DETAILED DESCRIPTION

[0039] The present application will be further described below with reference to the drawings.

[0040] The present embodiment discloses an operation table 1000, which is used in the cab or control room of a mechanical device, referring to Figure 1, the operating platform 1000 comprises a seat 100, a base assembly 200, an operating armrest 300 and a foot pad assembly 400. The seat 100 is used for a user to sit in, the base assembly 200 is arranged below the seat 100 and is used 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 circumferential side of the seat 100; buttons and joysticks are arranged on the operating armrest 300 and are used for the user to operate the mechanical equipment.

[0041] The operating armrest 300 can be lifted 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 a human foot to be placed on. The foot pad assembly 400 is adapted to rotate relative to the base assembly 200 to adjust the inclination angle.

[0042] 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 armrest 300 on the circumferential side of the seat 100, and drive the seat 100 to rotate, move horizontally and lift vertically through the base assembly 200, so as to adjust the posture of the seat 100 and meet the sitting position requirements of different users. Meanwhile, 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 case that the human foot stretches forward and the rear foot plate inclines upward.

[0043] When the user needs to stand to obtain a better work field of view for a long time, 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, the foot pad assembly 400 is rotated relative to the base assembly 200 to adjust the supporting angle of the user, the base assembly 200 drives the operating armrest 300 to lift, and the operating armrest 300 is lifted and horizontally slid relative to the seat 100, so that the operating armrest 300 extends to both sides of the standing human body, and thus the user can operate the mechanical equipment in a standing position.

[0044] Therefore, the operating platform 1000 can not only adjust the posture of the seat 100 to meet the sitting position requirements of different users, but also can adapt to the requirement of the user working in a standing position, and improve the comfort of the user during use.

[0045] Referring to Figure 1 and Figure 2 , the base assembly 200 comprises a rotating mechanism 210, a translating mechanism 220 and a lifting mechanism 230 connected to each other. The rotating mechanism 210 is used to drive the seat 100 to rotate circumferentially, the translating 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 lift vertically.

[0046] In the embodiment, the translation mechanism 220 includes a ground rail 221, a translation table 222, and a translation electric push rod 223. The translation ground rail 221 is fixedly arranged in the driver's cabin or the control room in the front-rear direction. Here, the front refers to the direction in which the seat 100 faces the user, and the rear refers to the direction in which the seat 100 faces away from the user. The translation table 222 is slidably connected to the ground rail 221 in the front-rear direction, and the translation electric push rod 223 is connected between the ground rail 221 and the translation table 222 to drive the translation table 222 to slide on the ground rail 221.

[0047] In the embodiment, the translation mechanism 220 includes a ground rail 221, a translation table 222, and a translation electric push rod 223. The translation ground rail 221 is fixedly arranged in the driver's cabin or the control room in the front-rear direction. Here, the front refers to the direction in which the seat 100 faces the user, and the rear refers to the direction in which the seat 100 faces away from the user. The translation table 222 is slidably connected to the ground rail 221 in the front-rear direction, and the translation electric push rod 223 is connected between the ground rail 221 and the translation table 222 to drive the translation table 222 to slide on the ground rail 221.

[0048] Referring to 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 into one body to enhance the structural strength. In the embodiment, the translation electric push rod 223 is arranged parallel to the ground rail 221, the cylinder body 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 lower bottom surface of the translation table 222, so that the translation electric push rod 223 is not easy to be stuck when driving the translation table 222 to move, and the translation table 222 moves more smoothly.

[0049] In the embodiment, the rotation mechanism 210 is arranged above the translation table 222, so that the translation mechanism 220 can drive the rotation mechanism 210 to translate, thereby realizing combined adjustment of the translation and rotation of the seat 100. In other embodiments, the ground rail 221 can also be arranged above the rotation mechanism 210, so that the translation table 222 slides above the rotation mechanism 210.

[0050] Referring to Figure 2 and Figure 4The rotating mechanism 210 comprises a lower ring seat 211, an upper ring seat 212, an inner ring gear 213, a driving gear 214 and a driving motor. The lower ring seat 211 and the upper ring seat 212 are both annular members provided with flanges on the outer circumferential side. The lower ring seat 211 is fixedly arranged above the translation table 222, and the upper ring seat 212 is arranged above the lower ring seat 211 and inserted into the inner ring of the lower ring seat 211. The inner ring gear 213 is coaxially fixed in the inner ring of the upper ring seat 212, and the driving motor is connected to the driving gear 214 which is engaged with the inner ring gear 213. The housing of the driving motor is fixed to the lower ring seat 211 or the translation table 222. When the driving motor drives the driving gear 214 to rotate, the inner ring gear 213 is driven to rotate, thereby driving the upper ring seat 212 to rotate relative to the lower ring seat 211 to drive the seat 100 to rotate.

[0051] The upper ring seat 212 and the lower ring seat 211 are provided with rollers 215 therebetween to reduce the friction when the upper ring seat 212 and the lower ring seat 211 rotate relative to each other.

[0052] With reference to Figure 2 and Figure 5 In this embodiment, the lifting mechanism 230 is arranged above the rotating mechanism 210 and can be driven to rotate by the rotating mechanism 210. In other embodiments, the lifting mechanism 230 can also be arranged between the rotating mechanism 210 and the translation mechanism 220.

[0053] In this embodiment, the lifting mechanism 230 comprises a lifting table and a lifting driving member 234. At least three lifting tables are arranged in a stack from bottom to top, and the opposite ends of the lifting table in the middle are rotationally connected to the lifting table below and the lifting table above, i.e. the three adjacent lifting tables are connected in a Z shape. The lifting driving member 234 is arranged between two adjacent lifting tables, and two lifting driving members 234 are arranged between the three adjacent lifting tables. The two lifting tables above and below are driven to rotate by the two groups of lifting driving members 234 between the at least three adjacent lifting mechanisms 230, so that the lifting mechanism 230 is vertically telescopic to drive the seat 100 above to lift, and the inclination of the uppermost lifting table can also be adjusted by adjusting the rotation angle of each lifting table, thereby adjusting the inclination angle of the seat 100.

[0054] Specifically, in this embodiment, the lifting table is arranged in three, and the three lifting tables are defined as a first lifting table 231, a second lifting table 232 and a third lifting table 233 from bottom to top.

[0055] With reference to Figure 5 and Figure 6The rear end upper side of the first lifting platform 231 is fixedly provided with a first rotating connecting plate 2311, and the rear end lower side of the second lifting platform 232 is provided with a first rotating connecting groove 2321, the first rotating connecting plate 2311 is inserted into the first rotating connecting groove 2321 and connected with the first rotating connecting groove 2321 through a pivot, so that the second lifting platform 232 can rotate around the rear end of the first lifting platform 231.

[0056] The front end upper side of the second lifting platform 232 is provided with a second rotating connecting groove 2322, and the front end lower side of the third lifting platform 233 is fixedly connected with a second rotating connecting plate 2331, the second rotating connecting plate 2331 is inserted into the second rotating connecting groove 2322 and connected with the second rotating connecting groove 2322 through a pivot, so that the third lifting platform 233 can rotate around the front end of the second lifting platform 232.

[0057] In addition, in other embodiments, the first rotating connecting plate 2311 can also be arranged on the second lifting platform 232, and the corresponding first rotating connecting groove 2321 is arranged on the first lifting platform 231; in other embodiments, the second rotating connecting plate 2331 can also be arranged on the second lifting platform 232, and the corresponding second rotating connecting groove 2322 is arranged on the third lifting platform 233.

[0058] In other embodiments, the positions of the corresponding rotating connecting plate and rotating connecting groove can 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.

[0059] Referring to Figure 5 to Figure 7 The lifting driving member 234 comprises a lifting electric push rod 2341 and a rotating support plate 2342, among the adjacent two lifting platforms, the cylinder body of the lifting electric push rod 2341 is hinged to the lower one of the lifting platforms, 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 to the upper side of the lower lifting platform, and the end of the rotating support plate 2342 away from the lower lifting platform is rotatably connected to the upper one of the lifting platforms.

[0060] Specifically, in the lifting driving 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 towards 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 obliquely arranged between the first lifting platform 231 and the second lifting platform 232; when the lifting electric push rod 2341 is extended or retracted, the rotating support plate 2342 is pulled to rotate around the second lifting platform 232, and 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.

[0061] In the lifting driving 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 side of the second lifting platform 232, and the upper end of the rotating support plate 2342 is rotatably connected to the lower side 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 obliquely arranged between the second lifting platform 232 and the third lifting platform 233; when the lifting electric push rod 2341 is extended or retracted, the rotating support plate 2342 is pulled 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, so that the third lifting platform 233 is driven to rotate around the front end of the second lifting platform 232.

[0062] Therefore, when it is necessary to increase the height of the lifting mechanism 230, the lifting driving member 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 by a set angle, and at the same time, the lifting driving member 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 by a set angle, so that the third lifting platform 233 drives the seat 100 to vertically lift without changing the inclination angle. In addition, in the present embodiment, the second lifting platform 232 can be rotated alone or the third lifting platform 233 can be rotated alone to adjust the front-rear inclination angle of the seat 100, further meeting the different sitting posture requirements of users.

[0063] In other embodiments, the number of lifting platforms can also be other numbers greater than three, which can be set according to the lifting height required by the seat 100 in actual operation.

[0064] The lower end of the rotating support plate 2342 (i.e. the end close to the lifting platform below) is rotatably connected with a support roller 2343, which rolls against the upper side of the lifting platform below. In this embodiment, the support roller 2343 of the rotating support plate 2342 rolls against the upper side of the first lifting platform 231 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 against the upper side of the second lifting platform 232 in the lifting drive 234 between the second lifting platform 232 and the third lifting platform 233. In this way, the sliding friction between the rotating support plate 2342 and the lifting platform is converted into rolling friction by the support roller 2343, reducing the friction when the rotating support plate 2342 slides relative to the lifting platform.

[0065] A cavity 235 is formed 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 234 can be at least partially accommodated in the cavity 235, thereby reducing the overall space occupied by the lifting mechanism 230, making the structure more compact and reasonable, and the lifting drive 234 is less likely to interfere with the lifting platform.

[0066] In addition, in other embodiments, the lifting mechanism 230 can also use other suitable vertical lifting mechanisms 230. For example, in one embodiment, the lifting mechanism 230 can include a linear drive and a plate-shaped member, the seat 100 is mounted on the plate-shaped member, and the linear drive is connected to the plate-shaped member and drives the plate-shaped member to move vertically.

[0067] Referring to 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 the foot pad assembly 400 can rotate with the rotating mechanism 210, and the foot pad assembly 400 will not be lifted with the lifting mechanism 230, so that the lifting mechanism 230 can adjust the distance between the foot pad assembly 400 and the seat 100. 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.

[0068] Referring to Figure 2 and Figure 8In the embodiment, the base assembly 200 further comprises a foot pad connecting seat 240 fixedly connected to the front end of the first lifting platform 231 of the lifting mechanism 230. The foot pad assembly 400 comprises a pedal 420, a mounting rack 410, a pedal driving member 430 and a mounting rack driving member 440. The mounting rack 410 is rotatably connected to the foot pad connecting seat 240, the mounting rack driving member 440 is connected between the foot pad connecting seat 240 and the mounting rack 410, and the mounting rack driving member 440 is used to drive the mounting rack 410 to rotate in the vertical plane relative to the base assembly 200. The pedal 420 is rotatably connected to the mounting rack 410, and the pedal driving member 430 is connected between the mounting rack 410 and the pedal 420 and is used to drive the pedal 420 to rotate in the vertical plane relative to the mounting rack 410.

[0069] The mounting rack 410 is driven by the mounting rack driving member 440 to rotate in the vertical plane relative to the base assembly 200, and the pedal 420 can rotate relative to the mounting rack 410 under the driving of the pedal driving member 430, so that the adjustment range of the pedal 420 is increased by two-stage rotation adjustment, and the combination of the rotation of the mounting rack 410 and the rotation of the pedal 420 (for example, the mounting rack 410 is positively rotated by a set angle, and then the pedal 420 is reversely rotated by a set angle) can realize the forward and backward movement and vertical lifting of the pedal 420 without changing the inclination angle of the pedal 420, so as to adjust the forward and backward and up and down positions of the pedal 420, and further adapt the pedal 420 to the user's feet when the user works in a standing or sitting position, thereby facilitating the user's use.

[0070] Specifically, the mounting rack driving member 440 comprises a first foot pad electric push rod. The cylinder body of the first foot pad electric push rod is hinged to the foot pad connecting seat 240, and the first hinged seat 411 is protruded below the mounting rack 410. The driving end of the first foot pad electric push rod is hinged to the hinged seat.

[0071] The foot pad connecting seat 240 is provided with a rotation avoiding groove 241 above the hinged point of the first foot pad electric push rod and the foot pad connecting seat 240. Thus, when the first foot pad electric push rod is elongated, one end of the first foot pad electric push rod hinged to the foot pad connecting seat 240 is adapted to rotate into the rotation avoiding groove 241, so that the first foot pad electric push rod can drive the mounting rack 410 to rotate upward around the foot pad connecting seat 240. When the first foot pad electric push rod stops elongating and contracting, the mechanism formed by the first foot pad electric push rod, the mounting rack 410 and the foot pad connecting seat 240 has zero degree of freedom, that is, the mounting rack 410 will not rotate relative to the base assembly 200 at this time, so as to stably support the human foot.

[0072] Referring to Figure 2 , Figure 8 and Figure 9The mounting frame 410 is a C-shaped member, and the pedal 420 is mounted in the C-shaped opening of the mounting frame 410. The opposite sides of the mounting frame 410 are each provided with a support shaft 412 protruding inwardly into the mounting frame 410, and the opposite sides of the pedal 420 are rotationally fitted on the support shafts 412 to support the pedal 420 on the mounting frame 410 and enable the pedal 420 to rotate relative to the mounting frame 410.

[0073] In this embodiment, the pedal driving member 430 comprises a second foot pad electric push rod, the lower side of the mounting frame 410 is fixedly provided with a second hinge seat 413, the lower side of the pedal 420 is fixedly provided with a third hinge seat 421, the cylinder body of the second foot pad electric push rod is hingedly connected to the second hinge seat 413, and the driving end of the second foot pad electric push rod is hingedly connected to the third hinge seat 421. Thus, when the second foot pad electric push rod is extended, the pedal 420 is driven to rotate around the support shaft 412, and at this time, the front end of the pedal 420 is upwardly rotated; when the second foot pad electric push rod is retracted, the front end of the pedal 420 is downwardly rotated; and when the second foot pad electric push rod is stopped from 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, i.e., at this time, the pedal 420 cannot rotate relative to the mounting frame 410, so that the pedal 420 can stably support the user's foot.

[0074] When it is needed to adjust the pedal 420 to be upwardly rotated, the first foot pad electric push rod is controlled to be extended to drive the mounting frame 410 to be upwardly rotated, thereby driving the pedal 420 to be upwardly rotated; when it is needed to adjust the pedal 420 to be downwardly rotated, the second foot pad electric push rod is controlled to be retracted to drive the front end of the pedal 420 to be downwardly rotated relative to the mounting plate. When it is needed to move the pedal 420 forward or upward, the first foot pad electric push rod is controlled to be extended to drive the mounting frame 410 to be upwardly rotated, and at the same time, the second foot pad electric push rod is controlled to be retracted to drive the front end of the pedal 420 to be downwardly rotated by the same angle, thereby enabling the pedal 420 to be moved forward and upward without changing the angle of the pedal 420; conversely, the first foot pad electric push rod is controlled to be retracted and the second foot pad electric push rod is controlled to be extended to enable the pedal 420 to be moved backward and downward.

[0075] In this embodiment, the pedal 420 is a rectangular plate, and a plurality of hollow grids are formed in the pedal 420 to reduce the weight and material consumption of the pedal 420 while maintaining the structural strength of the pedal 420, and to enhance the friction between the user's foot and the pedal 420 to avoid the foot from slipping on the pedal 420.

[0076] The foot pad assembly 400 further comprises a foot stepping support rod 450, which is an L-shaped rod member, one end of which is connected to the mounting frame 410, and the other end extends forward to the front end of the pedal 420 and then bends horizontally to the middle. The foot stepping support rod 450 can be used as an extension of the pedal 420. When the pedal 420 cannot support the user's feet, the user can step on the part of the foot stepping support rod 450 that bends to the middle to be supported by the foot stepping support rod 450.

[0077] The first fan-shaped connecting part 414 is fixedly connected to the upper side of the front end of the mounting frame 410 and is arranged vertically. The second fan-shaped connecting part 460 is connected to the rear end of the foot stepping support rod 450 and is arranged in parallel and opposite to the first fan-shaped connecting part 414. The second fan-shaped connecting part 460 is rotatably connected to the first fan-shaped connecting part 414. The first fan-shaped connecting part 414 is circumferentially arranged with a plurality of first positioning pin holes 415, and the second fan-shaped connecting part 460 is arranged with at least one first connecting hole 461, which can be aligned with the plurality of first positioning pin holes 415 in turn as the second fan-shaped connecting part 460 rotates. A first positioning pin or a first positioning bolt is simultaneously arranged in the first positioning pin hole 415 and the first connecting hole 461, 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, and the inclination angle of the foot stepping support rod 450 in the vertical direction can be adjusted to meet the user's needs.

[0078] Further, with reference to Figure 8 to Figure 10The rear end of the footrest support rod 450 is provided with a positioning sleeve 470 fixed to the second fan-shaped connecting part 460. The footrest support rod 450 is rotationally fitted in the positioning sleeve 470. The rear end of the footrest support rod 450 is provided with a first limiting convex ring 451, and the front end of the positioning sleeve 470 is provided with a second limiting convex ring 471. The first limiting convex ring 451 and the second limiting convex ring 471 are arranged in parallel and face each other. A second connecting hole 452 is formed in 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 footrest support rod 450 rotates relative to the positioning sleeve 470, the second connecting hole 452 can be rotated and aligned with the plurality of second positioning pin holes 472 in turn. A second positioning pin or a second positioning bolt is simultaneously arranged in the second positioning pin hole 472 and the second connecting hole 452 to lock the footrest support rod 450 and the positioning sleeve 470. Thus, the footrest support rod 450 can be rotationally adjusted so that the portion of the footrest support rod 450 bent towards the middle rotates outward to facilitate the user to enter the seat 100. Then, the footrest support rod 450 is reversely rotated so that the portion of the footrest support rod 450 bent towards the middle rotates inward, and the footrest support rod 450 is locked by the cooperation of the second positioning pin and the second positioning pin hole 472 and the second connecting hole 452 to make the user step on the footrest support rod 450 more stably.

[0079] When the user steps on the footrest 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 so that the pedal 420 can support the user's leg and make the user's foot step more stably.

[0080] Referring to Figure 2 In the embodiment, the operating armrest 300 includes a left armrest part 310, a right armrest part 320, and a connecting frame 330. The left armrest part 310 and the right armrest part 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 part 310 and the right armrest part 320.

[0081] The armrest lifting assembly 340 for driving the operating armrest 300 to lift is connected between the connecting frame 330 and the base assembly 200. The armrest lifting assembly 340 drives the connecting frame 330 to lift, thereby driving the left armrest part 310 and the right armrest part 320 to synchronously lift.

[0082] Referring to Figure 2 and Figure 11The handrail lifting assembly 340 comprises a handrail electric push rod 341 and a guide rod 342. The lower end of the guide rod 342 is fixedly connected to the upper side of the third lifting platform 233 of the lifting mechanism 230, and a guide hole is formed in 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 of the handrail electric push rod 341 is hingedly connected to the upper side of the third lifting platform 233 of the lifting mechanism 230, and the driving end of the handrail electric push rod 341 is hingedly connected to the connecting frame 330. Thus, when the handrail electric push rod 341 extends or retracts, it is strictly parallel to the direction of the guide rod 342, so that the handrail electric push rod 341 stably pushes the connecting frame 330 to lift.

[0083] The upper end of the guide rod 342 is inclined upward in the rear direction, so that the lifting direction of the connecting frame 330 has a certain inclination with the vertical plane, so that the connecting frame 330 is not easy to interfere with the inclined backrest of the seat 100 when moving.

[0084] Referring to Figure 2 and Figure 11 In this embodiment, a telescopic assembly is connected between the connecting frame 330 and the left handrail part 310 and between the connecting frame 330 and the right handrail part 320. The telescopic assembly is inclined relative to the horizontal plane and is used to drive the left handrail part 310 and the right handrail part 320 to translate.

[0085] In combination Figure 12 The telescopic assembly connected between the connecting frame 330 and the left handrail part 310 is defined as a left telescopic assembly 350, and the telescopic assembly connected between the connecting frame 330 and the right handrail part 320 is defined as a right telescopic assembly 360. The left telescopic assembly 350 comprises a telescopic electric push rod 351 and a guide rod 352. The opposite ends of the telescopic electric push rod 351 are hingedly connected to the left handrail part 310 and the connecting frame 330, respectively. The guide rod 352 is inclined upward in the front direction. The rear end of the guide rod 352 is connected to the mounting frame, and the front end of the guide rod 352 passes through the left handrail part 310 and is guided in cooperation with the left handrail part 310. When the telescopic electric push rod 351 extends, it drives the left handrail part 310 to extend obliquely toward the front and the upper side. The right telescopic assembly 360 is identical in structure to the left telescopic assembly 350, except that the right telescopic assembly 360 is connected to the right handrail part 320. Details are not described here.

[0086] Therefore, by the oblique arrangement of the telescopic assembly and the handrail lifting assembly 340, when adjusting the height of the operating handrail 300, the lifting of the connecting frame 330 does not interfere with the oblique chair back, and when the connecting frame 330 is lifted, the left and right handrail sections 310 and 320 are lifted and moved backward at the same time, and when the left and right handrail sections 310 and 320 are lifted by the telescopic assembly alone, the left and right handrail sections 310 and 320 are driven to move forward, thereby offsetting the influence of the oblique lifting of the handrail lifting assembly 340 on the horizontal position of the operating handrail 300. This arrangement can greatly reduce the space occupied by the operating platform 1000 after the operating handrail 300 is retracted and lowered, and the overall structure of the operating platform 1000 is more compact and reasonable.

[0087] In addition, in other embodiments, the telescopic assembly can also be arranged only at one of the left and right handrail sections 310 and 320.

[0088] Referring to Figure 12 , the connecting frame 330 is also provided with a swing mechanism 370, one swing mechanism 370 is arranged on each of the left and right sides of the connecting frame 330, and the swing mechanism 370 is used to drive the left and right handrail sections 310 and 320 to swing in the vertical plane to adjust the inclination angle.

[0089] Specifically, in the present 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 and horizontally connected to the connecting frame 330, the guide rod 352 is fixed to the swing shaft 373, and the cylinder 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 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 in the vertical direction to drive the left and / or right handrail sections 310 and 320 to rotate in the vertical direction.

[0090] Referring to Figure 11 and Figure 12 , the left handrail section 310 includes a left bottom platform 311 and a left operating panel 312, the left telescopic assembly 350 is connected to the left bottom platform 311, and the left operating panel 312 is arranged above the left bottom platform 311. The left operating panel 312 can be provided with operating components such as buttons, joysticks, and screens for the user to operate the mechanical equipment. The left operating panel 312 and the left bottom platform 311 are connected by a linear drive to drive the left operating panel 312 to slide relative to the left bottom platform 311 in the front-rear direction.

[0091] Further, the right armrest part 320 comprises a right bottom base 321 and a right operation panel 322, the right telescopic assembly 360 is connected to the right bottom base 321, and the right operation panel 322 is driven to slide forward and backward above the right bottom base 321 by a linear drive.

[0092] With reference to Figure 1 and Figure 2 , the seat 100 is arranged above the lifting mechanism 230. The seat 100 and the third lifting base 233 of the lifting mechanism 230 are connected by a buffer mechanism 500, which can reduce the vibration of the seat 100 and improve the user experience.

[0093] Preferably, the buffer mechanism 500 adopts a gas spring or a hydraulic spring, so that the seat 100 can be further driven to lift by the buffer mechanism 500, and the adjustment range of the seat 100 is improved.

[0094] In the embodiment, all the electric push rods are controlled by a controller, which can be electrically connected with the buttons on the operation armrest 300, so that the overall operation table 1000 can be controlled to change the posture by operating the operation armrest 300, such as translation, rotation, lifting, lifting of the operation armrest 300, telescopic translation of the operation armrest 300, rotation of the foot pad assembly 400, etc., so that the user can adjust the operation table 1000 in real time to adapt to the sitting and standing postures.

[0095] In other embodiments, a pneumatic or hydraulic system can also be used to drive the operation table 1000 to change the posture, that is, a pneumatic cylinder or a hydraulic cylinder can be used instead of the electric push rod in the embodiment.

[0096] The above description is only the preferred embodiment of the present application, so any equivalent changes or modifications made according to the structure, features and principles described in the patent application range of the present application are included in the patent application range of the present application.
