Description

Technical Field

[0001] The utility model relates to the technical field of electric vehicles, in particular to an electric appliance component layout structure of an electric vehicle. Background Art

[0002] With the rapid expansion of the electric vehicle market and the increasing improvement of consumers' requirements for product quality, the existing installation and layout methods are difficult to meet the market demand and safety standards.

[0003] First of all, the disorder of the internal wiring harness of electric vehicles is a common problem. These wiring harnesses are intricate and complex. Not only do they lack a unified layout plan, but they are often randomly fixed in various corners of the vehicle body due to design defects or installation negligence, and are simply bundled with a large number of cable ties on the nearby iron parts.

[0004] The above-mentioned method not only affects the aesthetics inside the vehicle, but more importantly, it brings great inconvenience to the maintenance and inspection of the wiring harness. Once a vehicle breaks down and the wiring needs to be checked, maintenance personnel often need to spend a lot of time sorting out these intricate wiring harnesses, greatly reducing the maintenance efficiency. Secondly, the relative displacement phenomenon between electrical components is also a safety hazard that cannot be ignored. During the driving of an electric vehicle, especially on bumpy roads or sharp turns, the relative displacement between electrical components may cause the wiring harness to be squeezed, stretched or rubbed, thereby triggering electrical faults such as short circuits and open circuits. More seriously, this kind of friction may also generate sparks, increasing the risk of vehicle spontaneous combustion.

[0005] In addition, the random arrangement and connection of electrical components are not conducive to the heat dissipation of the electrical components themselves, and may even pose a threat to the safety of the driver during high-temperature driving.

[0006] In order to improve this situation and enhance the safety of electric vehicle products, it is urgent to develop a heat-dissipating electric appliance component layout structure for electric vehicles. Summary of the Utility Model

[0038] As Figures 1 to 5, which shows the layout structure of electric vehicle electrical components in an embodiment of the present utility model, including an inner windshield 7, a front panel assembly 16, and a front inner mudguard 17; a lining 1 is added inside the inner windshield 7, and the lining 1 is located between the front panel assembly 16 and the inner windshield 7 and above the front inner mudguard 17. A frame vertical pipe 8 is arranged at the rear side of the lining 1, and the frame vertical pipe 8 is assembled and connected with the lining 1; the windward surface of the front inner mudguard 17 is inclined, and an air outlet is arranged at the top of the front inner mudguard 17, and the air outlet faces the lining 1. The flowing air moves towards the lining 1 after passing through the air outlet; further included is: a main wire harness assembly 6 of the electric vehicle. The main wire harness assembly 6 passes through the back end of the lining 1 to form multiple branch circuits, and the multiple branch circuits are respectively plugged into corresponding electrical components, and limit clips are arranged in a matching manner on the circuits where each branch circuit is plugged into the corresponding electrical component.

[0039] In this embodiment, an outlet for the main wire harness assembly 6 to pass through is arranged on the lining 1, and at least one branch circuit limiting member is arranged at the side position of the outlet; the branch circuit is plugged into the corresponding electrical component after passing through the branch circuit limiting member.

[0040] In this embodiment, a frame bracket 15 is integrally connected to the pipe body of the frame vertical pipe 8, and a middle mounting point 13 corresponding to the frame bracket 15 is arranged at the central position of the lining 1; the lining 1 and the frame vertical pipe 8 are fixedly installed through the middle mounting point 13 and the frame bracket 15;
