The invention discloses a bionic fishtail dual-drive device and a bionic fishtail structure. The bionic fishtail dual-drive device comprises a first drive assembly, a second drive assembly and a differential assembly. The differential assembly includes: a first input shaft and a second input shaft; the differential mechanism comprises a first half axle gear, a second half axle gear and a differential mechanism shell, a planetary gear shaft is installed in the differential mechanism shell, and a first planetary gear and a second planetary gear are installed at the two ends of the planetary gear shaft respectively; the driving gear and the driven gear are meshed with each other, the driving gear is installed on the first input shaft, and the driving gear is connected with the differential mechanism shell; and the driven gear is mounted on the output shaft. According to the bionic fishtail structure, the dual-drive device is adopted, the first input shaft and the second input shaft are connected with the first half axle gear and the second half axle gear correspondingly, so that the first planetary gear and the second planetary gear are driven to rotate, the differential mechanism shell is further driven to rotate, the driving gear is connected with the differential mechanism shell, and the driven gear is connected with the output shaft; therefore, a stable speed is output through the dual-drive assembly, the problem that the driving torque of a single motor is insufficient is solved, and meanwhile the problem that the driving speeds of dual motors are not coordinated is solved.

    本发明公开了一种仿生鱼尾双驱动装置及仿生鱼尾结构,包括:第一驱动组件、第二驱动组件以及差速器组件;所述差速器组件包括:第一输入轴和第二输入轴;第一半轴齿轮和第二半轴齿轮,差速器壳体,所述差速器壳体内安装有行星齿轮轴,所述行星齿轮轴的两端分别安装有第一行星齿轮和第二行星齿轮;相互啮合的主动齿轮和从动齿轮,所述主动齿轮安装在所述第一输入轴上,且所述主动齿轮与所述差速器壳体相连接;输出轴,所述从动齿轮安装在所述输出轴上。本申请中仿生鱼尾结构采用双驱动装置,第一输入轴和第二输入轴分别连接着第一半轴齿轮和第二半轴齿轮,从而带动第一行星齿轮和第二行星齿轮转动,进一步带动差速器壳体转动,而主动齿轮连接差速器壳体,从动齿轮连接着输出轴,从而实现通过双驱动组件输出一个稳定的速度,避免了单电机驱动扭矩不足的问题,同时克服了双电机驱动速度不协调的问题。
