[0021] like Figures 1-4 The diagram shows an electronic lock for a charging dock, used to lock a charging gun on a charging dock 100. The charging dock 100 is provided with an AC charging port 101 and a DC charging port 102. The electronic lock for the charging dock includes an electronic lock housing 1, a first locking rod 2, a second locking rod 3, a transmission mechanism 4, and a power component 5.
[0022] The electronic lock housing 1 has a locking end. The charging base electronic lock is mounted on the back of the charging base 100. The locking end is the end that is mounted on the back of the charging base 100, and it is also the end from which the first locking rod 2 and the second locking rod 3 extend. A first locking hole is provided on the side of the locking end, and a second locking hole is provided on the end face of the locking end. Specifically, the first locking hole faces inward from the side of the DC charging port 102, and the second locking hole faces the front of the second charging port. The second charging port is either an AC charging port 101 or a DC charging port 102, and the first charging port is either an AC charging port 101 or a DC charging port 102.
[0023] The first locking rod 2 is slidably disposed within the electronic lock housing 1, with its first end passing through the first lock hole and extending out of the electronic lock housing 1. The second locking rod 3 is slidably disposed within the electronic lock housing 1, with its first end passing through the second lock hole and extending out of the electronic lock housing 1. The first end of the first locking rod 2 extends from the outer side of the DC charging port 102 into the DC charging port 102, and the first end of the second locking rod 3 extends from the back of the charging base 100 to the front of the charging base 100. The second ends of the first locking rod 2 and the second locking rod 3 are both located within the electronic lock housing 1.
[0024] The power component 5 is connected to the transmission mechanism 4, which is connected to the first locking rod 2 to drive the first locking rod 2 to move. The transmission mechanism 4 is also connected to the second locking rod 3 to drive the second locking rod 3 to move.
[0025] In the embodiment, the electronic lock of the charging base is provided with two first lock holes and second lock holes with different orientations at the locking end of the electronic lock shell 1, as shown in Figure 1 、 Figure 2 The first lock rod 2 extends from the outer side of the first charging port into the DC charging port 102, and the second lock rod 3 extends to the front of the second charging port of the charging base 100. Meanwhile, the power member 5 drives the first lock rod 2 and the second lock rod 3 to perform extension and retraction movement through the transmission mechanism 4. In this way, the first lock rod 2 and the second lock rod 3 cooperate with the corresponding charging gun and the charging base 100, so as to lock the charging gun at the DC charging port 102 and the AC charging port 101 respectively. In this way, in the case of setting a single electronic lock, the charging gun can be locked at the AC charging port 101 and the DC charging port 102 respectively, the number of electronic locks is reduced, the structure is avoided to be repeated, and the cost of locking the gun is reduced.
[0026] The first lock rod 2 can be an AC lock rod or a DC lock rod, and the second lock rod 3 can be an AC (Alternating Current) lock rod or a DC (Direct Current) lock rod. Preferably, the first lock rod 2 is a DC lock rod, and the second lock rod 3 is an AC lock rod. In the embodiment, the AC lock rod and the DC lock rod extend from the end surface and the side surface of the locking end of the electronic lock shell 1 respectively. Specifically, the AC lock rod can be located at the rightmost side of the electronic lock shell 1. The AC lock rod and the DC lock rod are assembled in the electronic lock shell 1 at the same time, so as to meet the requirements of the national standard integrated electronic lock.
[0027] In some locking embodiments of the first lock rod 2 and the second lock rod 3, as shown in Figures 1 to 3 The first lock rod 2 is obliquely inserted into the DC charging port 102 at the back of the charging base 100, and the first lock rod 2 extends into the slot hole in the charging gun, forming a locking relationship with the charging gun. The second lock rod 3 extends from the front of the charging base 100, and a gun locking groove is arranged on the charging base 100 near the second lock rod 3. When the charging gun is inserted, the second lock rod 3 abuts against some movable reverse buckles on the charging gun, so that one end of the movable reverse buckle rotates into the gun locking groove, forming a locking relationship.
[0028] In some specific embodiments of the first lock hole, as shown in Figure 2 The first lock hole is inclined downward, and the sliding direction of the first lock rod 2 is the same as the axis direction of the first lock hole. The first lock hole is inclined downward from the side surface of the DC charging port 102 to the first charging port, so that the first lock hole can point to the first charging port axis as much as possible, and the first lock rod 2 can point to the first charging port axis as much as possible, thereby improving the locking effect of the first lock rod 2 on the charging gun.
[0029] In some embodiments of the charging base electronic lock, as shown in Figure 5 、 Figure 6The side of the second end of the second lock rod 3 is provided with a limiting slot 81.
[0030] The charging base electronic lock further comprises a locking rack 6 which is slidingly arranged in the electronic lock housing 1 and faces the limiting slot 81. As shown in Figure 8 As shown, the transmission mechanism 4 comprises a transmission gear 43 and a first gear shaft 411, the first end of the first gear shaft 411 is provided with a delay stroke slot 4111 arranged along the circumferential surface for delay transmission, the transmission gear 43 is arranged at the first end of the first gear shaft 411, the transmission gear 43 is provided with a transmission key 431 which extends into the delay stroke slot 4111, and the transmission gear 43 is engaged with the locking rack 6. The power member 5 is drivingly connected with the transmission gear 43. For power transmission of the transmission mechanism 4, when the locking rack 6 moves towards the limiting slot 81, the second lock rod 3 extends outwards, and when the second lock rod 3 moves to the locking position, the locking rack 6 extends into the limiting slot 81; otherwise, the locking rack 6 moves away from the limiting slot 81, and the second lock rod 3 retracts inwards.
[0031] In this embodiment, there is an angle range of idling without power transmission between the transmission gear 43 and the first gear shaft 411. When the second lock rod 3 extends to the locking position, the transmission gear 43 is directly or indirectly driven by the power member 5, the transmission gear 43 idles relative to the first gear shaft 411 until the transmission key 431 abuts against the side wall of the delay stroke slot 4111, forming a delay drive to the first gear shaft 411, so that when the second lock rod 3 moves to the locking position, the locking rack 6 extends into the limiting slot 81, forming a locking to the second lock rod 3, and at the same time, through the connection of the transmission mechanism 4, forming a locking to the first lock rod 2, thereby increasing the locking force of the first lock rod 2 and the second lock rod 3, forming an internal locking structure.
[0032] When the second lock rod 3 retracts from the locking position, at the beginning, the transmission gear 43 idles relative to the first gear shaft 411, the transmission gear 43 drives the locking rack 6 to move out of the limiting slot 81, and after a short period of time, the transmission key 431 abuts against the side wall of the delay stroke slot 4111, forming a delay drive to the first gear shaft 411, so that the locking rack 6 can be driven to move out of the limiting slot 81 first, and then drive the first gear shaft 411.
[0033] In this way, an internal self-locking structure capable of self-locking and unlocking is formed, thereby effectively increasing the locking force of the first lock rod 2 and the second lock rod 3.
[0034] The side of the second end of the second lock rod 3 is provided with a limiting slot 81, specifically, the limiting slot 81 can be directly arranged on the second lock rod 3, or can be arranged on the structure connected with the second lock rod 3. For example, as shown in Figure 5 、 Figure 6 As shown in the second sliding member 8 arranged below, the side of the second sliding member 8 is preferably provided with a limiting slot 81.
[0035] Further, as shown in Figure 5 , Figure 6 , the side of the limiting groove 81 close to the first end of the second lock rod 3 is an unlocking slope 811, when the second lock rod 3 is retracted, the unlocking slope 811 pushes the locking rack 6 to move, so that the locking rack 6 is separated from the limiting groove 81. Specifically, when the manual unlocking mechanism 10 is unlocked, the traction rope pulls the second lock rod 3 and the second sliding piece 8 to move. When unlocking, the first transmission group 41 below is operated, and the locking rack 6 is pushed to move at the same time. Specifically, the second lock rod 3 or the second sliding piece 8 reversely transmits power to the first transmission group 41, and when the power is transmitted to the first gear shaft 411, the first gear shaft 411 does not immediately transmit power to the second lock rod 3 or the second sliding piece 8 due to the delay stroke groove 4111. The unlocking slope 811 on one side of the limiting groove 81 abuts against the locking rack 6, and the locking rack 6 is pushed by the unlocking slope 811 to move away from the limiting groove 81, so that the locking rack 6 is separated from the limiting groove 81 when unlocking.
[0036] Of course, the end of the locking rack 6 towards the limiting groove 81 is provided with a chamfer or a guide slope for extruding and abutting against the unlocking slope 811, so as to increase the contact area of the locking rack 6 and the unlocking slope 811, and improve the stability of the locking rack 6 exiting from the limiting groove 81.
[0037] In some embodiments of the transmission mechanism 4, as shown in Figure 5 , Figure 6 and Figure 7 , the transmission mechanism 4 comprises a first transmission group 41 and a second transmission group 42.
[0038] The power piece 5 is directly or indirectly drivingly connected with the first transmission group 41 and the second transmission group 42, the first transmission group 41 is connected with the first lock rod 2 to drive the first lock rod 2 to move, and the second transmission group 42 is connected with the second lock rod 3 to drive the second lock rod 3 to move.
[0039] The transmission mechanism 4 comprises two transmission groups, one of which transmits power to the first lock rod 2, and the other of which transmits power to the second lock rod 3, so as to synchronously drive the lock rods to extend and retract. The power piece 5 can be directly and simultaneously drivingly connected with the first transmission group 41 and the second transmission group 42, or the power piece 5 can be directly drivingly connected with the first transmission group 41, and then drivingly connected with the second transmission group 42 through the first transmission group 41, or the power piece 5 can be directly drivingly connected with the second transmission group 42, and then drivingly connected with the first transmission group 41 through the second transmission group 42.
[0040] In addition, as shown in Figure 5 , Figure 6 and Figure 7 , the charging base electronic lock further comprises a first sliding piece 7 and a second sliding piece 8.
[0041] The first sliding member 7 is slidingly arranged in the electronic lock housing 1, and is connected with the first end of the first lock rod 2 to drive the first lock rod 2 to perform telescopic movement. The second sliding member 8 is slidingly arranged in the electronic lock housing 1, and is connected with the first end of the second lock rod 3 to drive the second lock rod 3 to perform telescopic movement. The electronic lock housing 1 is also provided with a sliding groove corresponding to the first sliding member 7 and the second sliding member 8, and the first sliding member 7 and the second sliding member 8 are slidingly arranged in the sliding groove.
[0042] The first transmission group 41 is connected with the first sliding member 7 to drive the first sliding member 7 to move, and the second transmission group 42 is connected with the second sliding member 8 to drive the second sliding member 8 to move. The power member 5 drives the first sliding member 7 and the second sliding member 8 to move through the transmission mechanism 4, and the first sliding member 7 and the second sliding member 8 respectively drive the first lock rod 2 and the second lock rod 3 to perform telescopic movement. In this way, the first lock rod 2 and the second lock rod 3 cooperate with the corresponding charging gun and charging seat 100, so as to lock the charging gun at the direct current charging port 102 and the alternating current charging port 101 respectively.
[0043] Further, the first sliding member 7 and the second sliding member 8 are both provided with a rack.
[0044] As shown in Figure 5 , Figure 6 and Figure 7 , the first transmission group 41 includes a first gear shaft 411 and a first bevel gear 412, the first bevel gear 412 is arranged at the first end of the first gear shaft 411, and the second end of the first gear shaft 411 is provided with a first gear 413 or a gear ring. Taking the first gear 413 as an example, the first gear 413 is engaged with the rack on the first sliding member 7. The second transmission group 42 includes a second gear shaft 421 and a second bevel gear 422, the second bevel gear 422 is arranged at the first end of the second gear shaft 421, the second bevel gear 422 is engaged with the first bevel gear 412, and the second end of the second gear shaft 421 is provided with a second gear 423 or a gear ring. Taking the second gear 423 as an example, the second gear 423 is engaged with the rack on the second sliding member 8. The power member 5 is directly or indirectly connected with the first bevel gear 412 and the second bevel gear 422, so as to respectively drive the first transmission group 41 and the second transmission group 42 to operate, and then output power to the first sliding member 7 and the second sliding member 8. The power member 5 is drivingly connected with the first bevel gear 412 or the second bevel gear 422, and preferably the power member 5 is engaged with the first bevel gear 412.
[0045] In addition, as shown in Figure 5 , Figure 6 and Figure 8As shown, for the first transmission group 41, the first transmission group 41 further comprises a transmission gear 43, which is arranged on the first gear shaft 411, and the power element 5 is drivingly connected with the transmission gear 43. The power element 5 is engaged with the transmission gear 43, and the transmission gear 43 transmits power to the first transmission group 41 through the first gear shaft 411, and the first transmission group 41 transmits power to the second transmission group 42, and finally to the first lock rod 2 and the second lock rod 3.
[0046] When the locking rack 6 locks the second lock rod 3, the first lock rod 2 and the second lock rod 3 move synchronously through the engagement of the first transmission group 41 and the second transmission group 42, forming synchronous locking of the first lock rod 2 and the second lock rod 3.
[0047] In some embodiments of the electronic lock shell 1, the side of the locking end is provided with an arc surface for adapting to the outer wall of the charging port, and a waterproof groove is arranged on the arc surface, as shown in Figure 3 、 Figure 4 As shown, a detachable waterproof elastic block 11 is arranged in the waterproof groove, and the waterproof elastic block 11 is provided with a first through hole through which the first lock rod 2 passes.

That is, when the first lock rod 2 extends out of the electronic lock shell 1, it passes through the second through hole on the rubber plug holder 12 and the first through hole on the waterproof elastic block 11 in sequence.
[0050] In some embodiments of the charging base electronic lock, as shown in Figure 5 、 Figure 6As shown, the charging base electronic lock comprises a reducer 9, the power member 5 is connected with the reducer 9, and the reducer 9 is connected with the transmission mechanism 4.
