Description

Technical Field

[0001] The utility model relates to the technical field of battery replacement, and more specifically, to a battery replacement robot and a battery replacement station. Background Art

[0002] With the increasing maturity of new energy technologies, battery-swappable mining trucks and mining trucks are gradually becoming popular. Existing technologies offer battery-swappable robots specifically designed for mining truck battery swaps, which can be used to replace battery boxes on mining trucks. These robots typically consist of a mobile traveling frame, a telescopic arm assembly, and a lifting device. The traveling frame is movable, the telescopic arm assembly is connected to the traveling frame, and the lifting device is connected to the free end of the telescopic arm assembly. The telescopic arm assembly can only extend and retract in a fixed direction and cannot swing. This type of battery-swappable robot structure places high demands on the parking position of the mining truck. When the driver parks the mining truck at the battery swap station, the relative angle (parallel or perpendicular) between the mining truck and the station must be very precise. This ensures that when the telescopic arm assembly is extended, the lifting device and the battery box on the mining truck align smoothly, allowing the lifting device to connect smoothly to the battery box. This type of battery-swappable robot places high demands on the driver, increases vehicle operation difficulty, and hinders battery swap efficiency. Furthermore, there is little space between the eaves of the mining truck's cargo box and the battery box. If the telescopic arm assembly is too thick, the lifting device used to access the battery box will have a limited lifting distance, affecting loading and unloading performance.

[0054] It should be noted that these drawings and textual descriptions are not intended to limit the conceptual scope of the present invention in any way, but rather to illustrate the concept of the present invention for those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION

[0055] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention but are not used to limit the scope of the present invention.

[0056] In the description of the present invention, it should be noted that the terms "upper", "lower", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or component referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.

[0057] In the description of this utility model, it should be noted that, unless otherwise specified or limited, the terms "mounted" and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; and direct connections or indirect connections through an intermediary. Those skilled in the art will understand the specific meanings of these terms in this utility model based on the specific circumstances.

[0058] See also Figures 1 to 7 As shown, an embodiment of the present application provides a battery-swapping robot 100, comprising: a lifting frame 1, a telescopic arm assembly 2, and a sling 3. The lifting frame 1 comprises an upper frame 11, a lower frame 12, and a lifting mechanism 13. The lifting mechanism 13 is respectively connected to the upper frame 11 and the lower frame 12. The lifting mechanism 13 is telescopic and can drive the upper frame 11 to move up and down relative to the lower frame 12. The telescopic arm assembly 2 is swingably arranged on the upper frame 11, and the swing axis of the telescopic arm assembly 2 is parallel to the lifting direction of the upper frame 11. The sling 3 is connected to the telescopic arm assembly 2. A walking mechanism 4 can be provided on the lower frame 12, which can move along the battery-swapping station and drive the entire battery-swapping robot 100 to move.

[0059] The telescopic arm assembly 2 of the battery-exchanging robot 100 of the present application can swing in the horizontal plane to adjust the angle of the sling 3 so that the angle of the sling 3 matches the angle of the battery box, which facilitates the smooth combination of the sling 3 and the battery box. The lifting frame 1 can move up and down and can lift or lower the battery box connected to the sling 3, facilitating the loading and unloading of the battery box.

[0060] The space between the eaves of a mining truck's cargo box and the battery compartment is small. In the prior art, a hoist or telescopic cylinder is typically installed at the end of a telescopic arm assembly to drive the lifting and lowering motion of the spreader. This thick telescopic arm assembly reduces the lifting distance of the spreader for battery access, impacting loading and unloading performance. The battery-swapping robot 100 provided in this embodiment does not require a hoist or telescopic cylinder at the end of the telescopic arm assembly, resulting in a simple telescopic arm structure and a smaller thickness. This increases the lifting distance of the spreader and improves loading and unloading performance.

[0061] The telescopic arm assembly 2 may include a plurality of movable arms 21 , and adjacent movable arms 21 are slidably connected. The movable arm 21 at one end is movably connected to the upper frame 11 , and the movable arm 21 at the other end is connected to the sling 3 .

[0062] In some possible embodiments, such as Figures 1 to 5 As shown, the telescopic arm assembly 2 includes multiple movable arms 21. Two adjacent movable arms 21 are slidably connected. The movable arm 21 at one end is swingably connected to the upper frame 11, and the movable arm 21 at the other end is connected to the spreader 3. The swing range of the telescopic arm assembly 2 can be limited to between -3° and +3°.

[0063] The telescopic arm assembly 2 can be located at the bottom side of the upper frame 11. The movable arm 21 at one end can swing to drive the entire telescopic arm assembly 2 to swing in the plane in which it is located. A telescopic assembly can be installed between adjacent movable arms 21. The telescopic assembly can drive two adjacent movable arms 21 to slide relative to each other, extending or shortening the length of the entire telescopic arm assembly 2. The telescopic assembly can include a telescopic cylinder and other components. This application does not limit the specific structure and operating principle of the telescopic assembly.

[0064] In some possible implementations, see Figure 1 As shown, the upper frame 11 comprises an upper frame 111 and a lower extension column 112 perpendicularly connected to the upper frame 111. The lower extension column 112 and the lower frame 12 are slidably connected. The upper frame 111 is provided with a rotational engagement portion 1111, which is perpendicular to the upper frame 111. The movable arm 21 at the end is connected to the rotational engagement portion 1111 and can rotate around the rotational engagement portion 1111. The rotational engagement portion 1111 can be a rotating shaft or a fixed shaft extending in the longitudinal direction, and the movable arm 21 at the end is connected to the rotating shaft or fixed shaft.

[0065] In some possible implementations, see Figure 1As shown, the battery-exchanging robot 100 includes a telescopic component 113, the two ends of which are respectively hinged to the upper frame 111 and the movable arm 21 at the end. The telescopic component 113 can telescope and move, and can drive the movable arm 21 at the end to rotate around the rotating mating part 1111.

[0066] In some possible implementations, see Figure 1 As shown, the battery-swapping robot 100 includes at least two telescopic components 113, each of which is connected to a portion of the movable arm 21 at the end located on both sides of the rotating mating portion 1111. The two telescopic components 113 work together to drive the telescopic arm assembly 2 to swing, thereby reducing the load on a single telescopic component 113, increasing reliability and improving the stability of the device.

[0067] In some possible embodiments, combined Figure 1 and Figure 2 As shown, the lifting mechanism 13 includes a lifting component 131, a steering component 132 and a transmission bar 133. One end of the lifting component 131 is connected to the lower frame 12, and the steering component 132 is connected to the other end of the lifting component 131. The transmission bar 133 passes through the steering component 132, and the two ends of the transmission bar 133 are respectively connected to the upper frame 11 and the lower frame 12. The lifting component 131 can move telescopically and can drive the upper frame 11 to move up and down through the transmission bar 133. The lifting component 131 can be a telescopic cylinder, the transmission bar 133 can be a chain, and the steering component 132 can be a pulley. When the lifting component 131 is extended at a speed v, the transmission bar 133 drives the upper frame 11 to rise at a speed of 2v. The range of the upper frame 11 is twice the range of the lifting component 131, thereby significantly improving the battery replacement efficiency.

[0068] In some possible implementations, see Figure 1 and Figure 2 As shown, the lower frame 12 includes a lower frame 121 and an upper extension column 122. The upper extension column 122 is vertically connected to the lower frame 121. The upper frame 11 is slidably connected to the upper extension column 122. The two ends of the transmission bar 133 are respectively connected to the upper extension column 122 and the upper frame 11. The lower frame 121 is far away from the upper frame 111. If the transmission bar 133 is connected to the lower frame 121, a longer transmission bar 133 is required, which increases the cost and makes the overall structure of the battery-swap robot 100 more complicated. The transmission bar 133 of the present application is connected to the upper extension column 122, which can effectively shorten the length of the transmission bar 133 and significantly reduce the cost.

[0069] In some possible implementations, see Figure 1 and Figure 2As shown, a connecting ear 1222 is provided at the middle position of the upper extension column 122 along the length direction, and the transmission bar 133 is connected to the connecting ear 1222 .

[0070] A connecting ear 1222 is provided at the middle of the upper extension column 122 . The height of the connecting ear 1222 is lower than the steering component 132 , so that the transmission bar 133 can fit tightly with the steering component 132 .

[0071] In some possible implementations, see Figure 1 and Figure 2 As shown, the upper frame 11 includes an upper frame 111 and a lower extension column 112 vertically connected to the upper frame 111 , the upper extension column 122 and the lower extension column 112 are slidably connected, and one end of the transmission bar 133 is connected to the upper frame 111 .

[0072] The height of the upper frame 111 is lower than the steering component 132, and both ends of the transmission bar 133 are lower than the steering component 132, so that the transmission bar 133 can be pressed together with the steering component 132, so that when the lifting mechanism 13 moves telescopically, it can effectively drive the upper frame 111 to move up and down.

[0073] In some possible implementations, see Figure 6 As shown, one of the upper extension column 122 and the lower extension column 112 is provided with a guide wheel 1221 , and the other is provided with a guide groove 1121 , and the guide wheel 1221 can be accommodated in the guide groove 1121 .

[0074] The guide groove 1121 extends along the longitudinal direction of the extension column and can cooperate with the guide wheel 1221 to convert sliding friction into rolling friction, thereby significantly reducing the lifting resistance.

[0075] It should be noted that multiple guide wheels 1221 can be set on the upper extension column 122 and the lower extension column 112. During the lifting and lowering movement of the upper frame 11 relative to the lower frame 12, when the distance between the upper frame 11 and the lower frame 12 is small, the guide wheels 1221 can be located in the guide groove 1121. When the distance between the upper frame 11 and the lower frame 12 is large, at least part of the guide wheels 1221 can extend out of the guide groove 1121.

[0076] In some possible implementations, see Figure 2 As shown, a frame shell 134 is provided at the end of the lifting component 131, and the frame shell 134 has a through cavity. The steering component 132 is at least partially located in the through cavity. The steering component 132 is rotatably connected to the frame shell 134, and the transmission bar 133 is provided through the through cavity.

[0077] The frame housing 134 acts as a limiter for the transmission bar 133, limiting the position of the transmission bar 133 and preventing the transmission bar 133 from detaching from the frame housing 134. Specifically, the frame housing 134 includes a bottom plate, a top plate, and two side plates. The bottom plate is connected to the end of the lifting component 131. The top plate and the bottom plate are spaced apart. The two side plates are located on either side of the bottom plate, and the side plates are respectively connected to the bottom plate and the top plate. The steering component 132 is located between the two side plates and is hinged to the two side plates. The transmission bar 133 is located between the rolling surface of the steering component 132 and the top plate. The rolling surface of the steering component 132 can be provided with an annular groove, and the transmission bar 133 can be embedded in the annular groove. The top plate and the steering component 132 cooperate to limit the position of the transmission bar 133, so that the transmission bar 133 remains contained in the annular groove and does not easily detach from the annular groove. The steering component 132 can also be a sprocket, and the transmission bar 132 can be a chain.

[0078] See also Figure 7 As shown, the present application also provides a battery swap station, including: a box shell 200 and a battery swap robot 100, the box shell 200 has a battery cavity and a top opening connected to the battery cavity, and the battery cavity is used to accommodate battery boxes. The box shell 200 can be long and narrow, and the battery boxes are arranged in sequence along the length direction of the box shell 200. The battery swap robot 100 is located on one side of the top opening of the box shell, and the lower frame 12 of the battery swap robot 100 is movably arranged on the box shell 200. The battery swap robot 100 can move along the extension direction of the top opening, so that the battery swap robot 100 can move to different positions of the box shell 200 to facilitate grabbing different battery boxes, and also facilitate unloading the depleted battery packs on the mining truck 300 to different positions in the box shell 200, and also facilitate the selection of different battery boxes in the battery swap station to be loaded on the mining truck.

[0079] The lower frame 12 can be provided with a travel mechanism 4, which can include a hydraulic motor, a reducer, a coupling, a drive shaft, and two travel rollers. The two travel rollers are located on both sides of the front of the lower frame 12, and driven wheels can be located on both sides of the rear of the lower frame 12. The hydraulic motor is connected to the input end of the reducer, and the output end of the reducer is connected to the two drive shafts via two couplings. The two drive shafts are respectively engaged with the travel rollers. The rotation of the hydraulic motor can drive the two travel rollers to rotate, and the travel rollers are supported on the top of the box shell 200.

[0080] When it is necessary to take out the battery box on the mining truck 300, the battery-exchanging robot 100 first moves along the box shell 200 to the position corresponding to the mining truck 300. Then, the upper frame 11 is raised and the telescopic arm assembly 2 is extended, so that the sling 3 is located on the top of the battery box on the mining truck 300. If the sling 3 and the battery box on the mining truck 300 are not aligned, the telescopic component 113 can be controlled to telescopically move, so that the telescopic arm assembly 2 swings and adjusts the angle of the sling 3. Then, the lifting mechanism 13 lowers the upper frame 11, so that the sling 3 can be smoothly combined with the battery box. After grabbing the battery box, the telescopic structure lifts the upper frame 11, and the retraction of the telescopic arm assembly 2 can drive the battery box to move to the top opening of the box shell 200. At this time, the walking mechanism 4 can drive the battery-exchanging robot 100 to move to the corresponding battery space on the box shell 200. Finally, the lifting mechanism 13 lowers the upper frame 11 to successfully load the battery box into the battery cavity.

[0081] When the battery box in the battery swap station needs to be loaded onto the mining truck 300, the telescopic arm assembly 2 of the battery swap robot 100 is in the retracted state, and the lifting mechanism 13 retracts, allowing the upper frame 11 to move toward the battery cavity, facilitating the smooth connection between the sling 3 and the battery pack. Subsequently, the lifting mechanism 13 raises the upper frame 11, allowing the sling 3 to lift the battery box. Then, the telescopic wall assembly extends, driving the battery box to move to the top of the mining truck 300. Finally, the lifting mechanism 13 of the battery swap robot 100 retracts, accurately loading the battery box onto the mining truck 300.

[0082] The above description is merely a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as a preferred embodiment, it is not intended to limit the present invention. Any technician familiar with this patent can make some changes or modifications to equivalent embodiments using the above-mentioned technical content without departing from the scope of the technical solution of the present invention. However, any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the solution of the present invention.
