TECHNICAL FIELD
[0001] The utility model relates to a support technical field, especially a bidirectional rotation support. BACKGROUND
[0002] With the popularization of intelligent devices and security monitoring systems, cameras and other electronic devices requiring directional observation are increasingly widely applied in industrial automation, smart home, unmanned driving and public safety fields. In order to meet the requirements of high-definition image acquisition and accurate angle adjustment in different scenes, higher requirements are put forward for the flexibility, stability and compactness of the supporting structure. The common camera supports on the market mostly adopt simple fixed or single-axis rotating structures, mainly relying on gears, motors or manual adjustment to complete the rotation in the horizontal or vertical direction.
[0003] However, the single-axis rotating support can only rotate in one direction within 360° or 90° in the same plane, and cannot meet the combined requirements of large-range horizontal rotation and small-amplitude pitching adjustment, resulting in insufficient flexibility of angle adjustment. In order to achieve high-precision positioning, most electric rotating tables or gear-driven structures need to occupy a large installation space and are equipped with external motors and drivers, which significantly increases the overall size and weight, which is not conducive to lightweight and compact design. The gear meshing and motor reduction mechanism is prone to gap and wear during long-term use, causing increased backlash, inaccurate positioning, and the need for regular maintenance or replacement of parts. The electric support needs wiring, power distribution and control system, and the manual support needs multiple locking nuts or knobs, which makes the installation process cumbersome and inconvenient for on-site adjustment, and the maintenance cost is high.
[0004] Therefore, there is an urgent need for a compact, easy-to-install, externally-driven support device that simultaneously has large-range rotation and small-amplitude oscillation functions to meet the requirements of high-precision, low-cost and high-reliability in multiple scenarios. The support device should have mechanical limiting and self-locking functions to achieve accurate positioning and angle switching without additional control systems, and to maintain a low overall thickness in limited space.

[0025] The technical solution provided by this utility model is further illustrated below with reference to the embodiments.
[0026] like Figure 1 As shown, this embodiment provides a bidirectional rotating bracket. The bidirectional rotating bracket 100 includes a fixing assembly, a guide rail bracket assembly, and a rotating plate 2; wherein,
[0027] The rotating plate 2 and the fixed assembly are rotatably connected, so that the rotating plate 2 rotates in the plane where it is located;
[0028] The guide rail support assembly is provided with an arc-shaped groove 31; the fixed assembly is slidably connected with the guide rail support assembly through the arc-shaped groove 31, so that the fixed assembly slides along the track of the arc-shaped groove 31, thereby driving the rotating plate 2 to swing.
[0029] As shown in FIG. 3(b), the fixed assembly includes a fixed frame 1, which is provided with a fixed frame bottom plate 11, and opposite sides of the fixed frame bottom plate 11 are respectively provided with fixed frame side plates 12 fixedly connected with the fixed frame bottom plate 11; the fixed frame bottom plate 11 is parallel to the plane where the rotating plate 2 is located; and the fixed frame side plates 12 are perpendicular to the fixed frame bottom plate 11.
[0030] The guide rail support assembly includes a first guide rail support 3 and a second guide rail support 4 which are mirror-symmetrically arranged; the first guide rail support 3 and the second guide rail support 4 both have guide rail support plates 32, and the guide rail support plates 32 of the first guide rail support 3 and the second guide rail support 4 are respectively close to different fixed frame side plates 12; and the arc-shaped groove 31 is arranged on the guide rail support plates 32.
[0031] As Figure 2 , FIG. 3(a) and FIG. 3(b) show that the fixed frame side plates 12 are provided with through holes, and the middle part of the first fastener 6 extends through the through holes of the fixed frame side plates 12 and the arc-shaped groove 31 of the guide rail support plates 32; the two ends of the first fastener 6 are respectively abutted against the fixed frame side plates 12 and the guide rail support plates 32, so as to press the fixed frame side plates 12 and the guide rail support plates 32 together, and drive the fixed frame to slide along the track of the arc-shaped groove 31 through the middle part of the first fastener 6, thereby driving the rotating plate 2 to swing. As Figure 2 shown, preferably, the first arc A of the arc-shaped groove 31 is 17 degrees. FIG. 3(a) is a schematic view of the fixed frame 1 located at the first end of the arc-shaped groove 31, and FIG. 3(b) is a schematic view of the fixed frame 1 located at the second end of the arc-shaped groove 31. The fixed frame 1 can slide along the arc-shaped groove 31 between the first end of the arc-shaped groove 31 and the second end of the arc-shaped groove 31. The mirror-symmetric first guide rail support 3 and the second guide rail support 4 form a rigid slide rail through the guide rail support plates 32 and guide rail support fixed plates 33, and cooperate with the through holes on the fixed frame side plates 12 and the first fastener 6 to ensure smooth sliding and improve the strength and durability of the overall structure in the pressed state.
[0032] In this embodiment, the first fastener 6 is exemplified by a press-in rivet, which can reduce the required installation space and reduce the overall size of the equipment. However, in other embodiments, combinations of nuts and bolts can also be used.
[0033] AsFigure 1 As shown, the middle part of the first fastener 6, between the end of the first fastener 6 and the guide rail bracket plate 32, is also fitted with a first elastic element 61 to increase the tightness. Taking the press-fit stud as an example, the first fastener 6, in conjunction with the first elastic element 61, can reduce the space required for installation and reduce the thickness of the bracket, while also increasing the preload through the elastic element to prevent loosening.
[0034] As shown in Figure 3(b), the first guide rail bracket 3 and the second guide rail bracket 4 are respectively provided with guide rail bracket fixing plates 33; the guide rail bracket fixing plates 33 are perpendicular to the guide rail bracket plates 32 and are fixedly connected; the guide rail bracket fixing plates 33 are provided with mounting holes and positioning holes.
[0035] As shown in Figures 4(a) and 4(b), the rotating plate 2 is provided with an arc-shaped limiting groove 21, and the fixing component is provided with a limiting rib 51. The limiting rib 51 extends into the arc-shaped limiting groove 21, thereby limiting the rotation angle of the rotating plate 2. As shown in Figure 4(a), preferably, the second angle B of the arc-shaped limiting groove 21 is 90 degrees. By means of the engagement between the arc-shaped limiting groove 21 on the rotating plate 2 and the limiting rib 51 on the fixing component, the mechanical limiting of the rotation angle (preferably 90°) is achieved, without the need for additional electronic or pneumatic devices, and the repeatability and reliability of positioning can be guaranteed.
[0036] The rotating plate 2 is provided with mounting holes and positioning holes for mounting the equipment to be rotated. As shown in Figures 4(a) and 4(b), the positions of the first guide rail bracket 3 and the second guide rail bracket 4 are fixed. The rotating plate 2 can drive the equipment to be rotated (not shown in the figure) to rotate 90 degrees. The rotating plate 2 can rotate freely in its own plane, and at the same time, it is slidably connected to the guide rail bracket assembly through the arc groove 31, so that the rotating plate 2 can swing along the arc trajectory. It can rotate in a wide range of 0-90° in its own plane, and can also swing in a small range of 17° with the arc groove 31, so as to cover a wider field of view and make the adjustment more flexible.
[0037] Specifically, such as Figure 1 As shown, the fixing assembly also includes: a second fastener 7 and a limiting member 5; wherein, the fixing frame base plate 11, the limiting member 5 and the rotating plate 2 of the fixing frame 1 are pressed together by the second fastener 7; wherein, the limiting member 5 and the fixing frame base plate 11 remain relatively stationary; the rotating plate 2 is rotatably connected to the fixing frame base plate 11; the limiting rib 51 is provided on the side of the limiting member 5 near the rotating plate 2.
[0038] Specifically, such as Figure 1As shown, the two ends of the second fastener 7 abut against the base plate 11 of the fixing frame and the limiting member 5, respectively, and the middle part of the second fastener 7 is a non-circular column; the base plate 11 of the fixing frame and the limiting member 5 are provided with through holes that match the cross-sectional shape of the middle part of the second fastener 7; the rotating plate 2 is provided with through holes that allow the middle part of the second fastener 7 to rotate freely. This embodiment uses a press-fit stud as an example to illustrate the second fastener 7. Press-fit studs can reduce the required installation space and reduce the overall size of the equipment. However, in other embodiments, a combination of nuts and studs can also be used.
[0039] Preferably, such as Figure 1 As shown, the fixing assembly also includes: a gasket 10, a first flat washer 81, a second flat washer 82, and a second elastic element 9; wherein, the thickness of the gasket 10 can be selected according to the required thickness of the bidirectional rotating bracket 100. That is, by adding gaskets 10 of different thicknesses between the fixing bracket base plate 11 and the limiting member 5, the total thickness of the bracket can be flexibly adjusted according to the subsequent equipment installation requirements, greatly improving the adaptability and customizability of the product. The first flat washer 81 and the second flat washer 82 are respectively disposed on both sides of the rotating plate 2; used to improve the rotational smoothness of the rotating plate 2; the second elastic element 9 is disposed between the end of the second fastener 7 near the rotating plate 2 and the rotating plate 2, used to improve the tightness. In this embodiment, preferably, the second elastic element 9 is a butterfly spring. The flat washer (first flat washer 7 and second flat washer 8) and the butterfly spring 9 (second elastic element) are disposed on both sides of the rotating plate 2, which can effectively reduce friction, improve the rebound force, make the rotation smoother, and extend the service life.
