As shown in Figures 1 to 13, a rail light includes an electric magnetic guide rail assembly for driving the rail light to slide in the rail 1, a first for controlling the illumination angle of the rail light in the horizontal direction. The magnetic rotating assembly 2, the electric box 3 and the lamp body 4, the electric magnetically attracting guide rail assembly 1 and the electric box 3 are connected by the first magnetic rotating assembly 2, the lamp body 4 and the electric box 3 electrical connection;

The electric magnetic guide rail assembly 1 includes a guide rail 11 and a guide rail box 12, the guide rail box 12 is slidably arranged in the guide rail 11, and the top of the guide rail box 12 is provided with a second guide rail 11 slidable along the guide rail 11. A roller 121, the guide rail box 12 is provided with a driving member 122 for driving the first roller 121 to rotate;

The inner side of the guide rail 11 is provided with a magnetic member 111 parallel to it. The first roller 121 is made of a magnetic material and is magnetically attracted to the magnetic member 111. The first roller 121 can be mounted on the drive member 111. Driven by 122, it slides along the magnetic member 111.

As shown in FIGS. 2 to 7, the electric magnetic guide rail assembly 1 includes the guide rail 11 and the guide rail box 12, and the guide rail box 12 includes a first roller 121 arranged on the top of the guide rail box 12. The first roller 121 can be composed of multiple sets of rollers arranged at intervals, or can be set as a single roller. The cost of using a single roller is lower, and the magnetic attraction effect of using multiple sets of rollers and the magnetic member 111 is better. Used when the light source installed at the lower end of the box 12 is heavy, so that the guide rail box 12 can smoothly slide in the guide rail 11, so as to adjust the position of the electric magnetic guide rail assembly 1 and the matched light source The inner part of the guide rail box 12 is also provided with a driving member 122, which provides the power of the first roller 121 to reciprocate, so that the first roller 121 can slide in the guide rail 11 by itself. To adjust the specific position of the guide rail box 12, the user does not need to manually adjust the position of the guide rail box 12. When the electric magnetic guide rail assembly 1 is installed at a high position, it is very convenient to use. The inner side of the guide rail 11 is also provided with a detachable magnetic member 111, the magnetic member 111 is arranged in cooperation with the first roller 121 made of magnetic material, and the first roller 121 is slidably arranged on the At the lower end of the magnetic member 111, when the guide rail box 12 needs to stop during the movement of the first roller 121, when the driving member 122 does not provide power to the first roller 121, the magnetic force attracts The first roller 121 can realize rapid stop and positioning without sliding part of the distance inside the guide rail 11 due to inertia, and the guide rail box 12 and the light source installed at its lower end with this arrangement will not fall due to gravity , The magnetically connected first roller 121 and the magnetic member 111 have a very long service life. After a long period of use, there will be no sliding failure due to wear between the components. In addition, under high temperature conditions, the The magnetic attraction of the first roller 121 and the magnetic member 111 will not fail, and there will be no phenomenon that the high-temperature softening of the components causes the failure of the fixing method to cause the lamp source to fall. The first roller 121 and the magnetic member 111 All 111 can be made of iron sheets or other magnetic materials, and the driving member 122 can be driven by a motor or an air cylinder.

In this embodiment, the guide rail 11 is arranged horizontally, that is, the guide rail 11 is parallel to the ground. At this time, the first magnetic rotation assembly 2 can be used to control the illumination angle of the guide rail lamp light in the horizontal direction; In an example, the guide rail 11 is arranged perpendicular to the ground, that is, when the guide rail 11 is installed vertically, the first magnetic rotation assembly 2 controls the illumination angle of the guide rail lamp in the vertical direction (that is, the direction perpendicular to the ground) .

Furthermore, both sides of the guide rail box 12 are provided with a retractable second roller 123, and the inner side of the guide rail 11 is provided with a first groove 112 that is matched with the second roller 123.

In addition to the adsorption effect of the first roller 121 and the magnetic member 111, there is also a fixing effect of the second roller 123. The second roller 123 is clamped and arranged in the first groove 112 on the inner wall of the guide rail 11. And can slide freely in the first groove 112, which relieves the gravity generated by the guide box 12 and its internal installation components, and prevents the gravity of the light source installed at the lower end of the guide box 12 Too large, greater than the situation when the first roller 121 and the magnetic member 111 fall due to the magnetic attraction force, and the two sets of rollers, the first roller 121 and the second roller 123, are used in conjunction with each other. The sliding and stopping processes of the electric magnetic guide rail assembly 1 when it moves by itself are smoother.

Further, the inner side of the top end of the guide rail 11 is provided with a second groove 113;

The second groove 113 is embedded with the magnetic member 111, and the top end of the first roller 121 is magnetically attracted to the magnetic member 111;

Or, the magnetic member 111 is arranged parallel to the inner side wall of the second groove 113, and the side wall of the first roller 121 and the magnetic member 111 are magnetically attracted together.

This technical solution provides two different ways of setting the magnetic member 111 and the first roller 121. The first type: as shown in FIG. 4, the guide rail 11 is provided with a second groove 113, the magnetic member 111 is embedded in the second groove 113, and the magnetic member 111 is located in the second groove 113. The top end of a roller 121, the first roller 121 is magnetically connected to the magnetic member 111 through the top end, and the first roller 121 can slide along the lower end of the magnetic member 111, due to the magnetic adsorption of the two It is convenient for the first roller 121 to stop positioning during the sliding process, and the first roller 121 is relatively smooth during the sliding process.

The second type: as shown in FIG. 5, the magnetic member 111 is arranged parallel to the inner side wall of the second groove 113, and the side wall of the first roller 121 is magnetically attracted to the magnetic member 111, so The top end of the first roller 121 can roll back and forth along the second groove 113, and the side wall is magnetically connected to the magnetic member 111. Both sides of the first roller 121 are magnetically attracted, and the two The contact area of the person is larger, which makes the positioning of the first roller 121 faster and more convenient when it stops at the designated place, and the load-bearing effect is better.

Further, an insulating pad 114 is embedded in the inner wall of the guide rail 11, a metal strip 1141 is embedded in the inner side of the insulating pad, and contact elastic pieces matched with the metal strip 1141 are provided on both sides of the guide rail box 12 125. The contact elastic piece 125 is electrically connected to the metal strip 1141.

The inner side of the guide rail 11 is also provided with a "T"-shaped groove, and the inside of the "T"-shaped groove is provided with an insulating pad 114. Since the insulating pad 114 needs to be fixed with a metal strip 1141 for energization, it adopts The insulating material prevents the guide rail 11 from conducting electricity when the metal strip 1141 is energized, and it is prone to safety accidents when the user accidentally touches the metal strip 1141. The metal strip 1141 is connected to an external power source and is connected to the guide box 12 The contact elastic pieces 125 on the outside are arranged in cooperation to realize the electrical connection between the metal strip 1141 and the rail box 12 and the external power supply, and are the driving parts 122 and the external power supply installed in the rail box 12 The light source at the lower end of the rail box 12 provides power.

Further, the bottom end of the guide rail box 12 is provided with a toggle portion 124 for controlling the expansion and contraction of the second roller 123.

Since the internal components of the electric magnetic guide rail assembly 1 may fail after long-term use, it is necessary to replace each component in time. Specifically, the toggle portion 124 can control the “shrinkage of the second roller 123”. "And "extend", as shown in FIG. 6, when the user waves the toggle portion 124 to be perpendicular to the longitudinal direction of the rail box 12, the second roller 123 moves from the inside of the rail box 12 In the extended state, the second roller 123 is clamped with the first groove 112 to realize the further load-bearing of the electric magnetic guide rail assembly 1. As the first roller 121 and the magnetic member 111, coupled with the engagement of the second roller 123 and the first groove 112, the guide rail box 12 is firmly fixed inside the guide rail; as shown in Figure 7, when the user When the toggle portion 124 is moved to be parallel to the longitudinal direction of the guide rail box 12, the second roller 123 shrinks to the inside of the guide rail box 12, because the width of the guide rail box 12 is smaller than that of the guide rail box 12 The width of the guide rail 11, therefore, when the second roller 123 loses its engagement with the first groove 112, the user only needs to overcome the magnetic adsorption effect of the first roller 121 and the magnetic member 111. It is very convenient to take out the entire electric magnetic guide rail assembly 1 from the guide rail 11 for component replacement and maintenance. After the replacement is completed, the guide rail box 12 is put back into the guide rail 11, and the dial is adjusted. The moving part 124 enables the second roller 123 to be engaged with the first groove 112 again.

Further, as shown in FIGS. 8-9, the first magnetic rotation assembly 2 includes a motor fixing member 21, a driving motor 22, a driving gear 23, a driven gear 24, a DC plug 25 and a magnetic buckle 26; The motor fixing member 21 is provided with a shaft hole. The driving motor 22 and the driving gear 23 are respectively located on both sides of the motor fixing member 21. The output shaft 221 of the driving motor 22 passes through the shaft hole and is connected to the shaft hole. The driving gear 23 is matched in transmission, so that the driving gear 23 can be rotated under the drive of the driving motor 22; the driven gear 24 and the motor fixing member 21 are detachable plug-in connection, when the two When inserted and fixed, the driven gear 24 meshes with the driving gear 23, so that the driven gear 24 can rotate with the rotation of the driving gear 23; the DC plug 25 includes a DC male plug 251 and a DC female plug 252, both One of them is fixed at the center of the driven gear 24, and the other is fixed at the corresponding position of the motor fixing member 21, so that both are inserted when the driven gear 24 and the motor fixing member 21 are inserted and fixed. The magnetic buckle 26 includes at least two pieces of magnetic material that can absorb each other, one of which is arranged on the driven gear 24, and the other is arranged on the motor fixing member 21 correspondingly.

In this embodiment, the DC male connector 251 is located on the side of the driving motor 22, and the DC female connector 252 is located on the side of the driven gear 24; of course, the reverse is also possible.

In this embodiment, the side of the driven gear 24 facing the motor fixing member 21 has a boss for plugging and fixing, and the side of the motor fixing member 21 facing the driven gear 24 is also provided with A groove corresponding to the boss. When inserting and fitting, the boss is inserted into the groove, and the driven gear 24 is meshed with the driving gear 23. When the driving motor 22 rotates, the driving gear 23 is on the output shaft of the driving motor 22. Drive down rotation and drive the driven gear 24 to rotate. When the driven gear 24 is fixed on the electrical box 3, the electrical box 3 will follow the rotation of the driven gear 24 Rotate to realize the adjustment of the beam angle.

The magnetic buckle 26 uses magnetic attraction to make the driven gear 24 and the motor fixing member 21 more closely fit without falling off. At the same time, an electromagnetic buckle is used to rotate the driven gear 24 The impact is small. The driven gear 24 only needs to overcome the static friction between the boss and the groove. Although the static friction between the two will increase under the action of the magnetic buckle 26, the magnetic force acts after all. The direction is perpendicular to the direction of the knob when rotating, and the power requirement of the driving motor 22 is correspondingly low.

In this embodiment, the driven gear 24 is provided with a first slot 242 for loading the magnetic material, and the motor fixing member 21 is also provided with a second slot for loading the magnetic material. 213. The shape of the card slot corresponds to the shape of the magnetic material. Usually we make the magnetic material into a ring, and the central ring hole is used to pass through the DC male plug 251 or the DC female plug 252. In this embodiment, For better positioning, a guide post is provided in the second slot 213 on the motor fixing member 21, and the outer diameter of the guide post is the same as the diameter of the ring hole of the ring-shaped magnetic material, so that the magnetic ring It can be inserted into the guide post for positioning. At the same time, the guide post has a hollow pin hole, the DC male plug 251 passes through and extends out of the pin hole, and the DC female plug 252 also passes through another piece of magnetic The ring hole in the center of the material, so that the DC male plug 251 and the DC female plug 252 are inserted and connected during insertion and mating.

In this embodiment, the magnetic material used is a neodymium iron boron magnet. The neodymium iron boron magnet has the characteristics of small size and strong magnetism, and two of them can be neodymium iron boron magnets, or one of them is neodymium iron boron magnet and the other is magnetic metal. It needs to be explained here that when the magnetic material is selected as two magnets, it is necessary to pay attention that the opposite side is the opposite magnetic pole, so as to ensure that they are attracted to each other.

In this embodiment, the driving motor 22 used is a stepping motor. When the stepper motor is not overloaded, the speed and stop position of the motor only depend on the frequency and number of pulses of the pulse signal, and are not affected by load changes. This facilitates the realization of automatic control, for example, the automatic adjustment of the beam angle can be conveniently realized by using a remote control device to control the rotation of a stepping motor.

Further, as shown in FIG. 1, it also includes a second magnetic rotation assembly 5. The second magnetic rotation assembly 5 has the same structure as the first magnetic rotation assembly 2, and the lamp body 4 is connected to the electrical The side ends of the box 3 are rotatably connected by the second magnetic rotation assembly 5.

The structure of the second magnetic rotation assembly 5 is the same as the structure of the first magnetic rotation assembly 2. In actual applications, the shapes of some parts may be different, but the overall structure is the same and the principle is the same. Not repeat them one by one. The second magnetic rotation assembly 5 is fixed on the side end of the electrical box 3, and the driven gear is fixed on the lamp body 4. When the second magnetic rotation assembly 5 is in operation, the lamp body 4 It can be rotated 360° around the horizontal line to adjust the position and angle of the light.
