Description

Technical Field

[0001] The utility model relates to the technical field of electric excavators, in particular to an electric excavator cabin arrangement structure and an electric excavator. Background Art

[0002] An electric excavator is an excavator that is powered by electricity. Compared with traditional excavators, electric excavators do not have engines, but are equipped with power batteries, motors, and controllers. They are cleaner and more environmentally friendly, and can reduce exhaust emissions and noise pollution. With the continuous development and popularization of electric technology, electric excavators are increasingly used in engineering construction, civil engineering, and the construction industry.

[0003] Existing electric excavators usually install large power batteries and hydraulic oil tanks on both sides of the cabin to improve the endurance of the electric excavator. However, with the upgrade of power battery performance, power batteries can support more powerful performance with a smaller volume, so there is extra idle space in the cabin where the power battery is installed, resulting in low space utilization of the cabin of existing electric excavators. Utility Model Content

[0046] In view of the problem that there is extra idle space in the existing electric excavator cabin where the power battery is installed, resulting in low space utilization of the cabin, the embodiment of the utility model arranges the larger battery pack and hydraulic oil tank separately on the upper layer of the second installation area, and the other smaller components are installed on the lower layers of the first installation area and the second installation area, thereby optimizing the layout space of the machine tool and improving space utilization.

A complete space can be reserved above the first installation area 101 for installing other components in the cabin, such as seats, operating levers, etc., thereby optimizing the layout space of the cabin, making the structure compact and improving space utilization.

[0050] Specifically, the length direction of the installation platform 1 is as follows Figure 2 As shown by arrow A in FIG. 1 , the width direction of the mounting platform 1 is as follows Figure 2 As shown by arrow B in FIG. The battery pack 10 of the embodiment of the utility model adopts a centralized structure, and the controller 4 adopts an all-in-one integrated controller to make full use of the space in the cabin. The battery pack 10 is used for high-voltage power supply of the electric excavator. The storage battery 5 is used for low-voltage power supply of the electric excavator and is installed on one side of the hydraulic main valve 2. The heat dissipation mechanism 8 includes a radiator and a heat dissipation fan, and the heat dissipation fan is installed on the outside of the radiator to take away the heat of the radiator.

The hydraulic oil tank 9 is connected to the hydraulic main pump 6 through a pipeline and is located above the hydraulic main pump 6. Since the hydraulic oil tank 9 needs to be connected to the hydraulic main pump 6, and the hydraulic main valve 2 is used to control the hydraulic circuit, the hydraulic oil tank 9, the hydraulic main pump 6 and the hydraulic main valve 2 are located on the same side of the installation platform 1, which can shorten the length of the pipeline and the connection path of the hydraulic main valve 2, thereby reducing the cost of use. Conventional pipelines such as oil suction hoses can be selected for the pipeline.

The electronic water pump 11 is provided with a first water inlet and a second water inlet, the first water inlet is connected to the water inlet of the motor 7 through a water pipe, and the second water inlet is connected to the water inlet of the heat dissipation mechanism 8 through a water pipe. Installing the electronic water pump 11 on the side of the motor 7 away from the first installation area 101 is convenient for repairing and maintaining the electronic water pump 11 on the one hand, and can shorten the length of the water pipe connecting the electronic water pump 11 and the motor 7 on the other hand, thereby reducing the use cost of the water pipe.

The side of the tank body 901 facing away from the battery pack 10 extends outward to form a protrusion 902, and the protrusion 902 is connected to the tank body 901. The side of the tank body 901 facing away from the battery pack 10 extends outward to form a protrusion 902, forming a special-shaped structure, which can expand the volume of the tank body 901 without affecting the space and volume of the battery pack 10. Interfaces and pipelines can be arranged on the unextended part of the side of the tank body 901 facing away from the battery pack 10, which can improve space utilization while ensuring the strength of the tank body 901. Specifically, in order to facilitate the installation of the hydraulic oil tank 9 and ensure the stability of the hydraulic oil tank 9, a plurality of support ears can be provided at the bottom of the hydraulic oil tank 9 to be fixedly connected to the mounting platform 1.
