Description

Technical Field

[0001] This utility model relates to an amphibious vehicle with a chassis folding bracket. Background Technology

[0002] Amphibious vehicles can travel on land like cars and float on water like boats. They typically have a buoyancy-supporting body design and underwater propellers mounted underneath the body, propelled by electric or fuel-powered engines.

[0003] Conventional amphibious vehicles have iron blocks on both sides of their bottom, allowing them to be lifted using existing lifting structures for maintenance. However, this structure has significant limitations. Amphibious vehicles need to be used on both land and water. While the conventional iron block structure is suitable for land-based maintenance, it is unusable on water, as it cannot connect and secure the amphibious vehicle to the surface floats. Therefore, this invention focuses on designing a chassis folding frame that can serve as both a land-based maintenance auxiliary component and a water-based fixing and connection component. Utility Model Content

[0004] This invention provides an amphibious vehicle with a folding chassis support, which can effectively solve the above problems.

[0005] This utility model is implemented as follows:

[0006] A chassis folding support includes a support body mounted on an amphibious vehicle chassis and a plurality of connecting rods mounted at a first end of the support body.

[0007] A positioning rod is disposed at the first end of the bracket body and between the plurality of connecting rods;

[0008] The first ring is set on the positioning rod, and the top of the first ring is surrounded by several springs corresponding to the connecting rod.

[0009] The second collar is disposed on the positioning rod and below the first collar. At least two pivot seats are provided around the outer wall of the second collar. The anti-compression limiting component disposed on the pivot seat is used to eliminate the force on the first collar.

[0010] A receiving ring is disposed at the second end of the support body, and a multi-functional auxiliary component is disposed on the receiving ring.

[0011] As a further improvement, the pressure-resistant limiting assembly includes a shaft rotatably mounted on the pivot seat, a stress plate mounted on the shaft, a slider mounted at one end of the stress plate, a support platform mounted on the pivot seat and positioned below the stress plate, and a support member mounted on top of the support platform for supporting the stress plate.

[0012] As a further improvement, a transition section is formed at the top of the support member.

[0013] As a further improvement, the bottom of the first collar is provided with several sliding tracks that correspond to and slide with the slider.

[0014] As a further improvement, the multifunctional auxiliary component includes a limiting groove formed in the middle of the receiving ring, a plurality of insertion grooves formed on the limiting groove, a frustum detachably connected to the limiting groove, and a plurality of insertion rods disposed on the top of the frustum and corresponding to the insertion grooves.

[0015] As a further improvement, the outer wall of the receiving ring is provided with a plurality of clamping brackets, and bolts are provided on the clamping brackets.

[0016] As a further improvement, a cross-shaped reinforcing frame is provided at the bottom center of the bracket body to provide reinforcement, and a positioning post is provided on the cross-shaped reinforcing frame.

[0017] As a further improvement, one end of the positioning rod is threaded with a nut.

[0018] The beneficial effects of this utility model are:

[0019] (1) When one end of the support body sinks or tilts due to the weight of the amphibious vehicle, the spring at the top of the first ring will deform to absorb and offset part of the pressure, protecting the support body from damage. If the pressure continues to increase, the second ring will be stressed, causing the stress plate on the pivot to slide outward on the slide rail through the slider. At the same time, the coil spring structure between the shaft and the pivot provides traction to help buffer and disperse the pressure, preventing the support body from being damaged due to excessive pressure. This design absorbs and disperses the pressure through the spring and sliding limit assembly, protecting the support body from damage when subjected to heavy pressure. Furthermore, the plug rod can quickly connect the truncated cone to the plug slot, and the plugged truncated cone facilitates the connection between the support body and the floating platform. After the truncated cone is installed, it is convenient to connect the support body to the lifting device. Therefore, the structure designed in this case is not only suitable for land maintenance, but also for connection structures on the sea surface. Attached Figure Description

[0033] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model.

Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely to represent selected embodiments of this utility model.

[0034] In the description of this utility model, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

[0035] Reference Figure 1-5 As shown, an amphibious vehicle with a chassis folding support includes a support body 1 mounted on the chassis of the amphibious vehicle and several connecting rods 10 mounted at the first end of the support body 1.

[0036] A positioning rod 2 is located at the first end of the bracket body 1 and between several connecting rods 10. One end of the positioning rod 2 is threaded with a nut 5, which can be tightened to fix one end of the positioning rod 2 to prevent the first collar 3 and the second collar 4 from falling off. The first collar 3 is located on the positioning rod 2, and several springs 30 corresponding to the connecting rods 10 are arranged around the top of the first collar 3. The second collar 4 is located on the positioning rod 2 and below the first collar 3. At least two pivot seats 40 are arranged around the outer wall of the second collar 4. Anti-compression limiting components are arranged on the pivot seats 40 to eliminate the force on the first collar 3. The compression limiting assembly includes a shaft 42 rotatably mounted on the pivot seat 40, a stress plate 43 mounted on the shaft 42, a slider 44 mounted at one end of the stress plate 43, a support platform 45 mounted on the pivot seat 40 and positioned below the stress plate 43, a support member 46 mounted on the top of the support platform 45 and used to support the stress plate 43, and a plurality of slide rails 31 corresponding to and sliding with the slider 44 at the bottom of the first ring 3.

[0037] To ensure the support body 1 remains undamaged when used as a land-based maintenance auxiliary component, a first collar 3 and a second collar 4 are sequentially installed on the positioning rod 2. When the second end of the support body 1 connects to the lifting device, the first end of the support body 1 will inevitably experience significant pressure due to the large mass of the amphibious vehicle, causing it to tilt slightly. To prevent damage to the first end due to excessive force, a spring 30 at the top of the first collar 3 is connected to a connecting rod 10, with the connecting rod 10 inserted into the middle of the spring 30 and fixed in place. When the first end of the support body 1 tilts slightly, the spring 30 deforms, thus offsetting the force on the first end of the support body 1. Furthermore, when the first end of the support body 1 is pressed down, the second collar 4 will also experience a certain force. After the second collar 4 is subjected to force, the stress on the pivot seat 40 will be reduced. The stress plate 43 slides outward on the slide rail 31 via the slider 44, and a coil spring structure (existing technology, not described in detail here) is provided between the shaft 42 and the pivot seat 40. This allows the stress plate 43 to have a traction force after being subjected to force, thereby achieving a buffering and pressure reduction effect. When on the sea surface, since it is necessary to fix the amphibious vehicle on the floating platform, the support body 1 can be folded outward. The frustum 82 in the receiving ring 8 at the second end of the support body 1 is removed from the receiving ring 8, exposing the limiting groove 80. The limiting groove 80 is connected to the connecting structure on the floating platform, and the clamping frame 84 and bolt 85 can lock and fix the support body 1 on the floating platform to ensure the stability of the amphibious vehicle. Therefore, this structural design is not only suitable for the maintenance of amphibious vehicles, but also for other occasions that require support and buffering.

[0038] Furthermore, a transition section is formed at the top of the support member 46. This transition section serves to provide support when the stress plate 43 is compressed under force.

[0039] A receiving ring 8 is disposed at the second end of the bracket body 1, and a multi-functional auxiliary component is disposed on the receiving ring 8. The multi-functional auxiliary component includes a limiting groove 80 formed in the middle of the receiving ring 8, a plurality of insertion grooves 81 formed in the limiting groove 80, a frustum 82 detachably connected to the limiting groove 80, and a plurality of insertion rods 83 disposed on the top of the frustum 82 and corresponding to the insertion grooves 81.

[0040] It should be noted that the frustum 82 can be quickly connected to the connector slot 81 via the connector rod 83. After the frustum 82 is connected, it facilitates the connection between the support body 1 and the floating platform. Furthermore, after the frustum 82 is installed, it facilitates the connection between the support body 1 and the lifting device. Therefore, the structure designed in this case is not only suitable for land-based maintenance but also for connection structures on the sea surface.

[0041] Furthermore, the outer wall of the receiving ring 8 is surrounded by several clamping frames 84, and bolts 85 are provided on the clamping frames 84.

[0042] When the amphibious vehicle is on land, it needs to be supported for maintenance. Therefore, the four support bodies 1 are rotated outwards via positioning rods 2, and the receiving ring 8 on the second end of the support body 1 is connected to the lifting device in the prior art. The second end of the support body 1 is locked and fixed to the lifting device by clamping frame 84 and bolts 85. Compared with the chassis iron block structure in the prior art, the structure in this case can not only achieve the function of connecting the iron block to the lifting device, but also, when it is inconvenient to connect the lifting device to the amphibious vehicle, the foldable support body 1 can be folded outwards, and the clamping frame 84 and bolts 85 can be connected and fixed to the lifting device.

[0043] A cross-shaped reinforcing frame 6 is provided at the bottom center of the support body 1 for reinforcement, and a positioning post 7 is provided on the cross-shaped reinforcing frame 6. The cross-shaped reinforcing frame 6 is used to increase the strength of the support body 1 and prevent it from breaking. Furthermore, when the amphibious vehicle is fixed on the water surface, the positioning post 7 on the cross-shaped reinforcing frame 6 can correspond to the corresponding connection structure on the floating platform on the water surface (for example, the floating platform is provided with a corresponding connection hole, which is connected to the positioning post 7), thereby improving the stability of the hull.

[0044] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
