Description

Technical Field

[0001] The present invention relates to the field of battery replacement for electric vehicles, and in particular to a battery replacement device for electric vehicles. Background Art

[0002] In the prior art, the power supply methods of electric vehicle power batteries are generally divided into two methods: plug-in charging with the vehicle and replacing the battery. The plug-in charging method has two modes: slow charging and fast charging. The plug-in charging method has the following defects: 1. The initial investment cost of the battery is relatively large, which to a certain extent hinders the popularization of electric vehicles; 2. The charging time is too long, at least 2 to 4 hours. Compared with refueling of ordinary cars, the time spent on replenishing energy for electric vehicles is too long, which is very inconvenient and far from meeting people's needs. The fast charging mode will cause greater damage to the battery, resulting in a shortened battery life.

[0003] The battery replacement method can effectively avoid the problems of the plug-in charging method. However, due to the height restrictions of the vehicle and the location of the battery pack, the battery pack replacement requires the use of a battery replacement platform to achieve rapid battery replacement. The existing battery replacement platform has the following technical problems:

[0004] 1) The battery swapping compartments of battery swapping stations on the market are much higher than the ground, resulting in a large uphill slope and poor visibility for vehicles entering, affecting the driving experience;

[0005] 2) During the battery swap process, since the vehicle is located at a high altitude, the driver and passengers cannot leave the vehicle smoothly when a dangerous situation occurs at the battery swap station or the vehicle;

[0006] 3) When transporting batteries, due to insufficient transport space, the equipment must use complex structures to avoid the batteries in order to solve the battery transportation problem.

[0007] Therefore, it is necessary to provide a battery replacement platform that is easy to drive into and can replace batteries safely and smoothly to solve the above technical problems. Summary of the invention

[0008] In order to solve the above technical problems, the present invention provides an electric vehicle battery replacement device, which solves the technical problems in the prior art that the electric vehicle battery replacement process is dangerous, the driver and passengers cannot get off the vehicle safely, and the vehicle is inconvenient to replace the battery.

[0009] The technical effects of the present invention are achieved as follows:

[0010] A battery replacement device for electric vehicles, including a battery replacement platform component and a lifting component; the battery replacement platform component includes a vehicle guide plate, a transition plate, a lifting plate and a battery support plate, the transition plate is arranged between the lifting plate and the guide plate and one end is smoothly connected to the vehicle guide plate, and the lifting plate is arranged horizontally; the lifting component includes a driving mechanism and a lifting mechanism, the lifting mechanism includes a lifting part and a lifting plate connecting part, the lifting part is used to contact with the vehicle lifting point to lift the vehicle, and the lifting plate connecting part is used to lift the lifting plate from a first height to a second height during the vehicle lifting process; when the lifting plate is at the first height, the other end of the transition plate is smoothly connected to the lifting plate. By setting the lifting plate, even if the vehicle is lifted to the highest point during the battery replacement process, when encountering problems, the driver and passengers can get on and off the lifting plate at the same height as the bottom of the vehicle, and then leave from the steps formed by the lifting plate and the transition platform.

[0011] Furthermore, the lifting plate connecting part is a lifting arm arranged below the lifting plate, one end of the lifting arm is connected to a driving mechanism, and the other end of the lifting arm is connected to the lifting part. The lifting plate is provided with a yield structure corresponding to the lifting part, and when the vehicle is lifted, the lifting part passes through the yield structure and contacts the lifting point of the vehicle.

[0012] Furthermore, the lifting arm is provided with a plurality of positioning pins, and the lower surface of the lifting plate is provided with positioning holes matching the positioning pins, and the cooperation between the positioning pins and the positioning holes effectively prevents the lifting plate from moving in the horizontal direction.

[0013] Furthermore, it also includes a support block arranged on the base, and when the lifting mechanism is at the bottom dead point, the upper surface of the support block abuts against the lifting plate and the upper surface of the lifting plate is higher than the upper surface of the lifting part. Such a configuration ensures that when a vehicle passes by, it will not directly press on the lifting part, thus avoiding deformation of the lifting arm caused by frequent downward pressure of the vehicle tire.

[0014] Furthermore, a deformable blocking member is provided between the lifting plate and the transition plate, one end of the blocking member is connected to the lifting plate, and the other end of the blocking member is lower than the transition plate. The blocking member can be made of elastic material or a folding accordion plate, etc. When the lifting plate and the transition plate form a step, the blocking member blocks the gap formed by the two, and when the driver and passengers need to step from the lifting plate to the transition plate, they can effectively prevent stepping into the gap due to mistakes.

[0015] Furthermore, a limiting mechanism for limiting the area where vehicles enter is provided on the lifting plate.

[0016] Furthermore, there are two lifting assemblies respectively arranged on both sides of the battery exchange platform assembly, there are two lifting plates respectively connected to the lifting plate connecting parts of the two lifting assemblies, and a battery lifting platform assembly is provided between the two lifting plates.

[0017] Furthermore, a battery transfer assembly is provided under the battery exchange platform assembly.

[0018] Furthermore, the battery lifting platform includes a battery lifting plate and a battery plate lifting mechanism.

[0019] Furthermore, the battery transport assembly includes a plurality of roller assemblies, and the battery lifting tray is provided with an opening matching one of the roller assemblies.

[0020] As described above, the present invention has the following beneficial effects:

[0021] 1) By setting up a lifting platform, even if the vehicle is lifted to the highest point during the battery replacement process, if there is a problem, the driver and passengers can get on and off the vehicle from the lifting platform at the same height as the bottom of the vehicle, and then leave from the steps formed by the lifting platform and the transition platform, ensuring the safety of the battery replacement process;

[0022] 2) By providing the support blocks, the vehicle will not directly press on the lifting part when passing by, thus avoiding deformation of the lifting arm caused by frequent downward pressure of the vehicle tires.

[0023] 3) A deformable blocking member is provided, which blocks the gap formed by the lifting plate and the transition plate when the lifting plate and the transition plate form a step, thereby effectively preventing the driver and passengers from stepping into the gap by mistake when they can only get off the vehicle during the battery replacement process.

[0024] 4) The battery lifting platform and battery transport assembly can easily replace the battery, and the height formed by the lifting mechanism allows enough space to transport the battery. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0034] 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 only 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 making creative work are within the scope of protection of the present invention.

[0035] Embodiment 1:

[0036] like Figure 1-6As shown, an electric vehicle battery replacement device includes a battery replacement platform component 1 and a lifting component 2; the battery replacement platform component 1 is designed for vehicles to enter and park, and the lifting component 2 is used to control the lifting of the vehicle. The battery replacement platform component 1 includes a vehicle guide plate 11, a transition plate 12 and a lifting plate 13, the transition plate 12 is arranged between the lifting plate 13 and the guide plate 11 and one end is smoothly connected to the vehicle guide plate 12, and the lifting plate 13 is arranged horizontally; the lifting component 2 includes a driving mechanism 21 and a lifting mechanism 22, the lifting mechanism 22 includes a lifting part 221 and a lifting plate connecting part 222, the lifting part 221 is used to contact with the vehicle lifting point to lift the vehicle, and the lifting plate connecting part 222 is used to lift the lifting plate from a first height to a second height during the process of lifting the vehicle; the first height corresponds to the lower dead point position of the lifting component 2, and the second height corresponds to the upper dead point position of the lifting component. When the lifting plate 13 is at the first height, the other end of the transition plate 12 is smoothly connected to the lifting plate 13. The vehicle guide plate 11 is at a certain angle to the ground, and the angle is as small as possible to ensure that the driver's blind spot is effectively reduced, and the user experience is more stable. The optional range is 3-15°, preferably 5° and 10°. Due to the presence of the lifting assembly 2, the vehicle guide plate 11 does not need to be set to a large angle like a traditional battery exchange platform, which is more convenient for the vehicle to enter. In the embodiment of the present application, the car passes through the transition plate 12 through the guide plate 11 and enters the area of ​​the lifting plate 13. The lifting point of the vehicle (such as the tire) is aligned with the lifting part 221, so that the vehicle can be driven up when the lifting part 221 rises. The lifting plate 13 rises synchronously with the lifting plate connecting part 222 during the lifting process, so that during the battery exchange process, there is a plate outside the car that rises and falls synchronously with the vehicle, so that in the event of an accident, the passenger can directly step on the lifting plate 13 to leave the vehicle, and walk down the steps formed by the lifting plate 13 and the transition plate 12.

[0037] Furthermore, the lifting plate connection part 222 is a lifting arm provided below the lifting plate, one end of the lifting arm is connected to the driving mechanism, and the other end of the lifting arm is connected to the lifting part 221. The lifting plate 13 is provided with a yielding structure 131 corresponding to the lifting part, and when the vehicle is lifted, the lifting part passes through the yielding structure and contacts the vehicle lifting point. The yielding structure in this embodiment is specifically a yielding groove, which can ensure that the lifting part 221 does not affect the contact with the vehicle when the area of ​​the lifting plate 13 is as large as possible. The lifting part 221 is specifically a lifting block connected to the lifting arm, and the upper surface height is higher than the upper surface of the lifting arm.

[0038] Furthermore, the lifting arm is provided with a plurality of positioning pins 223, and the lower surface of the lifting plate 13 is provided with positioning holes 132 matching the positioning pins 223. The cooperation between the positioning pins and the positioning holes effectively prevents the lifting plate from moving in the horizontal direction.

[0039] In addition, the present embodiment further includes a support block 3 disposed on the base, and when the lifting mechanism is at the bottom dead point, the upper surface of the support block 3 abuts against the lifting plate 13, and the upper surface of the lifting plate 13 is higher than the upper surface of the lifting portion 221. This prevents vehicles from directly pressing on the lifting portion when passing by, thus avoiding deformation of the lifting arm caused by frequent downward pressure of vehicle tires.

[0040] Furthermore, a deformable blocking member 14 is provided between the lifting plate 13 and the transition plate 12, one end of the blocking member 14 is connected to the lifting plate 13, and the other end of the blocking member 13 is lower than the transition plate 12. In this embodiment, the blocking member is a folding accordion plate, which blocks the gap formed by the lifting plate and the transition plate when the lifting plate and the transition plate form a step, and can effectively prevent the driver and passengers from stepping into the gap due to mistakes when they can only get off the vehicle during the battery replacement process.

[0041] The lifting plate 13 is provided with a limiting mechanism 133 for limiting the area where vehicles enter, and the limiting mechanism is specifically a limiting rod provided on the lifting plate 13, and the width between the limiting rods is greater than the width of the vehicle. It can also be a limiting mechanism such as a limiting block.

[0042] Furthermore, there are two lifting assemblies 2, which are respectively arranged on both sides of the battery exchange platform assembly 1, and there are two lifting plates 13, which are respectively connected to the lifting plate connecting parts 222 of the two lifting assemblies 2, and a battery lifting platform assembly 4 is arranged between the two lifting plates 13. By symmetrically arranging two sets of lifting assemblies, the lifting process is more stable.

[0043] Furthermore, a battery transfer assembly 5 is provided below the battery exchange platform assembly 1. The battery lifting platform includes a battery lifting tray 41 and a battery tray lifting mechanism. The battery transfer assembly 5 includes a plurality of roller assemblies 51, and an opening 42 matching one of the roller assemblies 51 is provided on the battery lifting tray 41. In this embodiment, there are three groups of roller assemblies, which are respectively arranged below the opening 42 and on both sides of the battery exchange platform assembly 1.

[0044] Battery replacement process: the vehicle passes through the guide plate 11 and enters the lifting plate 13 area, the wheels are aligned with the lifting part 221, the lifting part 221 passes through the yielding structure 131 and contacts the vehicle tires, and while the lifting drives the vehicle to rise, the lifting plate 13 rises synchronously, and the battery lifting tray 41 is also driven to the battery replacement position at the bottom of the vehicle under the drive of the battery tray lifting mechanism, the exhausted battery is removed and lowered, and the battery contacts the roller assembly through the opening 42 to transport the battery, and cooperates with the other roller assemblies to transport the battery through the space formed after lifting. In the next step, the fully charged battery is reversed by the roller and installed on the battery lifting tray.

[0045] Embodiment 2:

[0046] In this embodiment, the battery lifting tray 41 does not have an opening, and the roller assembly has 23 groups, which are respectively arranged on both sides of the battery replacement platform assembly 1. After the battery is removed, the battery lifting tray is lowered and pushed to the roller assembly on the side for transportation by manpower.

[0047] As described above, the present invention has the following beneficial effects:

[0048] 1) By setting up a lifting platform, even if the vehicle is lifted to the highest point during the battery replacement process, if there is a problem, the driver and passengers can get on and off the vehicle from the lifting platform at the same height as the bottom of the vehicle, and then leave from the steps formed by the lifting platform and the transition platform, ensuring the safety of the battery replacement process;

[0049] 2) By providing the support blocks, the vehicle will not directly press on the lifting part when passing by, thus avoiding deformation of the lifting arm caused by frequent downward pressure of the vehicle tires.

[0050] 3) A deformable blocking member is provided, which blocks the gap formed by the lifting plate and the transition plate when the lifting plate and the transition plate form a step, thereby effectively preventing the driver and passengers from stepping into the gap by mistake when they can only get off the vehicle during the battery replacement process.

[0051] 4) The battery lifting platform and battery transport assembly can easily replace the battery, and the height formed by the lifting mechanism allows enough space to transport the battery.

[0052] In this document, the directional words such as front, back, top, and bottom are defined by the positions of the components in the drawings and the positions of the components relative to each other, and are only for the sake of clarity and convenience in expressing the technical solution. It should be understood that the use of the directional words should not limit the scope of protection claimed in this application.

[0053] In the absence of conflict, the above embodiments and features in the embodiments can be combined with each other.

[0054] The above disclosure is only a preferred embodiment of the present invention, which certainly cannot be used to limit the scope of the present invention. Therefore, equivalent changes made according to the claims of the present invention are still within the scope of the present invention.
