[0002] A chandelier is a lamp hung on the ceiling. In some occasions, multiple chandeliers are combined into patterns to obtain different lighting positions or visual effects. However, when multiple chandeliers are currently installed, each chandelier needs to be installed by drilling a hole in the wall separately, which has the problems of complex installation, low efficiency and high cost. Summary of the invention

[0003] The main purpose of the present invention is to provide a combined DIY spliced ​​lamp, aiming to solve the technical problems of complex installation, low efficiency and high cost when multiple chandeliers are installed in combination in the prior art.

[0004] To achieve the above-mentioned purpose, the present invention proposes a combined DIY splicing lamp, comprising a main hanging member, a cross hanging assembly and multiple lamp modules, the main hanging member is used to be installed and fixed to the ceiling of an external device, the cross hanging assembly comprises multiple cross hanging members connected in sequence end to end laterally, two adjacent cross hanging members are rotatably connected, the main hanging member is fixedly connected to one of the cross hanging members, the lamp module comprises a lamp body, one lamp module is correspondingly matched with one cross hanging member, the lamp body is arranged on the lower side of the cross hanging member, the lamp body and the corresponding cross hanging member are relatively fixed in the up and down directions, the lamp body and the corresponding cross hanging member are circumferentially fixed, and when two adjacent cross hanging members rotate relative to each other, the two adjacent lamp bodies can rotate relative to each other to change the relative positions of the two adjacent lamp modules.

[0005] This combined DIY spliced ​​lamp is installed and fixed to the ceiling through a main hanger. The main hanger is connected to a horizontal hanger in the horizontal hanging assembly, and multiple lamp modules are connected to multiple horizontal hangers in the horizontal hanging assembly. In this way, multiple lamp modules are connected to the horizontal hanging assembly and then connected to the ceiling through the main hanger. In this way, it is only necessary to install and fix the main hanger on the ceiling, and there is no need to install each lamp module on the ceiling separately, which can simplify the installation, improve the installation efficiency and reduce the cost. In addition, since two adjacent horizontal hangers can be rotated, the positions of two adjacent lamp modules can be changed. The positions of multiple lamp modules are changed and spliced ​​to form different combined shape patterns, which can enrich the shape of the lamp.

[0006] Preferably, the lamp module also includes a plurality of magnet groups, and the plurality of magnet groups are circumferentially arranged on the outside of the lamp body. One of the magnet groups in one of the lamp modules is matched with one of the magnet groups in another adjacent lamp module and can attract each other magnetically. When the relative positions of the two adjacent lamp modules change, the corresponding two magnet groups change.

[0007] An attractive force can be generated between two adjacent lamp modules through corresponding magnet groups, so that the two lamp modules fit together or reduce the gap, and maintain the relative position between the two lamp modules; since multiple magnet groups are arranged on the periphery of each lamp module, when the positions of the two lamp modules change, the magnet groups that attract the two lamp modules change to adapt to the change in the positions of the two lamp modules so that they can still attract each other.

[0008] Preferably, two adjacent horizontal hangers are arranged up and down, and are rotatably connected to each other via a first hinge column. A first hanger is fixedly connected to the lamp body, and the upper side of the first hanger is fixedly connected to the corresponding horizontal hanger.

[0009] The first hinged column connects the two horizontal hanging members so that the horizontal hanging members can rotate relative to each other; the horizontal hanging members are fixed to the lamp body through the first hanging member.

[0010] Preferably, a leveling through hole is provided on the horizontal hanging member, a leveling screw is passed through the leveling through hole, a leveling nut is threadedly connected to the leveling screw, the horizontal hanging member abuts against the leveling nut, a leveling screw hole is provided on the lamp body, and the lower end of the leveling screw is threadedly connected to the corresponding leveling screw hole of the adjacent lamp body.

[0011] By rotating the leveling screw and the leveling nut, the distance between the corresponding lamp body and the horizontal hanging piece can be adjusted, and the horizontality of the lamp body can be adjusted to make multiple lamp modules more neat after splicing.

[0012] Preferably, the two adjacent horizontal hanging members are respectively the first horizontal member and the second horizontal member, the first horizontal member is fixedly connected with a rotation drive motor, the rotation drive motor is transmission-connected with the second horizontal member, and the rotation drive motor can drive the second horizontal member and the lamp module corresponding to the second horizontal member to rotate horizontally.

[0013] The rotary drive motor is arranged on one of the two adjacent horizontal hangers, and the rotary drive motor can drive the other horizontal hanger to rotate, so that the two adjacent horizontal hangers and the lamp module can automatically change their positions.

[0014] Preferably, a first gear is fixedly connected to the rotating shaft of the rotary drive motor, a second gear is provided on the second cross member, the second cross member is circumferentially fixed to the second gear, and the first gear is meshed with the second gear.

[0015] Preferably, the lamp body is a prism, and a first slide groove is provided on a side of the first cross member close to the second cross member, and the first slide groove extends along the extension direction of the first cross member. A second hinge column is fixed on the second gear, and the second gear is fixedly connected to the second cross member through the second hinge column. The second hinge column is slidably connected to the first slide groove, and the second hinge column can rotate in the first slide groove. The center distance between two adjacent lamp bodies when they are close to each other is the first distance, and the center distance between two adjacent lamp bodies when they are far away from each other is the second distance. The difference between the second distance and the first distance is less than the tooth height of the second gear.

[0016] When the lamp bodies of the prismatic body are close to each other, they are close to each other laterally, and at this time, the center distance between the two lamp bodies is the first distance; in the process of rotating to change the position, the two lamp bodies interfere with each other when they rotate to the angular parts and abut against each other, and the center distance between the two lamp bodies will be enlarged, that is, reaching the second distance, so a first sliding groove is provided on the first cross member for sliding the second hinged column of the second gear, so that the second cross member can slide away from the first cross member; at the same time, in order to enable the two cross hanging members to maintain drive when changing between the first distance and the second distance, that is, to keep the first gear and the second gear engaged, the difference between the second distance and the first distance is set to be smaller than the tooth height of the second gear, so that during the rotation of the lamp body, the first gear and the second gear can be kept engaged to transmit power while the distance is pulled apart, thereby completing the position change between the two lamp modules; when passing the position where the angular parts abut against each other, under the attraction of the magnet group, the two lamp modules gradually approach each other while rotating relative to each other, and the first gear and the second gear approach each other.

[0017] Preferably, a buffer elastic member is provided on the outer circumferential surface of the lamp body, and the buffer elastic member is used to contact the outer circumferential surface of the adjacent lamp body.

[0018] The buffer elastic member contacts the outer circumferential surface of the adjacent lamp body, and can absorb some interference and collision forces during rotation, help the rotation to be smoother, and reduce the noise of friction and collision between the lamp bodies during rotation.

[0020] The power supply between two adjacent lamp modules is achieved through the power connection component. Only one of the multiple lamp modules needs to be powered on to achieve the power supply of multiple lamp modules. There is no need to wire and power each lamp module separately, which can simplify the installation and improve the installation efficiency. Moreover, the position change between the lamp modules will not be affected by the wiring.

[0021] Preferably, the power connection component includes an electrically connected wire, a spring and a top bead, the wire and the top bead are respectively arranged at both ends of the spring, the wires of multiple power connection components in one lamp module are electrically connected, the lamp body is provided with a power connection hole, the spring is arranged in the power connection hole, the wire is arranged on the inner side of the lamp body, the top bead can elastically protrude or retract into the power connection hole with the help of the spring, and the corresponding two power connection components of two adjacent lamp modules are abutted with each other by the help of the two top beads to achieve electrical connection.

[0022] The wire inside the lamp body can be energized to make the spring and the top bead charged. Under normal circumstances, the top bead protrudes from the power connection hole. When the power connection components corresponding to the two adjacent lamp modules are turned on, the corresponding top beads on both sides remain in contact under the action of the spring, thereby facilitating the power supply between the two lamp modules.

[0043] like Figures 1 to 14 As shown, a combined DIY spliced ​​lamp includes a main hanging component 1, a horizontal hanging component and a plurality of lamp modules 3.

[0044] The upper end of the main hanger 1 is used to be installed and fixed to the ceiling, and the lower end of the main hanger 1 is connected to the cross-hanging assembly. The cross-hanging assembly includes multiple cross-hanging members 2 connected in sequence end to end, and two adjacent cross-hanging members 2 are rotatably connected. The lower end of the main hanger 1 is fixedly connected to one of the multiple cross-hanging members 2.

[0045] The lamp module 3 includes a lamp body 31, a light source board is provided on the inner side of the lamp body 31, and a light-transmitting board is provided on the lower side of the lamp body 31. The light source board emits light that irradiates downward through the light-transmitting board. One lamp module 3 is matched with one cross-hanging member 2. The lamp body 31 is provided on the lower side of the cross-hanging member 2. The lamp body 31 and the corresponding cross-hanging member 2 are relatively fixed in the up and down directions. The lamp body 31 and the corresponding cross-hanging member 2 are circumferentially fixed. When two adjacent cross-hanging members 2 rotate relative to each other, the two adjacent lamp bodies 31 can rotate relative to each other to change the relative positions of the two adjacent lamp modules 3.

[0046] This combined DIY spliced ​​lamp is installed and fixed to the ceiling through a main hanger 1, and the main hanger 1 is connected to a horizontal hanger 2 in the horizontal hanging assembly, and multiple lamp modules 3 are connected to multiple horizontal hangers 2 in the horizontal hanging assembly. In this way, multiple lamp modules 3 are connected to the horizontal hanging assembly and then connected to the ceiling through the main hanger 1. In this way, it is only necessary to install and fix the main hanger 1 on the ceiling, and there is no need to install each lamp module 3 on the ceiling separately, which can simplify the installation, improve the installation efficiency and reduce the cost. In addition, since two adjacent horizontal hangers 2 can be rotated, the positions of two adjacent lamp modules 3 can be changed. After a lamp module 3 rotates and changes its position, the other lamp modules 3 fixed thereto also follow the swing and change their positions. The position changes of multiple lamp modules 3 are spliced ​​to form different combined shape patterns, which can enrich the shape of the lamp.

[0047] In some specific embodiments, the main hanging member 1 is a vertical hanging rod arranged vertically, and the horizontal hanging member 2 is a horizontal hanging rod extending laterally. The main hanging member 1 can be connected to the horizontal hanging member 2 located at the head end, and can also be connected to the horizontal hanging member 2 located in the middle.

[0048] In some specific embodiments, the lamp module 3 also includes multiple magnet groups 32, which are circumferentially arranged on the outside of the lamp body 31. A magnet group 32 in one lamp module 3 is matched with a magnet group 32 in another adjacent lamp module 3 and can be magnetically attracted to each other. When the relative positions of two adjacent lamp modules 3 change, the corresponding two magnet groups 32 change.

[0049] The two adjacent lamp modules 3 can generate attraction through the corresponding magnet groups 32, so that the two lamp modules 3 fit together or reduce the gap, and maintain the relative position between the two lamp modules 3; because multiple magnet groups 32 are arranged on the periphery of each lamp module 3, when the positions of the two lamp modules 3 change, the magnet groups 32 that attract the two lamp modules 3 change to adapt to the change of the positions of the two lamp modules 3. Specifically, one magnet can be arranged in one magnet group 32, or more than two magnets can be arranged on the side of the lamp body 31 to improve stability.

[0050] In some specific embodiments, the lamp module 3 also includes multiple power connection components 34, which are arranged circumferentially on the outside of the lamp body 31, and multiple magnet groups 32 are arranged one by one on the sides of the multiple power connection components 34. All power connection components 34 in a lamp module 3 are electrically connected, and a power connection component 34 in a lamp module 3 is matched with a power connection component 34 in another adjacent lamp module 3 and can be electrically connected. When the relative positions of two adjacent lamp modules 3 change, the corresponding two power connection components 34 change.

[0051] The current installation of multiple chandeliers requires each chandeliers to be individually wired and powered, which is troublesome and inefficient. In this embodiment, two adjacent lamp modules 3 are powered through a power connection component 34. Only one of the multiple lamp modules 3 needs to be powered on to power all the lamp modules 3. Preferably, the power cord is connected to the power connection component 34 of the lamp module 3 close to the main hanging part 1. Each lamp module 3 does not need to be individually wired and powered, which can simplify the installation and improve the installation efficiency. Moreover, the position change between the lamp modules 3 is not affected by the wiring. When each magnet group 32 has two magnets, the power connection component 34 can be set between the two magnets to improve stability.

[0052] Further, refer to Figure 4 The power connection component 34 includes an electrically connected wire 341, a spring 342 and a top bead 343. The wire 341 and the top bead 343 are respectively arranged at the two ends of the spring 342. The wires 341 of multiple power connection components 34 in a lamp module 3 are electrically connected. A power connection hole is provided on the lamp body 31. The spring 342 is arranged in the power connection hole. The wire 341 is arranged on the inner side of the lamp body 31. The top bead 343 can elastically protrude or retract into the power connection hole with the help of the spring 342. The corresponding two power connection components 34 of two adjacent lamp modules 3 are electrically connected by abutting with the help of two top beads 343.

[0053] The wire 341 inside the lamp body 31 can be energized to charge the spring 342 and the top bead 343. Under normal conditions, the top bead 343 protrudes from the power connection hole. When the power connection components 34 corresponding to two adjacent lamp modules 3 are turned on, the corresponding top beads 343 on both sides are kept in contact under the action of the spring 342, so as to facilitate the power connection between the two lamp modules 3. A wire 341, a spring 342 and a top bead 343 form a group. The power connection component 34 is provided with at least two wires 341, two springs 342 and two top beads 343 to form at least two groups, and the two groups correspond to the live wire and the neutral wire respectively.

[0054] The position change adjustment structure of two adjacent horizontal hanging members 2 and two adjacent lamp modules 3 in the horizontal hanging assembly can adopt a manual adjustment structure or an electric adjustment structure, which can be referred to the following embodiments respectively.

[0055] Embodiment 1:

[0056] Reference Figures 1 to 3 The manual adjustment structure can refer to the first embodiment. The two adjacent horizontal hangers 2 are arranged up and down. The two adjacent horizontal hangers 2 are rotatably connected through the first hinge column 21. The first hanger 41 is fixedly connected to the lamp body 31, and the upper side of the first hanger 41 is fixedly connected to the corresponding horizontal hanger 2.

[0057] The first hinged column 21 connects the two cross hangers 2 so that the cross hangers 2 can rotate relative to each other, and the multiple cross hangers 2 are supported by multiple first hinged columns 21; the cross hangers 2 are fixed to the lamp body 31 through the first hangers 41. When manually adjusting the splicing, the first hangers 41 can be loosened first to adjust the positions of the two lamp modules 3, and then the cross hangers 2 are rotated to adapt to the positions of the two lamp modules 3, and then the first hangers 41 are fixed to the lamp body 31. At the same time, the magnet group 32 can attract the two lamp bodies 31 to keep them close and fixed, and the position adjustment and installation splicing of the two lamp modules 3 can be completed.

[0058] Furthermore, a horizontal hanger 2 passes through two lamp bodies 31, and a second hanger 42 is provided on the upper side of the lamp body 31. The second hanger 42 on the front lamp body 31 and the first hanger 41 on the rear lamp body 31 are close to and connected to the same horizontal hanger 2, so that the two lamp modules 3 maintain relative positions.

[0059] Furthermore, a leveling through hole is provided on the horizontal hanging member 2, a leveling screw 51 is passed through the leveling through hole, a leveling nut 52 is threadedly connected to the leveling screw 51, the horizontal hanging member 2 abuts against the leveling nut 52, a leveling screw hole 311 is provided on the lamp body 31, and the lower end of the leveling screw 51 is threadedly connected to the corresponding leveling screw hole 311 of the adjacent lamp body 31.

[0060] Rotating the leveling screw 51 and the leveling nut 52 can adjust the distance between the corresponding lamp body 31 and the horizontal hanging member 2, adjust the level of the lamp body 31, and make the multiple lamp modules 3 more neat after splicing. Furthermore, a level 35 that can indicate the horizontal state of the lamp body 31 is provided on the lamp body 31, which is convenient for the installer to observe when adjusting the level.

[0061] In the electric adjustment structure, two adjacent horizontal hanging members 2 are respectively the first horizontal member 23 and the second horizontal member 24. A rotary drive motor 6 is fixedly connected to the first horizontal member 23. The rotary drive motor 6 is transmission-connected to the second horizontal member 24. The rotary drive motor 6 can drive the second horizontal member 24 and the lamp module 3 corresponding to the second horizontal member 24 to rotate horizontally.

[0062] The rotary drive motor 6 is disposed on one of the two adjacent horizontal hangers 2, and the rotary drive motor 6 can drive the other horizontal hanger 2 to rotate, so that the two adjacent horizontal hangers 2 and the lamp module 3 can automatically change their positions. The upper side of the lamp body 31 is fixedly connected with a third hanger 443, and the upper side of the third hanger 443 is fixedly connected to the horizontal hanger 2.

[0063] A first gear 61 is fixedly connected to the rotating shaft of the rotary drive motor 6, a second gear 62 is provided on the second cross member 24, and the second cross member 24 is circumferentially connected to the second gear 62, and the first gear 61 is meshed with the second gear 62. Two adjacent cross suspension members 2 are rotated in phase through the meshing transmission of the first gear 61 and the second gear 62. The rotary drive motor 6 can also use other transmission structures to drive the second cross member 24 to rotate.

[0064] When the transmission structure of the first gear 61 and the second gear 62 is adopted, when the lamp body 31 is cylindrical, or the center distance between the two lamp bodies 31 remains unchanged when the two lamp bodies 31 rotate relative to each other, the second gear 62 can be fixedly connected to the second cross member 24 .

[0065] When the lamp body 31 is a prism such as a hexagon, the sides of the two lamp bodies 31 are required to be close to each other, and the gap between the two lamp bodies 31 is required to be small. Since the distance from the corner of the prism to the center is greater than the distance from the side to the center, the distance between the two lamp bodies 31 will change during the rotation process. It is necessary to keep the first gear 61 and the second gear 62 engaged to transmit power during the rotation of the second cross member 24. The arrangement of the first cross member 23, the second cross member 24, the first gear 61 and the second gear 62 can refer to the following embodiments:

[0066] Embodiment 2:

[0067] Reference Figures 5 to 14 A first slide groove 25 is provided on one side of the first cross member 23 close to the second cross member 24. The first slide groove 25 extends along the extension direction of the first cross member 23. A second hinge column 621 is fixed on the second gear 62. The second gear 62 is fixedly connected to the second cross member 24 through the second hinge column 621. The second hinge column 621 is slidably connected in the first slide groove 25. The second hinge column 621 can rotate in the first slide groove 25. The center distance between two adjacent lamp bodies 31 when they are close to each other is the first distance, and the center distance between two adjacent lamp bodies 31 when they are far away from each other is the second distance. The difference between the second distance and the first distance is less than the tooth height of the first gear 61 and the second gear 62. Preferably, the end of the first slide groove 25 away from the first gear 61 can limit the second hinge column 621 from moving away from the outside, so that the first gear 61 and the second gear 62 are separated.

[0068] When the prismatic lamp bodies 31 are close to each other, the sides are close to each other. Figure 7 and Figure 8 , at this time, the center distance between the two lamp bodies 31 is the first distance; in the process of rotating and changing the position, the two lamp bodies 31 interfere when they are rotated to the corners and abut against each other, refer to Figures 9 to 12, the center distance between the two lamp bodies 31 will be enlarged, that is, it reaches the second distance, so a first slide groove 25 for the second hinge column 621 of the second gear 62 to slide is provided on the first cross member 23, so that the second cross member 24 can slide away from the first cross member 23; at the same time, in order to keep the two cross hanging members 2 driven when changing from the first distance to the second distance, that is, to keep the first gear 61 and the second gear 62 meshing, the difference between the second distance and the first distance is set to be smaller than the tooth height of the second gear 62, so that during the rotation of the lamp body 31, the first gear 61 and the second gear 62 can be kept meshing and transmitting power while the distance is pulled apart, thereby completing the position change between the two lamp modules 3; when passing the position where the angular parts are in contact, under the attraction of the magnet group 32, the two lamp modules 3 gradually approach each other while rotating relative to each other, referring to Fig.13 and Fig.14 , the first gear 61 and the second gear 62 are close to each other.

[0069] Embodiment three:

[0070] The second gear 62 is rotatably connected to the first cross piece 23, and a second slide groove is provided on the second cross piece 24. The second slide groove extends along the extension direction of the second cross piece 24. A third hinge column is fixed on the second gear 62, and the third hinge column is arranged in the second slide groove and can slide. The third hinge column and the second slide groove are circumferentially fixed and cannot rotate relative to each other, so that the second gear 62 maintains a center distance unchanged with the first gear 61. When the second gear 62 rotates, the second cross piece 24 can be driven to rotate. When it is at the angular position, the second cross piece 24 moves outward under the action of the second slide groove. At the same time, the second gear 62 slides in the second slide groove and can keep driving the second cross piece 24 to rotate. When passing the position where the angular position abuts, under the attraction of the magnet group 32, the two lamp modules 3 gradually approach each other while rotating relative to each other.

[0071] Furthermore, a buffer elastic member 33 is disposed on the outer circumference of the lamp body 31 , and the buffer elastic member 33 is used to contact the outer circumference of an adjacent lamp body 31 .

[0072] The buffer elastic member 33 contacts the outer peripheral surface of the adjacent lamp body 31, and can absorb some interference and collision force during rotation, help the rotation to be smoother, and reduce the noise of friction and collision between the lamp bodies 31 during rotation. The buffer elastic member 33 can be made of EVA cotton or rubber, and the EVA cotton can have a Shore A hardness of 65-78 degrees.

[0073] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
