In addition, the seat functional interface pop-up cover of the present invention can be used for integral headrest seats as well as other seats.

Referring to fig. 1 to 3, the pop-up cover for an IPAD interface of an integrated headrest seat according to the embodiment of the present invention mainly includes a base 200, a cover body 300, a cover covering PVC 400, and a locking and unlocking mechanism 500.

Referring to fig. 31 and 32 in combination, the chrome-plated trim 100 is mounted on the back panel 610 of the integrated headrest seat 600, and particularly, at the position of the back panel 610 of the integrated headrest seat 600, and can be set as desired, mainly to facilitate the rear passenger to view the IPAD 700. The chrome-plated garnish 100 of the present invention is disposed at a position where the seat back 610 is close to the headrest 620.

With continued reference to fig. 1-3, the pop-up cover for the IPAD interface of the integrated headrest seat of the present invention is fitted into the inner hole 110 of the chrome-plated trim 100, and a cover ejecting space consisting of the cover body 300 and the cover covering PVC 400 is left in the inner hole 110 of the chrome-plated trim 100 to facilitate the ejection of the cover to open the IPAD socket hole 211.

The manner of attachment between the pop-up cover of the IPAD interface of the integrated headrest seat and the chrome trim 100 can be varied and is well known to those skilled in the art, such as snap-in, but not limited to space and not considered to be the inventive concept of the present invention and will not be described herein.

In order to facilitate the installation of the IPAD holder 710 (see fig. 34 in combination), an IPAD socket hole 211 is formed at a lower portion of the side 210 of the base 200 facing the back passenger, and two opposite walls of the IPAD socket hole 211 are respectively provided with a locking groove 211a (see fig. 35 in combination) for fixing a connector for locking the IPAD holder 710. In order to open the IPAD socket hole 211 when the IPAD700 is in use and close the IPAD socket hole 211 when not in use, the cap body 300 of the present invention is slidably disposed on the base 200, such that the cap body 300 will pop out and move to a fully open state (the state shown in fig. 33) after being unlocked, thereby opening the IPAD socket hole 211; when the cap assembly 300 is depressed and in the locked state, the IPAD socket hole 211 is closed (see state shown in FIG. 32).

The sliding arrangement of the cover body 300 on the base 200 according to the present invention can be achieved by one of the following methods, but is not limited to the following methods, and other sliding fitting methods known to those skilled in the art can be used:

referring to fig. 1 to 3 in combination with fig. 10 and 11, two guide cylinders 212 are disposed on an upper portion of a side 210 of the base 200 facing a rear passenger, and the two guide cylinders 212 may be symmetrically disposed above left and right sides of the IPAD socket hole 211. Two guide posts 310 are arranged on the cover body 300, and the two guide posts 310 extend towards the direction of the IPAD socket hole 211 and are inserted into the corresponding guide cylinders 212, and are guided by the guide cylinders 212, so that the movement stability of the cover body 300 is ensured. Of course, only one guide post 310 and one guide cylinder 212 can be used for sliding guide, and the two guide posts 310 and the two guide cylinders 212 which are symmetrically arranged are used for guiding, so that the motion stability of the cover body 300 can be improved.

In order to be ejected after the cover body 300 is unlocked, the present invention is provided with an opening spring assembly between the cover handle body 300 and the base 200. The opening spring assembly is in a charged state when the cover body 300 is locked on the base 200, and in a discharged state after the cover body 300 is unlocked, and drives the cover body 300 to perform an opening motion after unlocking, i.e., to pop up.

The opening spring assembly of the present invention includes two tension springs 800, 800a, the two tension springs 800, 800a are symmetrically disposed at the left and right sides of the movement direction of the cap body 300, the upper end of each

tension spring

800, 800a is hooked on a proper position of the base 200 (for example, above the guide cylinder 212) by the

base pin shaft

810, 810a, and the lower end is hooked on the lower end of the guide post 310 by the cap

body pin shaft

820, 820 a. Thus, when the cover body 300 is locked on the base 200, the tension springs 800 and 800a are stretched to be in an energy storage state, and after the cover body 300 is unlocked, each

tension spring

800 and 800a is in a retraction energy release state, so that the cover body 300 is driven to perform an opening movement after being unlocked, namely, to pop up. Of course, the two tension springs 800 and 800a of the present invention may be replaced by two compression springs, when the cover body 300 is locked on the base 200, the tension springs 800 and 800a are compressed to be in an energy storage state, and after the cover body 300 is unlocked, each

tension spring

800 and 800a is in an open energy release state, and drives the cover body 300 to perform an opening motion after being unlocked, i.e., to pop up. It is also possible to use only one tension spring or compression spring or more than two tension springs or more than two compression springs.

In order to lock the cover body 300 on the base 200 without springing open and to be able to spring open after unlocking, the present invention employs a unique locking and unlocking mechanism 500 to achieve the locking and unlocking of the cover body 300.

cover latch

520, 520a, and each

inclined slider

521, 521a is slidably disposed in the corresponding inclined sliding

groove

513, 513a, so that when the unlock button 510 moves, the inclined sliding

groove

513, 513a of the unlock button 510 drives the

corresponding cover latch

520, 520a to perform a telescopic motion perpendicular to the moving direction of the unlock button 510 through the

inclined slider

521, 521 a.

In addition, in order to stably mount the button spring 530, a button spring mounting hole 511a is formed on a bottom surface of the pressing portion 511, and the button spring 530 is fitted into the button spring mounting hole 511 a. In addition, in order to assemble the button lock block 540 and the button lock block spring 550, a button lock block accommodating hole 512a is formed at the middle position of the lower part of the button lock block accommodating part 512, the button lock block 540 is assembled in the button lock block accommodating hole 512a through the button lock block spring 550, the button lock block 540 can extend and retract in the button lock block accommodating hole 512a, and the moving direction of the button lock block 540 is perpendicular to the moving direction of the unlocking button 510. Assuming that the direction of movement of the unlock button 510 is on the Y-axis (the direction of movement of the bonnet body 200 is also on the Y-axis), the direction of movement of the bonnet latches 520, 520a is on the X-axis and the direction of movement of the button lock 540 is on the Z-axis.

Referring to fig. 1 to 3 and 7 in combination, in order to assemble the locking and unlocking mechanism 500, the cover body 300 is provided with a first locking and unlocking mechanism receiving slot 320, the base 200 is provided with a second locking and unlocking mechanism receiving slot 220, the first locking and unlocking mechanism receiving slot 320 corresponds to the second locking and unlocking mechanism receiving slot 220, and the outer contour of the first locking and unlocking mechanism receiving slot 320 is matched with the inner cavity of the second locking and unlocking mechanism receiving slot 220.

322, 322a is in a one-to-one relationship with and aligned with the lock holes 222, 222a such that the cover latches 520, 520a pass through the corresponding cover latch through

holes

322, 322a and are inserted into or withdrawn from the lock holes 222, 222a under the guidance of the cover latches passing through the

holes

322, 322a, thereby achieving locking and unlocking between the cover body 300 and the base 200.

In order to lock the unlocking button 510 at the unlocking position after unlocking and prevent failure of unlocking, a button lock block limiting hole 324 is formed in the lower portion of a groove wall 323 of the first locking and unlocking mechanism mounting slot 320, which is parallel to the moving direction of the cover body 300, and two sides of the groove wall 323 are connected to the

groove walls

321 and 321 a.

After the unlock button 510 is pressed down for unlocking, the button lock 540 is just aligned with the button lock limiting hole 324, and under the action of the button lock spring 550, part of the button lock 540 protrudes outwards into the button lock limiting hole 324 and part of the button lock is left in the button lock receiving hole 512a, so that the button lock 540 interacts with the unlock button 510 and the cover body 300 to limit the reset of the unlock button 540 and keep the unlock button 540 in an unlocked state.

In order to retract the button locking piece 540 into the button locking piece receiving hole 512a after the canopy body 300 is completely ejected and to smoothly reset the unlock button 540, a stopping point 224 is provided at an upper portion of a groove wall 223 of the second locking and unlocking mechanism seating slot 220 parallel to the moving direction of the canopy body 300, and both sides of the groove wall 223 are connected to the

referring to fig. 21 to 24, when the bonnet body 300 is in the initial state, the unlock button 510 is in the initial state by the button spring 530, and at the same time, the

inclined slide slots

513, 513a of the unlock button 510 drive the corresponding bonnet latches 520, 520a to move and extend outward in a direction perpendicular to the movement direction of the unlock button 510 through the inclined slide blocks 521, 521a, pass through the corresponding bonnet latch through

holes

322, 322a and are inserted into the lock holes 222, 222a under the guidance of the bonnet latch through

holes

322, 322a, so that the locking between the bonnet body 300 and the base 200 is realized. At this time, the button lock 540 is retracted into the button lock receiving hole 512a after overcoming the resistance of the button lock spring 550 under the restriction of the groove wall 323 of the first locking and unlocking mechanism seating slot 320, so that the unlocking button 510 can move up and down.

Referring to fig. 25 and 26, when the IPAD700 needs to be installed, the pressing portion 511 of the unlocking button 510 is pressed by the easy-to-deform portion 410 on the cover covering PVC 400, so that the pressing portion 511 of the unlocking button 510 is forced to move downward after overcoming the resistance of the button spring 530, i.e., to move in the unlocking direction, and the button spring 530 is compressed and charged. When the unlock button 510 moves in the unlock direction, the slanted sliding

grooves

513, 513a of the unlock button 510 drive the corresponding lid latches 520, 520a to move in a direction perpendicular to the movement direction of the unlock button 510 via the slanted sliding

blocks

521, 521a, and the lid latches retract under the guidance of the through

holes

322, 322a and exit the lock holes 222, 222a, thereby unlocking the space between the lid body 300 and the base 200.

After the cover body 300 and the base 200 are completely unlocked, the button lock 540 moves to the position of the button lock limiting hole 324 on the cover body 300 along with the unlocking button 510, part of the button lock protrudes outwards into the button lock limiting hole 324 under the action of the button lock spring 550, and part of the button lock is left in the button lock bearing hole 512a, so that the button lock 540 interacts with the unlocking button 510 and the cover body 300 to limit the resetting of the unlocking button 540, and the unlocking button 540 is kept in an unlocked state. At this time, the unlocking button 510 cannot move up and down, and can only move up and down along with the cover body 300, so that the unlocking button 510 can be locked at an unlocking position after being unlocked, and the unlocking failure is prevented.

Referring to fig. 27 and 28, after the cover body 300 and the base 200 are unlocked, the cover body 300 is ejected upward by the two tension springs 800 and 800a to open the IPDA socket hole 211 on the base 200, and then the IPAD bracket 711 is inserted into the IPDA socket hole 211.

cover locking bolts

520 and 520a to extend outwards for locking, and the next unlocking operation is facilitated.

Referring to fig. 29 and 30, after the button lock block 540 is disengaged from the cover body 300, the unlock button 510 moves back to the original state (i.e., the locked state) in the locking direction by the releasing force of the button spring 530, and the inclined sliding

grooves

513, 513a of the unlock button 510 drive the corresponding cover latches 520, 520a to move outward in the direction perpendicular to the moving direction of the unlock button 510 to return to the original state (i.e., the locked state), at this time, the button lock block 540 retracts back to the button lock block receiving hole 512a to be in the original state (i.e., the locked state) again after overcoming the resistance of the button lock block spring 550 under the restriction of the groove walls 323 of the first locking and unlocking mechanism receiving slot 320, and waits for the next unlocking.

After the IPAD700 is used, the joint of the IPAD bracket 710 can be pulled out from the IPAD socket hole 211, then the bonnet body 300 is pressed down, the bonnet body 300 drives the locking and unlocking mechanism 500 to move downwards together, when the bonnet body 300 drives the locking and unlocking mechanism 500 to move to the locking position with the base 200, under the action of the button spring 530, the inclined sliding

grooves

513 and 513a on the unlocking button 510 drive the corresponding

bonnet locking tongues

520 and 520a to move in the direction perpendicular to the movement direction of the unlocking button 510 to extend outwards again, and the

bonnet locking tongues

520 and 520a are guided by the bonnet locking tongue through

holes

322 and 322a and inserted into the lock holes 222 and 222a, so that the locking between the bonnet body 300 and the base 200 is realized.
