DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0032] In the description of the present application, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise" and the like indicating orientations or positional relationships are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0033] like Figures 1 to 3 As shown, an embodiment of the present application provides a thermal imager 10, including a lens body 11, an eyepiece 12 and a mounting assembly 13.

[0034] The eyepiece 12 and the mounting assembly 13 are both mounted on the mirror body 11. Figure 4 The mounting assembly 13 includes a mounting frame 14 , a movement 15 and an objective lens 16 . The movement 15 and the objective lens 16 are both mounted on the mounting frame 14 , and the objective lens 16 is electrically connected to the movement 15 .

[0035] The objective lens 16 and the eyepiece 12 are respectively located at two opposite ends of the mirror body 11 , and the movement 15 is located inside the mirror body 11 .

[0036] Furthermore, the thermal imager further includes a distance measuring module 17 , which is mounted on the mirror body 11 and located on the outer side of the mirror body 11 .

[0037] With the above-mentioned thermal imager, the movement 15 is first installed on the mounting frame 14, and then the cables are connected and reinforced by dispensing glue. Next, the objective lens 16 is installed on the mounting frame 14 and the movement 15 is debugged. After the debugging is completed, the mounting assembly 13 is installed on the mirror body 11, and the movement 15 is located inside the mirror body 11. At the same time, the eyepiece 12 and the ranging module 17 can also be installed on the mirror body 11, and the eyepiece 12 and the objective lens 16 are located at both ends of the mirror body 11. Since the connection between the objective lens 16 and the movement 15 is performed outside the mirror body 11, there is no need to perform wiring inside the mirror body 11, which is convenient for assembly. The debugging between the movement 15 and the objective lens 16 can also be performed outside, which is also more convenient for debugging. In addition, the thermal imager can also measure distance through the ranging module 17, further improving the applicability of the thermal imager.

[0038] It should be explained that the debugging between the movement 15 and the objective lens 16 specifically refers to ensuring that the optical axis of the objective lens 16 and the detector center of the movement 15 are aligned through debugging after the objective lens 16 and the movement 15 are installed on the mounting frame 14.

[0039] Furthermore, in order to ensure the sealing of the thermal imager, a sealing ring 18 is provided at the objective lens 16 and the eyepiece 12. It should be noted that the mounting assembly 13 can be connected to the mirror body 11 through the objective lens 16, or can be connected to the mirror body 11 through the mounting frame 14 or the movement 15, which is not limited here. In addition, the above-mentioned components can be connected by screws.

[0040] In one embodiment, the thermal imager further includes a mounting member 19, which is mounted on the outer side of the mirror body 11, and the mounting member 19 and the outer side of the mirror body 11 enclose a mounting cavity, and the ranging module 17 is mounted in the mounting cavity. Further, the thermal imager further includes an adjustment component, which is connected to the mounting member 19, and partially extends into the mounting cavity and abuts against the ranging module 17, so as to adjust the position of the ranging module 17 in the radial direction, so that the optical axis of the ranging module 17 is parallel to the central axis of the mirror body 11, thereby ensuring the ranging accuracy.

[0041] It should be explained that the ranging module 17 is a laser ranging module, which has an optical axis. In this embodiment, the extension direction of the optical axis is the axial direction of the ranging module 17, and the corresponding ranging module 17 also has radial and circumferential directions perpendicular to the axial direction. The relationship between the radial, circumferential and axial directions is well known to those skilled in the art and will not be elaborated here.

[0042] Furthermore, the adjustment assembly includes a first adjustment member 20, a second adjustment member and a locking member. The first adjustment member 20, the second adjustment member and the fastener are all connected to the mounting member 19, and can partially extend into the mounting cavity and abut against the ranging module 17. The first adjustment member 20, the second adjustment member and the locking member can also adjust their positions radially to adjust the length of the extension into the mounting cavity, thereby ensuring that they abut against the ranging module 17 in the mounting cavity and adjusting the position of the ranging module 17.

[0043] Among them, the first adjusting member 20 and the second adjusting member can abut on the opposite sides of the ranging module 17 to cooperate with adjusting the position of the ranging module 17. The fastener is located circumferentially between the first adjusting member 20 and the second adjusting member so that the fastener can abut on the side of the ranging module 17 away from the mirror body 11 to cooperate with the first adjusting member 20 and the second adjusting member to fasten the ranging module 17.

[0044] It should be explained that, in this embodiment, the fastener abuts against the side of the ranging module 17 away from the mirror body 11, and can press the ranging module 17 against the outer side of the mirror body 11. The first adjusting member 20 and the second adjusting member abut against the opposite sides of the ranging module 17. Figure 3 In the illustrated embodiment, the first adjusting member 20 and the second adjusting member abut against the left and right sides of the ranging module 17, and the length of the first adjusting member 20 and the second adjusting member extending into the mounting cavity can be adjusted in the left-right direction, thereby adjusting the position of the ranging module 17 in the left-right direction, and adjusting the optical axis angle of the ranging module 17 to ensure that the optical axis of the ranging module 17 is parallel to the central axis of the mirror body 11.

[0045] In practical applications, the first adjusting member 20, the second adjusting member and the fastener are all screws. An elastic member or a flexible pad can be arranged between the ranging module 17 and the mirror body 11 in the installation cavity, so as to cooperate with the fastener to further adjust the position of the ranging module 17.

[0046] See also Figure 5 In one embodiment, the thermal imager further includes a red dot module 21, which is mounted on the outer side of the lens body 11. It should be noted that the accompanying drawings exemplarily show the distance measuring module 17 and the red dot module 21 separately, and do not limit the specific positions of the distance measuring module 17 and the red dot module 21. Specifically, when the red dot module 21 and the distance measuring module 17 are provided at the same time, the red dot module 21 and the distance measuring module 17 are arranged at intervals.

[0047] See also Figure 1 and Figure 3 In one embodiment, a power supply slot is also provided on the outer side of the mirror body 11, and the thermal imager further includes a battery and a sealing cover 22. The battery is installed in the power supply slot and can be electrically connected to the movement 15. The sealing cover 22 is connected to the power supply slot of the mirror body 11 to seal the power supply slot. In this way, when replacing the battery, it is only necessary to open the power supply slot and then replace it. After the replacement is completed, the power supply slot can be closed by the sealing cover 22, which is more convenient.

[0048] Preferably, the thermal imager further includes an anti-lost rope, which is connected between the sealing cover 22 and the mirror body 11 to prevent the sealing cover 22 from being lost.

[0049] In one embodiment, the thermal imager further includes a connecting plate 23, which is connected to the outer side of the lens body 11, and a connecting port is provided on the connecting plate 23, and a connector electrically connected to the movement 15 is provided at the connecting port, and the connector can be electrically connected to an external device, thereby realizing a wired connection between the movement 15 and the external device. Optionally, the connector is a type-c connector.

[0050] It is understandable that an opening communicating with the interior is provided on the outer side surface of the mirror body 11 , the connecting plate 23 is connected to the opening on the outer side surface of the mirror body 11 , and the connector connected to the movement 15 is provided at the connecting port of the connecting plate 23 .

[0051] Furthermore, the thermal imager further comprises a sealing plug 24, which is connected to the connection port of the connection plate 23 to seal the connection port during use of the thermal imager to prevent external impurities or water vapor from entering. When a wired connection with an external device is required, the sealing plug 24 can be removed.

[0052] In one embodiment, a plurality of control buttons 25 are disposed on the outer side of the lens body 11, and each control button 25 is electrically connected to the movement 15 to implement control actions. Specifically, the plurality of control buttons 25 include but are not limited to power on / off buttons, focus adjustment buttons, and function buttons.

[0053] In one embodiment, the outer side surface of the lens body 11 is covered with a flexible rubber pad 26, and the flexible rubber pad 26 is wrapped around the red dot module 21 to fix the red dot module 21 to the outer side surface of the lens body 11 and ensure that the red dot module 21 is at least partially exposed so that the red dot module 21 can be used normally.

[0054] At the connection plate 23 and the sealing cover 22, the flexible rubber pad 26 is provided with corresponding windows to expose the connection plate 23 and the sealing cover 22. Of course, the flexible rubber pad 26 can also be covered on the outside of the mounting member 19 to further improve the comfort of use. It should also be noted that Figure 1 and Figure 5 Only the positions of the mirror body 11, the mounting part 19 and the red dot module 21 are shown, but their surfaces are covered with a flexible rubber pad 26.

[0055] In one embodiment, wrist strap buckles 27 are provided at both ends of the lens body 11 to connect a wrist strap, thereby further facilitating use and preventing the thermal imager from falling during use.

[0056] Based on the above embodiments, the thermal imager provided by the present application has at least the following advantages:

[0057] 1. The movement 15 and the objective lens 16 are mounted on the mounting frame 14 to form the mounting assembly 13, and then the lens body 11 is installed. The cables can be arranged outside in advance, which is more convenient for assembly;

[0058] 2. A distance measuring module 17 and a red dot module 21 are provided on the outer side of the mirror body 11 to improve the functionality of the thermal imager and thus improve the applicability of the thermal imager;

[0059] 3. The position of the distance measuring module 17 can be adjusted by adjusting the components to ensure that the distance measuring optical axis of the distance measuring module 17 is parallel to the central axis of the mirror body 11, thereby ensuring the accuracy of distance measurement.

[0060] Although the embodiments of the present application have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present application, and that the scope of the present application is defined by the appended claims and their equivalents.
