Description

Technical Field

[0001] This utility model belongs to the technical field of lifting devices, and relates to a portable ground station folding screen lifting mechanism. Background Technology

[0002] During takeoff, landing, and flight, aircraft are typically controlled and monitored via ground-based control terminals, or ground stations. Existing ground stations separate power, signaling, and control equipment, resulting in low integration and inconvenience for transportation, use, and storage. Furthermore, existing ground stations suffer from cumbersome cabling, large size, and weight, and the separate storage of the control terminal and related equipment makes them inconvenient to use. To facilitate operation, the folding screen and operating components of the ground station are usually mounted on a height-adjustable platform to accommodate different operator height requirements. To ensure the stability of the platform, a locking mechanism is needed. Current technology typically uses locking pins on the platform for locking. However, these pins only provide single-point locking, offering insufficient support. Moreover, the pins require manual insertion and removal after aligning with the locking holes, which is inconvenient.

[0003] Therefore, in view of the problems of insufficient locking stability and cumbersome locking operation of the existing ground station operation terminal lifting platform, this utility model discloses a portable ground station folding screen lifting mechanism. Utility Model Content

[0004] The purpose of this utility model is to provide a portable ground station folding screen lifting mechanism, which can drive the ground station operating terminal to lift smoothly, and can lock the lifting frame securely in any locking position. When the lifting frame is lowered to the lowest position, it can be completely stored inside the ground station housing, making it more portable.

[0005] This utility model is achieved through the following technical solution:

[0006] A portable ground station folding screen lifting mechanism includes a ground station housing and a lifting frame vertically slidably mounted on the inner wall of the ground station housing. The lifting frame has a first locking mechanism and a second locking mechanism detachably connected to the ground station housing at both ends. The first locking mechanism includes at least one first locking part that engages with or disengages from the housing wall of the ground station housing as the lifting frame moves. The second locking mechanism includes at least one second locking part that engages with or disengages from the housing wall of the ground station housing as the lifting frame moves.

[0007] The lifting frame and the ground station housing have several locking positions corresponding to different lifting heights. When the lifting frame is raised to any locking position, the first locking part of the first locking mechanism and the second locking part of the second locking mechanism engage and lock with the corresponding wall of the ground station housing to fix the lifting frame at the corresponding height. When it is necessary to adjust the height of the lifting frame or lower the lifting frame for storage, the unlocking parts of the first and second locking parts are disengaged from the ground station housing, and the lifting frame can continue to be raised and lowered. When the lifting frame is lowered to its lowest limit position, the lifting frame and the ground station folding screen located on top of the lifting frame are completely lowered and stored inside the ground station housing. At this time, the first and second locking mechanisms are also completely stored inside the ground station housing, facilitating the portable movement of the entire ground station housing and its internal components.

[0008] To better realize this utility model, the first locking mechanism further includes a pull rod, a return spring, and a first locking cylinder. The first locking cylinder is disposed at one end of the bottom of the lifting frame. The pull rod is slidably disposed inside the first locking cylinder. The return spring is sleeved on the outside of the pull rod. One end of the return spring abuts against the inside of the first locking cylinder. One end of the pull rod is correspondingly disposed with a locking hole on the wall of the ground station box.

[0009] To better realize this utility model, the first locking mechanism further includes a first locking plate, which is vertically disposed on the wall of the ground station box, and the first locking plate is provided with a plurality of locking holes in the vertical direction.

[0010] To better realize this utility model, the first locking mechanism further includes a guide cylinder, which is disposed at the bottom of the lifting frame away from the first locking cylinder, and the pull rod is slidably connected to the guide cylinder.

[0011] To better realize this utility model, the second locking mechanism further includes a locking arm and a locking button. The first end of the locking arm is rotatably hinged to the wall of the ground station box, and the second end of the locking arm is slidably connected to one side of the lifting frame. The locking button is located at the bottom of the lifting frame. When the locking button is pressed, it can disengage from the locking hole on the second end of the locking arm to unlock.

[0012] The aforementioned locking button directly adopts existing commercially available products, and the structure of the locking button itself is not an improvement point of this application. Therefore, the specific structure and usage principle of the locking button will not be described in detail here.

[0013] To better realize this utility model, a horizontal slide groove is further provided on one side of the lifting frame, and a slider is hinged to the second end of the locking swing arm. The slider is slidably connected to the horizontal slide groove. A number of locking holes are provided on the side of the horizontal slide groove away from the slider in the horizontal direction, and a locking button is provided for each locking hole.

[0014] To better realize this utility model, a lifting slider is further provided on the side of the lifting frame near the box wall of the ground station box, and a vertical sliding groove is provided on the box wall of the ground station box, and the lifting slider is slidably connected with the vertical sliding groove.

[0015] To better realize this utility model, a lifting device is further provided at the bottom of the lifting frame, located between the first locking mechanism and the second locking mechanism.

[0016] To better realize this utility model, the lifting device further includes any one of a hydraulic push rod, a pneumatic push rod, and an electric push rod.

[0017] Compared with the prior art, this utility model has the following advantages and beneficial effects:

[0018] (1) By setting a first locking mechanism and a second locking mechanism at both ends of the bottom of the lifting frame, the lifting frame can be double-locked by the first locking mechanism and the second locking mechanism after the lifting frame is raised to a specified height, thereby ensuring the stability of the lifting frame and the operating terminal on the lifting frame.

[0019] (2) Both the first locking mechanism and the second locking mechanism are designed to automatically lock and fold and store along with the lifting frame, avoiding tedious manual operation, making the movement, locking and unlocking of the lifting frame more convenient, and can be stored in the box at the same time when the ground station operation terminal is stored, making it more portable and easy to use.

[0031] Example 1:

[0032] This embodiment provides a portable ground station folding screen lifting mechanism, such as... Figure 1As shown, the device includes a ground station housing and a lifting frame 5 that is vertically slidably mounted on the inner wall of the ground station housing. The lifting frame 5 has a first locking mechanism 6 and a second locking mechanism 7 that are detachably connected to the ground station housing at both ends. The first locking mechanism 6 includes at least one first locking part that engages with or disengages from the housing wall of the ground station housing as the lifting frame 5 moves. The second locking mechanism 7 includes at least one second locking part that engages with or disengages from the housing wall of the ground station housing as the lifting frame 5 moves.

[0033] The lifting frame 5 is slidably connected to the wall of the ground station housing along the vertical direction. When the lifting frame 5 is subjected to a vertical external force, it can be raised and lowered relative to the ground station housing. The top of the lifting frame 5 is equipped with components such as the ground station folding screen and operating handle. A first locking mechanism 6 and a second locking mechanism 7 are respectively provided at both ends of the bottom of the lifting frame 5. The lifting frame 5 is locked by the engagement of the first locking mechanism 6 and the second locking mechanism 7 with the wall of the ground station housing, ensuring that the lifting frame 5 can be stably stopped at the set height.

[0034] Several locking positions are set vertically along the wall of the ground station housing to correspond to different lifting heights. Whenever the lifting frame 5 is raised to any locking position, the first locking mechanism 6 and the second locking mechanism 7 engage with the ground station housing to lock the height of the lifting frame 5. When it is necessary to continue sliding the lifting frame 5, the first locking part and the second locking part are unlocked from the ground station housing, and the lifting frame 5 can continue to slide.

[0035] Furthermore, when the lifting frame 5 descends to its lowest limit position, the first locking mechanism 6 and the second locking mechanism 7 are simultaneously retracted into the interior of the ground station housing along with the lifting frame 5.

[0036] Example 2:

[0037] A portable ground station folding screen lifting mechanism, improved based on Embodiment 1, such as... Figure 2-Figure 4 As shown, the first locking mechanism 6 includes a pull rod 61, a return spring 62, and a first locking cylinder 63. The first locking cylinder 63 is disposed at one end of the bottom of the lifting frame 5. The pull rod 61 is slidably disposed inside the first locking cylinder 63. The return spring 62 is sleeved on the outside of the pull rod 61. One end of the return spring 62 abuts against the inside of the first locking cylinder 63. One end of the pull rod 61 is correspondingly disposed with a locking hole on the wall of the ground station box.

[0038] The ground station enclosure has several locking holes along its vertical direction corresponding to different lifting heights. When the lifting frame 5 slides to the corresponding locking position, the return spring 62 drives the pull rod 61 to slide towards the locking hole, so that the end of the pull rod 61 engages with the locking hole, thus fixing the lifting frame 5 at the current height. To continue sliding the lifting frame 5, pull the pull rod 61 away from the locking hole, disengaging the end of the pull rod 61 from the locking hole. Simultaneously, the second locking mechanism 7 is unlocked, allowing the lifting frame 5 to continue sliding.

[0039] Furthermore, the first locking mechanism 6 includes a first locking plate 64, which is vertically mounted on the wall of the ground station housing. The first locking plate 64 has several locking holes arranged vertically on it. When the pull rod 61 moves with the lifting frame 5 to any locking position, the axial force provided by the return spring 62 causes the end of the pull rod 61 to extend into the locking hole and engage with it, thus fixing the lifting frame 5.

[0040] Furthermore, the first locking mechanism 6 includes a guide cylinder 65, which is disposed at the bottom of the lifting frame 5 away from the first locking cylinder 63. The pull rod 61 is slidably connected to the guide cylinder 65. The inner hole of the guide cylinder 65 is slidably engaged with the pull rod 61 and guides the sliding of the pull rod 61, ensuring that the pull rod 61 can smoothly slide to the state corresponding to the locking hole in any locking position.

[0041] The other parts of this embodiment are the same as those in Embodiment 1, so they will not be described again.

[0042] Example 3:

[0043] A portable ground station folding screen lifting mechanism, improved based on embodiment 1 or 2, such as... Figure 2 , Figure 5 , Figure 6 As shown, the second locking mechanism 7 includes a locking arm 71 and a locking button 72. The first end of the locking arm 71 is rotatably hinged to the wall of the ground station box, and the second end of the locking arm 71 is slidably connected to one side of the lifting frame 5. The locking button 72 is located at the bottom of the lifting frame 5. When the locking button 72 is pressed, it can disengage from the locking hole on the second end of the locking arm 71 to unlock.

[0044] The first end of the locking arm 71 is rotatably hinged to the wall of the ground station housing, while the second end of the locking arm 71 is slidably connected to one side of the lifting frame 5 in a horizontal direction. When the lifting frame 5 is raised or lowered, the locking arm 71 rotates accordingly. When the lifting frame 5 is raised or lowered to any locking position, the locking button 72 located at the bottom of the lifting frame 5 engages with the locking hole on the second end of the locking arm 71 to restrict the rotation of the locking arm 71, thereby restricting the raising or lowering of the lifting frame 5. To continue moving the lifting frame 5, press the locking button 72 to disengage it from the locking hole, unlocking the second end of the locking arm 71, allowing the lifting frame 5 to continue sliding up and down. When the lifting frame 5 descends to its lowest limit position, the locking arm 71 rotates to its retracted position completely inside the ground station housing.

[0045] Furthermore, a horizontal slide groove 73 is provided on one side of the lifting frame 5, and a slider 74 is hinged to the second end of the locking arm 71. The slider 74 is slidably connected to the horizontal slide groove 73. A number of locking holes are provided on the side of the horizontal slide groove 73 away from the slider 74 in the horizontal direction, and a locking button 72 is provided for each locking hole.

[0046] One side of the slider 74 is slidably connected to the horizontal slide groove 73, and the other side of the slider 74 is rotatably hinged to the second end of the locking arm 71. A locking hole is also provided on the slider 74. During the vertical lifting and lowering of the lifting frame 5, the slider 74 slides along the horizontal slide groove 73. When the lifting frame 5 reaches any locking position, the slider 74 inside the horizontal slide groove 73 slides to the position where the locking hole aligns with the locking button 72. At this point, the locking button 72 engages with the locking hole on the slider 74, locking the locking arm 71 and thus locking the lifting frame 5.

[0047] The other parts of this embodiment are the same as those in Embodiment 1 or 2, so they will not be described again.

[0050] By connecting the lifting slider 51 with the vertical slide groove, the lifting frame 5 is smoothly guided to move and lift smoothly along the vertical direction.

[0051] The other parts of this embodiment are the same as any one of embodiments 1-3, so they will not be described again.
