DETAILED DESCRIPTION

[0032] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the embodiments and the accompanying drawings. Here, the illustrative embodiments of the present invention and their descriptions are used to explain the present invention, but are not intended to limit the present invention.

[0034] It should be emphasized that the term “include / comprises” when used herein refers to the presence of features, elements, steps or components, but does not exclude the presence or addition of one or more other features, elements, steps or components.

[0035] It should also be noted that, unless otherwise specified, the term “connection” herein may refer not only to a direct connection but also to an indirect connection involving an intermediate.

[0036] Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. In the accompanying drawings, the same reference numerals represent the same or similar components, or the same or similar steps.

[0037] Reference Figure 1 and Figure 2 , an embodiment of the present invention provides a device for automatically releasing a positioning block in a closed space of an aircraft lock ring station, comprising: a frame 1, and a rotating shaft mechanism, a linear drive mechanism, a leveling release mechanism and a control component arranged on the frame 1;

[0038] Among them, the rotating shaft mechanism includes a rotating shaft 2 and a fixing part 3, one end of the rotating shaft 2 is rotatably connected to the frame 1, and the middle part of the rotating shaft 2 is fixedly connected to the external device through the fixing part 3; the linear drive mechanism is fixedly connected to the top of the frame 1, and the linear drive mechanism is connected to the leveling release mechanism, which is used to drive the leveling release mechanism to move in the vertical direction; the leveling release mechanism includes a leveling sleeve 4 and a push rod 5 and a first spring 6 arranged inside the leveling sleeve 4; the leveling sleeve 4 is vertically slidably connected to the bottom of the frame 1, the push rod 5 is connected to the linear drive mechanism, the first spring 6 is arranged between the leveling sleeve 4 and the push rod 5, and the first spring 6 is used to push the leveling sleeve 4 downward during the downward movement of the push rod 5, and a positioning block is installed at the bottom of the leveling sleeve 4.

[0039] In the above embodiment, by integrating the linear drive mechanism, the leveling release mechanism and the control assembly, the device can automatically complete the release process of the positioning block without manual intervention, thereby improving work efficiency and automation level. The design of the leveling release mechanism, especially the vertical sliding connection between the leveling sleeve 4 and the bottom of the frame 1, and the setting of the first spring 6, ensure the stability and accuracy of the positioning block during the release process. This design helps to reduce positioning errors and improve the positioning accuracy of the positioning block.

[0040] The shaft mechanism is fixedly connected to the external device through the fixing member 3. This design allows the device to easily adapt to the lock ring stations of aircraft of different models and specifications, thereby improving the versatility and flexibility of the device. The integration of the control components makes the operation easier. The user can drive the linear drive mechanism through simple control instructions, thereby controlling the action of the leveling release mechanism, thereby achieving precise control of the release process of the positioning block.

[0041] It should be noted that the linear drive mechanism drives the push rod 5 to move downward, and the push rod 5 transmits the thrust to the first spring 6. The first spring 6 pushes the leveling sleeve 4 downward until it contacts the reference plane. When a certain point or edge line at the bottom of the leveling sleeve 4 contacts the reference plane, the linear drive mechanism continues to move downward. At this time, the frame 1 rotates around the rotating shaft 2 until the bottom surface of the leveling sleeve 4 is completely in contact with the reference plane, thereby achieving the leveling effect; the linear drive mechanism continues to move downward to drive the push rod 5 to push out the positioning block 15 installed at the bottom of the leveling sleeve 4. A tape is provided at the bottom of the positioning block 15, which can make the positioning block 15 firmly adhere to the reference plane, thereby achieving the effect of fixing the positioning block 15.

[0042] The overall structure of the device is compact and occupies little space, and is suitable for use in the enclosed space of the aircraft lock ring station. This compact structural design not only improves space utilization, but also helps to reduce installation and maintenance costs. Through reasonable mechanism design and component selection, the device can maintain good stability and reliability during long-term use. In particular, the setting of the first spring 6 not only helps the smooth movement of the leveling sleeve 4, but also absorbs and buffers external shocks and vibrations to a certain extent, thereby improving the durability and service life of the device.

[0043] In some embodiments, reference Figure 3 The bottom surface of the leveling sleeve 4 is a plane, and the leveling sleeve 4 has a first cavity 7 and a second cavity 8. The first cavity 7 and the second cavity 8 are connected, and the first cavity 7 is arranged above the second cavity 8. The first cavity 7 and the second cavity 8 are connected. The first step is arranged at the junction of the first cavity 7 and the second cavity 8, and the top of the push rod 5 is arranged at the second step. The upper and lower ends of the first spring 6 are respectively connected to the first step and the second step. The bottom of the push rod 5 can pass through the junction of the first cavity 7 and the second cavity 8 to push out the positioning block 15, and the second cavity 8 is used to install the positioning block.

[0044] In the above embodiment, the bottom surface of the leveling sleeve 4 is designed to be a plane, which ensures stability and accuracy when contacting with the aircraft lock ring station. When the positioning block needs to be released, the leveling sleeve 4 can provide a stable reference surface to ensure that the positioning block can be accurately placed in the predetermined position. The upper and lower ends of the first spring 6 are respectively connected to the first step of the leveling sleeve 4 and the second step of the push rod 5. This arrangement not only ensures the stability of the spring during compression and release, but also effectively absorbs and buffers the impact force generated when the push rod 5 moves, thereby extending the service life of the device.

[0045] The bottom of the push rod 5 can pass through the joint of the first cavity 7 and the second cavity 8. This design allows the push rod 5 to push the positioning block out of the second cavity 8 under the drive of the linear drive mechanism. This flexible push rod design ensures that the positioning block can be quickly and accurately released to the predetermined position.

[0046] In some embodiments, reference Figure 4 The bottom of the leveling sleeve 4 is provided with a clamping structure, which includes a fixed plate 9, a stopper 10 and a second spring 11. The stopper 10 is slidably connected with the fixed plate 9 in a transverse direction, the second spring 11 is arranged between the fixed plate 9 and the stopper 10, the edge of the fixed plate 9 is fixedly connected with the edge of the leveling sleeve 4, and the stopper 10 is located inside the leveling sleeve 4.

[0047] In the above embodiment, the introduction of the clamping structure, especially the lateral sliding connection between the stopper 10 and the fixing plate 9, and the provision of the second spring 11, provide a more stable fixing method for the positioning block. Before the positioning block is ejected, the stopper 10 will tightly clamp the positioning block under the action of the second spring 11 to prevent it from accidentally falling off in a non-released state. When the push rod 5 pushes the positioning block, the stopper 10 will slide laterally under the action of external force, thereby smoothly releasing the positioning block. This design greatly enhances the stability of the positioning block during the fixing and releasing process. The lateral sliding connection between the stopper 10 and the fixing plate 9 enables the stopper 10 to be flexibly moved as needed to adapt to positioning blocks of different sizes and shapes. This design improves the versatility and adaptability of the device, making it applicable to more types of aircraft lock ring stations.

[0048] The setting of the second spring 11 not only provides the necessary elastic force for the stopper 10, but also plays a buffering role during the movement of the stopper 10, reducing the impact of impact and vibration on the device. This optimized spring arrangement helps to improve the service life and stability of the device. The connection structure is cleverly integrated at the bottom of the leveling sleeve 4 without adding additional space. This compact structural design makes the device more compact and lightweight as a whole, and is convenient for use in the enclosed space of the aircraft lock ring station. The design of the snap-fit ​​structure makes the installation, fixing and release process of the positioning block simpler and more intuitive. The user only needs to put the positioning block into the leveling sleeve 4, and the snap-fit ​​structure will automatically fix it; when the positioning block needs to be released, it can be achieved by pushing the push rod 5. This simplified operation process reduces the difficulty of operation and improves work efficiency.

[0049] In some embodiments, the rotating shaft 2 has a straight section and a connecting section, the straight section and the connecting section are connected, the straight section is rotatably connected to the frame 1, and the connecting section is fixedly connected to an external device through a fixing member 3. The straight section and the connecting section are arranged at an angle of 15 to 75 degrees.

[0050] In the above embodiment, the rotating shaft 2 is designed to include a straight section and a connecting section. This design enables the rotating shaft 2 to distribute stress more evenly when subjected to external loads, thereby enhancing its structural stability and durability. The rotational connection between the straight section and the frame 1 ensures the stability and reliability of the rotation, while the connecting section is closely connected to the external device through the fixing member 3, further improving the overall stability.

[0051] The design of the connecting section enables the shaft 2 to be flexibly connected to external equipment. This flexibility not only facilitates the installation and disassembly of the device, but also enables the device to adapt to external equipment of different models and specifications, thereby improving the versatility and adaptability of the device. By designing the shaft 2 as a structure in which a straight section and a connecting section are connected, space can be used more reasonably, making the device more compact as a whole. This compact layout not only reduces the occupied space, but also helps to improve the convenience and efficiency of the operation of the device at the aircraft lock ring station.

[0052] In some embodiments, the end of the straight section is sleeved with a rotating sleeve 12, the rotating sleeve 12 is rotatably connected to the straight section, and the rotating sleeve 12 is fixedly connected to the frame 1 through screws. The rotating sleeve 12 provides a good rotation effect for the rotation of the straight section and the frame 1.

[0053] In some embodiments, a limit block 13 is provided at the joint of the straight section and the connecting section, and the limit block 13 has a vertical plane, and the vertical plane is in contact with the frame 1. The limit block 13 can increase the lateral support force of the rotating shaft on the frame.

[0054] In some embodiments, the linear drive mechanism includes any one of a linear motor 14 , a cylinder, and an electric push rod 5 .

[0055] In some embodiments, two second springs 11 are provided, and the two second springs 11 are located on both sides of the fixing plate 9. Such an arrangement allows the fixing plate 9 and the stopper 10 to be subjected to uniform force.

[0056] Reference Figure 5 and Figure 6 In some embodiments, the control component includes a mainboard, a battery and a control button, and the mainboard, the battery and the control button are electrically connected to each other; the mainboard is provided with an onboard charging management chip, a discharge LDO linear regulator, a three-color light, a passive buzzer, a DCDC boost module, EMC protection, a fuse, a Type-C interface and a magnetic charging interface; the battery is installed on the frame 1; the control button includes a power switch button, a start button and a reset button.

[0057] In the above embodiment, the control component highly integrates the battery, control buttons and other key electronic components through the mainboard to achieve intelligent control. This design not only simplifies the circuit structure, improves the stability and reliability of the system, but also makes the operation more convenient and intuitive.

[0058] The onboard charge management chip and discharge LDO linear regulator on the mainboard ensure safe charging and stable discharge of the battery. At the same time, the DCDC boost module provides a flexible voltage conversion function to meet the different voltage requirements of different electronic components. These designs together ensure the power stability and endurance of the device during long-term use.

[0059] The three-color light and passive buzzer provide intuitive status indication and alarm functions for the device. Users can judge the working status of the device or whether there is a fault by observing the color changes of the three-color light or listening to the sound of the passive buzzer, so as to take corresponding measures in time.

[0060] The Type-C interface and magnetic charging interface provide users with convenient charging and data transmission methods. The Type-C interface is reversible, which simplifies the charging process; while the magnetic charging interface uses magnetic connection to make the charging process more stable and reliable. At the same time, these two interfaces also support data transmission, which is convenient for users to set parameters or export data for the device.

[0061] The EMC protection and fuse settings provide safe electromagnetic compatibility and overcurrent protection for the device. These designs ensure the stable operation of the device in a complex electromagnetic environment and prevent safety hazards such as circuit damage or fire caused by excessive current.

[0062] The control buttons include a power switch button, a start button, and a reset button. The settings of these buttons allow users to control the start, stop, and reset functions of the device through simple operations. This intuitive and easy-to-use operation interface reduces the difficulty of operation and improves work efficiency.

[0063] The device for automatically releasing the positioning block in the closed space of the aircraft lock ring station in the above embodiment has the following advantages and technical effects:

[0064] 1. By integrating the linear drive mechanism, the leveling release mechanism and the control assembly, the device can automatically complete the release process of the positioning block without manual intervention, thereby improving work efficiency and automation level.

In particular, the setting of the first spring 6 not only helps the smooth movement of the leveling sleeve 4, but also absorbs and buffers external shocks and vibrations to a certain extent, thereby improving the durability and service life of the device.

[0066] 3. The bottom surface of the leveling sleeve 4 is designed to be flat, which ensures stability and accuracy when contacting with the aircraft lock ring station. When the positioning block needs to be released, the leveling sleeve 4 can provide a stable reference surface to ensure that the positioning block can be accurately placed in the predetermined position. The upper and lower ends of the first spring 6 are respectively connected to the first step of the leveling sleeve 4 and the second step of the push rod 5. This arrangement not only ensures the stability of the spring during compression and release, but also effectively absorbs and buffers the impact force generated when the push rod 5 moves, thereby extending the service life of the device.
