Description
Technical Field
[0001] The present invention relates to the field of vehicle-mounted artificial intelligence interaction devices, and in particular to an artificial intelligence interaction device based on big data. Background Art
[0002] The existing vehicle-mounted mobile phone holder can be fixedly installed on the central control platform inside different vehicles, and the locking motor built into the vehicle-mounted mobile phone holder can automatically complete the clamping and locking work of the mobile phone. While ensuring the stable clamping effect of the mobile phone, it is convenient for the driver to quickly take and put the mobile phone. After the driver clamps the mobile phone on the vehicle-mounted mobile phone holder, the mobile phone can be placed at the same height of the driver's driving observation line of sight, providing navigation auxiliary information to the driver. However, once the mobile phone holder is installed and fixed in a fixed area in the car, the position of the mobile phone holder can no longer be moved and adjusted over a large range. When the installation position of the mobile phone holder is far away from the driver, it is difficult for the driver to operate and use the mobile phone on the vehicle-mounted mobile phone holder during the period of stopping driving. When the installation position of the mobile phone holder is close to the driver, the driver needs to switch his sight back and forth between the road and the mobile phone during driving, so he needs to frequently and significantly adjust the eye focus distance, which is not only not conducive to safe driving, but also easy to make the driver feel eye fatigue. Therefore, this solution provides an artificial intelligence interaction device based on big data for vehicle-mounted human interaction. Summary of the invention

[0021] like Figure 1-Figure 7 As shown, the mobile phone clamping frame assembly includes a fixed card plate 31, a telescopic card plate 32, a reset spring 33 and a locking assembly; the fixed card plate 31 is fixedly connected to the main connecting member 26; the telescopic card plate 32 is slidably connected to the fixed card plate 31; two reset springs 33 are fixedly connected between the telescopic card plate 32 and the fixed card plate 31, and the reset spring 33 is located inside the fixed card plate 31; a U-shaped clamping structure is respectively provided at the upper end of the fixed card plate 31 and the lower end of the telescopic card plate 32; the auxiliary connecting member 28 is rotatably connected to the fixed card plate 31; and the fixed card plate 31 is connected to a locking assembly for locking the telescopic card plate 32.
[0022] like Figure 1 As shown, a gesture recognition sensor 4 is mounted on the fixed card plate 31 , and the gesture recognition sensor 4 is electrically connected to the main control module 15 through a circuit system.
[0023] The present invention discloses an artificial intelligence interaction device based on big data, which is mainly composed of a slide bar 21, a telescopic swing arm 22 and a main micro electric push rod 23, and a moving unit for actively controlling the front and rear distance adjustment of a mobile phone clamping frame group. During use, the driver first fixes the clamping frame bar 11 on the vehicle central control platform through the anti-slip bar 111, and pushes the fixed slider 12 to slide along the left and right directions of the clamping frame bar 11 for lateral movement adjustment, so that the fixed slider 12 drives the mobile phone clamping frame group on the slide bar 21 to move closer to the driver's position, and at the same time, the swing mounting frame 14 rotates around the axis of the central rotating shaft 13 for angle rotation adjustment, so that the mounting frame 14 drives the mobile phone clamping frame group on the slide bar 21 to rotate closer to the driver's angle, and the driver then clamps the mobile phone between the fixed card plate 31 and the telescopic card plate 32 of the mobile phone clamping frame group, and uses the locking component to lock the mobile phone on the mobile phone clamping frame group. At this time, the mobile phone on the mobile phone clamping frame group is in a placement state deflected toward the driver's side, which is convenient for the driver to observe the navigation auxiliary information in the mobile phone on the mobile phone clamping frame group, and the adjusting moving unit is in a state as follows: Figure 1 In the retracted state shown, the mobile phone clamping frame assembly on the slide bar 21 is at the same height as the driver's driving observation line of sight and away from the driver's side, so that the driver can quickly and clearly observe the navigation assistance information provided on the mobile phone without having to drastically change the eye observation line of sight and drastically adjust the eye focusing distance during driving, thereby ensuring the driver's safe driving work.
[0024] After the driver connects the power data interface 151 of the general control module 15 to the power data connection port of the vehicle through the power data line, the general control module 15 can actively read and analyze the vehicle's driving big data, so that the general control module 15 can automatically determine the current driving state of the vehicle. At the same time, the gesture recognition sensor 4 on the mobile phone holder is in a state of deflection toward the driver's side. When the general control module 15 automatically determines that the vehicle is currently in a stopped driving state by analyzing the vehicle's driving big data, the gesture recognition sensor 4 is in an on state. At this time, the driver only needs to wave in front of the gesture recognition sensor 4. After actively recognizing the waving action, the gesture recognition sensor 4 will trigger the information through the circuit system The main control module 15 then feeds back the released signal to the adjustment moving unit, so that the main micro-electric push rod 23 pulls the telescopic swing arm 22 to rotate upward, and at the same time, the telescopic swing arm 22 pushes the slide bar 21 to move forward along the cylindrical slider 141, so that the slide bar 21 drives the mobile phone on the mobile phone clamping frame group to move closer to the driver, and at the same time, the telescopic swing arm 22 that rotates upward will shrink under the obstruction of the slide bar 21. When the telescopic swing arm 22 enters the last stage of shrinkage and can no longer shrink, the telescopic swing arm 22 that continues to rotate upward will push the slide bar 21 to rotate clockwise around the axis of the cylindrical slider 141 at a left viewing angle, so that the slide bar 21 drives the mobile phone on the mobile phone clamping frame group to rotate downward to reduce the height, and the adjustment moving unit is in the following state. Figure 8 In the released state shown, the mobile phone on the mobile phone clamping frame assembly can also move downward to approach the driver's hand during the forward movement. At the same time, the auxiliary micro-electric push rod 27 pulls the auxiliary connecting member 28 to drive the mobile phone clamping frame assembly and the main connecting member 26 to rotate counterclockwise around the connecting axis of the main connecting member 26 and the slide bar 21 at a left viewing angle, so that the mobile phone on the mobile phone clamping frame assembly remains in an upright state, which is convenient for the driver to control the mobile phone on the mobile phone clamping frame assembly.
[0025] After that, when the main control module 15 automatically determines that the vehicle is currently in the driving state by analyzing the vehicle's driving big data, the main control module 15 will feed back the retracted signal to the adjusting mobile unit, allowing the main micro-electric push rod 23 to push the telescopic swing arm 22 to rotate downward, and at the same time, the telescopic swing arm 22 pulls the slide bar 21 to move backward along the cylindrical slider 141 and rotate in the opposite direction to reset, allowing the slide bar 21 to drive the mobile phone on the mobile phone clamping frame assembly to move away from the driver and reset, and at the same time, the secondary micro-electric push rod 27 pushes the secondary connecting piece 28 to drive the mobile phone clamping frame assembly to rotate in the opposite direction to reset, so that the adjusting mobile unit is in the same state again. Figure 1The folded state shown achieves the safety purpose of indicating to the driver that he cannot continue to operate the mobile phone while driving and can only concentrate on driving. It realizes the adjustment of the distance of the mobile phone on the mobile phone clamping frame by a simple artificial intelligence interaction method under the condition of judging the driving state of the vehicle. It not only ensures the driver's safe driving work, but also facilitates the driver to operate the mobile phone when the vehicle is stopped. Example
[0026] On the basis of Example 1, Figure 1-Figure 7 As shown, the locking assembly of this embodiment includes a wedge-shaped rack 34, a wedge-shaped block 35 and an unlocking spring 36; a wedge-shaped rack 34 is fixedly connected to the telescopic card plate 32; a wedge-shaped block 35 is slidably connected to the fixed card plate 31 and is aligned with the upper and lower positions of the wedge-shaped rack 34, and the front side of the wedge-shaped block 35 protrudes forward from the surface of the fixed card plate 31; two unlocking springs 36 are fixedly connected between the wedge block 35 and the fixed card plate 31, and the unlocking spring 36 is located inside the fixed card plate 31; a sliding card strip 37 is slidably connected in each of the U-shaped clamping structures of the fixed card plate 31 and the telescopic card plate 32; the sliding card strips 37 are composed of a slider component made of plastic material and a card strip component made of rubber material, and the fixed card plate 31 and the telescopic card plate 32 are slidably connected to the plastic slider components of the corresponding sliding card strips 37 respectively; the sliding card strip 37 clamps the mobile phone through the rubber card strip component.
[0027] During use, after the driver places the bottom of the mobile phone on the sliding card strip 37 in the U-shaped holding structure of the fixed card plate 31, the driver presses the telescopic card plate 32 downward to drive the reset spring 33 to compress downward, and at the same time, the telescopic card plate 32 drives each tooth profile structure of the wedge-shaped rack 34 to pass through the wedge-shaped card block 35 downward in sequence, until the sliding card strip 37 in the U-shaped holding structure of the telescopic card plate 32 is clamped on the top of the mobile phone. At this time, the wedge-shaped card block 35 is clamped in the corresponding tooth profile structure of the wedge-shaped rack 34, so that the telescopic card plate 32 is firmly fixed on the fixed card plate 31 through the clamping structure between the wedge-shaped rack 34 and the wedge-shaped card block 35, completing the mobile phone clamping frame assembly. To lock the mobile phone clamp, you only need to press the mobile phone to drive the two sliding card strips 37 to move backward along the U-shaped clamping structure of the fixed card plate 31 and the U-shaped clamping structure of the telescopic card plate 32 respectively, so that the mobile phone pushes the wedge-shaped card block 35 to move backward along the fixed card plate 31 to leave the wedge-shaped rack 34, and at the same time, the wedge-shaped card block 35 drives the unlocking spring 36 to compress backward. At this time, the compressed reset spring 33 quickly pushes the telescopic card plate 32 along the fixed card plate 31 to drive the wedge-shaped rack 34 to reset upward. At the same time, the telescopic card plate 32 drives the sliding card strip 37 connected to it to move upward away from the top of the mobile phone, thereby completing the unlocking work of the mobile phone clamping by the mobile phone clamping assembly in one step.
[0028] Therefore, after the mobile phone clamping frame assembly completes the locking work of clamping the mobile phone, and the mobile phone clamping frame assembly is located in the Figure 1When the position is far away from the driver's side as shown, when the driver stops driving the vehicle, and when the main micro-electric push rod 23 pulls the telescopic swing arm 22 to drive the slide bar 21 to extend the mobile phone clamping frame assembly toward the driver, the driver only needs to hold the mobile phone in the mobile phone clamping frame assembly with one hand, so that the mobile phone no longer moves forward with the mobile phone clamping frame assembly. The action of pushing the mobile phone clamping frame assembly forward by the slide bar 21 can drive the wedge-shaped card block 35 forward to contact the mobile phone to complete the press-to-unlock, thereby easily completing the unlocking work of the mobile phone clamping frame assembly on the mobile phone. Example
[0029] On the basis of Example 1, Figure 1-Figure 7 As shown, the main connecting member 26 and the auxiliary connecting member 28 of this embodiment respectively use two spring shock absorbers of different sizes, and the slide bar 21 and the auxiliary micro electric push rod 27 are respectively non-rigidly connected to the fixed card plate 31 through the two spring shock absorbers, so that the two spring shock absorbers can absorb the vibration impact force transmitted from the slide bar 21 to the fixed card plate 31 during the driving of the vehicle, thereby greatly reducing the vibration of the mobile phone fixed and clamped between the fixed card plate 31 and the telescopic card plate 32, so that the driver can clearly observe the navigation screen of the mobile phone.
[0030] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
