Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of radar antenna locking. More particularly, it relates to a multi-press-point locking mechanism for an antenna array surface. BACKGROUND

[0002] With the development of electronic technology and the needs of modern warfare, the caliber of ground military radar antennas is getting larger and larger. For large-size radar antennas, under the premise of single-vehicle integration, in order to meet the restrictions of transportation limits, the antenna must be divided into blocks, and the overall envelope of the antenna must be compressed through antenna folding action. After the antenna is unfolded to the working state, it must be reliably locked. The existing antenna array surface locking mainly has the following several implementation ways: the first way is to manually connect and lock through screws and auxiliary structural parts. This way not only wastes a lot of time and cannot meet the mobility requirements of modern radars, but also requires high service guarantee. The second way is to lock two array surfaces through electric or hydraulic locking pins. This way is prone to problems such as pin and pin hole being too tight and being stuck, and large gap that cannot meet the precision requirements of the array surface. SUMMARY

[0003] The purpose of the present application is to provide a multi-press-point locking mechanism for an antenna array surface to solve at least one of the above technical problems.

[0004] To achieve the above purpose, the present application adopts the following technical solutions: The present application provides a multi-press-point locking mechanism for an antenna array surface. The antenna array surface includes a main array surface and a side array surface, and the main array surface and the side array surface are hingedly connected. The multi-press-point locking mechanism for the antenna array surface includes a locking component for fixing with the main array surface and a matching part for fixing with the side array surface. The locking component includes an abutting part, a locking part that can rotate horizontally, and a driving part for driving the locking part to rotate. The locking part has a pressing part. The matching part includes a matching part. The matching part includes first and second side wall surfaces arranged in opposite directions. The first side wall surface is used to cooperate with the abutting part, and the second side wall surface is used to cooperate with the pressing part. When the side array surface is unfolded to the main array surface, the first side wall surface abuts against the abutting part, the driving part drives the locking part to rotate, and the pressing part abuts against and presses the second side wall surface, so as to press the matching part between the pressing part and the abutting part, thereby achieving the locking of the main array surface and the side array surface.

[0005] Preferably, the locking component further includes a support fixed to the main array surface. The abutting part is fixed to the support. The locking part is rotatably arranged on the support.

[0006] A preferred embodiment is that the driving component includes a drive motor and a transmission shaft extending horizontally on the main surface; the transmission shaft is rotatably mounted on a support; the transmission shaft is connected to the output end of the drive motor, and the transmission shaft can rotate around its own axis under the drive of the drive motor; the locking component is fixed to the transmission shaft.

[0007] In a preferred embodiment, the axial direction of the output end of the drive motor is the same as the axial direction of the transmission shaft.

[0008] A preferred embodiment is that the output end of the drive motor includes a geared motor, and the transmission shaft is connected to the output end of the geared motor.

[0009] A preferred embodiment is that the locking mechanism includes multiple sets of locking components arranged along the extension direction of the drive shaft; the mating parts and locking parts are matched one-to-one.

[0010] In a preferred embodiment, the mating component includes a fixing part fixed to the edge surface and a connecting part connected to the fixing part; the mating part is fixed to the connecting part.

[0011] A preferred embodiment is that the support is provided with a bushing, and the drive shaft passes through the bushing; the locking member is fixed to the drive shaft by a pin, and the drive shaft is provided with shaft retaining rings located on both sides of the bushing along its own axial direction.

[0012] The present invention also provides an array antenna, including a main array and a side array hinged together and a locking mechanism as described above; the locking component of the locking mechanism is fixed to the main array, and the mating component is fixed to the side array.

[0013] In a preferred embodiment, when the angle between the upper surface of the main array and the upper surface of the side array is 180°, the pressing part of the locking member abuts against the second side wall and applies a locking force to it, so that the first side wall and the abutting member fit and lock together.

[0014] The beneficial effects of this invention are as follows: This invention provides a multi-pressure point locking mechanism for an antenna array. The antenna array includes a main array and side arrays, which are hinged together. The multi-pressure point locking mechanism includes a locking component for fixing to the main array and a mating component for fixing to the side arrays. The locking component includes an abutment, a locking component that can rotate horizontally around an axis, and a driving component for driving the locking component to rotate. The locking component has a pressing portion. The mating component includes a mating portion. The mating portion includes a first side wall and a second side wall that are opposite to each other. The first side wall is used to mate with the abutment, and the second side wall is used to mate with the pressing portion. When the side array is deployed relative to the main array, the first side wall abuts against the abutment, and the driving component drives the locking component to rotate so that its pressing portion abuts against and presses against the second side wall, thereby pressing the mating portion between the pressing portion and the abutment to lock the main array and the side array. The locking mechanism uses the force applied by the locking member to the second side wall of the mating part, combined with the supporting force provided by the abutment member on the first side wall, to form a pair of balanced forces, firmly locking the mating part in the middle. This structure can effectively resist external wind loads or vibration impacts, prevent locking failure, and ensure the stability of the antenna in the working state. Locking and unlocking are completed by automatically driving the locking member to rotate through the drive member, replacing traditional manual operation. This not only improves the efficiency of antenna deployment and folding, but more importantly, avoids the problem of uneven locking force caused by inconsistent force and sequence of manual operation, ensuring a high degree of consistency in the locking state each time. All components of the entire locking mechanism can be installed on the back of the antenna array without occupying additional deployment space, which is conducive to the compact design of the antenna system. At the same time, the abutment member, as a rigid support, combined with the pressing action of the locking member, gives the connection a high local stiffness, further reducing the possibility of deformation under load. This locking mechanism can achieve synchronous locking and unlocking of multiple pressure points, effectively ensuring the connection accuracy and balanced force between the main array and the side array. When subjected to inertial forces or external environmental disturbances, the resulting vibrations and impacts are preferentially transmitted to the drive shaft of the locking mechanism. By achieving mutual cancellation and attenuation of forces within the structure, the direct impact on drive components such as motors and geared motors is reduced, improving the system's immunity and lifespan. Furthermore, the locking force design between the main and side arrays is based on the combined torque generated by inertial forces, wind loads, and sudden stop impacts. The mechanism can dynamically set and maintain the optimal locking force according to actual load requirements by adjusting the motor current, thereby achieving adaptive, adjustable, and reliable locking.

[0025] It should be noted that similar labels and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be discussed further in subsequent figures.

[0026] This invention provides a multi-pressure point locking mechanism for antenna arrays, combined with Figures 1 to 5As shown, the antenna array specifically includes a main array 1 and side arrays 3, which are hinged together by an array rotation hinge point 2. The multi-pressure point locking mechanism of the antenna array includes a locking component for fixing to the main array 1 and a mating component 9 for fixing to the side array 3. The locking component includes an abutment 11, a locking component 8 that can rotate horizontally about an axis, and a driving component for driving the locking component 8 to rotate. The locking component 8 has a pressing part; the mating component 9 includes a mating part 91. The mating part 91 includes a first side wall and a second side wall that are disposed opposite to each other; the first side wall is used to mate with the abutment, and the second side wall is used to mate with the pressing part, that is, the mating part 91 is plate-shaped, with one side of the plate abutting with the abutment 11 and the other side of the plate abutting with the pressing part 81. When the side array 3 is fully deployed relative to the main array 1, the first side wall abuts against the abutment member 11. The driving member drives the locking member 8 to rotate, causing its pressing part 81 to abut against and press against the second side wall, thereby pressing the mating part 91 between the pressing part 81 and the abutment member 11, thus locking the main array 1 and the side array 3 after they are fully deployed. This multi-pressure point locking mechanism achieves stable locking of the main array 1 and the side array 3 by pressing and locking the mating part 91 and the abutment member 11 with the locking member 8. The overall structure is simple and reliable. This mechanism has a simple structure, reasonable layout, reliable limiting, and the layout position and locking force of the locking mechanism can be reasonably designed and controlled according to the antenna length and weight. When the antenna array is deployed, the abutment 11 on the main array 1 contacts the mating part 9 on the side array 3. At this time, the driving component drives the transmission shaft 7 to rotate, thereby driving the locking part 8 to rotate, ultimately pressing the mating part 9 and the abutment 11 together, thus locking the main array 1 and the side array 3. When the antenna is folded, the driving component drives the transmission shaft 7 to rotate in the opposite direction, thereby driving the locking part 8 to rotate in the opposite direction. At this time, the pressing part 81 releases the pressing state on the mating part 9 and the abutment 11, and the side array 3, with the mating part 9, rotates 180° to the left around the array rotation hinge point 2, completing the folding of the antenna array.

[0027] In the above embodiment, the locking assembly further includes a support 6 fixed to the main array surface 1. Both the abutment member 11 and the locking member 8 are fixed to the support 6; the locking member 8 is rotatably mounted on the support 6. The support 6 is screwed to the non-deployed side of the main array surface 1, which is opposite to the deployed side. Figure 1 The support 6 is located on the lower surface of the main array surface 1. This support provides a stable mounting base for the abutment member 11 and the locking member 8, improving the stability of the connection between the locking assembly and the main array surface 1. The abutment member 11 is fixed to the support 6 to ensure accurate abutment positioning and prevent positional shift during abutment. The rotatable locking member 8 enables flexible locking / unlocking of the mating member 9 and the side array surface 3, improving the operational stability and reliability of the locking assembly.

[0028] Regarding the specific structure of the driving component, the driving component includes a drive motor 4 and a transmission shaft 7 extending horizontally on the main array surface 1. The transmission shaft 7 is rotatably mounted on a support 6; the transmission shaft 7 is connected to the output end of the drive motor 4. The transmission shaft 7 can rotate around its own axis under the drive of the drive motor 4; the locking member 8 is fixed to the transmission shaft 7. The drive motor 4 controls the output torque by setting the current value when the array surface is pressed, and through the transmission of the reduction motor and the locking member 8, it ultimately controls the pressing force of the pressing part 81 to meet the requirements of resisting the inertial force, wind load and other impacts during array surface operation. The stable support of the support 6 makes the transmission shaft 7 rotate smoothly and has high operational reliability. The locking member 8 rotates synchronously with the transmission shaft 7, with precise action, and can reliably lock and unlock the array surface. The transmission shaft 7 extends horizontally and is located on the non-deployed side of the main array surface 1, which will not interfere with the deployment of the array surface and is conducive to equipment integration. In the above embodiment, the axial direction of the output end of the drive motor 4 is the same as the axial direction of the transmission shaft 7. This makes the structure more compact and saves installation space. The output end of the drive motor 4 includes a geared motor 14, and the transmission shaft 7 is connected to the output end of the geared motor 14. This invention achieves speed reduction and torque increase through the geared motor 14, enabling the transmission shaft 7 to obtain greater torque, increasing driving force, and enhancing its ability to drive loads; simultaneously, it allows for a more stable output speed of the transmission shaft 7, improving transmission stability and reliability. The output shaft of the geared motor 14 and the transmission shaft 7 are ensured to be coaxially assembled. The drive motor 4 is connected to the input interface of the geared motor 14 via screws, and the output interface of the geared motor 14 is connected to the rotating shaft via a coupling. A reasonable reduction ratio is selected as needed to meet the locking force required for the array locking. Since the array is mainly subjected to a combined torque of inertial force, wind load, and impact force during emergency stops, the output force setting value of the drive motor 4 should be greater than the torque converted to the motor output end by the combined torque.

[0029] After the antenna array is retracted or deployed to its working state, reliable locking is required to limit the vertical displacement of the contact surface and provide a certain preload to counteract the inertial force in the direction of movement and the vibration and impact loads that may be encountered during transportation. Currently, most common locking methods use single-point locking. However, for components with large spans, single-point locking can easily lead to uneven force distribution, and the impact load perpendicular to the contact surface will directly act on the locking cylinder. Over long-term use, this can easily cause cumulative impact damage to the locking cylinder, affecting its reliability and service life. Based on the above, the locking mechanism of this invention includes multiple sets of locking components arranged along the extension direction of the drive shaft 7. The mating parts 9 and locking parts 8 are matched one-to-one. Through the distributed arrangement design of multiple sets of locking components along the extension direction of the drive shaft 7, the locking force is evenly distributed on the contact surface, effectively avoiding the problem of excessive local stress caused by force concentration in the traditional single-point locking method. This structural design disperses the impact load perpendicular to the contact surface to multiple contact points, allowing the load to be transmitted and attenuated through the drive shaft 7, rather than acting directly on a single locking component. This significantly reduces the risk of cumulative impact damage to the locking component during long-term use. It further enhances the structural stability of the locking mechanism under complex operating conditions (such as transportation vibration and wind load disturbance during operation), extends the service life of the locking component and the overall mechanism, and ensures long-term reliable operation of the antenna array after deployment and locking. The multi-pressure point locking mechanism provided by this invention, which offers reliable locking and balanced force distribution, is crucial for improving the stability and safety of the locked object under complex operating conditions and has broad application prospects in fields such as defense industry equipment. This invention achieves locking through an open locking element 8, avoiding jamming, and can provide dynamically set pre-pressure to meet locking force requirements. This multi-pressure point locking mechanism plays a key role in ensuring the stability of the locked object and can be widely used in radar equipment. (Refer to...) Figure 3As shown, taking an example where there are four locking elements 8 and four mating elements 9, both evenly distributed on their respective array surfaces. The number of supports 6 and abutment elements 11 is also four, correspondingly, the array surface rotation hinge points 2 are also set to four. The drive shaft 7 includes two rotating shaft units located on both sides of the reduction motor 14. The output ends on both sides of the reduction motor 14 are connected to the rotating shaft units via couplings to provide driving force for the locking elements 8. Each rotating shaft unit includes two rotating shafts connected by couplings. Each rotating shaft is configured on a different support 6 via a bushing 12, and each rotating shaft is equipped with a locking element 8. The initial installation angle of the four locking elements 8 on the rotating shafts is consistent. During the installation and debugging of the locking elements 8 and the rotating shafts, the thickness of the bearing surface of the support 6 is adjusted to ensure that the locking force of the four locking elements 8 is basically equal in the locked state. Driven by the rotation of the drive motor 4, the geared motor 14 drives the four rotating shafts to rotate synchronously, thereby driving the four locking parts 8 to rotate around the axis of the transmission shaft 7. This causes the pressing part 81 to contact the back of the mating part 9 and press it against the abutment part 11 on the support 6, thus locking the main array 1 and the side array 3. It is understood that in practical applications, the number of locking components and mating parts 9 can be designed according to the antenna length, weight, and accuracy requirements. An even number of supports 6 is preferred, and they are arranged symmetrically on the array surface to ensure that the components of the array surface and locking mechanism are subjected to balanced forces.

[0030] In one specific embodiment, the mating component 9 includes a fixing part 93 fixed to the side array surface 3 and a connecting part 92 connected to the fixing part 93. The mating part 91 is fixed to the connecting part 92. Through the above arrangement, a stable connection between the mating component 9 and the side array surface 3 is achieved. The mating component 9 is fixed to the non-deployed side of the side array surface 3.

[0031] In one specific embodiment, a bushing 12, which is a self-lubricating bushing, is provided on the support 6. The drive shaft 7 passes through the bushing 12; the locking member 8 is fixed to the drive shaft 7 by a pin 10, and the drive shaft 7 is provided with shaft retaining rings 13 located on both sides of the bushing 12 along its own axial direction. The bushing 12 provides support and guidance for the drive shaft 7, enabling the drive shaft 7 to drive the locking member 8 to rotate on the support. The locking member 8 is fixed to the drive shaft 7 by the pin 10, which is a simple and reliable connection structure, facilitating installation and disassembly. The shaft retaining rings 13 are located on both sides of the bushing 12 along its axial direction, which can effectively ensure the relative position stability between the bushing 12 and the drive shaft 7, improving the stability of the overall structure. The outer circle of the bushing 12 is fitted with the shaft hole on the support 6 and is fastened axially by screws. After passing through the shaft hole of the support 6, the bushing 12 protrudes 1mm from the inner side of the support 6, so that the locking member 8 only contacts the side of the bushing 12, while maintaining a gap with the support 6. After the shaft is installed in conjunction with the self-lubricating bushing, it is constrained axially by the shaft retaining ring 13.

[0032] The present invention also provides an array antenna, including a main array 1 and a side array 3 hingedly connected, and a locking mechanism as described above. The locking component of the locking mechanism is fixed to the main array 1, and the mating part 9 is fixed to the side array 3. Further, when the angle between the upper surface of the main array 1 and the upper surface of the side array 3 is 180°, the pressing part 81 of the locking part 8 abuts against the second side wall and applies a locking force to it, causing the first side wall to fit tightly against the abutting part 11. The upper surface of the main array 1 and the upper surface of the side array 3 are unfolded surfaces; here, the upper surface refers to... Figure 1 As shown, the top surfaces of the main array 1 and the side array 3 are in the deployed state. The angle between the upper surface of the main array 1 and the upper surface of the side array 3 ranges from 0° to 180°. When the angle between the upper surfaces (deployed surfaces) of the two arrays is 180°, the antenna is in the deployed state (working state), and when the angle is 0°, the antenna is in the folded and stored state.

[0033] More specifically, the locking process of the locking mechanism of the present invention is as follows: the main array 1 and the side array 3 are folded and stored, the main array 1 remains stationary, and the side array 3 rotates 180° around the array surface hinge point under the action of the driving force so that the angle between the upper surface of the main array 1 and the upper surface of the side array 3 is 180°. The mating part 91 can be a locking block, and the locking element 8 can be a pressure hook. At this time, the locking block is in contact with the side plate of the abutment 11 on the support 6. The drive motor 4 rotates to drive the reduction motor 14. The output shaft of the reduction motor 14 drives the transmission shaft 7 to rotate, thereby driving the pressing part 81 at the tail of the pressure hook to rotate toward the locking block. Finally, the pressing part 81 contacts the locking block and continues to move. When the output current of the drive motor 4 reaches the set value, the movement stops. At this time, the pressure hook provides a large locking force, so that the locking block is tightly pressed against the abutment 11 on the support 6. The locking process ends, and the antenna is in the unfolded working state. The unlocking process is as follows: At the start of the unlocking process, the drive motor 4 rotates in the opposite direction to the locking process, driving the reduction motor 14 and causing the transmission shaft 7 to rotate in the opposite direction, thereby driving the tail of the pressure hook to rotate away from the locking block, and finally stopping at the preset position. Then, under the action of external driving force, the side array 3 rotates around the array surface hinge point 2 from 180° to 0° with the main array surface, and the unlocking process ends, and the antenna is in a folded storage state.

[0034] In summary, the present invention provides a multi-pressure point locking mechanism for an antenna array. The antenna array includes a main array and side arrays, which are hinged together. The multi-pressure point locking mechanism includes a locking component for fixing to the main array and a mating component for fixing to the side array. The locking component includes an abutment, a locking component that can rotate horizontally around an axis, and a driving component for driving the locking component to rotate. The locking component has a pressing portion. The mating component includes a mating portion. The mating portion includes a first side wall and a second side wall that are opposite to each other. The first side wall is used to mate with the abutment, and the second side wall is used to mate with the pressing portion. When the side array is deployed relative to the main array, the first side wall abuts against the abutment, and the driving component drives the locking component to rotate so that its pressing portion abuts against and presses against the second side wall, thereby pressing the mating portion between the pressing portion and the abutment to lock the main array and the side array. The locking mechanism uses the force applied by the locking member to the second side wall of the mating part, combined with the supporting force provided by the abutment member on the first side wall, to form a pair of balanced forces, firmly locking the mating part in the middle. This structure can effectively resist external wind loads or vibration impacts, prevent locking failure, and ensure the stability of the antenna in the working state. Locking and unlocking are completed by automatically driving the locking member to rotate through the drive member, replacing traditional manual operation. This not only improves the efficiency of antenna deployment and folding, but more importantly, avoids the problem of uneven locking force caused by inconsistent force and sequence of manual operation, ensuring a high degree of consistency in the locking state each time. All components of the entire locking mechanism can be installed on the back of the antenna array without occupying additional deployment space, which is conducive to the compact design of the antenna system. At the same time, the abutment member, as a rigid support, combined with the pressing action of the locking member, gives the connection a high local stiffness, further reducing the possibility of deformation under load. This locking mechanism can achieve synchronous locking and unlocking of multiple pressure points, effectively ensuring the connection accuracy and balanced force between the main array and the side array. When subjected to inertial forces or external environmental disturbances, the resulting vibrations and impacts are preferentially transmitted to the drive shaft of the locking mechanism. By achieving mutual cancellation and attenuation of forces within the structure, the direct impact on drive components such as motors and geared motors is reduced, improving the system's immunity and lifespan. Furthermore, the locking force design between the main and side arrays is based on the combined torque generated by inertial forces, wind loads, and sudden stop impacts. The mechanism can dynamically set and maintain the optimal locking force according to actual load requirements by adjusting the motor current, thereby achieving adaptive, adjustable, and reliable locking.

[0035] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. For those skilled in the art, other variations or modifications can be made based on the above description. It is impossible to exhaustively list all the implementation methods here. All obvious variations or modifications derived from the technical solutions of the present invention are still within the protection scope of the present invention.
