This invention provides an adjustment device for a vehicle-mounted escalator, belonging to the field of automotive parts technology. The adjustment device includes a support frame with at least one bending member located in the middle of the support frame, dividing the support frame into at least two supports. The vehicle-mounted escalator includes a first rod and a second rod. The first rod passes through an adjustment space to position the second rod above the support frame. Each support has at least one slot for engaging the second rod. By engaging the second rod in either slot, movement of the vehicle-mounted escalator relative to the vehicle body in at least one direction is restricted. This design allows the vehicle-mounted escalator to be installed laterally between the vehicle body and the front of the vehicle during installation, thus changing its position and significantly reducing the space required between the vehicle body and the front of the vehicle, thereby reducing the overall length of the vehicle frame and lowering costs.

The application provides an antenna, a circuit board and an electronic device. The antenna comprises a first radiator and a second radiator arranged on a substrate. The substrate has a first structure layer and a second structure layer. The first structure layer is provided with a first hollow area, and the second structure layer is provided with a second hollow area. The first radiator is arranged in the first hollow area, and the second radiator is arranged in the second hollow area. The first radiator and the second radiator are arranged in a spaced manner along the thickness direction of the substrate. The substrate further has a ground layer. Two ends of the second radiator are connected to the ground layer for grounding. The first radiator is provided with a first gap, and a first end of the first radiator is connected to the ground layer for grounding. The antenna can effectively increase the aperture of the radiator, so that the magnetic field distribution of the antenna is more uniform, thereby effectively reducing the required clearance area of the antenna under the condition of meeting the same antenna performance, and further helping the miniaturization of the electronic device.

This utility model discloses a speaker sound outlet cavity structure, including a sound outlet cavity, a speaker, and a pad. The speaker is installed at the upper end of the sound outlet cavity, and the pad is installed at the lower end of the sound outlet cavity. The upper side of the pad has several spaced-apart recesses. One side of the sound outlet cavity has a sound outlet. The speaker and the pad are vertically opposite each other, with the speaker's sound output direction facing the upper side of the pad. The sound emitted by the speaker is reflected by the upper side of the pad and the recesses of the pad before being output from the sound outlet. This utility model can further improve sound loudness and bass effect, and can make the emitted sound have a stereo surround sound effect.

The utility model provides a motor stator device, which comprises an annular iron core, the iron core comprises an outer ring part and a winding part, the outer edge of the winding part is provided with a coil winding, an insulating bracket for isolating the coil winding and the winding part is arranged between the coil winding and the winding part, and the insulating bracket is provided with a limiting structure along the axial direction of the iron core. The position, corresponding to the limiting structure, of the iron core is provided with a matching structure in the axial direction of the iron core, the limiting structure and the matching structure are in sliding fit in the axial direction of the iron core so as to guide axial insertion positioning of the iron core and the insulation support, the iron core and the insulation support are guided to be assembled in place in the axial direction through the structure, and an additional positioning structure in the axial direction of the stator is provided. Relative rotation is prevented, the assembly difficulty is reduced during assembly, the relative positions of the iron core and the insulation support are easy to align, one-time accurate assembly can be achieved, the space allowance reserved between the iron core and the insulation support due to assembly requirements can be reduced as much as possible, and the integrity and reliability of the motor stator structure are further improved. The utility model also provides an electric water pump motor.
