Detailed Description
In the following description, numerous implementation details are set forth in order to provide a thorough understanding of the present invention. It should be understood, however, that these implementation details are not to be interpreted as limiting the invention. That is, in some embodiments of the invention, such implementation details are not necessary. In addition, for the sake of simplicity, some conventional structures and elements are shown in the drawings in a simple schematic manner. And features of different embodiments may be applied interactively, if possible.
Fig. 1 is a schematic perspective view illustrating an application of a calibration apparatus 100 according to an embodiment of the invention. When the human body scanner 200 is to be calibrated, the calibration apparatus 100 is installed into the human body scanner 200 as shown in fig. 1. For example, the body scanner 200 may have a plurality of sensors 210, and when the body scanner 200 is in operation, the sensors 210 are oriented to measure the body size of a user (not shown) standing in the body scanner 200.
Referring to fig. 2, a rear view of the calibration apparatus 100 of fig. 1 is shown. In the present embodiment, as shown in fig. 1 to fig. 2, the calibration apparatus 100 includes a housing 110, a reel 120 (see fig. 4 for the reel 120), a bracket 130, a film structure 140, a plurality of light emitting diodes 150, and a power source 160. The housing 110 is disposed on the ground inside the body scanner 200, and the reel 120 is pivoted inside the housing 110. The bracket 130 is connected to the housing 110, and the bracket 130 is retractable in a first direction D1, the first direction D1 being substantially perpendicular to the axial direction a of the spool 120. The membrane structure 140 is connected to the spool 120 at one end and to the support 130 at the other end. In the present embodiment, as shown in fig. 1 to 2, the membrane structure 140 may further have a connecting rod 148, and the connecting rod 148 is located at an end of the membrane structure 140 away from the winding shaft 120 and configured to detachably connect the bracket 130. The membrane body structure 140 also has a first surface 141 and a second surface 142 opposite to each other. The light emitting diodes 150 are distributed on the first surface 141 and the second surface 142, and the power source 160 is electrically connected to the light emitting diodes 150. In practical applications, the film structure 140 may be made of cloth, paper, or plastic, but the invention is not limited thereto.
In calibrating the body scanner 200, the user activates the body scanner 200 and the calibration apparatus 100 located within the body scanner 200. After the calibration apparatus 100 is started, the light emitting diodes 150 distributed on the first surface 141 and the second surface 142 of the film body structure 140 emit bright light, and after the human body scanner 200 is started, the sensor 210 of the human body scanner 200 measures the bright position of the light emitting diodes 150, and the sensor 210 is adjusted and calibrated by a processing device (the processing device is not shown in fig. 1-2), which is convenient and simple in process.
To make the calibration process more accurate, the first surface 141 of the film body structure 140 has at least one pattern P, as shown in fig. 1. In this way, the sensor 210 of the body scanner 200 can also measure the position of the pattern P, and the processing device can adjust and calibrate the sensor 210. In the present embodiment, the pattern P may be a pattern in which black squares and white squares are alternately arranged, but the present invention is not limited thereto.
Further, as shown in fig. 1 to 2, the calibration apparatus 100 further includes a controller 170. The controller 170 is electrically connected to the light emitting diode 150 and the power source 160, and configured to control the on/off of the light emitting diode 150. The controller 170 controls the on/off of the light emitting diodes 150, so that the light emitting diodes 150 can be arranged differently on the first surface 141 and the second surface 142 of the film body structure 140, which is helpful for improving the flexibility of the user in adjusting and calibrating the human body scanner 200.
More specifically, the film body structure 140 includes at least one first conductive line 143 and at least one second conductive line 144. As shown in fig. 1, the first conductive traces 143 are disposed on the first surface 141 along the second direction D2, the second direction D2 is substantially perpendicular to the first direction D1, and the light emitting diode 150 is electrically connected to the first conductive traces 143. In the present embodiment, the light emitting diodes 150 are also arranged along the first conductive line 143. The second conductive line 144 is disposed on the first surface 141 substantially along the first direction D1, and the second conductive line 144 is electrically connected to the first conductive line 143 and the power source 160. In other words, the light emitting diode 150 is electrically connected to the power source 160 through the first conductive wire 143 and the second conductive wire 144. In the embodiment, the second conductive line 144 is close to the edge of the film body structure 140, but the invention is not limited thereto.
In addition, the membrane body structure 140 includes at least one support rod 145. As shown in fig. 1, the supporting rod 145 is disposed on the first surface 141 along the second direction D2. In this way, the rigidity of the supporting rod 145 enables the film body structure 140 to be kept flat along the second direction D2, so that the film body structure is not easy to fold or tilt, which is helpful for improving the reliability of the user in adjusting and calibrating the human body scanner 200.
Furthermore, the bracket 130 comprises a metal material, and the supporting rod 145 comprises a rod 146 and at least one magnetic element 147. The rod 146 is disposed on the first surface 141 of the film body structure 140, the magnetic element 147 is disposed at the end of the rod 146, and the position of the magnetic element 147 corresponds to the bracket 130. In this embodiment, the magnetic elements 147 are disposed at opposite ends of the rod 146. The relative position of the membrane structure 140 and the bracket 130 can be further fixed by the magnetic attraction between the magnetic element 147 and the bracket 130, which is helpful for improving the reliability of the user in adjusting and calibrating the human body scanner 200.
Referring to fig. 3, a perspective view of the calibration apparatus 100 of fig. 1 is shown, wherein the calibration apparatus 100 is in an assembling and disassembling process. As shown in fig. 2 to 3, the bracket 130 includes at least one telescopic member 131 and a connecting member 132. One end of the telescopic member 131 is pivoted to the housing 110, and the magnetic element 147 is located corresponding to the telescopic member 131. The connecting member 132 connects one end of the telescopic member 131 far from the housing 110, and the connecting rod 148 of the membrane structure 140 connects the connecting member 132.
During the installation of the calibration device 100, the user first rotates the telescopic member 131 relative to the housing 110 to vertically erect the telescopic member 131, and connects the link 132 to the top end of the telescopic member 131 to form the bracket 130 into the shape of a gantry. The user may then extend the telescoping member 131 upwardly and then pull the membrane structure 140 out of the housing 110 and releasably attach the connecting rod 148 at the end of the membrane structure 140 remote from the housing 110 to the connector 132.
In this embodiment, as shown in fig. 2 to 3, the calibration apparatus 100 further includes at least one first locking member 180. The first locking member 180 is disposed at a position where the telescopic member 131 is connected to the connecting member 132, and the first locking member 180 is configured to fix a relative position of the telescopic member 131 and the connecting member 132 to fix a shape of the bracket 130.
Similarly, in the present embodiment, as shown in fig. 2 to 3, the calibration apparatus 100 further includes at least one second locking member 190. The second locking member 190 is disposed at a position where the telescopic member 131 is connected to the housing 110, and the second locking member 190 is configured to fix a relative position of the telescopic member 131 and the housing 110, so that the stand 130 can stand stably.
During the disassembly process of the calibration apparatus 100, the user first disconnects the connection rod 148 of the membrane structure 140 from the connection member 132, and the membrane structure 140 is received in the housing 110, and then the user retracts the telescopic member 131. Then, for example, the user may release one end of the connecting element 132 from the telescopic member 131, and keep the other end of the connecting element 132 connected to the telescopic member 131, and rotate the connecting element 132 relative to the connected telescopic member 131 to make the connecting element 132 parallel to the connected telescopic member 131, and then the user rotates the telescopic member 131 relative to the housing 110, so that both the telescopic member 131 and the connecting element 132 may be parallel to the housing 110, which enables the calibration apparatus 100 to effectively save space and is beneficial to storing the calibration apparatus 100.
Please refer to fig. 4, which is a perspective exploded view of the housing 110 and the winding drum 121 shown in fig. 1. More specifically, the reel 120 is pivoted in the housing 110, and for simplicity, fig. 4 only shows two ends of the housing 110, and as shown in fig. 4, the reel 120 includes a winding drum 121, a positioning rod 124, a limiting member 1265, a driving portion 127 and a spring 129. The winding drum 121 is connected to the film body structure 140 and adapted to be wrapped by the film body structure 140, and the winding drum 121 has a first connecting end 122 and an opening O opposite to each other, the first connecting end 122 is configured to pivotally connect to the housing 110, and since the first connecting end 122 is pivotally connected to the housing 110, the winding drum 121 can rotate in the rotating direction DR around the axial direction a relative to the housing 110. Furthermore, the bobbin 121 further has at least one protrusion 123, and the protrusion 123 is located inside the bobbin 121 near the opening O. In addition, the positioning rod 124 has a second connecting end 125 and a limiting end 126, the limiting end 126 is located in the winding drum 121, the second connecting end 125 is configured to connect to the housing 110, and the positioning rod 124 does not rotate relative to the housing 110. The position limiting member 1265 is pivotally connected to the position limiting end 126 of the positioning rod 124, so that the position limiting member 1265 can rotate in the rotating direction DR around the axial direction a relative to the positioning rod 124, and the position limiting member 1265 at least abuts against the inner wall of the winding drum 121, so that the position limiting member 1265 can maintain the position of the positioning rod 124 at the center of the winding drum 121. The driving portion 127 is sleeved on and coupled to the positioning rod 124, and is configured to rotate in the rotating direction DR around the axial direction a relative to the positioning rod 124. Moreover, since the driving portion 127 is coupled to the positioning rod 124, when the driving portion 127 rotates along the rotating direction DR around the axial direction a relative to the positioning rod 124, the driving portion 127 moves toward the limiting end 126 (in other embodiments, the driving portion 127 may be far away from the limiting end 126). The driver 127 has at least one recess 128, and the position of the recess 128 corresponds to the protrusion 123 of the spool 121. The spring 129 is sleeved on the positioning rod 124 and connected between the limiting end 126 and the driving portion 127.
That is, when the film body 140 covering the winding drum 121 is pulled out from the housing 110 along the first direction D1, the winding drum 121 is pulled by the film body 140 to rotate around the axial direction a along the rotating direction DR relative to the housing 110, and the protrusion 123 of the winding drum 121 also corresponds to the recess 128 of the driving portion 127, so that the driving portion 127 rotates around the axial direction a along the rotating direction DR along with the winding drum 121 relative to the positioning rod 124. As described above, since the driving portion 127 is sleeved and coupled to the positioning rod 124, the rotation of the driving portion 127 moves the driving portion 127 toward the position-limiting end 126 (in other embodiments, the driving portion 127 may be away from the position-limiting end 126), so that the spring 129 connected between the position-limiting end 126 and the driving portion 127 is compressed (in other embodiments, the spring 129 may be elongated) and stores elastic potential energy. In this way, after the calibration apparatus 100 is installed, the film body structure 140 is pulled by the spring 129, so that the film body structure 140 can be kept flat along the first direction D1 and is not easy to fold or tilt, which is helpful for improving the reliability of the user in adjusting and calibrating the body scanner 200.
As described above, during disassembly of the calibration apparatus 100, the user disconnects the connecting rod 148 of the membrane structure 140 from the connecting member 132. When the connection between the connecting rod 148 of the film structure 140 and the connecting member 132 is released, the elastic energy stored in the spring 129 is released, so that the driving portion 127 rotates relative to the positioning rod 124, and the protrusion 123 corresponding to the recess 128 of the driving portion 127 is also driven, so that the winding drum 121 rotates along with the driving portion 127, which facilitates the film structure 140 to be recovered into the housing 110 and to cover the winding drum 121. It should be noted that, as mentioned above, the supporting bar 145 is disposed on the first surface 141 along the second direction D2, and therefore, the supporting bar 145 does not obstruct the process of wrapping the film body structure 140 around the roll 121.
Fig. 5 is a schematic perspective view illustrating an application of the calibration apparatus 100 according to another embodiment of the invention. In the present embodiment, as shown in fig. 5, the housing 110 of the calibration apparatus 100 can be disposed above the body scanner 200, and the membrane structure 140 is pulled out from top to bottom when the calibration apparatus 100 is used. Thus, the calibration apparatus 100 can be used more flexibly by different configurations of the calibration apparatus 100.
In summary, the technical solutions disclosed in the above embodiments of the present invention have at least the following advantages:
