Description

Technical Field

[0001] The utility model relates to the technical field of optical elements, and more specifically, to an asphalt-based carbon fiber reflector seat. Background Art

[0002] The reflector is a component that is of great significance in the field of optics, especially in high-end application scenarios such as space optical remote sensing technology.

[0003] High-end scientific research equipment, such as high-precision scientific instruments, large astronomical telescopes, and optical mirror systems in high-energy physics experimental equipment, requires high precision, temperature resistance, and stability to ensure the optical performance of the mirrors. In these devices, even the slightest error can lead to deviations in experimental results or inaccurate observation data.

[0004] Traditional reflector mounts are mostly made of metal, particularly titanium alloy, due to its high strength and corrosion resistance. However, titanium alloy's high coefficient of thermal expansion affects the optical performance of the reflector and is also expensive. In recent years, carbon fiber composites have become a new choice for reflector mounts due to their lightweight, high strength, and low coefficient of thermal expansion.

[0005] Compared with traditional metal materials, carbon fiber materials can reduce the weight of the entire equipment, facilitate the transportation, installation and operation of the equipment, have very precise surface flatness and dimensional tolerance, good seismic performance, extremely low thermal expansion coefficient, and corrosion resistance and temperature resistance, which are extremely important in the fields of astronomical observation and aerospace optical detection.

[0006] Although the use of carbon fiber materials for reflectors offers many advantages, there are still many drawbacks when installing the reflectors. For example, the existing carbon fiber mirror mount has a highly compact structure, which prevents internal components such as cables from dissipating sufficient heat, resulting in poor heat dissipation performance. Furthermore, due to the small openings on the mount, wrenches and screwdrivers are difficult to use, making installation extremely difficult and resulting in poor functionality. Utility Model Content

[0007] The utility model aims to overcome the defects of the above-mentioned prior art and provide an asphalt-based carbon fiber reflector seat for solving the technical problems of poor heat dissipation performance, difficult operation during installation and poor functionality.

[0008] The technical solution adopted by the present invention is a pitch-based carbon fiber reflector seat, which includes an upper box body and a lower box body, and the upper box body is fixed on the lower box body, wherein: the rear end face of the upper box body is an opening; the upper end face and the lower end face of the upper box body are both provided with mounting holes; the longitudinal cross-section of the lower box body is a trapezoid, which has a longer upper end face, a shorter lower end face and two front and rear inclined faces, the front and rear inclined faces are both openings, and two mounting holes are provided on the longer upper end face along its length direction; after fixation, the mounting holes on the upper end face of the upper box body, the mounting holes on the lower end face of the upper box body and the mounting holes on the rear side of the upper end face of the lower box body are concentric.

[0009] The upper and lower boxes are fixed together to form a frame structure with high structural strength, ensuring the optical performance and reliability of the reflector holder. The mounting holes on the upper and lower boxes are used to install the reflectors. The rear end face of the upper box is open, and the two inclined surfaces of the lower box are open, which can effectively ensure the heat dissipation of the internal components. The opening design makes operation more convenient and can effectively improve its functionality.

[0010] Preferably, the width of the upper case is greater than that of the lower case. When the upper and lower cases are secured, the left end face of the upper case is coplanar with the left end face of the lower case, and the right end of the upper case protrudes beyond the right end of the lower case. This design increases the width of the upper case, providing more operating space and making it easier for installation tools to enter, improving installation convenience and functionality, while also ensuring alignment of the left end face and ensuring structural stability.

[0011] Preferably, the front right side of the upper housing has a vertical protrusion, the width of which is greater than the protrusion of the upper housing from the lower housing. This protrusion provides more operating space for installation tools, making them easier to access and operate, and improving installation convenience. Furthermore, the protrusion's width, which is greater than the protrusion of the upper housing, further enhances structural stability.

[0012] Preferably, the angle between the protrusion and the front end surface of the upper box body is rounded. The rounded corner design improves the impact resistance and durability of the structure, while making the appearance smoother and reducing the risk of scratches and damage.

[0013] Preferably, the upper box body and the lower box body are fixed by resin adhesive. The resin adhesive fixing method is not only simple to operate but also has strong bonding strength, which can ensure the close connection between the upper box body and the lower box body, thereby improving the stability and reliability of the overall structure.

[0014] Preferably, the upper and lower housings are formed by mortise and tenon joints of asphalt-based carbon fiber panels, wherein the panels are cut from rectangular asphalt-based carbon fiber panels. The mortise and tenon joint enhances structural stability and reliability, and compared to mechanical connections (such as bolts and rivets), effectively avoids defects such as cracks or delamination caused by stress concentration. During processing or use, carbon fibers may break, resulting in localized strength loss. The mortise and tenon joint process eliminates the need to cut numerous cavities in the panels, effectively improving their structural strength and avoiding numerous internal defects.

[0015] Preferably, a U-shaped groove is provided on the front side of the bottom splicing plate of the upper case. When the upper case and the lower case are secured, a wiring hole is formed between the top surface of the lower case, the U-shaped groove, and the bottom of the splicing plate at the front end of the upper case. The wiring hole has an L-shaped structure, connecting the interior of the upper case with the outside. The L-shaped wiring hole design effectively solves the heat dissipation problem of internal cables and other components, while providing a channel for cable entry and exit, improving the heat dissipation performance and functionality of the reflector base.

[0016] Preferably, one side of the U-shaped groove is a curved surface tangent to the top surface of the lower box body. The curved surface design improves the impact resistance and durability of the structure, while making the transition between the U-shaped groove and the top surface of the lower box body smoother, reducing friction and damage risks during installation.

[0017] Preferably, a U-shaped positioning notch 1 is provided on the front side of the shorter lower end face of the lower housing, with the inner angle of the positioning notch 1 being a right angle; and a circular arc-shaped positioning notch 2 is provided on the rear side of the shorter lower end face of the lower housing. The design of the positioning notch 1 and the positioning notch 2 provides precise positioning points, ensuring the position accuracy of the reflector mount during installation and avoiding installation errors and degradation of optical performance due to positional offset.

[0018] Preferably, the centers of the mounting holes on the upper end face of the upper housing, the mounting holes on the lower end face of the upper housing, the mounting holes on the rear side of the lower housing, and the arc center of the second positioning notch are located on the same vertical line. This design ensures that the centers of all mounting holes and positioning notches are located on the same vertical line, further improving installation accuracy and stability, avoiding structural instability caused by misaligned holes, and ensuring the optical performance and reliability of the reflector mount.

[0019] Compared with the prior art, the beneficial effects of the present invention are as follows: the upper box and the lower box are used, which, after being fixed, form a frame structure with high structural strength, thereby ensuring the optical performance and reliability of the reflector seat; a U-shaped groove is provided at the bottom of the front end of the upper box, the rear end face is an opening, and the two inclined surfaces of the lower box are openings, which can effectively ensure the heat dissipation of the internal components; the opening design is more convenient to operate and can effectively improve its functionality.
