Description

Technical Field

[0001] This utility model belongs to the field of shielding cover technology, specifically relating to a shielding cover for a sensor in a new energy vehicle. Background Technology

[0002] In today's automotive industry, which is rapidly developing towards intelligence and automation, autonomous driving and driver assistance functions have become core technology areas. Sensors, such as millimeter-wave radar and ultrasonic radar, are key components for realizing these functions, and their stability and accuracy directly determine the reliability and safety of autonomous driving and driver assistance systems.

[0003] However, with the increasing complexity of automotive electronic systems and the growing number of onboard electronic devices, the electromagnetic environment inside vehicles is becoming increasingly harsh. In such an environment, sensors are highly susceptible to electromagnetic interference. Electromagnetic interference can cause deviations, distortions, or even loss of signals received by sensors, severely affecting the accurate transmission of sensor signals and ultimately reducing detection accuracy.

[0004] To ensure the stable and accurate operation of sensors, shielding covers have been developed. Shielding covers effectively prevent sensors from being affected by external electromagnetic interference. Their principle is based on the reflection and absorption properties of metallic materials to isolate the sensor from the external electromagnetic environment. By installing shielding covers on sensors, the impact of electromagnetic interference on sensor signal transmission can be significantly reduced, ensuring accurate signal transmission, thereby improving detection accuracy and ensuring the reliable operation of autonomous driving and driver assistance functions in vehicles.

[0005] Although shielding covers have solved the electromagnetic interference problem of sensors to some extent, with the continuous improvement of sensor performance requirements and the increasing complexity of the electromagnetic environment, existing shielding covers still face many challenges in terms of design and material application. For example, the shielding effect needs to be further improved, the installation and fixing effect of the shielding cover and the sensor and the ease of installation and removal, and production costs are all issues that need to be addressed. Summary of the Invention

[0006] The purpose of this utility model is to provide a sensor shielding cover for new energy vehicles, which aims to solve the technical problems of insufficient shielding effect, unstable installation and fixation of the shielding cover and sensor, insufficient ease of installation and removal, and high production cost in the existing technology.

[0007] To achieve the above objectives, this utility model provides a sensor shielding cover for new energy vehicles, comprising a metal cover, elastic buckles, and support feet. The cover, elastic buckles, and support feet are integrally formed from a single flat plate. The cover has a nickel layer with a thickness of 2.5-3.5 micrometers, and on the nickel layer, a bright tin layer with a thickness of 2.5-3.5 micrometers is provided. Dovetail blocks are formed at the connecting parts of the cover, and a dovetail groove is formed between every two dovetail blocks.

[0008] Preferably, the cover body has a pre-drilled hole on the side symmetrical to the side with the dovetail block.

[0009] Preferably, the dovetail blocks at the connecting parts of the cover are alternately engaged.

[0010] Preferably, the cover has heat dissipation grooves on both sides perpendicular to the reserved holes.

[0011] Preferably, the elastic buckle is disposed in the reserved hole, and its bottom is connected to the cover body. The elastic buckle is inclined to the cavity formed after the cover body is formed, and part of it is located in the cavity formed by the cover body. The elastic buckle has elasticity.

[0012] Preferably, the support leg is L-shaped, with the shorter section connected perpendicularly to the cover and the other section parallel to the cover.

[0013] Preferably, the lower end of the section of the support leg that is parallel to the cover body is provided with a protrusion.

[0014] Preferably, the support leg has a vertical mounting hole in the middle that opens downwards and passes through the support leg.

[0015] The above-mentioned technical solutions in the sensor shielding cover for new energy vehicles provided in this embodiment of the utility model have at least one of the following technical effects:

[0016] This utility model discloses a sensor shielding cover for new energy vehicles. The nickel layer, with its excellent conductivity and magnetism, initially shields electromagnetic waves while simultaneously improving the bonding strength between the cover and the bright tin layer. The bright tin layer further reflects and absorbs electromagnetic waves, and the synergy between the nickel and bright tin layers further enhances the shielding effectiveness of the cover. Simultaneously, the combined corrosion resistance of nickel and bright tin provides long-term protection for the shielding cover. The good solderability of the bright tin layer improves welding quality, ensuring electrical connections and structural stability. The bright appearance of the bright tin layer enhances the aesthetics of the shielding cover, making it more harmonious with the vehicle's interior environment. The combination of the nickel layer and the bright tin plating further enhances the shielding effectiveness of the cover and significantly improves its corrosion resistance, weldability, and appearance quality.

[0017] This utility model discloses a sensor shielding cover for new energy vehicles. Elastic buckles strengthen the fixation between the sensor and the shielding cover, preventing displacement during vehicle operation. The dovetail block and dovetail groove cooperate to increase the contact area and enhance the connection strength through a serrated interlocking structure, dispersing stress, reducing the risk of cover breakage, and restricting relative movement within the plane. This ensures structural stability of the cover under vibration and impact conditions, while also improving the sealing effect and preventing electromagnetic leakage. With the elastic buckles and the cooperation of the dovetail block and dovetail groove at the cover connection, the fixing strength between the sensor and the shielding cover, as well as the strength of the cover connection, can be strengthened, improving the overall structural stability and sealing effect.

[0018] This utility model discloses a sensor shielding cover for new energy vehicles. The protruding parts of the support legs enhance the connection strength between the shielding cover and the mounting base, ensuring the shielding cover remains stable during vehicle vibration and guaranteeing the shielding effect. The vertical mounting holes increase adaptability, accommodating more mounting bases and making installation more flexible. At the same time, the vertical mounting holes reduce the rigidity of the support legs, enhance their flexibility, prevent breakage, and also reduce weight to some extent. Furthermore, they disrupt the conditions for static electricity accumulation to a certain extent, preventing electrostatic discharge and protecting electronic components such as radar sensors from damage caused by static electricity. With the cooperation of the protruding parts of the support legs and the mounting holes, the connection between the shielding cover and the mounting base is optimized, meeting various installation requirements and improving the overall performance of the shielding cover.

[0019] This utility model discloses a sensor shielding cover for new energy vehicles. Through the design of the shielding cover structure, it can be manufactured from a single piece of metal through a one-piece forming process of punching and bending, which greatly reduces production costs. The simplified production process reduces the number of parts and assembly steps, eliminating the need for complex splicing processes and effectively saving material and labor costs.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

[0031] In this embodiment of the invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this embodiment of the invention according to the specific circumstances.

[0032] In one embodiment of this utility model, such as Figure 1-3 As shown, a sensor shielding cover for a new energy vehicle includes a cover body 10, elastic buckles 20, and support legs 30. The cover body 10 is formed by bending a metal cover sheet and connecting the ends. The top of the cover body 10 is open, and the bottom is connected to the support legs 30. The elastic buckles 20 are set on the inner side wall of the cover body 10. The metal cover sheet, elastic buckles 20, and support legs 30 are integrally formed from a single piece of metal plate. The cover body 10 has a 2.5-3.5 micrometer thick nickel layer, and on the nickel layer, a 2.5-3.5 micrometer thick bright tin layer. The ends of the metal cover sheet that are connected are all formed with dovetail blocks 12 and dovetail grooves 13, and the dovetail blocks at one end and the dovetail grooves at the other end are inserted and connected. The side of the cover body 10 opposite to the side with the dovetail blocks 12 has a reserved hole 11. The end of the elastic buckle 20 is connected to the cover body 10, and the buckle body of the elastic buckle 20 is correspondingly set at the reserved hole 11.

[0033] The cover 10, elastic buckle 20, and support leg 30 are made of metal materials with good shielding performance. The metal material can be nickel silver or tinplate. It is formed by a whole piece of metal plate through punching and bending processes, which greatly reduces the production cost. The simplified production process reduces the number of parts and assembly processes, and does not require complicated splicing processes, effectively saving material and labor costs.

[0034] The surface of the cover 10 is first electroplated with a nickel layer of 2.5-3.5 micrometers thickness. On the basis of the nickel plating layer, a bright tin layer of 2.5-3.5 micrometers thickness is then electroplated. The thickness of the nickel layer and the bright tin layer is preferably 3 micrometers. With the cooperation of the nickel layer and the bright tin plating layer, the shielding effectiveness of the cover is further enhanced, and the corrosion resistance, welding performance and appearance quality of the shielding cover can be significantly improved.

[0035] The cover 10 is fitted onto the sensor 40, and the support leg 30 is connected to the mounting base 50.

[0036] like Figure 1 As shown, after punching and bending a single metal sheet, the metal sheets are joined to form a rectangular shield 10. Dovetail blocks 12 are formed at the contact points of the shield 10, and dovetail grooves 13 are formed between every two dovetail blocks 12. The dovetail blocks 12 at both ends of the shield 10 are alternately distributed, so that after the shield 10 is formed, the dovetail block 12 on one side can engage with the dovetail groove 13 on the other side. Through the cooperation of the dovetail blocks 12 and the dovetail grooves 13, compared with the traditional shield formed directly by bending, the contact area at the connection of the shield 10 is increased. When subjected to external forces, stress is dispersed, reducing the risk of breakage at the connection, and limiting the relative sliding and rotation of the connection of the shield 10 in the plane, making the connection more stable. Under dynamic load environments such as vibration and impact, it can effectively reduce the loosening of the connection and ensure the stability of the overall structure.

[0037] The cover 10 has a reserved hole 11 on the other side opposite to the side with the dovetail block 12. The cover 10 has heat dissipation grooves 14 on the two sides perpendicular to the reserved hole 11. The heat dissipation grooves 14 serve to dissipate heat from the sensor 40.

[0038] The reserved hole 11 is provided with an elastic buckle 20. The bottom of the elastic buckle 20 is connected to the cover 10. The elastic buckle 20 is inclined into the cavity formed after the cover 10 is formed. Part of the elastic buckle 20 is in the cavity formed by the cover 10. When the sensor 40 is placed in the cover 10, the elastic buckle 20 is squeezed by the sensor 40 and deformed, and is completely in the reserved hole 11. The atomic or molecular structure of the elastic buckle 20 will generate a force to resist deformation and try to return to the initial state due to deformation, that is, elastic force. The elastic buckle 20 applies pressure to the sensor 40 to strengthen the fixing strength between the sensor 40 and the cover 10.

[0039] The support leg 30 is L-shaped, with its shorter side perpendicularly connected to the cover 10 and the other side parallel to the cover 10. A protrusion 31 is provided at the lower end of the side of the support leg 30 parallel to the cover 10. A vertical opening 32 is provided in the middle of the support leg 30, extending downward through the support leg 30. The support leg 30 is fixed to the mounting base 50 through the mounting hole 32. The protrusion 31 of the support leg 30 enhances the connection strength between the shielding cover and the mounting base 50, ensuring the shielding cover is stable when the vehicle is vibrating and guaranteeing the shielding effect. The vertical mounting hole 32 increases adaptability, allowing it to accommodate more mounting bases 50 and making installation more flexible. At the same time, the vertical mounting hole 32 reduces the rigidity of the support leg 30, enhances its flexibility, prevents the support leg 30 from breaking, and can also reduce weight to a certain extent. It also disrupts the conditions for static electricity accumulation to a certain extent, preventing electrostatic discharge caused by static electricity accumulation and preventing static electricity from damaging electronic components such as the radar sensor 40. With the cooperation of the protrusion 31 and the mounting hole 32 of the support leg 30, the connection between the shielding cover and the mounting base 50 is optimized, which can meet various installation requirements and improve the overall performance of the shielding cover.

[0040] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
