Abstract
Description
Technical Field
[0001] This invention relates to the field of auxiliary equipment for pod assembly, debugging or testing, and specifically to a pod-mounted vehicle that can adjust pods in multiple dimensions. Background Technology
[0002] In aerospace, transportation, and industrial manufacturing, specialized support vehicles are indispensable equipment for storing, transporting, and maintaining various pods (such as optoelectronic pods, radar pods, and weapon pods). The core function of such equipment is to provide stable and secure support and fixation for valuable and structurally complex pods, and it must adapt to the different requirements of different pod models in terms of size, shape, and support point locations.
[0003] Currently, most existing pod-mounted vehicles use fixed support structures, which generally suffer from the following problems: 1. Poor adaptability: The width and height of the support frame are usually fixed values, or can only be roughly adjusted within a limited range. When faced with new pods with large differences in size and specifications, existing equipment often cannot achieve precise adaptation, resulting in low versatility. Users need to configure special storage vehicles for different pods, which significantly increases the purchase and storage costs.
[0004] 2. Limited Functionality: Traditional storage vehicles are primarily limited to horizontal storage and short-distance transport, lacking the ability to adjust the attitude of the pods. However, in actual maintenance, inspection, or assembly tasks, it is often necessary to position the pods at a specific pitch angle. Existing technologies typically require additional, complex angle adjustment mechanisms or temporary tooling such as shims to achieve this attitude adjustment, resulting in cumbersome operation, poor stability, and safety hazards. Summary of the Invention
[0005] In order to solve the technical problems existing in the background art, the present invention proposes a pod-mounted vehicle with multi-dimensional adjustable pods.
[0006] The present invention proposes a multi-dimensional adjustable pod mounting vehicle, comprising: a first side support and a second side support, wherein: The first side support and the second side support are connected to each other by a telescopic rod with adjustable axial length. Both the first side support and the second side support include a lower support and an upper support assembly mounted on the lower support. The height of the upper support assembly relative to the lower support is adjustable. The upper support assembly includes an upper support, a transverse telescopic rod, a first stop, a second stop, and a strap. The transverse telescopic rod has a synchronous telescopic function at both ends. The transverse telescopic rod is arranged horizontally along a direction perpendicular to the axis of the telescopic rod and is fixedly connected to the upper support. The first stop and the second stop are symmetrically installed on both sides of the transverse telescopic rod. One end of the strap is connected to the second stop, and the other end is used to fix it to the first stop after passing through or wrapping around the object to be fixed.
[0007] Preferably, the proximal end of the first stop is hinged to the corresponding end of the transverse telescopic rod via a first hinge shaft, and a locking mechanism is provided at its distal end; the proximal end of the second stop is hinged to the same end of the transverse telescopic rod via a second hinge shaft, and its distal end is fixedly connected to one end of the strap; the free end of the strap passes through or wraps around the object to be fixed and is led to the locking mechanism for tensioning and fixing by the locking mechanism.
[0008] Preferably, the locking mechanism includes a base and a locking stop; the inner surface of the strap is provided with one-way ratchet teeth continuously distributed along its length; the locking stop is rotatably mounted on the base via a pivot, and together with the base, defines a guide hole for the strap to pass through; the front end of the locking stop is provided with an engagement part that matches the shape of the one-way ratchet teeth, and when the strap passes through the guide hole in the traction direction, the force of the one-way ratchet teeth on the engagement part drives the locking stop to tend to disengage around the pivot; when the strap exhibits a reverse movement tendency, this tendency will drive the locking stop to rotate, causing its engagement part to engage with the ratchet teeth instantaneously, forming a reverse lock.
[0009] Preferably, the telescopic rod includes a fixed rod and a movable rod, wherein the fixed rod is a hollow rod, and one end of the movable rod is inserted into the fixed rod in a plug-in manner and can move axially; the fixed rod integrates a first drive mechanism, which applies axial thrust or tension to the movable rod through mechanical transmission or linear drive.
[0010] Preferably, the movable rod is a rack and pinion; the first drive mechanism includes a first handwheel mounted on the outside of the fixed rod and a first drive gear mounted on the shaft end of the first handwheel, the first drive gear meshing with the movable rod for transmission.
[0011] Preferably, the lower support is provided with a guide channel extending in the vertical direction; the upper support is a rod vertically set at the lower end of the transverse telescopic rod to support the transverse telescopic rod, and is axially movable and assembled in the guide channel; the lower support is integrated with a second drive mechanism, which applies axial thrust or tension to the upper support through mechanical transmission or linear drive.
[0012] Preferably, the upper support is a rack and pinion; the second drive mechanism includes a second handwheel mounted on the outside of the lower support and a second drive gear mounted on the shaft end of the second handwheel, the second drive gear meshing with the upper support for transmission.
[0013] Preferably, the transverse telescopic rod includes a central positioning rod, a first pull rod, and a second pull rod, wherein the central positioning rod is a hollow rod and is fixedly connected to the top of the upper support; the first pull rod and the second pull rod are symmetrically arranged at both ends of the central positioning rod, and one end of each is nested inside the central positioning rod in an insert manner.
[0014] Preferably, both the bottom of the first side support and the second side support are provided with rollers.
[0015] In this invention, the first and second side support seats are connected in opposite directions by an axially adjustable telescopic rod. The center distance between the first and second side support seats is adjusted and locked via the telescopic rod, thus forming a stable rigid support frame. The first and second side support seats are vertically adjustable through a height-adjustable upper support assembly that works in conjunction with the lower support. Simultaneously, the lateral telescopic rod in the upper support assembly drives the end stops to extend and retract synchronously, allowing for flexible adjustment of the strap anchoring width. This structural design integrates three-dimensional adjustment functions—longitudinal, vertical, and lateral—to form an adaptive rigid support frame. This allows it to precisely adapt to the diverse placement needs of pods of different sizes, exhibiting excellent versatility. Furthermore, by adjusting the height difference between the two upper support assemblies, the pod can be actively positioned at the required pitch angle. This breakthrough extends the single storage function to include attitude adjustment capabilities, enriching the functional attributes of the placement vehicle and broadening its application range.

Detailed Implementation
[0017] Reference Figure 1-2 The present invention proposes a multi-dimensional adjustable pod mounting vehicle, comprising: a first side support 1 and a second side support 2, wherein: The first side support 1 and the second side support 2 are connected to each other by a telescopic rod 3 with adjustable axial length. The center distance between the first side support 1 and the second side support 2 can be adjusted and locked by adjusting the length of the telescopic rod 3, thereby forming a stable rigid support frame. In order to facilitate the adjustment of the center distance between the first side support 1 and the second side support 2, rollers are provided at the bottom of both the first side support 1 and the second side support 2.
[0018] Specifically, the telescopic rod 3 includes a fixed rod 31 and a movable rod 32. The fixed rod 31 is a hollow rod, and one end of the movable rod 32 is inserted into the fixed rod 31, allowing for axial extension and retraction. A first drive mechanism is integrated on the fixed rod 31, which applies axial thrust or tension to the movable rod 32 via mechanical transmission or linear drive. During adjustment, the fixed rod 31 serves as a static reference and main load-bearing component, while the movable rod 32 extends and retracts axially under its internal guidance, directly changing the total length of the telescopic rod 3. The first drive mechanism integrated on the fixed rod 31 acts as a power source, converting rotational or linear motion into axial thrust or tension on the movable rod 32 via mechanical transmission methods such as worm gears and racks or linear drive methods such as electric push rods, driving its stable extension or retraction. This structural design enables stepless and precise adjustment of the support frame span, ultimately allowing the vehicle to quickly adapt to the longitudinal support requirements of pods of different specifications. Furthermore, this structure can synchronously control the relative or opposite movements of the first side support 1 and the second support through a single-point drive, maintaining the symmetry of the frame throughout the adjustment process, and achieving rigid locking at any telescopic position through self-locking characteristics or the locking capability of the drive element itself.
[0019] Furthermore, the movable lever 32 is a rack and pinion; the first drive mechanism includes a first handwheel 5 mounted outside the fixed lever 31 and a first drive gear mounted on the shaft end of the first handwheel 5, which meshes with the movable lever 32 for transmission. This transmission structure achieves precise linear drive through the gear-rack meshing principle: when the operator rotates the first handwheel 5, the first drive gear at its shaft end rotates synchronously, and through meshing with the rack and pinion lever as the movable lever 32, the rotational motion of the handwheel is efficiently and directly converted into the linear extension and retraction motion of the movable lever 32 relative to the fixed lever 31. This structural design, on the one hand, has reliable self-locking characteristics, can reliably lock in any position, and ensures the rigid fixation and load-bearing stability of the movable lever 32 in either extended or retracted state; on the other hand, it has a compact structure, high mechanical efficiency, and achieves convenient human-machine operation through the external first handwheel 5.
[0020] Both the first side support 1 and the second side support 2 include a lower support 01 and an upper support assembly 02 mounted on the lower support 01. The height of the upper support assembly 02 relative to the lower support 01 is adjustable so that the height of the support surface can be adjusted by adjusting the height of the upper support assembly 02.
[0021] Specifically, the upper support assembly 02 includes an upper support 021, a transverse telescopic rod 022, a first stop 023, a second stop 024, and a strap 025. Rollers are located at the bottom of the lower support 01, which has a guide channel extending vertically. The upper support 021 is a vertically mounted member at the lower end of the transverse telescopic rod 022 to support it, and is axially movable within the guide channel. A second drive mechanism is integrated on the lower support 01. This second drive mechanism applies axial thrust or tension to the upper support 021 via mechanical transmission or linear drive, driving the upper support 021 to move axially along the vertical guide channel of the lower support 01, thereby achieving the overall lifting and lowering of the upper support 021 and the transverse telescopic rod 022, the first stop 023, the second stop 024, and the strap 025 it supports.
[0022] Furthermore, the upper support 021 is a rack and pinion mechanism; the second drive mechanism includes a second handwheel 6 mounted on the outside of the lower support 01 and a second drive gear mounted on the shaft end of the second handwheel 6, which meshes with the upper support 021 for transmission. During adjustment, rotating the second handwheel 6 drives the second drive gear to rotate, and the meshing transmission between the second drive gear and the upper support 021 causes the upper support 021 to move vertically up and down relative to the lower support 01. This structural design achieves stepless and precise adjustment of the support surface height, and thanks to the reliable self-locking characteristics of the rack and pinion mechanism, it ensures the stable maintenance of the support height under load conditions.
[0023] The lateral telescopic rod 022 has a synchronous telescopic function at both ends. It is horizontally arranged along a direction perpendicular to the axis of the telescopic tie rod 3 and fixedly connected to the top of the rod, with its fixing point located in the middle of the rod body, for adjusting the lateral span. The first stop rod 023 and the second stop rod 024 are symmetrically installed on both sides of the lateral telescopic rod 022 to serve as anchoring points for the binding strap 025. One end of the binding strap 025 is connected to the second stop rod 024, and the other end passes through or wraps around the object to be fixed before being fixed to the first stop rod 023 on the other side.
[0024] Specifically, the transverse telescopic rod 022 includes a central positioning rod, a first pull rod, and a second pull rod. The central positioning rod is hollow and fixedly connected to the top of the upper support 021, with its fixing point located in the middle of the central positioning rod. The first and second pull rods are symmetrically arranged at both ends of the central positioning rod, with one end of each rod nested inside the central positioning rod in an insert manner. The transverse telescopic rod 022 achieves stepless adjustment of its overall transverse width through the synchronous pulling motion of the first and second pull rods, which can move in opposite directions. Its power transmission relies on the push-pull force applied directly by the operator to the pull rods, or is driven by a linkage mechanism built into the central positioning rod, such as a synchronous gear and rack system, ensuring the synchronicity and stability of the extension and retraction on both sides. This structure, with the central positioning rod as a fixed base and motion guide, forms a symmetrical telescopic structure, ensuring that the straps 025 connected to both ends of the transverse telescopic rod 022 can accurately and reliably adapt to the fixing needs of objects of different sizes.
[0025] In a further embodiment, the proximal end of the first stop bar 023 is hinged to the corresponding end of the transverse telescopic rod 022 via a first hinge shaft, and a locking mechanism 4 is provided at its distal end; the proximal end of the second stop bar 024 is hinged to the same end of the transverse telescopic rod 022 via a second hinge shaft, and its distal end is fixedly connected to one end of the strap 025; the free end of the strap 025 passes through or wraps around the object to be fixed and is led to the locking mechanism 4 for tensioning and fixing by the locking mechanism 4. By hinged the first stop bar 023 and the second stop bar 024 to the end of the transverse telescopic rod 022, and combined with the locking mechanism 4 and the fixing point of the strap 025 at the distal end, rapid tensioning and reliable locking of the strap 025 after it wraps around the object are achieved. This not only allows the anchoring width of the strap 025 to be adjusted synchronously with the lateral telescopic rod 022, but also endows the first stop rod 023 and the second stop rod 024 with adaptive deflection capability through the hinge structure, so that they can adapt to different extension angles of the strap 025, effectively avoiding bending, twisting and stress concentration, thereby eliminating the twisting and wear of the strap 025 during the telescopic adjustment process. In this way, while ensuring rigid locking, it can improve the wrapping performance, fixing reliability, operation convenience and service life of the strap 025 for objects of different sizes and shapes.
[0026] Specifically, the locking mechanism 4 includes a base and a locking stop; the inner surface of the strap 025 is provided with one-way ratchet teeth continuously distributed along its length; the locking stop is rotatably mounted on the base via a pivot, and together with the base, defines a guide hole for the strap 025 to pass through; the front end of the locking stop is provided with an engagement part matching the shape of the one-way ratchet teeth, and when the strap 025 passes through the guide hole in the traction direction, the force of the one-way ratchet teeth on the engagement part drives the locking stop to tend to disengage around the pivot; when the strap 025 exhibits a reverse movement tendency, this tendency will drive the locking stop. The locking mechanism rotates, causing its engaging part to instantly engage with the ratchet, forming a reverse lock. Specifically, this locking lever has two working states: when the strap 025 moves in the first direction (i.e., the traction direction), the engaging part of the locking lever tends to disengage from the one-way ratchet, allowing the strap 025 to pass freely and achieve continuous adjustment; when the strap 025 is subjected to external force and tends to move in a second direction opposite to the first direction, the locking lever will be driven to rotate around its pivot, causing its engaging part to quickly engage with the one-way ratchet, generating a self-locking effect, thereby preventing the strap 025 from moving in the opposite direction and achieving reliable locking. This locking mechanism 4, through the one-way engagement principle of the ratchet and the locking lever, achieves stepless, continuous adjustment of the strap 025 in the traction direction and instantaneous self-locking in the reverse direction. It is extremely simple to operate and responds quickly, while effectively preventing accidental loosening due to operational negligence or external impact, providing the pod and other secured objects with impact resistance and anti-reverse slippage capabilities exceeding those of conventional strap 025 mechanisms.
[0027] As can be seen from the above, in this invention, the first side support 1 and the second side support 2 are connected in opposite directions by a telescopic rod 3 with adjustable axial length. The center distance between the first side support 1 and the second side support is adjusted and locked by the telescopic rod 3, thereby forming a stable rigid support frame. The first side support 1 and the second side support 2 are vertically adjusted by the cooperation of the height-adjustable upper support component 02 and the lower support 01. At the same time, the transverse telescopic rod 022 in the upper support component 02 can drive the end stops to extend and retract synchronously, so as to flexibly adjust the anchoring width of the strap 025. This structural design integrates three-dimensional adjustment functions in the longitudinal, vertical and transverse directions, which together form an adaptive rigid support frame, enabling it to accurately adapt to the diverse placement needs of pods of different sizes, and has good versatility. At the same time, by adjusting the height difference between the two upper support components 02, the pod can be actively made to form the required pitch angle. This function breaks through the single storage function to have the ability to adjust the posture, enriches the functional attributes of the placement vehicle, and broadens its application range.
[0028] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
