Description

Technical Field

[0001] This utility model belongs to the field of drone chassis technology, specifically relating to a pressure rod structure and a drone chassis using the same. Background Technology

[0002] Traditional drone cabin support systems use mechanical hinge connections, which have inherent drawbacks due to their metal bearing structure: the hinge can only achieve single-degree-of-freedom rotation, making it prone to jamming when the support rod is subjected to non-planar external forces; simultaneously, metal components are easily worn and deformed in vibration environments, leading to rotational failure. Especially when frequently opening and closing the cabin, the support rod needs to be adjusted at multiple angles, and the mechanical hinge cannot adapt to changes in spatial posture, forcing the operator to repeatedly correct the support rod angle, significantly reducing deployment efficiency. Furthermore, stress concentration at the connection between the rigid hinge and the support rod makes it prone to fatigue fracture after long-term use. Utility Model Content

[0003] In view of this, the present invention provides a pressure bar structure and a drone housing using the same, the pressure bar structure being able to achieve multi-directional free rotation and having the advantage of fatigue resistance.

[0004] To address the aforementioned problems, according to one aspect of this application, an embodiment of the present invention provides a pressure rod structure for fixing an object to be secured within a box. The pressure rod structure includes a pressure rod body and a rotating shaft assembly. The pressure rod body is rotatably connected to the box via the rotating shaft assembly. The rotating shaft assembly includes a rotating shaft seat, a polymer fiber rope, and a rotating shaft hub. One end of the pressure rod body is connected to one end of the polymer fiber rope via the rotating shaft hub, and the other end of the polymer fiber rope is connected to the rotating shaft seat. The rotating shaft seat is fixed within the box. The pressure rod body can rotate via the rotating shaft assembly to press or release the object to be secured.

[0005] In some embodiments, the polymer fiber rope is made of polymer polyethylene fiber or Kevlar fiber.

[0006] In some embodiments, the pressure bar body is a composite material circular tube, and the composite material is selected from glass fiber or carbon fiber.

[0007] In some embodiments, the pivot seat is fixed inside the housing by adhesive bonding or pre-embedding.

[0008] In some embodiments, the connection end between the rotating shaft and the sub-seat and the polymer fiber rope is fixed by pre-embedding.

[0009] In some embodiments, the pressure bar structure further includes a fixing component disposed within the housing. The fixing component has a first state of pressing the pressure bar body and a second state of releasing the pressure bar body. The objects to be fixed are arranged in rows to form multiple rows of object units to be fixed, each row of object units to be fixed corresponds to one pressure bar body, and one pressure bar body corresponds to one fixing component.

[0010] In some embodiments, the fixing component includes a base disposed between adjacent objects to be fixed, the base being fixed to the housing by pre-embedding; one of the bases has a padlock, and the other bases have pressure bar limiting grooves.

[0011] In some embodiments, the padlock is an arc-shaped component disposed on the top of the base. The arc-shaped component has a constricted opening, and its arc-shaped inner diameter matches the outer diameter of the pressure rod body, so that the pressure rod body can be fixed inside the arc-shaped component or moved outside the arc-shaped component through the constricted opening.

[0012] In some embodiments, when the pressure rod body releases the object to be fixed through the pivot assembly, the pressure rod body can be flipped to the side of the housing and arranged side by side through the pivot assembly, thus avoiding the movement path of the object to be fixed.

[0013] According to another aspect of this application, an embodiment of the present invention provides a drone housing, the drone housing including the above-described pressure bar structure, wherein the object to be fixed is a drone.

[0014] Compared with the prior art, the pressure bar structure of this utility model has at least the following beneficial effects:

[0015] The pressure rod structure provided by this utility model is used to fix an object to be fixed in a box. The pressure rod structure includes a pressure rod body and a rotating shaft assembly. The pressure rod body is rotatably connected to the box through the rotating shaft assembly. The rotating shaft assembly includes a rotating shaft seat, a polymer fiber rope, and a rotating shaft hub seat. One end of the pressure rod body is connected to one end of the polymer fiber rope through the rotating shaft hub seat, and the other end of the polymer fiber rope is connected to the rotating shaft seat. The rotating shaft seat is fixed in the box. The pressure rod body can rotate through the rotating shaft assembly to press or release the object to be fixed.

[0016] This invention replaces rigid bearings with polymer fiber ropes, providing multi-degree-of-freedom rotation and avoiding jamming caused by single-plane limitation. Simultaneously, the flexible design of the polymer fiber ropes enhances durability in vibration environments, solving the problem of wear-induced failure.

[0033] Example 1

[0034] This embodiment provides a compression bar structure, such as Figures 1-8As shown, the pressure rod structure is used to fix the object 1 to be fixed inside the box 2. The pressure rod structure includes a pressure rod body 3 and a rotating shaft assembly 4. The pressure rod body 3 is rotatably connected to the box 2 through the rotating shaft assembly 4. The rotating shaft assembly 4 includes a rotating shaft seat 41, a polymer fiber rope 42, and a rotating shaft hub seat 43. One end of the pressure rod body 3 is connected to one end of the polymer fiber rope 42 through the rotating shaft hub seat 43, and the other end of the polymer fiber rope 42 is connected to the rotating shaft seat 41. The rotating shaft seat 41 is fixed inside the box 2. The pressure rod body 3 can rotate through the rotating shaft assembly 4 to press the object 1 to be fixed or release the object 1 to be fixed.

[0035] The housing 2 serves as the basic structure for accommodating the object to be fixed 1. The pivot seat 41 is integrated into the housing 2 through a fixing method such as bonding or pre-embedding, becoming a stable base for the entire assembly. One end of the polymer fiber rope 42 is connected to the pivot seat 41, and the other end is connected to the pivot hub 43. The end of the pressure rod body 3 is directly connected to the pivot hub 43, ensuring that the pressure rod body 3 can rotate through the pivot assembly 4. The object to be fixed 1 is placed inside the housing 2, specifically below the pressure rod body 3, so that it can be constrained when pressed. In terms of position, the pivot seat 41 is fixed to the side of the housing 2, and the polymer fiber rope 42 hangs between the pivot seat 41 and the pivot hub 43 as a flexible connector, allowing the pivot hub 43 to move freely in space. The pressure rod body 3 extends horizontally, covering the object to be fixed 1 when not in operation, and can adjust its angle to release space when rotating.

[0036] Specifically, the object to be fixed 1, as the object to be fixed, needs to be prevented from moving or falling due to external forces during transportation or storage; the box 2 provides an overall housing platform, protects the object to be fixed 1, and integrates other structures; the main function of the pressure rod body 3 is to apply constraint force to the object to be fixed 1 to prevent it from shifting within the box 2; the function of the rotating shaft assembly 4 is to realize the multi-dimensional rotation of the pressure rod body 3, improving operational flexibility and adaptability; the rotating shaft seat 41 serves as the fixed end of the rotating shaft assembly 4, ensuring that the entire rotating structure is stably anchored on the box 2; the polymer fiber rope 42, with its flexible material, performs a universal connection function, allowing the pressure rod body 3 to rotate freely in any direction; the rotating shaft hub seat 43 connects the polymer fiber rope 42 and the pressure rod body 3, playing a role in transmitting motion and positioning.

[0037] In the overall workflow, when it is necessary to constrain the object to be fixed 1, the pressure rod body 3 rotates to the top position of the housing 2 via the rotating shaft assembly 4, covering the object to be fixed 1 and achieving clamping. At this time, the pressure rod body 3 can be fixed by an external locking mechanism, restricting its degree of freedom. When it is necessary to release the object to be fixed 1, the operator applies external force, such as prying the pressure rod body 3 to the left, so that the polymer fiber rope 42 rotates freely around the sub-base 43 with the rotating shaft, releasing the locked state; furthermore, the pressure rod body 3 moves along the housing 2, away from the position of the object to be fixed 1, ensuring that it does not affect the takeoff path of the UAV. The flexibility of the polymer fiber rope 42 in the rotating shaft assembly 4 allows the pressure rod body 3 to be adjusted at multiple angles, avoiding interference with other structures.

[0038] This embodiment replaces rigid bearings with polymer fiber ropes 42, providing multi-degree-of-freedom rotation and avoiding jamming caused by single-plane limitation. Simultaneously, the flexible design of the polymer fiber ropes 42 enhances durability in vibration environments, solving the problem of wear-induced failure. The pressure rod body 3 is made of composite material to reinforce rigidity, ensuring it is not easily deformed during long-term use. More specifically, the simple structure of the rotating shaft assembly 4 reduces potential failure points, allowing the pressure rod body 3 to rotate quickly during operation without the need for repeated angle corrections; combined with fewer locking points, efficiency is significantly improved. These features comprehensively solve the defects of traditional pressure rods, such as jamming, deformation, and cumbersome operation.

[0039] In a specific embodiment, the polymer fiber rope 42 is made of polymer polyethylene fiber or Kevlar fiber.

[0040] The polymer fiber rope 42 is made of high-molecular-weight polyethylene fiber or Kevlar fiber. This material selection plays a crucial role in realizing the function and improving the performance of the pressure bar structure. Specifically, the selection of high-molecular-weight polyethylene fiber or Kevlar fiber gives the polymer fiber rope 42 high specific strength, enabling it to withstand large tensile forces with extremely low self-weight. The polymer fiber rope 42 serves as a flexible connector between the pivot seat 41 and the pivot hub seat 43. Its material properties ensure that no rigid frictional resistance is generated during the rotation of the pressure bar body 3, fundamentally eliminating the jamming phenomenon of traditional metal pivots. More specifically, the molecular chain structure of high-molecular-weight polyethylene fiber has high orientation and low coefficient of friction, while the aromatic polyamide structure of Kevlar fiber has excellent tensile strength and fatigue resistance. Both enable the polymer fiber rope 42 to maintain stable physical properties under frequent rotation conditions. This design allows the pressure bar body 3 to swing flexibly around the polymer fiber rope 42 in multiple dimensions, while the material's good chemical corrosion resistance can cope with temperature and humidity changes in the unmanned aerial vehicle (UAV) housing operating environment. Furthermore, the durability of the polymer fiber rope 42 directly extends the service life of the entire shaft assembly 4, avoiding the rotational failure problem caused by long-term vibration or deformation of traditional metal bearings. Therefore, the polymer fiber rope 42 made of high-molecular polyethylene fiber or Kevlar fiber fundamentally solves the technical defects of mechanical shafts described in the background art, such as limited single degree of freedom and easy jamming and wear failure.

[0041] In a specific embodiment, the pressure bar body 3 is a composite material circular tube, and the composite material is selected from glass fiber or carbon fiber.

[0042] This embodiment defines the pressure bar body 3 as a composite material cylindrical tube made of glass fiber or carbon fiber. This structural feature solves the core defect of traditional thin aluminum pressure bars being prone to deformation and failure. The pressure bar body 3 adopts a composite material cylindrical tube shape. Its cylindrical structure forms high bending stiffness through a continuous closed section, significantly improving the pressure bar body 3's resistance to deformation under transportation vibration or accidental impact. The properties of glass fiber or carbon fiber composite materials further enhance this advantage. More specifically, the polymer matrix of glass fiber composite materials endows it with excellent impact toughness, and it will not permanently bend even when subjected to large external forces; carbon fiber composite materials achieve a balance between lightweight and high strength through high-modulus fiber layers, ensuring that the pressure bar body 3 remains straight after multiple opening and closing. This design directly solves the problem of torsional deformation caused by insufficient rigidity in traditional thin aluminum rods, avoiding a chain of failures such as misalignment of the pressure bar locking and jamming of the pivot after deformation. Furthermore, the composite material tube and the polymer fiber rope 42 work synergistically: the complex torque borne by the pressure bar body 3 during rotation is evenly distributed by the cross-section of the tube, avoiding stress concentration that could lead to fatigue fracture. Simultaneously, the lightweight nature of the tube and the flexibility of the polymer fiber rope 42 complement each other, allowing the operator to adjust the angle of the pressure bar body 3 with less effort. Therefore, the pressure bar body 3, constructed from a glass fiber or carbon fiber composite material tube, enhances overall reliability from both material properties and geometric structure perspectives while ensuring lightweight design, completely eliminating the risk of constraint failure caused by insufficient rigidity of the pressure bar.

[0043] In a specific embodiment, the rotating shaft seat 41 is fixed inside the housing 2 by bonding or pre-embedding.

[0044] The pivot seat 41 is fixed inside the housing 2 by bonding or pre-embedding. This fixing process design significantly optimizes the overall performance of the pressure rod system in terms of structural integration and reliability. Specifically, the bonding process uses a high-strength adhesive to form a molecular-level bond between the pivot seat 41 and the lightweight foam material of the housing 2, while the pre-embedding method allows the pivot seat 41 to be embedded into the internal structure of the housing 2 during the molding stage. Both methods ensure a gapless and permanent connection between the pivot seat 41 and the housing 2. This design directly eliminates the additional holes and fasteners required for traditional bolt connections, avoiding the risk of mechanical loosening due to vibration. More specifically, when the polymer fiber rope 42 is pulled or the pressure rod body 3 rotates, the load borne by the pivot seat 41 can be evenly transferred to the base material of the housing 2, preventing structural cracking caused by local stress concentration. Furthermore, the integrated fixing method makes the overall structure of the pivot assembly 4 simpler and more compact, reducing interface delamination failure caused by the difference in thermal expansion coefficients between metal parts and foam material, and extending the service life of the housing 2 under varying temperature and humidity environments. Therefore, the hinge seat 41, which is fixed by bonding or pre-embedding, fundamentally solves the technical problems of complex rigid hinge installation structure and easy loosening and wear due to vibration in the traditional method.

[0045] In a specific embodiment, the connection end between the rotating shaft hub 43 and the polymer fiber rope 42 is pre-embedded and fixed.

[0046] The connection between the rotating shaft hub 43 and the polymer fiber rope 42 is pre-embedded, which significantly enhances the durability and reliability of the rotating shaft assembly 4. Specifically, the pre-embedded fixing process directly wraps the end of the polymer fiber rope 42 inside the matrix material of the rotating shaft hub 43, forming a seamless mechanical anchoring structure. Compared with external binding or adhesive methods, its bonding force comes from the microscopic mechanical interlock between the fiber bundle of the polymer fiber rope 42 and the cured material of the rotating shaft hub 43. This design ensures that when the pressure rod body 3 repeatedly rotates and pulls the polymer fiber rope 42, the load is evenly transmitted to the entire fiber rope through the rotating shaft hub 43, effectively eliminating the risk of interlayer delamination caused by local stress concentration. More specifically, the connection between the pre-embedded and cured rotating shaft hub 43 and the polymer fiber rope 42 has anti-repeated bending characteristics, and even under high-frequency oscillation conditions, the polyethylene or Kevlar fiber surface will not break due to friction and wear. This embodiment eliminates the potential for cutting damage to the polymer fiber rope 42 caused by traditional metal clamps, thereby increasing the upper limit of material fatigue life. Therefore, the pre-embedded fixing process of the rotating shaft around the sub-base 43 fundamentally avoids the defects of easy deformation and jamming at the rotating shaft in traditional technologies, ensuring that the pressure rod body 3 maintains flexible rotation capability over a long period.

[0047] In a specific embodiment, such as Figure 1As shown, the pressure rod structure also includes a fixing component 5, which is disposed inside the housing 2. The fixing component 5 has a first state of pressing the pressure rod body 3 and a second state of releasing the pressure rod body 3. The objects to be fixed 1 are arranged in rows to form multiple rows of objects to be fixed units. Each row of objects to be fixed corresponds to one pressure rod body 3, and one pressure rod body 3 corresponds to one fixing component 5.

[0048] The fixing component 5 is located inside the housing 2. In its first state, the fixing component 5 applies a vertically downward force directly to the pressure rod body 3 through a mechanical locking structure, forcing the pressure rod body 3 to adhere tightly to the upper surface of the rows of objects to be fixed 1. At this time, the composite material tube of the pressure rod body 3 stably constrains the objects to be fixed 1 within the housing 2 through its own rigidity. In the second state, the operator manually releases the locking mechanism of the fixing component 5, causing the pressure rod body 3 to lose downward pressure. At this time, the pressure rod body 3 is lifted upward and rotated by the flexible traction of the polymer fiber rope 42 of the rotating shaft assembly 4, forming an operating gap sufficient for picking up and placing the objects to be fixed 1. More specifically, the mechanical constraint in the first state completely suppresses the displacement of items caused by transportation vibration, while the rapid release mechanism in the second state avoids the cumbersome operation of traditional bolt disassembly.

[0049] The arrangement of items 1 in rows refers to multiple items 1 arranged in a straight line within the housing 2 to form independent multi-row units, with each row constituting an independent unit for items to be fixed. A pressure rod body 3 of matching length is positioned directly above each unit, and this pressure rod body 3 is connected to the housing 2 via an independent rotating shaft assembly 4. Each pressure rod body 3 is also equipped with a dedicated fixing component 5 that operates in conjunction with it. Furthermore, each row of units, along with its corresponding pressure rod body 3 and fixing component 5, forms a closed control loop. For example, when a row of items needs to be retrieved, only the fixing component 5 of that row is operated to switch to the second state, while the pressure rod bodies 3 of the remaining rows maintain their first state of pressure, achieving physically isolated group management.

[0050] This embodiment achieves refined control of the pressure bar system through a dual-state mechanism and group matching design integrating the fixing component 5. The first state of the fixing component 5 provides independent and stable constraints for each row of objects to be fixed 1, while the second state enables rapid opening of a single row, preventing displacement of untouched items due to overall unlocking. The row-by-row setup and the one-to-one matching mechanism ensure that when operating any row, the pressure bar bodies 3 of the remaining rows maintain clamping force through the fixing component 5, eliminating cascading disturbances in multi-item systems. Furthermore, this design significantly shortens the single-operation process, solving the problem of requiring overall unlocking for the handling of multiple items.

[0051] In a specific embodiment, such as Figure 2As shown, the fixing component 5 includes a base 51 disposed between adjacent objects to be fixed 1, and the base 51 is fixed in the box 2 by pre-embedding; one of the bases 51 has a padlock 52, and the other bases 51 have pressure bar limiting grooves 53.

[0052] The fixing component 5 includes a base 51, which is positioned in the gap between adjacent objects 1 to be fixed, for example, one base 51 is installed between every two objects 1 to be fixed. All bases 51 are embedded into the foamed substrate of the housing 2 through a pre-embedding process, forming a non-removable integrated structure. One base 51 has a padlock 52 integrated on its top, while the other bases 51 have pressure bar limiting grooves 53. More specifically, the padlock 52 is used to mechanically lock the pressure bar body 3 (first state), and the pressure bar limiting groove 53 restricts its lateral displacement by engaging the tube wall of the pressure bar body 3 without the need for lock intervention. This design, while ensuring multi-point constraint, reduces the number of main locking points to only one padlock 52 per row, significantly simplifying the unlocking process. Furthermore, the pre-embedded base 51 eliminates the damage to the structural integrity of the housing 2 caused by traditional bolt fixing holes, preventing the extension of stress cracks.

[0053] Taking a single row containing three objects to be fixed as an example, two bases 51 need to be set in two adjacent gaps. If the system is configured with four rows of objects to be fixed, then each row of pressure bar body 3 corresponds to one fixing component 5, and each fixing component 5 is equipped with only one padlock 52 on one of its bases 51, that is, a total of four padlocks 52. More specifically, this layout directly solves the defect of "too many padlock points on the pressure bar" mentioned in the background art: traditional designs require a lock to be set on each base; while in this embodiment, only one padlock 52 is retained as the main locking point in each row, and the pressure bar limiting groove 53 undertakes the auxiliary positioning function. The operator only needs to unlock a single padlock 52 to release the entire row of pressure bar bodies 3, which significantly reduces the time by 50%.

[0054] Furthermore, the base 51 for the padlock 52 is fixedly located at the end of the pressure rod body 3, away from the pivot assembly 4 (i.e., the far end where the pressure rod has the greatest degree of freedom of swing). More specifically, this arrangement allows the operator to concentrate a single unlocking action on the moving end of the pressure rod body 3, completely avoiding interference with the rotation trajectory of the pivot assembly 4. At the same time, the pressure rod limiting grooves 53 are distributed on the base 51 near the pivot assembly 4, forming a three-point constraint system: the padlock 52 controls the downward pressure at the far end, and the pressure rod limiting grooves 53 maintain the lateral positioning at the near end. This mechanical distribution ensures that the bending moment of the pressure rod body 3 is evenly transmitted to each base 51 when under load, preventing the material of the housing 2 from crushing due to excessive stress at a single point, and ensuring reliability for long-term use.

[0055] In a specific embodiment, such as Figures 4-6As shown, the padlock 52 is an arc-shaped component disposed on the top of the base 51. The arc-shaped component has a constricted opening, and its arc-shaped inner diameter matches the outer diameter of the pressure rod body 3, so that the pressure rod body 3 can be fixed inside the arc-shaped component or moved out of the arc-shaped component through the constricted opening.

[0056] The padlock 52 is specifically a semi-enclosed arc-shaped metal component fixed to the top of the base 51. The inner curvature of this component precisely matches the outer contour of the composite material tube of the pressure rod body 3. Its top end has a constricted opening with a width smaller than the diameter of the pressure rod body 3. When the pressure rod body 3 is pressed down to the first state, its tube elastically deforms and squeezes through the constricted opening into the arc-shaped cavity. At this point, the constricted opening resets, confining the pressure rod body 3 inside the arc-shaped component, preventing it from detaching. When switching to the second state, the operator pulls the pressure rod body 3 laterally, forcing the constricted opening to elastically expand, allowing the pressure rod body 3 to move out of the arc-shaped component. More specifically, this structure achieves a self-locking function through material deformation characteristics, eliminating the need for additional latch operation required by traditional padlocks. The encircling design of the arc-shaped component ensures that the pressure rod body 3 does not move axially under vibration. Furthermore, the interference fit between the constricted opening and the pressure rod body 3 prevents wear on the composite material surface from the metal lock, extending the fatigue life of the pressure rod body 3.

[0057] In a specific embodiment, such as Figure 8 As shown, when the pressure rod body 3 releases the object to be fixed 1 through the rotating shaft assembly 4, the pressure rod body 3 can be flipped to the side of the box 2 and arranged side by side through the rotating shaft assembly 4, thus avoiding the movement path of the object to be fixed 1.

[0058] When the operator releases the padlock 52, the pressure rod body 3, utilizing the rotatable characteristic of the pivot assembly 4, flips outward from the position where it vertically presses against the object to be fixed 1, until the pressure rod body 3 is parallel to and against the side wall of the box 2. At this time, the length direction of the pressure rod body 3 remains parallel to the side of the box 2, and the overall height of the pressure rod body 3 is lowered below the horizontal plane of the top of the object to be fixed 1. More specifically, this flipping trajectory completely avoids the vertical movement path of the object to be fixed 1, ensuring that there is no structural interference when the object is removed. Furthermore, through the rotation limiting mechanism of the pivot assembly 4, the pressure rod body 3 is precisely positioned in the preset storage area on the side wall of the box 2, forming a stable lateral hovering state.

[0059] In this embodiment, the pressure bar body 3 is completely detached from the work area when released, eliminating the risk of parts loss caused by the need to disassemble and store traditional pressure bars; the side-by-side arrangement allows multiple rows of pressure bar bodies 3 to be stored simultaneously, avoiding accidental collision with the released pressure bar body 3 when operating other objects to be fixed 1; more specifically, the obstacle avoidance path design ensures that the object to be fixed 1 can be retrieved and placed without obstruction in the vertical direction, solving the defect in traditional technology that "the pressure bar still occupies space and hinders operation after unlocking".

[0060] The working process of the compression bar structure provided in this embodiment is as follows:

[0061] The objects to be fixed 1 are arranged in a row inside the housing 2. The pressure rod body 3 is connected to the housing 2 via a rotating shaft assembly 4 and provides flexible support. The fixing assembly 5 is installed inside the housing 2 to control the state switching of the pressure rod body 3. In the first state, the fixing assembly 5 activates the locking mechanism: specifically, the pressure rod body 3 is vertically pressed against the upper surface of the object to be fixed 1. At this time, the padlock 52 is fixed to the top of the base 51 and locks the pressure rod body 3 into its arc-shaped cavity. The pressure rod limiting groove 53 engages with the pressure rod body 3 on the other bases 51 to assist in lateral constraint. The polymer fiber rope 42 of the rotating shaft assembly 4 provides initial elasticity to the pressure rod body 3, but the whole is suppressed by the fixing assembly 5, ensuring that the object to be fixed 1 is stably fixed during transportation. In the second state, the operator manually releases the fixing component 5: the operator pulls the pressure rod body 3 to disengage it from the constriction of the padlock 52 and disengage it from the pressure rod limiting groove 53. The pressure rod body 3 then rises upward under the traction of the rotating shaft assembly 4, creating a gap. Furthermore, the pressure rod body 3 can be flipped to the side of the housing 2 via the rotating shaft assembly 4 and arranged side by side, maintaining a parallel state, completely avoiding the vertical movement path of the object to be fixed 1. After the operation is completed, the pressure rod body 3 flips back to its original position via the rotating shaft assembly 4 and is relocked by the padlock 52 and the pressure rod limiting groove 53 of the fixing component 5, entering the first state, realizing the cyclical working process. This mechanism utilizes the mobility of the rotating shaft assembly 4 to optimize the spatial layout, while the grouped design of the fixing component 5 allows single-row operation without interfering with other rows, improving operational efficiency and system reliability.

[0062] Example 2

[0063] This embodiment provides a drone housing, which includes the pressure bar structure described in Embodiment 1, wherein the object to be fixed 1 is a drone.

[0064] This embodiment, by applying the pressure bar structure of Embodiment 1, significantly improves the storage efficiency and reliability of drones in the drone housing: the pressure bar body, with the flexible support of the pivot assembly and the phased locking mechanism of the fixing assembly, achieves stable constraint on the drones, eliminating the risk of loosening during transportation; more specifically, the combination of the single-point control of the padlock of the fixing assembly and the auxiliary positioning of the pressure bar limit groove greatly reduces the unlocking steps, enabling the rapid release of single-row drones; the pivot assembly allows the pressure bar body to be flipped to the side of the housing, completely avoiding the vertical loading and unloading path of drones and preventing scratches; furthermore, the pre-embedded integrated design of the base ensures that the overall structural strength of the housing is protected from crushing failure, meeting the long-term reliability requirements of high-frequency drone storage and retrieval scenarios.

[0065] In summary, it is readily understood by those skilled in the art that, without conflict, the aforementioned advantageous technical features can be freely combined and superimposed.

[0066] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model in any way. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall still fall within the scope of the technical solution of the present utility model.
