Description

Technical Field

[0001] The present invention relates to the technical field of monitoring cameras, and more particularly to an adjustable security monitoring camera. Background Art

[0002] In existing technologies, security surveillance cameras typically use a single-axis hinge structure to achieve angle adjustment. Its core support relies on the direct connection between the hinge point and the camera body. For example, common outdoor surveillance equipment uses the hinge axis and bearing seat to allow the camera to be manually or electrically adjusted in the horizontal and pitch directions. However, this type of security surveillance camera still has certain drawbacks: The single-axis hinge structure bears the entire load of the camera body at its left and right hinge points. In high-vibration environments such as transportation hubs or industrial workshops, the camera is susceptible to localized stress overload on the hinge axis due to the continuous impact of vehicles passing or equipment operation. The contact surface between the hinge axis and the bearing seat is susceptible to fatigue cracking or even fracture due to long-term bending moment. Furthermore, the single-point support makes the camera body poorly able to withstand lateral wind loads. In outdoor security scenarios, strong winds (such as those in coastal typhoon environments) can cause the camera to swing significantly, blurring the surveillance footage. If the hinge axis fails, the camera can even fall, posing a significant safety hazard. Summary of the Invention

[0003] The present invention provides an adjustable security monitoring camera to solve the above technical problems.

[0004] The present invention provides an adjustable security monitoring camera, comprising a mounting frame and a main rotating frame rotatably mounted on the front side of the mounting frame, an arc-shaped frame rotatably mounted between the left and right inner walls of the main rotating frame, an articulated frame fixedly mounted on the bearing seat of the arc-shaped frame, a camera body hingedly connected between the left and right articulated frames, an arc-shaped slide rail fixedly mounted on the front side of the main rotating frame, a locking reinforcement portion connected to the camera body to form a triangular locking reinforcement structure is provided between the arc-shaped slide rail and the arc-shaped frame.

[0005] The locking reinforcement portion includes a locking assembly for locking the angle of the camera body after the angle adjustment is completed and a driving assembly for driving the locking assembly.

[0006] Furthermore, the locking assembly includes a sliding box slidably installed in the arc-shaped slide rail, a locking member is slidably installed in the sliding box, a return spring is fixedly installed on the side of the locking member away from the mounting frame, and a toggle block is fixedly installed on the other end of the return spring.

[0007] Furthermore, the locking member is composed of an I-shaped segment and two left-right symmetrical U-shaped segments, and the return spring is fixedly installed on the inner wall of the opening side of the I-shaped segment.

[0008] Furthermore, two left-right symmetrical toggle members are vertically rotatably installed in the sliding box, two left-right symmetrical toggle slots are opened on the toggle block, and one end of the toggle member close to the toggle slot is slidably connected to the toggle slot.

[0009] Furthermore, connecting rods sliding through the arc-shaped slide rails are fixedly installed on the left and right sides of the sliding box, and a round rod fixedly connected to the two connecting rods is fixedly installed on the rear side of the camera body.

[0010] Furthermore, a square groove is provided on the rear side of the arc-shaped frame, and the round rod is slidably installed in the square groove.

[0011] Furthermore, the drive assembly includes a guide rod fixedly mounted on the side of the U-shaped section of the locking member away from the mounting frame. The ends of the two guide rods away from the mounting frame both slide through the mounting frame and are jointly mounted with a guide sleeve.

[0012] Furthermore, the toggle block slides through the sliding box on a side away from the mounting frame and is fixedly mounted with a pressure block, and a conical surface is provided on the pressure block on a side away from the toggle block.

[0013] Furthermore, a connecting frame is fixedly installed on the rear side of the arc frame, and an L-shaped pressure plate symmetrically installed on the side of the connecting frame away from the arc frame. The two L-shaped pressure plates are both provided with a slope surface that matches the conical surface on the toggle block on the adjacent side.

[0014] Furthermore, sliding grooves are provided on both the left and right sides of the arc-shaped slide rail, and two connecting rods are slidingly connected to the corresponding sliding grooves respectively.

[0015] The beneficial effects of the present invention are: 1. In the present application, after the locking mechanism is locked, the camera body forms a three-point support structure through the left and right hinge points and the locking member. The straight-line distances between the three points are evenly distributed, forming an isosceles triangle, thereby significantly improving the overall rigidity of the hinge structure of the arc-shaped slide rail, locking mechanism, arc frame and camera body. When the camera is impacted by external force, the load is dispersed along the triangular frame to the main rotating frame, arc-shaped slide rail and arc frame, avoiding stress concentration on a single hinge point, and upgrading the linear force mode of the traditional single-axis hinge to a surface load distribution. The friction locking between the locking member and the inner wall of the arc-shaped slide rail forms a double anti-deformation protection, which greatly improves the strength, stability and safety of the camera body under the action of external force.

[0016] 2. In this application, the rotational action of the arc frame is deeply coupled with the response of the locking assembly to achieve full-process automation of automatic unlocking-angle adjustment-precise locking and form a three-point support structure. During adjustment, the slope of the L-shaped pressure plate and the conical surface of the pressure block cooperate to convert the rotational force into the lateral displacement of the locking member. When locking, the elastic reset of the reset spring and the friction self-locking act synchronously to ensure that the locking force is evenly distributed, thereby greatly improving the stability of the camera body.

[0024] The subject matter described herein will now be discussed with reference to example embodiments. It should be understood that these embodiments are discussed to enable those skilled in the art to better understand and implement the subject matter described herein. The functions and arrangements of the elements discussed may be varied without departing from the scope of protection of this specification. Various examples may omit, substitute, or add various processes or components as needed. In addition, features described with respect to some examples may also be combined in other examples.

[0025] See Figure 1 、 Figure 2 and Figure 3 In this embodiment, an adjustable security surveillance camera is proposed, including a mounting frame 1 and a main rotating frame 2 rotatably mounted on the front side of the mounting frame 1, an arc frame 3 is rotatably mounted between the left and right inner walls of the main rotating frame 2, an articulated frame 4 is fixedly mounted on the bearing seat of the arc frame 3, a camera body 5 is hingedly connected between the left and right articulated frames 4, an arc slide 6 is fixedly mounted on the front side of the main rotating frame 2, and a locking reinforcement portion 7 is provided between the arc slide 6 and the arc frame 3 to form a triangular locking reinforcement structure connected to the camera body 5.

[0026] It should be noted that the main rotating frame 2 and the arc frame 3 are each driven by independent motors via belt drives. During circumferential adjustment, the motor of the main rotating frame 2 drives it to rotate around the axis of the mounting frame 1 via a belt, achieving azimuth adjustment of the camera. During pitch adjustment, the motor of the arc frame 3 drives the arc frame 3 to rotate around the bearing seat of the main rotating frame 2, thereby driving the camera body 5 to change the pitch angle around the articulated frame 4 through the locking reinforcement 7. The surface of the hinge axis between the camera body 5 and the articulated frame 4 is knurled, which cooperates with the high-friction coefficient bushing (polyurethane-copper alloy composite) of the articulated seat to increase friction, preventing the articulated axis from rotating in its natural state when not subjected to external forces.

[0027] See Figure 3 、 Figure 4 、 Figure 5 and Figure 6 The locking reinforcement part 7 includes a locking assembly 71 for locking the angle of the camera body 5 after the angle adjustment is completed. The locking assembly 71 includes a sliding box 711 slidably installed in the arc slide rail 6. A locking member 712 is slidably installed in the sliding box 711. A reset spring 713 is fixedly installed on the side of the locking member 712 away from the mounting frame 1, and a toggle block 714 is fixedly installed on the other end of the reset spring 713.

[0028] See Figure 3 、 Figure 4 、 Figure 5 and Figure 6 The locking member 712 is composed of an I-shaped segment and two U-shaped segments that are symmetrical (eg Figure 5 and Figure 6 (As shown in the middle cross-sectional view), the return spring 713 is fixedly mounted on the inner wall of the opening side of the cross-shaped segment.

[0029] It should be noted that the contact surface between the "X"-shaped section of the locking member 712 and the inner wall of the arc-shaped slide rail 6 is provided with an anti-slip pad to increase the locking friction.

[0030] See Figure 3 、 Figure 4 、 Figure 5 and Figure 6Two symmetrical toggle members 715 are vertically and rotatably installed in the sliding box 711, and two symmetrical toggle slots are opened on the toggle block 714. The toggle member 715 is slidably connected to the toggle slot at one end thereof.

[0031] It should be noted that the toggle member 715 is mounted in the sliding box 711 via a vertical axis and can rotate around the axis (e.g. Figure 6 (Partially enlarged view), when the toggle block 714 is moved by external force, its toggle groove squeezes one end of the toggle member 715 that is slidably connected to it, forcing the toggle member 715 to rotate around the axis, thereby driving the locking member 712 to move laterally to achieve locking or release.

[0032] See Figure 3 、 Figure 4 、 Figure 5 and Figure 6 The left and right sides of the sliding box 711 are fixedly installed with connecting rods 716 that slide through the arc-shaped slide rail 6, and the rear side of the camera body 5 is fixedly installed with a round rod 717 fixedly connected to the two connecting rods 716.

[0033] See Figure 3 、 Figure 4 、 Figure 5 and Figure 6 A slide groove 8 is provided on both sides of the left and right sides of the arc-shaped slide rail 6, and two connecting rods 716 are slidably connected to the corresponding slide grooves 8 respectively.

[0034] It should be noted that the arc length of the slide groove 8 matches the maximum pitch angle of the camera body 5 (can be freely set according to needs, preferably 60°). When the connecting rod 716 slides in the slide groove 8, the round rod 717 moves synchronously along the square groove of the arc frame 3.

[0035] See Figure 3 、 Figure 4 、 Figure 5 and Figure 6 A square groove is provided on the rear side of the arc frame 3, and the round rod 717 is slidably installed in the square groove.

[0036] It should be noted that the square groove not only limits the round rod 717 to enhance the stability of the angle adjustment of the camera body 5, but also provides travel space for the movement of the locking mechanism.

[0037] See Figure 3 、 Figure 4 、 Figure 5 and Figure 6The locking reinforcement part 7 also includes a driving component 72 for driving the locking component 71. The driving component 72 includes a guide rod 721 fixedly installed on the side of the U-shaped section of the locking member 712 away from the mounting frame 1. The two guide rods 721 slide through the mounting frame 1 at one end away from the mounting frame 1 and are jointly installed with a guide sleeve 722.

[0038] See Figure 3 、 Figure 4 、 Figure 5 and Figure 6 The toggle block 714 slides through the sliding box 711 on the side away from the mounting frame 1 and is fixedly installed with a pressure block 723. The pressure block 723 is provided with a conical surface on the side away from the toggle block 714. A connecting frame 724 is fixedly installed on the rear side of the arc frame 3. The connecting frame 724 is fixedly installed with an L-shaped pressure plate 725 symmetrical in upper and lower directions on the side away from the arc frame 3. The two L-shaped pressure plates 725 are both provided with a slope surface that matches the conical surface on the toggle block 714 on the side close to each other.

[0039] The operating principle of the present invention is now described as follows: When the pitch adjustment of the camera body 5 is performed, the motor drives the arc frame 3 to rotate, and the arc frame 3 drives the upper and lower symmetrical L-shaped pressure plates 725 to move synchronously through the connecting frame 724 on the rear side. The slope surface of the corresponding L-shaped pressure plate 725 contacts the conical surface of the pressure block 723, exerting an inward extrusion force, forcing the pressure block 723 to move toward the side close to the sliding box 711, thereby driving the toggle block 714 to move synchronously, and then squeezing the toggle member 715 through the toggle groove, causing the toggle member 715 to rotate around its axis, so that the toggle member 715 is away from the toggle groove. The U-shaped section of the locking member 712 slides toward the side close to the arc frame 3. At this time, the "F"-shaped section of the locking member 712 disengages from the inner wall of the arc slide rail 6, the return spring 713 is compressed, and the pitch angle of the camera body 5 enters a freely adjustable state.

[0040] Then, as the arc frame 3 continues to rotate, when the L-shaped pressure plate 725 contacts the side wall of the sliding box 711, the arc frame 3 continues to rotate, pushing the sliding box 711 to move. This in turn drives the camera body 5, through the connecting frame 724 and the round rod 717, to rotate and adjust the pitch angle around the hinge point between the camera body 5 and the articulated frame 4. When the camera body 5 is adjusted to the target pitch angle, the motor drives the arc frame 3 to rotate slightly in the opposite direction, causing the slope of the L-shaped pressure plate 725 to separate from the conical surface of the pressure block 723. At this time, the pressure block 723 loses external pressure, and the return spring 713 releases its elastic potential energy, pushing the toggle block 714 back in the direction away from the sliding box 711. As the toggle block 714 moves, its toggle groove squeezes the toggle member 715, causing the toggle member 715 to rotate in the opposite direction around its axis and reset. This pushes the U-shaped section of the locking member 712 toward the inner wall of the arc slide rail 6, and eventually tightly fits against the inner wall of the slide rail, achieving locking through friction.

[0041] After locking, the camera body 5 forms a three-point support structure through the left and right hinge points and the locking piece 712. The straight-line distances between the three points are evenly distributed, forming an isosceles triangle, thereby significantly improving the overall rigidity of the hinge structure of the arc slide 6, locking mechanism, arc frame 3 and camera body 5. When the camera is impacted by external force, the load is dispersed along the triangular frame to the main rotating frame 2, the arc slide 6 and the arc frame 3, avoiding stress concentration on a single hinge point, and upgrading the linear force mode of the traditional single-axis hinge to a surface load distribution. The friction locking between the locking piece 712 and the inner wall of the arc slide 6 forms a double anti-deformation protection, which greatly improves the strength, stability and safety of the camera body 5 under the action of external force.

[0042] Finally, it should be noted that the above embodiments are merely examples for the purpose of illustrating the present invention and are not intended to limit the embodiments. Those skilled in the art will readily appreciate that other variations or modifications based on the above description are possible. It is not necessary and impossible to provide an exhaustive list of all embodiments. However, obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
