The Internet of Things terminal 10 is configured to include a terminal capable of operating in the Internet of Things. For example, the IoT terminal 10 is a terminal used in industrial sites and may include a variety of industrial IoT terminals 10, such as terminals used in smart factories or terminals that measure temperature, humidity, etc. Here, the IoT terminal 10 includes a case 110, a button 120, a lever 130, a spring 140, a PBA 150, an antenna 160, a battery 170, and a fastener 180. It can be included.

The case 110 is configured to surround and protect the internal parts or components of the Internet of Things terminal 10, and may include an upper case 111 and a lower case 112. That is, the upper case 111 and the lower case 112 are combined to form a roughly rectangular shape, and the interior of the Internet of Things terminal 10 is located in the internal space of the rectangular parallelepiped formed by the upper case 111 and the lower case 112. Configurations may be provided. The upper case 111 is formed with an upper seating groove 1110 for fitting with the upper seating protrusion 211 formed on the side wall 210 of the bracket 20, and the lower case 112 is formed on the side wall of the bracket 20. A lower seating groove 1120 is formed to fit into the lower seating protrusion 212 formed at 210. The upper seating groove 1110 and the lower seating groove 1120 may be formed to have a substantially polygonal or circular cross-section and a predetermined length. At this time, the polygon may include, for example, a triangle, square, pentagon, hexagon, or octagon.

The button 120 is pressed by the user to operate the IoT terminal 10. This button 120 may be provided on the surface of the upper case 111. At this time, the button 120 may be provided in the opposite direction of the lever 130.

When the Internet of Things terminal 10 and the bracket 20 are combined, the lever 130 can lock the Internet of Things terminal 10 and the bracket 20, or lock the bracket 20. . This lever 130 is located at an end opposite to the button 120, and may protrude outward from the inside of the IoT terminal 10 toward the bottom of the lower case 112. Accordingly, when the lever 130 protrudes outward toward the bottom of the lower case 112, the Internet of Things terminal 10 and the bracket 20 are locked. Conversely, when the lever 130 is pushed in toward the inside of the lower case 112, the Internet of Things terminal 10 and the bracket 20 are in an unlocked state. The lever 130 consists of an upper lever 131, a lower lever 132, and a lever handle 133. That is, the lever 130 is a pillar with a cylindrical shape or a polygonal cross-section and is provided with an upper lever 131 and a lower lever 132, and the lower lever 132 has a larger cross-sectional area than the upper lever 131, or The cross-sectional areas of the lower lever 132 and the upper lever 131 may be formed to be the same size, or the lower lever 132 may be formed to have a smaller cross-sectional area than the upper lever 131. In addition, the lever handle 133 has a cross-section of approximately Ω shape and is coupled between the upper lever 131 and the lower lever 132. Accordingly, the lower lever 132 and the upper lever 131 can move upward due to the external force applied to the lever handle 133, and thus the lower lever 132 moves downward toward the bottom of the lower case 112. It may be introduced into the interior of the case 112. At this time, the polygon may include, for example, a triangle, square, pentagon, hexagon, or octagon.

The spring 140 is combined with the lever 130 to fix the lever 130. This spring 140 uses elastic restoring force when the lever 130 locks the IoT terminal 10 and the bracket 20 to move the position of the lever 130 toward the bottom of the lower case 112. It can be made to protrude. That is, the lower lever 132 is retracted into the case when the lever handle 133 is lifted by an external force, and the retracted state of the lower lever 132 can be fixed. At this time, the spring 140 is compressed by the upper lever 131 because the external force applied to the lever handle 133 is also transmitted to the upper lever 131. Afterwards, when the external force disappears, the upper lever 131 and the lower lever 132 move toward the bottom of the lower case 112 due to the elastic restoring force of the spring 140, and accordingly, the lower lever 132 moves toward the bottom of the lower case 112. It may protrude toward the bottom of the case 112.

The bracket 20 is configured to protect the IoT terminal 10 and the asset 30 by combining with the IoT terminal 10 and the asset 30. This bracket 20 may be made of a material such as plastic or non-ferrous metal so as not to affect communication of the Internet of Things terminal 10. In addition, the shape of the bracket 20 is a rectangular parallelepiped and the top and one side are open. That is, the bracket 20 has three side surfaces based on a rectangular parallelepiped, and the remaining one side is open as an opening 240. Additionally, the bottom surface is formed and the top surface is open. Specifically, a seating portion 200, a side wall 210, a locking hole 220, and an asset coupling portion 230 are formed.

The seating portion 200 is a portion that accommodates the Internet of Things terminal 10. That is, the seating portion 200 refers to the inner bottom surface of the bracket 20. Therefore, the IoT terminal 10 can be seated on the seating portion 200 and coupled to the bracket 20. It may be provided in an approximately square shape.

The side wall 210 is configured to support the side of the IoT terminal 10 when the IoT terminal 10 is seated on the seating unit 200, and is formed at a right angle at a predetermined height from the three edges of the seating unit 200. It is formed by This side wall 210 has at least one seating protrusion formed on the inner wall to support the upper case 111 and at least one lower case 112. That is, a plurality of upper seating protrusions 211 and a plurality of lower seating protrusions 212 are formed on the side wall 210, respectively, to secure the upper seating groove 1110 of the upper case 111 and the lower seating portion of the lower case 112. It can be coupled by engaging and fitting into the groove 1120. At this time, the upper seating protrusion 211 is formed at a higher position than the lower seating protrusion 212. The plurality of upper seating protrusions 211 and the plurality of lower seating protrusions 212 are formed to have a predetermined length along the longitudinal direction of the inner wall of the side wall, and may have a polygonal or circular cross-section. At this time, the polygon may include, for example, a triangle, square, pentagon, hexagon, or octagon.

The locking hole 220 is configured so that the lower lever 132 protrudes and the seating portion 200 penetrates. This locking hole 220 is formed to a predetermined size on one side of the seating portion 200 in the direction of the opening 240 of the seating portion 200. The locking hole 220 may be formed to be larger than the lower lever 132 so that the lower lever 132 can protrude. Here, the lock hole 220 may be formed in a polygonal or circular shape similar to the shape of the lower lever 132. At this time, the polygon may include, for example, a triangle, square, pentagon, hexagon, or octagon.

The asset combination unit 230 is a configuration where the asset 30 is combined. This asset coupling portion 230 is formed on the opposite side of the seating portion 200, and thus the asset 30 can be positioned between the Internet of Things terminal 10 and the bracket 20. That is, the IoT terminal 10 is coupled to the inside of the bracket 20, and the asset 30 is coupled to the outside of the bracket 20.

The asset 30 is attached to the Internet of Things terminal 10 and is configured to manage the Internet of Things terminal 10.

Hereinafter, the process of combining the Internet of Things terminal 10 and the bracket 20 will be described with reference to the drawings.

Figure 5 is a diagram showing the process of coupling the Internet of Things terminal 10 and the bracket 20 coupled thereto to the Internet of Things terminal 10 and the bracket 20 according to an embodiment of the present invention.

As shown in FIG. 5, the IoT terminal 10 can be coupled by being pushed into the bracket 20 by an external force. That is, the IoT terminal 10 can be coupled to the bracket 20 by sliding toward the opening 240 of the bracket 20 at a position in line with the bracket 20 and being seated on the seating portion 200. .

Here, an upper seating groove 1110 is formed in the upper case 111 of the IoT terminal 10, and a lower seating groove 1120 is formed in the lower case 112.

In addition, the bracket 20 has at least one upper seating protrusion 211 and at least one lower seating protrusion 212 formed at a right angle to the inner wall of the side wall 210, that is, at a predetermined height from the inner wall. It is done. These upper seating protrusions 211 and lower seating protrusions 212 are formed at a relatively high position on the side wall 210, and the lower seating protrusions 212 are lower than the upper seating protrusions 211. formed by location.

In addition, when a plurality of upper seating protrusions 211 are formed along the longitudinal direction of the inner wall of the side wall 210, each upper seating protrusion 211 may be formed in a straight line and spaced a predetermined distance apart from each other. This can be equally applied to the lower seating protrusion 212. Accordingly, at least one lower seating protrusion 212 may be formed at a height below the space where the two upper seating protrusions 211 are spaced apart from each other. That is, the lower seating protrusion 212 is formed at a distance from the upper seating protrusion 211 on the inner wall of the side wall, and is formed at a lower position than the upper seating protrusion 212.

Therefore, when the IoT terminal 10 is slidably inserted into the bracket 20, the upper seating protrusion 211 engages with the upper seating groove 1110 by external force, and the lower seating protrusion 212 engages with the lower seating groove ( By engaging and fitting with 1120, the IoT terminal 10 can be guided, aligned, and seated on the bracket 20. In addition, it can help to secure the IoT terminal 10 to the bracket 20.

At this time, the upper seating protrusion 211, upper seating groove 1110, lower seating protrusion 212, and lower seating groove 1120 are formed in a triangle, square, pentagon, hexagon, or octagon, so they can be firmly coupled to each other. You can.

Conversely, when the Internet of Things terminal 10 and the bracket 20 are disconnected, an external force is applied in the direction opposite to the direction in which the Internet of Things terminal 10 was inserted, and the Internet of Things terminal 10 is applied to the bracket 20. It leaves in the opposite direction in a sliding manner, and at this time, the upper seating protrusion 211 and the lower seating protrusion 212 separate from the upper seating groove 1110 and the lower seating groove 1120 in a sliding manner opposite to when they are retracted. I do it. Accordingly, the IoT terminal 10 can be disconnected from the bracket 20.

Hereinafter, fixing the IoT terminal 10 and the bracket 20 after they are combined will be described with reference to the drawings.

Figure 6 shows the locked state and the unlocked state of the Internet of Things terminal 10 and the bracket 20 after the Internet of Things terminal 10 and the bracket 20 coupled thereto according to an embodiment of the present invention are coupled. This is a drawing showing this.

As shown in FIG. 6, a lever 130 is provided on one side of the Internet of Things terminal 10 through which the user can adjust the coupling state of the Internet of Things terminal 10 and the bracket 20. That is, the lever 130 is coupled to the spring 140 and basically protrudes from the bottom surface of the lower case 112 in the IoT terminal 10 by the spring 140.

At this time, when the user applies an external force to raise the lever 130 upward, the spring 140 rises and is compressed, and the lever 130 also rises. Accordingly, the lever 130 passes through the bottom surface of the lower case 112 and is introduced into the interior.

Afterwards, when the external force that raises the lever 130 upward disappears, the lever 130 may protrude from the bottom surface of the lower case 112 due to the elastic restoring force of the spring 140 coupled to the lever 130.

Therefore, when the Internet of Things terminal 10 is seated on the bracket 20 with the lever 130 lifted by an external force and the external force disappears, it is attached to the bottom surface of the bracket 20 by the elastic restoring force of the spring 140. The lever 130 passes through the formed locking hole 220. Accordingly, the IoT terminal 10 and the bracket 20 may be locked by the lever 130.

Afterwards, when the lever 130 is lifted upward by an external force, the lever 130 is retracted into the bottom surface of the lower case 112 and the Internet of Things terminal 10 and the bracket 20 are unlocked. Accordingly, the IoT terminal 10 may be separated from the bracket 20.

Meanwhile, in the present invention, the combined state of the Internet of Things terminal 10 and the bracket 20 can be detected through a sensor.

Specifically, the IoT terminal 10 may be equipped with an illumination sensor, and the lower case 112 may be equipped with a transparent window on the bottom. Accordingly, when the Internet of Things terminal 10 is seated on the bracket 20, the illuminance sensor can detect the darkening as the bottom of the lower case 112 becomes dark, which is detected by the control unit of the Internet of Things terminal 10 ( It can be detected that it is coupled to the bracket 20 (not shown).

If brightening is detected after darkening is detected, the IoT terminal 10 and the bracket 20 may be sensed as being disconnected.

Additionally, the IoT terminal 10 may be equipped with an earth magnetic field sensor, and the lower case 112 may be equipped with a magnet on the bottom. Accordingly, when the Internet of Things terminal 10 is seated on the bracket 20, the geomagnetic field sensor can detect a magnet as the magnetic field is detected from the bottom of the lower case 112, which is the magnet of the Internet of Things terminal 10. The control unit (not shown) can detect that it is coupled to the bracket 20.

If, after the magnetic field is detected, it is detected that the detected magnetic field disappears again, it may be detected that the IoT terminal 10 and the bracket 20 are disconnected.

The preferred embodiments of the present invention described above have been disclosed for illustrative purposes, and those skilled in the art will be able to make various modifications, changes, and additions within the spirit and scope of the present invention, and such modifications and changes will be possible. and additions should be regarded as falling within the scope of the patent claims of the present invention.
