[0001] This application relates to the field of new energy commercial vehicle technology, and in particular to a side-mounted power battery frame and vehicle. Background Technology

[0002] With the development of new energy technologies, the demand for power battery capacity in commercial vehicles continues to grow. Due to the large size and weight of large-capacity batteries, side-mounted power battery frames are typically used to arrange the battery pack laterally on both sides of the vehicle frame in order to lower the vehicle's center of gravity and improve driving stability.

The side plates of the two battery frames are bolted to the vehicle frame, and then the battery pack is placed inside the battery frame to complete the installation of the battery pack on the vehicle.

[0004] However, when it is necessary to maintain the battery pack and remove the aforementioned side-mounted power battery frame from the vehicle frame, the operation is inconvenient and affects maintenance efficiency. Utility Model Content

[0011] Two connecting parts are spaced apart and arranged on the same side of the support. Both connecting parts are connected to the support. The two connecting parts are located on both sides of the width direction of the frame. The connecting parts are arranged opposite to the frame for connection with the frame.

[0012] The bending part and the connecting part are connected one-to-one, and the bending part is located on the side of the connecting part away from the frame.

[0013] In one possible implementation, the side-mounted power battery frame provided in this application has a bending portion including two sub-bending portions, which are located at opposite ends of the connecting portion, and the sub-bending portions include a first bending segment and a second bending segment.

[0014] One end of the first bend is connected to the end of the corresponding connector, and the other end extends in a direction away from the connector. The second bend is connected to the other end of the first bend so that the second bend is away from the frame. The frame member is connected to the second bend on the same side.

[0015] In one possible implementation, the side-mounted power battery frame provided in this application includes two sequentially arranged support sections, with each support section corresponding to a connecting section.

[0016] One of the two support sections is configured to drive the corresponding connecting part to slide relative to the other to adjust the gap between the two connecting parts; wherein the gap is used to match the width of the frame.

[0017] In one possible implementation, the side-mounted power battery frame provided in this application further includes at least two reinforcing parts in the connector, with each connector corresponding to at least one reinforcing part, and the reinforcing part connecting one end of the corresponding connector and the support part.

[0018] In one possible implementation, the side-mounted power battery frame provided in this application also includes multiple fasteners, with a corresponding number of fasteners on the same frame component, and the frame component is detachably connected to a portion of the bent portion located on the same side through a portion of the fasteners.

[0019] In one possible implementation, the side-mounted power battery frame provided in this application uses screws as fasteners. The frame component has multiple first threaded holes, and a portion of the bent section has multiple first through holes. The first threaded holes and first through holes correspond one-to-one, and the screws pass through the first through holes and connect to the first threaded holes; or...

[0020] The fasteners are bolts and nuts. The frame has multiple second through holes and multiple third through holes in some bent parts. The second through holes and the third through holes correspond one-to-one. The bolts pass through the second through holes and the third through holes in sequence and are fitted with nuts.

[0021] In one possible implementation, the side-mounted power battery frame provided in this application has one connector, which is located in the middle of the vehicle frame, or...

[0022] There are two or more connectors, and each connector is used to be spaced apart along the length of the frame.

[0026] The side-mounted power battery frame and vehicle provided in this application are configured with at least one connector and two frame members, the connector having two bends. When mounting the two battery packs of the vehicle onto the frame, the connector is first connected to the vehicle frame, with the two bends located on opposite sides of the frame's width direction, extending in directions away from each other, so that portions of the two bends are partially located away from the frame. Then, by corresponding the frame members to the vehicle's battery packs one-to-one, with the interior of the frame members accommodating the corresponding battery packs, the two frame members are positioned on opposite sides of the frame's width direction, and the frame members are connected to portions of the bends located on the same side. This allows the frame members and the battery packs they support to be independently detached from the connector during disassembly. Furthermore, the design of the bends being partially away from the frame allows the disassembly path to avoid internal wiring harnesses and other components, reducing spatial interference and improving maintenance convenience and operational efficiency.

[0038] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions in the embodiments of this application will be described in more detail below with reference to the accompanying drawings. In the drawings, the same or similar reference numerals denote the same or similar components or components having the same or similar functions throughout.

All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application. The embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0039] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, an indirect connection through an intermediate medium, or the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0040] In the description of this application, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0041] The terms "first," "second," "third," "fourth," etc., used in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented, for example, in a sequence other than those illustrated or described herein.

[0042] Furthermore, the terms “comprising” and “having”, and any variations thereof, are intended to cover non-exclusive inclusion, such that a process, method, system, product, or apparatus that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or apparatus.

[0043] With the development of new energy technologies, the demand for power battery capacity in commercial vehicles continues to grow. Due to the large size and weight of large-capacity batteries, side-mounted power battery frames are typically used to arrange the battery pack laterally on both sides of the vehicle frame in order to lower the vehicle's center of gravity and improve driving stability.

[0044] In the prior art, the side-mounted power battery frame is an integral support frame structure. The side-mounted power battery frame has two battery frames, left and right. The side plates of the two battery frames are bolted to the vehicle frame, and then the battery pack is placed inside the battery frame to complete the installation of the battery pack on the vehicle.

[0045] When battery pack maintenance is required, the battery pack is completely enclosed within a frame, with its sides and bottom restricted by the frame structure. Furthermore, there are usually cushioning pads or auxiliary fixing devices between the battery pack and the frame, making it impossible to pull the battery pack directly upwards or laterally within the limited space of the vehicle. Therefore, to safely and completely remove the battery pack, the entire power battery frame must first be removed from the vehicle frame and moved to an open area such as a repair platform before disassembling and maintaining the battery pack.

[0046] However, after the vehicle is assembled, the frame typically houses components such as wiring harnesses and motors. The direct fixing structure between the battery pack and the frame makes it easy for maintenance personnel to interfere with these components when removing bolts. Therefore, when it is necessary to maintain the battery pack and remove the aforementioned side-mounted power battery frame from the frame, the operation is inconvenient and affects maintenance efficiency.

[0047] In view of this, this application provides a side-mounted power battery frame and a vehicle. The side-mounted power battery frame is provided with at least one connector and two frame members, and the connector has two bends. When installing the two battery packs of the vehicle onto the frame, the connector is first connected to the vehicle frame, so that the two bends are located on both sides of the width direction of the frame, and the two bends extend in opposite directions, so that the partial structures of the two bends are set away from the frame. Then, by corresponding the frame members with the battery packs of the vehicle one by one, the interior of the frame members is used to accommodate the corresponding battery packs, and the two frame members are respectively set on both sides of the width direction of the frame, and the frame members are connected to the partial structures of the bends located on the same side. In this way, the frame members and the battery packs they carry can be independently detached from the connector when disassembling, and because the partial structures of the bends are designed to be away from the frame, the disassembly path can avoid components such as pipelines and harnesses inside the frame, which helps to reduce spatial interference and improve maintenance convenience and work efficiency.

[0048] The present application will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0049] See Figures 1 to 4 The side-mounted power battery frame 100 provided in this application embodiment includes two frame members 102 and at least one connector 101. The connector 101 is used to connect to the vehicle frame 300. The connector 101 has two bends 110, which are located on both sides of the width direction of the frame 300 and extend in a direction away from each other, so that part of the structure of the two bends 110 is disposed away from the frame 300. The frame members 102 are used to correspond one-to-one with the battery packs 200 of the vehicle. The interior of the frame members 102 is used to accommodate the corresponding battery packs 200. The two frame members 102 are located on both sides of the width direction of the frame 300, and the frame members 102 are connected to part of the structure of the bends 110 located on the same side.

[0050] It should be noted that the side-mounted power battery frame 100 of this application embodiment is applicable to various electric vehicles with power battery installation requirements that adopt a side-mounted layout. For example, it can be applied to heavy-duty trucks, medium and heavy-duty freight vehicles driven by pure electric or hybrid power; or, it can be applied to large passenger vehicles such as urban buses and intercity long-distance electric buses; of course, it can also be applied to electric sanitation vehicles, electric dump trucks, electric tractor units, and large logistics delivery vehicles, etc. This application embodiment does not limit this.

[0051] It should also be noted that, such as Figure 4 As shown in the description of the embodiments of this application, the length direction of the frame 300 can be the Y direction, the width direction of the frame 300 can be referenced to the X direction, and the height direction can be referenced to the Z direction; wherein, X, Y, and Z are mutually perpendicular coordinate systems.

[0052] Among them, the connector 101 serves as a transitional connection structure between the vehicle and the battery system. Its main body is used to fix it to the vehicle frame 300. For example, it can be reliably fastened by bolts or rivets to ensure structural stability and safety during the load-bearing process.

[0053] For example, the connector 101 can be symmetrical in structure, and has two bent portions 110 arranged opposite to each other along the width direction of the frame 300. The bent portions 110 can be formed by stamping or bending processes and have a certain extension length and structural strength.

[0054] The two bends 110 are located on the left and right sides of the frame 300, respectively, that is, on both sides of the width direction of the frame 300. The bends 110 can extend outward toward the frame 300 to form an outwardly offset cantilever structure, so that part of the structure of the bends 110 is away from the frame 300. In this way, the connection area between the bends 110 and the frame member 102 is offset from the mounting plane of the frame 300, leaving an operating clearance for the assembly of the frame member 102, thereby avoiding the passage of high-voltage wiring harnesses, cooling pipes, drive shafts or drive motors and other peripheral components already arranged inside the frame 300.

[0055] The frame member 102 is a structural unit that directly supports the battery pack 200. Each frame member 102 is connected to one battery pack 200, providing mechanical support and positioning for the battery pack 200. Two frame members 102 are respectively set on both sides of the width direction of the frame 300 and connected to the left and right battery packs 200 one by one.

[0056] The frame component 102 can be a box-shaped structure welded from metal profiles, possessing good torsional stiffness and load-bearing capacity. The frame component 102 has a receiving cavity for accommodating the corresponding battery pack. The inner side of the frame component 102 can also be provided with positioning pins, limiting blocks, and buffer pads for mounting the battery pack 200, to adapt to the external dimensions of the battery pack 200 and provide vibration damping protection.

[0057] In the prior art, the battery frame, as a single structure, is directly connected to the vehicle frame 300 via bolt holes on its side plate. These bolt holes are located on the side of the battery frame closer to the centerline of the vehicle frame 300, i.e., the inner connection surface. When the battery pack 200 is installed into the battery frame, the side wall of its metal casing completely covers this inner connection area, forcing the connecting bolts to be inserted from the obscured location. Tools cannot access this area, making it impossible to secure the battery frame to the vehicle even after the battery pack 200 is installed in the battery frame.

[0058] During mass production of vehicles, the chassis is typically located in a fixed position on the assembly line, where space is limited, and other assemblies such as the suspension system, transmission components, and electrical wiring harnesses are gradually integrated around it. In this environment, precisely aligning and securing the empty battery frames to both sides of the frame 300 using multiple bolts requires high assembly precision and stability, making the process cumbersome and time-consuming. Especially when the battery frames are large and heavy, the lack of a battery pack 200 as a counterweight or auxiliary positioning structure makes lifting and positioning the empty frames even more difficult, prone to swaying or shifting, affecting connection reliability.

[0059] Therefore, in order to facilitate assembly, the frame component 102 and the battery pack 200 can be assembled as one unit in this embodiment. That is, the battery pack 200 is installed in the internal bearing area of ​​the frame component 102, and its connection structure, such as limiting block, buffer pad, locking point, etc., is mainly distributed on the bottom surface, inner wall or front and rear end face of the frame component 102, so as not to occupy the connection area of ​​the outer end of the frame component 102.

[0060] Furthermore, through the outwardly extending bend 110, the connection point between the frame member 102 and the bend 110 is located on the outer side of the frame 300 in the width direction, in the open space area on the side of the vehicle. Then, each frame member 102 is fixedly connected to the bend 110 on the same side by a detachable connection method, for example, by using bolts to lock the connection between the mounting lugs on the frame member 102 and the mating holes on the bend 110. The overall assembly process is as follows. Figure 2 , Figure 3 and Figure 4 As shown.

[0061] Here, because the bend 110 extends outward and deviates from the main body of the frame 300, the frame member 102 and the battery pack 200 connected to it are suspended in the outer area of ​​the frame 300, away from the dense pipelines and mechanical components in the middle of the frame 300. This arrangement optimizes the weight distribution of the vehicle, lowers the center of gravity, and provides ample operating space for subsequent disassembly operations.

[0062] Specifically, when maintenance is required on the battery pack 200, maintenance personnel can first disconnect the electrical and hydraulic interfaces of the battery pack 200. Then, they only need to remove the fasteners between the connecting frame 102 and the bent portion 110 to separate the entire frame 102 along with the battery pack 200 from the vehicle. Since the connection point is located on the outside of the frame 300 and avoids obstacles inside the frame 300, the problem of repeated adjustments and interference caused by the inner bolts being blocked can be avoided.

[0063] Understandably, connector 101 can remain on the frame 300 without repeated disassembly and reassembly, further simplifying the maintenance process.

[0064] In summary, the side-mounted power battery frame 100 provided in this application embodiment, when mounting two battery packs 200 of a vehicle onto the frame 300, first connects the connector 101 to the vehicle frame 300, so that the two bent portions 110 are located on both sides of the width direction of the frame 300, and the two bent portions 110 extend in a direction away from each other, so that part of the structure of the two bent portions 110 is set away from the frame 300; then, by corresponding the frame member 102 with the battery pack 200 of the vehicle one by one, the interior of the frame member 102 is used to accommodate the corresponding battery pack 200, and the two frame members 102 are respectively set on both sides of the width direction of the frame 300, and the frame member 102 is connected to part of the structure of the bent portion 110 located on the same side. This allows the frame 102 and the battery pack 200 it carries to be independently detached from the connector 101 during disassembly. Furthermore, because the structure of the bent portion 110 is located away from the frame 300, the disassembly path can avoid components such as pipelines inside the frame 300, which helps to reduce spatial interference and improve maintenance convenience and work efficiency.

[0065] See Figure 1 and Figure 4 In some examples, connector 101 includes a support portion 120 and two connecting portions 130. The support portion 120 extends along the width direction of the frame 300. The two connecting portions 130 are spaced apart on the same side of the support portion 120 and are connected to the support portion 120. The two connecting portions 130 are located on opposite sides of the frame 300 in the width direction and are arranged opposite to the frame 300 for connection. A bending portion 110 is connected to the connecting portions 130 one by one and is located on the side of the connecting portion 130 away from the frame 300.

[0066] Thus, modular design helps to improve the assembly stability and load-bearing capacity between connector 101 and frame 300.

[0067] The support portion 120, as the main load-bearing component of the connector 101, extends along the width of the vehicle to match the lateral spacing of the frame 300, ensuring balanced force on both sides. Two connector portions 130 are respectively located on the same side of the support portion 120 and spaced apart along its length. The distance between them matches the width of a local structure of the frame 300, allowing a portion of the frame 300 to be embedded between the two connector portions 130, forming a stable clamping connection.

[0068] The bending portion 110 is connected to the connecting portion 130 one by one, and each bending portion 110 is located on the side of the connecting portion 130 away from the frame 300, that is, extending towards the outside of the vehicle, so as to ensure that the connection point of the frame member 102 is moved outward and away from the frame 300 and the densely arranged pipelines and mechanical parts around it.

[0069] For example, the connecting part 130 and the supporting part 120 are fixedly connected, for example by welding or integral molding, as long as the connection between the two is reliable, and the embodiments of this application do not limit this.

[0070] See Figure 1 and Figure 2 In some embodiments, the bending portion 110 includes two sub-bending portions 111, which are located at opposite ends of the connecting portion 130. Each sub-bending portion 111 includes a first bending segment 1111 and a second bending segment 1112. One end of the first bending segment 1111 is connected to the end of the corresponding connecting portion 130, and the other end extends in a direction away from the connecting portion 130. The second bending segment 1112 is connected to the other end of the first bending segment 1111, so that the second bending segment 1112 is away from the frame 300. The frame member 102 is connected to the second bending segment 1112 on the same side.

[0071] This allows the second bending section 1112 to be located in an open space outside the side edge of the frame 300, avoiding the high-voltage wiring harness, cooling pipes, drive shaft and other auxiliary components arranged inside the frame 300, which facilitates assembly and maintenance operations.

[0072] One end of the first bending section 1111 is fixedly connected to the end of the connecting part 130. This connection can be achieved by welding, riveting or bolting to ensure structural strength and reliability. The sub-bending part 111 can be an L-shaped plate structure, that is, the other end of the first bending section 1111 is connected to the second bending section 1112, and the two form a 90° angle. The plane of the second bending section 1112 can be set opposite to the frame member 102 for easy assembly. The sub-bending part 111 can be made of metal sheet by bending or stamping process, and has good extension length and structural rigidity.

[0073] For example, by providing two sub-bends 111, the two sub-bends 111 are symmetrically distributed at opposite ends of the connecting part 130 along the length direction of the frame 300, so as to enhance the stability and load uniformity of the connecting structure.

[0074] In a specific example, the support 120 includes two support segments (not shown in the figure) arranged in sequence, and the support segments are connected to the connecting segments 130 in a one-to-one correspondence; one of the two support segments is configured to drive the corresponding connecting segment 130 to slide relative to the other to adjust the distance between the two connecting segments 130; wherein the distance is used to match the width of the frame 300.

[0075] This allows the side-mounted power battery frame 100 to be adapted to the installation requirements of different vehicle models or different specifications of the frame 300, thus improving its versatility.

[0076] For example, the sliding structure can be achieved by setting a guide mechanism between the two support sections, such as using a slide rail and a slide groove, a guide rod and a sleeve, or by using a long strip adjustment hole and a fastener to achieve relative displacement.

[0077] When connector 101 is installed onto the frame 300, maintenance personnel can adjust the distance between the two connecting parts 130 according to the actual local structural width of the frame 300 to ensure precise matching with the mounting areas on both sides of the frame 300. After adjustment, the relative positions of the two support sections are fixed by locking mechanisms such as nuts, pins, or clamping bolts to prevent loosening or displacement during use, ensuring that connector 101 has sufficient structural reliability when supporting the battery pack 200.

[0078] Continue reading Figure 1 In some examples, the connector 101 further includes at least two reinforcing portions 140, with the same connecting portion 130 corresponding to at least one reinforcing portion 140, and the reinforcing portion 140 connecting one end of the corresponding connecting portion 130 and the support portion 120.

[0079] Thus, the reinforcing part 140 serves as an auxiliary load-bearing structure. By connecting one end of the reinforcing part 140 to one end of the connecting part 130 and the other end to the supporting part 120, an oblique support is formed, thereby enhancing the bending resistance of the connecting part 130 in the direction perpendicular to the plane of the frame 300.

[0080] Specifically, when the connector 101 is fastened to the frame 300 through the connecting part 130, the connecting part 130 will be subjected to a combined downward and outward load from the bending part 110 and the frame member 102. The presence of the reinforcing part 140 can effectively transfer this load to the supporting part 120, and then distribute it evenly to the entire connector 101 structure, thereby improving the overall load-bearing stability.

[0081] The reinforcing part 140 can be plate-shaped or rib-shaped, made of metal, and fixedly connected to the connecting part 130 and the supporting part 120 by welding, riveting, or integral molding. The reinforcing member is inclinedly arranged in the angled area between the connecting part 130 and the supporting part 120, forming a triangular or near-triangular support configuration, thereby effectively dispersing the bending moment and shear force generated by the connecting part 130 when bearing the load of the battery pack 200, and preventing structural deformation or fatigue cracking caused by stress concentration.

[0082] In a specific implementation, the number of reinforcing parts 140 can be set to four, that is, two reinforcing parts 140 correspond to the same connecting part 130, and each connecting part 130 has a reinforcing part 140 at both ends, so as to achieve more uniform force distribution and multi-point reinforcement.

[0083] In some examples, the side-mounted power battery frame 100 also includes multiple fasteners, with a number of fasteners corresponding to the same frame member 102, and the frame member 102 is detachably connected to a portion of the bent portion 110 located on the same side via a number of fasteners.

[0084] The frame member 102 is detachably connected to a portion of the bent portion 110 via a number of fasteners, that is, the frame member 102 is connected to the second bent section 1112 located on the same side via a number of fasteners.

[0085] In this way, by setting multiple fasteners, a reliable connection between the frame component 102 and the bending part 110 is achieved, which also facilitates subsequent maintenance and replacement operations and meets the operational requirements during assembly and maintenance.

[0086] For example, when maintenance is required on one side of the battery pack 200, only a number of fasteners corresponding to that side of the frame 102 need to be removed to separate the frame 102 and the battery pack 200 from the vehicle frame 300 as a whole, while the fasteners and their connecting structures on the other side can remain in place without disassembly, effectively reducing the complexity of maintenance.

[0087] Continue reading Figures 1 to 3 In a specific example, the fastener is a screw 103, the frame member 102 has a plurality of first threaded holes 1021, and the partially bent part 110 has a plurality of first through holes 1112a. The first threaded holes 1021 and the first through holes 1112a correspond one-to-one. The screw 103 passes through the first through hole 1112a and connects to the first threaded hole 1021.

[0088] Thus, the engagement between the screw 103 and the first threaded hole 1021 has high connection rigidity and vibration resistance, which can effectively transfer the load of the battery pack 200 to the bending part 110, and then transmit it to the frame 300 through the connector 101, ensuring the structural stability of the entire power battery frame during vehicle operation.

[0089] Furthermore, by opening multiple first threaded holes 1021 on the frame member 102, the multiple first threaded holes 1021 can be evenly distributed in the connection area of ​​the frame member 102, such as the mounting ear plate at the outer end, to ensure balanced force distribution.

[0090] For example, the partial bend 110, i.e. Figure 2 Two first through holes 1112a are respectively provided on the two second bend segments 1112 of the bend portion 110 shown in the figure, and the two first through holes 1112a are spaced apart along the height direction of the frame 300. Accordingly, it is possible to... Figure 3Four first threaded holes 1021 are opened at corresponding positions on the frame component 102. At the same time, there are four screws 103 corresponding to the frame component 102. By sequentially operating the four screws 103 to pass through the corresponding first through holes 1112a and connect to the first threaded holes 1021, the assembly of the frame component 102 and the connector 101 can be completed.

[0091] In other examples, the fasteners are bolts and nuts (not shown in the figure), the frame member 102 has multiple second through holes, and the partially bent portion 110 has multiple third through holes. The second through holes and the third through holes correspond one-to-one. The bolt passes through the second through holes and the third through holes in sequence and is fitted with a nut.

[0092] Thus, the bolt, as a fastening element, passes through the second through hole on the frame member 102 and the third through hole on the bent portion 110 in sequence, with its shank penetrating the overlapping area of ​​the two parts. Then, a nut is fitted onto the end and locked in place, forming a stable clamping connection.

[0093] Overall, the bolt body bears shear force, and the threaded connection part bears tensile force, which can effectively resist multi-directional loads caused by vibration, bumps or turning during vehicle operation.

[0094] In practical implementation, since the bolts and nuts are separate components, the assembly is highly flexible and can be applied to the combination of bending parts 110 and frame parts 102 of different thicknesses. Simultaneously, washers can be placed at the connection interface to further disperse compressive stress, prevent deformation or wear of the material around the second and third through holes, and extend the service life of the structure.

[0095] In some embodiments, the number of connectors 101 is one, and the connector 101 is disposed in the middle of the frame 300.

[0096] Thus, by setting the number of connectors 101 to one and placing them in the middle of the frame 300, the high-rigidity area of ​​the frame 300 structure can be effectively utilized to improve the overall load-bearing stability, while reducing the number of parts, assembly complexity and manufacturing costs.

[0097] Understandably, the dimensions of connector 101 along the length of the frame 300 can be adapted to the length of the battery pack 200. Overall, the design of connector 101 is suitable for vehicle models with a moderate total length of battery pack 200 and concentrated load distribution, resulting in a compact structure that is beneficial for lightweight vehicle design.

[0098] Alternatively, in a specific implementation, there may be two or more connectors 101, with each connector 101 spaced apart along the length of the frame 300.

[0099] In this way, by forming a multi-point support structure through two or more connectors 101, the concentrated load of the battery pack 200 can be distributed and transferred to multiple local areas of the frame 300, effectively reducing local stress concentration and improving the structural bending and torsional resistance; at the same time, it is beneficial to improve the connection stiffness between the frame member 102 and the frame 300, and enhance the operational safety of the battery pack 200.

[0100] For example, the number and position of the connectors 101 can be flexibly adjusted according to the frame structure 300 and battery layout requirements of different vehicle models, which is suitable for the installation requirements of large-capacity and long-size power batteries.

[0101] like Figure 2 As shown, there can be three connectors 101. Each connector 101 can be installed sequentially and equidistantly in the front, middle, and rear areas of the frame 300. Each connector 101 has a bent portion 110 for connecting to the frame member 102. The frame member 102 is connected one by one to the second bent section 1112 of each connector 101 on the same side by fasteners, thereby achieving multi-point fixation along the length of the battery pack 200.

[0102] This application also provides a vehicle, including a vehicle body and a side-mounted power battery frame 100 disposed on the vehicle body as in any of the above embodiments.

[0103] The specific structure and operation of the side-mounted power battery frame 100 have been described in detail in the above embodiments, and will not be repeated here.

[0104] In some embodiments, the vehicle body includes a frame 300 and two battery packs 200, the two battery packs 200 being located on both sides of the frame 300 in the width direction; the connector 101 of the side-mounted power battery frame 100 is connected to the frame 300, the frame member 102 of the side-mounted power battery frame 100 corresponds one-to-one with the battery pack 200, and the interior of the frame member 102 accommodates the corresponding battery pack 200.

[0105] The vehicle provided in this application embodiment features a side-mounted power battery frame 100. This frame 100 includes at least one connector 101 and two frame members 102. The connector 101 has two bends 110. When mounting the two battery packs 200 onto the vehicle frame 300, the connector 101 is first connected to the vehicle frame 300, with the two bends 110 located on opposite sides of the width direction of the frame 300. The two bends 110 extend in directions away from each other, ensuring that a portion of the structure of each bend 110 is located away from the frame 300. Then, the frame members 102 are matched one-to-one with the battery packs 200 of the vehicle body, with each frame member 102 accommodating a corresponding battery pack 200. The two frame members 102 are positioned on opposite sides of the width direction of the frame 300, and a portion of the structure of the bend 110 on the same side is connected to the frame member 102.

[0106] This allows the frame 102 and the battery pack 200 it carries to be independently detached from the connector 101 during disassembly. Furthermore, because the structure of the bent portion 110 is located away from the frame 300, the disassembly path can avoid components such as pipelines inside the frame 300, which helps to reduce spatial interference and improve maintenance convenience and work efficiency.

[0107] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
