Description

Technical Field

[0001] This utility model relates to the field of adjustment structure technology, specifically an automatic horizontal adjustment structure for an electric tabletop for car seats. Background Technology

[0002] A car seat tray is a structure installed on the back of a car seat, with a tray that can be flipped to a horizontal position for placing items. A car seat tray typically includes a mounting plate that is installed on the car seat, a tray for flipping to place items, and a connector that connects the mounting plate and the tray.

[0003] Existing car seat tables typically involve manually or automatically flipping them down. A connecting piece rotates to a certain angle to open the table. For example, CN 220349549 U discloses a car seat table adjustment mechanism, including a mounting plate mounted on the car seat. The mounting plate has a storage cavity, and a table is located on one side of the mounting plate with the storage cavity. The table includes an upper table and a lower table, with a connecting piece between the lower table and the mounting plate. One end of the connecting piece connects to the mounting plate, and the other end passes through an adjustment hole and connects to the mounting plate via a pivot. This car seat table adjustment mechanism uses a connecting piece to connect the mounting plate and the table. Flipping the table down to a fixed angle generally results in a horizontal table. However, when the car is parked on a slope, the car body is not horizontal, and the table will also be non-horizontal when flipped down, making it inconvenient to use. Therefore, the use of this car seat table is limited, affecting the user experience. Utility Model Content

[0004] This utility model discloses an automatic leveling structure for electric tables in automobile seats, in order to solve the technical problem that the table will also be non-horizontal when the car body is in a non-horizontal state after being flipped down.

[0005] To solve the above-mentioned technical problems, the present invention proposes the following optimized technical solution:

[0006] An automatic leveling structure for an electric tabletop for a car seat includes a gyroscope, a rotary drive, and a connecting assembly. Both the rotary drive and the gyroscope are mounted on the tabletop. The gyroscope has a control circuit board and a sensor connected to the control circuit board. The control circuit board is electrically connected to the rotary drive. The output shaft of the rotary drive is connected to a drive shaft. The drive shaft passes through one side of the tabletop and is connected to one end of the connecting assembly. The other end of the connecting assembly is rotatably connected to a mounting plate of the car seat. The rotary drive drives the tabletop to rotate relative to the mounting plate via the drive shaft.

[0007] Furthermore, the bottom of the gyroscope is arranged parallel to the tabletop.

[0008] Furthermore, the rotary drive component is provided with two output shafts, and the number of drive shafts is two. The two output shafts are respectively connected to the two drive shafts. The connecting component includes a left connector and a right connector. The left connector and the right connector are respectively disposed on the left and right sides of the table and are respectively connected to the two drive shafts.

[0009] Furthermore, the left connector includes a first connecting strip and a first rotating shaft. One end of the first connecting strip is provided with a first rotating hole through which the drive shaft passes, and the other end is rotatably connected to the mounting plate via the first rotating shaft.

[0010] Furthermore, the left connector also includes a second connecting strip and a second rotating shaft. One end of the second connecting strip is provided with a first rotating groove for the connecting shaft of the tabletop to be inserted, and the other end is rotatably connected to the mounting plate through a second shaft pin.

[0011] Furthermore, the right connector includes a third connecting strip and a third rotating shaft. One end of the third connecting strip is provided with a second rotating hole through which the drive shaft passes, and the other end is rotatably connected to the mounting plate via the third rotating shaft.

[0012] Furthermore, the right connector also includes a fourth connecting strip and a fourth rotating shaft. One end of the fourth connecting strip is provided with a second rotating groove for the connecting shaft of the tabletop to be inserted, and the other end is rotatably connected to the mounting plate through a fourth shaft pin.

[0013] The present invention has the following advantages over the prior art:

[0014] The automatic leveling structure provided by this utility model includes a gyroscope, a rotation drive, and a connecting component. The rotation drive drives the table to flip down. After the table flips down, the sensor in the gyroscope can detect whether the table is in a horizontal state. When the table is not in a horizontal state, the control circuit board in the gyroscope sends a control signal to the rotation drive. The rotation drive flips the table to a horizontal state according to the control signal. The simple structure easily solves the technical problem that the table cannot be placed horizontally when the car body is on a slope, greatly improving the user experience.

Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0022] See Figures 1-5 An automatic leveling structure for an electric tabletop for a car seat includes a gyroscope 1, a rotation drive 2, and a connecting assembly. Both the rotation drive 2 and the gyroscope 1 are mounted on a tabletop 15. The gyroscope 1 has a control circuit board 3 and a sensor connected to the control circuit board 3. The control circuit board 3 is electrically connected to the rotation drive 2. The output shaft of the rotation drive 2 is connected to a drive shaft 4. The drive shaft 4 passes through one side of the tabletop 15 and is connected to one end of the connecting assembly. The other end of the connecting assembly is rotatably connected to a mounting plate 9 of the car seat. The rotation drive 2 drives the tabletop 15 to rotate relative to the mounting plate 9 via the drive shaft 4.

[0023] In the above technical solution, the rotary drive 2 is activated, and the rotary drive 2 rotates to drive the drive shaft 4 to rotate. Since the drive shaft 4 passes through one end of the tabletop 15, the tabletop 15 is driven by the drive shaft 4 to flip downwards. During the flipping process, the sensor of the control circuit board 3 senses whether the tabletop 15 is in a horizontal state. When the tabletop 15 is in a horizontal state, the control circuit board 3 sends a control signal to control the rotary drive 2 to stop working, thereby keeping the tabletop 15 in a horizontal state. If the tabletop 15 is still not in a horizontal state after flipping to a normal angle, the control circuit board 3 sends a control signal to control the rotary drive 2 to continue working until the tabletop 15 is in a horizontal state, at which point the rotary drive 2 stops working, thereby ensuring that the tabletop 15 is in a horizontal state.

[0024] In this embodiment, the bottom of the gyroscope 1 is arranged parallel to the tabletop 15, and the gyroscope 1 is kept horizontal so that the tabletop 15 follows the gyroscope 1 to keep horizontal.

[0025] In this embodiment, the rotary drive 2 is provided with two output shafts, and the number of drive shafts 4 is two. The two output shafts are respectively connected to the two drive shafts 4. The connecting assembly includes a left connector 5 and a right connector 6. The left connector 5 and the right connector 6 are respectively disposed on the left and right sides of the table 15 and are respectively connected to the two drive shafts 4. That is, the rotary drive 2 is connected to the left connector 5 and the right connector 6 through the two drive shafts 4, which is more reasonable in terms of structure.

[0026] Additionally, the rotary drive 2 is a motor with dual output shafts.

[0027] In this embodiment, the left connecting member 5 includes a first connecting strip 7 and a first rotating shaft 8. One end of the first connecting strip 7 is provided with a first rotating hole 10 for the drive shaft 4 to pass through, and the other end is rotatably connected to the mounting plate 9 via the first rotating shaft 8. One end of the drive shaft 4 is connected to the output shaft of the rotary drive member 2, and the other end passes through one end of the tabletop 15 and the first through hole. When the output shaft of the rotary drive member 2 rotates, since the drive shaft 4 is fixedly connected to one end of the left connecting member 5, the output shaft of the rotary drive member 2 cannot drive the left connecting member 5 to rotate, thereby causing the rotary drive member 2 to rotate, that is, the rotary drive member 2 drives the tabletop 15 to rotate, causing the tabletop 15 to flip down.

[0028] In this embodiment, the left connecting member 5 further includes a second connecting strip 11 and a second rotating shaft 12. One end of the second connecting strip 11 is provided with a first rotating groove for the connecting shaft of the tabletop 15 to be inserted, and the other end is rotatably connected to the mounting plate 9 via a second shaft pin. The connecting shaft of the tabletop 15 is inserted into the first rotating groove and can rotate within the first rotating groove. When the tabletop 15 is flipped down, the connecting shaft rotates within the first rotating groove. Due to the traction force of the second connecting strip 11 on the tabletop 15, the tabletop 15 can rise to a certain height and will not rotate completely around the drive shaft 4 as the pivot. This structure makes the tabletop 15 more stably supported.

[0029] In this embodiment, the right connector 6 includes a third connecting strip and a third rotating shaft. One end of the third connecting strip is provided with a second rotating hole through which the drive shaft 4 passes, and the other end is rotatably connected to the mounting plate 9 via the third rotating shaft.

[0030] In this embodiment, the right connector 6 further includes a fourth connecting strip and a fourth rotating shaft. One end of the fourth connecting strip is provided with a second rotating groove for the connecting shaft of the table 15 to be inserted, and the other end is rotatably connected to the mounting plate 9 through a fourth shaft pin.

[0031] The above description is merely a specific embodiment of the present invention, enabling those skilled in the art to understand or implement the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features claimed herein.
