Abstract
Description
Technical Field
[0001] This invention relates to the field of intelligent lighting device technology, and more particularly to an intelligent building suspended lighting device. Background Technology
[0002] The core of intelligent buildings is the 5A system. Intelligent buildings organically integrate these five systems through a communication network system, combining structure, system, service, management, and their optimal combination to give buildings the characteristics of safety, convenience, efficiency, and energy saving.
[0003] Chinese invention patent CN116928639B discloses an intelligent adjustable building suspended lighting device, including a lighting body, a support base, an orientation control mechanism, an orientation adjustment and positioning auxiliary component, and a cleaning and protection control component. The device uses a suspended telescopic control rod to control the vertical height of the lighting body according to actual needs. When the illumination orientation needs adjustment, a first rotary control motor, in conjunction with the drive gear and transmission gear, achieves horizontal rotation. A second rotary control motor, in conjunction with the transmission shaft and lamp body connector, achieves vertical position adjustment. The orientation adjustment and positioning auxiliary component provides excellent assistance for orientation control and positioning, ensuring the stability of the illumination operation.
[0004] The aforementioned device, through its steering adjustment and positioning auxiliary components, supports the lamp body after the motor and drive shaft rotate, thereby extending its service life and ensuring the stability of the illumination work. However, due to gravity, the greater the upward rotation angle of the lamp body, the more support force is required to fix the lamp body in that position. The steering adjustment and positioning auxiliary mechanism in the prior art cannot adaptively adjust the friction force according to the upward rotation angle of the lamp body. When the lamp body needs to be fixed in a large angle position for a long time, it may not be able to achieve a stable fixing effect, which will not only damage the service life of the motor and drive shaft, but also affect the illumination work. Summary of the Invention
[0005] This application provides an intelligent building suspended lighting device that solves the problem in the prior art where, when the lamp body needs to be fixed at a large angle for a long time, the steering adjustment and positioning auxiliary component cannot adaptively adjust the friction locking force, thus failing to achieve a stable fixing effect, damaging the service life of the motor and drive shaft, and affecting the illumination work.
[0006] This application provides an intelligent suspended lighting device, including a lamp body, a support base, a suspension control telescopic rod, and a rotating part. The suspension control telescopic rod is fixedly installed on the support base, which also has a fixing hole for fixing to a wall. The rotating part is fixedly installed on the side of the suspension control telescopic rod away from the support base. The lamp body is installed at the bottom of the rotating part. The device also includes a control assembly, which includes a control shell, a fixing plate, a rotating disk, a friction ring, a mounting plate, a roller, and a mating bladder. The control shell is fixedly installed at the bottom of the rotating part. The fixing plate is fixedly installed at the top of the lamp body. The rotating disk is fixedly installed at the end of the fixing plate away from the lamp body and is rotatably installed inside the control shell. The friction ring is coaxially fixedly installed on one side of the rotating disk. The mounting plate is detachably installed on the control shell. The roller is rotatably installed on the side of the mounting plate facing the rotating disk. The longitudinal section of the roller is I-shaped, and the roller and the friction ring are in contact and mating with each other. There are two sets of mating bladders, which are fixed on the upper and lower sides of the roller facing the friction ring. The thickness of the friction ring increases gradually from the lamp body to the control shell.
[0007] Furthermore, each set of the cooperating capsules includes three auxiliary capsules, which are arranged in a ring array on the inner side of the roller, and each auxiliary capsule contains a medium layer filled with an inner medium, which is a colloid.
[0008] Furthermore, the dielectric layer is also filled with magnetic particles, and a metal sheet is fixedly installed on the friction ring. The metal sheet can generate magnetic attraction with the magnetic particles in the dielectric layer.
[0009] Furthermore, the width of the metal sheet increases progressively in the direction of increasing friction ring thickness.
[0010] Furthermore, the metal sheet is also equipped with several protrusions, which are not magnetic.
[0011] Furthermore, the density of the bumps decreases progressively as the width of the metal sheet increases.
[0012] Furthermore, a control motor is also installed on the control housing, and the main shaft of the control motor passes through the control housing and is coaxially and fixedly connected to the rotating disk.
[0013] Furthermore, the rotating part includes a rotating shell, a rotating motor, a driving gear, a driven gear, and a connecting rod. The rotating shell is fixedly connected to the output end of the suspension control telescopic rod. An installation groove is provided inside the rotating shell. The driving gear and the driven gear are both rotatably installed in the installation groove. One end of the connecting rod passes through the rotating shell and is fixedly connected to the driven gear coaxially. The other end of the connecting rod is fixedly connected to the control shell. The rotating motor is mounted on the rotating shell. The main shaft of the rotating motor passes through the rotating shell and is fixedly connected to the driving gear coaxially. The driving gear and the driven gear mesh.
[0014] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages:
[0015] Firstly, this application improves the thickness of the friction ring by progressively increasing it, and in conjunction with the roller and the mating bladder, it not only improves the single-sided contact in the prior art to a double-sloping-face contact, increasing the contact area and friction, but also provides higher normal extrusion force and tangential frictional resistance under the same pressure. Furthermore, when the lamp body rotates at a large angle, the thickness of the friction ring in contact with the roller also increases, and the extrusion force of the friction ring on the mating bladder also increases, resulting in greater friction to maintain the stability of the lamp body in that position. Moreover, the contact stress distribution is more uniform, and long-term high-pressure extrusion can be avoided through pressure adjustment, reducing the wear of the friction ring and roller. For lamp bodies of different specifications, only the internal pressure of the mating bladder needs to be adjusted to match the optimal positioning force, without the need to replace mechanical parts.
[0016] Secondly, this application uses three auxiliary bags to form each set of mating bags, so that the friction between the roller and the friction ring gradually increases with rotation. As the thickness of the friction ring in contact with the roller gradually increases, the transition between the two is more stable. In addition, the colloid filled in the medium layer makes the deformation of the auxiliary bags more stable, and the fit with the friction ring is higher when under pressure. Moreover, the failure of a single auxiliary bag will not affect the overall function of the device, making the lamp body more stable after rotation.
[0017] Thirdly, this application uses magnetic particles and gradually wide metal sheets to make the larger the angle of rotation of the lamp body, the stronger the magnetic attraction, perfectly matching the gravitational torque requirements; and the combination of mechanical friction and magnetic attraction increases the total holding force, reduces the dependence on the friction ring for compression, and improves its service life; the friction ring and roller bearing are subjected to less stress, while the magnetic attraction provides a fail-safe backup to prevent the lamp body from falling suddenly.
[0018] Fourth, this application, through the setting of protrusions, allows the contact between the auxiliary bag and the protrusions to generate a certain vibration force when the friction ring rotates with the rotating disk. This makes the distribution of magnetic particles in the dielectric layer more uniform, keeping the magnetic particles in an easily magnetized state at all times. Once a large-angle positioning is required, the magnetic attraction force can instantly reach the design value, ensuring the stability of the lamp body at large angles. Furthermore, through the density design of the protrusions, when the lamp body rotates at a small angle, the density of the protrusions at that position is high, reducing the contact area between the auxiliary bag and the metal sheet. In this state, the lamp body can be stabilized by the squeezing friction between the auxiliary bag and the friction ring. As the rotation angle of the lamp body increases, the density of the protrusions gradually decreases, and the contact area between the auxiliary bag and the metal sheet gradually increases to adapt to the greater fixing force required when the lamp body is at a large angle, thus ensuring the stability of the lamp body.

[0031] Example 1
[0032] like Figures 1-4As shown in the figure, this application provides an intelligent suspended lighting device, including a lamp body 100, a support base 110, a suspension control telescopic rod 120, and a rotating part 130. The suspension control telescopic rod 120 is fixedly installed on the support base 110 and is used to adjust the height of the lamp body 100. This is prior art and will not be described in detail. The support base 110 also has fixing holes for fixing to the wall. The device is fixed by bolts engaging with the fixing holes. The rotating part 130 is fixedly installed on the side of the suspension control telescopic rod 120 away from the support base 110. The lamp body... The lamp body 100 is installed at the bottom of the rotating part 130 and also includes a control assembly 200. The control assembly 200 includes a control housing 210, a fixing plate 212, a rotating disk 213, a friction ring 220, a mounting plate 230, a roller 240, and a mating bag 250. The control housing 210 is fixedly installed at the bottom of the rotating part 130, the fixing plate 212 is fixedly installed at the top of the lamp body 100, the rotating disk 213 is fixedly installed at the end of the fixing plate 212 away from the lamp body 100, the rotating disk 213 is rotatably installed inside the control housing 210, and the friction ring 220 is coaxially fixedly installed on the rotating disk 210. On one side of the control housing 210, the mounting plate 230 is detachably mounted on the mounting plate 230 facing the rotating disk 213. The roller 240 has an I-shaped longitudinal section and is in contact with the friction ring 220. There are two sets of mating pouches 250, which are fixed on the upper and lower sides of the roller 240 facing the friction ring 220. The thickness of the friction ring 220 increases gradually from the lamp body 100 to the control housing 210. When the lamp body 100 is rotated upward to adjust the angle, the roller 240 is constantly engaged by friction through the groove on it. On the friction ring 220, the two sets of mating pouches 250 also constantly squeeze the friction ring 220. Compared with the prior art, the single-sided contact has been improved to double-sloping contact, which increases the contact area and improves the friction force. Under the same pressure, it can provide higher normal extrusion force and tangential friction resistance. When the lamp body 100 rotates at a large angle, the deflection torque of the lamp body 100 under gravity increases. At this time, the thickness of the friction ring 220 contacted by the roller 240 also increases. At this time, the extrusion force of the friction ring 220 on the mating pouches 250 also increases, obtaining greater friction force to maintain the stability of the lamp body 100 at this position.
[0033] Preferably, a control motor 211 is also installed on the control housing 210. The main shaft of the control motor 211 passes through the control housing 210 and is coaxially and fixedly connected to the rotating disk 213. The operation of the control motor 211 can drive the rotating disk 213 to rotate, thereby realizing the rotation of the lamp body 100. The control motor 211 is a servo motor, which can lock the position of the lamp body 100 after rotation. This is the prior art, so it will not be described in detail.
[0034] Preferably, the rotating part 130 includes a rotating shell 131, a rotating motor 132, a driving gear 133, a driven gear 134, and a connecting rod 135. The rotating shell 131 is fixedly connected to the output end of the suspension control telescopic rod 120. An installation groove is provided inside the rotating shell 131. The driving gear 133 and the driven gear 134 are rotatably installed in the installation groove. One end of the connecting rod 135 passes through the rotating shell 131 and is coaxially fixedly connected to the driven gear 134. The other end of the connecting rod 135 is fixedly connected to the control shell 210. The rotating motor 132 is installed on the rotating shell 131. The main shaft of the rotating motor 132 passes through the rotating shell 131 and is coaxially fixedly connected to the driving gear 133. The driving gear 133 meshes with the driven gear 134. When the rotating motor 132 is working, it can drive the driven gear 134, which meshes with it, to rotate through the driving gear 133, thereby realizing the rotation of the lamp body 100. This is the prior art and will not be described in detail.
[0035] The technical solutions described in the embodiments of this application have at least the following technical effects or advantages:
[0036] By progressively increasing the thickness of the friction ring 220 and cooperating with the roller 240 and the mating bladder 250, the single-sided contact in the prior art is improved to a double-sloping-face contact, increasing the contact area and friction. Under the same pressure, it can provide higher normal extrusion force and tangential friction resistance. When the lamp body 100 rotates at a large angle, the thickness of the friction ring 220 in contact with the roller 240 also increases, and the extrusion force of the friction ring 220 on the mating bladder 250 also increases, resulting in greater friction to maintain the stability of the lamp body 100 in that position. Furthermore, the contact stress distribution is more uniform, and long-term high-pressure extrusion can be avoided through pressure adjustment, reducing the wear of the friction ring 220 and the roller 240. For lamp bodies 100 of different specifications, only the internal pressure of the mating bladder 250 needs to be adjusted to match the optimal positioning force, without the need to replace mechanical parts.
[0037] Example 2
[0038] like Figure 5 As shown, preferably, each set of the plenum 250 includes three auxiliary plenums 251, which are arranged in a ring array on the inner side of the roller 240. Each auxiliary plenum 251 contains a medium layer 252, which is filled with an inner medium, which is a colloid. The internal pressure of the three auxiliary plenums 251 increases progressively.
[0039] The technical solutions described in the embodiments of this application have at least the following technical effects or advantages:
[0040] Each set of mating bladders 250 consists of three auxiliary bladders 251, which makes the friction between the roller 240 and the friction ring 220 gradually increase with rotation. As the thickness of the friction ring 220 in contact with the roller 240 gradually increases, the transition between the two is smoother. Furthermore, the colloid filled in the medium layer 252 makes the deformation of the auxiliary bladders 251 more stable, and the fit with the friction ring 220 is higher when under pressure. Moreover, the failure of a single auxiliary bladder 251 will not affect the overall function of the device, making the lamp body 100 more stable after rotation.
[0041] Example 3: To further improve the stability of fixing the position of the lamp body 100 after it has undergone a large-angle rotation, such as... Figures 6-7 As shown, further improvements are made to Example 2:
[0042] Preferably, the dielectric layer 252 is further filled with magnetic particles, and a metal sheet 221 is fixedly installed on the friction ring 220. The metal sheet 221 can generate magnetic attraction with the magnetic particles in the dielectric layer 252.
[0043] Preferably, the width of the metal sheet 221 increases gradually in the direction of increasing thickness of the friction ring 220.
[0044] The technical solutions described in the embodiments of this application have at least the following technical effects or advantages:
[0045] By filling the magnetic particles and using the gradually wide metal sheet 221, the larger the rotation angle of the lamp body 100, the stronger the magnetic attraction, perfectly matching the gravitational torque requirements. Furthermore, the combination of mechanical friction and magnetic attraction increases the total holding force, reduces the reliance on the friction ring 220 for compression, and improves its service life. The friction ring 220 and roller 240 bear less stress, while the magnetic attraction provides a safety backup in case of failure, preventing the lamp body 100 from suddenly falling.
[0046] In Example 4, the magnetic particles used in Example 3, combined with the metal sheet 221, were used to enhance the fixation effect on the lamp body 100 after large-angle movement. However, the applicant found that when the device was not used for a long time, the magnetic particles tended to settle and accumulate at the bottom of the auxiliary bag 251; they could not be attracted and cooperate with the metal sheet 221 in time when used again; and when the lamp body 100 was fixed at certain small-angle positions for a long time and the angle of the lamp body 100 needed to be adjusted again, the magnetic attraction between the magnetic particles and the metal sheet 221 would affect the control motor 211 driving the lamp body 100 to rotate. To solve the above problems, such as Figure 8 As shown, there are further improvements to Embodiment 3:
[0047] Preferably, the metal sheet 221 is further provided with a plurality of protrusions 222, which are non-magnetic.
[0048] Preferably, the density of the bump 222 decreases gradually in the direction of increasing width of the metal sheet 221.
[0049] The technical solutions described in the embodiments of this application have at least the following technical effects or advantages:
[0050] By setting the protrusion 222, when the friction ring 220 rotates with the rotating disk 213, the contact between the auxiliary bag 251 and the protrusion 222 can generate a certain vibration force, making the magnetic particles more evenly distributed in the dielectric layer 252, keeping the magnetic particles in an easily magnetized state at all times. Once a large-angle positioning is required, the magnetic attraction force can instantly reach the design value, ensuring the stability of the lamp body 100 at a large angle. Furthermore, through the density design of the protrusion 222, when the lamp body 100 rotates at a small angle, the density of the protrusion 222 at that position is high, reducing the contact area between the auxiliary bag 251 and the metal sheet 221. In this state, the compression friction between the auxiliary bag 251 and the friction ring 220 can achieve the stability of the lamp body 100. As the rotation angle of the lamp body 100 increases, the density of the protrusion 222 gradually decreases, and the contact area between the auxiliary bag 251 and the metal sheet 221 gradually increases to adapt to the greater fixing force required when the lamp body 100 is at a large angle, so as to ensure the stability of the lamp body 100.
[0051] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. For those skilled in the art, the present invention can have various modifications and variations. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
