Description

Technical Field

[0001] This utility model relates to the field of monitoring equipment technology, and in particular to a bracket assembly and a camera device. Background Technology

[0002] In traditional gimbal designs, the constraints of cables prevent the gimbal from achieving infinite, continuous horizontal rotation, necessitating mechanical limiting structures to prevent cable entanglement. However, existing limiting structures themselves restrict the gimbal's rotation angle, preventing it from achieving a full 360-degree rotation. Furthermore, the larger the space occupied by the limiting structure, the more the actual rotation range of the gimbal is compressed. Utility Model Content

[0003] The main purpose of this utility model is to propose a bracket assembly and a camera device, which aims to solve the technical problem that traditional pan-tilt units cannot achieve 360-degree infinite continuous rotation due to cable entanglement.

[0004] To achieve the above objectives, the present invention provides a support assembly comprising: Fixed base; A rotating part for mounting a lens, the rotating part being rotatably disposed on the fixed base; A limiting component includes a first fixing member, a second fixing member, and a limiting member. The first fixing member and the second fixing member are spaced apart from each other on the fixing base. The limiting member is rotatably disposed between the first fixing member and the second fixing member, and the limiting member has a limiting groove. A mating component is provided on the rotating part and is positioned in a first direction corresponding to the position of the limiting groove. It is used to rotate when the rotating part rotates so that the rotating part switches between a first limit position and a second limit position.

[0005] In one embodiment, the limiting member includes a first limiting segment, a second limiting segment, and a third limiting segment. The first limiting segment extends along the first direction and is connected to the first fixing member. The second limiting segment extends along the first direction and is connected to the second fixing member. The third limiting segment extends along the second direction. The first limiting segment, the third limiting segment, and the second limiting segment are sequentially connected to form the limiting groove. The second direction is orthogonal to the first direction.

[0006] In one embodiment, the mating component has a first mating surface and a second mating surface, the first mating surface and the second mating surface being symmetrically arranged about the central axis of the mating component.

[0007] In one embodiment, the first mating surface extends along a third direction and has a first inclined surface, with one end of the first inclined surface away from the rotating part inclined toward the central axis of the mating member; the second mating surface extends along a third direction and has a second inclined surface, with one end of the second inclined surface away from the rotating part inclined toward the central axis of the mating member.

[0008] In one embodiment, the fixing base includes a base and a mounting portion disposed on the base, the rotating portion is rotatably disposed on the mounting portion, and the first fixing member and the second fixing member are disposed on the periphery of the mounting portion and are arranged radially spaced apart.

[0009] In one embodiment, the support assembly further includes a drive assembly, which is motive-connected to the rotating part and is used to drive the rotating part to rotate.

[0010] In one embodiment, the drive assembly includes a gear and a motor, the gear being connected to the rotating part, and the output shaft of the motor meshing with the gear to drive the rotating part to rotate.

[0011] In one embodiment, the motor is located on the side of the fixed base away from the rotating part, and the limiting component is located on the side of the fixed base facing the rotating part.

[0012] This utility model also proposes a camera device, including a lens and a bracket assembly as described above, wherein the lens is disposed on the rotating part.

[0013] In one embodiment, the rotating part has a mounting groove, and the lens is disposed in the mounting groove.

[0014] The technical solution of this utility model involves setting a limiting assembly on a fixed base, consisting of a first fixing member, a second fixing member, and a rotatable limiting member. The limiting member has a limiting groove and can be driven by a mating member on the rotating part to switch between a first posture and a second posture. Taking a downward viewing angle as an example, when the rotating part rotates counterclockwise, the mating member pushes the limiting member to switch to the first posture, causing the opening of the limiting groove to face clockwise, thus allowing the mating member to enter the limiting groove. At this time, the rotating part can reach the first extreme position in the counterclockwise direction. Conversely, when the rotating part rotates clockwise, the limiting member is switched to the second posture, the opening of the limiting groove turns counterclockwise, and the mating member can enter the limiting groove. At this time, the rotating part can reach the second extreme position in the clockwise direction. Crucially, the rotating part can continuously rotate at least 360 degrees between the first and second extreme positions. This means that whenever the rotating part approaches its limit position in a certain direction, the limiting component switches to the corresponding posture under the action of the mating component, so that the opening faces the direction of rotation, thereby allowing the mating component to enter and be confined within the limiting groove, thus achieving the limit position limitation in the corresponding direction. In this way, the limiting component no longer rigidly restricts the rotation range in the form of a fixed stop, but actively provides a limiting channel when needed through rotatable posture switching. This can prevent the cable from getting tangled due to excessive rotation, and also avoid the permanent occupation and compression of the total rotation angle by the traditional fixed limiting structure. Since the rotating part itself can independently rotate at least 360 degrees between the first and second limit positions, after completing a scan in one direction, the rotating part can continue to rotate in another direction without being affected by the previous limiting state, thereby achieving flexible rotation over a wide range or even multiple consecutive rotations, improving the degree of freedom of movement and operational reliability of the support assembly.

[0022] In traditional gimbal designs, the constraints of cables prevent the gimbal from achieving infinite, continuous horizontal rotation, necessitating mechanical limiting structures to prevent cable entanglement. However, existing limiting structures themselves restrict the gimbal's rotation angle, preventing it from achieving a full 360-degree rotation. Furthermore, the larger the space occupied by the limiting structure, the more the actual rotation range of the gimbal is compressed.

[0023] Therefore, this utility model proposes a support assembly 100, which aims to solve the technical problem that traditional gimbals cannot achieve 360-degree infinite continuous rotation due to cable entanglement.

[0024] Please see Figures 1 to 11 In one embodiment of the present invention, the support assembly 100 includes: Fixture 1; Rotating part 2 is used to mount the lens, and rotating part 2 is rotatably mounted on fixed base 1; The limiting component 3 includes a first fixing member 31, a second fixing member 32 and a limiting member 33. The first fixing member 31 and the second fixing member 32 are spaced apart on the fixing base 1. The limiting member 33 is rotatably disposed between the first fixing member 31 and the second fixing member 32. The limiting member 33 has a limiting groove 301. The mating part 4 is provided on the rotating part 2 and is positioned in a first direction corresponding to the position of the limiting groove 301. It is used to rotate when the rotating part 2 rotates so that the rotating part 2 switches between the first limit position and the second limit position.

[0025] like Figure 1 As shown, the fixing seat 1 serves as the base structure of the entire support assembly 100. It can be made of metal die casting or high-strength plastic injection molding. It is installed on an external support structure, such as a wall or pole, to support and connect all other components of the support assembly 100, ensuring the stability and vibration resistance of the overall structure.

[0026] like Figure 1 As shown, the rotating part 2 is used to mount the lens. It is rotatably mounted on the fixed base 1 via a central rotating shaft and bearing structure. The rotating part 2 can rotate horizontally around its own vertical axis, thereby driving the lens to rotate synchronously and adjusting the lens azimuth angle. The rotation of the rotating part 2 is powered by a built-in drive motor, which is transmitted through gear 51. Alternatively, a rack and pinion drive or direct drive can be used to control the rotation angle of the lens, thereby adjusting the lens angle of view.

[0027] like Figure 2 and Figure 3 As shown, the limiting component 3 consists of a first fixing member 31, a second fixing member 32, and a limiting member 33. The first fixing member 31 and the second fixing member 32 are respectively mounted on the fixed base 1, maintaining a certain distance and arranged relative to each other. The first fixing member 31 and the second fixing member 32 can be support plates or bosses with shaft holes, used to support the limiting member 33, allowing it to rotate between the first fixing member 31 and the second fixing member 32. The limiting member 33 is a rotatable independent component, for example, designed as a disc-shaped or cam-shaped structure with a central shaft. The two ends of the limiting member 33 are respectively installed in the shaft holes of the first fixing member 31 and the second fixing member 32 through bushings or bearings, thereby achieving a rotatable connection. The limiting member 33 is provided with a limiting groove 301, which can be an arc-shaped groove, a U-shaped notch, or a through hole, etc., its function is to provide a space for the mating part 4 to enter and be accommodated, thereby limiting the rotational limit position of the mating part 4.

[0028] like Figures 2 to 4 As shown, the mating part 4 is installed on the rotating part 2 and can be in the form of an outwardly protruding pin, protruding post or roller. Its installation position corresponds to the limiting groove 301 along the first direction, where the first direction is the circumferential direction of the rotating part 2, that is, the circumferential direction around the rotation axis of the rotating part 2.

[0029] Viewed from below, such as Figures 5 to 9 As shown, when the rotating part 2 drives the lens to rotate counterclockwise, the mating part 4 rotates synchronously with the rotating part 2. During the rotation, when the rotating part 2 approaches the maximum allowable angle in the counterclockwise direction, the mating part 4 contacts the limiting member 33 and applies a pushing force, causing the limiting member 33 to rotate and switch to the first posture. In this posture, the opening 302 of the limiting groove 301 is in the clockwise direction and corresponds to the mating part 4, allowing the mating part 4 to smoothly enter the limiting groove 301. At this time, the rotation of the rotating part 2 is restricted, reaching the first limit position, preventing excessive twisting of the cable due to counterclockwise rotation.

[0030] Similarly, such as Figure 10 and Figure 11As shown, when the rotating part 2 rotates clockwise to the second limit position, the mating part 4 pushes the limiting part 33 from the other side, causing it to switch to the second posture. At this time, the opening 302 of the limiting groove 301 turns counterclockwise, the mating part 4 enters the limiting groove 301, and the rotating part 2 is limited to the second limit position. Crucially, the rotating part 2 can rotate continuously for at least 360 degrees between the first and second limit positions. This means that whenever the rotating part 2 approaches the limit position in a certain direction, the limiting part 33 switches to the corresponding posture under the push of the mating part 4, causing the opening 302 to face the opposite direction of that rotation, thereby allowing the mating part 4 to enter and be limited in the limiting groove 301, achieving the limitation of the limit position in the corresponding direction. In this way, the limiting part 33 no longer rigidly restricts the rotation range as a fixed stop, but actively provides a limiting channel when needed through rotatable posture switching. This prevents the cable from tangling due to excessive rotation and avoids the permanent occupation and compression of the total rotation angle by traditional fixed limiting structures. Since the limiting member 33 can rotate independently between the first limit position and the second limit position by no less than 360 degrees, after the rotating part 2 completes the scanning in one direction, it can continue to rotate in another direction without being affected by the previous limiting state, thereby achieving flexible rotation over a wide range or even multiple consecutive rotations, improving the degree of freedom of movement and working reliability of the bracket assembly 100.

[0031] Please see Figures 1 to 11 In one embodiment of the present invention, the limiting member 33 includes a first limiting segment 331, a second limiting segment 332 and a third limiting segment 333. The first limiting segment 331 extends along a first direction and is connected to a first fixing member 31. The second limiting segment 332 extends along the first direction and is connected to a second fixing member 32. The third limiting segment 333 extends along a second direction. The first limiting segment 331, the third limiting segment 333 and the second limiting segment 332 sequentially form a limiting groove 301. The second direction is orthogonal to the first direction.

[0032] In this embodiment, as Figure 3As shown, the limiting member 33 includes a first limiting segment 331, a second limiting segment 332, and a third limiting segment 333. The third limiting segment 333 connects the first limiting segment 331 and the second limiting segment 332 to form an integral frame structure. The first limiting segment 331 extends along a first direction and is connected to the first fixing member 31. The second limiting segment 332 also extends along the first direction and is connected to the second fixing member 32, so that the first limiting segment 331 and the second limiting segment 332 are arranged in a parallel or approximately parallel layout in space, together forming the two main support arms of the limiting member 33 in the first direction. The third limiting segment 333 extends along a second direction, which intersects with the first direction, preferably orthogonally, so that the third limiting segment 333 spans between the first limiting segment 331 and the second limiting segment 332, connecting them into an integral structure similar to a "U" shape or a "door".

[0033] In this structure, the third limiting segment 333 not only serves to connect and enhance the overall rigidity, but more importantly, the first limiting segment 331, the third limiting segment 333, and the second limiting segment 332 sequentially form a limiting groove 301. The limiting groove 301 can be an arc-shaped groove, a U-shaped groove formed by the recess of the limiting member 33, or a guide channel formed by its sidewalls. The limiting groove 301 is used to accommodate the mating member 4. When the rotating part 2 rotates to the first limit position or the second limit position, the mating member 4 enters the limiting groove 301, achieving the end point limitation of the rotation stroke.

[0034] In the specific work process, when observing from a tilting angle, such as Figures 5 to 9 As shown, when the rotating part 2 rotates counterclockwise to near the first limit position, the mating part 4 contacts one side of the third limiting segment 333 and applies a pushing force, pushing the entire limiting part 33 to rotate around its central axis between the first fixing part 31 and the second fixing part 32, causing the limiting part 33 to switch from the initial posture to the first posture. When the limiting part 33 rotates to the first posture, the opening 302 of the limiting groove 301 turns clockwise, forming an entry channel aligned with the counterclockwise rotation path, allowing the mating part 4 to smoothly enter the limiting groove 301 and be stably confined therein, thereby enabling the rotating part 2 to reach the first limit position in the counterclockwise direction. Similarly, as Figure 10 and Figure 11 As shown, when the rotating part 2 rotates clockwise and approaches the second limit position, the mating part 4 contacts the third limiting segment 333 from the other side, pushing the limiting part 33 to rotate in the opposite direction, thus switching it from the initial posture to the second posture. The opening 302 of the limiting groove 301 then turns counterclockwise, and the mating part 4 enters the limiting groove 301 and is confined therein, so that the rotating part 2 reaches the second limit position in the clockwise direction.

[0035] Since the first limiting segment 331 and the second limiting segment 332 are respectively connected to the first fixing member 31 and the second fixing member 32, and both extend along the first direction, they can provide stable dual-point support for the limiting member 33, ensuring that it does not tilt or wobble during rotation. The third limiting segment 333 extends along the second direction orthogonal to the first direction and forms a limiting groove 301 with the first limiting segment 331 and the second limiting segment 332, so that the position and orientation of the limiting groove 301 can be dynamically adjusted with the rotation of the limiting member 33, realizing active guidance and direction switching of the mating part 4's entry path.

[0036] Please see Figures 1 to 11 In one embodiment of the present invention, the mating component 4 has a first mating surface 401 and a second mating surface 402, and the first mating surface 401 and the second mating surface 402 are symmetrically arranged about the axis of the mating component 4.

[0037] In this embodiment, as Figure 4 As shown, the first mating surface 401 and the second mating surface 402 are symmetrically arranged about the axis of the mating member 4, so that the first mating surface 401 and the second mating surface 402 are mirror symmetrical in space, located on both sides of the mating member 4, and evenly distributed with their own axes as the center. This symmetrical layout can ensure that the interaction force between the mating member 4 and the limiting member 33 is highly consistent and balanced when the mating member 4 moves clockwise or counterclockwise as it rotates with the rotating part 2.

[0038] Please see Figures 1 to 3 In one embodiment of the present invention, the first mating surface 401 extends along a third direction and has a first inclined surface 4011. The end of the first inclined surface 4011 away from the rotating part 2 is inclined toward the central axis of the mating part 4. The second mating surface 402 extends along a third direction and has a second inclined surface 4021. The end of the second inclined surface 4021 away from the rotating part 2 is inclined toward the central axis of the mating part 4.

[0039] like Figures 4 to 9As shown, viewed from a pitch angle, when the rotating part 2 approaches the first limit position in a counterclockwise direction, the first mating surface 401 contacts the third limiting segment 333. The first mating surface 401 extends in a third direction and has a first inclined surface 4011. The first inclined surface 4011 is inclined from the end away from the rotating part 2 toward the central axis of the mating member 4, with its extension direction as a reference, and forms a first guide angle with the extension direction of the first mating surface 401. When the inclined surface corresponding to the first guide angle contacts the third limiting segment 333, a thrust can be applied to the third limiting segment 333. Due to the guiding effect of the first guide angle, the limiting member 33 rotates toward the side away from the rotating part 2, and is pushed by the mating member 4 until it reaches the first posture. As the rotating part 2 continues to rotate counterclockwise, the first mating surface 401 continuously pushes the third limiting segment 333, causing the limiting member 33 to gradually rotate to the first posture. At this time, the opening 302 of the limiting groove 301, formed by the sequential connection of the first limiting segment 331, the third limiting segment 333, and the second limiting segment 332, turns clockwise, providing a channel for the mating member 4 to enter. When the limiting groove 301 is completely aligned with the rotation path, the mating member 4 slides into the limiting groove 301 along the first direction, causing the rotating part 2 to reach the first limit position.

[0040] like Figure 4 , Figure 10 and Figure 11 As shown, when the rotating part 2 rotates clockwise and approaches the second limit position, the second mating surface 402 contacts the third limiting segment 333. The second mating surface 402 extends in the third direction and has a second inclined surface 4021. The second inclined surface 4021 is inclined from the end away from the rotating part 2 toward the central axis of the mating member 4, with the extension direction of the second mating surface 402 as a reference, and a second guide angle is formed between its extension direction and the extension direction of the second mating surface 402. The thrust applied after the second guide angle contacts the third limiting segment 333 causes the limiting member 33 to rotate in the opposite direction, switching to the second posture, so that the opening 302 of the limiting groove 301 turns counterclockwise. Subsequently, the mating member 4 smoothly enters the limiting groove 301 in the first direction during rotation, so that the rotating part 2 reaches the second limit position.

[0041] Please see Figures 1 to 3 In one embodiment of the present invention, the fixed base 1 includes a base 11 and a mounting portion 12 disposed on the base 11. The rotating portion 2 is rotatably disposed on the mounting portion 12. The first fixing member 31 and the second fixing member 32 are disposed on the periphery of the mounting portion 12 and are arranged radially at intervals.

[0042] In this embodiment, the base 11 serves as the basic support structure for the entire bracket assembly 100, used to mount the bracket assembly 100 onto a wall, ceiling, or other support structure. The mounting portion 12 is located on the base 11 and supports the rotating portion 2, allowing the rotating portion 2 to rotate around the axis of the mounting portion 12. The first fixing member 31 and the second fixing member 32 are disposed around the periphery of the mounting portion 12 and are radially spaced, where the radial direction is the radial direction of the bracket assembly 100, i.e., the radial direction of the rotating portion 2. This arrangement not only provides a mounting base for the limiting member 33 but also ensures that the limiting member 33 can rotate smoothly between the first fixing member 31 and the second fixing member 32 without being subject to additional obstruction or interference.

[0043] Please see Figures 1 to 3 In one embodiment of the present invention, the bracket assembly 100 further includes a drive assembly 5, which is drivenly connected to the rotating part 2 and is used to drive the rotating part 2 to rotate.

[0044] In one embodiment, the drive assembly 5 may consist of a motor and a transmission mechanism. The motor is mounted on the fixed base 1 and may be a DC motor, a stepper motor, or a brushless motor. The transmission mechanism includes a gear set 51, a synchronous pulley, or a worm gear, etc., wherein the motor output shaft is connected to a gear, and the pinion meshes with the gear 51 fixed on the rotating part 2. Power is transmitted to the rotating part 2 through the gear 51, thereby driving the rotating part 2 to rotate around the central axis of the mounting part 12.

[0045] When the drive assembly 5 receives a horizontal steering command from an external control device, it can start according to the command direction. If it needs to observe to the left, the motor drives the rotating part 2 to rotate counterclockwise; if it needs to scan to the right, the motor drives the rotating part 2 to rotate clockwise. This active drive method allows the bracket assembly 100 to automatically adjust the lens's shooting angle without manual intervention, realizing remote control and cruise functions.

[0046] Please see Figures 1 to 3 In one embodiment of this utility model, the motor is located on the side of the fixed base 1 away from the rotating part 2, and the limiting component 3 is located on the side of the fixed base 1 facing the rotating part 2.

[0047] In this embodiment, the motor is located on the side of the fixed base 1 facing away from the rotating part 2, and can be fixed by screws or clips. The motor does not occupy the radial space around the rotating part 2, making the arrangement of the limiting component 33 and the mating component 4 more flexible, avoiding structural crowding and assembly conflicts. At the same time, since the limiting component 3 is located on the side of the fixed base 1 facing the rotating part 2, independent of the motor, even during motor operation, the mating component 4 can rotate freely and independently without being obstructed by the motor, ensuring that it can continuously rotate no less than 360 degrees between the first limit position and the second limit position, truly achieving dynamic avoidance and infinite reset capability.

[0048] This utility model also proposes a camera device; please refer to [link / reference needed]. Figures 1 to 3 The camera device includes a lens and a support assembly 100. The specific structure of the support assembly 100 is as described in the above embodiments. Since this camera device adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, and will not be described in detail here. The lens can be fixedly installed on the rotating part 2 or detachably installed on the rotating part 2, and the specific installation is not limited here.

[0049] Please see Figures 1 to 3 In one embodiment of the present invention, the rotating part 2 has a mounting groove 201, and the lens is disposed in the mounting groove 201.

[0050] In this embodiment, the mounting groove 201 can be a recessed structure formed inside the rotating part 2, the shape of which is adapted to the outer contour of the lens, and can be circular, elliptical, or irregular, for accommodating and fixing the lens. The mounting groove 201 can be opened along the axial direction or oblique direction of the rotating part 2, the specific direction depending on design requirements and space layout optimization. The lens can be fixed in the mounting groove 201 by interference fit, threaded connection, or snap-fit ​​structure to ensure that it remains stable and does not loosen during the operation of the bracket assembly. In order to further improve the waterproof, dustproof and shockproof performance, some embodiments may also be provided with sealing rings or buffer pads. These measures help protect the lens from the influence of the external environment and adapt to long-term operation in various complex indoor and outdoor environments.

[0051] By installing the lens using the mounting slot 201, not only can the ease of lens installation and removal be improved, but it is also easier to position and adjust the lens. This allows the center of the lens optical axis to be closer to the rotation axis of the rotating part 2, thereby reducing the extra load caused by eccentricity and improving the smoothness and response speed of its movement.

[0052] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
