Description

Technical Field

[0001] This utility model relates to the field of robot battery technology, and in particular to a quick battery replacement mechanism for a concrete leveling robot. Background Technology

[0002] In the construction industry, using concrete floor leveling robots to level and slurry wet concrete through high-frequency vibration can greatly improve construction efficiency and quality. When working on high-rise buildings or in basements, transferring the machine to a charging station after its battery runs out requires significant time and effort. Therefore, replacing the leveling machine's battery is the best option when working on high-rise buildings or in basements. However, currently, battery replacement for these robots still presents many inconveniences.

[0003] The prior art CN223025993U discloses a robot vacuum cleaner battery pack. By setting bolts, the robot vacuum cleaner battery pack can be disassembled, which is convenient for later maintenance or battery replacement. It also has a partition and a limiting plate, which can be used to disassemble, replace or repair the battery body.

[0004] The prior art CN217572973U discloses a quick-change battery device for a composite mobile robot. The battery is easy to install and remove, greatly improving work efficiency. Moreover, the battery connection circuit board has high positioning accuracy, making the use process more stable and preventing loosening.

[0005] Traditional battery installation methods often employ cumbersome structures such as bolt fixing. When the battery is depleted and needs replacement, tools are required for disassembly and installation, making the process complex and time-consuming. This not only causes prolonged robot downtime, affecting construction progress, but also poses safety hazards in the complex environment of construction sites. Furthermore, existing battery replacement structures lack effective positioning and guiding devices, making it easy for the battery to be installed inaccurately, resulting in mismatches between the battery interface and the interface inside the battery compartment. This could affect the electrical connection between the battery and the robot, or even damage related components. Utility Model Content

[0006] The core of this invention lies in solving the problem of inaccurate battery interface matching during battery replacement in existing concrete leveling robots through the cooperation of a screw, connecting rod, and pressure ring. Simultaneously, the linkage design of adjustable-pitch guide wheel sets and follower wheel sets allows the mechanism to flexibly adapt to the rolling guidance of the battery body with support columns.

[0007] To solve the above problems, the present invention adopts the following technical solution.

[0008] A quick battery replacement mechanism for a concrete leveling robot includes a battery compartment with a door mounted on its surface via hinges, and a display screen mounted on the surface of the battery compartment. The interior of the battery compartment is arranged with an L-shaped grid, and symmetrically arranged guide plates are slidably mounted on the surface of the grid. Each guide plate has a set of guide wheels and multiple sets of follower wheels mounted on its adjacent surfaces. The battery body is arranged on the top of the guide wheel set and the follower wheel set. A self-locking elbow clamp is arranged at the end of the guide plate near the door. The surface of the battery body is equipped with a plug tube and a plug block located inside the plug tube. The inside of the battery compartment is equipped with a protective sleeve with an inner diameter the same as the outer diameter of the plug tube and a mating block located inside the protective sleeve. The mating block matches the plug block. A pressure ring is installed on the surface of the protective sleeve. The bottoms of the two guide plates are connected by a connecting rod. A threaded screw is installed on the surface of the connecting rod, which passes through the battery compartment. The tail end of the screw is connected to the surface of the connecting rod by a bearing.

[0009] Furthermore, pull rings are installed on the side surface of the battery body away from the battery compartment and on the top surface, and a support column is installed at the bottom of the battery body, with the vertical projection of the support column located inside the vertical projection of the guide wheel assembly.

[0010] Furthermore, a pressing plate is installed on the surface of the fence above the guide plate, and a buffer pad flush with the battery body is installed on the surface of the fence.

[0011] Furthermore, the guide wheel assembly includes a first sleeve threaded onto the surface of the guide plate, and the first sleeve has internal threads. A connecting bolt is connected to the internal threads of the first sleeve. A connecting plate is sleeved on the surface of the connecting bolt through a bushing. A second wheel is sleeved on the outer surface of the first sleeve through a bushing. A first wheel is sleeved on the surface of the connecting bolt through a bushing. The guide wheel assembly is located at the end of the guide plate near the door. The first wheel and the connecting plate are both located in the smooth area of ​​the connecting bolt surface. The first wheel is located between the connecting plate and the second wheel. Roller one is located between the connecting plate and roller two.

[0012] Furthermore, the follower wheel assembly includes a second sleeve installed inside the guide plate. A connecting rod is slidably connected inside the second sleeve. Roller 1 and Roller 2 are respectively sleeved on the surfaces of the connecting rod and the second sleeve through bushings, and the connecting rod is fixedly inserted through the interior of the connecting plate.

[0013] Furthermore, the diameters of wheel one, wheel two, roller one, and roller two are all the same and their surfaces are all covered with a rubber layer, with the radius of wheel one being greater than the height of the support column.

[0014] Compared with existing technologies, the advantages of this utility model are: (1) This solution uses the cooperation of pressure ring, screw and connecting rod. When replacing the battery body, if the plug and mating block on the surface of the battery body cannot be in a coaxial state, resulting in the inability to plug and energize the battery body, the plug and mating block can be adjusted according to the pressure area shown by the pressure ring to assist the plug and mating block to be plugged in coaxially.

[0015] (2) This scheme uses the adjustable spacing guide wheel group and follow-up wheel group linkage design to enable the mechanism to flexibly adapt to the rolling guidance of the battery body with support column. By rotating the connecting bolt, the gap between the first wheel and the second wheel and the gap between the multiple sets of rollers one and two can be adjusted simultaneously to ensure that the bottom of the battery and the support column pass smoothly.

[0018] The technical solution will now be clearly and completely described with reference to the accompanying drawings in the embodiments of this utility model.

[0019] Example 1: Please see Figures 1-3 A quick battery replacement mechanism for a concrete leveling robot includes a battery compartment 1 with a door mounted on its surface via hinges, and a display screen mounted on the surface of the battery compartment 1. The interior of the battery compartment 1 is arranged with an L-shaped grid, and symmetrically arranged guide plates 4 are slidably mounted on the surface of the grid. Each guide plate 4 has a set of guide wheels 6 and multiple sets of follower wheels 9 mounted on its surfaces that are close to each other. The battery body 3 is arranged on the top of the guide wheel sets 6 and the follower wheels 9. A self-locking elbow clamp 5 is arranged at the end of the guide plate 4 near the door. Pull rings are installed on the side surface and top surface of the battery body 3 away from the battery compartment 1. A pressing plate 2 located above the guide plate 4 is installed on the surface of the grid. A buffer pad 7 flush with the battery body 3 is installed on the surface of the grid.

[0020] Specifically, when replacing the battery body 3, first open the compartment door and release the self-locking elbow clamp 5 (the self-locking elbow clamp 5 is existing technology and will not be described in detail here). Then, pull the pull ring on the side surface of the battery body 3 to roll it away from the inside of the battery compartment 1. Then, place the new battery body 3 at the entrance of the compartment door and push the battery body 3 to move along the surface of the guide plate 4. With the cooperation of the guide wheel set 6 and the follower wheel set 9, it gradually approaches the position of the pressing plate 2.

[0021] The design of the buffer pad 7 can play a buffering role during the battery pack installation process, protect the battery body 3, and extend its service life.

[0022] Example 2: Please see Figures 1-3 and Figures 7-9 The guide wheel assembly 6 includes a first sleeve 64 threadedly fixed to the surface of the guide plate 4, and the first sleeve 64 has internal threads. The internal threads of the first sleeve 64 are connected to a connecting bolt 63. The surface of the connecting bolt 63 is sleeved with a connecting plate 8 through a bushing. The outer surface of the first sleeve 64 is sleeved with a second wheel 62 through a bushing. The surface of the connecting bolt 63 is sleeved with a first wheel 61 through a bushing. The follower wheel assembly 9 includes a second sleeve 94 fixedly installed in the guide plate 4. A connecting rod 93 is slidably connected inside the second sleeve 94. Roller 91 and roller 92 are respectively sleeved on the surfaces of the connecting rod 93 and the second sleeve 94 through bushings. The connecting rod 93 is fixedly inserted through the interior of the connecting plate 8.

[0023] The guide wheel assembly 6 is located at the end of the guide plate 4 near the door. The first wheel 61 and the connecting plate 8 are both located in the smooth area of ​​the connecting bolt 63, and the first wheel 61 is located in the middle of the connecting plate 8 and the second wheel 62. The first roller 91 is located in the middle of the connecting plate 8 and the second roller 92.

[0024] Wheel 61, wheel 62, roller 91 and roller 92 have the same diameter and are all covered with a rubber layer. The radius of wheel 61 is greater than the height of the support column 31.

[0025] A support column 31 is installed at the bottom of the battery body 3, and the vertical projection of the support column 31 is located inside the vertical projection of the guide wheel assembly 6.

[0026] Specifically, when the battery body 3 moves on the surface of the guide wheel assembly 6 and the follower wheel assembly 9, if there is a support column 31 on the surface of the battery body 3, the horizontal distance between the first wheel 61 and the second wheel 62 can be adjusted according to the cross-sectional width of the support column 31. This allows the gap between the first wheel 61 and the second wheel 62, and between the first roller 91 and the second roller 92, to provide clearance for the movement of the support column 31. It also allows the bottom of the battery body 3 to roll smoothly on the surface of the first wheel 61 and the second wheel 62, and between the first roller 91 and the second roller 92, without being affected by the support column 31.

[0027] When adjusting the gap between wheel 61 and wheel 62, the connecting bolt 63 needs to be rotated to move wheel 61 away from wheel 62, thus creating a gap. At the same time, the connecting plate 8 also moves outward synchronously due to the action of the bushing, unaffected by the rotation of the connecting bolt 63. Under the action of the connecting plate 8, the connecting rod 93 slides outward synchronously, thus moving roller 91 away from roller 92, forming a gap with the same gap as between wheel 61 and wheel 62, facilitating the smooth passage of the support column 31.

[0028] Example 3: Please see Figures 3-6 The surface of the battery body 3 is equipped with a plug tube 10 and a plug block 11 located inside the plug tube 10. The inside of the battery compartment 1 is equipped with a protective sleeve 12 with an inner diameter the same as the outer diameter of the plug tube 10 and a mating block 13 located inside the protective sleeve 12. The mating block 13 matches the plug block 11. The surface of the protective sleeve 12 is equipped with a pressure ring 14. The bottoms of the two guide plates 4 are connected by a connecting rod 15. The surface of the connecting rod 15 is equipped with a screw 16 that is threaded through the battery compartment 1. The tail end of the screw 16 is connected to the surface of the connecting rod 15 by a bearing.

[0029] Specifically, if the new battery body 3 is moving towards the buffer pad 7, and the plug block 11 and the mating block 13 are in a coaxial state, the plug tube 10 will smoothly enter the interior of the protective tube 12 and will not be squeezed or impacted by the surface of the pressure ring 14. No adjustment is required at this time.

[0030] When the plug-in block 11 and the mating block 13 are in a non-coaxial state, as the battery body 3 approaches the mating block 13, due to the vertical constraints of the pressing plate 2, the guide wheel group 6 and the follower wheel group 9, the battery body 3 can only have a horizontal matching error, which causes the plug-in tube 10 to be unable to enter the interior of the protective tube 12, thereby squeezing the pressure ring 14 (the pressure ring 14 is made of multiple pressure sensors, which are existing technologies and will not be described in detail here). In this embodiment, the pressure sensors are connected to the display screen to display the area of ​​pressure ring 14 being compressed, so as to facilitate the determination of whether the two guide plates 4 need to be moved to the left or right.

[0031] When the two guide plates 4 are moved left and right to adjust, and the battery body 3 and the plug block 11 on the surface are indirectly adjusted, the screw 16 is rotated to drive the connecting rod 15 to move, so as to achieve the corresponding adjustment until the pressure ring 14 is no longer under pressure, and the battery body 3 is pushed closer to the buffer pad 7.

[0032] The above description is merely a preferred embodiment of this utility model; it encompasses all the protection scope of this utility model. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be covered within the protection scope of this utility model.
