Description

The invention relates to the design of vehicles for land, water and air transport and can be used in the design of nodes for fixing in the closed position of the rotary shutters, opened and closed in the process of movement.

In particular, in aircraft construction, the device can be used in the construction of cargo compartment doors, landing gear fairings, bomb release flaps, various hatches, etc.

When the vehicle is moving, spontaneous opening of the closed rotary doors must be excluded, in addition, in order to eliminate friction losses caused by contact with the external environment, the closed leaf must be associated with other surfaces of the vehicle due to tight contact along the bypass of the closed cavity.

A lock for connecting and disconnecting a streamlined aircraft sash is known, in which the rotary sash is fixed by a locking device due to the entry of the fixed elements into the grooves of the rotary hook element, the closed and open position of the hook element is fixed by springs that create a moment of force relative to its axis of rotation patent CN 108100237 B, IPC V64S 25/16, V64S 25/20, V64S 25/26; publ. 01/05/2021.

In the considered design, the locking device can be released due to the opening of the leaf under the influence of undesirable external influences or due to the weakening of the force on the springs.

A device for closing and sequentially opening a vehicle lid is known, comprising a drive and several locks made in the form of an eccentric shaft with a hook-grip located along the periphery of the lid and the corresponding clutch elements provided with fingers located on the bypass of the contour to be closed, while the eccentric shafts are interconnected and driven by cardan gears (patent RU No. 2457161 C1; IPC B64G 1/64, B6 B 19/14, B64C 1/14; publ. 27.07.2012).

When closing under the action of the drive, the cardan gears turn the eccentric shafts, and the hooks interact with the corresponding clutch elements.

The disadvantage of the design lies in the dependence of its performance on the integrity of the cardan gears, since in the event of jamming or premature closing of at least one grip, the operation of the device stops.

Known locking mechanism cargo doors of the aircraft or doors in the fuselage compartment, containing a sliding element, the elements of the fuselage compartment, made in the form of hooks, and rigidly mounted on the contour of the opening in the fuselage and elements mounted on the door, made in the form of fork elements with two arms connected using a horizontal rib (patent JP 5133425 B2; IPC: B64C 1/14, E05B 65/12; publ. 01/30/2013). When the door is closed, the fork elements move into the zone of engagement with the elements of the fuselage compartment, while the door is locked using a sliding element.

The considered design is difficult to implement, since it contains many mutually positioned elements, in addition, during operation, it is possible to select material in the contact zones, which will lead to a loose fit of the door leaf along the contour of the closed cavity.

The prototype of the invention is a system for fixing a pivot door and a door having such a system (patent U S10526064 B2; IPC: B64C 1/14; E05C 19/12, E05C 3/12; publ. 01/07/2020).

The locking system is equipped with a power latch, rotatable and locking shafts, as well as at least several locking devices containing a rotary engaging element and a fixed element, while the profile of the groove in the engaging element is made with the possibility of engaging the fixed element when sash closing.

In this case, the rotary fixed elements are connected to the drive shaft by a mechanical transmission element, and the fixing shaft is provided with a unit for locking the mechanical transmission element.

The shafts are driven by a power drive, which is activated in case of closing or opening of the swing door.

The disadvantages of the prototype are the impossibility of pressing the rotary sash along any structurally defined points of the perimeter of the bypass of the opening to be closed, the non-synchronization of the closing of the fixation device with the closing of the rotary sash and the lack of a constant force of pressing the rotary sash to the vehicle body at the installation site of the locking devices, which does not compensate for the permissible deformation of the sash and bypassing the hull at the place of the opening in the process of movement. Another disadvantage is the location of the drive and actuating (moving) elements on the cover, which requires flexible or rotary elements in the power supply system of the drive.

The invention was created while solving the technical problem of developing the design of the device for fixing the rotary sash, which implements the possibility of pressing the rotary sash at any structurally defined points of the perimeter of the bypass of the opening to be closed, the synchronism of the closing of the fixing device with the closing of the rotary sash, ensuring a constant force of pressing the rotary sash to the transport body means at the place of installation of the locking devices, compensating for the permissible deformations of the sash and the bypass of the body at the place of the opening during movement.

The technical result achieved in the implementation of the invention is the expansion of the arsenal of technical means, as well as the provision of multi-point pressing of the closed sash to the bypass of the cavity in the vehicle at any selected perimeter points in accordance with the design development, the implementation of the closing of each of the locking devices synchronously with each other and with turning the sash to close, excluding premature closure of one of them, due to the occurrence of a moment that prevents its closure, and the implementation of a constantly acting force of pressing the sash to the vehicle body in the area of installation of the locking devices, resulting in guaranteed closing of each of the locking devices and constant pairing the surface of the sash with the surface of the vehicle along the bypass of the opening, which ensures streamlining and tightness when the sash is closed, in addition, the synchronous pressing of the sash to the bypass of the closed niche at the point of contact, as well as Implementation of additional support nodes in the area close to the attachment points on the leaf of the leaf drive mechanism units for direct transfer of the forces of these units to the power set of the vehicle body, compensating for the mismatch in the actuation of the leaf drive mechanisms

The device for fixing the rotary shutter in the vehicle Fig. 1, 2, is used during the operation of the rotary sash 1, designed to close the opening in the vehicle along its bypass 32. When the vehicle is in operation, the sash is in the closed position, if necessary, the sash rotates to open, and then returns to the closed position. When the sash is open, the device is waiting for the next closing of the swing sash. The sash can be installed on hinged hinges 33, the sash is rotated relative to the axis of rotation 13, the sash rotation drive 34 can be implemented, for example, by pneumatic cylinders, hydraulic cylinders, etc. on sash 1.

The required number of locking devices 5 and side locking devices 8, as well as their installation locations, are determined by design study in order to determine the number of necessary pressure points] for mating the surface of the closed sash with the vehicle body along the contour of the opening to be closed, which, together with other features of the invention, provides multipoint pressing the closed sash against the bypass of the cavity in the vehicle along any selected points of the perimeter.

The locking device 5 contains a rotary engagement element 6 rigidly mounted on the rotary shaft 3 and a fixed element 7.

The side locking device 8 comprises a swivel grip 9 rotatably mounted on an axle 14 fixed on the vehicle body 12 and an additional fixed element 11 mounted on the swivel sash 1 with the possibility of engaging it with the swivel grip 9.

Compression springs can be springs made according to OST 1 11208-73, Compression springs. Design and dimensions. Preliminary compression of the springs is necessary to create a constant force that creates a moment of force acting on the engaging element, and is calculated taking into account the provision of the necessary value of the created moment for the functioning of the operation of the turning sash fixation device, after which it is verified experimentally.

To increase the rigidity of the structure when the sash is closed, as well as for the convenience of servicing the supply lines to the rotation drive 2 of the drive shaft, the rotary 3 and drive 4 shafts can be mounted on the body 12 of the vehicle, for example, placed on bearings in brackets rigidly connected to the power elements housing, while the fixed elements 7 and the additional fixed element 11 are installed on the inside of the rotary sash 1.

To optimize the design of the axis of the rotary 3 and drive 4 shafts can be parallel to the axis 13 of rotation of the sash.

It is preferable that the rotary 3 and drive 4 shafts are placed directly at the bypass of the opening in the housing.

To optimize the design, the axis 14 of the rotary gripper can be parallel to the axis of the rotary shaft 3.

In order to be able to adjust the position of the rotary engagement elements 6 can be installed on the rotary shaft 3 using a detachable connection, for example, using a bolt clamp or splines, gear connection.

To be able to install a side locking device in places remote from the bypass of the closing opening, or to adapt the fixing device to the installation of equipment inside the vehicle, the axis 14 of the swivel grip can be mounted console to the vehicle body 12.

The crank 22 is rigidly mounted on the drive shaft 4 and is connected to the rotation drive 2 of the drive shaft.

The drive for turning the rotary shaft can be made pneumatic, hydraulic or electric and equipped with a rectilinearly moving actuating element in the form of a rod 23, for example, in the form of a hydraulic cylinder according to GOST 16514-96 Volumetric hydraulic drives. Hydraulic cylinders. General technical requirements.

In particular cases, the crank can be made in the form of a multi-link rocking chair, equipped with a pin 24, the connection with the drive for turning the drive shaft is provided by installing the pin in the slot 25, made in the rectilinearly moving actuating element of the drive - the rod 23.

The swivel grip 9 is equipped with a rocker 10 ₁ connected through a drive rod 21 with a swivel drive rocker 20 mounted on the swivel shaft 3.

In the description of the invention, rocking chairs mean swivel arms that are rigidly fixed relative to the axes of rotation.

To ensure the operation of the device, the rotary engaging elements 6 can be made in the form of a hook or fork with a groove 15, and the rotary grip 9 - in the form of a hook.

According to the technical concept, during the design engineering, when the vehicle sash is closed, the fixed element 7 is engaged with the profile of the groove 15 of the engaging element 6 and the rotary grip 9 of the additional fixed element 11, respectively.

The profile of the groove 15 in the engaging elements 6 and the geometric design of the rotary grip 9 is determined by the graphic design method, taking into account the possibility of engaging with the fixed element 7 and the additional fixed element 11 when the sash is closed, respectively.

The fixed elements 7 and the additional fixed element 11 can be made in the form of an eyelet or a bracket.

Compression springs 16, at one end 28 are connected to the body 12 of the vehicle, and the other 29 - with the engaging element 6.

To reduce friction and ensure that the load is directed along the axis of the springs without distortion, the springs 16 can be connected with their ends 28, 29 to the body 12 of the vehicle and, or the engaging elements 6 using bearings, for example, made in accordance with GOST 3635-78, Swivel bearings. Specifications. Bearings can be pressed into sockets and equipped with connecting brackets for fixing the ends of the springs.

прижимая зацепляющий элемент 6 к фиксируемому элементу 7.The fixing points are determined during the design development in such a way that when the device is closed, for example, by determining the position of the axes of the springs 30 relative to the axis of the rotary shaft 3, a moment of force is created to close

pressing the hooking element 6 to the fixed element 7.

The direction of the pressing moment of force is structurally ensured by the appropriate location of the axis of the spring 30 relative to the axis of the rotary shaft 3 in the position when the sash is closed.

During the design study, the place of installation of the ends of the springs 28, 29 and the magnitude of the preloading forces are determined in accordance with the course "Theoretical mechanics", for example, Arkusha A.I., Theoretical mechanics and strength of materials. - M.: Higher school, 1998, and are confirmed experimentally.

The drive 2 of the drive shaft blocks the rotation of the crank 22 in the direction corresponding to its rotation to open 26 when the leaf is closed, and corresponding to its rotation to close 27 when the device is in standby mode (Fig. 6, 7).

Also, the drive 2 of the drive shaft can perform a forced rotation of the crank in the event of opening the door of the vehicle.

The blocking can be implemented by withdrawing the drive rod 23 and fixing it in a position in which the crank pin 24 rests against the surface limiting the slot 25 in the rod, which prevents it from turning in the corresponding direction (Fig. 9, 16). The blocking of the crank 22 prevents the rotation of the drive shaft 4 and the rotary shaft 3 connected to it through the rockers and the thrust, as well as the rotary engagement elements 6 installed on the rotary shaft, as well as the rocker of the drive for turning the grip 20, preventing spontaneous opening of the locking devices 5 and the side locking device 8 or ensuring their fixation in the standby mode for the next closing of the swing sash.

The process of operation of the device for fixing the rotary sash in the vehicle (hereinafter referred to as the device) during its implementation (Fig. 5) may contain the sequence of the following modes:

- waiting mode for the next closing, in which the drive of the drive shaft blocks the movement of the elements of the device in the direction of closing, structurally, in the case of closing the leaf, it is possible to engage the fixed elements with the profile of the grooves of the engaging elements and create a connection of the rotary grip with an additional fixed element;

- the mode of the beginning of the transfer to the closed position, in which the fixed element is brought into contact with the contour of the groove in the engaging element, the signal about the beginning of closing is transmitted to the drive for turning the drive shaft and the movement of the device elements in the direction of closing is unlocked;

- the mode of moving to the closed position, in which the elements of the device are moved in the direction of closing and a connection of the rotary grip with an additional fixed element is created

- mode of locking the sash in the closed position, in which, according to a given position of the crank, the rotation drive of the rotary shaft blocks the movement of the device elements in the direction of opening and creates a moment of force on the rotary shaft in the direction of closing;

- the mode of opening and switching to the standby mode, in which the signal of the beginning of opening is transmitted to the drive of rotation of the drive shaft, the movement of the elements of the device in the opening direction is unlocked, the elements of the device are moved in the direction of opening by the drive of rotation of the drive shaft, while the rotary hook elements are removed from engagement with the fixed elements, and the rotary grip - from the connection with the additional fixed element, according to the given position of the crank, the rotation drive of the rotary shaft blocks the movement of the device elements in the direction of closing, putting the device into standby mode.

The kinematic diagram of the movement of the device elements when opening the sash and putting the device into standby mode, revealing the directions of their movement to open and put the device into the standby position, is shown in Fig. 6.

The kinematic diagram of the movement of the elements of the device when the sash is closed, revealing the directions of their movement when closing, is shown in Fig. 7.

In the absence of contact between the contours of the grooves 15 of the engaging elements 6 with the fixed elements 7, when the rotary sash is in the open position, the device is in the waiting mode for the next closing (Fig. 8 (the sash rotation drive is not shown).

The drive (2) of the drive shaft blocks the rotation of the crank 22 in the direction of rotation to close (Fig. 9), for example, fixing the contact of the pin 24 of the crank with the contour of the groove 25 in the actuating element, excluding the rotation of the crank in the direction of closing.

In accordance with the design, the blocking of the crank causes blocking of the drive shaft 4, with a rocker rigidly mounted on it, and, consequently, blocking: movement of the rod, rotation of the rocker rigidly mounted on the rotary shaft, and the rotary shaft 3, as well as rigidly mounted on the rotary shaft swivel engagement devices 6 and rocking drive rotation of the capture 20, the blocking of which will block the movement of the drive rod of the swivel grip 21, and connected to it by the rocker, swivel grip 9; as a result, the movement of the elements of the device in the direction of closing is blocked, and spontaneous change in the position of the hook elements and the rotary grip is prevented. (Fig. 10).

According to the design concept, when the sash is closed, the geometric dimensions and the execution of the device elements provide the possibility of engaging the movable fixed elements with the profile of the grooves of the engaging elements (Fig. 12), as well as creating a connection of the rotary grip with an additional fixed element.

возникший от силы предварительного нагружения каждой из пружин

действующий по оси 30 пружины на плече 31, равном расстоянию от оси пружины 16 до оси поворотного вала 3.In a particular case of execution, in order to reduce loads in the device and dampen external loads, the compression springs create a moment of force, holding the rotary engaging element in the standby mode (Fig. 11), while creating a total moment reduced to the rotary shaft to hold the engaging elements in the holding mode.

arising from the preload force of each of the springs

acting along the axis 30 of the spring on the shoulder 31, equal to the distance from the axis of the spring 16 to the axis of the rotary shaft 3.

In the following disclosure, the scheme for determining the moments created by the compression springs on the rotary engagement elements relative to the axis of the rotary shaft is similar.

To fix the position of the rotary engagement elements and the rotary grip in standby mode, the rotary shaft 3 can be provided with stops in the vehicle body.

, поворачивающий створку 1, при этом, фиксируемые элементы 7 входят в пазы 15 поворотных зацепляющих элементов 6, и в результата контакта с поверхностью контура паза 15 создают момент, стремящийся повернуть зацепной элемента в положение на закрытие

If it is necessary to close the opening in the vehicle with a rotary sash, it is rotated in the direction of closing, while the sash rotation drive 34 creates a moment to close the sash

, turning the leaf 1, while the fixed elements 7 enter the grooves 15 of the rotary hooking elements 6, and as a result of contact with the surface of the groove contour 15, a moment is created that tends to turn the hook element into the closing position

The device operates in the mode of the beginning of the transfer to the closed position.

The rotation drive of the drive shaft 2 receives a signal about the beginning of the flap to the closed position, for example, by feedback from the drive to rotate the flap 34, and when it is detected that the closing moment has been created, it unlocks the crank 22, without preventing its further movement in the closing direction in accordance with the kinematic closing scheme.

под действием приведенного к оси поворотного вала суммарного момента силы на его поворот в направлении на закрытие

элементы устройства перемещаются в направление на закрытие, при этом жестко установленная на поворотном валу качалка привода поворота захвата 20 перемещает приводную тягу поворота захвата 21, которая посредством качалки 10 поворачивает поворотный захват 9 для создания соединения с дополнительным фиксируемым элементом 11.In the mode of moving to the closed position, under the action of the load created by the moving fixed element on the surface along the contour of the groove of the hook element at the point of contact in the locking devices 5, a moment of rotation to close is created

under the action of the total moment of force reduced to the axis of the rotary shaft to turn it in the direction of closing

the elements of the device move in the direction of closing, while the rocker of the grip rotation drive 20, rigidly mounted on the rotary shaft, moves the drive rod of the grip rotation 21, which, by means of the rocker 10, rotates the rotary grip 9 to create a connection with an additional fixed element 11.

инициирован моментом на закрытие створки

от привода поворота створки, реализуется закрытие каждого из замковых устройств синхронно друг с другом и с поворотом створки на закрытие, исключающее преждевременное закрытие одного из них, ввиду возникновения момента, препятствующего его закрытию, в результате чего обеспечивается одновременность закрытия замковых устройств в соответствии с кинематической схемой, при этом синхронное прижатие створки к обводу закрываемой ниши по месту контакта, а также выполнение дополнительных опорных узлов в зоне, приближенной к точкам крепления на створке агрегатов механизма привода створки для непосредственной передачи усилий этих агрегатов на силовой набор корпуса транспортного средства, компенсирующее рассогласование срабатывания механизмов привода створки и закрытие (открытие) замковых устройств исключает необходимость дополнительного увеличения выше расчетного усилия на приводе поворота створки и приводе приводного вала - необходимость предусмотренного конструктивного «перетяга».Since when the device is moved to the closed position (Fig. 10, 11, 12)

triggered by the moment to close the leaf

from the sash rotation drive, each of the locking devices is closed synchronously with each other and with the sash turning to close, excluding premature closing of one of them, due to the occurrence of a moment that prevents it from closing, as a result of which the simultaneous closing of the locking devices is ensured in accordance with the kinematic scheme , while the synchronous pressing of the sash to the bypass of the closed niche at the place of contact, as well as the implementation of additional support nodes in the area close to the attachment points on the sash of the units of the sash drive mechanism for direct transfer of the forces of these units to the power set of the vehicle body, compensating for the mismatch of the operation of the mechanisms sash drive and closing (opening) of the locking devices eliminates the need for an additional increase above the calculated force on the sash rotation drive and the drive shaft drive - the need for the provided structural "tightening".

(Фиг. 12), при расчете усилия, создающего поворот устройства на перемещение в положение на открытие,

должен большим, чем

то есть:

In a particular case of execution, when creating compression springs, a moment of force holding the rotary engagement element in standby mode

(Fig. 12), when calculating the force that creates the rotation of the device to move to the opening position,

owe more than

that is:

направленного на удержание поворотного вала 3 в положении ожидания, производится поворот элементов устройства до положения, при котором оси пружин 30 будут пересекаться с осью поворотного вала 3 (Фиг. 13).After overcoming the total moment of the springs

aimed at holding the rotary shaft 3 in the waiting position, the elements of the device are rotated to a position in which the axes of the springs 30 will intersect with the axis of the rotary shaft 3 (Fig. 13).

For the purposes of further description, this relative position of the elements is referred to as the “position of dynamic fracture”.

In the position of dynamic fracture, the spring 16 does not create a moment of force on the rotary engagement element 6, which is reduced to the rotary shaft 3, i.e.

направленный на поворот зацепляющих элементов на закрытие, прижимая поверхность по контуру паза в месте контакта зацепляющего элемента к фиксируемому элементу.After passing the dynamic fracture position, the compression springs generate a closing torque

aimed at turning the hooking elements to close, pressing the surface along the contour of the groove at the point of contact of the hooking element with the fixed element.

суммированного с.

After passing through a dynamic fracture, the elements of the device move in the direction of closing under the action of

summarized with.

As the inner surface of the sash 1 comes into contact with the surface of the vehicle body 12 along the contour of the opening in the body, the action of the drive for turning the sash stops and the device operates in the mode of fixing the sash in the closed position (Fig. 15 (the drive for turning the sash is not shown).

The operation of the sash rotation drive can be stopped by a signal from the sash closing sensor installed on the vehicle body.

The rotation drive of the drive shaft 2 receives a signal to stop the operation of the drive to rotate the sash, for example, by feedback, and moves the crank 22 to a position corresponding to the end of the movement of the device elements in the closing direction. When moving, the drive rotates the drive shaft 4 and further moves the elements of the device in accordance with the kinematic diagram.

After moving the crank 22 to a position, structurally defined as the position corresponding to the closing of the locking devices and the side locking device, the drive of rotation of the drive shaft blocks the movement of the crank in the opening direction (Fig. 16).

In accordance with the design, the blocking of the crank 22 causes blocking of the drive shaft 4 with the rocker 18 rigidly mounted on it and, consequently, blocking: movement of the rod 19, rotation of the rocker 17, rigidly mounted on the rotary shaft 3, and the rotary shaft, as well as rigidly mounted on the rotary shaft of the rotary engagement devices 6 and the rocker of the drive for turning the grip 20, the blocking of which will block the movement of the drive rod 21 for turning the grip and the rotary grip 9 connected to it by the rocker 10; as a result, the movement of the elements of the device in the direction of opening is blocked and the change in the position of the hook elements and the rotary grip is prevented, excluding spontaneous opening of the lock 5 and side lock 8 devices.

производится поворот поворотного вала с зацепляющими элементами в направлении на закрытие и достигается постоянное прижатие поворотной створки к корпусу транспортного средства в месте установки замковых устройств (Фиг. 17, 18).Since when the device is closed, fixing the rotary sash in the closed position, the rotary engaging elements are loaded with compression springs that create closing forces, pressing the engaging element against the fixed element, a constantly acting force of pressing the sash to the vehicle body is realized in the area of installation of the locking devices. For example, in the case of structural deformation and a change in the position of the fixed element under the action of

the rotary shaft with the engaging elements is rotated in the direction of closing, and the rotary sash is constantly pressed against the vehicle body at the installation site of the locking devices (Fig. 17, 18).

The rotary shaft 3 can be made torsion, for example, made of structural spring-spring steel 50HFA, to compensate for misalignment when installing rotary engagement elements 6, as well as to compensate for the own deformations of the vehicle body from external loads and to maintain the operability of the locking mechanism in case of an unforeseen change the position of the fixed elements 7 in the case of permissible deformations of the vehicle body and the rotary sash during movement, to compensate for the mating of the surface of the rotary sash with the surface of the vehicle body.

поворачивающий створку 1, при этом фиксируемые элементы 7 в результате контакта с поверхностью контура паза 15 создают момент

стремящийся повернуть зацепной элемент в положение на открытие.If it is necessary to open the opening in the vehicle, the sash is rotated in the direction of opening. The sash rotation drive 34 generates the moment to open the sash

turning the sash 1, while the fixed elements 7, as a result of contact with the surface of the groove contour 15, create a moment

seeking to rotate the toe element to the opening position.

The device operates in the opening mode and transfer to the standby mode (Fig. 19).

The drive for turning the drive shaft 2 receives a signal about the beginning of the movement of the sash to the open position, for example, by feedback from the drive for turning the sash, unlocks the crank 22 and moves it to a position corresponding to the end of the movement of the device elements in the opening direction. When moving the crank, the drive shaft 4 is rotated and the elements of the device are further moved in accordance with the kinematic diagram.

After the crank 22 has been moved to a position determined by design to wait for the next close, the drive shaft rotation actuator blocks the movement of the crank in the closing direction.

Changes and modifications to the disclosed embodiment may be apparent to those skilled in the art and are within the claimed scope of the patent claims within the scope of the claims, subject to technical equivalents.

To ensure the possibility of unlocking the sash without using the sash rotation drive during maintenance, provision should be made for disabling the drive for turning the drive shaft, as a result of which the crank rotation is unlocked in the direction of opening and it is possible to open the locking devices when the sash is forcefully opened.
