Detailed Description
The invention will be further explained with reference to the drawings.
Fig. 1 is a perspective view of an embodiment of a maintenance base for a display device according to the present invention. As shown in fig. 1, a maintenance base 10 for a display device includes a first frame 1 and a second frame 2 parallel to and spaced apart from the first frame 1. The first frame 1 is used to fix with a wall or other vertical object, and the second frame 2 is used to fixedly mount the display device. The first frame 1 and the second frame 2 are each formed by connecting a plurality of beams and columns to each other. The overall outer shape of the first frame 1 and the second frame 2 may be cylindrical or prismatic. In a preferred embodiment, the first frame 1 has a larger size than the second frame 2, so that the first frame 1 can accommodate the second frame 2, contributing to a more compact structure of the maintenance base 10.
As shown in fig. 1 and 2, the maintenance base 10 further includes a telescopic bracket 3 provided between the first frame 1 and the second frame 2 and adapted to engage the first frame 1 and the second frame 2. The telescopic bracket 3 is configured to allow the second frame 2 to make a movement away from or close to the first frame 1 and to follow the second frame 2 to make an extension movement or a contraction movement. Wherein, the telescopic bracket 3 can be a link mechanism or a track mechanism.
In this embodiment, the telescopic bracket 3 includes a first swing lever 31 and a second swing lever 32 which intersect and are hinged to each other. The first and second swinging levers 31 and 32 which intersect each other are substantially in the shape of an "X", and the intersection of the two is the position of the hinge axis. The top end 31a of the first swing lever 31 is hinged to the first frame 1, and the bottom end 31b of the first swing lever 31 is hinged to a first sliding pair 33 provided on the second frame 2 and slidable in the vertical direction V. Similarly, the top end 32a of the second swing lever 32 is hinged to the second frame 2, and the bottom end 32b of the second swing lever 32 is hinged to a second sliding pair 34 provided on the first frame 1 and capable of sliding in the vertical direction V. In order to allow a smooth movement of the second frame 2, the number of telescopic supports 3 is two, the two telescopic supports 3 being parallel to each other and spaced apart, see in detail fig. 1.
In this embodiment, the first sliding pair 33 includes a first kidney-shaped hole 331 provided on the second frame 2 and distributed along the vertical direction V, and a first moving hinge shaft 332 provided in the first kidney-shaped hole 331. Meanwhile, the second moving pair 34 includes a second kidney-shaped hole 341 provided on the first frame 1 and distributed in the vertical direction V, and a second moving hinge shaft 342 provided in the second kidney-shaped hole 341. Wherein the first swing lever 31 is directly hinged to the first moving hinge shaft 332, and the second swing lever 32 is directly hinged to the second moving hinge shaft 342. The sliding pair used in the embodiment has a simple and compact structure, and can be conveniently and directly hinged with the corresponding swinging rod.
When the second frame 2 moves away from the first frame 1 (extension movement for short), an included angle between the first swing rod 31 and the second swing rod 32 toward the first frame 1 gradually decreases, the first swing rod 31 drives the first sliding pair 33 to move upward along the vertical direction V, and the second swing rod 32 drives the second sliding pair 34 to move upward along the vertical direction V. When the second frame 2 moves close to the first frame 1 (for short, shrinking movement), the included angle between the first swing rod 31 and the second swing rod 32 toward the first frame 1 gradually increases, the first swing rod 31 drives the first sliding pair 33 to move downward along the vertical direction V, and the second swing rod 32 drives the second sliding pair 34 to move downward along the vertical direction V.
The maintenance base 10 further includes a screw assembly 5 disposed between the first frame 1 and the second frame 2 for connecting the first frame 1 and the second frame 2, and a power mechanism 6 disposed on the first frame 1 or the second frame 2. The power mechanism 6 is configured to drive the second frame 2 to move towards or away from the first frame 1 through the lead screw assembly 5, so that the telescopic bracket 3 can perform an extending motion or a retracting motion along with the second frame 2. When the display device needs to be repaired and maintained, the maintenance base 10 can push out the second frame 2 with the display device through the action of the power mechanism 6, so that the maintenance personnel can conveniently repair and maintain the display device.
As shown in fig. 1 and 3, the lead screw assembly 5 includes a shaft seat 51 provided on one of the first frame 1 and the second frame 2, a rotating nut 52 partially provided in the shaft seat 51, and a lead screw 53 fixedly provided on the other of the first frame 1 and the second frame 2 and capable of cooperating with the rotating nut 52. The shaft seat 51 is disposed on the first frame 1, and the power mechanism 6 includes a motor 61 disposed on the first frame 1 and a belt transmission assembly 62 for connecting the exposed portion 52b of the rotating nut 52 and the motor 61. It is easy to understand that the shaft seat 51 and the motor 61 can be fixedly arranged on the first frame 1 and the second frame 2 at the same time, and the fixed connection can be selected from conventional fixed connections such as bolt connection and riveting connection.
Specifically, the belt transmission assembly 62 includes a pulley 621 provided on the output shaft of the motor 61, a pulley 622 provided on the exposed portion 52b of the rotating nut 52, and a belt 623 connecting the pulley 621 and the pulley 622. To increase the tension of the belt 623, a tensioner 624 may be provided on the first frame 1.
After the motor 61 is rotated, the motor 61 can drive the rotating nut 52 to rotate in the shaft seat 51 through the belt transmission assembly 62, and push the lead screw 53 to move forward (i.e. away from the first frame 1) or backward (i.e. close to the first frame 1). The maximum moving distance of the lead screw of the conventional lead screw assembly with respect to the lead screw nut is substantially equal to the length of the lead screw thread, and the maximum moving distance of the lead screw 53 of the lead screw assembly 5 of the present embodiment with respect to the turning nut 52 is substantially equal to twice the length of the thread of the lead screw 53. Compared with the traditional lead screw assembly, the lead screw assembly 5 can push the second frame 2 to be far away from the first frame 1, so that the operation space of maintenance personnel is enlarged, maintenance can be facilitated, and the maintenance efficiency is improved.
In the embodiment shown in FIG. 3, the axle seat 51 includes two open ends 511 and a sidewall 512 formed between the two open ends 511. The protruding portion 52a of the rotating nut 52 is provided in the side wall 512 and engages with the inner surface of the side wall 512 via a bearing 513. Since the protruding portion 52a of the rotating nut 52 is engaged with the side wall 512 via the bearing 513, the rotating nut 52 can rotate smoothly in the side wall 512 of the shaft seat 51, thereby reducing the loss of power due to friction.
In a preferred embodiment, the number of screw assemblies 5 is two, the screws of the two screw assemblies 5 being parallel and spaced apart, see fig. 1 in detail. It will be readily appreciated that the two parallel and spaced apart screw assemblies 5 ensure a smooth movement of the second frame 2, preventing the display device from colliding with nearby objects, thereby ensuring the safety of the display device. The two screw rod assemblies 5 are driven by one power mechanism 6, so that the screw rods 53 of the two screw rod assemblies 5 can synchronously rotate on the basis of saving cost.
In a preferred embodiment, a travel switch 6 for limiting the extension displacement of the second frame 2 is provided below the first kidney-shaped hole 331 and/or the second kidney-shaped hole 341, as shown in detail in fig. 2. The stroke switch 6 may be associated with the motor through a controller (e.g., a computer or a PLC) in the maintenance device 10, and when the first moving hinge shaft 332 and/or the second moving hinge shaft 342 contact the corresponding stroke switch 6, the controller (not shown) may control the motor to stop rotating or reverse rotating for the purpose of limiting the extension displacement of the second frame 2. The controller is known in the art and will not be described in detail herein.
In summary, the maintenance base 10 can push out the second frame 2 with the display device through the power mechanism 6, so that the maintenance personnel can perform maintenance on the display device conveniently.
While the invention has been described with reference to a preferred embodiment, various modifications may be made and equivalents may be substituted for elements thereof without departing from the scope of the invention. In particular, the technical features mentioned in the embodiments can be combined in any way as long as there is no structural conflict. It is intended that the invention not be limited to the particular embodiments disclosed, but that the invention will include all embodiments falling within the scope of the appended claims.
