[0041] Embodiment 1

[0042] As Figure 1 shown, a power battery frame beam is provided in the first aspect of this application, including a first plate body 1 and a second plate body 2; the first plate body 1 extends along a first direction A, and at least one first chamber 11 extending along the first direction A is provided in the first plate body 1, and an energy absorption structure 111 is provided in the first chamber 11; the second plate body 2 extends along the first direction A, the second plate body 2 is located on one side of the first plate body 1 in a second direction B perpendicular to the first direction A and has a preset angle R relative to the first plate body 1, and the second plate body 2 and the first plate body 1 enclose a receiving space 4 for receiving a power battery.

[0043] Specifically, the power battery frame beam of the present application includes a first plate body 1 and a second plate body 2. During the installation and use on a new energy vehicle, the first plate body 1 supports the bottom of the power battery, and the second plate body 2 is located on the front side of the power battery in the vehicle body length direction. Thus, when the new energy vehicle is running, the second plate body 2 is first impacted by an obstacle and absorbs part of the impact energy. And as the vehicle continues to run, the obstacle passes through the second plate body 2 and rubs against the first plate body 1 and simultaneously squeezes the energy absorption structure 111 arranged in the first chamber 11 of the first plate body 1, which can improve the stiffness and compressive strength of the first plate body 1 and absorb the extrusion force to prevent the first plate body 1 from cracking. Furthermore, it can fully protect the power battery in the accommodation space 4 surrounded by the second plate body 2 and the first plate body 1. And the protection of the first plate body 1 and the second plate body 2 for the power battery covers the whole process of the bottom of the new energy vehicle encountering an obstacle and passing through during driving, improving the safety of the new energy vehicle.

[0044] The energy absorption structure 111 arranged in the first chamber 11 can be a honeycomb structure, a corrugated thin-wall structure, a laminated structure, etc., without specific limitation, as long as it can improve the stiffness and compressive strength of the first plate body 1 and absorb the extrusion force to prevent the first plate body 1 from cracking. To meet the lightweight requirement, the first plate body 1 and the second plate body 2 can be made of aluminum or aluminum alloy, and the energy absorption structure 111 can also be made of aluminum or aluminum alloy.

[0045] In the present application, the first plate body 1 and the second plate body 2 can be integrally formed by means such as injection extrusion, or can be welded into one body, without specific limitation. In the extrusion process, the first chamber 11 of the first plate body 1 is formed simultaneously and can extend along the first direction A. The energy absorption structure 111 is arranged in the first chamber 11 and can be connected by means such as welding, gluing, screw fastening, etc., without specific limitation.

[0046] In the present application, the second plate 2 is located on one side of the first plate 1 in a second direction B perpendicular to the first direction A and has a preset angle R relative to the first plate 1. The second plate 2 and the first plate 1 enclose a receiving space 4, which is used to receive a power battery. The preset angle R can be 90°, in which case the second plate body 2 is perpendicular to the first plate body 1; it can also be 80°, 70° and other angles, which are not listed here one by one. In this case, the second plate body 2 has an acute angle with respect to the first plate body 1, and when the first plate body 1 is horizontally installed as a bottom component of the vehicle, the second plate body 2 is inclined toward the first plate body 1; it can also be 100°, 110°, 120° and other angles, which are not listed here one by one. In this case, the second plate body 2 has an obtuse angle with respect to the first plate body 1, and when the first plate body 1 is horizontally installed as a bottom component of the vehicle, the second plate body 2 is inclined away from the first plate body 1. The preset angle R of the present application is not specifically limited, as long as the second plate body 2 located on the front side of the power battery in the length direction of the vehicle body can absorb part of the impact energy during the driving process of the new energy vehicle to ensure the overall structural strength of the power battery frame beam without cracking.

[0047] In a first aspect, the present application provides a power battery frame beam, comprising a first plate body 1 and a second plate body 2, wherein the first plate body 1 extends along a first direction A, and is provided with at least one first chamber 11 extending along the first direction A, wherein the first chamber 11 is provided with an energy absorbing structure 111; the second plate body 2 extends along the first direction A, and is located on one side of the first plate body 1 in a second direction B perpendicular to the first direction A and has a preset angle R relative to the first plate body 1, and the second plate body 2 and the first plate body 1 enclose a housing space 4, and the housing space 4 is used to accommodate a power battery. The power battery frame beam provided in the present application, if the bottom of the new energy vehicle encounters an obstacle during the driving process, the obstacle first hits the second plate body 2 located on one side of the first plate body 1 in the second direction B perpendicular to the first direction A and with a preset angle R relative to the first plate body 1, and can effectively absorb part of the impact energy before the first plate body 1. During the driving process of the vehicle, the obstacle passes through the second plate body 2 and scrapes and squeezes the first plate body 1 at the same time. The energy absorption structure 111 provided in the first chamber 11 of the first plate body 1 can improve the rigidity and compressive strength of the first plate body 1, and absorb the squeezing force to avoid the first plate body 1 from breaking, thereby forming sufficient protection for the power battery in the accommodating space 4 enclosed by the second plate body 2 and the first plate body 1, and the protection of the power battery by the first plate body 1 and the second plate body 2 covers the entire process of the bottom encountering and passing obstacles during the driving process of the new energy vehicle, thereby improving the safety of the new energy vehicle. Through the application of this application, the problem in the prior art that the frame beam of the power battery has a weak ability to resist the impact, scratches and extrusion of obstacles on the road surface, and cannot effectively absorb energy and is prone to rupture, causing the power battery to have the risk of fire and explosion, posing a huge safety hazard, is solved.

[0048] In some embodiments, the preset angle R is 90°.

[0049] Specifically, during the driving of new energy vehicles, various complex road conditions such as potholes, bumps, and stone roads may be encountered, which may cause the bottom of the vehicle to be hit, scratched, and squeezed by obstacles. During the use of the power battery frame beam of the present application, the first plate 1 supports the bottom of the power battery, and the second plate 2 is located at the front side of the power battery in the length direction of the vehicle body. When the new energy vehicle is driving, the second plate 2 is first hit by an obstacle, and as the vehicle continues to drive, the obstacle passes through the second plate 2 and is scratched and squeezed by the first plate 1 at the same time. In order for the second plate 2 to absorb more energy before the obstacle passes through the first plate 1, In order to avoid the rupture of the power battery frame beam to protect the power battery in the accommodating space 4, the present application sets the preset angle R of the second plate body 2 relative to the first plate body 1 to be 90°, so that the second plate body 2 can withstand and absorb more loads in the horizontal direction, reducing the energy absorption burden of the first plate body 1, and at the same time, due to the energy absorption structure 111 set in the first chamber 11 of the first plate body 1, the stiffness and compressive strength of the first plate body 1 are improved, and the extrusion force is absorbed to avoid the first plate body 1 from rupture, thereby ensuring the overall structural strength of the power battery frame beam, forming sufficient protection for the power battery, and improving the safety of new energy vehicles.

[0050] like Figure 2 and Figure 3 As shown, in some embodiments, the second plate body 2 is provided with at least one second chamber 21 extending along the first direction A, and the second chamber 21 is arranged at a position away from the side surface of the second plate body 2 close to the first plate body 1 along the second direction B away from the first plate body 1.

[0051] Specifically, in order to meet the layout requirements of high and low voltage connectors, water inlets and outlets of the cooling system, explosion-proof valves, etc. required for the operation of new energy vehicle power batteries, the present application is provided with at least one second chamber 21 extending along the first direction A on the second plate body 2 to provide the required space for the layout. At the same time, the extension of the second chamber 21 along the first direction A also meets the process requirements of producing and manufacturing the power battery frame beam of the present application by extruding it through an extrusion die and then cutting it.

[0052] The installation position of the second chamber 21 of this application is far from the side surface of the second plate body 2 near one end of the first plate body 1 that deviates from the first plate body 1 along the second direction B. This is considered because during the driving process of new energy vehicles, various complex road conditions such as potholes, bumps, and rocky roads will be encountered, which will cause the bottom of the vehicle to be impacted, scratched, and squeezed by obstacles. In this application, the second plate body 2 in the power battery frame beam is first impacted by the obstacle. As the vehicle continues to drive, the obstacle passes through the second plate body 2 and scratches and squeezes the first plate body 1 at the same time. In order to enable the second plate body 2 to effectively absorb the impact energy during the impact process, this application makes the installation position of the second chamber 21 far from the side surface of the second plate body 2 near one end of the first plate body 1 that deviates from the first plate body 1 along the second direction B, so that the second chamber 21 is not opened at the place where the second plate body 2 contacts the obstacle and is in a solid state, thereby ensuring the structural strength and impact resistance at this place and reducing the risk of rupture of the second plate body 2, the first plate body 1, and the overall power battery frame beam.

[0053] As Figure 2 and Figure 3 shown, in some embodiments, a first opening 22 is provided on the side surface of the second plate body 2 that deviates from the first plate body 1 in the second direction B; a second opening 23 is provided on the side surface of the second plate body 2 that is close to the first plate body 1 corresponding to the first opening 22, and both the first opening 22 and the second opening 23 are at least partially communicated with the second chamber 21.

[0054] Specifically, in order to meet the layout requirements of high and low voltage connectors, inlet and outlet water ports of the cooling system, explosion-proof valves, etc. required for the operation of the power battery of new energy vehicles, this application provides a first opening 22 on the side surface of the second plate body 2 that deviates from the first plate body 1 in the second direction B, and a second opening 23 is provided on the side surface close to the first plate body 1 corresponding to the first opening 22. Both the first opening 22 and the second opening 23 are at least partially communicated with the second chamber 21, so that components such as pipelines and valve bodies outside the second plate body 2 can be connected to the power battery in the accommodation space 4 through the first opening 22 and the second opening 23 on both sides of the second plate body 2, and the second chamber 21 also provides the required layout space.

[0055] As Figure 2 and Figure 3 shown, in some embodiments, a third opening 24 is provided on the side surface of the second plate body 2 that deviates from the first plate body 1 in the third direction C perpendicular to the first plate body 1, and the third opening 24 is at least partially communicated with the second chamber 21.

[0056] Specifically, when the battery cell frame beam of the present application is in use, it is placed at the bottom of the vehicle to match the position of the power battery. In order to achieve a firm connection with the vehicle floor frame or cross beam, the present application opens a third opening 24 on the surface of the second body facing away from the first plate body 1 in the third direction C perpendicular to the first plate body 1. The third opening 24 can be a threaded hole, a bolt hole, etc., and the specific shape and size can be adjusted adaptively according to the installation requirements.

[0057] As Figure 4 shown, in some embodiments, it further includes: a third plate body 3, the third plate body 3 extends along the first direction A and is connected to the side of the first plate body 1 facing away from the second plate body 2 along the second direction B, and the third plate body 3 is provided with at least one third chamber 31 extending along the first direction A; the third plate body 3, the first plate body 1 and the second plate body 2 enclose an accommodation space 4.

[0058] Specifically, the present application further connects a third plate body 3 to the side of the first plate body 1 facing away from the second plate body 2. During the driving of the vehicle, the obstacle first impacts the second plate body 2 and part of the energy is absorbed, and then it is scratched and squeezed through the bottom surface of the first plate body 1. The energy absorption structure 111 provided in the first chamber 11 of the first plate body 1 improves the stiffness and compressive strength of the first plate body 1 and absorbs the extrusion force to prevent the first plate body 1 from cracking. The setting of the third plate body 3 can be understood as the extension of the first plate body 1 along the second direction B away from the second plate body 2. The third plate body 3 is provided with at least one third chamber 31 extending along the first direction A to reduce the weight of the third plate body 3 and meet the requirements of lightweight design. At the same time, the third chamber 31 can also serve as an energy absorption chamber to produce an energy absorption effect. The third plate body 3 and the first plate body 1 can be integrally formed by means of extrusion and injection molding, and the first chamber 11 corresponding to the energy absorption structure 111 and the third chamber 31 are respectively opened at one end facing away from the second plate body 2, thereby ensuring the overall structural strength of the first plate body 1 and the third plate body 3 in the second direction B and avoiding the risk of cracking.

[0059] As Figure 1 and Figure 5 shown, in some embodiments, the cross-section of the energy absorption structure 111 along the first direction A is honeycomb-shaped.

[0060] Specifically, in order to improve the energy absorption effect of the energy absorption structure 111, so as to enhance the stiffness and compressive strength of the first plate body 1 when an obstacle rubs against the second plate body 2 and applies a squeezing force to the first plate body 1 during the driving of the vehicle, and absorb the squeezing force to prevent the first plate body 1 from cracking, the energy absorption structure 111 is provided in this application to have a honeycomb shape in the cross-section along the first direction A. The honeycomb-shaped energy absorption structure 111 can provide high bending stiffness and shear resistance. When subjected to impact or squeezing force, it can absorb a large amount of energy through the gradual collapse of the cells, and at the same time has the characteristics of light weight. The energy absorption structure 111 of this application can adopt various forms such as hexagonal honeycomb structure, hybrid shape honeycomb structure, honeycomb-like multi-stage thin-wall structure, etc., which is not specifically limited. As long as it can provide a good energy absorption effect and prevent the first plate body 1 from cracking, and then form sufficient protection for the power battery in the accommodation space 4 enclosed by the second plate body 2 and the first plate body 1.

[0061] In some embodiments, the energy absorption structure 111 is adhesively bonded in the first chamber 11.

[0062] Specifically, in order to achieve the overall light weight and good energy absorption effect of the power battery frame beam, this application realizes the setting of the energy absorption structure 111 by adhesively bonding the energy absorption structure 111 in the first chamber 11. When adhesively bonding, adhesives such as double-sided tape, quick-drying glue, and epoxy structural glue are respectively coated on the two side surfaces of the energy absorption structure 111 in the third direction C, and then the energy absorption structure 111 is placed into the first chamber 11 extending along the first direction A, so that the two side surfaces of the energy absorption structure 111 coated with the adhesive are in contact with the inner wall of the first chamber 11 to achieve adhesive fixation.

[0066] The second aspect of the present application provides a power battery assembly, including a power battery frame beam. The power battery frame beam includes a first plate body 1 and a second plate body 2. The first plate body 1 extends along a first direction A. At least one first chamber 11 extending along the first direction A is provided in the first plate body 1, and an energy absorption structure 111 is provided in the first chamber 11. The second plate body 2 extends along the first direction A. The second plate body 2 is located on one side of the first plate body 1 in a second direction B perpendicular to the first direction A and has a preset angle R relative to the first plate body 1. The second plate body 2 and the first plate body 1 enclose a accommodation space 4 for accommodating the power battery. For the power battery frame beam provided by the present application, during the driving of a new energy vehicle, if an obstacle is encountered at the bottom, the obstacle first impacts the second plate body 2 located on one side of the first plate body 1 in the second direction B perpendicular to the first direction A and having a preset angle R relative to the first plate body 1, and can effectively absorb part of the impact energy prior to the first plate body 1.

The energy absorption structure 111 provided in the first chamber 11 of the first plate body 1 can improve the stiffness and compressive strength of the first plate body 1 and absorb the squeezing force to prevent the first plate body 1 from cracking, thereby fully protecting the power battery in the accommodation space 4 enclosed by the second plate body 2 and the first plate body 1. Moreover, the protection of the first plate body 1 and the second plate body 2 for the power battery covers the whole process of encountering and passing through an obstacle at the bottom during the driving of the new energy vehicle, improving the safety of the new energy vehicle.

The energy absorption structure 111 provided in the first chamber 11 of the first plate body 1 can improve the stiffness and compressive strength of the first plate body 1 and absorb the squeezing force to prevent the first plate body 1 from cracking, thereby providing full protection for the power battery in the containing space 4 enclosed by the second plate body 2 and the first plate body 1. Moreover, the protection of the first plate body 1 and the second plate body 2 for the power battery covers the whole process of encountering and passing through obstacles at the bottom during the driving of the new energy vehicle, improving the safety of the new energy vehicle. Through the application of the present application, the problem in the prior art that the power battery frame beam has weak ability to resist the impact, rubbing and squeezing of obstacles on the road surface, and cannot effectively absorb energy and is prone to cracking, resulting in the risk of fire and explosion of the power battery and bringing huge safety hazards, is solved.

Any person skilled in the art within the technical scope disclosed by the present utility model can easily think of changes or substitutions, which should all be covered within the protection scope of the present utility model. Therefore, the protection scope of the present utility model should be subject to the protection scope of the claimed rights.
