[0055] Specifically, if Figure 1The schematic diagram of the structure of the electric table top device provided in the embodiment of the present application is shown, and the electric table top device includes a box body 1, a driving member 2, a transmission mechanism 3, a first rotating arm 4 and a table top assembly 51.

Among them, the first direction is Figure 1 The X direction, the second direction is Figure 1 In the Z direction, the X direction is perpendicular to the Z direction. Then, driven by the transmission mechanism 3, the table top assembly 51 rotates in the horizontal and vertical directions relative to the box body 1, switching between the storage state and the unfolded state.

[0056] Specifically, if Figure 1 The electric table device is in the storage state, such as Figure 3 The electric table device is in the unfolded state. Figure 1 to Figure 2 As shown, driven by the transmission mechanism 3, the first rotating arm 4 rotates around the X direction relative to the box body 1 to a vertical position; Figures 2 to 3 As shown, driven by the transmission mechanism 3, the table assembly 51 rotates around the Z direction relative to the first rotating arm 4 to a horizontal position, that is, the unfolded state of the electric table device. Figure 3 to Figure 1 The diagram illustrates the process of the electric table top device changing from an unfolded state to a folded state.

[0057] In the embodiment of the present application, the driving member 2 drives the transmission mechanism 3 to operate, thereby driving the table top assembly 51 to rotate in two directions relative to the box body 1. There is no need to provide a guide portion on the box body 1. The device structure is compact and simple, and the space occupied is small.

[0059] Specifically, if Figures 4 to 6 As shown, the transmission mechanism 3 includes a first transmission assembly 31 and a second transmission assembly 32. The first transmission assembly 31 is connected to the power output shaft 21 of the driving member 2, one end of the first transmission assembly 31 is rotatably connected to the box body 1, and the other end of the first transmission assembly 31 is connected to the first rotating arm 4. The first transmission assembly is rotatably connected to one side of the second transmission assembly 32, and the other side of the second transmission assembly 32 is movably connected to the table board assembly 51. When the driving member 2 is powered on, the first transmission assembly 31 is driven to rotate, and the first rotating arm 4 is driven to rotate relative to the box body 1 around the first direction X through the first transmission assembly 31, and the second transmission assembly 32 is driven to rotate, so as to realize the rotation of the table board assembly 51 relative to the box body 1 in two directions. The first transmission assembly 31 adopts a transmission mechanism in combination with a rotating shaft and a gear, and the second transmission assembly 32 includes but is not limited to a gear transmission mechanism or a gear transmission mechanism and a connecting rod transmission mechanism.

[0061] Specifically, if Figures 6 to 8As shown, the first transmission assembly 31 includes a first rotating shaft 311, a first transmission wheel 312 and a second transmission wheel 313. One end of the first rotating shaft 311 is connected to the driving member 2, and the other end of the first rotating shaft 311 is connected to the matching hole 41 of the first rotating arm 4. The first transmission wheel 312 is connected to the first rotating shaft 311 near the other end. The second transmission wheel 313 is engaged with the outer peripheral side of the first transmission wheel 312 and can rotate under the drive of the first transmission wheel 312. The first rotating arm is provided with a mounting shaft 42, and each second transmission wheel 313 is mounted on the mounting shaft 42. The mounting shaft 42 provides a rigid support point for the second transmission wheel 313, and enables the second transmission wheel 313 to rotate around the outer periphery of the first transmission wheel 312 while driving the first rotating arm 4 to rotate. Optionally, refer to Figure 4 and Figure 7 The second transmission assembly 32 includes a ring gear 321 and a transmission connecting member 322; there are at least two second transmission wheels 313, at least two of which are arranged around the outer peripheral side of the first transmission wheel 312, the ring gear 321 is sleeved on the outer peripheral side of at least two second transmission wheels 313, and the outer peripheral side of the second transmission wheel 313 is meshed with the inner peripheral side of the ring gear 321, and the second transmission wheel 313 is rotatably mounted on the mounting shaft 42; the transmission connecting member 322 is connected to the outer side of the ring gear 321, and the table board assembly 51 is connected to the transmission connecting member 322.

[0062] Specifically, the second transmission assembly 32 includes a gear ring 321 and a transmission connector 322. There are at least two second transmission wheels 313. In this embodiment, three second transmission wheels 313 are arranged, and the three second transmission wheels 313 are circumferentially arranged around the outer peripheral side of the first transmission wheel 312. The gear ring 321 is sleeved on the outer peripheral side of the second transmission wheel 313, and the gear ring 321 and the second transmission wheel 313 are meshed. The second transmission wheel 313 is rotatably mounted on the mounting shaft 42, that is, the second transmission wheel 313 can drive the first rotating arm 4 to rotate, and the second transmission wheel 313 can rotate relative to the mounting shaft 42. The outer peripheral side of the second transmission wheel 313 is meshed with the outer peripheral side of the first transmission wheel 312, so the gear ring 321, the second transmission wheel 313 and the first transmission wheel 312 constitute a planetary gear mechanism. Among them, the first transmission wheel 312 is also called the sun wheel, corresponding to the power input end of the planetary gear mechanism, the ring gear 321 corresponds to the power input end of the planetary gear mechanism, the second transmission wheel 313 is also called the planetary wheel, one end of the transmission connection member 322 is rotatably connected to the outer side of the ring gear 321, and the other end is connected to the table top assembly 51. The transmission connection member 322 can adopt a staggered gear transmission mechanism or a connecting rod transmission mechanism to convert the rotation of the ring gear 321 around the first direction X into the rotation of the table top assembly 51 around the second direction Z.

[0063] The ring gear 321, the second transmission wheel 313 and the first transmission wheel 312 of this embodiment constitute a planetary gear mechanism. The second transmission wheel 313 and the first transmission wheel 312 are located inside the ring gear 321. The second transmission wheel 313 meshes with the inner side of the ring gear 321, making full use of the internal space of the ring gear 321, making the structure compact and reducing the size of the device. Compared with other belt drive or chain drive mechanisms, it has strong stability, small size, light weight, compact structure, large transmission power and high load-bearing capacity.

[0064] Optionally, refer to Figure 4 and Figure 5 The transmission connecting member 322 includes a transmission wheel structure 3221, a second rotating arm 3226, a second rotating shaft 71 and a third transmission wheel 3222; the second rotating shaft 71 is rotationally connected to the first rotating arm 4, and the third transmission wheel 3222 is arranged on the second rotating shaft 71; a slide groove 511 is provided in the table top assembly 51, one end of the second rotating arm 3226 is fixedly connected to the second rotating shaft 71, and the other end of the second rotating arm 3226 is slidingly connected to the slide groove 511; the transmission wheel structure 3221 is at least partially penetrated by the first rotating arm 4, and the transmission wheel structure 3221 can rotate relative to the first rotating arm 4, the transmission wheel structure 3221 is rotationally connected to the outer side of the ring gear 321, the other end of the transmission wheel structure 3221 is rotationally connected to the third transmission wheel 3222, and the third transmission wheel 3222 is rotationally connected to the transmission wheel structure 3221.

[0065] Specifically, if Figure 4 , Figure 5 As shown, the transmission connecting member 322 includes a transmission wheel structure 3221, a second rotating arm 3226, a second rotating shaft 71 and a third transmission wheel 3222. The first rotating arm 4 is provided with a rotating shaft hole for connecting the transmission wheel structure 3221. The transmission wheel structure 3221 is at least partially inserted into the rotating shaft hole of the first rotating arm 4. The first rotating arm 4 provides a supporting structure for the transmission wheel structure 3221. The third transmission wheel 3222 is fixedly connected to one end of the table board assembly 51 close to the first rotating arm 4 through the second rotating shaft 71. One end of the transmission wheel structure 3221 meshes with the outer side of the gear ring 321, and the other end meshes with the third transmission wheel 3222. Therefore, when the gear ring 321 rotates, the transmission wheel structure 3221 drives the third transmission wheel 3222 to rotate under the drive of the gear ring 321. The transmission wheel structure 3221 and the third transmission wheel 3222 are connected by staggered gears, and a helical gear or bevel gear connection structure can be used to convert the rotation of the ring gear 321 around the first direction X into the rotation of the third transmission wheel 3222 around the second direction Z, thereby driving the table top assembly 51 to rotate around the second direction Z relative to the first rotating arm 4.

[0066] Specifically, if Figure 7As shown, the table board assembly 51 has a main body of a table board, on which articles in the vehicle can be placed. A slide groove 511 is provided in the table board assembly 51. One end of the second rotating arm 3226 is rotatably connected to the first rotating arm 4, and the other end is slidably connected on the slide groove 511. The third transmission wheel 3222 is fixedly connected to one end of the second rotating arm 3226 close to the first rotating arm 4. The third transmission wheel 3222 is fixedly connected to one end of the second rotating arm 3226 close to the first rotating arm 4 through the second rotating shaft 71. Therefore, the second rotating arm 3226 rotates relative to the first rotating arm 4 around the second direction Z under the drive of the transmission wheel structure 3221 and the third transmission wheel 3222. A fourth rotating shaft 72 is provided between the table board assembly 51 and the first rotating arm 4, and the fourth rotating shaft 72 extends along the second direction Z. The rotation of the second rotating arm 3226 simultaneously drives the table board assembly 51 to rotate relative to the first rotating arm 4 around the second direction Z, and the other end of the second rotating arm 3226 slides on the slide groove 511. Specifically, a slide rail can be set on the side of the slide groove 511, and a sliding member can be set on the side of the second rotating arm 3226. The sliding member slides in the slide rail to improve the stability of sliding. Since the slide groove 511 has a certain travel range, when the other end of the second rotating arm 3226 slides to the bottom of the slide groove 511 away from the first rotating arm 4, the second rotating arm 3226 cannot continue to slide, so the rotation of the second rotating arm 3226 and the table board assembly 51 is stopped. With the help of the slide groove 511, the rotation range of the second rotating arm 3226 and the table board assembly 51 can be limited, and the movement range of the device in the unfolding and storage stages can be effectively controlled.

[0067] Optionally, refer to Figure 4 , Figure 5 and Fig.10 The transmission wheel structure 3221 includes a third rotating shaft 32211, a fourth transmission wheel 32212 and a fifth transmission wheel 32213; the third rotating shaft 32211 is rotationally connected to the first rotating arm 4, the fourth transmission wheel 32212 is connected to one end of the third rotating shaft 32211, and the fifth transmission wheel 32213 is connected to the other end of the third rotating shaft 32211; the fourth transmission wheel 32212 is meshed with the outer side of the ring gear 321, and the fifth transmission wheel 32213 is meshed with the third transmission wheel 3222.

[0068] Specifically, if Figure 4 , Figure 5 and Fig.10As shown, the transmission wheel structure 3221 includes a third rotating shaft 32211, a fourth transmission wheel 32212 and a fifth transmission wheel 32213. Among them, the third rotating shaft 32211 and the fifth transmission wheel 32213 constitute a staggered gear shaft structure, the fourth transmission wheel 32212 is connected to one end of the third rotating shaft 32211, and the fifth transmission wheel 32213 is connected to the other end of the third rotating shaft 32211. Since the ring gear 321 is usually a straight tooth, the fourth transmission wheel 32212 meshing with the ring gear 321 is also a straight tooth. The fifth transmission wheel 32213 and the third transmission wheel 3222 are set as helical teeth or bevel teeth. Therefore, by setting the staggered gear shaft structure, this embodiment realizes the conversion of the rotation of the fourth transmission wheel 32212 around the first direction X into the rotation of the third transmission wheel 3222 around the second direction Z, thereby driving the table board assembly 51 to rotate around the second direction Z.

[0069] Optionally, refer to Figures 1 to 4 The electric table top device further includes a first limit member 14 and a second limit member 15 , and the first limit member 14 and the second limit member 15 are spaced apart from each other in the box body 1 , and are used to limit the rotation position of the first rotating arm 4 .

[0070] Specifically, if Figure 1 and Figure 4 As shown, the box body 1 is provided with a first limiter 14 and a second limiter 15 at intervals. The first limiter 14 is provided on the side panel 11, and the second limiter 15 is provided on the box body 13. Both the first limiter 14 and the second limiter 15 are located on the rotation path of the first rotating arm 4, and are used to limit the rotation position of the first rotating arm 4. The setting positions of the first limiter 14 and the second limiter 15 can be determined according to the use requirements. The larger the distance between the first limiter 14 and the second limiter 15, the larger the range of rotation of the first rotating arm 4. The coordinated setting of the first limiter 14, the second limiter 15 and the slide groove 511 can simultaneously limit the rotation range of the first rotating arm 4 relative to the box body 1 and the second rotating arm 3226 relative to the first rotating arm 4, so as to meet the rotation requirements of the table board at different stages of storage and unfolding.

[0071] Optionally, refer to Figures 7 to 9 The electric table top device also includes a first elastic member 61; the first elastic member 61 is arranged between the first rotating arm 4 and the second rotating arm 3226, one end of the first elastic member 61 is connected to the first rotating arm 4, and the other end is connected to the second rotating arm 3226.

[0072] Specifically, if Figures 7 to 9As shown, a first elastic member 61 is provided between the first rotating arm 4 and the second rotating arm 3226, and the first elastic member 61 includes but is not limited to a torsion spring, a gas spring or a rubber spring. The first elastic member 61 of this embodiment adopts a torsion spring, and its main body is in the shape of a spiral column, with torsion arms at both ends, one end of the torsion arm is fixed to the first rotating arm 4, and the other end of the torsion arm is fixed to the second rotating arm 3226. When in a free state, relying on the fastening effect of the first elastic member 61 itself, a fixing force is generated between the first rotating arm 4 and the second rotating arm 3226, and relative rotation is not easy to occur; when in a deformed state, the first elastic member 61 itself has a torsion force, so that relative rotation is easier to occur between the first rotating arm 4 and the second rotating arm 3226. Therefore, by setting different states of the first elastic member 61, the movement or fixation between the first rotating arm 4 and the second rotating arm 3226 is limited. When the first rotating arm 4 and the second rotating arm 3226 rotate relative to each other, the first elastic member 61 in the deformed state will drive the relative rotation between the first rotating arm 4 and the second rotating arm 3226 during the process of restoring the deformation. When the first elastic member 61 returns to the free state, the relative rotation between the first rotating arm 4 and the second rotating arm 3226 is restricted. In addition, the first elastic member 61 is sleeved on the second rotating shaft 71 extending along the second direction Z between the first rotating arm 4 and the second rotating arm 3226 to enhance the position stability of the first elastic member 61 and prevent it from deviating and shaking.

[0073] Optionally, refer to Figure 7 and Figure 8 The electric table top device also includes a second elastic member 62; the second elastic member 62 is arranged between the box body 1 and the first rotating arm 4, one end of the second elastic member 62 is connected to the box body 1, and the other end is connected to the first rotating arm 4.

[0074] Specifically, if Figure 7 and Figure 8 As shown, a second elastic member 62 is provided between the first rotating arm 4 and the side plate 11. The second elastic member 62 of this embodiment also adopts a torsion spring. By setting different states of the second elastic member 62, the movement or fixation between the first rotating arm 4 and the side plate 11 is limited. In addition, the second elastic member 62 is sleeved on the first rotating shaft 311 between the first rotating arm 4 and the side plate 11 to enhance the position stability of the second elastic member 62.

[0075] Optionally, refer to Figure 7 and Figure 8 When the table top assembly 51 is in the stored state, the first elastic member 61 is in a free state and the second elastic member 62 is in a deformed state; when the table top assembly 51 is in the unfolded state, the first elastic member 61 is in a deformed state and the second elastic member 62 is in a free state.

[0076] Specifically, if Figure 7 and Figure 8 As shown, the table board assembly 51 is in the storage state, the first elastic member 61 is in a free state, and the second elastic member 62 is in a deformed state. At this time, it is not easy for the first rotating arm 4 and the second rotating arm 3226 to rotate relative to each other. The first rotating arm 4 and the side plate 11 first rotate relative to each other around the first direction X until the first rotating arm 4 rotates to a vertical position and is restricted by the first limit member 14, and the second elastic member 62 recovers its deformation. Then, the second rotating arm 3226 rotates relative to the first rotating arm 4 around the second direction Z, and the second rotating arm 3226 also drives the table board assembly 51 to rotate relative to the first rotating arm 4. At the same time, the first elastic member 61 is compressed and deformed until the end of the second rotating arm 3226 slides to the bottom of the slide groove 511, and the table board assembly 51 rotates to a horizontal position and stops rotating. At this time, the table board assembly 51 is in an unfolded state, and the first elastic member 61 is in a compressed and deformed state, and the second elastic member 62 is in a free state. Therefore, the first elastic member 61 and the second elastic member 62 are set in different states in the unfolding and storage stages, and cooperate with the first limit member 14 and the second limit member 15 to realize the separate rotation of the first rotating arm 4 and the second rotating arm 3226, thereby effectively reducing the space occupied by the table top in the unfolding and storage stages.

[0077] In some embodiments, the movement process of the electric table device during the unfolding and folding stages is as follows:

[0078] Expand the first stage, such as Figure 1 to Figure 2 As shown, the first rotating arm 4 rotates. At the beginning of the unfolding stage, the first elastic member 61 is in a free state and the second elastic member 62 is in a deformed state. At this time, it is not easy for the first rotating arm 4 and the second rotating arm 3226 to rotate relative to each other. The driving member 2 drives the first rotating shaft 311, the first transmission wheel 312 and the second transmission wheel 313 to rotate, driving the first rotating arm 4 to rotate around the first direction X. At the same time, due to the action of the first elastic member 61, the second rotating arm 3226 does not rotate relative to the first rotating arm 4, the ring gear 321 and the transmission connecting member 322 do not rotate relative to each other, and the second rotating arm 3226 and the table board assembly 51 do not rotate relative to the first rotating arm 4. In this process, the second elastic member 62 gradually recovers to a free state until the first rotating arm 4 rotates to a vertical position. At this time, the position of the first rotating arm 4 is restricted by the first limit member 14 and cannot continue to move, and the second elastic member 62 is in a free state.

[0079] Expand the second stage, such as Figures 2 to 3As shown, the second rotating arm 3226 and the table board assembly 51 rotate. The driving member 2 continues to drive the first rotating shaft 311, the first transmission wheel 312 and the second transmission wheel 313 to rotate. Since the first rotating arm 4 is limited and cannot move at this time, the ring gear 321 rotates, and the meshing point between the ring gear 321 and the second transmission wheel 313 changes. The rotation of the ring gear 321 drives the fourth transmission wheel 32212, the fifth transmission wheel 32213 and the third transmission wheel 3222 to rotate, so that the second rotating arm 3226 and the table board assembly 51 rotate relative to the first rotating arm 4 around the second direction Z. At this time, the first rotating shaft 311 and the first rotating arm 4 rotate relative to each other. At the same time, one end of the second rotating arm 3226 slides in the slide groove 511, and the first elastic member 61 is gradually compressed and deformed. Until the end of the first rotating arm 4 slides to the bottom of the slide groove 511, the table board assembly 51 rotates to a horizontal position and stops rotating. At this time, the table board assembly 51 is in an unfolded state.

[0080] The first stage of storage, such as Figure 3 to Figure 2 As shown, the first rotating arm 4 and the table board assembly 51 rotate. Compared with the unfolding stage, the power output shaft 21 of the driving member 2 is reversed. At the beginning of the storage stage, the first elastic member 61 is in a deformed state and the second elastic member 62 is in a free state. At this time, the first rotating arm 4 does not move relative to each other. Then the first rotating shaft 311 and the first rotating arm 4 rotate relative to each other. Under the drive of the power output shaft 21, the first transmission wheel 312 drives the second transmission wheel 313 and the gear ring 321 to rotate, and the meshing point between the gear ring 321 and the second transmission wheel 313 changes, thereby driving the fourth transmission wheel 32212, the fifth transmission wheel 32213 and the third transmission wheel 3222 to rotate, so that the second rotating arm 3226 and the table board assembly 51 rotate relative to the first rotating arm 4 around the second direction Z, and the first elastic member 61 gradually recovers to the free state. At the same time, the second rotating arm 3226 slides in the slide groove 511 until it cannot slide further at the limit position. At this time, the table board assembly 51 rotates to a vertical position.

[0081] The second stage of storage, such as Figure 2 to Figure 1 As shown, the first rotating arm 4 rotates. The driving member 2 continues to drive the first rotating shaft 311, the first transmission wheel 312 and the second transmission wheel 313 to rotate. Due to the action of the first elastic member 61, the second rotating arm 3226 does not rotate relative to the first rotating arm 4. The rotation of the first rotating shaft 311 drives the first rotating arm 4 to rotate around the first direction X. The gear ring 321 and the transmission connecting member 322 do not rotate. The second rotating arm 3226 and the table board assembly 51 do not rotate relative to the first rotating arm 4. Until the first rotating arm 4 rotates to a horizontal position and is limited by the second limit member 15, the table board assembly 51 is in a storage state.

[0082] Optionally, refer to Fig.11The transmission connecting member 322 includes a first connecting rod 3223, a connecting member 3224 and a second connecting rod 3225; one end of the first connecting rod 3223 is rotationally connected to the outer side of the ring gear 321, the other end of the first connecting rod 3223 is rotationally connected to the connecting member 3224 around the first direction, the second connecting rod 3225 is rotationally connected to the connecting member 3224 around the second direction, and the second connecting rod 3225 is rotationally connected to the table top assembly 51.

[0083] Specifically, if Fig.11 As shown, in this embodiment, the transmission connecting member 322 adopts a connecting rod transmission structure, and the transmission connecting member 322 is connected between the ring gear 321 and the table board assembly 51, so that the ring gear 321 directly drives the table board assembly 51 to rotate. A fifth rotating shaft 32241 is provided at one end of the connecting member 3224, and a sixth rotating shaft 32242 is provided at the other end. The fifth rotating shaft 32241 extends along the first direction X, and the sixth rotating shaft 32242 extends along the second direction Z. One end of the first connecting rod 3223 is rotationally connected to the outer side of the ring gear 321, and the other end is rotationally connected to the fifth rotating shaft 32241. One end of the second connecting rod 3225 is rotationally connected to the table board assembly 51 along the second direction Z, and the other end is rotationally connected to the sixth rotating shaft 32242. Therefore, the transmission connecting member 322 converts the rotation of the input end around the first direction X into the rotation of the output end around the second direction Z.

[0084] In addition, in order to realize the separate movement of the first rotating arm 4 and the table top assembly 51, the electric table top device of this structure is also provided with a second rotating arm 3226, and a first elastic member 61 is provided between the first rotating arm 4 and the second rotating arm 3226, and a second elastic member 62 is provided between the first rotating arm 4 and the side panel 11.

[0086] Specifically, the outer diameter of the first rotating shaft 311 is slightly smaller than the inner diameter of the matching hole 41, so that the first rotating shaft 311 and the matching hole 41 form a shaft-hole matching relationship. When the first rotating arm 4 is not limited and fixed, the first rotating shaft 311 rotates synchronously with the first rotating arm 4, or, when the first rotating arm 4 is limited and fixed, the first rotating shaft 311 continues to rotate and relatively rotates with the first rotating arm 4. Specifically, when the first rotating shaft 311 is driven by the driving member 2 to rotate, it can drive the first rotating arm 4 to rotate relative to the box body 1 around the first direction X; when the first rotating arm 4 is limited and stops rotating, the first rotating shaft 311 continues to rotate and relatively rotates with the first rotating arm 4. A first bushing 81 is arranged between the first rotating shaft 311 and the matching hole 41, and the first rotating shaft 311 and the first bushing 81 can rotate relatively, and the first bushing 81 is fixed in the matching hole 41. The first bushing 81 provides a supporting function on the one hand, and reduces the wear, vibration and noise of the rotating shaft on the other hand, thereby extending the service life of the rotating shaft.

[0087] Optionally, refer to Figure 5 The electric table top device also includes a second bushing 82; the first rotating arm 4 is provided with a first mounting hole, the second rotating shaft 71 is passed through the first mounting hole, and the second rotating shaft 71 can rotate relative to the first rotating arm 4, the second bushing 82 is provided in the first mounting hole, and the second rotating shaft 71 is passed through the second bushing 82.

[0088] Specifically, the second rotating shaft 71 is passed through the first rotating arm 4 and the mounting hole of the second rotating arm 3226, the second rotating shaft 71 is fixed in the mounting hole of the second rotating arm 3226, and the second rotating shaft 71 can rotate relative to the first rotating arm 4, that is, the second rotating arm 3226 is rotatably connected to the first rotating arm 4 through the second rotating shaft 71. A second bushing 82 is provided between the second rotating shaft 71 and the first mounting hole of the first rotating arm 4. The second rotating shaft 71 can rotate relative to the second bushing 82, and the second bushing 82 is fixed in the first mounting hole of the first rotating arm 4.

[0089] Optionally, refer to Figure 8 and Fig. 9 The driving member 2 includes a driving motor 22, a worm 23, a worm wheel 24 and a power output shaft 21; the worm 23 is connected to the power output end of the driving motor 22, the worm wheel 24 is meshed with the worm 23, one end of the power output shaft 21 is connected to the worm wheel 24, and the other end of the power output shaft 21 is connected to the first rotating shaft 311.

[0090] Specifically, the power output end of the driving member 2 is connected to a worm gear transmission mechanism, the worm 23 is connected to the motor, the worm wheel 24 is connected to one end of the power output shaft 21, and the other end of the power output shaft 21 is connected to the first rotating shaft 311. The axes of the worm 23 and the worm wheel 24 are orthogonal, realizing the orthogonal transformation of the rotation direction of the output end of the driving motor 22.
