[0041] The present invention Figures 1 to 4 As shown, a small and portable gravity stand includes a base 10, a clamping mechanism 20 movably mounted on the base 10 for clamping electronic products, and an elastic element 30 connected between the clamping mechanism 20 and the base 10, wherein:

[0042] The base 10 is T-shaped and includes a transverse portion 11 and a vertical portion 12 . A vertical slide groove 13 is disposed on the vertical portion 12 . A fixing seat 40 for fixing the bracket is disposed at the rear end of the base 10 .

[0043] The clamping mechanism 20 includes a left clamping arm 21, a right clamping arm 22 and a bottom support arm 23 which are linked to each other; the left clamping arm 21 has a left clamping portion 211 at the upper end and a winding post 212 at the lower end, and the left clamping arm 21 is rotatably mounted on the left side of the transverse portion 11 through the winding post 212, and a torsion spring 31 is sleeved on the winding post 212 (the torsion spring 31 is the above-mentioned elastic element 30), and the two ends of the torsion spring 31 are correspondingly connected to the base 10 and the winding post 212 to drive the left clamping arm 21 to reset; the right clamping arm 22 has a right clamping portion 221 at the upper end and a winding post 222 at the lower end, and the right clamping arm 22 is rotatably mounted on the right side of the transverse portion 11 through the winding post 222, and a torsion spring 31 is also sleeved on the winding post 222 of the right clamping arm 22 (the torsion spring 31 is the above-mentioned elastic element 30), and the two ends of the torsion spring 31 are correspondingly connected to the base 10 and The winding post 222 is used to drive the right clamping arm 22 to reset; the bottom support arm 23 has a lower support part 231, and a accommodating groove 232 for accommodating the above-mentioned left clamping part 21 and the right clamping part 22 is arranged at the lower side of the lower support part 231, and a placement groove 233 for accommodating electronic products is arranged at the upper end of the lower support part 231, and a sliding column 234 is arranged at the rear end of the lower support part 231, and the sliding column 234 is correspondingly slidable up and down in the vertical slide groove 13 of the above-mentioned base 10; the bottom support arm 23 realizes vertical sliding on the base 10 through the cooperation of the sliding column 234 and the vertical slide groove 13; and a limiting plate 235 is arranged at the rear end of the sliding column 234, and the limiting plate 235 is slidably cooperated with the outer side wall of the vertical slide groove 13 to prevent the sliding column 234 from shaking back and forth in the vertical slide groove 13; in addition, a threading column 236 is also arranged on the rear side of the lower support part 231.

[0044] A pull rope 24 (in this embodiment, one pull rope 24) is connected between the left clamping arm 21 and the bottom support arm 23 and between the right clamping arm 22 and the bottom support arm 23. One end of the pull rope 24 is wound counterclockwise around the winding post 212 of the left clamping arm 21, and the other end is wound clockwise around the winding post 222 of the right clamping arm 22. The middle part of the pull rope 24 is connected to the threading post 236 of the bottom support arm 23. The middle part of the pull rope 24 can be fixedly connected to the threading post 236 or slidably connected to the threading post 236.

[0045] When the bracket is in the folded state, the left clamping portion 211 of the left clamping arm 21 and the right clamping portion 221 of the right clamping arm 22 are respectively driven by the restoring elastic force of the torsion spring 31 to rotate downward and be accommodated in the receiving groove 232 of the lower support portion 231 .

[0046] After the electronic product is placed on the bracket, the gravity of the electronic product causes the bottom support arm 23 to slide downward. Under the pulling of the pull rope 24, the bottom support arm 23 will drive the left clamping part 211 and the right clamping part 221 to flip out of the accommodating groove 232, and as the bottom support arm 23 slides down, they will rotate upward to clamp the electronic product.

[0047] As the second embodiment of the present invention, on the basis of the first embodiment (retaining the torsion spring 31), a tension spring 32 is connected between the upper end of the base 10 and the bottom support arm 23. The tension spring 32 is equivalent to the elastic element 30, so that the bracket can be reset more effectively under the joint action of the torsion spring 31 and the tension spring 32, and the folding is faster and more convenient. It should be noted that the difference between the second embodiment and the first embodiment is only the addition of the tension spring 32, so both are attached. Figure 1-4 Show the specific structure.

[0048] As a third embodiment of the present invention, as shown in the attached Figure 5-8 As shown, the base 10 is in a transverse plate shape, and the left clamping arm 21 and the right clamping arm 22 are rotatably mounted on the left and right sides of the base 10, respectively. The left clamping arm 21 has a left connecting column 213 at the lower end, and a left gear 214 is integrally arranged on the left connecting column 213. The left clamping arm 21 is rotatably mounted on the base 10 through the left connecting column 213; the right clamping arm 22 has a right connecting column 223 at the lower end, and a right gear 224 is integrally arranged on the right connecting column 223. The right clamping arm 22 is rotatably mounted on the base 10 through the right connecting column 223; and a driving gear 14 is rotatably mounted on the left and right sides of the base 10 respectively. The two driving gears 14 are located between the left gear 214 and the right gear 224 (the space between the left gear 214 and the right gear 224 can be effectively utilized to reduce the width of the bracket), and the left driving gear 14 is meshed with the left gear 214, and the right driving gear 14 is meshed with the right gear 224; and a hook column 15 is vertically arranged on the end surface of the two driving gears 14, and a horizontal slide groove 237 is arranged on the bottom support arm 23, and the hook columns 15 of the two driving gears 14 can be horizontally moved in the horizontal slide groove 237; the elastic element 30 is two torsion springs, and the two torsion springs are respectively connected between the two driving gears 14 and the base 10. The bottom support arm 23 is provided with a receiving groove 232 that is the same as the above two embodiments.

[0049] In the third embodiment, when the bracket is folded, the driving gears 14 on both sides rotate under the drive of their respective torsion springs 31, linking the left gear 214 and the right gear 224 to rotate, thereby rotating the left clamping part 211 and the right clamping part 221 to be accommodated in the accommodating groove 232.

[0050] After the electronic product is placed on the bracket, the gravity of the electronic product drives the bottom support arm 23 to move downward, and the bottom support arm 23 drives the two driving gears 14 to rotate with the cooperation of the horizontal slide groove 237 and the hook column 15, and links the left gear 214 and the right gear 224 to rotate; the left clamping part 211 and the right clamping part 221 are respectively flipped outward to exit the accommodating groove 232, and as the bottom support arm 23 gradually slides down, they are respectively rotated upward to clamp the electronic product.

[0051] The design focus of the present invention is to form a gravity bracket by combining the left clamping arm, the right clamping arm, the bottom support arm and the elastic element on the base, and to set a receiving groove at the lower end of the bottom support arm, so that the left and right clamping parts can be stored in the receiving groove when the bracket is folded, thereby reducing the overall volume of the bracket in the folded state, reducing the space occupied by the bracket, reducing the blocking area of ​​the car air outlet, and making the air outlet air flow smoother; and after folding, the volume is small and easy to carry.

[0052] The above description is only a preferred embodiment of the present invention and does not limit the technical scope of the present invention. Therefore, any slight modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
