As shown in fig. 2, embodiment 2 discloses another unlocking method, the unlocking method of this embodiment is applied to a battery swapping device, the battery swapping device of this embodiment 2 has the structure of the battery swapping device shown in embodiment 1, as shown in fig. 7 to 8, and further includes a receiving area 310 inside a positioning fork 300, a detection element 301 is disposed in the receiving area 310, the positioning fork 300 is used to cooperate with a matching piece on a vehicle, and in this embodiment, the matching piece is a secondary lock 320, that is, is used to determine whether the positioning fork 300 and the secondary lock 320 on the vehicle cooperate in a height direction.
In other specific embodiments, the matching member may also be a positioning block, the positioning block is a square body and is disposed on a side portion of the battery pack, and when the battery pack is mounted on the vehicle, the positioning block is located between the side portion of the battery pack and the vehicle body bracket.
As shown in fig. 3 to 8, the second-stage lock 320 on the vehicle in this embodiment has a specific structure, the second-stage lock 320 has a second-stage lock slot 121b and a second-stage latch tongue 122b, and the positioning fork 300 acts on the movable end of the second-stage latch tongue 122b, i.e., the extended end of the second-stage latch tongue 122b (the upper end of the second-stage latch tongue 122b in fig. 7), so as to open the passage of the lock shaft 123 of the battery pack into and out of the second-stage lock slot 121 b.
The unlocking method realizes unlocking of the battery pack on the vehicle through the battery replacement equipment, and comprises the following steps:
s0, adjusting the relative position of the battery replacing equipment and the vehicle along the length direction of the vehicle to align an unlocking rod of the unlocking piece with an unlocking block on the locking connecting rod;
specifically, the specific steps of adjusting the relative position of the battery replacement device and the vehicle along the length direction of the vehicle are as follows: the unlocking piece is adjusted along the length direction of the vehicle, the unlocking rod of the unlocking piece is aligned to the unlocking groove in the unlocking block, and the mounting seat at the bottom of the unlocking piece 200 is controlled to move along the sliding rail, so that the unlocking piece 200 is aligned to the unlocking groove 131 in the unlocking block 130.
In other embodiments, the step of adjusting the relative position of the unlocking member along the length direction of the vehicle further comprises: adjusting the position of a vehicle positioning part along the length direction of the vehicle to align a positioning fork with a secondary lock on the vehicle, namely completing the relative position of the battery replacing device and the vehicle along the length direction of the vehicle;
step S0 is a step of performing fine positioning before the formal unlocking is started, and the unlocking unit 200 is aligned with the unlocking block 130 of the lock link 110 and the positioning fork 300 on the vehicle positioning portion and then unlocked after corresponding to the secondary lock 320 on the vehicle, so that the probability of unlocking failure due to the mismatch between the positions of the unlocking rod 201 and the unlocking block 130 and the mismatch between the positions of the positioning fork 300 and the secondary lock 320 during unlocking can be effectively reduced.
S1, adjusting the relative position of the battery replacing equipment and a vehicle in the vertical direction to enable an elastic mechanism of an unlocking piece to be in a compressed state;
the step S1 specifically includes the following steps:
s11: adjusting the positions of a vehicle positioning part of the battery replacing device and the vehicle in the vertical direction, namely lifting the height of the vehicle positioning part and lowering the height of the vehicle, so that the vehicle positioning part and the vehicle are close to each other in the height direction;
in other specific embodiments, the height of the vehicle positioning portion may also be separately increased or decreased, and the purpose of adjusting the position of the vehicle positioning portion and the position of the vehicle in the vertical direction may be achieved, which is not described herein again.
S12: whether the secondary lock and the positioning fork are matched in place or not is detected through the detection element in real time, if yes, the adjustment of the position of the vehicle positioning part and the position of the vehicle in the height direction are stopped, and at the moment, the elastic mechanism of the unlocking piece is in a compression state.
As shown in fig. 3, until the vehicle-positioning portion and the vehicle move to a proper position in the vertical direction, the upper end of the lock release lever 201 abuts against the lock release block 130 of the lock link 110, and the lock release block 130 applies a force to the lock release lever 201 toward the vehicle-positioning portion, thereby pressing down the elastic mechanism to a compressed state. At this time, as shown in fig. 8, the free end of the second-stage latch tongue 122b of the second-stage lock 320 is jacked up by the positioning fork 300.
Since the spring 202 of the unlocking member 200 needs to be in a compressed state during the unlocking process, so that the unlocking member 200 can apply an upward moving acting force to the lock link 110, and the lock link 110 drives the lock tongue to rotate to open the lock slot opening, the relative position (i.e. height difference) of the vehicle and the battery replacement device in height needs to be adjusted. In step S12, whether the secondary lock 320 and the positioning fork 300 are matched in place is detected by the detection element 301, that is, the battery replacement device and the vehicle are matched in place in the vertical direction, at this time, the unlocking piece 200 and the unlocking groove 131 on the unlocking piece 130, and the positioning fork 300 and the secondary lock 320 are matched in place, and after such a state is reached, unlocking is performed again, so that the probability of unlocking failure can be further reduced.
In other specific embodiments, the height of the vehicle positioning portion on the vehicle or the battery replacement device may be adjusted only to realize that the secondary lock 320 on the vehicle is matched with the positioning fork 300 in place, at this time, the unlocking rod 201 abuts against the unlocking block 130 of the lock connecting rod 110, the secondary lock 320 extends into the positioning fork 300, and the positioning fork 300 pushes up the outer end of the secondary lock tongue 122b, which is not described herein again.
S2, the battery replacing equipment moves a lock shaft of a battery pack on the vehicle to a direction far away from the opening of the lock groove for a first preset distance, so that the lock connecting rod drives the lock tongue to open the opening of the lock groove under the action of the elastic mechanism;
when the lock tongue opens the opening of the lock groove, the lock shaft avoids the lock tongue and does not obstruct the rotation of the lock tongue. When the lock shaft 123 moves a first preset distance, the lock shafts 123 in the first-stage lock and the second-stage lock 320 are both far away from the corresponding first-stage lock tongue 122a and second-stage lock tongue 122b, that is, when the lock tongues open the lock groove openings, the lock shafts 123 avoid the lock tongues. Specifically, after the first-stage locking tongue 122a loses the obstruction of the locking shaft 123, the unlocking rod 201 pushes the lock connecting rod 110 to move upward, the first-stage locking tongue 122a is driven to rotate, and then the opening of the first-stage locking groove 121a is opened, so that the unlocking function of the first-stage lock is realized, that is, at this time, the locking shaft 123 can be moved out of the first-stage locking groove 121 a. After the second-stage bolt 122b loses the obstruction of the lock shaft 123, the positioning fork 300 pushes the second-stage bolt 122b to rotate, the second-stage bolt 122b rotates to open the opening of the second-stage lock groove 121b, and at this time, the lock shaft 123 can move out of the second-stage lock groove 121b, so that the unlocking function of the second-stage lock 320 is realized.
In this embodiment, the unlocking member 200 is first used to store energy in the elastic mechanism, and then the locking shaft 123 is moved to a position far away from the latch so that the locking shaft 123 does not obstruct the rotation of the latch, thereby reducing the wear of the locking shaft and the latch during unlocking, and reducing the amount of supporting force required by the elastic mechanism of the unlocking member 200 during unlocking.
And S3, after the battery replacing device moves the lock shaft of the battery pack on the vehicle to a second preset distance towards the direction close to the opening of the lock groove, the battery pack is separated from the vehicle, wherein the second preset distance is larger than the first preset distance.
Specifically, in step S3 of this embodiment, since the lock tongue is already opened, the overall structure has already been unlocked, and therefore, after the battery replacing device moves the lock shaft 123 of the battery pack to the opening direction of the lock slot by the second preset distance, that is, after the second preset distance is moved, the lock shaft 123 is located above the opening of the lock slot, at this time, the lock slot no longer supports the lock shaft 123, and the battery replacing device supports the battery pack to move downward, so that the battery pack is detached from the vehicle. The second preset distance is greater than the first preset distance, that is, compared with a certain position initially abutting against one side of the lock tongue or located in the lock groove, the lock shaft 123 moves in the first preset distance and then moves in the reverse direction, and the second preset distance is greater than the first preset distance, so that the lock shaft 123 continues to move in the direction for a certain distance to reach the opening of the lock groove after passing through the original locking position in the reverse direction.

In the prior art, the unlocking rod 201 directly jacks up the lock connecting rod 110, so that the lock tongue is directly driven to rotate after overcoming the obstruction of the lock shaft 123 to realize the unlocking function, and the lock tongue and the lock shaft 123 are always attached in the process. In the embodiment, since the rotation of the latch bolt is realized after the lock shaft 123 moves away from the opening of the lock slot, compared with the prior art, the latch bolt is firstly separated from the lock shaft 123 in the unlocking process, and is not hindered by the lock shaft 123. Therefore, the unlocking force required by the unlocking method in the embodiment is smaller, and the abrasion of the bolt and the lock shaft 123 due to extrusion can be effectively avoided, so that the service lives of the lock shaft 123 and the locking mechanism are prolonged, and the performance of the locking mechanism after long-time use is ensured.
[ example 3 ]
This embodiment provides an unlocking method, which has substantially the same steps as the unlocking method in embodiment 2. The difference is that in the present embodiment, as shown in fig. 7, a detecting element 301 is provided at the bottom of the housing area 310 of the positioning fork 300 for detecting the distance between the detecting element 301 and the mating member. The step of detecting whether the matching member and the positioning fork 300 are matched in place by the detecting element 301 in the step S12 is specifically:
the detection element 301 obtains the relative distance L between the detection element and the matching element 1 And determining the relative distance L 1 Whether it belongs to presetWithin a range of distances.
Since the size, height and position of the vehicle frame of different vehicle types can be changed, a preset distance range is set by the distance between the detection element 301 and the matching piece. When the distance between the detecting element 301 and the mating member is within a preset distance range, the positioning fork 300 and the mating member are considered to be in a state of being mated in place.
Specifically, in the present embodiment, since the detecting element 301 is disposed toward the mating member, the detecting element 301 serves to detect the distance between itself and the mating member. As the mating member is gradually lowered into the receiving area 310 within the positioning fork 300, the distance between the detection surface of the mating member facing the detection element 301 and the detection element 301 also gradually decreases. When the detecting surface reaches a certain position, that is, the distance between the detecting element 301 and the matching member is within a preset range, it can be considered that the positioning fork 300 and the matching member are in a state of being already matched in place. By the detection method, whether the battery replacement equipment and the vehicle are matched in place in the vertical direction or not can be conveniently judged, and the next unlocking step can be carried out.
Specifically, the detecting element 301 in this embodiment is a hall sensor, and the matching member may be made of a magnetic material or a magnetic structure that can be detected by the detecting element 301 is disposed on the matching member.
[ example 4 ]
This embodiment provides an unlocking method, which has substantially the same steps as the unlocking method in embodiment 2. The difference is that in the present embodiment, the detecting element 301 is disposed on the sidewall of the accommodating area 301 of the positioning fork 300, and the step of detecting whether the matching member and the positioning fork are matched in place by the detecting element 301 in step S12 is specifically:
and acquiring the state of the detection element, and judging whether the detection element is in a triggered state or not.
In this embodiment, the determination of whether the matching member and the positioning fork are matched in place is based on whether the detection element 301 is triggered. The mating piece is lowered into the receiving area 310 in the positioning fork 300 until the detection element is triggered. Since the position where the detecting element 301 is mounted is located on the side of the mating member, once triggered, it represents that the mating member has been lowered to the position where it is fitted, and it can be considered that the positioning fork 300 and the mating member are in the state where they have been fitted. In this case, the detecting element 301 does not need to quantitatively detect a certain distance.
In this embodiment, the detection element is an infrared sensor. In other embodiments, the detecting element may also be a photoelectric sensor, a visual sensor, a laser sensor, etc., which are not described herein.
