Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, and in particular to a waterproof structure for a cover plate of a new energy intelligent driving high-precision positioning system. Background Technology

[0002] In intelligent driving technology for new energy vehicles, the high-precision positioning system is a core component for achieving accurate navigation, path planning, and autonomous driving control. The stability of its working environment directly affects the system's positioning accuracy and lifespan. Since vehicles encounter various liquid environments during operation, such as rainwater, car wash water, and dew, if the cover of the high-precision positioning system lacks sufficient waterproofing, moisture can penetrate the equipment, potentially causing short circuits, component corrosion, and other problems, severely impacting the reliability and safety of the intelligent driving system.

[0003] Currently, most existing waterproof cover structures employ single or double sealing designs, with limited selection of sealing materials and inadequate fit between the sealing surface and sheet metal, failing to meet the high-level waterproofing requirements of high-precision positioning systems. Therefore, there is an urgent need for a waterproof structure with multiple layers of protection, reliable sealing, and optimized structure to address the insufficient waterproofing performance of existing technologies. Utility Model Content

[0004] To address the technical problems existing in the background art, this utility model proposes a waterproof structure for the cover plate of a new energy intelligent driving high-precision positioning system.

[0005] This utility model proposes a waterproof structure for a cover plate of a high-precision positioning system for intelligent driving in new energy vehicles, including a top cover assembly and sheet metal; the top cover assembly and the sheet metal are fixedly connected by bolts, and the top cover assembly is a double-layer plate structure, which is distributed in a concentric ring and is nested from the outside to the inside.

[0006] The inner side of the sheet metal has a ring of rounded corner protrusions in the middle, and the sheet metal has three rings of waterproof sealing surfaces around its perimeter, which are distributed in concentric rings and are nested from the outside to the inside.

[0007] The first sealing surface is located on the outer ring with rounded corners, forming a seal with the sheet metal surface of the vehicle's roof;

[0008] The second sealing surface and the rounded corner protrusion form a rounded corner seal;

[0009] The third sealing surface is located on the inner ring with rounded corners, forming a seal with the sheet metal.

[0010] Preferably, the adhesive layer is a two-component polyurethane.

[0011] Preferably, the height of the rounded corner protrusion is 4mm.

[0012] Preferably, the first sealing surface is a seal formed by TPR waterproof strip and the sheet metal surface of the vehicle roof; the second sealing surface is a rounded corner seal formed by EPDM and sheet metal protrusions; and the third sealing surface is a seal formed by butyl tape and sheet metal.

[0013] Preferably, the bolt is located between the second sealing surface and the second sealing surface.

[0014] The waterproof structure of the cover plate for the high-precision positioning system for intelligent driving in new energy vehicles proposed in this utility model has the following beneficial effects:

[0015] By setting up three annular sealing surfaces, a progressively blocking waterproof barrier is formed, effectively preventing water intrusion under different working conditions and significantly improving the waterproof reliability of the high-precision positioning system. To meet the needs of different sealing surfaces, highly compatible sealing materials such as TPR waterproof strips, EFDI, and butyl tape are used to ensure stable and durable sealing performance on each surface, while also exhibiting good weather resistance and aging resistance. The double-layered concentric ring structure of the top cover assembly enhances overall strength; the 4mm high rounded corner protrusions on the sheet metal not only fit well with the sealing materials but also guide and block moisture; the reasonable placement of bolts avoids the risk of leakage, further improving the structure's sealing performance.

[0016] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0021] The embodiments of this utility model are described in detail below. Examples of these embodiments are illustrated in the accompanying drawings, wherein the same or similar symbols denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0022] like Figures 1-3The waterproof structure of the cover plate of the new energy intelligent driving high-precision positioning system shown includes a top cover assembly 4 and sheet metal. The top cover assembly 4 and the sheet metal are fixedly connected by bolts, and an adhesive layer is provided between the two. The adhesive layer is a two-component polyurethane, which can enhance the sealing and firmness of the connection between the top cover assembly 4 and the sheet metal.

[0023] The top cover assembly 4 has a double-layer plate structure, which is distributed in a concentric ring and is nested from the outside to the inside. This structural design can enhance the overall strength of the top cover assembly 4 and provide a more stable foundation for waterproof sealing.

[0024] The inner side of the sheet metal has a ring of rounded corner protrusions in the middle. The height of the rounded corner protrusions is 4mm. The rounded corner protrusions can not only work with the sealing material to form an effective seal, but also play a certain role in guiding and blocking moisture.

[0025] The sheet metal is provided with three annular waterproof sealing surfaces around its perimeter, distributed in a concentric ring shape, and sequentially fitted from the outside to the inside; through multiple seals, waterproofing is achieved at each level, greatly improving the reliability of waterproofing.

[0026] The first sealing surface 1 is located on the outer ring with rounded corners. It is a seal formed by the TPR waterproof strip and the sheet metal surface of the car body roof, which can initially block a large amount of rainwater, car wash water, etc. The TPR waterproof strip is installed on this sealing surface. The TPR waterproof strip is fixed to the sheet metal by a preset groove or adhesive method, and forms a seal by tightly fitting with the sheet metal surface of the car body roof.

[0027] The second sealing surface 2 forms a rounded corner seal with the rounded corner protrusion, specifically the rounded corner seal formed by EFDI and the sheet metal protrusion, which can further block a small amount of moisture passing through the first sealing surface 1; EPDM sponge strips are installed at this sealing surface, and EPDM is evenly covered on the surface of the rounded corner protrusion and the corresponding contact surface of the top cover assembly 4. After curing, it forms a tight rounded corner seal with the rounded corner protrusion of the sheet metal.

[0028] The third sealing surface 3 is located on the inner ring with rounded corners. It is a seal formed by butyl tape and sheet metal, serving as the last line of defense to effectively prevent moisture from entering the high-precision positioning system. Butyl tape is pasted on this sealing surface. The butyl tape has good adhesion and sealing properties, and it fits tightly against the corresponding surfaces of the sheet metal and top cover assembly 4 to form a seal.

[0029] Furthermore, the bolts are located between the second sealing surface 2 and the third sealing surface 3. This design prevents the bolt installation location from becoming a channel for moisture intrusion, ensuring the sealing of the bolt connection. Through the combination of bolted fastening and a two-component polyurethane adhesive layer, a firm connection is ensured between the top cover assembly 4 and the sheet metal, while also enhancing the overall structural sealing and stability, allowing it to withstand vibrations during vehicle operation.

[0030] The waterproof structure of the cover plate of the new energy intelligent driving high-precision positioning system in this embodiment, through the synergistic effect of the above three sealing surfaces, as well as reasonable structural design and material selection, can effectively block the intrusion of various moisture such as rainwater, car wash water, and dew, providing reliable waterproof protection for the new energy intelligent driving high-precision positioning system and ensuring its stable operation in complex environments.
