Technical Field

[0001] This utility model relates to the technical field of honeycomb cores, panels and subframes, specifically a connection structure for honeycomb cores, panels and subframes. Background Technology

[0002] In many engineering fields, such as the wings and fuselage components of aerospace vehicles, the curtain wall structures of buildings, and the interiors of transportation vehicles, the structural form of honeycomb cores and panels combined with subframes is widely used to achieve lightweight and high-strength performance requirements. However, existing connection structures between honeycomb cores, panels, and subframes have some shortcomings.

[0003] Traditional connection methods often use adhesives for direct bonding. While this method can achieve a connection to some extent, the curing process of the adhesive is greatly affected by environmental factors, which can easily lead to unstable bond strength and reduce the stability of the connection. Moreover, it requires precise positioning and long curing time. Furthermore, when the honeycomb core, panel, and subframe are damaged and need repair or replacement, the existing connection method makes it difficult to quickly disassemble and replace parts, which brings great difficulties to subsequent maintenance work. To address this, we provide a connection structure for the honeycomb core, panel, and subframe. Utility Model Content

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-5 A connection structure for a honeycomb core, a panel, and a subframe includes a honeycomb core body 1 and a panel body 2 that is pluggable and detachable at the top and bottom of the honeycomb core body 1. The side of the panel body 2 closest to the honeycomb core body 1 is in contact with the honeycomb core body 1. A subframe body 3 is provided on the surface of the honeycomb core body 1. The surface of the honeycomb core body 1 is in contact with the inner wall of the subframe body 3. The surface of the panel body 2 is in contact with the inner wall of the subframe body 3. The honeycomb core body 1, the panel body 2, and the subframe body 3 are connected by a connecting and fixing component 4. A limit adjustment component 5 is provided on the subframe body 3.

[0022] The panel body 2 is made of a base layer 201, a sound insulation layer 202 and a reinforcing layer 203. There are two sound insulation layers 202, which are respectively set at the top and bottom of the base layer 201. There are two reinforcing layers 203, which are respectively set on the side of the sound insulation layer 202 away from the base layer 201. The sound insulation layer 202 is made of sound insulation cotton, and the reinforcing layer 203 is made of aluminum alloy plate. The base layer 201, the sound insulation layer 202 and the reinforcing layer 203 are cured in one go by hot pressing molding process.

[0023] By setting the sound insulation layer 202, the sound insulation effect of the panel is improved, and the transmission of noise through the panel is reduced. By setting the reinforcement layer 203, the strength of the panel is improved.

[0024] The connecting and fixing component 4 includes a locking block 41, an insert block 42, and a positioning block 43. There are four locking blocks 41, which are respectively installed on the top and bottom of the honeycomb core body 1. A slot 44 is opened on the side of the panel body 2 near the honeycomb core body 1, corresponding to the position of the locking block 41. The side of the locking block 41 near the slot 44 passes through the slot 44 and extends into it. There are two insert blocks 42, which are respectively installed on the left and right sides of the honeycomb core body 1. Slots 45 are opened on both the left and right sides of the inner wall of the subframe body 3. The side of the insert block 42 near the slot 45 passes through the slot 45 and extends into it, contacting the inner wall of the slot 45. There are four positioning blocks 43, which are respectively installed on the left and right sides of the two panel bodies 2. A positioning groove 46 is opened on the top and bottom of the subframe body 3, corresponding to the position of the positioning block 43. The side of the positioning block 43 near the positioning groove 46 passes through the positioning groove 46 and extends into it, contacting the inner wall of the positioning groove 46.

[0025] The limit adjustment component 5 includes two fixed grooves 51, which are respectively opened on the left and right sides of the subframe body 3. A threaded rod 52 is rotatably connected to the groove of the inner wall of the fixed groove 51 through a bearing. A moving block 53 is threadedly connected to the surface of the threaded rod 52. A limit block 54 is fixedly connected to the side of the moving block 53 near the positioning block 43 and corresponding to the position of the positioning block 43. A limit groove 55 is opened on the side of the positioning block 43 near the limit block 54. The side of the limit block 54 near the limit groove 55 passes through the positioning groove 46 and the limit groove 55 in sequence and extends into the interior of the limit groove 55 and contacts the inner wall of the limit groove 55. A rotating block 56 is fixedly connected to the ends of the two threaded rods 52 that are far away from each other. An installation groove is opened on the side of the rotating block 56 that is far away from the threaded rod 52. An operating handle is installed on the inner wall of the installation groove, which facilitates the operation of the rotating block 56.

[0026] Two positioning rods 57 are installed on the left side of the inner wall of the fixing groove 51. The right end of the positioning rod 57 passes through the moving block 53 and extends to its outside and is fixedly connected to the inner wall of the fixing groove 51. By setting the positioning rods 57, the stability of the moving block 53 when moving left and right is improved.

[0027] The surface of the rotating block 56 is provided with an annular groove 58. An annular block 59 is installed on the inner wall of the fixed groove 51 at the position corresponding to the annular groove 58. The side of the annular block 59 close to the annular groove 58 passes through the annular groove 58 and extends into its interior to make rotational contact with the inner wall of the annular groove 58. By setting the annular groove 58 and the annular block 59, the stability of the rotating block 56 during rotation is improved. The friction generated after the annular block 59 and the annular groove 58 come into contact prevents the rotating block 56 from rotating on its own.

[0028] Through the cooperation of the card block 41 and the card slot 44, the cooperation of the insertion block 42 and the slot 45, and the cooperation of the positioning block 43 and the positioning groove 46, a three-dimensional positioning is formed, which can achieve a stable connection between the honeycomb core, the panel and the subframe without relying on adhesives. During disassembly, there is no need to damage the parts or use additional tools. Only by releasing the locking state of the limit adjustment component 5, the panel body 2, the honeycomb core body 1 and the subframe body 3 can be separated in sequence, realizing the independent replacement of individual parts, which greatly reduces maintenance costs and time.

[0029] In use, the honeycomb core body 1 drives the insert block 42 to be inserted into the slot 45 from front to back. Then, the panel body 2 drives the slot 44 to move closer to the slot block 41, so that the slot block 41 is inserted into the corresponding slot 44. At the same time, the positioning block 43 is inserted into the positioning groove 46. Then, the rotating block 56 is rotated, which drives the threaded rod 52 to rotate. The threaded rod 52 drives the moving block 53 to move closer to the honeycomb core body 1. The moving block 53 drives the limiting block 54 to move closer to the limiting groove 55, so that the limiting block 54 is inserted into the limiting groove 55. This completes the connection and fixation of the honeycomb core body 1, the panel body 2 and the subframe body 3.
