We make a detailed study of the photoproduction mechanism of the doubly heavy flavoredmeson at the purposed Large Hadron Electron Collider (LHeC) within the framework of nonrelativistic QCD. In addition to the photoproduction mechanism via the gluon-induced channel, the extrinsic heavy quark mechanism via the two channelsandhas also been studied. Those two extrinsic channels are generally suppressed by the heavy quark distribution functions in the proton, which provide significant contributions in the low and intermediateregion. A detailed comparison of those channels together with the theoretical uncertainties has been presented. By summing up all the mentioned photoproduction channels, we observe that aboutandevents can be generated at the LHeC in one operation year with the proton-electron collision energyand the luminosity. Here the errors are forand. Thus, in addition to the hadronic experiments, the LHeC shall provide another helpful platform for studying themeson properties, especially to test the extrinsic heavy quark mechanism.
