[0031] A sliding sleeve 31 is arranged at the outermost layer of the protection carrier 3, and the outer wall of the sliding sleeve 31 is slidably connected with the inner wall of the lifting cavity;

[0032] The vibration-damping layer is arranged on the inner side of the sliding sleeve 31, and the vibration-damping layer includes a connecting sleeve 32, a vibration-damping jacket 33 made of a vibration-damping material, and a first vibration-damping jacket 34 made of a vibration-damping material. The vibration-damping jacket 33 is arranged between the first vibration-damping jacket 34 and the connecting sleeve 32. The vibration-damping jacket 33 is in the shape of a honeycomb mesh. The two ends of each honeycomb mesh inside the vibration-damping jacket 33 are respectively fitted and abutted against the first vibration-damping jacket 34 and the connecting sleeve 32. The honeycomb mesh is filled with an inert gas. The first vibration-damping jacket 34 is fixedly connected to the inner wall of the sliding sleeve 31, and the connecting sleeve 32 is detachably connected to the high-precision camera 6.

[0033] Specifically, in this embodiment, the model of the high-precision camera 6 can be JSX-PT-248, the model of the photosensitive chip used by the high-precision camera 6 is IMX686-FAJH5-F, the pixel of the high-precision camera 6 is 9248*6944, the material of the first vibration-damping sleeve 34 can be EVA plastic, and the material of the vibration-damping sleeve 33 can be rubber.

[0034] In this embodiment, a vibration-damping interlayer is arranged in the protective carrier 3, and a vibration-damping jacket 33 made of vibration-damping material and a first vibration-damping jacket 34 made of vibration-damping material are used to effectively reduce the horizontal vibration generated by the high-precision camera 6 during the lifting process. At the same time, in addition to using the inert gas in the honeycomb mesh and the material of the vibration-damping jacket 33 to effectively reduce vibration, the honeycomb mesh vibration-damping jacket 33 can also provide a certain structural strength to achieve support.

[0035] Preferably, the inner wall of the connecting sleeve 32 is provided with an internal thread, the outer wall of the bottom end of the high-precision camera 6 is provided with an external thread, and the high-precision camera 6 is screwed into the connecting sleeve 32 .

[0036] Specifically, in the present embodiment, the connecting sleeve 32 is threadedly connected to the high-precision camera 6, thereby achieving convenient and fast installation and disassembly, and facilitating installation and maintenance.

[0037] Preferably, the vibration-damping layer also includes a second vibration-damping sleeve 35 made of vibration-damping material, which is arranged between the connecting sleeve 32 and the vibration-damping jacket 33, and the two ends of each honeycomb mesh inside the vibration-damping jacket 33 are respectively fitted and abutted against the first vibration-damping sleeve 34 and the second vibration-damping sleeve 35.

[0038] Specifically, in this embodiment, a second vibration-damping sleeve 35 made of a vibration-damping material is arranged between the connecting sleeve 32 and the vibration-damping sleeve 33. The material of the second vibration-damping sleeve 35 can be EVA material, so that secondary buffering and vibration reduction are achieved between the connecting sleeve 32 and the vibration-damping sleeve 33, thereby further improving the vibration-damping effect.

[0039] Working principle of embodiment 1:

[0040] When the coil 4 is energized, an induced current is generated on the coil 4. The induced current generates a repulsive force in the magnetic field composed of four magnets, pushing the high-precision camera 6 to rise in the lifting cavity to achieve focusing. The magnitude of the induced current can be controlled by an RC drive circuit. During the lifting and focusing process of the high-precision camera 6, vibrations may be generated in the horizontal direction. The vibrations are transmitted to the second vibration-damping sleeve 35, causing the second vibration-damping sleeve 35 to deform and absorb a part, and then transmitted to each honeycomb mesh in the vibration-damping jacket 33. The inert gas in each honeycomb mesh absorbs a part, and then the honeycomb mesh vibration-damping jacket 33 deforms and absorbs a part, and finally transmitted to the first vibration-damping sleeve 34, causing the first vibration-damping sleeve 34 to deform and absorb a part. Therefore, the vibration in the horizontal direction will undergo four vibration-damping absorptions, thereby being weakened to have almost no effect on the high-precision camera 6, so that the vibration reduction performance and use stability are significantly improved.

[0041] Embodiment 2 is the second embodiment of the present invention. Different from the previous embodiment, this embodiment provides a buffer gasket 7, which can improve the vibration reduction performance of the high-precision camera 6 in the vertical direction. In this embodiment, buffer gaskets 7 are provided on the top inner wall and the bottom inner wall of the lifting cavity, and the buffer gaskets 7 are filled with inert gas.

[0042] Specifically, in this embodiment, the buffer gasket 7 may be made of a silicone material, and the interior of the silicone material is filled with nitrogen.

[0043] Working principle of embodiment 2:

[0044] When the induced current generates a repulsive force and pushes the high-precision camera 6 to rise and fall in the lifting chamber, the high-precision camera 6 may touch the top inner wall and the bottom inner wall inside the lifting chamber, thereby generating vibration in the vertical direction. By providing a buffer gasket 7 at the top inner wall and the bottom inner wall inside the lifting chamber, and the buffer gasket 7 is filled with an inert gas, the high-precision camera 6 touches the buffer gasket 7 inside the lifting chamber without directly contacting the top inner wall and the bottom inner wall thereof. The buffer gasket 7 is deformed and the nitrogen inside is used to significantly reduce vibration. Therefore, this embodiment significantly improves the vibration reduction performance of the high-precision camera 6 in the vertical direction.

[0045] Example 3, reference Figure 4, which is the third embodiment of the present invention. Different from the previous embodiment, this embodiment provides a heat sink 8, which can improve the heat dissipation performance of the high-precision camera 6. In this embodiment, an annular heat sink 8 is provided at the upper end of the metal shell 2, and the interior of the heat sink 8 is provided with an annular flow cavity, which is connected to the air outlet end of an air blowing device through an air outlet duct 9. The inner side of the heat sink 8 is inclined toward the outer side wall of the high-precision camera 6, and a plurality of air outlet holes 10 are evenly opened on the inner side of the heat sink 8. When the air blowing device is running, the air outlet holes 10 blow air toward the outer side wall of the high-precision camera 6 and the lifting cavity.

[0046] Working principle of embodiment 3:

[0047] The inner side of the heat sink 8 is inclined toward the outer wall of the high-precision camera 6, so that when the blower is running, the cold air generated by the blower passes through the air outlet duct 9 and the circulation cavity in turn, and then is blown out from the air outlet holes 10 of the heat sink 8. It can blow directly toward the outer wall of the high-precision camera 6 and the lifting cavity to reduce the temperature of the outer wall of the high-precision camera 6, thereby improving the heat dissipation performance of the high-precision camera 6, and at the same time blow into the lifting cavity to reduce the temperature inside the lifting cavity.

[0048] Preferably, the inner side of the heat sink 8 is inclined toward the outer side wall of the high-precision camera 6 at an angle ranging from 30° to 60°.

[0049] Specifically, in the present embodiment, when the angle range of the inner side of the heat sink 8 tilting toward the outer side wall of the high-precision camera 6 is between 30°-60°, the effect of directly blowing air to the outer side wall of the high-precision camera 6 is better, and the blowing cooling effect is best when the angle range of the inner side of the heat sink 8 tilting toward the outer side wall of the high-precision camera 6 is 45°.

[0050] Preferably, a plurality of heat dissipation holes 11 are evenly formed on the outer edge of the bottom end of the metal shell 2 .

[0051] Specifically, in this embodiment, after a plurality of heat dissipation holes 11 are evenly opened on the outer edge of the bottom end of the metal shell 2, the wind blown out from the air outlets of the heat sink 8 can pass through the lifting cavity, and then blow out from the heat dissipation holes 11 to form a complete air duct, thereby improving the heat dissipation effect inside the lifting cavity.

[0052] Preferably, each air outlet hole 10 and each heat dissipation hole 11 is in a strip shape, and each air outlet hole 10 and each heat dissipation hole 11 is inclined in the same direction.

[0053] Specifically, in this embodiment, when the air outlet holes 10 and the heat dissipation holes 11 are inclined in the same direction, the generated wind flow will rotate to form a rotating airflow, and the flow rate of the rotating airflow will increase due to the rotation, thereby improving the heat dissipation effect inside the lifting cavity.

[0054] Preferably, the inclination angle between each air outlet 10 and each heat dissipation hole 11 is in the range of 40°-50°.

[0055] Specifically, in this embodiment, when the inclination angle range of each air outlet hole 10 and each heat dissipation hole 11 is 45°, the flow rate of the rotating airflow is the fastest, and the heat dissipation effect on the inside of the lifting cavity is the best.

All technical solutions under the idea of ​​the utility model belong to the protection scope of the utility model. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the utility model should also be regarded as the protection scope of the utility model.
