The invention discloses a reinforced transfer box. The reinforced transfer box comprises a packaging box body (1) and is characterized in that an outer protective layer (2) is arranged outside the transfer box body (1) in a sleeving mode; an inner buffer layer (3) is integrally arranged on the outer protective layer (2) and is composed of a plurality of hollow pillar bodies (4); the upper end of each pillar body (4) is covered with an arc cover (5) which is provided with a small hole (6); the ratio of the aperture of the small holes (6) to the aperture of the pillar bodies (4) is 1:5; the inside of each pillar body (4) is connected with the outside through the corresponding small hole; a soft metal dense net (7) is detachably laid on the inner buffer layer (3). According to the reinforced transfer box, the inner buffer layer capable of slowly releasing gas is adopted, the deformation speed of the pillar bodies is reduced, and the buffering effect is excellent. The soft metal dense net is additionally arranged on the inner buffer layer, so that protection of the inner buffer layer and cleaning of the transfer box are facilitated.

The seat tilting device for side impact collision of passenger cars and the passenger car with the device are installed between the power passage and the B-pillar of the side body of the vehicle body, characterized in that the seat tilting device includes: a tilting flip lever One end is fixed on the vehicle body floor close to the vehicle body power channel, and the other end is fixedly connected to the B-pillars on both sides of the vehicle body and has an inclination angle with the vehicle body floor. In the process of a side collision accident of a car, under the action of the impact force, the B-pillar on the side of the impact will drive the tilting and flipping lever to rotate around the fulcrum on the body floor, and at the same time push the seat and the occupant to tip over, which can prevent the impact on the side B-pillar and the door Direct impact on the occupant's body is beneficial to the full deployment of the side airbags. The tilted flip lever increases the rigidity of the impacted side, which is beneficial to reduce the deformation of the impacted side B-pillar and door, and reduce the deformation speed of the impacted side B-pillar and door. Reduce the personal injury of the occupant in the side collision of the car.

The invention discloses a solar photovoltaic panel safety transport device and relates to the technical field of solar photovoltaic panel production. The solar photovoltaic panel safety transport device includes a movable box, the bottom of the movable box is provided with a rotating roller, the left side of the movable box is fixedly installed with a push handle near the upper end, and the inner wall of the movable box is provided with a fixing mechanism near the top , the bottom of the inner wall of the movable box is provided with a buffer mechanism, the fixed mechanism includes a connecting plate, a contact piece and a fixed plate, the connecting plate is fixedly installed on the inner wall of the movable box near the upper end, and the connecting plate is L-shaped. The solar photovoltaic panel safety transport device is equipped with a fixing mechanism and a buffer mechanism. When the movable box vibrates due to movement, it clamps the inner photovoltaic panel and stops the vibration of the movable panel in contact with the photovoltaic panel quickly, avoiding the vibration of the movable box. The photovoltaic panels on the inside rub against each other and collide, causing damage to the photovoltaic panels.
