[0003] At present, the driving devices of existing bionic shark toys are generally arranged inside the shark body to drive several structural bodies to move. However, such an arrangement requires the separate setting of driving devices between several structures, which not only increases the manufacturing cost, but also makes it impossible to set up and display the shark body for viewing. Moreover, it is very difficult to control the driving amplitude and time difference between several driving devices, and it is easy to cause inconsistent driving, resulting in a rigid and lack of smoothness in the movement of the bionic shark body.
[0004] Designing a bionic shark toy device to solve the problems existing in the above-mentioned prior art is the purpose of the research of the utility model. Content of the Utility Model
[0005] In view of the problems existing in the above-mentioned prior art, the utility model provides a bionic shark toy device, which can effectively solve the problems existing in the above-mentioned prior art.

The driving shaft comprises several eccentric parts offset radially outwards. The swinging assembly comprises a swinging limiting member rotatably limited, and a swinging member connected to the swinging limiting member. One end of the swinging limiting member extends to form a swinging block sleeved on the corresponding eccentric part through a vertically extending vertical hole. The turnover assembly comprises a turnover limiting member rotatably limited, and a turnover member slidably penetrating through the turnover limiting member and one end of which is fitted on the corresponding eccentric part. The other ends of the swinging member and the turnover member are respectively connected to the corresponding movable blocks. When the driving shaft rotates, the swinging member is driven to swing through the cooperation of the corresponding eccentric part and the vertical hole to drive the corresponding movable block to swing, and the turnover member is driven to swing up and down through the corresponding eccentric part to drive the corresponding movable block to turnover.

The offset distance D3 of the tail fin swing part is greater than the offset distance D2 of the fish tail swing part is greater than the offset distance D1 of the fish head turnover part. When the fish head turnover part, the fish tail swing part, and the tail fin swing part rotate, the turnover movement of the shark head is driven by the swing up and down of the corresponding one turnover part, and the sequential swing movements of the shark tail fin part and the shark tail are driven by the swing of the two swing parts. Moreover, the swing movement amplitude of the shark tail fin part is greater than the swing movement amplitude of the shark tail is greater than the turnover movement amplitude of the shark head.

[0016] Furthermore, the far ends of the corresponding left and right limit plate groups extend downward to form a plurality of limit rib groups fixedly mounted on the left and right inner walls of the shell, each of the limit rib groups includes two limit ribs spaced apart front and back and forming a sliding groove therebetween, a plurality of reinforcing ribs are fixedly arranged between the two limit plates of the same group and between the limit plate groups and limit rib groups adjacent front and back, the drive shaft is laterally arranged front and back in the middle between the corresponding left and right limit rib groups, and the swing block swings left and right between the corresponding left and right sliding grooves.
[0017] Furthermore, a support block is provided in the shell and is sleeved on the outside of the drive shaft. One end of the support block abuts the limiting rib group on one side, and the front and rear protrusions on the other end form an inserting portion inserted between the adjacent limiting rib groups on the other side, and the inserting portion is limitedly inserted between the upper and lower adjacent reinforcing ribs. The top recess of the support block is provided with an installation groove which extends downward and then folds horizontally to extend to the middle of the support block to form a cylindrical rotating hole. Both sides of the installation groove pass through the front and rear sides of the support block, and the drive shaft is installed in the rotating hole through the installation groove and is rotatably arranged.
[0018] Therefore, the utility model provides the following effects and / or advantages:
[0019] 1. By designing the drive shaft to include a number of eccentric parts that are radially offset outward, the rocking assembly and the turnover assembly are driven. When the drive shaft rotates under power, the corresponding eccentric parts cooperate with the vertical holes to drive the rocker to rock, thereby driving the corresponding movable block to rock, and the corresponding eccentric parts drive the turnover part to rock up and down to drive the corresponding movable block to turn. Thus, while the drive shaft can support the shark body through the rocking assembly and the turnover assembly for display, the activity differences of the rocking assembly and the turnover assembly can be adjusted through the eccentric parts to adjust the movement amplitude and movement time difference of several movable blocks to simulate the coherent head and tail swinging actions of the shark, thereby improving the fluency and coordination of the actions presented by the shark body driven by the rocking assembly and the turnover assembly. The bionic actions of the shark body are vivid and highly simulated, greatly improving the ornamental value of the bionic shark toy device.
[0020] 2. On the basis that one end of the turnover part is properly sleeved on the corresponding eccentric part, through the close fit between the vertical hole and the corresponding eccentric part, the effect that the offset distance of the eccentric part is used to adjust the movement amplitude of the movable block and the included angle between the eccentric parts is used to adjust the movement time difference between several movable blocks is stably achieved. Thus, the drive shaft can drive the rocking assembly and the turnover assembly through a number of eccentric parts to drive the shark body to simulate the action details of the corresponding animal swimming or walking, improving the simulation effect.
[0021] 3. The shark head includes a head body that is rotatably connected to the left and right of the shark abdomen, and a lower jaw part that is rotatably connected to the upper and lower of the head body at the rear end. The upper end of the turnover part is rotatably connected to the lower jaw part. Thus, when the turnover part rocks up and down, it drives the lower jaw part to swing up and down and open and close, while driving the head body to turn, so as to realize that the shark head can simulate the mouth opening and closing action and the head swinging action when the shark swims, further enriching the movement details of the shark body swimming and improving the simulation effect of the driving base driving the shark body to simulate the swimming action of the shark.
[0022] 4. When the fish head turnover part, the fish tail swing part, and the caudal fin swing part rotate, the corresponding turnover part swings up and down to drive the turnover of the shark's head, presenting a head-swinging swimming motion; by setting the offset distance, offset direction, and the included angle between the fish tail swing part and the caudal fin swing part, there is a certain swing time difference between the shark's tail and the caudal fin. While the shark's head rotates slightly and the lower jaw swings up and down, the shark's tail and caudal fin have a visual effect of swinging left and right in sequence, and the swing amplitude gradually increases from the shark's tail to the caudal fin, making the caudal fin and the shark's tail swing in sequence to present a smooth tail-swinging swimming motion, and the swing amplitude of the caudal fin is greater than that of the shark's tail, which is greater than the turnover amplitude of the shark's head; the turnover of the shark's head is synchronized with the swing of the caudal fin, so that the shark body presents a visual effect of the shark's head and tail swinging to drive the whole body forward. It improves the fluency, coordination, and simulation effect of the shark body's head-swinging and tail-swinging forward swimming motion, and can be cycled, greatly improving the ornamental value of the bionic shark toy device.
[0023] 5. Through the front-back and left-right limiting of the swing limiting part and the turnover limiting part by the limiting area, while the housing limits the swing limiting part and the turnover limiting part in the left-right swing direction, it avoids the front-back displacement during the left-right swing, so that the swing limiting part and the turnover limiting part can stably drive the swing part and the turnover part to perform left-right swing actions and lift-swing actions, improving the stability of the swing assembly and the turnover assembly, and further improving the stability when driving the corresponding movable block to move, and improving the overall stability of the bionic shark toy device.

[0032] For the convenience of those skilled in the art to understand, the embodiments will be further described in detail with reference to the accompanying drawings for the structure of the present utility model:
[0033] Refer to Figure 1-7 , a bionic shark toy device, comprising:
[0034] A shark body 2, including a plurality of movably connected movable blocks;
[0035] A drive base, including a drive shaft 11 driven to rotate by power, as well as a swing assembly 3 and a turnover assembly 4. The drive shaft 11 includes a plurality of eccentric parts 13 offset radially outward. The swing assembly 3 includes a swing limiting member 31 rotatably limited, and a swing member 32 connected to the swing limiting member 31. One end of the swing limiting member 31 extends to form a swing block 311 sleeved on the corresponding eccentric part 13 through a vertically extending vertical hole 312. The turnover assembly 4 includes a turnover limiting member 41 rotatably limited, and a turnover member 42 slidably passing through the turnover limiting member 41 and one end of which is adaptively sleeved on the corresponding eccentric part 13. The other ends of the swing member 32 and the turnover member 42 are respectively connected to the corresponding movable blocks. When the drive shaft 11 rotates, the swing member 32 is driven to swing through the cooperation of the corresponding eccentric part 13 and the vertical hole 312 to drive the corresponding movable block to swing, and the turnover member 42 is driven to swing up and down through the corresponding eccentric part 13 to drive the corresponding movable block to turnover. Specifically, a handle can be externally added to the end of the drive shaft 11 for manual rotation, or the drive shaft 11 can be driven to rotate by arranging a power device 12 in the drive base. The power device 12 can be a rotating motor, etc. A circuit board electrically connected to the power device 12 is provided in the drive base. Atmosphere lights for projecting lights onto the shark body 2 are respectively provided at the front and rear tops of the drive base, and control buttons are provided on the side walls. The atmosphere lights and the control buttons are respectively electrically connected to the circuit board;
[0036] With the above structure, while the drive shaft 11 can hold up the shark body 2 through the swing assembly 3 and the epicyclic assembly 4 for display, the activity difference between the swing assembly 3 and the epicyclic assembly 4 can also be adjusted through the eccentric part 13 to adjust the movement amplitude and movement time difference of several movable blocks, so as to simulate the coherent head and tail swinging and other actions of the shark, thereby improving the smoothness and coordination of the actions presented by the shark body 2 driven by the swing assembly 3 and the epicyclic assembly 4. The bionic actions of the shark body 2 are vivid and highly simulated, greatly improving the ornamental value of the bionic shark toy device.
[0037] In order to stably realize the adjustment of the movement amplitude and movement time difference of several movable blocks through the eccentric part 13, the width of the vertical hole 312 is adapted to the diameter of the corresponding eccentric part 13. The offset distance of several eccentric parts 13 is used to adjust the movement amplitude of several movable blocks, and the included angle between several eccentric parts 13 is used to adjust the movement time difference between several movable blocks. On the basis that one end of the epicyclic part 42 is properly sleeved on the corresponding eccentric part 13, through the tight fit between the vertical hole 312 and the corresponding eccentric part 13, the effect that the offset distance of the eccentric part 13 is used to adjust the movement amplitude of the movable block and the included angle between the eccentric parts 13 is used to adjust the movement time difference between several movable blocks can be stably realized, so that the drive shaft 11 can drive the swing assembly 3 and the epicyclic assembly 4 through several eccentric parts 13 to drive the shark body to simulate the action details of corresponding animals swimming or walking, improving the simulation effect. For example, the tail can swing in large and small amplitudes and with a certain time difference in segments, so that the tail action shows a swinging effect with the amplitude decreasing successively, and the bionic action is more vivid and smooth.
[0038] Specifically, the plurality of movable blocks include a shark head 21, a shark abdomen 22, a shark tail 23, and a shark tail fin 24 that are movably connected in sequence. The shark head 21 is rotatably connected to the shark abdomen 22, and the shark abdomen 22, the shark tail 23, and the shark tail fin 24 are rotatably connected to each other in sequence. The shark head 21, the shark abdomen 22, the shark tail 23, and the shark tail fin 24 are respectively assembled by a plurality of corresponding blocks, thereby increasing the assembly function of the bionic shark toy device and improving the fun. The plurality of eccentric portions 13 are fish head turnover portions 131, fish tail swing portions 132 that are distributed in sequence at intervals. , tail fin swinging part 133, the number of the turnover components 4 is set to one group, the number of the swing components 3 is set to two groups, the driving base also includes an abdomen supporting component 5 for supporting the shark abdomen 22, the lower end of the turnover part 42 of the turnover component 4 is adapted to be mounted on the fish head turnover part 131, and the upper end is rotatably connected to the shark head 21, the two groups of swing blocks 311 of the swing components 3 are respectively mounted on the fish tail swinging part 132 and the tail fin swinging part 133 through vertical holes 312, and the upper ends of the swing parts 32 of the two groups of the swing components 3 are rotatably connected to the shark tail 23 and the shark tail fin 24. Therefore, when the fish head rotating part 131, the fish tail swinging part 132, and the tail fin swinging part 133 rotate, the shark head 21 is driven to rotate by the upper end of the corresponding rotating part 42, and the two swinging parts 32 swing to drive the shark tail fin 24 and the shark tail 23 to swing left and right, so as to realize the simulation effect of the shark body 2 swinging its body left and right and swimming forward.
[0039] In order to further improve the simulation action effect of the shark body 2, the shark head 21 includes a head body 211 that is connected to the shark abdomen 22 for rotation, a lower jaw 212 that is connected to the head body 211 for rotation up and down at the rear end, and the upper end of the turnover member 42 is connected to the lower jaw 212 for rotation. The head body 211 is connected to the shark abdomen 22 for rotation left and right through a plurality of ear plates and perforations, and the width of the perforations is greater than the width of the ear plates, so that there is a gap between the connection between the ear plates and the perforations to meet the needs of the turnover action. The upper end of the turnover member 42 is connected to the lower jaw 212 for rotation, so that when the turnover member 42 is lifted and swung, the lower jaw 212 is driven to swing up and down and open and close, and the head body 211 is driven to rotate, so that the shark head 21 can simulate the mouth opening and closing action and the head swinging action when the shark swims, further enriching the details of the swimming action of the shark body 2, and improving the simulation effect of the driving base driving the shark body 2 to simulate the swimming action of the shark.
[0040] In order to improve the fluency of the forward swimming action of the shark body 2 while swinging its head and wagging its tail left and right, the fish head turnover part 131 and the tail fin swaying part 133 are offset towards the same side. The tail fin swaying part 133 and the fish tail swaying part 132 are sequentially distributed along the rotation direction of the drive shaft 11, and the included angle A1 between them is an acute angle. The offset distance D3 of the tail fin swaying part 133 is greater than the offset distance D2 of the fish tail swaying part 132 which is greater than the offset distance D1 of the fish head turnover part 131; the included angle A1 is 40° - 50°, and the offset distances D1, D2, and D3 are 4mm - 6mm, 7mm - 9mm, and 11mm - 13mm respectively. Specifically, the fish head turnover part 131, the fish tail swaying part 132, and the tail fin swaying part 133 are offset upwards, towards the upper right side, and upwards respectively. In this embodiment, the offset distances D1, D2, and D3 are 5mm, 8mm, and 12.5mm respectively, and the included angle A1 is 45°; thus, when the fish head turnover part 131, the fish tail swaying part 132, and the tail fin swaying part 133 rotate, the corresponding one of the turnover parts 42 swings up and down to drive the turnover of the shark head 21 to present a head-swinging swimming action; through the settings of the offset distances, offset directions, and the included angle between the fish tail swaying part 132 and the tail fin swaying part 133, there is a certain swing time difference between the shark tail 23 and the shark tail fin part 24. While the shark head 21 rotates slightly and the lower jaw part 212 swings up and down to open and close, the shark tail 23 and the shark tail fin part 24 have a visual effect of swinging left and right in sequence, and the swing movement amplitude gradually increases from the shark tail 23 to the shark tail fin part 24, enabling the shark tail fin part 24 and the shark tail 23 to swing in sequence to present a smooth tail-wagging swimming action, and the swing movement amplitude of the shark tail fin part 24 is greater than the swing movement amplitude of the shark tail 23 which is greater than the turnover movement amplitude of the shark head 21; the turnover of the shark head 21 and the swing of the shark tail fin part 24 are synchronized, so that the shark body 2 presents a visual effect of the shark head 21 and the shark tail 23 swinging and exerting force to drive the whole body forward. The fluency, coordination, and simulation effect of the forward swimming action of the shark body 2 while swinging its head and wagging its tail left and right are improved, and it can be carried out cyclically, greatly improving the ornamental value of the bionic shark toy device.
[0041] Furthermore, the fish head rotating part 131 and the fish tail swinging part 132 are connected by a non-offset self-rotating part 134, and the abdomen supporting assembly 5 includes an abdomen limiting member 51 with a limited rotation setting and the same structure as the swing limiting member 31, and an abdomen supporting member 52 that passes through the abdomen limiting member 51 from top to bottom and the lower end of which is sleeved on the self-rotating part 134, and the upper end of the abdomen supporting member 52 is connected to the shark abdomen 22. Therefore, through the rotatable characteristics of the abdomen limiting member 51, when the shark head 21 rotates and the shark tail 23 swings left and right, the shark abdomen 22 can be adaptively swung left and right with a small amplitude after being stressed, further improving the smoothness of the shark body 2 swinging the body left and right to swim forward.
[0042] In order to improve the stability of the bionic shark toy device when it is started, the driving base also includes a shell 1, and a plurality of left and right extending clearance holes 14 are penetrated on the top of the shell 1, and the other ends of the swing member 32 and the turnover member 42 penetrate the corresponding clearance holes 14 and are connected to the corresponding movable blocks, and the left and right inner walls of the shell 1 are respectively protruded with a plurality of limit plate groups 15 facing each other, and the plurality of limit plate groups 15 on the same side are arranged at intervals in front and back, and each of the limit plate groups 15 includes two limit plates 151 arranged at intervals in front and back and forming a limit area 152 therebetween, and the ends of the left and right corresponding limit plates 151 are oppositely arc-shaped recessed to form a limit groove 153, and the swing limit member 31 and the turnover limit member 41 are respectively rotatably arranged between the left and right corresponding limit grooves 153, and the outer walls of the swing limit member 31 and the turnover limit member 41 are respectively arc-shaped protruded to form a swing limit portion 313 and a turnover limit portion 411 which are limitedly rotatably arranged in the left and right corresponding limit areas 152. Specifically, the swing limit member 31 and the turnover limit member 41 are both configured to be columnar in shape, the diameter of which matches the inner diameter of the two corresponding limit grooves 153, and the swing limit portion 313 and the turnover limit portion 411 are respectively located at the bottom middle of the swing limit member 31 and the turnover limit member 41 and extend upward toward the left and right sides to a position not lower than the middle of the swing limit member 31 and the turnover limit member 41. Thus, by limiting the front and rear and left and right positions of the swing limiting part 313 and the turnover limiting part 411 through the limiting area 152, the shell 1 limits the swing limiting member 31 and the turnover limiting member 41 in the left and right swinging direction, while avoiding the front and rear displacement during the left and right swinging process, so that the swing limiting member 31 and the turnover limiting member 41 can stably drive the swing member 32 and the turnover member 42 to swing left and right and to lift and swing, thereby improving the stability of the swing assembly 3 and the turnover assembly 4, thereby improving the stability of the corresponding movable blocks when driving them to move, and improving the overall stability of the bionic shark toy device.
[0043] In order to further improve the stability of the bionic shark toy device, the far ends of several corresponding left and right limiting plate groups 15 extend downward to form several limiting rib groups 16 fixedly arranged on the left and right inner side walls of the housing 1. Each limiting rib group 16 includes two limiting ribs 161 arranged at intervals front and back with a sliding groove 162 formed therebetween. A number of reinforcing ribs 19 are fixedly arranged between two limiting plates 151 in the same group, and between the adjacent front and back limiting plate groups 15 and limiting rib groups 16. The driving shaft 11 is horizontally arranged front and back in the middle between several corresponding left and right limiting rib groups 16, and the swing block 311 swings left and right between the corresponding left and right sliding grooves 162. Thus, the left and right swing of the swing block 311 is limited by the sliding groove 162, improving the stability of the left and right swing of the swing member 32, and further improving the overall stability of the bionic shark toy device. Moreover, the structural strength of several limiting plate groups 15 and several limiting rib groups 16 is improved by the arrangement of a number of reinforcing ribs 19, reducing the risk of the limiting plate groups 15 and limiting rib groups 16 being bent under pressure.
[0044] In order to improve the stability of the driving shaft 11, a support block 18 sleeved on the outer side of the driving shaft 11 is arranged in the housing 1. One end of the support block 18 abuts against one side of the limiting rib group 16, and the front and back sides of the other end protrude to form a plug-in part 181 inserted between the adjacent limiting rib groups 16 on the other side. And the plug-in part 181 is limited and inserted between the adjacent upper and lower reinforcing ribs 19. A concave installation groove 182 is provided at the top of the support block 18, which extends downward and then laterally folds to extend to the middle of the support block 18 to form a cylindrical rotation hole 183. The two sides of the installation groove 182 penetrate through the front and back sides of the support block 18, and the driving shaft 11 is installed in the rotation hole 183 through the installation groove 182 for rotation setting. Thus, the structural strength and driving stability of the driving shaft 11 are improved by the auxiliary support of the support block 18, and the force of the driving shaft 11 is sequentially transmitted to the reinforcing rib 19, the limiting rib group 16 and the housing 1 through the support block 18, thereby dispersing stress and reducing the risk of the driving shaft 11 being bent by the pulling of each component at different positions during driving.
[0045] Since in this embodiment, the driving shaft 11 is only supported at the front and rear ends by the power device 12 and the fixing block 17, and the volumes and weights of several of the assembled blocks of the shark head 21 and the shark abdomen 22 are greater than those of several of the assembled blocks of the shark tail 23 and the shark tail fin part 24, therefore, preferably, the number of the support blocks 18 is set to one and is located between the abdominal support member 52 and the fish head turnover part 131. Thus, on the premise of controlling costs and the weight of the toy, the front half of the driving shaft 11 is assisted in support by the support block 18 to improve the structural strength and driving stability of the front half of the driving shaft 11, and at the same time reduce the influence of the swing of the fish head turnover part 131 on the rotation part 134.

For those skilled in the art, the present utility model may have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
