Description

Technical Field

[0001] The present application relates to the field of automobile technology, and in particular to a rear shock absorber mounting assembly and a vehicle. Background Art

[0002] When a car is driving, the road conditions on some roads are poor. In off-road conditions, the amplitude and frequency of the road load spectrum vary greatly and are very unstable, which puts higher requirements on the force transmission structure of the rear shock absorber of the car frame.

There are problems such as insufficient connection stiffness and failure and cracking of welding points between the rear shock absorber and the frame.

[0004] Especially in extreme off-road conditions, the instantaneous impact is large. In addition to the spring and damping of the shock absorber itself absorbing part of the load, the traditional rear shock absorber seat structure is difficult to absorb the load, which in turn leads to problems with the static strength or fatigue strength of the vehicle body in the rear shock absorber seat area, making the traditional automobile frame rear shock absorber seat unable to be used in extreme off-road conditions.

DETAILED DESCRIPTION

Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0042] The directional nouns involved in the embodiments of the present application, such as "upper", "lower", "side", etc., are generally based on the relative relationship of the directions shown in the figures, and these directional nouns are used only to more clearly describe the relationship between structures, and are not intended to describe absolute directions. When the product is placed in different postures, the direction may change, for example, "upper" and "lower" may be interchangeable.

[0043] Unless otherwise defined, all technical terms used in the embodiments of the present application have the same meanings as commonly understood by those of ordinary skill in the art.

[0044] In order to make the technical solutions and advantages of the present application more clear, the implementation methods of the present application will be further described in detail below with reference to the accompanying drawings.

[0045] When a car is driving, the road conditions on some roads are poor. In off-road conditions, the amplitude and frequency of the road load spectrum vary greatly and are very unstable, which puts higher requirements on the force transmission structure of the rear shock absorber of the car frame.

[0046] At present, the traditional non-load-bearing frame is generally formed by two longitudinal beams and multiple cross beams connected between the two longitudinal beams. The rear shock absorber of the frame is directly welded to the frame longitudinal beam through the rear shock absorber seat. The rear shock absorber seat is cantilevered on one side of the frame longitudinal beam. There are problems such as insufficient connection stiffness and failure and cracking of welding points between the rear shock absorber and the frame.

[0047] Especially in extreme off-road conditions, the instantaneous impact is large. In addition to the spring and damping of the shock absorber itself absorbing part of the load, the traditional rear shock absorber seat structure is difficult to absorb the load, which in turn leads to problems with the static strength or fatigue strength of the vehicle body in the rear shock absorber seat area, making the traditional automobile frame rear shock absorber seat unable to be used in extreme off-road conditions.

[0048] In view of the above technical problems, the present application provides a rear shock absorber mounting assembly 1, which can improve the structural strength and rigidity of the rear shock absorber seat 15.

[0049] like Figure 1 As shown, the rear shock absorber mount 15 includes a first longitudinal beam 13 , a second longitudinal beam 14 , a first cross beam 11 , a second cross beam 12 and two rear shock absorber mounts 15 .

[0050] The first longitudinal beam 13 and the second longitudinal beam 14 are spaced apart, and the first transverse beam 11 and the second transverse beam 12 are spaced apart. For example, the first longitudinal beam 13 and the second longitudinal beam 14 are spaced apart from each other along a first direction, and the first transverse beam 11 and the second transverse beam 12 are spaced apart from each other along a second direction, and the first direction and the second direction are perpendicular to each other.

[0051] Optionally, the first longitudinal beam 13 and the second longitudinal beam 14 are manufactured by an internal high pressure forming process, and the material thickness is 3 mm.

[0052] Internal high pressure forming is also called hydraulic forming or hydraulic forming. It is a material forming process that uses liquid as a forming medium and controls the internal pressure and material flow to achieve the purpose of forming hollow parts. By adopting the internal high pressure forming process to make the first longitudinal beam 13 and the second longitudinal beam 14, not only the forming speed is fast, the production cycle is reduced, and the production efficiency is improved, but also the advantages of high strength, high rigidity, light weight, and no welds are obtained.

[0053] Exemplarily, the first cross beam 11 and the second cross beam 12 are round tube beams, which can increase the bending and torsional strength of the rear shock absorber mounting assembly 1 .

[0054] Both ends of the first cross beam 11 and the second cross beam 12 are connected to the first longitudinal beam 13 and the second longitudinal beam 14 respectively. At least one end of the first cross beam 11 extends outward through the first longitudinal beam 13 or the second longitudinal beam 14 to form at least one first protrusion 111. At least one end of the second cross beam 12 extends outward through the first longitudinal beam 13 or the second longitudinal beam 14 to form at least one second protrusion 121.

[0055] For example Figure 1 As shown, one end of the first cross beam 11 and one end of the second cross beam 12 both protrude relative to the first longitudinal beam 13, forming a first protrusion 111 and a second protrusion 121 on the side of the first longitudinal beam 13 away from the second longitudinal beam 14. Further, the other end of the first cross beam 11 and the other end of the second cross beam 12 both protrude relative to the second longitudinal beam 14, forming a first protrusion 111 and a second protrusion 121 on the side of the second longitudinal beam 14 away from the first longitudinal beam 13, that is, the rear shock absorber mounting assembly 1 includes two first protrusions 111 and two second protrusions 121.

[0056] Specifically, the first longitudinal beam 13 and the second longitudinal beam 14 are both provided with welding holes, and the first cross beam 11 and the second cross beam 12 pass through the welding holes, thereby being welded to the first longitudinal beam 13 and the second longitudinal beam 14. Exemplarily, the first cross beam 11 and the second cross beam 12 are connected to the first longitudinal beam 13 and the second longitudinal beam 14 by welding.

[0057] Two rear shock absorber seats 15 are respectively mounted on the first longitudinal beam 13 and the second longitudinal beam 14 . Two ends of at least one rear shock absorber seat 15 are respectively overlapped on the first protrusion 111 and the second protrusion 121 . The rear shock absorber seat 15 is provided with a rear shock absorber mounting portion 151 .

[0058] For example, Figure 1 As shown, one of the rear shock absorber seats 15 is installed on the side of the first longitudinal beam 13 away from the second longitudinal beam 14, and the two ends of the rear shock absorber seat 15 in the length direction are respectively connected to the top of the first protrusion 111 and the top of the second protrusion 121; the other rear shock absorber seat 15 is installed on the side of the second longitudinal beam 14 away from the first longitudinal beam 13, and optionally, the two ends of the rear shock absorber seat 15 in the length direction are respectively connected to the top of the first protrusion 111 and the top of the second protrusion 121.

[0059] Exemplarily, the first protrusion 111 extends outwardly by about 100 mm relative to the first longitudinal beam 13 or the second longitudinal beam 14 , and the second protrusion 121 extends outwardly by about 100 mm relative to the first longitudinal beam 13 or the second longitudinal beam 14 , ensuring sufficient support for the rear shock absorber seat 15 .

[0060] Exemplarily, the rear shock absorber seat 15 is connected to the first longitudinal beam 13 / the second longitudinal beam 14 , the first protruding portion 111 and the second protruding portion 121 by welding or other welding methods.

[0061] Exemplarily, the rear shock absorber mounting portion 151 is located at the bottom of the rear shock absorber seat 15, and the rear shock absorber mounting portion 151 is located between the first protrusion 111 and the second protrusion 121, and the top end of the rear shock absorber 100 is installed in the rear shock absorber mounting portion 151. When the rear shock absorber 100 is impacted, the impact load is transmitted to the first protrusion 111, the second protrusion 121 and the first longitudinal beam 13 / the second longitudinal beam 14 on both sides through the rear shock absorber mounting portion 151, thereby effectively dispersing the impact load and preventing the rear shock absorber seat 15 from being damaged due to a large instantaneous impact.

[0062] The rear shock absorber mounting assembly 1 provided in the embodiment of the present application has a rear shock absorber seat 15 mounted on the first longitudinal beam 13 or the second longitudinal beam 14, and the two ends of the rear shock absorber seat 15 are overlapped on the first protrusion 111 and the second protrusion 121 respectively, and the rear shock absorber seat 15 is simultaneously connected to the first longitudinal beam 13 / the second longitudinal beam 14, the first cross beam 11 and the second cross beam 12. Therefore, the rear shock absorber seat 15 is supported on three sides to form a stable force triangle, and the force point is inside the triangle, so that the rear shock absorber seat 15 can transfer the load it bears to the first longitudinal beam 13 / the second longitudinal beam 14, the first cross beam 11 and the second cross beam 12, which greatly improves the structural strength and bearing capacity of the rear shock absorber seat 15, avoids local stress concentration causing welding point failure and cracking, and enables the rear shock absorber mounting assembly 1 to be used in extreme off-road conditions, solving the technical problem that the cantilever of the rear shock absorber seat of the traditional frame is too long and has no support.

[0063] In a further embodiment, on the side of the first longitudinal beam 13 facing away from the second longitudinal beam 14, the portion of the first longitudinal beam 13 for mounting the rear shock absorber seat 15 is recessed in the direction pointing to the second longitudinal beam 14; on the side of the second longitudinal beam 14 facing away from the first longitudinal beam 13, the portion of the second longitudinal beam 14 for mounting the rear shock absorber seat 15 is recessed in the direction pointing to the first longitudinal beam 13.

[0064] Specifically, a portion of the first longitudinal beam 13 on a side away from the second longitudinal beam 14 is recessed inwardly, and a portion of the second longitudinal beam 14 on a side away from the first longitudinal beam 13 is recessed inwardly. Figure 2 As shown, in the top view of the rear shock absorber mounting assembly 1 , the connection between the rear shock absorber seat 15 and the first longitudinal beam 13 is closer to the inner side of the first longitudinal beam 13 than the outer edge of the first longitudinal beam 13 .

[0065] This arrangement provides ample installation space for the rear suspension of the vehicle. At the same time, the connection between the rear shock absorber seat 15 and the first longitudinal beam 13 or the second longitudinal beam 14 is arc-shaped, thereby increasing the contact area between the rear shock absorber seat 15 and the first longitudinal beam 13 or the second longitudinal beam 14. While meeting the assembly requirements, it is also beneficial to improve the load-bearing capacity of the rear shock absorber seat 15.

[0066] Furthermore, the rear shock absorber seat 15 is a bowl-shaped structure, and the rear shock absorber mounting portion 151 is located in the recess of the rear shock absorber seat 15 .

[0067] like Figure 1 As shown, the rear shock absorber seat 15 is roughly an inverted bowl-like structure, or in other words, the rear shock absorber 100 is roughly arched, and the rear shock absorber mounting portion 151 is located in the concave part in the middle of the rear shock absorber seat 15.

[0068] Through this arrangement, the bowl-shaped structure of the rear shock absorber seat 15 can be utilized to evenly disperse the impact force at the rear shock absorber mounting portion 151, reducing the pressure on the rear shock absorber mounting portion 151, thereby reducing damage to the rear shock absorber seat 15 itself and improving the impact resistance and structural strength of the rear shock absorber seat 15.

[0069] Furthermore, the rear shock absorber seat 15 is provided with a reinforcing plate 152 , and the reinforcing plate 152 is mounted on a side of the rear shock absorber seat 15 away from the rear shock absorber mounting portion 151 .

[0070] like Figure 1 As shown, the reinforcing plate 152 is plate-shaped and is disposed on the top of the rear shock absorber seat 15. Exemplarily, the thickness of the reinforcing plate 152 is 4 mm.

[0071] By providing a reinforcing plate 152 on the side of the rear shock absorber seat 15 away from the rear shock absorber mounting portion 151, the strength of the rear shock absorber seat 15 at the stress point is greatly enhanced, and the structural strength and rigidity of the rear shock absorber seat 15 are further improved, ensuring that the rear shock absorber seat 15 meets the use requirements in off-road conditions.

[0072] In one embodiment, each rear shock absorber seat 15 also has two mounting plates 153, which are located on opposite sides of the rear shock absorber mounting portion 151. The mounting plates 153 include a connected main body portion 1532 and a flange portion 1533. The main body portion 1532 is connected to the inner wall of the rear shock absorber seat 15, and the flange portion 1533 is connected to the first protrusion 111 or the second protrusion 121. The main body portion 1532 is provided with a connecting hole 1531.

[0073] Exemplarily, the two mounting plates 153 are arranged opposite to each other along the length direction of the rear shock absorber seat 15, and the connecting hole 1531 is a through hole for connecting with threaded fasteners such as bolts, so as to realize the connection between the rear shock absorber 100 and the rear shock absorber seat 15. Optionally, the connecting hole 1531 is provided with an internal thread.

[0074] Specifically, Figure 5As shown, there is a certain angle between the main body 1532 and the flange 1533, so that the mounting plate 153 is roughly "L" shaped. The main body 1532 extends roughly along the length direction of the rear shock absorber seat 15, and the main body 1532 covers the inner wall of the rear shock absorber seat 15. The flange 1533 extends roughly along the height direction of the rear shock absorber seat 15, and the flange 1533 is connected to the first protruding portion 111 or the second protruding portion 121.

[0075] Optionally, the material thickness of the mounting plate 152 is 3 mm.

[0076] By providing the mounting plate 153 and the connecting hole 1531, a bolt fastener installation position is provided for the connection between the rear shock absorber seat 15 and the rear shock absorber 100, which facilitates the installation of the rear shock absorber 100 and helps to improve the connection strength between the rear shock absorber 100 and the rear shock absorber seat 15, and prevents relative slippage or misalignment between the rear shock absorber 100 and the rear shock absorber seat 15.

[0077] The rear shock absorber mounting assembly 1 further includes a plurality of brackets 16 and a plurality of buffers 17. The brackets 16 are disposed on a side of the first protrusion 111 or the second protrusion 121 away from the rear shock absorber mounting portion 151. The buffers 17 are mounted on the brackets 16. The buffers 17 are flexible members having elastic deformation capability.

[0078] Exemplarily, the first beam 11 and the second beam 12 are hollow structures with a notch at the bottom, and the bracket 16 is welded to the notch. Alternatively, the bracket 16 is integrally formed with the first beam 11 / the second beam 12, and the bracket 16 is a part of the first beam 11 or the second beam 12.

[0079] The buffer member 17 is made of a flexible material with elastic deformation capability such as rubber. Figure 4 As shown, the buffer member 17 is installed at the bottom of the bracket 16.

[0080] Specifically, Figure 4 As shown, the upper control arm 200 of the suspension of the vehicle body is located below the rear shock absorber seat 15, and the buffer 17 and the bracket 16 can provide a buffering effect when the vehicle passes through off-road conditions. When the instantaneous impact is large, the buffer 17 directly contacts the upper control arm 200 of the suspension to form a soft connection, thereby reducing the impact on the rear shock absorber seat 15 and preventing the rear shock absorber seat 15 from being damaged.

[0081] The distance between the buffer 17 and the upper control arm 200 of the suspension can be set according to actual needs to ensure that the buffer 17 is released from the upper control arm 200 of the suspension before the rear shock absorber 100 reaches the load limit, thereby achieving the purpose of dispersing the impact load.

[0082] In a specific embodiment, the bracket 16 is provided with a threaded hole 161 , and the buffer member 17 is provided with a threaded fastener, which is matched and connected with the threaded hole 161 .

[0083] Specifically, a threaded fastener is embedded in the buffer 17 , and the threaded fastener is screwed into the threaded hole 161 , and then a nut is inserted to fix it, thereby achieving a threaded connection between the buffer 17 and the bracket 16 , ensuring that the buffer 17 and the bracket 16 are firmly connected.

[0084] In one embodiment, the rear shock absorber mounting assembly 1 further includes a reinforcement portion 18 , a first end of the reinforcement portion 18 is connected to the first cross beam 11 or the second cross beam 12 , and a second end of the reinforcement portion 18 is connected to the first longitudinal beam 13 or the second longitudinal beam 14 .

[0085] The number of reinforcing parts 18 is multiple. For example, there are two reinforcing parts 18, such as Figure 3 As shown, one of the reinforcing parts 18 is in the shape of a rod and is obliquely placed between the first cross beam 11 and the first longitudinal beam 13, and the first end is connected to the first cross beam 11, and the second end is connected to the first longitudinal beam 13; another reinforcing part 18 is in the shape of a rod and is obliquely placed between the first cross beam 11 and the second longitudinal beam 14, and the first end is connected to the first cross beam 11, and the second end is connected to the second longitudinal beam 14. Alternatively, there are four reinforcing parts 18, two of which are arranged between the first cross beam 11 and the first longitudinal beam 13 / the second longitudinal beam 14, and the other two are arranged between the second cross beam 12 and the first longitudinal beam 13 / the second longitudinal beam 14.

[0086] By providing the reinforcing portion 18, oblique support is provided for the first cross beam 11 / the second cross beam 12 and the first longitudinal beam 13 / the second longitudinal beam 14, thereby improving the connection strength between the cross beam and the longitudinal beam and preventing relative shaking or connection failure between the cross beam and the longitudinal beam.

[0087] In a further embodiment, the second cross beam 12 includes a first sub-cross beam 122 and a second sub-cross beam 123 that are oppositely disposed, and the distance between the first sub-cross beam 122 and the second sub-cross beam 123 is less than or equal to the distance between the first longitudinal beam 13 and the second longitudinal beam 14 .

[0088] In this embodiment, at least a portion of the second cross beam 12 located between the first longitudinal beam 13 and the second longitudinal beam 14 is removed to form a first sub-cross beam 122 and a second sub-cross beam 123 that are relatively arranged, and the distance between the first sub-cross beam 122 and the second sub-cross beam 123 is less than or equal to the distance between the first longitudinal beam 13 and the second longitudinal beam 14.

[0089] Through this arrangement, the weight of the rear shock absorber mounting assembly 1 is reduced, which is conducive to achieving a lightweight design of the rear shock absorber mounting assembly 1.

[0090] The present application also provides a vehicle, such as Figure 4 As shown, the vehicle includes a rear shock absorber 100 and a rear shock absorber mounting assembly 1 provided by any one of the above embodiments, and the rear shock absorber 100 is mounted on a rear shock absorber mounting portion 151 .

[0091] Exemplarily, the vehicle is a vehicle with a non-load-bearing body, such as a truck, a bus, an off-road vehicle, a jeep, a car, or the like.
