[0002] With the development of the national economy and the continuous improvement of living standards, vehicles are becoming increasingly important in daily life and travel, and vehicle driving safety is a key consideration during vehicle production. Currently, high-voltage components in vehicles are installed on the rear floor due to space constraints. However, in the event of a high-speed rear-end collision, the rear of the vehicle body undergoes significant deformation, which can lead to short circuits in the high-voltage components, potentially causing fires and affecting passenger safety. Therefore, there is room for improvement. Utility Model Content

[0024] The high-voltage components in existing vehicles are installed on the rear floor due to space constraints. However, in the event of a high-speed rear-end collision, the rear of the vehicle can deform significantly, causing the high-voltage components to be compressed and short-circuited, which could lead to a fire and affect the safety of the vehicle. There is room for improvement in this regard.

[0025] The following is for reference. Figures 1-7 The vehicle frame assembly described in this utility model embodiment has a simple structure and low installation cost. It can avoid squeezing the charger 102, thereby ensuring the reliability of the charger 102 and improving the safety of vehicle passengers.

[0026] like Figures 1-7 As shown, a vehicle frame assembly according to an embodiment of the present invention includes: a floor longitudinal beam 2 and a charger mounting bracket 1.

[0027] The floor beam 2 is supported under the floor 101, and the charger mounting bracket 1 is installed above the floor 101. The charger mounting bracket 1 includes a first connecting part 11, an intermediate deformable part 12 and a second connecting part 13 connected in sequence along the longitudinal direction. The first connecting part 11 is used to connect to the charger 102, and the second connecting part 13 is used to connect to the floor beam 2. The intermediate deformable part 12 is configured to extend upward in the longitudinal direction so that a height difference is formed between the first connecting part 11 and the second connecting part 13.

[0028] Among them, the charger 102 is the core component of the vehicle. The charger 102 can convert the externally input AC power into the DC power required by the power battery. In this process, it works in conjunction with the battery management system to intelligently adjust the charging voltage and current, and provide overvoltage and overcurrent protection to ensure that the vehicle's battery can be charged safely and efficiently.

[0029] Specifically, the frame assembly is provided with a floor longitudinal beam 2, which extends longitudinally along the vehicle. The vehicle floor 101 can be installed above the floor longitudinal beam 2, that is, the floor longitudinal beam 2 can support the floor 101. The floor longitudinal beam 2 can also provide mounting points for seats, etc. When the vehicle is involved in a collision, the collision force can be transmitted through the floor longitudinal beam 2 to weaken the effect of the force and ensure the safety of the vehicle. The frame assembly is also provided with a charger mounting bracket 1, which is used to install a charger 102. The charger mounting bracket 1 can be connected to the floor longitudinal beam 2 through connectors, etc., and the charger 102 can be connected to the charger mounting bracket 1 through connectors, etc., so that the charger 102 can be installed above the floor 101.

[0030] Furthermore, the charger mounting bracket 1 is provided with a first connecting part 11, an intermediate deformable part 12, and a second connecting part 13. The first connecting part 11, the intermediate deformable part 12, and the second connecting part 13 are connected sequentially along the longitudinal direction, that is, the intermediate deformable part 12 is connected between the first connecting part 11 and the second connecting part 13. The first connecting part 11 is provided with connecting holes, etc. The charger 102 is provided with a connecting bracket 103 protruding outward along the body. The connecting bracket 103 may also be provided with connecting holes. Connectors can be sequentially inserted into the two connecting holes so that the charger 102 and the first connecting part 11 can be detachably connected, which is convenient for installation. Moreover, when either the charger 102 or the charger mounting bracket 1 is damaged, only the damaged part needs to be replaced, saving maintenance costs.

[0031] Furthermore, the second connecting part 13 and the floor longitudinal beam 2 can also be provided with connecting holes, and the floor 101 is provided with through holes. The connector can be sequentially inserted into the connecting holes and through holes of the second connecting part 13 to connect with the connecting holes of the floor longitudinal beam 2. In this way, the charger mounting bracket 1 can be installed on the floor longitudinal beam 2, which is convenient for installation. Moreover, if one of the floor longitudinal beam 2 and the charger mounting bracket 1 is damaged, only the damaged part needs to be replaced, saving maintenance costs.

[0032] In addition, the intermediate deformable portion 12 is configured to extend upward in a longitudinal direction, that is, the intermediate deformable portion 12 can be configured to extend upward in a longitudinal direction and forward in a forward inclination, or the intermediate deformable portion 12 can be configured to extend upward in a longitudinal direction and backward in a backward inclination, thereby making the first connecting portion 11 located above the second connecting portion 13 in the horizontal direction, that is, a height difference is formed between the first connecting portion 11 and the second connecting portion 13.

[0033] Thus, when the charger 102 is installed on the floor longitudinal beam 2 via the charger mounting bracket 1, there is a gap between the bottom of the charger 102 and the floor 101. When the rear of the vehicle collides, the charger mounting bracket 1 can deform upward, thereby allowing the charger 102 to move upward and avoid squeezing the charger 102. This can prevent the charger 102 from short-circuiting, catching fire, or other situations, ensuring the reliability of the charger 102 and improving the safety of the vehicle. In addition, the charger mounting bracket 1 has a simple structure and low installation cost.

[0034] According to the vehicle frame assembly of this utility model embodiment, by providing a middle deformable part 12 that extends longitudinally upward in an inclined manner in the charger mounting bracket 1, when the charger 102 is mounted above the floor 101 through the charger mounting bracket 1, there can be a height difference between the charger 102 and the floor 101. As a result, when the rear of the vehicle is impacted, the charger mounting bracket 1 can deform upward, allowing the charger 102 to move upward, avoiding compression of the charger 102. This can prevent the charger 102 from short-circuiting, catching fire, or other situations, ensuring the reliability of the charger 102 in use, thereby improving the vehicle's passenger safety, resulting in better performance and a wider range of applications.

[0035] In some embodiments, there are two charger mounting brackets 1, which are distributed longitudinally at intervals and are respectively connected to the charger 102.

[0036] Specifically, the charger 102 can be mounted above the floor 101 via the charger mounting bracket 1, and as follows: Figure 1 As shown, there can be two charger mounting brackets 1, each extending laterally, and the two charger mounting brackets 1 are spaced apart longitudinally. Each charger mounting bracket 1 can be connected to the charger 102, so that the charger 102 can be installed on the floor longitudinal beam 2 at two points along the longitudinal direction through the charger mounting bracket 1, ensuring the installation reliability of the charger 102. When the vehicle is moving and the charger 102 has a forward or backward displacement tendency due to inertial force, the charger mounting bracket 1 located on the front or rear side can support the charger 102, ensuring the installation stability of the charger 102.

[0037] Furthermore, each charger mounting bracket 1 can be provided with multiple connection holes, and the charger 102 can be provided with multiple corresponding connecting brackets 103. The multiple connection holes and multiple connecting brackets 103 are provided one-to-one, so that multiple parts of the charger 102 can be connected to the charger mounting bracket 1 through connectors, ensuring connection reliability. When there is a relative displacement tendency between the charger 102 and the charger mounting bracket 1, the connecting brackets 103 and the connection holes of the charger mounting bracket 1 will be subjected to force. Providing multiple connection holes and multiple connecting brackets 103 can disperse the force, thereby weakening the effect of the force and extending the service life.

[0038] In some embodiments, in the two charger mounting brackets 1, the middle deformable portion 12 of the charger mounting bracket 1 located on the front side is configured to extend forward and upward in a longitudinal direction, and the middle deformable portion 12 of the charger mounting bracket 1 located on the rear side is configured to extend backward and upward in a longitudinal direction.

[0039] Specifically, there are two charger mounting brackets 1, which are spaced apart longitudinally, i.e., one charger mounting bracket 1 is located on the front side and the other is located on the rear side, and so on. Figure 1 As shown, the middle deformable portion 12 of the charger mounting bracket 1 located on the front side is constructed to extend forward and upward in a longitudinal direction, and the middle deformable portion 12 of the charger mounting bracket 1 located on the rear side is constructed to extend backward and upward in a longitudinal direction, so that the distance between the bottoms of the two middle deformable portions 12 is small, and the distance between the tops of the two middle deformable portions 12 is large, that is, the distance between the two middle deformable portions 12 gradually increases in the direction from bottom to top.

[0040] Thus, when a collision occurs at the front or rear of the vehicle, the vehicle frame assembly will deform longitudinally. At this time, the two charger mounting brackets 1 will deform upward under longitudinal compression, thereby lifting the charger 102 connected above the charger mounting bracket 1 to avoid squeezing the charger 102, thereby avoiding risks such as short circuits and fires, and improving safety in use.

[0041] Furthermore, the height difference between the first connecting part 11 and the second connecting part 13 can be set to x, and x satisfies: 15mm≤x≤25mm, that is, the height difference x between the first connecting part 11 and the second connecting part 13 can be set to 15mm, 15.5mm, 16mm, 16.5mm, 17mm, 17.5mm, 18mm, 18.5mm, 19mm, 19.5mm, 20mm, 20.5mm, 21mm, 21.5mm, 22mm, 22.5mm, 23mm, 23.5mm, 24mm, 24.5mm, 25mm, or any value between 15mm and 25mm. In this embodiment, the height difference x between the first connecting part 11 and the second connecting part 13 is set to 20mm.

[0042] Setting the height difference x between the first connecting part 11 and the second connecting part 13 to satisfy 15mm≤x≤25mm can prevent the length of the intermediate deformable part 12 from being too long due to an excessively large height difference, which would result in poor structural strength of the charger mounting bracket 1 and easy deformation. It can also prevent the charger mounting bracket 1 from deforming less in the event of a collision due to a small height difference, which would result in the charger 102 being squeezed. Thus, setting the height difference x between the first connecting part 11 and the second connecting part 13 to satisfy 15mm≤x≤25mm can ensure the reliability of the charger mounting bracket 1 in both installation and use.

[0043] In some embodiments, the charger mounting bracket 1 is provided with longitudinally extending reinforcing ribs 14, and / or, the first connecting portion 11 of the charger mounting bracket 1 is provided with a weight-reducing groove 111. This means that the charger mounting bracket 1 may only have longitudinally extending reinforcing ribs 14, or the charger mounting bracket 1 may only have weight-reducing grooves 111 at the first connecting portion 11, or the charger mounting bracket 1 may have both longitudinally extending reinforcing ribs 14 and weight-reducing grooves 111. In this embodiment, the charger mounting bracket 1 is provided with longitudinally extending reinforcing ribs 14, and the first connecting portion 11 of the charger mounting bracket 1 is provided with weight-reducing grooves 111.

[0044] Specifically, such as Figures 1-2 As shown, the reinforcing rib 14 is configured to extend longitudinally, that is, the reinforcing rib 14 is configured to extend along the distribution direction of the two charger mounting brackets 1, thereby improving the overall structural strength of the charger mounting bracket 1 and preventing the deformation of the middle deformation part 12 during normal use. In addition, there are multiple reinforcing ribs 14, which are distributed at intervals along the length direction of the charger mounting bracket 1, thereby improving the overall structural strength of the charger mounting bracket 1 and ensuring the reliability of use.

[0045] Furthermore, such as Figures 1-2 As shown, the charger mounting bracket 1 is also provided with a weight reduction groove 111. The weight reduction groove 111 is provided in the first connecting part 11. The weight reduction groove 111 of the charger mounting bracket 1 located on the front side is open to the front side, and the weight reduction groove 111 of the charger mounting bracket 1 located on the rear side is open to the rear side. The weight reduction groove 111 is distributed at intervals from the connecting hole, thereby improving the weight reduction while ensuring the reliability of the connection, so as to improve the vehicle's range performance.

[0046] In some embodiments, there are multiple floor longitudinal beams 2, which are distributed laterally spaced apart. At least two of the multiple floor longitudinal beams 2 are configured as mounting beams. The length direction of the charger mounting bracket 1 extends laterally, and the charger mounting bracket 1 is connected to at least two mounting beams respectively.

[0047] Specifically, multiple floor longitudinal beams 2 are provided, that is, two, three, or four floor longitudinal beams 2 can be provided, etc. In this embodiment, for example... Figure 3 As shown, there are four floor longitudinal beams 2. The multiple floor longitudinal beams 2 are all extended longitudinally and distributed laterally. At least two of the multiple floor longitudinal beams 2 are configured as installation beams. That is, two, three or all of the multiple floor longitudinal beams 2 can be configured as installation beams. In this embodiment, two of the multiple floor longitudinal beams 2 can be configured as installation beams, and the two installation beams are located in the middle of the multiple floor longitudinal beams 2.

[0048] Furthermore, the charger mounting bracket 1 extends laterally along the vehicle, and each of the two charger mounting brackets 1 is connected to at least two mounting longitudinal beams, thereby enabling at least two mounting longitudinal beams to support the charger mounting bracket 1 laterally, ensuring the reliability of the charger mounting bracket 1. Since the at least two mounting longitudinal beams are located in the middle of multiple floor longitudinal beams 2, the charger 102 can be mounted in the middle of the vehicle via the charger mounting bracket 1, keeping the charger 102 away from the sides of the vehicle. This avoids direct impact force on the charger 102, ensuring the reliability of the charger 102 and driving safety.

[0049] In some embodiments, the mounting beam includes a first sub-segment 21, a connecting segment 22, and a second sub-segment 23 connected sequentially in the front-to-back direction, with the connecting segment 22 inclined outward from front to back.

[0050] Specifically, the charger mounting bracket 1 is installed on the mounting longitudinal beam, and as follows: Figure 3 As shown, the mounting longitudinal beam is provided with a first sub-segment 21, a connecting segment 22, and a second sub-segment 23. The first sub-segment 21, the connecting segment 22, and the second sub-segment 23 are connected sequentially along the longitudinal direction. The connecting segment 22 is connected between the first sub-segment 21 and the second sub-segment 23. The first sub-segment 21 is located at the front of the mounting longitudinal beam, and the second sub-segment 23 is located at the rear of the mounting longitudinal beam. The connecting segment 22 is constructed to be inclined outward from front to back. That is, when the front of the vehicle collides, the collision force can be transmitted along the mounting longitudinal beam. After the connecting segment 22 is subjected to force, the rear end of the connecting segment 22 will deform outward, thereby allowing the second sub-segment 23 to deform outward.

[0051] The second sub-segment 23 is connected to the charger mounting bracket 1, i.e. Figure 3 As shown, the charger mounting bracket 1 can be installed on the second sub-section 23. When the second sub-section 23 deforms to both sides of the vehicle, the charger mounting bracket 1 can be separated from the second sub-section 23, thereby preventing the second sub-section 23 from squeezing the charger 102 and ensuring the reliability and safety of the charger 102.

[0052] In other embodiments, such as Figure 3As shown, the first sub-segment 21 is also provided with a bending portion 211. The bending portion 211 can be constructed as a bending groove. The bending groove extends laterally and is recessed downward on the upper surface of the first sub-segment 21. This allows the first sub-segment 21 to bend and deform at the bending portion 211 when the collision force is transmitted to it, thereby reducing the collision force transmitted to the second sub-segment 23. This reduces the force on the charger 102 and ensures the safety of the charger 102. Furthermore, the front of each of the multiple floor longitudinal beams 2 can be provided with a bending portion 211, so that when the front of the vehicle collides, the front of the floor longitudinal beam 2 can deform to weaken the rearward transmission of the collision force and reduce the intrusion of the floor longitudinal beam 2 into the passenger compartment, thereby improving passenger safety.

[0053] In other embodiments, such as Figure 4 As shown, a reinforcing plate 231 is provided inside the rear end of the second sub-segment 23. The reinforcing plate 231 extends along the length of the second sub-segment 23. When the rear of the vehicle collides, the collision force is first applied to the rear end of the second sub-segment 23. By providing a reinforcing plate 231 to the rear end of the second sub-segment 23, the structural strength of the rear end of the second sub-segment 23 can be improved, thereby reducing the deformation of the second sub-segment 23 and avoiding squeezing of the charger 102 installed on the second sub-segment 23, thus improving the safety of the charger 102 in use.

[0054] In some embodiments, the frame assembly further includes a rear sill beam 3, which is connected to the rear end of the floor 101 and located above the floor longitudinal beam 2. The rear sill beam 3 has a first energy-absorbing element 31 disposed inside it, which is distributed longitudinally in correspondence with the floor longitudinal beam 2 on which the charger mounting bracket 1 is installed.

[0055] Specifically, the chassis assembly also includes a rear sill beam 3, such as Figure 3 and Figure 7 As shown, the rear sill beam 3 extends laterally along the vehicle. The rear sill beam 3 is connected to the rear end of the floor 101 and is located above the floor longitudinal beam 2. Multiple floor longitudinal beams 2 can be connected and supported under the rear sill beam 3 to ensure the reliability of the rear sill beam 3. The rear sill beam 3 has a cavity inside. When the rear of the vehicle collides, the cavity inside the rear sill beam 3 can buffer the collision force, thereby improving the safety of use.

[0056] Furthermore, such as Figure 5 and Figure 7As shown, a first energy-absorbing component 31 is also provided inside the rear sill beam 3. The first energy-absorbing component 31 can be connected to the inner wall of the rear sill beam 3 by welding or other means. Multiple floor longitudinal beams 2 are provided. The charger mounting bracket 1 is installed above at least two floor longitudinal beams 2. The first energy-absorbing component 31 is provided inside the rear sill beam 3 and is distributed longitudinally in a one-to-one correspondence with the floor longitudinal beams 2 on which the charger mounting bracket 1 is installed. This is so that when the rear of the vehicle collides, the first energy-absorbing component 31 can weaken the collision force, thereby reducing the collision force transmitted to the charger 102 through the floor longitudinal beams 2, thus ensuring the reliability of the charger 102 and the driving safety of the vehicle.

[0057] In some embodiments, the first energy-absorbing member 31 includes a connecting portion 311 and two supporting portions 312. The connecting portion 311 is connected between the two supporting portions 312. The connecting portion 311 abuts against the rear side of the inner wall of the rear sill beam 3, and the two supporting portions 312 abut against the front side of the inner wall of the rear sill beam 3, so that the first energy-absorbing member 31 and the front side of the inner wall of the rear sill beam 3 together define the first buffer cavity 32, wherein the two supporting portions 312 are inclined in a direction away from each other.

[0058] Specifically, a first energy-absorbing element 31 is provided inside the rear sill beam 3, and as follows: Figure 6 As shown, the first energy-absorbing member 31 is provided with a connecting part 311 and two supporting parts 312. The connecting part 311 is connected between the two supporting parts 312. When the first energy-absorbing member 31 is installed in the rear door sill beam 3, the side of the connecting part 311 away from the supporting part 312 can press against the rear side of the inner wall of the rear door sill beam 3, and the two supporting parts 312 extend forward so that the end of the two supporting parts 312 away from the connecting part 311 can press against the front side of the inner wall of the rear door sill beam 3. That is, the first energy-absorbing member 31 can press against the front and rear sides of the rear door sill beam 3 in the longitudinal direction to improve the structural strength of the rear door sill beam 3.

[0059] Furthermore, when the first energy-absorbing component 31 is installed inside the rear sill beam 3, the first energy-absorbing component 31 and the front side of the inner wall of the rear sill beam 3 can jointly define the first buffer cavity 32, so that when the rear of the vehicle is hit by a collision, the collision force can be weakened through the first buffer cavity 32 of the first energy-absorbing component 31, thereby reducing the collision force transmitted to the floor longitudinal beam 2, reducing the deformation of the floor longitudinal beam 2, and thus avoiding squeezing the charger 102, ensuring the safety of the charger 102 in use.

[0060] In addition, the two support portions 312 are located on both sides of the connecting portion 311 in the lateral direction, and the two support portions 312 are inclined in the direction away from each other, so that the distance between the ends of the two support portions 312 closer to the connecting portion 311 is relatively small, and the distance between the ends of the two support portions 312 farther away from the connecting portion 311 is relatively large. This allows the two support portions 312 to deform in the direction away from each other after the first energy-absorbing member 31 is subjected to the impact force, thereby buffering the impact force and improving the buffering effect.

[0061] In some embodiments, the frame assembly further includes a rear bumper beam 4, which extends laterally and is located behind a plurality of floor longitudinal beams 2. At least two second energy-absorbing members 41 spaced laterally are provided on the rear side of the rear bumper beam 4. A second energy-absorbing cavity is formed inside the second energy-absorbing member 41, and the cross-sectional structure of the second energy-absorbing cavity in the vertical direction gradually decreases from front to rear.

[0062] Specifically, the chassis assembly is also equipped with a rear anti-collision beam 4, which extends laterally and is installed at the rear of the vehicle and located behind multiple floor longitudinal beams 2. When the vehicle is involved in a rear-end collision, the rear anti-collision beam 4 can absorb and disperse the impact force through its own deformation, and can transfer the impact force to the main longitudinal beams located on both sides of the floor connected to it, thereby reducing the deformation damage of the chassis assembly and reducing maintenance costs.

[0063] Furthermore, the rear bumper beam 4 is also provided with a second energy-absorbing component 41. The second energy-absorbing component 41 is installed on the rear side of the rear bumper beam 4, and multiple second energy-absorbing components 41 can be provided. The multiple second energy-absorbing components 41 are distributed laterally spaced. A second energy-absorbing cavity is formed inside the second energy-absorbing component 41. That is, when the rear of the vehicle is involved in a collision, the collision force acts on the second energy-absorbing component 41 first. When the second energy-absorbing component 41 is deformed, the second energy-absorbing cavity can buffer the impact force to weaken it. Providing multiple second energy-absorbing components 41 can weaken the impact force at multiple positions on the rear side of the rear bumper beam 4, thereby improving the reliability of use.

[0064] This utility model also proposes a vehicle.

[0065] The vehicle according to the embodiments of the present invention includes the frame assembly of any of the above claims.

[0066] According to the embodiment of this utility model, the vehicle is provided with a frame assembly. The frame assembly has a longitudinally upwardly extending intermediate deformable part 12 provided in the charger mounting bracket 1. When the charger 102 is mounted above the floor 101 through the charger mounting bracket 1, there can be a height difference between the charger 102 and the floor 101. Therefore, when the rear of the vehicle is hit by a collision, the charger mounting bracket 1 can deform upward, so that the charger 102 can move upward, avoiding compression of the charger 102. This can prevent the charger 102 from short-circuiting, catching fire, etc., ensuring the reliability of the charger 102, improving the vehicle's passenger safety, and providing better performance and wider applicability.
