Description

Technical Field

[0001] The utility model relates to the technical field of electric vehicles, in particular to a seat of an electric vehicle. Background Art

[0002] Electric vehicles are favored by low- and middle-income urban residents for their affordability, convenience, and environmental friendliness. Electric vehicles are increasingly occupying a larger share of the national economy. They align with national energy conservation and environmental protection initiatives, greatly facilitating short-distance transportation and, most importantly, playing a significant role in the national economy through energy conservation and environmental protection. The electric vehicle seat is a load-bearing platform, the seat for riders, and an essential component of an electric vehicle, making its selection crucial.

[0003] After long-term use, existing electric vehicle seats can experience external damage, deformation, and internal damage to the upper sponge cushion. Furthermore, the sponge cushion is typically attached directly to the seat, making it impossible to replace the cushion alone during repairs. The entire seat must be replaced, significantly increasing repair costs. Therefore, there is an urgent need to design an electric vehicle seat that addresses these issues. Utility Model Content

[0004] The purpose of the present invention is to provide an electric vehicle seat to solve the above-mentioned deficiencies in the prior art.

[0005] In order to achieve the above purpose, the present invention provides the following technical solutions:

[0006] A seat for an electric vehicle comprises a seat body, the seat body comprising a sponge seat cushion and a mounting base, a fixing mechanism being arranged in the mounting base, the fixing mechanism comprising a bidirectional threaded rod, a threaded slide, a clamping block and a plug-in block, a mounting cavity being provided in the mounting base, the bidirectional threaded rod being rotatably mounted in the mounting cavity, the threaded slide being threadedly connected to the bidirectional threaded rod, the clamping block being fixedly mounted on one side of the threaded slide, a plug-in groove being provided on the upper side of the mounting base, the plug-in block being arranged on the lower side of the sponge seat cushion, the plug-in block being plugged into the plug-in groove, and the clamping block cooperating with the plug-in block.

[0007] Rotating rods are rotatably mounted on both sides of the inner wall of the installation cavity, a worm is fixedly mounted between the two rotating rods, a worm wheel is fixedly mounted on the middle section of the bidirectional threaded rod, and the worm is meshed with the worm wheel.

[0008] An insertion hole is provided on one side of the mounting base, the insertion hole corresponds to one of the rotating rods, and a special-shaped insertion hole is provided on one end of the rotating rod.

[0009] There are two threaded slides, which are respectively located at both ends of the bidirectional threaded rod. There are four clamping blocks and four plug-in blocks. Two guide rods are fixedly installed in the installation cavity, and the threaded slides are slidably connected to the guide rods.

[0023] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0024] like Figure 1-5 As shown, an electric vehicle seat provided by an embodiment of the present invention includes a seat body 1, the seat body 1 includes a sponge seat cushion 2 and a mounting base 3, a fixing mechanism 4 is provided in the mounting base 3, the fixing mechanism 4 includes a bidirectional threaded rod 12, a threaded slide 13, a clamping block 14 and a plug-in block 5, a mounting cavity 11 is provided in the mounting base 3, the bidirectional threaded rod 12 is rotatably mounted in the mounting cavity 11, the threaded slide 13 is threadedly connected to the bidirectional threaded rod 12, the clamping block 14 is fixedly mounted on one side of the threaded slide 13, a plug-in slot 8 is provided on the upper side of the mounting base 3, the plug-in block 5 is provided on the lower side of the sponge seat cushion 2, and the plug-in block 5 is plugged into the plug-in slot In the groove 8, the clamping block 14 cooperates with the plug-in block 5, and rotating rods 16 are rotatably installed on both sides of the inner wall of the installation cavity 11. A worm 18 is fixedly installed between the two rotating rods 16. A worm gear 17 is fixedly installed in the middle section of the bidirectional threaded rod 12, and the worm 18 is engaged with the worm gear 17. There are two threaded slides 13, and the two threaded slides 13 are respectively located at both ends of the bidirectional threaded rod 12. There are four clamping blocks 14 and four plug-in blocks 5. Two guide rods 15 are fixedly installed in the installation cavity 11, and the threaded slides 13 are slidably connected to the guide rods 15. A clamping groove 6 is opened on one side of the plug-in block 5, and the clamping block 14 is movably plugged into the clamping groove 6.

[0025] Specifically, in this embodiment, the worm 18 is driven to rotate by rotating the rotating rod 16, and the rotation of the worm 18 can drive the worm wheel 17 to rotate. The rotation of the worm wheel 17 can drive the bidirectional threaded rod 12 to rotate. The rotation of the bidirectional threaded rod 12 can drive the two threaded slides 13 to move at the same time. The movement of the threaded slide 13 can drive the clamping block 14 to move, so that the clamping block 14 disengages from the plug-in slot 8 on one side of the plug-in block 5, thereby releasing the fixed limit of the sponge seat cushion 2, and then pulling the sponge seat cushion 2 upward, so that the sponge seat cushion 2 drives the plug-in block 5 to disengage from the plug-in slot 8 on the upper side of the mounting base 3, and the sponge seat cushion 2 can be removed. When installing, the plug-in slot on the lower side of the new sponge seat cushion 2 can be installed by reversing the above steps. The block 5 is inserted into the plug-in slot 8, and then the rotating rod 16 is rotated to drive the worm 18 to rotate, so that the worm 18 drives the worm wheel 17 and the bidirectional threaded rod 12 to rotate, and the rotation of the bidirectional threaded rod 12 drives the threaded slide 13 and the clamping block 14 to move, so that the clamping block 14 is inserted into the plug-in slot 8 on one side of the plug-in block 5, and then the sponge seat cushion 2 can be installed and fixed. The self-locking function is achieved through the structural characteristics of the bidirectional threaded rod 12 and the threaded slide 13, as well as the worm 18 and the worm wheel 17, thereby ensuring the stability of the clamping block 14 after being inserted into the plug-in slot 8 on one side of the plug-in block 5. The guide rod 15 can increase the smoothness of the threaded slide 13 when sliding, and avoid the threaded slide 13 from getting stuck when sliding.

[0026] The utility model provides an electric vehicle seat, wherein an insertion hole 10 is opened on one side of the mounting base 3, the insertion hole 10 corresponds to one of the rotating rods 16, and a special-shaped insertion hole is opened at one end of the rotating rod 16, a limiting plate 7 is provided on the lower side of the sponge seat cushion 2, a limiting groove 9 is opened on the upper side of the mounting base 3, the limiting plate 7 is inserted into the limiting groove 9, and the plug-in block 5 is fixedly installed on the lower side of the limiting plate 7.

[0027] In another embodiment provided by the present invention, the vehicle seat is equipped with a key that is adapted to the shape of the special-shaped socket. By inserting the key into the insertion hole 10 and into the special-shaped socket, and then turning the key, the key drives the rotating rod 16 to rotate, thereby avoiding setting one end of the rotating rod 16 on the outside of the mounting base 3, and someone accidentally touching the rotating rod 16 during driving, causing the rotating rod 16 to drive the fixing mechanism to rotate, resulting in the sponge seat cushion 2 being unfixed from the mounting base 3, and avoiding unrelated personnel from disassembling the sponge seat cushion 2, thereby improving the safety of the vehicle seat when in use, wherein the sponge seat cushion 2 is composed of an outer wrapping layer and an inner sponge layer, and the outer wrapping layer is fixed to the limiting plate 7 on the periphery, so that the outer wrapping layer wraps and fixes the sponge layer between the outer wrapping layer and the limiting plate 7.
