[ example 1 ]

Fig. 1-10 illustrate an unlocking assembly and a battery swapping system including the same. The unlocking assembly comprises a locking fitting piece 210 installed on the electric vehicle and an unlocking positioning piece 100 installed on the battery replacement equipment, wherein the locking fitting piece is used for locking or unlocking a locking shaft 550 on the battery pack. Specifically, the unlocking positioning member 100 includes a guide portion 102, and the guide portion 102 is configured to cooperate with the locking fitting 210 to unlock the locking fitting. Locking fitting piece 210 is second grade locking mechanism, provides secondary locking or locking protect function for the battery package through second grade locking mechanism, prevents that the battery package from dropping, improves the security. Wherein, when in the unlocked state, guide 102 has a first height H1 above the bottom surface of lock engagement member 210; locking mating element 210 includes a tongue body 212 and an unlocking portion 212a, where unlocking portion 212a extends vertically downward from tongue body 212 by a second height H2; the first height H1 and the second height H2 are set such that the latch body 212 escapes from the movement path of the lock shaft 550 when the unlocking portion 212a is pushed up by the guide portion 102. Wherein the first height H1, the second height H2 are schematically shown in fig. 3 and fig. 1, respectively.

In the embodiment, the first height H1 and the second height H2 are configured such that when the unlocking portion 212a is jacked up, the bolt body 212 is opened in place and is retracted from the movement path of the lock shaft 550, and the lock shaft 550 can be disengaged from the lock mating member 210, so that when the unlocking positioning member 100 is moved in place, the lock shaft 550 can be disengaged from the lock mating member 210 to be in an unlocked state, thereby improving unlocking reliability.

That is, the configuration of first height H1 and second height H2 enables lock fitting 210 to be unlocked sufficiently to ensure that lock shaft 550 can be disengaged from lock fitting 210 to be unlocked.

In a preferred embodiment, the first height H1 and the second height H2 are in an inversely proportional relationship. On the basis of meeting the compatibility of the whole vehicle space and the power conversion station, if the first height H1 is increased in an allowable range, the second height H2 can be correspondingly reduced. And vice versa. The inverse proportional relationship between the first height H1 and the second height H2 is beneficial to ensure that the lock shaft 550 can be separated from the locking mating member 210 to be in the unlocked state when the unlocking positioning member 100 moves in place, and the economy is good.

In this embodiment, as shown in FIGS. 1-3 and 5-7, locking fitting 210 further includes a lock base 213, lock base 213 having an opening for receiving lock shaft 550 into lock slot 211 and lock slot 211 extending from the opening. The latch body 212 is rotatably connected to the lock base 213 by a rotating shaft 212b, and rotates with respect to the lock base 213 to change between an unlocked state and a locked state. The unlocking positioning member 100 acts on the unlocking portion 212a to open the latch body 212, so as to open the passage of the locking shaft 550 into and out of the locking groove 211. In the locked state, at least part of the latch bolt body 212 extends into the lock slot 211 and is used for blocking the lock shaft 550 from exiting the lock slot 211; in the unlocked state, deadbolt body 212 retracts out of lock slot 112 and opens the passage for lock shaft 550 into and out of lock slot 211.

The lock base 213 has a third height, and the ratio of the first height H1 to the third height H3 is greater than 1.5 and not greater than 3 when the second height H2 is constant. Wherein the third height H3 is schematically shown in fig. 3.

The ratio of the height of the guide portion 102 to the height of the locking mating piece 210 is set in the above range, so that the relative movement stroke between the guide portion 102 and the locking mating piece 210 is increased, the acting time of the guide portion 102 on the unlocking portion 212a is increased, the guide portion 102 and the unlocking portion 212a are in full contact in the unlocking process, the lock tongue body 212 is completely opened, and the unlocking success rate is improved. And under the condition of good economy, the redundancy maximization is realized, the fault-tolerant rate is high, the unlocking reliability is high, and the applicability is high. If the ratio of the height of the guide portion 102 to the height of the locking mating piece 210 is less than 1.5, the relative movement distance between the guide portion and the locking mating piece 210 cannot meet the unlocking requirement, so that the bolt body 212 cannot be opened in place and the movement path of the lock shaft 550 is blocked. If the ratio of the height of the guide portion 102 to the height of the locking fitting 210 is greater than 3, the space between the battery replacement device and the electric vehicle is not allowed, and the battery replacement device has a complicated structure, high cost, and poor economy.

In a preferred embodiment, the first height H1 is 67mm, the second height H2 is 13mm, and the third height H3 is 32.85mm, where the ratio of the first height H1 to the third height H3 is 2.04. In other alternative embodiments, the ratio of the first height H1 to the third height H3 may take any other value within the above-described range.

It should be noted that the ratio of the first height H1 to the third height H3 may be set as large as possible within a permissible range. However, considering that the compatibility between the whole vehicle space and the battery replacement station cannot be too large, if the ratio is too large, on the basis of the unchanged third height H3, the first height H1 is too large, and thus, the interference with the whole vehicle is easy.

The second height H2 cannot be too small in consideration of the strength of the unlocking portion 212a and the like, and in a preferred embodiment, the second height H2 may be set to not less than 8mm.

In the present embodiment, as shown in fig. 1 to 9, the unlocking spacer 100 includes a spacer body 101 and two guiding portions 102, the two guiding portions 102 are disposed on the spacer body 101 at intervals and enclose an accommodating area 31 for accommodating the locking mating member 210 with the spacer body 101, and the top ends of the two guiding portions 102 form an accommodating opening 3. The top end of the guide part 102 is provided with a first guiding inclined surface 91 on the side facing the locking fitting piece 210, and the first guiding inclined surface 91 extends from the side wall of the guide part 102 towards the direction far away from the side wall. That is, the first lead slope 91 is inclined toward a direction away from the receiving port 3 and is disposed obliquely upward. The above structure can play a role of guiding when the locking fitting piece 210 enters the receiving opening 3. When the locking fitting piece 210 has a small error relative to the initial position of the unlocking fitting piece 100, the first guide inclined surface 91 can smoothly guide the locking fitting piece to enter the accommodating port 3, so that the locking fitting piece 100 and the locking fitting piece 210 can be close to each other to match, and the first guide inclined surface 91 is abutted to the unlocking part 212a during unlocking, thereby being beneficial to improving the fault tolerance rate in the unlocking process. The two guide portions 102 and the positioning member body 101 enclose the accommodating area 31 for accommodating the locking mating member 210, so that the positioning accuracy between the unlocking positioning member 100 and the locking mating member 210 can be improved.

In other embodiments, the unlocking fixture 100 may include only one guide portion 102 for the same positioning and unlocking effect.

In the present embodiment, the connection between the first inclined guide surface 91 and the top end of the guide portion 102 is smoothly transitioned, and the transition region is rounded. In the process of guiding the locking mating piece 210 by the top end of the guiding portion 102, the fillet transition area 93 further reduces the requirement for positioning accuracy, and at the same time, can also reduce the wear of the unlocking positioning piece 100 and the locking mating piece 210 to the greatest extent, and prolong the service life of the unlocking positioning piece 100.

In a further preferred embodiment, the top end of the guide portion 102 is provided with second guiding inclined surfaces 92 on both sides adjacent to the first guiding inclined surfaces 91, and the two second guiding inclined surfaces 92 are gradually close to each other along the direction approaching the top surface of the guide portion 102.

Because the battery packs have different sizes and different positions, the second guide inclined plane 92 can prevent the unlocking positioning member 100 from colliding with the battery packs in the process that the unlocking positioning member 100 and the locking matching member 210 approach each other, so that the requirement on the positioning accuracy is greatly reduced. The second guiding inclined surface 92 can also play a guiding role when the unlocking positioning piece 100 extends into a gap between the battery pack and the vehicle body bracket.

Further, as shown in fig. 1 to 8, the unlocking positioning member 100 further includes a detecting element 5 disposed in the accommodating area 31, and the detecting element 5 is used for detecting whether the unlocking positioning member 100 and the locking mating member are matched in place when the battery replacement device replaces the electric vehicle.

Whether the unlocking positioning piece 100 is matched with the locking matching piece in place or not is detected by the detection element 5, namely whether the distance between the unlocking positioning piece 100 and the locking matching piece meets the requirement or not is detected, so that the stable matching state between the unlocking positioning piece 100 and the locking matching piece is achieved before the battery replacement device performs unlocking operation, the battery replacement device is convenient to unlock the locking matching piece on the electric vehicle, and the unlocking success rate is improved.

In particular, in the present embodiment, the accommodating area 31 is disposed above the positioner body 101 and is communicated with the accommodating port 3, and the accommodating area 31 is recessed from the bottom of the accommodating port 3 toward the positioner body 101. With such an arrangement, the detection of the locking fitting piece by the detection element 5 is facilitated, and the influence of the arrangement of the detection element 5 on the matching of the locking fitting piece and the unlocking positioning piece 100 is favorably reduced or avoided.

In this embodiment, locking fitting 210 is a two-stage locking mechanism. As shown in at least fig. 1 to 5, the inner wall 32 of the accommodating area 31 includes at least a bottom wall 322 and a side wall 321, the detection area 4 is disposed at the top of the positioner body 101 at a position corresponding to the travel path of the locking fitting 210, wherein the detection area 4 is recessed downward from the bottom wall 322, the bottom surface of the detection area 4 is lower than the bottom wall 322, and the detection element 5 is disposed in the detection area 4 for measuring the distance between the locking fitting 210 and the detection element 5.

In this embodiment, the top of the detecting element 5 is set not to protrude from the bottom wall 322, so that the detecting element 5 can be prevented from colliding with the lock base 213 of the locking mating piece 210, and thus, when the detecting element 5 fails, the detecting element 5 can be effectively prevented from being damaged due to excessive displacement of the locking mating piece 210, so that the detecting element 5 can be protected, and the stability and reliability of the detection result can be ensured.

When locking fitting 210 enters receiving area 31 from receiving opening 3, detecting element 5 measures the distance between detecting element 5 and locking fitting 210. In this embodiment, detecting element 5 is a hall sensor, and locking mating part 210 is provided with magnetic steel, and in other specific embodiments, locking mating part 210 may not be provided with magnetic steel, but is made of magnetic material. The hall sensor is matched with the locking mating member 210 to obtain the distance between the detecting element 5 and the locking mating member 210 in real time, so that whether the locking mating member 210 and the unlocking mating member 100 reach a stable mating state can be judged.

The detection principle is as follows: when the magnetic steel is close to or far away from the hall sensor, the hall sensor can determine the distance between the magnetic steel and the hall sensor according to the change of the magnetic induction intensity, and accordingly, whether the locking fitting piece 210 and the unlocking positioning piece 100 are already fitted in place is judged.

It will be understood by those skilled in the art that the location and type of the sensing elements 5 are related to the sensing method. For different detection requirements, the skilled person can use different detection methods, also different kinds of detection elements 5, or be arranged at different positions.
