[0027] In order to make the purpose, technical scheme and advantages of the application more clear, the application is further described in detail below in combination with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the application, and are not used to limit the application.

[0028] Generally, the AR device for the intelligent business hall is mostly placed on the ground to realize AR interaction with the customer through the camera. The AR device has a high purchase cost and can only be guarded by the staff to ensure that it will not be damaged in the intelligent business hall. Meanwhile, when a user is experiencing, the AR device is not protected around, and if someone passes through the AR interaction area, it will seriously affect the AR interaction experience of the customer. In view of this, the application provides a protection device and an AR device system.

[0029] Referring to Figure 1 , Figure 1 A protection device structure schematic diagram provided by the embodiment of the application. As shown in Figure 1 , the protection device includes a base 10, a first protection assembly 20 and a second protection assembly 30. The base 10 is also used to install an AR device. The AR device refers to a device capable of providing AR technology, including but not limited to AR glasses, a display and the like. In the embodiment of the application, the AR device can be arranged on the base to realize AR interaction with the user through the camera.

[0030] Among them, the base 10 is provided with slide rails 110 on the opposite two sides, as shown in Figure 1 , the slide rails 110 are arranged on the opposite left and right two sides of the base 10. The first protection assembly 20 is arranged outside the slide rails 110 and close to the outer edge of the base 10. The first protection assembly 20 and the base 10 form a first protection chamber. The AR device is located in the first protection chamber. Among them, the first protection chamber refers to a three-dimensional space region formed by the first protection assembly 20 and the base 10.

[0031] The second protection assembly 30 is arranged on the slide rails 110. The second protection assembly 30 slides on the slide rails 110 relative to the first protection assembly 20 to switch between a folded state and an unfolded state. Among them, the folded state refers to that the second protection assembly 30 slides on the slide rails 110 towards the first protection assembly 20 to slide to a first limiting end. Among them, the first limiting end can be an end of the first protection assembly 30 connected with one side of the base 10 without the slide rails 110. As shown in Figure 1 , the first limiting end includes an end point X1. The unfolded state refers to that the second protection assembly 30 slides on the slide rails 110 away from the first protection assembly 20 to slide to a second limiting end. Among them, the second limiting end can be the other end of the projection of the first protection assembly 30 on the base 10 relative to the first limiting end. As shown in Figure 1 , the second limiting end includes an end point X2.

[0032] The second protection assembly 20 is partially or fully overlapped with the first protection assembly 20 during the sliding of the second protection assembly 20 on the slide rail 110. When the second protection assembly 30 is in the unfolded state, the second protection assembly 30, the first protection assembly 20, and the base 10 form a second protection chamber. The second protection chamber refers to a three-dimensional space region formed by the second protection assembly 30, the first protection assembly 20, and the base 10 when the second protection assembly 30 is in the unfolded state. The accommodation space of the second protection chamber is larger than that of the first protection chamber. Figure 1 The protection device shown in the figure is in the unfolded state.

[0033] The protection device includes a base provided with slide rails on opposite sides, and the base is used to install an AR device. The protection device also includes a first protection assembly arranged outside the slide rail and close to the outer edge of the base. The first protection assembly and the base form a first protection chamber to protect the AR device inside the first protection chamber without special care for the AR device, thereby reducing the cost and workload of the staff and improving the work efficiency of the staff. The protection device also includes a second protection assembly arranged on the slide rail. The second protection assembly slides on the slide rail relative to the first protection assembly to switch between a folded state and an unfolded state. When the second protection assembly is in the unfolded state, the second protection assembly, the first protection assembly, and the base form a second protection chamber. The accommodation space of the second protection chamber is larger than that of the first protection chamber to accommodate more users. During the interaction of the users with the AR device in the second protection chamber, the second protection chamber isolates the AR interaction area from the external environment, avoids random passing through the AR interaction area by others, eliminates external interference, and improves the AR interaction experience of the users.

[0034] In one embodiment, when the second protection assembly 30 is in the folded state, the second protection assembly 30 is slidably embedded into the first protection assembly 20. That is, the first protection assembly 20 can completely contain the second protection assembly 30. For Figure 1 The protection device shown in the figure is in the folded state. Figure 2 In actual applications, when there is no user using the AR device or the AR device is stopped, the second protection assembly 30 is slidably embedded into the first protection assembly 20 through the slide rail 110 to be in the folded state. When there is a user using the AR device, the second protection assembly 30 embedded into the first protection assembly 20 is pulled out through the slide rail 110 to be in the unfolded state. The state of the second protection assembly 30 can be set according to actual application requirements.

[0035] The second protection assembly is switched between the folded state and the unfolded state by sliding on the slide rail of the base to meet the needs of different scenarios. When the AR device is not used or stops being used, the second protection assembly can be set to the folded state to expand the remaining space outside the second protection chamber, improve the space utilization, and enable open public areas such as business halls and shopping malls to accommodate more customers. When the AR device is used, the second protection assembly can be set to the unfolded state to expand the space of the second protection chamber, increase the AR interaction area, and improve the AR interaction experience.

[0036] In one of the embodiments, the second protection assembly 30 includes a plurality of sub-protection components that are connected in linkage, each of which is provided with a roller and the roller is arranged on the slide rail 110. The sub-protection components are sub-assemblies for composing the second protection assembly, and each of the sub-protection components can slide on the slide rail 110 in linkage with each other. The number of the sub-protection components can be set according to the actual application scenario, which is not limited herein.

[0037] For better understanding of the specific structure of the second protection assembly 30 in the above embodiments, please refer to Figure 3 , Figure 3 Another protection device structure schematic diagram provided by the embodiments of the present application is shown in Figure 3 In the scenario shown, the second protection assembly 30 includes two sub-protection components 310 and 320 that are connected in linkage. Each of the sub-protection components 310 and 320 is provided with a roller, and each of the rollers is arranged on the slide rail 110.

[0038] It should be noted that the sub-protection component 310 can slide on the slide rail 110 relative to the sub-protection component 320 to switch between the folded state and the unfolded state. When the sub-protection component 310 is in the folded state, the sub-protection component 310 can be slidably embedded into the sub-protection component 320. When the sub-protection component 310 is in the unfolded state, the sub-protection component 310, the sub-protection component 320, the first protection assembly 20, and the base 10 form a second protection chamber. The sub-protection component 310 and the sub-protection component 320 can slide on the slide rail 110 relative to the first protection assembly 20 to switch between the folded state and the unfolded state. When in the folded state, the sub-protection component 310 and the sub-protection component 320 are both slidably embedded into the first protection assembly 20. When in the unfolded state, the sub-protection component 310 can be slidably embedded into the sub-protection component 320, and the sub-protection component 310, the sub-protection component 320, the first protection assembly 20, and the base 10 form a second protection chamber Y1, or the sub-protection component 310, the sub-protection component 320, the first protection assembly 20, and the base 10 form a second protection chamber Y2, and the accommodation space of the second protection chamber Y2 is larger than that of the second protection chamber Y1.

[0039] The number and type of the rollers can be set according to actual conditions, and no limitation is made herein. In order to better understand the structural relationship between the second protection assembly 30, the rollers and the slide rail 110 in the embodiment, the corresponding area N of the sub-protection component 310 shown in Figure 3 will be further described. Figure 4 As shown in Figure 4 , the sub-protection component 310 is provided with a plurality of rollers 330, the rollers 330 are arranged on the slide rail 110 of the base 10, and the sub-protection component 310 can slide on the slide rail 110 through the rollers 330.

[0040] The above-mentioned second protection assembly is composed of a plurality of sub-protection components arranged in linkage, which expands the accommodation space of the second protection room, increases the AR interaction area, and thus improves the AR interaction experience. In addition, by arranging the rollers on each sub-protection component of the second protection assembly, and arranging the rollers on the slide rail of the base, the friction between the second protection assembly and the slide rail is reduced, so that the second protection assembly slides more smoothly and quickly on the slide rail, and the state of the second protection assembly is switched more conveniently.

[0041] In one of the embodiments, please continue to refer to Figure 3 , among the plurality of sub-protection components arranged in linkage, the sub-protection component arranged at the outermost side further comprises a protection fence 340 and a rolling shutter door 350 connected with the protection fence 340, and the rolling shutter door 350 can be arranged in sliding relative to the protection fence 340. Optionally, the rolling shutter door 350 comprises a smart chip, and in the application process, the smart chip of the rolling shutter door 350 can be connected with a smart device to control the rolling shutter door 350 to slide, automatically open or close the second protection room.

[0042] As shown in Figure 3 , the protection device comprising the sub-protection component 310 and the sub-protection component 320 is taken as an example, the sub-protection component arranged at the outermost side is the sub-protection component 310, and the sub-protection component 310 further comprises the protection fence 340 and the rolling shutter door 350, wherein the protection fence 340 is connected with the rolling shutter door 350, and the rolling shutter door 350 can be arranged in sliding relative to the protection fence 340. That is, the rolling shutter door 350 slides relative to the protection fence 340 to close or open the second protection room. For example, during the use of the AR device for AR interaction or the stop of business, the rolling shutter door 350 can be slid to close the second protection room, so as to completely isolate the second protection room from the outside world, avoiding the interference of the outside world during the AR interaction and the damage of the protection device and the AR device caused by the entry of others into the second protection room during the stop of business. In the case that the business is in operation but no one uses the AR device for AR interaction, the rolling shutter door 350 can be slid to open the second protection room, so as to enable the customers to enter the second protection room to experience the AR technology.

[0043] The protective fence and the rolling shutter door are arranged on the outermost sub-protection component of the second protection assembly, the rolling shutter door is slid according to the specific application scene to manage the opening and closing of the second protection room, the switching between the communication and the isolation between the second protection room and the external environment is realized, and the AR interaction experience is further improved.

[0044] In one of the embodiments, the rolling shutter door 350 includes a door plate, a support, a guide rail, a driving module and a locking module; the door plate is connected to the guide rail through the support, the guide rail is connected to the driving module, and the driving module is used to drive the guide rail to drive the door plate to slide; when the door plate reaches the preset position of the protective fence 340, the locking module locks the door plate on the base 10, so that the second protection room becomes a closed protection room.

[0045] The rolling shutter door includes a door plate, a support, a guide rail, a driving module and a locking module, the management of the opening and closing of the second protection room is realized, and the AR interaction experience is further improved.

[0046] In one of the embodiments, please continue to refer to Figure 3 The protection device further includes a height acquisition module and a data transmission module 40. The height acquisition module is used to acquire the height information of the user to be detected using the AR device. Optionally, the height acquisition module can be a sensor for measuring height, such as an ultrasonic ranging sensor. The data transmission module 40 is arranged on the base 10 and is connected to the height acquisition module and the AR device respectively, and is used to transmit the received height information to the AR device, so as to instruct the AR device to adjust the angle of the image acquisition module of the AR device according to the received height information. The image acquisition module is a device with a shooting function, for example, a video camera, a camera, etc. Optionally, the data transmission module 40 can be a data transmission board. The height acquisition module is arranged on the data transmission module 40. The number, type and specific position of the height acquisition module and the data transmission module 40 can be set according to the actual application scene, and are not limited herein.

[0047] For example, the protection device shown in Figure 3 The height information of the user to be detected is acquired by the height acquisition module and is sent to the data transmission module 40. The data transmission module 40 transmits the received height information to the AR device. The AR device adjusts the angle of the image acquisition module for shooting the user to be detected according to the received height information.

[0048] The height information of the user to be detected is collected by the height collection module, and the height information is transmitted to the AR device by the data transmission module, so that the AR device can adjust the angle of the image height collection module according to the height information, so that the AR device is suitable for users with different heights, and the bad interactive experience of users due to the fixed AR device and the height difference between users is avoided, and the AR interactive experience of users is improved.

[0049] In one of the embodiments, please refer to Figure 5 and Figure 6 , Figure 5 A base structure schematic diagram provided by an embodiment of the application, Figure 6 A data transmission module structure schematic diagram provided by an embodiment of the application, and Figure 6 is an enlarged schematic diagram of the area A in Figure 5 The data transmission module 40 is fixedly connected to the mounting area of the base 10 by the bolt 410, and the data transmission module 40 and the mounting area of the base 10 are both provided with holes corresponding to the bolt 410. The number of bolts 410 and holes can be set according to the actual scene, and is not limited herein. The projection of the first protection assembly 20 towards the base 10 does not overlap the mounting area, that is, the mounting area is not in the first protection chamber. As shown in Figure 5 and Figure 6 , the opposite two sides of the base 10 are provided with slide rails 110, the AR device 50 is installed on the base 10, and the data transmission module 40 is fixedly connected to the base 10 by four bolts 410.

[0050] The data transmission module is fixedly connected to the base by the bolt, which consolidates the connection between the data transmission module and the base. Since the data transmission module is arranged on the base and is stepped on by the user for a long time, it is easy to be damaged and cause inaccurate data transmission. Therefore, when the data transmission module is damaged and cannot be used, the bolt can be unscrewed to replace a new data transmission module in time, ensuring the data transmission in the AR interactive process, thereby ensuring a high AR interactive experience.

[0051] In one of the embodiments, please continue to refer to Figure 3The protection device further comprises a Bluetooth cooling fan 60 arranged on the top of the first protection assembly 20 and used for cooling the AR device 50. Optionally, the Bluetooth cooling fan 60 comprises a Bluetooth module, a driving module, a Hall induction assembly and a fan. The Bluetooth module is used for receiving a Bluetooth signal. The driving module is connected with the Bluetooth module and the Hall induction assembly respectively and used for sending a control signal to the Hall induction assembly according to the received Bluetooth signal. The Hall induction assembly is connected with the fan and used for controlling the fan to rotate or stop rotating according to the received control signal. In other words, the Hall induction assembly is used as a synchronous detection device to control a group of circuits, switch the winding power-on sequence, generate a rotating magnetic field and realize a new type of fan with electromechanical integration of electronic commutation. In actual application, the Bluetooth smart cooling fan 60 can be turned on or off at any time through Bluetooth connection, thereby cooling the AR device 50.

[0052] The Bluetooth cooling fan arranged on the top of the first protection assembly can control the fan to be turned on or off through Bluetooth technology, so that the heat generated by the AR device can be quickly discharged when the temperature in the first protection chamber or the second protection chamber is too high, and the AR interactive experience of the user is not affected by the overheating of the AR device.

[0053] In one of the embodiments, please continue to refer to Figure 5 The protection device further comprises a signal emission module 70 arranged on the base 10 and connected with the AR device 50 and used for emitting a network signal for the AR device 50 to use the network signal for AR interaction. The signal emission module 70 is a device capable of providing a signal, such as a WIFI signal emitter, a 4G / 5G emitter and the like. Optionally, the signal emission module 70 is arranged at the bottom of the AR device 50. As shown in Figure 5 The signal emission module 70 is a WIFI signal emitter 70 arranged at the bottom of the AR device 50 and located on the base 10.

[0054] In public places such as business halls and shopping malls, the network signal is not smooth due to a large number of people gathering, and the AR device needs to use the network signal, so that the AR interactive experience of the user is seriously affected when the network signal is not smooth. Based on this, the protection device has the signal emission module for emitting the network signal, so that the AR device can use the network signal to interact with the user, and the network signal can be smooth when a large number of users gather, thereby ensuring the AR interactive experience of the user.

[0055] The application further provides an AR device system comprising the protection device according to any one of the embodiments and the AR device arranged in the first protection chamber.

[0056] The AR device system includes a protective device and an AR device arranged in a first protective chamber. The protective device includes a base provided with slide rails on opposite sides of the base, and the base is used to mount the AR device. The protective device further includes a first protective assembly arranged outside the slide rails and close to the outer edges of the base. The first protective assembly and the base enclose the first protective chamber to protect the AR device in the first protective chamber. The AR device does not need to be specially cared for, which reduces the investment cost and the workload of the staff, and improves the work efficiency of the staff. The protective device further includes a second protective assembly arranged on the slide rails. The second protective assembly slides on the slide rails relative to the first protective assembly to switch between a folded state and an unfolded state. When the second protective assembly is in the unfolded state, the second protective assembly, the first protective assembly, and the base enclose the second protective chamber. The accommodation space of the second protective chamber is larger than that of the first protective chamber to accommodate more users. In the process of using the AR device for interaction in the second protective chamber, the second protective chamber isolates the AR interaction area from the external environment, avoids random walking of others from the AR interaction area, eliminates external interference, and improves the AR interaction experience of the users.

[0057] In order to better understand the protective device and the AR device system provided by the above embodiments, the protective device shown in Figures 3 to 6 will be taken as an example to illustrate the application scene of the smart business hall.

[0058] In actual application, it is necessary to ensure that all parts of the protective device are intact in advance. After inspection, the protective device is placed in a fixed position in the smart business hall. The staff of the smart business hall needs to first slide the second protective assembly 30, i.e. the sub-protective components 310 and 320, on the slide rails 110 through the rollers 330, so that the sub-protective components 310 and 320 are pulled out of the first protective assembly 20 to be in the unfolded state. At this time, the base 10, the first protective assembly 20, and the sub-protective components 310 and 320 enclose the second protective chamber to serve as an AR interaction experience space. When the user uses the AR device 50 for AR interaction experience in the space, the AR interaction area is isolated from the external environment, so that others cannot walk through the AR interaction experience space, thereby improving the AR interaction experience of the user.

[0059] In the AR interaction process, the AR device 50 is powered on to work, the user can stand on the data transmission plate 40 arranged on the base 10 to interact with the AR device 50, the sensor arranged below the data transmission plate 40 collects the height information of the user, and transmits the height information to the AR device 50 through the data transmission plate 40, then the AR device 50 adjusts the angle of the camera after data processing of the height information, so as to adapt to the height of the user to provide the best AR interaction experience. When the AR device 50 is not in use or no customer uses it, the staff of the intelligent business hall can directly connect and control the sliding of the door plate of the rolling shutter door 350 with the mobile phone, when the door plate reaches the preset position of the protective fence 340, the locking module locks the door plate on the base 10, so that the second protective chamber becomes a closed protective chamber, so that the AR device 50 can be locked in the second protective chamber to avoid other people contacting or damaging the core components of the AR device 50 and the protective device.

[0060] When the data transmission plate 40 is damaged due to long-term trampling by customers, causing inaccurate data transmission, the bolt 410 can be unscrewed to replace the new data transmission plate 40 in time. Because the intelligent business hall needs to receive many users every day, a large number of people gathering will cause the network signal to be not smooth, which will seriously affect the AR interaction experience of the user, so when the network signal is not smooth, the WIFI transmitter 70 is powered on to emit WIFI signal, the AR device 50 can connect the WIFI signal by password, so that the user can normally use the AR device 50 for AR interaction, so that the network signal can be smooth when a large number of customers gather. In addition, the AR device 50 will emit a large amount of heat during operation, which can easily cause the device to overheat and be damaged if not cooled in time, and also affect the AR interaction experience of the user, so when the AR device 50 operates for a long time, the Bluetooth cooling fan 60 is powered on first, then the Bluetooth cooling fan 60 is turned on and off at any time through Bluetooth connection, so that the heat in the second protective chamber is quickly discharged, thereby avoiding the influence of device overheating on the AR interaction experience of the user.

[0061] The technical features of the above-described embodiments can be combined in any manner. To make the description concise, all possible combinations of the technical features in the above-described embodiments are not described, but as long as the combinations of the technical features do not exist contradictory, they should be considered as the scope of the present disclosure.

[0062] The above-described embodiments only express several implementation manners of the present application, and the description is more specific and detailed, but it should not be understood as a limitation on the scope of the patent. It should be pointed out that for ordinary skilled in the art, without departing from the concept of the present application, some modifications and improvements can be made, which are all within the protection scope of the present application. Therefore, the protection scope of the patent of the present application should be subject to the appended claims.
