[0027] The present application is further described in detail below in conjunction with the accompanying drawings.

[0028] Combination Figure 2 and Figure 4 The present application provides a track assembly 100, which is used to adapt to the lamp 200. The track assembly 100 includes a guide rail body 110 and a first magnet 120. The guide rail body 110 is provided with a first snap-fit ​​structure 130; the first magnet 120 is connected to the guide rail body 110; wherein the first magnet 120 is used to be magnetically connected to the lamp 200, and the guide rail body 130 is used to snap-fit ​​with the lamp 200 through the first snap-fit ​​structure 130.

[0029] In the embodiment of the track assembly 100 proposed in the present application, the guide rail body 110 adopts an integrally molded structure, and the materials used include plastic, rubber, ceramic, metal, etc. In the embodiment of the present application, the guide rail body 110 adopts non-metallic materials such as plastic and rubber, and injection molding or extrusion molding is adopted in the process, which is cost-effective, simple in process, and suitable for large-scale production. The first magnet 120 can be selected from magnetic metal materials such as iron, cobalt, and nickel, or materials with magnetic properties such as magnets. In one embodiment, the first magnet 120 is an iron sheet. The first magnet 120 and the guide rail body 110 can be bonded, embedded, or snapped together, which is simple to assemble and easy to install; the first snap structure 130 is arranged on the guide rail body 110 as a further fixed connection structure.

[0030] The track assembly 100 and the lamp 200 in the lighting device 300 of the present application have a relatively simple structure, and are relatively convenient and easy to operate during installation. The first magnet 120 of the track assembly 100 is connected to the guide rail body 110. When installing the lamp 200 on the track assembly 100, the lamp 200 provided with the second magnet 250 is attracted by the first magnet 120 and connected to the guide rail body 110, which can be used to preliminarily locate the lamp 200 and facilitate accurate finding of the connection position; then the installer presses the lamp 200, and the first buckle structure 130 is snapped with the lamp 200 to complete the assembly, and the snap connection further determines the installation position of the lamp 200, preventing the lamp 200 from falling off due to unstable magnetic connection, thereby improving the connection stability and safety of the product.

[0031] In some embodiments, the guide rail body 110 includes side portions 111 and a middle portion 112 , the side portions 111 are disposed on both sides of the middle portion 112 , the middle portion 112 is provided with a mounting groove 140 , and the first magnet 120 is disposed in the mounting groove 140 .

[0032] In some embodiments of the present application, the lamp 200 is equipped with a second magnet 250, the second magnet 250 is a magnet, the first magnet 120 is an iron sheet, and a mounting groove 140 is provided on the guide rail body 110 near the middle, that is, the middle part 112, and the first magnet 120 is inserted into the mounting groove 140, so that the magnet and the iron sheet can be magnetically connected, which is simple and convenient. The first magnet 120 is provided in the middle part 112, which facilitates the lamp 200 to accurately find the connection point; the contact surface between the lamp 200 and the middle part 112 is a plane, the contact surface is large, and it is not easy to shake, so as to prevent the lamp 200 from tipping over, thereby improving the safety of the product.

[0033] It is worth noting that the selection of the first magnet 120 needs to be adapted to the lamp 200. For example, when the second magnet 250 on the lamp 200 is a magnet, the first magnet 120 can be selected from magnetic metals such as iron, cobalt, nickel, or a magnet; when the second magnet 250 of the lamp 200 is an iron block, or the outer shell of the lamp 200 is made of iron, the first magnet 120 can be selected from materials with magnetic attraction properties such as a magnet.

[0034] In some embodiments, the side portion 111 includes a supporting portion 1111 and a blocking portion 1112, the supporting portion 1111 is connected to the middle portion 112, the blocking portion 1112 is connected to one end of the supporting portion 1111, and the blocking portion 1112 and the supporting portion 1111 are together enclosed to form a first snap-fit ​​structure 130 of a slot-type.

[0035] Figure 2 The rail body 110 in the track assembly shown is also called a surface-mounted rail, which is an embodiment of the rail body 110. The surface-mounted rail has a simple structure and is convenient for installing the lamp 200. Along the direction pointed by the side portion 111, the rail body 110 is provided with a blocking portion 1112, and the lamp 200 is installed on the rail body 110. The support portion 1111 provides a support site for the lamp 200; when the magnetic attraction is unstable and the lamp 200 tends to fall off, the blocking portion 1112 will prevent the lamp 200 from leaving the rail body 110, thereby preventing the lamp 200 from falling off due to unstable magnetic connection, thereby improving the connection stability and safety of the product.

[0036] like Figure 4 As shown, in some embodiments, the guide rail body 110 in the track assembly is a concealed track, and the side portion 111 of the concealed track includes a support portion 1111 and a first sub-portion 1113, the support portion 1111 is connected to the middle portion 112, and the first sub-portion 1113 is connected to the support portion 1111. In this embodiment, a long plate-shaped portion is extended at the connection between the support portion 1111 and the blocking portion 1112, and the portion is the first sub-portion 1113. The middle portion 112, the support portion 1111 and the first sub-portion 1113 together form a surrounding groove 170, and the surrounding groove 170 is used to limit the position of the lamp 200.

[0037] Regarding the concealed track, it should be supplemented that the assembly form between the lamp 200 and the guide rail body 110 can be a fully concealed form or a semi-concealed form. The so-called fully concealed installation means that after the lamp 200 is installed on the guide rail assembly, the side wall of the lamp 200 is completely surrounded by the side wall of the guide rail body 110, and the height of the side wall of the guide rail body 110 can also exceed the side wall of the lamp 200 (that is, the first sub-section 1113 completely covers the side wall of the lamp 200). The advantage of fully concealed installation is that the lamp 200 is completely embedded in the guide rail body 110, and the friction generated by the side walls of the lamp 200 and the guide rail body 110 can improve the installation stability of the lamp 200 and prevent the lamp 200 from slipping. In addition, since the side wall of the guide rail body 110 limits the propagation direction of the light, fully concealed installation can also achieve directional lighting, which is suitable for specific work occasions. The so-called semi-concealed installation means that after the lamp 200 is installed and embedded in the guide rail body 110, the side wall of the lamp 200 is partially exposed from the side wall of the guide rail body 110 (that is, the first sub-section 1113 covers part of the side wall of the lamp 200). The advantage of semi-concealed installation is that the installation stability of the lamp 200 is good, and since it is not blocked by the side wall of the guide rail body 110, a wide range of lighting can be achieved.

[0038] In addition, the concealed track (including fully concealed and semi-concealed) also has the following advantages: the groove 170 limits the plug-in direction of the lamp 200, thereby improving the installation success rate of the lamp 200; the setting of the groove 170 also prevents the lamp 200 from shaking due to impact, that is, reduces the probability of the lamp 200 abnormally detaching from the guide rail body 110; at the same time, the first sub-section 1113 can also protect the outer shell of the lamp 200, prevent the outer shell of the lamp 200 from being damaged by impact, and improve the safety and service life of the product.

[0039] Compared with the concealed track, the surface track omits the first sub-section 1113, has a simpler structure, lower cost, and is easy and quick to install. After the lamp 200 is installed on the guide rail body 110 of the surface track, the side wall of the lamp 200 is exposed outside the guide rail body.

[0040] In some embodiments, the side portion 111 includes a second sub-portion 1114, which is connected to the first sub-portion 1113. The second sub-portion 1114 can be used for installation in a specific position, and can also be used as a grip during disassembly to facilitate the connection or separation of the lamp 200 and the track assembly 100.

[0041] Considering the inconvenience of disassembling the lamp 200 arranged on the concealed track, the second sub-section 1114 is provided, combined with Figure 3 and Figure 4The second sub-portion 1114 is vertically connected to the first sub-portion 1113. When the lamp 200 needs to be disassembled, hold the second sub-portion 1114 with both hands and bend it outward with force. The side portion 111 and the blocking portion 1112 are bent outward accordingly. The size of the first buckle structure 130 becomes larger, and the lamp 200 can be smoothly disassembled.

[0042] In some embodiments, the track assembly 100 further includes a conductive member 160, the track assembly 100 is provided with a sliding groove 150, the conductive member 160 is slidably fitted in the sliding groove 150, and the conductive member 160 is used to be electrically connected to the lamp 200. The sliding groove 150 in this embodiment is connected to the first buckle structure 130, and the two can be separately provided in other embodiments.

[0043] One end of the conductive member 160 is connected to the lamp 200, and the other end is connected to a power source. After the lamp 200 is installed on the track assembly 100 and the power source is turned on, the lamp 200 can be used for lighting. Since the extension direction of the conductive member 160 is consistent with the direction of the sliding groove 150, the lamp 200 and the conductive member 160 are electrically connected, and therefore the lamp 200 can be moved along the direction of the sliding groove 150, thereby expanding the installation location and the lighting area.

[0044] Combination Figure 5 The present application provides a lamp 200, which is used to adapt to the track assembly 100, and the lamp 200 includes a bottom shell 210, a second magnet 250 and a second buckle structure 220. The second magnet 250 is provided on the bottom shell 210, and the second buckle structure 220 is connected to the bottom shell 210, wherein the second magnet 250 is used to be magnetically connected to the track assembly 100, and the second buckle structure 220 is buckled with the track assembly 100.

[0045] It is worth noting that the first buckle structure 130 and the second buckle structure 220 cooperate with each other, so the specific structural forms can be interchanged, that is, when the first buckle structure 130 is in the form of a slot, the second buckle structure 220 is in the form of a buckle; when the first buckle structure 130 is in the form of a buckle, the second buckle structure 220 is in the form of a slot. The specific design style needs to be adjusted according to the use scenario and use requirements, and is not strictly limited here.

[0046] The bottom shell 210 provides an installation position for the components in the lamp 200, the second magnet 250 provides magnetic attraction, and the second snap-on structure 220 further fixes the position of the lamp 200. When the lamp 200 is installed on the track assembly 100, the second magnet 250 and the first magnet 120 mentioned above attract each other, the lamp 200 is connected to the track assembly 100, and then the lamp 200 is inserted into the track assembly 100. The second snap-on structure 220 is snapped with the track assembly 100, which prevents the lamp 200 from being separated from the track assembly 100 due to unstable magnetic attraction, thereby improving the accuracy of installation and the safety of the product. Similar to the above, the selection of the second magnet 250 needs to be compatible with the first magnet 120. For example, when the first magnet 120 selects an iron sheet, the second magnet 250 selects a magnet; when the first magnet 120 selects a magnet, the second magnet 250 selects a magnetic material such as a magnet or an iron sheet. The second buckle structure 220 can be a buckle, the first buckle structure 130, a buckle hole or the like.

[0047] In some embodiments, the bottom shell 210 includes a limiting portion 213, the limiting portion 213 encloses a limiting groove 230, and the second magnet 250 is disposed in the limiting groove 230. The limiting portion 213 and the bottom shell 210 can be integrally formed for easy production; or they can be produced separately and then assembled. Figure 5 The limiting portion 213 has a limiting groove 230 formed in the middle thereof. The side wall of the limiting portion 213 is provided with a hook structure to prevent the second magnet 250 from falling off. The second magnet 250 is fitted in the limiting groove 230 and is not easy to shake. The hook structure prevents the second magnet 250 from separating from the limiting portion 213, thereby preventing the second magnet 250 from separating from the bottom shell 210 and causing collisions, thereby improving the safety and service life of the lamp 200. In other embodiments, the limiting portion 213 can be designed as a box type, and the second magnet 250 is directly inserted into the limiting groove 230 from the side of the limiting portion 213.

[0048] In some embodiments, the bottom shell 210 includes a first portion 211 and a second portion 212, the first portion 211 connects the two ends of the second portion 212, and the first portion 211 is provided with a recessed groove 240, which is used as a force point when assembling the lamp 200. Considering that the lamp 200 is in a long strip shape and is inconvenient to hold and install, recessed grooves 240 are provided at both ends of the lamp 200. For a lamp 200 of a smaller size, only one hand needs to abut the first portion 211, and the finger is inserted into the recessed groove 240, so that the lamp 200 can be plugged in and out, thereby assembling the lamp 200; for a lamp 200 of a larger size, it is necessary to abut the first portions 211 at both ends respectively to cooperate in the plugging and unplugging actions; in other embodiments, the recessed grooves 240 can also be provided on the front and rear side walls of the lamp 200, or a pull ring structure can be designed on the first portion 211.

[0049] In some embodiments, the lamp 200 further includes a circuit board 260 and a conductive pin 270 . The circuit board 260 is disposed in the bottom shell 210 , and the circuit board 260 is provided with a conductive pin 270 that passes through the bottom shell 210 .

[0050] Combination Figure 5 It can be understood that the normal use of the lamp 200 requires a power supply and a circuit device, so a circuit board 260 is provided on the bottom shell 210, and the circuit board 260 receives and processes electrical energy and finally converts the electrical energy into light energy; as a part for the lamp 200 to obtain energy from the outside, the conductive pin 270 is connected to the circuit board 260, and the conductive pin 270 is penetrated through the bottom shell 210, and the conductive pin 270 transmits the electrical energy of the power supply to the circuit board 260.

[0051] Specifically, when the lamp 200 is installed on the track assembly, the conductive pin 270 is connected to the conductive member 160, and the electrical energy of the conductive member 160 is transmitted to the circuit board 260. The circuit board 260 receives and processes the electrical energy and finally converts the electrical energy into light energy.

[0052] Combination Figure 1 and Figure 3 The present application also proposes a lighting device 300, which includes any of the above-mentioned track components 100 and any of the above-mentioned lamps 200, the first magnet 120 and the second magnet 250 are magnetically connected, and the second snap-fit ​​structure 220 is snap-fitted with the first snap-fit ​​structure 130. The first magnet 120 and the second magnet 250 attract each other, which facilitates finding the accurate installation position between the lamp 200 and the track component 100, and the snap-fitting of the second snap-fit ​​structure 220 and the first snap-fit ​​structure 130 prevents the lamp 200 and the track component 100 from being separated due to unstable magnetic attraction, further improving the stability of the connection between the lamp 200 and the track component 100, and improving the connection stability of the product.
