Description

Technical Field

[0001] This invention relates to the field of turret technology, and more particularly to a turret with a shaft locking mechanism. Background Technology

[0002] With the continuous breakthroughs and development of optoelectronic technology in my country, more and more turrets are being used in unattended areas, becoming more modern and intelligent. This has led to increasingly higher reliability requirements for optoelectronic turrets. In the face of severe weather conditions such as storms and heavy rain, the turret's azimuth and pitch axes are typically locked manually. (Note: Here, azimuth refers to the axial rotation around the mounting surface, defined as the azimuth axis; the rotation axis perpendicular to the azimuth axis is the pitch axis). To ensure a wide field of vision for the turret equipment, most equipment along the border and coastal defense lines in China is installed at high altitudes and far from outposts. Locking the turrets in harsh environments presents numerous inconveniences, being time-consuming, labor-intensive, and inefficient. Summary of the Invention

[0003] This invention provides a turret with a shaft locking mechanism to solve the problem of time-consuming and labor-intensive turret locking operations in harsh environments in the prior art.

[0004] The turret with a shaft locking mechanism according to an embodiment of the present invention includes:

[0005] U-shaped frame;

[0006] The load compartment is rotatably connected to the U-shaped frame via a pitch rotation axis;

[0007] A locking rod is fixed to the pitch rotation axis, and the free end of the locking rod has a locking hole;

[0008] A locking mechanism is installed on the U-shaped frame. The locking mechanism includes a base, a pressure cover, an electric push rod, a switch adjustment bracket, a first photoelectric switch, a second photoelectric switch, and a locking rod. The pressure cover is connected to the base to define an installation space. The electric push rod is installed in the installation space, and the driving end of the electric push rod extends out of the installation space through a first through hole on the base. The locking rod includes a connecting rod and a locking rod. One end of the connecting rod is connected to the driving end of the electric push rod, and the other end of the connecting rod is perpendicularly connected to the middle section of the locking rod. A light-blocking plate is provided on the first section of the locking rod located on one side of the connecting rod. The switch adjustment bracket is installed on the top of the pressure cover. The first photoelectric switch and the second photoelectric switch are installed on the switch adjustment bracket and are arranged at intervals along the extension direction of the first section. The straight-line distance between the centers of the first photoelectric switch and the second photoelectric switch is equal to the length of the light-blocking plate.

[0009] The electric actuator is used to receive a first locking command and drive the locking rod to move according to the first locking command, so that the locking rod switches between an initial position and a locked position; when the locking rod is in the locked position, the light-blocking plate does not block the first photoelectric switch and the second photoelectric switch, and the end of the second segment on the locking rod located on the other side of the connecting rod is located inside the lock hole; when the locking rod is in the initial position, the light-blocking plate blocks the first photoelectric switch and the second photoelectric switch, and the end of the second segment is located outside the lock hole; when the locking rod is between the initial position and the locked position, the light-blocking plate blocks one of the first photoelectric switch and the second photoelectric switch, and the end of the second segment is located outside the lock hole;

[0010] A drive control unit is used to receive a second locking command and drive the pitch rotation axis or the U-shaped frame according to the second locking command so that the locking hole and the locking rod are coaxial;

[0011] A control device is communicatively connected to the first photoelectric switch and the second photoelectric switch. The control device is used to receive signals returned by the first photoelectric switch and the second photoelectric switch to determine the position of the locking rod, and to determine the current state of the turret based on the position of the locking rod.

[0012] When the locking lever is in the locked position, the turret is determined to be in a locked state; when the locking lever is in the initial position, the turret is determined to be in an unlocked state; when the duration between the initial position and the locked position exceeds a preset time, the turret is determined to be in a fault state and a warning signal is issued.

[0013] Using the embodiments of the present invention, the locking of the turret can be remotely controlled, which increases convenience for soldiers at the outpost and saves time and effort.

[0024] Exemplary embodiments of the invention will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the invention are shown in the drawings, it should be understood that the invention can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided to enable a more thorough understanding of the invention and to fully convey the scope of the invention to those skilled in the art. Furthermore, in some instances, well-known methods, structures, and techniques have not been shown in detail so as not to obscure the understanding of this specification.

[0025] Reference Figure 3 , Figure 4 As shown, the turret with a shaft locking mechanism according to an embodiment of the present invention includes:

[0026] 10 U-shaped frames;

[0027] The load compartment is rotatably connected to the U-shaped frame 10 via the pitch rotation shaft 11;

[0028] Locking rod 9 is fixed to pitch rotation shaft 11, and the free end of locking rod 9 has a locking hole;

[0029] The locking mechanism is installed on the U-shaped frame 10.

[0030] Reference Figure 1 , Figures 6-8As shown, the locking mechanism includes a base 1, a pressure cap 3, an electric actuator 2, a switch adjustment bracket 4, a first photoelectric switch 5, a second photoelectric switch 6, and a locking rod 7. The pressure cap 3 is connected to the base 1 to define an installation space. The electric actuator 2 is installed in the installation space, and the driving end of the electric actuator 2 extends out of the installation space through a first through hole on the base. The pressure cap 3 and the base 1 are designed separately to facilitate the installation and removal of the electric actuator 2.

[0031] The locking lever 7 is T-shaped and includes a connecting rod and a locking lever. One end of the connecting rod is connected to the drive end of the electric push rod 2, and the other end is perpendicularly connected to the middle section of the locking lever. The connecting rod acts as a transition, transmitting driving force. A light-blocking plate is provided on the first section of the locking lever located on one side of the connecting rod. The light-blocking plate acts on the first photoelectric switch 5 and the second photoelectric switch 6. The switch adjustment bracket 4 is installed on the top of the pressure cover 3. The first photoelectric switch 5 and the second photoelectric switch 6 are installed on the switch adjustment bracket 4 and are spaced apart along the extension direction of the first section. The straight-line distance between the centers of the first photoelectric switch 5 and the second photoelectric switch 6 is equal to the length of the light-blocking plate. During the movement of the first section, the signals detected by the first photoelectric switch 5 and the second photoelectric switch 6 change due to the action of the light-blocking plate. By combining the signals detected by the first photoelectric switch 5 and the second photoelectric switch 6, the position of the first section can be determined, thereby determining the current state of the locking structure.

[0032] The electric actuator 2 is used to remotely receive the first locking command issued by the user and drive the locking lever 7 to move according to the first locking command, so that the locking lever 7 switches between the initial position and the locked position; when the locking lever 7 is in the locked position, the light-blocking plate does not block the first photoelectric switch 5 and the second photoelectric switch 6, and the end of the second section on the other side of the connecting rod of the locking lever is located in the lock hole, as shown in the reference. Figure 6 As shown; when the locking lever 7 is in the initial position, the light-blocking plate blocks the first photoelectric switch 5 and the second photoelectric switch 6, and the end of the second segment is outside the lock hole, as shown in the figure. Figure 7 As shown; when the locking lever 7 is between the initial position and the locked position, the light-blocking plate blocks one of the first photoelectric switch 5 and the second photoelectric switch 6, and the end of the second segment is outside the lock hole, as shown in the reference. Figure 8 As shown; if the installation positions of the first photoelectric switch 5 and the second photoelectric switch 6 are Figure 1 As shown, when the locking lever 7 is between the initial position and the locked position, the light-blocking plate only blocks the second photoelectric switch 6, and at this time the end of the second segment is outside the lock hole.

[0033] A drive control unit is used to receive a second locking command and drive the pitch rotation axis 11 or the U-shaped frame 10 according to the second locking command so that the lock hole and the lock rod are coaxial.

[0034] The control device is communicatively connected to the first photoelectric switch 5 and the second photoelectric switch 6. The control device receives signals returned by the first photoelectric switch 5 and the second photoelectric switch 6 to determine the position of the locking lever 7, and determines the current state of the turret based on the position of the locking lever 7. When the locking lever 7 is in the locked position, the turret is determined to be in the locked state. Figure 4 As shown; when locking lever 7 is in the initial position, the turret is determined to be in the unlocked state, as... Figure 3 As shown; when the duration between the initial position and the locked position of the locking lever 7 exceeds the preset time, the turret is determined to be in a fault state and a warning signal is issued.

[0035] The "preset duration" mentioned here can be set according to the actual situation. For example, the preset duration can be 2s, 3s, 4s, 5s, 6s, etc.

[0036] By employing the embodiments of the present invention, the locking of the turret can be remotely controlled through the cooperation of the locking rod and the locking mechanism, which increases convenience for soldiers at the outpost and saves time and effort.

[0037] Based on the above embodiments, further variant embodiments are proposed. It should be noted that, in order to keep the description brief, only the differences from the above embodiments are described in each variant embodiment.

[0038] According to some embodiments of the present invention, the control device is used to send a second locking command to the drive control element;

[0039] The drive controller is communicatively connected to the electric actuator 2. The drive controller sends a first locking command to the electric actuator 2 after the locking hole and locking rod are coaxial. Thus, the user can issue a second locking command, and the drive controller can automatically issue the first locking command to the electric actuator 2 after completing rotation control.

[0040] During implementation, the drive control unit can use sensors to detect the current position of the load chamber and the U-shaped frame 10 to determine the required rotation angle of the pitch axis 11 or the U-shaped frame 10, thereby driving the pitch axis 11 or the U-shaped frame 10 to make the locking hole and the locking rod coaxial. Furthermore, after further confirming that the locking hole and the locking rod are coaxial, the sensor can issue a first locking command to the electric actuator 2.

[0041] According to some embodiments of the present invention, the control device is configured to: send a second locking command to the drive control component and receive feedback from the drive control component; and after determining that the lock hole and the lock rod are coaxial, send a first locking command to the electric push rod 2.

[0042] like Figure 1 , Figures 6-8 As shown, according to some embodiments of the present invention, the turret with a shaft locking mechanism further includes:

[0043] Guide seat 8 is connected to base 1. The inside of guide seat 8 defines a movement space and is provided with mounting holes, through holes and guide channels.

[0044] The locking rod 7 is located in the movement space. The mounting hole is used to connect the connecting rod to the drive end of the electric push rod 2. The first section passes through the through hole, and the second section passes through the guide channel.

[0045] The guide seat 8 plays a protective role for the locking mechanism. When the turret is subjected to strong external force, the guide seat 8 bears the impact force and protects the locking mechanism from damage.

[0046] Furthermore, when the keyhole and the lock rod are coaxial, the distance between the end face of the guide channel and the end face of the keyhole is less than 1 cm. In practical design, the end face of the guide channel can be made almost identical to the end face of the keyhole, such as... Figure 4 As shown.

[0047] By extending the guide seat 8, the design allows the guide seat 8 to bear the entire force on the locking rod 7 when it is subjected to external force (human force or strong wind causing the turret to rotate, and the tangential force generated by the lock hole on the locking rod). (Usually, in the structural design of the shaft hole, in order to ensure that the locking rod can extend and retract freely, it needs to be designed with a clearance fit. At this time, the locking rod will be displaced in the clearance fit when subjected to tangential force. The magnitude of the displacement of the push rod is determined by the length of the guide. Under the condition of the same clearance, the longer the guide, the smaller the angle between the locking rod and the guide, and thus the smaller the displacement. The locking rod contacts the guide seat, thereby transferring the tangential force to the guide seat.) This design cleverly transfers the tangential force to the guide seat 8, so that it cannot be transmitted to the electric push rod 2 and the locking rod 7, thus preventing damage to the electric push rod 2 and the locking rod 7.

[0048] Furthermore, the choice of materials for the guide seat 8 and the locking rod 7 is also necessary. For example, in some embodiments of the present invention, the locking rod 7 is made of steel and the guide seat 8 is made of copper. Copper has self-lubricating properties and will not wear out even after long-term use, which is also a means of maintenance-free design.

[0049] According to some embodiments of the present invention, the electric actuator 2 has a power-off self-locking function. Even when the system is powered off and subjected to impact vibration, the locking rod 7 will not slip, maintaining performance stability. Through a clever combination of structure and electrical design, a self-protective redundant design is achieved, improving reliability.

[0050] like Figure 5 As shown, according to some embodiments of the present invention, the end of the second segment is rounded;

[0051] The keyhole has a guide groove.

[0052] According to some embodiments of the present invention, the mounting positions of the first photoelectric switch 5 and the second photoelectric switch 6 on the switch adjustment bracket 7 are adjustable. Therefore, after the locking rod 7 is installed, the mounting positions of the first photoelectric switch 5 and the second photoelectric switch 6 on the switch adjustment bracket 7 can be adjusted, facilitating assembly.

[0053] According to some embodiments of the present invention, epoxy resin adhesive is filled into the mounting space to fix the electric actuator 2. This improves the stability of the electric actuator 2.

[0054] According to some embodiments of the present invention, the locking rod is located inside the pitch rotation shaft, and the locking mechanism is located inside the U-shaped frame. This avoids long-term damage from rain and wind, rust, and other problems, achieving true maintenance-free operation.

[0055] According to some embodiments of the present invention, one end of the connecting rod is connected to the driving end of the electric push rod 2 through a flat pin groove structure, which can ensure that the locking rod 7 is tightly connected to the electric push rod 2.

[0056] The turret with a shaft locking mechanism according to an embodiment of the present invention will now be described in detail with reference to the accompanying drawings and a specific example. It is to be understood that the following description is merely exemplary and should not be construed as a specific limitation of the invention.

[0057] The purpose of this invention is to design a turret shaft locking mechanism with feedback function, which can provide feedback prompts on whether the locking is completed before, during, and after locking; and a highly reliable structural design that protects the internal locking drive components from damage when the locking rod is subjected to a strong impact, enabling remote locking of the turret in the face of severe weather, timely protection of the equipment, and improved efficiency.

[0058] The turret shaft locking mechanism with position feedback according to an embodiment of the present invention consists of an electric actuator, a locking rod, a guide seat, an optical switch, and a control circuit. By designing a dual-light switch arrangement, unlocking, locking, and detection of abnormalities during operation are achieved, improving locking reliability. The two light switches are mounted on a mechanically adjustable bracket, and the locking position is controlled by adjusting the bracket's stroke. A light-blocking plate is designed on the locking rod, its length precisely matching the straight-line distance between the centers of two adjacent light switches. This design enables precise feedback: if both light switches are simultaneously blocked by the plate, the locking rod is in the retracted state, with its front end flush with the guide seat; if one light switch is blocked and the other is not, it is in the intermediate state. The locking and unlocking time is designed to be 2 seconds; if it exceeds 4 seconds, an abnormality in the locking mechanism is detected and reported. If both switches are unblocked, the locking mechanism is in the locked state. The locking rod is driven by an electric actuator, achieving the locking function under the constraint of the guide seat. The electric actuator has a self-locking function, thus enabling power-off self-locking. Even under power failure and impact vibration, the locking rod will not slip, maintaining performance stability. By cleverly combining structural and electrical design, a self-protective redundant design is achieved, thereby improving reliability.

[0059] By extending the guide seat's structural design, when the locking rod is subjected to external force (human intervention or strong winds causing the turret to rotate, and the tangential force generated by the lock hole on the locking rod), the extended guide structure design allows the guide seat to bear all the force on the locking rod. (Usually, in the structural design of the shaft hole, to ensure that the locking rod can extend and retract freely, a clearance fit is required. In this case, the locking rod will be displaced by the tangential force, and the magnitude of the displacement is determined by the length of the guide. Under the same clearance condition, the longer the guide, the smaller the angle between the locking rod and the guide, and thus the smaller the displacement. The locking rod contacts the guide seat, thereby transferring the tangential force to the guide seat.) This design cleverly transfers the tangential force to the guide seat, preventing it from being transmitted to the drive components and thus preventing damage to the drive components. Furthermore, the choice of materials for the guide seat and locking rod is also crucial. The locking rod is made of steel, and the guide seat is made of copper. Copper has self-lubricating properties and will not wear out even after long-term use, which is also a means of maintenance-free design.

[0060] The embodiments of the present invention also include a lock hole structure. The lock hole part works with the locking mechanism to achieve the above functions. When in use, the locking mechanism needs to be installed on the side wall of the U-shaped frame, and the lock hole structure is installed on a specific structure of the turret pitch and rotation axis system to achieve the axis system locking function.

[0061] In this embodiment of the invention, the locking mechanism has a self-locking effect, being energized only during locking and unlocking, and disconnected afterward. Even when the system is powered off, the locking mechanism will not fail, maintaining the locked / unlocked state. A dual photoelectric switch arrangement and adjustable switch position are employed. Logic analysis of the rising or falling edges determines whether the current locking state is locked, unlocked, or abnormal. An extended guide seat design is used; when subjected to strong external forces, the guide seat absorbs the impact force, protecting the locking drive assembly from damage. Maintenance-free operation is achieved through the selection of materials for the locking rod and guide seat.

[0062] Detailed, such as Figure 1 As shown, the turret locking mechanism with position feedback includes: base 1, electric push rod 2, pressure cover 3, switch adjustment bracket 4, photoelectric switch 5, photoelectric switch 6, locking rod 7, guide seat 8, lock hole rod 9, U-shaped frame 10, and rotating shaft 11.

[0063] The electric actuator 2 is installed inside the base 1. Epoxy resin is poured around the base 1 to ensure a tight connection between the base 1 and the electric actuator 2. A pressure cap 3 is installed on the upper part of the base 1 and fixed with screws. The pressure cap 3 serves two purposes: firstly, it presses the electric actuator 2 firmly, and secondly, it provides a mechanical interface for the adjustment bracket 4. A locking rod 7 is then connected and fixed to the electric actuator 2 with screws. To prevent slippage of the locking rod 7, the mounting surface between the locking rod 7 and the electric actuator 2 is designed with a flat pin groove structure. Figure 2 As shown, this ensures a tight connection between the locking rod 7 and the electric push rod 2. Apply lubricant around the locking rod 7, insert the guide seat 8 into the locking rod 7, and then install it on the base 1 and secure it with screws. Install photoelectric switches 5 and 6 on the adjusting bracket 4 and tighten them with screws. Pre-fix the previously installed adjusting bracket 4 (with photoelectric switches 5 and 6 mounted on it) and the base; the screws do not need to be tightened. Use the drive circuit to extend the locking rod 7 to its limit position and pause. At this point, move the adjusting bracket 4 so that the center of photoelectric switch 6 is blocked by the light-blocking plate at the rear end of the locking rod 7. Note: The mounting hole of the adjusting bracket 4 is an oblong hole, allowing movement along the groove direction. Tighten the adjusting bracket 4 with screws. Test the unlocked state by using the drive circuit to control the locking rod 7 to retract. When the light-blocking plate at the rear end of the locking rod 7 simultaneously blocks the center parts of photoelectric switches 5 and 6, the locking assembly will then feedback to lock.

[0064] The locking mechanism is mounted on the side wall of the U-shaped frame 10 via its own mechanical interface, perpendicular to the pitch rotation axis, with the load compartment positioned along the viewing direction as shown. Figure 3As shown, rotate it 90° clockwise to set it to the locked position (the optical window is hidden at the bottom of the U-shaped frame 10 for protection). Install the locking rod 9 on the rotating shaft 11 of the pitch axis system. The locking rod is connected to the shaft using a stop fit and is fixed to the rotating shaft 11 with screws (the load chamber and the rotating shaft 11 rotate synchronously). This ensures that after the load chamber has rotated 90°, the locking hole of the locking rod 9 is coaxial with the locking rod 7 of the locking mechanism. Figure 4 As shown, the detailed structure of the lock hole rod is as follows: Figure 5 As shown. At this point, the turntable encoder records this angle status position and sets it to the locked position. After the locking signal is issued, the load chamber will rotate to the locked position regardless of its angle. Figure 4 The lock is positioned as shown, and then the locking action is performed. At this time, the locking rod is inserted into the guide groove of the lock hole rod 9, and the tilt and lock of the turntable is completed. It is particularly important to note that when installing the locking mechanism to the side wall of the U-shaped frame, it is necessary to ensure that the lock hole of the lock hole rod 9 and the locking rod 7 of the locking mechanism are installed coaxially. This is achieved by the following method: fix the position of the load compartment after rotating it 90° clockwise along the visual direction, and move the position of the locking mechanism to achieve the coaxiality of the locking rod 7 with the lock hole rod. This ensures that the extension and retraction of the locking rod 7 in both locking and unlocking states do not affect the rotation of the rotating shaft 11.

[0065] like Figure 6 As shown, when the locking mechanism is in the locked state, the light-blocking plate at the rear end of the locking lever 7 is located to the right of the center of the photoelectric switch 6. During the locking process, the driving circuit chip will detect two rising edge transitions and eventually maintain a high level, indicating that the locking mechanism is locked and successfully locked.

[0066] like Figure 7 As shown, when the locking mechanism is in the unlocked state, the light-blocking plate at the rear end of the locking rod 7 is located to the left of the center of the photoelectric switch 5. At this time, the unlocking is complete. During this process, the driving circuit chip will go from a high level to experience two falling edge transitions and finally remain at a low level, indicating that the locking mechanism is unlocked and successfully unlocked.

[0067] like Figure 8 As shown, when the locking mechanism is in an abnormal state, the light-blocking plate at the rear end of the locking lever 7 is located in the center of the photoelectric switch 5 and the center area of ​​the photoelectric switch 6. During this process, the drive circuit chip will only experience one transition from high level to low level, and there will be no two transitions after the unlocking and locking time has expired, indicating that the locking is faulty at this time.

[0068] In this embodiment of the invention, a locking mechanism with feedback is installed on the pitch and azimuth axes. When locking is required, a remote command can be issued to achieve the remote locking function (which requires the use of a control circuit; this invention focuses on the structural design). Moreover, this mechanism has an automatic feedback protection mechanism that can automatically provide a prompt if the lock is not in place, improving the stability of remote locking. This increases convenience for soldiers at outposts, saving time and effort. Furthermore, since the locking components are located inside the device, compared to traditional external locking mechanisms, it can avoid long-term exposure to rain and wind erosion, rust, and other problems, truly achieving maintenance-free operation.
