Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In the description of this application, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0029] In addition, some of the above terms may be used to express other meanings in addition to indicating orientation or positional relationship. For example, the term "on" may also be used to express a certain dependency or connection relationship in some cases. For those skilled in the art, the specific meanings of these terms in this utility model can be understood according to specific circumstances.

[0030] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0031] The present application provides an electronic device, including a shell and an antenna transmission device, wherein the antenna transmission device is arranged inside the shell, and the shell is mainly used to protect and seal the antenna transmission device to prevent the internal antenna transmission device from being interfered with by the outside. The antenna transmission device, as an electronic component, is mainly used to improve the efficiency of receiving and sending wireless signals to achieve stability and speed of wireless connection of the electronic device.

[0032] It should be noted that the electronic device may be a sensor, a router, or other product that can transmit wireless signals.

[0033] See also Figure 1 and Figure 2 The antenna transmission device includes a first circuit board 1 and a second circuit board 2. The first circuit board 1 includes a first wiring area 11 arranged at the top thereof and a first functional area 12 arranged at the bottom thereof. The first wiring area 11 is provided with a first wire 111, and the first wire 111 is connected to the first functional area 12. The first wire 111 is used for sending and receiving signals. The second circuit board 2 includes a second wiring area 21 arranged at the top thereof and a second functional area 22 arranged at the bottom thereof. The second wiring area 21 is provided with a second wire 211, and the second wire 211 is connected to the second functional area 22. The first circuit board 1 and the second circuit board 2 are arranged opposite to each other and are electrically connected. The first wire 111 is arranged in a direction away from the second wire 211.

[0034] It should be noted that electronic devices are usually wireless products with specific functions, such as human body sensors, which can be used to detect human movement and perceive ambient light. Such electronic devices also include functional components to detect environmental changes and transmit environmental information to the microcontroller unit, which then sends the information out via wireless messages. Therefore, in addition to setting up circuit routing for receiving and sending signals, the antenna transmission device also needs to set up circuit routing for functional components.

[0035] In practical applications, the antenna transmission device is divided into a first circuit board 1 and a second circuit board 2, the first circuit board 1 is used to receive and send signals, and the second circuit board 2 is used to set functional components; during assembly, the first circuit board 1 and the second circuit board 2 can be stacked together and placed in a housing, which effectively reduces the size and volume of the electronic device; the first circuit board 1 includes a first wiring area 11, the first wiring area 11 is provided with a first wire 111, the first wire 111 is used to receive and send wireless signals, and the second circuit board 2 includes a second wiring area 21, the second wiring area 21 is provided with a second wire 211, and the second wire 211 can be used to connect some functional components, such as indicator lights 32 or sensors 31 and other components, to play a prompt or monitoring function; further, the first wire 111 is set in a direction away from the second wire 211, and the distance between the first wire 111 and the second wire 211 is increased. Such a setting can reduce the shielding effect of the second wire 211 on the first wire 111 after the first circuit board 1 and the second circuit board 2 are stacked together and placed in the housing, which can not only reduce the volume of the device, but also improve the wireless transmission efficiency of the first wire 111.

[0036] Compared with the prior art, the present application divides the antenna transmission device into a first circuit board 1 and a second circuit board 2, and the first circuit board 1 and the second circuit board 2 are stacked together and placed in a housing, which effectively reduces the volume of the circuit board; and the first wire 111 is arranged in a direction away from the second wire 211 to reduce the shielding effect of the second wire 211 on the first wire 111, thereby improving the wireless transmission efficiency. The electronic device using this device realizes the stability of the wireless transmission function of the electronic device, and the electronic device can be designed to be smaller in size and volume. The smaller electronic device is convenient to be integrated into other smart devices, such as smart phones or drones, etc., thereby improving the practicality of the electronic device.

[0037] See also Figure 1 and Figure 2 The first routing area 11 includes a first left area 112, a first middle area 113 and a first right area 114 which are interconnected from left to right, and the first conductor 111 is at least partially located in the first left area 112; the second routing area 21 includes a second left area 212, a second middle area 213 and a second right area 214 which are interconnected from left to right, and the second conductor 211 is arranged in the second middle area 213.

[0038] In one embodiment, when the first circuit board 1 and the second circuit board 2 are stacked, the first functional area 12 is usually opposite to the second functional area 22, and the first routing area 11 is opposite to the second routing area 21. In this way, the first left area 112 may be opposite to the second left area 212 or the second right area 214. Therefore, the second wire 211 is set in the second middle area 213 of the second routing area 21, and the first wire 111 located in the first left area 112 will not be opposite to the second wire 211. This arrangement makes it more convenient to stack the first circuit board 1 and the second circuit board 2, and also prevents the second wire 211 from blocking the signal of the first wire 111.

[0039] See again Figure 2 In one embodiment, the antenna transmission device further includes a monitoring module 3, which is disposed in the second middle area 213, and the second wire 211 is respectively connected to the monitoring module 3 and the second functional area 22, and the monitoring module 3 is used to detect the environment.

[0040] In practical applications, the electronic device can be a human body sensor, which is a product used to detect human body movement; therefore, the functional component on the electronic device can be a monitoring module 3, which is used to detect environmental changes and transmit environmental information to the microcontroller unit, which then sends the environmental information through a wireless message to realize the function of the electronic device to detect human body movement. The monitoring module 3 is arranged in the second middle area 213, so that the second wire 211 is connected to the monitoring module 3 to realize the monitoring function of the electronic device.

[0041] It is understandable that in some other embodiments, the electronic device may also be a wireless product with other functions, such as a router. When the electronic device is a router, it does not have a monitoring function, so the monitoring module 3 may not be set. This application does not limit the type of electronic device.

[0042] In one embodiment, the monitoring module 3 may include a sensor 31 and an indicator light 32, and the second wire 211 includes a sensing wire 2113 and a lighting wire 2114, the sensing wire 2113 is respectively connected to the sensor 31 and the second functional area 22, and the lighting wire 2114 is respectively connected to the indicator light 32 and the second functional area 22.

[0043] Among them, the sensing wire 2113 is used to connect the sensor 31, and the lighting wire 2114 is used to connect the indicator light 32, so as to ensure the normal electrical connection between the sensor 31 and the indicator light 32; the sensor 31 can be a light intensity sensor for monitoring the ambient light intensity, and the indicator light 32 is used to display the current working status of the electronic device, so as to prompt the user whether the device is working normally.

[0044] In some other embodiments, the monitoring module 3 may also include other components, such as a display screen, which can be used to display the current monitoring data of the device. The monitoring module 3 can be set according to actual needs, and this application does not limit this.

[0045] See again Figure 1 , for the convenience of description, Figure 1 Where X represents the length direction, and Y represents the width direction; in one embodiment, the first conductive line 111 includes a first portion 1111 and a second portion 1112, one end of the first portion 1111 is connected to the first functional area 12, and the other end is connected to the second portion 1112, the first portion 1111 is arranged in parallel with the width direction Y of the first routing area 11, and the first portion 1111 is located in the first left area 112, the second portion 1112 is arranged in parallel with the length direction X of the first routing area 11, and the second portion 1112 is located at the top of the first routing area 11.

[0046] In practical applications, the first conductor 111 is composed of a first portion 1111 and a second portion 1112 which are vertically connected to each other. In this way, the first portion 1111 and the second portion 1112 of the first conductor 111 are both arranged in a straight line, and the bending section is eliminated, so as to avoid the first conductor 111 from being close to the second conductor 211 as much as possible; the first portion 1111 is arranged in parallel with the width direction Y of the first routing area 11, and the second portion 1112 is arranged in parallel with the length direction X of the first routing area 11. This arrangement makes the routing of the first conductor 111 more regular. At the same time, the first portion 1111 is located in the first left side area 112. Specifically, the first portion 1111 is located on the left side of the first left side area 112, which increases the distance between the first portion 1111 and the second conductor 211. The second portion 1112 is located at the top of the first routing area 11, which also increases the distance between the second portion 1112 and the second conductor 211, further reducing the signal of the first conductor 111 being blocked by the second conductor 211, thereby improving the efficiency of the first conductor 111 in sending and receiving signals.

[0047] See again Figure 2 , for the convenience of description, Figure 2 X represents the length direction, and Y represents the width direction; in one embodiment, the second conductive wire 211 includes a third portion 2111 and a fourth portion 2112, the third portion 2111 is parallel to the width direction Y of the second routing area 21, the fourth portion 2112 is bent and extended toward the second right side area 214, one end of the third portion 2111 is connected to the second functional area 22, and the other end is connected to the fourth portion 2112, and the fourth portion 2112 is used to connect to the monitoring module 3.

[0048] In practical applications, the second conductor 211 includes a third portion 2111 and a fourth portion 2112 that are interconnected. The third portion 2111 is parallel to the width direction Y of the second routing area 21, and can also play the role of the first portion 1111 away from the first conductor 111. At the same time, the fourth portion 2112 is bent toward the second right side area 214, that is, it is bent in a direction away from the first portion 1111, further avoiding the fourth portion 2112 from blocking the signal of the first conductor 111.

[0049] In one embodiment, the first left area 112 and the second right area 214 are disposed opposite to each other, the first middle area 113 and the second middle area 213 are disposed opposite to each other, and the first right area 114 and the second left area 212 are disposed opposite to each other.

[0050] In practical applications, the first circuit board 1 has a first front side and a first back side, and the side provided with the first wire 111 is called the first front side. Of course, the second circuit board 2 also has a second front side and a second back side, and the side provided with the second wire 211 is called the second front side. When the first circuit board 1 and the second circuit board 2 are stacked, in order to further prevent the second wire 211 from blocking the signal of the first wire 111, the first front side and the second front side are arranged back to back, and the first back side and the second back side are arranged facing each other. In this way, after the first circuit board 1 and the second circuit board 2 are stacked, the first left area 112 and the second right area 214 are arranged opposite to each other, and the first right area 114 and the second left area 212 are arranged opposite to each other, so that the first wire 111 can be ensured to be as far away from the second wire 211 as possible, the distance between the first wire 111 and the second wire 211 is increased, and the shielding effect of the second wire 211 on the first wire 111 is reduced.

[0051] It should be noted that when the first circuit board 1 and the second circuit board 2 are stacked together, the first front side and the second front side are arranged back to back specifically as follows: the first front side is located on the side of the first circuit board 1 away from the second circuit board 2, and the second front side is located on the side of the second circuit board 2 away from the first circuit board 1; the first back side and the second back side are arranged facing each other specifically as follows: the first back side is located on the side of the first circuit board 1 close to the second circuit board 2, and the second back side is located on the side of the second circuit board 2 close to the first circuit board 1. The relative arrangement in the present application can be understood as the projection areas of the two areas on the same plane completely overlap or approximately completely overlap, for example, taking the plane where the first left side area 112 is located as the projection plane, the projection area of ​​the second right side area 214 on this projection plane is approximately completely overlapped with the first left side area 112, so that the first left side area 112 and the second right side area 214 are relatively arranged.

[0052] See again Figure 1 and Figure 2In one embodiment, the first right area 114 is provided with a first through hole 15 , and the second right area 214 is provided with a second through hole 25 ; the first through hole 15 is arranged opposite to the second left area 212 , and the second through hole 25 is arranged opposite to the first left area 112 .

[0053] In actual application, the first right area 114 is provided with a first perforation 15, and the second right area 214 is provided with a second perforation 25. The first perforation 15 and the second perforation 25 serve to distinguish. When stacking the first circuit board 1 and the second circuit board 2, the positions of the first right area 114 and the second right area 214 can be clearly identified through the first perforation 15 and the second perforation 25, which is convenient for installers to assemble, and the first left area 112 and the second right area 214 can be quickly and accurately arranged relative to each other. The first right area 114 and the second left area 212 are arranged relative to each other, which improves assembly efficiency and saves time and effort.

[0054] In one embodiment, the first through hole 15 may also be provided in the first left area 112, and the second through hole 25 may also be provided in the second left area 212, which can help the installer to distinguish and identify the positions of the first left area 112 and the second left area 212, thereby achieving quick assembly.

[0055] It can be understood that the first perforation 15 can be set in any one of the first left area 112 and the first right area 114, and the second perforation 25 can be set in any one of the second left area 212 and the second right area 214, both of which can play the role of the above-mentioned distinction and identification.

[0056] See also Figure 3 and Figure 4 The antenna transmission device also includes a first grounding member 13 and a second grounding member 23. The first grounding member 13 is arranged on a side of the first circuit board 1 facing the second circuit board 2 and is located in the first functional area 12. The second grounding member 23 is arranged on a side of the second circuit board 2 facing the first circuit board 1 and is located in the second functional area 22. The first grounding member 13 and the second grounding member 23 are electrically connected.

[0057] It should be noted that grounding is usually required on circuit boards. Grounding is an electrical engineering term that refers to connecting a part of an electrical device or circuit to the earth or other large conductors (such as the metal structure of a building) to provide a common reference potential. This reference potential is usually considered to be the zero voltage point to ensure the stability and safety of the circuit.

[0058] In practical applications, connecting the first grounding piece 13 on the first circuit board 1 and the second grounding piece 23 on the second circuit board 2 together can ensure that the two circuit boards have the same common reference point, thereby ensuring the correct operation of the circuit and the accurate transmission of the signal. At the same time, since the signals on different circuit boards may interfere with each other, grounding can be used as part of the electromagnetic shielding. Connecting the grounding pieces of the two circuit boards together can jointly form an electromagnetic shielding environment with better shielding effect, thereby preventing external magnetic fields from interfering with the normal transmission function of the device.

[0059] See again Figure 3 and Figure 4 The antenna transmission device also includes a third grounding member 14 and a fourth grounding member 24. The third grounding member 14 is arranged on a side of the first circuit board 1 facing the second circuit board 2 and is located in the first functional area 12; the fourth grounding member 24 is arranged on a side of the second circuit board 2 facing the first circuit board 1 and is located in the second functional area 22; the third grounding member 14 is electrically connected to the fourth grounding member 24.

[0060] Specifically, the third grounding member 14 is arranged at a position of the first circuit board 1 close to the first wire 111. The third grounding member 14 and the fourth grounding member 24 increase the area of ​​the grounding plane between the first circuit board 1 and the second circuit board 2. The larger grounding plane can provide lower impedance and better electromagnetic shielding effect, so that the loop impedance between the antenna transmission device and the ground is smaller, thereby ensuring the integrity and accuracy of the wireless signal.

[0061] In one embodiment, the first grounding member 13 and the second grounding member 23 can be connected by a pin header; the pin header connection is more flexible in design and can be modularly designed or have pluggable circuit boards, which is suitable for connecting multiple circuit boards and provides a tighter connection.

[0062] It should be noted that the pin header connection refers to the use of one or more rows of pin headers to connect with corresponding holes. Specifically, one of the first grounding piece 13 and the second grounding piece 23 is one or more rows of pin headers, and the other of the first grounding piece 13 and the second grounding piece 23 is one or more rows of jacks. The pin headers are connected with the jacks to achieve a grounding connection between the first grounding piece 13 and the second grounding piece 23.

[0063] In one embodiment, the third grounding member 14 and the fourth grounding member 24 can be connected by a pin connection. Since the third grounding member 14 is arranged close to the first wire 111, the pin grounding method can save the design area of ​​the third grounding member 14. At the same time, the pin connection can provide a very low grounding impedance, which is beneficial to the transmission efficiency of the wireless signal.

[0064] It should be noted that the ejector pin connection usually refers to the use of an ejector pin (metal column) to connect with the corresponding hole. Specifically, one of the third grounding member 14 and the fourth grounding member 24 is an ejector pin, and the other of the third grounding member 14 and the fourth grounding member 24 is a socket. The ejector pin and the socket are connected to achieve a grounding connection between the third grounding member 14 and the fourth grounding member 24.

[0065] It can be understood that the first grounding member 13 and the third grounding member 14 are both arranged on the first reverse side of the first circuit board 1, and the second grounding member 23 and the fourth grounding member 24 are both arranged on the second reverse side of the second circuit board 2. When the first circuit board 1 and the second circuit board 2 are stacked, the first reverse side and the second reverse side are arranged opposite to each other, so as to facilitate the connection between the first grounding member 13 and the second grounding member 23, and the connection between the third grounding member 14 and the fourth grounding member 24.

[0066] In one embodiment, the first grounding member 13 and the third grounding member 14 are both disposed in the first functional area 12 and opposite to the first left area 112 , and the second grounding member 23 and the fourth grounding member 24 are both disposed in the second functional area 22 and opposite to the second right area 214 .

[0067] Since the first reverse side and the second reverse side are arranged opposite to each other, the first grounding member 13 and the third grounding member 14 are arranged opposite to the first left area 112, and the second grounding member 23 and the fourth grounding member 24 are arranged opposite to the second right area 214. When stacked, the first grounding member 13 and the second grounding member 23 are positioned opposite to each other, and the third grounding member 14 and the fourth grounding member 24 are positioned opposite to each other. This facilitates the grounding connection between the two circuit boards, reasonably arranges the space design on the circuit board, and is conducive to saving the design area of ​​the circuit board.

[0068] In one embodiment, the electronic device takes a human body sensor as an example, and describes the functions of the present invention in detail in combination with the above-mentioned antenna transmission device.

[0069] Figure 5 The working principle diagram of the human body sensor is shown. The human body sensor is a product that detects human body movement by sensing human body infrared radiation. Its working principle is: after the passive infrared radiation probe detects human body movement, it outputs an interrupt signal to the microcontroller unit through the signal conditioning circuit. After the microcontroller unit receives the interrupt signal from the signal conditioning circuit, it sends a wireless message through the radio frequency antenna; or after the light intensity sensor 31 measures the change in the reduced ambient light, it sends the light intensity value through a wireless message; at the same time, under normal working conditions, the device in this application will also send a handshake signal at intervals of about 1 hour. The handshake signal is used to establish, maintain and terminate a communication session between two communication entities to ensure that the two systems can coordinate and respond to each other during data transmission.

[0070] As shown in Table 1, the human body sensor in the prior art can achieve an antenna transmission efficiency of no more than 28% at most. However, with the antenna transmission device of the present application, as shown in Table 2, the antenna transmission efficiency of the human body sensor at a frequency of 2500 MHz can be increased to about 40%, and the transmission efficiency of the overall device exceeds 36%, which greatly improves the success rate of sending and receiving wireless signals, reduces the probability of wireless signal retransmission, reduces product power consumption, and makes the system more stable.
