The present disclosure relates to a mobile x-ray imaging apparatus, and more particularly, to a mobile x-ray imaging apparatus having an improved structure to reinforce security of an x-ray detector.
An x-ray imaging apparatus is an apparatus using x-rays to obtain an image of an inside of an object. An x-ray imaging apparatus may irradiate an object with x-rays and detect x-rays that have passed through the object to form an image of an inside of the object with a non-invasive method. A medical x-ray imaging apparatus may be used in diagnosing an injury, a disease, or the like that cannot be diagnosed from outside.
A typical x-ray imaging apparatus has an x-ray source and an x-ray detector fixed at a predetermined space. Consequently, a patient has to move to an examination room in which an x-ray imaging apparatus is disposed to perform x-ray imaging.
However, because it is difficult to perform x-ray imaging using a typical x-ray imaging apparatus in a case of a patient having mobility difficulties, a mobile x-ray imaging apparatus capable of performing x-ray imaging regardless of location has been developed.
Because a mobile x-ray imaging apparatus has an x-ray source mounted at a movable main body and uses a portable x-ray detector, x-ray imaging may be performed by directly going to a patient having mobility difficulties.
One or more x-ray detectors may be stored in a mobile x-ray imaging apparatus. Due to a characteristic of a mobile x-ray imaging apparatus being usable in various locations, there are concerns regarding a theft or security problem. Particularly, the one or more x-ray detectors are more vulnerable to a theft or security problem due to being portable.

As illustrated in
The one or more locking units 200 may further include one or more rotating members 220. A pressing force of the pressing member 210 may be directly transmitted to the one or more rotating members 220. Since elements configured to mechanically connect the pressing member 210 to the one or more rotating members 220 may be omitted when the one or more locking units 200 are designed so that the pressing force of the pressing member 210 may be directly transmitted to the one or more rotating members 220 as described above, miniaturization and structural simplification of the one or more locking units 200 may be realized.
The one or more rotating members 220 may be provided to rotate and protrude toward an inside of the one or more slots 110 and 120. For example, a rotating member 220 of the first locking unit 200a may rotate and protrude toward the inside of the first slot 110. A rotating member 220 of the second locking unit 200b may rotate and protrude toward the inside of the second slot 120. The one or more rotating members 220 may rotate about a rotation shaft 229 configured to extend in a second direction B. The rotation shaft 229 may pass through the one or more rotating members 220 in the second direction B. The first direction A and the second direction B may be perpendicular to each other.
Each of the one or more rotating members 220 may include a pressing portion 221 provided to be pressed by the pressing member 210.

Each of the one or more rotating members 220 may further include a rod-corresponding surface 225 configured to face a rotation limiting unit 230. Specifically, each of the one or more rotating members 220 may further include the rod-corresponding surface 225 configured to face a rod 231. One end portion of the rod 231 facing the rod-corresponding surface 225 may move along the rod-corresponding surface 225 when the one or more rotating members 220 rotate. A locking groove 227 configured to limit rotation of the one or more rotating members 220 by the one end portion of the rod 231 being inserted thereinto may be formed to be recessed at the rod-corresponding surface 225.
The rod-corresponding surface 225 may include a first portion 225a disposed in front of a second portion 225b in the direction R in which the one or more rotating members 220 rotate by being pressed by the pressing member 210 (see

The rotation limiting unit 230 may further include a solenoid 233 coupled to the rod 231 to adjust movement of the rod 231 according to an electrical signal. The solenoid 233 may be connected via a cable 239 to a controller configured to control whether the solenoid 233 is operated. The solenoid 233 may mostly operate during a process in which the one or more slots 110 and 120 are being unlocked. That is, when a user inputs a command for unlocking the one or more slots 110 and 120, the rod 231 moves downward in the first direction A when the solenoid 233 is operated. Accordingly, the one end portion of the rod 231 is detached from the locking groove 227, and the one or more rotating members 220 are restored to a state of before being pressed by the pressing member 210. Consequently, the one or more slots 110 and 120 are unlocked. A user may input a password or use a radiofrequency (RF) card to command the one or more slots 110 and 120 to be unlocked.
The rotation limiting unit 230 may further include a casing 234 configured to have the rod 231 and the solenoid 233 mounted therein. A rod guide 235 may be formed at one sidewall 234a of the casing 234. The rod guide 235 may have a shape that extends in the first direction A to limit movement of the rod 231. A stopper 232 configured to protrude from the rod 231 may be formed at the rod 231. Movement of the rod 231 may be limited by interference between the stopper 232 and the rod guide 235. The stopper 232 formed to protrude from the rod 231 may vertically move in the first direction A and be coupled to the rod guide 235 to limit vertical movement of the rod 231.
The one or more locking units 200 may further include a connecting member 240 configured to connect the pressing member 210 to the rotation limiting unit 230.

The pressing member 210 may be restored to a state of before being pressed by a restoration force of the first elastic member 280.
The one or more locking units 200 may further include a second elastic member 290.

When described according to another aspect, the protrusion 221a may extend from the pressing portion 221 of each of the one or more rotating members 220 in the second direction B to face the plurality of ribs 252 of the support member 250 to which the one end portion of the second elastic member 290 is fixed. When the one or more rotating members 220 are pressed by the pressing member 210, the second elastic member 290 may be contracted. Conversely, when the one or more rotating members 220 are not pressed by the pressing member 210, the second elastic member 290 may be relaxed. The one or more rotating members 220 may be restored to a state of before being pressed by a restoration force of the second elastic member 290.
