Description

Technical Field

[0001] The present invention relates to electric vehicle battery replacement technology, and in particular to a lifting and positioning module and a container-type battery replacement vehicle. Background Art

[0002] Electric vehicles are currently the predominant form of new energy vehicles. After years of technological research and development, the range of some electric vehicles at full charge is now comparable to that of a typical fuel-powered vehicle. Consequently, concerns about electric vehicles primarily center on recharging (replenishing energy). Even with the most advanced technology available, charging a battery from zero to 80% takes approximately 30 minutes, while refueling a fuel-powered vehicle only requires a few minutes. Furthermore, current charging infrastructure is imperfect, and various brands of charging facilities cannot meet the fast-charging requirements of different electric vehicle brands. Under normal charging conditions, charging a battery from zero to 80% takes several hours, further exacerbating range anxiety. This assumes there's no waiting time for a charging station; if you need to queue for charging, the recharging period is even longer.

[0003] In this regard, the existing technology mainly tends to achieve rapid energy replenishment by replacing batteries, that is, removing the low-charged battery of the electric vehicle and then replacing it with a fully charged battery. The whole process takes only a few minutes, which is completely comparable to the energy replenishment efficiency of fuel vehicles. However, battery swap stations are expensive and require special personnel for maintenance. At the same time, a certain amount of battery swapping is required to maintain operations. Therefore, this method is currently mainly concentrated in urban areas with a large number of electric vehicles, while there are few in relatively remote suburbs, and even fewer in highway service areas and rural areas. Therefore, how to solve the layout of rapid battery swap stations, especially to meet the demand for temporary battery swap stations, is a problem that needs to be solved. Because traffic has certain patterns, such as in areas where vehicles temporarily gather and highway service areas on holidays, there is a large traffic flow and a high demand for battery replacement, but it is not suitable to set up permanent battery swap stations because this demand is only temporary.

[0004] In this regard, the present application proposes a container-type battery-swapping vehicle, which can be folded into the shape and size of a container, and quickly transported to the location where the battery needs to be replaced by a container, and then unfolded to start the battery replacement. When the demand for battery replacement is low, it can be folded up and transported to other required locations to flexibly provide battery replacement services while effectively solving the anxiety of electric vehicles replenishing energy. The two main problems that need to be solved in the battery replacement process are the lifting and positioning of the electric vehicle and the disassembly and replacement of the battery. The present invention also solves these two problems. Summary of the Invention

[0005] In view of the above-mentioned defects of the prior art, the technical problem to be solved by the present invention is to provide a lifting and positioning module and a container-type battery-changing vehicle thereof, wherein the lifting and positioning module can realize the lifting and positioning of the electric vehicle to facilitate the subsequent battery replacement.

[0006] To achieve the above objectives, the present invention provides a lifting and positioning module, which is installed on the outer box of the vehicle compartment and includes a lifting module and a positioning module. The lifting module is used to guide the electric vehicle to a higher position to complete the lifting. The positioning module positions the tires of the electric vehicle to achieve the positioning of the electric vehicle and the lifting module. The positioning module can be retracted and extended relative to the outer box. The lifting module includes a first lifting part, a second lifting part, and a folding mechanism. The first lifting part and the second lifting part are respectively equipped with a folding shaft seat. The folding shaft seat of the first lifting part is assembled with a folding shaft so as to be rotatable in a circular manner, while the folding shaft is assembled with the folding shaft seat of the second lifting part so as not to be rotatable in a circular manner. The folding mechanism is used to drive the second lifting part to rotate relative to the first lifting part around the folding shaft so as to realize rotation, folding or unfolding of the second lifting part relative to the first lifting part. The first lifting part is provided with a lifting shaft seat, which is hinged to the outer box through a lifting shaft; the lifting module is also provided with a hook hole, which can be hooked with a hook, and the hook is installed on one end of the cable, and the other end of the cable is installed in the winch, the winch is installed on the winch mounting seat, and the winch mounting seat is installed on the outer box.

[0007] The present invention also discloses a container-type battery-exchange vehicle, comprising the above-mentioned lifting and positioning module, a carriage, a pick-up and placement module, a transfer vehicle, and a storage module. The pick-up and placement module, the transfer vehicle, the lifting module, the storage module, and the positioning module are all installed on the carriage. The storage module is used to store batteries and charge the batteries at the same time; the pick-up and placement module is used to input or output batteries into or out of the storage module, and at the same time transport the batteries between the pick-up and placement module and the transfer vehicle; the transfer vehicle is used to transport batteries disassembled from electric vehicles to the pick-up and placement module, which is then stored in the storage module. The pick-up and placement module takes out the fully charged batteries in the storage module and then transfers them to the transfer vehicle. The transfer vehicle transports the fully charged batteries to the bottom of the electric vehicle and then loads the batteries into the electric vehicle to complete the battery replacement.

[0008] The beneficial effects of the present invention are: The lifting and positioning module of the present invention is divided into a lifting module for lifting the car and a positioning module for completing the positioning of the car and the lifting module. The lifting module can be folded and stored on the car body, thereby greatly improving the integration, which also indirectly provides a reference for the subsequent positioning of the electric car. At the same time, the lifting module guides the electric car to travel and lift through a retractable diagonal mechanism. It is not only simple in structure, but also achieves a highly integrated and storable design through the retractable design. The positioning module positions the two tires close to one side of the car body. During the positioning process, the vehicle can be pulled in the direction of the vehicle's wheelbase to complete the positioning of the vehicle. This design structure is simple, and the positioning point pressure method can achieve high-precision positioning, so as to provide a good positioning reference for subsequent battery replacement.

[0009] The battery exchange module of the present invention includes a transfer vehicle, a pick-and-place module, and a storage module. The pick-and-place module is used to transport the battery between the transfer vehicle and the storage module, and the lifting design of the transfer vehicle can effectively realize the lifting and lowering of the battery during the battery replacement process. At the same time, the battery is locked by a lock block and an annular groove and is independently unlocked and locked by the electric vehicle, which can omit the battery disassembly and assembly structure, thereby reducing the complexity of the structure and reducing costs. The storage modules can be integrated and used in a stacking manner. Each storage module realizes multi-channel storage by setting up multiple storage channels, and can realize the input and output of batteries one by one. At the same time, it has the function of charging the battery. While having all the functions of a fixed battery exchange station, it also has the advantages of high integration, easy transportation, flexible layout, etc. It can adapt to the situation of temporary increase in battery exchange demand and solve the anxiety of electric vehicle recharge.

[0016] See also Figures 1-14 The lifting module 400 includes a first lifting portion 400-1, a second lifting portion 400-2, and a folding mechanism 450. The first lifting portion 400-1 and the second lifting portion 400-2 have the same structure.

The first lifting part 400-1 includes a lifting frame 410, a diagonal mechanism 420, a side rolling assembly 430, and a switch plate 440. The lifting frame 410 is provided with a battery replacement half slot 411, a side rolling installation slot 412, a folding axle seat 413, and a switch plate bracket 414. The diagonal mechanism 420 is installed at both ends of the lifting frame 410; the side rolling assembly 430 is installed in the side rolling installation slot 412 and the side rolling assembly 430 is composed of a plurality of rollers that can rotate in a circle and is used to guide the electric vehicle 01 to move toward the outer box 110; the switch plate bracket 414 is installed on the lifting frame 410 and is connected to the lifting frame A switch plate slot is formed between 410, and the switch plate 440 is snap-fitted and slidably installed in the switch plate slot. When the switch plate 440 is closed, the battery exchange half slot 411 is completely closed, and when it is opened, it does not block the battery exchange half slot 411. The switch plate 440 is assembled with the switch plate electric cylinder shaft 4411, and the switch plate electric cylinder shaft 4411 is installed in the switch plate electric cylinder 441. The switch plate electric cylinder 441 is directly or indirectly installed on the lifting frame 410. After the switch plate electric cylinder 441 is started, it can drive the switch plate electric cylinder shaft 4411 to axially extend and retract, thereby driving the switch plate 440 to slide synchronously so that the switch plate 440 opens or closes the battery exchange half slot 411.

[0017] The oblique mounting mechanism 420 is used to form an inclined surface to guide the electric vehicle 01 to drive onto the lifting frame 410 so as to achieve the purpose of lifting the electric vehicle 01. The oblique mounting mechanism 420 of this embodiment includes a first oblique mounting seat 421, a second oblique mounting seat 422, a third oblique mounting seat 423, an oblique mounting fixed seat 424, and an oblique mounting electric cylinder 427. The outer walls of the first oblique mounting seat 421, the second oblique mounting seat 422, and the third oblique mounting seat 423 are respectively installed with oblique guide rails 425. The outer walls of the first oblique mounting seat 421 are respectively installed with oblique guide rails 425. The oblique guide rail 425 is inserted into the second oblique seat 422 and is slidably assembled therewith. The oblique guide rail 425 of the second oblique seat 422 is inserted into the third oblique seat 423 and is slidably assembled therewith. The oblique guide rail 425 of the third oblique seat 423 is inserted into the oblique fixed seat 424 and is slidably assembled therewith. The second oblique seat 422, the third oblique seat 423 and the oblique fixed seat 424 are respectively provided with an oblique limiting shaft 426. The oblique limiting shaft 426 of the second oblique seat 422 is The shaft 426 is installed in the oblique guide rail 425 of the first oblique seat 421 to limit the maximum displacement of the first oblique seat 421 relative to the second oblique seat 422, the oblique limiting shaft 426 of the third oblique seat 423 is installed in the oblique guide rail 425 of the second oblique seat 422 to limit the maximum displacement of the second oblique seat 422 relative to the third oblique seat 423, and the oblique limiting shaft 426 of the oblique fixing seat 424 is installed in the oblique guide rail 425 of the third oblique seat 423 to limit the maximum displacement of the third oblique seat The maximum displacement of the mounting seat 423 relative to the diagonal mounting fixed seat 424; the diagonal mounting fixed seat 424 is installed on the lifting frame 410, and the first diagonal mounting seat 421 is assembled with the diagonal electric cylinder shaft 4271 of the diagonal electric cylinder 427, and the diagonal electric cylinder 427 is directly or indirectly installed on the lifting frame 410. After the diagonal electric cylinder 427 is started, the diagonal electric cylinder shaft 4271 is driven to extend and retract, thereby driving the first diagonal mounting seat 421, the second diagonal mounting seat 422, and the third diagonal mounting seat 423 to extend and retract relative to the diagonal mounting fixed seat 424. Figure 13 The figure shows the state where the diagonal mounting mechanism 420 is retracted relative to the lifting frame 410. Figure 4 The diagonal mounting mechanism 420 is shown fully extended relative to the elevating frame 410. This design is primarily due to the fact that the slope of the diagonal mounting mechanism 420 is not steep, so the overall length of the diagonal mounting mechanism 420 needs to be increased to increase the height at which the diagonal mounting mechanism 420 guides the electric vehicle 01, thereby meeting the height requirement during battery swapping. However, increasing the overall length of the diagonal mounting mechanism 420 would make storage inconvenient. Therefore, in this embodiment, the diagonal mounting mechanism 420 is configured to be telescopically extended and retracted to meet both the height requirement and the storage requirement.

[0018] The folding shaft seat 413 of the first raised portion 400-1 is assembled with the folding shaft 460 so as to be rotatable in a circular manner, and the folding shaft 460 is assembled with the folding shaft seat 413 of the second raised portion 400-2 so as not to be rotatable in a circular manner; the folding shaft 460 is mounted with a folding power tooth 461, which is meshed with a folding intermediate tooth 471 for transmission, and the folding intermediate tooth 471 is meshed with a folding active tooth 481 for transmission, and the folding intermediate tooth 471 and the folding active tooth 481 are mounted on the folding intermediate shaft respectively. 470, folding driving shaft 480, the said folding intermediate shaft 470, folding driving shaft 480 are all mounted on folding housing 451, folding driving shaft 480 is also mounted on folding worm gear 482, folding worm gear 482 and folding worm 483 are meshed and driven, folding worm 483 is arranged or mounted on folding motor shaft 4521, the said folding motor shaft 4521 is installed in folding motor 452, folding motor 452 is mounted on folding housing 451, folding housing 451 is mounted on first elevating part 400-1. After starting, the said folding motor 452 can drive folding motor shaft 4521 to rotate in a circle, thereby driving folding shaft 460 to rotate, folding shaft 460 drives second elevating part 400-2 to rotate, so as to realize folding rotation and unfolding rotation between second elevating part 400-2 and first elevating part 400-1. In this embodiment, the folding motors 452 are servo motors and there are two of them, which can provide sufficient torque to drive the second lifting portion 400-2 to rotate, and the two folding motors 452 can achieve synchronous rotation. The folding housing 451 and its internal components, and the folding motors 452 together constitute the folding mechanism 450.

[0019] In the initial state, the second lifting part 400-2 and the first lifting part 400-1 are in a folded state, which can effectively reduce the height of the outer box 110 occupied by the lifting module 400 when it is rotated and retracted toward the outer box 110, thereby reducing the height of the outer box 110 and increasing the convenience of transportation. When in use, first open the sun visor 120, then release the cable 141 to rotate the entire lifting module 400 relative to the outer box 110 until the first lifting part 400-1 contacts and presses against the ground, and then start the folding motor 452, which drives the second lifting part 400-2 to unfold and rotate to Figure 4 State, and then insert the support rod 130 into the rod seat 402 to complete the installation of the sun visor 120. When battery replacement is required, in order to prevent the battery replacement half-slot 411 from affecting the passage of the electric vehicle 01, this embodiment provides a switch plate 440 to close the battery replacement half-slot 411 to ensure the safe passage of the electric vehicle 01. After the electric vehicle 01 completes positioning, the switch plate 440 is opened to pass through the battery replacement half-slot 411 of the second raised portion 400-2 and the first raised portion 400-1 to achieve the passage of the battery 03 and the transfer machine 300, thereby successfully completing the battery replacement.

[0020] See also Figure 3-Figure 4 、 Figure 14 、 Figures 26-30 The positioning module 600 is used to position the electric vehicle 01 on the lifting module 400, specifically to position the two tires 02 of the electric vehicle 01 on the side close to the outer box 110, so as to realize the positioning of the electric vehicle 01 and the lifting module 400. The positioning module 600 includes a movable positioning module 600-1 and a fixed positioning module 600-2. The movable positioning module 600-1 and the fixed positioning module 600-2 both include a positioning fixed frame 610, a positioning movable frame 620, an end face positioning assembly 630, a lateral positioning assembly 640, a positioning motor 651, and a support wheel frame 680.

After the lateral cylinder 652 is started, it can drive the lateral bracket 621 to slide relative to the positioning movable frame 620.

[0021] The movable frame rack 664 meshes with the movable frame gear 665 for transmission. The movable frame gear 665 is mounted on a movable frame pinion 670. One end of the movable frame pinion 670 is connected to the output shaft of the positioning motor 651. The movable frame pinion 670 and the positioning motor 651 are both mounted on the positioning fixed frame 610. When the positioning motor 651 is activated, it can drive the movable frame pinion 670 to rotate, thereby driving the positioning movable frame 620 to slide via the movable frame gear 665. The positioning motor 651 is a motor with a brake function.

[0022] The support wheel frame 680 is installed at the bottom of the positioning movable frame 620 and a support wheel 681 is installed on the support wheel frame 680 so as to be rotatable in a circular motion. The support wheel 681 is pressed against the end surface of the outer box bottom plate 160 to supplement the support for the positioning movable frame 620.

The other end of the end face guide shaft 632 is fitted with the end face spring 633 and then installed within the housing of the end face positioning assembly 630. The other end of the end face contact rod 634 is installed within the housing of the end face positioning assembly 630 and contacts or connects to the input shaft of the end face pressure sensor 653. The end face spring 633 exerts a spring force on the end face contact plate 631, preventing it from moving toward the housing of the end face positioning assembly 630. During use, the end face of the wheel 02 presses against the end face contact plate 631, causing it to overcome the spring force of the end face spring 633 and move toward the housing of the end face positioning assembly 630 until the pressure of the end face pressure sensor 653 reaches a preset threshold. If the pressures output by the end face pressure sensors 653 of the movable positioning module 600-1 and the fixed positioning module 600-2 reach the preset threshold and the two measured pressures are within the preset difference range, it can be determined that the end face direction of the tire 02 of the electric vehicle 01 is positioned (the width direction of the electric vehicle 01 and the lifting module 400 are positioned).

The other end of the lateral guide shaft 642 is fitted with the lateral spring 643 and then inserted into the lateral positioning shell 647. The lateral spring 643 provides elastic damping for the lateral touch plate 641 to move toward the lateral positioning shell 647. The other end of the lateral touch rod 644 is inserted into the lateral positioning shell 647 and then contacts or is connected to the input shaft of the lateral pressure sensor 654. The lateral pressure sensor 654 is installed in the lateral positioning shell 647. During use, the outer ring of tire 02 presses against lateral contact plate 641, causing it to move toward lateral positioning housing 647 against the elastic force of lateral spring 643. Lateral contact rod 644 presses against the input shaft of lateral pressure sensor 654 until the pressure output by lateral pressure sensor 654 reaches a preset threshold. If the pressures of lateral pressure sensors 654 on both movable positioning module 600-1 and fixed positioning module 600-2 reach the preset threshold and both measured pressures are within a preset differential range, it can be determined that electric vehicle 01 has been successfully positioned relative to lifting module 400 in the wheelbase direction.

The power spring 504 applies a thrust to the conductive block 548 away from the closed end of the electric seat slot 5511; the conductive block 548 is electrically connected to one end of the conductive column 549, and the other end of the conductive column 549 passes through the insulating tube 590 and is electrically connected to the cable so that power can be supplied to the conductive block 548. The conductive block 548 is pressed against the electrode column 05 to conduct electricity so that the battery 03 can be charged. After the battery 03 is fully charged, the power cylinder 547 drives the conductive block 548 into the electric seat slot 503 to separate from the electrode column 05 to end charging.

[0042] A fan 541 is also installed at the location of the ventilation plate 512 corresponding to the placement of the battery 03. The air intake of the fan 541 is connected to the air gap 511, and the air outlet faces the corresponding battery 03. When in use, the fan 541 is activated to blow air towards the battery 03, thereby reducing the temperature of the battery 03. Of course, for even greater cooling effect, a coiled cooling tube can be installed in the air gap 511. A flowing refrigerant (such as cold water) can be connected to the cooling tube to reduce the temperature of the air entering the fan 541 (similar to existing air coolers), thereby further cooling the battery 03.

[0043] The process of placing batteries in the storage module 500 of this embodiment is as follows: S1, each storage channel only holds two batteries, and each storage module 500 has two storage channels; S2. When the first battery 03 enters the storage channel, the storage conveyor belt 520 is started to transport the battery 03 to the placement position farthest from the baffle plate 517. Then, the first screw motor 542 or the second screw motor 543 corresponding to this conveying channel is started to move the corresponding two first storage seats 581 or two second storage seats 582 into this storage channel until the sides of the two first storage seats 581 or two second storage seats 582, the sides of the corresponding storage outer plates 513, and the sides of the storage inner plates 514 are in close contact with the sides of the battery entering this time, completing the positioning and fixation of the battery 03 this time. If the batteries in S3 and S2 need to be charged, the corresponding power connection mechanism 550 is activated, so that the corresponding conductive block 548 is in close contact with the electrode column 05 for electrical conduction. At the same time, the fan can be activated as needed to dissipate heat.

[0044] When the storage channel in S4 and S2 needs to accommodate a second battery 03, the corresponding lifting cylinder 544 of the positioned battery 03 in S3 is activated to drive the corresponding lifting plate 513 upward, thereby lifting the battery 03 in S3 and separating it from the corresponding storage conveyor 520. The second battery 03 is then loaded until the battery edge 04 of the second battery 03 is aligned with the corresponding two first storage holders 581 or two second storage holders 582. The baffle cylinder 546 is activated, and its telescopic shaft retracts, driving the rotating baffle 517 to rotate toward the second battery 03 until it is pressed against the second battery 03, thereby positioning and securing the second battery 03. If the second battery needs to be charged at this time, the corresponding power connection mechanism 550 and fan 541 can be activated.

[0045] The process of outputting batteries from the storage module 500 of this embodiment is as follows: S1: There are two batteries 03 in the storage channel, and when the batteries 03 need to be output, the battery 03 that first enters the storage channel is kept in the lifted state of the lifting plate 531; S2, start the baffle electric cylinder 546 to open the rotating baffle 517, start the storage conveyor belt 520 to output the battery 03 into the storage channel; When S3 needs to output the battery 03 that enters the storage channel, the lifting plate 531 corresponding to the battery 03 moves downward so that the battery 03 is placed on the storage conveyor belt 520; the two first storage seats 581 or the two second storage seats 582 corresponding to the battery 03 move away from each other so as not to block the passage of the battery 03; and the storage conveyor belt 520 is started to output the battery 03.

[0046] S4. If the storage channel has three or more battery placement positions, two first storage holders 581 or two second storage holders 582 are installed between the two battery placement positions, and a lifting plate 531 is set for each battery placement position. When outputting the battery 03 of this storage channel, the battery 03 close to the baffle plate 517 can be output in sequence.

[0047] S5. If both ends of the storage channel can output batteries 03, a rotating baffle 517 and a baffle electric cylinder 546 need to be respectively provided at both ends. At this time, the batteries can be output one by one according to the output direction.

[0048] In this embodiment, when transporting batteries between the forking belt 251 and the storage conveyor belt 520, the forking belt 251 can be moved close to one end of the corresponding storage conveyor belt 520 first, and then the battery 03 can be transferred through the forking belt 251 and the storage conveyor belt 520.

[0049] The storage module 500 of this embodiment is installed in the outer box 110 (on the outer box bottom plate 160), and can be stacked according to the height inside the outer box, so that as many storage modules 500 as possible can be installed, and more battery storage positions can be provided, thereby meeting the needs of more battery-swapping vehicles. At the same time, if it is convenient to access the mains, it can be connected to the mains to provide electricity. If it is not convenient to access the mains, a fuel generator or a hydrogen generator can be installed to meet the supply of electricity. If it is not convenient to install a fuel generator, a larger battery pack can be installed to provide electricity. In actual use, multiple battery swap stations can be set up according to the needs of battery swapping. If a fully charged battery is used up during the battery swapping process, it can be directly put away and replaced with another battery swapping vehicle, thereby realizing continuous battery swapping.
