Embodiment 1

[0031] A passive full-range locking device based on direction control, including an inner sleeve 1 connected with the door transmission part, a one-way clutch 2, a sleeve 3 with an end sprocket, and a shaft designed integrally with the drive shaft 7 To the cam 4, a follower 5, an annular spring 6, an end sprocket 8, a cylindrical spring 9, a housing 10, and a torsion spring 11. The inner sleeve 1 is installed in the one-way clutch 2 and is nested with the axial cam 4 in the idle motion. The fixed side (outer shell) of the one-way clutch 2 is fixedly connected with the sleeve 3. The toothed plate of the sleeve 3 and the end toothed plate 8 paired clutch, the pin 12 on the axial cam 4 is inserted into the opening of the cage 51 of the follower 5 to realize the nesting of the two rotating idle distances, a group of rollers 52 roll on the corresponding step ramp of the axial cam 4, and the circular The spring 6 is installed in the groove of the cage 51, and the elastic force of th...

Embodiment 2

[0035]A passive full-range locking device based on direction control, including an inner sleeve 1 connected with the door transmission part, a one-way clutch 2, a sleeve 3 with end toothed discs, an axial cam 4, and a driven Part 5, a ring spring 6, a drive shaft 7, an end sprocket 8, a cylindrical spring 9, a housing 10, and a torsion spring 11. The inner sleeve 1 is installed in the one-way clutch 2 and is nested with the drive shaft 7 in idle motion. The fixed side (outer shell) of the one-way clutch 2 is fixedly connected with the sleeve 3, and the toothed plate of the sleeve 3 is paired with the end toothed plate 8. Clutch, the axial cam 4 is vacantly sleeved on the drive shaft 7, and a pin 12 is inserted into the opening of the cage 51 to realize the nesting of the two rotating idle distances, and a set of rollers 52 roll on the corresponding step ramp of the axial cam 4, The cage 51 of the follower 5 is fixedly connected with the end sprocket 8, and the ring spring 6 is...

Embodiment 3

[0038] A passive full-range locking device based on direction control, including an inner sleeve 1 connected with the door transmission part, a one-way clutch 2, a sleeve 3 with a cylindrical toothed disc, a radial cam 4, and a driven Part 5, a ring spring 6, a drive shaft 7, a cylindrical spring 9, a housing 10, a torsion spring 11, and a stop pin 13. The inner sleeve 1 is installed in the one-way clutch 2 and is nested with the driving shaft 7 in idle motion.

Abstract

The invention discloses a passive whole-process locking device based on direction control. The passive whole-process locking device comprises an inner sleeve connected with a door transmission component, a one-way clutch allowing the inner sleeve to freely rotate in the door closing direction, a sleeve fixedly connected with a shell of the one-way clutch and provided with meshing teeth, a drivingpiece provided with a rated rotation idle stroke with the inner sleeve, a retainer capable of being separated from and combined with the sleeve, one or a set of elastic pieces acting on the retainer to enable the retainer to tend to be meshed with the sleeve, and a shell supporting the sleeve, the driving piece and other necessarily arranged base bodies in a rotating mode; and the passive whole-process locking device further comprises a cam, a driven piece matched with the cam to form a cam mechanism, and one or a set of moment generating pieces, wherein a rated rotation idle stroke is arranged between the cam and the driven piece. The passive whole-process locking device based on the direction control thoroughly overcomes the principle defects of an existing device, and the overall structure has the advantages of being compact and concise.

Description

technical field [0001] The invention relates to the technical field of door leaf locking devices, in particular to a passive full-range locking device based on direction control. Background technique [0002] The full-range locking device is an important type of door system lock device in the transportation field. Its full-range one-way locking feature enables the door to obtain some special functions and performances. According to whether the full-range locking device has independent control power components, it can be divided into "active full-range locking device" and "passive full-range locking device". The "active full locking device" has a complex structure, large volume, high cost, bulkiness and high energy consumption, while the "passive full locking device" has a compact structure, low cost, light weight and no energy consumption. [0003] Patent application 96101108.4 discloses a driving device, which is different from ordinary one-way devices in that it has a var...
