Description

Technical Field

[0001] This utility model relates to a seat frame, specifically a lightweight electric vehicle seat frame, and belongs to the technical field of electric vehicle seat frame. Background Technology

[0002] Electric vehicles are a type of transportation tool, characterized by their lightweight design, ease of operation, and convenient mobility. They are mainly divided into two-wheeled and three-wheeled types with different numbers of wheels and are an important component of family transportation tools.

[0003] Electric vehicle seats are installed inside three-wheeled or four-wheeled mobility scooters. These seats mainly consist of a frame and a cushion. The cushion improves the user's operating experience. Existing cushions are generally made of imitation leather, which accumulates oil and other impurities after prolonged use. Therefore, users install protective covers on the outside of the seat. These covers are made of non-slip, wear-resistant fabric and are secured using mounting straps. However, these straps subject the covers to tensile forces in various directions, causing the connection between the straps and the cover to tear and loosen. Furthermore, installation with straps relies on the user's experience, requiring the cover to be pulled taut, making installation inconvenient and hindering quick installation and replacement. Therefore, we provide a lightweight electric vehicle seat frame to solve these problems. Utility Model Content

[0004] To address the aforementioned problems, this utility model provides a lightweight electric vehicle seat frame, the specific technical solution of which is as follows:

[0005] A lightweight electric vehicle seat frame includes a base with a storage cavity inside. A fixed shaft is rotatably connected inside the base, and a fixed frame is rotatably connected to the outer surface of the fixed shaft. A mounting seat is slidably connected inside the fixed frame, and a seat cushion is mounted on the outside of the mounting seat. Multiple sets of limiting rods are fixedly installed inside the mounting seat, and support plates are fixedly installed on the outer surfaces of each of the multiple sets of limiting rods. A control rod is rotatably connected inside the support plate, and a pressure plate is threadedly connected to the outer surface of the control rod. A toothed plate is fixedly installed on the outer surface of the pressure plate, and a second toothed plate is fixedly installed inside the fixed frame.

[0006] Preferably, a baffle is fixedly installed on the inner wall of the storage cavity, the outer surface of the fixing frame is in contact with the outer surface of the baffle, a positioning frame is installed on the outside of the fixing frame, the outer surface of the positioning frame is slidably connected to the inside of the base, and multiple sets of protective frames are installed on the outside of the base.

[0007] Preferably, a reinforcing plate is fixedly installed on the inner wall of the mounting base, the outer surface of the control rod is sleeved with the inside of the mounting base, multiple sets of the limiting rods are arranged in a ring array outside the control rod, and a rotating handle is fixedly installed on the outer surface of the control rod.

[0008] Preferably, multiple sets of toothed plates are provided for both toothed plate one and toothed plate two, and toothed plate one and toothed plate two can mesh with each other when the pressure plate moves, and the pressure plate has an L-shaped structure.

[0009] Preferably, a fixing rod is slidably connected inside the pressure plate, and a spring is sleeved on the outside of the fixing rod, with both ends of the spring connected to the outside of the pressure plate and the fixing rod, respectively.

[0010] Preferably, the mounting base has a limiting groove inside, the outer surface of the fixing rod is slidably connected to the inside of the limiting groove, and the mounting base has a limiting hole inside, the outer surface of the fixing rod is slidably connected to the inside of the limiting hole.

[0011] Preferably, the base has a second limiting hole inside, and the outer surface of the fixing rod is slidably connected to the inside of the second limiting hole.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. This lightweight electric vehicle seat frame, through the cooperation of a control lever, pressure plate, toothed plate one, and toothed plate two, features a detachable mounting base. When installing the protective cover, the mounting base is first removed. The protective cover is then folded from each side of the seat cushion, and excess material is tucked into the mounting base. The control lever moves the pressure plate, which then compresses the protective cover's material. The connection between toothed plate one and toothed plate two securely fixes the protective cover, ensuring its stability during use. Conversely, the protective cover can be quickly disassembled. This allows for rapid installation and replacement of the protective cover on the seat cushion, making it convenient for users.

[0014] 2. This lightweight electric vehicle seat frame incorporates components such as springs and fixing rods. When the pressure plate moves, the fixing rod can slide inside the limiting groove. After toothed plate one and toothed plate two engage to fix the protective sleeve, the fixing rod moves to the position of limiting hole one. At this time, the spring can push the fixing rod to move through limiting hole one into the interior of limiting hole two. Thus, the fixing rod, limiting hole one, and limiting hole two can stably fix the mounting seat inside the base, ensuring the stability of the mounting seat during fixing.

[0015] 3. This lightweight electric vehicle seat frame incorporates components such as an L-shaped pressure plate. The L-shaped structure allows for the simultaneous fixation of the protective sleeve at right-angle positions inside the mounting base. This multi-position fixation ensures the stability of the protective sleeve during fixation. The limit rod controls the pressure plate to move diagonally within the mounting base. When the protective sleeve is folded, the resulting right-angled edge material can be placed into the space diagonally between the pressure plate and the mounting base, making it more convenient to use.

[0022] The present invention will now be further described with reference to the accompanying drawings.

[0023] Please see Figure 1 - Figure 5 A lightweight electric vehicle seat frame includes a base 1, with a storage cavity 2 inside the base 1. A fixed shaft 3 is rotatably connected inside the base 1, and a fixed frame 4 is rotatably connected to the outer surface of the fixed shaft 3. Under the action of the fixed shaft 3, the fixed frame 4 can be rotated open, at which time items can be stored inside the storage cavity 2.

[0024] A baffle 13 is fixedly installed on the inner wall of the storage cavity 2. The outer surface of the fixing frame 4 is in contact with the outer surface of the baffle 13. The baffle 13 can limit the position of the fixing frame 4 and provide auxiliary support for the fixing frame 4, ensuring the stability of the fixing frame 4 during use. A positioning frame 14 is installed on the outside of the fixing frame 4. The outer surface of the positioning frame 14 is slidably connected to the inside of the base 1. The positioning frame 14 is connected and fixed to the base 1 by an external buckle, ensuring the stability during use. Multiple sets of protective frames 15 are installed on the outside of the base 1, which can protect the user's outside.

[0025] The mounting bracket 4 has a sliding connection to the mounting base 5, and a cushion 6 is installed on the outside of the mounting base 5. The mounting base 5 can be disassembled, and the mounting base 5 and the cushion 6 can be removed as a whole. The mounting base 5 and the mounting bracket 4 are not fixed with multiple sets of fixing bolts, making disassembly and installation more convenient. A reinforcing plate 16 is fixedly installed on the inner wall of the mounting base 5. The reinforcing plate 16 can provide auxiliary support for the interior of the mounting base 5, increasing the load-bearing capacity of the overall frame during use.

[0026] Multiple sets of limiting rods 7 are fixedly installed inside the mounting base 5. Support plates 8 are fixedly installed on the outer surfaces of the multiple sets of limiting rods 7. Control rods 9 are rotatably connected inside the support plates 8. The multiple sets of limiting rods 7 are arranged in a ring array outside the control rods 9. The outer surface of the control rods 9 is sleeved with the inside of the mounting base 5. A rotating handle 17 is fixedly installed on the outer surface of the control rods 9. The auxiliary limiting of the support plates 8 can provide stable support for the outside of the control rods 9, ensuring the stability of the control rods 9 when rotating.

[0027] The outer surface of the control lever 9 is threaded with a pressure plate 10. The outer surface of the limit lever 7 is slidably connected to the inside of the pressure plate 10. The pressure plate 10 has an L-shaped structure. Under the control of the control lever 9, both sides of the pressure plate 10 can approach each other with the inner wall of the mounting base 5. The rotation of the control lever 9 can also move the sides of the pressure plate 10 synchronously.

[0028] A toothed plate 11 is fixedly installed on the outer surface of the pressure plate 10, and a toothed plate 2 12 is fixedly installed inside the fixing frame 4. Multiple sets of toothed plates 11 and 2 12 are provided. When the pressure plate 10 moves, toothed plates 11 and 2 12 can mesh with each other. When installing the protective cover, first cover the outside of the cushion 6 with the protective cover, and then put the excess part of the protective cover into the inside of the mounting base 5. At this time, rotate the control lever 9 to bring toothed plates 11 and 2 12 closer together. The meshing of the teeth of toothed plates 11 and 2 12 can fix the excess edge material of the protective cover. There is no need to use the installation belt for binding installation, making the installation more stable and the use more reliable.

[0029] A fixed rod 18 is slidably connected inside the pressure plate 10. A spring 19 is sleeved on the outside of the fixed rod 18. The two ends of the spring 19 are respectively connected to the outside of the pressure plate 10 and the fixed rod 18. A limiting groove 20 is opened inside the mounting base 5. The outer surface of the fixed rod 18 is slidably connected to the inside of the limiting groove 20. A limiting hole 21 is opened inside the mounting base 5. The outer surface of the fixed rod 18 is slidably connected to the inside of the limiting hole 21. When the pressure plate 10 moves, the fixed rod 18 will move elastically under the action of the spring 19. At this time, the fixed rod 18 will slide inside the limiting groove 20. When the fixed rod 18 moves to the position of the limiting hole 21, the fixed rod 18 will enter the inside of the limiting hole 21 under the push of the spring 19.

[0030] The base 1 has a second limiting hole 22 inside. The outer surface of the fixing rod 18 is slidably connected to the inside of the second limiting hole 22. When the mounting base 5 is placed, the fixing rod 18 can be inserted into the inside of the second limiting hole 22. At this time, the connection between the first limiting hole 21 and the second limiting hole 22 can stably fix the mounting base 5 inside the fixing frame 4, making installation and disassembly more convenient.

[0031] The electrical equipment in this application is a common type of electrical equipment in the prior art. This application will not elaborate on its model or internal structure. It can also be replaced by other power sources.

[0032] When using this utility model: First, control the rotation of the fixing frame 4 to install the protective cover. After disconnecting the connection between the fixing rod 18 and the second limiting hole 22, the mounting base 5 can be removed. At this time, the pressure plate 10 is far away from the inside of the mounting base 5. Place the protective cover fabric on the outside of the cushion 6 and place the edge material of the protective cover between the mounting base 5 and the pressure plate 10. By rotating the control rod 9, the pressure plate 10 can be moved. At this time, the pressure plate 10 drives the toothed plate 11 and the toothed plate 12 to move closer to each other. Through the meshing of the gear teeth of the toothed plate 11 and the toothed plate 12, the edge material of the protective cover can be pressed and fixed. After the mounting base 5 is placed inside the fixing frame 4, the spring 19 can push the fixing rod 18 to move. At this time, the fixing rod 18 can enter the inside of the second limiting hole 22, which can stably fix the mounting base 5 inside the base 1.
