Description

Technical Field

[0001] The utility model relates to the technical field of automobiles, in particular to a footrest structure used in a car. Background Art

[0002] See also Figure 1 As shown, most of the footrests on the market that are compatible with zero-gravity seats are usually arranged below the glove box 5, that is, at the installation area 6. Due to the interference between the footrest and the glove box, the space for the feet to move is limited. Moreover, the existing footrest structure usually adopts two coaxial shafts, which means that the motor can only be arranged between the two shafts. For example, in the disclosed patent CN209225024U, the driving mechanism is a motor. By arranging the motor between the two shafts to drive the two shafts to rotate at the same time, the footrest is driven to flip. In this structure, the motor will occupy the layout space of the footrest, and the footrest will be forced to move up, even higher than the floor of the car, which makes the space for the feet to move more limited. Moreover, in the case where the floor of the car is carpeted, the footrest may cause the carpet to bulge. Utility Model Content

[0007] A further improvement of the footrest structure for use in a vehicle of the utility model is that the front cover plate and the rear cover plate both include a support plate fixedly connected to the frame, a finishing layer placed on the side of the support plate away from the frame, and a support plate cover surrounding the edge of the support plate, and the edge of the finishing layer is pressed between the support plate and the support plate cover.

[0012] A further improvement of the footrest structure for use in a vehicle of the utility model is that the limiting mechanism includes a stop portion fixed to the outer periphery of the end portion of the rotating shaft, and a pair of blocking portions fixed at intervals on the corresponding side panels for blocking the stop portion, and the positions of the pair of blocking portions correspond to the first stepping position and the second stepping position respectively.

[0013] A further improvement of the footrest structure used in a vehicle of the utility model lies in that a clamping ring for blocking outside the corresponding shaft hole is clamped on the end of the rotating shaft away from the driving structure.

DETAILED DESCRIPTION

[0035] In order to solve the problem that the traditional footrest structure occupies a large space and makes the foot movement space more limited, the utility model provides a footrest structure for use in a vehicle. The footrest structure for use in a vehicle is further described below with reference to a specific embodiment and accompanying drawings.

[0036] See also Figure 2 and Figure 4As shown, a footrest structure for 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 swinging between a first stepping position and a second stepping position as the rotating shaft 2 rotates. This embodiment uses a single rotating shaft 2, so that the driving mechanism 3 can be arranged at any end of the rotating shaft 2, rather than in the middle, which reduces the arrangement space under the pedal 4, avoids excessive occupation of the foot activity space, and is more advantageous for matching with a zero-gravity seat.

[0037] As a preferred embodiment, Figure 3 , Fig.10 and Fig.11 As shown, the base 1 includes a bottom plate 11 and a left side plate 12 and a right side plate 13 respectively fixed to the left and right sides of the bottom plate 11. The left side plate 12 and the right side plate 13 are provided with a left shaft hole 121 and a right shaft hole 131 respectively. The left end 21 and the right end 22 of the rotating shaft 2 are rotatably connected to the left shaft hole 121 and the right shaft hole 131 respectively through the first torque bushing 25 and the second torque bushing 26. The driving mechanism 3 is installed on the outside of the left side plate 12 (or the right side plate 13) and connected to the left end 21 (or the right end 22) of the rotating shaft. The pedal 4 is located between the left side plate 12 and the right side plate 13. This embodiment realizes the rotation connection between the rotating shaft and the shaft hole through the torque bushing, which can ensure that there is no gap between the relative matching position of the rotating shaft and the shaft hole, and maintain a normal torque range, while solving the problem of the footrest shaking.

[0038] Preferably, in order to allow the rotating shaft 2 to be inserted into the base 1 in only one direction, the two ends of the rotating shaft 2 are designed to be one large and one small, and the corresponding two shaft holes are also one large and one small. Fig.11 As shown, in this embodiment, the diameter d2 of the right end portion 22 of the rotating shaft 2 is smaller than the diameter d1 of the left end portion 21. Accordingly, the sizes of the left shaft hole 121 and the first torque bushing 25 are both adapted to the left end portion 21, and the sizes of the shaft hole 131 and the second torque bushing 26 are both adapted to the right end portion 22. When installing the rotating shaft 2, the first torque bushing 25 is embedded in the left shaft hole 121, and the second torque bushing 26 is embedded in the right shaft hole 131, and then the rotating shaft 2 is passed through the base 1 from left to right (such as Fig.10 The right end 22 is inserted into the second torque bushing 26, and the left end 21 is inserted into the first torque bushing 25. If the shaft 2 is to be inserted into the base 1 from right to left, the above size relationship needs to be reversed. By limiting the installation method of the shaft to pass through the shaft hole in one direction, only one end of the shaft needs to be fixed, which can reduce the number of parts and reduce costs.

[0039] As a preferred embodiment, see Figure 3 , Fig.10 , Fig.14 and Fig.15 As shown, the left end portion 21 of the rotating shaft 2 passes through the left side plate 12 and is sleeved with a tooth plate 24, the driving mechanism 3 includes a motor 31 and a mounting frame 32 for mounting the motor 31 on the outer side of the left side plate 12, and a gear 312 meshing with the tooth plate 24 is sleeved on the output shaft 311 of the motor 31. Specifically, the motor 31 is fixed on the mounting frame 32, and the mounting frame 32 is mounted on the left side plate 12 by a first bolt 33. A through hole 321 for the output shaft 311 and the gear 312 to pass through is opened on the mounting frame 32. A motor shaft support 122 is also fixed at a position corresponding to the output shaft 311 on the left side plate 12, and the end of the output shaft 311 passes 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 tooth plate 24 and the left end portion 21, the end of the left end portion 21 is set as a left shaped head 21a, and the inner hole 241 of the tooth plate 24 is set as a left shaped hole adapted to the left 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 either end of the rotating shaft 2, but when the two ends are of different sizes (such as the left end portion 21 is larger than the right end portion 22 in the above embodiment), it is preferred to connect the driving mechanism 3 to the larger end portion (i.e., the left end portion 21), because the end relatively close to the driving mechanism 3 will be subjected to a greater torque than the other end.

[0040] As a preferred embodiment, a limiting mechanism is provided between at least one end of the rotating shaft 2 and the corresponding side plate to restrict the rotation range of the rotating shaft 2 so that the pedal 4 can swing between the first stepping position and the second stepping position. The limiting mechanism includes a stopper fixed to the outer periphery of the end of the rotating shaft 2, and a pair of blocking parts fixed at intervals on the outer side of the corresponding side plate to block the stopper, and the positions of the pair of blocking parts correspond to the first stepping position and the second stepping position respectively. With regard to the specific structure of the limiting mechanism, two embodiments are provided, and the two limiting mechanisms are respectively arranged on the left and right sides:

[0041] For the left limiter, refer to Fig.10 , Fig.11 and Fig.12As shown, a left stopper 29a is fixed on the left end 21 of the rotating shaft 2 and is arranged perpendicular to the axial direction of the rotating shaft. The left stopper 29a is inserted into the left end 21 and is between the first torque bushing 25 and the tooth plate 24. Through this insertion method, it can be ensured that the left stopper 29a swings synchronously with the rotation of the rotating shaft 2. The left upper blocking portion 123 and the left lower blocking portion 124 are arranged at intervals along the swinging path of the left stopper 29a on the corresponding left side plate 12. When the pedal 4 swings to the first stepping position as the rotating shaft 2 rotates clockwise, the left limit mechanism is in the state of being pressed. Fig.12 The left stopper 29a is in the state shown in the left figure, that is, the left stopper 29a just contacts the left lower blocking portion 124, thereby restricting the shaft 2 from continuing to rotate clockwise. When the pedal 4 swings to the second stepping position as the shaft 2 rotates counterclockwise, the left limit mechanism is in the state shown in the left figure. Fig.12 As shown in the right figure, the left stop portion 29a just contacts the upper left blocking portion 123, thereby restricting the rotating shaft 2 from continuing to rotate counterclockwise.

[0042] For the right side limiter, refer to Fig.10 , Fig.11 and Fig.13 As shown, the right end portion 21 of the rotating shaft 2 is provided with a right stop portion 29b perpendicular to the axial direction of the rotating shaft, and a sleeve hole 291 is provided on the right stop portion 29b, through which the right end portion 21 is sleeved. In order to ensure that the right stop portion 29b swings synchronously with the rotation of the rotating shaft 2, the end of the right end portion 21 is provided with a right special-shaped head 22a, and correspondingly, the sleeve hole 291 is provided as a right special-shaped hole adapted to the right special-shaped head 22a. Further, in order to lock the entire rotating shaft 2, a clamping ring 27 is sleeved on the outer side of the right stop portion 29b on the right end portion 21, and a clamping hole 271 is provided on the clamping ring 27, and the size of the clamping hole 271 is slightly smaller than the size of the right end portion 21, so that the clamping ring 27 can be sleeved on the right end portion 21 under the action of its own deformation, thereby achieving a locking effect. Furthermore, a washer 28 (preferably a plastic washer) is sleeved on the right end portion 21. The washer 28 is placed between the right stop portion 29b and the right side plate 12 to prevent the shaft 2 from making abnormal noises due to friction during rotation. An upper right stop portion 132 and a lower right stop portion 133 are provided 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 as the shaft 2 rotates clockwise, the right limit mechanism is in the Fig.13 The left figure shows the state, that is, the right stopper 29b just contacts the upper right blocking portion 132, thereby restricting the shaft 2 from continuing to rotate clockwise. When the pedal 4 swings to the second stepping position as the shaft 2 rotates counterclockwise, the right limit mechanism is in Fig.13 In the right figure, the right stop portion 29b just contacts the lower right blocking portion 133, thereby restricting the rotating shaft 2 to continue rotating counterclockwise.

[0043] As a preferred embodiment, Figure 5 and Figure 6 As shown, the footrest structure is arranged on the vehicle interior floor (i.e., the installation area 6 below the glove box 5), a recessed space 61 is formed on the vehicle interior floor, the base 1 is fixed in the recessed space 61, the pedal 4 is exposed from the recessed space 61 when in the first stepping position, the pedal 4 is accommodated in the recessed space 61 when in the second stepping position, and the exposed surface 47 of the pedal 4 is not higher than (as flush as possible with) the vehicle interior floor, Figure 5 and Figure 6 Both show the state when the recessed space 61 is closed. Through the coordinated setting of the recessed space, the footrest structure can be embedded below the floor of the vehicle without occupying additional installation space in the vehicle, further releasing the space for foot movement and improving the user's comfort.

[0044] As a preferred embodiment, see Figure 3 , Figures 6 to 9As shown, the pedal 4 includes a frame 41 fixedly connected to the rotating shaft 2, a front cover plate 42 and a rear cover plate 43 respectively connected to the front and back sides of the frame 41, the front cover plate 42 and the rear cover plate 43 are buckled and connected to form a cover body that completely places the frame 41 inside, and the cover body is formed with a passage 44 for the rotating shaft to pass through. Specifically, the front cover plate 42 includes a front support plate 42a fixedly connected to the frame 41, a front facing layer 42b placed on the side of the front support plate 42a away from the frame 41, and a front support plate cover 42c surrounding the edge of the front support plate 42a, the edge of the front facing layer 42b is bent 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 to the frame 41, a rear facing layer 43b disposed on the side of the rear support plate 43a away from the frame 41, and a rear support plate cover 43c surrounding the edge of the rear support plate 43a, the edge of the rear facing layer 43b is bent into an inclined surface and is pressed between the rear support plate 43a and the rear support plate cover 43c. Wherein: the front support plate 42a and the rear support plate 43a are both made of plastic, the front facing layer 42b and the rear facing layer 43b are both made of the same material as the carpet on the floor of the vehicle, the front support plate 42a and the front facing layer 42b are formed into one body by injection molding, and the rear support plate 43a and the rear facing layer 43b are formed into one body by injection molding. The front support plate 42a and the front support plate cover 42c are welded together through the front bracket 42d, and the rear support plate 43a and the rear support plate cover 43c are welded together through the rear bracket 43d. The frame 41 is connected to the front support plate 42a by a second bolt 45 and connected to the rear support plate 43a by a clamping method. The front support plate cover 42c is detachably connected to a channel cover 42e. The front support plate cover 42c, the channel cover 42e and the rear support plate cover 43c are tightly buckled to form a cover as a whole. The channel cover 42e cooperates with the rear support plate cover 43c to form the channel 44. The frame 41 is formed with a connecting ear plate 411 (such as Fig. 9 As shown), the connecting ear plate 411 is provided with a first connecting hole 412, which is matched with Fig.10 As shown, a groove 23 is formed on the rotating shaft 2 for the connecting ear plate 411 to be inserted into, and a second connecting hole 231 is opened at the bottom of the groove 23 at a position corresponding to the first connecting hole 412. The first connecting hole 412 and the second connecting hole 231 are connected in series by a third bolt 46, thereby realizing the connection between the skeleton 41 and the rotating shaft 2.

[0045] In this embodiment, the front cover plate 42 and the rear cover plate 43 of the pedal 4 are both use surfaces, and can be stepped on by feet. Figure 4As shown, when the pedal 4 is in the first stepping position, the foot steps on the front cover plate 42, and when the pedal 4 is in the second stepping position, the back of the foot steps on the rear cover plate 43. The structure of the pedal 4 changes the traditional single-sided stepping form and can achieve double-sided stepping. Furthermore, by compositely forming a finishing layer (including a front finishing layer 42b on the surface of the front cover plate 42 and a rear finishing layer 43b on the surface of the rear cover plate 43) that matches the carpet on the surface of the pedal, the appearance of the footrest matches the appearance of the floor in the car in any use state, thereby improving the aesthetics. Furthermore, by pressing the finishing layer between the support plate and the support plate cover, the edge of the finishing layer is prevented from warping.

[0046] The utility model is described in detail above in conjunction with the embodiments of the drawings. A person skilled in the art can make various variations of the utility model according to the above description.
