Description

Technical Field

[0001] This utility model relates to the field of mechanical manufacturing, and in particular to a mounting bracket and electronic equipment, specifically a rotatable bracket and an electronic equipment bracket. Background Technology

[0002] With the widespread adoption of smart TVs and mobile devices, users have increasingly higher functional demands for TV stand devices. Many existing TV stand devices suffer from a major drawback: the TV angle cannot be restored. When a TV is subjected to external forces such as manual rotation or impact, its angle position usually cannot be restored to the original set angle when operated via remote control. This affects the user's viewing experience, especially for multi-angle adjustments and usage in different scenarios. Furthermore, many existing TV stands offer limited installation options, typically only supporting ceiling or vertical mounting. In certain installation environments, users find it difficult to flexibly choose a suitable installation method, limiting the stand's applicability and ease of installation.

[0003] With the increasing demand for screen mirroring and mobile phone projection capabilities, users want to be able to cast short videos to their TVs. However, existing stand devices do not effectively support this function. Current technology typically does not offer sufficient angle adjustment and installation flexibility to meet these new user needs.

[0004] Therefore, how to provide a device that can automatically adjust and restore the TV angle, and offer multiple installation methods to meet different usage scenarios, has become an urgent problem to be solved in the bracket industry. Utility Model Content

[0008] The overtaking transmission mechanism C includes a driving gear 23, a driven gear 27, a sliding gear sleeve 26, a fixed sleeve 28, a disc spring 25, a locking nut 24, a motor 29, a fixing pin 30, and a square fixing pin 35. The motor 29 is fixedly mounted on the square tube 17, and its output shaft is connected to the driving gear 23. The driving gear 23 meshes with the driven gear 27. The driven gear 27 has a sliding gear sleeve 26 and a fixed sleeve 28 on its left and right sides, respectively. A disc spring 25 is provided outside the sliding gear sleeve 26, and the disc spring 25 is fixed by the locking nut 24. The sliding gear sleeve 26 is connected to the rotating shaft 7 via the fixing pin 30 and the square fixing pin 35.

[0009] The integrated bearing structure D is located between the rotating shaft 7 and the square tube 17, and consists of a first copper sleeve 6, a second copper sleeve 10 and a round sleeve 9.

[0010] The angle detection mechanism B includes a connecting plate 19, a detection transmission gear 20, a fixing nut 21, and an angle detector 22. The angle detector 22 is mounted on the connecting plate 19 by the fixing nut 21, and the detection transmission gear 20 meshes with the sliding gear sleeve 26 to achieve angle sensing.

[0011] In conjunction with the first aspect, optionally, it also includes: a support panel 3, which is fixed to the rotating shaft 7 by panel fixing screws 8, for supporting components.

[0012] In conjunction with the first aspect, optionally, it also includes:

[0013] The wall panel 1 is used for fixed installation on a wall, which includes a vertical wall, a ceiling wall, or a floor wall.

[0014] In conjunction with the first aspect, optionally, the connecting bracket A is connected to the wall panel 1 via a direct plug-in connection.

[0016] In conjunction with the first aspect, optionally, a surface bearing 31 is also included, which is connected to the rotating shaft 7 and disposed outside the rotating shaft 7.

[0017] In conjunction with the first aspect, optionally, it also includes:

[0018] The forward tilt protection mechanism E includes two oblong holes and one round hole on the left and right fixed adjustment plates 16. The oblong holes are used to adjust the position of the anti-tilt screw 14 to prevent the television from tilting forward unexpectedly.

[0019] In conjunction with the first aspect, optionally, it includes:

[0020] The motor 29 is mounted on the square tube 17 by fixing screws 12, and its output shaft is fixedly connected to the drive gear 23.

[0021] In conjunction with the first aspect, optionally, it includes:

[0022] The detection transmission gear 20 directly meshes with the sliding gear sleeve 26 and is linked with the angle detector 22 to output a voltage signal to the control circuit board 34 to realize angle recognition and control.

[0023] In conjunction with the first aspect, optionally, it includes:

[0024] The sliding gear sleeve 26, driven gear 27, fixed sleeve 28, and disc spring 25 form a sliding friction pair. When the external force is greater than the friction force, the driven gear 27 rotates freely, which protects the motor 29.

[0025] In conjunction with the first aspect, optionally, it includes:

[0026] The control circuit board 34 receives the analog or digital signal output by the angle detector 22 and controls the motor 29 to start or stop according to the set threshold, automatically adjusting the angle so that the bearing panel 3 is precisely adjusted to the target angle.

The carrier panel 3 of the rotatable bracket is provided with an electronic device hanger for supporting a television, display screen, projection screen, player, and electric fan.

[0028] The rotatable bracket and electronic device bracket provided by this utility model achieve significant technical improvements and beneficial effects through the following structural design:

[0029] (1) Through the linkage structure of sliding gear sleeve and angle detector, the current angle position of TV can be sensed in real time, and the motor can be controlled by feedback through control circuit board, so that the TV can automatically return to the preset angle position after being disturbed by external force, thus improving intelligence and convenience.

[0030] (2) Introducing an overrunning transmission mechanism to improve motor safety: The sliding friction pair consisting of a sliding gear sleeve, a fixed sleeve, and a disc spring allows the driven gear to idle when the external force is greater than the friction force, thus achieving mechanical decoupling between the motor and the load, effectively protecting the motor and extending its service life.

[0031] (3) The bearing system is designed as an integrated unit, which is compact and operates smoothly: The bearing system consisting of a round sleeve and a double copper sleeve is embedded in the square tube. The structure is exquisite and saves space, while improving the smoothness of rotation and significantly reducing friction and noise.

[0032] (4) Supports flexible installation in multiple scenarios and adapts to diverse needs: The bracket body supports installation by adjusting the rotating shaft connection structure and the left and right fixed adjustment plates, realizing multiple installation methods such as wall hanging, ceiling hanging, and cabinet installation, truly achieving one machine for multiple uses and scenario compatibility.

[0033] (5) Strong expandability and compatibility with a variety of electronic devices: With the support panel and electronic device bracket, the bracket can be used not only for TVs, but also for monitors, projection screens, electric fans, players and other devices, with good compatibility and potential for widespread application.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0047] Existing TV brackets lack an angle detection and feedback mechanism after the TV is rotated by external force, making it impossible for users to return the TV to the original angle when operating the remote control, thus affecting the user experience. When the TV is intentionally rotated or subjected to external forces such as collisions, traditional drive mechanisms lack an overrun protection structure, easily transmitting reverse torque to the motor and causing damage. Traditional brackets have a simple structure, unable to flexibly adapt to diverse installation needs such as wall mounting, ceiling mounting, and floor mounting, limiting their applicability in complex installation scenarios. Some products lack optimized structural design, resulting in bulky rotating mechanisms, uneven movement, and noise, affecting reliability and user experience.

Figure 8 This diagram illustrates the structure of a rotatable bracket according to an embodiment of the present invention. Figure 1-8 As shown, the rotatable bracket includes: a connecting frame A, which is connected to the wall panel 1 and is provided with a square tube 17 structure;

[0049] The overtaking transmission mechanism C includes a driving gear 23, a driven gear 27, a sliding gear sleeve 26, a fixed sleeve 28, a disc spring 25, a locking nut 24, a motor 29, a fixing pin 30, and a square fixing pin 35. The motor 29 is fixedly mounted on the square tube 17, and its output shaft is connected to the driving gear 23. The driving gear 23 meshes with the driven gear 27. The driven gear 27 has a sliding gear sleeve 26 and a fixed sleeve 28 on its left and right sides, respectively. A disc spring 25 is provided outside the sliding gear sleeve 26, and the disc spring 25 is fixed by the locking nut 24. The sliding gear sleeve 26 is connected to the rotating shaft 7 via the fixing pin 30 and the square fixing pin 35.

[0050] The integrated bearing structure D is located between the rotating shaft 7 and the square tube 17, and consists of a first copper sleeve 6, a second copper sleeve 10 and a round sleeve 9.

[0051] The angle detection mechanism B includes a connecting plate 19, a detection transmission gear 20, a fixing nut 21, and an angle detector 22. The angle detector 22 is mounted on the connecting plate 19 via the fixing nut 21. The detection transmission gear 20 meshes with the sliding gear sleeve 26 to achieve angle sensing.

[0052] In one embodiment, the rotatable bracket further includes a support panel 3, which is fixed to the rotating shaft 7 by panel fixing screws 8, and is used to support the component.

[0053] In one embodiment, the rotatable bracket further includes a wall panel 1 for fixed installation on a wall, the wall including a vertical wall, a ceiling wall, or a floor wall.

[0054] In one embodiment, the rotatable bracket further includes a connecting frame A connected to the wall panel 1 via a direct insertion connection.

[0055] In one embodiment, the rotatable bracket further includes: the connecting frame A further includes a rear cover 15, a left and right fixed adjustment plate 16, and a front cover 18.

[0056] In one embodiment, the rotatable bracket further includes a planar bearing 31, which is connected to the rotating shaft 7 and disposed outside the rotating shaft 7.

[0057] In one embodiment, the rotatable bracket further includes a forward tilt protection mechanism E, comprising two oblong holes and a round hole disposed on the left and right fixed adjustment plates 16, wherein the oblong holes are used to adjust the position of the anti-tilt screw 14 to prevent the television from tilting forward unexpectedly.

[0058] In one embodiment, the rotatable bracket further includes: the motor 29 is mounted on the square tube 17 by fixing screws 12, and its output shaft is fixedly connected to the drive gear 23.

[0059] In one embodiment, the rotatable bracket further includes: the detection transmission gear 20 directly meshes with the sliding gear sleeve 26, and is linked with the angle detector 22 to output a voltage signal to the control circuit board 34 to realize angle recognition and control.

[0060] In one embodiment, the rotatable bracket further includes: the sliding gear sleeve 26, the driven gear 27, the fixed sleeve 28, and the disc spring 25 form a sliding friction pair. When the external force is greater than the friction force, the driven gear 27 rotates freely, which protects the motor 29.

[0061] In one embodiment, the rotatable bracket further includes: the control circuit board 34 receiving the analog or digital signal output by the angle detector 22, and controlling the motor 29 to start or stop according to a set threshold, automatically adjusting the angle so that the support panel 3 is precisely adjusted to the target angle.

[0062] In one specific embodiment, the control circuit board 34 integrates a microcontroller unit (MCU), which is connected to the angle detector 22 and receives the analog or digital angle signal output by the detector. The angle detector 22 employs sensing components such as an encoder or potentiometer, and is mechanically connected to the detection transmission gear 20. It changes synchronously with the rotation of the rotating shaft 7, thereby outputting a signal representing the current angular position of the supporting panel 3.

[0063] During use, when the user issues an angle adjustment command via remote control or panel operation, or when the TV is manually rotated to a non-set angle due to external force, the control circuit board 34 will compare the difference between the current angle output by the angle detector 22 and the preset target angle in real time. If the difference exceeds a set threshold, such as ±2°, the control circuit board will automatically activate the motor 29, drive the drive gear 23 to rotate, and through the transmission relationship with the driven gear 27 and the sliding gear sleeve 26, drive the rotating shaft 7 to rotate, thereby achieving automatic correction of the TV angle.

[0064] For example, if the user sets the TV viewing angle to 0° directly in front, but the TV is rotated to a +15° position due to external force, the system will recognize the deviation and immediately start the motor 29. The motor will slowly rotate the TV back to the 0° position through the gear set, and automatically stop the motor after the angle detector detects the target value again. The whole process does not require user intervention, ensuring accurate viewing angle.

[0065] In another embodiment, the control circuit board 34 can also be set with multiple user-memorized angles, such as "landscape mode 0°" and "portrait mode 90°". Users can select and recall preset angles via buttons or an app, and the motor will automatically adjust to the selected position. This supports one-click switching between landscape and portrait modes, enhancing the intelligence and convenience of use. Furthermore, to avoid jitter or false triggering caused by frequent movements, the control circuit board includes a filtering and delayed start-up program. This ensures that angle correction is only initiated when the angle deviation persists for a certain period, such as more than one second, effectively improving system stability and user experience.

[0066] This utility model device includes several core functional components such as wall panel 1, connecting frame assembly A, bearing panel 3, overtaking transmission mechanism C, angle detection mechanism B, integrated bearing assembly D, and anti-tilting mechanism E.

[0067] The wall panel 1 and the connecting frame A are connected by a direct insertion method. The connecting frame A consists of a rotating shaft 7, a rear cover 15, left and right fixed adjustment plates 16, a square tube 17, and a front cover 18, forming a stable frame structure.

[0068] The bearing panel 3 is fixedly mounted on the front end of the rotating shaft 7 by panel fixing screws 8, and is connected to the rotating shaft by a plane bearing 31 to achieve smooth rotational support. An integrated bearing assembly D is provided between the rotating shaft and the mounting structure. This assembly consists of two copper sleeves 6 and 10 and a round sleeve 9, and is installed inside the square tube 17, which has the functions of saving space and reducing friction and noise.

[0069] The overtaking transmission mechanism C includes components such as a driving gear 23, a driven gear 27, a sliding gear sleeve 26, a fixed sleeve 28, a disc spring 25, a locking nut 24, a motor 29, a fixing pin 30, a square fixing pin 35, a copper sleeve 10, and a rotating shaft 7. The motor 29 is fixedly mounted on the square tube 17 by screws 12, and its output shaft is rigidly connected to the driving gear 23. The driving gear 23 meshes with the driven gear 27 fixed on the rotating shaft 7; the driven gear has a sliding gear sleeve 26 and a fixed sleeve 28 at both ends, with a disc spring 25 on the outer side, forming a pre-tightened friction pair through the locking nut 24. The sliding gear sleeve 26 is connected to the rotating shaft 7 through the fixing pin 30 and the square fixing pin 35, thereby enabling the motor to drive the rotating shaft to rotate.

[0070] When the motor is running, the driving gear 23 drives the driven gear 27 to rotate. With the help of the friction between the sliding gear sleeve 26 and the fixed sleeve 28, the transmission is transmitted to the rotating shaft 7 through the pin structure, driving the TV panel 3 to rotate to the target angle.

[0071] When the TV panel is subjected to external interference, such as being pushed by a person and the external force is greater than the friction force that the above-mentioned friction transmission pair can withstand, the sliding gear sleeve disengages from the rotating shaft, the driven gear 27 idles under the motor output, and the rotating shaft does not rotate, thus forming an overrunning clutch protection to prevent the motor from being damaged by reverse torque.

[0072] The angle detection mechanism B consists of a connecting plate 19, a detection transmission gear 20, an angle detector 22, and a fixing nut 21. The connecting plate 19 is mounted on the square tube 17 by fixing screws 11. The angle detector 22 is mounted on the connecting plate 19 by the fixing nut 21 and is connected to the detection transmission gear 20. The detection transmission gear 20 meshes with the sliding gear sleeve 26. As the rotating shaft rotates, it drives the detection gear to rotate. The angle detector outputs a corresponding voltage signal, which is transmitted to the control circuit board 34. The control circuit adjusts the motor operation according to this signal to ensure that the TV panel reaches the set angle.

[0073] The anti-tilt mechanism E is installed on the left and right fixed adjustment plates 16. It is an adjustable structure composed of two oblong holes and one fixed round hole. The screw installation state at different positions can be adjusted to limit the range of the forward tilt angle and prevent the TV from tilting too much or falling.

[0074] Figure 9 This diagram illustrates the structure of an electronic device bracket according to an embodiment of the present invention; as shown. Figure 9 As shown, the TV stand features a symmetrical vertical support bar design with multiple holes on both sides for adjusting the connection position between the stand and the wall or TV, providing flexible installation adjustments. The fixed frame connects to the TV via a central mechanism, and the screw holes on the frame ensure a secure fixation of the TV. The beveled design at the bottom of the stand enhances stability, preventing the TV from tilting or falling. The multi-hole design and central adjustment mechanism allow the TV's angle, position, or height to be adjusted as needed. Furthermore, the overall structure of the stand is robust and adaptable to different installation environments, ensuring the stability of the TV in various usage scenarios.

[0075] Figure 10 This diagram illustrates the structure of an electronic device bracket according to another embodiment of the present invention, as shown below. Figure 10As shown, the TV stand structure includes a base 37 connected to the TV's fixed frame via a vertical support column 38. The fixed frame 39 is secured to support bars 41 on both sides via the support column 38. The support bars have multiple holes, allowing adjustment of the TV's height and installation position as needed. The support bars 41 are connected to the TV body via the fixed frame, allowing the TV to be adjusted at the desired installation angle. Furthermore, the base 37 provides sufficient stability, ensuring stable support for the TV at different angles and in various usage scenarios. This structure offers high installation flexibility; the multiple adjustable holes allow users to adjust the TV's height and angle according to the installation environment. The base provides stable support, preventing the TV from tilting or falling due to external forces. In addition, the simple design of the stand makes installation and adjustment easier, adapting to various environments and needs, and meeting diverse user installation requirements.

[0076] This utility model also provides an electronic device bracket, including any of the above-described rotatable brackets, with an electronic device hanger provided on the panel 3 of the rotatable bracket for supporting a television, display screen, projection screen, player, and electric fan.

[0077] This invention combines an overtaking transmission mechanism with an integrated bearing, resulting in a more compact and concise overall structure. An integrated bearing is formed by combining a round sleeve and double copper sleeves with a rotating shaft. One end of the rotating shaft connects to a support panel for mounting the television, while the other end has a sliding gear sleeve that meshes with a detection transmission gear and connects to an angle detector. When the television is subjected to external force and rotates, the rotating shaft drives the detection transmission gear. The angle detector monitors this in real time and transmits the current angle data to the control circuit board, thus achieving precise tracking of the television's position. The system then instructs the motor to restore the television to its original set angle. Furthermore, this invention allows for multi-functional installation by changing the rotating shaft connection method (e.g., using a round tube) and adjusting the installation method of the left and right adjustment plates. It can be wall-mounted, ceiling-mounted, or flat-mounted on a countertop, meeting the installation needs of different users and adapting to various usage environments, greatly enhancing the product's applicability and flexibility.
