Detailed Description
The present invention will be described in detail below with reference to the accompanying drawings and examples.
Referring to fig. 1 to 4, the self-locking device after charging and locking of the new energy vehicle in one embodiment of the invention includes a locking pin 1, a worm 2, a lead screw 4, a lead screw nut 3 and a motor 8, wherein the motor 8 is connected with the worm 2, the lead screw nut 3 is sleeved on the lead screw 4, the worm 2 is engaged with the lead screw nut 3, and the lead screw 4 is connected with the locking pin 1; the motor 8 drives the worm 2 to rotate, the worm 2 drives the screw rod nut 3 to rotate, and the screw rod nut 3 drives the locking pin 1 to move back and forth along the axial direction through the screw rod 4.
Further, the novel electric heating wire rope further comprises a shell 7, the worm 2, the screw rod 4, the screw rod nut 3 and the motor 8 are all arranged in the shell 7, and the motor 8 drives the locking pin 1 to stretch out and draw back inside and outside the shell 7.
Further, a gasket 6 is provided between the locking pin 1 and the housing 7.
Further, the lead screw nut 3 has an internal thread lead angle of not more than 5 degrees.
Further, the limiting and guiding structure on the housing 7 is: the locking pin 1 is matched with a shaft hole on the shell 7 for limiting, and the lead screw nut 3 at the bottom is matched to ensure that the locking pin 1 moves in the vertical direction.
Further, as shown in fig. 5, an emergency unlocking structure is further arranged on the housing 7, the emergency unlocking structure comprises an emergency unlocking handle 9, and a bevel gear 10, a primary duplicate gear 11 and a secondary duplicate gear 12 which are arranged in the housing, the emergency unlocking handle 9 is connected with the bevel gear 10, the bevel gear 10 is engaged with the primary duplicate gear 11, the primary duplicate gear 11 is engaged with the secondary duplicate gear 12, and the secondary duplicate gear 12 is engaged with the lead screw nut 3; the emergency unlocking handle 9 drives the bevel gear 10 to rotate, the bevel gear 10 sequentially drives the first-stage duplicate gear 11, the second-stage duplicate gear 12 and the screw nut 3 to rotate, when the electric control unlocking fails, the emergency unlocking handle can be manually operated by a person to drive a transmission mechanism matched with the emergency unlocking handle to cause the lock pin to return, and the situation that the charging gun cannot be smoothly separated from a charging port due to the electric control failure is guaranteed.
The working principle of the invention is as follows:
(1) the unlocking and locking functions are realized: a worm 2 and a helical gear on a shaft of a motor 8 are meshed with a lead screw nut 3 pair, a locking pin 1 is driven to do linear motion in the axis direction of the locking pin to further control unlocking and locking of the charging locking device, and in order to ensure that a lead screw thread pair can realize self-locking, a thread lead angle of a lead screw 4 is set to be not more than 5 degrees.
(2) The function of preventing accidental separation is realized: the locking mechanism is guided by a stop on the housing 7 and moves linearly with the force in fig. 1. When force in the direction shown in fig. 1 is applied, the driving force acts within the friction angle, the lead screw nut pair cannot be reversely driven to reversely rotate, so that the locking pin is retracted, and the locking function is ensured not to be invalid; when a rotation moment taking the force in fig. 1 as an axis is received, the rotation of the shell 7 is limited due to the limiting and guiding structure, and the locking mechanism cannot be opened. Therefore, the locking pin 1 can be ensured to be unlocked only after the unlocking force provided by the motor 8 or the emergency opening device is applied, and the situation that the charging socket is accidentally disengaged is prevented.
The above is only a preferred embodiment of the present invention, and certainly, the scope of the present invention should not be limited thereby, and therefore, the present invention is not limited by the scope of the claims.
