Technical Field
The invention belongs to the matching equipment of a new energy vehicle-mounted battery, and particularly relates to an emergency unlocking device of a vehicle-mounted battery box.
Background
With the continuous development of new energy technology, electric automobiles gradually become pets in the era. Compared with the traditional fuel automobile, the electric automobile has the problem of insufficient voyage capacity, and in order to improve the voyage capacity of the electric automobile, the battery box is usually required to be replaced in time to meet long-range operation. At present, a full-automatic unlocking device using electricity as power is commonly adopted for replacing the battery box, and the unlocking and shifting work of the battery box can be rapidly and efficiently completed. However, when an electric automobile is unexpected, such as extrusion and combustion, an automobile operation system is often caused to fail, and the battery box cannot be unlocked and shifted timely and quickly, so that a great potential safety hazard exists in the battery box, and the danger of spontaneous combustion and even explosion can be caused. Therefore, the battery box unlocking device is light and fast, and plays a vital role in avoiding and reducing personal risks.
The Chinese patent number ZL201120446346.6 discloses an electric automobile battery box unlocking device which is formed by connecting a left sub mechanism and a right sub mechanism through a quick connector device and comprises an unlocking hook combination, a handle combination and a rotation locking combination. When the electric automobile suddenly risks and the operation system breaks down, the unlocking and the shifting work of the battery box can be manually completed through the unlocking device, however, the device is complex in structural design, more in unlocking steps, and needs to be assembled before use, and the operation is low in working efficiency, particularly in dangerous conditions, the emotion of a person is tense, and the complex unlocking steps are unfavorable for rapidly taking out the battery box. Therefore, it is particularly important to design the battery box emergency unlocking device which is simple in structure and convenient to carry and operate.
Disclosure of Invention
Aiming at the defects of the prior art, the invention provides the emergency unlocking device for the battery box, which has the advantages of simple structure and convenience in operation, and can unlock the battery box rapidly when the electric automobile suddenly runs at risk and the running system fails, so that the emergency unlocking device is separated from a dangerous environment.
In order to achieve the technical purpose, the invention adopts the following technical scheme:
the emergency unlocking device for the battery box comprises a lever, supporting legs, movable joints, a rotating shaft, a middle shaft, a pulling disc, cylindrical pins and a guide head, wherein the supporting legs are hinged with the middle part of the lever; one end of the movable joint is connected with the front end of the lever, the rotating shaft is connected with the other end of the movable joint, the rotating shaft, the middle shaft and the guide head are of hollow structures and are sequentially connected with each other through a penetrating screw rod, and a cylindrical pin is further arranged between the middle shaft and the pulling disc.
As an optimal scheme, two ends of the movable joint are respectively connected with the lever and the rotating shaft in a bolt connection mode.
As a preferable scheme, the pulling disc is provided with two pin holes, the distances between the two pin holes and the central axis of the pulling disc are the same, and the angle formed by the two pin holes and the central axis of the pulling disc is 0-30 degrees.
Preferably, the pulling disc is a trisection pulling disc.
According to the technical scheme, compared with the prior art, the invention has the following advantages: the invention has simple structure, convenient operation, can be used as a vehicle-mounted tool, is operated in a handheld way, is reliable in control, and can quickly finish unlocking and shifting the battery box when dangerous emergency occurs and the operation system fails; in addition, the device has low cost and is easy for large-scale production and popularization.
