This improves the accuracy and efficiency of the installation process and reduces safety hazards during battery swapping.

Description

Technical Field

[0001] This invention relates to the field of battery swapping control, and in particular to a method, system, equipment, and medium for installing chassis-type batteries in battery swapping vehicles. Background Technology

[0002] Currently, electric vehicles are mainly powered by two methods: direct charging and fast battery swapping. Due to the limitations of charging time and location, many new energy electric vehicles are gradually adopting the fast battery swapping mode for energy replenishment.

[0003] For large vehicles, such as heavy trucks, the significant weight of the vehicle body and cargo necessitates a high capacity battery pack to support a range of hundreds of kilometers. Therefore, current technology for large new energy vehicles uses a top-mounted method to secure a large battery container to the vehicle's frame, with the container positioned close to the cab. This creates significant safety hazards for the driver and the vehicle during operation and battery swapping. Furthermore, battery malfunctions can directly cause personal injury to the driver. Additionally, the top-mounted method requires a large site for the battery swapping station, necessitating sufficient space for hoisting, transferring, and storing batteries, resulting in high construction costs.

[0004] Therefore, a safer, more reliable, and easier-to-adopt battery swapping mode is urgently needed for large vehicles. For example, a chassis-based battery swapping mode, similar to that used in passenger cars, could be adopted. However, in this mode, the swapping equipment (or swapping trolley) needs to travel under the vehicle to remove the existing battery pack from the chassis and then install the new one. Because of this, when replacing battery packs in heavy-duty trucks and other vehicles using chassis-based swapping, the large weight of both the vehicle and the battery can lead to low swapping efficiency when removing the old battery pack, posing safety hazards. Furthermore, the precise positioning of the swapping trolley is difficult to control for different vehicles, affecting battery pack removal and causing instability in the swapping system, or even leading to swapping failure. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art, such as poor driving control accuracy and efficiency of heavy trucks and other battery swapping vehicles during the battery swapping process, which cannot meet the actual battery swapping needs. The present invention provides a chassis-type battery installation method, system, equipment and medium for battery swapping vehicles.

[0006] The present invention solves the above-mentioned technical problems through the following technical solution:

[0007] A chassis-type battery installation method for a battery swapping vehicle, the vehicle having a beam arranged along its length, with multiple locking mechanisms mounted on the beam for battery pack replacement, each locking mechanism including a lock base with a lock groove and a lock tongue matching the lock groove, and multiple locking shafts at corresponding positions on the battery pack. The battery pack is removed or installed from the bottom of the vehicle via a battery swapping trolley. A first unlocking device is provided on the battery swapping platform of the trolley, and a second unlocking device matching the first unlocking device is built into the battery pack. An unlocking component is also mounted on the beam to move the lock tongue away from the lock groove. The chassis-type battery installation method includes:

[0008] Control the battery swapping trolley to move the battery pack to be installed to the battery swapping position at the bottom of the battery swapping vehicle;

[0009] The battery swapping platform is controlled to lift the battery pack, so that the first unlocking device pushes against the unlocking member through the second unlocking device, thereby moving the lock tongue away from the lock groove;

[0010] Control the battery swapping platform to perform the locking operation of the battery pack;

[0011] Unload the locking load force applied to the battery pack by the battery swapping platform.

[0012] In the above solution, during the installation of the battery pack, the first unlocking device is brought into contact with the second unlocking device. After the battery swapping platform is lifted into place, the second unlocking device on the battery pack is brought into contact with the unlocking block on the vehicle body, thereby moving the locking tongue away from the lock slot to meet the battery swapping requirements of the battery pack installation, ensuring the accuracy and efficiency of the installation process.

[0013] Preferably, the lock groove is an L-shaped lock groove, which includes a vertical section with a downward opening and a horizontal section connected to the closed end of the vertical section;

[0014] In the step of controlling the battery swapping platform to lift the battery pack, as the locking tongue is pushed away from the locking groove, the locking shaft simultaneously moves to the vertical section of the L-shaped locking groove in place.

[0015] The steps of controlling the battery swapping platform to perform the locking operation of the battery pack include:

[0016] Move the battery pack along the horizontal section of the L-shaped locking groove so that the locking shaft reaches the horizontal section's designated position;

[0017] The step of unloading the locking load force applied to the battery pack by the battery swapping platform includes:

[0018] The battery pack is controlled to descend to a preset height, causing the locking tongue to fall and lock the locking shaft in the L-shaped locking groove;

[0019] The battery pack is controlled to move a preset distance along the horizontal segment toward the vertical segment, so that the locking shaft moves to the locked position, thereby unloading the locking load force.

[0020] In the above scheme, during the installation of the battery pack, after the horizontal section is in place, the battery pack needs to be lowered to a preset height so that the locking tongue falls and locks the locking shaft of the battery pack. This is necessary to effectively perform the locking operation and avoid situations where the locking operation cannot be completed due to structural interference. After successful locking, the battery pack is moved horizontally a certain distance to release the locking load, completing the entire locking process. Timely pressure release can prevent pressure damage to the components and improve their lifespan.

[0021] Preferably, the battery swapping platform includes an upper plate and a lower plate arranged vertically. The lower plate is provided with a body positioning pin that mates with a body positioning hole at the bottom of the battery swapping vehicle, and the upper plate is provided with a battery positioning pin that mates with a battery positioning hole at the bottom of the battery pack.

[0022] The method further includes, prior to the step of controlling the battery swapping platform to lift the battery pack:

[0023] The battery swapping platform is positioned so that the vehicle body positioning pin is aligned with the vehicle body positioning hole.

[0024] In the above solution, the battery swapping platform can be positioned quickly and accurately through the vehicle positioning pins and positioning holes, thereby ensuring the timely execution of the subsequent battery swapping process.

[0025] Preferably, the preset height is less than the depth to which the battery positioning pin is inserted into the battery positioning hole.

[0026] Preferably, the first unlocking device and / or the second unlocking device have built-in elastic elements, which are in a compressed energy storage state after the battery swapping platform is lifted into place.

[0027] The preset height is greater than the energy storage distance of the elastic element.

[0028] In the above scheme, the setting of the preset height further ensures the effective execution of the locking operation and avoids the situation where the locking operation cannot be completed due to structural interference.

[0029] Preferably, the upper plate is provided with a floating tray for supporting the battery pack, and the first unlocking device is disposed on the upper plate with the top surface of the first unlocking device being higher than the bearing surface of the floating tray, so that when the floating tray supports the battery pack, the first unlocking device pushes against the second unlocking device and inserts into the battery pack;

[0030] The step of moving the battery pack along the horizontal segment of the L-shaped locking groove includes:

[0031] Drive the upper plate to move in a locking direction consistent with the horizontal segment;

[0032] The battery pack moves synchronously through the first unlocking device and the battery positioning pin.

[0033] The step of controlling the battery pack to move a preset distance along the horizontal segment toward the vertical segment includes:

[0034] Drive the upper plate to move in the unlocking direction, which is opposite to the locking direction;

[0035] The battery pack moves synchronously at least through the battery positioning pin.

[0036] In the above scheme, the top surface of the first unlocking device is higher than the bearing surface of the floating tray, which makes it easier to prevent the battery pack to be installed from being connected, making the subsequent docking more direct and convenient. At the same time, the battery pack is fixed by setting positioning pins so that the battery pack can be moved synchronously when the upper plate moves, which facilitates the precise positioning of the battery pack installation position, thereby ensuring the accuracy and efficiency of the installation process.

[0037] Preferably, the preset height is greater than the depth to which the first unlocking device is inserted into the battery pack.

[0038] In the above scheme, the setting of the preset height further ensures the effective execution of the locking operation and avoids the situation where the locking operation cannot be completed due to structural interference.

[0039] Preferably, the method further includes, before the step of controlling the battery swapping platform to lift the battery pack:

[0040] The battery pack is positioned so that the second unlocking device is aligned with the unlocking component.

[0041] In the above scheme, the positioning of the battery pack enables the second unlocking device to be aligned with the unlocking component quickly and accurately, thereby ensuring the timely execution of the subsequent battery swapping process.

[0042] Preferably, the chassis-type battery mounting method further includes:

[0043] The battery pack is carried on the battery swapping platform, so that the first unlocking device pushes against the second unlocking device and extends into the battery pack, and the second unlocking device extends out of the top surface of the battery pack; wherein, the top surface of the second unlocking device extending out of the battery pack is lower than the locking shaft.

[0044] In the above scheme, after the battery pack is placed on the battery swapping platform, the first unlocking device and the second unlocking device are connected by their own gravity. At the same time, the second unlocking device is pushed to extend out of the top surface of the battery pack. On the one hand, it can fix the battery pack to a certain extent, and on the other hand, extending out of the top surface of the battery pack further facilitates the alignment of the second unlocking device with the unlocking block in subsequent steps.

[0045] Preferably, the step of lifting the battery pack specifically includes:

[0046] The battery swapping platform is controlled to rise to a preset height at a first speed;

[0047] The battery swapping platform is controlled to rise at a second speed until the locking shaft reaches the vertical section's position, wherein the first speed is greater than the second speed.

[0048] In the above scheme, the battery swapping platform is controlled to rise rapidly before it reaches its position, and then rises slowly after it reaches its position. By adjusting the rising speed in the two control stages, the overall efficiency of the battery installation operation is ensured while maintaining control accuracy.

[0062] In the above scheme, during the installation of the battery pack, after the horizontal section is in place, the battery pack needs to be lowered to a preset height so that the locking tongue falls and locks the locking shaft of the battery pack. This is necessary to effectively perform the locking operation and avoid situations where the locking operation cannot be completed due to structural interference.

[0110] The present invention will be further illustrated by way of embodiments below, but the present invention is not limited to the scope of the embodiments described herein.

[0111] Example 1

[0112] The chassis-type battery installation method for battery swapping vehicles in this embodiment is applied to the chassis-type battery swapping structure of battery swapping vehicles. These vehicles include, but are not limited to, trucks, such as heavy-duty trucks. These vehicles have a large body weight and strong cargo-carrying capacity. The vehicle can be divided into two parts: a cab section and a cargo box section. The cargo box section is mostly a large, independent container that can be attached to the cab section. Additionally, the cab section has beams extending along the length of the vehicle body, i.e., a beam structure.

[0113] For example, such as Figure 1 As shown, the battery swapping vehicle 200 is the cab of a heavy-duty truck, with a large container or other cargo box that can be attached to it. Figure 1 (Not shown in the text), which enables heavy-duty trucks to have a high load-carrying capacity. For example... Figure 1 As shown, the battery swapping vehicle 200 has beams for locking the quick-swap battery pack 100, specifically two beams 201 extending along the length of the vehicle body. Locking mechanisms 202 are respectively installed on the two beams 201. Figure 1 (The battery pack is partially covered by the structure of the battery pack) and is connected to the battery pack 100 via a locking mechanism 202. In other words, the battery pack 100 is detachably connected from the bottom of the battery swapping vehicle 200 to the vehicle beam 201, realizing a bottom battery swapping mode, improving safety during vehicle operation, and making the battery replacement process safer and more reliable.

[0114] Based on the aforementioned quick-swap battery pack structure for heavy-duty trucks, due to the large size and weight of the batteries, installation of the battery pack necessitates moving it to the bottom of the battery swapping vehicle using specialized swapping equipment. For example... Figure 2 As shown, a battery swapping vehicle 500 is provided for swapping batteries. Figure 1 Battery packs are installed on heavy-duty trucks.

[0115] Based on the aforementioned structure of the battery swapping vehicle and battery swapping trolley, this embodiment provides a chassis-type battery installation method for a battery swapping vehicle suitable for the aforementioned battery swapping trolley, such as... Figure 3 As shown, the chassis-type battery mounting method includes:

[0116] Step 10: Control the battery swapping trolley to move the battery pack to be installed to the battery swapping position at the bottom of the battery swapping vehicle;

[0117] Specifically, according to Figure 1 The battery swapping vehicle 200 shown has a specific structure. When battery installation is required, the battery swapping vehicle 200 must first be parked in a designated battery swapping area to facilitate... Figure 2 The battery swapping cart 500 shown can move to the battery swapping location within the battery swapping area to perform battery installation operations.

[0118] For example Figure 2 and Figure 4 As shown, the battery swapping trolley 500 includes a base 510 and a walking mechanism 520. The walking mechanism 520 includes multiple walking wheels 521 disposed at the bottom of the base 510 and a drive unit disposed inside the base 510. The drive unit drives the walking wheels 521 to move the base 510, thereby realizing the overall movement of the battery swapping trolley 500.

[0119] The battery swapping trolley 500 also includes a battery swapping platform 530 located in the central area of ​​the base 510, and the battery swapping platform 530 is liftable and height-adjustable on the base 510. Thus, by controlling the battery swapping platform 530 to be in a lowered position, it is possible to ensure that the battery swapping trolley 500 can move smoothly into or out of the bottom of the battery swapping vehicle 200 at a lower height; and by controlling the battery swapping platform 530 to be in a raised position, it is possible to ensure sufficient height is available when the battery swapping platform 530 performs battery installation operations.

[0120] In addition, the battery swapping position mentioned here refers to the standard position that enables the battery swapping cart 500 to perform battery removal or installation operations on the battery swapping vehicle 200, that is, the necessary components for battery removal or installation on the battery swapping cart 500 are aligned with the necessary components for battery locking at the bottom of the battery swapping vehicle 200.

[0121] Step 20: Control the battery swapping platform to lift the battery pack, so that the first unlocking device pushes the unlocking component through the second unlocking device, thereby moving the lock tongue away from the lock slot;

[0122] Based on the specific structure of the battery swapping trolley 500 described above, the battery swapping platform 530 can be raised to the corresponding height position in this step. At this time, the battery swapping trolley 500 is entirely located at the bottom of the battery swapping vehicle 200. In this step, based on the above... Figure 1 The battery swapping vehicle 200 shown is, for example Figure 5 , Figure 6 and Figure 7 As shown, multiple locking mechanisms 202 are fixedly installed on the beam 201 of the battery swapping vehicle 200. The locking mechanisms 202 can be installed on any side wall or bottom wall of the beam 201. For example, the locking mechanisms 202 can be installed on the outer side walls of two beams 201 along the length of the vehicle body.

[0123] like Figure 6 and 7 As shown, the locking mechanism 202 includes a lock base 204 with a lock groove 203 and a lock tongue 205. Figure 8 and Figure 9 As shown, the battery pack 100 is provided with a locking shaft 101 that cooperates with the locking groove 203 and the locking tongue 205. The locking groove 203 is lower than the bottom wall of the vehicle beam 201, thereby creating open spaces on both sides of the locking groove 203 to facilitate movement of the locking shaft 101 on the battery pack 100 relative to the locking groove 203. When the battery pack 100 is locked on the vehicle beam 201 of the battery swapping vehicle 200, the locking shaft 101 of the battery pack 100 is locked in the locking groove 203 by the locking tongue 205.

[0124] For example Figure 4As shown, the battery swapping platform of the battery swapping vehicle is equipped with a first unlocking device 533. Correspondingly, an unlocking component 206 is also installed on the vehicle beam to drive the lock tongue away from the lock groove. See also Figure 10 The battery pack 100 has a built-in through hole 102 and a second unlocking device 103 located in the through hole that matches the first unlocking device 533. After the battery pack is lifted by the control platform, the first unlocking device 533 pushes against the unlocking member 206 through the second unlocking device 103, thereby moving the locking tongue 205 away from the locking groove 203.

[0125] Step 30: Control the battery swapping platform to perform a battery pack locking operation;

[0126] The battery swapping vehicle 500 also includes a drive mechanism 540 located at the bottom of the battery swapping platform 530. The drive mechanism 540 includes multiple drive motors that independently drive the vehicle body positioning part 531 and the battery positioning part 532. After the vehicle body positioning part 531 is positioned with the battery swapping vehicle 200, the corresponding drive motor drives the battery positioning part 532 to move along the length of the vehicle body 200, thereby driving the battery pack 100 to move synchronously. This causes the locking shaft 101 of the battery pack 100 to move within the locking groove 203, thereby locking the battery pack. Then, the battery pack is installed by the overall lifting and lowering movement of the battery swapping platform 530.

[0127] Step 40: Unload the locking load force applied to the battery pack by the battery swapping platform.

[0128] In the above solution, during the installation of the battery pack, the first unlocking device is brought into contact with the second unlocking device. After the battery swapping platform is lifted into place, the second unlocking device on the battery pack is brought into contact with the unlocking block on the vehicle body, thereby moving the locking tongue away from the lock slot to meet the battery swapping requirements of the battery pack installation, ensuring the accuracy and efficiency of the installation process.

[0129] Among them, the preferred implementation of the chassis-type battery installation method for battery swapping vehicles is as follows: Figure 11 As shown, the lock groove is an L-shaped lock groove, which includes a vertical section A with a downward opening and a horizontal section B that is connected to the closed end of the vertical section A.

[0130] In step 20, as the bolt is pushed away from the lock groove, the lock shaft moves simultaneously to the vertical section of the L-shaped lock groove in place.

[0131] Furthermore, such as Figure 12 As shown, step 30 specifically includes:

[0132] Step 301: Move the battery pack along the horizontal section of the L-shaped lock groove until the lock shaft reaches the horizontal section's designated position;

[0133] Step 40 specifically includes:

[0134] Step 401: Control the battery pack to descend to a preset height, causing the latch to drop and lock the lock shaft in the L-shaped lock groove;

[0135] Step 402: Control the battery pack to move a preset distance along the horizontal section toward the vertical section, so that the locking shaft moves to the locked position, thereby unloading the locking load force.

[0136] In the above scheme, during the installation of the battery pack, after the horizontal section is in place, the battery pack needs to be lowered to a preset height so that the locking tongue falls and locks the locking shaft of the battery pack. This is necessary to effectively perform the locking operation and avoid situations where the locking operation cannot be completed due to structural interference. After successful locking, the battery pack is moved horizontally a certain distance to release the locking load, completing the entire locking process. Timely pressure release can prevent pressure damage to the components and improve their lifespan.

[0137] In this embodiment, see Figure 4 and 5 The battery swapping platform includes an upper plate 540 and a lower plate 550 arranged vertically. The lower plate 550 is provided with a body positioning pin that mates with the body positioning hole at the bottom of the battery swapping vehicle. The upper plate 540 is provided with a battery positioning pin that mates with the battery positioning hole at the bottom of the battery pack. The preset height is less than the depth to which the battery positioning pin is inserted into the battery positioning hole.

[0138] Before step 20, see Figure 2 Chassis-mounted battery installation methods also include:

[0139] Step 11: Position the battery swapping platform so that the vehicle positioning pin is aligned with the vehicle positioning hole.

[0140] For details, see Figure 2 and 4 The battery swapping platform 530 includes a body positioning part 531, which is also provided with a body positioning pin that cooperates with the non-battery pack structure (such as the vehicle beam structure) of the battery swapping vehicle 200 for positioning, and is used to align with the body positioning holes on the vehicle.

[0141] In the above solution, the battery swapping platform can be positioned quickly and accurately through the vehicle positioning pins and positioning holes, thereby ensuring the timely execution of the subsequent battery swapping process.

[0142] In this embodiment, the first unlocking device and / or the second unlocking device have built-in elastic elements. After the battery swapping platform is lifted into place, the elastic elements are in a compressed energy storage state.

[0143] The preset height is greater than the energy storage distance of the elastic element.

[0144] In the above scheme, the setting of the preset height further ensures the effective execution of the locking operation and avoids the situation where the locking operation cannot be completed due to structural interference.

[0145] In this embodiment, as Figure 13 and 14 As shown, the upper plate 540 is provided with a floating tray 541 for carrying the battery pack. A first unlocking device 533 is disposed on the upper plate 540, and the top surface of the first unlocking device 533 is higher than the bearing surface of the floating tray 541, so that when the floating tray 541 carries the battery pack, the first unlocking device 533 pushes against the second unlocking device 103 and inserts into the battery pack; further, step 301 specifically includes:

[0146] Drive the upper plate to move in the locking direction consistent with the horizontal section;

[0147] The battery pack moves synchronously through the first unlocking device and the battery positioning pin.

[0148] Furthermore, step 402 specifically includes:

[0149] Drive the upper plate to move in the unlocking direction, which is opposite to the locking direction;

[0150] The battery pack moves synchronously at least through the battery positioning pins.

[0151] For details, see Figure 2 and 4 The battery swapping platform 530 includes a battery positioning part 532, which is also provided with a battery positioning pin that cooperates with the battery pack 100 for positioning. On the one hand, it is used to fix the battery pack, and on the other hand, it drives the battery pack to move synchronously through the battery positioning pin.

[0152] In the above scheme, the top surface of the first unlocking device is higher than the bearing surface of the floating tray, which makes it easier to prevent the battery pack to be installed from being connected, making the subsequent docking more direct and convenient. At the same time, the battery pack is fixed by setting positioning pins so that the battery pack can be moved synchronously when the upper plate moves, which facilitates the precise positioning of the battery pack installation position, thereby ensuring the accuracy and efficiency of the installation process.

[0153] In this embodiment, before step 20, see [link to previous section]. Figure 12 Chassis-mounted battery installation methods also include:

[0154] Step 12: Position the battery pack so that the second unlocking device is aligned with the unlocking component.

[0155] In the above scheme, the positioning of the battery pack enables the second unlocking device to be aligned with the unlocking component quickly and accurately, thereby ensuring the timely execution of the subsequent battery swapping process.

[0156] In this embodiment, the chassis-type battery mounting method further includes:

[0157] The battery pack is carried on the battery swapping platform, so that the first unlocking device pushes against the second unlocking device and extends into the battery pack, and the second unlocking device extends out of the top surface of the battery pack; wherein, the top surface of the second unlocking device extending out of the battery pack is lower than the locking shaft.

[0158] In the above scheme, after the battery pack is placed on the battery swapping platform, the first unlocking device and the second unlocking device are connected by their own gravity. At the same time, the second unlocking device is pushed to extend out of the top surface of the battery pack. On the one hand, it can fix the battery pack to a certain extent, and on the other hand, extending out of the top surface of the battery pack further facilitates the alignment of the second unlocking device with the unlocking block in subsequent steps.

[0159] In this embodiment, as Figure 15 As shown, step 20 specifically includes:

[0160] Step 2001: Control the battery swapping platform to rise to the preset height at the first speed;

[0161] Step 2002: Control the battery swapping platform to rise at a second speed until the locking shaft reaches the vertical section's position; wherein, the first speed is greater than the second speed.

[0162] In the above scheme, the battery swapping platform is controlled to rise rapidly before it reaches its position, and then rises slowly after it reaches its position. By adjusting the rising speed in the two control stages, the overall efficiency of the battery installation operation is ensured while maintaining control accuracy.

[0163] In this embodiment, during the installation of the battery pack, the first unlocking device and the second unlocking device are brought into contact. After the battery swapping platform is lifted into position, the second unlocking device on the battery pack is brought into contact with the unlocking block on the vehicle body, thereby moving the locking tongue away from the locking slot to meet the battery swapping requirements. This ensures the accuracy and efficiency of the installation process and reduces safety hazards during the battery swapping process.

[0164] Example 2

[0165] This embodiment provides a chassis-type battery mounting system for a battery swapping vehicle. The chassis-type battery swapping system is applied to the chassis-type battery swapping structure of the vehicle, which is the same as the structure in Embodiment 1, and will not be described again here. Figure 16 As shown, the chassis-type battery mounting system includes:

[0166] The mobile control module 1 is used to control the battery swapping trolley to move the battery pack to be installed to the battery swapping position at the bottom of the battery swapping vehicle;

[0167] By controlling the battery swapping platform 530 to be in a lowered position, it can be ensured that the battery swapping trolley 500 can move smoothly into or out of the battery swapping vehicle 200 at a lower height. Furthermore, by controlling the battery swapping platform 530 to be in a raised position, it can be ensured that there is sufficient height required when the battery swapping platform 530 performs battery installation operations.

[0168] In addition, the battery swapping position mentioned here refers to the standard position that enables the battery swapping cart 500 to perform battery removal or installation operations on the battery swapping vehicle 200, that is, the necessary components for battery removal or installation on the battery swapping cart 500 are aligned with the necessary components for battery locking at the bottom of the battery swapping vehicle 200.

[0169] Lifting module 2 is used to control the battery swapping platform to lift the battery pack, so that the first unlocking device pushes against the unlocking member through the second unlocking device, thereby driving the lock tongue away from the lock groove;

[0170] Based on the specific structure of the battery swapping trolley 500, the lifting module controls the battery swapping platform 530 to be lifted to the corresponding height position. At this time, the battery swapping trolley 500 is located at the bottom of the battery swapping vehicle 200.

[0171] See Figure 4 The battery swapping platform of the battery swapping vehicle is equipped with a first unlocking device 533. Correspondingly, an unlocking component for moving the lock tongue away from the lock groove is also installed on the vehicle beam. See also Figure 10 The battery pack 100 has a built-in through hole 102 and a second unlocking device 103 located in the through hole that matches the first unlocking device 533. After the battery pack is lifted by the control platform, the first unlocking device 533 pushes against the unlocking member through the second unlocking device 103, thereby moving the locking tongue 205 away from the locking groove 203.

[0172] Locking control module 3 is used to control the battery swapping platform to perform a locking operation on the battery pack;

[0173] In this process, after the vehicle body positioning unit 531 is positioned with the battery swapping vehicle 200, the corresponding drive motor drives the battery positioning unit 532 to move along the length of the vehicle body of the battery swapping vehicle 200, thereby driving the battery pack 100 to move synchronously. This causes the locking shaft 101 of the battery pack 100 to move within the locking groove 203, thereby locking the battery pack. Then, the battery pack is installed by lifting and moving the battery swapping platform 530 as a whole.

[0174] Force release module 4 is used to unload the locking load force applied by the battery swapping platform to the battery pack.

[0175] In the above solution, during the installation of the battery pack, the first unlocking device is brought into contact with the second unlocking device. After the battery swapping platform is lifted into place, the second unlocking device on the battery pack is brought into contact with the unlocking block on the vehicle body, thereby moving the locking tongue away from the lock slot to meet the battery swapping requirements of the battery pack installation, ensuring the accuracy and efficiency of the installation process.

[0176] Preferably, the lock groove is an L-shaped lock groove, which includes a vertical section with a downward opening and a horizontal section connected to the closed end of the vertical section;

[0177] During the process of the lifting module 2 controlling the battery swapping platform to lift the battery pack, as the locking tongue is pushed away from the locking groove, the locking shaft simultaneously moves to the vertical section of the L-shaped locking groove in place.

[0178] The locking control module 3 is specifically used for:

[0179] Move the battery pack along the horizontal section of the L-shaped locking groove so that the locking shaft reaches the horizontal section's designated position;

[0180] The force release module 4 specifically includes:

[0181] Vertical motion control unit 41 is used to control the battery pack to descend a preset height, so that the locking tongue falls to lock the locking shaft in the L-shaped locking groove;

[0182] The horizontal motion control unit 42 is used to control the battery pack to move a preset distance along the horizontal segment toward the vertical segment, so that the locking shaft moves to the locking position, thereby unloading the locking load force.

[0183] In the above scheme, during the installation of the battery pack, after the horizontal section is in place, the battery pack needs to be lowered to a preset height so that the locking tongue falls and locks the locking shaft of the battery pack. This is necessary to effectively perform the locking operation and avoid situations where the locking operation cannot be completed due to structural interference. After successful locking, the battery pack is moved horizontally a certain distance to release the locking load, completing the entire locking process. Timely pressure release can prevent pressure damage to the components and improve their lifespan.

[0184] In this embodiment, the battery swapping platform includes an upper plate and a lower plate arranged vertically. The lower plate is provided with a body positioning pin that mates with a body positioning hole at the bottom of the battery swapping vehicle, and the upper plate is provided with a battery positioning pin that mates with a battery positioning hole at the bottom of the battery pack. The preset height is less than the depth to which the battery positioning pin is inserted into the battery positioning hole.

[0185] The chassis-mounted battery system also includes:

[0186] The battery swapping platform positioning module 5 is used to position the battery swapping platform so that the vehicle positioning pin is aligned with the vehicle positioning hole.

[0187] For details, see Figure 2 and 4 The battery swapping platform 530 includes a body positioning part 531, which is also provided with a body positioning pin that cooperates with the non-battery pack structure (such as the vehicle beam structure) of the battery swapping vehicle 200 for positioning, and is used to align with the body positioning holes on the vehicle.

[0188] In the above solution, the battery swapping platform can be positioned quickly and accurately through the vehicle positioning pins and positioning holes, thereby ensuring the timely execution of the subsequent battery swapping process.

[0189] In this embodiment, the first unlocking device and / or the second unlocking device are equipped with elastic elements. After the battery swapping platform is lifted into place, the elastic elements are in a compressed energy storage state.

[0190] The preset height is greater than the energy storage distance of the elastic element.

[0191] In the above scheme, the setting of the preset height further ensures the effective execution of the locking operation and avoids the situation where the locking operation cannot be completed due to structural interference.

[0192] In this embodiment, the upper plate is provided with a floating tray for supporting the battery pack. The first unlocking device is disposed on the upper plate and the top surface of the first unlocking device is higher than the supporting surface of the floating tray, so that when the floating tray supports the battery pack, the first unlocking device pushes against the second unlocking device and inserts into the battery pack.

[0193] The locking control module 3 is specifically used to drive the upper plate to move in a locking direction consistent with the horizontal segment.

[0194] The battery pack moves synchronously through the first unlocking device and the battery positioning pin.

[0195] The horizontal motion control unit 42 is specifically used for:

[0196] Drive the upper plate to move in the unlocking direction, which is opposite to the locking direction;

[0197] The battery pack moves synchronously at least through the battery positioning pin.

[0198] For details, see Figure 2 and 4The battery swapping platform 530 includes a battery positioning part 532, which is also provided with a battery positioning pin that cooperates with the battery pack 100 for positioning. On the one hand, it is used to fix the battery pack, and on the other hand, it drives the battery pack to move synchronously through the battery positioning pin.

[0199] In the above scheme, the top surface of the first unlocking device is higher than the bearing surface of the floating tray, which makes it easier to prevent the battery pack to be installed from being connected, making the subsequent docking more direct and convenient. At the same time, the battery pack is fixed by setting positioning pins so that the battery pack can be moved synchronously when the upper plate moves, which facilitates the precise positioning of the battery pack installation position, thereby ensuring the accuracy and efficiency of the installation process.

[0200] The preset height is greater than the depth to which the first unlocking device is inserted into the battery pack.

[0201] In the above scheme, the setting of the preset height further ensures the effective execution of the locking operation and avoids the situation where the locking operation cannot be completed due to structural interference.

[0202] In this embodiment, the chassis-type battery mounting system further includes:

[0203] The battery pack positioning module 6 is used to position the battery pack so that the second unlocking device is aligned with the unlocking component.

[0204] Loading module 7 is used to carry the battery pack on the battery swapping platform, so that the first unlocking device pushes against the second unlocking device and extends into the battery pack, and the second unlocking device extends out of the top surface of the battery pack; wherein the top surface of the second unlocking device extending out of the battery pack is lower than the locking shaft.

[0205] In the above scheme, the positioning of the battery pack enables rapid and accurate alignment between the second unlocking device and the unlocking block, thereby ensuring the timely execution of the subsequent battery swapping process. Furthermore, after the battery pack is placed on the battery swapping platform, its own gravity allows the first and second unlocking devices to align. Simultaneously, pushing causes the second unlocking device to extend beyond the top surface of the battery pack. This provides some degree of fixation for the battery pack and further facilitates alignment between the second unlocking device and the unlocking block in subsequent steps.

[0206] In this embodiment, the lifting module 2 is specifically used for:

[0207] The battery swapping platform is controlled to rise to a preset height at a first speed;

[0208] The battery swapping platform is controlled to rise at a second speed until the locking shaft reaches the vertical section's position, wherein the first speed is greater than the second speed.

[0209] In the above scheme, the battery swapping platform is controlled to rise rapidly before it reaches its position, and then rises slowly after it reaches its position. By adjusting the rising speed in the two control stages, the overall efficiency of the battery installation operation is ensured while maintaining control accuracy.

[0210] In this embodiment, during the installation of the battery pack, the first unlocking device and the second unlocking device are brought into contact. After the battery swapping platform is lifted into position, the second unlocking device on the battery pack is brought into contact with the unlocking block on the vehicle body, thereby moving the locking tongue away from the locking slot to meet the battery swapping requirements. This ensures the accuracy and efficiency of the installation process and reduces safety hazards during the battery swapping process.
