A horizontal bushing is provided at the center of the upper surface of the bracket, and a limiting rib is provided around the periphery of the horizontal bushing. The first camera host is connected to the bracket through a rotating shaft hole on the housing and the horizontal bushing. Under the drive of the transmission component, the bracket can rotate horizontally relative to the first camera host.

[0008] The horizontal bushing has a surrounding groove around its periphery. The limiting rib is disposed in the groove and separates the two sides of the groove into a cavity. The protrusion of the limiting sheet metal part is inserted into the cavity on the side of the limiting rib and contacts the side of the limiting rib.

[0009] Optionally, the height of the protrusion of the limiting sheet metal part in contact with the side of the limiting rib is at least 1.5 mm.

[0010] Optionally, a shock-absorbing element is provided at the bottom of the arc-shaped mounting groove, the side of the shock-absorbing element is interference-fitted with the inner wall of the arc-shaped mounting groove, and the limiting sheet metal part is provided at the upper part of the shock-absorbing element.

[0011] Optionally, the outer contour edge of the limiting sheet metal part is provided with an upwardly bent flange. When the limiting sheet metal part is installed in the arc-shaped mounting groove, the inner wall of the arc-shaped mounting groove away from the pivot hole is provided with multiple support ribs, and the flange of the limiting sheet metal part is provided with a clearance fit with the support ribs.

[0012] Optionally, the gap between the flange of the limiting sheet metal part and the supporting rib is 0.1~0.2mm, the protrusion of the limiting sheet metal part is a bent flange formed on the inner edge of the limiting sheet metal part, the arc of the protrusion is 8°~12°, and the movable arc range of the limiting sheet metal part is limited within the notch.

[0013] Optionally, the center of the pivot hole is taken as the center of the rotation path of the limiting sheet metal part, and the clockwise or counterclockwise rotation angle of the limiting sheet metal part is half the difference between the arc of the notch and the arc of the protrusion.

[0014] Optionally, the arc of the notch is 32.5°, and the rotatable angle of the limiting sheet metal is 11.25°.

[0015] Optionally, the bracket includes: a first bracket and a second bracket arranged opposite to each other on the left and right.

[0016] Optionally, the bracket is further provided with a pressure plate pre-installed positioning post and a stud located around the pivot hole.

This allows for a further rotation angle beyond the conventional 360-degree angle, facilitating a horizontal rotation range greater than 360°. Attached Figure Description

[0026] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0027] It should be understood that the described embodiments are merely some embodiments of this utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0028] The various embodiments of the present invention described below can be examples of applications in video cameras or other video recording devices, and for ease of description, they are collectively referred to as video cameras, and video cameras are used as examples in the description.

[0029] Figure 1 This is a structural cross-sectional view of an embodiment of the camera of this utility model. The following will be combined with… Figures 1 to 7 The camera provided in the embodiments of this utility model will be described in detail.

[0030] See Figures 1 to 3 and Figure 7 This utility model discloses a camera, which is particularly suitable for scenarios requiring long-term continuous tracking of moving targets or providing panoramic monitoring in complex environments. The camera includes a first camera host 1 and a bracket 2.

[0031] The first camera host 1 includes a housing 11, which can be a rectangular, trapezoidal, streamlined, or other elongated cylindrical structure. The front end of the housing 11 has an opening and a transparent cover to allow for monitoring of the external environment. The transparent cover can be made of high-strength optical glass or polycarbonate material.

[0032] The device includes a camera module, a horizontal rotation drive motor 13, a transmission assembly 14 connected to the output shaft of the horizontal rotation drive motor 13, and a pivot hole 15 located at the bottom of the transmission assembly 14 and extending to the surface of the housing 11. The camera module is used to capture images or videos of a target area. In some embodiments, the camera module is a panoramic camera module, which can realize the monitoring of a large-area scene. The camera module can also be a telephoto module or a thermal imaging module. Since the main technical concept of this invention is to expand its horizontal rotation angle, the type of camera module is not limited to highlight the innovative purpose of this utility model, and will not be specifically described. The transmission assembly 14 can be a gear transmission structure to improve the adjustment precision. The pivot hole 15 is used to connect the bracket 2 and realize its rotation relative to the first camera host. A limiting sheet metal part 16 that can move circumferentially within a predetermined arc along the pivot hole 15 is provided around the pivot hole 15.

[0033] The bracket 2 is a shell structure with a receiving cavity. A second camera host 3, which can rotate vertically relative to the bracket, is installed in the receiving cavity of the bracket, so that the second camera host 3 can rotate vertically relative to the bracket 2 to adjust the pitch angle. A horizontal bushing 21 is provided at the center of the upper surface of the bracket 2. Limiting ribs 22 are evenly distributed on the outer periphery of the horizontal bushing 21. The first camera host 1 is connected to the bracket 2 through the rotating shaft hole 15 on the housing 11 and the horizontal bushing 21.

[0034] The first camera host 1 is connected to the horizontal bushing 21 on the bracket 2 via a pivot hole 15 on the housing 11. At least part of the limiting sheet metal part contacts the side of the limiting rib 22. The size and position design of the pivot hole 15 must ensure a tight fit with the horizontal bushing 21 to provide flexible rotation performance. Driven by the transmission assembly 14, the bracket 2 can rotate horizontally relative to the first camera host 1. During rotation, the limiting sheet metal part interferes with the limiting rib 22. Since the limiting sheet metal part 16 can move circumferentially within a predetermined arc along the pivot hole 15, the limiting rib 22 pushes the limiting sheet metal part 16 to continue rotating by a certain arc, thereby achieving continuous rotation beyond 360° and forming a larger monitoring range.

[0035] See Figure 2In some embodiments, the periphery of the pivot hole 15 is provided with an arc-shaped mounting groove 151, and the limiting sheet metal part 16 is an arc-shaped sheet metal part adapted to the arc-shaped mounting groove 151. The surface of the limiting sheet metal part 16 is provided with a protrusion 161, which is used to contact and collide with the side of the limiting rib 22 during rotation. The limiting sheet metal part 16 is movably installed in the arc-shaped mounting groove 151. A pressure plate 17 is provided above the limiting sheet metal part 16. The pressure plate 17 is used to restrict the movement of the limiting sheet metal part 16 in the vertical direction. The pressure plate 17 is provided with a notch 171 corresponding to the protrusion 161. The limiting sheet metal part 16 can move within the arc range defined by the notch 171, and the protrusion 161 collides with the boundary of the notch 171 to achieve the limitation of the horizontal rotation angle.

[0036] The horizontal bushing 21 of the bracket 2 has a surrounding groove 211. The limiting rib 22 is set in the groove 211, and the limiting rib 22 divides the interior of the groove 211 into two cavities. The protrusion 161 of the limiting sheet metal part 16 is inserted into the cavity on the side of the limiting rib 22 and contacts the side wall of the limiting rib 22, forming an interference collision. Thus, after the bracket rotates horizontally 360 degrees until the limiting rib 22 interferes with the limiting sheet metal part 16, the limiting sheet metal part 16 can be pushed to move in the arc-shaped mounting slide 151, so that the bracket can continue to rotate, thereby achieving an adjustment range greater than 360 degrees of horizontal rotation.

[0037] In some embodiments, the height of the protrusion 161 of the limiting sheet metal part 16 in contact with the side of the limiting rib 22 is at least 1.5 mm, so as to ensure the reliability of the limiting rib 22 in pushing the limiting sheet metal part 16 to continue rotating during the rotation process, and to prevent the contact portion between the limiting rib 22 and the limiting sheet metal part 16 from deforming and failing.

[0038] See Figure 5 In some embodiments, a shock-absorbing element 152 is provided at the bottom of the arc-shaped mounting groove 151. The material of the shock-absorbing element 152 can be high-density EVA, which has excellent shock absorption performance and can maintain elasticity and reduce fatigue deformation in long-term working environments. The side of the shock-absorbing element 152 is interference-fitted with the inner wall of the arc-shaped mounting groove 151, that is, the outline dimension of the shock-absorbing element 152 is slightly larger than the bottom mounting groove width of the arc-shaped mounting groove 151. Optionally, the interference between its side and the inner wall of the groove is more than 0.2mm to prevent the shock-absorbing element 152 from falling out of the arc-shaped mounting groove 151, so as to ensure that the shock-absorbing element 152 reliably achieves shock absorption. The limiting sheet metal part 16 is installed on the upper part of the shock-absorbing element 152, which effectively reduces the vibration and noise that may be generated during rotation, further improving the stability of the camera's horizontal angle adjustment process.

[0039] See Figure 4 and Figure 5 In some embodiments, the outer contour edge of the limiting sheet metal part 16 is provided with an upwardly bent flange 162 to enhance its rigidity and prevent it from deforming during installation. When the limiting sheet metal part 16 is installed in the arc-shaped mounting groove 151, multiple support ribs 153 are provided on the inner wall of the arc-shaped mounting groove 151 away from the pivot hole 15. The flange 162 of the limiting sheet metal part 16 is fitted with the support ribs 153 with a clearance to ensure the stability of the limiting sheet metal part 16 in the arc-shaped mounting groove 151. In addition, the provision of the support ribs 153 can effectively prevent the limiting sheet metal part 16 from shifting significantly due to uneven force, and avoid the limiting sheet metal part 16 from moving around too much in the arc-shaped mounting groove 15.

[0040] In some embodiments, the gap between the flange 162 of the limiting sheet metal part 16 and the support rib 153 is set to 0.1~0.2mm, preferably 0.1mm or slightly larger, to ensure good clearance fit performance, allowing the limiting sheet metal part to move smoothly without causing excessive swaying. The protrusion 161 of the limiting sheet metal part 16 is a bent flange formed on its inner edge, with an arc of 8°~12°, preferably 10°, to meet the requirements of a larger rotation angle.

[0041] The movable arc range of the limiting sheet metal part 16 is restricted within the notch 171 of the pressure plate 17. The limiting control of the rotation angle of the limiting sheet metal part 16 is achieved by restricting the movement range of the protrusion 161.

[0042] Understandably, specifically, the curvature of the protrusion 161 and the curvature of the pressure plate notch 171 together determine the movable range of the limiting sheet metal part 16. Based on the technical concept of this utility model, the curvature of the notch can be adjusted according to the required rotation angle, thereby ensuring that the camera can achieve a larger angle adjustment when rotating horizontally.

[0043] See Figure 4 In some embodiments, the center of the pivot hole 15 is taken as the center of the rotation path of the limiting sheet metal part 16. The rotatable angle of the limiting sheet metal part 16 in the clockwise or counterclockwise direction is half the difference between the arc of the notch 171 of the pressure plate 17 and the arc of the protrusion 161 of the limiting sheet metal part 16. Specifically, the design angle of the pressure plate notch 171 is 32.5°, and the arc of the protrusion 161 of the limiting sheet metal part 16 is designed to be 10°. Therefore, the theoretical rotatable angle of the limiting sheet metal part 16 is (32.5°-10°) / 2=11.25°.

[0044] In this embodiment, through the above design, the rotation path of the limiting sheet metal part 16 is precisely controlled, which enables the camera to achieve a horizontal rotation function of more than 360° on the bracket part.

[0045] See Figure 6 The bracket 2 includes a first bracket 23 and a second bracket 24 arranged opposite each other. The upper part of the first bracket 23 has a hollow structure 231 near its edge, and the upper part of the second bracket 24 has a snap-fit ​​structure 241 near its edge. The snap-fit ​​structure 241 can extend into the hollow structure 231 of the first bracket 23 and engage with it to form a cavity for installing the second camera host 3.

[0046] After the fastening is completed, to further improve the stability of the bracket, the first bracket 23 and the second bracket 24 are locked together using multiple screws 28. In this embodiment, the snap-fit ​​connection between the first bracket 23 and the second bracket 24 has high precision. At the same time, the screws strengthen the locking, which can, to a certain extent, prevent the bracket from "exploding" when it is fastened into a hemisphere, thereby improving the reliability of the entire device.

[0047] See Figure 5 On the bracket 2, at the periphery of the pivot hole 15, there are also pressure plate pre-installed positioning posts 251 and studs 252. The pressure plate pre-installed positioning posts 251 are symmetrically arranged on both sides of the pivot hole 15, and the studs 252 are evenly distributed on the periphery of the pivot hole 15.

[0048] The pressure plate 17 is provided with a pre-installed positioning notch and screw holes 172. The pressure plate 17 completes the initial positioning on the machine housing 11 by cooperating with the pressure plate pre-installed positioning post 251 through the pre-installed positioning notch. The pressure plate pre-installed positioning post 251 and the pre-installed positioning notch have a single-sided gap of 0.1 to prevent the pressure plate from rotating too much on the machine body. Then, the screw 4 passes through the screw hole 172 from above and is locked into the stud 252 to realize the vertical limitation of the limiting sheet metal part and prevent the limiting sheet metal part from falling out of the arc-shaped mounting groove.

[0049] Specifically, the bottom of the pre-installed positioning post 251 on the left side pressure plate of the housing 11 is a long rib to ensure the correct installation direction of the pressure plate 17 and the limiting sheet metal part 16. In addition, in order to ensure the stability of the limiting sheet metal part 16 under long-term operation, its bending height is designed to be 5.8mm, which can meet the requirements of multiple clearances and safety distances.

[0050] In summary, the camera provided by this utility model, through structural improvements, can cover a wider horizontal field of view, avoiding blind spots. It is also suitable for automatically tracking moving targets and enabling long-term continuous monitoring. Furthermore, since a single camera can cover a wider horizontal monitoring area, it can reduce the number of cameras required in scenarios that require multiple cameras, thus lowering costs and complexity.

[0051] Furthermore, when the drive motor control device is connected to the client via a network, the camera's viewing angle can be remotely adjusted to adapt to different monitoring needs.

[0052] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0053] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
