Specific implementation manner

[0027] The core of the present utility model is to provide a calibratable ranging device that can adjust the angle of the ranging module to achieve adjustable imaging center of the ranging module.

[0028] In order to enable those skilled in the art to better understand the technical solution of the present utility model, the calibratable ranging device of the present utility model will be introduced and described in detail below in conjunction with the accompanying drawings and specific implementation manners.

[0029] The present utility model provides a calibratable ranging device, which includes structures such as a ranging module 2, an adapter assembly 3, and a first adjustment assembly 4, etc.; this ranging device can be used in mutual matching with an infrared imaging module 1 to realize the combined use of infrared imaging and laser ranging. The infrared imaging module 1 can also be replaced by other structures to play a role of positioning and support. The embodiments of the present utility model are introduced and described by taking the combined use of the ranging device and the infrared imaging module 1 as an example, in combination with Figure 1 , Figure 2 shown, in which the infrared imaging module 1 is used to realize infrared imaging, and the ranging module 2 is used to realize laser ranging. Figure 2 Among them, the dotted line A represents the imaging center line of the infrared imaging module 1, and the dotted line B represents the imaging center line of the ranging module 2; both infrared imaging and laser ranging are performed for detection towards the same side. In the embodiment shown in the accompanying drawings of the present utility model, the ranging module 2 is arranged above the infrared imaging module 1, but the present utility model is not limited to this. The ranging module 2 can also be arranged on the side or below the infrared imaging module 1, and correspondingly, the adapter assembly 3 also makes corresponding changes.

[0030] The adapter assembly 3 is installed on the infrared imaging module 1. After the adapter assembly 3 is installed in place, it is fixedly arranged relative to the infrared imaging module 1. The adapter assembly 3 plays a role in support and protection. The ranging module 2 is rotatably installed on the adapter assembly 3;

[0031] The first adjustment assembly 4 includes an elastic member 41 and a first ejector rod 42. The elastic member 41 and the first ejector rod 42 are arranged oppositely and are respectively located at two opposite sides of the ranging module 2. As Figure 1 shown in the embodiment, the elastic member 41 is located below the ranging module 2, and the first ejector rod 42 is located above the ranging module 2. The elastic member 41 is located between the ranging module 2 and the infrared imaging module 1. The elastic member 41 and the first ejector rod 42 are respectively in contact with the ranging module 2. The elastic member 41 is used to contact the ranging module 2 to provide elastic force. The first ejector rod 42 is movably installed on the adapter assembly 3. The first ejector rod 42 can approach or move away from the ranging module 2, so as to press or loosen the ranging module 2; the first ejector rod 42 is used to apply a tightening force to the ranging module 2, so that the ranging module 2 squeezes the elastic member 41, causing the elastic member 41 to undergo elastic deformation. The direction of the elastic force is towards the first ejector rod 42; through the elastic deformation of the elastic member 41, the ranging module 2 is always limited between the elastic member 41 and the first ejector rod 42. When the first ejector rod 42 moves towards the ranging module 2, the ranging module 2 further squeezes the elastic member 41, and the degree of deformation of the elastic member 41 increases; when the first ejector rod 42 moves away from the ranging module 2, the ranging module 2 reduces the extrusion of the elastic member 41, and the degree of deformation of the elastic member 41 decreases; the line connecting the elastic member 41 and the first ejector rod 42 does not coincide with the rotation axis of the ranging module 2. When the first ejector rod 42 adjusts the ranging module 2, the ranging module 2 can be rotated around the rotation axis to realize the rotational adjustment of the ranging module 2.

[0032] The utility model utilizes the mutual cooperation of the elastic member 41 and the first ejector rod 42 to change the detection angle of the ranging module 2. By using the elastic deformation generated by the elastic member 41, it can be adaptively cooperated with the first ejector rod 42. The elastic member 41 and the first ejector rod 42 are always in contact and press the ranging module 2. When the first ejector rod 42 moves, the ranging module 2 can be rotated around the rotation axis to adjust the angle. When applied to an infrared imaging device, the ranging module 2 can be made to coincide with the center of the infrared imaging module 1, realizing that the laser ranging indication position and the infrared thermal imaging center are adjustable, ensuring that both the ranging module 2 and the infrared imaging module 1 can aim at the same position of the object to be measured during detection.

[0033] On the basis of the above scheme, the elastic member 41 adopted by the utility model is an elastic sheet. Combined with Figure 3As shown, both ends of the elastic sheet are respectively connected to the card slots 31 provided on the adapter assembly 3. Both ends of the elastic sheet are respectively inserted into the two card slots 31, and the distance between both ends of the elastic sheet is limited by the two card slots 31. The middle part of the elastic member 41 arches towards the distance measuring module 2, and through the elastic deformation generated when the elastic sheet is squeezed, the elastic force of the distance measuring module 2 is realized. In addition to setting the elastic sheet, an elastic structure such as a spiral spring can also be used.

[0034] Combined with Figure 1 As shown, the distance measuring module 2 is rotatably connected to the adapter assembly 3 through two coaxial mounting pivot screws 43. A pivot screw 43 is respectively mounted on each of the opposite sides of the distance measuring module 2. The pivot screw 43 serves as a pivot, and each pivot screw 43 matches with a side wall of the adapter assembly 3, enabling the distance measuring module 2 to rotate around the connection line of the two pivot screws 43.

[0035] Combined with Figure 1 As shown, the adapter assembly 3 includes an adapter housing 301 and a mounting bracket 302. The adapter housing 301 is a hollow housing structure. The distance measuring module 2 is in the form of a vertically arranged plate structure. The adapter housing 301 and the mounting bracket 302 jointly enclose a shielding space. The adapter housing 301, the mounting bracket 302, and the infrared imaging module 1 jointly form a cavity for accommodating the distance measuring module 2, and the distance measuring module 2 can be adjusted within this cavity.

[0036] Combined with Figure 1 As shown, two support ear plates are provided on the mounting bracket 302, and the distance measuring module 2 is rotatably mounted on the ear plates of the mounting bracket 302. The bottom of the mounting bracket 302 is assembled to the infrared imaging module 1. The adapter housing 301 is directly assembled to the infrared imaging module 1 and is docked to the mounting bracket 302. Both the adapter housing 301 and the mounting bracket 302 are connected to the housing of the infrared imaging module 1. The entire adapter assembly 3 is composed of two split structures, namely the adapter housing 301 and the mounting bracket 302, which can be conveniently installed and combined. During assembly, first install the distance measuring module 2 on the mounting bracket 302 through the pivot screws 43, then install the mounting bracket 302 on the infrared imaging module 1, and finally install the adapter housing 301 on the infrared imaging module 1.

[0037] Combined with Figure 1 、 Figure 4 As shown, the pivot of the distance measuring module 2 is located on the side close to the distance measuring end, and the first adjustment assembly 4 is located on the side far from the distance measuring end. The first adjustment assembly 4 is far from the pivot of the distance measuring module 2, and can more easily realize the rotational adjustment of the distance measuring module 2, avoiding directly applying pressure to the pivot of the distance measuring module 2.

[0038] Furthermore, the calibratable distance measuring device of the present utility model further includes a second adjustment assembly 5. Combined with Figure 1 、 Figure 4As shown, the second adjustment component 5 includes a first top screw 51 and a second top screw 52 respectively threadedly mounted on two opposite side walls of the adapter component 3, the first top screw 51 and the second top screw 52 are arranged opposite to each other, and the first top screw 51 and the second top screw 52 are respectively pressed against the side walls of the ranging module 2; the adjustment direction of the second adjustment component 5 is perpendicular to the adjustment direction of the first adjustment component 4, Figure 1 In the embodiment shown, the first top screw 51 and the second top screw 52 are used to achieve left and right swing adjustment, and the elastic member 41 and the first top rod 42 cooperate with each other to achieve up and down pitch adjustment. The first adjustment component 4 and the second adjustment component 5 cooperate with each other to achieve two-dimensional rotation adjustment, and the detection direction of the ranging module 2 can be adjusted in more dimensions.

[0039] It should be noted that the adjustment of the first top screw 51 and the second top screw 52 is achieved by cooperating with each other in advance and retreat, that is, when the first top screw 51 is close to the ranging module 2, the second top screw 52 is away from the ranging module 2, or when the first top screw 51 is away from the ranging module 2, the second top screw 52 is close to the ranging module 2; the adjustment range of the first top screw 51 and the second top screw 52 is small, and the left and right swing adjustment can be achieved only by the deformation of the ranging module 2 at the position of the rotating screw 43 and the elastic deformation of the entire ranging module 2 itself, and there is no need to set a corresponding shaft structure for the first top screw 51 and the second top screw 52.

[0040] Combination Figure 1 In order to reduce wear, a metal stress block 21 is set on the side wall of the ranging module 2. The metal stress block 21 is a columnar structure protruding from the outer surface of the ranging module 2. The first top screw 51 and the second top screw 52 respectively contact and press against the metal stress block 21, thereby reducing the wear on the ranging module 2 and reducing the deformation of the ranging module 2 to ensure the adjustment accuracy.

[0041] The second adjustment component 5 is located at a side away from the distance measuring end of the distance measuring module 2 , so as to reduce the pressure directly on the position of the rotating screw 43 .

[0042] Combination Figure 4 As shown, the ends of the rotating shaft screw 43 in the present invention are all spherical surfaces, which are used to contact and match with the spherical groove set in the ranging module 2 to form a rotational fit. In addition to realizing the pitch adjustment of the elastic member 41 and the first top rod 42, the left and right swing adjustment of the first top screw 51 and the second top screw 52 can also be realized.

[0043] The utility model also provides an infrared thermal imaging device, including the above-mentioned calibrable distance measuring device, and also including an infrared imaging module 1 assembled with the calibrable distance measuring device, wherein the infrared imaging module 1 is used to realize infrared imaging, the infrared imaging module 1 serves as a supporting structure of the calibrable distance measuring device, the adapter component 3 is installed on the infrared imaging module 1, and the distance measuring module 2 can realize angle adjustment, thereby realizing that the imaging centers of the infrared imaging module 1 and the distance measuring module 2 are adjustable, and the imaging centers of the two are made to coincide during measurement.

[0044] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
