Furthermore, the steps or actions in the method description may be reordered or adjusted in a manner readily apparent to those skilled in the art. Therefore, the various sequences in the specification and drawings are provided solely for the purpose of clearly describing a particular embodiment and are not intended to be mandatory, unless otherwise specified.

[0051] The serial numbers assigned to components herein, such as "first," "second," etc., are used solely to distinguish the objects being described and do not convey any sequential or technical meaning. References to "connection" and "coupling" herein, unless otherwise specified, include both direct and indirect connections (couplings).

[0052] In response to the problem that the current detection bed of the X-ray imaging system is prone to pressing objects or maintenance personnel under the bed panel, the present application provides a detection bed of the X-ray imaging system, in which the driving mechanism of the detection bed of the X-ray imaging system can control the lifting and lowering of the bed panel. When the bed panel descends and encounters resistance from below, the transmission member connected to the driving mechanism moves relative to the lifting frame, so that the force transmission state between the transmission member and the lifting frame under the bed panel changes. The control module can stop the driving mechanism from controlling the descent of the lifting frame according to the change in the force transmission state, thereby improving the safety of the lifting bed. The contents of this application are illustrated below with reference to the accompanying drawings.

[0053] In one embodiment, please refer to Figure 1 and Figure 2 The detection bed of the X-ray imaging system includes a bed panel 1, a lifting frame 2, a transmission part 3, a driving mechanism 4, a force transmission detection part 5 and a control module, wherein the bed panel 1 is used for the patient to lie down, and the lifting frame 2 is used to drive the bed panel 1 to rise and fall.

[0054] The transmission member 3 is movably mounted on the lifting frame 2. The drive mechanism 4 is connected to the transmission member 3 and can transmit power to the transmission member 3. The transmission member 3 has a stopper 31, which is used to stop the lifting frame 2, allowing the drive mechanism 4 to apply force to the lifting frame 2 through the transmission member 3, thereby controlling the lifting of the lifting frame 2. The force transmission detector 5 is used to detect the force transmission between the stopper 31 and the lifting frame 2 and obtain the detection result.

[0055] When the lift frame 2 needs to be raised, the drive mechanism 4 applies a force to the transmission member 3, causing the stopper 31 of the transmission member 3 to stop the lift frame 2. The force of the drive mechanism 4 is then transmitted to the lift frame 2 via the stopper 31, driving the lift frame 2 to move upward and downward, thereby controlling the lift frame 2's ascent. When the lift frame 2 descends, the bed panel 1 descends under the action of gravity. The drive mechanism 4 applies a force to the transmission member 3, which is then transmitted to the lift frame 2 via the transmission member 3, preventing the lift frame 2 from descending too quickly and controlling the speed of the lift frame 2's descent, thereby controlling the bed panel 1's descent. If the bed panel 1 encounters resistance in its descent, the drive mechanism 4 can move the stopper 31 relative to the lift frame 2 or elastically deform the stopper 31, thereby changing the force transmission state between the stopper 31 and the lift frame 2.

[0056] The control module is connected to the force transmission detection member 5 and the driving mechanism 4 to obtain the detection result and control the driving mechanism 4 to stop controlling the lifting frame 2 to descend when the detection result does not meet the preset conditions.

[0057] When the driving mechanism 4 controls the lowering of the lifting frame 2 and the lowering of the bed panel 1 is blocked, the lowering of the lifting frame 2 will also be blocked, which will cause the stopper 31 to move relative to the lifting frame 2 or cause the stopper 31 to elastically deform. The force transmission detection member 5 detects a change in the force transmission state between the stopper 31 and the lifting frame 2. If the detection result of the force transmission detection member 5 does not meet the preset conditions, the control module can stop the driving mechanism 4 from controlling the lowering of the lifting frame 2 based on the detection result of the force transmission detection member 5, thereby preventing the driving mechanism 4 from further driving the lifting frame 2 to lower and causing damage to the operator or the pressed object. When the control module controls the driving mechanism 4 to stop controlling the lowering of the lifting frame 2, the operator cannot operate the driving mechanism 4 to lower the lifting frame 2, and the operator can be reminded to perform a safety check on the bed panel 1.

[0058] In one embodiment, the control switches of the examination bed of the X-ray imaging system include an up button and a down button. When the operator presses the up button, the drive mechanism 4 controls the lifting frame 2 to rise. When the operator releases the up button, the drive mechanism 4 controls the lifting frame 2 to stop rising. When the operator presses the down button, the drive mechanism 4 controls the lifting frame 2 to descend. When the operator releases the down button, the drive mechanism 4 stops controlling the lifting frame 2 to descend.

[0059] It should be noted that the "elastic deformation of the stopper 31" described in the above embodiment includes both increasing the elastic deformation of the stopper 31, decreasing the elastic deformation of the stopper 31, and starting elastic deformation of the stopper 31. It should be noted that the "driving mechanism 4 stops controlling the descent of the lifting frame 2" described in this application encompasses any feasible scenario, such as the driving mechanism 4 stopping controlling the descent of the lifting frame 2 and the lifting frame 2 neither ascending nor descending, or the driving mechanism 4 stopping controlling the descent of the lifting frame 2 while simultaneously controlling the descent of the lifting frame 2.

[0060] In one embodiment, the detection bed of the X-ray imaging system includes an anti-pressure prompting member (not shown in the figure), and the control module is connected to the force transmission detection member 5 and the anti-pressure prompting member, so as to control the anti-pressure prompting member to give an anti-pressure prompt when the detection result of the force transmission detection member 5 does not meet the preset conditions. The anti-pressure prompting member gives an anti-pressure prompt to remind the operator to pay attention, thereby improving the safety of the lifting bed. In one embodiment, the detection bed of the X-ray imaging system includes an anti-pressure prompting member, and the control module is connected to the driving mechanism 4. In this way, the control module can control both the driving mechanism 4 and the anti-pressure prompting member. When the bed panel 1 is blocked from descending, the control module controls the driving mechanism 4 to stop the driving mechanism 4 from controlling the descent of the lifting frame 2. At the same time, the control module can also give an anti-pressure prompt through the anti-pressure prompting member to remind the operator that the bed panel 1 is descending abnormally.

[0061] In this application, the change in the force transmission state between the stopper 31 and the lifting frame 2 includes various situations. For example, in one embodiment, the stopper 31 can transmit power when in contact with the lifting frame 2, but no longer transmits power when out of contact. Therefore, the change in the force transmission state is a change between a contact state and a non-contact state. In another embodiment, the stopper 31 is always in contact with the lifting frame 2, and the stopper 31 elastically deforms. Therefore, the change in the force transmission state is a change in the amount of elastic deformation of the stopper 31. For another example, in one embodiment, a change in the magnitude of the force between the stopper 31 and the lifting frame 2 indicates a change in the force transmission state.

[0062] Based on the change in the force transmission state, the force transmission detection member 5 can adopt any feasible method. For example, in one embodiment, the force transmission detection member 5 is a position detection member for detecting the change in the relative position of at least a portion of the stopper 31 and the lifting frame 2. Specifically, the position detection member can be a micro switch, a proximity switch, a distance sensor, etc. In one embodiment, the force transmission detection member 5 is a force detection member for detecting the magnitude of the force between the stopper 31 and the lifting frame 2. Specifically, the force detection member is a force sensor.

[0063] Based on the form of the force transmission detection member 5, the preset condition can also be set as needed. For example, the force transmission detection member 5 may be a microswitch. When the stopper 31 is no longer in contact with the lifting frame 2, the microswitch is triggered, indicating that the stopper 31 is out of contact with the lifting frame 2, and the descent of the bed panel 1 is blocked. In this case, the preset condition is that the stopper 31 and the lifting frame 2 cannot move relative to each other, which triggers the microswitch. For another example, the force transmission detection member 5 may be a force sensor. The preset condition is that the force between the stopper 31 and the lifting frame 2 is not less than a set value. When the force between the stopper 31 and the lifting frame 2 is less than the set value, it indicates that the stopper 31 and the lifting frame 2 are out of contact or have a large relative movement, and the descent of the bed panel 1 is blocked.

[0064] In one embodiment, the anti-pressure prompting member is an audible and visual prompting member, which gives an anti-pressure prompt by emitting a sound and / or emitting a warning light.

[0065] In one embodiment, please refer to Figure 1 and Figure 2 , the driving mechanism 4 is movably connected to the transmission member 3. Specifically, in one embodiment, please refer to Figure 1 and Figure 2 , the driving mechanism 4 is hinged to the transmission member 3. In some other embodiments, the driving mechanism 4 and the transmission member 3 can also be movably connected through multiple joints.

[0066] In some other embodiments, the drive mechanism 4 and the transmission member 3 may also be fixedly connected. For example, the drive mechanism 4 is a vertically arranged electric push rod or drive cylinder. The drive mechanism 4 includes a push rod, which extends upward to push the lifting frame 2 upward and retracts downward to control the lifting frame 2 to descend. The push rod always remains vertical during its movement. In this case, the push rod is fixed to the transmission member 3, and the transmission member 3 and the lifting frame 2 can be in a pushing cooperation. When the bed panel 1 is blocked from descending, the transmission member 3 and the lifting frame 2 separate vertically, and the stopper 31 is located at the top of the transmission member 3. Of course, in some other embodiments, when the drive mechanism 4 is a vertically arranged electric push rod or drive cylinder, the transmission member 3 can also be movably connected to the drive mechanism 4.

[0067] The control module can be in any feasible form. For example, in one embodiment, the control module is a processor. In another embodiment, the control module is a single-chip microcomputer. In one embodiment, the control module is a circuit board with a processor, and the circuit board is communicatively connected to the force transmission detection member 5 and is communicatively connected to the drive mechanism 4.

[0068] In one embodiment, please refer to Figure 1 and Figure 2 , the transmission member 3 is a swing member mounted on the lifting frame 2. Specifically, in one embodiment, please refer to Figure 1 The swinging member is a swing arm 30, with a stopper 31 at one end. The other end of the swing arm 30 is movably connected to the drive mechanism 4, and the middle portion of the swing arm 30 is hingedly connected to the lifting frame 2 via a pin. This simplifies the connection structure between the swing arm 30 and the drive mechanism 4. In some other embodiments, the transmission member 3 can also move a movable member mounted on the lifting frame 2, with the drive mechanism 4 movably connected to the movable member.

[0069] Further, in one embodiment, please refer to Figure 1 and Figure 2 The drive mechanism 4 is a telescopic drive mechanism. One end of the telescopic drive mechanism is hinged to one end of the swing arm 30. The telescopic drive mechanism controls the lifting frame 2 to rise by pushing the swing arm 30. The transmission structure of the telescopic drive mechanism is simple and easy to install. Compared with the method of pulling the lifting frame 2, the telescopic drive mechanism has a better load-bearing effect by pushing the lifting frame 2 to raise the lifting frame 2. Specifically, in one embodiment, please refer to Figure 1 and Figure 2 The telescopic driving mechanism is an electric push rod 40, which includes a driving motor and a screw-nut mechanism. The screw-nut mechanism converts the rotational motion of the driving motor into linear motion, and utilizes the forward and reverse rotation of the driving motor to complete the push rod action.

[0070] Regarding the lifting frame 2, in one embodiment, please refer to Figure 1 and Figure 2The lifting frame 2 includes a first scissor fork arm mechanism 21, a second scissor fork arm mechanism (not shown), and a connecting arm 22. The connecting arm 22 connects the first scissor fork arm mechanism 21 and the second scissor fork arm mechanism. The first scissor fork arm mechanism 21 includes a first swing arm 211, and the second scissor fork arm mechanism includes a second swing arm. The first swing arm 211 and the second swing arm move synchronously. The connecting arm 22 connects the first swing arm 211 and the second swing arm. The driving mechanism 4 drives the first and second scissor fork arm mechanisms 21 and 21 through the connecting arm 22. The transmission member 3 is mounted on the connecting arm 22, and the connecting arm 22 is configured to engage with the stop portion 31. The connecting arm 22 connects the first and second scissor fork arm mechanisms 21 and 21, and can simultaneously drive the first and second scissor fork arm mechanisms to move, thereby making the bed panel 1 more stable. In one embodiment, the first and second scissor fork arm mechanisms 21 and 21 are spaced apart in the width direction of the bed panel 1.

[0071] Specifically, in one embodiment, please refer to Figure 1 and Figure 2 The connecting arm 22 includes a stopper 221, and the force transmission detection component 5 includes a slot switch 51 installed on the stopper 221 and a sensor piece 52 installed on the swing arm 30. When a foreign object is pressed under the bed panel 1, the bed panel 1 cannot descend, but the electric push rod 40 can still descend. The electric push rod 40 pulls the swing arm 30 to swing. At this time, the sensor piece 52 installed on the swing arm 30 leaves the photosensitive hole of the slot switch 51, and the slot switch 51 recognizes the signal and transmits it to the control module. The control module cuts off the power supply of the electric push rod 40, and the electric push rod 40 stops descending.

[0072] In another embodiment, please refer to Figure 3 The slot switch 51 can also be changed to a micro switch 53 or a proximity switch. After the electric push rod 40 pulls the swing arm 30 to move relative to the block 221, the micro switch 53 or the proximity switch is triggered and sends a signal to the control module, which controls the electric push rod 40 to stop descending.

[0073] In some other embodiments, the transmission member 3 may also be directly mounted on the first swing arm 211 or the second swing arm. In some other embodiments, only one scissor-fork arm mechanism may also be provided.

[0074] In some other embodiments, the lifting frame 2 may also include guide posts and guide sleeves, the guide posts are connected to the bed panel 1, and the driving mechanism 4 drives the guide posts to move up and down to achieve the lifting of the bed panel 1.

[0075] In one embodiment, in order to reduce the pressure on the bed panel 1, the detection bed of the X-ray imaging system includes a gas spring, which is connected to the bed panel 1 or the lifting frame 2 and is used to support the bed panel 1. In this way, when a maintenance person or a pressed object is below the bed panel 1 to prevent the bed panel 1 from descending, the gas spring can provide a certain supporting force to reduce the force on the maintenance person or the pressed object. In one embodiment, one end of the gas spring is hinged to the lifting frame 2, and the other end is hinged to the base 6 of the detection bed of the X-ray imaging system. Specifically, in one embodiment, the number of gas springs is two or more, at least one gas spring is hinged to the first swing arm 211, and at least one gas spring is hinged to the second swing arm.

[0076] In one embodiment, to improve the safety of the X-ray imaging system's inspection bed, the X-ray imaging system's inspection bed further includes a height detection device for measuring the actual height of the bed panel. The actual height of the bed panel is defined as the height of the bed panel relative to a reference plane. The reference plane can be the ground or the mounting platform on which the lift bed is mounted.

[0077] The detection bed of the X-ray imaging system also includes a transmission data module for obtaining transmission data of the lifting frame and / or the driving mechanism. The control module is connected to the transmission data module so as to be able to calculate the calculated height of the bed panel based on the data of the transmission data module. The control module is connected to the height detection device and is used to control the driving mechanism to stop controlling the lifting frame to descend when the actual height of the bed panel exceeds the calculated height target value. The transmission data of the lifting frame and / or the driving mechanism can be of any feasible type, such as the lifting data of the lifting frame, the rotation data of the motor in the driving mechanism, the rotation data of the rotating transmission member in the lifting frame, the linear motion data of the linear motion transmission member in the lifting frame, etc. Correspondingly, the transmission data module can be an encoder or potentiometer that obtains rotation data, or a distance measuring sensor that obtains linear motion data.

[0078] It should be noted that when the transmission data module is used to obtain the transmission data of the lifting frame to detect whether the bed panel is blocked, at least part of the lifting frame can move asynchronously with the bed panel, for example, the lifting frame and the bed panel can be separated, or there is an elastic buffer between the lifting frame and the bed panel.

[0079] Specifically, in one embodiment, the transmission data module includes an encoder or potentiometer, which is used to obtain rotational transmission data of the lifting frame and / or the drive mechanism. In one embodiment, when the bed panel is stationary, the drive mechanism can drive the lifting frame to move, and the first swing arm or the second swing arm can swing. The encoder or potentiometer is used to obtain the swing angle of the first swing arm or the second swing arm. In one embodiment, the drive mechanism 4 includes a drive motor, and the encoder is used to obtain rotational data of the drive motor.

[0080] The height detection device can obtain the actual height data of the bed panel 1, and the transmission data module can obtain the transmission data of the lifting frame and / or drive mechanism. When the difference between the bed panel height calculated based on the transmission data and the actual height of the bed panel 1 exceeds a set value, indicating that the bed panel 1 is blocked or that maintenance personnel or objects are trapped under the bed panel 1, the control module controls the drive mechanism 4 to stop controlling the lifting frame 2 to descend. By comparing the actual bed panel height with the calculated height, the safety of the inspection bed in the X-ray imaging system can be further improved.

[0081] Specifically, in one embodiment, the height detection device is a height sensor. The height sensor can use any feasible sensor form, such as a wire sensor. In one embodiment, the inspection bed of the X-ray imaging system includes a base 6, and the lifting frame and height sensor are also mounted on the base 6. In some other embodiments, the height sensor can also be mounted on the bed panel.

[0082] In one embodiment, please refer to Figure 1 and Figure 2 , the working principle of the detection bed of the X-ray imaging system is as follows:

[0083] When the bed panel 1 needs to be raised, the operator presses the raising button, the driving mechanism 4 applies a force to the transmission member 3, the transmission member 3 is blocked by the lifting frame 2, and the force is transmitted to the lifting frame 2, causing the lifting frame 2 to rise.

[0084] To lower the bed panel 1, the operator presses the lower button, causing the drive mechanism 4 to apply force to the transmission member 3, which transmits this force to the lifting frame 2, causing the lifting frame 2 to descend at a preset rate. It should be noted that during the descent process, the bed panel 1 descends under gravity, and the drive mechanism 4 applies a certain amount of resistance to the bed panel 1 to prevent it from descending too quickly.

[0085] When a foreign object is pressed under the bed panel 1, the bed panel 1 cannot descend, and the lifting frame 2 also stops descending. The driving mechanism 4 drives the transmission member 3 to move relative to the lifting frame 2. The control module controls the driving mechanism 4 according to the detection result of the force transmission detection member 5, so that the driving mechanism 4 stops controlling the lifting frame 2 to descend.

[0086] In an embodiment of an X-ray imaging system, the X-ray imaging system includes a handpiece and a detection bed of the X-ray imaging system in any of the above embodiments, wherein the handpiece is configured to emit X-rays toward the detection bed of the X-ray imaging system.

[0087] The above specific examples are used to illustrate the present application, which is only used to help understand the present application and is not intended to limit the present application. For those skilled in the art of the present application, based on the concept of the present application, they can also make some simple deductions, modifications or substitutions.
