Description

Technical Field

[0001] The utility model relates to the technical field of pressure sensors, in particular to a packaging structure of a ceramic pressure sensor. Background Art

[0002] Pressure sensor is the most commonly used sensor in industrial practice. It has excellent characteristics such as simple structure, small size, light weight and long service life. It has been widely used in aircraft, automobiles, ships, bridges and other fields. With the development of the times, there are more and more types of pressure sensors, among which ceramic pressure sensors are particularly widely used.

[0003] In the prior art, a packaging structure of a ceramic pressure sensor is proposed in a Chinese patent document with announcement number CN211121701U, wherein one end of the connector is provided with a pressure port at a middle position, a foam pad is provided on the outside of the pressure port inside the insulation layer, and a conical gap is provided between the insulation layer and the foam pad, a heat dissipation mechanism is fixed below the signal processing board, and an output line is connected to the middle position below the signal processing board. The utility model forms a conical gap between the insulation layer and the foam cushion layer. When the volume of the liquid freezes gradually increases, the foam cushion layer is squeezed toward the conical gap, so that the liquid tends to expand in the horizontal direction, thereby avoiding the squeezing of the diaphragm by the vertical expansion of the liquid when it freezes. By adding a heat dissipation mechanism on the rear side of the signal processing board, the pressure sensor in continuous operation can be dissipated in time. However, consistent with the traditional method, the above technical solution adjusts the internal structure of the device so that the device can adapt to temperature changes, but it can only be used for pressure sensors of one size, is not universal, and has poor practicality.

[0025] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with specific embodiments.

[0027] like Figures 1 to 4As shown, a packaging structure of a ceramic pressure sensor includes a packaging structure body 1, a support tray 2 and a driving gear 8, a telescopic rod 13 is provided on one side of the support tray 2, a transmission rod 5 is also provided on one side of the support tray 2, a positioning column 12 is provided inside the transmission rod 5, a threaded rod 11 is sleeved on one side of the transmission rod 5, a driving gear 8 is provided at one end of the threaded rod 11, a bracket 4 is provided below the support tray 2, a driven gear 7 is provided on the outer side of the telescopic rod 13, five through grooves are opened inside the driven gear 7, limit blocks 9 are provided at the through groove positions inside the driven gear 7, a cross bar 6 is provided at one end of the limit block 9, and a clamping plate 3 is provided at the other end of the cross bar 6. By providing the coordination of gears and power components, the device only needs to place the pressure sensor into the packaging structure and press down hard during use to complete the installation of the pressure sensor. It can be applied to ceramic sensors of various sizes, making it easier to use and more applicable, thereby enhancing the practicality of the device. During use, the ceramic pressure sensor is placed on top of the supporting tray 2 and then pressed. The pressure will act on the positioning column 12 through the transmission rod 5, thereby driving the threaded rod 11 to rotate, driving the driving gear 8 to rotate, and thus driving the driven gear 7 to rotate. The rotation of the driven gear 7 drives the limit block 9 to rotate, and then the clamping plate 3 is pulled through the cross bar 6, so that the device clamps the ceramic pressure sensor. The open annular design makes the device applicable to sensors of various sizes.

[0028] Further, such as Figure 4 As shown, a fixing block 10 is provided on the side of the bracket 4 away from the supporting tray 2, and the transmission rod 5 passes through the bracket 4 and is connected to the driving gear 8. The setting of the fixing block 10 makes the bracket 4 more stable, which helps to reduce the swaying and vibration of the sensor during operation and improves the stability of the entire system. The transmission rod 5 directly passes through the bracket 4 and is connected to the driving gear 8. Such a design can reduce transmission loss and improve the transmission efficiency and response speed of the sensor. During use, the fixing block 10 is fixed to the packaging structure body 1, and the linear force applied by the transmission rod 5 is used to apply a rotational force to the driving gear 8.

[0029] Further, such as Figure 4 As shown, the driven gear 7 and the driving gear 8 are in contact with each other and are meshingly connected. The driven gear 7 and the driving gear 8 are meshingly connected, which can effectively transmit force, improve the transmission efficiency of the sensor, and reduce energy loss. The driven gear 7 and the driving gear 8 are in direct contact and meshing connection, which can share the pressure in the transmission process, reduce the wear of parts, and extend the service life of the sensor. During use, the rotation of the driving gear 8 directly drives the driven gear 7 to rotate, thereby completing the transmission of kinetic energy and improving the practicality of the device.

[0030] Further, such as Figure 3As shown, the positioning column 12 is cylindrical in shape, and one end is fixed inside the transmission rod 5. The diameter of the positioning column 12 is consistent with the thread groove size of the threaded rod 11. The thread grooves of the positioning column 12 and the threaded rod 11 of the same size can make the engagement between each other more tight, thereby completing the transmission of kinetic energy and improving the practicality of the device. During use, the linear pressure applied by the transmission rod 5 will be transmitted to the threaded rod 11 through the positioning column 12, thereby driving the driven gear 7 to rotate.

[0031] Further, such as Figure 4 As shown, there are five through slots inside the driven gear 7, and the five through slots are in an arc-shaped structure deflected to one side. The arc-shaped structure deflected to one side can better allow the five cross bars 6 to move a consistent amount on the driven gear 7, so that the splint 3 can be expanded and merged, thereby improving the practicality of the device. During use, the limit block 9 will slide inside the through slot to complete the limited action.

[0032] Further, such as Figure 4 As shown, the bracket 4 is designed in the shape of a five-pointed star, and a sliding groove for the cross bar 6 to slide is opened inside the bracket 4. Such a design can make the bracket 4 more stable, and at the same time, it also provides sufficient activity space for the cross bar 6, avoiding basic functional exclusion and improving the practicality of the device.

[0033] Further, such as Figure 1 As shown, the packaging structure body 1 and the bracket 4 are connected and fixed by a fixing block 10. The fixed connection installation method makes the bracket 4 and the packaging structure body 1 more stable, avoids the limitation of function realization due to the unstable position during use, prolongs the service life of the device, and improves the practicality of the device.

[0034] Further, such as Figure 1 As shown, the splint 3 can be made of ferrite material, which has high electromagnetic shielding performance. By providing the splint 3 with ferrite material, the device can better shield electromagnetic interference that is unfavorable to the pressure sensor during use, enhance the accuracy of the pressure data collected by the device, and further enhance the practicality of the device.

[0035] Further, such as Figure 1 As shown, a connector for connecting the pressure sensor is provided inside the tray 2 (not shown in the figure). The connector is provided so that the signal collected by the ceramic pressure sensor is converted into data and transmitted in a timely manner, thereby improving the practicality of the device. During use, the packaging structure can be improved through the provided connector to form a signal path.
