Detailed implementation manners

[0042] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention.

[0043] Generally, the components of the embodiments of the present invention described and shown in the drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the claimed invention, but merely represents the selected embodiments of the present invention.

[0044] Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the scope of protection of the present invention.

[0045] In the description of the present invention, it should be noted that the orientation or positional relationship indicated by the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings. These are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present invention. In addition, the terms "first", "second", "third" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance.

[0046] In the description of the present invention, it should be noted that unless otherwise clearly specified and limited, the terms "mounted", "connected", "coupled" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0047] See Figures 1 to 21 As shown, an embodiment of the present invention provides a support frame, which includes a first pan-tilt connecting member 104 and a leg assembly connected to the first pan-tilt connecting member 104; the leg assembly includes a main leg 101 and a secondary leg; a leg adjustment structure is provided between the main leg 101 and the secondary leg for unlocking or locking between the main leg 101 and the secondary leg, so that relative movement or relative rest can be achieved between the main leg 101 and the secondary leg; the secondary leg may include a first sub-leg 102 and a second sub-leg 103, and the first sub-leg 102 and the second sub-leg 103 can be unfolded or folded together; when the first sub-leg 102 and the second sub-leg 103 are unfolded, the main leg 101, the first sub-leg 102, and the second sub-leg 103 can form a three-legged support state.

[0048] The relative movement between the main leg 101 and the secondary leg may refer to actions such as the main leg 101 rotating or folding relative to the secondary leg, so that the angle formed between the length direction of the main leg 101 and the length direction of the secondary leg can be adjusted, that is, the opening angle between the main leg 101 and the secondary leg can be adjusted; and the leg adjustment structure has the functions of unlocking and locking. That is, after unlocking, the opening angle between the main leg 101 and the secondary leg can be adjusted as needed. After obtaining the required angle, the required angle between the main leg 101 and the secondary leg is maintained through the locking function, that is, the required angle remains unchanged. The main leg 101 can be folded together with the secondary leg, which is beneficial to the storage of the support frame and reduces the space occupied by the support frame.

[0049] The first sub-foot 102 and the second sub-foot 103 can be unfolded or folded by relative rotation or flipping and other actions. When the first sub-foot 102 and the second sub-foot 103 are folded together, it is beneficial to the storage of the support frame and reduces the space occupied by the support frame. After the opening angle between the main support foot 101 and the secondary support foot is adjusted, through the unfolding between the first sub-foot 102 and the second sub-foot 103, the main support foot 101, the first sub-foot 102 and the second sub-foot 103 form a common three-foot support state, which can realize the support of the image acquisition device 200.

[0050] When the image acquisition device 200 is provided with an interface structure that matches the first pan-tilt connection member 104 in this embodiment, the image acquisition device 200 can be directly mounted on the first pan-tilt connection member 104. When the image acquisition device 200 does not have an interface structure that matches the first pan-tilt connection member 104, it can be mounted on the first pan-tilt connection member 104 in an indirect manner, that is, an indirect mounting structure is adopted. For example, the image acquisition device 200 can be mounted on the first pan-tilt connection member 104 through a quick-release plate, a pan-tilt or a mounting clip and other adoptable mounting structures.

[0051] It should be noted that the number of sub-feet of the secondary support foot is not limited to two, that is, including the first sub-foot 102 and the second sub-foot 103. The number of sub-feet of the secondary support foot can also be three, four, five or more.

[0052] The support frame provided by the embodiment of the present invention can conveniently unlock and lock between the main support foot 101 and the secondary support foot through the foot adjustment structure; and the secondary support foot includes the first sub-foot 102 and the second sub-foot 103, and can be unfolded or folded. In this way, three feet can be used to achieve three-foot support. Thus, when holding for a long time, the first sub-foot 102 and the second sub-foot 103 can be unfolded, so that the hands can be liberated by using the three-foot support, and the use functions of the support frame can be diversified.

[0053] In an optional solution of this embodiment, one end of the main support foot 101, one end of the first sub-foot 102 and one end of the second sub-foot 103 are connected to form an end connection position; the first pan-tilt connection member 104 is arranged at the end connection position. The end connection position can refer to the spatial position of the first pan-tilt connection member 104 on the support frame. The support frame can further include a second pan-tilt connection member 105, and the second pan-tilt connection member 105 is arranged on the main support foot 101. The second pan-tilt connection member 105 can be arranged in the middle of the main support foot 101, at the other end of the main support foot 101 or at a position close to the other end of the main support foot 101. Through the second pan-tilt connection member 105, the image acquisition device 200 can be mounted at different positions on the support frame to meet different usage requirements.

[0054] It should be noted that in this embodiment, the first pan-tilt connecting member 104 can be arranged on the main support leg 101, and the second pan-tilt connecting member 105 is arranged at the end connection position formed after one end of the main support leg 101, one end of the first sub-leg 102, and one end of the second sub-leg 103 are connected.

[0055] In an alternative solution of this embodiment, the support frame further includes a stopper 106, and at least the main support leg 101 is provided with the stopper 106 for enabling the support frame to be mounted on the host object 300. The support frame can be hung on the host object 300 through the stopper 106. In this way, on the one hand, it can free the hands, and on the other hand, it can meet different shooting requirements. The host object 300 can be a wall, a board, a shelf, or any other structure that is convenient for hanging the support frame, and enables the support frame to form a stable state, so as to avoid the image acquisition device 200 shaking or the support frame falling off the host object 300 due to the instability of the support frame.

[0056] It should be noted that the stopper 106 can also be arranged on at least one of the first sub-leg 102 and the second sub-leg 103 to facilitate the support frame to be mounted on the host object 300.

[0057] In an alternative solution of this embodiment, the support frame further includes a pan-tilt adjustment structure for adjusting the rotation angle of the first pan-tilt connecting member 104 relative to the main support leg 101. The pan-tilt adjustment structure is beneficial to realizing the rotation angle of the first pan-tilt connecting member 104, such as adjusting the pitch angle, so as to meet the shooting requirements, such as shooting from below, shooting from above, or shooting horizontally. It should be noted that when the placement direction of the support frame changes, the pitch angle may be converted into an azimuth angle, or may be converted into other states, but still changes the rotation angle of the first pan-tilt connecting member 104.

[0058] In an alternative solution of this embodiment, the pan-tilt adjustment structure includes a first button 107, a first sprocket 108, a second sprocket 109, and a first elastic member 110; the first sprocket 108 is fixedly connected to the first pan-tilt connecting member 104, and the first elastic member 110 is used to enable the teeth on the second sprocket 109 to mesh with the teeth on the first sprocket 108; the first button 107 is used to overcome the elastic force of the first elastic member 110 under the action of an external force, so that the teeth on the second sprocket 109 are separated from the teeth on the first sprocket 108.

[0059] The first sprocket 108 and the first pan-tilt connecting member 104 can be of an integral structure, which can ensure the safety and stability of the external device on the first pan-tilt connecting member 104, such as the image acquisition device 200, during use. The first elastic member 110 can be a spring. By applying a force to the second sprocket 109 through the first elastic member 110, the teeth on the second sprocket 109 can be engaged with the teeth on the first sprocket 108. The number of teeth on the first sprocket 108 and the second sprocket 109 is multiple, and the multiple teeth can be circularly distributed, that is, the multiple teeth enclose a circle. During use, the user presses the first button 107, so that the first button 107 can move along the first direction against the elastic force of the first elastic member 110, so that the first elastic member 110 is compressed, and finally the teeth on the second sprocket 109 are no longer engaged with the teeth on the second sprocket 109. At this time, the rotation angle of the first pan-tilt connecting member 104 can be adjusted. When the external force is removed, that is, when the user no longer applies force to the first button 107, the elastic potential energy of the uncompressed first elastic member 110 is released, so that the second sprocket 109 moves in the direction of the first sprocket 108, so that the teeth on the second sprocket 109 are engaged with the teeth on the first sprocket 108, locking the first pan-tilt connecting member 104 so that it cannot rotate freely.

[0060] In an alternative solution of this embodiment, the support frame further includes a first adapter 112 and a second adapter 113. The first adapter 112 is connected to the secondary support leg, and the second adapter 113 is fixedly connected to the main support leg 101. The first sprocket 108 and the second sprocket 109 are both located between the second adapter 113 and the first adapter 112, wherein the second sprocket 109 is located between the first sprocket 108 and the second adapter 113. By providing the first adapter 112 and the second adapter 113, it is convenient to realize the relative rotation between the main support leg 101 and the secondary support leg.

[0061] In an alternative solution of this embodiment, the first pan-tilt connecting member 104 is fixedly connected to the outer peripheral surface of the first sprocket 108.

[0062] In an alternative solution of this embodiment, the first button 107 includes a key cap 114 and a key stem 115. One end of the key stem 115 is connected to the key cap 114. The first adapter 112 has a jack 116 for the key stem 115 to pass through, and the other end of the key stem 115 abuts against the disk surface of the second sprocket 109. The key cap 114 is convenient to be pressed by fingers. When pressing the key cap 114, the key stem 115 can move the second sprocket 109, so that the teeth on the second sprocket 109 are separated from the teeth on the first sprocket 108.

[0063] The keycap 114 can be circular, polygonal, etc.; the number of the key stems 115 is two, the radial cross-section of the key stem 115 is arc-shaped, and the radial direction of the key stem 115 is parallel to the radial direction of the keycap 114. The jack 116 on the first adapter 112 can be arc-shaped to be adapted to the key stem 115; the two key stems 115 are symmetrically arranged on one side of the keycap 114. Optionally, the other end of the key stem 115 has a first protrusion 117, and the first protrusion 117 extends along the radial direction of the key stem 115 for limiting the key stem 115 on the first adapter 112; and the key stem 115 has a certain elasticity. When assembling the key stem 115 on the first adapter 112, pinch the two key stems 115, and make the key stems 115 pass through their respective corresponding jacks 116 respectively, and make the first protrusion 117 also pass through the first jack 116. After passing through, release the two key stems 115, and the key stem 115 returns to its original state under the action of elasticity, and the first protrusion 117 then plays a stop role to prevent the key stem 115 from disengaging from the first adapter 112. By providing two key stems 115 and two jacks 116, the movement of the first button 107 can also be guided to prevent the first button 107 from rotating around the axis parallel to the first direction.

[0064] In an optional solution of this embodiment, the teeth on the second sprocket 109 are located on one side of the second sprocket 109, and a guide post 118 is provided on the opposite side of the second sprocket 109; a guide groove 119 that cooperates with the guide post 118 is provided on one side of the second adapter 113 for guiding the axial movement of the second sprocket 109. The guide post 118 and the guide groove can prevent the second sprocket 109 from rotating relative to the second adapter 113, that is, the circumferential fixation of the two is achieved.

[0065] The pan-tilt adjusting structure further includes a first nylon gasket 120, a second nylon gasket 121, a check screw 122, a bushing 123, a locking screw 124, and a sleeve 125; both the first nylon gasket 120 and the second nylon gasket 121 are annular; the first nylon gasket 120 is located between the first adapter 112 and the first chainring 108, that is, the two opposite surfaces of the first nylon gasket 120 are respectively in contact with the first adapter 112 and the first chainring 108; the second adapter 113 has a shaft hole 126, and the guide groove is opened on the inner wall of the shaft hole 126. The maximum outer diameter of the second chainring 109 is smaller than the inner diameter of the shaft hole 126, so that the second chainring 109 can move in the shaft hole 126. The inner ring diameter of the second nylon gasket 121 is larger than the maximum outer diameter of the second chainring 109. The second nylon gasket 121 is sandwiched between the first chainring 108 and the second adapter 113, that is, the two opposite surfaces of the second nylon gasket 121 are respectively in contact with the first chainring 108 and the second adapter 113; by providing the first nylon gasket 120 and the second nylon gasket 121, when the first chainring 108 drives the first pan-tilt connecting member 104 to rotate, there is a certain damping force. One end of the sleeve 125 has a stop cap 127. After the other end of the sleeve 125 is inserted through the mounting through hole on the second adapter 113 and then passes through the mounting through hole on the second chainring 109, it is inserted into the positioning shaft 128 provided on one surface of the first adapter 112. The inner wall of the hole of the sleeve 125 has an anti-rotation groove 129, and the positioning shaft 128 is provided with an anti-rotation protrusion 130. The anti-rotation protrusion 130 cooperates with the anti-rotation groove 129. When the sleeve 125 is inserted into the positioning shaft 128 on the first adapter 112, the relative rotation between the sleeve 125 and the first adapter 112 is prevented by the anti-rotation protrusion 130 and the anti-rotation groove 129. The external thread of the bushing 123 is threadedly connected to the threaded hole on the first adapter 112; the locking screw 124 passes through the sleeve hole of the sleeve 125 and is threadedly connected to the internal thread of the bushing 123, and the check screw 122 is threadedly connected to the threaded hole at the end of the locking screw 124. The stop cap 127 of the sleeve 125 can be in contact with one surface of the second adapter. The check screw 122 can prevent the locking screw 124 from coming out of the sleeve 125; through the locking screw 124, the sleeve 125, the bushing 123, and the check screw 122, the first adapter 112 and the second adapter 113 are connected together, and the second adapter 113 can rotate relative to the first adapter 112. The first direction is parallel to the axial direction of the sleeve 125. One end of the first elastic member 110 abuts against the bottom of the shaft hole 126, and the other end of the first elastic member 110 abuts against the surface of the second chainring 109 having the guide post 118.It should be noted that the screw sleeve 123 can also be an integral structure with the first adapter 112, that is, a threaded hole matching the external thread of the locking screw 124 is provided on the first adapter; in addition, for the method of preventing the locking screw 124 from coming out of the shaft sleeve 125, it is not limited to the check screw, and other fasteners can also be used to achieve this. The fastener can be a circlip (i.e., a retaining ring) or a pin, and the pin can be a split pin; when using a circlip, an anti-loosening groove can be circumferentially provided at the end of the locking screw. After the end of the locking screw provided with the anti-loosening groove extends out of the screw sleeve 123, the circlip is then snapped into the anti-loosening groove, which can prevent the locking screw from coming out; when using a pin, a radial through hole can be provided at the end of the locking screw. After the end of the locking screw provided with the radial through hole extends out of the screw sleeve 123, the pin is then inserted into the radial through hole, which can prevent the locking screw from coming out.

[0066] In an optional solution of this embodiment, the first adapter 112 can be a component of the support leg adjustment structure; the first adapter 112 includes a first barrel ring 131 and an insertion shaft 132 fixedly connected to the outer peripheral surface of the first barrel ring 131; the insertion shaft 132 is inserted and connected with the damping shaft 133, and is circumferentially fixed between the insertion shaft 132 and the damping shaft 133; a plurality of positioning grooves 134 are distributed along the circumferential direction of the outer peripheral surface of the first barrel ring 131. A second button can be indirectly or directly installed on the second adapter 113. For example, the second button is installed on the main support leg 101, so that the second button is indirectly installed on the second adapter 113. The main support leg 101 is provided with a second button, and the second button can be limited in different positioning grooves 134 to adjust the opening angle between the main support leg 101 and the secondary support leg, that is, to adjust the rotation angle of the second adapter 113 relative to the first adapter 112.

[0067] It should be noted that the second button can also be installed on other structures connected to the second adapter 113.

[0068] The first adapter 112 can also include a bottom support 136 with an arc-shaped curved surface 135. The arc-shaped curved surface 135 is located on the upper surface of the bottom support 136, and the first barrel ring 131 is fixed on the upper surface of the bottom support 136. The insertion shaft 132 is fixed on the lower surface of the bottom support 136, that is, the insertion shaft 132 is fixedly connected to the first barrel ring 131 through the bottom support 136. The arc-shaped curved surface 135 can be adapted to the circular outer peripheral surface of the first chainring 108 and the circular outer peripheral surface of the second adapter 113, and the arc-shaped curved surface 135 has a certain supporting effect on the first chainring 108 and the second adapter 113.

[0069] In an alternative solution of this embodiment, the number of positioning grooves 134 is at least three. The second button includes a first columnar portion 137 and a second columnar portion 138 connected to the first columnar portion 137. The axis of the first columnar portion 137 is perpendicular to the axis of the second columnar portion 138. The first columnar portion 137 abuts against the return elastic member 139. When the first columnar portion 137 is pressed, the second column portion can be disengaged from the positioning groove 134, so that the second adapter 113 can rotate relative to the first adapter 112.

[0070] The main support leg 101 is provided with a button hole 140 and a side hole 141. The side hole 141 is opened on the hole wall of the button hole 140. The axial direction of the side hole 141 is perpendicular to the axial direction of the button hole 140. The first columnar portion 137 is inserted into the button hole 140, and the second columnar portion 138 is inserted into the side hole 141. Since the second columnar portion 138 is inserted into the side hole 141 and the second columnar portion 138 is connected to the first columnar portion 137, the first columnar portion 137 will not be disengaged from the button hole 140. The return elastic member 139 can be a spring. The return elastic member 139 is installed in the button hole 140 and abuts against one end of the first columnar portion 137. The side hole 141 can be an oval hole or a strip hole. In this way, when the first columnar portion 137 is pressed, the second columnar portion 138 can move along the radial direction of the oval hole or the strip hole, which is beneficial to the end of the second column portion inserted into the positioning groove 134 to be disengaged from the positioning groove 134. The first columnar portion 137 can be threadedly connected to the second columnar portion 138. When three positioning grooves 134 are provided, three angular changes can be achieved between the main support leg 101 and the secondary support leg.

[0071] It should be noted that the number of positioning grooves 134 can also be 2, 4, 5 or more to meet the requirements of different occasions.

[0072] In an alternative solution of this embodiment, the main support leg 101 is fixedly connected to the second adapter 113, and the two can be an integral structure. After unlocking through the second button, the end of the second column portion is disengaged from the positioning groove 134, so that the second adapter 113 can rotate relative to the first adapter 112 to adjust the opening angle between the main support leg 101 and the secondary support leg.

[0073] In an alternative embodiment of this example, the support frame further includes a shield 142. The length extension direction of the shield 142 is arc-shaped to match the outer peripheral surface of the first cylinder ring 131. The shield 142 can cover the plurality of positioning grooves 134 to prevent foreign objects from entering. One end of the shield 142 has a convex portion 143, while the end surface of one end of the main support leg 101 has a concave portion 144. The convex portion 143 is inserted into the concave portion 144. The lower surface of the first pan-tilt connecting member 104 has an arc surface 145. The shield 142 is limited between the outer peripheral surface of the first cylinder ring 131 and the arc surface 145 of the lower surface of the first pan-tilt connecting member 104, which can prevent the shield 142 from coming off the support frame. When the main support leg 101 rotates relative to the first adapter 112, it will drive the shield 142 to rotate around the outer peripheral surface of the first cylinder ring 131.

[0074] In an alternative embodiment of this example, an angle adjustment structure is provided between the first sub-leg 102 and the second sub-leg 103 to adjust the opening angle between the first sub-leg 102 and the second sub-leg 103. Through the angle adjustment structure, the opening or closing between the first sub-leg 102 and the second sub-leg 103 can be realized. After adjusting the opening angle, it is beneficial to maintain the required angle and prevent it from changing easily. The angle adjustment structure can form a fixed set angle after the first sub-leg and the second sub-leg are opened.

[0075] See Figure 9 、 Figure 11 、 Figure 12 、 Figure 13 and Figure 21 As shown in

[0076] One end of the first sub-leg 102 and one end of the second sub-leg 103 both have damping holes 147. First limiting ribs 165 extending along the axial direction of the damping holes 147 are provided on the inner wall of the damping holes 147. The damping shaft 133 passes through the damping holes 147 of the first sub-leg 102 and the damping holes 147 of the second sub-leg 103, and the first limiting ribs are limited in the first limiting grooves 146. A positioning card slot 166 is provided at the bottom of the first limiting groove, and the positioning card slot is close to the groove wall of the first limiting groove. Optionally, the number of the positioning card slots can be two, and the two positioning card slots are respectively located at two opposite groove walls of the first limiting groove. When the first sub-leg and the second sub-leg are fully opened to form a set angle, the first limiting ribs fall into the positioning card slots, which is beneficial to keeping the set angle formed between the first sub-leg and the second sub-leg from changing easily. It should be noted that the material of the damping shaft can be plastic, rubber or silica gel, which enables the damping shaft to undergo a certain deformation, thus being beneficial to the stability of the angle between the two sub-legs after the first limiting ribs fall into the positioning card slots.

[0077] The damping shaft 133 may have a splined hole, and the outer surface of the inserted shaft 132 may have external splines. After the inserted shaft 132 is inserted into the splined hole of the damping shaft 133, the external splines on the inserted shaft 132 cooperate with the internal splines in the splined hole, so as to achieve circumferential fixation between the damping shaft 133 and the inserted shaft 132. One end of the first sub-foot 102 and one end of the second sub-foot 103 both have a disc-shaped structure 148, and the damping hole 147 is formed in the disc-shaped structure 148; the disc-shaped structure 148 of the first sub-foot 102 is located between the disc-shaped structure 148 of the second sub-foot 103 and the base 136.

[0078] The axial direction of the inserted shaft 132 is perpendicular to the axial direction of the bushing 125, which is beneficial to making the rotation axis of the main support foot 101 relative to the secondary support foot perpendicular to the rotation axis of the first support foot relative to the second support foot, so as to facilitate the realization of three-legged support. When in three-legged support, taking the position where the support frame is placed as the ground for example, when in three-legged support, the rotation axis of the main support foot 101 relative to the secondary support foot can be parallel to the ground, and the rotation axis of the first support foot relative to the second support foot is perpendicular to the ground. In this way, when the angle between the main support foot 101 and the secondary support foot is locked by the foot adjustment structure, the force exerted by the image acquisition device 200 placed on the first pan-tilt connection member 104 on the support frame is a downward force. Since the rotation axis of the first support foot relative to the second support foot is perpendicular to the ground, the first support foot and the second support foot are not likely to rotate relative to each other, thus ensuring the stability and safety of the image acquisition device 200 during use; in addition, the rotation axis of the main support foot 101 relative to the secondary support foot is perpendicular to the rotation axis of the first support foot relative to the second support foot, which is also beneficial to the realization of the extended hand-held mode.

[0079] The angle adjustment structure may further include a third nylon gasket 149, a fourth nylon gasket 150, a bottom cover 151 and a flat head screw 152. The third nylon gasket 149 is located between the disc-shaped structure 148 of the first sub-foot 102 and the bottom bracket 136, so that when the first sub-foot 102 rotates, there is a certain damping force; the fourth nylon gasket 150 is located between the disc-shaped structure 148 of the second sub-foot 103 and the disc-shaped structure 148 of the first sub-foot 102, so that when the first sub-foot 102 and the second sub-foot 103 rotate, there is a certain damping force. The bottom cover 151 is fixedly connected to the insertion shaft 132 through the flat head screw 152, and the bottom cover 151 has a concave hole 153, and the concave hole 153 has an internal spline that matches the external spline on the outer surface of the insertion shaft 132, so as to prevent the bottom cover 151 from rotating with the second sub-foot 103 and causing the flat head screw 152 to loosen. The bottom cover 151 can prevent the first sub-foot 102 and the second sub-foot 103 from disengaging from the insertion shaft 132. The disc surface of the disc-shaped structure 148 of the first sub-foot 102 is arranged at an angle with the length extension direction of the first sub-foot 102, and the disc surface of the disc-shaped structure 148 of the second sub-foot 103 is arranged at an angle with the length extension direction of the second sub-foot 103. After the main foot 101 and the secondary foot are folded together, it is beneficial to enable the image acquisition device 200 on the first pan-tilt connecting member 104 to better photograph the user or other scenes when the main foot 101 and the secondary foot are held by hand.

[0080] In an optional solution of this embodiment, a first insertion slot 154 is provided on the first pan-tilt connecting member 104. The insertion port of the first insertion slot 154 is provided with a first stop block 155, and the first stop block 155 is configured to be able to extend or retract under the elastic action of the second elastic member. The second elastic member can achieve the stability of the installation of the external device installed on the first pan-tilt connecting member 104 and prevent the external device from disengaging from the first insertion slot 154. Similarly, a second insertion slot 159 is provided on the second pan-tilt connecting member 105. The insertion port of the second insertion slot 159 is provided with a second stop block 164, and the second stop block 164 is configured to be able to extend or retract under the elastic action of the third elastic member. The third elastic member can achieve the stability of the installation of the external device installed on the second pan-tilt connecting member 105 and prevent the external device from disengaging from the second insertion slot 159. Both the first insertion slot 154 and the second insertion slot 159 can be dovetail slots or wedge-shaped slots that can achieve the same function. The second elastic member and the third elastic member can both be springs.

[0081] One end of the first stopper 155 is rotatably connected to the first pan-tilt connecting member 104 through the first pin shaft 156. The other end of the first stopper 155 can limit the second elastic member between the first stopper 155 and the bottom of the first insertion groove 154 through the second pin shaft 157. In this way, pressing the other end of the first stopper 155 can cause the first stopper 155 to move downward to retract. When the first stopper 155 is released, the first stopper 155 can move upward to achieve the extended state and position the external device mounted on the first pan-tilt connecting member 104. The hole where the second pin shaft 157 is located is an oval hole, that is, the cross-section of the hole is oval. In this way, when pressing down the first stopper 155, the second pin shaft 157 can move radially along the oval hole.

[0082] One end of the second stopper 164 is rotatably connected to the second pan-tilt connecting member 105 through the third pin shaft. The other end of the second stopper 164 can limit the second elastic member between the second stopper 164 and the bottom of the second insertion groove 159 through the stopper portion. In this way, pressing the other end of the second stopper 164 can cause the second stopper 164 to move downward to retract. When the second stopper 164 is released, the second stopper 164 can move upward to achieve the extended state and position the external device mounted on the second pan-tilt connecting member 105. A foot cover 160 can be installed at the second insertion groove 159. In this way, when the second pan-tilt connecting member 105 is not in use, the foot cover 160 can be detachably connected to the second insertion groove 159 by snapping.

[0083] In an optional solution of this embodiment, the stopper 106 is disposed at the opposite end of the main support leg 101, and the stopper 106 can rotate relative to the main support leg 101 to cooperate with the main support leg 101 to form a hook structure.

[0084] The stopper 106 is rotatably mounted at one end of the main foot 101 through the fifth pin shaft 162; there is a sunk groove 163 on the main foot 101. The stopper 106 can rotate to be received in the sunk groove 163 and can also rotate to turn out from the sunk groove 163 to cooperate with the main foot 101 to form a hook structure. The stopper 106 can be in a plate-like structure. After the stopper 106 turns out from the sunk groove 163, the stopper 106 can be blocked by the groove wall of the sunk groove 163. In this way, the first angle formed by the length direction of the stopper 106 and the length direction of the main foot 101 is less than or equal to 90 degrees. Optionally, the first angle can be 60 degrees to 70 degrees. One end of the plate-like structure is hinged to the main foot 101, and a positioning block is provided on the plate surface at the other end of the plate-like structure; when the stopper 106 is received in the sunk groove 163, the positioning block faces the bottom of the sunk groove 163. A lever structure is provided on the end surface of the free end of the plate-like structure to facilitate the hand to pull out the plate-like structure from the sunk groove 163. The lever structure can be a groove structure or a handle. The first sub-foot 102 and the second sub-foot 103 can be closed, and the main foot 101 and the secondary foot can be closed. In this way, the main foot 101, the first sub-foot 102 and the second sub-foot 103 are closed together to form a whole foot. During use, the whole foot can be held by hand to achieve shooting. It should be noted that when a positioning block or other components capable of forming a hook structure with the plate-like structure are provided on the plate surface at the other end of the plate-like structure, the first angle formed by the length direction of the stopper 106 and the length direction of the main foot 101 can be greater than 90 degrees.

[0085] The support frame provided in this embodiment integrates the pan-tilt adjustment structure, the angle adjustment structure, and the foot adjustment structure, enabling the three to work independently or in cooperation to meet different usage requirements, so that the support frame has a handheld mode, a high-position three-legged support mode, a low-position three-legged support mode, an extended handheld mode, a hanging mode, etc.

[0086] I. Handheld mode (see Figure 14 shown)

[0087] By adjusting the angle adjustment structure and the foot adjustment structure, the main foot 101, the first foot, and the second foot are closed together, and the image acquisition device 200 can be installed on the first pan-tilt connection member 104. The user can hold the whole foot; to meet the pitching requirement of the image acquisition device 200, the pitching angle can be adjusted through the pan-tilt adjustment structure.

[0088] II. High-position three-legged support mode (see Figure 15 shown)

[0089] After a long-term hand-held mode or to achieve a three-legged support, the opening angle between the main support leg 101 and the secondary support leg can be adjusted by adjusting the support leg adjustment structure, and the opening angle between the first sub-leg 102 and the second sub-leg 103 can be adjusted by the angle adjustment structure, so that a high-position three-legged support mode can be achieved.

[0090] III. Low-position three-legged support mode (see Figure 16 shown)

[0091] When shooting at a position that requires a lower height, the opening angle between the main support leg 101 and the secondary support leg can be increased by adjusting the support leg adjustment structure, and at the same time, the opening angle between the first sub-leg 102 and the second sub-leg 103 can be increased by adjusting the angle adjustment structure. The low-position three-legged support mode has stronger stability and is also convenient for obtaining a low-position close-up view.

[0092] IV. Hanging mode (see Figure 17 and Figure 18 shown)

[0093] When using a three-legged support, the stopper 106 can be rotated out of the sunk groove 163, and the hook structure can be hung on a host object such as a plate-like object 300, so that a stable support structure formed by two sub-legs and a hook structure is realized, which can realize mounting and fixing the image acquisition device 200, meet the use in multiple environmental scenarios such as indoor or outdoor, and can realize photography in a narrow space.

[0094] V. Extended hand-held mode (see Figure 19 shown)

[0095] Install the image acquisition device 200 on the second pan-tilt connecting member 105, then adjust the opening angle between the main support leg 101 and the secondary leg through the support leg adjustment structure, and hold the secondary support leg by hand to achieve shooting; the opening angle between the main support leg 101 and the secondary support leg can be 140 degrees, which fully considers the shooting angle and the comfort of human body holding, and conforms to ergonomics. The extended hand-held mode can quickly obtain a wider scene view and greatly optimize the self-shooting experience.
