[0041] The following is a detailed description with reference to the accompanying drawings and embodiments:

[0042] See also Figure 1 , an embodiment of the present application provides an adjustment device 10 for adjusting a part to be adjusted. For example, when the adjustment device 10 is applied to an electric screen, a display screen 20 can be installed on the adjustment device 10 to adjust the display screen 20 to a position suitable for viewing by a user. In addition, the adjustment device 10 can also be applied to adjust other parts to be adjusted, such as a lamp body, a door, a panel, etc. It can be understood that the part to be adjusted can be, but is not limited to, a display screen 20, a lamp body, a door, and a panel.

[0043] In one embodiment of the present application, see Figures 1 to 3 The adjusting device 10 includes a housing 11, a driving mechanism 12 and a guide structure 13. The housing 11 is provided with a guide groove 111, and at least a portion of the guide groove 111 is arranged in an arc shape. The driving mechanism 12 is used to be rotatably connected to the part to be adjusted to drive the part to be adjusted to move. The guide structure 13 is slidably arranged in the guide groove 111 and is used to connect the part to be adjusted. In the process of the driving mechanism 12 driving the part to be adjusted to move, the guide structure 13 slides in an arc shape along the guide groove 111 to guide the movement of the part to be adjusted.

[0044] The guide groove 111 may have all its groove sections arranged in an arc shape; or, the guide groove 111 may have a part of its groove sections arranged in an arc shape, while another part of its groove sections are not in an arc shape but are in a straight line.

[0045] In one implementation, the guide structure 13 can be fixedly installed on the part to be adjusted by means of snap-fitting, bonding, etc.; or, in another implementation, the guide structure 13 can also be integrally formed with the part to be adjusted by means of casting, injection molding, etc.

[0046] The guide structure 13 may be a rod-shaped structure, connected to the to-be-adjusted member and the housing 11. Specifically, a convex column, a convex block or the like may be provided at one end of the guide structure 13 close to the guide groove 111 of the housing 11, so that the guide structure 13 can extend into the guide groove 111 and slide along the guide groove 111.

[0047] The adjusting device 10 provided in the embodiment of the present application, when the adjusting device 10 is used, the driving mechanism 12 is rotated to connect the part to be adjusted, and can drive the part to be adjusted to move. The housing 11 is provided with a guide groove 111 that is at least partially arc-shaped, and the guide structure 13 is connected to the part to be adjusted. When the part to be adjusted moves under the drive of the driving mechanism 12, the guide structure 13 connected to the part to be adjusted can slide in an arc along the guide groove 111, so that the part to be adjusted is also guided by the guide structure 13 when it moves under the drive of the driving mechanism 12, and then the part to be adjusted can move along an arc trajectory. At the same time, the part to be adjusted itself can also adaptively deflect relative to the driving mechanism 12, that is, when the driving mechanism 12 moves, the part to be adjusted is guided by the guide structure 13 and can deflect relative to the driving mechanism 12. In this way, the part to be adjusted can move along an arc trajectory and can also adaptively swing relative to the driving mechanism 12 under the drive of the driving mechanism 12, so that the part to be adjusted can be directly adjusted to a position suitable for the user to watch, eliminating the adjustment steps of the adjustment device 10 to extend and rotate, greatly simplifying the adjustment steps of the adjustment device 10, and saving the adjustment time of the adjustment device 10.

[0048] In one embodiment, the guide groove 111 is disposed below the housing 11 in the vertical direction and is open in the vertical downward direction. The inner wall surface of the guide groove 111 is provided with a slot (not shown) that matches the guide structure 13. When the guide structure 13 extends into the guide groove 111, the portion of the guide structure 13 extending into the guide groove 111 can be limited to the inner wall surface of the slot in the vertical direction, so that the guide structure 13 is not easy to separate from the guide groove 111 in the vertical direction under the action of gravity, thereby improving the sliding stability of the guide structure 13 in the guide groove 111.

[0049] In one embodiment of the present application, see Figure 1 and Figure 2, the number of the driving mechanisms 12 is two. The two driving mechanisms 12 are used to alternately drive the part to be adjusted. Among them, the two driving mechanisms 12 are respectively a first driving mechanism 12a and a second driving mechanism 12b. The guide groove 111 includes a first groove section 1111 and a second groove section 1112. The first groove section 1111 and the second groove section 1112 are interconnected and relatively bent. At least a portion of the first groove section 1111 is arranged in an arc shape, and at least a portion of the second groove section 1112 is also arranged in an arc shape. In the process of the first driving mechanism 12a driving the part to be adjusted to move, the guide structure 13 slides along the first groove section 1111. In the process of the second driving mechanism 12b driving the part to be adjusted to move, the guide structure 13 slides along the second groove section 1112.

[0050] The first slot section 1111 may be arranged in an arc shape in its entirety; or, the first slot section 1111 may be arranged in an arc shape in part and in another part. The shape of the second slot section 1112 may be obtained in a similar manner.

[0051] During the use of the adjustment device 10, the first driving mechanism 12a is controlled to drive the member to be adjusted to move. During the movement, the member to be adjusted will also drive the guide structure 13 to move along the first slot section 1111 of the guide slot 111. The first slot section 1111 is provided with an arc-shaped portion, so that the member to be adjusted can make a swinging motion along the first slot section 1111. Since the first slot section 1111 and the second slot section 1112 are connected to each other, when the member to be adjusted drives the guide structure 13 to move along the first slot section 1111 to the connection between the first slot section 1111 and the second slot section 1112, the first driving mechanism 12a can be stopped and switched to the second driving mechanism 12b to drive the member to be adjusted, so that the second driving mechanism 12b drives the member to be adjusted to move. During the movement, the member to be adjusted will drive the guide structure 13 to move along the second slot section 1112 of the guide slot 111. The second slot section 1112 is provided with an arc-shaped portion, so that the member to be adjusted can make a swinging motion along the second slot section 1112. In actual use, the first driving mechanism 12a and the second driving mechanism 12b can be alternately driven to make the adjusted member alternately switch to the swinging motion along the first slot section 1111 and the second slot section 1112.

[0052] In this way, the two driving mechanisms 12 alternately drive the adjustable part, so that the adjustable part can alternately switch to different deflection trajectories, expanding the adjustment range of the adjustable part, so that the adjustable part can be adjusted along two different trajectories to multiple positions suitable for user viewing, thereby improving the adjustment flexibility of the adjustment device 10.

[0053] In one embodiment of the present application, see Figure 1 and Figure 2, the first driving mechanism 12a and the second driving mechanism 12b are sequentially distributed along the first direction X. The first slot section 1111 and the second slot section 1112 are sequentially distributed along the first direction X. One end of the first slot section 1111 along the second direction Y and one end of the second slot section 1112 along the second direction Y are connected to each other. The spacing between the first slot section 1111 and the second slot section 1112 in the first direction X is gradually expanded away from the connection between the first slot section 1111 and the second slot section 1112 along the second direction Y. The first direction X and the second direction Y are perpendicular.

[0054] In one possible design, the distribution direction of the first slot segments 1111 and the second slot segments 1112 along the first direction X is opposite to the distribution direction of the first drive mechanism 12a and the second drive mechanism 12b along the first direction X. In another possible design, the distribution direction of the first slot segments 1111 and the second slot segments 1112 along the first direction X is the same as the distribution direction of the first drive mechanism 12a and the second drive mechanism 12b along the first direction X.

[0055] Along the second direction Y from the connection point between the first slot segment 1111 and the second slot segment 1112 toward a direction away from the connection point, the distance between the first slot segment 1111 and the second slot segment 1112 in the first direction X gradually increases.

[0056] It can be understood that when the first driving mechanism 12a drives the member to be adjusted to move, the member to be adjusted can drive the guide structure 13 to slide from the connection between the first slot section 1111 and the second slot section 1112 to the other end of the first slot section 1111 along the second direction Y, and can also drive the guide structure 13 to slide along the first slot section 1111 back to the connection between the first slot section 1111 and the second slot section 1112. When the second driving mechanism 12b drives the member to be adjusted to move, the member to be adjusted can drive the guide structure 13 to slide from the connection between the first slot section 1111 and the second slot section 1112 to the other end of the second slot section 1112 along the second direction Y, and can also drive the guide structure 13 to slide along the second slot end back to the connection between the first slot section 1111 and the second slot section 1112.

[0057] Wherein, the first direction X is as follows Figure 1 The direction X shown in the figure, the second direction Y is as follows Figure 1 The direction Y indicated in the figure, Figure 1 The direction Z is also indicated in the figure. The directions X, Y and Z are the directions of the three coordinate axes in the space coordinate system, that is, the direction X is perpendicular to the direction Y, the direction X is perpendicular to the direction Z, and the direction Y is perpendicular to the direction Z.

[0058] In this way, the first driving mechanism 12a and the second driving mechanism 12b can respectively drive the adjustable part to perform a yaw motion in opposite directions along the first direction X, further expanding the adjustment range of the adjustable part in the first direction X, so that the adjustable part can be adjusted to different positions suitable for the user to watch, thereby improving the adjustment flexibility of the adjustment device 10.

[0059] In one embodiment of the present application, see Figures 1 to 3 The driving mechanism 12 includes a connecting rod structure 122 and a driving structure 121. The connecting rod structure 122 includes a plurality of connecting rods, which are rotatably connected in sequence. The connecting rods at both ends of the connecting rod structure 122 are respectively a first connecting rod 1221 and a second connecting rod 1222. The first connecting rod 1221 is rotatably connected to the member to be adjusted. The driving structure 121 is connected to the second connecting rod 1222 and is used to drive the connecting rod structure 122 to move.

[0060] In one possible design, the connecting rod structure 122 includes two connecting rods that are rotatably connected in sequence, that is, a first connecting rod 1221 and a second connecting rod 1222. Alternatively, in another possible design, the connecting rod structure 122 includes more than three connecting rods that are rotatably connected in sequence, and two adjacent connecting rods are rotatably connected. The connecting rod at one end of the connecting rod structure 122 is the first connecting rod 1221, and the connecting rod at the other end is the second connecting rod 1222.

[0061] In the process of the driving structure 121 driving the second connecting rod 1222 to move, the second connecting rod 1222 can ultimately drive the first connecting rod 1221 to rotate, and can also drive the first connecting rod 1221 to move relative to the outer shell 11. Since the first connecting rod 1221 is rotatably connected to the part to be adjusted, the first connecting rod 1221 can drive the part to be adjusted to rotate, and can also drive the part to be adjusted to move relative to the outer shell 11.

[0062] Through the rotational connection between the multiple connecting rods, the driving structure 121 can drive the first connecting rod 1221 to move by only driving the second connecting rod 1222, and then drive the adjustable member to move through the first connecting rod 1221. In this way, the connecting rod structure 122 provides a multi-directional driving force for the adjustable member, so that the adjustable member can move along a reliable trajectory to a position suitable for the user, thereby improving the reliability of adjusting the adjustable member.

[0063] In one embodiment, the rotation axes of the multiple connecting rods and the rotation axis of the first connecting rod 1221 relative to the part to be adjusted are parallel to each other. In this way, the wear of the connecting rods during relative rotation is reduced, and the wear of the part to be adjusted during rotation relative to the first connecting rod 1221 is also reduced, and the driving structure 121 drives the part to be adjusted more smoothly.

[0064] In one embodiment of the present application, see Figures 1 to 3The adjusting device 10 further includes a limiting structure 14. The limiting structure 14 is disposed on the housing 11. The limiting structure 14 is disposed on the motion track of at least one connecting rod to limit the travel of the member to be adjusted toward the housing 11.

[0065] It can be understood that when the connecting rod abuts against the limiting structure 14 during rotation, the limiting structure 14 can limit the rotational movement of the connecting rod, and the connecting rod cannot drive the adjacent connecting rod or the part to be adjusted to move, so that the movement of the first connecting rod 1221 relative to the outer shell 11 is restricted, and the part to be adjusted cannot continue to move relative to the outer shell 11.

[0066] In a possible design, the limiting structure 14 includes two limiting protrusions 141, and the two limiting protrusions 141 are spaced apart and distributed on the rotation track of the connecting rod, so that the connecting rod can be limited and abutted against the two limiting protrusions 141 in the clockwise direction and the counterclockwise direction, respectively. Alternatively, in another possible design, the limiting structure 14 can also be an integral structure, and the limiting structure 14 is arranged on the rotation track of the connecting rod, so that the connecting rod can be limited to the limiting structure 14 when moving in the clockwise direction and the counterclockwise direction.

[0067] In this way, the movement stroke of the adjustable part toward the housing 11 can be limited to prevent the adjustable part from hitting the housing 11 of the adjusting device 10 during movement, thereby reducing the risk of damage to the adjustable part during adjustment.

[0068] In one embodiment of the present application, see Figures 1 to 4 The driving structure 121 includes a driving member 1211, a transmission assembly 1212 and a rotating member 1213. The transmission assembly 1212 is disposed at the output end of the driving member 1211. The rotating member 1213 is disposed at the transmission assembly 1212 and is capable of rotating. The second connecting rod 1222 is connected to the rotating member 1213 to rotate with the rotating member 1213.

[0069] The driving member 1211 may be, but is not limited to, a motor, and the motor can be connected to an external power source.

[0070] In a possible design, the transmission assembly 1212 includes a parallel gear set 12121 disposed at the output end of the driving member 1211, the gears in the parallel gear set 12121 mesh with each other for transmission, and a worm 12122 may also be provided at the output end of the parallel gear set 12121, and the parallel gear set 12121 drives the worm 12122 to rotate. The transmission assembly 1212 also includes a helical gear 12123, which is sleeved on the rotating member 1213, and the helical gear 12123 meshes with the above-mentioned worm 12122 for transmission, so that the helical gear 12123 can rotate under the drive of the worm 12122. In this way, the rotating member 1213 can rotate with the helical gear 12123. Of course, the transmission assembly 1212 is not limited to the above scheme, and can also be in other forms.

[0071] The second connecting rod 1222 can be fixed to the rotating member 1213 by means of clamping, bonding, bolt connection, etc., so as to rotate along with the rotating member 1213 .

[0072] In this way, the rotating member 1213 is not directly mounted on the driving member 1211, but is connected to the driving member 1211 through the transmission assembly 1212, so that the transmission of the rotating member 1213 is more stable and reliable, and the transmission efficiency is high, which is conducive to the rotating member 1213 to stably drive the second connecting rod 1222 to rotate. At the same time, the components inside the transmission assembly 1212 are meshed and transmitted, which increases the service life of the transmission assembly 1212.

[0073] When the rotating member 1213 rotates, the second connecting rod 1222 rotates with the rotating member 1213, and drives the connecting rod connected thereto to rotate, and finally drives the first connecting rod 1221 to rotate. The rotation axis L of the rotating member 1213 is parallel to the rotation axes of the multiple connecting rods, and is also parallel to the rotation axis of the member to be adjusted relative to the first connecting rod 1221. In this way, the member to be adjusted can be simply adjusted by the rotation of the rotating member 1213, which improves the controllability of the connecting rod structure 122, and further improves the working efficiency of the adjusting device 10.

[0074] In one embodiment of the present application, see Figure 3 and Figure 4 The driving structure 121 further includes a bearing 1214. The outer ring of the bearing 1214 is fixed to the housing 11, and the inner ring of the bearing 1214 is sleeved on the rotating member 1213 and has a clearance fit with the rotating member 1213.

[0075] It can be understood that a lubricating oil film layer is provided on the surface where the bearing 1214 and the rotating member 1213 are in sliding contact, thereby reducing the friction resistance encountered by the rotating member 1213 when rotating.

[0076] When part of the transmission assembly 1212 is sleeved on the rotating member 1213, the inner ring of the bearing 1214 is sleeved on the rotating member 1213, and the outer ring of the bearing 1214 abuts against the transmission assembly 1212 on two opposite sides along the extending direction of the rotation axis L of the rotating member 1213, so as to support the transmission assembly 1212. As an example, the transmission assembly 1212 includes a bevel gear 12123, which is sleeved on the rotating member 1213, and two bearings 1214 are provided, and the two bearings 1214 abut against the bevel gear 12123 on two opposite sides along the extending direction of the rotation axis L of the rotating member 1213.

[0077] In this way, the bearing 1214 is sleeved on the rotating member 1213, which reduces the friction of the rotating member 1213 during rotation, making the rotation of the rotating member 1213 smoother and reducing the wear of the rotating member 1213 during rotation. At the same time, the bearing 1214 can also support the transmission assembly 1212 located on the rotating member 1213, making the transmission of the transmission assembly 1212 more stable.

[0078] Alternatively, in another embodiment, the driving structure 121 further includes a damping sleeve 1215. The damping sleeve 1215 is fixed to the housing 11 and sleeved on the rotating member 1213. The damping sleeve 1215 is used to provide damping for the rotation of the rotating member 1213.

[0079] The damping sleeve 1215 can be selected as a plastic sleeve, a rubber sleeve, etc.

[0080] The outer circumference of the damping sleeve 1215 can be fixed to the housing 11 by means of clamping, bonding, etc., and the inner circumference of the damping sleeve 1215 is interference fit with the rotating member 1213 .

[0081] In this way, the damping sleeve 1215 can provide enough friction force for the rotating member 1213, so that the rotating member 1213 can rotate more smoothly during the rotation process. At the same time, the damping sleeve 1215 provides a good holding force for the rotating member 1213 when the rotating member 1213 does not rotate.

[0082] Alternatively, in another embodiment, the driving structure 121 may include the above-mentioned bearing 1214 and damping sleeve 1215 at the same time. The outer ring of the bearing 1214 is fixed to the housing 11, and the inner ring of the bearing 1214 is sleeved on the rotating member 1213 and has a clearance fit with the rotating member 1213. The damping sleeve 1215 is fixed to the housing 11 and sleeved on the rotating member 1213. The bearing 1214 and the damping sleeve 1215 may be arranged at intervals on the rotating member 1213 along the third direction Z; or, the bearing 1214 and the damping sleeve 1215 may also abut against each other along the third direction Z.

[0083] In this way, the rotating member 1213 can reduce friction through the bearing 1214 and can also be subjected to friction from the damping sleeve 1215, so that the friction force exerted on the rotating member 1213 during rotation is stable, which is conducive to the stable rotation of the rotating member 1213 and also enables the rotating member 1213 to remain stationary when not driven.

[0084] In one embodiment of the present application, see Figures 3 to 5 The adjusting device 10 further includes a detection device 15. The detection device 15 is disposed on the housing 11 and is used to detect the rotation angle of the rotating member 1213.

[0085] The detection device 15 may be, but is not limited to, an angle encoder.

[0086] During operation, the rotating member 1213 rotates under the drive of the transmission assembly 1212 , and the detection device 15 is mainly used to detect and identify the rotation angle of the rotating member 1213 , and convert the obtained angle information into an electrical signal to feed back to an external control unit.

[0087] In this way, the user can control the rotation speed of the driving member 1211 through the angle information detected by the detection device 15, thereby achieving precise control of the rotation of the rotating member 1213, and further accurately controlling the adjustment speed of the member to be adjusted.

[0088] In one embodiment of the present application, see Figure 3 and Figure 4 , part of the transmission assembly 1212 is sleeved on the rotating member 1213, and is used to drive the rotating member 1213 to rotate. The driving structure 121 also includes an elastic member 1216. In the third direction Z, the elastic member 1216 is arranged between the transmission assembly 1212 and the bearing 1214. The elastic member 1216 is used to provide elastic force to the transmission assembly 1212 and the bearing 1214. The third direction Z is parallel to the rotation axis L of the rotating member 1213.

[0089] In a possible design, the portion of the transmission assembly 1212 sleeved on the rotating member 1213 may be a bevel gear 12123, and the other portions of the transmission assembly 1212 are used to connect to the driving member 1211 and can mesh with the bevel gear 12123 for transmission, so that the bevel gear 12123 can rotate.

[0090] The elastic member 1216 may be a structure such as a spring or a spring sheet that can generate elastic force. As an example, the elastic member 1216 may be a wavy spring sheet that provides elastic force to the transmission assembly 1212 and the bearing 1214 by deforming along the third direction Z.

[0091] The rotation axis L is as follows: Figure 4 The axis L shown in the figure, the third direction Z is as follows Figure 4 The Z axis shown in the figure, the third direction Z is parallel to the rotation axis L.

[0092] By setting the elastic member 1216, the elastic member 1216 can generate pressure along the third direction Z, so that the transmission component 1212 and the bearing 1214 located on the rotating member 1213 are both subjected to the elastic force of the elastic member 1216, thereby further reducing the axial clearance between the transmission component 1212 and the bearing 1214, and reducing the risk of axial movement of the transmission component 1212 and the bearing 1214 along the third direction Z on the rotating member 1213.

[0093] In one embodiment, gaskets 1217 may be provided on opposite sides of the elastic member 1216 along the third direction Z. The gaskets 1217 are also mounted on the rotating member 1213 and pressed against opposite sides of the elastic member 1216 along the third direction Z to ensure the stability of the elastic member 1216 during deformation and reduce the possibility of the elastic member 1216 being skewed during deformation.

[0094] According to the electric screen of the second embodiment of the present application, the electric screen includes a display screen 20 and an adjustment device 10. The guide structure 13 of the adjustment device 10 is connected to the display screen 20. At the same time, the driving mechanism 12 of the adjustment device 10 is rotationally connected to the display screen 20.

[0095] Among them, the adjustment device 10 involved in this embodiment is the same as the adjustment device 10 involved in the above embodiment. For details, please refer to the relevant description above and will not be repeated here.

[0096] In the electric screen provided in the embodiment of the present application, the driving mechanism 12 is rotatably connected to the display screen 20 and can drive the display screen 20 to move. The guide structure 13 is connected to the display screen 20. When the display screen 20 moves under the drive of the driving mechanism 12, the guide structure 13 connected to the display screen 20 can slide in an arc along the guide groove 111 to guide the movement of the display screen 20, so that the display screen 20 can move along the arc track. At the same time, the display screen 20 itself can also be adaptively deflected relative to the driving mechanism 12. In this way, the display screen 20 can move along the arc track, and can also be adaptively deflected relative to the driving mechanism 12 under the drive of the driving mechanism 12, so that the display screen 20 can be directly adjusted to a position suitable for the user to watch, eliminating the adjustment steps of the adjustment device 10 to extend and rotate, greatly simplifying the adjustment steps of the adjustment device 10, and saving the adjustment time of the adjustment device 10.

[0097] The above are only preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
