Description

Technical Field

[0001] The present application relates to the technical field of medical devices, and in particular to a lifting device and an assembly method, and a surgical robot. Background Art

[0002] Minimally invasive surgery refers to a surgical method that uses modern medical devices such as laparoscopes and thoracoscopes and related equipment to perform surgery inside the human body cavity. With the development of robotic technology, minimally invasive surgical robots have emerged. The slave hand component of the surgical robot is the implementation component of the surgical robot to perform surgical operations. Before the surgical operation, preoperative adjustments are required to determine the surgical action position. Preoperative adjustments include the lifting and lowering of the slave hand, which is generally achieved through a lifting device.

[0003] In the related art, the lifting device needs to undergo an overload test process to detect the loadable weight. The lifting device is usually lowered to the lowest point by a lead screw.

[0004] The screw mounting assembly installation point is concentrated at the bottom of the fixed column. The screw mounting assembly rigidity is weak. During the stall current impact test, there is visible displacement on the top of the screw mounting plate.

[0005] However, during the above test, if the motor load is large, due to the close contact between the assembly used to install the screw and the fixed column supporting the lifting of the screw, elastic deformation is likely to occur between the fixed column and the installation assembly, thereby affecting the lifting accuracy of the screw. Summary of the invention

[0006] The embodiment of the present application provides a lifting device and assembly method, and a surgical robot, wherein a main board and a side board are arranged in a housing, and are connected to different positions of the housing through a first mounting member and a second mounting member, respectively, to form a relatively stable frame structure. This can effectively disperse the lead screw load, reduce stress concentration at a single location, and thus improve the rigidity and stability of the overall structure.

[0007] In a first aspect, an embodiment of the present application provides a lifting device, including a housing, a lead screw, a lifting body, and a mounting assembly;

[0008] The housing has a receiving cavity;

[0009] The lead screw is located in the accommodating cavity;

[0010] The lifting body is movably disposed in the accommodating cavity, and the lifting body is connected to the lead screw; the lifting body is configured to move synchronously with the rotation of the lead screw and along the extension direction of the lead screw shaft;

[0011] The installation assembly comprises:

[0012] A main board is located in the accommodating cavity and is extended along the extension direction of the lead screw shaft;

[0013] A side plate, located in the accommodating cavity and connected to the outer side of the main plate;

[0014] A mounting base is located in the accommodating cavity and connected between the main board and the housing, wherein the mounting base has a mounting hole adapted to the end of the lead screw, and the end of the lead screw is connected to the mounting hole;

[0015] A first mounting member connected between the housing and the side plate;

[0016] The second mounting member is connected between the housing and the mainboard; wherein,

[0017] The first mounting member and the second mounting member are respectively connected to different positions of the shell.

[0018] The lifting device provided in the embodiment of the present application forms a relatively stable frame structure by arranging a main board and a side board in the housing and connecting them to different positions of the housing through a first mounting member and a second mounting member, respectively. In this way, the load of the lead screw can be effectively dispersed, and the stress concentration at a single position can be reduced, thereby improving the rigidity and stability of the overall structure.

[0019] The mounting base fixes the end of the screw by adapting to the mounting hole at the end of the screw, effectively reducing the displacement and deformation of the screw under high load conditions, and ensuring that the lifting body can maintain synchronous movement when the screw rotates, thereby improving the accuracy of the lifting device.

[0020] Through the above-mentioned lifting device, the structure is relatively stable and the load distribution is reasonable, which can better resist the impact force that may be generated by the overload test, reduce the displacement and deformation caused by the impact, and thus improve the reliability and durability of the device.

[0021] Finally, the above-mentioned lifting device can be easily assembled and disassembled through modular setting, which is convenient for daily maintenance and inspection.

[0022] In a possible implementation, the housing includes a bottom plate and an outer shell, the bottom plate is connected to one end of the outer shell, the bottom plate and the outer shell are arranged to form the accommodating cavity, and a surface extension direction of the bottom plate is perpendicular to a surface extension direction of the outer shell;

[0023] The first mounting member is connected to the bottom plate, and the second mounting member is connected to the housing;

[0024] The second mounting member and the mounting base are respectively located on two opposite sides of the main board;

[0025] The first mounting member and the mounting base are both located on the same side of the bottom plate.

[0026] Through the above arrangement, the bottom plate is vertically connected to the housing to form a rigid frame, which can effectively resist forces from different directions, reduce deformation and displacement, and ensure the safety and stability of internal components. Support points are set on opposite sides of the motherboard to reduce possible bending and deformation of the motherboard during operation. The forces acting on the motherboard are reduced and dispersed, improving stability and durability. Placing the mounting parts and the base on the same side helps to simplify the structural design and assembly process, while ensuring uniform force distribution on that side, improving the stability and reliability of the overall structure.

[0027] In a possible implementation manner, there are multiple second mounting members, and the multiple second mounting members are all connected between the mainboard and the housing;

[0028] A plurality of the second mounting members are arranged at intervals along the extension direction of the lead screw shaft.

[0029] By arranging the mounting parts at intervals in the direction of the screw, the force is evenly distributed, the possibility of local stress concentration and deformation is reduced, and the bending and torsion resistance of the structure is improved, thereby improving the rigidity and stability of the overall structure.

[0030] In a possible implementation manner, the second mounting member close to the bottom plate includes a mounting body and two clamping portions, wherein the two clamping portions are respectively located on opposite sides of the mounting body and are both located on a side of the mounting body facing the main board;

[0031] The clamping portion abuts against the side plate, the installation body abuts against the main board, and the two clamping portions, the installation body and the main board are interference connected.

[0032] Through the above arrangement, the clamping parts are arranged on both sides of the mounting body, which can provide additional support and fixing points, reduce the displacement and rotation of the mounting parts during operation, and improve the stability of the structure. The interference connection can provide high-strength fixation, reduce the possibility of loosening and vibration, and improve the overall rigidity of the system. The interference connection can eliminate gaps through tight fit, enhance the strength and stability of the connection, and reduce loosening and wear under load and vibration conditions.

[0033] In a possible implementation manner, the first mounting member includes a first mounting portion and a second mounting portion, the first mounting portion abuts against the housing, and the second mounting portion abuts against the side plate;

[0034] An extending direction of a surface of the first mounting portion is perpendicular to an extending direction of a surface of the second mounting portion.

[0035] Through the above settings, the multi-directional support and vertical design provide a more stable fixation, reducing displacement and vibration during operation. The L-shaped structure and vertical design increase the bending and torsion resistance of the mounting parts, reducing possible rotation and deformation during operation.

[0036] In a possible implementation manner, the number of the side panels is two, and the two side panels are respectively located on opposite sides of the main board, and the main board and the two side panels are jointly arranged to form an opening communicating with the accommodating cavity;

[0037] The lifting body is connected to the lead screw through the opening.

[0038] Through the above arrangement, the symmetrical support design helps to disperse the forces acting on the main board, reduce bending and deformation, and improve the overall structural stability. By forming an opening connecting the accommodating cavity, a direct path is provided so that the lifting body can be connected to the lead screw. This design can simplify the mechanical connection, reduce unnecessary intermediate components, and improve the efficiency and reliability of the system.

[0039] In a possible implementation manner, the number of the first mounting members is two, and the two first mounting members are symmetrically arranged along the rotation axis of the lead screw;

[0040] The two second mounting parts are respectively connected to the two side plates, and the two first mounting parts are both connected to the shell.

[0041] Through the above-mentioned arrangement, by symmetrically arranging the first mounting part, the symmetrical arrangement can provide balanced support and fixation, reduce deformation and stress concentration caused by asymmetric loads, and reduce bending and torsional deformation caused by asymmetric loads, ensuring uniform force distribution along the screw direction. By connecting the second mounting part to the side plate, the support points of the side plate are increased, the stress acting on the side plate is dispersed, and the bending and torsion resistance of the structure is improved. By connecting the first mounting part to the bottom plate, the first mounting part provides additional support and fixing points, reduces the deformation of the bottom plate under load, enhances the fixing effect of the bottom plate and the rigidity of the overall structure, and improves the stability of the overall structure.

[0042] In a second aspect, an embodiment of the present application further provides an assembly method of a lifting device, which is used for the lifting device, and the assembly method includes:

[0043] A lead screw is provided and a mounting base, a main board and a side plate are provided, wherein the mounting base, the main board and the side plate are all arranged in a housing, and the mounting base, the main board, the side plate, a first mounting member and a second mounting member are connected to form a mounting assembly;

[0044] Positioning and mounting the end of the lead screw in the mounting hole of the mounting base;

[0045] sequentially connecting the mounting base and the housing, the second mounting member and the housing, and the first mounting member and the housing;

[0046] The lifting body is connected to the lead screw to form the lifting body.

[0047] Through the above settings, the step-by-step assembly method reduces error accumulation and ensures the correct positioning and function of each component. Accurate positioning and connection improve the stability of the overall structure and reduce deformation and vibration during operation. The direct connection design reduces intermediate components, improves the efficiency and accuracy of the system, and is suitable for applications with high precision and high response speed.

[0048] In a possible implementation manner, the mounting base, the main board, the side board, the first mounting member, and the second mounting member are connected to form the mounting assembly, including:

[0049] Connecting the mounting base, the main board and the side board;

[0050] Connecting the first mounting member to the mainboard;

[0051] Connect the second mounting member to the side panel.

Among them, the surgical platform provides a stable foundation, and the design of the robotic arm and the lifting device ensures the stability and reliability of the system, reducing errors and jitters that may occur during the operation. Secondly, the robotic arm enables the lifting device to reach various positions for surgical operations, meet the needs of different surgeries, and provide a wider operating range. In addition, the two ends of the robotic arm are respectively connected to the lifting device and the surgical platform to form a complete transmission chain, which can improve the efficiency and safety of the operation.

[0081] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0082] An embodiment of the present application provides a surgical robot, including a surgical platform, a robotic arm, and a lifting device.

[0083] Specifically, the surgical platform is the basic part of the surgical robot, used to support and fix the entire surgical robot system, and is also the main place for surgical operations.

[0084] As the basic part, the surgical platform can support the robotic arm and lifting device, allowing them to maintain the correct position and angle during the operation, reducing surgical risks caused by vibration or movement, and ensuring that the surgical robot system can operate stably during the operation.

[0085] The robotic arm is a structure that connects the surgical platform and the lifting device, and is used to transmit the movement of the lifting device to the surgical platform. The two ends of the robotic arm are connected to the lifting device and the surgical platform respectively. The robotic arm can accurately transmit the movement of the lifting device to ensure the accuracy and consistency of the surgical operation.

[0086] The lifting device is the end effector of the surgical robot, which realizes the surgical operation through the drive component, the opening and closing component and the circuit component. The movement of the lifting device is transmitted to the surgical platform through the robotic arm.

[0087] Through the above settings, the surgical robot can achieve high-precision surgical operations through precise control of the robotic arm and the lifting device, meet the needs of complex and minimally invasive surgeries, and significantly improve the success rate of the surgery. Among them, the surgical platform provides a stable foundation, and the design of the robotic arm and the lifting device ensures the stability and reliability of the system, reducing errors and jitters that may occur during the operation. Secondly, the robotic arm enables the lifting device to reach various positions of the surgical operation, meet the needs of different surgeries, and provide a wider range of operations. In addition, the two ends of the robotic arm are respectively connected to the lifting device and the surgical platform to form a complete transmission chain, which can improve the efficiency and safety of the operation.

[0088] Reference Figure 1 In a second aspect, the embodiment of the present application provides a lifting device 10. The lifting device 10 includes a housing 100, a lead screw 200, a lifting body 300 and a mounting assembly 400.

[0089] Specifically, the housing 100 has a housing chamber 101. The lead screw 200, the lifting body 300 and the mounting assembly 400 are all located in the housing chamber 101. The housing chamber 101 can provide a protected working environment for the lead screw 200 and the lifting body 300.

[0090] It should be noted that the housing 100 may be made of high-strength materials such as aluminum alloy or stainless steel to provide sufficient structural strength and corrosion resistance.

[0091] Through the above configuration, the lifting device 10 can effectively prevent the intrusion of external pollutants (such as dust and moisture), thereby improving the reliability and durability of the lifting device 10 and the surgical robot. At the same time, the accommodating cavity 101 also helps to reduce the impact of noise and vibration on the outside world and improve the overall performance of the lifting device 10.

[0092] It should be noted that the lead screw 200 is a transmission component of the lifting device 10 , and the precise positioning and stable operation of the lead screw 200 are the basis for achieving precise movement of the lifting body 300 , which is more important for surgical robots that require high-precision operations.

[0093] It is understood that the lead screw 200 can be made of high-strength steel or alloy, with precision-machined threads to ensure high-precision linear motion. The diameter and pitch of the lead screw 200 can be designed according to load requirements and precision requirements, and are not limited here.

[0094] The lifting body 300 is movably disposed in the accommodating cavity 101 and connected to the lead screw 200 ; the lifting body 300 is configured to move synchronously with the rotation of the lead screw 200 and along the extension direction of the rotation axis A of the lead screw 200 .

[0095] It is understood that the lifting body 300 can be made of a lightweight but strong material such as aluminum alloy to reduce inertia and improve response speed.

[0096] It should be noted that the lifting body 300 is usually connected to the lead screw 200 through a nut or a slider mechanism.

[0097] Through the above arrangement, the lifting body 300 and the lead screw 200 move synchronously, which can ensure the smoothness and accuracy of the lifting process, reduce errors caused by asynchrony or offset, and improve overall accuracy and efficiency.

[0098] Reference Figure 2 Specifically, the mounting assembly 400 includes a main board 410 , a side board 420 , a mounting base 430 , a first mounting member 440 and a second mounting member 450 .

[0099] The main board 410 is located in the accommodating cavity 101 and is extended along the extension direction of the rotation axis A of the lead screw 200. The main board 410 can be made of high-strength materials such as steel or aluminum alloy to provide sufficient rigidity and durability. Its size design should match the length of the lead screw 200 to support the entire lifting stroke.

[0100] Through the above arrangement, the main board 410 is used to provide a stable foundation to ensure accurate alignment and support of the lead screw 200 and the lifting body 300. By extending the main board 410 along the lead screw 200, the main board 410 can effectively disperse the load and stress, reduce deformation, and improve the overall accuracy and stability of the lifting device 10.

[0101] The side plate 420 is located in the accommodating cavity 101 and is connected to the outer side of the main plate 410. The side plate 420 can be made of a light but strong material, such as aluminum alloy, to reduce the overall weight and provide additional support.

[0102] The connection between the side panels 420 and the main panel 410 can form a frame structure, which can increase the lateral rigidity and torsion resistance of the mounting assembly 400. In this way, the side panels 420 provide additional support and stability, especially under lateral forces, reducing deformation and displacement of the structure.

[0103] It should be noted that the main board 410 and the side board 420 may be an integrated piece to enhance the structural strength and rigidity of the installation assembly 400 .

[0104] The mounting base 430 is located in the accommodating cavity 101 and connected between the main board 410 and the housing 100. The mounting base 430 has a mounting hole 431 adapted to the end of the lead screw 200. The mounting base 430 is usually made of high-strength metal, and the size of the mounting hole 431 is precisely processed to adapt to the end of the lead screw 200.

[0105] The end of the lead screw 200 is connected to the mounting hole 431 , and the mounting base 430 fixes the end of the lead screw 200 to ensure its positioning accuracy under high load conditions.

[0106] Through the precise design of the mounting hole 431, the mounting base 430 can firmly fix the lead screw 200, reduce possible displacement and deformation during operation, and improve the accuracy of the lifting process.

[0107] The first mounting member 440 is connected between the housing 100 and the side plate 420. It is understood that the first mounting member 440 and the housing 100 and the main board 410 can be connected by high-strength fasteners, such as bolts or rivets, to ensure a firm connection.

[0108] The first mounting member 440 can provide a fixed connection between the side plate 420 and the housing 100, increase the support points, and thus disperse the load. By increasing the support points, the first mounting member 440 can reduce stress concentration and improve the stability and durability of the lifting device 10.

[0109] The second mounting member 450 is connected between the housing 100 and the main board 410. It is understood that the second mounting member 450 and the housing 100 and the main board 410 can be connected by high-strength fasteners, such as bolts or rivets, to ensure a firm connection.

[0110] The second mounting member 450 can provide an additional support point for the side plate 420, and form a multi-point connection with the first mounting member 440 to enhance the overall rigidity. The multi-point connection design effectively disperses the force, reduces the risk of structural deformation, and improves the impact resistance and stability of the lifting device 10 and the surgical robot.

[0111] The first mounting member 440 and the second mounting member 450 are respectively connected to different positions of the housing 100. That is, a relatively stable frame structure can be formed between the first mounting member 440, the second mounting member 450 and the housing 100. In this way, the load of the lead screw 200 can be effectively dispersed, and the stress concentration at a single position can be reduced, thereby improving the rigidity and stability of the overall structure.

[0112] The lifting device 10 has a relatively stable structure and a reasonable load distribution, and can better resist the impact force that may be formed by the overload test, reduce the displacement and deformation caused by the impact, and thus improve the reliability and durability of the device. In addition, the lifting device 10 can be easily assembled and disassembled through a modular setting, which is convenient for daily maintenance and repair.

[0113] Reference Figure 2As an optional embodiment, the housing 100 includes a bottom plate 110 and an outer shell 120. The bottom plate 110 and the outer shell 120 are generally made of high-strength materials such as steel or aluminum alloy to provide sufficient structural strength and durability. The thickness of the bottom plate 110 and the size of the outer shell 120 should be designed to withstand the load.

[0114] The bottom plate 110 is connected to one end of the housing 120, and the bottom plate 110 and the housing 120 are arranged to form a receiving cavity 101, and the surface extension direction of the bottom plate 110 is perpendicular to the surface extension direction of the housing 120. The vertical connection can provide a solid structural foundation to ensure the stability and sealing of the receiving cavity 101.

[0115] Through the above arrangement, the bottom plate 110 and the outer shell 120 are vertically connected to form a rigid frame, which can effectively resist forces from different directions, reduce deformation and displacement, and ensure the safety and stability of internal components.

[0116] The first mounting member 440 is connected to the bottom plate 110, and the connection of the first mounting member 440 provides additional support and stability, thereby enhancing the fixing effect of the bottom plate 110. By connecting the first mounting member 440 to the bottom plate 110, the support points of the bottom plate 110 are increased, the stress is dispersed, the deformation of the bottom plate 110 under load is reduced, and the stability of the structure is improved.

[0117] The second mounting member 450 is connected to the housing 120. The second mounting member 450 provides an additional support point for the housing 120, forms a stable connection with the bottom plate 110, and enhances the overall rigidity.

[0118] By connecting the second mounting member 450 to the housing 120 , an additional fixing point is provided, the possible deformation and displacement of the housing 120 during operation is reduced, and the impact resistance of the system is improved.

[0119] The second mounting member 450 and the mounting base 430 are respectively located on opposite sides of the mainboard 410. In this way, the second mounting member 450 and the mounting base 430 can provide balanced support for the mainboard 410, that is, by setting support points on opposite sides of the mainboard 410, possible bending and deformation of the mainboard 410 during operation can be reduced, and the forces acting on the mainboard 410 can be dispersed to improve stability and durability.

[0120] The first mounting member 440 and the mounting base 430 are both located on the same side of the bottom plate 110. Placing the mounting member and the base on the same side helps to simplify the structural design and assembly process, while ensuring uniform force distribution on the side, and improving the stability and reliability of the overall structure.

[0121] Reference Figure 2As an optional implementation, there are multiple second mounting members 450, and the arrangement of multiple mounting members provides more uniform and dispersed support, thereby enhancing the overall strength and stability of the connection.

[0122] By increasing the number of mounting parts, the stress acting between the mainboard 410 and the housing 120 is dispersed, the load and deformation risk of a single connection point are reduced, and the durability and stability of the structure are improved.

[0123] It should be noted that the number of the second mounting members 450 may be two, three, four, five, six, etc. The embodiment of the present application does not limit the specific number of the second mounting members 450, nor is it limited to the above examples.

[0124] The plurality of second mounting members 450 are connected between the main board 410 and the housing 120; the plurality of second mounting members 450 are arranged at intervals along the extension direction of the rotation axis A of the lead screw 200. The specific intervals between the mounting members can be designed according to the length and load requirements of the lead screw 200 to ensure better force distribution and support effect.

[0125] Through the above arrangement, by arranging the mounting parts at intervals in the direction of the lead screw 200, the force is evenly distributed, the possibility of local stress concentration and deformation is reduced, and the bending and torsion resistance of the structure is improved, thereby improving the rigidity and stability of the overall structure.

[0126] The following description will be made by taking the number of the second mounting members 450 as two as an example, wherein one of the second mounting members 450 is disposed closer to the bottom plate 110 than the other second mounting member 450 .

[0127] Reference Figure 3 As an optional embodiment, the second mounting member 450 close to the bottom plate 110 includes a mounting body 451 and two clamping portions 452. The two clamping portions 452 are respectively located on opposite sides of the mounting body 451 and are both located on the side of the mounting body 451 facing the main board 410.

[0128] By providing the clamping parts 452 on both sides of the mounting body 451, additional support and fixing points can be provided, thereby reducing the displacement and rotation of the mounting part during operation and improving the stability of the structure.

[0129] The clamping portion 452 abuts against the side plate 420 , and the installation body 451 abuts against the main board 410 . The two clamping portions 452 and the installation body 451 are interference connected with the main board 410 .

[0130] It is understood that interference fit can provide high-strength fixation, reduce the possibility of loosening and vibration, and improve the overall rigidity of the system. Interference fit can eliminate gaps through tight fit, enhance the strength and stability of the connection, and reduce loosening and wear under load and vibration conditions.

[0131] It should be noted that the mounting body 451 and the two clamping portions 452 may be an integral part, so as to enhance the structural strength and rigidity of the second mounting member 450 .

[0132] Reference Figure 4 As an optional embodiment, the first mounting member 440 includes a first mounting portion 441 and a second mounting portion 442, the first mounting portion 441 abuts against the housing 100, and the second mounting portion 442 abuts against the side plate 420. It can be understood that when the housing 100 includes the bottom plate 110, the first mounting portion 441 abuts against the bottom plate 110.

[0133] It should be noted that the size and shape of the first mounting portion 441 and the second mounting portion 442 should be designed to match the geometric shapes of the bottom plate 110 and the side plate 420 .

[0134] An "L"-shaped support structure is formed by the contact between the first mounting portion 441 and the bottom plate 110 and the second mounting portion 442 and the side plate 420. This multi-directional support design helps to disperse stress, reduce the impact of single-point load on the structure, and improve overall stability.

[0135] It should be noted that the first mounting portion 441 and the second mounting portion 442 may be an integral piece to enhance the structural strength and rigidity of the first mounting member 440 .

[0136] The surface extension direction of the first mounting portion 441 is perpendicular to the surface extension direction of the second mounting portion 442. By designing the surface extension directions of the two mounting components to be perpendicular, a rigid frame structure is formed. This structure can effectively resist forces from different directions, reduce deformation and displacement, and improve the overall rigidity and stability of the system.

[0137] Through the above settings, the multi-directional support and vertical design provide a more stable fixation, reducing displacement and vibration during operation. The L-shaped structure and vertical design increase the bending and torsion resistance of the mounting parts, reducing possible rotation and deformation during operation.

[0138] Reference Figure 2 As an optional implementation, there are two side panels 420, which are respectively located on opposite sides of the main board 410. By arranging the side panels 420 on opposite sides of the main board 410, a frame structure is formed. This symmetrical support design helps to disperse the force acting on the main board 410, reduce bending and deformation, and improve the overall structural stability.

[0139] The main plate 410 and the two side plates 420 are jointly arranged to form an opening communicating with the accommodating cavity 101 .

[0140] It should be noted that the opening should be designed to be large enough to allow free movement of the lifting body 300 while maintaining the integrity of the structure.

[0141] By forming an opening communicating with the accommodating chamber 101, a direct path is provided so that the lifting body 300 can be connected to the lead screw 200. This design can simplify the mechanical connection, reduce unnecessary intermediate components, and improve the efficiency and reliability of the system.

[0142] The lifting body 300 is connected to the lead screw 200 through an opening. By directly connecting the lifting body 300 and the lead screw 200, intermediate transmission components are reduced, energy loss and error accumulation are reduced, and assembly complexity and maintenance time are reduced.

[0143] Reference Figure 2 As an optional implementation, the number of the first mounting members 440 is two, and the two first mounting members 440 are symmetrically arranged along the rotation axis A of the lead screw 200. The symmetrical arrangement can provide balanced support and fixation, and reduce deformation and stress concentration caused by asymmetric loads.

[0144] By symmetrically arranging the first mounting member 440, uniform force distribution along the direction of the lead screw 200 is ensured, thereby reducing bending and torsional deformation caused by asymmetric loads.

[0145] The two second mounting portions 442 are respectively connected to the two side panels 420. The two side panels 420 can provide additional support to enhance the rigidity of the side panels 420 and the stability of the overall structure.

[0146] By connecting the second mounting portion 442 to the side plate 420, the supporting points of the side plate 420 are increased, the stress acting on the side plate 420 is dispersed, and the bending and torsion resistance of the structure is improved.

[0147] The two first mounting portions 441 are both connected to the housing 100, i.e., the bottom plate 110. By connecting the first mounting portions 441 to the bottom plate 110, the first mounting portions 441 provide additional support and fixing points, reduce deformation of the bottom plate 110 under load, enhance the fixing effect of the bottom plate 110 and the rigidity of the overall structure, and improve the stability of the overall structure.

[0151] S200, positioning and installing the end of the lead screw into the mounting hole of the mounting base;

[0152] It should be noted that the size of the mounting hole 431 should be precisely matched with the end of the lead screw 200, which is usually achieved through precision machining. Through precise positioning and installation, the axis of the lead screw 200 is ensured to be consistent with the movement direction of the lifting device 10, reducing wear and energy loss caused by deviation.

[0153] It is understandable that the housing 100 may also be provided with an adapter hole corresponding to the mounting hole 431, that is, the mounting hole 431 is a through hole, and the end of the lead screw 200 may be penetrated by the mounting hole 431 and matched with the adapter hole.

[0154] S300, sequentially connecting the mounting base and the housing, the second mounting member and the housing, and the first mounting member and the housing;

[0155] The step-by-step connection method ensures that each component is correctly positioned and fixed, improving assembly accuracy and efficiency.

[0156] By connecting in sequence, the accumulation of errors in the assembly process is reduced, the correct position and function of each component is ensured, and the stability of the overall structure is improved.

[0157] S400, connecting the lifting body and the lead screw to form a lifting device.

[0158] By directly connecting the lifting body 300 and the lead screw 200, the intermediate transmission components are reduced, the energy loss and error accumulation are reduced, and the response speed and accuracy of the system are improved.

[0159] Reference Figure 6 As an optional embodiment, the mounting base 430, the main board 410, the side board 420, the first mounting member 440 and the second mounting member 450 are connected to form a mounting assembly 400, including:

[0161] By connecting the mounting base 430, the main board 410 and the side board 420 together to form an overall frame, it is possible to effectively disperse and bear forces from different directions, reduce deformation, and improve the overall structural stability.

[0162] S120, connecting the first mounting component to the mainboard.

[0163] By connecting the first mounting member 440 to the main board 410, additional support is provided, the stress on the main board 410 is dispersed, the deformation under load is reduced, and the stability and durability of the overall structure are improved.

[0164] S130, connecting the second mounting member to the side panel.

[0165] By connecting the second mounting member 450 to the side plate 420, additional support is provided, the stress on the side plate 420 is dispersed, the deformation under load is reduced, and the stability and durability of the overall structure are improved.

[0166] Through the above-mentioned assembly method, the sequence of first assembling the mounting base 430, the main board 410 and the side panel 420, then installing the first mounting member 440, and finally installing the first mounting member 440 can realize modular assembly, and can realize convenient assembly and disassembly, which is convenient for daily maintenance and repair.
