The invention discloses a reflector adjustable device which comprises a reflector support 1, a reflector fixing seat 2, elastic pieces 3, an elastic piece fixing screw 4 and reflector adjusting screws5. When the device is used, a reflector is placed on the reflector fixing seat firstly, the reflector can be prevented from being scratched or crushed due to the fact that the reflector makes directcontact with the elastic pieces in the adjusting process due to the structural design, and then the reflector fixing seat is fixed to the reflector support through screws. Meanwhile, the elastic pieces on the two sides are fixed to the reflector support through screws, the elastic pieces are provided with bent pressing contact parts, the bent pressing contact parts have good elasticity, and it isguaranteed that the elastic piece pressing contact parts can abut against the reflector fixing seat all the time in the screwing-in and screwing-out process of the adjusting screws. And meanwhile, thefine adjustment effect of the reflector can be realized by screwing the four adjusting screws into or out of the support.

An electric vehicle, having a floor assembly (21) of a vehicle body structure (20), the floor assembly (21) at least comprising: side longitudinal members (24, 25), front cross members and rear cross members (26, 27), a vehicle floor (30) extending at least in sections between the longitudinal and cross members, and the passenger compartment floor (31), in the rear section of the floor assembly, the rear seats (13) in the rear section The vehicle is mounted on the passenger compartment floor above the passenger compartment floor (30), and an equipment space (32) is formed between the passenger compartment floor and the vehicle floor (31). The electric vehicle also includes at least one electric machine (16) and a traction battery (17) arranged below and mounted on the floor assembly (21). The rear cross member (27) extends from the passenger compartment floor (31) into the region of the vehicle floor (30) and closes off the equipment space at the rear end. The traction battery (17) is mounted on the side longitudinal beams and the front and rear beams and is sealed all around.

The invention discloses a household sewage treatment device, which comprises a treatment box. The inner top of the treatment box is horizontally arranged with primary rough cutting knives and secondary fine cutting knives from top to bottom, and the top surface of the treatment box is installed with A motor box that drives the differential rotation of the primary rough cutting tool and the secondary fine cutting tool. Cleaning brushes are installed on one side of the primary rough cutting tool and the secondary fine cutting tool. A residue storage box for residues, the bottom of the residue storage box is provided with a filter box that communicates with the bottom of the residue storage box, and the filter box is installed on the inner bottom surface of the treatment box through the two sides of the bottom surface as a whole. The left and right inner walls are equipped with a telescopic cover device with automatic stretching and used to cover the residue in the residue storage box; the invention can improve the crushing efficiency, automatically clean the cutter, and the gland plate can clean the residue in the residue storage box. Compacting and squeezing water improves the actual storage capacity of the residue storage box.

The invention provides a pedal mechanism which is easy to disassemble. The pedal mechanism comprises a pedal bracket, a return spring, a pedal arm, and a rotary connecting component, wherein a pin shaft is fixed to the petal bracket; the main body of the rotary connecting component adopts a disk-shaped structure, a first pin hole is formed in the center of the main body, and the main body extends to the same side to form a plurality of first limiting bosses and a first second limiting boss; the second limiting boss is provided with a first groove which is close to the first pin hole and a second groove which is far away from the first pin hole, a second pin hole is formed in one end of the pedal arm, and first sinks and a second sink are formed in one end of the pedal arm; the pin shaft sequentially penetrates through the first pin hole and the second pin hole, and the first sinks of the pedal arm are matched with the first limiting bosses, and the second sink is matched with the first groove in the second boss; the first limiting bosses and the second limiting boss transmit the rotational movement of the pedal arm, and the first groove limits the axial movement of the pedal arm; one end of the return spring is connected with the pedal bracket, and the other end of the return spring is clamped to the second groove. According to the pedal mechanism disclosed by the invention, the disassembly convenience and the safety of the pedal mechanism are improved.
