Referring to fig. 1 to 5, in an embodiment, the power cord retracting device 100 includes a mounting base 110, a spindle 120, a winding frame 130, a power cord 140, a rotating reset element 150, a conductive slip ring 160, and a self-locking mechanism 170.
The mounting base 110 serves as a support structure for the entire device, and may be a bracket-like structure or a housing-like structure. For example, referring to fig. 1 to 3, in one embodiment, the mounting base 110 includes a base 111 and a top cover 112. The base 111 and the top cover 112 enclose a mounting cavity. The main shaft 120, the spool stand 130, the rotary return 150, the conductive slip ring 160, and the self-locking mechanism 170 are all mounted within the mounting cavity. The mounting base 110 not only supports the respective components, but also serves as a housing to protect the components from external force. In one embodiment, the base 111 and the top 112 may be sealingly engaged, and may generally form a closed structure except for the necessary openings (such as the power cord outlet 113 shown in FIG. 2), to reduce the possibility of foreign objects entering the interior of the device.
Referring to fig. 3 to 5, the spindle 120 is mounted on the mounting base 110. The spindle 120 itself is fixedly connected to the mounting base 110. For example, in one embodiment, as shown in FIGS. 4 and 5, the spindle 120 is secured at each end to the base 111 and the top cover 112, respectively. The main shaft 120 may be threaded at both ends to be fixed with the base 111 and the top cover 112 by corresponding lock nuts 121. Of course, the spindle 120 may be fixed by other means, such as bonding, welding, etc.
With continued reference to fig. 3-5, the spool 130 is rotatably mounted on the spindle 120. The winding frame 130 is depressed at the middle thereof so that the power cord 140 is wound around the winding frame 130. When the power cord 140 needs to be pulled out, the power cord 140 can be pulled directly to drive the spool stand 130 to rotate, so as to pay out the power cord 140.
The power cord 140 has a power plug 141, and the power plug 141 is used for connecting to a power supply outlet to supply power to the device. Referring to fig. 1 and 2, when the mounting base 110 is of a housing-like structure, the mounting base 110 has a power cord outlet 113, and one end of the power plug 141 extends out of the power cord outlet 113, so that the user can pull out the power cord 140.
The rotary restoring member 150 is mounted on the main shaft 120 or the mounting base 110. The spool 130 is engaged with the rotary restoring member 150, and drives the rotary restoring member 150 to deform when the spool 130 rotates. A rotational restoring force is provided to the spool 130 by the rotational restoring member 150 to drive the spool 130 to be rotationally restored when the spool 130 is released.
Referring to fig. 3 and 4, in the illustrated embodiment, the rotary restoring member 150 is mounted on the main shaft 120, and a supporting plate 151 may be disposed on the main shaft 120 to support the rotary restoring member 150. The rotary restoring member 150 has one end fixed to the main shaft 120 and the other end directly or indirectly engaged with the spool 130. The rotational reset 150 includes, but is not limited to, a coil spring. The spool 130 can be driven to reset by the deformation of the coil spring.
Referring to fig. 3 to 5, the conductive slip ring 160 includes a stator assembly 161 and a rotor assembly 162 that is rotatable relative to the stator assembly 161. Stator assembly 161 is fixedly mounted to mounting base 110, and rotor assembly 162 is coupled to spool 130 to rotate with spool 130. Stator assembly 161 and rotor assembly 162 are electrically connected. The rotor assembly 162 is electrically connected to the power cord 140, and the stator assembly 161 is connected to other power consuming units within the device. The specific structure of the rotor assembly 162 and the stator assembly 161 can adopt the structure of the existing conductive slip ring 160, and will not be described again.
The conductive slip ring 160 employs multiple sets, multiple contacts and a sealing structure, thereby greatly improving the contact reliability. Meanwhile, the conductive sliding ring 160 has a compact structure and a small volume, so that the whole volume of the device is smaller, and the device can be applied to a scene with a small space.
Referring to fig. 4, in one embodiment, the spindle 120 has a through hole 122 therein. The stator assembly 161 is fixedly mounted on the main shaft 120. The attachment end 1611 of the stator assembly 161 extends out of the through hole 122 in the main shaft 120. The connection terminal 1611 is used to electrically connect to an electrical unit in the device.
Referring to fig. 3 to 5, the self-locking mechanism 170 is used to lock and release the spool 130. When the power cord 140 is pulled out, the power cord 140 can be locked at a desired length position by the self-locking mechanism 170 as needed. For example, the self-locking mechanism 170 can be changed to a locked state by pulling the power cord 140 once and then releasing it. When the power cord 140 is not in use, the self-locking mechanism 170 can be unlocked, the power cord 140 and the spool 130 are released, and the spool 130 is reset under the driving of the rotary reset piece 150.
In one embodiment, the self-locking mechanism 170 includes a ratchet and pawl mechanism mounted between the mount 110 and the spool 130 for locking and releasing the spool 130. In one embodiment, the ratchet-pawl mechanism has self-locking and self-unlocking features to facilitate the extension and retraction of the power cord 140. That is, when the power cord 140 is pulled once, the ratchet mechanism will lock the spool 130 and the power cord 140 at the current position after the external force disappears, and when the power cord 140 is pulled once again, the ratchet mechanism is unlocked, and the power cord 140 can be automatically retracted along with the spool 130.
Referring to fig. 3 and 5, in one embodiment, the ratchet-pawl mechanism includes a locking plate 171, a pawl 172, a pawl holder 173, and a return spring 174. The locking plate 171 is mounted on the spool 130 to rotate together with the spool 130. The locking disc 171 has a ratchet wheel 175. Pawl mount 173 is mounted to mount 110 and pawls 172 are pivotally mounted to pawl mount 173, such as on posts 1731 of pawl mount 173. And the pawl 172 has a first end 1721 and a second end 1722 distributed on either side of its axis of rotation. First end 1721 is connected to pawl mount 173 by return spring 174. The return spring 174 is used to return the pawl 172. The second end 1722 of the pawl 172 extends toward the ratchet wheel 175 and engages the ratchet wheel 175. A limiting protrusion 1732 is provided at one side of the first end 1721 of the pawl 172, and the limiting protrusion 1732 is provided on the pawl holder 173 to limit the first end 1721 from rotating toward the limiting protrusion 1732 side. The pawl 172 may move to a side opposite to the limit protrusion 1732 when the power cord 140 is pulled out, and the reel 130 is reset by the rotating reset member 150 when the power cord 140 is stopped being pulled. At this time, the pawl 172 should rotate to the side of the limiting protrusion 1732, but the pawl 172 cannot rotate any more due to the blocking of the limiting protrusion 1732, so that the pawl 172 also prevents the ratchet wheel 175, the locking plate 171 and the spool 130 from rotating any more, and the power cord 140 is locked at the current length position. When the power cord 140 needs to be recovered, the ratchet-pawl mechanism can be unlocked, so that the spool 130 can move freely.
Further, referring to fig. 3 to 5, in an embodiment, the pawl holder 173 can be locked on the base 111 of the mounting base 110 by screws.
Further, referring to fig. 3 and 4, in one embodiment, the rotating reset element 150 and the spool 130 are sleeved on the spindle 120. The locking plate 171 is disposed on the spindle 120 and fixedly connected to the spool stand 130. The ratchet 175 is fixedly connected to the lock plate 171. The fixing device can be fixed through corresponding screws, and can also be fixed through other modes.
Further, referring to fig. 6, in an embodiment, the mobile medical device of the present embodiment includes a control unit and a power circuit, the stator assembly 161 is electrically connected to the power circuit, and the power circuit is electrically connected to the control unit. In this embodiment, the power cord 140 directly supplies power to the control unit.
