Description

Technical Field

[0001] The present application relates to the field of automobile manufacturing technology, and in particular to an electric vehicle transportation device. Background Art

[0002] Electric vehicles are vehicles that use an onboard power source as a power source and use an electric motor to drive the wheels. They mainly rely on rechargeable batteries to provide energy. Compared with traditional fuel vehicles, electric vehicles have significant environmental advantages. They produce no or very little exhaust emissions, and can effectively reduce air pollution and greenhouse gas emissions. They usually have high energy conversion efficiency and can directly convert electrical energy into mechanical energy to propel the vehicle forward. With technological advances, the range of electric vehicles continues to increase, and charging facilities are becoming increasingly complete. They are gradually becoming one of the important choices for modern transportation.

[0003] When electric vehicles are produced, almost all operations are performed by automated equipment and robots from the entry of raw materials to the final assembly. Through advanced sensor technology and control systems, each processing step is carried out accurately to ensure product quality and consistency. For example, body stamping, welding, painting and other links can be completed efficiently and accurately by robotic arms, and battery pack assembly and testing can also be carried out at specific automated workstations. The fully automatic production of electric vehicles is mainly carried out in the final assembly workshop. After production is completed, it needs to be transferred to the inspection workshop for comprehensive and detailed inspection by technicians to ensure that strict standards and safety performance requirements are met before leaving the factory.

[0004] In the prior art, the transfer of electric vehicles from the finished product area of ​​the general assembly workshop to the inspection area of ​​the inspection workshop mainly relies on the AGV automatic guided vehicle body.

Since the battery pack of the electric vehicle is mostly designed on the bottom side of the bottom plate, the lifting structure of the AGV automatic guided vehicle body will squeeze the battery pack, which is not only poor in practicality and safety, but also affects the life of the battery. In addition, when the AGV automatic guided vehicle body encounters a bumpy road, it will vibrate and transmit force to the electric vehicle, which not only affects the stability of the electric vehicle transportation, but may also cause potential damage to the electric vehicle and cause safety hazards.

[0016] An embodiment of the present invention provides an electric vehicle transportation device, which includes a first lifting mechanism and an AGV automatic guided vehicle. The first lifting mechanism includes two symmetrically arranged first lifting structures. The first lifting structure includes a mounting seat, a first lifting assembly and two first lifting assemblies. The first lifting assembly is arranged on the mounting seat. The two first lifting assemblies are both connected to the first lifting assembly so that the first lifting assembly can drive the first lifting assembly to move along the height direction of the mounting seat, and the two first lifting assemblies are arranged at intervals along the length direction of the mounting seat. The first lifting assembly is configured to lift the wheels of the electric vehicle. The width of the AGV automatic guided vehicle is less than the distance between the two first lifting structures. The AGV automatic guided vehicle includes an automatic guided vehicle body and a second lifting mechanism. The second lifting mechanism includes two second lifting structures, and the two second lifting structures are arranged at intervals along the length direction of the automatic guided vehicle body. The length direction of the automatic guided vehicle body is consistent with the length direction of the mounting seat. The second lifting structure includes a lifting plate, a second lifting assembly and two second lifting assemblies. The second lifting assembly is arranged on the automatic guided vehicle body. The lifting plate is connected to the second lifting assembly so that the second lifting assembly can drive the lifting plate to move along the height direction of the automatic guided vehicle body. The length direction of the lifting plate is perpendicular to the length direction of the automatic guided vehicle body. Two second lifting assemblies are symmetrically installed on the lifting plate along the length direction of the lifting plate, and when the AGV automatic guided vehicle moves under the first lifting mechanism, each second lifting assembly corresponds to a first lifting assembly, so that the electric vehicle can be transferred between the first lifting mechanism and the AGV automatic guided vehicle.

DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

The terms "first", "second", and "third" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance. In addition, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be a connection between the two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the embodiments of the present invention can be understood according to the specific circumstances.

[0030] like Figures 1 to 8 As shown, an embodiment of the present invention provides an electric vehicle transportation device, which includes a first lifting mechanism and an AGV automatic guided vehicle. In practical applications, the first lifting mechanism can be set up in the finished product area of ​​the assembly workshop and the inspection area of ​​the inspection workshop according to needs.

[0031] like Figure 1 As shown, the first lifting mechanism includes two symmetrically arranged first lifting structures 1. Specifically, the two first lifting structures 1 are symmetrically arranged to achieve lifting of the electric vehicle.

[0032] like Figure 5 As shown, the first lifting structure 1 includes a mounting seat 11, a first lifting assembly 12 and two first lifting assemblies 13. The first lifting assembly 12 is arranged on the mounting seat 11. The two first lifting assemblies 13 are both connected to the first lifting assembly 12, so that the first lifting assembly 12 can drive the first lifting assembly 13 to move along the height direction of the mounting seat 11, and the two first lifting assemblies 13 are arranged at intervals along the length direction of the mounting seat 11. The first lifting assembly 13 is configured to lift the wheels of the electric vehicle. In actual applications, the first lifting assembly 12 drives the first lifting assembly 13 to move along the height direction of the mounting seat 11 according to actual use requirements, so as to move the first lifting assembly 13 to a suitable height.

[0033] In practical applications, the width of the AGV is smaller than the distance between the two first lifting structures 1. Specifically, the width of the AGV is smaller than the distance between the two first lifting structures 1, so as to ensure that the AGV can enter between the two first lifting structures 1 without hindrance, thereby ensuring efficient transportation operations.

[0034] like Figure 2 As shown, the AGV automatic guided vehicle includes an automatic guided vehicle body 2 and a second lifting mechanism 3. The second lifting mechanism 3 includes two second lifting structures 31, and the two second lifting structures 31 are arranged at intervals along the length direction of the automatic guided vehicle body 2. The length direction of the automatic guided vehicle body 2 is consistent with the length direction of the mounting seat 11. The second lifting structure 31 includes a lifting plate 311, a second lifting assembly 312 and two second lifting assemblies 313. The second lifting assembly 312 is arranged on the automatic guided vehicle body 2. The lifting plate 311 is connected to the second lifting assembly 312 so that the second lifting assembly 312 can drive the lifting plate 311 to move along the height direction of the automatic guided vehicle body 2. In actual application, the second lifting assembly 312 can drive the lifting plate 311 to move along the height direction of the automatic guided vehicle body 2 to move the lifting plate 311 to a suitable height.

[0035] In actual application, the length direction of the lifting plate 311 is perpendicular to the length direction of the automatic guided vehicle body 2. Two second lifting components 313 are symmetrically installed on the lifting plate 311 along the length direction of the lifting plate 311, and when the AGV automatic guided vehicle moves under the first lifting mechanism, each second lifting component 313 corresponds to a first lifting component 13, so that the electric vehicle can be transferred between the first lifting mechanism and the AGV automatic guided vehicle. Specifically, when the AGV automatic guided vehicle moves under the first lifting mechanism and ensures that the four first lifting components 13 and the four second lifting components 313 correspond one to one, the AGV automatic guided vehicle stops moving.

[0036] The electric vehicle transportation device of the present application is provided with two first lifting mechanisms when in use, and the two first lifting mechanisms are respectively installed in the finished product area of ​​the general assembly workshop and the inspection area of ​​the inspection workshop. When there are finished electric vehicles that need to be transferred at the first lifting mechanism of the general assembly workshop, the AGV automatic guided vehicle will move to the first lifting mechanism of the general assembly workshop and accurately move to between the two first lifting structures 1. Then, by adjusting the position of the AGV automatic guided vehicle and the height of the lifting plate 311, the four first lifting components 13 and the four second lifting components 313 can correspond one to one, and the AGV automatic guided vehicle stops moving at this time; then, the second lifting component 312 drives the lifting plate 311 to continue to rise, so that the four second lifting components 313 lift the four wheels of the electric vehicle. As the lifting height increases, the electric vehicle will gradually leave the four first lifting components 13, thereby transferring the electric vehicle from the first lifting mechanism to the AGV automatic guided vehicle; then, the AGV automatic guided vehicle starts to move, driving the electric vehicle to the inspection area of ​​the inspection workshop. After arriving at the detection area, the AGV automatic guided vehicle moves to between the two first lifting structures 1 in the detection area. When the four first lifting components 13 and the four second lifting components 313 correspond one by one, the AGV automatic guided vehicle stops moving. Then the second lifting component 312 drives the lifting plate 311 to lower, so that the four first lifting components 13 can lift the four wheels of the electric vehicle. At this time, the four second lifting components 313 no longer have a lifting effect on the electric vehicle, thereby transferring the electric vehicle from the AGV automatic guided vehicle to the first lifting mechanism, and the AGV automatic guided vehicle can leave the first lifting mechanism for the next transfer operation. The electric vehicle transportation device of the present application will not have an effect on the battery pack, avoiding the risk of squeezing the battery pack, thereby protecting the battery safety, extending the battery life, and improving the overall performance and reliability of the electric vehicle. In addition, when bumpy roads are encountered during the transfer process, since the wheels of the electric vehicle are lifted, which is equivalent to the electric vehicle being on the ground, the electric vehicle's own shock absorption system can effectively ensure the balance of the electric vehicle, greatly reducing the vibration effect inside the electric vehicle, thereby improving the stability of electric vehicle transportation, reducing safety hazards during transportation, reducing potential damage caused by vibration, ensuring that the electric vehicle is not damaged during the transfer and inspection process, and providing consumers with high-quality products. At the same time, this highly stable transfer device also improves transfer efficiency and reliability, helps to improve the production efficiency and market competitiveness of electric vehicle manufacturers, and has strong practicality.

[0037] like Figure 3As shown, the first lifting assembly 12 includes a transmission bar 121 and two first electric telescopic rods 122. The length direction of the transmission bar 121 is consistent with the length direction of the mounting seat 11, and the two first lifting assemblies 13 are connected to the transmission bar 121. The two first electric telescopic rods 122 are arranged along the length direction of the mounting seat 11, and the fixed end of each first electric telescopic rod 122 is connected to the mounting seat 11, and the telescopic end is connected to the transmission bar 121. Specifically, the transmission bar 121 is driven to move along the height direction of the mounting seat 11 by the two first electric telescopic rods 122 working simultaneously to ensure that the transmission bar 121 is more stable during the movement process, thereby improving the reliability of the entire device. In actual applications, the ground clearance of the electric vehicle placed on the four first lifting assemblies 13 is adjusted by the first electric telescopic rod 122, so that the AGV automatic guided vehicle can smoothly enter the gap below the plane formed by the four first lifting assemblies 13.

[0038] like Figure 5 As shown, the first lifting assembly 12 further includes a baffle 123. The baffle 123 is connected to the end of the transmission bar 121. In practical applications, the baffle 123 can resist the front wheels of the electric vehicle, effectively improving the stability of the electric vehicle placed on the first lifting assembly 13. Specifically, when the AGV enters between the two first lifting structures 1, it needs to enter from the end away from the baffle 123.

[0039] like Figure 5 and Figure 6 As shown, the first lifting assembly 12 also includes a guide plate 124. The guide plate 124 is arranged between the two first lifting assemblies 13. A receiving groove 1211 for mounting the guide plate 124 is arranged on the transmission bar 121. When the guide plate 124 is mounted in the receiving groove 1211, the top of the guide plate 124 and the tops of the two first lifting assemblies 13 are located in the same plane. Specifically, the top of the guide plate 124 and the tops of the two first lifting assemblies 13 are located in the same plane, which can ensure that the electric vehicle can be driven out of the first lifting assembly 13, especially for the first lifting assembly 13 in the detection area. When the detection is carried out, the electric vehicle can be driven out of the first lifting assembly 13 for road testing, which is highly practical.

[0040] In practical applications, the first lifting assembly 13 includes at least two first lifting rods 131. At least two first lifting rods 131 are arranged at intervals along the length direction of the mounting seat 11, and each first lifting rod 131 is connected to the first lifting assembly 12. Specifically, the number of the first lifting rods 131 can be set according to actual needs to ensure that the wheel can be stably lifted.

[0041] In actual application, the second lifting assembly 312 includes an electric lifting frame. An adjustment slot 21 is provided on the top of the automatic guided vehicle body 2, and the adjustment slot 21 extends along the length direction of the automatic guided vehicle body 2. The electric lifting frame is installed in the adjustment slot 21 and is located at the end of the extension direction of the adjustment slot 21. The end of the electric lifting frame that is away from the adjustment slot 21 is connected to the lifting plate 311. Specifically, the electric lifting frame matches the lifting plate 311 and can drive the lifting plate 311 to rise and fall. At the same time, the two second lifting structures 31 can be independently lifted and lowered by the electric lifting frame. In addition, the electric lifting frame is positioned in the adjustment slot 21 to reduce the volume of the AGV automatic guided vehicle, so that the AGV automatic guided vehicle can more easily enter between the two first lifting structures 1.

[0042] In actual application, the second lifting assembly 313 includes at least two second lifting rods 3131. At least two second lifting rods 3131 are arranged at intervals along the length direction of the automatic guided vehicle body 2, and each second lifting rod 3131 is connected to the lifting plate 311. Specifically, the number of second lifting rods 3131 can be set according to actual needs to ensure that the wheels can be stably lifted. Furthermore, when the AGV automatic guided vehicle moves to a certain position between the two first lifting structures 1, the four first lifting assemblies 13 and the four second lifting assemblies 313 are opposite to each other, and for any relative first lifting assembly 13 and second lifting assembly 3131, the first lifting rods 131 and the second lifting rods 3131 are arranged in an alternating manner.

[0043] like Figure 3 As shown, the second lifting structure 31 also includes a positioning plate 314 and a third electric telescopic rod 315. The two positioning plates 314 are symmetrically arranged on the lifting plate 311 along the length direction of the lifting plate 311, and each positioning plate 314 is slidably connected to the lifting plate 311. Two third electric telescopic rods 315 are symmetrically arranged between the two positioning plates 314, and the fixed end of each third electric telescopic rod 315 is connected to the lifting plate 311, and the telescopic end of each third electric telescopic rod 315 is respectively connected to the positioning plate 314 at the corresponding position. Specifically, when the electric vehicle is lifted on the four second lifting components 313, the positioning plate 314 is driven by the third electric telescopic rod 315 to move in the direction of the electric vehicle wheel close to the corresponding position, so that the positioning plate 314 and the wheel of the electric vehicle are abutted, thereby greatly improving the stability of the electric vehicle when it is located on the second lifting component 313.

[0044] like Figure 7As shown, the AGV automatic guided vehicle also includes an adjustment mechanism 4. The adjustment mechanism 4 includes two adjustment structures 41, and the two adjustment structures 41 are both arranged between the two second lifting structures 31, and each adjustment structure 41 is respectively connected to a second lifting structure 31. The adjustment structure 41 includes two second electric telescopic rods 411. The fixed ends of the two second electric telescopic rods 411 are connected to the automatic guided vehicle body 2, and the telescopic ends of the two second electric telescopic rods 411 are connected to the second lifting structure 31. In actual applications, the two adjustment structures 41 can respectively drive the corresponding second lifting structures 31 to slide along the length direction of the automatic guided vehicle body 2, so that the positions of the two second lifting structures 31 in the length direction of the automatic guided vehicle body 2 can be independently adjusted, which can not only adapt to different electric vehicle models, but also can fine-tune the position of the second lifting component 313 to better match the wheels of the electric vehicle.

[0045] The electric vehicle transportation device provided in the embodiment of the present application also includes an on-board controller, a ground controller, a navigation module, a communication module and an alarm module. The on-board controller, the ground controller, the navigation module, the communication module and the alarm module are all arranged on the automatic guided vehicle body 2. The ground controller and the on-board controller are connected through the communication module to fine-tune and manage the automatic guided vehicle body 2. Specifically, the on-board controller is installed on the automatic guided vehicle body 2, which is the core control unit of the AGV automatic guided vehicle. It can receive information from the navigation module, the communication module, etc., and control the first electric telescopic rod 122, the second electric telescopic rod 411 and the third electric telescopic rod 315 and other structures according to the preset program and algorithm, so as to realize the functions of autonomous driving of the automatic guided vehicle body 2 and electric vehicle transportation. The on-board controller usually adopts a microcomputer or an embedded system, which has strong computing power and real-time performance. The navigation module uses a laser scanner, which obtains three-dimensional information of the environment by scanning objects in the surrounding environment, and then matches the scanned information with the pre-stored map to determine its own position and direction. Laser navigation has the advantages of high precision and flexible path planning. When the automatic guided vehicle body 2 encounters a fault or a dangerous situation, the alarm module will sound an alarm to alert the surrounding personnel to pay attention.

[0046] In practical applications, a first camera collector and a second camera collector are provided on the mounting seat 11. The first camera collector is used to collect video information of the first lifting assembly 13 in the final assembly workshop, so as to determine whether there is a finished electric vehicle on the first lifting assembly 13. The second camera collector is used to collect video information of the first lifting assembly 13 in the inspection workshop, so as to determine whether there is an electric vehicle on the first lifting assembly 13, so as to adapt to the transfer requirements of the newly produced electric vehicles.

[0047] The embodiment of the present application further provides a method for transporting an electric vehicle. Based on the electric vehicle transport device provided above, two first lifting mechanisms are respectively installed in the finished product area of ​​the general assembly workshop and the inspection area of ​​the inspection workshop, comprising the following steps:

[0048] The embodiment of the present application also provides a transportation method of an automatic transportation device for electric vehicles, wherein two first lifting mechanisms of the transportation device are respectively installed in an assembly workshop and a testing workshop, and the method comprises the following steps:

[0049] S1. Based on the ground controller, the information of the first camera collector in the final assembly workshop is obtained. If the ground controller recognizes that there is an electric vehicle on the first lifting mechanism, the automatic guided vehicle body 2 moves from the storage area to the first lifting mechanism in the final assembly workshop;

[0050] S2, based on the cooperation between the on-board controller and the ground controller, the four first lifting assemblies 13 and the four second lifting assemblies 313 are opposite to each other, and for any opposite first lifting assemblies 13 and second lifting assemblies 313, the first lifting rods 131 and the second lifting rods 3131 are arranged alternately, and the second lifting assembly 312 is controlled to be lifted and lowered, and the second lifting assembly 312 drives the lifting plate 311 to be lifted and lowered, so that the four second lifting assemblies 313 can lift the four wheels of the electric vehicle;
