Technical Field

[0001] This invention relates to the field of testing machine debugging equipment technology, and in particular to a docking vehicle. Background Technology

[0002] With the continuous emergence of new types of chips, the performance and structural complexity of testing machines used for chip testing are also increasing, leading to a gradual increase in the size and weight of these machines, which are now in the ton range.

[0042] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0044] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0045] like Figures 1 to 3 As shown, the docking vehicle provided in this embodiment of the invention includes: a frame 100, a translation mechanism 200 and a flipping mechanism 300. The translation mechanism 200 is installed on the frame 100 and is slidably connected to the frame 100 in the horizontal direction. The flipping mechanism 300 is installed on the translation mechanism 200. The flipping mechanism 300 is used to support the workpiece being debugged and to drive the workpiece being debugged to flip.

[0046] In the docking vehicle provided in this embodiment of the invention, the frame 100 supports the translation mechanism 200 and the flipping mechanism 300. The translation mechanism 200 drives the flipping mechanism 300 to move horizontally. The flipping mechanism 300 is mounted on the translation mechanism 200 and supports the workpiece to be tested, and drives the workpiece to flip. When adjusting the position of the testing machine, the testing machine can be placed on the flipping mechanism 300. The translation mechanism 200 can drive the flipping mechanism 300 and the testing machine to move horizontally, so that the testing machine moves to a suitable position. The flipping mechanism 300 can drive the testing machine to switch between a horizontal state and a flipped state, so that the testing machine is in the required state.

[0047] Compared with the prior art, the docking vehicle provided in this embodiment of the invention can not only drive the test machine to move horizontally, but also realize the flipping of the test machine, thus increasing its functions and meeting different needs when debugging the test machine.

[0048] Specifically, such as Figure 1 and Figure 4As shown, the frame 100 is a rectangular frame arranged horizontally, with the translation mechanism 200 and the tilting mechanism 300 both located above the frame 100. The frame 100 has two parallel and spaced-apart first support rods 120. The translation mechanism 200 slides along the length of the first support rods 120 and engages with the two first support rods 120. Multiple casters 140 (e.g., two, three, or four) are fixedly mounted on the outer walls of each of the two first support rods 120. These casters 140 are spaced along the length of their respective first support rods 120 and support the frame 100, allowing the docking vehicle to move as a whole. Multiple support feet 150 (e.g., two, three, or four) are fixedly mounted on the lower surfaces of each of the two first support rods 120, also spaced along the length of their respective first support rods 120. Each support leg 150 is threaded into its corresponding first support rod 120, allowing for lifting and lowering relative to the support leg 150. When the docking vehicle needs to be moved, the support leg 150 is screwed upwards, causing the four casters 140 to contact the ground. When the docking vehicle is moved to the desired position, the support leg 150 is screwed downwards, with the multiple support legs 150 working together to support the entire docking vehicle, and the casters 140 leaving the ground, thus preventing the docking vehicle from moving during commissioning.

[0049] like Figure 4 As shown, the frame 100 also includes two second support rods 130, which are parallel to and spaced apart along the length of the first support rod 120. The two ends of each second support rod 130 are fixedly connected to the two first support rods 120. One of the second support rods 130 is equipped with multiple docking blocks 131, such as two, three, or four, which are spaced apart along the length of the second support rod 130. Each docking block 131 has a docking surface, which is parallel to and spaced apart from the outer wall of the second support rod 130, and has two docking grooves whose length is parallel to the length of the second support rod 130. During commissioning, the docking vehicle is connected to the docking equipment via the docking blocks 131.

[0050] The translation mechanism 200 includes a translation drive assembly, a translation transmission assembly 220, and a translation assembly 230. The translation assembly 230 is slidably connected to the frame 100, and the translation transmission assembly 220 is connected to both the translation drive assembly and the translation assembly 230. The flipping mechanism 300 is mounted on the translation assembly 230. Specifically, the translation assembly 230 is slidably engaged with two first support rods 120. The translation drive assembly, the translation transmission assembly 220, and the flipping mechanism 300 are all mounted on the translation assembly 230, and the translation transmission assembly 220 is drively connected to both the translation drive assembly and the translation transmission assembly 220. During debugging, the translation drive assembly transmits power to the translation assembly 230 through the translation transmission assembly 220. The translation assembly 230 drives the flipping mechanism 300 and the testing machine placed on the flipping mechanism 300 to move, thereby adjusting the position of the testing machine.

[0051] like Figure 1 As shown, the translation component 230 includes a support base plate 231 and a slider 232. The flipping mechanism 300 is installed on the upper end face of the support base plate 231, and the slider 232 is installed on the lower end face of the support base plate 231. A slide rail 110 is installed on the side of the frame 100 facing the support base plate 231, and the slider 232 slides in cooperation with the slide rail 110.

[0052] Specifically, the translation component 230 includes two support base plates 231, both horizontally positioned and correspondingly positioned above the two first support rods 120. Both support base plates 231 are rectangular, and their length direction is parallel to that of the first support rod 120. Multiple sliders 232 (e.g., two, three, or four) are mounted on the lower surface of each support base plate 231, spaced apart along its length. Mounting plates 121 are fixedly mounted on the upper surfaces of both first support rods 120. These mounting plates 121 are rectangular and their length direction is parallel to that of the first support rod 120. A slide rail 110 is fixedly mounted on the upper surface of each mounting plate 121, and the slide rail 110's length direction is parallel to that of the corresponding first support rod 120. The length of the slide rail 110 and the length of the mounting plate 121 are both less than the length of the first support rod 120, and the end of the mounting plate 121 near the docking block 131 is flush with the end face of the first support rod 120.

[0053] The translation drive assembly includes a handwheel 211 and a drive rod 212. The drive rod 212 is vertically oriented and is connected to the handwheel 211 via a bevel gear set. The lower end of the drive rod 212 passes through the support base plate 231 from top to bottom. The translation transmission assembly 220 includes a meshing transmission gear 221 and a transmission rack 222. The transmission rack 222 is fixedly mounted on the upper surface of the mounting plate 121, and its length direction is parallel to the length direction of the slide rail 110. The transmission gear 221 is located below the support base plate 231 and is fixedly mounted on the lower end of the drive rod 212.

[0054] When adjusting the position of the horizontally adjusted flipping mechanism 300, the operator rotates the handwheel 211 to rotate the drive rod 212. The drive rod 212 drives the transmission gear 221 to rotate. The transmission gear 221 cooperates with the transmission rack 222 to move the support base plate 231 along the length direction of the first support rod 120. This causes the support base plate 231 to drive the flipping mechanism 300 to move along the length direction of the first support rod 120, thereby adjusting the position of the testing machine.

[0055] Furthermore, each mounting plate 121 is equipped with two limiting blocks 122, which are located at both ends of the slide rail 110 to limit the movement range of the support base plate 231.

[0056] like Figure 5 As shown, the flipping mechanism 300 includes a support frame 310, a carrier 320, and a telescopic drive assembly 330. The carrier 320 is rotatably connected to the support frame 310 via a rotating shaft 700. The drive end of the telescopic drive assembly 330 is connected to the carrier 320 via a transmission connection. The telescopic drive assembly 330 is used to drive the carrier 320 to rotate around the rotating shaft 700, so that the carrier 320 switches between a horizontal state and a flipped state.

[0057] The support frame 310 supports the carrier component 320, which in turn supports the testing machine. The telescopic drive assembly 330 drives the carrier component 320 to rotate around the rotation axis 700, allowing the carrier component 320 to switch between a horizontal and a flipped state. During debugging and testing of the testing machine, the testing machine is mounted on the carrier component 320, and the telescopic drive assembly 330 drives the carrier component 320 to rotate around the rotation axis 700, thus flipping the testing machine.

[0058] Compared with the existing technology of a flipping mechanism that transmits torque to a rotating shaft, the flipping mechanism 300 in this embodiment of the invention transmits power to the bearing 320. The lever arm from the flipping center to the thrust fulcrum is increased, and the input driving force is smaller when flipping a test machine of the same weight, thus enabling it to adapt to the flipping motion of a heavy-duty test head.

[0059] like Figure 5 and Figure 9As shown, the support frame 310 includes two spaced support walls 311, which are installed above the support base plate 231. The bearing member 320 is located between the two support walls 311 and is rotatably connected to the two support walls 311 one by one through two rotating shafts 700.

[0060] Specifically, both support walls 311 are vertically aligned and parallel to each other. One support wall 311 is fixedly mounted on the upper surface of a support base plate 231, and the other support wall 311 is fixedly mounted on the upper surface of another support base plate 231. A load-bearing member 320 is located between the two support walls 311. The sidewalls of the load-bearing member 320 and the two support walls 311 are rotatably connected to their respective support walls 311 via a rotating shaft 700. When a testing machine is placed on the load-bearing member 320, since the load-bearing member 320 is located between the two support walls 311, and support base plates 231 are provided below each of the two support walls 311, the center of gravity of the testing machine is located within the internal area of ​​the support frame 310, avoiding a cantilever beam structure and thus improving the load-bearing capacity of the tilting mechanism 300. Furthermore, because a cantilever beam structure is avoided, there is no need for a counterweight box and diffused foot supports, simplifying the structure of the tilting mechanism 300 and reducing the space it occupies.

[0061] In one embodiment of this application, such as Figure 5 and Figure 8 As shown, the support member 320 has a first sidewall 321 and a second sidewall 322 that are opposite to each other. The first sidewall 321 and the second sidewall 322 are rotatably connected to the support frame 310 via a rotating shaft 700. Specifically, the support member 320 is a flip frame with a rectangular cross-section. The two sidewalls of the flip frame that are parallel to its own length direction are the first sidewall 321 and the second sidewall 322, respectively. The flip frame is located between two support walls 311. The first sidewall 321 is rotatably connected to one of the support walls 311 via a rotating shaft 700, and the second sidewall 322 is rotatably connected to the other support wall 311 via another rotating shaft 700. The rotating shafts 700 on the first sidewall 321 and the second sidewall 322 are coaxially arranged.

[0062] Furthermore, the docking vehicle provided in this embodiment of the invention also includes a tank chain 160. One end of the tank chain 160 is connected to the frame 100, and the other end is connected to one end of the flipping frame. The bottom of the tank chain 160 rests on the bottom connecting plate to constrain the movement path of the conduit when the testing machine rotates.

[0063] As one implementation of driving the flip frame, the driving end of the telescopic driving component 330 is movably connected to one end of the flip frame in the length direction. By driving the flip frame to move up and down at the end connected to the telescopic driving component 330, the flip frame can rotate around the axis of the rotation shaft 700.

[0064] In one embodiment of this application, two telescopic drive components 330 are provided. One telescopic drive component 330 is located between the first sidewall 321 and the support wall 311 opposite to the first sidewall 321, and the other telescopic drive component 330 is located between the second sidewall 322 and the support wall 311 opposite to the second sidewall 322. The drive ends of the two telescopic drive components 330 are movably connected to the first sidewall 321 and the second sidewall 322, respectively.

[0065] When the test machine is flipped, the two telescopic drive components 330 exert force on the carrier 320 simultaneously. Since the two telescopic drive components 330 are located on both sides of the carrier 320, the carrier 320 is subjected to uniform force, thereby improving the stability of the test machine when the carrier 320 drives it to flip.

[0066] In one embodiment, the telescopic drive assembly includes a cylinder, the cylinder body 410 of which is hinged to the support frame 310, the piston rod of which is hinged to the carrier 320, and the hinge shafts at both ends of the cylinder are parallel to the rotation shaft 700. The cylinder performs telescopic movements, thereby driving the carrier 320 to rotate around the axis of the rotation shaft 700.

[0067] In one embodiment of this application, such as Figure 9 As shown, the telescopic drive assembly 330 includes an electric cylinder 400 and a commutator 500, and the tilting mechanism 300 also includes a rotary drive assembly; the commutator 500 is mounted on the support frame 310 and connected to the electric cylinder 400 and the rotary drive assembly.

[0068] Specifically, such as Figures 10 to 13As shown, the electric cylinder 400 includes a cylinder body 410, a lead screw 420, and a telescopic assembly 430. The telescopic assembly 430 includes a transmission nut 431, a push rod 432, and a limiting bushing 433. One end of the cylinder body 410 is connected to the commutator 500. The cylinder body 410 is cylindrical, and both its inner and outer walls have rectangular cross-sections. The length of the cylinder body 410 is axially aligned with the output shaft 540. The lead screw 420 is axially aligned with and rotatably connected to the cylinder body 410. One end of the lead screw 420 is located inside the cylinder body 410, and the other end extends from the end of the cylinder body 410 near the commutator housing 510 and is connected to one end of the output shaft 540. The lead screw 420 and the output shaft 540 are coaxially aligned. A transmission nut 431 is sleeved on a lead screw 420 and threadedly engaged with it. A limiting sleeve 433 is sleeved on the outside of the transmission nut 431 and the lead screw 420 and is fixedly connected to the transmission nut 431 by screws. The outer peripheral wall of the limiting sleeve 433 abuts against the inner wall of the cylinder body 410 to prevent the transmission nut 431 from rotating with the lead screw 420 when the lead screw 420 rotates. The push rod 432 has an annular cross-section and is arranged along the axial direction of the lead screw 420, sleeved on the outside of the lead screw 420. One end of the push rod 432 is located inside the cylinder body 410 and is fixedly connected to the limiting sleeve 433. The other end of the push rod 432 extends from the end of the cylinder body 410 away from the commutator 500. A second fixing seat 325 is provided on both the first side wall 321 and the second side wall 322 of the bearing member 320, such as... Figure 6 As shown, the second fixed seat 325 has a second opening groove facing the electric cylinder 400. A fixed shaft 3251 is provided in the second opening groove and is parallel to the rotating shaft 700. The two ends of the fixed shaft 3251 are fixedly connected to the two side walls of the second opening groove respectively. One end of the push rod 432 extending out of the cylinder body 410 is rotatably connected to the fixed shaft 3251 through a spherical bearing 435.

[0069] The commutator 500 includes a commutator housing 510, a commutator drive assembly 520, and an input shaft 530 and an output shaft 540, both of which are rotatably connected to the commutator housing 510. The input shaft 530 is movably inserted through the commutator housing 510, and the output shaft 540 is set at an angle to the input shaft 530 and is drively connected to the input shaft 530 through the commutator drive assembly 520.

[0070] Furthermore, the input shaft 530 penetrates the reversing housing 510, and both ends of the input shaft 530 are located outside the reversing housing 510.

[0071] Specifically, along the axial direction of the input shaft 530, the reversing housing 510 has two parallel first support walls 512. The input shaft 530 is rotatably connected to the two first support walls 512 via second bearings, and its two ends extend out of the corresponding first support walls 512. The output shaft 540 is located on one side of the input shaft 530, and the axis of the output shaft 540 is set at an angle to the axis of the input shaft 530. The reversing transmission assembly 520 is connected to both the input shaft 530 and the output shaft 540, and the input shaft 530 transmits power to the output shaft 540 through the reversing transmission assembly 520.

[0072] like Figure 7 and Figure 9 As shown, the support frame 310 also includes a first fixed seat 312. Two first fixed seats 312 are provided, and both first fixed seats 312 are bolted to the end of the corresponding support base plate 231 near the electric cylinder 400. The first fixed seat 312 has a first opening groove, and the opening of the first opening groove is opened away from the support base plate 231. The reversing housing 510 is located in the first opening groove. The axis of the input shaft 530 is perpendicular to the axis of the lead screw 420. The input shaft 530 is connected to the output shaft 540 through the reversing transmission assembly 520. The two ends of the input shaft 530 extending out of the reversing housing 510 pass through the two side walls of the first fixed seat 312, and one of the protruding ends is connected to the rotary drive assembly.

[0073] During the rotation of the load-bearing component 320, the rotary drive assembly transmits rotational power to the input shaft 530. The input shaft 530 drives the lead screw 420 to rotate around its axis via the reversing transmission assembly 520. The transmission nut 431 engages with the lead screw 420 to convert the rotational motion into linear motion, thereby causing the transmission nut 431 to extend or retract the push rod 432 into the cylinder 410, thus enabling the load-bearing component 320 to switch between a horizontal and a rotated state. The telescopic drive assembly 330 reverses the received power via the reversing device 500, expanding the installation space for the rotary drive assembly and making the structure of the rotating mechanism 300 more compact.

[0074] Furthermore, in the telescopic drive assembly 330 provided in this embodiment of the invention, both ends of the input shaft 530 extend out of the reversing housing 510, thereby allowing either end of the input shaft 530 to be connected to an external power input assembly. The telescopic assembly 430 is used for connection to the driven component. During the driving process, the input shaft 530 receives power transmitted from the external power input assembly and rotates around its own axis. The input shaft 530 drives the output shaft 540 to rotate through the reversing transmission assembly 520. The output shaft 540 drives the lead screw 420 to rotate around its own axis. The telescopic assembly 430 is threadedly engaged with the lead screw 420, causing the telescopic assembly 430 to perform telescopic movement relative to the cylinder 410, thereby driving the driven component connected to it to move.

[0075] Compared with the telescopic drive assembly in the prior art where the axis of the input shaft 530 is parallel to the axis of the lead screw 420, in this embodiment of the telescopic drive assembly 330, both ends of the input shaft 530 extend out of the reversing housing 510, and the input shaft 530 and the output shaft 540 are set at an angle. Both ends of the input shaft 530 can be used as input ends to connect to the power input assembly, reducing the restriction on the installation position of the power source and thus expanding the installation space of the power source. In addition, the angle between the input shaft 530 and the output shaft 540 reduces interference between the rotary drive assembly and the telescopic drive assembly 330 when the rotary drive assembly is connected to the input shaft 530, thereby reducing the restriction on the installation position of the rotary drive assembly and expanding the installation space of the rotary drive assembly.

[0076] like Figure 9 As shown, the rotary drive assembly includes a rotary drive component 810 and a synchronous transmission component 820, which is connected to both the rotary drive component 810 and the commutator 500. Specifically, the rotary drive component 810 can be a motor or a rotary cylinder, etc. In this embodiment, the rotary drive component 810 is a motor. The power input end of the synchronous transmission component 820 is connected to the motor, and the synchronous transmission component 820 has two power output ends, which are respectively connected to the commutators 500 on both sides of the support component 320. The two commutators 500 transmit power to the corresponding electric cylinders 400. During the flipping process, the rotary drive component 810 drives the synchronous transmission component 820 to move, and the synchronous transmission component 820 drives the commutators 500 on both sides of the support component 320 to move synchronously, thereby causing the electric cylinders 400 on both sides of the support component 320 to move synchronously and simultaneously apply force to the support component 320, so that the force on both sides of the support component 320 is even, improving the stability of the support component 320 during flipping.

[0077] In one embodiment of this application, the synchronous transmission assembly 820 includes a synchronous shaft 821 connected to a rotary drive 810. One end of the synchronous shaft 821 is connected to one of the commutators 500, and the other end of the synchronous shaft 821 is connected to another commutator 500.

[0078] Specifically, such as Figure 9As shown, the flipping mechanism 300 also includes a mounting bracket 313, which is located between two first fixed seats 312, and both ends are fixedly connected to the corresponding first fixed seats 312. The motor housing is fixedly mounted on the mounting bracket 313. The synchronous transmission assembly 820 also includes a reducer 830. A third fixed seat 314 is fixedly mounted on the mounting bracket 313, and the position of the third fixed seat 314 corresponds to the position of the motor. The reducer 830 is fixedly mounted on the third fixed seat 314. The motor is connected to the input shaft of the reducer 830, and the synchronous shaft 821 passes through the reducer 830 and is connected to the input shaft of the reducer 830 through a bevel gear set. The synchronous transmission assembly also includes a coupling 822. One end of the synchronous shaft 821 is connected to the input shaft 530 of one commutator 500 through the coupling 822, and the other end of the synchronous shaft 821 is connected to the input shaft 530 of the other commutator 500 through the coupling 822.

[0079] When the drive bearing 320 rotates around the axis of the rotating shaft 700, the motor drives the reducer 830 to rotate. The reducer 830 drives the input shaft 530 of the two commutators 500 to rotate through the synchronous shaft 821. The output shaft 540 of each commutator 500 drives the lead screw 420 in the corresponding electric cylinder 400 to rotate, so that the push rods 432 in the two electric cylinders 400 perform synchronous extension and retraction movements. The two push rods 432 apply force to the bearing 320 at the same time, so that the force on both sides of the bearing 320 is even, improving the stability of the bearing 320 when it is flipped.

[0080] In another embodiment, the synchronous transmission assembly 820 includes a first transmission shaft and a second transmission shaft, both of which are connected to the rotary drive member 810. The first transmission shaft is driven to one of the commutators 500, and the second transmission shaft is driven to the other commutator 500.

[0081] Specifically, the reducer 830 is configured as a dual-output shaft reducer and is fixedly installed on the third fixed base 314. The motor is connected to the input shaft of the reducer 830, and the axes of both output shafts of the reducer 830 are parallel to the axis of the rotating shaft 700. The first drive shaft and the second drive shaft are located on both sides of the reducer 830, respectively. The two ends of the first drive shaft are connected to one of the output shafts of the reducer 830 and the input shaft 530 of the corresponding side commutator 500, respectively. The two ends of the second drive shaft are connected to the other output shaft of the reducer 830 and the input shaft 530 of the corresponding side commutator 500, respectively.

[0082] When the drive bearing 320 rotates around the axis of the rotating shaft 700, the motor drives the reducer 830 to rotate. The reducer 830 drives the input shaft 530 of the two commutators 500 to rotate through the first transmission shaft and the second transmission shaft, respectively. The output shaft 540 of the commutator 500 drives the lead screw 420 in the corresponding electric cylinder 400 to rotate, so that the push rod 432 in the two electric cylinders 400 performs synchronous extension and retraction movements. The two push rods 432 apply force to the bearing 320 at the same time, so that the force on both sides of the bearing 320 is even, improving the stability of the bearing 320 when it is flipped.

[0083] As another implementation of synchronous transmission, the synchronous transmission assembly 820 includes a gear set, which transmits the power of the rotary drive 810 to the input shafts 530 of the two commutators 500, thereby realizing the synchronous extension and retraction of the two electric cylinders 400.

[0084] In one embodiment of this application, both the rotary drive 810 and the synchronous shaft 821 are located below the support member 320. Specifically, the mounting bracket 313 is located below the support member 320, with both ends connected to two first fixed seats 312 respectively. Both the rotary drive 810 and the synchronous shaft 821 are mounted on the mounting bracket 313. By placing both the rotary drive 810 and the synchronous shaft 821 below the support member 320, the internal space of the flipping mechanism 300 is utilized efficiently, making the structure of the flipping mechanism 300 more compact.

[0085] The carrier 320 has a first end 323 and a second end 324. When the carrier 320 is in a flipped state, the first end 323 is located below the second end 324. The first end 323 and the second end 324 are the two ends of the carrier 320 along its length. The sidewall of the carrier 320 is rotatably connected to the support frame 310 via a rotating shaft 700. The distance between the rotating shaft 700 and the first end 323 is less than the distance between the rotating shaft 700 and the second end 324. Specifically, the distance between the rotating shaft 700 and the first end 323 is one-third of the length of the sidewall of the carrier 320, making the distance between the rotating shaft 700 and the first end 323 less than the distance between the rotating shaft 700 and the second end 324. When the carrier 320 is flipped, the center of gravity of the carrier 320 is lower, thereby improving the stability of the carrier 320 during flipping and thus improving the safety performance of the flipping mechanism 300.

[0086] In one embodiment of this application, such as Figure 13As shown, the output shaft 540 is perpendicular to the input shaft 530. Specifically, the reversing housing 510 also has a second support wall 513, which is located between two first support walls 512 and perpendicular to each of the two first support walls 512. One end of the output shaft 540 is located inside the reversing housing 510 and is connected to the input shaft 530 via the reversing transmission assembly 520. The other end of the output shaft 540 extends out of one of the second support walls 513 and is connected to the lead screw 420. The output shaft 540 is rotatably connected to the second support wall 513 via a third bearing. When the telescopic drive assembly 330 is installed on the corresponding support structure, both ends of the reversing housing 510 along the axial direction of the input shaft 530 cooperate with the corresponding support structure. Since the output shaft 540 is perpendicular to the input shaft 530, the cylinder 410 is located on one side of the reversing housing 510, avoiding interference between the cylinder 410 and the support structure.

[0087] In some embodiments, the reversing drive assembly 520 includes a worm gear and a worm. The worm is arranged axially along the input shaft 530 and connected to the input shaft 530. The worm gear is sleeved on the output shaft 540. Power is transmitted between the input shaft 530 and the output shaft 540 through the worm gear and worm wheel cooperation.

[0088] In one embodiment of this application, such as Figure 13 As shown, the reversing transmission assembly 520 includes a first bevel gear 521 and a second bevel gear 522 that mesh with each other. The first bevel gear 521 is fixedly sleeved on the input shaft 530, and the second bevel gear 522 is fixedly sleeved on the output shaft 540. Specifically, the first bevel gear 521 is fixedly sleeved in the middle of the input shaft 530, and the second bevel gear 522 is fixedly sleeved at one end of the output shaft 540 located inside the reversing housing 510. When the input shaft 530 rotates about its own axis, power is transmitted to the output shaft 540 through the meshing first bevel gear 521 and the second bevel gear 522, thereby causing the output shaft 540 to drive the lead screw 420 to rotate.

[0089] In some embodiments, one end of the output shaft 540 located outside the reversing housing 510 is connected via a coupling to the other end of the lead screw 420 located outside the cylinder block 410, thereby enabling the output shaft 540 to transmit power to the lead screw 420.

[0090] In one embodiment of this application, the output shaft 540 is provided with a connecting sleeve 541 at the end away from the input shaft 530, and one end of the lead screw 420 is detachably connected to the connecting sleeve 541.

[0091] Specifically, the connecting sleeve 541 is fixedly sleeved on the end of the output shaft 540 away from the input shaft 530. The end face of the connecting sleeve 541 facing away from the output shaft 540 has a connecting groove with a circular cross-section. Two openings facing the telescopic assembly 430 are provided on the sidewall of the connecting groove, penetrating the sidewall. Threaded through holes are provided on the two opposite sidewalls of the openings. The diameter of the end of the lead screw 420 connected to the output shaft 540 is equal to the diameter of the connecting groove. When connecting the lead screw 420 and the output shaft 540, the end of the lead screw 420 outside the cylinder body 410 is inserted into the connecting groove. The screw engages with the threaded through holes on the sidewall of the opening, thereby clamping the lead screw 420 to the sidewall of the connecting groove, thus connecting the lead screw 420 to the output shaft 540. When disassembling the lead screw 420 and the output shaft 540, the screw is unscrewed from the threaded through hole to release the restriction on the lead screw 420, allowing the lead screw 420 to be disassembled from the connecting sleeve 541, thus achieving the disassembly of the lead screw 420 from the output shaft 540. A connecting sleeve 541 is provided at one end of the output shaft 540, and the lead screw 420 is detachably connected to the output shaft 540 through the connecting sleeve 541, facilitating the connection and disassembly between the lead screw 420 and the output shaft 540. This facilitates the connection and cooperation of the telescopic drive assembly 330 with different commutators 500.

[0092] The telescopic drive assembly 330 also includes a connecting assembly, the two opposite end faces of which are connected to the cylinder 410 and the reversing housing 510 respectively, and one end of the lead screw 420 is movably inserted through the connecting assembly and connected to the output shaft 540.

[0093] Specifically, the connecting assembly is located between the reversing housing 510 and the cylinder block 410. The reversing housing 510 is connected to one side of the connecting assembly, and one end of the cylinder block 410 near the reversing housing 510 is fixedly connected to the other side of the connecting assembly. The reversing housing 510 and the cylinder block 410 are connected by the connecting assembly, and the lead screw 420 is connected to the output shaft 540 within the connecting assembly, which provides protection at the connection point.

[0094] Specifically, the connecting assembly includes a connecting plate 610 and a bearing housing 620. The bearing housing 620 is installed at one end of the cylinder body 410 near the reversing housing 510. The lead screw 420 is rotatably connected to the bearing housing 620 through a first bearing 621. The connecting plate 610 has a first end face and a second end face that are parallel to each other. The reversing housing 510 is detachably connected to the first end face, and the bearing housing 620 is detachably connected to the second end face.

[0095] Specifically, the bearing housing 620 is fixedly installed at one end of the cylinder body 410 near the reversing housing 510, and the lead screw 420 passes through the bearing housing 620 and is rotatably connected to the bearing housing 620 through two first bearings 621.

[0096] Specifically, the connecting plate 610 is square and has a first mounting through hole for the lead screw 420 to pass through. The connecting plate 610 is located between the reversing housing 510 and the bearing seat 620, and is perpendicular to the axis of the lead screw 420. A connecting seat 550 is provided on the second support wall 513 of the reversing housing 510. The connecting seat 550 has a second mounting through hole communicating with the first mounting through hole. The connecting sleeve 541 is located inside the second mounting through hole. The connecting seat 550 also has a third mounting through hole that penetrates the side wall of the second mounting through hole and is coaxially arranged with the threaded through hole on the connecting sleeve 541. A screw passes through the third mounting through hole and engages with the threaded through hole on the connecting sleeve 541, thereby clamping the lead screw 420. The outer peripheral wall of the connecting seat 550 has a rectangular cross-section, and its side length is smaller than the side length of the connecting plate 610. The connecting plate 610 has multiple first connecting through holes, all of which penetrate the connecting plate 610 along the axial direction of the lead screw 420. The connecting seat 550 is provided with a number of first threaded holes equal to the number of first connecting through holes. The positions of the multiple first threaded holes correspond one-to-one with the positions of the multiple first connecting through holes. The bolt passes through the first connecting through hole and engages with the corresponding first threaded hole, thereby realizing the detachable connection between the connecting seat 550 and the connecting plate 610.

[0097] The connecting plate 610 is also provided with a plurality of second connecting through holes, which surround the outer periphery of the connecting seat 550. The bearing seat 620 has a square end plate 622, the side length of which is equal to the side length of the connecting plate 610. The end plate 622 is provided with a plurality of second threaded holes, the number of which is equal to the number of the second connecting through holes. The positions of the plurality of second threaded holes correspond one-to-one with the positions of the plurality of second connecting through holes. Bolts pass through the second connecting through holes and engage with the corresponding second threaded holes to connect the connecting plate 610 and the bearing seat 620, thereby connecting the reversing housing 510 and the cylinder 410.

[0098] The connecting assembly includes a connecting plate 610 and a bearing housing 620, which enables a detachable connection between the reversing housing 510 and the cylinder block 410. At the same time, the connecting plate 610 and the bearing housing 620 have simple structures and can reduce the space occupied.

[0099] like Figure 13As shown, the lead screw 420 is provided with a limiting step 421 and an anti-reverse component 422. The first bearing 621 is located between the limiting step 421 and the anti-reverse component 422. The anti-reverse component 422 is used to prevent the lead screw 420 from dislodging from the bearing housing 620. Specifically, the limiting step 421 is located inside the cylinder body 410, and the first bearing 621 is located on the side of the limiting step 421 closer to the reversing housing 510. The anti-reverse component 422 is set as an anti-reverse nut, which is located on the side of the first bearing 621 opposite to the limiting step 421 and is threadedly engaged with the lead screw 420. A limiting space is formed between the anti-reverse nut and the first bearing 621. The two components, together with the first bearing 621, prevent the lead screw 420 from moving axially relative to the first bearing 621, thereby improving the stability of the lead screw 420 during movement.

[0100] Furthermore, a support sleeve 423 is fitted onto the end of the lead screw 420 away from the reversing housing 510. The end face of the support sleeve 423 near the reversing housing 510 abuts against the limiting surface on the lead screw 420. A retaining ring 424 is provided on the side of the support sleeve 423 away from the reversing housing 510. The retaining ring 424 is fixedly fitted onto the lead screw 420 and abuts against the support sleeve 423. The retaining ring 424 cooperates with the limiting surface to prevent the support sleeve 423 from moving axially along the lead screw 420. The outer peripheral wall of the support sleeve 423 abuts against the inner wall of the push rod 432 to prevent the end of the lead screw 420 away from the reversing housing 510 from shaking, thereby improving the stability of the lead screw 420 during rotation.

[0101] The telescopic assembly 430 also includes a connecting shaft 434 and a spherical bearing 435. The connecting shaft 434 is detachably connected to the end of the push rod 432 located outside the cylinder 410, and the spherical bearing 435 is adjustablely connected to the end of the connecting shaft 434 away from the push rod 432.

[0102] Specifically, the push rod 432 has an internal thread at one end outside the cylinder body 410. The connecting shaft 434 is detachably connected to the end of the push rod 432 away from the reversing housing 510. The connecting shaft 434 and the push rod 432 are threaded together, facilitating connection and disconnection between them. The end of the connecting shaft 434 away from the push rod 432 has an external thread. The end of the spherical bearing 435 connected to the connecting shaft 434 has a insertion hole, which is inserted into the connecting shaft 434 away from the cylinder body 410. An adjusting nut 436 is also fitted onto the connecting shaft 434. The adjusting nut 436 is threadedly engaged with the connecting shaft 434 and abuts against the spherical bearing 435. By rotating the adjusting nut 436, its position on the connecting shaft 434 can be adjusted, thereby adjusting the position of the spherical bearing 435 relative to the connecting shaft 434. The spherical bearing 435 is used to connect with an external driven component, so that the push rod 432 can rotate relative to the driven component, improving the flexibility of the drive.

[0103] Along the axial direction of the input shaft 530, both ends of the reversing housing 510 are provided with mounting steps 511, which are used to cooperate with the support structure. Specifically, both first support walls 512 of the reversing housing 510 are provided with mounting steps 511, which protrude from the corresponding first support wall 512 and have a circular cross-section. Both ends of the input shaft 530 extend from the two mounting steps 511 respectively. Specifically, the support structure can be two parallel and spaced support plates, both of which are provided with mounting holes, and the mounting holes on the two support plates are coaxially arranged. In this application, the support structure is the aforementioned first fixed seat 312, wherein both side walls of the first opening slot are provided with mounting holes, and the mounting holes on the two side walls of the first opening slot are coaxially arranged. When the reversing housing 510 is installed on the support structure, the mounting steps 511 at both ends of the reversing housing 510 are inserted into the two mounting holes respectively. The outer peripheral wall of the mounting step 511 abuts against the inner peripheral wall of the mounting hole, thereby supporting the electric push rod 432 and making the overall structure more compact.

[0104] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
