As shown in fig. 11, the two elevation detection following portions 52 have a first following point 53 and a second following point 54, respectively; the first follow-up point position 53 corresponds to a first preset lifting position, i.e., the highest position, of the battery mounting part 2; the second follow-up point position 54 corresponds to a second preset elevating position, i.e., the lowest position, of the battery mounting portion 2. As shown in fig. 10 and 11, the battery mounting portion 2 is located at the lowest position, and the second following point 54 is located at the position corresponding to the elevation detection fixing portion 51. In the present embodiment, the two lifting detection fixing parts 51 are both hall sensors, and the materials at the first following point 53 and the second following point 54 are both metals that can be sensed by the hall sensors.

Two lifting detection follow-up parts 52 are arranged to correspond to the highest position and the lowest position of a lifting path of the battery installation part 2 respectively, when the battery installation part 2 lifts or descends in place, the lifting detection fixing part 51 just can sense a first follow-up point 53 or a second follow-up point 54, sensed signals are sent to the control module, the control module sends electric signals to the driving part to control the driving part to stop moving, the driving part is prevented from driving the battery installation part 2 to move continuously, the battery installation part 2 is enabled to deviate from a preset position or the lifting device 1 is damaged, and the stability and the safety of the lifting device 1 are improved.

In the present embodiment, the lifting detection following portion 52 and the lifting member 30 are coaxially disposed and are both disposed on the rotating shaft 20, so as to ensure the synchronism of the lifting detection following portion 52 and the lifting member 30, so that the rotation condition of the lifting member 30 detected by the detection assembly has no deviation, and it can directly reflect whether the battery mounting portion 2 is lifted and lowered in place.

In the present embodiment, the lifting position detection mechanism 50 is provided corresponding to the rotating shaft 20, and detects the rotational position of the rotating shaft 20 to obtain the position of the lifter 30 and thus the position of the battery mounting portion 2, so as to control the lifting of the battery mounting portion 2, and the detection method is simple.

In the present embodiment, the stroke detection mechanism 40 of the detection assembly obtains the position of the battery mounting portion 2 by detecting the position of the driving portion, and the elevation position detection mechanism 50 obtains the position of the battery mounting portion 2 by detecting the rotational position of the lift 30, i.e., the rotational shaft position of the rotational shaft 20. Specifically, no matter whether the sliding member 13 of the driving portion drives the follower 42 to move to correspond to any one of the fixing members 41, so that the fixing member 41 senses the follower 42 and sends an electrical signal to the control module, or the rotating shaft 20 drives the first following point 53 or the second following point 54 on the lifting detection following portion 52 to move to correspond to the position of the lifting detection fixing portion 51, so that the lifting detection fixing portion 51 senses and sends an electrical signal to the control module, and the control module can send an electrical signal to the motor to control the motor to stop moving. Meanwhile, the position of the battery mounting part is obtained by the stroke detection mechanism 40 and the lifting position detection mechanism 50, and the lifting of the battery mounting part can be correctly controlled when the stroke detection mechanism 40 or the lifting position detection mechanism 50 fails.

In other embodiments, the detection component may also obtain the position of the lifting member 30 by other means, such as directly detecting the position of the lifting member 30, or by detecting the position of the driving portion to obtain the position of the battery mounting portion 2. In other embodiments, the detection component may also obtain the position of the battery mount portion 2 in other manners, such as by detecting the position of the driving portion to obtain the position of the battery mount portion 2, or directly detecting the position of the battery mount portion 2.

By applying the power swapping apparatus 100 in any of the embodiments described above to a power swapping station, a power swapping station capable of detecting the position of the driving unit of the lifting device 1 can be obtained. As to how to apply the swapping device 100 to the swapping station, reference may be made to the related art.

Example 2

The detecting component in this embodiment is the same in structure as embodiment 1, and the logic for controlling the driving part to stop moving by the control module is different from embodiment 1.

In this embodiment, when the sliding element 13 of the driving portion drives the follower 42 to move to correspond to one of the fixing elements 41, the fixing element 41 senses the follower 42 and sends an electrical signal to the control module, and the rotating shaft 20 drives the first following point 53 or the second following point 54 on the lifting detection following portion 52 to move to correspond to the position of the lifting detection fixing portion 51, so that the lifting detection fixing portion 51 senses and sends an electrical signal to the control module, that is, the control module sends an electrical signal to the motor after receiving the electrical signals of the fixing element 41 and the lifting detection fixing portion 51 to control the motor to stop moving, so as to ensure that the battery mounting portion moves in place. If the control module does not receive the electrical signal of the lifting detection fixing part 51 within the preset time of the system after receiving the signal of the fixing part 41, or if the control module does not receive the signal of the fixing part 41 within the preset time of the system after receiving the electrical signal of the lifting detection fixing part 51, it indicates that there is a sensor fault, or the driving part has a large transmission error, or the lifting part has a large transmission error, and the control system sends an alarm signal to remind a worker that the lifting device needs to be checked or recalibrated.

Example 3

The stroke detection mechanism 40 of the detection assembly in this embodiment is the same in structure as that of embodiment 1, and includes two fixing members 41 and a follower 42, one fixing member 41 being located on the moving path so as to match a first preset elevating position of the battery mounting portion 2 on the elevating path, and the other fixing member 41 being located on the moving path so as to match a second preset elevating position of the battery mounting portion 2 on the elevating path; the elevating position of the battery mounting portion 2 is obtained by detecting the movement position of the driving portion. The lifting height position of the battery mounting part 2 is fed back through the movement of the driving part, and because the middle part has excessive movement transmission, errors usually exist, and the lifting height position of the battery mounting part 2 is correctly reflected by adding an empirical value.

This embodiment improves the accuracy of reflecting the position of the battery mounting portion by the position of the driving portion by correcting the error in the transmission process.

In the present embodiment, the detection unit does not include the elevating position detection mechanism 50 in embodiment 1, and reflects the elevating position of the battery mounting portion only in the position of the driving portion.

In other embodiments, the stroke detection mechanism 40 in the present embodiment may be employed to obtain the position of the battery mounting portion, while the elevation position detection mechanism 50 in embodiment 1 may be employed to obtain the position of the battery mounting portion. Specifically, no matter whether the sliding member 13 of the driving portion drives the follower 42 to move to correspond to any one of the fixing members 41, so that the fixing member 41 senses the follower 42 and sends an electrical signal to the control module, or the rotating shaft 20 drives the first following point 53 or the second following point 54 on the lifting detection following portion 52 to move to correspond to the position of the lifting detection fixing portion 51, so that the lifting detection fixing portion 51 senses and sends an electrical signal to the control module, and the control module can send an electrical signal to the motor to control the motor to stop moving. That is, the elevation of the battery mounting portion can be accurately controlled even when the stroke detection mechanism 40 or the elevation position detection mechanism 50 fails. Meanwhile, the accuracy of reflecting the position of the battery installation part through the position of the driving part is improved by correcting errors in the transmission process.

Example 4

In the present embodiment, the two ends of the moving path of the sliding member 13 have a first limit position and a second limit position, and the two fixing members 41 are spaced between the first limit position and the second limit position. When the battery mount section 2 moves to the uppermost position or the lowermost position, the follower 42 is located between the two fixing pieces 41.

The driving part drives the follower 42 to move between the two fixing pieces 41, and the follower 42 does not move to the position corresponding to the fixing piece 41 and is sensed by the fixing piece 41, so that the movement path of the battery mounting part 2 can cover the highest position and the lowest position, and the lifting of the battery mounting part 2 is completed. During normal operation of the lifting device 1, the follower 42 is not sensed by the fixing member 41. If the driving portion drives the battery mounting portion 2 to move to the highest position or the lowest position and then move continuously, when the driving portion drives the follower 42 to move continuously to a position corresponding to any one of the fixing pieces 41, the fixing piece 41 can sense the follower 42, the fixing piece 41 sends the sensed signal to the control module to control the movement of the driving portion, so that the driving portion is controlled to stop moving, and the driving portion is prevented from moving continuously to damage the battery mounting portion 2 or other structures of the battery replacement device 100. The two fixing pieces 41 are arranged between the first limit position and the second limit position, and safe movement allowance is reserved for movement of the driving portion, so that the movement safety of the driving portion is improved. The structure in the embodiment can play a stroke protection role.

In other embodiments, the two fixing members 41 may be located at the first limit position and the second limit position, respectively, so that the lifting device 1 is compact.

Further, in the present embodiment, the detecting assembly further includes a lifting position detecting mechanism 50, as shown in fig. 11, the lifting position detecting mechanism 50 includes two lifting detecting fixing portions 51 and two lifting detecting following portions 52, the lifting detecting fixing portions 51 are fixed on the frame 3 through brackets 55, the lifting detecting following portions 52 are connected to the rotating shaft 20 and rotate synchronously with the rotating shaft 20, and the lifting detecting following portions 52 are sensed by the lifting detecting fixing portions 51 to detect the rotating position of the rotating shaft 20.

As shown in fig. 11, the two elevation detection following portions 52 have a first following point 53 and a second following point 54, respectively; the first follow-up point position 53 corresponds to a first preset lifting position, i.e., the highest position, of the battery mounting part 2; the second following point position 54 corresponds to a second preset elevating position, i.e., the lowest position, of the battery mounting portion 2. As shown in fig. 10 and 11, the battery mounting portion 2 is located at the lowest position, and the second following point 54 is located at the position corresponding to the elevation detection fixing portion 51. In the present embodiment, the two lifting detection fixing parts 51 are both hall sensors, and the materials at the first following point 53 and the second following point 54 are both metals that can be sensed by the hall sensors.

Set up two lift detection follow-up portions 52 and correspond with the highest position and the lowest position of the lift route of battery installation department 2 respectively, when battery installation department 2 lifts or descends to target in place, lift detection fixed part 51 just in time can sense first follow-up position 53 or second follow-up position 54, and give control module with the signal transmission who senses, send the stop motion of signal control drive division to the drive division through control module, in order to avoid the drive division to continue to drive the motion of battery installation department 2, lead to the skew preset position of battery installation department 2 or lifting device 1 to damage, improve the stability and the security of lifting device 1.

In this embodiment, the stroke protection function is realized by the position detection of the driving portion, and the accurate position of the lifting of the battery mounting portion is realized by the rotational position detection of the rotating shaft. Both reliability and accuracy. Particularly, the position detection of the driving part used for stroke protection detection is positioned at one end of the power transmission close to the power source, the rotation position detection of the rotating shaft used for accurate position detection of the battery installation part is positioned at the tail end of the power transmission close to the power source, and the rotation position detection are matched to reflect whether the transmission mechanism between the power transmission and the rotating shaft works normally or not.
