The utility model discloses a lower limb structure of a bionic humanoid robot, and aims to overcome the defects that the upper part of a leg structure of a robot is bloated, the inertia is large, and a force bearing arm is short. The thigh body and the shank body are hinged together, a thigh turnover seat is hinged to the upper portion of the thigh body, a knee joint assembly is installed on the thigh body and comprises a knee joint pusher and a knee joint connecting rod, the knee joint connecting rod is hinged to the shank body, and a knee joint ejector rod is hinged between the knee joint connecting rod and the thigh body; the knee joint pusher is hinged to the thigh body, and a telescopic rod of the knee joint pusher is hinged to the knee joint connecting rod. According to the bionic humanoid robot lower limb structure, the space utilization rate and mass inertia distribution are optimized, the upper portion is prevented from being bloated, and the bionic humanoid robot lower limb structure has good bionic performance, engineering practicability and expansibility.

The utility model discloses a long -type structure for cultural travel large -scale bionics beast, including head steel structure, nose main part steel structure part and nose head steel structure part, nose main part steel structure part includes the N motion joint that connects in proper order, and each motion joint includes deflector, pitch, deflection driver and pitch driver, and deflector is connected with the rotation of pitch, and deflection driver drives deflector to deflect motion relative to pitch, the pitch of N motion joint is connected with the deflector of N 1 motion joint, and the pitch driver of N motion joint drives the pitch to deflect motion relative to the deflector of N 1 motion joint. The utility model discloses through setting N motion joint realizes the action simulation of multiple degrees of freedom, has realized the swing of up and down and left and right and the rolling in the space different direction, has reached the excellent bionic effect and the high authenticity, can use to bionics elephant trunk to carry out the high -quality performance to satisfy the demand of cultural travel market.

The invention relates to a variable-rigidity metatarsophalangeal joint based on torsion spring and connecting rod combination and a foot type robot. The variable-rigidity metatarsophalangeal joint comprises a rear sole, a front sole, a metatarsophalangeal joint rotating shaft, a torsion spring, a connecting rod, a supporting and pulling rod and a driving module. The front sole is rotationally connected with the rear sole through a metatarsophalangeal joint rotating shaft; the supporting and pulling rod is connected to the driving module and the connecting rod, the metatarsophalangeal joint rotating shaft is sleeved with a spring ring of the torsional spring, the torsional spring is hinged to the other end of the connecting rod, and the other end of the torsional spring is connected with the forefoot; the driving module is fixedly arranged on the rear sole and used for driving the supporting and pulling rod to reciprocate along the rear sole. The supporting pull rod slides to drive a spring coil of the torsional spring to rotate forwards or reversely around a metatarsophalangeal joint rotating shaft through the connecting rod, and the front foot sole is driven to do back stretching or plantar flexion movement relative to the rear foot sole. The supporting and pulling rod enables the torsion spring to generate different torsion angles when the front sole bears external force at different sliding positions, the rigidity of metatarsophalangeal joints is changed, back stretching and plantar flexion movement can be actively achieved, and meanwhile the rigidity and angle adjusting capacity is achieved.

The application provides a bionic fish multi-degree-of-freedom flexible tail structure, which comprises a driving assembly, a shape maintaining shell assembly and a flexible skin. The driving assembly is composed of at least two integrated double-degree-of-freedom motors in series. The output shaft of the transverse rotation degree-of-freedom end of the front motor is connected with the output shaft of the flapping degree-of-freedom end of the rear motor through a connecting piece. The output shaft of the flapping degree-of-freedom end of the frontmost motor is rotatably connected with the rear end surface support plate of the trunk unit through a trunk unit connecting piece. The output shaft of the transverse rotation degree-of-freedom end of the rearmost motor is rotatably connected with a tail fin skeleton through a tail fin connecting piece. The motors and the connecting piece are provided with connecting interfaces of the shape maintaining shell for connecting and fixing the shape maintaining shell at corresponding positions. The flexible skin is sleeved outside the shape maintaining shell assembly, and the internal contour of the flexible skin is complementary to the shape of the shape maintaining shell assembly. The application has the advantages of compact structure, large number of degrees of freedom, small movement resistance and mute characteristics.

The invention discloses a bionic breathable wooden sole based on modularization, relates to the technical field of footwear accessories, and aims at solving the problems that an existing synthetic material sole is poor in environmental protection property, and a traditional wooden sole is insufficient in comfort and breathability and the like. The wooden shoe sole comprises a shoe sole body, the shoe sole body is composed of a wood block set and a connecting body, the wood block set is composed of a plurality of wood block units made of natural wood materials, and each wood block unit comprises an instep wood block, a sole wood block and a connecting part; the connecting bodies are connected with the wood block units in two different modes, the flexible connecting bodies achieve penetrating type connection so as to guarantee the flexibility, and the hard connecting bodies achieve bottom clamping groove type connection so as to guarantee the structural stability; instep straps can be additionally arranged to achieve firm binding and convenient adjustment. By means of the modular design, the sole has excellent bionic adaptability and softness, the three-dimensional breathable channels are formed through gap penetration, the advantages of being environmentally friendly, safe, comfortable, breathable and flexible in structure are considered, and the sole is suitable for various daily wearing scenes.
