The anti-fall mechanism 23 is connected to the transmission unit 5 , and in this embodiment, the anti-fall mechanism 23 is preferably connected to both ends of the synchronous shaft 512 . The anti-fall mechanism 23 has a first state and a second state, and its first state is the state when an emergency occurs in the transmission unit 5, such as when the synchronous belt 513 breaks, the anti-fall mechanism 23 plays a role in ensuring the transfer of the entire battery. The device 10 maintains a state in a safe state (see FIG. 22 ); its second state is a state in which the entire battery transfer device 10 remains disengaged from the synchronous shaft 512 when it is in a normal working state (see FIG. 21 ).

Therefore, the working principle of the anti-fall mechanism 23 is as follows: when the transmission unit 5 is in normal operation, the anti-fall mechanism 23 is in the second state, and the anti-fall mechanism 23 is kept relatively far away from the synchronous shaft 512 of the transmission unit 5 to avoid the influence of the anti-fall mechanism 23 The transmission unit 5 drives the lifting of the battery pick-and-place unit 2; and when a special situation occurs (that is, when the synchronous belt 513 breaks), the anti-drop mechanism 23 restricts the rotation of the synchronous shaft 512 by engaging with the synchronous shaft 512, and then prevents The drop mechanism 23 switches from the second state to the first state, restricting the position of the battery pick-and-place unit 2, and no further large-scale ups and downs, so as to achieve the purpose of anti-falling and ensure that the pick-and-place unit is in a safe state under normal working conditions . The switching between the two states of the anti-drop mechanism 23 , that is, the different cooperation states jointly ensures the normal operation of the battery transfer device 10 .

The lever 231 switches between a first state and a second state. In this movement mode, the movement path of the limit rod 231 is simple, which is beneficial to improve the operational reliability of the anti-drop mechanism 23 .

Specifically, the limiting rod 231 is provided with an engaging tooth 2311 for engaging the synchronous shaft 512 on the side surface facing the synchronous shaft 512. The relationship between the timing belt 513 contact limit, the meshing tooth 2311 on the limit rod 231 is relatively far away from the synchronous shaft 512, so as to avoid affecting the normal rotation of the synchronous shaft 512; , the synchronous belt 513 cannot limit the limit rod 231 through the roller, so that the limit rod 231 makes a flip movement towards the direction close to the synchronous shaft 512, so that the meshing teeth 2311 are engaged with the synchronous shaft 512, so as to prevent the synchronous shaft 512 from further rotating , to achieve the purpose of anti-falling.

In this embodiment, when the limit rod 231 is switched from the second state to the first state along the direction indicated by the arrow in FIG. The engagement of the wheel 512c realizes the function of limiting and fixing the synchronous shaft 512 to continue to rotate, strengthens the cooperation effect between the synchronous shaft 512 and the limiting rod 231, and realizes the anti-falling measures of the anti-falling mechanism 23. By arranging the engaging wheel 512c on the surface of the synchronous shaft 512 to achieve engagement with the limit rod 231 , it is also possible to avoid damage to the surface of the synchronous shaft 512 caused by the engagement, which is beneficial to the long-term operation of the synchronous shaft 512 .

Among them, the elastic member 233 shown in Figure 15 is only used to illustrate the preferred setting position of the elastic member 233 and the connection relationship with the limit rod 231, and the elastic member 233 can specifically adopt all the parts that can generate elasticity in the prior art , so as to maintain the force applied to the limit rod 231 to switch to the first state.

In this embodiment, the elastic member 233 is preferably a coil spring. By setting the elastic member 233 to exert a force on the limit rod 231, no matter what state the anti-drop mechanism 23 is in, the force of the elastic member 233 makes the limit rod 231 always In a state of being bounced up at a high position, after the synchronous belt 513 is accidentally broken, the force exerted by the elastic member 233 enables the limit lever 231 to switch to the first state faster, thereby quickly realizing the synchronous shaft 512. The fastening and fixing enhances the anti-falling efficiency of the limit rod 231 and makes the anti-falling response of the anti-falling mechanism 23 fast.

Wherein, the preferred setting range of the elastic member 233 is as follows: within the included angle between the limiting rod 231 and the battery pick-and-place unit 2 , and its installation position can be set at any position of the included angle as required. In this embodiment, the elastic member 233 is arranged at the farthest position from the connection between the limiting rod 231 and the fixing seat 232, that is, one end of the elastic member 233 is arranged at the farthest end point of the limiting rod 231 away from the fixing seat 232 The other end of the elastic member 233 is disposed on the battery pick-and-place unit 2 at a corresponding distance from the fixing base 232 .

In addition, as shown in FIG. 24 and FIG. 25 , the transmission unit 5 also includes an anti-off gear assembly 54, and the anti-off gear assembly 54 includes a plurality of back wheel sets 541, and the plurality of back wheel sets 541 correspond to the rack and pinion transmission unit one by one.

The back wheel group 541 of this anti-off gear assembly 54, by setting the back wheel 5411 that is positioned at the back side of rack 53, utilizes two back wheels 5411 in this back wheel group 541 to respectively pair gear 52 relative to the tooth surface of tooth bar 53 Limiting is carried out in the vertical direction and the horizontal direction to ensure that the gear 52 can be meshed on the tooth surface and will not disengage from the vertical and horizontal directions, so that the gear 52 can maintain stable meshing with the rack 53, and the transmission is more stable. Wherein, the battery pick-and-place unit 2 is clamped on the rack 53 from three directions by the gear 52 and the two back wheels 5411 of the back wheel set 541 , which can also reduce the stress on the gear 52 and make the gear 52 not easily damaged. Compared with the back wheel 5411 of the back wheel set 541, which is limited from other directions, the position is changed from the other side of the gear 52 relative to the rack 53 to the back and side respectively, which also reduces the battery transfer device 10. The volume reduces the occupied space and reduces the cost of the substation 100 .

As shown in Figure 25, in a plane perpendicular to the axis of the rack 53, two back wheels 5411 that limit the vertical and horizontal directions of the tooth surface of the gear 52 relative to the rack 53 form a back wheel group 541 .

When the gear 52 rolls up or down on the rack 53, the forces on the upper side and the lower side of the meshing position of the gear 52 and the rack 53 are mutually balanced, which is beneficial to ensure that the gear 52 is meshed with the rack 53. The stress distribution is always consistent, which is beneficial to improve the service life of the gear 52 and the rack 53 . At the same time, compared with the battery pick-and-place unit 2, this design enables the battery pick-and-place unit 2 to be supported by back wheels 5411 on the upper and lower sides in the vertical direction, which is conducive to making the battery pick-and-place unit 2 run more smoothly during the lifting process. In order to ensure the operation stability of the battery swapping station 100 and reduce the abnormal noise during operation.
