The utility model relates to the technical field of automobile door structures, and particularly discloses a rearview mirror installation structure and a vehicle, the rearview mirror installation structure comprises a rearview mirror installation reinforcing plate assembly, a rearview mirror lining, a door and window frame and a door inner plate, and specifically, the door and window frame is fixed on the door inner plate to enhance the overall base layer rigidity of a rearview mirror area. The rearview mirror installation reinforcing plate assembly is arranged on the outer side, away from the door inner plate, of the door and window frame and fixed to the door and window frame, and the rigidity of a rearview mirror installation point is improved. Furthermore, a cavity is formed between the rearview mirror installation reinforcing plate assembly and the door inner plate, the rearview mirror lining is arranged in the cavity, the rearview mirror lining is fixedly connected with the door and window frame and the rearview mirror installation reinforcing plate assembly, and the rearview mirror is installed on the outer side wall, back to the door and window frame, of the rearview mirror installation reinforcing plate assembly. The door and window frame is connected with the rearview mirror installation reinforcing plate assembly through the rearview mirror lining, and the rigidity performance of rearview mirror installation points is further improved.

The invention discloses a smoke bomb base for a combat vehicle turret cover and a combat vehicle turret cover, comprising a smoke bomb base shell matched with a smoke bomb base accommodating cavity reserved on the turret cover, an opening being arranged on one side of the smoke bomb base shell, a first smoke bomb placement tube, a second smoke bomb placement tube and a third smoke bomb placement tube with openings upward being arranged on a bottom plate in the smoke bomb base shell, and the projections of the first smoke bomb placement tube, the second smoke bomb placement tube and the third smoke bomb placement tube along their respective axis directions are not on the top plate of the smoke bomb base shell; the axis of the first smoke bomb placement tube, the axis of the second smoke bomb placement tube and the axis of the third smoke bomb placement tube and the bottom plate of the smoke bomb base shell form angles of 87.3° to 87.7°, 86.6° to 87.0° and 79.9° to 81.3° respectively. The invention can solve the problem that the launch angle and azimuth angle cannot meet the launch requirements when the smoke bomb is launched.

This invention provides a drive device for a continuum robot, comprising a base; multiple fixed pulleys and spaced rope perforation plates; a variable stiffness mechanism supported on the base and located between adjacent rope perforation plates, which has M variable stiffness cams arranged along a common first axis. Each variable stiffness cam changes the tension of the corresponding drive rope after passing through the fixed pulleys by changing its own radius; multiple cam mechanism assemblies are respectively arranged between two adjacent rope perforation plates, and each cam mechanism assembly has M drive cams arranged along a common second axis. Each drive cam has a follower on its upper part, and each drive rope passes through the top of a corresponding follower. During the rotation of the drive cam, the bottom end of the follower makes rolling contact with the top end of the drive cam, and the follower moves radially along the drive cam by changing the radius of the drive cam itself, thereby changing the length of the drive rope. This invention can reduce the number of drive motors, simplify control, and improve the stiffness of the continuum robot.

The utility model belongs to the technical field of air bearings, and particularly relates to an air bearing and a rotating machine. The air bearing comprises an installation part and a cooling pipe, the installation part is used for installing a supporting part capable of supporting a top foil, the supporting part is made of shape memory alloy, the cooling pipe is correspondingly arranged on one side of the installation part and can penetrate through the supporting part, and multiple sets of cooling holes distributed at intervals in the axial direction of the cooling pipe are formed in the cooling pipe. Each group of cooling holes comprises a plurality of sub-holes which are distributed at intervals in the circumferential direction of the cooling pipe, and in the arrangement direction between the mounting piece and the cooling pipe, the sub-holes located in the side, close to the mounting piece, of the cooling pipe and the mounting piece are arranged in a staggered mode. By adopting the air bearing provided by the embodiment of the invention, the cooling gas can be dispersed more uniformly, so that the supporting piece is uniformly cooled, the supporting piece is recovered to the original shape to stably support the top foil, and the rigidity performance of the air bearing is optimized.

The utility model belongs to vehicle engineering technical field, concretely is a kind of armored vehicle turret posture control mechanism, including front cover;The front cover end portion is rigidly connected with shell;The front cover end portion is rigidly connected with back cover;The shell lateral wall is equipped with aviation plug;The input shaft is rotatably connected in the middle part of the front cover and back cover, and the input shaft outer wall is equipped with rotating handle;Its characterized in that: the shell inner wall is rigidly connected with boss;Multiple sets of connecting holes are arranged in the middle part of the shell;The middle part of the shell is equipped with mounting hole, and plug is installed in the inner wall of mounting hole;Multiple sets of first through holes are arranged in the bottom of the shell;The shell inner part is three functional areas, uses electric signal as the feedback mode of turret posture control mechanism, removes the transmission and the large amount of mechanical transmission components, such as speed reduction mechanism, etc. in the traditional structure using gear, and the present mechanism uses modularization package, so it is small and exquisite compact.
