Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of automobile parts, and particularly to a reinforcing support, a rocker, a body side and an automobile. BACKGROUND

[0002] The body side is generally composed of a rocker, a pillar and a side wall panel, and is usually designed as a hollow structure in order to realize lightweight design and reduce material cost. In some vehicle models, the rocker itself is the bottom structure of the body side, and the inner cavity surrounded by the inner and outer rockers is the bottom cavity of the body side. In other vehicle models, the rocker is connected to the pillar interface at the bottom of the surrounding pillar, and the pillar interface at the bottom of the surrounding pillar and the rocker together form the bottom structure of the body side. Accordingly, the sidewall of the bottom cavity of the body side includes not only the sidewall of the rocker, but also the sidewall of the pillar interface. During daily use, the vehicle needs to be lifted by a lifting machine due to vehicle maintenance or battery replacement, etc. Therefore, the bottom of the body side is generally provided with a lifting seat for contacting the lifting machine. In order to prevent the lifting seat from being exposed, the lifting seat is usually designed at the bottom of the inner rocker (not the outer rocker), and two lifting machines are arranged on the left and right inner rockers. In this way, the four lifting machines arranged in a rectangular shape can lift the vehicle.

[0003] In some vehicle models, the lifting seat at the bottom of the inner rocker cannot be strictly guaranteed to be at the transverse center of the inner rocker. In this case, the lifting force will generate a moment perpendicular to the ground line (lifting moment), and the fulcrum of the lifting moment is the transverse center of the inner rocker. If the distance between the lifting seat and the transverse center of the inner rocker is greater, the arm of the lifting moment will be larger, and the lifting moment will also be larger. In the case of large lifting moment, the inner rocker and even the bottom structure of the body side will yield due to unbalanced force, resulting in deformation, cracking or even breaking. It may also cause the rivets or screws on the inner rocker and even the bottom structure of the body side to loosen or fall off. If the inner rocker and even the bottom structure of the body side deforms or breaks during lifting, it may also cause the paint surface of the vehicle to peel off, and even the metal parts exposed to the air may rust. Deformation of the inner rocker and even the bottom structure of the body side may also cause the vehicle door to be unable to open and close normally. SUMMARY

[0004] The utility model aims to solve at least one of the above technical problems.

[0005] To solve the above problems, the utility model provides a kind of reinforced support, the reinforced support is used to set in the bottom cavity of vehicle body side wall, the top of the reinforced support is connected with the inner door sill beam top wall of the inner door sill beam and / or with the sidewall of the column butt joint part of peripheral column, the bottom of the reinforced support at least has first installation part and second installation part, the first installation part and the second installation part are connected at different horizontal positions of the inner door sill beam bottom wall of the inner door sill beam respectively.

DETAILED DESCRIPTION

[0032] In order to make the above-mentioned purpose, features and advantages of the utility model more obvious and easy to understand, the specific embodiments of the utility model are described in detail below with reference to the drawings.

[0033] In the description of the utility model, it is understood that the orientation or position relationship indicated by the terms "upper", "lower", "left", "right", "front", "rear" and the like is based on the orientation or position relationship shown in the drawings, and is only for the convenience of describing the utility model and simplifying the description, and therefore cannot be understood as a limitation on the utility model.

[0034] Moreover, the Z-axis in the drawings represents the vertical direction, that is, the up-down direction, and the positive direction of the Z-axis represents up and the negative direction of the Z-axis represents down; the Y-axis in the drawings represents the horizontal direction, that is, the left-right direction, and the positive direction of the Y-axis represents left and the negative direction of the Y-axis represents right; the X-axis in the drawings represents the longitudinal direction, that is, the front-rear direction, and the positive direction of the X-axis represents front and the negative direction of the X-axis represents rear. It should be noted that the meanings of the aforementioned Z-axis, Y-axis and X-axis are only for the convenience of describing the utility model and simplifying the description, and therefore cannot be understood as a limitation on the utility model.

[0035] Among them, Figure 1 , Figure 5 , Figure 7 and Figure 9 In order to show the reinforcing support 1 installed in the bottom cavity, the outer rocker beam in the rocker beam is not shown, and only the inner rocker beam in the rocker beam is shown, and the shown inner rocker beam is shown with the inner rocker beam on the right side of the automobile as an example, and the positive and negative directions of the transverse direction (Y-axis direction) involved are shown with the orientation of the inner rocker beam on the right side of the automobile.

[0036] Referring to Figures 1-4The utility model discloses a kind of reinforced supports 1, the reinforced support 1 is used to be arranged in the bottom cavity of vehicle body side wall, the top of the reinforced support 1 is connected with the inner door sill beam top wall 32 of the inner door sill beam 3 and / or with the side wall of the column butt joint portion 41 of peripheral column 4, the bottom of the reinforced support 1 at least has first mounting portion 11 and second mounting portion 21, the first mounting portion 11 and the second mounting portion 21 are connected at different horizontal positions of the inner door sill beam bottom wall 31 of the inner door sill beam 3 respectively.

[0037] In the embodiment, the reinforced support 1 is arranged in the bottom cavity of the vehicle body side wall. Since the top of the reinforced support 1 is connected with the top wall of the bottom cavity (i.e., connected with the inner door sill beam top wall 32 and / or the side wall of the column butt joint portion 41), the first mounting portion 11 and the second mounting portion 21 of the bottom of the reinforced support 1 are respectively connected with the inner door sill beam bottom wall 31. Therefore, the reinforced support 1 can increase the rigidity of the inner door sill beam in the vertical direction, and to a certain extent, prevent the deformation of the bottom structure of the inner door sill beam and even the vehicle body side wall under the action of lifting force. In addition, since the first mounting portion 11 and the second mounting portion 21 are specifically mounted at different horizontal positions of the inner door sill beam bottom wall 31, at least one of the first mounting portion 11 and the second mounting portion 21 deviates from the horizontal center of the inner door sill beam bottom wall 31. In this way, when the lifting force of the lifting machine acts on the position deviating from the horizontal center of the inner door sill beam bottom wall 31, if the one of the first mounting portion 11 and the second mounting portion 21 deviating from the horizontal center of the inner door sill beam bottom wall 31 is located directly above the lifting force, the second mounting portion 21 can offset at least part of the lifting moment at this time, reducing the risk of torsional deformation of the inner door sill beam 3. If the one of the first mounting portion 11 and the second mounting portion 21 deviating from the horizontal center of the inner door sill beam bottom wall 31 is not directly above the lifting force, it can serve as the fulcrum of the lifting moment, so that the force arm of the lifting moment will not be too large, which can effectively prevent the inner door sill beam 3 from torsional deformation, cracking or even breaking, and improve the stability of the inner door sill beam and even the bottom structure of the vehicle body side wall.

[0038] It should be noted that in some vehicle models, the door sill beam itself is the bottom structure of the vehicle body side wall, and the inner cavity surrounded by the inner and outer door sill beams is the bottom cavity of the vehicle body side wall. At this time, the top of the reinforced support 1 is specifically connected to the inner door sill beam top wall 32, and the first mounting portion 11 and the second mounting portion 21 of the bottom of the reinforced support 1 are respectively connected to the inner door sill beam bottom wall 31.

[0039] In some other vehicle models, the rocker beam communicates with the pillar butt joint 41 at the bottom of the peripheral pillar 4 (for example, the A pillar), and the rocker beam and the pillar butt joint 41 jointly form the bottom structure of the body side. Accordingly, the inner and outer rocker beams and the pillar butt joint 41 jointly form the bottom cavity of the body side. In this case, the first mounting portion 11 and the second mounting portion 21 at the bottom of the reinforcing bracket 1 are connected to the bottom wall 31 of the inner rocker beam, but the top of the reinforcing bracket 1 can be connected to the side wall of the pillar butt joint 41 or / and the top wall 32 of the inner rocker beam. For example, as shown in Figs. Figures 1-2 and 5-10, the top of the reinforcing bracket 1 is connected to the side wall of the pillar butt joint 41. For ease of description, the "side wall of the pillar butt joint 41 and / or the top wall 32 of the inner rocker beam" connected to the top of the reinforcing bracket 1 can be collectively referred to as the top wall of the bottom cavity hereinafter.

[0040] Optionally, referring to Fig. Figures 1-4 , the first mounting portion 11 is in a plate structure, and at least one end thereof in the longitudinal direction (X-axis direction) is provided with a first side plate 12 bent upward relative to the first mounting portion 11; the first side plate 12 is connected to the top wall 32 of the inner rocker beam or the side wall of the pillar butt joint 41, and one end of the first side plate 12 in the transverse direction (Y-axis direction) is provided with a second side plate 22 bent relative to the first side plate 12, and the bottom end of the second side plate 22 is provided with the second mounting portion 21 bent relative to the second side plate 22.

[0041] In this embodiment, the first mounting portion 11 and the second mounting portion 21 are both in a plate structure, and at least one end of the front and rear ends of the first mounting portion 11 in a plate structure is provided with a first side plate 12 bent upward, and one end of the first side plate 12 in the transverse direction, for example, the right end of the first side plate 12 is provided with a second side plate 22 bent upward, and the bottom end of the second side plate 22 is provided with a second mounting portion 21 bent. The second mounting portion is also in a plate structure, so that by designing the first mounting portion 11 and the second mounting portion 21 to be in a plate structure, not only is the integral molding of the entire reinforcing bracket 1 facilitated, but also the connection area of the first mounting portion 11, the second mounting portion 21 and the bottom wall 31 of the inner rocker beam is increased, and the stability during force transmission is improved.

[0042] In addition, since the first mounting portion 11 is connected to the top wall of the bottom cavity via the vertical first side panel 12, and the second mounting portion 21 is connected to the top wall of the bottom cavity via the second side panel 22 and the first side panel 12, the entire reinforcing bracket 1 can have at least two force transmission paths for the lifting force. The first force transmission path is: first mounting portion 11 → first side panel 12 → top wall of the bottom cavity; the second force transmission path is: second mounting portion 21 → second side panel 22 → first side panel 12 → top wall of the bottom cavity. In this way, the bottom wall 31 of the inner sill beam can transmit the lifting force upward from its different lateral positions, thereby dispersing the lifting force and avoiding excessive stress concentration at the position of the bottom wall 31 of the inner sill beam corresponding to the lift.

[0043] Alternatively, see Figures 1-4 and Figures 7-8 The top end of the first side panel 12 is bent to form a first flange 13, and the first flange 13 is adhered to and connected to the top wall 32 of the inner sill beam or the side wall of the pillar docking portion 41; and / or, the end of the first side panel 12 away from the second side panel 22 is bent to form a second flange 14, and the second flange 14 is adhered to and connected to the inner sill beam transverse inner side wall 33 of the inner sill beam 3 or the side wall of the pillar docking portion 41.

[0044] For the convenience of description, the "lateral inner wall 33 of the inner sill beam or the side wall of the pillar docking portion 41" connected to the second flange 14 can be collectively referred to as the lateral inner wall of the bottom cavity.

[0045] In this embodiment, the top end of the first side panel 12 is connected to the top wall of the bottom cavity through the first flange 13, thereby increasing the connection area and force transmission area between the reinforcing bracket 1 and the top wall of the bottom cavity, and improving the stability during force transmission; in addition, the lateral inner side of the first side panel 12 is also connected to the lateral inner wall of the bottom cavity through the second flange 14 to ensure the stability of the installation of the reinforcing bracket 1 and prevent the reinforcing bracket 1 from shaking.

[0046] Among them, see Figure 2 and Figure 8 The side wall connecting the pillar docking portion 41 and the inner sill beam top wall 32 can be a non-planar wall. The non-planar portion includes a horizontal wall and an arcuate wall that bends upward relative to the horizontal wall. The inner sill beam top wall 32 is connected to the vertical side walls of the surrounding pillars 4 in sequence through the horizontal wall and the arcuate wall. The first flange 13 is connected to the side wall of the pillar docking portion 41, which means that the first flange 13 can be attached to and connected to the horizontal wall or the arcuate wall of the pillar docking portion 41. The side wall connecting the pillar docking portion 41 and the inner lateral side wall 33 of the inner sill beam is a vertical wall. The second flange 14 is connected to the side wall of the pillar docking portion 41, which means that the second flange 14 can be connected to the vertical wall.

[0047] Of course, in other embodiments, the first flange 13 can also be connected with the inner threshold beam top wall 32, and the second flange 14 is connected with the inner threshold beam transverse inner side wall 33.

[0048] Specifically, referring to Figures 3-4 Since the reinforcing bracket 1 is an integral structure formed by bending, it can be understood that there is a fillet portion between any two parts, that is, there is a first fillet transition 51 between the first flange 13 and the first side plate 12, a second fillet transition 52 between the first mounting portion 11 and the first side plate 12, a third fillet transition 53 between the first side plate 12 and the second side plate 22, a fourth fillet transition 54 between the second side plate 22 and the second mounting portion 21, and a fifth fillet transition 55 between the first side plate 12 and the second flange 14. In this way, by providing a fillet transition at each bending position, the reinforcing bracket 1 can not be too stress concentrated at each bending position, thereby preventing the reinforcing bracket 1 from being broken at the bending position and ensuring the effectiveness and stability of the lifting force transmission.

[0049] Optionally, referring to Figures 1-4 and Figures 7-8 , the first mounting portion 11 is provided with the first side plate 12 at both ends in the longitudinal direction, both of the first side plates 12 are provided with the second side plate 22 at one end in the transverse direction, the bottom ends of both of the second side plates 22 are provided with the second mounting portion 21, and both of the second side plates 22 are connected, and both of the second mounting portions 21 are connected.

[0050] In the embodiment, the front and rear ends of the plate-shaped first mounting portion 11 are both bent upward to form the first side plate 12, both of the first side plates 12 are bent at the right end shown in the figure to form the second side plate 22, the bottom ends of both of the second side plates 22 are bent to form the plate-shaped second mounting portion 21, and both of the second side plates 22 are connected, and both of the second mounting portions 21 are connected. In this way, in the two aforementioned transmission paths, in the first transmission path, part of the lifting force can be transmitted to the two first side plates 12 through the first mounting portion 11, and in the second transmission path, part of the lifting force can be transmitted from the two second mounting portions 21 to the corresponding first side plates 12 through the corresponding second side plates 22, thereby realizing more refined transmission paths and having more advantages in stabilizing the inner threshold beam 3 and the surrounding components. After the two second side plates 22 are connected and the two second mounting portions 21 are connected, firstly, the stability of the entire reinforcing bracket 1 can be ensured to be stronger, and secondly, in the transmission process, the load on the two second mounting portions 21 can be transmitted and shared with each other, and the load on the two second side plates 22 can also be transmitted and shared with each other, thereby achieving better transmission effect.

[0051] In other embodiments, the first flange 13 at the rear first side plate 12 can be connected with the inner rocker beam top wall 32, and the first flange 13 at the front first side plate 12 can be connected with the side wall of the column abutting portion 41, that is, the top of the reinforcing support 1 is connected with the inner rocker beam top wall 32 of the inner rocker beam 3 and the side wall of the column abutting portion 41 of the surrounding column 4; correspondingly, the second flange 14 at the rear first side plate 12 can be connected with the inner rocker beam transverse inner side wall 33, and the second flange 14 at the front first side plate 12 can be connected with the side wall of the column abutting portion 41.

[0052] Optionally, referring to Figures 1-4 and Figures 7-8 , the two second side plates 22 are partially overlapped, and the two second mounting portions 21 are partially overlapped.

[0053] In this embodiment, the two second side plates 22 are partially overlapped, and correspondingly, the two second mounting portions 21 are also partially overlapped, so that the reinforcing support 1 can further improve the rigidity of the inner rocker beam bottom wall 31 at the corresponding transverse position of the second side plate 22 and the second mounting portion 21. In addition, after the two second side plates 22 are partially overlapped, they can be fixed by multi-position spot welding to avoid cracking and separation between the two second side plates 22 during vertical load transmission. Similarly, after the two second mounting portions 21 are partially overlapped, they can also be fixed to the inner rocker beam bottom wall 31 by spot welding, and the non-overlapping portions of the two second mounting portions 21 can also be fixed to the inner rocker beam bottom wall 31 by spot welding.

[0054] It should be noted that for different wheelbase vehicles, the load transmitted by the two second side plates 22 to the lifting machine will be different when the vehicle is lifted. In order to ensure that the load on the two second side plates 22 is relatively uniform, the lengths of the two second side plates 22 can be designed to be different, thereby evenly distributing the load transmitted by the lifting machine, and providing a solution for vehicles with different wheelbases. The length direction of the second side plate 22 refers to the direction along the X-axis.

[0055] Optionally, referring to Figures 1-4 and Figures 7-8 , the bottom end of the second side plate 22 is higher than the first mounting portion 11, and the top end of the second side plate 22 is lower than the top end of the first side plate 12; and / or, the second side plate 22 is provided with a through hole 221; and / or, the first side plate 12 is provided with a vertical reinforcing rib 121.

[0056] In the embodiment, the bottom end of the second side plate 22 is higher than the first mounting portion 11, so as to ensure that the position of the second side plate 22 transmitting force to the first side plate 12 is different from the position of the first mounting portion 11 transmitting force to the first side plate 12, and prevent the first side plate 12 from concentrating the loads transmitted by the first mounting portion 11 and the second side plate 22 together, and thus cracking or breaking; the top end of the second side plate 22 is lower than the top end of the first side plate 12, which can reduce the material and weight, and can facilitate the second side plate 22 to twist and deform to some extent to eliminate part of the load during the transmission of the load. The second side plate 22 is provided with a through hole 221, which weakens the rigidity of the second side plate 22, and can facilitate the second side plate 22 to twist and deform to some extent to eliminate part of the load under the action of the lifting moment; secondly, the through hole 221 can also reduce the weight of the reinforcing support 1, which is beneficial to the lightweight design; and the through hole 221 can also serve as an operating hole for tools to pass through.

[0057] Unlike the second side plate 22 which can deform to some extent to eliminate part of the load, the top end of the first side plate 12 is connected with the top wall of the bottom cavity, and the bottom end is connected with the inner door sill beam bottom wall 31 through the first mounting portion 11. Here, the first side plate 12 is not allowed to deform as much as possible, and therefore the first side plate 12 is provided with a reinforcing rib 121 extending in the vertical direction to improve the rigidity of the first side plate 12 in the vertical direction; wherein the reinforcing rib 121 is a hollow structure, which can be formed by stamping the first side plate 12. The depth (i.e. the height of the protrusion) of the reinforcing rib 121 is, for example, 2mm, and the width is, for example, 25mm, which facilitates molding and also facilitates load transmission.

[0058] Another embodiment of the utility model provides a door sill beam which comprises the reinforcing support 1 as described above.

[0059] Since the technical improvement and technical effect of the door sill beam are the same as those of the reinforcing support 1, the door sill beam will not be described again.

[0060] Optionally, referring to Figures 5-10, the inner threshold beam 3 further comprises a shielding wall 34 extending downward from the transversely outer end (the right end shown in the figure) of the inner threshold beam bottom wall 31, wherein the vertical distance from the bottom end of the shielding wall 34 to the inner threshold beam top wall 32 represents the height of the entire inner threshold beam 3, which can be the same as the height of the conventional inner threshold beam 3, but the height of the inner threshold beam bottom wall 31 is higher than the height of the bottom wall of the conventional inner threshold beam 3, so as to save the space occupied by the conventional inner threshold beam 3, and the drain pipe or some lines of the automobile can be arranged in the space below the inner threshold beam bottom wall 31; or even the transversely end part of the battery pack can be extended to the space below the inner threshold beam bottom wall 31 to increase the capacity of the battery pack; and the drain pipe, the battery pack and the like are shielded by the shielding wall 34.

[0061] Optionally, referring to Figures 1-2 and Figures 5-10 , the threshold beam comprises the inner threshold beam 3 and an outer threshold beam (not shown in the figure) for enclosing a bottom cavity, the first mounting part 11 of the reinforcing bracket 1 is mounted at the transversely central position of the inner threshold beam bottom wall 31, and the second mounting part 21 of the reinforcing bracket 1 is located at the transversely central position of the inner threshold beam bottom wall 31 close to one side of the outer threshold beam; and the lifting seat 6 is mounted on the lower side of the inner threshold beam bottom wall 31, and the lifting surface 63 of the lifting seat 6 is located at the transversely central position of the inner threshold beam bottom wall 31 close to one side of the outer threshold beam.

[0062] In the embodiment, the bottom end of the lifting seat 6 has the lifting surface 63, and the lifting machine acts on the lifting surface 63 to lift the automobile. The lifting surface 63 is designed to be located at the transversely central position of the inner threshold beam bottom wall 31 close to one side of the outer threshold beam, for example, the lifting surface 63 is offset outward to be in contact with the shielding wall 34, so as to leave space below the inner threshold beam bottom wall 31 to arrange the drain pipe of the automobile or accommodate the transversely end part of the battery pack. The top end of the lifting seat 6 is provided with the first connecting hole 61, the part of the lifting seat 6 corresponding to the shielding wall 34 is provided with the second connecting hole 62, correspondingly, the first mounting part 11 and the inner threshold beam bottom wall 31 are respectively provided with the bracket connecting hole 111 corresponding to the first connecting hole 61, and the shielding wall 34 is provided with the wall hole corresponding to the second connecting hole 62, so as to pass the first bolt through the first connecting hole 61 and the bracket connecting hole 111 to bolt-fix the lifting seat 6, the inner threshold beam bottom wall 31 and the first mounting part 11, and pass the second bolt through the second connecting hole 62 and the wall hole of the shielding wall 34 to bolt-fix the lifting seat 6 and the shielding wall 34.

[0063] Specifically, the first mounting portion 11 can be located at the transverse center position of the inner rocker beam bottom wall 31, specifically, the bracket connecting hole 111 is located at the transverse center position of the inner rocker beam bottom wall 31, when the lifting machine acts on the lifting surface 63 to lift the automobile, the lifting force part can be transmitted from the first bolt to the first mounting portion 11, and then transmitted upward by the first mounting portion 11 through the first side plate 12, and the lifting force part can also be transmitted from the second bolt to the second mounting portion 21, the second side plate 22 and the first side plate 12 upward, so that multiple paths are simultaneously transmitted. Moreover, in the transverse direction of the bottom of the inner rocker beam 3, since the second mounting portion 21 of the reinforcing bracket 1 is relatively close to the lifting surface 63, the second mounting portion 21 is subjected to a lifting torque with a shorter force arm, so that the torsional deformation of the inner rocker beam 3 can be effectively prevented.

[0064] The utility model discloses still one embodiment provides a car body side wall, including the reinforcing bracket as described above, or, including the rocker beam as described above.

[0065] Since the technical improvement and technical effect of the car body side wall are the same as those of the reinforcing bracket or the rocker beam, the car body side wall will not be described again.
