DETAILED DESCRIPTION

[0025] In order to make the above objectives, characteristics and advantages of the present application more obvious and easy to understand, the specific embodiments of the present application are described in detail below with reference to the drawings.

[0026] In the description of the present application, unless otherwise explicitly specified and limited, the terms "mounting", "connection", "connecting", "fitting" should be understood in a broad sense, for example, can be fixed connection, can also be detachable connection, or integrally connected; can be directly connected, or indirectly connected through an intermediate medium; can be the communication inside two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0027] In addition, it should be noted that in the description of the present application, it should be noted that the terms such as "upper", "lower", "front", "rear" and other words indicating the position in each embodiment only indicate the positional relationship based on the drawings of the specification, and do not represent that the elements and devices referred to must be operated according to the specific position and limited operation and method, structure in the specification, and such positional terms do not constitute a limitation on the present application.

[0028] A coordinate system XYZ is established herein, the direction represented by the X axis represents the front-rear direction of the automobile, wherein the positive direction of the X axis represents the front of the automobile, and the negative direction of the X axis represents the rear of the automobile, the direction represented by the Y axis represents the left-right direction of the automobile, wherein the positive direction of the Y axis represents the left of the automobile, and the negative direction of the Y axis represents the right of the automobile, the direction represented by the Z axis represents the up-down direction of the automobile, wherein the positive direction of the Z axis represents the upper of the automobile, and the negative direction of the Z axis represents the lower of the automobile.

[0029] As shown in FIG. 1, the automobile carpet 6 is arranged on the mounting base 3, and the mounting base 3 is arranged on the pedal body 1. Figures 1-2As shown, the embodiment of the present application provides a foot rest, which comprises a foot plate body 1, lifting rods 2 and a mounting base 3. The lifting rods 2 are at least two, which are used to lift the same or different height simultaneously or respectively. The two ends of the lifting rods 2 are connected with the mounting base 3 and the foot plate body 1 respectively, so that the foot plate body 1 is lifted relative to the mounting base 3.

[0030] Specifically, the foot plate body 1 can be a cuboid structure, which extends along the direction of the automobile width direction, i.e. the direction of the Y axis, for placing the feet of the driver and the passenger. The lifting rods 2 are vertically lifted, which can be automatically lifted or manually lifted, such as the lifting mode of umbrella skeleton. The lifting rods 2 can be two, three or more. When the lifting rods 2 are two, the two lifting rods 2 can be arranged along the front-rear direction of the automobile or along the left-right direction of the automobile. When the lifting rods 2 are three, the three lifting rods 2 can be arranged on a straight line or in a triangular shape.

[0031] In the embodiment, the mounting base 3 can be mounted on the metal part at the bottom of the automobile. The foot plate body 1 is connected with the mounting base 3 through the at least two lifting rods 2. Exemplarily, the lifting rods 2 can be two or three. By lifting all the lifting rods 2 simultaneously or respectively to the same height, the supporting height of the foot plate body 1 can be adjusted. By lowering all the lifting rods 2 simultaneously or respectively to the same height, the supporting height of the foot plate body 1 can be adjusted. By lifting or lowering all the lifting rods 2 to different heights, the supporting angle of the foot plate body 1 can be adjusted. Exemplarily, when the lifting rods 2 are two along the front-rear direction or the width direction of the automobile, the two lifting rods 2 are lifted or lowered to different heights, so that the inclination angle of the foot plate body 1 along the front-rear direction or the width direction of the automobile can be adjusted. When the lifting rods 2 are three or other number, the adjustment is similar. In this way, the use of different height legs of the personnel is satisfied, and the use comfort is better.

[0032] As shown, Figure 2 Optionally, the lifting rods 2 are three and arranged in a triangular shape. The three lifting rods 2 are a first lifting rod 21, a second lifting rod 22 and a third lifting rod 23. The first lifting rod 21 is located at the position of the mounting base 3 close to the front of the automobile. The second lifting rod 22 and the third lifting rod 23 are located at the positions of the mounting base 3 close to the rear of the automobile.

[0033] Specifically, the three lifting rods 2 can be arranged in an isosceles triangle, wherein the first lifting rod 21 is located at the top corner of the isosceles triangle, and the second lifting rod 22 and the third lifting rod 23 are located at the two bottom corners of the isosceles triangle. The mounting base 3 extends in the front-rear direction. The front end of the pedal body 1 is connected to the front end of the mounting base 3 through the first lifting rod 21. The left side of the rear end of the pedal body 1 is connected to the left side of the rear end of the mounting base 3 through the second lifting rod 22. The right side of the rear end of the pedal body 1 is connected to the right side of the rear end of the mounting base 3 through the third lifting rod 23.

[0034] In the embodiment, the three lifting rods 2 arranged in a triangle have better support stability for the pedal body 1. When a driver places his feet on the pedal body 1, the gravity of the driver is mainly concentrated on the heels, and the force applied by the toes to the pedal body 1 is small. Therefore, two lifting rods 2 are arranged at the left and right sides of the rear end of the pedal body 1, and one lifting rod 2 is arranged at the front end of the pedal body 1. Here, the three lifting rods 2 can be driven by three driving assemblies respectively, or can be driven by two driving assemblies, wherein one driving assembly controls the lifting of the two lifting rods 2, thereby saving the number of driving assemblies and simplifying the structure.

[0035] As shown in Figure 3 Optionally, the first driving assembly 4 is further included. The first driving assembly 4 includes a first rotary driving motor 41 and a first rotary-to-linear motion conversion mechanism 42. The first rotary driving motor 41 is mounted on the mounting base 3. The first rotary driving motor 41 is drivingly connected to the first lifting rod 21 through the first rotary-to-linear motion conversion mechanism 42.

[0036] Specifically, the first lifting rod 21 at the front end is connected to the first driving assembly 4. The first driving assembly 4 can drive the first lifting rod 21 to vertically lift. The first rotary driving motor 41 can be fixed to the bottom of the mounting base 3. One end of the first rotary-to-linear motion conversion mechanism 42 is connected to the output end of the first rotary driving motor 41. The other end of the first rotary-to-linear motion conversion mechanism 42 penetrates through the mounting base 3 to be connected to the first lifting rod 21.

[0037] In the embodiment, the first rotary driving motor 41 provides a driving force for rotating around the Z-axis. The first rotary-to-linear motion conversion mechanism 42 can convert the rotary driving force around the Z-axis into a linear driving force around the Z-axis to drive the first lifting rod 21 to lift in the vertical direction, i.e., in the direction shown by the Z-axis.

[0038] As shown in Figure 3As shown, optionally, the first rotary-to-linear motion mechanism 42 includes a first worm 421, a first worm wheel 422, and a first rack 423. The first worm 421 is connected to the first rotary drive motor 41, the first rack 423 is vertically arranged on the lifting rod 2, and the first worm wheel 422 is located between the first worm 421 and the first rack 423, and meshes with the first worm 421 and the first rack 423 respectively for transmission.

[0039] Specifically, the first worm gear 421 is vertically arranged and located on one side of the first lifting rod 21. The first lifting rod 21 is provided with the first rack 423 on the side near the first worm gear 421. The first rack 423 can be integrally formed with the lifting rod 2. The axis of the first worm wheel 422 is along the Y-axis.

[0040] In this embodiment, the first rotary drive motor 41 rotates to drive the first worm gear 421 to rotate around the Z-axis. The first worm gear 421 drives the first worm wheel 422 to rotate around the Y-axis. The first worm wheel 422 then drives the first rack 423 to move together with the first lifting rod 21 along the Z-axis. When the first rotary drive motor 41 rotates in the forward direction, the first worm gear 421 and the first worm wheel 422 rotate in the forward direction, and the first rack 423 and the first lifting rod 21 rise. Correspondingly, when the first rotary drive motor 41 rotates in the reverse direction, the first lifting rod 21 descends. A through hole can be provided on the mounting base 3 at the position corresponding to the first lifting rod 21, so that the first lifting rod 21 can pass through the through hole to rise and fall smoothly.

[0041] Of course, in some other embodiments, the first rotary linear motion mechanism 42 can be a lead screw transmission mechanism, which includes a lead screw, a slider and a slide groove. The slide groove is vertically fixed on the mounting base 3, the slider is fixed on the first lifting rod 21, the slider is sleeved on the lead screw, the slider is located in the slide groove, the lead screw is connected to the first rotary drive motor 41, the first rotary drive motor 41 drives the lead screw to rotate, so as to drive the slider to move vertically along the slide groove, thereby driving the first lifting rod 21 to rise and fall.

[0042] In some other embodiments, the first rotation-to-linear motion mechanism 42 may include a threaded rod, one end of which is connected to the first rotary drive motor 41, and the other end of which is threaded to the first lifting rod 21, thereby converting the driving force of the first rotary drive motor 41 rotating around the Z-axis into a linear feed driving force along the Z-axis, driving the first lifting rod 21 to rise and fall.

[0043] like Figure 4Optionally, the second driving assembly 5 is further included, the second driving assembly 5 comprising a second rotary driving motor 51, a swing mechanism, a second rotary-to-linear motion conversion mechanism 52 and a third rotary-to-linear motion conversion mechanism 53, the swing mechanism comprising a driving disc 54 and two swing gears 55 connected to both sides of the driving disc 54 respectively, the second rotary driving motor 51 being drivingly connected to the driving disc 54, one of the swing gears 55 being connected to the second lifting rod 22 through the second rotary-to-linear motion conversion mechanism 52, and the other swing gear 55 being connected to the third lifting rod 23 through the third rotary-to-linear motion conversion mechanism 53.

[0044] In the embodiment, the second lifting rod 22 and the third lifting rod 23 at the rear end are connected to the second driving assembly 5, and the second driving assembly 5 can drive the second lifting rod 22 and the third lifting rod 23 to simultaneously lift or lower by the same height. It is mainly considered that a person generally has a demand for tilting in the front-rear direction when placing the feet, and the left and right sides of the feet are at the same height. At this time, only the first driving assembly 4 can be started to lift or lower the front end of the pedal body 1, or the second driving assembly 5 can be started to lift or lower the rear end of the pedal body 1. Of course, in some embodiments, the second driving assembly 5 can also drive the second lifting rod 22 and the third lifting rod 23 to respectively lift or lower by the same or different heights for users with special needs.

[0045] The central axis of the driving disc 54 is along the direction shown by the Z axis, the center of the driving disc 54 is connected to the second rotary driving motor 51, one swing gear 55 is arranged on each of the upper and lower sides of the driving disc 54, and the driving disc 54 drives the two swing gears 55 to horizontally rotate in the process of horizontal rotation, so as to respectively transmit to the second rotary-to-linear motion conversion mechanism 52 and the third rotary-to-linear motion conversion mechanism 53. The second rotary-to-linear motion conversion mechanism 52 converts the rotary driving force around the Z axis into the linear driving force around the Z axis, so as to drive the second lifting rod 22 to vertically lift or lower. Meanwhile, the third rotary-to-linear motion conversion mechanism 53 converts the rotary driving force around the Z axis into the linear driving force around the Z axis, so as to drive the third lifting rod 23 to vertically lift or lower.

[0046] It should be noted that when the second rotary driving motor 51 rotates forward, the driving disc 54 and the swing gears 55 rotate forward, and the second lifting rod 22 and the third lifting rod 23 rise. When the second rotary driving motor 51 reversely rotates, the driving disc 54 and the swing gears 55 reversely rotate, and the second lifting rod 22 and the third lifting rod 23 lower. The lifting of the second lifting rod 22 and the third lifting rod 23 is controlled by the second rotary driving motor 51. Compared with the mode that one motor controls one lifting rod, the number of motors is reduced, and the structure design is simplified.

[0047] As shown in FIG. 1, the pedal body 1 comprises a pedal body 10, a pedal body 11, a pedal body 12, a pedal body 13, a pedal body 14 and a pedal body 15. Figures 4-6As shown, optionally, two of the swing gears 55 are symmetrically arranged about the driving disc 54, one end of the swing gear 55 is rotationally connected with the mounting base 3, the other end of the swing gear 55 is provided with a gear portion 551 to be connected with the second rotation-to-linear motion mechanism 52 or the third rotation-to-linear motion mechanism 53, the middle part of the swing gear 55 is provided with a limiting post 552, and the two sides of the driving disc 54 are respectively provided with variable-diameter limiting grooves 541 in the circumferential direction, the limiting post 552 of the two swing gears 55 is respectively inserted into the corresponding variable-diameter limiting groove 541, when the driving disc 54 rotates, the limiting post 552 moves relative to the variable-diameter limiting groove 541, and the swing gear 55 rotates about the rotation connection point of the swing gear 55 and the mounting base 3.

[0048] Specifically, the two swing gears 55 are centrally symmetric about the driving disc 54, one of the swing gears 55 is located at the position on the upper side of the driving disc 54 and towards the front end of the automobile, and the other swing gear 55 is located at the position on the lower side of the driving disc 54 and towards the rear end of the automobile, the upper and lower sides of the driving disc 54 are respectively provided with variable-diameter limiting grooves 541, the variable-diameter limiting groove 541 is an arc-shaped limiting groove, that is, the distance from each part of the variable-diameter limiting groove 541 to the center of the driving disc 54 is not equal along the extension direction of the limiting groove, or the radius gradually decreases or increases in the direction from one end of the variable-diameter limiting groove 541 to the other end of the variable-diameter limiting groove 541, the faster the variable-diameter limiting groove 541 changes in the radial direction, the faster the swing gear 55 swings, and the faster the lifting rod lifts, and vice versa.

[0049] In this embodiment, when the second rotation driving motor 51 drives the driving disc 54 to rotate about the Z axis, the groove wall of the variable-diameter limiting groove 541 pushes the limiting post 552 to slide along the variable-diameter limiting groove 541, the movement of the limiting post 552 drives the swing gear 55 to rotate about the rotation connection point of the swing gear 55 and the mounting base 3, and the gear portion 551 at one end of the swing gear 55 transmits the rotation driving force to the second rotation-to-linear motion mechanism 52 or the third rotation-to-linear motion mechanism 53 to drive the corresponding lifting rod to lift.

[0050] As shown, the two lifting rods 56 are respectively connected with the second rotation-to-linear motion mechanism 52 or the third rotation-to-linear motion mechanism 53, the second rotation-to-linear motion mechanism 52 or the third rotation-to-linear motion mechanism 53 is connected with the swing gear 55, and the swing gear 55 is rotationally connected with the mounting base 3. Figures 5-6As shown, optionally, two sides of the driving disc 54 are respectively provided with an equal-diameter limiting groove 542 communicated with the corresponding variable-diameter limiting groove 541, the variable-diameter limiting groove 541 on one side of the driving disc 54 is correspondingly arranged with the variable-diameter limiting groove 541 on the other side of the driving disc 54, the equal-diameter limiting groove 542 on one side of the driving disc 54 is correspondingly arranged with the equal-diameter limiting groove 542 on the other side of the driving disc 54, or the variable-diameter limiting groove 541 on one side of the driving disc 54 is correspondingly arranged with the equal-diameter limiting groove 542 on the other side of the driving disc 54.

[0051] Specifically, the equal-diameter limiting groove 542 is a ring-shaped limiting groove, and a distance from each position of the equal-diameter limiting groove 542 to the center of the driving disc 54 is equal, the equal-diameter limiting groove 542 is closer to the outer edge of the driving disc 54, one end of the equal-diameter limiting groove 542 is connected with one end of the variable-diameter limiting groove 541, and the variable-diameter limiting groove 541 gradually approaches the center of the driving disc 54 away from the end connected with the equal-diameter limiting groove 542.

[0052] When the driving disc 54 rotates to make the limiting column 552 located in the equal-diameter limiting groove 542, the swing tooth 55 is stationary. When the driving disc 54 rotates to make the limiting column 552 located in the variable-diameter limiting groove 541, the limiting column 552 is driven by the pressure of the groove wall of the variable-diameter limiting groove 541, and the swing tooth 55 rotates. In this way, when it is needed to control the lifting of the lifting rod, the limiting column 552 of the swing tooth 55 can be located in the variable-diameter limiting groove 541, and the lifting rod stops lifting. For example, when the pedal body 1 is retracted to the through hole 61 on the automobile carpet 6, the limiting column 552 on the swing tooth 55 can be located in the equal-diameter limiting groove 542. Of course, in some embodiments, the second rotating driving motor 51 can also be controlled to control the lifting of the second lifting rod 22 and the third lifting rod 23.

[0053] In the embodiment, the equal-diameter limiting groove 542 and the variable-diameter limiting groove 541 on the two sides of the driving disc 54 are correspondingly arranged, so that when the swing tooth 55 on one side of the driving disc 54 moves, the swing tooth 55 on the other side of the driving disc 54 stops moving, and one of the corresponding second lifting rod 22 or the third lifting rod 23 lifts, and the other stops moving, and the left and right sides of the pedal body 1 are lifted in sequence. In some other embodiments, the equal-diameter limiting groove 542 and the variable-diameter limiting groove 541 on the two sides of the driving disc 54 are staggered, the equal-diameter limiting groove 542 on one side corresponds to the variable-diameter limiting groove 541 on the other side, or to be more accurate, the center is symmetrically arranged, the swing tooth 55 on the two sides of the driving disc 54 moves synchronously or stops synchronously, the second lifting rod 22 and the third lifting rod 23 lift or stop at the same time, and the left and right sides of the pedal body 1 lift at the same time.

[0054] As shown in FIG. 6, the pedal body 1 is lifted to the highest position, and the second lifting rod 22 and the third lifting rod 23 are in the lifting state. Figure 4As shown, the second rotary-to-linear motion conversion mechanism 52 comprises a second worm 521, a second worm wheel 522, a second rack 523 and a second gear 524. The second rack 523 is vertically arranged on the second lifting rod 22. One end of the second worm 521 is engaged with the second worm wheel 522, and the other end of the second worm 521 is provided with the second gear 524, which is engaged with the tooth portion 551 of one of the swing gears 55.

[0055] The third rotary-to-linear motion conversion mechanism 53 comprises a third worm 531, a third worm wheel 532, a third rack 533 and a third gear 534. The third rack 533 is vertically arranged on the third lifting rod 23. One end of the third worm 531 is engaged with the third worm wheel 532, and the other end of the third worm 531 is provided with the third gear 534, which is engaged with the tooth portion 551 of the other swing gear 55.

[0056] Specifically, the second worm 521 is arranged along the direction of the Z axis. The lower end of the second worm 521 passes through or is rotatably connected to the mounting base 3. The second gear 524 is arranged at a position close to the lower end of the second worm 521 to be engaged with the tooth portion 551 of the swing gear 55, which can be a helical gear. The second gear 524 can be a circular gear or a sector gear, and the second worm wheel 522 can be a circular worm wheel or a sector worm wheel.

[0057] In this embodiment, when the swing gear 55 rotates, the rotation is transmitted to the second gear 524 through the engagement of the tooth portion 551, thereby driving the second worm 521 to rotate around the Z axis, driving the second worm wheel 522 to rotate around the Y axis, and then driving the second rack 523 and the second lifting rod 22 to vertically ascend or descend.

[0058] It should be noted that the third rotary-to-linear motion conversion mechanism 53 is similar to the second rotary-to-linear motion conversion mechanism 52 in structure and movement principle, and can be referred to the second rotary-to-linear motion conversion mechanism 52.
