According to the utility model discloses battery plug mechanism 100, this battery plug mechanism 100 does not have the power supply, and accessible power battery 2 exerts the effect to it and accomplishes the cooperation grafting of its upper electric connector 1 and power battery 2 automatically.

With reference to the embodiment shown in fig. 1-7, the position-limiting device 3 has a clamping portion 30, the clamping portion 30 can be a clamping protrusion, the clamping portion 30 is clamped on the electrical connector 1 when the position-limiting device 3 is in the locked state to limit the movement of the electrical connector 1, and the clamping portion 30 is separated from the electrical connector 1 when the position-limiting device 3 is in the unlocked state, at this time, the power storage device 4 drives the electrical connector 1 to move toward the power battery 2, so as to complete the mating and plugging of the electrical connector 1 and the power battery 2.

Referring to fig. 1 to 7, the stopper 3 includes: first gag lever post 31, second gag lever post 32 and connecting rod 33, relative setting from top to bottom of first gag lever post 31 and second gag lever post 32, connecting rod 33 is connected between first gag lever post 31 and second gag lever post 32, electric connector 1 is located between first gag lever post 31 and the second gag lever post 32, wherein, all be provided with joint portion 30 on first gag lever post 31 and the second gag lever post 32, so that carry on spacingly to electric connector 1 from two places from top to bottom, can make spacing effect better.

As shown in fig. 1-7, the second limiting rod 32 is further provided with a limiting block 321, the limiting block 321 protrudes the second limiting rod 32 upwards, and in the process that the power battery 2 presses the limiting block 321, the second limiting rod 32 rotates around the first fixed rotating shaft 10, so that the clamping portion 30 on the second limiting rod 32 is separated from the electrical connector 1, and the connecting rod 33 drives the first limiting rod 31 to rotate around the second fixed rotating shaft 20, so that the clamping portion 30 on the first limiting rod 31 is separated from the electrical connector 1, and the electrical connector 1 is completely separated from the limiting effect of the limiting device 3 (see fig. 5 and 6). The second limiting rod 32, the first fixed rotating shaft 10, the connecting rod 33, the second fixed rotating shaft 20 and the first limiting rod 31 together form a link mechanism, so that when the power battery 2 applies an acting force to the limiting block 321 on the second limiting rod 32, the first limiting rod 31 can move along with the acting force, and no other external force is needed. Therefore, the operation process can be simpler and more reliable.

With reference to the embodiment shown in fig. 1-7, the upper surface of the stopper 321 is lower than the first end 511 of the force-transmitting device 5. That is, in the process of pressing the power battery 2 downward, the power battery 2 will first press the first end 511, and then can press the stopper 321. Therefore, the power battery 2 drives the force transmission device 5 to operate to drive the force storage device 4 to store force, and then drives the limiting device 3 to unlock the connecting piece by squeezing the limiting block 321, namely, the force storage device 4 already stores force before unlocking the connecting piece, once the electric connector 1 is unlocked, the force storage device 4 immediately pushes the electric connector 1 to move towards the power battery 2, so that the electric connector 1 is promoted to be matched and plugged with the electric connector 1.

Therefore, during the process that the power battery 2 presses the limiting block 321 downwards, the clamping portion 30 moves downwards along with the second limiting rod 32 to separate from the electrical connector 1.

Still further, the first stopper rod 31 and the second stopper rod 32 are connected to the connecting rod 33 via a floating rotary shaft 34. Therefore, the first limiting rod 31, the second limiting rod 32 and the connecting rod 33 form a link mechanism, and further the first limiting rod 31 can be driven to move upwards by the downward movement of the second limiting rod 32, so that the limiting blocks 321 on the first limiting rod 31 and the second limiting rod 32 are both separated from the electrical connector 1, and therefore the electrical connector 1 can swing off the limiting of the limiting device 3 and move under the driving of the power storage device 4.

Referring to fig. 1-7, power storage device 4 includes: the force storage plate 41 and the elastic element 42, the second end 512 of the force transmission device 5 is connected with the force storage plate 41, and both ends of the elastic element 42 respectively and elastically press against the force storage plate 41 and the electrical connector 1. When the power battery 2 presses the first end 511, the second end 512 presses the force storage plate 41, the force storage plate 41 moves towards the direction of the electrical connector 1 to press the elastic element 42, and the connecting member is limited by the limiting device 3 and cannot move, so that the force storage of the force storage device 4 is realized, and when the limiting device 3 unlocks the electrical connector 1, the electrical connector 1 pushes the electrical connector 1 outwards under the action of the elastic pushing force of the elastic element 42, so that the electrical connector 1 can move towards the direction of the power battery 2, and further completes the matching and plugging with the power battery 2.

Wherein the elastic element 42 may be a spring. Therefore, the structure is simpler and the power storage stability is better.

As shown in fig. 1-7, the force transfer device 5 comprises: a dowel 51 and a third fixed rotating shaft 52, the first fixed rotating shaft 10 being disposed between the first end 511 and the second end 512. Therefore, the power battery 2 can be extruded to the limiting block 321 after extruding the first end 511, so that the power storage of the power storage device 4 and the continuous operation of the operation of unlocking the electric connector 1 of the limiting device 3 are realized, and the accuracy of the matching and inserting of the electric connector 1 and the power battery 2 is further ensured.

Further, the dowel bar 51 is rotatable about a third fixed rotation shaft 52. That is, the transmission rod 51 and the third fixed rotating shaft 52 form a lever mechanism, so that the power battery 2 can drive the second end 512 to move simultaneously when pressing against the first end 511, so as to promote the power storage device 4 to store power.

According to some embodiments of the present invention, the elastic reset members are respectively disposed at the first fixed rotating shaft 10, the second fixed rotating shaft 20 and the third fixed rotating shaft 52. Therefore, the battery plugging mechanism 100 can be ensured to reset, namely recover to the initial state after the power battery 2 leaves the battery plugging mechanism 100, so that the automation of the whole process is realized, and the normal matching and plugging of the next power battery 2 and the electric connector 1 are not influenced.

Wherein, the elastic reset piece can be a coil spring. The coil spring occupies less space and is more convenient to arrange.

The operation of the battery plugging mechanism 100 is described in detail below with reference to fig. 1 to 7:

when the power battery 2 is placed on the battery plugging mechanism 100, the power battery 2 firstly touches and presses the first end 511, the first end 511 drives the dowel bar 51 to rotate around the third fixed rotating shaft 52, so that the second end 512 presses the power storage plate 41, and then the power battery 2 continues to move, so that the second end 512 pushes the power storage plate 41 to move, so that the power storage plate 41 compresses the elastic element 42 to complete power storage, and at this time, the electric connector 1 is limited by the limiting device 3 and cannot move (refer to fig. 2 and 3);

then, the power battery 2 continues to move until the power battery contacts the limiting block 321, and continues to move to press the limiting block 321, so that the second limiting rod 32 moves to drive the clamping portion 30 thereon to disengage from the electrical connector 1, and meanwhile, the second limiting rod 32 also drives the first limiting rod 31 to move through the connecting rod 33, so that the clamping portion 30 on the first limiting rod 31 also disengages from the electrical connector 1, so far, the electrical connector 1 is completely unlocked, and the electrical connector 1 moves towards the power battery 2 under the pushing of the elastic element 42 in the power storage device 4, so as to finally complete the matching insertion with the power battery 2 (refer to fig. 4-6);

and when power battery 2 leaves battery plug mechanism 100, first end 511 and stopper 321 do not all receive the effect of compressive force, because the effect of the restoring force that the elasticity piece that resets provided is used this moment, each part all resumes initial condition again to guarantee that power battery 2 can normally go on with the next grafting cooperation of electric connector 1 (refer to fig. 7).
