Description

Technical Field

[0001] The utility model relates to the technical field of gear rack assemblies, in particular to a gear rack transmission assembly for a mobile power exchange device. Background Art

[0002] The rack and pinion transmission assembly in the mobile battery swap device is a key component used to realize the lifting or lateral movement function of the battery swap device. It usually includes a rack and a gear meshing with it. The movement of the rack is achieved by the rotation of the gear, thereby driving the battery swap device to move up and down or left and right. These components play an important role in the battery swap device.

[0003] For example, the publication number CN107143628B discloses a rack and pinion transmission assembly and a transmission device including the transmission assembly. The rack includes bevel teeth and flat teeth that are alternately arranged along the transmission direction of the rack; the front end face and the rear end face of the bevel teeth are both planes, the plane perpendicular to the transmission direction of the rack is the first plane, and the angles between the front end face and the rear end face and the first plane are both acute angles, the plane parallel to the transmission direction of the rack and perpendicular to the first plane is the second plane, and the angles between the front end face and the rear end face and the second plane are both acute angles; in the straight line direction parallel to the first plane and the second plane, the length of the bevel teeth is greater than the length of the flat teeth; the tooth surfaces on both sides of the gear teeth are respectively connected to the end faces of adjacent gear teeth through chamfered surfaces, and the two adjacent chamfered surfaces intersect at an intersection line.

The instability during movement will affect the accuracy of the battery swapping work, thereby reducing the use effect of the transmission equipment. Therefore, we propose a gear rack transmission assembly for a mobile battery swapping device to solve the above problems. Utility Model Content
