The invention discloses an automobile motor shock-absorption cushion and a motor installation structure thereof. A connection hole I is arranged in the middle of an air inflation ring; a pressure indication film is arranged on the air inflation ring; a wearable cushion is arranged at the upper part of the air inflation ring; a connection hole II mutually corresponding to the connection hole I of the air inflation ring is arranged on the wearable cushion; an inflating valve is arranged on the air inflation ring; and mutually matched cover bodies are arranged on the inflating valve. The automobile motor shock-absorption cushion and the motor installation structure thereof provided by the invention are simple in structure, convenient to install, good in shock-absorption effect and rapid in heat dissipation efficiency; air pressure in the shock-absorption cushion can be simultaneously detected through the pressure indication film; therefore, the shock-absorption effect is ensured; simultaneously, the motor is more stable; and the practicability is relatively high.
