[0004] The multi-leg support in the prior art generally comprises a supporting rod assembly, a sliding sleeve assembly, at least three supporting leg assemblies, and at least three connecting rods. The at least three connecting rods are respectively corresponding to the at least three supporting leg assemblies. The sliding sleeve assembly is slidingly installed on the supporting rod assembly along the length direction of the supporting rod assembly. One end of the supporting leg assembly is rotationally connected to the sliding sleeve, and the other end can be supported on a supporting surface. One end of the connecting rod is rotationally connected to the supporting rod assembly, and the other end is rotationally connected to the supporting rod assembly. The sliding of the sliding sleeve assembly along the length direction of the supporting rod assembly can adjust the opening degree of the supporting leg assembly relative to the supporting rod assembly.

Since the connecting rod and the support leg assembly are movably connected, when the support leg assembly is folded relative to the support rod assembly, the support leg assembly is easy to open relative to the support rod assembly due to the weight or other factors, thereby being inconvenient for the storage of the multi-leg support. Therefore, the multi-leg support is provided to solve the above problems.

[0117] In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the following will be combined with the accompanying drawings for the embodiments of the present application to make a clear and complete description of the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. The components of the embodiments of the present application described and shown in the accompanying drawings can be arranged and designed in various different configurations.

[0118] Therefore, the following detailed description of the embodiments of the present application provided in the accompanying drawings is not intended to limit the scope of the claimed present application, but only represents selected embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application without creative labor are within the scope of protection of the present application.

[0119] Referring to FIGS. 1-40, the embodiments of the present application provide a multi-leg support for supporting an electronic terminal, comprising a support rod assembly 100, a sliding sleeve assembly 200, at least three support leg assemblies 300, and at least three connecting rods 400; the sliding sleeve assembly 200 is slidingly sleeved on the support rod assembly 100; at least three support leg assemblies 300 are respectively rotationally connected to the sliding sleeve assembly 200; at least three connecting rods 400 correspond to the at least three support leg assemblies 300 respectively, and the at least three connecting rods 400 are respectively rotationally connected to the support rod assembly 100 and the corresponding support leg assemblies 300, and each connecting rod 400 is between the support rod assembly 100 and the corresponding support leg assembly 300; wherein the sliding sleeve assembly 200 slides along the extension direction of the support rod assembly 100 to adjust the unfolding degree of the at least three support leg assemblies 300 relative to the support rod assembly 100; when the at least three support leg assemblies 300 are unfolded to the maximum unfolding state relative to the sliding sleeve assembly 200, the sliding sleeve assembly 200 abuts against the support rod assembly 100.

[0120] Through the abutment of the sliding sleeve assembly 200 and the support rod assembly 100, the sliding stroke of the sliding sleeve assembly 200 relative to the support rod assembly 100 is limited, and then the opening degree of the support leg assembly 300 relative to the support rod assembly 100 is limited, thereby avoiding the excessive unfolding of the support leg assembly 300 to cause the deformation of the connecting rod 400 and the support leg assembly 300, and thus the service life of the multi-leg support is improved.

[0121] For example only, the electronic terminal can be a mobile phone, a tablet computer, a camera, etc.

[0122] For example only, the support pole assembly 100 is telescopic in its length direction, or the support pole assembly 100 is fixed in length; for example, the support pole assembly 100 comprises a plurality of telescopic sections, the plurality of telescopic sections comprising a first telescopic section 111, and the sliding sleeve assembly 200 is sleeved on the first telescopic section 111.

[0123] For example only, the number of the support leg assemblies 300 can be 3, 4, etc., and the number of the connecting rods 400 can be 3, 4, etc., and the number of the connecting rods 400 is the same as the number of the support leg assemblies 300.

[0124] It can be understood that the sliding sleeve assembly 200, the support pole assembly 100, the support leg assembly 300 and the corresponding connecting rod 400 constitute a planar four-bar linkage mechanism, and specifically, the planar four-bar linkage mechanism can be a crank slider mechanism, a rocker slider mechanism, etc.

[0125] For example only, the support leg assembly 300 can be folded into the support pole assembly 100, and after the support leg assembly 300 is folded into the support pole assembly 100, the connecting rod 400 is located between the support pole assembly 100 and the corresponding support leg assembly 300. In the state that the support leg assembly 300 is folded into the support pole assembly 100, at least three support leg assemblies can be held by the user.

[0126] It can be understood that the extension direction of the support pole assembly 100 is the length direction of the support pole assembly 100.

[0127] Referring to FIG. 17, and FIGS. 19-27, the sliding sleeve assembly 200 comprises a main sleeve 230, a first sleeve 210 and a second sleeve 220, the main sleeve 230 is provided with a mounting cavity 201, the first sleeve 210 and the second sleeve 220 are sleeved in the mounting cavity 201, and the first sleeve 210, the second sleeve 220 and the main sleeve 230 are fixed with each other; the first sleeve 210 is sleeved on the support rod assembly 100, and the second sleeve 220 is sleeved on the support rod assembly 100; when the three support leg assemblies 300 are unfolded to the maximum unfolded state relative to the sliding sleeve assembly 200, the second sleeve 220 abuts against the support rod assembly 100. The first sleeve 210 and the second sleeve 220 of the sliding sleeve assembly 200 are both sleeved on the support rod assembly 100, so that the sliding sleeve assembly 200 shakes less when sliding relative to the support rod assembly 100, and the sliding sleeve assembly 200 shakes less relative to the support rod assembly 100 when the multi-leg support is in the supporting state, so that the multi-leg support is more stable. The sliding sleeve assembly 200 is arranged in the form of the main sleeve 230, the first sleeve 210 and the second sleeve 220, which facilitates the manufacturing and installation of the sliding sleeve assembly 200; the first sleeve 210 and the second sleeve 220 are both sleeved in the main sleeve 230, so that the sliding sleeve assembly 200 is compact in structure and small in occupied volume. The first sleeve 210, the second sleeve 220 and the main sleeve 230 are fixed with each other, so that the overall structural strength of the sliding sleeve assembly 200 is better, and the use experience is better.

[0128] For example, the first sleeve 210, the second sleeve 220 and the main sleeve 230 are in direct or indirect contact with each other.

[0129] Referring to FIG. 17, and FIGS. 19-27, the sliding sleeve assembly 200 further comprises at least two first fasteners 240, the first fasteners 240 are fastened and connected through the main sleeve 230, the first sleeve 210 and the second sleeve 220 to fix the first sleeve 210, the second sleeve 220 and the main sleeve 230 with each other.

[0130] Understandably, the first fasteners 240 are fastened and connected through the main sleeve 230, the first sleeve 210 and the second sleeve 220, so that the structure of the sliding sleeve assembly 200 is simple and convenient to assemble; the at least two first fasteners 240 can also limit the circumferential rotation between the first sleeve 210, the second sleeve 220 and the main sleeve 230, so that the overall structural strength of the sliding sleeve assembly 200 is better.

[0131] For example, the first sleeve 210 is in close contact with the second sleeve 220, and the main sleeve 230 is in close contact with the second sleeve 220, so that the first sleeve 210, the second sleeve 220, and the main sleeve 230 are fixed between each other.

[0132] For example, the number of the first fasteners 240 is 2, and the two first fasteners 240 are respectively located on opposite sides of the sliding sleeve assembly 200.

[0133] For example, the first fasteners 240 can be threaded fasteners, riveted fasteners, or the like.

[0134] Referring to FIGS. 17 and 19-27, the first sleeve 210 includes a first sleeve 211 and at least two connecting columns 212 protruding from the outer wall of the first sleeve 211, the first sleeve 211 being sleeved on the support rod assembly 100, and the at least two connecting columns 212 corresponding to the at least two first fasteners 240, respectively; the second sleeve 220 includes a second sleeve 221 and at least two connecting ears 222 protruding from the outer wall of the second sleeve 221, the at least two connecting ears 222 corresponding to the at least two first fasteners 240, respectively, and the main sleeve 230 includes a main sleeve 231 and at least two connecting protrusions 232 protruding from the inner wall of the main sleeve 231, the connecting columns 212 and the connecting ears 222 being located in the mounting cavity 201, the connecting ears 222 being located between the connecting columns 212 and the connecting protrusions 232, and the at least two connecting protrusions 232 corresponding to the at least two first fasteners 240, respectively; the first fasteners 240 are fastened through the corresponding connecting protrusions 232, the corresponding connecting ears 222, and the corresponding connecting columns 212, the connecting protrusions 232 being in close contact with the corresponding connecting ears 222, and the connecting ears 222 being in close contact with the corresponding connecting columns 212.

[0135] It can be understood that the connecting columns 212 and the connecting ears 222 are located in the mounting cavity 201 surrounded by the main sleeve 231, so that the structure of the sliding sleeve assembly 200 is compact, and the connecting columns 212 and the connecting ears 222 are not easily damaged during use of the multi-leg support.

[0136] It can be understood that the connecting columns 212, the connecting ears 222, and the connecting protrusions 232 facilitate the first fasteners 240 to pass through.

[0137] Referring to FIG. 17, and FIGS. 19-27, the first fastener 240 includes a first head 241 and a first rod 242 connected to the first head 241, the first head 241 of the first fastener 240 is in close contact with the corresponding connecting protrusion 232, the first rod 242 of the first fastener 240 is screwed through the corresponding connecting protrusion 232, the corresponding connecting lug 222 and the connecting column 212; the first head 241 of the first fastener 240 protrudes from the bottom surface of the connecting protrusion 232, or alternatively, the connecting protrusion 232 is provided with a receiving hole 202 that is communicated to the bottom surface of the connecting protrusion 232, and the first head 241 of the first fastener 240 is received in the receiving hole 202.

[0138] It can be understood that the first head 241 of the first fastener 240 protrudes from the bottom surface of the connecting protrusion 232 or is received in the receiving hole 202, so that the user is not easy to touch the first head 241 of the first fastener 240 during use of the sliding sleeve assembly, thereby avoiding injury to the user's hand; and the first head 241 is hidden in the bottom surface of the connecting protrusion 232 or the receiving hole 202, and the multi-leg support is more aesthetically pleasing in structure

[0139] It can be understood that "bottom", "top" should be understood according to the common use state of the multi-leg support, and the common use state of the multi-leg support is that the multi-leg support is supported on a support plane, the bottom end of a component refers to the end close to the support plane, the top end of a component refers to the end away from the support plane, the bottom surface of a component refers to the surface close to the support plane, and the top surface of a component refers to the surface away from the support plane.

[0140] It can be understood that the first head 241 of the first fastener 240 is in close contact with the corresponding connecting protrusion 232, and the first rod 242 of the first fastener 240 is screwed through the corresponding connecting protrusion 232, the corresponding connecting lug 222 and the connecting column 212, so that the main sleeve 230, the first sleeve 210 and the second sleeve 220 are fixed between each other.

[0142] It can be understood that the first grooves 205 respectively cooperate with the first alignment part 222a and the second alignment part 212a to align the second connecting hole 203b with the corresponding third connecting hole 203c and to align the first connecting hole 203a with the corresponding second connecting hole 203b, which facilitates the installation of the first fastener 240 and the assembly of the sliding sleeve assembly 200.

[0143] In addition, the first grooves 205 simultaneously realize the alignment of the first sleeve 210 and the second sleeve 220, so that the structure of the sliding sleeve assembly 200 is simple and the manufacturing of the sliding sleeve assembly 200 is facilitated. In addition, the first grooves 205 respectively cooperate with the first alignment part 222a and the second alignment part 212a, which can reduce the shaking of the first sleeve 210 relative to the main sleeve 230 and reduce the shaking of the second sleeve 220 relative to the main sleeve 230, so that the overall structural strength of the sliding sleeve assembly 200 is better.

[0144] For example, the first recess 205 is a stretching slot, the first recess 205 extends along the mounting direction of the first set 210 (the first recess 205 extends along the mounting direction of the second set 220), during the process that the second set 220 is mounted into the second mounting position of the mounting cavity 201 through the first opening 204a, the first alignment part 222a slides along the first recess 205, during the process that the first set 210 is mounted into the first mounting position of the mounting cavity 201 through the first opening 204a, the second alignment part 212a slides along the first recess 205.

[0197] For example, the mounting member 120 comprises a first mounting sub-member 120a and a second mounting sub-member 120b, the second mounting sub-member 120b is mounted on the first mounting sub-member 120a, the first mounting sub-member 120a comprises a mounting column 121, the first mounting sub-member 120a further comprises a part of the mounting protrusion 122, the second mounting sub-member 120b comprises a part of the mounting protrusion 122, the second mounting sub-member 120b is mounted on the first mounting sub-member 120a to form the mounting protrusion 122. In the state that the sliding sleeve assembly 200 is in contact with the mounting member 120, the sliding sleeve assembly 200 is in contact with the first mounting sub-member 120a. Specifically, the second mounting sub-member 120b is mounted on the second mounting sub-member 120b by the third fastener 120c, which can be a threaded fastener, a rivet, etc.; the third rotating part 103 is a hole, and the first mounting sub-member 120a and the second mounting sub-member 120b combine to form the third rotating part 103; the advantage of such an arrangement is that the connecting rod 400 can be conveniently mounted on the support rod assembly 100 for rotation. For example, one way to mount the connecting rod 400 is to place the connecting rod 400 between the first mounting sub-member 120a and the second mounting sub-member 120b, and then mount the second mounting sub-member 120b on the first mounting sub-member 120a by the third fastener 120c.

[0198] Referring to FIGS. 17, 24, 25, 28-30, etc., the multi-leg support further comprises a locking structure 500, the locking structure 500 comprises a locking ring 510 and a locking sleeve 520, the locking ring 510 is sleeved on the support rod assembly 100, the locking sleeve 520 is sleeved on the support rod assembly 100, the locking sleeve 520 is threadedly connected with the sliding sleeve assembly 200, the locking ring 510 has a first taper surface 501, the locking sleeve 520 has a second taper surface 502, the locking ring 510 has a third taper surface 503, and the sliding sleeve assembly 200 has a fourth taper surface 2012; during the process of threadedly cooperating with the sliding sleeve assembly 200, the second taper surface 502 extrudes the first taper surface 501 to make the locking ring 510 tightly embrace the support rod assembly 100, and the fourth taper surface 2012 extrudes the third taper surface 503 to make the locking ring 510 tightly embrace the support rod assembly 100.

[0199] It can be understood that the locking ring 510 of the locking structure 500 tightly embraces the support rod assembly 100, the second taper surface 502 extrudes the first taper surface 501, the fourth taper surface 2012 extrudes the third taper surface 503, the locking sleeve 520 is threadedly connected with the sliding sleeve assembly 200, the locking structure 500 locks the sliding sleeve assembly 200 to the support rod assembly 100, and reduces the shaking of the sliding sleeve assembly 200 relative to the support rod assembly 100. When the multi-leg support is in a supporting state, the sliding sleeve assembly 200 shakes little relative to the support rod assembly 100, so that the multi-leg support can stably support on a support surface.

[0200] It can be understood that the locking ring 510 has the first taper surface 501 and the third taper surface 503, so that the locking ring 510 holds the support rod assembly 100 more tightly.

[0201] It can be understood that, in the process of being screwed with the sliding sleeve assembly 200, the movement of the locking sleeve 520 can be decomposed into two, the locking sleeve 520 moves linearly towards the sliding sleeve assembly 200, and the locking sleeve 520 rotates around the sliding sleeve assembly 200, the linear movement of the locking sleeve 520 towards the sliding sleeve assembly 200, and the locking ring 510 is limited between the locking sleeve 520 and the sliding sleeve assembly 200, so that the second taper surface 502 extrudes the first taper surface 501, and the fourth taper surface 2012 extrudes the third taper surface 503; in the process of the second taper surface 502 extruding the first taper surface 501, the locking ring 510 deforms radially inward to hold the support rod assembly 100 tightly; in the process of the fourth taper surface 2012 extruding the third taper surface 503, the locking ring 510 deforms radially inward to hold the support rod assembly 100 tightly.

[0202] It can be understood that the taper surface of the embodiment of the present application should be understood as a surface that contracts inward or expands outward in a certain direction; the taper surface can be a conical surface or a part of a conical surface, the taper surface can be an inclined conical surface or a part of an inclined conical surface; the taper surface can be a pyramid surface or a part of a pyramid surface; the taper surface can be an inclined pyramid surface or a part of an inclined pyramid surface. Specifically, the first taper surface and the second taper surface are surfaces that expand outward in the first direction, and the third taper surface and the fourth taper surface are surfaces that contract inward in the first direction.

[0203] More specifically, in the process of being screwed with the sliding sleeve assembly 200, the locking sleeve 520 moves towards the sliding sleeve assembly 200, the locking sleeve 520 abuts against the locking ring 510, and the locking ring 510 abuts against the sliding sleeve assembly 200, so that the second taper surface 502 extrudes the first taper surface 501, and the fourth taper surface 2012 extrudes the third taper surface 503.

[0204] For example, the first sleeve assembly 210 of the sliding sleeve assembly 200 has a fourth sleeve 216, the fourth sleeve 216 is connected with the first sleeve 211 (for example, integrated connection), the fourth sleeve 216 has an external thread, the locking sleeve 520 has an internal thread, the locking sleeve 520 is screwed with the fourth sleeve 216, the locking ring 510 is sleeved on the fourth sleeve 216, and the fourth taper surface 2012 is arranged on the first sleeve 211.

[0205] For example, the first taper surface 501 and the third taper surface 503 are arranged in a spaced manner.

[0206] For example, the fourth sleeve 216 cooperates with the inner wall of the main sleeve 231, the third rib 213 is connected to the fourth sleeve 216 (for example, integrally connected), the fourth rib 214 is connected to the fourth sleeve 216 (for example, integrally connected), the plug 215 is connected to the fourth sleeve 216 (for example, integrally connected), and the connecting column 212 is connected to the fourth sleeve 216 (for example, integrally connected).

[0207] Referring to FIGS. 17, 24, 25, 28-30, etc., the first direction is from the top end of the locking ring 510 to the bottom end of the locking ring 510, the taper diameter of the first taper surface 501 gradually increases along the first direction, the taper diameter of the second taper surface 502 gradually increases along the first direction, the taper diameter of the third taper surface 503 gradually decreases along the first direction, and the taper diameter of the fourth taper surface 2012 gradually decreases along the first direction; the first taper surface 501 extends to the top end of the locking ring 510, and the third taper surface 503 extends to the bottom end of the locking ring 510; the locking ring 510 is further provided with a first gap 504, the first gap 504 is through the inner wall of the locking ring 510 to the outer wall of the locking ring 510, and the first gap 504 extends from the top end of the locking ring 510 to the bottom end of the locking ring 510; in the process of the locking ring 510 tightly embracing the support rod assembly 100, the width of the first gap 504 decreases.

[0208] Understandably, the taper diameter of the first taper surface 501 gradually increases along the first direction, and the taper diameter of the second taper surface 502 gradually increases along the first direction, so that the second taper surface 502 extrudes the first taper surface 501, and the locking ring 510 deforms radially inward, so that the locking ring 510; the taper diameter of the third taper surface 503 gradually decreases along the first direction, and the taper diameter of the fourth taper surface 2012 gradually decreases along the first direction, so that the fourth taper surface 2012 extrudes the third taper surface 503, and the locking ring 510 deforms radially inward. Understandably, the movement of the locking sleeve 520 includes linear movement in the first direction in the process of being screwed with the sliding sleeve assembly 200.

[0209] Understandably, the first gap 504 is through the inner wall of the locking ring 510 to the outer wall of the locking ring 510, and the first gap 504 extends from the top end of the locking ring 510 to the bottom end of the locking ring 510, which facilitates the radial inward deformation of the locking ring 510, so that the locking ring 510 tightly embraces the support rod assembly 100.

[0210] Understandably, in the process of the locking ring 510 tightly embracing the support rod assembly 100, the width of the first gap 504 decreases.

[0211] For example, the first gap 504 extends along a straight line, or the first gap 504 extends along a curve.

[0212] In some implementations, the locking ring has a first extrusion surface, the locking sleeve has a second extrusion surface, and during the threading of the sliding sleeve assembly, the second extrusion surface extrudes the first extrusion surface to make the locking ring embrace the support rod assembly.

[0213] In particular, during the threading of the sliding sleeve assembly, the movement of the locking sleeve includes linear movement in a first direction; the first extrusion surface expands outward in the first direction, and the second extrusion surface expands outward in the first direction.

[0214] For example, the first extrusion surface is a first tapered surface, and the second extrusion surface is a second tapered surface.

[0215] In some implementations, the locking ring has a third extrusion surface, the sliding sleeve assembly has a fourth extrusion surface; and during the threading of the sliding sleeve assembly, the fourth extrusion surface extrudes the third extrusion surface to make the locking ring embrace the support rod assembly.

[0216] In particular, during the threading of the sliding sleeve assembly, the movement of the locking sleeve includes linear movement in a first direction; the third extrusion surface contracts inward in the first direction, and the fourth extrusion surface contracts inward in the first direction.

[0217] For example, the third extrusion surface is a third tapered surface, and the fourth extrusion surface is a fourth tapered surface.

[0218] Referring to FIGS. 1, 2, 5, or 31-47, etc., the support foot assembly 300 includes a support foot body 300a and a magnetic body 340 mounted to the support foot body 300a,

[0219] The support leg body 300a is rotationally connected to the sliding sleeve assembly 200, and the connecting rod 400 is rotationally connected to the support leg body 300a of the corresponding support leg assembly 300. The at least three support leg assemblies 300 can be folded into the support rod assembly 100. During the folding of the at least three support leg assemblies 300 into the support rod assembly 100, the magnetic body 340 magnetically attracts the corresponding connecting rod 400 to facilitate the folding of the at least three support leg assemblies 300 into the support rod assembly 100. In the state that the at least three support leg assemblies 300 are folded into the support rod assembly 100, the connecting rod 400 is located between the support rod assembly 100 and the corresponding support leg assembly 300, and the magnetic body 340 magnetically attracts the corresponding connecting rod 400 to keep the at least three support leg assemblies 300 in the state of being folded into the support rod assembly 100.

[0220] It can be understood that the magnetic body 340 can facilitate the folding of the support leg assembly 300 into the support rod assembly 100, thereby facilitating the storage of the multi-leg support; and the magnetic attraction of the magnetic body 340 to the connecting rod 400 can keep the support leg assembly 300 in the state of being folded into the support rod assembly 100.

[0221] For example, the magnetic body 340 is made of a permanent magnetic material, such as an aluminum-nickel-cobalt permanent magnetic alloy, an iron-chromium-cobalt permanent magnetic alloy, a permanent magnetic ferrite, a rare earth permanent magnetic material, a composite permanent magnetic material, or the like.

[0222] For example, the connecting rod 400 is at least partially made of a soft magnetic material, such as cast iron, silicon steel, carbon steel, alloy steel, or soft magnetic ferrite, or the like. The connecting rod 400 includes a soft magnetic body made of a soft magnetic material and a plating layer attached to the soft magnetic body.

[0223] In some optional implementations, as shown in FIG. 5, the support leg body 300a is provided with a clamping groove 301, and the magnetic body 340 is clamped in the clamping groove 301. Clamping the magnetic body 340 in the clamping groove 301 facilitates the installation of the magnetic body 340.

[0224] In some optional implementations, as shown in FIG. 5, the clamping groove 301 is located on the inner side of the support leg body 300a. The support leg body 300a is provided with a first installation opening 302 that is in communication with the clamping groove 301, and the magnetic body 340 can be installed in the clamping groove 301 through the first installation opening 302. In the state that the multi-leg support is supported on a support plane, the weight of the magnetic body 340 causes the magnetic body 340 to have a relative movement tendency of moving away from the first installation opening 302. This arrangement has the advantage that the magnetic body 340 is prevented from being detached from the clamping groove 301 of the support leg body 300a during the use of the multi-leg support on the ground.

[0225] For example, when the multi-legged support is supported on a support plane, the first mounting opening 302 is located above the clamping groove 301.

[0226] In some optional implementations, referring to FIGS. 32, 33, 42, etc., the support leg assembly 300 includes a first support member 310 and a second support member 320, the second support member 320 being sleeved on the first support member 310; the magnetic body 340 is located between the second support member 320 and the first support member 310. The magnetic body 340 is between the second support member 320 and the first support member 310, so that the magnetic body 340 is not easily separated from the support leg assembly 300.

[0227] Further, referring to FIGS. 32-41, the second support member 320 is provided with a mounting groove 303 and a second mounting opening 304, the second mounting opening 304 being in communication with the mounting groove 303; before the second support member 320 is sleeved on the first support member 310, the magnetic body 340 can be loaded into the mounting groove 303 through the second mounting opening 304; after the second support member 320 is sleeved on the first support member 310, the first support member 310 closes the second mounting opening 304. The second mounting opening 304 facilitates the installation of the magnetic body 340 on the support leg assembly 300.

[0228] For example, the first support member 310 is provided with an assembly cavity 305, a first end of the first support member 310 is provided with a first insertion opening 306a, the first insertion opening 306a is in communication with the assembly cavity 305, and the second support member 320 is inserted into the assembly cavity 305 of the first support member 310 through the first insertion opening 306a, so that the second support member 320 is sleeved on the first support member 310.

[0229] Further, referring to FIGS. 32-41, the support leg assembly 300 includes a third support member 330, the third support member 330 being sleeved on the first support member 310; the second support member 320 can be inserted into the first support member 310 from a first end of the first support member 310, and the third support member 330 can be inserted into the first support member 310 from a second end of the first support member 310; the third support member 330 is rotationally connected with the sliding sleeve assembly 200, and the second support member 320 is rotationally connected with the corresponding connecting rod 400. Obviously, the second support member 320 can be separated from the first support member 310 from the first end of the first support member 310, and the third support member 330 can be separated from the first support member 310 from the second end of the first support member 310.

[0230] For example, the second end of the first support 310 is provided with a second insertion opening 306b, which is in communication with the assembly cavity 305, and the second support 320 is inserted into the assembly cavity 305 of the first support 310 through the second insertion opening 306b, so that the third support 330 is sleeved on the first support 310.

[0231] For example, the first support 310 is made of a profiled material, such as an aluminum alloy profiled material.

[0232] It can be understood that the support leg assembly 300 is provided in the structural form of the first support 310, the second support 320 and the third support 330, and the second support 320 is insertably assembled in the first support 310, and the third support 330 is insertably assembled in the first support 310, so as to facilitate the assembly of the support leg assembly 300; and the third support 330 is rotationally connected with the sliding sleeve assembly 200, and the second support 320 is rotationally connected with the corresponding connecting rod 400, so as to facilitate the installation of the support leg assembly 300 on the multi-leg support.

[0233] For example, the third support 330 is first rotationally connected with the sliding sleeve assembly 200, and the second support 320 is rotationally connected with the connecting rod 400; then the third support 330 is inserted into the first support 310, and the second support 320 is inserted into the first support 310; finally, the end of the connecting rod 400 away from the support leg assembly 300 is rotationally installed on the support rod assembly 100.

[0234] In some optional implementations, referring to FIGS. 32-41, the second support 320 is provided with a first clamping portion 321, the third support 330 is provided with a second clamping portion 332, and the first clamping portion 321 clamps with the second clamping portion 332; the first clamping portion 321 has a clamping protrusion, and the second clamping portion 332 has a clamping groove, or the first clamping portion 321 has a clamping groove, and the second clamping portion 332 has a clamping protrusion. The second support 320 has a first limiting protrusion, and the third support 330 has a second limiting protrusion, and the first support 310 is limited between the first limiting protrusion and the second limiting protrusion so that the first support 310 cannot slide relative to the whole of the second support 320 and the third support 330. The first clamping portion 321 clamps with the second clamping portion 332, so that the second support 320 and the third support 330 are as a whole, and the first support 310 is limited between the first limiting protrusion and the second limiting protrusion, so that the second support 320 and the third support 330 as a whole cannot slide relative to the first support 310, so that the integrity of the support leg assembly 300 is better, the support leg assembly 300 is not easy to shake, and the multi-leg support is more stable when supporting the electronic terminal.

[0235] In other implementations, the friction between the second support 320 and the first support 310 limits the installation of the second support 320 on the first support 310, and the friction between the third support 330 and the first support 310 limits the installation of the third support 330 on the first support 310.

[0236] In some optional implementations, referring to FIG. 31, FIG. 42-FIG. 47, etc., one of the support leg assemblies 300 is an auxiliary support leg assembly 300, the third support 330 of the auxiliary support leg assembly 300 is sleeved on the first support 310 of the auxiliary support leg assembly 300; the third support 330 of the auxiliary support leg assembly 300 is insertable into the first support 310 of the auxiliary support leg assembly 300, the assembly protrusion 333 of the third support 330 of the auxiliary support leg assembly 300 is provided with an assembly groove 309, the assembly groove 309 is used for mounting an auxiliary accessory, the first support 310 of the auxiliary support leg assembly 300 is provided with a second avoiding opening 308, the second avoiding opening 308 avoids the assembly protrusion 333 in the process that the third support 330 of the auxiliary support leg assembly 300 is inserted into the first support 310 of the auxiliary support leg assembly 300; in the state that the third support 330 of the auxiliary support leg assembly 300 is sleeved on the first support 310 of the auxiliary support leg assembly 300, the assembly protrusion 333 is accommodated in the second avoiding opening 308. Understandably, the assembly groove 309 is arranged on the assembly protrusion 333 of the third support 330, the assembly protrusion 333 is accommodated in the second avoiding opening 308, so that the structure of the auxiliary support leg assembly 300 is compact and occupies a small volume; and the second avoiding opening 308 of the first support 310 is used for avoiding the assembly protrusion 333 in the assembly process, so as to facilitate the installation of the third support 330 on the first support 310.

[0237] For example, the auxiliary accessory can be a remote controller, a camera, etc., and preferably, the auxiliary accessory is a remote controller in communication connection with the electronic terminal.

[0238] In some optional implementations, referring to FIG. 40, FIG. 45, etc., the second support 320 is rotationally connected with the corresponding connecting rod 400, the first support 310 has a first avoiding opening 307, and the second support 320 is insertable into or detachable from the first support 310; the first avoiding opening 307 avoids the connecting rod 400 in the process that the second support 320 is inserted into or detached from the first support 310; in the state that the second support 320 is sleeved on the first support 310, the connecting rod 400 is rotationally connected with the corresponding second support 320 through the first avoiding opening 307. The rotationally connecting the connecting rod 400 with the second support 320 through the first avoiding opening 307 makes the structure of the multi-leg support compact; and the first avoiding opening 307 is also used for avoiding the connecting rod 400 from blocking the insertion of the second support 320 into the first support 310, thereby facilitating the installation of the support leg assembly 300.

[0239] In some implementations, when the at least three support leg assemblies are unfolded relative to the support rod assembly, the user holding the sliding sleeve assembly and lifting the sliding sleeve assembly can cause the at least three support leg assemblies to fold relative to the support rod assembly; during the process that the user holding the sliding sleeve assembly and lifting the sliding sleeve assembly causes the at least three support leg assemblies to fold relative to the support rod assembly, the magnetic attraction of the magnetic body to the corresponding connecting rod promotes the folding of the at least three support leg assemblies to the support rod assembly.

[0240] It can be understood that the user holding the sliding sleeve assembly and lifting the sliding sleeve assembly causes the support leg assemblies of the multi-leg support to fold, thereby facilitating the use of the multi-leg support; and during the folding of the support leg assemblies, the magnetic body can also promote the folding of the at least three support leg assemblies, thereby further facilitating the use of the multi-leg support.

[0241] For example, the user lifts the sliding sleeve assembly, and the multi-leg support is suspended or contacts the support surface.

[0242] In some implementations, during the process that the user holding the sliding sleeve assembly and lifting the multi-leg support causes the at least three support leg assemblies to fold relative to the support rod assembly, the weight of the moving assembly promotes the folding of the at least three support leg assemblies to the support rod assembly; the moving assembly includes the support rod assembly and the support leg assemblies. The weight of the moving assembly promotes the folding of the at least three support leg assemblies, thereby further facilitating the use of the multi-leg support.

[0243] For example, the moving assembly further includes a connecting arm, a support piece, an electronic terminal, etc.

[0244] In some implementations, during the process that the user holding the sliding sleeve assembly and lifting the multi-leg support causes the at least three support leg assemblies to fold relative to the support rod assembly, the inertia of the moving assembly promotes the folding of the at least three support leg assemblies to the support rod assembly; the moving assembly includes the support rod assembly and the support leg assemblies.

[0245] It can be understood that the inertia of the moving assembly refers to the property of the moving assembly remaining stationary or moving at a constant speed in a straight line, and the inertia of the moving assembly refers to the effect brought by the inertia of the moving assembly.

[0246] For example, during the process that the user holds the sleeve assembly and lifts the multi-leg support so that the at least three support leg assemblies are retracted relative to the support rod assembly, the speed of the sleeve assembly changes, the moving assembly still keeps the original speed, and the inertial action of the moving assembly promotes the at least three support leg assemblies to be retracted to the support rod assembly. Specifically, during the process that the user holds the sleeve assembly and lifts the multi-leg support so that the at least three support leg assemblies are retracted relative to the support rod assembly, the sleeve assembly has a certain speed from static, the moving assembly still keeps static, and the inertial action of the moving assembly promotes the at least three support leg assemblies to be retracted to the support rod assembly.

[0247] The embodiment of the present application also provides an electronic terminal support device, referring to FIG. 1 or FIG. 31, which comprises a supporting piece 600 and the multi-leg support of any one of claims 1-21, and the supporting piece 600 is installed on the support rod assembly 100 of the multi-leg support.

[0248] For example, the supporting piece 600 is directly or indirectly installed on the support rod assembly 100, for example, a connecting arm 700 is installed on the support rod assembly 100, and the connecting arm 700 is installed on the support rod assembly 100. Specifically, the supporting piece 600 is rotatably installed on the connecting arm 700, and the supporting piece 600 rotates relative to the connecting arm 700 to adjust the width of the electronic terminal (for example, the horizontal width, the vertical width, the oblique width, etc.), and more specifically, the supporting piece 600 can rotate around the connecting arm 700. Specifically, the connecting arm 700 is rotatably installed on the support rod assembly 100, and the connecting arm 700 rotates relative to the support rod assembly 100 to adjust the use angle of the electronic terminal, and when the electronic terminal support needs to be stored, the connecting arm 700 can be folded on the support rod assembly 100, or the connecting arm 700 is folded on the support leg assembly 300 in the retracted state.

[0249] For example, the supporting piece 600 can be a clamp for clamping the electronic terminal, and the clamp comprises a clamp body 610 and two clamping parts 620, and the two clamping parts 620 are clamped on the opposite two sides of the electronic terminal respectively, the clamp body 610 can be elastically extended and retracted to adjust the clamping width of the clamp, and the clamping part 620 can be stored in the clamp body 610.

[0250] For example, the supporting piece 600 is a suction cup for adsorbing the electronic terminal, for example, the suction cup can be adsorbed on the back of the electronic terminal.

[0251] For example, the supporting piece 600 is a magnetic piece for magnetically attracting the electronic terminal, and the magnetic piece can be an electromagnet or a permanent magnet.

[0252] For example, the supporting piece 600 is a tray for supporting the electronic terminal, and the electronic terminal is placed on the tray.

[0253] For example, the supporting piece 600 is a clamping piece for clamping the electronic terminal, and the clamping piece is used for clamping the electronic terminal.

[0254] With reference to FIGS. 1-47, a multi-leg support for supporting an electronic terminal includes a support rod assembly 100, a sliding sleeve assembly 200, at least three support leg assemblies 300, and at least three connecting rods 400. The sliding sleeve assembly 200 is slidably sleeved on the support rod assembly 100. The at least three support leg assemblies 300 are respectively rotationally connected to the sliding sleeve assembly 200. The at least three connecting rods 400 respectively correspond to the at least three support leg assemblies 300. The at least three connecting rods 400 are respectively rotationally connected to the support rod assembly 100. The at least three connecting rods 400 are respectively rotationally connected to the corresponding support leg assemblies 300. Each of the connecting rods 400 is between the support rod assembly 100 and the corresponding support leg assembly 300. The at least three support leg assemblies 300 are foldable to the support rod assembly 100.
