Description

Technical Field

[0001] This utility model relates to the field of new energy power battery transfer equipment technology, specifically to a protective device for new energy vehicle power batteries. Background Technology

[0002] Graphene batteries are a new type of battery technology based on graphene materials. Their core advantage lies in using the unique physicochemical properties of graphene (such as high conductivity, lightweight, and high strength) to improve battery performance. In particular, graphene batteries can achieve rapid charging and discharging through the efficient shuttle movement of lithium ions between the graphene surface and the electrodes, making them highly valuable for applications in the field of new energy power batteries.

[0003] One of the aforementioned forms of power batteries for new energy vehicles is the cylindrical battery. Currently, the conventional method for transporting these batteries after production involves using components such as sponges as transport tools. Specifically, mounting holes for the cylindrical batteries are cut into the top of the sponge, and the batteries are inserted into these holes during transport. However, since the internal solution of the graphene battery may leak during transport, this leakage not only contaminates the transport tools but also poses a significant safety hazard. Therefore, it is necessary to install a dedicated transport device for power batteries to ensure safety during transport. Utility Model Content

[0004] The present invention aims to provide a protective device for power batteries of new energy vehicles, so as to solve the problems of poor stability and safety risks of power batteries of new energy vehicles during transportation in the prior art.

[0005] To solve the above problems, the present invention adopts the following technical solution: a protective device for a power battery of a new energy vehicle, including a transfer box and rollers rotatably connected to the bottom of the transfer box. A rotating door is rotatably connected to the front side of the transfer box. An installation plate is slidably connected laterally inside the transfer box. The top surface of the installation plate has multiple arrayed installation holes. A cover plate is slidably connected vertically inside the transfer box. An elastic support is connected between the cover plate and the transfer box. A linkage mechanism is connected between the cover plate and the installation plate. When the installation plate slides into the transfer box, the linkage mechanism drives the cover plate to slide to cover the top of the installation plate.

[0006] The principles and beneficial effects of this application are as follows: This application includes a storage space inside the transport box for storing power batteries. A rotating door is rotatably connected to the front of the transport box. When the power battery is placed inside the transport box, the rotating door can be rotated to close. At this time, the transport box can be pushed to rotate the rollers at the bottom of the transport box, thereby conveniently pushing the power battery inside the transport box to other places.

[0007] When installing the power battery into the transfer box using existing technology, first turn the rotating door to open it, then pull the mounting plate outward. The mounting plate slides outward relative to the transfer box, so that the mounting hole on the top surface of the mounting plate slides outside the transfer box. Under the elastic force of the elastic support, the cover slides upward relative to the transfer box, so that the cover moves away from the top surface of the mounting plate, ensuring that the mounting hole on the top surface of the mounting plate is not obstructed by the cover. At this point, the power battery can be placed into the mounting hole. After the power battery is installed, slide the mounting plate into the transfer box. When the mounting plate slides into the transfer box, under the driving action of the linkage mechanism, the cover slides to the state of closing the top of the mounting plate. The cover is used to secure and protect the power battery installed in the mounting hole.

[0008] In summary, this application utilizes a transfer box to transport the power battery, making the transport more convenient and stable. Furthermore, a movable cover is installed inside the transfer box. When the mounting plate with the power battery installed is slid into the transfer box, a linkage mechanism automatically drives the cover to slide downwards and close the top of the mounting plate. This not only secures the power battery but also, with the mounting plate and cover positioned below and above the power battery respectively, protects it during transport, thus improving the stability and safety of the power battery during transport.

[0009] Preferably, as an improvement, the linkage mechanism includes a push-pull block and a drive column fixedly connected to the push-pull block, the push-pull block being fixedly connected to the top of the mounting plate; the side of the cover plate is provided with a drive groove that slides with the drive column; the drive groove includes a transverse bottom section, a transverse top section, and an inclined section that is inclinedly connected between the transverse bottom section and the transverse top section.

[0010] In this design, the push-pull block is fixedly connected to the top of the mounting plate and located outside the side of the cover plate. A drive column is fixed on the push-pull block. When the push-pull block slides into the transfer box along with the mounting plate, the push-pull block can drive the drive column closer to the cover plate. The drive column slides into the drive groove. Since the drive groove consists of a horizontal bottom section, an inclined section, and a horizontal top section, the height of the horizontal bottom section is lower than that of the horizontal top section, and the horizontal bottom section is located near the end of the cover plate facing outward from the transfer box. When the drive column slides into the drive groove, the drive column first contacts the horizontal bottom section, and then slides into contact with the inclined section, causing the cover plate to slide closer to the mounting plate. When the drive column slides to the horizontal top section, the cover plate and the top of the mounting plate are closed, thus securing the power battery to the mounting hole.

[0011] Preferably, as an improvement, a rotating sleeve is rotatably connected to the outer side of the drive column.

[0012] In this design, a rotating sleeve is rotatably connected to the outside of the drive column. When the drive column slides with the drive groove, the rotating sleeve rolls with the drive groove. This not only reduces the pushing force on the mounting plate, making manual installation and transfer of the power battery easier, but also effectively reduces wear on the drive groove, which is beneficial for improving the long-term stable operation of the device.

[0013] Preferably, as an improvement, an insulating elastic plate is fixedly connected to the bottom surface of the cover plate.

[0014] In this design, an elastic insulating plate is fixedly connected to the bottom surface of the cover plate. When the cover plate is close to the bottom of the mounting plate, it can contact and press against the power battery, while providing elastic protection for the power battery.

[0015] Preferably, as an improvement, the transverse top section is inclined, and the high end of the transverse top section is connected to the inclined section, and the inclination angle of the transverse top section is 1 to 3°.

[0016] In this design, the top horizontal section is tilted, and the high end of the top horizontal section is connected to the tilted section. When the rotating sleeve rotates into the top horizontal section, the tilted design prevents the rotating sleeve from easily exiting the top horizontal section. This allows the cover plate and the insulating elastic plate to more stably hold and fix the power battery in place. The tilt angle of the top horizontal section is set to 1 to 3 degrees to avoid the situation where the tilt angle is too large and it is difficult for a person to easily pull the rotating sleeve out of the top horizontal section.

[0017] Preferably, as an improvement, the transverse top section is located at the middle position in the length direction of the cover plate.

[0018] In this design, the horizontal top section is positioned at the middle of the cover plate's length. When the mounting plate is pushed into the transfer box, the rotating sleeve acts on the middle of the cover plate's length, allowing the cover plate to slide downwards more smoothly and press against the power battery on the mounting plate.

[0019] Preferably, as an improvement, the number of linkage mechanisms is two, and the two linkage mechanisms are located on both sides of the cover plate.

[0020] In this design, linkage mechanisms are installed on both sides of the cover plate to make the force on the cover plate more even, so that the cover plate can slide down more smoothly to the top of the mounting plate and can maintain the state of the mounting plate more stably after closing, thus making the power battery more stably installed in the mounting hole during transportation.

[0021] Preferably, as an improvement, a guide post is fixedly connected inside the transfer box, a limiting plate is fixedly connected to the bottom end of the guide post, a sliding hole is opened on the cover plate to slide with the guide post, and a limiting hole is opened on the bottom surface of the cover plate to cooperate with the limiting plate.

[0022] In this design, the movable groove and guide post provide limits and guidance for the vertical movement of the cover plate, enabling the cover plate to slide vertically more smoothly, steadily, and precisely. At the same time, the limiting plate can prevent the cover plate from falling downwards.

[0023] Preferably, as an improvement, the number of guide posts is four, and the four guide posts are located at the four corners of the cover plate. The elastic support includes a support spring sleeved on the guide posts.

[0024] In this design, the support springs are sleeved on the guide posts, with the bottom end of the support spring abutting against the top end of the limiting plate and the top end of the support spring abutting against the bottom surface of the cover plate. The four support springs are located at the four corners of the cover plate, and under the elastic force of the support springs, they can provide stable elastic support for the cover plate.

[0025] Preferably, as an improvement, a handle is fixedly connected to the front side of the mounting plate.

[0026] In this design, the installation plate can be pushed and pulled manually using handles, making operation more convenient. Attached Figure Description

[0035] The following detailed description illustrates the specific implementation method: The reference numerals in the accompanying drawings include: transfer box 1, mounting cavity 101, roller 2, rotating door 3, mounting plate 4, mounting hole 401, T-shaped plate 5, cover plate 6, guide post 7, limit plate 8, support spring 9, insulating elastic plate 10, push-pull block 11, drive post 12, drive groove 13, transverse bottom section 1301, transverse top section 1302, inclined section 1303, and rotating sleeve 14.

[0036] Example 1 This embodiment is as shown in the attached figure. Figure 1 As shown: A protective device for a power battery of a new energy vehicle includes a transfer box 1. The transfer box 1 is hollow inside to form a placement space. Rollers 2 are rotatably connected to the four corners of the bottom of the transfer box 1, which can push the transfer box 1 to move. A rotating door 3 is rotatably connected to the front of the transfer box 1 via a hinge. After the rotating door 3 is rotated open, a graphene battery of the prior art can be placed into the transfer box 1.

[0037] Combination Figure 1 and Figure 2 The transfer box 1 has multiple mounting plates 4 that slide horizontally inside. These mounting plates 4 are arranged at equal intervals along the vertical direction. To facilitate the installation and connection of these mounting plates 4, in this example, the internal space of the transfer box 1 is divided into multiple mounting cavities 101, with only one mounting plate 4 installed in each cavity 101. Combined with... Figure 4 The top surface of the mounting plate 4 has multiple arrayed mounting holes 401. In this embodiment, the mounting holes 401 are arranged in a rectangular row to mount a cylindrical power battery (i.e., the aforementioned graphene battery) from the prior art. To facilitate stable and smooth sliding between the mounting plate 4 and the transfer box 1, T-slots are provided on both sides of the mounting plate 4. T-plates 5 that slide in conjunction with the T-slots are fixedly connected to the left and right walls inside the transfer box 1 by screws. In use, the T-slots of the mounting plate 4 are inserted into the T-plates 5, allowing the mounting plate 4 to be pushed and pulled. Furthermore, to facilitate manual pushing and pulling of the mounting plate 4, a handle is fixedly connected to the front side of the mounting plate 4 by screws. Figure 2 (not shown in the image); At the same time, in order to prevent the mounting plate 4 from slipping off the T-shaped plate 5, after the mounting plate 4 is installed, a limiting block can be fixed to the end of the T-shaped plate 5 near the front of the transfer box 1 with screws. The limiting block can be used to limit the sliding of the mounting plate 4 and provide protection.

[0038] Combination Figure 2 and Figure 3A cover plate 6 is vertically slidably connected inside the transfer box 1. The number of cover plates 6 is equal to the number of mounting plates 4 and they are set one-to-one. The cover plate 6 is located above the mounting plate 4, and an elastic support is connected between the cover plate 6 and the transfer box 1. When the cover plate 6 is not subjected to other external forces, it is in a state away from the mounting plate 4 under the support of the elastic support. In addition, in this embodiment, a linkage mechanism is connected between the cover plate 6 and the mounting plate 4. When the mounting plate 4 slides completely into the transfer box 1, the linkage mechanism drives the cover plate 6 to slide down to cover the top of the mounting plate 4, so that the mounting plate 4 and the cover plate 6 respectively support and fix the bottom and top of the graphene battery, preventing the graphene battery from loosening from the mounting hole 401 during the transfer process, and ensuring the stability and safety of the graphene battery during the transfer process.

[0039] To ensure that the cover plate 6 can slide smoothly and vertically relative to the transfer box 1, in this embodiment, four guide posts 7 are fixedly connected to the top wall of the mounting cavity 101 by screws. These four guide posts 7 are located at the four corners of the cover plate 6. Figure 5 The cover plate 6 has a sliding hole that slides with the guide post 7. The bottom end of the guide post 7 is fixedly connected to a limiting plate 8 with a diameter larger than the guide post 7 by screws. The bottom surface of the cover plate 6 has a limiting hole that mates with the limiting plate 8. The depth of the limiting hole is greater than or equal to the thickness of the limiting plate 8 to prevent the bottom surface of the limiting plate 8 from protruding beyond the bottom surface of the cover plate 6 and contacting the top surface of the mounting plate 4, thus preventing the top surface of the cover plate 6 from not covering the top surface of the mounting plate 4. At the same time, the elastic support in this embodiment includes a support spring 9 sleeved on the guide post 7. The bottom end of the support spring 9 abuts against the top surface of the limiting plate 8, and the top end of the support spring 9 abuts against the cover plate 6. In addition, in order to ensure that the cover plate 6 can stably and securely hold the graphene battery installed in the mounting hole 401 and to prevent the graphene battery from being squeezed and damaged, an insulating elastic plate 10, such as an elastic plate made of rubber, is fixedly connected to the bottom surface of the cover plate 6 by screws.

[0040] Combination Figure 2 , Figure 3 and Figure 6As shown, there are two linkage mechanisms, and the two linkage mechanisms are located on the left and right sides of the cover plate 6. The linkage mechanism in this embodiment includes a push-pull block 11 and a drive column 12 fixedly connected to the side of the push-pull block 11 by screws. The push-pull block 11 is fixedly connected to the top of the mounting plate 4 near the side by screws. The left and right walls of the cover plate 6 are provided with drive grooves 13 that slide with the drive column 12. The drive groove 13 includes a horizontal bottom section 1301, a horizontal top section 1302 and an inclined section 1303. The horizontal bottom section 1301 is near the end of the cover plate 6 near the front side of the transfer box 1. The horizontal bottom section 1301 and the horizontal top section 1302 are both horizontally arranged. The height of the horizontal top section 1302 is higher than that of the horizontal bottom section 1301. The inclined section 1303 is inclinedly connected between the horizontal top section 1302 and the horizontal bottom section 1301. In order to enable the drive column 12 to slide smoothly into the horizontal bottom section 1301, a guide notch is provided at the end of the horizontal bottom section 1301 facing the front side of the transfer box 1.

[0041] The specific implementation process is as follows: When the graphene battery is processed and needs to be transferred, first turn to open the rotating door 3, then pull the mounting plate 4 outside the transfer box 1 using the handle, and insert the graphene battery into the mounting hole 401. After all the mounting holes 401 on the mounting plate 4 have been filled with graphene batteries, manually push the mounting plate 4 into the transfer box 1. As the mounting plate 4 slides into the transfer box 1, it drives the push-pull block 11 and the drive column 12 to slide. When the drive column 12 slides, it first enters the horizontal bottom section 1301, and then slides into the inclined section 1303. Under the driving force of the drive column 12, the cover plate 6 slides downward. When the horizontal top section 1302 is reached, the insulating elastic plate 10 at the bottom of the cover plate 6 abuts against the top of the graphene battery. To prevent the insulating elastic plate 10 from continuing to slide laterally after it abuts against the top of the graphene battery, resulting in relative friction between the insulating elastic plate 10 and the top of the graphene battery, the length of the horizontal top section 1302 can be controlled in this embodiment. The length of the horizontal top section 1302 is equal to or slightly larger than the diameter of the drive column 12 (for example, the length of the horizontal top section 1302 is 1-2 mm larger than the diameter of the drive column 12), so that the insulating elastic plate 10 can stably abut and fix the graphene battery to the mounting plate 4.

[0042] In this embodiment, graphene batteries can be installed on all mounting plates 4 one after another. Then, the rotating door 3 is rotated and closed. The rotating door 3 can be locked and fixed to the transfer box 1 using the existing locking structure. At this time, all graphene batteries are stably fixed in the transfer box 1, and the top and bottom of the graphene batteries are fixed by the cover plate 6 and the mounting plate 4 respectively, ensuring that the graphene batteries can be stably fixed and protected during the transfer process. The graphene batteries fixed on the upper and lower adjacent mounting plates 4 are isolated from each other to avoid mutual interference between the graphene batteries, further improving the stability and safety of the graphene batteries during the transfer process.

[0043] Example 2 The difference between Example 2 and Example 1 is as follows: Figure 7 As shown, in this embodiment, a rotating sleeve 14 is rotatably connected to the outside of the drive column 12. When the mounting plate 4 is pushed into the transfer box 1 and the drive column 12 enters the drive groove 13, the rotating sleeve 14 and the drive groove 13 roll together, effectively reducing the thrust when the mounting plate 4 slides relative to the cover plate 6, making it easier for the operator to push the mounting plate 4 to slide. At the same time, it reduces the wear of the drive groove 13, so that the drive groove 13 can still accurately drive the cover plate 6 to slide even after long-term use.

[0044] Example 3 The difference between Example 3 and Example 1 is as follows: Figure 8 As shown, in this embodiment, the horizontal top section 1302 is also inclined, and the high end of the horizontal top section 1302 is connected to the high end of the inclined section 1303. The inclination angle θ of the horizontal top section 1302 is 1 to 3°, preferably 2° or 3°. In this embodiment, by inclining the horizontal top section 1302, when the drive column 12 slides to the horizontal top section 1302, it will not easily slide towards the inclined section 1303. This helps the drive column 12 to remain in the horizontal top section 1302, allowing the cover plate 6 and the insulating elastic plate 10 to more stably hold and fix the graphene battery.
