[0051] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0052] Embodiments of the present invention will now be described in detail with reference to the accompanying drawings. Reference will now be made in detail to preferred embodiments of the present invention, examples of which are shown in the accompanying drawings. Wherever possible, the same reference numerals will be used throughout the drawings to represent the same or similar parts.

[0053] Furthermore, although the terms used in the present invention are selected from well-known and commonly used terms, some terms mentioned in the present invention specification may be selected by the applicant at his or her discretion, and their detailed meanings are explained in the relevant parts of the description of this document.

[0054] Furthermore, it is required that the present invention be understood not only by the actual terms used but also by the meanings connoted by each term.

[0055] like Figures 1 to 3 As shown, the present invention discloses an invisible foot pad for a seat, which comprises: a base 10, a connecting rod seat 20, at least two groups of connecting rod assemblies 30 arranged in parallel with each other, a pedal assembly 40 and a folding pull rod driving mechanism 50. The connecting rod seat 20 is installed at the lower end of the base 10. Each group of connecting rod assemblies 30 comprises at least two connecting rods 31 rotatably connected to each other, and the first ends of the two groups of connecting rod assemblies 30 are respectively installed with first synchronous gears 32 meshing with each other, and the first ends are rotatably connected to the connecting rod seat 20.

[0056] The second ends of the two groups of connecting rod assemblies 30 are respectively installed with second synchronous gears 33 meshing with each other, and the second ends are rotatably connected to the pedal assembly 40. The folding rod driving mechanism 50 is installed on the connecting rod seat 20, and the driving part of the folding rod driving mechanism 50 is connected to one group of connecting rod assemblies 30. The corresponding connecting rod assembly 30 is pulled by the folding rod driving mechanism 50, and the rotation of the first synchronous gear 32 and the second synchronous gear 33 drives the connecting rod assembly 30 to synchronously retract inward or extend outward.

[0057] The meshing arrangement of the first synchronous gear 32 and the second synchronous gear 33 can ensure that the two sets of connecting rod assemblies 30 can achieve synchronous movement when they shrink inward or extend outward, and are located in the same plane, and the movement is smooth and stable. The connecting rod arrangement of the two pairs of synchronous gears enables the folding mechanism to achieve a large-stroke telescopic movement.

[0058] Preferably, each connecting rod 31 includes at least two connecting rod portions 311 rotatably connected to each other. For example, the adjacent ends of the two connecting rod portions 311 are rotatably connected via a rotating shaft 312 (eg, Figure 5 Then, the two adjacent ends of the two connecting rods 31 are also connected by rotation through the rotating shaft. This embodiment adopts this rotation structure. When the connecting rod assembly 30 is in the folded and contracted state and touches the ground, the connecting rod part located on the outside is bent upward relative to the connecting rod part 311 located on the inside.

[0059] like Figure 4 As shown, the folding rod driving mechanism 50 includes a screw motor 51 and a motor mounting seat 52. The screw motor 51 is mounted on the motor mounting seat 52, and the motor mounting seat 52 is fixed on the connecting rod seat 20, and the screw 53 of the screw motor 51 is connected to the corresponding connecting rod assembly 30. The screw motor 51 includes a worm gear 54 and a worm (i.e., the screw 53), and drives the screw 53 to pull or push the corresponding connecting rod assembly 30, thereby driving the first synchronous gear 32 and the second synchronous gear 33 to rotate, so that the two groups of connecting rod assemblies 30 can be retracted inwardly and extended outwardly, so that the folding, retracting and extending functions of the foot pad can be realized.

[0060] like Figures 1 to 3 As shown, further preferably, the invisible foot pad of the seat in the present application may also include a slide 60 and a stretching rod driving mechanism 70, and the stretching rod driving mechanism 70 is installed on the slide 60. At least one slide groove 11 (for example Figure 2 Two waist-shaped grooves are provided in the middle. At least one sliding member (such as a pin 61) protruding outward is installed on the outer wall surfaces of both sides of the slide seat 60, and the sliding member is installed in the slide groove 11. The driving part of the stretching rod driving mechanism 70 is connected to the connecting rod seat, and the slide seat 60 is driven to move up and down along the base 10 through the sliding member, thereby driving the connecting rod seat 20 to move up and down (such as Fig. 9 and Fig.10 as shown).

[0061] Preferably, the structure of the stretching rod driving mechanism 70 in this embodiment is consistent with the structure of the folding rod driving mechanism 50. The stretching rod driving mechanism 70 includes a screw motor 71 and a motor mounting seat 72, the screw motor 71 is mounted on the motor mounting seat 72, the motor mounting seat 72 is fixed on the slide 60, and the screw of the screw motor 71 is connected to the connecting rod seat 20.

[0062] Here, the setting of the stretch rod driving mechanism 70 can realize the lifting action of the foot pad, and the screw motor 71 drives the screw to pull the connecting seat 20, so that the slide seat 60 slides up and down along the two side walls of the base 10. Since the connecting seat 20 and the base 10 are rotatably connected through the rotating shaft, the connecting seat 20 drives the connecting rod assembly 30 to be lifted upward. In this way, the foot pad can be lifted as a whole at a certain angle (such as Fig. 9 and Fig.10 as shown).

[0063] By stretching the screw motor 71 of the pull rod driving mechanism 70, the foot pad can be lifted to adapt to the use of people of different heights. For example, when the seat anti-roll mechanism is working, the foot pad of the entire seat can be raised by a certain distance A, about 30 mm (e.g. Fig.21The connecting seat 20 drives the connecting rod assembly 30 to lift up at an angle β of about 10° (as shown in FIG. Fig.19 as shown).

[0064] More preferably, if Figure 2 As shown, the base 10 and the slide 60 are both configured as an open "concave" structure, for example, formed by bending a plate-like structure. The motor mounting seat 72 is fixed in the slide 60, and the screw motor 71 is inserted into the side of the base 10 and the slide 60 and fixed to the motor mounting seat 72.

[0065] The pedal assembly 40 includes a pedal seat 41, a pedal connecting seat 42 and two pedals 43. The pedal connecting seat 42 is installed on the pedal seat 41. The pedal seat 41 is rotatably connected to the second end of the connecting rod assembly 30 through the pedal connecting seat 42. The pedals 43 are rotatably connected to both sides of the pedal seat 41.

[0066] In addition, if Figure 2 As shown, a pedal soft bag 44 may be wrapped on the outside of the pedal assembly 40 , which may improve the aesthetics of the pedal assembly 40 on the one hand, and protect the pedal assembly 40 and mitigate the impact on the pedal assembly 40 on the other hand.

[0067] like Figure 7 and Figure 8 As shown, the pedal 43 can be rotatably connected to both sides of the pedal seat 41 through a rotating shaft, and when the seat rolls, the pedal 43 is allowed to touch the ground. Once the pedal 43 touches the ground, the pedal 43 is free to bend around the rotating shaft and lift up. For example, the maximum allowable bend angle α is 20° (such as Figure 8 As shown), the pedal 43 is prevented from rubbing against the ground and damage is reduced.

[0068] In addition, the seat invisible foot pad also includes a pedal airbag 80, and the pedal airbag 80 is installed at the bottom of the pedal seat 41. Fig. 20 As shown, when the pedal airbag 80 is not inflated, the seat invisible foot pad extends forward horizontally. Fig.21 As shown, when the pedal airbag 80 is inflated, it pushes the pedal assembly 40 upward, so that the pedal assembly 40 is lifted upward by a certain angle, further improving the comfort of the occupant.

[0069] like Fig.11 and Fig.12 As shown, when the invisible seat foot pad is needed, the folding pull rod driving mechanism 50 pushes the connecting rod assembly 30 in the folded state, and the first synchronous gear 32 and the second synchronous gear 33 start to rotate, thereby driving the connecting rod assembly 30 to extend forward synchronously until it is fully unfolded (as shown in FIG. Fig.13 and Fig.14 At this time, the passenger can place his feet on the foot pad to improve riding comfort.

[0070] Fig.15 and Fig.16 As shown, when the invisible seat foot pad is not needed, the folding rod driving mechanism 50 pulls the connecting rod assembly 30 in the extended state, and the first synchronous gear 32 and the second synchronous gear 33 start to rotate, thereby driving the connecting rod assembly 30 to fold inward synchronously until it is completely folded (as shown in FIG. Fig.15 and Fig.16 At this time, the invisible foot pad can be hidden at the bottom of the seat, adapting to various types of seats for use in narrow spaces and meeting the diverse riding needs of passengers.

[0071] like Figures 17 to 21 As shown, the present invention further provides a sway-resistant seat, which comprises the invisible seat foot pad 100 as described above, and the base 10 of the invisible seat foot pad 100 is fixed to the lower end of the sway-resistant seat.

[0072] In summary, the invisible seat foot pad of the present invention and the anti-roll seat of the automobile including the invisible seat foot pad have the following advantages:

[0073] 1. Two pairs of synchronous gear connecting rods are used to form a folding mechanism to achieve a large-stroke telescopic movement, so that the foot pad can be hidden under the seat and adapt to a small space;

[0074] 2. Use a screw motor to achieve the lifting action of the foot pad to match people of different heights.

[0075] 3. The extremely small thickness space under the seat is utilized so that the passenger's feet can move with the seat, making the ride more comfortable.
