[0073] For a thorough understanding of the present disclosure, reference should be made to the following detailed description, in conjunction with the accompanying drawings, in which:

[0074] With the improvement of living standards, cars have become a common means of transportation. Among them, new energy vehicles are widely favored due to their economy and comfort. In the existing new energy vehicles, the arrangement position of the power battery is mostly located in the middle of the chassis or the lower part of the vehicle body. The existing power battery arrangement mode makes the arrangement space of the power battery easily affected by the arrangement of the non-load-bearing body suspension, resulting in that the volume of the power battery is limited, and the endurance mileage is difficult to further improve.

[0075] In view of this, as shown in FIGS. 1-12, the present application provides a body suspension structure 001 for connecting a vehicle frame and a to-be-connected structure 002, the vehicle frame comprising a longitudinal beam 003, wherein the body suspension structure 001 is arranged on the longitudinal beam 003, the body suspension structure 001 comprising an elastic part 100 and a connecting part 3, the connecting part 3 being arranged in the elastic part 100 along the height direction of the vehicle frame, and the connecting part 3 being used for connecting with the longitudinal beam 003 and / or the to-be-connected structure 002. By such arrangement, the body suspension structure 001 is arranged along the height direction of the vehicle frame, avoiding the occupation of the horizontal space of the vehicle frame by the body suspension structure 001, so as to increase the arrangement space of the battery pack (or fuel tank and the like) in the horizontal direction, facilitating the increase of the volume of the battery pack (or fuel tank and the like), and further improving the endurance mileage of the whole vehicle applying the body suspension structure 001.

[0076] The following embodiments 1-4 are some structural form examples of the body suspension structure 001, and the embodiment 5 is a structural form example of the vehicle frame assembly applying the body suspension structure 001 provided by the present application. It can be understood that the following examples are only exemplary descriptions of the technical solutions of the present application for the purpose of understanding, and are not limitations of the present application. The body suspension structure 001 and the vehicle frame assembly provided by the present application include but are not limited to the following examples.

[0077] Embodiment 1

[0078] Referring to FIGS. 1-6, the present application embodiment 1 provides a body suspension structure, which can be used in a vehicle frame assembly for connecting a vehicle frame and a to-be-connected structure 002. The vehicle frame can comprise a longitudinal beam 003, and the to-be-connected structure 002 can comprise a vehicle body cross beam, a vehicle body floor and an engine, etc., that is, the to-be-connected structure 002 can be connected to the longitudinal beam 003 through the body suspension structure.

[0079] As shown in FIGS. 1-4, the body suspension structure 001 is arranged on the longitudinal beam 003, and the body suspension structure 001 comprises an elastic part 100 and a connecting part 3. The elastic part 100 has a first accommodating cavity therein, and the connecting part 3 is arranged in the first accommodating cavity along the height direction of the vehicle frame. One end of the connecting part 3 is used for connecting with the longitudinal beam 003, and the other end of the connecting part 3 is used for connecting with the to-be-connected structure 002.

[0080] As shown in FIG. 1 and FIG. 3, the vehicle body suspension structure 001 of the embodiment is arranged on the longitudinal beam 003, so that the space of the longitudinal beam 003 can be fully utilized. The vehicle body suspension structure 001 of the embodiment is a non-load-bearing vehicle body suspension, which is arranged at the middle part of the longitudinal beam 003. The conventional suspension structure of the frame assembly is usually arranged at the front end and the rear end of the longitudinal beam 003, i.e., the front suspension and the rear suspension, which will not be described herein.

[0081] As shown in FIG. 4 and FIG. 5, the vehicle body suspension structure 001 is arranged along the height direction of the frame, so that the vehicle body suspension structure 001 does not occupy the horizontal space of the frame, thereby increasing the arrangement space of the battery pack 004 (or the fuel tank and the like) in the horizontal direction, facilitating the increase of the volume of the battery pack 004 (or the fuel tank and the like), and further improving the endurance mileage of the whole vehicle using the vehicle body suspension structure 001.

[0082] For example, the elastic part 100 also extends along the height direction of the frame, and a first accommodating cavity is formed in the elastic part 100, which is used for penetrating the connecting part 3. The integrated design of the elastic part 100 facilitates the assembly of the vehicle body suspension structure 001, and can improve the structural strength of the vehicle body suspension structure 001. When actually applied to the frame assembly, the longitudinal beam 003 can be directly connected to the elastic part 100, so that the impact on the longitudinal beam 003 can be buffered by the elastic part 100, thereby improving the connection strength of the vehicle body suspension structure 001. The elastic part 100 can be an elastic material piece, such as rubber, silicone or the like, so that the vehicle body suspension structure 001 has a buffering and damping effect.

[0083] The longitudinal beam 003 can be connected to the middle part of the elastic part 100, so that part of the structure of the elastic part 100 is located in the inner space of the longitudinal beam 003, and the other part of the structure of the elastic part 100 is located in the outer space of the longitudinal beam 003, which can also facilitate the full use of the inner space of the longitudinal beam 003.

[0084] As shown in FIG. 4 and FIG. 5, along the height direction of the frame, the connecting part 3 penetrates into the first accommodating cavity and can extend out from both sides, so as to form a connection with the mounting part 0031 of the longitudinal beam 003 by using the one end extending out. For example, the one end of the connecting part 3 has external threads, and the mounting part 0031 of the longitudinal beam 003 has internal threads, which are threadedly connected, so that the vehicle body suspension structure 001 can be connected to the longitudinal beam 003. This connection method does not need to additionally provide a suspension bracket, simplifies the structure of the frame assembly using the vehicle body suspension structure 001, reduces the processing cost, facilitates the lightweight development, and is also convenient for processing and assembly.

[0085] The other end of the connecting portion 3 can extend to the side of the elastic portion 100 away from the mounting portion 0031 of the longitudinal beam 003, so that a connecting gap is formed between the other end of the connecting portion 3 and the elastic portion 100, which is used to connect the to-be-connected structure 002, so as to realize the connection and fixation of the to-be-connected structure 002. When actually applied to the vehicle frame assembly, the to-be-connected structure 002 can be attached to the top of the elastic portion 100, so that the flexible connection between the to-be-connected structure 002 and the longitudinal beam 003 can be formed by using the vehicle body suspension structure 001, which facilitates the buffering of the vibration between the longitudinal beam 003 and the to-be-connected structure 002, thereby reducing the vibration of the whole vehicle applying the vehicle body suspension structure 001, enhancing the stability of the relative movement of the components of the whole vehicle applying the vehicle body suspension structure 001, and improving the driving comfort and steering stability of the passengers.

[0086] As shown in FIGS. 1 and 3, the vehicle body suspension structure 001 is directly arranged on the longitudinal beam 003, and the flexible connection between the to-be-connected structure 002 and the longitudinal beam 003 is realized by using the vehicle body suspension structure 001, which can simplify the vehicle frame structure and facilitate the lightweight of the vehicle frame assembly applying the vehicle body suspension structure 001.

[0087] In some embodiments, the to-be-connected structure 002 is connected between the other end of the connecting portion 3 and the elastic portion 100.

[0088] Exemplarily, when actually applied to the vehicle frame assembly, the to-be-connected structure 002 can be attached to the top of the elastic portion 100, so that the flexible connection between the to-be-connected structure 002 and the longitudinal beam 003 can be formed by using the vehicle body suspension structure 001, which facilitates the buffering of the vibration between the longitudinal beam 003 and the to-be-connected structure 002, thereby reducing the vibration of the whole vehicle applying the vehicle body suspension structure 001, enhancing the stability of the relative movement of the components of the whole vehicle applying the vehicle body suspension structure 001, and improving the driving comfort and steering stability of the passengers.

[0089] In some embodiments, the connecting portion 3 has opposite first and second ends, the first end is used to connect with the mounting portion 0031 of the longitudinal beam 003, and the second end extends to the outside of the elastic portion 100.

[0090] Exemplarily, the connecting portion 3 can be a connecting bolt, which is arranged in the first accommodating cavity and can extend out of the first accommodating cavity. The mounting portion 0031 of the longitudinal beam 003 can be a connecting nut, the first end of the connecting bolt has external threads, and the connecting nut has internal threads, which are threadedly connected, so as to connect the vehicle body suspension structure 001 to the longitudinal beam 003.

[0091] The mounting portion 0031 of the longitudinal beam 003 can be welded to the longitudinal beam 003, which can improve the strength of the frame assembly to which the body suspension structure 001 is applied and reduce the assembly difficulty of the frame assembly to which the body suspension structure 001 is applied.

[0092] As shown in FIGS. 4 and 5, the second end of the connecting portion 3 can extend to a side of the elastic portion 100 away from the mounting portion 0031 of the longitudinal beam 003, so that a connecting gap is formed between the second end of the connecting portion 3 and the elastic portion 100, and the connecting gap can be used to connect the to-be-connected structure 002.

[0093] In some embodiments, the body suspension structure 001 further comprises a fixing portion 300, the fixing portion 300 is arranged on the outer periphery of the elastic portion 100, and two ends of the fixing portion 300 are connected with the elastic portion 100 and the longitudinal beam 003 respectively.

[0094] As shown in FIGS. 4 and 5, the fixing portion 300 is a connecting structure, which is used to connect the elastic portion 100 and the longitudinal beam 003. For example, the elastic portion 100 can have a ring structure, the fixing portion 300 can be arranged around the outer periphery of the elastic portion 100, or the fixing portion 300 can be arranged on a part of the outer periphery of the elastic portion 100, one end of the fixing portion 300 is connected with the elastic portion 100 by welding, screwing or the like, and the other end of the fixing portion 300 is connected with the upper surface of the longitudinal beam 003 by welding, screwing or the like.

[0095] On the other hand, the fixing portion 300 can also be used to limit the elastic portion 100, which is convenient for the assembly of the body suspension structure 001 and can improve the stability of the frame assembly to which the body suspension structure 001 is applied.

[0096] In the height direction of the frame, the fixing portion 300 is usually located in the middle of the elastic portion 100, which can improve the connection strength between the body suspension structure 001 and the longitudinal beam 003. In addition, part of the structure of the elastic portion 100 is located in the inner space of the longitudinal beam 003, and the other part of the structure of the elastic portion 100 is located in the outer space of the longitudinal beam 003, which can also facilitate the full use of the inner space of the longitudinal beam 003.

[0097] In some embodiments, the fixing portion 300 surrounds the outer periphery of the elastic portion 100 and extends in the radial direction of the body suspension structure 001, the fixing portion 300 has a third end and a fourth end, the third end is connected with the elastic portion 100, and the fourth end is connected with the upper surface of the longitudinal beam 003.

[0098] As shown in FIG. 4 and FIG. 5, the fixing portion 300 is arranged around the outer periphery of the elastic portion 100, that is, the fixing portion 300 is attached to the outer periphery of the elastic portion 100, which can improve the connection reliability of the fixing portion 300 and the elastic portion 100, and further improve the connection reliability between the vehicle body suspension structure 001 and the longitudinal beam 003. Moreover, the fixing portion 300 is arranged around the outer periphery of the elastic portion 100, which enables the fixing portion 300 to limit and fix the elastic portion 100 from the outer periphery of the elastic portion 100, so that the stress on the outer periphery of the elastic portion 100 is uniform, and the stability of the vehicle frame assembly using the vehicle body suspension structure 001 can be improved.

[0099] In addition, the fixing portion 300 extends along the radial direction of the vehicle body suspension structure 001, so that the fixing portion 300 can be connected to the elastic portion 100 and the longitudinal beam 003 along the radial direction of the vehicle body suspension structure 001, which facilitates to increase the connection area and further improve the connection reliability.

[0100] For example, along the radial direction of the vehicle body suspension structure 001, the fixing portion 300 has a third end and a fourth end, the third end is connected to the elastic portion 100 by welding, screwing or the like, and the fourth end is connected to the upper surface of the longitudinal beam 003 by welding, screwing or the like, so that the connection between the vehicle body suspension structure 001 and the longitudinal beam 003 can be realized by the fixing portion 300.

[0101] In some embodiments, the elastic portion 100 has a limiting flange 11, and the limiting flange 11 abuts against the fourth end.

The limiting flange 11 is used to abut against the fourth end of the fixing portion 300, so that the limiting flange 11 can guide and position the connection position between the vehicle body suspension structure 001 and the longitudinal beam 003, which facilitates the assembly of the vehicle frame assembly using the vehicle body suspension structure 001, and reduces the assembly difficulty.

[0103] In some embodiments, along the height direction of the vehicle body suspension structure 001, the cross section of the fixing portion 300 is Z-shaped.

[0104] For example, the fixing portion 300 can be a Z-shaped annular structure, one end of which is connected to the elastic portion 100, and the other end of which is connected to the upper surface of the longitudinal beam 003, so that the connection between the vehicle body suspension structure 001 and the longitudinal beam 003 can be realized by the fixing portion 300.

[0106] As shown in FIGS. 4 and 5, the gasket 4 is arranged on one side of the elastic part 100 close to the longitudinal beam 003, so that the gasket 4 is clamped between the elastic part 100 and the mounting part 0031 of the longitudinal beam 003 during assembly. On the one hand, this can facilitate the assembly of the elastic part 100 and also protect the longitudinal beam 003. On the other hand, the gasket 4 also has a certain buffering and damping capacity, thereby enhancing the buffering and damping effect of the vehicle body suspension structure 001.

[0107] In some embodiments, the vehicle body suspension structure 001 further comprises a sleeve 5, which is sleeved on the outer side of the connecting part 3. The outer wall of the sleeve 5 is in abutment with the inner wall of the elastic part 100, and the end of the sleeve 5 is in abutment with the gasket 4.

[0108] As shown in FIGS. 4 and 5, the sleeve 5 is sleeved on the outer side of the connecting part 3, and the outer wall of the sleeve 5 is in abutment with the elastic part 100. In the actual assembly process of the vehicle body suspension structure 001, the gasket 4 is first assembled so that the gasket 4 is in abutment with the mounting part 0031 of the longitudinal beam 003. Then, the sleeve 5, the elastic part 100, and the to-be-connected structure 002 are sequentially assembled. Finally, the connecting part 3 is assembled, and the connecting part 3 is connected with the mounting part 0031 of the longitudinal beam 003.

This can facilitate assembly, reduce the assembly difficulty of the vehicle body suspension structure 001, and thus improve the assembly efficiency of the vehicle body suspension structure 001.

[0117] As shown in FIG. 1 and FIG. 2, the body suspension structure 001 is arranged on the longitudinal beam 003, so that the space of the longitudinal beam 003 can be fully utilized. The body suspension structure 001 of the embodiments of the present application is a non-load-bearing body suspension structure and is located in the middle of the longitudinal beam 003. The conventional suspension structure included in the frame assembly is usually located at the front end and the rear end of the longitudinal beam 003, that is, forms a front suspension and a rear suspension, which will not be described herein.

[0118] The to-be-connected structure 002 is connected between the first elastic portion 1 and the second elastic portion 2, so that the to-be-connected structure 002 can be attached to the first elastic portion 1 and the second elastic portion 2, thereby forming a flexible connection between the to-be-connected structure 002 and the longitudinal beam 003 through the body suspension structure 001, facilitating the buffering of the vibration between the longitudinal beam 003 and the to-be-connected structure 002, thereby reducing the vibration of the whole vehicle using the body suspension structure 001, enhancing the stability of the relative movement of the components of the whole vehicle using the body suspension structure 001, and improving the driving comfort and the steering stability of the occupants.

[0119] As shown in FIG. 2, the body suspension structure 001 is directly arranged on the longitudinal beam 003 through the connecting portion 3, and the to-be-connected structure 002 and the longitudinal beam 003 are flexibly connected through the body suspension structure 001, which can simplify the frame structure and facilitate the lightweight of the frame assembly using the body suspension structure 001. The body suspension structure 001 is arranged in the height direction of the frame, avoiding the occupation of the horizontal space of the frame by the body suspension structure 001, thereby increasing the arrangement space of the battery pack 004 (or the fuel tank, etc.) in the horizontal direction, facilitating the increase of the volume of the battery pack 004 (or the fuel tank, etc.), and further improving the endurance mileage of the whole vehicle using the body suspension structure 001.

[0121] As shown in FIGS. 7 and 8, the first elastic part 1 and the second elastic part 2 are stacked along the height direction of the frame, i.e., the height direction of the body suspension structure 001, and form a first accommodating cavity for arranging the connecting part 3. The first elastic part 1 is away from the longitudinal beam 003, and the second elastic part 2 is close to the longitudinal beam 003, i.e., the second elastic part 2 is located on the side of the first elastic part 1 close to the longitudinal beam 003. In actual application to the frame assembly, the second elastic part 2 is located between the first elastic part 1 and the longitudinal beam 003, so that most of the structure of the body suspension structure 001 is located outside the longitudinal beam 003, avoiding the occupation of the internal space of the longitudinal beam 003 and facilitating the optimized use of the internal space of the longitudinal beam 003. The first elastic part 1 and the second elastic part 2 can be elastic material parts, such as rubber, silicone, etc., so that the body suspension structure 001 has a buffering and damping effect.

[0122] For example, the partial connecting part 3 is arranged in the first accommodating cavity and can extend from the side of the second elastic part 2 close to the longitudinal beam 003, i.e., the side away from the first elastic part 1, so as to facilitate the connection between the extended connecting part 3 and the mounting part 0031 of the longitudinal beam 003. For example, the extended connecting part 3 has external threads, and the mounting part 0031 of the longitudinal beam 003 has internal threads, and the two are threadedly connected, so that the body suspension structure 001 can be connected to the longitudinal beam 003. This connection method does not require additional suspension brackets, simplifies the structure of the frame assembly using the body suspension structure 001, reduces the processing cost, facilitates lightweight development, and facilitates processing and assembly.

[0123] In some embodiments, the first elastic part 1 has a first through hole, and the second elastic part 2 has a second through hole, and the first through hole and the second through hole are communicated to form the first accommodating cavity.

[0124] For example, the first through hole and the second through hole can be circular through holes, and the first through hole and the second through hole are communicated to form the first accommodating cavity for arranging the connecting part 3 and the to-be-connected structure 002. The first through hole and the second through hole are circular through holes, which is convenient for matching the arc-shaped outer periphery of the connecting part 3 and facilitating the assembly of the body suspension structure 001.

[0125] In other embodiments, according to the specific shape of the connecting part 3, the shape of the first through hole and the second through hole can also be adjusted, such as rectangular holes, elliptical holes, or other shaped through holes.

[0129] As shown in FIG. 8, the first end 31 of the connecting part 3 abuts against or is connected to the side of the first elastic part 1 away from the second elastic part 2, so as to limit the first elastic part 1 by the first end 31 (e.g., a connecting flange) of the connecting part 3, thereby ensuring the connection reliability of the vehicle body suspension structure 001.

[0130] In some embodiments, the vehicle body suspension structure 001 further comprises a gasket 4, which is arranged on the side of the second elastic part 2 away from the first elastic part 1.

[0131] As shown in FIG. 8, the gasket 4 is arranged on the side of the second elastic part 2 away from the first elastic part 1, i.e., the gasket 4 is arranged on the side of the second elastic part 2 close to the longitudinal beam 003. In actual application to the vehicle frame assembly, the gasket 4 is arranged between the second elastic part 2 and the longitudinal beam 003, which can facilitate the assembly of the second elastic part 2 and protect the longitudinal beam 003, and the gasket 4 also has a certain buffering and damping capacity, thereby enhancing the buffering and damping effect of the vehicle body suspension structure 001.

[0132] In some embodiments, the vehicle body suspension structure 001 further comprises a sleeve 5, which is arranged on the outer side of the connecting part 3, the outer wall of the sleeve 5 abuts against the first elastic part 1 and the second elastic part 2, and the two ends of the sleeve 5 abut against the first elastic part 1 and the gasket 4, respectively.

[0133] As shown in FIG. 8, the sleeve 5 is sleeved on the outside of the connecting part 3, and the outer wall of the sleeve 5 abuts against the first elastic part 1 and the second elastic part 2. In the actual assembly process of the vehicle body suspension structure 001, first, the gasket 4 is assembled to make the gasket 4 adhere to the longitudinal beam 003; then, the second elastic part 2, the to-be-connected structure 002, the first elastic part 1 and the sleeve 5 are sequentially assembled; finally, the connecting part 3 is assembled to make the connecting part 3 connected with the mounting part 0031 of the longitudinal beam 003.

[0136] For example, an included angle is formed between the first segment and the second segment of the sleeve 5, and the included angle is matched with the shape of the first elastic part 1 and the shape of the connecting part 3. As shown in FIG. 8, the first segment of the sleeve 5 is a horizontal segment, which is used to abut against the side of the first elastic part 1 away from the second elastic part 2 to limit and protect the first elastic part 1; and the second segment of the sleeve 5 is a vertical segment, which has a supporting effect and abuts against the gasket 4.

[0138] For example, the first elastic part 1 and the second elastic part 2 are both annular structures in the embodiments of the present application, that is, the outer periphery of the first elastic part 1 and the outer periphery of the second elastic part 2 are both smooth, so that damage to the to-be-connected structure 002 in the assembly process can be avoided, and the reliability of the vehicle body suspension structure 001 is improved. The inner wall of the first elastic part 1 and the inner wall of the second elastic part 2 circumferentially adhere to the outer wall of the second segment of the sleeve 5, respectively, so that the fixation of the first elastic part 1 and the second elastic part 2 can be facilitated.

[0139] In some embodiments, the sleeve 5 is integrally connected to the first elastic part 1.

[0140] For example, the sleeve 5 can be welded to the first elastic part 1 to form an integrated structure, which can facilitate assembly, reduce the assembly difficulty of the vehicle body suspension structure 001 and improve the assembly efficiency of the vehicle body suspension structure 001.
