Anti-torsion frame assembly

Abstract

The utility model relates to the technical field of frame assemblies, in particular to an anti-torsion frame assembly which comprises two parallel longitudinal beams, first air cushions are fixedly connected to the two ends of the opposite side faces of the two longitudinal beams, and a cross beam is fixedly connected between the two first air cushions at the opposite positions. A plurality of rectangular sleeves are fixedly arranged on the opposite side faces of the two longitudinal beams at equal intervals, and buffering mechanisms are fixedly connected to the two opposite sides of the two cross beams. According to the rear-end collision prevention device, when rear-end collision occurs, the collision plates at the corresponding positions drive the two sleeve rods at the corresponding positions to move backwards, the two sleeve rods moving backwards can press part of hydraulic oil in the sleeves at the corresponding positions into the other two sleeves through the guide pipes, and due to the fact that the hydraulic oil is sticky and low in flowing speed, the hydraulic oil can be separated from the sleeves at the corresponding positions. Therefore, impact force borne by the impact plate can be buffered and counteracted, and the cross beam and the two longitudinal beams at the corresponding positions can be prevented from deforming and twisting.

Description

Technical Field

[0001] The utility model relates to the technical field of vehicle frame assemblies, in particular to an anti-torsion vehicle frame assembly. Background Art

[0002] The frame is a framework structure that spans the front and rear axles of the car, commonly known as the beam. It is the base of the car and is generally composed of two longitudinal beams and several cross beams. It is supported on the wheels via 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. The function of the frame is to support and connect the various assemblies of the car, keep the assemblies in a relatively correct position, and withstand various loads inside and outside the car.

[0003] After searching, the Chinese patent number CN220281495U is a torsion-resistant frame assembly, including a frame body composed of two side beams and two cross beams, a stabilizing rod is fixedly installed between the two cross beams, and a first support rod and a second support rod are fixedly installed on the outer end surface of the stabilizing rod. The tripod composed of the first support rod and the second support rod can enhance the impact resistance of the side beams.

[0004] The above application can alleviate the impact force of the frame to a certain extent. Since the two measuring beams are still rigidly connected to the two cross beams, if the vehicle collides while driving (especially at high speed), the impact force received by the vehicle will be very large, so the possibility of torsional deformation of the frame is still very high. In addition, the vehicle may also be rear-ended during driving, which will also increase the possibility of torsional deformation of the frame. Utility Model Content

[0005] The purpose of the utility model is to provide an anti-torsion frame assembly 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 torsion-resistant frame assembly comprises two parallel longitudinal beams, both ends of opposite sides of the two longitudinal beams are fixedly connected with air cushions, a cross beam is fixedly connected between two air cushions at relative positions, a plurality of rectangular sleeves are fixedly provided at equal intervals on opposite sides of the two longitudinal beams, a buffer mechanism is fixedly connected on opposite sides of the two cross beams, the buffer mechanism comprises two symmetrically distributed sleeves fixed to the cross beams at corresponding positions, a sleeve rod is slidably connected inside the sleeve, hydraulic oil is filled between the sleeve rod and the sleeve at the corresponding position, and an impact plate is fixedly connected between the two sleeve rods at relative positions.

[0008] Furthermore, one end of the sleeve is fixedly connected with a connecting pipe which is communicated with the sleeve at the corresponding position and penetrates the beam at the corresponding position, a tee is fixedly connected between two connecting pipes at opposite positions, and a conduit is fixedly connected between the two tee pipes.

[0009] Furthermore, a connecting column is arranged between two rectangular sleeves at relative positions, both ends of the connecting column are fixedly connected to spring 1, and one end of the spring 1 is fixedly connected to air cushion 2 fixed to the rectangular sleeve at the corresponding position.

[0010] Furthermore, two symmetrical rotating seats are fixedly connected to the opposite side of the two longitudinal beams and between two adjacent connecting columns, two supporting plates that rotate with each other are rotatably connected between the two rotating seats at relative positions, and a second spring is fixedly connected between the two supporting plates at relative positions.

[0011] Preferably, the two supporting plates at opposite positions are in a V-shaped structure.

[0012] Furthermore, the side surfaces of the two longitudinal beams which are away from each other are fixedly connected with air bags.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. When a rear-end collision occurs, the impact plate at the corresponding position will drive the two sleeve rods at the corresponding position to move backward. The two sleeve rods moving backward can press part of the hydraulic oil in the sleeve at the corresponding position into the other two sleeves through the guide tube. Since the hydraulic oil is relatively viscous and flows slowly, it can buffer and offset the impact force on the impact plate, thereby preventing the crossbeam and two longitudinal beams at the corresponding position from deformation and twisting;

[0015] 2. When a side collision occurs on a vehicle, the airbag can buffer and offset part of the impact force, and then transmit the remaining impact force to the longitudinal beam at the corresponding position and compress the two air cushions at the corresponding position. At the same time, the spring one can be compressed and the two support plates at the relative position can be rotated relative to each other, and the spring two at the corresponding position can be compressed, so that the remaining impact force can be buffered and offset layer by layer, so that the impact force received by the two longitudinal beams and the two cross beams is not enough to cause them to deform and twist.

DETAILED DESCRIPTION

[0021] 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.

[0022] See also Figures 1 to 4 In an embodiment of the utility model, an anti-torsion frame assembly includes two parallel longitudinal beams 1, both ends of the opposite sides of the two longitudinal beams 1 are fixedly connected with air cushions 11, a cross beam 2 is fixedly connected between the two air cushions 11 at relative positions, a plurality of rectangular sleeves 12 are fixedly arranged at equal intervals on the opposite sides of the two longitudinal beams 1, and the two opposite sides of the two cross beams 2 are fixedly connected with a buffer mechanism 4, the buffer mechanism 4 includes two symmetrically distributed sleeves 41 fixed to the cross beams 2 at corresponding positions, a sleeve rod 42 is slidably connected inside the sleeve 41, hydraulic oil is filled between the sleeve rod 42 and the sleeve 41 at the corresponding position, and an impact plate 43 is fixedly connected between the two sleeve rods 42 at relative positions.

[0023] Specifically, the two longitudinal beams 1 and the two cross beams 2 are first fixed under the vehicle. When the vehicle rear-ends during driving, one of the impact plates 43 will first be subjected to the impact force and transmit the impact force to the two sleeve rods 42 at the corresponding position. Since hydraulic oil is filled between the sleeve rod 42 and the sleeve 41 at the corresponding position, the hydraulic oil can buffer the impact force received by the impact plate 43 at the corresponding position, thereby protecting the cross beam 2 at the corresponding position from deformation and twisting to a great extent. If the vehicle collides from the side during driving, since an air cushion 11 is fixed between the cross beam 2 and the two longitudinal beams 1, and the air cushion 11 is flexible, the impact force received by the longitudinal beam 1 is buffered by the action of the air cushion 11, thereby preventing the two longitudinal beams 1 from transmitting the impact force to each other, causing the two longitudinal beams 1 to deform and twist, and when a rear-end collision occurs, part of the impact force received by the cross beam 2 is buffered again by the action of the two air cushions 11 at the corresponding position, thereby achieving that the impact force transmitted by the cross beam 2 to the two longitudinal beams 1 will be very small, not enough to cause the two longitudinal beams 1 to twist and deform.

[0024] Embodiment 1

[0025] like Figure 4 As shown, in this embodiment, one end of the sleeve 41 is fixedly connected to a connecting pipe 44 that is connected to the sleeve 41 at the corresponding position and penetrates the beam 2 at the corresponding position, a three-way pipe 45 is fixedly connected between the two connecting pipes 44 at relative positions, and a conduit 46 is fixedly connected between the two three-way pipes 45.

[0026] In this embodiment, when a rear-end collision occurs, the impact plate 43 at the corresponding position will drive the two sleeve rods 42 at the corresponding position to move backward. The two sleeve rods 42 moving backward can press part of the hydraulic oil in the sleeve 41 at the corresponding position into the other two sleeves 41 through the conduit 46. Since the hydraulic oil is relatively viscous and flows slowly, the impact force exerted on the impact plate 43 can be buffered and offset, thereby preventing the cross beam 2 and the two longitudinal beams 1 at the corresponding position from deformation and twisting.

[0027] Embodiment 2

[0028] On the basis of the first embodiment, in order to further buffer the impact force received by the two longitudinal beams 1 and the two cross beams 2 .

[0029] like Figure 2 and Figure 4As shown, in the present embodiment, a connecting column 3 is provided between two rectangular sleeves 12 at relative positions, springs 1 31 are fixedly connected at both ends of the connecting column 3, and air cushion 2 32 fixed to the rectangular sleeve 12 at the corresponding position is fixedly connected at one end of the spring 1 31, two symmetrical rotating seats 13 are fixedly connected to the opposite side of the two longitudinal beams 1 and between two adjacent connecting columns 3, two supporting plates 5 that rotate with each other are rotatably connected between the two rotating seats 13 at relative positions, springs 2 51 are fixedly connected between the two supporting plates 5 at relative positions, the two supporting plates 5 at relative positions are in a V-shaped structure, and airbags 14 are fixedly connected to the opposite side of the two longitudinal beams 1.

[0030] In this embodiment, when a side collision occurs on the vehicle, the airbag 14 can buffer and offset a part of the impact force, and then the remaining impact force is transmitted to the longitudinal beam 1 at the corresponding position and compresses the two air cushions 11 at the corresponding position, and at the same time, the spring 1 31 can be compressed and the two support plates 5 at the relative position can be rotated relative to each other, and the spring 2 51 at the corresponding position can be compressed, so that the remaining impact force can be buffered and offset layer by layer, so that the impact force on the two longitudinal beams 1 and the two cross beams 2 is not enough to cause them to deform and twist.

[0031] 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.
