For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0045] The present invention will now be described in further detail with reference to specific embodiments and accompanying drawings.

[0046] See Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, this embodiment provides a seat back electric table structure, including a table body 100, a linkage assembly 200, a drive motor 300, and a backrest support 400; the backrest support 400 is disposed on the seat back 10, the table body 100 is disposed on the backrest support 400 via the linkage assembly 200, and the drive motor 300 is disposed on the table body 100; the linkage assembly 200 includes an active linkage 210 and a driven linkage 220, one end of the active linkage 210 is pivotally connected to the backrest support, and the other end is drively connected to the drive motor 300, one end of the driven linkage 220 is pivotally connected to the backrest support, and the other end is pivotally connected to the table body 100; a groove 211 is provided on the active linkage 210.

[0047] Specifically, during use, the user triggers the drive motor 300 to operate via the control button 20. The drive motor 300 drives the table body 100 to rotate relative to the active link 210 of the linkage assembly 200. Under the constraint and linkage of the driven link 220, the table body 100 moves from a vertical state to a horizontal state, thereby completing the unfolding of the table body 100. The drive motor 300 is located inside the table body 100, and the power supply control harness of the drive motor 300 is connected to the inside of the seat back 10 through the wire receiving groove 211 on the active link 210, thereby enabling the drive motor 300 to work normally. With this setting, the table of the seat back 10 can be electrically controlled, without the need for the user to manually unfold or fold it.

[0048] A cover plate is provided in the cable tray 211 of the active link 210 to prevent the cable harness inside the cable tray 211 from being exposed.

[0049] The drive motor 300 is connected to the active connecting rod 210 via the drive shaft 310.

[0050] See Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, in an optional embodiment, the tabletop body 100 includes a tabletop frame 101, a tabletop cover, and a tabletop base; the tabletop cover is installed on the top of the tabletop frame 101, and the tabletop base is installed on the bottom of the tabletop frame 101.

[0051] The table body 100 is provided with a motor mounting base for installing the drive motor 300, and the table frame 101 is provided with a clearance channel 110 at the motor mounting location, and the drive motor 300 is located in the clearance channel 110.

[0052] Specifically, by opening an avoidance channel 110 on the table frame 101, the drive motor 300 is not restricted by the table frame 101 when it is placed between the table top cover and the table base, thereby reducing the overall thickness of the table body 100 and reducing the space occupied by the table body 100 on the seat back 10.

[0053] In addition, the control circuit board for controlling the drive motor 300 can be set inside the seat back 10, thereby minimizing the thickness and weight of the table body 100 and achieving a lightweight table body 100.

[0054] The table frame 101 is equipped with a wireless charger 600, and the table top cover has a mobile phone slot 720 at the corresponding position of the wireless charger 600, so as to wirelessly charge the mobile phone. At the same time, the wiring harness of the wireless charger 600 is connected to the seat back 10 through the wire receiving slot 211 on the active connecting rod 210.

[0055] Additionally, a cup holder 710 is provided on the tabletop body 100, and a pressure-sensitive sensor is installed at the bottom of the cup holder 710. When a user is using the tabletop body 100 and places a water cup in the cup holder 710, the user cannot retract the tabletop body 100 using the control button 20. This design allows for the detection of foreign objects on the tabletop body 100, preventing accidental operation of the tabletop and avoiding damage from falling water cups or other items.

[0056] It should be noted that a gyroscope sensor can be installed on the table frame 101. When installing the gyroscope sensor, the number of drive motors 300 is set to two. The gyroscope sensor detects the three-axis degrees of the table body 100 and corrects the running speed of the drive motors 300 in real time. For example, if the Z-axis degree on the left is higher than that on the right, the speed of the left motor is adjusted to decrease. When the degrees on the left and right sides are the same, the speed output of the left and right sides is synchronized. By continuously adjusting the PID through the data received from the gyroscope sensor, the running speed of the left and right drive motors 300 is ensured.

[0057] See Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, in an optional embodiment, the tabletop body 100 is provided with a first pivot hole for pivoting with the active link 210 and a second pivot hole for pivoting with the driven link 220; when the tabletop body 100 is unfolded, the first pivot hole is located between the second pivot hole and the backrest support 400; the driven link 220 is located above the active link 210.

[0058] Specifically, the drive motor 300 is connected to the active linkage 210 via the drive shaft 310. When the tabletop body 100 is unfolded, the drive motor 300 and the active linkage 210 are relatively stationary, and the tabletop body 100 and the drive motor 300 are relatively stationary. When the tabletop body 100 tends to rotate, the active linkage 210 and the driven linkage 220 abut against each other, preventing the tabletop body 100 from rotating, thereby ensuring the stability of the tabletop body 100.

[0059] See Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, in an optional embodiment, a wire harness protective sleeve 500 is provided on the table body 100. The wire harness protective sleeve 500 is located outside the active connecting rod 210 and corresponds to the wire receiving groove 211.

[0060] The backrest bracket 400 is equipped with a wire harness protective sleeve 500.

[0061] Specifically, by setting the wire harness protection sleeve 500, the power supply wire harness or control wire harness can be prevented from getting tangled in the wire receiving groove 211 of the active connecting rod 210, thus protecting the wire harness.

[0062] In addition, multiple wire harness fixing brackets are provided on the table frame 101 to facilitate the installation of wire harnesses by staff.

[0063] This embodiment provides a car seat, including an electric table structure for the seat back.

[0064] Specifically, the car seat provided in this embodiment has the advantages of the above-mentioned electric table structure for the seat back compared with the prior art, which will not be elaborated here.

[0065] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
