Description

Technical Field

[0001] This utility model relates to the field of sensor technology, and in particular to a protective structure for a sensor. Background Technology

[0002] Currently, tooling used in automotive parts assembly typically integrates multiple sensors to monitor process parameters and positioning accuracy in real time, ensuring correct procedures and consistent product quality. However, due to issues such as workpiece loading, mechanical vibration, impact, and common production site dust and oil contamination during assembly, sensors are susceptible to physical damage or environmental interference, leading to measurement errors, performance degradation, or even complete failure. This directly impacts the stability of the production system and the yield rate of products.

[0003] While existing technologies offer some sensor protection methods, most are complex in structure, costly to manufacture, or inconvenient to maintain, making them difficult to widely implement in the automotive manufacturing sector. Therefore, there is an urgent need for a sensor protection mechanism that is simple in structure, easy to install, inexpensive, and provides significant protection. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a sensor protection structure that is simple in structure, easy to install, low in cost, and has a significant protective effect.

[0005] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: A protective structure for a sensor includes a sensor and a sensor support. The sensor is mounted on the sensor support, and a sensor protective cover is detachably provided on the sensor support. A protective cavity is formed between the sensor protective cover and the sensor support. The sensor is disposed within the protective cavity, and a sensing window connected to the protective cavity is provided on the sensor protective cover at a position corresponding to the sensing area of ​​the sensor.

[0006] The sensor support is provided with a sensor mounting platform, and the sensor protective cover and the sensor mounting platform form a protective cavity. The sensor is set in the protective cavity and mounted on the sensor mounting platform.

[0007] An adjustment shim is detachably provided between the sensor mounting platform and the sensor, which can be used to adjust the mounting height of the sensor.

[0008] The sensor mounting platform is provided with a first mounting hole that runs vertically through the sensor. The adjusting shim is provided with a second mounting hole that runs vertically through the sensor. The sensor is provided with a mounting screw hole. One first mounting hole coaxially corresponds to one second mounting hole and one mounting screw hole. The shank of the mating mounting screw passes through the corresponding first mounting hole and the second mounting hole from bottom to top and is screwed into the mounting screw hole, thereby realizing the installation of the adjusting shim and the sensor on the sensor mounting platform.

[0009] The sensor support base has a connecting screw hole on its side, and the sensor protective cover has a connecting hole at a corresponding position on its side. The shank of the matching connecting screw passes through the connecting hole and is screwed into the corresponding connecting screw hole, thereby realizing the detachable installation of the sensor protective cover on the sensor support base.

[0010] The width of the sensing window in the vertical direction is greater than the width of the sensing area of ​​the sensor in the vertical direction.

[0011] Compared with the prior art, the advantages of this utility model are: (1) A protective cavity is formed by the detachable sensor protective cover and the sensor support base. The structure is simple, the installation is convenient, and the cost is low. (2) The sensor is placed in a protective cavity. The sensor cover can effectively isolate the dust, oil and other pollutants in the production site. At the same time, it can buffer mechanical vibration and impact to a certain extent, directly protect the sensor from physical damage and environmental interference, and ensure measurement accuracy and reliability. (3) A window corresponding to the sensor sensing area is set on the sensor protective cover. While achieving comprehensive physical protection, the sensor sensing function is not affected, thus balancing protection and functionality. The sensing probe on the sensor can extend out from the sensing window. Attached Figure Description

Figure 3 This is a second cross-sectional view of the present invention. Figure 4 This is an exploded structural diagram of the present invention. Detailed Implementation

[0013] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0014] As shown in the figure, a protective structure for a sensor includes a sensor 1 and a sensor support 2. The sensor 1 is mounted on the sensor support 2. A sensor protective cover 3 is detachably provided on the sensor support 2. A protective cavity 20 is formed between the sensor protective cover 3 and the sensor support 2. The sensor 1 is disposed in the protective cavity 20. A sensing window 31 is provided on the sensor protective cover 3 at the position corresponding to the sensing area 10 of the sensor 1 and communicating with the protective cavity 20. The sensing probe 11 on the sensor 1 can extend out from the sensing window 31. The sensor support 2 is detachably mounted on a corresponding tooling.

[0015] In this specific embodiment, a sensor mounting platform 21 is provided on the sensor support 2, and a protective cavity 20 is formed between the sensor protective cover 3 and the sensor mounting platform 21. The sensor 1 is placed inside the protective cavity 20 and mounted on the sensor mounting platform 21. By providing a dedicated sensor mounting platform 21, a stable and flat mounting reference surface is provided for the sensor 1, ensuring the stability of the installation and the accuracy of its position. The platform and the protective cover together constitute the protective cavity 20, with a clear and reasonable structure and superior protection.

[0016] In this specific embodiment, an adjusting shim 4 is detachably provided between the sensor mounting platform 21 and the sensor 1 for adjusting the mounting height of the sensor 1. The introduction of the detachable adjusting shim 4 enables flexible and precise fine-tuning of the sensor 1's mounting height. This structure is simple and reliable, adapting to different detection needs or compensating for installation errors without replacing the entire support base or sensor 1, greatly enhancing the versatility and adaptability of this protective structure.

[0017] In this specific embodiment, the sensor mounting platform 21 is provided with a first mounting hole 22 that extends vertically, the adjusting shim 4 is provided with a corresponding second mounting hole 41 that extends vertically, and the sensor 1 is provided with a corresponding mounting screw hole 12. Each first mounting hole 22 coaxially corresponds to one second mounting hole 41 and one mounting screw hole 12. The shank of the mating mounting screw 5 passes through the corresponding first mounting hole 22 and second mounting hole 41 sequentially from bottom to top and is screwed into the mounting screw hole 12, thus achieving the installation of the adjusting shim 4 and the sensor 1 on the sensor mounting platform 21. The structure is simple, installation and disassembly are convenient, and synchronous fixed connection of the three components is achieved.

[0018] In this specific embodiment, the sensor support 2 has a connecting screw hole 23 on its side, and the sensor protective cover 3 has a corresponding connecting hole 32 on its side. The connecting screw 6, with its shank passing through the connecting hole 32, is screwed into the corresponding connecting screw hole 23, enabling the sensor protective cover 3 to be detachably installed on the sensor support 2. This side-mounted screw connection method for detachable installation of the protective cover is simple in structure and reliable in connection. Disassembly is simple; just loosen the side screws to remove the protective cover, facilitating quick cleaning, maintenance, or replacement of the sensor 1, making the operation extremely convenient.

[0019] In this specific embodiment, the width of the sensing window 31 in the vertical direction is greater than the width of the sensing area 10 of the sensor 1 in the vertical direction. This effectively avoids the risk that the sensing area 10 may be blocked by the protective cover due to slight deviations in the installation position of the sensor 1 or after height adjustment, ensuring the reliability of the sensing function and reducing the installation accuracy requirements.
