[0024] The portable thermal imager provided by the utility model has the following beneficial effects:

[0025] When the first body and the second body are not folded, that is, when the portable thermal imager is unfolded, it has two states. One is that the first body and the second body are close to and abut against each other, and the other is that the first body and the second body are far away from each other. In these two states, by using the first buckle and the second buckle to be respectively clamped with both ends of the external support device, the portable thermal imager can be fixed to the external support device, making the portable thermal imager a thermal imaging system of the external support device, facilitating the use of the external support device as a detection tool to monitor the temperature of the target object at any time.

Specific implementation manners

[0039] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0040] The core of the present invention is to provide a portable thermal imager, which is small in size and convenient to carry. Another core of the present invention is to provide a thermal imager system including the above portable thermal imager, and its portable thermal imager is convenient to carry.

[0041] Please refer to Figure 1 、 Figure 2 and Figure 3 , an embodiment of the present invention provides a portable thermal imager, including a first body 1 and a second body 2. The first body 1 is provided with a first buckle position 11; the second body 2 is provided with a second buckle position 21; the first body 1 and the second body 2 are movably connected, and the first body 1 and the second body 2 can approach or move away from each other along a first direction. When the first body 1 and the second body 2 approach, at least one of them can be flipped and folded so that the first body 1 and the second body 2 at least partially overlap. When the first body 1 and the second body 2 are not folded, the first buckle position 11 and the second buckle position 21 can be respectively clamped with both ends of an external support device 9 (as shown in Figure 7 ) to fix the portable thermal imager to the external support device 9.

[0042] It can be understood that when the first body 1 and the second body 2 are not folded, that is, when the portable thermal imager is unfolded, it has two states. One is that the first body 1 and the second body 2 are close to and abut against each other (as shown in Figure 2 ), and the other is that the first body 1 and the second body 2 are far away from each other (as shown in Figure 1 ). In these two states, by respectively engaging the first buckle 11 and the second buckle 21 with both ends of the external support device 9, the portable thermal imager can be fixed to the external support device 9, making the portable thermal imager serve as the thermal imaging system of the external support device 9, facilitating the use of the external support device 9 as a detection tool to monitor the temperature of the target object at any time. It should be noted that the first body 1 and the second body 2 being far away from each other is relative to the first body 1 and the second body 2 being close to and abutting against each other. Here, no specific limitation is imposed on the specific distance between the first body 1 and the second body 2 when they are far away from each other. The first body 1 and the second body 2 can have a maximum distance when they are far away from each other, and the distance between the first body 1 and the second body 2 when they are far away from each other can be any value within the maximum distance. That is, the portable thermal imager is telescopic and the telescopic distance is adjustable, so that the portable thermal imager can be adapted to external support devices 9 of different sizes, thereby expanding the application scenarios of the portable thermal imager.

[0043] When the first body 1 and the second body 2 are close to and abut against each other, the first body 1 and / or the second body 2 can also be flipped to make the portable thermal imager in a folded state (as shown in Figure 3 ). After folding, the first body 1 and the second body 2 at least partially overlap. Therefore, the size of the portable thermal imager is reduced, making the structure of the portable thermal imager small and convenient to carry. At this time, the portable thermal imager can also be used as an independent thermal imaging device to facilitate temperature detection in many narrow spaces, making its application scenarios wider.

[0044] It can be seen that the portable thermal imager provided by the embodiment of the present invention has the functions of being foldable and telescopic, can be adapted to more models and sizes of external support devices 9 within a limited size space, and can extend into more narrow spaces for temperature detection. It has a wide range of application scenarios, and has a small and compact structure, small size, and is convenient to carry.

[0045] It should be noted that the embodiment of the present invention does not make specific limitations on the external support device 9. For example, the external support device 9 can be a mobile phone or a tablet, etc. Of course, it can also be other external support devices 9 suitable for hanging the portable thermal imager.

[0046] In addition, please continue to refer to Figure 1 and Figure 3, considering the simplicity of the connection structure between the first body 1 and the second body 2, in some embodiments, an elastic member 3 is connected between the first body 1 and the second body 2, and the elastic member 3 can be telescoped along the first direction. That is to say, in this embodiment, the movable connection between the first body 1 and the second body 2 is realized through the elastic member 3. By applying an external force to cause elastic deformation of the elastic member 3, the first body 1 and the second body 2 can be moved away from each other, and the distance between the first body 1 and the second body 2 moving away from each other can be adjusted by the amount of deformation of the elastic member 3. When the external force is removed, the elastic member 3 restores its elastic deformation, and the first body 1 and the second body 2 can be moved closer to each other. In addition, since the elastic member 3 has a bending characteristic and can be bent under the action of an external force, the first body 1 and the second body 2 can be turned and folded. That is, when the first body 1 and the second body 2 are folded, the elastic member 3 is in a bent state. It can be seen that in this embodiment, the elastic member 3 is ingeniously used to realize the telescopic and turnable folding functions of the portable thermal imager, and the structure is simple and convenient to implement.

[0047] It should be noted that the specific structure of the elastic member 3 in this embodiment is not limited. For example, the elastic member 3 can be a spring or an elastic block, etc.

[0048] In addition, the specific number of the elastic members 3 in this embodiment is not limited. The number of the elastic members 3 can be one, or at least two. In some embodiments, the number of the elastic members 3 is two, and the two elastic members 3 are arranged at intervals. That is, the first body 1 and the second body 2 are connected by two elastic members 3.

[0049] In addition, in some embodiments, after the first body 1 and the second body 2 are turned and folded, the first buckle 11 also has the function of clamping the second body 2, and / or the second buckle 21 also has the function of clamping the first body 1. That is to say, after the first body 1 and the second body 2 are turned and folded, the first body 1 and the second body 2 are clamped by using the first buckle 11 and the second body 2, and / or the first body 1 is clamped by using the second buckle 21, so as to realize the relative fixation of the positions of the first body 1 and the second body 2, so that the first body 1 and the second body 2 maintain the folded state. This solution is particularly applicable when the first body 1 and the second body 2 are connected by the elastic member 3. By clamping the first body 1 and the second body 2 by using the first buckle 11 and the second body 2, and / or by clamping the first body 1 by using the second buckle 21, the elastic restoring force of the elastic member 3 can be overcome, and the phenomenon that the first body 1 and the second body 2 are easily opened due to the elastic member 3 being bent by the elastic member 3 can be avoided.

[0050] Further, please refer to Figure 4In some embodiments, the first body 1 is provided with a first cavity 12, the second body 2 is provided with a second cavity 22, and the elastic member 3 is completely contained in the first cavity 12 and the second cavity 22 when it is not stretched. That is to say, the present embodiment utilizes the first cavity 12 and the second cavity 22 to contain the elastic member 3 when it is not stretched, so that the elastic member 3 is a hidden design to prevent the elastic member 3 from being exposed to the outside. On the one hand, it has a protective effect on the elastic member 3 and can increase the service life of the elastic member 3. On the other hand, it makes the appearance of the portable thermal imager simple and beautiful. Moreover, when the elastic member 3 is not stretched, it is completely contained in the first cavity 12 and the second cavity 22, which can further reduce the overall size of the portable thermal imager. When the elastic member 3 is a spring, the structure is simple and occupies a small space, so that the internal space of the first body 1 and the second body 2 is more sufficient.

[0051] It should be noted that the present embodiment does not limit the lengths of the elastic member 3 located in the first cavity 12 and the second cavity 22 respectively. In some embodiments, half of the elastic member 3 is located in the first cavity 12, and the other half of the elastic member 3 is located in the second cavity 22, that is, the elastic member 3 is symmetrically arranged with respect to the abutting surfaces of the first body 1 and the second body 2.

[0052] For further information, please refer to Figure 6 In some embodiments, arc-shaped corner stoppers 4 are respectively provided in the first cavity 12 and the second cavity 22. The arc-shaped corner stoppers 4 correspond to the corner positions of the elastic member 3 after the first body 1 and the second body 2 are flipped over. The arc-shaped corner stoppers 4 are used to limit the corner positions of the elastic member 3. That is to say, when the first body 1 and the second body 2 are flipped over, the elastic member 3 is in a bent state, and the elastic member 3 has a corner position to achieve the bending of the elastic member 3. At this time, the arc-shaped corner stoppers 4 are used to limit the corner position of the elastic member 3, which is conducive to ensuring that the elastic member 3 has a suitable position, avoiding the position of the bent part of the elastic member 3 to be uncertain after the bending, scratching other components in the first body 1 and the second body 2, or causing the elastic member 3 to jam when it is unfolded, etc., which is conducive to improving the reliability of the elastic member 3.

[0053] Also, please refer to Figure 4 , Figure 5 and Figure 6, in order to facilitate the fixation of the elastic member 3, in some embodiments, fixing members 5 are respectively provided in the first cavity 12 and the second cavity 22, and both ends of the elastic member 3 are respectively connected to the fixing members 5 in the first cavity 12 and the second cavity 22. That is to say, in this embodiment, the fixing members 5 are used to fix the ends of the elastic member 3 to realize the fixation of both ends of the elastic member 3. The specific structure of the fixing member 5 and the specific connection manner between the elastic member 3 and the fixing member 5 are not limited in this embodiment. For example, in some embodiments, the fixing member 5 is a columnar member, the elastic member 3 is a spring, and both ends of the spring are respectively hung on the corresponding columnar members. Further, a limiting structure may be provided on the columnar member to limit the end of the spring to prevent the end of the spring from detaching from the columnar member.

[0054] In addition, please refer to Figure 3 , in order to improve the stability of the first body 1 and the second body 2 in the state of being close to and abutting against each other, in some embodiments, the first body 1 is provided with a first limiting portion 13, and the second body 2 is provided with a second limiting portion 23. When the first body 1 and the second body 2 are flipped and unfolded, the first limiting portion 13 and the second limiting portion 23 cooperate to limit the position, so that the first body 1 and the second body 2 are relatively fixed when they are close to and abut against each other. That is to say, when the first body 1 and the second body 2 are flipped and unfolded and not yet stretched, the first body 1 and the second body 2 are close to and abut against each other. At this time, the first limiting portion 13 and the second limiting portion 23 cooperate to limit the position, so as to limit the relative position of the first body 1 and the second body 2, ensure that the two remain in the state of being close to and abutting against each other, and improve the stability of the portable thermal imager in this state.

[0055] It should be noted that the specific structures of the first limiting portion 13 and the second limiting portion 23 are not limited in this embodiment, as long as the first limiting portion 13 and the second limiting portion 23 can cooperate to limit the position. For example, in some embodiments, the first limiting portion 13 is a first annular columnar structure, the second limiting portion 23 is a second annular columnar structure, and the inner hole of the first annular columnar structure cooperates with the outer peripheral surface of the second annular columnar structure to limit the position. Of course, in some other embodiments, it may also be such a solution that one of the first limiting portion 13 and the second limiting portion 23 is a limiting column, and the other is a limiting hole. Before the first body 1 and the second body 2 are flipped and unfolded and not yet stretched, the limiting column is inserted into the limiting hole to realize the relative fixation of the first body 1 and the second body 2.

[0056] In addition, please combine Figure 2 and Figure 3, in some embodiments, the first snap 11 and the second snap 21 are arranged in a staggered manner so that the first snap 11 and the second snap 21 do not overlap after the first body 1 and the second body 2 are turned over and overlapped. That is to say, when the first body 1 and the second body 2 are folded, the first snap 11 and the second snap 21 do not have an overlapping part, which is beneficial to reducing the size of the portable thermal imager after folding. At the same time, it is beneficial to make the designs of the first snap 11 and the second snap 21 not interfere with each other and reduce the design difficulty.

[0057] It should be noted that in this embodiment, the specific structures and distributions of the first snap 11 and the second snap 21 are not limited, as long as the first snap 11 and the second snap 21 do not overlap after the first body 1 and the second body 2 are turned over and overlapped. In some embodiments, the number of the first snaps 11 is one, and it is arranged at the center of the end of the first body 1 away from the second body 2. The number of the second snaps 21 is two, which are respectively arranged on both sides of the center of the end of the second body 2 away from the first body 1, so that after the first body 1 and the second body 2 are turned over and folded, the first snap 11 is located between the two second snaps 21. This structure has good symmetry. When the first body 1 and the second body 2 are folded and the first body 1 and the second body 2 are relatively fixed by the engagement of the first snap 11 with the second body 2 and the engagement of the second snap 21 with the first body 1, it is beneficial to make the overall force on the first body 1 and the second body 2 more balanced, so that the two are fixed more reliably, and it is more beneficial to ensure that the portable thermal imager is in a folded state.

[0058] In addition, please refer to Figure 4 and Figure 5, in some embodiments, one of the first body 1 and the second body 2 is provided with a battery 6, and the other is provided with electronic components. The electronic components are connected to the battery 6 through a connecting wire 7. The elastic member 3 is provided with a through hole, and the connecting wire 7 is passed through the through hole. That is to say, in this embodiment, the battery 6 and the electronic components are respectively arranged in the first body 1 and the second body 2, which is beneficial to reasonably utilize the internal space of the first body 1 and the second body 2, making the structures of the first body 1 and the second body 2 more miniaturized. The connecting wire 7 is flexible and bendable. At the same time, the connecting wire 7 can have a certain stretching margin to adapt to the stretching of the portable thermal imager. When the portable thermal imager is retracted, the connecting wire 7 can be bent arbitrarily and stored inside the first body 1 and the second body 2. Therefore, this connection method of the battery 6 and the electronic components does not affect the telescopic and foldable performance of the portable thermal imager. In addition, it can be understood that the connecting wire 7 passes through the through hole of the elastic member 3. For example, when the elastic member 3 is a spring, the connecting wire 7 is passed through the inner hole of the spring, which is beneficial to save space. And when the portable thermal imager is folded or telescoped, the deformation trends of the elastic member 3 and the connecting wire 7 are the same. Arranging the connecting wire 7 in the through hole of the elastic member 3 can also use the through hole to limit the connecting wire 7, making the connecting wire 7 more regular and avoiding the connecting wire 7 being disorderly inside the first body 1 and the second body 2.

[0059] In addition, please refer to Figure 3 , in some embodiments, at least one of the first body 1 and the second body 2 is provided with an infrared lens 8. That is to say, in this embodiment, arranging the infrared lens 8 in at least one of the first body 1 and the second body 2 is beneficial to collecting the temperature of the target object.

[0060] Please refer to Figure 7 , in addition to the above-mentioned portable thermal imager, the present invention also provides a thermal imager system including the portable thermal imager disclosed in the above embodiments. The thermal imager system further includes an external support device 9, and the portable thermal imager is fixed to the external support device 9 through the first buckle position 11 of the first body 1 and the second buckle position 21 of the second body 2.

[0061] Since the thermal imager system includes the above-mentioned portable thermal imager, it has the same beneficial effects as the portable thermal imager and will not be elaborated here.

[0062] It should also be noted that in this specification, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations.

[0063] The various embodiments in this specification are described in a progressive manner. Each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.

[0064] The above has introduced in detail the portable thermal imager and the thermal imager system provided by the present utility model. Specific examples are used in this article to expound the principle and implementation manner of the present utility model. The description of the above embodiments is only used to help understand the method and its core idea of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present utility model, several improvements and modifications can be made to the present utility model, and these improvements and modifications also fall within the protection scope of the present utility model.
