[0030] It should be noted that electronic equipment includes but is not limited to photographic equipment and electronic display equipment.

[0031] refer to Figure 1 The support frame 10 includes a gimbal 100 and a tripod 200. The gimbal 100 is used to install photographic equipment. The tripod 200 is connected to the gimbal 100, and the tripod 200 can support the gimbal 100 on a supporting surface to support the photographic equipment at a suitable height, so that the user can use the photographic equipment to shoot or live broadcast.

[0032] It should be noted that photographic equipment refers to cameras, mobile phones and other shooting equipment.

[0033] It should be noted that the support surface is the position where the support frame 10 is fixed, and the support surface includes but is not limited to support positions such as a desktop and a countertop.

[0034] refer to Figure 1 and Figure 2 The tripod 200 includes a plurality of legs 210 extending at an angle, and the plurality of legs 210 extending at an angle support the pan / tilt 100 on the support surface. Whether the plurality of legs 210 extending at an angle can be folded to form a gripping handle of the tripod 200 is not within the scope of consideration of the present application.

[0035] refer to Figure 2 It should be noted that, in this embodiment, the number of legs 210 is set to three. It can be understood that in other embodiments, the number of legs 210 can also be set to four, five, etc. As long as multiple legs 210 are spread out at an angle and can support the gimbal 100 on the supporting surface, all solutions should be protected.

[0036] refer to Figure 1 and Figure 2 , wherein the outer surface of at least one leg 210 is provided with a first clamping assembly 211, and the first clamping assembly 211 includes a first clamping block 212 and a second clamping block 213 which can be relatively close to and relatively far away from each other, and the first clamping block 212 and the second clamping block 213 clamp the electronic display device.

[0037] It should be noted that the electronic display device is a device such as a mobile phone or a teleprompter that can display the script.

[0038] To summarize, in the present application, the support frame 10 includes a gimbal 100 and a tripod 200. A photographic device can be installed on the gimbal 100. The tripod 200 includes a plurality of legs 210. At least one leg 210 is provided with a first clamping assembly 211. The first clamping assembly 211 can clamp an electronic display device. When the user is broadcasting live, he only needs to prepare one support frame 10 to install two electronic devices at the same time, one electronic device is used for live broadcast, and the other electronic device is used for viewing scripts, thereby realizing a dual-camera setting of one support frame 10. There is no need to prepare an additional bracket or mobile phone clamp, and the operation is convenient.

[0039] refer to Figure 1 and Figure 2 , the leg 210 provided with the first clamping assembly 211 is defined as the first leg 214, and the other legs are defined as the second legs 215. It should be noted that, in this embodiment, the number of the first legs 214 is one, and the number of the second legs 215 is set to two.

[0040] refer to Figure 1 and Figure 2 It should be noted that the second leg 215 is rotatably connected to the first leg 214 or the pan / tilt head 100 so that the leg 210 can be switched between the closed state and the open state. Figure 1 In the closed state, the second leg 215 is attached to the side wall of the first leg 214, and the support frame 10 can be stored, the storage volume is small, and it is convenient to carry; refer to Figure 2 In the open state, the support frame 10 can be placed on a support surface and used in conjunction with an electronic device.

[0041] refer to Figure 1 and Figure 2 The first clamping assembly 211 further includes a rotating block 216, which is rotatably connected to the first leg 214, and the opposite ends of the rotating block 216 are respectively connected to the first clamping block 212 and the second clamping block 213. The first clamping block 212, the second clamping block 213 and the rotating block 216 form a clamping space 217, and the electronic display device is clamped in the clamping space 217. When the electronic display device is clamped in the clamping space 217, the rotating block 216 is rotated, and the first clamping assembly 211 can rotate relative to the first leg 214, so that the electronic display device switches between the horizontal screen and the vertical screen, which increases the use state of the electronic display device installed on the support frame 10 and can adapt to more use scenarios.

[0042] refer to Figure 2 and Figure 3 It should be noted that the first clamping component 211 is used in conjunction with the electronic device. At this time, the support frame 10 is equivalent to the electronic device bracket. The user can use the support frame 10 to watch short videos, chat with others, etc. in the horizontal screen state (refer to Figure 3 ), or watch movies, TV series, etc. in vertical mode (reference Figure 2 ), users can effectively avoid problems such as hand discomfort caused by holding the electronic device for a long time, and the electronic device can also be adjusted to a comfortable viewing angle, allowing users to watch the electronic device comfortably for a long time.

[0043] refer to Figure 1 and Figure 2It should be noted that the first clamping assembly 211 has a clamping state and a storage state. In the clamping state, the first clamping block 212, the second clamping block 213 and the rotating block 216 form the above-mentioned clamping space 217; the first clamping block 212 and the second clamping block 213 can be flipped toward each other relative to the first leg 214 to switch the first clamping assembly 211 to the storage state; in the storage state, the first clamping assembly 211 is in a rectangular block shape and can be stacked on the first leg 214, and the flipped first clamping block 212 and the flipped second clamping block 213 abut against both sides of the rotating block 216. By setting the flipped first clamping block 212 and the flipped second clamping block 213 to abut against the opposite sides of the rotating block 216, the outer surface of the first clamping block 212, the outer surface of the second clamping block 213 and the outer surface of the rotating block 216 are all flush, which can reduce the volume of the first clamping assembly 211 in the storage state, reduce the volume of the entire support frame 10, and facilitate storage. It is understandable that the flipped first clamp block 212 and the flipped second clamp block 213 can also be set not to abut against the opposite sides of the rotating block 216. As long as the first clamp block 212 and the second clamp block 213 clamp the electronic display device, they should be protected.

[0044] It should be noted that in other embodiments, the flipped first clamp 212 and the flipped second clamp 213 are docked with each other, so that the outer surface of the first clamp 212 is flush with the outer surface of the second clamp 213, reducing the storage volume of the support frame 10.

[0045] refer to Figure 1 and Figure 2The outer surface of the first leg 214 is provided with a notch groove 218, and the first clamping component 211 is at least partially received in the notch groove 218. The notch groove 218 has a first groove wall 219 and a second groove wall 220 in the length direction of the first leg 214, and the notch groove 218 has a first opening 221 and a second opening 222 in the width direction of the first leg 214. When the first clamping component 211 is in the received state, the outer surface of the first clamp block 212 and the outer surface of the second clamp block 213 are flush with the outer surface of the first leg 214, and the side surfaces of the first clamp block 212 and the side surfaces of the second clamp block 213 are flush with the side surfaces of the first leg 214. When the first clamping assembly 211 is in the clamping state, the first clamping block 212 is opposite to and spaced from the first groove wall 219, and there is a rotation space between the first clamping block 212 and the first groove wall 219, and the second clamping block 213 is opposite to and spaced from the second groove wall 220, and there is a rotation space between the second clamping block 213 and the second groove wall 220; under the action of external force, the first clamping block 212 and the second clamping block 213 rotate to the outside of the notch groove 218 through the first opening 221 and the second opening 222, so that the electronic display device switches from the horizontal screen to the vertical screen state. By setting the notch groove 218, the first clamping assembly 211 in the storage state is completely accommodated in the notch groove 218, reducing the storage volume of the support frame 10 and facilitating the user to move the support frame 10. It should be noted that in the case where the first clamping assembly 211 cannot rotate relative to the first leg 214 to switch between the horizontal screen and the vertical screen, the notch groove 218 may not be set, and the scheme that the first clamping assembly 211 is set on the outer surface of the first leg 214 should be protected.

[0046] refer to Figure 1 and Figure 2The second clamping block 213 includes a sliding block 223 and a clamping block 224. The opposite ends of the sliding block 223 are respectively connected to the rotating block 216 and the clamping block 224. The sliding block 223 can move relative to the rotating block 216 and the first clamping block 212. The clamping block 224 is rotatably connected to the sliding block 223 to achieve flipping. The first clamping block 212 is rotatably connected to the rotating block 216 to achieve flipping. By setting the first clamping assembly 211 to include the first clamping block 212, the rotating block 216, the sliding block 223 and the clamping block 224, the rotating block 216 is rotatably connected to the first leg 214, so that the first clamping assembly 211 can rotate relative to the first leg 214 to switch between the horizontal screen state and the vertical screen state. The sliding block 223 can move relative to the rotating block 216 to adjust the distance between the first clamping block 212 and the clamping block 224. The user can adjust the distance between the first clamping block 212 and the clamping block 224 according to the size of different types of electronic devices. The first clamping assembly 211 can install electronic devices of different models, which increases the compatibility of the support frame 10 with the electronic device. The first clamping block 212 can rotate relative to the rotating block 216, and the clamping block 224 can rotate relative to the sliding block 223, so that the first clamping block 212 and the clamping block 224 can rotate into the notch groove 218, thereby reducing the storage volume of the first clamping assembly 211.

[0047] refer to Figure 2 It should be noted that a step 225 is formed on the side of the rotating block 216 close to the first clamping block 212, and a step 225 is also formed between the rotating block 216 and the sliding block 223. When the first clamping assembly 211 is in the storage state, the first clamping block 212 and the clamping block 224 overlap on the two steps 225, and the outer surface of the first clamping block 212, the outer surface of the clamping block 224 and the outer surface of the first leg 214 are flush, reducing the storage space. It can be understood that the two steps 225 may not be set, as long as the first clamping block 212 and the clamping block 224 can clamp the electronic device, all solutions should be protected.

[0048] It should be noted that when the first clamping assembly 211 is in the storage state, the first clamping block 212 abuts against the first groove wall 219, and the second clamping block 213 and the second groove wall 220 are enclosed to form a slot. It should be noted that the slot includes but is not limited to a dovetail slot, a semi-dovetail slot, such as Figure 1 As shown, the slot is a half dovetail slot 226 .

[0049] It should be noted that, in other embodiments, when the first clamping assembly 211 is in the storage state, the first clamping block 212 and the first groove wall 219 are combined to form a slot, and the second clamping block 213 and the second groove wall 220 are combined to form a slot.

[0050] It should be noted that, in other embodiments, when the first clamping assembly 211 is in the storage state, the first clamping block 212 and the first groove wall 219 are combined to form a slot, and the second clamping block 213 and the second groove wall 220 are butted against each other.

[0051] It should be noted that, in other embodiments, when the first clamping assembly 211 is in the storage state, the first clamping block 212 abuts against the first groove wall 219 , and the second clamping block 213 abuts against the second groove wall 220 .

[0052] refer to Figure 2 and Figure 3 The pan / tilt head 100 includes an adapter 110 and a second clamping assembly 120 . The second clamping assembly 120 is connected to the adapter 110 , and the photographic device is clamped by the second clamping assembly 120 .

[0053] refer to Figure 2 and Figure 3 The second clamping assembly 120 includes a first clamping member 121, a second clamping member 122, a threaded connection member 123 and an elastic member 124. The first clamping member 121 and the second clamping member 122 can be close to or away from each other, and can clamp the photographic equipment between the first clamping member 121 and the second clamping member 122. The threaded connection member 123 is penetrated through the first clamping member 121 and is threadedly connected to the second clamping member 122. The opposite ends of the elastic member 124 are respectively abutted against the first clamping member 121 and the second clamping member 122. When the second clamping member 122 moves away from the first clamping member 121 under the action of external force, the elastic member 124 is stretched to accumulate elastic force. After the user places the photographic equipment between the first clamping member 121 and the second clamping member 122 and releases the external force acting on the second clamping member 122, the elastic force is released, and the elastic member 124 drives the second clamping member 122 to move closer to the first clamping member 121 and clamps the photographic equipment between the first clamping member 121 and the second clamping member 122.

[0054] refer to Figure 2 At least one of the first clamping member 121 and the second clamping member 122 is provided with a cold shoe slot 125, and the cold shoe slot 125 can be externally connected to a microphone, a fill light, or other equipment with a cold shoe block, thereby enriching product functions and shooting effects.

[0055] It should be noted that when the support frame 10 is installed with the second clamping assembly 120, the photographic device can be clamped in the second clamping assembly 120. At this time, the user can use the support frame 10 for live broadcasting, and can connect an external microphone or fill light according to the use environment. The first clamping assembly 211 is installed with an electronic display device. The user can use the photographic device for live broadcasting while watching the script displayed on the electronic display device.
