Technical Field

[0001] The present invention belongs to the technical field of mine mechanical equipment, and particularly relates to an automatic closing mechanism for a battery connector of a new energy underground trackless equipment. Background Art

[0002] In recent years, with the rapid development of technologies such as battery performance, electric drive, driverless, and artificial intelligence, and the continuous improvement of price competitiveness, combined with the increasingly prominent series of problems of traditional underground trackless vehicles driven by diesel engines, such as high energy consumption, heavy pollution, high noise, low energy efficiency, and expensive operation and maintenance costs, the evolution trend of underground trackless equipment in mines towards pure electric and intelligent directions has become increasingly prominent. In addition, the breakthroughs in power battery technology and its control systems have provided a basis for the electrification of mine trackless equipment. The attention of each mine unit to pure electric trackless equipment has gradually increased, and trackless equipment manufacturers have also actively turned to the research and development of pure electric and intelligent trackless equipment.

[0003] With the successive introduction of relevant policies and the continuous breakthroughs in technologies related to mine pure electric vehicles and communication technologies, the trend of pure electrification and driverless (remote control) of underground trackless equipment has become even more obvious. "Electrification, automation, and intelligence" will be the inevitable trend of the development of underground mining and transportation equipment in mines, and safe, efficient, and clean mines will become an important development direction for the future mine industry.

[0004] However, due to the limitations of production technology requirements, the batteries that provide power for new energy underground trackless equipment are all of high power, large capacity, large weight, and large size. How to achieve automatic closing and disconnection of the battery connector has become a major problem. In the existing technology, the connection structure of the battery connector mostly relies on manual operation, with low efficiency and potential safety hazards, and it is difficult to meet the production requirements of automation and high efficiency in the complex underground environment. Therefore, there is an urgent need for a compact, safe, and reliable automatic closing mechanism to achieve rapid and accurate connection and separation of the battery connector. Summary of the Invention

[0005] The purpose of the present invention is to provide an automatic closing mechanism for a battery connector of a new energy underground trackless equipment, so as to solve the problem that the battery connector of the new energy underground trackless equipment cannot be efficiently automatically closed and disconnected, and to provide a mechanical structure that is convenient for installation, maintenance, safe, and reliable.

[0006] The technical solution of the present invention is: an automatic closing mechanism for a battery connector of a new energy underground trackless equipment, including a vehicle frame and a battery pack. A lifting mechanism is provided between the vehicle frame and the battery pack, and the lifting mechanism is connected with a lifting oil cylinder; a closing oil cylinder base is connected to the vehicle frame, a closing oil cylinder is provided on the closing oil cylinder base, the piston rod end of the closing oil cylinder is hinged with ear plates on both sides through a pin shaft, the ear plates are connected with a bracket, a connecting plate is fixed on the bracket, a connector plug is fixed on the connecting plate, a connector socket is fixed on the battery pack, and the connector socket is adapted to the connector plug.

[0007] As a further improvement of the present invention, a sliding seat is connected to the vehicle frame. A sliding cover is provided on the top of the sliding seat. A guiding rod penetrates through the middle of the sliding seat and the sliding cover, and the guiding rod is fixed to the bracket.

[0008] As a further improvement of the present invention, a bushing is provided on the pin shaft.

[0009] The beneficial effects of the present invention are as follows: When replacing the battery pack of the present invention, the lifting mechanism is driven by the lifting oil cylinder to act, and the battery pack is lifted to a certain height and locked in position. Then, the closing oil cylinder acts to push the connector plug to move straight forward, and exactly inserts the connector plug into the connector socket, and the connector is closed. When the battery pack descends, the closing oil cylinder acts to pull the connector plug to move straight backward, separates the connector plug from the connector socket, and the connector is disconnected. Then, the lifting oil cylinder drives the lifting mechanism to act, and the battery pack descends.

[0010] During this process, the guiding rod slides in the sliding seat and the sliding cover, so as to play a supporting and guiding role, ensuring that the connector plug moves in a straight line during the forward and backward movements.

[0011] The present invention is applied to underground trackless equipment, realizing the automatic closing and disconnection of the battery connector, and the closing and disconnection processes are stable and reliable. The structure of the present invention is compact, the structural design is reasonable, and it is convenient for installation and maintenance. It can also be used for other surface or underground equipment that requires automatic replacement of large-capacity batteries. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] When replacing the battery pack 16, the lifting oil cylinder 14 drives the lifting mechanism 13 to act. After the battery pack 16 is lifted to a certain height and locked in position, the closing oil cylinder 2 acts to push the connector plug 10 straight forward, and exactly inserts the connector plug 10 into the connector socket 12, and the connector is closed. When the battery pack 17 descends, the closing oil cylinder 2 acts to pull the connector plug 10 straight backward, separates the connector plug 10 from the connector socket 12, and the connector is disconnected. Then the lifting oil cylinder 2 drives the lifting mechanism 13 to act to lower the battery pack 17. The guide rod 3 plays a role of support and guidance to ensure that the connector plug 10 moves in a straight line during the forward and backward movement.
