DETAILED DESCRIPTION

[0054] The present invention will be described in further detail below with reference to the accompanying drawings.

[0055] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed, but as long as they are within the scope of the claims of the present invention, they are protected by patent law.

[0056] Reference Figures 1-33The embodiment of the present invention proposes a terminal bracket for supporting an electronic terminal, including a support member 10, a pan-tilt assembly 20 and a supporting member 30. The support member 10 is used to support the pan-tilt assembly 20; the pan-tilt assembly 20 includes a fixed assembly 100, a rotating assembly 200 and a bearing assembly 300. The fixed assembly 100 is installed on the support member 10, the rotating assembly 200 is used to support the supporting member 30, and the bearing assembly 300 enables the rotating assembly 200 to rotate around a first rotation axis relative to the fixed assembly 100; the bearing assembly 300 includes a first bearing member 310, a second bearing member 320 and a plurality of first balls 340. The plurality of first balls 340 are rollingly installed on the first bearing member 310 and the second bearing member 320. 0 so that the second carrier 320 can rotate around the first rotation axis relative to the first carrier 310, the first carrier 310 is fixedly installed on the fixed component 100, and the second carrier 320 is fixedly installed on the rotating component 200; the bearing assembly 300 also includes a third carrier 330 and a plurality of second balls 350, the third carrier 330 is fixedly installed on the fixed component 100, the second carrier 320 is located between the first ball 340 and the second ball 350, and the plurality of second balls 350 are rollingly installed between the second carrier 320 and the third carrier 330 so that the second carrier 320 can rotate around the first rotation axis relative to the third carrier 330; the supporting member 30 is used to support the electronic terminal.

[0057] It can be understood that the second bearing member 320 can rotate relative to the first bearing member 310 about the first rotation axis, and the second bearing member 320 can rotate relative to the third bearing member 330 about the first rotation axis. This reduces the slight wobble of the second bearing member 320 relative to the first rotation axis during rotation of the bearing assembly 300, allowing the second bearing member 320 to rotate more stably about the first rotation axis, thereby allowing the rotating assembly 200 to rotate more stably about the first rotation axis. Furthermore, the first bearing member 310 and the third bearing member 330 are both mounted on the fixed assembly 100, while the second bearing member 320 is mounted on the rotating assembly 200. This allows the bearing assembly 300 to rotate the rotating assembly 200 relative to the fixed assembly 100 about the first rotation axis, and allows the rotating assembly 200 to rotate more stably about the first rotation axis relative to the fixed assembly 100, thereby allowing the pan / tilt assembly 200 to rotate more stably about the first rotation axis.

[0058] It can be understood that the rotation component 200 rotates relative to the fixed component 100 around the first rotation axis to change the use angle of the electronic terminal.

[0059] For example, the electronic terminal can be a mobile phone, tablet, camera, etc.;

[0060] It should be understood that the support member 10 has at least one supporting method. For example, the support member 10 can be supported on a supported surface (such as a desktop, the ground, etc.), and the support member 10 has a support plate, or the support member 10 has at least three legs 11, so that the supporting surface can be a supported plane or a supported curved surface. For another example, the support member 10 can be adsorbed on a surface (such as a desktop, a car glass surface, a wall, a car center console, etc.), and the support member 10 has a suction cup portion, and the support member 10 can be adsorbed on the supporting surface. For another example, the support member 10 can be magnetically attracted to a magnetically attracted surface (such as an iron surface, etc.), and the magnetically attracted surface has ferromagnetism or permanent magnetism, and the support member 10 has a magnetic attraction portion, and the magnetic attraction portion is made of a permanent magnetic material. For another example, the support member 10 can be clamped to a clamped object (such as a tabletop, a railing, a bedside, a chair armrest, etc.), and the support member 10 has a clamping portion 32, and the clamped object can be a plate-shaped object or a rod-shaped object. For another example, the support member 10 can be held by a user. When the user holds the support member 10 , the terminal bracket is a selfie bracket.

[0061] Reference Figure 1 、 Figure 31-33 A specific implementation of the support member 10 is that the support member 10 includes a support rod 12, a support body 13, at least three support legs 11 and a locking assembly 14, the support rod 12 is installed on the support body 13, the support rod 12 is a telescopic rod, the pan-tilt assembly 20 is installed on the support rod 12, and the support rod 12 can adjust the distance between the electronic terminal and the support body 13 by telescoping; the support legs 11 are rotatably installed on the support body 13, and the support legs 11 can be opened or retracted relative to the support body 13. When at least three support legs 11 are opened relative to the support body 13, at least three support legs 11 are supported on the supported surface, and when at least three support legs 11 are retracted relative to the support body 13, the support body 13 is convenient for the user to hold. Specifically, the support body 13 is provided with at least three receiving grooves 13a, and the support legs 11 can be folded into the corresponding receiving grooves 13a; the locking assembly 14 is rotatably installed on the support body 13, and the locking assembly 14 has at least three avoidance grooves 14a and at least three abutment walls 14b. When the locking assembly 14 is in a first position relative to the support body 13, the support legs 11 can be opened or folded relative to the support body 13. In the process of opening or folding the support legs 11 relative to the support body 13, the avoidance groove 14a avoids the corresponding support legs 11; when the support legs 11 are open relative to the support body 13, the locking assembly 14 can be rotated to a second position relative to the support body 13. When the support legs 11 are open relative to the support body 13, the locking assembly 14 is in the second position relative to the support body 13, and the support legs 11 are supported on the supported surface, the support legs 11 abut against the corresponding abutment walls 14b.

[0062] Another implementation of the support member 10 is that the support member 10 includes a support rod 12, a sliding sleeve, at least three support legs 11, and at least three connecting rods. The sliding sleeve is slidably installed on the support rod 12 along the length direction of the support rod 12, and each support leg 11 is rotatably installed on the sliding sleeve. The at least three support legs 11 correspond to the at least three connecting rods respectively, and one end of each connecting rod is rotatably installed on the support rod 12, and the other end is rotatably installed on the corresponding support leg 11. The sliding of the sliding sleeve can make the at least three support legs 11 retract or open relative to the support rod 12; when the at least three support legs 11 are open relative to the support rod 12, the at least three support legs 11 can be supported on a supported surface, and when the at least three support legs 11 are retracted relative to the support rod 12, the at least three support legs 11 can be held by the user.

[0063] In some implementations of the present invention, the length of the support member 10 is adjustable or fixed. For example, the support member 10 may further include a support rod 12 to support the electronic terminal at a certain height or distance. The fixing assembly 100 is mounted on the support rod 12. For example, the support rod 12 is a telescopic rod; another example is a flexible rod; another example is a rod of fixed length.

[0064] In some optional implementations, the fixing assembly 100 is fixedly mounted on the support member 10, or the fixing assembly 100 is movably mounted on the support member 10. For example, the fixing assembly 100 has a plug-in post 110, and the support rod 12 of the support member 10 has a plug-in hole 12a. The plug-in post 110 is plugged into the plug-in hole 12a, and the plug-in post 110 and the plug-in hole 12a have an interference fit. Preferably, the fixing assembly 100 is mounted on the top end of the support member 10.

[0065] In some optional implementations, the supporting member 30 is directly or indirectly mounted on the rotating assembly 200. For example, the terminal bracket also includes a connecting arm 50, the connecting arm 50 is mounted on the rotating assembly 200, and the supporting member 30 is mounted on the connecting arm 50. For example, the supporting member 30 is fixedly mounted on the connecting arm 50, or the supporting member 30 is movably mounted on the connecting arm 50.

[0066] For example, the supporting member 30 can have a variety of supporting methods, such as referring to Figure 10The supporting member 30 may be a clamp 30 for clamping the electronic terminal. The clamp 30 includes a clamp body 31 and two clamping parts 32. The two clamping parts 32 are respectively clamped on two opposite sides of the electronic terminal. The clamp body 31 can be elastically extended and retracted to adjust the clamping width of the clamp 30. The clamping parts 32 can be stored in the clamp body 31. For another example, the supporting member 30 is a suction cup for adsorbing the electronic terminal. For example, the suction cup can be adsorbed on the back of the electronic terminal. For another example, the supporting member 30 is a magnetic member for magnetically attracting the electronic terminal. The magnetic member can be an electromagnet or a permanent magnet. For another example, the supporting member 30 is a tray for supporting the electronic terminal, and the electronic terminal is placed on the tray. For another example, the supporting member 30 is a clamping member for clamping the electronic terminal. The clamping member is used to clamp the electronic terminal.

[0067] For example, the bearing assembly 300 and the fixing assembly 100 can be connected in a variety of ways. For example, the first bearing member 310 is directly or indirectly fixedly mounted on the fixing assembly 100. The first bearing member 310 is integrally or detachably fixedly mounted on the fixing assembly 100. Specifically, the pan / tilt assembly 20 further includes a fourth fastener 364. The fourth fastener 364 passes through the fixing assembly 100 and is fastened to the first bearing member 310. The fourth fastener 364 can be a threaded member or a riveted member. For another example, the third carrier 330 is directly or indirectly fixedly installed on the fixing assembly 100, and the third carrier 330 is integrally or detachably fixedly installed on the fixing assembly 100; specifically, the third carrier 330 is directly fixedly installed on the first carrier 310 to achieve the third carrier 330 being fixedly installed on the fixing assembly 100; more specifically, the bearing assembly 300 also includes at least one first fastener 361, which passes through the first carrier 310 and is fastened to the third carrier 330, and the first fastener 361 can be a threaded member or a riveted member.

[0068] For example, the bearing assembly 300 and the rotating assembly 200 can be connected in a variety of ways. For example, the second bearing member 320 is directly or indirectly fixedly mounted on the rotating assembly 200. The second bearing member 320 is integrally or detachably fixedly mounted on the rotating assembly 200. Specifically, the pan / tilt assembly 20 also includes a third fastener 363, which is used to fasten the second bearing member 320 to the rotating assembly 200. The third fastener 363 passes through the second bearing member 320 and is fastened to the rotating assembly 200. The third fastener 363 can be a threaded member or a riveted member.

[0069] It should be understood that the first balls 340 are spherical in shape and are rollingly mounted between the first support member 310 and the second support member 320. The first balls 340 are in rolling contact with both the first support member 310 and the second support member 320. For example, the number of first balls 340 is 2, 3, 4, 5, 6, 7, or 8. Preferably, the plurality of first balls 340 are evenly distributed around the first rotation axis. The second balls 350 are spherical in shape and are rollingly mounted between the second support member 320 and the third support member 330. The second balls 350 are in rolling contact with both the second support member 320 and the third support member 330. For example, the number of second balls 350 is 2, 3, 4, 5, 6, 7, or 8. Preferably, the plurality of first balls 340 are evenly distributed around the first rotation axis.

[0070] It can be understood that in one support mode of the pan / tilt assembly 20, the rotating assembly 200 carries the supporting member 30 and the electronic terminal, the second bearing member 320 carries the rotating assembly 200, the first ball bearing 340 carries the second bearing member 320, the first bearing member 310 carries the first ball bearing 340, and the fixed assembly 100 carries the first bearing member 310. In another support mode of the pan / tilt assembly 20, the fixed assembly 100 carries the supporting member 10, the third bearing member 330 carries the fixed assembly 100, the third bearing member 330 carries the second ball bearing 350, the second ball bearing 350 carries the second bearing member 320, and the rotating assembly 200 carries the second bearing member 320.

[0071] In some implementations of the present invention, referring to Figure 4 、 Figure 24-30 During the rotation of the second carrier 320 relative to the first carrier 310, the first ball 340 rolls relative to the first carrier 310 and the second carrier 320, and the first ball 340 rotates around the first rotation axis to make the second carrier 320 rotate relative to the first carrier 310 around the first rotation axis; during the rotation of the second carrier 320 relative to the third carrier 330, the second ball 350 rolls relative to the second carrier 320 and the third carrier 330, and the second ball 350 rotates around the first rotation axis to make the second carrier 320 rotate relative to the third carrier 330 around the first rotation axis.

[0072] It should be understood that while the first ball 340 rotates about the first rotation axis, causing the second bearing member 320 to rotate relative to the first bearing member 310 about the first rotation axis, the second ball 350 rotates about the first rotation axis, causing the second bearing member 320 to rotate relative to the third bearing member 330 about the first rotation axis. The movement of the first ball 340 also includes rolling, for example, the first ball 340 rolls relative to the first bearing member 310 and the second bearing member 320. The movement of the second ball 350 also includes rolling, for example, the second ball 350 rolls relative to the second bearing member 320 and the third bearing member 330.

[0073] Specifically, refer to Figure 4 、 Figure 24-30 The first bearing member 310 is provided with a plurality of first rolling cavities 301, and a plurality of first balls 340 are respectively rollingly installed in the plurality of first rolling cavities 301. The third bearing member 330 is provided with a plurality of second rolling cavities 302, and a plurality of second balls 350 are respectively rollingly installed in the plurality of second rolling cavities 302. The second bearing member 320 is provided with a first rolling groove 303 and a second rolling groove 304. The first rolling groove 303 is a rotary groove around the first rotation axis, and the second rolling groove 304 is a rotary groove around the first rotation axis. The plurality of first balls 340 are rollingly installed in the first rolling groove 303. A plurality of second balls 350 are rollingly mounted within the second rolling groove 304. During rotation of the second bearing member 320 relative to the first bearing member 310, the first balls 340 roll within the first rolling cavity 301 and within the first rolling groove 303, causing the first balls 340 to rotate about the first rotation axis. During rotation of the second bearing member 320 relative to the third bearing member 330, the second balls 350 roll within the second rolling cavity 302 and within the second rolling groove 304, causing the second balls 350 to roll about the first rotation axis. It can be understood that the rolling of the first balls 340 within the first rolling groove 303 causes the first balls 340 to rotate about the first rotation axis, thereby causing the second bearing member 320 to rotate about the first rotation axis relative to the first bearing member 310. The rolling of the second balls 350 within the second rolling groove 304 causes the second balls 350 to rotate about the second rotation axis, thereby causing the second bearing member 320 to rotate about the first rotation axis relative to the third bearing member 330.

[0074] For example, refer to Figure 4 、 Figure 24-30The first ball 340 is spherical, the first rolling cavity 301 is a partial spherical cavity adapted to the first ball 340, the first rolling groove 303 is a partial toroidal cavity adapted to the first ball 340, and the generatrix of the first rolling groove 303 is an arc-shaped adapted to the first ball 340; the second ball 350 is spherical, the second rolling cavity 302 is a partial spherical cavity adapted to the second ball 350, the second rolling groove 304 is a partial toroidal cavity adapted to the second ball 350, and the generatrix of the second rolling groove 304 is an arc-shaped adapted to the second ball 350. More specifically, the first rolling cavity 301 is a hemispherical cavity or a spherical cap cavity, the second rolling cavity 302 is a hemispherical cavity or a spherical cap cavity, the first rolling groove 303 is a semi-toroidal cavity, and the second rolling groove 304 is a semi-toroidal cavity.

[0075] In some other implementations, multiple first rolling cavities 301 are provided on the second carrier 320, and the first rolling grooves 303 are provided on the first carrier 310. The first rolling grooves 303 are rotating grooves around a first rotation axis. The first balls 340 roll within the first rolling cavities 301. The rolling of the first balls 340 within the first rolling grooves 303 causes the first balls 340 to rotate around the first rotation axis, thereby causing the second carrier 320 to rotate around the first rotation axis relative to the first carrier 310. Alternatively, the second carrier 320 is provided with the first rolling grooves 303, and the first carrier 310 is provided with a third annular groove. Both the first rolling grooves 303 and the third annular groove are rotating grooves around the first rotation axis. The rolling of the first balls 340 within the first rolling grooves 303 and the third annular groove causes the first balls 340 to rotate around the first rotation axis, thereby causing the second carrier 320 to rotate around the first rotation axis relative to the first carrier 310.

[0076] In some other implementations, multiple second rolling cavities 302 are provided on the second support member 320, and second rolling grooves 304 are provided on the third support member 330. The second rolling grooves 304 are rotating grooves circling the first rotation axis. The second balls 350 roll within the second rolling cavities 302. The rolling of the second balls 350 in the second rolling grooves 304 causes the second balls 350 to rotate about the first rotation axis, thereby causing the second support member 320 to rotate about the first rotation axis relative to the third support member 330. Alternatively, the second support member 320 is provided with the second rolling grooves 304, and the third support member 330 is provided with a fourth annular groove. Both the second rolling grooves 304 and the fourth annular groove are rotating grooves circling the first rotation axis. The rolling of the second balls 350 in the second rolling grooves 304 and the fourth annular groove causes the second balls 350 to rotate about the first rotation axis, thereby causing the second support member 320 to rotate about the first rotation axis relative to the third support member 330.

[0077] Further, refer to Figure 4 、 Figure 24-30The third carrier 330 includes a carrier ring 331 and a connecting column 332 connected to the carrier ring 331, and a plurality of second balls 350 are rollingly installed between the second carrier 320 and the carrier ring 331; the second carrier 320 is provided with a first avoidance hole 305, and the connecting column 332 passes through the first avoidance hole 305, and the connecting column 332 is fixedly connected to the first carrier 310 (for example, the connecting column 332 and the first carrier 310 are fastened together by a plurality of first fasteners 361, and the first fastener 361 passes through the first carrier 310 and is fastened together with the connecting column 332); during the rotation of the third carrier 330 relative to the second carrier 320, the connecting column 332 rotates in the first avoidance hole 305. It can be understood that the first avoidance hole 305 facilitates the passage of the first connecting column 332, thereby facilitating the connecting column 332 to achieve a fixed connection between the first supporting member 310 and the third supporting member 330. The setting of the first avoidance hole 305 also makes the structure of the bearing assembly 300 compact and occupies a small volume.

It can be understood that the first fastener 361 fixes the connecting column 332 to the first carrier 310, and the first fastener 361 can be a screw, a rivet, etc.; the first plug-in portion 311 is circumferentially fixed around the first rotation axis relative to the second plug-in portion 333, so that the connecting column 332 can transmit the rotational torque to the first carrier 310, and avoid the first fastener 361 from receiving too much rotational torque and causing the first fastener 361 to loosen; and during the installation process, the cooperation between the first plug-in portion and the second plug-in portion can also make the first through hole 306b aligned with the first fastening hole 306a.

[0079] In some implementations of the present invention, referring to Figure 4 、 Figures 19-30The pan-tilt assembly 20 also includes a driving assembly 400, which is used to drive the rotating assembly 200 to rotate relative to the fixed assembly 100 around the first rotation axis; the driving assembly 400 includes a motor body 410 and an output shaft 420, the output shaft 420 is rotatably mounted on the motor body 410 around the first rotation axis, and the motor body 410 is fixedly mounted on the rotating assembly 200; the output shaft 420 is circumferentially fixed around the first rotation axis relative to the third carrier 330, the output shaft 420 has a mating protrusion 421, the connecting column 332 is provided with a mating groove 307, and the mating protrusion 421 is circumferentially fixed around the first rotation axis relative to the mating groove 307. It can be understood that during the rotation of the output shaft 420 relative to the motor body 410, the motor body 410, the rotating assembly 200 and the second carrier 320 rotate as a whole relative to the fixed assembly 100 around the first rotation axis, and the mating groove 307 is provided on the connecting column 332, so that the structure of the bearing assembly 300 is compact and occupies a small volume; and the mating groove 307 and the mating protrusion 421 cooperate to realize the transmission of the rotational torque from the output shaft 420 to the third carrier 330; because the connecting column 332 passes through the first avoidance hole 305, the mating groove 307 is convenient to extend a longer length, so that the mating groove 307 is not easily deformed when subjected to the rotational torque.

[0080] For example, the driving component 400 can be a stepping motor, a servo motor, etc.

[0081] In some other implementations, the output shaft 420 is provided with a matching groove 307 , and the connecting column 332 is provided with a matching protrusion 421 , so that the output shaft 420 is circumferentially fixed relative to the third bearing member 330 around the first rotation axis.

[0082] In some other implementations, the output shaft 420 is directly fixedly mounted on the third bearing member 330 and / or the first bearing member 310 .

[0083] In some other implementations, the pan-tilt assembly 20 is a manual pan-tilt assembly that requires the user's hand movements to operate so that the rotating assembly 200 rotates relative to the fixed assembly 100.

[0084] In some implementations of the present invention, referring to Figure 4 、 19-30, the pan-tilt assembly 20 also includes a drive assembly 400, which is used to drive the rotating assembly 200 to rotate relative to the fixed assembly 100 around the first rotation axis; the drive assembly 400 includes a motor body 410 and an output shaft 420, the output shaft 420 is rotatably mounted on the motor body 410 around the first rotation axis, and the motor body 410 is fixedly mounted on the rotating assembly 200; the output shaft 420 is circumferentially fixed around the first rotation axis relative to the third bearing member 330; the rotating assembly 200 includes a first outer shell 210 and a first inner shell 220, the first inner shell 220 is fixedly mounted on the first outer shell 210, and the first outer shell 210 surrounds and forms a first cavity The body 201, the first inner shell 220, the bearing assembly 300, and the drive assembly 400 are all accommodated in the first cavity 201, and the bearing assembly 300 and the motor body 410 are respectively located on opposite sides of the first inner shell 220; the motor body 410 is fixedly installed on the first inner shell 220, and the second bearing member 320 is fixedly installed on the first inner shell 220.

As can be understood, the first inner housing 220 facilitates the installation of the motor body 410 and the second bearing member 320. Furthermore, the bearing assembly 300 and the drive assembly 400 are located on opposite sides of the first inner housing 220, resulting in a compact structure for the pan-tilt head assembly 20. The provision of the first through-hole 202 also provides a benefit by preventing the first inner housing 220 from obstructing the circumferential fixed fit between the output shaft 420 and the third bearing member 330. This allows the bearing assembly 300 and the drive assembly 400 to be located on opposite sides of the first inner housing 220, further enhancing the compact structure of the pan-tilt head assembly 20. The bearing ring 331 of the third bearing member 330 is located between the first inner housing 220 and the second bearing member 320, resulting in a compact structure and a small footprint for the pan-tilt head assembly 20. Clearly, there is space between the first inner housing 220 and the second bearing member 320 for the bearing ring 331 to rotate.

[0085] Specifically, refer to Figure 4 、 19-30, the pan-tilt assembly 20 also includes a second fastener 362, which is used to fasten the first inner shell 220 to the first outer shell 210. Specifically, the second fastener 362 passes through the first inner shell 220 and is fastened to the first outer shell 210. The second fastener 362 may be a screw or a rivet.

[0087] In some implementations of the present invention, referring to Figure 4 、 19 -30, the pan-tilt assembly 20 also includes a first locking member 500, which is slidably mounted on the rotating assembly 200, and the first locking member 500 has a first locking portion 510; the first supporting member 310 has a second locking portion 312 that can cooperate with or disengage from the first locking portion 510, and when the first locking portion 510 and the second locking portion 312 are cooperated, the rotating assembly 200 is locked to the fixed assembly 100; the first locking portion 510 is a first tooth 510 extending along the sliding direction of the first locking member 500, and the number of the first tooth 510 is at least 1, and the second locking portion 312 is a plurality of tooth grooves 312, and the plurality of tooth grooves 312 are evenly arranged around the first rotation axis, the first tooth 510 is adapted to the tooth groove 312, and the first locking member 500 slides relative to the rotating assembly 200 to allow the first tooth 510 to be inserted into or disengaged from the tooth groove 312. It can be understood that the second locking portion 312 is provided on the first supporting member 310, so that the bearing assembly 300 is used to realize the rotational connection between the rotating assembly 200 and the fixed assembly 100, and is also used to lock the rotating assembly 200 to the fixed assembly 100, so that the structure of the pan-tilt assembly 20 is compact.

[0088] In some implementations of the present invention, referring to Figure 4 、 19 -30, the pan-tilt assembly 20 also includes a drive assembly 400, which is used to drive the rotating assembly 200 to rotate around the first rotation axis relative to the fixed assembly 100; the drive assembly 400 includes a motor body 410 and an output shaft 420, the output shaft 420 is rotatably mounted on the motor body 410 around the first rotation axis, and the motor body 410 is fixedly mounted on the rotating assembly 200; the output shaft 420 is circumferentially fixed around the first rotation axis relative to the third carrier 330.

[0089] Further, refer to Figure 11-19The terminal bracket also includes a connecting arm 50 and a transmission cable 40. The transmission cable 40 is used to transmit signals and / or electrical energy. The transmission cable 40 is electrically connected to the driving assembly 400. The supporting member 30 is installed on the connecting portion. The connecting arm 50 is rotatably installed on the rotating assembly 200. The rotating assembly 200 has a first cavity 201. The first cavity 201 is used to accommodate the driving assembly 400 and the bearing assembly 300. The connecting arm 50 includes a first arm body 51 and a second arm body 52. The first arm body 51 is rotatably installed on the rotating assembly 200. The second arm 52 is rotatably mounted on the first arm 51 around the first axis, the supporting member 30 is mounted on the second arm 52, the transmission cable 40 is mounted on the first arm 51, the transmission cable 40 extends from the first arm 51 to the second arm 52, the transmission cable 40 extends from the first arm 51 to the first cavity 201 of the rotating assembly 200, the second arm 52 is provided with a receiving cavity 52b, the transmission cable 40 extends to the receiving cavity 52b, the terminal bracket further includes a battery 61, the battery 61 is electrically connected to the transmission cable 40, the battery 61 is accommodated in the accommodating cavity 52b; the first arm 51 is provided with a first wire-passing channel 51a, and the second arm 52 is provided with a second wire-passing channel 52a. The transmission cable 40 extends from the first wire-passing channel 51a to the second wire-passing channel 52a. During the process of the second arm 52 rotating relative to the first arm 51 around the first axis, the first wire-passing channel 51a and the second wire-passing channel 52a are always connected. The first maximum rotation angle of the second arm 52 relative to the first arm 51 around the first axis is less than or equal to 360°; the rotating assembly 20 A third cable passage 204 is defined in the connecting arm 50 and communicates with the first cavity 201. The transmission cable 40 extends through the third cable passage 204 into the first cavity 201. During the rotation of the first arm 51 relative to the rotating assembly 200, the first cable passage 51a and the third cable passage 204 remain in communication. The first arm 51 is rotatably mounted on the rotating assembly 200 about the second axis. The second maximum rotation angle of the first arm 51 relative to the rotating assembly 200 about the second axis is less than or equal to 360°. As can be understood, housing the battery 61 in the connecting arm 50 makes the pan-tilt assembly 20 compact, prevents damage to the pan-tilt assembly 20 by bulging of the battery 61, and facilitates increasing the capacity of the battery 61. Furthermore, the first maximum rotation angle of the second arm 52 relative to the first arm 51 about the first axis is less than or equal to 360°, preventing multiple rotations of the second arm 52 relative to the first arm 51. This prevents excessive twisting of the transmission cable 40 and avoids damage to the transmission cable 40 caused by excessive twisting. For example, the first maximum rotation angle is less than or equal to 270°, etc. The second maximum rotation angle of the first arm 51 relative to the pan-tilt assembly 20 around the second axis is less than or equal to 360°, thereby preventing the first arm 51 from rotating multiple times relative to the pan-tilt assembly 20, thereby preventing the transmission cable 40 from being excessively twisted, and further preventing the transmission cable 40 from being damaged due to excessive twisting.For example, the second maximum rotation angle is less than or equal to 270°.

[0090] It can be understood that the second arm 52 rotates around the first axis relative to the first arm 51 to change the use angle of the electronic terminal; the first arm 51 rotates around the second axis relative to the pan-tilt assembly 20 to change the use angle of the electronic terminal.

[0091] Specifically, refer to Figure 11-19 The first arm body 51 includes a first arm body 51c and a first rotation limiting portion 51d provided on the first arm body 51c, and the first line-passing channel 51a extends to the first arm body 51c.

In the initial state, the first limiting wall 51d1 is abutted against the third limiting wall 52d1. After the second arm body 52 rotates the first maximum angle relative to the first arm body 51, the second limiting wall 51d2 is abutted against the fourth limiting wall 52d2.

[0092] More specifically, refer to Figure 11-19 The rotating component 200 has a fifth limiting wall 205a and a sixth limiting wall 205b. In the initial state, the first arm 51 is against the fifth limiting wall 205a. After the first arm 51 rotates to the second maximum angle relative to the rotating component 200, the first arm 51 is against the sixth limiting wall 205b.

[0093] In some implementations of the present invention, as shown in Figure 11 , the terminal bracket further includes a control board 62 and a tracking camera 63. The control board 62 is electrically connected to the tracking camera 63, the battery 61, and the transmission cable 40. The tracking camera 63 rotates with the rotating assembly 200. The tracking camera 63 is used to capture images of the tracked object. The control board 62 processes the images from the tracking camera 63 to control the drive assembly 400 to drive the rotating assembly 200, thereby placing the tracked object within the image of the tracking camera 63. The electronic terminal includes a camera lens. When the tracking camera 63 is tracking the tracked object, the camera lens captures the tracked object. The tracking camera 63 and the control board 62 are mounted on the second arm 52. It is understood that the tracking camera 63 is used to enable the electronic terminal to track the tracked object. It should be understood that, in the tracking state, both the tracking camera and the camera lens of the electronic terminal are aimed at the tracked object. The transmission cable 40 transmits signals from the control board 62 to the drive assembly 400, enabling the control board 62 to control the drive assembly 400. During tracking, the tracking camera 63 and the camera lens are located on the same side, allowing the camera lens to capture images of the tracked object. As the rotating assembly 200 rotates, the tracking camera 63 follows the rotation of the rotating assembly 200. During tracking, the rotation speed of the rotating assembly 200 is related to the movement speed of the tracked object. Mounting the tracking camera 63 on the second arm 52 brings it closer to the camera lens of the electronic terminal, making it easier for the camera lens to capture images of the tracked object.

[0094] For example, the tracked object can be a person, an object, etc.

[0095] In some other implementations, the driving component 400 is driven by other means, such as directly driving the driving component 400 by controlling the main board 62 .

[0096] In some implementations of the present invention, referring to Figure 1 、 8The terminal bracket also includes a handle 70, which is rotatably connected to the pan-tilt assembly 20. Specifically, the handle 70 is rotatably connected to the rotating assembly 200 of the pan-tilt assembly 20. More specifically, the handle 70 is rotatably connected to the first shell 210 of the pan-tilt assembly 20. The support member 10, the pan-tilt assembly 20, the connecting arm 50, the supporting member 30 and the electronic terminal are suspension members. When the user holds the handle 70, the suspension member is in a suspended state under the action of its own weight, so that the electronic terminal maintains a stable usage angle; specifically, the handle 70 rotates around the third axis relative to the pan-tilt assembly 20; it can be understood that when the terminal bracket is in the suspended state, the handle 70 can rotate freely relative to the pan-tilt assembly 20. More specifically, the terminal bracket also includes a fifth locking member 83, which passes through the handle 70 and the rotating assembly 200. The fifth locking member 83 can lock the handle 70 to the pan-tilt assembly 20. The fifth locking member 83 can be a threaded member (for example, the fifth locking member 83 includes a fifth screw 83a and a fifth nut 83b. The fifth screw 83a passes through the handle 70 and the rotating assembly 200 and is fastened to the fifth nut 83b. Locking the fifth screw 83a and the fifth nut 83b creates friction resistance between the handle 70 and the pan-tilt assembly 20; when the handle 70 is locked to the pan-tilt assembly 20, the user can hold the handle 70 and use the handle 70 to adjust the use angle of the electronic terminal); when the handle 70 is loosened relative to the pan-tilt assembly 20, the handle 70 can rotate freely relative to the pan-tilt assembly 20. Furthermore, the terminal bracket also includes a remote control 90, which is communicatively connected to the electronic terminal. The handle 70 is provided with a mounting slot 71, and the remote control 90 is embedded in the mounting slot 71.

The connecting arm 50 also includes a connector 53, which is rotatably connected to the second arm body 52. The supporting member 30 is rotatably connected to the connector 53. Rotation of the connector 53 relative to the second arm body 52 can change the use angle of the electronic terminal. Rotation of the supporting member 30 relative to the connector 53 can change the use angle of the electronic terminal. Specifically, rotation of the supporting member 30 relative to the connector 53 can change the width (horizontal, oblique, vertical, etc.) of the electronic terminal. Specifically, the connector 53 is rotatably connected to the second arm body 52 around a fourth axis, and the supporting member 30 is rotatably connected to the connector 53 around a fifth axis; more specifically, the angle between the fourth axis and the first axis is greater than or equal to 75° and less than or equal to 90° (75°, 80°, 85°, 90°, etc.), and the angle between the fifth axis and the fourth axis is greater than or equal to 75° and less than or equal to 90° (75°, 80°, 85°, 90°, etc.).

The first locking member 81 creates friction resistance between the first arm body 51 and the rotating assembly 200, so that the connecting arm 50 can be retained on the pan-tilt assembly 20. The first locking member 81 can be a threaded member (the first locking member 81 includes a first screw 81a and a first nut 81b. The first screw 81a passes through the connecting arm 50 and the pan-tilt assembly 20 and is fastened to the first nut 81b). In other examples, there is a third damping ring between the first arm body 51 and the rotating assembly 200, so that there is friction resistance between the first arm body 51 and the rotating assembly 200, and the third damping ring is made of an elastomeric polymer material, such as rubber, plastic, etc.; in other examples, there is an interference fit between the first arm body 51 and the rotating assembly 200, so that there is friction resistance between the first arm body 51 and the rotating assembly 200; in other examples, the first arm body 51 can be clamped to the rotating assembly 200 at multiple positions, so that the connecting arm 50 is maintained at a certain position on the pan-tilt assembly 20.

The third locking member creates frictional resistance between the first arm 51 and the second arm 52. In other examples, the first arm 51 and the second arm 52 are interference fit, so that frictional resistance exists between the first arm 51 and the second arm 52. In other examples, the second arm 52 can be clamped to the first arm 51 at multiple positions, so that the second arm 52 is retained on the first arm 51 at a certain position.

In other examples, a fourth damping ring is provided between the connector 53 and the second arm 52. The fourth damping ring is made of an elastomeric polymer material, such as rubber or plastic, and provides frictional resistance between the connector 53 and the second arm 52. In other examples, the connector 53 and the second arm 52 are interference-fitted, providing frictional resistance between the connector 53 and the second arm 52. In other examples, the connector 53 can be snap-fitted to the second arm 52 at multiple locations, so that the connector 53 is retained on the second arm 52 at a certain position.

[0101] Understandably, referring to Figure 13, the supporting member 30 can be retained on the connector 53. Specifically, there is a second damping ring 85 between the connector 53 and the supporting member 30. The second damping ring 85 is made of an elastomeric polymer material, such as rubber, plastic, etc., so that there is friction resistance between the connector 53 and the supporting member 30, so that the supporting member 30 can be retained on the connector 53. In other examples, the terminal bracket also includes a fourth locking member, which passes through the supporting member 30 and the connector 53. The fourth locking member creates friction resistance between the supporting member 30 and the connector 53.

In other examples, the supporting member 30 can be clamped to the connector 53 at multiple positions, so that the supporting member 30 can be retained on the connector 53 at a certain position.

[0102] Reference Figure 31 , an example is given to illustrate a usage method of the terminal bracket. When the three legs 11 of the terminal bracket are opened, the terminal bracket can be supported on a supported surface. The telescopic rod of the telescopic support member 10 can adjust the distance between the electronic terminal and the supported surface. The rotating component 200 of the pan-tilt assembly 20 can rotate relative to the fixed component 100 to adjust the use angle of the electronic terminal. The connecting arm 50 can rotate relative to the pan-tilt assembly 20 to adjust the use angle of the electronic terminal. The second arm body 52 can rotate relative to the first arm body 51 to adjust the use angle of the electronic terminal. The connecting head 53 can rotate relative to the second arm body 52 to adjust the use angle of the electronic terminal. The supporting member 30 can rotate relative to the connecting head 53 to change the width of the electronic terminal.

The user holds the support body 13 and the telescopic rod of the telescopic support member 10 can adjust the distance between the electronic terminal and the user. The rotating component 200 of the pan-tilt assembly 20 rotates relative to the fixed component 100 to adjust the use angle of the electronic terminal. The connecting arm 50 rotates relative to the pan-tilt assembly 20 to adjust the use angle of the electronic terminal. The second arm body 52 rotates relative to the first arm body 51 to adjust the use angle of the electronic terminal. The connecting head 53 rotates relative to the second arm body 52 to adjust the use angle of the electronic terminal. The supporting member 30 rotates relative to the connecting head 53 to change the width of the electronic terminal.

[0104] For example, another way to use the terminal bracket is that the user holds the handle 70, and the support member 10, pan-tilt assembly 20, connecting arm 50, supporting member 30 and electronic terminal are suspended under the action of their own weight, and the shaking of the handle 70 around the third axis will not change the use angle of the electronic terminal.
