Description

Technical Field

[0001] The utility model relates to a side battery swapping system for new energy vehicles, belonging to the technical field of battery swapping for new energy vehicles. Background Technique

[0002] As a new type of transportation vehicle, new energy vehicles use storage batteries as energy storage power sources. Electric energy is provided by the battery to drive the motor to operate, thereby driving the vehicle to travel. They have advantages such as zero emissions and a wide range of energy sources. They are an important means to alleviate the shortage of oil resources and urban air pollution, and are an effective carrier to promote the transformation of the transportation development mode and the work of energy conservation and emission reduction.

[0003] However, the backwardness of relevant battery and charging technologies has become the main factor restricting the development of the new energy vehicle industry. New energy vehicles also have the greatest concerns for consumers when purchasing new energy vehicles due to short battery life, long charging time, and few charging facilities. Although the government and enterprises are making great efforts to improve the supporting charging infrastructure industry for electric vehicles, it is still difficult to solve the problem of charging and energy replenishment for people at present, and this situation is particularly prominent during holidays.

[0004] Currently, among new energy vehicles with the largest usage, private cars account for a considerable proportion. It is difficult for people to spare time to deal with the problem of charging and energy replenishment for new energy vehicles. Therefore, the fundamental method to overcome the development bottleneck of new energy vehicles is rapid battery swapping. Replacing the battery has become one of the rapid energy replenishment methods for new energy vehicles. When the battery decays to the point where it needs to be replaced, the battery is replaced in a timely manner to achieve rapid battery swapping for new energy vehicles, which is as convenient and fast as replacing the gas cylinder of a gas vehicle. For this reason, a lot of research and development has been done in this regard, and similar battery swapping stations in China have also been in a stage of rapid development.

[0005] However, since the battery of a new energy vehicle is installed on the chassis between the front and rear wheels of the vehicle, it is necessary to replace the battery from the bottom. Specifically, when the new energy vehicle arrives, the chassis of the new energy vehicle is lifted, and then the battery module on the vehicle chassis is removed as a whole for replacement. To meet the requirements of the battery life of new energy vehicles, the battery is generally heavy, and bottom battery swapping is not conducive to the taking and placing of the battery. In addition, the transfer and storage of the replaced battery and the transfer operation of the fully charged battery are not convenient. Moreover, bottom battery swapping also requires a professional platform, an operating space needs to be set at the bottom, and a deep enough pit needs to be supported. Therefore, this bottom battery swapping method limits the battery swapping efficiency of new energy vehicles; not only that, the battery swapping station requires a large floor space, and the requirements for the installation space of this battery swapping station are also not conducive to its popularization and application in cities. Content of the Utility Model

[0006] Aiming at the deficiencies of the existing technology, the utility model provides a side battery swapping system for new energy vehicles.

[0007] The technical solution of the utility model to solve the above technical problems is as follows: a new energy vehicle side battery swap system, including a side battery swap platform, a battery swap vehicle device, a battery compartment and a vehicle lifting mechanism, and also including a side battery swap port, the side battery swap port is arranged on the side of the new energy vehicle close to the battery swap vehicle device, the vehicle lifting mechanism can lift the vehicle traveling to the vehicle fixed position to the vehicle swap point, and the battery swap vehicle device is arranged between the vehicle fixed position and the battery compartment;

[0008] The battery-changing vehicle device includes a battery carrying platform, a battery rotating mechanism for driving the battery carrying platform to rotate, a battery lifting mechanism for driving the battery carrying platform to lift and lower, and a battery walking mechanism for driving the battery carrying platform to move forward and backward;

[0009] The battery supporting platform includes a platform body and a battery module traction device arranged on the platform body. The battery module traction device can take out the battery module to be replaced from the side battery replacement port of the vehicle and transfer it into the battery compartment, and can take out the battery module that has been charged in the battery compartment and insert it into the vehicle.

[0010] The beneficial effect of the utility model is that the new energy vehicle can be lifted from the vehicle fixed position to the vehicle swapping position by the vehicle lifting mechanism. The purpose of lifting here is to meet the horizontal positioning of the vehicle when swapping batteries, rather than to increase the operating space at the bottom of the vehicle. Therefore, the lifting stroke requirement is small, as long as the tires of the vehicle can be lifted off the side swapping platform. The space under the side swapping platform of the side swapping system is not an operating space, so the space does not need to be too large, and a shallow pit can be set up or the platform can be used to perform side swapping operations without digging a pit, which is convenient for the promotion and distribution of the side swapping system in the city. The overall operation of the side battery swap system is carried out on the side battery swap platform. As long as the new energy vehicle drives onto the side battery swap platform, it can realize automatic alignment safely and quickly. There is no additional driving skill requirement for the driver. By adapting the installation method of the new energy vehicle battery, the battery module can be inserted and pulled out from the side battery swap port on the battery swap side, and the battery module can be quickly replaced using the battery swap vehicle device. Under normal circumstances, the vehicle can complete the side battery swap operation in 3-5 minutes, realizing the rapid battery swap of new energy vehicles. Its speed is comparable to the refueling time of oil vehicles, and the driver no longer has to worry about waiting time. The utility model has a simple structure, and the entire side battery swap process is convenient, fast, safe, and visible, which greatly improves the battery swap efficiency of new energy vehicles. In addition, the side battery swap requires a small space and has a low site construction cost, which is conducive to the promotion and application of the side battery swap system.

[0011] On the basis of the above technical solution, the present invention can also be improved as follows.

[0012] Further, it further includes a battery installation frame provided on a new energy vehicle. A frame chute or a frame slide rail for guiding and limiting the incoming and outgoing battery modules is provided in the battery installation frame. A vehicle-end electrical connector and a vehicle-end water connector are provided on one side of the battery installation frame. The battery-end electrical connector of the battery module is inserted and mated with the vehicle-end electrical connector to supply power to the new energy vehicle. The battery-end water connector of the battery module is hermetically docked with the vehicle-end water connector to dissipate heat and cool down the battery module.

[0013] The beneficial effect of adopting the above further solution is that corresponding battery modules and in-vehicle battery installation frames can be configured for different vehicle models. The in-vehicle of the new energy vehicle is equipped with a corresponding battery installation frame, and the battery module can be inserted into the battery installation frame. The battery installation frame is provided with a frame chute or a frame slide rail adapted to the battery module, which can realize stable and accurate positioning of the battery module. Moreover, after the battery module is inserted into the battery installation frame of the new energy vehicle, the battery-end electrical connector of the battery module is inserted and mated with the vehicle-end electrical connector, and the battery module can meet the power supply requirement of the new energy vehicle through the vehicle-end electrical connector on the battery installation frame. The battery-end water connector of the battery module can also be hermetically docked with the vehicle-end water connector, and the battery module can meet the requirement of connecting with the refrigerant of the new energy vehicle to dissipate heat and cool down the battery module through the vehicle-end water connector on the battery installation frame, thereby extending the service life of the battery module.

[0014] Further, a battery fixing structure is further provided on the battery installation frame. The battery fixing structure includes at least one fixed electromagnet. The fixed electromagnet is arranged on the same side as the vehicle-end electrical connector and the vehicle-end water connector. A first ferromagnetic structure adapted to the fixed electromagnet is correspondingly provided on one end face of the battery module.

[0015] The beneficial effect of adopting the above further solution is that the first ferromagnetic structure can be a steel plate, an iron plate or other structures. When the battery module is inserted into the battery installation frame of the new energy vehicle, the first ferromagnetic structure can be adsorbed and mated with the fixed electromagnet to realize stable positioning of the battery module. At the same time, when battery replacement is required, the separation of the battery module from the battery installation frame is convenient. For example, when the battery module needs to leave the battery installation frame, the fixed electromagnet is energized to demagnetize, and the battery module is separated from the battery installation frame, and the battery module can be pulled out of the battery installation frame to facilitate meeting the battery replacement requirement.

[0016] Further, the battery module traction device includes a traction table, a traction electromagnet and a traction driving mechanism. The traction electromagnet is arranged on the traction table. The traction table can move on the platform body under the action of the traction driving mechanism. A second ferromagnetic structure adapted to the traction electromagnet is provided on the other end face of the battery module.

[0017] The beneficial effects of adopting the above further solution are as follows: The traction platform moves towards the battery module under the action of the traction drive mechanism. The traction electromagnet adsorbs and cooperates with the second ferromagnetic structure of the battery module. When the traction drive mechanism operates, the traction platform can drive the battery module away from the vehicle or the battery compartment; when the battery corresponds to the side battery swapping port of the vehicle or the position of the battery compartment, the traction platform needs to drive the battery to push the battery into the vehicle or the battery compartment; the second ferromagnetic structure can be structures such as steel plates and iron plates.

[0018] Further, the battery compartment includes a compartment body, and multiple layers of positions are provided on the compartment body. Each layer has multiple positions, and the multiple positions are arranged in a matrix. Each position is provided with a pallet and a positioning component. The positioning component includes a pair of oppositely arranged positioning guide plates. The pair of positioning guide plates act on both sides of the battery module. The acting surface of the positioning guide plate is a guiding inclined surface, and the pair of guiding inclined surfaces are in a horn-shaped structure.

[0019] The beneficial effects of adopting the above further solution are as follows: The battery compartment makes full use of the space in the height direction, occupies a small area, has many positions, and can store multiple battery modules. The storage capacity of the battery modules is large. The battery modules to be charged can enter the corresponding positions of the battery compartment through the pallet and the positioning component, which is not only convenient and fast for entry and exit, but also accurate in positioning. The battery compartment can not only charge the battery modules, but also temporarily store the fully charged battery modules for use in new energy vehicle battery swapping.

[0020] Further, the position for charging is provided with a compartment end electrical connector and a compartment end water connector. The battery end electrical connector of the battery module can be inserted and cooperated with the compartment end electrical connector to charge the battery module. The battery end water connector of the battery module can be hermetically docked with the compartment end water connector to cool and dissipate heat from the battery module.

[0021] The beneficial effects of adopting the above further solution are as follows: When the battery module is charged in the battery compartment, the temperature of the battery module will increase. Therefore, the battery end water connector on the battery module can be hermetically docked with the compartment end water connector, and the cooling flow channels inside the battery module and the refrigerant of the battery compartment are connected, so as to dissipate heat from the battery module and extend the service life of the battery module.

[0022] Further, the side battery swapping platform is also provided with a vehicle alignment and positioning mechanism for adjusting the front, rear, left, and right positions of the incoming vehicle. The vehicle alignment and positioning mechanism includes a pair of front wheel positioning mechanisms and a pair of rear wheel positioning mechanisms;

[0023] The front wheel alignment mechanism includes a front roller row assembly for supporting the front wheels of the vehicle and a front wheel left-right shifting assembly for adjusting the left-right position of the new energy vehicle. The front roller row assembly has a concave structure. The rear wheel alignment mechanism includes a rear roller row for supporting the rear wheels and a rear wheel left-right shifting assembly for adjusting the left-right position of the new energy vehicle.

[0024] The beneficial effect of adopting the above further solution is that after the vehicle drives into the side battery swapping platform, the front roller row assembly with a concave structure can limit the front and rear positions of the front wheels of the vehicle. The rear roller row can support and position the rear wheels of the vehicle. After the front and rear positions of the vehicle are positioned, the left-right position of the vehicle can also be adjusted through the front wheel left-right shifting assembly and the rear wheel left-right shifting assembly, so that the vehicle can be centered. The front and rear and left-right positions of the vehicle driving into the side battery swapping platform are adjusted and positioned through the vehicle alignment mechanism, so as to ensure that the vehicle on the side battery swapping platform can meet the position requirements for side battery swapping of the new energy vehicle, facilitating the replacement of the battery module.

[0025] Further, there is one or more vehicle lifting mechanisms. The vehicle lifting mechanism includes a bearing frame, a lifting frame, and a lifting assembly arranged between the bearing frame and the lifting frame for driving the lifting frame to move up and down. There is an opening on the side battery swapping platform, and the vehicle lifting mechanism is arranged at the opening. The bearing frame is fixedly arranged or has an adjustable position below or at the bottom of the side battery swapping platform. The lifting frame is provided with a lifting plane or lifting points for lifting and leveling the new energy vehicle.

[0026] The beneficial effect of adopting the above further solution is that when the vehicle drives into the side battery swapping platform and needs battery swapping, in order to meet the requirements of the side battery swapping port position, the vehicle can be lifted and leveled through the vehicle lifting mechanism. Specifically, the lifting plane or lifting points of the lifting frame can be used to lift and level the vehicle, so as to meet the requirements for the smooth extraction and insertion of the battery module from the vehicle or the battery installation frame of the vehicle during side battery swapping.

[0027] Further, there are two lifting points for each vehicle lifting mechanism. The height direction of the lifting points is adjustable, the distance between the lifting points on the same vehicle lifting mechanism is adjustable, and the position of the bearing frame is adjustable under the action of the front and rear moving mechanism.

[0028] The beneficial effects of adopting the above further scheme are as follows: the height direction of the lifting points can also be adjusted independently, preparing for the leveling of new energy vehicles. The positions between the lifting points on the lifting mechanism of the same vehicle are adjustable, and the lifting points between the lifting mechanisms of different vehicles can also be adjusted through the front-back moving mechanism. The adjustability of the front-back position and left-right position of the lifting points enables the vehicle lifting mechanism to be applicable to the lifting and leveling of more different models of new energy vehicles, ensuring that the battery module can be in a horizontal state at the vehicle replacement position and facilitating the extraction and insertion of the battery module.

[0029] Further, the battery traveling mechanism includes a moving platform and a traveling driving mechanism for driving the moving platform to move back and forth along the traveling track. The traveling track is arranged along the front-back direction of the vehicle. The battery lifting mechanism is arranged on the moving platform, and the battery rotating mechanism is arranged between the battery lifting mechanism and the platform body.

[0030] The beneficial effects of adopting the above further scheme are as follows: the battery carrying platform can move along the traveling track under the action of the battery traveling mechanism, that is, move along the front-back direction of the vehicle. On the one hand, it can correspond to the side battery replacement port of the vehicle to facilitate the taking and placing of the battery module. On the other hand, it can align with the battery compartment to facilitate inserting the battery module to be charged into the compartment for charging and removing the fully charged battery module from the corresponding compartment.

[0058] The principles and features of the present utility model are described below in conjunction with examples. The examples given are only for explaining the present utility model and are not intended to limit the scope of the present utility model.

[0059] As Figures 1 - 26As shown in the figure, a new energy vehicle side battery swapping system includes a side battery swapping platform 1, a battery swapping vehicle device 2, a battery compartment 3, and a vehicle lifting mechanism 4. A vehicle fixing position is provided on the side battery swapping platform 1. The side battery swapping port of the new energy vehicle 7 is arranged on the side of the new energy vehicle 7 close to the battery swapping vehicle device 2. The vehicle lifting mechanism 4 can lift the vehicle driving to the vehicle fixing position to the vehicle battery swapping position. The battery swapping vehicle device 2 is arranged between the vehicle fixing position and the battery compartment 3;

[0060] The battery swapping vehicle device 2 includes a battery carrying platform, a battery rotating mechanism 205 for driving the battery carrying platform to rotate, a battery lifting mechanism 206 for driving the battery carrying platform to perform a lifting action, and a battery traveling mechanism for driving the battery carrying platform to move forward and backward;

[0061] The battery carrying platform includes a platform body 201 and a battery module traction device arranged on the platform body 201. The battery module traction device can take out the battery module 6 to be swapped from the side battery swapping port of the vehicle and transfer it into the battery compartment 3, and can take out the battery module 6 fully charged in the battery compartment 3 and insert it into the vehicle.

[0062] The number of the battery swapping vehicle devices 2 can be selected according to the actual situation. For example, Figure 1 and Figure 3 As shown in the figure, 2 battery swapping vehicle devices are shown in the figure. For example, Figure 25 and Figure 26 As shown in the figure, 1 battery swapping vehicle device is shown in the figure.

[0063] It further includes a battery installation frame 5 arranged on the new energy vehicle 7. A frame chute 501 or a frame slide rail for guiding and limiting the incoming and outgoing battery modules 6 is arranged in the battery installation frame 5. A vehicle end electrical connector 502 and a vehicle end water connector 503 are arranged on one side of the battery installation frame 5. The battery end electrical connector 603 of the battery module 6 is inserted and matched with the vehicle end electrical connector 502 to supply power to the new energy vehicle 7. There is a flow channel for cooling and heat dissipation in the battery module 6. A heat dissipation interface communicating with the flow channel is arranged on the battery module 6. A battery end water connector 604 is arranged at the heat dissipation interface. The battery end water connector 604 of the battery module 6 is hermetically docked with the vehicle end water connector 503 to dissipate heat and cool down the battery module 6.

[0064] On both sides of the battery installation frame 5, there are respectively frame chutes 501 for guiding and limiting the battery module 6; on both sides of the battery module 6, there are respectively battery sliders 605 that match the frame chutes 501. Through the cooperation of the battery sliders 605 and the frame chutes 501, it is ensured that the position of the battery module 6 inserted into the battery installation frame 5 is accurate, and it also prepares for the accurate docking of the battery terminal electrical connector 603 and the battery terminal water connector 604 on the battery module 6 with the vehicle terminal electrical connector 502 and the vehicle terminal water connector 503 on the battery installation frame 5.

[0065] The battery installation frame 5 is also provided with a battery fixing structure, and the battery fixing structure includes at least one fixed electromagnet 504. The fixed electromagnet 504, the vehicle terminal electrical connector 502, and the vehicle terminal water connector 503 are arranged on the same side of the battery installation frame 5. On one end face of the battery module 6, there is correspondingly arranged a first ferromagnetic structure 601 that cooperates with the fixed electromagnet 504.

[0066] For example, two fixed electromagnets 504 can be arranged on the battery installation frame 5. The two fixed electromagnets 504 are respectively located outside the vehicle terminal electrical connector 502 and the vehicle terminal water connector 503. Two first ferromagnetic structures 601 are arranged on the corresponding end face of the battery module 6. After the battery module 6 is inserted into the battery installation frame 5, the adsorption cooperation between the first ferromagnetic structure 601 and the fixed electromagnet 504 realizes the stable positioning of the battery module 6 on the battery installation frame 5.

[0067] The battery module traction device includes a traction table 202, a traction electromagnet 203, and a traction drive mechanism for driving the traction table 202 to move horizontally on the platform body 201. The traction electromagnet 203 is arranged on the traction table 202. The traction table 202 can move on the platform body 201 under the action of the traction drive mechanism. On the other end face of the battery module 6, there is a second ferromagnetic structure 602 that can cooperate with the traction electromagnet 203. The adsorption cooperation between the second ferromagnetic structure 602 and the traction electromagnet 203 realizes the stable positioning of the battery module 6 and the traction table 202.

[0068] On the platform body 201, there is a guide rail 204 for guiding the traction table 202. At the bottom of the traction table 202, there is a slider that matches the guide rail 204. The traction table 202 is slidably arranged on the platform body 201 through the guide rail 204. Through the cooperation of the guide rail 204 and the slider at the bottom of the traction table 202, the movement of the traction table 202 on the platform body 201 is guided and limited.

[0069] The traction drive mechanism includes a traction motor 207, a traction gear 208, and a traction rack 209 meshing with the traction gear 208. The traction motor 207 is arranged on the traction platform 202, the traction rack 209 is arranged on the platform body 201, and the traction gear 208 is arranged on the output shaft of the traction motor 207. When the traction motor 207 operates, the traction gear 208 rotates, and the meshing transmission between the traction gear 208 and the traction rack 209 realizes the movement of the battery module 6 on the platform body 201, thereby realizing the extraction and insertion of the battery into or from the vehicle or the battery compartment 3.

[0070] A plurality of auxiliary roller assemblies 210 for supporting the battery module 6 are arranged on the platform body 201. The auxiliary roller assembly 210 includes a roller frame and a plurality of rollers rotatably arranged on the roller frame, and the roller frame is arranged on the platform body 201. The friction of the battery module 6 on the platform body 201 is reduced, the movement of the battery module 6 on the platform body is smoother and easier, and the wear between the battery module 6 and the platform body 201 is small.

[0071] The battery compartment 3 includes a compartment body. A plurality of layers of storage positions 301 are arranged on the compartment body. Each layer is provided with a plurality of storage positions 301, and the plurality of storage positions 301 are arranged in a matrix. The open end of the storage position faces the battery swapping vehicle device. Each storage position 301 is provided with a support plate 302 and a positioning component. The positioning component includes a pair of oppositely arranged positioning guide plates 303. The pair of positioning guide plates 303 act on both sides of the battery module 6. The acting surface of the positioning guide plate 303 is a guiding inclined surface 304, and the pair of guiding inclined surfaces 304 are in a horn-shaped structure. The horn-shaped structure makes the entrance of the storage position 301 wide, facilitating the insertion of the battery module 6. As the battery module 6 is pushed in, the distance between the positioning guide plates 303 in the storage position 301 becomes narrower, realizing the position adjustment of the battery module 6, so that the battery end electrical connector 603 and the battery end water connector 604 of the battery module 6 can be correctly inserted and matched with the compartment end electrical connector 305 and the compartment end water connector 306 on the storage position 301, preparing for the charging and heat dissipation of the battery module 6 in the storage position 301.

[0072] A plurality of balls 308 for supporting the battery module 6 are arranged on the support plate 302. The balls 308 are used to assist the battery module 6 to enter and exit the storage position 301. Under the action of the balls 308, the battery module 6 enters and exits the storage position 301 with less friction, more smoothly and efficiently.

[0073] On the charging compartment 301, there are a compartment-end electrical connector 305 and a compartment-end water connector 306. When the battery module 6 is inserted in place in the compartment 301, the battery-end electrical connector 603 of the battery module 6 can be inserted and mated with the compartment-end electrical connector 305 to charge the battery module 6, and the battery-end water connector 604 of the battery module 6 can be hermetically docked with the compartment-end water connector 306 to cool and dissipate heat from the battery module 6.

[0074] The battery compartment 3 has multiple compartments 301. The functions of each compartment 301 can be reasonably planned according to the actual charging position requirements. Compartments 301 that can be used for charging can be planned. The compartments 301 for charging can not only charge the battery but also store the battery; compartments 301 for temporarily storing the battery module 6 can also be planned. In this way, while meeting the charging requirements, the number of charging facilities can be reduced, and the cost can be lowered. After the battery is fully charged in the charging compartment 301, it can be transferred to the storage compartment 301 for temporary storage waiting for battery swapping. When the battery module 6 is placed in the charging compartment 301, the battery is charged through the electrical connection between the compartment-end electrical connector 305 and the battery-end electrical connector 603 of the battery module 6.
