This utility model discloses a multi-level adjustable brush, including a brush head assembly, a handle assembly, and a rotatable connecting component. One end of the connecting component is connected to the handle assembly, and the other end is connected to the brush head assembly. The brush head assembly can rotate to one end of the handle assembly via the connecting component. The user holds the handle assembly and uses the brush head assembly at the other end to clean stains. A movable locking block is provided on one side of the connecting component. In the normal state, the connecting component is in a locked state, where the locking block holds the connecting component and restricts its rotation, preventing the brush head assembly from rotating during brushing. In the unlocked state, manually pressing the locking block releases the locking state between the locking block and the connecting component, allowing the connecting component to rotate freely for adjustment. After releasing the locking block, the return spring returns the locking block to its original position, re-locking the connecting component. Users can adjust the brush to a suitable level according to their cleaning needs in different scenarios. The adjustment method is also relatively simple, satisfying the user's convenience.

The utility model discloses an anti-slip fastener which comprises a first fastener and a second fastener which can be opened and closed in a rotating mode, a braid is wound on the first fastener and the second fastener in an S shape, and the first fastener and the second fastener are closed in a rotating mode to clamp the braid, so that the braid is not prone to loosening and high in stability. The end parts of the first buckle and the second buckle are provided with connecting parts, the first buckle and the second buckle are rotationally connected through the connecting parts, at least one locking part is arranged between the first buckle and the second buckle, and the connecting relation between the first buckle and the second buckle is further reinforced through the locking part after closing, so that the first buckle and the second buckle are prevented from being automatically opened under the influence of external force in the use process; and bad experience is prevented from being brought to consumers.

This invention discloses a method, device, system, and vehicle for adjusting the horn volume when using a car key for vehicle locating. The method includes: receiving a vehicle locating command transmitted from the car key and measuring the radio frequency signal of the command to obtain a target signal strength range; querying a pre-set first mapping table to obtain a corresponding target distance range based on the target signal strength range; querying a pre-set second mapping table to obtain a corresponding target volume value based on the target distance range; querying a pre-set third mapping table to obtain a corresponding target PWM signal based on the target volume value; and adjusting the vehicle horn according to the target PWM signal to achieve the target horn volume. This invention avoids poor user experience due to inappropriate horn volume and improves overall vehicle safety. This invention is primarily applicable to the field of vehicle technology.
