Description

Technical Field

[0001] This application relates to the field of seat technology, and in particular to an automobile footrest and a seat having the footrest. Background Technology

[0002] A car seat footrest is a comfort accessory that extends the seat and is installed under the seat. Its main function is to provide support for the passenger's feet, preventing them from dangling in the air and effectively relieving leg fatigue and discomfort caused by long journeys.

[0003] Currently, referring to the published patent CN218141205U, the car seat footrest includes a leg support assembly and a foot pedal. The leg support assembly is rotatably mounted on the seat frame via a first adjuster, and the foot pedal is rotatably mounted on the leg support assembly via a second adjuster. When the car footrest is extended, the leg support assembly can support the passenger's legs, and the foot pedal can support the passenger's feet.

[0004] When the car footrest provides support, the leg support assembly bears most of the passenger's leg weight. When the leg support assembly bears heavy weight for a long time, the teeth of the gears inside the adjuster are prone to deformation or even breakage, which will affect the rotation of the leg support assembly. Utility Model Content

[0005] In order to improve the load-bearing capacity of a car pedal, this application provides a car pedal and a seat having the pedal.

[0006] Firstly, the automotive pedal provided in this application adopts the following technical solution:

The first rotating assembly is mounted on a seat frame, the leg support assembly is located at the rotating end of the first rotating assembly, the second rotating assembly is mounted on the leg support assembly, and the foot pedal is located at the rotating end of the second rotating assembly. The first rotating assembly includes a first mounting base, a first driving member, a first lead screw, a first connecting plate, a second connecting plate, a third connecting plate, a fourth connecting plate, a fifth connecting plate, and a pull rod. The first mounting base is fixedly mounted on the seat frame, the first driving member is mounted on the first mounting base, the first lead screw is located at the driving end of the first driving member, the first connecting plate is rotatably mounted at the end of the first lead screw, the second connecting plate is rotatably mounted on the first mounting base, the pull rod is mounted on the second connecting plate, the end of the first connecting plate is rotatably mounted on the pull rod, the third connecting plate is rotatably mounted on the first mounting base, and both the fourth and fifth connecting plates are rotatably mounted on the second connecting plate. The two ends of the fourth connecting plate are rotatably connected to the end of the third connecting plate and the foot pedal, respectively, and the end of the fifth connecting plate is rotatably connected to the foot pedal.

[0008] By adopting the above technical solution, when the first rotating component drives the leg support assembly to rotate, the first driving component drives the first lead screw to move on the first mounting base. The first lead screw drives the pull rod to move through the first connecting plate, the pull rod drives the second connecting plate to rotate, the second connecting plate drives the fourth and fifth connecting plates to rotate, the fourth connecting plate drives the third connecting plate to rotate, and the rotation of the fourth and fifth connecting plates drives the leg support assembly to rotate, thereby enabling the leg support assembly to unfold and retract. With this configuration, using the first lead screw, pull rod, and multiple connecting plates as the driving structure of the leg support assembly, when the leg support assembly bears heavy loads for extended periods, the multiple connecting plates can evenly distribute the load-bearing capacity, and the lead screw structure has higher stability, thus improving the load-bearing performance of the car's footrest.

[0009] Preferably, the leg support assembly includes a support plate, a support plate, a slide rail, a second drive member, a second lead screw, and a pull block. The two ends of the slide rail are respectively connected to the support plate and the support plate via mounting brackets. The fourth connecting plate and the fifth connecting plate are rotatably connected to the slide rail. The second drive member is disposed on the support plate, the second lead screw is disposed on the drive end of the second drive member, and the pull block is fixedly disposed on the support plate. The second lead screw is threaded through the pull block.

[0010] By adopting the above technical solution, the fourth and fifth connecting plates drive the support plate and the tray to rotate via the slide rail, which in turn drives the leg support assembly to rotate. The second drive unit drives the second lead screw to rotate, the second lead screw drives the pull block to move, and the pull block drives the tray to move, thereby unfolding the leg support assembly and making it convenient for passengers to place their legs on the tray.

[0011] Preferably, the second rotating assembly includes a third driving member, a transmission rod, a second mounting base, an angle adjuster, a first connecting rod, a second connecting rod, and a third connecting rod. The third driving member is mounted on the leg support assembly, the second mounting base is mounted on the leg support assembly, the angle adjuster is mounted on the second mounting base, the transmission rod is mounted on the driving end of the third driving member and is connected to the angle adjuster, the first connecting rod is mounted on the angle adjuster, the second connecting rod is rotatably mounted on the second mounting base, the third connecting rod is rotatably mounted at the ends of the first and second connecting rods, and the foot pedal is mounted on the third connecting rod.

[0012] By adopting the above technical solution, the third driving component drives the angle adjuster to rotate via the transmission rod, the angle adjuster drives the first link to rotate, the first link drives the second link to rotate on the second mounting base via the third link, the first link and the second link together drive the third link to rotate, and the third link then drives the foot pedal to rotate, thereby enabling the foot pedal to be extended or retracted.

[0013] Preferably, the middle part of the pull rod has a protrusion in the direction away from the leg support assembly, and the protrusion of the pull rod is used to avoid the pull block and the third drive member.

[0014] By adopting the above technical solution, when the car pedal is in the retracted state, the protrusion of the lever avoids the lever block and the third drive component, so that the lever will not interfere with other components.

[0015] Preferably, there are two first mounting seats, both of which are fixedly mounted on the seat frame, and a connecting rod is fixedly mounted on each of the two first mounting seats.

[0016] By adopting the above technical solution, the connecting rod reinforces the two first mounting seats, making the first rotating component more stable.

[0017] Preferably, the tray is bent around the periphery away from the seat frame to form a flange.

[0018] By adopting the above technical solution, when the car pedal is in the retracted state, the flange on the side of the tray can cover the second rotating component, and when the car pedal is in the extended state, the flange on the side of the tray can cover the slide rail, thus improving the aesthetics of the car pedal.

[0019] Preferably, the side of the flange furthest from the seat frame has an avoidance groove.

[0020] By adopting the above technical solution, when the car pedal is in the unfolded state, the clearance groove can avoid the second rotating component, thereby facilitating the smooth unfolding of the pedal.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. The first lead screw, tie rod and multiple connecting plates are used as the driving structure of the leg support assembly. When the leg support assembly is under heavy load for a long time, the multiple connecting plates can distribute the load evenly, and the stability of the lead screw structure is higher, thereby improving the load-bearing performance of the car pedal.

[0025] 2. With the help of the fourth and fifth connecting plates, the support plate and the tray are rotated through the slide rail, which in turn drives the leg support assembly to rotate. The second drive unit drives the second lead screw to rotate, the second lead screw drives the pull block to move, and the pull block drives the tray to move, so that the leg support assembly can be unfolded, making it convenient for passengers to place their legs on the tray.

[0026] 3. The third drive unit drives the angle adjuster to rotate via the transmission rod. The angle adjuster drives the first link to rotate. The first link drives the second link to rotate on the second mounting base via the third link. The first link and the second link together drive the third link to rotate. The third link then drives the foot pedal to rotate, thereby enabling the foot pedal to be extended or retracted. Attached Figure Description

Detailed Implementation

[0033] The following is in conjunction with the appendix Figures 1-5 This application will be described in further detail.

[0034] This application discloses an automobile pedal.

[0035] Reference Figure 1 and Figure 2A car foot pedal includes a leg support assembly 3, a foot pedal 2, a first rotating assembly 4, and a second rotating assembly 5. The first rotating assembly 4 is mounted on a seat frame 1, the leg support assembly 3 is mounted on the rotating end of the first rotating assembly 4, the second rotating assembly 5 is mounted on the end of the leg support assembly 3 away from the first rotating assembly 4, and the foot pedal 2 is mounted on the rotating end of the second rotating assembly 5. The first rotating assembly 4 can drive the leg support assembly 3 to rotate, and the second rotating assembly 5 can drive the foot pedal 2 to rotate, allowing the car foot pedal to extend and retract.

[0036] Reference Figure 3 Specifically, the first rotating assembly 4 includes a first driving component 42, a first lead screw 43, a pull rod 49, two first mounting seats 41, a first connecting plate 44, a second connecting plate 45, a third connecting plate 46, a fourth connecting plate 47, and a fifth connecting plate 48. The two first mounting seats 41 are fixedly mounted on the seat frame, and a connecting rod 7 is mounted on the two first mounting seats 41. The two ends of the connecting rod 7 pass through the two first mounting seats 41 and are fixedly connected to the two first mounting seats 41.

[0037] The first driving element 42 is fixedly mounted on a first mounting base 41, the first lead screw 43 is mounted on the driving end of the first driving element 42, and the first connecting plate 44 is rotatably mounted on the end of the first lead screw 43. In this application, the first driving element 42 can be a servo motor, and the first driving element 42 can drive the first lead screw 43 to reciprocate along its own axis.

[0038] Two second connecting plates 45 are rotatably mounted on two first mounting bases 41, and the two ends of the pull rod 49 are fixedly connected to the ends of the two second connecting plates 45. Two third connecting plates 46 are rotatably mounted on the two first mounting bases 41, and the two third connecting plates 46 are located above the two second connecting plates 45.

[0039] The ends of the two fourth connecting plates 47 are rotatably connected to the two third connecting plates 46, the middle of the two fourth connecting plates 47 is rotatably connected to the middle of the two second connecting plates 45, and the ends of the two fourth connecting plates 47 away from the third connecting plates 46 are rotatably connected to the leg support assembly 3. The two fifth connecting plates 48 are rotatably mounted on the ends of the two second connecting plates 45, and the ends of the two fifth connecting plates 48 are rotatably connected to the leg support assembly 3.

[0040] A protrusion 6 is formed in the middle of the pull rod 49 in the direction away from the leg support assembly 3. When the car foot pedal is in the retracted state, the protrusion 6 structure on the pull rod 49 will form a precise spatial avoidance relationship with the components in the leg support assembly 3 and the second rotating assembly 5, eliminating the possibility of the pull rod 49 contacting or colliding with other components.

[0041] The first driving component 42 drives the first lead screw 43 to displace on the first mounting base 41. The first lead screw 43 causes the pull rod 49 to move through the first connecting plate 44, which in turn drives the second connecting plate 45 to rotate. The rotation of the second connecting plate 45 will drive the fourth connecting plate 47 and the fifth connecting plate 48 to rotate synchronously. At the same time, the fourth connecting plate 47 transmits the driving force to the third connecting plate 46 to rotate. Under the coordinated rotation of the fourth connecting plate 47 and the fifth connecting plate 48, the leg support assembly 3 realizes the rotation action, and finally completes the unfolding and retracting function of the leg support assembly 3. The first lead screw 43, the pull rod 49 and the multiple connecting plates together constitute the driving system of the leg support assembly 3. When the leg support assembly 3 is subjected to a large load for a long time, the multiple connecting plates can achieve a uniform distribution of the load-bearing capacity. In addition, the lead screw structure itself has high stability. The combination of the two effectively improves the load-bearing performance of the car foot pedal.

[0042] Reference Figure 3 , Figure 4 and Figure 5 Specifically, the leg support assembly 3 includes a support plate 31, a support plate 32, a second drive member 34, a second lead screw 35, a pull block 36, and two slide rails 33. Each slide rail 33 is rotatably connected to the ends of a fourth connecting plate 47 and a fifth connecting plate 48. The support plate 31 is fixedly mounted on one end of the two slide rails 33 via a mounting bracket, and the support plate 32 is fixedly mounted on the other end of the two slide rails 33 via a mounting bracket. The second rotating assembly 5 is mounted on the support plate 32. The second drive member 34 is fixedly mounted on the support plate 31, the pull block 36 is fixedly mounted on the support plate 32, and the second lead screw 35 is mounted on the driving end of the second drive member 34, with the second lead screw 35 threaded through the pull block 36. In this application, the second drive member 34 can be selected as a servo motor, and the second drive member 34 can drive the second lead screw 35 to rotate.

[0043] During the movement of the leg support assembly 3, the fourth connecting plate 47 and the fifth connecting plate 48 form a linkage mechanism through the slide rail 33 structure, driving the support plate 31 and the support plate 32 to rotate synchronously, thereby driving the entire leg support assembly 3 to achieve the rotation function. At the same time, the second driving member 34 outputs power to cause the second lead screw 35 to rotate. The second lead screw 35 drives the pull block 36 to produce linear displacement through the threaded transmission. The pull block 36 further transmits power to the support plate 32 and drives the support plate 32 to move. The rotation adjustment of the leg support assembly 3 is achieved through the coordinated action of the connecting plates and the slide rail 33. At the same time, the extension and retraction of the support plate 32 is completed by the transmission of the lead screw and the pull block 36. The cooperation of the two allows the leg support assembly 3 to smoothly unfold to the preset position.

[0044] Specifically, the second rotating assembly 5 includes a third driving member 51, a transmission rod 52, two second mounting seats 53, an angle adjuster 54, a first connecting rod 55, a second connecting rod 56, and a third connecting rod 57. The third driving member 51 is fixedly mounted on the support plate 32, and the transmission rod 52 is mounted on the driving end of the third driving member 51. In this application, the third driving member 51 can be selected as a servo motor, and the third driving member 51 can drive the transmission rod 52 to rotate.

[0045] Two second mounting seats 53 are mounted on the support plate 32, and the two second mounting seats 53 are fixedly connected to the ends of the two slide rails 33. Two angle adjusters 54 are mounted on the two second mounting seats 53, and the two ends of the transmission rod 52 are respectively connected to the two angle adjusters 54. Two first connecting rods 55 are respectively mounted on the rotating ends of the two angle adjusters 54, and two second connecting rods 56 are rotatably mounted on the two second mounting seats 53. One end of each of the two third connecting rods 57 is rotatably connected to the end of the two second connecting rods 56, the middle part of each of the two third connecting rods 57 is rotatably connected to the end of the two first connecting rods 55, and the other end of each of the two third connecting rods 57 is fixedly connected to both ends of the foot pedal 2.

[0046] The power output from the third drive unit 51 is transmitted to the two angle adjusters 54 via the transmission rod 52, causing the angle adjusters 54 to rotate. During rotation, the angle adjusters 54 transmit power to the first link 55, causing the two first links 55 to rotate synchronously. The first link 55, through its connection with the third link 57, further drives the second link 56 to complete the rotation on the second mounting base 53. In this process, the first link 55 and the second link 56 form a coordinated linkage mechanism, jointly driving the third link 57 to rotate, and the third link 57 ultimately transmits power to the foot pedal 2, enabling the foot pedal 2 to adjust its extension or retraction.

[0047] The three side walls of the support plate 32 away from the seat frame 1 are all bent to form flanges 8. Both ends of the flanges 8 on the side away from the seat frame 1 are provided with clearance grooves 9, and the two clearance grooves 9 correspond to the two first connecting rods 55.

[0048] When the car pedal is in the retracted state, the flange 8 on the side of the support plate 32 effectively shields the second rotating component 5 and the slide rail 33, preventing them from being directly exposed. When the car pedal is in the extended state, the flange 8 precisely covers the slide rail 33, making it invisible. Through the targeted shielding effect of the flange 8 in different states, the exposed area of ​​the mechanical structure is reduced, visually optimizing the overall appearance of the car pedal and significantly improving its neatness and aesthetics. In addition, when the car pedal is in the extended state, the two clearance slots 9 provide ample space for the second rotating component 5 to move, preventing interference between the two during movement.

[0049] The implementation principle of a car pedal according to an embodiment of this application is as follows: the unfolding of the car pedal involves the following three steps: First, the second driving member 34 outputs power to cause the second lead screw 35 to rotate. The second lead screw 35 drives the pull block 36 to produce linear displacement through threaded transmission. The pull block 36 further transmits power to the support plate 32 and drives the support plate 32 to move and unfold. Second, the first driving member 42 drives the first lead screw 43 to produce displacement on the first mounting base 41. The first lead screw 43 causes the pull rod 49 to move through the first connecting plate 44, thereby driving the second connecting plate 45 to rotate. The rotation of the second connecting plate 45 will cause the fourth connecting plate 47 and the fifth connecting plate 48 to rotate synchronously. At the same time, the fourth connecting plate 47 transmits driving force to the third connecting plate 46 to rotate. Under the coordinated rotation of the fourth connecting plate 47 and the fifth connecting plate 48, the leg support assembly 3 realizes the rotation action, and finally completes the unfolding of the leg support assembly 3. 43. The pull rod 49 and multiple connecting plates together constitute the drive system of the leg support assembly 3. When the leg support assembly 3 is subjected to a large load for a long time, the multiple connecting plates can achieve a uniform distribution of the load-bearing capacity. In addition, the screw structure itself has high stability. The combination of the two effectively improves the load-bearing performance of the car foot pedal. In the third step, the power output by the third drive component 51 is transmitted to the two angle adjusters 54 through the transmission rod 52, causing the angle adjusters 54 to rotate. During the rotation, the angle adjusters 54 transmit power to the first link 55, causing the two first links 55 to rotate synchronously. The first link 55, through its connection with the third link 57, further drives the second link 56 to complete the rotation action on the second mounting seat 53. The first link 55 and the second link 56 form a coordinated linkage mechanism, jointly driving the third link 57 to rotate. The third link 57 then transmits the power to the foot pedal 2, enabling the foot pedal 2 to unfold.

[0050] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
