[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back...) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0027] In the present invention, unless otherwise clearly specified and limited, the terms "connection", "fixation", etc. should be understood in a broad sense. For example, "fixation" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0028] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the utility model, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the meaning of "and / or" appearing in the full text includes three parallel schemes. Taking "A and / or B" as an example, it includes scheme A, or scheme B, or a scheme that satisfies both A and B. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the utility model.

[0029] In the prior art, Chinese patent CN211021886U provides an exhibition stand with a warning function, which uses an infrared curtain detector to monitor whether someone touches the painting. If someone touches it, a warning can be issued through sound; however, in this solution, there may be a situation where someone triggers the sensor but does not actually touch or damage the painting, that is, the entire system has a misjudgment. In this case, the alarm will continue to work until it is manually turned off or set to a timed shutdown, which will bring a bad viewing experience to the viewer during the alarm time. In addition, the misjudgment alarm will also increase unnecessary workload for the staff. Based on this patent, if the monitoring position of the infrared curtain detector is set very close to the painting in order to prevent misjudgment, it will not be possible to warn tourists in time and remind them to stay away from the painting, because when the infrared curtain detector is triggered, the tourist has already touched the painting and it will not protect the painting.

[0030] To make up for the deficiencies of the prior art, an embodiment of the present application provides an anti-touch display stand, including a display stand frame 1, a vibration sensor 2, an infrared curtain detector 3, a first warning device 4 and a second warning device 5;

[0031] The exhibition frame 1 is used to place exhibits, the vibration sensor 2 is arranged on the exhibition frame 1, the vibration sensor 2 is electrically connected to the first warning device 4, and the first warning device is arranged in the control room of the exhibition hall;

[0032] The infrared curtain detector 3 is disposed on the display frame 1 . The infrared curtain detector 3 is electrically connected to the second warning device 5 . The second warning device 5 is disposed on at least one side of the display frame 1 .

[0033] The touch-proof display stand designed in this application divides touch monitoring into two levels, and has two different corresponding warning methods. Specifically, the infrared curtain detector 3 is used to monitor whether there is an object approaching the exhibit. When an object triggers the infrared curtain detector 3 (without touching the exhibit), the second warning device 5 responds and works to warn the person in front of the exhibit, reminding the viewer not to touch or stay away from the exhibit; and the vibration sensor 2 can monitor any vibration of the exhibit. When someone touches the exhibit, the slight vibration generated by the exhibit is sensed by the vibration sensor 2, and the first warning device 4 is controlled to respond to remind the staff that the exhibit has been touched.

[0034] By combining two monitoring means and two alarm devices, the anti-touch display stand of the present application will not cause false alarms and can warn viewers in time.

[0035] The vibration sensor 2 is also called a vibrometer or a vibrometer. Its function is to accurately receive the mechanical vibration quantity (displacement, velocity or acceleration) of the measured object, and convert this mechanical quantity into an electrical signal (current or voltage) to output or display it, thereby realizing the conversion of mechanical energy into electrical energy.

[0036] As an optional implementation of the present application, in order to enhance the warning effect of the exhibition stand, the exhibition stand also includes a light source for illuminating the exhibits, and the light source is electrically connected to the infrared curtain detector 3. The light source is in a constant on state. When the infrared curtain detector 3 is triggered, a signal is sent to control the light source to go out, and at the same time, the second warning device 5 on the side will be turned on. Specifically, the second warning device 5 can be a warning light surrounding the exhibition stand frame 1, which emits red light when it is on. The light irradiating the exhibits goes out and the warning light turns on, which can form a visual effect with strong contrast and enhance the warning effect; at the same time, since the light source irradiating the exhibits goes out, it will seriously affect the viewing effect, thereby promoting viewers to supervise each other and actively stop others from touching. When the infrared curtain detector 3 does not detect any touching behavior, the light source turns on again, which does not affect the display effect. That is, the second warning device 5 will only work when an object enters the detection range of the infrared curtain detector 3, which basically does not affect the viewing experience.

[0037] The detection range of the infrared curtain detector 3 covers the surface of the exhibits and is preferably 5-10 cm away from the exhibits, that is, when an object is 5-10 cm away from the exhibits, the infrared curtain detector 3 will be triggered, and then the second warning device 5 will immediately remind the viewer to stay away from the exhibits.

[0038] As an optional embodiment of the present application, the first warning device 4 is an audible and visual alarm arranged at the far end of the exhibition stand. The first warning device 4 will respond only when the exhibit is actually touched, and is used to notify the staff of the exhibition hall that the exhibit has been touched and to respond in time.

[0039] As an optional implementation of the present application, the second warning device 5 is a warning light and / or a display. Since some exhibitions have high requirements for the aesthetics and artistry of the exhibition, setting a conspicuous "Do Not Touch" sign directly next to the exhibits will affect the display effect. Therefore, this embodiment sets a display screen next to the exhibits. The display screen is normally black and can be hidden next to the exhibits with the help of lighting design, which does not affect the aesthetics of the display. The display screen will only light up when an object is too close to the exhibits to give a prompt, such as displaying the words "Do Not Touch". The display screen can be an LED display screen.

[0040] As an optional implementation of the present application, the exhibition frame 1 is a wall-mounted exhibition frame 1, a flexible substrate 101 is provided on the exhibition frame 1, the exhibit is attached to the flexible substrate 101, and the vibration sensor 2 is provided on the flexible substrate 101. The wall-mounted exhibition frame 1 of this embodiment is installed on the wall and is suitable for displaying paintings. The flexible substrate 101 can ensure that the vibration generated by the touch is detected by the sensor to the greatest extent.

[0041] As an optional implementation of the present application, the vibration sensor 2 is a patch type vibration sensor 2. The patch type vibration sensor 2 is small in size and easy to install, and can be well integrated into exhibition frames 1 of different structures and sizes.

[0042] As an optional embodiment of the present application, the display frame 1 is a flat display frame 1, and the flat display frame 1 includes a balancing base 6, and the exhibit is arranged on the balancing base 6; an elastic member 7 for supporting the balancing base 6 and keeping the balancing base 6 balanced is arranged below the balancing base 6. ， In order to ensure the balance of the balancing base 6, the elastic member 7 should be arranged around the center of mass of the balancing base 6, that is, the center of the support point of the elastic member 7 and the center of mass of the balancing base 6 are coincident in the horizontal projection, so that the balancing base 6 can maintain a balanced state (horizontal state) when not affected by external forces; and because the balancing base 6 is supported by the elastic member 7, when the exhibit or the balancing base 6 is subjected to external forces, the elastic member 7 will be deformed, that is, the balancing base 6 will shake (vibrate), and the vibration sensor 2 is arranged on the balancing base 6, and at this time the vibration sensor 2 can monitor the vibration signal, thereby realizing touch monitoring of the exhibit.

[0043] The flat display frame 1 of this embodiment is placed on a horizontal surface and is suitable for displaying various items that need to be placed horizontally.

[0044] As an optional embodiment of the present application, in order to ensure that the balancing base 6 does not tilt significantly, an anti-tilt support 8 is provided under the balancing base 6. The anti-tilt support 8 is used to support the balancing base 6 when the balancing base 6 tilts at a small angle to prevent it from further tilting.

[0045] As an example, the balancing base 6 is rectangular, and the anti-tilt support 8 can be set as support rods distributed at the four corners of the balancing base 6. The distance between the top of the anti-tilt support 8 and the balancing base 6 is designed according to the size of the balancing base 6. The principle is to ensure that the maximum tilt angle of the balancing base 6 does not exceed 5°.

[0046] In order to ensure the aesthetics of the display, the upper surface of the balancing base 6 is flush with the plane of the display platform, and the elastic member 7 and the anti-tilt support member 8 are concealedly arranged inside the display platform.

[0047] As an example, the elastic member 7 is a spring, and three springs are arranged on the balancing base 6 for support so that the balancing base 6 can maintain balance without being affected by external forces. At this time, the connecting line of the three springs forms an equilateral triangle, and the center of the equilateral triangle coincides with the horizontal projection of the center of mass of the balancing base.

[0048] As an optional implementation of the present application, in order to further ensure the safety of the exhibits, the exhibits are placed slightly downward on the balancing base 6, which provides limited protection for the exhibits and ensures that the exhibits will not slide or roll when the balancing base 6 is slightly tilted.

[0049] As an optional embodiment of the present application, the vibration sensor 2 includes a vibration judgment unit, which is used to judge the size of the acquired vibration signal and send an alarm instruction to the first warning device 4 according to the size of the vibration signal. The function of the vibration judgment unit is to judge the vibration size, because other factors (such as sound) at the exhibition site may also trigger the vibration detector. Such slight vibration signals need to be excluded. Therefore, the vibration judgment unit can determine whether an alarm is needed by judging the size of the signal data. When the vibration signal is greater than the preset threshold, a warning instruction is issued. The specific threshold size can be determined by experiment.

[0050] Those skilled in the art will appreciate that the embodiments described herein are intended to help readers understand the principles of the present invention, and should be understood that the protection scope of the present invention is not limited to such specific statements and embodiments. Those skilled in the art can make various other specific variations and combinations based on the technical inspirations disclosed in the present invention without departing from the essence of the present invention, and these variations and combinations are still within the protection scope of the present invention.
