[0035] Reference Figure 1 An automatic deployment mechanism includes a main body 100, a support leg 500, and a locking structure 800. One end of the support leg 500 is rotatably connected to the main body 100, and the other end of the support leg 500 can be rotated toward or away from the outer wall of the main body 100. The locking structure 800 is provided on the main body 100 or the support leg 500, and can relatively fix the support leg 500 and the main body 100 or release the fixing effect between the support leg 500 and the main body 100. The locking structure 800 includes an unlocking portion 890, which is provided at the bottom of the main body 100 and can release the fixing effect between the support leg 500 and the main body 100. The unlocking portion 890 is exposed relative to the main body 100 and the support leg 500. When the photography stand needs to be carried, the support leg 500 can be flipped closer to the main body 100, so that the support leg 500 and the main body 100 are close to overlapping. Subsequently, the main body 100 and the legs 500 can be relatively fixed by the locking structure 800, so that the photography stand can remain in a portable state. When the photography stand needs to be used, the main body 100 can be placed on a support surface such as the ground. When the main body 100 contacts the support surface through its bottom, the support surface will apply force to the unlocking portion 890, causing the unlocking portion 890 to release the locking relationship between the legs 500 and the main body 100, thereby allowing the legs 500 to move and unfold, so that the main body 100 can be supported by the legs 500. Since the photography stand can be unfolded, it is only necessary to place the main body 100 on a support surface such as the ground, and the unlocking portion 890 will be activated and the legs 500 will unfold. Therefore, the user can achieve the unfolding effect of the photography stand through a simple placement action, thereby effectively improving the convenience of using the photography stand.

[0036] Specifically, there are three legs 500, each of which is connected to the main body 100 via a locking structure 800. The end of the main body 100 away from the legs 500 is provided with a connecting structure 700 for connecting a photographic device.

[0037] In certain embodiments, reference Figure 2 The support structure 300 includes a support rod 320, the ends of which are hingedly connected to the main body 100 and the support leg 500, respectively. The support rod 320 can further support the main body 100 and the support leg 500. Therefore, when the support spring 310 relatively expands the main body 100 and the support leg 500, the main body 100 and the support leg 500 can maintain a relatively expanded state under the support of the support rod 320, thereby facilitating the support leg 500 to stably support the main body 100 and the photographic equipment connected to the main body 100.

[0038] It is conceivable that the number of support rods 320 , support springs 310 and support legs 500 is in one-to-one correspondence, thereby ensuring that each support leg 500 can be stretched by the support spring 310 and supported by the support rod 320 .

[0039] In certain embodiments, reference Figure 3 A core rod 510 is provided inside the support leg 500. The core rod 510 is provided with a first connection position and a second connection position, and the first connection position and the second connection position are separated by a distance. The support spring 310 is connected to the first connection position, and the support rod 320 is connected to the second connection position. The core rod 510 can connect the support leg 500, the support spring 310, and the support rod 320 inside the support leg 500, and the division of the first connection position and the second connection position can achieve the mutual positioning effect between the support spring 310 and the support rod 320. Since there is a distance between the first connection position and the second connection position, it can effectively ensure that the support leg 500 can obtain a multi-point support effect, and the force exerted by the support rod 320 on the support leg 500 and the support spring 310 can be staggered, thereby avoiding the problem of mutual interference of the forces, thereby ensuring that the support rod 320 can rotate smoothly and support the support leg 500 and the main body 100.

[0040] Specifically, each end of the support spring 310 is provided with a circular hook, which is rotatably connected to the core rod 510 and the main body 100 through the circular hook. When the legs are deployed, they will drive the support spring 310 to rotate. The circular hook allows the support spring 310 to rotate smoothly, thereby facilitating the mutual support between the legs and the main body 100.

[0041] In certain embodiments, reference Figure 4The locking structure 800 includes an unlocking portion 890, which is disposed at the bottom of the main body 100 and is capable of releasing the fixing effect between the supporting leg 500 and the main body 100. The unlocking portion 890 is exposed relative to the main body 100 and the supporting leg 500. When the photographic stand is to be used, the main body 100 can be placed on a supporting surface such as the ground. When the main body 100 contacts the supporting surface through its bottom, the supporting surface will apply force to the unlocking portion 890, thereby releasing the locking relationship between the supporting leg 500 and the main body 100, thereby allowing the supporting leg 500 to move and unfold, so that the main body 100 can be supported by the supporting leg 500.

[0042] In certain embodiments, reference Figure 6 and Figure 7 The locking structure 800 includes a first snap-in portion 855 and a second snap-in portion 553. The first snap-in portion 855 is provided on the main body 100, and the second snap-in portion 553 is provided on the support leg 500. When the support leg 500 moves closer to the main body 100, the first snap-in portion 855 and the second snap-in portion 553 can be mutually engaged and fixed. When the first snap-in portion 855 and the second snap-in portion 553 are mutually engaged, the main body 100 and the support leg 500 can be directly and effectively fixed to each other, thereby smoothly achieving the effect of fixing the support leg 500 to the main body 100. In addition, since the mutual engagement between the first snap-in portion 855 and the second snap-in portion 553 also has the advantage of easy assembly and disassembly, the assembly and disassembly operation between the support leg 500 and the main body 100 can also be carried out more conveniently.

[0043] It is conceivable that the locking structure 800 may also be composed of other components, such as an electromagnet component for locking. The specific implementation is not exclusive and can be adjusted accordingly according to actual conditions, and is not limited here.

[0044] In certain embodiments, reference Figure 6 and Figure 7The locking structure 800 includes a snap seat 850 movably disposed at the bottom of the main body 100, with a first snap portion 855 located at the bottom of the snap seat 850. The support leg 500 can drive the second snap portion 553 to rotate to the bottom of the snap seat 850, thereby interlocking the first snap portion 855 with the second snap portion 553. The snap seat 850 can drive the first snap portion 855 to move relative to the main body 100, thereby smoothly locking and unlocking the main body 100 and the support leg 500. During the rotation of the support leg 500, the first snap portion 855 and the second snap portion 553 will move closer to or farther from each other. When and only when the first latch portion 855 and the second latch portion 553 approach each other due to the rotation of the support leg 500, and the latch seat 850 drives the first latch portion 855 to move close to the second latch portion 553, the first latch portion 855 can be engaged with the second latch portion 553, and the effect of locking the main body 100 and the support leg 500 is achieved.

[0045] Specifically, the buckle seat 850 is movably mounted on the bottom of the main body 100 and can slide relative to the length direction of the main body 100. When the buckle seat 850 drives the first buckle portion 855 to move toward the bottom of the main body 100, the first buckle portion 855 and the second buckle portion 553 are engaged with each other.

[0046] In certain embodiments, reference Figure 8 and Figure 9 A positioning post 830 and a return spring 835 are provided between the snap seat 850 and the main body 100. The positioning post 830 is connected to the main body 100, and a stop portion 870 is provided at the end of the positioning post 830. The snap seat 850 is sleeved on the outer periphery of the positioning post 830. The stop portion 870 and the return spring 835 are respectively located on both sides of the snap seat 850 and are both capable of abutting against the snap seat 850. The snap seat 850 is sleeved on the outer periphery of the positioning post 830 and slides back and forth relative to the axial direction of the positioning post 830, thereby driving the first snap portion 855 to move closer to or away from the second snap portion 553. The positioning post 830 can guide the movement of the snap seat 850 and cooperate with the stop portion 870 to limit the movement of the snap seat 850, thereby preventing the snap seat 850 from falling off due to excessive movement. The return spring 835 can continuously apply elastic force to the snap seat 850, thereby driving the snap seat 850 to continuously apply thrust to the first snap portion 855 to snap into engagement with the second snap portion 553, thereby ensuring that the first snap portion 855 can continuously and stably snap into engagement with the second snap portion 553.

[0047] Specifically, the return spring 835 is located above the buckle seat 850 , and the return spring 835 is located between the main body 100 and the buckle seat 850 ; the blocking portion 870 is located below the buckle seat 850 .

[0048] In certain embodiments, reference Figure 8 and Figure 9 The unlocking portion 890 is mounted on the bottom of the snap seat 850 and can push the snap seat 850 to slide back and forth along the length of the positioning column 830. The end of the support leg 500 is provided with a foot pad 550, and the second snap portion 553 is located on the foot pad 550. The foot pad 550 is bent relative to the support leg 500. When the support leg 500 moves close to the main body 100, the foot pad 550 can drive the second snap portion 553 to move and extend into the main body 100 through its bent portion. When the photography stand is in the folded state, the bent portion of the foot pad 550 will extend into the snap seat 850, causing the first snap portion 855 and the second snap portion 553 to interlock. When the photography stand is unfolded, the main body 100 can be placed on a support surface first. During this process, the unlocking portion 890 will contact the support surface and withstand the force transmitted by the support surface. This force will push the buckle seat 850 to move, and make the first buckle portion 855 and the second buckle portion 553 move away from each other, thereby achieving the effect of unlocking the support leg 500.

[0049] Specifically, after the support leg 500 rotates to the maximum extent in a direction away from the main body 100, the bent portion of the foot pad 550 will be in a horizontal orientation, so that the foot pad 550 and the support leg 500 can be supported by this portion.

[0050] In certain embodiments, reference Figure 1 The main body 100 is provided with a connecting seat 470 on its periphery. The connecting seat 470 can slide back and forth along the length of the main body 100. The support leg 500 is hinged to the connecting seat 470. A fixing structure 400 for fixing the connecting seat 470 is provided between the connecting seat 470 and the main body 100. The connecting seat 470 allows the connection position of the support leg 500 and the main body 100 to be changed relative to the main body 100. As a result, the support leg 500 and the main body 100 can not only be adjusted by rotation, but can also be further adjusted by sliding the connecting seat 470. After the support leg 500 is rotated to be flush with the main body 100, the connecting seat 470 can be slid so that the support leg 500 and the main body 100 in the flush state overlap with each other, thereby directly and effectively reducing the spread between the main body 100 and the support leg 500, thereby facilitating the carrying and transportation of the photographic stand.

[0051] In certain embodiments, reference Figure 2The fixing structure 400 includes a fastening hoop 430 disposed on a connecting seat 470. The fastening hoop 430 is sleeved on the outer circumference of the main body 100. The fastening hoop 430 is provided with a deformation notch 435. The fastening hoop 430 can be deformed and expanded at the deformation notch 435 to clamp or loosen the main body 100. When the fastening hoop 430 is compressed, it will contract and deform at the deformation notch 435, thereby clamping the main body 100. Because the fastening hoop 430 is disposed on the connecting seat 470, when the fastening hoop 430 clamps the main body 100, it can directly and effectively achieve a relative fixation effect between the connecting seat 470 and the main body 100, thereby achieving relative fixation between the support leg 500 and the main body 100.

[0052] Specifically, the fastening hoop 430 is made of elastic metal, and the fastening hoop 430 is fixedly connected to the connecting seat 470 .

[0053] In certain embodiments, reference Figure 2 The outer circumference of the fastening hoop 430 is provided with a threaded inner sleeve 450 and a threaded outer sleeve 410. The threaded inner sleeve 450 is provided on the outer circumference of the fastening hoop 430, and the deformation notch 435 partially extends outside the threaded inner sleeve 450. The threaded outer sleeve 410 is threadedly connected to the threaded inner sleeve 450, and the threaded outer sleeve 410 can move toward and squeeze the deformation notch 435. When the threaded outer sleeve 410 rotates, it moves relative to the threaded inner sleeve 450, gradually approaching or moving away from the deformation notch 435 on the fastening hoop 430. When the threaded outer sleeve 410 moves away from the deformation notch 435, the fastening hoop 430 will expand the deformation notch 435 under its own elastic force and relax the main body 100, thereby allowing the connecting base 470 to slide relative to the support leg 500. When the threaded sleeve 410 approaches the fastening hoop 430 at the deformation notch 435, the fastening hoop 430 will be compressed and shrink at the deformation notch 435, thereby clamping the main body 100, thereby achieving the effect of relative fixation between the main body 100 and the support leg 500.

[0054] A second aspect of the present invention provides an embodiment of a photographic stand including the aforementioned automatic deployment mechanism. When the photographic stand is to be carried, the legs 500 can be flipped closer to the main body 100, so that the legs 500 and the main body 100 are nearly overlapping. The main body 100 and the legs 500 can then be secured relative to each other using the locking structure 800, thereby maintaining a portable position. When the photographic stand is to be used, the main body 100 can be placed on a support surface such as the ground. When the main body 100 contacts the support surface through its bottom, the support surface applies force to the unlocking portion 890, causing the unlocking portion 890 to release the locking relationship between the legs 500 and the main body 100, thereby allowing the legs 500 to move and deploy, thereby supporting the main body 100. To deploy the photographic stand, simply place the main body 100 on a support surface such as the ground, and the unlocking portion 890 will activate, causing the legs 500 to deploy. Therefore, the user can achieve the unfolding effect of the photographic stand through a simple placement action, thereby effectively improving the convenience of using the photographic stand.
