[0027] To address the numerous problems associated with manual pallet trucks, lead-acid powered electric pallet trucks are currently commonly used for product handling. However, lead-acid charging takes up to 7 hours, delaying normal use. Furthermore, the main controller still uses mechanical locks for equipment locking, which not only makes the keys easy to lose and delays use but also hinders the overall intelligent development of the equipment. Therefore, there is an urgent need for a new energy electric pallet truck that can overcome the drawbacks of lead-acid powered electric pallet trucks for product handling.
[0028] The design concept of this application is to use lithium batteries as the power source and take advantage of the fast charging performance of lithium batteries to improve the drawbacks of lead-acid power-powered electric transport vehicles, avoid the impact of long-term charging on use, and use electronic locks to lock the equipment, completely solving the problem of equipment being unusable due to lost keys, increasing the safety and operability of the equipment, and also promoting the intelligent development of the overall equipment.
[0029] like Figure 1 As shown, this application provides a lithium-ion battery-powered electric transport vehicle, including an electric transport vehicle body. The electric transport vehicle body includes a frame, a power supply, an electrical system, a hydraulic system 7, and a drive system 8. The electrical system includes a main controller 4, an accelerator, and an instrument panel. The power supply is a lithium-ion battery 3. A wedge-shaped shell 5 is threadedly connected to the front side of the main controller 4. An electronic lock 6 is provided inside the wedge-shaped shell 5 and is electrically connected to the main controller 4.
[0030] The vehicle frame includes a fork 1 and a battery compartment 2, and the lithium battery power supply 3 is detachably placed inside the battery compartment 2; wherein a self-locking mechanism is provided between the bottom of the lithium battery power supply 3 and the battery compartment 2.

[0032] Using the existing press-type Beetle self-locking rebound mechanism for battery locking facilitates the rapid implementation of the solution. The battery can be locked and unlocked simply by pressing, making it very convenient to use. Users can also use other self-locking structures, which they can choose according to their own economic situation.
[0033] The battery compartment 2 adopts a lightweight aluminum alloy frame structure; the lightweight design is more conducive to reducing the weight of the equipment and reducing energy consumption.
[0034] The electronic lock 6 is a fingerprint lock or a password lock.
