The motor housing has a first end and a second end along an axial direction of the motor shaft. An output end of the motor shaft extends out of the motor housing from the first end of the motor housing. The motor controller is arranged on an outer end face of the second end of the motor housing. The control panel is arranged on an outer wall of the housing and is connected to the motor controller.

Abstract: A self-adjusting pre-tensioning device for a roller shade includes a brake assembly and a spring, where the roller shade includes a core rod, a fixed brake member, a support roller. The brake assembly is arranged at a first end of the core rod. The fixed brake member and the support roller are arranged at a second end of the core rod. The brake assembly includes a rotary outer sleeve, a sleeve seat, a clutch mechanism and a mounting frame. The rotary outer sleeve is circumferentially provided with a plurality of ratchet teeth. The clutch mechanism includes a locking pawl, which are configured to be radially movable, and to engage with the plurality of ratchet teeth to form a one-way locking mechanism. The mounting frame is provided with an unlocking tongue configured to be slidably inserted into the sleeve seat.

Abstract: A screw-free curtain fixing mechanism includes a fixing track for mounting a roller shade. At least one end of the fixing track is provided with an extendable abutting assembly configured for abutting against a mounting surface, which includes a locking portion and an abutting portion. The locking portion is slidably connected to the fixing track, and is provided with a locking mechanism configured for forming a releasable locking engagement with the fixing track. A first end of the abutting portion is configured to extend out of an end of the fixing track where the locking portion is located. A second end of the abutting portion is in drivable fit with the locking portion. A fine-adjustment component is arranged on the extendable abutting assembly.

Abstract: The present invention relates to the field of disease therapy and immunology. Specifically, disclosed are an anti-CD73 antibody or an antigen-binding fragment thereof, a nucleic acid molecule encoding same, an immunoconjugate comprising same, a bispecific molecule and a pharmaceutical composition, as well as use thereof in enhancing immune response and/or treating tumors.

Abstract: A positive electrode plate includes a positive electrode current collector and a positive electrode active material layer. A safety coating is provided between the positive electrode current collector and the positive electrode active material layer, and the safety coating is disposed on a surface of the positive electrode current collector. The safety coating contains substance I, and the substance I is formed by dehydration of a first substance via a drying process of the positive electrode plate, where the first substance includes silica sol and/or alumina sol. The surface of the current collector of the positive electrode plate is provided with the safety coating, where the safety coating has good high-temperature resistance and can effectively protect the aluminum foil at high temperatures, thereby enhancing the thermal safety performance of the lithium-ion battery.

Abstract: The present disclosure relates to an antenna angle adjustment device, and the angle adjustment device includes a drive member (10) and a driven member (4). The drive member is supported rotatably around a first rotation axis (X1) and can be manipulated and fixed. The driven member is supported rotatably around a second rotation axis (X2), and the angular position of the driven member is related to the angular position of the antenna. The drive member has an engagement point, and the driven member has a concave curved portion. The engagement point extends into the curved portion and engages the curved portion so that the rotation of the drive member around the first rotation axis can cause the rotation of the driven member around the second rotation axis. The present disclosure further relates to an antenna with the angle adjustment device. The angle of the antenna can be appropriately adjusted by the angle adjustment device.
