As shown in fig. 1-3, an unlocking device of a double-lock-rod electronic lock comprises a shell 1 and two lock rods 2 which are arranged in the shell 1 and can partially extend out of the shell, wherein the unlocking device comprises a pressing part 3 arranged outside the shell, an unlocking part 4 arranged in the shell, and a push rod 5 with two ends respectively connected with the pressing part 3 and the unlocking part 4, wherein the pressing part 3 is pressed, and the unlocking part 4 is driven to move and push the two lock rods 2 to enter an unlocking state by the push rod 3.

Specifically, the integrated design of the double-lock-rod electronic lock is that an AC charging end and a DC charging end of a charging seat are provided with locking functions, the double-lock-rod electronic lock comprises a shell 1 and a double-lock rod 2 arranged in the shell 1, and the unlocking of the double-lock rod cannot be realized by the existing single-lock-rod unlocking device, so the inventor designs an unlocking device of the double-lock-rod electronic lock aiming at the double-lock-rod electronic lock, the unlocking device comprises a pressing part 3 and an unlocking part 4, a push rod 5 connected with the pressing part and the unlocking part, the pressing part 3 is pressed by using external force, the push rod 3 is driven to further drive the unlocking part 4 to move, and the two lock rods 2 are pushed to enter an unlocking state. The unlocked state is that the unlocking device moves the lock lever 2 from the locking position to the unlocking position.

Specifically, the double-locking-rod cylinder lock further comprises a driving unit 10 and a transmission mechanism 9 connected with the output end of the driving unit 10; the transmission mechanism 9 includes a freely rotatable swing arm member, and the swing arm member includes a first swing arm 7 and a second swing arm 8 which are disposed opposite to each other as described below, and the first swing arm 7 and the second swing arm 8 are connected with the two lock levers 2, respectively.

The pressing part 3 is arranged outside the shell 1, the unlocking part 4 is arranged inside the shell 1, one end of the push rod 5 is fixedly connected with the unlocking part 4, and the other end of the push rod penetrates through the shell 1 and is fixedly connected with the pressing part 3.

In this embodiment, the pressing portion 3 is provided with an axially penetrating stepped hole 32, the stepped hole 32 includes a large hole and a small hole formed by radially shrinking along the pressing direction, and the push rod 5 is provided with a radially recessed clamping groove 51 matching with the stepped hole 32, and the small hole is clamped with the clamping groove 51.

Thus, by providing the pressing portion 3 and the unlocking portion 4, pressing the pressing portion 3 achieves that the unlocking portion 4 pushes the lock lever into the unlocked state.

As shown in fig. 3 and 5, an elastic member 6 is further provided between the pressing portion 3 and the outer wall of the housing 1, and the elastic member 6 returns the unlocking device to the initial position.

Preferably, the pressing part 3 is provided with a groove 31 toward the side of the housing 1, and the elastic member 6 is partially disposed in the groove 31.

Specifically, an elastic member 6 is disposed between the pressing portion 3 and the outer wall of the housing 1, the pressing portion 3 includes a groove 31, the elastic member 6 is sleeved on the push rod 5, one end of the elastic member 6 contacts with the bottom wall of the annular groove 31, that is, the elastic member 6 is partially disposed in the groove 31, and the other end of the elastic member 6 contacts with the outer wall of the housing 1 and is configured to be compressed under the action of an external force so as to drive the unlocking portion 4 to move and trigger the unlocking action; when the unlocking device is in a natural state, the elastic member 6 is naturally elongated, and when the unlocking device is in a pressed state, the elastic member 6 is in a compressed state. When the unlocking device is unlocked, the elastic piece 6 enables the unlocking device to return to a natural state, namely an initial position through self elastic force. Meanwhile, in order to secure the strength of the pressing portion 3, a plurality of reinforcing plates for increasing the strength are also uniformly arranged on the bottom wall of the groove 31 of the pressing portion 3.

Preferably, the elastic member 6 is a spring, and the elastic force value of the spring is 3N-15N.

Specifically, the inventor obtains through calculation and test that, when the elasticity value is less than 3N, presses the condition that the pressing part 3 makes unlocking device be in the unblock state, when withdrawing external force, the spring force can not make unlocking device naturally rebound to initial position, simultaneously, when the elasticity value is less than 3N because the elasticity value is too little, easily causes the mistake to bump and makes its double lock bar electronic lock enter the unblock state from the locking state, causes the maloperation. When the elastic force value is larger than 15N, the elastic force value is too large, and when an operator presses the pressing part 3, the pressing part 3 cannot move, so that unlocking of the double-lock rod electronic lock is completed, and the inventor selects the elastic force value of the spring to be in the range of 3N-15N.

Therefore, the natural resilience of the unlocking device is realized by setting the elastic force value of the spring, and the unlocking part can be moved by external force to realize unlocking.
