[0029] This embodiment relates to a pediatric endoscope, as shown in the reference... Figures 1-8 The device includes a handheld terminal 10, a camera assembly 20, and a protective case 30. The handheld terminal 10 includes an image display unit 11 with a display screen 12. The camera assembly 20 is detachably connected to the handheld terminal 10 and electrically connected to the display screen 12, enabling the images captured by the camera assembly 20 to be transmitted to the display screen 12 for display. The protective case 30 detachably covers the circumferential edge of the image display unit 11 and has an observation hole corresponding to the display screen 12.

[0030] The camera assembly 20 includes a camera body 21 and a connecting tube 22. The two ends of the connecting tube 22 are fixedly connected to the camera body 21 and the handheld terminal 10, respectively. The connecting tube 22 has wires inside, and the camera body 21 is electrically connected to the handheld terminal 10 through the wires.

[0031] In use, the camera component 20 captures video images and transmits them to the display screen 12 in real time for display, allowing users to observe the images captured by the camera component 20 in real time on the display screen 12. By covering the circumferential edge of the image display section 11 with the protective case 30, the display screen 12 is protected. When the device is dropped or impacted or squeezed by hard objects, the protective case 30 can protect the display screen 12, thereby effectively preventing the display screen 12 from breaking.

[0032] Furthermore, the protective case 30 protrudes from the display screen 12.

[0033] The protective shell 30 protruding from the display screen 12 means that the circumferential edge of the protective shell 30 extends outward relative to the plane of the display screen 12 when installed. When the protective shell 30 covers the circumferential edge of the image display section 11, the flange portion of the protective shell 30 completely covers the edge area of ​​the display screen 12 and extends outward. When the device is dropped or squeezed by a hard object, the flange first bears the external impact load and absorbs energy through its own material deformation, preventing the four corners and edges of the display screen 12 from directly contacting the impact surface. During this process, an isolation space is formed between the flange of the protective shell 30 and the display screen 12, further reducing the risk of impact stress being transmitted to the display screen 12.

[0034] In addition, the protective shell is also provided with decorative parts 301. In this embodiment, the decorative parts 301 are cat eyes and cat ears. In other embodiments, the decorative parts 301 can also be decorative products of other shapes or structures. The protective shell is made of one or more of silicone, thermoplastic polyurethane, thermoplastic elastomer and soft rubber.

[0035] Furthermore, a fixing frame 40 is provided between the image display unit 11 and the protective shell 30, the protective shell 30 is fitted onto the fixing frame 40, and the protective shell 30 is fixedly connected to the image display unit 11 through the fixing frame 40.

[0036] By setting a fixing frame 40 between the image display unit 11 and the protective shell 30, the protective shell 30 and the image display unit 11 can be detachably connected, thereby facilitating the assembly of the protective shell 30. At the same time, by adding the fixing frame 40 to form a secondary buffer structure, the assembly interface of the protective shell 30 and the installation interface of the display screen 12 are spatially isolated, effectively reducing the direct impact of mechanical vibration on the display screen 12.

[0037] Furthermore, the image display unit 11 has a mounting slot 111, and the fixing frame 40 is installed in the mounting slot 111.

[0038] During installation, first fix the fixing frame 40 in the mounting slot 111, and then fix the protective shell 30 on the fixing frame 40, thereby installing the protective shell 30 on the image display unit 11. The operation is simple and convenient, and it is also easy to replace the protective shell 30.

[0039] It should be explained that the fixing frame 40 is used to fix the protective shell 30, so that the protective shell 30 is not easy to shift, thereby stably protecting the display screen 12.

[0040] Furthermore, the size of the mounting groove 111 is adapted to the size of the protective shell 30. The inner wall of the mounting groove 111 is provided with multiple slots 1111, and the outer wall of the fixing frame 40 is provided with multiple blocks 41, which engage with the slots 1111.

[0041] When the protective shell 30 needs to be installed onto the image display unit 11, the fixing frame 40 is first embedded into the mounting groove 111. Since the size of the mounting groove 111 matches that of the protective shell 30, the locking block 41 on the outer wall of the fixing frame 40 undergoes elastic deformation under pressure until it is fully embedded into the groove 1111. At this time, the contact surface between the locking block 41 and the groove 1111 forms an interlocking structure, preventing the fixing frame 40 from shifting when subjected to external force.

[0042] Furthermore, a fixed space 112 is formed between the fixed frame 40 and the bottom wall of the mounting groove 111, and a limiting ring 31 is provided on the inner wall of the protective shell 30, which is located within the fixed space 112.

[0043] During installation, the protective shell 30 is embedded in the fixing space 112 via the limiting ring 31. The fixing space 112 circumferentially wraps around the limiting ring 31, thus positioning and constraining the protective shell 30. When an external impact force is applied to the protective shell 30, the contact surface between the limiting ring 31 and the fixing space 112 forms a support, allowing the impact force to be transmitted through the fixing frame 40 to the bottom wall of the mounting groove 111, preventing it from directly impacting the display screen 12 area.

[0044] Furthermore, the inner wall of the mounting groove 111 is provided with a limiting flange 1112, and the limiting ring 31 is provided with a limiting groove 311 that cooperates with the limiting flange 1112 at the position corresponding to the limiting flange 1112.

[0045] The limiting flange 1112 refers to the protruding structure circumferentially arranged along the inner wall of the mounting groove 111, and the limiting groove 311 refers to the recessed structure formed on the inner side wall of the limiting ring 31. During the assembly of the protective shell 30, the fixing frame 40 slides along the surface of the limiting flange 1112 of the mounting groove 111 until the limiting flange 1112 is embedded in the limiting groove 311 of the limiting ring. The cooperation between the limiting flange 1112 and the limiting groove 311 forms a positioning constraint, preventing the protective shell 30 from detaching from the fixing frame 40 due to inertial force when the equipment is dropped. At the same time, the circumferential wrapping of the limiting flange 1112 by the limiting groove 311 can prevent the protective shell 30 from rotating due to external pressure, thereby maintaining the precise alignment between the observation hole and the display screen 12.

[0046] Furthermore, the inner wall of the mounting groove 111 is provided with at least one guide groove 1113, and the fixing frame 40 is provided with at least one guide block 42 for sliding cooperation with the guide groove 1113.

[0047] The guide groove 1113 and guide block 42 work together to guide the fixed frame 40 to move in a predetermined direction, thereby ensuring the stability of the fixed frame 40's movement trajectory during installation. In other words, the guide groove 1113 and guide block 42 work together to limit the movement path of the fixed frame 40, preventing the fixed frame 40 from shifting position during installation, thereby improving assembly accuracy.

[0048] Furthermore, the image display section 11 is recessed to form a protective groove 113, and the display screen 12 is disposed on the bottom wall of the protective groove 113.

[0049] The protective groove 113 refers to the receiving space formed by the inward recess of the surface of the image display unit 11. The display screen 12 is located on the bottom wall of the protective groove 113, meaning that the mounting plane of the display screen 12 is fitted and fixed to the bottom of the protective groove 113. Specifically, when the image display unit 11 is subjected to external impact, the recessed structure of the protective groove 113 causes the edge area to contact the external object first, and the impact force is dispersed and transmitted to the housing of the image display unit 11 through the side wall, avoiding direct impact on the surface of the display screen 12.

[0050] Furthermore, the sidewall of the fixing frame 40 is arc-shaped, and the inner wall of the protective shell 30 corresponds to the shape of the outer wall of the fixing frame 40.

[0051] When the protective shell 30 is installed onto the fixed frame 40, the curved surface of its inner wall is in complete contact with the arc-shaped outer surface of the side wall of the fixed frame 40. When subjected to external pressure or impact, the geometric characteristics of the arc-shaped side wall can evenly transmit the impact energy along the curved surface to the fixed frame 40. At the same time, the contact surfaces of the protective shell 30 and the fixed frame 40 form multi-point contact support, avoiding excessive local stress that could lead to structural deformation.

[0052] In another embodiment, the handheld terminal 10 further includes a control module 50, a battery module 60, and a button module 70. The control module 50, battery module 60, and button module 70 are all electrically connected. The display screen 12 and camera assembly 20 are both electrically connected to the control module 50 to control the display screen 12 and camera assembly 20. The battery module 60 supplies power to the display screen 12 and camera assembly 20, enabling them to operate stably. Since the control module 50, battery module 60, and button module 70 are conventional technologies in the art and not the focus of this invention, they will not be described in detail.

[0053] The above is only used to illustrate the technical solution of the present invention and is not intended to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of the present invention, as long as they do not depart from the spirit and scope of the technical solution of the present invention, should be covered within the scope of the claims of the present invention.
