Example 1

Fig. 1-3 are schematic structural views of a rail 100 according to a first embodiment of the present invention. The track 100 is a non-linear track 100, which is assembled on a mounting base 1111 and can be coupled to an electrical device (not shown) through an adapter 200 (fig. 8) to form an electrical system (not shown). The electrical device can slide within the track 100 and move the position of the electrical device within the track 100 as desired.

With continued reference to fig. 1-3, the track 100 is circular and made of a rigid material, and includes a main body 11 and a coupling element 12 disposed within the main body 11. Along the height direction of the rail 100, that is, along the direction perpendicular to the mounting base 1111, the main body 11 includes a mounting portion 111 and a frame 112 disposed away from the mounting portion 111 along the height direction, the frame 112 encloses a receiving space 113 formed with an opening 1131 facing away from the mounting portion 111, and the receiving space 113 is used for at least partially receiving the adapter 200, so that the adapter 200 can slide in the receiving space 113.

The mounting portion 111 is used for being fixedly mounted on a mounting base 1111, and the mounting base 1111 can be a ceiling, a wall or the like. In this embodiment, the mounting portion 111 is a side of the frame 112 away from the opening 1131, and a plurality of mounting holes (not shown) are disposed on the mounting portion 111, and the number of the mounting holes is set according to the length of the rail 100, which is not limited by the present invention. A plurality of mounting holes are uniformly distributed along the length direction of the rail 100, and are used for fixing the rail 100 on the mounting base 1111.

The frame 112 is provided with a mounting groove 1122 for being buckled with the coupling element 12 towards an inner side wall 1121 of the accommodating space 113, an upper surface 1123 and a lower surface 1124 of the mounting groove 1122 extend oppositely to form a pair of first buckling parts 114, a pair of second buckling parts 123 are provided at positions of the coupling element 12 corresponding to the first buckling parts 114, and the coupling element 12 is pressed and mounted into the mounting groove 1122 from the accommodating space 113 through the cooperation of the first buckling parts 114 and the second buckling parts 123. With such an arrangement, the structure of the rail 100 is simple, and the coupling element 12 is press-fitted into the fitting groove 1122 from the inner side of the frame 112 by the cooperation of the first and second snapping portions 114 and 123, so as to improve the fitting manner of the coupling element 12 and improve the fitting efficiency. This attachment method prevents the front or rear surface of the rail 100 from being inserted or inserted into the mounting groove 1122, and allows the rail 100 to be directly press-fitted into the mounting groove 1122 from the inside of the frame 112, thereby enabling interconnection of the linear rail 100 and the non-linear rail 100, and improving the butt joint performance and versatility of the rail 100.

Further, the two first fastening portions 114 are disposed opposite to each other, each first fastening portion 114 includes a first guiding inclined surface 1141 and a first position-limiting portion 1142 disposed at an acute angle, the first guiding inclined surface 1141 is disposed away from the inner sidewall 1121 relative to the first position-limiting portion 1142, and the included angle is an acute angle. That is, the two first position-limiting portions 1142 are disposed near the inner sidewall 1121 to limit and fix the coupling element 12. The first guiding inclined surface 1141 close to the upper surface 1123 is formed by extending upward from one end of the first position-limiting portion 1142 far away from the upper surface 1123 and towards the direction far away from the first position-limiting portion 1142, and the first guiding inclined surface 1141 close to the lower surface 1124 is formed by extending downward from one end of the first position-limiting portion 1142 far away from the lower surface 1124 and towards the direction far away from the first position-limiting portion 1142. This is provided to guide the coupling element 12, facilitating the press-fitting of the coupling element 12 into the mounting groove 1122 from the inside of the frame 112.

Referring to fig. 3 in conjunction with fig. 8, one coupling element 12 is provided, and is of a circular ring structure with the rail 100. A coupling member 12 is disposed in the mounting groove 1122 of the accommodating space 113 and extends along the length direction of the rail 100, and includes an insulating member 121 and a pair of conductive members 122 forming a load circuit. The conductive member 122 is embedded in the insulating member 121, and the insulating member 121 is provided with an exposure opening, so that at least a portion of one side of the conductive member 122 facing the accommodating space 113 is exposed from the exposure opening to cooperate with the electrical component 23 on the adapter 200 inserted into the accommodating space 113, thereby achieving electrical connection between the track 100 and the adapter 200.

The insulating member 121 extends along the height direction of the rail 100, two ends of the insulating member opposite to each other along the height direction respectively extend toward the inner side wall 1121 to form extending portions 1211, and the ends of the two extending portions 1211 extend toward the direction away from each other to form a pair of second locking portions 123. Each of the second locking portions 123 includes a second guiding inclined surface 1231 and a second limiting portion 1232, and the second guiding inclined surface 1231 is disposed near the inner side wall 1121 relative to the second limiting portion 1232. An included angle is also formed between the second guiding inclined surface 1231 and the second limiting portion 1232, and the included angle is an acute angle. In other words, the second position-limiting portion 1232 of the second fastening portion 123 is disposed at a position away from the inner sidewall 1121, and when the coupling element 12 is fastened and installed in the installation slot 1122, the second position-limiting portion 1232 cooperates with the first position-limiting portion 1142 to fasten the coupling element 12 in the installation slot 1122. The inclined direction of the second guiding inclined surface 1231 is parallel to the first guiding inclined surface 1141, so that when the coupling element 12 is pressed and installed into the installation groove 1122 from the inner side of the frame 112, the first guiding inclined surface 1141 and the second guiding inclined surface 1231 cooperate with each other to guide the second latching portion 123 to be latched and connected with the first latching portion 114.

Further, a pair of conductive members 122 are disposed in the insulating member 121 in parallel and spaced apart in the height direction, and the pair of conductive members 122 form a power supply loop on one side of the track 100, that is, the track 100 is a single-side power supply track 100. One side of the pair of conductive elements 122 away from the inner side walls 1121 is at least partially exposed out of the insulating element 121, that is, one side of the conductive element 122 facing the accommodating space 113 is exposed out of the insulating element 121, so as to be electrically connected to the electrical connection element 23 on the adapter 200.

In this embodiment, the insulating member 121 is a plastic extrusion member, the conductive member 122 is a copper sheet embedded in the plastic extrusion member, and the plastic extrusion member and the copper sheet are integrally formed and extruded through an extrusion process, that is, the coupling element 12 is integrally formed and disposed, so as to reduce a processing process of the coupling element 12 and improve processing efficiency.

Further, since the second locking portion 123 is formed from the end of the extension 1211 of the insulating member 121 to the direction away from each other, a gap 124 is formed between the insulating member 121 and the inner sidewall 1121 of the frame 112, that is, a gap 124 is formed between the coupling element 12 and the inner sidewall 1121, so as to facilitate heat dissipation of the coupling element 12. In addition, by providing the gap 124 between the coupling element 12 and the inner sidewall 1121 to allow a sufficient distance between the conductive member 122 and the inner sidewall 1121, the formation of an arc is avoided.

To improve the stability of the coupling element 12 being mounted in the mounting slot 1122, the gap 124 may also be filled with an adhesive to adhesively fix the coupling element 12 in the mounting slot 1122. Preferably, the adhesive may be a heat-dissipating silicone to improve the mounting stability of the coupling element 12 and facilitate heat dissipation of the coupling element 12.

It should be noted that in the present embodiment, the coupling element 12 is provided as one, and one coupling element 12 is provided at one side of the track 100 to form the track 100 with single-side power supply, in other embodiments, two coupling elements 12 may be provided, and the two coupling elements 12 are respectively installed at two sides of the track 100, that is, the two coupling elements 12 are respectively snap-installed into the installation grooves 1122 at two sides from the inner side of the frame 112 through the snap connection of the first snap part 114 and the second snap part 123. At this time, the track 100 has dual electric circuits, so as to solve the requirement of dual output independent control of the dimming and color-mixing products in the market trend, and also can be used for each independent control of the four-line three-circuit, and also can be used for combination and matching of the cut-down conductive devices 122 according to the circuit requirement of practical application. Alternatively, one of the coupling elements 12 may be a pair of control loops to improve the intelligence of the electrical system having the track 100, which is not limited by the present invention.

The above-described rail 100 structure is suitable for a general mechanically coupled rail 100 and also suitable for a magnetically coupled rail 100. When the track 100 is magnetically connected, the track 100 further includes a magnetic element 13, the magnetic element 13 and the coupling element 12 are jointly disposed in the accommodating space 113, and the magnetic element 13 is located above the coupling element 12, so as to facilitate the magnetic connection with the adapter 200 (fig. 8) entering the accommodating space 113.

An end of the coupling element 12 facing away from the opening 1131 cooperates with the frame 112 to form a receiving slot 14 for receiving the magnetic element 13. With this configuration, the coupling element 12 is used as a part of the receiving slot 14, so as to save material, reduce the cost of the track 100, and facilitate the installation of the magnetic element 13.

In the embodiment, since only one coupling element 12 is provided, a bearing portion 1125 extends from a side of the frame 112 away from the coupling element 12 to a direction close to the coupling element 12, and the bearing portion 1125, the top surface of the frame 112 and the coupling element 12 together enclose a receiving slot 14 to receive the magnetic element 13.

Since the first guiding inclined surface 1141 of the first locking portion 114 on the frame 112 is formed by extending upward from one end of the first position-limiting portion 1142 away from the upper surface 1123 and in a direction away from the first position-limiting portion 1142, the first guiding inclined surface 1141 also provides an abdicating space for mounting the magnetic element 13. When the coupling element 12 is snap-fitted into the mounting slot 1122, the coupling element 12 can be used as a part of the receiving slot 14 to limit the magnetic element 13 in the receiving slot 14. That is, along the width direction of the track 100, the width of the magnetic element 13 is greater than the distance between the bearing portion 1125 and the coupling element 12 and less than the distance between the bearing portion 1125 and the first latching portion 114. When assembling the track 100, one end of the magnetic element 13 is fixed on the bearing portion 1125, and then the coupling element 12 is pressed and installed from the inner side of the frame 112, since the distance between the coupling element 12 and the bearing portion 1125 is smaller than the width of the magnetic element 13, the coupling element 12 is used as a part of the receiving slot 14 to limit and fix the magnetic element 13 in the receiving slot 14.

In other embodiments, for example, when the rail 100 has two coupling elements 12, the bearing portion 1125 may not be provided, and the two coupling elements 12 and the top surface of the frame 112 together enclose the receiving slot 14. When assembling the track 100, one coupling element 12 is first fixed in the mounting slot 1122, one end of the magnetic element 13 is fixed on the coupling element 12, and then the coupling element 12 on the other side is mounted, so as to position and fix the magnetic element 13 in the receiving slot 14.

Further, the height and the width of the rail 100 are both less than or equal to 15mm, so that the occupied space of the rail 100 can be reduced.

Example 2

Fig. 4-5 are cross-sectional views of two mounting ways of a rail 100 according to a second embodiment of the present invention. The rail 100 of the second embodiment has substantially the same structure as the rail 100 of the first embodiment, and only the mounting portion 111 is provided differently. Therefore, only the differences in the structure are described herein, and the description of the same parts is omitted.

The mounting portions 111 of the rails 100 of the second embodiment extend upward from both ends of the frame 112 and are bent toward each other to facilitate mounting of the rails 100 to the mounting base 1111. The track 100 of the second embodiment can be installed in both a surface mount (fig. 4) and a recessed mount (fig. 5). When the rail 100 is used as the open-mounted rail 100, the mounting base 1111 may be a ceiling or a wall, and a fastener such as a screw is inserted into the mounting hole, and the head of the fastener is finally pressed against both sides of the mounting hole of the top wall 2111 and locked with the mounting base 1111, thereby fixing the rail 100 to the mounting base 1111. When the rail 100 is installed as a recessed installation rail 100, the rail 100 may be partially fixed in the installation base 1111 to reduce the occupied space of the rail 100.

Further, the width of the rail 100 of the second embodiment is less than or equal to 15mm, so that the occupied space of the rail 100 can be reduced.

Example 3

Referring to fig. 6 in conjunction with fig. 3, a track 100 according to a third embodiment of the present invention is shown. The basic structure of the track 100 of the third embodiment is substantially the same as that of the track 100 of the first embodiment, except that the track 100 of the third embodiment is a circular arc track 100. Therefore, only the differences of the structures are described herein, and the description of the same parts is omitted.

The circular arc shaped track 100 comprises a circular arc shaped main body portion 11, a circular arc shaped magnetic element 13 and a circular arc shaped coupling element 12. When the circular arc rail 100 needs to be assembled, the circular arc magnetic element 13 is first placed in the receiving groove 14, and then the circular arc coupling element 12 is pressed from the inner side of the frame 112 into the mounting groove 1122. That is, the coupling element 12 is pressed from the accommodating space 113 to the mounting groove 1122 through the cooperation of the first latching portion 114 and the second latching portion 123. Thus, the non-linear rail 100 can be easily assembled.

Example 4

Referring to fig. 7 in conjunction with fig. 3, a track 100 according to a fourth embodiment of the present invention is shown. The basic structure of the track 100 of the fourth embodiment is substantially the same as that of the track 100 of the first embodiment, except that the track 100 of the fourth embodiment is a straight track 100 (i.e., a line-type track 100). Therefore, only the differences in the structure are described herein, and the description of the same parts is omitted.

The linear rail 100 comprises a linear body portion 11, a linear magnetic element 13 and a linear coupling element 12. When the linear rail 100 needs to be assembled, the linear magnetic element 13 is first placed in the receiving slot 14, and then the linear coupling element 12 is pressed from the inner side of the frame 112 to be installed in the installation slot 1122. That is, the coupling element 12 is pressed from the accommodating space 113 to the mounting groove 1122 through the cooperation of the first latching portion 114 and the second latching portion 123. Thus, the assembly method of the linear rail 100 is improved, and the assembly efficiency of the linear rail 100 is improved.

It should be noted that, since in the present invention, the magnetic element 13 is fixed by the coupling element 12, the coupling element 12 is pressed inward from the inner sidewall 1121 of the rail 100 by the cooperation of the first locking portion 114 and the second locking portion 123 to be fixed in the mounting slot 1122. The installation mode improves the assembly mode of the conventional track 100, and at least two tracks 100 can be assembled in a cascade mode according to the requirements of users, namely splicing and combining of the linear track 100 and the non-linear track 100 can be realized. In addition, in the splicing of the linear track 100 and the non-linear track 100, the coupling element 12 can be directly shared, and the electrical connection between the linear track 100 and the non-linear track 100 is not required to be realized through a connecting member with a conductive function, so that the number of contacts for electrical connection is reduced, and the stability and the safety of the electrical connection of the cascade track 100 are improved.

Referring to fig. 8-15 in conjunction with fig. 1-7, the present invention provides an adapter 200, wherein the adapter 200 is configured to be mechanically and electrically connected to the rail 100 for coupling electrical equipment to the rail 100.

The magnetic attachment member 22 is disposed adjacent the top wall 2111 and magnetically attaches to the magnetic attachment member of the track 100 through the top wall 2111. The power connection element 23 and the glass bead assembly 25 are respectively disposed on the first side wall 2112 and the second side wall 2113, and at least partially exposed out of the first side wall 2112 and the second side wall 2113, so that one side of the adapter 200 and the rail 100 realize side power supply, and the other side realizes an anti-drop design through the glass bead assembly 25, thereby improving the stability of connection between the adapter 200 and the rail 100.

In this embodiment, the housing 21 includes a cover 212 and a slot 211, the slot 211 is disposed above the cover 212, a top wall 2111 of the housing 21 is a top wall 2111 of the slot 211, a first side wall 2112 and a second side wall 2113 of the housing 21 are a first side wall 2112 and a second side wall 2113 of the slot 211, and a bottom wall of the housing 21 is the cover 212.
