Detailed Implementation

[0019] Example 1: This embodiment provides an automatic auxiliary opening and closing device for a car drawer storage box, such as... Figures 1-3 As shown, the device includes a lower support 12 and a drawer 1 slidably mounted on the lower support 12. A slider 8 is slidably mounted on the top of the lower support 12 along the sliding direction of the drawer 1. A clutch assembly is provided between the slider 8 and the bottom of the drawer 1. The clutch assembly engages the drawer 1 and the slider 8 during the process of the drawer 1 sliding from a half-closed state to a fully closed state and during the process of the drawer 1 opening from a fully closed state. A drawer drive device is provided on the lower support 12. The drawer drive device includes at least one first drive end moving in a first direction and at least one second drive end moving in a second direction. Both the first drive end and the second drive end are connected to the slider 8. A first micro switch 5 connected to the drawer drive device is provided on the top of the lower support 12. During the process of the drawer 1 moving from a half-closed state to a fully closed state, the first micro switch 5 is pressed down to conduct.

[0020] When drawer 1 is pulled or pushed manually, it slides on the lower support 12. The process of drawer 1 sliding in a first direction is the opening process, where the first direction refers to the direction in which drawer 1 slides away from the vehicle's drawer box. The process of drawer 1 sliding in a second direction is the closing process, where the second direction refers to the direction in which drawer 1 slides closer to the drawer box. The top of the lower support 12 is also equipped with a slider 8 that can slide relative to drawer 1. The slider 8 is driven by the first drive end of the drawer drive device to slide in the first direction, and by the second drive end of the drawer drive device to slide in the second direction.

[0021] During the closing process of drawer 1, that is, during the sliding of drawer 1 along the second direction, from the fully open state to the half-closed state, the clutch assembly will not engage with the bottom of drawer 1. In other words, during this process, drawer 1 is closed by manual pushing. When drawer 1 slides to any position between the half-closed and fully closed states under manual pushing, the clutch assembly engages with one end of the bottom of drawer 1, and simultaneously the first micro switch 5 is pressed down and activated to send a closing signal to the drawer drive device. At this time, the second drive end of the drawer drive device drives the slider 8 to slide along the second direction, which in turn drives drawer 1 to slide along the second direction, ultimately achieving automatic closing of drawer 1 to the fully closed state.

[0022] During the opening of drawer 1, that is, when drawer 1 slides from the fully closed state along the first direction, the clutch component engages with the other end of the bottom of drawer 1. At the same time, the external controller sends an opening signal to the drawer drive device. The first drive end of the drawer drive device drives the slider 8 to slide along the first direction, and then drives the drawer 1 to slide along the first direction through the slider 8, ultimately realizing the automatic opening of drawer 1.

[0023] Example 2: This embodiment discloses an automatic auxiliary opening and closing device for a car drawer storage box, which is an optimization based on Embodiment 1, such as... Figures 6-9 As shown, the clutch assembly includes a locking pin 2 and a clutch guide 3. One end of the clutch guide 3 is rotatably mounted on the top of the slider 8, and the locking pin 2 is mounted on the bottom of the drawer 1. The top of the clutch guide 3 is provided with a clutch inner cavity, and a protrusion is provided in the middle of the clutch inner cavity. One end of the clutch inner cavity is provided with a closing section slide groove 301. The end of the closing section slide groove 301 near the protrusion is connected to the clutch inner cavity, and the end of the closing section slide groove 301 away from the protrusion is closed. A concave arc surface 302 is provided on the side of the protrusion near the opening of the closing section slide groove 301, and a convex arc surface 303 facing the opposite direction to the concave arc surface 302 is provided on the side of the clutch inner cavity near the opening of the closing section slide groove 301.

[0024] Shutdown process: When drawer 1 is in any position between the fully open and partially closed states, the locking pin 2 at the bottom of drawer 1 is located inside the closing section slide groove 301 and slides along the closing section slide groove 301. The slider 8 is disengaged from the locking pin 2, and drawer 1 needs to be driven by external force to slide. When drawer 1 slides from the partially closed state to the fully closed state, that is, when drawer 1 slides in the second direction, the locking pin 2 disengages from the closing section slide groove 301 and engages with the concave arc surface 302. At the same time, the first micro switch 5 is pressed down and turned on. At this time, the drawer drive device drives the slider 8 to slide in the second direction, and then drives the drawer 1 to slide in the second direction through the structure of the concave arc surface 302 engaging with the locking pin 2, thereby realizing the automatic closing of drawer 1.

[0025] Startup process: When drawer 1 slides from the fully closed state to the open state, that is, when drawer 1 slides along the first direction, the locking pin 2 disengages from the concave arc surface 302 and engages with the convex arc surface 303. At the same time, the drawer drive device drives the slider 8 to slide along the first direction, and then the engagement structure between the locking pin 2 and the convex arc surface 303 drives the drawer 1 to slide along the first direction, thereby opening drawer 1.

[0026] Furthermore, a horn opening is provided at the end of the clutch inner cavity away from the closing section slide groove 301.

[0027] The rest of this embodiment is the same as that of Embodiment 1, so it will not be described again.

[0028] Example 3: This embodiment discloses an automatic auxiliary opening and closing device for a car drawer storage box, which is an optimization based on embodiment 1 or 2, such as... Figures 6-9 As shown, the end of the clutch guide 3 away from the closing section slide groove 301 is rotatably connected to the top of the slider 8 via a rotating shaft. The top of the slider 8 is provided with at least one set of arc-shaped guide grooves concentric with the rotating shaft, and the bottom of the clutch guide 3 is provided with a guide member that is slidably connected to the arc-shaped guide grooves.

[0029] When the locking pin 2 slides in the clutch cavity inside the clutch guide 3, once the locking pin 2 presses against the inner wall of the clutch cavity, it drives the clutch guide 3 to rotate around the pivot at a certain angle. At the same time, through the cooperation of the arc-shaped guide groove and the guide, the clutch guide 3 is ensured to rotate at a certain angle according to the preset circumferential path. The rotation of the clutch guide 3 ensures that the locking pin 2 can accurately and smoothly engage with the concave arc surface 302 or the convex arc surface 303.

[0030] The rest of this embodiment is the same as that of embodiment 1 or 2, so it will not be described again.

[0031] Example 4: This embodiment discloses an automatic auxiliary opening and closing device for a car drawer storage box, which is optimized based on any one of embodiments 1-3, such as... Figure 7 As shown, the bottom of the clutch guide 3 is provided with a protruding structure 304, and the top of the lower bracket 12 is provided with a second micro switch 4. The protruding structure 304 can press down the second micro switch 4 when the drawer 1 is in a fully closed state. The bottom of the drawer 1 is provided with a rib structure 102, and the top of the lower bracket 12 is provided with a first micro switch 5. The rib structure 102 can press down the first micro switch 5 during the stroke from half-closed to fully closed of the drawer 1. The first micro switch 5 is connected to the drawer drive device.

[0032] The bottom of the clutch guide 3 is connected by bolts or welded to a raised structure 304, which includes a raised pressure strip. When the drawer 1 slides to the fully closed state under the action of the slider 8, the raised structure 304 at the bottom of the clutch guide 3 presses down the second micro switch 4. The second micro switch 4 is pressed down to detect whether the drawer 1 is in the correct position. The second micro switch 4 will only be pressed down when the drawer 1 has slid into place. It can be determined that the drawer 1 has slid into place after both the first micro switch 5 and the second micro switch 4 are pressed down and connected.

[0033] like Figure 10 As shown, the bottom of drawer 1 is connected by bolts or welded with a raised rib structure 102. When drawer 1 is in any position between the half-closed and fully-closed states (including the end position), the raised rib structure 102 presses down the first micro switch 5, which in turn sends a closing signal to the drawer drive device through the signal circuit of the first micro switch 5. This causes the drawer drive device to drive the slider 8 to slide in the second direction, and then the clutch assembly on the slider 8, after being engaged, drives the drawer 1 to slide in the second direction to the fully closed state. That is, under manual operation, as long as drawer 1 is closed to any position between the half-closed and fully-closed states, the drawer drive device can be activated to drive drawer 1 to close automatically, thereby avoiding the situation where drawer 1 is not fully closed.

[0034] The rest of this embodiment is the same as any one of embodiments 1-3, so it will not be described again.

[0035] Example 5: This embodiment discloses an automatic auxiliary opening and closing device for a car drawer storage box, which is optimized based on any one of embodiments 1-4, such as... Figures 1-3As shown, parallel slide rails 11 are arranged on both sides of the top of the lower support 12, and the bottom of the drawer 1 is slidably connected to the slide rails 11. A damping engagement device is provided on one side of the slide rails 11 on the lower support 12, and the damping engagement device is dampingly engaged with the bottom of the drawer 1. The damping engagement device includes a damper 6, a gear 101A, and a rack 101B. The rack 101B is located at the bottom of the drawer 1, and the damper 6 is located on one side of the slide rails 11. The gear 101A is sleeved on the damping shaft of the damper 6, and the gear 101A is engaged with the rack 101B.

[0036] During the opening or closing of drawer 1, the rack 101B at the bottom of drawer 1 is always engaged with gear 101A, and the rotational damping provided by the damping shaft ensures the tight engagement between rack 101B and gear 101A, thereby preventing drawer 1 from becoming loose during opening or closing.

[0037] The rest of this embodiment is the same as any one of embodiments 1-4, so it will not be described again.

[0038] Example 6: This embodiment discloses an automatic auxiliary opening and closing device for a car drawer storage box, which is optimized based on any one of embodiments 1-5, such as... Figures 3-5 As shown, the drawer drive device includes a reversing wheel 10, a first wire rope 13, a second wire rope 14, a motor 15, and a winding wheel 17. The reversing wheel 10 is rotatably mounted at the first end of the top of the lower support 12, and the winding wheel 17 is rotatably mounted at the second end of the top of the lower support 12. The first end of the first wire rope 13 is connected to the first end of the slider 8, and the second end of the first wire rope 13 passes around the reversing wheel 10 and is wound on the winding wheel 17. The first end of the second wire rope 14 is connected to the second end of the slider 8, and the second end of the second wire rope 14 is wound on the winding wheel 17. The axle of the winding wheel 17 is connected to the output shaft of the motor 15.

[0039] It should be noted that a Hall sensor is coupled to the output shaft of motor 15 to detect the number of rotations of the output shaft. After the first microswitch 5 is triggered and sends a shutdown signal to motor 15, motor 15 rotates according to the set number of rotations, driving the winding wheel 17 and the reversing wheel 10 to rotate a predetermined number of times, just enough to make drawer 1 slide to the fully closed state. After the Hall sensor detects that the output shaft of motor 15 has rotated a predetermined number of times, it controls motor 15 to stop, so that drawer 1 is in the fully closed state.

[0040] Specifically: When the drawer is closed, the motor 1 drives the winding wheel 17 to reverse. At this time, the winding wheel 17 winds the second steel wire rope 14, and at the same time, the winding wheel 17 releases the first steel wire rope 13 to pull the slider 8 to slide in the second direction. Then, the clutch guide 3 on the slider 8 engages with the locking pin 2 at the bottom of the drawer 1, driving the drawer 1 to slide in the second direction, and finally driving the drawer 1 to close automatically.

[0041] When the drawer is opened, the motor 1 drives the winding wheel 17 to rotate forward. At this time, the winding wheel 17 releases the second steel wire rope 14. At the same time, the winding wheel 17, together with the reversing wheel 10, pulls the first steel wire rope 13 in the first direction, causing the slider 8 to slide in the first direction. Then, the clutch guide 3 on the slider 8 engages with the locking pin 2 at the bottom of the drawer 1, causing the drawer 1 to slide in the first direction, and finally opening the drawer 1.

[0042] Furthermore, a first die-casting head 1301 is provided at the bottom first end of the slider 8. The first die-casting head 1301 is provided with a first slot. The first end of the first wire rope 13 is provided with a first locking head 1302 that engages with the first slot. A first pre-tensioning spring 1303 is sleeved on the outside of the first wire rope 13. The first pre-tensioning spring 1303 abuts against the first die-casting head 1301 and tightens the first end of the first wire rope 13. When the first wire rope 13 is pulled in the first direction, the first locking head 1302 engages with the first slot on the first die-casting head 1301, thereby driving the slider 8 to slide in the first direction, so that one end of the guide groove 3 engages with the locking pin 2 to drive the drawer 1 to slide open in the first direction.

[0043] Furthermore, a second die-casting head 1401 is provided at the second end of the bottom of the slider 8. The second die-casting head 1401 has a second slot. The first end of the second wire rope 14 has a second locking head 1402 that engages with the second slot. A second pre-tensioning spring 1403 is sleeved on the outside of the second wire rope 14. The second pre-tensioning spring 1403 abuts against the second die-casting head 1401 and tightens the first end of the second wire rope 14. When the second wire rope 14 is pulled along the second direction, the second locking head 1402 engages with the second slot on the second die-casting head 1401, thereby causing the slider 8 to slide along the second direction. This causes the other end of the guide groove 3 to engage with the locking pin 2, thereby causing the drawer 1 to slide and close along the second direction.

[0044] Furthermore, a motor bracket 18 is provided on one side of the slider 8, the motor 15 is fixedly mounted on the motor bracket 18, and a rear bracket 16 is provided at the end of the lower bracket 12 near the motor 15.

[0045] Furthermore, a first buffer pad 9 is provided at the top first end of the lower support 12, and a second buffer pad 7 is provided at the top second end of the lower support 12. The slider 8 is located between the first buffer pad 9 and the second buffer pad 7. By setting the first buffer pad 9 and the second buffer pad 7, when the slider 8 slides to its limit position along the first direction or along the second direction, the first buffer pad 9 and the second buffer pad 7 buffer and limit the slider 8, preventing the slider 8 from continuing to slide.

[0046] The rest of this embodiment is the same as any one of embodiments 1-5, so it will not be described again.

[0047] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Any simple modifications or equivalent changes made to the above embodiments based on the technical essence of the present invention shall fall within the protection scope of the present invention.
