Description

Technical Field

[0001] The present application relates to the field of automobile seat shock absorbing devices, and in particular to an independent front and rear shock absorbing device for an automobile seat. Background Art

[0002] In the field of shock absorbers for most construction machinery, seat shock absorbers can only absorb and mitigate the impact of up and down vibrations, but cannot effectively absorb the impact of bumpy roads, especially the acceleration impact of uphill and downhill roads. This is because the acceleration generated by bumpy roads is in the front-to-back direction, the side direction, and the vertical direction, while the acceleration impact of uphill and downhill roads is in the vertical direction and the front-to-back direction. The front and rear shock absorption modules can absorb and mitigate the impact of uphill and downhill and bumpy roads, reducing human body damage.

[0003] The inventor believes that in actual vehicle seats, the shock-absorbing designs of vehicle seats vary greatly because different manufacturers design them based on actual costs and the comprehensive needs of application scenarios. This means that some vehicles do not have multi-directional shock-absorbing functions, resulting in a significant lack of riding comfort. Utility Model Content

[0024] The present application discloses an independent front and rear vibration reduction device for a car seat. Figure 1 , 2 , including a mounting base 1 and a shock absorbing mechanism, wherein slide rails 2 are respectively arranged on the left and right sides of the mounting base 1, and the slide rails 2 can be complete U-shaped slide rails 2, or can be front and rear segmented slide rails 2, and the shock absorbing mechanism is arranged between the two slide rails 2.

[0025] The shock absorbing mechanism includes a spring shock absorbing bracket 3, a spring assembly, a damping shock absorbing bracket 4, and a damping assembly. The spring shock absorbing bracket 3 and the damping shock absorbing bracket 4 are respectively arranged on the left and right sides of the mounting base 1. The spring shock absorbing bracket 3 and the damping shock absorbing bracket 4 are close to the corresponding slide rail 2. The spring shock absorbing bracket 3 and the damping shock absorbing bracket 4 are fixedly connected by a connecting shaft 5 arranged on the front and rear sides. Both ends of the connecting shaft 5 respectively pass through the corresponding spring shock absorbing bracket 3 and the damping shock absorbing bracket 4, and rollers that can roll in the slide rail 2 are installed at the ends.

[0026] Among them, the spring assembly is arranged on the spring shock absorber bracket 3, the damping assembly is arranged on the damping shock absorber bracket 4, and a spring assembly installation area 6 is arranged in the middle of the spring shock absorber bracket 3. In this embodiment, the spring assembly installation area 6 is a larger gap opened in the spring shock absorber bracket, and a spring fixing frame 7 is arranged on the mounting base 1 corresponding to the spring assembly installation area 6. The spring assembly is arranged between the spring fixing frame 7 and the spring shock absorber bracket 3, and the spring assembly includes a front shock absorber spring 8 and a rear shock absorber spring 9. The front end of the front shock absorber spring 8 is installed on the spring shock absorber bracket 3, and the rear end is installed on the spring fixing frame 7. The rear end of the rear shock absorber spring 9 is installed on the spring shock absorber bracket 3, and the front end is installed on the spring fixing frame 7. Here, an installation port for installing a damping spring hook can be arranged on the spring damping bracket on the front side of the spring assembly installation area 6. Similarly, an installation port for installing a damping spring hook is arranged on the spring damping bracket on the rear side of the spring assembly installation area 6, and the middle spring fixing frame 7 only needs to be provided with an installation port.

[0027] A damping component installation area 10 is arranged in the middle of the damping shock absorbing bracket 4 mentioned above. The damping component installation area 10 can be the same as the spring component installation area 6. A damping fixing frame 11 is arranged on the installation base 1 corresponding to the front or rear side of the damping installation area. The damping component is arranged between the damping fixing frame 11 and the damping shock absorbing bracket 4, wherein the damping component includes a damping rod 12 hinged on the damping shock absorbing bracket 4, and the top rod of the damping rod 12 is hinged to the damping fixing frame 11.

[0028] In order to allow users to unlock or lock the product according to different road conditions, that is, to turn the shock absorption function on and off as needed, and at the same time, to avoid excessive shock absorption stroke during the shock absorption process, the shock absorption limit assembly is used to effectively ensure the effective shock absorption stroke, and reduce unnecessary collisions between parts, thereby ensuring the safety and service life of the product.

[0029] In this embodiment, a shock absorbing locking assembly may be provided on the front side between the spring fixing frame 7 and the spring shock absorbing bracket 3 , and a shock absorbing limiting assembly may be provided on the rear side.

[0030] Among them, the shock-absorbing locking assembly includes a locking bracket 13 and a locking plate 14 respectively fixed to the corresponding positions of the spring fixing frame 7 and the spring shock-absorbing bracket 3. The locking plate 14 is hinged to the corresponding locking bracket 13. A guide slot 15 for the locking plate 14 to move forward and backward is provided on the mounting base 1 corresponding to the mounting position of the locking bracket 13. A locking slot 16 connected to the guide slot 15 is provided on the side of the guide slot 15 away from the locking bracket 13. When the locking plate 14 is in a locked state, it is locked with the locking slot 16. After the locking plate 14 and the locking slot 16 are disengaged from the locking, the locking plate 14 can move forward and backward in the guide slot 15. In order to ensure that the locking plate 14 and the locking slot 16 can maintain good stability when they are in a locked state, a return spring 17 can be provided between the ends of the two locking plates 14 passing through the guide slot 15. If in a locked state, the return spring 17 can stably lock the locking plates 14 on both sides in the corresponding locking slots 16.

[0031] The above-mentioned shock-absorbing limit assembly includes a limit bracket 18 and buffer pads 19 respectively installed on the front and rear sides of the limit bracket 18. The area between the front and rear buffer pads 19 is the activity area of ​​the rear connecting shaft 5, that is, the rear connecting shaft 5 is located between the front and rear buffer pads 19. When the rear connecting shaft 5 reaches the maximum stroke during the process of moving forward and backward with the shock-absorbing mechanism, it will contact the corresponding buffer pad 19.

[0032] When in use, the vibration reduction function is turned on or off by the switch handle to adapt to different road conditions. Generally, the switch handle can be set on the spring shock-absorbing bracket 3 or the damping shock-absorbing bracket 4, and the switch handle controls the two locking plates 14 to move closer or farther away from each other by controlling the pull wire and cooperating with the reset spring 17, thereby controlling the opening and closing of the vibration reduction mechanism, thereby adjusting the comfort of the seat to meet the needs of different road conditions, effectively improving driving comfort, and reducing the occurrence of occupational diseases.

[0033] When the independent front and rear vibration reduction device for a car seat disclosed in this embodiment is in use, when the switch handle is in an inoperative state, the return spring 17 acts as a tensioner to keep the switch handle in a stable state; at this time, a locking effect is formed between the locking plate 14 and the locking groove 16. When the locking plate 14 is separated from the locking groove 16, the vibration reduction mechanism and the roller can roll forward and backward in the slide rail 2. When the road condition has front and rear bumps or braking and other impacts, the impact force is transmitted to the spring assembly and the damping assembly. At this time, the vibration reduction spring and the damping rod 12 can absorb the impact force, providing the front and rear smoothness and comfort of the seat.

[0034] When the instantaneous impact force is very large and exceeds the energy absorption range of the shock-absorbing spring and the damping rod 12, the rear connecting shaft 5 slides backward or forward to the top of the buffer pad 19. At this time, the connecting shaft 5 of the shock-absorbing device will be limited, and the buffer pad 19 will be compressed and buffered. At this time, it can move a certain distance forward or backward to the maximum shock-absorbing stroke, thereby realizing the front and rear shock-absorbing function.

[0035] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
