However, this method often fails to play a good role in force transmission and also fails to ensure the connection strength between the longitudinal beam and the shotgun beam and other parts of the vehicle body. Summary of the Invention

Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0034] In the embodiments of this application, directional terms such as "upper," "lower," and "side" are generally used in the following ways: Figure 1 The relative positions shown are based on the given information, and these directional terms are used only to more clearly describe the relationships between structures, not to describe absolute positions. Positions may change when the product is placed in different orientations; for example, "up" and "down" may be interchanged.

[0035] Unless otherwise defined, all technical terms used in the embodiments of this application have the same meaning as commonly understood by those skilled in the art. Some technical terms appearing in the embodiments of this application are described below.

[0036] To make the technical solutions and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0037] like Figures 1 to 10 As shown in the figure, this application provides a connection structure 1, which is applied to a vehicle. The vehicle can be a gasoline-powered vehicle, a hybrid vehicle, a pure electric vehicle, etc., and this application does not make any specific limitation.

[0038] like Figure 3 As shown, the connecting structure 1 includes a connecting part 11, which includes a main body plate 111 connected to the main body plate 111 and a side plate 112 connected to the edge of the main body plate 111. The main body plate 111 extends along a first direction Y, and the side plate 112 protrudes relative to the main body plate 111 along a second direction X. The first direction Y is perpendicular to the second direction X. The side plate 112 is adapted to be connected to the longitudinal beam 100 and the shotgun beam 200 of the vehicle. A flange 113 is provided at one end of the side plate 112 away from the main body plate 111. The flange 113 is adapted to be connected to the mounting vertical plate 300 of the vehicle.

[0039] The longitudinal beam 100 and the shotgun beam 200 are located on the front side of the vehicle. The longitudinal beam 100 and the shotgun beam 200 extend along the direction of travel of the vehicle (i.e., the longitudinal direction of the vehicle) and are distributed at intervals along the lateral direction of the vehicle. The mounting plate 300 is located on the front side of the vehicle.

[0040] like Figure 3 As shown, the main body plate 111 is roughly rectangular in shape. The length direction of the main body plate 111 is parallel to the first direction Y, the thickness direction of the main body plate 111 is parallel to the second direction X, and the width direction of the main body plate 111 is parallel to the third direction Z. The first direction Y, the second direction X, and the third direction Z are perpendicular to each other.

[0041] The connecting part 11 is shell-shaped or block-shaped, and the side plate 112 is set at an angle to the main plate 111, for example, the angle between the side plate 112 and the main plate 111 is 90°.

[0042] For example, the connecting part 11 is a stamped part or a rolled part.

[0043] There are at least two side plates 112, which are arranged opposite each other along the third direction Z or along the first direction Y to ensure the connection strength between the connecting part 11 and the mounting vertical plate 300.

[0044] like Figure 3 As shown, the flange 113 of the side panel 112 is folded outward relative to the side panel 112. For example, the included angle between the side panel 112 and the flange 113 is 90°.

[0045] The flange 113 and the main body plate 111 are positioned opposite each other along the second direction X, such as Figure 4 As shown, the flange 113 is installed on the mounting plate 300 by welding, fastener connection, or other means to fix the connecting structure 1. When the connecting structure 1 is installed on the mounting plate 300, the connecting part 11 protrudes relative to the mounting plate 300 along the second direction X.

[0046] like Figure 9 and Figure 10 As shown, the vehicle's longitudinal beam 100 and shotgun beam 200 extend along the second direction X and are spaced apart along the first direction Y. The front ends of the longitudinal beam 100 and the shotgun beam 200 are respectively connected to the connecting structure 1, realizing the overlap of the shotgun beam 200, the mounting vertical plate 300, and the longitudinal beam 100. This helps to disperse and transmit the collision force, improve the force transmission effect of the shotgun beam 200, and improve the structural evaluation under small offset conditions.

[0047] For example, the cross-section of the front end of the longitudinal beam 100 is approximately "U"-shaped. The front end of the longitudinal beam 100 has an opening on one side in its width direction (i.e., the first direction Y). The connecting part 11 can extend into the space enclosed by the longitudinal beam 100 along the second direction X, and the flange 113 can abut against the end of the longitudinal beam 100, thus limiting the longitudinal beam 100. Optionally, the three inner sidewalls of the longitudinal beam 100 abut against the side plate 112 on the same side, and the side plate 112 provides sufficient support for the longitudinal beam 100. Optionally, the inner sidewalls of the longitudinal beam 100 and the side plate 112 are connected by welding.

[0048] This configuration allows the connecting part 11 to support and reinforce the front end of the longitudinal beam 100, thereby increasing the connection strength between the longitudinal beam 100 and the connecting structure 1 in the first direction Y and / or the second direction X, and improving the connection stability and reliability of the longitudinal beam 100.

[0049] For example, such as Figure 6 As shown, the front end of the shotgun beam 200 is provided with multiple folded welding edges 201. The welding edges 201 are attached to the side plate 112 or the main plate 111 so as to weld the front end of the shotgun beam 200 to the connecting part 11, ensuring that the shotgun beam 200 and the connecting part 11 have sufficient connection strength.

[0050] In the automotive technology field, to improve a vehicle's MPDB compatibility rating and reduce penalty points, it is necessary to: 1. Ensure the integrity of the overall vehicle body structure path, including both the upper shotgun beam 200 and the longitudinal beam 100 as force transmission paths, as well as the lower force transmission path of the energy-absorbing box and subframe beam; 2. Ensure that the lateral structure of the upper and lower paths at the front of the vehicle has sufficient coverage and support strength. For small offset collisions (25% collision contact), the obstacle avoidance overlap is small, the energy transmission paths are few, and the front longitudinal beam 100 basically does not participate in deformation and energy absorption. This necessitates adding an additional energy transmission path, i.e., setting up the shotgun beam 200. Considering the requirements of these two scenarios, to reduce MPDB penalties and improve the structural evaluation for small offset collisions, it is necessary to add the upper shotgun beam 200 transmission path, extending it to the very front of the longitudinal beam 100. However, simply extending the shotgun without connecting it to other structural components will not provide effective force transmission.

[0051] To address the aforementioned technical problems, the connection structure 1 provided in this application embodiment, by setting a connection part 11 and having a side plate 112 protruding relative to the main plate 111 along the second direction X, allows the side plate 112 and the main plate 111 to be inserted into the inner cavity of the longitudinal beam 100, thereby connecting the longitudinal beam 100 and the connection structure 1. Simultaneously, the side plate 112 connects the shotgun beam 200 to the connection structure 1, and the flange 113 connects the mounting vertical plate 300 to the connection structure 1. This connects the mounting vertical plate 300, the longitudinal beam 100, and the shotgun beam 200 together, ensuring the connection strength between the front end of the longitudinal beam 100 and the shotgun beam 200 and other components of the vehicle body. It also ensures that the vehicle's force transmission path has sufficient coverage and support strength in the Y direction, improving the energy transmission effect of the shotgun beam 200, fully utilizing the role of the shotgun beam 200 in MPDB and small offset conditions, reducing MPDB penalties, and improving the structural evaluation in small offset conditions.

[0052] In a further embodiment, there are multiple side plates 112, which are sequentially connected and surround the main body plate 111 to form a first cavity, so that the connecting part 11 has a box-shaped structure with one end open.

[0053] For example, such as Figure 3 As shown, there are four side plates 112, which are distributed along the four edges of the main body plate 111. The four side plates 112 are connected in sequence to form a ring, so that the connecting part 11 presents a shell-like structure. The opening of the first cavity formed by the side plates 112 and the main body plate 111 faces the side where the vertical plate 300 is installed.

[0054] In this embodiment, the side plate 112 is in the form of a sheet or plate, and the connecting part 11 is in the form of a semi-closed box structure. While reducing the weight of the connecting part 11, the side plate 112 is used to support and strengthen the longitudinal beam 100, ensuring the connection strength between the front end of the longitudinal beam 100 and the connecting structure 1.

[0055] In another alternative embodiment, the connecting portion 11 is a solid block and does not have a first cavity. The connecting portion 11 has a certain thickness. The outer peripheral wall of the connecting portion 11 forms a side plate 112. The flange 113 is located at one end of the connecting portion 11 in the second direction X and extends outward from the connecting portion 11.

[0056] In one embodiment, the shape of a portion of the connecting portion 11 is adapted to the shape of the end of the longitudinal beam 100, so that a portion of the connecting portion 11 extends into the inner cavity of the longitudinal beam 100, and the plurality of side plates 112 abut against the inner wall of the longitudinal beam 100.

[0057] like Figure 5As shown, the longitudinal beam 100 is arranged around the left side of the connecting structure 1. The shape of the left side region of the connecting structure 1 is adapted to the shape of the front end of the longitudinal beam 100. The three inner walls of the longitudinal beam 100 are respectively connected to the three side plates 112 of the connecting part 11. Each inner wall is in close contact with one side plate 112 to increase the contact area between the connecting part 11 and the longitudinal beam 100 and improve the connection strength between the front end of the longitudinal beam 100 and the connecting structure 1.

[0058] In this embodiment, by setting the shape of a portion of the connecting part 11 to match the shape of the end of the longitudinal beam 100, it is convenient for a portion of the connecting part 11 to be inserted into the longitudinal beam 100. The side plate 112 is used to support and strengthen the longitudinal beam 100, while increasing the contact area between the connecting part 11 and the longitudinal beam 100, thereby improving the connection strength between the front end of the longitudinal beam 100 and the connecting structure 1.

[0059] In one specific embodiment, the connecting structure 1 further includes a support portion 12, which is installed on the side of the main body plate 111 away from the flange 113. The support portion 12 includes a connecting plate 121, one end of which is connected to the main body plate 111, and the other end of which is adapted to be connected to the longitudinal beam 100. The connecting plate 121 is inclined to the main body plate 111.

[0060] like Figure 1 and Figure 2 As shown, the support part 12 is located on one side of the main body plate 111 in the second direction X, and the support part 12 and the flange 113 are located on both sides of the main body plate 111 in the second direction X.

[0061] The connecting plate 121 is in the form of a sheet or plate. The connecting plate 121 is used to connect the main plate 111 and the longitudinal beam 100. One end of the connecting plate 121 is connected to the main plate 111 by welding, fasteners or other means, and the other end is inclined towards the longitudinal beam 100 and connected to the longitudinal beam 100 by welding, fasteners or other means.

[0062] In this embodiment, by setting the connecting plate 121 and the main plate 111 to be inclined, it is beneficial to improve the connection strength between the longitudinal beam 100 and the connecting structure 1, prevent the longitudinal beam 100 from shaking in the first direction Y, and improve the structural strength of the longitudinal beam 100 and its ability to withstand side collisions.

[0063] In an optional embodiment, there are two support parts 12, which are symmetrically arranged along the first direction Y. The two support parts 12 are located on both sides of the longitudinal beam 100 in the first direction Y, which further restricts the swaying and deformation of the longitudinal beam 100 in the first direction Y and improves the structural strength and connection strength of the longitudinal beam 100.

[0064] In an optional embodiment, there are multiple support portions 12, one of which is used to connect the shotgun beam 200 and the main body plate 111, thereby improving the connection strength between the shotgun beam 200 and the main body plate 111.

[0065] In a further embodiment, the support portion 12 further includes a first support member 122 and a second support member 123, which are connected to both sides of the connecting plate 121 and are arranged opposite to each other along the third direction Z. The first support member 122 and the second support member 123 are respectively connected to the side plate 112.

[0066] like Figure 7 As shown, the first support member 122 and the second support member 123 are located on both sides of the third direction Z of the connecting plate 121, with the first support member 122 located above the second support member 123.

[0067] The first support member 122 and the second support member 123 are strip-shaped, sheet-shaped, plate-shaped or rod-shaped, etc. The first support member 122 is connected to the side plate 112 above the main body plate 111, and the second support member 123 is connected to the side plate 112 below the main body plate 111. The first support member 122 and the second support member 123 play a supporting and fixing role for the connecting plate 121, which helps to improve the connection strength between the connecting plate 121 and the connecting part 11 and prevent the connecting plate 121 from shaking or deforming.

[0068] For example, the first support member 122 and the second support member 123 are fixedly connected to the side plate 112 of the connecting part 11 by welding, bonding or other means.

[0069] In this embodiment, by providing the first support member 122 and the second support member 123, the connection strength between the connecting plate 121 and the connecting part 11 is improved, preventing the connecting plate 121 from shaking or deforming, and further improving the connection strength between the longitudinal beam 100 and the connecting structure 1.

[0070] In a further embodiment, the first support 122 and the second support 123 are respectively connected to the outer wall of the longitudinal beam 100.

[0071] Specifically, one end of the first support member 122 is connected to the side plate 112, and the other end is connected to the upper outer wall of the longitudinal beam 100; one end of the second support member 123 is connected to the side plate 112, and the other end is connected to the lower outer wall of the longitudinal beam 100. Under the action of the first support member 122 and the second support member 123, the connection strength between the connecting part 11 and the longitudinal beam 100 is further improved. The first support member 122 and the second support member 123 restrict the swaying and deformation of the longitudinal beam 100 in the first direction Y, which is beneficial to improving the structural strength and connection strength of the longitudinal beam 100.

[0072] For example, the first support member 122 and the second support member 123 are fixedly connected to the outer wall of the longitudinal beam 100 by welding, bonding or other means.

[0073] In this embodiment, by setting the first support member 122 and the second support member 123 to be connected to the outer wall of the longitudinal beam 100 respectively, the first support member 122 and the second support member 123 improve the connection strength between the connecting plate 121 and the connecting part 11, while also improving the connection strength between the connecting part 11 and the longitudinal beam 100, ensuring the overall strength of the front end of the longitudinal beam 100, which helps to reduce the penalty points of MPDB and improve the structural evaluation of small offset working conditions.

[0074] In a further embodiment, the first support member 122 and the second support member 123 are sheet-like or plate-like, and the first support member 122 and the second support member 123 are trapezoidal or triangular in shape. The support portion 12, the longitudinal beam 100 and the main body plate 111 surround and form a second cavity.

[0075] like Figure 7 and Figure 8 As shown, the first support member 122 and the second support member 123 are trapezoidal. One side of the first support member 122 overlaps with the side plate 112 above the connecting part 11, the other side of the first support member 122 is attached to the upper outer wall of the longitudinal beam 100, and another side of the first support member 122 overlaps with the upper end of the connecting plate 121. Similarly, one side of the second support member 123 overlaps with the side plate 112 below the connecting part 11, the other side of the second support member 123 is attached to the lower outer wall of the longitudinal beam 100, and another side of the second support member 123 overlaps with the lower end of the connecting plate 121.

[0076] With this arrangement, the first support member 122 covers the upper ends of the longitudinal beam 100, the main plate 111, and the connecting plate 121, and the second support member 123 covers the lower ends of the longitudinal beam 100, the main plate 111, and the connecting plate 121, thereby forming a second cavity by the first support member 122, the second support member 123, the connecting plate 121, the main plate 111, and the longitudinal beam 100.

[0077] For example, the second cavity is a sealed cavity.

[0078] In this embodiment, by setting the support part 12, the longitudinal beam 100 and the main plate 111 to form a second cavity, a stable triangular structure is formed, so that the first support member 122 and the second support member 123 simultaneously connect the longitudinal beam 100, the connecting part 11 and the connecting plate 121, which effectively disperses the external force and maintains the stability of the structure, ensures the overall strength of the front end of the longitudinal beam 100, helps to reduce the penalty points of MPDB and improve the structural evaluation of small offset working conditions.

[0079] In one specific embodiment, the edge of the connecting plate 121 is formed with a folded edge 121a, and the first support member 122 and the second support member 123 respectively cover the folded edge 121a and are connected to the folded edge 121a.

[0080] like Figure 7 As shown, the connecting plate 121 is rectangular, and each of the four edges of the connecting plate 121 has a folded edge 121a. The folded edge 121a at the upper end of the connecting plate 121 is connected to the first support member 122, the folded edge 121a at the lower end of the connecting plate 121 is connected to the second support member 123, the folded edge 121a at the left end of the connecting plate 121 is used to connect to the longitudinal beam 100, and the folded edge 121a at the right end of the connecting plate 121 is used to connect to the main plate 111.

[0081] In this embodiment, by setting the folded edge 121a, it is convenient to weld the connecting plate 121 and the first support member 122 and the second support member 123, which increases the welding area, enhances the load-bearing capacity of the weld, and improves the overall strength and structural stability of the front end of the longitudinal beam 100.

[0082] In one specific embodiment, the flange 113 has a connecting hole 113a for fasteners to pass through. Specifically, the connecting hole 113a is a through hole that extends through the flange 113 along the second direction X.

[0083] like Figure 3 As shown, the connecting structure 1 has four flanges 113, and at least two flanges 113 are provided with connecting holes 113a. Fasteners pass through the connecting holes 113a and are connected to the mounting plate 300, thus realizing a stable and reliable connection between the connecting structure 1 and the mounting plate 300.

[0084] For example, the flange 113 is provided with a plurality of connection holes 113a. Figure 3 As shown, the upper flange 113 and the lower flange 113 of the connecting structure 1 are respectively provided with three connecting holes 113a. The three connecting holes 113a are distributed at intervals along the first direction Y, which is beneficial to improving the connection strength between the connecting structure 1 and the mounting vertical plate 300 in the first direction Y.

[0085] For example, the connecting hole 113a is a threaded hole, and the fastener is a screw, bolt or other threaded fastener.

[0086] This application embodiment also provides a vehicle, including the connection structure 1 provided in any of the above embodiments, and further including longitudinal beams 100 and shotgun beams 200, the longitudinal beams 100 and shotgun beams 200 being distributed at intervals along a first direction Y, and both the longitudinal beams 100 and shotgun beams 200 being connected to the connection structure 1.

[0087] like Figure 9and Figure 10 As shown, the vehicle's longitudinal beam 100 and shotgun beam 200 extend along the second direction X and are spaced apart along the first direction Y. The front ends of the longitudinal beam 100 and the shotgun beam 200 are respectively connected to the connecting structure 1, realizing the overlap of the shotgun beam 200, the mounting vertical plate 300, and the longitudinal beam 100. This helps to disperse and transmit the collision force, improve the force transmission effect of the shotgun beam 200, and improve the structural evaluation under small offset conditions.

[0088] For example, the cross-section of the front end of the longitudinal beam 100 is approximately "U"-shaped. The front end of the longitudinal beam 100 has an opening on one side in its width direction (i.e., the first direction Y). The connecting part 11 can extend into the space enclosed by the longitudinal beam 100 along the second direction X, and the flange 113 can abut against the end of the longitudinal beam 100, thus limiting the longitudinal beam 100. Optionally, the three inner sidewalls of the longitudinal beam 100 abut against the side plate 112 on the same side, and the side plate 112 provides sufficient support for the longitudinal beam 100. Optionally, the inner sidewalls of the longitudinal beam 100 and the side plate 112 are connected by welding.

[0089] This configuration allows the connecting part 11 to support and reinforce the front end of the longitudinal beam 100, thereby increasing the connection strength between the longitudinal beam 100 and the connecting structure 1 in the first direction Y and / or the second direction X, and improving the connection stability and reliability of the longitudinal beam 100.

[0090] For example, the front end of the shotgun beam 200 is provided with multiple folded welding edges 201, which are attached to the side plate 112 or the main plate 111 so as to weld the front end of the shotgun beam 200 to the connecting part 11, ensuring that the shotgun beam 200 and the connecting part 11 have sufficient connection strength.

[0091] The vehicle provided in this application embodiment connects the longitudinal beam 100 and the connecting structure 1 by inserting the side plate 112 and the main plate 111 into the inner cavity of the longitudinal beam 100; at the same time, the shotgun beam 200 is connected to the connecting structure 1 through the side plate 112, and the mounting vertical plate 300 is connected to the connecting structure 1 through the flange 113. This connects the mounting vertical plate 300, the longitudinal beam 100, and the shotgun beam 200 together, ensuring the connection strength between the front end of the longitudinal beam 100 and the shotgun beam 200 and other parts of the vehicle body. It also ensures that the force transmission path of the vehicle has sufficient coverage and support strength in the Y direction, improves the energy transmission effect of the shotgun beam 200, fully utilizes the role of the shotgun beam 200 in MPDB and small offset conditions, reduces MPDB penalties, and improves the structural evaluation of small offset conditions.
