DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0029] The terms "first" and "second" in this application are used to distinguish different objects, rather than to describe a specific order. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device that includes a series of steps, operations, components or modules is not limited to the listed steps, operations, components or modules, but may optionally include steps, operations, components or modules that are not listed, or may optionally include other steps, operations, components or modules that are inherent to these processes, methods, products or devices.

[0030] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0031] like Figures 1 to 7 As shown, a display device of an exemplary embodiment includes a base 1 and a column 2. The column 2 is rotatably connected to the base 1, that is, the column 2 is rotatably mounted on the base 1. The display device also includes at least one bracket 3 and a lighting assembly 4.

[0032] The bracket 3 is fixedly connected to the column 2. The lighting assembly 4 includes a telescopic rod 41, a connecting rod 42, a lamp holder 43 and a lighting lamp 44. The telescopic rod 41 is connected to the bracket 3, and one end of the telescopic rod 41 away from the bracket 3 is connected to the connecting rod 42 by a rotational manner, and one end of the connecting rod 42 away from the telescopic rod 41 is connected to the lamp holder 43 by a rotational manner. The lighting lamp 44 is arranged on the lamp holder 43.

[0033] More specifically, the bracket 3 is used to display the art design model for people to appreciate. In actual use, the user can adjust the length of the telescopic rod 41 according to the actual height or size of the art design model. For example, if the art design model is relatively tall, the user can extend the length of the telescopic rod 41, so that the connecting rod 42, the lamp holder 43 and the lighting lamp 44 will be away from the bracket 3, so that the distance between the lighting lamp 44 and the bracket 3 is increased. Due to the divergence of light, this configuration can fully illuminate the art design model, enhancing the display effect of the display device on the model.

[0034] Furthermore, the user can adjust the angle of the connecting rod 42 relative to the telescopic rod 41 and the angle of the lamp holder 43 relative to the connecting rod 42 to make a more precise adjustment to the lighting range of the lighting lamp 44. This humanized design helps to provide a better lighting effect and make the display effect of the art design model better.

[0035] The end of the telescopic rod 41 away from the bracket 3 is connected to the connecting rod 42 through the first rotating shaft 45, and the end of the connecting rod 42 away from the telescopic rod 41 is connected to the lamp holder 43 through the second rotating shaft 46. A damper is installed inside the first rotating shaft 45 and the second rotating shaft 46. The damper is a prior art, which is used to provide stable resistance in this scenario.

[0036] The design of the first rotating shaft 45 and the second rotating shaft 46 allows the connecting rod 42 and the lamp holder 43 to rotate within a certain range. When the user adjusts the position of the lighting lamp 44, the damper generates resistance, which can resist the tendency of drooping or rotating downward due to its own gravity, so that the connecting rod 42 and the lamp holder 43 can remain stable at any position set by the user.

[0037] The working principle of the damper is that when the connecting rod 42 and the lamp holder 43 try to rotate, resistance will be generated. This resistance is generated by friction or fluid resistance inside the damper, which can prevent the connecting rod 42 and the lamp holder 43 from rotating without external force. This design allows the user to manually adjust the position of the lighting lamp 44 and keep it stable after release, which improves the convenience and effect of the display device.

[0038] As an example, the bracket 3 includes a support plate 31 with an inner cavity, an outer sleeve 32, an inner sleeve 33, a drive assembly 34, a screw 35 and a connecting plate 36. The connecting plate 36 is connected to the column 2, and the two inner sleeves 33 and the two outer sleeves 32 are both arranged on the lower surface of the connecting plate 36.

[0039] There are two outer sleeves 32, which are fixedly mounted on the upper surface of the support plate 31, and a spacing for placing the art design model is formed between the two outer sleeves 32. The inner sleeve 33 is sleeved by the outer sleeve 32 and forms a sliding connection with the outer sleeve 32. Two screw rods 35 are respectively mounted inside the outer sleeve 32 and can rotate. Specifically, the screw rods 35 pass through the upper wall of the inner cavity of the bracket 3 and extend into the inner cavity, and the screw rods 35 are rotatably connected to the upper wall of the inner cavity. The driving assembly 34 is located in the inner cavity, and the lower ends of the two screw rods 35 are connected to the driving assembly 34. The screw rods 35 are threadedly connected to the inner wall of the inner sleeve 33.

[0040] Specifically, the drive assembly 34 is used to drive the two screws 35 to rotate. While the screws 35 are rotating, they can also extend or retract in the inner sleeve 33. The drive assembly 34 drives the screw 35 to rotate in the first direction, that is, the screw 35 extends from the inner sleeve 33, and the outer sleeve 32 and the support plate 31 both move downward relative to the inner sleeve 33. At this time, the inner sleeve 33 extends relative to the outer sleeve 32, and the support plate 31 moves downward relative to the connecting plate 36. Vice versa, when the drive assembly 34 drives the screw 35 to rotate in the second direction, the support plate 31 can move upward relative to the connecting plate 36. (The first direction and the second direction are opposite directions)

[0041] Please refer to Figure 7 If the height of the art design model is relatively high, the support plate 31 can be adjusted to be away from the connecting plate 36. In this case, the inner sleeve 33, the outer sleeve 32 and the connecting plate 36 are all located on the side of the art design model, forming an effective position restriction, preventing or greatly reducing the possibility of the art design model sliding off the side of the support plate 1.

[0042] As an example, in order to ensure a good sliding connection between the inner sleeve 33 and the outer sleeve 32 and prevent the inner sleeve 33 from rotating relative to the outer sleeve 32, the inner sleeve 33 and the outer sleeve 32 are designed to have a non-circular cross-section. For example, the cross-section may be square, rectangular, elliptical, polygonal or other non-circular, wherein the square cross-section is only one possible implementation form. Such a design can increase the stability between the inner and outer sleeves and prevent the inner sleeve from rotating during the sliding process.

[0043] As an example, the driving assembly 34 includes a driving shaft 341, two active bevel gears 342, two driven bevel gears 343 and a knob 344; the driving shaft 341 is rotatably installed in the inner cavity, and one end of the driving shaft 341 extends out of the inner cavity and is connected to the knob 344, the two active bevel gears 342 are installed on the driving shaft 341, and the two driven bevel gears 343 are installed on the lower end of the screw 35, and the active bevel gear 342 is meshed and connected with the driven bevel gear 343. In actual use, by rotating the knob 344, the driving shaft 341 is driven to rotate. The driving shaft 341 further drives the two active bevel gears 342 to rotate, and the active bevel gear 342 drives the two driven bevel gears 343 to rotate through the meshing connection. Finally, the rotation of the two driven bevel gears 343 drives the two screws 35 to rotate, thereby driving the screws 35. Furthermore, in the process of driving the two screw rods 35, the drive assembly 34 is driven by a drive shaft 341 as a driving force. With the single drive shaft 341 as a driving source, the drive assembly 34 has a unique design advantage. This design not only simplifies the structure of the device, improves its reliability and durability, but also ensures the synchronous driving of the two screw rods 35. Synchronous driving means that after receiving the power input of the drive shaft 341, the two screw rods 35 can move at almost the same rotation speed and rotation direction, thereby avoiding the misalignment or deflection that may occur during the sliding process of the inner and outer sleeves. This synchronous drive design makes it smoother and more accurate to adjust the height of the support plate 31 relative to the connecting plate 36, further improving the user experience and operating efficiency of the equipment.

[0044] As an example, in one embodiment, the support plate 31 is equipped with an annular seat 311. The annular seat 311 is designed to be sleeved on the column 2 and form a sliding connection therewith. In this way, the annular seat 311 provides an effective way to enhance the stability of the bracket 3 relative to the column 2. This design ensures that when the height or position of the bracket 3 is adjusted, its structure can be kept stable, preventing the bracket 3 from deflecting or shaking during use, thereby improving the overall stability and safety of the device.

[0045] As an example, a collar 361 is provided on the connecting plate 36, and the collar 361 is designed to be sleeved on the column 2 and to form a rotational connection with the column 2. In order to prevent the collar 361 from sliding off the column 2, the column 2 is designed to be provided with a limiting portion 21, and the limiting portion 21 is located between the upper surface and the lower surface of the collar 361. Due to the limiting effect of the limiting portion 21 on the collar 361, the collar 361 is safely restricted between the two limiting portions 21 during the rotation process. Specifically, the angle of the bracket 3 can be adjusted by adjusting its rotational position relative to the column 2. During the rotation process of the bracket 3 relative to the column 2, the collar 361 always keeps rotating between the two limiting portions 21, thereby ensuring the stability and safety of the entire device.

[0046] As an example, the telescopic rod 41 includes a housing 411, an extension rod 412 and a locking screw 413. In this design, the extension rod 412 is slidably mounted inside the housing 411, and the locking screw 413 passes through the side wall of the housing 411 and forms a threaded connection with the side wall of the housing 411. The specific operation process includes: first loosening the locking screw 413 so that it does not contact the extension rod 412, and then pulling the extension rod 412 out of the housing 411. By adjusting the extension length of the extension rod 412 in the housing 411, the length of the telescopic rod 41 can be adjusted. After determining the appropriate extension length of the extension rod 412, re-tighten the locking screw 413 so that it contacts the extension rod 412. At this time, the extension rod 412 will be fixed in place by the friction between it and the locking screw 413.

[0047] In the specific use process, the position of the lighting lamp 44 can be adjusted according to the scale of the art design model on the bracket 3. For example, if the art design model is large, the extension length of the extension rod 412 can be increased to increase the distance between the lighting lamp 44 and the bracket 3. Since the lighting light is divergent (this is because the light emitted by the light source generally diffuses in all directions during the propagation process to form a light cone, which is the so-called divergence of light. Different lighting lamps have different beam angles and divergences.), when the lighting lamp 44 is farther away from the bracket 3, the art design model can be more fully illuminated, thereby providing a better visual experience for the viewer and enhancing the display effect of the entire display device on the art design model.

[0048] As an example, the display device is further equipped with an infrared detector 5, which is fixed on the column 2 and electrically connected to the lighting lamp 44 through the controller. For example, the infrared detector 5 can be a widely used passive infrared sensor (PIR), which can sense changes in heat sources in the environment, especially infrared heat radiation emitted by moving human bodies.

[0049] The working principle is as follows: when a human body approaches the display device, the heat of the human body will change the surrounding environment of the infrared detector 5, causing the internal pyroelectric body to sense the heat change and generate an electrical signal. Then, this electrical signal will be sent to the internal signal processing circuit for analysis and processing.

[0050] The controller can be a microcontroller-based system, such as Arduino or Raspberry Pi, which is responsible for receiving and parsing the signal from the infrared detector 5. In this embodiment, the main task of the controller is to control the on and off of the lighting lamp 44 according to the signal of the infrared detector 5.

[0051] The specific control process is as follows: when someone approaches the display device, the infrared detector 5 senses the change in human body heat and generates a signal. After receiving the signal, the controller will send an on command to the lighting lamp 44 after internal program logic processing, so that the lighting lamp 44 lights up. On the contrary, when no one approaches, the infrared detector 5 will not generate any signal, so the controller will not send any command to the lighting lamp 44, so that the lighting lamp 44 remains in the off state. Such a design can not only realize automatic control, but also effectively save electricity and achieve environmental protection.

[0052] The communication between the controller and the illuminating lamp 44 may be realized through an interface called "GPIO" (General Purpose Input / Output). The "instruction" is usually an electrical signal generated by the program code running in the controller and sent to the illuminating lamp 44 through the GPIO interface.

[0053] When the controller receives the signal from the infrared detector 5, it generates an instruction in its internal program logic, for example, sending a "high" level signal (usually 5V or 3.3V) to the GPIO interface connected to the lighting lamp 44. At the hardware level, this "high" level signal will be received by the circuit of the lighting lamp 44 and interpreted as an "on" instruction, thereby driving the lighting lamp 44 to light up.

[0054] On the contrary, when the infrared detector 5 does not detect a human body, the controller will send a "low" level signal (usually 0V) to the GPIO interface connected to the lighting lamp 44. This "low" level signal will be interpreted by the circuit of the lighting lamp 44 as a "turn off" instruction, so that the lighting lamp 44 is turned off. Example

[0055] like Figure 1 and Figure 7As shown, the number of brackets 3 in this design is three, which is to meet different display needs. The angle of bracket 3 can be adjusted according to the actual scene and needs, so as to place and display different art design models. However, this does not mean that the number of brackets 3 must be limited to three. According to the actual use environment and needs, the number of brackets 3 can be adjusted accordingly. For example, if more art design models need to be displayed, or a large-scale display is required, the number of brackets 3 can be appropriately increased. On the contrary, if the display demand is small, or the display space is limited, the number of brackets 3 can also be reduced. In general, the specific number of brackets 3 should be flexibly configured according to actual needs to achieve the best display effect.

[0056] The exemplary embodiments of the present application may be combined with each other, and the exemplary embodiments obtained by the combination also fall within the scope of the present application.
