[0003] The present application relates to the technical field of new energy vehicles, and in particular to a bracket, a bracket assembly, and a vehicle. Background Art

[0004] New energy vehicles have become an important part of the sustainable development of the vehicle industry due to their energy-saving and environmentally friendly advantages. With the development of new energy vehicles, people's requirements for the cruising range of new energy vehicles are also increasing. In order to meet the needs of new energy vehicles to replenish power loss in time during driving, solutions such as battery replacement and timely replenishment of power loss have emerged.

[0005] For new energy vehicles, how to improve the degree of lightweighting is a technical problem that needs to be solved urgently.

[0006] Summary of the Invention

[0007] The present application provides a bracket, a bracket assembly and a vehicle. The technical solution provided in the present application can improve the lightweight degree of the vehicle.

[0008] This application is achieved through the following technical solutions:

[0009] In a first aspect, the present application provides a bracket for mounting on a vehicle frame, the bracket comprising a mounting beam. The mounting beam is provided with a plurality of mounting portions, the plurality of mounting portions being spaced apart along the length of the mounting beam, the plurality of mounting portions being configured to detachably connect a battery. The mounting beam has a cavity formed therein, the cavity extending along the length of the mounting beam.

[0010] In the above solution, the bracket is mounted on the vehicle frame, and the mounting portion on the mounting beam is detachably connected to the battery. By arranging multiple mounting portions at intervals along the length of the mounting beam, it is possible to achieve subcontracted battery replacement (i.e., on-demand battery replacement. For example, when the required battery life is shorter, a smaller number of batteries can be installed on the corresponding number of mounting portions in the multiple mounting portions; when the required battery life is longer, a larger number of batteries can be installed on the corresponding number of mounting portions in the multiple mounting portions) and / or increase the number of locking points between the mounting beam and the battery to improve the locking strength. Among them, by providing a cavity within the mounting beam, on the one hand, the bracket can be lightweight, thereby improving the lightweight degree of the vehicle; on the other hand, because the extension direction of the cavity is consistent with the arrangement direction of the multiple mounting portions, the impact of the cavity on the rigidity and strength of the bracket can be effectively reduced. Compared with a solution in which the cavity is arranged along an oblique or perpendicular direction to the length of the mounting beam, the risk of the bracket being bent or even broken by impact along the portion where the mounting portion is located can be reduced, thereby ensuring that the bracket has higher reliability while being more lightweight.

[0011] According to some embodiments of the present application, the mounting portion includes a mounting hole formed on the mounting beam; the mounting hole passes through the mounting beam along a first direction, and the first direction is perpendicular to the length direction of the mounting beam.

[0012] In the above scheme, on the one hand, the mounting part has a simple structure and is easy to manufacture; on the other hand, because the mounting part has a simple structure, the connection method between the battery and the mounting part is also simple, which can effectively improve the battery replacement efficiency; on the other hand, the extension direction of the cavity and the penetration direction of the mounting hole are perpendicular to each other, which can effectively reduce the influence of the cavity on the stiffness and strength of the bracket, so that the bracket has a higher structural strength to stably mount the battery, thereby improving the driving reliability of the vehicle.

[0013] According to some embodiments of the present application, the mounting portion further includes a mounting sleeve, and at least a portion of the mounting sleeve is disposed in the mounting hole.

[0014] In the above solution, by providing a mounting sleeve in the mounting hole, the structural strength of the mounting portion can be improved, so that the battery can be stably connected to the bracket, reducing the risk of battery falling off and improving the driving reliability of the vehicle.

[0015] According to some embodiments of the present application, along the first direction, the mounting beam has a first end wall and a second end wall opposite to each other, and the mounting sleeve is connected to the first end wall and the second end wall.

[0016] In the above solution, by setting the mounting sleeve to be connected to the first end wall and the second end wall, the mounting sleeve and the mounting beam are made as a whole, which can effectively improve the problem of reduced strength of the bracket structure due to the setting of the cavity, improve the rigidity and strength of the mounting part, improve the deformation resistance of the bracket when mounting the battery, reduce the risk of battery falling off, and thus improve the driving reliability of the vehicle.

[0017] According to some embodiments of the present application, the outer contour of the cross section of the mounting beam is rectangular.

[0018] In the above solution, by setting the outer contour of the cross section of the mounting beam to a rectangle, the mounting beam has good strength and rigidity after being provided with the cavity, thereby improving the anti-deformation ability of the bracket when mounting the battery.

[0019] According to some embodiments of the present application, a support member is provided in the cavity, and the support member is connected to the mounting beam.

[0020] In the above solution, by arranging the support member in the cavity, the strength and rigidity of the mounting beam can be effectively improved, the anti-deformation ability of the bracket can be improved, and the driving reliability of the vehicle can be improved.

[0021] According to some embodiments of the present application, the support member and the mounting beam are integrally formed.

[0022] In the above solution, the support member and the mounting beam are integrally formed, which can make the bracket have higher strength and rigidity, improve the bracket's ability to resist deformation when mounting the battery, reduce the risk of battery falling off, and thus improve the vehicle's driving reliability.

[0023] According to some embodiments of the present application, the support member and the mounting beam are formed by bending a single plate.

[0024] In the above solution, the support member and the mounting beam are formed by bending a single plate, so that the bracket has higher manufacturing efficiency and lower manufacturing cost.

[0025] According to some embodiments of the present application, the support member divides the cavity into a plurality of sub-cavities, and the sub-cavities extend along the length direction of the mounting beam.

[0026] In the above scheme, the cavity is divided into multiple sub-cavities by the support member, and each sub-cavity is independent of each other. While increasing the lightweight degree of the bracket, it can effectively improve the strength and rigidity of the mounting beam, improve the deformation resistance of the bracket, reduce the risk of battery detachment, and thus improve the driving reliability of the vehicle.

[0027] According to some embodiments of the present application, the plurality of sub-cavities include a first sub-cavity and a second sub-cavity. The mounting beam includes a first wall, a second wall, a third wall, a fourth wall, a fifth wall and a sixth wall. Along the second direction, the two ends of the first wall are respectively connected to one end of the second wall and one end of the third wall; along the first direction, the fourth wall is spaced apart from the first wall, and one end of the fourth wall is connected to the other end of the second wall; along the first direction, the fifth wall is spaced apart from the first wall, and one end of the fifth wall is connected to the other end of the third wall; along the first direction, one end of the sixth wall is connected to the other end of the fourth wall, and the other end of the sixth wall is connected to the first wall, and the first wall, the second wall, the fourth wall and the sixth wall together form a first sub-cavity; the other end of the fifth wall is connected to the sixth wall, and the first wall, the third wall, the fifth wall and the sixth wall together form a second sub-cavity, and the first direction, the second direction and the length direction of the mounting beam are perpendicular to each other.

[0028] In the above solution, the mounting beam has a simple structure and is easy to manufacture. The support member may include a sixth wall. By providing the sixth wall so as to connect the fourth wall and the first wall of the mounting beam, the strength and rigidity of the mounting beam can be effectively improved, the risk of battery detachment can be reduced, the deformation resistance of the bracket can be improved, and the driving reliability of the vehicle can be improved.

[0029] According to some embodiments of the present application, a first bending portion is provided at an end of the sixth wall away from the fourth wall, and the first bending portion extends along the second direction and is connected to the first wall.

[0030] In the above scheme, by setting the first bending portion, the connection area between the sixth wall and the first wall can be increased, the supporting capacity of the sixth wall can be improved, the strength and rigidity of the mounting beam can be effectively improved, the deformation resistance of the bracket can be improved, the risk of battery falling off can be reduced, and the driving reliability of the vehicle can be improved.

[0031] According to some embodiments of the present application, the first bent portion extends from the end of the sixth wall toward the third wall.

[0032] The above solution, by setting the first bent portion to extend toward the third wall, can make the bracket evenly bear the impact, improve the bracket's anti-deformation ability, reduce the risk of battery falling off, and thus improve the driving reliability of the vehicle.

[0033] According to some embodiments of the present application, a second bending portion is provided at an end of the fifth wall away from the third wall, and the second bending portion extends along the first direction and is connected to the sixth wall.

[0034] In the above scheme, by setting the second bending portion, the connection area between the fifth wall and the sixth wall can be increased, and the connection reliability between the fifth wall and the sixth wall can be improved, so that the geometric shape of the cross section of the mounting beam has good load-bearing capacity, and the bracket has good anti-deformation ability while reducing the structural mass.

[0035] According to some embodiments of the present application, the bracket further includes a connecting portion, which is connected to the mounting beam and is used to be connected to the longitudinal beam of the frame.

[0036] In the above solution, by providing a connecting portion, the mounting beam can be effectively connected to the longitudinal beam of the frame, so that the mounting beam can effectively carry the battery through the mounting portion, reducing the risk of battery falling off and improving the driving reliability of the vehicle.

[0037] According to some embodiments of the present application, two connecting parts are provided on the mounting beam, and the two connecting parts are arranged at intervals. The two connecting parts and the mounting beam together form an upwardly open groove, and the groove is used for the frame to pass through.

[0038] In the above scheme, by providing two connecting parts, on the one hand, a groove that avoids the longitudinal beam of the frame can be formed; on the other hand, the connecting part can be connected to the outer side surface of the corresponding longitudinal beam, that is, the two longitudinal beams of the frame are respectively connected by the corresponding connecting parts, so that there is a stable connection relationship between the mounting unit and the frame, reducing the risk of battery falling off and improving the reliability of vehicle driving; on the other hand, since two connecting parts are provided and the two connecting parts are arranged at intervals along the lateral direction of the frame, that is, the mounting beam can be provided with more mounting parts to mount larger batteries or more batteries, thereby effectively improving the vehicle's endurance.

[0039] According to some embodiments of the present application, the bracket further includes a rib plate, which is located on a side of the connecting portion away from the groove, and the rib plate connects the mounting beam and the connecting portion.

[0043] According to some embodiments of the present application, a notch is formed at one end of the rib plate close to the mounting beam, and the notch is arranged corresponding to the mounting portion.

[0044] In the above solution, a notch is provided at one end of the rib plate close to the mounting beam to free up space above the mounting portion, thereby reducing the risk of interference by the rib plate when the battery is mounted on the mounting portion.

[0045] According to some embodiments of the present application, the connecting portion is a flange provided on the rib plate, and the rib plate and the connecting portion are provided perpendicular to each other.

[0048] In the above scheme, the rib plate can be a double-layer plate structure. Since the rib plate is a double-layer plate structure, the rib plate can form two flanges facing opposite directions, that is, forming a first sub-connection part and a second sub-connection part, so that there is a larger connection area between the rib plate and the longitudinal beam, thereby improving the connection reliability between the rib plate and the longitudinal beam, thereby improving the structural strength of the mounting beam, allowing the mounting beam to effectively carry the battery and reduce the risk of the battery falling off.

[0049] According to some embodiments of the present application, the bracket includes a plurality of mounting beams, and the plurality of mounting beams are arranged at intervals, and at least a partial accommodating space for accommodating the battery is formed between two adjacent mounting beams.

[0050] In the above solution, the bracket includes multiple mounting beams, so that at least a partial accommodating space for accommodating the battery can be formed between two adjacent mounting beams, so that the batteries can be installed in the corresponding accommodating space in an orderly manner, thereby improving the battery replacement efficiency of the vehicle.

[0053] According to some embodiments of the present application, the longitudinal beam includes a web, an upper wing plate, and a lower wing plate, wherein the web connects the upper wing plate and the lower wing plate. The bracket further includes a connecting portion connected to the web.

[0054] In the above solution, the bracket is connected to the web of the longitudinal beam via the connecting portion, so that the bracket can be effectively installed on the longitudinal beam, reducing the risk of the bracket falling off the longitudinal beam and improving the reliability of vehicle driving.

[0055] According to some embodiments of the present application, the mounting beam is connected to the lower wing panel.

[0056] In the above solution, the bracket is connected to the web of the longitudinal beam through the connecting portion and to the lower wing plate of the longitudinal beam through the mounting beam, so that the bracket can be firmly installed on the longitudinal beam, reducing the risk of the bracket falling off the longitudinal beam and improving the reliability of vehicle driving.

[0057] According to some embodiments of the present application, the bracket assembly further includes a reinforcement member connected to the longitudinal beam and the connecting portion.

DETAILED DESCRIPTION

[0081] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0082] Unless otherwise defined, all technical and scientific terms used in this application have the same meanings as commonly understood by those skilled in the art to which this application belongs. The terms used in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application. The terms "including" and "having" and any variations thereof in the specification and claims of this application and the above-mentioned drawings are intended to cover non-exclusive inclusions. The terms "first" and "second" in the specification and claims of this application or the above-mentioned drawings are used to distinguish different objects, rather than to describe a specific order or a primary-secondary relationship.

[0083] References to "embodiments" in this application mean that a particular feature, structure, or characteristic described in connection with the embodiment may be included in at least one embodiment of the application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described in this application may be combined with other embodiments.

[0084] In the description of this application, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," "connected," and "attached" should be understood in a broad sense. For example, they may refer to fixed connections, detachable connections, or integral connections; they may refer to direct connections, indirect connections through an intermediate medium, or internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on specific circumstances.

[0085] The term "and / or" in this application simply describes an association between related objects, indicating that three possible relationships exist. For example, A and / or B can represent: A exists alone, A and B exist simultaneously, and B exists alone. In addition, the character " / " in this application generally indicates that the related objects are in an "or" relationship.

[0086] The term "multiple" in this application refers to more than two (including two). Similarly, "multiple groups" refers to more than two groups (including two groups), and "multiple pieces" refers to more than two pieces (including two pieces).

[0087] In some embodiments, the battery may be a battery module. When there are multiple battery cells, the multiple battery cells are arranged and fixed to form a battery module.

[0088] In some embodiments, the battery may be a battery pack, which includes a case and battery cells, wherein the battery cells or battery modules are housed in the case.

[0089] In some embodiments, the battery cells may be secondary batteries, which are batteries that can be recharged to activate their active materials after discharge and continue to be used. The battery cells may be lithium-ion batteries, sodium-ion batteries, sodium-lithium-ion batteries, lithium metal batteries, sodium metal batteries, lithium-sulfur batteries, magnesium-ion batteries, nickel-metal hydride batteries, nickel-cadmium batteries, lead-acid batteries, and the like, although this disclosure is not intended to limit this.

[0090] At present, new energy vehicles often use battery replacement to timely replenish the power loss of new energy vehicles during driving.

[0091] For new energy vehicles, lightweighting affects the manufacturing cost and cruising range of new energy vehicles. Therefore, how to reduce lightweighting is a technical problem that needs to be solved urgently.

[0092] New energy vehicles with battery swapping capabilities often have a battery swap bracket mounted on their frames. The bracket's mounting beam is equipped with a mounting portion for removably connecting to the battery. The mounting portion includes a mounting hole, typically a through-hole extending through two opposing walls of the beam. Currently, to minimize the impact of the mounting hole on the beam's strength and rigidity, the beam is often constructed of a solid structure, resulting in increased weight and impacting the vehicle's lightweighting.

[0093] In light of this, and to enhance vehicle lightweighting, some embodiments of the present application provide a bracket for mounting on a vehicle frame. The bracket includes a mounting beam. The mounting beam is provided with multiple mounting portions, spaced apart along the lengthwise direction y of the mounting beam, and configured to detachably connect a battery. The mounting beam has a cavity formed therein, extending along the lengthwise direction of the mounting beam.

[0094] In the above solution, the bracket is used to be mounted on the vehicle frame, and the mounting portion on the mounting beam is used to be detachably connected to the battery. By arranging multiple mounting portions at intervals along the length direction y of the mounting beam, it is possible to achieve subcontracted battery replacement (that is, battery replacement on demand. For example, when the required battery life is shorter, a smaller number of batteries can be installed on the corresponding number of mounting portions in the multiple groups of mounting portions; when the required battery life is longer, a larger number of batteries can be installed on the corresponding number of mounting portions in the multiple groups of mounting portions) and / or increase the number of locking points between the mounting beam and the battery to improve the locking strength. Among them, by setting a cavity inside the mounting beam, on the one hand, the bracket can be made lighter, thereby improving the degree of lightweighting of the vehicle; on the other hand, because the extension direction of the cavity is consistent with the arrangement direction of the multiple mounting parts, the influence of the setting of the cavity on the stiffness and strength of the bracket can be effectively reduced. Compared with the solution in which the cavity is set along the length direction inclined or perpendicular to the mounting beam, the risk of the bracket being bent or even broken along the location of the mounting part due to impact can be reduced, so that the bracket has higher reliability under the condition of higher degree of lightweight.

[0095] The bracket disclosed in the embodiments of the present application can be installed on, but not limited to, the frame of a passenger vehicle, the frame of a commercial freight vehicle, and other vehicle frames. The vehicle disclosed in the embodiments of the present application can be used in, but not limited to, passenger vehicles, commercial freight vehicles, and other vehicles.

The mounting portions 110 are configured to detachably connect to the battery 200. A cavity 111 is formed within the mounting beam 11, extending along the longitudinal direction y of the mounting beam.

[0102] In some embodiments, the vehicle frame 50 may be a frame-like structure spanning the front and rear axles of the vehicle, commonly known as a beam, and serves as the vehicle's foundation. The functions of the vehicle frame 50 may include supporting and connecting the various vehicle assemblies, ensuring they maintain relative correct positioning, and bearing various internal and external vehicle loads. In some embodiments, the vehicle frame 50 is located at the bottom of the vehicle.

[0103] In some embodiments, the bracket 10 is a component fixed to the vehicle frame 50. In some embodiments, the bracket 10 can be connected to the vehicle frame 50 by bonding, welding, riveting, screwing, etc. In other embodiments, the bracket 10 can be integrally formed with the vehicle frame 50. In some embodiments, the bracket 10 can be connected to the longitudinal beam 51 of the vehicle frame 50.

[0104] In some embodiments, the bracket 10 has a certain structural strength to be able to mount the battery 200. In some embodiments, the material of the bracket 10 can be the same as that of the frame 50. In some embodiments, the material of the bracket 10 can be aluminum alloy, steel, cast iron, or reinforced plastic.

[0105] The mounting beam 11 is a beam structure, which may be in the shape of a rod, a stick, a plate or a cylinder, etc. The mounting beam 11 may be a strip-shaped structure. The length direction y of the mounting beam may be the direction in which the size of the mounting beam 11 is larger. Referring to FIG2 , the length direction y of the mounting beam may be perpendicular to the longitudinal direction of the longitudinal beam 51 (the length direction of the longitudinal beam 51). In some embodiments, as shown in FIG2 , a portion of the mounting beam 11 may be located between a pair of longitudinal beams 51 of the frame 50, and a portion of the mounting beam 11 may be on both sides of the frame 50 along the transverse direction of the frame 50. In other embodiments, the mounting beam 11 may be located on the outside of the frame 50. In other embodiments, the mounting beam 11 may be located between a pair of longitudinal beams 51 of the frame 50.

[0106] In some embodiments, the bracket 10 may include a plurality of mounting beams 11. The plurality of mounting beams 11 may be spaced apart, for example, spaced apart from each other along a direction perpendicular to the longitudinal direction y of the mounting beams. In some embodiments, the plurality of mounting beams 11 may be connected to each other via connecting members, for example, two adjacent mounting beams 11 may be connected by connecting rods.

[0107] The mounting portion 110 is used for detachable connection with the battery 200. When the bracket 10 is applied to a vehicle, the detachable connection between the mounting portion 110 and the battery 200 enables battery replacement in the vehicle.

[0108] There are multiple mounting portions 110. On one mounting beam 11, multiple mounting portions 110 are spaced apart along the longitudinal direction y of the mounting beam.

[0109] In some embodiments, multiple mounting portions 110 on a mounting beam 11 can be used to connect to the same battery 200. In some embodiments, multiple mounting portions 110 on a mounting beam 11 can be used to connect to different batteries 200. For example, some mounting portions 110 on a mounting beam 11 can be used to connect to the same battery 200, while other portions can be used to connect to different batteries 200. In some embodiments, one mounting beam 11 can carry one battery 200 or multiple batteries 200. In some embodiments, multiple mounting beams 11 can collectively carry one battery 200 or multiple batteries 200.

[0110] In some embodiments, the mounting portion 110 includes but is not limited to a mounting hole, a mounting screw, and other structures that can achieve a detachable connection with the battery 200 .

[0111] The phrase "a cavity 111 is formed within the mounting beam 11" can be understood as meaning that the cavity 111 is formed within the mounting beam 11, thereby reducing the weight of the mounting beam 11. In some embodiments, the cavity 111 may refer to a hollow portion within the mounting beam 11. The cavity 111 may or may not extend through the wall of the mounting beam 11. For example, in some embodiments, the cavity 111 extends through both ends of the mounting beam 11 along the length direction y of the mounting beam. In another example, in some embodiments, the cavity 111 is a chamber structure within the mounting beam 11 that is not connected to the outside world.

[0112] “The cavity 111 extends along the length direction y of the mounting beam” can be understood as the direction of the maximum dimension of the cavity 111 is the length direction y of the mounting beam, that is, it can be understood as the cavity 111 extends along the arrangement direction of the multiple mounting parts 110 .

[0113] In the above solution, the bracket 10 is used to be installed on the vehicle frame 50, and the mounting portion 110 on the mounting beam 11 is used to be detachably connected to the battery 200. By arranging multiple mounting portions 110 at intervals in the length direction y of the mounting beam, it is possible to achieve subcontracted battery replacement (that is, battery replacement on demand, for example, when the required battery life is shorter, a smaller number of batteries 200 can be installed on the corresponding number of mounting portions 110 in the multiple groups of mounting portions 110; when the required battery life is longer, a larger number of batteries 200 can be installed on the corresponding number of mounting portions 110 in the multiple groups of mounting portions 110) and / or increase the locking points between the mounting beam 11 and the battery 200 to improve the locking strength. Among them, by providing a cavity 111 inside the mounting beam 11, on the one hand, the bracket 10 can be made lightweight, thereby improving the lightweight degree of the vehicle; on the other hand, because the cavity 111 is provided to extend along the length direction y of the mounting beam, the impact on the rigidity and strength of the bracket 10 can be effectively reduced. Compared with the solution in which the cavity 111 is provided along an inclined or perpendicular direction y of the mounting beam, the risk of the bracket 10 being impacted and bent or even broken along the portion where the mounting portion 110 is located can be reduced, so that the bracket 10 has higher reliability under the condition of a higher degree of lightweight.

[0114] According to some embodiments of the present application, please refer to Figure 4, which is an enlarged view of point A in Figure 2. The mounting portion 110 includes a mounting hole 1100 formed on the mounting beam 11. The mounting hole 1100 penetrates the mounting beam 11 along a first direction z, which is perpendicular to the longitudinal direction y of the mounting beam.

[0115] Mounting hole 1100 may be a through-hole extending through mounting beam 11 along a first direction z. First direction z is perpendicular to the length of mounting beam 11. In some embodiments, when bracket 10 is used in a vehicle, first direction z may be the direction of gravity. In some embodiments, battery 200 may include a mounting member that passes through mounting hole 1100 and is mounted on mounting beam 11.

[0116] In some embodiments, mounting hole 1100 extends through mounting beam 11 along a first direction z, and cavity 111 extends through mounting beam 11 along its length direction y. In some embodiments, mounting hole 1100 and cavity 111 may communicate with each other within mounting beam 11. In some embodiments, when bracket 10 is used in a vehicle, because mounting hole 1100 and cavity 111 both extend through mounting beam 11 and communicate with each other within mounting beam 11, water that enters bracket 10 from outside can be quickly drained from mounting beam 11.

[0117] In the above scheme, on the one hand, the mounting part 110 has a simple structure and is easy to manufacture; on the other hand, due to the simple structure of the mounting part 110, the connection method between the battery 200 and the mounting part 110 is also simple, which can effectively improve the battery replacement efficiency; on the other hand, the extension direction of the cavity 111 and the penetration direction of the mounting hole 1100 are perpendicular to each other, which can effectively reduce the influence of the cavity 111 on the stiffness and strength of the bracket 10, so that the bracket 10 has a higher structural strength to stably mount the battery 200, thereby improving the driving reliability of the vehicle.

[0118] According to some embodiments of the present application, please refer to Figure 5, which is a schematic diagram of the mounting hole 1100 and the mounting sleeve 1101 in some embodiments of the present application.

[0119] The mounting portion 110 further includes a mounting sleeve 1101 , at least a portion of which is disposed in the mounting hole 1100 .

[0120] In some embodiments, the mounting sleeve 1101 can be disposed within the mounting hole 1100. The mounting sleeve 1101 can be disposed within the mounting hole 1100 by bonding, welding, screwing, or other methods. In some embodiments, the material of the mounting sleeve 1101 can be the same as or different from the material of the mounting beam 11. In some embodiments, the material of the mounting sleeve 1101 can be aluminum alloy, steel, or reinforced plastic.

[0121] In the above solution, by providing the mounting sleeve 1101 in the mounting hole 1100 , the structural strength of the mounting portion 110 can be improved, so that the battery 200 can be stably connected to the bracket 10 , reducing the risk of the battery 200 falling off and improving the driving reliability of the vehicle.

[0122] According to some embodiments of the present application, referring to FIG. 5 , along a first direction z, the mounting beam 11 has a first end wall 112 and a second end wall 113 opposite to each other, the mounting sleeve 1101 exceeds the first end wall 112 and the second end wall 113 , and the mounting sleeve 1101 is connected to the first end wall 112 and the second end wall 113 .

[0123] The first end wall 112 and the second end wall 113 are two opposite walls of the mounting beam 11 in the first direction z. In some embodiments, the first direction z may be the direction of gravity, the first end wall 112 may be the top wall of the mounting beam 11, and the second end wall 113 may be the bottom wall of the mounting beam 11.

[0124] "The mounting sleeve 1101 is connected to the first end wall 112 and the second end wall 113" can be understood as that both ends of the mounting sleeve 1101 in the first direction z can be connected to the first end wall 112 and the second end wall 113. The connection relationship between the mounting sleeve 1101 and the first end wall 112, and the mounting sleeve 1101 and the second end wall 113 includes, but is not limited to, welding, bonding, screwing, riveting, etc.

[0125] In some embodiments, in the first direction z, the dimensions of the mounting beam 11 may exceed the dimensions of the mounting beam 11, such that either end of the mounting beam 11 extends beyond the first end wall 112 and the second end wall 113. For example, in the first direction z, both ends of the mounting beam 11 extend beyond the first end wall 112 and the second end wall 113, the portion of the mounting beam 11 extending beyond the first end wall 112 being connected to the first end wall 112, and the portion of the mounting beam 11 extending beyond the second end wall 113 being connected to the second end wall 113.

[0126] For example, referring to FIG5 , the portion of the mounting beam 11 extending beyond the first end wall 112 may be formed with a flange, which may be connected to the outer surface of the first end wall 112. The connection between the flange and the first end wall 112 includes, but is not limited to, overlapping, welding, bonding, riveting, or screw connection. The other end of the mounting beam 11 may be connected to the second end wall 113. The mounting beam 11 may be connected to the inner or outer surface of the second end wall 113. The connection between the mounting beam 11 and the second end wall 113 includes, but is not limited to, overlapping, welding, bonding, riveting, or screw connection. When the bracket 10 is applied to a vehicle, the second end wall 113 and the first end wall 112 are spaced apart from each other due to the provision of the cavity 111. When the mounting beam 11 is mounted with a battery 200, the weight of the battery 200 can be shared between the first end wall 112 and the second end wall 113 through the transmission of the mounting sleeve 1101, thereby improving the deformation resistance of the mounting beam 11.

[0127] In some embodiments, the portion of the mounting beam 11 extending beyond the second end wall 113 may be formed with a flange, which may be connected to the outer surface of the second end wall 113. The connection between the flange and the second end wall 113 includes, but is not limited to, lap joint, welding, bonding, riveting, or screw connection.

[0128] In the above scheme, by setting the mounting sleeve 1101 to be connected to the first end wall 112 and the second end wall 113, the mounting sleeve 1101 and the mounting beam 11 are made as a whole, which can effectively improve the problem of reduced structural strength of the bracket 10 due to the setting of the cavity 111, improve the rigidity and strength of the mounting part 110, improve the deformation resistance of the bracket 10 when mounting the battery 200, reduce the risk of the battery 200 falling off, and thereby improve the driving reliability of the vehicle.

[0129] According to some embodiments of the present application, please refer to Figure 2. The outer contour of the cross section of the mounting beam 11 is rectangular.

[0130] The cross section of the mounting beam 11 can be understood as a plane obtained by cutting the mounting beam 11 along a plane perpendicular to the longitudinal direction y of the mounting beam. The rectangular outer contour of the cross section of the mounting beam 11 can be understood as the outer contour of the cross section of the mounting beam 11 can be rectangular or similar.

[0131] In some embodiments, the mounting beam 11 has a hollow interior in its cross section, and the hollowness is formed by the cavity 111 .

[0132] In the above solution, by setting the outer contour of the cross section of the mounting beam 11 to a rectangle, the mounting beam 11 has good strength and rigidity after being provided with the cavity 111 , thereby improving the anti-deformation ability of the bracket 10 when mounting the battery 200 .

[0133] In other embodiments, the cross section of the mounting beam 11 may be a triangle, a pentagon, or other shapes.

[0134] According to other embodiments of the present application, please refer to FIG. 6 , which is a schematic diagram of a cross section of the mounting beam 11 in other embodiments of the present application.

[0135] A support member 1110 is disposed in the cavity 111 , and the support member 1110 is connected to the mounting beam 11 .

[0136] The support member 1110 is disposed within the cavity 111, and both ends of the support member 1110 can be connected to the inner wall of the mounting beam 11. In some embodiments, the support member 1110 can be a rod-shaped member or a rod-like member, and its opposite ends can be connected to different inner walls of the mounting beam 11 (for example, the opposite ends of the support member 1110 can be connected to opposite inner walls of the mounting beam 11).

[0137] In some embodiments, the material of the mounting sleeve 1101 may be the same as or different from the material of the mounting beam 11. In some embodiments, the material of the mounting sleeve 1101 may be aluminum alloy, steel, or reinforced plastic.

[0138] In some embodiments, the support member 1110 may be a component of the mounting beam 11, for example, integrally formed with the mounting beam 11. In other embodiments, the support member 1110 is not a component of the mounting beam 11, and after the mounting beam 11 is provided with the cavity 111, the support member 1110 is then placed into the cavity 111.

[0139] In some embodiments, the thickness direction of the support member 1110 may be perpendicular to the first direction z.

[0140] In the above solution, by arranging the support member 1110 in the cavity 111 , the strength and rigidity of the mounting beam 11 can be effectively improved, the anti-deformation capability of the bracket 10 can be improved, and the driving reliability of the vehicle can be improved.

[0141] According to some embodiments of the present application, the support member 1110 and the mounting beam 11 are integrally formed.

[0142] In some embodiments, the support member 1110 and the mounting beam 11 can be integrally formed by casting or roll forming.

[0143] Roll forming is a process that relies on the plastic movement characteristics of materials and uses the principle of rolling extrusion to form various complex parts. For example, referring to Figure 6, the support member 1110 and the mounting beam 11 can be made by roll forming sheet metal parts.

[0144] In the above solution, the support member 1110 and the mounting beam 11 are integrally formed, which can make the bracket 10 have higher strength and rigidity, improve the anti-deformation ability of the bracket 10 when mounting the battery 200, reduce the risk of the battery 200 falling off, and thus improve the driving reliability of the vehicle.

[0145] According to some embodiments of the present application, the support member 1110 and the mounting beam 11 are formed by bending a single plate.

[0146] In some embodiments, the support member 1110 and the mounting beam 11 can be formed by bending a single plate through a roll forming process. In other embodiments, the support member 1110 and the mounting beam 11 can be formed by bending a single plate through a bending process.

[0147] Among them, the mounting beam 11 and the support member 1110 are made by a roll forming process, which has the following advantages: the shape of the cross section can be reasonably designed to improve the bearing capacity of the mounting beam 11 and make the mounting beam 11 lightweight; high-strength materials can be used to further make the mounting beam 11 lightweight while meeting the bearing requirements; and the manufacturing cost is low.

[0148] In the above solution, the support member 1110 and the mounting beam 11 are formed by bending a single plate, so that the bracket 10 has higher manufacturing efficiency and lower manufacturing cost.

[0149] According to some embodiments of the present application, the support member 1110 divides the cavity 111 into a plurality of sub-cavities 111 , and the sub-cavities 111 extend along the length direction y of the mounting beam.

[0150] The cavity 111 extends along the longitudinal direction y of the mounting beam. In some embodiments, the support member 1110 divides the cavity 111 into a plurality of sub-cavities 111 along a direction perpendicular to the longitudinal direction y of the mounting beam, so that the sub-cavities 111 extend along the longitudinal direction y of the mounting beam.

[0151] The length direction y perpendicular to the mounting beam may be a first direction z. The length direction y perpendicular to the mounting beam may also be a second direction x, and the second direction x may be perpendicular to the first direction z. In some embodiments, when the support member 1110 divides the cavity 111 into a plurality of sub-cavities 111 along the first direction z, the mounting hole 1100 may pass through the support member 1110. In some embodiments, when the support member 1110 divides the cavity 111 into a plurality of sub-cavities 111 along the first direction z, the mounting hole 1100 may not pass through the support member 1110.

[0152] In some embodiments, when the mounting hole 1100 passes through the support member 1110, the mounting sleeve 1101 can be connected to the support member 1110. The connection relationship between the mounting sleeve 1101 and the support member 1110 includes but is not limited to welding, bonding, screw connection, riveting, etc.

[0153] In the above scheme, the cavity 111 is divided into multiple sub-cavities 111 by the support member 1110, and each sub-cavity 111 is independent of each other. While increasing the lightweight degree of the bracket 10, it can effectively improve the strength and rigidity of the mounting beam 11, improve the deformation resistance of the bracket 10, reduce the risk of the battery 200 falling off, and thereby improve the driving reliability of the vehicle.

[0154] 6 , the plurality of sub-cavities 111 include a first sub-cavity 1111 and a second sub-cavity 1112 . The mounting beam 11 includes a first wall 21 , a second wall 22 , a third wall 23 , a fourth wall 24 , a fifth wall 25 , and a sixth wall 26 . Along the second direction x, the two ends of the first wall 21 are respectively connected to one end of the second wall 22 and one end of the third wall 23; along the first direction z, the fourth wall 24 is spaced apart from the first wall 21, and one end of the fourth wall 24 is connected to the other end of the second wall 22; along the first direction z, the fifth wall 25 is spaced apart from the first wall 21, and one end of the fifth wall 25 is connected to the other end of the third wall 23; along the first direction z, one end of the sixth wall 26 is connected to the other end of the fourth wall 24, and the other end of the sixth wall 26 is connected to the first wall 21, and the first wall 21, the second wall 22, the fourth wall 24 and the sixth wall 26 together form a first sub-cavity 1111; the other end of the fifth wall 25 is connected to the sixth wall 26, and the first wall 21, the third wall 23, the fifth wall 25 and the sixth wall 26 together form a second sub-cavity 1112, and the first direction z, the second direction x and the length direction y of the mounting beam are perpendicular to each other.

[0155] In some embodiments, the mounting portion 110 may be a mounting hole 1100, and the mounting hole 1100 may penetrate the mounting beam 11 along the first direction z. The second direction x may be perpendicular to the first direction z, and the second direction x may also be perpendicular to the length direction y of the mounting beam.

[0156] In some embodiments, the mounting beam 11 and support member 1110 can be formed by bending a plate-like structure. Referring to Figure 6 , the mounting beam 11 includes a first wall 21, a second wall 22, a third wall 23, a fourth wall 24, a fifth wall 25, and a sixth wall 26. The first wall 21 can be bent in the same direction along the first direction z at both ends in the second direction x to form the second wall 22 and the third wall 23, respectively. The second wall 22 can be bent in the second direction x toward the third wall 23 to form the fourth wall 24. The fourth wall 24 can be bent in the first direction z toward the first wall 21 to form the sixth wall 26. The third wall 23 can be bent in the second direction x toward the second wall 22 to form the fifth wall 25. The end of the fifth wall 25 away from the third wall 23 can be connected to the sixth wall 26.

[0157] The end of the sixth wall 26 away from the fourth wall 24 can be connected to the first wall 21 to provide support. The sixth wall 26 can be at least a part of the support member 1110, or it can be understood that the support member 1110 includes the sixth wall 26.

[0158] In some embodiments, the mounting hole 1100 may penetrate the first wall 21 and the fifth wall 25 , or the mounting hole 1100 may penetrate the first wall 21 and the fourth wall 24 .

[0159] Alternatively, in some other embodiments, different from the directions described above, the descriptions of the first wall 21, second wall 22, third wall 23, fourth wall 24, fifth wall 25, and sixth wall 26 with respect to the first direction z and the second direction x are swapped. For example, along the first direction z, the two ends of the first wall 21 are connected to one end of the second wall 22 and one end of the third wall 23, respectively. That is, the two ends of the first wall 21 in the first direction z can be bent toward the same direction along the first direction z to form the second wall 22 and the third wall 23, respectively. In these other embodiments, the mounting hole 1100 can pass through the third wall 23, the sixth wall 26, and the second wall 22.

[0160] In some embodiments, the connection between the sixth wall 26 and the first wall 21 includes, but is not limited to, abutment, bonding, welding, or screw connection. In some embodiments, the connection between the fifth wall 25 and the sixth wall 26 includes, but is not limited to, abutment, bonding, welding, or screw connection.

[0162] In the above solution, the mounting beam 11 has a simple structure and is easy to manufacture. The support member 1110 may include a sixth wall 26. By providing the sixth wall 26 so as to connect the fourth wall 24 and the first wall 21 of the mounting beam 11, the strength and rigidity of the mounting beam 11 can be effectively improved, the risk of battery 200 falling off can be reduced, the deformation resistance of the bracket 10 can be improved, and the driving reliability of the vehicle can be improved.

[0163] According to some embodiments of the present application, referring to FIG. 6 , a first bending portion 27 is provided at an end of the sixth wall 26 away from the fourth wall 24 . The first bending portion 27 extends along the second direction x and is connected to the first wall 21 .

[0164] The first bent portion 27 may be disposed at the end of the sixth wall 26 and extend along the second direction x to provide a larger connection area with the first wall 21. In some embodiments, the first bent portion 27 may extend toward the third wall 23. In other embodiments, the first bent portion 27 may extend toward the second wall 22.

[0165] In some embodiments, the connection relationship between the first bent portion 27 and the first wall 21 includes, but is not limited to, abutment, bonding, welding, or screw connection.

[0166] In the above solution, by setting the first bent portion 27 to extend toward the third wall 23, the bracket 10 can evenly bear the impact, improve the deformation resistance of the bracket 10, reduce the risk of the battery 200 falling off, and thus improve the driving reliability of the vehicle.

[0167] According to some embodiments of the present application, the first bent portion 27 extends from an end portion of the sixth wall 26 toward the third wall 23 .

[0168] In the above solution, by setting the first bent portion 27 to extend toward the third wall 23, the bracket 10 can evenly bear the impact, improve the deformation resistance of the bracket 10, reduce the risk of the battery 200 falling off, and thus improve the driving reliability of the vehicle.

[0169] According to some embodiments of the present application, a second bent portion 28 is provided at an end of the fifth wall 25 away from the third wall 23 . The second bent portion 28 extends along the first direction z and is connected to the sixth wall 26 .

[0171] In some embodiments, the connection relationship between the second bent portion 28 and the sixth wall 26 includes, but is not limited to, abutment, bonding, welding, or screw connection.

[0172] In the above scheme, by setting the second bending portion 28, the connection area between the fifth wall 25 and the sixth wall 26 can be increased, and the connection reliability between the fifth wall 25 and the sixth wall 26 can be improved, so that the geometric shape of the cross section of the mounting beam 11 has good load-bearing capacity, and the bracket 10 has good anti-deformation ability while reducing the structural mass.

[0173] In other embodiments of the present application, another mounting beam 11 is provided. Please refer to FIG. 7 , which is a schematic diagram of a cross-section of the mounting beam 11 in other embodiments of the present application.

[0190] According to some embodiments of the present application, referring to FIG8 , FIG8 is a schematic diagram of a partial structure of the bracket 10 in some embodiments of the present application. The rib 13 is provided with a bent portion 130 at one end near the mounting beam 11 , and the rib 13 is connected to the mounting beam 11 via the bent portion 130 .

[0191] The bent portion 130 is located at one end of the rib 13 near the mounting beam 11. The bent portion 130 may be formed by bending or rolling the rib 13. The bent portion 130 may be perpendicular to the main portion of the rib 13. The bent portion 130 has a surface facing the mounting beam 11, which is capable of connecting to a surface of the mounting beam 11.

[0192] In some embodiments, the rib 13 may be a double-layer plate structure, which may be composed of two stacked plate structures, one of which is bent to form a bent portion 130 connected to the mounting beam 11, and the other is bent to form a bent portion 130 connected to the mounting beam 11. The bent portions 130 of the two plate structures are bent in opposite directions, for example, along the thickness direction of the rib 13, toward both sides of the rib 13.

[0193] In the above solution, the bent portion 130 is provided at the end of the rib 13 close to the mounting beam 11 to increase the connection area between the rib 13 and the mounting beam 11 , thereby improving the connection reliability between the rib 13 and the mounting beam 11 .

[0194] According to some embodiments of the present application, a notch 131 is formed at one end of the rib 13 close to the mounting beam 11 , and the notch 131 is disposed corresponding to the mounting portion 110 .

[0195] The notch 131 can be a recessed structure (or a groove-like structure) formed at the end of the rib 13. The notch 131 is provided corresponding to the mounting portion 110 and can provide space above the mounting portion 110. In some embodiments, the battery 200 has a mounting member corresponding to the mounting hole 1100. The mounting member is inserted into the mounting hole 1100 to connect the battery 200 to the bracket 10. In the height direction, the height of the mounting member extending above the upper surface of the mounting beam 11 can be less than or equal to the distance from the bottom of the notch 131 to the upper surface of the mounting beam 11.

[0196] In the above solution, a notch 131 is provided at one end of the rib 13 close to the mounting beam 11 to free up space above the mounting portion 110 , thereby reducing the risk of interference by the rib 13 when the battery 200 is mounted on the mounting portion 110 .

[0197] According to some embodiments of the present application, referring to FIG. 3 , the connecting portion 12 is a flange provided on the rib 13 , and the rib 13 and the connecting portion 12 are provided perpendicular to each other.

[0198] The phrase "connecting portion 12 is a flanged edge provided on rib 13" can be understood as meaning that connecting portion 12 is formed by bending or rolling rib 13, i.e., connecting portion 12 and rib 13 are an integral structure. The phrase "rib 13 and connecting portion 12 are arranged perpendicular to each other" can be understood as meaning that connecting portion 12 is formed by bending rib 13 90 degrees.

[0199] In the above scheme, the connecting portion 12 can be a flange arranged on the rib 13, that is, the connecting portion 12 and the rib 13 are integrally formed, which can make the connecting portion 12 and the rib 13 have higher structural strength, and can effectively provide the structural strength of the mounting beam 11, thereby effectively carrying the battery 200 and reducing the risk of the battery 200 falling off.

[0200] According to some embodiments of the present application, the rib 13 includes a first rib 132 and a second rib 133 that are stacked, and the connecting portion 12 includes a first sub-connecting portion 12 and a second sub-connecting portion 12, the first sub-connecting portion 12 is a flange arranged on the first rib 132, and the second sub-connecting portion 12 is a flange arranged on the second rib 133.

[0201] In some embodiments, the rib 13 can be a double-layer plate structure. For example, the rib 13 can be formed by stacking two plate-like structures. For another example, the rib 13 can be formed by bending or other processes to form a two-layer plate structure from a single plate-like structure. Referring to FIG3 , in the thickness direction of the rib 13, the rib 13 has a first rib 132 and a second rib 133 stacked on top of each other. The first sub-connecting portion 12 is a flange formed by bending or rolling the first rib 132, and the second sub-connecting portion 12 is a flange formed by bending or rolling the second rib 133. In the thickness direction of the rib 13, the first sub-connecting portion 12 and the second sub-connecting portion 12 are located on opposite sides of the rib 13, respectively.

[0202] In the above scheme, the rib plate 13 can be a double-layer plate structure. Since the rib plate 13 is a double-layer plate structure, the rib plate 13 can form two flanges facing opposite directions, that is, forming a first sub-connection portion 12 and a second sub-connection portion 12, so that there is a larger connection area between the rib plate 13 and the longitudinal beam 51, thereby improving the connection reliability between the rib plate 13 and the longitudinal beam 51, thereby improving the structural strength of the mounting beam 11, so that the mounting beam 11 can effectively carry the battery 200 and reduce the risk of the battery 200 falling off.
