Technical Field
[0001] The utility model relates to the field of thermal resistance structures, in particular to a temperature thermal resistance structure of a camera module for an endoscope. Background Art
[0002] At present, a Chinese utility model with the announcement number CN219480027U discloses an endoscope camera mounting structure and an endoscope system, wherein the endoscope camera mounting structure includes: a housing; a camera circuit board disposed in the housing; and a heat sink disposed in the housing; the camera circuit board has at least one heat source; and the heat sink is thermally connected to the housing and to the at least one heat source. The utility model can effectively conduct the heat generated by at least one heat source on the camera circuit board to the housing for heat dissipation by dissipating the camera circuit board and the heat sink in the housing, and the heat sink is thermally connected to at least one heat source on the camera circuit board and the housing, thereby reducing the temperature inside the endoscope camera, preventing the circuit board and the chip from working in a high temperature environment, and effectively improving the imaging quality and service life of the endoscope camera.
[0003] Although the camera module in the existing endoscope system can guide the heat outward through the heat sink, there are still other problems during use, such as poor thermal conductivity stability. The module needs to be smaller than the endoscope to be inserted. Therefore, there is a gap between the module and the endoscope housing, which needs to be filled by personnel later. The operation is cumbersome and complicated, and there is no limiting function. The module is in an active state after being placed in the housing. When the module is shaken, it is very easy to collide with the housing, which reduces the service life of the module. In order to solve the above-mentioned problems, we propose a temperature resistance structure of a camera module for an endoscope. Utility Model Content
[0004] The utility model aims to provide a camera module temperature thermal resistance structure for an endoscope, which solves the problem that the existing module thermal resistance structure has poor thermal conductivity stability and lacks a limiting function.

[0006] The above technical solution can improve the thermal conductivity of the module, so that the heat generated by the module is evenly and fully distributed outward, with high safety. At the same time, it can have a limit function to prevent the module from shaking in the shell, extend the service life of the module, and have high practicality.
[0007] The utility model is further configured as follows: a protective mirror is embedded in the through groove.
[0008] By adopting the above technical solution and setting the protective glasses, the lens end of the camera module can be protected.
[0009] The utility model is further configured as follows: a buffer pad is installed on one side of the limit plate close to the camera module.
[0010] By adopting the above technical solution and providing a buffer pad, the rear end substrate of the camera module can be protected to avoid scratches on the rear end substrate.
[0011] The utility model is further configured as follows: the threaded rod and the nut are both made of stainless steel.
[0012] By adopting the above technical solution, the threaded rod and the nut have the characteristics of high strength, low density and excellent corrosion resistance.
[0013] The utility model is further configured as follows: the camera module is composed of a focus motor, a lens group, a filter, a sensor and a circuit connection substrate.
[0014] The utility model is further configured as follows: the shell is made of polycarbonate material.
[0015] By adopting the above technical solution, the shell has excellent thermal conductivity, high strength and high toughness.
[0016] In summary, the utility model has the following beneficial effects:
[0017] 1. The utility model first fixes the first heat sink in the shell and fits it with the shell, and then installs the second heat sink on the camera module. After the second heat sink is fixed, the camera module is placed in the shell. After the camera module is placed, the other side of the second heat sink will be in full contact with the first heat sink. The heat generated by the camera module when in use is easily transferred to the shell through the second heat sink and the first heat sink in turn for heat dissipation, which can improve the thermal conductivity of the module, so that the heat generated by the module is evenly and fully distributed outward, and the safety is high.
[0018] 2. The utility model lifts up the limit plate when the camera module reaches the bottom. After lifting up the limit plate, the limit plate is lowered along the threaded rod until it fits with the camera module. Then the nut is turned onto the threaded rod and tightened downward. The utility model has a limit function, avoids the module from shaking in the housing, prolongs the service life of the module, and is highly practical. BRIEF DESCRIPTION OF THE DRAWINGS
