Technical Field

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

[0002] Battery devices have advantages such as high energy density and high power density, and are widely used in various industries. With the rapid development of the battery industry, the technology for using batteries as a power source for vehicles is becoming increasingly mature.

[0003] With the continuous development of electric vehicle technology, how to improve the production efficiency of electric vehicle chassis has attracted increasing attention from those skilled in the art. Summary of the Invention

[0004] In view of the above problems, this application provides a chassis production system and production method, which has high production efficiency.

[0005] In a first aspect, some embodiments of this application provide a chassis production system, which includes a transport device, a transfer device, and an assembly device. The transport device is used to carry and transfer an energy compartment, which includes a battery. The transfer device is used to transfer a front compartment and a rear compartment. The assembly device includes an assembly position for parking the transport device and is used to install the front compartment and the rear compartment at opposite ends of the energy compartment.

[0006] In the above scheme, since the transportation device in the chassis production system can carry the energy warehouse and transfer it to the assembly position of the assembly device for the installation of the front and rear warehouses, the repeated lifting of the energy warehouse from the transportation line during the chassis production process is reduced, the transfer time is reduced, and the production efficiency of the chassis is improved.

[0007] According to some embodiments of this application, the chassis production system includes an assembly device comprising a base, a moving component, and a drive mechanism. The base forms an assembly position, the moving component is movably connected to the base, and the drive mechanism is drively connected to the moving component to drive the moving component to move.

[0008] According to some embodiments of this application, the chassis production system includes a base comprising a first part and a second part disposed opposite to each other along a first direction, an assembly position being formed between the first part and the second part, and an inlet / outlet being provided at at least one end of the assembly position in a second direction, the second direction intersecting the first direction, such that a transport device carrying an energy chamber can enter the assembly position from the inlet / outlet, and a transport device carrying the assembled chassis can leave the assembly position from the inlet / outlet.

[0009] According to some embodiments of this application, the chassis production system includes a drive mechanism comprising a translation component and a lifting component. The translation component is driven to the moving part and can drive the moving part to clamp or disengage from the energy chamber.

[0010] According to some embodiments of this application, the chassis production system includes an assembly device comprising a front compartment positioning structure and a rear compartment positioning structure. The front compartment positioning structure positions the front compartment relative to the energy compartment, and the rear compartment positioning structure positions the rear compartment relative to the energy compartment. Through the front compartment positioning structure, after the transfer device moves the front compartment to the end of the energy compartment, the front compartment can be positioned relatively accurately within the energy compartment, ensuring relative positioning between the front compartment and the energy compartment. This reduces the possibility of movement of the front compartment relative to the energy compartment and facilitates subsequent connection and fixation of the front compartment to the energy compartment. Similarly, through the rear compartment positioning structure, after the transfer device moves the rear compartment to the end of the energy compartment, the rear compartment can be positioned relatively accurately within the energy compartment, ensuring relative positioning between the rear compartment and the energy compartment. This reduces the possibility of movement of the rear compartment relative to the energy compartment and facilitates subsequent connection and fixation of the rear compartment to the energy compartment.

The front compartment clamping mechanism is used to clamp the front compartment, the rear compartment clamping mechanism is used to clamp the rear compartment, and the energy compartment clamping mechanism is used to clamp the energy compartment. Through the front compartment clamping mechanism, after the transfer device positions the front compartment at the end of the energy compartment, the position of the front compartment can be kept relatively stable. Through the rear compartment clamping mechanism, after the transfer device positions the rear compartment at the end of the energy compartment, the position of the rear compartment can be kept relatively stable.

By mounting the pallet on top of the vehicle body, the vehicle body can transport the energy storage compartment via the pallet mounted on its top, making the transportation of the energy storage compartment more convenient.

[0013] According to some embodiments of the present application, the chassis production system includes a transport device comprising a locking mechanism capable of locking or unlocking a pallet.

[0057] With increasing emphasis on environmental protection, electric vehicles, which use battery devices as their power source, are being used more and more widely. As electric vehicle technology continues to develop, the production efficiency of electric vehicles is attracting increasing attention from those skilled in the art.

[0058] In related technologies, electric vehicle production systems are typically arranged in a long, narrow linear layout, with a large number of workstations arranged sequentially along a conveyor line. During the chassis production process, the chassis is usually divided into three sections: the energy compartment, the front compartment, and the rear compartment. These sections are assembled separately, and then reassembled on an assembly line. This process usually involves using lifting equipment to transport the energy compartment, front compartment, and rear compartment from the conveyor line to the workstations for assembly. Once the three sections are assembled to form the chassis, the chassis is then lifted back onto the conveyor line for transport to the next workstation. Because this production process requires repeated lifting, it is not only time-consuming but also disrupts the continuity of the conveyor line, hindering production efficiency.

[0059] To improve chassis production efficiency, some embodiments of this application provide a chassis production system. This system includes a transport device, a transfer device, and an assembly device. The transport device carries and transfers an energy storage compartment, which includes a battery. The transfer device transfers a front compartment and a rear compartment. The assembly device includes an assembly station for parking the transport device and for installing the front and rear compartments at opposite ends of the energy storage compartment. In this solution, because the transport device in the chassis production system can carry the energy storage compartment and transfer it to the assembly station of the assembly device for installing the front and rear compartments, the repeated lifting and lowering of the energy storage compartment from the transport line during chassis production is reduced, thus decreasing transfer time and improving chassis production efficiency.

[0060] The chassis production system disclosed in this application can be used, but is not limited to, for producing chassis for electric vehicles, and can also be used for producing chassis for fuel-powered vehicles and natural gas vehicles.

[0061] The technical solution of the chassis production system and production method provided in the specific embodiments of this application will be further described below.

[0062] Some embodiments of this application provide a chassis production system, such as Figure 1 As shown, the production system of the chassis includes a transport device 1, a transfer device (not shown in the figure) and an assembly device 3. The transport device 1 is used to carry and transfer the energy chamber 10, which includes a battery. The transfer device is used to transfer the front chamber 20 and the rear chamber 30. The assembly device 3 includes an assembly position 313 for parking the transport device 1. The assembly device 3 is used to install the front chamber 20 and the rear chamber 30 at both ends of the energy chamber 10, respectively.

[0063] The chassis of an electric vehicle typically comprises three parts: a front compartment 20, an energy compartment 10, and a rear compartment 30. The energy compartment 10 contains a battery that provides power to the electric vehicle. The front compartment 20 and the rear compartment 30 are respectively installed at opposite ends of the energy compartment 10. Specifically, the front compartment 20 may be installed at the front end of the energy compartment 10 in the direction of vehicle travel, and the rear compartment 30 may be installed at the rear end of the energy compartment 10 in the direction of vehicle travel.

[0064] The transport device 1 can be a device for carrying and transporting components of electric vehicles. It can transport the components of electric vehicles to the work station for operation, reducing the process of transferring components using equipment such as forklifts and lifting equipment.

[0065] By installing a transport device 1 in the chassis production system, the energy storage unit 10 can be carried and transferred directly to the assembly station 313. This reduces the need for lifting and other transfers of the energy storage unit 10 between the conveyor line and the assembly station 313, saving transfer time and improving the chassis production efficiency. For example, the transport device 1 may include a transport vehicle, transport pallet, or other device capable of carrying the energy storage unit 10.

[0066] The transfer device can be a means in the chassis production system for transferring electric vehicle components from a conveyor line to assembly station 313. The transfer device transfers the front compartment 20 and rear compartment 30 from the conveyor line to assembly station 313, allowing them to be installed onto the energy storage compartment 10 located at assembly station 313. Exemplarily, the transfer device may include lifting equipment, forklifts, or other means capable of transferring the energy storage compartment 10.

[0067] The assembly device 3 can be a device for mounting the front compartment 20 and the rear compartment 30 onto the energy compartment 10. It can assemble the energy compartment 10, the front compartment 20 and the rear compartment 30 into a chassis by mounting the front compartment 20 and the rear compartment 30 at the two ends of the energy compartment 10 in the direction of vehicle travel.

[0068] Assembly position 313 can be a workstation for parking transport device 1. By setting assembly position 313 in assembly device 3, transport device 1 can carry energy chamber 10 and park it in assembly position 313, so that transport device 1 can transport energy chamber 10 to assembly device 3, and facilitate the installation of front chamber 20 and rear chamber 30 at both ends of energy chamber 10 respectively.

[0069] In the above scheme, since the transport device 1 in the chassis production system can carry the energy chamber 10 and transfer the energy chamber 10 to the assembly position 313 of the assembly device 3 so as to install the front chamber 20 and the rear chamber 30, the repeated lifting of the energy chamber 10 from the transport line during the chassis production process is reduced, the transfer time is reduced, and the production efficiency of the chassis is improved.

[0070] In some embodiments, the assembly device 3 includes a base 31, a moving part 32, and a drive mechanism 33. The base 31 forms an assembly position 313, the moving part 32 is movably connected to the base 31, and the drive mechanism 33 is drively connected to the moving part 32 to drive the moving part 32 to move.

[0071] The base 31 can be the main structure of the assembly device 3, which is used to install and support other components in the assembly device 3. The base 31 can be installed on the ground so that the weight of other components in the assembly device 3 and the load borne by the assembly device 3 can be transferred to the ground through the base 31.

[0072] The movable component 32 may be a component movably connected to the base 31 in the assembly device 3. By being movably connected to the base 31, the movable component 32 can act on the energy chamber 10 by moving relative to the base 31.

[0073] For example, the movable connection between the movable component 32 and the base 31 can be such that the movable component 32 is slidably connected to the base 31, so that the movable component 32 can move relative to the base 31 in the horizontal direction and also move relative to the base 31 in the vertical direction Z.

[0074] The drive mechanism 33 can be a mechanism for providing driving power for the movement of the moving part 32. By driving the drive mechanism 33 to the moving part 32, the moving part 32 can act on the energy chamber 10 under the drive of the drive mechanism 33, so as to install the front chamber 20 and the rear chamber 30 on the energy chamber 10.

[0075] For example, the drive mechanism 33 may include a drive cylinder that can provide a driving force to the moving part 32 so that the moving part 32 moves relative to the base 31.

[0076] In some embodiments, the substrate 31 includes a first portion 311 and a second portion 312 disposed opposite to each other along a first direction X, an assembly position 313 is formed between the first portion 311 and the second portion 312, and the assembly position 313 has an inlet / outlet 3131 at at least one end in a second direction Y, the second direction Y intersecting the first direction X.

[0077] The first part 311 and the second part 312 can be two different parts of the base 31. The first part 311 and the second part are arranged at a relative interval along the first direction X, such that an assembly position 313 for parking the transport device 1 is formed between the first part 311 and the second part, so that the transport device 1 can transport the energy chamber 10 to the assembly device 3 by entering the assembly position 313.

[0078] The inlet / outlet 3131 can be an opening on the assembly position 313 for entering and exiting the transport device 1. It can connect the assembly position 313 with the outside world, so that the transport device 1 carrying the energy chamber 10 can enter the assembly position 313 through the inlet / outlet 3131, and also so that the transport device 1 carrying the assembled chassis can leave the assembly position 313 through the inlet / outlet 3131.

[0079] The second direction Y intersects with the first direction X, which can mean that the second direction Y is perpendicular to the first direction X. By setting the inlet / outlet 3131 at one end of the assembly position 313 in the second direction Y, the transport device 1 can quickly leave the assembly position 313 between the first part 311 and the second part from the inlet / outlet 3131.

[0080] For example, the assembly position 313 has inlets and outlets 3131 at both ends in the second direction Y, so that the transport device 1 can enter the assembly position 313 from the inlet and outlet 3131 at one end and leave the assembly position 313 from the inlet and outlet 3131 at the other end, making it convenient for the transport device 1 to enter and leave the assembly position 313.

[0081] In some embodiments, the drive mechanism 33 includes a translation component 331 and a lifting component 332. The translation component 331 is tractively connected to the moving component 32 and can drive the moving component 32 to clamp or disengage the energy chamber 10. The lifting component 332 is tractively connected to the moving component 32 and can drive the moving component 32 to rise and fall.

[0082] The translation component 331 can be a component used to drive the moving part 32 to move in the horizontal direction (first direction X and / or second direction Y). By driving the translation component 331 to the moving part 32, the translation component 331 can drive the moving part 32 to move in the horizontal direction, so that the moving part 32 can clamp or disengage from the energy chamber 10.

[0083] The lifting assembly 332 can be a component used to drive the moving part 32 to move up and down in the vertical direction Z. By connecting the lifting assembly 332 to the moving part 32, the lifting assembly 332 can drive the moving part 32 to move in the vertical direction Z, so that the moving part 32 can drive the energy chamber 10 to move up and down.

[0084] For example, there are two moving parts 32, two translation components 331, and two lifting components 332. The two moving parts 32 are slidably connected to the first part 311 and the second part 312, respectively. The two translation components 331 are driven to the two moving parts 32, respectively. The two lifting components 332 are driven to the two moving parts 32, respectively. This allows the two moving parts 32 to move closer to each other along the first direction X under the drive of the two translation components 331 and clamp the energy chamber 10. It also allows the two moving parts 32 to move further away from each other along the first direction X under the drive of the two translation components 331 and disengage from clamping the energy chamber 10. Furthermore, it allows the two moving parts 32 to lift the energy chamber 10 along the vertical direction Z under the drive of the two lifting components 332.

[0085] In some embodiments, the assembly device 3 includes a front compartment 20 positioning structure 34 and a rear compartment 30 positioning structure 35. The front compartment 20 positioning structure 34 is used to position the front compartment 20 in the energy compartment 10, and the rear compartment 30 positioning structure 35 is used to position the rear compartment 30 in the energy compartment 10.

[0086] The front compartment 20 positioning structure 34 can be used to position the front compartment 20 relative to the energy compartment 10. Through the front compartment 20 positioning structure 34, after the transfer device transfers the front compartment 20 to the end of the energy compartment 10, the front compartment 20 can be positioned more accurately in the energy compartment 10, so that the front compartment 20 and the energy compartment 10 are relatively positioned, reducing the possibility of the front compartment 20 moving relative to the energy compartment 10, and facilitating the subsequent connection and fixation of the front compartment 20 on the energy compartment 10.

[0087] For example, the positioning structure 34 of the front compartment 20 may include a positioning pin. The front compartment 20 is provided with a first positioning hole, and the energy compartment 10 is provided with a second positioning hole corresponding to the first positioning hole. The positioning pin passes through the first positioning hole and the second positioning hole, so that the front compartment 20 and the energy compartment 10 can be positioned relative to each other.

[0088] The rear compartment 30 positioning structure 35 can be used to position the rear compartment 30 relative to the energy compartment 10. Through the rear compartment 30 positioning structure 35, after the transfer device transfers the rear compartment 30 to the end of the energy compartment 10, the rear compartment 30 can be positioned more accurately in the energy compartment 10, so that the rear compartment 30 and the energy compartment 10 are relatively positioned, reducing the possibility of the rear compartment 30 moving relative to the energy compartment 10, and facilitating the subsequent connection and fixation of the rear compartment 30 on the energy compartment 10.

[0089] For example, the positioning structure 35 of the rear compartment 30 may include a positioning pin. The rear compartment 30 is provided with a third positioning hole, and the energy compartment 10 is provided with a fourth positioning hole corresponding to the third positioning hole. The positioning pin passes through the third positioning hole and the fourth positioning hole, so that the rear compartment 30 and the energy compartment 10 can be positioned relative to each other.

[0090] In some embodiments, the moving part 32 is provided with a front compartment 20 clamping mechanism 36, a rear compartment 30 clamping mechanism 37, and an energy compartment 10 clamping mechanism 38. The front compartment 20 clamping mechanism 36 is used to clamp the front compartment 20, the rear compartment 30 clamping mechanism 37 is used to clamp the rear compartment 30, and the energy compartment 10 clamping mechanism 38 is used to clamp the energy compartment 10.

[0091] The front compartment 20 clamping mechanism 36 can be used to clamp and fix the front compartment 20. By clamping the front compartment 20, it can reduce the possibility of the front compartment 20 moving during installation, which helps to improve the installation accuracy of the front compartment 20. Through the front compartment 20 clamping mechanism 36, after the transfer device positions the front compartment 20 at the end of the energy compartment 10, the position of the front compartment 20 can be kept relatively stable.

[0092] For example, the clamping mechanism 36 of the front compartment 20 may include a support such as a gripper, which can hold the front compartment 20 in position by clamping it.

[0093] The rear compartment 30 clamping mechanism 37 is a mechanism for clamping and fixing the rear compartment 30. By clamping the rear compartment 30, it can reduce the possibility of movement of the rear compartment 30 during installation, which helps to improve the installation accuracy of the rear compartment 30. Through the rear compartment 30 clamping mechanism 37, after the transfer device positions the rear compartment 30 at the end of the energy chamber 10, the position of the rear compartment 30 can be kept relatively stable.

[0094] For example, the clamping mechanism 37 of the rear compartment 30 may include a support such as a gripper, which can hold the rear compartment 30 in position by clamping it.

[0095] The energy chamber 10 clamping mechanism 38 can be used to clamp and fix the energy chamber 10. By clamping the energy chamber 10, it can reduce the possibility of movement of the energy chamber 10 during installation, which helps to improve the installation accuracy of the entire chassis. With the energy chamber 10 clamping mechanism 38, after the transfer device positions the energy chamber 10 at its end, the position of the energy chamber 10 can be kept relatively stable.

[0096] For example, the energy chamber 10 clamping mechanism 38 may include a support such as a gripper, which can hold the energy chamber 10 in position by clamping it.

[0097] In some embodiments, reference Figure 2 The transport device 1 includes a vehicle body 11 and a pallet 12. The pallet 12 is movably mounted on the top of the vehicle body 11 and is used to carry the energy chamber 10.

[0098] The vehicle body 11 and the pallet 12 are two parts of the transport device 1, with the pallet 12 being the component used to carry the energy chamber 10. By placing the pallet 12 on the top of the vehicle body 11, the vehicle body 11 can carry the energy chamber 10 via the pallet 12 on its top, making the transport of the energy chamber 10 more convenient.

[0099] The tray 12 is movably disposed on the top of the vehicle body 11, which means that the tray 12 can move horizontally on the top of the vehicle body 11, so that after the moving part 32 clamps the energy chamber 10 on the tray 12, it can adjust the horizontal position of the energy chamber 10 by moving horizontally.

[0100] For example, the tray 12 is movably disposed on the top of the vehicle body 11. The top of the vehicle body 11 may have a sliding hole, and the tray 12 may have a slide block. The inner diameter of the sliding hole is larger than that of the slide block, and the slide block is slidably disposed in the sliding hole, so that the tray 12 is movably disposed on the vehicle body 11.

[0101] In some embodiments, the transport device 1 includes a locking mechanism capable of locking or unlocking the pallet 12.

[0102] The locking mechanism can be a mechanism that can lock the pallet 12 to the vehicle body 11, which can reduce the relative displacement between the pallet 12 and the vehicle body 11, thereby reducing the risk of the energy storage 10 shaking during transportation.

[0103] By configuring the locking mechanism to both lock and unlock the tray 12, the locking mechanism can both lock the tray 12 on the vehicle body 11 and allow the tray 12 to move relative to the vehicle body 11.

[0104] For example, the locking mechanism may include a pin, a first socket provided on the top of the vehicle body 11 and a second socket provided on the tray 12, and the pin locks the tray 12 on the vehicle body 11 by engaging with the first socket and the second socket.

[0105] Some embodiments of this application also provide a method for manufacturing a chassis, see reference. Figure 3 The manufacturing method of this chassis includes the following steps:

[0106] S1. The energy storage chamber 10 is fed into the transport device 1, which transports the energy storage chamber 10 to the assembly position 313.

[0107] The energy storage 10 can be the energy storage 10 described in the aforementioned technical solution, and the transport device 1 can be the transport device 1 described in the aforementioned chassis production system. In step S1 above, the energy storage 10 is directly transported to the assembly position 313 by the transport device 1, which can reduce the hoisting and transfer process of the energy storage 10, save transfer time, and help improve the production efficiency of the chassis.

[0108] S2. Transfer the front compartment 20 and the rear compartment 30 to the two ends of the energy compartment 10 respectively.

[0109] The front compartment 20 and the rear compartment 30 can be the front compartment 20 and the rear compartment 30 described in the aforementioned technical solution. In step S2 above, by transferring the front compartment 20 and the rear compartment 30 to the two ends of the energy compartment 10 respectively, the front compartment 20 and the rear compartment 30 can be brought close to the energy compartment 10, which facilitates the subsequent fixed connection of the front compartment 20 and the rear compartment 30 to the energy compartment 10.

[0110] For example, the front compartment 20 and the rear compartment 30 can be transferred from the conveyor line to both ends of the energy compartment 10 by means of hoisting equipment, forklifts or other devices.

[0111] S3. Connect the front compartment 20 and the rear compartment 30 to the two ends of the energy compartment 10 respectively.

[0112] In step S3 above, the front compartment 20 and the rear compartment 30 can be connected to the two ends of the energy compartment 10 in the direction of vehicle travel using connecting pins, connecting bolts, or other connecting parts, making the connection between the front compartment 20 and the rear compartment 30 on the energy compartment 10 convenient; or the front compartment 20 and the rear compartment 30 can be connected to the two ends of the energy compartment 10 in the direction of vehicle travel using welding, gluing, or other processes, making the connection between the front compartment 20 and the rear compartment 30 on the energy compartment 10 more secure.

[0113] Through the above step S3, the front compartment 20 and the rear compartment 30 are connected to the energy compartment 10 to form the chassis of the electric vehicle.

[0114] S4. The transport device 1 carries the energy storage 10 and transfers the energy storage 10, the front storage 20 and the rear storage 30 to the next work station.

[0115] In step S4 above, refer to Figure 4 The transport device 1, through the carrying energy chamber 10, can carry the assembled energy chamber 10, front chamber 20 and rear chamber 30, and can transport the assembled energy chamber 10, front chamber 20 and rear chamber 30 to the work station of the next process so that the operation can continue.

[0116] In the above scheme, since the transport device 1 in the chassis production method can carry the energy chamber 10 and transfer the energy chamber 10 to the assembly position 313 for the installation of the front chamber 20 and the rear chamber 30, the repeated lifting of the energy chamber 10 from the transport line during the chassis production process is reduced, the transfer time is reduced, and the production efficiency of the chassis is improved.

[0117] In some embodiments, prior to step S2, refer to Figure 5 The chassis manufacturing method also includes the following steps:

[0118] S11, Fixed Energy Chamber 10.

[0119] By fixing the energy chamber 10 before transferring the front chamber 20 and the rear chamber 30 to the two ends of the energy chamber 10, as described in step S11, the possibility of the energy chamber 10 shifting due to bumps during the transfer of the front chamber 20 and the rear chamber 30 can be reduced, which is beneficial to improving the assembly accuracy of the energy chamber 10, the front chamber 20 and the rear chamber 30.

[0120] In some embodiments, reference Figure 6 Step S11 includes the following steps:

[0121] S111. Adjust the horizontal position of the energy chamber 10 so that the energy chamber 10 is within the first preset position range.

[0122] In step S111 above, adjusting the horizontal position of the energy chamber 10 can refer to positioning the energy chamber 10 horizontally. By adjusting the horizontal position of the energy chamber 10 to within the first preset position range, the position of the energy chamber 10 becomes more controllable, which helps improve the accuracy of subsequent assembly of the front chamber 20, the rear chamber 30, and the energy chamber 10.

[0123] S112. Raise the energy chamber 10 to the preset height.

[0124] In step S112 above, by lifting the energy chamber 10 to a preset height, the energy chamber 10 is placed at a suitable height, which can provide suitable space for the installation of the front chamber 20 and the rear chamber 30, and facilitate the subsequent connection of the front chamber 20 and the rear chamber 30 on the energy chamber 10.

[0125] S113. Adjust the horizontal position of the energy chamber 10 so that the energy chamber 10 is within a second preset position range, which is smaller than the first preset position range.

[0126] In step S113 above, adjusting the horizontal position of the energy chamber 10 can refer to performing a secondary positioning of the energy chamber 10 in the horizontal position. By adjusting the horizontal position of the energy chamber 10 to within the second preset position range, the position of the energy chamber 10 becomes more controllable, which is beneficial to further improve the accuracy of the subsequent assembly of the front chamber 20, the rear chamber 30, and the energy chamber 10.

[0127] The second preset position range being smaller than the first preset position range can mean that, in the vertical direction Z, the projection range of the second preset position is smaller than the projection range of the first preset position, making the positioning of the energy chamber 10 more accurate after it is within the second preset position range, which is beneficial to improving the positioning accuracy of the energy chamber 10.

[0128] S114, Clamping Energy Chamber 10.

[0129] In step S114 above, the position of the energy chamber 10 is fixed by clamping it after two position adjustments, so that the energy chamber 10 is less likely to move during the subsequent chassis assembly process.

[0130] In the above steps, the energy chamber 10 is positioned more accurately by performing a first positioning and a second positioning in sequence.

[0131] In some embodiments, step S3 includes the following steps:

[0132] S31, fixed front compartment 20 and rear compartment 30.

[0133] In step S31 above, by fixing the front compartment 20 and the rear compartment 30, the front compartment 20 and the rear compartment 30 are less likely to move during the subsequent process of connecting the front compartment 20 and the rear compartment 30 to the energy compartment 10, which helps to improve the accuracy of the connection position of the front compartment 20 and the rear compartment 30 on the energy compartment 10.

[0134] S32. Connect the front compartment 20 and the rear compartment 30 to the two ends of the energy compartment 10 respectively.

[0135] In step S32 above, the front compartment 20 and the rear compartment 30 are respectively connected to the two ends of the energy compartment 10. This can be done by using connecting bolts to connect the front compartment 20 and the rear compartment 30 to the two ends of the energy compartment 10 in the direction of vehicle travel, so that the front compartment 20 and the rear compartment 30 are connected to the energy compartment 10 to form a whole.

[0136] In some embodiments, reference Figure 7 Step S31 includes the following steps:

[0137] S311, Position the front warehouse 20 to the energy warehouse 10.

[0138] In step S311 above, by positioning the front compartment 20 on the energy compartment 10, the relative position between the front compartment 20 and the energy compartment 10 is more accurate, which is beneficial to improving the connection quality of the front compartment 20 on the energy compartment 10.

[0139] S312, Position the rear compartment 30 to the energy compartment 10;

[0140] In step S312 above, by positioning the rear compartment 30 on the energy compartment 10, the relative position between the rear compartment 30 and the energy compartment 10 is more accurate, which is beneficial to improving the connection quality of the rear compartment 30 on the energy compartment 10.

[0141] S313, clamping front compartment 20.

[0142] In step S312 above, by clamping the front compartment 20, the position of the front compartment 20 is kept relatively stable and it is not easy for it to move relative to the energy compartment 10, which is conducive to improving the connection quality of the front compartment 20 to the energy compartment 10.

[0143] S314, clamping rear compartment 30.

[0144] In step S314 above, by clamping the rear compartment 30, the position of the rear compartment 30 is kept relatively stable and it is not easy for it to move relative to the energy compartment 10, which is conducive to improving the connection quality of the rear compartment 30 to the energy compartment 10.

[0145] In some embodiments, continue to refer to Figure 5 Prior to step S2, the chassis manufacturing method further includes the following steps:

[0146] S12. Test the battery in the energy chamber 10.

[0147] In step S12 above, the batteries in the energy chamber 10 are tested before the front chamber 20 and the rear chamber 30 are transferred to the two ends of the energy chamber 10 respectively. This makes the space in the energy chamber 10 larger when testing the batteries, and the monitoring equipment is less likely to interfere with the front chamber 20 and the rear chamber 30, which helps to improve the convenience of testing.

[0148] In some embodiments, prior to step S2, the chassis manufacturing method further includes the following steps:

[0149] S13. Install a seal on the energy chamber 10.

[0150] In step S13 above, by setting a seal on the combined overlapping surface of the energy chamber 10 before transferring the front chamber 20 and the rear chamber 30 to the two ends of the energy chamber 10 respectively, the space where the energy chamber 10 is located is larger when setting the seal, which is conducive to improving the convenience of setting the seal.

[0151] For example, the seal can be foam. Foam is placed on the combined overlapping surface of the energy chamber 10 with the front chamber 20 and the rear chamber 30, which helps to improve the sealing between the energy chamber 10 and the front chamber 20 and the rear chamber 30.
