Abstract
Description
Technical Field
[0001] This utility model relates to the field of automotive parts technology, and in particular to an adjustment handle, a seat adjuster using the same, and an automotive seat. Background Technology
[0002] A seat back adjuster is a device installed on a car seat to adjust the seat back angle. It typically consists of a backrest connecting plate, a seat seat connecting plate, a core component, a handwheel or adjustment handle, and a return spring. The adjuster is usually installed in the area where the seat back and seat cushion meet. Car seat adjusters are used to adjust the direction of the seat back, allowing for different adjustments based on age and individual needs, thus improving comfort when using the car seat.
[0003] For example, CN222610979U discloses a car seat adjuster handle, including a handle shell. The handle shell has a circular surface at its left end with a connecting hole. The center of the connecting hole has a slot, and inside the connecting hole is a connecting tube. The connecting tube is a rectangular groove tube, and its outer arc surface has a dispersion plate located inside the slot. Both the connecting tube and the dispersion plate are made of aluminum alloy. The handle shell is made of polypropylene plastic. A baffle is inserted into the connecting hole, and the rear side of the baffle has an elastic locking plate that engages with a slot at the front end of the connecting hole. The lower surface of the rotating shell of the handle shell has finger grooves, and the rear end of the handle shell is an open structure. This car seat adjuster handle reduces wear and extends its service life by reducing friction and dispersing forces. However, based on this disclosed technology, the handle shell is a vulnerable part, and its complex overall structure significantly increases the maintenance or replacement cost of the adjuster handle.
[0004] Therefore, the adjustment handle used in car seat adjusters needs further structural improvements to simplify its overall design. Utility Model Content

[0035] In the figure: control board 1, adapter 11, Hall bracket 2, bracket body 21, assembly 22, mounting port 23, connecting hole 24, horizontal part 211, vertical part 212, diagonal support part 213, hollow opening 28, Hall element 3, lead wire 31, sensing part 32, coil frame 4, rotor 5, pump body 6. Detailed Implementation
[0036] To make the contents of this utility model easier to understand, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings.
[0037] Example 1:
[0038] Please see Figures 1 to 4 As shown, this embodiment provides an adjustment handle, including: a handle part, a connecting piece 2, and a linkage piece 5 for use. All three can be made of metal, and overall, all three only need to adopt a thin plate structure to meet the usage requirements, so the material cost is low and it is easy to process.
[0039] Next, let's go into detail. First, the handle includes a grip 11 and a stem 12 that is bent and connected to the grip 11; the stem 12 has an oblique through hole 13. The grip 11 and the stem 12 are bent to form an obtuse angle; the obtuse angle ranges from 100° to 135°.
[0040] Secondly, there is a connecting piece 2, which has a first connecting hole and at least two second connecting holes 21. The handle 12 is rotatably engaged with the first connecting hole via a first connecting shaft 3. The first connecting shaft 3 is fixed to the connecting piece 2, and the handle 12 is rotatably sleeved on the first connecting shaft 3. In this structure, when a prying action is applied to the handle by hand, the handle can rotate around the first connecting shaft 3.
[0041] Furthermore, there is the linkage plate 5, one end of which is movably engaged with the oblong through hole 13 via a columnar connector 4; and an assembly hole is also designed on the end of the linkage plate 5 away from the columnar connector 4. In a specific optional embodiment, the linkage plate 5 adopts an oblong shape structure; the assembly hole and the columnar connector 4 are respectively located at both ends of the linkage plate 5 along its long axis. The columnar connector 4 is adapted to move along the long axis of the oblong through hole 13.
[0042] Based on the above structure, it should be noted that, in an optional implementation, the length of the handle 12 in this embodiment is greater than the length of the linkage piece 5. This design makes it easier to operate the handle with the hand.
[0043] Furthermore, it is necessary to explain that the connecting plate 2 is also provided with an L-shaped limiting piece suitable for abutting against the handle 12; the L-shaped limiting piece includes a support plate 81 fixedly connected to the connecting plate 2 and a stop plate 82 perpendicularly connected to the support plate 81; the side wall of the handle 12 facing away from the extension direction of the grip 11 is suitable for abutting against the stop plate 82. When the handle 12 abuts against the stop plate 82, the columnar connector 4 is located at the end of the waist-shaped through hole 13 facing the linkage plate 5, and the linkage plate 5 and the handle 12 form an obtuse angle on the side facing the extension direction of the grip 11, such as Figure 1 As shown.
[0044] Based on this structure, when the hand applies a gripping force to the handle, it is impossible to directly operate the adjustment handle by pressing the handle 11. This is because when the handle 11 is pressed directly and a downward force is applied to it, the handle 12 is stopped by the L-shaped limiting piece. Thus, the handle 12 cannot be directly driven to move downward under the pressing force on the handle 11, thereby preventing unintended adjustment actions caused by human error.
[0045] In summary, for the adjusting handle in this embodiment, when the hand applies an upward force to the grip 11, the grip 11 causes the handle 12 to rotate around the first connecting shaft 3, thereby releasing the handle 12 from its contact with the stop plate 82 of the L-shaped limiting plate. The columnar connector 4 moves a distance along the oblong through hole 13 away from the linkage plate 5, thus changing the initial approximately obtuse angle between the linkage plate 5 and the handle 12 to an approximately flat angle. Figure 2 As shown in the figure. At this position, you can continue to lift the handle 11 upwards. At this time, the handle 11 will drive the linkage plate 5 and the connecting plate 2 to move counterclockwise as shown in Figure 3. Alternatively, you can press the handle 11 downwards, in which case the handle 11 will drive the linkage plate 5 and the connecting plate 2 to move clockwise as shown in Figure 4.
[0046] Example 2:
[0047] Please see Figures 1 to 5 As shown, based on the adjustment handle of Embodiment 1, this embodiment provides a seat angle adjuster, including: the adjustment handle of Embodiment 1, a rotating shaft 6 connected to the mounting hole of the adjustment handle, and an adjustment disc 7 assembly connected to the rotating shaft 6; wherein the adjustment disc 7 of the adjustment disc 7 assembly is connected to at least two second connecting holes 21 of the connecting piece 2. It should be noted here that the specific implementation of the adjustment disc assembly and the rotating shaft 6 can be any mature means in the prior art, and this embodiment does not absolutely limit its specific structure and implementation principle.
[0048] Based on the above, the hand applies an upward force to the grip 11, causing the grip 11 to rotate the handle 12 around the first connecting shaft 3. This releases the handle 12 from its contact with the stop plate 82 of the L-shaped limiting plate. The columnar connector 4 moves a distance along the oblong through hole 13 away from the linkage plate 5, thereby causing the linkage plate 5 to rotate synchronously with the rotating shaft 6, changing the initial approximately obtuse angle with the handle 12 to an approximately flat angle. Figure 2As shown in the diagram. At this position, you can continue to lift the handle 11 upwards. The handle 11 will then drive the linkage plate 5 and the connecting plate 2 to move counter-clockwise as shown in diagram 3, and the adjustment disc connected to the connecting plate 2 will also move synchronously. Alternatively, you can press the handle 11 downwards. In this case, the handle 11 will drive the linkage plate 5 and the connecting plate 2 to move clockwise as shown in diagram 4, and the adjustment disc connected to the connecting plate 2 will also move synchronously.
[0049] Example 3:
[0050] Based on the seat adjuster of Embodiment 2, this embodiment provides a car seat, including: a seat frame 9, and a seat angle adjuster as described in Embodiment 2 connected to the seat frame 9. Regarding the cooperation method and principle between the seat angle adjuster and the seat frame 9, any mature means in the prior art can be used, and this embodiment does not impose an absolute limitation on this.
