Adopt above-mentioned technical scheme, increase the shaft coupling device between motor element and lead screw, the shaft coupling is connected with motor element through the spline on the adapter, the lead screw realizes connecting in inserting the spline groove in the adapter, through first grafting piece and first slot between the shaft coupling, the grafting relation of second grafting piece and second slot carries out the linkage combination, wherein first slot is the cross distribution with the second slot relatively, make the torsion between the shaft coupling can the average distribution, be unlikely to make the grafting piece deviate from the slot, when the motor circular telegram, the motor rotates the moment of torsion and transmits the lead screw through the shaft coupling, there is the buffer block because of the shaft coupling is inside, can effectively eliminate the deviation adverse effect that the assembly process brought, abnormal sound and the shake that the in-process that the motor moment of torsion that can significantly reduce transmitted the lead screw.
The coupler device for the electric tail gate stay bar of the automobile can be further set as follows: the first insertion block can slide along the first slot, the second insertion block can slide along the second slot, and the buffer block is made of soft rubber.
By adopting the technical scheme, the first inserting block can horizontally slide along the first slot, so that the spline on the adapter can be finely adjusted along with the horizontal direction of the adapter, and the second inserting block can horizontally slide along the second slot, so that the spline groove on the adapter can also be finely adjusted along with the horizontal direction of the adapter, the shaft coupling can tolerate large radial and angular deviations, and the load of the shaft center is reduced.
The coupler device for the electric tail gate stay bar of the automobile can be further set as follows: the outer peripheral surface of the adapter is provided with at least two shaft holes which are oppositely arranged, a detachable jackscrew is arranged in each shaft hole, and the jackscrew can be abutted against the spline grooves when being loaded.
By adopting the technical scheme, the plurality of shaft holes are formed in the outer wall of the adapter, and the jackscrews can be screwed in the shaft holes, so that the jackscrews are fixed in the spline grooves, the relative movement between the spline grooves and the lead screws is prevented, and the problem of idle running of the lead screws and the spline grooves after the service life is too long is solved.
The coupler device for the electric tail gate stay bar of the automobile can be further set as follows: the number of the shaft holes is 4.
The utility model has the advantages that: the adapter, the buffer block and the adapter are connected in an inserting mode through a cross inserting connection relation, the first inserting block can slide along the first inserting groove, the second inserting block can slide along the second inserting groove, the adverse effect of deviation caused by the assembling process is effectively eliminated, and abnormal sound and shaking generated in the process that the motor torque can be greatly reduced and transmitted to the screw rod are greatly reduced.
The present invention will be described in further detail with reference to the accompanying drawings and examples.
