Description

Technical Field

[0001] This invention belongs to the field of vibration reduction technology for vehicle-mounted shooting equipment, and specifically relates to a vibration damping head and vibration damping mechanism. Background Technology

[0002] When using vehicle-mounted camera equipment to shoot moving shots, such as filming vehicles in motion, indoors and outdoors, auxiliary tools like vehicles are often used to attach the camera to a vehicle-mounted camera bracket to keep the camera in track of the shot. However, during filming, road conditions can affect the camera and the camera bracket, causing the lens to shake during movement. To minimize shaking and stabilize the footage, structures like vibration-damping arms are typically used to mount the camera. Traditional vibration-damping arms usually use damping springs mounted on the arm body, with a camera connection component attached to the head of the arm body. The damping springs cushion the overall structure.

[0003] For example, the existing patent application CN202110273411.8 discloses a shock absorber head, a vehicle-mounted shock absorber arm, and a vehicle-mounted shooting device. The shock absorber head includes an external structure, a buffer assembly, and a connecting assembly. The buffer assembly includes at least one first slide rod and a second slide rod arranged in parallel and spaced apart. The first slide rod and the second slide rod are arranged perpendicularly and each is fitted with two elastic elements. The external structure is slidably sleeved on the second slide rod and clamped between the two elastic elements of the second slide rod. The second slide rod is slidably sleeved on the first slide rod and clamped between the two elastic elements of the first slide rod. The connecting assembly is fixedly connected to the buffer assembly and is used for connecting external photography accessories. The elastic elements in this patent are springs. When the gimbal moves back and forth in a direction parallel to the first slide rod or the second slide rod, the spring will compress or stretch, thereby slowing down the left-right or back-and-forth movement of the camera mounted on the gimbal and achieving shock absorption.

[0004] As can be seen from the above, the shock-absorbing arm structure disclosed in the above patent uses shock-absorbing springs to buffer the overall structure. However, during the shooting process, due to the inevitable shaking and lateral inertia of the camera, the camera is prone to lose control from the head of the shock-absorbing arm body, making it difficult to balance the loss of stability caused by the camera's shaking or lateral inertia. Summary of the Invention

[0005] To address the aforementioned problems, the primary objective of this invention is to provide a shock-absorbing head and mechanism that, when the support component tends to swing, can use its own telescopic movement to cause the support component to swing back and forth or left and right, thereby buffering the centrifugal force of the camera's swing, preventing the camera from detaching from the shock-absorbing arm, and also preventing camera shake, thus ensuring the stability of the captured footage.

[0006] To achieve the above objectives, the technical solution of the present invention is as follows:

[0007] This invention provides a shock absorber head, comprising a connector, a movable component, a support component, and a shock-absorbing structure. The shock-absorbing structure is movably connected to the connector and the movable component, respectively. One end of the movable component is movably connected to the connector, and the other end of the movable component is movably connected to the support component. The end of the shock-absorbing structure furthest from the connector is movably connected to the support component. In this application, the support component is used to mount equipment requiring shock absorption, such as cameras. The connector is used to install the shock absorber head on an external structure such as a vehicle camera bracket. The shock-absorbing structure can drive the support component to swing back and forth or left and right, providing rotational buffering and shock absorption. The movable component enables the movable connection between the connector and the support component, achieving freedom of movement for the support component while ensuring its structural stability, thus ensuring that the support component's back-and-forth and left-and-right swing is undisturbed. During filming, when the camera experiences horizontal shaking and inertial movement, the shock-absorbing structure can move its own movement to cause the support and the camera to swing back and forth or left and right in the corresponding direction, and the relative connecting parts to move, thereby buffering the centrifugal force of the camera swinging, preventing the camera from falling off the shock-absorbing arm, and also preventing the camera from shaking, thus ensuring the stability of the filming footage.

[0008] Furthermore, the damping structure includes a damping component and a transmission component. One end of the damping component is fixedly connected to the connecting member, and the other end is movably connected to the transmission component. The end of the transmission component away from the damping component is movably connected to the support member, and the end of the movable member away from the support member is movably connected to the transmission component. In this application, the damping component transmits power through the transmission component, indirectly driving the support member to move, thereby improving the stability of the structure.

[0009] Furthermore, the connector includes a connecting arm with a movable position, a movable component is mounted on the movable position, and a transmission assembly is located on the side of the movable position. The side wall of the movable position, the transmission assembly, and the movable component are coaxially and movably connected. When the shock-absorbing assembly operates, the movable component and the transmission assembly can rotate synchronously, causing the support component to swing, thereby improving the stability of the structure.

[0010] Furthermore, the shock absorption assembly includes a shock absorption body and a telescopic part. The shock absorption body is fixed to the side wall of the connector, one end of the telescopic part is movably connected to the transmission assembly, and the other end is movably disposed within the shock absorption body.

[0011] Furthermore, the shock-absorbing body includes a shock-absorbing fixing component and a shock-absorbing guide sleeve. The shock-absorbing guide sleeve is fixed to the side wall of the connecting component by the shock-absorbing fixing component. One end of the telescopic part is movably connected to the transmission component, and the other end of the telescopic part is movably disposed inside the shock-absorbing guide sleeve. In this application, when the camera experiences horizontal shaking and inertia during shooting, causing the camera to swing, the support component will also swing accordingly. At this time, the telescopic part can extend or retract the shock-absorbing guide sleeve to pull or push the transmission component at its output end, thereby moving the support component to buffer the centrifugal force of the camera's swing and ensure the stability of the shot.

[0012] Furthermore, the transmission assembly includes a first transmission member and a second transmission member. One end of the first transmission member is connected to one end of the telescopic part, and the other end is rotatably connected to one end of the second transmission member. The other end of the second transmission member is rotatably connected to the support member, and the middle part of the first transmission member is rotatably connected to the movable member and the connecting member.

[0013] Furthermore, the shock absorber head also includes a movable shaft, which includes a first shaft portion and a second shaft portion. A first rotating shaft seat is provided on the movable component, and a second rotating shaft seat is provided on the support component. The first shaft portion is rotatably connected to the first rotating shaft seat, and the second shaft portion is rotatably connected to the second rotating shaft seat.

[0014] Furthermore, the shock-absorbing structure includes multiple structures, with two of the shock-absorbing structures located on both sides of the connector, and the movable component and movable shaft located between the two shock-absorbing structures.

[0015] Furthermore, a mounting base is provided on each of the left and right sides of the support member, and a support shaft is provided on the mounting base. The two shock-absorbing structures are rotatably connected to the support shaft, and the second rotating shaft seat is located on the center line of the two mounting bases. In this application, two sets of shock-absorbing structures are provided, respectively located on the left and right sides of the connecting arm. They can move by their own extension and retraction, pulling or pushing the transmission component. When both are retracted, they will pull the transmission component backward; when both are extended, they will push the transmission component forward. When they extend or retract simultaneously, they pull or push the transmission component synchronously, which can cause the support member to swing back and forth, buffering the centrifugal force caused by the back and forth movement of the camera. When they extend and retract in a cross manner, they pull or push the transmission component in a cross manner, which can cause the support member to swing left and right, buffering the centrifugal force caused by the left and right swing of the camera. In this way, through the cooperation of different pulling or pushing forces, the support member can swing back and forth and left and right in a horizontal direction to buffer the swing of the camera at any angle, thereby ensuring the stability of the camera's shooting image.

[0016] The present invention also provides a damping mechanism using the above-mentioned damping head. The damping mechanism includes a base, a buffer assembly, a damping assembly, a damping arm, and a damping head. One end of the damping arm is connected to the connecting member, and the other end is rotatably connected to the base. The damping assembly is disposed on the damping arm and movably connected to the buffer assembly. The end of the buffer assembly away from the damping assembly is rotatably connected to the base.

[0017] Furthermore, two shock-absorbing arms are provided, arranged side by side, with the front end of each shock-absorbing arm connected to the end of a connecting arm. The two shock-absorbing components are respectively fixedly connected to the outer sides of the two shock-absorbing arms.

[0018] Furthermore, the buffer assembly includes a first connecting rod and a second connecting rod, and the damping assembly includes a damping telescopic shaft and a damping guide sleeve. One end of the first connecting rod is rotatably connected to the base, and the other end is rotatably connected to one end of the second connecting rod. The other end of the second connecting rod is movably connected to the output end of the damping telescopic shaft, and the end of the damping telescopic shaft away from the second connecting rod is movably disposed within the damping guide sleeve. The end of the damping guide sleeve away from the damping telescopic shaft is rotatably connected to the bottom of the end of the shock absorber arm. In this application, the damping telescopic shaft can extend and retract within the damping guide sleeve to adjust its length, thereby coordinating with the rotation of the buffer assembly to adjust the stability of the shock absorber arm during rotation. Specifically, when the shock absorber arm rotates up and down relative to the base, the damping telescopic shaft can drive the second connecting rod to rotate through its own extension and retraction, and the second connecting rod drives the first connecting rod to rotate, thereby adjusting the swaying and impact force brought about by the rotation of the shock absorber arm and improving the stability of the shock absorber arm rotation.

[0019] Furthermore, the second link has a bend structure, and the bend of the second link is fixedly connected to the shock absorber arm. The second link can be connected to the shock absorber arm through the bend structure, thereby improving the stability of the structure.

[0020] The advantage of this invention is that, compared with the prior art, the shock-absorbing head of this shock-absorbing mechanism can drive the support to swing back and forth or left and right through its own telescopic movement when the support tends to swing, thereby buffering the centrifugal force of the camera swinging, preventing the camera from falling off the shock-absorbing arm, and also preventing the camera from shaking, thus ensuring the stability of the shooting footage.

[0032] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0033] To achieve the above objectives, the technical solution of this embodiment is as follows:

[0034] See Figure 1-4 As shown, this embodiment provides a shock absorption mechanism, including a shock absorption head 1. The shock absorption head 1 includes a connector 11, a movable member 12, a support member 13, and a shock absorption structure. The shock absorption structure is movably connected to the connector 11 and the movable member 12. One end of the movable member 12 is movably connected to the connector 11, and the other end of the movable member 12 is movably connected to the support member 13. The end of the shock absorption structure 100 away from the connector 11 is movably connected to the support member 13.

[0035] Furthermore, the shock absorption structure is provided in two sets, namely a first shock absorption structure 100 and a second shock absorption structure 200. The first shock absorption structure 100 includes a first shock absorption component 14 and a first transmission component 15. One end of the first shock absorption component 14 is fixedly connected to the connector 11, and the other end is movably connected to the first transmission component 15. The end of the first transmission component 15 away from the first shock absorption component 14 is movably connected to the support member 13. The end of the movable member 12 away from the support member 13 is movably connected to the first transmission component 15. In this embodiment, the first shock absorption assembly 14 and the first transmission component 15 can be combined to form a first set of shock absorption structures, and the second shock absorption assembly 16 and the second transmission component 17 can be combined to form a second set of shock absorption structures. The two sets of shock absorption structures are respectively located on the left and right sides of the connector, and can achieve the horizontal back-and-forth and left-and-right swing of the support member 13 through synergistic action to buffer the swing of the camera at any angle, thereby ensuring the stability of the camera's shooting footage.

[0036] Furthermore, the first damping assembly 14 includes a first damping fixing member 141, a first damping guide sleeve 142, and a first telescopic part 143. The first damping fixing member 141 and the first damping guide sleeve 142 are combined to form the first damping body. The first transmission assembly 15 includes a first rotating triangular member 151 and a first transmission rod 152. The first damping guide sleeve 142 is fixed to the side wall of the connector 11 through the first damping fixing member 141. The front end of the first telescopic part 143 is movably connected to the upper end of the first rotating triangular member 151, and the end end is movably disposed within the first damping guide sleeve 142. The lower end of the first rotating triangular member 151 is rotatably connected to the upper end of the first transmission rod 152, and the lower end of the first transmission rod 152 is rotatably connected to the support member 13.

[0037] Furthermore, the second damping assembly 16 includes a second damping fixing member 161, a second damping guide sleeve 162, and a second telescopic part 163. The second damping fixing member 161 and the second damping guide sleeve 162 are combined to form the second damping body. The second transmission assembly 17 includes a second rotating triangular member 171 and a second transmission rod 172. The second damping guide sleeve 162 is fixed to the side wall of the connector 11 by the second damping fixing member 161. The front end of the second telescopic part 163 is rotatably connected to the upper end of the second rotating triangular member 171, and the end is movably disposed within the second damping guide sleeve 162. The lower end of the second rotating triangular member 171 is rotatably connected to the upper end of the second transmission rod 172, and the lower end of the second transmission rod 172 is rotatably connected to the support member 13.

[0038] In this application, both the first damping component 14 and the second damping component 16 adopt a titanium ruler structure, and the damping function is achieved through the expansion and contraction of the titanium ruler.

[0039] Furthermore, the connecting member 11 includes a connecting arm 111, on which a movable position 113 is provided. The upper end of the movable member 12 is rotatably connected to the movable position. The first rotating triangular member 151 and the second rotating triangular member 171 are provided on both sides of the movable position, and the side wall of the movable position, the first rotating triangular member 151, the second rotating triangular member 171, and the upper movable position are coaxially rotatably connected. When the first damping assembly 14 and the second damping assembly 16 are activated, the movable member 12, the first rotating triangular member 151, and the second rotating triangular member 171 can rotate synchronously, causing the supporting member 13 to swing, which can improve the stability of the structure.

[0040] Furthermore, the shock absorber head 1 also includes a movable shaft, which is a cross pivot 18. The movable component 12 and the cross pivot 18 are sandwiched between the first transmission assembly 15 and the second transmission assembly 17. The lower end of the movable component 12 is provided with a first rotating shaft seat 121, and the support component 13 is provided with a second rotating shaft seat 131. The support component 13 is provided with a mounting seat 132 on the left and right sides of the second rotating shaft seat 131, and a steering pin is provided on the mounting seat 132. The lower ends of the first transmission rod 152 and the second transmission rod 172 are rotatably connected to the steering pins on the left and right sides, respectively. The cross pivot 18 includes a first shaft portion and a second shaft portion that are perpendicular to each other. The first shaft portion is rotatably connected to the first rotating shaft seat 121, and the second shaft portion of the cross pivot 18 is rotatably connected to the second rotating shaft seat 131.

[0041] In this embodiment, the support member 13 is used to mount equipment requiring shock absorption, such as a camera. The connecting member 11 is used to install the shock absorber head 1 on an external structure such as a vehicle camera bracket. The first shock absorption component 14 can drive the support member 13 to swing back and forth or left and right through the first transmission component 15. The second shock absorption component 16 can drive the support member 13 to swing back and forth or left and right through the second transmission component 17, providing rotational buffering and shock absorption functions. The movable member 12 can achieve a rotational connection between the connecting arm 111 and the support member 13 through the cross pivot 18. Under the premise of ensuring the structural stability of the support member 13, the freedom of movement of the support member 13 is realized, ensuring that the swing of the support member 13 in the back and forth and left and right is not disturbed. During the shooting process, when the camera experiences horizontal shaking and inertial movement, the telescopic parts located on the left and right sides of the connecting arm 111 can extend and retract within the shock absorption guide sleeve. They pull or push the transmission component by their own extension and retraction. When the two retract, they pull the transmission component backward; when the two extend, they push the transmission component forward. When they extend or retract simultaneously, the two pull or push the transmission components in sync, which can cause the support component 13 to swing back and forth, buffering the centrifugal force caused by the camera's back and forth movement. When they extend or retract in a cross manner, they pull or push the transmission components in a cross manner, which can cause the support component 13 to swing left and right, buffering the centrifugal force caused by the camera's swaying. In this way, through the cooperation of different pulling or pushing forces, the support component 13 can swing back and forth and left and right in the horizontal direction, so as to buffer the camera's swinging at any angle, prevent the camera from falling off the shock-absorbing arm 112, and thus ensure the stability of the camera's shooting footage.

[0042] Furthermore, the shock absorption mechanism in this embodiment also includes a base 2, a buffer assembly 3, and a damping assembly 4. The end of the shock absorption arm 112 is rotatably connected to the base 2 on the same axis. The end of the buffer assembly 3 is rotatably connected to the base 2, and the front end is rotatably connected to the end of the damping assembly 4. The front end of the damping assembly 4 is rotatably connected to the front end of the shock absorption arm 112.

[0043] Furthermore, the connector 11 also includes a shock-absorbing arm 112. Two shock-absorbing arms 112 are provided and arranged side by side. The first shock-absorbing fixing member 141 and the second shock-absorbing fixing member 161 are respectively fixedly connected to the outside of the two shock-absorbing arms 112, and the front end of the shock-absorbing arm 112 is connected to the end of the connector 111.

[0044] Furthermore, the buffer assembly 3 includes a first connecting rod 31 and a second connecting rod 32, and the damping assembly 4 includes a damping telescopic shaft 41 and a damping guide sleeve 42. The end of the first connecting rod 31 is rotatably connected to the base 2, and the front end is rotatably connected to the end of the second connecting rod 32. The front end of the second connecting rod 32 is movably connected to the output end of the damping telescopic shaft 41, and the end of the damping telescopic shaft 41 away from the second connecting rod 32 is movably disposed within the damping guide sleeve 42. The end of the damping guide sleeve 42 away from the damping telescopic shaft 41 is rotatably connected to the bottom of the front end of the shock absorber arm 112. In this application, the damping telescopic shaft 41 can extend and retract within the damping guide sleeve 42 to adjust its length, thereby adjusting the stability of the shock absorber arm 112 during rotation in conjunction with the rotation of the buffer assembly 3. Specifically, when the shock absorber arm 112 rotates up and down relative to the base 2, the damping telescopic shaft 41 can drive the second link 32 to rotate through its own extension and retraction, and the second link 32 drives the first link 31 to rotate, thereby adjusting the swaying and impact force brought about by the rotation of the shock absorber arm 112 and improving the stability of the rotation of the shock absorber arm 112. In this embodiment, the damping component 4 adopts a damping titanium ruler, which uses the principle of the titanium ruler to realize damping extension and retraction, buffering swaying and impact force.

[0045] Furthermore, the second link 32 has a bend structure, and the bend of the second link 32 is fixedly connected to the shock absorber arm 112. The second link 32 can be connected to the shock absorber arm 112 through the bend structure, thereby improving the stability of the structure.

[0046] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
