[0003] At present, when shooting sports scenes with a mobile lens indoors or outdoors, in order to keep the images captured by the camera stable and smooth, the shock-absorbing structure generally uses a spring structure as a buffering energy-absorbing mechanism, which buffers and absorbs energy through the spring elasticity and compressible and stretchable stroke change characteristics.

[0004] The traditional spring shock absorber arm is used as a buffer component, and the shooting equipment is loaded on the shock absorbing mechanism. Affected by the road surface, when the camera equipment is pitching, if the stroke of the buffer component changes greatly, the photographic equipment loaded by the shock absorbing structure will be more unstable, thus making the shooting more unstable.

[0014] In another embodiment, the connecting body includes a connecting portion and an adjusting portion, and the adjusting portion can rotate to move the connecting rod to adjust the angle between the buffer assembly and the shock absorbing main arm.

[0015] In another embodiment, the adjusting part includes an adjusting screw, one end of which passes through the connecting part and is rotatably arranged on the connecting part, and the other end is arranged as an adjusting end and is located outside the connecting part; the connecting rod is threadedly connected to the adjusting screw, and the adjusting screw is rotated to adjust the connecting rod to move along the length direction of the adjusting screw.

[0016] In another embodiment, the adjusting portion further includes at least one adjusting connecting rod, wherein the adjusting connecting rod is mounted on the connecting portion, and the connecting rod has an opening for the adjusting connecting rod to pass through, so that the adjusting connecting rod can be movably connected to the connecting rod.

DETAILED DESCRIPTION

[0031] The present application is further described in detail below by specific embodiments in conjunction with the accompanying drawings. Wherein similar elements in different embodiments adopt associated similar element numbers. In the following embodiments, many detailed descriptions are intended to enable the present application to be better understood.

In some cases, some operations related to the present application are not shown or described in the specification, in order to avoid the core part of the present application being overwhelmed by too much description, and for those skilled in the art, it is not necessary to describe these related operations in detail, and they can fully understand the related operations based on the description in the specification and the general technical knowledge in the art.

[0032] In addition, the features, operations or characteristics described in the specification can be combined in any appropriate manner to form various implementations, and the operation steps involved in each embodiment can also be replaced or adjusted in a sequence in a manner that is obvious to those skilled in the art. Therefore, the specification and drawings are only for the purpose of clearly describing a certain embodiment and do not mean that the composition and / or sequence are necessary.

[0033] The serial numbers of the components in this document, such as "first", "second", etc., are only used to distinguish the objects described and do not have any order or technical meaning. The "connection" and "coupling" mentioned in this application, unless otherwise specified, include direct and indirect connections (couplings).

[0034] When shooting sports scenes with a moving lens indoors or outdoors, in order to keep the images taken by the camera stable and smooth, some camera equipment shock-absorbing devices are usually needed to keep the images taken by the camera stable. The shock-absorbing structure in the prior art generally uses a spring structure as a buffering energy-absorbing mechanism, which buffers and absorbs energy through the spring elasticity and compressible and stretchable stroke change characteristics.

[0035] The traditional spring shock absorber arm is used as the buffer component 3, and the camera equipment is loaded on the shock absorbing mechanism. Affected by the road surface, when the camera equipment is pitching, if the stroke of the buffer component 3 changes, the stroke of the loaded camera equipment will also be larger, making the shooting more unstable. Moreover, the larger the spring stroke, the easier it is for metal fatigue to occur, and the shock absorption strength and rebound speed cannot be quickly adjusted according to the camera's own weight. When the shock absorbing device needs to adapt to machines of different weights, the spring usually needs to be replaced, which is very inconvenient.

[0036] The present application provides a shock absorbing arm, which provides an active buffer zone between the shock absorbing main arm 1, the base 2 and the buffer assembly 3, and buffers the change in the movement stroke of the buffer assembly 3 through the activity of the connecting rod mechanism, thereby reducing the amplitude of the loaded photographic equipment and improving the stability of shooting.

[0037] In one embodiment, a shock absorbing arm is provided, please refer to Figure 1 and Figure 2 , including a shock-absorbing main arm 1, a base 2, a buffer component 3 and a connecting component 4; the front end of the shock-absorbing main arm 1 is used to load the camera equipment; the base 2 is rotatably connected to the rear end of the shock-absorbing main arm 1; the buffer component 3 is rotatably connected to the front end of the shock-absorbing main arm 1 and is used for load buffering; the connecting component 4 is used to connect the shock-absorbing main arm 1, the base 2 and the buffer component 3 to form a buffer zone.

[0038] Specifically, the connecting component 4 includes a first connecting member 41 movably connected to the base 2 and a second connecting member 42 movably connected to the shock absorbing main arm 1; the first connecting member 41 is movably connected to the second connecting member 42 at one end away from the base 2, and the second connecting member 42 is movably connected to the free end of the buffer component 3. The connecting component 4 forms a buffer zone between the shock absorbing main arm 1, the base 2 and the buffer component 3 to reduce the change in the movement stroke of the buffer component 3.

[0039] In the shock absorbing arm in the embodiment of the present application, the shock absorbing main arm 1, the base 2 and the buffer assembly 3 are movably connected by the first connecting member 41 and the second connecting member 42, and each movable connection position is rotatably connected by a rotating shaft, and the rotating shafts on the shock absorbing main arm 1, the first connecting member 41 and the second connecting member 42 are all arranged in parallel, so that a bufferable connecting assembly 4 is formed between the shock absorbing main arm 1, the base 2 and the buffer assembly 3, and the connecting assembly 4 forms a buffer zone similar to a connecting rod mechanism through the first connecting member 41, the second connecting member 42 and the shock absorbing main arm 1 and the base 2, so that when the road conditions make the shock absorbing main arm 1 have a pitch tendency, the first connecting member 41 and the second connecting member 42 are movably connected, so that the first connecting member 41 and the second connecting member 42 can follow the swing, thereby reducing the change in the stroke of the buffer assembly 3, thereby buffering the change in the stroke of the buffer assembly 3, and the amplitude of the loaded photographic equipment in the vertical direction is reduced, so the loaded photographic equipment is relatively stable, thereby improving the stability of shooting.

[0040] Please refer to Figure 1 The front end of the shock-absorbing main arm 1 includes a shock-absorbing head 11, which is used to assemble photographic accessories equipped with a camera device. The shock-absorbing head 11 can be used to assemble the camera device, which usually includes a shooting camera equipped with photographic accessories. The photographic accessories, such as a stabilizer and a full cage, are used to protect and expand the camera function, provide additional equipment installation space and a power supply system, and the front end of the shock-absorbing main arm 1 is used as a whole to support the load camera equipment.

[0041] Please refer to Figure 2 and Figure 3The second connecting member 42 includes a connecting body 421 and a connecting rod 423. One end of the connecting rod 423 is connected to the connecting body 421, and the other end is rotatably connected to the free end of the buffer assembly 3. Both ends of the first connecting member 41 are movable, and both ends of the connecting rod 423 are also movable. Through the activities of the connecting body 421, the first connecting member 41 and the connecting rod 423, the carried weight can be buffered by the buffer assembly 3 and the activities between the connecting assembly 4, thereby reducing the change in the stroke formed by the movement of the buffer assembly 3, and the amplitude of the loaded photographic equipment is reduced accordingly, thereby improving the stability of shooting. The free end of the buffer assembly 3 is movably connected to the connecting body 421 through the connecting rod 423, making the two ends of the buffer assembly 3 more flexible.

[0042] Please refer to Figure 3 The second connecting member 42 also includes a connecting position 422 arranged on the connecting body 421. In the embodiment of the present application, the connecting body 421 is generally arranged in a triangular shape as a whole. The connecting position 422 is used to connect the shock absorbing main arm 1. The connecting position 422 is arranged at any corner and extended to increase the adjustable range of the connecting body 421.

[0043] Please refer to Figures 4(a) and 4(b). When the shock absorbing main arm 1 pitches, the first connecting member 41, the second connecting member 42 and the connecting rod 423 are movable so that the first connecting member 41 and the second connecting member 42 can swing slightly, thereby buffering the change in stroke caused by the movement of the buffer assembly 3.

[0044] Taking Figure 4(b) as an example, when the road condition causes the shock absorber main arm 1 to have an upward tendency, the buffer component 3 will have a corresponding deformation change. The area in the dotted box on the left side of Figure 4(b) swings toward the buffer component 3 with the connection point between the second connecting member 42 and the shock absorber main arm 1 as the fulcrum (the perspective in Figure 4(b) is a right swing), thereby reducing the change of the buffer component 3; when the roadside condition causes the shock absorber main arm 1 to have a downward tendency, the buffer component 3 will also have a corresponding deformation change. The area in the dotted box on the left side of Figure 4(b) swings away from the buffer component 3 with the connection point between the second connecting member 42 and the shock absorber main arm 1 as the fulcrum (the perspective in Figure 4(b) is a left swing), thereby reducing the change of the buffer component 3.

[0045] Please refer to Figure 3The connecting body 421 includes a connecting portion 44 and an adjusting portion 43. The adjusting portion 43 can rotate to move the connecting rod 423 to adjust the angle between the buffer assembly 3 and the shock absorbing main arm 1. Specifically, the first connecting member 41 is set as a connecting rod structure and is rotatably installed at another corner of the connecting body 421. Further, the last corner of the second connecting member 42 is set with an adjusting portion 43. The connecting rod 423 is installed on the adjusting portion 43. The adjusting portion 43 can rotate to move the connecting rod 423 to adjust the position of the connecting rod 423 and the buffer assembly 3 on the second connecting member 42, thereby adjusting the angle between the buffer assembly 3 and the shock absorbing main arm 1. In the embodiment of the present application, it is equivalent to that the shock absorbing main arm 1, the base 2 and the buffer assembly 3 are movably connected at the three corners of the connecting body 421 respectively. The force loaded on the buffer assembly 3 is buffered again by the movement of the connecting body 421 in the buffer zone, thereby reducing the stroke of the buffer assembly 3.

[0046] For details, please refer to Figure 5 The adjusting portion 43 includes an adjusting screw 431, an adjusting knob 432 and at least one adjusting connecting rod 433. The connecting portion 44 is hollow and has an opening for the adjusting screw 431 to penetrate. The front end of the adjusting screw 431 penetrates into the connecting portion 44 from the opening and is rotatably connected to the connecting portion 44. Specifically, an inner groove is provided on the inner wall of the connecting portion 44, and a bearing is installed in the inner groove. The bearing is provided in the inner groove and sleeved on the front end of the adjusting screw 431, so that the adjusting screw 431 is rotatably connected to the connecting portion 44 through the bearing; a support seat is provided at the opening, and the outer ring of the support seat is threadedly connected to the opening, and the inner ring is for the adjusting screw 431 to pass through. An annular gasket is fixedly connected to the peripheral side wall of the adjusting screw 431 near the rear end, and the annular gasket is located between the bearing and the support seat and supported by the support seat to limit the adjusting screw 431 from detaching from the connecting portion 44. The rear end of the adjusting screw 431 is set as the adjusting end and is outside the inner cavity of the connecting part 44. The adjusting knob 432 is installed on the adjusting end of the adjusting screw 431. The adjusting knob 432 and the adjusting screw 431 are relatively fixed in the circumferential direction. The connecting rod 423 is threadedly connected to the adjusting screw 431. The adjusting screw 431 rotates to adjust the connecting rod 423 and the connected buffer assembly 3 to move along the length direction of the adjusting screw 431, which is convenient for controlled operation and adjustment on the outside of the second connecting member 42. The axis of the adjusting screw 431 is perpendicular to the axis of the rotating shaft on the second connecting member 42, thereby changing the position of the buffer assembly 3 on the connecting body 421 and changing the load-bearing point, so that heavier shooting equipment can be loaded.

[0047] For further information, please refer to Figure 5The adjusting link 433 is parallel to the adjusting screw 431. In the embodiment of the present application, two adjusting links 433 are provided. The adjusting links 433 are installed on the connecting portion 44. The connecting rod 423 has an opening for the adjusting link 433 to pass through, so that the adjusting link 433 and the connecting rod 423 can be slidably connected, thereby guiding the connecting rod 423 during its movement and increasing the stability of the connection.

[0048] Please refer to Figure 2 By rotating the adjusting knob 432, the connecting rod 423 and the buffer assembly 3 are driven to move along the axis direction of the adjusting screw 431, so as to change the relative angle between the buffer assembly 3 and the shock absorbing main arm 1. The larger the angle, the greater the upward component force, so that heavier shooting equipment can be loaded.

[0049] Please refer to Figure 2 The buffer assembly 3 includes an elastic member 31 and a damping member 32. In the embodiment of the present application, the elastic member 31 adopts a buffer spring, and the damping member 32 adopts a damper. The fixed end of the damper is rotatably connected to the front end of the shock absorbing main arm 1, and the free end of the damper, that is, one end of the piston rod, is rotatably mounted on the second connecting member 42; the buffer spring is sleeved on the damper, and the elastic member 31 is extended or compressed as the damping member 32 is extended or compressed, thereby achieving buffer shock absorption.

[0050] For further information, please refer to Figure 2 A force regulator 33 is sleeved on the damping member 32, and the force regulator 33 is adjustably installed on the damper. A retaining ring 34 is provided at one end of the damper close to the second connecting member 42. One end of the buffer spring abuts or is directly connected to the retaining ring 34, and the other end abuts or is directly connected to the force regulator 33. The force regulator 33 adjusts its position on the damper to control the length of the buffer spring, thereby adjusting the deformation of the elastic member 31. The shock absorbing arm can carry different load-bearing shooting equipment, and the shock absorbing force and rebound speed can be quickly adjusted according to the weight of the camera. When the shock absorbing device needs to adapt to machines of different weights, there is no need to replace the spring, and it has higher applicability.

[0051] In the embodiment of the present application, the force adjuster 33 is threadedly connected to the damper, and the moving direction of the force adjuster 33 is distributed along the length direction of the piston rod of the damper; the specific position of the force adjuster 33 can be debugged according to the weight-bearing shooting equipment carried during actual shooting, so as to determine the appropriate position of the force adjuster 33.

[0052] In another embodiment, please refer to Figure 6 A support assembly 5 is provided on the side of the base 2 away from the shock absorbing main arm 1. The support assembly 5 includes a support member 51, a positioning member 52 and a locking member 53. The support member 51 is used to connect the base 2 and support the shock absorbing arm. The support member 51 can be adjustably installed on the positioning member 52 through the locking member 53. The positioning member 52 is used to be fixed to the carrier.

[0053] For details, please refer to Figure 6 The positioning member 52 includes a shock-absorbing connecting frame 522, a carrier connecting frame 523 and a plurality of electric suction cups 521, wherein the support member 51 is set as a frame and is locked on the shock-absorbing connecting frame 522 through a locking member 53, and the shock-absorbing connecting frame 522 is provided with a plurality of interfaces for connecting with the support member 51, so as to facilitate adjustment of the installation position of the shock-absorbing arm. The shock-absorbing connecting frame 522 and the carrier connecting frame 523 are unlocked, adjusted and locked by setting a locking member 53; the electric suction cup 521 is connected to the shock-absorbing connecting frame 522 and the carrier connecting frame 523 through the locking member 53.

[0054] Specifically, in the embodiments of this application, please refer to Figure 6 and Figure 7 The locking member 53 includes a sliding portion 531, a clamping portion 532 and a locking portion 533. The sliding portion 531 is arranged at the end of the shock-absorbing connecting frame 522. The shock-absorbing connecting frame 522 is clamped and slidably installed on the carrier connecting frame 523 through the sliding portion 531. The clamping portions 532 are distributed on both sides of the carrier connecting frame 523 and are slidably arranged on the sliding portion 531. The locking portion 533 is arranged on the sliding portion 531 and is used to adjust the clamping portion 532 to move toward the side close to the carrier connecting frame 523 until the clamping portion 532 is clamped and fixed on the carrier connecting frame 523, thereby realizing the locking of the carrier connecting frame 523 and the shock-absorbing connecting frame 522. In a specific embodiment, the sliding portion 531 is configured as a sliding plate, and the sliding plate also has a card plate on both sides for buckling on the carrier connecting frame 523. The clamping portion 532 is configured as a clamping plate slidably installed at the position of the card plate. The locking portion 533 adopts a screw that is rotatably installed on the sliding portion 531 and threadedly connected to the clamping plate. The movement of the clamping plate is adjusted and the carrier connecting frame 523 is clamped by rotating the screw. In other embodiments, the locking member 53 can also adopt other locking structures that can achieve detachable connection; the position and number of the electric suction cup 521 are distributed and arranged according to the surface shape of the carrier, and the upper end of the electric suction cup 521 is installed on the shock-absorbing connecting frame 522 and the carrier connecting frame 523 through the locking member 53, and the lower end of the electric suction cup 521 is adsorbed on the surface of the carrier. Specifically, the support member 51 can also be locked on the shock-absorbing connecting frame 522 through the locking member 53. The locking principle is the same as in this paragraph, so it will not be discussed in detail.
