[0038] The present invention proposes a multifunctional bracket, which can be used in a variety of indoor and outdoor scenarios. It is suitable for supporting small-load digital products such as smart phones and tablet computers. The angle and height can be adjusted according to user needs. It can also be used to support large-load devices such as projectors and laser TVs. The arbitrarily adjustable supporting gimbal can be switched to a large-load gimbal, which can also meet outdoor needs. It can be used to support cameras, astronomical telescopes and other equipment, and has stable support and wind resistance.

[0039] Reference Figure 1 and Figure 2 In one embodiment of the present invention, the multifunctional bracket includes a support assembly 10, a pan-tilt assembly 20 and a tripod assembly 30, the support assembly 10 has a first end and a second end opposite to each other; the pan-tilt assembly 20 is telescopically arranged at the first end of the support assembly 10, and the pan-tilt assembly 20 is used to place a load device; the tripod assembly 30 is switchably arranged at the second end of the support assembly 10 between a supporting position and a storage position.

[0040] In this embodiment, the support assembly 10 can be assembled from multiple parts, which can be plastic parts, metal parts or a combination thereof, which are not limited here. Preferably, the support assembly 10 can adopt a long cylindrical structure. This hollow structure can save material usage and ensure overall stability.

[0041] The pan-tilt assembly 20 may include a telescopic part and a support platform. The telescopic part may be a spring hose, a sliding mechanism, a lifting mechanism, etc. The support platform may be adapted and designed according to the main application product, or may be made into a variety of support platform structures that can be easily replaced by users, which is not limited here.

[0042] The tripod assembly 30 can be composed of three or more supporting legs, which can be evenly distributed along the peripheral wall of the supporting assembly 10 and can be arranged at the near-ground end of the supporting assembly 10 through a folding mechanism, a telescopic mechanism, etc., and its specific structure is not limited here.

[0043] It can be understood that the present invention sets the support component 10 of the multifunctional bracket at the first and second ends opposite to each other, the pan-tilt component 20 is telescopically set at the first end of the support component 10, the pan-tilt component 20 is used to place the load device, and the tripod component 30 is switchably set at the second end of the support component 10 between the support position and the storage position, so that the pan-tilt component 20 can be telescopically converted between different support positions, and the tripod component 30 can well support the entire pan-tilt component 20 and the load thereon, thereby realizing the function of the bracket supporting various electronic devices, which is convenient for users to use. At the same time, by setting the tripod component 30 switchably between the support position and the storage position at the second end of the support component 10, the storage function of the tripod component 30 is realized, which improves the convenience of user use.

[0044] In order to further enhance the stability of the multifunctional bracket and enable the pan / tilt assembly 20 to be adjusted between multiple positions so as to carry small loads and large loads, in one embodiment, reference is made to Figures 2 to 4 The support assembly 10 may include a pull rod assembly 11, a sleeve assembly 12 and a locking knob assembly 13. The pull rod assembly 11 includes an outer pull rod 111 and a first eccentric rod 112 and a second eccentric rod 113 telescopically connected to the outer pull rod 111. The outer end of the second eccentric rod 113 is the first end of the support assembly 10; the sleeve assembly 12 is sleeved on the outer end of the outer pull rod 111, and the pan-tilt assembly 20 is connected to the outer end of the second eccentric rod 113 and movably embedded in the sleeve assembly 12; the locking knob assembly 13 is screwed on the sleeve assembly 12 to loosen or lock the pan-tilt assembly 20.

[0045] In this embodiment, the outer diameter of the first eccentric rod 112 is smaller than the outer rod 111, and the outer diameter of the second eccentric rod 113 is smaller than the first eccentric rod 112. The first eccentric rod 112 can be received in the outer rod 111, and the second eccentric rod 113 can be received in the first eccentric rod 112. In addition, by providing the first eccentric rod 112 and the second eccentric rod 113, the overall center of gravity of the multifunctional bracket can be more stable in the supporting scenario where the first eccentric rod 112 and the second eccentric rod 113 are extended, thereby greatly improving the stability of the multifunctional bracket.

[0046] In order to improve the stability and ease of use of the multifunctional bracket, in one embodiment, reference Figure 3 and Figure 4 The sleeve assembly 12 may include a bracket sleeve 121 and a nut 122 embedded in the bracket sleeve 121. The locking knob assembly 13 is provided with an inner stud 131 threadedly adapted to the position of the nut 122 so that the locking knob assembly 13 is threadedly connected to the sleeve assembly 12.

[0047] Further, in one embodiment, reference is made to Figure 3 and Figure 4 The locking knob assembly 13 also includes a knob 132 and a stop block 133. One end of the inner stud 131 is fixed in the knob 132, and the other end of the inner stud 131 is screwed into the nut 122 and abuts against the stop block 133. Figure 7 and Figure 8 As shown, the limit block 133 is connected to the rod assembly 11 to limit the axial telescopic movement of the rod assembly 11. This arrangement can enhance the stability of the entire bracket, and also facilitate the user to lock the pan / tilt assembly 20 and adjust the appropriate position to facilitate the user to use the bracket.

[0048] In order to realize the function of adjusting the pan / tilt head to any angle, so as to facilitate users to use the multi-functional bracket to support products such as smart phones and cameras, in one embodiment, reference Figures 1 to 3 The gimbal assembly 20 may include a gimbal cover 21 and a spring hose 22. The gimbal cover 21 is connected to the outer end of the second eccentric rod 113 through the spring hose 22. The spring hose 22 can be stored in the pull rod assembly 11, and when the spring hose 22 is in the stored state, the gimbal cover 21 is threadedly connected to the bracket sleeve 121.

[0049] Among them, the gimbal cover 21 and the second eccentric rod 113 are connected by a spring hose 22. On the one hand, the function of adjusting the gimbal to any angle is realized. On the other hand, the length of the entire support assembly 10 can also be lengthened to use a wider range of application scenarios, thereby improving practicality.

[0050] In this embodiment, the multifunctional bracket is an integrated portable lazy bracket, and the spring hose 22 is hidden inside the second eccentric rod 113. After being stored, it is an integrated shape, which is convenient to carry and has a neat appearance. Pulling out the spring hose 22 can adjust the position of the pan / tilt head at will, and retracting and locking it in the sleeve can form an integrated strong and stable pan / tilt head; it can also be used as a bracket for projectors, aurora TVs, etc., which greatly enriches the use scenarios.

[0051] In this embodiment, Figure 7 and Figure 8 As shown, the limit block 133 can be used to limit and tighten the spring hose 22 of the pan / tilt assembly 20 under the control of the knob 132, thereby limiting the axial telescopic movement of the pull rod assembly 11 to provide stability for the multifunctional bracket.

[0052] Main references Figure 4 In one embodiment, the pan / tilt assembly 20 may further include an inner tube tail plug 23, and the spring hose 22 is connected to the outer end of the second eccentric rod 113 through the inner tube tail plug 23. Such a configuration can facilitate the connection of the spring hose 22 and the second eccentric rod 113 without affecting the telescopic movement of the second eccentric rod 113, and can also improve the stability of the entire bracket.

[0053] In order to improve the stability of the pan / tilt of the multifunctional bracket and facilitate the connection of the support assembly 10, in one embodiment, the main reference Figure 3 and Figure 4 The gimbal cover 21 may include a gimbal knob 211, a stud 212 and a cover plate 213. The cover plate 213 is covered on the gimbal knob 211. The gimbal knob 211 is threadedly connected to the bracket sleeve 121. One end of the stud 212 is fixed on the gimbal knob 211, and the other end of the stud 212 extends out of the gimbal knob 211 through the cover plate 213.

[0054] In this embodiment, the pan-tilt knob 211 and the cover plate 213 can support small-load and large-load products. At the same time, by setting a spiral structure, the pan-tilt assembly 20 can be conveniently threadedly connected to the bracket sleeve 121 to achieve better stability.

[0055] During operation, the pan-tilt cover 21 is rotated and tightened in the outer pull rod 111, and the spring hose 22 can form a large-load pan-tilt, which can be used to place relatively heavy devices such as projectors and smart TVs; the pan-tilt cover 21 is rotated, twisted and pulled up to form a free pan-tilt, which can be used to place relatively light products such as smart phones and tablets.

[0056] In order to improve the stability of the multifunctional bracket when supporting a large load product, in one embodiment, reference Figures 1 to 4 The tripod assembly 30 may include a plurality of tripod handles 31 and a plurality of support rods 32. The plurality of tripod handles 31 are respectively arranged on the peripheral wall of the outer rod 111 through the tripod seat 40. The support rods 32 are arranged one-to-one with the tripod handles 31. One end of the support rod 32 is arranged on the outer rod 111 through the fixing seat 50, and the other end of the support rod 32 is slidably connected with the tripod handle 31. In this way, by providing a plurality of support rods 32 with a sliding structure, the tripod handle 31 can be slidably switched between the supporting position and the storage position, thereby improving the convenience of use of the multifunctional bracket. While ensuring a certain stability, it is also convenient for users to store and carry.

[0057] Further, in some embodiments, reference Figure 3 and Figure 4 The tripod seat 40 may include a tripod surface cover 41 and a tripod bottom cover 42, the tripod surface cover 41 is fixed on the outer pull rod 111, and the tripod bottom cover 42 is covered on the tripod surface cover 41; the tripod assembly 30 also includes a first ground nail 43 and a second ground nail 44, the first ground nail 43 is arranged on the near-ground end of the tripod surface cover 41, and a second ground nail 44 is provided on the near-ground end of each tripod handle 31.

[0058] It should be noted that the first ground nail 43 and the second ground nail 44 are configured accessories. In outdoor scenes, the first ground nail 43 and the second ground nail 44 are used by inserting them into the corresponding ground nail holes on the bracket.

[0059] It can be understood that, due to the provision of the first ground nail 43 and the second ground nail 44, when outdoors, the multifunctional bracket can be used to support large-load products such as projectors, cameras, and astronomical telescopes.

[0060] In order to facilitate the adjustment of the tripod assembly 30, so as to facilitate the user to flexibly adjust the tripod handle 31 to switch between the storage position and the support position, in one embodiment, reference is made to Figures 3 to 6 The fixed base 50 includes a handle base 51 and a fixed rotating ring 52. The handle base 51 is sleeved on the outer pull rod 111. The ends of multiple support rods 32 are spaced apart on the handle base 51. The fixed rotating ring 52 is sleeved on the outer pull rod 111 and is threadedly connected to the handle base 51 to loosen or lock the handle base 51 and the outer pull rod 111, and adjust the opening angles of multiple tripod handles 31.

[0061] In this embodiment, the handle seat 51 is squeezed and held tightly to the outer pull rod 111 by rotating the fixed rotating ring 52, and the tripod handle 31 can be tightened and prevented from loosening by the support rod 32; when opening, the fixed rotating ring 52 is rotated clockwise or counterclockwise to open the tripod, and then the fixed rotating ring 52 is rotated in the opposite direction to lock it, and the tripod handle 31 can be tightened by the support rod 32 to maintain a firmly locked state, so that the tripod assembly 30 can firmly support the pan / tilt assembly 20 and the load thereon.

[0062] During use, when the tripod assembly 30 is in the storage position, it can be adjusted to the supporting state by opening the tripod handle 31. During this process, the support rod 32 moves downward and supports the tripod handle 31. The handle seat 51 and the outer rod 111 can be loosened by rotating the fixed rotating ring 52, and the tripod handle 31 or the fixed seat 50 can be moved up and down to adjust the opening angle of the tripod handle 31, thereby adjusting the supporting range of the tripod handle 31. After adjusting to a suitable supporting angle, the fixed rotating ring 52 is rotated to lock and fix the handle seat 51 and the outer rod 111. When the tripod assembly 30 is in the supporting position, the fixed rotating ring 52 can be loosened first, and then the tripod handle 31 is pushed upward to switch its self-supporting state to the storage state. During this process, the tripod handle 31 drives the support rod 32 to move upward to complete the storage of the tripod assembly 30.

[0063] It should be noted that, according to different usage scenarios, the adjustable tripod assembly 30 can open different support areas. Holes are reserved at the bottom of the tripod bottom cover 42 and the end of the tripod handle 31. Whether ground nails are needed for auxiliary reinforcement can be determined based on whether the usage site is a lawn, beach, mud, etc.

[0064] It is worth mentioning that the overall shape of the multifunctional bracket is not limited to a cylindrical shape, but may also be a square or other shapes, and the tripod assembly 30 is not limited to a tripod, but may also be a four-legged or more-legged one.

[0065] The above descriptions are only optional embodiments of the present invention, and are not intended to limit the patent scope of the present invention. All equivalent structural changes made using the contents of the present invention's specification and drawings, or directly / indirectly applied in other related technical fields, are included in the patent protection scope of the present invention.
