DETAILED DESCRIPTION

[0032] The present invention will be further described below in conjunction with the accompanying drawings.

[0033] This embodiment discloses an operating console 1000, which is used in a cab or control room of a mechanical device. Figure 1The operating platform 1000 includes a seat 100, a base assembly 200, an operating armrest 300 and a footrest assembly 400. The seat 100 is used for a user to sit on, and the base assembly 200 is arranged under the seat 100 to drive the seat 100 to rotate circumferentially, move horizontally and lift vertically. The operating armrest 300 is connected to the base assembly 200 and is arranged on the side of the seat 100; buttons and rockers are arranged on the operating armrest 300 for the user to operate the mechanical equipment.

[0034] The operating armrest 300 can be raised and lowered and horizontally slid relative to the seat 100 to adjust the position of the operating armrest 300, so as to facilitate the user to operate the mechanical equipment. The foot pad assembly 400 is connected to the front side of the base assembly 200, and the foot pad assembly 400 is used for placing the human foot. The foot pad assembly 400 is suitable for rotating relative to the base assembly 200 to adjust the inclination angle.

[0035] When the user needs to work in a sitting position, the user can sit on the seat 100, operate the mechanical equipment through the operating armrests 300 around the seat 100, and drive the seat 100 to rotate, move horizontally, and rise and fall vertically through the base assembly 200 to adjust the posture of the seat 100 to meet the sitting posture requirements of different users; at the same time, the foot pad assembly 400 can be rotated relative to the base assembly 200 so that the foot pad assembly 400 forms a certain angle with the horizontal plane to adapt to the situation where the human foot is extended forward and the rear footboard is tilted forward and upward.

[0036] When the user sits for a long time or needs to stand to obtain a better working view, the user can work in a standing position. At this time, the user stands on the foot pad assembly 400 in front of the seat 100, and the foot pad assembly 400 rotates relative to the base assembly 200 to adjust the support angle for the user. The base assembly 200 drives the operating armrest 300 to rise and fall, and at the same time, the operating armrest 300 rises and falls and slides horizontally relative to the seat 100, so that the operating armrest 300 extends to both sides of the standing body, so that the user can operate the mechanical equipment in a standing position.

[0037] Therefore, the operating table 1000 of the present invention can not only adjust the posture of the seat 100 to meet the sitting posture requirements of different users, but also adapt to the needs of users working in a standing position, thereby improving the comfort of users when using it.

[0038] Reference Figure 1 and Figure 2 The base assembly 200 includes a rotating mechanism 210, a translation mechanism 220 and a lifting mechanism 230 which are interconnected. The rotating mechanism 210 is used to drive the seat 100 to rotate circumferentially, the translation mechanism 220 is used to drive the seat 100 to move horizontally, and the lifting mechanism 230 is used to drive the seat 100 to move vertically.

[0039] In this embodiment, the translation mechanism 220 includes a ground rail 221, a translation platform 222, and a translation electric push rod 223. The translation ground rail 221 is fixedly arranged in the cab or control room along the front-to-back direction, where the front refers to the direction of the seat 100 facing the user, and the rear refers to the direction of the seat 100 away from the user. The translation platform 222 is connected to the ground rail 221 so as to be slidable forward and backward, and the translation electric push rod 223 is connected between the ground rail 221 and the translation platform 222, and is used to drive the translation platform 222 to slide on the ground rail 221.

[0040] There are two parallel ground rails 221, and the two ground rails 221 are provided with a slide groove 224 on the opposite sides. The two sides of the translation platform 222 have two side plates 225 arranged in parallel on the outside of the two ground rails 221. The side of the side plate 225 facing the ground rail 221 is rotatably connected with a translation roller 226, and the translation roller 226 is limited in the slide groove 224 and can roll along the extension direction of the slide groove 224. Therefore, the translation roller 226 cooperates with the slide groove 224 to reduce the resistance of the translation platform 222 when sliding on the ground rail 221, so that the translation platform 222 moves more stably and smoothly.

[0041] Reference Figure 2 and Figure 3 A plurality of connecting plates 227 are connected between the two ground rails 221 to connect the two ground rails 221 as a whole and enhance the structural strength. The translation electric push rod 223 is arranged parallel to the ground rail 221, the cylinder of the translation electric push rod 223 is hinged to one of the connecting plates 227, and the driving end of the translation electric push rod 223 is hinged to the bottom surface of the translation platform 222, so that the translation electric push rod 223 is not easy to get stuck when driving the translation platform 222 to move, and the translation platform 222 moves more smoothly.

[0042] In this embodiment, the rotating mechanism 210 is disposed above the translation platform 222, so that the translation mechanism 220 can drive the rotating mechanism 210 to translate, thereby realizing the combined translation and rotation adjustment of the seat 100. In addition, in other embodiments, the ground rail 221 can also be disposed above the rotating mechanism 210, so that the translation platform 222 slides above the rotating mechanism 210.

[0043] Reference Figure 2 and Figure 4The rotating mechanism 210 includes a lower ring seat 211, an upper ring seat 212, an inner gear ring 213, a driving gear 214 and a driving motor. The lower ring seat 211 and the upper ring seat 212 are both annular components with flanges on the outer circumference. The lower ring seat 211 is fixedly arranged above the translation platform 222, the upper ring seat 212 is arranged above the lower ring seat 211, and the upper ring seat 212 is inserted into the inner ring of the lower ring seat 211. The inner gear ring 213 is coaxially fixed to the inner ring of the upper ring seat 212, and the driving motor is connected to the driving gear 214 and the driving gear 214 is meshed with the inner gear ring 213. The housing of the driving motor is fixed to the lower ring seat 211 or to the translation platform 222. When the driving motor drives the driving gear 214 to rotate, it can drive the inner gear ring 213 to rotate, thereby driving the upper ring seat 212 to rotate relative to the lower ring seat 211, so as to drive the seat 100 to rotate.

[0044] A roller 215 is disposed between the upper ring seat 212 and the lower ring seat 211 to reduce friction when the upper ring seat 212 and the lower ring seat 211 rotate relative to each other.

[0045] Reference Figure 2 and Figure 5 In this embodiment, the lifting mechanism 230 is disposed above the rotating mechanism 210, and the rotating mechanism 210 can drive the lifting mechanism 230 to rotate when rotating. In addition, in other embodiments, the lifting mechanism 230 can also be disposed between the rotating mechanism 210 and the translation mechanism 220.

[0046] In this embodiment, the lifting mechanism 230 includes a lifting platform and a lifting drive 234. Among them, there are at least three lifting platforms stacked up and down, and among the three adjacent lifting platforms, the opposite ends of the lifting platform located in the middle are respectively connected to the lifting platform located below and the lifting platform located above, that is, the three adjacent lifting platforms are connected in a Z shape. The lifting drive 234 is arranged between two adjacent lifting platforms, and two lifting drives 234 are arranged between the three adjacent lifting platforms. The two lifting platforms in the middle and above are driven to rotate by two groups of lifting drives 234 between at least three adjacent lifting mechanisms 230, so that the lifting mechanism 230 can be extended and retracted in the vertical direction to drive the upper seat 100 to rise and fall. At the same time, the inclination degree of the uppermost lifting platform can be adjusted by adjusting the rotation angle of each lifting platform, thereby realizing the adjustment of the inclination angle of the seat 100.

[0047] Specifically, in this embodiment, three lifting platforms are provided, and the three lifting platforms are defined as a first lifting platform 231, a second lifting platform 232 and a third lifting platform 233 from bottom to top.

[0048] Reference Figure 5 and Figure 6A first rotating connecting plate 2311 is fixedly provided on the upper side of the rear end of the first lifting platform 231, and a first rotating connecting groove 2321 is opened on the lower side of the rear end of the second lifting platform 232. The first rotating connecting plate 2311 is inserted into the first rotating connecting groove 2321 and is pivotally connected to the first rotating connecting groove 2321, so that the second lifting platform 232 can rotate around the rear end of the first lifting platform 231.

[0049] A second rotating connecting groove 2322 is provided on the upper side of the front end of the second lifting platform 232, and a second rotating connecting plate 2331 is fixedly connected to the lower side of the front end of the third lifting platform 233. The second rotating connecting plate 2331 is inserted into the second rotating connecting groove 2322 and is pivotally connected to the second rotating connecting groove 2322, so that the third lifting platform 233 can rotate around the front end of the second lifting platform.

[0050] In addition, in other embodiments, the first rotating connecting plate 2311 can also be set on the second lifting platform 232, and the corresponding first rotating connecting groove 2321 is set on the first lifting platform 231; in other embodiments, the second rotating connecting plate 2331 can also be set on the second lifting platform 232, and the corresponding second rotating connecting groove 2322 is set on the third lifting platform 233.

[0051] In other embodiments, the positions of the corresponding rotating connecting plates and rotating connecting grooves may also be changed so that the second lifting platform 232 rotates around the front end of the first lifting platform 231 and the third lifting platform 233 rotates around the rear end of the second lifting platform 232 .

[0052] Reference Figures 5 to 7 The lifting drive member 234 includes a lifting electric push rod 2341 and a rotating support plate 2342. In two adjacent lifting platforms, the cylinder of the lifting electric push rod 2341 is hinged to a lifting platform located below, and the driving end of the lifting electric push rod 2341 is hinged to the rotating support plate 2342. One end of the rotating support plate 2342 is slidably abutted against the upper side of the lifting platform located below, and the end of the rotating support plate 2342 away from the lifting platform located below is rotatably connected to a lifting platform located above.

[0053] Specifically in this embodiment, in the lifting drive member 234 between the first lifting platform 231 and the second lifting platform 232, the cylinder of the lifting electric push rod 2341 is hinged to the rear end of the first lifting platform 231, and the driving end of the lifting electric push rod 2341 extends toward the front end of the first lifting platform 231 and is hinged to the lower end of the rotating support plate 2342. The lower end of the rotating support plate 2342 abuts against the upper side of the first lifting platform 231, and the upper end of the rotating support plate 2342 is rotatably connected to the lower side of the second lifting platform 232 through a horizontally arranged rotating shaft. Initially, the second lifting platform 232 is parallel to the first lifting platform 231, and the rotating support plate 2342 is tilted between the first lifting platform 231 and the second lifting platform 232; when the lifting electric push rod 2341 is extended and retracted, it can pull the rotating support plate 2342 to rotate around the second lifting platform 232. At the same time, the lower end of the rotating support plate 2342 moves along the upper side of the first lifting platform 231 to change the inclination angle of the rotating support plate 2342, so that the rotating support plate 2342 drives the second lifting platform 232 to rotate around the rear end of the first lifting platform 231.

[0054] In the lifting drive member 234 between the second lifting platform 232 and the third lifting platform 233, the cylinder of the lifting electric push rod 2341 is hinged to the rear end of the second lifting platform 232, and the driving end of the lifting electric push rod 2341 is hinged to the lower end of the rotating support plate 2342. The lower end of the rotating support plate 2342 abuts against the upper part of the second lifting platform 232, and the upper end of the rotating support plate 2342 is rotatably connected to the lower part of the third lifting platform 233 through a horizontally arranged rotating shaft. Initially, the third lifting platform 233 is parallel to the second lifting platform 232, and the rotating support plate 2342 is tilted between the second lifting platform 232 and the third lifting platform 233; when the lifting electric push rod 2341 is extended and retracted, it can pull the rotating support plate 2342 to rotate around the third lifting platform 233, and at the same time, the lower end of the rotating support plate 2342 moves along the upper side of the second lifting platform 232 to change the inclination angle of the rotating support plate 2342, driving the third lifting platform 233 to rotate around the front end of the second lifting platform 232.

[0055] Thus, when the height of the lifting mechanism 230 needs to be increased, the lifting drive 234 between the first lifting platform 231 and the second lifting platform 232 drives the second lifting platform 232 to rotate around the rear end of the first lifting platform 231 to a set angle, and at the same time, the lifting drive 234 between the second lifting platform 232 and the third lifting platform 233 drives the third lifting platform 233 to rotate around the front end of the second lifting platform 232 to a set angle, so that the third lifting platform 233 drives the seat 100 to rise and fall vertically without changing the inclination angle. In addition, in this embodiment, the second lifting platform 232 or the third lifting platform 233 can be rotated alone to adjust the front and rear inclination angles of the seat 100, further meeting the different sitting posture requirements of users.

[0056] In addition, in other embodiments, the number of lifts may also be other values ​​greater than three, and may be specifically set according to the required lifting height of the seat 100 during actual operation.

[0057] In two adjacent lifting platforms, the lower end of the rotating support plate 2342 (i.e., the end close to the lower lifting platform) is rotatably connected to the support roller 2343, and the support roller 2343 rolls and abuts against the upper side of the lower lifting platform. In this embodiment, in the lifting drive 234 between the first lifting platform 231 and the second lifting platform 232, the support roller 2343 of the rotating support plate 2342 rolls and abuts against the upper side of the first lifting platform 231; in the lifting drive 234 between the second lifting platform 232 and the third lifting platform 233, the support roller 2343 of the rotating support plate 2342 abuts against the upper side of the second lifting platform 232. As a result, the sliding friction between the rotating support plate 2342 and the lifting platform is converted into rolling friction through the support roller 2343, thereby reducing the friction when the rotating support plate 2342 slides relative to the lifting platform.

[0058] A cavity 235 is opened in the middle of the lifting platform, so that the rotating support plate 2342 and the lifting electric push rod 2341 in each lifting drive component 234 can be at least partially accommodated in the cavity 235, thereby reducing the overall space occupied by the lifting mechanism 230, making its structure more compact and reasonable, and the lifting drive component 234 is not easy to interfere with the lifting platform.

[0059] In addition, in other embodiments, the lifting mechanism 230 may also adopt other suitable vertical lifting mechanisms 230. For example, in one embodiment, the lifting mechanism 230 may include a linear drive member and a plate-like component, the seat 100 is mounted on the plate-like component, and the linear drive member is connected to the plate-like component and drives the plate-like component to move vertically.

[0060] Reference Figure 1 and Figure 2 In this embodiment, the foot pad assembly 400 is connected to the first lifting platform 231 of the lifting mechanism 230, so that when the foot pad assembly 400 can rotate with the rotating mechanism 210, the foot pad assembly 400 will not be lifted or lowered with the lifting mechanism 230, so that when the lifting mechanism 230 is adjusted, the distance between the foot pad assembly 400 and the seat 100 can be adjusted. In addition, in other embodiments, the foot pad assembly 400 can also be connected to the upper ring seat 212 of the rotating mechanism 210.

[0061] Reference Figure 2 and Figure 8In this embodiment, the base assembly 200 further includes a foot pad connection seat 240, which is fixedly connected to the front end of the first lifting platform 231 of the lifting mechanism 230. The foot pad assembly 400 includes a pedal 420, a mounting frame 410, a pedal driving member 430 and a mounting frame driving member 440. The mounting frame 410 is rotatably connected to the foot pad connection seat 240, the mounting frame driving member 440 is connected between the foot pad connection seat 240 and the mounting frame 410, and the mounting frame driving member 440 is used to drive the mounting frame 410 to rotate in a vertical plane relative to the base assembly 200. The pedal 420 is rotatably connected to the mounting frame 410, and the pedal driving member 430 is connected between the mounting frame 410 and the pedal 420 and is used to drive the pedal 420 to rotate in a vertical plane relative to the mounting frame 410.

[0062] The mounting frame 410 is driven by the mounting frame driving member 440 to rotate in the vertical plane relative to the base assembly 200, and the pedal 420 can be rotated relative to the mounting frame 410 under the drive of the pedal driving member 430, thereby increasing the adjustment range of the pedal 420 through two-stage rotation adjustment. At the same time, through the combination of the rotation of the mounting frame 410 and the rotation of the pedal 420 (such as the mounting frame 410 rotates forward to set an angle, and the pedal 420 rotates reversely to set an angle), the pedal 420 can be moved forward and backward and vertically raised and lowered without changing the inclination angle of the pedal 420, thereby adjusting the front and rear, up and down positions of the pedal 420, and further, when the user is working in a standing or sitting position, the pedal 420 can be adapted to the user's feet, which is convenient for the user to use.

[0063] Specifically, the mounting frame driving member 440 includes a first foot pad electric push rod, the cylinder of which is hinged to the foot pad connecting seat 240, a first hinge seat 411 is protrudingly provided below the mounting frame 410, and a driving end of the first foot pad electric push rod is hinged to the hinge seat.

[0064] The foot pad connection seat 240 is provided with a rotation avoidance groove 241, and the rotation avoidance groove 241 is arranged above the hinge point between the first foot pad electric push rod and the foot pad connection seat 240. Therefore, when the first foot pad electric push rod is extended, one end of the first foot pad electric push rod hinged to the foot pad connection seat 240 is suitable for rotating into the rotation avoidance groove 241, so that the first foot pad electric push rod can drive the mounting frame 410 to rotate upward around the foot pad connection seat 240. When the first foot pad electric push rod stops extending and retracting, the degree of freedom of the mechanism formed by the first foot pad electric push rod, the mounting frame 410 and the foot pad connection seat 240 is zero, that is, at this time, the mounting frame 410 will not rotate relative to the base assembly 200, so as to stably support the human foot.

[0065] Reference Figure 2 , Figure 8 and Fig. 9The mounting frame 410 is a C-shaped member, and the pedal 420 is installed in the C-shaped opening of the mounting frame 410. The mounting frame 410 has support shafts 412 protruding into the mounting frame 410 on opposite sides thereof, and the pedal 420 is rotatably matched with the support drawers on opposite sides thereof to support the pedal 420 on the mounting frame 410 and enable the pedal 420 to rotate relative to the mounting frame 410.

[0066] In this embodiment, the pedal driving member 430 includes a second foot pad electric push rod, a second hinge seat 413 is fixedly provided on the lower side of the mounting frame 410, a third hinge seat 421 is fixedly provided below the pedal 420, the cylinder of the second foot pad electric push rod is hinged to the second hinge seat 413, and the driving end of the second foot pad electric push rod is hinged to the third hinge seat 421. Therefore, when the second foot pad electric push rod is extended, it drives the pedal 420 to rotate around the support shaft 412, and at this time, the front end of the pedal 420 rotates upward; when the second foot pad electric push rod is retracted, the front end of the pedal 420 rotates downward; when the second foot pad electric push rod stops extending and retracting, the mechanism formed by the second foot pad electric push rod, the pedal 420 and the mounting frame 410 has zero degree of freedom, that is, at this time, the pedal 420 will not rotate relative to the mounting frame 410, so that the pedal 420 can stably support the user's foot.

[0067] When the pedal 420 needs to be adjusted so that the pedal 420 rotates upward, the first foot pad electric push rod is controlled to extend so that the front end of the mounting frame 410 rotates upward, thereby driving the pedal 420 to rotate upward; when the pedal 420 needs to be adjusted so that the pedal 420 rotates downward, the second foot pad electric push rod is controlled to retract so that the front end of the pedal 420 rotates downward relative to the mounting plate. When the pedal 420 needs to be moved forward or moved upward, the first foot pad electric push rod is controlled to extend so that the front end of the mounting frame 410 rotates upward, and the second foot pad electric push rod is controlled to retract so that the front end of the pedal 420 rotates downward by the same angle, thereby realizing the forward and upward movement of the pedal 420 without changing the angle of the pedal 420; conversely, the pedal 420 can be moved backward and downward by controlling the first foot pad electric push rod to retract and the second foot pad electric push rod to extend.

[0068] In this embodiment, the pedal 420 is a rectangular plate with a plurality of hollow grids formed thereon to reduce the weight and consumables of the pedal 420 while maintaining the structural strength of the pedal 420 , and to enhance the friction between the sole of the user's foot and the pedal 420 to prevent the foot from slipping on the pedal 420 .

[0069] The foot mat assembly 400 further includes a foot support rod 450, which is an L-shaped rod-shaped member, one end of which is connected to the mounting frame 410, and the other end of which extends forward to the front end of the pedal 420 and then bends horizontally toward the middle. The foot support rod 450 can be used as an extension of the pedal 420. When the pedal 420 cannot support the user's foot, the user can step on the part of the foot support rod 450 that is bent toward the middle and supported by the foot support rod 450.

[0070] Among them, the upper side of the front end of the mounting frame 410 is fixedly connected with a first fan-shaped connecting portion 414, and the first fan-shaped connecting portion 414 is arranged vertically. The rear end of the foot support rod 450 is connected with a second fan-shaped connecting portion 460, and the second fan-shaped connecting portion 460 is arranged parallel to and opposite to the first fan-shaped connecting portion 414. The second fan-shaped connecting portion 460 is rotatably connected to the first fan-shaped connecting portion 414. The first fan-shaped connecting portion 414 is provided with a plurality of first positioning pin holes 415 arranged along the circumferential direction, and the second fan-shaped connecting portion 460 is provided with at least one first connecting hole 461, and as the second fan-shaped connecting portion 460 rotates, the first connecting hole 461 can be aligned with the plurality of first top pin holes in sequence. The first positioning pin hole 415 and the first connecting hole 461 are both provided with a first positioning pin or a first positioning bolt, so that the second fan-shaped connecting part 460 can be rotated relative to the first fan-shaped connecting part 414 and locked by the first positioning pin or the first positioning bolt, thereby realizing the inclination adjustment of the foot support rod 450 in the vertical direction to meet the user's usage requirements.

[0071] Further, refer to Figures 8 to 10, a positioning sleeve 470 is provided on the outer sleeve of the rear end of the foot support rod 450, and the positioning sleeve 470 is fixed to the second fan-shaped connecting portion 460. The foot support rod 450 is rotatably matched with the positioning sleeve 470. Among them, a first limiting convex ring 451 is provided at the rear end of the foot support rod 450, and a second limiting convex ring 471 is provided at the front end of the positioning sleeve 470. The first limiting convex ring 451 and the second limiting convex ring 471 are arranged in parallel and opposite to each other. A second connecting hole 452 is provided on the first limiting convex ring 451, and a plurality of second positioning pin holes 472 are arranged circumferentially on the second limiting convex ring 471. When the foot support rod 450 rotates relative to the positioning sleeve 470, the second connecting hole 452 can be driven to rotate and align with the plurality of second positioning pin holes 472 in sequence. The second positioning pin hole 472 and the second connecting hole 452 are simultaneously penetrated with a second positioning pin or a second positioning bolt to lock the foot support rod 450 and the positioning sleeve 470. In this way, the foot support rod 450 can be rotated and adjusted so that the portion of the foot support rod 450 that is bent toward the middle rotates outward, so as to facilitate the user to enter the seat 100; then, the foot support rod 450 is rotated in the opposite direction so that the portion of the foot support rod 450 that is bent toward the middle rotates inward, and the foot support rod 450 is locked by means of the second positioning pin, the second positioning pin hole 472 and the second connecting hole 452, so that the user can step on the foot support rod 450 more stably.

[0072] When the user steps on the foot support rod 450, the front end of the pedal 420 can be driven to rotate downward, and the position of the pedal 420 can be adjusted front and back and up and down at the same time, so that the pedal 420 can support the user on the back of the user's calf, making the user's foot stepping more stably.

[0073] Reference Figure 2 In this embodiment, the operating armrest 300 includes a left armrest portion 310, a right armrest portion 320 and a connecting frame 330. The left armrest portion 310 and the right armrest portion 320 are respectively arranged on opposite sides of the seat 100, and the connecting frame 330 is arranged on the back of the seat 100 and connected to the left armrest portion 310 and the right armrest portion 320.

[0074] An armrest lifting assembly 340 for driving the armrest 300 to rise and fall is connected between the connecting frame 330 and the base assembly 200 . The armrest lifting assembly 340 drives the connecting frame 330 to rise and fall, thereby driving the left armrest portion 310 and the right armrest portion 320 to rise and fall synchronously.

[0075] Reference Figure 2 and Fig.11, wherein the handrail lifting assembly 340 includes a handrail electric push rod 341 and a guide rod 342. The lower end of the guide rod 342 is fixedly connected to the top of the third lifting platform 233 of the lifting mechanism 230, and a guide hole is provided on the connecting frame 330. The guide rod 342 passes through the guide hole and the connecting frame 330 can slide relative to the guide rod 342. The cylinder body of the handrail electric push rod 341 is hinged on the top of the third lifting platform 233 of the lifting mechanism 230, and the driving end of the handrail electric push rod 341 is hinged to the connecting frame 330, thereby making the handrail electric push rod 341 strictly parallel to the direction of the guide rod 342 when extending and retracting, so that the handrail electric push rod 341 can stably push the connecting frame 330 to lift and lower.

[0076] The upper end of the guide rod 342 is tilted upward in the backward direction, so that there is a certain inclination angle between the lifting direction of the connecting frame 330 and the vertical plane, so that the connecting frame 330 is not easy to interfere with the tilted backrest of the seat 100 when moving.

[0077] Reference Figure 2 and Fig.11 In this embodiment, a telescopic component is connected between the connecting frame 330 and the left armrest portion 310 and between the connecting frame 330 and the right armrest portion 320. The telescopic component is inclined relative to the horizontal plane and is used to drive the left armrest portion 310 and the right armrest portion 320 to translate.

[0078] Combination Fig.12 , wherein the telescopic assembly connecting the connecting frame 330 and the left armrest 310 is defined as the left telescopic assembly 350, and the telescopic assembly connecting the connecting frame 330 and the right armrest 320 is defined as the right telescopic assembly 360. The left telescopic assembly 350 includes a telescopic electric push rod 351 and a guide rod 352. The opposite ends of the telescopic electric push rod 351 are respectively hinged to the left armrest 310 and the connecting frame 330. The guide rod 352 is tilted upward in the direction toward the front side. The rear end of the guide rod 352 is connected to the mounting frame. The front end of the guide rod 352 passes through the left armrest 310 and cooperates with the left armrest 310. When the telescopic electric push rod 351 is extended, the left armrest 310 is driven to extend obliquely toward the front and upward. The structure of the right telescopic assembly 360 is exactly the same as that of the left telescopic assembly 350. The only difference is that the right telescopic assembly 360 is connected to the right armrest 320, which will not be repeated here.

[0079] Thus, by using the tilted telescopic assembly and the armrest lifting assembly 340, when adjusting the height of the operating armrest 300, the lifting of the connecting frame 330 will not interfere with the tilted chair back, and when the connecting frame 330 rises, it drives the left armrest 310 and the right armrest 320 to move backward, and when the left armrest 310 and the right armrest 320 are driven to move up and down by the telescopic assembly alone, the left armrest 310 and the right armrest 320 can be driven to move forward, thereby offsetting the influence of the tilted lifting of the armrest lifting assembly 340 on the horizontal position of the operating armrest 300. This arrangement can greatly reduce the space occupied by the operating table 1000 after the operating armrest 300 is retracted and lowered, and the overall structure of the operating table 1000 is more compact and reasonable.

[0080] In addition, in other embodiments, the telescopic assembly may also be provided at only one of the left armrest portion 310 and the right armrest portion 320 .

[0082] Specifically, in this embodiment, the swing mechanism 370 includes a swing electric push rod 371, a swing connecting rod 372 and a swing shaft 373. The swing shaft 373 is rotatably connected to the connecting frame 330 horizontally, the guide rod 352 is fixed to the swing shaft 373, and the cylinder body of the telescopic electric push rod 351 is hinged to the swing shaft 373. One end of the swing connecting rod 372 is fixedly connected to the swing shaft 373, and the other end of the swing connecting rod 372 is hinged to the driving end of the swing electric push rod 371. The cylinder body of the swing electric push rod 371 is hinged to the connecting frame 330. When the swing electric push rod 371 is extended, it drives the swing shaft 373 to rotate through the swing connecting rod 372, thereby driving the telescopic assembly to swing inward in the vertical direction, so as to drive the left armrest portion 310 and / or the right armrest portion 320 to rotate in the vertical direction.

[0083] Reference Fig.11 and Fig.12 The left armrest 310 includes a left base 311 and a left operating panel 312. The left telescopic assembly 350 is connected to the left base 311, and the left operating panel 312 is arranged above the left base 311. The left operating panel 312 may be provided with operating components such as buttons, rockers and screens for users to operate mechanical equipment. The left operating panel 312 is connected to the left base 311 through a linear driving member, so that the left operating panel 312 can be driven to slide relative to the left base 311 in the front-rear direction.

[0084] Furthermore, the right armrest portion 320 includes a right base 321 and a right operating panel 322 . The right telescopic assembly 360 is connected to the right base 321 . The right operating panel 322 is driven by a linear driving member to slide forward and backward along the top of the right base 321 .

[0085] Reference Figure 1 and Figure 2 The seat 100 is arranged above the lifting mechanism 230. A buffer mechanism 500 is connected between the seat 100 and the third lifting platform 233 of the lifting mechanism 230, and the buffer mechanism 500 is used to reduce the vibration of the seat 100, thereby improving the user experience.

[0086] Preferably, the buffer mechanism 500 adopts a gas spring or a hydraulic spring, so that the buffer mechanism 500 can further drive the seat 100 to rise and fall, thereby increasing the adjustment range of the seat 100.

[0087] In this embodiment, all the electric push rods are controlled by a controller, which can be electrically connected to the buttons on the operating armrest 300, so that the operating platform 1000 can be controlled through the operating armrest 300 to perform translation, rotation, lifting, lifting of the operating armrest 300, telescopic translation of the operating armrest 300, rotation of the foot pad assembly 400 and other posture changes, so that the user can adjust the operating platform 1000 in real time to adapt to sitting and standing operations.

[0088] In other embodiments, a pneumatic or hydraulic system may be used to drive the operating platform 1000 to change its posture, that is, in other embodiments, a pneumatic cylinder or a hydraulic cylinder may be used to replace the electric push rod in this embodiment.
