Description

Technical Field

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

[0002] In vehicle production, the upper body and chassis are typically manufactured separately and then assembled in the final assembly workshop to form the complete vehicle. Currently, the upper body structure is quite complex, involves numerous production steps, is cumbersome, and has low production efficiency. Summary of the Invention

[0003] In view of the above problems, this application provides a vehicle production method, a vehicle, and a vehicle production line, which can alleviate the current problem of low production efficiency of upper body.

[0004] In a first aspect, embodiments of this application propose a vehicle production method, comprising:

[0005] The chassis is constructed, which includes the chassis frame, and the pillar outer panels and sill structures are installed on the chassis frame; the upper body is constructed, which includes pillars and a roof structure, with the pillars connected to the roof structure; the upper body and chassis are then assembled.

[0006] In this embodiment, the pillar outer panel and sill structure are mounted on the chassis frame. Simultaneously, during the upper body manufacturing process, the pillar and roof structure are connected, eliminating the need for the pillar outer panel and sill structure in the upper body. This reduces the number of structures in the upper body and simplifies the manufacturing process. Regarding the chassis manufacturing process, due to the complexity of the chassis structure, it is difficult to eliminate certain processes. Therefore, by mounting the pillar outer panel and sill structure on the chassis frame and processing them using the chassis's manufacturing equipment, the existing processes, equipment, and workshops can be utilized without adding additional steps. In other words, this embodiment saves on upper body manufacturing processes while minimizing the difficulty of chassis manufacturing, thus improving the production efficiency of the upper body.

[0007] In some embodiments, prior to the step of assembling the vehicle body and chassis, the vehicle production method further includes: fabricating an mounting structure on the chassis; the step of assembling the vehicle body and chassis includes: mounting the upper body to the chassis via the mounting structure.

[0008] The technical solution of this embodiment provides steps for manufacturing an installation structure. By setting the installation structure on the chassis, the chassis can be matched with the upper body, and the upper body can be more easily installed on the chassis.

[0010] In the technical solution of this embodiment, the position, shape, and other structures of the mounting structure on the chassis can be set according to the different vehicle models corresponding to the chassis, so that the chassis with the same structure can be used to match the upper body of different vehicle models through different mounting structures; at the same time, during the chassis processing, there is no need to adjust the production line, production equipment, production cycle, etc. for different vehicle models, which improves the chassis's adaptability and reduces the negative impact of vehicle model changes on chassis processing.

[0011] In some embodiments, the steps of manufacturing the chassis include: connecting the pillar outer plate and the sill structure to the chassis frame; and installing at least one of the following on the chassis frame: a suspension system, a steering system, a braking system, a transmission system, a chassis electrical control system, and an energy storage system.

[0019] In some embodiments, the step of manufacturing the upper body, prior to the step of installing the electrical structure, further includes painting the body-in-white.

[0020] The technical solution of this embodiment provides some steps for manufacturing the upper body. Before the electrical structure is installed, the body-in-white is first painted to meet the requirements of corrosion resistance and appearance of the upper body. At the same time, painting before the electrical structure is installed can also reduce the damage to the electrical structure that may be caused during the painting process.

[0021] In some embodiments, the vehicle production method further includes: fabricating a door cover structure, wherein the door cover structure includes at least one of a door, a hood, and a tailgate; after the step of assembling the vehicle body and chassis, the vehicle production method further includes: installing the door cover structure.

[0026] The chassis includes a chassis frame and pillar outer panels and sill structures connected to the chassis frame; the upper body includes a roof structure and pillars connected to the roof structure, the pillars being connected to the pillar outer panels or sill structures via connecting structures.

[0027] In this embodiment, the pillar outer panel and sill structure are mounted on the chassis frame, so that the upper body no longer includes the pillar outer panel and sill structure, reducing the structure in the upper body and simplifying the upper body manufacturing process. Regarding the chassis processing, since the chassis itself has a complex structure, it is difficult to cut corners in the various chassis processes. Therefore, by mounting the pillar outer panel and sill structure on the chassis frame and processing them using the chassis's processing equipment, the existing processes, equipment, and workshops of the chassis can be utilized without adding additional processes. In other words, this embodiment saves on the upper body processing steps without increasing the difficulty of chassis processing, thus improving the production efficiency of the upper body.

[0083] In vehicle production, the upper body and chassis are typically manufactured in separate workshops and then assembled together in the final assembly workshop to form the complete vehicle. Within a vehicle, the chassis not only supports the body and onboard systems but also plays a crucial role in the vehicle's handling, stability, and safety. Therefore, chassis manufacturing is generally complex, involving numerous structural components. The chassis manufacturing process typically includes welding, painting, and final assembly; among these, the welding process is particularly important in ensuring sufficient strength for the chassis.

[0084] The current upper body typically includes pillars (such as front pillars, center pillars, and rear pillars), a roof structure, pillar outer panels, and sill structures. Among these, the pillar outer panels and sill structures are the main structures in the upper body connected to the chassis; the pillar outer panels primarily provide structural support, enhance pillar rigidity, and improve safety performance; the sill structures primarily provide support along the vehicle's length and lateral direction, dispersing collision energy and improving safety performance.

[0085] Current upper body manufacturing processes typically include welding, painting, and final assembly. The current upper body structure is also quite complex, with components such as pillars, outer panels, sill structures, and pillars all serving to provide support and enhance vehicle strength; therefore, welding is difficult to omit in the upper body manufacturing process. This results in a cumbersome and difficult-to-optimize upper body manufacturing process, leading to low production efficiency and high costs.

[0086] Based on the above considerations, in order to improve the production efficiency of the upper body and alleviate the current problem of low production efficiency of the upper body, this application provides a vehicle production method. In this method, the outer pillar plate and the sill structure are installed on the chassis structure, that is, the welding and other processing steps of the outer pillar plate and the sill structure can be completed in the chassis workshop. At this time, the processing of the upper body mainly includes the connection of the pillar and the roof structure, which greatly simplifies the structure of the upper body. On this basis, the processing of the upper body is not limited to welding, and can also adopt one-piece molding or other processing methods depending on the material of the upper body.

[0087] In this vehicle production method, the outer pillar panels and sill structures are installed on the chassis frame, utilizing the chassis's own processing procedures, equipment, and space (such as the workshop). This method has minimal negative impact on the chassis processing, does not increase the processing difficulty of the chassis, greatly simplifies the processing procedures of the upper body, saves processing procedures and time for the upper body, and improves the processing efficiency of the upper body.

[0088] To illustrate the technical solutions described in this application, the following description is provided in conjunction with specific accompanying drawings and embodiments.

[0089] Firstly, reference Figure 1 This application provides a method for producing a vehicle 10, comprising:

[0090] S100: Chassis manufacturing 11.

[0091] In this step, the outer panel 112 of the column and the sill structure 113 are installed on the chassis frame 111.

[0092] The chassis frame 111 refers to the main support structure of the vehicle 10. The chassis frame 111 can be connected to the front and rear axles of the vehicle 10. The chassis frame 111 can be a frame structure and includes multiple longitudinal beams and transverse beams. The chassis frame 111 is mainly used to provide the mounting foundation and support for other structures of the vehicle 10, and to bear various loads inside and outside the vehicle 10.

[0093] The pillar outer plate 112 refers to the structure in the vehicle 10 located between the pillar 122 and the chassis frame 111. The pillar outer plate 112 can provide support for the pillar 122, improve the strength of the pillar 122, enhance the overall rigidity and torsional resistance of the vehicle 10, and withstand most of the collision energy in a side collision.

[0094] One side of the pillar outer plate 112 is connected to the chassis frame 111. The pillar outer plate 112 can be connected to the chassis frame 111 by welding or other means. The other side of the pillar outer plate 112 is used to connect to the pillar 122 of the upper body 12. Depending on the number of pillars 122 of the upper body 12, the number of pillar outer plates 112 can be one, two or more. Depending on the arrangement of the pillars 122 of the upper body 12, the pillar outer plates 112 can be arranged on both sides of the chassis 11 facing the upper body 12 along the width direction of the vehicle 10, and the pillar outer plates 112 can be arranged at intervals along the length direction of the vehicle 10.

[0095] The sill structure 113 is part of the frame structure of the vehicle 10. The sill structure 113 is located below the door and is mainly used to improve the rigidity of the vehicle 10. In the event of a collision, the sill structure 113 can guide and disperse the collision energy, thereby working with the pillar 122 to provide protection for the occupants. At the same time, the sill structure 113 can also block mud, stones and other impurities from the road surface.

[0096] One side of the sill structure 113 is connected to the chassis frame 111. The sill structure 113 can be connected to the chassis frame 111 by welding or by other means. The other side of the sill structure 113 can be connected to the pillar 122 of the upper body 12 or to the pillar outer plate 112. The sill structure 113 can be provided on both sides of the chassis 11 facing the upper body 12 along the width direction of the vehicle 10.

[0097] In this step, the processing and installation of the column outer panel 112 and the sill structure 113 are both included in the chassis 11 processing step. In the processing scenario, the processing and installation of the column outer panel 112 and the sill structure 113 can be completed in the same workshop as other processing and installation of the chassis 11 structure.

[0098] S200: Build the upper body 12.

[0099] In this step, the pillar 122 is connected to the roof structure 121 to form the main structure of the upper body 12.

[0100] The pillar 122 refers to the structure in the vehicle 10 used to support the roof structure 121. One end of the pillar 122 is connected to the chassis 11, and the pillar 122 can be connected to the pillar outer panel 112, the sill structure 113, or other structures of the chassis 11. The other end of the pillar 122 is connected to the top structure to support the top mechanism. The pillar 122 can also provide support for the cabin and improve the rigidity of the vehicle 10, thus protecting the occupants. Depending on the different models of the vehicle 10, the number of pillars 122 can be one, two, or more.

[0101] The roof structure 121 refers to the top structure of the vehicle 10. The roof structure 121 is connected to the side of the pillar 122 away from the chassis 11. The roof structure 121 can cooperate with the chassis 11 to form the cabin of the vehicle 10, providing passengers with seating space and protection. At the same time, the roof structure 121 can also improve the overall rigidity of the vehicle 10.

[0102] In this step, the pillar 122 is connected to the roof structure 121. The pillar 122 can be connected to the roof structure 121 by welding or other means. The pillar 122 can also be integrally formed with the roof structure 121. Since the pillar outer plate 112 and the sill structure 113 are located on the chassis 11, the structure of the upper body 12 is relatively simple and the integral forming is less difficult.

[0103] For example, when the materials of the pillar 122 and the roof structure 121 include composite materials, the pillar 122 and the roof structure 121 can be manufactured by an integral molding process. The composite materials can include fiber-reinforced composite materials (such as glass fiber reinforced composite materials, carbon fiber reinforced composite materials), particulate composite materials, laminated composite materials, etc. In this case, there is no need to set up welding, electrophoresis and other processes in the processing of the upper body 12, nor is it necessary to set up corresponding welding workshops, welding equipment, electrophoresis equipment, etc., which simplifies the process, improves efficiency and saves costs.

[0104] S500: Assemble the upper body 12 and chassis 11.

[0105] In this step, the upper body 12 and the chassis 11 are assembled and fixed. The upper body 12 is fixed to the chassis 11 mainly by the support column 122. The support column 122 can be fixed to the outer panel 112 of the support column, the sill structure 113 or other structures, or the support column 122 can be directly fixed to the bracket of the chassis 11. Depending on the material of the support column 122 and the connected structure, the support column 122 can be fixed to the chassis 11 by welding, screwing or other structures.

[0106] In this embodiment, the pillar outer plate 112 and the sill structure 113 are mounted on the chassis frame 111. Simultaneously, during the processing of the upper body 12, the pillar 122 and the roof structure 121 are primarily connected, so that the upper body 12 no longer includes the pillar outer plate 112 and the sill structure 113, reducing the structure in the upper body 12 and simplifying the processing steps. Regarding the chassis 11 processing, because the chassis 11 itself has a relatively complex structure, it is difficult to save on the various processes of the chassis 11. Therefore, the pillar outer plate 112 and the sill structure 113 are mounted on the chassis frame 111 and processed using the chassis 11's processing equipment. This allows the chassis 11 to utilize its own processing steps, equipment, and workshops without adding additional steps. In other words, this embodiment saves on the processing steps of the upper body 12 while also minimizing the difficulty of processing the chassis 11, thus improving the production efficiency of the upper body 12.

[0107] Among the current manufacturers of vehicles 10, there are manufacturers that independently produce and assemble both the upper body 12 and the chassis 11, as well as manufacturers that independently produce the chassis and then assemble the upper body 12 after purchasing it.

[0108] For manufacturers that independently produce and assemble both the upper body 12 and the chassis 11, the vehicle 10 production method provided in this application embodiment can reduce the number of processes required in the upper body 12 processing, reduce the processing difficulty of the upper body 12 and save processing time, thereby improving processing efficiency; at the same time, it can also save the equipment, workshops, and labor required for the processing of the upper body 12, thereby reducing production costs.

[0109] For structural manufacturers that only produce chassis 11, the vehicle 10 production method provided in this application embodiment can reduce the structural complexity of the upper body 12, reduce the difficulty for suppliers to manufacture the upper body 12, thereby reducing the product defect rate of the upper body 12 and facilitating product quality control; at the same time, it can also reduce the cost for suppliers to manufacture the upper body 12 and reduce procurement costs.

[0110] refer to Figure 2 In some embodiments, before the step of assembling the body 12 and chassis 11, that is, before step S500, the vehicle 10 production method further includes:

[0111] S300: Install the mounting structure 115 on the chassis 11.

[0112] Mounting structure 115 refers to the structure on chassis 11 used to mate with upper body 12. Upper body 12 can be fixed to chassis 11 via mounting structure 115. Depending on the mounting position of upper body 12 and the structure of chassis 11, mounting structure 115 can be provided on pillar outer panel 112, sill structure 113, chassis frame 111 or other structures. Mounting structure 115 can include hole structures provided on corresponding structures of chassis 11, or it can be a snap-fit ​​structure or other structures. It is understood that, depending on the specific structure of mounting structure 115, upper body 12 can be mounted on mounting structure 115 by bolts, clamps or other structures, or it can be fixed on mounting structure 115 by welding or other means.

[0113] Depending on the different models of the upper body 12, the mounting structure 115 can be set in different structures or different positions of the chassis 11. For example, since the structures of the upper body 12 of different models corresponding to the chassis 11 are usually similar and the differences are small, the mounting structure 115 can be set in different positions of the same structural component according to the different models of the upper body 12, such as in different positions of the outer panel 112 of the pillar.

[0114] Depending on the different models of the upper body 12, the mounting structure 115 can also be configured with different structures; for example, when the mounting structure 115 is a hole structure, the mounting structure 115 can be a square hole, a round hole, a triangular hole, or a hole structure of other shapes.

[0115] The steps of assembling the upper body 12 and the chassis 11, that is, the steps in S500, include: mounting the upper body 12 onto the chassis 11 by means of the mounting structure 115.

[0116] In step S500, the upper body 12 is mounted on the chassis 11 via the mounting structure 115. Since the mounting structure 115 is located on the chassis 11, the upper body 12 can be directly connected to the mounting structure 115 and indirectly connected to the chassis 11 via the mounting structure 115. The upper body 12 can also be connected to both the mounting structure 115 and the chassis 11 simultaneously, so as to improve the connection stability between the upper body 12 and the chassis 11 via the mounting structure 115, or to play a positioning role via the mounting structure 115.

[0117] For example, the mounting structure 115 is a hole structure. The mounting structure 115 is set on the outer plate of the pillar 112 and the sill structure 113. The pillar 122 of the upper body 12 is fixed to the corresponding outer plate of the pillar 112 or the sill structure 113 by bolts and the hole structure.

[0118] This embodiment provides steps for manufacturing the mounting structure 115. By setting the mounting structure 115 on the chassis 11, the chassis 11 can be matched with the upper body 12, and the upper body 12 can be more easily installed on the chassis 11.

[0119] refer to Figure 3 In some embodiments, the step of fabricating the mounting structure 115 on the chassis 11, i.e., in step S300, includes:

[0120] S310: Identify the vehicle model information corresponding to chassis 11.

[0121] In this step, vehicle model information refers to information such as the processing time, vehicle configuration, and body parameters corresponding to chassis 11. Since the processing time and vehicle configuration of chassis 11 are predetermined before processing, each chassis 11 has corresponding vehicle model information. This step is mainly used to obtain the vehicle model information corresponding to the chassis 11.

[0122] Vehicle information can be recorded by a QR code, barcode or other graphic affixed to the chassis 11, or by encoding the chassis 11 or other methods; depending on the method of recording the vehicle information, the identification device can be a camera, or a QR code, barcode scanning device or other device.

[0123] S320: The corresponding mounting structure 115 is processed according to the vehicle model information.

[0124] Since the vehicle model information records the model of the upper body 12 corresponding to the chassis 11, the mounting structure 115 corresponding to the chassis 11 is also determined when the chassis 11 and the upper body 12 are determined. Accordingly, in this step, the position, structure and other information of the mounting structure 115 can be determined by the vehicle model information identified in step S310, and the corresponding mounting structure 115 is processed on the chassis 11 based on this information, so that the chassis 11, the mounting structure 115 and the upper body 12 can correspond to each other, so as to facilitate installation and assembly.

[0125] Understandably, in this step, the chassis 11 adapts to different upper body 12 through different mounting structures 115. That is, before steps S310 and S320, the processing steps of the chassis 11 do not need to be changed according to the different upper body 12. Correspondingly, the production line, production equipment, production cycle of the chassis 11 do not need to be adjusted, so that the same chassis 11 production line can process chassis 11 of different models, reducing the negative impact of model changes on the processing procedures and production equipment of the chassis 11.

[0126] In this embodiment, the position, shape, and other structures of the mounting structure 115 on the chassis 11 can be set according to the different vehicle models corresponding to the chassis 11, so that the chassis 11 with the same structure can be used to correspond to the upper body 12 of different vehicle models through different mounting structures 115; at the same time, during the processing of the chassis 11, there is no need to adjust the production line, production equipment, production cycle, etc. for different vehicle models, which improves the adaptability of the chassis 11 and reduces the negative impact of vehicle model changes on the processing of the chassis 11.

[0127] refer to Figure 3 In some embodiments, the step of manufacturing chassis 11, i.e., step S100, includes:

[0128] S110: Connect the column outer plate 112 and the sill structure 113 to the chassis frame 111.

[0129] In this step, the outer plate 112 of the pillar and the sill structure 113 are connected to the chassis frame 111. The outer plate 112 of the pillar and the sill structure 113 can be connected to the chassis frame 111 by welding or by other means.

[0130] After the column outer plate 112 and the sill structure 113 are connected to the chassis frame 111, the chassis frame 111 and the structure thereon can be painted.

[0131] S120: Install at least one of the following on the chassis frame 111: suspension system, steering system, braking system, transmission system, chassis electrical control system, and energy storage system.

[0132] In this step, the suspension system refers to the structure in the chassis 11 used to buffer the impact load on the chassis 11 due to uneven road surface. The suspension system can also buffer the vibration caused by this, reduce the vibration of the vehicle 10 itself, and maintain the contact between the tires and the ground. The suspension system can also control the attitude of the vehicle 10 to reduce the risk of excessive tilting or swaying of the vehicle 10.

[0133] The steering system refers to the structure in the chassis 11 used to control the steering of the wheels and the direction of travel of the vehicle 10. The steering system can both change the way the vehicle 10 travels and maintain the direction of travel of the vehicle 10.

[0134] The braking system refers to the structure in the chassis 11 used for deceleration. The braking system can decelerate or stop the vehicle 10 during its operation. The braking system can also maintain the speed of the vehicle 10 when it is going downhill, thereby improving the handling, stability and safety of the vehicle 10.

[0135] The transmission system refers to the structure in the chassis 11 used to transmit power. The transmission system can transmit power from the engine or electric motor to the wheels. The transmission system may include structures such as clutch, gearbox, drive shaft, reducer, differential, and half shaft.

[0136] The chassis electrical control system refers to the control structure in the chassis 11 used to control the electrical equipment on the chassis 11. 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 11 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 11.

[0137] An energy storage system refers to a structure in the chassis 11 used to supply power to the vehicle 10. The energy storage system may include a battery device or other energy storage device to provide electrical energy to the electric motor or engine of the vehicle 10.

[0138] Depending on the different vehicle models corresponding to the chassis 11, one or more of the following systems can be installed on the chassis frame 111: suspension system, steering system, braking system, transmission system, chassis electrical control system, and energy storage system.

[0139] This embodiment provides some specific steps for processing the chassis 11, and installing different systems of the vehicle 10 on the chassis frame 111 so that the vehicle 10 can have various corresponding functions.

[0140] In some embodiments, the step of manufacturing the chassis 11, that is, the step of S100, further includes: connecting the front bulkhead structure and the floor structure to the chassis frame 111.

[0141] If step S100 includes step S110, step S110 may include connecting the front bulkhead structure and floor structure to the chassis frame 111, that is, the front bulkhead structure and floor structure may be connected to the chassis frame 111 in the same step as the pillar outer panel 112 and the sill structure 113.

[0142] In this step, the front bulkhead structure refers to the structure in vehicle 10 used to separate the front of the vehicle body from the passenger compartment. The front of the vehicle body refers to the space in vehicle 10 used to store the engine or other structures, and the passenger compartment refers to the space in vehicle 10 used to accommodate occupants. The front bulkhead structure also supports the windshield and steering column, increases the rigidity of vehicle 10, prevents structural components from intruding into the passenger compartment in the event of a frontal collision of vehicle 10, and prevents flames from intruding into the passenger compartment in the event of a fire in the front of vehicle 10.

[0143] The front bulkhead structure is connected to the chassis frame 111. The front bulkhead structure can be connected to the chassis frame 111 by welding or other means.

[0144] The floor structure refers to the structure in vehicle 10 used to support passengers or cargo. The floor structure can also improve the rigidity of vehicle 10 and provide an installation base for structures such as energy storage systems, seats, and floor beams.

[0145] The floor structure is connected to the chassis frame 111, and the floor structure can be connected to the chassis frame 111 by welding or other means.

[0146] The current upper body 12 typically includes a front structure (such as the front upper panel) and a floor structure (such as the rear floor), while other parts of the front and floor structures are usually mounted on the chassis 11. During the assembly of the upper body 12 and the chassis 11, the front and floor structures of the upper body 12 and the floor structure also need to be assembled and connected. This makes the assembly process of the upper body 12 and the floor structure more complicated and prone to installation errors that affect the structural strength and stability.

[0147] Accordingly, in this embodiment, the front bulkhead structure and / or floor structure are also mounted on the chassis frame 111, which can further reduce the structure of the upper body 12, thereby saving the processing steps of the upper body 12 and improving the production efficiency of the upper body 12; it can also reduce the installation error of the front bulkhead structure and floor structure, thereby reducing the negative impact on the structural strength and stability of the front bulkhead structure and floor structure.

[0148] In some embodiments, during the step of manufacturing the upper body 12, that is, during step S200, the pillar 122 includes at least one of the front pillar 1221, the middle pillar 1222, and the rear pillar 1223.

[0149] The front pillar 1221 refers to the pillars 122 located on both sides of the windshield in the vehicle 10. The front pillar 1221 connects the left and right front of the roof structure 121 to the chassis 11. The front pillar 1221 supports the roof structure 121 and the windshield, and improves the overall rigidity of the vehicle 10. In the event of a collision, the front pillar 1221 can also absorb collision energy to protect the occupants. For example, the side of the front pillar 1221 facing away from the roof structure 121 can be directly connected to the pillar outer panel 112, or the side of the front pillar 1221 facing away from the roof structure 121 can be connected to the mounting structure 115 on the pillar outer panel 112.

[0150] The center pillar 1222 refers to the pillar 122 located between the front and rear doors in the vehicle 10. The center pillar 1222 supports the roof structure 121 and improves the overall rigidity of the vehicle 10. In the event of a collision, especially a side collision, the center pillar 1222 can absorb collision energy to protect the occupants. For example, the side of the center pillar 1222 facing away from the roof structure 121 can be directly connected to the sill structure 113, or the side of the center pillar 1222 facing away from the roof structure 121 can be connected to the mounting structure 115 on the sill structure 113.

[0151] The rear pillar 1223 refers to the pillars 122 located on both sides of the rear windshield in the vehicle 10. The rear pillars 1223 support the roof structure 121 and the rear windshield, and improve the overall rigidity of the vehicle 10. In the event of a collision, especially a rear-end collision, the rear pillars 1223 can absorb collision energy to protect the occupants. For example, the side of the rear pillar 1223 facing away from the roof structure 121 can be directly connected to the chassis 11 bracket, or it can be connected to other structures of the chassis 11, or to the mounting structure 115.

[0152] Depending on the different vehicle models 10, the pillars 122 of the upper body 12 may include only one of the front pillars 1221, the middle pillars 1222 or the rear pillars 1223, or any two or three.

[0153] This embodiment provides some specific structures for the pillars 122, such that the pillars 122 include at least one of the front pillar 1221, the middle pillar 1222, and the rear pillar 1223, so that the pillars 122 can better support the roof structure 121 and the entire vehicle 10.

[0154] refer to Figure 5 In some embodiments, the step of manufacturing the upper body 12, i.e., step S200, includes:

[0155] S210: Connect the pillar 122 to the roof structure 121 to form the body-in-white;

[0156] The body-in-white refers to the unpainted structure of the upper body 12 after the various structural components are assembled. The body-in-white in this step mainly includes the pillars 122 and the roof structure 121.

[0157] In this step, the column 122 is connected to the corresponding position of the top cover structure 121 according to the specific structure of the column 122; for example, the front column 1221 is located at the front left and front right of the top cover structure 121, the middle column 1222 is located at the middle of the two sides of the width direction of the top cover structure 121, and the rear column 1223 is located at the rear left and rear right of the top cover structure 121.

[0158] The column 122 can be connected to the top cover structure 121 by welding or other means, or the column 122 can be integrally formed with the top cover structure 121.

[0159] When the chassis 11 includes pillar outer panel 112, sill structure 113, front bulkhead structure and floor structure, the body-in-white may only include pillar 122 and roof structure 121, and the structure of the body-in-white is relatively simple.

[0160] S230: Install electrical structures on the white body.

[0161] In this step, the electrical structure refers to the electrical structure of the upper body 12, including electronic components such as wiring harnesses and sensors; the electrical structure may also include other electrical structures such as interior lights and electric sunroofs.

[0162] This embodiment provides some steps for manufacturing the upper body 12 so that the upper body 12 can have a certain strength and support performance, as well as corresponding electrical performance.

[0163] refer to Figure 5 In some embodiments, the step of manufacturing the upper body 12, i.e., step S200, further includes:

[0164] S220: Paint treatment is applied to the body-in-white.

[0165] In this step, the painting treatment of the body-in-white refers to the process of applying rust and corrosion protection to the body-in-white. Simultaneously, the painting treatment can also help improve the strength of the body-in-white and provide some sound insulation and vibration reduction effects. The painting treatment of the body-in-white can include one or more processes such as pretreatment, electrophoretic coating, and topcoat application.

[0166] Pretreatment refers to the steps of removing impurities such as oil, dust, and welding slag from the surface of the car body. This can be achieved through methods such as degreasing, cleaning, and phosphating.

[0167] Electrophoretic coating refers to the process of applying electrophoretic paint to the surface of a car body in white, so as to form a relatively uniform, full, flat and smooth high-quality electrophoretic paint layer on the car body.

[0168] Topcoat coating refers to the process of applying a topcoat over the electrophoretic paint layer formed by electrophoretic coating to improve the weather resistance, water resistance, abrasion resistance, and other properties of the body-in-white. Topcoat coating can include the application of topcoat, color paint, and clear coat.

[0169] Step S220 is set before step S230 to reduce the potential damage to the electrical structure caused by the painting process.

[0170] This embodiment provides some steps for manufacturing the upper body 12. Before the electrical structure is installed, the body-in-white is painted to meet the requirements of corrosion resistance and appearance of the upper body 12. At the same time, painting before the electrical structure is installed can also reduce the damage to the electrical structure that may be caused during the painting process.

[0171] refer to Figure 6 In some embodiments, the method for producing vehicle 10 further includes:

[0172] S400: Fabrication of door cover structure.

[0173] In this step, the door cover structure includes at least one of a door, a front cover, and a tailgate.

[0174] After the steps of assembling the body 12 and chassis 11, that is, after the S500 steps, the production method of vehicle 10 also includes:

[0175] S600: Installation door cover structure.

[0176] In this step, the door cover structure is part of the external covering of the vehicle 10. The door cover structure may include structures such as doors, front covers (e.g., engine hoods), and tailgates (e.g., trunk lids). The door cover structure is used to protect the internal structure and occupants of the vehicle 10 to reduce the negative impact of the external environment on the internal structure and occupants of the vehicle 10. The door cover structure can also provide protection in the event of a side collision or rollover of the vehicle 10, dispersing collision energy and reducing the potential damage to the internal structure and occupants of the vehicle 10.

[0177] After the upper body 12 is installed on the chassis 11, the door cover structure can be installed on the upper body 12 or the chassis 11, or it can be connected to both the upper body 12 and the chassis 11 at the same time; for example, the door cover structure can be connected to the front bulkhead structure, the pillar 122 structure, the pillar outer panel 112 or other structures.

[0178] In this embodiment, the processing steps of vehicle 10 also include manufacturing a door cover structure to improve the safety performance and sound insulation performance of vehicle 10.

[0179] In some embodiments, the step of manufacturing the door cover structure, i.e., step S400, further includes: painting the door cover structure.

[0180] In this step, the coating treatment of the door cover structure refers to the process of applying rust and corrosion protection to the door cover structure. Simultaneously, the coating treatment can also help improve the strength of the door cover structure and provide some sound insulation and vibration reduction effects. The coating treatment of the door cover structure may include one or more processes such as pretreatment, electrophoretic coating, and topcoat coating.

[0181] Pretreatment refers to the process of removing impurities such as oil, dust, and welding slag from the surface of the door cover structure. This can be achieved through methods such as degreasing, cleaning, and phosphating.

[0182] Electrophoretic coating refers to the process of applying electrophoretic paint to the surface of a door cover structure to form a relatively uniform, full, flat, and smooth high-quality electrophoretic paint layer on the door cover structure.

[0183] Topcoat coating refers to the process of applying a topcoat over the electrophoretic paint layer formed by electrophoretic coating to improve the weather resistance, water resistance, and abrasion resistance of the door cover structure. Topcoat coating can include the application of topcoat, color paint, and clear coat.

[0184] In this step, after the door cover structure is painted, structures such as windows, window lifters, and door locks can be installed on the door cover structure, and wiring harnesses can be laid inside the door cover structure.

[0185] This embodiment provides some steps for manufacturing a door cover structure, including coating the door cover structure to improve its corrosion resistance and wear resistance, while also meeting the appearance requirements of the door cover structure.

The chassis 11 includes a chassis frame 111 and pillar outer plates 112 and sill structures 113 connected to the chassis frame 111; the upper body 12 includes a roof structure 121 and pillars 122 connected to the roof structure 121, the pillars 122 being connected to the pillar outer plates 112 or the sill structures 113 via connecting structures.

[0187] Similar to some embodiments of the first aspect, the chassis frame 111 refers to the main support structure of the vehicle 10; the pillar outer panel 112 refers to the structure in the vehicle 10 located between the pillar 122 and the chassis frame 111; the sill structure 113 refers to a part of the frame structure of the vehicle 10, and the sill structure 113 is located below the door.

[0188] One side of the pillar outer plate 112 is connected to the chassis frame 111. The pillar outer plate 112 can be connected to the chassis frame 111 by welding or other means. The other side of the pillar outer plate 112 is used to connect to the pillar 122 of the upper body 12.

[0189] One side of the sill structure 113 is connected to the chassis frame 111. The sill structure 113 can be connected to the chassis frame 111 by welding or by other means. The other side of the sill structure 113 can be connected to the pillar 122 of the upper body 12 or to the pillar outer plate 112.

Depending on the different models of the vehicle 10, the number of pillars 122 can be one, two, or more.

[0192] The roof structure 121 is connected to the side of the pillar 122 away from the chassis 11. The roof structure 121 can cooperate with the chassis 11 to form the cabin of the vehicle 10, providing passengers with seating space and protection. At the same time, the roof structure 121 can also improve the overall rigidity of the vehicle 10.

[0193] In this embodiment, the pillar outer plate 112 and the sill structure 113 are mounted on the chassis frame 111, so that the upper body 12 no longer includes the pillar outer plate 112 and the sill structure 113, reducing the structure in the upper body 12 and thus simplifying the processing steps of the upper body 12. As for the chassis 11 processing, since the chassis 11 itself has a relatively complex structure, it is difficult to save on the various processes of the chassis 11. Therefore, the pillar outer plate 112 and the sill structure 113 are mounted on the chassis frame 111 and processed by the processing equipment of the chassis 11. This allows the chassis 11 to process its own existing processes, equipment, workshops, etc., without adding additional processes. That is, this embodiment saves the processing steps of the upper body 12, and at the same time, it does not easily increase the processing difficulty of the chassis 11, thus improving the production efficiency of the upper body 12.

[0197] In this embodiment, the front bulkhead structure and / or floor structure are also located on the chassis frame 111, thereby further reducing the structure of the upper body 12, so as to better save the processing steps of the upper body 12 and improve the production efficiency of the upper body 12.

[0198] In some embodiments, the column 122 includes at least one of the front column 1221, the middle column 1222, and the rear column 1223.

The wheel cover outer plate 114 is connected to the chassis frame 111. The wheel cover outer plate 114 can be connected to the chassis frame 111 by welding or other means.

[0204] In this embodiment, the chassis 11 also includes a wheel cover outer plate 114 to cover the tires, thereby protecting the tires and reducing air resistance.

[0205] Thirdly, refer to Figure 9 Some embodiments of this application provide a vehicle 10 production line, which is applied to the vehicle 10 production method provided in some embodiments of the first aspect, or for producing the vehicle 10 provided in some embodiments of the second aspect.

[0206] The vehicle production line 10 includes an upper body processing area 200, a chassis processing area 300, and a final assembly area 400.

[0209] The upper body processing area 200 is used by workers to manufacture the upper body 12 using the upper body 12 processing equipment. The forming, welding, painting and other processes of the upper body 12 can all be completed in the upper body processing area 200.

[0210] The chassis processing area 300 refers to the area used to manufacture the chassis 11. The chassis processing area 300 can be a set spatial area or a spatial area enclosed by structural components. For example, the chassis processing area 300 is a processing area formed in the workshop, that is, the chassis processing area 300 is the chassis 11 processing workshop.

[0211] The chassis 11 processing equipment group is located in the chassis processing area 300 to facilitate the manufacturing of chassis 11. The chassis 11 processing equipment group may include a variety of different equipment. Depending on the different processes of chassis 11 processing, the chassis 11 processing equipment group may include welding equipment, painting equipment, transfer equipment, etc.

[0212] The chassis processing area 300 is used by workers to manufacture the chassis 11 using the chassis 11 processing equipment. The chassis 11 forming, welding, painting and other processes can all be completed in the chassis processing area 300.

[0213] It is understandable that, since the vehicle 10 production line is applicable to the vehicle 10 production method provided in some embodiments of the first aspect, or the vehicle 10 provided in some embodiments of the second aspect, the upper body 12 processed in the upper body processing area 200 mainly includes pillars 122 and roof structure 121, while the chassis 11 processed in the chassis processing area 300 includes pillar outer panels 112, sill structure 113 and other structures.

[0214] The final assembly area 400 refers to the area used to assemble the body 12 and the chassis 11.

For example, the final assembly area 400 is a processing area formed in the workshop, that is, the final assembly area 400 is the final assembly workshop.

[0215] The final assembly area 400 is used by workers to install the upper body 12 onto the chassis 11. Welding, bolting, and other processes between the upper body 12 and the chassis 11 can all be completed in the final assembly area 400.

[0216] Since the final assembly area 400 is used for mounting the upper body 12 onto the chassis 11, that is, the final assembly area 400 is located downstream of the upper body processing area 200 and the chassis processing area 300, so as to facilitate the assembly of the upper body 12 and the chassis 11.

[0217] In this embodiment, the upper body 12 and the chassis 11 are machined separately and assembled in the final assembly area 400, so as to improve the efficiency of vehicle 10 machining and assembly.

[0218] refer to Figure 9In some embodiments, the chassis processing area 300 includes a first chassis processing station 310, and the chassis 11 processing equipment group includes a mounting structure 115 processing equipment. The mounting structure 115 processing equipment is used to fabricate the mounting structure 115 on the chassis 11 within the first chassis processing station 310. The mounting structure 115 is configured to connect to the upper body 12.

[0219] Similar to some embodiments of the first aspect, the mounting structure 115 refers to a structure on the chassis 11 for engaging with the upper body 12. The upper body 12 can be fixed to the chassis 11 via the mounting structure 115. Depending on the mounting position of the upper body 12 and the structure of the chassis 11, the mounting structure 115 can be provided on the outer panel of the pillar 112, the sill structure 113, the chassis frame 111, or other structures. The mounting structure 115 may include a hole structure provided on the corresponding structure of the chassis 11, or it may be a snap-fit ​​structure or other structures.

[0220] Depending on the different models of the upper body 12 corresponding to the chassis 11, the position and structure of the mounting structure 115 can also be different, so that the chassis 11 can adapt to different upper bodies 12 through different mounting structures 115. The processing of the chassis 11 does not need to be changed according to the different upper bodies 12. Correspondingly, the production line, production equipment, production cycle of the chassis 11 do not need to be adjusted, so that the same chassis 11 production line can process chassis 11 of different models, reducing the negative impact of model changes on the processing procedures and production equipment of chassis 11.

[0221] The first chassis processing station 310 refers to the spatial structure in the chassis processing area 300. The first chassis processing station 310 can be a set space or a space enclosed by structural components.

[0225] The second chassis processing station 320 refers to the spatial structure in the chassis processing area 300. The second chassis processing station 320 can be a set space or a space enclosed by structural components. A recognition device is provided on one side of the second chassis processing station 320 to identify the vehicle model information corresponding to the chassis 11, so as to process the corresponding mounting structure 115.

[0226] Vehicle model information refers to information such as the processing time of chassis 11, vehicle configuration of vehicle 10, and body parameters. Since the processing time and vehicle configuration of chassis 11 are predetermined before processing, each chassis 11 has corresponding vehicle model information. Vehicle model information can be recorded by a QR code, barcode, or other graphic affixed to chassis 11, or by chassis 11 coding or other methods. Depending on the method of recording vehicle model information, the identification device can be a camera, a QR code or barcode scanning device, or other devices.

[0227] Since the vehicle model information records the model of the upper body 12 corresponding to the chassis 11, the mounting structure 115 corresponding to the chassis 11 is also determined when the chassis 11 and the upper body 12 are determined. Accordingly, the second chassis processing station 320 should be located before the first chassis processing station 310 so that the mounting structure 115 processing equipment can process the corresponding mounting structure 115 according to the vehicle model information identified by the identification equipment.

[0228] In this embodiment, the identification device identifies the vehicle model information corresponding to the chassis 11 within the second chassis processing station 320. This allows the position, shape, and other structures of the mounting structure 115 on the chassis 11 to be set according to the different vehicle model information corresponding to the chassis 11. As a result, the chassis 11 with the same structure can be used to correspond to the upper body 12 of different vehicle models through different mounting structures 115. At the same time, during the processing of the chassis 11, there is no need to adjust the production line, production equipment, production cycle, etc. for different vehicle models, which improves the adaptability of the chassis 11 and reduces the negative impact of vehicle model changes on the processing of the chassis 11.

That is, in the chassis processing area 300, the pillar outer plate 112 and the sill structure 113 are first connected to the chassis frame 111 in the third chassis processing station 330. Then, the processed chassis frame 111 is sent to the second chassis processing station 320 for the identification equipment to identify the vehicle model information corresponding to the chassis 11. After that, the identified chassis 11 is sent to the first chassis processing station 310 for the installation structure 115 to be made on the chassis 11.
