In the event of a collision of the vehicle, this arrangement can reduce the negative impact of the bracket assembly on the anti-collision performance of the longitudinal beam; at the same time, this arrangement also leaves space near the longitudinal beam to provide installation space for other structures.

[0006] In some embodiments, the support assembly includes a support body, and the support body is used to support the low-voltage energy storage device; a connecting portion is provided on the support body, and the connecting portion is connected to the crossbeam.

[0016] In some embodiments, the bracket body further includes two side plates, which are arranged on opposite sides of the support plate along the width direction of the frame.

[0017] In the technical solution of this embodiment, two side plates are provided to limit the displacement of the low-voltage energy storage device in the width direction of the frame through the two side plates, so as to better fix the low-voltage energy storage device on the support plate; at the same time, the two side plates can also protect both sides of the low-voltage energy storage device to reduce possible damage to the low-voltage energy storage device.

[0018] In some embodiments, the frame further includes a baffle; in the length direction of the frame, at least a portion of the baffle is located at the front side of the bracket assembly, and the baffle is spaced apart from the bracket assembly.

[0019] In the technical solution of this embodiment, a baffle is provided on the front side of the bracket assembly. When the front end of the vehicle is hit, the damaged structural parts of the vehicle are prone to collide with and cut the low-pressure energy storage device on the bracket assembly. Accordingly, a baffle is provided and at least a portion of the baffle is located on the front side of the bracket assembly to reduce the damage that may be caused to the low-pressure energy storage device by a vehicle collision.

[0020] In some embodiments, the baffle is connected to the beam and bracket assembly.

[0024] In some embodiments, in the height direction of the frame, a height dimension of the third portion is less than or equal to a height dimension of the bracket assembly.

[0025] In the technical solution of this embodiment, when the vehicle is hit, the damaged structural parts of the vehicle are prone to collide with the intersection of the front side and the upper side of the low-pressure energy storage device; accordingly, compared with the method of completely covering or covering a large area of ​​the low-pressure energy storage device with the outer shell, the height dimension of the third part is less than or equal to the height dimension of the bracket assembly, so that the baffle can not only protect the low-pressure energy storage device, but also reduce the space occupied by the baffle and reduce the weight of the baffle.

[0027] In the technical solution of this embodiment, the bracket assembly is connected to the support member base. Since the support member base is close to the longitudinal beam, and the bracket assembly is also connected to the cross beam, this arrangement enables both the cross beam and the longitudinal beam to share the gravity of the bracket assembly, so that the bracket assembly can be more stably fixed on the frame, and can also reduce deformation, tearing, etc. that may be caused by stress concentration at one or some connection parts of the bracket assembly.

[0028] In some embodiments, the support member base includes a fifth part connected to the support member body and a sixth part connected to the fifth part, the sixth part is bent relative to the fifth part and connected to the longitudinal beam; the support member base also includes a reinforcing rib connected to the fifth part and the sixth part.

[0029] The technical solution of this embodiment provides some specific structures of the support member base. Since the support member body is used to provide a fixed foundation for the vehicle's shock-absorbing structure, the support member body is easily subjected to greater forces. Accordingly, reinforcing ribs are provided on the support member base to further improve the stability of the connection between the support member and the longitudinal beam, and to improve the strength of the support member base. Since the bracket assembly is connected to the support member base, this arrangement also enables the support member base to better provide support for the bracket assembly.

[0030] In some embodiments, the bracket assembly is connected to the reinforcement rib.

[0031] In the technical solution of this embodiment, the bracket assembly is arranged on the reinforcing ribs so that the support member base can better provide support for the bracket assembly.

[0032] In some embodiments, the support member is a tower base, and the tower base is used for installing the shock absorbing structure.

[0033] In the technical solution of this embodiment, the support member is a tower base, so that the support member can provide a fixed foundation for the crossbeam and the bracket assembly, and can also serve as a tower base to provide an installation foundation for the shock-absorbing structure; this setting utilizes the inherent structure of the frame without the need to set up additional structures to provide a fixed foundation for the bracket assembly and the crossbeam, thereby simplifying the structure of the frame.

[0034] In a second aspect, some embodiments of the present application further provide a vehicle, comprising the frame provided by some embodiments of the first aspect; and a low-pressure energy storage device, wherein the low-pressure energy storage device is installed on a bracket assembly.

[0063] The frame is a frame structure that spans the front and rear axles of the vehicle, also known as the beam, which is the base of the vehicle. It is generally composed of two longitudinal beams and several cross beams, and is supported on the wheels through the suspension device, front axle, and rear axle.

[0064] The frame should generally have good strength and rigidity to withstand the load of the vehicle and the impact from the wheels. The function of the frame is to support and connect the various assemblies of the vehicle, keep the assemblies in a relatively correct position, and withstand various loads inside and outside the vehicle. The device by which the body of a locomotive or vehicle is elastically supported on the axle box, side frame or equalizing beam is referred to as a spring device or suspension device.

[0065] The low-voltage energy storage device is an important component of the vehicle's electrical system. It is mainly used to start the engine and provide power for systems such as audio, lighting, car computers, and air conditioning. The low-voltage energy storage device is generally installed in the vehicle and installed on the longitudinal beam of the front structure of the frame through a support bracket. However, in the event of a collision at the front end of the vehicle, the longitudinal beam is the main component in the vehicle for withstanding the impact of the collision. Installing the low-voltage energy storage device on the longitudinal beam may have a negative impact on the anti-collision performance of the longitudinal beam.

[0066] At the same time, in addition to the low-pressure energy storage device, the front structure of the frame is also equipped with other components such as a compressor and a heater. In order to maintain the anti-collision performance of the longitudinal beam, the installation space and installation position on the longitudinal beam are limited. Installing the low-pressure energy storage device on the longitudinal beam is also likely to occupy the installation space of other structures.

[0067] Based on the above considerations, in order to alleviate the problem that the low-pressure energy storage device is likely to have a negative impact on the collision performance of the longitudinal beam, the present application provides a frame, which is provided with a bracket assembly for installing the low-pressure energy storage device, and the bracket assembly is connected to the crossbeam and support member of the frame. At the same time, the bracket assembly is spaced apart from the longitudinal beam.

[0068] In such a frame, the bracket assembly is connected to the crossbeam and the support member at the same time, and the crossbeam and the support member are usually located at different positions of the frame, that is, different positions of the bracket assembly can be connected to different parts of the frame, and the bracket assembly can be connected to different sides or different structures of the frame, so that the bracket assembly can be connected to the frame more stably; at the same time, the bracket assembly is spaced apart from the longitudinal beam, that is, the bracket assembly is no longer installed on the longitudinal beam, and there is space between the bracket assembly and the longitudinal beam, thereby reducing the negative impact of the bracket assembly and the low-pressure energy storage device on the anti-collision performance of the longitudinal beam, and at the same time, it can also make room for the installation space of the longitudinal beam to make room for the installation position of the longitudinal beam for other structures that require higher installation strength and stability.

[0069] The vehicle frame disclosed in the embodiment of the present application can be used for the chassis of a vehicle, or can be directly installed on the body of a vehicle. The vehicle can be a pure electric vehicle, a fuel vehicle, an electric fuel hybrid vehicle, etc.

[0070] refer to Figure 1 , Figure 1 The schematic diagram of the structure of the vehicle 1000 provided in the embodiment of the present application is as follows. The vehicle 1000 may be a fuel vehicle, a gas vehicle or a new energy vehicle, and the new energy vehicle may be a pure electric vehicle, a hybrid vehicle or an extended range vehicle.

[0071] Figure 1 In the figure, the direction of the X-axis is the length direction of the vehicle 1000, which is also the moving direction of the vehicle 1000; the direction of the Y-axis is the width direction of the vehicle 1000.

[0072] In some embodiments, the vehicle 1000 includes a chassis and a body, the body is mounted on the chassis, and the chassis supports the body. The body is a partial structure mounted on the chassis to provide driving space and riding space, and to provide protection for power components, electrical components, etc. on the chassis.

[0073] First, refer to Figure 2 , Figure 3The embodiment of the present application provides a vehicle frame 100, including a longitudinal beam 10, a support member 20, a cross beam 30 and a bracket assembly 40. The support member 20 is connected to the longitudinal beam 10; the cross beam 30 is connected to the support member 20, and the length direction of the cross beam 30 is set at an angle with the length direction of the longitudinal beam 10; the bracket assembly 40 is used for installing a low-voltage energy storage device 200, the bracket assembly 40 is connected to the cross beam 30 and the support member 20, and the bracket assembly 40 is spaced apart from the longitudinal beam 10.

[0074] In the figure, the direction of the X-axis is the length direction of the frame 100, which is also the moving direction of the vehicle 1000; the direction of the Y-axis is the width direction of the frame 100, which is also the width direction of the vehicle 1000; and the direction of the Z-axis is the height direction of the frame 100.

[0075] The longitudinal beam 10 refers to the structure on the frame 100 that mainly plays a bearing role. The longitudinal beam 10 is mainly used to withstand various forces generated during the driving of the vehicle 1000, such as the weight of the vehicle body, the impact caused by uneven road surface, etc.; when the front end of the vehicle 1000 is hit, the longitudinal beam 10 can also provide rigidity for the vehicle 1000 to reduce the deformation of the front structure of the vehicle 1000, thereby protecting various structures of the front structure of the vehicle 1000; the longitudinal beam 10 can also provide a fixed foundation for the compressor, heater or other structures.

[0076] The longitudinal beam 10 may be an I-beam, a box beam or a beam of other shapes; the length direction of the longitudinal beam 10 is parallel to the length direction X of the vehicle 1000; the number of longitudinal beams 10 is usually two, but may be three or more; the material of the longitudinal beam 10 may include pure metal, composite metal or other materials.

[0077] The support member 20 refers to a structure on the frame 100 that is mainly used to provide a fixed foundation for the cross beam 30 and the bracket assembly 40; the support member 20 can also provide a fixed foundation for the suspension system or other structures. In this case, at least part of the support member 20 can extend above the wheel to facilitate the installation of structures such as springs and shock absorbers of the suspension system.

[0078] The support member 20 can be a columnar structure, or a plate structure, a frame structure, or a structure of other shapes. The support member 20 can be a rectangular structure, a cylindrical structure, or a structure of other regular shapes. The support member 20 can also be an L-shaped structure, a T-shaped structure, or a structure of other irregular shapes. The number of support members 20 can be one, or two or more. The material of the support member 20 can include pure metal, composite metal, or other materials.

[0079] The support member 20 is connected to the longitudinal beam 10. The support member 20 can be fixedly connected to the longitudinal beam 10 by welding, bonding or other means, and can be detachably connected to the longitudinal beam 10 by screwing, clamping or other means. The support member 20 and the longitudinal beam 10 can also be made into an integral body.

[0080] For example, in the front structure of the vehicle frame 100 , the number of the support members 20 may be two; when there are two longitudinal beams 10 and two support members 20 , the two support members 20 are connected to the two longitudinal beams 10 , respectively.

[0081] The cross beam 30 refers to the structure on the frame 100 that mainly plays a load-bearing role. Compared with the longitudinal beam 10, the cross beam 30 is mainly a lateral supporting structure of the frame 100. The cross beam 30 can cooperate with the longitudinal beam 10 to withstand various forces generated during the driving process of the vehicle 1000, such as the weight of the vehicle body, the impact caused by uneven road surface, etc. The cross beam 30 can also improve the torsional stiffness of the frame 100; the cross beam 30 can also provide a fixed foundation for the heat pump or other structures.

[0082] The crossbeam 30 may be an I-beam, a box beam or a beam of other shapes; the number of crossbeams 30 may be one, or two or more; the crossbeam 30 is connected to the support member 20, and the crossbeam 30 may be fixedly connected to the support member 20 by welding, bonding or other means, or may be detachably connected to the support member 20 by screwing, clamping or other means, and the crossbeam 30 and the support member 20 may also be integrally formed; the length direction of the crossbeam 30 is set at an angle to the length direction of the longitudinal beam 10, and the length direction of the crossbeam 30 may be perpendicular to the length direction of the longitudinal beam 10, that is, the length direction of the crossbeam 30 may be parallel to the width direction Y of the frame 100, and the length direction of the crossbeam 30 may also form other angles with the length direction of the longitudinal beam 10; the material of the crossbeam 30 may include pure metal, composite metal or other materials.

[0083] For example, when there are two longitudinal beams 10 and two supporting members 20 , both ends of the cross beam 30 can be connected to the two supporting members 20 respectively. This arrangement can improve the integrity of the frame 100 , thereby improving the overall strength and rigidity of the frame 100 .

[0084] The bracket assembly 40 refers to a structure in the frame 100 for carrying the low-pressure energy storage device 200. The low-pressure energy storage device 200 can be installed on the bracket assembly 40 to fix the position of the low-pressure energy storage device 200 in the vehicle 1000; the bracket assembly 40 may include a frame structure, or a box structure or other structure; the material of the bracket assembly 40 may include metal, plastic or other materials.

[0085] The low-voltage energy storage device 200 may be a lead-acid low-voltage energy storage device, a lithium iron phosphate low-voltage energy storage device, a nickel-metal hydride low-voltage energy storage device, or other types of low-voltage energy storage devices.

[0086] The bracket assembly 40 is connected to the cross beam 30 and the support member 20. The bracket assembly 40 can be fixedly connected to the cross beam 30 and the support member 20 by welding, bonding or other means. The bracket assembly 40 can also be detachably connected to the cross beam 30 and the support member 20 by screwing, clamping or other means. The connection method between the bracket assembly 40 and the cross beam 30 and the support member 20 can be the same or different; only one connection position can be set between the bracket assembly 40 and the cross beam 30, or two or more connection positions can be set; only one connection position can be set between the bracket assembly 40 and the support member 20, or two or more connection positions can be set.

[0087] The bracket assembly 40 is connected to the cross beam 30 and the support member 20 so that the bracket assembly 40 can be connected to different sides or different structures of the frame 100, and the cross beam 30 and the support member 20 can both play a role in supporting the bracket assembly 40, thereby improving the stability of the connection of the bracket assembly 40.

[0088] The bracket assembly 40 is spaced apart from the longitudinal beam 10, that is, the bracket assembly 40 does not contact the longitudinal beam 10, and the bracket assembly 40 is not installed on the longitudinal beam 10, so as to reduce the negative impact that the bracket assembly 40 may have on the anti-collision performance of the longitudinal beam 10, and can also reduce the installation position occupied by the bracket assembly 40 on the longitudinal beam 10; the bracket assembly 40 is spaced apart from the longitudinal beam 10 and can also form a gap between it and the longitudinal beam 10, the size of which can be set according to the position and size of other structures in the front structure of the vehicle 1000 to facilitate the installation and arrangement of other structures.

[0089] For example, in the height direction Z of the frame 100, the cross beam 30 is located above the longitudinal beam 10. At this time, the longitudinal beam 10, the cross beam 30 and the support member 20 can form a frame structure, and form a accommodating space in the frame structure. The bracket assembly 40, the compressor, the heater and other structures can be located in the accommodating space so that the longitudinal beam 10, the cross beam 30 and the support member 20 can provide protection for them; at this time, the bracket assembly 40 is located below the cross beam 30 and above the longitudinal beam 10.

[0090] In this embodiment, a bracket assembly 40 is provided for installing the low-pressure energy storage device 200, and the bracket assembly 40 is connected to the cross beam 30 and the support member 20, so that the bracket assembly 40 and the low-pressure energy storage device 200 can be installed on the frame 100 more stably; the bracket assembly 40 and the longitudinal beam 10 are spaced apart to reduce the negative impact of the bracket assembly 40 on the mechanical strength of the longitudinal beam 10. When the vehicle 1000 is hit, this arrangement can reduce the negative impact of the bracket assembly 40 on the anti-collision performance of the longitudinal beam 10; at the same time, this arrangement also leaves space near the longitudinal beam 10 to provide installation space for other structures.

When the low-pressure energy storage device 200 is installed on the support plate 411, the second portion 442 is bent toward the direction where the low-pressure energy storage device 200 is located. This arrangement can form a clamping space between the second portion 442 and the support plate 411.

[0120] refer to Figures 4 to 7 In some embodiments, the support body 41 further includes two side plates 412 , and the two side plates 412 are disposed on opposite sides of the support plate 411 along the width direction of the frame 100 .

[0121] The side plate 412 refers to a structure in the bracket body 41 for limiting the displacement of the low-voltage energy storage device 200 in the width direction Y of the frame 100.

[0123] For example, the two side plates 412 are respectively located on both sides of the low-pressure energy storage device housing 61 along the width direction Y to limit the displacement of the low-pressure energy storage device 200 in the width direction Y.

[0124] The side plate 412 may completely cover the side surface of the low-pressure energy storage device 200 , or may only cover a portion of the side surface of the low-pressure energy storage device 200 , so as to protect the low-pressure energy storage device 200 .

[0125] One end of the side plate 412 away from the support plate 411 can be connected to the beam 30 to connect the bracket assembly 40 to the beam 30; for example, the connecting portion 42 is arranged on the side of the side plate 412 away from the support plate 411, and the connecting portion 42 is formed by bending the support plate 411.

[0126] In this embodiment, two side plates 412 are provided to limit the displacement of the low-pressure energy storage device 200 in the width direction of the frame 100 through the two side plates 412, so as to better fix the low-pressure energy storage device 200 on the support plate 411; at the same time, the two side plates 412 can also protect both sides of the low-pressure energy storage device 200 to reduce possible damage to the low-pressure energy storage device 200.

[0127] refer to Figures 4 to 6 In some embodiments, the frame 100 further includes a baffle 50 ; in the length direction of the frame 100 , at least a portion of the baffle 50 is located on the front side of the bracket assembly 40 , and the baffle 50 is spaced apart from the bracket assembly 40 .

[0128] The baffle 50 refers to a structure in the frame 100 for protecting the low-pressure energy storage device 200. When the vehicle 1000 collides, damaged structural parts or other debris produced by the collision can be blocked by the baffle 50, thereby reducing the direct collision of debris with the low-pressure energy storage device 200. The baffle 50 can be connected to the bracket body 41, or it can be connected to the crossbeam 30, the support member 20 or other structures of the frame 100. The shape of the baffle 50 can be square, circular or other shapes, and the shape of the baffle 50 can also be set according to the shape of the low-pressure energy storage device 200. The material of the baffle 50 can include metal, plastic or other materials.

[0129] At least a portion of the baffle 50 is arranged on the front side of the bracket assembly 40 along the length direction X of the frame 100, that is, the baffle 50 can be entirely arranged on the front side of the bracket assembly 40. In this case, the baffle 50 is only used to block the collision of debris from the front side of the low-pressure energy storage device 200. The baffle 50 can also be only partially arranged on the front side of the bracket assembly 40, and the other portion can be arranged on the left side, right side, rear side, top side or other positions of the low-pressure energy storage device 200. When the front structure of the vehicle 1000 is hit, the damaged structural parts or other debris produced by the collision will mostly splash from the front side of the low-pressure energy storage device 200 to the low-pressure energy storage device 200, so this arrangement can specifically protect the low-pressure energy storage device 200 under similar working conditions.

[0130] The baffle 50 is spaced apart from the bracket assembly 40 , that is, there is a gap between the baffle 50 and the bracket assembly 40 . This arrangement can reduce the damage to the low-pressure energy storage device 200 caused by the deformation of the baffle 50 , so that the baffle 50 can better protect the low-pressure energy storage device 200 .

[0131] In this embodiment, a baffle 50 is provided on the front side of the bracket assembly 40. When the front end of the vehicle 1000 is hit, the damaged structural parts of the vehicle 1000 are easily collided with and cut the low-pressure energy storage device 200 on the bracket assembly 40. Accordingly, the baffle 50 is provided and at least a portion of the baffle 50 is located on the front side of the bracket assembly 40 to reduce the damage that may be caused to the low-pressure energy storage device 200 by a collision of the vehicle 1000.

[0132] refer to Figure 2 , Figures 4 to 6 In some embodiments, the baffle 50 is connected to the beam 30 and the bracket assembly 40 .

[0133] The baffle 50 is connected to the cross beam 30 so as to install the baffle 50 on the vehicle frame 100; the baffle 50 can be fixedly connected to the cross beam 30 by welding, bonding or other means, or can be detachably connected to the cross beam 30 by screwing, clamping or other means; there can be only one connection position between the baffle 50 and the cross beam 30, or there can be two or more connection positions.

[0134] The baffle 50 is also connected to the bracket assembly 40 to fix the relative position of the baffle 50 and the bracket assembly 40; because the baffle 50 is connected to the cross beam 30, the baffle 50 is connected to the bracket and can also play a role in assisting in fixing the bracket assembly 40 through the baffle 50, so as to further improve the stability of the bracket assembly 40 installed on the frame 100.

[0135] The connection position between the baffle 50 and the bracket assembly 40 can be located at the front side of the bracket assembly 40, or at the upper side or lower side of the bracket assembly 40 along the height direction Z of the frame 100, or at the left side or right side of the bracket assembly 40 along the width direction Y of the frame 100. The connection part between the baffle 50 and the bracket assembly 40 can also be located at other positions of the bracket assembly 40; the baffle 50 can be fixedly connected to the bracket assembly 40 by welding, bonding, etc., or can be detachably connected to the bracket assembly 40 by screwing, snapping, etc.; there can be only one connection position between the baffle 50 and the bracket assembly 40, or there can be two or more connection positions. When there are two or more connection positions between the baffle 50 and the bracket assembly 40, the multiple connection positions can be located on the same side of the bracket assembly 40, or on different sides of the bracket assembly 40.

[0136] For example, the baffle 50 is connected to the front side of the bracket body 41 by bolts, and there are two connection positions between the baffle 50 and the bracket body 41.

[0137] In this embodiment, the baffle 50 is connected to the bracket assembly 40 and the cross beam 30, so that the baffle 50 can be fixed more stably on the front side of the bracket assembly 40; at the same time, this arrangement enables the cross beam 30 to be indirectly connected to the bracket assembly 40 through the baffle 50, and can provide support for the bracket assembly 40 through the baffle 50, thereby further improving the stability of the bracket assembly 40.

[0138] refer to Figures 4 to 6 In some embodiments, the baffle 50 includes a third portion 51 and a fourth portion 52 connected to the third portion 51; in the length direction of the frame 100, the third portion 51 is located on the front side of the bracket assembly 40; in the height direction of the frame 100, the fourth portion 52 is located on the upper side of the bracket assembly 40.

[0139] The third portion 51 is a partial structure of the baffle 50, and the third portion 51 is located on the front side of the bracket assembly 40 along the length direction X of the frame 100 to block the collision of debris from the front side of the low-pressure energy storage device 200; the shape of the third portion 51 can be circular, or square, or other shapes; the third portion 51 can completely cover the front side of the low-pressure energy storage device 200, or can completely cover the front side of the bracket assembly 40, or the third portion 51 can only cover the low-pressure energy storage device 200 and part of the front side of the bracket assembly 40; because the baffle 50 is connected to the bracket assembly 40, the third portion 51 can be connected to the bracket assembly 40, or can not be connected to the bracket assembly 40.

[0140] Similar to the third part 51, the fourth part 52 is also a partial structure of the baffle 50. The fourth part 52 is arranged on the upper side of the bracket assembly 40 along the height direction Z of the frame 100 to block the collision of debris from the upper side of the low-pressure energy storage device 200; the shape of the fourth part 52 can be circular, or square or other shapes; the fourth part 52 can completely cover the upper side of the low-pressure energy storage device 200, or it can completely cover the upper side of the bracket assembly 40, and the fourth part 52 can also only cover the upper part of the low-pressure energy storage device 200 and the bracket assembly 40; because the baffle 50 is connected to the crossbeam 30, and the fourth part 52 is located on the upper side of the bracket assembly 40, the fourth part 52 can be connected only to the crossbeam 30, or it can be connected to the crossbeam 30 and the bracket assembly 40.

[0141] The fourth portion 52 is connected to the third portion 51 . The fourth portion 52 may be connected to the third portion 51 by welding, bonding, or the like. The fourth portion 52 and the third portion 51 may also be integrally formed.

[0142] Because the third portion 51 and the fourth portion 52 are respectively located on the front side and the upper side of the low-pressure energy storage device 200 and the bracket assembly 40, and the third portion 51 is connected to the fourth portion 52, the third portion 51 and the fourth portion 52 cooperate to prevent debris from colliding with at least a portion of the front side and at least a portion of the upper side of the low-pressure energy storage device 200 and the bracket assembly 40, and the third portion 51 and the fourth portion 52 cooperate to prevent debris from colliding with the intersection of the upper side and the front side of the low-pressure energy storage device 200.

[0143] When the front end of the vehicle 1000 is hit, the collision and cutting of the damaged structural parts of the vehicle 1000 on the low-pressure energy storage device 200 mainly come from the front side of the low-pressure energy storage device 200 and the upper part of the low-pressure energy storage device 200 close to the front side, that is, the collision area of ​​the damaged structural parts of the vehicle 1000 on the low-pressure energy storage device 200 is mainly located at the intersection of the front side and the upper side of the low-pressure energy storage device 200; accordingly, compared with the method of completely covering or covering a large area of ​​the low-pressure energy storage device 200 with a shell, in this embodiment, the third part 51 is located on the front side of the bracket assembly 40, and the fourth part 52 is located on the upper side of the bracket assembly 40, and the baffle 50 is arranged in the direction where the low-pressure energy storage device 200 is easily damaged, so as to protect the part of the low-pressure energy storage device 200 that is easily damaged by the baffle 50, thereby better protecting the low-pressure energy storage device 200.

[0144] refer to Figure 6 In some embodiments, in the height direction of the frame 100 , the height dimension of the third portion 51 is less than or equal to the height dimension of the bracket assembly 40 .

[0145] The height dimension of the bracket assembly 40 refers to the dimension of the bracket assembly 40 in the height direction Z of the frame 100, that is, the dimension shown by H in the figure. The height dimension of the bracket assembly 40 is positively correlated with the height of the low-voltage energy storage device 200.

[0146] The height dimension of the third portion 51 refers to the dimension of the third portion 51 in the height direction Z of the frame 100, which is the dimension shown by h in the figure; because the third portion 51 is located at the front side of the low-pressure energy storage device 200, the height dimension of the third portion 51 is positively correlated with the front side area of ​​the low-pressure energy storage device 200 that can be protected by the third portion 51, and the height dimension of the third portion 51 is also positively correlated with the volume and mass of the third portion 51.

[0147] The height dimension of the third part 51 can be equal to the height dimension of the bracket assembly 40. At this time, the third part 51 completely or substantially completely covers the front side of the low-pressure energy storage device 200 and the bracket assembly 40, so that the baffle 50 can better protect the low-pressure energy storage device 200.

[0148] The height dimension of the third part 51 may also be smaller than the height dimension of the bracket assembly 40. In this case, the third part 51 only covers the front side portions of the low-voltage energy storage device 200 and the bracket assembly 40, so that the baffle 50 can not only protect the low-voltage energy storage device 200, but also reduce the weight and space occupancy of the baffle 50, thereby reducing its load on the bracket assembly 40 and the beam 30, and reducing the load on the connection parts between the baffle 50 and the beam 30, and between the baffle 50 and the bracket assembly 40, thereby improving the connection stability between the baffle 50 and the beam 30, and between the baffle 50 and the bracket assembly 40.

[0149] In this embodiment, when the vehicle 1000 is hit, the damaged structural parts of the vehicle 1000 are likely to collide with the intersection of the front side and the upper side of the low-pressure energy storage device 200; accordingly, compared with the method of completely covering or covering a large area of ​​the low-pressure energy storage device 200 with the outer shell, the height of the third portion 51 is less than or equal to the height of the bracket assembly 40, so that the baffle 50 can not only protect the low-pressure energy storage device 200, but also reduce the space occupied by the baffle 50 and reduce the weight of the baffle 50.

[0150] refer to Figure 2 , Figure 3 , Figure 8 In some embodiments, the support member 20 includes a support member body 21 and a support member base 22 connected to the support member body 21, the support member body 21 is connected to the cross beam 30; the side of the support member base 22 away from the support member body 21 is connected to the longitudinal beam 10, and the bracket assembly 40 is connected to the support member base 22.

[0151] The support member body 21 refers to a structure in the support member 20 that is used to provide a fixed foundation for the cross beam 30, the bracket assembly 40 or other structures, and the support member base 22 refers to a structure in the support member 20 that is connected to the longitudinal beam 10; the support member body 21 is connected to the support member base 22, and the support member body 21 and the support member base 22 can be made in one piece, or can be connected by welding or other methods.

[0152] The side of the support member base 22 away from the support member body 21 is connected to the longitudinal beam 10 to connect the support member 20 to the longitudinal beam 10. At this time, in the height direction of the frame 100, the support member body 21, the support member base 22 and the longitudinal beam 10 are arranged in sequence from top to bottom; the support member base 22 can be fixedly connected to the longitudinal beam 10 by welding, bonding or other methods, and can also be detachably connected to the longitudinal beam 10 by screwing, riveting or other methods.

[0153] The support member body 21 is connected to the cross beam 30. When there are two support members 20, the two ends of the cross beam 30 are respectively connected to the two support member bodies 21. Because the support member body 21 is located on the side of the support member base 22 away from the longitudinal beam 10, that is, the support member body 21 is far away from the connection position between the longitudinal beam 10 and the support member base 22, the strength of the support member body 21 is relatively low. Therefore, connecting the cross beam 30 to the support member body 21 can improve the strength and stability of the support member body 21 and can improve the overall stability of the frame 100. For example, the cross beam 30 is connected to one end of the support member body 21 away from the longitudinal beam 10 to improve the strength and stability of the end of the support member body 21 away from the longitudinal beam 10.

[0154] The bracket assembly 40 is connected to the support member base 22. The bracket assembly 40 can be fixedly connected to the support member base 22 by welding, bonding or other methods, and can also be detachably connected to the support member base 22 by screwing, riveting or other methods; because the support member base 22 is close to the longitudinal beam 10, and the strength of the longitudinal beam 10 is relatively high, the bracket assembly 40 is connected to the support member base 22 so that the connection portion between the bracket assembly 40 and the support member 20 can be close to the longitudinal beam 10, thereby improving the strength and stability of the connection portion between the bracket assembly 40 and the support member 20; at the same time, compared with the support member body 21, the support member base 22 is farther away from the cross beam 30. This arrangement can also enable the cross beam 30 and the support member 20 to better disperse the gravity of the bracket assembly 40 and the low-pressure energy storage device 200, and reduce the problem of excessive local load caused by force concentration in a certain area.

[0155] In this embodiment, the bracket assembly 40 is connected to the support member base 22. Since the support member base 22 is closer to the longitudinal beam 10, and the bracket assembly 40 is also connected to the cross beam 30, this arrangement enables the cross beam 30 and the longitudinal beam 10 to share the gravity of the bracket assembly 40, so that the bracket assembly 40 can be more stably fixed on the frame 100, and can also reduce deformation, tearing, etc. that may be caused by stress concentration at one or some connection parts of the bracket assembly 40.

[0156] refer to Figure 2 , Figure 8 In some embodiments, the support member base 22 includes a fifth portion 221 connected to the support member body 21 and a sixth portion 222 connected to the fifth portion 221, and the sixth portion 222 is bent relative to the fifth portion 221 and connected to the longitudinal beam 10; the support member base 22 also includes a reinforcing rib 223, and the reinforcing rib 223 is connected to the fifth portion 221 and the sixth portion 222.

[0158] The sixth part 222 refers to a partial structure of the support base 22. The sixth part 222 is used to connect to the longitudinal beam 10. The sixth part 222 can be fixedly connected to the longitudinal beam 10 by welding, bonding or other methods, and can also be detachably connected to the longitudinal beam 10 by screwing, riveting or other methods; the shape of the sixth part 222 can be plate-like, block-like or other shapes, the shape of the sixth part 222 can be square, circular or other shapes; the sixth part 222 can be integrally formed with the fifth part 221, and can also be fixedly connected to the fifth part 221 by welding, bonding or other methods.

[0159] The sixth portion 222 is bent relative to the fifth portion 221 and is provided with a reinforcing rib 223 , so that the reinforcing rib 223 can be connected to the fifth portion 221 and the sixth portion 222 , thereby improving the strength of the support base 22 .

[0160] The reinforcing rib 223 refers to a partial structure of the support base 22, and the reinforcing rib 223 is used to improve the strength of the support base 22; the reinforcing rib 223 can be a plate-like structure, or a block-like structure or a structure of other shapes, and the reinforcing rib 223 can be a triangle, or a trapezoid or other shapes; the number of the reinforcing ribs 223 can be one, or two or more; the reinforcing ribs 223 can be connected to the fifth part 221 and the sixth part 222 by welding, bonding or other means; the material of the reinforcing rib 223 can include metal, plastic or other materials, and the material of the reinforcing rib 223 can be the same as or different from the material of the fifth part 221 and the sixth part 222.

[0161] Since the support member body 21 is used to provide a fixed foundation for the shock-absorbing structure of the vehicle 1000, the support member body 21 is easily subjected to a large force; accordingly, in this embodiment, reinforcing ribs 223 are provided on the support member base 22 to further improve the stability of the connection between the support member 20 and the longitudinal beam 10, and to improve the strength of the support member base 22; and since the bracket assembly 40 is connected to the support member base 22, this arrangement also enables the support member base 22 to better provide support for the bracket assembly 40.

[0162] refer to Figure 2 , Figure 8 In some embodiments, the bracket assembly 40 is connected to the reinforcing rib 223 .

[0163] The bracket assembly 40 can be fixedly connected to the reinforcing rib 223 by welding, bonding, etc., or can be detachably connected to the reinforcing rib 223 by screwing, clamping or other methods; the bracket assembly 40 can be connected to only one reinforcing rib 223, or can be connected to two or more reinforcing ribs 223.

[0164] For example, the connection seat 43 of the bracket assembly 40 is connected to the reinforcing rib 223 by bolts. In the case where there are multiple reinforcing ribs 223, the connection seat 43 is connected to one reinforcing rib 223.

[0165] In this embodiment, the bracket assembly 40 is arranged on the reinforcing rib 223 so that the support base 22 can better provide support for the bracket assembly 40; at the same time, compared with arranging the bracket assembly 40 on the support base 22, arranging the bracket assembly 40 on the reinforcing rib 223 can also reduce the interference of the connecting seat 43 on the overall strength of the support 20.

[0166] refer to Figure 2 , Figure 3 In some embodiments, the support member 20 is a tower base, which is used for installing a shock absorbing structure.

[0167] The tower seat refers to a structure on the frame 100 that is mainly used to support part of the suspension system of the vehicle 1000. The springs, shock absorbers or other structures of the suspension system can be arranged on the tower seat to buffer and absorb the energy of wheel vibration; at least part of the tower seat can extend above the wheel to facilitate the installation of structures such as springs and shock absorbers.

[0168] In the front structure of the vehicle frame 100 , there are usually two towers; for example, when there are two longitudinal beams 10 and two towers, the two towers are connected to the two longitudinal beams 10 respectively.
