[0032] According to an exemplary embodiment of the present invention, a lifting mechanism is provided.

[0033] Figure 1 FIG. 1 is a side view showing a lifting mechanism 100 according to an exemplary embodiment of the present invention. Figure 1As shown, the lifting mechanism 100 includes a base 101, a supporting device 102, a front block 103, and a control system (not shown). The base 101 is used to fix and support the entire lifting mechanism 100, while the front block 103 is arranged at the front end of the lifting mechanism 100 and is used to carry external components that need to be lifted. One end of the supporting device 102 is connected to the front block 103, and the other end is connected to the base 101 to carry and transmit the force during the lifting process. In addition, the control system (not shown) is used to control the lifting action of the lifting mechanism to achieve precise and stable lifting operation. Specifically, the control system controls the supporting device 102 via a control line, thereby causing the front block 103 to be lifted relative to the base 101. Here, in this exemplary embodiment, the control line is, for example, a Bowden line, which can effectively resist interference from the external environment while transmitting force. However, the present invention is not limited to this, and other wires commonly used in the art can also be used as control lines.

[0034] like Figure 1 As shown, in this exemplary embodiment, the front block 103 is raised and lowered relative to the base 101 by control of a control line from a control system. Figure 1 In the figure, the distance that the front block 103 rises from the lowest point to the highest point, or falls from the highest point to the lowest point, is recorded as S, and S is the stroke range that can be achieved by the lifting mechanism 100 involved in this exemplary embodiment.

[0035] In this exemplary embodiment, the support device 102 is configured so that when the front block 103 moves to the lowest point relative to the base 101, one end of the support device 102 connected to the front block 103 is located below the other end connected to the base 101. More specifically, the support device 102 is configured so that when the front block 103 is at the highest point of the travel range S, the angle between the support device 102 and the horizontal plane is 0 to 90 degrees; and when the front block 103 is at the lowest point of the travel range S, the angle between the support device 102 and the horizontal plane is -90 to 0 degrees (in the range of 0 to 90 degrees). Figure 1 In other words, the support device 102 is configured such that the angle between the support device 102 and the horizontal plane changes from 0 to 90 degrees to -90 to 0 degrees during the movement of the front block 103 from the highest point in the travel range S to the lowest point. By configuring the support device 102 to form a negative angle α, the travel range S of the lifting mechanism 100 can be significantly expanded without changing the overall structural stability of the lifting mechanism 100, thereby adapting to different lifting requirements and being particularly suitable for operating systems requiring a large travel range.

[0036] also, Figure 1 The reference numerals S1, S2, S3 and S4 shown in the figure are connection points between the support device 102 and the front block 103 and the base 101 respectively, which will be described in detail below.

[0037] Figure 2 1 is an exploded view of a lifting mechanism 100 according to an exemplary embodiment of the present invention, showing main components of the lifting mechanism 100 according to the exemplary embodiment.

[0038] like Figure 2 As shown, the support device 102 includes an upper arm 112, a lower arm 122, and a gas spring 132. One end of the upper arm 112 is rotatably connected to the base 101, and the other end is rotatably connected to the front block 103. Similarly, one end of the lower arm 122 is rotatably connected to the base 101, and the other end is rotatably connected to the front block 103. The gas spring 132 has its ends connected to the upper arm 112 and the lower arm 122, respectively. When the front block 103 is raised or lowered relative to the base 101, the gas spring 132 and the lower arm 122 rotate together about the same axis relative to the base 101.

[0039] Specifically, if Figure 2 As shown, in this exemplary embodiment, the upper arm 112 is connected to the front block 103 and the base 101 respectively through the upper arm shaft, that is, Figure 1 The lower arm 122 is connected to the front block 103 and the base 101 respectively through the lower arm shaft, that is, Figure 1 The connection points S2 and S4 are shown in FIG. One end of the gas spring 132 is connected to the upper arm 112 via the gas spring upper shaft 132u. The gas spring upper shaft 132u and the upper arm shaft on the front block 103 side of the upper arm 112 are two independent components. The other end of the gas spring 132 is connected to the lower arm 122 via the gas spring lower shaft 132d, and is also connected to the base 101. In other words, the gas spring lower shaft 132d is also the lower arm shaft on the base 101 side of the lower arm 122, and the two are the same shaft. Therefore, Figure 1 The connection point S2 shown in FIG serves as the connection point between the lower arm 122 and the base 101, and also serves as the connection point between the gas spring 132 and the base 101. According to this structure, when the front block 103 is raised or lowered relative to the base 101, the gas spring 132 and the lower arm 122 rotate coaxially relative to the base 101, thereby eliminating additional transmission mechanisms and connecting components, simplifying the overall structure, and thus reducing the overall size of the device, lowering costs, and improving reliability.

[0040] In some embodiments, the gas spring upper shaft 132u and the upper arm shaft on the front block 103 side of the upper arm 112 can also be set to the same axis, so that when the front block 103 is raised or lowered relative to the base 101, the two rotate coaxially. In this case, the overall structure can be further simplified and the overall size of the device can be reduced.

[0041] In addition, if Figure 2As shown, the lifting mechanism 100 further includes a limiting portion 104 and a base cover 105. These two parts will be described in detail below.

[0042] First, based on Figures 1 to 3 The limiting portion 104 is described in detail. Figure 1 and Figure 2 As shown, by providing a limit portion 104 in the lifting mechanism 100, it is possible to ensure that the angle between the front block 103 and the horizontal plane changes from 0 to 90 degrees to -90 to 0 degrees during the process of moving the front block 103 from the highest point to the lowest point in the travel range S, and the front block 103 can be prevented from continuing to descend when it descends to the lowest point, thereby avoiding equipment damage or safety accidents caused by excessive descent.

[0043] The limiting portion 104 can be provided on any one of the base 101, the supporting device 102, and the front block 103, or can be provided on multiple thereof. In some embodiments, when the limiting portion 104 is provided on the base 101, when the front block 103 moves to the lowest point relative to the base 101, the movement of the supporting device 102 is limited by the limiting portion 104, thereby limiting the descent of the front block 103. In this case, for example, a fixed mechanical stop can be provided on the base 101. When the front block 103 descends to the lowest point, the lower arm of the supporting device 102 contacts the mechanical stop, thereby preventing further descent. Alternatively, in some embodiments, the limiting portion 104 can be provided on the front block 103. When the front block 103 moves to the lowest point relative to the base 101, the further descent of the front block 103 is limited by the limiting portion 104 provided therein, thereby limiting the descent of the front block 103. In this case, for example, a fixed mechanical stopper may be provided inside the front block 103 , and when the front block 103 descends to the lowest point, the upper arm of the support device 102 contacts the mechanical stopper, thereby preventing the front block 103 from descending further.

[0044] Alternatively, in some embodiments, the limiting portion 104 may be provided on the support device 102. When the front block 103 moves to the lowest point relative to the base 101, the movement of the support device 102 is limited by the limiting portion 104 provided therein, thereby limiting the descent of the front block 103. In this exemplary embodiment, an example in which the limiting portion 104 is provided on the support device 102 is shown, which will be described in further detail below.

[0045] Figure 3 FIG. 1 is a partial enlarged view showing the position limiting portion 104 in the lifting mechanism 100 according to an exemplary embodiment of the present invention. Figure 3As shown, the limiting portion 104 further includes a limiting member 104a and a limiting member 104b. The limiting member 104a is provided on the upper arm 112, and the limiting member 104b is provided on the lower arm 122. When the front block 103 moves to the lowest point relative to the base 101, the limiting member 104a and the limiting member 104b abut against each other, thereby preventing the front block 103 from continuing to move downward. There is no particular restriction on the shape and setting position of the limiting member 104a and the limiting member 104b, as long as the limiting function can be achieved. In addition, in some embodiments, only one of the limiting members 104a and 104b can be provided as the limiting portion 104. In the case where only one of them is provided, when the front block 103 moves to the lowest point relative to the base 101, the limiting member 104a (or 104b) abuts against the lower arm (or upper arm), thereby preventing the front block 103 from continuing to move downward.

[0046] Furthermore, the position-limiting portion 104 is not limited to a mechanical stopper; other methods such as limit switches, elastic buffers, and magnetic limiters may also be employed, as long as they can achieve the position-limiting function. Furthermore, in some embodiments, the position-limiting portion 104 may be configured as a modular assembly, allowing for quick disassembly and assembly of different modules to accommodate different travel ranges, thereby enabling rapid adaptation to different systems.

[0047] According to the above structure, the lifting mechanism can achieve a larger stroke range while maintaining a compact size, and can be applied to application scenarios that require both small size and a large stroke range, thereby improving the convenience of operation.

[0048] The following is based on Figure 4 The internal structure of the lower arm 122 will be described in detail. Figure 4 1 is a perspective view showing the internal structure of the lower arm 122 in the lifting mechanism 100 according to an exemplary embodiment of the present invention. Figure 4 , the upper arm 112 is removed to expose the interior of the lower arm 122 , and the structure related to the lower arm 122 and the gas spring 132 is mainly shown, and unnecessary illustrations related to other structures are omitted.

[0049] like Figure 4As shown, a reserved space is provided within the lower arm 122 of the support device 102 for accommodating and installing an additional elastic member 132s. This reserved space is configured to allow the additional elastic member 132s and the gas spring 132 to jointly support the movement of the upper arm 112 and the lower arm 122 around the same axis. In other words, fixed points for installing the additional elastic member 132s are reserved on the upper gas spring shaft 132u and the lower gas spring shaft 132d of the gas spring 132, allowing the additional elastic member 132s to rotate together around the same axis, thereby maintaining good synchronous movement between the two and improving the smoothness and precision of the lifting operation. In addition, when the additional elastic member 132s is installed according to the system load requirements, the control line from the control system is only connected to the gas spring 132, and not to the additional elastic member 132s.

[0050] The additional elastic member 132s is an elastic component that can be added according to actual needs to provide additional elastic compensation. The additional elastic member 132s works in conjunction with the original gas spring to form a composite elastic support system, providing a wider load adaptation range and a smoother support effect. In some embodiments, the additional elastic member 132s can be an elastic member such as a spring or an elastic rope. The reserved space can be set according to the type and size of the additional elastic member to be installed. For example, in the case where the additional elastic member 132s is a spring, the reserved space needs to be wide enough to accommodate its diameter and long enough to accommodate its compression or stretching length. Preferably, the additional elastic member 132s is a gas spring. In this case, the gas spring 132 connected to the control line can be called the main gas spring, and the gas spring 132s not connected to the control line can be called the auxiliary gas spring. The two work together to adapt to systems with large loads.

[0051] Furthermore, in some embodiments, a quick-installation structure, such as a quick-release clamp or snap-on design, can be provided within the reserved space to further simplify the assembly and disassembly process of the additional elastic member. In some embodiments, a multi-stage elastic support system can be designed to combine additional elastic members of varying stiffness to accommodate a wider range of application scenarios.

[0052] Thus, according to the above structure, when the lifting mechanism 100 is applied to systems with different load sizes, the additional elastic member can be quickly and easily installed or removed to adapt to the different load systems. Therefore, the lifting mechanism 100 with this structure has flexible configuration capabilities and can be quickly and easily adjusted to meet the specific needs of different systems and different users.

[0053] The following is based on Figure 5 and Figure 6 The base cover 105 mentioned above will be described in detail.

[0054] Figure 51 is a perspective view showing a state in which the base cover 105 is mounted on the base 101 in the lifting mechanism 100 according to an exemplary embodiment of the present invention. Figure 6 1 is an exploded view showing a base 101 and a base cover 105 in a lifting mechanism 100 according to an exemplary embodiment of the present invention.

[0055] like Figure 5 As shown, the lifting mechanism 100 further includes a base cover 105. The base cover 105 is slidably fixed to the lower arm 122 and the base 101, and is configured to slide up and down relative to the base 101 as the front block 103 is raised or lowered relative to the base 101.

[0056] First, the base cover 105 will be described. Figure 5 and 6 As shown, the base cover 105 includes a bottom plate 105a, two wings 105b and a protrusion 105c. The two wings 105b are connected to the bottom plate 105a, and the protrusion 105c is provided on the wings 105b. Figure 5 , the case where three convex portions 105c are provided on each of the two wing portions 105b is shown. Figure 5 As shown, one of the three protrusions 105c is formed on the upper end side of the wing 105b, and the other two protrusions 105c are formed on the lower end side of the wing. However, the present invention is not limited to this, as long as the protrusion 105c is provided on at least one of the two wings 105b. In some embodiments, three protrusions 105c can be provided on only one of the two wings 105b. Alternatively, in some embodiments, three protrusions 105c can be provided on one of the two wings 105b, and one or two or more protrusions 105c can be provided on the other. Alternatively, in some embodiments, more protrusions 105c can be provided on each of the two wings 105b. In addition, the formation position of each protrusion 105c is not limited to Figure 5 The position shown can be set at any position as long as the base cover 105 can slide smoothly relative to the base 101.

[0057] Next, the corresponding structures of the base 101 and the lower arm 122 connected to the base cover 105 are described. Figure 6 As shown, the base 101 includes two walls 101a, and base guide rails 101b are provided on the inner sides of the two walls 101a. As described above, when the base cover 105 is provided with the protrusion 105c on only one of the two wings 105b, the base guide rail 101b can be provided on the inner side of only one of the two walls 101a. When the base cover 105 is provided with the protrusion 105c on both wings 105b, the base guide rail 101b is provided on both walls 101a.

[0058] Furthermore, if Figure 5 As shown, lower arm guide rails 122a are provided on both sides of the lower arm 122. Figure 5 As shown, when the two wings 105b are each provided with three protrusions 105c, the upper end of the base cover 105 is slidably fixed to the lower arm guide rail 122a via the protrusions 105c, and the lower end of the base cover 105 is slidably fixed to the base guide rail 101b via the protrusions 105c. As the front block 103 is raised or lowered relative to the base 101, the protrusions 105c formed on the upper end side slide along the lower arm guide rail 122a, and the protrusions 105c formed on the lower end side slide along the base guide rail 101b.

[0059] Furthermore, in this exemplary embodiment, the protrusion 105c is formed by a cover pin inserted into and fixed to the wing 105b, but this is not limiting. In some embodiments, the protrusion 105c can be integrally formed with the wing 105b. Furthermore, the shape of the protrusion 105c can be designed according to actual needs, for example, it can be spherical or cylindrical to reduce friction and improve sliding efficiency. Furthermore, in some embodiments, the protrusion 105c can be made of or coated with a wear-resistant material to reduce wear and extend its service life.

[0060] According to the above structure, by providing a base cover that slides up and down relative to the base as the front block rises and falls relative to the base, the exposed cables are always shielded during the lifting process, reducing the risk of accidental contact between operators or external objects and ensuring the stability of the device's operation. Furthermore, the appearance of the lifting mechanism is more neat and orderly, improving the overall aesthetics of the product.

[0061] The following is based on Figure 7 The cable storage in this exemplary embodiment will be briefly described. Figure 7 1 is a front view showing the outer surface structure of the lower arm 122 in the lifting mechanism 100 according to an exemplary embodiment of the present invention, and shows the specific structure of the outer surface of the lower arm 122 when the front block 103 of the lifting mechanism 100 rises.

[0062] like Figure 7 As shown, grooves 122b are provided on both sides of the outer surface of the lower arm 122 for fixing cables on both sides of the outer surface of the lower arm 122. The cables mentioned here are power cables, signal cables, etc. used in the control system except control cables.

[0063] In some embodiments, a cable tie or the like can be used to pass through the groove 122b to secure the cable to both sides of the outer surface of the lower arm 122. The number of grooves 122b can be designed based on actual needs. For example, in some embodiments, one groove 122b can be provided on each side of the outer surface of the lower arm 122. Alternatively, in some embodiments, more grooves 122b can be provided on each side of the outer surface of the lower arm 122 to achieve a better securing effect and further reduce wear on the cable. In addition, the cable tie can be made of a wear-resistant material such as nylon, which can be used as a material commonly used in the art.

[0064] Furthermore, in some embodiments, long grooves 122c ( Figure 7 The long slot 122c is shown filled with cables and is therefore indicated in parentheses below the system cables. The long slot 122c allows the cables to be threaded and engaged, thereby better securing them and further reducing cable wear. Furthermore, the shape and size of the long slot 122c are not particularly limited and can be designed based on actual needs.

[0065] Furthermore, in some embodiments, a narrow slot 122d is provided in the center of the outer surface of the lower arm 122, extending along its length. Passing the control wire through and into the narrow slot 122d allows for more secure fixation. The shape and size of the narrow slot 122d are not particularly limited and can be designed based on actual needs.

[0066] According to this structure, by setting grooves, long grooves and narrow grooves for different purposes on the outer surface of the lower arm, the exposed cables can be stored in an orderly manner on the outer surface of the lower arm, which not only ensures the safety of the cables or control lines, but also greatly facilitates subsequent maintenance.

[0067] According to yet another exemplary embodiment of the present invention, a medical device is provided. Figure 8 1 is a schematic diagram showing a medical device 1000 according to another exemplary embodiment of the present invention. Figure 8 As shown, the medical device 1000 includes the aforementioned lifting mechanism 100. The medical device with the aforementioned lifting mechanism 100 can address the deficiencies in the prior art, achieve compatibility between a small size and a large stroke, quickly adapt to different loads, optimize cable management, and enhance maintenance convenience.

[0068] Furthermore, in some embodiments, the medical device 1000 includes at least one of an ultrasound imaging device, an anesthesia machine, a monitoring device, an electrocardiograph, and a medical cart. The present invention can be applied to various medical environments, such as hospitals, clinics, and operating rooms, and can meet the needs of various medical devices described above.
