[0002] In the relevant technical field, smart interactive tablets have functions such as writing, annotation, synchronous interaction, multimedia, and remote video conferencing, and are often used in conference rooms, media studios, etc. In order to facilitate the signal interaction of smart interactive tablets, slot antennas are often used. Considering that the use scenario of smart interactive tablets is in front of the display area and the frame is made of metal, it is often necessary to set a slot on the front of the smart interactive tablet so that the slot antenna can radiate or receive signals through the slot. However, the slot on the front will affect the integrity of the front of the smart interactive tablet. Summary of the invention

[0003] The embodiment of the present application provides a smart interactive tablet, which aims to enable the slot antenna to utilize the black edge area of ​​the display screen to radiate signals, thereby eliminating the need to open a hole on the front of the display screen, and allowing the front of the smart interactive tablet to remain flat.

[0004] An embodiment of the present application provides an intelligent interactive tablet, including a display screen, a back panel and an antenna assembly, wherein the display screen has a display area and a black border area surrounding the display area; the back panel is connected to the back of the display screen, and the back panel has a gap; the antenna assembly is connected to a side of the back panel away from the display screen, and is arranged corresponding to the gap; wherein the display screen has a light emitting direction, and the projection of the antenna assembly on the display screen along the light emitting direction is located in the black border area, so that the antenna assembly can send and receive signals through the gap and the black border area.

[0005] Based on the above embodiment, along the light emitting direction, the projection of the antenna assembly on the display screen is located in the black border area. Since there is no metal wire in the black border area of ​​the display screen, the antenna assembly can transmit signals toward the front and back of the display screen through the black border area. There is no need to open a hole on the front of the display screen, so the front of the smart interactive tablet can remain flat.

[0006] In some of the embodiments, the antenna assembly includes a circuit board, which is connected to the side of the back panel facing away from the display screen, and the circuit board has a slot antenna, which is arranged corresponding to the slot; wherein, along the light emitting direction, the projection of the slot antenna on the back panel is located in the slot.

[0007] Based on the above embodiments, the slot antenna can transmit and receive signals along the light emitting direction of the display screen through the slot and the black border area, thereby improving the accuracy of transmitting and receiving signals; the projection of the slot antenna on the back panel is located within the slot, so that the signal radiated by the slot antenna can be radiated completely through the slot, thereby reducing the influence of the back panel on the signal, and improving the accuracy of transmitting and receiving signals by the slot antenna.

[0008] In some of the embodiments, the antenna assembly further includes a radio frequency chip, which is disposed on the circuit board and connected to the slot antenna.

[0009] Based on the above embodiment, the RF chip is arranged on the circuit board so that the RF chip can be used to feed the slot antenna, thereby facilitating the slot antenna to transmit and receive signals. The distance between the RF chip and the slot antenna can also be made closer, thereby avoiding the loss and interference caused by the longer connecting wires, and improving the signal transmission and reception efficiency of the slot antenna.

[0010] In some embodiments, the antenna assembly further includes a metal shielding cover, which is disposed on a side of the circuit board facing away from the back plate, and a receiving cavity is surrounded by the metal shielding cover and the circuit board, and the slot antenna is located in the receiving cavity.

[0011] Based on the above embodiments, the use of a metal shield can reduce the interference of other signals on the slot antenna, thereby improving the accuracy of the signal received by the slot antenna. Furthermore, since the metal shield is provided on the side of the circuit board away from the back plate, a resonant cavity can be formed in the mass cavity to enhance the strength of the signal sent by the slot antenna.

[0012] In some of the embodiments, a plurality of slot antennas are arranged at intervals, and along the light emitting direction, projections of the plurality of slot antennas on the back panel are all located in the same slot.

[0013] Based on the above embodiments, a plurality of slot antennas arranged at intervals may be used to improve the signal receiving and sending capability of the antenna assembly, thereby improving the stability of the signal receiving and sending.

[0015] Based on the above embodiments, multiple slot antennas can be used to transmit and receive multiple signals, so as to increase the frequency band and application functions radiated by the slot antennas and improve the signal transmission and reception efficiency of the antenna assembly.

[0016] In some embodiments, along the width direction of the smart interactive tablet, the slot has a first width, the slot antenna has a second width, the first width is greater than or equal to 1 mm and less than or equal to 6 mm, the second width is greater than or equal to 1 mm and less than or equal to 6 mm, and the first width is greater than or equal to the second width.

[0017] Based on the above embodiment, the corresponding second width may be adapted according to the wavelength of the signal radiated by the slot antenna, thereby meeting the radiation requirement of the slot antenna.

[0018] In some embodiments, the first width is 5 mm and the second width is 2.5 mm.

[0019] In some of the embodiments, the antenna assembly further includes a board-mounted antenna and a steel sheet antenna. Both the board-mounted antenna and the steel sheet antenna are disposed on the circuit board and spaced apart from the slot antenna.

[0020] Based on the above embodiments, the use of the onboard antenna and the steel sheet antenna can enable the antenna assembly to have more signal receiving and sending functions to meet different signal receiving and sending requirements.

[0021] In some of the embodiments, the smart interactive tablet further includes a decorative piece, which is disposed on a side of the back panel facing away from the display screen, and a receiving cavity is formed between the decorative piece and the back panel, and the antenna assembly is disposed in the receiving cavity.

[0022] Based on the above embodiments, the antenna assembly can be protected by using a decorative piece to reduce the probability of damage to the antenna assembly, thereby allowing the antenna assembly to have a longer service life.

[0023] Based on the smart interactive tablet of the present application, along the light emitting direction, the projection of the antenna assembly on the display screen is located in the black border area. Since there is no metal wire in the black border area of ​​the display screen, the antenna assembly can transmit signals toward the front and back of the display screen through the black border area. There is no need to open a hole on the front of the display screen, so the front of the smart interactive tablet can remain flat. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0031] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0032] Please refer to Figure 1 and Figure 2 An embodiment of the present application provides a smart interactive tablet 1, including a display screen 11, a frame 12, a back panel 13 and an antenna assembly 14.

[0033] The display screen 11 is used to display images and receive user touch commands. The specific display screen 11 can be at least one of a liquid crystal display (LCD), a light emitting diode display (LED), an organic light-emitting semiconductor display (OLED), a sub-millimeter light emitting diode display (Mini Light Emitting Diode, Mini LED) and a micro light emitting diode display (Micro Light Emitting Diode, Micro LED). In the embodiment of the present application, the specific form of the display screen 11 is not limited. The display screen 11 has a display area 11A for display and a black border area 11B surrounding the display area 11A. Due to process limitations, the metal wiring of the display screen 11 will be blank at 4mm-5mm from the edge to form a black border area 11B. The black border area 11B has little effect on electromagnetic waves because there is no metal wiring.

[0034] The frame 12 is arranged around the display screen 11 to support the display screen 11 and protect the display screen 11, thereby extending the service life of the display screen 11. Exemplarily, the material of the frame 12 can be metal, plastic or wood. In the embodiment of the present application, the material of the frame 12 is not limited.

[0035] The back plate 13 is connected to the frame 12 and is disposed on the back of the display screen 11 to support the display screen 11. The back plate 13 may be made of metal to increase the strength of the connection structure between the back plate 13 and the frame 12, thereby improving the structural stability of the smart interactive tablet 1. It is understandable that the back plate 13 may also be made of plastic. In the embodiment of the present application, there is no specific limitation on the material of the back plate 13.

[0036] The antenna assembly 14 is connected to the side of the back plate 13 away from the display screen 11. When the back plate 13 is made of metal, the back plate 13 has a gap 13A, and the antenna assembly 14 is set corresponding to the gap 13A. It can be understood that when the back plate 13 is made of plastic, the back plate 13 can also send and receive signals through the black border area 11B without setting the gap 13A. It can be understood that the gap 13A is a long strip through hole that runs through the back plate 13, and the length of the gap 13A can be determined according to the radiation wavelength of the antenna assembly 14.

[0037] In the embodiment of the present application, along the light emitting direction X, the antenna assembly 14 is located in the black-border area 11B, so that the antenna assembly 14 can transmit and receive signals in the front-back direction of the display screen 11 via the gap 13A and the black-border area 11B. Specifically, the projection of the antenna assembly 14 on the display screen 11 is at least partially located in the black-border area 11B. Exemplarily, a portion of the projection of the antenna assembly 14 on the display screen 11 may be located in the display area 11A, and another portion of the projection of the antenna assembly 14 on the display screen 11 may be located in the black-border area 11B. Exemplarily, a portion of the projection of the antenna assembly 14 on the display screen 11 may be located in the black-border area 11B, and another portion of the projection of the antenna assembly 14 on the display screen 11 may be located in the projection area of ​​the frame 13 on the display screen 11. Exemplarily, a portion of the projection of the antenna assembly 14 on the display screen 11 may be located in the display area 11A, another portion of the projection of the antenna assembly 14 on the display screen 11 may be located in the black border area 11B, and another portion of the projection of the antenna assembly 14 on the display screen 11 may be located in the projection area of ​​the frame 13 on the display screen 11. In the embodiment of the present application, since there are display elements and metal wires in the display area 11A, the frame 13 is usually made of metal, and there are no metal wires in the black border area 11B of the display screen 11, therefore, the projection of the antenna assembly 14 on the display screen 11 is located in the black border area 11B, which can reduce the metal shielding interference of the antenna assembly 14 when transmitting and receiving signals in the front and rear directions of the display screen 11, thereby improving the stability of signal transmission and reception of the antenna assembly 14. Furthermore, the antenna assembly 14 transmits and receives signals via the black border area 11B in the direction toward the front and rear of the display screen 11, which can improve the signal transmission and reception strength and signal transmission and reception efficiency compared to transmitting and receiving signals at the bottom of the frame 12; and by transmitting and receiving signals via the black border area 11B of the display screen 11, there is no need to open a hole on the front of the display screen 11, so that the front of the smart interactive tablet 1 can remain flat.

[0038] Please refer to Figure 2-5 In a specific embodiment, the antenna assembly 14 includes a circuit board 141, the circuit board 141 is connected to the side of the back plate 13 away from the display screen 11, the circuit board 141 has a slot antenna 142, and the slot antenna 142 is arranged corresponding to the slot 13A; the slot antenna 142 can receive and transmit signals through the slot 13A and the black border area 11B, which can improve the accuracy of receiving and transmitting signals; the projection of the slot antenna 142 on the back plate 13 is located in the slot 13A, so that the signal radiated by the slot antenna 142 can be radiated through the slot 13A, thereby reducing the influence of the back plate 13 on the signal, and improving the accuracy of receiving and transmitting signals by the slot antenna 142.

[0039] Please refer to Figure 2 and Figure 3In a specific embodiment, the antenna assembly 14 also includes a radio frequency chip 143, which is disposed on the circuit board 141 and connected to the slot antenna 142, so that the radio frequency chip 143 is used to feed the slot antenna 14, thereby facilitating the slot antenna 142 to transmit and receive signals, and also enabling the distance between the radio frequency chip 143 and the slot antenna 142 to be closer, thereby avoiding the loss and interference caused by the longer connecting line, and improving the signal transmission and reception efficiency of the slot antenna 142. Specifically, the radio frequency chip 143 can be connected to the slot antenna 142 through a radio frequency line to reduce the interference of interference signals on the signal exchange between the radio frequency chip 143 and the slot antenna 142, and improve the accuracy of the signal transmission and reception of the slot antenna 142. Exemplarily, the radio frequency chip 143 can be disposed on the side of the circuit board 141 away from the back plate 13, so as to facilitate the installation of the circuit board 141.

[0040] Please refer to Figure 2 and Figure 3 In a specific embodiment, the antenna assembly 14 further includes a metal shielding cover 146, which is disposed on the side of the circuit board 141 away from the back plate 13. The metal shielding cover 146 and the circuit board 141 surround a receiving cavity 146A, and the slot antenna 142 is located in the receiving cavity 146A. The metal shielding cover 146 can reduce the interference of other signals on the slot antenna 142, thereby improving the accuracy of the signal received by the slot antenna 142. Furthermore, since the metal shielding cover 146 is disposed on the side of the circuit board 141 away from the back plate 13, a resonant cavity can be formed in the receiving cavity 146A to enhance the strength of the signal emitted by the slot antenna 142.

[0041] It can be understood that multiple slot antennas 142 can be arranged at intervals, and along the light emitting direction, the projections of the multiple slot antennas 142 on the back panel 13 are all located in the same slot 13A to improve the signal receiving and sending capabilities of the antenna assembly 14, thereby improving the stability of the received and sent signals.

[0042] It can be understood that there can be multiple slot antennas 142 spaced apart, and the back panel 13 has multiple slots 13A spaced apart. Along the light emitting direction, the projections of the multiple slot antennas 142 on the back panel 13 are located one by one in the multiple slots 13A, so that the multiple slot antennas 142 can be used to transmit and receive multiple signals, so as to increase the frequency band and application function radiated by the slot antenna 142, and improve the signal transmission and reception efficiency of the antenna assembly 14.

[0043] Exemplarily, the circuit board 141 may have two slot antennas 142 so that the antenna assembly 14 can satisfy the functions of transmitting and receiving WiFi signals and Bluetooth signals of the smart interactive tablet 1 .

[0044] Exemplarily, the circuit board 141 may have four slot antennas 142 so that the antenna assembly 14 can meet the transceiver functions of the WiFi signal, the Bluetooth signal and the wireless access point (AP) signal of the smart interactive tablet 1.

[0045] Please refer to Figure 2-5 In a specific embodiment, along the width direction of the smart interactive tablet 1, the slot 13A has a first width L1, and the slot antenna 142 has a second width L2. The corresponding second width L2 can be adapted according to the wavelength of the signal radiated by the slot antenna 142, so as to meet the radiation requirements of the slot antenna 142. Specifically, the first width L1 is greater than or equal to 1mm and less than or equal to 6mm, the second width L2 is greater than or equal to 1mm and less than or equal to 6mm, and the first width L1 is greater than or equal to the second width L2, so that the slot antenna 142 can work in the WiFi frequency band and the Bluetooth frequency band. Exemplarily, the first width L1 is 5mm, and the second width L2 is 2.5mm.

[0046] It can be understood that the antenna assembly 14 also includes a board-mounted antenna and a steel sheet antenna, which are both arranged on the circuit board 141, connected to the RF chip 143, and spaced apart from the slot antenna 142, so that the antenna assembly 14 has more signal receiving and sending functions to meet different signal receiving and sending requirements.

[0047] Please refer to Figure 2 and Figure 3 In a specific embodiment, the smart interactive tablet 1 also includes a decorative piece 147, which is disposed on a side of the back panel 13 away from the display screen 11. An accommodating cavity 147A is formed between the decorative piece 147 and the back panel 13. The antenna assembly 14 is disposed in the accommodating cavity 147A. The decorative piece 147 can protect the antenna assembly 14 to reduce the probability of damage to the antenna assembly 14, thereby allowing the antenna assembly 14 to have a longer service life.

[0048] Specifically, the decorative member 147 may be made of metal or plastic. Exemplarily, when the decorative member 147 is made of metal, the decorative member 147 has an avoidance groove (not shown in the figure) so that the onboard antenna and the steel sheet antenna can be exposed through the avoidance groove, so that the onboard antenna and the steel sheet antenna can transmit and receive signals through the avoidance groove, thereby improving the stability of the onboard antenna and the steel sheet antenna in transmitting and receiving signals.
