A driving recorder with an anti-shake structure

Abstract

The present invention discloses a driving recorder with an anti-shake structure, belonging to the technical field of driving recorders, including an adsorption device, and a connecting cylinder is connected to the bottom of the adsorption device, and an adjustment component is arranged in the connecting cylinder. In the present invention, by setting an anti-shake component, when on a flat road surface, the damping spring is contracted to increase its stiffness threshold, avoiding deformation triggered by minute vibrations and maintaining the stability of the camera body. When on an off-road section, the damping spring is extended to reduce the stiffness threshold, making it more sensitive to large vibrations on rough road surfaces and enhancing the energy absorption efficiency, so that the anti-shake component can be applicable to different road surfaces, improving its applicability and flexibility. Moreover, the damping characteristics of the buffer medium effectively absorb the high-frequency vibration energy generated by the damping spring, and cooperate with the linear energy absorption of the damping spring to form a "spring + fluid" two-stage vibration damping, reducing the resonance amplitude of the camera body, thereby improving the overall stability of the camera body and ensuring the clarity and stability of the captured image.

Description

Technical Field

[0001] The present invention belongs to the technical field of driving recorders, and particularly relates to a driving recorder with an anti-shake structure. Background Art

[0002] A driving recorder is an instrument that records images, sounds and other relevant information during vehicle driving. After installing a driving recorder, it can record video images and sounds of the whole process of vehicle driving, provide evidence for traffic accidents, and facilitate traffic police and vehicle owners to understand the accident situation in time.

[0003] The document with the publication number of CN119399854A discloses a driving recorder. The automatic adjustment lens structure allows the driving recorder to make real-time adjustments according to different lighting and environmental conditions, and can provide the optimal viewing angle setting in various driving scenarios; the design structure of the camera module avoids the common high distortion phenomenon in traditional lenses; by reasonably configuring the shape and refractive index of the lens, the geometric integrity of the image can be maintained at a large viewing angle, so that the photographed scenery and objects are not distorted. At the same time, the non-glued design is adopted to avoid the performance degradation caused by environmental changes (such as temperature and humidity), and the lens can still maintain stable optical performance and image quality under different usage conditions, solving the problems of aging and optical degradation that may occur in glued lenses during long-term use. However, in the actual use process, common driving recorders are difficult to adjust their anti-shake performance well when facing different road conditions, resulting in unclear and unstable captured images. Therefore, improvements are needed. Summary of the Invention

[0026] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0027] 1. In the present invention, by setting an anti-shake assembly, when the camera body operates normally, the transmission gear cooperates with the positive and negative lead screws and the lead screw seat to separate the limit rod and the adapter rod from each other, so that the limit rod no longer limits the connecting cross plate. When not in use, the limit rod limits the adapter rod, so that the entire anti-shake assembly is in a non-operating state, so that various parts of the anti-shake assembly are in a static state, reducing the mechanical wear of various parts and increasing the overall service life. At the same time, the contraction amount of the damping spring is adjusted by the sliding sleeve to change its initial preload and effective stroke. When the road surface is leveled, the damping spring is contracted to increase its The stiffness threshold is used to avoid deformation triggered by tiny vibrations and maintain the stability of the camera subject. When driving on off-road sections, the vibration-damping spring is extended to reduce the stiffness threshold, making it more sensitive to large vibrations on rugged roads and enhancing energy absorption efficiency. This allows the anti-shake component to be suitable for different roads, improving its applicability and flexibility. In addition, the damping characteristics of the buffer medium effectively absorb the high-frequency vibration energy generated by the vibration-damping spring, and cooperate with the linear energy absorption of the vibration-damping spring to form a "spring + fluid" two-stage vibration reduction, reducing the resonance amplitude of the camera subject, thereby improving the overall stability of the camera subject and ensuring the clarity and stability of the captured image.

[0028] 2. In the present invention, by setting an adjustment component, the fixed motor drives the adjustment connecting seat to tilt to one side through the rotating plate, the extrusion block, the extrusion wheel, the sliding rod, the return spring, the connecting rod and the two universal shaft seats. At the same time, the remaining connecting rods cooperate with the universal shaft seat, the sliding rod and the return spring to drive the adaptive displacement of the adjustment connecting seat, thereby completing the adjustment of the angular orientation of the adjustment connecting seat, so that the adjustment connecting seat can drive the camera subject to change the angle, so that the camera subject can be suitable for different types of vehicles, thereby improving the overall applicability of the device, and the use of multiple universal shaft seats can avoid interference when the adjustment connecting seat is deflected, and cooperate with the setting of multiple connecting rods and sliding rods to increase the number of degrees of freedom of the adjustment connecting seat, which is more conducive to the accuracy of angle adjustment.

[0029] 3. In the present invention, by setting a shielding component, the driving motor drives the shielding plate to rotate through the driving gear, the outer gear ring, the rotating disk, the hinge seat and the connecting rod, so that the circular groove and the through groove are opened, so that the lens of the camera body is exposed, so that the camera body can operate normally, and the automatic exposure and shielding of the camera body is realized through the transmission of the mechanical mechanism, ensuring that the lens is effectively protected in the non-working state, and can effectively prevent dust and impurities from contaminating the lens, thereby extending the service life of the equipment.

An adjustment assembly 8 is arranged inside the connecting cylinder 2. A connecting cross plate 3 is connected to the bottom of the adjustment assembly 8. A camera main body 5 is arranged at the bottom of the connecting cross plate 3 through an anti-shake assembly 4. A shielding assembly 6 is arranged on one side of the camera main body 5. A driving assembly 7 for driving the shielding assembly 6 is arranged at the bottom of the camera main body 5;

[0046] The anti-shake component 4 includes two symmetrically arranged outer sleeves 416. A buffer medium is arranged inside the outer sleeve 416. A piston plate 415 is slidably connected inside the outer sleeve 416. A plurality of flow holes 414 distributed in a circumferential array are formed on the piston plate 415. A piston rod 413 is connected to the bottom of the piston plate 415. One end of the piston rod 413 extends outside the outer sleeve 416 and is connected to the top of the camera body 5. A damping spring 407 is sleeved on the outer peripheral side of the outer sleeve 416. A sliding connecting sleeve 403 for adjusting the elastic force of the damping spring 407 is arranged at the top of the damping spring 407. The buffer medium buffers the piston plate 415 when it moves, reducing the jitter when the damping spring 407 is compressed or stretched. The sliding connecting sleeve 403 is slidably connected to the outer walls of the two outer sleeves 416. Both sides of the damping spring 407 are connected to the bottom of the sliding connecting sleeve 403 and the top of the camera body 5 respectively. A adjusting lead screw 406 is drivingly connected to the central position of the sliding connecting sleeve 403. The top of the adjusting lead screw 406 is rotatably connected to the bottom of the connecting cross plate 3. A second bevel gear 409 is connected to the outer surface of the adjusting lead screw 406. A first bevel gear 408 is meshed and connected to one side of the second bevel gear 409. A rotating rod is connected to one side of the first bevel gear 408. A rotating member is rotatably connected to the outer surface of the rotating rod. The rotating member is connected to the bottom of the connecting cross plate 3. A knob is connected to the end of the rotating rod away from the first bevel gear 408. Mounting seats are connected to both sides of the top of the camera body 5. A forward and reverse lead screw 411 is rotatably connected between the two mounting seats. The forward and reverse lead screw 411 is symmetrically arranged along its central position. The thread directions on both sides of the forward and reverse lead screw 411 are opposite. Two symmetrically arranged lead screw seats 412 are drivingly connected to the outer surface of the forward and reverse lead screw 411. The bottom of the lead screw seat 412 is in contact with the top of the camera body 5. Limit rods 402 are connected to both sides of the top of the lead screw seat 412. An adapter rod 410 is arranged above the limit rod 402. One side of the adapter rod 410 is connected to one side of the connecting cross plate 3. The limit rod 402 can contact the adapter rod 410 during the movement. One end of the forward and reverse lead screw 411 extends to the other side of the mounting seat and is connected to a transmission gear 401. Two symmetrically arranged fixed slide rods 404 are connected to the bottom of the connecting cross plate 3. The fixed slide rods 404 are slidably connected to the sliding connecting sleeve 403. The same fixed bottom plate 405 is connected to the ends of the two fixed slide rods 404 away from the connecting cross plate 3. The end of the forward and reverse lead screw 411 away from the connecting cross plate 3 is rotatably connected to the top of the fixed bottom plate 405.

[0047] The implementation manner is specifically as follows: By setting the anti-shake component 4, when the camera main body 5 is operating normally, the driving gear 401 cooperates with the forward and reverse lead screw 411 and the lead screw seat 412 to separate the limit rod 402 from the adapter rod 410, so that the limit rod 402 no longer limits the connecting cross plate 3. In the non-use state, the limit rod 402 limits the adapter rod 410, making the entire anti-shake component 4 in a non-operating state, so that its various parts are in a static state, reducing the mechanical wear of each part and improving its overall service life. At the same time, by adjusting the contraction amount of the damping spring 407 through the sliding connecting sleeve 403, its initial pre-tightening force and effective stroke are changed. When on a flat road surface, the damping spring 407 is contracted to increase its stiffness threshold to avoid deformation triggered by tiny vibrations and maintain the stability of the camera main body 5. When on an off-road section, the damping spring 407 is extended to lower the stiffness threshold, making it more sensitive to the large vibrations of the rough road surface and enhancing the energy absorption efficiency, so that the anti-shake component 4 can be applicable to different road surfaces, improving its applicability and flexibility. Moreover, the damping characteristics of the buffer medium effectively absorb the high-frequency vibration energy generated by the damping spring 407, and cooperate with the linear energy absorption of the damping spring 407 to form a "spring + fluid" two-stage damping, reducing the resonance amplitude of the camera main body 5, thereby improving the overall stability of the camera main body 5 and ensuring the clarity and stability of the captured image. The buffer medium is hydraulic oil.

[0048] The adjustment component 8 includes an orientation-adjusting connecting seat 801 connected to the top of the connecting cross plate 3. A plurality of linkage rods 802 distributed in a circumferential array are arranged on the top of the orientation-adjusting connecting seat 801. Universal shaft seats 810 are connected to both the upper and lower ends of the linkage rod 802. The universal shaft seat 810 at the bottom is connected to the top of the orientation-adjusting connecting seat 801, and the universal shaft seat 810 at the top is connected to a sliding rod 809 at the top. The other end of the sliding rod 809 is connected to an extrusion wheel 807 for orientation adjustment. A rotating plate 805 that rotates relatively is arranged above the extrusion wheel 807, and there is a gap between the extrusion wheel 807 and the rotating plate 805. One side of the bottom of the rotating plate 805 is connected to an extrusion block 803. The cross-sectional shape of the extrusion block 803 is trapezoidal, and the extrusion block 803 can drive one of the extrusion wheels 807 to move during rotation. A plurality of connecting frames 804 distributed in a circumferential array are connected to the inner wall of the connecting cylinder 2. The connecting frames 804 are slidably connected to the sliding rod 809. A return spring 808 is sleeved on the outer surface of the sliding rod 809. Both ends of the return spring 808 are respectively connected to one side of the connecting frame 804 and one side of the extrusion wheel 807. A fixed motor 806 is connected to the inside of the connecting cylinder 2 through a second mounting frame. One end of the output shaft of the fixed motor 806 is connected to the rotating plate 805.

[0049] The implementation method is specifically as follows: By setting the adjustment component 8, the fixed motor 806 drives the steering connection seat 801 to tilt to one side through the rotating plate 805, the extrusion block 803, the extrusion wheel 807, the sliding rod 809, the return spring 808, the linkage rod 802 and the two universal shaft seats 810. At the same time, the remaining linkage rods 802 cooperate with the universal shaft seats 810, the sliding rod 809 and the return spring 808 to drive the steering connection seat 801 to adaptively offset, thereby completing the adjustment of the angular orientation of the steering connection seat 801, enabling the steering connection seat 801 to drive the camera main body 5 to change the angle, so that the camera main body 5 can be applicable to different types of vehicles, thus improving the overall applicability of the device. And the application of multiple universal shaft seats 810 can avoid interference when the steering connection seat 801 deflects. With the setting of multiple linkage rods 802 and the sliding rod 809, the number of degrees of freedom of movement of the steering connection seat 801 is increased, which is more conducive to the accuracy of angle adjustment. And the fixed motor 806 is a self-locking motor. When it stops rotating, it can automatically lock the output shaft to prevent the rotating plate 805 from rotating back.

[0050] The shielding component 6 includes a fixed disk 605. A through groove is provided on one side of the fixed disk 605. A fixed shaft is connected to one side of the fixed disk 605 and is distributed in a circumferential array. A shielding plate 604 for shielding the through groove is rotatably connected to the outer surface of the fixed shaft. One side of the top of the shielding plate 604 is hinged with a connecting rod 603. A rotating disk 601 is rotatably connected to the top of the fixed disk 605. A plurality of hinge seats are connected to the inner side of the rotating disk 601 and are distributed in a circumferential array. One end of the hinge seat is hinged with the end of the connecting rod 603 away from the shielding plate 604. The fixed disk 605 is connected to one side of the camera main body 5. A circular groove is provided on one side of the rotating disk 601, and the diameter of the circular groove is the same as that of the through groove. An external tooth ring 602 is connected to the outer peripheral side of the rotating disk 601, and the external tooth ring 602 is engaged with the transmission gear 401. And when the plurality of shielding plates 604 are mutually attached, they can form a complete closed circle.

[0051] The driving component 7 includes a driving motor 702. The driving motor 702 is fixedly installed at the bottom of the camera main body 5 through a first mounting bracket. One end of the output shaft of the driving motor 702 is connected with a driving gear 701, and the driving gear 701 is engaged and connected with the external tooth ring 602.

[0052] The implementation method is specifically as follows: By setting the shielding component 6, the driving motor 702 drives the shielding plate 604 to rotate through the driving gear 701, the external tooth ring 602, the rotating disk 601, the hinge seat and the connecting rod 603, so that the circular groove and the through groove are opened, the lens of the camera main body 5 is exposed, and the camera main body 5 can operate normally. The automatic exposure and shielding of the camera main body 5 are realized through the transmission of the mechanical mechanism, ensuring that the lens is effectively protected in the non-working state, effectively preventing dust and impurities from contaminating the lens, prolonging the service life of the device, and the driving motor 702 is a self-locking motor. When it stops rotating, it can automatically lock the output shaft to avoid the rotation plate 805 from rotating back.

[0053] Working principle: During use, the staff uses the adsorption device 1 to adsorb and connect the camera main body 5 to the front windshield of the car, thus completing the fixed installation of the camera main body 5. After that, the staff starts the fixed motor 806. The fixed motor 806 drives the rotating plate 805 to rotate. The rotating plate 805 drives the extrusion block 803 to rotate. The extrusion block 803 drives one of the extrusion wheels 807 distributed in a circumferential array to move. The extrusion wheel 807 drives the sliding rod 809 to move downward. At this time, the return spring 808 contracts. The sliding rod 809 drives the two universal shaft seats 810 through the connecting rod 802 to drive the steering connection seat 801 to tilt to one side. And at this time, the remaining connecting rods 802 cooperate with the universal shaft seats 810, the sliding rods 809 and the return spring 808 to drive the steering connection seat 801 to adaptively shift, thus completing the adjustment of the angular orientation of the steering connection seat 801, so that the steering connection seat 801 can drive the camera main body 5 to change the angle, so that the camera main body 5 can be applicable to different types of vehicles.

[0054] After the installation of the camera main body 5 is completed, when the staff drives the vehicle and needs to use the driving recorder, the driving motor 702 drives the driving gear 701 to rotate. The driving gear 701 drives the external tooth ring 602 to rotate. The external tooth ring 602 drives the rotating disk 601 to rotate. The rotating disk 601 drives the hinge seat to rotate. The hinge seat drives the connecting rod 603 to rotate. The connecting rod 603 drives the shielding plate 604 to rotate around the fixed shaft, so that the circular groove and the through groove are opened, the lens of the camera main body 5 is exposed, and the camera main body 5 can operate normally.

[0055] During the opening process of the baffle 604, the driving motor 702 drives the outer tooth ring 602 to rotate through the driving gear 701. The outer tooth ring 602 drives the transmission gear 401 to rotate, the transmission gear 401 drives the positive and negative lead screw 411 to rotate, the positive and negative lead screw 411 drives two relatively arranged lead screw seats 412 to move away from each other, and the lead screw seat 412 drives the limiting rod 402 to move outward, so that the limiting rod 402 is separated from the matching rod 410, and the limiting rod 402 no longer limits the connecting cross plate 3, enabling the anti-shake assembly 4 to operate normally. Moreover, the staff can adjust the contraction amount of the damping spring 407 according to different road conditions. The staff drives the rotating rod to rotate through the knob, the rotating rod drives the first bevel gear 408 to rotate, the first bevel gear 408 drives the second bevel gear 409 to rotate, the second bevel gear 409 drives the adjusting lead screw 406 to rotate, the adjusting lead screw 406 drives the sliding connecting sleeve 403 to move, and the sliding connecting sleeve 403 drives the damping spring 407 to contract or extend, thereby changing the kinetic energy absorption ability of the damping spring 407. When facing a flat road surface, the damping spring 407 is contracted, so that the energy absorption critical value of the damping spring 407 becomes higher, and minor bumps will not affect the overall stability of the imaging body 5. When on an off-road section, the length of the damping spring 407 itself becomes longer, so that the energy absorption critical value of the damping spring 407 becomes lower, and it can more sensitively face rough road conditions. At the same time, through the buffer medium stored in the outer sleeve 416, when the piston plate 415 slides in the outer sleeve 416, the buffer medium passes through the flow hole 414, which will buffer and slow down the movement of the piston plate 415, thereby reducing the influence of the reset of the damping spring 407 on the piston rod 413 and improving the smoothness of the damping spring 407 during energy absorption, thereby improving the anti-shake performance of the imaging body 5.

[0056] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
