Description

Technical Field

[0001] This application relates to the field of vehicle battery swapping technology, and in particular to a battery swapping support device. Background Technology

[0002] During the battery swapping process, taking heavy-duty trucks as an example, a battery swapping undercarriage device is often used to install the battery box on the heavy-duty truck, thereby ensuring the safety and convenience of the subsequent battery swapping process.

[0003] In related technologies, the battery swapping base device includes a frame and at least four limiting posts and at least four positioning posts disposed on the frame. The limiting posts are distributed around the perimeter of the frame, and each limiting post has a guide portion at its top. It also includes multiple locking elements and multiple driving elements disposed on the frame, with each driving element controlling the movement of a corresponding locking element. When the battery box is placed on the battery swapping base device, the limiting posts are inserted into the bottom of the battery box to provide guidance through the multiple guide portions. Under the action of the positioning posts, the battery box is positioned relatively accurately on the frame. The limiting posts then provide a limiting effect on the battery box, and the driving elements control the locking elements to lock the battery box, ensuring its stability.

[0004] However, the aforementioned battery swapping base device uses multiple driving components to control multiple locking components to lock the battery box, resulting in poor synchronization of the actions of each locking component; furthermore, when the driving components are subsequently repaired, multiple driving components need to be repaired, making the repair process quite difficult. Utility Model Content

[0005] This application provides a battery swapping base device to solve the problems of poor synchronization of locking mechanism operation and high maintenance difficulty in the prior art.

[0015] In one possible implementation, the elastic pusher is a spring, which is coaxially sleeved on the guide rod, with its two ends abutting against the first transmission member and the guide sleeve, respectively.

[0016] In one possible implementation, the drive member is provided with a floating joint, and the drive member is connected to the first transmission member through the floating joint.

[0020] This application provides a battery swapping base device, comprising: a frame body for supporting a battery box; and at least one locking mechanism, the locking mechanism including a driving component, a transmission assembly, and at least two locking elements. The driving component is disposed on the frame body, and drives the at least two locking elements to move through the transmission assembly, thereby clamping the battery box onto the frame body. Therefore, in use, after the battery box is installed on the battery swapping base device, the driving component drives multiple locking elements through the transmission assembly to synchronously lock the battery box onto the frame body. At this time, the synchronization between the locking elements is high, resulting in better locking efficiency and effect for the battery box. Furthermore, only a small number of driving components need to be inspected subsequently, greatly reducing the difficulty and time of maintenance, and solving the problems of poor synchronization of locking element movement and high maintenance difficulty.

[0038] The accompanying drawings illustrate specific embodiments of this application, which will be described in more detail below. These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0039] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0040] In related technologies, the battery swapping base device includes a frame and at least four limiting posts and at least four positioning posts disposed on the frame. The limiting posts are distributed around the perimeter of the frame, and each limiting post has a guide portion at its top. It also includes multiple locking components and multiple driving components disposed on the frame, with each driving component controlling the movement of its respective locking component. When the battery box is placed on the battery swapping base device, the limiting posts are inserted into the bottom of the battery box to guide its placement via the multiple guide portions. Under the action of the positioning posts, the battery box is positioned relatively accurately on the frame. At this time, the limiting posts also limit the battery box, preventing it from flipping or tilting. Furthermore, the driving components control the locking components to lock the battery box, ensuring its stability.

[0041] However, the aforementioned battery swapping base device uses multiple driving components to control multiple locking components to lock the battery box, resulting in poor synchronization of the actions of each locking component. Furthermore, during subsequent maintenance of the driving components, multiple driving components need to be inspected sequentially, making maintenance quite difficult.

[0042] Therefore, this application provides a battery swapping base device, including: a frame body for supporting the battery box; and at least one locking mechanism, which includes a driving member, a transmission assembly, and at least two locking members. The driving member is disposed on the frame body, and drives the at least two locking members to move through the transmission assembly, so that the locking members clamp the battery box onto the frame body. Thus, in use, after the battery box is installed on the battery swapping base device, the driving member drives multiple locking members through the transmission assembly to synchronously lock the battery box onto the frame body. At this time, the synchronization between the locking members is high, resulting in better locking efficiency and effect for the battery box. Furthermore, only a small number of driving members need to be inspected subsequently, greatly reducing the difficulty and time of maintenance, and solving the problems of poor synchronization of locking member movements and high maintenance difficulty.

[0043] The technical solution of this application and how the technical solution of this application solves the above-mentioned technical problems are described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this application will now be described with reference to the accompanying drawings.

[0044] like Figure 1 and Figure 2 As shown in the figure, an embodiment of this application provides a battery swapping base device, comprising:

[0045] The frame body 100 is used to support the battery box 10;

[0046] At least one locking mechanism 300 is provided. The locking mechanism 300 includes a drive member 310, a transmission assembly 330 and at least two locking members 320. The drive member 310 is disposed on the frame body 100. The drive member 310 drives the at least two locking members 320 to move through the transmission assembly 330 so that the locking members 320 clamp the battery box 10 onto the frame body 100.

[0047] During implementation, the frame body 100 can be fixed to the vehicle frame, so that the frame body 100 can be used to support the battery box 10, thereby completing the assembly of the battery box on the vehicle frame.

[0048] In this embodiment, two locking mechanisms 300 are disposed on the frame body 100. Each locking mechanism 300 includes a driving member 310, a transmission assembly 330, and two locking members 320. The driving member 310 can be fixed to the frame body 100 by welding, screwing, or other means. The movable end of the driving member 310 is connected to the two locking members 320 through the transmission assembly 330, so that the driving member 310 can simultaneously control the movement of the two driving members 310, thereby improving the synchronization and consistency between the locking members 320.

[0049] Two locking members 320 are distributed on opposite sides of the driving member 310. The locking members 320 are movably mounted on the frame body 100, and the driving member 310 can then simultaneously control the movement of at least two locking members 320. Alternatively, the locking members 320 can be directly mounted on the driving member 310, so that the driving member 310 can control the movement of at least two locking members 320.

[0050] In use, after the battery box 10 is installed on the battery swapping base device, the drive component 310 drives multiple locking components 320 through the transmission assembly 330 to synchronously lock the battery box 10 onto the frame body 100. At this time, the synchronization between the locking components 320 is high, resulting in better locking efficiency and effect for the battery box 10. In addition, only a small number of drive components 310 need to be inspected and repaired, greatly reducing the difficulty and time of maintenance, and solving the problem of poor synchronization of locking component actions and high maintenance difficulty. Furthermore, compared with existing battery swapping base devices, it is possible to reduce the number of drive components 310 while setting the same number of locking components 320, achieving a lightweight battery swapping base device and saving costs.

[0051] In other embodiments, the number of locking mechanisms 300 (e.g., one or three) and the number of locking elements 320 in the same locking mechanism 300 (e.g., one or three) can be reasonably set according to actual needs.

[0052] like Figure 2 and Figure 3 As shown, the battery swapping base device also includes at least two limiting posts 200, which are disposed on the frame body 100. The limiting posts 200 are used to insert the battery box 10. The top of the two limiting posts 200 has a guide portion 210, and the limiting posts 200 with guide portions 210 are diagonally distributed on the frame body 100.

[0053] In this embodiment, four limiting posts 200 are provided and distributed at the four corners of the frame body 100. Among them, two of the limiting posts 200 have guide portions 210 at their tops, and the limiting posts 200 with guide portions 210 are diagonally distributed on the frame body 100.

[0054] The guide portion 210 has a frustoconical structure so that the guide portion 210 has at least two inclined guide surfaces for contacting the battery box 10.

[0055] In this embodiment, the guide portion 210 has two inclined guide surfaces, one of which corresponds to the wide edge of the frame body 100, and the other guide surface corresponds to the long edge of the frame body 100.

[0056] It should be noted that the bottom of the battery box 10 needs to be provided with insertion holes for the limiting posts 200, so that each limiting post 200 is inserted into the corresponding insertion hole. Furthermore, before the limiting post 200 is inserted into the insertion hole, the guide part 210 will first contact the edge of the insertion hole, so that the guide surface has a better guiding effect on the falling process of the battery box 10, allowing each limiting post 200 to be accurately inserted into the insertion hole at the bottom of the battery box 10, thereby limiting the battery box 10 from flipping or tilting.

[0057] In use, when the battery box 10 is installed on the battery swapping base device, the battery box 10 can be guided by the two diagonally arranged guide parts 210, so that the battery box 10 can be accurately placed on the frame body 100, and the battery box 10 can cooperate with each limiting post 200, so that each limiting post 200 has a better limiting effect on the battery box 10, thereby ensuring better guiding accuracy and load-bearing capacity for the battery box 10.

[0058] Secondly, the driving component 310 simultaneously drives multiple locking components 320 to lock the battery box 10 onto the frame body 100. This ensures better guiding accuracy and load-bearing capacity for the battery box 10 while significantly reducing the number of guide parts 210 and driving components 310 in the battery swapping base device, achieving a lightweight design and reducing costs.

[0059] like Figure 2 and Figure 3 As shown, in some embodiments, the frame body 100 is provided with a plurality of positioning members 400, which are used to insert the battery box 10 to position the battery box 10.

[0060] The positioning element 400 can be a pin-shaped, platform-shaped, or block-shaped structure, and there are no restrictions on this. The positioning element 400 can be fixed to the frame body 100 by screwing, welding, or other means, and the positioning element 400 is arranged vertically.

[0061] It should be noted that, during implementation, insertion holes can also be made at the bottom of the battery box 10 corresponding to the positioning member 400. After the battery box 10 is placed on the frame body 100, the positioning member 400 will be inserted into the battery box 10 to accurately position the battery box 10 and further ensure the installation accuracy of the battery box 10.

[0062] In this embodiment, two positioning elements 400 are provided, and the two positioning elements 400 are diagonally distributed on the frame body 100. Compared with the existing battery swapping base device, while ensuring better installation accuracy for the battery box 10, the number of positioning elements 400 is reduced, thus achieving a lightweight battery swapping base device. In other embodiments, three or four positioning elements 400 may be provided.

[0063] like Figure 3As shown, in some embodiments, the frame body 100 may include multiple crossbeams 110 and multiple connecting beams 120. Specifically, two crossbeams 110 and two connecting beams 120 may be provided, with the two crossbeams 110 parallel to each other and the two connecting beams 120 parallel to each other. The crossbeams 110 may be connected to the connecting beams 120 by welding, screwing, or other means, and the extension direction of the crossbeams 110 is perpendicular to the extension direction of the connecting beams 120. The connecting beams 120 are used to connect to the vehicle frame, and the crossbeams 110 are used to connect to the battery box 10.

[0064] Meanwhile, multiple gaskets 111 can be welded to the upper surface of the crossbeam 110 to adjust the flatness of the upper surface of the crossbeam 110 or to contact the bottom of the battery box 10. A number of mounting beams 112 can also be welded between the two crossbeams 110 to facilitate the mounting of connectors for connection to the battery box 10 on the mounting beams 112, i.e., to provide mounting points for the connectors via the mounting beams 112.

[0065] In addition, other auxiliary beams 113 or mounting plates 114 can be welded onto the crossbeam 110 as needed to provide mounting locations for other mechanisms required later. For example, the required locking hook mechanism can be installed on the auxiliary beam 113, and the water cooling mechanism can be installed on the mounting plate 114; of course, other mechanisms can be installed on the auxiliary beam 113 or mounting plate 114, and the mechanisms here can be assembled by referring to the composition of the existing battery swapping base device.

[0066] The cross sections of the crossbeam 110, connecting beam 120, mounting beam 112, or auxiliary beam 113 can be reasonably set according to actual needs, that is, set to different shaped cross sections or hollow interiors, so as to ensure lightweight while meeting strength requirements and high-capacity battery swapping requirements.

[0067] like Figure 2 and Figure 4 As shown, in some embodiments, the locking member 320 is rotatably connected to the frame body 100. The locking member 320 has a clamping part 321. The driving member 310 drives the locking member 320 to rotate through the transmission assembly 330 so that the clamping part 321 clamps the battery box 10 onto the frame body 100.

[0068] In this embodiment, two locking members 320 are distributed on opposite sides of the driving member 310 along the width direction of the frame body 100. The locking members 320 can be block-shaped, plate-shaped, column-shaped, or other shapes, and there is no limitation thereto. The lower end of the locking member 320 can be rotatably connected to the frame body 100 via a pivot, and the upper end of the locking member 320 has a clamping part 321. The clamping part 321 can be integrally formed from the locking member 320, or it can be fixed to the locking member 320 by welding, screwing, or other means. At this time, controlling the rotation of the locking member 320 can cause the clamping part 321 to clamp the battery box 10 onto the frame body 100, or release the clamping of the battery box 10.

[0069] It should be noted that, in practice, the inner side of the bottom of the battery box 10 often has a flange to provide a clamping part for the clamping part 321. That is, the clamping part 321 clamps the flange to the frame body 100, thereby clamping the battery box 10 onto the frame body 100.

[0070] The driving component 310 can be a pneumatic cylinder or a hydraulic cylinder, giving it a cylinder body and a piston rod. The specific structure of the driving component 310 can be designed with reference to existing products, and the model is not limited. The movable end of the driving component 310 (i.e., the piston rod on the driving component 310) is simultaneously connected to the two locking components 320.

[0071] In use, the driving component 310 simultaneously drives the two locking components 320 to rotate, thereby causing the clamping part 321 to clamp the bottom of the battery box 10 onto the frame body 100, ensuring the stability of the battery box 10 after installation.

[0072] like Figure 4 As shown, in some embodiments, the transmission assembly 330 includes a first transmission member 331 and at least two second transmission members 332;

[0073] Each second transmission component 332 is rotatably connected to the first transmission component 331, and each second transmission component 332 is rotatably connected to each locking component 320.

[0074] The first transmission component 331 is connected to the driving component 310, and the driving component 310 is used to control the movement of the first transmission component 331.

[0075] In this embodiment, the first transmission component 331 includes a connecting plate 3311 and a connecting rod 3312. The connecting rod 3312 can be fixed to the connecting plate 3311 by welding, screwing, or other means. The connecting plate 3311 is connected to the movable end of the driving component 310. This allows the driving component 310 to drive the first transmission component 331 to reciprocate as a whole.

[0076] In other embodiments, the first transmission member 331 may also be rod-shaped, plate-shaped, block-shaped, or other structures.

[0077] The second transmission member 332 can be rod-shaped, strip-shaped, tubular, or other shapes, and there is no limitation thereto. In this embodiment, the second transmission member 332 is rod-shaped, and each second transmission member 332 is correspondingly disposed on each locking member 320. The two ends of the second transmission member 332 are respectively rotatably connected to the upper end of the locking member 320 and the connecting rod 3312 in the first transmission member 331 through a rotating shaft.

[0078] Thus, during the process of the drive member 310 controlling the first transmission member 331 to reciprocate, the second transmission member 332 can drive the locking member 320 to reciprocate, thereby clamping the bottom of the battery box 10 onto the frame body 100, ensuring the stability of the battery box 10 after installation, or releasing the clamping of the battery box 10.

[0079] like Figure 4 As shown, the locking mechanism 300 further includes at least one guide component 340, which includes a guide rod 341 and a guide sleeve 342. The guide sleeve 342 is disposed on the frame body 100 or the drive member 310. The guide rod 341 is connected to the first transmission member 331 and passes through and is slidably connected to the guide sleeve 342.

[0080] In this embodiment, two guide components 340 are provided, and the two guide components 340 are located on opposite sides of the drive component 310. Of course, the number of guide components 340 can also be other, such as one or three.

[0081] The guide sleeve 342 is annular and can be fixed to the cylinder in the drive member 310 or to the frame body 100 by screwing, welding or other means. The extension direction of the guide rod 341 is parallel to the extension direction of the piston rod in the drive member 310. One end of the guide rod 341 can be connected to the connecting plate 3311 in the first transmission member 331 by screwing, welding or other means, and the other end of the guide rod 341 passes through and is slidably connected to the guide sleeve 342.

[0082] Therefore, during the process of the drive member 310 controlling the movement of the first transmission member 331 and the second transmission member 332, the first transmission member 331 will pull the guide rod 341 to slide relative to the guide sleeve 342, so that the guide rod 341 has a guiding and supporting effect on the movement of the first transmission member 331, thereby improving the stability of the first transmission member 331 and the second transmission member 332 during movement, and further improving the stability of the locking member 320 during rotation.

[0083] like Figure 4As shown, the locking mechanism 300 further includes at least one elastic pusher 350, one end of which is connected to the first transmission member 331, and the other end of which is connected to the drive member 310, the guide sleeve 342 or the frame body 100.

[0084] Understandably, when the drive member 310 controls the first transmission member 331 to rise, it will drive the locking member 320 to clamp the battery box 10; when the drive member 310 controls the first transmission member 331 to fall, it will drive the locking member 320 to release the clamping of the battery box 10.

[0085] At this time, the elastic pusher 350 can drive the first transmission member 331 to maintain an upward trend, so that when the drive member 310 stops working, the first transmission member 331 can also be kept in the current position under the action of the elastic pusher 350, so that the locking member 320 can maintain a clamping effect on the battery box 10.

[0086] like Figure 4 As shown, specifically, the elastic pusher 350 is a spring, which is coaxially sleeved on the guide rod 341. The two ends of the spring abut against the connecting plate 3311 and the guide sleeve 342 in the first transmission member 331, respectively.

[0087] In practice, the spring is first compressed and then installed onto the guide rod 341, thus ensuring that the spring maintains optimal thrust on the first transmission component 331. Furthermore, during operation, the guide rod 341 provides excellent guidance and support for the spring, reducing the likelihood of the spring's performance being reduced due to bending.

[0088] In other embodiments, one end of the spring may be connected to the first transmission member 331, and the other end of the spring may be connected to the drive member 310 or the frame body 100. Furthermore, the elastic pusher 350 may also be an elastic sheet.

[0089] like Figure 4 As shown, in some embodiments, the drive member 310 is provided with a floating joint 360, and the drive member 310 is connected to the first transmission member 331 through the floating joint 360.

[0090] The floating joint 360 can be an existing product, and the movable end of the drive component 310 is connected to the connecting plate 3311 in the first transmission component 331 through the floating joint 360. This reduces the direct impact force on the drive component 310, provides a certain degree of protection for the drive component 310, and extends its service life.

[0091] During installation, for example, the floating joint 360 can be connected to the movable end of the drive member 310 by screwing, welding or other means. The connecting plate 3311 is provided with a stepped groove at one end facing the drive member 310, and the floating joint 360 is snapped into the stepped groove.

[0092] In other embodiments, the locking member 320 may also be slidably disposed on the frame body 100. In this case, the driving member 310 is used to control at least two locking members 320 to slide so as to clamp the battery box 10.

[0093] In summary, the battery swapping base device provided in this application embodiment, when in use, after the battery box 10 is installed on the battery swapping base device, the driving component 310 drives multiple locking components 320 to lock the battery box 10 onto the frame body 100 in a synchronized manner. At this time, the synchronization between the locking components 320 is high, and the locking efficiency and locking effect of the battery box 10 are better. In addition, only a small number of driving components 310 need to be inspected and repaired in the future, which greatly reduces the difficulty and time of inspection and repair, and solves the problem of poor synchronization of the locking component action and high difficulty of inspection and repair.
