Description

Technical Field

[0001] The utility model relates to the technical field of camera anti-shake devices, and more specifically, to an anti-shake structure and an anti-shake camera. Background Art

[0002] At present, the concept of intelligent transportation has been continuously deepened, and the demand for video detection on highways is also increasing. If the coverage distance of the camera is short, a large number of cameras are required, increasing the cost. Therefore, it is necessary to increase the coverage distance of the camera. To increase the coverage distance of the camera, long-focus cameras are usually used and installed at a relatively high position (about six meters above the ground) for image acquisition. Theoretically, the longer the focal length of the camera (for example, a long-focus lens), the farther the coverage distance and the more concentrated the picture. Therefore, the prior art usually adopts this method to increase the coverage distance of the camera.

[0003] However, since the camera is usually installed at a relatively high position from the ground, the support frame for the camera is also high. In addition, the images captured by long-focus cameras are more sensitive to jitter, resulting in severe jitter in the video image when the camera is working and unstable detection targets. To reduce the above adverse effects, the prior art usually adopts methods such as installing a spring shock-absorbing structure on the whole camera, lens element anti-shake, algorithm anti-shake, increasing the rigidity of the frame, and expanding the detection range. Among them, the method of using lens element anti-shake will cause a sharp increase in the overall cost, the method of using algorithm anti-shake is difficult to implement, and the methods of increasing the rigidity of the frame and expanding the detection range have poor effects and poor practicability. Therefore, the method of installing a spring shock-absorbing structure on the whole camera is widely used, making the camera a camera with a certain anti-shake function.

[0004] In the prior art, there are some devices that install a spring shock-absorbing structure on the whole camera to achieve anti-shake of the camera. For example, CN212900439U discloses a high-stability anti-shake security monitoring camera, including an installation box. The bottom of the inner wall of the installation box is fixedly connected with a fixed box. The top of the fixed box and the installation box are both provided with a first through hole. A shell is arranged inside the fixed box. The top of the shell passes through the first through hole and extends to the outside of the installation box. A camera body is fixedly connected inside the shell. Card slots are arranged at the bottoms of both sides of the shell. The above technical solution uses a spring assembly to shock-absorb and anti-shake the whole camera, improving the stability of the camera (for example, the camera head). However, when the weight and size of the camera (lens) installed on the spring assembly change, the anti-shake requirements also need to be adjusted accordingly. However, the spring assembly of the above technical solution cannot be adjusted flexibly, so that the above technical solution cannot flexibly adapt to the anti-shake requirements of different cameras and has poor applicability. In addition, the above technical solution has a complex structure and the overall structure is relatively heavy, and cannot efficiently meet the use requirements of image acquisition work on the road.

Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0035] As Figures 1 to 4 shown, an embodiment of the present invention provides an anti-shake structure, including: a carrier structure 10, a carrier seat 20, a first balance member 30, and a second balance member 40; the carrier seat 20 is movably arranged on the carrier structure 10; the first balance member 30 includes a first adjusting member 31 and a first elastic member 32, and the second balance member 40 includes a second adjusting member 41 and a second elastic member 42.

[0036] In the present invention, by setting the elastic forces of the first elastic member 32 and the second elastic member 42 to be collinear and in opposite directions, the carrier seat 20 can be reliably balanced under the action of the elastic forces, and then when the carrier seat 20 shakes, it can be quickly stabilized, which is convenient for subsequent cooperation with the camera to realize a stable and continuous image acquisition function; by setting the distance between the second end of the first adjusting member 31 and the carrier seat 20 to be adjustable, and the distance between the second end of the second adjusting member 41 and the carrier seat 20 to be adjustable, the adjustment of the first elastic member 32 and the second elastic member 42 is realized, and then the flexible adjustment of the elastic force received by the carrier seat 20 and the subsequent elastic force change law is realized. When the carrier seat 20 cooperates with the camera to work subsequently, the flexible adaptation to different types of cameras is realized. Without replacing the first elastic member 32 and the second elastic member 42, the reliable anti-shake for different types of cameras is ensured, and the stability of image acquisition is improved; the structure of the present invention is simple, works reliably, has a low cost, and is relatively light in overall weight, which is suitable for large-scale popularization and use; in addition, the present invention is convenient for disassembly and installation. When damage occurs or maintenance is required, the staff can quickly disassemble and assemble it, saving the time and energy of the staff.

[0037] As Figure 4 shown, the bearing structure 10 has a first guiding hole 11 and a second guiding hole 12; the first end of the first adjusting member 31 passes through the first guiding hole 11 and is threadedly connected to one end of the bearing seat 20, and both ends of the first elastic member 32 are respectively in contact with the second end of the first adjusting member 31 and the inner wall of the first guiding hole 11; the first end of the second adjusting member 41 passes through the second guiding hole 12 and is threadedly connected to the other end of the bearing seat 20, and both ends of the second elastic member 42 are respectively in contact with the second end of the second adjusting member 41 and the inner wall of the second guiding hole 12.

[0038] By setting the threaded fit, the distance between the second end of the first adjusting member 31 and the inner wall of the first guiding hole 11 can be adjusted, and the distance between the second end of the second adjusting member 41 and the inner wall of the second guiding hole 12 can be adjusted, thereby realizing the adjustment of the first elastic member 32 and the second elastic member 42.

[0039] As Figure 3 and Figure 4 shown, the hole on the bearing seat 20 for threaded fit with the first adjusting member 31 is the first through threaded hole 21, and the hole on the bearing seat 20 for threaded fit with the second adjusting member 41 is the second through threaded hole 22; the bearing seat 20 has an observation cavity 23 inside, and the observation cavity 23 is respectively communicated with the first through threaded hole 21 and the second through threaded hole 22; wherein, by adjusting the length of the first adjusting member 31 screwed into the observation cavity 23, the distance between the second end of the first adjusting member 31 and the inner wall of the first guiding hole 11 is adjusted; by adjusting the length of the second adjusting member 41 screwed into the observation cavity 23, the distance between the second end of the second adjusting member 41 and the inner wall of the second guiding hole 12 is adjusted.

[0040] By setting the observation cavity 23, when adjusting the first adjusting member 31 and the second adjusting member 41, the threaded fit lengths between the first adjusting member 31 and the first through threaded hole 21 and between the second adjusting member 41 and the second through threaded hole 22 remain unchanged, thereby ensuring that the connection strength between the first adjusting member 31 and the second adjusting member 41 and the bearing seat 20 does not change due to adjustment, and improving the working reliability and stability of the bearing seat 20.

[0041] As Figure 3 and Figure 4 shown, the bearing seat 20 also has an observation window 24 for observation; the observation cavity 23 is communicated with the outside through the observation window 24, and has a first mark 25 and a second mark 26 for indicating positions on the inner wall respectively; when the first end of the first adjusting member 31 screwed into the observation cavity 23 corresponds to the first mark 25, and the first end of the second adjusting member 41 screwed into the observation cavity 23 corresponds to the second mark 26, the bearing seat 20 is in the set position.

[0042] By providing the observation window 24, it is convenient for the staff to observe and operate the first adjusting member 31 and the second adjusting member 41; by providing the first mark 25 and the second mark 26, the indication function of the set position is realized, thereby ensuring the accurate installation and adjustment of the carrier seat 20.

[0043] As Figure 3 and Figure 4 shown, the first mark 25 and the second mark 26 are one of a prompt line, a prompt groove or a prompt point; when the end face of the first end of the first adjusting member 31 is flush with the first mark 25 and the end face of the first end of the second adjusting member 41 is flush with the second mark 26, the carrier seat 20 is located at the set position.

[0044] This setting not only ensures the working reliability of the first mark 25 and the second mark 26, but also simplifies the first mark 25 and the second mark 26, making them easy to process and form.

[0045] As Figure 1 、 Figure 2 and Figure 3 shown, the bearing structure 10 includes a lower shell structure 13 and an upper shell structure 14. The lower shell structure 13 has an activity cavity 131 inside. The carrier seat 20 is movably arranged in the activity cavity 131 and is in limit guiding cooperation with the inner wall of the activity cavity 131; both sides of the lower shell structure 13 are respectively provided with a front opening window 132 and a rear opening window 133. Both sides of the activity cavity 131 are respectively communicated with the outside through the front opening window 132 and the rear opening window 133; wherein, the rear opening window 133 is communicated with the observation window 24 so that the observation cavity 23 is communicated with the outside; one side of the carrier seat 20 facing the front opening window 132 has a first positioning mark 27, and the part of the lower shell structure 13 located at the front opening window 132 has a second positioning mark 134. The first positioning mark 27 is used for corresponding cooperation with the second positioning mark 134 to position the carrier seat 20.

[0046] By providing the lower shell structure 13 and the upper shell structure 14, it is convenient for the quick disassembly and assembly between the bearing structure 10 and the carrier seat 20; by providing the first positioning mark 27 and the second positioning mark 134, accurate positioning of the carrier seat 20 relative to the bearing structure 10 is realized on the front side.

[0047] It should be noted that: as Figure 1 、 Figure 2 and Figure 4As shown, a partition plate 29 is further provided inside the carrier seat 20. The partition plate 29 divides the observation cavity 23 into two interconnected spaces, namely a first space and a second space. The first space faces the front opening window 132 and is directly connected to the front opening window 132; the second space faces the rear opening window 133, and the second space is directly connected to the rear opening window 133 through the observation window 24; by providing the partition plate 29, the subsequent carrier plate 60 can be detachably arranged on the plane of the partition plate 29 facing the first space.

[0048] In a specific embodiment of the present invention, as Figure 2 shown, there are a total of four groups of the first positioning marks 27 and the second positioning marks 134, which are arranged in a four-corner positioning manner. Among them, two groups corresponding to each other in the vertical direction simultaneously position the horizontal position of the carrier seat 20, and two groups corresponding to each other in the horizontal direction simultaneously position the vertical position of the carrier seat 20. The above vertical position can be set as the reset position of the carrier seat 20 after jitter.

[0049] As Figure 4 shown, the first guiding hole 11 includes a first accommodating section 111 and a first guiding section 112 that are sequentially connected; the first accommodating section 111 is used to accommodate the first elastic member 32, and both ends of the first elastic member 32 are respectively abutted against the second end of the first adjusting member 31 and the bottom wall of the first accommodating section 111; the inner wall of the first guiding section 112 is in limiting and guiding cooperation with the first adjusting member 31; and / or, the second guiding hole 12 includes a second accommodating section 121 and a second guiding section 122 that are sequentially connected; the second accommodating section 121 is used to accommodate the second elastic member 42, and both ends of the second elastic member 42 are respectively abutted against the second end of the second adjusting member 41 and the bottom wall of the second accommodating section 121; the inner wall of the second guiding section 122 is in limiting and guiding cooperation with the second adjusting member 41.

[0050] Such a setting not only simplifies the structure of the first guiding hole 11 and / or the second guiding hole 12, facilitating processing and forming, but also realizes reliable accommodation and restraint of the first elastic member 32 and / or the second elastic member 42.

[0051] As Figure 1 and Figure 4 shown, the first elastic member 32 and the second elastic member 42 have the same structure, both being spring structures; the first adjusting member 31 and the second adjusting member 41 have the same structure, both being bolt structures; the bolt structure includes a screw rod and a nut provided on the screw rod, and the nut is in abutting cooperation with the spring structure; the screw rod includes a light column section and a threaded section along the axial direction. One end of the light column section is fixedly connected to the nut, and the other end is fixedly connected to the threaded section. The spring structure is sleeved on the outer periphery of the light column section, and the threaded section has an external thread for threaded connection with the carrier seat 20.

[0052] By setting that the screw rod includes a light column section and a threaded section along the axial direction, the smoothness of elastic force transmission is ensured, and the overall structure is convenient for installation and unified replacement.

[0053] Optionally, the hole on the bearing seat 20 for threaded cooperation with the first adjusting member 31 is a first through threaded hole 21, and the hole on the bearing seat 20 for threaded cooperation with the second adjusting member 41 is a second through threaded hole 22; the threaded length of the first through threaded hole 21 along the axial direction and the threaded length of the second through threaded hole 22 along the axial direction are both greater than or equal to the threaded length of the threaded section along the axial direction; wherein, by adjusting the threaded cooperation length between the first adjusting member 31 and the first through threaded hole 21, the distance between the second end of the first adjusting member 31 and the inner wall of the first guiding hole 11 is adjusted; by adjusting the threaded cooperation length between the second adjusting member 41 and the second through threaded hole 22, the distance between the second end of the second adjusting member 41 and the inner wall of the second guiding hole 12 is adjusted.

[0054] By setting that the threaded length of the first through threaded hole 21 along the axial direction and the threaded length of the second through threaded hole 22 along the axial direction are both greater than or equal to the threaded length of the threaded section along the axial direction, the threaded cooperation lengths between the first adjusting member 31 and the first through threaded hole 21 and between the second adjusting member 41 and the second through threaded hole 22 can be adjusted. Compared with the above-mentioned way of observing the cavity 23 (i.e., the way with non-adjustable threaded cooperation length), the way with adjustable threaded length can adjust the connection strength between the first adjusting member 31 and the second adjusting member 41 and the bearing seat 20, and further provides structural support for the adaptation adjustment when different types of cameras are installed on the bearing seat 20 subsequently.

[0055] Such as Figure 1 and Figure 4 As shown, the first balancing member 30 further includes a first stop member 33, and the second balancing member 40 further includes a second stop member 43; the first stop member 33 is arranged on the first adjusting member 31 and is located between the first guiding hole 11 and the bearing seat 20 in the axial direction of the first adjusting member 31, and is used to restrict the reciprocating movement of the first adjusting member 31 along the axial direction; the second stop member 43 is arranged on the second adjusting member 41 and is located between the second guiding hole 12 and the bearing seat 20 in the axial direction of the second adjusting member 41, and is used to restrict the reciprocating movement of the second adjusting member 41 along the axial direction.

[0056] By setting the first stop member 33 and the second stop member 43, the reliable restriction on the shaking amplitude of the bearing seat 20 is ensured.

[0057] In a specific embodiment of the present invention, both the first stop member 33 and the second stop member 43 are in the form of snap rings, which are convenient for procurement and installation and ensure the reliable limit on the bearing seat 20.

[0058] Such as Figure 1 and Figure 4As shown, the bearing structure 10 includes a lower housing structure 13 and an upper housing structure 14. An active cavity 131 is provided inside the lower housing structure 13. The bearing seat 20 is movably arranged in the active cavity 131 and is in limit guiding cooperation with the inner wall of the active cavity 131. The first guiding hole 11 is located on the upper housing structure 14, and the second guiding hole 12 is located on the lower housing structure 13. The upper housing structure 14 is detachably arranged on the lower housing structure 13.

[0059] This setting facilitates the quick disassembly and assembly between the bearing structure 10 and the bearing seat 20.

[0060] As Figure 4 As shown, the lower housing structure 13 and the upper housing structure 14 respectively have protruding parts 15. Both ends of the bearing seat 20 respectively have fitting grooves 28. The fitting groove 28 at one end is in limit guiding cooperation with the protruding part 15 of the lower housing structure 13, and the fitting groove 28 at the other end is in limit guiding cooperation with the protruding part 15 of the upper housing structure 14. The first guiding hole 11 is located on the protruding part 15 of the upper housing structure 14, and the second guiding hole 12 is located on the protruding part 15 of the lower housing structure 13. The first balancing member 30 further includes a first stop member 33, and the second balancing member 40 further includes a second stop member 43. The first stop member 33 is located in the fitting groove 28 that cooperates with the protruding part 15 of the upper housing structure 14 and is in limit cooperation with the protruding part 15 of the upper housing structure 14. The second stop member 43 is located in the fitting groove 28 that cooperates with the protruding part 15 of the lower housing structure 13 and is in limit cooperation with the protruding part 15 of the lower housing structure 13.

[0061] By setting the fitting groove 28 in limit guiding cooperation with the protruding part 15, the constraint strength for the bearing seat 20 is further ensured, and thus the stability of the bearing seat 20 is ensured.

[0062] Optionally, the central axes of the first adjusting member 31 and the first elastic member 32 are collinear and extend along the vertical direction. The central axes of the second adjusting member 41 and the second elastic member 42 are collinear and extend along the vertical direction. There are multiple first balancing members 30 and multiple first guiding holes 11. The multiple first guiding holes 11 are arranged at intervals in the horizontal direction, and the multiple first guiding holes 11 are in one-to-one correspondence and cooperation with the multiple first balancing members 30. There are multiple second balancing members 40 and multiple second guiding holes 12. The multiple second guiding holes 12 are arranged at intervals in the horizontal direction, and the multiple second guiding holes 12 are in one-to-one correspondence and cooperation with the multiple second balancing members 40.

[0063] By setting the central axes of the first adjusting member 31 and the first elastic member 32 to be collinear and the central axes of the second adjusting member 41 and the second elastic member 42 to be collinear, reliable shock absorption of the bearing seat 20 in the vertical direction is ensured, effectively preventing large-amplitude and long-time jitter of the bearing seat 20 in the vertical direction.

[0064] The utility model also provides an anti-shake camera, which includes the above-mentioned anti-shake structure; the anti-shake camera also includes a camera module 50 and a carrier plate 60, the camera module 50 is detachably arranged on the carrier plate 60 for collecting image data; the carrier plate 60 is detachably arranged on the carrier seat 20.

[0065] It should be noted that: the camera module 50 has a compact structure, can be transported and installed in a modular manner, and has high versatility; when the camera module 50 shakes violently, the support seat 20 slides in the lower shell structure 13, and damping and shock absorption are formed through spring compression, which reduces the shaking of the camera module 50 when capturing scene images to a certain extent; when the camera module 50 (such as the lens) needs to be replaced, due to the change in weight, the set position of the support seat 20 (for example: the initial locking position) and the compression amount of the spring (that is, the spring structure) need to be adjusted. At this time, by adjusting the first adjusting member 31 and the second adjusting member 41, the spring compression amount can be adjusted, and the size of the spring pre-compression force can be changed, so as to adapt to different camera modules 50 and ensure the stability of capturing.

[0066] like Figure 1 As shown, the bearing structure 10 includes a lower shell structure 13 and an upper shell structure 14, the lower shell structure 13 has an active cavity 131 inside, the bearing seat 20 can be movably arranged in the active cavity 131, and cooperates with the inner wall limit guide of the active cavity 131; the two sides of the lower shell structure 13 are respectively provided with a front window 132 and a rear window 133, the two sides of the active cavity 131 are connected to the outside through the front window 132 and the rear window 133 respectively; wherein, the part of the bearing plate 60 passing through the front window 132 is detachably connected to the bearing seat 20, at least a part of the bearing plate 60 is located in the front window 132, and cooperates with the inner wall limit of the front window 132 to constrain the movement range of the bearing plate 60; the wire used for electrically connecting to the camera module 50 extends from the rear window 133 to be electrically connected to an external device.

[0067] By providing a portion of the carrier plate 60 that passes through the front opening window 132 and is detachably connected to the carrier seat 20, it is convenient for quick installation of the carrier plate 60 and the camera module 50 and the movement range of the carrier plate 60 is reliably constrained; by providing a rear opening window 133, circuit routing is facilitated.

[0068] Now the specific working process and principle of the utility model are described in detail as follows:

[0069] The existing technical solution is to rigidly connect the camera module 50 to the frame. When the camera module 50 and the frame shake violently, the scene captured by the camera also shakes violently, which is not conducive to the stable and accurate collection of image information. The utility model avoids the rigid connection method and sets the support seat 20 to slide in the lower shell structure 13. The damping shock absorption is formed by spring compression, which avoids the violent shaking of the camera module 50 and reduces the shaking of the camera captured scene to a certain extent. When the camera module 50 (such as the lens) needs to be replaced, due to the change in weight, the set position of the support seat 20 (for example: the initial locking position) and the compression amount of the spring (that is, the spring structure) need to be adjusted. At this time, by adjusting the first adjusting member 31 and the second adjusting member 41, the spring compression amount can be adjusted, and the size of the spring pre-compression force can be changed, so as to adapt to different camera modules 50 and ensure the stability of capturing.

[0070] In summary, the utility model provides an anti-shake structure and an anti-shake camera. The utility model sets the elastic force of the first elastic member 32 and the elastic force of the second elastic member 42 in the same line and in the opposite direction, so that the support seat 20 can be reliably balanced under the action of the elastic force, and then when the support seat 20 shakes, it can be quickly stabilized, which is convenient for subsequent cooperation with the camera to achieve a stable and continuous image acquisition function; by setting the distance between the second end of the first adjusting member 31 and the support seat 20 to be adjustable, and the distance between the second end of the second adjusting member 41 and the support seat 20 to be adjustable, the adjustment of the first elastic member 32 and the second elastic member 42 is achieved. , thereby realizing flexible adjustment of the elastic force exerted on the supporting seat 20 and the subsequent elastic force change law. When the supporting seat 20 works with the camera in the subsequent process, flexible adaptation to different types of cameras is realized. Without replacing the first elastic member 32 and the second elastic member 42, reliable anti-shake for different types of cameras is guaranteed, and the stability of image acquisition is improved. The utility model has a simple structure and reliable operation, low cost, and light overall weight, and is suitable for large-scale promotion and use. In addition, the utility model is easy to disassemble and install. When damage occurs or maintenance is required, the staff can quickly disassemble and assemble it, saving the staff's time and energy.
