Abstract: Off-road vehicle includes a frame, wheels, a locomotive power system, and a drive train. The frame includes a rear frame positioned at the rear of the frame, and the rear frame defines a receiving space. The wheels supports under the frame and includes front wheels and rear wheels. The locomotive power system includes a drive motor for driving the wheels and a range extender for outputting electrical energy to provide energy for the drive motor. When viewed from a width direction of the off-road vehicle, the drive motor overlaps at least partially with the range extender; when viewed from a length direction of the off-road vehicle, the drive motor overlaps at least partially with the range extender, and the drive motor is at least partially positioned behind the range extender. This arrangement can make the off-road vehicle more compact.

Abstract: A stop valve is provided. A stop valve includes a valve body, a valve core and a connecting block. The valve body is provided with a first opening and a second opening. The valve core is movable in the valve body to communicate the first opening with the second opening and cut off a communication therebetween. One end of the connecting block is located outside the valve body, the other end thereof is fixedly connected to an end of the valve body. A part of the valve core extends into the connecting block and is in threaded fit with the connecting block. The connecting block extends towards the valve body to define a seal portion along an axis of the valve core. When the stop valve is in a fully opened state, the valve core is capable of abutting against the seal portion and forming a linear seal therewith.

Abstract: A stop valve, including: a valve tube, wherein two ends thereof are respectively an operating end and a plugging end, a side wall of the valve tube is provided with a first interface and a second interface, the second interface is close to the plugging end relative to the first interface, and a space between the second interface and the plugging end in the valve tube forms a buffer chamber; a base, used for plugging an opening of the plugging end; a sleeve ring, fixed in the cavity of the valve tube, the sleeve ring is provided with a valve port; and a valve core, disposed in the cavity of the valve tube, so as to close or open the valve port; and the valve tube and the base both are made of stainless steel.

Abstract: A stop valve and a refrigeration system having the same are provided. The stop valve includes: a valve body, which is provided with a valve port; and a valve core, which is at least partially provided inside the valve body and capable of moving in the valve body along an axis of the valve body to seal or open the valve port. A side of the valve core towards the valve port is provided with a first groove, a first sealing member is embedded in the first groove, the first sealing member is in interference fit with the first groove, a restricting portion is provided on the inner surface of the first groove, and the restricting portion can restrict the first sealing member.

Abstract: An anti-disassembly connector, including: a connecting portion, where a threaded connecting section is disposed on the connecting portion; and bosses, where the bosses protrude from an end or a peripheral wall of the connecting portion, each of the bosses extends along a circumferential edge or the peripheral wall of the connecting portion, each of the bosses has a force-bearing surface and a force-releasing surface that are disposed opposite to each other, at least two bosses are arranged, the two bosses are disposed at intervals along the circumferential edge or the peripheral wall of the connecting portion, and a gap between two adjacent bosses forms a clamping interval. A force-bearing sideline is formed on a side of the force-bearing surface away from an inner wall of the connecting portion, a length of the force-bearing sideline is L, and 5 mm<L<20 mm.

Abstract: Disclosed is a cycloidal pinwheel pair with uniform contact and one-tooth difference, comprising a stator and a rotor. Each gear tooth profile of the rotor has a modified recess provided symmetrically on both sides; the starting point (A) of the modified recess on one side of the gear tooth profile is located between a first point and a second point determined by locations of two limit positions, the end point (B) of the modified recess on the same side of the gear tooth profile is located between a third point and a fourth point determined by locations of two limit positions. By adopting the present disclosure, the internal leakage formed between high and low pressure chambers is effectively avoided, thereby significantly improving the volume efficiency and mechanical efficiency. Meanwhile, the present disclosure is extremely simple in structure and can be molded by one-time grinding with better manufacturability.
