Technical Field

[0001] This utility model relates to agricultural machinery, specifically to an all-terrain new energy agricultural vehicle. Background Technology

[0002] Agricultural transport machinery refers to mechanical equipment used in the agricultural field. It is mainly used for transporting and handling materials, equipment, or agricultural products in agricultural production. Common agricultural transport machinery includes tractors, agricultural vehicles, transport vehicles, and agricultural trailers. These mechanical devices can be selected and configured according to different agricultural production needs to improve transportation efficiency and reduce labor intensity. Agricultural transport machinery plays a very important role in the transportation of agricultural products.

[0003] Currently, agricultural loaders in overseas markets such as the United States, Australia, and New Zealand generally use gasoline as fuel. However, their applications are mostly in the field, where land is sparsely populated and residential areas are far from farms, making refueling difficult. In addition, existing agricultural loaders generally use a two-wheel drive system, either front-wheel drive or rear-wheel drive, which makes them prone to getting stuck and difficult to get out of muddy roads. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this utility model provides an all-terrain new energy agricultural vehicle. This vehicle features a battery box installed under the seat, enabling electric drive and replacing the existing fuel-powered system. The two battery boxes control the front and rear drive motors respectively, saving energy for longer range and enabling part-time four-wheel drive. Combined with a MacPherson independent suspension system and a differential, the vehicle ensures the drive wheels remain on the ground even in harsh road conditions, maintaining driving performance and enabling all-terrain driving. Furthermore, the vehicle features both semi-closed and fully closed doors to meet different driving requirements, offering excellent practicality.

Combined with a MacPherson independent suspension system and a differential, the vehicle ensures the drive wheels remain on the ground even in harsh road conditions, maintaining driving performance and enabling all-terrain driving. Furthermore, the vehicle features both semi-closed and fully closed doors to meet different driving requirements, offering excellent practicality.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] An all-terrain new energy agricultural vehicle includes a frame, from front to back, comprising a cab, a driver's cab, and a loading box. The cab includes a cab frame covered by a cab cover. Two front-drive wheels are coaxially mounted on either side of the front end of the cab frame, both connected to the cab frame via MacPherson independent suspension. A front-drive motor for driving the two front-drive wheels is housed within the cab frame. A front motor controller for controlling the front-drive motors is also housed within the cab frame. The front motor controller is connected to a front differential fixed to the cab frame, and the front differential is connected to one of the front-drive wheels. The loading box includes a chassis frame with a cuboid-shaped box body on the chassis frame. Two rear-drive wheels are coaxially mounted on either side of the rear end of the chassis frame. Both are connected to the chassis frame via a MacPherson independent suspension. The axles of the two rear drive wheels are driven by a rear drive motor located under the chassis frame. The rear drive motor is connected to a rear motor controller, which is connected to a rear differential fixed to the chassis frame. The rear differential is connected to one of the rear drive wheels, and the rear drive wheel connected to the rear differential is on the same side as the front drive wheel connected to the front differential. A DC-DC converter is also installed under the chassis frame. The cab includes a driver's bracket with windshields on the front and rear sides. Doors are located on the left and right sides of the driver's bracket. Both doors are detachably connected to the front windshield, and the doors can be configured as either fully enclosed doors to close the cab or semi-enclosed doors to partially open the cab. Figure 2 As shown, the driver's cab is equipped with a seat, and below the seat are battery boxes that control the front drive motor and the rear drive motor respectively. Both battery boxes are controlled by a battery control box. Below the seat is also an on-board charger that can charge the two battery boxes.

[0008] In order to keep the cab cool in hot weather and warm in cold winter, thus improving driving comfort, an air conditioner is installed on the top of the cab, and the air conditioner is electrically connected to the battery box.

[0009] As a preferred technical solution, in order to facilitate the extrication of the loader from mud or breakdown, and also to provide the ability to tow trailers or help other vehicles get out of trouble, the front bottom of the loader is equipped with an electric winch and a trailer hitch.

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] 1. This agricultural vehicle has a battery box installed under the seat to achieve electric drive, changing the existing fuel drive method. The two battery boxes control the front and rear drive motors respectively, which saves electricity for longer range and enables part-time four-wheel drive. Combined with the MacPherson independent suspension and differential, the drive wheels can keep the drive wheels on the ground even in harsh road conditions, maintaining driving performance and enabling all-terrain driving. In addition, the doors are set as semi-closed and fully closed to meet the driving requirements under different working conditions, making it highly practical.

[0012] 2. A restraining towing rope is installed between the rear cargo door panel and the left and right cargo door panels. When the rear cargo door panel is lowered, it can be flush with the loading floor, thereby extending the usable cargo length of the cargo compartment.

[0013] 3. An electric winch and tow hook are installed at the bottom front of the truck, which can help the loader get out of trouble when it gets stuck in mud or breaks down. It can also tow trailers or help other vehicles get out of trouble. Attached Figure Description

[0021] like Figure 1The present invention provides a specific embodiment of an all-terrain new energy agricultural vehicle, comprising a frame, wherein the frame is arranged sequentially from front to back as a front end 1, a cab 2, and a loading compartment 3; the front end 1 includes a front frame 1-1, which is covered by a front cover 1-2; front drive wheels 1-3 are coaxially mounted on both sides of the front end of the front frame 1-1, and both front drive wheels 1-3 are connected to the front frame 1-1 via a MacPherson independent suspension mechanism 4; a front drive motor 1-4 for driving the two front drive wheels 1-3 is provided inside the front frame 1-1; a front motor controller 1-5 for controlling the front drive motor 1-4 is also provided inside the front frame 1-1; the front motor controller 1-5 is connected to a front differential 1-6 fixed on the front frame 1-1; the front differential 1-6 is connected to one of the front drive wheels 1-3; the loading compartment 3 includes a compartment base frame 3-1, which... The vehicle body 3-2 is a cuboid shape. For ease of transport and handling, pull rings 3-8 are embedded in its surface. Rear drive wheels 3-3 are coaxially mounted on both sides of the rear end of the chassis 3-1. The axles of the two rear drive wheels 3-3 are driven by a rear drive motor 3-4 located under the chassis 3-1. The rear drive motor 3-4 is connected to a rear motor controller 3-5. A DC-DC converter 3-7 is also located under the chassis 3-1. The cab 2 includes a driver's bracket 2-1. Windshields 2-2 are located on the front and rear sides of the driver's bracket 2-1. Doors 2-3 are located on the left and right sides of the driver's bracket 2-1. The two doors 2-3 are detachably connected to the front windshields 2-2. In this embodiment, hinges are used for the connection. The doors 2-3 can be configured as fully enclosed doors to close the cab 2 or semi-enclosed doors to partially open the cab. Figure 2 As shown, the cab 2 is equipped with seats 2-4. In this embodiment, three seats 2-4 are provided. Below each seat 2-4 is a battery box 2-5 that controls the front drive motor 1-4 and the rear drive motor 3-4 respectively. Both battery boxes 2-5 are controlled by a battery control box 2-6. The battery control box 2-6 can start one battery box 2-5 individually or both battery boxes 2-5 simultaneously. That is, the loader can be driven by the rear drive wheel 3-3 or the front drive wheel 1-3 individually, or by both the front drive wheel 1-3 and the rear drive wheel 3-3 simultaneously. To save power and ensure a longer driving range, in this embodiment, only the rear drive motor 3-4 is started on flat roads, and the front drive motor 1-4 and the rear drive motor 3-4 are started simultaneously when driving on rough roads. Below each seat 2-4 is also a vehicle charger 2-7 for charging the two battery boxes 2-5. Figure 3 As shown, in order to make the agricultural vehicle more suitable for rural roads with poor road conditions, this embodiment is equipped with high-flower tires for both front drive wheels 1-3 and both rear drive wheels 3-3.

[0022] An air conditioner 2-8 is installed at the top of the cab 2. The air conditioner 2-8 is electrically connected to the battery box 2-5, which can keep the cab 2 cool in hot weather and warm in cold winter, thus improving driving comfort.

[0023] The front bottom of the tractor unit 1 is equipped with an electric winch 1-7 and a tow hook 1-8, which can facilitate the extrication of the loader when it gets stuck in the mud or breaks down, and also provide the ability to tow trailers or help other vehicles get out of trouble.

[0024] When using this invention: On flat roads, the agricultural loader only needs to start the rear drive motor 3-4 for rear-wheel drive. On muddy or rugged roads, the front drive motor 1-4 is started simultaneously for dual-wheel drive. If a tire gets stuck, causing the front drive wheel 1-3 or rear drive wheel 3-3 to slip and prevent the vehicle from moving forward, the front differential 1-6 or rear differential 3-6 can be manually engaged to achieve different speeds for the two front drive wheels 1-3 or the two rear drive wheels 3-3. Alternatively, both the front differential 1-6 and rear differential 3-6 can be engaged simultaneously to achieve the same speed for the front and rear drive wheels on the same side, thus helping to get out of trouble. Alternatively, the controller can automatically control the vehicle. When the vehicle speed is no more than 5 km / h, if the controller detects that the speed of the front drive motor 1-4 or rear drive motor 3-4 is greater than 200 rpm and the higher-speed motor is slipping, it will automatically close the corresponding differential. The electrical schematic of the differential is shown below. Figure 4 As shown, combined with the MacPherson independent suspension mechanism 4, the drive wheels can remain on the ground even in harsh road conditions, maintaining driving performance and enabling all-terrain driving. When the road conditions are too harsh and a serious entrapment occurs, the vehicle can be freed with the help of external force through the electric winch 1-7 and the tow hook 1-8. When the battery box 2-5 cannot provide power to the motor, the batteries in the two battery boxes 2-5 can be charged through the on-board charger 2-7.

[0025] Of course, the above description is only a detailed description of the preferred embodiments of the present utility model in conjunction with the accompanying drawings, and is not intended to limit the scope of implementation of the present utility model. All equivalent changes made in accordance with the principles, construction and structure of the present utility model should be covered within the protection scope of the present utility model.
