Description

Technical Field

[0001] This invention relates to the field of vehicle body assembly technology, specifically a modular vehicle body assembly structure for new energy vehicles. Background Technology

[0002] The assembly of a new energy vehicle body includes the connection and assembly of the body frame, chassis, and battery pack. In traditional new energy vehicle designs, the battery pack and body mostly adopt a separate structure. That is, the battery pack is an independent, closed assembly component, suspended or fixed under the vehicle floor by bolts, fasteners, and other connection methods. This "underbody load-bearing" structure has become the mainstream technical solution in the early stages of the industry.

[0003] However, most existing battery packs are fixed to the vehicle body using a single bolt or snap-fit ​​method, making the connection process complex and hindering rapid assembly. Furthermore, current battery pack connection methods rely solely on built-in silicone pads for shock absorption. However, vehicles experience continuous high-frequency slight vibrations and occasional low-frequency large vibrations from bumpy roads, speed bumps, and gravel roads, as well as vibrations generated by the drive motor during operation and energy recovery. Vehicle acceleration, braking, and turning expose the battery pack to longitudinal and lateral inertial forces, and in extreme cases, even massive impacts. These forces are directly transmitted to the battery pack, and the magnitude of the vibration varies under different conditions. A single silicone pad is insufficient for adequate cushioning. Summary of the Invention

[0004] The purpose of this invention is to provide a modular body assembly structure for new energy vehicles to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a modular body splicing structure for new energy vehicles, including a car battery pack, a body fixing plate is provided on the upper side of the car battery pack, a uniformly distributed fixing nail is fixedly connected to the lower side of the body fixing plate, and a uniformly distributed splicing component is fixedly connected to the outer side of the car battery pack, wherein the splicing component and the fixing nail are installed by quick-connect fittings.

[0006] The quick-connect component includes an installation component, a linkage component, a pushing component, a guide component, a control component, and a locking plate. The upper side of the splicing component is fixedly connected to the guide component, and two sets of installation components are symmetrically installed on the outer side of the guide component. The upper side of the guide component is fixedly installed with the linkage component, and the installation component is threadedly connected to the pushing component.

[0007] The guide assembly includes a base plate and guide members. The base plate is fixedly connected to the upper side of the splicing member, and two sets of symmetrically arranged guide members are fixedly connected to the upper side of the base plate.

[0008] The guide and linkage components are all fixedly installed with control components, and the control components are fixedly installed with locking plates, which are engaged with fixing nails.

[0009] Furthermore, the splicing component includes a splicing base and a splicing connector. The outer side of the automotive battery pack is fixedly connected with evenly distributed splicing bases, and the inner side of the splicing base is snapped with a splicing connector.

[0010] Align the splice joint with the splice base, and insert the splice joint into the inside of the splice base.

[0011] Furthermore, the guide component includes a sliding plate, a fixed guide rail, a sliding block, a support plate, and a cover plate. The splice joint is fixedly connected to the base plate. Two sets of symmetrically arranged fixed guide rails are fixedly connected to the upper side of the base plate. A sliding block is slidably connected to the outer side of the fixed guide rail. A sliding plate is fixedly connected to the upper side of the sliding block. A support plate is fixedly connected to the upper side of the sliding plate. Two sets of symmetrically arranged cover plates are fixedly connected to the upper side of the base plate.

[0012] Furthermore, the mounting assembly includes a support plate, a first bevel gear, a second bevel gear, a fixing plate, a track plate, and a threaded rod. Two sets of track plates are fixedly connected to the outer side of the base plate. A fixing plate is fixedly connected to the side of the track plate away from the base plate. A support plate is fixedly connected to the side of the fixing plate away from the track plate. The first bevel gear and the second bevel gear are rotatably connected to the inner side of the support plate. The first bevel gear and the second bevel gear mesh with each other. A screw head is fixedly connected to the lower side of the first bevel gear. A threaded rod is fixedly connected to the other end of the second bevel gear. The threaded rod passes through the support plate and the fixing plate.

[0013] Furthermore, the pushing assembly includes a first pushing plate and a second pushing plate. The first pushing plate is threadedly connected to the outer side of one set of threaded rods, and the second pushing plate slides inside the set of track plates. The second pushing plate is threadedly connected to the outer side of another set of threaded rods, and the second pushing plate slides inside the other set of track plates.

[0014] Furthermore, the linkage assembly includes a lower mounting base, a first movable plate, a second movable plate, a first push rod, a cylindrical rod, a connecting block, a second push rod, a pressure block, an upper mounting base, and a first spring. The lower mounting base is fixedly connected to the upper side of the middle part of the base plate. The first push rod is slidably connected to the inner side of the lower mounting base. A cylindrical rod is fixedly connected to the inner side of the first push rod. A connecting block is fixedly connected to the upper side of the first push rod. The first movable plate and the second movable plate are slidably connected to the inner side of the lower mounting base. The second push rod is fixedly connected to the upper side of the connecting block. The upper mounting base is fixedly connected to the upper side of the lower mounting base. A pressure block is fixedly connected to the second push rod. A first spring is sleeved on one end of the pressure block and inside the upper mounting base. Both ends of the upper and lower mounting bases are fixedly connected to corresponding cover plates. The second push rod slides inside the upper mounting base.

[0015] Furthermore, the movable plate one and movable plate two are provided with sliding grooves, the support plate slides in the sliding grooves, the inner side of the lower mounting base is provided with through grooves corresponding to movable plate one, movable plate two and push rod one, and the inner side of the upper mounting base is provided with through holes corresponding to pressure block and spring one.

[0016] Furthermore, the first movable plate and the second movable plate are respectively fixedly connected to their corresponding movable plates.

[0017] The first bevel gear rotates, and the first bevel gear meshes with and drives the second bevel gear to rotate. The second bevel gear drives the threaded rod fixedly connected to it to rotate synchronously, which in turn drives the corresponding push plate one to move along the track plate to the bottom plate side, thereby pushing the push rod one and the push rod two.

[0018] During the movement of push rod one and push rod two, push rod one, through the action of the cylindrical rod and the guiding action of the sliding grooves on the moving plate one and moving plate two, drives the moving plate one and moving plate two to move outward, thereby simultaneously driving the moving plate, support plate, and sliding block to slide outward along the fixed guide rail. At the same time, push rod two slides outward, so that the adjustment components and clamping plate on the support plate and push rod two move outward synchronously, ensuring that the clamping plate and the fixing nail on the vehicle body fixing plate are in a state where they cannot make contact.

[0019] Furthermore, the control assembly includes a fixed housing, a rotating shaft, a bearing, a gear, a rack, a moving rod, a cylindrical housing, a partition, a second spring, a magnetic block, and a coil. The upper side of the second push rod and the support plate are both fixedly connected to the fixed housing. The inner side of the fixed housing is equipped with a bearing, and the inner side of the bearing is rotatably connected to the rotating shaft. The upper part of the rotating shaft is equipped with a gear.

[0020] After the splicing joint and splicing seat are inserted into place, the electric screwdriver on the AGV (Automated Guided Vehicle) drives the push plate one to reset. At this time, push rod one and push rod two are reset under the spring force of spring one. At the same time, the clamping plate and the fixing nail are engaged. Then, the electric screwdriver engages with the screw head on another set of bevel gears one, and drives the corresponding threaded rod to rotate, thereby driving push plate two to move towards the bottom plate side, and then pushing push plate two to fit against push rod one and push rod two, realizing the limiting of push rod one and push rod two. At this time, the car battery pack has completed the splicing operation with the car body.

[0021] Each splicing point is equipped with a three-point interlocking mechanism, ensuring a secure connection.

[0022] A rack meshes with the outer side of the gear. Two sets of cylindrical shells are fixedly connected to the outer side of the fixed shell. A partition is fixedly connected to the inner side of the cylindrical shell. A moving rod is slidably connected to the inner side of the cylindrical shell. The moving rod passes through the partition. A second spring is sleeved on the outer side of the moving rod. The second spring is disposed between the moving rod and the partition. A magnetic block is fixedly connected to the end of the moving rod away from the fixed shell. A coil is fixedly connected to the inner side of the cylindrical shell.

[0023] The inner side of the fixed housing is provided with mounting grooves corresponding to the gears and racks.

[0024] Furthermore, the rotating shaft is fixedly connected to the clamping plate, the clamping plate has a rectangular groove corresponding to the fixing nail, the second push plate corresponds to the end of the second push rod and the first push rod away from the pressure block, the first push plate corresponds to the end of the second push rod and the first push rod close to the pressure block, and the cover plate has a through groove corresponding to the second push rod and the first push rod.

[0025] By detecting the magnitude of the vibration force, the external vehicle system controls the flow of a corresponding current into the coil. This causes the coil to generate a magnetic field that repels the separator. The vibration force causes the clamp to rotate while simultaneously sliding relative to the fixing pin. As the clamp rotates, it drives the gears and shafts fixed to it to rotate synchronously. This causes the gears to mesh and drive the rack to slide back and forth. Because the coil generates a magnetic field that repels the magnetic block, the resistance to the clamp's rotation can be controlled by adjusting the change in the magnetic field. The greater the vibration force on the car battery pack, the greater the current flowing into the coil, and the greater the resistance to the clamp's rotation. This allows for automated control of the cushioning and shock absorption of the car battery pack based on the vehicle's driving conditions.

[0026] Compared with the prior art, the present invention provides a modular body splicing structure for new energy vehicles, which has the following beneficial effects:

[0027] 1. This new energy vehicle uses a modular body splicing structure. Through the cooperation of splicing components, installation components, linkage components, pushing components, guiding components, clamping plates, and control components, it achieves the goal of rapid modular splicing of the body. Moreover, each splicing point is equipped with a three-point clamping, which makes the splicing firm and achieves the effect of rapid splicing and disassembly. This improves the current situation where most battery packs are fixed to the body with a single bolt or a single clamping method, which makes the operation of connecting them to the body more complicated and unable to achieve rapid splicing.

[0028] 2. This new energy vehicle uses a modular body splicing structure. Through the function of the control components, it can automatically adjust the corresponding shock absorption resistance according to different road conditions or different operating states of the vehicle. This results in greater vibration force on the car battery pack, greater current flowing into the coil, and greater resistance to the rotation of the clamping plate. In this way, it can automatically control the shock absorption force on the car battery pack according to the vehicle's driving state, thus providing better protection for the car battery pack.

[0051] Furthermore, the mounting assembly 5 includes a support plate 51, a first bevel gear 52, a second bevel gear 53, a fixing plate 54, a track plate 55, and a threaded rod 56. Two sets of track plates 55 are fixedly connected to the outer side of the base plate 81. A fixing plate 54 is fixedly connected to the side of the track plate 55 away from the base plate 81. A support plate 51 is fixedly connected to the side of the fixing plate 54 away from the track plate 55. The first bevel gear 52 and the second bevel gear 53 are rotatably connected to the inner side of the support plate 51. The first bevel gear 52 and the second bevel gear 53 mesh with each other. A screw head is fixedly connected to the lower side of the first bevel gear 52. A threaded rod 56 is fixedly connected to the other end of the second bevel gear 53. The threaded rod 56 passes through the support plate 51 and the fixing plate 54.

[0052] Furthermore, the pushing assembly 7 includes a first pushing plate 71 and a second pushing plate 72.

The second pushing plate 72 is threadedly connected to the outer side of another set of threaded rods 56, and the second pushing plate 72 slides on the inner side of another set of track plates 55.

[0053] Furthermore, the linkage component 6 includes a lower mounting base 61, a first movable plate 62, a second movable plate 63, a first push rod 64, a cylindrical rod 65, a connecting block 66, a second push rod 67, a pressure block 68, an upper mounting base 69, and a first spring 610.

The inner side of the mounting base 61 is slidably connected to a movable plate 62 and a movable plate 63. The upper side of the connecting block 66 is fixedly connected to a push rod 67. The upper side of the lower mounting base 61 is fixedly connected to an upper mounting base 69. A pressure block 68 is fixedly connected to the push rod 67. A spring 610 is sleeved on one end of the pressure block 68 and inside the upper mounting base 69. The two ends of the upper mounting base 69 and the lower mounting base 61 are respectively fixedly connected to the corresponding cover plates 86. The push rod 67 slides inside the upper mounting base 69.

[0054] Furthermore, sliding grooves are provided on the first movable plate 62 and the second movable plate 63, and the support plate 85 slides in the sliding grooves. The inner side of the lower mounting base 61 is provided with through grooves corresponding to the first movable plate 62, the second movable plate 63, and the first push rod 64. The inner side of the upper mounting base 69 is provided with through holes corresponding to the pressure block 68 and the first spring 610.

[0055] Furthermore, movable plate 1 62 and movable plate 2 63 are respectively fixedly connected to the corresponding movable plate 82.

[0056] The first bevel gear 52 rotates, and the first bevel gear 52 meshes with and drives the second bevel gear 53 to rotate. The second bevel gear 53 drives the threaded rod 56, which is fixedly connected to it, to rotate synchronously. This drives the corresponding push plate 71 to move along the track plate 55 towards the bottom plate 81, and then pushes the first push rod 64 and the second push rod 67.

[0057] During the movement of push rod 64 and push rod 67, push rod 64, through the action of cylindrical rod 65 and the guiding action of sliding grooves on moving plate 62 and moving plate 63, drives moving plate 62 and moving plate 63 to move outward, thereby simultaneously driving moving plate 82, support plate 85, and sliding block 84 to slide outward along fixed guide rail 83. At the same time, push rod 67 slides outward, so that the adjustment component 9 on support plate 85 and push rod 67 and the clamping plate 10 move outward synchronously, ensuring that the clamping plate 10 and the fixing nail 3 on the vehicle body fixing plate 2 are in a state where they cannot make contact.

[0058] Furthermore, the control component 9 includes a fixed housing 91, a rotating shaft 92, a bearing 93, a gear 94, a rack 95, a moving rod 96, a cylindrical housing 97, a partition 98, a second spring 99, a magnetic block 910, and a coil 911. The upper side of the second push rod 67 and the support plate 85 are all fixedly connected to the fixed housing 91. The bearing 93 is installed inside the fixed housing 91. The rotating shaft 92 is rotatably connected inside the bearing 93. The gear 94 is installed on the upper part of the rotating shaft 92.

[0059] After the splicing joint 42 and the splicing base 41 are inserted into place, the electric screwdriver on the AGV (Automated Guided Vehicle) drives the push plate 71 to reset. At this time, the push rod 64 and the second push rod 67 are reset under the spring force of the spring 610. At the same time, the clamping plate 10 is engaged with the fixing nail 3. Then, the electric screwdriver engages with the screw head on another set of bevel gears 52, and drives the corresponding threaded rod 56 to rotate, thereby driving the push plate 72 to move towards the base plate 81. This pushes the push plate 72 to fit against the push rods 64 and 67, thus limiting the movement of the push rods 64 and 67. At this point, the car battery pack 1 has completed the splicing operation with the car body.

[0060] Each splicing point is equipped with a three-point interlocking mechanism, ensuring a secure connection.

[0061] A rack 95 meshes with the outer side of the gear 94. Two sets of cylindrical shells 97 are fixedly connected to the outer side of the fixed shell 91. A partition 98 is fixedly connected to the inner side of the cylindrical shell 97. A moving rod 96 is slidably connected to the inner side of the cylindrical shell 97. The moving rod 96 passes through the partition 98. A second spring 99 is sleeved on the outer side of the moving rod 96. The second spring 99 is located between the moving rod 96 and the partition 98. A magnetic block 910 is fixedly connected to the end of the moving rod 96 away from the fixed shell 91. A coil 911 is fixedly connected to the inner side of the cylindrical shell 97.

[0062] The inner side of the fixed housing 91 is provided with mounting grooves corresponding to the gear 94 and the rack 95.

[0063] Furthermore, the rotating shaft 92 is fixedly connected to the clamping plate 10. The clamping plate 10 has a rectangular groove corresponding to the fixing nail 3. The push plate 72 corresponds to the end of the push rod 67 and the push rod 64 away from the pressure block 68. The push plate 71 corresponds to the end of the push rod 67 and the push rod 64 close to the pressure block 68. The cover plate 86 has a through groove corresponding to the push rod 67 and the push rod 64.

[0064] Based on the detected vibration force, the external vehicle system controls the flow of a corresponding current into the coil 911. This causes the coil 911 to generate a magnetic field that repels the separator 98. The vibration force causes the clamping plate 10 to rotate while simultaneously sliding relative to the fixing pin 3. As the clamping plate 10 rotates, it drives the gear 94 and the rotating shaft 92, which are fixedly connected to it, to rotate synchronously. This causes the gear 94 to mesh and drive the rack 95 to slide back and forth. Since the coil 911 generates a magnetic field that repels the magnetic block 910, the resistance to the rotation of the clamping plate 10 can be controlled by adjusting the change in the magnetic field force. The greater the vibration force on the car battery pack 1, the greater the current flowing into the coil 911, and the greater the resistance to the rotation of the clamping plate 10. This allows for automated control of the damping and shock absorption force on the car battery pack 1 based on the vehicle's driving conditions.

[0065] The specific usage and function of this embodiment.

[0066] The vehicle body fixing plate 2 is fixedly installed on the vehicle body. When it is necessary to splice the car battery pack 1 to the vehicle body, the car battery pack 1 is carried by an external AGV automatic guided transport vehicle. Then, according to the preset path, the car battery pack 1 is accurately transported to the bottom of the vehicle to be assembled. Then, the lifting device on the AGV automatic guided transport vehicle is activated to push the car battery pack 1 to be aligned with the vehicle body, so that the splicing joint 42 is aligned with the splicing seat 41. The splicing joint 42 is inserted into the inside of the splicing seat 41. Before this, the electric screwdriver on the AGV automatic guided transport vehicle is aligned with the screw head on the bevel gear 52 away from the pressure block 68. Then, the electric screwdriver is activated, which drives the bevel gear 52 to rotate. The bevel gear 52 meshes and drives the bevel gear 53 to rotate. The bevel gear 53 drives the threaded rod 56 fixedly connected to it to rotate synchronously, which in turn drives the corresponding push plate 71 to move along the track plate 55 to the bottom plate 81 side, which in turn pushes the push rod 64 and the push rod 67.

[0067] During the movement of push rod 64 and push rod 67, push rod 64, through the action of cylindrical rod 65 and the guiding action of sliding grooves on moving plate 62 and moving plate 63, drives moving plate 62 and moving plate 63 to move outward, thereby simultaneously driving moving plate 82, support plate 85, and sliding block 84 to slide outward along fixed guide rail 83. At the same time, push rod 67 slides outward, so that the adjustment component 9 on support plate 85 and push rod 67 and the clamping plate 10 move outward synchronously, ensuring that the clamping plate 10 and the fixing nail 3 on the vehicle body fixing plate 2 are in a state where they cannot make contact.

[0068] After the splicing joint 42 and the splicing base 41 are inserted into place, the electric screwdriver on the AGV (Automated Guided Vehicle) drives the push plate 71 to reset. At this time, the push rod 64 and the push rod 67 are reset under the spring force of the spring 610. At the same time, the clamping plate 10 is engaged with the fixing nail 3. Then, the electric screwdriver engages with the screw head on another set of bevel gears 52, and drives the corresponding threaded rod 56 to rotate. This causes the push plate 72 to move towards the base plate 81, thereby pushing the push plate 72 to fit against the push rods 64 and 67, thus limiting the movement of the push rods 64 and 67. At this point, the car battery pack 1 has completed the splicing operation with the car body.

[0069] Each splicing point is equipped with a three-point interlocking mechanism, ensuring a secure connection.

[0070] When it is necessary to disassemble the car battery pack 1 from the car body, the above operation is performed to move the clamp 10 outward, so that the clamp 10 is separated from the fixing nail 3, and then the splicing joint 42 is separated from the splicing seat 41 by its own gravity, thus achieving the purpose of quick splicing and quick disassembly.

[0071] While the vehicle is in motion, the external vehicle infotainment system can detect the vehicle's operating status via an acceleration sensor, such as when the vehicle is traveling on bumpy roads, speed bumps, or gravel roads, and the operating status of the drive motor. It can also detect vehicle acceleration, braking, and turning. Furthermore, it can detect the vibration force generated on the vehicle's battery pack 1 when the vehicle encounters extreme impacts.

[0072] Based on the detected vibration force, the external vehicle system controls the flow of a corresponding current into the coil 911. This causes the coil 911 to generate a magnetic field that repels the separator 98. The vibration force causes the clamping plate 10 to rotate while simultaneously sliding relative to the fixing pin 3. As the clamping plate 10 rotates, it drives the gear 94 and the rotating shaft 92, which are fixedly connected to it, to rotate synchronously. This causes the gear 94 to mesh and drive the rack 95 to slide back and forth. Since the coil 911 generates a magnetic field that repels the magnetic block 910, the resistance to the rotation of the clamping plate 10 can be controlled by adjusting the change in the magnetic field force. The greater the vibration force on the car battery pack 1, the greater the current flowing into the coil 911, and the greater the resistance to the rotation of the clamping plate 10. This allows for automated control of the damping and shock absorption force on the car battery pack 1 based on the vehicle's driving conditions.

[0073] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
