Description

Technical Field

[0001] The utility model relates to the technical field of simulated animals, in particular to an arm rotating device for simulated animals. Background Art

[0002] Simulated animals are made by simulating the limb structure of animals. Through simulated animals, we can have a good understanding of the survival mode of animals. Simulated animals are usually made of a series of mechanical parts, and the movement effect is produced by combining various parts.

[0003] After searching, in the prior art, a Chinese patent with patent application number 201921516129.2 discloses a simulated animal forelimb activity mechanism, including a support plate, a bearing, a main gear, a driven gear, a spring, a first motor, a second motor and a pulley, wherein a bearing is arranged inside the support plate, and a rotating rod is installed inside the bearing, and a main gear is arranged in front of the rotating rod, and driven gears are arranged on both upper and lower sides of the main gear, and the left side of the rotating rod in the driven gear is connected to the forelimb, and the front side of the forelimb is connected to the forearm, a rotating shaft is arranged between the forelimb and the forearm, and a spring is connected between the forelimb and the forearm, and a bump is arranged below the forearm, a first motor is arranged at the end of the rotating rod on the rear side of the main gear, and a second motor is arranged on the left side below the first motor, and a bolt rope is connected to the front and rear sides of the second motor, but the following defects still exist:

[0004] (1) In the above patent documents, the forelimbs of the simulated animal are driven by a motor to drive the relevant gears to rotate, but the overall forelimb structure cannot move at different angles in the vertical direction, which limits the movement range of the forelimbs of the simulated animal and reduces the simulation effect;

[0005] In the above patent document, the forearm of the device is an integrated fixed structure. Since the length ratios of the limbs of the same animal are also different, the above device cannot simulate the movement states of different body shapes of the same animal, which reduces the simulation range of the device.

[0006] Therefore, we make improvements on this and propose an arm rotating device for simulating animals. Utility Model Content

[0007] The purpose of the utility model is to address the problem that the forelimbs of simulated animals are currently driven by motors to rotate related gears, but the overall forelimb structure cannot move at different angles in the vertical direction, which limits the movement range of the forelimbs of the simulated animals and reduces the simulation effect. The forearms of the device are integrated fixed structures. Since the length ratios of the limbs of the same animal are also different, the above-mentioned device cannot simulate the movement states of different body shapes of the same animal, thereby reducing the simulation range of the device.

[0008] In order to achieve the above-mentioned utility model purpose, the utility model provides the following technical solutions:

[0009] An arm rotating device for a simulated animal, comprising a mounting frame and:

[0010] A shoulder assembly, rotatably connected to the side wall of the mounting frame, for simulating shoulder joint movement, wherein the shoulder assembly includes a shoulder joint rotatably connected to the side wall of the mounting frame and a rotary hydraulic cylinder rotatably connected to the inner wall of the mounting frame, the rotary hydraulic cylinder drives the shoulder joint to rotate, and the shoulder joint and the rotary hydraulic cylinder are symmetrically distributed about the central axis of the mounting frame;

[0011] The upper arm assembly is rotatably connected to the inner wall of the shoulder joint and is used to simulate the upper arm movement of animals;

[0015] As a preferred technical solution of the utility model, the upper arm assembly includes a rotating shaft rotatably connected to the inner wall of the shoulder joint, a large arm fixedly connected to the output end of the rotating shaft, and a first telescopic arm slidably connected to the inner wall of the large arm.

[0016] As a preferred technical solution of the utility model, the transmission assembly includes a motor bracket fixedly connected to the inner wall of the mounting frame, a transmission motor fixedly connected to the inner wall of the motor bracket, a transmission shaft fixedly connected to the output end of the transmission motor, and a universal joint fixedly connected to the transmission end of the transmission shaft. The transmission motor drives the boom to rotate through the rotating shaft and the universal joint.

[0019] Compared with the prior art, the utility model has the following beneficial effects:

[0020] In the solution of the utility model:

[0021] 1. The rotating hydraulic cylinder is set to drive the shoulder joint and the upper arm to rotate. The setting of the shoulder joint increases the freedom of the forelimbs of the simulated animal during motion simulation. The transmission motor drives the rotating shaft and the upper arm through the transmission shaft and the universal joint to reciprocate about the specified frequency of the shoulder joint, simulates the movement of the upper arm of the forelimb of the simulated animal, and realizes the expansion of the motion range and freedom of the forelimb of the simulated animal during motion simulation. It solves the problem that the forelimb of the simulated animal is driven by the motor to drive the relevant gears to rotate in the prior art, but the overall forelimb structure cannot move at different angles in the vertical direction, which limits the motion range of the forelimb of the simulated animal and reduces the simulation effect.

[0022] 2. The first telescopic arm and the second telescopic arm are pushed to move by the first telescopic hydraulic cylinder and the second telescopic hydraulic cylinder, so that the upper arm and the lower arm of the simulated animal can be extended and retracted to different degrees, respectively, thereby realizing the simulation of the forelimb length ratio of other animals with different forelimb length ratios, and solving the problem that the forearm of the device in the prior art is an integrated fixed structure, and since the length ratios of the limbs of the same animal are also different, the above-mentioned device cannot simulate the movement states of different body shapes of the same animal, thereby reducing the simulation range of the device.

The setting of the shoulder joint 2 increases the freedom of movement of the forelimbs during animal movement simulation, so that the simulated animal can show more movements during movement simulation.

The hydraulic cylinder 5 is controlled to push the small arm 51 to reciprocate at a specified frequency about the upper arm 31 to simulate the movement state of the lower arm of the forelimb of the animal during movement. When it is necessary to simulate the movement of different animals, due to the different ratios of the forelimb lengths of different animals, it is necessary to control the first telescopic hydraulic cylinder 61 and the second telescopic hydraulic cylinder 62 to push the first telescopic arm 32 and the second telescopic arm 63 to move, so that the upper arm and the lower arm of the simulated animal are respectively telescoped to different degrees, so that the simulated movement of the simulated animal is more realistic.
