Description

Technical Field

[0001] The invention belongs to the technical field of digital hard disk video recorders, and in particular relates to a digital hard disk video recorder with a shock reduction and stabilization function and a shock reduction method thereof. Background Art

[0002] A digital video recorder (DVR) is a surveillance device that stores digital video signals on a hard drive and is widely used in security surveillance systems. Unlike traditional analog recorders, a DVR converts video signals captured by cameras into digital signals, storing them on a hard drive for long-term storage and playback. It supports multi-channel video input, allowing it to simultaneously receive video signals from multiple cameras. It uses compression technologies (such as H.264) to reduce storage space requirements, thereby improving storage efficiency. DVRs typically offer real-time monitoring, recording, playback, and remote access capabilities. Users can access and control the device via a local area network or the internet, enabling remote management.

[0003] Since the interior of a digital video recorder is relatively delicate, a buffering and shock-absorbing device is usually installed to assist in the buffering process in order to prevent it from being damaged. However, the installation between a conventional buffering device and a digital video recorder is relatively cumbersome, and quick assembly between the recorder and the device cannot be achieved. At the same time, the entire buffering device needs to be fixed in multiple places to achieve the buffering and shock-absorbing process, which is relatively cumbersome to use.

[0004] Moreover, the entire video recorder will vibrate in multiple directions when it vibrates. The shock-absorbing device in the prior art can only absorb vibration in a single direction and cannot achieve the vibration absorption process in multiple directions within the effective space, and is in urgent need of improvement. Summary of the Invention

[0005] The object of the present invention is to provide a digital hard disk video recorder with a vibration reduction and stabilization function and a vibration reduction method thereof, so as to solve the problems raised in the above background technology.

[0006] In order to achieve the above-mentioned object, the present invention provides the following technical solution: a digital hard disk video recorder with a shock absorption and stabilization function, comprising a digital hard disk video recorder body, a base is provided at the bottom end of the digital hard disk video recorder body, a universal seat is fixedly installed in the middle of the top end of the base, a frame is fixedly installed on the top end of the digital hard disk video recorder body, and limit guide rails are installed on the positions of the frame near the four corners, a movable plate is provided between the base and the digital hard disk video recorder body, support plates are installed on the left and right sides of the top end of the movable plate, auxiliary support components are installed on the positions of the top end of the movable plate near the four corners, the top end of the auxiliary support component is movably engaged with the limit guide rails, a universal telescopic ball rod is fixedly installed in the middle of the bottom end of the auxiliary support component, the bottom end of the universal telescopic ball rod is movably connected to the universal seat, the universal telescopic ball rod rotates relative to the universal seat, and a buffer component is installed between the base and the universal telescopic ball rod; When the bottom end of the digital hard disk video recorder body contacts the top end of the support plate, the universal telescopic ball rod is compressed and drives the movable plate to descend, and at the same time acts on the auxiliary support component to complete the limiting and fixing of the digital hard disk video recorder body, and the buffer component replaces the movable plate to perform overall buffering and shock absorption on the digital hard disk video recorder body.

[0007] Before use, the digital video recorder body and the auxiliary support assembly are in a separated state, and the universal telescopic ball rod is in an initial state. At this time, the support plate and the movable plate are at the highest point position, and the device is in an initial state, waiting for the assembly process with the digital video recorder body.

[0008] As a further technical solution of the present invention, when the universal telescopic ball rod is in the initial state, the length of the universal telescopic ball rod is at its maximum value, and the support plate is at its highest point. When the top end of the support plate contacts the bottom end of the digital hard disk recorder body, the universal telescopic ball rod is compressed.

[0009] In the initial state, the universal telescopic ball rod and the universal seat are in a vertical state. When the device vibrates, the vibration of the digital hard disk recorder body can be transmitted to the movable plate and the support plate through the auxiliary support assembly, and drive the universal telescopic ball rod to rotate. At this time, the universal telescopic ball rod can rotate relative to the universal seat and complete the buffering process through the buffer assembly.

[0010] As a further technical solution of the present invention, the auxiliary support assembly includes a guide block, which is movably connected to the limiting guide rail. The guide block is displaced left and right relative to the limiting guide rail, and a support seat is fixedly installed on the top of the guide block.

[0011] As a further technical solution of the present invention, when the digital video recorder body is completely placed above the support plate, the support seat and the side of the digital video recorder body contact and engage with each other, and the bottom end of the guide block is fixedly installed with a first fixing seat.

[0012] As a further technical solution of the present invention, the end of the first fixed seat away from the guide block is movably connected to the support rod through a rotating shaft, and the end of the support rod away from the first fixed seat is movably connected to the second fixed seat through a rotating shaft, and the bottom end of the second fixed seat is connected to the top end of the movable plate.

[0013] When the digital hard disk video recorder body needs to be assembled, the digital hard disk video recorder body can be placed on the support plate and the bottom end of the digital hard disk video recorder body is kept in contact with the top end of the support plate. At this time, the gravity of the digital hard disk video recorder body can apply a force to the universal telescopic ball rod, and the universal telescopic ball rod is compressed, and the movable plate is driven to move downward. At this time, the support plate lifts the digital hard disk video recorder body as a whole and moves downward. When the movable plate moves downward, the support rod is deflected toward the middle and a force is applied to the guide block. At this time, the guide block is displaced relative to the limit guide rail, that is, multiple guide blocks are displaced toward the middle of the rack, and finally drive multiple support seats to displace toward the middle of the rack until the support seats are in contact with the four corners of the digital hard disk video recorder body, completing the limit clamping process.

[0014] By utilizing the coordination between the support plate, the movable plate and the auxiliary support assembly, the digital hard disk video recorder body only needs to be placed in place, and the gravity of the digital hard disk video recorder body and the linkage action of the auxiliary support assembly can quickly realize the limiting and fixing process of the digital hard disk video recorder body. The whole process can be completed quickly without the complicated assembly process of traditional devices, and multi-point fixation can be achieved, which significantly improves the use efficiency of the device and reduces the difficulty of operation.

[0015] When the digital hard disk video recorder body needs to be separated, the movable plate can be manually pushed upward to drive the universal telescopic ball rod to reset. When the movable plate moves upward, the multiple support rods are deflected away from the middle. At this time, the multiple support seats can be moved away from the middle of the rack. At this time, the support seats are no longer in contact with the digital hard disk video recorder body, and the digital hard disk video recorder body can be separated upward.

[0016] By reusing the auxiliary support assembly and utilizing the cooperation between the auxiliary support assembly and the movable plate, the device can quickly complete the separation process of the digital hard disk recorder body, ensuring that when the digital hard disk recorder body needs to be moved, it can be quickly separated. The whole process is relatively fast, avoiding the complicated unlocking and separation process of traditional devices, and further improving the convenience of use of the device.

[0017] As a further technical solution of the present invention, the buffer assembly includes an upper fixing ring, which is fixedly connected to the outer side surface of the universal telescopic ball rod. The buffer assembly also includes a lower fixing ring, which is installed at the top of the base and located on the outer side surface of the universal seat.

[0018] As a further technical solution of the present invention, a third mounting seat is fixedly installed on the outer side of the upper fixing ring at equal axial intervals, and a fourth mounting seat is fixedly installed on the top of the lower fixing ring at equal axial intervals.

[0019] As a further technical solution of the present invention, movable seats are movably installed inside the third mounting seat and the fourth mounting seat, a damping rod is fixedly installed between the two movable seats, and buffer springs are movably sleeved on the upper and lower ends of the outer side of the damping rod.

[0020] As a further technical solution of the present invention, when the universal telescopic ball rod and the universal seat are perpendicular to each other, the buffer assembly is in an initial state, that is, the upper fixing ring and the lower fixing ring are parallel to each other, and the buffer spring is in a non-deformed state.

[0021] When the device vibrates, the vibration of the digital hard disk recorder body can be transmitted to the movable plate through the auxiliary support assembly, and then to the buffer assembly through the movable plate. At this time, the upper fixed ring can drive the universal telescopic ball rod to deflect at any angle relative to the universal seat. At this time, the buffer spring in the force direction is compressed, and the damping rod continues to compress with it, while the buffer spring in the non-force direction is stretched. At the same time, the damping rod can prevent it from further deformation, and multiple damping rods act at the same time, so that the buffer spring no longer deforms until the upper fixed ring recovers to be parallel to the lower fixed ring, completing the buffering and shock absorption process.

[0022] By coordinating the universal telescopic ball rod with the universal seat, and the coordinating action between the universal telescopic ball rod and the buffer assembly, the device does not need to set up buffer devices in multiple directions when performing shock absorption and buffering. Multi-dimensional shock absorption and buffering can be achieved by simply swinging the universal telescopic ball rod and suppressing the swing through the buffer assembly. This can effectively reduce space occupancy, provide multi-dimensional building buffering, and improve device stability.

[0023] A vibration reduction method for a digital video recorder with a vibration reduction and stabilization function comprises the following steps: S1: When installing the DVR, place the bottom of the DVR on top of the support plate. The universal telescopic rod is then compressed by the force, driving the support plate and the movable plate downward as a whole, and exerting force on the auxiliary support assembly. S2: When the movable plate moves downward, the multiple support rods deflect inward and apply tension to the guide block. The guide block then moves relative to the limit rail, driving the top support seat to move toward the DVR body until it makes contact with the four corners of the DVR body, completing the limit engagement process. S3: When the device vibrates, the digital video recorder body, the driving support plate and the movable plate vibrate synchronously, and the vibration is transmitted to the buffer assembly. At this time, the upper fixed ring drives the universal telescopic ball rod to rotate relative to the universal seat, and the damping rod deflects. At the same time, the buffer spring can be deformed. At the same time, the damping rod can prevent the buffer spring from deforming, completing the buffering and allowing the upper fixed ring to quickly reset and restore the parallel relationship between it and the lower fixed ring.

[0024] The beneficial effects of the present invention are as follows: (1) The present invention utilizes the cooperation between the support plate, the movable plate and the auxiliary support assembly so that the digital hard disk video recorder body only needs to be placed in place. The digital hard disk video recorder body can be quickly fixed by the gravity of the digital hard disk video recorder body and the linkage of the auxiliary support assembly. The whole process can be completed quickly without the complicated assembly process of the traditional device. Multi-point fixation can be achieved, which significantly improves the use efficiency of the device and reduces the difficulty of operation.

[0025] (2) The present invention coordinates the universal telescopic ball rod with the universal seat, and the universal telescopic ball rod with the buffer assembly, so that when the device performs shock absorption and buffering, there is no need to set up buffer devices in multiple directions. It only needs to swing the universal telescopic ball rod and suppress the swing through the buffer assembly to achieve multi-dimensional shock absorption and buffering, which can effectively reduce space occupation, provide multi-dimensional building buffering, and improve the stability of the device.

[0026] (3) The present invention reuses the auxiliary support assembly and utilizes the cooperation between the auxiliary support assembly and the movable plate to ensure that the device can quickly complete the separation process of the digital hard disk video recorder body and ensure that when the digital hard disk video recorder body needs to be moved, it can be quickly separated. The whole process is relatively fast and can avoid the complicated unlocking and separation process of traditional devices, further improving the convenience of use of the device.

[0031] Before use, the digital video recorder body 1 and the auxiliary support assembly 9 are in a separated state, and the universal telescopic ball rod 8 is in an initial state. At this time, the support plate 6 and the movable plate 7 are at the highest point position, and the device is in an initial state, waiting for the assembly process with the digital video recorder body 1.

[0032] like Figure 1 and Figure 2 as well as Figure 4 As shown, when the universal telescopic ball rod 8 is in the initial state, the length of the universal telescopic ball rod 8 is at the maximum value, and the support plate 6 is at the highest point. When the top end of the support plate 6 contacts the bottom end of the digital hard disk recorder body 1, the universal telescopic ball rod 8 is compressed.

[0033] In the initial state, the universal telescopic ball rod 8 is in a vertical state with respect to the universal seat 3. When the device vibrates, the vibration of the digital hard disk recorder body 1 can be transmitted to the movable plate 7 and the support plate 6 through the auxiliary support assembly 9, and drive the universal telescopic ball rod 8 to rotate. At this time, the universal telescopic ball rod 8 can rotate relative to the universal seat 3, and the buffering process is completed through the buffer assembly 10.

[0034] like Figure 1 and Figure 2 as well as Figure 5 and Figure 6 As shown, the auxiliary support assembly 9 includes a guide block 901, which is movably connected to the limit guide rail 5, and the guide block 901 is displaced left and right relative to the limit guide rail 5. The top of the guide block 901 is fixedly installed with a support seat 902. When the digital hard disk recorder body 1 is completely placed above the support plate 6, the support seat 902 and the side of the digital hard disk recorder body 1 are in contact with each other and are engaged. The bottom end of the guide block 901 is fixedly installed with a first fixed seat 903, and the end of the first fixed seat 903 away from the guide block 901 is movably connected to the support rod 905 through a rotating shaft, and the end of the support rod 905 away from the first fixed seat 903 is movably connected to the second fixed seat 904 through a rotating shaft, and the bottom end of the second fixed seat 904 is connected to the top of the movable plate 7.

[0035] When the cam 8 is in contact with the top of the support plate 6, the support plate 6 will move downwards, and the support plate 6 will lift the cam 8 to move downwards. When the cam 8 is in contact with the top of the support plate 6, the support plate 6 will lift the cam 8 to move downwards. When the cam 8 is in contact with the top of the support plate 6, the support plate 6 will lift the cam 8 to move downwards. When the cam 8 is in contact with the top of the support plate 6, the support plate 6 will lift the cam 8 to move downwards. When the cam 8 is in contact with the top of the support plate 6, the support plate 6 will lift the cam 8 to move downwards.

[0036] By utilizing the cooperation between the support plate 6, the movable plate 7 and the auxiliary support assembly 9, it is only necessary to place the digital hard disk video recorder body 1 in place, and the gravity of the digital hard disk video recorder body 1 and the linkage effect of the auxiliary support assembly 9 can quickly realize the limiting and fixing process of the digital hard disk video recorder body 1. The whole process can be completed quickly, and multi-point fixation can be achieved without the complicated assembly process of traditional devices, which significantly improves the use efficiency of the device and reduces the difficulty of operation.

[0037] When the digital video recorder body 1 needs to be separated, the movable plate 7 can be manually pushed upward to drive the universal telescopic ball rod 8 to reset. When the movable plate 7 moves upward, the multiple support rods 905 are deflected away from the middle. At this time, the multiple support seats 902 can be moved away from the middle of the frame 4. At this time, the support seats 902 are no longer in contact with the digital video recorder body 1, and the digital video recorder body 1 can be separated upward.

[0038] By reusing the auxiliary support assembly 9 and utilizing the cooperation between the auxiliary support assembly 9 and the movable plate 7, it is ensured that the device can quickly complete the separation process of the digital hard disk recorder body 1, and ensure that when the digital hard disk recorder body 1 needs to be moved, it can be quickly separated. The whole process is relatively fast, and the complicated unlocking and separation process of traditional devices can be avoided, further improving the convenience of use of the device.

[0039] like Figure 1 He Ru Figure 2 as well as Figure 7 and Figure 8As shown, the buffer assembly 10 includes an upper fixing ring 101, which is fixedly sleeved with the outer side surface of the universal telescopic ball rod 8. The buffer assembly 10 also includes a lower fixing ring 102, which is installed at the top of the base 2 and located on the outer side surface of the universal seat 3. The outer side surface of the upper fixing ring 101 is fixedly installed with a third mounting seat 103 at axial equal intervals, and the top of the lower fixing ring 102 is fixedly installed with a fourth mounting seat 104 at axial equal intervals. The interiors of the third mounting seat 103 and the fourth mounting seat 104 are both movably installed with movable seats 105, and a damping rod 107 is fixedly installed between the two movable seats 105. The upper and lower ends of the outer side surface of the damping rod 107 are movably sleeved with buffer springs 106. When the universal telescopic ball rod 8 and the universal seat 3 are perpendicular to each other, the buffer assembly 10 is in an initial state, that is, the upper fixing ring 101 and the lower fixing ring 102 are parallel to each other, and the buffer spring 106 is in a non-deformed state.

[0040] Embodiment: When the device vibrates, the vibration of the digital hard disk recorder body 1 can be transmitted to the movable plate 7 through the auxiliary support assembly 9, and then transmitted to the buffer assembly 10 through the movable plate 7. At this time, the upper fixed ring 101 can drive the universal telescopic ball rod 8 to deflect at any angle relative to the universal seat 3. At this time, the buffer spring 106 in the force direction is compressed, and the damping rod 107 continues to be compressed, while the buffer spring 106 in the non-force direction is stretched. At the same time, the damping rod 107 can prevent it from further deformation, and multiple damping rods 107 act at the same time, so that the buffer spring 106 no longer deforms until the upper fixed ring 101 recovers its parallel state with the lower fixed ring 102, completing the buffering and shock absorption process.

[0041] By coordinating the universal telescopic ball rod 8 with the universal seat 3, and the coordinating action between the universal telescopic ball rod 8 and the buffer assembly 10, the device does not need to set up buffer devices in multiple directions when performing shock absorption and buffering. It only needs to swing the universal telescopic ball rod 8 and suppress the swing through the buffer assembly 10 to achieve multi-dimensional shock absorption and buffering, which can effectively reduce space occupancy, provide multi-dimensional building buffering, and improve the stability of the device.

[0042] A vibration reduction method for a digital video recorder with a vibration reduction and stabilization function comprises the following steps: S1: When installing the DVR body 1, place the bottom end of the DVR body 1 above the support plate 6. At this time, the universal telescopic ball rod 8 is compressed by the force, and drives the support plate 6 and the movable plate 7 to move downward as a whole, and exerts force on the auxiliary support assembly 9; S2: When the movable plate 7 moves downward, the multiple support rods 905 deflect toward the inner side and apply tension to the guide block 901. At this time, the guide block 901 moves relative to the limit guide rail 5, and at the same time drives the top support seat 902 to move toward the direction of the digital video recorder body 1 until it contacts the four corners of the digital video recorder body 1, completing the limit engagement process; S3: When the device vibrates, the digital video recorder body 1 and the driving support plate 6 and the movable plate 7 vibrate synchronously, and the vibration will be transmitted to the buffer assembly 10. At this time, the upper fixed ring 101 drives the universal telescopic ball rod 8 to rotate relative to the universal seat 3, and the damping rod 107 is deflected. At the same time, the buffer spring 106 can be deformed. At the same time, the damping rod 107 can prevent the buffer spring 106 from deforming, completing the buffering and allowing the upper fixed ring 101 to quickly reset and restore the parallel relationship with the lower fixed ring 102.

[0043] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.

At this time, the upper fixed ring (101) drives the universal telescopic ball rod (8) to rotate relative to the universal seat (3), and the damping rod (107) deflects. At the same time, the buffer spring (106) can be deformed. At the same time, the damping rod (107) can prevent the buffer spring (106) from deforming, completing the buffering and allowing the upper fixed ring (101) to quickly reset and restore the parallel relationship with the lower fixed ring (102).
