Description

Technical Field

[0001] This utility model relates to the field of massage chair technology, specifically to an adjustment mechanism for the leg rest of a car seat. Background Technology

[0002] As people's living standards improve and automotive technology develops, people's requirements for the comfort of car seats are also increasing. Car seats have evolved from a simple component to a more complex component with higher precision requirements. Car seats and home massage chairs can easily cause fatigue for users when used for a long time.

[0003] A search revealed Chinese patent application CN120284686A, which discloses a massage mechanism for a car seat and a home massage chair, relating to the field of car massage seat technology. This invention includes an upper cover and a lower cover that engages with the upper cover. A massage head assembly is disposed between the upper and lower covers. The massage head assembly includes a massage cover with a massage ring. The massage ring has two bearings, and massage heads are mounted on the bearings. The massage heads are rotatably fitted within the massage cover. Two springs are sleeved on the outer side of the massage ring. This invention utilizes the axial positioning protrusions of the ribs on the outer side of the massage ring, which engage with the axial positioning grooves of the ribs on the inner side of the braces. While the massage head assembly revolves with the braces, it is axially positioned and can move vertically up and down, creating a composite motion trajectory of "rotation + reciprocating pressure." This reduces the limitations of airbag pushing or single mechanical rotation massage modes, enabling diverse massage techniques such as kneading and pounding.

[0004] However, existing car seat leg rests can only be adjusted to between 45 and 60 degrees, making it impossible to make them level with the seat, which reduces the comfort of users. In addition, leg rests are generally rigid, which can easily cause stiffness or pressure discomfort when the legs are rested for a long time, further reducing comfort.

[0005] The above content is only used to help understand the technical solution of this utility model and does not represent an admission that the above content is the closest prior art. Utility Model Content

[0006] This invention provides an adjustment mechanism for the leg rest of a car seat, which improves user comfort and solves the problems mentioned in the background section.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an adjustment mechanism for a car seat leg rest, comprising a main body, two connecting plates symmetrically mounted on the top of the main body, a leg rest plate provided on the side of the main body, an adjustment mechanism provided at the connection between the connecting plates and the leg rest plate, and an elastic mechanism provided inside the adjustment mechanism.

[0008] As an optional solution of this utility model, the adjustment mechanism includes a gear motor fixedly connected to the main body, a folding pusher fixedly connected to the side of the leg support plate, a rotating shaft rotatably connected to the inner side of the two connecting plates, and a gear disk fixedly connected to one end of the rotating shaft.

[0009] As an optional solution of this utility model, the telescopic end of the gear motor is fixedly connected to a rack plate, and the gear disk and the rack plate are meshed together.

[0010] As an optional solution of this utility model, a slide rail is slidably installed on the bottom of the main body, and a positioning component is installed inside the slide rail.

[0011] As an optional solution of this utility model, the elastic mechanism includes a plate body opened on the side of the leg support plate, and a mounting groove disposed in the inner cavity of the plate body, wherein a cushioning sponge is fixedly connected to the top of the mounting groove.

[0012] As an optional solution of this utility model, an elastic plate is fixedly connected to the top of the cushioning sponge, and a cushioning plate is fixedly connected to the top of the elastic plate, wherein the cushioning plate is a rubber pad.

[0013] This utility model has the following beneficial effects:

[0014] 1. The adjustment mechanism of the car seat leg rest can be set up so that the gear disk can be driven to rotate by a gear motor. With the connection of the rotating shaft and the folding push frame, the leg rest can be flipped to be horizontal with the main body, thereby increasing the comfort of the user's legs resting on the leg rest.

[0015] 2. The adjustment mechanism of the car seat leg rest, by setting an elastic mechanism, can distribute the pressure of the legs to a larger area through the slight deformation of the buffer plate after the legs are placed on the leg rest plate. This avoids the stiffness or pressure that can easily occur when the legs are placed on the seat for a long time due to rigid support, thus improving the user's comfort. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example:

[0025] Please see Figure 1-3 An adjustment mechanism for a car seat leg rest includes a main body 1. Two connecting plates 2 are symmetrically mounted on the top of the main body 1, and a leg rest plate 3 is provided on the side of the main body 1. An adjustment mechanism 4 is provided at the connection between the connecting plates 2 and the leg rest plate 3, and an elastic mechanism 5 is provided inside the adjustment mechanism 4. By setting the adjustment mechanism 4, the leg rest plate 3 can be flipped to be horizontal with the main body 1, thereby increasing the comfort of the user's legs resting on the leg rest plate 3. By setting the elastic mechanism 5, the pressure of the legs can be distributed to a larger area after resting the legs on the leg rest plate 3, avoiding the stiffness or pressure caused by rigid support after a long time, thus improving the user's comfort.

[0026] Furthermore, the adjustment mechanism 4 includes a gear motor 41 fixedly connected to the main body 1, a folding pusher 42 fixedly connected to the side of the leg support plate 3, a rotating shaft 44 rotatably connected to the inner side of the two connecting plates 2, and a gear disk 43 fixedly connected to one end of the rotating shaft 44; a rack plate fixedly connected to the telescopic end of the gear motor 41, and the gear disk 43 and the rack plate meshing with each other; a slide rail 45 is slidably installed at the bottom of the main body 1, and a positioning component 46 is installed inside the slide rail 45.

[0027] Specifically, by turning on the gear motor 41, it moves closer to the leg rest 3. With the connection of the rack plate, the gear disk 43 can rotate, which in turn drives the rotating shaft 44 to rotate. With the connection of the folding push frame 42, the leg rest 3 can rotate until it flips to be horizontal with the main body 1, thereby increasing the comfort of the user's legs resting on the leg rest 3. By setting the slide rail 45 and the positioning member 46, the main body 1 can be moved back and forth.

[0028] Preferably, the elastic mechanism 5 includes a plate 51 formed on the side of the leg support plate 3, and a mounting groove 52 provided in the inner cavity of the plate 51. A cushioning sponge 53 is fixedly connected to the top of the mounting groove 52, an elastic plate 54 is fixedly connected to the top of the cushioning sponge 53, and a cushioning plate 55 is fixedly connected to the top of the elastic plate 54. The cushioning plate 55 is a rubber pad.

[0029] Specifically, when the legs are placed on the leg support plate 3, the deformation of the cushioning plate 55 can distribute the pressure on the legs to a larger area. When the user sits up and the center of the body shifts towards the legs, the pressure on the cushioning plate 55 increases. At this time, the cushioning plate 55 applies pressure to the elastic plate 54, which in turn causes the cushioning sponge 53 to be compressed within the plate 51, further dispersing the pressure, reducing the squeezing of the legs, and increasing the comfort of the legs.

[0031] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
