Detachable battery mechanism and multi-functional battery replacement equipment including the same, and battery replacement station

Abstract

The present invention provides a detachment mechanism and a multifunctional battery exchange device and battery exchange station including the same. The detachment mechanism is used to attach and detach a battery pack locked up by a lock-up mechanism. The detachment mechanism includes an upper plate and a first positioning mechanism. The first positioning mechanism is foldably attached to the upper plate and can be switched between a vertical state and a horizontal state. The first positioning mechanism is used to position the battery pack when in the vertical state and thereby move the battery pack via the upper plate. If the dimension of the battery pack along the direction of the first positioning mechanism becomes large or the height requirement of the detachment mechanism is limited, the first positioning mechanism can be hidden by switching it to the horizontal state, allowing the first positioning mechanism to be applied to battery packs of different dimensions and operating environments with different height requirements. When the detachment mechanism is applied to a multifunctional battery exchange device, hiding the first positioning mechanism can prevent the first positioning mechanism from affecting the attachment and detachment operations of other detachment mechanisms.

Description

[Technical Field]

[0001] <Cross-Reference to Related Applications> This application claims the priority of Chinese patent applications 2020104534817 and 2021203737848 with a filing date of May 25, 2020. This application incorporates the full text of the above-mentioned Chinese patent application by reference.

[0002] The present invention relates to the field of battery swapping, and in particular to an attachment and detachment mechanism, a multi-functional battery swapping device including the same, and a battery swapping station. [Background Art]

[0003] With the rapid development of new energy electric vehicles, quick battery-swap electric vehicles have emerged. Such vehicles eliminate the need to wait for hours for the battery to be charged, and only require removing the battery with insufficient power from the vehicle and reinstalling a fully charged battery. As places providing quick battery swap services for electric vehicles, battery swapping stations have been constructed and operated on a large scale across the country.

[0004] However, current battery swapping stations are custom-made according to the vehicle models and battery pack specifications of each automaker, and different automakers adopt different locking methods for battery packs. As a result, one battery swapping station can only swap battery packs of one specification and with the same locking method, which greatly limits the development prospect of battery swapping stations.

[0005] Conventional battery swapping stations can only swap battery packs of one size and specification, and therefore the swapping mechanism used to attach and detach battery packs in these stations is also specifically designed for one size and specification of battery pack. The swapping mechanism includes a positioning fork used to position the battery pack. The engagement of the positioning fork with the battery pack fixes the relative position of the battery pack to the battery swapping equipment, and then moves the battery pack to enable battery pack replacement. To ensure the accuracy of the engagement between the positioning fork and the battery pack and to increase the reliability of battery pack movement, the size of the positioning fork is designed based on the size of the battery pack. If the height dimension of the battery pack is large, it may cause collision between the positioning fork and the battery pack, and if the height dimension of the battery pack is small, the positioning fork may not be able to position the battery pack. [Overview of the Initiative]

[0006] The technical problem that the present invention aims to solve is to provide a detachment mechanism, a multi-functional battery replacement equipment including the same, and a battery replacement station in order to overcome the problem in the prior art where the height dimension of the battery pack is large and causes collision between the positioning fork and the battery pack.

[0009] In this proposed technology, when the detachment mechanism is in operation, the first positioning mechanism is in a vertical position and can fork the battery pack. Furthermore, the upper plate moves the battery pack, enabling unlocking and detachment of the battery pack. If the dimensions of the battery pack along the direction of the first positioning mechanism become large, or if the height requirements of the detachment mechanism are limited, the first positioning mechanism can be hidden by switching it to a horizontal position, allowing the first positioning mechanism to be applied to battery packs of different dimensions and operating environments with different height requirements. At the same time, when other detachment mechanisms are in operation, the structure of the above-mentioned detachment mechanism is configured to hide the first positioning mechanism, so that the first positioning mechanism does not affect the battery pack detachment operation of other detachment mechanisms.

The structure of the detachment mechanism allows for situations where the dimensions of the battery pack along the direction of the first positioning mechanism are large, or where the height requirements for the detachment mechanism are limited. Ejector rod Hide it, Ejector rod It can be adapted to battery packs of different dimensions and operating environments with different height requirements, and Ejector rod This ensures that it does not interfere with the battery pack attachment and detachment operation of other attachment / detachment mechanisms.

[0017] Preferably, the second positioning mechanism is foldably mounted on the lower plate to switch between a vertical and a horizontal position.

[0018] In this proposed technology, the structure of the detachment mechanism allows for the second positioning mechanism to be concealed if the dimensions of the battery pack along the direction of the first positioning mechanism become large, or if there are limitations on the height requirements of the detachment mechanism. This allows the second positioning mechanism to be applied to battery packs of different dimensions and operating environments with different height requirements, and also prevents the second positioning mechanism from affecting the battery pack detachment operation of other detachment mechanisms.

Furthermore, the upper plate moves the battery pack, enabling the unlocking and detachment of the battery pack. If the dimensions of the battery pack along the direction of the first positioning mechanism become large, or if the height requirements of the detachment mechanism are limited, the first positioning mechanism can be hidden by switching it to a horizontal position, allowing the first positioning mechanism to be applied to battery packs of different dimensions and operating environments with different height requirements.

[Modes for carrying out the invention]

[0069] The present invention will be further described below through examples, but the present invention is not limited thereto to the scope of the above examples.

[0070] <Example 1> When different types of battery packs are installed with electric vehicles or charging equipment, the lock-up mechanisms used are generally different. As shown in Figure 1, the present invention provides a multifunctional battery exchange device used for attaching and detaching battery packs locked up by different lock-up mechanisms. Specifically, the battery exchange device includes a first attachment / detachment mechanism 1 and a second attachment / detachment mechanism 2, where the first attachment / detachment mechanism 1 corresponds to a first lock-up mechanism and the second attachment / detachment mechanism 2 corresponds to a second lock-up mechanism, the first attachment / detachment mechanism 1 is used to attach and detach a first battery pack locked up by the first lock-up mechanism, and the second attachment / detachment mechanism 2 is used to attach and detach a second battery pack locked up by the second lock-up mechanism.

[0071] By simultaneously arranging a first attachment / detachment mechanism 1 and a second attachment / detachment mechanism 2 in a single battery exchange device, the device can be used simultaneously for attaching and detaching two types of battery packs, thereby increasing the compatibility of the battery exchange device, improving battery exchange efficiency, increasing the compatibility of battery exchange stations, and reducing the manufacturing cost of battery exchange stations. Different types of battery packs include not only differences in specifications and size of the battery packs, but also differences in the type of lock-up mechanism of the battery pack on the corresponding electric vehicle.

[0072] Here, the battery replacement equipment further includes a control mechanism, which is used to receive the type of lock-up mechanism of the battery pack to be attached or detached, and is also used to control the corresponding attachment / detachment mechanism to complete the attachment or detachment of the battery pack. For example, if the control mechanism receives that the type of lock-up mechanism of the battery pack to be attached or detached is a first lock-up mechanism, i.e., the battery pack is a first battery pack, the control mechanism controls the first attachment / detachment mechanism 1 to unlock or lock up the first lock-up mechanism, allowing the first battery pack to complete removal or installation. If the control mechanism receives that the type of lock-up mechanism of the battery pack to be attached or detached is a second lock-up mechanism, the control mechanism controls the second attachment / detachment mechanism 2 to unlock or lock up the second lock-up mechanism, allowing the second battery pack to complete removal or installation.

[0073] As shown in Figure 1, the battery replacement equipment further includes a base 3, and the first detachment mechanism 1 and the second detachment mechanism 2 are detachably attached to the base 3. The detachable connection between the first detachment mechanism 1 and the second detachment mechanism 2 and the base 3 allows the battery replacement equipment to be fitted with either the first detachment mechanism 1 or the second detachment mechanism 2 individually, enabling the battery replacement equipment to be used for the attachment and detachment of either the first or second battery pack individually. The battery replacement equipment can also be fitted with both the first detachment mechanism 1 and the second detachment mechanism 2 simultaneously, enabling the battery replacement equipment to handle both the attachment and detachment of the first and second battery packs.

[0074] As shown in Figure 1, the positions of the first detachment mechanism 1 and the second detachment mechanism 2 on the base 3 are determined relatively. The area where the second detachment mechanism 2 is located relative to the first detachment mechanism 1 is a avoidance area, meaning that the second detachment mechanism 2 does not affect the battery pack detachment operation of the first detachment mechanism 1. The area where the first detachment mechanism 1 is located relative to the second detachment mechanism 2 is a avoidance area, meaning that the first detachment mechanism 1 does not affect the battery pack detachment operation of the second detachment mechanism 2.

[0075] In other embodiments, there may be multiple attachment / detachment mechanisms, which correspond to battery packs locked up by multiple different lock-up mechanisms. The number of attachment / detachment mechanisms is determined according to the number of lock-up mechanisms required to be incorporated into the battery replacement equipment.

[0076] The above multi-functional battery exchange equipment is applied to a battery exchange station so that the battery exchange station can handle the attachment and detachment of multiple types of battery packs. The battery exchange station to which the above multi-functional battery exchange equipment is applied is shown in Figure 2, and the battery exchange station includes a battery bin 100, a first battery exchange device 200, and a second battery exchange device 300, where the battery bin 100 houses a first battery pack corresponding to a first lock-up mechanism and a second battery pack corresponding to a second lock-up mechanism. The first battery exchange device 200 and the second battery exchange device 300 are multi-functional battery exchange equipment, the first battery exchange device 200 is used to remove a battery pack with insufficient power from an electric vehicle 400, and the second battery exchange device 300 is used to install a fully charged battery pack into the electric vehicle 400.

[0077] The first battery exchange equipment 200 and the second battery exchange equipment 300 are installed as a multi-functional battery exchange equipment, allowing the first battery exchange equipment 200 and the second battery exchange equipment 300 to be used for exchanging either the first or second battery pack. If the battery pack to be replaced is the first battery pack, the first battery exchange equipment 200 can remove the underpowered first battery pack from the electric vehicle 400 while the second battery exchange equipment 300 can take the fully charged first battery pack from the battery bin 100 and wait. After the first battery exchange equipment 200 has finished removing the first battery pack, the second battery exchange equipment 300 can immediately install the first battery pack into the electric vehicle 400. If the battery pack to be replaced is the second battery pack, the first battery exchange equipment 200 can remove the underpowered second battery pack from the electric vehicle 400 while the second battery exchange equipment 300 can take the fully charged second battery pack from the battery bin 100 and wait. After the first battery exchange equipment 200 completes the removal of the second battery pack, the second battery exchange equipment 300 immediately installs the second battery pack into the electric vehicle 400. In this way, when the first battery exchange equipment 200 and the second battery exchange equipment 300 can handle the exchange of two types of battery packs, the battery exchange efficiency can be greatly improved.

[0078] To accommodate multiple types of battery packs at the battery exchange station, the first battery exchange equipment 200 and the second battery exchange equipment 300 may be provided with multiple attachment / detachment mechanisms.

[0079] <Example 2> The structure of the multi-functional battery exchange equipment in Example 2 is almost the same as that of Example 1, but differs in that the position between the first attachment / detachment mechanism 1 and the second attachment / detachment mechanism 2 can be adjusted by an avoidance mechanism. That is, the battery exchange equipment is further provided with an avoidance mechanism, which moves idle attachment / detachment mechanisms to an avoidance position, and attachment / detachment mechanisms located in the avoidance position do not affect the battery pack attachment / detachment operation of the other attachment / detachment mechanisms.

[0080] In actual detachment and installation situations, the first detachment mechanism 1 and the second detachment mechanism 2 may interfere with each other during the detachment process. In this case, when the first detachment mechanism 1 performs the detachment and installation operation of the battery pack, the second detachment mechanism 2 needs to move to a position that avoids interfering with the detachment and installation operation of the first detachment mechanism 1. On the other hand, when the second detachment mechanism 2 performs the detachment and installation operation of the battery pack, the first detachment mechanism 1 needs to move to a position that avoids interfering with the detachment and installation operation of the second detachment mechanism 2.

[0081] The avoidance mechanism of this embodiment is as shown in Figure 3. The avoidance mechanism 4 includes a reversing body 41 and a rotating shaft 42. The reversing body 41 rotates around the axis of the rotating shaft 42 to achieve reversal. The reversing body 41 is provided with a first mounting surface 411 and a second mounting surface 412 along the circumferential direction. The first detachable mechanism 1 is attached to the first mounting surface 411, and the second detachable mechanism 2 is attached to the second mounting surface 412. During the reversal process, the reversing body 41 rotates the idle detachable mechanism to an avoidance position.

[0082] For example, when attaching or detaching a battery pack using the first attachment / detachment mechanism 1, the inverting body 41 inverts, causing the first attachment / detachment mechanism 1 to be in the attachment / detachment position and the second attachment / detachment mechanism 2 to be in the avoidance position. The first attachment / detachment mechanism 1, in the attachment / detachment position, can then attach or detach the battery pack, while the second attachment / detachment mechanism 2, in the avoidance position, does not affect the attachment / detachment operation of the first attachment / detachment mechanism 1. Also, for example, when attaching or detaching a battery pack using the second attachment / detachment mechanism 2, the inverting body 41 inverts, causing the second attachment / detachment mechanism 2 to be in the attachment / detachment position and the first attachment / detachment mechanism 1 to be in the avoidance position. The second attachment / detachment mechanism 2, in the attachment / detachment position, can then attach or detach the battery pack, while the first attachment / detachment mechanism 1, in the avoidance position, does not affect the attachment / detachment operation of the second attachment / detachment mechanism 2.

[0083] In other embodiments, the inverting body may have several mounting surfaces, and each detachment mechanism may be mounted separately on one mounting surface, with the inverting body rotating idle detachment mechanisms to a position that avoids them during the inverting process. The number of detachment mechanisms is determined according to the number of corresponding lock-up mechanisms required for the battery exchange equipment.

[0084] <Example 3> The structure of the multi-functional battery exchange equipment in Example 3 is almost the same as that of Example 1, but the differences are as follows.

[0085] As shown in Figure 4, the first attachment / detachment mechanism 1 consists of an upper plate 11, a lower plate 12, a first positioning mechanism, and Ejector rod Including 14, the upper plate 11 is located above the lower plate 12, and the upper plate 11 is movable relative to the lower plate 12. The first positioning mechanism in this embodiment is a first positioning fork 13, which is provided on the upper plate 11, and the first positioning fork 13 is used to position the battery pack. Ejector rod 14 is provided on the lower plate 12, Ejector rod 14 is used to unlock the first lock-up mechanism 50.

[0086] Figure 5 shows the first lock-up mechanism 50 corresponding to the first detachment mechanism 1, which includes a lock link 501, a lock base 502, and a lock tongue 503. The lock base 502 has a lock slot 504 formed therein, the lock tongue 503 is located within the lock slot 504, and the lock link 501 can retract the lock tongue 503 outside the lock slot 504.

[0087] When unlocking the first battery pack, Ejector rod 14 presses against the unlocked position 505 of the lock link 501, moving the lock link 501 and causing the locking tab 503 to retract outside the lock slot 504. The first positioning fork 13 forks the first battery pack, and the upper plate 11 moves the first battery pack, causing the locking shaft of the first battery pack to move out of the lock slot 504, thereby unlocking the first battery pack. When locking up the first battery pack, Ejector rod 14 moves to a position where it does not contact the lock link 501, the first positioning fork 13 forks the first battery pack, the upper plate 11 moves the first battery pack so that the lock shaft of the first battery pack enters the lock slot 504, thereby achieving lock-up.

[0088] The first detachment mechanism 1 further includes a second positioning mechanism, the second positioning mechanism in this embodiment being a second positioning fork 15, the second positioning fork 15 being fixed to a lower plate, the second positioning fork 15 engaging with a positioning block on the electric vehicle, and enabling the lower plate to relatively fix its position with respect to the electric vehicle when unlocking or locking up the first battery pack.

[0089] The specific structure of the first lock-up mechanism 50 shown in Figure 5 is a typical example of the lock-up end of the first lock-up mechanism. However, in addition to the structure in Figure 5, it can be understood that the upper plate 11 and the lower plate 12 can lock up or unlock other parts that need to move relative to each other, namely other non-rotating lock-up mechanisms such as snap-type or staggered tooth-type lock-up structures. It is only necessary to design the relative movement of the upper plate 11 and the lower plate 12 to match the lock-up or unlock-up direction of the first lock-up mechanism 50.

[0090] As shown in Figures 4, 6, and 7, the battery replacement equipment further includes a fixing plate 5, and the second detachment mechanism 2 is fixed to the surface of the fixing plate 5 relative to the lower plate 12. The fixing plate 5 can be inverted relative to the upper plate 11, allowing the second detachment mechanism 2 to move to the detachment position or the avoidance position. As shown in Figure 6, the fixing plate 5 is inverted above the upper plate 11, and the second detachment mechanism 2 is in the detachment position, positioned above the fixing plate 5, and the second detachment mechanism 2 is capable of detaching a battery pack having a second lock-up mechanism. As shown in Figure 7, the fixing plate 5 is inverted parallel to the upper plate 11, and the second detachment mechanism 2 is in the avoidance position, positioned below the fixing plate 5, and the second detachment mechanism 2 does not affect the battery pack detachment operation of the first detachment mechanism 1.

[0091] As shown in Figure 8, the second lock-up mechanism 2 includes a rotating part 21 and a rotation control mechanism 22. The second lock-up mechanism is provided with a lock-up end that engages with the rotating part 21, and the rotating part 21 is used to rotate the lock-up end of the second lock-up mechanism for attachment and detachment. The rotation control mechanism 22 is used to control the rotation of the rotating part 21 so that the rotating part 21 can rotate the lock-up end and achieve attachment and detachment of the second lock-up mechanism.

[0092] Here, the rotation control mechanism 22 includes a motor 221 and a reduction gear 222, and the output of the motor 221 can be input directly or indirectly to the reduction gear 222. For example, a connecting shaft (not shown) provided on the motor 221 can extend to a coupling (not shown) in the reduction gear 222, thereby enabling the connection between the motor 221 and the reduction gear 222. The reduction gear 222 changes the rotational speed of the motor 221, and then the reduction gear 222 directly or indirectly drives the rotating part 21 to tighten or loosen the lock-up end of the second lock-up mechanism, thereby enabling the removal or installation of the second battery pack. A bolt is a typical example of the lock-up end of the second lock-up mechanism. However, it can be understood that the rotating part 21 can be used to screw in any member that requires rotational operation other than a bolt, and it is only necessary to design the rotating part 21 to match the shape of the lock-up end of the second lock-up mechanism.

[0093] Here, the upper plate 11 is provided with a hidden groove. Ejector rod Part 14 is rotatable within a concealed groove. Ejector rod If 14 is located within a hidden groove, Ejector rod 14 does not affect the battery pack attachment / detachment operation of the second attachment / detachment mechanism 2.

[0094] Here, the first positioning fork 13 is also foldably attached to the upper plate 11, and when the first positioning fork 13 is folded from a vertical to a horizontal position, the first positioning fork 13 does not affect the battery pack attachment and detachment operation of the second attachment / detachment mechanism 2.

[0095] Here, the second positioning fork 15 is also foldably attached to the lower plate 12, and when the second positioning fork 15 is folded from a vertical to a horizontal position, the second positioning fork 15 does not affect the battery pack attachment and detachment operation of the second attachment / detachment mechanism 2.

[0096] The first positioning fork 13, the second positioning fork 15 and Ejector rodThe choice of concealment method 14 depends on the actual need for the detachment space required for the second detachment mechanism 2. If the multi-functional battery replacement equipment is equipped with a detachment mechanism other than the second detachment mechanism 2, the first positioning fork 13, the second positioning fork 15 and Ejector rod Item 14 can also be hidden in other ways so as not to interfere with the battery pack removal and installation operation of other detachable mechanisms.

[0097] The first and second lock-up mechanisms in this embodiment were described using Chinese patent applications numbered 2016110412204 and 2017112736024 as examples. However, the two types of lock-up mechanisms in the multi-functional battery exchange equipment of the present invention are not limited to the specific structures in the prior art described above, but can also be applied to other types of battery lock-up structures.

[0098] <Example 4> The structure of the multi-functional battery exchange equipment in Example 4 is almost the same as that of Example 3, but the differences are as follows.

[0099] As shown in Figure 9, the edge of the upper plate 11 forms a housing space 111 for housing the fixing plate 5, and a slide bar 112 is provided in the housing space 111 like a sleeve, and the fixing plate 5 is sleeved on the slide bar 112. The fixing plate 5 slides on the slide bar 112, allowing the fixing plate 5 to reciprocate relative to the upper plate 11. When the fixing plate 5 extends away from the upper plate 11, the second detachment mechanism 2 is in the detachment position, and the second detachment mechanism 2 can detach a battery pack having a second lock-up mechanism. When the fixing plate 5 retracts close to the upper plate 11, the second detachment mechanism 2 is in the avoidance position, and the second detachment mechanism 2 does not affect the battery pack detachment operation of the first detachment mechanism 1.

[0100] With the above structure, it is also possible to switch the position of the second attachment / detachment mechanism 2 in order to meet the need to avoid the battery pack attachment / detachment operation by the first attachment / detachment mechanism 1.

[0101] In addition to the avoidance mechanisms described in Examples 3 and 4, an avoidance mechanism can be designed based on the actual attachment / detachment position and avoidance position of the second attachment / detachment mechanism 2. The avoidance mechanism is within the scope of protection required by the present invention as long as it can achieve the function of moving the second attachment / detachment mechanism 2 to the attachment / detachment position or the avoidance position.

[0102] <Example 5> The structure of the multi-functional battery exchange equipment in Example 5 is almost the same as that of Example 3, but the differences are as follows.

[0103] As shown in Figure 10, the battery replacement equipment includes a replacement tray 6 that is detachably attached to the upper plate 11, and the second attachment / detachment mechanism 2 is attached to the replacement tray 6. When it is necessary to attach or detach the battery pack using the second attachment / detachment mechanism 2, the replacement tray 6 is attached to the upper plate 11, allowing the battery pack with the second lock-up mechanism to be attached or detached. When it is not necessary to attach or detach the battery pack using the second attachment / detachment mechanism 2, the replacement tray 6 is removed, and the battery pack attachment / detachment operation of the first attachment / detachment mechanism 1 is not affected.

[0104] The first detachable mechanism 1 further includes a docking mechanism 16, which is attached to the upper plate 11, and the replacement tray 6 is attached to the docking mechanism 16. Here, the docking mechanism 16 further includes an electrical interface, which is used to electrically connect to the electrical interface of the second detachable mechanism 2. The docking mechanism 16 is used to secure the replacement tray 6, and at the same time, the electrical interface of the docking mechanism 16 is also electrically connected to the electrical interface of the second detachable mechanism 2, supplying power to the second detachable mechanism 2.

[0105] <Example 6> The structure of the battery replacement equipment in Embodiment 6 is substantially the same as that of Embodiment 3. This embodiment provides a specific structure for a foldable positioning mechanism, and the foldable first positioning mechanism (first positioning fork 13) and second positioning mechanism (second positioning fork 15) in the other embodiments described above can refer to the positioning mechanism in this embodiment.

[0106] As shown in Figures 11 to 15, this embodiment provides a reversible and foldable positioning mechanism structure such that the positioning mechanism can switch between a vertical and a horizontal state, that is, the positioning mechanism can be folded from a vertical state to a horizontal state, or inverted from a horizontal state to a vertical state. When the positioning mechanism is in the vertical state, it can properly position the battery pack. When the positioning mechanism is in the horizontal state, it can avoid interfering with the positioning of the battery pack by other positioning devices, and can avoid interfering with the attachment and detachment of the battery pack by other attachment and detachment mechanisms.

[0107] As shown in Figures 11 to 15, the positioning mechanism includes a positioning mechanism body 61 and a reversing mechanism for folding the positioning mechanism body 61. The positioning mechanism body 61 is used to contact the battery pack and position the battery pack, and the reversing mechanism is connected to the positioning mechanism body 61 and is used to rotate the positioning mechanism body 61 so that it switches between a vertical and a horizontal position.

[0108] As shown in Figures 13, 16, and 17, the reversing mechanism includes a drive member 62 and a rotating shaft 63. The drive member 62 is connected to the rotating shaft 63 and used to rotationally drive the rotating shaft 63. The rotating shaft 63 is connected to the positioning mechanism body 61 and used to rotationally drive the positioning mechanism body 61 to switch between a vertical and a horizontal positioning mechanism body 61. In this embodiment, the rotating shaft 63 and the positioning mechanism body 61 are fixedly connected by a connecting member. Specifically, a rotating shaft connection hole 611 is provided at the lower end of the positioning mechanism body 61, with both ends passing through it, and the rotating shaft 63 passes through the rotating shaft connection hole 611. The reversal mechanism further includes a connecting member connected between the rotating shaft 63 and the positioning mechanism, the connecting member in this embodiment being a pinky key 64, the rotating shaft 63 being provided with a first keyway 631 for positioning a portion of the pinky key 64, and a second keyway 612 for positioning the other portion of the pinky key 64 at a corresponding position in the rotating shaft connection hole 611, the first keyway 631 engaging with the second keyway 612 to restrict the movement of the pinky key 64 in each direction, thereby fixing the position of the pinky key 64 relative to the rotating shaft 63 and the positioning mechanism body 61. In the process of the rotating shaft 63 rotating, the pinky key 64, which is fixed relative to it, is driven to rotate synchronously, and further the positioning mechanism body 61 connected to the pinky key 64 is driven to reverse direction.

[0109] In other alternative embodiments, the rotating shaft 63 and the positioning mechanism body 61 can be fixedly connected by selecting other connecting members capable of achieving the above functions, or the connection between the rotating shaft 63 and the positioning mechanism body 61 can be realized in other ways, for example, the rotating shaft 63 and the positioning mechanism body 61 can be directly fixedly connected, and such direct fixed connection includes forms such as integral molding and welding. In this embodiment, a pinky 64 is selected as the connecting member for connecting the rotating shaft 63 and the positioning mechanism body 61, which has a simple structure, is easy to install, and can improve assembly efficiency. By fixedly connecting the rotating shaft 63 and the positioning mechanism body 61, the positions of the rotating shaft 63 and the positioning mechanism body 61 are fixed relative to each other, ensuring that the positioning mechanism body 61 can rotate synchronously following the rotating shaft 63, and improving the reliability of the reversal of the positioning mechanism body 61.

[0110] In this embodiment, the drive member 62 is a rotary motor, which can directly rotate the rotating shaft 63. In other alternative embodiments, the drive member 62 may be a different structure capable of rotating the rotating shaft 63.

[0111] As shown in Figure 13, the inversion mechanism further includes at least one position detection device, which is used to ensure the reliability of the adjustment of the positioning mechanism body 61 to a predetermined position and to ensure the accuracy of the positioning mechanism in positioning the battery pack by detecting the position of the positioning mechanism body 61 and determining whether the positioning mechanism body 61 is inverted to a vertical or horizontal position. In this embodiment, there are two position detection devices, but in other alternative embodiments, there may be one or more position detection devices.

[0112] Specifically, as shown in Figures 11 and 14, the position detection device in this embodiment includes a vertical sensor 651 for detecting whether the positioning mechanism body 61 is inverted to a vertical position, and a horizontal sensor 652 for detecting whether the positioning mechanism body 61 is inverted to a horizontal position. Both the vertical sensor 651 and the horizontal sensor 652 in this embodiment are photoelectric sensors, and photoelectric sensors are non-contact sensors. The positioning mechanism body 61 does not interfere with the vertical sensor 651 and the horizontal sensor 652 during the rotation process, ensuring the reliability of the inversion and folding of the positioning mechanism body 61. In addition, photoelectric sensors have a simple structure, a short response time, are easy to control and highly reliable, can identify the position of the positioning mechanism body 61 in a timely manner, and can improve the reliability of adjusting the position of the positioning mechanism body 61 to a predetermined position. In other alternative embodiments, the vertical sensor 651 and the horizontal sensor 652 can be replaced with other position detection devices that can achieve the above functions, and the vertical sensor 651 and the horizontal sensor 652 can be selected with the same or different structures.

[0113] The folding process of the positioning mechanism will be briefly explained below, based on the specific structure of the positioning mechanism described above.

[0114] As shown in Figure 16, during the process of folding the positioning mechanism body 61 from a vertical to a horizontal position, the drive member 62 rotates the rotating shaft 63, which in turn rotates the connected pin key 64 in synchronous motion, further folding the positioning mechanism body 61 which is fitted with the pin key 64. When the horizontal sensor 652 detects the positioning mechanism body 61, the drive member 62 stops rotating the rotating shaft 63.

[0115] As shown in Figure 17, during the process of folding the positioning mechanism body 61 from a horizontal to a vertical position, the drive member 62 rotates the rotation shaft 63 in the opposite direction, the rotation shaft 63 rotates the connected pin key 64 synchronously, and further inverts the positioning mechanism body 61 which is fitted with the pin key 64. When the vertical sensor 651 detects the positioning mechanism body 61, the drive member 62 stops rotating the rotation shaft 63.

[0116] As shown in Figure 13, the reversal mechanism further includes a connecting base 66, a bush 67, a bearing 68, a reversal base 69, and a fixing bracket 610. The drive member 62, the connecting base 66, and the reversal base 69 are sequentially connected along the axial direction of the rotating shaft 63, and the rotating shaft 63 is connected to the drive member 62 by passing through the connecting base 66 and the reversal base 69. The connecting base 66 and the reversal base 69 support the rotating shaft 63, ensuring that the rotating shaft 63 can rotate stably. The bush 67 is sleeved on the outside of the rotating shaft 63, and the bush 67 is connected to the rotating shaft 63 via a bolt 620, protecting the rotating shaft 63 and reducing wear on the rotating shaft 63. The rotating shaft 63 is fixed to the reversal base 69 via a bearing 68, and also enables rotation relative to the reversal base 69. The vertical sensor 651 and the horizontal sensor 652 are mounted on a fixed bracket 610, which is fixed to the inversion base 69, and the fixed bracket 610 serves to support the vertical sensor 651 and the horizontal sensor 652. The vertical sensor 651 and the horizontal sensor 652 remain stationary relative to the position of the inversion base 69 to ensure accuracy of position detection. The inversion mechanism in this embodiment further includes a reduction gear, which is connected between the drive member 62 and the rotating shaft 63 to reduce the rotational speed transmitted by the drive member 62 to the rotating shaft 63 and to improve the stability of the inversion of the positioning mechanism body 61.

[0117] Furthermore, conventional positioning mechanisms are typically attached to battery exchange equipment and move synchronously with the equipment, with the highest point of the positioning mechanism usually being the highest point of the battery exchange equipment. During the battery pack removal and installation process, the battery exchange equipment needs to be moved to the bottom of the electric vehicle, so the height of the electric vehicle's chassis affects the movement of the battery exchange equipment. In conventional technology, the height of the electric vehicle's chassis is usually less than the height of the battery exchange equipment, so during the battery pack removal and installation process, it is necessary to lift the electric vehicle before moving the battery exchange equipment to the bottom of the electric vehicle. Also, even after the battery pack removal and installation are complete, in order to prevent interference between the electric vehicle and the battery exchange equipment, it is necessary to move the battery exchange equipment from the bottom of the electric vehicle before lowering the electric vehicle, resulting in a long battery exchange time consumed throughout the entire process and low battery exchange efficiency.

[0118] Since the highest point of the positioning mechanism is usually also the highest point of the battery exchange equipment, the overall height of the battery exchange equipment is highest when the positioning mechanism is in a vertical position, and lowest when the positioning mechanism is in a horizontal position. Therefore, the reversible and foldable positioning mechanism provided in this embodiment can change the position of the highest point of the positioning mechanism, i.e., the overall height of the battery exchange equipment, by reversing and folding the positioning mechanism, thereby facilitating the battery exchange equipment to enter and exit the bottom of the electric vehicle. That is, the positioning mechanism can be kept in a horizontal position before the battery exchange equipment enters the bottom of the electric vehicle, at which point the overall height of the battery exchange equipment is lowest and can be below the height of the electric vehicle chassis, allowing the battery exchange equipment to enter the bottom of the electric vehicle without raising the electric vehicle. The process of raising the electric vehicle and the process of reversing the positioning mechanism to a vertical position can be performed simultaneously, and the process of lowering the electric vehicle and the process of folding the positioning mechanism to a horizontal position can also be performed simultaneously, thereby shortening the battery exchange time and increasing the battery exchange efficiency.

[0119] Specifically, the control method for the battery replacement equipment includes step 1, controlling the first positioning mechanism and the second positioning mechanism to invert to a horizontal position, and step 2, controlling the battery replacement equipment to move to the bottom of the electric vehicle.

[0120] The first and second positioning mechanisms may first be inverted to a horizontal position before the vehicle enters, and if the electric vehicle is not lifted, the battery exchange equipment can move directly to the bottom of the electric vehicle, shortening the battery exchange time and improving battery exchange efficiency without waiting for the electric vehicle to lift.

[0121] Herein, step three is further included, in which the first positioning mechanism and the second positioning mechanism are controlled to invert to a vertical position, thereby performing the corresponding battery removal process.

[0122] When the battery swapping equipment moves to the detachment position at the bottom of the electric vehicle, the first and second positioning mechanisms can be switched from a horizontal to a vertical position to achieve battery pack positioning. This process allows the electric vehicle to be raised synchronously, while simultaneously preventing the first and second positioning mechanisms from interfering with the bottom of the electric vehicle, and further shortening the battery swapping time and increasing battery swapping efficiency.

[0123] Here, before step one, it may further include determining the vehicle information of the electric vehicle and confirming whether it is necessary to reverse the position state of the first positioning mechanism or the second positioning mechanism based on relevant information such as the chassis height in the vehicle information. This allows for a determination of whether step one needs to be performed based on the chassis height of the electric vehicle, and for electric vehicles with a tall chassis, the battery replacement step can be simplified by not performing step one.

[0124] Next, to ensure uniform force distribution across the battery pack and enhance the stability of its positioning, a single battery exchange unit typically has multiple positioning mechanisms. In one preferred embodiment, each positioning mechanism can independently perform inversion and folding, and each positioning mechanism is flexibly controlled to avoid interference with one another. In other alternative embodiments, multiple positioning mechanisms in a single battery exchange unit can also be controlled collectively for inversion and folding.

[0125] Furthermore, in conventional technology, part of the positioning mechanism in a battery exchange device is provided on the frame of the battery exchange device, and another part is provided on the battery tray of the battery exchange device. To enable a single battery exchange device to position battery packs of different sizes, it is possible to achieve this simply by changing the battery tray where the positioning mechanism is located in a different position. This method is cumbersome and costly. On the other hand, when adopting the battery exchange device with the positioning mechanism of this embodiment, multiple sets of positioning mechanisms can all be attached to the frame of the battery exchange device. For battery packs of different sizes, it is only necessary to select that the corresponding positioning mechanism is in a vertical position and the other positioning mechanisms are folded in an inverted position. This eliminates the need to change the battery tray, resulting in lower costs. In another embodiment, the structure of the first and second positioning mechanisms can be a U-shaped structure different from this embodiment, such as an L-shaped or rod-shaped structure, as long as it can achieve positioning functionality with respect to the battery pack or electric vehicle chassis.

Those skilled in the art may make various changes or modifications to these embodiments without departing from the principles and essence of the present invention, and any such changes and modifications shall fall within the scope of protection of the present application.
