Emergency separation cabin door deployment and retraction device

Abstract

The present invention provides an emergency separation hatch door deployment and retraction device, comprising a deployment and retraction mechanism, a synchronous deployment and retraction mechanism and a control device, wherein the power source and the explosive bolt in the deployment and retraction mechanism are electrically connected to the control device, and the synchronous power source and the synchronous explosive bolt in the synchronous deployment and retraction mechanism are electrically connected to the control device. During operation, the deployment and retraction mechanism and the synchronous deployment and retraction mechanism work simultaneously to deploy or retract the hatch door; when the deployment and retraction device fails during deployment or retraction of the hatch door and cannot be deployed or retracted normally, the control device sends an electrical signal to cause the explosive bolt to explode, and the deployment and retraction mechanism stops moving. At the same time, the control device sends an electrical signal to the synchronous power source to cause the synchronous deployment and retraction mechanism to deploy or retract the hatch door, thereby ensuring the normal deployment or retraction of the hatch door and the normal operation of the operation.

Description

Technical Field

[0001] The invention relates to the field of aerospace equipment, and in particular to an emergency separation cabin door deployment and retraction device. Background Art

[0002] Some space vehicles, such as space shuttles, spacecraft, and satellites, have hatch mechanisms. During the in-orbit operation of the vehicle, the hatch needs to be deployed and retracted so that the internal load can complete the task. The mechanism that overcomes the hatch resistance torque and performs the hatch deployment and retraction action is the deployment and retraction mechanism. At present, the hatch deployment and retraction mechanism has a stuck failure and cannot be separated in an emergency, resulting in the hatch being unable to be retracted or deployed, and the reliability is low.

[0003] In order to solve the above problems, the present invention provides an emergency separation cabin door deployment and retraction device. Summary of the invention

[0004] In order to solve the problems in the prior art, the present invention provides an emergency separation cabin door deployment and retraction device.

[0005] The technical solution of the present invention is as follows:

[0006] An emergency separation cabin door deployment and retraction device, comprising a deployment and retraction mechanism, a synchronous deployment and retraction mechanism and a control device;

[0007] The stowage and unfolding mechanism comprises a power source, a crank, a connecting rod mechanism and a mounting seat, wherein the power source is mounted on the cabin body, the power source is drivingly connected to the crank, one end of the crank is hinged to the connecting rod structure, one end of the connecting rod mechanism is hinged to the mounting seat, and the other end is hinged to the cabin door, an explosive bolt is provided on the connecting rod mechanism, the explosive bolt is electrically connected to the control device, and the mounting seat is mounted on the cabin body;

[0008] The synchronous extension and retraction mechanism comprises a synchronous power source, a synchronous crank, a synchronous connecting rod mechanism and a synchronous mounting seat, wherein the synchronous power source is installed on the cabin body, the synchronous power source drives and connects the synchronous crank, one end of the synchronous crank is hinged to the synchronous connecting rod structure, one end of the synchronous connecting rod mechanism is hinged to the synchronous mounting seat, and the other end is hinged to the cabin door, a synchronous explosive bolt is provided on the synchronous connecting rod mechanism, the synchronous explosive bolt is synchronously connected to the electrical device, and the synchronous mounting seat is installed on the cabin body;

[0009] The control device is electrically connected to the power source and the synchronous power source, and the control device controls the power source or the synchronous power source to start.

[0010] In the present technical solution, both the unfolding and retracting mechanism and the synchronous unfolding and retracting mechanism are used for unfolding or retracting the hatch. In the normal state, the unfolding and retracting mechanism and the synchronous unfolding and retracting mechanism work simultaneously and act on the hatch together to unfold or retract the hatch. When the unfolding and retracting mechanism is stuck, the control device sends an electrical signal to cause the explosive bolt to explode, and a break occurs in the unfolding and retracting mechanism, which no longer participates in the unfolding or retracting of the hatch. At this time, the synchronous unfolding and retracting mechanism continues to unfold or retract the hatch, ensuring that the unfolding or retracting of the hatch can work normally and is not affected. Similarly, when the synchronous unfolding and retracting mechanism is stuck, the unfolding and retracting mechanism continues to unfold or retract the hatch, ensuring that the unfolding or retracting of the hatch can work normally and is not affected.

[0011] On the basis of the above solution and as a preferred solution of the above solution: the connecting rod mechanism includes a first connecting rod, a second connecting rod and a third connecting rod;

[0012] The second connecting rod has a first connecting portion and a second connecting portion at a certain angle, the end of the first connecting portion has a first left clamping plate and a first right clamping plate arranged on both sides of the mounting seat, the first rotating rod passes through the first left clamping plate, the mounting seat and the first right clamping plate in sequence, and one end of the first rotating rod is fixedly connected to the first left clamping plate, and the other end is fixedly connected to the first right clamping plate, the mounting seat is provided with a first hinge hole for the first rotating rod to pass through, and the end of the second connecting portion is hinged to the third connecting rod;

[0013] One end of the first connecting rod is fixedly connected to the crank, and the other end is hinged to the first connecting part;

[0014] A door connecting seat is provided between the third connecting rod and the door, the door connecting seat is fixed on the door, and the third connecting rod and the door connecting seat are hingedly connected.

[0015] In the present technical solution, a specific structure of a connecting rod mechanism is disclosed. When the deployment mechanism deploys or retracts the hatch, the motor drives the crank to move through the reducer, and the crank drives the first connecting rod to move up or down. The first connecting rod enables the hatch to deploy or retract through the second connecting rod and the third connecting rod.

[0016] On the basis of the above scheme and as a preferred scheme of the above scheme: the first connecting rod is provided with an explosive bolt.

[0017] In the technical solution, the specific installation position of the explosive bolt is disclosed. When the hatch of the deployment and retraction mechanism is opened or closed, the explosive bolt explodes, causing the first screw to break and the deployment and retraction mechanism to stop working.

[0018] On the basis of the above solution and as a preferred solution of the above solution: the stowage mechanism further includes a shielding component;

[0019] The shielding assembly further includes a shielding frame and a limiting mechanism. The shielding frame is fixed to the cabin body through a connecting plate. The top of the shielding frame is open. The limiting mechanism is installed on the top of the shielding frame to limit the movement of the connecting rod mechanism after the explosion of the explosive bolt.

[0020] In the technical solution, the connecting rod mechanism is separated from the crank after the explosion of the explosive bolt, and the separated connecting rod mechanism enters the shielding frame through the limiting mechanism to avoid affecting the synchronous deployment and retraction mechanism to deploy or retract the hatch.

[0021] On the basis of the above scheme and as a preferred scheme of the above scheme: the limiting mechanism includes a first limiter and a second limiter with the same structure, and the first limiter and the second limiter are respectively installed on the top of the two side plates of the shielding frame;

[0022] The first limiter includes a limit seat, a limit plate, a rotating shaft and a torsion spring installed on the side panel, the rotating shaft is installed in the limit seat, one end of the limit plate is fixedly connected to the rotating shaft, the torsion spring is sleeved on the rotating shaft, the first pin of the torsion spring is connected to the limit plate, and the second pin of the torsion spring is fixed in the limit seat.

[0023] In this technical solution, a specific structure of a limiting mechanism is provided. Under the action of the explosive force of the explosive bolt, the connecting rod mechanism squeezes the limiting plate into the shielding frame. Under the action of the torsion spring, the limiting plate returns to its initial state, limiting the connecting rod mechanism to be located in the shielding frame.

[0024] On the basis of the above scheme and as a preferred scheme of the above scheme: a weight-reducing hole is provided on the second connecting portion, and a connecting angle between the weight-reducing hole and the second connecting portion is an arc angle.

[0025] In the technical solution, the weight-reducing hole on the second connecting part effectively reduces the weight of the second connecting rod, and the arc angle can reduce the weight of the second connecting rod while ensuring the working strength of the second connecting rod.

[0026] On the basis of the above solution and as a preferred solution of the above solution: a compression spring is provided on the first connecting rod.

[0027] In the technical solution, when the unfolding and retracting mechanism is performing the unfolding movement of the hatch, the compression spring is placed in a compressed state, thereby generating a compression force and improving the anti-interference capability of the hatch.

[0028] On the basis of the above scheme and as a preferred scheme of the above scheme: the synchronous link mechanism includes a first synchronous link, a second synchronous link and a third synchronous link;

[0029] The second synchronous connecting rod has a first synchronous connecting portion and a second synchronous connecting portion at a certain angle, the end of the first synchronous connecting portion has a first synchronous left clamping plate and a first synchronous right clamping plate arranged on both sides of the mounting seat, the first synchronous rotating rod passes through the first synchronous left clamping plate, the synchronous mounting seat and the first synchronous right clamping plate in sequence, and one end of the first synchronous rotating rod is fixedly connected to the first synchronous left clamping plate, and the other end is fixedly connected to the first synchronous right clamping plate, the synchronous mounting seat is provided with a first synchronous hinge hole for the first synchronous rotating rod to pass through, and the end of the second synchronous connecting portion is hinged to the third synchronous connecting rod;

[0030] One end of the first synchronization connecting rod is fixedly connected to the synchronization crank, and the other end is hinged to the first synchronization connecting part;

[0031] A cabin door synchronization connection seat is provided between the third synchronization link and the cabin door, the cabin door synchronization connection seat is fixed on the cabin door, and the third synchronization link and the cabin door synchronization connection seat are hingedly connected.

[0032] In the present technical solution, a specific structure of a synchronous connecting rod mechanism is disclosed. When the synchronous extension and retraction mechanism opens or closes the cabin door, the synchronous motor drives the synchronous crank to move through the synchronous reducer, and the synchronous crank drives the first synchronous connecting rod to move up or down. The first synchronous connecting rod enables the cabin door to be opened or closed through the second synchronous connecting rod and the third synchronous connecting rod.

[0033] On the basis of the above scheme and as a preferred scheme of the above scheme: a synchronous explosive bolt is provided on the first synchronous connecting rod.

[0034] In the technical solution, the specific installation position of the synchronous explosive bolt is disclosed. When the door of the synchronous extension and retraction mechanism is being moved or retracted, the synchronous explosive bolt explodes, causing the first synchronous screw to break and the synchronous extension and retraction mechanism to stop working.

[0035] On the basis of the above solution and as a preferred solution of the above solution: the synchronous unfolding and retracting mechanism further includes a synchronous shielding component;

[0036] The synchronous shielding assembly further includes a synchronous shielding frame and a synchronous limiting mechanism. The synchronous shielding frame is fixed to the cabin body through a synchronous connecting plate. The top of the synchronous shielding frame is open. The synchronous limiting mechanism is installed on the top of the synchronous shielding frame and is used to limit the movement of the synchronous connecting rod mechanism after the synchronous explosive bolt explodes.

[0037] In the technical solution, the synchronous connecting rod mechanism is separated from the crank after the synchronous explosive bolt explodes, and the separated synchronous connecting rod mechanism enters the synchronous shielding frame through the synchronous limiting mechanism to avoid affecting the deployment or folding of the hatch by the deployment and folding mechanism.

[0038] On the basis of the above scheme and as a preferred scheme of the above scheme: the synchronous limit mechanism includes a first synchronous limiter and a second synchronous limiter with the same structure, and the first synchronous limiter and the second synchronous limiter are respectively installed on the top of the two side plates of the synchronous shielding frame;

[0039] The first synchronous limiter includes a synchronous limit seat, a synchronous limit plate, a synchronous rotating shaft and a synchronous torsion spring installed on the side plate, the synchronous rotating shaft is installed in the synchronous limit seat, one end of the synchronous limit plate is fixedly connected to the synchronous rotating shaft, the synchronous torsion spring is sleeved on the synchronous rotating shaft, the first synchronous pin of the synchronous torsion spring is connected to the synchronous limit plate, and the second synchronous pin of the synchronous torsion spring is fixed in the synchronous limit seat.

[0040] In this technical solution, a specific structure of a synchronous limit mechanism is provided. Under the action of the explosive force of the synchronous explosive bolt, the synchronous link mechanism squeezes the synchronous limit plate into the synchronous shielding frame. Under the action of the synchronous torsion spring, the synchronous limit plate returns to its initial state, limiting the synchronous link mechanism to be located in the synchronous shielding frame.

[0041] On the basis of the above scheme and as a preferred scheme of the above scheme: a synchronous weight-reducing hole is provided on the second synchronous connecting part, and the connection angle between the synchronous weight-reducing hole and the second synchronous connecting part is an arc angle.

[0042] In the technical solution, the synchronous weight-reducing hole on the second synchronous connecting part effectively reduces the weight of the second synchronous connecting rod, and the arc angle can reduce the weight of the second synchronous connecting rod while ensuring the working strength of the second connecting rod.

[0043] On the basis of the above solution and as a preferred solution of the above solution: a synchronous compression spring is provided on the first synchronous connecting rod.

[0044] In the technical solution, when the synchronous extension and retraction mechanism is performing the expansion movement of the hatch, the synchronous compression spring is placed in a compressed state, thereby generating a compression force and improving the anti-interference capability of the hatch.

[0045] On the basis of the above scheme and as a preferred scheme of the above scheme: the power source includes a motor and a reducer, the motor and the reducer are both installed on the cabin, the output shaft of the motor is connected to the reducer, and the output shaft of the reduction motor is connected to the crank;

[0046] The synchronous power source includes a synchronous motor and a synchronous reducer. The synchronous motor and the synchronous reducer are both installed on the cabin. The synchronous output shaft of the synchronous motor is connected to the synchronous reducer. The output shaft of the synchronous reducer is connected to the synchronous crank.

[0047] In the present technical scheme, a specific structure of the power source and the synchronous power source is that the motor drives the crank to move through the deceleration of the reducer, and the reducer reduces the rotation speed of the motor output shaft, thereby increasing the torque of the output rotating shaft; the synchronous motor drives the synchronous crank to move through synchronous deceleration, and the synchronous reducer reduces the rotation of the synchronous output shaft of the synchronous motor, thereby increasing the torque of the output rotating shaft.

[0048] Compared with the prior art, the technical solution proposed by the present invention has the following beneficial effects:

[0049] In the normal state, the unfolding and retracting mechanism and the synchronous unfolding and retracting mechanism work simultaneously and act on the hatch together to perform the unfolding or retracting movement of the hatch. When the unfolding and retracting mechanism is stuck, the control device sends an electrical signal to cause the explosive bolt to explode, and a fracture occurs in the unfolding and retracting mechanism, which no longer participates in the unfolding or retracting of the hatch. At this time, the synchronous unfolding and retracting mechanism continues to unfold or retract the hatch, ensuring that the unfolding or retracting of the hatch can work normally and is not affected. Similarly, when the synchronous unfolding and retracting mechanism is stuck, the unfolding and retracting mechanism continues to unfold or retract the hatch, ensuring that the unfolding or retracting of the hatch can work normally and is not affected.

[0050] The control device sends a command to the motor to rotate and drive the crank to move through the reducer. The crank movement drives the connecting rod mechanism to expand or fold the hatch. When a jamming fault occurs during the process, the control device sends an electrical signal to cause the explosive bolt to explode, disconnect the first connecting rod so that the first connecting rod and the second connecting rod are linked. At the same time, the control device sends a signal to start the synchronous motor. The synchronous motor drives the synchronous crank to move through the synchronous reducer. The crank movement causes the first synchronous connecting rod, the second synchronous connecting rod and the third synchronous connecting rod to rotate, and the hatch continues to expand or fold. When the hatch door is stuck and cannot be separated in an emergency, the design of the present invention ensures that the expansion or folding of the hatch can work normally, thereby improving the stability of the hatch operation.

[0051] During operation, the compression spring or synchronous compression spring can generate a certain compression force when the hatch is fully deployed, so that the hatch has a certain anti-interference ability.

[0052] When problems occur in the deployment and retraction mechanism, the explosive bolt separates the crank and the connecting rod mechanism. Under the action of the explosive force of the explosive bolt, the connecting rod mechanism squeezes the limit plate into the shielding frame. The limit plate returns to its initial state under the action of the torsion spring, limiting the connecting rod mechanism to be located in the shielding frame, avoiding interference with the movement of the synchronous deployment and retraction mechanism, and ensuring normal deployment or retraction of the hatch door.

[0053] When a problem occurs in the synchronous deployment and retraction mechanism, the synchronous explosive bolt separates the synchronous crank from the synchronous connecting rod mechanism. Under the action of the explosive force of the synchronous explosive bolt, the synchronous connecting rod mechanism squeezes the synchronous limit plate into the synchronous shielding frame. Under the action of the synchronous torsion spring, the synchronous limit plate returns to its initial state, limiting the synchronous connecting rod mechanism to be located in the synchronous shielding frame, avoiding interference with the movement of the deployment and retraction mechanism and ensuring normal deployment or retraction of the hatch door.

The hatch has a lower speed at both ends of the unfolding and folding movement, and a faster speed in the middle section. This feature has the following advantages: 1. The output shaft moves at a uniform speed, that is, the motor rotates at a uniform speed, and the control system is relatively simple and reliable; 2. The hatch has a lower speed at both ends of the unfolding and folding movement, which is convenient for the hatch to control the angle accuracy at the unfolding and folding positions; 3. The hatch has a faster speed in the middle section, which can save movement time and improve the emergency response capability of the hatch to unfold and fold.

[0072] See also Figure 6As shown, the present invention is simplified as an example. It should be noted that, in this embodiment, the reducer drives the crank through the drive shaft, AB is the crank, BC is the first connecting rod, CD is the combination of the first connecting part and the mounting seat, DA is the distance from the mounting seat to the crank drive shaft, CE is the second connecting part, EF is the third connecting rod, FG is the distance from the connecting seat to the door shaft, and GD is the distance from the door shaft to the mounting seat, wherein AB, BC, CD and DA constitute a first four-bar linkage, and the length ratio of AB, BC, CD and DA is specifically, AB:BC:CD:DA=80:213:125:203; wherein DE, EF, FG and GD constitute a second four-bar linkage, and the length ratio of DE, EF, FG and GD is specifically, DE:EF:FG:GD=250:130:135:158.

[0073] When the door is in the folded state, the angle between the crank AB and the vertical direction is 22.6°, and the angle between the door FG and the horizontal direction is 35°; the driving mechanism drives the crank to rotate, and the door can be expanded 165°; when the door is expanded to 165°, the door shaft is mechanically limited, and the crank continues to rotate, compressing the compression spring in the first connecting rod 2411, AB and BC are on the same straight line, and the first four-bar linkage is in the dead point position, so that the door has a strong ability to resist interference torque.
