Description

Technical Field

[0001] This utility model relates to the field of transport vehicle technology, and in particular to a pure electric double-headed tanker truck. Background Technology

[0002] With the continuous advancement of urban construction and infrastructure development, the demand for concrete mixer trucks is constantly increasing. Traditional mixer trucks mostly adopt a fuel-powered, one-way driving structure, meaning that the vehicle's forward direction can only be controlled by a single cab. When reversing or turning around in narrow spaces, multiple directional maneuvers are often required, which not only reduces transportation efficiency but also poses significant safety hazards. Furthermore, the power systems of traditional fuel-powered mixer trucks are complex, energy-intensive, noisy, and produce severe emissions, making them increasingly difficult to meet the requirements of modern green construction and urban transportation environmental protection.

[0003] To improve the mobility and energy efficiency of transport vehicles, some technical solutions attempt to convert concrete mixer trucks into pure electric drive structures to reduce energy consumption and maintenance costs. However, these vehicles are generally still designed with a single cab and cannot achieve two-way driving control, which means that they still need to make frequent U-turns or reverse operations in construction sites, urban roads or narrow construction sites.

[0004] Therefore, we propose a pure electric dual-head tanker truck to solve the existing problems. Utility Model Content

[0005] The purpose of this utility model is to address the problems existing in the background technology by proposing a pure electric dual-head tanker truck.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a pure electric dual-head tanker truck, comprising a main driver's cab, a co-driver's cab, a frame unit, a power module, a drive suspension unit, a driven suspension unit, a mixing tank assembly, a hydraulic control unit, and an electronic control system. The main driver's cab and the co-driver's cab are respectively located at the front and rear ends of the frame unit, and both have complete driving control mechanisms. The main driver's cab and the co-driver's cab are interlocked through the electronic control system so that only one driver's cab can exercise driving control at any given time. The frame unit includes a frame body and mounting structures for mounting the steering mechanism, braking mechanism and stirring mechanism. The power module is a large-capacity battery pack including a BMS battery management system, which serves as the power source for the entire vehicle.

[0007] Preferably, the power module is fixedly installed on the bottom middle section of the vehicle frame unit via a battery bracket, and the battery pack output provides power for the vehicle's driving, braking, steering and stirring actions via a connection interface.

[0008] Preferably, the drive suspension unit includes a drive motor, a drive shaft, leaf springs, a steering drive axle, tires, and wheel rims, and the drive suspension unit is symmetrically mounted below the vehicle frame unit via leaf springs and suspension mounting brackets.

[0009] Preferably, the driven suspension unit includes a leaf spring, a steering brake axle, a tire, and a wheel rim, and the driven suspension unit is symmetrically mounted below the vehicle frame unit via the leaf spring and suspension mounting bracket.

The steering proportional valve group is connected in parallel with the accumulator, and the main relief valve is connected in series with the pressure sensor and the pressure gauge to form a closed-loop hydraulic control circuit.

[0011] Preferably, the mixing tank assembly includes a mixing tank, a mixing motor, and a mixing tank mounting platform.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model sets up a main driver's cab and a co-driver's cab at both ends of the frame unit and uses an electronic control system to achieve interlock control. Only one driver's cab has driving control at any time, thereby ensuring driving safety. This structure allows the vehicle to be driven from either end, realizing bidirectional driving and loading and unloading operations, and greatly improving the mobility in narrow construction sites, tunnels, mining areas and other places. The power module uses a large-capacity battery pack with a BMS battery management system as the sole power source for the vehicle, replacing the traditional combustion engine. It provides stable electrical energy for vehicle driving, braking, steering and mixing, and has the advantages of low energy consumption, low noise and zero emissions, which is in line with the trend of energy conservation and environmental protection. The power module is installed in the middle of the bottom of the frame, the mixing tank assembly is located in the middle of the frame, and the drive and driven suspension units are distributed at both ends of the frame, so that the vehicle can maintain a better balance in both fully loaded and unloaded states, improving driving stability.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Example 1 like Figures 1-5 As shown, the present invention proposes a pure electric dual-head tanker truck, including a main driver's cab 1, a co-driver's cab 2, a frame unit 3, a power module 4, a drive suspension unit 5, a driven suspension unit 6, a mixing tank assembly 7, a hydraulic control unit 8, and an electronic control system 9.

[0018] The driver's cab 1 and the passenger cab 2 are respectively located at the head and rear of the frame unit 3. Both have complete driving control mechanisms. The driver's cab 1 and the passenger cab 2 are interlocked through the electronic control system 9. When the driver's cab 1 is in the working state, the control circuit of the passenger cab 2 is automatically locked, and vice versa. This interlock logic ensures that only one control system is effective when the vehicle is traveling in any direction, avoiding driving conflicts and safety risks caused by misoperation. The interlock logic is implemented through the electronic control system 9. The driver needs to manually select the driving port in neutral. After switching, the control circuit of the other cab is automatically disconnected to avoid signal conflicts.

[0019] The frame unit 3 consists of the frame body and mounting structures for mounting the steering mechanism, braking mechanism and mixing mechanism, providing load-bearing support and assembly foundation for the whole vehicle.

[0020] The power module 4 uses a large-capacity battery pack with a BMS battery management system as the power source for the whole vehicle. It is fixed to the bottom middle section of the frame unit 3 by a battery bracket. The bracket is equipped with shock-absorbing rubber pads and protective plates, which can effectively reduce the transmission of vibration and impact from external objects during driving. The output end of the power module 4 is connected to the electronic control system 9 through a high-voltage power distribution interface to provide power for the vehicle's driving, braking, steering and stirring actions.

[0021] The drive suspension unit 5 is symmetrically mounted below the frame unit 3 and includes a drive motor, drive shaft, leaf springs, steering drive axle, tires, and wheel rims. The drive motor is directly connected to the drive axle and drives the tires to rotate through a reduction mechanism, enabling the vehicle to move forward and backward. The leaf springs are hinged to the frame unit 3 at both ends through suspension mounting brackets, forming a flexible suspension connection. The steering drive axle, in conjunction with the steering tie rod structure, can respond to steering operations from inside the cab, enabling flexible steering of the front wheels.

[0022] The driven suspension unit 6 is symmetrically mounted on the frame unit 3 and includes leaf springs, steering and braking axles, tires and rims. In addition to bearing the weight of the vehicle body, this structure can also provide steering and traction when the vehicle is moving in reverse. The leaf springs are also fixed to the bottom of the frame through suspension supports, which can play a role in buffering and shock absorption when the vehicle passes over uneven road surfaces, thereby improving the comfort and stability of the whole vehicle.

[0023] Example 2 like Figures 1-5As shown, the present invention proposes a pure electric dual-head tanker truck. Compared with Embodiment 1, this embodiment further includes: a mixing tank assembly 7 located in the middle of the frame unit 3, which is the main working unit of the vehicle. The mixing tank assembly 7 includes a mixing tank, a mixing motor, and a mixing tank mounting platform. The mixing tank is made of high-strength wear-resistant steel plate, and the inner wall is coated with an anti-corrosion layer to extend its service life. The mixing tank is connected to the frame unit 3 through a quick-release structure on the mounting platform, which facilitates maintenance, replacement, or disassembly. The mixing motor adopts a direct-drive coaxial arrangement and is coaxially connected to the rotating shaft of the mixing tank. The mixing speed is adjusted by the electronic control system 9 to achieve uniform mixing of concrete, mortar, or other materials.

[0024] The hydraulic control unit 8 is installed on the side of the frame unit 3 near the driver's cab 1. It mainly includes a hydraulic tank, a steering proportional valve group, an accumulator, a main relief valve, a pressure sensor, and a pressure gauge. The hydraulic oil flow and direction are controlled by the proportional valve group, which drives the steering mechanism to complete the direction adjustment. The accumulator is used to store and release hydraulic energy to ensure stable flow during the steering process. The main relief valve, pressure sensor, and pressure gauge are connected in series to form a closed-loop control circuit, which can monitor the oil pressure in real time and prevent overpressure damage. The hydraulic tank is equipped with an inspection port and a filter assembly for easy daily maintenance and oil replacement.

[0025] The electronic control system 9 is located on the side of the chassis unit 3 closest to the driver's cab 1, and includes a battery pack, a starting control circuit, a gear shifting device, an instrument panel, and lighting and signaling devices. The starting control circuit has a neutral start protection function to prevent accidental starting of the vehicle while it is in gear. The gear shifting device uses electrical signals to switch the drive motor in both directions to accommodate bidirectional driving needs. The instrument panel displays real-time information such as battery level, voltage, driving speed, and mixer tank speed, allowing the driver to monitor the vehicle's status. The lighting and signaling devices include front and rear lights, turn signals, brake lights, and warning lights to ensure safe driving at night or in inclement weather.

[0026] The vehicle adopts a two-way driving and two-head control structure design to achieve two-way traction and operation. The centrally arranged mixing tank assembly 7 and symmetrical suspension system make the vehicle's center of gravity distribution balanced, improving driving stability. The pure electric drive power module 4 significantly reduces noise and energy consumption, which is in line with the development direction of green energy saving and intelligent transportation.

[0027] The above specific embodiments are merely several preferred embodiments of this utility model.
