Detection of non-gravitational interactions of massive dark matter with visible sector so far have given null results. The DM may communicate with the ordinary matter only through gravitational interactions. Besides, the majority of traditional direct detections have poor sensitivity of searching for light DM particle because of the small recoil energy. Thanks to the high energy cosmic rays (CRs), the light DM can be boosted by scattering with CRs and thus may be detected in those existing experiments. In this work, we first derive the exclusion limits of the cosmic ray boosted sub-GeV Dark Matter with gravitational mediator from the Xenon1T data.
