The invention discloses anautomatic blackboard dust collection device, which comprises a box, wherein the box is arranged below a blackboard; an upper panel of the box is provided with a through hole for dust to passthrough; at least two fans are fixedly arranged below the upper panel; a dust guide plate is arranged below the fans; and one end of the dust guide plate is provided with a dust collection box. The upper body structure of the device consists of three parts, i.e., silent fans, a supporting frame and a wind direction plate; the silent fans blow downwards to form an air curtain; the silent fans and the wind direction plate are supported by the supporting frame; the dust moves downwards close to the blackboard through the wind direction plate; and the lower body structure of the device comprises a dust collection device, an air guide plate, the dust guide plate, the dust collection box, the upper panel and a box. The box is used for fixing all lower body structural components, and placing a photoelectric switch and a circuit board in a control system. The device is only required to be arranged on upper and lower wall bodies of the blackboard, the blackboard is not required to be modified, the device is simple and convenient, and the cost is saved.

Provided is a lower vehicle body structure that improves the support rigidity of a vehicle body floor for supporting seat rails. The lower vehicle body structure of the present invention includes: a vehicle body floor (2); a first floor beam (14) extending along the vehicle width direction and having a closed cross-section structure; a second floor beam (16) parallel to the vehicle front and rear direction. The first floor beams (14) are arranged at intervals and have a closed cross-sectional structure along the vehicle width direction; the side beams (4) are arranged at the ends of the vehicle body floor (2) in the vehicle width direction and along the vehicle front-rear direction extending and having a closed cross-sectional structure; the floor frame (12), which is arranged on the inner side in the vehicle width direction compared with the side beam (4), extends along the vehicle front-rear direction and has a closed cross-sectional structure; and the mounting parts (65, 66, 68, 69), for installing the seat to the vehicle body. Mounting members (65, 66, 68, 69) are fixed to the edge beams (4), the first floor beam (14), and / or said second floor beam (16).

A roof structure corner connector is disclosed. A vehicle body includes a longitudinal roof spine and a plurality of roof rails extending transversely from the roof spine to a plurality of pillars extending upwardly from a lower body structure. The roof rail and the pillars are connected by corner connectors that include male ends that are received in openings defined at the outer ends of the roof rail. The opening is defined in the bottom wall of the outer end of the roof rail and is assembled on and supported by the insertion end. An opening in the bottom wall of the roof rail is defined between the two side walls.

The present invention relates to a lower body structure for a vehicle, which includes a floor (1) of a spare tire pan (1a) depressing downwards, a pair of rear carlings (2a, 2b) disposed on the left / right side of the floor (1) and extending along the front / rear direction of the vehicle body, a beam (3) bridged between the pair of rear carlings (2a, 2b) in the front part of the spare tire pan (1a), a sub frame (4) at least a part of which is supported by a support part (5) of the rear side carlings (2a, 2b) at a rear position of the beam (3), and a junction panel (7) bridged between the end neighborhood of the beam (3), and the support part (5) of the sub frame (4) on the rear carlings (2a, 2b) and the spare tire pan (1a). By using the present invention, the simple structure can be used to efficiently improve the support rigidity of the sub frame by the support part, even layout is restricted by arrangement of the spare tire pan.

The invention discloses a human walking simulated plate carrying robot, comprising an upper body structure, a waist board, a lower body structure and a double-stable meal delivery device. The upper body structure is a frame type structure, and comprises a main frame. The main frame comprises a head portion, a shoulder portion and a thoracico-abdominal portion. The double-stable meal delivery device comprises a meal delivery bottom plate. A main container having an arched vertical section is arranged on the meal delivery bottom plate. A lead block is fixedly connected to the bottom of an inner cavity of the main container, and the center of gravity of the lead block is located right above a first ball. A water holding plate is arranged in the inner cavity of the main container above the lead block, and hermetically connected to the inner wall of the main container. The center of the water holding plate is upwardly connected with an elastic expansion link, and the top end of the elastic expansion link is fixedly connected to a second ball. The water holding plate and the main container define a water tank. The water tank is filled with water, and a tableware tray floats on the water, and comprises a disc-shaped tray bottom plate. The human walking simulated plate carrying robot is capable of simulating human walking, and also capable of avoiding unstable meal delivery, and is simple in structure and relatively low in manufacturing cost.
