Technical Field

[0001] This application relates to the field of electronic device accessories technology, and in particular to a rotating device and a ceiling-mounted bracket. Background Technology

[0002] Ceiling-mounted brackets are a type of bracket used to suspend electronic devices such as televisions with displays and cables from the ceiling.

[0035] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

[0036] In the description of this application, it should be understood that the orientation descriptions, such as up, down, front, back, left, right, etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0037] In the description of this application, "several" means one or more, "multiple" means two or more, "greater than," "less than," and "exceeding" are understood to exclude the stated number, while "above," "below," and "within" are understood to include the stated number. The use of "first" and "second" in the description is merely for distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the number of indicated technical features, or implicitly indicating the order of the indicated technical features.

[0038] In the description of this application, unless otherwise expressly defined, terms such as "setup," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this application in conjunction with the specific content of the technical solution.

[0039] In the description of this application, the terms "one embodiment," "some embodiments," "illustrative embodiment," "example," "specific example," or "some examples," etc., refer to specific features, structures, materials, or characteristics described in connection with that embodiment or example, which are included in at least one embodiment or example of this application. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0040] In related technologies, ceiling-mounted brackets can usually only fix electronic devices in a preset direction for users to view, or can be opened and closed in one direction to adjust the vertical angle of the electronic device, but cannot adjust the orientation of the electronic device, making it impossible to meet the viewing needs of users in different usage scenarios.

[0041] In view of this, this application provides a rotating device that drives the connecting plate 3 to rotate via the driving component 2, thereby rotating the electronic device and adjusting its orientation to better meet the viewing needs of users in different usage scenarios. Furthermore, the connecting plate 3 of this application can be connected to a common hanging bracket, enabling the electronic device to rotate even with a standard hanging bracket.

[0042] Figure 3 and Figure 4 A rotating device 100 according to an embodiment of this application is shown. Specifically, the rotating device 100 includes a housing 1, a driving assembly 2, and a connecting plate 3. The housing 1 is used for mounting to the ceiling, i.e., the housing 1 is stationary relative to the ceiling. The material of the housing 1 can be metal or other materials with a certain strength. The driving assembly 2 includes a driving member 21, a first transmission member 22, and a second transmission member 23. The driving member 21 is at least partially disposed inside the housing 1 so that the driving member 21 remains relatively stationary with the housing 1. The first transmission member 22 and the second transmission member 23 are in a transmission engagement. The driving member 21 is connected to the first transmission member 22, and the second transmission member 23 is connected to the housing 1 and can rotate relative to the housing 1, so that the driving member 21 can drive the second transmission member 23 to rotate. The connecting plate 3 is disposed on the outside of the housing 1 and fixedly connected to the second transmission member 23. The material of the connecting plate 3 can be metal or other materials with a certain strength. The driving member 21 drives the second transmission member 23 to rotate through the first transmission member 22, thereby driving the connecting plate 3 to rotate, so that the connecting plate 3 can rotate relative to the housing 1.

[0043] For example, please refer to Figure 2 The outer casing 1 can be connected to ceiling screws, and at least some of the screw holes on the outer casing 1 can be gourd-shaped holes with a large diameter end and a small diameter end. During the connection of the outer casing 1 to the ceiling screws, a screw is initially screwed into the large diameter end of the gourd-shaped hole to initially fix the outer casing 1, and then the screw is moved from the large diameter end of the gourd-shaped hole to the small diameter end and the remaining screws are installed into the corresponding screw holes to screw the outer casing 1 to the ceiling.

[0044] In this embodiment, the driving component 21 rotates via a first transmission component 22 and a second transmission component 23, thereby rotating the connecting plate 3. This allows the rotating device 100 to adjust the orientation of the electronic device, better meeting the viewing needs of users in different usage scenarios. Furthermore, the driving component 21 is stationary relative to the outer casing 1. The driving component 21 drives the connecting plate 3 to rotate, causing the connecting plate 3 to rotate relative to the outer casing 1. The surface of the hanging bracket that does not have a rotating function and is connected to the ceiling is usually flat, allowing the connecting plate 3 of this application to be easily and conveniently connected to ordinary hanging brackets, enabling ordinary hanging brackets to also rotate the electronic device.

[0045] In one embodiment, please refer to Figures 3-5 The first transmission component 22 is a driving gear, and the second transmission component 23 includes a driven gear and a transmission shaft 231. The output shaft of the driving component 21 extends toward the connecting plate 3 and is connected to the driving gear. The driving component 21 may include a reducer and a motor, so that the driving component 21 can drive the driving gear to rotate at a low speed with a large torque. The driving component 21 may also be just a motor. The driving gear meshes with the driven gear. The transmission shaft 231 is mounted on the housing 1, the driven gear is connected to the transmission shaft 231, and the connecting plate 3 is connected to the driven gear to drive the connecting plate 3 to rotate. This allows the driven gear to both perform a transmission function and be connected to the connecting plate 3, which helps to reduce the number of related connecting mechanisms of the rotating device 100, and thus helps to reduce the thickness of the rotating device 100.

[0046] For example, the drive shaft 231 can be rotatably connected to the housing 1, and the driven gear is fixedly connected to the drive shaft 231 so that the driving gear can drive the drive shaft 231 to rotate through the driven gear. The connecting plate 3 can be connected to the driven gear, and the connecting plate 3 can also be connected to the drive shaft so that the connecting plate 3 can rotate under the drive of the driving gear.

[0047] For example, such as Figure 4As shown, the drive shaft 231 can also be fixedly connected to the housing 1, and the driven gear is rotatably connected to the drive shaft 231. Under the drive of the driving gear, the driven gear can rotate relative to the drive shaft 231. The connecting plate 3 is connected to the driven gear so that the connecting plate 3 can rotate under the drive of the driving gear. A passive bearing 8 can be provided between the driven gear and the drive shaft 231 to ensure smooth rotation of the driven gear and prevent abnormal noise when the connecting plate 3 rotates.

[0048] For example, the drive member 21 is arranged in a horizontal direction to reduce the thickness of the rotating device 100. The rotation axis of the output shaft of the drive member 21 is arranged in a horizontal direction. The rotating device 100 also includes a reversing gear set so that the drive member 21 can drive the drive gear to rotate and the rotation axis of the drive gear is arranged in a vertical direction.

[0049] For example, please refer to Figure 4 and Figure 5 The driving component 21 drives the active gear to rotate, thereby driving the driven gear to rotate. The connecting plate 3 is connected to the side of the driven gear away from the outer casing 1, so that the connecting plate 3 can also rotate.

[0050] Both the driving gear and the driven gear can be spur gears meshing, or they can be... Figure 5 The helical gear meshing shown is designed to reduce the impact force between the driving gear and the driven gear during meshing.

[0051] For example, please refer to Figure 3 and Figure 4 The driving component 21 is a motor, which includes a motor body and an output shaft. The motor body is located inside the housing 1, and the output shaft passes through the surface of the housing 1 near the connecting plate 3. The driving gear is located between the housing 1 and the connecting plate 3 and is fixedly connected to the output shaft. The driven gear is located outside the housing 1 and meshes with the driving gear. The transmission shaft 231 passes through the surface of the housing 1 near the connecting plate 3, and the driven gear is connected to the part of the transmission shaft 231 that protrudes from the outside of the housing 1.

[0052] It is understood that the first transmission component 22 of this application is not limited to a driving gear, and the second transmission component 23 is not limited to including a driven gear and a transmission shaft 231. In one embodiment, the first transmission component 22 is a worm gear, and the second transmission component 23 includes a worm wheel and a transmission shaft 231. The output shaft of the driving component 21 is connected to the worm gear, and the worm gear and the worm wheel mesh. The transmission shaft 231 is mounted on the housing 1 and can rotate relative to the housing 1. The worm wheel is fixedly connected to the transmission shaft 231. The connecting plate 3 is connected to the worm wheel or the connecting plate 3 is connected to the transmission shaft 231 to drive the connecting plate 3 to rotate. This allows the worm wheel to both perform a transmission function and be connected to the connecting plate 3, which helps to reduce the number of related connecting mechanisms of the rotating device 100, and thus helps to reduce the thickness of the rotating device 100.

[0053] It should be noted that when the worm is used as the first transmission component 22, since the worm and worm wheel themselves are used to transmit the motion and power between the two intersecting shafts, the drive component 21 can be arranged in the horizontal direction and the rotating device 100 may not include the reversing gear set.

[0054] In one embodiment, please refer to Figure 3 and Figure 4 The drive shaft 231 has a cable channel 231a that extends through the drive shaft 231 along its axial direction. The cable channel 231a is used to accommodate at least part of the wires 300 of the electronic device, so that the wires 300 of the electronic device can be routed from inside the housing 1. Consequently, when the connecting plate 3 rotates, the wires 300 accommodated in the cable channel 231a will hardly move relative to the cable channel 231a, thereby reducing the possibility of the wires 300 being pulled and thus reducing the possibility of the wires 300 breaking.

[0055] In one embodiment, please refer to Figure 4 The rotating device 100 includes a first bearing 4, which is disposed between the driven gear and the housing 1 to improve the stability of the driven gear during rotation.

[0056] For example, please refer to Figure 4 The first bearing 4 can be a thrust needle roller bearing. One end of the thrust needle roller bearing is connected to the housing 1 along the axial direction, and the other end is connected to the driven gear to fill the gap between the driven gear and the housing 1. The rotation of the drive assembly 2 driving the connecting plate 3 is usually an eccentric rotation. The thrust needle roller bearing is placed in the gap between the housing 1 and the driven gear, which helps to improve the stability of the driven gear during the eccentric rotation process.

[0057] It is understood that the rotating device 100 is not limited to including the first bearing 4.

[0058] In one embodiment, please refer to Figure 4 The rotating device 100 includes a constraint member 5, which is disposed between the driving gear and the housing 1 to reduce the axial force on the output shaft of the driving member 21 during the meshing process of the driving gear and the driven gear.

[0059] For example, please refer to Figure 4 The constraint member 5 may include a drive bearing and a drive bearing housing. During the assembly of the rotating device 100, the drive bearing can be installed in the drive bearing housing, and then the drive gear can be installed in the drive bearing. The output shaft of the drive member 21 passes through the drive gear, and the drive gear is securely installed in the output shaft of the drive member 21 at the corresponding position using screws.

[0060] It is understood that the rotating device 100 is not limited to including the constraint 5.

[0061] In one embodiment, please refer to Figure 3 The rotating device 100 includes a micro switch 6 and a sensing plate. The micro switch 6 is provided on one of the housing 1 and the connecting plate 3, and the sensing plate is provided on the other. The micro switch 6 is used to stop the rotation of the drive assembly 2. Exemplarily, the micro switch 6 can be provided inside the housing 1, so that the wiring harness that controls the drive assembly 21 to stop is also provided inside the housing 1, without having to pass through the wiring channel 231a of the drive shaft 231. This helps to reduce the amount of wire 300 passing through the wiring channel 231a of the drive shaft 231, thereby reducing the possibility of the wire 300 wearing off and breaking due to rotation. The sensing element is used to trigger the micro switch 6. Exemplarily, the sensing element is disposed on the side of the connecting plate 3 near the driving member 21. The sensing element triggers the micro switch 6 to define the start and end points of the rotation of the connecting plate 3. When the connecting plate 3 rotates, the sensing element disposed on the connecting plate 3 also rotates accordingly. When the sensing element triggers the micro switch 6, the micro switch 6 immediately stops the driving member 21, thereby reducing the possibility of the connecting plate 3 twisting and breaking the electronic device's wire 300 due to a large rotation angle. Exemplarily, the rotatable angle of the connecting plate 3 can be less than or equal to 360°. When the connecting plate 3 rotates 360° to the end point, the connecting plate 3 needs to reverse 360° back to the starting point.

[0062] It is understood that the rotating device 100 is not limited to including the micro switch 6 and the sensing plate; the rotating device 100 may also include a sensor with the same function, using the sensor to control the stop of the driving component 21. Furthermore, the stop of the driving component 21 can also be controlled by calculating the transmission ratio, Hall feedback, or other methods.

[0063] A second aspect of this application provides a ceiling-mounted bracket, including the rotating device 100 and the bracket body 200 described in the foregoing embodiments. Figure 1 The ceiling-mounted bracket is shown in the open position. Figure 5 The ceiling-mounted bracket is shown in its closed state. Specifically, the bracket body 200 includes a mounting frame 220 and an opening / closing device 210. The mounting frame 220 is used to mount electronic devices with displays and cables 300, placing the electronic devices in a prominent position for easy access to information displayed on the screen. The electronic devices can be televisions, monitors, or tablets. The cables 300 can include power cords and signal cables for the electronic devices, which function normally through the cables 300. The mounting frame 220 can be made of plastic or metal, and the electronic devices can be mounted to the mounting frame 220 using screws, clips, or other methods. The mounting frame 220 is positioned on the opening / closing device 210 so that the electronic devices can be suspended in a prominent, preset position. The opening / closing device 210 can drive the mounting frame 220 to rotate along a second rotation axis to expand or retract the mounting frame 220.

[0064] The connecting plate 3 is detachably connected to the opening and closing device 210 to drive the opening and closing device 210 to rotate along the first rotation axis, so that the mounting bracket 220 can rotate along the first rotation axis and the second rotation axis respectively, thereby enabling the electronic device to rotate along the first rotation axis and the second rotation axis respectively. The first rotation axis and the second rotation axis are arranged intersectingly, which is beneficial to meet the viewing needs of users in different usage scenarios.

[0065] For example, please refer to Figure 1 The mounting bracket 220 can be detachably connected to the opening / closing device 210 via screws. When the ceiling-mounted bracket of this application is delivered to the customer, the mounting bracket 220, the opening / closing device 210, and the rotating device 100 can be separated to facilitate the packaging and transportation of the ceiling-mounted bracket, and also to allow the user to adjust the position of the mounting bracket 220 on the opening / closing device 210 according to their own needs. The mounting bracket 220 and the opening / closing device 210 can also be connected, allowing the user to directly install electronic equipment on the mounting bracket 220.

[0066] For example, Figure 3 The axis of rotation shown in R1 is the first axis of rotation. Figure 2 The axis of rotation shown in R2 is the second axis of rotation.

[0067] For example, the first rotation axis may be arranged perpendicular to the second rotation axis.

[0068] It is understood that the bracket body 200 can be directly fixed to the ceiling so that the electronic device can only be extended or retracted along the second rotation axis. The bracket body 200 can also be connected to the rotating device 100 fixed to the ceiling so that the electronic device can rotate along the first rotation axis and the second rotation axis respectively.

[0069] In one embodiment, please refer to Figure 1 , Figure 3 and Figure 5 The opening and closing device 210 includes a rotating component 211, an opening and closing component 212, a connecting rod assembly 214, and a telescopic push rod 213. The connecting plate 3 is detachably connected to the rotating component 211, allowing the rotating component 211 to remain relatively stationary with respect to the connecting plate 3. The opening and closing component 212 is rotatably connected to the rotating component 211 via the connecting rod assembly 214. One axial end of the telescopic push rod 213 is rotatably connected to the opening and closing component 212, and the other axial end is rotatably connected to the rotating component 211, driving the opening and closing component 212 to rotate relative to the rotating component 211 along a second rotation axis. The overall structure is relatively simple. A mounting bracket 220 is disposed on the opening and closing component 212, allowing the mounting bracket 220 to rotate along the second rotation axis.

[0070] In one embodiment, please refer to Figure 1 , Figure 3 and Figure 5 The linkage assembly 214 includes a first hinge 2141, a second hinge 2142, and a third hinge 2143. The two ends of the first hinge 2141 are hinged to the rotating member 211 and the opening / closing member 212, respectively. The two ends of the second hinge 2142 are hinged to the first hinge 2141 and the third hinge 2143, respectively. One end of the third hinge 2143 is hinged to the opening / closing member 212, and the other end of the third hinge 2143 is slidably hinged to the sliding groove 211a of the rotating member 211. (See also...) Figure 5 , Figure 5 This illustration shows a ceiling-mounted bracket in a closed state according to an embodiment of this application. One end of the third hinge 2143 is hinged to the right side of the sliding groove 211a of the rotating member 211. The second hinge 2142 is approximately horizontal. The two ends of the first hinge 2141 are respectively hinged to the rotating member 211 and the opening / closing member 212. As the telescopic push rod 213 gradually extends, driven by the telescopic push rod 213, the opening / closing member 212 rotates around the hinge point between the first hinge 2141 and the rotating member 211. Simultaneously, the hinge point between the third hinge 2143 and the sliding groove 211a gradually moves to the left, causing the second hinge 2142 to rotate clockwise, allowing the opening / closing member 212 to descend as a whole, achieving the desired effect. Figure 1 and Figure 3 The ceiling-mounted bracket is shown in its open state in one embodiment of this application.

[0071] In one embodiment, please refer to Figure 1 and Figure 5 The bracket body 200 has a wiring channel for accommodating at least part of the wires 300 of the electronic device. The wires 300 are constrained within the wiring channel. When the drive assembly 2 drives the bracket body 200 to rotate along the first rotation axis, the bracket body 200 and the wires 300 of the electronic device remain relatively stationary.

[0072] For example, the hub channel 231a can be connected to the wiring channel, and the hub channel 231a and the wiring channel can be used to accommodate different parts of the wire 300 respectively.

[0073] For example, a portion of the wires 300 are disposed in the wiring channel, while another portion of the wires 300 enter the bracket body 200 and are connected to the outside via the cable collection channel 231a. This allows the wires 300 to remain relatively stationary with respect to both the bracket body 200 and the drive shaft 231 when the drive assembly 2 drives the bracket body 200 to rotate along the first rotation axis. Only a circumferential torsion occurs relative to the wires 300. The wires 300 hardly move relative to the bracket body 200 and the drive shaft 231, which helps to reduce the possibility of the wires 300 being pulled.

[0074] Alternatively, the wire 300 may include a first wire and a second wire. One end of the second wire has a first connection terminal for electrical connection with the first wire, and the other end has a second connection terminal for electrical connection with an external power source. At least the second wire is housed within the cable conduit 231a. The first connection terminal of the second wire can be electrically connected to the first wire within the cable conduit 231a, and the first connection terminal of the second wire can also be... Figure 3 As shown, the first wire is electrically connected to the outside of the hub channel 231a so that when the length of the first wire of the electronic device is insufficient to be electrically connected to the external power supply, the first wire can also be electrically connected to the external power supply through the second wire, thereby improving the applicability of the ceiling bracket.

[0075] It should be noted that keeping the support body 200 and the cable 300 relatively stationary means that the cable 300 will hardly move relative to the support body 200.

[0076] In this embodiment, at least a portion of the wire 300 is constrained within the wiring channel of the bracket body 200. This ensures that when the drive assembly 2 drives the bracket body 200 to rotate, the wire 300 rotates synchronously with the bracket body 200. Consequently, during the rotation of the electronic device, the bracket body 200, the electronic device, and the wire 300 rotate synchronously, making the wire 300 less prone to being pulled and reducing the possibility of the wire 300 breaking or falling off the socket. Constraining at least a portion of the wire 300 within the wiring channel also improves the aesthetics of the electronic device mounted on the ceiling-mounted bracket.

[0077] In one embodiment, the wiring channel includes a cable groove formed in the bracket body 200, allowing the cable 300 to be disposed within the cable groove of the bracket body 200. The cable 300 can be snapped into the cable groove, or it can be placed directly within the cable groove; the arrangement method is not limited. Disposing the cable 300 within the cable groove of the bracket body 200 facilitates concealing the electronic device's cable 300 within the bracket body 200, thus improving the aesthetics of the electronic device mounted on the ceiling-mounted bracket.

[0078] In one embodiment, please refer to Figure 1 and Figure 5 The main body 200 of the bracket may also include multiple wire clamps 230, each wire clamp 230 having a through hole 230a. The through holes 230a of each wire clamp 230 together form a wiring channel, that is, the wire 300 passes through the through holes 230a of each wire clamp 230. Under the constraint of the wire clamp 230, the wire 300 is firmly constrained in the wiring channel by its own internal connection strength.

[0079] The wiring channel in this embodiment is formed by the through holes 230a of multiple wire clamps 230. The wires 300 of the electronic device can be constrained at intervals within the through holes 230a of the multiple wire clamps 230 by opening and closing the wire clamps 230, and then the wires 300 are placed in the wiring channel, which helps to improve the convenience of installing the wires 300 in the wiring channel.

[0080] In one embodiment, please refer to Figure 1 and Figure 5 The rotating device 100 includes a protective cover 7, which surrounds the outer periphery of the first transmission member 22 and the second transmission member 23. On the one hand, it can reduce the possibility of dust contaminating the first transmission member 22 and the second transmission member 23, and on the other hand, it can reduce the possibility of lubricating oil splashing during the meshing process of the first transmission member 22 and the second transmission member 23.

Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this application. Furthermore, unless otherwise specified, the embodiments and features described in the embodiments of this application can be combined with each other.
