Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of lamp control, especially an electric control double-joint lamp that is easy to adjust. BACKGROUND

[0002] In modern lighting design, track lights, recessed spotlights, and ceiling lights are widely popular among consumers due to their unique aesthetic designs and efficient lighting effects. These lamps are widely used in clothing retail, home decoration, museum exhibitions, and other scenarios to meet the lighting needs of different occasions. Traditional lamp structures are usually composed of a base, a connecting rod, and a lamp holder. The connecting rod is hinged at both ends to the base and the lamp holder, allowing users to manually adjust the illumination direction of the lamp to a certain extent after installation.

[0003] However, the existing lamp design has several shortcomings:

[0004] 1. Once the lamp is installed, its illumination area is fixed. Since the lamp is usually installed at a high position, if the lighting angle or range needs to be adjusted, the user must use a ladder or other elevation tool, which not only increases the operation difficulty but also may cause safety hazards. In addition, frequent disassembly and assembly processes may damage the lamp or affect its service life.

[0005] 2. Although most lamps support 360° horizontal rotation, there is no effective rotation position memory mechanism. Therefore, after each adjustment, the lamp cannot automatically return to the previous set angle, and unlimited rotation can easily cause internal wire kinking, thereby interfering with the normal operation of the lamp. In extreme cases, it may even cause wire breakage, causing electrical failure or safety risks.

[0039] To make the technical problem to be solved, the technical solution, and the beneficial effects of this utility model clearer and more understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0040] Please see Figures 1 to 7 This is a preferred embodiment of an easily adjustable electrically controlled double-joint lamp, comprising a base 10, a horizontal rotating connecting structure 90, a connecting rod 20, a lamp holder 30, a first motor 40, a second motor 50, a controller 60, a magnetic contact 70, and a magnetic contact 80, wherein:

[0041] like Figure 1 , 2 As shown, the base 10 serves as the connection base between the lamp and the fixed surface, and a hollow installation area 11 is formed on its inner side;

[0042] Combination Figure 2 , 3 4. Description of the horizontal rotational connection structure 90 of the lamp:

[0043] In this embodiment, the horizontal rotating connection structure 90 is arranged at the bottom of the mounting area 11, and includes a support 91 at the middle and a rotating member 92 horizontally connected around the periphery of the support 91, the lower end of the rotating member 92 protrudes from the base 10 and forms a connecting end 93;

[0044] Specifically, the support 91 at the middle is a bearing, the inner side of the bearing is a fixed inner ring 911, and the outer side is a rotating outer ring 912, and the rotating outer ring 912 is smoothly rotated relative to the fixed inner ring 911 in the horizontal direction through the ball structure 913 between the fixed inner ring 911 and the rotating outer ring 912. The rotating member 92 is a first driven gear with a mounting gap on the inner side, and the size of the mounting gap is designed to be just able to be clamped with the outer periphery of the rotating outer ring 912, so as to be fixed on the outer peripheral wall surface of the rotating outer ring 912, and the first driven gear is smoothly rotated in the horizontal plane.

[0045] In order to realize the rotating connection of the connecting rod 20, a ring structure is formed at the lower end of the first driven gear, that is, the connecting end 93, which is distributed around the periphery of the mounting gap, and the upper end of the connecting rod 20 is fixedly connected with the connecting end 93, so as to realize the circumferential rotation of the connecting rod 20 with the connecting end 93 and the first driven gear.

[0046] In addition, in order to realize the accommodation, a circular through slot 12 is arranged at the inner bottom of the mounting area 11 at the position of the mounting gap, and the diameter of the through slot 12 is adapted to the outer diameter of the connecting end 93, so as to facilitate the connecting end 93 to pass through the base 10.

[0047] In order to realize the fixation of the bearing and the magnetic contact 1 70, the bearing is fixedly connected with the bottom of the mounting area 11 through the fixing piece 13 arranged at the upper end of the bearing. Specifically, in this embodiment, the end of the fixing piece 13 is locked and fixed to the inner bottom surface of the mounting area 11, and the upper end thereof is bent and extended to the fixed inner ring 911 of the bearing and the upper end of the magnetic contact 1 70. The fixed inner ring 911 and the magnetic contact 1 70 are fixed through the fixing piece 13, so as to provide a stable support basis for the first driven gear. In this embodiment, the fixing piece 13 is uniformly provided with three groups around the periphery of the first driven gear, and the number thereof can be increased according to the needs, which is not limited herein.

[0048] The first motor 40 is fixedly arranged on the inner bottom of the mounting area 11 through the support structure 42, and the output end of the first motor 40 is vertically directed to the bottom surface of the mounting area 11, and the first driving gear 41 is integrally fixed on the output end of the first motor 40. The first driving gear 41 is just engaged with the first driven gear, so that the first driving gear 41 and the first driven gear can be driven to rotate through the rotation of the first motor 40, so that the connecting rod and the lamp holder 30 can follow the rotation of the first driven gear and realize stable rotation in the horizontal plane.

[0049] AsFigure 1 , 2 As shown in Figure 3, the connecting rod 20 is cylindrical in shape. The upper end of the connecting rod 20 is fixed to the connecting end 93 to achieve horizontal rotation relative to the base 10. The lower end of the connecting rod 20 forms the first connecting part 22, and the inner side of the connecting rod 20 forms a vertically penetrating mounting cavity 21.

[0050] Specifically, the size of the connecting cavity is designed to be compatible with the outer diameter of the connecting end 93, and a corresponding stepped groove 211 is formed to facilitate the limiting and stopping of the connecting rod 20 after it is inserted into the connecting end 93. In addition, in order to further fix the connecting rod 20 and the connecting end 93, the connecting end 93 is provided with two first connecting holes 931 around its periphery, and the side wall of the connecting rod 20 and the upper end of the mounting cavity 21 are provided with a second connecting hole 212 opposite to the position of the first connecting holes 931. By locking the corresponding locking bolts into the first connecting holes 931 and the second connecting holes 212, the connecting rod 20 and the connecting end 93 can be further tightened, so that the connecting rod 20 can rotate stably with the rotation of the connecting end 93.

[0051] like Figure 1 , 7 As shown, the lamp holder 30 has an inner lamp bead 31 for lighting. The upper end of the lamp holder 30 forms a pair of second connecting parts 32. A pivot shaft 33 is provided between the two second connecting parts 32. The pivot shaft 33 is pivotally connected to the first connecting part 22.

[0052] Specifically, in combination Figure 6 A number of plate-shaped heat sinks 34 are vertically fixed on the upper surface of the lamp holder 30. Based on two parallel heat sinks 34, they serve as the second connecting parts 32. The lower end of the connecting rod 20 extends integrally along both sides of its opening diameter to form a pair of first connecting parts 22. The first connecting parts 22 are also plate-shaped structures. The distance between the two second connecting parts 32 is adapted to the distance between the two first connecting parts 22. The pivot shaft 33 is fixed between the two second connecting parts 32 and passes through the two first connecting parts 22 respectively. The area between the two first connecting parts 22 forms a connection area facing the mounting cavity 21. The pivot shaft 33 is fixed with a coaxial part within the connection area. The first bevel gear 331 and the second motor 50 are fixed vertically in the mounting cavity 21. The output end of the second motor 50 passes through the mounting cavity 21 and is fixed with the second bevel gear 51. The second bevel gear 51 meshes with the first bevel gear 331. Thus, when the second motor 50 works, its output end drives the second bevel gear 51 to rotate and simultaneously drives the first bevel gear 331 to rotate. Since the first bevel gear 331 is fixed to the pivot shaft 33 and the pivot shaft 33 is fixed to the two second connecting parts 32, the entire lamp holder 30 rotates and swings around the vertical direction following the rotation of the first bevel gear 331, ultimately realizing the rotation and swing of the lamp holder 30 in the vertical direction.

[0053] The transmission direction between the first bevel gear 331 and the second bevel gear 51 is 90°.

[0054] In order to fix the second motor 50, a stepped slot 23 is provided near the bottom opening of the mounting cavity 21. The center of the slot 23 forms a through hole 231 for the output end of the second motor 50 to pass through. The slot 23 is also provided with a first wire hole (not shown in the figure) for the wire to pass through, so as to facilitate the wire of the control lamp bead 31 to pass through.

[0055] At the upper end of the lamp holder 30, a second wire hole 35 is provided between the two second connecting parts 32 for the wire to pass through. After the wire passes out along the mounting cavity 21, it passes through the second wire hole 35 again and enters the lamp holder 30 to connect to the lamp bead 31, thereby realizing the control of the lamp bead 31.

[0056] In the vertical swing position of the lamp holder 30, since the swing direction is generally a 180° range of rotation, the wire will not be kinked, so it can be directly connected by reserving the wire length and directly inserting it.

[0057] like Figure 7 As shown, it also includes a controller 60, which is installed and fixed in the installation area 11, for connecting an external power supply, controlling and powering the LED beads 31, the first motor 40 and the second motor 50;

[0058] Specifically, the controller 60 is connected to an external 220V power supply via wiring, and the corresponding drive circuit converts it into a 36V line for direct supply to the lamp bead 31 and a 6V line for supplying the first motor 40 and the second motor 50 respectively. In this embodiment, both the magnetic contact 70 and the magnetic contact 80 are columnar structures and their connection positions are located on their central axis.

[0059] Therefore, the line connection in this embodiment is as follows: Figure 7 As shown, the controller 60 is connected to the power supply module 61 to connect to an external power source. After conversion, the power source is directly connected to the first motor 40 in the installation area 11 via a wire (not shown in the figure). At the position of the horizontal rotation connection structure 90, the wire is connected to the magnetic contact 70. After the magnetic contact 70 is magnetically attracted by the magnetic contact 80, the power is transmitted to the wire connected to the magnetic contact 80. The wire continues to extend downward along the installation cavity 21 to connect to the second motor 50, and passes through the installation cavity 21 and into the lamp holder 30 to connect to the corresponding lamp bead 31.

[0060] In this embodiment, both the first motor 40 and the second motor 50 are micro motors or micro servo motors.

[0061] Preferred, such as Figure 7As shown, the remote control device 100 includes a remote control module 101 for inputting motor control instructions and a transmitting module 102 for transmitting the control instructions, the input end of the controller 60 is electrically connected to a receiving module 62 for receiving the control instructions, and the transmitting module 102 and the receiving module 62 are respectively an infrared transmitting module 102 and an infrared receiving module 62.

[0062] In this embodiment, the remote control device 100 can independently control the first motor 40 and the second motor 50, the remote control module 101 inputs corresponding control signals to control the forward and reverse rotation of the first motor 40 and the second motor 50, and the infrared transmitting module 102 transmits the control signals to the lamp, and the infrared receiving module 62 receives the signals and transmits them to the controller 60, and finally the corresponding control signals are transmitted to the first motor 40 and the second motor 50 through the controller 60 and the wires, to control the forward and reverse rotation of the first motor 40 and the second motor 50, thereby realizing the horizontal rotation and vertical rotation of the lamp, and finally adjusting the lighting position to meet the user's demand.

[0063] The beneficial effects of the present application are as follows:

[0064] The present application realizes the convenient adjustment of the lamp by controlling the horizontal rotation and vertical rotation of the lamp holder 30 through the first motor 40 and the second motor 50. In particular, the magnetic contact one 70 and the magnetic contact two 80 are used to realize the electrical connection at the rotation center position between the connecting rod 20 and the base 10, instead of the traditional direct connection of wires, so that the lamp holder 30 can freely rotate horizontally by 360°, without worrying about the problem of wire kinking or breaking, thereby ensuring the stability and safety of the lamp.

[0065] The present application has been described above in conjunction with the drawings, and obviously the specific implementation of the present application is not limited by the above manner, as long as various non-essential improvements are made by using the method concept and technical solution of the present application, or the concept and technical solution of the present application is directly applied to other occasions without improvement, all within the protection scope of the present application.
