Detailed Implementation

[0036] 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. The described embodiments are some, but not all, embodiments of this application. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application. 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.

[0037] 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.

[0038] 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.

[0039] 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.

[0040] 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.

[0041] In related technologies, the chassis platform is generally formed by die casting of steel in one piece. Steel has a high density and is heavy, resulting in poor lightweighting of the chassis frame. This is especially true for new energy vehicles, which increases energy and range loss.

[0042] In addition, in new energy vehicles, battery packs are generally placed on both sides of the frame or in the middle above the frame and connected to the longitudinal beams by connecting brackets. However, there are many connecting parts between the battery pack and the connecting brackets, and the installation points of different battery packs are different, which means that the overall vehicle layout also needs to be adjusted accordingly, resulting in poor system integration and inconvenient assembly.

[0043] Based on the above description, one or more embodiments of this application provide a chassis platform and a vehicle. In the chassis platform, the power component is installed in the assembly housing. The front longitudinal beam, the power component, and the rear longitudinal beam are connected sequentially along the longitudinal beam direction of the vehicle. Thus, the power component is integrated on the chassis. The power component does not require additional connecting parts for fixation, but is directly fixed to the chassis through the assembly housing, eliminating the need for connecting brackets, simplifying the assembly structure of the power component and the chassis, saving the number of assembly parts, and effectively improving the assembly efficiency of the chassis.

[0044] The vehicle frame platform of this application embodiment will be described below with reference to the accompanying drawings.

[0045] like Figure 1 and Figure 2 As shown, the chassis platform includes a front longitudinal beam 100, a power unit, and a rear longitudinal beam 200. The power unit includes a mounting housing 300 and a power component disposed within the mounting housing 300. One side of the mounting housing 300 is connected to the front longitudinal beam 100. The rear longitudinal beam 200 is connected to the side of the mounting housing 300 away from the front longitudinal beam 100, so that the front longitudinal beam 100, the power unit, and the rear longitudinal beam 200 are sequentially connected along the longitudinal direction of the vehicle.

[0046] As can be seen from the above description, the vehicle frame platform of this application embodiment utilizes the assembly housing 300 and the front longitudinal beam 100 and the rear longitudinal beam 200 for connection, so that the front longitudinal beam 100, the assembly housing 300 and the rear longitudinal beam 200 form an integral connection structure. After the power component is installed in the assembly housing 300, it can be directly integrated on the vehicle frame without the need for additional connecting brackets, thereby reducing the number of connecting parts and facilitating the assembly of the power component.

[0047] In addition, the front longitudinal beam 100, the rear longitudinal beam 200 and the assembly shell 300 are connected in sections, making the frame platform modular. This allows for connections at different locations, enabling standardized assembly processes on the production line and improving production efficiency.

[0048] In the embodiments of this application, the vehicle can be a pure electric vehicle, a hybrid vehicle, or a natural gas vehicle. For different types of vehicles, the power components actually installed in the assembly housing 300 are also different. For example, in a pure electric vehicle, the power component is a battery; in a hybrid vehicle, the power component can be a battery and a generator. In this embodiment of the application, no absolute limitation is made.

[0049] The longitudinal beams of the vehicle extend along the longitudinal direction of the vehicle. The longitudinal beams mainly bear and distribute the transmission of forces from the road, collision or power system and other sources. Here, the longitudinal direction of the vehicle is the front-to-back direction of the vehicle, and the lateral direction of the vehicle is the left-to-right direction of the vehicle. In addition, in the embodiments of this application, the directional terms such as "inner side", "outer side", "upper", and "lower" are all described with reference to the orientation when the frame platform is assembled on the vehicle body, and will not be repeated below.

[0050] like Figure 2 As shown in the embodiment of this application, the frame platform also includes multiple connectors 400. The assembly housing 300 is connected to the front longitudinal beam 100 and the assembly housing 300 is connected to the rear longitudinal beam 200 through the connectors 400.

[0051] For example, such as Figure 2 and Figure 3 As shown, the aforementioned connector 400 includes a first limiting part 401 and a second limiting part 402. The first limiting part 401 abuts against the side wall of the front longitudinal beam 100 or the rear longitudinal beam 200 and is connected to the front longitudinal beam 100 or the rear longitudinal beam 200 by a fastener 405 that passes through it. The second limiting part 402 abuts against the side wall of the assembly housing 300 and is connected to the assembly housing 300 by a fastener 405 that passes through it.

[0052] Since the front longitudinal beam 100 and the assembly housing 300, and the rear longitudinal beam 200 and the assembly housing 300 are connected by connectors 400, each connector 400 can be a component with the same shape and structure. Here, the connector 400 between the front longitudinal beam 100 and the assembly housing 300 will be used as an example for explanation.

[0053] Specifically, the first limiting part 401 and the second limiting part 402 on the connector 400 between the front longitudinal beam 100 and the assembly housing 300 are both planar plates. The first limiting part 401 abuts against the side wall of the front longitudinal beam 100, and multiple fasteners 405 are provided on the first limiting part 401 and the side wall of the front longitudinal beam 100. The second limiting part 402 abuts against the side wall of the assembly housing 300, and multiple fasteners 405 are provided on the second limiting part 402 and the side wall of the assembly housing 300. The first limiting part 401 and the second limiting part 402 form the connection between the assembly housing 300 and the front longitudinal beam 100.

[0054] The fasteners 405 mentioned above can be bolts. Since the front longitudinal beam 100 and the assembly housing 300 have a certain height, the fasteners 405 can be set to be multiple and spaced apart according to the specifications and dimensions of the connector 400. For example, two rows of fasteners 405 are provided on the second limiting part 402, and each row of fasteners 405 has multiple fasteners 405. The multiple fasteners 405 are arranged along the height direction of the assembly housing 300. This arrangement can further improve the connection strength between the connector 400 and the assembly housing 300.

[0055] In some embodiments, the connector 400 further includes a transition portion 403, which connects the first limiting portion 401 and the second limiting portion 402, such that the second limiting portion 402 bends outward relative to the first limiting portion 401 in the lateral direction of the vehicle.

[0056] The cross-sections of the first limiting part 401, the transition part 403, and the second limiting part 402 are Z-shaped. The second limiting part 402 bends outward relative to the first limiting part 401 along the lateral direction of the vehicle, so that there is a certain width difference between the front longitudinal beam 100 and the mounting housing 300. As a result, the actual width of the mounting housing 300 is greater than the width of the two front longitudinal beams 100. The mounting housing 300 has a larger space and can be backward compatible with batteries of different sizes and specifications, thereby improving the versatility and adaptability of the mounting housing 300.

[0057] like Figure 3 As shown in the embodiment of this application, along the height direction of the vehicle, the upper and / or lower sides of the connector 400 are provided with a laterally bent baffle 404, which is configured to cover at least one of the front longitudinal beam 100, the rear longitudinal beam 200 and the mounting housing 300.

[0058] In the above embodiments, since the connector 400 is provided with a transition portion 403, the baffle 404 on the connector 400 is approximately triangular in shape. One side of the baffle 404 covers the edge of the assembly housing 300, and the other side covers the upper end face of the front longitudinal beam 100.

[0059] Specifically, baffles 404 are constructed on both the upper and lower sides of the connector 400. The connector 400 is fitted onto the front longitudinal beam 100 and the assembly housing 300 through the baffles 404 on the upper and lower sides. The baffles 404 can assist the first limiting part 401 and the second limiting part 402, thereby improving the limiting effect of the connector 400 on the front longitudinal beam 100 and the assembly housing 300.

[0060] As an alternative implementation, the first limiting part 401 is bonded to the side wall of the front longitudinal beam 100 or the rear longitudinal beam 200; and / or, the second limiting part 402 is bonded to the side wall of the assembly housing 300.

[0061] In the above embodiments, the first limiting part 401 and the front longitudinal beam 100, the first limiting part 401 and the rear longitudinal beam 200, the second limiting part 402 and the front longitudinal beam 100, and the second limiting part 402 and the rear longitudinal beam 200 are all connected by adhesive bonding. The adhesive shell adopts structural adhesives used in vehicle frame assembly technology, such as polyurethane adhesives and epoxy resin adhesives. The structural adhesive bonding and the fastener 405 connection of the connector 400 together ensure the connection effect between the power component and the front longitudinal beam 100 or the rear longitudinal beam 200.

[0062] like Figure 2 As shown in the embodiment of this application, there are two parallel longitudinal beams 100 in the front section and two parallel longitudinal beams 200 in the rear section. A supporting crossbeam 102 is provided between the two front longitudinal beams 100 and between the two rear longitudinal beams 200.

[0063] The spacing between the front longitudinal beams 100 is the same as the spacing between the rear longitudinal beams 200. The two front longitudinal beams 100 and the two rear longitudinal beams 200 are fixed by the support beams 102, so that the front longitudinal beams 100 and the rear longitudinal beams 200 form a stable rectangular frame structure, ensuring the overall rigidity of the frame.

[0064] Furthermore, the aforementioned support beam 102, connector 400, and front longitudinal beam 100 are connected by a common fastener 405, and the support beam 102, connector 400, and rear longitudinal beam 200 are connected by a common fastener 405.

[0065] Here, the ends of the two front longitudinal beams 100 are connected to the side ends of the assembly housing 300 through a connector 400, and the ends of the two rear longitudinal beams are connected to the other opposite side ends of the assembly housing 300 through a connector 400. Thus, the front longitudinal beams 100 and the rear longitudinal beams 200 are connected to the assembly housing 300 through a total of four connectors 400.

[0066] Specifically, such as Figure 1 and Figure 6 As shown, the cross-sections of the front longitudinal beam 100 and the rear longitudinal beam 200 are groove-shaped with openings 101. The openings 101 of the two front longitudinal beams 100 are arranged opposite each other, and the openings 101 of the two rear longitudinal beams 200 are also arranged opposite each other. The supporting crossbeam 102 includes a beam 1021 and clamping plates 1022 fixed to both ends of the beam 1021. The clamping plates 1022 are fitted into the openings 101 of the front longitudinal beam 100, and the groove-shaped openings 101 of the front longitudinal beam 100 limit its displacement in the height direction. Similarly, the supporting crossbeam located in the rear longitudinal beam 200 is fitted into the openings 101 of the rear longitudinal beam 200 through the clamping plates 1022, and the groove-shaped openings 101 of the rear longitudinal beam 200 limit its displacement in the height direction.

[0067] Furthermore, such as Figure 4 andFigure 5 As shown, the side end of the insertion opening 101 of the card plate 1022 is configured to be horizontally bent. The bent part of the card plate 1022 abuts against the upper side wall and the lower side wall of the opening 101 of the front longitudinal beam 100. The abutting part is also connected by a fastener 405 that passes through it. The fastener 405 can further improve the fixing effect of the card plate 1022 in the front longitudinal beam 100.

[0068] It should be noted that fastener 405 can be a bolt, and the actual fastening length of fastener 405 will vary for parts with different thicknesses.

[0069] Generally, multiple support beams 102 are provided on both the front longitudinal beam 100 and the rear longitudinal beam 200. Among them, the support beam 102 near the assembly housing 300 is connected to the connector 400.

[0070] like Figure 1 As shown, multiple fasteners 405 pass through the first limiting part 401 of the connector 400, the side wall of the front longitudinal beam 100, and the clamping plate 1022 of the supporting beam 102. The supporting beam 102, the connecting plate, and the front longitudinal beam 100 are all fixedly connected. Similarly, multiple fasteners 405 pass through the second limiting part 402 of the connector 400, the side wall of the rear longitudinal beam 200, and the clamping plate 1022 of the supporting beam 102. The supporting beam 102, the connecting plate, and the rear longitudinal beam 200 are all fixedly connected. Thus, the connection strength between the connector 400 and the front longitudinal beam 100 and the rear longitudinal beam 200 is further enhanced by the supporting beam 102.

[0071] It should be noted that in this embodiment, the connector 400 is a cast aluminum part, and at least one of the front longitudinal beam 100, the assembly housing 300, and the rear longitudinal beam 200 is an extruded aluminum part. Furthermore, the front longitudinal beam 100, the assembly housing 300, and the rear longitudinal beam 200 are all extruded aluminum parts. Extruded aluminum has lower mold costs and can be repeatedly recycled. The extruded aluminum shell can be reused homogeneously without heat treatment, thereby reducing carbon emissions and environmental pollution. The aluminum front longitudinal beam 100, rear longitudinal beam 200, and assembly housing 300 can also reduce the overall weight of the vehicle, contributing to its lightweight design.

[0072] like Figure 1 As shown, in some embodiments, multiple reinforcing ribs 301 are fixed at intervals on the outer periphery of the assembly housing 300. Since the assembly housing 300 itself is made of extruded aluminum, and the side wall of the assembly housing 300 is provided with a liquid cooling channel, coolant is circulated into the assembly housing 300 through the vehicle's water tank, which can reduce the temperature of the assembly housing 300, improve its heat dissipation performance, and ensure the normal operation of the battery.

[0073] The aforementioned liquid cooling channel can be located inside the side wall of the assembly housing 300 or at the bottom of the assembly housing 300. The shape of the liquid cooling channel can be flexibly arranged according to the size of the assembly housing 300. Generally, the assembly housing 300 is provided with an inlet and an outlet for the liquid cooling channel. The vehicle's water tank is connected to the inlet, and the vehicle's cooling equipment is connected to the outlet. Under pressure, the liquid enters the liquid cooling channel through the inlet and then enters the cooling equipment through the outlet for cooling, circulating to cool the assembly housing 300. Here, the structural design of the liquid cooling channel is only an example, and the embodiments of this application are not absolutely limited.

[0074] Furthermore, in some embodiments, a partition is provided inside the assembly housing 300, dividing the assembly housing 300 into two installation spaces. Different power components can be installed in the different installation spaces. For example, a battery cell assembly can be fixed in one installation space of the assembly housing 300, while a generator can be arranged in the other installation space. The partition improves the space utilization of the assembly housing 300. Of course, after the power components are installed, a corresponding cover should be provided to the assembly housing 300 to form a closed housing.

[0075] In this embodiment, the inner and outer surfaces of the assembly housing 300 are also coated with a protective coating. For example, the protective coating is a polyurea coating, an epoxy resin coating, a polyurethane coating, or a fluoropolymer coating. The protective coating can further improve the impact resistance and corrosion resistance of the assembly housing 300 and enhance the safety of the power components.

[0076] Another embodiment of this application provides a vehicle including a vehicle body and a chassis platform as described in any of the above embodiments disposed on the vehicle body. Since the vehicle includes a chassis platform as described in any of the above embodiments, it has all the advantages of a chassis platform.
