Description

Technical Field

[0001] The invention relates to the field of instrument panel table tops, in particular to an instrument panel table top with adjustable height. Background Art

[0002] A sub-dashboard is set between the driver's seat and the front passenger seat of the car. In order to increase the functionality of the car, some common daily necessities such as tissues and certificates are placed inside the sub-dashboard. As the pace of life becomes faster, some people choose to eat or work in the car, so a folding table is set inside the dashboard for easy use of the driver's seat or the front passenger seat.

[0003] Existing dashboard table tops, such as the auxiliary dashboard proposed in patent application number "CN201810602210.6", have a main table top and multiple sets of auxiliary table tops in the table top assembly that can be rotated and unfolded. When unfolded, the table top assembly can serve as a table top for users to use, and when folded, it can serve as an armrest and can be moved forward and backward to adjust to the optimal usage distance as needed.

[0004] However, the height of the existing instrument panel table cannot be adjusted, and it only has folding and extension functions. The height between the table panel and the seat is fixed. When a taller person sits on the seat and uses the table panel, the height of the table panel is low, and uncomfortable use may easily cause back pain. When a shorter person sits on the seat and uses the table panel, the high table panel may cause fatigue from lifting the arms. The non-adjustable height of the table panel results in a smaller range of applicable people and poor applicability. In addition, the table panel of the prior art is more protruding after being folded and stored, which reduces the aesthetics of the instrument panel and increases the chance of the driver's arm being bumped, resulting in low safety performance. Therefore, an instrument panel with adjustable height is proposed. Summary of the invention

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] A height-adjustable instrument panel, such as Figure 1-Figure 9 As shown, it includes a box body 1, which is installed between the main driver's seat and the co-driver's seat. An axle seat 3 is fixedly connected inside the box body 1. Two groups of electric push rods 4 (model YMD-603) are rotatably connected to the axle seat 3. The electric push rods 4 rotate on the axle seat 3 with a certain damping feeling, which increases the user's adjustment feel. The ends of the two groups of electric push rods 4 are commonly fixed with a connecting frame 13, and the connecting frame 13 is U-shaped. The end of the connecting frame 13 is rotatably connected to a connecting seat 12. A desktop 5 with an adjustable area is fixedly connected to the connecting seat 12. The desktop 5 relies on the connecting seat 12 to adjust the angle on the connecting frame 13. The connecting frame 13 is rotatably connected with a locking connection. The locking component of the seat 12 angle allows the desktop 5 to be locked after the angle is adjusted to maintain the desktop 5 stable. One end of the box body 1 is rotatably connected to a cover plate 6 for covering the box body 1. The cover plate 6 is L-shaped. The short side of the cover plate 6 is located on the side of the box body 1, and the long side is covered on the upper end of the box body 1. The end of the cover plate 6 is supported and matched with the lower end of the desktop 5. The cover plate 6 can not only be used to close the upper end of the box body 1, but also increase the load-bearing stability of the desktop 5 structure. The electric push rod 4 and the cover plate 6 form two sets of legs for the desktop 5 to support and stabilize the desktop 5. One side of the cover plate 6 is rotatably connected to a support component for controlling the inclination of the cover plate 6, and the end of the support component is snap-fitted with the inner wall of the box body 1.

[0033] When the table top 5 is stored in the box body 1, the cover plate 6 is covered on the box body 1, and items can be placed on the upper end of the cover plate 6. When the table top 5 is in use, the cover plate 6 is opened, the electric push rod 4 is rotated, and the electric push rod 4 is electrically driven to run. The output end of the electric push rod extends to a certain extent and stops, the table top 5 is rotated, the position and angle of the table top 5 are adjusted, the locking component is tightened, and the cover plate 6 is abutted against the specified position of the lower end of the table top 5, and the cover plate 6 is fixed by the supporting component. At this time, the table top 5 is installed. By controlling the locking component to loosen, the angle of the electric push rod 4 is adjusted. When the electric push rod 4 is in a vertical state, the height of the table top 5 is the highest. The angle of the electric push rod 4 is adjusted within a certain range, and the angle between the table top 5 and the electric push rod 4 is correspondingly adjusted to keep the table top 5 stable. The locking component fixes the angle, and then the angle of the cover plate 6 is adjusted to adjust the coverage of the table top 5, so that the overall height of the table top 5 can be adjusted, which is convenient for people of different heights to use.

[0034] When the desktop 5 is not in use, the locking assembly is loosened, the desktop 5 and the electric push rod 4 are folded, the electric push rod 4 is retracted, the electric push rod 4 and the desktop 5 are stored in the box body 1, and the cover plate 6 is covered on the upper end of the box body 1. After storage, the instrument panel as a whole has no protruding structure, has high aesthetics, and improves safety performance.

[0035] like Figure 1 , Figure 4 , Figure 5 As shown, the locking assembly includes a tooth plate 17, which is connected to the connecting frame 13 by means of an axis rotation. The end of the tooth plate 17 is configured to be an arc shape, so that the end is convenient for fitting and engaging with the connecting seat 12. A tooth ring 18 is fixedly connected to the middle of the side wall of the connecting seat 12, and the tooth plate 17 is meshed and engaged with the tooth ring 18. The connecting frame 13 is fixedly connected to a driving member 15 (the driving member 15 is a structure such as a servo motor that can drive parts to rotate), and the output end of the driving member 15 is fixedly connected to a driving rod 14, which is rotatably connected to the connecting frame 13, and a cam 16 is fixedly connected to the side wall of the driving rod 14, and the cam 16 is squeezed and fitted with a side of the tooth plate 17 away from the tooth ring 18.

[0036] When the driving member 15 drives the tooth plate 17 to engage with the tooth ring 18 via the driving rod 14, the tooth plate 17 is clamped to the connecting seat 12, the connecting seat 12 cannot rotate, and the angle between the table top 5 and the electric push rod 4 is fixed. When the driving member 15 drives the tooth plate 17 away from the tooth ring 18 via the driving rod 14, the connecting seat 12 can rotate in the connecting frame 13, and the table top 5 can adjust its angle.

[0037] like Figure 1-Figure 2As shown, the support assembly includes a support arm 21, which is shaped as a "U" shape. The middle part of the support arm 21 is rotatably connected to the cover plate 6. The middle length of the support arm 21 is smaller than the width of the internal space of the box body 1. Both ends of the support arm 21 are fixed with clamping rings. Two groups of clamping columns 22 are symmetrically fixed with the inner wall of the box body 1. Each group of clamping columns 22 has a plurality of clamping columns 22. The position of the clamping ring corresponds to the clamping ring of the support arm 21. The two groups of clamping rings are respectively clamped with the two groups of clamping columns 22.

[0038] When the cover plate 6 is adjusted, the support arm 21 is rotated to clamp the clamping ring onto the clamping column 22 , and the support arm 21 supports and stabilizes the cover plate 6 to prevent the cover plate 6 from rotating.

[0039] like Figure 2 , Figure 4 , Figure 8 As shown, a storage cavity 29 is formed inside the table top 5, and two groups of extension plates 8 are slidably connected in the storage cavity 29. The two groups of extension plates 8 extend in opposite directions and are arranged in an upper and lower overlapping manner.

[0040] When the two groups of extension plates 8 are stored in the storage groove, they form two layers. The two groups of extension plates 8 are pulled out from both ends of the desktop 5 to increase the area of ​​the desktop 5 .

[0041] like Figure 2 , Figure 8 , Fig. 9 As shown, the side walls of the two groups of extension plates 8 are fixedly connected to the limit blocks 30, the shape of the limit blocks 30 is set to be semi-cylindrical, and the inner wall of the storage cavity 29 is provided with two groups of slide grooves 7, the shape of the slide grooves 7 is set to be semi-cylindrical, and the limit rings are slidably connected in the slide grooves 7.

[0042] The limit block 30 is fitted with the inner wall of the slide groove 7 , and the limit block 30 effectively prevents the extension plate 8 from detaching from the desktop 5 , the semi-cylindrical slide groove 7 and the slider 11 , thereby increasing the sliding smoothness of the slider 11 in the slide groove 7 .

[0043] like Figure 1 , Figure 4 , Figure 8 , Fig. 9 As shown, the ends of the two groups of extension plates 8 are rotatably connected with folding plates 9 for increasing the area of ​​the extension plates 8. When the folding plates 9 are folded to be horizontal with the extension plates 8, the area of ​​the extension plates 8 is increased. Sliding cavities are provided on both sides of the folding plates 9. The sliding cavities are located on the side of the rotation axis of the folding plates 9 close to the desktop 5. Card slots 10 are provided on both sides of the extension plates 8. The card slots 10 correspond to the positions of the sliding cavities. A slider 11 is interactively connected in the sliding cavity. The end of the slider 11 is plugged into the card slot 10, and a flexible connecting belt 31 is fixedly connected to the end of the slider 11. The flexible connecting belt 31 runs through the card slot 10, and the end of the flexible connecting belt 31 is fixedly connected to the side wall of the extension plate 8.

[0044] The rotational connection between the folding plate 9 and the extension plate 8 is not the position of the card slot 10. When the desktop 5 is stored in the box body 1, the extension plate 8 is located in the desktop 5, and the folding plates 9 are located on both sides of the desktop 5. The folding plates 9 and the desktop 5 form a U-shape. The electric push rod 4 is located between the two groups of folding plates 9. When the folding plate 9 is rotated to be flush with the extension plate 8, the sliding cavity and the card slot 10 correspond. Pull the flexible connecting belt 31 and pull one end of the slider 11 into the card slot 10, so that the extension plate 8 and the folding plate 9 cannot rotate. Press the card block back into the sliding cavity, and the folding plate 9 can rotate. The flexible connecting belt 31 will not affect the rotation of the folding plate 9 on the side of the extension plate 8.

[0045] like Figure 1 , Figure 2 , Figure 6 , Figure 7 As shown, a fixing block 28 is fixedly connected to the side of the lower end of the desktop 5 away from the connecting seat 12, the end of the cover plate 6 is abutted with the limit block 30, the end of the desktop 5 away from the connecting seat 12 is set to a bent shape, a mounting groove 19 is opened on one side of the upper end of the box body 1, and an elastic block 20 is fixedly connected to one end of the cover plate 6, and the elastic block 20 is snap-fitted with the mounting groove 19.

[0046] The fixing block 28 limits the clamping position of the cover plate 6. Since one end of the desktop 5 is bent, the clamping position of the cover plate 6 has a certain range. The desktop 5 is clamped and supported within this range to prevent the end of the cover plate 6 from being displaced or offset, and it is also convenient for the cover plate 6 to be clamped after adjusting the angle. One end of the cover plate 6 is clamped with the upper end of the box body 1 through the elastic block 20 to prevent the cover plate 6 from opening and closing and vibrating at the upper end of the box body 1 due to bumps.

[0047] like Figure 2 As shown, a storage box 23 for placing articles is fixedly connected to one side of the cover plate 6, and articles can be placed in the storage box 23. A paper extraction port 24 is opened through the cover plate 6, and the paper extraction port 24 corresponds to the position of the storage box 23. The paper extraction port 24 is convenient for paper to pass through, so that the storage box 23 can be used as a paper extraction box. A double-sided fan 25 is fixedly connected to one side of the storage box 23, and the double-sided fan 25 exhausts air on both sides. Side air outlets 26 are opened on both sides of the box body 1, and the positions of the two groups of side air outlets 26 correspond to the double-sided fans 25. A ventilation port 27 for air circulation inside the box body 1 is opened on the back of the box body 1.

[0048] When the desktop 5 is stored, the cover plate 6 is installed on the upper end of the box body 1, and the double-sided fan 25 enters the box body 1 and faces the side air outlet 26. The double-sided fan 25 is powered by the internal circuit of the car. The double-sided fan 25 runs and blows air to the occupants of the driver's seat and the co-driver's seat through the side air outlet 26. When the desktop 5 is in use, the double-sided fan 25 blows air to the people on both sides of the desktop 5, thereby increasing the coolness and functionality of the desktop.

[0049] The working principle of the height-adjustable instrument panel provided by the present invention is as follows:

[0050] When in use, the cover plate 6 is opened, the electric push rod 4 is rotated, the electric push rod 4 is electrically driven to run, the output end of the electric push rod extends to a certain extent and stops, the table top 5 is rotated, the position and angle of the table top 5 are adjusted, the locking component is tightened, the cover plate 6 is abutted against the specified position of the lower end of the table top 5, and the cover plate 6 is fixed by the supporting component. At this time, the installation of the table top 5 is completed, and the locking component is controlled to be loose, and the angle of the electric push rod 4 is adjusted within a certain range, and the angle between the table top 5 and the electric push rod 4 is correspondingly adjusted to make the table top 5 stable, the locking component fixes the angle, and then the angle of the cover plate 6 is adjusted, the covering degree of the table top 5 can be adjusted, so that the overall height of the table top 5 can be adjusted, which is convenient for people of different heights to use. When the table top 5 is not in use, the locking component is loosened, the table top 5 and the electric push rod 4 are folded, the electric push rod 4 is retracted, the electric push rod 4 and the table top 5 are stored in the box body 1, and the cover plate 6 is set at the upper end of the box body 1. After storage, the instrument panel as a whole has no protruding structure, the aesthetics is high, and the safety performance is improved.
