Description

Technical Field

[0001] The invention relates to a bionic fish, in particular to a bionic fish with more than two shells. Background Art

[0002] In order to meet the movement requirements of bionic fish, bionic fish usually include multiple movable joints, which are often made of hard materials (such as plastic or metal). In order to avoid the interference between the movable joints after rotation or movement, it is necessary to make an avoidance design on the structure of the connection. However, the avoidance design easily causes the appearance of the bionic fish to have steps, gaps, depressions or unevenness, which is particularly obvious in the bending state during movement, making the appearance of the bionic fish appear less natural. Summary of the invention

[0003] An object of the present invention is to provide a bionic fish that can improve at least one problem in the background art.

[0004] In some embodiments, the bionic fish of the present invention includes a shell. The shell includes two shells arranged in sequence along the front-to-back direction, and a covering structure formed at the junction of the two shells, the two shells can be connected to each other rotatably around a rotation axis, and the rotation axis is parallel to the up-down direction, the covering structure includes a first covering portion formed on one of the two shells, and a second covering portion formed on the other of the two shells, the first covering portion has two terminal side edges located at the end and arranged along the left-right direction, the second covering portion has two arc-shaped outer side surfaces arranged along the left-right direction and corresponding to the two terminal side edges respectively, and the curvature center of the two arc-shaped outer side surfaces is located on the rotation axis. Wherein, at least one of the arc-shaped outer side surfaces is adjacent to the corresponding terminal side edge, and the portion of the arc-shaped outer side surface adjacent to the terminal side edge is located on the inner side of the terminal side edge.

[0005] In some embodiments, the first covering portion further has two arcuate inner side surfaces respectively connected to the two end side edges and arranged along the left-right direction, and the two arcuate inner side surfaces are respectively used to face inwardly toward the two arcuate outer side surfaces of the second covering portion, and are respectively used to correspond to the two arcuate outer side surfaces.

[0006] In some embodiments, the first covering portion is formed at the rear end of the former of the two shells, and the second covering portion is formed at the front end of the latter of the two shells, and the two arc-shaped outer side surfaces of the second covering portion are located in front of the rotation axis in the front-to-back direction.

[0007] In some implementations, the housing includes a plurality of shells, and a plurality of covering structures each formed at a junction between two adjacent shells.

[0008] In some implementations, the bionic fish further includes a rotating mechanism disposed between the two shells and connecting the two shells so as to be rotatable relative to each other around the rotating axis.

[0009] In some implementations, the rotating mechanism includes a fixed portion disposed in the former of the two shells, and a rotating portion disposed in the latter of the two shells, and the rotating portion is rotatably connected to the fixed portion around the rotation axis.

[0010] In some embodiments, the outer shell can be converted between an initial state and a bent state through relative rotation between the two shells. In the initial state, the two arcuate outer surfaces are respectively adjacent to the two terminal side edges, and the portions of the two arcuate outer surfaces respectively adjacent to the two terminal side edges are located on the inner sides of the two terminal side edges; in the bent state, the arcuate outer surface on the side of the outer shell that bulges outward due to bending is adjacent to the corresponding terminal side edge, and the portions of the arcuate outer surface adjacent to the terminal side edge are located on the inner sides of the terminal side edges.

[0011] In some embodiments, the shell passes through a transition state when switching between the initial state and the bent state. In the transition state, the two arcuate outer surfaces are respectively adjacent to the two terminal side edges, and the portions of the two arcuate outer surfaces respectively adjacent to the two terminal side edges are located on the inner sides of the two terminal side edges.

[0012] The beneficial effect of the present invention is that the arc-shaped outer side surface of the second covering part and the end side edge of the first covering part adjacent to each other make the step difference, gap and depression at the connection between the two shells of the shell less obvious. And the arc-shaped appearance of the two arc-shaped outer side surfaces of the second covering part reduces the unevenness at the connection between the two shells of the shell. Since the step difference, gap, depression or unevenness are less likely to occur and less obvious, the appearance of the bionic fish can be made more natural. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] See also Figures 1 to 4 An embodiment of the bionic fish 100 of the present invention comprises a housing 1 and a plurality of rotating mechanisms 2 disposed in the housing 1. The housing 1 is generally mirror-symmetrical along a left-right direction D1, and can be made of materials such as plastic or metal. The housing 1 comprises a plurality of shells 11 arranged in sequence along a front-to-back direction D2, and a plurality of covering structures 12 each formed at the junction of two adjacent shells 11. A rotating mechanism 2 is disposed between each two adjacent shells 11, and the rotating mechanism 2 enables the two shells 11 to be connected to each other rotatably around a rotation axis A, and the rotation axis A is parallel to an up-down direction D3. The rotating mechanism 2 comprises a fixed portion 21 disposed in the former of the two shells 11, and a rotating portion 22 disposed in the latter of the two shells 11, and the rotating portion 22 can be rotatably connected to the fixed portion 21 around the rotation axis A. The rotating portion 22 can be driven by an electronic component such as a motor (not shown) to rotate relative to the fixed portion 21.

[0025] Each of the cover structures 12 includes a first cover portion 121 formed at the rear end of the former of each of the two adjacent shells 11, and a second cover portion 122 formed at the front end of the latter of the two shells 11. The first cover portion 121 has two terminal side edges 121a located at the end and arranged along the left-right direction D1, and two arc-shaped inner side surfaces 121b respectively connected to the two terminal side edges 121a and arranged along the left-right direction D1, and the two arc-shaped inner side surfaces 121b extend forward and inward from the two terminal side edges 121a respectively. The second cover portion 122 has two arc-shaped outer side surfaces 122a arranged along the left-right direction D1 and corresponding to the two terminal side edges 121a respectively, and the two arc-shaped outer side surfaces 122a are located in front of the rotation axis A in the front-back direction D2, and the curvature centers of the two arc-shaped outer side surfaces 122a are located on the rotation axis A. The two arc-shaped inner side surfaces 121b are respectively used to face inwardly toward the two arc-shaped outer side surfaces 122a of the second cover portion 122, and are respectively used to correspond to the two arc-shaped outer side surfaces 122a. It should be noted that in other embodiments, the first cover portion 121 can also be formed at the front end of the latter of the two shells 11, and the second cover portion 122 is formed at the rear end of the former of the two shells 11.

[0026] By the relative rotation between the two adjacent shells 11, the housing 1 can be in an initial state and a bent state (see Figure 8 ), and when switching between the initial state and the bent state, a transition state (see Figure 5 It should be noted that the housing 1 can be bent toward both sides along the left-right direction D1. To simplify the description, only the operation state of the housing 1 bending toward one side is described here.

[0027] In the initial state, the shell 1 extends roughly straight along the front-to-back direction D2, and the two arc-shaped outer side surfaces 122a between each two adjacent shells 11 are respectively adjacent to the two terminal side edges 121a, and the parts of the two arc-shaped outer side surfaces 122a respectively adjacent to the two terminal side edges 121a are located on the inner sides of the two terminal side edges 121a.

[0028] See also Figures 5 to 7 In the transition state, although the shell 1 is slightly curved, the two arc-shaped outer sides 122a are still respectively adjacent to the two terminal side edges 121a, and the parts of the two arc-shaped outer sides 122a respectively adjacent to the two terminal side edges 121a are located on the inner sides of the two terminal side edges 121a.

[0029] See also Figures 8 to 10 In the bending state, the housing 1 is bent to the limit, and the arc-shaped outer side surface 122a on the side of the housing 1 that is convex due to bending is still adjacent to the corresponding terminal side edge 121a, and the part of the arc-shaped outer side surface 122a adjacent to the terminal side edge 121a is located on the inner side of the terminal side edge 121a. The other side that is concave due to bending is adjacent to the corresponding terminal side edge 121a from the inner side by the side surface of the latter of the two adjacent housings 11.

[0030] In summary, the present invention makes the step difference, gap and depression at the connection between the two shells 11 of the housing 1 less obvious through the arc-shaped outer side surface 122a of the second cover part 122 and the end side edge 121a of the first cover part 121. And the arc-shaped appearance of the two arc-shaped outer side surfaces 122a of the second cover part 122 reduces the unevenness at the connection between the two shells 11 of the housing 1. Since the step difference, gap, depression or unevenness is less likely to occur and less obvious, the appearance of the bionic fish 100 can be made more natural.

[0031] The above are merely embodiments of the present invention and should not be used to limit the scope of the present invention. That is, any simple equivalent changes and modifications made according to the claims and description of the present invention still fall within the scope of the present invention.
