The invention provides a mobile robot suspension damper with double combined spiral springs, and belongs to the field of the shock absorption technology. The mobile robot suspension damper is mainly applied to shock absorption between a mobile robot suspension and a wheel-leg hybrid mechanism. The mobile robot suspension damper comprises an installation support, a damper shell, a connection sleeve, a connection shaft, the upper spiral spring, the lower spiral spring and a wheel-leg support. The shock absorption comprises two stages, the first stage is a vertical upward shock absorption process, specifically, vibration energy from the wheel-leg support enables the connection sleeve to move upwards to compress the upper spiral spring, the vibration amplitude is reduced through the spring damping effect, and the lower spiral spring is stretched at the same time; the second stage is a vertical downward shock absorption process, under the elastic force effect of the upper spiral spring and the lower spiral spring, the connection sleeve moves downwards to compress the lower spiral spring, the vibration amplitude is reduced through the spring damping effect, and the upper spiral spring is stretched at the same time. The damper can buffer and attenuate the vibration energy from the wheel-leg support, so that large vibration energy is prevented from being transmitted to the mobile robot suspension through the installation support.
