buckle 24 do not interfere with each other. When the pressing part 22 is pressed, the first buckle 23 moves accordingly and drives the first elastic member 221 to compress, so that the first buckle 23 moves toward the second buckle 24. When the pressing part 22 is released, the first elastic member 221 drives the pressing part 22 and the first buckle 23 to reset.

[0037] Since the guide member 26 is located at the upper end of the first buckle 23 and the second buckle 24, the guide member 26 has a third guide groove 261 and a fourth guide groove 262. The top of the first buckle 23 has a third guide portion 232 that slides along the third guide groove 261, and the top of the second buckle 24 has a fourth guide portion 242 that slides along the fourth guide groove 262. That is, the first buckle 23 can slide along the first guide groove 211 and the third guide groove 261, and the second buckle 24 can slide along the second guide groove 212 and the fourth guide groove 262.

[0038] In a preferred embodiment of the present invention, on a horizontal plane, the extending direction of the first guide groove 211 is not parallel to the extending direction of the third guide groove 261, the extending direction of the first guide groove 211 is not parallel to the extending direction of the fourth guide groove 262, and the extending direction of the third guide groove 261 is not parallel to the extending direction of the fourth guide groove 262. This arrangement causes the third guide groove 261 to be obliquely positioned relative to the first guide groove 211, and the fourth guide groove 262 to be obliquely positioned relative to the second guide groove 212. That is, when the first buckle 23... When the guide part 231 slides along the first guide groove 211, the third guide part 232 slides along the third guide groove 261 and abuts against the inclined third guide groove 261, so that the force along the movement direction of the first buckle 23 is decomposed in the vertical direction, driving the guide member 26 to move in a direction perpendicular to the movement direction of the first buckle 23. The specific movement direction of the guide member 26 can be determined according to the inclination direction of the third guide groove 261, and the included angle between the third guide groove 261 and the fourth guide groove 262 is toward the movement direction of the guide member 26.

[0039] Combination Figure 5As shown, the housing 10 further includes a first sliding groove 12 for the guide member 26 to slide. The extension direction of the first sliding groove 12 is approximately perpendicular to the movement direction of the first buckle 23. When the guide member 26 slides, the fourth guide groove 262, which is also inclined, abuts against the fourth guide portion 242 as it moves with the guide member 26. This decomposes the force exerted on the fourth guide portion 242 along the movement direction of the guide member 26 into the opposite direction along the movement direction of the first buckle 23. This allows the fourth guide portion 242 to drive the second buckle 24 to slide along the second guide groove 212 and the fourth guide groove 262. In other words, when the first buckle 23 triggers the pressing portion 22 and moves under the action of an external force, the second buckle 24 can move synchronously with the first buckle 23 under the transmission of the guide member 26.

[0040] Furthermore, since the extension direction of the third guide groove 261 is not parallel to the extension direction of the fourth guide groove 262, the initial position of the third guide part 232 in the third guide groove 261 can be controlled to move away from the fourth guide groove 262, and the initial position of the fourth guide part 242 in the fourth guide groove 262 can be controlled to move away from the third guide groove 261, so that the first latch 23 and the second latch 24 can move in opposite directions. That is, when the first latch 23 moves toward the second latch 24, the second latch 24 can also move toward the first latch 23 synchronously. When the first latch 23 moves away from the second latch 24, the second latch 24 can also move away from the first latch 23 synchronously.

[0041] The third buckle 25 is located above the guide member 26. The housing 10 is provided with a dividing rib 13. The extending direction of the dividing rib 13 is the same as the moving direction of the first buckle 23, and divides part of the first slide groove 12 into a second slide groove 14 for the third buckle 25 to slide. The extending direction of the second slide groove 14 is different from the extending direction of the first slide groove 12, and the extending direction of the second slide groove 14 is the same as the moving direction of the first buckle 23.

[0042] The third latch 25 has a receiving cavity and a second elastic member 251 that abuts against the inner side of the housing 10. The second elastic member 251 is used to reset the third latch 25. The guide member 26 has a fifth guide portion 263 protruding towards the receiving cavity. The inner wall of the receiving cavity has a guide surface 252 for the fifth guide portion 263 to abut against. The extension direction of the guide surface 252 on the horizontal plane is not parallel to the deformation direction of the second elastic member 251. When the first latch 23 drives the guide member 26 to move, the guide member 26 causes the fifth guide portion 263 to abut against the guide surface 252. Through force decomposition, the third latch 25 moves in a direction perpendicular to the movement direction of the guide member 26. That is, the movement direction of the third latch 25 is consistent with the movement direction of the first latch 23 or the second latch 24, and can move synchronously with the first latch 23.

[0043] The inner wall of the receiving cavity is further provided with a protruding first limiting part 253. The fifth guide part 263 is located in front of the first limiting part 253 along the deformation direction of the second elastic member 251, so as to prevent the third buckle 25 from continuing to move. That is, in the natural state, when the third buckle 25 moves directly under the action of external force, rather than under the transmission of the first buckle 23, the first limiting part 253 can restrict the movement of the third buckle 25 to play a safety role.

[0044] When the third latch 25 is displaced under the action of the first latch 23, the fifth guide portion 263 moves along the movement direction of the guide member 26, that is, along the extension direction of the first limiting portion 253, so that the fifth guide portion 263 is no longer located in front of the first limiting portion 253, but is offset, thus enabling the third latch 25 to correctly displace. Furthermore, when the pressing portion 22 is released, the first latch 23 resets, the guide member 26 resets accordingly, and the fifth guide portion 263 no longer abuts against the guide surface 252. The third latch 25 then resets under the action of the second elastic member 251. The first elastic member 221 and the second elastic member 251 are preferably springs.

[0045] Combination Figure 3 , Figure 4 and Figure 6 As shown, the guide member 26 also has a second limiting portion 264 extending upward. The second limiting portion 264 may be a reinforcing rib to strengthen the structure of the guide member 26. The second limiting portion 264 and the third buckle 25 are located at the same level and are respectively located on both sides of the partition rib 13. The second limiting portion 264 restricts the movement of the guide member 26 by abutting against the partition rib 13.

[0046] Combination Figure 6 As shown, it should be noted that the housing 10 has two windows on each of its two sides in the thickness direction, for a total of four windows. The first buckle 23, the second buckle 24, and the third buckle 25 are all disposed inside the housing 10. The first buckle 23 has a first abutting portion 233 extending outside the housing 10 and a pressing portion 22. The second buckle 24 has a second abutting portion 243 extending outside the housing 10. The third buckle 25 has a third abutting portion 254 extending outside the housing 10. The first abutting portion 233, the pressing portion 22, the second abutting portion 243, and the third abutting portion 254 each extend outside the housing 10 through a window. The first abutting portion 233 and the pressing portion 22 are located on the same side, and the second abutting portion 243 and the third abutting portion 254 can be located on the same side. That is, the first abutting portion 233 and the second abutting portion 243 are respectively disposed on two sides in the thickness direction of the housing 10.

[0047] Combination Figure 7 As shown, it can be understood that the size of the pressing part 22 can be relatively large to facilitate pressing with fingers. The first abutment part 233, the second abutment part 243, and the third abutment part 254 are all similar to a locking tongue structure. When the pressing part 22 is pressed, the pressing part 22 together with the first abutment part 233 retracts into the housing 10. The first latch 23 is linked with the second latch 24 and the third latch 25, and drives the second abutment part 243 and the third abutment part 254 to retract into the retracted housing 10 so as to be inserted into the guide rail. After being inserted into the guide rail, after the pressing part 22 is released, the first abutment part 233, the second abutment part 243, and the third abutment part 254 all protrude from the housing 10 to be inserted into the track of the guide rail, and at the same time limit the power receiving module 100 to prevent the power receiving module 100 from separating from the guide rail.

[0048] Specifically, the pressing part 22 is disposed at the lower end of the housing 10, and after the power connection module 100 is installed in conjunction with the guide rail, the pressing part 22 is located below the guide rail to facilitate operation, that is, the vertical projection of the pressing part 22 overlaps with the vertical projection of the extension 11.

[0049] Combination Figure 2As shown, the power connection assembly 30 includes a pair of power connection springs 31 and a wire 32 connected to the power connection springs 31 and extending to the outside of the housing 10. The wire 32 passes through both ends of the housing 10 located at the lower end of the extension 11 and extends downward to connect to the lamp body. The pair of power connection springs 31 have fixed ends and free ends arranged opposite to each other. The power connection springs 31 are disposed in the housing 10 and fixed to the base 21 by the fixed ends. The base 21 is provided with a fixing groove 27 for fixing the power connection springs 31. The fixed ends of the power connection springs 31 are fixed in the fixing groove 27. The free ends are provided with a fourth abutment part 311. The two sides of the housing 10 in the thickness direction are also provided with two windows to allow the fourth abutment parts 311 of the pair of power connection springs 31 to pass through the housing 10. When the latching assembly 20 retracts into the housing 10, the fourth abutting part 311 retracts inward under the abutment of the inner wall of the guide rail, causing the electrical contact spring 31 to undergo elastic deformation, and pops out after being installed in place to electrically connect with the neutral wire and the live wire in the guide rail respectively.

[0050] In summary, by placing the button of the snap-fit ​​assembly 20 below the power connection module 100, the present invention facilitates the installation and removal of the power connection module 100.

[0051] The above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention.
