DETAILED DESCRIPTION

[0042] In order to solve the problem that the traditional foot support structure occupies large space and makes the foot movement space more limited, the utility model provides a foot support structure for inside a vehicle, which is further described below in combination with specific embodiments and drawings.

[0043] Referring to FIGS. 2 and 4, a foot support structure for inside a vehicle includes a base 1, a rotating shaft 2 rotatably connected to the base 1, a driving mechanism 3 mounted on the base 1 and drivingly connected to one end of the rotating shaft 2, and a pedal 4 fixedly connected to the rotating shaft 2 and pivoted between a first pedal position and a second pedal position with the rotation of the rotating shaft 2. The embodiment adopts a single rotating shaft 2, so that the driving mechanism 3 can be arranged at any one end of the rotating shaft 2 instead of being arranged at a middle position, thereby reducing the arrangement space below the pedal 4 and avoiding excessive occupation of the foot movement space, which is more beneficial to the cooperation with a zero-gravity seat.

[0044] As a preferred embodiment, as shown in FIG. 3, FIG. 10 and FIG. 11, the base 1 comprises a bottom plate 11 and left and right side plates 12 and 13 fixed to the left and right sides of the bottom plate 11 respectively, and left and right shaft holes 121 and 131 are oppositely formed in the left and right side plates 12 and 13, and the left and right end portions 21 and 22 of the rotating shaft 2 are rotatably connected to the left and right shaft holes 121 and 131 through first and second torsion bushings 25 and 26 respectively. The driving mechanism 3 is installed outside the left side plate 12 (or the right side plate 13) and connected to the left end portion 21 (or the right end portion 22) of the rotating shaft, and the pedal 4 is located between the left and right side plates 12 and 13. In this embodiment, the rotating shaft and the shaft hole are rotatably connected through the torsion bushings, which can ensure that there is no gap between the rotating shaft and the shaft hole in the relative matching position and maintain a normal torsion range, and at the same time solve the problem of the footrest shaking. Specifically, when the driving mechanism 3 drives the pedal 4 to swing over the 90-degree position or the vertical position through the rotating shaft 2, the direction of the torsion force applied to the rotating shaft 2 by the pedal 4 due to its own weight will suddenly reverse. Before the vertical position is crossed, the torsion force is a resistance force opposite to the torsion direction of the rotating shaft, and after the vertical position is crossed, the torsion force is a power force in the same direction as the torsion direction of the rotating shaft. At this time, if there is a gap between the rotating shaft and the shaft hole, the torsion force (which is a torsion power at this time) applied to the rotating shaft 2 by the pedal 4 due to its own weight will cause the pedal 4 and the rotating shaft 2 to suddenly and quickly relatively twist with respect to the shaft hole at the moment of crossing the vertical position, which causes a rigid collision between the gear 312 and the toothed plate 24 as will be described below, resulting in noise. However, the torsion bushings are provided between the rotating shaft and the shaft hole, which are designed to cooperate between the rotating shaft and the shaft hole (for example, slightly overfit) so that the shaft hole can always apply a torsion resistance to the rotating shaft through the torsion bushings, which is always opposite to the torsion direction of the rotating shaft. The torsion resistance is designed to be greater than and thus able to offset the torsion force applied to the rotating shaft by the pedal after swinging over the vertical position based on its own weight, so that the torsion resistance can prevent the rotating shaft from suddenly relatively twisting with respect to the shaft hole and prevent collision noise. However, the driving mechanism can drive the rotating shaft to twist with respect to the shaft hole to overcome the torsion resistance. The torsion bushing can include a metal base and a coating layer provided thereon for reducing friction.

[0045] Preferably, in order to make the rotating shaft 2 only inserted on the base 1 in a single direction, the two ends of the rotating shaft 2 are designed as one large and one small, and the two shaft holes are also designed as one large and one small. As shown in Figure 11, in this embodiment, the diameter d2 of the right end 22 of the rotating shaft 2 is smaller than the diameter d1 of the left end 21, and correspondingly, the size of the left shaft hole 121 and the first torsion bushing 25 are both adapted to the left end 21, while the size of the right shaft hole 131 and the second torsion bushing 26 are both adapted to the right end 22. When installing the rotating shaft 2, the first torsion bushing 25 is embedded in the left shaft hole 121, and the second torsion bushing 26 is embedded in the right shaft hole 131, then the rotating shaft 2 is inserted through the base 1 from left to right (as the view angle of Figure 10), and finally the right end 22 is inserted into the second torsion bushing 26, and the left end 21 is inserted into the first torsion bushing 25. If it is desired to make the rotating shaft 2 inserted on the base 1 from right to left, the above size relationship needs to be reversed. By limiting the installation method of the rotating shaft to pass through the shaft hole in one direction, only one end of the rotating shaft needs to be fixed, which can reduce the number of parts and reduce the cost. As can be seen from Figure 10 and especially Figure 11, the right end 22 of the rotating shaft 2 is designed as a diameter-reduced part, which has a diameter smaller than the main body diameter of the rotating shaft 2, thereby forming a step 200 between the right end 22 and the main body of the rotating shaft to the left of the right end 22. The step 200 can abut against the right side plate 13 to the right, for example, via the second torsion bushing 26, so that the axial fixation of the rotating shaft 2 to the right can be achieved through the step 200, thereby reducing the separate limiting parts of the rotating shaft.

[0046] As a preferred embodiment, referring to FIG. 3, FIG. 10, FIG. 14 and FIG. 15, the left end 21 of the rotating shaft 2 penetrates through the left side plate 12 and is sleeved with a toothed plate 24, the driving mechanism 3 includes a motor 31 and a mounting bracket 32 for mounting the motor 31 outside the left side plate 12, a gear 312 sleeved with the toothed plate 24 is arranged on the output shaft 311 of the motor 31. Specifically, the motor 31 is fixed on the mounting bracket 32, the mounting bracket 32 is mounted on the left side plate 12 through the first bolt 33, the mounting bracket 32 is provided with a through hole 321 for the output shaft 311 and the gear 312 to penetrate through, and the motor shaft support 122 is fixed on the left side plate 12 corresponding to the position of the output shaft 311, and the end of the output shaft 311 penetrates through the gear 312 and is inserted into the motor shaft support 122. The output shaft 311 is supported by the motor shaft support 122, and the rotation of the output shaft 311 is not affected. Preferably, in order to prevent relative rotation between the toothed plate 24 and the left end 21, the end of the left end 21 is provided with a left special-shaped head 21a, and the inner hole 241 of the toothed plate 24 is provided with a left special-shaped hole matched with the left special-shaped head 21a. It should be noted that when the two ends of the rotating shaft 2 are of the same size, the driving mechanism 3 can be connected to any end of the rotating shaft 2, but when the two ends are of different sizes (such as the left end 21 being larger than the right end 22 in the above embodiment), the driving mechanism 3 is preferably connected to the larger end (i.e. the left end 21), because the end closer to the driving mechanism 3 will bear a larger torque than the other end.

[0047] As a preferred embodiment, at least one end of the rotating shaft 2 and the corresponding side plate are provided with a limiting mechanism for limiting the rotation range of the rotating shaft 2, so that the pedal 4 rotates between the first pedal position and the second pedal position. The limiting mechanism includes a stop portion fixed on the outer periphery of the end of the rotating shaft 2, and a pair of blocking portions spaced apart and fixed outside the corresponding side plate to block the stop portion, and the positions of the pair of blocking portions correspond to the first pedal position and the second pedal position respectively. As to the specific structure of the limiting mechanism, two embodiments are provided, and the two limiting mechanisms are arranged on the left and right sides respectively:

[0048] With respect to the left side limiting mechanism, referring to Figs. 10, 11 and 12, the left end 21 of the rotating shaft 2 is fixed with a left stop portion 29a arranged along a direction perpendicular to the rotating shaft axial direction, the left stop portion 29a is inserted into the left end 21 and is between the first torsion bushing 25 and the tooth plate 24, through the insertion, the left stop portion 29a can be guaranteed to swing synchronously with the rotating shaft 2. Corresponding to the left side plate 12, a left upper blocking portion 123 and a left lower blocking portion 124 are arranged along the swing path of the left stop portion 29a. When the pedal 4 swings to the first pedaling position with the clockwise rotation of the rotating shaft 2, the left side limiting mechanism is in the left drawing state of Fig. 12, that is, the left stop portion 29a just abuts against the left lower blocking portion 124, so as to restrict the rotating shaft 2 to continue to rotate clockwise. When the pedal 4 swings to the second pedaling position with the counterclockwise rotation of the rotating shaft 2, the left side limiting mechanism is in the right drawing state of Fig. 12, that is, the left stop portion 29a just abuts against the left upper blocking portion 123, so as to restrict the rotating shaft 2 to continue to rotate counterclockwise.

[0049] With respect to a variant of the left side limiting mechanism, referring to Fig. 12a, the tooth plate 24 on the left end 21 of the rotating shaft 2 has a stop tooth 242 at each end. The geometric structure of the stop tooth 242 is different from the meshing tooth 243 between the two stop teeth 242 for meshing with the gear 312, for example, the former has a greater width in the circumferential direction than the latter. When the gear 312 drives the tooth plate 24, the rotating shaft 2 and thus the pedal 4 to rotate clockwise until the pedal 4 swings to the first pedaling position with the counterclockwise rotation of the gear 312, the variant of the left side limiting mechanism is in the left drawing state of Fig. 12a, that is, one meshing tooth 3121 of the gear 312 just abuts against the stop tooth 242 at the lower end and is stopped so that the gear 312 cannot continue to rotate, so as to restrict the tooth plate 24, the rotating shaft 2 and thus the pedal 4 to continue to rotate clockwise. When the gear 312 drives the tooth plate 24, the rotating shaft 2 and thus the pedal 4 to rotate counterclockwise until the pedal 4 swings to the second pedaling position with the clockwise rotation of the gear 312, the variant of the left side limiting mechanism is in the right drawing state of Fig. 12a, that is, one meshing tooth 3121 of the gear 312 just abuts against the stop tooth 242 at the upper end and is stopped so that the gear 312 cannot continue to rotate, so as to restrict the tooth plate 24, the rotating shaft 2 and thus the pedal 4 to continue to rotate counterclockwise.

[0050] In the first pedaling position and the second pedaling position, the two stop teeth 242 on the tooth plate 24 respectively have their tooth tops abutting against the tooth surface of the corresponding meshing tooth 3121 on the gear 312 to achieve stopping. In addition, in the two pedaling positions, referring to the right drawing of Fig. 12a for example, the angle between the line passing through the stop tooth 242 and the tooth plate rotation center and the line passing through the meshing tooth 3121 of the gear stopped by the stop tooth 242 and the gear rotation center is not less than 60 degrees, preferably 90 degrees, to achieve more reliable stopping.

[0051] With reference to the right limiting mechanism, as shown in FIG. 10, FIG. 11 and FIG. 13, the right end 21 of the rotating shaft 2 is provided with a right stop portion 29b arranged in a direction perpendicular to the axial direction of the rotating shaft, and a sleeve hole 291 is formed in the right stop portion 29b to be sleeved with the right end 21. In order to ensure that the right stop portion 29b swings synchronously with the rotating shaft 2, the end of the right end 21 is provided with a right special-shaped head 22a, and the sleeve hole 291 is correspondingly provided with a right special-shaped hole matched with the right special-shaped head 22a. Further, in order to lock the entire rotating shaft 2, a ring 27 is sleeved on the right end 21 outside the right stop portion 29b, and the ring 27 is provided with a clamping hole 271 with a size slightly smaller than that of the right end 21, so that the ring 27 can be sleeved on the right end 21 under the action of its own deformation, thereby achieving the locking effect. Furthermore, a gasket 28 (preferably a plastic gasket) is also sleeved on the right end 21, which is arranged between the right stop portion 29b and the right side plate 13 to prevent friction noise during the rotation of the rotating shaft 2. The right upper blocking portion 132 and the right lower blocking portion 133 are arranged on the right side plate 13 along the swing path of the right stop portion 29b. When the pedal 4 swings to the first stepping position with the clockwise rotation of the rotating shaft 2, the right limiting mechanism is in the left state of FIG. 13, that is, the right stop portion 29b just abuts against the right upper blocking portion 132, thereby restricting the rotating shaft 2 from continuing to rotate clockwise. When the pedal 4 swings to the second stepping position with the counterclockwise rotation of the rotating shaft 2, the right limiting mechanism is in the right state of FIG. 13, that is, the right stop portion 29b just abuts against the right lower blocking portion 133, thereby restricting the rotating shaft 2 from continuing to rotate counterclockwise.

[0052] As a preferred embodiment, as shown in FIG. 5 and FIG. 6, the footrest structure is arranged on the inner floor of the vehicle (i.e. the mounting area 6 below the glove box 5), and a recessed space 61 is formed on the inner floor of the vehicle, and the base 1 is fixed in the recessed space 61. The pedal 4 is exposed from the recessed space 61 in the first stepping position, and the pedal 4 is accommodated in the recessed space 61 in the second stepping position, and the exposed surface 47 of the pedal 4 is not higher than (as far as possible, flush with) the inner floor of the vehicle. FIG. 5 and FIG. 6 both show the state when the recessed space 61 is closed. Through the cooperation of the recessed space, the footrest structure can be embedded below the inner floor of the vehicle, without occupying additional installation space in the vehicle, further releasing the foot activity space, and improving the user's comfort.

[0053] As a preferred embodiment, referring to FIG. 3, FIG. 6 to FIG. 9, the pedal 4 comprises a framework 41 fixedly connected with the rotating shaft 2, a front cover plate 42 and a rear cover plate 43 respectively connected with the front face and the reverse face of the framework 41, the front cover plate 42 and the rear cover plate 43 are snap-fit connected to form a cover whole body with the framework 41 completely inside, and the cover whole body is formed with a passage 44 for the rotating shaft to pass through. Specifically, the front cover plate 42 comprises a front support plate 42a fixedly connected with the framework 41, a front veneer layer 42b disposed on the side of the front support plate 42a away from the framework 41, and a front support plate cover 42c surrounding the edge of the front support plate 42a, the edge of the front veneer layer 42b is curved into an inclined surface and is pressed between the front support plate 42a and the front support plate cover 42c. The rear cover plate 43 comprises a rear support plate 43a fixedly connected with the framework 41, a rear veneer layer 43b disposed on the side of the rear support plate 43a away from the framework 41, and a rear support plate cover 43c surrounding the edge of the rear support plate 43a, the edge of the rear veneer layer 43b is curved into an inclined surface and is pressed between the rear support plate 43a and the rear support plate cover 43c. Among them: the front support plate 42a and the rear support plate 43a are both plastic material, the front veneer layer 42b and the rear veneer layer 43b are both the same material as the carpet on the floor of the car, the front support plate 42a and the front veneer layer 42b are injection molded and combined into one, and the rear support plate 43a and the rear veneer layer 43b are injection molded and combined into one. The front support plate 42a and the front support plate cover 42c are welded together through a front support 42d, and the rear support plate 43a and the rear support plate cover 43c are welded together through a rear support 43d. The framework 41 is connected together with the front support plate 42a through a second bolt 45 and is connected together with the rear support plate 43a through a clamping method. The front support plate cover 42c is detachably connected with a passage cover plate 42e, the front support plate cover 42c, the passage cover plate 42e and the rear support plate cover 43c are tightly snap-fit to form a cover whole body, and the passage cover plate 42e cooperates with the rear support plate cover 43c to form the passage 44. The framework 41 is formed with a connecting lug plate 411 (as shown in FIG. 9) extending into the passage 44, the connecting lug plate 411 is formed with a first connecting hole 412, cooperating with FIG. 10, the rotating shaft 2 is formed with a groove 23 for the connecting lug plate 411 to be clamped into, and the groove bottom of the groove 23 is formed with a second connecting hole 231 at a position corresponding to the first connecting hole 412, the first connecting hole 412 and the second connecting hole 231 are connected through a third bolt 46, thereby realizing the connection of the framework 41 and the rotating shaft 2.

[0054] In this embodiment, both the front cover plate 42 and the rear cover plate 43 of the pedal 4 are usable surfaces, both of which can be stepped on by the foot. As shown in Figure 4, when the pedal 4 is in the second stepping position, the foot is placed on the front cover plate 42, and when the pedal 4 is in the first stepping position, the back of the foot is placed on the rear cover plate 43. This pedal 4 structure changes the traditional single-sided stepping form and can achieve double-sided stepping. Furthermore, by composite molding a trim layer adapted to the carpet on the pedal surface (including the front trim layer 42b on the surface of the front cover plate 42 and the rear trim layer 43b on the surface of the rear cover plate 43), the appearance of the footrest matches the appearance of the vehicle floor in any usage state, improving aesthetics. Furthermore, by pressing the trim layer between the support plate and the support plate cover, the edge of the trim layer is prevented from lifting. Here, when the trim layer is made of the same material as the carpet on the vehicle floor, it is difficult to achieve a continuous wrap around the entire circumference of the tray because the carpet material is hard and difficult to bend. Therefore, the trim layer is innovatively set as two separate front trim layer 42b and rear trim layer 43b that extend in a roughly planar shape respectively, and they are fixed with the tray cover.

[0055] The present invention has been described in detail above with reference to the accompanying drawings and embodiments. Those skilled in the art can make various modifications to the present invention based on the above description. Therefore, certain details in the embodiments should not be construed as limiting the present invention, and the scope of protection of the present invention shall be defined by the appended claims.
