Description

Technical Field

[0001] This utility model relates to the field of robot accessories technology, and more specifically, to a foldable service robot chassis. Background Technology

[0002] Service robots are intelligent devices that can assist or replace humans in completing various service tasks. They are widely used in fields such as homes, healthcare, catering, logistics, and public services. They have functions such as environmental perception, autonomous navigation, and human-computer interaction, and can perform diverse tasks such as cleaning, delivery, guidance, and care. Their intelligence and flexibility are constantly improving, which not only improves service efficiency and quality, but also brings more convenience to people's lives and work, becoming an important manifestation of modern technology integrating into daily life.

[0003] A search revealed a robot chassis with publication number CN218452979U. The background section addressed the issue that "most existing robot chassis are only suitable for specific models or sizes of robots, and are usually custom-made for a particular model, resulting in poor applicability." The solution addressed this issue by incorporating a base plate, baffles, guardrails, and side plates. However, in practical use, this technology lacks the ability to be folded and stored, leading to a large storage space occupied by the unassembled robot chassis. This hinders the large-scale storage and transportation of robot chassis, thus requiring improvement. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0022] like Figures 1 to 6 As shown, this utility model provides a foldable service robot chassis, including a first hinge plate 1, a second hinge plate 2 hinged to the left side of the upper surface of the first hinge plate 1, the left surface of the first hinge plate 1 and the right surface of the second hinge plate 2 being movably connected, a first bottom compartment 10 fixedly connected to the lower surface of the first hinge plate 1, a second bottom compartment 11 fixedly connected to the lower surface of the second hinge plate 2, hollow plates 3 fixedly connected to the left sides of the front and rear outer surfaces of the first hinge plate 1, baffles 4 fixedly connected to the upper and lower sides of the outer surface of the hollow plates 3, movable blocks 5 movably connected to the inner surface of the hollow plates 3, the outer surface of the movable blocks 5 being movably connected to the baffles 4, a lever 6 fixedly connected to the left end of the movable blocks 5, and an insert block 7 fixedly connected to the left surface of the lever 6. The left end of the insert 7 passes through the hollow plate 3 and extends to the outside of the hollow plate 3. The outer surface of the insert 7 is movably sleeved with the fixed sleeve blocks 8 located on the front and rear sides of the second hinge plate 2. The fixed sleeve blocks 8 and the outer surface of the second hinge plate 2 are fixedly connected. The right surface of the movable block 5 is fixedly connected with the spring 9. The other end of the spring 9 is fixedly connected to the right side of the inner surface of the hollow plate 3. When the outer surface of the insert 7 can be aligned with the fixed sleeve block 8 and inserted into the inner surface of the fixed sleeve block 8, the upper surfaces of the first hinge plate 1 and the second hinge plate 2 will be on the same plane. When the insert 7 is disengaged from the inner surface of the fixed sleeve block 8, the rotation lock of the second hinge plate 2 as a whole will be released, thereby enabling the first hinge plate 1 and the second hinge plate 2 to be folded and stored.

[0023] Among them, the bottom ends of the inner surfaces of the first bottom compartment 10 and the second bottom compartment 11 are fixedly connected to the fixing plates 28. The lower surfaces of the first hinge plate 1 and the second hinge plate 2 are fixedly connected to the guide rods 29. The bottom ends of the guide rods 29 are fixedly connected to the connecting plates 30. There are four connecting plates 30. The outer surfaces of the four connecting plates 30 are fixedly connected to the inner surfaces of the first bottom compartment 10 and the second bottom compartment 11, respectively. The left side of the front surface of the first bottom compartment 10 is movably fitted with a first self-locking threaded rod 12. The rear end of the first self-locking threaded rod 12 passes through the first bottom compartment 10 and extends to the rear side of the first bottom compartment 10. The outer surface of the first self-locking threaded rod 12 is threaded. A first movable plate 13 is fitted inside the first bottom compartment 10. A first limiting rod 14 is fixedly fitted on the right side of the front surface of the first bottom compartment 10. The rear end of the first limiting rod 14 passes through the first bottom compartment 10 and the first movable plate 13 and extends to the rear side of the first bottom compartment 10. The outer surface of the first limiting rod 14 and the inner surface of the first movable plate 13 are movably fitted. When the operator rotates the first self-locking threaded rod 12, the first movable plate 13 will start to move back and forth under the drive of the thread of the first self-locking threaded rod 12. The design of the first limiting rod 14 plays the role of preventing the first movable plate 13 from rotating during the movement.

[0024] Among them, the outer surfaces of the left and right sides of the first moving plate 13 are hinged to the first connecting rod 15, and the other end of the first connecting rod 15 is hinged to the first mounting plate 16. The inner surface of the first mounting plate 16 and the outer surface of the guide rod 29 are movably connected. When the first moving plate 13 starts to move back and forth, the first connecting rod 15 will rotate with the movement of the first moving plate 13. At the same time, the other end of the first connecting rod 15 will drive the first mounting plate 16, thereby causing the first mounting plate 16 to start to move up and down along the outer surface of the guide rod 29.

[0025] Among them, a No. 1 motor 17 is fixedly installed in the middle of the lower surface of the No. 1 mounting plate 16. The other end of the output shaft of the No. 1 motor 17 is fixedly sleeved with a No. 1 round shaft 18. There are two No. 1 round shafts 18. Steering wheels 19 are fixedly installed on the outer surface of the two No. 1 round shafts 18. When the No. 1 motor 17 starts, the No. 1 round shaft 18 and the steering wheel 19 will start to rotate. When the steering wheel 19 contacts the ground, the No. 1 hinge plate 1 will start to move on the ground under the drive of the steering wheel 19.

[0026] The second self-locking threaded rod 20 is movably sleeved on the right side of the front surface of the second bottom compartment 11. The rear end of the second self-locking threaded rod 20 passes through the second bottom compartment 11 and extends to the rear side of the second bottom compartment 11. The outer surface of the second self-locking threaded rod 20 is threadedly sleeved with the second moving plate 21 located inside the second bottom compartment 11. The left side of the front surface of the second bottom compartment 11 is fixedly sleeved with the second limiting rod 22. The rear end of the second limiting rod 22 passes through the second bottom compartment 11 and the second moving plate 21 in sequence and extends to the rear side of the second bottom compartment 11. The outer surface of the second limiting rod 22 and the inner surface of the second moving plate 21 are movably sleeved. When the operator rotates the second self-locking threaded rod 20, the second moving plate 21 will start to move back and forth under the drive of the thread of the second self-locking threaded rod 20. The design of the second limiting rod 22 is to prevent the second moving plate 21 from rotating during the movement.

[0027] The second movable plate 21 has a second connecting rod 23 hinged to the outer surfaces of both sides. The other end of the second connecting rod 23 is hinged to a second mounting plate 24. The inner surface of the second mounting plate 24 and the outer surface of the guide rod 29 are movably connected. When the second movable plate 21 starts to move back and forth, the second connecting rod 23 will rotate as the second movable plate 21 moves. At the same time, the other end of the second connecting rod 23 will drive the second mounting plate 24, thereby causing the second mounting plate 24 to start to move up and down along the outer surface of the guide rod 29.

[0028] Among them, a second motor 25 is fixedly installed in the middle of the lower surface of the second mounting plate 24. The other end of the output shaft of the second motor 25 is fixedly sleeved with a second round shaft 26. A drive wheel 27 is movably installed at the bottom end of the second round shaft 26. When the operator starts the second motor 25, the second round shaft 26 and the drive wheel 27 will start to rotate. When both the steering wheel 19 and the drive wheel 27 are in contact with the ground, the rotation of the drive wheel 27 will play a role in steering the overall movement direction of the first hinge plate 1. In addition, the drive wheel 27 and the steering wheel 19 have the same horizontal height and size.

[0029] Working principle and usage process of this utility model:

[0030] First, the operator rotates the No. 1 self-locking threaded rod 12 and the No. 2 self-locking threaded rod 20. The rotation of the No. 1 self-locking threaded rod 12 and the No. 2 self-locking threaded rod 20 will cause the No. 1 moving plate 13 and the No. 2 moving plate 21 to move forward. The movement of the No. 1 moving plate 13 and the No. 2 moving plate 21 will cause the No. 1 connecting rod 15 and the No. 2 connecting rod 23 to drive the No. 1 mounting plate 16 and the No. 2 mounting plate 24 respectively. As a result, the No. 1 mounting plate 16 and the No. 2 mounting plate 24 will move upward and eventually be completely stored inside the No. 1 bottom compartment 10 or the No. 2 bottom compartment 11.

[0031] Then, the operator pulls the lever 6 to disengage the insert 7 from the inner surface of the fixed sleeve block 8. At this time, the rotational lock of the insert 7 and the fixed sleeve block 8 on the second hinge plate 2 is released. The operator can then rotate the second hinge plate 2 to fold it above the first hinge plate 1. The folded first hinge plate 1 and the second hinge plate 2 are easier for the operator to handle, thus facilitating the movement and storage of the first hinge plate 1 and the second hinge plate 2.
