Description

Technical Field

[0001] This utility model relates to the field of intelligent robot chassis technology, specifically to a chassis frame mounting structure for an intelligent robot. Background Technology

[0002] A robot is a machine device that automatically performs tasks. It can be commanded by humans, run pre-programmed procedures, or act according to principles established by artificial intelligence technology. Its task is to assist or replace human workers in jobs such as manufacturing, construction, or hazardous work. Chinese robotics experts, based on their application environments, divide robots into two main categories: industrial robots and special-purpose robots. Industrial robots are multi-jointed manipulators or multi-degree-of-freedom robots designed for industrial applications. Special-purpose robots, on the other hand, are advanced robots used outside of manufacturing and serving humans, including service robots, underwater robots, entertainment robots, military robots, agricultural robots, and robotic machines. Within special-purpose robots, some branches are developing rapidly and showing a trend towards becoming independent systems, such as service robots, underwater robots, military robots, and micromanipulation robots. International robotics scholars, based on their application environments, also divide robots into two categories: industrial robots in manufacturing environments and service and humanoid robots in non-manufacturing environments, which is consistent with the Chinese classification.

[0003] Chinese Utility Model Patent Publication No. CN 217835835 U discloses a robot chassis frame structure. This robot chassis frame structure, through the arrangement of a first motor, a rotating rod, a drive wheel, a bracket, a second motor, a universal wheel, a storage frame, a protective frame, a spring, and a limiting rod, can realize the position movement and angle adjustment functions of the lower frame through the structural combination of the first motor, rotating rod, drive wheel, bracket, second motor, and universal wheel. The storage frame, protective frame, and limiting rod limit the storage trajectory of the protective frame, and the elastic force of the spring provides support for the protective frame, thereby preventing the chassis frame from colliding with obstacles and causing damage during movement. However, this robot chassis frame structure has a lifting structure, which cannot work at different heights and requires the use of support bases of different heights, resulting in low work efficiency. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a chassis frame mounting structure for an intelligent robot, which can effectively solve the problems in the prior art.

[0005] The technical solution adopted by this utility model is: a chassis frame installation structure for an intelligent robot, including a first base, a second base, and a support seat located on top of the first base and the second base. A protrusion is fixedly installed on the side of the second base near the first base. A slot 1 is opened on the side of the first base near the second base. A screw hole is opened on the top of the first base, and a locking screw is provided on the top of the screw hole. A groove is opened in the center of the inner top of the first base and the second base. A bridge frame 1 and a bridge frame 2 are provided on the top of the inner groove of the first base and the second base. A buckle assembly is provided on the side of the bridge frame 2 near the bridge frame 1. A pressing assembly is provided on the top of the bridge frame 2. A slot 2 is opened on the side of the bridge frame 1 near the bridge frame 2. A slide rail 2 is fixedly installed inside the support seat. A lifting assembly is provided in the center of the inner side of the support seat. A connecting plate is fixedly installed on the top of the lifting assembly.

[0006] The buckle assembly includes a fixed base, a circular plate, a return spring 1, and a locking block. The fixed base is fixedly installed on the side of the cable tray 2 near the cable tray 1. The circular plate is fixedly installed on the top of the inner side of the fixed base. The return spring 1 is fixedly installed on the top of the circular plate. The locking block is fixedly installed on the top of the return spring 1.

[0007] The pressing assembly includes a cylinder, a second return spring, a pressing post, a ring plate, and a pusher head. A cylinder is fixedly installed on the inner side of the top bridge frame of the card block. A second return spring is fixedly installed inside the cylinder. A pressing post is provided on the top of the second return spring. A pusher head is provided on the top of the pressing post. A ring plate is fixedly installed on the outer surface of the pressing post.

[0008] Preferably, multiple sets of support feet are fixedly installed at the bottom of the first base and the second base, a tank chain is provided at the top of the first bridge and the second bridge, a slide rail is fixedly installed at the top of the first base and the second base, a slider is slidably installed at the top of the slide rail, a fixing plate is provided on the side of the slider away from the slide rail, a positioning block is fixedly installed at the top of the fixing plate, a base plate is provided at the top of the positioning block, a locking nut is provided on the side of the base plate away from the positioning block, and a support seat and a reinforcing plate are fixedly installed at the top of the base plate.

[0009] The above technical solution enhances the robot's stability during operation by setting multiple sets of support feet, and enables the robot to move on the first and second bases by setting the slider and slide rail to slide, thereby increasing the robot's operating range and improving its efficiency.

[0010] Preferably, the slot is adapted to the protrusion, and the protrusion is fixed to the first base by a locking screw.

[0011] Through the above technical solution, the first base and the second base can be quickly connected by the matching of the slot and the protrusion. The connection between the first base and the second base can be strengthened by tightening screws. The detachable design of the first base and the second base makes it easy to add or reduce the number of bases for different working environments, thereby realizing the practicality of the robot base.

[0012] Preferably, the buckle assembly has two identical sets, which are symmetrically distributed on the side of the cable tray two. The fixing seat has the same cross-section as the slot two, and the buckle block is adapted to the top of the inner side of the slot two.

[0013] The above technical solution enables a quick connection between cable tray 1 and cable tray 2 by setting two sets of buckle components. Since the fixed seat and the slot 2 have the same cross-section, when the fixed seat is inserted into the slot 2, the slot 2 squeezes the locking block and the return spring 1, causing the locking block to move downward until it is inserted into the inside of the fixed seat and into the inside of the slot 2. At this point, the locking block matches the top of the inside of the slot 2, the return spring 1 returns to its original position, and the locking block pops out, thus locking the fixed seat and reducing the installation difficulty.

[0014] Preferably, the pressing assembly has two identical sets, which are symmetrically distributed at the top of the bridge frame. The radius of the ring plate is larger than the radius of the second reset spring, and the radius of the pressing post is smaller than the radius of the second reset spring. The bottom of the pressing post penetrates the second slot and contacts the locking block.

[0015] The above technical solution facilitates the quick disassembly of bridge frame one and bridge frame two by setting up a pressing component. By designing that the radius of the ring plate is larger than the radius of the second return spring and the radius of the pressing post is smaller than the radius of the second return spring, when the push button is pressed down, the ring plate drives the second return spring to move downward. Then, the bottom of the pressing post passes through the slot two and contacts the locking block, which can squeeze the locking block into the inside of the fixed base, thereby realizing the quick disassembly of bridge frame one and bridge frame two and improving the installation efficiency of the robot base.

[0016] Preferably, the lifting assembly includes a motor, a threaded rod, a threaded column, and a limiting plate. The motor is fixedly installed on the inner side of the top support seat of the base plate, the output end of the motor is fixedly installed with a threaded rod, the outer side of the threaded rod is threaded with a threaded column, and the bottom of the threaded column is fixedly installed with a limiting plate.

[0017] The above technical solution, by setting up a lifting component, enables the connection plate to be adjusted to different heights. This helps the robot adapt to different usage scenarios, thereby increasing the robot's working range and avoiding the need for support bases of different heights when working at different heights, which reduces work efficiency.

[0018] Preferably, the slide rails are provided in two identical sets, and the two sets of slide rails are symmetrically distributed inside the support base, and the limiting plate is slidably connected to the slide rails.

[0019] By using the above technical solution, and through the design of the sliding connection between the limiting plate and the slide rail, the threaded column can be limited during lifting and lowering, thus ensuring the stability of the threaded column during lifting and lowering, and thereby achieving the stability of the robot lifting and lowering at the top of the connecting plate.

[0020] Compared with the prior art, this utility model provides a chassis frame mounting structure for an intelligent robot, which has the following beneficial effects:

[0021] 1. The chassis frame installation structure of this intelligent robot is equipped with a lifting component. When the motor is started, the motor output drives the threaded rod to rotate. With the threaded installation of the threaded rod and the threaded column, the threaded column can be raised and lowered. Through the fixed connection between the threaded column and the connecting plate, the position of the connecting plate can be adjusted to different heights. This can help the robot adapt to different usage situations, effectively improve the robot's working range, avoid the need to use support bases of different heights when working at different heights, and improve work efficiency.

[0022] 2. The chassis frame installation structure of this intelligent robot can achieve quick connection between bridge frame one and bridge frame two by setting two sets of buckle components. Since the fixed seat and the slot two have the same cross-section, when the fixed seat is inserted into the slot two, the slot two squeezes the locking block and the return spring one, which drives the locking block to move downward until it is inserted into the inside of the fixed seat. When it is inserted into the inside of the slot two, the locking block matches the top of the inside of the slot two, the return spring one returns to its original position, and the locking block pops out, which has a locking effect on the fixed seat and prevents the fixed seat from sliding out of the slot two. The buckle components can be easily removed from the slot two by setting a pressing component. By designing that the radius of the ring piece is larger than the radius of the return spring two and the radius of the pressing post is smaller than the radius of the return spring two, it can be realized that when the pressing head is pressed down, the ring piece drives the return spring two to move downward. Then, the bottom of the pressing post penetrates the slot two and contacts the locking block, which can squeeze the locking block into the inside of the fixed seat, thereby realizing the quick disassembly of bridge frame one and bridge frame two.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Example 1: As Figure 1-8As shown, the present invention provides a chassis frame installation structure for an intelligent robot, including a first base 1, a second base 2, and a support seat 21 located on top of the first base 1 and the second base 2. A protrusion 5 is fixedly installed on the side of the second base 2 near the first base 1. A slot 6 is provided on the side of the first base 1 near the second base 2. A screw hole 7 is provided on the top of the first base 1. A locking screw 8 is provided on the top of the screw hole 7. A groove 4 is provided in the center of the inner top of the first base 1 and the second base 2. A bridge frame 9 and a bridge frame 10 are provided on the top of the groove 4 on the inner side of the first base 1 and the second base 2. A buckle assembly 11 is provided on the side of the bridge frame 10 near the bridge frame 9. A pressing assembly 12 is provided on the top of the bridge frame 10. A slot 13 is provided on the side of the bridge frame 10 near the bridge frame 20. A slide rail 24 is fixedly installed inside the support seat 21. A lifting assembly 23 is provided in the center of the inner side of the support seat 21. A connecting plate 25 is fixedly installed on the top of the lifting assembly 23.

[0034] The latching assembly 11 includes a fixing seat 1101, a circular plate 1102, a return spring 1103, and a locking block 1104. The fixing seat 1101 is fixedly installed on the side of the cable tray 2 10 near the cable tray 1 9. The circular plate 1102 is fixedly installed on the top of the inner side of the fixing seat 1101. The return spring 1103 is fixedly installed on the top of the circular plate 1102. The locking block 1104 is fixedly installed on the top of the return spring 1103.

[0035] The pressing assembly 12 includes a cylinder 1201, a second reset spring 1202, a pressing post 1203, an annular piece 1204, and a push head 1205. The cylinder 1201 is fixedly installed on the inner side of the top bridge frame 9 of the locking block 1104. The second reset spring 1202 is fixedly installed inside the cylinder 1201. The pressing post 1203 is provided on the top of the second reset spring 1202. The push head 1205 is provided on the top of the pressing post 1203. The annular piece 1204 is fixedly installed on the outer surface of the pressing post 1203.

[0036] Specifically, multiple sets of support feet 3 are fixedly installed at the bottom of the first base 1 and the second base 2. Tank chains 14 are provided on the top of the bridge frame 9 and the bridge frame 10. A slide rail 15 is fixedly installed on the top of the first base 1 and the second base 2. A slider 16 is slidably installed on the top of the slide rail 15. A fixing plate 17 is provided on the side of the slider 16 away from the slide rail 15. A positioning block 18 is fixedly installed on the top of the fixing plate 17. A base plate 20 is provided on the top of the positioning block 18. A locking nut 19 is provided on the side of the base plate 20 away from the positioning block 18. A support seat 21 and a reinforcing plate 22 are fixedly installed on the top of the base plate 20. The advantage is that by setting multiple sets of support feet 3, the stability of the robot during operation is enhanced. By setting the slider 16 to slide rail 15, the robot can be displaced on the first base 1 and the second base 2, improving the robot's operating range and thus enhancing the robot's efficiency.

[0037] Specifically, the slot 6 is adapted to the protrusion 5, and the protrusion 5 is fixed to the first base 1 by the locking screw 8. The advantage is that the first base 1 and the second base 2 can be quickly connected by the adaptation of the slot 6 and the protrusion 5. The connection between the first base 1 and the second base 2 can be strengthened by the locking screw 8. The detachable design of the first base 1 and the second base 2 makes it easy to add or reduce the number of bases for different working environments, thereby realizing the practicality of the robot base.

[0038] Specifically, the buckle assembly 11 has two identical sets, symmetrically distributed on the side of the cable tray 2 10. The fixed seat 1101 and the slot 2 13 have the same cross-section, and the locking block 1104 is adapted to the top of the inner side of the slot 2 13. The advantage is that by setting two sets of buckle assemblies 11, the cable tray 1 9 and the cable tray 2 10 can be quickly connected. Since the fixed seat 1101 and the slot 2 13 have the same cross-section, when the fixed seat 1101 is inserted into the slot 2 13, the slot 2 13 squeezes the locking block 1104. The return spring 1103 drives the locking block 1104 to move downward until it is inserted into the inside of the fixed seat 1101 until it is inserted into the inside of the slot 2 13. At this point, the locking block 1104 is adapted to the top of the inner side of the slot 2 13, the return spring 1103 returns to its original position, and the locking block 1104 pops out, which locks the fixed seat 1101 and reduces the installation difficulty.

[0039] Example 2: Figure 2-8 As shown, this is an improvement on the previous embodiment.

[0040] Specifically, two identical sets of pressing components 12 are provided, symmetrically distributed on the top of the cable tray 9. The radius of the ring plate 1204 is larger than the radius of the return spring 1202, and the radius of the pressing post 1203 is smaller than the radius of the return spring 1202. The bottom of the pressing post 1203 passes through the slot 13 and contacts the locking block 1104. The advantage is that by setting the pressing components 12, the cable tray 9 and the cable tray 10 can be quickly disassembled. The radius of the ring plate 1204 is larger than the radius of the return spring 1202. The design of having 202's radius and the radius of the pressing post 1203 smaller than the radius of the second return spring 1202 allows the ring plate 1204 to drive the second return spring 1202 downward when the pressing head 1205 is pressed down. Then, the bottom of the pressing post 1203 passes through the slot 13 and contacts the locking block 1104, which can squeeze the locking block 1104 into the inner side of the fixed base 1101. This enables the quick disassembly of the bridge frame 9 and the bridge frame 10, improving the installation efficiency of the robot base.

[0041] Specifically, the lifting assembly 23 includes a motor 2301, a threaded rod 2302, a threaded column 2303, and a limiting plate 2304. The motor 2301 is fixedly installed on the inner side of the top support seat 21 of the base plate 20. The threaded rod 2302 is fixedly installed on the output end of the motor 2301. The threaded column 2303 is threadedly installed on the outer side of the threaded rod 2302. The limiting plate 2304 is fixedly installed on the bottom of the threaded column 2303. The advantage is that by setting the lifting assembly 23, the position of the connecting plate 25 can be adjusted to different heights. This can help the robot adjust to different usage situations, thereby increasing the robot's working range and avoiding the need to use support seats 21 of different heights when working at different heights, which would reduce work efficiency.

[0042] Specifically, two identical sets of slide rails 24 are provided, and the two sets of slide rails 24 are symmetrically distributed inside the support base 21. The limiting plate 2304 is slidably connected to the slide rails 24. The advantage is that the design of the limiting plate 2304 and the slide rails 24 being slidably connected can limit the threaded column 2303 when it is raised and lowered, ensuring the stability of the threaded column 2303 when it is raised and lowered, thereby achieving the stability of the robot raising and lowering at the top of the connecting plate 25.

[0043] Working principle: During use, the first base 1 and the second base 2 can be quickly connected by the matching of the slot 6 and the protrusion 5. The first base 1 and the second base 2 can be easily and quickly fixed by the locking screw 8. The detachable design of the first base 1 and the second base 2 allows for the increase of the transportation distance by adding different numbers of bases to meet different working environments, reducing production costs and improving installation efficiency. The groove 4 on the inner top of the first base 1 and the second base 2 facilitates the quick installation of the cable tray inside the first base 1 and the second base 2. The two sets of buckle components 11 can realize the connection between the cable tray 1 and the cable tray 2. The quick connection of 10 is achieved by using a fixed base 1101 with the same cross-section as the slot 2 13. When the fixed base 1101 is inserted into the slot 2 13, the slot 2 13 presses against the locking block 1104. The return spring 1103 drives the locking block 1104 downward until it is inserted into the inside of the fixed base 1101 and into the slot 2 13. At this point, the locking block 1104 matches the top of the inner side of the slot 2 13, the return spring 1103 returns to its original position, and the locking block 1104 pops out, thus locking the fixed base 1101 and preventing it from sliding out of the slot 2 13. The pressing component 12 allows for easy removal of the latching component 11 from the slot 2 13. By designing that the radius of the ring 1204 is larger than the radius of the second return spring 1202 and the radius of the pressing post 1203 is smaller than the radius of the second return spring 1202, when the push-button 1205 is pressed down, the ring 1204 drives the second return spring 1202 to move downward. Then, through the bottom of the pressing post 1203 penetrating the slot 13, it contacts the locking block 1104, which can squeeze the locking block 1104 into the inner side of the fixing seat 1101, thereby realizing the quick disassembly of the cable tray 9 and the cable tray 10. The positioning block 18 on the top of the fixing plate 17 can realize the quick installation of the support seat 21. By setting multiple sets of reinforcing plates 22, the support seat 21 can be increased. The supporting force is improved, and the stability of the device operation is enhanced. By setting the lifting component 23, the position of the connecting plate 25 can be adjusted to different heights, which can help the robot adapt to different usage situations, thereby increasing the robot's working range. This avoids the need to use support seats 21 of different heights when working at different heights, which results in low work efficiency. The limit plate 2304 and the slide rail 24 are designed to slide and connect, which can limit the threaded column 2303 when it is raised and lowered, ensuring the stability of the threaded column 2303 when it is raised and lowered, thereby achieving the stability of the robot's raising and lowering at the top of the connecting plate 25.
