Description

Technical Field

[0001] This application relates to the technical field of electric vehicles, and in particular to a battery support device that facilitates the placement and removal of batteries. Background Technology

[0002] Currently, with the continuous development and advancement of electric vehicles, the requirements for their power battery systems are becoming increasingly stringent. However, due to limitations in battery materials, the charging efficiency of power battery packs remains relatively low, making it impossible to complete rapid charging in a short time to guarantee vehicle range. Therefore, fast battery swapping devices are currently an effective way to address range anxiety.

[0003] In existing technologies, the installation and removal of power battery packs typically require the use of a hydraulic lift due to their weight. When installing the power battery pack, the hydraulic lift first raises it, then multiple bolts are used to secure it to the vehicle chassis. When removing the power battery pack, the hydraulic lift first supports it, then the bolts connecting the battery pack to the chassis are removed. Finally, the hydraulic lift lowers the battery pack, allowing for its removal.

[0004] However, in the existing technology, the power battery pack is connected to the car chassis by multiple bolts, which makes it labor-intensive for operators to disassemble and assemble the power battery pack, thus making it inconvenient to disassemble and assemble the power battery pack. Summary of the Invention

[0005] To facilitate the installation and removal of power battery packs, this application provides a support device for easy battery placement and removal, employing the following technical solution: A battery support device for easy battery placement and removal includes a vehicle chassis and a power battery pack. The bottom of the vehicle chassis has a receiving groove for accommodating the power battery pack. A connecting plate is connected to the bottom of the power battery pack. Electrode mounting plates are respectively installed on both sides of the power battery pack, with a positive terminal and a negative terminal mounted on each plate. The top wall of the receiving groove has a positive terminal hole and a negative terminal hole. The positive terminal is inserted into the positive terminal hole, and the negative terminal is inserted into the negative terminal hole. A quick-release mechanism for securing the power battery pack is installed within the receiving groove. The quick-release mechanism includes two vertical slots respectively opened on both sides of the receiving groove, and two vertical slots respectively opened on the two vertical slots. The groove has two first through holes on opposite inner sides and two first support racks slidably connected to the two first through holes respectively; the two first support racks abut against the bottom of the two electrode mounting plates respectively; a vertical tube is rotatably connected in each vertical groove; a gear is fixedly sleeved on the outer wall of the vertical tube; the gear meshes with the first support rack; a first horizontal groove is opened on one side of the first through hole; a first slider is slidably connected in the first horizontal groove; a first spring is fixedly connected to one side of the first slider; the end of the first spring away from the first slider is fixedly connected to the inner wall of one end of the first horizontal groove; the first slider is fixedly connected to one side of the first support rack; a drive assembly for driving the two vertical tubes to rotate is installed in the receiving groove.

[0006] By adopting the above technical solution, when the power battery pack needs to be installed, the hydraulic lift first drives the power battery pack to move into the receiving slot until the positive terminal is inserted into the positive terminal hole and the negative terminal is inserted into the negative terminal hole. Then, the drive assembly drives the two vertical tubes to rotate, which in turn drives the two gears to rotate. The two gears then drive the two first support racks to move towards the two electrode mounting plates, thus supporting the two electrode mounting plates. At this point, the power battery pack can be installed under the limiting action of the positive terminal and the positive terminal hole, and the negative terminal and the negative terminal hole. When the power battery pack needs to be disassembled, the hydraulic lift is first started to make the worktable of the hydraulic lift contact the power battery pack. Then, the drive assembly drives the two vertical tubes to rotate in opposite directions, which in turn drives the two gears to rotate in opposite directions. The two gears then drive the two first support racks to move away from the two electrode mounting plates, thus allowing the power battery pack to be disassembled. In summary, the quick-release mechanism facilitates the installation and disassembly of the power battery pack.

[0007] Optionally, the drive assembly includes an electric push rod installed in the receiving groove, a clearance groove formed on the top wall of the receiving groove, and a drive plate slidably connected to the inner wall of the clearance groove; the piston rod of the electric push rod is fixed to the bottom of the drive plate; second horizontal grooves are respectively formed on both sides of the clearance groove, and the two second horizontal grooves are respectively connected to two vertical grooves; a push plate is slidably connected in each second horizontal groove, and a reset component for resetting the push plate is installed in the second horizontal groove; each push plate has an inclined surface on its opposite inner side to the drive plate, and the two inclined surfaces... The vertical groove is fitted with a movable plate that slides within it. The movable plate has a spherical surface at its end near the push plate, which matches the end of the push plate away from the drive plate. A movable rod is fixedly connected to the bottom of the movable plate. Multiple spiral blocks are sequentially fixed to the sidewall of the movable rod along its circumference. Multiple spiral grooves are sequentially opened on the inner wall of the vertical tube along its circumference, and the spiral blocks match the spiral grooves. A second spring is fixedly connected to the end of the movable rod away from the movable plate, and the end of the second spring away from the movable rod is fixedly connected to the bottom of the vertical groove.

[0008] By adopting the above technical solution, when it is necessary to drive the two vertical tubes to rotate, the electric push rod is first activated. The piston rod of the electric push rod drives the drive plate downwards. Then, under the action of the inclined plane, the drive plate drives the two push plates to move closer to the moving plate. Subsequently, under the action of the spherical surface, the two push plates drive the two moving plates downwards. The downward movement of the two moving plates drives the two moving rods downwards. Next, under the action of the helical block and the helical groove, the two moving rods can drive the two vertical tubes to rotate. Furthermore, when the two push plates move closer to the moving plate, under the action of the two sets of reset components, the two push plates tend to move away from the moving plate. When the two moving rods move downwards, the two second springs are in a compressed state. When it is necessary to drive the two vertical tubes to rotate in the opposite direction, the electric push rod is first activated. The piston rod of the electric push rod drives the drive plate upwards. Then, the two push plates are reset under the action of the two sets of reset components. Next, the two moving rods are reset under the action of the two second springs. Finally, under the action of the helical block and the helical groove, the two moving rods can drive the two vertical tubes to rotate in the opposite direction. In summary, the designed drive assembly facilitates the rotation of the two vertical tubes.

[0010] By adopting the above technical solution, when the push plate moves towards the moving plate, it drives the reset block to move, and the movement of the reset block presses against the reset spring; when the drive plate is reset, the reset block drives the push plate to reset under the action of the reset spring; in summary, the reset component facilitates the reset of the push plate.

[0011] Optionally, guide plates are fixed to both ends of the connecting plate, and two guide grooves are provided at the bottom of the vehicle chassis, with the two guide plates respectively inserted into the two guide grooves.

[0016] By adopting the above technical solution, when the power battery pack needs to be installed, the electric push rod is first activated. At this time, the piston rod of the electric push rod drives the drive plate to move downward. Then, under the action of the inclined plane, the drive plate drives the push plate to move closer to the moving plate. Subsequently, under the action of the spherical surface, the push plate drives the moving plate to move downward. The downward movement of the moving plate drives the moving rod to move downward. Next, under the action of the spiral block and the spiral groove, the moving rod drives the vertical tube to rotate. The rotation of the vertical tube drives the second support rack to move closer to the slot. This allows the second support rack to be inserted into the slot, thereby supporting the guide plate. In summary, the set support mechanism facilitates the support of the guide plate.

[0017] Optionally, a reminder mechanism is installed in the mounting slot.

[0018] By adopting the above technical solution, the set reminder mechanism facilitates the observation of whether the first support rack and the second support rack have moved into place.

[0020] By adopting the above technical solution, when the second support rack is inserted into the slot, the second support rack drives the vertical block to move. Then, the drive assembly drives the rotating plate to rotate under the action of the vertical block. The rotation of the rotating plate drives the connecting rod to move. The movement of the connecting rod drives the reminder block to move downward along the third through hole. When the reminder block moves to align the through hole with the threaded hole, the connecting screw is installed. In this way, the operator can know whether the first support rack and the second support rack have moved into place. In summary, the reminder mechanism facilitates the observation of whether the first support rack and the second support rack have moved into place.

When installing the power battery pack, the hydraulic lift first moves the battery pack into the receiving slot until the positive terminal is inserted into the positive terminal hole and the negative terminal is inserted into the negative terminal hole. Then, the drive assembly drives the two vertical tubes to rotate, which in turn drives the two gears to rotate. The gears then drive the two first support racks to move towards the two electrode mounting plates, thus supporting the two electrode mounting plates. At this point, the power battery pack can be installed under the limiting action of the positive terminal and the positive terminal hole, and the negative terminal and the negative terminal hole. When disassembling the power battery pack, the hydraulic lift is first started to bring the worktable of the hydraulic lift into contact with the power battery pack.

[0034] This application discloses a battery support device for easy battery placement and removal, referring to... Figures 1-3 The system includes a vehicle chassis 1 and a power battery pack 2. The bottom of the vehicle chassis 1 has a receiving groove 11 for accommodating the power battery pack 2. A connecting plate 21 is connected to the bottom of the power battery pack 2. Electrode mounting plates 22 are installed on both sides of the power battery pack 2. Positive terminal 23 and negative terminal 24 are installed on the two electrode mounting plates 22 respectively. The top wall of the receiving groove 11 has a positive terminal hole 12 and a negative terminal hole 13.

When the power battery pack 2 needs to be installed, it is first moved into the receiving slot 11 by a hydraulic lift until the positive terminal 23 is inserted into the positive terminal hole 12 and the negative terminal 24 is inserted into the negative terminal hole 13. Then, the two vertical tubes 33 are driven to rotate by the drive assembly 4. The rotation of the two vertical tubes 33 drives the two gears 34 to rotate. The rotation of the two gears 34 drives the two first support racks 32 to move towards the two electrode mounting plates 22, thus supporting the two electrode mounting plates 22. At this time, the positive terminal 23 is connected to the positive terminal hole 12 and the negative terminal 24. The power battery pack 2 can be installed under the limiting action of the negative terminal connection hole 13. When it is necessary to disassemble the power battery pack 2, first start the hydraulic lift to make the work platform of the hydraulic lift contact the power battery pack 2, and then drive the two vertical tubes 33 to rotate in opposite directions through the drive component 4. The two vertical tubes 33 rotate in opposite directions, which drives the two gears 34 to rotate in opposite directions. The two gears 34 rotate in opposite directions, which drives the two first support racks 32 to move away from the two electrode mounting plates 22, thereby disassembling the power battery pack 2. In summary, the quick-release mechanism 3 facilitates the disassembly and assembly of the power battery pack 2.

Then, under the action of the inclined surface 441, the drive plate 43 drives the two push plates 44 to move closer to the moving plate 45. Subsequently, under the action of the spherical surface 451, the two push plates 44 drive the two moving plates 45 to move downward. The downward movement of the two moving plates 45 drives the two moving rods 46 to move downward. Next, under the action of the spiral block 461 and the spiral groove 331, the two moving rods 46 can drive the two vertical tubes 33 to rotate. In addition, when the two push plates 44 move closer to the moving plate 45, under the action of the two sets of reset members 48, the two push plates 44 have a tendency to move away from the moving plate 45. When the two moving rods 46 move downward, the two second springs 47 are in a compressed state. When it is necessary to drive the two vertical tubes 33 to rotate in opposite directions, the electric push rod 41 is activated first.

When the push plate 44 moves toward the moving plate 45, it drives the reset block 482 to move, and the movement of the reset block 482 presses against the reset spring 483. When the drive plate 43 is reset, the reset block 482 drives the push plate 44 to reset under the action of the reset spring 483. In summary, the reset component 48 facilitates the reset of the push plate 44.

Two guide grooves 14 are vertically formed at the bottom of the vehicle chassis 1, and the two guide plates 25 are respectively inserted into the two guide grooves 14. The guide plates 25 and guide grooves 14 facilitate the installation of the power battery pack 2.

A third spring 55 is horizontally fixed to one side of the vertical block 54. The end of the third spring 55 away from the vertical block 54 is fixed to the inner wall of the mounting groove 313. When the power battery pack 2 needs to be installed, the electric push rod 41 is activated first. At this time, the piston rod of the electric push rod 41 drives the drive plate 43 to move downward. Then, under the action of the inclined surface 441, the drive plate 43 drives the push plate 44 to move closer to the moving plate 45. Subsequently, under the action of the spherical surface 451, the push plate 44 drives the moving plate 45 to move downward. The downward movement of the moving plate 45 drives the moving rod 46 to move downward. Next, under the action of the spiral block 461 and the spiral groove 331, the moving rod 46 drives the vertical tube 33 to rotate. The rotation of the vertical tube 33 drives the second support rack 52 to move closer to the slot 53. This allows the second support rack 52 to be inserted into the slot 53, thereby supporting the guide plate 25. In summary, the support mechanism 5 is designed to facilitate the support of the guide plate 25.

The reminder mechanism 6 also includes a drive assembly 7 installed on the inner wall of the mounting groove 313 for driving the rotating plate 64 to rotate. The drive assembly 7 is correspondingly arranged with the vertical block 54. When the second support rack 52 is inserted into the slot 53, the second support rack 52 drives the vertical block 54 to move. Then, the drive assembly 7 drives the rotating plate 64 to rotate under the action of the vertical block 54. The rotation of the rotating plate 64 drives the connecting rod 66 to move. The movement of the connecting rod 66 drives the reminder block 62 to move downward along the third through hole 61. When the reminder block 62 moves to align the through hole 621 with the threaded hole 251, the connecting screw 67 is installed. In this way, the operator can know whether the first support rack 32 and the second support rack 52 have moved into place. In summary, the reminder mechanism 6 is designed to facilitate the observation of whether the first support rack 32 and the second support rack 52 have moved into place.

One end of the drive plate 74 abuts against the side of the vertical block 54 away from the gear 34, and the bottom of the other end is vertically fixed to a push block 77, which abuts against one side of the rotating plate 64. When the second support rack 52 is inserted into the slot 53, the second support rack 52 drives the vertical block 54 to move. The movement of the vertical block 54 drives the drive plate 74 to move. The movement of the drive plate 74 drives the push block 77 to move. The movement of the push block 77 can drive the rotating plate 64 to rotate. In summary, the drive assembly 7 is provided to facilitate the rotation of the rotating plate 64.

[0043] Reference Figure 1 and Figure 5The bottom of the electric push rod 41 is equipped with a buffer mechanism 8 for cushioning the power battery pack 2. The buffer mechanism 8 includes a fixed plate 81 installed at the bottom of the electric push rod 41, multiple buffer grooves 82 formed at the bottom of the fixed plate 81, buffer rods 83 that slide vertically and are connected to the multiple buffer grooves 82, and buffer plates 84 fixed to the bottom of the multiple buffer rods 83. A buffer spring 85 is vertically fixed to the top of each buffer rod 83, and the end of the buffer spring 85 away from the buffer rod 83 is fixed to the top wall of the buffer groove 82. The bottom of the buffer plate 84 abuts against the top of the power battery pack 2. The buffer plate 84, buffer rods 83, and buffer springs 85 are provided to facilitate the cushioning of the power battery pack 2.

[0044] Working principle: When the power battery pack 2 needs to be installed, the power battery pack 2 is first moved into the receiving slot 11 by the hydraulic lift until the positive terminal 23 is inserted into the positive terminal hole 12 and the negative terminal 24 is inserted into the negative terminal hole 13. Then, the electric push rod 41 is activated. At this time, the piston rod of the electric push rod 41 drives the drive plate 43 to move downward. Next, the drive plate 43 drives the two push plates 44 to move towards the moving plate 45 under the action of the inclined surface 441. Then, the two push plates 44 drive the two moving plates 45 to move downward under the action of the spherical surface 451. The downward movement of the two moving plates 45 drives the two moving rods 46 to move downward. Next, the two moving rods 46 drive the two vertical tubes 33 to rotate under the action of the spiral block 461 and the spiral groove 331. The rotation of the two vertical tubes 33 drives the two gears 34 to rotate. The rotation of the two gears 34 drives the two first support racks 32 to move towards the two electrode mounting plates 22. This can support the two electrode mounting plates 22. With the support in place, the power battery pack 2 can be installed under the limiting action of the positive terminal 23 and the positive terminal hole 12, and the negative terminal 24 and the negative terminal hole 13. When it is necessary to disassemble the power battery pack 2, first start the hydraulic lift to make the work platform of the hydraulic lift contact the power battery pack 2, and then start the electric push rod 41. At this time, the piston rod of the electric push rod 41 drives the drive plate 43 to move upward. Then, the two push plates 44 are reset under the action of the two sets of reset parts 48. Next, the two moving rods 46 are reset under the action of the two second springs 47. Then, the two moving rods 46 drive the two vertical tubes 33 to rotate in the opposite direction under the action of the spiral block 461 and the spiral groove 331. The reverse rotation of the two vertical tubes 33 drives the two gears 34 to rotate in the opposite direction. The reverse rotation of the two gears 34 drives the two first support racks 32 to move away from the two electrode mounting plates 22, thereby disassembling the power battery pack 2. In summary, the quick-release mechanism 3 facilitates the disassembly and assembly of the power battery pack 2.
