[0039] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0040] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present application. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, they indicate the presence of features, steps, operations, devices, components and / or combinations thereof.

[0041] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that the terms used in this way are interchangeable where appropriate, so that the embodiments of the present application described herein can, for example, be implemented in an order other than those illustrated or described herein.

[0042] Now, exemplary embodiments according to the present application will be described in more detail with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in a variety of different forms and should not be interpreted as being limited to the embodiments described herein. It should be understood that these embodiments are provided to make the disclosure of this application thorough and complete, and to fully convey the concepts of these exemplary embodiments to those of ordinary skill in the art. In the accompanying drawings, for the sake of clarity, the thickness of layers and regions may be exaggerated, and the same reference numerals are used to represent the same devices, and thus their descriptions will be omitted.

[0043] It should be noted that the existing technology has the following technical problems:

[0044] 1) Difficulty in translation: The weight of a power battery pack is usually between several hundred and thousands of kilograms and its volume is relatively large. This makes the assembly process very difficult, especially when translation is required in a limited space, and is prone to problems such as inaccurate positioning or operational errors.

[0045] 2) Difficulty in alignment: The locking pins on the left and right sides of the power battery pack must be precisely aligned with the lock body on the power battery pack frame at the bottom of the frame. Due to the large number of assembly points (such as 16 alignment points along the longitudinal and transverse beams of the frame), manual alignment is time-consuming and difficult to ensure accuracy.

[0046] 3) Insufficient height adjustment accuracy: After the lock pin on the power battery pack rises to the notch in the lock body and contacts the lock tongue, the lifting and lowering needs to be stopped immediately to avoid excessive contact or collision between the lock pin and the lock body. However, traditional methods often make it difficult to achieve precise control of the lifting height of the lock pin at different positions, leading to safety hazards during the assembly process.

[0047] 4) Difficulty in applying force: After the lock pin and the lock body are initially aligned, the power battery pack needs to be moved forward a certain distance (e.g., 15 mm) along the longitudinal beam of the frame to lock and fix the power battery pack. At this time, a large force (e.g., 8000 N) needs to be applied to the power battery pack to overcome the frictional resistance between the lock pin and the locking mechanism. However, due to the weight and volume of the power battery pack, this operation is difficult to implement in the existing technology and is likely to damage the equipment or the battery pack itself.

[0048] Combine Figures 1 to 5 In a specific embodiment of the present invention, a mounting device for a vehicle-mounted battery is provided.

[0049] Specifically, the installation device of the vehicle-mounted battery includes a base assembly 10, an information acquisition assembly 20 and a control assembly 30. The base assembly 10 is movably arranged in the horizontal direction and telescopically arranged in the vertical direction. The base assembly 10 is used to connect the battery pack 50; the information acquisition assembly 20 is connected to the base assembly 10, and the information acquisition assembly 20 is used to obtain basic information of the battery pack 50 and the battery pack frame 60. The basic information includes at least one of the following: position information and image information; the control assembly 30 is connected to the base assembly 10, and the base assembly 10 and the information acquisition assembly 20 are both electrically connected to the control assembly 30; wherein, the information acquisition assembly 20 obtains the basic information of the battery pack 50 and the battery pack frame 60, and the control assembly 30 controls the movement of the base assembly 10 based on the basic information to install the battery pack 50 to the battery pack frame 60.

[0050] In this embodiment, since the base assembly 10 can be movably arranged in the horizontal direction and telescopically arranged in the vertical direction, the position of the battery pack 50 can be quickly adjusted, which shortens the positioning and alignment time during the assembly process, greatly improves the installation efficiency of the battery pack, reduces manual intervention, and speeds up the production line. The information acquisition assembly 20 can provide accurate coordinate data and visual feedback by acquiring real-time position information and image information of the battery pack 50 and the battery pack frame 60, so that the control assembly 30 can accurately control the movement of the base assembly 10 based on this basic information, ensuring perfect docking of the battery pack with the bottom frame of the frame, and avoiding errors that may be caused by traditional manual installation. The automated installation process reduces the opportunity for people to directly contact heavy objects, reduces the labor intensity of workers and the risk of safety accidents. At the same time, the high-precision detection function of the information acquisition assembly 20 can promptly detect potential installation errors or collision risks, further ensuring the safety of the installation process.

[0051] By applying the technical solution of the present invention, the base assembly 10 can be movably arranged in the horizontal direction and telescopically arranged in the vertical direction, so that the position of the battery pack 50 can be quickly adjusted. The information acquisition assembly 20 obtains at least one of the real-time position information and image information of the battery pack 50 and the battery pack frame 60, so that the control assembly 30 can accurately control the movement of the base assembly 10 based on these basic information, ensuring the perfect docking of the battery pack with the bottom frame of the frame, avoiding the errors that may be caused by traditional manual installation, shortening the positioning and alignment time during the assembly process, greatly improving the installation efficiency of the battery pack, and solving the problem of low assembly efficiency of vehicle-mounted batteries in the prior art.

[0052] Furthermore, the base assembly 10 includes a base body 100, a lifting sub-assembly 11 and a translation sub-assembly 12. The base body 100 is movably arranged in the horizontal direction, the information acquisition assembly 20 is connected to the base body 100, and the base body 100 is electrically connected to the control assembly 30; the lifting sub-assembly 11 is connected to the base body 100, the lifting sub-assembly 11 is telescopically arranged relative to the base body 100 in the vertical direction, and the lifting sub-assembly 11 is electrically connected to the control assembly 30; the translation sub-assembly 12 is connected to the lifting sub-assembly 11, the translation sub-assembly 12 is movably arranged in the horizontal direction relative to the lifting sub-assembly 11, and the translation sub-assembly 12 is electrically connected to the control assembly 30, and the translation sub-assembly 12 is used to connect the battery pack 50; wherein, the control assembly 30 controls the movement of the base body 100, and the control assembly 30 controls the lifting sub-assembly 11 to telescope in the vertical direction, and the control assembly 30 controls the translation sub-assembly 12 to drive the battery pack 50 to be installed on the battery pack frame 60.

[0053] In this embodiment, the horizontal mobility of the base body 100, combined with the vertical telescopic capabilities of the lifting subassembly 11 and the precise horizontal positioning of the translation subassembly 12, allows the device to easily accommodate battery pack frames 60 of varying heights and positions. Together, they enable precise adjustment of the battery pack 50 in three dimensions, ensuring perfect alignment with the battery pack frame 60 and improving installation accuracy and efficiency. Because the base body 100, lifting subassembly 11, and translation subassembly 12 are each electrically connected to the control assembly 30, fine-tuning in different directions can be performed simultaneously or sequentially, shortening adjustment time, improving response speed, and further expediting the battery pack installation process.

[0054] Furthermore, the base assembly 10 also includes a universal wheel 101, a drive motor and an angle sensor. The universal wheel 101 is connected to the base body 100, and the drive motor and the angle sensor are electrically connected to the control assembly 30 respectively. The use of the universal wheel 101 gives the base body 100 the ability to move in all directions on the horizontal plane. It can not only move in a straight line, but also achieve turning and curve movement, thereby enhancing the adaptability of the system in complex assembly environments. This provides great convenience for installing the battery pack 50 in a limited space, especially when it is necessary to bypass obstacles or perform fine-tuning alignment. The addition of the angle sensor enables the system to monitor the rotation angle of the base body 100 in real time, which provides key data support for keeping the battery pack level or adjusting its tilt angle during movement. The control assembly 30 can adjust the working status of the drive motor in a timely manner based on the feedback information from the angle sensor to ensure that the moving direction and angle of the base body 100 meet the installation requirements, thereby avoiding installation failures caused by angle deviation. The addition of the angle sensor enables the system to monitor the rotation angle of the base body 100 in real time, providing critical data for maintaining the battery pack's levelness or adjusting its tilt during movement. Based on the feedback from the angle sensor, the control component 30 can promptly adjust the operating state of the drive motor to ensure that the movement direction and angle of the base body 100 meet installation requirements, thus avoiding installation failures caused by angular deviation.

[0055] Furthermore, the translation subassembly 12 includes a connecting platform 121 and a driving motor 122. The connecting platform 121 is movably connected to the top of the lifting subassembly 11. The connecting platform 121 is movably arranged along the length direction of the base body 100, and the connecting platform 121 is movably arranged along the width direction of the base body 100. The connecting platform 121 is used to connect the battery pack 50; the output end of the driving motor 122 is connected to the connecting platform 121 to drive the connecting platform 121 to reciprocate along the length direction of the base body 100, and drive the connecting platform 121 to reciprocate along the width direction of the base body 100.

[0056] Combine Figure 1 As shown, the connecting platform 121 is capable of precise reciprocating movement in the length and width directions of the base body 100, that is, the position of the battery pack 50 can be freely adjusted on the X-axis and Y-axis, and the battery pack can be quickly and accurately positioned regardless of whether it is arranged in a straight line on the assembly line or in a complex layout that requires crossing obstacles. The design of the translation subassembly 12, especially the combination of the connecting platform 121 and the drive motor 122, provides a powerful translation function for the vehicle-mounted battery installation system, ensuring the precise positioning and smooth movement of the battery pack during the assembly process, and is a key component for the efficient, accurate and safe operation of the system. Under the precise control of the controller 31, the drive motor 122 can provide a force of up to 8000N to push the connecting platform 121 to move, thereby pushing the locking pin 51 on the battery pack 50 into the interior of the lock body 61 to achieve locking and fixation.

[0057] Combine Figure 3 As shown, in this embodiment, the connecting platform 121 is provided with a support block 1211 and a positioning pin 1212. Before assembly begins, the battery pack 50 is hoisted onto the connecting platform 121, and the positioning pin 1212 passes through the positioning hole on the battery pack 50 so that the battery pack 50 can be installed through the installation device.

[0058] Furthermore, the connecting platform 121 and the lifting subassembly 11 are connected via a slide rail 123 and a slider 124 . The slide rail 123 is disposed on one of the connecting platform 121 and the lifting subassembly 11 , and the slider 124 is disposed on the other of the connecting platform 121 and the lifting subassembly 11 .

[0059] In this embodiment, the coordinated use of the slide rails 123 and sliders 124 ensures that the connection platform 121 moves along a predetermined trajectory on the base body 100. This precise guiding mechanism helps improve the horizontal movement accuracy of the battery pack 50 and ensures accurate alignment between the battery pack and the battery pack frame 60. The relatively small contact area between the slide rails 123 and sliders 124 reduces friction during movement, enabling the drive motor 122 to achieve smoother and faster movement with less force when driving the connection platform 121, thereby improving the system's energy efficiency and reducing energy consumption.

[0060] Combine Figure 1 and Figure 2As shown, in another embodiment of the present application, there are multiple groups of slide rails 123 and sliders 124. One slide rail 123 can correspond to one or more sliders 124. Some of the slide rails 123 in the multiple groups of slide rails 123 are arranged at intervals along the length direction of the connecting platform 121, and another part of the slide rails 123 in the multiple groups of slide rails 123 are arranged at intervals along the width direction of the connecting platform 121. The arrangement of the slide rails 123 and sliders 124 not only realizes the translation of the battery pack on the base body 100, but also provides the possibility of multi-directional movement of the battery pack. In some complex assembly scenarios, this flexibility can help the system cope with various possible obstacles and space limitations, ensuring that the battery pack can be smoothly installed in the designated position.

[0061] In a specific embodiment of the present application, the lifting subassembly 11 includes a lifting rod 111, a lifting platform 112 and a lifting motor. One end of the lifting rod 111 is connected to the base body 100, and the other end of the lifting rod 111 is movably arranged relative to the base body 100 along the height direction of the base body 100. The slide rail 123 is arranged on the connecting platform 121, and the slider 124 is arranged on the lifting platform 112.

[0062] Specifically, the lifting rod 111 serves as the main component of the lifting subassembly 11, one end of which is connected to the base body 100, and the other end can move along the height direction of the base body 100. The lifting motor is responsible for driving the lifting rod 111 to move up and down. This design makes the lifting action of the battery pack in the vertical direction more precise, and can adjust the position of the battery pack according to the actual height of the battery pack frame 60 to achieve vertical alignment. The slide rail 123 is fixed on the connecting platform 121, and the slider 124 is provided on the lifting platform 112. This design ensures the stability and guidance of the connecting platform 121 during the translation process. The lifting platform 112 serves as a support for the connecting platform 121. Through the lifting and lowering adjustment of the lifting rod 111, it can provide stable support for the connecting platform 121 in the vertical direction, thereby improving the overall stability of the translation subassembly 12.

[0063] Furthermore, the information acquisition component 20 includes a camera 21 and a laser radar. The camera 21 is connected to the base body 100 and is electrically connected to the control component 30. The camera 21 is used to obtain image information of the battery pack 50 and image information of the battery pack frame 60. The laser radar is connected to the base body 100 and is electrically connected to the control component 30. The laser radar is used to obtain position information of the battery pack 50 and position information of the battery pack frame 60.

[0064] In this embodiment, the addition of camera 21 enables the system to capture real-time image information of the battery pack 50 and battery pack frame 60. This image information is crucial for building a three-dimensional model of the battery pack and frame. Using image processing technology, the control component 30 can identify the shape, size, and relative position of the battery pack and frame, providing the foundational data for subsequent precise alignment and translation. LiDAR, a high-precision ranging sensor, can measure and capture the relative position of the battery pack 50 and battery pack frame 60 in real time. The use of LiDAR, particularly when combined with the information from camera 21, enables more precise positioning during battery pack installation, enabling real-time adjustments to translation and lifting movements to ensure alignment between the battery pack and frame mounting points. The camera 21 and LiDAR not only capture information about the battery pack and frame, but also sense the surrounding environment, including detecting obstacles or anomalies on the assembly line. This is crucial for ensuring safe operation of the system in complex environments. Based on this environmental perception, the control component 30 can adjust the battery pack's movement path in real time to avoid collision risks. Through the collaboration of the camera 21 and the lidar, the information acquisition component 20 provides the vehicle-mounted battery installation system with comprehensive, real-time, and accurate environmental and object information, enhancing the intelligence and automation level of the system and improving the efficiency, accuracy, and safety of battery pack installation.

[0065] Furthermore, the installation device includes a verification subassembly 40, which includes: a target part 41, which is electrically connected to the control assembly 30, and is used to connect to the locking pin 51 of the battery pack 50, and is used to send a signal; a detection part 42, which is electrically connected to the control assembly 30, and is used to connect to the lock body 61 of the battery pack frame 60, and is arranged in coordination with the target part 41, and is used to detect the signal sent by the target part 41; a capacitive force sensor 43, and the capacitive force sensor 43 is used to detect the force between the battery pack 50 and the battery pack frame 60.

[0066] Combine Figure 4 and Figure 5 As shown, the target part 41 is installed on the lock pin 51 of the battery pack 50 and can send a specific signal, while the detection part 42 is installed on the lock body 61 of the battery pack frame 60 to receive and detect the signal sent by the target part 41. This signal interaction mechanism can confirm in real time whether the lock pin 51 and the lock body 61 are correctly docked, and provides important feedback on the installation status of the battery pack to the control component 30, ensuring the accuracy and reliability of the installation process. When the lock pin 51 is aligned with the lock body 61, the lifting subassembly 11 is controlled to drive the translation subassembly 12 to lift and lower until the translation subassembly 12 drives the battery pack 50 to move to the pre-installation position. At this time, the translation subassembly 12 is controlled to move along the width direction of the base body 100 (such as Figure 5The battery pack 50 is then moved (as shown) to install it on the battery pack frame 60. The capacitive force sensor 43 enables real-time monitoring of the force acting between the battery pack 50 and the battery pack frame 60. This real-time force monitoring is crucial for preventing damage to the battery pack or frame due to excessive external force during installation. It also assists the control assembly 30 in determining whether the battery pack has been properly locked, avoiding safety hazards caused by incomplete locking.

[0067] Through the coordinated work of the target part 41, the detection part 42 and the capacitive force sensor 43, the verification subassembly 40 provides an intelligent installation status monitoring and verification solution for the vehicle-mounted battery installation system, ensuring the accurate, safe and efficient installation of the battery pack, which is an important guarantee for the system to successfully realize its functions.

[0068] In one embodiment of the present application, the target element 41 is a photoelectric emitter and the detection element 42 is a photoelectric sensor. The application of this photoelectric sensing technology provides the verification subassembly 40 of the vehicle-mounted battery installation system with a more accurate and rapid detection capability of the connection status between the lock pin 51 and the lock body 61.

[0069] In a specific embodiment of the present application, target component 41 is a laser emitter, and detection component 42 is a laser alignment sensor. By using a laser emitter as target component 41 and a laser alignment sensor as detection component 42, the verification subassembly 40 in this embodiment can achieve real-time, accurate, and safe verification of the battery pack installation status. This high-precision alignment confirmation and signal feedback mechanism improves the efficiency and reliability of battery pack installation.

[0070] Furthermore, the control component 30 includes a controller 31 and a display screen 32. The controller 31 is electrically connected to the base component 10 and the information acquisition component 20. The display screen 32 is electrically connected to the controller 31 and is used to display basic information.

[0071] In this embodiment, the controller 31 is electrically connected to multiple actuator components, including the base assembly 10, the translation subassembly 12, the lifting subassembly 11, and the verification subassembly 40, to receive and process data and signals from each component. Using advanced control algorithms, the controller 31 analyzes the position, locking status, and force applied between the battery pack 50 and the battery pack frame 60 in real time. Based on this information, it makes precise control decisions, such as adjusting the speed and distance of translation or lifting, and controlling the magnitude and direction of applied force, ensuring the efficiency, accuracy, and safety of the entire installation process. The display screen 32 is electrically connected to the controller 31, providing an intuitive user interface for the operator. It not only displays basic information such as the battery pack model, weight, and dimensions, but more importantly, it presents important information in real time, including the battery pack installation status, system operating parameters (such as motor current and hydraulic pressure), and potential fault warnings. This visual presentation simplifies the operator's understanding and monitoring process, improving the efficiency and comfort of human-machine interaction. By monitoring data from various system components, the controller 31 can quickly identify any potential faults or abnormalities and issue warning signals on the display screen 32. This real-time fault diagnosis and early warning capability helps operators take preventive measures in advance, reducing downtime and maintenance costs, while ensuring the continuity and stability of system operations.

[0072] Through the coordinated operation of the controller 31 and the display screen 32, the control component 30 not only becomes the brain of the vehicle-mounted battery installation system, but also provides operators with powerful decision-making support, monitoring tools and a user-friendly operating experience, further enhancing the overall intelligence and automation level of the system and ensuring high-quality and efficient battery assembly for new energy commercial vehicles.

[0073] In a specific embodiment of the present application, the control component 30 also includes an operation button 33, which is electrically connected to the controller 31, and the operation button 33 is used to control the movement of the base component 10. The operation button 33 provides a manual control mode for the system, allowing the operator to directly control the movement of the base component 10, such as basic actions such as forward, backward, left or right. This is particularly important when the automation system fails or needs fine-tuning. The operator can perform precise manual intervention through the operation button 33 to ensure that the installation position of the battery pack 50 is accurate. The operation button 33 may also be used to switch the operating mode of the system, such as switching from automatic mode to manual mode, or selecting a specific preset operating program. This mode switching function increases the flexibility of the system, allowing the operator to select the most suitable operating method according to actual work requirements and environmental conditions.

[0074] In another embodiment of the present invention, a method for installing a vehicle-mounted battery is provided, which is used to control the installation device for the vehicle-mounted battery in the above embodiment, and includes the following steps:

[0075] Step S102 : acquiring image information of the battery pack and image information of the battery pack frame.

[0076] Step S104 : determining the position information of the battery pack and the position information of the battery pack frame based on the image information of the battery pack and the image information of the battery pack frame.

[0077] Step S106 : determining an installation path of the installation device based on the position information of the battery pack and the position information of the battery pack frame.

[0078] Step S108 : Based on the installation path, control the base assembly of the installation device to install the battery pack on the battery pack frame.

[0079] In step S102, a high-precision 3D camera or other image acquisition device captures images of the battery pack 50 and battery pack frame 60. This step utilizes computer vision technology to capture key information such as the three-dimensional shape, size, surface features, and relative position of the battery pack and frame.

[0080] In step S104, the captured image information is then transmitted to the controller 31 within the control assembly 30. Using built-in image processing algorithms, the controller analyzes and interprets the image data to generate precise positional information for the battery pack 50 and battery pack frame 60. The image processing techniques involved may include feature recognition, edge detection, and matching algorithms, which are used to extract necessary positioning cues from the image, laying the foundation for subsequent path planning.

[0081] In step S106, path planning is performed based on the battery pack and frame position information calculated by controller 31. Controller 31 analyzes the difference between the battery pack's current position and the target installation location, and automatically generates an optimal installation path based on the battery pack's size and weight and the frame's structural characteristics.

[0082] In step S108, controller 31 issues control instructions to base assembly 10 based on the planned installation path, precisely controlling the movements of base body 100, lifting subassembly 11, and translation subassembly 12, guiding battery pack 50 along the path until it is properly installed on battery pack frame 60. Throughout the movement process, control assembly 30 continuously monitors the position and status of the battery pack to ensure accurate installation without accidental collision or deviation.

[0083] Through steps S102-S108, a highly intelligent vehicle-mounted battery installation method is provided. This method integrates image processing technology, path planning algorithms, and automated control methods to automate the entire process, from battery pack positioning to precise installation. This significantly improves the efficiency, accuracy, and safety of battery assembly for new energy commercial vehicles. This installation method is particularly suitable for standardized assembly of large numbers of battery packs, significantly reducing manual operation time and errors, and improving installation efficiency.

[0084] Optionally, determining an installation path of the installation device based on the position information of the battery pack and the position information of the battery pack frame includes:

[0085] Step S201, the position information includes: horizontal position information and height position information;

[0086] Step S202, determining a first target position of a base assembly of the mounting device based on the horizontal position information of the battery pack and the horizontal position information of the battery pack frame;

[0087] Step S203, determining a second target position of the base assembly based on the height position information of the battery pack and the height position information of the battery pack frame;

[0088] Step S204 : determining an installation path of the installation device based on the position information of the battery pack, the first target position, the second target position, and the position information of the battery pack frame.

[0089] In step S201, obtaining position information includes obtaining the horizontal position information and height position information of the battery pack, and the horizontal position information and height position information of the frame. The horizontal position information refers to the position coordinates of the battery pack 50 and the battery pack frame 60 on the X-axis and Y-axis (i.e., the front-back and left-right directions), which is used to determine the planar position deviation of the battery pack relative to the frame. The height position information is the position coordinates of the battery pack on the Z-axis (i.e., the up-down direction), which is used to determine whether the vertical height of the battery pack is appropriate to ensure that the lock pin 51 can smoothly enter the lock body 61.

[0090] In step S202, based on the horizontal position information of the battery pack and the horizontal position information of the battery pack frame, the controller 31 calculates the first target position that the base assembly 10 needs to reach, that is, the position where the battery pack 50 is aligned with the battery pack frame 60 on the X-axis and Y-axis, ensuring the basis for accurate alignment of the battery pack with the frame on the plane, and providing a plane reference point for subsequent installation operations.

[0091] In step S203, after obtaining the horizontal position information of the battery pack and the frame, the controller 31 then determines the second target position of the base assembly 10 based on their height position information, that is, the position on the Z-axis to ensure that the locking pin 51 can smoothly contact and enter the lock body 61, so as to achieve precise assembly of the battery pack in the vertical direction and ensure that the locking mechanism can work effectively.

[0092] In step S204, the controller 31 automatically generates a complete installation path based on the battery pack's location information, the first target location, the second target location, and the location of the battery pack frame. This path not only includes the specific route and sequence for translation and lifting, but also may include the triggering conditions for locking and unlocking operations, as well as the speed and acceleration control strategy during movement, ensuring the entire installation process is efficient, safe, and orderly.

[0093] Through steps S201-S204, the positional information of the battery pack 50 and battery pack frame 60 is refined and applied to intelligent installation path planning, achieving precise and automated vehicle-mounted battery installation. This method not only improves installation efficiency and reduces human error, but also provides new ideas and technical support for the automated battery assembly process in the new energy vehicle manufacturing industry.

[0094] Optionally, based on the installation path, controlling the base assembly of the installation device to install the battery pack on the battery pack frame includes:

[0095] Step S205 : Based on the installation path, control the base assembly to drive the battery pack to move to a first target position.

[0096] Step S206 , in response to the base assembly being located at the first target position, controlling the lifting subassembly of the base assembly to drive the translation subassembly of the base assembly and the battery pack to move to the second target position.

[0097] Step S207 , in response to the translation subassembly being located at the second target position, controlling the translation subassembly to install the battery pack onto the battery pack frame.

[0098] In step S205, based on the calculated installation path, the controller 31 first controls the universal wheels 101 of the base assembly 10 to move the base body 100, the lifting subassembly 11, the translation subassembly 12, and the battery pack 50, thereby moving the battery pack 50 along the X and Y axes to a first target position horizontally aligned with the battery pack frame 60. This process may require multiple fine-tuning to ensure accurate alignment of the battery pack 50 with the battery pack frame 60 within the plane.

[0099] In step S206, once the base body 100 reaches the first target position, the controller 31 controls the lifting subassembly 11, driving the translation subassembly 12 and the battery pack 50 to move vertically to the second target position. The second target position is the height at which the locking pin 51 can accurately enter the lock body 61 and achieve locking. The controller 31 may monitor the lifting process in real time using signals from the laser radar 16 and receiver 17 to ensure accurate vertical alignment of the battery pack 50.

[0100] In step S207, once the battery pack 50 reaches the second target position through vertical movement of the lifting subassembly 11, the controller 31 controls the translation subassembly 12 to perform the final locking operation. This may involve slightly advancing the translation subassembly 12 along the X-axis to ensure that the locking mechanism between the locking pin 51 and the locking body 61 is fully engaged, thereby securely mounting the battery pack 50 on the battery pack frame 60. During this process, the drive motor 122 applies appropriate force according to the instructions of the controller 31 to ensure a smooth locking operation.

[0101] Through refined control of the aforementioned steps, the embodiments of the present invention achieve automated and intelligent installation of vehicle-mounted batteries. This not only significantly improves the accuracy and efficiency of battery pack 50 installation, but also significantly reduces operator workload and the risk of installation errors. This automated installation process, based on positional information and precise control, is a significant innovation in new energy vehicle assembly technology and provides a solid technical foundation for achieving higher levels of battery assembly automation.

[0102] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects:

[0103] 1) The base body 100 is equipped with universal wheels 101 with a drive motor and an angle sensor, which enables the base body 100 to move autonomously and precisely. Through real-time monitoring and control of the drive motor and the angle sensor by the controller 31, the power battery pack can be flexibly translated within a limited space, significantly reducing operational difficulty and improving assembly efficiency. The connecting platform 121 can precisely reciprocate in the length and width directions of the base body 100, that is, the position of the battery pack 50 can be freely adjusted on the X-axis and Y-axis, enabling rapid and accurate positioning of the battery pack, whether in a straight-line arrangement on the assembly line or in a complex layout that requires crossing obstacles.

[0104] 2) By using the integrated camera 21 to collect physical data and perform 3D coordinate modeling, combined with laser alignment technology, the controller 31 can automatically and accurately locate the relative position between the lock pin 51 and the lock body 61. Even with multiple alignment points, the system can quickly identify them, ensuring precise alignment of each point, significantly improving assembly accuracy and reliability.

[0105] 3) The controller 31 integrates data from the target component 41, the detection component 42, and the capacitive force sensor 43 to monitor the contact status between the lock pin 51 and the lock body 61 in real time. It then precisely controls the lift motor to ensure that the lock pin 51 stops moving the moment it contacts the lock body 61. This micron-level control accuracy effectively prevents excessive contact or collision, ensuring safety during the assembly process.

[0106] 4) Drive motor 122 in translation subassembly 12, under the precise control of controller 31, can provide up to 8000N of force, pushing connection platform 121 along slide rail 123, thereby pushing locking pin 51 on battery pack 50 into lock body 61, locking and securing it. This design overcomes the force application obstacles caused by the weight and volume of the battery pack, while also reducing the risk of damage to the device or battery pack.
