Description

Technical Field

[0001] This invention belongs to the field of non-road engineering machinery technology, specifically relating to an electric new energy stacker with a quick battery swapping capability and a method for quickly loading and unloading batteries. Background Technology

[0002] Forklifts are specialized engineering machinery used for stacking and handling empty containers. They offer advantages such as high stacking and transfer efficiency, safety and reliability, and low operating costs, and are widely used in container yards, ports, and docks. Due to national and international environmental protection policies, the demand for traditional internal combustion engine equipment is gradually decreasing, while the demand for pure electric new energy equipment is increasing. Electric products have many advantages, but they still have some shortcomings.

[0003] like Figure 1 As shown, this is a non-battery-swapping forklift. The battery, high-voltage box, and radiator are fixed to the chassis via brackets, forming a single, non-removable unit covered by exterior components. Because the battery is non-removable, the forklift can only be powered by charging. Furthermore, the battery requires a capacity of 350 kWh, meaning a charging time of up to 1.25 hours, preventing uninterrupted operation. For long-term operation, two forklifts are needed, increasing stacking and transport costs and requiring more operators. Summary of the Invention

[0004] This invention provides an electric new energy forklift with a quick battery swapping capability and a method for quickly loading and unloading batteries, solving the problems of existing forklifts that cannot have their batteries swapped and cannot operate for extended periods.

[0007] The frame base is L-shaped, with its long side fixedly connected to the frame and the battery pack installed on the short side;

[0008] The battery pack is used to provide power to the forklift. The battery pack is an independent power supply unit and includes a frame, battery pack, high voltage box, charging port, battery swapping docking female plug, and battery heat sink.

[0009] The bottom surface of the frame is adapted to the short side of the chassis support;

[0010] The battery pack is housed within the frame.

[0011] The high-voltage box is connected to the battery pack and is located above the battery pack. The high-voltage box is set inside the frame and has a charging port and a battery swapping female plug.

[0012] The battery heat sink is connected to the battery pack and is located above the battery pack. The battery heat sink is inside the frame and provides liquid cooling for the battery pack.

[0013] The locking push rod mechanism is located on the short side of the chassis base, and the output end of the locking push rod mechanism is equipped with a battery swapping connector.

[0014] The battery swapping male connector is connected to the forklift's main unit via a ribbon cable;

[0015] When the battery pack is placed on the chassis support, the locking push rod mechanism pushes the male battery swapping connector to move, so that the male battery swapping connector connects with the female battery swapping connector.

[0016] As a further preferred embodiment of the present invention, it further includes at least two positioning pins and at least two positioning pin holes. The positioning pins are disposed on the short side of the frame base, and the positioning pin holes are opened at the bottom of the frame. The number of positioning pins is the same as the number of positioning pin holes. When each positioning pin is engaged with a positioning pin hole, the battery pack is positioned at a suitable position on the frame base.

[0017] As a further preferred embodiment of the present invention, it further includes a locking push rod mounting base, a locking push rod, a side pin, and a guide seat, wherein:

[0018] The locking push rod mounting seat is located on the short side of the chassis base;

[0019] The locking push rod is mounted on the locking push rod mounting base;

[0020] One end of the side pin is connected to the locking push rod, and the other end extends into the external environment;

[0021] The guide seat is positioned in the direction of the side pin extension, and the side pin passes through the guide seat when it moves to its maximum limit position as the locking push rod moves.

[0022] As a further preferred embodiment of the present invention, the locking push rod, the locking push rod mounting seat, the guide seat, and the side pin constitute a limiting mechanism. There are four limiting mechanisms, which are distributed around the short side of the chassis base. The locking push rods of the two diagonally opposite limiting mechanisms extend in opposite directions, and the locking push rods of the two limiting mechanisms on the same side extend in perpendicular directions.

[0023] As a further preferred embodiment of the present invention, each guide seat is disposed at the inner edge of the frame of the short side of the chassis base; when the battery pack is installed at a suitable position on the chassis base, the side of each guide seat opposite to the locking push rod mounting seat is in contact with the frame of the battery pack.

One end of the electric telescopic rod is mounted on the electric telescopic rod mounting base, and the other end of the electric telescopic rod is fixed to the battery swapping connector.

[0026] As a further preferred embodiment of the invention, it also includes two fork-mounting holes, which are disposed at the bottom of the frame.

[0027] A method for quickly loading and unloading batteries is also provided. This method utilizes the aforementioned forklift to perform the operation of quickly loading and unloading batteries, specifically including the following two methods for quickly loading and unloading batteries:

[0028] The first method for quickly installing and removing batteries:

[0029] Step A: Battery Pack Installation

[0030] Step A1: Use a forklift to move the fully charged battery pack to the vicinity of the forklift's chassis support;

[0031] Step A2: The operator operates the forklift to align the positioning pin hole on the battery pack frame with the positioning pin on the short side of the chassis base, and places the battery pack on the chassis base. Thus, the positioning pin hole and the positioning pin cooperate with each other to limit the horizontal upward movement of the battery pack on the chassis base.

[0032] Step A3: Control the locking push rod of each limiting mechanism to extend the side pin outward to the maximum limit position, and lock the bottom edge of the frame between the side pin and the short side of the frame base, so that the battery pack is vertically limited on the frame base.

[0033] Step A4: Control the electric telescopic rod of the locking push rod mechanism to extend outward, thereby pushing the male plug of the battery swapping docking to connect with the female plug of the battery swapping docking on the battery pack frame, so that the battery pack can provide power to the entire stacker.

[0034] Step B: Disassembly of the battery pack

[0035] Step B1: Control the electric telescopic rod of the locking push rod mechanism to extend and retract inward, thereby pulling the male plug of the battery swapping docking to separate it from the female plug of the battery swapping docking on the battery pack frame, and disconnecting the power supply of the battery pack to the entire forklift.

[0036] Step B2: Control the locking push rod of each limit mechanism to move inward, so that the side pin extends and retracts inward to the minimum limit position, thereby preventing the bottom frame of the frame from moving vertically upward without limit.

[0037] Step B3: Remove the battery pack from the chassis support. There are two removal methods, as detailed below:

[0038] Step B3-1, First disassembly method

[0039] The operator uses a forklift to lift the battery pack, causing the locating pin to separate from the locating pin hole, thus allowing the battery pack to move horizontally upwards without limit, thereby achieving the disassembly of the battery pack.

[0040] Step B3-2, Second disassembly method

[0041] Operators operate the crane and work with the lifting beam to separate the positioning pin from the positioning pin hole, thereby allowing the battery pack to move horizontally upwards without limit, thus enabling the battery pack to be disassembled.

[0042] The second method for quickly installing and removing batteries:

[0043] Step C: Battery Pack Installation

[0044] Step C1: Using a crane and lifting beam, move the fully charged battery pack directly above the chassis support of the forklift, and align the positioning pin holes on the battery pack frame with the positioning pins on the short side of the chassis support.

[0045] Step C2: Operate the crane to place the battery pack on the chassis base, so that the positioning pin hole and the positioning pin cooperate with each other to limit the horizontal upward movement of the battery pack on the chassis base;

[0046] Step C3: Control the locking push rod of each limiting mechanism to extend the side pin outward to the maximum limit position, and lock the bottom edge of the frame between the side pin and the short side of the frame base, so that the battery pack is vertically limited on the frame base.

[0047] Step C4: Control the electric telescopic rod of the locking push rod mechanism to extend outward, thereby pushing the male plug of the battery swapping docking to connect with the female plug of the battery swapping docking on the battery pack frame, so that the battery pack can provide power to the entire stacker.

[0048] Step D: Disassembly of the battery pack

[0049] Step D1: Control the electric telescopic rod of the locking push rod mechanism to extend and retract inward, thereby pulling the male plug of the battery swapping docking to separate it from the female plug of the battery swapping docking on the battery pack frame, and disconnecting the power supply of the battery pack to the entire stacker.

[0050] Step D2: Control the locking push rod of each limit mechanism to move inward, so that the side pin extends and retracts inward to the minimum limit position, thereby preventing the bottom frame of the frame from moving vertically upward without limit.

[0051] Step D3: Remove the battery pack from the chassis support. There are two removal methods, as detailed below:

[0052] Step D3-1, First disassembly method

[0053] The operator uses a forklift to lift the battery pack, causing the locating pin to separate from the locating pin hole, thus allowing the battery pack to move horizontally upwards without limit, thereby achieving the disassembly of the battery pack.

[0054] Step D3-2, Second disassembly method

[0055] Operators operate the crane in conjunction with the lifting beam to separate the positioning pin from the positioning pin hole, thereby allowing the battery pack to move horizontally upwards without limit, thus enabling the disassembly of the battery pack.

[0056] By employing the above technical solutions, the present invention has the following beneficial effects compared to the prior art:

[0057] 1. This invention integrates the high-voltage battery, heat dissipation, and control system of an existing forklift into a battery pack, enabling battery pack interchangeability. To achieve this interchangeability, this forklift is designed to meet the requirements. Furthermore, to meet the battery swapping requirements, the battery pack needs to be horizontally and vertically limited to prevent it from detaching from the forklift during use. The battery pack, main unit wiring, and high voltage are connected via electrically controlled horizontal plug-in connections. Battery swapping is performed using a forklift and / or crane.

[0058] 2. The present invention achieves horizontal upward positioning of the battery pack mounted on the chassis base by using the cooperation of the positioning pin and the positioning pin hole.

[0059] 3. The present invention uses at least two limiting mechanisms to vertically limit the battery pack frame and the vehicle frame base.

[0060] 4. The battery swapping process of this invention takes about 5 minutes, which is much faster than the existing charging time of 1.25 hours. This invention solves the problem of slow energy replenishment and inability to achieve long-term operation of new energy electric stackers. At the same time, the solution is economical and can be widely promoted. Attached Figure Description

[0070] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the invention, and therefore only show the components relevant to the invention.

[0071] In the description of this invention, it should be understood that the terms "left side," "right side," "upper part," "lower part," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. "First," "second," etc., do not indicate the importance of the components, and therefore should not be construed as a limitation of this invention. The specific dimensions used in this embodiment are only for illustrating the technical solution and do not limit the scope of protection of this invention.

[0072] like Figure 1 The diagram shows the structure of an existing forklift. It can be seen that the existing forklift uses a battery bracket 3 for the installation of the battery pack 1. The battery pack is covered by an exterior component and becomes a whole after installation. The whole cannot be disassembled. As a result, the existing forklift has the defects of non-removable batteries and inability to operate for a long time.

[0073] Example 1

[0074] This embodiment provides a preferred implementation scheme, such as... Figures 2 to 6 As shown, a type of electric new energy stacker with quick battery swapping is described, such as... Figure 2As shown, this forklift includes a chassis base 6, a battery pack, a battery swapping connector 10, and a locking push rod mechanism, wherein:

[0075] The aforementioned chassis base 6 connects the battery pack to the forklift, and the chassis base 6 is located on one side of the chassis 5. The chassis base 6 provides an installation position for the battery pack, and the battery pack is connected to the forklift through the chassis base 6. Specifically, the chassis base 6 is generally L-shaped, with its long side fixedly connected to the chassis 5, and the battery pack installed on its short side.

[0076] The aforementioned battery pack is used to provide power to the forklift. The battery pack is an independent power supply unit, comprising a frame 21, a battery pack 1, a charging port 17, a battery swapping connector 18, a high-voltage box 4, and a battery radiator 2. Specifically, the bottom surface of the frame 21 is adapted to the short side of the chassis support 6; the battery pack 1 is installed inside the frame 21; the high-voltage box 4 is connected to the battery pack 1, located above the battery pack 1, and is installed inside the frame 21, with the charging port 17 and the battery swapping connector 18 installed on the high-voltage box 4; the battery radiator 2 is connected to the battery pack 1, located above the battery pack 1, and is installed inside the frame 21, providing liquid cooling for the battery pack 1.

[0077] Furthermore, battery pack 1 comprises six battery boxes, divided into two groups of three. Each group of three battery boxes is connected in series to high-voltage box 4, and then connected in parallel with the interior of high-voltage box 4. High-voltage box 4 provides high-voltage electricity to the entire forklift, including all motors within the forklift, battery radiators 2, battery heating systems, etc. In addition, a control unit is installed inside high-voltage box 4 to monitor battery pack 1 information and provide real-time feedback to the battery control box. Simultaneously, high-voltage box 4 is equipped with a charging interface for high-voltage charging.

[0078] The aforementioned locking push rod mechanism is located on the short side of the chassis base 6, and the output end of the locking push rod mechanism is equipped with a battery swapping male connector 10; the battery swapping male connector 10 is connected to the main unit 15 of the forklift via a ribbon cable. When the battery pack is placed on the chassis base 6, the locking push rod mechanism pushes the battery swapping male connector 10 to move, so that the battery swapping male connector 10 connects with the battery swapping female connector 18.

[0079] Specifically, in this embodiment, the locking push rod mechanism includes an electric telescopic rod 11 mounting base and an electric telescopic rod 11. The electric telescopic rod 11 mounting base is set on the short side of the chassis base 6. One end of the electric telescopic rod 11 is installed on the electric telescopic rod 11 mounting base, and the other end of the electric telescopic rod 11 is fixed to the battery swapping connector 10.

[0080] To facilitate control over the connection between the male and female connectors of the battery swapping system, this implementation scheme also includes a lock / unlock button 13. The lock / unlock button 13 controls the extension and retraction of the electric telescopic rod 11 of the locking push rod mechanism, thereby controlling the connection between the male and female connectors of the battery swapping system. Pressing the lock / unlock button 13 transmits a signal to the vehicle's main unit 15, which then controls the drive motor of the electric telescopic rod 11, causing it to extend and retract, thus moving the male connector 10.

[0081] This implementation plan can also be equipped with a status indicator light 12. By cooperating with the lock / unlock button 13, the operator can observe the status of the status indicator light 12 to know the connection status between the male plug 10 and the female plug 18 of the power swapping docking.

[0082] This implementation scheme provides a horizontal upward limit for the battery pack mounted on the chassis base 6; specifically, it includes at least two positioning pins 8 and at least two positioning pin holes 22. The positioning pins 8 are located on the short side of the chassis base 6, and the positioning pin holes 22 are located at the bottom of the frame 21; the number of positioning pins 8 is the same as the number of positioning pin holes 22; when each positioning pin 8 engages with one positioning pin hole 22, the battery pack is positioned appropriately on the chassis base 6. Preferably, there are four positioning pins 8 and four positioning pin holes 22.

[0083] This implementation scheme provides a vertical upward limit for the battery pack installed on the chassis base 6; specifically, it sets up four limiting mechanisms. The four limiting mechanisms are distributed around the short side of the chassis base 6; and the locking push rods 7 of the two diagonally opposite limiting mechanisms extend in opposite directions, while the locking push rods 7 of the two limiting mechanisms on the same side extend in perpendicular directions.

[0084] Specifically, the limiting mechanism includes a locking push rod mounting base 14, a locking push rod 7, a side pin 16, and a guide seat 9. The locking push rod mounting base 14 is located on the short side of the chassis base 6. The locking push rod 7 is mounted on the locking push rod mounting base 14. One end of the side pin 16 is connected to the locking push rod 7, and the other end extends towards the external environment. The guide seat 9 is located in the extension direction of the side pin 16, and the side pin 16 passes through the guide seat 9 when the locking push rod 7 moves to its maximum limit position.

[0085] Furthermore, each guide seat 9 is located on the inner edge of the frame of the short side of the chassis base 6; when the battery pack is installed in the appropriate position on the chassis base 6, the side of each guide seat 9 facing away from the locking push rod mounting seat 14 contacts the frame 21 of the battery pack. This provides a certain guiding function when aligning the battery pack with the chassis base 6.

[0086] This implementation scheme has two disassembly methods. The first method involves setting two forklift holes 23 at the bottom of the battery pack frame 21. A forklift is used in conjunction with these holes to transport, install, and disassemble the battery pack. The battery pack weighs 2.4 tons, making manual handling difficult. The second method involves installing a lifting beam 19 above the battery pack frame 21, and then connecting the lifting beam 19 to the frame 21 via a lifting beam support 20. A crane is used in conjunction with the lifting beam 19 to achieve the lifting, installation, and disassembly of the battery pack.

[0087] This embodiment also provides a forklift machine, which uses the above-mentioned battery swapping device for battery installation and replacement.

[0088] This implementation scheme also provides a method for rapid battery loading and unloading using a forklift. This method utilizes the forklift with the aforementioned battery swapping device to perform rapid battery loading and unloading operations, specifically including the following two rapid battery loading and unloading methods:

[0089] The first method for quickly installing and removing batteries:

[0090] Step A: Battery Pack Installation

[0091] Step A1: Use a forklift to move the fully charged battery pack to the vicinity of the forklift's chassis base 6;

[0092] Step A2: The operator operates the forklift to align the positioning pin hole 22 on the frame 21 of the battery pack with the positioning pin 8 on the short side of the chassis base 6, and places the battery pack on the chassis base 6. Thus, the positioning pin hole 22 and the positioning pin 8 cooperate with each other to limit the horizontal upward movement of the battery pack on the chassis base 6.

[0093] Step A3: Control the locking push rod 7 of each limiting mechanism to run, so that the side pin 16 extends outward to the maximum limit position, and the bottom edge of the frame 21 is locked between the side pin 16 and the short side of the frame base 6, so that the battery pack is vertically limited on the frame base 6.

[0094] Step A4: The electric telescopic rod 11 of the locking push rod mechanism extends outward, thereby pushing the male battery swapping connector 10 to connect with the female battery swapping connector 18 on the battery pack frame 21, so that the battery pack provides power to the entire stacker.

[0095] Step B: Disassembly of the battery pack

[0096] Step B1: Control the electric telescopic rod 11 of the locking push rod mechanism to extend and retract inward, thereby pulling the male plug 10 of the battery swapping docking to separate it from the female plug 18 of the battery swapping docking on the frame 21 of the battery pack, and disconnecting the power supply of the battery pack to the entire stacker.

[0097] Step B2: Control the operation of the locking push rod 7 of each limit mechanism so that the side pin 16 extends and retracts inward to the minimum limit position, thereby preventing the bottom frame of the frame 21 from moving vertically upward without limit.

[0102] The operator operates the crane and works with the lifting beam 19 to separate the positioning pin 8 from the positioning pin hole 22, so that the battery pack can be moved horizontally upward without limit, thus realizing the disassembly of the battery pack;

[0103] The second method for quickly installing and removing batteries:

[0104] Step C: Battery Pack Installation

[0105] Step C1: Using a crane and lifting beam 19, move the fully charged battery pack directly above the chassis support 6 of the forklift, and align the positioning pin hole 22 on the frame 21 of the battery pack with the positioning pin 8 on the short side of the chassis support 6.

[0106] Step C2: Operate the crane to place the battery pack on the chassis base 6, so that the positioning pin hole 22 and the positioning pin 8 cooperate with each other to limit the horizontal upward movement of the battery pack on the chassis base 6.

[0107] Step C3: Control the locking push rod 7 of each limiting mechanism to run, so that the side pin 16 extends outward to the maximum limit position, and the bottom edge of the frame 21 is locked between the side pin 16 and the short side of the frame base 6, so that the battery pack is vertically limited on the frame base 6.

[0108] Step C4: The electric telescopic rod 11 of the locking push rod mechanism extends outward, thereby pushing the male plug 10 of the battery swapping docking to connect with the female plug 18 of the battery swapping docking on the frame 21 of the battery pack, so that the battery pack provides power to the entire stacker.

[0109] Step D: Disassembly of the battery pack

[0110] Step D1: Control the electric telescopic rod 11 of the locking push rod mechanism to extend and retract inward, thereby pulling the male plug 10 of the battery swapping docking to separate it from the female plug 18 of the battery swapping docking on the frame 21 of the battery pack, and disconnecting the power supply of the battery pack to the entire stacker.

[0111] Step D2: Control the operation of the locking push rod 7 of each limit mechanism so that the side pin 16 extends and retracts inward to the minimum limit position, thereby preventing the bottom frame of the frame 21 from moving vertically upward without limit.

[0112] Step D3: Remove the battery pack from the chassis support 6. There are two removal methods, as detailed below:

[0113] Step D3-1, First disassembly method

[0116] The operator operates the crane in conjunction with the lifting beam 19 to separate the positioning pin 8 from the positioning pin hole 22, thereby allowing the battery pack to move horizontally upwards without limit, thus achieving the disassembly of the battery pack.

[0117] This implementation plan integrates the high-voltage battery, cooling, and control system of the existing forklift into a battery pack, enabling battery pack interchangeability. To achieve this interchangeability, this forklift is specifically designed to meet the requirements. Furthermore, to meet the battery swapping requirements, horizontal and vertical limits are implemented on the battery pack to prevent it from detaching from the forklift during use. The battery pack and the main unit's 15-wire and high-voltage connections are electrically controlled horizontal plug-in connections. Battery swapping is performed using a forklift and / or crane. The battery swapping process in this implementation plan takes approximately 5 minutes, solving the problem of slow energy replenishment and inability to achieve uninterrupted operation in new energy electric forklifts. This solution is also economical and can be widely adopted.
