Description

Technical Field

[0001] This utility model belongs to the field of new energy vehicle technology, specifically relating to a temperature control structure, battery compartment, and battery swapping new energy vehicle. Background Technology

[0002] The battery pack in a new energy vehicle is its energy storage component. During charging and discharging, the battery pack's operating temperature rises. Excessively high operating temperatures reduce its lifespan and efficiency, and also pose a safety hazard of thermal runaway. Therefore, ensuring that the vehicle battery and other heat-generating power systems operate within their normal temperature range is crucial. Consequently, the development of a new energy vehicle battery thermal management system is essential and vital for ensuring and managing the battery pack's operation within its normal temperature range.

[0003] In traditional battery pack temperature control solutions, each battery pack contains an integrated water-cooled plate and other heat exchange structures to control its temperature. This approach, with each battery pack having its own heat exchange plate, increases both the cost and the difficulty of assembly and disassembly due to the need to insert and remove the heat exchange plate. This also increases the risk of damage to the heat exchange plate. Furthermore, because the heat exchange plate is an integral part of the battery pack, it cannot be repaired individually, or the repair costs are prohibitively high. Utility Model Content

[0004] The purpose of this utility model is to provide a temperature control structure for new energy vehicles to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides a temperature control structure for a new energy vehicle, including a housing space, a heat exchange plate, and a drive mechanism. At least one battery pack is disposed within the housing space, and the battery pack can be pulled out of the housing space through a side opening of the vehicle. The heat exchange plate extends at least partially into the battery pack housing space of the vehicle, and has two positional states: a pressed state where the heat exchange plate is in contact with the surface of the battery pack when the battery pack is normally installed, and a separated state where the heat exchange plate is detached from the surface of the battery pack when the battery pack is ready to be disassembled. The drive mechanism is configured to switch the heat exchange plate between the pressed state and the separated state. This separate design between the battery pack and the heat exchange plate structure facilitates individual disassembly and replacement of the heat exchange plate, reduces maintenance costs, eliminates the need for connecting heat exchange plate pipes during battery pack assembly and disassembly, reduces the difficulty of battery pack disassembly, extends the service life of the heat exchange structure, reduces the probability of failure and damage, and actively separates the heat exchange plate when the battery pack needs to be disassembled, further reducing the difficulty of battery pack disassembly, assembly, or insertion / removal.

[0006] In one embodiment of this invention, the heat exchange plate is rotatably mounted, and the drive mechanism can push the heat exchange plate to deflect and press it against the battery pack. By setting the movement mode of the deflectable heat exchange plate, the movement amplitude is smaller, the separation and pressing operations are changed more quickly, the structural design is more convenient, and the drive adjustment of the heat exchange plate is easier.

[0007] In one embodiment of this utility model, the driving mechanism includes a guide surface on the inner wall of the battery compartment cover, with the end of the heat exchange plate extending to the cover and contacting the guide surface. During the opening or closing of the cover, the end of the heat exchange plate slides along the guide surface. This driving method has an extremely simple structure; by naturally opening the cover, the positional state between the heat exchange plate and the battery pack can be changed, reducing design and matching costs and enhancing practicality.

[0008] In one embodiment of this invention, the heat exchange plate is configured to be lifted and movable. A drive mechanism drives the heat exchange plate to move up and down, thereby pressing or separating it from the battery pack surface. This design results in more uniform pressure between the heat exchange plate and the battery pack surface, leading to more uniform heat exchange and ensuring higher heat exchange efficiency.

[0009] In one embodiment of this utility model, the driving mechanism is a wedge mechanism, including a horizontally slidable slider and wedges fixedly mounted on the opposing surfaces of the slider and the heat exchange plate, respectively. The inclined surfaces of the two wedges abut against each other and slide in cooperation. Optimizing the structure of the heat exchange plate driving mechanism ensures more uniform pressure on the battery pack from the heat exchange plate, thereby avoiding deformation caused by long-term use, resulting in a longer service life and a lower failure rate.

[0010] In one embodiment of this invention, a rebound device is arranged at the end of the slider away from the opening of the accommodating space for pushing the slider to reset. After the accommodating space cover is opened, the rebound device pushes the slider to reset. When replacing the battery pack, it is not necessary to actively pull the slider to reset using the hook, thus speeding up the battery pack replacement efficiency.

[0011] In one embodiment of this utility model, the rebound device is set as a press-type self-locking rebound device to ensure that when performing other related battery pack or storage space maintenance operations, the slider will not pop out immediately after the compartment cover is opened, so as to avoid affecting the maintenance work of the operator.

[0012] Furthermore, this utility model also relates to a battery compartment, including at least one battery pack slot, each battery pack slot having the temperature control structure described above. Designed for the heat exchange requirements of multiple battery packs in this battery compartment, each slot is equipped with a corresponding heat exchange plate. During the opening and closing of the battery compartment cover, multiple guide surfaces corresponding to these surfaces on the inner wall of the cover engage with the ends of each heat exchange plate, causing the heat exchange plates in each slot to deflect and press against the internal battery packs. This facilitates convenient and quick disassembly and replacement of any one or more battery packs within the battery compartment.

[0013] This utility model also relates to a battery-swapping new energy vehicle, including a vehicle body with a battery compartment as described above installed on the vehicle body. For battery-swapping vehicles, the core of battery swapping is the removal of the old battery pack and the insertion of a new battery pack within the battery compartment. This requires repeated separation and compression operations between the heat exchange plate and the battery pack. By matching the aforementioned temperature control structure to the battery compartment on the vehicle body, rapid battery pack replacement in battery-swapping new energy vehicles can be achieved, greatly improving the user's battery swapping experience while ensuring the temperature control effect of the battery pack and improving its charging and discharging efficiency.

[0014] In summary, the technical effects and advantages of this utility model are as follows: the temperature control structure, such as the heat exchange plate, is designed relatively independently from the battery pack. On the one hand, when the heat exchange plate is damaged, it can be replaced separately. Compared with the traditional integrated structure of the heat exchange plate and battery pack, there is no need to disassemble and repair the entire battery pack, greatly reducing maintenance costs. On the other hand, it avoids repeatedly plugging and unplugging the pipe joints of the heat exchange plate when disassembling and assembling the battery pack, reducing the difficulty of battery pack disassembly and assembly and the probability of damage to the heat exchange plate pipes. It is especially suitable for automated battery pack disassembly and assembly equipment. Actively control the pressing and separation states between the heat exchange plate and the battery pack. When the battery pack needs to be disassembled, the heat exchange plate is separated. While ensuring the heat exchange efficiency of the battery pack, the disassembly difficulty of the battery pack is reduced, the service life of the heat exchange structure is increased, the probability of failure and damage is reduced, and maintenance costs are reduced simultaneously. Furthermore, various improved heat exchanger drive methods have been optimized to make the structure simple, the configuration cost low, the design and manufacturing difficulty low, and the stability high, the service life long, and the practicality strong.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] This utility model provides, for example Figure 1 The temperature control structure of a new energy vehicle shown includes a housing space 3, a heat exchange plate 1, and a drive mechanism 2. The heat exchange plate 1 extends at least partially into the housing space 3 of the vehicle's battery pack 4 and is configured to move closer to or further away from the battery pack 4. The heat exchange plate can be a water-cooled plate, a semiconductor cooling chip, or other components with heat exchange functions. The heat exchange plate 1 can be completely installed inside the housing space 3 of the battery pack 4, or it can be connected to the vehicle body and partially extend into the housing space 3 of the battery pack 4. Furthermore, the heat exchange plate 1 has various ways of moving closer to and further away from the battery pack 4, such as directly lifting and lowering within the housing space 3 of the battery pack 4, or pressing against the battery pack 4 by deflection as disclosed in this embodiment. The drive mechanism 2 is capable of driving the heat exchange plate 1 to change its set position. When the battery pack is located within the accommodating space, the drive mechanism 2 drives the heat exchange plate 1 to press against the surface of the battery pack 4, exchanging heat with the battery pack 4. When it is necessary to remove the battery pack 4 from the accommodating space, the heat exchange plate 1 separates from the surface of the battery pack 4, and the friction between the battery pack 4 and the heat exchange plate 1 is lost. At this time, the battery pack 4 can be removed or inserted more easily. The drive mechanism can be implemented by means of, but not limited to, pushing with an electric push rod, or driving with a motor cam to drive with a motor and transmission structure. It can actively control the pressing and separating states of the heat exchange plate 1 and the battery pack 4, ensuring that the temperature control effect of the heat exchange plate 1 is not affected, while the removal and installation of the battery pack 4 is not obstructed by the heat exchange plate 1.

[0019] In addition, the temperature control structure, such as the heat exchange plate 1, is relatively independent from the battery pack 4. On the one hand, when the heat exchange plate is damaged, the heat exchange plate 1 can be directly replaced. Compared with the traditional integrated structure of the heat exchange plate 1 and the battery pack 4, there is no need to disassemble and repair the battery pack 4 as a whole, which greatly reduces maintenance costs. On the other hand, it avoids repeatedly plugging and unplugging the pipe joints of the heat exchange plate when disassembling and assembling the battery pack 4, reducing the difficulty of disassembling and assembling the battery pack 4, and is especially more suitable for automated disassembly and assembly equipment of the battery pack 4.

[0020] In a preferred embodiment, such as Figure 2-3 as well as Figure 6-7 As shown, the heat exchange plate 1 is rotatably mounted, and the drive mechanism 2 can push the heat exchange plate 1 to deflect and press it against the battery pack 4. The drive mechanism 2 includes a guide surface 6 on the inner wall of the battery pack 4 accommodating space 3 compartment cover 5. The end of the heat exchange plate 1 extends to the compartment cover 5, and the end of the heat exchange plate 1 abuts against the guide surface 6. When the compartment cover 5 is closed, the heat exchange plate 1 is in a horizontal state and is pressed against the surface of one side of the battery pack 4, allowing heat exchange between the heat exchange plate 1 and the battery pack 4. When it is necessary to remove the battery pack 4, the compartment cover 5 is opened, and one end of the heat exchange plate 1 slides from top to bottom under the influence of gravity, changing from a horizontal state to an inclined state. At this time, the pressing force of the heat exchange plate 1 on the battery pack 4 disappears, and the battery pack 4 can be easily pulled out. Similarly, when it is necessary to install the battery pack 4, the battery pack 4 is pushed in and then the compartment cover 5 is closed. At this time, the guide surface 6 on the inner wall of the compartment cover 5 pushes the end of the heat exchange plate 1 to slide from bottom to top until it returns to a horizontal state and presses against the surface of the battery pack 4. This solution achieves the natural clamping and separation between the heat exchange plate 1 and the battery pack 4 by opening and closing the cover 5 during the assembly and disassembly of the battery pack 4. It has a simple structure, low supporting cost, high stability, long service life and strong practicality.

[0021] In a preferred embodiment, the horizontally arranged heat exchange plate 1 is vertically lifted and moved within the accommodating space 3 via a guide structure, and the heat exchange plate 1 is pushed to contact the surface of the battery pack 4 by a drive mechanism 2. This method can ensure that the pressure at each position is more uniform after the battery pack 4 and the heat exchange plate 1 are in contact, thereby ensuring heat exchange efficiency.

[0022] In a further embodiment, the drive mechanism 2 is a wedge mechanism, including a horizontally slidable slider 10 and wedges 8 fixedly mounted on the opposing surfaces of the slider 10 and the heat exchange plate 1, respectively. The inclined surfaces of the two wedges 8 abut against each other and slide in cooperation. When replacing the battery pack 4, after opening the compartment cover 5, the pressure on the end of the slider 10 disappears, and the heat exchange plate 1 falls naturally away from the battery pack 4 under gravity, pushing the wedges 8 between the heat exchange plate 1 and the slider 10 to move relative to each other in a direction away from each other. At this time, the slider 10 slides outward from the accommodating space 3, and the heat exchange plate 1 moves closer to the slider 10. Similarly, after replacing the battery pack 4, the compartment cover 5 is closed. At this time, the slider 10 is pushed to slide inward, and the wedge 8 between the heat exchange plate 1 and the slider 10 moves relative to each other in a direction that brings them closer together, pushing the heat exchange plate 1 to rise vertically and come into contact with the surface of the battery pack 4. The structure of the vertical drive mechanism 2 is optimized, requiring less installation space, with a simpler structure and a lower failure rate.

[0023] In a further embodiment, a rebounder 7 is arranged at the end of the slider 10 away from the opening of the accommodating space 3 for pushing the slider 10 to reset. After the accommodating space 3 opens the cover 5, the rebounder 7 pushes the slider 10 to reset. Compared with using the gravity of the heat exchange plate 1 to descend or actively pulling the slider 10 to reset by the hook, this is faster and helps to speed up the battery swapping process.

[0024] In a preferred embodiment, the rebounder 7 is a press-type self-locking rebounder 7. When the cover 5 of the accommodating space 3 is closed, after pushing the slider 10 to move inward into place, the rebounder 7 self-locks, locking the position of the slider 10, so that the slider 10 is completely retracted into the accommodating space 3. After pressing the rebounder 7 again, the self-locking is released, and the rebounder 7 pushes the slider 10 to reset. This ensures that when performing other related battery pack 4 or accommodating space 3 maintenance operations, the slider 10 will not immediately pop out after opening the cover 5, avoiding affecting the maintenance work of the operator. It also allows for more flexible and free control of the separation and attachment of the heat exchange plate 1 and the battery pack 4.

[0025] In a preferred embodiment, such as Figure 4-5 As shown, the heat exchange plate 1 is connected to the support structure via the mounting bracket 9, and a buffer 8 is provided between the heat exchange plate 1 and the mounting bracket 9. When the drive mechanism 2 pushes the heat exchange plate 1 and the battery pack 4 to press together, the buffer 8 is compressed by force. When the heat exchange plate 1 and the battery pack 4 bracket are pressed together, the buffer 8 (e.g., a rubber gasket) buffers the pressing force between the heat exchange plate 1 and the battery pack 4. On the one hand, it ensures that the two have sufficient pressing force to make full contact and ensure the heat exchange effect. On the other hand, it avoids excessive pressing force that may cause the heat exchange plate 1 to deform, thereby affecting the fit in some areas and affecting the heat exchange effect.

[0026] In addition, this utility model also provides a battery compartment that can be directly mounted under the vehicle chassis. It includes at least one battery pack slot, and each battery pack slot has a temperature control structure as described above. The design is for the heat exchange requirements of multiple battery packs 4 in the battery compartment. Each slot in the battery compartment is provided with a corresponding heat exchange plate 1. When the battery compartment cover is opened and closed, multiple guide surfaces provided on the inner wall of the battery compartment cover cooperate with the ends of each heat exchange plate 1 to achieve the deflection of the heat exchange plate 1 in each slot and the internal battery pack.

[0027] This utility model also provides a battery-swapping new energy vehicle, including a vehicle body with a battery compartment as described above installed on the vehicle body. For battery-swapping vehicles, the core of battery swapping is the removal of the old battery pack and the insertion of the new battery pack, which requires repeated separation and compression operations between the heat exchange plate and the battery pack. By matching the temperature control structure described above with the battery compartment on the vehicle body, the battery pack replacement operation of the battery-swapping new energy vehicle can be realized, greatly improving the user's battery swapping experience, while ensuring the temperature control effect of the battery pack and improving the charging and discharging efficiency of the battery pack.
