[0079] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative effort belong to the protection scope of the present application.

[0080] Reference Figure 1 and Figure 2For the convenience of introduction, the up, down, left, right, front, and back directions are used in the corresponding drawings to facilitate the introduction of the relative positional relationship between the parts in this application, which should not be understood as the limitation of the absolute position.

[0081] Also, in this application, the first direction corresponds to the front-back direction, the second direction corresponds to the up-down direction, and the third direction corresponds to the left-right direction; as mentioned above, the first direction indicates the front-back direction here is only for the convenience of introducing the specific embodiments of this application, and the first direction does not have an absolute corresponding relationship with the front-back direction, similarly, the second direction does not have an absolute corresponding relationship with the up-down direction, and the third direction does not have an absolute corresponding relationship with the left-right direction.

[0082] The first direction, the second direction, and the third direction of this application are also only for expressing the relative positional relationship, they only indicate the approximate direction, not the absolute geometric relationship.

[0083] According to the first aspect of the present application, with reference to Figures 1 to 10 The present application provides a frame beam 100 for constituting a frame 10 of a vehicle 1, the frame beam 100 is provided with: a liquid discharge flow channel 100a capable of discharging at least liquid flowing along the frame beam 100 from the frame beam 100.

[0084] Through the above technical solution, by opening the liquid discharge flow channel on the frame beam, the liquid in the frame beam can be discharged by using the liquid discharge flow channel, and the protection of the cabin space can be completed without using a sealing element.

[0085] When the frame 10 is designed in an integrated manner with the power assembly (such as a battery pack), damage to the power assembly can also be avoided, and the protection of the cabin space and the battery pack can be completed without using a sealing element.

[0086] The frame beam 100 of the present application does not need to additionally provide a sealing element to achieve the protection of the cabin space and the power assembly, realizes the integrated setting of the frame beam 100, and does not need to use other ways, such as adding a sealing element, to achieve the discharge of the liquid outside the vehicle 1 while also achieving the integration of the frame beam 100.

[0087] In some embodiments, the liquid discharge flow channel 100a passes through the beam wall of the frame beam 100 to discharge at least the liquid flowing along the frame beam 100 from the frame beam 100 to the outside of the vehicle.

[0088] By passing the liquid discharge flow channel 100a through the beam wall of the frame beam 100, the effect of discharging at least the liquid flowing along the frame beam 100 from the frame beam 100 to the outside of the vehicle is achieved.

[0089] In some embodiments, the liquid is able to flow to the liquid discharge channel 100a in a first direction; wherein the first direction is parallel or inclined to the length direction of the frame beam 100.

[0090] By flowing the liquid to the liquid discharge channel 100a in the first direction, wherein the first direction is parallel to the length direction of the frame beam 100, the liquid is able to flow directly to the liquid discharge channel 100a to discharge the frame beam 100, which is able to discharge the liquid in the minimum path.

[0091] Alternatively, the liquid can flow to the liquid discharge channel 100a in a second direction, wherein the second direction is inclined to the length direction of the frame beam 100, the liquid is able to flow to the liquid discharge channel 100a along a relatively longer path to discharge the frame beam 100, which is able to discharge the liquid in a path slightly larger than the minimum path.

[0092] It should be noted that the liquid enters the frame beam 100 from the position of the frame enveloping the tire during the driving of the vehicle 1, for example, when the vehicle 1 wades.

[0093] In some embodiments, referring to Figure 3 and 5 , the liquid discharge channel 100a is opened on the frame beam 100 close to the power assembly of the vehicle 1.

[0094] By opening the liquid discharge channel 100a on the frame beam 100 close to the power assembly of the vehicle 1, the liquid is able to be discharged from the relatively low position of the frame beam 100.

[0095] Exemplarily, when the frame beam 100 is installed as a beam structure with other beam structures of the frame, the frame beam 100 can be inclined to the horizontal plane, and the liquid is then discharged from the lowest position of the frame beam 100.

[0096] The position is arranged to ensure that the liquid is discharged from the frame beam 100 as much as possible and as quickly as possible.

[0097] It can be understood that the position of the frame beam 100 where the liquid discharge channel 100a is located can be defined as a wet area.

[0098] In some embodiments, referring to Figure 6 and Figure 7 , the liquid discharge channel 100a penetrates the beam wall of the frame beam 100 in a second direction; wherein the second direction is inclined or perpendicular to the first direction.

[0099] By penetrating the drain flow channel 100a through the beam wall of the frame beam 100 in the second direction which is inclined or perpendicular to the first direction, the frame beam 100 can realize the effect of draining liquid out of the frame beam 100 by only opening one drain flow channel 100a, which is simple in structure, easy to form, and high in structural stability.

[0100] In some embodiments, referring to Figure 6 and Figure 7 , the drain flow channel 100a is configured as a through-hole structure.

[0101] By configuring the drain flow channel 100a as a through-hole structure, the overall structure of the frame beam 100 is more stable, and the frame beam 100 can be directly stamped into a through-hole without the need for other structures.

[0102] In some embodiments, referring to Figure 7 , the frame beam 100 further has a liquid guide flow channel 100b.

[0103] The liquid guide flow channel 100b is used to guide liquid along the length direction of the frame beam 100 to the drain flow channel 100a, wherein the liquid guide flow channel 100b is configured to communicate with the drain flow channel 100a.

[0104] By providing the liquid guide flow channel 100b on the frame beam 100, the liquid guide flow channel 100b can guide liquid along the length direction of the frame beam 100 to the drain flow channel 100a, thereby achieving the effect of guiding liquid.

[0105] Exemplarily, the liquid guide flow channel 100b can be a liquid guide flow channel 100b formed in space along the length direction of the frame beam 100, and the cross section of the frame beam 100 can be arranged in a U shape, and the liquid flows along the inner wall surface of the frame beam 100 to the drain flow channel 100a.

[0106] In some embodiments, the frame beam 100 includes a longitudinal beam.

[0107] The frame beam 100 of the present application includes a longitudinal beam, so that the direction of liquid flowing in the first direction is the length direction of the vehicle 1, and the liquid can flow into the liquid guide flow channel 100b from the inner wall surface of one end of the longitudinal beam away from the drain flow channel 100a and flow along the inner wall surface of the longitudinal beam to the drain flow channel 100a.

[0108] It can be understood that the liquid entering the liquid guide flow channel 100b is through the hole on the longitudinal beam due to the process, and the hole due to the process cannot be avoided due to the safety performance of the frame, so some liquid will pass through the process hole of the longitudinal beam into the flow channel.

[0109] Therefore, the longitudinal beam with this structure can directly drain liquid outside without the need for additional sealing members.

[0110] According to a second aspect of the present application, there is provided a vehicle frame 10 comprising a vehicle frame beam 100 as above.

[0111] The vehicle frame comprises the vehicle frame beam 100 as above, and thus has all the beneficial effects of the vehicle frame beam 100 as above, which will not be repeated here.

[0112] In some embodiments, the vehicle frame further comprises an upper cross beam assembly 200.

[0113] The upper cross beam assembly 200 is configured to block the liquid in the liquid guide channel 100b in the vehicle frame beam 100, wherein a projection of an inner wall surface of the liquid guide channel 100b along a length direction of the vehicle frame beam 100 is located within a projection of the upper cross beam assembly 200.

[0114] By arranging the upper cross beam assembly 200 to block the liquid in the liquid guide channel 100b in the vehicle frame beam 100 from flowing to the power assembly or the in-cabin space of the vehicle 1, and by arranging the projection of the inner wall surface of the liquid guide channel 100b along the length direction of the vehicle frame beam 100 to be located within the projection of the upper cross beam assembly 200, the protection degree of the power assembly or the in-cabin space of the vehicle 1 can be further improved by the upper cross beam assembly 200.

[0115] In some embodiments, the upper cross beam assembly 200 comprises an upper cross beam 210 and a first connecting plate 220.

[0116] The first connecting plate 220 is connected between the upper cross beam 210 and the vehicle frame beam 100, and a projection of an inner wall surface of the liquid guide channel 100b along a first direction is located within a projection of the first connecting plate 220, so that the first connecting plate 220 can block the liquid in the liquid guide channel 100b in the vehicle frame beam 100.

[0117] By arranging the first connecting plate 220 between the upper cross beam 210 and the vehicle frame beam 100, and by arranging the first connecting plate 220 to connect the upper cross beam 210 to the vehicle frame beam 100, and by arranging a projection of an inner wall surface of the liquid guide channel 100b along a first direction to be located within a projection of the first connecting plate 220, so that the first connecting plate 220 can block the liquid in the liquid guide channel 100b in the vehicle frame beam 100, the effect of blocking the liquid in the liquid guide channel 100b in the vehicle frame beam 100 is further improved.

[0118] And by arranging the first connecting plate 220 between the upper cross beam 210 and the vehicle frame beam 100, the strength of the vehicle frame as a whole can be improved.

[0119] In some embodiments, the upper cross beam 210 is sequentially in surface contact with the first connecting plate 220 and the frame beam 100; wherein the length direction of the frame beam 100 is perpendicular or inclined to the length direction of the upper cross beam 210.

[0120] By sequentially arranging the upper cross beam 210, the first connecting plate 220 and the frame beam 100 in surface contact, and arranging the length direction of the frame beam 100 to be perpendicular or inclined to the length direction of the upper cross beam 210, the connection stability of the frame is further improved.

[0121] In some embodiments, the length direction of the upper cross beam 210 is larger than the length direction of the first connecting plate 220.

[0122] By arranging the length direction of the upper cross beam 210 to be larger than the length direction of the first connecting plate 220, the length of the upper cross beam 210 can be ensured as much as possible, so as to ensure that the upper cross beam 210 is used as much as possible to increase the strength of the frame, and the first connecting plate 220 is used to block the liquid from entering the cabin space or flowing to the power assembly.

[0123] In some embodiments, the frame 10 further comprises a first sealing portion for sealing the gap between the upper cross beam 210, the first connecting plate 220 and the frame beam 100.

[0124] By arranging the first sealing portion to seal the gap between the upper cross beam 210, the first connecting plate 220 and the frame beam 100, and sequentially arranging the upper cross beam 210, the first connecting plate 220 and the frame beam 100 in surface contact, the sealing between the upper cross beam 210, the first connecting plate 220 and the frame beam 100 is formed, so as to form a sealing to ensure the sealing effect of the frame.

[0125] Exemplarily, the first sealing portion can be a spot welding sealant which can be applied at the lap joint surface between the upper cross beam 210, the first connecting plate 220 and the frame beam 100.

[0126] It should be noted that the upper cross beam 210 can be configured as a T-shaped structure, and the first connecting plate 220 can also be configured as a T-shaped structure similar to the upper cross beam 210. One first connecting plate 220 is arranged at each of the left and right ends of the upper cross beam 210, and the first connecting plate 220 is connected with the upper cross beam 210 and also connected with the front section of the frame beam 100 (i.e. the longitudinal beam) in a sealed manner.

[0127] In some embodiments, the first connecting plate 220 has a first portion extending in a first direction, which is used to provide a lap joint structure for mounting the frame beam 100.

[0128] The first connecting plate 220 is connected with the frame beam 100 in the first direction through the lap joint structure provided by the first part of the first connecting plate 220 and the frame beam 100.

[0129] In some embodiments, the upper cross beam assembly 200 further comprises a second connecting plate 230, and the frame 10 further comprises a middle floor 300.

[0130] The second connecting plate 230 is connected with the upper cross beam 210 and the first connecting plate 220 respectively, and the middle floor 300 is used to form an out-of-cabin space with the frame beam 100 independently of an in-cabin space, wherein a part of the middle floor 300 is connected with the second connecting plate 230 to make the liquid discharge flow channel 100a and the liquid guide flow channel 100b independent of the in-cabin space.

[0131] By connecting the part of the middle floor 300 with the second connecting plate 230, the effect of connecting the middle floor 300 to the front cross beam is achieved, and at the same time, the middle floor 300 is used to form an out-of-cabin space with the frame beam 100 independently of the in-cabin space, so that the liquid discharge flow channel 100a and the liquid guide flow channel 100b are independent of the in-cabin space, a second sealing is further formed, and in cooperation with the first sealing, the liquid in the out-of-cabin space cannot enter the in-cabin space, further ensuring the overall sealing effect of the frame 10.

[0132] In some embodiments, the frame 10 further comprises a rear floor 400 and a lower cross beam assembly 500.

[0133] The rear floor 400 is used to form the in-cabin space, and the lower cross beam 510 is connected with the rear floor 400 and the frame beam 100, wherein a part of the rear floor 400 is located between the frame beam 100 and the middle floor 300, so that the rear floor 400, the lower cross beam assembly 500, the upper cross beam assembly 200 and the middle floor 300 form a ring-shaped connected force transfer structure.

[0134] By providing the rear floor 400 and the lower cross beam assembly 500, the lower cross beam assembly 500 is connected with the rear floor 400 and the frame beam 100, and at the same time, a part of the rear floor 400 is located between the frame beam 100 and the middle floor 300, so that the rear floor 400, the lower cross beam assembly 500, the upper cross beam assembly 200 and the middle floor 300 form a ring-shaped connected force transfer structure, which can further increase the structural strength and crashworthiness, and at the same time, the lower cross beam 510 is not in communication with the in-cabin space.

[0135] The cavity defined by the force transfer structure of the annular connection between the middle floor 300, the rear floor 400, the rear section of the frame beam 100 and the lower cross beam assembly 500 is defined as a wet area, and the connection between the middle floor 300, the rear floor 400, the rear section of the frame beam 100 and the lower cross beam 510 in this area is sealed by normal glue sealing.

[0136] It should be noted that the cavity defined by the force transfer structure of the annular connection between the middle floor 300, the rear floor 400, the rear section of the frame beam 100 and the lower cross beam assembly 500 is an open cavity.

[0137] In some embodiments, the lower cross beam assembly 500 comprises a lower cross beam 510.

[0138] The lower cross beam 510 is used to form an out-of-cabin space with the middle floor 300 and the frame beam 100, wherein the lower cross beam 510 is located on the side of the middle floor 300 away from the power assembly.

[0139] The lower cross beam 510 of the present application is connected to the frame beam 100 through a third connecting plate 520, thereby realizing the connection between the lower cross beam 510 and the frame beam 100, and the third connecting plate 520 can also form part of the force transfer structure, further improving the impact force transfer of the frame after being impacted, and further improving the strength of the frame.

[0140] In some embodiments, a second sealing portion is further provided between the middle floor 300 and the upper cross beam assembly 200.

[0141] By providing the second sealing portion to seal the gap between the middle floor 300 and the upper cross beam assembly 200, the sealing effect of the frame can be further ensured.

[0142] Exemplarily, the second sealing portion can adopt a skeleton epoxy foam adhesive, the skeleton being shaped according to the sealing area, and a high-temperature foaming process being used to form a sealing structure.

[0143] Specifically, the middle floor 300 can be connected to the second connecting plate 230 of the upper cross beam assembly 200, and the middle floor 300 can be connected to the part of the second connecting plate 230 extending to the front end along the first direction, thereby forming the connection between the middle floor 300 and the upper cross beam assembly 200.

[0144] It can be understood that the middle floor 300 and the second connecting plate 230 also form a surface contact, and the second sealing portion is filled in the part where the two form a surface contact, thereby realizing the sealed connection between the middle floor 300 and the second connecting plate 230.

[0145] In some embodiments, the frame further comprises a rocker inner panel 600 and a mounting member 700.

[0146] The threshold inner plate 600 is used to be connected with the upper cross beam assembly 200 and the frame beam 100, and the mounting member 700 is used to provide a suspended mounting structure connected with the power assembly of the vehicle 1, wherein the mounting member 700 is connected with the threshold inner plate 600, and the projection of the mounting member 700 is located in the projection of the threshold inner plate 600 in the second direction.

[0147] By setting the connection of the threshold inner plate 600 with the upper cross beam assembly 200 and the frame beam 100, the mounting member 700 is used to provide a suspended mounting structure connected with the power assembly of the vehicle 1, and the mounting member 700 is connected with the threshold inner plate 600, so as to realize the connection of the mounting member 700 with the upper cross beam assembly 200 and the frame beam 100 through the threshold inner plate 600. This connection mode realizes the stable connection of the power assembly and the frame, and can also avoid damage to the power assembly caused by liquid.

[0148] It can be understood that the power assembly in the application is a power battery, and the frame in the application can be connected with the upper plate of the power battery pack. At this time, the integration of the battery and the frame is realized, and the sealing space in the cabin is sealed by the sealing glue between the battery upper cover and the sealing surface formed by the threshold and the upper cross beam 210 and the lower cross beam 510.

[0149] Exemplarily, the mounting member 700 serves as a sealing member between the power battery and the threshold inner plate 600, and realizes the sealing between the two.

[0150] Specifically, the shape of the mounting member 700 can be adjusted according to the position of the liquid discharge channel on the frame beam 100, so as to ensure that the liquid discharge channel communicates with the space outside the cabin.

[0151] It should be noted that the part between the threshold inner plate 600, the front section of the frame beam 100 and the first connecting plate 220 is in surface contact, and the part is sealed by spot welding sealing glue or adhesive sealing glue, thereby forming a third sealing, and further improving the sealing effect of the whole frame.

[0152] In some embodiments, the frame 10 further comprises a third sealing part.

[0153] By setting the third sealing part to block the liquid in the space outside the cabin from entering the space inside the cabin, the third sealing part is connected between the mounting member 700 and the power assembly of the vehicle 1 to seal the gap between the mounting member 700 and the power assembly of the vehicle 1, thereby further improving the sealing performance of the whole frame.

[0154] Exemplarily, the third sealing part can be configured as a sealing ring, thereby further improving the sealing performance between the power battery and the threshold inner plate 600.

[0155] In some embodiments, the frame further comprises a reinforcing plate 800.

[0156] The reinforcing plate 800 is arranged at the positions where the frame beam 100 and the rocker inner plate 600 are connected, and can further increase the overall strength of the frame.

[0157] When the frame beam 100 of the present application is arranged as a longitudinal beam and connected with other beam structures on the frame and forms an integral whole with the power battery pack, the frame beam 100 is arranged obliquely to the horizontal plane, at this time, the beam space of the frame beam 100 itself serves as a liquid guide channel 100b for the liquid to enter the frame beam 100 from the space outside the cabin, and then is discharged to the outside of the frame beam 100 along the liquid discharge channel 100a of the frame beam 100, that is, the space outside the cabin, and the upper cross beam 210, the lower cross beam 510, the middle floor and the rear floor 400 physically isolate the space inside the cabin and the space outside the cabin.

[0158] The frame structure of the present application optimizes all the lap joints, so that all the lap joints and gaps can be completed by gluing at a normal coating station, the cavity partition can be reduced or even cancelled, the frame can realize 100% sealing, and the cost is saved while meeting the sealing, and the strength of the body battery pack integrated structure is further increased.

[0159] When the frame 10 of the present application adopts the frame beam 100 as a longitudinal beam, the liquid guide channel 100b thereof can play a certain buffering role on water when the water level is deep, so as to avoid the problem that water directly flows to the liquid discharge channel 100a and causes excessive water pressure.

[0160] According to a third aspect of the present application, referring to Figure 11 , a vehicle 1 is provided, which comprises the frame beam 100 as above or the frame 10 as above.

[0161] The vehicle 1 comprises the frame beam 100 as above, and thus has all the beneficial effects of the frame beam 100 as above, which will not be repeated here.

[0162] The vehicle 1 comprises the frame 10 as above, and thus has all the beneficial effects of the frame 10 as above, which will not be repeated here.

[0163] The vehicle 1 can be a fuel automobile, a plug-in hybrid electric vehicle or a new energy vehicle, which is not limited in the present application.

[0164] In some embodiments, the power assembly of the vehicle 1 comprises a power battery pack.

[0165] The power assembly of the vehicle 1 comprises the power battery pack, and thus the shell outside the power battery pack serves as a part of the space inside the cabin.
