That is to say, welding can be carried out along the boundary of the kidney-shaped hole and the boundary of the contact position between the joint and the main beam 5 to form a weld seam. The setting of the kidney-shaped hole can increase the welding area of the weld seam and enhance the bonding strength between the joint and the main beam 5.

[0077] In one embodiment, the wiring harness 4 is arranged inside the auxiliary beam 6.

[0078] It can be understood that the wiring harness 4 can be only arranged in the auxiliary beam 6, and the main beam 5 can be not provided with the wiring harness 4, so that the main beam 5 can be designed as a solid structure, enhancing the strength of the main beam 5 to improve the strength of the chassis structure 1.

[0079] In one embodiment, multiple auxiliary beams 6 are arranged in segments in at least one of the front section 18, the middle section 19 and the rear section 20 of the chassis structure 1.

[0089] Among them, the electrical connection means connecting the male terminal 7 and the female terminal 8 through a conductor, a wire, a contact or other conductive medium to form an electric current path, so as to realize the transmission of electrical signals or the transfer of electrical energy.

[0090] It can be understood that the male terminal 7 is electrically connected to the wire harness 4 inside the first beam 61, and the female terminal 8 is electrically connected to the wire harness 4 inside the second beam 62, which is equivalent to realizing the electrical connection of the wire harness 4 inside the corresponding first beam 61 and second beam 62 through the male terminal 7 and the female terminal 8.

[0091] It can be understood that by providing the male terminal 7 on the first beam 61 and the female terminal 8 on the second beam 62, through the cooperation and docking of the male terminal 7 and the female terminal 8, the electrical connection of the wire harness 4 in the corresponding first beam 61 and second beam 62 is made more convenient and the docking is more accurate.

[0095] In one embodiment, please refer to Figure 9A , Figure 9B , Figure 10A , Figure 10B , the female terminal 8 is sleeved on the circumferential outer side of the wire harness 4 in the second beam 62.

[0096] Among them, one second beam 62 can be provided with two female terminals 8, which are respectively located at both ends of the second beam 62 along the length direction.

[0100] In one embodiment, the inner protection layer 9 is a rubber structure.

[0101] Among them, the material of the rubber structure can be fluororubber or polyurethane rubber.

[0102] Among them, the high-temperature resistance range of fluororubber is from 200°C to 250°C, and the loss factor range is from 0.05 to 0.3.

[0103] Among them, the high-temperature resistance range of polyurethane rubber (PU) is from 150°C to 200°C, and the loss factor range is between 0.1 and 0.5.

[0104] It can be understood that when better high-temperature resistance performance is required, fluororubber can be used to prepare the vibration absorption layer 3; when better vibration damping performance is required, polyurethane rubber can be used to prepare the vibration absorption layer 3.

[0105] In one embodiment, the loss factor range of the rubber structure is from 0.05 to 0.5.

[0106] Among them, the loss factor of the rubber structure can be, but is not limited to, 0.05, 0.1, 0.2, 0.3, 0.4, 0.5.

[0108] Among them, the high-temperature resistance range of the rubber structure can be from 150°C to 250°C to improve the thermal stability of the rubber structure.

[0109] It can be understood that the loss factor is used to measure the damping performance of the rubber structure. The larger the loss factor, the better the vibration absorption performance of the rubber structure. The loss factor range of 0.05 to 0.5 further improves the vibration absorption performance of the vibration absorption layer 3.

[0110] In one embodiment, please refer to Figure 2B , the vibration absorption layer 3 further includes an outer protective layer 10, and the outer protective layer 10 is arranged around the beam body 2.

[0111] It can be understood that the outer protective layer 10 is located outside the beam body 2. Since the beam body 2 replaces the skeleton 13 in the wire harness 4, the skeleton 13 is removed, reducing the cost; at the same time, the outer protective layer 10 is located outside the beam body 2, protecting the wire harness 4 from physical and chemical damage from the external environment and ensuring the mechanical safety and durability of the wire harness 4.

[0112] In one embodiment, please refer to Figure 2A , the vibration absorption layer 3 is arranged between the beam body 2 and the wire harness 4.

[0113] It can be understood that the wire harness 4 is arranged inside the beam body 2. The wire harness 4 itself has a vibration absorption layer 3, and the vibration absorption layer 3 is located on the outermost side of the wire harness 4, which not only protects the wire harness 4 from physical and chemical damage from the external environment but also enhances the vibration absorption ability of the beam body 2.

[0114] In one embodiment, the wire harness 4 includes a wire core 11, a protective layer 12, and a skeleton 13. The protective layer 12 is disposed around the wire core 11, the skeleton 13 is disposed around the protective layer 12, and the vibration damping layer 3 is disposed around the skeleton 13.

[0116] In one embodiment, the material for preparing the vibration damping layer 3 is waterproof silicone, and the material for preparing the protective layer 12 is polyethylene.

[0117] It can be understood that when the protective layer 12 does not have the vibration damping function, the vibration damping layer 3 is disposed around the outside of the wire harness 4. The vibration damping layer 3 is made of waterproof silicone material. In addition to increasing the vibration damping ability, it also needs to protect the wire harness 4 from physical and chemical damages of the external environment and ensure the mechanical safety and durability of the wire harness 4.

[0118] In one embodiment, please refer to Figure 11A and Figure 11B , the wire harness 4 is a three-core wire harness. The three-core wire harness includes three wire cores 11, and a filling portion 15 for eliminating mutual inductance is filled between adjacent wire cores 11.

[0119] Among them, the three wire cores 11 can be arranged in a symmetric triangular shape.

[0123] (2), More evenly distribute the load and reduce the phenomenon of current and voltage imbalance

[0124] (3), Reduce the use of materials for the wire harness 4 and reduce the material cost.

[0125] (4), Compared with the single-core wire harness 4, the three-core system has lower power loss when transmitting the same power.

[0126] In one embodiment, the wire harness 4 can also be a single-core wire harness 4, which will not be elaborated here.

[0127] In one embodiment, a metal shielding layer 14 is further disposed around the outside of the wire core 11.

[0128] It can be understood that the metal shielding layer 14 is used to shield electromagnetic interference and prevent interference with other devices.

[0129] In one embodiment, a heat dissipation channel is integrated inside the beam body 2 , and the heat dissipation channel is used to conduct away the heat generated by the wiring harness 4 .

[0130] It is understandable that the heat dissipation channel integrated in the beam body 2 is used to increase the heat dissipation effect to avoid the heat generated by the wiring harness 4 being difficult to dissipate in the beam body 2 and causing abnormalities.

[0131] In one embodiment, at least one of the following is also included:

[0132] The front section 18 of the chassis structure 1 is integrated with an electric defroster and / or a steering motor;

[0133] The middle section 19 of the chassis structure 1 is integrated with a battery pack;

[0135] Among them, the all-in-one controller integrates multiple electronic control units, and the electronic control unit includes a motor controller or a charging management component.

[0136] It can be understood that by making the chassis structure 1 a segmented modular design, the electric defroster in the front section 18 is used to defrost the vehicle windshield, the steering motor is responsible for driving the steering system, and the battery pack in the middle section 19 is used to provide power, which can improve production efficiency and maintenance convenience.

[0137] In one embodiment, a diagonal bracing structure is provided at the connection between the main beam 5 and the auxiliary beam 6 , and the diagonal bracing structure is arranged away from the main beam 5 .

[0138] It can be understood that the diagonal bracing structure can realize continuous arrangement of the wire harness 4 in the beam body 2 , which facilitates the routing of the wire harness 4 .
