Description

All-condition lithium battery stacker structure Technical Field

[0001] This work relates to stackers, particularly to a structure for a lithium battery stacker operating under all conditions. Prior Technology

[0002] Forklifts are widely used material handling equipment in logistics warehousing, manufacturing, and transportation industries. They primarily use a power system to drive the walking mechanism to complete the handling, stacking, and movement of goods. With increasing demands for environmental protection and energy efficiency, traditional internal combustion engine-powered forklifts are gradually being replaced by electric forklifts.

[0003] However, the existing forklifts have batteries and power systems located in scattered positions, making the configuration of the vehicle's interior space rather fragmented and the configuration of related components more difficult to integrate.

[0004] Therefore, it is necessary to provide a novel and progressive all-condition lithium battery stacker structure to solve the above problems. Summary of the Invention

[0005] The main purpose of this invention is to provide a full-condition lithium battery stacker structure that can improve space utilization and provide the power required for the operation of the drive module with the power supply module.

[0006] To achieve the above objectives, this invention provides a full-condition lithium battery stacker structure, comprising: a vehicle body forming an accommodating space; a transmission module disposed in the accommodating space, the transmission module including an electric motor, a gear set, and a differential, the gear set being drively connected between the electric motor and the differential; and a power supply module disposed in the accommodating space, the power supply module being electrically connected to the electric motor.

[0008] The following examples illustrate possible implementations of this invention, but are not intended to limit the scope of protection sought by this invention. The use of "a" or "at least one" before the terms mentioned herein does not limit the quantity; it may also be "plural" depending on the requirements. Such variations in quantity are also within the scope of protection sought, as will be stated in advance.

[0009] Please refer to Figures 1 to 5, which show one embodiment of the present invention. The full-condition lithium battery stacker structure 1 of the present invention includes: a vehicle body 10, a transmission module 20 and a power supply module 30.

[0010] The vehicle body 10 forms an accommodating space 11. The transmission module 20 is located within the accommodating space 11. The transmission module 20 includes an electric motor 21, a gear set 22, and a differential 23. The gear set 22 is drive-connected between the electric motor 21 and the differential 23. Specifically, the electric motor 21 is drive-connected to the gear set 22 via an output shaft, and the differential 23 is drive-connected to the gear set 22. A power supply module 30 is located within the accommodating space 11 and is electrically connected to the electric motor 21. This improves space utilization. The power supply module 30 provides the electric motor 21 with the necessary power for operation, and through the reduction and transmission of the gear set 22 and the differential 23, the transmission module 20 can accurately convert electrical energy into driving power, achieving a highly efficient and low-loss electric drive transmission effect.

[0011] In this embodiment, the full-condition lithium battery stacker structure 1 further includes a lifting device 80 and a plurality of wheels 90. The lifting device 80 is movably disposed on the vehicle body 10, and the plurality of wheels 90 are rotatably disposed on the vehicle body 10. The transmission module 20 can drive at least two wheels 90 to rotate and drive the lifting device 80 to move relative to the vehicle body 10.

[0012] The full-condition lithium battery stacker structure 1 further includes a control unit 40, which is mounted on the electric motor 21 and electrically connected to the power supply module 30. In this embodiment, the control unit 40 includes a battery monitoring unit 41 (BMS) and / or a charge / discharge control unit 42. The battery monitoring unit 41 is electrically connected to the power supply module 30, and the charge / discharge control unit 42 is electrically connected to the power supply module 30. Therefore, by incorporating the power supply module 30, the battery monitoring unit 41 (BMS), and the charge / discharge control unit 42 into the overall control architecture, the monitoring, management, and protection of the power supply module 30 (battery) and the coordinated operation between various electronic components can be realized.

[0013] To further explain, the electric motor 21, the transmission gear set 22, the differential 23, the control unit 40, and the power supply module 30 can be designed and tuned by the same manufacturer. After pre-matching and optimization, they are installed on the vehicle body 10, enabling modular replacement and achieving more precise torque management and higher kinetic energy conversion efficiency.

[0014] Specifically, the vehicle body 10 includes a housing 60, which encloses the accommodating space 11 on one side. The accommodating space 11 includes a first chamber 61 and a second chamber 64 that are interconnected. The transmission module 20 is disposed in the first chamber 61. The housing 60 has a platform 62 on the opposite side of the accommodating space 11. The platform 62 has an opening 63 that communicates with the second chamber 64. The power supply module 30 passes through the opening 63. The bottom 31 of one of the power supply modules 30 is located in the second chamber 64, and the top 32 of one of the power supply modules 30 protrudes from the opening 63 and the platform 62. Preferably, the all-condition lithium battery stacker structure 1 further includes a cover 70 and a chair 71. The chair 71 is disposed on the cover 70. The cover 70 is pivotally mounted on the vehicle body 10 and can be opened to close the opening 63. The cover 70 is provided with a receiving groove 72, and the top 32 of the power supply module 30 can be received in the receiving groove 72, which has high space utilization and can protect the power supply module 30. Preferably, the top 32 of the power supply module 30 is provided with at least one electrical contact hole 33. In this embodiment, as shown in Figure 3, the top 32 of the power supply module 30 has a plurality of electrical contact holes 33 around its periphery. At least some of these electrical contact holes 33 have different shapes, allowing for the insertion of different plugs. The flip-up cover 70 allows the plurality of electrical contact holes 33 to be directly exposed and located above the platform 62, thus enabling inspection of the power supply module 30 from above without disassembling the power supply module 30 or other structural components of the vehicle body 10. This facilitates maintenance and the removal and installation of wiring, ensuring good safety. Specifically, the all-condition lithium battery stacker structure 1 further includes a wire 2. One end of the wire 2 can be electrically connected to one of the electrical contact holes 33, and the other end of the wire 2 can be electrically connected to the control unit 40 through the opening 63. Accordingly, the power source (the power supply module 30) and the transmission module 20 are concentrated in one area (the first chamber 61 and the second chamber 64 connected together), which simplifies the configuration of the wires, greatly shortens the length of the high-voltage wire harness, and reduces the risk of incorrect wiring.

[0015] Preferably, the full-condition lithium battery stacker structure 1 further includes a DC converter 50, which is disposed on the power supply module 30 and electrically connected between the power supply module 30 and the control unit 40, so that the DC converter 50 and the power supply module 30 form a modular design, which is easy to disassemble and assemble, and further reduces the length of the line.

[0016] The power supply module 30 has a heat dissipation structure 100. In this embodiment, the heat dissipation structure 100 includes a plurality of heat dissipation holes 101 that connect the inside and outside of the power supply module 30, which can establish a natural convection or forced convection path to dissipate internal heat, so that the power supply module 30 can maintain the optimal operating temperature range in environments such as high temperature, continuous handling, and climbing slopes, thereby extending the cycle life of the power supply module 30.
