Description

Technical Field

[0001] This utility model relates to the field of automotive suspension system technology, and in particular to an automobile and its suspension subframe. Background Technology

[0002] The battery pack of a new energy vehicle is installed on the chassis of the vehicle. During the driving process, the vehicle will inevitably encounter uneven road surfaces. Therefore, the battery pack of a new energy vehicle is at risk of being impacted.

[0003] To protect the battery pack from impacts, a protective beam is installed on the crossbeam of the vehicle floor in front of the battery pack. However, the installation requires lifting the entire vehicle floor and then installing it from below, making the installation quite difficult.

[0004] Therefore, how to improve the ease of installation of the protective beam of the battery pack has become a technical problem that needs to be solved by those skilled in the art. Utility Model Content

[0005] This utility model provides an automobile and its suspension subframe to solve the problem of difficult installation of protective beams in the prior art.

[0006] To solve the aforementioned problems, this utility model provides a suspension subframe, comprising:

[0007] The suspension subframe body includes a first contact surface facing the ground;

[0008] The anti-collision beam is fixedly connected to the suspension subframe body, and includes a second abutment surface that abuts against the first abutment surface.

[0009] According to one embodiment of the present invention, the anti-collision beam includes:

[0010] A connecting plate, fixedly connected to the suspension subframe body, includes the second contact surface;

[0011] A crash plate is fixed to the side of the connecting plate away from the suspension subframe body.

[0012] According to one embodiment of the present invention, the extension surface of the anti-collision plate is perpendicular to the extension surface of the connecting plate.

[0013] According to one embodiment of the present invention, the size range of the anti-collision plate in the direction perpendicular to the extension surface of the connecting plate is 30mm-50mm.

[0014] According to one embodiment of the present invention, the anti-collision plate is fixedly connected to the length side of the connecting plate.

[0015] According to one embodiment of the present invention, the connecting plate includes:

[0016] The plate body is fixedly connected to the anti-collision plate;

[0017] An abutment is fixed to the plate and protrudes from the plane of the plate away from the anti-collision plate, and a second abutment surface is located on the abutment.

[0018] According to one embodiment of the present invention, the plate body has a first connecting hole, and the abutting member passes through the first connecting hole and is fixed to the plate body.

[0019] According to one embodiment of the present invention, the abutment member has a second connecting hole, the suspension subframe body has a third connecting hole, the third connecting hole corresponds to the second connecting hole, and the suspension subframe further includes:

[0020] A connecting bolt, which connects the suspension subframe body and the anti-collision beam through the second connecting hole and the third connecting hole.

[0021] According to one embodiment of the present invention, the material of the anti-collision beam includes steel.

[0022] To address the aforementioned problems, this utility model also provides an automobile, including the suspension subframe as described above.

[0023] This utility model provides an automobile and its suspension subframe, wherein the suspension subframe includes a suspension subframe body and a crash beam, which are fixedly connected. The suspension subframe body includes a first abutment surface facing the ground, and the crash beam includes a second abutment surface, which abuts against the first abutment surface. The suspension subframe provided by this utility model, including the crash beam, allows for installation in two ways: either the crash beam can be fixedly connected to the suspension subframe body first, followed by the installation of the suspension subframe; or the suspension subframe body can be installed first, followed by the installation of the crash beam. As can be seen, the suspension subframe and anti-collision beam provided by this utility model are easy to install, without having to lift the entire vehicle body, which reduces the complexity of anti-collision beam installation and improves the ease of installing the battery pack protective beam. Furthermore, since the anti-collision beam is fixed to the suspension subframe body, when it is hit by a road surface, the force transmission path is: anti-collision beam, suspension subframe body, and vehicle floor. During the transmission process, the force is gradually offset, thereby reducing the risk of deformation to the vehicle body and thus reducing vehicle operating costs.

[0024] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples. Moreover, without contradiction, those skilled in the art can combine and integrate the different embodiments or examples described in this specification, as well as the features of different embodiments or examples.

[0036] The following is combined Figures 1-3 The present invention describes the automobile and its suspension subframe provided in the embodiments of the present invention.

[0037] Please refer to Figure 1 and Figure 2 , Figure 1 This is a front view of the suspension subframe provided by this utility model; Figure 2 This is a bottom view of the suspension subframe provided by this utility model.

[0038] For ease of description, this application first introduces the suspension subframe provided in the embodiments of this application, such as... Figure 1 and Figure 2 As shown, the suspension subframe provided in this embodiment includes a suspension subframe body 1 and a crash beam 2, wherein:

[0039] The suspension subframe body 1 includes a first contact surface facing the ground;

[0040] The anti-collision beam 2 is fixedly connected to the suspension subframe body 1, and includes a second abutting surface, which abuts against the first abutting surface.

[0041] It is easy to understand that "facing the ground" as used in this article refers to the side of the suspension subframe body 1 facing the ground when the vehicle is in a normal parking or driving state after being mounted on the car.

[0042] To ensure the anti-collision effect at a lower cost, the material of the anti-collision beam can include steel, specifically Q345.

[0043] Therefore, when installing the suspension subframe provided by this utility model, one can either first abut the second contact surface of the anti-collision beam 2 with the first contact surface of the suspension subframe body 1, then fix the anti-collision beam 2 to the suspension subframe body 1, and then install the suspension subframe, thereby realizing the installation of the anti-collision beam; or one can first install the suspension subframe body 1 on the vehicle body, and then install the anti-collision beam 2 on the suspension subframe body 1 with the second contact surface abutting the first contact surface.

[0044] Of course, in a car, the suspension subframe includes two parts. The anti-collision beam 2 is installed at the rear of the vehicle body. Compared with the front and rear positions of the battery pack on the vehicle body, the anti-collision beam 2 of the suspension subframe installed at the front is located in front of the battery pack, and the anti-collision beam 2 of the suspension subframe installed at the rear is located behind the battery pack.

[0045] Thus, when a vehicle equipped with the suspension subframe provided by this utility model is in motion, and encounters uneven road surfaces, the anti-collision beam 2, located below the battery pack, in front of the battery pack (when driving in forward gear), or behind the battery pack (when driving in reverse gear), will be the first to be impacted, thereby protecting the battery pack.

[0046] As can be seen, the suspension subframe and anti-collision beam provided by this utility model are easy to install, without having to lift the entire vehicle body, which reduces the complexity of anti-collision beam installation and improves the ease of installing the battery pack protective beam. Furthermore, since the anti-collision beam is fixed to the suspension subframe body, when it is hit by a road surface, the force transmission path is: anti-collision beam, suspension subframe body, and vehicle floor. During the transmission process, the force is gradually offset, thereby reducing the risk of deformation to the vehicle body, which can reduce vehicle operating costs. Moreover, the replacement cost when the suspension subframe body is damaged is also lower than the replacement cost of the vehicle floor.

[0047] In one specific implementation, please refer to Figure 3 , Figure 3 This is a schematic diagram of the anti-collision beam of the suspension subframe provided by this utility model.

[0048] As shown in the figure, the anti-collision beam 2 of the suspension subframe provided in this embodiment of the application may include:

[0049] The connecting plate 21 is fixedly connected to the suspension subframe body 1 and includes a second contact surface;

[0050] The anti-collision plate 22 is fixed to the side of the connecting plate 21 away from the suspension subframe body 1.

[0051] The connecting plate 21 allows the anti-collision beam 2 to be easily connected to the suspension subframe body 1. The anti-collision plate 22 ensures the anti-collision effect. Furthermore, the connecting plate 21 and the anti-collision plate 22 can achieve the functional requirements with a very simple structure, reducing the complexity of the anti-collision beam 2, reducing the processing difficulty, and reducing the cost of use.

[0052] Of course, in other embodiments, the anti-collision beam 2 may also have other structures, such as using angle steel to fix it to the suspension subframe body 1, and connecting it to the angle steel with some profiles to achieve the anti-collision function.

[0053] Specifically, in order to ensure the anti-collision effect without wasting anti-collision materials, in one specific embodiment, the extension surface of the anti-collision plate 22 is perpendicular to the extension surface of the connecting plate 21.

[0054] In other embodiments, the angle between the extended surface of the anti-collision plate 22 and the extended surface of the connecting plate 21 can be an acute angle or an obtuse angle.

[0055] In some embodiments, to ensure the anti-collision effect, the size range of the anti-collision plate 22 in the direction perpendicular to the extension surface of the connecting plate 21 can be 30mm-50mm. Specifically, for example: 35mm, 38mm, 40mm, 42mm, 45mm, etc.

[0056] In order to detect collision risks as early as possible during vehicle operation, in some specific embodiments, the anti-collision plate 22 is fixedly connected to the length side of the connecting plate 21.

[0057] It is easy to understand that when the suspension subframe provided in this application embodiment is installed at the front end of the vehicle, the anti-collision plate 22 is fixedly connected to the long side of the connecting plate 21 near the front end of the vehicle. When the suspension subframe provided in this application embodiment is installed at the rear end of the vehicle, the anti-collision plate 22 is fixedly connected to the long side of the connecting plate 21 near the rear end of the vehicle.

[0058] To facilitate the connection between the connecting plate 21 and the suspension subframe body 1, in one specific embodiment, the connecting plate 21 includes:

[0059] Plate 211 is fixedly connected to anti-collision plate 22;

[0060] The abutment 212 is fixed to the plate 211 and protrudes from the plane of the plate 211 away from the anti-collision plate 22. The second abutment surface is located on the abutment 212.

[0061] The plate 211 improves the strength of the connecting plate 21 and ensures the strong connection with the anti-collision plate 22. The abutment 212 reduces the size of the second abutment surface and reduces the processing difficulty of the first and second abutment surfaces. On the other hand, since the abutment 212 protrudes from the side of the plate 211 away from the anti-collision plate 22, it can ensure the abutment requirements while allowing a certain gap between the plate 211 and the suspension subframe body 1 to accommodate some structures of the suspension subframe body 1.

[0062] To facilitate the connection between the abutment 212 and the plate 211, in some specific embodiments, the plate 211 may have a first connection hole, through which the abutment 212 passes and is fixed to the plate 211.

[0063] Specifically, when fixing the abutment 212 to the plate 211, the abutment 212 can protrude from the plane of the plate 211 away from the anti-collision plate 22 while protruding from the side of the plate 211 close to the anti-collision plate 22, or the abutment 212 can not protrude from the side of the plate 211 close to the anti-collision plate 22.

[0064] When both ends of the abutment 212 protrude from the plate 211, it not only facilitates the processing of the second abutment surface and the connection with the suspension subframe body 1, but also reduces the size requirements of the abutment 212 and the connection requirements with the plate 211.

[0065] To facilitate the connection between the anti-collision beam 2 and the suspension subframe body 1, in one specific embodiment, the abutment member 212 of the suspension subframe provided in this application may also have a second connecting hole, and the suspension subframe body may have a third connecting hole corresponding to the second connecting hole. The suspension subframe further includes:

[0066] Connecting bolt 3 connects the suspension subframe body 1 and the anti-collision beam 2 through the second connecting hole and the third connecting hole.

[0067] In this way, when it is necessary to connect the suspension subframe body 1 and the anti-collision beam 2, it is only necessary to pass the connecting bolt 3 through the second connecting hole and the third connecting hole, and then tighten it with the nut of the connecting bolt 3, which is convenient and simple.

[0068] To address the aforementioned issues, this application also provides an automobile, including the suspension subframe provided in any of the foregoing embodiments.

[0069] The automobile provided in this application embodiment has a convenient anti-collision beam for its suspension subframe, which does not require lifting the entire vehicle body, thus reducing the complexity of anti-collision beam installation and improving the ease of installing the battery pack protective beam. Furthermore, since the anti-collision beam is fixed to the suspension subframe body, when it is hit by a road surface, the force transmission path is: anti-collision beam, suspension subframe body, and vehicle floor. During the transmission process, the force is gradually offset, thereby reducing the risk of deformation to the vehicle body, which can reduce vehicle operating costs. Moreover, the replacement cost when the suspension subframe body is damaged is lower than the replacement cost of the vehicle floor.

[0070] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
