Description

Technical Field

[0001] This utility model relates to the field of electric vehicle battery charging and swapping technology, specifically to a battery replacement and conveying component. Background Technology

[0002] Electric vehicles, as zero-emission vehicles, are gaining increasing attention and are being widely promoted. One of the most pressing issues with the widespread use of electric vehicles is charging. Currently, the mainstream solution is to use charging stations, but charging speeds are slow and waiting times are long, becoming a major obstacle to the promotion of electric vehicles. To address this efficiency issue, the existing solution is battery swapping, which directly replaces the battery in the electric vehicle, thus improving its range efficiency.

[0003] Currently, the transfer and installation of battery packs in electric vehicles typically involves manually removing low-charge or old battery packs and then installing fully charged or new battery packs. However, this manual method is not only labor-intensive but also inefficient and prone to errors. While automated conveyor systems can quickly replace batteries and reduce labor costs, existing conveyor systems often lack automatic adjustment capabilities. This results in vibrations during transport, causing the batteries to shift to either side of the conveyor belt. Consequently, manual cell alignment is required during transport, leading to low automation and inefficient operation. Utility Model Content

[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0029] Example 1, as Figure 1-7 As shown, a battery replacement conveying assembly includes a mounting base 1, an X-axis slide plate 2, and a Y-axis sliding frame 3. The X-axis slide plate 2 is slidably connected to the mounting base 1 via an X-axis sliding assembly, and the Y-axis sliding frame 3 is slidably connected to the X-axis slide plate 2 via a Y-axis sliding assembly. The front and rear ends of the Y-axis sliding frame 3 are respectively horizontally rotatably connected to a drive shaft 4 and a driven shaft 5 via bearings. Multiple drive wheels 6 are mounted on the drive shaft 4, and multiple driven wheels 7 are mounted on the driven shaft 5. The drive wheels 6 and driven wheels 7 are connected one-to-one by a transmission chain belt 20. One end of the drive shaft 4 is connected to the output shaft of a transmission motor 8, which is fixedly mounted on the Y-axis sliding frame 3.

[0030] A pushing assembly 9 is installed in the Y-axis sliding frame 3. The pushing assembly includes a strip-shaped base plate 901 and a pushing frame 902. The strip-shaped base plate 901 is horizontally fixedly installed in the Y-axis sliding frame 3 along the Y-axis direction. A lead screw motor 903 is fixedly installed at the rear end of the upper surface of the strip-shaped base plate 901. The output shaft of the lead screw motor 903 is connected to a lead screw 904. The lead screw 904 is set along the Y-axis direction, and both ends of the lead screw 904 are mounted on the strip-shaped base plate 901 through bearing seats. The pushing frame 902 is slidably connected to the strip-shaped base plate 901. The middle of the pushing frame 902 is threadedly connected to the lead screw 904 through a lead screw nut 905. The front of the pushing frame 902... A push plate 906 is slidably connected to the side along the Z-axis. A rack 907 is vertically mounted on the rear side of the push plate 903. A drive motor 908 is fixedly mounted on the push frame 902. The output shaft of the drive motor 908 is driven by the gear meshing with the rack 907. A push rod 909 is fixedly mounted on the front side of the push plate 906. A vision recognition camera 22 is mounted at the front end of the Y-axis sliding frame 3. The signal output terminal of the vision recognition camera 22 is connected to the signal input terminal of the controller. The signal output terminal of the controller is connected to the signal input terminals of the X-axis sliding assembly, the Y-axis sliding assembly, the transmission motor 8, the lead screw motor 903, and the drive motor 908, respectively.

[0031] Working principle:

[0032] In use, the mounting base 1 can be directly installed onto a prior art lifting and moving device, which then drives the overall lifting and movement of the mounting base 1 and its components. In the initial state, the pusher 902 is located at the rear end of the strip base plate 901 near the lead screw motor 903, and the push plate 903 is located below the pusher 902 near the strip base plate 901.

[0033] In practice, the empty battery is first removed from the car and placed on the Y-axis sliding frame 3. Then, the controller operates the drive motor 8, which rotates the drive shaft 4 and driven shaft 5. This, in turn, drives the drive chain belt 20 via the drive wheel 6 and driven wheel 7. Through the transmission of the drive chain belt 20, the empty battery on the Y-axis sliding frame 3 is moved along the Y-axis to the middle position above the Y-axis sliding frame 3, avoiding collisions with other equipment during movement and ensuring safety. Subsequently, the lifting and lowering device moves the battery replacement conveyor assembly to the designated position, ensuring that the front end of the upper surface of the Y-axis sliding frame 3 corresponds to the empty space in the battery compartment. Then, the vision recognition camera 22 accurately identifies the corresponding position of the empty space in the battery compartment and transmits the identification signal to the controller. The controller then controls the X-axis sliding assembly and the Y-axis sliding assembly based on the identification signal to achieve precise positioning of the entire Y-axis sliding frame 3, effectively ensuring that the front end of the Y-axis sliding frame 3 is precisely aligned with the empty space in the battery compartment and avoiding installation errors.

[0034] Then, the controller starts the drive motor 908, which, through the meshing of the gear and rack 907 at the output of the drive motor 908, drives the push plate 906 to rise along the Z-axis. Next, the controller controls the lead screw motor 903 to rotate, which in turn rotates the lead screw 904, causing the lead screw nut 905 to move forward along the axial direction of the lead screw 904. This pushes the empty battery forward into the empty space in the battery compartment via the push rod 90 at the front of the push plate 906, ensuring the battery is accurately placed. Finally, the controller reverses the drive motor 908 and the lead screw motor 903, returning the push frame 902 and the push plate 903 to their initial positions.

[0035] This invention first uses a visual recognition camera 22 to accurately locate the empty space in the battery compartment. Then, through the coordinated operation of the X-axis and Y-axis sliding components, the position of the Y-axis sliding bracket 3 is precisely adjusted. Next, the drive motor 908 and the lead screw motor 903 control the lifting and lowering and forward and backward movement of the push plate 906, thereby achieving precise pushing of the battery and ensuring that the battery can be accurately placed into the battery compartment. Through this series of precise and coordinated operations, not only is the efficiency of battery replacement significantly improved, but the complexity and potential risks of manual operation are also greatly reduced. Human error is reduced, and the stability and reliability of the overall workflow are improved.

[0036] Example 2, as Figure 5-6 As shown, as a further preferred embodiment of the first embodiment, the X-axis sliding assembly includes an X-axis lead screw motor 10 and an X-axis lead screw nut 11. The X-axis lead screw motor 10 is fixedly mounted on the mounting base 1. The output shaft of the X-axis lead screw motor 10 is connected to the X-axis lead screw 12 for transmission. The X-axis lead screw 12 is mounted on the mounting base 1 through a bearing seat. The X-axis lead screw nut 11 is fixedly mounted on the lower surface of the X-axis slide plate 2. The X-axis lead screw nut 11 and the X-axis lead screw 12 are threadedly connected to form a lead screw transmission pair. The control port of the X-axis lead screw motor 10 is connected to the signal output terminal of the controller. An X-axis slide rail 13 is fixedly mounted on the mounting base 1 along the X-axis. An X-axis slider 14 is mounted on the lower surface of the X-axis slide plate 2. The X-axis slide plate 2 is slidably connected to the X-axis slide rail 13 through the X-axis slider 14 to form a sliding pair.

[0037] The Y-axis sliding assembly includes a Y-axis lead screw motor 15 and a Y-axis lead screw nut 16. The Y-axis lead screw motor 15 is fixedly mounted on the Y-axis sliding frame 3. The output shaft of the Y-axis lead screw motor 15 is connected to the Y-axis lead screw 17 for transmission. The Y-axis lead screw 17 is mounted on the Y-axis sliding frame 3 through a bearing seat. The Y-axis lead screw nut 16 is fixedly mounted on the X-axis slide plate 2. The Y-axis lead screw nut 16 and the Y-axis lead screw 17 are threadedly connected to form a lead screw transmission pair. The control port of the Y-axis lead screw motor 15 is connected to the signal output terminal of the controller. A Y-axis slide rail 18 is fixedly mounted on the lower surface of the Y-axis sliding frame 3 along the Y-axis. A Y-axis slider 19 is mounted on the upper surface of the X-axis slide plate 2. The X-axis slide plate 2 is slidably connected to the Y-axis slide rail 18 through the Y-axis slider 19 to form a sliding pair.

[0038] Therefore, when controlling the X-axis sliding assembly and the Y-axis sliding assembly, the controller can control the operation of the X-axis lead screw motor 10 and the Y-axis lead screw motor 15 to drive the X-axis lead screw 12 and the Y-axis lead screw 17 to rotate. This, in turn, drives the X-axis lead screw nut 11 and the Y-axis lead screw nut 16 to move axially along the X-axis lead screw 12 and the Y-axis lead screw 17 respectively, thereby achieving precise displacement of the X-axis slide plate 2 and the Y-axis sliding frame 3 in the X-axis and Y-axis directions, thus ensuring precise alignment of the front end of the Y-axis sliding frame 3 with the empty space in the battery compartment. Furthermore, the two sliding pairs formed by the sliding connection between the X-axis slider 14 and the X-axis slide rail 13, and the sliding connection between the Y-axis slider 19 and the Y-axis slide rail 18, effectively enhance the stability and motion accuracy of the X-axis slide plate 2 and the Y-axis sliding frame 3 during movement.

[0039] In Example 3, as a further preferred embodiment of Example 1, a push slide rail 910 is fixedly installed on the upper surface of the strip base plate 901 along the Y-axis direction. The push slide rail 910 is arranged parallel to the lead screw 904. A movable slider 911 is fixedly installed on the lower surface of the push frame 902, and the movable slider 911 is slidably connected to the push slide rail 910. By sliding the movable slider 911 and the push slide rail 910 to form a Y-axis sliding pair, the smooth guiding movement of the push frame 902 on the strip base plate 90 is effectively ensured, further improving the stability of the overall structure.

[0040] In Embodiment Four, as a further preferred embodiment of Embodiment One, a Z-axis slide rail 912 is vertically fixedly installed on the front side of the pusher frame 902, and a Z-axis slider 913 is installed on the rear side of the push plate 906. The push plate 906 is slidably connected to the Z-axis slide rail 912 via the Z-axis slider 913. Therefore, when the gear at the output end of the drive motor 908 rotates to drive the push plate 906 to move up and down along the Z-axis, the sliding action of the Z-axis sliding pair formed by the sliding connection between the Z-axis slider 913 and the Z-axis slide rail 912 effectively ensures the smooth movement of the push plate 906 in the Z-axis direction, ensuring its precise positioning at different heights.

[0041] In Example 5, as a further preferred embodiment of Example 1, a wire encoder 915 is installed on the strip base plate 901, and the wire end of the wire encoder 915 is connected to the push frame 902. The displacement data of the push plate 906 can be monitored in real time through the wire encoder 915, and feedback adjustment can be performed through the controller to ensure the motion accuracy of the push plate 906 in the Z-axis direction.

[0042] In Example 6, as a further preferred embodiment of Example 1, a pressure sensor 916 is installed in the middle of the push rod 909. Specifically, the push rod 909 includes a guide shaft and a top block, and the pressure sensor 916 is installed between the guide shaft and the top block. One end of the guide shaft is fixedly connected to the front end face of the push plate 906. Thus, when the battery is pushed by the push rod 909, the pushing force can be monitored in real time by the pressure sensor 916. When the pushing force exceeds a preset threshold, the controller immediately stops the operation of the lead screw motor 903 to ensure that the battery is safely installed into the battery compartment and to avoid damage caused by excessive pushing force.

[0043] Example 7, as Figure 7 As shown, as a further preferred embodiment, the Y-axis sliding frame 3 is equipped with limit mechanisms 21 at both the front and rear ends. The limit mechanism 21 includes a mounting plate 211 and an electric push rod 212. The mounting plate 211 is fixed to the front and rear ends of the upper surface of the Y-axis sliding frame 3. A rotating seat 213 is installed on the lower surface of the mounting plate 211. One end of the electric push rod 212 is rotatably connected to the rotating seat 213. The other end of the electric push rod 212 is connected to one end of the L-shaped limit block 214 through a rotating shaft. A vertical through hole 215 is opened on the surface of the mounting plate 211. A pin is installed in the through hole 215. The middle of the L-shaped limit block 214 is rotatably connected to the pin. The other end of the L-shaped limit block 214 moves through the through hole 215. The control port of the electric push rod 212 is connected to the signal output terminal of the controller.

[0044] In the initial state, the telescopic shaft of the electric push rod 212 is in the extended state. At this time, the L-shaped limit block 214 is hidden in the strip-shaped through hole 215, which does not hinder the movement of the battery on the Y-axis sliding frame 3.

[0045] When the battery is placed on the Y-axis sliding frame 3 and driven by the transmission motor 8 via the transmission chain 20, it moves to the middle position above the Y-axis sliding frame 3. At this point, the controller can retract the telescopic shaft of the electric push rod 212, causing the lower end of the L-shaped limiting block 214 to rotate. This, through a seesaw principle, causes the L-shaped limiting block 214 to rotate around the pin, resulting in the other end of the L-shaped limiting block 214 tilting upwards. The L-shaped limiting blocks 214 at both ends of the Y-axis sliding frame 3 effectively prevent the battery from slipping off the Y-axis sliding frame 3 due to inertia during movement. When it is necessary to push the battery into the battery compartment, the telescopic shaft of the electric push rod 212 is extended again, causing the L-shaped limiting block 214 to return to its original position, releasing the limiting effect and ensuring the battery smoothly enters the battery compartment.

[0046] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
