Description

Technical Field

[0001] This invention belongs to the field of battery swapping equipment for new energy heavy-duty trucks, and in particular, a scanning and positioning device for battery packs for new energy heavy-duty trucks. Background Technology

[0002] With the increasing development of the new energy industry and the country's requirements for green energy and energy conservation and environmental protection, vehicles powered by new energy are gradually gaining public recognition, and battery packs for new energy heavy trucks are also being widely used.

[0003] Existing battery swapping technology, due to the limited range of battery pack detection, generally requires drivers to park the vehicle in a very small area to ensure a high success rate of battery swapping. If the vehicle's position is off, the driver needs to move the vehicle repeatedly to meet the parking requirements, which undoubtedly greatly reduces the efficiency of battery swapping. Summary of the Invention

[0004] In view of the above, it is necessary to provide a scanning and positioning device for battery packs of new energy heavy trucks, which can conveniently detect the position of the battery pack in the width and length directions.

[0005] The scanning and positioning device for the battery pack of new energy heavy-duty trucks includes: Fixed base; The first rotating shaft is rotatably connected to the fixed base in the first plane; The second rotating shaft is rotatably connected to the first rotating shaft within a second plane, wherein the first plane is perpendicular to the second plane; A vision camera is connected to the second rotating shaft; the first rotating shaft drives the vision camera to scan in a plane along the length direction of the battery pack via the second rotating shaft, and the second rotating shaft drives the vision camera to scan in a plane along the width direction of the battery pack.

[0006] The scanning and positioning device for the battery pack of the new energy heavy truck also includes a third rotating shaft, which is rotatably connected to the second rotating shaft in the second plane, and the vision camera is connected to the third rotating shaft.

[0007] According to the scanning and positioning device for the battery pack of the new energy heavy truck, the vision camera is connected to the end face of the third rotating shaft.

[0008] According to the scanning and positioning device for the battery pack of the new energy heavy truck, the fixing seat is located at the corner of the battery pack.

[0009] According to the scanning and positioning device for the battery pack of the new energy heavy truck, the height of the bottom surface of the battery pack is equal to the length of the first rotating shaft.

[0010] According to the scanning and positioning device for the battery pack of the new energy heavy truck, the vision camera is a 3D vision camera.

[0011] The scanning and positioning device for the battery pack of the new energy heavy truck further includes a first driving component for driving the first rotating shaft to rotate relative to the fixed seat, the first driving component being located inside the first rotating shaft or the fixed seat.

[0012] The scanning and positioning device for the battery pack of the new energy heavy truck further includes a second driving component for driving the second rotating shaft to rotate relative to the first rotating shaft, the second driving component being located inside the first rotating shaft or the second rotating shaft.

[0013] Compared to existing technologies, the aforementioned scanning and positioning device for the battery pack of new energy heavy-duty trucks rotates in a first plane via a first rotating shaft, causing a vision camera to scan the position of the battery pack along its length in a plane; and rotates in a second plane via a second rotating shaft, causing a vision camera to scan the position of the battery pack along its width in a plane. Through multi-angle scanning and recognition, the device increases the position detection range of the battery pack, reduces the probability of repeated operations by the driver, and improves the success rate and efficiency of battery swapping.

[0019] To better understand the above-mentioned objectives, features, and advantages of this disclosure, the disclosure will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. Many specific details are set forth in the following description to provide a thorough understanding of this disclosure; the described embodiments are merely a part of the embodiments of this disclosure, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this disclosure without inventive effort are within the scope of protection of this disclosure.

[0020] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure belongs. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of this disclosure.

[0021] In various embodiments, for ease of description and not limitation of this disclosure, the term "connection" used in the patent application specification and claims is not limited to physical or mechanical connections, but may include electrical connections, whether direct or indirect. Terms such as "upper," "lower," "below," "left," and "right" are used only to indicate relative positional relationships; when the absolute position of the described object changes, the relative positional relationship also changes accordingly.

[0022] like Figure 1 and Figure 2 As shown, the scanning and positioning device for the battery pack of a new energy heavy-duty truck includes a fixed base 10, a first rotating shaft 20, a second rotating shaft 30, a third rotating shaft 40, and a vision camera 50. The fixed base 10 is used to fix the scanning and positioning device, and the first rotating shaft 20, the second rotating shaft 30, and the third rotating shaft 40 are used to move the vision camera 50 to achieve scanning and positioning of the battery pack 60.

[0023] Specifically, the fixing seat 10 is located at the corner of the battery pack 60, and the height of the bottom surface of the battery pack 60 is equal to the length of the first rotating shaft 20.

[0024] A first rotating shaft 20 is rotatably connected to the fixed base 10 in a first plane, and a second rotating shaft 30 is rotatably connected to the first rotating shaft 20 in a second plane, wherein the first plane is perpendicular to the second plane. A third rotating shaft 40 is rotatably connected to the second rotating shaft 30 in the second plane, and a vision camera 50 is connected to the third rotating shaft 40. Specifically, the vision camera 50 is connected to the end face of the third rotating shaft 40 and is used to adjust the scanning angle of the vision camera 50.

[0025] A vision camera 50 is connected to the second rotating shaft 30; the first rotating shaft 20 drives the vision camera 50 to scan in the plane along the length direction of the battery pack 60 via the second rotating shaft 30, and the second rotating shaft 30 drives the vision camera 50 to scan in the plane along the width direction of the battery pack 60. The vision camera 50 is a 3D vision camera 50.

[0026] To drive the first rotating shaft 20, the second rotating shaft 30, and the third rotating shaft 40 to oscillate, a first drive assembly is located within the first rotating shaft 20 or the fixed base 10, for driving the first rotating shaft 20 to rotate relative to the fixed base 10. A second drive assembly is located within the first rotating shaft 20 or the second rotating shaft 30, for driving the second rotating shaft 30 to rotate relative to the first rotating shaft 20. Similarly, a drive mechanism is also provided within the third rotating shaft 40 for driving the third rotating shaft 40 to rotate relative to the second rotating shaft 30.

[0027] During operation, the mounting base 10 is fixedly installed at a preset position corresponding to the battery pack 60. The first rotating shaft 20 swings in the first plane, and the second rotating shaft 30 remains fixed relative to the first rotating shaft 20. The first rotating shaft 20 drives the vision camera 50 to rotate through the second rotating shaft 30, scanning and detecting the position of the battery pack 60 in the plane along the length direction of the battery pack 60. When the first rotating shaft 20 rotates to the vertical position, the second rotating shaft 30 swings relative to the first rotating shaft 20 in the second plane, driving the vision camera 50 to scan and detect the position of the battery pack 60 in the plane along the width direction of the battery pack 60.

[0028] The aforementioned scanning and positioning device for the battery pack of the new energy heavy-duty truck rotates in a first plane via a first rotating shaft 20, causing the vision camera 50 to scan the position of the battery pack 60 in the length direction of the battery pack 60 in a plane; and rotates in a second plane via a second rotating shaft 30, causing the vision camera 50 to scan the position of the battery pack 60 in the width direction of the battery pack 60 in a plane in the width direction. Through multi-angle scanning and recognition, the position detection range of the battery pack 60 is increased, the probability of repeated operations by the driver is reduced, and the success rate and efficiency of battery swapping are improved.
