[0011] Optionally, the side beam further includes a support component, which includes a second frame and a second transverse rib;

[0012] The second frame has a first side and a second side that are arranged opposite to each other in the left-right direction of the vehicle. The first side of the second frame is for facing the battery cell. The collapsible energy-absorbing component is connected to the second side of the second frame. The end of the collapsible energy-absorbing component away from the second frame is connected to the mounting connection component.

[0013] The second horizontal rib is set inside the second frame. There are multiple second horizontal ribs, which are inclined and connected end to end. Adjacent second horizontal ribs are set at an angle.

[0014] Optionally, the number of the second transverse ribs is three, with the connection point of two of the second transverse ribs being close to the connection point between the collapsible energy-absorbing component and the second surface of the second frame.

[0015] Optionally, the side beam further includes a guard plate mounting member connected to the second side of the second frame, wherein the connection point of another second transverse rib to the second frame is close to the guard plate mounting member.

[0016] Optionally, the second frame includes two oppositely arranged second horizontal plates and two oppositely arranged second vertical plates. The two ends of the two second horizontal plates are respectively connected to the two ends of the two second vertical plates. The two second horizontal plates and the two second vertical plates enclose an accommodating space. The second horizontal rib is arranged in the accommodating space. The two ends of the second horizontal rib in the left-right direction of the vehicle are respectively connected to the two second vertical plates.

[0017] Optionally, the side beam further includes a support component, the support component includes a second frame, the second frame includes a second vertical plate, the mounting connection component includes a connector, and the side wall of the connector is provided with a third vertical rib;

[0018] In the left-right direction of the vehicle, the thickness of the second vertical plate is greater than the thickness of the first vertical rib, and the thickness of the third vertical rib is greater than the thickness of the first vertical rib.

[0019] Optionally, there are two second vertical plates, one of which faces the battery cell, and the thickness of the second vertical plate closer to the battery cell is greater than the thickness of the second vertical plate farther away from the battery cell.

[0020] Optionally, the first frame includes a first horizontal plate, the side beam further includes a support component, the support component includes a second frame and a second horizontal rib, the second frame includes a second horizontal plate, and the mounting connection component includes a connector and a third horizontal plate, the connector being connected to the third horizontal plate;

[0027] The aforementioned technical solution, through the design of the first frame, maintains the overall structural connection and a certain degree of support before a collision, ensuring the connection between the mounting connection component and the crumple zone absorber. Upon impact, the first frame crumples, absorbing energy and protecting the battery cells. The first vertical rib, positioned close to the mounting connection component (which requires high structural strength to connect to the vehicle body), reinforces the structural strength of both the mounting connection component and the connection point with the first frame. Furthermore, the rib's proximity to the mounting connection component does not support the left and right ends of the first frame, thus preserving its crumple zone absorber function. This design also simplifies the structure of the crumple zone absorber, ensuring its effectiveness while reducing its weight.

[0028] Other features and advantages of this disclosure will be described in detail in the following detailed description section. Attached Figure Description

[0038] The specific embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this disclosure.

[0039] In this disclosure, unless otherwise stated, "inner" and "outer" refer to the inner and outer parts of the relevant components. Furthermore, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0040] In the description of this disclosure, it should also be noted that, unless otherwise expressly specified and limited, the terms "setup" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can be a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this disclosure according to the specific circumstances.

[0041] Side beams are important structures used to protect the battery's side impact safety and are also used to mount the battery on the vehicle body. Therefore, in order to protect the battery, side beams are often equipped with crumple zones to absorb energy.

[0042] The crumple zone design of the side beams in related technologies is quite complex and has high structural strength, which prevents effective crumple and energy absorption, affecting collision energy absorption and battery safety. Furthermore, current side beams are relatively heavy, failing to meet vehicle lightweighting requirements.

[0043] Therefore, such as Figures 1-4 As shown, one aspect of this disclosure provides a side beam for use in a battery pack, including a collapsible energy-absorbing component 1 and a mounting connection component 2.

[0044] The mounting connection component 2 is connected to the collapsible energy-absorbing component 1, and the mounting connection component 2 is used to connect to the vehicle body.

[0045] The collapsible energy-absorbing component 1 includes a first frame 11 and a first vertical rib 12. The first vertical rib 12 is inclined and is located inside the first frame 11. The lower end of the first vertical rib 12 is connected to one end of the first frame 11 near the mounting connection component 2, and the upper end of the first vertical rib 12 is connected to the middle of the first frame 11.

[0046] The first frame 11 of the collapsible energy-absorbing component 1 is configured to collapse upon impact, thereby absorbing impact energy. It is understood that the side beam can be a beam structure extending along the longitudinal direction of the vehicle.

[0047] In the above technical solution, the first frame 11 maintains the connection and a certain degree of support of the overall structure before a collision, ensuring the connection between the mounting connection component 2 and the crumple-absorbing component. Upon collision, the first frame 11 can crumple, absorbing energy and protecting the battery cells. The first vertical rib 12, positioned close to the mounting connection component 2, strengthens the structural strength of both the mounting connection component 2 and the connection point between it and the first frame 11. Since the mounting connection component 2 requires high structural strength to connect to the vehicle body, the first vertical rib 12 reinforces both the structural strength of the mounting connection component 2 and the connection point between it and the first frame 11. Furthermore, the first vertical rib 12, while close to the mounting connection component 2, does not support the two ends of the first frame 11 in the left-right direction of the vehicle, thus not affecting the crumple effect of the first frame 11 upon collision, ensuring its energy absorption function. In addition, by setting the side beam in this way, the structure of the collapsible energy-absorbing component 1 can be simplified, which can both ensure the collapsible energy-absorbing effect of the collapsible energy-absorbing component 1 and reduce the weight of the side beam.

[0048] In order to facilitate the connection between the first frame 11 and the mounting connection component 2 and maintain the connection strength, optionally, in one embodiment of the present disclosure, the first frame 11 includes a first horizontal plate 111. The number of first horizontal plates 111 is at least two and they are spaced apart along the height direction of the vehicle. At least one first vertical rib 12 is provided between each pair of oppositely arranged first horizontal plates 111. The lower end of the first vertical rib 12 is connected to the end of the corresponding first horizontal plate 111 near the mounting connection component 2, and the upper end of the first vertical rib 12 is connected to the middle of the corresponding other first horizontal plate 111.

[0049] The connection between one end of the first horizontal plate 111 and the mounting connection component 2, due to the extension of the first horizontal plate 111 along the left-right direction of the vehicle, does not affect the collapse of the first frame 11, thus providing a certain supporting effect. The first vertical rib 12, located between the two opposing first horizontal plates 111 and close to the mounting connection component 2, simplifies the structure, reduces weight, and simultaneously improves the structural strength of the mounting connection component 2 and the connection strength between the first horizontal plate 111 and the mounting connection component 2.

[0050] In some examples, there are two first horizontal plates 111, which are spaced apart and opposite each other in the height direction of the vehicle. There is one first vertical rib 12, located between the two first horizontal plates 111, and one end of each first horizontal plate 111 is connected to the mounting connection component 2. It should be noted that there can be multiple first vertical ribs 12, which can be arranged in parallel. In other examples, there can be more first horizontal plates 111, and the number of first vertical ribs 12 can be adjusted as needed.

[0051] In order to specifically strengthen the structural strength of the mounting connection component 2, optionally, in one embodiment of the present disclosure, the mounting connection component 2 includes a connector 21, wherein the width of the top of the connector 21 is greater than the width of the bottom of the connector 21 in the width direction of the side beam.

[0052] The connector 21 is used to connect to the vehicle body by bolts. The top of the connector 21 is used to contact the nut of the bolt. Therefore, the width of the top of the connector 21 is set to be large, and the structural strength requirement here is high.

[0053] The lower end of the first vertical rib 12 is close to the bottom of the connector 21, and the upper end of the first vertical rib 12 is close to the top of the connector 21. By setting it in this way, the first vertical rib 12 can adapt to the width dimensions of the top and bottom of the connector 21, thereby strengthening the structural strength of the connector 21 and improving the structural strength of the connection between the connector 21 and the vehicle body.

[0054] Optionally, in one embodiment of this disclosure, the mounting connection component 2 further includes a third horizontal plate 23 and a third vertical plate 24. There are two third horizontal plates 23, which are arranged opposite each other at a distance in the height direction of the vehicle. The third vertical plate 24 is connected to one end of the two third horizontal plates 23, and the ends of the two third horizontal plates 23 away from the third vertical plate 24 are connected to the two first horizontal plates 111. The connector 21 is connected to the two third horizontal plates 23, and the side wall of the connector 21 is provided with a third vertical rib 22.

[0055] The top of the connector 21 is connected to the upper third horizontal plate 23, and the bottom of the connector 21 is connected to the lower third horizontal plate 23. The third vertical rib 22 is located close to the axis of the connector 21. The first vertical rib 12 and the third vertical plate 24 are located on the left and right sides of the connector 21, respectively. Thus, the first vertical rib 12, the third vertical plate 24 and the third vertical rib 22 can provide three-point support for the top and bottom of the connector 21, thereby strengthening the structural strength of the connector 21.

[0056] Optionally, in one embodiment of this disclosure, the side beam further includes a support component 3, which includes a second frame 31 and a second transverse rib 32.

[0057] The second frame 31 has a first surface and a second surface that are arranged opposite to each other in the left-right direction of the vehicle. The first surface of the second frame 31 is used to face the battery cell. The collapsible energy absorption component 1 is connected to the second surface of the second frame 31. The end of the collapsible energy absorption component 1 away from the second frame 31 is connected to the mounting connection component 2.

[0058] The second frame 31 serves to provide blocking and support, protecting the individual battery cells. The collapsible energy-absorbing component 1 is located between the mounting connection component 2 and the second frame 31. It is understood that the second frame 31 has high structural strength. After the collapsible energy-absorbing component 1 absorbs some of the collision energy, the second frame 31 needs to isolate the energy from being transferred to the individual battery cells, preventing thermal runaway and other problems caused by the collision energy.

[0059] The second horizontal rib 32 is disposed within the second frame 31. There are multiple second horizontal ribs 32, which are inclined and connected end to end, with adjacent second horizontal ribs 32 arranged at an angle. The second horizontal ribs 32 can strengthen the structural strength of the second frame 31, ensuring that the second frame 31 maintains sufficient structural strength to protect the battery cells.

[0060] In this design, multiple second horizontal ribs 32 are inclined and connected end-to-end. The two ends of each second horizontal rib 32 are connected to the inner wall of the second frame 31, creating an angle between adjacent second horizontal ribs 32. This angled arrangement, combined with the inner wall of the second frame 31, forms a triangular structure. This triangular structure provides high stability and supports the second frame 31 against forces in the lateral direction of the vehicle, thus strengthening the structure. This design reduces the number of second horizontal ribs 32, lowering the overall weight and manufacturing cost of the side beam, while simultaneously increasing the structural strength of the second frame 31 and ensuring its protective function for the battery cells in the lateral direction of the vehicle.

[0061] Optionally, in one embodiment of this disclosure, the number of second horizontal ribs 32 is three, with the connection point of two second horizontal ribs 32 located near the connection point between the collapsible energy-absorbing component 1 and the second surface of the second frame 31. This arrangement strengthens the connection between the collapsible energy-absorbing component 1 and the second surface of the second frame 31, ensuring the connection strength between them. Furthermore, since the collision energy is transferred from the collapsible energy-absorbing component 1 to the second frame 31, strengthening the connection between the second frame 31 and the collapsible energy-absorbing component 1 enhances the structural strength of the connection, thereby facilitating the protection of the battery cells by the second frame 31.

[0062] In some examples, one of the two first horizontal plates 111 is connected to the top of the second frame 31, and the other first horizontal plate 111 is connected to the second side of the second frame 31 near its top. The connection point of the two second horizontal ribs 32 coincides with the connection point of the first horizontal plate 111 to the second side of the second frame 31 near its top. This can block the collision energy transmitted from the second horizontal plate 311 and achieve the protection of the battery cell.

[0063] Optionally, in one embodiment of this disclosure, the side beam further includes a guard plate mounting member 33, which is connected to the second surface of the second frame 31. The connection point of another second transverse reinforcement 32 with the second frame 31 is close to the guard plate mounting member 33. The guard plate can be installed using the guard plate mounting member 33, and the proximity of the second transverse reinforcement 32 to the second frame 31 strengthens the structural strength of the second frame 31 at the guard plate mounting member 33.

[0064] Optionally, in one embodiment of this disclosure, the second frame 31 includes two opposing second horizontal plates 311 and two opposing second vertical plates 312. The two ends of the two second horizontal plates 311 are respectively connected to the two ends of the two second vertical plates 312. The two second horizontal plates 311 and the two second vertical plates 312 enclose an accommodating space. A second horizontal rib 32 is disposed in the accommodating space. The two ends of the second horizontal rib 32 in the left-right direction of the vehicle are respectively connected to the two second vertical plates 312.

[0065] The two second horizontal plates 311 and the two second vertical plates 312 form a rectangular structure, providing both partitioning and support. The second horizontal ribs 32 enhance the structural strength of the second frame 31 in the left-right direction of the vehicle. One of the second vertical plates 312 is connected to the collapsible energy-absorbing component 1, while the other second vertical plate 312 faces the battery cell.

[0066] Optionally, in one embodiment of this disclosure, the side beam further includes a support component 3, the support component 3 includes a second frame 31, the second frame 31 includes a second vertical plate 312, the mounting connection component 2 includes a connector 21, and the side wall of the connector 21 is provided with a third vertical rib 22.

[0067] In the left-right direction of the vehicle, the thickness of the second vertical plate 312 is greater than the thickness of the first vertical rib 12, and the thickness of the third vertical rib 22 is greater than the thickness of the first vertical rib 12.

[0068] The second frame 31 has high structural strength requirements and needs to isolate collision energy to protect the battery cells. Therefore, the thickness of the second vertical plate 312 is set to be relatively large. The first vertical rib 12 is mainly used to strengthen the structural strength of the connector 21. Meanwhile, the first frame 11 needs to collapse and absorb energy, and its structural strength requirements are not high. Therefore, the thickness of the first vertical rib 12 is set to be relatively small. This allows the thickness to be set reasonably according to the different functions of different areas of the side beam, which can reduce the weight and cost of the side beam while ensuring that the relevant functions of the side beam are not weakened.

[0069] Optionally, in one embodiment of this disclosure, there are two second vertical plates 312, one of which faces the battery cell, and the thickness of the second vertical plate 312 closer to the battery cell is greater than the thickness of the second vertical plate 312 farther from the battery cell. This arrangement provides better protection for the battery cell.

[0070] Alternatively, in another embodiment of this disclosure, there are two second vertical plates 312, one of which faces the battery cell, and the two second vertical plates 312 may have the same thickness.

[0071] The thicknesses of the second vertical plate 312, the third vertical rib 22, and the first vertical rib 12 are not limited here and can be set according to actual needs. Optionally, in one embodiment of this disclosure, in the left-right direction of the vehicle, the thickness of the second vertical plate 312 is set to 2mm-2.5mm, the thickness of the third vertical rib 22 is set to 2.3mm-2.7mm, and the thickness of the first vertical rib 12 is set to 1.8mm-2.2mm. This setting ensures the supporting strength of the second vertical plate 312, the third vertical rib 22, and the first vertical rib 12 while reducing weight.

[0072] The thickness of the second vertical plate 312 closest to the battery cell is set to 2.1mm-2.5mm, and the thickness of the second vertical plate 312 furthest from the battery cell is set to 2mm-2.4mm. The thickness of the third vertical plate 24 is set to 1.6mm-2.2mm. In some examples, the thickness of both second vertical plates 312 can be set to 2.2mm, or one can be set to 2.2mm and the other to 2.3mm. The thickness of the third vertical rib 22 can be set to 2.5mm, and the thickness of the first vertical rib 12 can be set to 2mm.

[0073] Optionally, in one embodiment of this disclosure, the first frame 11 includes a first horizontal plate 111, and the side beam further includes a support component 3. The support component 3 includes a second frame 31 and a second horizontal rib 32. The second frame 31 includes a second horizontal plate 311. The mounting connection component 2 includes a connector 21 and a third horizontal plate 23. The connector 21 is connected to the third horizontal plate 23.

[0074] In the height direction of the vehicle, the thickness of the third horizontal plate 23 is greater than the thickness of the second horizontal rib 32, and the thickness of the second horizontal rib 32 and the second horizontal plate 311 is greater than the thickness of the first horizontal plate 111.

[0075] The third horizontal plate 23 is used to install the connector 21 to ensure the connection between the connector 21 and the vehicle body. Therefore, the third horizontal plate 23 has high structural strength requirements and needs to provide sufficient support for the connector 21 to prevent the connector 21 from falling off the vehicle body. Thus, the thickness of the third horizontal plate 23 is set to be relatively large. The first horizontal plate 111 is mainly used for connection. At the same time, the first frame 11 needs to collapse and absorb energy, so the structural strength requirements are not high. Therefore, the thickness of the first horizontal plate 111 is set to be relatively small. This allows the thickness to be set reasonably according to the different functions of different areas of the side beam, which can reduce the weight and cost of the side beam while ensuring that the relevant functions of the side beam are not weakened.

[0076] Optionally, in one embodiment of this disclosure, in the left-right direction of the vehicle, the width of the top of the connector 21 is greater than the width of the bottom of the connector 21, and there are two third horizontal plates 23, which are respectively connected to the top and bottom of the connector 21.

[0077] In the vehicle's height direction, the thickness of the third horizontal plate 23 near the top of the connector 21 is greater than the thickness of the third horizontal plate 23 near the bottom of the connector 21. Since the width of the top of the connector 21 is greater than the width of the bottom, the structural support requirements for the top of the connector 21 are higher, hence the larger thickness of the third horizontal plate 23 near the top. Conversely, the structural support requirements for the bottom of the connector 21 are lower, hence the smaller thickness of the third horizontal plate 23 near the bottom. This allows for targeted structural reinforcement at the desired locations, reducing the weight and cost of the side beams.

[0078] Optionally, in one embodiment of this disclosure, the third horizontal plate 23 near the top of the connector 21 has a first plate body near the first vertical rib 12 and a second plate body away from the first vertical rib 12, wherein the thickness of the first plate body is greater than the thickness of the second plate body. Since the top of the first vertical rib 12 is far from the connector 21, the thickness of the first plate body is set to be larger, which can ensure the supporting effect on the connector 21.

[0079] The thickness dimensions of the third horizontal plate 23, the second horizontal rib 32, the second horizontal plate 311, and the first horizontal plate 111 are not limited here and can be set according to actual needs. Optionally, in one embodiment of this disclosure, in the height direction of the vehicle, the thickness dimension of the third horizontal plate 23 is set to 1.8mm-3.7mm, the thickness dimension of the second horizontal rib 32 is set to 1.4mm-1.8mm, the thickness dimension of the second horizontal plate 311 is set to 2.3mm-2.7mm, and the thickness dimension of the first horizontal plate 111 is set to 1.6mm-2mm. With this setting, the supporting strength of the third horizontal plate 23, the second horizontal rib 32, the second horizontal plate 311, and the first horizontal plate 111 can be guaranteed while reducing weight.

[0080] The thickness of the third horizontal plate 23 near the top of the connector 21 is set to 2.3mm-3.7mm, the thickness of the first plate is set to 3.3mm-3.7mm, and the thickness of the second plate is set to 2.3mm-2.7mm. The thickness of the third horizontal plate 23 near the bottom of the connector 21 is set to 1.8mm-2.2mm.

[0081] In some examples, the thickness of the third horizontal plate 23 is set to 2.5 mm and 2 mm, the thickness of the second horizontal rib 32 is set to , the thickness of the second horizontal plate 311 is set to , and the thickness of the first horizontal plate 111 is set to 1.8 mm.
