Description

Technical Field

[0001] This utility model belongs to the field of freight vehicle technology, and specifically relates to a tractor with a fixed battery pack that can be used with a quick-change battery pack. Background Technology

[0002] To promote green transportation and protect the environment, electric vehicles have become the future trend of the automotive transportation industry. Currently, major manufacturers mainly offer electric commercial vehicles. However, current electric vehicles only offer two independent configuration options: rechargeable fixed battery packs or battery swapping quick-swap battery packs. This makes the trade-off between achieving optimal vehicle weight and maximum driving range particularly prominent.

[0003] Currently, electric tractor vehicles on the market generally suffer from several unique drawbacks specific to freight transportation, such as short driving range, unreasonable axle load distribution, poor passability, and limited application scenarios. Utility Model Content

[0004] To address the aforementioned problems and current state of the existing technology, the purpose of this utility model is to first conventionally install a rechargeable fixed battery pack, and then, by cooperating with a quick-change battery pack located at the rear of the cab, increase the driving range, thereby enabling the electric tractor to quickly adapt to long-range driving scenarios; alternatively, it can optionally increase cargo capacity in short-range driving scenarios by not carrying the quick-change battery pack. After the widespread application of this utility model's solution, electric tractors will be able to adapt to different driving range requirements, allowing users to carry more cargo and carry less battery. The vehicle's application scenarios will be wider, it will be easier to adjust according to different conditions and needs, and the axle load distribution will be more reasonable, thereby greatly improving the versatility of electric tractors and reducing curb weight and cost.

[0005] Specifically, this utility model provides a tractor with a fixed battery pack that can be used with a quick-change battery pack. The power system of the tractor mainly includes: an electronic control unit assembly, a fixed battery pack, and a quick-change battery pack base.

[0006] The electronic control unit (ECU) is located below the cab of the tractor unit and is used to control the operation and / or charging of the fixed battery pack and the quick-swap battery pack base. The fixed battery pack, a rechargeable battery, is located on both sides of the tractor frame and serves as the tractor unit's primary power source, providing power for most usage scenarios. The quick-swap battery pack base is located adjacent to the rear of the cab on the tractor frame and has space above it to receive and accommodate the matching quick-swap battery pack.

[0007] Preferably, the fixed battery pack is generally configured as two units, respectively arranged on both sides below the tractor frame in the gap between the wheels and the cab. For some electric drive axle configurations, where the motor is integrated into the axle, the fixed battery pack can be configured as three units, one on each side below the frame and one in the middle.

[0008] Furthermore, to address heavy-load and / or long-range requirements, the power system of the tractor of this invention also includes a quick-swap battery pack. The quick-swap battery pack and its base form a mateable quick-swap plug-in structure, with the base providing power to the tractor. Both the quick-swap battery pack and its base utilize a universal quick-swap type battery pack / base, and different capacity quick-swap battery packs can be selected according to different range requirements, thus working in conjunction with a fixed battery pack to achieve heavy-load and / or long-range requirements.

[0009] The fixed battery pack for the tractor provided by this utility model, which can be used with a quick-swap battery pack, features high versatility, low cost, universal charging and swapping capabilities, and high reliability. It also allows for increased driving range by enabling a rear-mounted quick-swap battery pack. This achieves energy conservation, emission reduction, and lower operating and production costs. Furthermore, the solution of this utility model makes full use of the space layout of the tractor, without affecting existing structures or their connection to trailers. Attached Figure Description

[0013] The following description, in conjunction with the accompanying drawings, further illustrates the present invention, "a tractor with a fixed battery pack and capable of quick-change battery packs".

[0014] Example 1

[0015] See Figure 1-2This utility model first provides a tractor unit with a fixed battery pack and a quick-change battery pack. Its power system mainly includes: an electronic control unit assembly 1, two fixed battery packs 2, and a quick-change battery pack base 3. The electronic control unit assembly 1 is located under the cab; the two fixed battery packs 2 are located on the two sides and the lower center of the chassis, respectively, utilizing the space in the chassis; the quick-change battery pack base 3 is located on the chassis at the rear of the cab for future use. This embodiment is a configuration for short-range driving scenarios, meeting the requirements of short-range driving while significantly reducing the tractor unit's curb weight. This increases the overall load capacity of the vehicle, greatly improving loading efficiency and reducing the cost of the tractor unit.

[0016] Example 2

[0017] See Figure 3 This utility model provides a tractor unit with a fixed battery pack and a quick-swap battery pack. Its power system mainly includes: an electronic control unit assembly 1, two (or three) fixed battery packs 2, a quick-swap battery pack base 3, and a quick-swap battery pack 4. The electronic control unit assembly 1 is located under the cab; the fixed battery packs 2 utilize the space of the frame and are located in the middle of the lower part of the frame (two fixed battery packs 2 are located on both sides of the frame; three fixed battery packs 2 are arranged on both sides and in the middle of the frame); the quick-swap battery pack base 3 is located on the rear frame of the cab. For scenarios requiring long range, a quick-swap battery pack 4 connected via a quick-swap plug-in structure is mounted on the quick-swap battery pack base 3. The capacity of the quick-swap battery pack 4 can also be adjusted according to the scenario requirements, thereby increasing the driving range. This greatly improves the long-range capability of this electric tractor unit and achieves multi-purpose adaptability.
