Description

Technical Field

[0001] The invention relates to the technical field of automobile seat fabrics, and in particular to an automobile seat fabric with a disassembly and assembly structure. Background Art

[0002] With the rapid development of automobile technology, people's requirements for cars have gradually shifted from simple means of transportation to daily life enjoyment, thus putting forward higher and higher requirements for the functions of seats. It is precisely because people have higher and higher requirements for the functions of car seats;

[0003] At present, the publication number CN207257459U discloses a car seat headrest with a multi-layer detachable structure, including a car seat, the top of the car seat is connected to a chair headrest body through a bracket, the outer side of the chair headrest body is provided with a conjoined spring layer, the outer side of the connecting spring layer is provided with a sponge layer, and the outer side of the sponge layer is provided with a wrapping layer. By providing a Velcro male sticker and a Velcro female sticker, passengers can disassemble and assemble the disassembly layer by themselves, which is convenient and fast. By providing a cooling pad and a heat-insulating wool pad, the car seat can be replaced with a cool and heat-removing headrest in the hot summer, and the car seat can be replaced with a warm and heat-generating headrest in the cold winter. By providing a conjoined spring layer and a sponge layer, it can play a shock-absorbing role, effectively increasing the comfort of the passenger's head. By providing a hidden cavity and an inflatable bag, the gap between the passenger lying on the chair headrest body can be filled, so that the passenger's neck has a sense of support, reducing the degree of neck fatigue.

[0004] In order to solve the problem of using car seats, the existing technology adopts a method of providing hidden cavities and inflatable bags to fill the gap between the headrest bodies of the seats when the passengers lie down, thereby reducing the degree of neck fatigue. However, the backrest is inconvenient to disassemble and install, which leads to the problem that the backrest is inconvenient to clean. Summary of the invention

[0005] The object of the present invention is to provide a car seat fabric with a disassembly and assembly structure to solve the problems raised in the above background technology.

[0006] In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0007] A car seat fabric with a disassembly and assembly structure comprises a connecting portion, a mounting sleeve is installed inside the connecting portion, a backrest is installed inside the mounting sleeve, a fixing mechanism is installed at the bottom of the backrest, and a headrest is installed at one end of the backrest;

[0008] The backrest includes a connection block, which is installed inside the connection part, and one end of the connection block is fixedly connected to the backrest body;

[0009] The fixing mechanism comprises a handle, the handle is rotatably connected between the backrest and the connecting portion, one end of the handle is fixedly connected to a first rotating shaft, and one end of the first rotating shaft is fixedly connected to a first bevel gear;

[0010] The headrest comprises a sleeve block, which is fixedly connected to the top of the backrest body. A telescopic column is movably connected to the surface of the sleeve block, and the telescopic column is movably connected to the inside of the backrest body. The headrest is moved to a suitable height by moving the telescopic column.

[0011] A further improvement of the technical solution of the present invention is that one end of the first bevel tooth is fixedly connected to the second bevel tooth, one end of the second bevel tooth is fixedly connected to the second rotating shaft, and the first rotating shaft drives the first bevel tooth and the second bevel tooth to rotate with the second rotating shaft.

[0012] A further improvement of the technical solution of the present invention is that: the first rotating shaft and the second rotating shaft are rotatably connected on the surface of the connecting block, the first bevel tooth and the second bevel tooth are connected through a connecting column, one end of the connecting column is meshedly connected with a fourth bevel tooth, the fourth bevel tooth is rotatably connected to the connecting column, one end of the fourth bevel tooth is fixedly connected with a gear, the first bevel tooth and the second bevel tooth drive the gear on the fourth bevel tooth to rotate, and the gear drives the first rack to move along the limiting groove close to one end of the gear.

[0013] A further improvement of the technical solution of the present invention is that: the upper part of the gear is meshedly connected with a first rack, one end of the first rack is fixedly connected to a limiting block, the limiting block is slidably connected to the surface of the limiting groove, one end of the first rack is fixedly connected to a connecting plate, one end of the connecting plate is fixedly connected to a first fixed column, and the second rack is on the support frame and moves toward one end close to the gear, thereby driving the second fixed column and the first fixed column to detach from the mounting sleeve.

[0014] A further improvement of the technical solution of the present invention is that: the lower part of the gear is meshedly connected with a second rack, one end of the second rack is fixedly connected with a second fixing column, the second rack is slidably connected to the surface of the support frame, and the second fixing column and the first fixing column are detached from the mounting sleeve 5.

[0015] A further improvement of the technical solution of the present invention is that: a hole is opened on the surface of the telescopic column, and a fixing bolt is threadedly connected to the surface of the hole. The fixing bolt passes through and is threadedly connected to the telescopic column and the sleeve block. One end of the telescopic column is fixedly connected to a pillow. When the telescopic column is moved to an appropriate height, the fixing bolt can be rotated to threadably fix the telescopic column and the sleeve block.

[0016] Due to the adoption of the above technical solution, the present invention has the following technical advances compared with the prior art:

[0017] 1. The present invention provides a car seat fabric with a disassembly and assembly structure, wherein the handle drives the first rotating shaft to rotate, the first rotating shaft drives the first bevel gear and the second bevel gear and the second rotating shaft to rotate, the first bevel gear and the second bevel gear drive the gear on the fourth bevel gear to rotate, the gear drives the first rack to move along the limiting groove close to the end of the gear, and drives the second rack to move on the support frame to the end close to the gear, thereby driving the second fixing column and the first fixing column to separate from the installation sleeve, thereby separating from the connecting part, the connecting part is used to connect the backrest and the seat cushion, conversely, when the backrest needs to be fixed, the handle can be rotated in the opposite direction, thereby achieving a quick and convenient disassembly and fixation of the car backrest, achieving the effect of facilitating the installation of the backrest, facilitating the cleaning of the car backrest, and improving the practicality of the car seat.

[0018] 2. The present invention provides a car seat fabric with a disassembly and assembly structure. When the pillow needs to be disassembled, the fixing bolt is rotated to separate the fixing bolt from the telescopic column and the sleeve block, thereby completing the disassembly of the pillow. When the telescopic column is moved to a suitable height, the fixing bolt is rotated to thread the telescopic column and the sleeve block, thereby making it possible to flexibly adjust the height of the headrest, and fix and disassemble the headrest, thereby improving the overall convenience of the seat.
