Description

Technical Field

[0001] This application relates to the field of magnetic track lights, and more particularly to a ball-head plunger type magnetic track light. Background Technology

[0002] In this rapidly developing era of smart technology, magnetic track lights have gained popularity in the smart home market and become an important element in interior lighting design. Magnetic track lights include downlights, floodlights, grille lights, folding grille lights, pendant lights, and more, covering various lighting needs such as point, line, and surface lighting.

[0003] Magnetic track lights and track power supplies are installed together on the track, which acts like a large "power strip." The track power supply conducts electricity to the magnetic track lights through the track. The advantages of magnetic track lights are: they can be flexibly adjusted on the track, installation and removal from the track are very convenient, and multiple magnetic track lights can share a single track, and multiple tracks can share a single track power supply. This makes the installation and arrangement of magnetic track lights flexible and versatile, meeting diverse lighting needs.

[0004] Existing magnetic track lights are generally installed on the track using a combination of magnetic attraction and clips. These clips include elastic arm clips and telescopic clips. Elastic arm clips are integrally molded into the housing, resulting in weak locking force and a risk of falling off. Telescopic clips require pressing a button at the end of the connecting part to detach the magnetic track light, but the connecting part is deeply hidden inside the track, making disassembly inconvenient.

The disassembly process is convenient and quick.

[0006] Another objective of this invention is to provide a ball-head plunger type magnetic track light, wherein the elastic force of the second ball-head plunger is less than that of the first ball-head plunger, thereby improving the compressibility of the second ball-head plunger.

[0051] Please see Figures 1-16 This utility model provides a ball-head plunger type magnetic track light 100 (hereinafter referred to as track light 100), which is specifically described. The track light 100 includes a light body 2 for emitting light and illumination; and a connecting part 1 connected to the light body 2. The connection method between the connecting part 1 and the light body 2 includes fixed connection, movable connection, flexible connection, etc. Figures 1-4As shown, the connecting part 1 is used to connect to the magnetic track 3. First ball-head plungers 111 are provided on both sides of the connecting part 1, and the connecting part 1 is engaged with the magnetic track 3 via the first ball-head plungers 111. Second ball-head plungers 112 are also provided on both sides of the connecting part 1, and the second ball-head plungers 112 are used to abut against and conduct through the magnetic track 3. The second ball-head plungers 112 are electrically connected to the lamp body 2, so that the lamp body 2 is connected to the magnetic track 3. The magnetic track 3 is provided with a magnetic connecting groove 31 that mates with the connecting part 1 for installing the connecting part 1. The width of the magnetic connecting groove 31 is slightly wider than that of the connecting part 1. Engaging grooves 32 are provided on both sides of the magnetic connecting groove 31 at positions corresponding to the first ball-head plungers 111, facing the track extension direction. When the connecting part 1 is installed on the magnetic track 3, the first ball-head plungers 111 engage with the engaging grooves 32 to prevent the track light 100 from falling off. The first ball-head plunger 111 can slide along the locking groove 32, thereby allowing the track light 100 to adjust its position along the magnetic track 3. Conductive strips 33 are provided on both sides of the magnetic connection groove 31 at positions corresponding to the second ball-head plunger 112, facing the track extension direction. The conductive strips 33 are embedded in the sidewalls of the magnetic connection groove 31, and are insulated from the track base 35 of the magnetic track 3. When the connecting part 1 is installed on the magnetic track 3, the second ball-head plunger 112 abuts against the conductive strip 33 to achieve electrical conductivity between them. The magnetic track 3 is equipped with a track power supply (not shown in the figure), which is connected to the conductive strips 33. The conductive strips 33 on both sides of the magnetic connection groove 31 respectively carry positive and negative DC current. The electrical energy provided by the track power supply is transmitted through the conductive strips 33 to the second ball-head plunger 112, and then through the second ball-head plunger 112 to the lamp body 2, causing the lamp body 2 to emit light. The track light 100 provided by this utility model can be a downlight, floodlight, grid light, folding grid light, pendant light, etc. The structure of the light body 2 will also be different depending on the type of track light 100.

[0052] When installing the track light 100 provided by this utility model, the user only needs to push the connecting part 1 upward into the magnetic connection groove 31 until the first ball plunger 111 is engaged in the snap-fit ​​groove 32 to complete the installation. The installation process is convenient and quick. When disassembling the track light 100, the user only needs to pry the light body 2 downward, and the light body 2 will drive the connecting part 1 downward to disengage from the magnetic connection groove 31 to remove the track light 100. The disassembly process is convenient and quick.

[0053] During the design process, researchers discovered that the contact state between the second ball-head plunger 112 and the magnetic track 3 is significantly affected by the dimensional accuracy of the magnetic connection groove 31. When the width of the magnetic connection groove 31 exceeds the preset range, the second ball-head plunger 112 will experience poor contact, resulting in poor conductivity between the second ball-head plunger 112 and the conductive strip 33. Therefore, in some embodiments, such as... Figure 3 and Figure 4 As shown, when the connecting part 1 is installed in the magnetic connection groove 31, the second ball plunger 112 is compressed by the conductive strip 33. The elastic force of the second ball plunger 112 is less than that of the first ball plunger 111, which improves the compressibility of the second ball plunger 112. Therefore, in the design, the gap between the side of the connecting part 1 and the magnetic connection groove 31 can be made smaller, resulting in a greater compression of the second ball plunger 112. Consequently, even when the width error of the magnetic connection groove 31 is large, it can still ensure good contact between the second ball plunger 112 and the magnetic connection groove 31, thus ensuring conductivity between the connecting part 1 and the magnetic track 3. Furthermore, because the sidewall of the magnetic connection groove 31 is uneven, reducing the elastic force of the second ball plunger 112 can reduce the resistance during the installation and removal of the track light 100, facilitating its installation and removal. Furthermore, because the first ball plunger 111 has a large elastic force, it is not easy for the first ball plunger 111 to disengage from the locking groove 32, which improves the connection stability between the track light 100 and the magnetic track 3.

[0054] Furthermore, the ball head 113 of the first ball head plunger 111 is made of stainless steel, which has extremely high hardness and strength and is not easily deformed, thereby increasing the elasticity of the first ball head plunger 111 and thus improving the connection stability between the track light 100 and the magnetic track 3; moreover, the ball head 113 is made of stainless steel, which is not easily worn and has a longer service life.

[0055] In one embodiment, such as Figure 3 and Figure 2As shown, the magnetic track 3 includes a track base 35 extending in the direction of the magnetic track 3. The track base 35 includes a top wall and side walls connected to both sides of the top wall. The top wall and the two side walls of the track base 35 enclose the magnetic connection groove 31, which has an opening facing downwards and extends through both ends of the magnetic track 3. Insulating strips 34 are embedded in the side walls of the track base 35, and conductive strips 33 are embedded in the insulating strips 34 and exposed on the sides of the insulating strips 34, allowing the second ball-head plunger 112 to abut against the conductive strips 33. The insulating strips 34 fix the conductive strips 33 to the track base 35 and insulate the conductive strips 33 from the track base 35. The conductive strips 33 have a vertical cross-section to increase their longitudinal width, ensuring that the second ball-head plunger 112 can accurately abut against the conductive strips 33. A magnetic iron piece 36 is provided on the top of the magnetic connection groove 31 of the track base 35, and the magnetic iron piece 36 is used to magnetically connect to the track light 100.

[0056] In one embodiment, such as Figure 3 As shown, there are four conductive strips 33 in total. Two conductive strips 33 are respectively provided on both sides of the magnetic connection groove 31. The conductive strips 33 on the same side are in the same vertical position. The track light 100 provided in this embodiment only abuts against the upper conductive strip 33, while the lower conductive strip 33 is used to adapt to other models of track lights.

[0057] In some embodiments, both the second ball plunger 112 and the first ball plunger 111 are good electrical conductors, and the resistivity of the second ball plunger 112 is lower than that of the first ball plunger 111, thereby improving the conductivity of the second ball plunger 112. In a specific embodiment, such as Figure 10 As shown, the first ball-head plunger 111 and the second ball-head plunger 112 have the same structure, both including a plunger cylinder 114, a plunger spring 115, and a ball head 113. The tail end of the plunger cylinder 114 is closed, and the ball head 113 is disposed at the opening of the plunger cylinder 114. The ball head 113 can slide along the plunger cylinder 114 and is restricted from sliding out of the plunger cylinder 114. The plunger spring 115 is disposed inside the plunger cylinder 114 and abuts against the ball head 113, providing the ball head 113 with an outward elastic force. In one embodiment, the ball head 113 of the second ball-head plunger 112 is made of copper, and the ball head 113 of the first ball-head plunger 111 is made of stainless steel, so that the resistivity of the second ball-head plunger 112 is lower than that of the first ball-head plunger 111. In addition, since the conductive strip 33 of the magnetic track 3 is made of copper, the ball head 113 of the second ball head plunger 112 is also made of copper to prevent wear of the conductive strip 33.

[0058] In some embodiments, such as Figures 7-9 As shown, the two sides of the connecting portion 1 include a first side and a second side arranged opposite to each other. A second ball-head plunger 112 is respectively provided on the first side and the second side. The second ball-head plunger 112 is constructed as a rotating body. The rotation center line of the second ball-head plunger 112 on the first side is staggered from the rotation center line of the second ball-head plunger 112 on the second side, thereby reserving space for wiring of the second ball-head plunger 112 and reducing the distance between the two second ball-head plungers 112 in the width direction of the connecting portion 1, thus reducing the width of the connecting portion 1. Furthermore, the two second ball-head plungers 112 are at the same horizontal height, and the distance between the rotation center lines of the two second ball-head plungers 112 is 8mm.

[0059] In some embodiments, such as Figures 9-11 As shown, the connecting part 1 has a second insertion hole 12 at a corresponding position of each of the second ball plungers 112. The second ball plungers 112 are inserted into the second insertion holes 12, and the tail end of the second ball plunger 112 is connected to a first wire 13. The first wire 13 is directly or indirectly electrically connected to the lamp body 2. Here, "electrical connection" can be understood as a conductive connection. Further, as... Figure 10 As shown, the plunger cylinder 114 of the second ball plunger 112 has a second shoulder 1121 radially protruding at one end near the ball head 113. The second insertion hole 12 has a second limiting step 121 at its opening. The second shoulder 1121 abuts against the second limiting step 121 to restrict the movement of the second ball plunger 112 toward the inside of the second insertion hole 12, thereby axially positioning the second ball plunger 112. Further, the second insertion hole 12 is constructed as a cylindrical through hole. The second insertion hole 12 and the second ball plunger 112 are press-fitted. When assembling the second ball plunger 112, it is only necessary to press the second ball plunger 112 into the second insertion hole 12 until the second shoulder 1121 abuts against the second limiting step 121 to complete the assembly. Then, the first wire 13 is welded to the tail end of the second ball plunger 112.

[0060] Furthermore, such as Figure 5 and Figure 14 As shown, the connecting part 1 includes a housing 14, a magnetic absorbing assembly 15, and a circuit board 16. The magnetic absorbing assembly 15 is used to magnetically connect to the magnetic track 3 to improve connection stability. The housing 14 is constructed as a box structure with an open top. The magnetic absorbing assembly 15 covers the housing 14 and together with the housing 14 forms a receiving cavity 141. The circuit board 16 is accommodated in the receiving cavity 141.

[0061] Furthermore, such as Figure 10 and Figure 11As shown, the side wall of the housing 14 is provided with a second embedding hole 12, which penetrates the housing 141 so that the tail end of the second ball plunger 112 is exposed in the housing 141, so that the tail end of the second ball plunger 112 can be welded to the first wire 13. The first wire 13 is electrically connected to the circuit board 16. The circuit board 16 is provided with a second wire (not shown in the figure), which is electrically connected to the lamp body 2.

[0062] Furthermore, such as Figure 12 and Figure 5 As shown, a wireless communication module 161 and a communication antenna 162 are provided on the side of the circuit board 16 away from the magnetically attached component 15. The wireless communication module 161 is used to send and / or receive wireless signals. In actual use, the user can transmit a first wireless signal with control commands through a wireless switch or mobile terminal. The wireless communication module 161 responds to the first wireless signal to control the lamp body 2 to change its brightness and color temperature. The wireless communication module 161 can also send a second wireless signal to indicate the current brightness and color temperature. The mobile terminal receives the second wireless signal and displays the brightness and color temperature externally.

[0063] Furthermore, the circuit board 16 is elongated, and the communication antenna 162 is disposed at the end of the circuit board 16. The communication antenna 162 is an external antenna and is soldered to the lower surface of the circuit board 16. When the track light 100 is installed in the magnetic track 3, the communication antenna 162 faces the indoor space to facilitate better signal radiation.

[0064] The communication antenna 162 is composed of multiple wires. One end of the communication antenna 162 is soldered to the circuit board 16, and the other end is bent in the horizontal direction to reduce the space occupied inside the connection part 1.

[0065] In some embodiments, such as Figure 9 and Figure 10 As shown, the number of first ball plungers 111 is set to four, and the four first ball plungers 111 are arranged in pairs on both sides of the connecting part 1, so that the abutment force on both sides of the connecting part 1 is more balanced; in the first direction, the first ball plungers 111 are arranged at both ends of the connecting part 1 to improve the locking stability of the first ball plungers 111 and prevent the track light 100 from falling off. The first direction is the extension direction of the connecting part 1. Figure 9 The bid is successful. Furthermore, the four first ball-head plungers 111 are at the same horizontal height to ensure that the four first ball-head plungers 111 can simultaneously engage with the engagement groove 32.

[0066] Furthermore, such as Figure 9 and Figure 10 As shown, the connecting part 1 is provided with a first insertion hole 17 at a corresponding position of each of the first ball-head plungers 111, and the first ball-head plungers 111 are inserted into the first insertion holes 17. Further, as... Figure 10 As shown, the plunger cylinder 114 of the first ball plunger 111 has a first shoulder 1111 radially protruding at one end near the ball head 113.
