Description

Technical Field

[0001] The utility model relates to the technical field of automobile headrests, in particular to a folding headrest with a damping structure and an automobile seat. Background Art

[0002] The seat headrest is a driving safety protection product and a comfort configuration product. It is installed on the top of the car seat backrest to provide certain support for the driver and passenger's head, provide a comfortable sitting feeling for the driver and passenger, and reduce the impact force on the passenger's neck in the event of an accident. In the prior art, the headrest is generally an integrated structure installed on the top of the backrest. In order to meet the legal requirements for the height of the headrest, the headrest usually has its own height adjustment function, which can appropriately change the installation height of the headrest in the car. High-end models have a small amount of front and rear adjustment function for the headrest.

[0003] When the rear seats are folded down, the headrests interfere with the seat cushions, often resulting in the backrests not being able to be completely flush with the trunk in height after they are folded down proportionally. The current solution is to add a flip mechanism to the headrests, which can keep the headrests upright in the use position, and can also be folded backwards and kept in the non-use position. This not only meets the height requirements of the regulations, but also increases the convenience of using the seats when folded down proportionally.

[0004] However, the existing headrest has a complex structure, redundant assembly steps during the assembly process, and assembly deviation can easily lead to poor meshing with the damping gear, resulting in potential risks of frustration and abnormal noise during folding. Utility Model Content

[0050] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, this embodiment provides a folding headrest with a damping structure, including a headrest shell 100, a headrest metal frame 200, a folding locking assembly 300, a damping gear 410 and a gear damper 420; the headrest metal frame 200 is rotatably mounted on the headrest shell 100; the folding locking assembly 300 is mounted on the headrest metal frame 200, and a button member 500 for triggering the folding locking assembly 300 is provided on the headrest shell 100; the gear damper 420 is fixedly mounted in the headrest shell 100, the damping gear 410 is fixedly sleeved on the headrest metal frame 200, and the damping gear 410 is meshed with the gear damper 420.

[0051] Specifically, when in use, the occupant presses the button member 500 on the headrest shell 100, and the button member 500 can unlock the folding locking assembly 300, so that the headrest metal frame 200 can be rotated, that is, the headrest shell 100 can be rotated relative to the headrest metal frame 200, and when the headrest shell 100 rotates, the damping gear 410 and the gear damper 420 will mesh and rotate, so that the headrest shell 100 has a damping feeling throughout the folding and rotating process, so that the headrest shell 100 folds slowly, and the internal structure of the headrest shell 100 is prevented from being damaged due to folding too quickly. In addition, the arrangement of the folding locking assembly 300, the damping gear 410 and the gear damper 420, with fewer parts, can not only ensure that the headrest shell 100 can be folded slowly, but also make the structural design simple and easy to assemble.

[0052] A rotating mounting seat 140 for mounting the headrest metal frame 200 is disposed in the headrest housing 100 .

[0053] The foldable headrest with a damping structure provided in this embodiment is used for rear seats in a car.

[0054] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, in an optional solution of this embodiment, a locking mounting seat 110 for mounting the folding locking assembly 300 is provided in the headrest shell 100, and a mounting cover 120 is provided in the headrest shell 100, and the mounting cover 120 presses the folding locking assembly 300 into the locking mounting seat 110.

[0055] Specifically, the folding locking assembly 300 is pressed tightly into the locking mounting seat 110 by installing the cover 120 , and the structure of the installed cover 120 is stable, thereby improving the stability of the folding locking assembly 300 .

[0056] The headrest metal frame 200 is installed in the headrest shell 100 through the folding locking assembly 300, and when the headrest shell 100 rotates, the rotating mounting seat 140 in the headrest shell 100 can rotate relative to the headrest metal frame 200 to avoid interference between the headrest metal frame 200 and the headrest shell 100.

[0057] The headrest metal frame 200 includes a rotating shaft 210 and a support rod 220 . Both ends of the rotating shaft 210 are connected to the support rod 220 . The rotating shaft 210 is installed in the rotating mounting seat 140 .

[0058] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, in an optional scheme of this embodiment, the folding locking assembly 300 includes a mounting bracket 310, a synchronous member 320, a locking member 330 and a trigger plate 340; both the synchronous member 320 and the locking member 330 are rotatably mounted on the mounting bracket 310, and the rotation axes 210 of the synchronous member 320 and the locking member 330 are parallel; the trigger plate 340 is rotatably mounted on the mounting bracket 310, and the rotation axis 210 of the trigger plate 340 intersects the rotation axis 210 of the locking member 330; a through hole is opened on the mounting bracket 310 for the rotation axis 210 to pass through, and the diameter of the through hole is larger than the diameter of the rotation axis 210, and the synchronous member 320 is fixedly sleeved on the rotation axis 210; the button member 500 can trigger the trigger plate 340.

[0059] The synchronous member 320 includes a synchronous wheel 321 and a first reset torsion spring 322 ; one end of the first reset torsion spring 322 is connected to the mounting bracket 310 , and the other end is connected to the synchronous wheel 321 , and the first reset torsion spring 322 is loosely sleeved on the rotating shaft 210 .

[0060] Among them, the locking member 330 includes a locking wheel 331, a locking shaft 332 and a second return torsion spring 333; the locking shaft 332 is installed on the mounting bracket 310, and the locking wheel 331 slides on the locking shaft 332; the second return torsion spring 333 is sleeved on the locking shaft 332, one end of the second return torsion spring 333 is connected to the mounting bracket 310, and the other end is connected to the locking wheel 331.

[0061] A third reset torsion spring 341 is disposed between the trigger plate 340 and the mounting bracket 310 .

[0062] Among them, the button component 500 includes a reset button 510, a driving rod 520 and a reset spring 530; the reset button 510 is installed on the headrest shell 100, and a guide groove 130 for the driving rod 520 to slide is provided in the headrest shell 100; the reset spring 530 is sleeved on the driving rod 520, and an abutment ring 521 is provided on the driving rod 520; one end of the reset spring 530 abuts against the abutment ring 521, and the other end abuts against the mounting bracket 310, and the driving rod 520 can push the trigger plate 340 to rotate.

[0063] Specifically, when the occupant presses the reset button 510, the reset button 510 can push the driving rod 520 inward, the driving rod 520 moves the compressed reset spring 530, and the front end of the driving rod 520 passes through the mounting bracket 310 and abuts against the trigger plate 340, and the driving rod 520 can drive the trigger plate 340 to rotate clockwise. At this time, the trigger plate 340 compresses the third reset torsion spring 341, and the trigger plate 340 can drive the locking wheel 331 to rotate counterclockwise. The block on the locking wheel 331 can be separated from the slot of the synchronous wheel 321. In this process, the locking wheel 331 compresses the second reset torsion spring 333, so that the synchronous wheel 321 can rotate freely. The synchronous wheel 321 rotates under the drive of the first reset torsion spring 322. Because the synchronous wheel 321 is a solid sleeve on the rotating shaft 210, the first reset torsion spring 322 can drive the mounting bracket 310 to rotate, thereby driving the headrest shell 100 to rotate. When the occupant releases the resettable button 510, the resettable button 510 is automatically reset, and both the trigger plate 340 and the locking wheel 331 are automatically reset. When the occupant manually resets the headrest shell 100, the locking wheel 331 rotates with the headrest shell 100. When the headrest shell 100 is reset, the locking wheel 331 can be engaged with the synchronous wheel 321, and the first reset torsion spring 322 will be compressed during this process.

[0064] The folding headrest with a damping structure provided in this embodiment can ensure that the headrest has a damping feeling throughout the entire folding stroke. After the headrest is unlocked from the locked position, the damping gear 410 and the gear damper 420 are fully engaged, effectively ensuring a slow folding effect during the full folding stroke recovery process.

[0065] In addition, the setting of the installation cover 120 can reduce the probability of potential failure. The folding locking assembly 300 is fixedly installed on the headrest shell 100 through the installation cover 120, which increases the force-bearing area, can reduce the stress concentration point during the flipping process, and the product design stability is higher.

[0066] In addition, the damping gear 410 and the gear damper 420 have a high degree of structural integration and require a small space, which is more conducive to structural layout and product structure platformization.

[0067] This embodiment provides a car seat, including a folding headrest with a damping structure.

[0068] Specifically, compared with the prior art, the automobile seat has the advantages of the folding headrest with the damping structure, which will not be described in detail here.

[0069] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in the field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the utility model.
