Description

Technical Field

[0001] This application belongs to the field of vehicle manufacturing and processing technology, and in particular relates to a vehicle production system. Background Technology

[0002] Current vehicle production lines are typically divided into interior lines, chassis lines, and exterior lines. Among these, most OEMs use sliding plate or chain conveyors for interior and exterior lines. Both sliding plate and chain conveyors require civil engineering structures (such as slide rails) to build the foundation, making them inconvenient to modify or expand, resulting in long downtime periods, large investments, poor adaptability to different vehicle models, and low efficiency. Utility Model Content

[0003] In view of the above problems, this application provides a vehicle production system that can alleviate the problem of low efficiency in the current vehicle production line for processing and modifying different vehicle models.

[0004] In a first aspect, embodiments of this application provide a vehicle production system for producing vehicles, the vehicle production system comprising:

[0005] The chassis includes at least a control system and a power system, and the chassis is capable of moving independently under the drive of the power system; the navigation trolley includes a vehicle body and a navigation control device mounted on the vehicle body, the navigation control device enables the navigation trolley to move along the processing path of the vehicle production system, and the navigation trolley is communicatively connected to the chassis to guide the chassis to move along the processing path by means of the power system.

[0006] In the technical solution of this embodiment, the chassis can move independently under the guidance of the navigation trolley and its own power system, saving the need for a sliding plate, chain, and corresponding civil engineering structure. The change of the vehicle's travel path can be achieved by changing the processing path in conjunction with the guidance of the navigation trolley, which improves the vehicle production system's adaptability to different vehicle models and reduces the cost of adapting the vehicle production system to different vehicle models.

[0007] In some embodiments, the chassis further includes a communication system, which is communicatively connected to the control system; the navigation control device is communicatively connected to the communication system.

[0008] The technical solution of this embodiment provides a specific structure for guiding the independent movement of the chassis of a navigation vehicle. A communication system is set on the chassis, which is connected to the control system, and the navigation control device is connected to the communication system. This allows the navigation control device to be indirectly connected to the control system through the communication system, so that the chassis can be controlled to move independently by the control system.

[0009] In some embodiments, the vehicle body is disposed adjacent to the chassis, and the vehicle body and the chassis are disposed at a distance.

[0010] In the technical solution of this embodiment, a vehicle body is set at a distance from the chassis, so that no additional navigation device needs to be mounted on the chassis, thereby reducing the space occupied by the navigation device on the chassis and also reducing the negative impact that the navigation device may have on the chassis assembly and processing.

[0011] In some embodiments, the navigation vehicle is positioned under the chassis.

[0012] In this embodiment, the navigation vehicle is positioned below the chassis, which allows the navigation control device of the navigation vehicle to communicate better with the communication system of the chassis and reduces potential external interference. At the same time, the chassis can also provide some protection for the navigation vehicle.

[0013] In some embodiments, the navigation vehicle further includes an information acquisition device mounted on the vehicle body. The information acquisition device collects location information for navigation of the navigation vehicle and is communicatively connected to the navigation control device.

[0014] In the technical solution of this embodiment, an information acquisition device is set up to collect environmental information around the navigation vehicle, so that the navigation control device can determine whether the chassis can move, whether there are intruders on the processing path, etc., based on the collected environmental information, thereby facilitating the navigation control device to control the walking state of the chassis.

[0015] In some embodiments, there are multiple information collection devices, which are respectively located on different sides of the vehicle body.

[0016] In this embodiment, multiple information collection devices are provided, and these devices are located on different sides of the vehicle body, so that each device can collect environmental information around the vehicle body more effectively and comprehensively.

[0017] In some embodiments, the vehicle body includes two first side surfaces spaced apart along its length, each first side surface having at least one information acquisition device; and / or the vehicle body also includes two second side surfaces spaced along its width, each second side surface having at least two information acquisition devices, and the at least two information acquisition devices on the same second side surface being spaced apart along the length of the vehicle body.

[0018] The technical solution of this embodiment provides some arrangement methods for information collection devices, so that the information collection devices can more comprehensively cover the space around the vehicle body and better collect environmental information around the vehicle body.

[0019] In some embodiments, the information collection device is located below the chassis; or at least a portion of the information collection device is located outside the chassis.

[0020] The technical solution of this embodiment provides the position of some information acquisition devices relative to the chassis to reduce the interference of the chassis on the information acquisition devices' collection of environmental information, thereby enabling the information acquisition devices to better collect environmental information around the chassis.

[0021] In some embodiments, the navigation vehicle further includes a synchronization device located on the side of the vehicle body facing the chassis, and the synchronization device is communicatively connected to the navigation control device.

[0022] In the technical solution of this embodiment, a synchronization device is set up to identify the position information of the chassis, so that the navigation control device can control the movement, stopping and other states of the navigation vehicle, thereby enabling the navigation vehicle to move synchronously or approximately synchronously with the chassis.

[0023] In some embodiments, the navigation vehicle further includes a navigation device located on the side of the vehicle body away from the chassis, and the navigation device is communicatively connected to the navigation control device.

[0024] In the technical solution of this embodiment, a navigation device is provided to confirm the travel path of the navigation trolley in conjunction with the processing path; at the same time, the navigation device is communicatively connected with the navigation control device so that the navigation control device can better control the chassis to travel along the processing path through the communication system and the control system.

[0025] In some embodiments, the chassis includes a chassis frame on which at least one of an electric drive system, a suspension system, a steering system, a braking system, a chassis electrical control system, and an energy storage system is provided.

[0026] In the technical solution of this embodiment, the chassis is designed to have one or more functions such as walking, shock absorption, steering, and start-stop, while also making the chassis a pre-assembled structure.

[0027] In some embodiments, the chassis is a skateboard chassis.

[0028] In this embodiment, the chassis is a skateboard chassis, which enables the chassis to move autonomously and independently, thus facilitating the chassis to move autonomously to various workstations.

[0029] In some embodiments, the vehicle production system further includes at least two workstations, including an entry workstation and at least one assembly workstation, wherein the navigation vehicle moves to a position below the chassis at the entry workstation; the entry workstation and at least one assembly workstation are arranged sequentially along the processing path.

[0030] In the technical solution of this embodiment, an entry station is set up so that the navigation trolley can move under the chassis, thereby enabling the navigation trolley to move synchronously with the chassis during subsequent processing. This facilitates the navigation trolley to collect environmental information around the chassis and to control the movement status of the chassis.

[0031] In some embodiments, the workstation further includes an exit station from which the navigation vehicle leaves the underside of the chassis; the exit station is located downstream of at least one assembly station.

[0032] In the technical solution of this embodiment, an exit station is set up, and the navigation vehicle can leave the chassis from under the exit station, thereby enabling the navigation vehicle to be reused.

[0033] In some embodiments, the vehicle production system also includes a return path, one end of which extends to the entry station and the other end of which extends to the exit station.

[0034] In the technical solution of this embodiment, a return path is set so that the navigation vehicle can return from the exit station to the entry station along the return path, thereby facilitating the reuse of the navigation vehicle.

[0035] In some embodiments, the assembly station includes a combination assembly station, which is equipped with combination assembly equipment for assembling the chassis and the upper body; the combination assembly station is located downstream of the entry station.

[0036] In the technical solution of this embodiment, a combined assembly station is set up and located downstream of the entry station, so that the chassis can move from the entry station to the combined assembly station. This reduces the civil engineering structure between the entry station and the combined assembly station, thereby further improving the adaptability of the entire vehicle processing system to different vehicle models and reducing the adaptation cost of the vehicle processing system to different vehicle models.

[0037] In some embodiments, the assembly station further includes an external assembly station, which is located downstream of the final assembly station.

[0038] In the technical solution of this embodiment, the assembly station includes an external assembly station, and the external assembly station is located downstream of the assembly station so that workers can perform assembly processing of structures such as seat belts, windows, and wiring harnesses.

[0039] In some embodiments, the assembly station further includes an interior assembly station, which is located downstream of the exterior assembly station.

[0040] In the technical solution of this embodiment, the assembly station includes an interior assembly station, so that workers can perform interior assembly processing on the vehicle.

[0041] The above description is only an overview of the technical solution of this application.

[0060] The embodiments of the technical solution of this application will now be described in detail with reference to the accompanying drawings. These embodiments are only used to more clearly illustrate the technical solution of this application and are therefore merely examples, and should not be used to limit the scope of protection of this application.

[0061] 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 application pertains; the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the application; the terms “comprising” and “having”, and any variations thereof, in the specification, claims, and foregoing description of the drawings are intended to cover non-exclusive inclusion.

In the description of the embodiments of this application, "multiple" means two or more, unless otherwise explicitly defined.

[0063] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0064] In the description of the embodiments in this application, the term "and / or" is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone. Additionally, the character " / " in this document generally indicates that the preceding and following related objects have an "or" relationship.

[0065] In the description of the embodiments of this application, the term "multiple" refers to two or more (including two), similarly, "multiple sets" refers to two or more (including two sets), and "multiple pieces" refers to two or more (including two pieces).

[0066] In the description of the embodiments of this application, the technical terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," and "circumferential" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings.

Therefore, they should not be construed as limitations on the embodiments of this application.

[0067] In the description of the embodiments of this application, unless otherwise expressly specified and limited, technical terms such as "installation," "connection," "joining," and "fixing" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. For those skilled in the art, the specific meaning of the above terms in the embodiments of this application can be understood according to the specific circumstances.

[0068] In current vehicle production lines, the movement of chassis and vehicles between workstations is typically achieved via sliding plates or chain conveyors. For sliding plates or chain conveyors, tracks must first be installed on the ground, or other structures such as guide rails must be installed above the work area; all of these structures require civil engineering construction.

[0069] The production and processing procedures required for different vehicle models will vary, which requires changing the direction of movement of the chassis and vehicle between various workstations, as well as the start and stop positions. Currently, the sliding plate and chain plate structures take a long time to modify after construction, have high costs, and long downtime periods. They also have poor adaptability to different vehicle models and low efficiency.

[0070] Based on the above considerations, in order to alleviate the problem of low efficiency in the current vehicle production line for processing and modifying different models, this application provides a vehicle production system, which includes a navigation trolley and a navigation control device on the vehicle body, so that the navigation control device can guide the chassis's walking, braking, steering and other actions.

[0071] In such a vehicle production system, the navigation trolley controls the chassis's walking, braking, and steering states through a navigation control device, enabling the chassis to move along the processing path with the navigation trolley and to move independently using its own power system without relying on skateboards, chains, grippers, and corresponding civil engineering structures. This improves the vehicle production system's adaptability to different vehicle models and reduces the cost of adapting the vehicle production system to different vehicle models.

[0072] The vehicle production system disclosed in this application can be used to produce different types and models of vehicles. The vehicles can be large cars, small cars, special vehicles, etc. For example, according to the vehicle type, the vehicle can be a sedan, an off-road vehicle, a multi-purpose vehicle (MPV), or other types of vehicles.

[0073] To illustrate the technical solution of this application, the following description is provided in conjunction with specific accompanying drawings and embodiments.

[0074] refer to Figures 1 to 5 This application provides a vehicle production system 1000 for producing vehicles 2000. The vehicle production system 1000 includes a chassis 500 and a navigation vehicle 100. The chassis 500 includes at least a control system and a power system, and is capable of independent movement under the drive of the power system. The navigation vehicle 100 includes a body 110 and a navigation control device 120 mounted on the body 110. The navigation control device 120 enables the navigation vehicle 100 to travel along a processing path 300 of the vehicle production system 1000. The navigation vehicle 100 is communicatively connected to the chassis 500 to guide the chassis 500 to move along the processing path 300 using the power system.

[0075] In the diagram, the X-axis represents the length of the navigation trolley 100, the length of the chassis 500, and the direction in which the chassis 500 moves forward or backward along the machining path 300; the Y-axis represents the width of the navigation trolley 100 and the width of the chassis 500; and the Z-axis represents the height of the navigation trolley 100 and the height of the chassis 500.

[0076] Chassis 500 refers to the frame structure at the bottom of vehicle 2000 and its associated mechanical components. Chassis 500 may include a chassis frame, powertrain, control system, or other structures. The powertrain refers to the system on chassis 500 that provides power to vehicle 2000, and may include structures such as an engine, electric motor, fuel tank, and battery pack. The control system refers to the system on chassis 500 that controls the operation of the powertrain, braking, steering, and electrical systems, and may include electronic control units, electronic stability control systems, brake force distribution systems, electric power steering systems, and four-wheel drive control systems.

[0077] The control system is connected to the power system, enabling it to control the start and stop of the power system; at the same time, the control system can also control the steering and braking of the chassis 500.

[0078] The processing path 300 refers to the arrangement path of each workstation 200 in the vehicle production system 1000, and is also the path on which the chassis 500 or vehicle 2000 moves and is processed. The processing path 300 can be a set virtual path and preset in the navigation car 100. The processing path 300 can also be a structure marked on the working surface (such as the ground) on which the vehicle 2000 travels, such as line images, magnetic strip structures, etc. The processing path 300 can vary depending on different vehicle models. In this case, only the processing path 300 needs to be changed for different vehicle models, without the need for structural disassembly, modification, installation, etc.

[0079] The navigation trolley 100 refers to the trolley in the vehicle production system 1000 that can move along the processing path 300. The navigation trolley 100 can also guide the chassis 500 to move along the processing path 300. The navigation trolley 100 can be remotely controlled by a person or can move automatically through various devices and preset programs installed on it.

[0080] The vehicle body 110 refers to the structure in the navigation vehicle 100 that provides a mounting base for other structures. The navigation vehicle 100's walking system, navigation control device 120, or other systems and electronic devices can all be mounted on the vehicle body 110. The vehicle body 110 can be a plate structure, a frame structure, a box structure, or other shaped structures. The shape of the vehicle body 110 can be prismatic, cylindrical, or other shapes. The material of the vehicle body 110 can include metal, plastic, or other materials.

[0081] The navigation control device 120 refers to the device in the navigation vehicle 100 used to send signals to the control system of the chassis 500 to control the state of the chassis 500. The navigation control device 120 may include a computer, a programmable logic controller (PLC), a distributed control system (DCS), or other equipment.

[0082] The navigation control device 120 may have a preset movement path that matches the processing path 300, so that the navigation control device 120 can control the navigation trolley 100 to move along the preset movement path.

[0083] The navigation control device 120 is mounted on the vehicle body 110. The navigation control device 120 can be mounted on the vehicle body 110 by welding, screwing, snapping or other means. Since the vehicle body 110 is spaced apart from and independent of the chassis 500, the navigation control device 120 is also spaced apart from and independent of the chassis 500. The navigation control device 120 does not occupy space on the chassis 500.

[0084] The navigation trolley 100 is communicatively connected to the chassis 500, enabling the navigation trolley 100 to guide the chassis 500 to move along the machining path 300 using its own power system. This allows the chassis 500 to move independently along the machining path 300 under the guidance of the navigation trolley 100, relying on its own power system. The communicative connection between the navigation trolley 100 and the chassis 500 allows the navigation control device 120 to communicate directly or indirectly with the control system of the chassis 500. It also allows the control system of the chassis 500 to communicate with other structures on the navigation trolley 100 to identify the position of the navigation trolley 100, thereby controlling the chassis 500 to move independently with the navigation trolley 100 based on the position.

[0085] For example, the navigation vehicle 100 can communicate with the control system of the chassis 500 through its navigation control device 120, so that the navigation control device 120 can indirectly control the movement of the chassis 500 through the control system, thereby achieving the effect of guiding the chassis 500 to move through the navigation vehicle 100; for example, the control system can also be made to identify the position of the navigation vehicle 100, so that the control system can control the power system to drive the chassis 500 to follow the navigation vehicle 100, thereby achieving the effect of guiding the chassis 500 to move through the navigation vehicle 100; it is understood that the navigation vehicle 100 can also guide the chassis 500 to move through other means, not limited to the two mentioned above.

[0086] During the process of the navigation vehicle 100 guiding and controlling the movement of the chassis 500, the navigation vehicle 100 can be located below the chassis 500, in front of or behind the chassis 500 along its length, or on one side of the chassis 500 along its width.

[0087] During the processing of chassis 500 in vehicle production system 1000, navigation trolley 100 can move to one side of chassis 500. Then, navigation trolley 100 can guide and control chassis 500 to move sequentially to each workstation 200 along processing path 300 and stay in each workstation 200. When chassis 500 stays in the corresponding workstation 200, the processing equipment and personnel corresponding to the corresponding workstation 200 can process chassis 500.

[0088] Understandably, during the process of the navigation vehicle 100 guiding and controlling the movement of the chassis 500, the upper body 600 can be assembled with the chassis 500. At this time, the navigation vehicle 100 is actually guiding and controlling the entire vehicle 2000.

[0089] During the processing of chassis 500 by vehicle production system 1000, chassis 500 can move to each workstation 200 by its own power system without relying on structures such as sliding plates, chain conveyors, and grippers, which greatly simplifies vehicle production system 1000. When the processing steps of chassis 500 need to be adjusted, only the preset movement path and corresponding processing path 300 in the navigation trolley 100 need to be adjusted, without the need for civil engineering modifications, which improves the adaptability of vehicle production system 1000 to different vehicle models, different processing steps, and different processing technologies, and reduces the cost of processing different vehicle models, adjusting different processing steps, and changing different processing technologies.

[0090] In this embodiment, the chassis 500 can move independently under the guidance of the navigation trolley 100 using its own power system, saving the need for a skateboard, chain, and corresponding civil engineering structures. The change of the vehicle 2000's travel path can be achieved by changing the processing path 300 in conjunction with the guidance of the navigation trolley 100, which improves the adaptability of the vehicle production system 1000 to different vehicle models and reduces the cost of adapting the vehicle production system 1000 to different vehicle models.

[0091] In some embodiments, the chassis 500 further includes a communication system, which is communicatively connected to the control system; the navigation control device 120 is communicatively connected to the communication system.

[0092] The communication system refers to the structure in the chassis 500 used to receive and send signals. The communication system is connected to the control system. The communication system can be connected to the control system wirelessly or via cable. The communication system can send control signals to the control system. The control system can control the power system and the control system itself to make corresponding actions based on the received control signals to drive the chassis 500 to move, stop, turn, etc.

[0093] The navigation control device 120 is connected to the communication system. The navigation control device 120 can be connected to the communication system wirelessly or in other ways. The navigation control device 120 can send navigation signals to the communication system, and the communication system can receive the navigation signals and generate control signals based on the navigation signals. That is, the navigation control device 120 can be indirectly connected to the control system through the communication system to control the movement state of the chassis 500 through the control system.

[0094] This embodiment provides a specific structure for the navigation vehicle 100 to guide the chassis 500 to move independently. A communication system is set on the chassis 500, which is connected to the control system. The navigation control device 120 is also connected to the communication system, so that the navigation control device 120 can be indirectly connected to the control system through the communication system, so that the chassis 500 can be controlled to move independently by the control system.

[0095] refer to Figure 2 , Figure 3 In some embodiments, the vehicle body 110 is disposed adjacent to the chassis 500, and the vehicle body 110 and the chassis 500 are disposed at a distance.

[0096] The vehicle body 110 is spaced apart from the chassis 500, meaning that the vehicle body 110 is set independently of the chassis 500 and is not directly connected to the chassis 500. This reduces the space occupied by the navigation vehicle 100 on the chassis 500 and reduces the negative impact that the navigation vehicle 100 may have on the subsequent processing of the chassis 500.

[0097] Understandably, the fact that the vehicle body 110 and the chassis 500 are not directly connected means that there is no physical connection structure between the vehicle body 110 and the chassis 500, and the navigation car 100 guides the chassis 500 to move without occupying space on the chassis 500.

[0098] The vehicle body 110 is positioned adjacent to the chassis 500 so that the navigation vehicle 100 can better guide the movement of the chassis 500 and reduce the risk of other objects being inserted between the vehicle body 110 and the chassis 500. This allows the navigation vehicle 100 to guide the chassis 500 to move along the processing path 300 more stably.

[0099] In this embodiment, a vehicle body 110 is provided at a distance from the chassis 500, so that no additional navigation device needs to be mounted on the chassis 500, thereby reducing the space occupied by the navigation device on the chassis 500 and also reducing the negative impact that the navigation device may have on the assembly and processing of the chassis 500.

[0100] refer to Figure 2 , Figure 3 In some embodiments, the navigation vehicle 100 is positioned below the chassis 500.

[0101] The navigation trolley 100 is located below the chassis 500. During the movement of the chassis 500, the navigation trolley 100 remains below it, and the chassis 500 moves synchronously with it, ensuring the navigation trolley 100 remains always below the chassis 500. At this time, the positions of the navigation trolley 100 and the chassis 500 overlap relative to the machining path 300, and the position of the navigation trolley 100 corresponds to that of the chassis 500. This allows for better determination of the chassis 500's position and facilitates the navigation trolley 100's guidance of the chassis 500 along the machining path 300. Simultaneously, this arrangement minimizes the distance between the vehicle body 110 and the chassis 500, thereby improving the stability of the communication connection between the navigation control device 120 and the chassis 500's communication system.

[0102] The navigation trolley 100 can always be located below the chassis 500 during the movement and processing of the chassis 500. At this time, the chassis 500 can also play a certain role in protecting the navigation trolley 100 and reduce the interference of the external environment on the navigation trolley 100, thereby improving the stability of the movement of the navigation trolley 100 and improving the stability of the communication connection between the navigation control device 120 and the communication system of the chassis 500.

[0103] In this embodiment, the navigation vehicle 100 is located below the chassis 500 so that the navigation control device 120 of the navigation vehicle 100 can better communicate with the communication system of the chassis 500 and reduce possible external interference; at the same time, the chassis 500 can also provide a certain degree of protection for the navigation vehicle 100.

[0104] refer to Figures 2 to 6 , Figure 8 In some embodiments, the navigation vehicle 100 also includes an information acquisition device 130 disposed on the vehicle body 110. The information acquisition device 130 collects location information for navigation of the navigation vehicle 100. The information acquisition device 130 is communicatively connected to the navigation control device 120.

[0105] Information acquisition device 130 refers to the structure in the navigation trolley 100 used to collect the position information of vehicle 2000. The position information of vehicle 2000 is the position of vehicle 2000 on the processing path 300 and the position of vehicle 2000 relative to each workstation 200. Information acquisition device 130 may include one or more cameras, radars or other information acquisition devices. The number of information acquisition devices 130 can be one, two or more. Information acquisition device 130 is installed on vehicle body 110 and can be connected to vehicle body 110 by welding, screwing, bonding or other means.

[0106] The information acquisition device 130 can acquire the relative position of the chassis 500 with each workstation 200 or its surrounding environment, and generate a position signal. The position signal refers to the signal generated by the information acquisition device 130 in real time monitoring the position of the vehicle 2000. The position signal can be an electrical signal, an optical signal or other form of signal. The position signal reflects the position of the vehicle 2000 on the processing path 300, so that the subsequent navigation control device 120 or other devices can determine the position of the vehicle 2000 relative to each workstation 200.

[0107] The information acquisition device 130 is communicatively connected to the navigation control device 120. The information acquisition device 130 can send the position signals it acquires to the navigation control device 120. The navigation control device 120 can control the walking state of the vehicle 2000 through the communication system of the chassis 500 based on the received position signals, and enable the vehicle 2000 to walk, brake, steer, or perform other actions, so that the vehicle 2000 can sequentially pass through each workstation 200 along the processing path 300 and stop at each workstation 200.

[0108] In addition to collecting the location information of the vehicle 2000 and forming a location signal, the information collection device 130 can also collect information on intrusions on the processing path 300. Intrusions refer to substances that overlap with the processing path 300, and intrusions can be people, robotic arms, or other substances.

[0109] The information acquisition device 130 can generate a safety signal when an intrusion is present on the processing path 300. The safety signal is a signal generated by the information acquisition device 130 after it detects the presence of an intrusion on the processing path 300. The safety signal can be an electrical signal, an optical signal, or a signal of other forms. The generation of a safety signal by the information acquisition device 130 means that there is an intrusion on the processing path 300. This intrusion will hinder the movement of the vehicle 2000 along the processing path 300. A collision between the vehicle 2000 and the intrusion may cause damage to both the vehicle 2000 and the intrusion, thereby causing a safety problem.

[0110] Because the information acquisition device 130 is communicatively connected to the navigation control device 120, the information acquisition device 130 can also send the generated safety signal to the navigation control device 120. The navigation control device 120 can generate a control signal based on the received position signal and safety signal to control the start and stop of the vehicle 2000. For example, the navigation control device 120 can determine the distance between the vehicle 2000 and the intruder based on the position signal and safety signal, and can issue a control signal to control the vehicle 2000 to stop before the intruder through the signal transceiver device, thereby reducing the risk of the vehicle 2000 colliding with the intruder.

[0111] Understandably, after vehicle 2000 stops moving, the staff can remove the intruder from processing path 300. After the intruder leaves processing path 300, information collection device 130 no longer generates a safety signal, and navigation control device 120 can control vehicle 2000 to start and continue moving accordingly.

[0112] In this embodiment, an information acquisition device 130 is provided to collect environmental information around the navigation vehicle 100. This allows the navigation control device 120 to determine whether the chassis 500 can move or whether there are intruders on the processing path 300 based on the collected environmental information. This facilitates the navigation control device 120 in controlling the movement of the chassis 500 and improves the safety performance of the vehicle 2000.

[0113] refer to Figures 2 to 5 , Figure 8 In some embodiments, there are multiple information collection devices 130, which are respectively located on different sides of the vehicle body 110.

[0114] There are multiple information collection devices 130. The number of information collection devices 130 can be two, three or more. The multiple information collection devices 130 are respectively installed on different sides of the vehicle body 110. Depending on the number of information collection devices 130, the information collection devices 130 can be installed on both sides, three sides, or all sides of the vehicle body 110. Only one information collection device 130 can be installed on the same side of the vehicle body 110, or two or more information collection devices 130 can be installed.

[0115] Since the information acquisition device 130 is used to collect both the position information of the chassis 500 and the status of intrusions around the chassis 500, it should be able to collect environmental information from all directions around the chassis 500 to generate more accurate position and safety signals. Accordingly, the information acquisition devices 130 are positioned on different sides of the vehicle body 110 so that each device can collect position and intrusion information from different sides of the chassis 500, thereby enabling the navigation control device 120 to more accurately determine the position of the chassis 500 and the status of intrusions based on the position and safety signals generated by each device 130.

[0116] In this embodiment, there are multiple information collection devices 130, and the multiple information collection devices 130 are respectively located on different sides of the vehicle body 110, so that each information collection device 130 can collect environmental information around the vehicle body 110 better and more comprehensively.

[0117] refer to Figures 4 to 7In some embodiments, the vehicle body 110 includes two first side surfaces 111 arranged at intervals along its length, and at least one information acquisition device 130 is provided on the first side surface 111; and / or the vehicle body 110 also includes two second side surfaces 112 arranged along its width, and at least two information acquisition devices 130 are provided on the second side surface 112, and the at least two information acquisition devices 130 on the same second side surface 112 are arranged at intervals along the length of the vehicle body 110.

[0118] The first side surface 111 refers to the surface located around the vehicle body 110. There are two first side surfaces 111, which are arranged along the length direction X of the vehicle body 110. Depending on the shape and structure of the vehicle body 110, the first side surface 111 can be a circular surface, a square surface, or a surface of other shapes. The first side surface 111 can be a plane or a curved surface.

[0119] At least one information acquisition device 130 is provided on a first side 111. That is, only one information acquisition device 130 can be provided on the first side 111, or two or more information acquisition devices 130 can be provided, so that the information acquisition device 130 can more comprehensively collect the location information and intruder information in the environment corresponding to the first side 111.

[0120] The second side surface 112 refers to the surface located around the perimeter of the vehicle body 110. There are two second side surfaces 112 arranged along the width direction Y of the vehicle body 110. Depending on the shape and structure of the vehicle body 110, the second side surface 112 can be a circular surface, a square surface, or a surface of other shapes. The second side surface 112 can be a plane or a curved surface. For example, when the vehicle body 110 has a cuboid structure, the sides of the vehicle body 110 only include two first side surfaces 111 and two second side surfaces 112.

[0121] At least two information acquisition devices 130 are provided on one of the second side sides 112, that is, two information acquisition devices 130 or three or more information acquisition devices 130 can be provided on the second side side 112; at least two information acquisition devices 130 are arranged at intervals along the length direction X of the vehicle body 110 on the corresponding second side side 112, so that the information acquisition devices 130 can more comprehensively collect the location information and intrusion information in the environment corresponding to the second side side 112.

[0122] Since the environment corresponding to the second side 112 is the same as the environment corresponding to the side of the vehicle 2000, while the environment corresponding to the first side 111 is the same as the environment corresponding to the front or rear of the vehicle 2000, the information collection device 130 on the second side 112 needs to collect more information than the information collection device 130 on the first side 111. Therefore, at least two information collection devices 130 are provided on the second side 112 to enable each information collection device 130 to more comprehensively collect the location information and intrusion information of the corresponding environment.

[0123] For example, an information collection device 130 is provided on each of the two first sides 111 of the vehicle body 110; two information collection devices 130 are provided on each of the two second sides 112 of the vehicle body 110, and the two information collection devices 130 on the same second side 112 are arranged at intervals along the length direction X of the vehicle body 110.

[0124] For example, two information acquisition devices 130 are respectively provided on the two first sides 111 of the vehicle body 110, and the two information acquisition devices 130 on the same first side 111 are arranged at intervals along the width direction Y of the vehicle body 110; two information acquisition devices 130 are respectively provided on the two second sides 112 of the vehicle body 110, and the two information acquisition devices 130 on the same second side 112 are arranged at intervals along the length direction X of the vehicle body 110.

[0125] This embodiment provides some arrangement of information collection devices 130 so that the information collection devices 130 can more comprehensively cover the space around the vehicle body 110 and better collect environmental information around the vehicle body 110.

[0126] refer to Figure 2 , Figure 3 , Figure 6 In some embodiments, the information acquisition device 130 is located below the chassis 500; or at least a portion of the information acquisition device 130 is located outside the chassis 500.

[0127] Since the information acquisition device 130 is used to collect environmental information around the chassis 500 and generate position and safety signals, the positions of the information acquisition device 130 and the chassis 500 should be close to or overlap. Accordingly, the information acquisition device 130 is positioned below the chassis 500. At this time, the position of the information acquisition device 130 is close to or overlaps with the chassis 500, and the environmental information collected by each information acquisition device 130 is the environmental information around the chassis 500.

[0128] The information acquisition device 130 is positioned below the chassis 500, enabling it to collect environmental information around the chassis 500 and generate position and safety signals. At the same time, the chassis 500 can also provide some protection for the information acquisition device 130, reducing the risk of collisions with and damage to the information acquisition device 130 by equipment or debris in the external environment.

[0129] Understandably, the information acquisition device 130 should be able to extend beyond the chassis 500 so that it can collect environmental information around the chassis 500.

[0130] At least a portion of the information acquisition device 130 extends beyond the chassis 500. Depending on the structure of the vehicle body 110, the information acquisition device 130 may be located only partially outside the chassis 500 or completely outside the chassis 500. The fact that the information acquisition device 130 is located outside the chassis 500 can reduce the negative impact that the chassis 500 may have on the acquisition range of the information acquisition device 130, thereby enabling the information acquisition device 130 to better acquire environmental information around the chassis 500 and to form more accurate position signals and safety signals.

[0131] This embodiment provides the position of some information acquisition devices 130 relative to the chassis 500 to reduce the interference of the chassis 500 on the information acquisition devices 130 in collecting environmental information, thereby enabling the information acquisition devices 130 to better collect environmental information around the chassis 500.

[0132] refer to Figures 4 to 6 , Figure 8 In some embodiments, the navigation vehicle 100 further includes a synchronization device 140, which is located on the side of the vehicle body 110 facing the chassis 500 and is communicatively connected to the navigation control device 120.

[0133] The synchronization device 140 refers to the device in the navigation vehicle 100 used to collect the relative position of the chassis 500 and the vehicle body 110. The synchronization device 140 may include a distance sensor, a vision sensor or other detection device to detect the distance between the vehicle body 110 and the chassis 500. The synchronization device 140 is communicatively connected to the navigation control device 120. The synchronization device 140 can be wirelessly connected to the navigation control device 120 or can be communicatively connected to the navigation control device 120 via a cable. The synchronization device 140 can collect the relative position of the chassis 500 and the vehicle body 110 and form a synchronization signal. This synchronization signal can be sent to the navigation control device 120. The navigation control device 120 can control the vehicle to move, accelerate, decelerate, brake or perform other actions through the synchronization signal so that the navigation vehicle 100 can move synchronously with the chassis 500.

[0134] As the chassis 500 moves, the navigation vehicle 100 needs to move synchronously to collect environmental information around the chassis 500. Therefore, a synchronization device 140 is set up so that the navigation control device 120 can control the movement state of the navigation vehicle 100 according to the relative position information of the chassis 500 and the vehicle body 110 collected in real time by the synchronization device 140.

[0135] The synchronization device 140 is mounted on the vehicle body 110. The synchronization device 140 can be connected to the vehicle body 110 by welding, bonding, screwing, snapping or other means. The synchronization device 140 is located on the side of the vehicle body 110 facing the chassis 500 so that the synchronization device 140 can obtain the relative position information between the chassis 500 and the vehicle body 110.

[0136] For example, when the synchronization device 140 is a distance sensor, the synchronization device 140 can collect the distance between the chassis 500 and the vehicle body 110 in real time and generate a synchronization signal to send to the navigation control device 120. When the distance between the vehicle body 110 and the chassis 500 is greater than a preset range, the navigation control device 120 can control the vehicle body 110 to accelerate or decelerate so that the navigation car 100 can move synchronously or approximately synchronously with the chassis 500.

[0137] In this embodiment, a synchronization device 140 is provided to identify the position information of the chassis 500 so that the navigation control device 120 can control the movement, stopping and other states of the navigation vehicle 100, thereby enabling the navigation vehicle 100 to move synchronously or approximately synchronously with the chassis 500.

[0138] refer to Figures 2 to 4 , Figure 8 In some embodiments, the navigation vehicle 100 further includes a navigation device 150, which is located on the side of the vehicle body 110 away from the chassis 500 and is communicatively connected to the navigation control device 120.

[0139] Navigation device 150 refers to the device in navigation trolley 100 used to guide the vehicle body 110 to move along the processing path 300. Navigation device 150 may include visual navigation device 150, laser navigation device 150 or other navigation devices 150.

[0140] For example, a metal line can be preset on the working surface (e.g., the ground) on which the vehicle 2000 travels and serves as the processing path 300, so that the navigation device 150 includes an electromagnetic navigation device 150. At this time, the electromagnetic navigation device 150 can identify the metal line, thereby facilitating the navigation control device 120 to control the navigation trolley 100 to travel along the processing path 300.

[0141] For example, the navigation device 150 may have a preset travel path that coincides with the processing path 300.

[0142] The navigation device 150 is communicatively connected to the navigation control device 120. The navigation control device 120 can receive signals sent by the navigation device 150 and control the direction of movement of the navigation trolley 100, thereby enabling the navigation trolley 100 to move along the processing path 300. Furthermore, the navigation control device 120 can also control the chassis 500 to move along the processing path 300 through the communication system and the control system.

[0143] The navigation device 150 is mounted on the vehicle body 110. The navigation device 150 can be connected to the vehicle body 110 by welding, bonding, snapping, screwing or other means. The navigation device 150 is located on the side of the vehicle body 110 away from the chassis 500, that is, on the side of the vehicle body 110 facing the ground. When the navigation device 150 includes an electromagnetic navigation device 150 for identifying metal wires, this arrangement facilitates the navigation device 150 in identifying metal wires on the working surface.

[0144] In this embodiment, a navigation device 150 is provided to confirm the travel path of the navigation trolley 100 in conjunction with the processing path 300. At the same time, the navigation device 150 is communicatively connected to the navigation control device 120 so that the navigation control device 120 can better control the chassis 500 to travel along the processing path 300 through the communication system and the control system.

[0145] In some embodiments, the chassis 500 includes a chassis frame on which at least one of an electric drive system, a suspension system, a steering system, a braking system, a chassis electrical control system, and an energy storage system is provided.

[0146] The chassis frame refers to the main supporting structure of the vehicle 2000. The chassis frame can be connected to the front and rear axles of the vehicle 2000. The chassis frame can be a frame structure and includes multiple longitudinal beams and cross beams. The chassis frame is mainly used to provide the mounting foundation and support for other structures of the vehicle 2000, and to bear various loads inside and outside the vehicle 2000.

[0147] An electric drive system refers to a system in chassis 500 that converts electrical energy into mechanical energy to drive chassis 500 to move, and thus drive vehicle 2000 to travel; an electric drive system may include a drive motor, inverter, gearbox and other structures.

[0148] The suspension system refers to the structure in the chassis 500 used to buffer the impact load on the chassis 500 due to uneven road surface. The suspension system can also buffer the vibration caused by this, reduce the vibration of the vehicle 2000 itself, and maintain the contact between the tires and the ground. The suspension system can also control the attitude of the vehicle 2000 to reduce the risk of excessive tilting or swaying of the vehicle 2000.

[0149] The steering system refers to the structure in the chassis 500 used to control the steering of the wheels and the driving direction of the vehicle 2000. The steering system can both change the driving mode of the vehicle 2000 and maintain the driving direction of the vehicle 2000.

[0150] The braking system refers to the structure in the chassis 500 used for deceleration. The braking system can decelerate or stop the vehicle 2000 during driving. The braking system can also maintain the speed of the vehicle 2000 when going downhill, thereby improving the handling, stability and safety of the vehicle 2000.

[0151] The transmission system refers to the structure in the chassis 500 used to transmit power. The transmission system can transmit power from the engine or electric motor to the wheels. The transmission system can include structures such as clutch, gearbox, drive shaft, reducer, differential, and half shaft.

[0152] The chassis electrical control system refers to the control structure in the chassis 500 used to control the electrical equipment on the chassis 500. The chassis electrical control system may include a power supply system, a control subsystem, and an execution subsystem. The power supply system may include devices such as batteries and generator regulators. The control subsystem may include devices such as electronic control units (ECUs) and chassis 500 control modules (BCMs). The execution subsystem may include devices such as electric motors and solenoid valves. The chassis electrical control system can control the braking system, steering system, suspension system, or other systems and devices of the chassis 500.

[0153] An energy storage system refers to a structure in the chassis 500 used to power the vehicle 2000. The energy storage system may include battery devices or other energy storage devices to provide electrical energy to the electric motor or engine of the vehicle 2000.

[0154] Depending on the vehicle model, one or more of the following systems can be installed on the chassis frame: electric drive system, suspension system, steering system, braking system, chassis electrical control system, and energy storage system.

[0155] In some embodiments, chassis 500 is a skateboard chassis 500.

[0156] The skateboard chassis 500 refers to an integrated electric vehicle chassis 500 platform, which integrates the battery, motor, electronic control system, suspension system, braking system, etc., all inside the chassis 500. When the chassis 500 is a skateboard chassis 500, the chassis 500 can perform actions such as walking, stopping, and turning. When the navigation control device 120 is connected to the communication system of the chassis 500 through a signal transceiver device, the navigation control device 120 can control the action state of the chassis 500, so that the chassis 500 can move autonomously to various workstations 200 without the aid of external equipment (such as cranes).

[0157] In this embodiment, the chassis 500 is a skateboard chassis 500, so that the chassis 500 has the ability to move autonomously and independently, thereby facilitating the chassis 500 to move autonomously to each workstation 200.

[0158] refer to Figure 7 In some embodiments, the vehicle production system 1000 further includes at least two workstations 200, each including an entry workstation 210 and at least one assembly workstation 220, wherein the navigation vehicle 100 moves to a position below the chassis 500 at the entry workstation 210; the entry workstation 210 and the at least one assembly workstation 220 are arranged sequentially along the processing path 300.

[0159] Workstation 200 refers to the space in the vehicle production system 1000 used for workers or processing equipment to process vehicles 2000. Workstation 200 can be a set spatial area or a spatial area enclosed by structural components. The number of workstations 200 is at least two. The vehicle production system 1000 may include only two workstations 200 or may include three or more workstations 200.

[0160] Assembly station 220 refers to station 200 used for assembling vehicle 2000. Assembly station 220 can provide space for the assembly of wiring harness, windshield, seat belt and other structures of vehicle 2000. Assembly station 220 can also provide space for the assembly of dashboard, roof, carpet and other structures of vehicle 2000. Assembly station 220 can be a set space area or a space area surrounded by structural components. The number of assembly stations 220 can be one, two or more. When there are two or more assembly stations 220, multiple assembly stations 220 can be set up sequentially along processing path 300.

[0161] Entering station 210 refers to the station 200 below the chassis 500 where the navigation trolley 100 moves. Entering station 210 can be a set spatial area or a spatial area enclosed by structural components. Entering station 210 provides space for the navigation trolley 100 and chassis 500 to move synchronously. When chassis 500 moves to entering station 210, navigation trolley 100 can be located below chassis 500. The navigation control device 120 of navigation trolley 100 can communicate with the communication system of chassis 500. After that, navigation trolley 100 can control chassis 500 to leave entering station 210 and move, turn, brake, etc. along processing path 300.

[0162] The navigation trolley 100 can be positioned in the entry station 210 in advance. After the chassis 500 moves to the entry station 210, the navigation trolley 100 can be positioned directly under the chassis 500. Alternatively, the navigation trolley 100 can move to the underside of the chassis 500 after the chassis 500 moves to the entry station 210.

[0163] Understandably, the chassis 500 that moves to workstation 210 is a chassis 500 that has already been processed in the previous machining process. This chassis 500 has an electric drive system, suspension system, steering system, braking system, energy storage system, etc. For example, this chassis 500 can be a skateboard chassis 500.

[0164] The entry station 210 and at least one assembly station 220 are arranged sequentially along the processing path 300. That is, the entry station 210 is in front of at least one assembly station 220, and the vehicle 2000 and the navigation trolley 100 pass through one or more assembly stations 220 in sequence after leaving the entry station 210.

[0165] Understandably, the vehicle production system 1000 may also include other stations 200 between the entry station 210 and the assembly station 220, and between each assembly station 220; the vehicle production system 1000 may also include other stations 200 before the entry station 210 and after the last assembly station 220.

[0166] In this embodiment, an entry station 210 is provided so that the navigation trolley 100 can move to the bottom of the chassis 500, thereby enabling the navigation trolley 100 to move synchronously with the chassis 500 during subsequent processing. This facilitates the navigation trolley 100 in collecting environmental information around the chassis 500 and in controlling the movement of the chassis 500.

[0167] refer to Figure 7 In some embodiments, station 200 further includes exit station 230, from which the navigation vehicle 100 leaves below the chassis 500; exit station 230 is located downstream of at least one assembly station 220.

[0168] Exit station 230 refers to the station 200 in the vehicle production system 1000 where the navigation trolley 100 leaves the vehicle 2000. Exit station 230 can be a set spatial area or a spatial area enclosed by structural components. After the vehicle 2000 and the navigation trolley 100 enter exit station 230, the navigation control device 120 of the navigation trolley 100 loses its communication connection with the communication system of the chassis 500. After that, the navigation trolley 100 and the vehicle 2000 can leave exit station 230 respectively.

[0169] Vehicle 2000 and navigation trolley 100 can leave exit station 230 from the same direction or from different directions; vehicle 2000 and navigation trolley 100 can leave exit station 230 simultaneously or leave exit station 230 one after the other.

[0170] Exit station 230 is located downstream of at least one assembly station 220. When there is only one assembly station 220, exit station 230 is located downstream of that assembly station 220. When there are multiple assembly stations 220, exit station 230 can be located downstream of the last assembly station 220 or any other assembly station 220.

[0171] The exit station 230 is located downstream of the assembly station 220. That is, after the chassis 500 has been processed and assembled at the assembly station 220, the navigation trolley 100 can be disconnected from the vehicle 2000 and no longer move synchronously. This facilitates subsequent processing procedures for the vehicle 2000, such as inspection and delivery.

[0172] After leaving the exit station 230, the navigation trolley 100 can be transported to or near the entry station 210 to wait for the next cooperation with other chassis 500.

[0173] In this embodiment, an exit station 230 is provided, and the navigation vehicle 100 can leave the underside of the chassis 500 at the exit station 230, thereby enabling the navigation vehicle 100 to be reused.

[0174] refer to Figure 7 In some embodiments, the vehicle production system 1000 also includes a return path 400, one end of which extends to the entry station 210 and the other end of which extends to the exit station 230.

[0175] The return path 400 refers to the movement path of the navigation trolley 100 in the vehicle production system 1000 outside the processing path 300. The return path 400 can be a set virtual path or a preset path in the navigation control device 120. The return path 400 can also be a structure marked on the working surface (such as the ground) on which the navigation trolley 100 travels, such as a line image, a magnetic strip structure, etc.

[0176] One end of the return path 400 extends to the entry station 210, and the other end extends to the exit station 230. After the navigation trolley 100 leaves the exit station 230, the navigation trolley 100 can move along the return path 400 and move to the entry station 210, which facilitates the navigation trolley 100 to cooperate with another chassis 500.

[0177] For example, the regression path 400 is independent of the processing path 300, that is, the regression path 400 and the processing path 300 do not intersect or overlap, so as to reduce the risk of mutual interference between the navigation vehicle 100 and the chassis 500 during the regression movement.

[0178] In this embodiment, a return path 400 is set so that the navigation vehicle 100 can return from the exit station 230 to the entry station 210 along the return path 400, thereby facilitating the reuse of the navigation vehicle 100.

[0179] refer to Figure 7 In some embodiments, the assembly station 220 includes a combination assembly station 221, which is equipped with a combination assembly device for assembling the chassis 500 and the upper body 600; the combination assembly station 221 is located downstream of the entry station 210.

[0180] Assembly station 221 refers to station 200 used to assemble the upper body 600 and chassis 500. Assembly station 221 can be a set space area or a space area enclosed by structural components. Assembly station 221 provides space for the upper body 600 to be installed on chassis 500. Welding, bolting and other processes between upper body 600 and chassis 500 can all be completed in assembly station 221.

[0181] The assembly equipment refers to the equipment set up in the assembly station 221 and used to assemble the chassis 500 and the upper body 600. The workers can use the assembly equipment to assemble the chassis 500 and the upper body 600 in the assembly station 221. The assembly equipment may include positioning equipment, lifting equipment, etc. Depending on the assembly method of the chassis 500 and the upper body 600, the assembly equipment may also include welding equipment, bolt pre-tightening equipment, etc., to assist the workers in assembling the chassis 500 and the upper body 600.

[0182] The assembly station 221 is located downstream of the entry station 210, meaning that the signal transceiver is installed first, followed by the assembly of the chassis 500 and the upper body 600. With the signal transceiver installed on the chassis 500, it is first installed on the chassis 500 in the entry station 210. Afterward, the signal transceiver can control the chassis 500 to autonomously move to the assembly station 200, facilitating the assembly of the upper body 600 onto the chassis 500. With this setup, no civil engineering structures such as clamps or chain plates are needed between the entry station 210 and the assembly station 221, further improving the adaptability of the vehicle production system 1000 and reducing the adaptation cost of the vehicle production system 1000 to different vehicle models 2000.

[0183] In this embodiment, the entry station 210 moves automatically to the assembly station 221, thereby reducing the civil engineering structure between the entry station 210 and the assembly station 221. This further improves the adaptability of the entire vehicle 2000 processing system to different models of vehicles 2000 and reduces the adaptation cost of the vehicle 2000 processing system to different models of vehicles 2000.

[0184] refer to Figure 7 In some embodiments, assembly station 220 further includes an external assembly station 222, which is located downstream of assembly station 221.

[0185] The external assembly station 222 refers to the station 200 used to install structures such as doors, windows, lights, lighting, and wiring harnesses onto the assembled vehicle 2000. The external assembly station 222 can be a designated spatial area or a spatial area enclosed by structural components. The external assembly station 222 provides space for the mechanical and electrical assembly of the vehicle 2000. Mechanical assembly may include the assembly of mechanical structures such as doors, windows, and lights, while electrical assembly may include the assembly of electrical structures such as lighting and wiring harnesses. The external assembly station 222 may consist of only one space, in which various mechanical and electrical structures are assembled. Alternatively, the external assembly station 222 may include multiple different subspaces, which are arranged along the processing path 300, with each different mechanical and electrical structure being assembled in its respective subspace.

[0186] The assembly process in the exterior assembly station 222 can be handled by workers alone, or assembly equipment can be set up to assist workers in interior assembly, or automatic assembly equipment can be set up to achieve exterior assembly.

[0187] The external assembly station 222 is located downstream of the assembly station 221. After the upper body 600 and chassis 500 are assembled, the assembled vehicle 2000 can move to the external assembly station 222 on its own for the assembly of mechanical and electrical structures. When the external assembly station 222 includes multiple different subspaces, the assembled vehicle 2000 can pass through each subspace sequentially along the processing path 300 for the assembly of different mechanical and electrical structures. During the external assembly process, different mechanical and electrical structures can be installed on the upper body 600 or chassis 500 as needed.

[0188] In this embodiment, the assembly station 220 includes an external assembly station 222, and the external assembly station 222 is located downstream of the assembly station 221 so that workers can perform assembly of structures such as seat belts, windows, and wiring harnesses.

[0189] refer to Figure 7 In some embodiments, assembly station 220 further includes interior assembly station 223, which is located downstream of exterior assembly station 222.

[0190] Interior assembly station 223 refers to station 200 in assembly station 220 used to assemble interior parts for vehicle 2000. Assembly station 220 can be a defined spatial area or a spatial area enclosed by structural components. The interior parts assembled at interior assembly station 223 may include dashboard, headliner, seats, carpets, interior trim, or other structures. Interior assembly station 223 may include only one space, in which different structures are assembled. Interior assembly station 223 may also include multiple different subspaces, in which case the multiple different subspaces are arranged along the processing path 300, and each different structure is assembled in a different subspace.

[0191] The interior assembly process in the interior assembly station 223 can be handled by workers alone, or assembly equipment can be set up to assist workers in the interior assembly process, or automatic assembly equipment can be set up to complete the interior assembly process by the assembly equipment alone.

[0192] The interior assembly station 223 is located downstream of the exterior assembly station 222. After the exterior assembly is completed, the vehicle 2000 can move to the interior assembly station 223 for interior assembly. When the interior assembly station 223 includes multiple different sub-spaces, the vehicle 2000 can pass through each sub-space sequentially along the processing path 300 for different structures to be assembled. During the interior assembly process, different structures can be installed on the upper body 600 or the chassis 500 as needed.

[0193] In this embodiment, the assembly station 220 includes an interior assembly station 223, so that workers can perform interior assembly on the vehicle 2000.

[0194] In some embodiments, the vehicle production system 1000 includes an entry station 210, an assembly station 221, an exterior assembly station 222, an interior assembly station 223, and an exit station 230 arranged sequentially along the processing path 300.

[0195] The vehicle production system 1000 also includes a navigation vehicle 100, which includes a body 110 and a navigation control device 120. The navigation control device 120 can communicate with the communication system of the chassis 500. The body 110 has two first side surfaces 111 arranged along its length direction X, and each first side surface 111 is equipped with an information acquisition device 130. The body 110 also has two second side surfaces 112 arranged along its width direction Y, and each second side surface 112 is equipped with two information acquisition devices 130. The two information acquisition devices 130 on the same second side surface 112 are arranged at intervals along the length direction X of the body 110. Each information acquisition device 130 is communicatively connected to the navigation control device 120.

[0196] The vehicle 2000 includes a chassis 500 and a body 600. The chassis 500 includes a communication system, a control system, and a power system. The communication system is connected to the control system, and the control system is connected to the power system.

[0197] After the chassis 500 moves into the workstation 210, the navigation control device 120 of the navigation trolley 100 can communicate with the communication system of the chassis 500 and control the movement, steering, braking and other actions of the chassis 500 through the communication system and the control system.

[0198] The navigation vehicle 100 also includes a synchronization device 140 and a navigation device 150 mounted on the vehicle body 110; wherein, the synchronization device 140 is located at the upper end of the vehicle body 110 and is communicatively connected to the navigation control device 120; the navigation device 150 is located at the lower end of the vehicle body 110 and is communicatively connected to the navigation control device 120.

[0199] The chassis 500 is processed in the previous process and sent to the entry station 210. After the chassis 500 is sent to the entry station 210, the navigation trolley 100 is located below the chassis 500, and the navigation control device 120 is connected to the communication system of the chassis 500.

[0200] The navigation trolley 100 controls the chassis 500 to move synchronously and move to the assembly station 221, where the upper body 600 is assembled with the chassis 500 to form the assembled vehicle 2000.

[0201] The navigation trolley 100 controls the assembled vehicle 2000 to autonomously move to the exterior assembly station 222 and the interior assembly station 223 in sequence, so as to facilitate the exterior and interior assembly of the assembled vehicle 2000.

[0202] The navigation trolley 100 controls the vehicle 2000, whose exterior and interior assembly is completed, to enter the exit station 230. The navigation trolley 100 leaves the exit station 230 and returns to the vicinity of the entry station 210 or to the entry station 210 via the return path 400. The vehicle 2000 can then leave the exit station 230, go offline, and enter the subsequent process.

[0203] During the autonomous movement of the vehicle 2000 controlled by the navigation trolley 100, each information acquisition device 130 can collect the position signal of the vehicle 2000 in real time and send it to the navigation control device 120. The navigation control device 120 can control the start and stop of the vehicle 2000 according to the received position signal. After the vehicle 2000 enters the required position of the corresponding workstation 200, the navigation control device 120 can control the vehicle 2000 to stop so that the vehicle 2000 can be processed.

[0204] During the autonomous movement of vehicle 2000, each information acquisition device 130 can generate a safety signal after an intruder enters the processing path 300 and send the safety signal to navigation control device 120. Navigation control device 120 can control the start and stop of vehicle 2000 based on the received safety signal. After an intruder enters the processing path 300, navigation control device 120 determines the distance between vehicle 2000 and the intruder through the safety signal and position signal, and controls vehicle 2000 to stop before collision with the intruder; after the intruder leaves the processing path 300, the safety signal changes or disappears, at which point navigation control device 120 controls vehicle 2000 to start.
