Abstract
Description
Technical Field
[0001] This utility model relates to the field of sensor mounting isolation structure technology, and in particular to a stress-strain isolation structure and a sensing module thereof. Background Technology
[0002] Sensors are a type of commonly used electronic device used to convert changes in other physical quantities into changes in electrical characteristics, such as force sensors, optical sensors, and acoustic sensors.
[0003] While these sensors can detect specific changes in desired information, they are also susceptible to interference from other factors, especially in practical applications. Among these, stress and strain significantly affect sensor performance. Force sensors may output unwanted detection signals directly due to stress and strain; optical sensors may have their output signals affected by deformation caused by stress and strain; and many other sensors suffer from performance degradation due to internal structural deformation caused by stress and strain. Utility Model Content
[0004] To address the issue that stress and strain can easily affect sensor detection signals, this invention proposes a stress-strain isolation structure.
[0005] The technical solution adopted by this utility model is a stress-strain isolation structure, including a main body with a mounting groove, an isolation part disposed in the mounting groove and not in contact with the main body, and the isolation part is connected to the main body only through a connecting part, which connects a portion of the circumferential area of the isolation part.
[0006] Preferably, the mounting slot is a through hole or a blind hole.
[0007] Preferably, the main body, connecting part, and isolation part are located in the same plane.
[0008] Preferably, the shapes of the isolation part and the connecting part are the same as the shape of the mounting groove.
[0009] Preferably, the distances between the isolation section and the connecting section and the main body section are the same.
[0010] Preferably, the connecting part is a strip structure, with one end of the strip structure connected to the main body and the other end connected to the isolation part.
[0011] Preferably, there are at least two mounting slots, and each mounting slot has an isolation part and a connecting part.
[0012] Preferably, the main body, connecting part and isolation part are integrally formed.
[0013] Preferably, a detachable part is provided between the main body and the isolation part. When the isolation part is not in the isolation state, the detachable part is connected to the main body and the isolation part respectively. When the isolation part is in the isolation state, the isolation part is connected to the main body only through the connecting part.
[0014] To address the shortcomings of sensors that are susceptible to stress and strain, this invention proposes a sensing module.
[0015] The technical solution adopted in this utility model is a sensing module, which includes the stress-strain isolation structure described above.
[0016] Compared with the prior art, the present invention has the following beneficial effects:
[0017] This application discloses a stress-strain isolation structure. The main body has a mounting groove, in which an isolation part is placed. Components to be isolated are placed on the isolation part, which does not contact the main body. When the main body is subjected to force, stress and strain are generated. Since the isolation part is only connected to the main body through a connecting part, and the connecting part only connects a portion of the circumferential area of the isolation part, the stress and strain generated in the main body at this time can hardly be transmitted to the isolation part.
[0018] Compared with the prior art, the stress-strain isolation structure disclosed in this application can achieve the purpose of preventing stress and strain from affecting the element to be isolated.
[0019] This application also discloses a sensing module including the aforementioned stress-strain isolation structure. By setting up the stress-strain isolation structure, stress and strain can prevent them from affecting the detection signal of the sensing module, avoiding crosstalk between different modules and achieving higher sensing accuracy during use. Attached Figure Description
[0020] The present invention will now be described in detail with reference to the embodiments and accompanying drawings, wherein:
[0021] Figure 1 A schematic diagram of a stress-strain isolation structure provided according to an embodiment of the present invention is shown.
[0022] Label Explanation:
[0023] 10. Main body; 11. Mounting slot; 20. Isolation part; 30. Connecting part. Detailed Implementation
[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. Examples of embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar components or components 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.
[0025] This utility model discloses a stress-strain isolation structure. Please refer to [reference needed]. Figure 1 It includes a main body 10 with a mounting groove 11, an isolation part 20 disposed in the mounting groove 11 and not in contact with the main body 10, and the isolation part 20 is connected to the main body 10 only through a connecting part 30, which connects a portion of the circumferential area of the isolation part 20.
[0026] The main body 10 has a mounting groove 11, in which an isolation part 20 is placed. The component to be isolated is placed on the isolation part 20, which does not contact the main body 10. When the main body 10 is subjected to force, stress and strain are generated. Since the isolation part 20 is only connected to the main body 10 through a connecting part 30, and the connecting part 30 only connects a portion of the circumferential area of the isolation part 20, the stress and strain generated in the main body 10 at this time can hardly be transmitted to the isolation part 20. Compared with the prior art, the stress and strain isolation structure disclosed in this application can achieve the purpose of preventing stress and strain from affecting the component to be isolated.
[0027] Specifically, the connection between the isolation part 20 and the main body 10 is relatively weak, so the stress and strain that appear on the main body 10 cannot have a significant impact on the isolation part 20. As the area connected by the connecting part 30 on the isolation part 20 shrinks, a better isolation effect can be obtained, so that the stress and strain generated by the main body 10 are hardly transmitted to the isolation part 20.
[0028] It should be noted that the shape of the isolation part 20 is not limited. Preferably, the shape and size of the isolation part 20 are the same as the shape and size of the element to be isolated, so that the overall structure of the stress-strain isolation structure is more compact, and other elements that need to be installed can be provided to the maximum extent in positions other than the mounting groove 11 of the main body 10.
[0029] In some embodiments, please refer to Figure 1 The mounting slot 11 is a through hole or a blind hole.
[0030] Specifically, the mounting groove 11 in this application can be either a through hole or a blind hole, depending on the specific application. When the mounting groove 11 is a blind hole, the connecting part 30 can be located at the bottom of the mounting groove 11 to connect a portion of the circumferential area of the isolation part 20, thus further optimizing the surface dimensions of the stress-strain isolation structure. Obviously, the connecting part 30 can also be located on the side wall of the mounting groove 11. When the mounting groove 11 is a through hole, the connecting part 30 can only be located on the side wall of the mounting groove 11 to connect a portion of the circumferential area of the isolation part 20, allowing for a thinner and lighter stress-strain isolation structure, and simplifying the manufacturing process.
[0031] In some embodiments, please refer to Figure 1 The main body 10, the connecting part 30 and the isolation part 20 are located in the same plane.
[0032] It should be noted that the main body 10, connecting part 30, and isolation part 20 are located in the same plane. Because the isolation part 20 needs to achieve a good isolation effect, the area where the connecting part 30 and the isolation part 20 are connected in the circumferential direction is often very small, making it extremely susceptible to damage under external impact and compression. For these reasons, the main body 10, connecting part 30, and isolation part 20 are located in the same plane, and the isolation part 20 is located within the mounting groove 11 of the main body 10. The isolation part 20 does not protrude outwards, and other external structures are unlikely to directly collide or contact with the isolation part 20, thus protecting it and preventing damage to the stress-strain isolation structure.
[0033] In some specific embodiments, please refer to Figure 1 The shapes of the isolation part 20 and the connecting part 30 are the same as the shape of the mounting groove 11.
[0034] Specifically, the shapes of the isolation part 20 and the connecting part 30 are the same as those of the mounting groove 11, so as to ensure the isolation effect of the isolation part 20 while maintaining the structural strength of the main body 10 to the greatest extent, making the stress-strain isolation structure less prone to bending as a whole.
[0035] In some more specific embodiments, please refer to Figure 1 The distances between the isolation section 20 and the connecting section 30 and the main body section 10 are the same.
[0036] Specifically, in order to further improve the isolation effect of the isolation section 20, and to make the isolation section 20 more uniformly affected even under small stress and strain, noise parameters are introduced at the calculation level to eliminate noise from small stress and strain.
[0037] In some embodiments, please refer to Figure 1The connecting part 30 is a strip structure, with one end of the strip structure connected to the main body part 10 and the other end connected to the isolation part 20.
[0038] It should be noted that the connecting part 30 is a strip structure. Compared with other structures, the strip structure receives less stress and strain at one end of the isolation part 20, thereby further improving the stress and strain isolation effect of the stress and strain isolation structure.
[0039] In some embodiments, please refer to Figure 1 The mounting slot 11 has at least two slots, and each mounting slot 11 has an isolation part 20 and a connecting part 30.
[0040] Specifically, the mounting slot 11 has at least two slots, allowing the stress-strain isolation structure to accommodate multiple elements to be isolated, thus expanding its application scenarios. Alternatively, the stress-strain isolation structure can be further processed to obtain a stress-strain isolation structure with a single mounting slot 11.
[0041] In some embodiments, the main body 10, the connecting part 30, and the isolation part 20 are integrally formed.
[0042] To facilitate processing, improve structural strength, and extend service life, the main body 10, connecting part 30, and isolation part 20 are integrally formed.
[0043] In some embodiments, a detachable portion is provided between the main body 10 and the isolation portion 20. When the isolation portion 20 is not in an isolated state, the detachable portion is connected to the main body 10 and the isolation portion 20 respectively. When the isolation portion 20 is in an isolated state, the isolation portion 20 is connected to the main body 10 only through the connecting portion 30.
[0044] Specifically, when the stress-strain isolation structure is not in use, there is a detachable part between the main body 10 and the isolation part 20. When it is not necessary to install the isolation element on the stress-strain isolation structure, it can be used as a normal structural component. In this case, the detachable part connects the main body 10 and the isolation part 20, thereby achieving high structural strength. When it is necessary to install the isolation element on the stress-strain isolation structure, the detachable part can be removed, so that the isolation part 20 is connected to the main body 10 only through the connecting part 30 to achieve the isolation effect. It should be noted that the detachable part can be for single use, that is, it can be reinstalled after being removed, or it can be a structure that can be used multiple times. In this case, multiple mounting slots 11 can also be provided on the main body 10.
[0045] This utility model also discloses a sensing module, including the stress-strain isolation structure described above.
[0046] By setting up a stress-strain isolation structure, stress and strain can prevent them from affecting the detection signal of the sensing module, avoiding crosstalk between different modules and achieving higher sensing accuracy during use.
