Description

TECHNICAL FIELD

[0001] The embodiment of the present application relates to the field of medical equipment, in particular to a damping-adjustable rotary module. BACKGROUND

[0002] In the medical robot industry, doctors need to observe the display interface (or instrument interface) at different angles during surgery, so a structure is needed to realize the rotation function of the component, and the rotation to the appropriate angle can realize stable stop.

[0003] At present, various damping rotation structures are used on the market, mainly divided into two categories: power control mode and manual control mode. The manual control damping rotation structure mainly uses damping bearings, adjusting plungers, friction damping and electromagnetic brakes, but the above various damping rotation structures have various defects, for example, the power rotation structure must use a set of motor or air cylinder as the rotation power, which has high cost, large size and needs wiring, and the manual control damping rotation structure has the defects of laborious rotation, inability to adjust the size of the damping and timely control the stop rotation, easy to jam during rotation, complex structure and inconvenient installation. CONTENT OF THE INVENTION

[0004] The embodiment of the present application provides a damping-adjustable rotary module with adjustable damping and simple structure.

[0005] The embodiment of the present application provides a damping-adjustable rotary module, comprising:

[0006] a base;

[0007] a rotating component rotatably arranged on the base;

[0008] a friction plate arranged axially between the rotating component and the base;

[0009] an adjusting component comprising an adjusting rod, one end of the adjusting rod being axially arranged through the rotating component and abutting against the friction plate, and the depth of the adjusting rod arranged through the rotating component being adjusted to adjust the friction damping between the friction plate and the base.

[0010] It can be understood that the friction between the friction plate and the base generates damping, the depth of the adjusting rod arranged through the rotating component is adjusted to control the pressure of the adjusting rod on the friction plate, so as to adjust the friction damping between the friction plate and the base to the required damping, so that the rotating component can be controlled to stop in time, and the damping adjusting structure is simple, the adjusting mode is simple and efficient.

[0011] In an implementation, the rotating assembly comprises a rotating shaft rotatably mounted on the base, and an auxiliary platform protruding in a circumferential direction is arranged on the rotating shaft; a product seat is fixedly arranged on the rotating shaft, and one end of the adjusting rod penetrates the product seat and the auxiliary platform in sequence and abuts against the friction plate, and the other end is positioned against the side of the auxiliary platform away from the friction plate. It can be understood that the auxiliary platform is arranged to enable the adjusting rod to be stably positioned in cooperation with the rotating shaft, thereby avoiding disengagement of the adjusting rod from the rotating shaft.

[0012] In an implementation, the adjusting rod is threadedly connected with the auxiliary platform. The threaded connection simplifies the structure of the adjusting rod and the rotating shaft, and the penetration depth of the adjusting rod can be adjusted by simply rotating the adjusting rod, which is simple and efficient.

[0013] In an implementation, a limiting hole is arranged on the side of the auxiliary platform facing the friction plate, and the adjusting assembly further comprises an elastic member, which is sleeved on the adjusting rod and partially located in the limiting hole. It can be understood that the limiting hole limits the elastic member in the radial direction, thereby preventing the elastic member from being skewed and ensuring that the elastic member applies vertical pressure to the friction plate.

[0014] In an implementation, a limiting boss is arranged on the adjusting rod, and one end of the elastic member abuts against the friction plate and the other end abuts against the limiting boss. It can be understood that the limiting boss facilitates the adjusting rod to apply force to the elastic member when the penetration depth is adjusted, and the elastic member synchronously applies pressure to the friction plate, thereby preventing the elastic member from disengaging from the adjusting rod and causing adjustment failure.

[0015] In an implementation, the rotating assembly further comprises a pressure applying bottom plate arranged between the friction plate and the adjusting rod and connected with the friction plate, and a limiting groove is arranged on the pressure applying bottom plate and corresponds to the limiting hole in position, and one end of the elastic member abuts against the limiting boss and the other end abuts against the limiting groove. The pressure applying bottom plate balances the pressure applied by the adjusting rod to the friction plate, so that the friction plate is subjected to more balanced force, thereby generating balanced damping.

[0016] In an implementation, the pressure applying bottom plate is sleeved on the rotating shaft, a positioning protrusion is arranged on the circumferential side wall of the rotating shaft, a corresponding positioning groove is arranged on the side wall of the pressure applying bottom plate opposite to the rotating shaft, and the positioning protrusion extends into the positioning groove to be positioned in cooperation. It can be understood that the positioning protrusion and the positioning groove can quickly assemble the pressure applying bottom plate of the rotating shaft, and prevent relative displacement between the rotating shaft and the pressure applying bottom plate from affecting the generation of damping between the friction plate and the base.

[0017] In an implementation, the adjusting assembly is provided in multiple groups, and the multiple groups of adjusting assemblies are uniformly arranged along the circumferential direction of the rotating assembly. It can be understood that the multiple groups of adjusting assemblies are arranged and uniformly arranged along the circumferential direction of the rotating assembly, that is, multiple force application points are increased, and uniform damping in each direction is ensured to stably stop the rotating assembly.

[0018] In an implementation, the rotating module further comprises a limiting assembly, the limiting assembly comprising: a limiting rod fixed on the outer circumferential side wall of the rotating shaft; a first stop column fixed on the base; and a second stop column fixed on the base, the first stop column and the second stop column defining an angle range of rotation of the limiting rod. Such an arrangement can prevent excessive rotation of the rotating assembly and can force the rotating assembly to stop when excessive rotation occurs.

[0019] In an implementation, the rotating module further comprises a slewing support bearing, the slewing support bearing comprising a rotatingly connected inner bearing ring and an outer bearing ring, the outer bearing ring being fixedly installed on the base and located between the base and the friction plate, and the rotating assembly being fixedly connected with the inner bearing ring.

[0020] Based on the above-mentioned implementations, the damping-adjustable rotating module provided by the present application comprises a friction plate, a base, an adjusting rod, and a rotating assembly for driving a product to rotate. Friction between the friction plate and the base generates damping. The pressure of the adjusting rod on the friction plate is controlled by adjusting the penetration depth of the adjusting rod in the rotating assembly, so as to adjust the friction damping between the friction plate and the base to the required damping. In this way, the rotating assembly can be controlled to stop in time. The structure for adjusting the damping is simple, the adjustment range is large, the adjustment method is simple and efficient. The friction plate and the base are in surface contact, the contact area is wider, and the risk of jamming is eliminated compared with the point contact method. The end of the adjusting rod is exposed outside the rotating assembly, the view is not blocked during adjustment, and the adjustment is more convenient. The overall rotating module adjusts the damping size by a mechanical adjustment method without the need for external power, and the cost is lower. BRIEF DESCRIPTION OF DRAWINGS

DETAILED DESCRIPTION

[0032] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without any creative work fall within the scope of protection of the present application.

[0033] ​​​​​In the description of the present application, it should be understood that the terms "center", "longitudinal", "transverse", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "axial", "radial", "circumferential" and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and therefore cannot be understood as indicating or implying that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as limiting the present application.

[0034] In the present application, unless otherwise explicitly specified and limited, the terms "mounting", "connection", "connection", "fixing" and the like should be understood broadly, for example, it can be fixed connection, or detachable connection, or integral; it can be mechanical connection, or electrical connection, or communication connection; it can be direct connection, or indirect connection through intermediate medium, or internal communication of two elements or interaction relationship of two elements, unless otherwise explicitly limited. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances. The technical solutions of the present application are described in detail below with specific examples. The following specific examples can be combined with each other, and the same or similar concepts or processes can not be described in detail in some examples.

[0035] Applicants have studied various damping rotation structures on the market and found that damping rotation structures are mainly divided into power control mode and manual control mode, but both have disadvantages, such as complex adjustment of damping or inability to stop in time. The specific shortcomings are as follows:

[0036] 1. The power rotation structure must use a set of motors or air cylinders as the rotation power, which has high cost, large size and needs wiring; 2. The electromagnetic brake structure is disconnected when rotating and stopped when braking, which is generally installed at the center and is not convenient for wiring due to its own characteristics; 3. The damping bearing rotation structure has no reverse resistance, which may be laborious to rotate or unable to stop at the position, and the operator can only adjust the rotation angle again after rotating back in the case of over-rotation, which takes a long time to operate; 4. The adjusting plunger rotation structure mainly selects a set of (multiple products) ball head plungers to press the outer cylindrical surface of the rotation module, which is mostly a metal ball head directly contacting the rotation module, and the contact mode is point contact, and it is difficult to adjust the force of multiple ball head plungers to the same size, which may be stuck during rotation; 5. The friction damping rotation structure mostly selects O-ring as the friction material, which has a complex structure and is not convenient to adjust and install.

[0037] Based on the above problems, the applicant designs a rotation module with adjustable damping, as shown in Figure 1 and Figure 2 ​Figure 1 Figure 1 is a schematic view of a structure of a rotation module with adjustable damping according to an embodiment of the present application, Figure 2 Figure 1 is a schematic view of a structure of a rotation module with adjustable damping according to an embodiment of the present application, Figure 1 is a schematic view of a structure of a rotation module with adjustable damping according to an embodiment of the present application, wherein the rotation module comprises a base 10, a rotation assembly 20, a friction plate 70 and an adjusting assembly 30. The rotation assembly 20 is rotatably arranged on the base 10. The friction plate 70 is arranged axially between the rotation assembly 20 and the base 10. The friction plate 70 is connected with the rotation assembly 20 and can rotate with the rotation assembly 20. The adjusting assembly 30 comprises an adjusting rod 31. One end of the adjusting rod 31 penetrates the rotation assembly 20 axially and abuts against the friction plate 70. The damping between the friction plate 70 and the base 10 is increased by pressing the friction plate 70 through the adjusting rod 31. The damping between the friction plate 70 and the base 10 can be adjusted to the required strength by adjusting the penetration depth of the adjusting rod 31 in the rotation assembly 20. After the rotation assembly 20 is controlled to rotate to a required angle and no longer provides a pushing force, the rotation assembly 20 can be automatically stopped stably because the damping reaches the required strength at this time. It can be understood that the pressure of the adjusting rod 31 on the friction plate 70 is controlled by adjusting the penetration depth of the adjusting rod 31 in the rotation assembly 20, so that the damping between the friction plate 70 and the base 10 is adjusted to the required damping. After the pushing force is stopped, the rotation assembly 20 is automatically stopped. The structure for adjusting the damping is simple, the adjusting mode is simple and efficient. It should be noted that the friction plate 70 and the base 10 are in surface contact, the contact area is wider, and the risk of being stuck is eliminated compared with the point contact mode. The end of the adjusting rod 31 is exposed outside the rotation assembly 20, the view is not blocked during adjustment, and the adjustment is more convenient. The rotation module as a whole adjusts the damping by a mechanical adjusting mode, does not need external power, has a lower cost, and adjusts the pressure on the friction plate 70 by controlling the penetration depth of the adjusting rod 31 in the rotation assembly 20. The pressure adjustment range is large, and the friction force can reach more than 100N.

[0038] Optionally, the friction plate 70 is made of any one of polyurethane, super glue, rubber and the like. Of course, the friction plate 70 can also be a copper sheet, a POM plate, a nylon plate and the like.

[0039] In an embodiment, as shown in Figure 4As shown, the rotating module further comprises a slewing support bearing 60, the slewing support bearing 60 comprises a rotatingly connected inner bearing ring 61 and an outer bearing ring 62, the outer bearing ring 62 is fixedly installed on the base 10 and located between the base 10 and the friction plate 70, the rotating assembly 20 is fixedly connected with the inner bearing ring 61, due to the characteristics of the slewing support bearing 60, the rotating assembly 20 is fixedly connected with the inner bearing ring 61 to realize installation, and can rotate relative to the base 10, the outer bearing ring 62 is fixed on the base 10, so that the friction between the friction plate 70 and the end face of the outer bearing ring 62 generates damping to stop the rotating assembly 20. Compared with the way of generating damping by directly rubbing with the base 10, the friction effect is better, the wear of the friction plate 70 is smaller, and it is beneficial to reduce noise. In other embodiments, other types of bearings can be used instead.

[0040] As Figure 4 and Figure 5 shown, the rotating assembly 20 comprises a rotating shaft 21 and a product seat 23, the rotating shaft 21 is rotatably installed on the base 10, specifically, one end of the rotating shaft 21 is fixedly connected with the inner bearing ring 61, and the other end is fixedly connected with the product seat 23; The rotating shaft 21 is provided with an auxiliary table 22 protruding in the circumferential direction thereof, in this embodiment, the auxiliary table 22 is directly protruded and formed integrally on the circumferential side wall of the rotating shaft 21, one end of the adjusting rod 31 is sequentially provided through the product seat 23 and the auxiliary table 22 and abuts against the friction plate 70, so that the friction force between the friction plate 70 and the base 10 can be adjusted by controlling the spacing between the adjusting rod 31 and the friction plate 70, the other end of the adjusting rod 31 is positioned in cooperation with the side of the auxiliary table 22 away from the friction plate 70, which is beneficial to prevent the adjusting rod 31 from moving excessively towards the friction plate 70. In other embodiments, the auxiliary table can also be a separate component installed on the rotating shaft.

[0041] Optionally, as Figure 4 shown, the adjusting rod 31 is threadedly connected with the auxiliary table 22, so that the threaded adjusting rod 31 can control the penetration depth of the adjusting rod 31 to adjust the friction damping between the friction plate 70 and the base 10 / outer bearing ring 62, and the adjusting mode is simple.

[0042] As Figure 4 and Figure 5As shown, the auxiliary platform 22 has a limiting hole 221 on the side facing the friction plate 70. The adjusting assembly 30 also includes an elastic element 32, which is sleeved on the adjusting rod 31 and partially located within the limiting hole 221. One end of the elastic element 32 abuts against the adjusting rod 31, and the other end abuts against the friction plate 70. The elastic element 32 increases the flexible pressure on the friction plate 70, and can also replenish the pressure on the friction plate 70 in a timely manner during use, so that the friction plate 70 is subjected to balanced force and the resulting damping is stable. The limiting hole 221 limits the elastic element 32 radially, so that the elastic element 32 can contract along the hole wall of the limiting hole 221, preventing the elastic element 32 from shifting.

[0043] In one embodiment, the elastic element 32 is configured as a spring; in other embodiments, the elastic element 32 may also be configured as other elastic structures.

[0044] Optional, such as Figure 4 As shown, a limiting boss 311 is provided on the adjusting rod 31, so that one end of the elastic element 32 abuts against the friction plate 70 and the other end abuts against the limiting boss 311. When adjusting the depth of the adjusting rod 31 through the auxiliary platform 22, the limiting boss 311 applies pressure to the elastic element 32, which can compress the elastic element 32 synchronously, and then apply pressure to the friction plate 70 synchronously, so as to achieve the effect of rapid adjustment of damping.

[0045] In one embodiment, such as Figure 4 As shown, the adjusting rod 31 includes a separately configured adjusting screw 312 and a spring post 313. The adjusting screw 312 is a screw or threaded rod structure, and the finished structure requires no processing, making it easy to obtain and reducing the cost of the module. The elastic element 32 is sleeved on the spring post 313. The end of the adjusting rod 31 near the friction plate 70 abuts against the spring post 313, which is used to increase the distance between the spring post 313 and the friction plate 70. A limiting boss 311 is provided on the spring post 313, and the elastic element 32 is limited between the limiting boss 311 and the friction plate 70.

The limiting groove 41 and the limiting hole 221 corresponding in position are matched to limit the elastic member 32 in the circumferential direction, so as to avoid the position of the elastic member 32 from being deviated to cause the deviation of the force direction.

[0047] Optionally, as shown in Figure 5 As shown, the limiting groove 41 is provided with an avoiding hole 43 extending in the axial direction, the adjusting rod 31 penetrates through the limiting hole 221 and can move in the avoiding hole 43, by arranging the avoiding hole 43, the pressing bottom plate 40 can avoid hindering the penetration depth of the adjusting rod 31. It should be noted that the diameter of the avoiding hole 43 is smaller than the diameter of the elastic member 32, so as to prevent the elastic member 32 from entering the avoiding hole 43.

[0048] As shown in Figure 6 As shown, the circumferential side wall of the rotating shaft 21 is provided with a positioning protrusion 211, and the side wall opposite to the rotating shaft 21 of the corresponding pressing bottom plate 40 is provided with a positioning groove 42, the positioning protrusion 211 is clamped into the positioning groove 42 to be matched and positioned, so as to realize the circumferential positioning of the rotating shaft 21 and the pressing bottom plate 40, which facilitates the assembly of the rotating shaft 21 and the pressing bottom plate 40 and prevents the relative displacement of the two, the rotating shaft 21, the pressing bottom plate 40 and the friction plate 70 are combined to form a whole, so that the damping between the friction plate 70 and the base 10 can quickly and stably stop the rotating shaft 21. In other embodiments, the positioning protrusion can also be arranged on the inner side wall of the pressing bottom plate, and the circumferential outer side wall of the corresponding rotating shaft is provided with a positioning groove matched with the positioning protrusion.

Specifically, the through wiring channel 212 is arranged in the axial direction on the product base 23 and the rotating shaft 21.

[0050] As shown in Figure 6 and Figure 7As shown, the adjusting assembly 30 is provided in multiple groups, and the multiple groups of adjusting assembly 30 are evenly arranged along the circumference of the rotating assembly 20, so that the pressure applied by the adjusting assembly 30 on the friction plate 70 is more balanced.
