Abstract: The disclosure discloses a milk protein concentrate-based microencapsulation wall material and microcapsules, and belongs to the technical field of microcapsule preparation. In the disclosure, liquid or solid microcapsules are prepared by performing cation exchange treatment on milk protein concentrates, and then using the treated milk protein concentrates as a wall material. The prepared microcapsules have good physical and chemical stability during storage, and are suitable for protecting active functional factors and to be applied in the fields of food, medicine, health care products, cosmetics, daily chemicals and the like.

Abstract: Provided are a current collector assembly, a battery cell, and a battery pack. The current collector assembly includes a plurality of layers of tabs, a protection plate, a connection plate, and at least one protrusion. The plurality of layers of tabs is stacked in a thickness direction of each of the tabs. The protection plate is arranged at a side of the plurality of layers of tabs in the thickness direction of each of the tabs. The connection plate is arranged at another side of the plurality of layers of tabs in the thickness direction of each of the tabs. The at least one protrusion is arrange between the connection plate and the protection plate. Each of the at least one protrusion penetrates the plurality of layer of tabs, and is connected to the plurality of layers of tab.

Abstract: Embodiments of the present disclosure provide a rotor, a motor, a powertrain, and a vehicle. The rotor includes wedges and pole shoes. The wedges fit the pole shoes through curved portions. The curved portions can effectively relieve stress concentration of joint portions, increase strength of the wedges and the pole shoes, and effectively increase effective winding space of slots in the rotor. In this way, power density of a motor in which the rotor is used is increased.

Abstract: The invention relates to the field of scooters, in particular to an electric scooter. The electric scooter comprises a scooter body having a top surface allowing a driver to stand thereon, a handlebar is arranged on a front portion of the scooter body, a rear mounting structure is arranged at the bottom of a rear portion of the scooter body, which allows a user to select either one of two rear members, which are a driving wheel and a driving caterpillar track, as a rear landing member to be detachably mounted on the rear mounting structure. The electric scooter can adapt to different landing members and can easily pass through complex roads such as muddy roads, snowy roads or desert roads using different landing members, thus being suitable for a wide range of scenarios.

Abstract: Provided are a connector, a battery cell, and a battery pack. The connector is configured to electrically connect a plurality of layers of tabs of an electrode plate. The connector includes a connection plate and a protrusion arranged at the connection plate. The protrusion protrudes from a side surface of the connection plate in a thickness direction of the connection plate, and is configured to penetrate the plurality of layers of tabs.

Abstract: This application relates to the field of motor technologies, and provides a motor rotor, a drive motor, and an electric vehicle. In the motor rotor, a rotor core with at least two protruding components is designed. At least two magnetic steels and at least two sheets are disposed in grooves between the at least two protruding components and then coupled to the rotor core with a rotor pressing plate. In addition, one SMC sheet is stacked on each of the magnetic steels, so that an eddy current loss of a permanent magnet can be effectively reduced. Each of the magnetic steels is disposed in a groove between protruding components, and the SMC sheet is added, so that a saliency ratio is increased, a reluctance torque ratio is increased, and a quantity of magnetic steels for use is reduced.

Abstract: A terminal having an infrared remote control function and a pairing method for infrared remote control, where in the terminal, a memory stores an infrared code library, a processor selects an infrared code from the infrared code library, an infrared transmitter sends an infrared signal to a to-be-remotely-controlled device according to the infrared code, a sensor senses a status change of the to-be-remotely-controlled device that occurs after the to-be-remotely-controlled device receives the infrared signal, and the processor determines, according to the status change of the to-be-remotely-controlled device sensed by the sensor, whether the terminal successfully establishes a pairing with the to-be-remotely-controlled device. Therefore, the terminal automatically establishes the pairing with the to-be-remotely-controlled device, and an automation degree of a pairing process during intelligent remote control is improved.
