[0002] In the design of electric tricycles, the battery compartment is a key component for carrying and protecting the battery module, and its stability and buffering performance are directly related to the safety and reliability of the vehicle. Traditional battery compartment designs often rely only on simple fixed brackets to support the battery modules, which is less effective in dealing with bumps and impacts during driving. Due to the lack of an effective buffering mechanism, the battery module is easily damaged by vibration, which not only affects the service life of the battery, but may also cause safety hazards. Therefore, in order to solve the above problems, the present invention proposes a buffered battery compartment. Summary of the invention

[0003] The object of the present invention is to provide a buffer type battery compartment to solve the problems raised in the above background technology.

[0004] In order to achieve the above-mentioned purpose, the present invention adopts the following technical solution: a buffer type battery compartment, comprising:

[0005] shell;

[0006] Two support seats, the two support seats are symmetrically arranged inside the housing and are used to support the battery module;

[0007] A plurality of buffer components, wherein the plurality of buffer components are distributed on both sides of the inner wall of the shell;

[0008] Each of the buffer components comprises:

[0009] A rotating disk, the rotating disk being rotatably connected to the inner wall of the housing;

[0010] A guide frame, the guide frame is fixed on the inner wall of the shell, and a plurality of guide walls are arranged on the guide frame, and the plurality of guide walls are distributed around the rotating disk;

[0011] A plurality of arc-shaped elastic plates, the plurality of elastic plates are evenly distributed around the rotating disk in the circumferential direction, the inner arc of each of the elastic plates faces the rotating disk, one end of the elastic plate is connected to the rotating disk, and the other end of the elastic plate is slidably connected to the corresponding guide wall;

[0012] A swing frame, the swing frame is fixed on the rotating disk, a downwardly inclined extension rod is fixed on the swing frame, and a connecting shaft for connecting to a support seat is fixed on one end of the extension rod away from the swing frame;

[0013] When the connecting shaft moves downward, it drives the swing frame and the rotating disk to rotate, and one end of the elastic plate slides on the guide wall and gradually approaches the rotating disk, so that the elastic plate produces deformation buffer.

[0014] Preferably, a pressing wall is provided on the side wall of the guide frame corresponding to each guide wall, and the outer arc surface of the elastic plate is movably pressed against the pressing wall.

[0015] Preferably, one end of the elastic plate away from the rotating disk is rotatably connected to a roller, and the roller is rollingly connected to the guide wall.

[0016] Preferably, the buffer assembly further comprises a mounting plate, the mounting plate is rotatably connected to the connecting shaft, a recessed groove is provided on the side wall of the support seat, and the mounting plate is fixed inside the recessed groove by bolts.

[0017] Preferably, a fixing column for supporting the rotating disk is fixed on the inner wall of the shell, and bearings are arranged between the fixing column and the rotating disk and between the connecting shaft and the mounting plate.

[0021] Compared with existing technologies;

[0022] The present invention provides a stable support platform for the battery module by arranging symmetrical support seats inside the shell, thereby ensuring its stability during placement. At the same time, each support seat corresponds to a plurality of buffer components, which are distributed in pairs on both sides of the support seat, thereby achieving uniform and stable support for the support seat, further enhancing the stability of the battery module. Secondly, the rotating disk, elastic plate, guide wall and other structures in the buffer assembly cooperate with each other to form an efficient buffer system. When there is a bumpy force during driving, the elastic plate can undergo elastic deformation to absorb and disperse these impact forces, thereby effectively protecting the battery module from damage.

[0023] The present invention achieves further control over the deformation process of the elastic plate by adding abutment walls to each guide wall on the side wall of the guide frame. When encountering slight bumps, the elastic plate can deform moderately, effectively absorb and disperse the impact energy, and protect the battery module. When encountering larger bumps or impacts, the outer arc surface of the elastic plate will be pressed against the abutment wall, which not only limits the excessive deformation of the elastic plate, but also enhances its elastic strength by adding additional support points. This interaction enables the battery compartment to absorb and disperse energy more effectively when subjected to strong impacts, providing more reliable buffering protection for the battery module.

[0044] The present invention is described below with specific embodiments, but they are not intended to be limiting of the invention.

[0045] Embodiment 1

[0046] like Figure 1-Figure 8 As shown, in this embodiment, a buffer-type battery compartment is provided, including a shell 1, two support seats 2 for supporting the battery module are symmetrically arranged inside the shell 1, and a plurality of buffer components 3 are distributed on both sides of the inner wall of the shell 1; each buffer component 3 includes a rotating disk 301, the rotating disk 301 is rotatably connected to the inner wall of the shell 1, a fixing column 307 for supporting the rotating disk 301 is fixed on the inner wall of the shell 1, and a bearing is arranged between the fixing column 307 and the rotating disk 301; a guide frame 302 is fixed on the inner wall of the shell 1, and a plurality of guide walls 3021 are arranged on the guide frame 302, and the plurality of guide walls 3021 are distributed around the rotating disk 301; a plurality of arc-shaped elastic plates 303 are uniformly distributed around the rotating disk 301 in the circumferential direction, and the inner arc of each elastic plate 303 faces the rotating disk 301, one end of the elastic plate 303 is connected to the rotating disk 301, and the other end of the elastic plate 303 is slidably connected to the corresponding guide wall 3021, as shown in FIG. Figure 5 As shown, a plurality of slots 3011 are circumferentially distributed on the rotating disk 301, a post 3031 is fixed to the end of the elastic plate 303, the post 3031 is inserted into the corresponding slot 3011, and a cover plate 3012 for blocking the end of the slot 3011 is provided on the rotating disk 301; a swing frame 304 is fixed to the rotating disk 301, a downwardly inclined extension rod 3041 is fixed to the swing frame 304, and a connecting shaft 3042 for connecting to the support seat 2 is fixed to the end of the extension rod 3041 away from the swing frame 304.

[0047] When the connecting shaft 3042 moves downward, the swing frame 304 and the rotating disk 301 are driven to rotate, and one end of the elastic plate 303 slides on the guide wall 3021 and gradually approaches the rotating disk 301, so that the elastic plate 303 produces deformation buffer.

[0048] One support seat 2 corresponds to four buffer components 3, and the four buffer components 3 are distributed on both sides of the support seat 2 in pairs. The connecting shafts 3042 on the two buffer components 3 on the same side synchronously support one side of the support seat 2, so that one support seat 2 has four supporting points. There is space for placing the battery module between the two support seats 2. When the battery module is placed in the outer shell 1, the battery module is supported by the two support seats 2. Under the gravity of the battery module, the two support seats 2 will sink to a certain extent.

[0049] Three elastic plates 303 are arranged on a rotating disk 301. Correspondingly, there are also three guide walls 3021 on the guide frame 302. The three guide walls 3021 correspond to the three elastic plates 303 one by one. Figure 4 As shown, the three guide walls 3021 form a triangle, the center of the triangle coincides with the center of the rotating disk 301, and the tangent points of the inscribed circle of the triangle and the three guide walls 3021 are point a, point b, and point c respectively. The straight-line distance between the center of the rotating disk 301 and point a, point b, and point c is the shortest distance between the guide walls 3021. When the rotating disk 301 moves along Figure 4 When rotating in the direction of the arrow shown, the corresponding ends of the elastic plate 303 slide toward point a, point b, and point c respectively, and the elastic plate 303 is deformed during this process.

[0050] When the battery module is placed in the housing 1, the buffer component 3 changes as follows:

[0051] When the battery modules are placed on the two support bases 2, the gravity causes the support bases 2 to sink to a certain extent. Each support base 2 corresponds to four buffer components 3, which are distributed on both sides of the support base 2 in pairs, thereby ensuring that the support base 2 can be supported evenly and stably when subjected to pressure.

[0052] As the gravity of the battery module acts, the connecting shaft 3042 connected to the side wall of the support seat 2 moves downward. This downward movement drives the extension rod 3041 fixed to the connecting shaft 3042 and the swing frame 304 to move together. Since the swing frame 304 is fixed to the rotating disk 301, this movement will eventually cause the rotating disk 301 to rotate. The rotation of the rotating disk 301 causes the three elastic plates 303 uniformly distributed around it to produce certain deformation.

[0053] During the bumping process, the specific principle of buffering the battery module is as follows:

[0054] When the battery module is subjected to up and down forces during the driving of the vehicle, these forces will be transmitted to the buffer assembly 3 through the support base 2. The elastic plate 303 in the buffer assembly 3 will elastically deform again to absorb and disperse these impact forces, thereby protecting the battery module from damage.

[0055] Recovery and repetition: During continuous up and down bumps, the buffer assembly 3 continuously undergoes a process of deformation and recovery, effectively reducing the vibration and impact of the battery module and protecting it from damage.

[0056] The buffer assembly 3 effectively absorbs and disperses the impact force of the battery module when it bumps through the rotation of the rotating disk 301, the deformation of the elastic plate 303 and the buffering effect of the guide wall 3021. This not only improves the durability of the battery compartment, but also ensures the safety and stability of the battery module during placement.

[0057] In addition, the end of the elastic plate 303 away from the rotating disk 301 is rotatably connected to a roller 305, and the roller 305 is rollingly connected to the guide wall 3021. Since the roller 305 can roll more smoothly on the guide wall 3021, the response speed of the elastic plate 303 will be faster and the movement efficiency will be higher. This helps to ensure that the battery compartment can be quickly and effectively buffered when it is impacted or bumped. The use of the roller 305 reduces the direct contact between the elastic plate 303 and the guide wall 3021, thereby extending the service life of these components. In addition, the roller 305 is usually made of wear-resistant material, which can further increase its durability.

[0058] Embodiment 2

[0059] like Figure 6 As shown, on the basis of the first embodiment, in order to more effectively absorb and disperse the impact energy and provide a better buffering effect, a clamping wall 3022 is provided on the side wall of the guide frame 302 corresponding to each guide wall 3021, and the outer arc surface of the elastic plate 303 is movably pressed against the clamping wall 3022.

[0060] like Figure 6 As shown, when the rotating disk 301 rotates to cause the end of the elastic plate 303 to slide on the guide wall 3021, the elastic plate 303 is deformed, and the outer arc surface of the elastic plate 303 moves toward the abutting wall 3022. When the deformation of the elastic plate 303 is too large, a point of the outer arc surface of the elastic plate 303 will abut against the abutting wall 3022.

[0061] Working principle:

[0062] When the rotating disk 301 rotates, it drives the end of the elastic plate 303 to slide on the guide wall 3021. During this process, the elastic plate 303 will deform according to the magnitude of the force received.

[0063] In the case of slight bumps, the deformation of the elastic plate 303 is moderate, which can effectively absorb and disperse the impact energy and protect the battery module in the battery compartment from damage.

[0064] However, when encountering a large bump or impact, the deformation of the elastic plate 303 may become too large. At this time, a point on the outer arc surface of the elastic plate 303 will be pressed against the pressing wall 3022. This contact not only limits the further deformation of the elastic plate 303, but also enhances the elastic strength of the elastic plate 303 by adding additional support points. When the battery compartment is subjected to a large bump or impact, the interaction between the elastic plate 303 and the pressing wall 3022 can more effectively absorb and disperse the impact energy, thereby providing a better buffering effect.

[0065] Embodiment 3

[0066] like Figure 3 , Figure 7 and Figure 8 As shown, on the basis of embodiment 1, in order to facilitate the installation of the support seat 2 in the housing 1, the buffer assembly 3 also includes a mounting plate 306, and the mounting plate 306 is rotatably connected to the connecting shaft 3042, and a bearing is arranged between the connecting shaft 3042 and the mounting plate 306, and a groove 201 is opened on the side wall of the support seat 2, and the mounting plate 306 is fixed inside the groove 201 by bolts.

[0067] The two connecting shafts 3042 on the same side of the same support seat 2 jointly support a mounting plate 306, so that after the mounting plate 306 is installed on the connecting shaft 3042, the mounting plate 306 is in a vertical state. After the mounting plate 306 is installed on the connecting shaft 3042, the support seat 2 is installed into the outer shell 1. At this time, the mounting plate 306 is in the sink groove 201, and then the support seat 2 and the mounting plate 306 are fixed with bolts to achieve the installation of the support seat 2.

[0068] In addition, if Figure 8 As shown, if the battery module is placed on the support base 2, the extension rod 3041 is deflected downward by a certain angle by utilizing the gravity of the battery module, so that the support base 2 moves downward. At this time, the mounting plate 306 will move as shown in FIG. Figure 8 The two support seats 2 slide relative to each other in the direction of the arrows shown. At this time, the two support seats 2 also have a corresponding clamping effect on the battery module, thereby increasing the stability of the battery module.

[0069] Embodiment 4

[0070] like Figure 3 As shown, based on the above embodiment, in this embodiment, a plurality of buffer strips 4 are arranged on the support seat 2, and the plurality of buffer strips 4 are distributed at intervals, and the material of the buffer strips 4 is rubber material; the buffer strips 4 can effectively reduce the impact and vibration of the battery module during operation, thereby extending the service life and performance stability of the battery. By arranging the buffer strips 4 at the bottom of the battery module, a certain gap can be formed, and these gaps can be used as ventilation channels to help the battery module dissipate heat.

[0071] Finally, it should be noted that the above embodiments are only used to illustrate rather than limit the technical solutions of the present invention. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that the present invention can still be modified or replaced by equivalents. Any modification or partial replacement that does not depart from the spirit and scope of the present invention should be included in the scope of the claims of the present invention.
