Description

Technical Field

[0001] This utility model relates to the field of mobile robot technology, specifically a mobile robot that can quickly replace its energy device. Background Technology

[0002] A mobile robot is an intelligent device with autonomous or semi-autonomous mobility, typically consisting of a body, a drive module (such as wheeled, tracked, or legged mechanisms), a sensor system (vision, lidar, ultrasonic, etc.), a control system, and an energy module. Through environmental perception and path planning technologies, it can autonomously navigate, avoid obstacles, and perform specific tasks in complex indoor and outdoor environments, such as cargo handling in logistics warehousing, drug delivery in medical settings, and inspection and monitoring of outdoor environments. Its core advantage lies in breaking through the limitations of fixed workstations and combining AI algorithms and IoT technology to achieve flexible operation in dynamic environments. It is widely used in industries such as manufacturing, services, agriculture, and rescue, effectively improving production efficiency, reducing labor costs, and replacing human workers in dangerous or repetitive labor scenarios.

[0003] A search revealed that application number CN201820876075.X discloses a mobile robot with easily replaceable batteries, comprising a vehicle body and a drive mechanism connected to the vehicle body. The vehicle body has a detachable battery structure, including a battery compartment, a battery housed in the battery compartment, and a compartment cover hinged to the battery compartment port. Positioning blocks are provided on the side of the battery. The battery supplying power to the mobile robot is replaceable, and the use of positioning blocks and battery guide blocks speeds up automatic battery replacement, improving work efficiency. Furthermore, the mobile robot has a relatively simple structure and is easy to operate. The mobile robot employs a sealed structure and a pull handle for manual battery removal, which not only protects the mobile robot in harsh working environments and maintains good working condition, increasing operational stability, but also reduces maintenance costs.

[0004] However, when using the aforementioned mobile robots, the mobile robots need to be equipped with devices with large-capacity batteries. The batteries themselves are heavy, have a long insertion and removal stroke, and adopt a fixed plug-in battery compartment design. When replacing the battery, it is necessary to manually open the compartment cover, align the plug, and pull it out horizontally. This is not only time-consuming, but also, due to the difference in height between the human body and the robot, as well as the influence of the human body's center of gravity, the battery is pulled out at a high angle, resulting in plug wear, poor contact, and affecting the stability of power supply.

The entire process does not require complex electronic control programs or manual plugging and unplugging, and can reduce the battery replacement steps and time of mobile robots, avoid damage to the plug caused by manual operation, and improve the stability of power supply during robot operation by pressing the battery with the battery cover and the positioning block.

[0020] This utility model uses a multi-stage gear transmission to efficiently convert the small manual flipping motion of the battery cover into a large rotation of the driven gear E, which in turn drives the rack part of the slide bar to achieve a large stroke movement, reducing the intensity of manual labor. The mounting plate and slide bar can be easily pushed out of the battery compartment, making it convenient to replace the battery.

[0021] This invention, by setting bolts and locking tongues, utilizes the characteristic that bolts can be tightened by hand, allowing the battery cover to be limited or released without tools, preventing the battery cover from flipping over due to vibration or other reasons during the movement of the mobile robot.

[0031] 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.

[0032] Example 1:

[0033] Please see Figures 1 to 6 This utility model provides a technical solution:

[0034] A mobile robot that can quickly swap energy devices includes:

[0035] A mobile robot, comprising a body 1 and a mobile module 2, wherein the mobile module 2 is connected to the underside of the body 1 via a base 3;

[0036] The vehicle body 1 includes an outer shell 4, which contains a control module and a battery compartment 402. A transmission part 403 is provided on both sides of the battery compartment 402, and a support part 404 is provided below the battery compartment 402. A clearance groove 401 is provided on the top of the outer shell 4. The battery cover 5 of the battery compartment 402 is rotatably connected to both ends of the drive shaft 11 at the end of the clearance groove 401 through a rotating part 502.

[0037] An energy swapping component is installed inside the battery compartment 402;

[0038] The opening and closing of the battery cover 5 drives the drive shaft 11 to rotate, which, in conjunction with the energy replacement component, pushes out the battery 6 to replace the mobile robot's energy.

[0039] Specifically, the energy replacement component includes a mounting plate 8, which is fixedly connected between slide bars 9 in the transmission parts 403 on both sides. A positioning block 7 is fixedly connected to the mounting plate 8 for positioning the battery 6.

[0040] Specifically, a push plate 701 is fixedly connected to the end of the mounting plate 8 for pushing out the battery 6. The slide bar 9 is slidably connected in the slide rail 10. The slide rail 10 is fixedly connected to the bottom of the rotating part 502. A rack part 901 is provided at the rear half of the upper end face of the slide bar 9. The rack part 901 meshes with the driven tooth E20.

[0041] In this embodiment, two connecting rods 501 are fixedly connected to the top two sides of the battery cover 5, respectively. The connecting rods 501 are accommodated in the clearance groove 401 opened on the top of the outer casing 4. The end of the clearance groove 401 is rotatably connected to the drive shaft 11. The rotating part 502 at the end of the connecting rod 501 is connected to the drive shaft 11. When it is necessary to change the energy source, the battery cover 5 is opened upward. At this time, the battery cover 5 and the connecting rod 501 are flipped along the rotating part 502. At this time, the rotating part 502 drives the drive shaft 11 to rotate. The drive shaft 11 drives the drive shaft 11 to rotate. The power replacement component drives the mounting tray 8 inside the battery compartment 402 to slide forward, i.e., be pushed out from the front of the battery compartment 402. A positioning block 7 is fixedly connected to the top of the battery compartment 402. The battery 6 is clamped and positioned inside the battery compartment 402 by the positioning block 7. A push plate 701 is fixedly connected to the end of the positioning block 7. When the mounting tray 8 slides out, the push plate 701 moves forward with the mounting tray 8, disconnecting the battery 6 from the electrical connection plug at the bottom of the battery compartment 402, and pushing the battery 6 out of the battery compartment 402 (e.g., Figure 3 Simply lift the handle 601 to remove the battery 6, place the new battery 6 into the positioning block 7, and flip the battery cover 5 downwards. The battery cover 5 drives the energy replacement component to slide the push plate 701 into the battery compartment 402 via the drive shaft 11. The battery cover 5 will press the battery 6 tightly, making the battery 6 and the electrical connection plug at the bottom of the battery compartment 402 firmly connected, thus completing the energy replacement of the mobile robot. The positioning block 7 helps prevent loosening. The whole process does not require complicated electronic control programs or manual plugging and unplugging, reducing the battery replacement steps and time of the mobile robot, avoiding damage to the plug caused by manual operation, and the battery cover 5 presses the battery 6 tightly, which, together with the positioning block 7, improves the stability of power supply during robot operation.

[0042] Specifically, the driven tooth E20 meshes with the driven tooth D16, the driven tooth D16 meshes with the driven tooth C15, the driven tooth C15 and the driven tooth B14 are fixedly connected to the same positioning shaft, the driven tooth B14 meshes with the driven tooth A13, the driven tooth B14 meshes with the driving tooth 12, and the driving tooth 12 is connected to both ends of the driving shaft 11.

[0043] Specifically, the rotating parts 502 in the clearance grooves 401 on both sides of the outer shell 4 are coaxially connected through the drive shaft 11. The rotation of the drive shaft 11 drives the driven gear E20 to rotate, which in turn drives the slide bar 9 to move forward.

[0044] In this embodiment, the energy swapping component includes a mounting plate 8, which is connected between two sliding bars 9. The sliding bars 9 are slidably connected to the slide rail 10. A rack portion 901 is fixedly connected to the upper rear half of the sliding bar 9. The rack portion 901 meshes with the driven gear E20, which is a 16-tooth gear. The driven gear E20 meshes with the driven gear D16, which has the same number of teeth as the driven gear E20, both being 16-tooth gears. The driven gear D16 meshes with the driven gear C15, which has 32 teeth. That is, when the driven gear C15 drives the driven gear D16, the speed doubles, while the speed remains unchanged when the driven gear D16 drives the driven gear E20.

[0045] Driven gear C15 and driven gear B14 are coaxially connected, meaning they rotate at the same speed. Driven gear B14 is a 16-tooth gear. Driven gear B14 meshes with driven gear A13, which is a 36-tooth gear. Driven gear A13 also meshes with driving gear 12, which is a 20-tooth sector gear, meaning only its lower half has teeth. When the battery cover 5 covers the battery compartment 402, the smooth upper half of driving gear 12 faces upwards. According to the gear transmission formula, the driving gear 12... The rotational speed is transmitted 2.5 times from driven tooth A13 to driven tooth B14, and then 5 times from driven tooth C15 and driven tooth D16 to driven tooth E20. That is, when the battery cover 5 is rotated 90°, driven tooth E20 can drive the rack part 901 of slide bar 9 to move 50 teeth. This efficiently converts the small-amplitude manual rotation of battery cover 5 into a large-amplitude rotation of driven tooth E, thereby driving the rack part 901 of slide bar 9 to achieve a large stroke movement, reducing manual labor intensity, and making it easy to push the mounting plate 8 and slide bar 9 out of the battery compartment 402 for easy battery 6 replacement.

[0046] Specifically, the inner wall at the end of the clearance groove 401 will limit the flipping angle of the battery cover 5 (e.g., Figure 3 This allows the battery cover 5 to flip at an angle between 90° and 100°, preventing the mounting plate 8 and slide bar 9 from falling out of the battery compartment 402.

[0047] Specifically, the positioning shaft of the driven gear is rotatably connected to the rotating part 502 inside the housing 4, and the rotating part 502 is separated from the battery compartment 402 by a metal partition.

[0048] Specifically, a magnetic block 405 is fixedly connected inside the support part 404 to magnetically fix the battery cover 5 and prevent the battery cover 5 from flipping over.

[0049] Specifically, after battery 6 is inserted into battery compartment 402, it connects to the electrical connector at the bottom of battery compartment 402 to supply power to the control module and other modules of the mobile robot.

[0050] Example 2:

[0051] Please see Figures 7 to 8 This utility model provides a technical solution:

[0052] Specifically, a groove 19 is provided at the closure between the battery cover 5 and the outer shell 4. A bolt 17 and a locking tongue 18 are provided in the groove 19. The bolt 17 is used to limit the locking tongue 18.

[0053] In this embodiment, a locking component can be added to the closure between the battery cover 5 and the outer shell 4. The locking tongue 18 is rotatably connected to the groove 19 by the bolt 17. The bolt 17 is a hand-tightening bolt with a rubber sleeve on the top, which can be loosened or tightened manually. When the bolt 17 is tightened, it limits the locking tongue 18. The locking tongue 18, together with the magnetic block 405, restricts the battery cover 5 and prevents the battery cover 5 from flipping over due to vibration or other reasons during the movement of the mobile robot. It is convenient to use and increases the stability during the movement.

[0054] In this embodiment, two connecting rods 501 are fixedly connected to the top two sides of the battery cover 5. The connecting rods 501 are accommodated in the clearance groove 401 opened on the top of the outer casing 4. The end of the clearance groove 401 is rotatably connected to the drive shaft 11. The rotating part 502 at the end of the connecting rod 501 is connected to the drive shaft 11. When it is necessary to change the energy source, the battery cover 5 is opened upwards. At this time, the battery cover 5 and the connecting rod 501 are flipped along the rotating part 502. The rotating part 502 drives the drive shaft 11 to rotate. 11. By driving the energy replacement component, the mounting tray 8 inside the battery compartment 402 slides forward, i.e., is pushed out from the front of the battery compartment 402. A positioning block 7 is fixedly connected to the top of the battery compartment 402. The battery 6 is clamped and positioned inside the battery compartment 402 by the positioning block 7. A push plate 701 is fixedly connected to the end of the positioning block 7. When the mounting tray 8 slides out, the push plate 701 moves forward with the mounting tray 8, disconnecting the battery 6 from the electrical connection plug at the bottom of the battery compartment 402, and pushing the battery 6 out of the battery compartment 402 (e.g., ...). Figure 3 Then, lift the handle 601 to remove the battery 6, place the new battery 6 into the positioning block 7, flip the battery cover 5 downward, and the battery cover 5 drives the energy replacement component to slide the push plate 701 into the battery compartment 402 through the active shaft 11. The battery cover 5 will press the battery 6 tightly, so that the battery 6 is tightly connected to the electrical connection plug at the bottom of the battery compartment 402, thus completing the energy replacement of the mobile robot.

[0055] All other parts of this utility model not described herein are the same as existing technologies, or are known technologies, or can be implemented using existing technologies, and will not be described in detail here.

[0056] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
