Problems solved by technology
The problem existing in the application of accumulators in bionic robots is that the multi-point layout of the accumulators is inconvenient, so that the accumulators and hydraulic actuators cannot correspond one-to-one, which affects the response speed of the hydraulic actuators; the existing accumulators It does not match the bone of the bionic robot, and it is not easy to install or even impossible to install. In addition, due to the shape, volume and connection form of the accumulator itself, the volume and weight of the bionic robot become larger, the shape is too bloated, and the response is not sensitive

Embodiment Construction
[0010] refer to figure 1 , the present invention comprises housing 2, interface valve group 22, air bag 23 and pressure sensor 25; And communicate with the inner cavity of the housing 2; there are several airbags 23, the material of which is synthetic rubber, with an inflation port 24 on it, the airbag 23 is located in the inner cavity of the housing 2, and the inflation port 24 extends out of the housing 2 ; The interface valve group 22 is provided with an electromagnetic switching valve 221 and a charging valve 222 .
[0011] The present invention is described in detail below in conjunction with accompanying drawing:
[0012] a) Assembly of bone accumulator
[0013] refer to figure 1 , due to the different functions of various parts of the bone, the shape and shape of its design are also quite different. Therefore, the shape of the shell 2 of the accumulator 1 depends on the shape of the bone and the cavity 11 inside the bone, but the shape of the bone The difference doe...

The invention discloses a hydraulic accumulator in an bionic bone, which is characterized by comprising a casing, an interface valve group, a plurality of air bag and a pressure sensor, wherein the casing is a closed container shaped like a bone; the interface valve group and the pressure sensor are arranged on the casing and run through the inner cavity of the casing; charging openings are formed in the air bags arranged in the inner cavity of the casing, and extend out of the casing. The hydraulic accumulator is arbitrary in shape, has a simple structure, is arranged in the bionic bone, improves the movement ability of a bio-robot, and enables the bio-robot to have the characteristics that the response speed is high, the impact load resistance is high, the flexibility is strong, the structure is compact, and the connection with a hydraulic system is convenient.
Description
technical field [0001] The invention relates to the technical field of bionic robots, and is used for a hydraulically driven bionic robot, a robot skeleton and an accumulator for an integrated design, which is not only a robot skeleton, but also a hydraulic accumulator. Background technique [0002] The accumulator is a commonly used hydraulic component in the hydraulic system. Its main purpose is to realize the rapid driving of the hydraulic actuator and reserve hydraulic power, and it has the function of transmitting or recovering energy from the hydraulic system. At present, the accumulators used in bionic robots are divided into three types: bladder type, diaphragm type and plunger type. Through the motion analysis of bionic quadruped walking bionic robots, it is not difficult to find that when bionic robots are jumping, energy storage is required. The accumulator outputs energy to the hydraulic actuator and can respond quickly; when the bionic robot falls, the accumulat...
