Description

Technical Field

[0001] The present invention relates to a display device, and more particularly to a commodity display device that can be clamped at multiple angles. Background Art

[0002] Traditional offline commodity promotion currently mostly uses methods such as commodity display racks, jumping cards, and light boxes and screen advertisements. Although this traditional display method is common, it lacks novelty. With the emergence of more creative advertisements, the visual impact is gradually weakening, and the effect is not obvious enough.

[0003] In recent years, emerging interactive art has gradually entered the public eye, breaking through the traditional static display method. Using human interaction, dynamic sensing, and dynamic display methods for commodity promotion, replacing manual explanations and print advertisements, is a better way to display and promote commodities.

[0004] For example, Chinese Patent No. 202110480943.9 discloses a product display method and device. This patented application is one of the new automatic display devices. By arranging sensors on the shelves for human detection and dynamically displaying commodity entities through display devices, it realizes the interaction between commodities and people to a certain extent, achieving the effect of replacing manual labor and attracting attention and guiding traffic.

[0005] However, the above display device only realizes the dynamic display of commodities after sensing the human body. The displayed commodity is only the commodity itself, and it does not do more extended promotion for the same category of commodities of the merchant. There are certain limitations.

[0006] In addition to the basic commodity display function, this technology is also attached with an NFC live code label, which can remotely update display and promotion information, achieve near-field communication and interact with the mobile phone by the customer actively bringing the mobile phone closer, promote other commodities of the same category or similar categories of the same merchant, or receive coupons, issue electronic membership cards, trace commodity information, etc.

[0007] In terms of structure, the display device of the above patented application only realizes the movement of a fixed trajectory, and cannot be used for shelves with price tags and fences of a certain height, and can only be used for commodity shelves without enclosures in front, with great limitations in scenarios. Summary of the Invention

[0008] The purpose of the present invention is to provide a commodity display device that can be clamped at multiple angles. Based on a lifting drive mechanism, a telescopic drive mechanism, and a rotary drive mechanism, it can be applied to shelves with price tags and fences of a certain height, and can also be used for commodity shelves without enclosures in front, broadening the application range, and the movement latitude of multiple units is more dynamic, making it easier to attract the attention of passing customers.

[0031] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments. This embodiment is implemented on the premise of the technical solution of the present invention, and gives the detailed implementation mode and specific operation process, but the protection scope of the present invention is not limited to the following embodiments.

[0032] A commodity display device that can be clamped at multiple angles, such as Figure 1 and Figure 2 shown, includes a housing and a commodity fixing frame 6. There are strip holes on the housing. The device also includes a lifting drive mechanism, a telescopic drive mechanism, a rotary drive mechanism and a sheet metal bracket 10. The output end of the lifting drive mechanism is connected to the sheet metal bracket 10. The telescopic drive mechanism is installed on the sheet metal bracket 10, and the output end is connected to the rotary drive mechanism. The output end of the rotary drive mechanism is connected to the commodity fixing frame 6 through a spline 5 passing through the strip hole, and the driving direction of the lifting drive mechanism is consistent with the long axis direction of the strip hole.

[0033] Based on the lifting drive mechanism, the telescopic drive mechanism and the rotary drive mechanism, it can be applied to shelves with price tags and fences of a certain height, or to commodity shelves without enclosures in the front, which broadens the application range, and the movement latitude of multiple units is more dynamic and easier to attract the attention of passing customers.

[0034] In this embodiment, the lifting drive mechanism includes a first motor 4, a lead screw nut and a first slide rail slider assembly 13. The first motor 4 is fixed to the inner wall of the housing, and the output shaft is connected to the lead screw 3 of the lead screw nut and drives the lead screw 3 of the lead screw nut to rotate. The nut 11 of the lead screw nut is connected to the sheet metal bracket 10. The first slide rail slider assembly 13 is fixed to the inner wall of the housing, and the output end is connected to the sheet metal bracket 10. By rotating the first motor 4, the lead screw 3 is driven to rotate. Since the nut 11 is fixed, the nut 11 will lift along the lead screw 3, thereby driving the entire sheet metal bracket 10 to lift. Since the telescopic drive mechanism and the rotary drive mechanism are both fixed to the sheet metal bracket 10, the telescopic drive mechanism and the rotary drive mechanism together with the commodity fixing frame 6 will lift. Among them, two first slide rail slider assemblies 13 are provided, respectively located at both ends inside the housing, which can further improve the stability of the lifting process. The first motor 4 is a stepping motor, and the control accuracy is higher.

[0035] In this embodiment, the telescopic driving mechanism includes a second motor 21, a synchronous pulley 22, a driven pulley 17, a synchronous belt 19, a linear slide rail, a linear slider, and a slider fixing member 14. The second motor 21 is fixed to the sheet metal bracket 10, and its output shaft is connected to the synchronous pulley 22. The driven pulley 17 is installed on the sheet metal bracket 10 and is connected to and synchronized with the synchronous pulley 22 through the synchronous belt 19. The linear slide rail is installed on the sheet metal bracket 10, and the linear slider is arranged on the linear slide rail and slides along the linear slide rail. The synchronous teeth on the contact surface of the slider fixing member 14 are meshed and connected to the synchronous belt 19. The slider fixing member 14 is also connected to the rotational driving mechanism. Among them, the slider fixing member 14 and the second slide rail slider assembly 20 are fastened to the slider by screws. The slider fixing member 14 is connected to the tail of the spline 5 shaft through a self-lubricating bearing. The synchronous belt 19 is a closed-loop synchronous belt 19.

[0036] The rotational driving mechanism includes a third motor 9, a large bevel gear 15, a small bevel gear, a spline 5 shaft sleeve, and a ball bearing 7. Both the third motor 9 and the ball bearing 7 are installed in the sheet metal bracket 10. The output shaft of the third motor 9 is connected to the small bevel gear. The large bevel gear 15 is fitted with the small bevel gear and is connected to the spline 5 shaft sleeve to drive the spline 5 shaft sleeve to rotate. The spline 5 shaft sleeve is sleeved outside the spline 5 and slides along the spline 5. The spline 5 shaft sleeve is arranged in the ball bearing 7. One end of the spline 5 is connected to the commodity fixing bracket 6, and the other end is connected to the slider fixing member 14.

[0037] By the rotation of the second motor 21, the synchronous pulley 22 is driven to rotate. Based on the synchronous belt 19 and the driven pulley 17, the slider is driven to move, and finally the spline 5 is driven to move linearly. In the rotational driving mechanism, the bevel gear set composed of the large bevel gear 15 and the small bevel gear acts as a speed reducer. The rotation of the third motor 9 is transmitted to the spline 5 shaft sleeve through the bevel gear set, thereby driving the spline 5 to rotate.

[0038] In this embodiment, the limit of the telescopic driving part is realized by the telescopic zero position limit switch 12, and the rotation zero position switch 18 of the rotational driving part is realized.

[0039] In this embodiment, the ball bearing 7 is fixed by a ball bearing fixing seat 16, and the ball bearing fixing seat 16 is installed on the sheet metal bracket 10.

[0040] In this embodiment, the housing includes a bottom shell 1 and an upper cover, which can be conveniently disassembled.

[0041] In this embodiment, the device further includes an infrared sensor, an audio module, and a controller. The controller is configured to perform the following steps:

[0042] Receive the signal collected by the infrared sensor and judge whether someone is approaching based on the signal collected by the infrared sensor;

[0043] When it is determined that someone is approaching, the audio module is controlled to play pre-configured music, and the lifting drive mechanism, the telescopic drive mechanism and the rotating drive mechanism are controlled to move;

[0044] After the pre-configured music is played, the lifting drive mechanism, the telescopic drive mechanism and the rotating drive mechanism are controlled to reset.

[0045] Based on this, this embodiment can detect human bodies in the shelf corridor or other areas that need to be detected according to the external infrared sensor. When human activities are detected, the device will dynamically display goods and play corresponding advertising audio. The dynamic product display can be specifically described by an embodiment: after the sensor detects human activities, the embedded control board 2 inside the device controls the driving motors of the three axes of the motion drive component platform inside the device, and performs the lifting, extension, and rotating light display actions of the goods according to the preset parameters, and automatically brings the goods back to the zero position after the advertising sound ends. The embedded control board 2 is composed of a signal input interface, a motor drive, an audio playback chip, a programmable chip, and a power management chip. It can realize the driving of stepper motors and DC motors and read the pulse signal of the motor's own magnetic encoder, so as to perform tight closed-loop control of the action.

In addition to the basic product display function, this embodiment is also equipped with an NFC active code tag, which can remotely update the exhibition and promotion information, realize near-field communication and interact with the mobile phone by the customer's active mobile phone approaching, promote other products of the same category or similar category of the same merchant, or collect coupons, issue electronic membership cards, trace product information, etc.

[0047] In this embodiment, the energy storage power supply module can work for a certain period of time when there is no external power supply.

[0048] The product fixing frame 6 is composed of a fixing frame injection molding body, a sheet metal support frame and a lighting lamp. The fixing frame injection molding body is a plastic part, and its rear end is fitted with the equipment spline 5 axis through the spline 5 groove, and the fixing frame injection molding part and the spline 5 axis are locked by screws to prevent displacement in the telescopic direction. The fixed injection molding part is a semi-circular arc shape, and the side elevation of the product can be limited and fixed by sticking foam double-sided tape on both sides of the arc. The sheet metal support frame is fixed to the front end of the fixed injection molding part by screws. The sheet metal support frame is made of thin plate cutting and bending, and the sheet metal bottom support part is slightly tilted upward to prevent the product from falling due to the droop of the spline 5 axis caused by gravity during the telescopic process after the product is placed. The lighting panel is fixed on the sheet metal support frame at a certain distance from the product to achieve the best back lighting effect.
