[0055] The utility model discloses an end support, support subassembly 100, holder subassembly and support component 300, support subassembly 100 for supporting holder subassembly, holder subassembly includes fixed component 500, rotating subassembly 600 and drive subassembly 710, fixed component 500 installs in support subassembly 100, rotating subassembly 600 around first rotation axis 601 rotation installs in fixed component 500, drive subassembly 710 is used for drive rotating subassembly 600 around first rotation axis 601 rotation relative to fixed component 500 to change the use direction of electronic terminal 200, support component 300 around second axis 301 rotation installs in rotating subassembly 600 to adjust the use direction of electronic terminal 200, and support component 300 is used for supporting electronic terminal 200, the included angle of second axis 301 and first rotation axis 601 is less than or equal to 5, and the distance of second axis 301 and first rotation axis 601 is less than or equal to 0.5cm.

[0056] Understandably, because the included angle between second axis 301 and first rotation axis 601 is small and the distance is close, the eccentric distance of support component 300 and electronic terminal 200 relative to first rotation axis 601 changes little in the process that support component 300 rotates around second axis 301 relative to rotating subassembly 600 to make different use directions of electronic terminal 200, so that the end support always maintains a relatively stable use state when support component 300 and electronic terminal 200 rotate around first rotation axis 601 under different use directions of electronic terminal 200 around second axis 301.

[0057] For example, the second axis 301 can intersect, cross, be parallel to, or coaxial with the first rotation axis 601. When the second axis 301 intersects the first rotation axis 601, the second axis 301 and the first rotation axis 601 are non-coplanar. When the second axis 301 intersects the first rotation axis 601, the angle between the second axis 301 and the first rotation axis 601 is less than or equal to 5°, and the distance between the second axis 301 and the first rotation axis 601 is 0. When the second axis 301 crosses the first rotation axis 601, the angle between the second axis 301 and the first rotation axis 601 is less than or equal to 5°, and the distance between the second axis 301 and the first rotation axis 601 is less than or equal to 0.5 cm. When the second axis 301 is parallel to the first rotation axis 601, the angle between the second axis 301 and the first rotation axis 601 is 0, and the distance between the second axis 301 and the first rotation axis 601 is less than or equal to 0.5 cm. When the second axis 301 is coaxial with the first rotation axis 601, the angle between the second axis 301 and the first rotation axis 601 is 0, and the distance between the second axis 301 and the first rotation axis 601 is 0.

[0058] For example, the electronic terminal 200 can be a mobile phone, a tablet, a camera, or the like. It can be understood that the rotation assembly 600 rotates relative to the fixed assembly 500 about the first rotation axis 601, and the use direction of the electronic terminal 200 can be changed. The use direction of the electronic terminal 200 can refer to the use direction of the screen 220 of the electronic terminal 200, and the use direction of the electronic terminal 200 specifically refers to the outward normal direction of the screen 220 of the electronic terminal 200. The use direction of the electronic terminal 200 can also refer to the use direction of the lens 210 of the electronic terminal 200, and specifically, the use direction of the lens 210 specifically refers to the direction along the axis of the lens 210 pointing to the photographed object. A specific use scenario is that the supporting assembly 300 rotates relative to the rotation assembly 600 about the second axis 301, so that the use direction of the screen 220 of the electronic terminal 200 changes from facing the user to facing away from the user (or from facing away from the user to facing away from the user). Another specific use scenario is that the supporting assembly 300 rotates relative to the rotation assembly 600 about the second axis 301, so that the use direction of the lens 210 of the electronic terminal 200 changes from facing the photographed object to facing away from the photographed object (or from facing away from the photographed object to facing away from the photographed object).

[0059] More specifically, the lens 210 of the electronic terminal 200 includes a main lens 210 and a sub lens 210, the main lens 210 and the sub lens 210 are located at opposite sides of the electronic terminal 200 respectively, the sub lens 210 and the screen 220 are located at the same side of the electronic terminal 200, the supporting assembly 300 is rotatable relative to the rotating assembly 600 about the second axis 301, so that the using direction of the sub lens 210 is changed from facing the photographed object to facing the main lens 210 (or the using direction of the main lens 210 is changed from facing the photographed object to facing the sub lens 210. Wherein the photographed object can be the user of the electronic terminal 200 or a third person.

[0060] Specifically, the driving assembly 710 is used for driving the rotating assembly 600 to rotate relative to the fixed assembly 500 about the first rotation axis 601 to change the using direction of the electronic terminal 200, for example, changing the using direction of the electronic terminal 200 to realize that the lens 210 of the electronic terminal 200 follows the photographed object, the photographed object can be a person, an object or the like; for another example, changing the using direction of the electronic terminal 200 to realize that the using direction of the screen 220 of the electronic terminal 200 faces the user.

[0061] It should be understood that the supporting assembly 300 is rotatable about the second axis 301 and is installed on the rotating assembly 600 to adjust the using direction of the electronic terminal 200, for example, the user adjusts the supporting assembly 300 by hand to make the supporting assembly 300 rotatable about the second axis 301 and installed on the rotating assembly 600 to adjust the using direction of the electronic terminal 200.

[0062] In the embodiment of the present application, the included angle between the lines is defined as greater than or equal to 0° and less than or equal to 90°. In the case of intersection of lines (two straight lines intersect at an intersection point), the included angle between the lines is greater than 0° and less than or equal to 90°; in the case of intersection of lines (two straight lines are in different planes but not parallel), the included angle between the lines is greater than 0° and less than or equal to 90°; in the case of parallel or coaxial lines, the included angle between the lines is equal to 0°. In the embodiment of the present application, in the case of intersection or coaxial of lines, the distance between the lines is 0; in the case of intersection or parallel of lines, the distance between the lines is greater than 0.

[0063] Exemplarily, the support assembly 100 has at least one support manner. For example, the support assembly 100 can be supported on a support surface (such as a table top, a ground, etc.), in particular, the support assembly 100 has a support plate, or the support assembly 100 has at least three supporting legs 130, so that the support surface can be a supported plane or a supported curved surface. For another example, the support assembly 100 can be adsorbed on a support surface (such as a table top, a car glass surface, a wall surface, a car console surface, etc.), in particular, the support assembly 100 has a suction cup portion, so that the support assembly 100 can be adsorbed on the support surface. For another example, the support assembly 100 can be magnetically adsorbed on a magnetically adsorbed surface (such as a ferromagnetic surface, etc.), the magnetically adsorbed surface has ferromagnetic or permanent magnetic properties, the support assembly 100 has a magnetic adsorption portion, and the magnetic adsorption portion is made of permanent magnetic material. For another example, the support assembly 100 can be clamped on a clamped object (such as a table top, a railing, a bed head, a chair armrest, etc.), the support assembly 100 has a clamping portion 341, and the clamped object can be a plate-shaped object or a rod-shaped object. For another example, the support assembly 100 can be held by a user, and in the state that the user holds the support assembly 100, the terminal support is a kind of selfie support.

[0064] Referring to Figure 1 , Figure 12 , Figure 22 , Figure 23In one specific implementation of the support assembly 100, the support assembly 100 includes a support rod 110, a support body 120, at least three supporting legs 130, and a locking assembly 140. The support rod 110 is mounted to the support body 120, and is a telescopic rod. A holder assembly is mounted to the support rod 110. The support rod 110 is telescopically adjustable to adjust the distance between the electronic terminal 200 and the support body 120. The supporting legs 130 are rotatably mounted to the support body 120. The supporting legs 130 are openable or foldable relative to the support body 120. In a state where the at least three supporting legs 130 are all open relative to the support body 120, the at least three supporting legs 130 can be supported on a supported surface. In a state where the at least three supporting legs 130 are all folded relative to the support body 120, the support body 120 is convenient for a user to hold. Specifically, the support body 120 is provided with at least three receiving grooves 101, and the supporting legs 130 are foldable into the corresponding receiving grooves 101. The locking assembly 140 is rotatably mounted to the support body 120. The locking assembly 140 has at least three avoiding grooves 102 and at least three abutting walls 103. In a first position relative to the support body 120, the supporting legs 130 are openable or foldable relative to the support body 120. During the process of opening or folding the supporting legs 130 relative to the support body 120, the avoiding grooves 102 avoid the corresponding supporting legs 130. In a state where the supporting legs 130 are open relative to the support body 120, the locking assembly 140 is rotatable to a second position relative to the support body 120. In a state where the supporting legs 130 are open relative to the support body 120, the locking assembly 140 is in the second position relative to the support body 120, and the supporting legs 130 are supported on a supported surface, the supporting legs 130 abut against the corresponding abutting walls 103.

[0065] In another implementation of the support assembly 100, the support assembly 100 includes a support rod 110, a sliding sleeve 150, at least three supporting legs 130, and at least three connecting rods 160. The sliding sleeve 150 is slidably mounted to the support rod 110 along the length direction of the support rod 110. Each supporting leg 130 is rotatably mounted to the sliding sleeve 150. The at least three supporting legs 130 correspond to the at least three connecting rods 160, respectively. One end of each connecting rod 160 is rotatably mounted to the support rod 110, and the other end of each connecting rod 160 is rotatably mounted to the corresponding supporting leg 130. The sliding sleeve 150 is slidable to make the at least three supporting legs 130 foldable or openable relative to the support rod 110. In a state where the at least three supporting legs 130 are open relative to the support rod 110, the at least three supporting legs 130 can be supported on a supported surface. In a state where the at least three supporting legs 130 are folded relative to the support rod 110, the at least three supporting legs 130 are convenient for a user to hold.

[0066] In some implementation manners of the embodiments of the utility model, the length of the support assembly 100 is adjustable or fixed, for example, the support assembly 100 can further have a support rod 110 to support the electronic terminal 200 at a certain height or distance, the fixing assembly 500 is installed on the support rod 110, for example, the support rod 110 is a telescopic rod, and the support rod 110 is in a retracted state when the terminal support is in a storage state; for another example, the support rod 110 is a flexible rod. For another example, the support rod 110 is a rod with a fixed length.

[0067] In some optional implementation manners, the fixing assembly 500 is fixedly installed on the support assembly 100, or the fixing assembly 500 is movably installed on the support assembly 100, for example, the fixing assembly 500 has a plug-in column 510, the support rod 110 of the support assembly 100 has a plug-in hole 104, the plug-in column 510 is plugged into the plug-in hole 104, and the plug-in column 510 is in interference fit with the plug-in hole 104. Preferably, the fixing assembly 500 is installed at the top end of the support assembly 100.

[0068] For example, the holder assembly can be a manual holder or a driven holder, for example, the holder assembly further includes a driving assembly 710, and the driving assembly 710 is used to drive the rotating assembly 600 to rotate relative to the fixing assembly 500 around the first rotation axis 601.

[0069] The support assembly 300 can support the electronic terminal 200 through clamping, adsorption, magnetic attraction or clamping and the like. Specifically, the support assembly 300 includes a support piece 340, the support piece 340 can be directly or indirectly installed on the rotating assembly 600 of the holder assembly, the support piece 340 is a clamp for clamping the electronic terminal 200, the clamp includes a clamp body and two clamping parts 341, the two clamping parts 341 are clamped on opposite two sides of the electronic terminal 200 respectively, and the clamp body can be elastically extended and retracted to adjust the clamping width of the clamp; in some implementation manners, the clamping part 341 can be stored in the clamp body. For another example, the support piece 340 is a suction disc for adsorbing the electronic terminal 200, for example, the suction disc can be adsorbed on the back of the electronic terminal 200. For another example, the support piece 340 is a magnetic attraction piece for magnetically attracting the electronic terminal 200, and the magnetic attraction piece can be an electromagnet or a permanent magnet. For another example, the support piece 340 is a tray for supporting the electronic terminal 200, and the electronic terminal 200 is placed on the tray. For another example, the support piece 340 is a clamping piece for clamping the electronic terminal 200.

[0070] For example only, the driving assembly 710 includes a motor body 711 and an output shaft 712, the output shaft 712 is rotatably mounted on the motor body 711 around the first rotation axis 601, the motor body 711 is fixedly mounted on the rotating assembly 600, the output shaft 712 is fixedly circumferential to the fixed assembly 500 around the first rotation axis 601, and the output shaft 712 rotates relative to the motor body 711 around the first rotation axis 601 to rotate the rotating assembly 600 relative to the fixed assembly 500 around the first rotation axis 601.

[0071] In some implementations, the second axis 301 is coaxial with the first rotation axis 601. It can be understood that, because the second axis 301 is coaxial with the first rotation axis 601, the eccentric distance between the supporting assembly 300 and the electronic terminal 200 relative to the first rotation axis 601 remains unchanged during the rotation of the supporting assembly 300 relative to the rotating assembly 600 around the second axis 301 to change the use direction of the electronic terminal 200, so that the terminal support always remains in a stable use state when the supporting assembly 300 and the electronic terminal 200 rotate around the first rotation axis 601 in different use directions of the electronic terminal 200. In this case, the angle between the second axis 301 and the first rotation axis 601 is 0, and the distance between the second axis 301 and the first rotation axis 601 is 0.

[0072] In some implementations, in the first use state of the terminal support, the holder assembly 300 can rotate relative to the rotating assembly 600 around the second axis 301 to change the use direction of the electronic terminal 200, and the rotating assembly 600 can rotate relative to the fixed assembly 500 around the first rotation axis 601; in the first use state of the terminal support, the shortest distance between the electronic terminal 200 and the first rotation axis 601 is always less than or equal to 2 cm. It can be understood that, in the first use state of the terminal support, the electronic terminal 200 is always close to the first rotation axis 601, so that the terminal support is relatively stable during the rotation of the rotating assembly 600 relative to the fixed assembly 500 around the first rotation axis 601.

[0073] The shortest distance between the electronic terminal 200 and the first rotation axis 601 is defined as the minimum distance from any point of the electronic terminal 200 to the first rotation axis 601, wherein the electronic terminal 200 includes a terminal body and an accessory, the terminal body can realize the basic functions of the electronic terminal 200, and the accessory can be a protective shell, an auxiliary camera, an auxiliary fill light, etc.

Understandably, in the first use state of the terminal support, the first projection and the second projection always intersect, and the electronic terminal 200 is always close to the first rotation axis 601, so that the terminal support is relatively stable during the rotation of the rotating assembly 600 relative to the fixed assembly 500 about the first rotation axis 601.

[0075] In some embodiments, the gimbal assembly further includes a bearing assembly 720, the bearing assembly 720 is mounted to the fixed assembly 500, the bearing assembly 720 is mounted to the rotating assembly 600, and the bearing assembly 720 enables the rotating assembly 600 to rotate about the first rotation axis 601 relative to the fixed assembly 500; the rotating assembly 600 includes a first housing 610, the first housing 610 encloses a first cavity 602, and the bearing assembly 720 is accommodated in the first cavity 602; the first housing 610 has a first sub-projection on the first plane, and in the first use state of the terminal support, the first sub-projection and the second projection always intersect.

Understandably, in the first use state of the terminal support, the first rotation axis 601 and the electronic terminal 200 are located on the same side of the first arm body 310, so that the terminal support is more stable during use. For example, the first arm body 310 is directly or indirectly mounted to the rotating assembly 600.

[0077] In some implementations, the supporting assembly 300 further comprises a supporting member 340 and a second arm body 320 connected to the first arm body 310, the supporting member 340 is rotatable relative to the first arm body 310 to enable the electronic terminal 200 to be on different sides of the first arm body 310, the second arm body 320 is rotatable relative to the gimbal assembly to enable the first arm body 310 to be folded on the gimbal assembly, in the first use state of the terminal support, the supporting member 340 and the second arm body 320 are on the same side of the first arm body 310, in the storage state of the terminal support, the first arm body 310 is folded on the gimbal assembly, the gimbal assembly and the electronic terminal 200 are respectively on opposite sides of the first arm body 310, and the gimbal assembly and the second arm body 320 are on the same side of the first arm body 310. It can be understood that, in the first use state of the terminal support, the supporting member 340 and the second arm body 320 are on the same side of the first arm body 310, so that the terminal support is more stable in this use state.

[0078] It can be understood that the supporting member 340 is rotatable relative to the first arm body 310 to enable the electronic terminal 200 to be on different sides of the first arm body 310, which is convenient for the terminal support in the first use state on the one hand, and is convenient for the first arm body 310 to be folded on the gimbal assembly in the storage state of the terminal support, so that the terminal support is more compact in the storage state.

[0079] For example, the supporting member 340 is directly or indirectly mounted on the first arm body 310, for example, the supporting member 340 is indirectly mounted on the first arm body 310 through an intermediate member. For example, in the first use state of the terminal support, the first straight line is parallel to the first rotation axis 601. Specifically, the supporting assembly 300 further comprises a third arm body 330 rotatably connected to the first arm body 310, the supporting member 340 is directly or indirectly mounted on the third arm body 330, and the third arm body 330 is rotatable relative to the first arm body 310 to enable the supporting member 340 to be rotatable relative to the first arm body 310, and in turn enable the electronic terminal 200 to be on different sides of the first arm body 310.

[0080] More specifically, the supporting assembly 300 further comprises a connecting head 360, the third arm body 330 is mounted on the connecting head 360, and the supporting member 340 is mounted on the connecting head 360. Specifically, the supporting member 340 is rotatably mounted on the connecting head 360, the supporting member 340 is rotatable relative to the connecting head 360 to adjust the width direction (e.g. horizontal width, vertical width, oblique width, etc.) of the electronic terminal 200, the supporting member 340 is retainable on the connecting head 360, and the supporting member 340 is rotatably mounted on the connecting head 360 about a third axis. The connecting head 360 is rotatably mounted on the third arm body 330, the connecting head 360 is rotatable relative to the third arm body 330 to adjust the use direction of the electronic terminal 200, the connecting head 360 is retainable on the third arm body 330, the connecting head 360 is rotatably mounted on the third arm body 330 about a fourth axis, and the angle between the third axis and the fourth axis is greater than or equal to 85° and less than or equal to 90° (e.g. 90°). The third arm body 330 is rotatably mounted on the first arm body 310 about a fifth axis, the angle between the fifth axis and the fourth axis is greater than or equal to 85° and less than or equal to 90° (e.g. 90°), the third arm body 330 is retainable on the first wall body, and more specifically, the angle between the fifth axis and the first straight line is greater than or equal to 0° and less than or equal to 5° (e.g. 0°). The second arm body 320 is rotatably mounted on the mounting member 350 about a sixth axis, the angle between the sixth axis and the fifth axis is greater than or equal to 85° and less than or equal to 90° (e.g. 90°), the angle between the sixth axis and the first rotation axis 601 is greater than or equal to 85° and less than or equal to 90° (e.g. 90°), and the second arm body 320 is retainable on the mounting member 350.

[0081] For example, the second arm body 320 is rotatable relative to the holder assembly, and the second arm body 320 is directly or indirectly rotatably connected to the holder assembly; specifically, the supporting assembly 300 further comprises a mounting member 350, and the second arm body 320 is rotatably connected to the mounting member 350, and the mounting member 350 is rotatably mounted on the rotation assembly 600 about the second axis 301.

[0082] The holder assembly and the electronic terminal 200 are respectively on opposite sides of the first arm body 310, which can mean that the holder assembly directly faces the electronic terminal 200, or that the holder assembly is obliquely opposite to the electronic terminal 200.

[0083] In some implementations, the supporting assembly 300 has at least one first clamping portion 302, the rotation assembly 600 has at least one second clamping portion 611, and the first clamping portion 302 cooperates with the corresponding second clamping portion 611 to retain the supporting assembly 300 on the rotation assembly 600. It should be understood that the supporting assembly 300 is retained on the rotation assembly 600, so that the terminal support has a relatively stable use state during rotation of the rotation assembly 600, the supporting assembly 300 and the electronic terminal 200 as a whole about the first rotation axis 601.

[0084] For example, the number of the first clamping parts 302 is 1, the number of the second clamping parts 611 is 1, and the 1 first clamping part 302 is clamped in the corresponding 1 second clamping part 611, so that the support assembly 300 is kept in 1 holding position relative to the rotating assembly 600.

[0085] For example, the number of the first clamping parts 302 is 1, the number of the second clamping parts 611 is at least 2, and the 1 first clamping part 302 is clamped in any 1 second clamping part 611, so that the support assembly 300 is kept in at least 2 holding positions relative to the rotating assembly 600.

[0086] For example, the number of the first clamping parts 302 is 1, the number of the second clamping parts 611 is at least 2, and the 1 first clamping part 302 is clamped in any 1 second clamping part 611, so that the support assembly 300 is kept in at least 2 holding positions relative to the rotating assembly 600.

[0087] For example, the number of the first clamping parts 302 is 2, the number of the second clamping parts 611 is 2, the 2 first clamping parts 302 are arranged uniformly around the second axis 301, the 2 second clamping parts 611 are arranged uniformly around the second axis 301, and the 2 first clamping parts 302 are clamped in the corresponding 2 second clamping parts 611; different clamping combinations make the support assembly 300 kept in 2 holding positions relative to the rotating assembly 600.

[0088] For example, the number of the first clamping parts 302 is 2, the number of the second clamping parts 611 is 2, the 2 first clamping parts 302 are arranged non-uniformly around the second axis 301, the 2 second clamping parts 611 are arranged non-uniformly around the second axis 301, and the 2 first clamping parts 302 are clamped in the corresponding 2 second clamping parts 611, so that the support assembly 300 is kept in 1 holding position relative to the rotating assembly 600.

[0089] For example, the number of the first clamping parts 302 is M, the number of the second clamping parts 611 is N, N is greater than or equal to M, the N second clamping parts 611 are arranged uniformly around the second axis 301, and the M first clamping parts 302 are clamped in the corresponding M second clamping parts 611; different clamping combinations make the support assembly 300 kept in N holding positions relative to the rotating assembly 600.

[0090] For example, the number of the second clamping parts 611 is M, the number of the first clamping parts 302 is N, N is greater than or equal to M, the N first clamping parts 302 are arranged uniformly about the second axis 301, and the M second clamping parts 611 are clamped in the corresponding M first clamping parts 302; different clamping combinations allow the support assembly 300 to be kept in N holding positions relative to the rotating assembly 600.

[0091] It can be understood that, in the state that the support assembly 300 is kept in the rotating assembly 600, the rotating assembly 600 applies a holding torque to the support assembly 300, and in the process that the rotating assembly 600, the support assembly 300 and the electronic terminal 200 rotate as a whole about the first rotation axis 601, the support assembly 300 does not swing about the second axis 301.

[0092] In some implementations, the support assembly 300 has a first mounting part 350a, the first clamping part 302 is a clamping groove provided on the first mounting part 350a, the rotating assembly 600 has a second mounting part 610a, the first mounting part 350a is rotatably mounted on the second mounting part 610a about the first rotation axis 601, the second mounting part 610a is provided with a deformation groove 603 corresponding to the second clamping part 611, the second clamping part 611 includes a first cantilever 611a and a first clamping protrusion 611b, the first clamping protrusion 611b is provided at one end of the first cantilever 611a, the first cantilever 611a is connected to the second mounting part 610a, the first cantilever 611a is located in the deformation groove 603, and the first cantilever 611a is configured to apply an elastic force to the first clamping protrusion 611b so that the first clamping protrusion 611b of the second clamping part 611 is fitted in the clamping groove of the corresponding first clamping part 302; in the process that the first clamping part 302 cooperates with or separates from the corresponding second clamping part 611, the deformation groove 603 serves as a deformation space for the first cantilever 611a of the corresponding second clamping part 611. It can be understood that the first cantilever 611a applies an elastic force to the first clamping protrusion 611b, so that the support assembly 300 is more stably kept in the rotating assembly 600, and the terminal support has a more stable use state in the process that the rotating assembly 600, the support assembly 300 and the electronic terminal 200 rotate as a whole about the first rotation axis 601.

[0093] It can be understood that the first cantilever 611a deforms in the corresponding deformation groove 603, so that the first cantilever 611a and the second clamping part 611 do not interfere with the corresponding first clamping part 302 in the process that the first clamping part 302 cooperates with or separates from the corresponding second clamping part 611, and the first cantilever and the second clamping part 611 do not hinder the rotation of the support assembly 300 about the second axis 301.

[0094] It should be understood that the torque of rotating the supporting assembly 300 is greater than the holding torque of the supporting assembly 300, so that the first clamping portion 302 is disengaged from the second clamping portion 611. The torque of rotating the supporting assembly 300 can be derived from the torque applied to the supporting assembly 300 by the user's hand.

[0095] In other embodiments, the second clamping portion 611 is a clamping groove provided on the first mounting portion 350a, and the first clamping portion 302 includes a first cantilever 611a and a first clamping protrusion 611b.

It should be understood that the elastic member 611d enables the positioning bead 611e to more closely engage the clamping groove, so that the supporting assembly 300 is more stably retained in the rotating assembly 600, and so that the terminal support has a more stable use state during the rotation of the rotating assembly 600, the supporting assembly 300, and the electronic terminal 200 as a whole about the first rotating axis 601.

[0098] It can be understood that the elastic member 611d is elastically deformed during the cooperation or disengagement of the first clamping part 302 and the second clamping part 611, and the positioning bead 611e rolls in the accommodation groove 604, so that the positioning bead 611e does not interfere with the corresponding first clamping part 302 during the cooperation or disengagement of the first clamping part 302 and the corresponding second clamping part 611, so that the positioning bead 611e does not hinder the rotation of the supporting assembly 300 around the second axis 301. It should be understood that the torque for rotating the supporting assembly 300 is greater than the holding torque of the supporting assembly 300, so that the first clamping part 302 and the second clamping part 611 are disengaged, and the torque for rotating the supporting assembly 300 can be derived from the torque exerted on the supporting assembly 300 by the user's hand.

[0099] It can be understood that the mounting column 611c is detachably mounted on the second mounting part 610a, which facilitates the manufacturing of the second clamping part 611.

[0100] In some implementations, the second mounting part 610a is provided with a fitting groove 605 matched with the mounting column 611c, and the mounting column 611c is embedded in the accommodation groove 604; the mounting column 611c is provided with a first opening 604a, the first opening 604a is in communication with the accommodation groove 604, the positioning bead 611e protrudes from the mounting column 611c through the first opening 604a, and the first opening 604a is in the shape of a neck to prevent the positioning bead 611e from coming out of the accommodation groove 604.

[0106] In some embodiments, the number of the first clamping portions 302 is 2N, the number of the second clamping portions 611 is M, the 2N first clamping portions 302 are arranged uniformly around the second axis 301 and are centrally symmetric about the second axis 301, 2N≥M, and the M first clamping portions 302 are clamped in the corresponding M second clamping portions 611. The 2N clamping combinations of the 2N first clamping portions 302 and the M second clamping portions 611 allow the support assembly 300 to be kept in 2N holding positions relative to the rotating assembly 600. Alternatively, the number of the second clamping portions 611 is 2N, the number of the first clamping portions 302 is M, the 2N second clamping portions 611 are arranged uniformly around the second axis 301 and are centrally symmetric about the second axis 301, 2N≥M, and the M first clamping portions 302 are clamped in the corresponding M second clamping portions 611. The 2N clamping combinations of the 2N second clamping portions 611 and the M first clamping portions 302 allow the support assembly 300 to be kept in 2N holding positions relative to the rotating assembly 600. It can be understood that the number of the first clamping portions 302 is even, the 2N first clamping portions 302 are arranged uniformly around the second axis 301 and are centrally symmetric about the second axis 301, and in the state that the M first clamping portions 302 are clamped in the corresponding M second clamping portions 611 (i.e., the support assembly 300 is kept in one of the holding positions relative to the rotating assembly 600), the M first clamping portions 302 are still clamped in the corresponding M second clamping portions 611 (so that the support assembly 300 is kept in another one of the holding positions relative to the rotating assembly 600) after the support assembly 300 is rotated by 180° about the second axis 301.

[0107] It can be understood that the number of the second clamping portions 611 is even, 2N second clamping portions 611 are arranged in a ring around the second axis 301 uniformly and are centrally symmetric, and in the state that the M first clamping portions 302 are clamped in the corresponding M second clamping portions 611 (i.e., the support assembly 300 is kept in one of the holding positions relative to the rotating assembly 600), the M first clamping portions 302 are still clamped in the corresponding M second clamping portions 611 after the support assembly 300 rotates 180° around the second axis 301 (so that the support assembly 300 is kept in another holding position relative to the rotating assembly 600).

[0108] It can be understood that the central symmetry is that the figure of an object is coincident with the initial figure after the figure rotates 180° around an axis. It can be understood that the support assembly 300 is kept in one of the holding positions relative to the rotating assembly 600, and after the support assembly 300 rotates 180° around the second axis 301, the support assembly 300 is kept in another holding position relative to the rotating assembly 600. The advantage of such an arrangement is to facilitate the use of the terminal support; for example, rotating the support assembly 300 by 180° so that the use direction of the electronic terminal 200 is reversed; more specifically, rotating the support assembly 300 by 180° so that the use direction of the lens 210 of the electronic terminal 200 is changed from facing the photographed object to being away from the photographed object, the use direction of the lens 210 of the electronic terminal 200 is changed from being away from the photographed object to facing the photographed object, the sub-lens 210 is changed from facing the photographed object to facing the photographed object, the main lens 210 is changed from facing the photographed object to facing the photographed object, the screen 220 is changed from facing the user to being away from the user, the screen 220 is changed from being away from the user to facing the user, the use direction of the electronic terminal 200 is changed from facing forward to facing backward, the use direction of the electronic terminal 200 is changed from facing backward to facing forward, the use direction of the electronic terminal 200 is changed from facing left to facing right, the use direction of the electronic terminal 200 is changed from facing right to facing left, the use direction of the electronic terminal 200 is changed from facing upward to facing downward, and the use direction of the electronic terminal 200 is changed from facing downward to facing upward. All of the above facilitates the use of the terminal support.

[0109] Specifically, the number of the first clamping portions 302 is 2, the number of the second clamping portions 611 is 1 or 2, 2 first clamping portions 302 are arranged in a ring around the second axis 301 uniformly and are centrally symmetric, and the support assembly 300 can be kept in two holding positions; or the number of the second clamping portions 611 is 2, the number of the first clamping portions 302 is 1 or 2, 2 second clamping portions 611 are arranged in a ring around the second axis 301 uniformly and are centrally symmetric, and the support assembly 300 can be kept in two holding positions.

[0110] Specifically, the number of the first clamping parts 302 is 4, the number of the second clamping parts 611 is 1, 2, 3 or 4, the 4 first clamping parts 302 are arranged evenly around the second axis 301 and are centrally symmetric, and the support assembly 300 can be kept in 4 holding positions; or, the number of the second clamping parts 611 is 4, the number of the first clamping parts 302 is 1, 2, 3 or 4, the 4 second clamping parts 611 are arranged evenly around the second axis 301 and are centrally symmetric, and the support assembly 300 can be kept in 4 holding positions.

[0111] In some implementations, in the first use state of the terminal support, the holder assembly 300 can be rotated relative to the rotating assembly 600 around the second axis 301 so that the electronic terminal 200 is in different use directions, and the rotating assembly 600 can be rotated relative to the fixed assembly 500 around the first rotation axis 601.

[0112] In some implementations, the terminal support further comprises a handle 900 rotatably connected to the hanging assembly, in a state that a user holds the handle 900, the hanging assembly is in a hanging state under its own weight, so that the electronic terminal 200 keeps a stable use direction, the hanging assembly comprises the support assembly 100, the holder assembly 300 and the electronic terminal 200, the handle 900 is rotatably connected to the rotating assembly 600 of the holder assembly; in a state that the support assembly 100 is in the support state, the user holding the handle 900 can make the rotating assembly 600 rotate relative to the fixed assembly 500 about the first rotation axis 601; the terminal support further comprises a power supply 810, a control mainboard 820 and a follow-up camera 830, the power supply 810 and the control mainboard 820 are electrically connected, the control mainboard 820 is electrically connected with the driving assembly 710, the control mainboard 820 is electrically connected with the follow-up camera 830, the power supply 810 is installed on the handle 900, the control mainboard 820 is installed on the handle 900, and the follow-up camera 830 is installed on the handle 900; the follow-up camera 830 rotates with the rotating assembly 600, the follow-up camera 830 is used for shooting a tracked object, the control mainboard 820 is used for processing a picture of the follow-up camera 830 to control the driving assembly 710 to drive the rotating assembly 600, so that the tracked object is in the picture of the follow-up camera 830; in a process that the follow-up camera 830 follows the tracked object, the lens 210 of the electronic terminal 200 shoots the tracked object. It should be understood that in a process that the rotating assembly 600 rotates about the first rotation axis 601, the follow-up camera 830 and the electronic terminal 200 all rotate about the first rotation axis 601, so that the follow-up camera 830 follows the tracked object, and so that the lens 210 of the electronic terminal 200 follows the tracked object. For example, in the following process, the follow-up camera 830 and the lens 210 of the electronic terminal 200 are located on the same side, so as to shoot the tracked object. When the terminal support is in the following state, the rotating speed of the rotating assembly 600 is related to the moving speed of the tracked object.

[0113] For example, the tracked object can be a person, an animal or an object.

[0114] It can be understood that in a state that a user holds the handle 900, the hanging assembly is in a hanging state under its own weight, and the handle 900 rotatably connected to the hanging assembly plays a role of a stabilizer. For example, the handle 900 has one or two degrees of rotational freedom relative to the hanging assembly. Specifically, the handle 900 is rotatably connected to the hanging assembly about a seventh axis, and the angle between the seventh axis and the first rotation axis 601 is greater than or equal to 85° and less than or equal to 90° (for example, 90°). In other implementations, the handle 900 is rotatably connected to the support assembly 100, the fixed assembly 500 or the holder assembly 300.

[0115] For example, in the state that the support assembly 100 is supported on the support surface (or in the state that the user holds the support assembly 100 by hand), the user holds the handle 900 to make a movement around the first rotation axis 601, so that the rotation assembly 600 rotates relative to the fixed assembly 500 around the first rotation axis 601, thereby the use direction of the electronic terminal 200 can be manually controlled.

During the rotation of the handle 900 relative to the gimbal assembly, the first wire passage 902 and the second wire passage 607 are always communicated, which facilitates the extension of the transmission cable 840 to the first cavity 602 through the first wire passage 902 and the second wire passage 607. It should be understood that, during the rotation of the handle 900 relative to the gimbal assembly, the transmission cable 840 can be attached to the cavity wall of the first wire passage 902 and the second wire passage 607, the first wire passage 902 or the second wire passage 607 can cause the transmission cable 840 to adaptively deform, and the first wire passage 902 or the second wire passage 607 will not destructively extrude the transmission cable 840. It can be understood that the transmission cable 840 extends in the first wire passage 902 and the second wire passage 607, so that the structure of the terminal support is more compact and occupies a smaller volume. Specifically, when the terminal support is in the storage state, the handle 900 is folded on the gimbal assembly, and the handle 900 and the second arm body 320 are located on opposite sides of the gimbal assembly, respectively.

[0117] For example, the transmission cable 840 is used for transmitting the power of the power supply 810, or the transmission cable 840 is used for transmitting the signal of the control mainboard 820.

[0118] For example, the remote controller 850 is used for controlling the electronic terminal 200, for example, the remote controller 850 controls the electronic terminal 200 to take a photo; the remote controller 850 is connected with the electronic terminal 200 through Bluetooth.
