As shown in FIG. 6, FIG. 7 and FIG. 8B, the press latch comprises a button assembly 30, a first locking hook 50 and a second locking hook 60. When the button assembly 30 is in an unpressed state, the first locking hook 50 interlocks with the second locking hook 60, and a front end of the first locking hook 50 is locked in the lock hole 224; As shown in FIG. 6, FIG. 7 and FIG. 8C, when the button assembly 30 is in a pressed state, the second locking hook 60 and the first locking hook 50 are unlocked, and the front end of the first locking hook 50 disengages from the lock hole 224.

Further referring to FIG. 1 through FIG. 7, the foam door body 10 comprises a peripheral trim strip 11, a receiving hole 12 may be disposed on a side of the peripheral trim strip 11, and the button assembly 30 may be received in the receiving hole, wherein the button assembly 30 comprises a button portion 31 and a push rod portion 32, and the button portion 31 may be exposed from the receiving hole 12 to facilitate the user to press the button portion 31.

In a preferred embodiment, one of a top trim strip and a bottom trim strip of the peripheral trim strip 11 is provided with the receiving hole 12, so that the user may release the interlocking relationship between the first locking hook 50, the second locking hook 60 and the first hook 22 by pressing down or up the button portion 31, thereby facilitating the detachment of the decorative panel 20. In the present embodiment, the receiving hole 12 is disposed in the top trim strip of the peripheral trim strip 11.

As shown in FIG. 6 and FIG. 7, the button portion 31 comprises a stop 33, which protrudes from a side wall of the button portion 31; a receiving groove 121 is disposed on an inner wall of the receiving hole; wherein the button assembly 30 is received in the receiving hole 12, and the stop 33 is received in the receiving groove 121.

Furthermore, an elastic member 34 is sleeved outside the push rod portion 32 of the button assembly 30; a resisting portion 122 protrudes from the inner wall of the receiving hole 12, and the resisting portion 122 protrudes toward an interior of the receiving hole 12; when the button assembly 30 is received in the receiving hole 12, opposite ends of the elastic member 34 elastically abut against the button portion 31 and the resisting portion 122, respectively.

In the present embodiment, an end of the push rod portion 32 away from the button portion 31 protrudes from the resisting portion 122 and extends toward the second locking hook 60. After the button portion 31 is pressed, the push rod portion 32 moves toward the second locking hook 60, and the elastic member 34 is compressed between the button portion 31 and the resisting portion 122; after the button portion 31 is released, the compressed elastic member 34 extends to provide an elastic force, and the button portion 31 and the push rod portion 32 return from the pressed state to the unpressed state under action of the elastic force.

In addition, during the returning process of the button portion 31, the stop 33 slides in the receiving groove 121. After the button portion 31 returns, the stop 33 is stopped by an end groove wall (or an upper end groove wall) of the receiving groove 121 and does not move any more, thereby preventing the button portion 31 from ejecting out of the receiving hole 12 after the return and disengaging from the receiving hole 12.

As shown in FIG. 7, a box 40 is also disposed in the foam door body 10, and the box 40 may be integrally formed with the peripheral trim strip 11. An opening portion 42 is disposed on a side of the box 40 facing towards the receiving hole 12, and communicates a receiving space 41 in the interior of the box 40 with the receiving hole 12. The button portion 31 is pressed so that the push rod portion 32 extends through the opening portion 42 into the receiving space 41 and abuts against a lever portion 61 of the second locking hook 60.

The first locking hook 50 and the second locking hook 60 that may be interlocked are respectively received in the receiving space 41 in the box 40, and the first locking hook 50 and the second locking hook 60 are pivotally connected to a side wall of the box 40.

Specifically, a first rotating shaft 53 is disposed between the first locking hook 50 and the side wall of the box 40, a first torsion spring is disposed on the first rotating shaft 53, the first torsion spring is sleeved in the first rotating shaft 53, a fixe end of the torsion spring is fixed to the side wall of the box 40, and a free end of the torsion spring interacts with the first locking hook 50, wherein the first torsion spring provides a torsional force causing the first locking hook 50 to rotate around the first rotating shaft 53. A second rotating shaft 63 is disposed between the second locking hook 60 and the side wall of the box 40, a second torsion spring is disposed on the second rotating shaft 63, the second torsion spring is sleeved in the second rotating shaft 63, a fixed end of the second torsion spring is fixed to the side wall of the box 40, and a free end of the second torsion spring interacts with the second locking hook 60, wherein the second torsion spring provides a torsional force causing the second locking hook 60 to rotate around the second rotating shaft 63, and a hook 61 at a front end of the second locking hook 60 catches a hook-catching groove 51 at a rear end of the first locking hook 50.

In the present embodiment, for example, the torsion force provided by the first torsion spring causes the first locking hook 50 to rotate clockwise around the first rotating shaft 53, and then a second arm 522 of a notched slot 52 at the front end of the first locking hook 50 has a tendency to disengage from the lock hole 224; the torsional force provided by the second torsion spring causes the second locking hook 60 to rotate counterclockwise around the second rotating shaft 63, and the hook 61 at the front end of the second locking hook 60 has a tendency to catch the hook-catching groove 51.

It needs to be appreciated that when the first hook 22 is not inserted into a first hook groove 13, the first torsion spring is in a natural state (or a force-not-received state), and the second torsion spring is in a torsional state (or a force-received state). At this time, the torsional force provided by the second torsion spring causes the hook 61 at the front end of the second locking hook 60 to have a tendency to catch the hook-catching groove 51 at the rear end of the first locking hook 50.

In addition, when the first hook 22 is inserted into the first hook groove 13, an extension portion 223 presses against a first arm portion 521 by using the dead weight of the decorative panel 20 and the frame 21, the first locking hook 50 pivots around the first rotating shaft 53, and the first torsion spring is twisted. At this time, the hook 61 smoothly catches the hook-catching groove 51 by virtue of a counterclockwise acting force applied by the second torsion spring on the second locking hook 60. The first hook 22 is inserted into the first hook groove 13; after the front end of the first locking hook 50 and the lock hole 224 interlock each other, the torsion force generated by the first torsion spring is smaller than a gravitational force generated by the decorative panel 20 and the frame 21, to maintain the locked state of the first locking hook 50 and the lock hole 224. In addition, since the first locking hook 50 pivots, a direction of the torsional force generated by the first torsion spring is opposite to a direction of a pressing force by which the extension portion 223 of the first hook 22 presses against the first arm portion 521.

In addition, the button portion 31 is pressed so that the push rod portion 32 extends into the receiving space 41 and pushes against the lever portion 62 at the rear end of the second locking hook 60. A pushing force applied by the push rod portion 32 on the lever portion 62 is greater than the torsional force exerted by the second torsion spring on the second locking hook 60. The second locking hook 60 pivots around the second rotating shaft 63, the hook 61 at the front end of the second locking hook 60 is lifted upward, the hook 61 disengages from the hook-catching groove 51 at the rear end of the first locking hook 50, and the second locking hook 60 and the first locking hook 50 are unlocked. In the absence of of the constraint of the second locking hook 60, the first torsion spring in the counterclockwise torsional state rotates clockwise to return to the natural state, driving the second arm portion 522 of the notched slot 52 at the front end of the first locking hook 50 to disengage from the lock hole 224, and the first hook 22 and the first locking hook 50 are unlocked. Furthermore, the limitation of the displacement of the first hook 22 and the first locking hook 50 in the up-down direction is released, the first hook 22 may be removed from the first hook groove 13, and the limitation of the displacement of the decorative panel 20 and the foam door body 10 in the up-down direction is also released.
