Description

Technical Field

[0001] The present application belongs to the technical field of electric vehicle battery replacement, and in particular relates to a water-electricity joint margin mechanism and an electric vehicle battery replacement system. Background Art

[0002] In existing battery charging systems, water-to-electricity connectors are often used to ensure a stable connection between the battery and the charging device. However, in practice, batteries of different types and sizes need to be connected to the same charging device, which places higher demands on the compatibility of the water-to-electricity connectors. Traditional systems often require additional palletizers or mobile adjustment racks to adjust according to battery size and position. This solution has several drawbacks:

[0003] Increased equipment complexity: Due to the need for a palletizer or mobile adjustment frame, the system's structural complexity increases, occupies a larger space, and increases the maintenance cost of the equipment.

[0004] Poor adaptability: If the battery type is frequently changed, the palletizer or mobile rack needs to be adjusted frequently, resulting in reduced charging efficiency and increased operating time.

[0005] High hardware dependence: The high reliance on mechanical structure reduces the stability of the system. Once the adjustment frame or palletizer fails, the charging operation will be seriously affected.

[0006] Therefore, how to achieve efficient position adjustment of water and electricity connectors and adapt to various sizes of batteries without relying on palletizers or mobile adjustment racks has become a major challenge facing existing technologies. Utility Model Content

[0007] In response to the shortcomings in the relevant technology, the utility model provides a water-electricity joint margin mechanism and an electric vehicle battery replacement system.

The mechanism comprises: a guide rail V installed on a battery rack column, a slider III installed on guide rail V, a guide rail VI installed on slider III via an upper and lower water-electric connector slide, guide rail VI being arranged horizontally, and the water-electric connector being installed on guide rail VI via slider IV. A driving mechanism drives the upper and lower water-electric connector slide or slider III to slide up and down along guide rail V; slider III is connected to a horizontally arranged cam positioning member, the other end of which is placed in a displacement groove of a water-electric connector displacement column via a pin shaft, the displacement groove comprising two connected grooves, the two grooves having different spacings from guide rail V, and the different spacings at the two ends corresponding to charging ports for two batteries of different sizes.

[0009] In a possible embodiment, a battery replacement system for an electric vehicle is also provided, comprising the above-mentioned water-electricity joint margin mechanism and a battery rack; the water-electricity joint margin mechanism is mounted on a column of the battery rack.

[0010] In one possible embodiment, multiple battery positioning devices are further included.

The battery positioning devices include large and small battery positioning shafts, which are respectively installed on the battery rack to accommodate large and small batteries of different sizes or specifications. The battery pads are installed on the battery rack, corresponding to the battery positioning devices, to support the batteries.

[0011] In one possible embodiment, the water-power connector margin mechanism further includes a proximity switch mounted on a column of the battery rack and a sensor plate mounted on upper and lower slides of the water-power connector. The sensor plate slides up and down along the guide rail V along with the upper and lower slides of the water-power connector. When the sensor plate contacts the proximity switch, the proximity switch is triggered, sending a signal to the control system.

[0012] In a possible implementation, the water and electricity connectors correspond to charging ports of the large battery or the small battery.

The locking and unlocking mechanism includes a Z-lock, a Y-lock, and an XY-lock, extending through the first deck. The Z-lock is mounted on an I-shaped Z-lift plate on the back of the first deck. An electric cylinder V is mounted on the back of the first deck via an electric cylinder mounting base. The output shaft of electric cylinder V is connected to the Z-lift plate, driving the Z-lift plate and its attached Z-lock up and down perpendicular to the plane of the first deck. Also mounted on the back of the first deck are electric cylinder III, guide rail III, electric cylinder IV, and guide rail IV. The output shaft of electric cylinder IV is connected to the XY-lock, which is connected to guide rail IV and can slide along guide rail IV under the push of electric cylinder IV. An electric cylinder VIII, a guide rail VIII and a Y-direction push plate are also installed on the back of a first layer of the plate. The Y-direction lock is connected to the guide rail VIII through the Y-direction push plate. The output shaft of the electric cylinder VIII is connected to the Y-direction push plate and pushes the Y-direction push plate and the Y-direction lock connected thereto to slide along the guide rail VIII.

[0015] Based on the above technical solution, the water-electric connector margin mechanism of the electric vehicle battery replacement system of the utility model realizes the adaptation and sliding adjustment of the water-electric connector between different battery charging ports by arranging a slider and a slide seat on the guide rail, and sliding the slide seat where the guide rail is located along the displacement groove, thereby solving the problem of matching battery charging interfaces of different sizes and improving the adaptability of the battery replacement system.

[0037] The following will be combined with the accompanying drawings in the examples of this application to clearly and completely describe the technical solutions in the embodiments. Obviously, the described embodiments are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0038] In the description of this application, it should be understood that the terms "center", "lateral", "longitudinal", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on this application.

[0039] The terms "first," "second," and "third" are used for descriptive purposes only and should not be understood to indicate or imply relative importance or to implicitly specify the quantity of the technical features indicated. Therefore, a feature specified as "first," "second," or "third" may explicitly or implicitly include one or more of such features.

[0040] In the description of this application, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to direct connections, indirect connections through an intermediate medium, or internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on the specific circumstances.

[0041] In order to solve the technical problems in the prior art caused by the diversity of battery sizes, such as low docking efficiency, complex operation and high maintenance costs, the present application provides a water-electricity joint margin mechanism and an electric vehicle battery replacement system.

[0042] See also Figure 1 、 Figure 12 and Figure 12a In one possible embodiment, the water-electricity connector margin mechanism 7 is installed between or on the layers of the battery rack 1, corresponding to the charging port of the battery on the battery rack 1. The water-electricity connector margin mechanism 7 includes a guide rail V 71 installed on the column of the battery rack 1, a slider III 72 installed on the guide rail V 71, and a guide rail VI 73 installed on the slider III 72 through the water-electricity connector upper and lower slides 74. The guide rail VI 73 is horizontally arranged, and the water-electricity connector 75 is installed on the guide rail VI 73 through the slider IV 76. The driving mechanism 77 drives the water-electricity connector upper and lower slides 74 or the slider III 72 to slide up and down along the guide rail V 71.

[0043] In the above embodiment, the water-electricity connector margin mechanism 7 achieves precise positioning of the water-electricity connector 75 via a guide rail system mounted on the column of the battery rack 1. The combined design of slider III 72, guide rail V 71, and guide rail VI 73 allows the water-electricity connector 75 to slide freely in both vertical and horizontal directions, thereby accurately docking with the battery charging port. The drive mechanism 77 achieves precise adjustment of the docking by controlling the movement of the water-electricity connector's upper and lower slide seat 74 or slider III 72.

[0044] This design effectively improves the efficiency and reliability of battery charging by precisely controlling the position of the water and electricity connector. The multi-directional sliding function of the water and electricity connector margin mechanism ensures a smooth docking process, reduces errors, and improves the degree of automation of the system.

[0045] See also Figure 12a and Figure 12b In a possible embodiment, the water-electricity joint margin mechanism 7 further includes: a proximity switch I 712, mounted on the column of the battery rack 1; a sensor plate I 713, mounted on the upper and lower slide seats 74 of the water-electricity joint, and sliding up and down along the guide rail V 71 with the slide seat.

[0046] When the sensing piece I 713 contacts the proximity switch I 712 , the proximity switch I 712 is triggered and sends a signal to the control system to confirm that the water and electricity connector 75 is aligned with the battery charging port.

[0047] Sensor piece I 713 moves along guide rail V 71 with water and electricity connector slide 74. When it reaches a predetermined position, sensor piece I 713 cooperates with proximity switch I 712 to trigger the control system to stop the sliding operation. This design ensures that the water and electricity connector 75 precisely mates with the battery charging port, avoiding docking errors.

[0048] In one possible embodiment, the electric vehicle battery replacement system further includes a water-electricity connector margin mechanism corresponding to the battery charging port, which is installed between or on the battery rack layers. The margin mechanism includes a guide rail V installed on the battery rack column, a slider III installed on the guide rail V, and a guide rail VI installed on the slider III via an upper and lower slide of the water-electricity connector. The guide rail VI is arranged horizontally, and the water-electricity connector is installed on the guide rail VI via the slider IV. The driving mechanism drives the upper and lower slides of the water-electricity connector or the slider III to slide up and down along the guide rail V. The slider III is connected to a horizontally arranged cam positioning member, and the other end of the cam positioning member is placed in the displacement groove of the water-electricity connector displacement column via a pin shaft. The displacement groove includes two connected grooves, and the spacing between the two connected grooves and the guide rail V is different. The different spacings of the two grooves correspond to the charging ports of two batteries of different sizes.

[0049] In the above embodiment, slider III is connected to a horizontally positioned cam locator. The drive mechanism operates slider III to slide up and down along guide rail V. As slider III moves, the cam locator, via a pin, pushes the water / electricity connector's displacement post within the displacement slot. The two interconnected sections of the displacement slot allow the water / electricity connector to automatically adjust its position based on battery size, achieving precise docking with the charging port of batteries of varying sizes.

[0050] This design, through the two-stage structure of the displacement slot, enables automatic adaptability of the water-to-electricity connector to batteries of varying sizes, significantly improving the system's versatility and compatibility. Regardless of battery size, the system precisely docks, eliminating the need for tedious manual adjustments and improving charging efficiency and safety.

[0052] The electric vehicle battery replacement system includes a battery rack 1 and multiple battery positioning devices. The battery rack 1 has a multi-layer structure, with battery positioning devices and battery pads 3 installed on each layer. The battery positioning devices consist of a large battery positioning shaft 21 and a small battery positioning shaft 22, respectively suitable for batteries 11 and 12 of different sizes or specifications. Battery positioning shafts 21 and 22 are mounted on the battery rack 1 to ensure stable installation and positioning of the batteries. Battery pads 3 are mounted on the battery rack 1 and are arranged in correspondence with the battery positioning devices to support the batteries and ensure their stability during use.

[0053] In the above embodiment, the multi-layered design of the battery rack 1 enables the system to accommodate multiple batteries, and different positioning devices are used to adapt to batteries of different sizes. The large battery positioning axis 21 and the small battery positioning axis 22 are adapted to the battery size, ensuring the stable fixation of the battery on the battery rack 1. The battery pad 3 cooperates with the battery positioning device to effectively support the battery, preventing it from shaking or shifting during use, and ensuring the safety and stability of the battery during operation of the electric vehicle.

[0054] This system design can accommodate batteries of various specifications, improving the convenience and adaptability of electric vehicle battery replacement. In addition, the support provided by the battery pad 3 further enhances the stability of battery installation, reduces damage to the battery due to vibration or impact, and extends the battery life.

[0055] See also Figure 2 and Figure 3 In one possible embodiment, the system further includes a palletizer 4, which is arranged in correspondence with the battery rack 1 and comprises a palletizer lift frame 41, an adjustment frame 42 mounted on the palletizer lift frame 41, a support fork 43, an electric cylinder I 441, a guide rail VII 45, and a support fork telescopic motor reducer assembly 46. The two support forks 43 are mounted on two adjustment frames 42, respectively, which are each mounted to the palletizer lift frame 41 via the guide rail VII 45. The support fork telescopic motor reducer assembly 46 and the push rod of the electric cylinder I 441 are connected to the two adjustment frames 42 via a push rod connecting block 443, respectively, to drive the two adjustment frames 42 toward or away from each other, adjusting the spacing between the two support forks 43. The electric cylinder I 441 is mounted on the palletizer lift frame 41 via an electric cylinder mounting base 442, and the push rod is connected to the adjustment frame 42 via the push rod connecting block 443.

[0056] The electric vehicle battery replacement system also includes a palletizer 4. The palletizer 4 is arranged corresponding to the battery rack 1, and specifically includes a palletizer lifting frame 41, an adjustment frame 42, a support fork 43, an electric cylinder I 44, a guide rail VII 45, and a support fork telescopic motor reducer assembly 46. Two support forks 43 are provided, which are installed on the adjustment frame 42, and the adjustment frame 42 is installed on the palletizer lifting frame 41 through the guide rail VII 45. The support fork telescopic motor reducer assembly 46 is installed on the adjustment frame 42 to drive the support fork 43 to extend and retract. The electric cylinder I 44 is connected to the adjustment frame 42 through the push rod connecting block 443, thereby driving the adjustment frame 42 to move horizontally to adjust the horizontal position of the two support forks 43. The electric cylinder I 44 is installed on the palletizer lifting frame 41 through the electric cylinder mounting seat 442, and the push rod is connected to the adjustment frame 42 through the push rod connecting block 443 to achieve position adjustment of the support fork 43.

[0057] In the above embodiment, the palletizer 4, via its lifting frame 41, is able to flexibly move between different heights of the battery rack 1. The electric cylinder I 441, via a push rod connecting block 443, pushes the adjustment frame 42 to adjust the horizontal position of the fork. The fork telescopic motor-reducer assembly 46, mounted on the adjustment frame 42, drives the fork 43 to extend and retract, adjusting the distance the fork extends. The structural arrangement of the electric cylinder I 441, the fork telescopic motor-reducer assembly 46, the adjustment frame 42, and the fork 43 enables the system to precisely adjust the position and extension distance of the fork to accommodate batteries or battery packs of varying sizes.

[0058] The flexibility and precision of this palletizer system significantly improves battery replacement efficiency. By adjusting the spacing between the pallet forks, it can quickly adapt to batteries of different sizes, reducing the need for manual intervention and the risk of misoperation when installing or removing batteries.

[0059] In a possible embodiment, the palletizer 4 further includes a palletizer bracket 47, and the palletizer lifting frame 41 is installed on the palletizer bracket 47 through a palletizer lifting mechanism, and the palletizer lifting mechanism drives the palletizer lifting frame 41 to move up and down along the palletizer bracket 47. Figure 4 and Figure 5 The anti-fall device 49 is mounted on the palletizer lifting frame 41 via the anti-fall device mounting base 491. The anti-fall guide rail 492 is mounted on the column of the palletizer bracket 47, extending along the column in the same direction of movement as the palletizer lifting frame 41. When the palletizer lifting frame 41 reaches the set lower position, the gap in the anti-fall device 49 clamps the anti-fall guide rail 492, preventing the palletizer lifting frame 41 from falling.

[0060] In the above embodiment, the palletizer lifting frame 41 can be freely adjusted to different heights through the palletizer lifting mechanism, ensuring convenient and accurate battery replacement. The anti-fall device 49 is designed to automatically lock when the lifting frame 41 reaches the set position, preventing accidental falls and thus ensuring safe operation.

[0061] The system's anti-fall device effectively prevents the lifting frame from accidentally falling, ensuring operator safety. Furthermore, precise control of the lifting mechanism enables the Palletizer 4 to efficiently replace batteries in a variety of complex scenarios.

[0062] See also Figure 1 and Figure 6-9aThe electric vehicle battery replacement system also includes a locking and unlocking mechanism 6, which is arranged on the battery tray 56. The battery tray 56 includes a first layer plate 61 and a second layer frame 62, and the first layer plate 61 is installed above the second layer frame 62; the locking and unlocking mechanism 6 includes a Z-direction lock head 63, a Y-direction lock head 64 and an XY-direction lock head 65 passing through the first layer plate 61; wherein the Z-direction lock head 63 is installed on the second layer frame 62 on the back of the first layer plate 61 through an I-shaped Z-direction lifting plate 66, and an electric cylinder V 67 is installed on the back of the first layer plate 61 or on the second layer frame 62. The output shaft of the electric cylinder V 67 is connected to the Z-direction lifting plate 66, driving the Z-direction lifting plate 66 and the Z-direction lock head 63 thereon to move up and down in a direction perpendicular to the plane of the first layer plate 61; a guide shaft 68 is provided on the Z-direction lifting plate 66, which passes through the first layer plate 61, and the Z-direction lifting plate 66 and the Z-direction lock head 63 thereon move along the guide shaft 68 Move up and down; an electric cylinder III 69, a guide rail III 610, an electric cylinder IV 611 and a guide rail IV 612 are arranged on the back of a layer of plate 61.

The output shaft of the electric cylinder Ⅷ613 is connected to the Y-direction push plate 615 and can push the Y-direction push plate 615 and the Y-direction lock head 64 connected to it to slide along the guide rail Ⅷ614.

[0063] The locking and unlocking mechanism 6 automatically locks and unlocks the battery tray 56 through locks in three directions (Z, Y, and XY) and their corresponding electric cylinders and guide rail systems. The Z-direction lock 63 moves up and down along the guide shaft 68 via electric cylinder V 67, ensuring that the battery tray 56 is locked or released in the vertical direction. The Y-direction lock 64 and the XY-direction lock 65, respectively, are pushed by electric cylinders VIII 613 and IV 611, sliding on the corresponding guide rails VIII 614 and IV 612 to lock or release the battery tray 56 in the Y and XY directions. This multi-directional locking and unlocking design allows the battery tray 56 to be securely fixed in three dimensions, ensuring the safety and stability of the battery during replacement.

[0064] The locking and unlocking mechanism provides multi-directional locking methods, ensuring the safety and reliability of the battery during installation and replacement. The multi-directional locking design not only enhances the battery's secure retention, but also improves the operating efficiency of the entire system.

[0065] In one possible embodiment, there are four Z-direction locks 63, which are respectively arranged at the four ends of the I-shaped Z-direction lifting plate 66. The first layer plate 61 and the second layer frame 62 are connected by adsorption via electromagnets 616, and four electromagnets 616 are provided.

[0066] In the above embodiment, there are four Z-locking heads 63, positioned at the four I-shaped endpoints of the Z-lift plate 66, ensuring multiple locking points for the battery and enhancing stability. Electromagnets 616 provide additional suction force, tightly connecting the first-layer plate 61 and the second-layer frame 62 via electromagnetic attraction, further enhancing the stability and safety of the overall structure.

[0067] This design effectively improves the system's securement performance and operational safety by increasing the number of Z-axis locks 63 and introducing electromagnetic adsorption. This design provides a more stable and reliable battery fixation, especially in applications requiring higher strength and reliability.

[0068] See also Figure 6 In one possible embodiment, a side scissor assembly is provided between the first deck 61 and the second deck 62. The assembly includes two side scissor forks 617, two fixed seats 618, two sliding seats 619, and two guide rails 620. The two side scissor forks 617 are arranged in an X-shape and are fixed to the first deck 61 and the second deck 62 via fixed seats 618, respectively. The other ends of the side scissor forks 617 are connected to the guide rails 620 via sliding seats 619. The guide rails 620 are installed on the first deck 61 and the second deck 62.

[0069] The side scissor assembly, through its X-shaped structure, provides additional support and adjustment for the first-layer panel 61 and second-layer frame 62. During the installation and removal of the battery's first-layer panel, the side scissor assembly withstands the panel's weight and guides its smooth movement. By sliding the slide 619 on the guide rail 620, the side scissor assembly allows for flexible adjustment of the first-layer panel, ensuring stability and precise positioning during battery replacement.

[0070] In another embodiment, the number and size of the side scissor fork assemblies can be adjusted according to the weight and size of a battery layer. The design of the guide rail 620 and the sliding seat 619 can also be optimized as needed, and more durable or corrosion-resistant materials can be selected to adapt to applications in harsh environments.

[0071] In one possible embodiment, two sets of side scissor fork assemblies are provided, one set parallel to the other on opposite sides of the first layer plate 61 and the other set parallel to the second layer frame 62. These two sets of side scissor fork assemblies can provide support and adjustment functions for the battery tray at different positions, thereby achieving stable movement and locking of the first layer battery tray.

[0072] Two sets of side scissor forks are installed on opposite sides of the battery tray. This parallel arrangement further increases the tray's stability and load-bearing capacity. During the battery replacement process, the side scissor forks not only support the tray but also adjust its height and position vertically and horizontally to ensure that the first battery tray can be locked or unlocked smoothly.

[0073] In one possible embodiment, the two side scissor forks 617 are connected at the X-shaped center by a pin II 621. The pin 621 enables the side scissor forks 617 to be flexibly extended and adjusted through the rotation function of its center point, thereby enhancing the mobility of the support plate.

[0074] The X-shaped structure of the side scissor forks 617 is connected by a pin 621, allowing the side scissors to rotate about the pin, providing stable adjustment of the first deck in the vertical direction. During the battery replacement process, when the first deck moves up and down, the pin 621 allows the side scissor forks to automatically adjust to the height change of the first deck, maintaining the balance and stability of the first deck.

[0075] See also Figure 7 In one possible embodiment, the locking and unlocking mechanism further includes a drag chain 622, disposed between the first deck 61 and the second deck 62, for routing cables for the motor and switchgear. Drag chain 622 includes a channel 623, through which the cables are routed and protected, ensuring their safety and reliability during movement within the first deck.

[0076] The flexible design of the drag chain 622 connects the first-layer panel 61 and the second-layer frame 62. The channels 623 accommodate the cables for the motor and switchgear. As the battery's first-layer panel moves, the drag chain 622 expands and contracts with the panel, ensuring that the cables are not damaged or broken by the movement of the first-layer panel. Furthermore, the channels 623 provide excellent cable protection, preventing damage from the external environment.

[0077] In one possible embodiment, a method for charging electric vehicle batteries of different specifications is provided, using any of the electric vehicle replacement battery systems. The method comprises the following steps:

[0078] Control the feeding battery to move between or on the layers of the battery rack, and control the large battery positioning axis or the small battery positioning axis to position the feeding battery according to the model of the feeding battery.

[0079] Control the Z-axis lock, Y-axis lock and XY-axis lock to lock the feed battery.

[0080] According to the model of the feeding battery, the driving mechanism is controlled to drive the slider III or the upper and lower slide seats of the water-electricity connector to keep it stationary or move it downward, so that the water-electricity connector is docked with the charging port of the feeding battery.

[0081] This battery replacement method is based on the above-mentioned electric vehicle battery replacement system and includes the following steps:

[0082] Control the movement of the feed battery:

[0083] The system moves the battery that needs to be replaced to the middle or upper layer of the battery rack. The control system identifies the different battery models.

[0084] Battery positioning and locking:

[0085] Depending on the type of feed battery, the system controls the large battery positioning axis 21 or the small battery positioning axis 22 to adapt the battery to its position, ensuring that the battery is accurately positioned. After positioning, the Z-axis lock 63, Y-axis lock 64, and XY-axis lock 65 sequentially lock the feed battery, achieving multi-directional battery fixation.

[0086] Slide docking charging port:

[0087] According to the battery model and the location requirements of the charging port, the driving mechanism 77 drives the slider III 72 or the water and electricity connector upper and lower slide 74 to move to the appropriate position along the guide rail V 71. After the sliding is completed, the water and electricity connector 75 is accurately docked with the battery charging port.

[0088] Charging status detection and feedback:

[0089] When the water and electricity connector 75 is successfully connected to the battery charging port, the sensor piece I 713 contacts the proximity switch I 712 as the slide 74 slides, triggering the control system to send a signal to confirm the connection status. At this time, the system can start charging or replacing the feed battery based on the feedback information.

[0090] This method achieves precise positioning and charging docking of batteries of different specifications through automated control, effectively reducing manual operation errors and time, improving charging efficiency and the intelligence of the system. Furthermore, the multi-directional locking design ensures the safety of the charging process and reduces the risk of charging failures caused by vibration or unstable connections.

[0091] Other embodiments of the present invention are as follows:

[0092] 1. Battery rack

[0093] 1. The battery rack is equipped with two battery positioning devices. The position of different batteries is adjusted by the stacker, so that the batteries are placed on two positioning shafts. The positioning shafts are installed on the battery rack by screws, so that the battery rack can be compatible with both large and small batteries and can charge the batteries. Figure 1 .

[0094] 2. Palletizer

[0095] 1. The palletizer's fork is equipped with a fork displacement mechanism. During the lifting process of the fork, the electric cylinder pushes the fork on the adjustment frame to achieve displacement adjustment of the fork perpendicular to the extension direction and the vertical direction. The entire extension mechanism of the two forks is placed on the adjustment frame, and the electric cylinder pushes the adjustment frame to ensure that the distance between the forks remains unchanged while achieving short-distance movement. Figure 2 and Figure 3 By adjusting the rack displacement, the two types of batteries are placed so that their charging ports are in the same position. Differentiate the V.1 water and electricity connector margin mechanism. This solution is to adapt the mobile battery to the fixed water and electricity connector position.

[0096] 2. The palletizer lifting mechanism has a new anti-fall device to prevent it from falling. By installing an anti-fall guide rail on the palletizer column and placing the anti-fall guide rail in the middle gap of the anti-fall device, if the lifting mechanism fails and falls due to a synchronous belt break or other reasons, the anti-fall device will clamp the anti-fall guide rail to prevent the lifting frame from falling, thereby improving the operation safety and emergency handling capabilities of the palletizer. Figure 4 Figure 5 .

[0097] 3. Lock and unlock mechanism

[0098] 1. The locking and unlocking mechanism can adapt to two types of batteries of different sizes. The locking and unlocking lock head is pushed by the electric cylinder to realize the locking and unlocking operation for two types of batteries. When removing and installing a small battery, the locking and unlocking connector moves inward under the push of the electric cylinder. When removing and installing a large battery, the locking and unlocking connector moves to the outer edge. Figure 8 The back of the unlocking layer is equipped with an electric cylinder to drive the guide rail slider mechanism, which is connected to the unlocking lock head through the push plate. It is suitable for loading and unloading two types of batteries, large and small. At the same time, four electromagnets are arranged to ensure that the unlocking top layer will not deviate during operation. Figure 9 At the same time, in order to realize the removal and installation of large batteries, the two corner locks move in the "L" direction (XY direction), and two layers of electric cylinders are arranged to push and control their movement in two directions and reach the specified position. Figure 10 .

[0099] When locking and unlocking the lock, the lock moves to a position suitable for the corresponding battery and is lifted by the electric cylinder. The four middle locks are lifted at the same time by the electric cylinder connected to the Z-direction lifting plate, saving internal space for locking and unlocking. Then the 12 locks perform the locking and unlocking operation.

[0100] 2. The four locking and unlocking heads are connected through an "I"-shaped Z-direction lifting plate. The Z-direction lifting plate determines the Z-direction movement direction through two guide shafts and is connected to the top plate through the electric cylinder and the electric cylinder mounting base. The electric cylinder is used to realize the lifting of the four locking and unlocking heads. Figure 11 .

[0101] 4. Margin mechanism of water and electricity joint

[0102] 1. The water and electricity joints are equipped with a margin mechanism. Figure 12 and Figure 12a When charging, by controlling the falling distance of the water and electricity connector and the extending distance of the water and electricity connector, it can be used to charge two batteries placed on the battery rack. This solution is applicable to the case 2.1 where the mobile adjustment rack of the palletizer is not included, and the position of the water and electricity connector is moved to adapt to the two sizes of batteries.

[0103] As another implementation method, the battery swapping process and mechanism at the battery swapping station are described as follows;

[0104] The utility model provides a battery swapping station system for reducing the occupied volume of the battery swapping station without reducing the battery swapping time. The existing technologies include:

[0105] 1. The battery swap station sets up a cache position for placing the removed batteries. After the feed battery removed from the vehicle is placed in the cache position, the fully charged battery is moved from the docking position to the RGV, and then the fully charged battery is installed on the vehicle. It is best to move the cache position battery to the battery compartment.

[0106] Disadvantages of existing technology 1: The cache space temporarily takes up more space, and the box of the battery swap station also needs to be larger;

[0107] 2. Cancel the docking position, put the checked battery into the battery compartment, and then move a new battery to the RGV;

[0108] Disadvantages of existing technology 2: The battery replacement time is too long. After the battery on the car is disassembled, it needs to be sent to the battery warehouse first, and then another battery is transported, which adds more time and is not a good experience for customers.

[0109] This utility model describes a battery replacement process and mechanism, which eliminates the cache position, reduces the area occupied by the battery replacement station and the size of the box, and adopts a double-layer design from the docking position to the RGV conveying mechanism. Before the battery replacement, a fully charged battery is prepared on the lower layer, and the removed feeding battery is moved from the RGV to the upper layer. The feeding battery is transported from the upper layer to the docking position, and the fully charged battery is transported from the lower layer to the RGV.

[0110] A1 and A2, B1 and B2 are two groups of battery lifting mechanisms, with upper and lower layers, which reciprocate left and right on the slide rails through belts;

[0111] A1 and A2 are responsible for transporting the dismantled old batteries, while B1 and B2 are responsible for transporting the fully charged new batteries to be installed.

[0112] First, place the fully charged new battery on B1B2, move A1 and A2 to the removed feed battery, lift the battery, then move A1A2 to the right and B1B2 to the left synchronously; the two sets of lifting mechanisms move synchronously to reduce the transportation time; after the battery replacement is completed, move the A1A2 battery to the battery rack, A1A2 to the left, and B1B2 to the right to return to the starting point.

[0113] 1. This solution adopts a two-layer conveying mechanism design, which reduces the number of cache positions without reducing the battery replacement speed, reducing the cost of the battery replacement station while retaining the battery replacement experience; it adopts a double-layer conveying mechanism, which is in the form of a battery replacement cart instead of a double-layer conveyor belt; it adopts a lifting and moving method to transport batteries.

[0114] Finally, it should be noted that the various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.

[0115] The above embodiments are only used to illustrate the technical solutions of the present application and are not intended to limit the same. Although the present application has been described in detail with reference to the preferred embodiments, ordinary technicians in the relevant field should understand that the specific implementation methods of the present application can still be modified or some technical features can be replaced by equivalents without departing from the spirit of the technical solutions of the present application. They should all be included in the scope of the technical solutions for which protection is requested in the present application.
