Description

Technical Field

[0001] This utility model relates to the field of battery swapping station technology, specifically to a support frame and a battery swapping station. Background Technology

[0002] Safety during heavy-duty truck battery swapping has always been a key concern for customers, with fire safety being a crucial aspect. Currently, the common fire safety measure is to install a fire compartment inside the battery swapping station. In the event of a thermal runaway battery, it is transferred to the fire compartment, isolating it from other batteries and thus achieving a fire suppression effect. However, this method of installing the fire compartment is attached to the station canopy, increasing the footprint and leading to difficulties in obtaining land approvals and higher costs for customers. Furthermore, as battery swapping stations evolve from traditional fixed bays to expandable models, the presence of the fire compartment limits the station's expansion to one direction, imposing stringent site requirements and restricting application scenarios, thus increasing the difficulty of site selection for battery swapping. Utility Model Content

[0003] The purpose of this invention is to at least solve the problem of the large footprint of existing battery swapping stations due to the installation of fire-fighting compartments. This objective is achieved through the following technical solution:

[0004] The first aspect of this utility model provides a support bracket for a battery swapping station, the support bracket comprising:

[0005] The main body is used to be installed on the outside of the battery swapping station. The main body includes a fixing part and a swing arm rotatably disposed on the fixing part. The swing arm has a first state and a second state. In the first state, the swing arm extends along a first direction to allow passage of the driveway of the battery swapping station. In the second state, the swing arm extends along a second direction to block the driveway and to carry the thermal runaway battery of the battery swapping station. The second direction is at an angle to the first direction.

[0006] A drive assembly is disposed on a fixed part and is connected to the swing arm via a transmission to enable the main body to switch between the first state and the second state.

[0007] The support bracket described in this utility model, by placing the main body on the outside of the battery swapping station to support the thermal runaway battery, achieves the isolated placement of the thermal runaway battery from other batteries. This allows the fire compartment to be located outside the battery swapping station, helping to reduce the internal space and improve the station's versatility. Simultaneously, by configuring the main body and drive assembly, the swing arm has a first state and a second state. In the second state, the swing arm is in a working position to receive the thermal runaway battery output from inside the battery swapping station. In the first state, the swing arm is in a standby position extending along a first direction.

Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

[0048] It should be understood that the terminology used herein is for the purpose of describing particular exemplary embodiments only and is not intended to be limiting. Unless the context clearly indicates otherwise, the singular forms “a,” “an,” and “described” as used herein may also mean including the plural forms. The terms “comprising,” “including,” “containing,” and “having” are inclusive and therefore indicate the presence of the stated features, steps, operations, elements, and / or components, but do not exclude the presence or addition of one or more other features, steps, operations, elements, components, and / or combinations thereof. The method steps, processes, and operations described herein are not construed as requiring them to be performed in a particular order described or illustrated unless the order of performance is explicitly indicated. It should also be understood that additional or alternative steps may be used.

[0049] Although terms such as first, second, third, etc., may be used in this document to describe multiple elements, components, regions, layers, and / or segments, these elements, components, regions, layers, and / or segments should not be limited by these terms. These terms may be used only to distinguish one element, component, region, layer, or segment from another. Unless the context clearly indicates otherwise, terms such as "first," "second," and other numerical terms used herein do not imply order or sequence. Therefore, the first element, component, region, layer, or segment discussed below may be referred to as the second element, component, region, layer, or segment without departing from the teachings of the exemplary embodiments.

[0050] For ease of description, spatial relative terms may be used in the text to describe the relationship of one element or feature relative to another element or feature, as shown in the figure. These relative terms include, for example, "inside," "outside," "middle," "outer," "below," "below," "above," "over," etc. Such spatial relative terms are intended to include different orientations of the device in use or operation, other than those depicted in the figure. For example, if the device in the figure is flipped, an element described as "below other elements or features" or "below other elements or features" would subsequently be oriented "above other elements or features" or "above other elements or features." Therefore, the example term "below" can include both upper and lower orientations.

[0051] Currently, the most common fire protection measure in the market is to install a fire compartment inside the fire station canopy. When a thermal runaway battery is encountered, it is transferred to the fire compartment to isolate it from other batteries, thus achieving a fire-fighting effect. However, this method of installing the fire compartment is attached to the fire station canopy, increasing the footprint and leading to difficulties in obtaining land use approvals and higher site construction costs for customers. Furthermore, the presence of the fire compartment inside the canopy makes it impossible to standardize the form and size of the fire station canopy for both internal and external fire protection, hindering its versatility. In addition, as fire stations evolve from traditional fixed compartments to expandable models, the presence of the fire compartment limits expansion to one direction, imposing stringent site requirements and restricting application scenarios, thus increasing the difficulty of site selection.

[0052] like Figures 1-5 As shown, this utility model proposes a support bracket 100 for use in battery swapping stations, which helps to solve the problem of large floor space required by existing battery swapping stations due to the installation of fire compartments. Among other things, Figure 1 and Figure 2 The schematic diagram illustrates the structure of the support bracket 100 provided by this utility model in two states. Figures 3 to 5 This is a partial structural diagram of the support bracket 100 provided by this utility model.

[0053] In terms of overall design, the support bracket 100 includes a main body and a drive assembly 30. The main body is used for installation on the outside of the battery swapping station. Specifically, the main body includes a fixing part 20 and a swing arm 10 rotatably mounted on the fixing part 20. The swing arm 10 has a first state and a second state. In the first state, the swing arm 10 extends along a first direction a to allow passage through the battery swapping station's driveway. In the second state, the swing arm 10 extends along a second direction b to block the driveway and support the thermal runaway battery of the battery swapping station. The second direction b is angled relative to the first direction a. The drive assembly 30 is mounted on the fixing part 20 and is drive-connected to the swing arm 10 to allow the main body to switch between the first and second states.

[0054] Specifically, by placing the main body on the outside of the battery swapping station to support the thermal runaway battery, the thermal runaway battery is isolated from other batteries, thus allowing the fire compartment to be located outside the battery swapping station. This helps reduce the internal space of the battery swapping station and improves its versatility. Simultaneously, by configuring the main body and drive assembly 30, the swing arm 10 has a first state and a second state. In the second state, the swing arm 10 is in a working position to receive the thermal runaway battery output from inside the battery swapping station. In the first state, the swing arm 10 is in a standby position extending along the first direction a. This effectively reduces the commonly used area of ​​the battery swapping station and reduces the impact of the support bracket 100 on battery swapping operations and vehicle movement, helping to solve the problem of large footprint caused by the installation of the fire compartment in existing battery swapping stations.

[0055] It is understood that the main body includes a fixing part 20 and a swing arm 10. The fixing part 20 can serve as the mounting base for the swing arm 10, directly fixed to the foundation. In this case, the fixing part 20 is a one-piece molded component with good reliability, ensuring that it will not shift or sway due to the weight of the battery. The fixing part 20 can also serve as a connecting structure. Optionally, the fixing part 20 can be connected and fixed to the enclosure of the battery swapping station, which helps reduce the installation difficulty of the support bracket 100 and ensures that the fixing part 20 will not affect the load-bearing capacity of the thermal runaway battery.

[0056] It should be noted that when the fixing part 20 is connected to the housing as a connecting structure, the fixing part 20 can be a single molded part, or multiple parts can be provided. For example... Figures 1-4 As shown, there are multiple fixing parts 20, and each fixing part 20 may be the same or different. Each mounting part 20 can install a component alone, or it can cooperate with other mounting parts 20 to install a component. Correspondingly, the housing is provided with a mounting structure that connects to the fixing part 20. Optionally, the mounting structure and the fixing part 20 are configured as a flange-like structure.

[0057] Still Figures 1-4 As shown, the swing arm 10 is rotatably mounted on the fixed part 20 and connected to the housing via at least two fixed parts 20. Optionally, one or two swing arms 10 can be provided, and the rotation axis of the swing arm 10 can be arranged in a vertical or horizontal direction. Figure 1 and Figure 2 As shown, in this embodiment, two swing arms 10 are provided, and the rotation axes of both swing arms 10 are arranged in the vertical direction. The fixing part 20 includes two first mounting parts 21 and two second mounting parts 22, wherein the first mounting parts 21 and the second mounting parts 22 may be the same or different. One swing arm 10 passes through both a first mounting part 21 and a second mounting part 22, and the first mounting parts 21 and the second mounting parts 22 are spaced apart in the vertical direction, so that the rotation axis of the swing arm 10 is arranged in the vertical direction.

[0058] The swing arm 10 has a first state and a second state, and correspondingly, the support bracket 100 has a standby state and an operating state. When the swing arm 10 is in the first state, it extends along a first direction a, and is in the standby position. When the swing arm 10 is in the second state, it extends along a second direction b to support the thermal runaway battery of the battery swapping station, and is in the operating position. Furthermore, the second direction b is at an angle to the first direction a.

[0059] In this embodiment, the fixing part 20 is connected to the casing of the battery swapping station, and the fixing part 20 is located below the battery swapping window of the casing. The battery can pass through the battery swapping window along the second direction b to achieve battery storage and output, thereby completing the purpose of battery swapping for heavy trucks. When the main body is in the second state, the swing arm 10 extends along the second direction b. At this time, the second direction b is perpendicular to the vehicle's driving direction, which seriously affects the vehicle's driving and battery swapping. When the main body is in the first state, the swing arm 10 extends along the first direction a. The second direction b is angled to the first direction a, so that the main body will not affect the vehicle's driving and normal battery swapping operations when in standby mode. Optionally, the second direction b is perpendicular to the first direction a, where the first direction a is the vehicle's driving direction before and after battery swapping.

[0060] At this time, the drive assembly 30 is mounted on the fixed part 20 and is connected to the swing arm 10 for transmission, so that the main body switches between the first state and the second state. By setting the drive assembly 30 to realize the automatic switching of the main body's state, it helps to improve the ease of use of the support bracket 100 and helps to reduce the footprint of the support bracket 100 in conjunction with the main body, thereby helping to reduce the footprint of the battery swapping station.

[0061] What needs further understanding is, such as Figure 1 and Figure 2 As shown, in this embodiment, the two swing arms 10 are respectively arranged on opposite sides of the fixed part 20 along the first direction a. In the first state, the two swing arms 10 are located on the same straight line, and the rotation directions of the two swing arms 10 are opposite, and the rotation amplitude is mirror-symmetrical about the fixed part 20. In the second state, the two swing arms 10 are arranged in parallel and are located on the same side of the fixed part 20 along the second direction b. This arrangement helps to further reduce the floor space occupied by the support bracket 100 in the first state, and improve the support effect for the thermal runaway battery in the second state.

[0062] It should be noted that when the support bracket 100 is in the first state, the two swing arms 10 can be set to be parallel in addition to being on the same straight line. In this case, the two swing arms 10 have the same rotation angle and the rotation amplitude has an overlapping part, but the area occupied is larger than the above scheme and it is easy to affect the driving of the vehicle.

[0063] Furthermore, the drive assembly 30 includes a drive motor 31 and a transmission mechanism 32. The drive motor 31 is mounted on the fixed part 20, and the transmission mechanism 32 is connected to the drive end of the drive motor 31, and the transmission mechanism has a transmission end that is hinged to the two swing arms 10 respectively.

[0064] Specifically, by setting up a drive motor 31 and a transmission mechanism 32, and connecting the transmission mechanism 32 to the two swing arms 10 respectively, it is helpful to achieve synchronous control of the two swing arms 10, thereby helping to ensure the accuracy of the movement of the swing arms 10 and improve the support effect of the support bracket 100 on the thermal runaway battery.

[0065] It should be understood that in this embodiment, the fixing part 20 further includes a fourth fixing part 24. The drive motor 31 is mounted on the fourth fixing part 24, and the output end of the drive motor 31 is provided with a transmission mechanism 32. The transmission mechanism 32 has two transmission ends. When the output end of the drive motor 31 is working, the two transmission ends will simultaneously drive the two swing arms 10 to rotate, thereby realizing the switching of the main body between the first state and the second state. The transmission mechanism 32 can use gear transmission, linkage transmission or cam transmission to drive the two swing arms 10, and no restrictions are imposed here.

[0066] In this embodiment, the transmission mechanism 32 includes a mounting post 321, a transmission rod 322, and a connecting rod 323. The fixing part 20 further includes a third fixing part 23, and the mounting post 321 is disposed on the third fixing part 23, extending along the second direction b. Optionally, the mounting post 321 and the fixing part 20 are integrally formed. Figures 1-4 As shown, the middle part of the transmission rod 322 is sleeved on the mounting post 321, thereby enabling it to rotate around the mounting post 321. Meanwhile, the connecting rod 323 has a first end and a second end, and there are two connecting rods 323. The first ends of the two connecting rods 323 are respectively hinged to opposite ends of the transmission rod 322, and the second ends of the two connecting rods 323 are respectively hinged to one of the two swing arms 10. Furthermore, the connecting rods 323 extend along a first direction a, and the drive shaft of the drive motor 31 extends along the first direction a. The drive shaft of the drive motor 31 is hinged to the transmission rod 322, and the drive shaft is located between the mounting post 321 and one of the connecting rods 323.

[0067] When the drive shaft of the drive motor 31 moves along the first direction a, it drives the transmission rod 322 to deflect around the mounting post 321. At this time, the two ends of the transmission rod 322 pull the two connecting rods 323 closer to or further apart along the first direction a. Since the swing arms 10 are rotatably connected through the fixing part 20, when the two connecting rods 323 move closer to or further apart along the first direction a, the two swing arms 10 will move from the standby position to the working position, or from the working position to the standby position, thereby realizing the state switching of the main body. This configuration is simple in structure, easy to install, and has good control effect, which helps to reduce the space occupation rate.

[0068] It should be further understood that the support bracket 100 also includes a first positioning member 50 and a second positioning member 60. Along the second direction b, the first positioning member 50 is located on one side of the fixed part 20 and is spaced apart from the fixed part 20. In the second state, the two opposite ends of the first positioning member 50 abut against the two swing arms 10 respectively along the first direction a. By setting the first positioning member 50, the accuracy of the supporting position of the main body in the second state is improved, ensuring the load-bearing effect on the thermal runaway battery.

[0069] The second positioning member 60 is spaced apart from the fixed part 20 along the first direction a. In the first state, the second positioning member 60 abuts against at least one of the two swing arms 10. In this embodiment, there are two second positioning members 60, which are respectively arranged on opposite sides of the fixed part 20 along the first direction a. By setting the second positioning member 60, the accuracy of the main body's position in the first state can be effectively improved, and it helps to protect the swing arms 10 and prevent the swing arms 10 from damaging the housing. By setting the first positioning member 50 and the second positioning member 60, the use effect of the support bracket 100 can be improved, and the impact on vehicle driving or battery swapping can be reduced.

[0070] In some embodiments of this application, the swing arm 10 is provided with a plurality of support assemblies 40 for supporting the thermal runaway battery, and the plurality of support assemblies 40 are spaced apart along the direction away from the fixed part 20. By providing a plurality of support assemblies 40, the contact area between the swing arm 10 and the battery is reduced, thereby reducing the impact on subsequent fire fighting. At the same time, the provision of a plurality of support assemblies 40 also helps to reduce the weight of the support bracket 100 and reduce manufacturing costs.

[0071] Furthermore, the support assembly 40 includes a support rod 41 and an elastic element 42. The support rod 41 is movably inserted into the swing arm 10 in a vertical direction, and a support plate 411 is provided at the top of the support rod 41. The elastic element 42 is disposed between the support plate 411 and the swing arm 10, and the elastic element 42 has a first compression state that drives the support plate 411 away from the swing arm 10.

[0072] Specifically, by setting the support rod 41 and the elastic element 42, the support assembly 40 can have a certain amount of room for movement in the vertical direction. On the one hand, this effectively reduces the influence of the support assembly 40 on the rotation of the swing arm 10, thereby ensuring the feasibility of the swing arm 10's movement. On the other hand, it also avoids the support assembly 40 directly and quickly bearing the weight of the thermal runaway battery, which would affect the effectiveness of the main support.

[0073] It should be understood that a second connecting member 12 is detachably provided on the swing arm 10, and the second connecting member 12 has a through hole. Optionally, the second connecting member 12 is connected to the swing arm 10 by bolts to ensure the connection effect. In this embodiment, there are two second connecting members 12, which are spaced apart in the vertical direction. The support rod 41 is adapted to be inserted into the two through holes to ensure the accuracy of the installation of the support rod 41. At the same time, the elastic element 42 is set as a spring and is sleeved on the support rod 41. One end of the spring is connected to the swing arm 10, and the other end is connected to the support plate 411. This configuration is simple in structure and easy to install.

[0074] When the two swing arms 10 carry the thermal runaway battery, multiple support rods 41 can move down vertically and abut against the ground, thereby forming a rod structure that carries the thermal runaway battery. The connection of the swing arms 10 forms a square column structure, which helps to ensure the support effect of the support bracket 100.

[0075] Of course, the support component 40 can be configured in other forms besides the structure described above, as long as it can ensure that the support component 40 does not affect the rotation of the swing arm 10.

[0076] It should be further understood that, in this embodiment, a first connecting member 11 is also provided on the swing arm 10, and the first connecting member 11 is fixed to the swing arm 10 by bolts. The first connecting member 11 has a slide groove 101 extending in the vertical direction. The support assembly 40 also includes a limiting member 43, wherein the limiting member 43 is movably disposed in the slide groove 101 and connected to the support rod 41. When the limiting member 43 is located at the top of the slide groove 101, the elastic member 42 is in a first compressed state. The setting of the limiting member 43 helps to prevent the support rod 41 from dislodging from the through hole of the second connecting member 12 located at a lower height. At the same time, in conjunction with the elastic member 42, it helps to further improve the installation effect of the support rod 41 on the swing arm 10. In addition, when the limiting member 43 is located at the bottom of the slide groove 101, if the support rod 41 still has a downward tendency, the limiting member 43 will distribute the gravity to the swing arm 10 and then transfer it to the housing, which helps to further ensure the support effect of the support bracket 100 on the thermal runaway battery.

[0078] Compared with the prior art, the battery swapping station proposed in this utility model has the technical advantages of the aforementioned support bracket 100, which will not be elaborated here.

Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
