Description

Technical Field

[0001] This utility model relates to the field of battery pack installation technology, specifically to a battery pack installation and positioning device for new energy vehicles. Background Technology

[0002] With the continuous development of the electric vehicle market and the technology of key new energy components, as well as their energy-saving and environmentally friendly characteristics, electric vehicles have entered people's daily lives. Especially in the logistics vehicle sector, pure electric logistics vehicles have become a hot topic in the market due to their energy saving, environmental protection, zero emissions, and low operating costs. Positioning devices are required to complete the installation of battery packs for electric vehicles.

[0003] Currently, battery packs in electric vehicles are typically fixed directly to the chassis frame using fasteners. This installation method makes disassembly and replacement of the battery pack inconvenient. While some battery packs use a pull-out structure to improve the efficiency of disassembly and installation, this pull-out structure allows the battery pack to move back and forth after installation. Especially when the car is driving on bumpy roads, the installed battery pack may move and cause power outages, affecting the normal use of the electric vehicle.

[0004] As disclosed in Chinese Patent CN215752022U, a quick-change positioning device for a new energy vehicle battery pack includes a vehicle body base plate, a mounting frame, and a pressing and positioning mechanism. Multiple battery packs are slidably connected within the mounting frame along the width of the vehicle body. Pressing and positioning mechanisms are provided on both sides of the vehicle body base plate at positions opposite to the battery packs. The pressing and positioning mechanisms elastically press and position the battery packs within the mounting frame.

[0005] When the above-mentioned device performs the positioning operation of the battery pack, it is necessary to place the battery pack stably, adjust the placement direction and angle of the battery pack, and then use a clamping mechanism to position and clamp the battery pack. This positioning method is inefficient, makes the installation of the battery pack more troublesome, and makes it inconvenient to adjust the position of the battery pack according to the installation height, thus affecting the installation efficiency.

[0006] To address this issue, a new energy vehicle battery pack installation and positioning device is proposed. Utility Model Content

[0007] The purpose of this utility model is to provide a new energy vehicle battery pack installation and positioning device to solve the problems mentioned in the background art.

[0008] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0009] A battery pack installation and positioning device for new energy vehicles includes a fixed base, support columns fixedly connected to the four corners of the upper surface of the fixed base, connecting seats fixedly connected to the upper surface of the support columns, a placement seat fixedly connected to the middle of the upper surface of the connecting seats, a base provided below the fixed base, a lifting component provided on the upper surface of the base, and a positioning component provided on the upper surface of the connecting seats.

[0010] Furthermore, the lifting assembly includes a moving module and a limiting module. The moving module includes a fixed plate fixedly installed on both sides of the upper surface of the base. A first drive motor is fixedly connected to one end of one side of the fixed plate, and a threaded column is rotatably installed on the other end of the fixed plate. One end of the threaded column is connected to the output end of the first drive motor. A moving block is engaged with the outer surface of the threaded column.

A second connecting shaft is installed on one end of the push plate. A connecting plate is fixedly connected to the upper part of the outer surface of the second connecting shaft. The upper part of the connecting plate is fixedly connected to the bottom surface of the fixed base.

[0011] Furthermore, the threaded column is provided with two reverse threads, the moving blocks are symmetrically distributed on the outer surfaces of both ends of the threaded column, and one end of each of the push plates on both sides is connected to the outer surface of the second connecting shaft.

[0012] Furthermore, the limiting module includes a mounting block fixedly connected to the outer surface of the base. A limiting post is fixedly connected to the middle position of the upper surface of the mounting block. A connecting block is installed on the outer surface of the fixed base, and a circular hole is passed through the middle position of the upper surface of the connecting block. The limiting post passes through the circular hole and is slidably connected to the connecting block.

[0013] Furthermore, the positioning component includes a rotation module and a stabilization module. The rotation module includes a second drive motor fixedly installed at the center of the bottom surface of the connecting seat. The output end of the second drive motor is connected to a transmission shaft. A gear is fixedly connected to the outer surface of the transmission shaft, and the bottom surface of the gear is rotatably connected to the upper surface of the placement seat. A concave seat is fixedly connected to the upper surface of the connecting seat. A rack is slidably connected to the inner wall of the concave seat. A horizontal column is fixedly installed on the upper surface of the connecting seat. A groove is formed on the upper surface of the horizontal column. A slider is slidably connected to the inner wall of the groove, and the upper surface of the slider is fixedly connected to the bottom surface of the rack.

[0014] Furthermore, the stabilizing module includes a connecting plate fixedly connected to one side of the upper surface of the rack. A placement platform is fixedly connected to one side of the upper surface of the connecting plate. A cylinder is fixedly connected to one end of the placement platform. A telescopic column is connected to the output end of the cylinder. A clamping plate is fixedly connected to one end of the telescopic column. A connecting rod is fixedly connected to the other end of the placement platform. A baffle is fixedly connected to the other end of the connecting rod.

[0015] The beneficial effects of this utility model are as follows:

[0016] This invention, by incorporating a lifting component, allows for easy adjustment of the battery pack's height after positioning and clamping, adapting to different vehicle installation heights. This improves installation efficiency and provides convenient and flexible operation. A connecting block is fixedly installed on the outer surface of the mounting base. As the mounting base moves, the connecting block slides on the outer surface of the limiting post, ensuring smooth movement of the mounting base. Two centrally symmetrically distributed racks move in opposite directions as the gear rotates, quickly positioning the battery pack. After positioning, an actuating cylinder pushes a telescopic column, which in turn moves the clamping plate, pushing the battery pack towards one side of the baffle for more stable positioning.

[0027] like Figure 1-4 As shown, a new energy vehicle battery pack installation and positioning device includes a fixed base 1, support columns 2 fixedly connected to the four corners of the upper surface of the fixed base 1, connecting seats 3 fixedly connected to the upper surface of the support columns 2, a placement seat 601 fixedly connected to the middle of the upper surface of the connecting seat 3, a base 4 provided below the fixed base 1, a lifting component 5 provided on the upper surface of the base 4, and a positioning component 6 provided on the upper surface of the connecting seat 3. After the battery pack is placed on the connecting seat 3, the positioning component 6 is operated to position and clamp the battery pack, and the lifting component 5 is operated to adjust the required installation height to improve installation efficiency.

[0028] The lifting assembly 5 includes a moving module and a limiting module. The moving module includes fixed plates 501 fixedly installed on both sides of the upper surface of the base 4. A first drive motor 502 is fixedly connected to one end of one fixed plate 501, and a threaded post 503 is rotatably installed on the other end of the fixed plate 501. One end of the threaded post 503 is connected to the output end of the first drive motor 502. A moving block 504 is engaged with the outer surface of the threaded post 503. A first connecting shaft 505 is fixedly connected to one end of the moving block 504. A push plate 506 is rotatably installed on the outer surface of the first connecting shaft 505. A certain feature is installed on one end of the push plate 506. The second connecting shaft 507 has a connecting plate 508 fixedly connected to the upper part of its outer surface. The upper surface of the connecting plate 508 is fixedly connected to the bottom surface of the fixed base 1. When the power of the first drive motor 502 is turned on, the output end of the first drive motor 502 drives the threaded column 503 to rotate, causing the moving blocks 504 meshing on the outer surfaces of both ends of the threaded column 503 to move towards each other, thereby driving the first connecting shaft 505 and the push plate 506 to move. The push plates 506 on both sides rotate on the outer surface of the first connecting shaft 505, raising the height of the second connecting shaft 507 and the connecting plate 508, thereby raising the height of the fixed base 1.

[0029] The threaded column 503 has two reverse threads. The moving blocks 504 are symmetrically distributed on the outer surfaces of both ends of the threaded column 503. One end of each of the push plates 506 on both sides is connected to the outer surface of the second connecting shaft 507. The threads on both sides of the outer surface of the threaded column 503 are symmetrically reversed, which makes it easier for the moving blocks 504 on both sides to move in opposite directions, and makes it more convenient to adjust the height of the fixed seat 1.

[0030] The limiting module includes a mounting block 509 fixedly connected to the outer surface of the base 4. A limiting post 510 is fixedly connected to the middle position of the upper surface of the mounting block 509. A connecting block 511 is installed on the outer surface of the fixed seat 1, and a circular hole 512 is passed through the middle position of the upper surface of the connecting block 511. The limiting post 510 passes through the circular hole 512 and is slidably connected to the connecting block 511. During the upward movement of the fixed seat 1, the connecting block 511 is moved and the connecting block 511 slides and is limited on the outer surface of the limiting post 510, so as to realize the smooth upward movement of the fixed seat 1.

[0031] The positioning component 6 includes a rotation module and a stabilizing module. The rotation module includes a second drive motor 602 fixedly installed at the center of the bottom surface of the connecting base 3. The output end of the second drive motor 602 is connected to a transmission shaft 603. A gear 604 is fixedly connected to the outer surface of the transmission shaft 603, and the bottom surface of the gear 604 is rotatably connected to the upper surface of the placement base 601. A concave seat 605 is fixedly connected to the upper surface of the connecting base 3. A rack 606 is slidably connected to the inner wall of the concave seat 605. A horizontal column 607 is fixedly installed on the upper surface of the connecting base 3. A groove 608 is formed on the upper surface of the horizontal column 607. A slider 609 is slidably connected to the inner wall of the groove 608. 9. The upper surface is fixedly connected to the bottom surface of the rack 606. When the new energy vehicle battery pack is placed on the upper surface of the placement platform 611 for positioning and stable clamping, the power of the second drive motor 602 is turned on. The output end of the second drive motor 602 drives the transmission shaft 603 to rotate, thereby driving the gear 604 fixedly installed on the outer surface of the transmission shaft 603 to rotate. Through meshing, when the gear 604 rotates, the racks 606, which are centrally symmetrically distributed, slide on the inner wall of the concave seat 605. The racks 606 on both sides move towards each other, respectively driving the placement platform 611 to move, so that the two sides of the outer surface of the battery pack contact the inner wall of the placement platform 611, thereby achieving positioning.

[0032] The stabilization module includes a connecting plate 610 fixedly connected to one side of the upper surface of the rack 606. A placement platform 611 is fixedly connected to one side of the upper surface of the connecting plate 610. A cylinder 612 is fixedly connected to one end of the placement platform 611. A telescopic column 613 is connected to the output end of the cylinder 612. A clamping plate 614 is fixedly connected to one end of the telescopic column 613. A connecting rod 615 is fixedly connected to the other end of the placement platform 611. A baffle 616 is fixedly connected to the other end of the connecting rod 615. The concave seat 605 and the rack 606 are centrally symmetrically distributed on both sides of the upper surface of the connecting seat 3. The rack 606 meshes with the gear 604. When the cylinder 612 is operated, the output end of the cylinder 612 pushes the telescopic column 613 to move. The telescopic column 613 drives the clamping plate 614 to move, pushing one side of the battery pack towards the baffle 616 to stabilize and clamp the battery pack, maintaining its stability during installation.

[0033] In summary, this new energy vehicle battery pack installation and positioning device places the new energy vehicle battery pack on the upper surface of the placement platform 611. When positioning and stabilizing the battery pack, the power to the second drive motor 602 is activated. The output end of the second drive motor 602 drives the transmission shaft 603 to rotate, thereby driving the gear 604 fixedly mounted on the outer surface of the transmission shaft 603 to rotate. Through meshing, as the gear 604 rotates, the centrally symmetrically distributed racks 606 slide on the inner wall of the concave seat 605. The racks 606 on both sides move towards each other, respectively driving the placement platform 611 to move, so that the two sides of the outer surface of the battery pack contact the inner wall of the placement platform 611, achieving positioning. The operation cylinder 612 then pushes the telescopic column 613 to move, which in turn drives the clamping plate 614. The battery pack is moved, pushing one side towards one end of the baffle 616 to stabilize it and ensure its stability during installation. The power of the first drive motor 502 is turned on, and its output drives the threaded column 503 to rotate. This causes the moving blocks 504, which are engaged with the outer surfaces of the two ends of the threaded column 503, to move towards each other. This, in turn, moves the first connecting shaft 505 and the push plate 506. The push plates 506 on both sides rotate on the outer surface of the first connecting shaft 505, raising the height of the second connecting shaft 507 and the connecting plate 508, thereby raising the height of the fixed seat 1 to facilitate battery pack installation. During the ascent, the fixed seat 1 moves the connecting block 511, which slides and is limited on the outer surface of the limiting post 510, ensuring a smooth ascent of the fixed seat 1.
