Description

Technical Field

[0001] The invention relates to radar antenna technology, and in particular to a radar antenna locking device. Background Art

[0002] The radar antenna device is a device used to radiate and receive electromagnetic waves and determine the direction of its detection. The radar antenna has the function of focusing electromagnetic waves into beams, and emitting and receiving electromagnetic waves in a directionally direction. Under modern high-tech conditions, high mobility is an important tactical indicator of vehicle-mounted radar antennas, and whether the radar antenna can be reliably erected and withdrawn in the shortest time is an important means to improve the above mobility. In order to facilitate the conversion of the erection and withdrawal states of the radar antenna, bolt fixing or locking pin structure is usually used to achieve the purpose of fast and reliable locking of the radar mechanism components that have moved into place. Among them, the bolt fixing structure is to use bolts to directly tighten the structural connection points after the antenna is flipped to the specified position. A more advanced locking pin form is to replace the power of the locking pin with a motor or hydraulic cylinder drive.

[0003] A Chinese invention patent with announcement number CN105489999B discloses an integrated follow-up locking and automatic unlocking device. The integrated follow-up locking and automatic unlocking device uses a unique linkage hook lock structure to achieve fast and reliable locking and unlocking actions after the relevant mechanisms on the radar antenna are in place, thereby efficiently completing the conversion operation requirements of the radar antenna in multiple states. Compared with the traditional fixing methods of bolts or locking pins, such as unstable and unreliable positioning, cumbersome disassembly and assembly, and low efficiency, the present invention is based on achieving high working reliability and high operating efficiency of the radar antenna in various states, and fully utilizes the elastic recovery function of the torsion spring hinge structure and the automatic power control effect of the power unit; by cleverly coordinating the downward force of the locking rod, a series of rapid linkage response functions are achieved, including locking rod pressing down - hook body being stressed - torsion spring being compressed - hook handle swinging to the specified position - power unit driving the rocker to clamp the hook handle. However, this locking device has high requirements on the position accuracy of the locking rod, and has low environmental adaptability and reliability. At the same time, it lacks locking measures for the radar antenna when the user has to deploy the radar antenna while the vehicle is driving due to mission requirements. Summary of the invention

[0004] The object of the present invention is to provide a radar antenna locking device to solve the above-mentioned deficiencies in the prior art.

[0005] In order to achieve the above object, the present invention provides the following technical solution: a radar antenna locking device, comprising:

[0006] A support assembly mounted on the top of the vehicle body;

[0007] The locking assembly is installed on one side of the radar antenna on the top of the vehicle body, and can be connected to the supporting assembly to lock and limit the radar antenna.

[0008] Furthermore, the support assembly is a support rod vertically fixedly installed on the top of the vehicle body perpendicular to the top of the vehicle body, and the locking assembly is a locking block fixedly installed on one side of the radar antenna. A slot that can be plugged into the top of the support assembly is opened on one side of the locking block, so that when the radar antenna is in a folded state, the support rod can be inserted into the slot, and the radar antenna in the folded state is locked and limited by the plug-in connection between the support rod and the locking block.

[0009] Further, the locking assembly is an L-shaped frame fixedly mounted on one side of the radar antenna, and the supporting assembly includes a locking auxiliary mechanism;

[0010] The locking auxiliary mechanism includes:

[0011] two support sleeves;

[0014] Furthermore, the locking auxiliary mechanism also includes:

[0015] Two fixing pins, which are respectively fixedly installed inside the two supporting sleeves and are respectively slidably connected to the inner walls of the two inclined grooves;

[0016] Two connecting members are rotatably mounted on ends of two supporting sleeves that are away from each other.

[0017] Furthermore, the locking auxiliary mechanism also includes:

[0018] An eccentric block is fixedly mounted on the outside of the rotating shaft and located between the two supporting sleeves, and the eccentric block also abuts against one side of the locking assembly;

[0019] The rotating shaft drives the eccentric block to rotate, and the eccentric block can apply a pressure along the width direction of the radar antenna to the locking assembly;

[0020] Two locking sleeves are respectively fixedly mounted on the ends of the two connecting members 1 that are away from each other. Further, the support assembly also includes a diagonal support mechanism 1, which includes two hydraulic rod assemblies that are symmetrically and obliquely distributed, and the top ends of the two hydraulic rod assemblies are both hinged with a hinge seat 1.

[0021] Furthermore, a turntable 1 rotatably connected to one side of the radar antenna is fixedly mounted on one side of the two articulated seats 1, and the outer sides of the two hydraulic rod assemblies near the top ends are rotatably connected to the inner sides of the two locking sleeves respectively;

[0022] The bottom ends of the two hydraulic rod assemblies are both hinged with an articulated seat 2, and one side of the two articulated seats 2 is fixedly installed with a turntable 2 which is rotatably connected to the top of the vehicle body.

[0023] Furthermore, the support assembly also includes a second diagonal support mechanism and an auxiliary fixing mechanism;

[0024] The second diagonal bracing mechanism comprises two threaded rods which are symmetrically inclined, the outer sides of the threaded rods are threadedly connected with threaded sleeves, the threaded sleeves are located above the threaded rods, the bottom ends of the threaded rods are fixedly mounted with universal joint end 1, and the bottom of the universal joint end 1 is connected with universal joint end 2 via a cross shaft;

[0025] The outer sides of the two threaded sleeves close to the top ends are rotatably connected to the inner sides of the two locking sleeves respectively;

[0026] The top ends of the two threaded sleeves are both hinged with hinged seats 4, and one side of the two hinged seats 4 is fixedly mounted with a turntable 3 which is rotatably connected to one side of the radar antenna.

[0027] Furthermore, a toothed disc rotatably connected to the top of the vehicle body is fixedly mounted at the bottom of the universal joint end 2, a driving member 1 is also fixedly mounted on the top of the vehicle body, a rotating shaft 1 is fixedly mounted on the output end of the driving member 1 through a coupling, and gears respectively meshing with the two toothed discs are fixedly mounted on the outer side of the rotating shaft 1;

[0028] The auxiliary fixing mechanism includes two fixing sleeves respectively fixedly installed on the outside of the two threaded sleeves near the bottom end, a connecting piece 2 is rotatably installed on the outside of the fixing sleeve, and two articulated seats 3 are rotatably installed on the top of the vehicle body, a telescopic rod is hinged on the top of the articulated seat 3, and the top ends of the two telescopic rods are respectively rotatably connected to the adjacent connecting piece 2.

[0029] Furthermore, a pressure mechanism is installed in the support rod, and pressure pieces are slidably installed in the support rod and on both sides of the pressure mechanism, and the two pressure pieces have sides that are away from each other that penetrate the support rod and extend to the outside thereof;

[0030] Pressure agencies include:

[0031] A second driving member, which is fixedly mounted inside the supporting rod;

[0032] A second rotating shaft, which is fixedly mounted on the output end of the second driving member via a coupling;

[0033] A bidirectional eccentric wheel is slidably mounted on the outer side of the second rotating shaft and is capable of moving along its axial direction;

[0034] When the radar antenna is in the folded state, after the bidirectional eccentric wheel moves downward along the axial direction of the second rotating shaft to the limit stroke, it can apply a pressure along the length direction of the pressure pieces to the two pressure pieces. After the pressure pieces are subjected to the pressure, the pressure pieces transmit the pressure to the locking assembly, so that the static friction force generated between the pressure pieces and the locking assembly can prevent the pressure pieces and the locking assembly from moving relative to each other;

The top and bottom of the push rod are both provided with rotating balls. The rotating ball at the bottom contacts the top of the bidirectional eccentric wheel. The rotating ball at the top can contact the locking assembly on the radar antenna in the folded state. With the folding of the radar antenna, the locking assembly can apply a pressure along the axial direction of the push rod to the push rod. After the push rod is subjected to the pressure, the pressure is transmitted to the bidirectional eccentric wheel, so that the bidirectional eccentric wheel translates along the axial direction of the second rotating shaft.

[0039] Compared with the prior art, the radar antenna locking device provided by the present invention realizes increased stability by arranging two hydraulic rod assemblies in a symmetrical tilted shape; by tilting, the hydraulic rod will generate a horizontal component when subjected to force, and at the same time greatly reduces the lateral pressure on the hydraulic rod caused by the radar antenna due to sharp turns, large turns or bumps in driving, so that it is more firmly fixed on the vehicle body or supporting structure, thereby improving the overall stability; reducing deflection and deformation, especially in the case of long-distance support, this arrangement can effectively reduce deformation caused by deadweight or external loads; reducing pressure concentration, the tilted setting can disperse this pressure, reduce stress concentration of structural components, and thus extend their service life;

[0040] The threaded rod and the threaded sleeve are used to replace the hydraulic rod assembly to avoid the situation in which the two hydraulic cylinders are borne different loads due to sharp turns, large turns or bumps in the vehicle during the mission. For example, one hydraulic cylinder is subjected to greater resistance than the other, which directly leads to unbalanced loads on the two hydraulic rod assemblies and affects their movement speed and position. This ensures the locking support stability of the support assembly. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0061] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0062] Embodiment 1:

[0063] See also Figure 1 to Figure 2 and Figures 13 to 17 A radar antenna locking device is arranged in the rear compartment of a military radar vehicle. A power station is installed near the front of the vehicle in the rear compartment, and an antenna transceiver system - a radar antenna is installed on the top side of the vehicle away from the front of the vehicle. A liquid cooling system is installed on the top of the vehicle and between the power station and the radar antenna. Most of the radar antenna locking device is installed on the top of the vehicle body between the power station and the liquid cooling system, and the space occupied by the radar antenna is relatively small. It includes:

[0064] A support assembly 1, which is mounted on the top of the vehicle body;

[0065] The locking assembly 2 is installed on one side of the radar antenna on the top of the vehicle body, and can be connected to the supporting assembly 1 to lock and limit the radar antenna.

[0066] The support assembly 1 is a support rod vertically fixedly installed on the top of the vehicle body, perpendicular to the top of the vehicle body. The locking assembly 2 is a locking block fixedly installed on one side of the radar antenna. A slot that can be plugged into the top of the support assembly 1 is opened on one side of the locking block, so that when the radar antenna is in a folded state, the support rod can be inserted into the slot. The radar antenna in the folded state is locked and limited by the connection between the support rod and the locking block, so as to prevent the radar antenna from being displaced due to inertia or bumps when the vehicle makes a large or violent turn in the folded state, thereby damaging the connecting parts or the retraction and extension hydraulic rod of the radar antenna.

[0067] A pressure mechanism 15 is installed in the support rod, and pressure pieces 16 are slidably installed in the support rod and on both sides of the pressure mechanism 15. The two pressure pieces 16 penetrate the support rod and extend to the outside of the support rod. A friction pad (not shown in the figure) for increasing friction may be provided on the outward side of the pressure piece 16. A control module is also fixedly installed on one side of the support rod.

[0068] The pressure mechanism 15 comprises:

[0069] The second driving member 151 is fixedly mounted inside the support rod; the second driving member 151 includes but is not limited to a stepping motor or a servo motor, and is electrically connected to an external power supply and is also controlled by a control module. The second driving member 151 can drive the second rotating shaft 152 to rotate forward and reverse;

[0070] The second rotating shaft 152 is fixedly mounted on the output end of the second driving member 151 through a coupling;

[0071] A bidirectional eccentric wheel 153 is slidably mounted on the outer side of the second rotating shaft 152 and is capable of moving along its axial direction;

[0072] When the radar antenna is in the folded state, after the bidirectional eccentric wheel 153 moves downward along the axial direction of the second rotating shaft 152 to the limit stroke, it can apply a pressure along the length direction of the pressure pieces 16 to the two pressure pieces 16. After the pressure is applied, the pressure pieces 16 transmit the pressure to the locking assembly 2, so that the static friction force generated between the pressure pieces 16 and the locking assembly 2 can prevent the pressure pieces 16 and the locking assembly 2 from moving relative to each other.

[0073] The elastic member 154 is fixedly mounted on the top of the bidirectional eccentric wheel 153 and is slidably connected to the top of the inner cavity of the support rod; the elastic member 154 includes but is not limited to a spring or a folding spring plate;

[0074] The push rod 155 is vertically slidably mounted on the inner wall of the support rod near the top, and the top and bottom of the push rod 155 both penetrate the support rod. The top and bottom of the push rod 155 are provided with rotating beads, and the rotating bead at the bottom contacts the top of the bidirectional eccentric wheel 153. A pressure alarm connected to the rotating bead at the bottom is also fixedly installed in the push rod 155. The rotating bead at the top can contact the locking assembly 2 on the radar antenna in the folded state, and with the folding of the radar antenna, the locking assembly 2 can apply a pressure along the axial direction of the push rod 155 to the push rod 155. After being subjected to the pressure, the push rod 155 transmits the pressure to the bidirectional eccentric wheel 153, so that the bidirectional eccentric wheel 153 translates along the axial direction of the rotating shaft 152;

[0075] The output end of the pressure alarm is electrically connected to the input end of the control module, and the output end of the control module is electrically connected to the input end of the second driving element 151;

[0076] When the pressure value received by the pressure alarm in the push rod 155 exceeds the threshold value set therein, it sends an electrical signal to the control module, and the control module controls the second driving member 151 to drive the second rotating shaft 152 and the bidirectional eccentric wheel 153 to rotate and reset;

[0077] A connecting plate 156, which is fixedly mounted on the outer side of the second rotating shaft 152 and located below the bidirectional eccentric wheel 153;

[0078] Two traction ropes 157 are symmetrically fixedly mounted on the outside of the connection plate 156, and the ends of the two traction ropes 157 that are far away from each other are fixedly connected to the sides of the two pressure members 16 that are close to each other. The traction ropes 157 are tough ropes with a certain degree of elasticity.

[0079] When the radar antenna is folded, the locking assembly 2 gradually approaches the top of the support rod. As the radar antenna is folded, it contacts the top rod 155 in advance, and the radar antenna is continuously folded, so that pressure is applied to the top rod 155. After receiving the pressure, the top rod 155 slides downward and presses the bidirectional eccentric wheel 153. The bidirectional eccentric wheel 153 is forced to move downward along the axial direction of the second rotating shaft 152 and reaches between the two pressure members 16. When the locking assembly 2 is connected to the support rod, the user can start the second driving member 151. The second driving member 151 starts to drive the second rotating shaft 152 and the bidirectional eccentric wheel 153. The eccentric wheel 153 rotates on its own, and the two-way eccentric wheel 153 rotates on its own to push the two pressure pieces 16 to move away from each other along their respective length directions. The pressure piece 16 moves in parallel and is in close contact with the inner wall of the locking component 2, so as to achieve locking and fixing after the support component 1 and the locking component 2 are plugged in, thereby preventing the radar antenna from being lifted up due to the bumps of the vehicle. At the same time, the top rod 155 cooperates with the downward force of the two-way eccentric wheel 153 and the traction of the pressure piece 16 by the connecting plate 156 and the traction rope 157 on the rotating shaft 152, so as to avoid the problem that the radar antenna is about to be folded, but the radar antenna is used The user may mistakenly start the pressure mechanism 15 in advance to cause the pressure piece 16 to move out in advance, resulting in damage to the support assembly 1 and the locking assembly 2 when they are plugged in. This further avoids the problem that a pressure alarm is set on the pressure piece 16 to alarm when the pressure piece 16 is subjected to the pressure of the locking assembly 2 in order to avoid the above problem, resulting in the user having to first change the radar antenna from the folded state to the unfolded state to release the abutment between the pressure piece 16 and the locking assembly 2, and then retract the pressure piece 16, resulting in a decrease in the folding efficiency of the radar antenna. The force alarm is used to realize that when the user operates it incorrectly, the locking assembly 2 will contact the push rod 155 in advance, and the control module will control the driving member 151 to complete the resetting of the two-way eccentric wheel 153 to avoid the bottom of the two-way eccentric wheel 153 being squeezed with the tops of the two unextended pressure members 16. The push rod 155 will push the two-way eccentric wheel 153 between the two pressure members 16 after the resetting of the two-way eccentric wheel 153. At this point, the user can start the driving member 151 to drive the two-way eccentric wheel 153 to complete normal work, and there is no need to change the folding work of the radar antenna in this process.

[0080] Embodiment 2:

[0081] See also Figures 3 to 9 , a radar antenna locking device, the environment in which it is set is consistent with the first embodiment, and it includes:

[0082] A support assembly 1, which is mounted on the top of the vehicle body;

[0083] The locking assembly 2 is installed on one side of the radar antenna on the top of the vehicle body, and can be connected to the supporting assembly 1 to lock and limit the radar antenna.

[0084] The locking assembly 2 is an L-shaped frame fixedly mounted on one side of the radar antenna, and the support assembly 1 includes a locking auxiliary mechanism 12;

[0085] The locking auxiliary mechanism 12 comprises:

[0086] Two support sleeves 121;

[0087] The rotating shaft 122 has two ends connected to the inside of the two supporting sleeves 121 respectively;

[0088] The two inclined grooves 123 are symmetrically disposed on the outer side of the rotating shaft 122 .

[0089] The locking auxiliary mechanism 12 also includes:

[0090] Two fixing pins 124, which are respectively fixedly installed inside the two supporting sleeves 121, and are respectively slidably connected to the inner walls of the two inclined grooves 123;

[0091] The two connecting members 125 are rotatably mounted on ends of the two supporting sleeves 121 that are away from each other.

[0092] The locking auxiliary mechanism 12 also includes:

[0093] An eccentric block 126 is fixedly mounted on the outside of the rotating shaft 122 and located between the two supporting sleeves 121. The eccentric block 126 also abuts against one side of the locking assembly 2;

[0094] The rotating shaft 122 drives the eccentric block 126 to rotate, and the eccentric block 126 can apply a pressure along the width direction of the radar antenna to the locking assembly 2;

[0095] Two locking sleeves 127 are respectively fixedly mounted on ends of the two connecting members 125 that are away from each other.

[0096] The support assembly 1 also includes a diagonal support mechanism 11, which includes two hydraulic rod assemblies 111 distributed in a symmetrical and inclined state. The hydraulic rod assembly 111 is electrically connected to an external power supply, and the hydraulic rod assembly 111 includes but is not limited to an XYZ-1000 telescopic radar hydraulic rod or an ABC-500 high-precision telescopic hydraulic rod. The top ends of the two hydraulic rod assemblies 111 are hinged with an articulated seat 112.

[0097] Since the two hydraulic rod assemblies 111 are arranged in a symmetrical and inclined manner, it can also achieve:

[0098] Increased stability: The tilted hydraulic rod assembly 111 can reduce the lateral displacement of the hydraulic rod in the vertical direction. By tilting, the hydraulic rod will generate a horizontal component when subjected to force, and at the same time greatly reduce the lateral pressure on the hydraulic rod caused by the radar antenna due to sharp turns, large turns or bumps in driving, so that it is more firmly fixed on the vehicle body or supporting structure, thereby improving the overall stability.

[0099] Reduce deflection and deformation: The tilted hydraulic rod assembly 111 can reduce the bending and deflection of the hydraulic rod itself, especially in the case of long-distance support. This setting can effectively reduce the deformation caused by deadweight or external loads.

[0100] Reduce stress concentration: The upright vertical hydraulic rod will be subjected to greater pressure at the top in the above environment, while the inclined setting can disperse this pressure, reduce stress concentration on structural components, and thus extend their service life.

[0101] A turntable 113 rotatably connected to one side of the radar antenna is fixedly installed on one side of the two articulated seats 112, and the outer sides of the two hydraulic rod assemblies 111 near the top are rotatably connected to the inner sides of the two locking sleeves 127 respectively;

[0102] The bottom ends of the two hydraulic rod assemblies 111 are both hinged with hinged seats 114 2, and one side of the two hinged seats 114 is fixedly mounted with turntables 115 rotatably connected to the top of the vehicle body.

[0103] When the user has to unfold the radar antenna to drive the vehicle due to mission requirements, the hydraulic rod assembly 111 is activated to cooperate with the hinge seat 1 112 and the turntable 1 113 to connect and support the top of one side of the radar antenna, and the hydraulic rod assembly 111 cooperates with the hinge seat 2 114 and the turntable 2 115 to connect the top of the vehicle body to serve as the bottom support;

[0104] At the same time, along with the extension and retraction of the hydraulic rod assembly 111, it will drive the locking sleeve 127 thereon to move. Because of the inclined setting of the hydraulic rod assembly 111, its extension and retraction will cause the relative angle between the two to change. The two locking sleeves 127 will drive the two supporting sleeves 121 to move closer or away from each other through the connecting piece 125. The two supporting sleeves 121 will move closer or away from each other, and the fixing nails 124 therein will cooperate with the inclined groove 123 to drive the rotating shaft 122 and the eccentric block 126 to rotate. The rotation of the eccentric block 126 will abut and synchronously apply pressure to the locking assembly 2, so that the locking assembly 2 drives the radar antenna to be locked and fixed, so as to achieve the situation of "double-sided abutment", so as to avoid the radar antenna from tilting forward due to the bumps of the vehicle, and the diagonal support mechanism 11 cannot effectively pull and fix the radar antenna due to the hinge seat 112 and the turntable 113.

[0105] Embodiment three:

[0106] See also Figures 6 to 12 , a radar antenna locking device, the environment in which it is set is consistent with the first embodiment, and it includes:

The outer side of the threaded rod 132 is threadedly connected to the threaded sleeve 131, and the threaded sleeve 131 is located above the threaded rod 132. The bottom end of the threaded rod 132 is fixedly installed with a universal joint end 133, and the bottom of the universal joint end 133 is connected to a universal joint end 2 134 through a cross shaft 135.

[0124] The top ends of the two threaded sleeves 131 are both hinged with hinged seats 4, and one side of the two hinged seats 4 is fixedly mounted with a turntable 3 that is rotatably connected to one side of the radar antenna.

[0128] The threaded rod 132 cooperates with the threaded sleeve 131 to replace the hydraulic rod assembly 111 in the second embodiment in order to achieve:

[0129] Avoid situations in which the loads on the two hydraulic cylinders are different due to sharp turns, large turns or bumps during the mission, for example, the resistance on one hydraulic cylinder is greater than that on the other, which directly causes the two hydraulic rod assemblies 111 to bear unbalanced loads, affecting their moving speed and position;

[0130] Mechanical activity is used instead of hydraulic transmission to achieve effective locking and support of the radar antenna.

[0131] At the same time, along with the translation of the threaded sleeve 131, it will drive the locking sleeve 127 thereon to move. Because of the inclined setting of the threaded sleeve 131, its expansion and contraction will cause the relative angle between the two to change. The two locking sleeves 127 will drive the two supporting sleeves 121 to move closer or away from each other through the connecting piece 125. The two supporting sleeves 121 will move closer or away from each other and will drive the rotating shaft 122 and the eccentric block 126 to rotate through the fixing nails 124 therein and the inclined groove 123. The rotation of the eccentric block 126 will abut and synchronously apply pressure to the locking component 2, so that the locking component 2 drives the radar antenna to be locked and fixed, so as to achieve the "double-sided abutment" situation, so as to avoid the radar antenna from tilting forward due to the bumps of the vehicle, and the problem that the diagonal support mechanism 2 13 cannot effectively pull and fix the radar antenna due to the hinge seat 4 and the turntable 3.
