Description

Technical Field

[0001] The utility model relates to the technical field of automobile accessories, in particular to an unlocking mechanism for storing an automobile table top. Background Art

[0002] As people's demands for more efficient in-car space utilization continue to rise, vehicle interior design is becoming increasingly multifunctional and user-friendly. In modern automotive design, tabletops are becoming an essential component in enhancing the in-car experience.

[0072] Combine Figures 1 to 16 As shown, an unlocking mechanism for storing a car table top includes a mounting frame 1, a table top assembly 2, a drive limit assembly 3 and a first touch button 4.

[0073] The table top assembly 2 is slidably arranged in the installation frame 1; the drive limit assembly 3 is arranged in the installation frame 1 and is transmission-connected to the table top assembly 2, and is used to drive the table top assembly 2 to unfold or fold and then move back into the installation frame 1, and to limit it during use; the first touch button 4 is arranged on one side of the installation frame 1, and is electrically connected to the drive limit assembly 3, and is used to transmit a start signal thereto and control the movement of the table top assembly 2.

[0074] Among them, by arranging a driving limit component 3 in the installation frame 1, under the action of the driving limit component 3, not only can the table board component 2 be driven to slide on the installation frame 1, so that the table board component 2 can be unfolded and used according to actual needs, or placed in the inner cavity of the installation frame 1 for storage after folding, but the driving limit component 3 can also limit its table board component 2 to form a self-locking and unlocking structure, preventing the table board component 2 from moving easily due to external force, thereby improving the safety of passengers; the start signal is transmitted to the driving limit component 3 by the first touch button 4, thereby realizing the electric control of the table board component 2, making the operation of the table board component 2 more intelligent and reducing the inconvenience of manual operation.

[0075] Combine Figure 3 and Figure 4As shown, the drive limit assembly 3 includes: a first mounting block 31, a second mounting block 32, a drive motor 33, a drive screw 34, and a slider 35. The first mounting block 31 is located on one side of the mounting frame 1; the second mounting block 32 is located on the other side of the mounting frame 1; the drive motor 33 is located on one side of the second mounting block 32; the drive screw 34 is rotatably located between the first mounting block 31 and the second mounting block 32, with one end of the drive screw 34 passing through the second mounting block 32 and connected to the output end of the drive motor 33; and the slider 35 is sleeved on the drive screw 34.

[0076] Among them, when the table top assembly 2 needs to be moved to the outside of the installation frame 1 for unfolding and use, it is only necessary to press the first touch button 4. The first touch button 4 sends a start signal to the drive motor 33. After receiving the signal, the drive motor 33 starts to rotate, driving the drive screw 34 to rotate. The rotation of the drive screw 34 cooperates with the slider 35 through the thread, so that the slider 35 moves along the axial direction of the drive screw 34. The movement of the slider 35 drives the table top assembly 2 to slide out of the installation frame 1, and the table top assembly 2 can be unfolded and used. Because the self-locking structure is formed under the action of the drive motor 33, it is prevented that the external thrust can easily push the table top assembly 2 to move.

[0077] When the table top assembly 2 needs to be retracted into the installation frame 1 for storage, the user presses the first touch button again, driving the motor 33 to rotate in the reverse direction, driving the drive screw 34 to rotate in the reverse direction, and the reverse rotation of the drive screw 34 causes the slider 35 to move in the reverse direction along the axial direction of the drive screw 34. The movement of the slider 35 drives the table top assembly 2 to slide in from outside the installation frame 1 until it is fully retracted and locked in the installation frame 1.

[0078] Combine Figure 1 、 Figure 2 、 Figure 4 、 Figure 5 and Figure 6 As shown, a tabletop assembly 2 is mounted on the slider 35. The tabletop assembly 2 includes a base 21, a first rotating arm 22, a rotating bracket 23, a reinforcing support frame 24, a second rotating arm 25, a mounting plate 26, a tabletop bracket 27, a suspension hinge 28, and a tabletop body 29. The base 21 is connected to the slider 35 via screws; the first rotating arm 22 is rotatably mounted on the base 21; the rotating bracket 23 is rotatably mounted on the first rotating arm 22; the reinforcing support frame 24 is rotatably mounted between the first rotating arm 22 and the rotating bracket 23; the second rotating arm 25 is rotatably mounted on the rotating bracket 23; the mounting plate 26 is mounted on top of the second rotating arm 25; the tabletop bracket 27 is mounted on top of the mounting plate 26; and the tabletop body 29 is hingedly connected to both sides of the tabletop bracket 27 via suspension hinges 28.

[0079] Among them, when it is necessary to move the table board assembly 2 to the outside of the installation frame 1 for unfolding and use, it is only necessary to press the first touch button 4. The first touch button 4 sends a start signal to the drive motor 33. After receiving the signal, the drive motor 33 starts to rotate, driving the drive screw 34 to rotate. The rotation of the drive screw 34 cooperates with the slider 35 through the thread, so that the slider 35 moves along the axial direction of the drive screw 34. The movement of the slider 35 drives the entire table board assembly 2 to move to the outside of the installation frame 1, and then adjusts the angle of the first rotating arm 22. Then, the rotating bracket 23 is pulled to rotate relative to the first rotating arm 22, so that after the first rotating arm 22 rotates, it can be aligned with the first rotating arm 22 and the rotating bracket. 23 and the reinforced support frame 24 form a stable triangular structure, and finally by adjusting the angle of the table top bracket 27, the corresponding table top body 29 can be unfolded for use through the hovering hinge 28; after the entire table top assembly 2 needs to be folded, it is moved to the inside of the installation frame 1 for storage. It is only necessary to follow the above-mentioned opposite actions to complete the folding of the table top assembly 2. Secondly, press the first touch button 4. The first touch button 4 drives the drive motor 33 to rotate in the opposite direction, driving the drive screw 34 to rotate in the opposite direction. The reverse rotation of the drive screw 34 causes the slider 35 to move in the opposite direction along the axial direction of the drive screw 34. The movement of the slider 35 drives the entire table top assembly 2 to slide in from the outside of the installation frame 1 until it is fully retracted and locked in the installation frame 1.

[0080] Combine Figure 11 and Figure 12 As shown, a positioning groove 211 is formed at the lower portion of the base 21, and a positioning portion 351 is provided at the upper portion of the slider 35. The positioning portion 351 is embedded in the positioning groove 211. This ensures precise alignment between the base 21 and the slider 35, allowing the table top assembly 2 to maintain a stable and accurate position during the sliding process. The cooperation between the positioning groove 211 and the positioning portion 351 ensures the correct installation position of the base 21 on the slider 35, preventing the base 21 from shifting or misaligning during the sliding process.

[0081] Combine Figure 3 、 Figure 6 and Figure 11 As shown, guide portions 212 are fixedly provided on both sides of the base 21, and guide rods 11 are provided on both sides of the interior of the mounting frame 1. The guide portions 212 are slidably mounted on the guide rods 11. The cooperation between the guide portions 212 and the guide rods 11 forms a stable sliding path, allowing the base 21 to move along a predetermined trajectory during sliding, avoiding jamming caused by offset or skew.

[0082] Combine Figure 6 、 Figure 8 and Figure 13As shown, a first limiting groove 221 is provided on the first rotating arm 22, and a first limiting component 213 is also provided on one side of the base 21. The first limiting component 213 is embedded in the first limiting groove 221. The first limiting component 213 includes: a first limiting plate 2131, a first limiting column 2132 and a first limiting pin 2133. The first limiting column 2132 is provided on one side of the first limiting plate 2131; the first limiting pin 2133 is provided on one side of the first limiting column 2132, and the first limiting pin 2133 is embedded in the first limiting groove 221.

[0083] When the angle of the first rotating arm 22 is adjusted, the first limiting pin 2133 and the first limiting groove 221 act in combination to prevent the first rotating arm 22 from being easily pulled to rotate.

[0084] Combine Figure 9 and Figure 10 As shown, a second limiting pin 231 is provided on the upper portion of the rotating bracket 23 , and limiting bars 261 are provided on both sides of the mounting plate 26 , and the second limiting pin 231 is in contact with the limiting bars 261 .

[0085] Here, under the combined action of the second limiting pin 231 and the limiting strip 261 , the table support 27 is limited to be able to rotate only 180°.

[0086] Combine Figure 3 、 Figure 5 、 Figure 7 and Figure 14 As shown, a second limiting groove 222 with an arc-shaped structure is provided at the lower part of the first rotating arm 22, and a second limiting component 5 is provided at the bottom of the installation frame 1 on the side where the table board component 2 enters and exits. The second limiting component 5 is embedded in the second limiting groove 222. The second limiting component 5 includes: a third mounting block 51, a mounting tube 52, a sealing cover 53, a third limiting pin 54, a second limiting plate 55, a second limiting column 56 and a limiting spring 57. The third mounting block 51 is fixedly mounted on the lower part of the mounting frame 1 by means of screws; the mounting tube 52 is arranged on the third mounting block 51; the sealing cover 53 is arranged at the lower part of the third mounting block 51; the third limiting pin 54 is arranged in the mounting tube 52, and the top end of the third limiting pin 54 passes through the mounting tube 52 and is embedded in the second limiting groove 222, the bottom end of the third limiting pin 54 passes through the sealing cover 53 and extends to the outside of the sealing cover 53; the second limiting plate 55 is sleeved on the third limiting pin 54, and the second limiting plate 55 is located in the mounting tube 52; the second limiting column 56 is arranged at the lower part of the second limiting plate 55; the limiting spring 57 is sleeved on the second limiting column 56, the top end of the limiting spring 57 abuts against the second limiting plate 55, and the bottom end of the limiting spring 57 abuts against the sealing cover 53.

[0087] Among them, under the combined action of the second limit component 5 and the drive limit component 3, a double protection effect is formed, and elastic limitation is provided by the limit spring 57 to ensure that the third limit pin 54 is always close to the second limit groove 222, thereby improving the reliability and stability of the limitation. When the table board assembly 2 is unfolded or retracted, the drive limit component 3 and the second limit component 5 work together to ensure that the table board assembly 2 moves within a predetermined range, preventing accidental movement due to external force or improper operation, and improving the reliability and safety of the overall system.

[0088] Buffer pins 214 are provided on both sides of the base 21 , so that under the action of the buffer pins 214 , the base 21 is prevented from colliding with the installation frame 1 during the movement.

[0089] Combine Figure 2 、 Figure 15 and Figure 16 As shown, the mounting frame 1 is provided with a card assembly 6, which includes: a first card plate 61, a second card plate 62, a third card plate 63, a flip cover assembly 64, a first driving member 65, and a second touch button 66.

The second touch button 66 is provided on one side of the second card plate 62, and the second touch button 66 is electrically connected to the first driving member 65.

[0090] The first driving member 65 is a micro-gear motor. Limiting posts 621 are provided on both sides of the second snap plate 62. The flip cover assembly 64 is rotatably mounted on the limiting posts 621. The flip cover assembly 64 includes a rotating rod 641, a cover body 642, and meshing teeth 643. The rotating rod 641 is rotatably mounted on the limiting posts 621. The cover body 642 is located between the two rotating rods 641. The cover body 642 is located on one side of the second snap plate 62. The meshing teeth 643 are provided on the rotating rod 641 and mesh with the first driving member 65. A limiting box 622 is provided on one side of the second snap plate 62. A limiting bar 644 is provided on one of the rotating rods 641. The limiting bar 644 is embedded in the limiting box 622.

[0091] Opening process:

[0092] The user presses the second touch button 66 to send a start signal to the first drive member 65. After receiving the signal, the first drive member 65 starts to rotate and drives the rotating rod 641 to rotate through the meshing teeth 643. The rotation of the rotating rod 641 drives the cover body 642 to open, exposing the entry and exit channel of the table board assembly 2. The limit bar 644 slides in the limit box 622 to ensure the stability and accuracy of the cover body 642.

[0093] Shutdown process:

[0094] The user presses the second touch button 66 again to send a closing signal to the first driving member 65. The first driving member 65 rotates in the opposite direction, driving the rotating rod 641 to rotate in the opposite direction through the meshing teeth 643. The reverse rotation of the rotating rod 641 drives the cover body 642 to close, blocking the entry and exit channels of the table board assembly 2. The limit bar 644 slides in the limit box 622 to ensure the stability and accuracy of the cover body 642.

[0095] The working mode of the utility model is as follows:

[0096] Deployment of table top components:

[0097] The user presses the second touch button 66 to send a start signal to the first drive member 65. The first drive member 65 starts to rotate after receiving the signal, and drives the rotating rod 641 to rotate through the meshing teeth 643. The rotation of the rotating rod 641 drives the cover body 642 to open, exposing the entry and exit channel of the table top assembly 2. The user presses the first touch button 4 on the side of the installation frame 1. The first touch button 4 sends a start signal to the drive motor 33. The drive motor 33 starts to rotate forward after receiving the signal, driving the drive screw 34 to rotate. The rotation of the drive screw 34 is coordinated with the slider 35 through the thread, so that the slider 35 moves forward along the axial direction of the drive screw 34. The movement of the slider 35 drives the table top assembly 2 to slide out of the installation frame 1 until the table top assembly 2 is completely extended out of the installation frame 1. The user can manually adjust the angle of the first rotating arm 22, and then pull the rotating bracket 23 to form a stable triangular structure with the first rotating arm 22 and the reinforcing support frame 24. Finally, by adjusting the angle of the table top bracket 27 and using the hovering hinge 28 to unfold the table top body 29 to the desired position, after the table top assembly 2 is unfolded, the first limiting assembly 213 and the second limiting assembly 5 work together to ensure that the table top assembly 2 remains stable during use and prevents it from moving easily due to external forces.

[0098] Storage of table components:

[0099] The user manually folds the table top body 29 and retracts it into the table top bracket 27 via the hovering hinge 28. Then, the rotating bracket 23 and the first rotating arm 22 are reset to their initial state. The user presses the first touch button 4 again to send a closing signal to the drive motor 33. After receiving the signal, the drive motor 33 begins to reverse, driving the drive screw 34 to rotate in the opposite direction. The reverse rotation of the drive screw 34 causes the slider 35 to move backward along the axial direction of the drive screw 34. The movement of the slider 35 drives the table top assembly 2 to slide from outside the mounting frame 1 until it is fully retracted and locked in the mounting frame 1. The user presses the second touch button 66 again to send a closing signal to the first driving member 65. The first driving member 65 rotates in the opposite direction, driving the rotating rod 641 to rotate in the opposite direction through the meshing teeth 643. The reverse rotation of the rotating rod 641 drives the cover body 642 to close, blocking the entry and exit channel of the table top assembly 2.
