Description

Technical Field

[0001] This utility model relates to an integrated component installation device with buffering performance, which is mainly used to connect and install a vibration and impact source to a corresponding installation structure to form a connection and installation of the vibration and impact source, thereby reducing the amount of vibration and impact on the installation structure during operation. Background Technology

[0002] Equipment used in special environments, such as spacecraft, is typically equipped with numerous precision sensors or data acquisition instruments to facilitate normal operation and data collection. To meet the deployment requirements of spacecraft components, the mounting structures containing these sensors or instruments often include pyrotechnic separation devices (vibration and shock sources). While pyrotechnic separation devices are technologically mature, the explosion of gunpowder generates high-frequency, high-amplitude impacts, which can reach over 10,000g, potentially causing malfunctions in precision instruments.

[0003] To ensure the stable installation of pyrotechnic separation devices and reduce the impact of the shock wave generated by their explosion on nearby precision sensors and data acquisition instruments, buffering devices for pyrotechnic separation device installation have begun to be used. Existing buffering device installation equipment generally includes a mounting base and energy-absorbing devices evenly distributed on the mounting base. The blast shock wave is partially absorbed as it passes through the location of the energy-absorbing device, thus achieving a damping effect. However, because the blast shock wave travels at a high speed through the mounting base, and the contact area between the energy-absorbing device and the blast shock wave is relatively small, the overall contact rate between the energy-absorbing device and the blast shock wave is relatively low, resulting in a relatively weak damping effect of existing buffering device installation equipment.

[0004] Therefore, the research objective of this utility model is to design an integrated component mounting device with buffering performance that can effectively improve the overall contact rate between the energy absorption device and the explosion shock wave, thereby significantly improving the vibration reduction and shock reduction effect. Summary of the Invention

[0005] In view of the technical problems existing in the prior art, the present invention provides an integrated component mounting device with buffering performance, which can effectively solve the technical problems existing in the prior art.

[0006] The technical solution of this utility model is: A device for mounting an integrated component with cushioning properties, comprising: A cylindrical base is provided with corresponding mounting planes at both ends and a corresponding buffer and vibration damping area in the middle. The wall thickness of the buffer and vibration damping area is greater than the wall thickness on both sides of the cylindrical base, and the buffer and vibration damping area is provided with at least two rows of corresponding vibration damping holes evenly distributed at intervals, with adjacent rows of vibration damping holes being staggered. The energy absorption device includes a damping housing fixedly embedded in the damping hole, and the damping housing is filled with a number of corresponding damping particles for damping.

[0007] The cross-section of the vibration damping hole is circular, and there are three rows of vibration damping holes. The vibration damping holes in adjacent rows are staggered. The vibration damping housing of the energy absorption device is fixedly assembled into the vibration damping hole by screw connection.

[0008] A particle filling hole is provided on one side of the vibration damping housing, and a corresponding sealing cover is fixedly installed at the particle filling hole. At least one corresponding pressure relief hole is provided at the position of the vibration damping housing where the particle filling hole is not provided.

[0009] A corresponding boss is fixed to the vibration damping housing. At least one set of locking planes for limiting the turning parts are provided around the boss, and the locking planes of the boss are located on the outside of the closed cover.

[0010] A corresponding washer is detachably installed on the side of the boss facing the cylindrical base. The outer side of the washer is set as a flat surface adapted to the boss, and the inner side of the washer is set as an arc surface adapted to the side wall of the cylindrical base.

[0011] The gasket is made of aluminum alloy.

[0012] The cylindrical base has corresponding locking holes on its mounting surfaces at both ends.

[0013] Alternatively, the cross-section of the vibration damping hole is square, there are two rows of vibration damping holes, the two rows of vibration damping holes are staggered, and the vibration damping housing of the energy absorption device is fixedly assembled into the vibration damping hole by interference fit.

[0014] Alternatively, the cross-section of the vibration damping hole is convex, and there are two rows of vibration damping holes. The two rows of vibration damping holes are staggered, and the ends of the vibration damping holes with smaller cross-sectional widths are opposite each other. The vibration damping housing of the energy absorption device is fixedly assembled into the vibration damping hole by interference fit.

[0015] Compared with the prior art, the advantages and positive effects of this utility model are as follows: 1) The present invention provides a corresponding buffer and vibration damping area in the middle of the cylindrical base. The wall thickness of the buffer and vibration damping area is greater than the wall thickness on both sides of the cylindrical base. The buffer and vibration damping area is provided with at least two rows of corresponding vibration damping holes at intervals. The adjacent two rows of vibration damping holes are staggered. Then, the energy absorption device is fixedly embedded in the staggered vibration damping holes.

[0016] The increased wall thickness of the buffer damping zone overcomes the structural strength deficiency of the cylindrical base caused by the damping holes. Simultaneously, the increased wall thickness expands the contact area between the energy-absorbing device and the cylindrical base, allowing the explosive shock wave to disperse to a certain extent as it passes through the buffer damping zone, thus slowing its transmission rate. This effectively increases the overall contact rate between the energy-absorbing device and the explosive shock wave, enabling the invention to maintain overall structural strength while significantly improving vibration damping and shock reduction.

[0017] 2) A particle filling hole is provided on one side of the vibration damping housing of this utility model to facilitate the rapid filling of damping particles for vibration damping; a corresponding sealing cover is fixedly installed at the particle filling hole, and at least one corresponding pressure relief hole is provided at the position of the vibration damping housing where there is no particle filling hole. By setting the pressure relief hole, the sealing cover can be stably installed at the particle filling hole of the vibration damping housing to ensure the practical effect of this utility model.

[0018] 3) A corresponding boss is fixedly connected to the vibration damping housing of this utility model. At least one set of locking planes for limiting the screwing component is provided at the periphery of the boss. The locking planes of the boss are located on the outside of the closed cover, so that the screwing component can be limited by the locking plane of the boss while making room with the closed cover, so as to facilitate the quick screwing and installation of the energy absorption device.

[0019] 4) A corresponding washer can be detachably installed on the side of the boss facing the cylindrical base of this utility model. The outer side of the washer is set as a flat surface that matches the boss, and the inner side is set as an arc surface that matches the side wall of the cylindrical base. By using a non-standard washer, the boss and the cylindrical base can be properly connected, thereby avoiding point contact between the energy absorption device and the arc surface of the cylindrical base, which would lead to stress concentration, and further improving the practical effect of this utility model.

[0020] 5) The vibration damping holes of this utility model have a square cross-section and are arranged in two rows, staggered. The vibration damping housing of the energy absorption device is fixedly assembled into the vibration damping holes by an interference fit. Characteristic shock waves are mostly compression waves (P-waves), with wavelength λ = sound velocity v / frequency f. The lower the frequency, the longer the wavelength. Characteristic shock waves are mainly low-frequency. Therefore, by setting the vibration damping holes in a square shape, the axial length of the vibration damping housing on the cylindrical base can be extended under the premise of the same filling amount, thereby better reducing the transmission of shock waves and thus reducing the impact response at the output end. Testing showed that the buffering effect of the integrated component mounting device with a square cross-section for the vibration damping holes achieved 64.5%.

[0021] 6) The vibration damping holes of this invention have a convex cross-section, with two rows of holes staggered and positioned opposite each other with the smaller cross-sectional width of the holes. The vibration damping housing of the energy absorption device is fixedly assembled into the vibration damping holes via an interference fit. Under the same filling amount, the convex cross-section of the vibration damping holes can further extend the axial length of the vibration damping housing on the cylindrical base, thereby better reducing the transmission of shock waves. Testing showed that the buffering effect of the integrated component mounting device with a convex cross-section of the vibration damping holes achieved 67.2%. Attached Figure Description

Detailed Implementation

[0032] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0033] Example 1: refer to Figure 1-4 A device for mounting an integrated component with cushioning properties, comprising: A cylindrical base 1 has corresponding mounting planes 101 at both ends and a corresponding buffer and vibration damping area 102 in the middle. The wall thickness of the buffer and vibration damping area 102 is greater than the wall thickness on both sides of the cylindrical base 1, and the buffer and vibration damping area 102 is provided with at least two rows of corresponding vibration damping holes 103 at intervals. The adjacent rows of vibration damping holes 103 are staggered. The energy absorption device 2 includes a damping housing 201 fixedly embedded in the damping hole 103, and the damping housing 201 is filled with a number of corresponding damping particles 202.

[0034] The increased wall thickness of the buffer damping zone 102 overcomes the structural strength deficiency of the cylindrical base 1 caused by the installation of the damping holes 103. At the same time, the increased wall thickness of the buffer damping zone 102 expands the contact area between the energy absorption device 2 and the cylindrical base 1, and enables the explosive shock wave to be dispersed to a certain extent when it passes through the buffer damping zone 102, thereby slowing down its transmission rate. In this way, the overall contact rate between the energy absorption device 2 and the explosive shock wave can be effectively improved, so that this utility model can effectively and significantly improve the vibration reduction and shock reduction effect while maintaining the overall structural strength.

[0035] The cross-section of the vibration damping hole 103 is circular. There are three rows of vibration damping holes 103, and the adjacent rows of vibration damping holes 103 are staggered. The vibration damping housing 201 of the energy absorption device 2 is fixedly assembled into the vibration damping hole 103 by screw connection.

[0036] A particle filling hole 2011 is provided on one side of the vibration damping housing 201 to facilitate the rapid filling of damping particles 202 for vibration damping. A corresponding sealing cover 203 is fixedly installed at the particle filling hole 2011. At least one corresponding pressure relief hole 2012 is provided at the position of the vibration damping housing 201 where the particle filling hole 2011 is not provided. The provision of the pressure relief hole 2012 enables the sealing cover 203 to be stably installed at the particle filling hole 2011 of the vibration damping housing 201, thereby ensuring the practical effect of this utility model.

[0037] A corresponding boss 3 is fixedly connected to the vibration damping housing 201. At least one set of locking planes 301 for limiting the screwing component is provided at the periphery of the boss 3. The locking planes of the boss 3 are located on the outside of the closed cover 203, so that the screwing component can be limited by the locking planes 301 of the boss 3 while making room with the closed cover 203, so as to facilitate the quick screwing and installation of the energy absorption device 2.

[0038] A corresponding washer 4 is detachably installed on the side of the boss 3 facing the cylindrical base 1. The outer surface of the washer 4 is set as a plane to fit the boss 3, and the inner surface of the washer 4 is set as an arc surface to fit the side wall of the cylindrical base 1. The washer 4 is made of aluminum alloy.

[0039] By using a non-standard washer 4, the boss 3 and the cylindrical base 1 are properly connected, thereby avoiding stress concentration caused by point contact between the energy absorption device 2 and the arc surface of the cylindrical base 1, and further improving the practical effect of this utility model.

[0040] The cylindrical base 1 has corresponding locking holes 5 on its mounting planes at both ends, so as to facilitate the locking operation between the pyrotechnic separation device and the cylindrical base 1 of this utility model, as well as between this utility model and the corresponding mounting structure.

[0041] Example 2: refer to Figure 5 The difference between this embodiment and embodiment one is that the cross-section of the vibration damping hole 103 is square, there are two rows of vibration damping holes 103, the two rows of vibration damping holes 103 are staggered, and the vibration damping housing 201 of the energy absorption device 2 is fixedly assembled into the vibration damping hole 103 by interference fit.

[0042] Characteristic shock waves are mostly compression waves (P-waves), with wavelength λ = sound speed v / frequency f. The lower the frequency, the longer the wavelength. Characteristic shock waves are mainly low-frequency. Therefore, by setting the vibration damping hole 103 in a square shape, the length of the vibration damping shell 201 in the axial direction of the cylindrical base 1 can be extended under the premise of the same filling amount, thereby better reducing the transmission of shock waves and thus reducing the impact response at the output end.

[0043] It should be noted that this embodiment is implemented in the same way as embodiment one in terms of principle and technical effect. For the sake of brevity, any parts not mentioned in this embodiment can be referred to the corresponding content in embodiment one.

[0044] Example 3: refer to Figure 6 The difference between this embodiment and embodiment one is that the cross-section of the vibration damping hole 103 is convex, there are two rows of vibration damping holes 103, the two rows of vibration damping holes 103 are staggered, and the ends of the vibration damping holes 103 with smaller cross-sectional widths are opposite each other. The vibration damping housing 201 of the energy absorption device 2 is fixedly assembled into the vibration damping hole 103 by interference fit.

[0045] Under the premise of the same filling amount, the convex cross-section of the damping hole 103 can further extend the length of the damping housing 201 in the axial direction of the cylindrical base 1, thereby better reducing the transmission of shock waves. It should be noted that the implementation principle and technical effect of this embodiment are the same as those of Embodiment 1. For the sake of brevity, any parts not mentioned in this embodiment can be referred to the corresponding content in Embodiment 1.

[0046] Firecracker impact buffer tests were conducted on the products of Examples 1 to 3 using a firecracker impact buffer test rig. Firecrackers were used as the impact source. Impact time-domain data of the lower flange of the base were collected during the test. Based on the experimental data, measurement points were selected to plot the impact response spectrum curves corresponding to the integrated component mounting devices with buffering performance in Examples 1 to 3. The impact response spectrum curve obtained after the firecracker impact buffer test on the product of Example 1 is shown below. Figure 7 As shown, the impact response spectrum curve obtained after the product of Example 2 underwent a firecracker-buffered impact test is shown in the figure. Figure 8 As shown, the impact response spectrum curve obtained after the product of Example 3 underwent a firecracker-buffered impact test is shown in the figure. Figure 9 As shown in Table 1, the impact attenuation effect was calculated and analyzed based on the impact response spectrum values ​​before and after the impact.

[0048] As shown in Table 1, Embodiments 1, 2, and 3 of this utility model have high buffering effects, and the buffering effect of Embodiment 3 is better than that of Embodiment 2, while the buffering effect of Embodiment 2 is better than that of Embodiment 1.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields.
