[0084] The present utility model will be further described in detail below with reference to the accompanying drawings.

[0085] This specific embodiment is only an explanation of the present utility model, and it is not a limitation of the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without creative contributions as needed, but as long as it is within the scope of the claims of the present utility model, it is protected by the Patent Law.

[0086] Refer to Figures 1 - 47 , a terminal bracket, the terminal bracket includes a support assembly, a connecting arm 200 and a supporting member 300. The support assembly is used to support the shooting terminal 700; the connecting arm 200 includes a first arm body 210 and a second arm body 220. The first arm body 210 is installed on the support assembly, and the second arm body 220 is rotatably installed on the first arm body 210 around the first axis 201; the supporting member 300 is installed on the second arm body 220, and the shooting terminal 700 is supported by the supporting member 300; the terminal bracket further includes a transmission cable 400 for transmitting signals and / or electric 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. 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°.

[0087] It can be understood that 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°, which avoids the multi-turn rotation of the second arm body 220 relative to the first arm body 210, thereby avoiding the excessive torsion of the transmission cable 400 and avoiding the damage of the transmission cable 400 caused by the excessive torsion of the transmission cable 400.

[0088] Exemplarily, the support assembly can be supported on a support surface 901. 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 another example, the support base 110 includes a support plate that can be supported on the support surface 901.

[0089] Exemplarily, the support assembly can be attached to an attachment surface. For example, the support assembly has a first magnetic attraction part, and the first magnetic attraction part can be magnetically attracted to the attachment surface. For another example, the support assembly has a first suction cup, and the first suction cup can be adsorbed on the attachment surface.

[0090] Exemplarily, the support assembly can be clamped on an object to be clamped. For example, the support assembly has a clip, and the clip can be clamped on the object to be clamped.

[0091] In other examples, the support component can be held by the user.

[0092] In other examples, the support component can be clamped to the headrest or air outlet of a car, etc.

[0093] 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.

[0094] For example, the second arm body 220 has one degree of rotational freedom relative to the first arm body 210, that is, the rotational freedom of the second arm body 220 rotating around the first axis 201.

[0095] In other examples, the second arm body 220 has three degrees of rotational freedom relative to the first arm body 210, and the three degrees of rotational freedom include the rotational freedom of the second arm body 220 rotating around the first axis 201.

[0096] For example, the supporting member 300 is movably installed on the second arm body 220. For example, the supporting member 300 is rotatably installed on the second arm body 220.

[0097] In other examples, the supporting member 300 is fixedly installed on the second arm body 220.

[0098] For example, the supporting member 300 supports the fixture in different ways, such as clamping, magnetic attraction, adsorption, insertion, etc.

[0099] For example, the supporting member 300 is a fixture that can clamp the shooting terminal 700. For example, the supporting member 300 includes a bearing body 310 and two clamping parts 320. The two clamping parts 320 are respectively located at both ends of the bearing body 310. The bearing body 310 can elastically expand and contract to clamp shooting terminals 700 of different sizes. The two clamping parts 320 are both rotatably installed on the bearing body 310. When the supporting member 300 is needed, the clamping part 320 is opened relative to the bearing body 310. When the supporting member 300 is not needed, the clamping part 320 is received in the bearing body 310.

[0100] For example, the supporting member 300 has a second magnetic attraction part, and the second magnetic attraction part can magnetically attract the shooting terminal 700.

[0101] For example, the supporting member 300 has a second suction cup, and the second suction cup can adsorb the shooting terminal 700.

[0102] For example, the supporting member 300 has a first quick-release interface, and the shooting terminal 700 has a first quick-release connector, and the first quick-release connector can be inserted into the first quick-release interface.

[0103] Exemplarily, the carrier 300 has a second quick-release joint, and the photographing terminal 700 has a second quick-release interface. The second quick-release joint can be inserted into the second quick-release interface.

[0104] Exemplarily, the transmission cable 400 is a single-strand cable or a multi-strand cable.

[0105] Exemplarily, the transmission cable 400 is used to transmit the electric energy of the battery 240 to the driving assembly 530, and the transmission cable 400 is used to transmit the signal of the control main board 250 to the driving assembly 530.

[0106] It can be understood that the transmission cable 400 is flexible. During the rotation of the second arm body 220 relative to the first arm body 210, the transmission cable 400 can undergo adaptive deformation (such as bending).

[0107] It should be understood that 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, that is, the transmission cable 400 is also installed on the second arm body 220.

[0108] Exemplarily, the transmission cable 400 is exposed relative to the first arm body 210. For example, the transmission cable 400 is attached to the surface of the first arm body 210.

[0109] Exemplarily, the transmission cable 400 is hidden relative to the first arm body 210. For example, the transmission cable 400 is threaded through the first arm body 210.

[0110] Exemplarily, the transmission cable 400 is partially exposed relative to the first arm body 210. For example, a part of the transmission cable 400 is attached to the surface of the first arm body 210 and a part is threaded through the first arm body 210.

[0111] Exemplarily, the transmission cable 400 is exposed relative to the second arm body 220. For example, the transmission cable 400 is attached to the surface of the second arm body 220.

[0112] Exemplarily, the transmission cable 400 is hidden relative to the second arm body 220. For example, the transmission cable 400 is threaded through the second arm body 220.

[0113] Exemplarily, the transmission cable 400 is partially exposed relative to the second arm body 220. For example, a part of the transmission cable 400 is attached to the surface of the second arm body 220 and a part is threaded through the first arm body 210.

[0114] It can be understood that object A is rotatably mounted on object B about an axis. The maximum rotation angle of object A relative to object B about this axis refers to the maximum angle that object A can rotate relative to B clockwise or counterclockwise about this axis. For example, the maximum rotation angle of object A relative to object B about this axis is less than or equal to α.

[0115] Understandably, the first maximum rotation angle of the second arm body 220 relative to the first arm body 210 about the first axis 201 refers to the first maximum rotation angle of the second arm body 220 relative to the first arm body 210 clockwise or counterclockwise about the first axis 201.

[0116] Exemplarily, the first maximum rotation angle of the second arm body 220 relative to the first arm body 210 about 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 being less than or equal to 270° avoids multiple turns of the second arm body 220 relative to the first arm body 210, and avoids damage to the transmission cable 400 due to excessive torsion.

[0117] In some implementation manners of the embodiments of the present utility model, referring to Figure 3 、 Figure 13 、 Figure 43 etc., the first maximum rotation angle of the second arm body 220 relative to the first arm body 210 about the first axis 201 is greater than or equal to 175° and less than or equal to 270°.

[0118] The advantage of such a setting is that it facilitates the flat-angle rotation of the second arm body 220 relative to the first arm body 210, facilitates the flat-angle rotation of the shooting terminal 700, or changes the position of the shooting terminal 700. Flat-angle rotation means rotating 180°.

[0119] For example, the shooting terminal 700 has a usage line that is perpendicular to the display surface of the shooting terminal 700 or parallel to the shooting lens axis of the shooting terminal 700. In a state where the usage line of the shooting terminal 700 is perpendicular to the first axis 201, the flat-angle rotation of the second arm body 220 relative to the first arm body 210 can cause the shooting terminal 700 to rotate flatly. For example, the flat-angle rotation of the shooting terminal 700 can cause its display surface to turn from facing down to facing up (or from facing up to facing down), from facing left to facing right (or from facing right to facing left), from facing the user to facing away from the user (or from facing away from the user to facing the user), etc.; the flat-angle rotation of the shooting terminal 700 causes its shooting lens to turn from facing down to facing up (or from facing up to facing down), from facing left to facing right (or from facing right to facing left), from facing the user to facing away from the user (or from facing away from the user to facing the user), etc.

[0120] Another example is that in a state where the usage line of the shooting terminal 700 is parallel to the first axis 201, the flat-angle rotation of the second arm body 220 relative to the first arm body can cause the radial direction of the shooting terminal 700 to change. For example, the display surface of the shooting terminal 700 changes from a positive radial display to an inverted radial display. Another example is that the shooting lens of the shooting terminal 700 changes from a positive radial shooting to an inverted radial shooting.

[0121] For another example, in a state where the photographing terminal 700 is located on one side of the first axis 201, a flat-angle rotation of the second arm body 220 relative to the first arm body 210 can change the position of the photographing terminal 700. For example, the photographing terminal 700 can be changed from the left side of the first axis 201 to the right side (or from the right side to the left side), from the front side of the first axis 201 to the rear side (from the rear 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.

[0122] Exemplarily, the first maximum rotation angle is 175°, 180°, 270°, etc.

[0123] In some implementation manners of the embodiments of the present invention, referring to Figure 3 、 Figure 13 、 Figure 43 etc., the first maximum rotation angle of the second arm body 220 relative to the first arm body 210 around the first axis 201 is 180°.

[0124] The advantage of such a setting is that the second arm body 220 can quickly perform a flat-angle rotation relative to the first arm body 210 from the initial position, so that the photographing terminal 700 can be quickly adjusted.

[0125] In some implementation manners of the embodiments of the present invention, referring to Figures 1 - 42 or Figures 43 - 47 , the first arm body 210 is provided with a first wire passing channel 202, and the second arm body 220 is provided with a second wire passing channel 203. The transmission cable 400 extends through the first wire passing channel 202 to the second wire passing channel 203. During the rotation of the second arm body 220 relative to the first arm body 210 around the first axis 201, the first wire passing channel 202 and the second wire passing channel 203 are always communicated.

[0126] It can be understood that during the rotation of the second arm body 220 relative to the first arm body 210 around the first axis 201, the first wire passing channel 202 and the second wire passing channel 203 are always communicated, which is convenient for the transmission cable 400 to extend through the first wire passing channel 202 to the second wire passing channel 203.

[0127] It should be understood that during the rotation of the second arm body 220 relative to the first arm body 210 around the first axis 201, the transmission cable 400 may be attached to the cavity walls of the first wire passing channel 202 and the second wire passing channel 203, and the first wire passing channel 202 or the second wire passing channel 203 may cause the transmission cable 400 to undergo adaptive deformation, and the first wire passing channel 202 or the second wire passing channel 203 will not destructively squeeze the transmission cable 400.

[0128] It can be understood that the transmission cable 400 extends in the first wire passing channel 202 and the second wire passing channel 203, making the structure of the terminal bracket more compact and occupying a small volume.

[0129] In some implementation manners of the embodiments of the present utility model, with reference to Figures 1 - 42 or Figures 43 - 47 , the first arm body 210 includes a first arm main body 211 and a first rotation limiting portion 212 provided on the first arm main body 211. The first wire passing channel 202 extends to the first arm main body 211. The second arm body 220 includes a second arm main body 221 and a second rotation limiting portion provided on the second arm main body 221. The second wire passing channel 203 extends to the second arm main body 221. The first rotation limiting portion 212 has a first limiting wall 212a and a second limiting wall 212b. 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 abuts against the third limiting wall 222a. After the second arm body 220 rotates a first maximum rotation angle relative to the first arm body 210, the second limiting wall 212b abuts against the fourth limiting wall 223a.

[0130] It can be understood that the first rotation limiting portion 212 and the second rotation limiting portion enable the rotation angle of the second arm body 220 relative to the first arm body 210 around the first axis 201 not to exceed the first maximum rotation angle, thereby avoiding excessive torsion and damage of the transmission cable 400.

[0131] Exemplarily, the first rotation limiting portion 212 is provided on the outer surface of the first arm main body 211, and the second rotation limiting portion is provided on the outer surface of the second arm main body 221.

[0132] In other examples, the first rotation limiting portion 212 is built in the first arm main body 211, and the second rotation limiting portion is built in the second arm main body 221.

[0133] Exemplarily, the first rotation limiting portion 212 is a first protrusion 212. The first rotation limiting portion 212 is located between the third limiting wall 222a and the fourth limiting wall 223a. The first limiting wall 212a and the second limiting wall 212b are respectively located on opposite sides of the first protrusion 212.

[0134] 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.

[0135] It can be understood that during the use of the terminal bracket, the second arm body 220 can be in an intermediate state, that is, a state where the first limiting wall 212a does not abut against the third limiting wall 222a and the second limiting wall 212b does not abut against the fourth limiting wall 223a.

[0136] In some implementation manners of the embodiments of the present utility model, with reference to Figures 1 - 42, the first rotation limiting part 212 is a first protrusion 212 provided on the first arm main body 211, and a first limiting wall 212a and a 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 main body 221, a third limiting wall 222a is located on the second protrusion 222, and a fourth limiting wall 223a is located on the third protrusion 223; the first protrusion 212 protrudes from the outer side wall of the first arm main body 211, and both the second protrusion 222 and the third protrusion 223 protrude from the outer side wall of the second arm main body 221, and the outer side wall of the first arm main body 211 surrounds the first axis 201, and the outer side wall of the second arm main body 221 surrounds the first axis 201.

[0137] Understandably, by providing the first protrusion 212 on the outer side wall of the first arm main body 211, and providing the second protrusion 222 and the third protrusion 223 on the outer side wall of the second arm main body 221, 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 main 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. Thus, 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.

[0138] Exemplarily, the first limiting wall 212a and the second limiting wall 212b are located on opposite sides of the first protrusion 212.

[0139] Understandably, in the initial state, the first protrusion 212 abuts against the second protrusion 222. After the second arm body 220 rotates a first maximum rotation angle relative to the first arm body 210, the first protrusion 212 abuts against the third protrusion 223.

[0140] For example, the second protrusion 222 and the third protrusion 223 are respectively located on opposite sides of the second arm main body 221. After the second arm body 220 rotates 180° relative to the first arm body 210 in the initial state, the first protrusion 212 abuts against the third protrusion 223.

[0141] In some implementation manners of the embodiment of the present utility model, refer to Figures 1 - 42, the first protrusion 212 has a first convex plate 2121 and a first convex rib 2122 protruding from the first convex plate 2121. The first limiting wall 212a and the second limiting wall 212b are respectively located on opposite sides of the first convex rib 2122. The first convex rib 2122 extends along the surface of the first convex plate 2121. Both the first convex rib 2122 and the first convex plate 2121 extend towards the outer space of the second arm body 221. The first convex rib 2122 is located between the first convex plate 2121 and the outer wall of the second arm body 221; the second protrusion 222 has a second convex rib 2221, and the third limiting wall 222a is located on the second convex rib 2221. In a state where the first limiting wall 212a abuts against the third limiting wall 222a, the second convex rib 2221 is located between the first convex plate 2121 and the outer wall of the second arm body 221; the third protrusion 223 has a third convex rib 2231, and the fourth limiting wall 223a is located on the third convex rib 2231. In a state where the second limiting wall 212b abuts against the fourth limiting wall 223a, the third convex rib 2231 is located between the first convex plate 2121 and the outer wall of the second arm body 221.

[0142] It can be understood that the first convex rib 2122 protrudes from the first convex plate 2121 and extends along the surface of the first convex plate 2121, which improves the structural strength of the first convex rib 2122 and makes it not easily damaged during the process of the first convex rib 2122 abutting against the third limiting wall 222a and the fourth limiting wall 223a.

[0143] It can be understood that the first convex rib 2122 is located between the first convex plate 2121 and the outer wall of the second arm body 221, and the third convex rib 2231 is located between the first convex plate 2121 and the outer wall of the second arm body 221, so that the first convex 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, making it not easy to pinch the user's hand during the process of the first limiting wall 212a abutting against the third limiting wall 222a and the second limiting wall 212b abutting against the fourth limiting wall 223a.

[0144] It can be understood that the first convex rib 2122 is located between the first convex plate 2121 and the outer wall of the second arm body 221, and the third convex rib 2231 is located between the first convex plate 2121 and the outer wall of the second arm body 221, making the structure of the connecting arm 200 more compact.

[0145] In some implementation manners of the embodiment of the present utility model, referring to Figures 1 - 42, the first protrusion 212 further has a first boss 2123 protruding from the outer side wall of the first arm body 211. Both the first rib 2122 and the first plate 2121 are 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 rib 2122 and the outer side wall of the second arm body 221; the second protrusion 222 further has a second boss 2222 protruding from the outer side wall of the first arm body 211. The second rib 2221 protrudes from the second boss 2222, and the second rib 2221 extends along the surface of the second boss 2222. In the state where the first limiting wall 212a abuts against the third limiting wall 222a, the second boss 2222 is located within the first gap 204, and the first rib 2122 is close to the second boss 2222; the third protrusion 223 further has a third boss 2232 protruding from the outer side wall of the first arm body 211. The third rib 2231 protrudes from the third boss 2232, and the third rib 2231 extends along the surface of the third boss 2232. In the state where the second limiting wall 212b abuts against the fourth limiting wall 223a, the third boss 2232 is located within the first gap 204, and the first rib 2122 is close to the third boss 2232.

[0146] It can be understood that there is always a first gap 204 between the first rib 2122 and the outer side wall of the second arm body 221, which avoids interference between the first rib 2122 and the outer side wall of the second arm body 221 during the rotation of the second arm body 220 relative to the first arm body 210.

[0147] It can be understood that both the first rib 2122 and the first plate 2121 are connected to the first boss 2123, which improves the structural strength of the first rib 2122.

[0148] It can be understood that the second rib 2221 protrudes from the second boss 2222 and extends along the surface of the second boss 2222, which improves the structural strength of the second rib 2221. And in the state where the first limiting wall 212a abuts against the third limiting wall 222a, the second boss 2222 is located within the first gap 204, making the structure of the connecting arm 200 more compact.

[0149] It can be understood that the third rib 2231 protrudes from the third boss 2232 and extends along the surface of the third boss 2232, which improves the structural strength of the third rib 2231. And in the state where the second limiting wall 212b abuts against the fourth limiting wall 223a, the third boss 2232 is located within the first gap 204, making the structure of the connecting arm 200 more compact.

[0150] In some implementation manners of the embodiment of the present utility model, referring to Figures 1 - 42 , or Figures 43 - 47, the first arm body 210 includes a first arm main body 211 and a first rotating portion 213 provided on the first arm main body 211. The second arm body 220 includes a second arm main body 221 and a second rotating portion 224 provided on the second arm main body 221. The second rotating portion 224 is rotationally engaged with the first rotating portion 213 to enable the second arm body 220 to rotate relative to the first arm body 210 about a first axis 201. A first wire passing channel 202 extends from the first arm main body 211 to the first rotating portion 213, and a second wire passing channel 203 extends from the second arm main body 221 to the second rotating portion 224. The first rotating portion 213 is a rotary groove, and the second rotating portion 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. The first wire passing opening 202a is located at the end of the first rotating portion 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. The second wire passing opening 203a is located at the end of the second rotating portion 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 in communication.

[0151] Understandably, on the one hand, the first rotating portion 213 and the second rotating portion 224 facilitate the rotational installation of the second arm body 220 on the first arm body 210. On the other hand, they also facilitate the setting of the first wire passing opening 202a and the second wire passing opening 203a so that the transmission cable 400 extends from the first arm body 210 to the second arm body 220.

[0152] Understandably, by arranging the first wire passing opening 202a at the end of the first rotating portion 213 and the second wire passing opening 203a at the end of the second rotating portion 224, the transmission cable 400 is close to the first axis 201 when passing through the first rotating portion 213 and the second rotating portion 224, so that the deformation of the transmission cable 400 during the rotation following the second arm body 220 or the first arm body 210 is relatively small.

[0153] In other examples, the first rotating portion 213 is a rotary protrusion, and the second rotating portion 224 is a rotary groove.

The first connecting column 225a protrudes from the second arm main body 221. The first arm main 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 portion 224 from detaching from the first rotating portion 213.

On the one hand, it is convenient to arrange the first connecting column 225a and the first connecting member 225b without hindering the first rotating portion 213 and the second rotating portion 224. On the other hand, it is convenient to make the structure of the first connecting column 225a and the first connecting member 225b compact.

[0156] 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, and during the rotation of the second arm body 220 relative to the first arm body 210 around the first axis 201, the deformation of the transmission cable 400 is small.

The connecting ribs 226 are located in the installation cavity 205, and both 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 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.

[0163] It can be understood that the connecting ribs 226 are connected to the second rotating portion 224 and the first connecting column 225a, enhancing the structural strength of the second rotating portion 224 and the first connecting column 225a.

[0164] It can be understood that the transmission cable 400 passes through the space between the two first connecting sub-ribs 226a, avoiding the influence of the connecting ribs 226 on the passing of the transmission cable 400.

[0165] It can be understood that

[0166] Exemplarily, the number of the connecting ribs 226 is two, three, four, etc.

[0167] In other examples, the number of the connecting ribs 226 is one.

[0168] It can be understood that the two adjacent first connecting sub-ribs 226a means that there are no other connecting ribs 226 between the two first connecting sub-ribs 226a.

Two ends of each connecting rib 226 are respectively connected to the second rotating part 224 and the first connecting column 225a; the number of the connecting ribs 226 is at least two, and at least two connecting ribs 226 include two adjacent second connecting sub-ribs 226b. The first arm body 210 includes a first rotation limiting part 212 arranged on the first arm main body 211, and the second arm body 220 includes a second rotation limiting part arranged on the second arm main body 221. The first rotation limiting part 212 has a first limiting wall 212a and a second limiting wall 212b, and the second rotation limiting part has a third limiting wall 222a and a fourth limiting wall 223a. In the initial state, the first limiting wall 212a abuts against the third limiting wall 222a, and after the second arm body 220 rotates a first maximum angle relative to the first arm body 210, the second limiting wall 212b abuts against the fourth limiting wall 223a; the first rotation limiting part 212 is located between the two second connecting sub-ribs 226b. The first rotation limiting part 212 is a protrusion protruding from the first arm main body 211, and the first rotation limiting part 212 extends into the installation cavity 205; the second rotation limiting part 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.

[0170] 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 the second rotation limiting part (that is, the third limiting wall 222a and the fourth limiting wall 223a are respectively located on the two second connecting sub-ribs 226b), making the structure of the connecting arm 200 compact.

[0171] It can be understood that the first rotation limiting part 212 is a protrusion protruding from the first arm main body 211, and the first rotation limiting part 212 extends into the installation cavity 205, making the structure of the connecting arm 200 compact.

[0172] Exemplarily, the first connecting sub-rib 226a and the second connecting sub-rib 226b are different connecting ribs 226, or the first connecting sub-rib 226a and the second connecting sub-rib 226b are the same connecting rib 226.

[0173] It can be understood that the two adjacent second connecting sub-ribs 226b means that there are no other connecting ribs 226 between the two second connecting sub-ribs 226b.

[0174] In some implementation manners of the embodiment of the present utility model, refer to Figures 1 - 42 , or Figures 43 - 47, the second arm body 220 can be held on the first arm body 210.

The damping ring 230 is sleeved on the second rotating part 224, and 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 held on the first arm body 210.

[0175] Understandably, the second arm body 220 can be held on the first arm body 210, so that the second arm body 220 can be held at a certain position relative to the first arm body 210, thereby enabling the photographing terminal 700 to be held at a position for the user to use.

[0176] Understandably, the damping ring 230 is in interference fit with the second rotating part 224, and the damping ring 230 is in interference fit with the first rotating part 213, so that there is frictional damping between the first rotating part 213 and the second rotating part 224.

[0177] Exemplarily, the damping ring 230 can be made of an elastomeric polymer material, such as rubber, plastic, etc.

[0178] In other examples, the first rotating part 213 and the second rotating part 224 are directly or indirectly in interference fit, so that there is frictional damping between the first rotating part 213 and the second rotating part 224, and the second arm body 220 can be held on the first arm body 210.

[0179] In other examples, the connecting arm 200 has a third fastener (for example, the third fastener is a threaded part or a riveted part). The third fastener makes there be frictional damping between the first rotating part 213 and the second rotating part 224 so that the second arm body 220 can be held on the first arm body 210. For example, the third fastener passes through the second arm body 220 and then makes frictional contact with the first arm body 210.

[0180] In some implementation manners of the embodiments of the present invention, refer to Figures 1 - 42 , or Figures 43 - 47, the first arm body 210 includes a first arm main body 211 and a first rotating portion 213 provided on the first arm main body 211. The second arm body 220 includes a second arm main body 221 and a second rotating portion 224 provided on the second arm main body 221.

The first wire passing channel 202 extends to the first arm main body 211 and the first rotating portion 213, and the second wire passing channel 203 extends to the second arm main body 221 and the second rotating portion 224. The first arm body 210 further includes a first rotation limiting portion 212 provided on the first arm main body 211, and the second arm body 220 is provided with a second rotation limiting portion on the second arm main body 221. In the initial state, the first rotation limiting portion 212 abuts against the second rotation limiting portion. After the second arm body 220 rotates a first maximum angle relative to the first arm body 210, the first rotation limiting portion 212 abuts against 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 abuts against the third limiting wall 222a. After the second arm body 220 rotates a first maximum angle relative to the first arm body 210, the second limiting wall 212b abuts against the fourth limiting wall 223a. The second rotating portion 224 is provided with an installation cavity 205. The second rotation limiting portion is connected to the second rotating portion 224. The second rotation limiting portion 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 portion 212 is a protrusion protruding from the first arm main body 211. The first rotation limiting portion 212 is located between the third limiting wall 222a and the fourth limiting wall 223a, and the first rotation limiting portion 212 extends into the installation cavity 205.

[0182] In some implementation manners of the embodiments of the present invention, with reference to Figures 1 - 42, the support assembly includes a support member 100 and a pan-tilt assembly 500. The pan-tilt assembly 500 is mounted 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 mounted on the support member 100. The rotating body 520 is rotatably mounted 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. The driving assembly 530 is configured to drive the rotating body 520 to rotate relative to the fixed body 510; the first arm body 210 is mounted on the rotating body 520. The transmission cable 400 extends from the first arm body 210 to the receiving cavity 501. The transmission cable 400 is electrically connected to the driving assembly 530; the rotating body 520 is provided with a third wire passing channel 502. The third wire passing channel 502 communicates with the receiving cavity 501. The transmission cable 400 extends to the receiving cavity 501 through the third wire passing channel 502; the first arm body 210 is rotatably mounted on the rotating body 520 about a second axis 902. The second maximum rotation angle of the first arm body 210 relative to the rotating body 520 about the second axis 902 is less than or equal to 270°;

[0183] During the rotation of the first arm body 210 relative to the rotating body 520, the first wire passing channel 202 and the third wire passing channel 502 are always in communication; the terminal bracket further includes a battery 240. The second arm body 220 is provided with a receiving cavity 206. The battery 240 is received in the receiving cavity 206. The transmission cable 400 is configured to transmit the electrical energy of the battery 240 to the driving assembly 530.

[0184] It can be understood that the first arm body 210 is mounted on the rotating body 520. During the rotation of the rotating body 520 relative to the fixed body 510, the first arm body 210 rotates with the rotating body 520, thereby adjusting the position of the shooting terminal 700.

[0185] It can be understood that the transmission cable 400 is configured to transmit signals and / or electrical energy to the driving assembly 530. For example, the transmission cable 400 transmits signals to the driving assembly 530 to control the operation of the driving assembly 530. For example, the transmission cable 400 transmits electrical energy to the driving assembly 530 to enable the driving assembly 530 to continuously move.

[0186] Exemplarily, the driving assembly 530 is a motor or the like.

[0187] Exemplarily, the driving assembly 530 is a motor. The driving assembly 530 includes a motor body 531 and an output shaft 532. The motor body 531 is mounted on the fixed body 510. The output shaft 532 directly drives the rotating body 520. The transmission cable 400 is electrically connected to the motor body 531.

[0188] Exemplarily, the driving component 530 is a motor. The driving component 530 includes a motor main body 531 and an output shaft 532. The motor main body 531 is mounted on the rotating main body 520, and the output shaft 532 is in transmission connection with the fixed main body 510.

[0189] Exemplarily, the third wire passing channel 502 communicates 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.

[0190] The advantage of this setting is that the second maximum rotation angle is less than or equal to 270°, which avoids the multi-turn rotation of the first arm body 210 relative to the rotating main body 520, thereby avoiding the damage of the transmission cable 400 due to excessive torsion.

[0191] Exemplarily, the second maximum rotation angle is 270°, 240°, 210°, 180°, 150°, 120°, 90°, etc.

[0192] It can be understood that during the rotation of the first arm body 210 relative to the rotating main body 520, the first wire passing channel 202 and the third wire passing channel 502 are always in communication, facilitating the transmission cable 400 to extend from the first wire passing channel 202 to the third wire passing channel 502.

[0193] It should be understood that during the rotation of the first arm body 210 relative to the pan-tilt assembly 500 about the first axis 201, the transmission cable 400 may adhere to the cavity walls of the first wire passing channel 202 and the third wire passing channel 502. The first wire passing channel 202 or the third wire passing channel 502 may cause the transmission cable 400 to undergo adaptive deformation, and the first wire passing channel 202 or the third wire passing channel 502 will not squeeze the transmission cable 400 destructively.

[0194] It can be understood that the transmission cable 400 extends in the first wire passing channel 202 and the third wire passing channel 502, making the structure of the terminal bracket more compact and occupying less volume.

[0195] It can be understood that the battery 240 and the driving component 530 are respectively accommodated in the accommodating cavity 206 and the accommodating cavity 501. On the one hand, it avoids the damage of the driving component 530 caused by the destructive damage (such as bulging, leakage, explosion, etc.) of the battery 240. On the other hand, it avoids the volume of the battery 240 being limited by the driving component 530, the rotating main body 520, etc., enabling the volume of the battery 240 to be larger, and thus the capacity of the battery 240 to be larger.

[0196] In some implementation manners of the embodiments of the present utility model, with reference to Figures 1 - 42, the rotating body 520 has a fifth limiting wall 503 and a sixth limiting wall 504.

The first fastener 610 passes through the connecting head 521a and the extension strip 214 so that the extension strip 214 is rotatably mounted on the connecting head 521a around the second axis 902. The first fastener 610 is also used to make there be frictional damping between the extension strip 214 and the connecting head 521a; one of the at least one extension strip 214 is a first extension sub-strip 214a.

[0197] Understandably, the fifth limiting wall 503 and the sixth limiting wall 504 prevent the first arm body 210 from rotating relative to the pan-tilt assembly 500 by more than the second maximum rotation angle, thus avoiding excessive torsion and damage of the transmission cable 400.

The third wire passing opening 202b is arranged on the side surface of the first extension 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 surface of the connecting head 521a. During the rotation of the first arm body 210 relative to the rotating body 520, the third wire passing opening 202b and the fourth wire passing opening 502a are always communicated; the first extension 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.

[0206] 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 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; the advantage of such a setting is that during the rotation of the first arm body 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 following the first arm body 210 (or the pan-tilt assembly 500) is relatively small.

[0207] It can be understood that the third wire passing opening 202b is set as a partial annular opening surrounding the first mounting protrusion 214c, so that the third wire passing opening 202b can easily avoid the transmission cable 400 during the rotation of the first arm body 210 relative to the pan-tilt assembly 500, and the transmission cable 400 is not easily damaged.

[0208] Understandably, the fourth wire-passing opening 502a is provided as a partial annular opening surrounding the second mounting protrusion 521d, so that the fourth wire-passing opening 502a can easily avoid the transmission cable 400 during the rotation of the first arm body 210 relative to the pan-tilt assembly 500, and the transmission cable 400 is not easily damaged.

[0209] Exemplarily, the partial annular opening refers to a section of the annular opening, and the partial annular opening can be a section of the circular annular opening.

[0210] Exemplarily, the partial annular opening is a sector ring type, a waist ring type, etc.

[0211] Understandably, setting the third wire-passing opening 202b as a partial annular opening also facilitates the connection of the first mounting protrusion 214c to other parts of the first extension strip 214a, and setting the fourth wire-passing opening 502a as a partial annular opening also facilitates the connection of the second mounting protrusion 521d to other parts of the connector 521a.

[0219] Understandably, when in the follow-up shooting state, the rotation speed of the rotating body 520 is related to the moving speed of the tracked subject.

[0220] In other examples, the driving assembly 530 is driven by other means, such as directly driving the driving assembly 530 through the control main board 250.

[0221] Understandably, mounting the follow-up camera 260 on the second arm body 220 makes the follow-up camera 260 closer to the shooting lens 710 of the shooting terminal 700, facilitating the shooting lens 710 to shoot the tracked object.

[0222] Exemplarily, the control main board 250 and the follow-up camera 260 are both accommodated in the accommodation cavity 206 of the second arm body 220.

[0239] Specifically, the first inner housing 522 divides the accommodation cavity 501 into a first accommodation sub-cavity 501a and a second accommodation sub-cavity 501b. The motor main body 531 is located in the first accommodation sub-cavity 501a. The third wire passing channel 502 communicates with the first accommodation sub-cavity 501a.

The plugging column 511 and the plugging hole 104 are in interference fit.

[0243] In some implementation manners of the embodiment of the present utility model, refer to Figures 1 - 42, the first arm body 210 is rotatably mounted on the support assembly about the second axis 902, and the first arm body 210 can be rotated about the second axis 902 to a first position relative to the support assembly; the support assembly includes a support member 100, the support member 100 includes a support base 110 and a support rod 120, the support base 110 can be supported on a support surface 901, the support rod 120 is mounted on the support base 110, and the support rod 120 has a central axis 101; in a state where the support base 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 rotating relative to the first arm body 210 about the first axis 201 can make the carrier 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.

[0244] Understandably, in the case where the stability of the support rod 120 is poor (for example, in the case where the support rod 120 is prone to shaking), the second arm body 220 rotating relative to the first arm body 210 about the first axis 201 can make the carrier 300 and the shooting terminal 700 close to the central axis 101, thereby making the terminal bracket more stable.

[0245] Understandably, in the case where the stability of the support rod 120 is good (for example, in the case where the support rod 120 is not prone to shaking), the second arm body 220 rotating relative to the first arm body 210 about the first axis 201 can make the carrier 300 and the shooting terminal 700 away from the central axis 101, so that the use range of the shooting terminal 700 is wider.

[0246] Exemplarily, the support base 110 includes at least three feet 112, the at least three feet 112 can be supported on the support surface 901, and the at least three feet 112 are used to support the support rod 120.

[0247] One implementation of at least three feet 112. The support base 110 includes a support column 111 and at least three feet 112. The support rod 120 is installed on the support column 111, and the feet 112 are rotatably installed on the support column 111. The at least three feet 112 can be opened relative to the support column 111, and the at least three feet 112 are maintained in an open state relative to the support column 111, so that the at least three feet 112 can support on the support surface 901; the feet 112 have a rotation axis rotatably installed on the support column 111, the feet 112 have a resisting end and a supporting end, and the rotation axis is located between the resisting end and the supporting end. The support base 110 further includes a resisting member 113 movably installed on the support column 111. In the state where the at least three feet 112 are opened relative to the support column 111, the resisting member 113 is toggled so that the resisting end of the feet 112 abuts against the resisting member 113, so that the supporting end of the feet 112 can support on the support surface 901. Specifically, the resisting member 113 is rotatably installed on the support column 111, the resisting member 113 has avoiding grooves 103 corresponding to the at least three feet 112, and the resisting member 113 has a resisting portion 113a corresponding to the at least three feet 112. When the resisting member 113 is at the fifth position of the support column 111, the feet 112 rotate relative to the support column 111, and the avoiding grooves 103 are used to avoid the feet 112; when the feet 112 are opened relative to the support column 111 and the resisting member 113 is at the sixth position of the support column 111, the feet 112 can abut against the resisting portion 113a of the resisting member 113. The feet 112 rotate relative to the support column 111, so that the at least three feet 112 can be received in the support column 111. Specifically, the support column 111 is provided with at least three receiving grooves 102, the at least three feet 112 respectively correspond to the at least three receiving grooves 102, and the at least three feet 112 can be received in the at least three receiving grooves 102; in the state where the at least three feet 112 are all received in the support column 111, the support column 111 and the at least three feet 112 can be held by the user.

[0248] Another implementation of at least three feet 112. The support base 110 includes a sliding portion, at least three connecting rods and at least three feet 112. The sliding portion is slidably installed on the support rod 120, the sliding portion can slide along the sliding direction of the support rod 120, the at least three connecting rods respectively correspond to the at least three feet 112, one end of the connecting rod is rotatably connected to the support rod 120 and the other end is rotatably connected to the corresponding foot 112, and the at least three feet 112 are all rotatably connected to the sliding portion. The sliding of the sliding portion relative to the support rod 120 can cause the at least three feet 112 to open or close. In the state where the at least three feet 112 are opened, the at least three feet 112 can support on a support surface 901; in the state where the at least three feet 112 are closed, the at least three feet 112 can be held by the user.

[0249] Exemplarily, the support rod 120 is a telescopic rod or a rod with a fixed length; specifically, the support rod 120 is a telescopic rod, and telescoping the support rod 120 can move the pan-tilt assembly 500, the connecting arm 200, the supporting member 300, and the shooting terminal 700 as a whole away from or closer to the support base 110; in a state where 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; in a state where 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.

[0250] Exemplarily, in a state where the support base 110 is supported on the support surface 901, the central axis 101 of the support rod 120 is coaxial with the plumb line of the support assembly, or the included angle between the central axis 101 of the support rod 120 and the plumb line of the support assembly is less than or equal to 5° and the distance between them is less than or equal to 1 cm.

[0251] It can be understood that the stability of an object on the support surface 901 is called the stability degree, and the stability degree of an object is related to its center of gravity height or tipping radius. Specifically, the area surrounded by the contact points of the object on the support surface 901 is called the support surface, and the support surface is a part of the support surface 901. If the intersection point of the plumb line of the object and the support surface 901 is within the support surface, the object will not tip over; the mass distribution of the object is not necessarily uniform, and the surface surrounded by the contact points of the object and the support surface is not necessarily a circular surface. The bottom edge point (line) around which the object may tip over is called the tipping point (line), and the intersection point of the plumb line passing through the center of gravity of the object and the horizontal support surface is called the gravity stability center (the intersection point of the projection surface of the inclined support surface on the horizontal plane passing through the tipping point and the plumb line is the gravity stability center). The distance from the gravity stability center to the tipping point (line) is called the tipping radius. For a general object, when the center of gravity height is constant and the support surface size is constant, the difficulty of tipping over in different directions is different, and the stability degree has directionality. Therefore, the stability degree should be defined as the stability degree of the object on the support surface in a certain direction, which is called its stability degree in this direction. The stability degree of an object in a certain direction is related to the center of gravity height of the object and the tipping radius of the object in this direction.

[0252] It can be understood that the stability degree of an object in a certain direction is inversely proportional to the center of gravity height of the object and directly proportional to the tipping radius of the object.

[0253] Exemplarily, in a state where the support base 110 is supported on the support surface 901 and the first arm body 210 is in a 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, make the plumb line of the terminal bracket and the shooting terminal 700 more centered, make the tipping radius of the terminal bracket and the shooting terminal 700 larger, and make the terminal bracket not easily tip over.

[0254] In some implementation manners of the embodiments of the present utility model, referring to Figures 1 - 42 , in a state where the support base 110 can be supported on a support surface 901, the included angle between the central axis 101 and the plumb line is less than or equal to 5°; the included 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 included 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°; in a state where the first arm body 210 is in a first position relative to the support assembly, the included angle between the first axis 201 and the central axis 101 is less than or equal to 5°; the carrier 300 is rotatably mounted on the second arm body 220, and the relative rotation of the carrier 300 with respect to the second arm body 220 can make the carrier 300 and the shooting terminal 700 located on one side of the first axis 201; the support assembly further includes a pan-tilt assembly 500, the pan-tilt assembly 500 is mounted on the support rod 120, and the first arm body 210 is rotatably mounted on the pan-tilt assembly 500 around the second axis 902.

[0255] It can be understood that, in a state where the first arm body 210 is in a first position relative to the support assembly and the relative rotation of the carrier 300 with respect to the second arm body 220 can make the carrier 300 and the shooting terminal 700 located on one side of the first axis 201, the relative rotation of the second arm body 220 with respect to the first arm body 210 around the first axis 201 can make the carrier 300 and the shooting terminal 700 approach or move away from the central axis 101.

[0256] 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.

[0257] It can be understood that the included angle between the second axis 902 and the central axis 101 being greater than or equal to 85° and less than or equal to 90° makes the second axis 902 perpendicular or nearly perpendicular to the central axis 101, and the included angle between the first axis 201 and the second axis 902 being greater than or equal to 85° and less than or equal to 90° makes the first axis 201 perpendicular or nearly perpendicular to the second direction; the advantage of the above settings is that it is convenient for the shooting terminal 700 to adjust the use direction.

[0258] It can be understood that, in a state where the first arm body 210 is in a first position relative to the support assembly and the carrier 300 and the shooting terminal 700 are located on one side of the first axis 201, the included angle between the first axis 201 and the central axis 101 is less than or equal to 5°, and the relative rotation of the second arm body 220 with respect to the first arm body 210 around the first axis 201 can make the carrier 300 and the shooting terminal 700 closer to the central axis 101 to improve the stability of the terminal bracket. For example, the carrier 300 and the shooting terminal 700 are closer to the central axis 101, making the turning radius of the terminal bracket and the shooting terminal 700 larger on the support surface 901.

[0259] Understandably, the included angle range between two straight lines is from 0° to 90°.

[0260] For example, the included angle between the central axis 101 and the plumb line is 0°, 1°, 2°, 3°, 4°, 5°, etc.

[0261] For example, the included angle between the second axis 902 and the central axis 101 is 85°, 86°, 87°, 88°, 89°, 90°, etc.

[0262] For example, the included angle between the first axis 201 and the second axis 902 is 85°, 86°, 87°, 88°, 89°, 90°, etc.

[0263] For example, in a state where the first arm body 210 is in a first position relative to the support assembly, the included angle between the first axis 201 and the central axis 101 is 0°, 1°, 2°, 3°, 4°, 5°, etc.

[0264] In other examples, the supporting member 300 is fixedly installed on the second arm body 220, and the supporting member 300 and the shooting terminal 700 are located on one side of the first axis 201.

[0266] Understandably, when the terminal bracket is not in use, folding the second arm body 220 on the first side wall 903 can make the occupied volume of the terminal bracket small for easy storage.

[0267] For example, the first side wall 903 is located on the first side wall 903 of the pan-tilt assembly 500.

[0268] In other examples, the first side wall 903 is located on the pan-tilt assembly 500 and the support base 110. For example, the support base 110 includes a support column 111 and at least three support feet 112, and the first side wall 903 is located on the pan-tilt assembly 500 and the support column 111.

[0269] 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 support feet 112, and the first side wall 903 is located on the support column 111.

[0270] In other examples, the support rod 120 has a first side wall 903. For example, the support rod 120 is a telescopic rod, and when the support rod 120 is in a telescopic state, the support rod 120 has a first side wall 903.

[0271] Understandably, the connecting arm 200 being folded onto 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 part of the connecting arm 200 is in contact with or close to the first side wall 903.

[0272] In some implementation manners of the embodiment of the present utility model, referring to Figures 1 - 42 , in a state where the connecting arm 200 is folded onto the first side wall 903, the second arm body 220 is close to or in contact with 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 the second arm body 220 is close to or in contact with the first side wall 903 in a state where the connecting arm 200 is folded onto the first side wall 903; the first arm body 210 includes a first arm main body 211 and at least one extension strip 214, and at least one extension strip 214 protrudes from the first arm main body 211; at least one extension strip 214 is rotatably installed on the supporting assembly, the second arm body 220 has a second arm main body 221, the first arm main body 211 and the second arm main body 221 both extend in a direction parallel to the first axis 201, and the cross-sections of the first arm main body 211 and the second arm main body 221 are the same; in a state where the second arm body 220 is in the third position relative to the first arm body 210, the first arm main body 211 and the second arm main body 221 are aligned so that the first arm main body 211 and the second arm main body 221 are close to or in contact with the first side wall 903 in a state where the connecting arm 200 is folded onto the first side wall 903; in a state where the connecting arm 200 is folded onto the first side wall 903, the second axis 902 and the second arm main body 221 are on both sides of the first side wall 903, and the extension strip 214 is curved so that the first arm main body 211 and the second arm main body 221 are close to or in contact with the first side wall 903 in a state where the connecting arm 200 is folded onto the first side wall 903.

[0273] Understandably, in a state where the connecting arm 200 is folded onto the first side wall 903, the second arm body 220 is close to or in contact with the first side wall 903, and the second arm body 220 is located between the first side wall 903 and the supporting member 300, so that the volume of the terminal bracket during storage is smaller. Specifically, the supporting member 300 is installed on the second arm main body 221 of the second arm body 220, and in a state where the connecting arm 200 is folded onto the first side wall 903, the second arm main body 221 is located between the first side wall 903 and the supporting member 300.

[0274] Exemplarily, in a state where the second arm body 220 is in the third position relative to the first arm body 210, the shape of the connecting arm 200 is adapted to the first side wall 903 so as to facilitate the second arm body 220 to be close to or attached to the first side wall 903. For example, the first side wall 903 extends straight, and in a state where the second arm body 220 is in the third position relative to the first arm body 210, the second arm body 220 is also aligned with the first arm body 210, so that the connecting arm 200 is adapted to the first side wall 903.

[0275] It can be understood that in a state where the second arm body 220 is in the third position relative to the first arm body 210, the first arm main body 211 is aligned with the second arm main body 221, which facilitates the folding of the first arm main body 211 and the second arm main body 221 on the first side wall 903.

[0276] It can be understood that the cross-sectional shapes of the first arm main body 211 and the second arm main body 221 are the same and the extending directions are the same, which facilitates the rotation of the second arm body 220 relative to the first arm body 210 around the first axis 201 so that the first arm main body 211 and the second arm main body 221 can be aligned.

[0277] Exemplarily, the cross-section of the first arm main body 211 is polygonal, rounded rectangular, drum-shaped, etc.

[0278] It can be understood that the first arm main body 211 and the second arm main body 221 are aligned so that in a state where the connecting arm 200 is folded on the first side wall 903, the first arm main body 211 and the second arm main body 221 are close to or attached to the first side wall 903, making the structure of the terminal bracket more compact and occupying a small volume in the storage state.

[0281] In this rotational connection structure, 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°, which avoids multiple rotations of the second arm body 220 relative to the first arm body 210, thereby avoiding excessive torsion of the transmission cable 400 and avoiding damage to the transmission cable 400 caused by excessive torsion of the transmission cable 400.
