The invention discloses an electric bus battery box locking and unlocking device, which comprises a worm gear and worm motor (1), a turntable (2) connected with the output shaft of the worm gear and worm motor (1) and arranged at the bottom of the worm gear and worm motor, two connecting rods (3) symmetrically connected to two sides of the turntable through pin shafts (7), two swing rods (6) symmetrically connected to the other ends of the two connecting rods (3) through rotating pins (8) respectively, two L-shaped bent plates (5) symmetrically and fixedly connected to the outer ends of the swing rods, and two wedge-shaped pressure block members (4) symmetrically connected to the other ends of the L-shaped bent plates. The device can automatically apply a locking force to a battery box, so that the battery box is tightly combined with the vehicle body, jump and impact of the battery box in jolt are effectively prevented, and running safety of the vehicle is ensured; and meanwhile, thedevice is convenient for unlocking to realize quick change of the battery box.

The invention provides a camshaft toggle solenoid valve for a variable valve lift system applied in the technical field of an engine variable valve lift system. The camshaft toggle solenoid valve for a variable valve lift system includes a casing ( 1), the casing (1) is provided with an electromagnetic coil (2), the electromagnetic coil (2) is provided with a sleeve (3), the sleeve (3) is provided with a magnetic core body (4), and the magnetic core body (4) is connected with the drive The rod (5) is connected, and a strong magnet (6) is arranged at one end of the shell (1), and the magnetic core body (4) is close to the strong magnet (6). The variable valve lift system of the present invention uses a camshaft to toggle the solenoid valve, The structure is simple, and the extension and contraction of the drive rod can be reliably realized, so that under the control of the control component, under the specific working conditions of the engine, the axial movement control of the camshaft can be effectively realized through the drive rod. The track groove on the camshaft cooperates to realize the switching of high and low cams and improve the overall performance of the engine.

The invention relates to a repeated locking and releasing mechanism, in particular to a linkage type space repeated locking and releasing mechanism. The linkage type space repeated locking and releasing mechanism aims at solving the problem that reliability and controllability of an existing locking and releasing mechanism in the locking process are poor. The linkage type space repeated locking and releasing mechanism comprises a repeatable locking and releasing mechanism and a linkage driving mechanism. The repeatable locking and releasing mechanism comprises a locking mechanism and a locked assembly. The locking mechanism comprises a connection rod, a rocker connection rod shaft, a rocker, a lock hook rocker shaft, a lock hook, a locking shell, a bearing base, a worm, a worm gear, a first transition gear, a first transition gear shaft, a second transition gear shaft, a second transition gear, a crank gear, a crank connection rod shaft, a rocker shaft and a crank gear shaft. The linkage type space repeated locking and releasing mechanism is used in the aerospace field.

The present invention proposes a flywheel mechanism for a strap connection and unlocking device, which is characterized by comprising: a left casing, a right casing, a bearing, a flywheel, a left-hand screw, a right-hand screw, a loading nut, a platform support, and a separation nut , Double-ended screw, plunger, bayonet, first shaft, mounting seat, flywheel, left-handed screw, right-handed screw, and loading nut are tape connectors; plunger and bayonet are tape connection unlocking pieces; When inserted into the flywheel slot, the strap connection is realized. When the pin rotates out of the slot, the circumferential constraint of the flywheel is released, the flywheel rotates relative to the left and right screws, and the left and right screws are pulled out from the flywheel to unlock the strap. The invention adopts the flywheel to rotate and unlock instead of the explosive bolt to unlock, which can prolong the unlocking time of the strap and realize the slow release of the pre-tightening force of the strap. The unique unlocking technology can greatly reduce the shock caused by the unlocking of the strap.

The invention relates to a waterproof and shockproof structure comprising a first housing and a second housing. The first housing includes a first bottom case and a first outer casing that is made of flexible materials and covers the first bottom case; and a groove is arranged at the first bottom case. The second housing includes a second bottom case and a second outer casing that is made of flexible materials; the second outer casing is provided with a protruding structure and covers the second bottom case and the second outer casing and the second bottom case are formed into an integrated mode. The protruding structure of the second outer casing and the groove of the first bottom case are in an interference fit relation, so that the first housing and the second housing are assembled together. Because the first outer casing and the second outer casing are made of the flexible materials, the shockproof function is realized; and on the basis of the interference fit, the waterproof property between the housings is realized. In addition, the invention also relates to a mobile phone based on the structure; and thus the mobile phone has the dual waterproof and shockproof functions.
