Description

Technical Field

[0001] The utility model relates to the technical field of automobile seats, in particular to an automobile seat with a thigh support adjustment function. Background Art

[0002] As cars enter thousands of households, cars have become a necessity in people's daily lives, and people's requirements for the comfort of cars are increasing. Traditional car seats do not have a leg rest design and cannot adapt to drivers and passengers of different heights. Generally speaking, in order to adapt to petite drivers and passengers, the common practice is to design the seat pan to be relatively short. Therefore, for tall drivers and passengers, such seats obviously cannot meet the comfort requirements. Therefore, a car seat with an adjustable seat pan length and a car seat with a calf leg rest have emerged on the market. Among them, the existing car seat with a calf leg rest cannot be used for the driving position. The existing car seats with adjustable seat length are usually adjusted manually, which not only cannot meet the requirements of automation, but also the seat cover of the seat is usually in a loose state when the seat is in the storage state to meet the requirements of seat length adjustment. The disadvantage of this design is that when the seat is restored from the extended state to the storage state, the seat cover is loose and cannot effectively support the thighs of the driver and passenger, which is very likely to pinch the flesh of the thighs of the driver and passenger, resulting in poor safety. In addition, after the seat of the existing car seat is extended, its front end is relatively thin, which not only cannot provide effective support for the position between the thigh and the calf, but also leads to poor comfort. Solving the above problems has become a top priority.

[0003] In order to solve the above technical problems, the Chinese invention patent with the authorization announcement number CN107499211B discloses a thigh leg support adjustment mechanism and a car seat basin with the mechanism. The invention patent has a novel structure, is easy to implement, adopts an electric adjustment method, is easy to operate, and has precise adjustment. It can provide effective support for the thigh and the position between the thigh and the calf, has good comfort and high safety.

[0004] Although the technical solution provided by this invention patent solves the problem that the existing thigh leg rest may pinch the passenger when in use, the mechanism for driving the outer panel of the leg rest to flip in the above solution is relatively complicated, which is inconvenient to assemble during the production process and will also increase the cost.

[0023] The technical solutions provided by various embodiments of the present application are described in detail below in conjunction with the accompanying drawings.

[0024] See also Figure 1-4 , a car seat with a thigh leg support adjustment function; comprising a seat basin 4, the seat basin 4 is fixedly installed in the car interior by bolts 5, the upper surface of the seat basin 4 is slidably connected with a seat plate 1, one end of the seat plate 1 is hinged with a flippable leg support plate 3 through a connecting shaft 2, and the lower surface of the seat basin 4 is provided with a driving mechanism for driving the leg support plate 3 to flip;

[0025] When the seat plate 1 slides forward, the leg support plate 3 can be turned upward under the action of the tension of the seat cover, and when the seat plate 1 is retracted backward, the leg support plate 3 can be driven to turn downward under the action of the driving mechanism;

[0026] The driving mechanism comprises two mirror-imaged special-shaped arms 13, which are hinged to the lower surface of the seat plate 1 through a rotating shaft 14, and the two special-shaped arms 13 are fixedly connected to a driving rod 16 at the opposite ends thereof, and a connecting ear plate 17 is integrally formed on the leg support plate 3, and the driving rod 16 is slidably arranged in a through hole provided on the connecting ear plate 17;

[0027] A drive motor 6 is also fixedly mounted on the lower surface of the seat basin 4. A mounting seat 7 is also fixedly mounted on the lower surface of the seat basin 4. A worm gear screw moving mechanism is installed inside the mounting seat 7. The worm gear screw moving mechanism includes a worm wheel, a worm and a screw 8. The worm gear screw moving mechanism is a prior art, and the connection relationship and working principle of its internal mechanism are no longer described in detail. The output shaft of the drive motor 6 is fixedly connected to the end of the worm so that the screw 8 is used to drive the seat plate 1 to slide forward and backward. The seat plate 1 can be driven to slide forward or backward through the coordinated arrangement between the drive motor 6 and the worm gear screw moving mechanism.

[0028] Guide vertical plates 10 are provided on both sides of the lower surface of the seat plate 1, and guide slide grooves 11 are formed on both sides of the upper surface of the seat basin 4. The guide vertical plates 10 are slidably installed inside the guide slide grooves 11. The coordination between the guide vertical plates 10 and the guide slide grooves 11 can improve the stability of the seat plate 1 during the sliding process;

[0029] A connecting plate 12 is fixedly connected to the middle of one end of the seat plate 1 facing the leg support plate 3, and a connecting member 9 is integrally formed in the middle of the connecting plate 12. The connecting member 9 is fixedly connected to the end of the screw 8 through a lock buckle;

[0030] The rotating shaft 14 is fixedly installed in the middle of the special-shaped arm 13, and two fixed plates 15 are fixedly connected to the lower surface of the seat basin 4. The opposite ends of the two special-shaped arms 13 are respectively abutted against one side of the two fixed plates 15. By providing the fixed plates 15, one end of the special-shaped arm 13 can be limited and blocked when the seat plate 1 slides backward, so that the other end of the special-shaped arm 13 can drive the leg support plate 3 to flip downward, thereby realizing the storage of the leg support plate 3;

[0031] When the utility model is in use, the driving motor 6 is first started, and the driving motor 6 can drive the worm gear screw moving mechanism to transmit, thereby making the screw 8 move forward or backward, and the screw 8 can move forward to drive the connecting upright plate 12, the seat plate 1 and the leg support plate 3 to move forward through the connecting member 9, so that the seat plate 1 can slide out to the range of the seat basin 4. When the seat plate 1 moves forward and slides out of the seat basin 4, the tension of the seat cover covering the seat plate 1 and the seat basin 4 is continuously increased. Therefore, the seat cover has the force to pull the leg support plate 3 upward. The leg support plate 3 will flip upward at a certain angle under the pulling of the seat cover, so that the thighs and legs of the passengers can be effectively supported, and the comfort is improved;

[0032] When the leg support plate 3 needs to be flipped downward, the driving motor 6 is controlled to reverse, which can drive the worm gear screw moving mechanism to transmit, thereby making the screw 8 move backward, and the screw 8 and the connecting member 9 can drive the connecting vertical plate 12, the seat plate 1 and the special-shaped arm 13 to move backward, and the special-shaped arm 13 gradually moves backward, and the special-shaped arm 13 will gradually approach the fixed plate 15, and the fixed plate 15 blocks one end of the special-shaped arm 13, so that the other end of the special-shaped arm 13 can drive the leg support plate 3 to flip downward through the driving rod 16, and through the above series of steps, the leg support plate 3 can be driven to flip downward while the seat plate 1 moves backward, so that the seat cover can be restored to its original shape;

[0033] The seat cover has a certain degree of ductility and elasticity. No matter when the seat board 1 slides forward or slides in backward, the seat cover is in a taut state. The seat cover not only provides continuous and effective support for the thighs of the driver and occupants to prevent flesh pinching and has high safety, but also the seat cover can pull the leg support plate 3 upward by its own tension when the seat board 1 slides forward, so that it flips upward and is in an open state, thereby enabling the leg support plate 3 to provide effective and comfortable support for the thighs of the driver and occupants and the joints between the thighs and calves; when the seat board 1 slides backward, the tension of the seat cover begins to decrease, and at the same time, through the lever relationship formed between the special-shaped arm 13 and the fixed plate 15, the leg support plate 3 can be flipped downward while the seat board 1 moves backward, thereby realizing the storage of the leg support plate 3.

[0034] The above is only an embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various changes and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application should be included in the scope of the claims of the present application.
