Description

Technical Field

[0001] The utility model relates to the field of film and television shooting, in particular to a device for simulating the moving state of a quadruped. Background Art

[0002] Existing film and television dramas involve a large number of scenes where actors ride on four-legged animals such as horses and tigers. Due to safety and cost considerations, the above-mentioned shooting scenes rarely use actual four-legged animals. Instead, simulated leather covers of the four-legged animals are placed on a four-legged animal movement state simulation device, and the movement of the simulated leather covers is driven by the movement of the four-legged animal movement state simulation device for shooting.

[0003] The existing four-legged beast movement state simulation device is not only complex in structure, high in cost, and has a high failure rate, but also can only simulate a small number of four-legged beast movement states, making it difficult to meet the scene requirements of many filming scripts, and has a limited scope of application.

[0054] Example:

[0055] See also Figure 1-Figure 3 The present embodiment provides a quadruped movement state simulation device, including a bracket 1, a first telescopic rod 2, a second telescopic rod 3, a first connecting rod 4, a second connecting rod 5, a third connecting rod 6, a fourth connecting rod 7, a fifth connecting rod 8, a ninth connecting rod 9 and a saddle 20.

[0056] See also Figure 4-Figure 6 The bracket 1 is provided with a first rotation fulcrum 11, a second rotation fulcrum 12, a third rotation fulcrum 13 and a fourth rotation fulcrum 14. The distance between the first rotation fulcrum 11 and the third rotation fulcrum 13 is L4, and the distance between the fourth rotation fulcrum 14 and the second rotation fulcrum 12 is L5. In this embodiment, L4=L5. The first rotation fulcrum 11 and the second rotation fulcrum 12 are both located at the lower end of the bracket 1 and are spaced apart, and the third rotation fulcrum 13 and the fourth rotation fulcrum 14 are both located at the upper end of the bracket 1 and are spaced apart.

[0057] The first connecting rod 4 is provided with a fifth rotation fulcrum 41 and a sixth rotation fulcrum 42 at both ends, the first telescopic rod 2 is rotationally connected to the fifth rotation fulcrum 41 and the first rotation fulcrum 11 at both ends, and the second connecting rod 5 is rotationally connected to the third rotation fulcrum 13 and the sixth rotation fulcrum 42 at both ends. Thus, the first connecting rod 4, the second connecting rod 5, the bracket 1 and the first telescopic rod 2 form a four-bar linkage. The distance between the fifth rotation fulcrum 41 and the sixth rotation fulcrum 42 is L2, the distance between the sixth rotation fulcrum 42 and the third rotation fulcrum 13 is L3, L2, L3 and L4 are all fixed values, the length of the first telescopic rod 2 is L1, and the first telescopic rod 2 is extended to make the length of L1 variable, thereby the sixth rotation fulcrum 42 can be controlled to move by the first telescopic rod 2.

[0058] The third connecting rod 6 includes a first connecting section 62 and a second connecting section 63, one end of the first connecting section 62 and one end of the second connecting section 63 are fixedly connected, the first connecting section 62 and the second connecting section 63 are not coaxially arranged, and the angle between the first connecting section 62 and the second connecting section 63 is 100°-120°, and the angle is 110° in this year. The end of the first connecting section 62 away from the second connecting section 63 is rotatably connected to the fourth rotating fulcrum 14. The first connecting section 62 is provided with a ninth rotating fulcrum 61, and the distance between the ninth rotating fulcrum 61 and the fourth rotating fulcrum 14 is L6. The two ends of the second telescopic rod 3 are respectively rotatably arranged at the second rotating fulcrum 12 and the ninth rotating fulcrum 61. Thus, the bracket 1, the third connecting rod 6 and the second telescopic rod 3 form a three-link mechanism, wherein L5 and L6 are both fixed values, the length of the second telescopic rod 3 is L7, and the second telescopic rod 3 makes the length of L7 variable by telescoping, thereby the rotation of the third connecting rod 6 can be controlled by the second telescopic rod 3.

[0059] The fifth connecting rod 8 is provided with a seventh rotation fulcrum 81 and an eighth rotation fulcrum 82 at both ends, the fourth connecting rod 7 is rotatably connected to the sixth rotation fulcrum 42 and the seventh rotation fulcrum 81 at both ends, and the end of the second connecting section 63 away from the first connecting section 62 is rotatably connected to the eighth rotation fulcrum 82. Thus, the second connecting rod 5, the third connecting rod 6, the fourth connecting rod 7 and the fifth connecting rod 8 also form a four-bar linkage, and the first telescopic rod 2 and the second telescopic rod 3 can be extended and retracted in coordination to control the movement of the fifth connecting rod 8, especially to make the seventh rotation fulcrum 81 and the eighth rotation fulcrum 82 move in coordination.

[0060] One end of the ninth connecting rod 9 is fixed to the end of the fifth connecting rod 8 away from the seventh rotation fulcrum 81, the ninth connecting rod 9 is spaced apart from the eighth rotation fulcrum 82, the ninth connecting rod 9 is located on the side of the fifth connecting rod 8 away from the seventh rotation fulcrum 81, and the ninth connecting rod 9 is inclined toward the side of the fifth connecting rod 8 away from the bracket 1.

[0061] A four-legged animal leather case, such as a cow leather case, a horse leather case, etc., can be sleeved on the fifth connecting rod 8, so that the third connecting rod 6, the fourth connecting rod 7 and the fifth connecting rod 8 are located in the four-legged animal leather case, wherein the fifth connecting rod 8 supports the back of the four-legged animal leather case as the spine of the four-legged animal, and the ninth connecting rod 9 supports the head of the four-legged animal leather case as the skull of the four-legged animal. It is particularly worth noting that the four-legged animal moving state simulation device of this embodiment is mainly used for filming, and the actor rides on the fifth connecting rod 8, and the shooting part only stays on the actor's upper body and the torso and head of the four-legged animal leather case, and there is no need to shoot the feet of the four-legged animal, so the four-legged animal leather case usually does not have feet, so the bracket 1, the first telescopic rod 2 and the second telescopic rod 3 are exposed in the four-legged animal leather case.

[0062] The quadruped movement state simulation device provided in this embodiment can at least simulate the movement state changes of the upper body of the quadruped when the quadruped is in four movement states: slow walking, fast walking, jogging and fast running, by controlling the movement of the leather case.

[0063] The existing quadruped movement state simulation device needs to simulate not only the upper body of the quadruped, but also the foot.

[0064] In particular, during filming, only photographing the leather case of the upper body of the four-legged beast can meet the actual shooting requirements. In this application scenario, the four-legged beast movement state simulation device provided by this embodiment does not need to consider the simulation of the movement state of the four-legged beast's feet. On the one hand, the transmission structure of the four-legged beast movement state simulation device is greatly simplified, and the cost and failure rate are reduced. On the other hand, the design constraints of the four-legged beast movement state simulation device in the leather case are reduced, especially the adjustability of the relative position between the seventh rotation fulcrum 81 and the eighth rotation fulcrum 82 is increased, and then the different movement states of the four-legged beast can be more accurately expressed through the seventh rotation fulcrum 81 and the eighth rotation fulcrum 82.

[0065] It is particularly noteworthy that the quadruped movement state simulation device of this embodiment is particularly suitable for simulating the activity state of the upper body of a horse in different movement states. Therefore, this embodiment also provides a quadruped movement state simulation method for controlling the quadruped movement state simulation device to simulate the movement state of a horse.

[0066] The distance between the ninth rotation fulcrum 61 and the eighth rotation fulcrum 82 is L8, the distance between the sixth rotation fulcrum 42 and the seventh rotation fulcrum 81 is L9, and the distance between the seventh rotation fulcrum 81 and the eighth rotation fulcrum 82 is L 10 , satisfying L2:L3:L4=7.35:58.63:67.83, L5:L6:L8=67.83:35.69:41.10, L9:L 10 =26.33:130.

[0067] See also Fig.13 When the quadruped moving state simulation device simulates the slow walking of a horse, the motion trajectory of the eighth rotation support 82 satisfies the function The motion trajectory of the seventh rotation fulcrum 81 satisfies the function Wherein y1 represents the height difference between the eighth rotation fulcrum 82 and the second rotation fulcrum 12, y2 represents the height difference between the seventh rotation fulcrum 81 and the first rotation fulcrum 11, and t represents time.

[0068] See also Fig.14 When the quadruped moving state simulation device simulates a horse walking fast, the motion trajectory of the eighth rotation support 82 satisfies the function The motion trajectory of the seventh rotation fulcrum 81 satisfies the function Wherein y1 represents the height difference between the eighth rotation fulcrum 82 and the second rotation fulcrum 12, y2 represents the height difference between the seventh rotation fulcrum 81 and the first rotation fulcrum 11, and t represents time.

[0069] See also Fig.15 When the quadruped moving state simulation device simulates the horse jogging, the motion trajectory of the eighth rotation fulcrum 82 satisfies the function The motion trajectory of the seventh rotation fulcrum 81 satisfies the function Wherein y1 represents the height difference between the eighth rotation fulcrum 82 and the second rotation fulcrum 12, y2 represents the height difference between the seventh rotation fulcrum 81 and the first rotation fulcrum 11, and t represents time.

[0070] See also Fig.16 When the quadruped moving state simulation device simulates the horse running fast, the motion trajectory of the eighth rotation support 82 satisfies the function The motion trajectory of the seventh rotation fulcrum 81 satisfies the function Wherein y1 represents the height difference between the eighth rotation fulcrum 82 and the second rotation fulcrum 12, y2 represents the height difference between the seventh rotation fulcrum 81 and the first rotation fulcrum 11, and t represents time.

[0071] The positions of the seventh rotation fulcrum 81 and the eighth rotation fulcrum 82 are controlled by the above-mentioned simulation method, so that the movements of the horse's upper body leather cover can be well matched with the movements of the upper body of an actual horse when walking, walking, jogging and running. Accordingly, the four-legged animal movement state simulation device of this embodiment can at least meet the needs of simulating the four movement states of a horse walking, walking, jogging and running in film and television shooting.

[0072] In order to facilitate the actor to straddle the fifth connecting rod 8, the saddle 20 is installed on the fifth connecting rod 8, and the actor straddles the saddle 20 to facilitate the saddle 20 to keep synchronous movement. In some shooting scenes, it is necessary to show the scene of the actor falling from the quadruped, so the saddle 20 needs to be rotatably arranged on the fifth connecting rod 8.

[0073] See also Figure 7-Figure 12 Therefore, in this embodiment, the fifth connecting rod 8 includes a third connecting segment 83, a fourth connecting segment 84 and a fifth connecting segment 85. The quadruped mobile state simulation device also includes a rotating shaft seat 10. The third connecting segment 83, the rotating shaft seat 10 and the fourth connecting segment 84 are sequentially arranged on the same axis. The two ends of the rotating shaft seat 10 are respectively rotatably arranged on the third connecting segment 83 and the fourth connecting segment 84, so that the rotation center line of the rotating shaft seat 10 coincides with the axis of the fifth connecting rod 8. The fifth connecting segment 85 is located between the third connecting segment 83 and the fourth connecting segment 84. The fifth connecting segment 85 is not coaxial with the third connecting segment 83 and the fourth connecting segment 84, but the two ends of the fifth connecting segment 85 are respectively fixedly connected to the third connecting segment 83 and the fourth connecting segment 84, so that the third connecting segment 83 and the fourth connecting segment 84 are fixedly connected. The saddle 20 is mounted on the rotating shaft seat 10 and is located on the side of the rotating shaft seat 10 away from the bracket 1. Therefore, when the actor needs to perform a scene of falling from the four-legged beast, he will rotate around the axis of the fifth connecting rod 8 and fall with the saddle 20, thereby simulating the rotation and falling around the spine of the four-legged beast, and the authenticity of the performance is improved.

[0074] The fifth connecting section 85 is located on the side of the rotating shaft seat 10 and is spaced apart from the rotating shaft seat 10 , so as to avoid the rotating shaft seat 10 during the rotation of the rotating shaft seat 10 .

[0075] In order to further enhance the authenticity of the actor's fall performance, it is also necessary to enable the saddle 20 to move sideways on the rotating shaft seat 10. Specifically, the four-legged beast moving state simulation device also includes a side shift seat 30, which is located between the rotating shaft seat 10 and the saddle 20, and the saddle 20 is mounted on the rotating shaft seat 10 through the side shift seat 30, and a slide rail 301 is provided on the side shift seat 30, and a slider 101 is provided on the rotating shaft seat 10, and the slider 101 is slidably arranged on the slide rail 301, and the extension direction of the slide rail 301 is perpendicular to the fifth connecting rod 8. The side shift of the side shift seat 30 on the rotating shaft seat 10 can be achieved by the coordination of the motor gear rack, and the side shift control of the side shift seat 30 on the rotating shaft seat 10 is independent of the telescopic action of the first telescopic rod 2 and the second telescopic rod 3, and will not affect the simulation of the moving state of the four-legged beast.

[0076] Further preferably, an elastic buffer 302 is provided on the side shift seat 30, and the two ends of the elastic buffer 302 are respectively in contact with the side shift seat 30 and the saddle 20, and the axial direction of the elastic buffer 302 is perpendicular to the slide rail 301 and the fifth connecting rod 8. Therefore, when the fifth connecting rod 8 is moving, the elastic buffer 302 can cause the actor to shake to a certain extent, simulating a more realistic riding state.

[0077] A major difference between the four-legged beast moving state simulation device of this embodiment and the prior art is that the bracket 1, the first telescopic rod 2, the second telescopic rod 3, the first connecting rod 4, the second connecting rod 5, the third connecting rod 6, the fourth connecting rod 7, and the fifth connecting rod 8 are almost in the same plane, and the overall width of the four-legged beast moving state simulation device is very small. Therefore, the four-legged beast moving state simulation device of this embodiment also includes two thigh inner support blocks 40, and the two thigh inner support blocks 40 are fixed on the side shift seat 30. The two thigh inner support blocks 40 are arranged oppositely and spaced in the axial direction of the slide rail 301, so that the two thigh inner support blocks 40 are respectively located on both sides of the saddle 20. When the actor rides on the fifth connecting rod 8, the thighs can be spread apart by the two thigh inner support blocks 40, thereby simulating a more realistic riding state.

[0078] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0079] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
