Description

Technical Field

[0001] This application relates to the technical field of electronic devices, and particularly to an interface connection structure, a hot-pluggable device, and a thermal imager. Background Art

[0002] Infrared rays are a type of electromagnetic wave, having the same essence as radio waves and visible light. Any object in nature with a temperature higher than absolute zero (0 °C or -273 °C) emits infrared rays of various wavelengths. The higher the temperature of the object, the greater the intensity of the emitted infrared rays. An infrared thermal imager precisely utilizes this principle to detect the infrared radiation of a target object and, through means such as photoelectric conversion and electrical signal processing, converts the temperature distribution map of the target object into a video image for presentation.

[0003] One of the greatest features of a pocket-sized infrared thermal imager is its portability, which can be easily put into a pocket or backpack and used anytime, anywhere. Whether it is for building inspections, electrical fault troubleshooting, or outdoor adventures, it can provide strong support for users. The inventors found the following problems in the prior art during the implementation of this application: Currently, when a pocket infrared thermal imager is connected to an electronic device such as a mobile phone through an interface module, the plug head of the interface module is designed with a fixed direction. The axial direction of the thermal imager lens can only be the same as or opposite to the direction of the mobile phone screen. When observing things, the mobile phone must be rotated along with the direction of the thermal imager lens so that the user can observe the content captured by the thermal imager lens, which is not very convenient to use. In addition, the plug head of the interface module is fixed and protrudes from the outer shell of the thermal imager product. During carrying, the plug head is always in an exposed state, which is not very convenient to carry. At the same time, since the plug head is always in a fixed exposed state, once the device drops, it is very likely to damage the exposed plug head, reducing the reliability of the product. Summary of the Invention

[0004] Based on this, this application provides an interface connection structure, a hot-pluggable device, and a thermal imager to improve the problem of inconvenient use caused by the fixed plug head of the interface module in the prior art.

[0033] Please refer to Figure 1 and Figure 2, embodiments of the present application provide a hot-pluggable device, which includes an interface connection structure. The hot-pluggable device can be, for example, a thermal imager 10, etc. As long as the hot-pluggable device has a need to adjust the relative position when connecting to other electronic devices through the interface module 12, the interface connection structure of this embodiment can be adopted, and the specific scope of use is not limited. The following takes the thermal imager 10 as an example for explanation.

[0034] As Figure 3 and Figure 4 shown, the interface connection structure of this embodiment includes a housing 11, an interface module 12, and a circuit board 15. The interface module 12 includes a plug head 121 and a base 122 which are connected; the interface module 12 is arranged outside the housing 11, and the circuit board 15 is arranged inside the housing 11. The housing 11 is the outer shell of the thermal imager 10. The thermal imager 10 further includes an infrared lens 13 and an infrared detector 14. The infrared detector 14 is arranged inside the housing 11, and the receiving end is located on the optical path of the infrared lens 13. The infrared detector 14 is electrically connected to the circuit board 15. The interface module 12 is used to connect the thermal imager 10 to other electronic devices, such as electronic devices with display functions like mobile phones 20, tablets, or computers, etc. The interface type of the plug head 121 includes various types such as Lightning, Type-C, or USB-A, etc., and the specific interface form is not limited.

[0035] A sliding groove 111 is provided on the housing 11. The base 122 is installed in the sliding groove 111, and the base 122 is used to rotate along the guiding direction of the sliding groove 111 to change the relative position between the plug head 121 and the housing 11; a contact point 123 is provided on the base 122. The contact point 123 is electrically connected to the plug head 121, and when the base 122 rotates to the required position, the contact point 123 is used to conduct or disconnect from the circuit board 15.

[0036] The interface module 12 is arranged on one side surface of the housing 11. The infrared lens 13 can be arranged on any surface of the housing 11 adjacent to the side surface where the interface module 12 is arranged, as long as the aiming direction of the infrared lens 13 can be changed when the base 122 rotates relative to the housing 11, and the specific setting position can be determined according to actual needs.

[0037] The base 122 can be, for example, disc-shaped, and the sliding groove 111 is a circular groove corresponding to the base 122. The base 122 is clamped in the sliding groove 111. When the base 122 rotates relative to the housing 11, the position between the plug head 121 and the housing 11 can be changed. In actual use, the base 122 does not move, but the housing 11 rotates, and the infrared lens 13 on the housing 11 changes the aiming direction as the housing 11 rotates. At this time, the base 122 can only rotate in one direction, and the direction of the plug head 121 always remains perpendicular to the surface of the housing 11 (the surface on the side where the interface module 12 is installed). At this time, the interface module 12 protrudes from the housing 11, which is not convenient for carrying, and there is a risk of damage when the thermal imager 10 falls. Therefore, the plug head 121 and the base 122 can also be designed in a foldable form. The plug head 121 and the base 122 are hinged by components such as a rotating shaft. When in use, the plug head 121 can be flipped outwards to extend out of the surface of the housing 11 to connect with other electronic devices. When not in use, the plug head 121 can be flipped inwards to be nearly parallel to the surface of the housing 11 (the surface on the side where the interface module 12 is installed) and stored in the plug slot 112 beside the sliding groove 111, so that the plug head 121 is located in the recess on the surface of the housing 11.

[0038] In one embodiment, the base 122 is a spherical base 122, and the sliding groove 111 is a spherical sliding groove 111 corresponding to the spherical base 122. The spherical base 122 is used to roll in the spherical sliding groove 111. The contact point 123 protrudes relative to the base 122, and the plug head 121 and the contact point 123 are symmetrically arranged on both sides of the center of the base 122, that is, the plug head 121 and the contact point 123 are respectively located at two opposite ends of the spherical base 122.

[0039] As Figure 4 shown, a circle of limit blocks 113 is provided at the top edge of the sliding groove 111. The limit blocks 113 are used to block the contact point 123 and at the same time to prevent the base 122 from separating from the sliding groove 111. That is, except for the limit blocks 113, the radius of the spherical sliding groove 111 at other positions is the same as the rotation radius formed at the contact point 123, and the contact point 123 can roll freely in the sliding groove 111 along with the spherical base 122. A plug slot 112 is also provided on the housing 11 beside the sliding groove 111. The plug slot 112 is communicated with the sliding groove 111. The plug slot 112 is used to accommodate the plug head 121. When the plug head 121 rotates towards the housing 11, the plug head 121 can be accommodated in the plug slot 112 to prevent the plug head 121 from protruding from the surface of the housing 11. At this time, the socket module is in an unoperated state.

[0040] A pressing switch 16 is also provided between the bottom of the sliding groove 111 and the circuit board 15. The pressing switch 16 is used to conduct or disconnect the connection relationship between the interface module 12 and the circuit board 15.

[0041] As shown in Figure 4 and Figure 5 the figure, an elastic member (not shown) is provided at the bottom of the push switch 16. The elastic member can be, for example, a spring, which is always in a compressed state. The elastic member is used to reset the push switch 16 in a direction away from the circuit board 15 when the external force acting on the push switch 16 is lost. When the pressing portion of the push switch 16 is stressed, it will move in a direction away from the sliding groove 111. When the external force is lost, the elastic member can push the pressing portion of the push switch 16 in a direction close to the sliding groove 111, so that when pressed again, the push switch 16 and the contact point 123 can maintain good contact. To enhance the reliability of the push switch 16, a switch guiding column 17 can also be provided at the pressing portion of the push switch 16. The guiding column can be fixedly connected or separated from the push switch 16, and specific requirements are not made. The switch guiding column 17 includes a first body portion 171 and a second body portion 172 which are connected. The first body portion 171 is provided at one end close to the interface module 12. The surface area of the first body portion 171 at one end close to the interface module 12 is larger than the surface area of the second body portion 172 at one end away from the interface module 12. The first body portion 171 is used to abut against the contact point 123, and the second body portion 172 is used to abut against the push switch 16. For example, the switch guiding column 17 can be a stepped cylindrical structure. Both the first body portion 171 and the second body portion 172 are in a cylindrical shape. The diameter of the first body portion 171 is larger than the diameter of the second body portion 172. The first body portion 171 has a relatively large end surface area, making it easier for the contact point 123 to abut against the switch guiding column 17, while the second body portion 172 has a relatively small end surface area, which can more accurately contact the pressing portion of the push switch 16 and is easy to apply force to the pressing portion, making the connection of the push switch 16 more stable and reliable.

[0042] When the base 122 is in a disc shape, other components of the interface connection structure can be completely or incompletely the same as when the base 122 is in a spherical shape, as long as the corresponding functions can be achieved. For example, when the base 122 is in a disc shape, contact points 123, switch guiding columns 17, push switches 16 and other structures can also be provided at the bottom of the base 122, or the base 122 can be directly connected to the circuit board 15 through the contact points 123 or other connection points, which does not affect the realization of the functions of the interface connection structure.

[0043] In this embodiment, the interface module 12 is provided at the top (in the illustrated direction) of the housing 11, and the infrared lens 13 is provided on the side wall adjacent to the top housing 11.

[0044] As shown in Figure 1As shown, when the thermal imager 10 is connected to and used with an electronic device such as a mobile phone 20, the plug head 121 can be rotated outwards, and the plug head 121 is perpendicular to the top surface of the housing 11. At this time, the contact point 123 rolls to the bottom of the chute 111 and abuts against the switch guide post 17, thereby applying a force to the push switch 16 to form an electrical connection between the circuit board 15 and the interface module 12. After inserting the plug head 121 into the socket of the electronic device, the thermal imager 10 can be connected to the electronic device, such as Figure 6 and Figure 7 As shown, when it is necessary to view and observe different orientations, the housing 11 can be rotated while keeping the electronic device stationary, so that the housing 11 drives the infrared lens 13 to change the relative position relationship with the electronic device, thereby changing the aiming direction of the infrared lens 13, and then different orientations of the object conditions can be observed while keeping the electronic device stationary, which is very convenient. Such as Figure 2 As shown, when the operation of the thermal imager 10 is completed, the plug head 121 can be pulled out from the electronic device, and the plug head 121 is rotated inwards. The contact point 123 rolls towards the direction of the limit stop 113 and separates from the switch guide post 17. At this time, the push switch 16 loses the external force, so that the interface module 12 and the circuit board 15 are disconnected. The plug head 121 is rotated into the plug slot 112 for storage, making the thermal imager 10 more convenient to carry. At the same time, it can avoid damage to the interface module 12 caused by accidental dropping and other situations, and enhance the reliability of use of the thermal imager 10.

[0045] The interface connection structure, hot-pluggable device and thermal imager of the embodiments of the present application have a simple structure and are convenient to use, effectively solving the problem of inconvenient observation during use, and improving the safety and reliability of the device.

[0047] The above is only the specific implementation manner of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present application can easily think of changes or substitutions, which should be covered by the protection scope of the present application.
