Description

Technical Field

[0001] This utility model relates to a frame mechanism, and more particularly to an electric frame mechanism with a telescopic floor lock function, which is a component of a car seat. Background Technology

[0002] In the prior art, the electric seat frame structure for automobiles includes a seat cushion frame, a four-quarter backrest frame, and a six-quarter backrest frame, with the seat cushion frame fixed to both the four-quarter backrest frame and the six-quarter backrest frame.

[0003] Typically, this type of electric car seat frame has the following disadvantages during use: 1) The original floor lock is fixed and cannot be hidden or extended, resulting in poor aesthetics; 2) The floor lock is exposed, making it easy to collide with people and cause injury, creating a safety hazard.

[0004] Therefore, it is particularly necessary to provide an electric frame mechanism with a safe and reasonable structural design, in which the floor lock can be retracted and hidden within the seat cushion frame. Utility Model Content

[0005] The purpose of this utility model is to overcome the above-mentioned shortcomings in the existing technology and to provide an electric frame mechanism with a telescopic floor lock function that has a safe and reasonable structural design, is stable and reliable, and has a floor lock that can be telescopically hidden inside the seat cushion frame, thus making high space utilization.

[0006] The technical solution adopted by this utility model to solve the above problems is as follows: The electric frame mechanism with telescopic floor lock function includes a seat cushion frame, a four-quarter backrest frame, a six-quarter backrest frame, a four-quarter angle adjuster, and a six-quarter angle adjuster. The seat cushion frame is fixed to the four-quarter backrest frame and the six-quarter backrest frame respectively through the four-quarter angle adjuster and the six-quarter angle adjuster. The seat cushion frame includes a frame body, a floor lock assembly, a flip assembly, an unlocker, a pull cable one, and a pull cable two. The floor lock assembly is mounted on the frame body. The flip assembly is connected to the main shaft inside the frame body. One end of the floor lock assembly is connected to the unlocker through pull cable two, and the other end of the floor lock assembly is connected to the flip assembly through pull cable one. The floor lock assembly includes a lock bracket, a spring, a floor lock, and a bracket shaft. The bracket shaft is fixed to the frame body, the lock bracket can rotate around the bracket shaft, and a spring is installed inside the lock bracket. The floor lock is fixed to the lock bracket.

[0007] Preferably, one end of the pull wire is fixedly connected to the flipping component, and the other end of the pull wire is connected to the lock bracket.

[0008] Preferably, one end of the pull cord 2 is connected to the unlocker, and the other end of the pull cord 2 is connected to the unlocking component of the floor lock.

[0009] Preferably, the seat frame of this invention also includes a locking ring fixed to the external vehicle floor, which engages with a floor lock in the floor lock assembly.

[0010] Compared with the prior art, this utility model has the following advantages and effects: the overall structure is reasonably designed and safe and reliable. When the seat frame is in a horizontal state, the floor lock component can extend and lock in place with the lock ring. When the seat frame is in a vertical state, it can be retracted into the seat frame for a neat and aesthetically pleasing concealment. In other words, the floor lock can be extended and hidden inside the seat frame, resulting in high space utilization and meeting usage requirements. Attached Figure Description

[0022] The present invention will be further described in detail below with reference to the accompanying drawings and through embodiments. The following embodiments are explanations of the present invention, but the present invention is not limited to the following embodiments.

[0023] Example

[0024] See Figures 1 to 8 The electric frame mechanism with telescopic floor lock function in this embodiment includes a seat frame 1, a four-quarter backrest frame 2, a six-quarter backrest frame 3, a four-quarter angle adjuster 21 and a six-quarter angle adjuster 31. The seat frame 1 is fixed to the four-quarter backrest frame 2 and the six-quarter backrest frame 3 by the four-quarter angle adjuster 21 and the six-quarter angle adjuster 31, respectively.

[0025] In this embodiment, the seat cushion frame 1 includes a frame body 11, a floor lock assembly 12, a flip assembly 13, an unlocker 14, a pull cable 15, a locking ring 16, and a pull cable 17. There are two floor lock assemblies 12, and both floor lock assemblies 12 are fixed to the frame body 11. One end of the floor lock assembly 12 is connected to the unlocker 14 through the pull cable 17, and the other end of the floor lock assembly 12 is connected to the flip assembly 13 through the pull cable 15. The flip assembly 13 and the locking ring 16 are both fixed to the vehicle floor.

[0026] In this embodiment, a main shaft is provided inside the frame body 11. The main shaft is connected to the flipping component 13, and the center of the flipping component 13 is the rotation center of the skeleton.

[0027] In this embodiment, the floor lock assembly 12 includes a lock bracket 121, a spring 122, a floor lock 123, and a bracket shaft 124. The bracket shaft 124 in the floor lock assembly 12 is fixed to the frame body 11 in the cushion frame 1. The lock bracket 121 can rotate around the bracket shaft 124. Two springs 122 are provided inside the lock bracket 121. The floor lock 123 is fixed on the lock bracket 121.

[0028] In this embodiment, one end of the pull wire 15 is fixedly connected to the flipping component 13. After the seat frame 1 moves, the pull wire 15 is tightened, and the other end of the pull wire 15 is connected to the lock bracket 121.

[0029] In this embodiment, one end of the pull wire 17 is connected to the unlocker 14, and the other end of the pull wire 17 is connected to the unlocking component of the floor lock 123.

[0030] In this embodiment, the floor lock 123 is equipped with its own spring, and the locking ring 16 cooperates with the floor lock 123.

[0031] The working process of the electric frame mechanism with telescopic floor lock function in this embodiment is as follows: Drive the unlocker 14, and unlock the floor lock 123 through the pull cable 17. Driven by the motor in the flip assembly 13, the seat frame 1 flips vertically backward. During the flip, the lock bracket 121 is pulled by the pull cable 15 to flip, so that the back of the lock bracket 121 fits against the back of the seat frame 1, achieving concealment and making the overall appearance more aesthetically pleasing. When the flip assembly 13 is driven in the reverse direction, it gradually reaches a horizontal state. At this time, the pull cable 15 is released, and the two springs 122 in the lock bracket 121 extend under the action. After reaching the position, it continues to flip and cooperates with the locking ring 16 to achieve locking.

[0032] Based on the above description, those skilled in the art are already able to implement it.
