Description

Technical Field

[0001] The utility model relates to the technical field of vehicles, in particular to a subframe mounting structure and a vehicle having the same. Background Art

[0002] When a collision accident occurs during high-speed driving of a vehicle, the front subframe will cause great impact damage to the occupant compartment under the action of impact force. For example, the front subframe may intrude into the occupant compartment, thus causing great harm to the driver and passengers. Therefore, in the related art, a structural design is adopted in which the front subframe can fall off from the subframe mounting structure, so that the subframe can be separated from the vehicle body in time during a high-speed collision, thereby reducing the degree of damage to the occupant compartment during the vehicle collision and reducing the injury of the driver and passengers.

[0003] However, in the related art, the front subframe usually weakens the structure at the connection structure to meet the requirement of the front subframe falling off. The weakening of the connection structure results in insufficient dynamic stiffness of the front subframe at the connection structure, making it easy to generate abnormal noises at the weakening position of the connection structure during the daily use of the vehicle, thereby reducing the NVH (Noise, Vibration, Harshness) performance of the vehicle and the driving experience of the driver and passengers.

[0033] Embodiments of the present utility model will be described in detail below. Examples of the embodiments are shown in the drawings, where the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the drawings are exemplary and are intended to explain the present utility model and should not be construed as limiting the present utility model.

[0034] Reference will be made below to Figures 1 - 6 describe the subframe mounting structure 100 according to an embodiment of the first aspect of the present utility model.

[0035] As Figures 1 - 6 shown, the subframe mounting structure 100 according to an embodiment of the first aspect of the present utility model includes: a longitudinal beam 10, a vertical partition 20, a knuckle mounting plate 40, a subframe knuckle 50 and a connecting sleeve 51, a fixed sleeve 30 and a connecting member 60.

[0036] Specifically, the vertical partition 20 is provided on the longitudinal beam 10; the knuckle mounting plate 40 is provided on the lower side of the longitudinal beam 10 (the lower side in the up-down direction as shown in Figure 1 the figure) and is connected to the longitudinal beam 10. The knuckle mounting plate 40 is provided with a mounting portion having a through hole 401; the connecting sleeve 51 is provided on the subframe knuckle 50 and is located on the lower side of the mounting portion; the fixed sleeve 30 extends in the vertical direction (the up-down direction as shown in Figure 1 the figure), the fixed sleeve 30 is fixed to the mounting portion and is located on the upper side of the mounting portion. The fixed sleeve 30 is connected to the vertical partition 20 and is provided on the front side of the vertical partition 20 (the front side in the front-back direction as shown in Figure 1 the figure); the connecting member 60 passes through the connecting sleeve 51, the through hole 401 and the fixed sleeve 30 to fixedly connect the connecting sleeve 51 and the fixed sleeve 30.

[0037] In this embodiment, the fixed sleeve 30 extends in the vertical direction, the fixed sleeve 30 is fixed on the knuckle mounting plate 40 and is arranged on the upper side of the mounting portion. Specifically, the fixed sleeve 30 may communicate with the through hole 401 of the mounting portion. The fixed sleeve 30 may be fixed to the lower side of the longitudinal beam 10 together with the knuckle mounting plate 40. The fixed sleeve 30 is fixedly connected to the vertical partition 20 on the longitudinal beam 10. Then, the fixed sleeve 30 is connected to the knuckle mounting plate 40 and the vertical partition 20 in sequence from bottom to top in the vertical direction.

[0038] The connecting sleeve 51 of the subframe knuckle 50 is arranged on the lower side of the mounting portion. The connecting sleeve 51 can be arranged vertically opposite to the fixed sleeve 30 and the through hole 401. The connecting member 60 can sequentially pass through the connecting sleeve 51 and the through hole 401 from bottom to top and penetrate into the fixed sleeve 30, so that the connecting sleeve 51 and the fixed sleeve 30 are fixedly connected through the connecting member 60, thereby enabling the subframe knuckle 50 to be fixed on the longitudinal beam 10. Exemplarily, a plurality of subframe knuckles 50 can be arranged circumferentially on the subframe. Structures such as the vertical partition 20, the knuckle mounting plate 40, and the fixed sleeve 30 in this embodiment can be correspondingly arranged so that the subframe knuckle 50 can be stably fixed on the longitudinal beam 10, and the subframe is a front subframe.

[0039] When a collision accident occurs during the high-speed driving of the vehicle, the subframe moves backward as a whole under the action of the impact force. Specifically, at the connecting sleeve 51, the connecting sleeve 51 moves backward under the action of the impact force, causing the part of the connecting member 60 that cooperates with the connecting sleeve 51 to move backward. Since the connecting member 60 vertically passes through the through hole 401 of the knuckle mounting plate 40 and is fixedly connected to the fixed sleeve 30, the knuckle mounting plate 40 plays a supporting role on the connecting member 60 at the through hole 401, causing the connecting member 60 to rotate around the through hole 401. The part of the connecting member 60 that cooperates with the connecting sleeve 51 rotates backward around the through hole 401 under the backward acting force of the connecting sleeve 51, thereby causing the part of the connecting member 60 that cooperates with the fixed sleeve 30 to rotate forward around the through hole 401, and further causing the connecting member 60 to drive the fixed sleeve 30 to rotate forward.

[0040] When the connecting member 60 drives the fixed sleeve 30 to rotate forward, since the fixed sleeve 30 is sequentially connected to the knuckle mounting plate 40 and the vertical partition 20 from bottom to top, the fixed sleeve 30 can rotate forward relatively stably around the part where it is connected to the knuckle mounting plate 40, thereby forming a separating force in the front-rear direction between the fixed sleeve 30 and the vertical partition 20. In this embodiment, the fixed sleeve 30 is arranged on the front side of the vertical partition 20, which can well prevent the vertical partition 20 from hindering the rotation of the fixed sleeve 30 when the fixed sleeve 30 rotates forward, so that the fixed sleeve 30 can be stably, reliably and easily separated from the vertical partition 20 under the action of the impact force generated during the high-speed collision of the vehicle.

[0041] At the same time, when a collision accident occurs during the high-speed driving of the vehicle, the longitudinal beam 10 will be bent laterally (such as the left-right direction shown) under the action of the impact force. The longitudinal beam 10 moves backward and laterally, causing the vertical partition 20 fixed on the longitudinal beam 10 to move laterally following the movement of the longitudinal beam 10, so that the moving directions of the fixed sleeve 30 and the vertical partition 20 are different. The different moving directions cause the connection at the connection part between the fixed sleeve 30 and the vertical partition 20 to be greatly pulled and damaged, so that the fixed sleeve 30 and the vertical partition 20 can be better separated. Figure 1 As shown, the longitudinal beam 10 bends laterally, the longitudinal beam 10 moves backward and laterally, causing the vertical partition 20 fixed on the longitudinal beam 10 to move laterally following the movement of the longitudinal beam 10, so that the moving directions of the fixed sleeve 30 and the vertical partition 20 are different. The different moving directions cause the connection at the connection part between the fixed sleeve 30 and the vertical partition 20 to be greatly pulled and damaged, so that the fixed sleeve 30 and the vertical partition 20 can be better separated.

[0042] After the fixed sleeve 30 is disengaged from the vertical partition plate 20, the whole of the horn mounting plate 40 and the fixed sleeve 30 can be stably and reliably separated from the longitudinal beam 10 under the gravity and impact force of the subframe horn 50, so that the subframe horn 50 falls off from the subframe mounting structure 100.

[0043] In this embodiment, by arranging the fixed sleeve 30 on the front side of the vertical partition plate 20, the fixed sleeve 30 can rotate forward more stably, reliably and easily under the action of the impact force to disengage from the vertical partition plate 20, so that the fixed sleeve 30 and the horn mounting plate 40 can fall off integrally with the subframe horn 50, well meeting the requirement of subframe falling off. Thus, it is possible to avoid performing structural weakening treatment on the connecting sleeve 51 and the fixed sleeve 30. For example, it is possible to well avoid grooving at the connecting sleeve 51 to meet the requirement of the subframe horn 50 falling off. As a result, the overall structure of structures such as the connecting sleeve 51, the connecting member 60 and the fixed sleeve 30 can maintain good dynamic stiffness after assembly, so that the subframe mounting structure 100 has good NVH performance and provides a better experience for the driver and passengers during the daily use of the vehicle.

[0044] For the subframe mounting structure 100 according to the embodiment of the present invention, by arranging the longitudinal beam 10 and the vertical partition plate 20, the subframe horn 50 is connected to the fixed sleeve 30 through the connecting sleeve 51 and the connecting member 60, and the fixed sleeve 30 is fixed to the longitudinal beam 10 through the horn mounting plate 40 and the vertical partition plate 20. The fixed sleeve 30 is arranged on the front side of the vertical partition plate 20, so that while meeting the requirement of the subframe horn 50 falling off, the subframe mounting structure 100 can avoid setting weakening structures in the connecting sleeve 51, thereby greatly reducing the probability of abnormal noise in the vehicle and providing a better use experience for the driver and passengers.

[0045] In some embodiments of the present invention, as Figure 2 and Figure 3 shown, the vertical partition plate 20 may be provided with a first welding hole 201, and the vertical partition plate 20 and the fixed sleeve 30 are welded and connected at the first welding hole 201.

[0046] In this embodiment, by arranging the first welding hole 201 on the vertical partition plate 20, the structure is simple, which is convenient for the welding operation between the vertical partition plate 20 and the fixed sleeve 30, and makes the assembly and fixation of the vertical partition plate 20 and the fixed sleeve 30 more convenient. The vertical partition plate 20 and the fixed sleeve 30 are welded and connected at the first welding hole 201, which can, to a certain extent, make the connection and fixation area between the fixed sleeve 30 and the vertical partition plate 20 smaller. Thus, when a collision accident occurs during the high-speed driving of the vehicle, the fixed sleeve 30 can be more easily disengaged from the vertical partition plate 20 under the action of the impact force and the tensile force of the lateral movement of the longitudinal beam 10, so that the subframe horn 50 can fall off more stably and reliably.

[0047] In some embodiments of the present utility model, the connecting member 60 may be a fastening bolt, the inner wall surface of the fixed sleeve 30 is a threaded surface, and the connecting member 60 passes through the connecting sleeve 51 and is threadedly connected to the fixed sleeve 30.

[0048] In this embodiment, the connecting member 60 is set as a fastening bolt, and the fixed sleeve 30 is provided with internal threads. The structure is simple and the assembly is convenient. The fastening bolt has good structural strength, making the connection between the connecting sleeve 51 and the fixed sleeve 30 more stable and reliable, so that the subframe knuckle 50 can be stably and reliably fixed on the longitudinal beam 10.

[0049] In some embodiments of the present utility model, as Figure 3 and Figure 4 shown, the knuckle mounting plate 40 may partially bulge downward to form a mounting boss 41, and the mounting portion is formed on the mounting boss 41.

[0050] In this embodiment, the knuckle mounting plate 40 is formed with a mounting boss 41. The mounting boss 41 bulges downward, and the mounting portion is formed on the mounting boss 41. Specifically, a through hole 401 may be formed on the mounting boss 41, and the fixed sleeve 30 is located in a groove formed on the upward side of the mounting boss 41. The knuckle mounting plate 40 is provided with the mounting boss 41 and the mounting boss 41 bulges downward, with a simple structure, making the overall structural strength of the knuckle mounting plate 40 higher, so that the knuckle mounting plate 40 can better cooperate with the fixed sleeve 30 to assemble and fix the subframe knuckle 50.

[0051] During the assembly of the subframe mounting structure 100, the connecting sleeve 51 of the subframe knuckle 50 is arranged on the lower side of the knuckle mounting plate 40. After the connecting sleeve 51 is assembled and fixed to the fixed sleeve 30 on the knuckle mounting plate 40 through the connecting member 60, the upper end face of the connecting sleeve 51 abuts and fixes against the lower convex surface of the mounting boss 41, so that the subframe knuckle 50 is fixed at a certain height position in the subframe mounting structure 100. Setting the mounting boss 41 in this embodiment can well meet the assembly requirements of the subframe knuckle 50 in the subframe mounting structure 100.

[0052] It can be understood that in different vehicles, there are differences in the layout height of the longitudinal beam 10 in the subframe mounting structure 100. In this embodiment, the knuckle mounting plate 40 is provided and the knuckle mounting plate 40 is provided with a downwardly protruding mounting boss 41. During the production and processing of the knuckle mounting plate 40, the knuckle mounting plate 40 can adjust the size of the downward protrusion of the mounting boss 41 according to the layout of the longitudinal beam 10, so as to meet the assembly requirements of the subframe knuckle 50 of different vehicles and can better meet the needs of platform design.

[0053] In an embodiment of the present utility model, as Figure 3 andFigure 4 As shown, the horn mounting plate 40 may be provided with a first flange 42 , which extends vertically upward and is welded and fixed to the longitudinal beam 10 .

[0054] In this embodiment, a first flange 42 is provided on the horn mounting plate 40, and the first flange 42 is welded and fixed to the longitudinal beam 10. The structure is simple, and the horn mounting plate 40 can be more securely installed and fixed on the longitudinal beam 10, so that the sub-frame horn 50 can be more stably and reliably fixed on the longitudinal beam 10, so that the overall structural stability of the sub-frame mounting structure 100 is better.

[0055] In some embodiments of the present invention, reference Figure 1 As shown, the longitudinal beam 10 may have an installation cavity 101 , the vertical partition 20 is arranged in the installation cavity 101 , the longitudinal beam 10 is provided with a through hole, and the fixing sleeve 30 is suitable for passing through the through hole to be connected with the vertical partition 20 .

[0056] In this embodiment, the longitudinal beam 10 is provided with an installation cavity 101, and the vertical partition 20 is arranged in the installation cavity 101. The structure is simple, making the overall structure of the vertical partition 20 and the longitudinal beam 10 more compact. The longitudinal beam 10 is provided with a through hole, and the fixing sleeve 30 passes through the through hole and is connected to the vertical partition 20. The structure is simple and can well meet the assembly requirements of the fixing sleeve 30, the longitudinal beam 10 and the vertical partition 20.

[0057] In one embodiment of the present invention, Figure 2 and Figure 3 As shown, the vertical partition 20 may be provided with a plurality of second flanges 21 , which are arranged at intervals along the circumference of the vertical partition 20 , and the second flanges 21 are welded to the inner wall of the installation cavity 101 .

[0058] In this embodiment, multiple second flanges 21 are arranged at intervals in the circumferential direction of the vertical partition 20, and the multiple second flanges 21 are welded to the inner wall of the installation cavity 101, which has a simple structure, making the connection and fixation between the vertical partition 20 and the longitudinal beam 10 more convenient and reliable, so that the vertical partition 20 can stably and reliably follow the lateral deviation of the longitudinal beam 10 when a collision accident occurs during high-speed driving of the vehicle, so that the fixing sleeve 30 and the vertical partition 20 can be separated more stably under the pulling force of the longitudinal beam 10. For example, the second flanges 21 can be provided with two, three, four, five, etc., and the number of the second flanges 21 can be reasonably set according to the connection and fixation needs.

[0059] In one embodiment of the present invention, Figure 2 As shown, the longitudinal beam 10 may include: an outer plate 11 and an inner plate 12 , and the outer plate 11 and the inner plate 12 cooperate to define a mounting cavity 101 .

[0060] In this embodiment, the longitudinal beam 10 is provided with an outer plate 11 and an inner plate 12, and the outer plate 11 and the inner plate 12 cooperate to define a mounting cavity 101, which has a simple structure and is convenient for assembling and fixing the longitudinal beam 10 and the vertical partition 20.

[0066] In some embodiments of the present invention, the vertical partition 20 may be a sheet metal part, and the fixing sleeve 30 may be a casting part.

[0067] In this embodiment, the vertical partition 20 is configured as a sheet metal part and the fixing sleeve 30 is configured as a casting part. The structure is simple, can well meet the use requirements of the vertical partition 20 and the fixing sleeve 30, and is easy to assemble.

[0068] Reference below Figures 1 - 6 A vehicle according to an embodiment of the second aspect of the utility model is described.

[0069] The vehicle according to the embodiment of the utility model comprises the sub-frame mounting structure 100 according to the embodiment of the first aspect of the utility model.

[0070] Other structures and operations of the vehicle according to the embodiment of the utility model are known to those skilled in the art and will not be described in detail here.

[0071] For a vehicle according to an embodiment of the present utility model, by providing the subframe mounting structure 100 of the first aspect embodiment described above, the subframe mounting structure 100 is provided with a longitudinal beam 10 and a vertical partition 20. The subframe knuckle 50 is connected to the fixed sleeve 30 through a connecting sleeve 51 and a connecting member 60. The fixed sleeve 30 is fixed to the longitudinal beam 10 through a knuckle mounting plate 40 and the vertical partition 20. The fixed sleeve 30 is arranged on the front side of the vertical partition 20, so that while the subframe mounting structure 100 meets the requirement of the subframe knuckle 50 falling off, a weakening structure can be avoided being provided in the connecting sleeve 51, thereby greatly reducing the probability of abnormal noise occurring in the vehicle and making the use experience of the driver and passengers better.

[0072] Next, reference will be made to Figures 1 - 6 describe the subframe mounting structure 100 according to a specific embodiment of the present utility model.

[0073] As Figures 1 - 6 shown, the subframe mounting structure 100 includes a longitudinal beam 10, a vertical partition 20, a knuckle mounting plate 40, a fixed sleeve 30, a subframe knuckle 50 and a connecting member 60. The subframe is a front subframe and is connected to the subframe knuckle 50. The longitudinal beam 10 includes an outer plate 11 and an inner plate 12. The outer plate 11 and the inner plate 12 cooperate to define an installation cavity 101. The vertical partition 20 is arranged in the installation cavity 101 and is provided with four second flanges 21. Among them, two second flanges 21 in the up-down direction and one second flange 21 in the left-right direction are connected to the inner wall of the inner plate 12 by spot welding, and one second flange 21 is connected to the outer plate 11 by welding. Among them, the outer plate 11 is provided with a second welding hole 111 to facilitate welding operations by welding equipment outside the longitudinal beam 10, so that the outer plate 11 and the second flange 21 can be stably welded and fixed. The bottom of the inner plate 12 is provided with a perforation, and the perforation is located on the front side of the vertical partition 20.

[0074] The knuckle mounting plate 40 is arranged below the longitudinal beam 10 and is connected to the longitudinal beam 10 by spot welding. The knuckle mounting plate 40 has a first flange 42 and is formed with a mounting boss 41. The mounting boss 41 protrudes downward to form a mounting portion. A through hole 401 is formed in the mounting portion. The first flange 42 extends upward to the side wall surface of the longitudinal beam 10 and is spot welded to the outer plate 11 of the longitudinal beam 10.

[0075] The fixed sleeve 30 extends vertically and is located above the installation part. The fixed sleeve 30 has internal threads. The lower end of the fixed sleeve 30 is welded to the installation part and communicates with the through hole 401. The upper end of the fixed sleeve 30 extends into the installation cavity 101 and is located in front of the vertical partition 20. The fixed sleeve 30 is welded to the vertical partition 20. The connecting member 60 is a fastening bolt. The connecting member 60 sequentially passes through the connecting sleeve 51 and the through hole 401 from bottom to top and extends into the fixed sleeve 30 to be threadedly connected with the fixed sleeve 30, thereby fixing the connecting sleeve 51 to the subframe horn mounting plate 40 and the vertical partition 20, and further fixing the subframe horn 50 to the longitudinal beam 10.

[0076] When a collision occurs during the high-speed driving of the vehicle, as shown in Figure 6 shown, under the action of the impact force, the longitudinal beam 10 bends and deforms towards the rear and the side of the vehicle. The subframe horn 50 moves backward under the action of the impact force. The connecting sleeve 51 drives the lower part of the connecting member 60 to move backward, causing the upper part of the connecting member 60 to rotate forward around the fulcrum at the through hole 401, forming a pulling force on the fixed sleeve 30 to move forward. And the vertical partition 20 moves towards the side of the vehicle following the longitudinal beam 10, causing the longitudinal beam 10 to form a pulling force on the vertical partition 20 to move towards the side. Thus, the fixed sleeve 30 and the vertical partition 20 are separated under the action of the pulling force in the front-rear direction and the pulling force in the side direction. The fixed sleeve 30, the connecting member 60 and the subframe horn mounting plate 40 are integrally detached from the longitudinal beam 10 under the action of the gravity of the subframe horn 50 and the impact force, so that the subframe falls off from the subframe mounting structure 100.

[0077] During the daily driving of the vehicle, the connection structure formed by the connecting sleeve 51, the subframe horn mounting plate 40, the fixed sleeve 30 and the vertical partition 20 has good overall structural stability and good connection strength. Thus, the connection position of the subframe horn 50 can maintain good dynamic stiffness performance, thereby well reducing the probability of abnormal noise, enabling the subframe mounting structure 100 to have good NVH performance, and making the ride of the driver and passengers more comfortable.
