Description

Technical Field

[0001] The utility model relates to the field of automobile seats, in particular to an automobile driver's seat extension structure. Background Art

[0002] Cars have become a necessity in people's lives. A large number of cars are purchased and used by people, which brings great convenience to people's travel. The car driver's seat is the driver's seat installed in the vehicle. It is the main sitting position for the driver when driving the car. The car driver's seat is an important connection between the driver and the vehicle. It has many designs and functions designed to provide comfort, support and safety.

[0003] However, most of the current extended structures of car driver's seats have the following problems:

[0004] For example, a car main driver's seat lifting structure with publication number CN201820630800.5 can push the seat for height adjustment through a screw rod, but the pushing force of only a single screw rod is low during adjustment. If there is someone on the seat and the seat is heavy, it is easy to cause poor pushing force, affecting the stability of use, and making it inconvenient to push the seat conveniently and stably for adjustment. At the same time, the existing car driving seat does not have the function of leg support. When the vehicle is parked aside, the driver cannot provide support for his legs when lying down to rest, which affects the comfort of rest and is inconvenient to perform convenient extension adjustment.

[0005] Therefore, we make improvements to this and propose an automobile driver's seat extension structure. Utility Model Content

[0033] Embodiment 2:

[0034] The solution in Example 1 is further introduced below in combination with a specific working method, as described below:

[0035] like Figure 3As shown, as a preferred embodiment, on the basis of the above method, further, the spring 4 is symmetrically distributed on the left and right sides of the guide block 3, and the spring 4 corresponds to the block 6 one by one through the limit plate 5, which can ensure the engagement of the block 6 on both sides, and can stably fix the use position of the guide block 3.

[0036] like Figure 3 As shown, as a preferred embodiment, on the basis of the above-mentioned method, further, the cross-section of the guide block 3 is in a "T" shape, and the side end face of the limiting plate 5 is fitted with the inner side face of the guide block 3, which can ensure that the "T"-shaped guide block 3 can slide smoothly within the driver's seat body 1.

[0037] like Figure 4 As shown, as a preferred embodiment, on the basis of the above method, further, two groups of card slots 7 are provided, and the two groups of card slots 7 are symmetrically distributed on the driver's seat body 1, and each group of card slots 7 is equidistantly distributed on the driver's seat body 1, which can ensure that the card slots 7 opened at equal angles can be adjusted and engaged according to usage.

[0038] like Figure 2 As shown, as a preferred embodiment, on the basis of the above method, further, the first bevel gear 14 is symmetrically distributed on the left and right sides of the connecting rod 12, and the first bevel gear 14 corresponds one-to-one with the threaded rod 16 through the second bevel gear 15, which can ensure that the threaded rods 16 on both sides can push the movable plate 17 to move smoothly.

[0039] like Figure 2 As shown, as a preferred embodiment, on the basis of the above-mentioned method, further, a lifting plate 18 is fixedly connected to the movable plate 17, and the lifting plate 18 is fixedly connected to the driver's seat body 1. The height of the top surface of the second bevel gear 15 is less than the height of the top surface inside the protective shell 10, which can ensure that the second bevel gear 15 can avoid the obstruction of the top surface inside the protective shell 10 and rotate smoothly when rotating.

[0040] Specifically, when the automobile driver's seat extension structure is used: Figure 1-5When adjusting the use height of the driver's seat body 1, the servo motor 11 on the protective shell 10 can be turned on, and the servo motor 11 on the protective shell 10 can be protected by the support frame 9. When the servo motor 11 drives the connecting rod 12 to rotate, the connecting rod 12 drives the connecting rods 12 on both sides to rotate simultaneously through the transmission belt 13. When the connecting rod 12 rotates, it can drive the first bevel gears 14 on both sides to rotate.

When the threaded rod 16 is controlled to operate in the opposite direction, the threaded rod 16 can drive the movable plate 17 to move downward. When the movable plate 17 moves, it can drive the driver's seat body 1 to move downward through the lifting plate 18, so as to adjust the use height of the driver's seat body 1 according to the use situation.

[0041] When the driver's seat body 1 needs to be extended and adjusted for leg support, the extrusion plates 8 on the guide blocks 3 on both sides can be squeezed, and the extrusion plates 8 drive the limit plates 5 to move. At the same time, the limit plates 5 can squeeze the springs 4 when moving, and the limit plates 5 can drive the card blocks 6 to disengage from the card slots 7 and retract them into the guide blocks 3. When the guide blocks 3 are unobstructed, the guide blocks 3 can be pushed to drive the extension support plates 2 to move. After the extension support plates 2 are pushed out of the driver's seat body 1, the driver's legs can be supported and used by using the extension support plates 2 to improve rest comfort. After the adjustment is completed, the extrusion plates 8 are released, and the limit plates 5 are driven to reset under the push of the springs 4. At the same time, the limit plates 5 can push the card blocks 6 to engage in the card slots 7, fix the use position of the extension support plates 2, and improve the stability of use.

[0042] The above embodiments are only used to illustrate the utility model but not to limit the technical solutions described in the utility model. Although the present invention has been described in detail with reference to the above embodiments, the utility model is not limited to the above specific implementation methods.
