Description

Technical Field

[0001] The utility model relates to the technical field of vehicle frame assemblies, in particular to a vehicle frame assembly with buffering and energy absorbing functions. Background Art

[0002] The frame is a frame structure that spans the front and rear axles of the car, commonly known as the beam, and is the base of the car. It is generally composed of two longitudinal beams and several cross beams, and is supported on the wheels through the suspension device, the front axle, and the rear axle. The frame must have sufficient strength and rigidity to withstand the load of the car and the impact from the wheels.

[0003] The announcement number is: CN219257488U, and the disclosure is "a frame assembly with a buffering and shock-absorbing function, including a frame outer frame, three groups of connecting crossbeams are welded at equal intervals between the inner sides of the frame outer frame, and the lower ends of the left and right sides of the connecting crossbeams are integrally connected with extension plates, and the middle ends of the tops of the extension plates are provided with mounting grooves, and the insides of the mounting grooves are bonded with shock-absorbing rubber pads. Two groups of mounting holes are provided at the front and rear ends of the tops of the extension plates, and anti-collision buffer structures are fixedly installed on the left and right sides of the frame outer frame, and multiple groups of strip grooves are provided on the inner side of the frame outer frame, and the insides of the strip grooves are bonded with seismic isolation rubber strips. The utility model adopts the above structure, and when vibration occurs, the shock-absorbing rubber pad can absorb a certain amount of vibration to reduce the vibration amplitude. When vibration is generated from the bottom, the shock-absorbing sponge sheet can appropriately absorb the vibration to reduce the vibration amplitude, thereby achieving the purpose of shock-absorbing protection of the components inside the frame outer frame";

[0004] There are still certain disadvantages in use. Shock absorption through damping spring shock absorbers is only convenient for shock absorption and buffering of some minor impacts. When the impact force is large, the contraction stroke of the damper will quickly shrink to the limit, and the impact force will be directly transmitted to the frame assembly, which can easily cause the frame assembly to be deformed by the impact, and the buffering and energy absorption effect of the front and rear ends is poor. Utility Model Content

[0005] The purpose of the utility model is to provide a frame assembly with buffering and energy absorbing functions to solve the problems raised in the above background technology.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A frame assembly with a buffering and energy-absorbing function comprises a frame assembly, wherein surfaces at both ends of the frame assembly are provided with a plurality of mounting grooves, a buffer assembly is movably provided inside the mounting grooves, the buffer assembly comprises a mounting frame movably plugged into the mounting grooves, a top frame is slidably connected inside the mounting frame, a plurality of buffer plates are fixedly installed between the two side surfaces inside the mounting frame, protective assemblies are symmetrically and movably provided at both ends of the frame assembly, the protective assembly comprises an anti-collision beam, and a plurality of sliding rods are equidistantly and fixedly installed on one side surface of the anti-collision beam.

[0008] Furthermore, threaded holes are provided on both ends of the frame assembly on both sides of the mounting groove, connecting ears are symmetrically fixedly installed on both sides of the mounting frame, bolts are movably inserted inside the connecting ears, and one end of the bolt passes through the connecting ear and is screwed into the adjacent threaded hole.

[0009] Furthermore, a plurality of sliding holes are equidistantly formed on the surfaces of both ends of the frame assembly, and the sliding rods penetrate through adjacent sliding holes and are slidably connected with the sliding holes.

[0010] Furthermore, clamping plates are symmetrically fixedly installed on the surfaces of both ends of the installation frame, and the clamping plates are movably engaged with the frame assembly. Multiple limit plates that are slidably fitted with the installation frame are symmetrically fixedly installed on the surfaces of both sides of the installation frame.

[0011] Furthermore, sliding grooves are provided on both side surfaces of the top frame, and a limiting rod which slides through the sliding grooves is fixedly installed on the inner surface of the installation frame.

[0012] Furthermore, a connecting plate is fixedly installed on one end surface of the top frame and one side surface of the anti-collision beam, a spring is fixedly connected between two adjacent connecting plates, and a damper is fixedly connected inside the spring between two adjacent connecting plates.

[0013] Furthermore, a through groove is provided at the center of the surface of one end of the buffer plate, and grooves of different depths are symmetrically provided on the surfaces of both sides of a plurality of the buffer plates.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] 1. The spring and damper are contracted by the anti-collision beam. During the movement of the anti-collision beam, the elastic force of the spring and the resistance of the damper during contraction offset the impact force on the anti-collision beam, thereby reducing shock and buffering some smaller impacts through the spring and damper.

[0016] 2. When the impact force is large, the impact force is transferred to the top frame, and the top frame pushes the buffer plate in turn, so that the buffer plate is broken from the through groove and the groove by the impact, and folded to both sides. In the process of breaking and folding, the impact energy of the top frame is absorbed. When the buffer plate is bent to both sides of the top frame, the speed of movement of the top frame is slowed down again by friction. The closer the distance between the two grooves is to the top frame, the smaller the distance between the two grooves is, so the force required for the buffer plate to break gradually increases, thereby slowing down the speed of movement of the top frame through the rupture and deformation of the buffer plate, thereby improving the buffering energy absorption effect at the front and rear ends of the frame assembly.

[0017] 3. The card board is clamped at one end of the frame assembly, and the mounting frame is clamped inside the mounting groove. The bolts are passed through the connecting ears and screwed into the threaded holes to fix the mounting frame, so that the buffer component and the protective component are easy to install, and both are easy to disassemble and replace.

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] See also Figures 1 to 5 In an embodiment of the utility model, a frame assembly with a buffering and energy-absorbing function includes a frame assembly 1, a plurality of mounting grooves 101 are provided on both end surfaces of the frame assembly 1, a buffer assembly 2 is movably provided inside the mounting groove 101, the buffer assembly 2 includes a mounting frame 201 movably plugged into the mounting groove 101, a top frame 206 is slidably connected inside the mounting frame 201, a plurality of buffer plates 4 are fixedly installed between both side surfaces of the mounting frame 201, a protective assembly 3 is symmetrically and movably provided at both ends of the frame assembly 1, the protective assembly 3 includes an anti-collision beam 301, and a plurality of sliding rods 305 are equidistantly and fixedly installed on one side surface of the anti-collision beam 301.

[0026] Specifically, the protection component 3 prevents the frame assembly 1 from being directly hit, and then hits the buffer plate 4 through the buffer component 2 to absorb the impact energy that the protection component 3 cannot absorb, thereby buffering the anti-collision beam 301.

[0027] Embodiment 1

[0028] like Figure 4 As shown, in this embodiment, a connecting plate 302 is fixedly installed on one end surface of the top frame 206 and one side surface of the anti-collision beam 301, a spring 303 is fixedly connected between two adjacent connecting plates 302, and a damper 304 is fixedly connected inside the spring 303 between two adjacent connecting plates 302; a plurality of sliding holes 102 are equidistantly provided on the surfaces of both ends of the frame assembly 1, and the sliding rod 305 passes through the adjacent sliding holes 102 and is slidably connected to the sliding holes 102.

[0029] In this embodiment, when the anti-collision beam 301 is hit, the push spring 303 and the damper 304 contract, so that during the movement of the anti-collision beam 301, the impact force on the anti-collision beam 301 is offset by the elastic force of the spring 303 and the resistance of the damper 304 when it contracts, so that some smaller impacts are damped and buffered by the spring 303 and the damper 304.

[0030] like Figure 3-5As shown, in this embodiment, the surfaces of both ends of the installation frame 201 are symmetrically fixed with card plates 202, the card plates 202 are movably engaged with the frame assembly 1, and the surfaces of both sides of the installation frame 201 are symmetrically fixed with multiple limit plates 205 that slide and fit with the installation frame 201; both side surfaces of the top frame 206 are provided with sliding grooves 207, and the inner surface of the installation frame 201 is fixedly provided with a limit rod 208 that slides through the sliding grooves 207; a through groove 401 is provided at the center of the surface of one end of the buffer plate 4, and multiple side surfaces of the buffer plates 4 are symmetrically provided with grooves 402 of different depths.

[0031] In specific implementation, when the impact force is large, the contraction stroke of the damper 304 and the spring 303 is quickly reduced to the limit, so that the impact force is transferred to the top frame 206, and the top frame 206 pushes the buffer plate 4 in turn, so that the buffer plate 4 is hit and breaks from the through groove 401 and the groove 402, and folds to both sides. In the process of breaking and folding, the impact energy of the top frame 206 is absorbed. When the buffer plate 4 is bent to both sides of the top frame 206, the movement speed of the top frame 206 is slowed down again by friction. The closer the distance between the two grooves 402 is to the top frame 206, the smaller the distance between the two grooves 402 is, so that the force required for the buffer plate 4 to break gradually increases, thereby slowing down the movement speed of the top frame 206 through the rupture and deformation of the buffer plate 4, thereby improving the buffering and energy absorption effect of the front and rear ends of the frame assembly 1.

[0032] Embodiment 2

[0033] On the basis of the first embodiment, in order to make up for the problem that the buffer assembly 2 in the first embodiment is not convenient to disassemble and replace.

[0034] like Figure 4 As shown, in this embodiment, threaded holes 103 are provided on both ends of the surface of the frame assembly 1 located on both sides of the mounting groove 101, and connecting ears 203 are symmetrically fixedly installed on the two side surfaces of the mounting frame 201. Bolts 204 are movably inserted into the connecting ears 203, and one end of the bolt 204 passes through the connecting ears 203 and is screwed and connected with the adjacent threaded hole 103.

[0035] During specific implementation, the clamping plate 202 is clamped at one end of the frame assembly 1, and the mounting frame 201 is clamped inside the mounting groove 101. The bolt 204 passes through the connecting ear 203 and is screwed and fastened with the threaded hole 103 to fix the mounting frame 201, thereby facilitating the installation of the buffer component 2 and the protective component 3, and also facilitating the disassembly and replacement of both.

[0036] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
