Description
Technical Field
[0001] This invention relates to the field of electric vehicle door panel technology, and more particularly to a convenient door panel for electric vehicles. Background Technology
[0002] Electric vehicle door panels are a core component of electric vehicle doors. They not only need to provide protection and a mounting base for the internal wiring harnesses and electrical components, but also need to have practical functions such as storage, dust protection, and lighting. Their ease of assembly, structural stability, and ease of maintenance directly affect the production efficiency, user experience, and safety performance of electric vehicles. Therefore, developing an electric vehicle door panel that integrates convenient assembly, neat wiring, multi-functional practicality, and safety warnings is an important direction for industry development. Existing electric vehicle door panels suffer from several drawbacks. Traditional clips require manual alignment with the door panel's metal holes, which is prone to misalignment, resulting in uneven gaps and excessive step differences between the panel and the metal.

The connecting pins 17 are tapered, and multiple equidistant elastic retaining plates are installed on their outer surfaces. One end of each connecting block 16 has a locking groove, and the inner wall of the locking groove has multiple slots that mate with the elastic retaining plates. Another end of each connecting block 16 also has a guide opening for easy removal of the connecting pins 17. The locking groove on the connecting block 16 facilitates initial connection between the two door panels and the connecting pins 17. The slots and elastic retaining plates engage to strengthen the fixation, and the guide opening facilitates removal of the connecting pins 17, reducing disassembly difficulty. The conical design of pin 17 facilitates quick insertion into the snap-fit groove of connecting block 16. The elastic snap-fit plate engages with the snap-fit groove to securely connect the two door panels, eliminating the need for complex bolt tightening and improving assembly efficiency. The bottom surface of the storage compartment of the second door panel 2 has an installation opening penetrating the first door panel 1. A guide cylinder 20 is installed on the bottom surface of the storage compartment within the installation opening, and a filter plate 19 is fixedly connected to the bottom surface of the storage compartment at the installation opening.

The magnetic block 23 allows for quick installation of the dustproof net 22. The dustproof net 22 effectively blocks external dust from entering the door panel, protecting internal wiring harnesses and components from dust corrosion and extending their service life. The magnetic block 23 facilitates quick adsorption and installation of the dustproof net 22 without the need for additional bolts or clips, simplifying the disassembly and replacement process. A smoke sensor 24 is installed on the upper part of the inner wall at the rear end of the first door panel 1. The smoke sensor 24 allows for real-time monitoring of the smoke concentration around the door panel; if an abnormality occurs, a timely warning can be triggered, improving the safety of electric vehicle use. The smoke sensor 24 is model RS-YG / YG2-N01.
[0020] Working principle: In this embodiment, the present invention also proposes a method for conveniently assembling door panels in electric vehicles, including the following steps: Step 1: First, attach the positioning pin 4 to the straight groove of the positioning plate 3 at the four corners of the inner side of the first door guard plate 1 to complete the pre-assembly of the positioning component; then, according to the wiring harness inside the door guard plate, slide the wiring harness clamp 7 in the slide rail 6, use the damping rubber block to fix the wiring harness clamp 7 in a suitable position, clamp the neat wiring harness and make it pass through the opening on the lamp holder 10; then, use the magnetic block 23 to adsorb and fix the dustproof net 22 to the corresponding position of the second door guard plate 2, close the box door 18 of the storage box, and make the elastic blocks on both sides of its rear end engage and fix with the storage box; Step two: Align the positioning component of the first door panel 1 with the preset installation position on the door. Using the double-stage guide ramp at the rear end of the positioning pin 4 to reduce insertion resistance, insert the positioning pin 4 into the door mounting hole. The elastic barbed locking claw 5 on the outer side of the positioning pin 4 retracts during insertion and elastically opens after full insertion, engaging with the inner wall of the door mounting hole, thus achieving a stable installation of the first door panel 1 and the door. Then, align the tapered connecting pin 17 on the second door panel 2 with the locking groove of the connecting block 16 of the first door panel 1. Using the tapered structure of the connecting pin 17, quickly insert it, causing the elastic locking plate on the outer side of the connecting pin 17 to engage with the locking groove on the inner wall of the locking groove, achieving a stable connection between the first door panel 1 and the second door panel 2. Finally, connect all electrical equipment wires and power on. Step 3: After the preparation is completed, press the dial ring 12 to drive the rotating block 13 to compress the spring 14 on the L-shaped plate 15, so that the dial ring 12 and the semi-circular rubber strip of the rotating block 11 are in contact. Rotate the dial ring 12 to drive the snap-fit cylinder 8 to rotate around the mounting base 9, and adjust the lighting angle of the lamp holder 10. After the adjustment is completed, release the dial ring 12, the spring 14 returns to its original position and pushes the rotating block 13 to press the dial ring 12 tightly, locking the angle of the lamp holder 10, thus completing the overall assembly and functional debugging of the door panel. Step 4: During the use of the door guard, the smoke sensor 24 monitors the smoke concentration around the door guard in real time. If the concentration exceeds the safety threshold, an alarm signal is triggered. When using the storage box, the door 18 can be opened by pressing the elastic latch of the door 18 to store items. Fine debris and dust in the storage box are filtered by the filter plate 19 and fall into the collection box 21 through the guide cylinder 20. The damping block on the inner wall of the guide cylinder 20 cooperates with the damping groove of the collection box 21 to prevent the collection box 21 from sliding accidentally. If the wiring harness layout needs to be adjusted, the position of the wiring harness clip 7 in the slide rail 6 can be slid. The damping rubber block ensures that the wiring harness clip 7 stays stably in the new position, ensuring that the wiring harness is always neat. Step 5: When maintenance or disassembly is required, first open the glove box door 18, clean out the debris inside the glove box, then pull out the collection box 21 inside the guide tube 20 for cleaning, and reset it after cleaning; if the dust screen 22 needs to be replaced, directly peel off the dust screen 22 adsorbed by the magnetic block 23, replace the new screen, and then re-adsorb and fix it by the magnetic block 23; if the two door panels need to be separated, use the guide port at one end of the connecting block 16 to press the elastic plate to make it disengage from the slot, and pull out the connecting pin 17 to separate the two door panels; if the first door panel 1 needs to be removed from the door, simply pull the hook-type locking claw 5 off forcefully and then replace it with a new hook-type locking claw 5.
