[0002] Medical imaging equipment plays an increasingly important role in the diagnosis and treatment of diseases. Medical imaging equipment includes imaging devices and medical beds. In clinical operations, in order to facilitate scanning and imaging of patients, a movable medical bed is used to transport the patient to the imaging device, and then the patient is moved to the imaging channel by a movable bed board for imaging.

[0003] Most movable medical beds have a docking structure, through which the medical bed and the imaging device are electrically and / or data connected and the medical bed is precisely positioned, so that the patient on the bed can be accurately positioned in the imaging channel.

[0004] In the prior art, some technical solutions use hydraulic drive to achieve the docking between the docking structure of the medical bed and the receiving structure of the imaging device. However, if the docking process of the hydraulic drive is not fully executed, problems will occur. In addition, the hydraulic system is expensive and bulky, and the operating comfort is poor. Summary of the invention

[0009] The electric drive assembly is arranged inside the supporting body, and the electric drive assembly is connected to the mounting seat and is used to drive the mounting seat so that the supporting body and the imaging device are docked.

[0010] In one embodiment, the docking structure further includes a support portion and a bedside connector, the support portion is fixedly connected to the support body, the mounting seat is located inside the support portion, and the bedside connector is fixedly connected to the front end of the support portion.

[0011] In one embodiment, the docking structure further includes a guide portion and a support plate, wherein the bottom end of the support plate is connected to the support body, and the guide portion is connected to the top end of the support plate and is located above the bedside connector.

[0012] In one embodiment, the docking structure also includes a tensioning assembly, which includes a connecting rod and two pull rods, the two ends of the connecting rod are respectively connected to the upper ends of the two pull rods, the lower ends of the two pull rods are respectively connected to the tensioning parts, and the pull rod is rotatably connected to the mounting seat.

[0013] In one embodiment, the upper end of the support portion has a stop portion, the upper end of the tensioning assembly is located at the rear side of the stop portion, and the stop portion at least partially overlaps with the projection of the tensioning assembly in the first direction.

[0014] In one embodiment, avoidance holes are respectively provided on both sides of the support portion; the docking structure further includes a rotating shaft, and the pull rod is rotatably connected to the mounting seat via the rotating shaft;

[0015] Wherein, the rotating shaft is penetrated through the mounting seat, and two ends of the rotating shaft respectively extend out of the avoidance holes on both sides of the supporting part and are connected to the pull rod.

[0016] A medical imaging device comprises an imaging device and a medical bed as described in any one of the above embodiments, wherein the imaging device comprises an imaging body and a receiving structure, wherein the receiving structure is arranged on one side of the imaging body along a first direction; the receiving structure comprises: a docking base, an imaging side connector and a limiting portion, wherein the imaging side connector and the limiting portion are respectively connected to the docking base.

[0017] A method for docking a medical bed and an imaging device, for docking a medical bed of the medical imaging equipment with the imaging device, the method comprising the following steps:

[0018] Driving the medical bed to move toward the imaging device so that the limiting portion abuts against the tensioning portion, and the tensioning portion changes from the first position to the second position;

[0019] The medical bed is driven to continue to move, the tensioning part passes over the limiting part and returns to the first position from the second position under the action of the elastic part, and the tensioning part is hooked with the limiting part;

[0020] The mounting seat is driven by the electric drive assembly to move the supporting body so as to dock with the imaging device.

[0021] In one embodiment, the step of driving the mounting seat by the electric drive assembly to move the supporting body so as to dock with the imaging device comprises:

[0022] The mounting seat is driven in a direction away from the imaging device by the electric drive assembly, and the hooking state between the tensioning portion and the limiting portion can prevent the mounting seat from moving in a direction away from the imaging device, so that the driving force exerted on the mounting seat reacts on the supporting body, causing the supporting body to move toward the imaging device to complete the docking.

[0023] In one embodiment, when the tensioning portion is hooked with the limiting portion, the signal generator generates an induction signal, and the induction signal triggers the electric drive component to automatically drive the mounting seat, so that the supporting body moves and docks with the imaging device.

[0024] A method for separating a medical bed from an imaging device, for separating the medical bed of the medical imaging equipment from the imaging device, comprises the following steps:

[0025] Driving the medical bed away from the imaging device so that the stopper pushes the tensioning assembly, so that the pull rod rotates to drive the tensioning part to change from the first position to the second position, and the limiting part releases the tensioning part;

[0026] The medical bed is driven to continue to move away so that the bed-side connector on the supporting body is separated from the imaging-side connector of the imaging device, thereby completing the separation of the medical bed from the imaging device.

[0027] In the above-mentioned medical bed, medical imaging equipment, docking method, and detaching method, when the medical bed is docked with the imaging device, the medical bed is first placed on one side of the imaging device along the first direction, and then the medical bed as a whole is moved close to the imaging device along the first direction, so that the tensioning part in the first position relative to the mounting seat moves close to the limiting part along the first direction until the tensioning part abuts against the side of the limiting part away from the imaging subject. In the process of continuing to move the medical bed as a whole close to the imaging device along the first direction, the abutting force of the limiting part on the tensioning part can enable the tensioning part to overcome the elastic force of the elastic part, so that the tensioning part switches from the first position to the second position. The medical bed is then continued to be moved close to the imaging device along the first direction, and the tensioning part in the second position can be moved to the side of the limiting part close to the imaging subject, that is, the tensioning part moves from the side of the limiting part away from the imaging subject to the side of the limiting part close to the imaging subject, so that the tensioning part is restored from the second position to the first position by the restoring force of the elastic part, and the limiting part is hooked with the tensioning part. Since the tensioning part is located on the side of the limiting part close to the imaging subject and is in the first position, the limiting part can prevent the tensioning part from moving in the first direction away from the imaging subject, thereby preventing the mounting seat from moving in the first direction away from the imaging subject. The position of the mounting seat at this time is defined as the reference position. Since the mounting seat cannot move in the direction away from the imaging subject when in the reference position, the mounting seat and the supporting body can be driven by the electric drive assembly to move relative to each other in the first direction, so that the supporting body moves in the first direction toward the imaging subject, thereby achieving docking between the two. The reliable docking of the medical bed and the imaging device is achieved by the electric drive of the electric drive assembly, which reduces the bulkiness and improves the operating comfort compared to the hydraulic assembly.

[0044] Please refer to Figure 1 In one embodiment of the present application, a medical bed 100 is provided, and the medical bed 100 includes: a bed plate 110, a support body 120, a moving wheel 180, and a docking structure 130. The bed plate 110 is connected to the top of the support body 120, and the moving wheel 180 is connected to the bottom of the support body 120. The docking structure 130 is arranged at the front end of the support body 130. The docking structure 130 is used to dock with the receiving structure 220 of the imaging device 200.

[0045] Recombination Figure 2 The imaging device 200 includes an imaging body 210 and a receiving structure 220 disposed on the imaging body 210. The receiving structure 220 is located on one side of the imaging body 210 along the first direction X. The receiving structure 220 includes: a docking base 221, an imaging side connector 222 and a limiter 223. The docking base 221 is disposed on the imaging body 210, and the imaging side connector 222 and the limiter 223 are respectively disposed on the docking base 221. The imaging body 210 has an imaging channel for allowing the bed board 110 and the object to be inspected thereon to enter. The imaging device 200 is, for example, a computed tomography device (CT), a positron emission tomography device (PET), a magnetic resonance imaging device (MRI), and a combination thereof (such as PET-CT, PET-MR), etc.

[0046] Recombination Figures 3 to 7The docking structure 130 includes: a bedside connector 131, a mounting seat 132, an electric drive assembly, a tensioning portion 134 and an elastic portion 135. The tensioning portion 134 is connected to the mounting seat 132 and has a first position and a second position relative to the mounting seat 132. An elastic portion 135 is provided between the tensioning portion 134 and the mounting seat 132, and the tensioning portion 134 can move to the first position or the second position under the action of an elastic force. When the tensioning portion 134 is in the first position, the limiting portion 223 blocks the tensioning portion 134 along a first direction X, and the first direction X is parallel to the axial direction of the imaging channel of the imaging subject 210. When the tensioning portion 134 is in the second position, the limiting portion 223 releases the blocking of the tensioning portion 134. The tensioning portion 134 and the mounting seat 132 are respectively connected to the elastic portion 135, and the elastic portion 135 is used to drive the tensioning portion 134 to switch from the second position to the first position; when the tensioning portion 134 abuts against the side of the limiting portion 223 away from the imaging body 210, the abutting force of the limiting portion 223 on the tensioning portion 134 can enable the tensioning portion 134 to overcome the elastic force of the elastic portion 135, so that the tensioning portion 134 can switch from the first position to the second position. The mounting seat 132 is movably connected to the support body 120 along the first direction X. The electric drive component is arranged inside the support body 120, and the electric drive component is connected to the mounting seat 132 and is used to drive the mounting seat 132, so that the support body 120 is docked with the imaging device 200.

[0047] When the medical bed 100 is docked with the imaging device 200, the medical bed 100 is first placed on one side of the imaging device 200 along the first direction X, and then the medical bed 100 is moved as a whole along the first direction X close to the imaging device 200, so that the tensioning portion 134 in the first position relative to the mounting seat 132 moves along the first direction X close to the limiting portion 223 until the tensioning portion 134 abuts against the side of the limiting portion 223 away from the imaging body 210. When the medical bed 100 continues to be moved as a whole along the first direction X close to the imaging device 200, the abutting force of the limiting portion 223 on the tensioning portion 134 can enable the tensioning portion 134 to overcome the elastic force of the elastic portion 135, so that the tensioning portion 134 switches from the first position to the second position. The medical bed 100 is then moved along the first direction X close to the imaging device 200, and the tensioning portion 134 in the second position can be moved to the side of the limiting portion 223 close to the imaging subject 210, that is, the tensioning portion 134 moves from the side of the limiting portion 223 away from the imaging subject 210 to the side of the limiting portion 223 close to the imaging subject 210, so that the tensioning portion 134 is restored from the second position to the first position (at this time, the medical bed 100 is in the Figure 5As the tensioning portion 134 is located on the side of the limiting portion 223 close to the imaging subject 210 and is in the first position, the limiting portion 223 can prevent the tensioning portion 134 from moving in the first direction X away from the imaging subject 210, thereby preventing the mounting seat 132 from moving in the first direction X away from the imaging subject 210. The position of the mounting seat 132 at this time is defined as the reference position. As the mounting seat 132 cannot move in the direction away from the imaging subject 210 when in the reference position, the mounting seat 132 and the support body 120 can be driven by the electric drive assembly to move relative to each other in the first direction X, so that the support body 120 moves in the direction close to the imaging subject 210, and the support body 120 drives the bedside connector 131 to move in the direction close to the imaging side connector 222, so that the bedside connector 131 and the imaging side connector 222 are connected. Among them, since the tensioning part 134 is located on the side of the limiting part 223 close to the imaging subject 210 and is in the first position, it can be blocked by the limiting part 223, thereby preventing the medical bed 100 from moving away from the imaging subject 210, that is, preventing the bedside connector 131 from moving in the direction of separating from the imaging side connector 222, so that the bedside connector 131 and the imaging side connector 222 can be reliably docked. The medical bed and the imaging device are electrically reliably docked by the electric drive of the electric drive assembly, which reduces the bulkiness and improves the operating comfort compared to the hydraulic assembly.

[0048] It can be understood that the bed board 110 is movably connected to the support body 120 along the first direction X. After the bed side connector 131 and the imaging side connector 222 are docked, the bed board 110 can be moved along the first direction X to drive the object to be inspected into the imaging channel of the imaging device 200.

[0049] refer to Figure 3 and Figure 4 In one embodiment, the docking structure 130 also includes a support portion 140 and a bedside connector 131, the support portion 140 is fixedly connected to the support body 120, the mounting seat 132 is located in the support portion 140, the bedside connector 131 is fixedly connected to the front end of the support portion 140, and the bedside connector 131 is used to be plugged into the imaging side connector 222 of the imaging device 200.

[0050] Specifically, the support portion 140 includes two side panels spaced apart, namely, a first side panel 140a and a second side panel 140b. The mounting seat 132 is located between the first side panel 140a and the second side panel 140b. Both ends of the bed side connector 131 are fixedly connected to the front end of the first side panel 140a and the front end of the second side panel 140b, respectively.

[0051] The docking of the bedside connector 131 and the imaging side connector 222 is used to achieve conduction of one or more arbitrary combinations of electrical signals, optical signals, radio frequency, liquid, and electrical energy between the medical bed 100 and the imaging device 200.

[0052] One of the bedside connector 131 and the imaging side connector 222 is a male connector, and the other is a female connector. In this embodiment, the bedside connector 131 is a male connector, and the imaging side connector 222 is a female connector.

[0053] Specifically, the female connector includes a socket 2221, and the male connector includes a plug 1311. The plug 1311 is plug-in-fitted with the socket 2221.

[0054] Furthermore, a guide sleeve 2222 is provided on the socket 2221, and the male connector also includes a guide pin 1312. The guide sleeve 2222 is plugged into and matched with the guide pin 1312 to guide the docking direction of the male connector and the female connector.

[0055] In one embodiment, the tensioning portion 134 may be a hook, which is located on a side of the limiting portion 223 close to the imaging subject 210 and is in the first position, so that the limiting portion 223 can be hooked in a direction away from the imaging subject 210, thereby enabling the limiting portion 223 to be reliably matched with the tensioning portion 134. The elastic portion 135 may be a coil spring, an elastic block, etc.

[0056] Please refer to Figures 3 to 7 In one embodiment, the medical bed 100 includes a guide rail 170 arranged on the support body 120, and the mounting seat 132 cooperates with the guide rail 170 to move along the first direction X, so that the guide rail 170 can guide the mounting seat 132 and the support body 120 to move relative to each other along the first direction X.

[0057] refer to Figure 2 In one embodiment, the docking base 221 has a accommodating cavity, the imaging side connector 222 and the limiting portion 223 are located in the accommodating cavity, and the docking base 221 has an opening at one end away from the imaging body 210, and the opening is used for the docking structure 130 to enter, so that the bed side connector 131 can enter the accommodating cavity to dock with the imaging side connector 222, and the tensioning portion 134 can enter the accommodating cavity to cooperate with the limiting portion 223.

[0058] Please refer to Figures 3 to 7In one embodiment, the docking structure 130 further includes a guide portion 160 and a support plate 162, the bottom end of the support plate 162 is connected to the support body 120, and the guide portion 160 is connected to the top end of the support plate 162 and is located above the bedside connector 131. The receiving structure 220 includes a guide groove 2211 provided on the docking base 221. The guide portion 160 is used to cooperate with the guide groove 2211 of the imaging device 200 to move along the first direction X, and the guide groove 2211 is used to guide the guide portion 160 to move along the first direction X, so that the support body 120 can accurately move along the first direction X.

[0059] Specifically, see Figures 3 to 7 The docking structure 130 includes two support plates 162 spaced apart along the second direction Y, and both ends of the guide portion 160 along the second direction Y are respectively connected to the top ends of the two support plates 162 .

[0060] Please refer to Figure 2 In one embodiment, the receiving structure 220 includes a stopper 224, which is disposed on the docking base 221. The stopper 224 is used to block the mounting seat 132 to define a reference position of the mounting seat 132. When in the reference position, the mounting seat 132 is located at a side of the stopper 224 of the imaging device 200 away from the imaging subject 210 along the first direction X and abuts against the stopper 224. The tensioning portion 134 is located at a side of the limiting portion 223 close to the imaging subject 210 and is in the first position.

[0061] Specifically, the medical bed 100 as a whole moves along the first direction X close to the imaging device 200 until the abutment force of the limit portion 223 causes the tensioning portion 134 to switch from the first position to the second position, and then the medical bed 100 continues to move along the first direction X close to the imaging device 200, and the tensioning portion 134 in the second position can move to the side of the limit portion 223 close to the imaging subject 210, and the tensioning portion 134 is restored from the second position to the first position by the restoring force of the elastic portion 135. At this time, the position of the mounting seat 132 is the reference position. At the same time, the mounting seat 132 abuts against the side of the stop portion 224 of the imaging device 200 away from the imaging subject 210 along the first direction X, so that the mounting seat 132 can be limited to the reference position. In this way, as the medical bed 100 continues to move closer to the imaging body 210, the stop portion 224 is used to conveniently determine the moment when the mounting seat 132 reaches the reference position, and then conveniently start the electric drive component to drive the mounting seat 132 and the support body 120 to move relative to each other along the first direction X, so that the support body 120 drives the bed side connector 131 to dock with the imaging side connector 222.

[0062] like Figure 2As shown, in one embodiment, the stop portion 224 is located in the accommodating cavity, and the mounting seat 132 can enter the accommodating cavity from the opening of the end of the docking base 221 away from the imaging body 210 , thereby cooperating with the stop portion 224 .

[0063] Please refer to Figures 3 to 7 In one embodiment, the docking structure 130 further includes a signal generator 150, which is connected to the front end of the mounting seat 132. When the mounting seat 132 moves along the first direction X close to the imaging subject 210, when the tensioning portion 134 moves to the side of the limiting portion 223 close to the imaging subject 210 and is in the first position (that is, when the mounting seat 132 is in the reference position), the signal generator 150 can generate a sensing signal. At this time, the sensing signal indicates that the mounting seat 132 has reached the reference position, which facilitates determining the moment when the mounting seat 132 reaches the reference position.

[0064] In one embodiment, the sensing signal triggers the electric drive assembly to drive the mounting seat 132 and the support body 120 to move relative to each other along the first direction X, so that the support body 120 drives the bedside connector 131 to dock with the imaging side connector 222. In this way, the action of the electric drive assembly can be automatically triggered by the sensing signal, so that when the mounting seat 132 reaches the reference position, the bedside connector 131 automatically docks with the imaging side connector 222.

[0065] Please refer to Figures 3 to 7 In one embodiment, the signal generator 150 is a sensor. A trigger portion is provided on the docking base 221. When the mounting base 132 moves along the first direction X close to the imaging subject 210, when the tensioning portion 134 moves to the side of the limiting portion 223 close to the imaging subject 210 and is in the first position, that is, when the mounting base 132 is in the reference position, the trigger portion triggers the sensor so that the sensor generates the above-mentioned sensing signal. The sensor is, for example, a photoelectric sensor.

[0066] In other embodiments, the docking structure may include a prompting part, and the induction signal triggers the prompting part to send a prompting signal, so that the electric drive component can be manually started according to the prompting signal. In this way, it is convenient to remind the installation seat to reach the reference position through the prompting signal. Specifically, the prompting part includes, for example, a sound prompter (such as a buzzer), and the prompting signal includes a sound signal. The prompting part includes, for example, a prompting light, and the prompting signal includes a light signal.

[0067] Please refer to Figures 3 to 7In one embodiment, the tensioning portion 134 is connected to the mounting seat 132 for rotation around an axis of a second direction Y. The second direction Y may be perpendicular to the first direction X. The tensioning portion 134 switches between the first position and the second position by rotating relative to the mounting seat 132, that is, when in the first position and the second position, the tensioning portion 134 is in different rotational positions relative to the mounting seat 132. When the tensioning portion 134 is located on the side of the limiting portion 223 close to the imaging subject 210 and is in the first position, the elastic force of the elastic portion 135 on the tensioning portion 134 causes the tensioning portion 134 to have a tendency to rotate, so that the tensioning portion 134 can have a tangential abutment force on the limiting portion 223 in the first direction X, thereby making the tensioning portion 134 and the limiting portion 223 more reliably matched.

[0068] In this embodiment, the elastic portion 135 may also be a torsion spring, which is disposed at the rotational connection between the tensioning portion 134 and the mounting seat 132 .

[0069] Please refer to Figures 3 to 7 In one embodiment, the docking structure 130 also includes a tensioning assembly, which includes a connecting rod 137 and two pull rods 136. The two ends of the connecting rod 137 are respectively connected to the upper ends of the two pull rods 136. The lower ends of the two pull rods 136 are respectively connected to the tensioning parts 134. The pull rod 136 is rotatably connected to the mounting seat 132.

[0070] Please refer to Figures 3 to 7 In one embodiment, avoidance holes 142 are respectively provided on both sides of the support portion 140. The docking structure 130 further includes a rotating shaft 138, which is passed through the mounting seat 132, and both ends of the rotating shaft 138 extend out of the avoidance holes 142 on both sides of the support portion 140. Two pull rods 136 are respectively connected to both ends of the rotating shaft 138, and are rotatably connected to the mounting seat 132 through the rotating shaft 138. The rotating shaft 138 can move along the first direction X in the avoidance hole 142, thereby allowing the mounting seat 132 to move relative to the support body 120 along the first direction X.

[0071] Specifically, the first side plate 140 a and the second side plate 140 b are respectively provided with avoidance holes 142 , that is, avoidance holes 142 on both sides of the support portion 140 .

[0072] Please refer to Figures 3 to 7 In one embodiment, the electric drive assembly includes a motor 1331 and a transmission assembly 1332. The motor 1331 is fixedly connected to the support body 120, the input end of the transmission assembly 1332 is connected to the motor 1331, and the output end of the transmission assembly 1332 is connected to the mounting seat 132. The transmission assembly is used to convert the rotational motion output by the motor into linear motion, so that when the output shaft of the motor 1331 rotates, the mounting seat 132 can be driven to move relative to the support body 120 along the first direction X through the transmission assembly 1332.

[0073] In the embodiment of the present application, when the mounting seat 132 is in the reference position, the mounting seat 132 is driven by the electric drive assembly to move relative to the support body 120 in a direction away from the imaging body 210. However, when the mounting seat 132 is in the reference position (due to the cooperation between the limit portion 223 and the tensioning portion 134), it cannot move in a direction away from the imaging body 210, so that the support body 120 moves relative to the mounting seat 132 in a direction close to the imaging body 210 through relative movement, thereby driving the bed-side connector 131 to dock with the imaging-side connector 222.

[0074] In one embodiment, the transmission assembly is a screw-nut mechanism, the screw is connected to the output shaft of the motor, the nut is threadedly matched with the screw, and the nut is fixedly connected to the mounting seat 132 .

[0075] In other embodiments, the transmission assembly may also be a crank slider mechanism, etc.

[0076] However, sometimes due to unexpected circumstances and other reasons, the medical bed loses power, and the motor 1331 loses power, which makes it impossible to use the electric docking method to dock the medical bed with the imaging device. The above-mentioned medical bed in the embodiment of the present application can also be docked with the imaging device by manual docking. Specifically, when the mounting seat 132 reaches the reference position, the limit portion 223 can block the tensioning portion 134 from moving in the first direction X away from the imaging body 210, thereby blocking the mounting seat 132 from moving in the first direction X away from the imaging body 210. At this time, since the motor 1331 loses power, the transmission component 1332 is not controlled and can move freely. Therefore, the support body 120 can be manually pushed in the direction close to the imaging body 210. Through the movement of the transmission component 1332, it can be achieved that when the mounting seat 132 does not move, the support body 120 drives the bed side connector 131 to move in the direction close to the imaging side connector 222, and the bed side connector 131 is docked with the imaging side connector 222.

[0077] Specifically, when the transmission assembly is a screw-nut mechanism, the screw is connected to the output shaft of the motor, and the nut is threadedly matched with the screw. The nut is fixedly connected to the mounting seat 132. When the motor 1331 loses power, the screw and the output shaft of the motor can rotate freely. When the mounting seat 132 reaches the reference position, the limit portion 223 can block the tensioning portion 134 from moving in the first direction X away from the imaging body 210, thereby blocking the mounting seat 132 from moving in the first direction X away from the imaging body 210. At this time, when the mounting seat 132 and the nut are stationary, the support body 120 is manually pushed in the direction close to the imaging body 210, and the screw rotates relative to the nut and moves in the first direction X, so that the support body 120 can drive the bed side connector 131 to move in the direction close to the imaging side connector 222 for docking. That is, manual docking is achieved.

[0078] like Figures 3 to 7 As shown, in one embodiment, the medical bed 100 further includes a stopper 141. With the help of the stopper 141, the medical bed 141 and the imaging device 200 can be electrically separated. When the support body 120 moves relative to the mounting seat 132 along the first direction X to drive the bedside connector 131 to move in the direction of separating from the imaging side connector 222, the stopper 141 can drive the tensioning part 134 to switch from the first position to the second position. When the bedside connector 131 of the medical bed 100 is separated from the imaging side connector 222 of the imaging device 200, the support body 120 is moved in a direction away from the imaging body 210. Specifically, the support body 120 can be driven to move by a driving mechanism (such as an electric driving mechanism) equipped by the support body 120 itself.

[0079] When the bed-side connector 131 and the imaging-side connector 222 are connected, the limiting portion 223 blocks the tensioning portion 134 from moving away from the imaging subject 210 along the first direction X, thereby blocking the mounting seat 132 from moving away from the imaging subject 210 along the first direction X. Therefore, in the initial stage of the support body 120 moving away from the imaging subject 210, the mounting seat 132 does not move, and the support body 120 and the stopper 141 move relative to the mounting seat 132 at the same time, so that the stopper 141 drives the tensioning portion 134 to move, and then the tensioning portion 134 overcomes the elastic force of the elastic portion 135 and switches from the first position to the second position. At this time, the tensioning portion 134 is not blocked by the limiting portion 223, so that the tensioning portion 134 and the mounting seat 132 can move in the direction away from the imaging subject 210, and then when the supporting body 120 continues to move away from the imaging subject 210, the mounting seat 132 moves synchronously with it, and the bed side connector 131 is separated from the imaging side connector 222, thereby realizing the electric separation of the medical bed 100 from the imaging device 200.

[0080] In one embodiment, the upper end of the support portion 140 has a stopper 141 , the upper end of the tensioning assembly is located behind the stopper 141 , and the stopper 141 at least partially overlaps with the projection of the tensioning assembly in the first direction X.

[0081] Since the support portion 140 is fixedly connected to the support body 120, when the support body 120 is driven to move in a direction away from the imaging body 210, the support body 120, the support portion 140 and the stopper 141 move synchronously. In addition, since the upper end of the tensioning assembly is located at the rear side of the stopper 141, and the stopper 141 at least partially overlaps with the projection of the tensioning assembly in the first direction X, the stopper 141 can push the tensioning assembly to rotate the pull rod 136 during the synchronous movement with the support body 120, thereby driving the tensioning portion 134 to overcome the elastic force of the elastic portion 135 and switch from the first position to the second position. At this time, the tensioning portion 134 is not blocked by the limiting portion 223, so that the tensioning portion 134 and the mounting seat 132 can move in the direction away from the imaging subject 210, and then when the supporting body 120 continues to move away from the imaging subject 210, the mounting seat 132 moves synchronously with it, and the bed side connector 131 is separated from the imaging side connector 222, thereby realizing the electric separation of the medical bed 100 from the imaging device 200.

[0082] Please refer to Figures 3 to 7 In one embodiment, the connecting rod 137 is located at the rear side of the stopper 141, and the projection of the stopper 141 and the connecting rod 137 in the first direction X overlap. Therefore, when the stopper 141 moves synchronously with the support body 120, it can push the connecting rod 137 to rotate the pull rod 136. The length direction of the connecting rod 137 is along the second direction Y.

[0083] Please refer to Figures 3 to 7 , medical beds 100 Figure 6 In the state shown, the bedside connector 131 and the imaging side connector 222 are connected to each other, and the end of the connecting rod 137 away from the tensioning part 134 is spaced apart from the stopper 141 in the first direction X. Figure 6 The status shown is Figure 7 When the state shown moves, that is, when the support body 120 drives the bed-side connector 131 to move in the direction of disengaging from the imaging-side connector 222, that is, when the stopper 141 moves away from the imaging body 210, the connecting rod 137 can be moved, so that the pull rod 136 overcomes the elastic force of the elastic part 135 and rotates, thereby driving the tensioning part 134 to rotate from the first position to the second position.

[0084] Please refer to Figure 3 to Figure 4 In one embodiment, avoidance holes 142 are respectively provided on both sides of the support portion 140. The docking structure 130 further includes a rotating shaft 138, which is passed through the mounting seat 132, and both ends of the rotating shaft 138 extend out of the avoidance holes 142 on both sides of the support portion 140. Two pull rods 136 are respectively connected to both ends of the rotating shaft 138, and are rotatably connected to the mounting seat 132 through the rotating shaft 138.

[0085] Please refer to Figure 1An embodiment of the present application provides a medical imaging device, comprising: an imaging device 200 and a medical bed 100 of any one of the above embodiments, wherein the imaging device 200 comprises an imaging body 210 and a receiving structure 220 disposed on the imaging body 210. The receiving structure 220 comprises: a docking base 221, an imaging side connector 222 and a limiting portion 223, wherein the docking base 221 is disposed on the imaging body 210 and is located on one side of the imaging body 210 along the first direction X, and the imaging side connector 222 and the limiting portion 223 are respectively disposed on the docking base 221.

[0086] Please refer to Figure 2 In one embodiment, the side of the limiting portion 223 away from the imaging subject 210 has an inclined surface 2231 inclined to the first direction X, and the inclined surface 2231 is inclined in a direction from the first position to the second position from the end of the inclined surface 2231 away from the imaging subject 210 to the end of the inclined surface 2231 close to the imaging subject 210. The inclined surface 2231 is used to abut against the tensioning portion 134 to guide the tensioning portion 134 to switch from the first position to the second position when moving along the inclined surface 2231.

[0087] Since the slope 2231 is inclined from one end of the slope 2231 away from the imaging subject 210 to the end of the slope 2231 close to the imaging subject 210, when the tensioning portion 134 abuts against the slope 2231 and moves in the direction close to the imaging subject 210, it can move from the first position to the second position along the slope 2231 under the guidance of the slope 2231.

[0088] Please refer to Figure 2 In one embodiment, the receiving structure 220 includes a guide groove 2211 disposed on the docking base 221. The guide groove 2211 includes a fine guide section 2211a and a coarse guide section 2211b that are connected. The coarse guide section 2211b is disposed at the entrance of the fine guide section 2211a. The groove width of the coarse guide section 2211b gradually increases along the direction in which the coarse guide section 2211b moves away from the fine guide section 2211a, thereby facilitating the guide portion 160 to enter the guide groove 2211 from the coarse guide section 2211b. Since the groove width of the fine guide section 2211a is uniform, when the guide portion 160 moves from the coarse guide section 2211b to the fine guide section 2211a, it can accurately move along the first direction X under the guidance of the fine guide section 2211a.

[0089] Please refer to Figures 3 to 7 The guide portion 160 is provided with a guide pulley 161 , and the guide pulley 161 can slide along the guide groove 2211 , so as to facilitate the movement of the guide portion 160 along the guide groove 2211 .

[0090] Preferably, guide pulleys 161 are respectively provided on both sides of the guide portion 160 along the second direction Y. The spacing between the outer end surfaces of the guide pulleys 161 on both sides of the guide portion 160 along the second direction Y is adapted to the groove width of the precision guide segment 2211a, so that when the guide pulleys 161 on both sides of the guide portion 160 along the second direction Y cooperate with the precision guide segment 2211a, the movement of the guide portion 160 along the first direction X can be accurately limited.

[0091] In one embodiment, the medical imaging device includes a prompting device. The electric drive assembly drives the mounting seat 132 and the support body 120 to move relative to each other along the first direction X, so that during the process that the support body 120 drives the bedside connector 131 to dock with the imaging side connector 222, the prompting device is used to issue a first prompting message to indicate that the bedside connector 131 and the imaging side connector 222 are docking.

[0092] In the process of driving the support body 120 to move away from the imaging body 210 by the driving mechanism equipped by the support body 120 itself to separate the bed side connector 131 from the imaging side connector 222, the prompt device is used to issue a second prompt information to indicate that the bed side connector 131 and the imaging side connector 222 are in docking.

[0093] The prompt device may include an acoustic prompt module (such as a buzzer), and the acoustic prompt module is used to issue an acoustic prompt message. The prompt device may include a prompt light, and the prompt light is used to issue a light prompt message. The prompt device may include a display screen, and the display screen is used to display a pattern prompt message or a text prompt message. The first prompt message may be an acoustic prompt message, a light prompt message, a pattern prompt message or a text prompt message. The second prompt message may be an acoustic prompt message, a light prompt message, a pattern prompt message or a text prompt message.

[0094] An embodiment of the present application further provides a method for docking a medical bed 100 with an imaging device 200, comprising the following steps:

[0095] S1: driving the supporting body 120 of the medical bed 100 to move toward the imaging device 200 so that the limiting portion 223 abuts against the tensioning portion 134, and the tensioning portion 134 changes from the first position to the second position.

[0096] S2: The supporting body 120 of the medical bed 100 is driven to continue to move, the tensioning portion 134 passes over the limiting portion 223 and returns to the first position from the second position under the action of the elastic portion 135 , and the tensioning portion 134 is hooked with the limiting portion 223 .

[0097] S3: driving the mounting seat 132 through the electric driving assembly to move the supporting body 120 to dock with the imaging device 200 .

[0098] In the docking method of the medical bed 100 and the imaging device 200, the medical bed 100 is moved as a whole along the first direction X close to the imaging device 200, so that the tensioning part 134 at the first position relative to the mounting seat 132 is moved along the first direction X close to the limiting part 223 until the tensioning part 134 abuts against the side of the limiting part 223 away from the imaging body 210. When the medical bed 100 is continuously moved as a whole along the first direction X close to the imaging device 200, the abutting force of the limiting part 223 on the tensioning part 134 can enable the tensioning part 134 to overcome the elastic force of the elastic part 135, so that the tensioning part 134 switches from the first position to the second position. The medical bed 100 is then moved along the first direction X close to the imaging device 200, and the tensioning portion 134 in the second position can be moved to the side of the limiting portion 223 close to the imaging subject 210, that is, the tensioning portion 134 moves from the side of the limiting portion 223 away from the imaging subject 210 to the side of the limiting portion 223 close to the imaging subject 210, so that the tensioning portion 134 is restored from the second position to the first position (at this time, the medical bed 100 is in the Figure 5 As the tensioning portion 134 is located on the side of the limiting portion 223 close to the imaging subject 210 and is in the first position, the limiting portion 223 can prevent the tensioning portion 134 from moving in the first direction X away from the imaging subject 210, thereby preventing the mounting seat 132 from moving in the first direction X away from the imaging subject 210. The position of the mounting seat 132 at this time is defined as the reference position. As the mounting seat 132 cannot move in the direction away from the imaging subject 210 when in the reference position, the mounting seat 132 and the support body 120 can be driven by the electric drive assembly to move relative to each other in the first direction X, so that the support body 120 moves in the direction close to the imaging subject 210, and the support body 120 drives the bedside connector 131 to move in the direction close to the imaging side connector 222, so that the bedside connector 131 and the imaging side connector 222 are connected. Among them, since the tensioning part 134 is located on the side of the limiting part 223 close to the imaging subject 210 and is in the first position, it can be blocked by the limiting part 223, thereby preventing the medical bed 100 from moving away from the imaging subject 210, that is, preventing the bedside connector 131 from moving in the direction of separating from the imaging side connector 222, so that the bedside connector 131 and the imaging side connector 222 can be reliably docked. The above docking method realizes the electric docking of the medical bed and the imaging device through the electric drive of the electric drive component, which reduces the bulkiness and improves the operating comfort compared with the hydraulic component.

[0099] In one embodiment, step S3 includes: driving the mounting seat 132 in a direction away from the imaging device 200 through an electric drive component, and the hooking state between the tensioning portion 134 and the limiting portion 223 can prevent the mounting seat 132 from moving in a direction away from the imaging device 200, so that the driving force exerted on the mounting seat 132 reacts to the supporting body 120, so that the supporting body 120 moves toward the imaging device 200 to complete the docking.

[0100] In one embodiment, when the supporting body 120 moves along the first direction toward the imaging device 200 , the guiding portion 160 moves along the guiding groove 2211 for guidance.

[0101] In one embodiment, when the tensioning portion 134 moves to the side of the limiting portion 223 close to the imaging body 210 and returns to the first position, that is, when the tensioning portion 134 is hooked with the limiting portion 223, the signal generator 150 generates an induction signal, and the induction signal triggers the electric drive component to automatically drive the mounting base 132, so that the support body 120 moves and docks with the imaging device 200.

[0102] In one embodiment, step S3 includes: driving the supporting body 120 of the medical bed 100 to move along the first direction X toward the imaging device 200 until the front end of the mounting seat 132 abuts against the stop portion 224 of the imaging device 200 .

[0103] When the mounting seat 132 abuts against the side of the stopper 224 of the imaging device 200 away from the imaging body 210 along the first direction X, the tensioning portion 134 moves to the side of the limiter 223 close to the imaging body 210, so that the tensioning portion 134 returns from the second position to the first position. That is, the moment when the mounting seat 132 reaches the reference position can be determined by the stopper 224, so as to facilitate the start of the electric drive assembly to drive the mounting seat 132 and the supporting body 120 to move relative to each other along the first direction X, so as to enable the supporting body 120 to drive the bed-side connector 131 to dock with the imaging-side connector 222.

[0104] An embodiment of the present application further provides a method for separating a medical bed 100 from an imaging device 200, comprising the following steps:

[0105] S10: Drive the supporting body 120 of the medical bed 100 to move away from the imaging device 200, so that the stopper 141 pushes the tensioning assembly, so that the pull rod 136 rotates to drive the tensioning part 134 to change from the first position to the second position, and the limiting part 223 releases the tensioning part 134.

[0106] When the bed-side connector 131 and the imaging-side connector 222 are connected, the limiting portion 223 blocks the tensioning portion 134 from moving away from the imaging subject 210 along the first direction X, thereby blocking the mounting seat 132 from moving away from the imaging subject 210 along the first direction X. Therefore, in the initial stage of the support body 120 moving away from the imaging subject 210, the mounting seat 132 does not move, and the support body 120 and the stopper 141 move relative to the mounting seat 132 at the same time, so that the stopper 141 pushes the pull rod 136 to rotate, and the pull rod 136 drives the tensioning portion 134 to move, and then the tensioning portion 134 overcomes the elastic force of the elastic portion 135 and switches from the first position to the second position.

[0107] S20: Drive the support body 120 of the medical bed 100 to continue to move away so that the bed side connector 131 on the support body 120 is separated from the imaging side connector 222 of the imaging device 200, and the mounting seat 132 and the tensioning part 134 move together with the support body 120.

[0108] When the tensioning portion 134 is switched to the second position, it is not blocked by the limiting portion 223, so that the tensioning portion 134 and the mounting seat 132 can move in the direction away from the imaging subject 210, and then when the supporting body 120 continues to move away from the imaging subject 210, the mounting seat 132 moves synchronously with it, the bed side connector 131 and the imaging side connector 222 are separated, and the medical bed 100 is separated from the imaging device 200.

[0109] However, sometimes due to unexpected circumstances and other reasons, the medical bed loses power, and the electric drive mechanism equipped in the support body 120 loses power, which results in the inability to drive the support body 120 to drive the stopper 141 to switch the tensioning part 134 to the second position through the electric driving force in step S10, so that the limiter 223 will keep blocking the tensioning part 134 in the first position, resulting in the support body 120 being unable to move in the direction away from the imaging body 210, and thus unable to achieve the separation of the bed side connector 131 and the imaging side connector 222. To this end, an embodiment of the present application provides a docking and disengagement structure of a mobile medical bed, which can achieve mechanical disengagement of the medical bed and the imaging device.

[0110] Please combine Figure 2 , Figure 8 and Fig. 9, a docking and disengagement structure of a mobile medical bed provided in an embodiment of the present application. The docking and disengagement structure of the mobile medical bed includes: a docking base 221, a sliding part 310, a first elastic member 311 and an operating part 320. The docking base 221 is arranged on the imaging body 210 and is located on one side of the imaging body 210 along the first direction X. The first direction X is along the axial direction of the imaging channel of the imaging body 210. The sliding part 310 is slidably connected with the docking base 221 along the second direction Y. A limiting part 223 is arranged on the sliding part 310, and the sliding part 310 has a blocking position and a release position that are switched along the second direction Y relative to the docking base 221. In the blocking position, the limiting part 223 can block the tensioning part 134 of the medical bed 100 from moving away from the imaging body 210 along the first direction X. In the release position, the limiting part 223 releases the blocking of the tensioning part 134. The docking base 221 and the sliding part 310 are respectively connected to the first elastic member 311, and the first elastic member 311 is used to drive the sliding part 310 to switch from the release position to the blocking position. The operating part 320 is rotatably connected to the docking base 221 around the axis of the first direction X. When the operating part 320 rotates relative to the docking base 221, it can push the sliding part 310 to switch from the blocking position to the release position.

[0111] In the docking and disengagement structure of the mobile medical bed, when the bed-side connector 131 needs to be separated from the imaging-side connector 222, if the driving mechanism of the supporting body 120 of the medical bed 100 loses power, the operating part 320 can be rotated manually. When the operating part 320 rotates relative to the docking base 221, it can push the sliding part 310 to overcome the elastic force of the first elastic member 311, so that the sliding part 310 switches from the blocking position to the releasing position along the second direction Y. In this process, the limiting part 223 on the sliding part 310 moves synchronously along the second direction Y. Since the limiting part 223 can block the tensioning part 134 of the medical bed 100 from moving away from the imaging subject 210 along the first direction X when the sliding part 310 is in the blocking position, when the limiting part 223 switches to the releasing position along the second direction Y synchronously with the sliding part 310, the limiting part 223 and the tensioning part 134 can be staggered along the second direction Y, so that the blocking of the tensioning part 134 along the first direction X by the limiting part 223 can be released, that is, the restriction of the support body 120 of the medical bed 100 from moving away from the imaging subject 210 along the first direction X is released. In this way, the support body 120 of the medical bed 100 can be moved away from the imaging subject 210 along the first direction X, so that the support body 120 can drive the bed-side connector 131 to separate from the imaging-side connector 222. In this way, the driving mechanism of the supporting body 120 of the medical bed 100 loses power, and the bed-side connector 131 cannot be separated from the imaging-side connector 222, that is, the medical bed 100 cannot be separated from the imaging device 200. The bed-side connector 131 and the imaging-side connector 222 can be separated by the docking and disengagement structure of the mobile medical bed to prevent the medical bed 100 and the imaging device 200 from being locked, thereby meeting the safety requirements of the medical industry standards.

[0112] When the bedside connector 131 and the imaging side connector 222 are separated, the operating part 320 can be released, and the elastic restoring force of the first elastic member 311 can drive the sliding part 310 to switch from the release position to the blocking position. In this way, when the bedside connector 131 of the medical bed 100 is docked with the imaging side connector 222 of the imaging device 200 again, the limiting part 223 can be used to prevent the tensioning part 134 from moving away from the imaging body 210 along the first direction X.

[0113] The first elastic member 311 may be a gas spring, a coil spring, an elastic block, or the like.

[0114] like Figure 8 As shown, in one embodiment, the operating part 320 includes an operating rod 323 and a force applying part 322. One end of the operating rod 323 away from the docking base 221 is connected to the force applying part 322. The force applying part 322 can be a foot pedal, so that the operating part 320 can be rotated by stepping on the foot pedal, which is convenient for operation.

[0115] Please combine Figure 2 , Figure 8 and Fig. 9 In one embodiment, the docking and disengagement structure of the mobile medical bed includes an ejector 330 and a second elastic member 331. The ejector 330 is slidably connected to the docking base 221 along the first direction X, and the ejector 330 and the docking base 221 are respectively connected to the second elastic member 331. The ejector 330 has an ejection position and a return position that are switched along the first direction X. In the return position, the ejector 330 allows the support body 120 of the medical bed 100 to drive the bed-side connector 131 to complete the docking with the imaging-side connector 222. In the ejection position, the ejector 330 pushes the support body 120 until the bed-side connector 131 is separated from the imaging-side connector 222. The second elastic member 331 is used to drive the ejector 330 to switch from the ejection position to the return position.

[0116] The sliding part 310 is provided with a linkage part 340. After the sliding part 310 is switched to the release position, the operating part 320 can push the sliding part 310 to move along the second direction Y when rotating relative to the docking base 221, so that the sliding part 310 drives the linkage part 340, and the linkage part 340 pushes the ejection part 330 to switch from the return position to the ejection position.

[0117] When the bedside connector 131 and the imaging side connector 222 are connected, the ejection part 330 is in the return position. When the bedside connector 131 needs to be separated from the imaging side connector 222, if the driving mechanism of the support body 120 of the medical bed 100 loses power, the operating part 320 can be manually rotated in the previous embodiment to switch the sliding part 310 to the release position. After the sliding part 310 switches to the release position, the operating part 320 continues to be rotated in the same direction, and the sliding part 310 continues to move away from the blocking position along the second direction Y, and at the same time, the linkage part 340 on the sliding part 310 moves synchronously. During the movement of the linkage part 340, the ejection part 330 is pushed to overcome the elastic force of the second elastic member 331, so that the ejection part 330 switches from the return position to the ejection position. In the process of switching from the return position to the ejection position, the ejection part 330 can push the support body 120 to drive the bedside connector 131 to separate from the imaging side connector 222. This makes it very convenient to detach the bed-side connector 131 from the imaging-side connector 222 .

[0118] When the bedside connector 131 and the imaging side connector 222 are completely separated, after the operating part 320 is released, the elastic restoring force of the second elastic member 331 can drive the ejection part 330 to switch from the ejection position to the return position. In this way, when the bedside connector 131 of the medical bed 100 is docked with the imaging side connector 222 of the imaging device 200 again, the ejection part 330 can make way for the support body 120, so that the support body 120 drives the bedside connector 131 to move to the position where the docking with the imaging side connector 222 is completed.

[0119] The second elastic member 331 may be a gas spring, a coil spring, an elastic block, or the like.

[0120] refer to Figure 2 In one embodiment, the docking base 221 has a receiving cavity, the sliding portion 310 is located in the receiving cavity, and the end of the docking base 221 facing away from the imaging body 210 has an opening for the docking structure 130 to enter.

[0121] Please combine Figure 8 and Fig. 9 In one embodiment, the linkage part 340 is located on a side of the ejection part 330 close to the imaging subject 210, and the linkage part 340 has a linkage surface 341 facing the ejection part 330, which is used to abut against the ejection part 330. The linkage surface 341 is inclined to the first direction X and the second direction Y, and from the end of the linkage surface 341 close to the medical bed 100 to the end away from the medical bed 100, the linkage surface 341 is inclined in the direction from the blocking position to the release position, so that the linkage part 340 can push the ejection part 330 to switch from the return position to the ejection position through the linkage surface 341.

[0122] After the sliding part 310 switches to the release position, it continues to move away from the blocking position along the second direction Y and drives the linkage part 340 to move synchronously. The linkage surface 341 moves synchronously in the direction away from the blocking position along the second direction Y. Since the linkage surface 341 is inclined in the direction from the blocking position to the release position from the end of the linkage surface 341 close to the medical bed 100 to the end away from the medical bed 100, the linkage surface 341 is inclined. Therefore, in the process of the linkage surface 341 moving synchronously in the second direction Y in the direction away from the blocking position, the ejection part 330 can be pushed to move along the first direction X, so that the ejection part 330 switches from the return position to the ejection position.

[0123] When the bedside connector 131 and the imaging side connector 222 are separated, after the operating part 320 is released, the elastic restoring force of the first elastic member 311 drives the sliding part 310 to switch from the release position to the blocking position, and the linkage part 340 moves synchronously with the sliding part 310 .

[0124] Please refer to Figure 8 and Fig. 9 In one embodiment, a roller 334 is provided at one end of the ejection part 330 away from the medical bed 100, and the roller 334 rolls with the linkage surface 341. Through the rolling cooperation between the linkage surface 341 and the roller 334, the sliding friction in the process of the linkage surface 341 pushing the ejection part 330 can be converted into rolling friction, thereby reducing the resistance when pushing the ejection part 330, and facilitating the ejection part 330 to be pushed to the ejection position.

[0125] like Figure 8 and Fig. 9As shown, in one embodiment, an ejection track 332 is provided on the docking base 221, and the ejection portion 330 and the ejection track 332 move and cooperate along the first direction X, so as to accurately guide the movement direction of the ejection portion 330, and facilitate accurate switching between the ejection position and the return position. The end of the ejection portion 330 away from the medical bed 100 extends out of the ejection track 332 and cooperates with the linkage portion 340.

[0126] like Figure 8 and Fig. 9 As shown, in one embodiment, the end of the ejection part 330 away from the medical bed 100 has a protrusion 333. The second elastic member 331 is sleeved on the ejection part 330 and is located between the protrusion 333 and the ejection track 332. One end of the second elastic member 331 abuts against the protrusion 333, and the other end abuts against the ejection track 332. In this way, the second elastic member 331 can provide elastic force between the ejection part 330 and the docking base 221 through the ejection track 332.

[0127] like Figure 8 and Fig. 9 As shown, in one embodiment, the end of the ejection portion 330 away from the medical bed 100 has a protrusion 333, and the roller 334 can be installed on the protrusion 333, that is, the protrusion 333 is used as a mounting bracket for the roller 334. Alternatively, an additional mounting bracket can be added to the protrusion for mounting the roller.

[0128] like Figure 8 As shown, in one embodiment, the sliding part 310 is slidably connected to the docking base 221 along the second direction Y through the slide rail 312. A slider is fixed to the side of the sliding part 310 facing the slide rail 312, and the slider is slidably connected to the slide rail 312 along the second direction Y.

[0129] like Figure 8 As shown, in one embodiment, the sliding part 310 is provided with an avoidance groove 315, and the end of the ejection track 332 away from the medical bed 100 has a connecting part 3321. The connecting part 3321 passes through the avoidance groove 315 and is fixedly connected to the docking base 221. And the connecting part 3321 is movably matched with the avoidance groove 315 along the second direction Y. In this way, when the sliding part 310 moves along the second direction Y, the connecting part 3321 moves relatively in the avoidance groove 315, so that the ejection track 332 can be connected to the docking base 221, and the sliding part 310 is allowed to move along the second direction Y relative to the docking base 221 and the ejection track 332.

[0130] In one embodiment, the sliding portion 310 includes a slide plate, and the limiting portion 223 and the linkage portion 340 are disposed on the slide plate.

[0131] Please refer to Figure 8In one embodiment, one of the operating part 320 and the sliding part 310 is provided with a sliding shaft 321 and the other is provided with a sliding groove 361. The sliding shaft 321 and the sliding groove 361 are slidably matched. In this way, when the operating part 320 rotates relative to the docking base 221, the sliding part 310 can be pushed to move along the second direction Y through the sliding match between the sliding shaft 321 and the sliding groove 361. Figure 8 In the illustrated embodiment, the sliding shaft 321 is disposed on the operating portion 320 . The sliding groove 361 is disposed on the sliding portion 310 .

[0132] Specifically, the operating portion 320 includes an operating rod 323 , and the sliding shaft 321 is disposed at one end of the operating rod 323 away from the force applying portion 322 .

[0133] In one embodiment, the sliding part 310 includes a push rod 360, and when the operating part 320 rotates relative to the docking base 221, the push rod 360 can be pushed, so that the push rod 360 drives the sliding part 310 to switch from the blocking position to the releasing position. Specifically, the operating part 320 and the push rod 360 on the sliding part 310 are provided with a sliding shaft 321 on one side and a sliding groove 361 on the other side. Figure 8 In the illustrated embodiment, the slide slot 361 is disposed on the push rod 360 .

[0134] In one embodiment, the operating portion 320 is disposed on one side of the docking base 221 along the second direction Y for easy operation.

[0135] refer to Figure 8 In one embodiment, a fixing seat 350 is provided on the docking base 221 , and the operating portion 320 is rotatably connected to the fixing seat 350 around an axis of the first direction X, thereby being rotatably connected to the docking base 221 through the fixing seat 350 .

When the operating portion 320 rotates, it can push the end of the push rod 360 away from the linkage portion 340, thereby pushing the push rod 360 to move along the second direction Y.

[0137] Specifically, one end of the push rod 360 away from the linkage portion 340 and the operating portion 320 is provided with a sliding shaft 321 , and the other end is provided with a sliding groove 361 .

[0138] In one embodiment, a connection seat 314 is disposed on the docking base 221 , and the connection seat 314 is located on one side of the linkage portion 340 along the second direction Y. One end of the second elastic member 311 is connected to the connection seat 314 , and the other end is connected to the linkage portion 340 .
