Description
Technical Field
[0001] This utility model belongs to the field of attitude adjustment vehicle technology, and more specifically, relates to an attitude adjustment vehicle based on rear end surface support. Background Technology
[0002] As a type of mechanical equipment capable of flexibly adjusting its posture according to different working conditions and terrain, the attitude adjustment vehicle has a wide range of applications in many fields such as industrial production, engineering construction, and logistics transportation. On industrial assembly lines, the attitude adjustment vehicle can precisely adjust its height and angle, facilitating the installation and debugging of parts by workers. In engineering operations on complex terrains, the attitude adjustment vehicle can maintain stability through posture adjustment, ensuring construction safety and efficiency. In logistics transportation scenarios, the attitude adjustment vehicle can adapt to loading and unloading platforms of different heights, improving the convenience of cargo transfer. It can be said that the performance of the attitude adjustment vehicle directly affects the effectiveness of related work.
[0003] Traditional attitude adjustment vehicles based on rear-end support typically employ fixed structures or simple mechanical transmission support components, such as common hydraulic lifting columns and screw-type support legs. These vehicles exhibit numerous drawbacks when facing complex and varied ground environments. Firstly, their support structures lack flexibility and struggle to adapt to irregular ground shapes. For example, on uneven construction sites or soft muddy ground, traditional support components cannot maintain a tight fit, leading to instability, swaying, or even overturning, affecting operational accuracy and posing safety hazards. Secondly, traditional attitude adjustment vehicles offer limited adjustment methods, often relying on linear lifting or simple angle adjustments, failing to meet diverse work requirements. Furthermore, the coordination between components during attitude adjustment is poor, lacking an effective linkage mechanism, resulting in low efficiency and an inability to quickly respond to actual work attitude adjustment needs. Additionally, traditional attitude adjustment vehicles have limited gripping capabilities, easily slipping and shifting on slopes, smooth surfaces, and other special working conditions, further limiting their application range. Utility Model Content
[0004] In view of this, the present invention provides an attitude adjustment vehicle based on rear end surface support, which solves the problems of poor adaptability of traditional attitude adjustment vehicles based on rear end surface support on complex terrain and the single attitude adjustment method, and realizes flexible attitude adjustment and stable support of the attitude adjustment vehicle.
[0005] This utility model is implemented as follows:
[0006] This utility model provides a posture adjustment vehicle based on rear end support, which includes a vehicle body, a honeycomb deformable frame, a ground gripping spike assembly, and a front triangular fork; the honeycomb deformable frame is disposed on the rear end face of the vehicle body, the ground gripping spike assembly is installed at the bottom of the honeycomb deformable frame, and the front triangular fork is installed on the front end face of the vehicle body.
[0007] The technical advantages of the attitude adjustment vehicle based on rear-end support provided by this utility model are as follows: It clearly defines the core components of the attitude adjustment vehicle and their basic positional relationships, giving the vehicle a complete support and attitude adjustment architecture. The vehicle body serves as the basic load-bearing structure, with a honeycomb deformable frame located at the rear end to provide primary adaptive support. Ground-grip components enhance the stability of the frame's connection to the ground, and the front triangular fork assists in achieving multi-angle attitude adjustment. All components cooperate to form a fully functional attitude adjustment vehicle system.
[0008] Based on the above technical solution, the attitude adjustment vehicle based on rear end support of this utility model can be further improved as follows:
[0009] The honeycomb deformable frame is composed of an array of multiple hexagonal units. Each hexagonal unit is formed by six retractable elastic metal rods that are hinged end to end in sequence. Adjacent hexagonal units are connected by flexible hinges.
[0010] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: the honeycomb deformable frame adopts a hexagonal unit array structure, which utilizes the geometric stability of hexagons to maintain good structural strength during deformation; the elastic metal rods are hinged at both ends and connected by flexible hinges, allowing the frame to deform freely according to the undulations of the ground and fit closely to the ground, thereby providing stable and adaptive support for the attitude adjustment vehicle and significantly improving the vehicle's applicability in complex terrain.
[0011] Furthermore, the elastic metal rod includes an inner rod and an outer rod, the inner rod being slidably fitted inside the outer rod, and an elastic element for providing telescopic elastic force is provided between the inner rod and the outer rod.
[0012] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: the inner and outer rods of the elastic metal rod cooperate with the elastic element to provide elastic force for extension and contraction, so that the metal rod can flexibly deform to adapt to changes in the ground during the extension and contraction process, and can also provide a certain support and buffer force when under stress, further enhancing the self-adaptive ability and structural stability of the honeycomb deformable frame, and reducing the vibration and impact of the vehicle during the attitude adjustment process.
[0013] Furthermore, the ground anchor assembly includes multiple ground anchors, and the bottom of the honeycomb deformable frame is provided with mounting slots corresponding to the number of ground anchors. Each ground anchor is installed in the corresponding mounting slot by a spring, and the ground anchor can be ejected from the mounting slot and embedded in the ground under the action of the spring force.
[0014] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: the grip studs are installed in the mounting groove at the bottom of the honeycomb deformable frame by means of springs. When the frame contacts the ground, the grip studs automatically pop out and embed into the ground under the action of spring force, which effectively prevents the vehicle from sliding or shifting on complex ground, greatly enhances the vehicle's grip and stability, and is especially suitable for soft, muddy and other slippery ground.
[0015] Furthermore, the grip spike is conical, and the end of the grip spike facing the ground has multiple spikes.
[0016] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: the cone-shaped grip stud design with spikes at the end can penetrate the ground more easily, increase the contact area and friction with the ground, and further improve the grip effect. Even in extremely harsh ground conditions, it can ensure the stability of the vehicle and prevent the vehicle from shaking or overturning.
[0017] Furthermore, the front triangular fork includes three legs and a connecting seat. One end of each of the three legs is connected to the connecting seat via a rotating joint. The connecting seat is fixedly installed on the front face of the vehicle body. Each leg can rotate around its connection point with the connecting seat to adjust its angle.
[0018] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: the three legs of the front triangular fork are connected to the connecting seat through a rotating joint, and the legs can be rotated to adjust the angle, so that the triangular fork can flexibly adjust its posture according to different terrains and posture adjustment requirements. In conjunction with the rear honeycomb deformable frame, it can achieve precise posture adjustment of the posture adjustment vehicle in multiple dimensions, thus expanding the working range and applicability of the vehicle.
[0019] Furthermore, the rotating pair includes a rotating hole formed on the connecting seat and a rotating shaft fixed on the support leg. The rotating shaft is rotatably installed in the rotating hole, and a limiting structure is provided between the rotating shaft and the rotating hole to limit the position of the support leg after rotation.
[0020] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: the structural design of the rotating hole and rotating shaft in the rotating joint ensures the flexibility of the outrigger rotation, while the limiting structure can fix the outrigger after it is adjusted to a suitable angle, preventing the outrigger from rotating arbitrarily due to force during vehicle operation, ensuring the stability of the triangular fork after posture adjustment, thereby improving the overall reliability and safety of the posture adjustment vehicle.
[0021] Pin-hole type limiting structure: Multiple limiting holes are spaced axially on the circumferential surface of the rotating shaft; simultaneously, through holes are provided on the sidewalls corresponding to the rotating holes, and sliding limiting pins are installed in the through holes. When it is necessary to adjust the angle of the support leg, pull the limiting pin outward to disengage it from the limiting hole on the rotating shaft, allowing the support leg to rotate freely; after the support leg is adjusted to the appropriate angle, release the limiting pin, and under the action of spring or gravity, the limiting pin inserts into the corresponding limiting hole, thereby restricting the rotation of the rotating shaft and fixing the angle of the support leg. This structure is simple and intuitive, easy to operate, and can achieve various angle limiting through the limiting holes in different positions.
[0022] The slot-and-block limiting structure consists of multiple annular slots machined circumferentially on the outer surface of the rotating shaft. A retractable block is installed on the inner wall of the rotating hole. The block is connected to the inner wall of the rotating hole via a spring. Initially, the block partially extends into the rotating hole under the spring force. When the rotating shaft rotates, the block is compressed back. When the slot on the rotating shaft rotates to correspond to the position of the block, the block engages with the slot under the spring force, preventing the rotating shaft from rotating further and thus limiting the angle of the support leg. This structure allows for continuous angle adjustment, and the cooperation between the block and the slot provides good limiting stability.
[0023] Ratchet-Pawl Type Limiting Structure: One end of the rotating shaft is designed as a ratchet structure, with the ratchet teeth evenly distributed circumferentially. A pawl, capable of rotating around a fixed shaft, is installed at the corresponding position of the rotating hole. The pawl is connected to the inner wall of the rotating hole via a torsion spring, ensuring that the pawl always tends to engage with the ratchet teeth. When it is necessary to rotate the foot, the pawl is disengaged from the ratchet by overcoming the spring force, allowing the rotating shaft to rotate. After rotation, the pawl is released, and under the action of the torsion spring, the pawl re-engages with the ratchet teeth, preventing the rotating shaft from reversing and thus fixing the foot angle. This structure effectively prevents the foot from rotating under force and is suitable for posture adjustment scenarios that require withstanding large external forces.
[0024] The threaded knob-type limiting structure features a threaded hole machined into the side wall of the rotating hole, into which a limiting knob is screwed. A radial limiting groove is correspondingly formed on the rotating shaft. Once the support leg is adjusted to the appropriate angle, the limiting knob is tightened, causing its end to extend into the limiting groove on the rotating shaft, preventing rotation and fixing the support leg angle. The limiting force of the support leg can be finely adjusted by rotating the knob. This structure is convenient to operate and facilitates later maintenance and adjustment.
[0025] Furthermore, the top of the honeycomb deformable frame is hinged to the rear end face of the vehicle body through multiple hinge points, which are distributed at intervals along the top edge of the honeycomb deformable frame.
[0026] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: the top of the honeycomb deformable frame is hinged to the rear end face of the vehicle body through multiple spaced hinge points, which allows the frame to rotate flexibly around the hinge points during deformation. At the same time, multiple hinge points ensure the stability of the connection between the frame and the vehicle body, preventing the frame from detaching from the vehicle body or causing abnormal shaking during deformation, thus ensuring the smooth progress of the attitude adjustment process and the safety of the vehicle.
[0027] Furthermore, the bottom of the vehicle body is provided with support wheels for auxiliary support, and the support wheels are located between the honeycomb deformable frame and the front triangular fork.
[0028] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: the support wheel located at the bottom of the vehicle body between the honeycomb deformable frame and the front triangular fork plays an auxiliary support and guiding role during the movement of the attitude adjustment vehicle, which facilitates the movement and positioning of the vehicle; during the attitude adjustment process, the support wheel can share part of the vehicle weight, reduce the pressure on the honeycomb deformable frame and the front triangular fork, extend their service life, and improve the flexibility and stability of the vehicle attitude adjustment.
[0029] Furthermore, the flexible hinge is a bendable metal sheet, and both ends of the metal sheet are fixedly connected to the elastic metal rods of adjacent hexagonal units.
[0030] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: the flexible hinge uses a bendable metal sheet, whose two ends are fixedly connected to the elastic metal rod. It has good flexibility and strength, and can ensure that the adjacent hexagonal units are tightly connected while allowing the frame to deform freely, ensuring the smoothness and stability of the honeycomb deformable frame, and improving the overall performance and service life of the frame.
[0031] Compared with the prior art, the beneficial effects of the attitude adjustment vehicle based on rear end support provided by this utility model are:
[0032] In terms of adaptability, the honeycomb deformable frame, with its hexagonal unit array structure and the connection method of retractable elastic metal rods and flexible hinges, can highly adaptively conform to various complex terrain shapes. Whether it's rugged mountains, potholed roads, or uneven steps, the frame can freely deform under pressure or tension, making the entire vehicle like a "flexible skeleton," closely contacting the ground and ensuring stable support. The addition of traction spikes further enhances the vehicle's grip on complex terrain. The conical traction spikes with spikes automatically pop out and embed into the ground under the action of springs, firmly fixing the vehicle even on slippery surfaces such as soft sand and muddy swamps, preventing slippage and greatly expanding the application scenarios of the vehicle.
[0033] In terms of flexibility and precision in posture adjustment, the front triangular fork and the rear honeycomb deformable frame form a highly efficient collaborative posture adjustment mechanism. The three legs of the triangular fork can be flexibly rotated and adjusted in angle through the rotating joints, and with the precise positioning of the limiting structure, it can perform fine-tuning of posture in multiple dimensions. Combined with the rear deformable frame, it can realize multi-angle and multi-directional posture adjustment of the posture adjustment vehicle in space. Whether it is tilting operation, lateral adjustment, or height change, it can be completed accurately and quickly, meeting diverse work needs.
[0034] From the perspective of structural stability and durability, the honeycomb deformable frame is hinged to the rear end of the vehicle body at multiple hinge points, ensuring a stable connection during deformation and preventing structural damage caused by uneven stress. Support wheels are located between the frame and the triangular fork, effectively distributing the vehicle's weight during movement and adjustment, reducing pressure on other support components, and extending the overall structural lifespan. The flexible hinges, using bendable metal sheets, ensure smooth frame deformation while possessing good strength and toughness, guaranteeing a tight connection between adjacent hexagonal units and improving the overall performance and durability of the frame.

[0041] 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.
[0042] like Figures 1-3 The figure shows a first embodiment of a posture adjustment vehicle based on rear end support provided by this utility model. In this embodiment, it includes a vehicle body 10, a honeycomb deformable frame 20, a ground gripping spike assembly 30, and a front triangular fork 40. The honeycomb deformable frame 20 is disposed on the rear end face of the vehicle body 10, the ground gripping spike assembly 30 is installed at the bottom of the honeycomb deformable frame 20, and the front triangular fork 40 is installed on the front end face of the vehicle body 10.
[0043] The attitude adjustment vehicle is moved to the working position, and the rear honeycomb deformable frame and the front triangular fork adjust the attitude in coordination according to the ground conditions, providing a stable support foundation for subsequent work.
[0044] In the above technical solution, the honeycomb deformable frame 20 is composed of an array of multiple hexagonal units 21. Each hexagonal unit 21 is formed by six retractable elastic metal rods 211 that are hinged end to end in sequence, and adjacent hexagonal units 21 are connected by flexible hinges.
[0045] When the attitude adjustment vehicle travels on uneven ground, the honeycomb deformable frame at the rear end is subjected to compression or tension from the ground. The hexagonal units deform through elastic metal rods and flexible hinges, automatically adapting to the shape of the ground to achieve stable support.
[0046] Furthermore, in the above technical solution, the elastic metal rod 211 includes an inner rod and an outer rod, the inner rod is slidably sleeved inside the outer rod, and an elastic element for providing telescopic elastic force is provided between the inner rod and the outer rod.
[0047] As the honeycomb deformable frame adapts to the shape of the ground, the inner rod of the elastic metal rod slides inside the outer rod, the elastic element compresses or extends, and the length of the metal rod is adjusted to ensure that the frame fits tightly to the ground, while buffering the impact force from the ground.
[0048] Furthermore, in the above technical solution, the ground gripping spike assembly 30 includes multiple ground gripping spikes, and the bottom of the honeycomb deformable frame 20 is provided with an installation groove corresponding to the number of ground gripping spikes. Each ground gripping spike is installed in the corresponding installation groove by a spring, and the ground gripping spike can be ejected from the installation groove and embedded in the ground under the action of the spring force.
[0049] Furthermore, in the above technical solution, the grip spike is conical, and the end of the grip spike facing the ground has multiple spikes.
[0050] Furthermore, in the above technical solution, the front triangular fork 40 includes three legs 41 and a connecting seat 42. One end of the three legs 41 is connected to the connecting seat 42 through a rotating joint. The connecting seat 42 is fixedly installed on the front face of the vehicle body 10. Each leg can rotate around its connection with the connecting seat to adjust the angle.
[0051] Furthermore, in the above technical solution, the rotating pair includes a rotating hole opened on the connecting seat and a rotating shaft fixed on the support leg. The rotating shaft is rotatably installed in the rotating hole, and a limiting structure is provided between the rotating shaft and the rotating hole to limit the position of the support leg after rotation.
[0052] Furthermore, in the above technical solution, the top of the honeycomb deformable frame 20 is hinged to the rear end face of the vehicle body 10 through multiple hinge points, and the multiple hinge points are distributed at intervals along the top edge of the honeycomb deformable frame 20.
[0053] Furthermore, in the above technical solution, the bottom of the vehicle body 10 is provided with a support wheel for auxiliary support, and the support wheel is located between the honeycomb deformable frame 20 and the front triangular fork 40.
[0054] When the vehicle is moving, the support wheels are in contact with the ground to assist in driving and steering; during attitude adjustment, the support wheels support part of the vehicle's weight, making it easier for the honeycomb deformable frame and the front triangular fork to adjust the attitude and helping to maintain the vehicle's balance.
[0055] Furthermore, in the above technical solution, the flexible hinge is a bendable metal sheet, and the two ends of the metal sheet are respectively fixedly connected to the elastic metal rods 211 of the adjacent hexagonal unit 21.
[0056] Specifically, the principle of this utility model is as follows:
[0057] The design of the honeycomb deformable frame is inspired by the stable hexagonal structure of a honeycomb. The hexagon possesses unique geometric stability, evenly distributing forces and ensuring the frame maintains good structural strength during deformation. The retractable elastic metal rods within the frame consist of inner rods, outer rods, and elastic elements. Their principle is similar to a telescopic rod; the sliding of the inner rod within the outer rod, combined with the expansion and contraction of the elastic element, allows the metal rods to automatically adjust their length according to the magnitude and direction of the ground forces, thus achieving frame deformation. Adjacent hexagonal units are connected by flexible hinges. This connection method ensures both relative freedom of movement between units and maintains the overall integrity of the frame, allowing it to bend flexibly like a biological joint, adapting to various complex terrains.
[0058] The working principle of the traction spike assembly is based on friction and mechanical embedding. The traction spikes are spring-loaded into mounting slots at the bottom of a honeycomb-shaped deformable frame. When the frame contacts the ground, the spring force propels the traction spikes, causing them to embed into the ground. The conical design with spikes increases the contact area and friction between the traction spikes and the ground. Simultaneously, the spikes can embed into gaps in the ground or soil layers, forming a mechanical lock, thus greatly enhancing the connection strength between the vehicle and the ground and effectively preventing vehicle slippage.
[0059] The front triangular fork uses a revolute joint to connect the outriggers and the connecting seat, utilizing lever principles and rotational motion to adjust the outrigger angle. The engagement of the rotating shaft and rotating hole allows the outriggers to rotate freely around the shaft, while the limiting structure, based on mechanical locking principles, uses pin-hole engagement and locking block locking to restrict the rotation of the rotating shaft after the outriggers are adjusted to the appropriate angle, thus fixing the angle. This structural design allows the triangular fork to adjust its posture in multiple directions, working in conjunction with the rear honeycomb deformable frame to jointly complete the posture adjustment of the vehicle.
