Description

Technical Field

[0001] The present invention relates to the technical field of sensors, and in particular to an isolation component of a sensor. Background Art

[0002] The core sensitive component of the quartz gyroscope is the angular velocity detector. At present, the angular velocity detector is usually fixed on the boss inside the gyroscope shell by bonding, so that the angular velocity detector and the gyroscope shell are in a rigid connection mode. However, since the angular velocity detector and the shell are made of different materials, there is a difference in their thermal expansion coefficients. When the external temperature changes, the bonding surface between the angular velocity detector and the shell will produce significant temperature stress, thereby affecting the working performance of the gyroscope. In addition, when the gyroscope encounters external vibration or impact, since the angular velocity detector and the gyroscope shell are rigidly connected, the external vibration and impact will be directly transmitted to the angular velocity detector, causing short-time pulse shock and high-frequency vibration, thereby weakening the performance and service life of the gyroscope.

[0031] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] like Figures 1 to 4 As shown, an embodiment of the present invention discloses an isolation component of a sensor, wherein the sensor includes a housing 1 , an isolation component 2 and an angular velocity detection component 3 .

[0033] The isolation component 2 is arranged in the inner cavity 11 of the shell 1 and is connected to the bottom surface of the inner cavity 11. A plurality of hollow holes 20 are provided on the isolation component 2. The isolation component 2 includes a hollow part 21. The hollow part 21 has a first surface and a second surface arranged relative to each other in a first direction. The first surface is arranged relative to the second surface and adjacent to the bottom surface of the inner cavity 11. A boss 210 is provided on the second surface. The boss 210 is suitable for setting the angular velocity detection component 3.

[0034] For example, in order to make the technical solution of the present application easier to understand, the following takes the first direction being consistent with the up-down direction as an example to further describe the technical solution of the present application, wherein the up-down direction is as follows: Figure 1 shown.

[0035] The isolation component 2 and the angular velocity detection component 3 are both installed in the housing 1, the isolation component 2 is arranged at the bottom of the inner cavity 11, and the angular velocity detection component 3 is arranged below the isolation component 2. The isolation component 2 provides a stress isolation layer between the angular velocity detection component 3 and the housing 1. When external vibration or impact changes occur, the isolation component 2 can resist deformation and damage under the action of external forces, reduce the impact of the change of the housing 1 on the angular velocity detection component 3, thereby ensuring the stability of the angular velocity detection component 3 and enhancing the vibration and impact resistance of the isolation component of the sensor.

[0036] The hollow part 21 has two oppositely arranged surfaces in the up and down directions, namely a first surface and a second surface. The first surface is arranged below the second surface. A boss 210 is designed on the second surface. The boss 210 is used to fix the angular velocity detection part 3 to ensure its position accuracy and stability during operation.

[0037] The isolation component 2 is designed with a plurality of hollow holes 20, which not only reduce the weight of the isolation component 2, and thus reduce the weight of the isolation component of the sensor, but also the hollow holes 20 can reduce the stress transmitted to the boss 210 by the hollow part 21 through thermal expansion. Specifically, in practical applications, when the ambient temperature changes, the thermal expansion coefficients of different materials are different, which will lead to stress accumulation between the materials. The presence of the hollow holes 20 provides more degrees of freedom for the thermal expansion of the material, so that the stress can be dispersed and released through the area around the hollow holes 20, rather than being concentrated and transmitted to the boss 210, thereby reducing the influence of the stress caused by temperature changes on the angular velocity detection component 3.

[0038] In addition, the design of the hollow hole 20 not only helps to disperse thermal stress, but also increases the flexibility of the isolation component 2, and absorbs and buffers external vibration and impact to a certain extent. When the external environment vibrates or impacts, the hollow hole 20 can provide a certain elastic deformation space, thereby reducing the direct impact of these external forces on the angular velocity detection member 3.

[0039] In the related art, the core sensitive component of the isolation component of the quartz sensor is the angular velocity detection component 3. At present, the angular velocity detection component 3 is usually fixed on the boss in the housing of the isolation component of the sensor by bonding, so that the angular velocity detection component 3 and the gyro tube shell are in a rigid connection mode. However, since the angular velocity detection component 3 and the housing are made of different materials, there is a difference in their thermal expansion coefficients. When the external temperature changes, the bonding surface between the angular velocity detection component 3 and the housing will produce significant temperature stress, thereby affecting the working performance of the isolation component of the sensor. In addition, when the isolation component of the sensor encounters external vibration or impact, since the angular velocity detection component 3 and the gyro tube shell are rigidly connected, the external vibration and impact will be directly transmitted to the angular velocity detection component 3, thereby causing short-time pulse impact and high-frequency vibration, thereby weakening the performance and service life of the isolation component of the sensor.

[0040] The isolation component of the sensor of the embodiment of the present invention effectively reduces the influence of external vibration and temperature change on the angular velocity detection component 3 by arranging the isolation component 2 between the housing of the sensor and the angular velocity detection component 3, and arranging the hollow hole 20 on the isolation component 2, so that the angular velocity detection component 3 can maintain high precision and high stability in various complex environments, thereby improving the performance of the sensor. In addition, the isolation component 2 is arranged in the inner cavity 11, and the hollow hole 20 is arranged on the isolation component 2, which reduces the weight of the sensor and realizes the lightweight of the sensor.

[0041] Optionally, the angular velocity detection element 3 includes a quartz tuning fork.

[0042] Optionally, the angular velocity detection member 3 is bonded to the boss 210 by an insulating adhesive. Thus, the insulating adhesive can not only fix the angular velocity detection member 3 on the boss 210, but also ensure the insulation between the angular velocity detection member 3 and the boss 210, thereby avoiding unnecessary signal interference.

[0043] In some embodiments, the material of the isolation component 2 is the same as that of the angular velocity detection component 3. Therefore, when the temperature of the environment in which the isolation component of the sensor is located changes, since the expansion coefficient of the material of the isolation component 2 is the same as that of the material of the angular velocity detection component 3, the thermal stress generated by the isolation component 2 and the angular velocity detection component 3 is similar, thereby effectively reducing the stress generated by the mismatch of thermal expansion coefficients of different materials, and reducing the risk of detection failure of the angular velocity detection component 3 due to the fracture of the connection between the boss 210 and the angular velocity detection component 3.

[0044] In some embodiments, the isolation assembly 2 includes a strip 22 extending along a second direction, the second direction being orthogonal to the first direction, and two strips 22 are spaced apart along a third direction, the third direction being orthogonal to both the second direction and the first direction.

[0045] The hollow piece 21 is arranged between the two strip pieces 22 .

[0046] For example, Figures 1 to 4 As shown, in order to make the technical solution of the present application easier to understand, the technical solution of the present application is further described below by taking the second direction being consistent with the left-right direction and the third direction being consistent with the front-back direction as an example, wherein the left-right direction and the front-back direction are as shown in FIG. Figure 1 shown.

[0047] The strip 22 extends in the left-right direction, and the two strips 22 are arranged at intervals in the front-back direction to form a frame structure. The hollow piece 21 is arranged in the middle part of this frame structure. With the support of the strip 22, the hollow piece 21 can be more firmly fixed in the inner cavity 11 of the shell 1. This design not only improves the structural rigidity and stability of the isolation component 2, but also enables it to effectively release stress when the temperature changes and external vibrations occur, and protects the angular velocity detection component 3 from damage. Moreover, the strip 22 can be used to evenly load and improve the carrying capacity of the isolation component 2. The hollow piece 21 and the isolation component work together to enable the isolation component 2 to maintain a good shape and function under external vibration and impact conditions, thereby effectively protecting the angular velocity detection component 3 from the influence of changes in the external environment, enhancing its anti-vibration and anti-impact performance, and ensuring the high precision and high stability of the isolation component of the sensor in various complex environments.

[0048] In some embodiments, the hollow piece 21 includes a central portion 211 , an annular portion 212 and a first connecting portion 213 .

[0049] The boss 210 is disposed on the central portion 211 , and a center line of the central portion 211 extends along a first direction.

[0050] The annular portion 212 is provided on the outer circumference side of the central portion 211 and is spaced apart from the central portion 211 .

[0051] The first connection portion 213 is used to connect the central portion 211 and the annular portion 212 . A plurality of first connection portions 213 are provided. The plurality of first connection portions 213 are arranged at intervals around the center line of the central portion 211 , and the interval between two adjacent first connection portions 213 forms a first hollow hole 201 .

[0052] For example, Figure 2 and Figure 3 As shown, the central portion 211 is generally flat, and the center line of the central portion 211 is consistent with the up and down direction. The boss 210 above the central portion 211 is used to fix the angular velocity detection member 3, and the annular portion 212 surrounds the central portion 211 to provide additional structural support and stability. A plurality of first connecting portions 213 connect the central portion 211 and the annular portion 212, which not only provide the necessary structural strength, but also form a plurality of first hollow holes 201 between the central portion 211 and the annular portion 212. These first hollow holes 201 not only reduce the weight of the hollow member 21, but also provide additional space for thermal expansion and stress release of the material, effectively reduce the stress caused by temperature changes and external vibrations, and protect the stability and reliability of the angular velocity detection member 3. Through this design, the hollow member 21 achieves lightweight and stress optimization while ensuring structural strength, further improving the performance and environmental adaptability of the isolation component of the sensor.

[0053] In some embodiments, the hollow piece 21 includes a second connection portion 214, and a plurality of second connection portions 214 are arranged at intervals on the outer peripheral side of the annular portion 212 around the center line of the central portion 211, one end of each second connection portion 214 is connected to the strip piece 22, and the other end of each second connection portion 214 is connected to the annular portion 212, and the interval between two adjacent second connection portions 214 connected to the same strip piece 22 forms a second hollow hole 202.

[0054] For example, Figure 4 As shown, there are four second connection parts 214, two of which are arranged at the front end of the annular part 212 and connected to the same strip 22, and the interval between the two second connection parts 214 is the second hollow hole 202. The other two second connection parts 214 are arranged at the rear end of the annular part 212 and connected to the same strip 22, and the interval between the two second connection parts 214 is the second hollow hole 202.

[0055] It is understandable that the number of the second connection parts 214 can also be 6, 8, etc.

[0056] The isolation component of the sensor of the embodiment of the present invention, by providing the first hollow hole 201 and the second hollow hole 202, not only reduces the weight of the hollow component 21, but also provides additional space for thermal expansion and stress release of the material, effectively reduces the stress caused by temperature changes and external vibrations, and protects the stability and reliability of the angular velocity detection component 3. Through this multi-level design, the hollow component 21 achieves lightweight and stress optimization while ensuring structural strength and stability, further improving the overall performance and environmental adaptability of the isolation component of the sensor.

[0057] In some embodiments, the hollow pieces 21 are arranged symmetrically with respect to the first plane, and the first plane is a plane formed by the intersection of the first direction and the third direction.

[0058] For example, Figure 4 As shown, the first plane is a plane formed by the intersection of the up-down direction and the front-back direction. The hollow piece 21 is arranged symmetrically relative to the first plane, in other words, the left half and the right half of the hollow piece 21 are arranged symmetrically.

[0059] The hollow part 21 is designed as a symmetrical structure, which ensures that stress is evenly distributed in all directions. When external environmental stress (such as temperature change, vibration or impact) acts on the hollow part 21, the symmetrical structure can evenly distribute these stresses throughout the structure instead of concentrating them at a certain point or area. This uniform stress distribution helps to reduce local stress concentration, thereby reducing the risk of deformation of the boss 210, thereby ensuring the stability of the angular velocity detection part 3, and further enhancing its anti-vibration and anti-impact performance.

[0060] In some embodiments, the isolation assembly 2 includes a reinforcement block 23 , the reinforcement block 23 and the hollow member 21 are spaced apart in the second direction, and the two ends of the reinforcement block 23 in the third direction are fixedly connected to the two strip members 22 .

[0061] For example, Figure 4 As shown, the reinforcing block 23 is arranged on the right side of the hollow member 21, and the front end and the rear end of the reinforcing block 23 are respectively connected to a strip member 22. The reinforcing block 23 improves the overall structural strength of the isolation assembly 2, thereby helping to enhance the stability of the isolation assembly 2, so that it is not easy to deform or damage when subjected to external vibration or impact.

[0062] In some embodiments, in the first direction, the size of the strip member 22 is larger than the size of the hollow member 21, and the size of the strip member 22 is larger than the size of the reinforcement block 23, the hollow member 21 and the reinforcement block 23 are arranged at intervals from the bottom surface of the inner cavity 11, and each strip member 22 is provided with a support portion 221 on one side of the bottom surface of the inner cavity 11, and the support portion 221 is connected to the bottom wall of the inner cavity 11.

[0063] For example, Figure 2 As shown, in the up-down direction, the size of the strip member 22 is larger than the size of the hollow member 21 , and the size of the strip member 22 is larger than the size of the reinforcing block 23 .

[0064] The bottom surfaces of the hollow member 21 and the reinforcing block 23 are spaced apart from the bottom surface of the inner cavity 11 . A supporting portion 221 is provided at the lower end of the strip member 22 . The lower end of the supporting portion 221 is connected to the bottom surface of the inner cavity 11 , thereby supporting the entire isolation assembly 2 .

[0065] Therefore, a certain gap is left between the bottom surface of the hollow piece 21 and the reinforcing block 23 and the bottom surface of the inner cavity 11, avoiding direct contact. This design helps to reduce the external vibration directly transmitted to the hollow piece 21 and the reinforcing block 23 through the bottom surface of the inner cavity 11, thereby protecting the stability of the angular velocity detection member 3.

[0066] Optionally, the hollow piece 21 , the strip piece 22 and the reinforcement block 23 are integrally formed, or the hollow piece 21 , the strip piece 22 and the reinforcement block 23 are connected by bonding to form the isolation assembly 2 .

[0067] In some embodiments, each strip 22 is provided with a plurality of conductive sheets 222, and the conductive sheets 222 are arranged adjacent to the hollow piece 21 relative to the reinforcing block 23. The isolation component of the sensor includes a detection module, and the conductive sheets 222 are used to electrically connect the angular velocity detection element 3 with the detection module.

[0068] For example, Figure 1 As shown, the angular velocity detection member 3 is connected to the conductive sheet 222 through an internal circuit, and the conductive sheet 222 is connected to the detection module through other internal circuits, thereby realizing the transmission of the detection signal of the angular velocity detection member 3. The multiple conductive sheets 222 arranged on each strip 22 are distributed in specific areas of the strip 22, and these areas are adjacent to the hollow member 21, ensuring the close connection between the conductive sheet 222 and the angular velocity detection member 3. This layout design not only simplifies the internal electrical wiring, but also reduces the length of the signal transmission path, thereby improving the efficiency and reliability of signal transmission.

[0069] In some embodiments, a shielding electrode (not shown in the figure) is provided on the first surface of the hollow member 21. The shielding electrode is suitable for grounding connection. The shielding electrode is a gold-plated layer and is used to isolate electromagnetic interference signals.

[0070] For example, the first surface of the hollow member 21 is the lower surface of the hollow member 21 or the bottom surface of the hollow member 21. Since the detection signal of the angular velocity detection member 3 is very weak, it is easily affected by external electromagnetic interference. The shielding electrode is connected to the ground to effectively block and absorb external electromagnetic interference, protect the detection signal of the angular velocity detection member 3 from interference, and ensure the purity and reliability of the signal.

[0071] In some embodiments, the isolation assembly of the sensor further includes a cover plate 4, which is welded to the housing 1 to seal the inner cavity 11. For example, the inner cavity 11 of the housing 1 can be sealed by the cover plate 4, thereby protecting the internal angular velocity detector 3, the isolation assembly 2, etc. from the influence of the external environment.

[0072] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
