Description

Technical Field

[0001] The utility model relates to the field of footrests, in particular to a novel electric footrest. Background Art

[0002] Due to the limitation of the space inside the car, the rear passengers sit for a long time, which leads to poor comfort. As people's requirements for car comfort are getting higher and higher, for high-end luxury models, consumers have begun to choose to install footrests on the backrests of the front seats to provide a place for the rear passengers to put their feet, so as to achieve a lying position and improve comfort. The footrests are usually manual footrests or electric footrests. The manual footrests have fewer adjustable gears and are inconvenient to adjust. The electric footrests are easier to adjust than the manual footrests. The existing electric footrests are usually driven by direct meshing of gear plates, and the direct connection of the gear plates has more requirements on the spatial structure, and the exposed part is difficult to handle, which will lead to a reduction in the actual foot placement space. Utility Model Content

[0012] Beneficial effects of the utility model:

[0013] 1. Compared with the traditional electric footrest, gear tooth plate direct meshing drive is usually adopted, and the direct connection of the tooth plate has more requirements on the spatial structure, and the exposed part is difficult to handle, which will lead to a reduction in the actual foot placement space. At the same time, this solution has a greater impact on the seat frame, and a special frame needs to be developed simultaneously, resulting in a long development cycle and high cost. The utility model includes an installation component, a support component, a footrest upper plate, a footrest lower plate, a frame component, a spring bracket and a first footrest mounting bolt, wherein the frame component is the main structure for realizing the function, including a drive motor, a tooth plate connecting rod module and a rotating shaft module. The tooth plate connecting rod module is driven by the drive motor to drive the footrest to rotate and unfold / store. The tooth plate connecting rod module reduces the requirements of the footrest on the seat frame, increases the flexibility of the footrest rotation axis setting, and enhances the applicability of the footrest solution; reduces development risks and cycles; by distributing the driven crank and the footrest body on both sides of the axis centerline, the restrictions on the position of the footrest rotation axis can be reduced, and the rotation axis can be as close to the seat back as possible.

[0014] 2. By setting a mounting assembly to detachably connect the support assembly, the footrest and the frame assembly, the frame assembly and the footrest can be installed and fixed at different positions, so that it can be applied to different frame platforms and has stronger applicability. By setting a second footrest mounting bolt, the left end of the frame assembly can be detachably connected to the first seat side bracket, by setting a third footrest mounting bolt, the right end of the frame assembly can be detachably connected to the second seat side bracket, and by setting a fourth footrest mounting bolt, the left end of the frame assembly can be detachably connected to the third seat side bracket, so that the frame assembly can be removed and installed and fixed on different seats. By distributing the driven crank and the footrest body on both sides of the axis, the restriction on the position of the footrest rotation axis can be reduced, making the design of the shielding plastic part simpler. It is not necessary to complete the simple shielding of the appearance in the case of the "gooseneck" rod and the belly rod retreat structure. It can be simply shielded by setting a shielding plastic decorative cover, which can provide as large a use space as possible and better space utilization.

[0015] 3. By setting the toothed plate connecting rod module and the rotating shaft module connecting rod structure force arm design, the strength and sensitivity design can be better balanced: the lifting load of the footrest near the unfolded use position is relatively larger, and the adjustment speed is relatively smaller, and the tightening force near the storage position is relatively smaller, and the adjustment speed is relatively larger; it can better meet the needs of users; it can better meet the needs of users. The specific implementation description is as follows: the drive motor drives the toothed plate to rotate clockwise around the toothed plate rotating shaft by clockwise rotation, so that the toothed plate pushes the connecting rod downward, and then the driven crank rotates counterclockwise around the footrest rotating shaft. During the rotation process, the driven crank and the footrest are relatively stationary. After the rotation reaches the driven crank, the footrest rotates counterclockwise around the footrest rotating shaft to quickly unfold the footrest. At this time, the rotation speed is relatively low and the load capacity is relatively high. On the contrary, when the driving motor rotates counterclockwise, the rotation speed is relatively high and the load capacity is relatively low, thereby preventing the back panel from being crushed. During the clockwise and counterclockwise rotation, the lever arm ratio of the connecting rod changes, so that the high load near the use state can be better balanced, the sensitivity is higher, and different usage needs can be met, so that near the storage position, the footrest is initially unfolded at a fast speed to reduce waiting time; the speed is reduced when it is unfolded to the use position, which is convenient for the occupant to adjust precisely.

[0031] The driving motor 501 is then used to drive the footrest to be unfolded or folded. When the footrest needs to be unfolded, the driving motor 501 drives the toothed plate 516 to rotate slowly clockwise around the toothed plate rotating shaft 518 by rotating clockwise, so that the toothed plate 516 pushes the connecting rod 517 downward, thereby causing the driven crank 513 to rotate slowly counterclockwise around the footrest rotating shaft 512.

By setting the mounting assembly 1 to detachably connect the support assembly 2, the footrest and the frame assembly 5, the frame assembly 5 and the footrest can be installed and fixed at different positions, so that it can be suitable for It is used for different skeleton platforms and has stronger applicability. The footrest is driven to be unfolded or folded by the driving motor 501. When the footrest needs to be unfolded, the driving motor 501 drives the tooth plate 516 to rotate slowly clockwise around the tooth plate shaft 518 by clockwise rotation, so that the tooth plate 516 pushes the connecting rod 517 downward, and then the driven crank 513 rotates slowly counterclockwise around the footrest shaft 512. When the rotation reaches the driven crank 513, the footrest rotates counterclockwise around the footrest rotation axis to quickly unfold the footrest. When the footrest needs to be folded, the above rotation process is reversed by rotating the driving motor 501 counterclockwise to fold the footrest. During the clockwise and counterclockwise rotation, the force arm ratio of the connecting rod 517 changes, so that it can better balance the high load near the use state, with higher sensitivity, and can also meet different use requirements, so that the waiting time is reduced when unfolding, and it is slowly folded when folded close to the storage position, thereby protecting the back panel and preventing it from being crushed by excessive speed.
