For example, the support assembly has a support base 110, and the support base 110 can be supported on a support surface 901. For example, the support base 110 includes at least three legs 112 that can be supported on the support surface 901. For example, the support base 110 includes a support plate that can be supported on the support surface 901.

[0085] For example, the support component can be attached to the attachment surface. For example, the support component has a first magnetic portion, and the first magnetic portion can be magnetically attracted to the attachment surface. For another example, the support component has a first suction cup, and the first suction cup can be adsorbed on the attachment surface.

[0086] For example, the support assembly can be clamped on a clamped object. For example, the support assembly has a clamp that can be clamped on the clamped object.

[0087] As another example, the support assembly can be gripped by a user.

[0088] For other examples, the support assembly can be clamped on a headrest or air outlet of a car.

[0089] For example, the shooting terminal 700 can be an electronic terminal such as a mobile phone or a tablet, and the shooting terminal 700 can also be a dedicated imaging terminal such as a camera or a video camera.

[0090] For example, the second arm 220 has one rotational degree of freedom relative to the first arm 210 , ie, the second arm 220 rotates about the first axis 201 .

[0091] In another example, the second arm 220 has three rotational degrees of freedom relative to the first arm 210 , and the three rotational degrees of freedom include a rotational degree of freedom of the second arm 220 rotating around the first axis 201 .

[0092] For example, the supporting member 300 is movably mounted on the second arm 220 , for example, the supporting member 300 is rotatably mounted on the second arm 220 .

[0093] In another example, the supporting member 300 is fixedly installed on the second arm 220 .

[0094] For example, the supporting member 300 supports the fixture in different ways, such as clamping, magnetism, adsorption, insertion, etc.

[0095] For example, the supporting member 300 is a clamp that can clamp the shooting terminal 700. For example, the supporting member 300 includes a carrying body 310 and two clamping parts 320. The two clamping parts 320 are respectively located at both ends of the carrying body 310. The carrying body 310 can be elastically extended and retracted to clamp shooting terminals 700 of different sizes. The two clamping parts 320 are both rotatably installed on the carrying body 310. When the supporting member 300 is needed, the clamping part 320 is opened relative to the carrying body 310. When the supporting member 300 is not needed, the clamping part 320 is stored in the carrying body 310.

[0096] For example, the supporting member 300 has a second magnetic portion, and the second magnetic portion can magnetically attract the shooting terminal 700.

[0097] For example, the supporting member 300 has a second suction cup, and the second suction cup can adsorb the shooting terminal 700.

[0098] For example, the supporting component 300 has a first quick-release interface, and the photographing terminal 700 has a first quick-release connector. The first quick-release connector can be inserted into the first quick-release interface.

[0099] For example, the supporting member 300 has a second quick-release connector, the photographing terminal 700 has a second quick-release interface, and the second quick-release connector can be inserted into the second quick-release interface.

[0100] Illustratively, the transmission cable 400 is a single-strand wire or a multi-strand wire.

[0101] For example, the transmission cable 400 is used to transmit the power of the battery 240 to the driving assembly 530 , and the transmission cable 400 is used to transmit the signal of the control mainboard 250 to the driving assembly 530 .

[0102] It can be understood that the transmission cable 400 is flexible, and when the second arm 220 rotates relative to the first arm 210 , the transmission cable 400 can be adaptively deformed (eg, bent).

[0103] It should be understood that the transmission cable 400 is installed on the first arm 210 , and the transmission cable 400 extends from the first arm 210 to the second arm 220 , that is, the transmission cable 400 is also installed on the second arm 220 .

[0104] For example, the transmission cable 400 is exposed relative to the first arm 210 , for example, the transmission cable 400 is attached to a surface of the first arm 210 .

[0105] For example, the transmission cable 400 is internally mounted relative to the first arm 210 , for example, the transmission cable 400 passes through the first arm 210 .

[0106] For example, the transmission cable 400 is partially exposed relative to the first arm 210 , for example, a portion of the transmission cable 400 is attached to the surface of the first arm 210 , and a portion thereof is passed through the first arm 210 .

[0107] For example, the transmission cable 400 is exposed relative to the second arm 220 , for example, the transmission cable 400 is attached to a surface of the second arm 220 .

[0108] For example, the transmission cable 400 is internally mounted relative to the second arm 220 . For example, the transmission cable 400 passes through the second arm 220 .

[0109] For example, the transmission cable 400 is partially exposed relative to the second arm 220 , for example, a portion of the transmission cable 400 is attached to the surface of the second arm 220 , and a portion of the transmission cable 400 is passed through the first arm 210 .

[0110] It can be understood that object A is mounted on object B for rotation around an axis. The maximum rotation angle of object A relative to object B around the axis refers to the maximum angle that object A can rotate around the axis relative to object B in a clockwise or counterclockwise manner. For example, the maximum rotation angle of object A relative to object B around the axis is less than or equal to α.

[0111] It can be understood that the first maximum rotation angle of the second arm 220 relative to the first arm 210 around the first axis 201 refers to the first maximum rotation angle of the second arm 220 relative to the first arm 210 around the first axis 201 clockwise or counterclockwise.

[0112] For example, the first maximum rotation angle of the second arm 220 relative to the first arm 210 around the first axis 201 is less than or equal to 270°. Specifically, the first maximum rotation angle is 270°, 240°, 210°, 180°, 150°, 120°, 90°, etc. The first maximum rotation angle is less than or equal to 270°, which avoids multiple rotations of the second arm 220 relative to the first arm 210, and avoids damage to the transmission cable 400 due to excessive torsion.

[0113] In some implementations of the present invention, referring to Figure 3 、 Figure 13 、 Figure 43 Etc., a first maximum rotation angle of the second arm 220 relative to the first arm 210 around the first axis 201 is greater than or equal to 175° and less than or equal to 270°.

[0114] The advantage of such a configuration is that the second arm 220 can be rotated at a right angle relative to the first arm 210, thereby facilitating right-angle rotation of the photographing terminal 700 or changing the position of the photographing terminal 700. Right-angle rotation refers to rotation of 180°.

[0115] For example, the shooting terminal 700 has a usage line, which is perpendicular to the display surface of the shooting terminal 700 or parallel to the axis of the shooting lens of the shooting terminal 700. When the usage line of the shooting terminal 700 is perpendicular to the first axis 201, the second arm 220 can rotate at a right angle relative to the first arm 210 to make the shooting terminal 700 rotate at a right angle. For example, the right-angle rotation of the shooting terminal 700 can make its display surface turn from downward to upward (or from upward to downward), turn from left to right (or from right to left), turn from facing the user to away from the user (or from away from the user to facing the user), etc.; the right-angle rotation of the shooting terminal 700 can make its shooting lens turn from downward to upward (or from upward to downward), turn from left to right (or from right to left), turn from facing the user to away from the user (or from away from the user to facing the user), etc.

[0116] For another example, when the use line of the shooting terminal 700 is parallel to the first axis 201, the second arm 220 can rotate at a right angle relative to the first wall to change the width of the shooting terminal 700, for example, the display surface of the shooting terminal 700 changes from a normal display to a reverse display, and for another example, the shooting lens of the shooting terminal 700 changes from a normal shooting to a reverse shooting.

[0117] For another example, when the shooting terminal 700 is located on one side of the first axis 201, the second arm 220 can rotate at a right angle relative to the first arm 210 to change the position of the shooting terminal 700, for example, the shooting terminal 700 rotates from the left side of the first axis 201 to the right side (or the right side to the left side), from the front side of the first axis 201 to the back side (from the back side to the front side), from the upper side of the first axis 201 to the lower side (from the lower side to the upper side), etc.

[0118] For example, the first maximum rotation angle is 175°, 180°, 270°, etc.

[0119] In some implementations of the present invention, referring to Figure 3 、 Figure 13 、 Figure 43 The first maximum rotation angle of the second arm 220 relative to the first arm 210 around the first axis 201 is 180°.

[0120] The advantage of such a configuration is that the second arm 220 can be quickly rotated at a right angle relative to the first arm 210 from the initial position, thereby enabling the photographing terminal 700 to be quickly adjusted.

[0121] In some implementations of the present invention, referring to Figure 1-Figure 42 or Figures 43-47 The first arm 210 is provided with a first wire passing channel 202, and the second arm 220 is provided with a second wire passing channel 203. The transmission cable 400 extends to the second wire passing channel 203 through the first wire passing channel 202. During the process of the second arm 220 rotating relative to the first arm 210 around the first axis 201, the first wire passing channel 202 and the second wire passing channel 203 are always connected.

[0122] It can be understood that during the rotation of the second arm 220 relative to the first arm 210 around the first axis 201, the first wire channel 202 and the second wire channel 203 are always connected, so as to facilitate the transmission cable 400 to extend from the first wire channel 202 to the second wire channel 203.

[0123] It should be understood that during the process of the second arm 220 rotating around the first axis 201 relative to the first arm 210, the transmission cable 400 may stick to the cavity wall of the first wire channel 202 and the second wire channel 203, and the first wire channel 202 or the second wire channel 203 may cause the transmission cable 400 to undergo adaptive deformation, and the first wire channel 202 or the second wire channel 203 will not destructively squeeze the transmission cable 400.

[0124] It can be understood that the transmission cable 400 extends in the first cable passage 202 and the second cable passage 203, so that the structure of the terminal bracket is more compact and occupies a smaller volume.

[0125] In some implementations of the present invention, referring to Figure 1-Figure 42 or Figures 43-47 The first arm body 210 includes a first arm body 211 and a first rotation limiting portion 212 provided on the first arm body 211, the first line-passing channel 202 extends to the first arm body 211, the second arm body 220 includes a second arm body 221 and a second rotation limiting portion provided on the second arm body 221, and the second line-passing channel 203 extends to the second arm body 221; the first rotation limiting portion 212 has a first limiting wall 212a and a second limiting wall 212b, and the second rotation limiting portion has a third limiting wall 222a and a fourth limiting wall 223a. In the initial state, the first limiting wall 212a is counteracted by the third limiting wall 222a. After the second arm body 220 rotates the first maximum angle relative to the first arm body 210, the second limiting wall 212b is counteracted by the fourth limiting wall 223a.

[0126] It can be understood that the first rotation limiting portion 212 and the second rotation limiting portion ensure that the rotation angle of the second arm 220 relative to the first arm 210 around the first axis 201 does not exceed the first maximum rotation angle, thereby preventing the transmission cable 400 from being damaged by excessive twisting.

[0127] For example, the first rotation limiting portion 212 is provided on the outer surface of the first arm body 211 , and the second rotation limiting portion is provided on the outer surface of the second arm body 221 .

[0128] In another example, the first rotation limiting portion 212 is built into the first arm body 211 , and the second rotation limiting portion is built into the second arm body 221 .

[0129] For example, the first rotation limiting portion 212 is a first protrusion 212 , which is located between the third limiting wall 222 a and the fourth limiting wall 223 a , and the first limiting wall 212 a and the second limiting wall 212 b are respectively located on opposite sides of the first protrusion 212 .

[0130] In other examples, the second rotation limiting portion is a protrusion, and the second rotation limiting portion is located between the first limiting wall 212a and the second limiting wall 212b.

[0131] It is understandable that during use of the terminal bracket, the second arm 220 may be in an intermediate state, that is, the first limiting wall 212a and the third limiting wall 222a do not abut against each other, and the second limiting wall 212b and the fourth limiting wall 223a do not abut against each other.

[0132] In some implementations of the present invention, referring to Figure 1-Figure 42The first rotation limiting part 212 is a first protrusion 212 provided on the first arm body 211, and the first limiting wall 212a and the second limiting wall 212b are located on the first protrusion 212; the second rotation limiting part is a second protrusion 222 and a third protrusion 223 provided on the second arm body 221, the third limiting wall 222a is located on the second protrusion 222, and the fourth limiting wall 223a is located on the third protrusion 223; the first protrusion 212 is protruded from the outer wall of the first arm body 211, and the second protrusion 222 and the third protrusion 223 are both protruded from the outer wall of the second arm body 221. The outer wall of the first arm body 211 surrounds the first axis 201, and the outer wall of the second arm body 221 surrounds the first axis 201.

[0133] It can be understood that the first protrusion 212 is arranged on the outer wall of the first arm body 211, and the second protrusion 222 and the third protrusion 223 are arranged on the outer wall of the second arm body 221, so that the first protrusion 212, the second protrusion 222, and the third protrusion 223 are farther away from the first axis 201. When the rotational torque applied to the second arm body 221 remains unchanged, the farther the first protrusion 212, the second protrusion 222, and the third protrusion 223 are from the first axis 201, the smaller the abutting pressure between the first protrusion 212 and the second protrusion 222, and the smaller the abutting pressure between the first protrusion 212 and the third protrusion 223, so that during the rotation of the second arm body 220 relative to the first arm body 210, the first protrusion 212, the second protrusion 222, and the third protrusion 223 are not easily broken.

[0134] For example, the first limiting wall 212 a and the second limiting wall 212 b are located on opposite sides of the first protrusion 212 .

[0135] It can be understood that in the initial state, the first protrusion 212 and the second protrusion 222 abut against each other. After the second arm 220 rotates relative to the first arm 210 by the first maximum angle, the first protrusion 212 and the third protrusion 223 abut against each other.

[0136] For example, the second protrusion 222 and the third protrusion 223 are respectively located on opposite sides of the second arm body 221 . In the initial state, after the second arm body 220 rotates 180° relative to the first arm body 210 , the first protrusion 212 and the third protrusion 223 abut against each other.

[0137] In some implementations of the present invention, referring to Figure 1-Figure 42The first protrusion 212 has a first protrusion plate 2121 and a first protrusion 2122 protruding from the first protrusion plate 2121. The first limiting wall 212a and the second limiting wall 212b are respectively located on opposite sides of the first protrusion 2122. The first protrusion 2122 extends along the surface of the first protrusion plate 2121. The first protrusion 2122 and the first protrusion plate 2121 both extend toward the outer space of the second arm body 221. The first protrusion 2122 is located between the first protrusion plate 2121 and the outer wall of the second arm body 221. The second protrusion 222 has a second protrusion 2122. 221, the third limiting wall 222a is located at the second ridge 2221, and when the first limiting wall 212a and the third limiting wall 222a are in abutment with each other, the second ridge 2221 is located between the first ridge plate 2121 and the outer wall of the second arm body 221; the third protrusion 223 has a third ridge 2231, and the fourth limiting wall 223a is located at the third ridge 2231, and when the second limiting wall 212b and the fourth limiting wall 223a are in abutment with each other, the third ridge 2231 is located between the first ridge plate 2121 and the outer wall of the second arm body 221.

[0138] It can be understood that the first protrusion 2122 is protruded from the first protruding plate 2121 and extends along the surface of the first protruding plate 2121, which improves the structural strength of the first protrusion 2122 and makes the first protrusion 2122 less likely to be damaged during the process of abutting against the third limiting wall 222a and the fourth limiting wall 223a.

[0139] It can be understood that the first protrusion 2122 is located between the first protrusion plate 2121 and the outer wall of the second arm body 221, and the third protrusion 2231 is located between the first protrusion plate 2121 and the outer wall of the second arm body 221, so that the first protrusion plate 2121 can block (or partially block) the first limiting wall 212a, the second limiting wall 212b, the third limiting wall 222a, and the fourth limiting wall 223a, so that the user's hand is not easily pinched when the first limiting wall 212a and the third limiting wall 222a are abutted, and the second limiting wall 212b and the fourth limiting wall 223a are abutted.

[0140] It can be understood that the first protrusion 2122 is located between the first protrusion plate 2121 and the outer side wall of the second arm body 221, and the third protrusion 2231 is located between the first protrusion plate 2121 and the outer side wall of the second arm body 221, making the structure of the connecting arm 200 more compact.

[0141] In some implementations of the present invention, referring to Figure 1-Figure 42The first protrusion 212 also has a first boss 2123 protruding from the outer wall of the first arm body 211, and the first protrusion 2122 and the first protrusion plate 2121 are both connected to the first boss 2123. During the rotation of the second arm body 220 relative to the first arm body 210, there is always a first gap 204 between the first protrusion 2122 and the outer wall of the second arm body 221; the second protrusion 222 also has a second boss 2222 protruding from the outer wall of the first arm body 211, the second protrusion 2221 protrudes from the second boss 2222, and the second protrusion 2221 extends along the surface of the second boss 2222. When the limiting wall 212a is in abutment with the third limiting wall 222a, the second boss 2222 is located in the first gap 204, and the first protrusion 2122 is close to the second boss 2222; the third protrusion 223 also has a third boss 2232 protruding from the outer wall of the first arm body 211, and the third protrusion 2231 is protruding from the third boss 2232, and the third protrusion 2231 extends along the surface of the third boss 2232. When the second limiting wall 212b is in abutment with the fourth limiting wall 223a, the third boss 2232 is located in the first gap 204, and the first protrusion 2122 is close to the third boss 2232.

[0142] It can be understood that there is always a first gap 204 between the first protrusion 2122 and the outer wall of the second arm body 221, which avoids interference between the first protrusion 2122 and the outer wall arm of the second arm body 221 during the rotation of the second arm body 220 relative to the first arm body 210.

[0143] It can be understood that the first protrusion 2122 and the first protrusion plate 2121 are both connected to the first boss 2123 , thereby improving the structural strength of the first protrusion 2122 .

[0144] It can be understood that the second protrusion 2221 is protruded from the second boss 2222 and extends along the surface of the second boss 2222, thereby improving the structural strength of the second protrusion 2221, and when the first limiting wall 212a and the third limiting wall 222a are in a state of abutting each other, the second boss 2222 is located in the first gap 204, making the structure of the connecting arm 200 more compact.

[0145] It can be understood that the third protrusion 2231 is protruded from the third boss 2232 and extends along the surface of the third boss 2232, thereby improving the structural strength of the third protrusion 2231, and when the second limiting wall 212b and the fourth limiting wall 223a are in abutment against each other, the third boss 2232 is located in the first gap 204, making the structure of the connecting arm 200 more compact.

[0146] In some implementations of the present invention, referring to Figure 1-Figure 42 ,or Figures 43-47The first arm body 210 includes a first arm body 211 and a first rotating portion 213 provided on the first arm body 211. The second arm body 220 includes a second arm body 221 and a second rotating portion 224 provided on the second arm body 221. The second rotating portion 224 rotates with the first rotating portion 213 to realize that the second arm body 220 can rotate around the first axis 201 relative to the first arm body 210; the first wire-passing channel 202 extends from the first arm body 211 to the first rotating portion 213, and the second wire-passing channel 203 extends from the second arm body 221 to the second rotating portion 224; the first rotating portion 213 It is a rotary groove, the second rotating part 224 is a rotary protrusion, the first wire-passing channel 202 has a first wire-passing opening 202a for the transmission cable 400 to extend out of the first arm body 210, and the first wire-passing opening 202a is located at the end of the first rotating part 213. The second wire-passing channel 203 has a second wire-passing opening 203a for the transmission cable 400 to extend out of the second arm body 220, and the second wire-passing opening 203a is located at the end of the second rotating part 224. During the rotation of the second arm body 220 relative to the first arm body 210, the first wire-passing opening 202a and the second wire-passing opening 203a are always connected.

[0147] It can be understood that the first rotating part 213 and the second rotating part 224 facilitate the second arm 220 to be rotatably installed on the first arm 210, and on the other hand, it is also convenient to set the first wire opening 202a and the second wire opening 203a so that the transmission cable 400 extends from the first arm 210 to the second arm 220.

[0148] It can be understood that the first wire-passing opening 202a is set at the end of the first rotating part 213 and the second wire-passing opening 203a is set at the end of the second rotating part 224, so that the transmission cable 400 is close to the first axis 201 when passing through the first rotating part 213 and the second rotating part 224, so that the deformation of the transmission cable 400 when following the rotation of the second arm body 220 or the first arm body 210 is smaller.

[0149] In another example, the first rotating portion 213 is a rotating protrusion, and the second rotating portion 224 is a rotating groove.

[0150] In some implementations of the present invention, referring to Figure 1-Figure 42 ,or Figures 43-47The second arm body 220 also includes a first connecting column 225a and a first connecting member 225b. The first connecting column 225a is protruded from the second arm body 221. The first arm body 211 is provided with a first connecting hole. The first connecting member 225b passes through the first connecting hole and cooperates with the first connecting column 225a. The first connecting member 225b is used to prevent the second rotating part 224 from separating from the first rotating part 213. The first axis 201 passes through the first connecting column 225a and the first connecting member 225b; the second rotating part 224 is annular, and the second rotating part 224 surrounds the first connecting column 225a. There is an installation cavity 205 between the second rotating part 224 and the first connecting column 225a. The second wire passing channel 203 passes through the installation cavity 205, and the transmission cable 400 passes through the installation cavity 205.

[0151] It can be understood that the first axis 201 passes through the first connecting column 225a and the first connecting member 225b. On the one hand, it is convenient to set the first connecting column 225a and the first connecting member 225b without obstructing the first rotating part 213 and the second rotating part 224, and on the other hand, it is convenient to make the structure of the first connecting column 225a and the first connecting member 225b compact.

[0152] It can be understood that the transmission cable 400 passes through the installation cavity 205, and the installation cavity 205 is located between the second rotating portion 224 and the first connecting column 225a, so that the transmission cable 400 is close to the first axis 201, so that during the rotation of the second arm 220 relative to the first arm 210 around the first axis 201, the deformation of the transmission cable 400 is small.

[0153] It can be understood that the second rotating portion 224 surrounds the first connecting column 225 a in a ring shape, and the transmission cable 400 passes through the installation cavity 205, so that the structure of the connecting arm 200 is compact.

[0154] It is understandable that during the rotation of the second arm 220 relative to the first arm 210 , the transmission cable 400 may stick to the wall of the installation cavity 205 , and the transmission cable 400 may undergo adaptive deformation.

[0155] It is understandable that during the rotation of the second arm 220 relative to the first arm 210 , the transmission cable 400 may stick to the edge of the first cable opening 202 a or the second cable opening 203 a , and the transmission cable 400 may undergo adaptive deformation.

[0156] It can be understood that a section of the second wire-passing channel 203 is located in the installation cavity 205 .

[0157] Exemplarily, the first connecting member 225b is a second fastener (such as a threaded fastener, a riveted fastener, etc.), and the first connecting column 225a is provided with a corresponding fastening hole (such as a threaded hole, a riveted hole, etc.), and the first connecting member 225b is fastened to the fastening hole of the first connecting column 225a.

[0158] In some implementations of the present invention, referring to Figure 1-Figure 42 ,or Figures 43-47 The second arm 220 also includes at least two spaced-apart connecting ribs 226, which are located in the mounting cavity 205, and the two ends of the connecting rib 226 are respectively connected to the second rotating portion 224 and the first connecting column 225a; the number of the connecting ribs 226 is at least two, and at least two of the connecting ribs 226 include two adjacent first connecting sub-ribs 226a, a section of the second wire-passing channel 203 is located between the two first connecting sub-ribs 226a, and a section of the transmission cable 400 is located between the two first connecting sub-ribs 226a.

[0159] It can be understood that the connecting rib 226 is connected to the second rotating portion 224 and the first connecting column 225 a , thereby enhancing the structural strength of the second rotating portion 224 and the first connecting column 225 a .

[0160] It can be understood that the transmission cable 400 passes through the space between the two first connecting sub-ribs 226 a, thereby preventing the connecting ribs 226 from affecting the passage of the transmission cable 400 .

[0161] understandably

[0162] For example, the number of the connecting ribs 226 is 2, 3, 4, etc.

[0163] In another example, the number of the connecting rib 226 is one.

[0164] It can be understood that two first connecting sub-ribs 226 a are adjacent to each other means that there is no other connecting rib 226 between the two first connecting sub-ribs 226 a.

[0165] In some implementations of the present invention, Figures 43-47The second arm body 220 also includes at least two spaced-apart connecting ribs 226, the connecting ribs 226 are located in the mounting cavity 205, and the two ends of the connecting ribs 226 are respectively connected to the second rotating portion 224 and the first connecting column 225a; the number of the connecting ribs 226 is at least 2, and the at least two connecting ribs 226 include two adjacent second connecting sub-ribs 226b, the first arm body 210 includes a first rotation limiting portion 212 provided on the first arm body 211, the second arm body 220 includes a second rotation limiting portion provided on the second arm body 221, the first rotation limiting portion 212 has a first limiting wall 212a and a second limiting wall 212b, and the second rotation limiting portion has a third limiting wall Wall 222a and the fourth limiting wall 223a, in the initial state, the first limiting wall 212a is against the third limiting wall 222a, and after the second arm body 220 rotates the first maximum angle relative to the first arm body 210, the second limiting wall 212b is against the fourth limiting wall 223a; the first limiting portion 212 is located between the two second connecting sub-ribs 226b, and the first limiting portion 212 is a protrusion protruding from the first arm body 211, and the first limiting portion 212 extends to the mounting cavity 205; the second limiting portion is the two second connecting sub-ribs 226b, and the third limiting wall 222a and the fourth limiting wall 223a are respectively located on the two second connecting sub-ribs 226b.

[0166] It can be understood that, on the one hand, the second connecting sub-rib 226b connects the second rotating part 224 and the first connecting column 225a to increase the structural strength of the second rotating part 224 and the first connecting column 225a; on the other hand, the second connecting sub-rib 226b also serves as a second rotation limiting part (i.e., the third limiting wall 222a and the fourth limiting wall 223a are respectively located on the two second connecting sub-ribs 226b), so that the structure of the connecting arm 200 is compact.

[0167] It can be understood that the first rotation limiting portion 212 is a protrusion protruding from the first arm body 211 , and the first rotation limiting portion 212 extends to the mounting cavity 205 , so that the structure of the connecting arm 200 is compact.

[0168] For example, the first connecting sub-rib 226 a and the second connecting sub-rib 226 b are different connecting ribs 226 , or the first connecting sub-rib 226 a and the second connecting sub-rib 226 b are the same connecting rib 226 .

[0169] It can be understood that two second connecting sub-ribs 226 b are adjacent to each other, which means that there is no other connecting rib 226 between the two second connecting sub-ribs 226 b.

[0170] In some implementations of the present invention, referring to Figure 1-Figure 42 ,or Figures 43-47The second arm body 220 can be retained on the first arm body 210. The connecting arm 200 also includes a damping ring 230. The damping ring 230 is sleeved on the second rotating part 224. The damping ring 230 is installed between the first rotating part 213 and the second rotating part 224 so that the second arm body 220 can be retained on the first arm body 210.

[0171] It can be understood that the second arm 220 can be retained on the first arm 210, so that the second arm 220 can be maintained at a certain position relative to the first arm 210, thereby keeping the shooting terminal 700 in a position for user use.

[0172] It can be understood that the damping ring 230 is interference fit with the second rotating part 224 , and the damping ring 230 is interference fit with the first rotating part 213 , so that friction damping is provided between the first rotating part 213 and the second rotating part 224 .

[0173] For example, the damping ring 230 may be made of an elastomeric polymer material, such as rubber, plastic, etc.

[0174] In other examples, the first rotating portion 213 and the second rotating portion 224 are directly or indirectly interference-fitted, so that friction damping is provided between the first rotating portion 213 and the second rotating portion 224 , so that the second arm 220 can be retained on the first arm 210 .

[0175] In other examples, the connecting arm 200 has a third fastener (for example, the third fastener is a threaded member or a rivet member), and the third fastener creates friction damping between the first rotating portion 213 and the second rotating portion 224 so that the second arm body 220 can be retained on the first arm body 210. For example, the third fastener passes through the second arm body 220 and is in frictional contact with the first arm body 210.

[0176] In some implementations of the present invention, referring to Figure 1-Figure 42 ,or Figures 43-47, the first arm body 210 includes a first arm body 211 and a first rotating portion 213 provided on the first arm body 211, the second arm body 220 includes a second arm body 221 and a second rotating portion 224 provided on the second arm body 221, the second rotating portion 224 rotates with the first rotating portion 213 to realize that the second arm body 220 can rotate around the first axis 201 relative to the first arm body 210, the first line-passing channel 202 extends to the first arm body 211 and the first rotating portion 213, the second line-passing channel 203 extends to the second arm body 221 and the second rotating portion 224; the first arm body 210 also includes a first rotation-limiting portion 212 provided on the first arm body 211, and the second arm body 220 is provided on the second rotation-limiting portion of the second arm body 221. In the initial state, the first rotation-limiting portion 212 and the second rotation-limiting portion are offset. After the second arm body 220 rotates the first maximum rotation angle relative to the first arm body 210, the first rotation-limiting portion 212 2 and the second rotation limiting portion, the first rotation limiting portion 212 has a first limiting wall 212a and a second limiting wall 212b, and the second rotation limiting portion has a third limiting wall 222a and a fourth limiting wall 223a. In the initial state, the first limiting wall 212a and the third limiting wall 222a are offset against each other. After the second arm 220 rotates the first maximum rotation angle relative to the first arm 210, the second limiting wall 212b and the fourth limiting wall 223a are offset against each other. The second rotating portion 2 24 is provided with an installation cavity 205, the second rotation limiting part is connected to the second rotating part 224, the second rotation limiting part is located in the installation cavity 205, the second wire passing channel 203 passes through the installation cavity 205, and the transmission cable 400 passes through the installation cavity 205; the first rotation limiting part 212 is a protrusion protruding from the first arm body 211, the first rotation limiting part 212 is located between the third limiting wall 222a and the fourth limiting wall 223a, and the first rotation limiting part 212 extends to the installation cavity 205.

[0177] It can be understood that the second rotation limiting portion is located in the installation cavity 205, the first rotation limiting portion 212 extends to the installation cavity 205, and the transmission cable 400 passes through the installation cavity 205, so that the structure of the connecting arm 200 is compact.

[0178] In some implementations of the present invention, referring to Figure 1-Figure 42The support assembly includes a support member 100 and a pan-tilt assembly 500, the pan-tilt assembly 500 is installed on the support member 100, the pan-tilt assembly 500 includes a fixed body 510, a rotating body 520 and a driving assembly 530, the fixed body 510 is installed on the support member 100, the rotating body 520 is rotatably installed on the fixed body 510, the rotating body 520 has a receiving cavity 501, the driving assembly 530 is received in the receiving cavity 501, and the driving assembly 530 is used to drive the rotating body 520 to rotate relative to the fixed body 510; the first arm 210 is installed on the rotating body The first arm 210 is rotatably mounted on the rotating body 520, wherein the transmission cable 400 extends from the first arm 210 to the accommodating cavity 501, and the transmission cable 400 is electrically connected to the drive assembly 530. The rotating body 520 defines a third cable passage 502, which is in communication with the accommodating cavity 501, and the transmission cable 400 extends to the accommodating cavity 501 through the third cable passage 502. The first arm 210 is rotatably mounted on the rotating body 520 about the second axis 902, and the second maximum rotation angle of the first arm 210 relative to the rotating body 520 about the second axis 902 is less than or equal to 270°.

[0179] During the rotation of the first arm 210 relative to the rotating body 520, the first wire passing channel 202 and the third wire passing channel 502 are always connected; the terminal bracket also includes a battery 240, and the second arm 220 is provided with a accommodating cavity 206, the battery 240 is accommodated in the accommodating cavity 206, and the transmission cable 400 is used to transmit the electrical energy of the battery 240 to the driving component 530.

[0180] It can be understood that the first arm 210 is installed on the rotating body 520. When the rotating body 520 rotates relative to the fixed body 510, the first arm 210 rotates with the rotating body 520, thereby adjusting the position of the shooting terminal 700.

[0181] It can be understood that the transmission cable 400 is used to transmit signals and / or electrical energy to the drive component 530, for example, the transmission cable 400 transmits signals to the drive component 530 to control the action of the drive component 530, for example, the transmission cable 400 transmits electrical energy to the drive component 530 to enable the drive component 530 to continue to move.

[0182] For example, the driving component 530 is a motor or the like.

[0183] For example, the driving component 530 is a motor, which includes a motor body 531 and an output shaft 532 . The motor body 531 is installed on the fixed body 510 , and the output shaft 532 directly drives the rotating body 520 . The transmission cable 400 is electrically connected to the motor body 531 .

[0184] For example, the driving assembly 530 is a motor, and the driving assembly 530 includes a motor body 531 and an output shaft 532 . The motor body 531 is mounted on the rotating body 520 , and the output shaft 532 is transmission-connected to the fixed body 510 .

[0185] For example, the third wire-passing channel 502 is in communication with the second wire-passing channel 203 , and the transmission cable 400 extends into the accommodating cavity 501 through the second wire-passing channel 203 and the third wire-passing channel 502 .

[0186] The advantage of this arrangement is that the second maximum rotation angle is less than or equal to 270°, which avoids multiple rotations of the first arm 210 relative to the rotating body 520, thereby preventing the transmission cable 400 from being damaged due to excessive torsion.

[0187] For example, the second maximum rotation angle is 270°, 240°, 210°, 180°, 150°, 120°, 90°, etc.

[0188] It can be understood that during the rotation of the first arm 210 relative to the rotating body 520, the first wire channel 202 and the third wire channel 502 are always connected, so that the transmission cable 400 extends from the first wire channel 202 to the third wire channel 502.

[0189] It should be understood that during the rotation of the first arm 210 around the first axis 201 relative to the pan-tilt assembly 500, the transmission cable 400 may stick to the cavity wall of the first wire channel 202 or the third wire channel 502. The first wire channel 202 or the third wire channel 502 may cause the transmission cable 400 to undergo adaptive deformation, and the first wire channel 202 or the third wire channel 502 will not destructively squeeze the transmission cable 400.

[0190] It can be understood that the transmission cable 400 extends in the first cable passage 202 and the third cable passage 502, so that the structure of the terminal bracket is more compact and occupies a smaller volume.

[0191] It can be understood that accommodating the battery 240 and the driving component 530 in the accommodating cavity 206 and the accommodating cavity 501 respectively, on the one hand, avoids damage to the driving component 530 caused by destructive damage to the battery 240 (such as bulging, leakage, explosion, etc.), and on the other hand, avoids the volume of the battery 240 being limited by the driving component 530, the rotating body 520, etc., so that the volume of the battery 240 can be larger, thereby making the capacity of the battery 240 larger.

[0192] In some implementations of the present invention, referring to Figure 1-Figure 42The rotating body 520 has a fifth limiting wall 503 and a sixth limiting wall 504. In the initial state, the first arm body 210 is against the fifth limiting wall 503. After the first arm body 210 rotates relative to the rotating body 520 at the second maximum rotation angle, the first arm body 210 is against the sixth limiting wall 504. The rotating body 520 has a connecting head 521a. The first arm body 210 includes a first arm body 211 and at least one extension bar 214. The at least one extension bar 214 is protruded from the first arm body 211. The at least one extension bar 214 is rotated The first arm 210 is mounted on the connecting head 521a. In the initial state, the extension bar 214 abuts against the fifth limiting wall 503. After the rotating body 520 rotates to the second maximum angle, the extension bar 214 abuts against the sixth limiting wall 504. The rotating body 520 has a supporting protrusion 521b connected to the connecting head 521a. The supporting protrusion 521b protrudes from the connecting head 521a. The fifth limiting wall 503 and the sixth limiting wall 504 are both located on the supporting protrusion 521b. The first arm 210 can be retained on the rotating body 520. The terminal bracket also includes a first fastener. 610, the first fastener 610 passes through the connector 521a and the extension bar 214 so that the extension bar 214 is rotatably mounted on the connector 521a around the second axis 902. The first fastener 610 is also used to provide friction damping between the extension bar 214 and the connector 521a. One of the at least one extension bar 214 is a first extension sub-bar 214a. The first wire channel 202 extends to the first extension sub-bar 214a. The first wire channel 202 has a third wire opening for the transmission cable 400 to extend out of the first arm 210. 202b, the third wire-passing opening 202b is arranged on the side of the first extension sub-strip 214a, and the third wire-passing channel 502 has a fourth wire-passing opening 502a for the transmission cable 400 to extend out of the rotating body 520. The fourth wire-passing opening 502a is arranged on the side of the connecting head 521a. During the rotation of the first arm 210 relative to the rotating body 520, the third wire-passing opening 202b and the fourth wire-passing opening 502a are always connected; the number of extension strips 214 is 2, and the connecting head 521a is located between the two extension strips 214.

[0193] It can be understood that the fifth limiting wall 503 and the sixth limiting wall 504 prevent the first arm 210 from rotating relative to the pan / tilt head assembly 500 by more than the second maximum rotation angle, thereby preventing the transmission cable 400 from being damaged by excessive twisting.

[0194] It can be understood that the connecting head 521 a and the extension bar 214 facilitate the rotational connection between the rotating body 520 and the first arm 210 .

[0195] It can be understood that the abutting protrusion 521 b protrudes from the connecting head 521 a to facilitate the arrangement of the fifth limiting wall 503 and the sixth limiting wall 504 .

[0196] It can be understood that the first fastener 610 is used to realize the rotational connection between the first arm 210 and the connecting head 521a, and to provide friction damping between the first arm 210 and the connecting head 521a, thereby making the structure of the terminal bracket compact. The first fastener 610 can be a threaded part or a riveted part.

[0197] It can be understood that the third wire opening 202b is provided on the side of the first extension sub-strip 214a, and the fourth wire opening 502a is located on the side of the connector 521a, so as to facilitate communication between the third wire opening 202b and the fourth wire opening 502a.

[0198] For example, the extension strip 214 is provided on the first friction groove 214b, and the connector 521a is provided with the second friction groove 521c. The first friction groove 214b and the second friction groove 521c are in friction contact. The first friction groove 214b is a positive groove or a negative groove, and the second friction groove 521c is a positive groove or a negative groove.

[0199] For example, the first arm body 210 includes a first arm main housing 210a and a first arm sub-housing 210b mounted on the first arm main housing 210a. The first arm sub-housing 210b is part of the first extension sub-bar 214a. The first arm main housing 210a defines a first arm opening 207 that mates with the first arm sub-housing 210b. The first arm sub-housing 210b seals the first arm opening 207, which communicates with the second cable passage 203. The transmission cable 400 can be arranged through the first arm opening 207 to facilitate installation. The transmission cable 400 can be inserted into the second cable passage 203 through the first arm opening 207 and extend to the second cable passage opening 203a. Alternatively, the transmission cable 400 can be inserted into the second cable passage 203 through the second cable passage opening 203a. The control board 250, tracking camera 260, battery 240, etc. can be installed into the accommodating cavity 206 through the first arm opening 207.

[0200] For example, the second arm body 220 includes a second arm main shell 220a and a second arm sub-shell 220b installed on the second arm main shell 220a. The second arm main shell 220a and the second arm sub-shell 220b are part of the second arm body 221. The second arm main shell 220a is provided with a second arm opening 208 adapted to the second arm main shell 220a. The second arm sub-shell 220b closes the second arm opening 208. The second arm opening 208 is connected to the first wire channel 202. The transmission cable 400 can be arranged through the second arm opening 208 to facilitate the installation of the transmission cable 400. The transmission cable 400 is loaded into the first wire channel 202 through the first wire opening 202a and extends to the third wire opening 202b, or the transmission cable 400 is loaded into the first wire channel 202 through the third wire opening 202b and extends to the first wire opening 202a.

[0201] In some implementations of the present invention, referring to Figure 1-Figure 42 ,or Figures 43-47 , the rotating body 520 has a connecting head 521a, the first arm 210 has at least one extension bar 214, and at least one extension bar 214 is rotatably mounted on the connecting head 521a; the first arm 210 can be retained on the rotating body 520, and the terminal bracket also includes a first fastener 610, the first fastener 610 passes through the connecting head 521a and the extension bar 214 so that the extension bar 214 is rotatably mounted on the connecting head 521a around the second axis 902, and the first fastener 610 is also used to provide friction damping between the extension bar 214 and the connecting head 521a; the first wire channel 202 extends to the first extension sub-bar 214a, and the first wire channel 202 has a third wire opening 202b for the transmission cable 400 to extend out of the first arm 210, and the third wire opening 202b is provided at the first On the side of the extended sub-strip 214a, the third wire-passing channel 502 has a fourth wire-passing opening 502a for the transmission cable 400 to extend out of the rotating body 520. The fourth wire-passing opening 502a is arranged on the side of the connecting head 521a. During the rotation of the first arm 210 relative to the rotating body 520, the third wire-passing opening 202b and the fourth wire-passing opening 502a are always connected; the first extended sub-strip 214a has a first mounting protrusion 214c, the connecting head 521a has a second mounting protrusion 521d, the first fastener 610 passes through the first mounting protrusion 214c and the second mounting protrusion 521d, the third wire-passing opening 202b is a partial annular opening surrounding the first mounting protrusion 214c, and the fourth wire-passing opening 502a is a partial annular opening surrounding the second mounting protrusion 521d.

[0202] It can be understood that the first fastener 610 passes through the first mounting protrusion 214c and the second mounting protrusion 521d, the third wire opening 202b is a partial annular opening surrounding the first mounting protrusion 214c, and the fourth wire opening 502a is a partial annular opening surrounding the second mounting protrusion 521d; the advantage of this arrangement is that during the rotation of the first arm 210 relative to the pan-tilt assembly 500, the transmission cable 400 is close to the second axis 902, so that the deformation of the transmission cable 400 during the rotation of the first arm 210 (or pan-tilt assembly 500) is smaller.

[0203] It can be understood that the third wire opening 202b is set as a partial annular opening surrounding the first mounting protrusion 214c, so that the third wire opening 202b can easily avoid the transmission cable 400 during the rotation of the first arm 210 relative to the pan-tilt assembly 500, making the transmission cable 400 less likely to be damaged.

[0204] It can be understood that the fourth wire opening 502a is set as a partial annular opening surrounding the second mounting protrusion 521d, so that the fourth wire opening 502a can easily avoid the transmission cable 400 during the rotation of the first arm 210 relative to the pan-tilt assembly 500, making the transmission cable 400 less likely to be damaged.

[0205] For example, the partial annular opening refers to a section of the annular opening, and the partial annular opening may be a section of a circular annular opening.

[0206] For example, the partial annular opening is a fan-shaped ring, a waist-shaped ring, etc.

[0207] It can be understood that setting the third wire opening 202b as a partial annular opening also facilitates the connection between the first mounting protrusion 214c and other parts of the first extension sub-strip 214a, and setting the fourth wire opening 502a as a partial annular opening also facilitates the connection between the second mounting protrusion 521d and other parts of the connector 521a.

[0208] In some implementations of the present invention, referring to Figure 1-Figure 42 The terminal bracket also includes a control motherboard 250 and a tracking camera 260. The control motherboard 250 is electrically connected to the tracking camera 260, the battery 240, and the transmission cable 400. The transmission cable 400 is also used to transmit the signal of the control motherboard 250 to the driving component 530, and the tracking camera 260 rotates with the rotating body 520; the tracking camera 260 is used to shoot the tracked object, and the control motherboard 250 is used to process the picture of the tracking camera 260 to control the driving component 530 to drive the rotating body 520 so that the tracked object is in the picture of the tracking camera 260; the shooting terminal 700 has a shooting lens 710. When the tracking camera 260 is in the state of following the tracked object, the shooting lens 710 shoots the tracked object; the tracking camera 260 and the control motherboard 250 are both installed on the second arm body 220, and the tracking camera 260 and the control motherboard 250 are both accommodated in the accommodating cavity 206 of the second arm body 220.

[0209] It can be understood that the control mainboard 250 and the driving component 530 make the tracked object appear in the picture of the tracking camera 260, so that the terminal bracket can track the object.

[0210] It can be understood that the transmission cable 400 transmits the signal of the control mainboard 250 to the driving assembly 530 so that the control mainboard 250 controls the driving assembly 530 .

[0211] It can be understood that during the tracking process, the tracking camera 260 and the shooting lens 710 are located on the same side, so that the shooting lens 710 can shoot the tracked object.

[0212] For example, the tracked object may be a person, an object, etc.

[0213] It can be understood that when the rotating body 520 rotates, the tracking camera 260 rotates along with the rotating body 520 .

[0214] For example, the tracking camera 260 is disposed on the rotating body 520 , the connecting arm 200 or the supporting member 300 ; specifically, the tracking camera 260 is disposed on the second arm body 220 of the connecting arm 200 .

[0215] It can be understood that, in the tracking state, the rotation speed of the rotating body 520 is related to the moving speed of the tracked subject.

[0216] In other examples, the driving component 530 is driven by other means, such as directly driving the driving component 530 by controlling the main board 250 .

[0217] It can be understood that the tracking camera 260 is installed on the second arm 220 so that the tracking camera 260 is closer to the shooting lens 710 of the shooting terminal 700, making it easier for the shooting lens 710 to shoot the tracked object.

[0218] For example, the control mainboard 250 and the tracking camera 260 are both accommodated in the accommodating cavity 206 of the second arm 220 .

The first locking member 560 is mounted on the fixed body 510. The second locking member 570 is slidably mounted on the rotating body 520. The second locking member 570 slides relative to the rotating body 520 so that the second locking member 570 and the first locking member 560 can be locked. A locking member 560 is locked or disengaged, and the first locking member 560 and the second locking member 570 are locked and matched to lock the rotating body 520 relative to the fixed body 510; the first locking member 560 has a plurality of first prongs 561, and the plurality of first prongs 561 are annularly arranged around the third axis 508, and the second locking member 570 has at least one second prong 571.

[0226] For example, the first inserting tooth 561 and the second inserting tooth 571 both extend along the sliding direction of the second locking member 570 , so that the second inserting tooth 571 is inserted into the first inserting tooth 561 during the sliding process of the second locking member 570 .

[0231] Specifically, the rotating body 520 includes an outer shell 521 and an inner shell assembly. The first arm 210 is rotatably mounted on the outer shell 521. The connector 521a is located on the outer shell 521. The outer shell 521 surrounds and forms a first cavity. The accommodating cavity 501 is a portion of the first cavity, and the inner shell assembly is accommodated within the first cavity. The inner shell assembly is fixedly mounted on the outer shell 521 and includes a first inner shell 522 and a second inner shell 523. The first inner shell 522 is located between the motor body 531 and the second inner shell 523. The first inner shell 522 is fixedly mounted on the outer shell 521, and the motor body 531 is fixedly mounted on the first inner shell 522.

[0232] Specifically, the outer shell 521 is provided with an installation opening 507 connecting the first cavity and the accommodating cavity 501. The installation opening 507 is connected to the third wire-passing channel 502. The transmission cable 400 is installed in the third wire-passing channel 502 through the installation opening 507 and extends to the fourth wire-passing opening 502a. The inner shell assembly is installed in the first cavity through the installation opening 507. The drive assembly 530, the bearing 540, the first gear 551, the second gear 552, the first locking member 560, etc. are installed in the accommodating cavity 501 through the installation opening 507.

[0233] Specifically, the housing 521 defines a toggle opening 506 , and the toggle portion 574 of the first locking member 560 is exposed to the rotating body 520 through the toggle opening 506 .

[0234] Specifically, a plurality of fifth fasteners 525 pass through the first inner shell 522 and are fastened to the motor body 531 . The fifth fasteners 525 may be screws or rivets.

[0235] Specifically, the first inner shell 522 divides the accommodating chamber 501 into a first accommodating sub-chamber 501a and a second accommodating sub-chamber 501b, the motor body 531 is located in the first accommodating sub-chamber 501a, the third wire-passing channel 502 is connected to the first accommodating sub-chamber 501a, the transmission cable 400 extends to the first accommodating sub-chamber 501a, and the transmission cable 400 is electrically connected to the motor body 531; the output shaft 532 extends from the first accommodating sub-chamber 501a to the second accommodating sub-chamber 501b, and the first gear 551 and the second gear 552 are both located in the second accommodating sub-chamber 501b.

[0236] Specifically, the bearing 540 is located in the second accommodating sub-cavity 501b, and the outer ring body 541 of the bearing 540 is used to support the second inner shell 523. A number of fourth fasteners 524 pass through the second inner shell 523 and are fastened to the first inner shell 522. The outer ring body 541 of the bearing 540 is fastened between the head of the fourth fastener 524 and the second inner shell 523, so that the outer ring body 541 of the bearing 540 is fixed to the second inner shell 523. The fourth fastener 524 also fixes the second inner shell 523 to the first inner shell 522. The fourth fastener 524 can be a threaded part or a riveted part.

[0237] Specifically, a portion of the second locking member 570 is slidably installed between the outer shell 521 and the inner shell assembly, the second inserting tooth 571 of the second locking member 570 is located in the second accommodating sub-cavity 501b, and the first inserting tooth 561 is located in the second accommodating sub-cavity 501b.

[0238] Specifically, the fixing body 510 is installed on the support rod 120. More specifically, the fixing body 510 has a plug-in column 511. The support rod 120 has a plug-in hole 104 adapted to the plug-in column 511. The plug-in column 511 and the plug-in hole 104 are interference fit.

[0239] In some implementations of the present invention, referring to Figure 1-Figure 42, the first arm body 210 is rotatably installed on the support assembly around the second axis 902, and the first arm body 210 can be rotated around the second axis 902 to a first position relative to the support assembly; the support assembly includes a support member 100, and the support member 100 includes a support seat 110 and a support rod 120, the support seat 110 can be supported on a support surface 901, and the support rod 120 is installed on the support seat 110, and the support rod 120 has a central axis 101; when the support seat 110 is supported on the support surface 901 and the first arm body 210 is in the first position relative to the support assembly, the second arm body 220 rotates relative to the first arm body 210 around the first axis 201, which can make the supporting member 300 and the shooting terminal 700 closer to the central axis 101 to improve the stability of the terminal bracket and the shooting terminal 700 on the support surface 901.

[0240] It can be understood that when the support rod 120 is less stable (for example, when the support rod 120 is prone to shaking), the second arm 220 rotates around the first axis 201 relative to the first arm 210 to make the supporting member 300 and the shooting terminal 700 closer to the central axis 101, thereby making the terminal bracket more stable.

[0241] It can be understood that when the support rod 120 has good stability (for example, the support rod 120 is not easy to shake), the second arm 220 rotates around the first axis 201 relative to the first arm 210 to move the supporting member 300 and the shooting terminal 700 away from the central axis 101, thereby expanding the range of use of the shooting terminal 700.

[0242] For example, the support base 110 includes at least three legs 112 , and the at least three legs 112 can be supported on the support surface 901 , and the at least three legs 112 are used to support the support rod 120 .

[0243] One implementation of at least three legs 112, the support seat 110 includes a support column 111 and at least three legs 112, the support rod 120 is installed on the support column 111, the legs 112 are rotatably installed on the support column 111, the at least three legs 112 can be opened relative to the support column 111, and the at least three legs 112 are maintained in an open state relative to the support column 111, so that the at least three legs 112 can be supported on the support surface 901; the legs 112 have a rotating shaft rotatably installed on the support column 111, the legs 112 have a supporting end and a supporting end, and the rotating shaft is located between the supporting end and the supporting end, the support seat 110 also includes a supporting member 113 movably installed on the support column 111, when the at least three legs 112 are open relative to the support column 111, the supporting member 113 is moved so that the supporting end of the leg 112 is abutted against the supporting member 113, so that the supporting end of the leg 112 can be supported on the support surface 901. Specifically, the supporting member 113 is rotatably installed on the support column 111, and the supporting member 113 has an avoidance groove 103 corresponding to at least three supporting legs 112, and the supporting member 113 has a supporting portion 113a corresponding to at least three supporting legs 112. When the supporting member 113 is located at the fifth position of the support column 111, the supporting leg 112 rotates relative to the support column 111, and the avoidance groove 103 is used to avoid the supporting leg 112; when the supporting leg 112 is opened relative to the support column 111 and the supporting member 113 is located at the sixth position of the support column 111, the supporting leg 112 can be abutted against the supporting portion 113a of the supporting member 113. The legs 112 rotate relative to the support column 111 so that at least three legs 112 can be stored in the support column 111. Specifically, the support column 111 is provided with at least three storage slots 102, and the at least three legs 112 correspond to the at least three storage slots 102 respectively, and the at least three legs 112 can be stored in the at least three storage slots 102; when the at least three legs 112 are all stored in the support column 111, the support column 111 and the at least three legs 112 can be held by the user.

[0244] Another implementation of at least three legs 112 is that the support seat 110 includes a sliding portion, at least three connecting rods and at least three legs 112. The sliding portion is slidably installed on the support rod 120, and the sliding portion can slide along the sliding direction of the support rod 120. The at least three connecting rods correspond to the at least three legs 112 respectively, one end of the connecting rod is rotatably connected to the support rod 120, and the other end is rotatably connected to the corresponding leg 112. The at least three legs 112 are all rotatably connected to the sliding portion, and the sliding portion slides relative to the support rod 120 to open or retract the at least three legs 112. When the at least three legs 112 are open, the at least three legs 112 can be supported on a support surface 901; when the at least three legs 112 are retracted, the at least three legs 112 can be held by the user.

[0245] For example, the support rod 120 is a telescopic rod or a fixed-length rod; specifically, the support rod 120 is a telescopic rod, and the telescopic support rod 120 can make the pan-tilt assembly 500, the connecting arm 200, the supporting member 300 and the shooting terminal 700 as a whole move away from or closer to the support base 110; when the support base 110 is supported on the support surface 901, the telescopic support rod 120 can adjust the distance between the shooting terminal 700 and the support surface 901; when the support base 110 is held by a user, the telescopic support rod 120 can adjust the distance between the shooting terminal 700 and the user.

[0246] For example, when the support base 110 is supported on the support surface 901, the central axis 101 of the support rod 120 is coaxial with the vertical line of the support assembly, or the angle between the central axis 101 of the support rod 120 and the vertical line of the support assembly is less than or equal to 5° and the distance between the central axis 101 and the vertical line of the support assembly is less than or equal to 1 cm.

[0247] It can be understood that the stability of an object on the support surface 901 is called stability, and the stability of an object is related to the height of its center of gravity or the rolling radius. Specifically, the area enclosed by the object's contact point on support surface 901 is called the support surface. The support surface is a portion of support surface 901. If the intersection of the object's vertical line of gravity and support surface 901 lies within the support surface, the object will not tip over. The mass distribution of an object is not necessarily uniform, and the area enclosed by the object's contact points with the support surface is not necessarily circular. The bottom edge point (line) around which the object might tip over is called the tipping point (line). The intersection of the vertical line of gravity passing through the object's center of gravity and the horizontal support surface is called the centroid (the intersection of the projection of the inclined support surface onto the horizontal plane passing through the tipping point and the vertical line of gravity is the centroid). The distance from the centroid to the tipping point (line) is called the tipping radius. For general objects, given a constant center of gravity height and a constant support surface size, the difficulty of tipping in different directions varies. Stability is directional. Therefore, stability should be defined as the degree of stability of an object on the support surface in a particular direction, which is called its stability in that direction. The stability of an object in a particular direction is related to the height of the object's center of gravity and the tipping radius of the object in that direction.

[0248] It can be understood that the stability of an object in a certain direction is inversely proportional to the height of the object's center of gravity and directly proportional to the object's rolling radius.

[0249] For example, when the support base 110 is supported on the support surface 901 and the first arm 210 is in the first position relative to the support assembly, the second arm 220 rotates around the first axis 201 relative to the first arm 210 to make the supporting member 300 and the shooting terminal 700 closer to the central axis 101, so that the vertical line of the terminal bracket and the shooting terminal 700 is more centered, and the flipping radius of the terminal bracket and the shooting terminal 700 is larger, so that the terminal bracket is not easy to tip over.

[0250] In some implementations of the present invention, referring to Figure 1-Figure 42 , when the support base 110 can be supported on a supporting surface 901, the angle between the central axis 101 and the plumb line is less than or equal to 5°; the angle between the second axis 902 and the central axis 101 is greater than or equal to 85° and less than or equal to 90°; the angle between the first axis 201 and the second axis 902 is greater than or equal to 85° and less than or equal to 90°; when the first arm 210 is in the first position relative to the support assembly, the angle between the first axis 201 and the central axis 101 is less than or equal to 5°; the supporting member 300 is rotatably mounted on the second arm 220, and the rotation of the supporting member 300 relative to the second arm 220 can make the supporting member 300 and the shooting terminal 700 located on one side of the first axis 201; the support assembly also includes a pan-tilt assembly 500, which is mounted on the support rod 120, and the first arm 210 is rotatably mounted on the pan-tilt assembly 500 around the second axis 902.

[0251] It can be understood that when the first arm 210 is in the first position relative to the supporting assembly and the supporting member 300 rotates relative to the second arm 220 so that the supporting member 300 and the shooting terminal 700 are located on one side of the first axis 201, the second arm 220 rotates around the first axis 201 relative to the first arm 210 so that the supporting member 300 and the shooting terminal 700 are close to or away from the central axis 101.

[0252] It can be understood that the central axis 101 of the support rod 120 is along or substantially along the plumb line, so that the support rod 120 is along or substantially along the plumb line, making the support assembly relatively stable.

[0253] It can be understood that the angle between the second axis 902 and the central axis 101 is greater than or equal to 85° and less than or equal to 90°, so that the second axis 902 is perpendicular or nearly perpendicular to the central axis 101, and the angle between the first axis 201 and the second axis 902 is greater than or equal to 85° and less than or equal to 90°, so that the first axis 201 is perpendicular or nearly perpendicular to the second direction; the advantage of the above setting is that it is convenient for the shooting terminal 700 to adjust the usage direction.

[0254] It can be understood that when the first arm 210 is in the first position relative to the supporting assembly and the supporting member 300 and the shooting terminal 700 are located on one side of the first axis 201, the angle between the first axis 201 and the central axis 101 is less than or equal to 5°. The second arm 220 rotates around the first axis 201 relative to the first arm 210 to make the supporting member 300 and the shooting terminal 700 closer to the central axis 101 to improve the stability of the terminal bracket. For example, the supporting member 300 and the shooting terminal 700 are closer to the central axis 101, so that the flip radius of the terminal bracket and the shooting terminal 700 on the support surface 901 is larger.

[0255] It can be understood that the angle between the two straight lines ranges from 0° to 90°.

[0256] For example, the angle between the central axis 101 and the plumb line is 0°, 1°, 2°, 3°, 4°, 5°, etc.

[0257] For example, the included angle between the second axis 902 and the central axis 101 is 85°, 86°, 87°, 88°, 89°, 90°, etc.

[0258] For example, the included angle between the first axis 201 and the second axis 902 is 85°, 86°, 87°, 88°, 89°, 90°, etc.

[0259] For example, when the first arm 210 is in the first position relative to the support assembly, the first axis 201 and the central axis 101 are aligned.

[0260] In another example, the supporting member 300 is fixedly installed on the second arm 220 , and the supporting member 300 and the photographing terminal 700 are located on one side of the first axis 201 .

[0261] In some implementations of the present invention, referring to Figure 1-Figure 42 The first arm 210 is mounted on the support assembly and rotates around the second axis 902 ; the support assembly has a first side wall 903 ; the first arm 210 rotates around the second axis 902 relative to the support assembly so that the connecting arm 200 is folded on the first side wall 903 .

[0262] It can be understood that when the terminal bracket is not in use, the second arm 220 can be folded onto the first side wall 903, so that the terminal bracket can occupy a small volume for easy storage.

[0263] For example, the first side wall 903 is located on the first side wall 903 of the pan / tilt assembly 500 .

[0264] In other examples, the first side wall 903 is located between the gimbal assembly 500 and the support base 110 . For example, the support base 110 includes a support column 111 and at least three legs 112 , and the first side wall 903 is located between the gimbal assembly 500 and the support column 111 .

[0265] In other examples, the first side wall 903 is located on the support base 110 . For example, the support base 110 includes a support column 111 and at least three legs 112 , and the first side wall 903 is located on the support column 111 .

[0266] In other examples, the support rod 120 has a first side wall 903 . For example, the support rod 120 is a telescopic rod. When the support rod 120 is in a telescopic state, the support rod 120 has the first side wall 903 .

[0267] It can be understood that the connecting arm 200 folded on the first side wall 903 may mean that the entire connecting arm 200 is in contact with or close to the first side wall 903 , or it may mean that a portion of the connecting arm 200 is in contact with or close to the first side wall 903 .

[0268] In some implementations of the present invention, referring to Figure 1-Figure 42 , when the connecting arm 200 is folded on the first side wall 903, the second arm body 220 is close to or attached to the first side wall 903, and the second arm body 220 is located between the first side wall 903 and the supporting member 300; the second arm body 220 rotates around the first axis 201 to a third position relative to the first arm body 210 so that when the connecting arm 200 is folded on the first side wall 903, the second arm body 220 is close to or attached to the first side wall 903; the first arm body 210 includes a first arm body 211 and at least one extension bar 214, at least one extension bar 214 is protruded from the first arm body 211; the at least one extension bar 214 is rotatably mounted on the support assembly, the second arm body 220 has a second arm body 221, the first arm body 211 and the second arm body 221 are both along Extending in a direction parallel to the first axis 201, the first arm body 211 and the second arm body 221 have the same cross-section; when the second arm body 220 is in the third position relative to the first arm body 210, the first arm body 211 and the second arm body 221 are aligned so that when the connecting arm 200 is folded on the first side wall 903, the first arm body 211 and the second arm body 221 are close to or attached to the first side wall 903; when the connecting arm 200 is folded on the first side wall 903, the second axis 902 and the second arm body 221 are located on both sides of the first side wall 903, and the extension strip 214 is curved so that when the connecting arm 200 is folded on the first side wall 903, the first arm body 211 and the second arm body 221 are close to or attached to the first side wall 903.

[0269] It can be understood that when the connecting arm 200 is folded against the first side wall 903, the second arm body 220 is close to or attached to the first side wall 903, and the second arm body 220 is located between the first side wall 903 and the supporting member 300, thereby reducing the size of the terminal bracket when stored. Specifically, the supporting member 300 is mounted on the second arm body 221 of the second arm body 220. When the connecting arm 200 is folded against the first side wall 903, the second arm body 221 is located between the first side wall 903 and the supporting member 300.

[0270] For example, when the second arm 220 is in the third position relative to the first arm 210, the shape of the connecting arm 200 is adapted to the first side wall 903, so that the second arm 220 is close to or attached to the first side wall 903. For example, the first side wall 903 extends straight, and when the second arm 220 is in the third position relative to the first arm 210, the second arm 220 and the first arm 210 are also aligned, so that the connecting arm 200 is adapted to the first side wall 903.

[0271] It can be understood that when the second arm body 220 is in the third position relative to the first arm body 210 , the first arm body 211 is aligned with the second arm body 221 , which can facilitate the first arm body 211 and the second arm body 221 to be folded on the first side wall 903 .

[0272] It can be understood that the first arm body 211 and the second arm body 221 have the same cross-sectional shape and extend in the same direction, so that the second arm body 220 can rotate relative to the first arm body 210 around the first axis 201 to align the first arm body 211 with the second arm body 221.

[0273] For example, the cross section of the first arm body 211 is polygonal, rectangular with rounded corners, drum-shaped, etc.

[0274] It can be understood that the first arm body 211 is aligned with the second arm body 221 so that when the connecting arm 200 is folded on the first side wall 903, the first arm body 211 and the second arm body 221 are close to or attached to the first side wall 903, so that the terminal bracket is more compact in structure and occupies a smaller volume in the stored state.

[0275] It can be understood that when the connecting arm 200 is folded on the first side wall 903 , the extending arm extends from one side of the first side wall 903 to the other side.

[0276] The present invention also provides a rotating connection structure. Figure 1-Figure 47 , used for a terminal bracket, the terminal bracket is used to support the shooting terminal 700, and is characterized in that the rotating connection structure includes a first arm body 210 and a second arm body 220, and the second arm body 220 is rotatably installed on the first arm body 210 around the first axis 201; the rotating connection structure also includes a transmission cable 400 for transmitting signals and / or electrical energy, the transmission cable 400 is installed on the first arm body 210, and the transmission cable 400 extends from the first arm body 210 to the second arm body 220, and the first maximum rotation angle of the second arm body 220 relative to the first arm body 210 around the first axis 201 is less than or equal to 270°.

[0277] In this rotating connection structure, the first maximum rotation angle of the second arm 220 relative to the first arm 210 around the first axis 201 is less than or equal to 270°, which avoids multiple rotations of the second arm 220 relative to the first arm 210, thereby avoiding excessive twisting of the transmission cable 400 and avoiding damage to the transmission cable 400 caused by excessive twisting of the transmission cable 400.

[0278] The present invention also provides a rotating connection structure. Figure 1-Figure 47 The rotating connection structure includes a pan-tilt assembly 500, a first arm 210 and a transmission cable 400. The pan-tilt assembly 500 has a accommodating cavity 501, the first arm 210 is installed on the rotating body 520, the transmission cable 400 extends from the first arm 210 to the accommodating cavity 501, and the transmission cable 400 is electrically connected to the driving assembly 530; the pan-tilt assembly 500 is provided with a third wire-passing channel 502, the third wire-passing channel 502 is connected to the accommodating cavity 501, and the transmission cable 400 extends to the accommodating cavity 501 through the third wire-passing channel 502; the first arm 210 is rotatably installed on the pan-tilt assembly 500 around the second axis 902, and the second maximum rotation angle of the first arm 210 relative to the rotating body 520 around the second axis 902 is less than or equal to 270°.

[0279] In this rotating connection structure, the second maximum rotation angle of the first arm 210 relative to the pan-tilt assembly 500 around the second axis 902 is less than or equal to 270°, thereby avoiding multiple rotations of the first arm 210 relative to the pan-tilt assembly 500, thereby avoiding excessive twisting of the transmission cable 400, and further avoiding damage to the transmission cable 400 caused by excessive twisting of the transmission cable 400.

[0280] The above is only used to illustrate the technical solution of the present invention and is not intended to limit it. Other modifications or equivalent substitutions made to the technical solution of the present invention by ordinary technicians in this field should be included in the scope of the claims of the present invention as long as they do not depart from the spirit and scope of the technical solution of the present invention.
