DETAILED DESCRIPTION

[0048] The present application is further described in detail below by specific embodiments in conjunction with the accompanying drawings. Wherein similar elements in different embodiments adopt associated similar element numbers. In the following embodiments, many detailed descriptions are intended to enable the present application to be better understood. However, those skilled in the art can easily recognize that some of the features can be omitted in different situations, or can be replaced by other elements, materials, and methods. In some cases, some operations related to the present application are not shown or described in the specification, in order to avoid the core part of the present application being overwhelmed by too much description, and for those skilled in the art, it is not necessary to describe these related operations in detail, and they can fully understand the related operations based on the description in the specification and the general technical knowledge in the art.

[0049] In addition, the features, operations or characteristics described in the specification can be combined in any appropriate manner to form various implementations, and the operation steps involved in each embodiment can also be replaced or adjusted in a sequence in a manner that is obvious to those skilled in the art. 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.

[0050] 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).

[0051] See also Figures 1 to 15 An embodiment of the utility model provides a support arm assembly 203, a support device 200 and a medical device 1000. The support device 200 includes the support arm assembly 203. The medical device 1000 includes a device host 100 and the support device 200. The device host 100 is carried on the support arm assembly 203 of the support device 200.

[0052] See also Figure 1 and Figure 2 The support arm assembly 203 provided in the embodiment of the utility model includes at least two swing arm members 10 and a rotating connection assembly 20 connected between two adjacent swing arm members 10. Through the rotating connection assembly 20, the two adjacent swing arm members 10 can rotate relative to each other.

[0053] In the embodiment of the present utility model, please refer to Figures 2 to 6 The rotating connection assembly 20 includes a rotating shaft 21 and a rotating base 22. The rotating shaft 21 is penetrated through the rotating base 22 so that the rotating base 22 can rotate around the axial direction of the rotating shaft 21; one of the two adjacent swing arm members 10 is connected to the rotating shaft 21, and the other of the two adjacent swing arm members 10 is connected to the rotating base 22.

[0054] When the rotating base 22 rotates around the axial direction of the rotating shaft 21, the rotating base 22 can be rotated relative to the rotating shaft 21. Since the rotating base 22 and the rotating shaft 21 are respectively connected to a swing arm 10, the rotating base 22 can drive the swing arm 10 connected thereto to rotate relative to the swing arm 10 connected to the rotating shaft 21, thereby realizing the relative rotation of two adjacent swing arm 10.

[0055] See also Figures 2 to 6 The rotating connection assembly 20 also includes a damping adjustment component 23, which is connected to one of the rotating shaft 21 and the rotating base 22, and abuts against the other of the rotating shaft 21 and the rotating base 22 to generate resistance to hinder the relative rotation of the rotating base 22 and the rotating shaft.

[0056] Since the damping adjustment component 23 is connected to one of the rotating shaft 21 and the rotating base 22, and abuts against the other of the rotating shaft 21 and the rotating base 22, when the rotating base 22 and the rotating shaft 21 rotate relative to each other, a friction force is generated between the rotating shaft 21 or the rotating base 22 abutting against the damping adjustment component 23 and the damping adjustment component 23, and the direction of action of the friction force is opposite to the direction of relative rotation between the rotating base 22 and the rotating shaft 21, that is, the resistance that hinders the relative rotation between the rotating base 22 and the rotating shaft. For example, the damping adjustment component 23 is connected to the rotating shaft 21 and abuts against the rotating base 22, and when the rotating base 22 and the rotating shaft 21 rotate relative to each other, a friction force is generated between the rotating base 22 and the damping adjustment component 23 to hinder the relative rotation between the rotating base 22 and the rotating shaft. For another example, the damping adjustment component 23 is connected to the rotating base 22 and abuts against the rotating shaft 21. When the rotating base 22 and the rotating shaft 21 rotate relative to each other, friction is generated between the rotating shaft 21 and the damping adjustment component 23 to hinder the relative rotation of the rotating base 22 and the rotating shaft.

[0057] In the embodiment of the utility model, the force of the damping adjustment component 23 abutting against the rotating shaft 21 or the rotating base 22 is adjustable. By adjusting the force of the damping adjustment component 23 abutting against the rotating shaft 21 or the rotating base 22, the magnitude of the friction between the damping adjustment component 23 and the rotating shaft 21 or between the damping adjustment component 23 and the rotating base 22 can be changed, that is, the magnitude of the resistance hindering the relative rotation of the rotating base 22 and the rotating shaft can be changed. For example, when the force of the damping adjustment component 23 abutting against the rotating shaft 21 or the rotating base 22 increases, the friction between the damping adjustment component 23 and the rotating shaft 21 or the rotating base 22 increases, that is, the resistance hindering the relative rotation of the rotating base 22 and the rotating shaft increases. For another example, when the force of the damping adjustment component 23 abutting against the rotating shaft 21 or the rotating base 22 decreases, the friction between the damping adjustment component 23 and the rotating shaft 21 or the rotating base 22 decreases, that is, the resistance hindering the relative rotation of the rotating base 22 and the rotating shaft decreases. In this way, the damping force of the swing arm 10 during rotation can be adjusted, increasing the adaptability to application scenarios or usage habits that require different damping forces. Specifically, the damping force of the swing arm 10 can be pre-adjusted during the assembly process before the device leaves the factory, or it can be adjusted in real time by the operator (medical staff) according to their own habits after leaving the factory, greatly improving the user experience of medical staff.

[0058] The damping adjustment component 23 can be configured to be connected to the rotating shaft 21 and abut against the rotating base 22, or can be configured to be connected to the rotating base 22 and abut against the rotating shaft 21. Below, the damping adjustment component 23 connected to the rotating shaft 21 and abutting against the rotating base 22 is taken as an example to further illustrate its structure.

[0059] See also Figure 4 and Figure 6The damping adjustment component 23 includes a ball plunger 231, a first mounting portion 2121 is provided on the rotating shaft 21, one end of the ball plunger 231 is threadedly connected to the first mounting portion 2121, and the other end of the ball plunger 231 elastically abuts against the rotating base 22. The length of the threaded connection between the ball plunger 231 and the first mounting portion 2121 can be changed to adjust the force of the abutment between the ball plunger 231 and the rotating base 22. The first mounting portion 2121 can be a threaded hole with threads provided on the hole wall, and the threads in the threaded hole match the threads of the ball plunger 231, so that the ball plunger 231 is threadedly connected to the first mounting portion 2121. When the length of the threaded connection between the ball plunger 231 and the first mounting portion 2121 is longer, the force of the abutment between the ball plunger 231 and the rotating base 22 is greater. When the length of the threaded connection between the ball plunger 231 and the first mounting portion 2121 is shorter, the force of the ball plunger 231 abutting against the rotating base 22 is smaller. By adjusting the length of the threaded connection between the ball plunger 231 and the first mounting portion 2121, the force of the abutment between the ball plunger 231 and the rotating base 22 can be adjusted, and the operation is simple and convenient.

[0060] In the embodiment of the utility model, the damping adjustment component 23 includes at least two ball plungers 231, and at least two first mounting portions 2121 are provided on the rotating shaft 21. The number of the first mounting portions 2121 on which the ball plungers 231 are installed can be changed to adjust the force of the damping adjustment component 23 abutting against the rotating base 22. That is, the magnitude of the resistance hindering the relative rotation of the rotating base 22 and the rotating shaft 21 can be adjusted by changing the number of ball plungers 231. When the number of ball plungers 231 increases, the resistance hindering the relative rotation of the rotating base 22 and the rotating shaft 21 can be increased, and when the number of ball plungers 231 decreases, the resistance hindering the relative rotation of the rotating base 22 and the rotating shaft 21 can be reduced.

[0061] For example, six first mounting portions 2121 may be provided on the rotating shaft 21 , and medical personnel may install six, five, four or three ball plungers 231 according to their own habits.

[0062] See also Figure 4 and Figure 6 The rotating shaft 21 includes a shaft body 211 and a first end cover 212. The first end cover 212 is connected to one end of the shaft body 211. The shaft body 211 is inserted into the rotating base 22. The first mounting portion 2121 is disposed on the first end cover 212. One end of the ball plunger 231 is threadedly connected to the first mounting portion 2121, and the other end of the ball plunger 231 elastically abuts against the end of the rotating base 22 close to the first end cover 212.

[0063] The rotating base 22 includes two oppositely disposed ends, which are defined as a first end 221 and a second end 222, respectively. The first end 221 is disposed close to the first end cover 212, and the second end 222 is disposed away from the first end cover 212. One end of the ball plunger 231 is threadedly connected to the first mounting portion 2121, and the other end of the ball plunger 231 elastically abuts against the first end 221 of the rotating base 22. A first gasket 241 is further disposed between the first end 221 of the rotating base 22 and the first end cover 212, and the other end of the ball plunger 231 elastically abuts against the first gasket 241, and then abuts against the first end 221 of the rotating base 22. The first gasket 241 is used to reduce the friction generated when the rotating base 22 and the rotating shaft 21 rotate relative to each other.

[0064] Among them, the first end cover 212 is fixed on the shaft body 211 by screws, the first gasket 241 has a thickness of 3.0mm, the spacing between the first end cover 212 and the first end 221 of the rotating base 22 is set to 3.2mm, and the first gasket 241 has a movable gap of 0.2mm above and below. At this time, 6 M5 ball head plungers 231 are screwed into the first end cover 212, so that the ball head plunger 231 presses the first gasket 241, and the spherical surface of the ball head plunger 231 protrudes about 0.8mm. When the ball head plunger 231 is screwed, the tighter the screwing, the smaller the length of the spherical protrusion, and the tighter the first gasket 241 is pressed. The damping size of the relative rotation of the rotating shaft and the rotating base 22 is adjusted by adjusting the number of screwed ball head plungers 231 and the degree of tightening, so as to find a force suitable for use. Of course, the connection method between the first end cover 212 and the shaft body 211 is not limited to screw fixed connection, and can also be fixedly connected by other methods, such as snap connection or bonding. In addition, the thickness of the first gasket 241 is not limited to 3.0 mm, and the distance between the first end cap 212 and the first end portion 221 of the rotating base 22 is not limited to 3.2 mm, and can be adjusted according to specific requirements. For example, the thickness of the first gasket 241 is 3.5 mm, and the distance between the first end cap 212 and the first end portion 221 of the rotating base 22 is set to 4 mm.

[0065] See also Figure 4 and Figure 6The rotating shaft 21 also includes a second end cap 213, which is connected to the other end of the shaft body 211 and is arranged opposite to the first end cap 212. The first end cap 212 and the second end cap 213 play a blocking role on the rotating base 22 to prevent the rotating base 22 and the shaft body 211 from being separated. The shaft body 211 and the second end cap 213 can be made by an integral molding process. When the rotating base 22 and the rotating shaft are assembled, the shaft body 211 is inserted into the rotating base 22 from the second end 222 of the rotating base 22 so that the rotating base 22 is sleeved on the periphery of the shaft body 211, and then the first end cap 212 is installed on the shaft body 211. A second gasket 242 is also provided between the second end 222 of the rotating base 22 and the second end cap 213, and the second gasket 242 is used to reduce the friction generated when the rotating base 22 and the rotating shaft 21 rotate relative to each other.

[0066] It should be noted that the relative positional relationship between the first end cap 212 and the second end cap 213 may be different in different rotating connection components 20 of the support arm component 203. For example, in one rotating connection component 20, the first end cap 212 is located above the second end cap 213, and in another rotating connection component 20, the first end cap 212 may be located below the second end cap 213. In addition, the positions where different rotating shaft components 21 are connected to the swing arm component 10 may be different. For example, one rotating shaft component 21 is connected to the swing arm component 10 through the first end cap 212 and the second end cap 213, and the other rotating shaft component 21 is connected to the swing arm component 10 through the second end cap 213. In addition, the structures of different rotating bases 22 may be different. For example, one rotating base 22 is a sleeve 22a, and the other rotating base 22 is a connecting plate 22b with a through hole. The sleeve 22a may be an independent component, and the connecting plate 22b may be an integrated structure with the swing arm component 10. In addition, the positions where the rotating base 22 is connected to the swing arm 10 can also be different. For example, the upper end of one rotating base 22 is connected to the swing arm 10, and the middle of another rotating base 22 is connected to the swing arm 10.

[0067] Among them, the limitations of directional words such as top, bottom, up, and down in this application are for ease of understanding. The description made when the medical device 1000 is in the use state is only used to reflect the relative position relationship between the structures. When the medical device 1000 is in other postures, the directional words in this application should be understood after switching to the use state.

[0068] Exemplarily, there are four swing arm members 10, which are connected end to end in sequence, namely, a first swing arm member 10a, a second swing arm member 10b, a third swing arm member 10c, and a fourth swing arm member 10d. There are three rotating connection components 20, namely, a first rotating connection component 20a, a second rotating connection component 20b, and a third rotating connection component 20c. The first rotating connection component 20a is connected between the first swing arm member 10a and the second swing arm member 10b, the second rotating connection component 20b is connected between the second swing arm member 10b and the third swing arm member 10c, and the third rotating connection component 20c is connected between the third swing arm member 10c and the fourth swing arm member 10d.

[0069] See also Figure 5 and Figure 6 The first end cover 212 of the first rotating connection assembly 20a is arranged above the second end cover 213 thereof, the second end cover 213 thereof is connected to the first swing arm 10a, and the rotating base 22 is arranged as a sleeve 22a. Figure 7 and Figure 8 The first end cover 212 of the second rotating connection assembly 20b is arranged below the second end cover 213 thereof, the first end cover 212 and the second end cover 213 thereof are both connected to the third swing arm 10c, and the rotating base 22 is arranged as a sleeve 22a. Fig. 9 and Fig.10 The first end cover 212 of the third rotating connection component 20c is arranged below its second end cover 213, and its second end cover 213 is connected to the fourth swing arm member 10d. The rotating base 22 is configured as a connecting plate 22b with a through hole, and the connecting plate 22b is connected to the third swing arm member 10c.

[0070] Among them, see Figures 5 to 8 One end of the second swing arm 10b is connected to the rotating base 22 of the first rotating connection component 20a, and the other end is connected to the rotating base 22 of the second rotating connection component 20b. The rotating bases 22 of the first rotating connection component 20a and the second rotating connection component 20b are both provided with a bearing plate 25. In order to increase the force, one end of the second swing arm 10b is connected to the top of the bearing plate 25 of the first rotating connection component 20a (that is, located above the rotating base 22 of the first rotating connection component 20a), and the other end is connected to the bottom of the bearing plate 25 of the second rotating connection component 20b (that is, located in the middle of the rotating base 22 of the second rotating connection component 20b).

[0071] In the embodiment of the present utility model, please refer to Figure 3 and Figure 4The rotating connection assembly 20 further includes a positioning member 26, the rotating shaft member 21 or the rotating base 22 is provided with a second mounting portion 27, the swing arm member 10 connected to the rotating shaft member 21 or the rotating base 22 provided with the second mounting portion 27 is provided with a third mounting portion 28, and the positioning member 26 is connected between the second mounting portion 27 and the third mounting portion 28 to position the rotating shaft member 21 or the rotating base 22 provided with the second mounting portion 27. In this way, when assembling, it is possible to avoid the rotating shaft member 21, the rotating base 22 and the swing arm member 10 and other components being installed in the wrong direction.

[0072] The positioning member 26 may be configured as a positioning column, the second mounting portion 27 may be configured as a through hole, and the third mounting portion 28 may be configured as a blind hole.
