Description

Technical Field

[0001] The present invention relates to the technical field of anti-collision buffering for vehicles, and specifically refers to an anti-collision buffering device. Background Art

[0002] In transportation and engineering operations, vehicles or mobile devices may collide during driving or operation. To protect the safety of vehicles and personnel, anti-collision buffering devices are usually installed at the front end of the vehicle or in the operation area. The existing anti-collision buffering devices mainly include the following types:

[0003] Rigid frame structure: This structure is usually composed of a strong metal frame and can withstand large impact forces. However, the rigid frame structure cannot effectively absorb energy during a collision, resulting in the impact force being directly transmitted to the vehicle or device, which may cause serious damage.

[0004] Single energy-absorbing material: Some anti-collision buffering devices use single energy-absorbing materials such as foam and honeycomb aluminum. These materials can effectively absorb energy during low-speed collisions, but under high-speed collisions or large impact forces, they are prone to permanent deformation or damage, resulting in a decrease in the energy-absorbing effect.

[0005] Single-stage energy-absorbing structure: Some anti-collision devices are designed with a single-stage energy-absorbing structure, that is, a single energy-absorbing unit is used to absorb the collision energy. This structure has limitations in energy-absorbing efficiency and cannot effectively reduce the peak impact force, making it easy for the vehicle or device to roll over or be severely damaged during a collision.

[0006] Currently, the deficiencies of the existing technology are mainly reflected in the following aspects:

[0007] 1. Low energy-absorbing efficiency: The rigid frame structure and single energy-absorbing material have low energy-absorbing efficiency when facing large impact forces and cannot effectively protect the safety of vehicles and personnel.

[0008] 2. Poor structural stability: The single-stage energy-absorbing structure is prone to local deformation or damage during a collision, resulting in a decrease in the overall structural stability.

[0009] 3. Large peak impact force: Existing anti-collision devices are difficult to effectively reduce the peak impact force during the process of absorbing collision energy, and are likely to cause secondary damage to vehicles or devices.

[0010] Therefore, an anti-collision buffering device is proposed to solve the existing deficiencies. Summary of the Invention

[0011] The technical problem to be solved by the present invention is to overcome the above-mentioned technical defects and provide an anti-collision buffering device.

[0012] To solve the above technical problems, the technical solution provided by the present invention is an anti-collision buffer device: including an anti-collision frame and a guard plate arranged on the outside of the anti-collision frame;

[0013] The anti-collision frame includes a frame one and a frame two connected to one end of the frame one. The frame two forms a buffer zone one, and the frame two is filled with foam. The inside of the frame one is divided into a buffer zone one and a buffer zone two by a partition. A plurality of anti-collision beam groups are arranged in the buffer zone one, and multiple layers of buffer grid groups are arranged in the buffer zone two;

[0014] A set of connecting rods is vertically arranged at the other end of the frame one, and a connecting plate is arranged between the connecting rods of the frame one.

[0015] As an improvement, the cross-section of the frame two is in a horizontally placed C-shaped structure.

[0016] As an improvement, the inside of the frame one is equally divided into a buffer zone one and a buffer zone two by a partition, and the buffer zone one is located between the frame two and the buffer zone two.

[0017] As an improvement, the number of the anti-collision beam groups is [X] and they are evenly arranged in the buffer zone one along the width direction of the frame one. Each anti-collision beam group includes a plurality of anti-collision beams arranged at intervals along the height direction of the frame one.

[0018] As an improvement, multiple buffer grid groups are arranged at intervals along the height direction of the frame one in the buffer zone two. Each buffer grid group includes a plurality of splicing units connected in sequence, and the plurality of splicing units as a whole has a honeycomb-shaped cross-section structure.

[0019] As an improvement, the splicing unit is a tubular structure with a polygonal cross-section.

[0020] As an improvement, the side of the splicing unit connected to the adjacent splicing unit is an inward concave structure.

[0021] As an improvement, the splicing unit is a pentagon.

[0022] The advantages of the present invention compared with the prior art are as follows:

[0023] 1. Adopting a multi-stage energy absorption structure, through the coordinated work of the buffer zone one and the buffer zone two inside the frame one, the hierarchical absorption of energy is realized, which can more effectively utilize the energy absorption materials in each area and improve the overall energy absorption efficiency. At the same time, the internal space of the frame one is equally divided into two independent energy absorption areas by a partition, so that the impact force can be more evenly distributed between the two buffer zones, avoiding excessive concentrated loads on a single area and improving the stability and durability of the device.

[0024] 2. The interior of Frame Two is filled with foam. Thanks to the elastic deformation characteristics of the foam, it can effectively absorb low-speed collision energy. The foam filling design shows a more excellent energy absorption effect during low-speed collisions. At the same time, the combination of foam filling and the C-shaped frame forms a preliminary energy absorption unit, which can absorb a part of the energy at the initial stage of the collision, reducing the burden on subsequent energy absorption components. The multi-level energy absorption design improves the overall energy absorption efficiency of the device.

[0025] 3. The anti-collision beam group is made of thin-walled metal, and its cross-section is a horizontally placed "C" shape. It absorbs kinetic energy through local buckling and fracture, and can undergo more effective plastic deformation during the collision process to absorb more energy. At the same time, the anti-collision beam group is arranged at intervals along the height direction of Frame One to form a cross-bracing structure, which not only enhances the overall impact resistance ability but also maintains the integrity of the device during the collision process, avoiding overall failure caused by local deformation.

[0026] 4. The buffer grid group adopts a honeycomb structure, which has high specific stiffness and uniform stress distribution characteristics. The honeycomb structure can more effectively disperse the impact force and improve the energy absorption efficiency. At the same time, the splicing unit of the buffer grid group is a regular pentagon, which disperses the impact force through multi-point contact, reduces local stress concentration, effectively improves the overall energy absorption efficiency, and reduces the impact of the peak impact force on the device.

[0027] 5. Through multiple means such as multi-level energy absorption structures, C-shaped frame design, foam filling, anti-collision beam group, and buffer grid group, multiple functions such as efficient energy absorption and uniform load distribution are achieved. There are significant improvements in aspects such as energy absorption efficiency, structural stability, and safety. At the same time, through multi-level and multi-stage energy absorption design, the peak impact force can be effectively reduced, minimizing secondary damage to vehicles or equipment, achieving more efficient and safer collision energy absorption, and providing more reliable protection for vehicles and personnel.

[0039] To make the objectives, technical solutions and advantages of the embodiments of the invention clearer, the technical solutions in the embodiments of the invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the invention. Apparently, the described embodiments are some but not all of the embodiments of the invention. Generally, the components of the embodiments of the invention described and illustrated in the accompanying drawings here can be arranged and designed in various different configurations.

[0040] In the description of the embodiments of the invention, it should be noted that if terms such as "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. are used to indicate the orientation or positional relationship, it is based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship in which the product of the invention is usually placed during use. It is only for the convenience of describing the invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be construed as a limitation of the invention. In addition, terms such as "first", "second", "third", etc. are only used for descriptive distinction and cannot be understood as indicating or implying relative importance.

[0041] In addition, if terms such as "horizontal", "vertical", "hanging" are used, it does not mean that the component is required to be absolutely horizontal or hanging, but can be slightly inclined. For example, "horizontal" only means that its direction is more horizontal relative to "vertical", and does not mean that the structure must be completely horizontal, but can be slightly inclined.

[0042] In the description of the embodiments of the invention, "a plurality of" represents at least two.

[0043] In the description of the embodiments of the invention, it should also be noted that unless otherwise clearly specified and limited, if the terms "set", "installed", "connected", and "linked" appear, they should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the invention can be understood according to specific circumstances.

[0044] As shown in the accompanying drawings, an anti-collision buffer device includes an anti-collision frame 1 and a guard plate 2 arranged outside the anti-collision frame 1;

[0045] The anti-collision frame 1 is the basic structure of the overall structure, providing stable support for other components of the device to ensure that each component can work properly during the collision process;

[0046] At the same time, the frame 1 itself also bears a part of the impact force and transmits the impact force to other energy-absorbing components through its own structure.

[0047] The guard plate 2 is located outside the anti-collision frame 1 and is used to initially contact and disperse the impact force; specifically, the guard plate 2 is the first barrier between the device and the impact object. The guard plate 2 first bears the impact force and can initially disperse the concentrated impact force to reduce the direct impact on the subsequent energy-absorbing components.

[0048] The anti-collision frame 1 includes a frame one 11 and a frame two 12 connected to one end of the frame one 11. The frame one 11 provides an installation basis for the energy-absorbing components of the anti-collision beam group 7 and the buffer grid group 8, and at the same time, through its own firmness, protects the internal energy-absorbing components from direct impact.

[0049] The frame two 12 forms a buffer zone one 13. The frame two 12 is filled with foam 3. The cross-section of the frame two 12 is in a horizontally placed C-shaped structure. The horizontally placed C-shaped cross-section design of the frame two 12 can provide stable lateral support, and at the same time, the foam 3 filled inside it can absorb low-speed collision energy through elastic deformation.

[0050] At the same time, the C-shaped structure of the frame two 12 can guide the collision direction, making the impact force transmit along the longitudinal direction of the frame to avoid vehicle rollover caused by lateral offset.

[0051] The inside of the frame one 11 is separated into a buffer zone two 5 and a buffer zone three 6 by a partition 4, forming a multi-stage energy-absorbing structure, and then gradually absorbing and dispersing the collision energy in a staged and zoned manner, thereby improving the overall energy-absorbing efficiency and the stability of the device.

[0052] Specifically, the inside of the first frame 11 is equally divided into a second buffer area 5 and a third buffer area 6 by partition bars. The second buffer area 5 is located between the second frame 12 and the third buffer area 6. During implementation, the second buffer area 5 is close to the second frame 12 and preferentially bears the impact. The second buffer area 5 first bears the collision impact force and conducts preliminary energy absorption. The anti-collision beam group 7 in the second buffer area 5 undergoes plastic deformation to absorb energy. The third buffer area 6 is located at the rear end and further disperses the energy through a multi-layer structure, that is, the third buffer area 6 receives the remaining energy transmitted from the second buffer area 5 and conducts secondary energy absorption, and conducts progressive energy absorption through the buffer grid group 8. Therefore, through multi-stage energy absorption, the energy absorption materials in each area can be more effectively utilized, the overall energy absorption efficiency can be improved, and the concentrated load on a certain area caused by a single impact can be reduced, thereby improving the stability and durability of the device.

[0053] A plurality of anti-collision beam groups 7 are provided in the second buffer area 5;

[0054] Specifically, the number of the anti-collision beam groups 7 is 2, and they are evenly arranged in the second buffer area 5 along the width direction of the first frame 11. The anti-collision beam group 7 includes a plurality of anti-collision beams 71 spaced along the height direction of the first frame 11, which can form a cross-support structure and absorb energy through the plastic deformation of the beam body.

[0055] In this embodiment, the anti-collision beam 71 is made of thin-walled metal, and its cross-section is in a horizontally placed "C" shape, providing good support in the horizontal direction, enhancing the bending resistance of the anti-collision beam, absorbing kinetic energy through local buckling and fracture during collision, and avoiding concentrated energy transfer through the interval design.

[0056] During implementation, when a collision occurs, the "C" structure of the anti-collision beam 71 will first undergo local buckling. This buckling process can absorb a part of the collision energy.

[0057] As the collision force increases, the anti-collision beam 71 will further break, and at this time, the breaking process can also absorb kinetic energy.

[0058] At the same time, the anti-collision beams 71 are spaced along the height direction of the first frame 11, which can avoid concentrated energy transfer. That is, the impact force is dispersed to a plurality of anti-collision beams 71, avoiding a single beam from bearing too much load. Furthermore, through the sequential deformation of the plurality of anti-collision beams 71, the time of the energy absorption process is extended, and the peak impact force is reduced.

[0059] A multi-layer buffer grid group 8 is provided in the third buffer area 6, and through a progressive energy absorption path and a honeycomb structure, the peak impact force is further reduced and the overall energy absorption efficiency is improved.

[0060] A plurality of the buffer grid groups 8 are arranged at intervals in the third buffer area 6 along the height direction of the first frame 11. The multi-layer buffer grid groups 8 are stacked along the height direction to form a progressive energy absorption path, which can gradually absorb and disperse the impact force and reduce the influence of the peak impact force on the device.

[0061] At the same time, the multi-layer buffer grid group 8 structure can ensure that the impact force is evenly dispersed and absorbed during the transmission process, avoiding excessive load on a single layer.

[0062] The buffer grid group 8 includes a plurality of splicing units 81 connected in sequence. The plurality of splicing units 81 as a whole has a honeycomb-shaped cross-section structure. The honeycomb-shaped structure has a high specific stiffness, that is, while ensuring strength, it can achieve lightweight, so that the buffer grid group 8 can maintain a high stiffness when bearing the impact force and avoid excessive deformation.

[0063] At the same time, the honeycomb-shaped structure can evenly distribute the impact force on multiple nodes, avoiding stress concentration, so that the buffer grid group 8 can more effectively disperse the impact force during the energy absorption process and improve the overall energy absorption efficiency.

[0064] The splicing unit 81 is a tubular structure with a polygonal cross-section. In this embodiment, the splicing unit 81 is a pentagon. The splicing unit 81 with a pentagon structure disperses the impact force through multi-point contact, reduces local stress concentration, and improves the overall energy absorption efficiency.

[0065] Furthermore, one side of the splicing unit 81 connected to the adjacent splicing unit 81 is an inward concave structure.

[0066] During a collision, the inward concave structure of the splicing unit 81 can guide the impact force to the central area of the splicing unit, avoiding diffusion to both sides, effectively preventing the impact force from spreading outwards, causing excessive stress on the edge part of the device, and thus reducing the risk of damage or detachment of the edge part.

[0067] A group of connecting rods 9 are vertically arranged at the other end of the first frame 11. During implementation, the top of the connecting rod 9 can be used to install a warning sign, such as "Under operation, please avoid".

[0068] A connecting plate 10 is arranged between the connecting rods 9 on the first frame 11. During implementation, a connecting nut (not shown in the figure) is welded on the connecting plate 10. At the same time, a fixing plate corresponding to the connecting plate 10 is arranged at the rear end of the vehicle, and a bolt matching with the nut is installed on the fixing plate, thereby realizing the fixed installation of the device on the vehicle.

[0069] The above describes the present invention and its implementation manners. Such description is not restrictive. What is shown in the drawings is only one of the implementation manners of the present invention, and the actual structure is not limited thereto. In general, if those of ordinary skill in the art are inspired by it and, without departing from the gist of the present invention, design similar structural manners and embodiments to this technical solution without creative efforts, they shall fall within the protection scope of the present invention.
