Therefore, the specification and drawings are only for the purpose of clearly describing a certain embodiment and do not mean that the composition and / or sequence are necessary.

[0035] The serial numbers of the components in this document, such as "first", "second", etc., are only used to distinguish the objects described and do not have any order or technical meaning. The "connection" and "coupling" mentioned in this application, unless otherwise specified, include direct and indirect connections (couplings).

[0036] The present application provides a mobile device, which can be a medical mobile device, such as a mobile DR device, which is mainly used to perform X-ray photography on patients and analyze the patient's condition through photographed images. The mobile device can also be other medical devices, such as an ultrasound device with a probe.

[0037] refer to Figure 1-8The mobile device includes a column 1000 for the mobile device, the column 1000 includes a base 1100, a fixing unit 1200, an installation unit 1300, a first transmission member 1400, a second transmission member 1500, a transmission unit 1600 and an anti-falling unit 1700, the fixing unit 1200 is fixedly arranged on the base 1100, the installation unit 1300 can move relative to the fixing unit 1200 in a direction close to or away from the base 1100, the first transmission member 1400 is arranged on the fixing unit 1200, the second transmission member 1500 is arranged on the installation unit 1300, the transmission unit 1600 is arranged on the fixing unit 1200 and the installation unit The transmission unit 1600 has a first side and a second side that are relatively arranged. The first side of the transmission unit 1600 is transmission-connected to the first transmission member 1400, and the second side of the transmission unit 1600 is transmission-connected to the second transmission member 1500, so as to synchronously drive the transmission unit 1600 to move in the same direction relative to the fixing unit 1200 when the mounting unit 1300 moves in a direction close to or away from the base 1100. The output end of the anti-fall unit 1700 is connected to the transmission unit 1600, so as to provide a constant pulling force away from the base 1100 to the transmission unit 1600, so as to prevent the transmission unit 1600 and the mounting unit 1300 from falling.

[0038] The base 1100 and the fixing unit 1200 cooperate to provide support for the entire device. The mounting unit 1300 can be installed with the head assembly, which is the core component of the digital direct imaging system. It is based on the X-ray television system and uses computer digital processing to make the analog video signal directly enter the computer for storage, analysis and preservation after sampling and analog / digital conversion (A / D). The saved digital image has the advantages of high resolution, good sharpness, clear details, small radiation dose, large exposure tolerance, and various image post-processing according to clinical needs. It can also realize the film-free radiology department, and the networking between departments and hospitals is convenient for teaching and consultation. It generally includes a tube, a beam limiter, a handle and a display screen.

[0039] The mobile device can be moved to different parts according to needs. According to the usage habits, the column 1000 is set vertically. During medical examination, the height of the bull head assembly is adjusted by the column 1000 according to the height of the patient and the height of the examination part. The mounting unit 1300 includes a telescopic sleeve, and the bull head assembly is installed on the mounting unit 1300 through the telescopic sleeve. The distance between the bull head assembly and the mounting unit 1300 can be adjusted by the telescopic sleeve to adapt to the inspection work of different parts. The telescopic sleeve is arranged roughly in the horizontal direction, and there may also be a certain angle between the telescopic sleeve and the horizontal.

[0040] When an upward or downward force is applied to the installation unit 1300 manually or electrically, the transmission unit 1600, the first transmission member 1400 and the second transmission member 1500 cooperate with each other to enable the transmission unit 1600 to move in the same direction, that is, when the installation unit 1300 is forced to move downward, the transmission unit 1600 moves downward synchronously, and when the installation unit 1300 is forced to move upward, the transmission unit 1600 moves upward synchronously. The movement stroke of the transmission unit 1600 and the installation unit 1300 plus the length of the fixing unit 1200 can meet the different height usage requirements of the column 1000. The columns 1000 of different heights can also be designed according to the dimensions of the transmission unit 1600 and the installation unit 1300. At the same time, the transmission unit 1600 and the installation unit 1300 can be folded and stored so that the height of the entire column 1000 is the length of the fixing unit 1200, thereby reducing the height of the entire equipment, reducing the occupied volume, avoiding blocking the operator's line of sight during movement, and improving safety.

[0041] The transmission unit 1600 includes at least one transmission assembly 1610, which is arranged in sequence from the first side to the second side. Two adjacent transmission assemblies 1610 are in transmission connection. The transmission assembly 1610 located on the first side is in transmission connection with the first transmission member 1400, and the transmission assembly 1610 located on the second side is in transmission connection with the second transmission member 1500. When a force is applied to the installation unit 1300 to drive its movement, the transmission of force by the multiple transmission assemblies 1610 drives the multiple transmission assemblies 1610 to move, so that they can all generate a certain movement stroke relative to the fixed unit 1200. The movement stroke of the installation unit 1300 relative to the fixed unit 1200 is the maximum height that the entire column 1000 can adjust. When stored, the height of the entire column 1000 shrinks to the length of the fixed unit 1200.

[0042] refer to Figure 2 and 3 The transmission component 1610 is provided with a three-stage transmission. The transmission component 1610 includes a transmission seat 1611 and a third transmission member 1612. The third transmission member 1612 is arranged on the transmission seat 1611. The two sides of the third transmission member 1612 are respectively connected to the first transmission member 1400 and the second transmission member 1500.

[0043] The first transmission member 1400 and the second transmission member 1500 are both transmission racks, and the third transmission member 1612 is a transmission gear, which is rotatably disposed on the transmission seat 1611, and the two sides of the third transmission member 1612 are respectively meshed and connected with the first transmission member 1400 and the second transmission member 1500.

[0044] The first transmission member 1400 and the second transmission member 1500 are both transmission racks, and the third transmission member 1612 is a transmission gear. The transmission racks are extended on the mounting unit 1300 and the fixing unit 1200, respectively, and are parallel to the length direction (vertical direction) of the fixing unit 1200 or the mounting unit 1300. There are multiple transmission gears, and the multiple transmission gears are evenly arranged on the transmission seat 1611 along the extension direction parallel to the transmission rack.

[0045] In order to increase the stability of the entire transmission process and prevent the transmission unit 1600 from falling, the transmission gears are provided with at least three, preferably three, which can greatly improve the safety factor. Theoretically, only when three gears break teeth at the same time will the transmission unit 1600 and the installation unit 1300 suddenly fall, which can reduce the setting of other anti-fall structures and simplify the equipment structure.

[0046] In one embodiment, a plurality of transmission assemblies 1610 are provided, and the transmission assemblies 1610 include a transmission seat 1611 and a third transmission member 1612, wherein the third transmission member 1612 is arranged on the transmission seat 1611, and the third transmission members 1612 of two adjacent transmission assemblies 1610 are transmission connected, the transmission assembly 1610 located on the first side is transmission connected to the first transmission member 1400, and the transmission assembly 1610 located on the second side is transmission connected to the second transmission member 1500.

[0047] refer to Figure 5-8 The transmission assembly 1610 is provided with two, that is, a four-stage transmission, including a first transmission seat 16111, a second transmission seat 16112, a first transmission gear, a first transmission rack, a second transmission rack and a second transmission gear. The first transmission gear and the first transmission rack are arranged on the first transmission seat 16111 and on two opposite sides of the first transmission seat. Figure 6 and 7 As shown, based on the orientation shown in the figure, the first transmission gear is arranged on the right side of the first transmission seat 16111, the first transmission rack is arranged on the left side of the first transmission seat 16111, the second transmission gear and the second transmission rack are arranged on the second transmission seat 16112, the second transmission rack is arranged on the right side of the second transmission seat 16112, and the second transmission gear is arranged on the left side of the second transmission seat 16112. One side of the first transmission gear is transmission-connected with the first transmission member 1400 (transmission rack), and the other side is transmission-connected with the second transmission rack on the second transmission seat 16112, one side of the second transmission gear is transmission-connected with the first transmission rack on the first transmission seat 16111, and the other side is transmission-connected with the second transmission member 1500 (transmission rack). Among them, at least three first transmission gears and two transmission gears are evenly provided.

[0048] refer to Figure 4 The anti-fall unit 1700 includes a constant force output member 1710, a transmission wheel 1720 and a connecting member 1730. The constant force output member 1710 is arranged in the fixing unit 1200, the transmission wheel 1720 is arranged on the fixing unit 1200, one end of the connecting member 1730 is connected to the constant force output member 1710, and the other end is connected to the transmission unit 1600 after passing through the transmission wheel 1720. The constant force output member 1710 can output a constant pulling force, and the transmission wheel 1720 is used to transmit force and change the direction of force. The constant force output member 1710 always provides an upward constant pulling force to the transmission unit 1600 through the transmission wheel 1720. The constant pulling force can be a vertical upward constant pulling force or an inclined upward constant pulling force. The vertical upward constant pulling force (which may be the vertical upward component of the inclined upward constant pulling force) is approximately equal to the sum of the gravity of the installation unit 1300, the transmission unit 1600 and the bullhead assembly, so that the anti-fall unit 1700 can balance the gravity of the installation unit 1300, the transmission unit 1600 and the bullhead assembly. The doctor can move the bullhead assembly up and down by applying a small force by hand, which greatly facilitates the doctor's operation and avoids the installation unit 1300, the transmission unit 1600 and the bullhead assembly from falling and damaging the equipment during the operation.

[0049] In order to make the entire device have better stability, the transmission wheel 1720 is set at the top of the fixed unit 1200, and the constant force output member 1710 is set at the bottom of the fixed unit 1200. The weight of the constant force output member 1710 can also effectively balance part of the weight of the installation unit 1300, the transmission unit 1600 and the bullhead assembly.

[0050] In one embodiment, the constant force output member 1710 is a spring balancer or a pneumatic balancer. The spring balancer and the pneumatic balancer are mature products in the prior art, and have the advantages of small size and stable output of constant force. The spring balancer is a disc structure, including structures such as a torsion spring and a tower pulley, and the torsion of the torsion spring is used to achieve stable output of constant tension. The connecting member 1730 is a steel wire rope or other ropes or chains.

[0051] In one embodiment, the base 1100 is provided with walking wheels 2000 and a push-pull handle to facilitate the movement of the entire device.
