Description

TECHNICAL FIELD

[0001] The present invention relates to a vehicle, and more particularly to a sliding door mechanism. BACKGROUND

[0002] A zero-gap sliding box is known in the art, as shown in FIG. 13 The top surface of the cover plate 100 (solid line) is level with the top surface of the perimeter member 200 in the closed state. After the button is pressed to unlock, the cover plate 100 (dashed line) is tilted downward into the lower portion of the perimeter member 200 to open the storage space 300.

[0003] Obviously, when an external force is applied vertically downward to the tail portion 101 of the cover plate 100, for example, a heavy object is placed thereon, it can cause the cover plate 100 to be unlocked by mistake, i.e. the cover plate 100 is unlocked and opened without pressing the button. In order to avoid this unlocking by mistake, a mechanical link self-locking structure is used on the sliding box to prevent the collapse of the tail portion pressing. However, this not only leads to a complex structure, but also the mechanical self-locking can be released in the case of a larger pressing force, and the reliability is low. SUMMARY

[0004] In order to solve the unlocking by mistake problem in the prior art described above, the present invention provides a sliding door mechanism.

[0005] According to the sliding door mechanism of the present invention, it comprises a base; a cover plate sliding relative to the base; a mechanism arranged to cause the cover plate to slide between a closed state and an open state, the mechanism comprising a pull rod rotatably mounted on the cover plate and a link rotatably mounted on the pull rod; and a button movably mounted on the cover plate; the link is rotated in response to the movement of the button so as to unlock the cover plate from the closed state; when the cover plate is subjected to a vertical external force in the closed state, the rotation of the link is limited to prevent the cover plate from being unlocked.

[0006] Preferably, the base has a track comprising a locking groove, and the link has a laterally protruding locking pin, the locking pin being accommodated in the locking groove when the cover plate is in the closed state.

[0007] Preferably, the mechanism further comprises a torsion spring acting on the link to ensure the locking pin to enter the locking groove.

[0008] Preferably, the track further comprises a variable track groove, and the pull rod has a first shaft and a second shaft protruding laterally, the first shaft and the second shaft being accommodated in the variable track groove.

[0009] Preferably, the variable track slot comprises a straight segment and a vertical segment extending from the straight segment, and the first shaft is accommodated in the vertical segment when the cover is in the closed state.

[0010] Preferably, the first shaft and the drop bolt move into the straight segment after the cover is unlocked from the closed state.

[0011] Preferably, the locking slot extends in an arc from the straight segment toward a direction opposite to the vertical segment.

[0012] Preferably, the depth of the locking slot is less than the depth of the variable track slot.

[0013] Preferably, the push rod of the button is formed with a circular arc segment, which acts on the connecting rod to rotate the connecting rod while the pull rod remains stationary during the unlocking process.

[0014] Preferably, the push rod further has a straight segment, which drives the cover to open after unlocking.

[0015] Preferably, the push rod further has a straight segment, and the mechanism further comprises a shaft sleeve rotatably mounted on the connecting rod, and the push rod acts on the shaft sleeve to apply force to the connecting rod through the button.

[0016] Preferably, the sliding door mechanism further comprises a hook mounted on the connecting rod, and the base has a labyrinth, and the hook cooperates with the labyrinth to limit the cover to remain in the open state.

[0017] The sliding door mechanism according to the present application, when pressed in the closed state, keeps the cover in the closed state and cannot be unlocked, and only the push of the button on the connecting rod can unlock the cover, thereby solving the problem of false unlocking in the prior art. Moreover, the sliding door mechanism according to the present application has a simple structure and high reliability. In summary, the sliding door mechanism of the present application can realize zero-difference matching of the cover and the surrounding parts, prevent the cover tail from collapsing under positive pressure, and prevent the pinch problem caused by the collapse.

[0033] The preferred embodiments of the present invention are given below with reference to the accompanying drawings and described in detail.

[0034] like FIGS. 1A-1B As shown, according to a preferred embodiment of the invention, the sliding door mechanism is a sliding variable-track storage box C installed in front of the sub-dashboard of the vehicle V, located in front of the center console FC. It should be understood that the sliding variable-track storage box C here is merely an example and not a limitation; other similar sliding door mechanisms can be installed in any other desired location within the vehicle.

[0035] As shown in FIG. 2 , the sliding door mechanism comprises a button 10, a base 20, a cover plate 30 and a mechanism 40, wherein the button 10 is movably installed on the cover plate 30, and the cover plate 30 is movably installed on the base 20 through the mechanism 40.

[0036] As shown in FIG. 2 , the sliding door mechanism 40 further comprises a hook 50 installed on the mechanism 40 (the connecting rod 41, see FIG. 5 ), and the base 20 is provided with a labyrinth 21, and the hook 50 cooperates with the labyrinth 21 to limit the cover plate 30, and the specific check and unlocking process will be described in detail below. FIG. 3 In addition, the base 20 is also provided with a ramp-shaped track 22, and the sliding door mechanism 40 (the connecting rod 41 and the pull rod 42, see FIG. 5 ) cooperates with the track 22 to define the closing state and the opening state of the cover plate 30, and the specific action mode will be described in detail below. FIG. 9 FIG. 11

[0037] As shown in FIG. 2 , the sliding door mechanism further comprises a rack rail 60 installed on the base 20 and a reset assembly 70 installed on the mechanism 40, and the rack rail 60 and the reset assembly 70 cooperate to provide power for the closing of the cover plate 30 and provide damping effect for the movement of the cover plate 30.

[0038] As shown in FIG. 2 , in the closing state, the operator applies a pushing force on the button 10 to push the cover plate 30 to open forward relative to the base 20. During the opening process, the operator needs to apply force on the button 10 all the time, that is, to apply a pushing force to start the closing state in the upper figure, to continuously apply a pushing force to the half-open state in the middle figure, and to continuously apply a pushing force to the fully open state in the lower figure until the limit position, and then to remove the applied force. As shown in FIG. 3 , during the opening process, the hook 50 enters the labyrinth 21 from the left side along the dotted line to enter the first stop slot 211, at which time the cover plate 30 cannot be pushed forward any more; after the hand is released, the hook 50 enters the check slot 213 upward along the dotted line under the action of the reset assembly 70.

[0039] As shown in FIG. 4 , in the fully open state, the operator applies a pushing force on the button 10 to push the cover plate 30 to open forward relative to the base 20 by a small distance, and then removes the applied force, so that the cover plate 30 can be automatically closed at a constant speed under the action of the reset assembly 70. Back to FIG. 3 ​​As shown, during the closing process, the front cover 30 is pushed to unlock the maze, causing the hook 50 to move to the lower right along the dotted line and enter the second stop groove 212. When the operator feels that the front cover 30 can no longer be pushed forward, he releases his hand, and the hook 50 exits the maze 21 from the right side along the dotted line.

[0040] like FIG. 5 As shown, mechanism 40 includes a connecting rod 41, two pull rods 42, two torsion springs 43, and two connecting rod shafts 44. Each pull rod 42 is rotatably mounted on the connecting rod 41 via a connecting rod shaft 44. Specifically, each connecting rod shaft 44 passes sequentially through a hole in the pull rod 42, a hole 411 in the connecting rod 41, a torsion spring 43, a hole 412 in the connecting rod 41, and a hole in the pull rod 42, thereby rotatably fixing the connecting rod 41, the connecting rod shaft 44, the torsion spring 43, and the pull rod 42.

[0041] like FIG. 5 As shown, the mechanism 40 also includes two cover plate pivots 47, wherein each pull rod 42 is rotatably mounted on the cover plate 30 via the cover plate pivots 47. Specifically, each cover plate pivot 47 passes sequentially through the hole of the pull rod 42, the bearing seat 301 of the cover plate 30, and the hole of the pull rod 42, thereby rotatably fixing the pull rod 42, the cover plate pivot 47, and the cover plate 30.

[0042] like FIG. 5 As shown, button 10 has a long rod-shaped structure, with its front end forming a push rod 11 having an arc segment 111 and a straight segment 112. FIG. 6 As shown, the sliding door mechanism also includes two return springs 80, one end of which is connected to structure 31 of the cover plate 30, and the other end is connected to structure 12 on the button 10. When the operator applies force to the button 10, the return springs 80 are stretched. After the operator releases the force, the return springs 80 contract, and the button 10 returns to its initial position relative to the cover plate 30. In addition, the button 10 also has a limiting post 13, such as... FIG. 6 As shown, the cover plate 30 also has a limiting seat 32, which cooperates with the limiting post 13.

[0043] Back FIG. 5 The mechanism 40 also includes four bushings 45, which are rotatably mounted on the bushing shafts 413 of the connecting rod 41. They are paired up and contact the push rod 11 of the button 10 to apply force to the connecting rod 41 via the button 10. The specific working method will be described below. FIG. 10 Provide a detailed description.

[0044] like FIG. 5 As shown, mechanism 40 also includes a connecting arm 46, which is rotatably mounted on connecting rod 41. FIG. 7 As shown, the reset assembly 70 is rotatably mounted on the connecting arm 46, so that the mechanism 40 and the reset assembly 70 are connected through the connecting arm 46 to transmit reset power.

[0045] likeFIGS. 8A-8B As shown, the reset assembly 70 comprises a vehicle body 71 and a coil spring 72, wherein the coil spring 72 is mounted in the vehicle body 71 in a rotatable manner through two side shaft structures to provide the force for closing the cover 30. Specifically, one end of the coil spring 72 is mounted in a coil spring limiting groove 711 of the vehicle body 71, and the other end is hung on the coil spring hook 601 of the rack rail 60 through a coil spring hanging hole 721.

[0046] As shown in the lower left of FIGS. 8A-8B , the reset assembly 70 further comprises two dampers 73, which are symmetrically mounted on the two sides of the vehicle body 71 and operate independently of each other. Specifically, each damper 73 is mounted on the vehicle body 71 through a buckle and engages with the rack 602 of the rack rail 60 to provide a damping effect.

[0047] In particular, referring back to FIG. 5 , the two sides of the connecting rod 41 have laterally protruding drop lock pins 414, and the two sides of the pull rod 42 have laterally protruding first shafts 421 (also referred to as variable rail shafts) and second shafts 422 (also referred to as translation shafts), which are respectively inserted into the tracks 22 (see FIG. 2 ) of the base 20 for cooperation. As shown in the lower right of FIG. 9 , the tracks 22 comprise variable rail grooves 221 and locking grooves 222, wherein the variable rail grooves 221 comprise a straight section and a vertical section extending upward from the straight section to accommodate the first shafts 421, and the locking grooves 222 extend downward from the variable rail grooves 221 in an arc shape at the end of the variable rail grooves 221 to accommodate the drop lock pins 414. In this embodiment, the depth of the locking grooves 222 is less than the depth of the variable rail grooves 221, thereby avoiding the drop lock pins 414 from jumping out of the tracks and ensuring smooth opening of the cover 30.

[0048] FIG. 10 The upper view of FIG. 11 shows the closed state, and the state of the cover 30 at this time corresponds to the upper view of FIG. 2 . In this state, the push rod 11 does not move relative to the shaft sleeve 45, and the drop lock pins 414 are in the locking grooves 222; the first shafts 421 are at the highest point of the vertical sections of the variable rail grooves 221; and the second shafts 422 are in the straight sections of the variable rail grooves 221.

[0049] FIG. 10 The upper view of FIG. 11 shows the unlocked state, and the state of the cover 30 at this time does not move in the unlocked state and still corresponds to the upper view of FIG. 2the upper figure. In this state, the circular arc segment 111 of the push rod 11 moves relative to the shaft sleeve 45, and the circular arc segment 111 acts on the connecting rod 41 during the unlocking process to make the connecting rod 41 rotate, while the pull rod 42 remains stationary, so that the locking pin 414 is lifted to disengage from the locking groove 222 with the second shaft 422 as the rotation axis; the first shaft 421 is still at the highest position of the vertical segment of the variable track groove 221, which also represents that the cover plate 30 has not moved; and the second shaft 422 is also at the linear segment of the variable track groove 221.

[0050] FIG. 10 and FIG. 11 the middle and lower figures show the state of the cover plate 30 after the variable track, which corresponds to FIG. 2 the middle figure. In this state, the straight segment 112 of the push rod 11 moves relative to the shaft sleeve 45, and the force F is transmitted to the connecting rod 41 through the push rod 11 to make the second shaft 422 move along the linear segment of the variable track groove 221, and the first shaft 421 is dragged to move along the linear segment of the variable track groove 221 through the pull rod 42, until the first shaft 421 moves from the vertical segment to the linear segment, completing the variable track.

[0051] FIG. 10 and FIG. 11 the lower figure shows the open state, and the state of the cover plate 30 at this time corresponds to FIG. 2 the lower figure. In this state, the straight segment of the push rod 11 is disengaged from the shaft sleeve 45, the limiting column 13 (see FIG. 5 ) is in contact with the limiting seat 32 (see FIG. 6 ), the force F is transmitted to the cover plate connecting rod 42 and the connecting rod 41 in turn through the limiting column 13, and the locking pin 414, the first shaft 421 and the second shaft 422 simultaneously form a stable movement state in the linear segment of the variable track groove 221, until the cover plate is completely opened.

[0052] Unlike the prior art, the present application solves the problem of pressing collapse by lifting the locking pin 414 to unlock through the push rod 11, as shown in FIG. 12 when the force F0 is applied to the first shaft 421 (the external force acts vertically downward on the tail of the cover plate), it is transmitted to the second shaft 422 through the connecting rod a (i.e. the pull rod 42) to generate a component force F1, and the second shaft 422 and the locking pin 414 are connected through the connecting rod b (due to the pull rod 42 installed on the connecting rod 41) to generate a component force F2, and the locking pin 414 cannot move due to the limitation of the locking groove 222 to avoid the tail pressing collapse. At the same time, since the connecting rod a and the connecting rod b can rotate around the second shaft 422 respectively, the connecting rod a and the connecting rod b are separated by the torsional spring 43 to assist the locking pin 414 to enter the locking groove 222 and to assist in avoiding the tail pressing collapse; at the same time, it also supports the reset of the cover plate 30 to ensure a good matching relationship with the surrounding parts. In this way, the present application can realize the zero-face-difference matching of the cover plate 30 and the surrounding parts, prevent the tail of the cover plate 30 from collapsing under the action of the positive pressure, and is more reliable than the prior art.
