[0027] The creation of the present utility model will be described in detail below with reference to the drawings and in combination with embodiments.
[0028] As Figure 1 、 Figure 2 shown, a camera flipping device provided by an embodiment of the present utility model includes: a base 1, a driving mechanism 2, and a locking mechanism 3; the base 1 is the base of the entire mechanism, the camera 4 is fixed on the base 1, and the base 1 is located between the driving mechanism 2 and the locking mechanism 3; the locking mechanism 3 has two states: locked and open. The initial state of the locking mechanism 3 is the locked state. When the camera rotates, the locking mechanism 3 opens, and the driving mechanism 3 drives the base 1 to drive the camera to flip. The driving mechanism 2 drives the base 1 to rotate by an angle of 0 - 180°.
[0029] As Figure 3 shown, a groove 11 is provided on one side of the base 1 connected to the driving mechanism 2, and a lock catch 12 is provided on the other side of the base 1; the lock catch 12 includes a flat plate portion 121 and an arc portion 122. The flat plate portion 121 is connected to the base 1, and the shape of the arc portion 12 is adapted to the arc shape of the locking piece 32.
[0030] As Figure 4 、 Figure 5As shown in the figure, the driving mechanism 2 includes two first fixing seats 21, a driving piece 22 and a first heating sheet 23; the two first fixing seats 21 are arranged at intervals and connected to one end of the driving piece 22, and the other end of the driving piece 22 is inserted into the groove 11 and fixed by bolts; the first heating sheet 23 is arranged on the upper surface of the driving piece 22; the first fixing seat 21 includes a first fixing plate 211 and an L-shaped connecting plate 212, the first fixing seat 21 is rectangular, the long side of the L-shaped connecting plate 212 is vertically arranged on the upper surface of the fixing plate 211 and is located in the middle position of the first fixing seat 21. An opening 213 adapted to the driving piece 22 is provided on the side of the short side of the L-shaped connecting plate 212 facing the driving piece 22, and the driving piece 22 is inserted into the opening 213 and fixed to the L-shaped connecting plate 212 by bolts. The driving piece 22 is made of a shape memory polymer composite material, the initial state of the driving piece 22 is flat, and the working state of the driving piece 22 is arc-shaped. When the first heating sheet 23 is heated, the driving piece 22 gradually bends into an arc shape.
[0031] Shape memory polymer composite materials refer to composite materials formed by combining shape memory polymers with one or more reinforcing materials (such as carbon fiber, glass fiber, metal particles, etc.). Shape memory polymer composite materials can recover their original shape through external stimuli after deformation, and have high specific strength and specific stiffness. Shape recovery can be achieved through different driving methods (heat, electricity, light, magnetism, etc.), and some materials also have characteristics such as self-repair and self-sensing.
[0032] As Figure 6 , Figure 7 As shown in the figure, the locking mechanism 3 includes a second fixing seat 31, a locking piece 32 and a second heating sheet 33. One end of the locking piece 32 is connected to the second fixing seat 31, and the other end of the locking piece 32 is a free end; the second heating sheet 33 is arranged on the upper surface of the locking piece 32. The second fixing seat 31 includes a second fixing plate 311 and two clamping plates 312 vertically arranged on the second fixing plate. The two clamping plates 312 clamp the locking piece 32 by bolts. The locking piece 32 is made of a shape memory polymer composite material. The initial state of the free end of the locking piece 32 is arc-shaped. When the second heating sheet 33 is heated, the free end of the locking piece 32 gradually unfolds into a flat shape.
[0033] When the locking mechanism 3 is in the locked state, the free end of the locking piece 32 is placed on the lock catch 12; when the camera is flipped, the free end deforms to separate the locking piece 32 from the lock catch 12, and the driving mechanism 2 drives the base 1 to rotate and then drives the camera 4 to flip.
[0034] Further, when the locking mechanism 3 is in the locked state, the driving piece 22 is in a flat plate shape, and the free end of the locking piece 32 is in an arc shape and is lapped on the lock catch 12; when the camera is flipped, the second heating sheet 33 is heated, and the free end of the locking piece 32 gradually unfolds from an arc shape to a flat plate shape and is separated from the lock catch 12; at the same time, the first heating sheet 23 is heated to make the driving piece 22 gradually bend into an arc shape, thereby driving the base 11 to rotate.
[0035] In this embodiment, the driving piece 22 and the locking piece 32 can memorize and restore to their respective preset single-angle shapes under heating conditions.
[0036] In other embodiments, the driving piece 22 can memorize and restore to a preset multi-angle shape under heating conditions.
[0037] The deformation ability of the shape memory polymer composite material is not limited to a single direction or angle. By precisely controlling the conditions of external stimuli (such as temperature, electric field strength, light intensity, etc.) and the composition and structure of the material, precise control of the deformation direction and angle of the shape memory polymer composite material can be achieved. The shape memory polymer composite material can deform at multiple angles to meet different application requirements. By precisely controlling the heating and cooling processes, the shape change of the material at different temperatures can be achieved. Using temperature gradients or local heating techniques, different temperature distributions can be generated in different regions of the shape memory polymer composite material, thereby achieving multi-angle deformation.

[0039] The above specific embodiments do not constitute a limitation to the protection scope of the present invention. Those skilled in the art should understand that various modifications, combinations, sub-combinations, and substitutions can be made according to design requirements and other factors. Any modifications, equivalent substitutions, and improvements made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
