Description

Technical Field

[0001] This invention relates to a quick-change bracket assembly and a battery swapping vehicle including the same. Background Technology

[0002] Existing battery swapping vehicles generally use two types of battery pack installation: fixed and quick-swap. Fixed batteries are typically mounted on the vehicle, with the vehicle itself serving as the charging point. Quick-swap battery packs, on the other hand, are usually mounted on a bracket on the vehicle using a removable installation method. A depleted battery pack can be removed and a fully charged one installed in the vehicle for individual replacement or charging. After the removed battery pack has been fully charged, it is then reinstalled on the vehicle.

[0003] For quick-swap battery packs, they are typically installed by connecting to an integrated quick-swap bracket on the battery swapping vehicle. However, integrated quick-swap brackets are large and heavy, making installation difficult; furthermore, the specifications of battery packs that can be accommodated by the same model of integrated quick-swap bracket are limited, making it difficult for integrated quick-swap brackets to adapt to various battery pack sizes. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the shortcomings of the existing technology where the installation of the integral quick-change bracket is difficult, and to provide a quick-change bracket assembly and a battery swapping vehicle including the same.

[0005] The present invention solves the above-mentioned technical problems through the following technical solution:

[0006] This invention provides a quick-swap bracket assembly for battery swapping vehicles, the quick-swap bracket assembly comprising:

[0007] Multiple first sub-supports, each of which is independently mounted on the body of the battery swapping vehicle;

[0008] A locking mechanism is provided for mounting the battery pack onto the quick-change bracket assembly. The locking mechanism includes multiple locking bases, each corresponding to one of the first sub-brackets.

[0009] In this solution, the aforementioned structural form is adopted. The battery pack is locked to multiple first sub-supports via a locking base. These first sub-supports are installed independently. Compared to an integrated quick-change bracket, each independent first sub-support is smaller and lighter, facilitating installation and improving assembly efficiency. Furthermore, the one-to-one correspondence between the locking base and the first sub-supports allows for the addition or reduction of the number of first sub-supports based on the specifications and quantity of the battery pack, offering high flexibility and improving the stability of battery pack installation.

[0010] Preferably, the vehicle body includes two beams extending along their length, and a plurality of first sub-supports are spaced apart along the length of the beams and mounted on the inner and / or outer sides of the beams.

[0015] In this solution, the above-mentioned structural form is adopted. Firstly, the second sub-support is spaced apart from the first sub-support to avoid contact interference between the second and first sub-supports. Secondly, multiple second sub-supports are installed independently, and each independent second sub-support is small and lightweight, making it easy to install and improving assembly efficiency. Thirdly, the second sub-supports are set one-to-one with the support bases, and the number of second sub-supports can be increased or decreased according to actual needs, thereby increasing or decreasing the support points of the battery pack and preventing the battery pack from falling off during the battery swapping vehicle's operation.

[0016] Preferably, the vehicle body includes two beams extending along their length direction, and a plurality of first sub-supports and a plurality of second sub-supports are respectively spaced apart along the length direction of the beams and installed on the inner and / or outer sides of the beams.

[0017] Along the length of the vehicle beam, a plurality of second sub-supports are disposed on both sides of a plurality of first sub-supports.

[0018] In this solution, the above-mentioned structural form is adopted, and multiple second sub-supports are arranged along the length of the vehicle beam. This makes better use of the length of the vehicle beam to set up support seats, which is beneficial to the load-bearing stability of the battery pack.

[0019] Preferably, the lock base is integrally formed with the corresponding first sub-bracket.

[0020] In this solution, the above-mentioned structural form is adopted, which eliminates the installation error between the lock base and the first sub-bracket, improves the installation accuracy of the locking mechanism, and further improves the locking accuracy of the battery pack.

[0021] Preferably, the support base and the corresponding second sub-support are integrally formed.

[0022] In this solution, the above-mentioned structural form is adopted, which eliminates the installation error between the support base and the second sub-support and improves the installation accuracy of the support base.

[0023] Preferably, the first sub-bracket and / or the second sub-bracket include a mounting portion and a connecting portion, at least one end of the connecting portion is connected to the mounting portion, and the mounting portion extends from the end of the connecting portion toward the vehicle body and is connected to the vehicle body.

[0024] In this solution, the above-mentioned structural form is adopted, and the first sub-support is formed by interconnected mounting parts and connecting parts, thereby increasing the strength of the first sub-support.

[0025] Preferably, the two ends of the connecting part are respectively connected to the mounting part, the two mounting parts are spaced apart along the height direction of the vehicle body, and the lock base is connected to the lower surface of the mounting part located below.

[0026] In this solution, the above-mentioned structural form is adopted, and both ends of the connecting part are connected to the vehicle body through the mounting part, thereby enhancing the connection strength between the first sub-support and the vehicle body.

[0027] Preferably, the mounting part includes a connecting plate and a mounting plate, with the two ends of the connecting plate respectively connected to the connecting part and the mounting plate, and the mounting plate being detachably connected to the vehicle body;

[0028] The mounting plate extends along the length of the vehicle body, and the connecting plate extends along the width of the vehicle body.

[0029] In this solution, the above-mentioned structural form is adopted, and the mounting plate extending along the length direction of the vehicle body and the connecting plate extending along the width direction of the vehicle body constitute the mounting part. The spatial layout is reasonable and avoids contact interference between the mounting plate and the connecting plate.

[0030] Preferably, the locking mechanism includes a locking link and a plurality of locking tongues corresponding to the lock base. The locking link is rotatably connected to the lock base through the locking tongues, and the locking link is located between the two mounting portions.

[0031] In this solution, the above-mentioned structure is adopted. During the process of the battery pack entering the battery pack receiving area composed of the quick-change bracket assembly, the locking linkage is triggered to drive the locking tongue to rotate in the lock base, thereby locking the locking shaft of the battery pack in the lock base, which is convenient.

[0032] Preferably, the lock base has a lock groove and a first opening communicating with the lock groove; the first end of the lock tongue is rotatably connected to the lock base, and the second end of the lock tongue is rotatably connected to the lock linkage; the lock linkage drives the lock tongue to rotate and open the first opening under the action of an external mechanism.

[0033] In this solution, the above-mentioned structure is adopted. During the rotation of the locking tongue, the locking shaft of the battery pack enters the locking groove from the first opening.

[0034] Preferably, the top of the lock base is provided with a lock tongue groove for installing the lock tongue, and the lock tongue groove is connected to the lock groove. The mounting part located below is provided with a through hole corresponding to the lock tongue groove. The second end of the lock tongue passes through the lock tongue groove and the through hole in sequence and is rotatably connected to the lock linkage.

[0035] In this solution, the above-mentioned structural form is adopted. By opening a lock tongue groove on the lock base and opening a through hole on the mounting part, installation space is reserved for the lock tongue. The spatial layout is reasonable and the structure is compact.

[0036] Preferably, a reinforcing rib is provided between the two mounting parts.

[0037] In this solution, the above-mentioned structural form is adopted to improve the structural strength of the first sub-support and reduce or avoid the twisting, breakage, and other situations that may occur in the quick-change support assembly during its use.

[0080] The present invention will be described more clearly and completely below by way of embodiments and in conjunction with the accompanying drawings, but the present invention is not limited to the scope of the following embodiments.

[0081] This invention provides a battery swapping vehicle, which includes a quick-swap bracket assembly, and the battery pack is fixed to the battery swapping vehicle through the quick-swap bracket assembly.

[0082] like Figures 1 to 6As shown, the quick-swap bracket assembly includes multiple first sub-brackets 1, a locking mechanism 2, a support base 3, multiple second sub-brackets 4, and an electrical connector mounting plate 5. The first sub-brackets 1 are independently mounted on the body 6 of the battery swapping vehicle. The locking mechanism 2 is connected to the first sub-brackets 1 and is used for mounting the battery pack onto the quick-swap bracket assembly. The locking mechanism 2 includes multiple locking bases 21, each corresponding to a first sub-bracket 1. The battery pack is locked to the multiple first sub-brackets 1 via the locking bases 21. The multiple first sub-brackets 1 used for locking the battery pack are installed independently. Compared to the integrated quick-swap bracket, each independent first sub-bracket 1 is smaller and lighter, facilitating installation and improving assembly efficiency. Furthermore, the one-to-one correspondence between the locking bases 21 and the first sub-brackets 1 allows for the addition or reduction of the number of first sub-brackets 1 according to the specifications and quantity of the battery pack, providing high flexibility and improving the stability of battery pack installation.

[0083] like Figure 1 and Figure 2 As shown, the vehicle body 6 includes two beams 61 extending along their length direction, and a plurality of first sub-supports 1 are spaced apart along the length direction of the beams 61 and installed on the inner side of the beams 61. The arrangement of the plurality of first sub-supports 1 along the length direction of the beams 61 makes better use of the length direction of the beams 61 to set up the locking mechanism 2, which is beneficial to the load-bearing stability of the battery pack.

[0084] In other embodiments, a plurality of first sub-supports 1 are spaced apart along the length of the vehicle beam 61 and installed on the outer side of the vehicle beam 61. Alternatively, a plurality of first sub-supports 1 spaced apart along the length of the vehicle beam 61 are installed on both the inner and outer sides of the vehicle beam 61, and first sub-supports 1 are installed on both the inner and outer sides of the vehicle beam 61, that is, locking mechanisms 2 are installed on both the inner and outer sides of the vehicle beam 61, further improving the stability of the battery pack installation.

[0085] The inner and outer sides of the beam 61 are reserved with assembly space for the first sub-bracket 1, which can be reasonably set according to the shape of the battery pack, and the installation position of the first sub-bracket 1 is highly flexible.

[0086] The lock base 21 is integrally formed with the corresponding first sub-bracket 1, which eliminates the installation error between the lock base 21 and the first sub-bracket 1, improves the installation accuracy of the locking mechanism 2, and further improves the locking accuracy of the battery pack.

[0087] like Figure 4 As shown, the first sub-bracket 1 includes a mounting portion 11 and a connecting portion 12. At least one end of the connecting portion 12 is connected to the mounting portion 11. The mounting portion 11 extends from the end of the connecting portion 12 toward the vehicle body 6 and is connected to the vehicle body 6. The first sub-bracket 1 is formed by the interconnected mounting portion 11 and the connecting portion 12, thereby increasing the strength of the first sub-bracket 1.

[0088] In this embodiment, the two ends of the connecting part 12 are respectively connected to the mounting parts 11, and the two mounting parts 11 are spaced apart along the height direction of the vehicle body 6. The lock base 21 is connected to the lower surface of the mounting part 11 located below. Both ends of the connecting part 12 are connected to the vehicle body 6 through the mounting parts 11, thereby enhancing the connection strength between the first sub-bracket 1 and the vehicle body 6.

[0089] In this embodiment, the mounting part 11 includes a connecting plate 111 and a mounting plate 112. The two ends of the connecting plate 111 are respectively connected to the connecting part 12 and the mounting plate 112. The mounting plate 112 is detachably connected to the vehicle body 6. The mounting plate 112 extends along the length direction of the vehicle body 6, and the connecting plate 111 extends along the width direction of the vehicle body 6. The mounting plate 112 extending along the length direction of the vehicle body 6 and the connecting plate extending along the width direction of the vehicle body 6 constitute the mounting part 11. The spatial layout is reasonable, avoiding contact interference between the mounting plate 112 and the connecting plate 111.

[0090] like Figure 4 As shown, the connecting part 12 is a plate-shaped component. Both the upper and lower ends of the connecting part 12 are connected to the connecting plate 111 and the mounting plate 112. The connecting part 12 and the connecting plate 111 are set at a preset angle, and the connecting plate 111 and the mounting plate 112 are also set at a preset angle. The mounting plate 112 has mounting holes along the length and / or width direction of the vehicle beam 61. Bolts pass through the mounting holes to fix the mounting plate 112 to the vehicle beam 61. Of course, in addition to bolts, rivets, welding studs, or other connecting components can also be used; alternatively, the mounting plate 112 can be directly welded to the vehicle beam 61.

[0091] More specifically, the connecting part 12 and the connecting plate 111 are set at 90 degrees, and the connecting plate 111 and the mounting plate 112 are set at 90 degrees, which results in a reasonable spatial layout and a compact structure.

[0092] like Figure 3 and Figure 4 As shown, the locking mechanism 2 includes a locking link 22 and multiple locking tongues 23 corresponding to the lock base 21. The locking link 22 is rotatably connected to the lock base 21 via the locking tongues 23, and the locking link 22 is located between the two mounting parts 11. During the process of the battery pack entering the battery pack receiving area composed of the quick-change bracket assembly, the locking link 22 is triggered to drive the locking tongues 23 to rotate within the lock base 21, thereby locking the battery pack's locking shaft within the lock base 21, making locking convenient.

[0093] In this embodiment, the lock base 21 has a lock groove 211 and a first opening 212 communicating with the lock groove 211; the first end of the lock tongue 23 is rotatably connected to the lock base 21, and the second end of the lock tongue 23 is rotatably connected to the lock link 22; the lock link 22 drives the lock tongue 23 to rotate and open the first opening 212 under the action of an external mechanism. During the rotation of the lock tongue 23, the locking shaft of the battery pack enters the lock groove 211 from the first opening 212, and the lock tongue 23 rotates to seal the first opening 212 under the gravity of the lock link 22, thereby locking the battery pack in the locking mechanism 2. The locking mechanism 2 connects the vehicle beam 61 and the battery pack, and the connection between the vehicle beam 61 and the battery pack is highly stable and secure.

[0094] In this embodiment, the top of the lock base 21 is provided with a lock tongue groove for mounting the lock tongue 23, and the lock tongue groove is connected to the lock groove 211. The mounting part 11 located below is provided with a through hole 113 corresponding to the lock tongue groove. The second end of the lock tongue 23 passes through the lock tongue groove and the through hole 113 in sequence and is rotatably connected to the lock connecting rod 22. By providing a lock tongue groove on the lock base 21 and a through hole on the mounting part 11, mounting space is reserved for the lock tongue 23, resulting in a reasonable spatial layout and a compact structure.

[0095] Specifically, the inverted L-shaped slot formed by the interconnected lock groove 211 and the first opening 212 is recessed upward from the bottom surface of the lock base 21 and is used to allow the lock shaft installed in the battery pack to enter. The lock base 21 is provided with a lock tongue groove for installing the lock tongue 23. The lock tongue groove is recessed downward from the top surface of the lock base 21 and is connected to the lock groove 211. One end of the lock tongue 23 passes through the lock tongue groove and is axially connected to the lock linkage 22. The lock linkage 22 is located above each lock base 21. The lock tongue 23 is axially connected to the lock base 21, so that the lifting and lowering of the lock linkage 22 can drive the lock tongue 23 to rotate around the shaft connection point in the lock base 21, thereby realizing the lock tongue 23 entering or leaving the lock groove 211, and thus realizing the switching between the two states of the battery pack lock shaft being engaged in the lock groove 211 and leaving the lock groove 211.

[0096] The locking mechanism 2 also includes an elastic reset component 24. The elastic reset component 24 applies force to the locking link 22 and drives the latches 23 back into the lock groove 211. The elastic reset component 24 applies force to the locking link 22 and exerts a downward force on the locking link 22. The locking link 22 will drive the multiple latches 23 to rotate downward and extend into the lock groove 211, so that the multiple latches 23 are in the locked position, further improving the stability of the locking mechanism 2 in the locked state. In this embodiment, the elastic reset component 24 is a spring.

[0097] like Figure 4 As shown, a reinforcing rib 13 is connected between the two mounting parts 11 to improve the structural strength of the first sub-support 1 and reduce or avoid the twisting, breakage, etc. of the quick-change support assembly during its use.

[0098] In this embodiment, the reinforcing rib 13 is provided with a clearance hole 131, and the locking rod 22 passes through the clearance hole 131. The layout is reasonable and avoids contact interference between the locking rod 22 and the first sub-support 1.

[0099] like Figure 1 , Figure 2 and Figure 6 As shown, the quick-swap bracket assembly also includes multiple support seats 3, which provide multiple support points for supporting the battery pack. The support seats 3 increase the connection points between the battery pack and the quick-swap bracket assembly, reducing the load on the first sub-bracket 1 and the locking mechanism 2 when carrying the battery pack, thus improving the service life of the first sub-bracket 1 and the locking mechanism 2, and also making the battery pack more stably connected to the battery swapping vehicle.

[0100] In this embodiment, the quick-swap bracket assembly includes multiple second sub-brackets 4. The second sub-brackets 4 are spaced apart from the first sub-brackets 1 and independently installed on the body 6 of the battery swapping vehicle. Each second sub-bracket 4 corresponds to a support base 3. Firstly, the spaced-apart arrangement of the second sub-brackets 4 and the first sub-brackets 1 avoids contact interference between them. Secondly, the multiple second sub-brackets 4 are installed independently, and each independent second sub-bracket 4 is small and lightweight, facilitating installation and improving assembly efficiency. Thirdly, the one-to-one correspondence between the second sub-brackets 4 and the support base 3 allows for adjustments to the number of second sub-brackets 4 and the number of support points for the battery pack, preventing the battery pack from falling off during vehicle operation.

[0101] The vehicle body 6 includes two beams 61 extending along their length. Multiple first sub-supports 1 and multiple second sub-supports 4 are spaced apart along the length of the beams 61 and installed on the inner side of the beams 61. The multiple second sub-supports 4 are arranged along the length of the beams 61, making better use of the support seats 3 along the length of the beams 61, which is beneficial to the load-bearing stability of the battery pack. Along the length of the beams 61, the multiple second sub-supports 4 are located on both sides of the multiple first sub-supports 1. In other words, support points for the battery pack are provided on both sides of the locking point between the battery pack and the quick-change bracket assembly, resulting in a reasonable spatial layout and good stability.

[0102] In other embodiments, a plurality of first sub-supports 1 and a plurality of second sub-supports 4 are respectively spaced apart along the length direction of the vehicle beam 61 and installed on the outer side of the vehicle beam 61. Alternatively, a plurality of second sub-supports 4 spaced apart along the length direction of the vehicle beam 61 are installed on both the inner and outer sides of the vehicle beam 61, and second sub-supports 4 are installed on both the inner and outer sides of the vehicle beam 61, that is, support seats 3 are installed on both the inner and outer sides of the vehicle beam 61, further improving the stability of the battery pack installation.

[0103] Specifically, such as Figure 1 and Figure 2 As shown, along the length of the beam 61, three first sub-supports 1 are installed at intervals on the inner side of the two beams 61 respectively. Three second sub-supports 4 are installed at intervals on one side of the three first sub-supports 1, and two second sub-supports 4 are installed at intervals on the other side.

[0104] The support base 3 and the corresponding second sub-support 4 are integrally formed, which eliminates the installation error between the support base 3 and the second sub-support 4 and improves the installation accuracy of the support base 3.

[0105] like Figure 5 As shown, the second sub-support 4 has a similar structure to the first sub-support 1. Both the second sub-support 4 and the first sub-support 1 can be processed using the same production line, resulting in high production efficiency and low processing costs. Furthermore, if the second sub-support 4 is damaged, the first sub-support 1 can be used as a replacement, demonstrating high parts replaceability. Specifically, the second sub-support 4 includes a mounting portion 11 and a connecting portion 12. At least one end of the connecting portion 12 is connected to the mounting portion 11. The mounting portion 11 extends from the end of the connecting portion 12 towards the vehicle body 6 and connects to the vehicle body 6. The two ends of the connecting portion 12 are respectively connected to the mounting portions 11, and the two mounting portions 11 are spaced apart along the height direction of the vehicle body 6. The locking base 21 is connected to the lower surface of the lower mounting portion 11. The mounting portion 11 includes a connecting plate 111 and a mounting plate 112. The two ends of the connecting plate 111 are respectively connected to the connecting portion 12 and the mounting plate 112. The mounting plate 112 is detachably connected to the vehicle body 6, extending along the length direction of the vehicle body 6, while the connecting plate 111 extends along the width direction of the vehicle body 6. However, the mounting portion 11 located below does not require a through hole 113; it serves only as a connection point between the support base 3 and the beam 61. In other embodiments, other similar brackets capable of achieving the connection function can be applied.

[0106] like Figure 6 As shown, the support base 3 has a support groove 31 and a second opening 32 communicating with the support groove 31. During the process of the battery pack entering the locking mechanism 2, the support shaft on the battery pack can simultaneously enter the support groove 31 through the second opening 32, which helps to improve the rationality of the spatial layout.

[0107] In this embodiment, the support base 3 has a similar structure to the lock base 21, but it does not have a locking function and only serves as a support platform for the battery pack. In other embodiments, other similar support bases with support platforms can be applied.

[0108] The lower surface of the support base 3 and the lower surface of the lock base 21 are located on the same plane, which improves the installation accuracy of the quick-change bracket assembly.

[0109] Preferably, the lower surface of the support groove 31 (the surface closest to the ground when in use) and the lower surface of the lock groove 211 (the surface closest to the ground when in use) are located on the same plane, which can make the battery pack placed stably.

[0110] like Figure 6 As shown, an electrical connector mounting plate 5 is provided on the vehicle beam 61. An electrical connector mounting seat 53 is mounted on the electrical connector mounting plate 5 to facilitate the docking of the electrical connector with the electrical connection components on the battery pack. The electrical connector mounting plate 5 includes a mounting block 51 and a connecting block 52. The mounting block 51 is used to mount the electrical connector mounting seat 53. The mounting block 51 faces the battery pack and at least one end is connected to the connecting block 52. The connecting block 52 extends from the end of the mounting block 51 towards the vehicle beam 61 and connects to the vehicle beam. The interconnected mounting block 51 and connecting block 52 form the electrical connector mounting plate 5, increasing the strength of the electrical connector mounting plate 5. In addition, the mounting block 51 faces the battery pack, facilitating the docking of the battery pack with the electrical connector.

[0111] Specifically, both the mounting block 51 and the connecting block 52 adopt a plate-like structure. The upper and lower ends of the mounting block 51 are connected to the connecting block 52. The connecting block 52 is composed of a first connecting plate and a second connecting plate that are connected to each other. The two ends of the first connecting plate are respectively connected to the second connecting plate and the mounting block 51. The first connecting plate and the second connecting plate are set at 90 degrees, and the second connecting plate is in close contact with the vehicle beam 61.

[0112] In practical use, the battery pack enters the vehicle 61 from the bottom upwards. The unlocking mechanism of the battery swapping device pushes the locking rod 22 upwards, causing the locking tongue 23 to open the first opening 212. The battery's locking shaft is inserted into the locking groove 211 from the bottom surface of the corresponding lock base 21. The unlocking mechanism of the battery swapping device no longer acts on the locking rod 22. The locking tongue 23 rotates under the gravity of the locking rod 22, thus blocking the return path of the locking shaft, thereby resetting the locking tongue 23 and completing the battery pack suspension process. At this time, the battery pack is completely locked to the battery swapping vehicle. During the process of the battery pack's locking shaft entering the locking groove 211, the battery pack's support shaft simultaneously enters the support groove 31 through the second opening 32. When the battery needs to be replaced, the unlocking mechanism pushes the locking rod 22 up, thereby rotating the locking tongue 23 and opening the first opening 212. At this time, the battery pack is moved to make the locking shaft exit from the locking groove 211 and the support shaft exit from the support groove 31. Then, the battery pack is driven to move downward, the locking shaft exits from the first opening 212 and the support shaft exits from the second opening 32, thus completing the battery pack removal process.

[0113] While specific embodiments of the present invention have been described above, those skilled in the art should understand that these are merely illustrative examples, and the scope of protection of the present invention is defined by the appended claims. Those skilled in the art can make various changes or modifications to these embodiments without departing from the principles and essence of the present invention, but all such changes and modifications fall within the scope of protection of the present invention.
