Description

Technical Field

[0001] This utility model relates to the field of sensor installation technology, and in particular to a mounting card structure, cover structure, mounting assembly, and vehicle sensor for vehicle-mounted sensors. Background Technology

[0002] With the rapid development of automotive intelligence and active safety technologies, onboard sensors, as core photoelectric detection components, have become crucial devices for improving driving safety and convenience. These sensors are typically installed in the area corresponding to the rearview mirror on the inside of the windshield. This location avoids obstructing the driver's view while accurately capturing key information such as light intensity and rainfall in the environment ahead. They possess two core functions: first, automatically adjusting the wiper frequency based on rainfall intensity, eliminating the need for manual shifting; and second, automatically controlling the headlights based on ambient light intensity, especially in scenarios with sudden changes in light, such as tunnel passages or at dusk / dawn / evening, providing a rapid response to ensure clear visibility. These two automated functions significantly reduce the frequency of manual operation by the driver, allowing them to focus on road condition assessment and vehicle control, effectively reducing the risk of traffic accidents caused by distracted driving.

[0003] From a structural perspective, the core assembly units of mainstream automotive sensors consist of three main components: the card, the cover, and the bracket. Among these, the assembly and fixing of the card and the cover is a critical step in ensuring the reliability of the sensor structure. Currently, the industry commonly uses a bolt-fastening assembly method, which involves using multiple micro-bolts to pass through the pre-drilled mounting holes in the card and the cover, and then tightening them with nuts to achieve a fixed connection between the two.

[0004] However, this traditional bolt-fastening assembly method reveals many unavoidable defects in actual production and use, seriously affecting the sensor's assembly efficiency, production cost, and reliability. Specifically, these defects manifest in the following aspects: First, the increased number of parts raises production and management costs. In addition to the core clips and covers, bolt fastening requires additional fasteners such as bolts and nuts, and in some scenarios, washers are needed to improve the fastening effect. This not only increases the manufacturing process of components (such as fastener processing and surface rust prevention treatment), but also increases the difficulty of supply chain management. The consistency of fastener specifications and inventory quantities need to be managed separately, and problems such as missing or mismatched fasteners are prone to occur during assembly, leading to decreased production efficiency and indirectly increasing overall production costs.

[0005] Secondly, the assembly process is cumbersome, making it impossible to achieve rapid assembly in one go. The existing assembly process requires two steps: First, the operator must hold a card and precisely align it with the mounting holes on the cover, then pass the bolt through the holes and tighten the nut to secure them. Second, the assembled card-cover assembly is then reassembled with the bracket (usually using clips or another set of bolts). This step-by-step assembly method increases the assembly time for each sensor during batch assembly on the production line, severely restricting production cycle time. Furthermore, the multi-step operation increases the probability of human error, such as insufficient bolt tightening or misalignment of mounting holes, which can affect the stability of subsequent use.

[0006] Third, the bolts are prone to loosening and falling off, leading to sensor displacement failure. The continuous vibrations generated during vehicle operation can cause the threaded connections of bolts and nuts to loosen over time, and in extreme cases, even the bolts may fall off. Once a bolt falls off, the fixing relationship between the card and the cover fails, causing relative displacement or even separation. On one hand, the falling cover leaves the card without its seal, allowing external dust and moisture to directly enter and damage the photoelectric chip. On the other hand, the card's displacement alters its detection angle and optical path, leading to decreased rainfall detection accuracy (e.g., misjudging rainfall amount) and inaccurate light intensity recognition (e.g., headlights turning on too early or too late), which can cause malfunctions such as erratic wiper operation and headlight control failure, posing potential risks to driving safety. Furthermore, a fallen bolt may also leave small parts inside the passenger compartment, which, if they enter other mechanical structures (such as the steering mechanism), could create additional safety hazards.

[0007] Fourth, the inconvenience of repair and disassembly increases after-sales maintenance costs. When a sensor malfunctions and requires disassembly and repair, the bolt tightening method requires the use of special tools (such as miniature screwdrivers and wrenches) to loosen the bolts in order to separate the card from the cover. This operation is cumbersome and prone to damage to the mounting holes and scratches on the card surface due to improper tool handling. This not only increases the labor costs of after-sales maintenance, but may also cause secondary damage during disassembly, making the sensor irreparable and requiring complete replacement, thus increasing the maintenance burden on users.

[0008] In summary, the existing bolt-fastening assembly method for the card and cover in automotive sensors suffers from multiple drawbacks, including numerous components, cumbersome assembly steps, susceptibility to displacement and failure, and inconvenient maintenance. It fails to meet the industrialization demands of "efficient assembly and low-cost production" for automotive parts, and also struggles to guarantee the structural reliability of sensors during long-term use. Currently, the industry has not yet proposed an effective solution that simultaneously achieves "rapid one-time assembly, structural stability, and no additional fasteners." There is an urgent need to optimize the card-cover assembly method through structural innovation to overcome current technological bottlenecks.

[0009] Currently, no effective solutions have been proposed for the problems in related technologies, such as the complex assembly method of cards and covers, the large number of parts, the inability to complete assembly in one go, and the displacement problem of vehicle-mounted sensors.

[0104] It should be noted that the detachable connection between the lower cover element and the upper cover element is a conventional technical method in this field, and will not be described in detail here.

[0105] like Figures 4-5As shown, the third snap-fit ​​unit 220 includes a plurality of third snap-fit ​​elements 221. The plurality of third snap-fit ​​elements 221 are disposed on the side of the cover unit 210 and are used to snap-fit ​​with the second snap-fit ​​unit 130 of the mounting card structure 100.

[0106] Specifically, several third latching elements 221 are latched to their respective second latching elements 131.

[0107] It should be noted that the third snap-fit ​​element 221 is fixedly connected to the cover unit 210, including but not limited to integral molding. It is generally obtained through machining.

[0108] It should be noted that the number of the third latching element 221 is equal to the number of the second latching element 131, that is, the third latching element 221 and the second latching element 131 correspond one-to-one.

[0109] The distribution of the third latching element 221 is the same as that of the second latching element 131, and will not be described again here.

[0110] In some of these embodiments, the third snap-fit ​​element 221 is a snap-fit ​​protrusion.

[0111] The advantage of this embodiment is that by using the third snap-fit ​​unit to snap-fit ​​the second snap-fit ​​unit, the mounting card structure and the cover structure can be fixed without additional assembly, reducing assembly steps and greatly reducing the number of parts used.

[0112] Example 3 This embodiment relates to the mounting assembly and vehicle-mounted sensor of this utility model.

[0113] like Figure 6 As shown, a mounting assembly for an on-board sensor includes a mounting card structure 100 as described in Embodiment 1, a cover structure 200 as described in Embodiment 2, and a mounting bracket structure 300. The cover structure 200 is snap-fitted to the mounting card structure 100; the mounting bracket structure 300 has the cover structure 200, and the mounting bracket structure 300 is snap-fitted to the mounting card structure 100.

[0114] It should be noted that the structure of the mounting bracket structure 300 is a conventional technical means in this field (largely the same as the mounting bracket in the mounting bracket and mounting assembly of the company's CN218661739U - mounting bracket for rain and light sensor), and will not be described in detail here.

[0115] like Figure 6 As shown, an on-board sensor includes a mounting assembly and a sensor structure as described above. The sensor structure is disposed inside the cover structure 200.

[0116] It should be noted that, in this utility model, the vehicle-mounted sensors include, but are not limited to, rain and light sensors.

[0117] The advantages of this embodiment are basically the same as those of Embodiment 1 and Embodiment 2, and will not be repeated here.

[0118] The above description is only a preferred embodiment of the present utility model and does not limit the implementation method and protection scope of the present utility model. Those skilled in the art should realize that all solutions obtained by equivalent substitutions and obvious changes made based on the description and illustrations of the present utility model should be included within the protection scope of the present utility model.
