[ example 2 ]

As shown in fig. 5, this embodiment provides a power exchanging device with a structure similar to that of embodiment 1, and the overall structure and function of the power exchanging device are substantially the same as those of embodiment 1, except that:

in this embodiment, the detecting element 5 needs to be connected to a control unit in the power exchanging station through a circuit, so that the positioning member body 101 of the positioning member 100 is provided with a wire arrangement hole 7 communicated with the detecting port 4, and the wire arrangement hole 7 is used for a signal wire 8 of the detecting element 5 to pass through. Specifically, there are two wire arranging holes 7, the wire arranging holes 7 are formed on the side wall of the detecting port 4, and the two wire arranging holes 7 are respectively located on two sides of the detecting element 5.

[ example 3 ]

The present embodiment provides a battery swapping device with a structure similar to that of embodiment 1 or 2, where the overall structure and function of the battery swapping device are substantially the same as those of the battery swapping device in embodiment 1 or 2, and the difference is that:

in this embodiment, as shown in fig. 2 and fig. 6, the receiving opening 3 has an opening end for the positioning matching member to enter the receiving opening 3, two first inclined planes 91 are oppositely disposed at the opening end of the inner wall 32 of the receiving opening 3 close to the receiving opening 3, and the two first inclined planes 91 are gradually away from each other along the direction (i.e., the vertical upward direction in fig. 6) in which the second end of the positioning member body 101 points to the first end of the positioning member body 101. The junction between the first inclined surface 91 and the first end of the positioner body 101 (the upper end of the positioner body 101 in fig. 6) is in smooth transition.

Specifically, the upper edge of the inner wall 32 of the receiving opening 3 in the present embodiment, that is, the upper edge of the side wall 321 of the receiving opening 3 of the positioning member 100, has a first inclined surface 91. And the first slope 91 is inclined toward the outside of the receiving port 3 and is disposed obliquely upward. The above-described structure can play a role of guiding when the positioning fitting enters the receiving area 31. The first slope 91 can smoothly guide the positioning fitting into the accommodation area 31 when there is a slight error in the initial position of the positioning fitting.

In this embodiment, the connection between the first inclined surface 91 and the upper end of the positioning element 100 is smoothly transited, and the transition region is rounded. In the process of guiding the positioning matching member at the upper end of the positioning member 100, the fillet transition region 93 further reduces the requirement on the positioning accuracy, and simultaneously can also reduce the abrasion between the positioning member 100 and the positioning matching member to the greatest extent and prolong the service life of the positioning member 100.

In order to make the positioning element 100 enter between the battery pack and the vehicle body bracket 400 more smoothly in the locking and unlocking processes, as shown in fig. 6, the two side surfaces of the upper end of the positioning element 100 close to the first inclined surface 91 in the embodiment are provided with second inclined surfaces 92, the plane where the second inclined surfaces 92 are located is inclined relative to the plane where the positioning element 100 is located, and specifically, the two second inclined surfaces 92 gradually approach each other along the opening direction of the accommodating port 3.

In this embodiment, because the battery pack has different sizes and different battery placement positions, the positioning element 100 and the positioning matching element are in the process of being close to each other, the positioning element 100 may collide with the battery pack or the vehicle body bracket 400, and the second inclined surface 92 can effectively guide the positioning element 100 to avoid the battery pack or the vehicle body bracket 400, so that the requirement on the positioning accuracy is greatly reduced, and meanwhile, the second inclined surface 92 can also play a role in guiding when the positioning element 100 extends into a gap between the battery pack and the vehicle body bracket 400.

[ example 4 ]

The present embodiment provides a battery replacement device similar to any one of embodiments 1 to 3, and the overall structure and function of the battery replacement device are substantially the same as those of any one of embodiments 1 to 3, except that:

the detection element 5 in the present embodiment is provided on the side wall 321 of the accommodation region 31, not on the bottom wall 322. The detecting element 5 is used for measuring whether the positioning matching member and the positioning member 100 are matched in place. Specifically, the detection port 4 is also provided on the side wall 321 and the detection element 5 is completely accommodated in the detection port 4.

The principle of the detecting element 5 of this embodiment for determining whether the positioning matching member and the positioning member are matched in place is as follows:

when the positioning matching member enters the accommodating area 31, the detecting element 5 on the sidewall 321 detects whether the front of the detecting element 5 is shielded by the positioning matching member, if so, the detecting element 5 is triggered, and at this time, the positioning member 100 and the positioning matching member are considered to be matched in place.

In the present embodiment, the detection element 5 is a photosensor, which is an infrared sensor. When the positioning matching piece reaches the preset position, the photoelectric sensor is just shielded, and the photoelectric sensor can obtain that the positioning matching piece is in place according to the judgment. Obviously, in order to achieve the above function, the photoelectric sensor in the present embodiment needs to be disposed at the position of the sidewall 321 of the accommodating area 31 corresponding to the position of the positioning matching member when the positioning matching member is matched with the positioning member 100. Usually, a test is required after installation to verify whether the situation that the positioning matching piece cannot be detected exists, and within an error allowable range, the adjustment can be slightly performed to improve the detection success rate of the photoelectric sensor.

In other embodiments, the detecting element 5 may also be a visual sensor, a laser sensor or other photoelectric sensor, which is not described herein.

The unlocking piece 600 is matched with the unlocking block 510 on the locking connecting rod 520 to drive the first-stage bolt 540 to open or lock the opening of the first-stage locking groove 530, so as to realize unlocking or locking of the first-stage lock 500, the first-stage bolt 540 is connected with the locking connecting rod 520, and the locking connecting rod 520 is jacked up through the top of the unlocking piece 600 to drive the first-stage bolt 540 to unlock. As shown in fig. 2 and 3, the secondary lock 210 includes a secondary lock slot 211 and a secondary latch 212, and an upper end of the positioning member 100 acts on an active end 212a of the secondary latch 212 of the secondary lock 210, i.e., an extended end of the secondary latch 212, to rotate the secondary latch 212 to unlock the lock.

In the locked state, the plurality of lock shafts 550 on the battery pack are correspondingly retained in the primary lock grooves 530 or the secondary lock grooves 211 at corresponding positions.

As shown in fig. 8, the unlocking method in this embodiment includes the following steps:

s1: adjusting the position of the battery replacement equipment relative to the vehicle in the horizontal direction to make the accommodating area 31 of the positioning piece align with a positioning matching piece on the vehicle, wherein the positioning matching piece is a secondary lock 210 in the embodiment;

in the step S1, the position of the vehicle positioning portion 300 relative to the vehicle in the length direction of the electric vehicle is adjusted, so that the unlocking piece 100 on the vehicle positioning portion 300 corresponds to the unlocking block 510 of the primary lock 500, and the accommodating area 31 of the positioning piece 100 on the vehicle positioning portion 300 is aligned with the secondary lock 210 on the vehicle body bracket 400, so as to improve the unlocking success rate of the unlocking mechanism.

S2: and adjusting the position of the battery replacing device relative to the vehicle in the height direction, detecting whether the positioning matching part and the positioning part are matched in place through the detection element, and if so, executing unlocking operation by the battery replacing device.

The step of detecting whether the secondary lock 210 and the positioning element are matched in place by the detection element in step S2 specifically includes:the detecting element obtains the relative distance L between the detecting element and the positioning matching piece ₁ And determining the relative distance L ₁ Whether the distance belongs to the preset distance range.

The unlocking method in the embodiment can ensure that the unlocking process of the primary lock 500 and the secondary lock 210 is started only when the secondary lock 210 and the positioning member 100 are matched in place, thereby achieving the purpose of reliable unlocking.

Further, since the size, height and position of the vehicle frame may vary for different vehicle types, a preset distance range L is required to be set for the distance between the detecting element and the secondary lock 210 ₀ . When the distance L between the sensing element and the secondary lock 210 ₁ Within a predetermined distance range, i.e. L ₁ ≤L ₀ In the meantime, the positioning member 100 and the secondary lock 210 are considered to be in a state of being matched in place, so that the success rate of subsequent unlocking operation is ensured. For example, the preset distance range L ₀ Is 10mm, the detecting element continuously detects the distance L between the detecting element and the secondary lock 210 in the process that the secondary lock 210 and the positioning element 100 are continuously close to each other ₁ And real-time judging L ₀ And L ₁ The magnitude relation of (a), L acquired by the detecting element at a certain time ₁ =9.5mm, and the first judgment gave L ₁ ≤L ₀ As a result, it is considered that the secondary lock 210 is engaged with the positioning member 100, and the adjustment of the positions of the secondary lock 210 and the positioning member 100 in the height direction is stopped, and the battery pack is unlocked.

Further, as shown in fig. 8, in this embodiment, the unlocking operation in step S2 includes the following steps:

s31: the battery replacing device drives the battery pack to move a first distance towards the direction away from the opening of the first-stage locking groove 530, so that a gap exists between the first-stage locking bolt 540 and the locking shaft 550 of the battery pack;

s32: after the battery pack is driven by the battery replacing equipment to move a second distance towards the opening direction close to the first locking groove, the battery pack falls off from the vehicle.

Further, after the battery replacing device in step S31 drives the battery pack to move a first distance in the direction away from the opening of the primary locking groove 530, the method further includes:

s311: the unlocking member 600 pushes up the locking link 520, and the locking link 520 drives the first-stage latch tongue 540 to move and open the opening of the first-stage latch groove 530.

In this embodiment, before unlocking, the battery replacement device first drives the battery pack to move a first distance toward the opening far away from the first-stage locking groove 530 through step S31, that is, the locking shaft 550 of the battery pack is pre-pushed, so that the locking shaft 550 and the first-stage locking tongue 540 on the battery pack are separated, and the battery pack and the first-stage locking tongue 540 are still in an abutting state to prevent abrasion during unlocking. Then, in step S311, since the unlocking member 600 has already jacked up the lock link 520 at this time, the first-stage latch 540 loses the force of the lock shaft 550 blocking its rotation after passing through step S31, and then rotates upward, opening the first-stage lock groove 530, and finally, after the battery replacement device drives the battery pack to move a second distance toward the opening of the first-stage lock groove 530 through step S32, at this time, the lock shaft 550 of the battery pack moves above the opening of the first-stage lock groove 530, and since the first-stage lock groove 530 no longer provides a supporting force for the lock shaft 550, the battery pack falls off from the vehicle under the action of gravity. And separating the battery pack to be unlocked from the vehicle to finish the whole unlocking process. The unlocking process of the secondary lock 210 and the keeper 100 is identical to the unlocking process of the primary lock 500 and the unlocking member 600.

In this embodiment, the unlocking member 600 includes an unlocking rod and a spring, which is compressed in a direction opposite to a direction in which the locking link 520 is pushed up. Based on the above arrangement, the spring is always in a compressed state in the process of jacking up the lock link 520 by the unlocking jack.

Further, when the detection element detects that the positioning matching piece and the positioning piece are matched in place in the step S2, the unlocking ejector rod is in a pressed state.

That is, the unlocking plunger has been advanced into a stressed state before the keeper 100 and secondary lock 210 are engaged. Therefore, before unlocking, the unlocking mandril is compressed to store energy, so that the unlocking success rate is ensured, and meanwhile, abrasion between the first-stage bolt 540 and the lock shaft 550 and between the second-stage bolt 212 and the lock shaft 550 can be avoided.
