In a specific embodiment, one of the detecting member and the triggering member is a limit switch, and the other one is a limit table matched with the limit switch, and when the limit switch is matched with the limit table, the limit switch is triggered to generate a stroke control signal. In the present embodiment, the travel limiting device is described by taking the detecting element as a limit switch and the triggering element as a limit platform as examples, it should be understood that in other embodiments, the detecting element may be set as a limit platform, and the triggering element may be set as a limit switch to implement the travel limiting device.

Fig. 2 shows a schematic structural diagram of the battery transfer device in this embodiment, wherein the limit switch 30 may be fixed on the battery transfer apparatus 10 by a fixing member, and the limit switch 30 may trigger generation of a stroke control signal by matching with the limit station 40, so as to control the battery transfer apparatus 10 to stop walking in the direction toward the limit station 40.

Fig. 3 shows a schematic structure of the limit switch 30 in the present embodiment. The limit switch 30 in this embodiment includes a rotatable touch rod 31 and a switch body 32, and a first electrode plate is disposed at one end of the touch rod 31 connected to the switch body 32.

In the moving process of the battery transfer equipment 10, the touch rod 31 can rotate after touching the limit table 40, the touch rod 31 rotates to a preset angle under the action of the limit table 40, the limit switch 30 is in the first state, the first electrode plate rotates to the position where the second electrode plate touches along with the first electrode plate, the second electrode plate is arranged inside the limit switch 30 and is electrically connected to a signal generating unit inside the limit switch 30, when the first electrode plate touches the second electrode plate, an internal communication circuit of the limit switch 30 is conducted, the trigger signal generating unit generates a stroke control signal, and therefore the battery transfer equipment 10 is controlled to stop moving forwards continuously through the stroke control signal.

Fig. 4 shows a schematic structural view of the stopper table 40 in the present embodiment.

In one scenario, the limiting table 40 includes an upper end surface 412 parallel to a horizontal plane, when the battery transfer device 10 moves from a direction away from the limiting table 40 to a direction close to the limiting table 40, after the touch rod 31 contacts one side of the limiting table 40, due to continuous actuation of the battery transfer device and obstruction of the limiting table 40, the touch rod 31 rotates in the direction away from the limiting table 40, wherein a preset angle may be preset, and a distance relationship between the preset angle and the first electrode sheet and the second electrode sheet is preset, when the angle of the touch rod rotation is greater than or equal to the preset angle, the first electrode sheet contacts the second electrode sheet, and the signal generating unit generates the stroke control signal.

In order to avoid that the rotation angle caused by interference can also enable the touch rod 31 to trigger the limit position signal, and ensure that the battery transfer device 10 can normally operate when not reaching the limit position, in this way, the upper end surface 412 should be provided with a certain height, so that the limit table 40 blocks the touch rod to enable the touch rod 31 to rotate at least a certain angle to trigger the limit position signal.

In order to avoid that the rotation angle caused by the interference may also cause the touch bar 31 to trigger the limit position signal, and ensure that the battery transfer device 10 can normally operate when the limit position is not reached, the limit table 40 should enable the touch bar 31 to rotate at least a certain angle to trigger the limit position signal, that is, the inclined surface 411 should be provided with a certain angle.

In a specific embodiment, the trigger signal generating unit generates the stroke control signal when the touch lever 31 is in contact with the joined portion of the upper end surface 412 and the inclined surface 411.

In this way, the inclined surface 411 buffers the touch rod 31 to change the rotation angle of the touch rod 31, so that the touch rod 31 is prevented from being impacted by the limiting table 40, and the friction between the edge of the upper end surface and the surface of the touch rod in the moving process of the battery transfer equipment causes the touch rod to be damaged, thereby affecting the accurate generation of the limit position signal, and further improving the limiting reliability.

The present embodiment can prevent the excessive rotation by maintaining the rotation angle of the touch bar 31 through the upper end surface 412 of the stopping block 40.

In a specific embodiment, in order to avoid the situation that the surface of the touch bar 31 or the limit stop 40 may be damaged due to excessive friction generated when the touch bar 31 contacts the limit stop 40, the contact portion of the touch bar 31 and the inclined surface 411 may be configured as a roller structure.

Specifically, as shown in fig. 5, a guiding mechanism 50 may be disposed on the traveling path for guiding the movement of the battery transfer device 10, the battery transfer device 10 may be configured to move along the guiding mechanism 50, the limiting point may be disposed on the guiding mechanism 50, and a connecting line between the trigger and the limiting point is perpendicular to the guiding mechanism 50, that is, the trigger is disposed at a predetermined distance from the guiding mechanism, so as to further ensure that the battery transfer device 10 can move within a range as large as possible under the condition of limiting.

It should be understood that, in this embodiment, the number of the detecting elements and the number of the triggering elements may be set according to actual situations, for example, when only one direction of the battery transfer device 10 needs to be limited, only one detecting element may be set, and a corresponding triggering element is set at a position corresponding to the direction, and when the detecting element is specifically set, the detecting element is set toward the triggering element; when the battery rotating equipment needs to be limited in two directions of a walking path of the battery rotating equipment, two detection pieces and limiting pieces respectively corresponding to the two detection pieces in the two directions can be arranged to limit the two directions at the same time, and when the battery rotating equipment is specifically arranged, the two detection pieces are respectively arranged towards the corresponding trigger pieces; of course, when two directions need to be limited, one detection piece can be arranged, and two trigger pieces are arranged at corresponding positions of the two direction limiting points. In this embodiment, the number of the detection pieces and the number of the trigger pieces can be flexibly set.

It should be understood that, in the present embodiment, when there are two detecting members, the two detecting members may be located at one side of the battery transferring apparatus 10 at the same time, or may be located at two sides of the battery transferring apparatus 10 respectively, and the limiting member matched with the detecting member and the corresponding detecting member are disposed at the same side.
