Description

Technical Field

[0001] This utility model belongs to the technical field of automotive storage box opening and closing mechanisms, specifically relating to an auxiliary closing mechanism for automotive drawer storage boxes. Background Technology

[0002] With the popularization of the four new trends in automobiles, the functional components in the car cabin are beginning to develop towards intelligence and electrification, thereby providing consumers with a more intelligent and convenient user experience.

[0003] Existing automotive cabin drawer products require manual closing. If the drawer is not pushed all the way down, it may not be fully closed, resulting in a "half-closed" situation. This can cause the drawer to open automatically due to vibrations while driving, leading to items falling out. Furthermore, the mechanical collision of the traditional manual drawer closing mechanism generates considerable noise, which is detrimental to the quietness of the car cabin.

[0004] Therefore, in view of the above-mentioned problems of existing vehicle-mounted manual drawer closing structures, this utility model discloses an auxiliary closing mechanism for automotive drawer storage boxes. Utility Model Content

Detailed Implementation

[0018] Example 1: This embodiment provides an auxiliary closing mechanism for a car drawer storage box, such as... Figures 1-3As shown, the device includes a lower support 12 and a drawer 1 slidably mounted on the lower support 12. The bottom of the drawer 1 is provided with a locking pin 2, and the top of the lower support 12 is provided with a guide groove 3. The locking pin 2 and the guide groove 3 are slidably connected. A drawer drive device is provided on one side of the lower support 12. The drawer drive device includes at least one first drive end that moves in a first direction and at least one second drive end that moves in a second direction. Both the first drive end and the second drive end are connected to the bottom of the drawer 1. 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.

[0019] It should be noted that, for the sake of clarity in demonstrating the structure, [the following text is missing]. Figure 1 Drawer 1 in the picture is shown upside down.

[0020] When drawer 1 is manually closed to a position between half-closed and fully closed in the second direction, the first microswitch 5 is pressed down and activated to send a closing signal to the drawer drive mechanism. Upon receiving the closing signal, the second drive end of the drawer drive mechanism is activated to drive the drawer 1 to slide in the second direction until drawer 1 is fully closed, at which point the drawer drive mechanism stops. To open the drawer, an opening signal is sent to the drawer drive mechanism, at which point the first drive end of the drawer drive mechanism is activated to drive drawer 1 to slide in the first direction, thus opening the drawer. During the sliding of drawer 1, the locking pin 2 slides along the guide groove 3 to guide the sliding of drawer 1, ensuring smooth opening and closing of drawer 1.

[0021] With the above settings, during the process of closing drawer 1, as long as drawer 1 is pushed to any position between the half-closed state and the fully closed state by human force, the first micro switch 5 can be triggered, thereby controlling the drawer drive device to assist in automatically and fully closing the drawer.

[0022] Example 2: This embodiment discloses an auxiliary closing mechanism for a car drawer storage box, which is an optimization based on Embodiment 1, such as... Figures 2-4 As shown, the drawer drive device includes a reversing wheel 10, a first steel wire rope 13, a second steel wire rope 14, a motor 15, and a winding wheel 17. The reversing wheel 10 is rotatably mounted on the top of the lower support 12 at a first end, and the winding wheel 17 is rotatably mounted on the top of the lower support 12 at a second end. The first end of the first steel wire rope 13 is connected to the bottom of the drawer 1 at a first end, and the second end of the first steel wire rope 13 passes around the reversing wheel 10 and is wound on the winding wheel 17. The first end of the second steel wire rope 14 is connected to the bottom of the drawer 1 at a second end, and the second end of the second steel 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.

[0023] 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.

[0024] 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 to pull the drawer 1 to slide in the second direction. At the same time, the winding wheel 17 releases the first steel wire rope 13 to avoid affecting the sliding of the drawer 1 in the second direction, thereby driving the drawer 1 to close automatically.

[0025] When the drawer is opened, the motor 1 drives the winding wheel 17 to rotate clockwise. At this time, the winding wheel 17 releases the second steel wire rope 14 to avoid affecting the sliding of the drawer 1 in the first direction. At the same time, the winding wheel 17, in conjunction with the reversing wheel 10, pulls the first steel wire rope 13 in the first direction, thereby driving the drawer 1 to slide in the first direction and thus opening the drawer 1.

[0026] Furthermore, the lower support 12 has parallel slide rails 11 on both sides of its top, and the bottom of the drawer 1 is slidably connected to the slide rails 11. The bottom of the guide groove 3 is provided with a slider 8, which is connected to the first end of the first steel wire rope 13 and the first end of the second steel wire rope 14. When the drawer 1 is manually pushed from the fully open state to the half-closed state, the drawer 1 slides smoothly along the slide rails 11 under the action of the manual force until the drawer 1 slides to the half-closed state. At this time, the first micro switch 5 is triggered, the motor 1 drives the winding wheel 17 to reverse, and pulls the slider 8 and the guide groove 3 in the second direction through the second steel wire rope 14. At this time, one end of the guide groove 3 is engaged with the locking pin 2 at the bottom of the drawer 1, and then the slider 8 and the guide groove 3 drive the drawer 1 to automatically slide from the half-closed state to the fully closed state, thereby realizing the automatic closing of the drawer 1.

[0027] 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.

[0028] 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.

[0029] Furthermore, a motor bracket 18 is provided on one side of the slider 8, and the motor 15 is fixedly mounted on the motor bracket 18.

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

[0031] Example 3: This embodiment discloses an auxiliary closing mechanism for a car drawer storage box, which is an optimization based on embodiment 1 or 2, such as... Figure 6 As shown, the bottom of the drawer 1 is provided with a raised rib structure 102, and the top of the lower support 12 is provided with a first micro switch 5. The raised rib structure 102 can press down the first micro switch 5 during the drawer 1's stroke from half-closed to fully closed. The first micro switch 5 is connected to the drawer drive device. Figure 5 As shown, a protruding structure 304 is provided at the bottom of the guide groove 3, and a second micro switch 4 is provided at the top of the lower bracket 12. The protruding structure 304 can press down the second micro switch 4 when the drawer 1 is in a fully closed state.

[0032] When drawer 1 is in any position between the half-closed state and the fully closed state, the protruding rib structure 102 presses down the first micro switch 5, thereby sending a closing signal to the drawer drive device, which then drives drawer 1 to close automatically.

[0033] The purpose of setting up the second micro switch 4 is to indicate that the drawer 1 has moved into place when the first micro switch 5 and the second micro switch 4 are pressed down and turned on. If the second micro switch 4 is not pressed down and turned on, it indicates that the drawer 1 is not in place.

[0034] The rest of this embodiment is the same as that of embodiment 1 or 2, so it will not be described again.
