Description

Technical Field

[0001] The invention belongs to the technical field of display of wallpaper, wall cloth, scroll, curtain and the like, and in particular relates to an intelligent display machine. Background Art

[0002] The most commonly used method for displaying wallpaper, wall cloth, scrolls, curtains, etc. is manual. Taking the commonly used method of displaying calligraphy and painting as an example, the scroll is mainly displayed by manually pulling it down, and then fixing its bottom to achieve the purpose of display. When it is retracted, it is manually rolled back, which is both time-consuming and laborious. Another method is to set a spiral spring on the scroll. When it is pulled down, the spring is tightened and self-locked at any time for display; when it is retracted, the scroll is rolled back through the release of spring potential energy, which is more efficient than manual rewinding. However, with the increasing frequency of use, the spring in the scroll is prone to fatigue, resulting in the inability to effectively retract the scroll. In addition, such a display requires a large space for layout when there are many items to be displayed, which is particularly unsuitable for the display and sale of wallpaper, wall cloth, curtains and other items.

[0003] In the prior art, there are also corresponding display devices that can achieve good display effects. For example, the patent document with publication number CN110051179A discloses a circulating transmission display machine, including a chassis, the chassis includes side panels, an upper cover plate, a rear cover plate, a front cover plate and a bottom plate, a motor is provided in the chassis, a circulating transmission mechanism driven by a motor is provided at the side panel of the display machine, a display reel is installed on the upper part of the chassis, and a button connection device and a button connection tightening device are respectively provided at both ends of the display reel, the button connection device and the button connection tightening device are both connected to the circulating transmission mechanism, and the button connection tightening device is also connected to the tightening component of the display item reel. The display items on the reel of the circulating transmission display machine can be pulled open when they need to be displayed, and after the display is completed, they are automatically retracted by connecting the button connection tightening device to the tightening component; however, when they need to be displayed, the display items on the reel need to be pulled out manually, which has a low degree of intelligence and low efficiency.

[0023] In order to more clearly illustrate the embodiments of the present invention, the specific embodiments of the present invention will be described below with reference to the accompanying drawings. Obviously, the drawings described below are only some embodiments of the present invention. For those of ordinary skill in the art, other drawings and other embodiments can be obtained based on these drawings without creative work. In addition, the directional terms mentioned in the following embodiments, such as up, down, left, right, front or back, etc., are only reference directions of the drawings. Therefore, the directional terms used are used to illustrate and not to limit the present invention.

[0024] Embodiment 1:

[0025] like Figure 1-3As shown, the intelligent display machine of this embodiment includes a chassis and a driving motor 16 installed in the chassis, a circulating transmission mechanism, a reel motor approaching mechanism 19 and a reel power motor 21.

[0026] Specifically, the chassis includes a side panel 1, an upper cover 2, a back panel 17, a front panel 18 and a bottom panel 14, which are a hollow three-dimensional structure formed by the side panel 1, the upper cover 2, the back panel 17, the front panel 18 and the bottom panel 14. Figure 2 As shown, the top of the front panel 18 has an outer protrusion 18c and an inner concave hollow window 18a. The outer protrusion 18c is the position where the exhibit is extended. The outer protrusion can make the exhibit of the display roll at the target display position extend smoothly and automatically to avoid collision with the position of the front panel 18. After the display is over, it can automatically retract to the roll. The inner concave hollow window 18a makes it easy to install the display roll containing the exhibit from the position of the inner concave hollow window to the circulating transmission mechanism. Among them, the target display position is located above the inner concave hollow window, that is, the position of the outer protrusion 18c. In addition, as Figure 2 As shown, the bottom of the concave hollow window 18a has a guiding arc surface 18b so that the extended exhibits can be quickly extended to the bottom of the case.

[0027] A driving motor 16 is installed near the bottom of the chassis. The driving motor 16 is installed in the chassis through a motor support and a transmission component 15 and drives a circulating transmission mechanism. The circulating transmission mechanism is arranged along the height direction of the chassis to form a circulating transmission path. Among them, the circulating transmission mechanism can be a chain transmission mechanism, a belt transmission mechanism, or other commonly used transmission mechanisms in the prior art. Here, only the chain transmission mechanism is used as an example for detailed description. Other transmission mechanisms can refer to the chain transmission mechanism and are not described in detail.

[0028] The circulating transmission mechanism of this embodiment is a double-sided synchronous drive structure. Figure 2 As shown, each side includes a large sprocket assembly 12 and six small sprocket assemblies 10 arranged along the transmission path, wherein four small sprocket assemblies are located at the top of the chassis, and the other two small sprocket assemblies are located at the bottom of the chassis; the large sprocket assembly 12 is located in the area enclosed by the six small sprocket assemblies and is installed close to the small sprocket assembly at the bottom, and in addition, the large sprocket assembly is located on the central axis between the two small sprocket assemblies at the bottom. The large sprocket assembly corresponding to the left side and the six small sprocket assemblies are connected by the left chain 9, and the large sprocket assembly corresponding to the right side and the six small sprocket assemblies are connected by the right chain 23. The double-sided synchronous drive enables the display machine to have a double-sided display function, doubling the display volume. Among them, the drive motor 16 is equipped with a reducer (motor with synchronous reduction device), which has the function of synchronous driving on both sides; the drive motor 16 can synchronously drive the large sprocket assembly to drive the chain transmission.

[0029] like Figure 1 As shown, the two ends of the display reel 4 are respectively installed on the left chain 9 and the right chain 23, and multiple display reels are sequentially installed along the extension direction of the left chain and the right chain, so as to display a variety of exhibits and meet the needs of different displays. Among them, the left chain 9 and the right chain 23 have shafts at equal intervals, and the shafts of the chains on both sides are respectively connected to the display reel 4 through mechanical mechanisms. Specifically, the shaft of the right chain 23 is locked and connected with the reel gear transmission mechanism 22 through the chain lock plate connection device 3, and the reel gear transmission mechanism 22 is connected to the display reel 4. The display reel 4 has a reel running mechanism 20, which is used to link the reel to rotate, so as to extend or retract the exhibits of the display reel; the shaft of the left chain 9 is directly connected to the button connection device 5, and the button connection device 5 is connected to the display reel 4, so that the display reel 4 is connected to the left chain and the right chain to form a complete transmission display mechanism. Among them, the chain lock plate connection device 3 and the button connection device 5 can refer to the existing technology and will not be repeated here. The lock plate connection device 3, the reel gear transmission mechanism 22, and the button connection device 5 are installed at both ends of the display reel 4, and the display reel 4 can be quickly put in or taken out from the hanging left chain 9 and the right chain 23. The button connection device 5 has a functional mechanism design suitable for quickly installing or removing from the output shaft of the left chain 9 and preventing withdrawal. The right side of the display reel 4 also has a functional mechanism design for quickly installing or removing from the reel gear transmission mechanism 22. Therefore, the chain output shaft design can quickly hang or take out the display reel 4 through the lock plate connection device 3, the reel gear transmission mechanism 22, and the button connection device 5.

[0030] Among them, upper fixed beams 11 are respectively installed on the upper parts of both sides of the chassis, and four small sprocket assemblies 10 on the top of the chassis are installed on the upper fixed beams 11, among which the two small sprocket assemblies on the top are located at the position of the protrusion 18c of the front panel.

[0031] A tensioning adjustment device is provided corresponding to the left chain 9 and the right chain 23, respectively. The tensioning adjustment device includes a sprocket spring automatic adjustment mechanism 6 and an intermediate movable crossbeam 13. The intermediate movable crossbeam 13 is installed in the middle of the chassis, and the large sprocket assembly 12 is installed on the intermediate movable crossbeam 13. The two small sprocket assemblies 10 at the bottom are installed on the lower fixed crossbeam 8. The sprocket spring automatic adjustment mechanism 6 presses down the large sprocket assembly 12 to tighten the corresponding left chain or right chain. An adjustment baffle 7 is provided corresponding to the sprocket spring automatic adjustment mechanism 6 to prevent excessive adjustment when the chain is tightened.

[0032] After the chain has been used for a period of time, it is easy to deform and stretch. The chain tension can be tightened or adjusted by pressing down the position of the large sprocket assembly 12 through the sprocket spring automatic adjustment mechanism 6. The sprocket spring automatic adjustment mechanism 6 is a compression spring structure installed above the large sprocket assembly 12. When the chain is loose, the compression spring can automatically press down the large sprocket assembly 12, thereby achieving the function of adjusting the tightness of the chain. The left chain 9 and the right chain 23 can be automatically tightened and adjusted through the sprocket spring automatic adjustment mechanism 6 and the middle movable crossbeam 13 to ensure that the chain is always in a tensioned state during the transmission process.

[0033] The driving motor 16 drives the circular transmission mechanism, and the left chain and the right chain are connected to the display reel 4 through the locking plate connection device 3 and the button connection device 5 to realize synchronous linkage, and each display reel moves circularly along the transmission path of the chain and moves to the target display position in sequence. The display of the display reel 4 at the target display position can be automatically extended or automatically retracted through the reel power motor 21, the reel motor approaching mechanism 19, the reel gear transmission mechanism 22, and the reel running mechanism 20, and can realize automatic stop and lock at any time and any position when the display is extended.

[0034] Specifically, the reel gear transmission mechanism 22 is linked with the reel running mechanism 20, the reel motor approaching mechanism 19 and the reel power motor 21 are arranged in the chassis corresponding to the target display position, and the reel motor approaching mechanism 19 is used to drive the reel power motor 21 to move; when the reel power motor 21 moves to the working position, the reel power motor 21 is linked with the reel gear transmission mechanism 22; when the reel power motor moves to the non-working position, the linkage connection between the reel power motor 21 and the reel gear transmission mechanism 22 is disengaged. At this time, the display reel in the target display position can continue to be transmitted, waiting for the next display reel to be transmitted to the target display position, and the next display roll is displayed.

[0035] Among them, Figure 3 As shown, the scroll motor approaching mechanism 19 includes a telescopic motor 19a, a connecting rod 19b and a movable seat 19c, the motor shaft of the telescopic motor 19a is connected to one end of the connecting rod 19b by a rotating pair, the other end of the connecting rod 19b is connected to the movable seat 19c by a rotating pair, and the movable seat 19c is rotatably installed in the chassis; the scroll power motor 21 is installed on the movable seat 19c, the motor shaft of the scroll power motor 21 is installed with a first gear 21a, the scroll power motor 21 and the first gear 21a are located on both sides of the movable seat 19c, and the motor shaft of the scroll power motor 21 passes through the movable seat 19c and is transmission-connected to the first gear 21a.

[0036] The reel gear transmission mechanism 22 includes a transmission gear 22a, which is linked to the reel running mechanism. A transition gear 22b is provided between the transmission gear 22a and the first gear 21a, that is, the transmission gear 22a meshes with the transition gear 22b, and the transition gear 22b is used to mesh with the first gear 21a.

[0037] When the reel power motor 21 moves to the working position, the first gear 21a is meshed with the transition gear 22b.

[0038] When the reel power motor 21 moves to the non-operating position, the first gear 21 a is disengaged from the transition gear 22 b.

[0039] The outer diameter of the first gear is larger than that of the transmission gear and the transition gear, which is beneficial to the transmission of torque and reduces the power output of the reel power motor. In addition, the reel operating mechanism 20 can be a linkage shaft, which is respectively connected to the transmission gear and the rotating shaft of the display reel.

[0040] The drive motor 16 of this embodiment can rotate forward or reverse and has multiple speed adjustment gears. The drive motor can rotate forward and reverse, and can also rotate at fast, medium and slow speeds, so that the required display reel can be found in the shortest time, thereby efficiently displaying the exhibits.

[0041] The working principle of the intelligent display machine in this embodiment is:

[0042] Start the drive motor to synchronously drive the large sprocket assemblies on both sides to run, driving the chains on both sides to drive synchronously. When the required display reel moves to the target display position, control the drive motor to stop;

[0043] At this time, the reel power motor is in the non-working position, the telescopic motor is started, the connecting rod and the movable seat are linked in sequence, the movable seat links the reel power motor and the first gear to move to the working position, at this time, the first gear is meshed with the transition gear, and the telescopic motor is controlled to stop;

[0044] The reel power motor is started to drive the first gear to rotate, and the transition gear, the transmission gear, and the reel running mechanism are linked in sequence, so that the display reel rotates in a linked manner, and the display extends out of the concave hollow window of the front cover plate to the bottom of the chassis, and the reel power motor is controlled to stop, so that automatic display is realized;

[0045] After the display is over, the scroll power motor is controlled to reverse and the display items are automatically recovered.

[0046] When another display reel is needed for display, the telescopic motor is started, and the connecting rod and the movable seat are linked in sequence. The movable seat is linked to the reel power motor and the first gear to move to the non-working position. At this time, the first gear is disengaged from the transition gear, and the telescopic motor is controlled to stop; the driving motor is started to make the other display reel move to the target display position, and the above operations are repeated to realize automatic display and automatic recovery, and various exhibits can be displayed in turn.

[0047] The intelligent display machine of this embodiment realizes intelligent control of display based on Internet of Things technology.

[0048] Embodiment 2:

[0049] The difference between the smart display machine of this embodiment and the first embodiment is that:

[0050] The reel running mechanism of this embodiment has a self-locking mechanism, which can realize the extension, retraction and locking of the exhibits in the display reel at any time and in any position.

[0052] Embodiment three:

[0053] The difference between the smart display machine of this embodiment and the first embodiment is that:

[0054] In this embodiment, multiple transition gears can be arranged between the transmission gear and the first gear, or no transition gear is arranged and the transmission gear is directly linked to the first gear. The number of transition gears can be designed according to actual needs to meet different application scenarios.

[0055] For other structures, please refer to the first embodiment.

[0056] The above is only a detailed description of the preferred embodiments and principles of the present invention.
