Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of electronic product antennas, and in particular to an antenna structure, a housing and an electronic product. Background Art
[0002] To achieve good visual effects, laptop displays are moving towards narrow or even borderless bezels. Given the high display screen ratio, antennas are not ideally designed on the display screen borders and generally need to be placed in the space around the laptop system.
[0003] To enhance the aesthetics and thinness of laptop computers, they typically use full metal casings (such as magnesium-aluminum alloy or aluminum-magnesium alloy). With the advancement of wireless communication technology, the number of antennas is increasing, but the effective area available for antennas is shrinking. Furthermore, full metal casings shield electromagnetic waves, making antenna design challenging. Currently, common antenna designs for full metal casings include:
[0004] Maintain antenna clearance. Early assessments should reserve the required clearance for the antenna. For example, if the antenna is installed on the display side, a clearance area must be left on the display side's housing. If the antenna is installed on the system side, a clearance area must be left on the system side's housing. Furthermore, slots must be opened in the all-metal housing to allow the antenna radiation pattern to pass through and radiate through the slots. This approach compresses the configuration and placement space of various components within the system.
[0005] Alternatively, the antenna can be placed at the hinge to address the lack of space between the display and system terminals. However, this approach requires a larger hinge, which increases the distance between the display and system terminals, reducing the laptop's aesthetics and user comfort.
[0006] In the above two methods, after the position and size of the antenna are determined, the environment around the antenna is difficult to change, which is not conducive to product design and update. Utility Model Content

[0032] In order to make the purpose, features, and advantages of the present invention more obvious and easy to understand, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative efforts shall fall within the scope of protection of the present invention.
[0033] An embodiment of the utility model provides an antenna structure, including a foot pad mounting structure, a foot pad body and an antenna body; the foot pad mounting structure is used to connect with the foot pad body, such as the foot pad mounting structure is a shell of an electronic product, a part of the foot pad body is connected to the mounting groove of the foot pad mounting structure, and the antenna body is arranged on the foot pad body, thereby integrating the antenna into the foot pad.
[0034] The following describes in detail the various structures in the antenna structure provided by the embodiment of the present invention, as well as the positional relationship and connection relationship between the various structures, in conjunction with the accompanying drawings.
[0035] like Figures 1 to 6 As shown, the foot pad mounting structure 10 includes a mounting groove 11. The shape of the mounting groove 11 is defined according to the foot pad body 20. For example, the foot pad body 20 is in the shape of an elongated strip. Therefore, the corresponding mounting groove 11 is also in the shape of an elongated strip. The mounting groove 11 has a certain depth. The foot pad body 20 includes a connecting end 21. The connecting end 21 is used to be inserted into the mounting groove 11. The foot pad body 20 also includes a supporting end, which is connected to the connecting end 21. The connecting end 21 is placed in the mounting groove 11, and the supporting end is located outside the mounting groove 11 to provide an anti-slip support.
[0036] The size range of the mounting groove 11 is the same as or similar to that of the connecting end 21. When the two are connected, the connecting end 21 is squeezed into the mounting groove 11. The inner size design of the mounting groove 11 must comply with the operating frequency band of the WLAN of the electronic product.
[0037] For example, the connection end 21 is in a rectangular parallelepiped shape, and the length of the connection end 21 ranges from 50 mm to 70 mm, the width ranges from 3 mm to 8 mm, and the height ranges from 3 mm to 8 mm.
[0038] The antenna body 30 is arranged at the connecting end 21 and is used to be inserted into the mounting groove 11 synchronously with the connecting end 21. When the connecting end 21 is inserted into the mounting groove 11, there is a certain accommodation space between the side where the antenna body 30 is located and the inner wall of the mounting groove 11. The antenna body 30 is arranged in the accommodation space to avoid squeezing the antenna body 30. For example, an inward-concave groove structure is provided on the connecting end 21 and / or the inner wall of the mounting groove 11 to form an accommodation space; after setting the accommodation space, the protruding electronic components on the antenna body 30 are prevented from being squeezed during installation, thereby ensuring the integrity of the antenna body 30.
[0039] The antenna structure is integrated within mounting slot 11, outside of foot-mounted mounting structure 10. If foot-mounted mounting structure 10 is the housing of an electronic product, this design effectively saves space within the electronic product housing and reduces space restrictions on the antenna structure's size. For example, the antenna structure can be used in conjunction with a coupled antenna and employ antenna types such as PIFA, Monopole, and Loop.
[0040] In the embodiment of the present invention, the circuit board 31 includes a flexible circuit board, the connector 32 is provided on one side of the flexible circuit board, and the other side of the flexible circuit board is bonded to the side wall of the connecting end 21 .
[0041] For example, an installation area is set at the connection end 21. For example, a accommodating space as large as the flexible circuit board can be set in the installation area, and the other side of the flexible circuit board is bonded to the area. The flexible circuit board has high plasticity and a small thickness. It is combined with the connection end 21 and occupies a small space.
[0042] For example, a positioning structure is provided on the side of the connection end 21, and the circuit board 31 is connected to the side wall of the connection end 21 through the positioning structure. For example, the positioning structure includes a protrusion 22 and a positioning hole 35. The protrusion 22 is provided on the side of the connection end 21, and the positioning hole 35 is provided on the flexible circuit board. When connecting, the positioning hole 35 can be placed on the protrusion 22, thereby achieving a quick and accurate installation connection between the flexible circuit board and the connection end 21.
[0043] For example, the circuit board 31 is rectangular in shape, and the length of the circuit board 31 is in a range of 10 mm to 20 mm, and the width is in a range of 2 mm to 4 mm.
[0044] Continue to refer Figures 1 to 6 As shown, in this embodiment of the present invention, a connector 32, electronic components, and a spring 33 are provided on the flexible printed circuit board. The connector 32 is used to connect to the mainboard via a connecting cable. For example, the connector 32 includes a coaxial cable interface, and the connecting cable includes a coaxial cable 34. One end of the coaxial cable 34 is connected to the coaxial cable interface, and the other end is used to connect to the mainboard.
[0045] For example, after the connection end 21 is connected to the mounting slot 11, an opening is provided at the bottom of the mounting slot 11. This opening allows the coaxial cable 34 to pass through the mounting slot 11 and connect to the WLAN module on the motherboard. For example, the identification or color of the coaxial cable 34 can be used to distinguish the connected antenna structure, thereby reducing the chance of incorrect installation of the antenna body 30.
[0046] In this embodiment of the present invention, spring 33 is compressed by and engages with mounting slot 11 to form an antenna feed point. Spring 33 is a metal spring structure and is spaced apart from connector 32 on the flexible circuit board. This means that there is space on the flexible circuit board between connector 32 and spring 33 for circuitry.
[0047] A π-shaped circuit 36 is provided within this space. Specifically, a 0402-sized PAD is first retained on the flexible printed circuit board, a 0402-sized 0Ω resistor is then connected in series, and another 0402-sized PAD is retained, thereby forming the π-shaped circuit 36. The resistor R, inductor L, and capacitor C are arranged according to the RLC oscillation frequency formula to adjust the characteristic curve of the antenna so that the characteristics of the antenna structure can meet the required frequency band.
[0048] The present invention also provides a housing including the antenna structure. A portion of the housing is a foot pad mounting structure 10, on which a mounting slot 11 is provided. The size of the mounting slot 11 is determined based on the performance of the antenna structure and the support effect of the foot pad.
[0049] For example, the shell includes an inner side and an outer side, the notch of the mounting slot 11 is located on the outer side of the shell, and the connecting line (coaxial cable) connected to the antenna structure connector 32 passes through the shell and is located on the inner side of the shell, and the connecting line is connected to the WLAN module on the main board inside the shell.
[0050] The present invention also provides an electronic product comprising the aforementioned antenna structure or housing. For example, the electronic product is a laptop computer. The laptop computer comprises a display terminal and a system terminal. A motherboard is disposed within the system terminal, and a foot pad is disposed at the bottom of the bottom housing of the system terminal. The antenna structure is disposed at the foot pad location.
[0051] The number of antenna structures is not limited to one, and may also be multiple. For example, multiple antenna structures may be provided on one foot pad, or multiple antenna structures may be provided on multiple foot pads.
[0052] The utility model provides an antenna structure, a housing, and an electronic product. The antenna structure is arranged at the position of a foot pad, which can effectively save space inside the electronic product housing and improve the impact of space limitations on the antenna structure. It can also avoid the antenna structure from overlapping with other electronic components, prevent signal coupling, and reduce noise generation. The antenna structure is combined with the foot pad, which has higher versatility during installation and is simple and quick to assemble, which can improve assembly speed and reduce labor and warehousing costs.
