Description

Technical Field

[0001] This utility model belongs to the field of automotive seat technology, and in particular relates to a high-adjustment structure for automotive seat cushions without torsion bars. Background Technology

[0002] As cars are the most common means of transportation in people's lives, the comfort and convenience of riding in them are naturally improving. As a major component of a car, car seats also need to be improved, and electric seats are now extremely common, offering greater comfort and convenience.

[0003] See the attached instruction manual. Figures 4 to 6 Currently, most electric high-adjustment structures used in cars employ a motor in conjunction with a torsion bar. This structure requires counteracting the torsion bar's own torque when adjusting upwards or downwards, inevitably leading to imbalance noise. Furthermore, installing the torsion bar and its fixing bushing is a complex assembly process for manufacturers, inevitably reducing production efficiency. Therefore, this invention proposes a torsion bar-free high-adjustment structure for car seat cushions to solve the aforementioned problems. Utility Model Content

[0004] This invention provides a torsion bar-free high-adjustment structure for automotive seat cushions, aiming to solve the problems mentioned in the background art.

[0005] This utility model is implemented as follows: a torsion bar-free high-adjustment structure for car seat cushions, including a right seat cushion side plate, a left seat cushion side plate, a rear cross tube, a high-adjustment motor, a high-adjustment toothed plate, a rear high-adjustment connecting rod, and a motor fixing sheet metal.

[0006] The right and left seat cushion side panels are arranged opposite each other. The high-adjustment motor is equipped with a stud and is located on the outer wall of the left seat cushion side panel. The high-adjustment motor drives the high-adjustment toothed plate to rotate. The rear horizontal tube is provided between the right and left seat cushion side panels and is rotatably connected to the right and left seat cushion side panels. The high-adjustment toothed plate is fixedly connected to the rear horizontal tube, and the rear high-adjustment connecting rod is fixedly connected to the rear horizontal tube. The high-adjustment toothed plate and the rear high-adjustment connecting rod are distributed opposite each other.

[0007] Preferably, the output end of the high-adjustment motor is a gear structure, and the output end of the high-adjustment motor is meshed with the gear end of the high-adjustment gear plate.

[0008] Preferably, the high-adjustment toothed plate is located between the left side seat cushion plate and the motor fixing sheet metal.

[0009] Preferably, the motor mounting sheet metal is provided with screw holes, and the studs on the high-speed motor pass through the screw holes and are fixedly connected to the motor mounting sheet metal by bolts.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] 1. The electric vehicle seat features a torsion bar-free seat cushion high-adjustment structure. It adopts a torsion bar-free design, so it does not need to overcome the torque of the torsion bar itself when moving downwards (or upwards), thus avoiding imbalance noise problems and reducing the risk of abnormal noise.

[0012] 2. Although a high-torque motor (high-adjustment motor) is required to prevent insufficient torque when adjusting upwards (or downwards), and the high-torque motor (high-adjustment motor) is slightly more expensive than a regular motor, it eliminates the cost of torsion bars and torsion bar fixing bushings. The subsequent installation process of torsion bars and torsion bar fixing bushings is also eliminated, simplifying the entire installation process. Therefore, overall, the cost and economy are improved. Attached Figure Description

[0026] Example:

[0027] Please see Figures 1 to 3 This utility model provides a technical solution: a torsion bar-free height adjustment structure for car seat cushions, including a right seat cushion side plate 1, a left seat cushion side plate 2, a rear cross tube 3, a height adjustment motor 4, a height adjustment toothed plate 5, a rear height adjustment connecting rod 6, and a motor fixing sheet metal 7; the right seat cushion side plate 1 and the left seat cushion side plate 2 are arranged opposite to each other, the height adjustment motor 4 is provided with a stud, the height adjustment motor 4 is located on the outer wall of the left seat cushion side plate 2, the height adjustment motor 4 drives the height adjustment toothed plate 5 to rotate, the rear cross tube 3 is provided between the right seat cushion side plate 1 and the left seat cushion side plate 2, the rear cross tube 3 is rotatably connected to the right seat cushion side plate 1 and the left seat cushion side plate 2, the height adjustment toothed plate 5 is fixedly connected to the rear cross tube 3, the rear height adjustment connecting rod 6 is fixedly connected to the rear cross tube 3, and the height adjustment toothed plate 5 and the rear height adjustment connecting rod 6 are distributed opposite to each other.

[0028] For further details, please refer to Figure 2The output end of the high-adjustment motor 4 is a gear structure, and the output end of the high-adjustment motor 4 is meshed with the gear end of the high-adjustment gear plate 5.

[0029] For further details, please refer to Figure 2 The high-profile toothed plate 5 is located between the left side seat cushion plate 2 and the motor fixing sheet metal 7.

[0030] For further details, please refer to Figure 2 and Figure 3 The motor mounting sheet metal 7 has screw holes. The studs on the high-speed motor 4 pass through the screw holes and are fixedly connected to the motor mounting sheet metal 7 by bolts.

[0031] In this embodiment, the entire high-adjustment structure is set between the right side seat cushion panel 1 and the left side seat cushion panel 2. The high-adjustment motor 4 is fixed to the left side seat cushion panel 2 by bolts through the motor fixing sheet metal 7 and the studs on the high-adjustment motor 4 itself.

[0032] The high-adjustment motor 4 is a high-torque motor. The entire high-adjustment structure drives the high-adjustment gear plate 5 through the high-torque motor, which in turn drives the rear cross tube 3 to rotate, thereby driving the rear high-adjustment linkage 6 on the other side to rotate, thus realizing the upward or downward movement of the seat.

[0033] When the seat cushion height needs to be adjusted, the height adjustment motor 4 is controlled by a switch. The height adjustment motor 4 is a high-torque motor. The output of the height adjustment motor 4 drives the height adjustment gear plate 5 to rotate. The rotation of the height adjustment gear plate 5 drives the rear cross tube 3 to rotate. At the same time, the rotation of the rear cross tube 3 drives the rear height adjustment linkage 6 to rotate, thereby controlling the rotation of the entire height adjustment structure. The height adjustment motor 4 is set to rotate forward, driving the height adjustment gear plate 5 to rotate upward, thus realizing the upward rotation of the entire height adjustment structure. The height adjustment motor 4 is set to rotate in reverse, driving the height adjustment gear plate 5 to rotate downward, thus realizing the downward rotation of the entire height adjustment structure.

[0034] Comparative example:

[0035] Please see Figures 4 to 6 An existing high-adjustment structure for car seat cushions without torsion bars includes a right seat cushion side plate 1, a left seat cushion side plate 2, a rear cross tube 3, a high-adjustment motor 4, a high-adjustment toothed plate 5, a rear high-adjustment connecting rod 6, a motor fixing sheet metal 7, a torsion bar 8, and a torsion bar fixing bushing 9.

[0036] Among them, the right side seat cushion panel 1 and the left side seat cushion panel 2 are arranged opposite to each other. The high-adjustment motor 4 is located on the outer wall of the left side seat cushion panel 2. The high-adjustment motor 4 drives the high-adjustment tooth plate 5 to rotate. The torsion bar 8 is connected to the rear horizontal tube 3 through the torsion bar fixing bushing 9. The rear horizontal tube 3 is located between the right side seat cushion panel 1 and the left side seat cushion panel 2.

[0037] When the seat cushion height needs to be adjusted, the height adjustment motor 4 is controlled by a switch. The output of the height adjustment motor 4 drives the height adjustment gear plate 5 to rotate (forward or reverse). The rotation of the height adjustment gear plate 5 drives the rear cross tube 3 to rotate (forward or reverse). The forward rotation of the rear cross tube 3 drives the rear height adjustment linkage 6 to rotate, controlling the entire height adjustment structure to rotate upward. At this time, the torsion bar 8 deforms. The torsion bar 8 inevitably produces an imbalance noise due to its own torque. Similarly, the reverse rotation of the rear cross tube 3 drives the rear height adjustment linkage 6 to rotate, controlling the entire height adjustment structure to rotate downward. At this time, the restoring force of the torsion bar 8 (during the restoring process) will provide an assist to the height adjustment motor 4. At the same time, after the torsion bar 8 returns to its original position, it will also deform (in the opposite direction). The torsion bar 8 will inevitably produce an imbalance noise due to its own torque. Although the restoring force of the torsion bar 8 can provide an assist to the height adjustment motor 4, it will also cause abnormal noise.

[0038] Comparison of Examples and Comparative Examples:

[0039] The contrast ratio is the high-adjustment structure of electric seats currently used in cars on the market, which uses a high-adjustment motor 4 in conjunction with a torsion bar 8. Although the torsion bar 8 assists the high-adjustment motor 4 when adjusting upwards (or downwards), it is necessary to counteract the torsion of the torsion bar 8 itself when adjusting downwards (or upwards), which inevitably produces imbalance noise problems. Moreover, for manufacturers, installing the torsion bar 8 and the torsion bar fixing bushing 9 is also a relatively complex assembly process, which inevitably reduces production efficiency.

[0040] The electric vehicle seat cushion high-adjustment structure without torsion bar provided in this embodiment adopts a design without torsion bar 8. Downward (or upward) adjustment does not require overcoming the torque of torsion bar 8 itself, thus avoiding imbalance noise issues and reducing the risk of noise generation. Simultaneously, although a high-torque motor (high-adjustment motor 4) is needed to prevent insufficient torque during upward (or downward) adjustment, the high-torque motor can replace the assist function of torsion bar 8. Although the high-torque motor (high-adjustment motor 4) is slightly more expensive than a regular motor, it eliminates the cost of torsion bar 8 and torsion bar fixing bushing 9. The subsequent installation process of torsion bar 8 and torsion bar fixing bushing 9 is also eliminated, simplifying the entire installation process. Therefore, overall, the cost and economic efficiency are improved.

[0041] The working principle and usage process of this utility model are as follows: When it is necessary to adjust the height of the seat cushion, the height adjustment motor 4 is controlled by a switch. The height adjustment motor 4 is a high-torque motor. The output end of the height adjustment motor 4 drives the height adjustment gear plate 5 to rotate. The rotation of the height adjustment gear plate 5 drives the rear horizontal tube 3 to rotate. At the same time, the rotation of the rear horizontal tube 3 drives the rear height adjustment connecting rod 6 to rotate, thereby controlling the rotation of the entire height adjustment structure. The height adjustment motor 4 is set to rotate forward to drive the height adjustment gear plate 5 to rotate upward, thereby realizing that the forward rotation of the height adjustment motor 4 controls the upward rotation of the entire height adjustment structure. The height adjustment motor 4 is set to rotate in reverse to drive the height adjustment gear plate 5 to rotate downward, thereby realizing that the reverse rotation of the height adjustment motor 4 controls the downward rotation of the entire height adjustment structure.

[0042] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
