[0042] The sill beam assembly is the main beam structure on the left and right sides of the middle part of the vehicle. The sill beam assembly is arranged close to the vehicle chassis. The sill beam assembly is mainly used to cushion the impact of the vehicle door body and the outside. For example, when the vehicle is closing the door, the sill beam assembly will bear the lateral impact force of the door on the sill beam assembly; for another example, when the vehicle is hit by a pillar or a side collision, the sill beam assembly can become the main load-bearing structure on the side of the vehicle. Specifically, the sill beam assembly includes a structural beam, and the structural beam is the main load-bearing structure.

[0043] In the related technology, the structural beam extends a certain length along the length of the vehicle, and the two ends of the structural beam are assembled with the plate body in the sill beam assembly. The middle area of ​​the structural beam is in a suspended state, which causes the sill beam assembly to easily produce resonance and vibrating problems when the sill beam assembly is hit, resulting in poor user perception of refinement.

[0044] Therefore, the present application provides a threshold beam assembly 1110, wherein a side panel assembly 1111 (which may refer to a part of a side panel outer panel 1121 assembly) and a threshold beam assembly are arranged to form a receiving cavity 1115, a structural beam 11131 is arranged in the receiving cavity 1115, and the structural beam 11131 is supported by a plurality of first support frames 11132 arranged at intervals along the extended length of the structural beam 11131, and each first support frame 11132 is fixedly connected to the threshold beam by a first locking assembly 11133. The structure beam 11131 is mounted on the side panel assembly 1112 and is connected to the side panel assembly 1111 by the second locking assembly 1114, so that the structure beam 11131 is firmly connected to the side panel assembly 1111 and the threshold beam body 1112. The middle area of ​​the structure beam 11131 is supported by the first support frame 11132 and connected to the threshold beam body 1112, thereby improving the stability of the structure beam 11131. When the threshold beam assembly 1110 is collided, the threshold beam assembly 1110 is not prone to resonance and vibrating problems, which is beneficial to improving the user experience.

[0045] In order to make the objectives, technical solutions and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0046] See also Figure 1-3As shown, the embodiment of the present application provides a threshold beam assembly 1110, which includes a side panel assembly 1111, a threshold beam body 1112, a beam assembly 1113 and a second locking assembly 1114; the side panel assembly 1111 is extended along the vehicle length direction X; a threshold assembly groove 11121 is formed on the threshold beam body 1112, and the notch of the threshold assembly groove 11121 is extended along the vehicle length direction X, the side panel assembly 1111 is connected to the threshold beam body 1112, and is covered on the notch of the threshold assembly groove 11121, so as to jointly enclose a receiving cavity 1115 extending along the vehicle length direction X; the beam assembly 1113 includes a structural beam 11131, a first The support frame 11132 and the first locking assembly 11133, the structural beam 11131 extends along the vehicle length direction X and is accommodated in the accommodating cavity 1115, and a structural cavity 111311 is formed in the structural beam 11131; the first support frame 11132 and the first locking assembly 11133 are each provided with a plurality of first support frames 11132, each of which is connected to the structural beam 11131 and is arranged between the two extending ends of the structural beam 11131 along the vehicle length direction X at intervals, and each first support frame 11132 is connected to the door sill beam body 1112 via the first locking assembly 11133; the second locking assembly 1114 is connected between the structural beam 11131 and the side panel assembly 1111.

[0047] Specifically, the vehicle includes a frame, which can also be referred to as a body assembly 1000. The body assembly 1000 is a frame structure. The body assembly 1000 includes a structure located at the bottom of the vehicle and a structure located at the side of the vehicle. The structure at the side of the frame is generally referred to as a side panel assembly 1100. The side panel assembly 1100 is used to install components such as doors. The side panel assembly 1100 generally includes a side panel outer plate 1121 and a side panel reinforcement plate 1122. The side panel outer plate 1121 and the side panel reinforcement plate 1122 can be assembled by welding, riveting, bolting, etc. When the door is closed, the door and other components can be connected to the side panel assembly 1100. Collision, the side panel assembly 1100 includes a side panel assembly 1111, and the side panel assembly 1111 is located near the bottom of the side panel assembly 1100; the structure at the bottom of the body assembly 1000 is generally referred to as the lower body assembly 1200, and the lower body assembly 1200 can also be understood as a chassis assembly of the frame, and the chassis structure includes various plate bodies and rod body structures, etc.; the rocker beam body 1112 is usually arranged on the side of the lower body assembly 1200, or the rocker beam body 1112 can also be considered as a part of the lower body assembly 1200, then it can be known that the rocker beam body 1112 is located near the bottom of the side panel assembly 1100.

[0048] The vehicle has a vehicle length direction X, a vehicle width direction X and a vehicle height direction Z. The vehicle length direction X is the direction between the front and rear of the vehicle, the vehicle width direction X is the direction between the two sides of the vehicle, and the vehicle width direction X can be considered to be perpendicular to the vehicle length direction X. The vehicle height direction Z is the direction between the top and the bottom of the vehicle, and the vehicle height direction Z is perpendicular to the vehicle length direction X and the vehicle width direction X. For example, when the vehicle is placed on a horizontal ground, the vehicle height direction Z is the vertical direction, the vehicle length direction X and the vehicle width direction X are both parallel to the horizontal direction, and the vehicle length direction X is perpendicular to the vehicle width direction X.

[0049] The side panel assembly 1111 is connected to the rocker beam body 1112 to form a accommodating cavity 1115. Specifically, the side panel outer panel assembly 1120 may include a plurality of plate-like structures, and the side panel assembly 1111 is formed on the side panel outer panel assembly 1120. The side panel assembly 1111 may be in the shape of a flat plate or a curved plate. For example, the cross-sectional profile of the side panel assembly 1111 perpendicular to the vehicle length direction X may be groove-shaped, that is, an inner recess may be formed on the side panel assembly 1111, and along the vehicle width direction X, the inner recess is concave inwardly toward the direction away from the rocker beam body 1112 to form a groove; along the vehicle length direction X, the side panel assembly 1111 extends a preset length along the vehicle length direction X.

[0050] The rocker beam body 1112 may be a plate-shaped structure, such as a stamped plate-shaped member. The rocker beam body 1112 extends along the vehicle length direction X. In the vehicle width direction X, the rocker beam body 1112 and the side panel assembly 1111 are arranged opposite to each other. A threshold assembly groove 11121 is formed on the threshold beam body 1112. The threshold assembly groove 11121 is concave on the threshold beam body 1112 in a direction away from the side panel assembly 1111. The notch of the threshold assembly groove 11121 extends along the vehicle length direction X. The notch of the threshold assembly groove 11121 is arranged opposite to the side panel assembly 1111. The side panel assembly 1111 is connected to the threshold beam body 1112, so that the side panel assembly 1111 covers the notch of the threshold assembly groove 11121. The side panel assembly 1111 and the threshold beam body 1112 are jointly arranged to form a receiving cavity 1115. It can be known that the receiving cavity 1115 is extended along the vehicle length direction X. The rocker beam body 1112 may have an area at the lower end of the front A-pillar of the vehicle connected to an area at the wheel arch of the rear end of the vehicle, thereby effectively improving the rigidity and strength of the rocker beam assembly 1110 and reducing the risk of bending of the rocker beam assembly 1110 after a head-on collision or a small offset collision of the vehicle.

[0051] The beam assembly 1113 is accommodated in the accommodating cavity 1115. Specifically, the beam assembly 1113 includes a structural beam 11131, a first support frame 11132 and a first locking assembly 11133. The structural beam 11131 is extended along the vehicle length direction X and is inserted in the accommodating cavity 1115 in the same direction. The structural beam 11131 can adopt an aluminum profile structure with a uniform cross section and is prepared by an aluminum extrusion process. The interior of the structural beam 11131 forms a structural cavity 111311, and the structural cavity 111311 can be provided with one or more. It can be seen that the structural beam 11131 can adopt a hollow beam structure. In a collision, the structural beam 11131 is the main load-bearing component, and the stability of the structural beam 11131 is crucial to the collision process.

[0052] The first support frame 11132 is connected between the structural beam 11131 and the threshold beam body 1112, so as to connect the structural beam 11131 to the threshold beam body 1112, so as to fix the structural beam 11131. A plurality of first support frames 11132 are provided, and the plurality of first support frames 11132 are arranged at intervals along the extension direction of the structural beam 11131, so as to support the structural beam 11131 over the entire extension length. That is to say, the first support frames 11132 are respectively provided at the two extension ends of the structural beam 11131, and the first support frame 11132 is also provided at the middle position between the two extension ends, and a plurality of first support frames 11132 can be provided at the middle position, so as to support the structural beam 11131 over the entire extension length, thereby improving the connection strength of the structural beam 11131 and improving the stability of the structural beam 11131.

[0053] There are also multiple first locking components 11133, for example, 3-7 first locking components 11133 are used to connect between the first support frame 11132 and the threshold beam body 1112 to fix the first support frame 11132 and the threshold beam body 1112. One or more first locking components 11133 can be set between a first support frame 11132 and the threshold beam body 1112; the first locking component 11133 can adopt a bolt component, and threaded holes or through holes can be opened at corresponding positions of the corresponding first support frame 11132 and the threshold beam body 1112. The bolt component is connected in the threaded hole or through hole, so as to lock the first support frame 11132 and the threshold beam body 1112; wherein the bolt component may include a flat head rivet nut, thereby providing a glue coating surface between the structural beam 11131 and the threshold beam body 1112, so that structural glue can be coated between the connecting surface of the structural beam 11131 and the threshold beam body 1112.

[0054] The second locking assembly 1114 may be provided with one or more, for example, 1-7, and the plurality of locking assemblies may be arranged at intervals along the extension length direction of the structural beam 11131. The second locking assembly 1114 is used to connect the structural beam 11131 and the side panel assembly 1111 to fix the structural beam 11131 and the side panel assembly 1111. The second locking assembly 1114 may adopt a bolt assembly, and threaded holes or through holes may be provided at corresponding positions of the corresponding structural beam 11131 and the side panel assembly 1111, and the bolt assembly is passed through the threaded holes or through holes, so as to lock the structural beam 11131 and the side panel assembly 1111.

[0055] In this example, when the vehicle is hit laterally, the impact force is located on the side of the side panel assembly 1111 facing away from the rocker beam 1112, and the direction of the impact force may be toward the side panel assembly 1111 in a direction parallel to the vehicle width direction X or in a direction forming an angle with the vehicle width direction X; when the vehicle is hit longitudinally, the impact force is along the vehicle length direction X. For the present sill beam assembly 1110, a accommodating cavity 1115 is formed between the side enclosure assembly 1111 and the sill beam body 1112, and the accommodating cavity 1115 can buffer both longitudinal and lateral impact forces, and is particularly effective in buffering lateral impacts. The buffering effect of the cavity can absorb the impact energy and disperse it into the side enclosure assembly 1111 and the sill beam body 1112, so as to reduce the impact of the impact or shock force on the sill beam assembly 1110. In addition, a structural cavity 111311 is also provided in the structural beam 11131, and the structural cavity 111311 also has a buffering effect on the impact force. The impact force is transmitted to the structural beam 11131, and the structural cavity 111311 absorbs and disperses the impact force, thereby playing a buffering role, reducing the lateral intrusion amount, and thus better protecting the battery pack and the cockpit system.

[0056] Furthermore, in the present embodiment, by providing a plurality of first support frames 11132 and a plurality of first locking components 11133, the structural beam 11131 is fixedly connected to the sill beam body 1112, and the plurality of first support frames 11132 are arranged at intervals along the extension length of the structural beam 11131, so that the two extension ends of the structural beam 11131 and the middle area between the two extension ends are supported by the first support frames 11132, which is beneficial to reducing the resonance and vibrato problems of the structural beam 11131 during a collision; in addition, the structural beam 11131 is also connected to the side panel assembly 1111 through the second locking component 1114, so that the stability of the structural beam 11131 is enhanced. During a collision, the structural beam 11131 can further reduce the vibration relative to the side panel assembly 1111 and the sill beam body 1112, which is beneficial to reducing the risk of resonance and vibrato and improving the reliability of the sill beam.

[0057] In one embodiment, referring to Figure 3-5 As shown, the structural cavity 111311 includes a plurality of first sub-structural cavities 111311a, and the plurality of first sub-structural cavities 111311a are arranged at intervals along the vehicle width direction X.

[0058] Specifically, the structural beam 11131 can adopt a hollow beam structure, and the hollow cavity is the structural cavity 111311. A plurality of rib plate structures are arranged in the structural cavity 111311. The rib plate structures are connected to the cavity wall of the structural cavity 111311, thereby dividing the structural cavity 111311 into a plurality of first sub-structural cavities 111311a. The number of first sub-structural cavities 111311a can be a natural number, for example, 2, 3, 4, 5, etc.

[0059] In this embodiment, along the vehicle length direction X, each first substructure cavity 111311a extends to form a preset length, and along the vehicle width direction X, multiple first substructure cavities 111311a are arranged at intervals. It can also be understood that multiple first substructure cavities 111311a are stacked in the vehicle width direction X. During a lateral impact, each first substructure cavity 111311a can absorb and disperse the impact force, thereby helping to enhance the cushioning effect. In addition, the provision of multiple first substructure cavities 111311a can also enhance the overall structural stability of the structural beam 11131.

[0060] In one embodiment, referring to Figure 3-5 As shown, the structural cavity 111311 also includes one or more second sub-structural cavities 111311b, and the second sub-structural cavities 111311b are all located on the side of the first sub-structural cavity 111311a close to the top of the vehicle. When the structural cavity 111311 includes multiple second sub-structural cavities 111311b, the multiple second sub-structural cavities 111311b are arranged at intervals along the vehicle width direction X.

[0061] Specifically, the second structural cavity 111311 is located on one side of the first sub-structural cavity 111311a close to the top of the vehicle. For example, if the vehicle is placed horizontally, the second structural cavity 111311 is located above the first sub-structural cavity 111311a. The combination of the first sub-structural cavity 111311a and the second structural cavity 111311 forms a double-layer cavity structure, so that when the side of the vehicle is subjected to a horizontally inclined downward impact force or a vertical impact force, a multi-layer cavity can be formed along the impact direction, which is conducive to multi-layer absorption and diffusion of the impact force.

[0062] The number of second substructure cavities 111311b can be a natural number, for example, 1, 2, 3, 4, 5, etc., and multiple second substructure cavities 111311b can be arranged at intervals in the vehicle width direction X. The number of second substructure cavities 111311b can be the same as or different from the number of first substructure cavities 111311a. When the number of second substructure cavities 111311b is the same as the number of first substructure cavities 111311a, each second substructure cavity 111311b can be arranged one-to-one with each first substructure cavity 111311a below.

[0063] In this embodiment, the combination of the first substructure cavity 111311a and the second structure cavity 111311 forms a double-layer cavity structure, so that when the side of the vehicle is subjected to a horizontally inclined upward impact force or a vertical impact force, a multi-layer cavity can be formed along the impact direction, which is beneficial to the multi-layer absorption and diffusion of the impact force.

[0064] In one embodiment, referring to Figure 3-5 As shown, the structural cavity 111311 also includes one or more third sub-structural cavities 111311c, and the third sub-structural cavities 111311c are all located on the side of the first sub-structural cavity 111311a close to the bottom of the vehicle. When the structural cavity 111311 includes multiple third sub-structural cavities 111311c, the multiple third sub-structural cavities 111311c are arranged at intervals along the vehicle width direction X.

[0065] The third structure cavity 111311 is located on one side of the first substructure cavity 111311a close to the bottom of the vehicle. For example, if the vehicle is placed horizontally, the third structure cavity 111311 is located below the first substructure cavity 111311a. The combination of the first substructure cavity 111311a and the third structure cavity 111311 forms a double-layer cavity structure, so that when the side of the vehicle is subjected to a horizontally inclined upward impact force or a vertical impact force, a multi-layer cavity can be formed along the impact direction, which is conducive to multi-layer absorption and diffusion of the impact force.

[0066] The number of third substructure cavities 111311c can be a natural number, for example, 1, 2, 3, 4, 5, etc., and multiple third substructure cavities 111311c can be arranged at intervals in the vehicle width direction X. The number of third substructure cavities 111311c can be the same as or different from the number of first substructure cavities 111311a. When the number of third substructure cavities 111311c is the same as the number of first substructure cavities 111311a, each third substructure cavity 111311c can be arranged one-to-one with each first substructure cavity 111311a above.

[0067] For example, there are three first substructure cavities 111311a, three second substructure cavities 111311b, and two third substructure cavities 111311c. The three second substructure cavities 111311b and the three first substructure cavities 111311a are arranged one by one along the vehicle height direction Z (or vertical direction), and the rib plate structure can be provided with 11.

[0068] In this embodiment, the combination of the first substructure cavity 111311a, the second substructure cavity 111311b and the third structure cavity 111311 forms a three-layer cavity structure, so that when the side of the vehicle is subjected to a horizontally inclined upward or horizontally inclined downward impact force or a vertical impact force, a multi-layer cavity can be formed along the impact direction, which is beneficial to the multi-layer absorption and diffusion of the impact force.

[0069] In one embodiment, referring to Figure 3-5 As shown, the structural beam 11131 includes a plurality of structural walls, which are arranged around an axis parallel to the vehicle length direction X to form a structural cavity 111311, and the plurality of structural walls include at least a first structural wall 111312 and a second structural wall 111313 that are adjacent and vertically connected, wherein the first structural wall 111312 is parallel to the bottom of the door sill assembly groove 11121 (i.e., the first groove bottom 111211 described below), and the first structural wall 111312 is located on the side of the structural beam 11131 close to the bottom of the vehicle; the first support frame 11132 is respectively connected to the first structural wall 111312 and the second structural wall 111313.

[0070] Specifically, the structural wall is the side wall of the structural beam 11131, and each structural wall is extended along the vehicle length direction X. Each structural wall can be in the shape of a sheet (or plate); multiple structural walls are formed by surrounding an axis in the vehicle length direction X, and the axis is the central axis or extended axis of the structural beam 11131.

[0071] Reference Figure 3-5As shown, the structural beam 11131 includes 6 structural walls, among which there are at least two adjacent and vertical structural walls. For the sake of description, the two structural walls are defined as a first structural wall 111312 and a second structural wall 111313, respectively. Therefore, the first structural wall 111312 is parallel to the bottom of the threshold assembly groove 11121, and the bottom of the threshold assembly groove 11121 can be parallel to the vehicle height direction Z, then the first structural wall 111312 can be arranged parallel to (or along) the vehicle height direction Z; the second structural wall 111313 is located on the side of the structural beam 11131 close to the bottom of the vehicle. It can be seen that the second structural wall 111313 is arranged parallel to the vehicle width direction X (or parallel to the horizontal direction). The first structural wall 111312 and the second structural wall 111313 are vertically connected, so that the structural beam 11131 forms two vertically connected connection surfaces, and the first structural wall 111312 and the second structural wall 111313 are located at a position of the structural beam 11131 close to the bottom surface of the groove and close to the bottom of the vehicle; the first support frame 11132 is respectively connected to the first structural wall 111312 and the second structural wall 111313. It can be understood that the first support frame 11132 is connected to the bottom position of the groove of the structural beam 11131 close to the bottom of the vehicle and close to the threshold assembly groove 11121. It can be seen that the installation position of the first support frame 11132 is back to the side panel assembly 1111, that is, the installation position of the first support frame 11132 is back to the lateral impact force, which is beneficial to improve the support stability of the structural beam 11131.

[0072] A plurality of leakage holes can be opened on the structural beam 11131 including six structural walls and a rib plate structure to ensure smooth flow of the electrophoretic liquid in the accommodating cavity 1115 and sufficient electrophoresis during the electrophoretic coating process, so as to ensure that the thickness of the electrophoretic paint film of the sheet metal in the accommodating cavity 1115 meets the anti-corrosion target requirements of the vehicle.

[0073] In this embodiment, the first support frame 11132 is connected to two adjacent and perpendicular structural walls of the structural beam 11131, and the first support frame 11132 is connected to a position of the structural beam 11131 close to the bottom of the vehicle and the bottom of the threshold assembly groove 11121, so that the first support frame 11132 can face away from the lateral impact force, thereby improving the stability of the first support frame 11132 supporting the structural beam 11131, thereby helping to reduce the risk of resonance and vibrato of the structural beam 11131 and improving the reliability of the threshold beam.

[0074] In one embodiment, referring to Figure 1-5As shown, a side panel assembly groove 11111 is formed on the side panel assembly body 1111, the groove opening of the side panel assembly groove 11111 is arranged toward the structural beam 11131, and the groove opening of the side panel assembly groove 11111 is extended along the vehicle length direction X, the groove bottom of the side panel assembly groove 11111 (i.e., the second groove bottom 11112 described below) is arranged in parallel with the groove bottom of the door sill assembly groove 11121 (i.e., the first groove bottom 111211 described below), and the groove walls of the side panel assembly groove 11111 on both sides along the vehicle length direction X extend from the groove bottom toward the groove bottom away from the groove bottom. The plurality of structural walls are arranged gradually expanding in direction; the plurality of structural walls include at least a third structural wall 111314 and two fourth structural wall bodies 111315 connected to the third structural wall 111314; the third structural wall 111314 is arranged opposite to and parallel to the first structural wall 111312; the third structural wall 111314 is arranged opposite to and parallel to the bottom of the side enclosure assembly groove 11111; the two fourth structural walls 111315 are arranged opposite to and parallel to the two groove walls of the side enclosure assembly groove 11111, respectively.

[0075] Specifically, the side panel assembly 1111 can be prepared by a plate-like structure, the side panel assembly groove 11111 can be a stamped groove structure, the side panel assembly 1111 is arranged opposite to the sill beam body 1112, so the side panel assembly groove 11111 is formed on one side of the side panel assembly 1111 facing the sill beam body 1112. The side panel assembly groove 11111 has a groove bottom and a groove wall. For the convenience of description, the side panel assembly groove 11111 is defined as having a groove bottom as the second groove bottom 11112, and a groove wall as the second groove wall 11113. The groove bottom of the sill assembly groove 11121 is the first groove bottom 111211, and the groove wall is the first groove wall 111212. Then, the notch of the side panel assembly groove 11111 is opposite to the notch of the sill assembly groove 11121, so as to enclose and form the accommodating cavity 1115, and the second groove bottom 11112 is parallel to the first groove bottom 111211.

[0076] The two second groove walls 11113 are respectively connected to the second groove bottom 11112, and the two second groove walls 11113 are gradually expanded from the position connected to the second groove bottom 11112 toward the direction away from the second groove bottom 11112, that is, the second groove wall 11113 and the second groove bottom 11112 are set at an obtuse angle greater than 90°.

Among the six structural walls, the thickness of the upper fourth structural wall 111315 and the first structural wall 111312 are the thickest, which can be 3.5 mm. The thickness of the lower fourth structural wall 111315 and the second structural wall 111313 can be relatively reduced, for example, to 3.0 mm. The thickness of the rib plate structure can be 3.5 mm, 3.0 mm or 2.5 mm, etc., and can be adaptively designed according to the different sizes of the stress positions of the structural beam 11131.

[0078] In this example, a side panel assembly groove 11111 is formed on the side panel assembly 1111, which helps to improve the structural rigidity and strength of the side panel assembly 1111, and makes the structural wall of the structural beam 11131 respectively relative to and matched with the groove bottom and groove wall of the side panel assembly groove 11111, which helps to improve the matching degree of the relative position of the structural beam 11131 and the side panel assembly 1111, reduce interference problems during collision, and improve the stability of the structure.
