[0042] Embodiment 1
[0043] Combination Figure 1 and Figure 2 The lamp body structure provided in the present application includes a fixing seat 100, a bracket 200, a driving mechanism 300, a light source wire 400 and a conductive slip ring 500, and the fixing seat 100 is installed with a power connector 110. The bracket 200 is rotatably installed on the fixing seat 100. The driving mechanism 300 is installed on the fixing seat 100 or the bracket 200, and the driving mechanism 300 is used to drive the bracket 200 to rotate relative to the fixing seat 100. The light source wire 400 is movably inserted into the bracket 200. The conductive slip ring 500 is installed on the fixing seat 100, one end of the conductive slip ring 500 is electrically connected to the power connector 110, and the other end of the conductive slip ring 500 is electrically connected to the light source wire 400.
[0044] The driving mechanism 300 drives the bracket 200 to rotate relative to the fixing seat 100 to achieve the control of the lighting angle. The light source wire 400 is movably arranged in the bracket 200 and will not rotate synchronously with the bracket 200. The conductive slip ring 500 is installed on the fixing seat 100. The conductive slip ring 500 obtains power from the power connector 110 on the fixing seat 100 and transmits it to the light source wire 400. Even if the light source wire 400 movably arranged in the bracket 200 is affected by the rotation of the bracket 200 and swings, since the conductive slip ring 500 can realize the power transmission between the two relatively rotating parts, the torsion of the light source wire 400 is weakened, and the light source wire can still be stably electrically connected and will not be entangled when it swings or rotates relative to the fixing seat 100, thereby improving the safety and reliability of the lamp body structure, achieving stable movement of the bracket 200 without the risk of winding, and preventing the light source wire 400 from twisting and failing.
[0045] In some embodiments, the conductive slip ring 500 includes a housing, a stator and a rotor. The housing is fixedly mounted on the fixing seat 100, the stator is insulated and mounted inside the housing, the stator is electrically connected to the power connector 110, the rotor is rotatably mounted in the stator, and the rotor and the stator are stably electrically connected, and the rotor is electrically connected to the light source wire 400. Based on this, the light source wire 400 is electrically connected to the power connector 110 through the conductive slip ring 500. The light source wire 400 can rotate or swing relative to the fixing seat 100, driving the rotor to rotate or swing relative to the stator. The end of the light source wire 400 has no fixed constraint, which reduces the torque caused by the rotation or swing.
[0046] In some embodiments, in combination Figure 2 The conductive slip ring 500 is electrically connected to the power connector 110 through a wire, and both ends of the wire are welded and fixed to the conductive slip ring 500 and the power connector 110, respectively, to ensure that the electrical connection between the wire and the conductive slip ring 500 and the power connector 110 is more firm, the electrical contact area is larger, and the stability and reliability of power transmission are guaranteed.
[0047] In some embodiments, in combination Figure 2 The bracket 200 has a through installation channel 210, the bracket 200 is rotatably installed on the fixing seat 100 around the installation channel 210, and the light source wire 400 is inserted into the installation channel 210. Based on this, the bracket 200 rotates around the installation channel 210, and the light source wire 400 is located at the rotation center, which can remain relatively still, avoiding the winding and twisting of the wire caused by the rotation, and at the same time reducing the wear caused by frequent rotation, thereby extending the service life of the light source wire 400.
[0048] It is understood that in other embodiments, the installation channel 210 may be an annular channel around the rotation center of the bracket 200. Similarly, the bracket 200 rotates, while the light source wire 400 located in the installation channel 210 is stationary relative to the rotation center, and the light source wire 400 will not be entangled or twisted. Of course, even if the light source wire 400 is driven by the bracket 200 to swing, since the conductive slip ring 500 can achieve a rotating electrical connection, the torsional force on the light source wire 400 can be reduced, thereby preventing the light source wire 400 from breaking and failing.
[0049] In one embodiment, in combination Figure 2 and Figure 3 The lamp body structure also includes a support sleeve 610, a first bearing 620 and a first bearing seat 630. The support sleeve 610 is installed on the fixing seat 100, and the support sleeve 610 extends into the installation channel 210. The first bearing seat 630 is installed on the bracket 200, and the first bearing 620 is arranged between the first bearing seat 630 and the support sleeve 610. Based on this, the bracket 200 is rotatably supported on the support sleeve 610 through the first bearing 620, and then stably supported on the fixing seat 100. The support sleeve 610 can support the bracket 200 360°, and at the same time can define the installation channel 210, so as to ensure that the conductive slip ring 500 or the light source wire 400 located in the installation channel 210 can work reliably, and reduce the wear of the conductive slip ring 500 or the light source wire 400 by other structures.
[0050] Specifically, combined Figure 3 The ends of the light source wire 400 and the conductive slip ring 500 extend into the support sleeve 610 and are electrically connected to each other. The support sleeve 610 ensures that the connection point between the light source wire 400 and the conductive slip ring 500 is not interfered by other structures, ensures the connection reliability between the two, and prevents power connection failure.
[0051] Specifically, the light source wire 400 is electrically connected to the conductive slip ring 500 via the torque center axis 420 . The torque center axis 420 can withstand greater torque than the light source wire 400 . Even if the torque center axis 420 is swung or rotated, the connection will not break or fail.
[0052] Specifically, the first bearing seat 630 is provided with a partition 631 which is spaced and surrounds the support sleeve 610, and the number of the first bearings 620 is two, and the two first bearings 620 are respectively against the two sides of the partition 631. The two first bearings 620 increase the support area between the bracket 200 and the fixing seat 100, improve the rotation stability of the bracket 200, and reduce the pressure on the single first bearing 620. The partition 631 limits the position of the first bearing 620 in the axial direction to prevent the first bearing 620 from shaking in the axial direction.
[0053] Optionally, combined Figure 2 and Figure 3 The upper and lower ends of the first bearing 620 located at the top respectively abut against the limit sleeve and the partition 631 to achieve its axial position stability, and its inner and outer sides respectively abut against the support sleeve 610 and the first bearing seat 630 to improve its radial position stability. The upper and lower ends of the first bearing 620 located at the bottom respectively abut against the partition 631 and the bottom flange of the support sleeve 610 to achieve its axial position stability, and its inner and outer sides respectively abut against the support sleeve 610 and the first bearing seat 630 to improve its radial position stability.
[0054] Specifically, combined Figure 3 The main body of the conductive slip ring 500 is located inside the fixing seat 100 and is protected by the fixing seat 100. One end of the conductive slip ring 500 extends out of the fixing seat 100 to connect with the light source wire 400. The support sleeve 610 and the conductive slip ring 500 are coaxially arranged so that the conductive slip ring 500 and the light source wire 400 are both located at the rotation center of the bracket 200 to remain stationary and weaken the torsion.
[0055] Optionally, the support sleeve 610 and the fixing seat 100 are installed on the inner and outer sides of the same plate of the fixing seat 100 to facilitate the coaxial arrangement of the two.
[0056] In some embodiments, in combination Figure 2 and Figure 4 The lamp body structure further includes a second bearing 640 and a second bearing seat 650. The second bearing seat 650 is mounted on the bracket 200. The second bearing seat 650 is located at one end of the mounting channel 210 away from the fixing seat 100. The second bearing 640 is disposed between the second bearing seat 650 and the light source wire 400. The second bearing 640 is conducive to stably supporting the light source wire 400, can share part of the load of the light source wire 400, reduces the load of the light source wire 400 on the first bearing 620, and helps to extend the service life of the first bearing 620.
[0057] In one embodiment, in combination Figure 2 and Figure 4The lamp body structure also includes a pressing plate 660, which is installed at one end of the second bearing seat 650 away from the fixing seat 100. The two ends of the second bearing 640 are respectively against the pressing plate 660 and the second bearing seat 650, so as to achieve the stability of the second bearing 640 in the axial direction, avoid the vibration of the second bearing 640 and the light source wire 400 caused by the rotation of the bracket 200, and help to ensure the stability of the light source wire 400. The light source wire 400 is movably arranged in the pressing plate 660.
[0058] In one embodiment, in combination Figure 2 and Figure 4 The lamp body structure further includes an elastic body 670, which is disposed between the second bearing 640 and the light source wire 400. The elastic body 670 can help reduce the impact of external vibration on the light source wire 400, thereby protecting the light source wire 400 from impact damage. The elastic body 670 can also reduce the noise caused by friction, thereby preventing the noise from interfering with the shooting effect.
[0059] Specifically, the elastic body 670 is fixedly connected to the light source wire 400, so as to better protect the light source wire 400, reduce unnecessary movement of the light source wire 400, and reduce the failure rate caused by looseness or poor pulling of the light source wire 400.
[0060] Specifically, one end of the elastomer 670 close to the pressure plate 660 is limited between the second bearing 640 and the pressure plate 660, thereby achieving axial position stability of the elastomer 670 and the light source wire 400. While protecting the light source wire 400 from friction and breakage, it also prevents the light source wire 400 from being pulled out by external force, thereby improving the reliability and stability of the connection of the light source wire 400.
[0061] Optionally, the elastic body 670 and the light source wire 400 are integrally formed, and the two are tightly fixed, not easy to loosen, and do not need to be assembled, thereby improving the position consistency of the two.
[0062] Optionally, the elastomer 670 is silicone.
[0063] In some embodiments, in combination Figure 1 and Figure 2 The light source wire 400 has a bent section 410, so that the light source wire 400 has a certain displacement elasticity on the rotation center line of the bracket 200, avoiding the connection between the light source wire 400 and the conductive slip ring 500 from being broken and failing due to pulling.
[0064] In one embodiment, in combination Figure 1 and Figure 2 The bending section 410 is located on a side of the bracket 200 away from the fixing base 100 , and has a larger space to avoid interference with the bracket 200 .
[0065] In one embodiment, the bending section 410 is elastically bent around the rotation axis of the bracket 200. With the help of the rebound property of the bending section 410 after bending, even if the light source wire 400 is pulled, it can be restored after the external force is removed, so that the light source wire 400 is always in a pulled state when the bracket 200 alternately pitches and tilts, and will not be entangled at the bottom of the moving bracket 200 to affect the use.
[0066] In one embodiment, in combination Figure 1 The bending section 410 is wound around the rotation center line of the bracket 200 into an arc shape or a spiral shape. The winding setting can make the space occupied by the bending section 410 smaller.
[0067] In some embodiments, in combination Figure 1 and Figure 2 The driving mechanism 300 includes a motor 310 and a reducer 320. The motor 310 is mounted on the bracket 200 or the reducer 320. The output shaft of the reducer 320 is rotatably connected to the fixed seat 100. For example, the motor 310 is mounted on the bracket 200, and the motor 310 drives the reducer 320 to output a rotation torque. The rotation torque acts on the fixed seat 100. The fixed seat 100 is fixedly arranged, so that the motor 310 and the reducer 320 rotate relative to the fixed seat 100, and then the bracket 200 rotates relative to the fixed seat 100.
[0068] Optionally, the light source wire 400 is movably passed through the reducer 320 to achieve compact assembly of the light source wire 400 and the reducer 320, and is also conducive to arranging the light source wire 400 on the axis of the output shaft of the reducer 320, so that it can be stationary and not subjected to torque.
[0069] Embodiment 2
[0070] The present application provides a lamp, comprising a light source and any one of the lamp body structures in the first embodiment, wherein the light source is mounted at one end of the light source wire 400 away from the fixing seat 100. The light source obtains electrical energy through the light source wire 400, the conductive slip ring 500 and the power connector 110 to emit light.
[0071] The driving mechanism 300 drives the bracket 200 to rotate relative to the fixing seat 100 to adjust the lighting angle, and the light source wire 400 is movably arranged in the bracket 200 and will not rotate synchronously with the bracket 200. Even if the light source wire 400 movably arranged in the bracket 200 is affected by the rotation of the bracket 200 and swings, since the conductive slip ring 500 can realize the power transmission between the two relatively rotating parts, the torsional force on the light source wire 400 is weakened, and the light source wire can still be stably electrically connected and will not be entangled when it swings or rotates relative to the fixing seat 100, so that the position stability of the light source and the light source wire 400 is high, the bracket 200 can be moved stably without the risk of winding, and the light source wire 400 can be prevented from twisting and failing.
[0072] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
