[0021] An embodiment of the present invention is shown in the figure. In order to achieve the above-mentioned purpose, the present invention provides a detection component of a compact handheld eye detection device, including a shell 1, in which a fundus camera 2, a slit lamp 3 and a platform 4 are arranged. The platform 4 is connected to the shell 1, and the platform 4 has an upper part 41 and a lower part 42. A first notch 5 for accommodating the fundus camera 2 and the slit lamp 3 is formed between the upper part 41 and the lower part 42. The slit lamp 3 is provided with a first cut surface 31 on the side facing the lower part 42, and a second cut surface 32 is provided on the side corresponding to the upper part 41. The slit lamp 3 is fixedly connected to the bottom by bolts. The first cut surface 31 can be fitted with the lower part 42, and the second cut surface 32 and the upper part 41 are arranged to avoid each other. The slit lamp 3 is partially accommodated in the first notch 5.

[0022] When implementing this solution, the shell 1 is first prepared using equipment, and a platform 4 is set in the shell 1. The shell 1 can be injection molded using lightweight materials, with a preset mounting slot and wiring space on the inner wall, a detection window at the front, and a portion for holding the shell 1. The platform 4 is processed into an upper and lower split structure using plate material, with a first notch 5 formed in the middle to adapt to the shape of the fundus camera 2 and the slit lamp 3, and the edges are rounded. The first notch 5 in this solution is formed by a combination of an upper part 41 and a lower part 42. Then the core components are installed. The fundus camera 2 is first placed in the first notch 5. The platform 4 is connected to the shell of the fundus camera 2 by fixing bolts through the screw holes preset in the upper and lower parts 42 of the platform 4, ensuring that the lens is aligned with the front window of the shell 1. A first cut surface 31 is processed on the bottom of the slit lamp 3 so that it fits with the lower part 42 of the platform 4, and is fixed by bolts. A second cut surface 32 is processed corresponding to the upper part 41 and a clearance space is reserved to avoid interference, so that the lamp body is partially embedded in the notch. At this time, the first cut surface 31 of the slit lamp 3 can also be against the side wall of the fundus camera 2 facing the slit lamp 3. Finally, the whole device is assembled, and the platform 4 with the installed components is fixed to the slot in the shell 1 through the positioning structure. The circuits of each component are connected and the wiring is arranged. During debugging, the light angle of the slit lamp 3 and the shooting position of the fundus camera 2 are calibrated to ensure that the two cooperate to complete the eye detection, and finally a handheld device with a compact structure and easy operation is formed. The platform 4 can also be fixedly connected to the shell 1 before the components are installed, and then the components are installed.

[0023] The fundus camera 2 is arranged in the first gap 5 between the slit lamp 3 and the lower part 42 and is fixedly connected to the lower part 42. The side wall of the fundus camera 2 facing the slit lamp 3 abuts against the first section 31, and the side wall facing the lower part 42 abuts against the inner wall of the first gap 5.

[0024] During the implementation of this solution, after the slit lamp 3 and the fundus camera 2 are installed, part of the first cut surface 31 of the slit lamp 3 abuts against the side wall of the first notch 5, and the remaining part can abut against the fundus camera 2. There is only a gap between the two, which are in a fitted state. The structure is compact and the occupied space is reduced. After the slit lamp 3 and the fundus camera 2 are fitted, the connection between the two is more stable and is not prone to shaking when moving.

[0025] At least one fill light 7 is provided in the shell 1, and the upper part 41 and the lower part 42 are both extended upward to provide a connecting plate 43 for fixing the fill light 7, and the two connecting plates 43 are respectively provided corresponding to the left eye and the right eye of the human body, and a second notch 6 for accommodating the fill light 7 is formed between the two connecting plates 43; there are two fill lights 7, and one is provided corresponding to the position of the left eye and the right eye of the human body.

[0026] During implementation of the present invention, a fill light 7 structure is added to the interior of the housing 1. The upwardly extending connecting plates 43 on the upper portion 41 and lower portion 42 of the platform 4 are positioned to correspond to the positions of the left and right eyes of the human body. A second notch 6 is formed between the two connecting plates 43, the size of which matches the shape of the fill light 7. The fill light 7 comprises two independent modules, mounted on the inner sides of the left and right connecting plates 43, respectively, i.e., between the left connecting plate 43 and the right connecting plate 43, and secured with bolts of appropriate specifications. During installation, the fill light 7 is fixed to the corresponding position of the connecting plate 43, and its angle with the fundus camera 2 is adjusted to avoid reflection interference. The power cord of the fill light 7 is then connected to the internal circuit of the housing 1. In this solution, the connecting plate 43 is integrally formed with the platform 4, making manufacturing more convenient. Finally, the overall debugging is carried out. The brightness of the fill light 7 is controlled by adjusting the power supply parameters, and the illumination angle of the lamp body is fine-tuned to make the left and right eye detection areas evenly illuminated and without obvious shadows, ensuring that the fill light 7 can provide a clear and stable detection light source environment when working in conjunction with the fundus camera 2 and the slit lamp 3. The positions of the left eye and the right eye in this solution refer to the positions where the left eye / right eye can be detected, and do not only refer to the direction facing the left eye / the direction facing the right eye. It only requires the position where the left eye / right eye can be effectively detected. The specific position can be changed according to the detection data required by technical personnel in this field.

[0027] The two connecting plates 43 are each provided with a first reflector 431 for reflecting the light of the fill light 7 at the position corresponding to the left eye and the right eye of the human body.

[0028] When implementing this solution, a first reflector 431 is installed on the connecting plate 43. The first reflector 431 can be glued to one side of the connecting plate 43 for reflecting the light of the fill light 7. The installation of the first reflector 431 can enable the position of the internal structure to be appropriately adjusted, and the position of the light can be adjusted through the first reflector 431.

[0029] The two connecting plates 43 are each provided with a first reflector 431 for reflecting the light of the fill light 7 at the position corresponding to the left eye and the right eye of the human body.

[0030] This solution preferably adopts the arrangement of two first reflectors 431 , one for the left eye and one for the right eye respectively. No matter which pair of glasses a person skilled in the art detects, the intensity of light can be guaranteed to avoid the detection effect being affected by insufficient light.

[0031] The fill light 7 set at the corresponding left eye position is fixedly connected to the connecting plate 43 set at the corresponding left eye position by bolts, and the fill light 7 set at the corresponding right eye position is fixedly connected to the connecting plate 43 set at the corresponding right eye position by bolts; the second section 32 is provided with a second reflector 33 for reflecting the detection light toward the human eye position.

[0032] When implementing the detection assembly of the present invention, a platform 4 with a connecting plate 43 is first prepared: the connecting plates 43 extending upward from the upper portion 41 and the lower portion 42 of the platform 4 correspond to the positions of the left and right eyes of the human body, respectively. Bolt holes are preset on the plate surface, and the fill light 7 is placed between the two connecting plates 43, i.e., the second gap 6. Bolts of appropriate specifications are passed through the holes in the connecting plates 43 and tightened to the fixed end of the fill light 7, so that the lamp body is stably installed and the luminous surface faces the detection direction. The angle of the fill light 7 is adjusted during installation. With respect to the second section 32, a second reflector 33 is fixed to the second section 32 of the upper portion 41 of the slit lamp 3 by means of a slot or adhesive, with the mirror facing the direction of the human eye, to ensure that the detection light can be accurately projected to the detection area after being refracted by the reflector. After the installation is completed, fix the platform 4 to the shell 1, connect the power cord of the fill light 7 to the main control circuit, and synchronously calibrate the illumination angle of the fill light 7 and the reflection path of the reflector during debugging to make the light in the left and right eye areas uniform and the detection light path clear, thereby realizing the efficient eye detection function of multi-component collaboration; the slit lamp involved in the above scheme can be set at other positions in the detection device, such as the right side, upper side, etc. of the detection device, and the corresponding internal structure needs to be changed according to the position of the slit lamp.

[0033] The above description is merely a preferred embodiment of the present invention. The scope of protection of the present invention is not limited to the above embodiment. All technical solutions based on the concept of the present invention are within the scope of protection of the present invention. It should be noted that for those skilled in the art, certain improvements and modifications that do not depart from the principles of the present invention should also be considered within the scope of protection of the present invention.
