[0038] In the present application, the synchronous operation of both A and B means that in the time dimension, the motion states of both A and B remain consistent. Specifically, the start time, operation time, and stop time of both A and B are all the same, that is, they start synchronously, operate synchronously, and stop synchronously.

[0039] Embodiment

[0040] Refer to Figures 1-4 , in this embodiment, a lifting and adjusting device is proposed, which includes a first scissor lift mechanism 101, a second scissor lift mechanism 102, a linear motion device 200, and a carrier 300.

[0041] The linear motion device 200 includes a first driving part 210 and a second driving part 220 that operate synchronously. Both the first driving part 210 and the second driving part 220 are used to output linear motion.

[0042] The first driving part 210 is connected to the first scissor lift mechanism 101, where the first driving part 210 is used to drive the first scissor lift mechanism 101. The second driving part 220 is connected to the second scissor lift mechanism 102, where the second driving part 220 is used to drive the second scissor lift mechanism 102.

[0043] Both the first scissor lift mechanism 101 and the second scissor lift mechanism 102 are connected to the carrier 300, and the first scissor lift mechanism 101 and the second scissor lift mechanism 102 are used to drive the carrier 300 to move up and down.

[0044] When the linear motion device 200 is started, the first driving part 210 and the second driving part 220 operate synchronously, thereby driving the first scissor lift mechanism 101 and the second scissor lift mechanism 102 to move synchronously, and thus driving the carrier 300 to rise or fall. This lifting and adjusting device is equipped with the first scissor lift mechanism 101 and the second scissor lift mechanism 102, thereby effectively improving the load-bearing capacity of the device.

[0045] Such as Figure 3 AndFigure 4 As shown in Figure 4 , in this embodiment, the lifting and adjusting device further includes a base 400 and a sliding seat slidably disposed on the base 400. There are two sliding seats, which respectively correspond to the first scissor lift mechanism 101 and the second scissor lift mechanism 102. For the convenience of description, the sliding seat corresponding to the first scissor lift mechanism 101 is named the first sliding seat 411; the sliding seat corresponding to the second scissor lift mechanism 102 is named the second sliding seat 412. Among them, the first sliding seat 411 corresponds to the first driving part 210, and the second sliding seat 412 corresponds to the second driving part 220.

[0046] Both the first scissor lift mechanism 101 and the second scissor lift mechanism 102 include a first connecting rod 110 and a second connecting rod 120. In this embodiment, the structures of the first scissor lift mechanism 101 and the second scissor lift mechanism 102 can be the same, and among them, the first scissor lift mechanism 101 and the second scissor lift mechanism 102 can be arranged in mirror symmetry.

[0047] First scissor lift mechanism 101: One end of the first connecting rod 110 is rotatably connected to the base 400, and the other end is rotatably connected to its own second connecting rod 120; one end of the second connecting rod 120 is rotatably connected to the first sliding seat 411, and the other end is rotatably connected to the carrier seat 300. Second scissor lift mechanism 102: One end of the first connecting rod 110 is rotatably connected to the base 400, and the other end is rotatably connected to its own second connecting rod 120; one end of the second connecting rod 120 is rotatably connected to the second sliding seat 412, and the other end is rotatably connected to the carrier seat 300. A preset position is provided on the second connecting rod 120, and among them, the first connecting rod 110 is rotatably connected to the preset position of the corresponding second connecting rod 120. The preset position is located between the two ends of the second connecting rod 120. Specifically, the preset position can be located at the middle position of the second connecting rod 120.

[0048] The first driving part 210 is connected to the first sliding seat 411, and the second driving part 220 is connected to the second sliding seat 412. When the linear motion device 200 is started, under the action of the first driving part 210 and the second driving part 220, the first sliding seat 411 and the second sliding seat 412 run synchronously, thereby driving the second connecting rod 120 of the first scissor lift mechanism 101 and the second scissor lift mechanism 102 to rotate, and thus the lifting of the carrier seat 300 is realized.

[0049] In this embodiment, the first driving part 210 includes a first screw-nut mechanism, and the second driving part 220 includes a second screw-nut mechanism.

[0050] The first lead screw nut mechanism includes a first lead screw 211 and a first nut seat 212 that are threadedly connected, and the second lead screw nut mechanism includes a second lead screw 221 and a second nut seat 222 that are threadedly connected.

[0051] The first nut seat 212 is connected to the first sliding seat 411, and the second nut seat 222 is connected to the second sliding seat 412. Specifically, assembly through holes are provided on both the first sliding seat 411 and the second sliding seat 412. Among them, the first nut seat 212 is installed in the assembly through hole of the first sliding seat 411, and the second nut seat 222 is installed in the assembly through hole of the second sliding seat 412. The first nut seat 212 and the first sliding seat 411 can be fixedly connected by means such as bolt connection, and the second nut seat 222 installed in the second sliding seat 412 can be fixedly connected by means such as bolt connection.

[0052] Both the first lead screw 211 and the second lead screw 221 are rotatably connected to the base 400. Among them, the first lead screw 211 and the second lead screw 221 are coaxially arranged and are synchronously rotationally connected. The thread directions of the first lead screw 211 and the second lead screw 221 are opposite. When the linear motion device 200 is started, the first nut seat 212 and the second nut seat 222 will perform linear motion in opposite directions (towards each other or away from each other). Since the first sliding seat 411 is fixedly connected to the first nut seat 212, and the second sliding seat 412 is fixedly connected to the second nut seat 222, the first sliding seat 411 and the second sliding seat 412 will also perform linear motion in opposite directions, thus driving the second link 120 of both the first scissor lift mechanism 101 and the second scissor lift mechanism 102 to rotate, thereby realizing the lifting of the carrier 300.

[0053] In this embodiment, the linear motion device 200 further includes a transmission shaft 230. The two ends of the transmission shaft 230 are respectively synchronously rotationally connected to the first lead screw 211 and the second lead screw 221. The first lead screw 211, the transmission shaft 230, and the second lead screw 221 are connected in sequence, and the first lead screw 211, the transmission shaft 230, and the second lead screw 221 are coaxially arranged.

[0054] Furthermore, an installation seat 470 can be provided on the base 400, and the transmission shaft 230 is rotatably passed through the installation seat 470. Among them, the installation seat 470 can support the transmission shaft 230, so that the transmission shaft 230 can rotate more smoothly. Bearings can be provided on the installation seat 470. Among them, the transmission shaft 230 is rotationally connected to the installation seat 470 through the bearings.

[0055] The first lead screw 211 and the second lead screw 221 can be synchronously rotationally connected to the drive shaft 230 through devices such as couplings. In addition, other structures, such as the cooperation of keys and keyways, can also be used to achieve synchronous rotational connection between the shafts.

[0056] A first connecting seat 421 and a second connecting seat 422 are fixedly arranged on the base 400. One end of the first lead screw 211 close to the drive shaft 230 is connected to the first connecting seat 421, and bearings can be arranged on the first connecting seat 421. Among them, the first lead screw 211 is rotationally connected to the first connecting seat 421 through the bearings on the first connecting seat 421; one end of the second lead screw 221 close to the drive shaft 230 is connected to the second connecting seat 422, and bearings can be arranged on the second connecting seat 422. Among them, the second lead screw 221 is rotationally connected to the second connecting seat 422 through the bearings on the second connecting seat 422.

[0057] A first support seat 431 and a second support seat 432 are fixedly arranged on the base 400. One end of the first lead screw 211 away from the drive shaft 230 is connected to the first support seat 431, and bearings can be arranged on the first support seat 431. Among them, the first lead screw 211 is rotationally connected to the first support seat 431 through the bearings on the first support seat 431; one end of the second lead screw 221 away from the drive shaft 230 is connected to the second support seat 432, and bearings can be arranged on the second support seat 432. Among them, the second lead screw 221 is rotationally connected to the second support seat 432 through the bearings on the second support seat 432.

[0058] For the first scissor lift mechanism 101, one end of its first connecting rod 110 is rotationally connected to the first support seat 431, and the other end is rotationally connected to its own second connecting rod 120; for the second scissor lift mechanism 102, one end of its first connecting rod 110 is rotationally connected to the second support seat 432, and the other end is rotationally connected to its own second connecting rod 120.

[0059] In this embodiment, the bearings installed at different positions can be selected according to the actual usage conditions. For example, according to the force and load conditions, angular contact ball bearings, deep groove ball bearings, etc. can be selected for use.

[0060] The drive shaft 230 is drivingly connected to a drive device, and the drive device is used to drive the drive shaft 230 to rotate.

[0061] The drive device includes a drive motor 240, a first transmission wheel 241 and a second transmission wheel 242, and the first transmission wheel 241 is drivingly connected to the second transmission wheel 242. The output shaft of the drive motor 240 is connected to the first transmission wheel 241, and the second transmission wheel 242 is arranged on the drive shaft 230.

[0062] In this embodiment, a speed reducer 250 is connected to the output shaft of the drive motor 240. Among them, the output shaft of the drive motor 240 is connected to the first transmission wheel 241 through the speed reducer 250. The speed reducer 250 can play a role in reducing speed and increasing torque, so that the transmission shaft 230 can obtain a greater torque, and then the first scissor lift mechanism 101 and the second scissor lift mechanism 102 can drive heavier objects to lift. The specific structure of the speed reducer 250 can refer to the existing design and will not be elaborated herein.

[0063] The second transmission wheel 242 is sleeved on the transmission shaft 230, and the second transmission wheel 242 is rotationally connected to the transmission shaft 230 synchronously. Key grooves can be provided on the inner hole wall of the second transmission wheel 242 and the outer peripheral wall of the transmission shaft 230. Among them, through the cooperation between the key and the key groove, the synchronous rotation connection between the second transmission wheel 242 and the transmission shaft 230 can be realized.

[0064] The types of the first transmission wheel 241 and the second transmission wheel 242 can be selected according to needs. For example, in one embodiment, the first transmission wheel 241 and the second transmission wheel 242 can also adopt sprockets, and the first transmission wheel 241 and the second transmission wheel 242 are connected by a chain; in another embodiment, the first transmission wheel 241 and the second transmission wheel 242 can also adopt gears, and the first transmission wheel 241 and the second transmission wheel 242 are connected through a gear set or the like.

[0065] In this embodiment, both the first transmission wheel 241 and the second transmission wheel 242 can adopt belt pulleys, and the first transmission wheel 241 and the second transmission wheel 242 are connected through a timing belt 243.

[0066] A motor bracket 440 is fixedly provided on the base 400. Among them, the drive motor 240 and the speed reducer 250 are both installed on the motor bracket 440. Among them, a shielding cover 441 is provided on the motor bracket 440, and the first transmission wheel 241 can be shielded and protected through the shielding cover 441.

[0067] Further, an idler wheel 260 is rotatably installed on the motor bracket 440, and the idler wheel 260 is in contact with the outer side of the timing belt 243. Among them, by adjusting the position of the idler wheel 260, the tension of the timing belt 243 can be adjusted, thereby avoiding the situation of the timing belt 243 slipping. Refer to Figure 1 An adjusting bolt 261 is provided on the rotating shaft of the idler wheel 260, and the adjusting bolt 261 is threadedly connected to the motor bracket 440. Among them, by rotating the adjusting bolt 261, the position of the idler wheel 260 can be adjusted, and thus the tension of the timing belt 243 can be adjusted.

[0068] In this embodiment, a first guide shaft 451 and a second guide shaft 452 are provided on the base 400. Two ends of the first guide shaft 451 are fixedly connected to a first connecting seat 421 and a first support seat 431 respectively, and two ends of the second guide shaft 452 are fixedly connected to a second connecting seat 422 and a second support seat 432 respectively.

[0069] The first guide shaft 451 is parallel to the first lead screw 211. Among them, the first guide shaft 451 is used to guide the first nut seat 212, so that the first guide shaft 451 translates in a direction parallel to the first lead screw 211. The second guide shaft 452 is parallel to the second lead screw 221. Among them, the second guide shaft 452 is used to guide the second nut seat 222, so that the second guide shaft 452 translates in a direction parallel to the second lead screw 221.

[0070] The guiding of the first nut seat 212 can be realized through the first guide shaft 451, so as to ensure that the first nut seat 212 can move linearly stably; the guiding of the second nut seat 222 can be realized through the second guide shaft 452, so as to ensure that the second nut seat 222 can move linearly stably.

[0071] Specifically, the first guide shaft 451 passes through the first sliding seat 411 and is slidably connected to the first sliding seat 411; the second guide shaft 452 passes through the second sliding seat 412 and is slidably connected to the second sliding seat 412. Since the first nut seat 212 is fixed on the first sliding seat 411 and the second nut seat 222 is fixed on the second sliding seat 412, the first guide shaft 451 guides the first sliding seat 411, and the second guide shaft 452 guides the second sliding seat 412, thereby realizing the guiding of the first nut seat 212 and the second nut seat 222.

[0072] In this embodiment, the carrier seat 300 includes a first mounting portion 310, a second mounting portion 320, and a connecting portion 330. The first mounting portion 310 is connected to the first scissor lift mechanism 101, and the second mounting portion 320 is connected to the second scissor lift mechanism 102. Among them, the connecting portion 330 is disposed between the first mounting portion 310 and the second mounting portion 320, and both the first mounting portion 310 and the second mounting portion 320 are fixedly connected to the connecting portion 330.

[0073] Specifically, the second link 120 of the first scissor lift mechanism 101 is rotatably connected to the first mounting portion 310, and the second link 120 of the second scissor lift mechanism 102 is rotatably connected to the second mounting portion 320. The sides of the first mounting portion 310 and the second mounting portion 320 can be provided with a transfer shaft 340, and the end of the second link 120 can be provided with a transfer hole corresponding to the transfer shaft 340. Among them, the transfer shaft 340 is inserted into the corresponding transfer hole, and the transfer shaft 340 can rotate relative to the transfer hole. After the transfer shaft 340 and the second link 120 are assembled, a release prevention member 341 can be installed on the transfer shaft 340, and the release prevention member 341 can prevent the transfer shaft 340 and the second link 120 from becoming loose. For example, the transfer shaft 340 can be provided with a thread, and the release prevention member 341 can be a limit nut. By screwing the limit nut onto the transfer shaft 340, the limit of the second link 120 can be achieved, thereby preventing the transfer shaft 340 and the second link 120 from becoming loose.

[0074] In this embodiment, the lifting adjustment device further includes a detection device 500 for detecting the height position of the carrier 300.

[0075] The detection device 500 includes a trigger unit 510, a first detection unit 520, and a second detection unit 530. The first detection unit 520 and the second detection unit 530 are arranged in sequence in the vertical direction, and the trigger unit 510 is fixedly connected to the carrier 300. Among them, the carrier 300 has a first height position and a second height position:

[0076] When the carrier 300 moves to the first height position, the first detection unit 520 is triggered by the trigger unit 510, thereby generating a first signal; when the carrier 300 moves to the second height position, the second detection unit 530 is triggered by the trigger unit 510, thereby generating a second signal. Among them, the first height position is above the second height position, and the first detection unit 520 is above the second detection unit 530.

[0077] As Figure 1 and Figure 5 shown, on one side of the base 400 close to the first mounting portion 310 of the carrier 300, a mounting bracket 460 can be provided. Both the first detection unit 520 and the second detection unit 530 are provided on the mounting bracket 460, and the trigger unit 510 is fixed to the side of the first mounting portion 310.

[0078] As Figure 5As shown, the first detection unit 520 can be fixed to the first receiving seat 541 by means of bolt connection or the like, and the second detection unit 530 can be fixed to the second receiving seat 542 by means of bolt connection or the like. Both the first receiving seat 541 and the second receiving seat 542 can be fixedly connected to the mounting bracket 460 by means of bolt connection. Springs can be sleeved on the connecting bolts, thereby improving the connection stability, preventing the bolts from loosening and playing roles such as buffering and shock absorption.

[0079] In this embodiment, the first detection unit 520 and the second detection unit 530 respectively include a first U-shaped photoelectric sensor and a second U-shaped photoelectric sensor, and the triggering unit 510 can adopt a photoelectric detection board. When the carrier seat 300 moves to the first height position, the photoelectric detection board just leaves the U-shaped groove of the first U-shaped photoelectric sensor, thereby generating a first signal; when the carrier seat 300 moves to the second height position, the photoelectric detection board just inserts into the U-shaped groove of the second U-shaped photoelectric sensor, thereby generating a second signal.

[0080] In one embodiment, the first detection unit 520 and the second detection unit 530 can respectively include a first travel switch and a second travel switch, and the triggering unit 510 can adopt a stop block. When the carrier seat 300 moves to the first height position, the stop block collides with the contact of the first travel switch and makes the contact move, thereby generating a first signal; when the carrier seat 300 moves to the second height position, the stop block collides with the contact of the second travel switch and makes the contact move, thereby generating a second signal.
