In addition, the separately arranged part of the structure is reduced, which reduces the overall weight of the CTP battery pack 5 to a certain extent and improves the integration of the slide chassis.

[0018]

[0019] ​In some optional embodiments, the first chamber 3 can also be structurally optimized. For example, some weight-reducing holes can be provided on the upper side beam, the lower side beam, the cross beam, the first longitudinal beam and the second longitudinal beam, or a new lightweight material can be used to manufacture the partition beam, so as to reduce the overall weight of the skateboard chassis 2 without affecting the structural strength and function, thereby helping to improve the energy efficiency and cruising range of the vehicle. In addition, a material can also be attached to the inner surface of the first chamber 3, such as a rust-proof coating, which can prevent the metal parts inside the chamber from rusting and corroding due to moisture or other reasons, thereby prolonging the service life of the skateboard chassis 2.

[0020] The CTP (Cell To Pack) battery pack 5 included in the skateboard chassis 2 has a battery pack 5 body arranged parallel to the first chamber 3, which facilitates installation, and the parallel arrangement to the first chamber 3 can make the outer wall of the CTP battery pack 5 perpendicular to the upper and lower side beams of the skateboard chassis 2, forming a regular shape, which facilitates the formation of a regular and sufficient space CTC battery compartment 6. Of course, the specific arrangement position of the CTP battery pack 5 body and the shape and size of the CTP battery pack 5 body can also be adaptively adjusted according to the overall design of the skateboard chassis 2, and the embodiments of the present application do not make specific limitations.

[0023] The upper beam is connected with the body side beam 1 through the second fastener 9 to realize the coupling connection of the body side beam 1 structure and the skateboard chassis 2, and the second fastener 9 can be a bolt, a connecting pin or other suitable connecting components, and the specific type and material of the second fastener 9 are not limited in the embodiment of the utility model, as long as the stable connection between the body side beam 1 and the upper beam of the skateboard chassis 2 can be realized to ensure the stability of the connection during the operation of the vehicle. At the same time, the cross-sectional shape and size of the connecting part of the body side beam 1 and the specific installation position of the second fastener 9 can be adjusted according to the design requirements of different vehicle models, and the embodiment of the utility model is not limited in this regard. The different specific installation positions of the second fastener 9 do not affect the realization of the basic function of the embodiment of the utility model.

[0024] In the embodiment of the utility model, the CTP battery pack 5 is arranged in the skateboard chassis 2, and the CTC battery compartment 6 is formed by the upper beam and the lower beam of the skateboard chassis 2 and the side wall of the CTP battery pack 5, which is compatible with the CTP battery pack 5 and the CTC battery compartment 6, allows different vehicle battery packs 5 or cell integration schemes to be selected according to different needs on the same skateboard chassis 2, increases the flexibility of the skateboard chassis 2 in terms of battery selection, and thus enhances the versatility of the skateboard chassis 2.

[0025] As an optional embodiment, as shown in Figure 1 The assembly positions of the first fastener 4 and the second fastener 9 are located in the same plane.

[0026] In the embodiment, the first fastener 4 is used to connect the bottom extension part of the CTC battery pack 5 and the crossbeam of the skateboard chassis 2, and the second fastener 9 is used to connect the body side beam 1 and the skateboard chassis 2. The assembly positions of the two are located in the same plane, which can make the connection force more uniform, and at the same time, it is convenient for standardized assembly operation in the production process. The fasteners are positioned and installed in the same plane, which can utilize unified tool clamps and assembly processes to reduce assembly difficulty and error, thereby improving the connection accuracy of the body side beam 1 and the skateboard chassis 2, the CTP battery pack 5 and the skateboard chassis 2, and further improving production efficiency and product quality consistency.

[0027] The materials and types of the first fastener 4 and the second fastener 9 are not limited in the embodiment of the utility model, which can be a bolt, a rivet or other fastening devices that can realize reliable connection. Of course, the first fastener 4 and the second fastener 9 can also adopt other assembly modes of relative positions, for example, staggered assembly or assembly at a certain inclination angle relative to the horizontal or vertical direction of the skateboard chassis 2. The assembly mode of different relative positions does not affect the realization of the basic function of the skateboard chassis body side beam structure of the utility model.

[0028] As an optional embodiment, the skateboard chassis 2 further comprises a second cavity 8, which is enclosed by the upper side beam and three partition beams arranged inside the skateboard chassis 2.

[0029] The second cavity 8 is enclosed by the upper side beam and three partition beams arranged inside the skateboard chassis 2, which provides multiple possibilities for optimizing the overall performance of the skateboard chassis 2. For example, some small electronic control units, sensor modules, and part of auxiliary power equipment lines can be arranged in the second cavity 8. At the same time, these components can be better protected in the second cavity 8 to avoid being collided and interfered by the outside world, which is conducive to optimizing the space layout inside the skateboard chassis 2 and thus improves the integration level of the skateboard chassis 2. The specific shape, material and arrangement position of the three partition beams and the shape and size of the second cavity 8 are not limited in the embodiments of the present application, as long as they can be enclosed to form a cavity.

[0030] In this embodiment, the design of the second cavity 8 enriches the functions of the skateboard chassis 2, optimizes the space utilization, enhances the practicability of the skateboard chassis 2, and makes it better adapt to the diversified requirements of the chassis performance of modern vehicles.

[0031] Of course, whether the second cavity 8 is arranged inside the skateboard chassis 2 does not affect the realization of the basic functions of the skateboard chassis body side beam structure of the present application.

[0032] As an optional embodiment, as shown in Figure 2 The second fastener 9 comprises a bolt 92 and a nut 91. A first assembly hole is arranged in the upper side beam constituting the second cavity 8, a second assembly hole is arranged in the body side beam 1 at a position corresponding to the first assembly hole, and the bolt 92 is connected with the nut 91 arranged at the corresponding position of the body side beam 1 through the first assembly hole and the second assembly hole.

[0033] In this embodiment, the first assembly hole is arranged on the upper side of the second cavity 8, and the second assembly hole is arranged at the corresponding position of the side beam 1. The bolt 92 passes through the two assembly holes and is connected with the nut 91 at the side beam 1, thereby realizing the stable combination of the side beam 1 and the skateboard chassis 2. Compared with some complex connection modes, the simple and direct bolt 92 and nut 91 connection is easy to operate and master, can improve the assembly efficiency, and reduce the production cost. In addition, in the subsequent maintenance and repair process of the vehicle, when the side beam 1 and the skateboard chassis 2 need to be disassembled or reassembled, the connection mode is also convenient to operate, which provides convenience for the subsequent repair work. At the same time, since the first assembly hole is arranged in the second cavity 8, when the vehicle is subjected to external forces such as vibration and impact during operation, the structure in the second cavity 8 can provide better support and constraint for the bolt 92. Compared with being arranged at other positions, the second cavity 8 itself can provide a certain degree of protection for the bolt 92, reduce the erosion and pollution of dust, moisture, sundries and the like to the assembly hole and the fastener, reduce the probability of problems such as wear, corrosion or jamming of the connecting components caused by foreign matters, prolong the service life of the fastener, and thereby enhance the long-term stability of the connection between the side beam 1 and the skateboard chassis 2.

[0034] In some optional embodiments, the materials of the bolt 92 and the nut 91 can also be optimized. For example, alloy steel material is selected. Such material has higher strength and hardness, can bear greater tension and shear force, and further enhances the reliability of the connection. At the same time, the surfaces of the bolt 92 and the nut 91 can be subjected to rust-proof treatment, such as zinc plating, Dacromet coating and the like, to prevent the connection performance from being reduced due to rust in a humid or harsh environment, and prolong the service life thereof. The specific positions of the above-mentioned first assembly hole and the second assembly hole are not limited in the embodiments of the present application.

[0035] In this embodiment, the connection structure of the bolt 92 and the nut 91 realizes the reliable connection between the side beam 1 and the skateboard chassis 2, improves the stability of the vehicle structure, and takes into account the convenience of assembly and maintenance. Of course, in the embodiments of the present application, the number of the above-mentioned bolt 92, nut 91 and assembly hole is not limited, and can be any number, any position of multiple bolts 92, nuts 91 and assembly holes. In some optional embodiments, the first assembly hole can also be arranged at other positions, that is, the bolt 92 and the nut 91 can realize the connection between the skateboard chassis 2 and the side beam 1 without passing through the first cavity 3. Of course, in addition to the bolt 92 and the nut 91, other fasteners can also be used, such as rivets, welding studs or the combination of pins and keys, and the selection of different types of fasteners does not affect the realization of the basic function of the skateboard chassis and side beam structure of the present application.

[0036] As an optional implementation, the connection part of the side beam 1 and the slide plate chassis 2 is provided with a sealing structure 7.

[0037] In this embodiment, the sealing structure 7 can effectively prevent dust, moisture, sundries and corrosive substances from the outside from entering the connection gap between the side beam 1 and the slide plate chassis 2. To some extent, it blocks the invasion of water, mud and dust into the connection part, reduces the risk of rust and corrosion caused by these adverse factors, keeps the connection part clean and dry, and improves the long-term reliability of the connection between the side beam 1 and the slide plate chassis 2.

[0038] The form of the sealing structure 7 can be various. Sealing foam with good elasticity and compressibility can be used, or rubber sealing gasket with good elasticity and sealing performance can be used. The material of the rubber sealing gasket can be selected according to the use environment and working conditions of the vehicle, such as high-temperature-resistant fluororubber material in high-temperature environment, and cold-resistant silicone rubber material in cold regions, to ensure that the sealing gasket can maintain good sealing performance under different conditions. In addition to rubber sealing gasket, sealing glue can also be used for sealing. The sealing glue can form a continuous sealing layer at the connection part, with good adhesion and filling properties. In some special application scenarios, a labyrinth sealing design similar to the above bearing structure can also be used. The connection part of the side beam 1 and the slide plate chassis 2 is designed with a protrusion and a groove structure that matches each other, forming a tortuous sealing channel. When external substances try to enter the connection part, they will be constantly blocked in the labyrinth channel, and their energy will gradually be consumed, making it difficult to penetrate the sealing structure 7. This design can provide more reliable sealing effect in cases where sealing requirements are extremely high, further improving the protection performance of the vehicle, and at the same time, the mounting surface and the sealing surface of the upper and lower bodies are on the same plane, which can also improve the sealing performance.

[0039] In this embodiment, the sealing structure 7 is provided at the connection part of the side beam 1 and the slide plate chassis 2, which to some extent reduces the influence of external adverse factors on the stability of the connection part, improves the durability and reliability of the connection part, and further improves the safety and service life of the entire vehicle.

[0040] Of course, in some optional embodiments, other ways can also be used to replace the sealing structure 7 to achieve the effect of improving the stability of the connection part of the side beam 1 and the slide plate chassis 2, such as using high-precision processing technology to manufacture the mating surface of the connection part, improving the flatness and roughness of the connection part of the side beam 1 and the slide plate chassis 2 to a high precision, designing special connection structure, such as using dovetail groove connection, mortise and tenon connection or embedded connection instead of traditional plane connection, or using higher strength materials to manufacture the side beam 1 and the slide plate chassis 2, etc.

[0041] As an optional embodiment, the sealing structure 7 is sealing foam.

[0042] In this embodiment, the sealing foam is a material with good elasticity and compressibility. When the body side beam 1 and the skateboard chassis 2 are connected by fasteners, the sealing foam will be extruded at the connection site, and the internal cell structure can be elastically deformed to tightly fill the connection gap. This feature makes the sealing foam effectively prevent dust, moisture, air and other impurities from entering the connection site. Compared with the general sealing structure 7, the sealing foam has better elasticity and compressibility, can maintain good sealing performance under different assembly pressures, and has relatively low cost, which can effectively reduce production cost in mass production. At the same time, the installation of the sealing foam is more convenient, and it does not need to be accurately applied and wait for the curing process like the sealant, only need to place the sealing foam of appropriate size at the connection site, which improves the assembly efficiency.

[0043] In some optional embodiments, in order to further improve the installation position accuracy and firmness of the sealing foam, a special groove or clamping groove can be designed at the connection site to embed the sealing foam, preventing it from shifting or falling off during assembly.

[0044] In this embodiment, the sealing foam is used as the sealing structure 7 of the connection site of the body side beam 1 and the skateboard chassis 2, which reduces the influence of external adverse factors on the stability of the connection site of the skateboard chassis body side beam structure, improves the durability and reliability of the connection site, and also has certain advantages in cost control and assembly efficiency.

[0045] Of course, other materials can also be used instead of sealing foam as sealing structure 7, such as rubber seals, sealants or graphite sealing materials, etc. Different sealing materials do not affect the realization of the basic function of the skateboard chassis body side beam structure of the utility model.

[0046] As an optional embodiment, as shown in Figure 1 The first fastener 4 and the second fastener 9 are bolts.

[0047] In this embodiment, the threaded cooperation of the bolt and the nut can provide reliable fastening force. During vehicle operation, various forces in different directions will be generated, such as inertial force and impact force generated by acceleration, braking, turning and bumping. Taking M12 bolt as an example, the threaded design thereof can withstand relatively large tensile force and shear force. When the vehicle is suddenly braked, the connection between the side beam 1 and the skateboard chassis 2 needs to resist a large forward inertial force, and the fastening effect of the bolt can effectively prevent the two from separating or relatively displacing. At the same time, the bolt is selected as the fastener, which only needs to pass through the corresponding assembly hole and then tighten the nut to complete the connection, and the operation is relatively simple and does not require complex special equipment. On the vehicle production line, this convenient installation method can improve the assembly efficiency and reduce the production cost.

[0048] Of course, in some optional embodiments, other fasteners can also be used, such as rivets, welding studs or the combination of pins and keys, and the selection of different types of fasteners does not affect the realization of the basic functions of the skateboard chassis side beam structure of the utility model.

[0049] As an optional embodiment, the CTC battery compartment 6 is also provided with a reinforcing rib structure distributed along the inner wall of the CTC battery compartment 6.

[0050] In this embodiment, the reinforcing rib structure distributed along the inner wall of the CTC battery compartment 6 enhances the overall rigidity and strength of the CTC battery compartment 6 to some extent. The specific form and layout of the reinforcing rib structure are not limited in the embodiments of the utility model, and the shape thereof can be various forms, for example, common straight strip, grid or wave shape, etc. The straight strip reinforcing rib performs well when bearing unidirectional large tensile force or pressure, can effectively enhance the strength of the CTC battery compartment 6 in a specific direction, and is suitable for local reinforcement of the CTC battery compartment 6 in some main stress directions. The grid reinforcing rib can provide all-round support, so that the CTC battery compartment 6 has relatively balanced rigidity in all directions, has an advantage in coping with complex and changeable stress conditions, can better disperse stress concentration points and prevent local excessive deformation. The wave-shaped reinforcing rib has a unique effect in absorbing and dispersing vibration energy, can effectively reduce the influence of vehicle vibration on the battery compartment 6 and the battery cell, and is particularly suitable for battery systems which are sensitive to vibration. In terms of material selection, the reinforcing rib usually adopts high-strength and good corrosion-resistant materials. Common ones are high-strength aluminum alloy, carbon fiber reinforced composite material, etc.

[0051] In this embodiment, the reinforcing rib structure in the CTC battery compartment 6 effectively resists various external forces during vehicle operation, improves the rigidity and strength of the CTC battery compartment 6, enhances the structural stability of the battery compartment 6 under complex working conditions, protects the safety of the internal battery cell, and thus improves the reliability and durability of the entire skateboard chassis side beam structure.

[0052] Of course, in other embodiments of the present application, other processes can also be used, for example, a protective coating is applied to the surface of the battery compartment 6, and a buffer material such as a rubber pad, foam plastic or honeycomb structure material can also be provided at the impact-prone parts inside or outside the battery compartment 6.

[0053] As an optional embodiment, the upper beam, the lower beam, the cross beam, the first longitudinal beam and the second longitudinal beam are made of aluminum alloy material.

[0054] In this embodiment, the aluminum alloy has a lower density, and compared with the traditional steel structure beam, the overall weight of the skateboard chassis 2 can be reduced under the condition of ensuring the same strength and rigidity, and at the same time, a dense oxide film is naturally formed on the surface of the aluminum alloy, which can effectively resist the corrosion of corrosive substances such as moisture, oxygen, acid and alkali in the external environment, and reduce the risk of structural damage and performance decline caused by corrosion.

[0055] Of course, carbon fiber composite material, magnesium alloy or steel can also be selected to replace the aluminum alloy, and the selection of different materials for the upper beam, the lower beam, the cross beam, the first longitudinal beam and the second longitudinal beam does not affect the realization of the basic function of the skateboard chassis body beam structure.
