Description

Technical Field

[0001] This application relates to the field of aerospace technology, and more specifically, to a camera vibration damping support unit and a camera vibration damping support assembly. Background Technology

[0002] With the development of aerospace remote sensing technology, remote sensing cameras are becoming increasingly common. As camera resolution improves, the requirements for camera installation conditions also become more stringent. Currently, as cameras become more complex, their tolerance to vibration environments is gradually decreasing. The field widely uses bipod flexible supports to reduce the impact of launch vibration on the camera. Bipod flexible supports typically employ an inner and outer sleeve design, with one sleeve connecting to the camera and the other to the external mounting position. An injection hole is provided on the outer sleeve, through which damping adhesive is injected between the inner and outer sleeves. In launch vibration environments, the damping adhesive suppresses vibrations transmitted from the external mounting position to the camera, thereby reducing the impact of vibration on the camera. However, bipod flexible supports produced using this method of injecting damping adhesive between the inner and outer sleeves through the injection hole require the damping adhesive to dry completely before use, resulting in a longer production cycle. Summary of the Invention

[0003] The purpose of this application is to provide a camera vibration damping support unit and a camera vibration damping support assembly to address at least one of the technical problems mentioned in the background art.

[0004] To achieve the above objectives, this application adopts the following technical solution:

[0005] One aspect of this application provides a camera vibration damping support unit, including an inner sleeve, an outer sleeve, and an annular damping member. The outer sleeve and the annular damping member are both fitted outside the inner sleeve. In a first direction, the annular damping member is located between the inner sleeve and the outer sleeve, and both the inner sleeve and the outer sleeve are in pressure contact with the annular damping member. The first direction is the radial direction of the outer sleeve.

[0006] Optionally, it includes a plurality of the aforementioned annular damping elements, each of the aforementioned annular damping elements being uniformly distributed in a second direction, the second direction being the axial direction of the outer sleeve.

[0007] The beneficial effect of this technical solution is that by using multiple annular damping components, the vibration reduction effect of the camera vibration reduction support unit is improved.

[0008] Optionally, a plurality of annular limiting grooves are formed on the outer wall of the inner sleeve, and each of the annular limiting grooves is evenly distributed in the second direction, and each of the annular damping elements corresponds to and cooperates with each of the annular limiting grooves.

[0009] The beneficial effect of this technical solution is that the position of the annular damping component can be limited by the annular limiting groove, so that when relative vibration occurs between the inner sleeve and the outer sleeve, the annular damping component is less likely to slide in the second direction.

[0010] Optionally, it further includes a first base assembly and a second base assembly, wherein the first base assembly is threadedly connected to one end of the outer sleeve in a second direction, and the end of the inner sleeve away from the first base assembly is threadedly connected to the second base assembly, wherein the second direction is the axial direction of the outer sleeve.

[0011] The beneficial effects of this technical solution are: it facilitates the quick assembly and disassembly of the first base assembly and the second base assembly, improves the convenience of camera vibration damping support unit production, and increases production speed.

[0012] Optionally, it also includes an elastic pad, the first base assembly including an upper base and a first connector connected to each other, the first connector extending into the outer sleeve and threadedly connected to the outer sleeve, the elastic pad being located between the first connector and the inner sleeve in the second direction, and the elastic pad being in pressure contact with both the first connector and the inner sleeve.

[0013] The beneficial effect of this technical solution is that by setting an elastic pad, the vibration of the inner sleeve relative to the outer sleeve in the second direction is further suppressed, thereby further improving the vibration reduction effect of the camera vibration damping support unit.

[0014] Optionally, it further includes a pressure ring and an annular rigid pad. The first joint has an axial inner hole. In the second direction, the first joint, the pressure ring, the elastic pad, the annular rigid pad, and the inner sleeve are in sequential contact. The inner hole diameter of the pressure ring is smaller than the axial inner hole diameter of the first joint, and the inner hole diameter of the annular rigid pad is smaller than the inner hole diameter of the inner sleeve.

[0015] The beneficial effects of this technical solution are as follows: compared with making the first joint and the inner sleeve directly contact the elastic pad, the contact area is increased by setting the pressure ring and the annular rigid pad to contact the elastic pad, and the elastic pad is more firmly fixed between the pressure ring and the annular rigid pad, so that the elastic pad is less likely to produce large displacement during vibration, thereby improving the reliability of the camera vibration damping support unit.

[0016] Optionally, the second base assembly includes a second connector and a lower base, one end of the second connector being threadedly connected to the inner sleeve, and the other end of the second connector being connected to the lower base via a spherical bearing.

[0017] The beneficial effect of this technical solution is that the second joint is connected to the lower base ball joint, so that the joint bearing can provide the joint of the camera damping support unit with three degrees of rotational freedom, thereby at least partially eliminating the effects of insufficient flatness and thermal deformation on the camera.

[0018] Optionally, it also includes a pin and a nut. The second connector includes a U-shaped end. One end of the lower base is a connecting end. The connecting end extends into the U-shaped end. The pin passes through the U-shaped end and the connecting end. The pin is connected to the U-shaped end through the nut. The outer ring of the spherical bearing is installed on the connecting end. The inner ring of the spherical bearing is fitted onto the pin.

[0019] Optionally, it also includes an inner ring pressure block and an outer ring pressure block, both fitted onto the pin shaft. The U-shaped end includes a first pressure plate and a second pressure plate. The inner ring pressure block, the outer ring pressure block, and the spherical bearing are all located between the first pressure plate and the second pressure plate. In the axial direction of the pin shaft, the inner ring pressure block is located between the inner ring and the first pressure plate, and the outer ring pressure block is located between the outer ring and the second pressure plate. The outer ring pressure block is fixed to the connecting end.

[0020] The beneficial effects of this technical solution are as follows: In this way, the relative position of the spherical plain bearing in the axial direction of the pin shaft relative to the second joint and the lower base can be limited by the inner ring pressure block and the outer ring pressure block, making the spherical plain bearing less prone to shaking and improving stability and reliability; During assembly, before the nut is connected to the pin shaft, a certain gap is left between the inner ring pressure block and the first pressure plate bracket to facilitate assembly. After the nut is connected to the pin shaft, the nut is rotated to press the first pressure plate, which in turn presses the inner ring pad block, thereby limiting the position of the spherical plain bearing.

[0021] Another aspect of this application provides a camera vibration damping support assembly, including two camera vibration damping support units provided in the embodiments of this application, wherein the upper base of one camera vibration damping support unit is integrally formed with the upper base of the other camera vibration damping support unit.

[0022] The technical solution provided in this application can achieve the following beneficial effects:

[0023] The camera vibration damping support unit and camera vibration damping support assembly provided in this application utilize an annular damping element installed between the inner sleeve and the outer sleeve, ensuring pressure contact between the annular damping element and both the inner sleeve and the outer sleeve. This replaces the current method of injecting damping adhesive, achieving the effect of generating axial damping force between the inner sleeve and the outer sleeve. The production of the annular damping element can be carried out simultaneously with the production of the inner sleeve and the outer sleeve, and then assembled with the inner sleeve and the outer sleeve after the annular damping element is produced. This saves the time of waiting for the damping adhesive to dry after injection, shortening the production cycle of the camera vibration damping support unit. Furthermore, the inner sleeve, the outer sleeve, and the annular damping element are flexible to disassemble and assemble, allowing for quick disassembly and assembly, further shortening the production cycle.

[0046] The technical solutions of this application will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

Therefore, they should not be construed as limitations on this application. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0049] like Figures 1 to 7 As shown, one aspect of this application provides a camera vibration damping support unit 100, including an inner sleeve 04, an outer sleeve 03, and an annular damping member 09. The outer sleeve 03 and the annular damping member 09 are both fitted outside the inner sleeve 04. In a first direction, the annular damping member 09 is located between the inner sleeve 04 and the outer sleeve 03, and both the inner sleeve 04 and the outer sleeve 03 are in pressure contact with the annular damping member 09. The first direction is the radial direction of the outer sleeve 03.

[0050] In this embodiment, the annular damping element 09 is preferably a damping rubber ring.

[0051] The camera vibration damping support unit 100 provided in this application embodiment uses an annular damping element 09 installed between the inner sleeve 04 and the outer sleeve 03, ensuring that the annular damping element 09 is in pressure contact with both the inner sleeve 04 and the outer sleeve 03. This replaces the current method of injecting damping glue, achieving the effect of generating axial damping force between the inner sleeve 04 and the outer sleeve 03. The production of the annular damping element 09 can be carried out simultaneously with the production of the inner sleeve 04 and the outer sleeve 03. After the annular damping element 09 is produced, it is assembled with the inner sleeve 04 and the outer sleeve 03. This saves the time of waiting for the damping glue to dry after injection, shortening the production cycle of the camera vibration damping support unit 100. Furthermore, the inner sleeve 04, the outer sleeve 03, and the annular damping element 09 are flexible to disassemble and assemble, allowing for quick disassembly and assembly, further shortening the production cycle.

[0052] Optionally, the camera vibration damping support unit 100 provided in this application embodiment includes a plurality of the aforementioned annular damping elements 09, each of the annular damping elements 09 being evenly distributed in a second direction, the second direction being the axial direction of the outer sleeve 03. Having a plurality of annular damping elements 09 improves the vibration damping effect of the camera vibration damping support unit 100. In this application embodiment, the specific number of annular damping elements 09 can be specifically selected as needed, for example, 5-10, and preferably 8 in this application embodiment.

[0053] Optionally, a plurality of annular limiting grooves are formed on the outer wall of the inner sleeve 04, and the annular limiting grooves are evenly distributed in the second direction. Each annular damping member 09 corresponds to and cooperates with each annular limiting groove. In this way, the position of the annular damping member 09 can be limited by the annular limiting grooves, so that when relative vibration occurs between the inner sleeve 04 and the outer sleeve 03, the annular damping member 09 is less likely to slide in the second direction.

[0054] Optionally, the camera vibration damping support unit 100 provided in this application embodiment further includes a first base assembly and a second base assembly. In a second direction, the first base assembly is threadedly connected to one end of the outer sleeve 03, and the end of the inner sleeve 04 furthest from the first base assembly is threadedly connected to the second base assembly. The second direction is the axial direction of the outer sleeve 03. This facilitates quick assembly and disassembly of the first and second base assemblies, improving the ease of production of the camera vibration damping support unit 100 and increasing production speed.

[0055] Optionally, the camera vibration damping support unit 100 provided in this application embodiment further includes an elastic pad 18. The first base assembly includes an upper base 01 and a first connector 02 connected to each other. The first connector 02 extends into the outer sleeve 03 and is threadedly connected to the outer sleeve 03. In the second direction, the elastic pad 18 is located between the first connector 02 and the inner sleeve 04, and the elastic pad 18 is in pressure contact with both the first connector 02 and the inner sleeve 04. By setting the elastic pad 18, the vibration of the inner sleeve 04 relative to the outer sleeve 03 in the second direction is further suppressed, and the vibration damping effect of the camera vibration damping support unit 100 is further improved. The elastic pad 18 provides stiffness and elastic deformation. The material used to make the elastic pad 18 is relatively flexible. Different materials used to make the elastic pad 18 have different stiffnesses. The thickness, outer diameter, and inner diameter of the elastic pad 18 can be adjusted according to the actual load. The elastic pad 18 can be prefabricated and then assembled without the need for injection. If the stiffness of the camera vibration damping support unit 100 needs to be adjusted, it can be achieved by replacing the elastic pad 18 with one made of a different material.

[0056] Optionally, the camera vibration damping support unit 100 provided in this application embodiment further includes a pressure ring 19 and an annular rigid pad 20. The first connector 02 has an axial inner hole. In the second direction, the first connector 02, the pressure ring 19, the elastic pad 18, the annular rigid pad 20, and the inner sleeve 04 are in sequential contact. The inner diameter of the pressure ring 19 is smaller than the axial inner diameter of the first connector 02, and the inner diameter of the annular rigid pad 20 is smaller than the inner diameter of the inner sleeve 04. Compared to having the first connector 02 and the inner sleeve 04 directly contact the elastic pad 18, setting the pressure ring 19 and the annular rigid pad 20 to contact the elastic pad 18 increases the contact area, more firmly fixing the elastic pad 18 between the pressure ring 19 and the annular rigid pad 20, making the elastic pad 18 less prone to large displacement during vibration, and improving the reliability of the camera vibration damping support unit 100. Preferably, the annular rigid pad 20 is a T-shaped pad made of metal, with one protruding end of the T-shaped pad extending into the inner hole of the inner sleeve 04, thereby positioning the relative position of the T-shaped pad and the inner sleeve 04.

[0057] Optionally, the second base assembly includes a second connector 05 and a lower base 07. One end of the second connector 05 is threadedly connected to the inner sleeve 04, and the other end of the second connector 05 is connected to the lower base 07 via a spherical bearing 17. That is, the second connector 05 is ball-jointed to the lower base 07, so that the spherical bearing 17 can provide the joint of the camera damping support unit 100 with three degrees of rotational freedom, thereby at least partially eliminating the effects of insufficient flatness and thermal deformation on the camera. In this embodiment, the first connector 02 and the upper base 01 can also be connected using a spherical bearing 17.

[0058] Optionally, the camera vibration damping support unit 100 provided in this application embodiment further includes a pin 08 and a nut 06. The second connector 05 includes a U-shaped end. One end of the lower base 07 is a connecting end 21. The connecting end 21 extends into the U-shaped end. The pin 08 passes through the U-shaped end and the connecting end 21. The pin 08 is connected to the U-shaped end through the nut 06. The outer ring 10 of the spherical bearing 17 is installed on the connecting end 21, and the inner ring 13 of the spherical bearing 17 is fitted onto the pin 08.

[0059] Optionally, the camera vibration damping support unit 100 provided in this application embodiment further includes an inner ring pressure block 14 and an outer ring pressure block 12, both fitted onto the pin shaft 08. The U-shaped end includes a first pressure plate 16 and a second pressure plate 11. The inner ring pressure block 14, the outer ring pressure block 12, and the spherical bearing 17 are all located between the first pressure plate 16 and the second pressure plate 11. In the axial direction of the pin shaft 08, the inner ring pressure block 14 is located between the inner ring 13 and the first pressure plate 16, and the outer ring pressure block 12 is located between the outer ring 10 and the second pressure plate 11. The outer ring pressure block 12 is fixed to the connecting end 21. In this way, the inner ring pressure block 14 and the outer ring pressure block 12 can limit the relative position of the spherical plain bearing 17 in the axial direction of the pin 08 relative to the second joint 05 and the lower base 07, making the spherical plain bearing 17 less prone to shaking and improving stability and reliability. During assembly, before the nut 06 is connected to the pin 08, a certain gap is left between the inner ring pressure block 14 and the first pressure plate 16 bracket to facilitate assembly. After the nut 06 is connected to the pin 08, rotating the nut 06 causes the nut 06 to press against the first pressure plate 16, which in turn causes the first pressure plate 16 to press against the inner ring pressure block, thereby limiting the position of the spherical plain bearing 17. Preferably, a washer 15 is installed between the nut 06 and the first pressure plate 16 bracket. In this embodiment, the structure used in the second base assembly can also be applied to the first base assembly, and the upper base 01 can also be connected to the first joint 02 via the spherical plain bearing 17 and the pin 08.

[0060] Another aspect of this application provides a camera vibration damping support assembly 200, including two camera vibration damping support units 100 provided in the embodiments of this application, wherein the upper base 01 of one camera vibration damping support unit 100 is integrally formed with the upper base 01 of the other camera vibration damping support unit 100.

[0061] The camera vibration damping support assembly 200 provided in this application embodiment adopts the camera vibration damping support unit 100 provided in this application embodiment. By using an annular damping element 09 installed between the inner sleeve 04 and the outer sleeve 03, and ensuring that the annular damping element 09 is in pressure contact with both the inner sleeve 04 and the outer sleeve 03, the current method of injecting damping glue is replaced. This achieves the effect of generating axial damping force between the inner sleeve 04 and the outer sleeve 03. The production of the annular damping element 09 can be carried out simultaneously with the production of the inner sleeve 04 and the outer sleeve 03. After the annular damping element 09 is produced, it is assembled with the inner sleeve 04 and the outer sleeve 03. This saves the time of waiting for the damping glue to dry after injection, shortening the production cycle of the camera vibration damping support unit 100. Furthermore, the inner sleeve 04, the outer sleeve 03, and the annular damping element 09 are flexible to disassemble and assemble, and can be quickly disassembled and assembled, further shortening the production cycle.

[0062] To better illustrate the camera vibration damping support unit and camera vibration damping support assembly 200 provided in this application, this application also provides an application example of the camera vibration damping support unit and camera vibration damping support assembly 200. In this application example, the first connector is also referred to as the outer connector, the second connector is also referred to as the inner connector, and the camera vibration damping support unit is also referred to as the support rod assembly.

[0063] The support rod assembly consists of an outer sleeve, an inner sleeve, an inner connector, an outer connector, an upper base, a lower base, a bearing assembly, and rubber pads. The inner sleeve connects to the inner connector, and the outer sleeve connects to the outer connector. The inner and outer sleeves can slide relative to each other. Elastic rubber pads are installed at both ends of the inner sleeve, and grooves are designed on the outer circumference of the inner sleeve for installing damping rubber rings.

[0064] The inner joint is connected to the lower base via a spherical bearing assembly, and the outer joint is connected to the upper base via a spherical bearing assembly, providing two ball joint connections for the support rod assembly.

[0065] The enlarged view of the bearing assembly is shown in the figure below. The pin passes through the joint, the spherical plain bearing, the inner ring pressure block, and the washer, and is tightened by the nut. The inner and outer rings of the spherical plain bearing are firmly pressed together. There is a certain gap between the inner ring pressure block and the joint, which can generally be 0.01~0.05mm. Tightening the nut causes the joint to deform and press the inner ring pressure block, thereby pressing the spherical plain bearing.

[0066] The core invention of this invention is a damped elastic support, as shown in the figure below. Several damping rubber rings are installed on the outer side of the inner sleeve. These rubber rings are prefabricated instead of being injected with adhesive; during assembly, they simply need to be fitted onto the grooves. The damping force can be adjusted by the number of damping rubber rings. This damping adhesive primarily serves a damping function and can be made of materials with good damping properties, such as silicone or polyurethane adhesive.

[0067] Similarly, elastic rubber pads are installed on both sides of the inner sleeve, mainly to provide the required stiffness and elastic deformation. These rubber pads can be made of rubber with high stiffness, and their thickness, outer diameter, and inner diameter can be adjusted according to the actual load. These rubber pads are prefabricated, requiring no grouting, making installation convenient and quick. If the stiffness of the support rod needs adjustment, this can also be achieved quickly by replacing the rubber pads without altering the structure.

[0068] T-shaped pads can provide limiting protection for rubber pads to prevent them from being crushed under excessive impact.

[0069] The outer connector and the outer sleeve are connected by threads.

[0070] The main advantages of this invention are:

[0071] 1. Pre-made solid rubber pads can be used for elastic rubber pads, which do not require glue injection and curing. The process is simple and reliable, and the stiffness can be adjusted by replacing the rubber pads.

[0072] 2. The damping rubber ring is also a pre-made rubber ring, which does not require injection and has a simple process. In addition, the damping value can be adjusted by the number of rubber rings.

[0073] 3. The bearing assembly is installed in a way that ensures the inner and outer rings of the bearing are securely and reliably clamped together, and the operation is convenient.

[0074] The key technical points of this invention are two:

[0075] 1. The use of damping rubber rings allows for adjustment of damping by increasing the number of rubber rings; the use of elastic rubber pads allows for adjustment of support stiffness by replacing the rubber pads; in short, it can achieve adjustable support stiffness and damping, has a wide range of applications, a short production cycle, and low cost.

[0076] 2. The installation method of the spherical plain bearing assembly, the inner ring of the bearing is clamped by the deformation of the joint after compression, which provides sufficient clamping force and is firm and reliable.

[0077] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
