Referring to fig. 1 to fig. 3, the present invention provides a thermal imager 100, which includes an optical lens 10, an infrared detector 20 and a light processing device 30, wherein the infrared detector 20 is located on the image side of the optical lens 10 and is used for receiving infrared radiation passing through the optical lens 10, and the light processing device 30 is located between the optical lens 10 and the infrared detector 20.

In this way, the light processing device 30 is arranged between the optical lens 10 and the infrared detector 20, so that light emitted by the optical lens 10 can be processed by the light processing device 30, and infrared radiation signals of the light are converted and imaged by the infrared detector 20, and thus the light in the thermal imager 100 can be processed, the requirements of different users can be met, and the functions of the thermal imager 100 are richer.

Referring to fig. 4 to 6, in some embodiments, the light processing device 30 includes a driving actuator 31 and a functional structure 32. The driving steering engine 31 comprises a steering engine main body 311 and an output shaft 312 arranged on the steering engine main body 311, the output shaft 312 is used for rotating under the driving of the steering engine main body 311, the functional structure 32 comprises a connecting arm 321 and a main body part 322 connected to the connecting arm 321, an installation part 3211 is arranged at one end, far away from the main body part 322, of the connecting arm 321, a shaft hole 32111 is formed in the installation part 3211, the shaft hole 32111 is sleeved on the output shaft 312, and the main body part 322 is used for rotating under the driving of the output shaft 312 so as to switch between a working state and an initial state.

The operating state is a state in which the main body 322 blocks at least part of the light emitted through the optical lens 10, and the initial state is a state in which the main body 322 does not block the light emitted through the optical lens 10.

Like this, through setting up output shaft 312 at drive steering wheel 31, and output shaft 312 rotatable coupling in the shaft hole 32111 of functional structure 32, can make functional structure 32 switch between operating condition and initial condition to can realize thermal imager 100's conventional formation of image, can handle thermal imager 100's light again (for example shelter from some or all light), with the thermal imaging that realizes different demands, and then richen thermal imager 100's function.

Meanwhile, the driving steering engine 31 is arranged, so that the position accuracy of the moved functional structure 32 can be improved, the rotation angle of the output shaft 312 can be adjusted according to actual requirements, the included angle of the functional structure 32 in the initial state and the working state can be adjusted, the movement amplitude of the driving steering engine 31 can be adjusted by the light processing device 30 according to the structure of the thermal imager 100 (such as the relative position of the optical lens 10 and the size of the internal space of the thermal imager 100), the relative position of the functional structure 32 and the steering engine main body 311 can be adjusted, the light processing device 30 can be suitable for different thermal imagers 100, and the application range of the light processing device 30 is further expanded.

Alternatively, the connection manner of the shaft hole 32111 and the output shaft 312 may be any one of a locking connection, an interference connection, or a threaded connection, so that the connection between the shaft hole 32111 and the output shaft 312 is more reliable.

In one example, the shaft hole 32111 and the output shaft 312 are connected by a locking connection. Specifically, the light processing device 30 further includes a stopper 33, the stopper 33 is disposed through the shaft hole 32111 of the mounting portion 3211 and connected to the output shaft 312, and the stopper 33 is used for limiting the shaft hole 32111 to be separated from the output shaft 312 along the axial direction of the output shaft 312. Thus, axial fixation of the shaft hole 32111 and the output shaft 312 can be realized, and separation of the functional structure 32 from the driving steering engine 31 due to separation of the output shaft 312 from the shaft hole 32111 is avoided, so that the connection reliability of the functional structure 32 and the driving steering engine 31 is improved.

Further, the output shaft 312 is provided with a threaded hole along the axial direction thereof, and the aperture of the threaded hole and the aperture of the shaft hole 32111, the mounting portion 3211 is provided with a first mounting groove and a second mounting groove along the central line direction of the shaft hole 32111, the first mounting groove and the second mounting groove are communicated with the shaft hole 32111, the opening directions of the first mounting groove and the second mounting groove are opposite, at least part of the output shaft 312 extends into the first mounting groove, so that the threaded hole and the shaft hole 32111 are correspondingly arranged, and the limiting member 33 is used for extending into the shaft hole 32111 via the second mounting groove and is in threaded connection with the threaded hole.

The size of the thermal imager 100 along the axis direction of the output shaft 312 can be reduced by the arrangement of the first mounting groove and the second mounting groove, the small-size light and thin design of the thermal imager 100 is facilitated, meanwhile, the head of the limiting part 33 can be hidden in the second mounting groove of the mounting portion 3211, on one hand, the head of the exposed limiting part 33 can be prevented from interfering with other structures of the thermal imager 100, so that the mounting of other structures is facilitated, and on the other hand, the attractiveness of the connecting position of the shaft hole 32111 and the output shaft 312 can be improved.

Alternatively, the limiting member 33 may be, but is not limited to, any one of a screw, a bolt or a threaded rod, so that the limiting member 33 can be in threaded connection with the threaded hole of the output shaft 312, thereby stably connecting the shaft hole 32111 with the output shaft 312.

Optionally, a notch 32112 is provided on the mounting portion 3211, the notch 32112 is located at the periphery of the shaft hole 32111 and is communicated with the shaft hole 32111, both sides of the mounting portion 3211 corresponding to the notch 32112 are provided with a locking portion 32113, each locking portion 32113 is located at the periphery of the shaft hole 32111, and each locking portion 32113 is provided with a first mounting hole 32113a communicated with each other, and the two first mounting holes 32113a are used for a fastening member to pass through, so that the shaft hole 32111 is locked and connected to the output shaft 312 along its own circumferential direction.

Like this, the setting that increases breach 32112 can improve the size surplus of shaft hole 32111 to be favorable to the equipment cooperation of shaft hole 32111 and output shaft 312, can effectively avoid leading to the unable condition of assembling of the two because of dimensional tolerance, thereby be favorable to the equipment and the dismantlement of output shaft 312 and shaft hole 32111. Meanwhile, a fastener is inserted into the first mounting hole 32113a to connect the two locking portions 32113, so that the distance between the two locking portions 32113 (i.e., the size of the gap 32112) can be reduced, and the size of the shaft hole 32111 can be reduced, thereby locking and connecting the output shaft 312 and the shaft hole 32111 in the circumferential direction.

It can be seen that, through the action of the limiting member 33 and the locking portion 32113, the output shaft 312 and the shaft hole 32111 can be fixed in the circumferential direction and the axial direction of the output shaft 312 and the shaft hole 32111, so that the output shaft 312 and the shaft hole 32111 can be stably connected, the connection reliability between the functional structure 32 and the driving steering engine 31 is improved, and the normal use of the light processing device 30 is ensured.

Alternatively, the fastening member may be, but is not limited to, any one of a screw, a bolt, or a threaded rod, and the first mounting hole 32113a may be a threaded hole, and is screwed to stably connect the locking portions 32113 at two sides of the gap 32112, so as to lock and connect the shaft hole 32111 and the output shaft 312 in the circumferential direction.

In another example, the shaft hole 32111 is connected to the output shaft 312 by a screw connection. Specifically, the shaft hole 32111 is provided with an internal thread, and the output shaft 312 is provided with an external thread, which are engaged with each other by a thread to fix the shaft hole 32111 to the output shaft 312. Therefore, the connection mode of the shaft hole 32111 and the output shaft 312 is simpler and more convenient, which is beneficial to reducing the number of parts of the thermal imager 100.

Alternatively, considering that the shaft hole 32111 and the output shaft 312 are sleeved, the outer peripheral surface of the output shaft 312 may be provided with a non-slip portion, such as knurling or embossing. Accordingly, the frictional force on the outer peripheral surface of the output shaft 312 can be increased to achieve an anti-slip function, and the connection between the shaft hole 32111 and the output shaft 312 can be stabilized.

In some embodiments, the functional structure 32 further includes a position detection module 323, the position detection module 323 is disposed at an end of the connecting arm 321 where the shaft hole 32111 is disposed, and the position detection module 323 is located outside the shaft hole 32111, and the position detection module 323 is configured to detect a position of the functional structure 32.

In this way, whether the position of the functional structure 32 moves in place is detected by the position detection module 323, so as to ensure that the main body 322 shields at least part of the light emitted by the optical lens 10 in the working state, or the main body 322 does not shield the light emitted by the optical lens 10 in the initial state, so as to ensure the working effect of the functional structure 32, so as to realize processing of the light in the thermal imager 100, and further to ensure that the thermal imager 100 can meet the requirements of different users, thereby enriching the functions of the thermal imager 100.

Alternatively, the position detection module 323 may be, but is not limited to, any one of a photoelectric switch, an optical coupler, or a hall sensor, so that the size and weight of the position detection module 323 are small, thereby being capable of following the movement of the connecting arm 321 and detecting the position of the feedback connecting arm 321 in real time.

In some embodiments, the main body 322 includes a barrier structure or a filter structure to improve the uniformity of the thermal image, or to reduce the radiation energy of the light or filter the wavelength band.

As an alternative implementation, when the main body portion 322 includes the optical filter structure, in an operating state, the main body portion 322 is used for blocking part of the light emitted through the optical lens 10.

Thus, when the main body 322 is in the operating state, the optical filter structure can be used to shield part of the light emitted by the optical lens 10, so that part of the light passes through the optical filter structure, and therefore, on one hand, the radiation energy of the light can be reduced through the optical filter structure, so as to filter high temperature, and the thermal imager 100 is switched to the high-temperature operating state, so that the thermal imager 100 can detect or observe higher temperature, and further, the thermal imager 100 is protected from being damaged by high temperature. On the other hand, the filter structure can cut off a specific wave band and filter an interference source so as to filter out unnecessary light and realize thermal imaging of specified wavelength.

Furthermore, a second mounting hole 3221 is disposed on the main body portion 322, and the optical filter structure is disposed in the second mounting hole 3221, so that light can be filtered through the optical filter structure in the second mounting hole 3221, and the connection between the optical filter structure and the main body portion 322 can be more stable and reliable.

Furthermore, the connection between the filter structure and the second mounting hole 3221 may be any one of an adhesive connection, a snap connection, or a locking connection.

In one example, the filter structure is connected to the second mounting hole 3221 by adhesion. Specifically, any one of an adhesive, a back adhesive, and a double-sided adhesive is coated on the inner wall surface of the second mounting hole 3221 or the outer periphery of the optical filter structure, and the optical filter structure is attached to the inner wall surface of the second mounting hole 3221, so that the optical filter structure is adhered inside the second mounting hole 3221.

In another example, the filter structure is connected to the second mounting hole 3221 by a snap-fit connection. Specifically, the inner wall surface of the second mounting hole 3221 is provided with a mounting groove along the circumferential direction of the second mounting hole 3221, and the outer circumferential surface of the optical filter structure is clamped in the mounting groove, so that the optical filter structure is clamped in the second mounting hole 3221.

Further, the thickness of the connection arm 321 may be 1mm-3mm, for example, 1.5mm, 2mm or 2.5mm, so that the connection arm 321 has sufficient strength to support the filter structure.

Referring to fig. 7 and 8, as another alternative embodiment, when the main body portion 322 includes a blocking structure, in an operating state, the main body portion 322 is used for blocking light emitted through the optical lens 10.

Thus, when the main body 322 is in the operating state, the blocking piece structure can be used to block all or most of the light rays emitted by the optical lens 10, and the thermal imager 100 is subjected to non-uniformity correction through the blocking piece structure, so that the imaging picture of the thermal imager 100 is more uniform, ghost images and dead spots are eliminated, and the imaging quality is improved.

Optionally, the surface color of the main body portion 322 may be black, so as to better absorb light, reduce reflection, and facilitate absorption of light by the barrier structure, thereby facilitating uniformity correction of the thermal imager 100.

Further, the thickness of the main body 322 along the center line of the shaft hole 32111 is 0.1mm to 0.5mm, for example, 0.2mm, 0.3mm, or 0.4mm. In this way, the thickness of the main body portion 322 is thin, which is beneficial to the absorption of the main body portion 322 to heat, so that the overall temperature distribution of the main body portion 322 is more uniform, which is beneficial to the non-uniformity correction of the thermal imager 100, thereby improving the image uniformity of thermal imaging and further improving the imaging quality of the thermal imager 100.

Alternatively, considering that the functional structure 32 is connected with the output shaft 312 through the shaft hole 32111, and the main body portion 322 is connected to an end far from the shaft hole 32111 through the connecting arm 321, based on which the thickness of the end of the connecting arm 321 close to the shaft hole 32111 in the direction of the centerline of the shaft hole 32111 is greater than that of the main body portion 322, preferably, the thickness ratio of the connecting arm 321 to the main body portion 322 is 3. Therefore, the structural strength of the connecting arm 321 can be enhanced, and the connection between the functional structure 32 and the driving steering engine 31 is more stable and reliable.

Referring to fig. 9 and 10, in some embodiments, the thermal imager 100 may include one or more light processing devices 30, and when the thermal imager 100 includes one light processing device 30, the main body 322 may be an optical filter structure or a baffle structure. When the thermal imager 100 includes a plurality of light processing devices 30, for example, two light processing devices 30, the main body portions 322 of the two light processing devices 30 may be both of a barrier structure or both of a filter structure, or the main body portion 322 of one of the two light processing devices 30 may be a barrier structure and the main body portion 322 of the other one may be a filter structure, so that the number and the type of the light processing devices 30 can be selected according to actual situations, and thus the thermal imager 100 can simultaneously achieve non-uniformity correction of the thermal imager 100 and radiation energy reduction or band filtering of light.

In the following description, it will be exemplified that the main body portions 322 of the two light processing devices 30 included in the thermal imager 100 may respectively include a blocking sheet structure and a filter structure, the two main body portions 322 are disposed between the optical lens 10 and the infrared detector 20 at intervals, and the central positions of the two main body portions 322 along the central line direction of the shaft hole 32111 are the same in the working state.

Thus, when one of the functional structures 32 is moved to the operating state, the thermal imager 100 may enable non-uniformity correction of the thermal imager 100, or the thermal imager 100 may enable radiation energy reduction or band filtering of light. When the two functional structures 32 move to the working state at the same time, the thermal imager 100 can simultaneously achieve non-uniformity correction of the thermal imager 100 and radiation energy reduction or band filtering of light.

It is understood that, in the working state, one of the two main body portions 322 is located at a side close to the optical lens 10, and the other is located at a side far from the optical lens 10, and the front and back positions of the two main body portions can be arranged according to actual requirements, which is not limited herein.

Preferably, the material of the functional structure 32 may be metal or plastic, for example, any one of aluminum alloy, copper or stainless steel, so as to improve the connection stability between the functional structure 32 and the output shaft 312, and facilitate the reciprocating motion of the functional structure 32.

As can be seen from the foregoing, when the main body portion 322 of the functional structure 32 includes the blocking piece structure, the surface color of the main body portion 322 is black, and based on this, the material of the functional structure 32 can be an aluminum magnesium alloy, so that on one hand, the weight of the functional structure 32 can be reduced, and on the other hand, the surface treatment of the functional structure 32 (for example, the surface of the main body portion 322 is converted into black by an anodic oxidation method) can be facilitated, so as to improve the light treatment effect of the main body portion 322.

Referring to fig. 11 to 13, in some embodiments, the light processing device 30 further includes a positioning fixture 40, and the positioning fixture 40 is detachably connected to the steering engine main body 311 and the connecting arm 321 in an initial state to position a connection position between the shaft hole 32111 of the connecting arm 321 and the output shaft 312.
