The two first limiting ribs 226 are used to limit the rotation of the driven member 222 (first gear), so that the driven member 222 (first gear) is fixedly connected to the support body 221 (for example, rigidly connected), that is, when the first transmission member 31 drives the driven member 222 (first gear) to rotate, the support body 221 rotates together with the driven member 222 (first gear).

[0131] The driven member 222 (first gear) includes a gear 2221 and four second limiting ribs 2222. The four second limiting ribs 2222 are divided into two groups and arranged on both sides of the gear 2221. The gear 2221 has a through hole (not shown). The third rotating shaft 225 is penetrated by a through hole. The second limiting ribs 2222 in one group are respectively located on both sides of the third rotating shaft 225, that is, there is a gap between the second limiting ribs 2222 in one group. When the driven member 222 (first gear) is accommodated in the through groove 2231, the first limiting ribs 226 are respectively clamped in the gap between the second limiting ribs 2222. The first limiting ribs 226 and the second limiting ribs 2222 cooperate to limit the rotation of the driven member 222 (first gear).

That is, the base plate 10, the table top body 211 and the support plate 22 are in a triangular shape. In this way, a stable triangular support can be formed between the support body 221, the base plate 10 and the table top body 21 to ensure the stability of the table top 21 when supporting.

This is beneficial to the linkage of the transmission assembly 30, the fixing member 50 and the driving member 40, so as to smoothly complete the switching of the table top 21 between the first state and the second state and between the second state and the third state.

[0136] In this embodiment, the third transmission member 33 is rotatably connected to the first transmission member 31 and the second transmission member 32. In other embodiments, the third transmission member 33 is rotatably connected to the first transmission member 31 or the second transmission member 32, and accordingly, the third transmission member 33 should avoid the first transmission member 31 or the second transmission member 32.

[0137] The first transmission member 31 is in transmission connection with the driven member 222 , and the rotation of the first transmission member 31 can drive the driven member 222 to rotate relative to the first transmission member 31 , so as to drive one end of the support body 221 that is slidably connected to the table top 21 to flip relative to the base plate 10 .

[0138] Please continue reading Figure 6 , Fig.13 and Fig.14In some embodiments of the present application, the first transmission member 31 includes a second gear shaft 311 and a second gear 312. The second gear shaft 311 passes through the substrate 10 and is rotatably connected to the substrate 10. The second gear 312 is fixed on the second gear shaft 311 and meshes with the first gear (follower 222). The extension direction of the second gear shaft 311 is perpendicular to the extension direction of the third rotating shaft 225. The second gear shaft 311 drives the second gear 312 to rotate, and the second gear 312 drives the first gear (follower 222) to rotate. Since the support body 221 is rigidly (fixedly) connected to the first gear (follower 222), the support body 221 is driven by the second gear 312 together with the first gear (follower 222) to rotate relative to the substrate 10 as a whole.

[0139] In some embodiments of the present application, the teeth of the second gear 312 are 45° helical teeth and mesh with the teeth of the first gear.

[0143] Please continue reading Figure 6 , Fig.13 and Fig.14 The second transmission member 32 includes a third gear shaft 321 and a fourth gear 322. The fourth gear 322 is fixed on the third gear shaft 321. One end of the third gear shaft 321 is fixedly connected to the driving member 40, and the other end is rotatably connected to the base plate 10 and the fixing member 50. The fourth gear 322 is located between the base plate 10 and the fixing member 50. In this embodiment, one end of the third gear shaft 321 is fixedly connected to the driving member 40.

[0144] The third transmission member 33 includes a first gear shaft 331 and a fifth gear 332. The fifth gear 332 is fixed to the first gear shaft 331. One end of the first gear shaft 331 is rotatably connected to the base plate 10, and the other end is slidably connected to the fixing member 50. The fifth gear 332 is respectively meshed with the fourth gear 322 and the third gear 313. In this way, the power generated by the driving member 40 can be transmitted to the table board assembly 20 through the transmission assembly to realize the unfolding and retracting of the table board 21.

[0145] Please refer to Fig.18 and Fig.19 In some embodiments of the present application, the end of the first gear shaft 331 away from the substrate 10 (i.e., the portion received in the arc groove 52) is a non-circular gear shaft. The end of the first gear shaft 331 away from the substrate 10 includes a first arc surface 3311, a second arc surface 3312, and a first arc connecting surface 3313 and a second arc connecting surface 3314 connecting the first arc surface 3311 and the second arc surface 3312. The center of the circle where the arc of the first arc surface 3311 is located is located on the side of the first arc surface 3311 close to the second arc surface 3312, and the center of the circle where the arc of the second arc surface 3312 is located is located on the side of the second arc surface 3312 away from the first arc surface 3311. The first arc connecting surface 3313 and the second arc connecting surface 3314 are arranged opposite to each other and protrude outward. That is, the center of the circle where the arc of the first arc-shaped connecting surface 3313 is located is located on the side of the first arc-shaped connecting surface 3313 close to the second arc-shaped connecting surface 3314, and the center of the circle where the arc of the second arc-shaped connecting surface 3314 is located is located on the side of the second arc-shaped connecting surface 3314 close to the first arc-shaped connecting surface 3313.

[0146] When the table top 21 switches from the first state to the second state, the first gear shaft 331 of the third transmission member 33 and the base plate 10 are relatively stationary, and the first gear shaft 331 does not rotate. The first gear shaft 331 slides in the first sub-groove 521, and the first arc surface 3311 and the second arc surface 3312 of the first gear shaft 331 respectively abut against the inner wall of the first sub-groove 521. When the table top 21 is in the second state, the first gear shaft 331 is located in the second sub-groove 522.

[0147] When the table top 21 switches from the second state to the third state, there are gaps between the first arc surface 3311 and the second arc surface 3312 of the first gear shaft 331 and the inner wall of the second sub-groove 522, respectively, and the first gear shaft 331 can rotate under the drive of the driving member 40. The rotation of the first gear shaft 331 can drive the first transmission member 31 to rotate, the first transmission member 31 drives the support plate 22 to flip, and the support plate 22 drives the table top 21 to flip. In this way, the table top 21 can switch between the first state and the second state and between the second state and the third state.

[0148] The present application sets the shape and size of the first gear shaft 331 and the arc groove 52 on the fixing member 50 so that the first gear shaft 331 and the base plate 10 are relatively stationary and the first gear shaft 331 does not rotate. Other means can also be used to prevent the first gear shaft 331 from rotating during the process of switching the table top 21 from the first state to the second state, such as: external fixing components, etc.

[0149] In some embodiments of the present application, the driving member 40 is a driving motor.

[0150] Please continue reading Figure 21 to Figure 25 In some embodiments of the present application, the fixing member 50 has a main shaft hole 51 and an arc groove 52, and the arc groove 52 is located on one side of the main shaft hole 51 and is arranged around the main shaft hole 51. The end of the third gear shaft 321 away from the driving member 40 is received in the main shaft hole 51 and can rotate in the main shaft hole 51. The end of the first gear shaft 331 away from the base plate 10 is received in the arc groove 52 and can slide in the arc groove 52 along the extension direction of the arc groove 52. In this way, it is conducive to realizing the connection between the fixing member 50 and the transmission assembly 30, and driving the base plate 10 and the table top assembly 20 to rotate together, so that the table top 21 switches from the first state to the second state.

[0151] The arc groove 52 includes a first sub-groove 521 and a second sub-groove 522. The first sub-groove 521 is arc-shaped, and the second sub-groove 522 is located at one end of the first sub-groove 521 and communicates with the first sub-groove 521. The size of the second sub-groove 522 is greater than the distance between the two surfaces of the first sub-groove 521 that are respectively in contact with the first arc surface 3311 and the second arc surface 3312.

[0152] In some embodiments of the present application, when the first gear shaft 331 moves in the first sub-groove 521, the first arc surface 3311 and the second arc surface 3312 of the first gear shaft 331 respectively abut against the inner wall of the first sub-groove 521, and the size of the first gear shaft 331 matches the size of the first sub-groove 521 and is smaller than the size of the second sub-groove 522. When the first gear shaft 331 moves in the second sub-groove 522 and does not rotate, there is a gap between the first arc surface 3311 and the second arc surface 3312 of the first gear shaft 331 and the inner wall of the first sub-groove 521. When the first gear shaft 331 moves in the second sub-groove 522 and rotates, the first arc connecting surface 3313 and the second arc connecting surface 3314 of the first gear shaft 331 are in contact with each other or have a gap. In this way, the first gear shaft 331 can slide in the first sub-groove 521 and the second sub-groove 522 respectively and can rotate in the second sub-groove 522, and the first sub-groove 521 restricts the first gear shaft 331 from rotating in the first sub-groove 521. In this way, the table board 21 can be switched between the first state and the second state or between the second state and the third state.

[0153] In some embodiments of the present application, the fixing member 50 includes a fixing member body 501 and a limiting portion 502. The main shaft hole 51 and the arc groove 52 are arranged on the fixing member body 501, and the limiting portion 502 is fixedly connected to one end of the fixing member body 501 having the main shaft hole 51 and the arc groove 52. Compared with the first sub-groove 521, the limiting portion 502 is closer to the second sub-groove 522. Among them, the limiting portion 502 is also located on one side of the base plate 10 away from the end of the table top 21 to limit the rotation angle of the base plate 10.

[0154] Please continue reading Figures 1 to 5 In some embodiments of the present application, when the table top 21 switches from the first state to the second state, the first gear shaft 331 slides in the first sub-groove 521; when the table top 21 is in the second state, the first gear shaft 331 is located in the second sub-groove 522; when the table top 21 switches from the second state to the third state, the first gear shaft 331 rotates; when the table top 21 is in the third state, the first gear shaft 331 is located in the second sub-groove 522, and the extension direction of the first arc surface 3311 of the first gear shaft 331 intersects with the extension direction of the first arc surface 3311 of the first gear shaft 331 when it is in the second state.

The avoidance groove 621 can avoid the end of the substrate 10 when the table top is unfolded or retracted, so as to smoothly realize the unfolding or retraction of the table top 21.

[0157] When the table top 21 is in the second state and the third state, the first end 11 of the base plate 10 is received in the escape space 63 , and the end surface of the first end 11 of the base plate 10 away from the second end 12 faces the escape groove 621 .

The fifth gear 332 of the third transmission member 33 is respectively meshed with the fourth gear 322 and the third gear 313. The second fixing portion 62 of the fixing block 60 is fixed to the fixing member 50.

[0166] When the electric table top 100 is unfolded, the coordination of the various components is as follows:

[0167] Please continue reading Figure 1 and Fig. 22In the initial state (first state), one end of the first gear shaft 331 is located at the end of the first sub-groove 521 of the arc groove 52 that is farthest from the second sub-groove 522, the support body 221 is completely received in the second groove 122 of the base plate 10 and the receiving groove 213 of the table top 21, and the first rotating shaft 223 on the support body 221 is located at the end of the slide groove 214 close to the base plate 10. The base plate 10, the support body 221 and the table top body 211 all extend along the first direction, and the fixing member body 501 of the fixing member 50 extends along the second direction.

[0168] Please continue reading Figure 2 , Fig.23 and Fig.24 , the driving member 40 is started, the driving member 40 drives the third gear shaft 321 to rotate, the fourth gear 322 rotates with the third gear shaft 321 and drives the fifth gear 332 to rotate, the fifth gear 332 drives the first gear shaft 331 and the base plate 10 (the first gear shaft does not rotate) to rotate, the first gear shaft 331 slides in the first sub-groove 521, the base plate 10 rotates around the third gear shaft 321 until the base plate 10 is limited by the limiting portion 502 of the fixing member 50 and the second sub-groove 522, and the table top 21 switches from the first state to the second state. The base plate 10, the supporting body 221, the table top body 211 and the fixing body 501 of the fixing member 50 all extend along the second direction. In this process, the base plate 10 rotates 90°, and one end of the first gear shaft 331 is located at the end of the second sub-groove 522 of the arc groove 52 that is farthest from the first sub-groove 521.

Since the driven member 222 is rigidly connected to the supporting body 221, the second gear 312 drives one end of the supporting body 221 to rotate, thereby driving the other end of the supporting body 221 to slide in the slide groove 214 of the table board 21 to the top of the slide groove 214 until it is limited by the end of the slide groove 214, thereby driving the table board body 211 to rotate and flip 90° relative to the base plate 10, and the table board body 211 is unfolded. During this process, one end of the first gear shaft 331 located in the second sub-groove 522 of the arc groove 52 rotates a certain angle, which needs to be less than 180°. In this solution, the rotation angle is 130°. The other end of the support body 221 rotates while sliding in the slide groove 214 of the table top 21.
