Abstract: An example includes a housing, a stator assembly, a rotor, and a self-cooling structure. The stator assembly is mounted on the housing and fitted around the rotor, the rotor is rotatably housed within the housing, the self-cooling structure is attached to the rotor, and the self-cooling structure is located at the stator assembly. The self-cooling structure comprises an outer cylinder, an inner cylinder, and a plurality of blades, wherein the plurality of blades are radially connected between the inner cylinder and the outer cylinder. A ventilation slot is formed between the outer cylinder and the inner cylinder, with multiple end-face air intake holes formed at the ventilation slot, and side exhaust holes are formed between adjacent two blades, with the end-face air intake holes being in communication with the side exhaust holes. In this way, it is capable of actively dissipating heat within the motor without altering its form.

Abstract: The invention relates to a wiper blade device, comprising a wiper blade adapter (10; 10a; 10b), which has at least two locking means (12; 12a; 12b, 14; 14a; 14b), which are arranged at an offset from each other in a wiper blade longitudinal direction (16; 16a; 16b), and comprising at least one spring rail (18; 18a; 18b), which has at least two locking cut-outs (20; 20a; 20b, 22; 22a; 22b), which are arranged at an offset from each other in the wiper blade longitudinal direction (16; 16a; 16b), wherein the at least two locking means (12; 12a; 12b, 14; 14a; 14b) are provided for engaging in the at least two locking cut-outs (20; 20a; 20b, 22; 22a; 22b) of the at least one spring rail (18; 18a; 18b) in an assembled state.
