It should be noted that: like reference numerals and letters denote like items in the following figures, and thus once an item is defined in one figure, no further discussion thereof is necessary in subsequent figures.

According to an embodiment of the application, an escape ladder device 04 is provided. The device comprises:

A base 042, wherein the base 042 is provided with a connecting part which is suitable for being connected with equipment to be installed in a rotating way;

An escape ladder body 045, wherein the escape ladder body 045 is arranged on the base 042, and the escape ladder body 045 can be stored and unfolded;

The connecting rod mechanism is arranged on the base 042 and is connected with the escape ladder body 045; and

The driving mechanism is suitable for being connected with equipment to be installed at one end, the other end of the driving mechanism is connected with the connecting rod mechanism, and the driving mechanism can drive the base 042 to rotate relative to the connecting part and drive the connecting rod mechanism to move, so that the connecting rod mechanism drives the escape ladder body 045 to be unfolded.

In particular, as shown in fig. 1, 2, 5, the device to be installed may be, but is not limited to, a vehicle, such as a vehicle, a watercraft, an aircraft, etc. For example, the device to be installed comprises a floor 01. The floor 01 is provided with an opening 011. The escape apparatus 04 is provided at the opening 011. The escape ladder device 04 is used for emergency escape of personnel of the equipment. The base 042 is used for bearing the escape ladder body 045, the link mechanism, the driving mechanism and the like. The escape ladder body 045 is mounted on the equipment to be mounted through the base 042. For example, the base 042 has a plate shape. The cross-sectional shape of the base 042 may be, but is not limited to, rectangular, circular, oval, triangular, etc. The material of the base 042 may be, but is not limited to, metal, plastic, wood, ceramic, etc. For example, the connection includes a hinge base 041, the hinge base 041 having a rotational axis. The hinge base 041 is mounted on a side of the base 042. The base 042 is rotatable about the rotation axis.

The escape ladder body 045 is a folding escape ladder or a telescopic escape ladder. The escape body 045 has a pedal 044 or foot rest lever to facilitate walking of a person.

The linkage includes at least one link. For example, one end of the linkage is rotatably coupled to the base 042. The other end of the connecting rod mechanism is rotationally connected to the escape ladder body 045. Of course, if the escape ladder body 045 is flexible, the other end of the linkage may also be fixedly connected to the escape ladder body 045.

The driving mechanism is used for applying acting force to the connecting rod mechanism so as to facilitate the unfolding and the storage of the base 042 and the escape ladder body 045. The drive mechanism may be, but is not limited to, an electric push rod 043, a pneumatic push rod, or the like. One end of the driving mechanism is rotationally connected to the equipment to be installed, and the other end of the driving mechanism is rotationally connected to the connecting rod mechanism.

Upon deployment, the drive mechanism expands, thereby exerting a force on the linkage mechanism. The drive mechanism does not act directly on the escape ladder body 045, but on the linkage mechanism. In the first stage, since the driving mechanism needs to overcome the gravity of the escape ladder body 045 and the like, the linkage mechanism does not swing, the escape ladder body 045 does not spread, and the driving mechanism pushes the base 042 to rotate around the connecting part through the linkage mechanism so as to spread the base 042 relative to the equipment to be installed. In the second stage, the driving mechanism continues to extend, and drives the connecting rod mechanism to swing, and the connecting rod mechanism drives the escape ladder body 045 to expand.

During storage, in the first stage, the driving mechanism contracts, the driving mechanism drives the connecting rod mechanism to reversely swing, and the connecting rod mechanism drives the escape ladder body 045 to contract; in the second stage, the drive mechanism continues to retract, and the linkage mechanism swings to engage the base 042, and is no longer movable, as the escape body 045 has contracted to its shortest. At this time, the base 042 swings reversely around the connecting portion under the drive of the driving mechanism, so as to be accommodated on the equipment to be mounted.

In the embodiment of the application, the base 042 can be opened and closed and the escape ladder body 045 can be unfolded and stored by one driving mechanism, so that the escape ladder device 04 has a simple, compact and small structure.

In addition, the escape ladder device 04 realizes the opening and closing of the base 042 and the unfolding and containing of the escape ladder body 045 at different stages, and the two actions cannot interfere.

Furthermore, the escape ladder device 04 can also be operated manually.

In one example, the escape apparatus 04 further comprises a handrail mechanism 046, the handrail mechanism 046 being connected to the escape body 045, the handrail mechanism 046 being retractable with the escape body 045.

In this example, as shown in fig. 1, 2, and 5, the armrest mechanism 046 has a telescopic structure. The armrest mechanism 046 includes a plurality of armrest sleeves 0462 that are nested together. For example, the innermost and outermost handrail barrels 0462 are connected to the escape body 045 by handrail mounting brackets 0461, respectively. The armrest mechanism 046 is located on one side of the escape ladder body 045 perpendicular to the deployment direction. The armrest mechanism 046 expands with the expansion of the escape ladder body 045 and contracts with the storage of the escape ladder body 045.

In this example, the extension and retraction of the escape body 045 and the armrest mechanism 046 can be achieved by one drive mechanism. This results in a more compact construction of the escape ladder assembly 04.

In other examples, the armrest mechanism 046 may also take a folded configuration.

Of course, the specific configuration of the armrest mechanism 046 is not limited to the above-described embodiment, and may be set as desired by those skilled in the art.

In one example, one end of the linkage is rotatably connected to the base 042 and the other end of the linkage is rotatably connected to the escape ladder body 045.

In this example, as shown in fig. 1 and 2, one end of the link mechanism is directly or indirectly hinged to the base 042 through a rotation shaft, and the other end is directly or indirectly hinged to the escape ladder body 045 through a rotation shaft. The rotational connection provides activity for the swinging of the linkage.

Of course, in the case of a flexible linkage, the linkage may also be fixedly connected to the base 042 and the escape body 045.

In one example, the other end of the drive mechanism is rotatably coupled to the linkage mechanism.

As shown in fig. 1 and 2, two ends of the link mechanism are respectively hinged with the base 042 and the escape ladder body 045. The other end of the driving mechanism is rotationally connected with the position between the two ends of the connecting rod mechanism. For example, the hinge may be directly hinged to the link mechanism, or may be indirectly hinged to the link mechanism.

By changing the position of the connection point between the two ends of the link mechanism, the magnitude of the driving force of the driving mechanism and the adjustment of the installation angle of the driving mechanism can be realized. For example, the closer the connection point is to the base 042, the smaller the moment arm when the driving mechanism is driven, the larger the driving force is required, and the more compact the structure and the smaller the volume of the escape ladder apparatus 04; conversely, the closer the connection point is to the escape ladder body 045, the longer the arm of force when the driving mechanism drives, the smaller the driving force required, the looser the structure of the escape ladder device 04, and the larger the volume.

Of course, those skilled in the art can select the location of the connection point according to actual needs, and the present invention is not limited thereto.

In one example, the distance from the base 042 to the connection point of the drive mechanism to the linkage is greater than the distance from the base 042 to the connection point of the drive mechanism to the device to be installed.

As shown in fig. 1, 2, 6 and 7, an opening 011 is provided in the member to be mounted. Base 042 is hinged to one side of opening 011 by hinge base 041. The base 042 can rotate about point O. One end of the driving mechanism is hinged with the middle part of the connecting rod mechanism through a lock pin 0432 and a pin shaft 0431, and the hinge point is C. The other end of the driving mechanism is hinged with the side wall of the opening 011, and the hinge point is A. One end of the connecting rod mechanism is hinged with the base 042, and the hinge point is B. The other end of the connecting rod mechanism is hinged with the escape ladder body 045, and the hinge point is E. The hinge point of the other end of the escape ladder body 045 is H. When the base 042 rotates downwards, the distance of AB will increase, the angle of the angle ACB will increase, the angle of the angle ACE will decrease, the distance of AE will decrease, and the distance of HE will decrease. However, in the stored state, the distance of HE has reached a minimum value and is not reduced any more.

In a first phase, when the escape apparatus 04 is unfolded, the driving mechanism, such as the electric push rod 043, is extended, the base 042 is first rotated around the O-point until the slider 0422 connected to the limit rod 049 described below is moved to the end, such as the left end of the chute 0423, and the base 042 stops moving. At this stage, the linkage does not rotate about the hinge point B and the escape body 045 does not unfold. Because the action needs to overcome the resistance of the escape ladder body 045 such as gravity and the like and needs the electric push rod 043 to provide certain thrust, the rotation of the base 042 around the O point does not need to overcome the gravity to do work, gravitational potential energy of the base 042, the escape ladder body 045 and the like can be converted into kinetic energy of the base 042 which rotates around the O point, the electric push rod 043 does not need to provide thrust or small thrust, and therefore the electric push rod 043 can preferentially perform the rotation of the base 042 around the O point until the sliding block 0422 connected with the limiting rod 049 moves to the end point. At this time, the opening 011 is opened.

In the second stage, the electric push rod 043 continues to extend, at this time, the link mechanism rotates around the point B, the distance of HE increases, and the escape ladder body 045 expands until the ladder leg 047 described below abuts against the escape passage.

In one example, the linkage mechanism includes two first links 048, one end of each first link 048 is rotatably connected to the base 042, the other end of each first link 048 is rotatably connected to the escape body 045, and the escape body 045 is located between the two first links 048.

As shown in fig. 1 to 6, for example, the material of the first link 048 may be, but not limited to, metal, wood, ceramic, plastic, etc. The two first links 048 are arranged in parallel. One end of the first connecting rod 048 is hinged with the base 042 at the point B, and the other end is hinged with the escape ladder body 045 at the point E. The E point is positioned at the middle position of the retraction direction of the escape ladder body 045, and the escape ladder body 045 is hinged between the two first connecting rods 048. The two first connecting rods 048 are respectively hinged with the middle position of the escape ladder body 045. This way makes two first connecting rods 048 both drive the escape ladder body 045 to be unfolded and stored, which makes the unfolding and storage of the escape ladder body 045 smoother.

Further, a cross bar 0481 is connected between the two first links 048. The cross bar 0481 may be made of, but is not limited to, metal, wood, ceramic, plastic, etc. The cross bar 0481 is connected with the two first connecting rods 048 in a welding, bolting, riveting, clamping and other mode. One end of the electric push rod 043 is hinged to the middle of the cross rod 0481. The cross rod 0481 can improve the structural strength of the two first connecting rods 048 and ensure the synchronization of the actions of the two first connecting rods 048 on one hand; on the other hand, an installation space can be provided for the articulation of the electric putter 043.

In one example, a fixed rod is provided on the base 042, and the fixed rod is rotatably connected with the link mechanism.

As shown in fig. 4 and 5, the fixing rod is fixed to the base 042 by welding, clamping, or the like. The fixing rod protrudes from the base 042, which facilitates the articulation of the first link 048 with the base 042. For example, the fixing rod is a limiting tube 0421. The material of the limiting tube 0421 may be, but is not limited to, metal, plastic, ceramic, etc. The limiting tube 0421 is a square tube, a round tube or the like. The number of the limiting pipes 0421 is two. The two limiting pipes 0421 are arranged on the base 042 in parallel. One end of the limiting tube 0421 is hinged with one end of the first connecting rod 048.

Of course, the structure of the fixing lever is not limited to the above-described embodiment, and a person skilled in the art may set it according to actual needs.

In one example, the escape apparatus 04 further comprises a limiting mechanism, one end of which is connected to the base 042, the other end of which is adapted to be connected to the device to be installed, the limiting mechanism being adapted to define the opening angle of the base 042.

As shown in fig. 4 and 5, the stopper mechanism is, for example, a stopper rod 049, a stopper rope, or the like. For example, one end of the stopper rod 049 is connected to the floor 01 of the apparatus to be installed, and the other end is connected to the base 042. The limiting rod 049 can limit the maximum angle of the base 042 unfolding, so that accidents caused by overlarge base 042 unfolding are avoided. The maximum angle of the base 042 unfolding is controlled by adjusting the length of the limiting rod 049.

In one example, the fixed rod is provided with a chute 0423, the limit mechanism comprises a limit rod 049, one end of the limit rod 049 is slidably connected with the chute 0423, and the other end of the limit rod 049 is suitable for being rotatably connected with equipment to be installed.

As shown in fig. 4 to 6, a chute 0423 is formed on the wall of the limiting tube 0421. One end of the limiting rod 049 is provided with a sliding block 0422, and the connection point of the limiting rod 049 and the sliding block 0422 is a G point. The slider 0422 is positioned in the chute 0423 and slides along the chute 0423. The other end of the limit rod 049 is hinged with the side wall of the opening 011 of the floor 01 at the point F. The stop bar 049 forms a stop fit with the stop tube 0421, thereby limiting the maximum angle of deployment of the base 042, e.g. the slide 0422 sliding to the left end of the chute 0423. When stored, the slider 0422 slides to the right end of the chute 0423.

Further, the stopper rod 049 includes a rod body and ball bearings at both ends. The rod body is in threaded connection with the ball bearing, and the length of the limiting rod 049 can be adjusted in the mode, so that the adjustment of the maximum angle of the bottom plate unfolding is easy.

In one example, the escape body 045 comprises a folding escape as previously described. As shown in fig. 1 and 5, the folding escape ladder has the characteristics of compact structure, small volume and easy unfolding and storage.

In one example, the folding escape ladder includes a linkage assembly and a pedal 044, the linkage assembly being coupled to the pedal 044.

As shown in fig. 4 and 5, the linkage assembly includes a plurality of links hinged together. The plurality of links form a collapsible structure. The connecting rod assembly is rotatably connected with the pedals 044 so that a plurality of pedals 044 are stacked together when stored and form a multi-stage step when unfolded. The structure of the link assembly, the number of pedals 044, etc. may be set as desired by those skilled in the art.

In one example, the linkage assembly includes a central structure including a plurality of groupings of links pivotally connected together in a first direction, each of the groupings including two second links 0451 cross-hinged at a central portion.

As shown in fig. 5, each linkage includes two second links 0451. The middle portions of the two second links 0451 are hinged together to form a cross-over structure. The cross structure can be unfolded and stored. The ends of the two second connecting rods 0451 of the two adjacent connecting rod groups are respectively hinged together, so that different connecting rod groups can be unfolded and stored simultaneously. The number of the linkage groups can be set according to actual needs by those skilled in the art. The middle structure has the advantages of simple structure, firmness and good stability.

Further, the two second links 0451 of each linkage are S-shaped bars. The inner arcs of the two second connecting rods 0451 are opposite and are hinged in a crossed mode, compared with the mode that the second connecting rods 0451 are straight rods, the S-shaped rods can increase the length of the escape ladder body 045 in the unfolded state, and the height of the escape ladder body 045 in the storage state is reduced. This arrangement makes the escape ladder body 045 more compact.

Of course, the structure of the second link 0451 is not limited thereto, and a person skilled in the art may set according to actual needs.

In one example, the folding escape ladder further comprises a first end structure, the first end structure comprises a third connecting rod 0452 and a fourth connecting rod 0453, one end of the third connecting rod 0452 is rotatably connected with the middle part of the fourth connecting rod 0453, the other end of the third connecting rod 0452 is rotatably connected with one second connecting rod 0451 at one end of the middle structure, one end of the fourth connecting rod 0453 is rotatably connected with the other second connecting rod 0451 at one end of the middle structure, and the other end of the fourth connecting rod 0453 is rotatably connected with the base 042.

As shown in fig. 2 and 5, in this example, a connecting rod is provided on the base 042, and one end of the fourth connecting rod 0453 is hinged to the connecting rod, and the other end is hinged to one second connecting rod 0451 of the link group on the left side of the middle structure. One end of the third connecting rod 0452 is hinged with the middle part of the fourth connecting rod 0453, and the other end is hinged with the other second connecting rod 0451 in the connecting rod group at the left side of the middle part structure. The fourth link 0453 is identical to the second link 0451 in structure, for example, is an S-shaped lever. The third link 0452 is an arcuate bar, e.g., the third link 0452 is half of the fourth link 0453. The arrangement of the fourth connecting rod 0453 and the third connecting rod 0452 facilitates connection of the connecting rod assembly and the base 042, improves structural strength of the connecting rod assembly, and can drive the middle structure to be unfolded and stored synchronously.

Of course, the first end structure is not limited to the above-described embodiment, and a person skilled in the art may set it according to actual needs.

In one example, the folding escape ladder further comprises a second end structure comprising two fifth links 0454 rotatably connected together at one end, one of the two fifth links 0454 being rotatably connected to one of the second links 0451 at the other end of the central structure, the other of the two fifth links 0454 being rotatably connected to the other of the second links 0451 at the other end of the central structure.

As shown in fig. 5, the fifth link 0454 is an arc-shaped lever. Preferably, the fifth link 0454 has the same structure as the third link 0452. One end of each of the two fifth links 0454 interfaces with two second links 0451 of the linkage on the right side of the central structure. The other ends of the two fifth links 0454 are hinged together. The two fifth connecting rods 0454 enable the escape ladder body 045 to form a closed structure, so that connection with other components and storage of the escape ladder body 045 are facilitated.

Furthermore, the closed structure has high structural strength and stability.

Of course, the second end structure is not limited to the above-described embodiment, and may be provided according to actual needs by those skilled in the art.

In one example, the escape ladder apparatus 04 further comprises a support structure, which is rotatably connected to the connecting shafts of the two fifth links 0454.

As shown in fig. 1 and 5, the support structure is used to support the deployed escape ladder body 045. Support structures such as ladder feet 047. The two fifth links 0454 are hinged together by a connecting shaft. The ladder leg 047 is hinged with the connecting shafts of the two fifth connecting rods 0454. The articulated mode makes ladder foot 047 can be according to different ground adjustment contact position and angle to make ladder foot 047 more firm to the support of escape ladder body 045.

Of course, the support structure is not limited to the above embodiment, and those skilled in the art can set it according to actual needs.
