Description

Technical Field

[0001] This application relates to the field of data transmission technology, specifically to an antenna device and a communication terminal. Background Technology

[0002] Antenna devices, as an indispensable part of wireless equipment, undertake the crucial tasks of converting high-frequency current into electromagnetic waves for transmission, and converting received electromagnetic waves into high-frequency current. Whether in communications, broadcasting, television, radar, or navigation, antennas play a vital role. However, in the design process of antenna devices, the design of the interface location is often an easily overlooked yet crucial aspect.

[0003] Existing antenna devices suffer from significant design flaws in their interface placement, primarily affecting the stability of the connection between the connector and the interface. Due to this flawed design, the connector is highly susceptible to collisions with external objects when it is attached. These collisions can lead to loosening of the connection and, in severe cases, even detachment. Such problems not only severely interfere with the normal operation of the antenna but may also further degrade the overall performance of the equipment, and in extreme cases, even cause a complete communication outage, resulting in immeasurable and serious consequences. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, this application provides an antenna device and a communication terminal.

[0005] The specific technical solution is as follows:

[0006] An antenna device includes a base, a top cover, and an antenna module, wherein a receiving cavity is formed between the base and the top cover, and the antenna module is located within the receiving cavity;

[0007] The base includes a main body and an extension extending outward from the top of the main body. The base is fixed to the support surface by the main body and connected to the top cover by the extension. The side wall of the main body has a concave portion and a through hole is provided on the concave portion. The antenna module is equipped with an antenna interface. The antenna interface extends into the receiving space through the through hole and is electrically connected to the antenna module.

[0008] Wherein, the projection of the extension portion on the support surface covers the projection of the main body portion on the support surface, and the distance L between the projection of the through hole on the support surface and the projection of the extension portion on the support surface is between 2cm and 5cm.

[0009] In one embodiment, the axes of the body portion and the extension portion coincide;

[0010] The projections of the main body and the extension on the support surface are both circular, or the projections of the main body and the extension on the support surface are both square, or one of the projections of the main body and the extension on the support surface is circular and the other is square.

[0011] In one embodiment, the antenna device further includes at least one first elastic element located outside the connection between the extension portion and the top cover;

[0012] When the number of the first elastic element is one, the first elastic element is arranged around the outside of the connection between the extension and the top cover;

[0013] When there are two or more first elastic elements, the two or more first elastic elements are spaced apart from each other and arranged around the outside of the connection between the extension and the top cover.

[0014] In one embodiment, the first elastic member is provided with a first groove and a second groove whose groove directions are opposite to each other, the top cover has a first connecting portion located in the first groove, and the outer extension has a first extension portion located in the second groove;

[0015] The top cover also has a second connecting portion located inside the first connecting portion, and the outer extension portion also has a second extension portion located inside the first extension portion. A snap-fit ​​connection structure is provided between the second connecting portion and the second extension portion.

[0016] In one embodiment, a positioning block is provided in the second groove, and a positioning groove is provided on the first extension, with the positioning block located in the positioning groove.

[0017] In one embodiment, the top cover protrudes to the side away from the base to form an outwardly convex arc-shaped top cover.

[0018] In one embodiment, the top cover includes a first connecting portion and an arc-shaped portion. The top cover is connected to the outer extension portion through the first connecting portion. The arc-shaped portion protrudes to the side away from the base. The connection between the first connecting portion and the arc-shaped portion is provided with a rounded corner structure.

[0019] In one embodiment, a second elastic element is provided at the bottom of the main body, and the main body contacts the support surface through the second elastic element.

[0020] In one embodiment, the base is made of a metal material;

[0021] And / or, the top cover is made of at least one of PC and PBT materials.

[0022] The communication terminal includes the antenna device as described in any of the embodiments above.

[0023] This application has at least the following beneficial effects:

[0024] This application provides an antenna device, including a base, a top cover, and an antenna module. A receiving cavity is formed between the base and the top cover, and the antenna module is located within the receiving cavity. The base includes a main body and an extension extending outward from the top of the main body. The base is fixed to a support surface through the main body and connected to the top cover through the extension. The sidewall of the main body has a recess, and a through hole is provided on the recess. The antenna module is equipped with an antenna interface, which extends into the receiving space through the through hole and is electrically connected to the antenna module. The projection of the extension on the support surface covers the projection of the main body on the support surface, and the distance L between the projection of the through hole on the support surface and the projection of the extension on the support surface is between 2cm and 5cm.

[0025] This application also provides a communication terminal, including the antenna device described above.

[0026] This application places the through-hole on the side wall of the main body, which avoids occupying extra space at the top or bottom of the antenna, making the overall antenna structure more compact. It also prevents the antenna connector and antenna interface from directly obstructing the antenna's radiation direction, reducing the impact on antenna radiation performance.

[0027] Secondly, this application ensures that the projection of the extension portion on the support surface covers the projection of the main body portion on the support surface, that is, the outer diameter of the extension portion is greater than or equal to the outer diameter of the main body portion, so that a receiving groove is formed between the extension portion, the recessed portion and the support surface to provide a receiving position for the antenna connector. When the antenna connector is connected to the antenna interface, the extension portion can effectively cover the antenna connector, avoiding direct collision between the antenna connector and external objects, reducing the risk of connector detachment or damage caused by collision, ensuring that the antenna device can continuously and stably receive and transmit signals, and improving the reliability of the antenna device.

[0028] Furthermore, by optimizing the spatial layout parameters of the through hole and the extension portion, this application limits the distance L between the projection of the through hole on the support surface and the projection of the extension portion on the support surface to ≥2cm, thereby ensuring that the antenna connector can be completely placed in the receiving groove formed by the extension portion, the concave portion and the support surface. This prevents the end of the antenna connector away from the antenna interface from being exposed in the receiving groove, avoids direct collision between the antenna connector and external objects, and further improves the stable connection between the antenna connector and the antenna interface.

[0029] Furthermore, by optimizing the spatial layout parameters of the through hole and the extension portion, this application limits the distance L between the projection of the through hole on the support surface and the projection of the extension portion on the support surface to ≤5cm, which can significantly compress the lateral spatial redundancy of the antenna device, reduce the invalid volume ratio caused by structural gaps, help ensure the miniaturization and lightweight of the antenna device, and make the overall proportions harmonious and aesthetically pleasing.

Detailed Implementation

[0041] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0042] In the description of this application, it should be noted that the terms "vertical", "up", "down", "horizontal", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0043] In the description of this application, it should also be noted that, unless otherwise expressly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0044] Existing antenna devices suffer from significant design flaws in their interface placement, primarily affecting the stability of the connection between the connector and the interface. Due to this flawed design, the connector is highly susceptible to collisions with external objects when it is attached. These collisions can lead to loosening of the connection and, in severe cases, even detachment. Such problems not only severely interfere with the normal operation of the antenna but may also further degrade the overall performance of the equipment, and in extreme cases, even cause a complete communication outage, resulting in immeasurable and serious consequences.

[0045] Based on this, this application provides an antenna device, such as... Figures 1 to 8As shown, it includes a base 1, a top cover 2 and an antenna module 4. A receiving cavity 3 is formed between the base 1 and the top cover 2, and the antenna module 4 is located inside the receiving cavity 3.

[0046] The base 1 includes a main body 11 and an extension 12 extending outward from the top of the main body 11. The base 1 is fixed to the support surface through the main body 11 and connected to the top cover 2 through the extension 12. The side wall 111 of the main body has a recess 112 and a through hole 113 is provided on the recess 112. The antenna module 4 is equipped with an antenna interface 5. The antenna interface 5 extends into the receiving space through the through hole 113 and is electrically connected to the antenna module 4.

[0047] The projection of the extension portion 12 on the support surface covers the projection of the main body portion 11 on the support surface, and the distance L between the projection of the through hole 113 on the support surface and the projection of the extension portion 12 on the support surface is between 2cm and 5cm.

[0048] This application places the through-hole 113 on the side wall 111 of the main body, which avoids occupying extra space at the top or bottom of the antenna, making the overall antenna structure more compact. It also prevents the antenna connector and antenna interface 5 from directly obstructing the antenna radiation direction, reducing the impact on antenna radiation performance.

[0049] Secondly, this application ensures that the projection of the extension portion 12 on the support surface covers the projection of the main body portion 11 on the support surface, that is, the outer diameter of the extension portion 12 is greater than or equal to the outer diameter of the main body portion 11, so that a receiving groove is formed between the extension portion 12, the recessed portion 112 and the support surface, providing a receiving position for the antenna connector. When the antenna connector is connected to the antenna interface 5, the extension portion 12 can effectively cover the antenna connector, avoiding direct collision between the antenna connector and external objects, reducing the risk of connector detachment or damage due to collision, ensuring that the antenna device can continuously and stably receive and transmit signals, and improving the reliability of the antenna device.

[0050] Furthermore, by optimizing the spatial layout parameters of the through hole 113 and the extension portion 12, this application limits the distance L between the projection of the through hole 113 on the support surface and the projection of the extension portion 12 on the support surface to ≥2cm. This further ensures that the antenna connector can be completely placed in the receiving groove formed by the extension portion 12, the recessed portion 112 and the support surface, preventing the end of the antenna connector away from the antenna interface 5 from being exposed in the receiving groove, avoiding direct collision between the antenna connector and external objects, and further improving the stable connection between the antenna connector and the antenna interface 5.

[0051] Furthermore, by optimizing the spatial layout parameters of the through hole 113 and the extension portion 12, this application limits the distance L between the projection of the through hole 113 on the support surface and the projection of the extension portion 12 on the support surface to ≤5cm. This can significantly compress the lateral spatial redundancy of the antenna device, reduce the ineffective volume ratio caused by structural gaps, help ensure the miniaturization and lightweighting of the antenna device, and make the overall proportions harmonious and aesthetically pleasing.

[0052] In one embodiment, the distance L between the projection of the through hole 113 on the support surface and the projection of the extension portion 12 on the support surface is between 2.5cm and 4cm.

[0053] like Figure 3 and Figure 6 As shown, in one embodiment, the Y-axis of the body portion 11 and the extension portion 12 coincides. This embodiment makes the mass distribution of the extension portion 12 and the body portion 11 more uniform, reducing the vibration sensitivity caused by the shift in the center of gravity. At the same time, it makes the overall structure have a near-axisymmetric distribution, resulting in a high aesthetic appeal.

[0054] like Figure 6 As shown, in one embodiment, the projections of both the body portion 11 and the extension portion 12 onto the support surface are circular. Specifically, the outer diameter of the extension portion 12 is R, the distance from the through hole 113 to the axis X of the body portion 11 is A, and the distance L between the projection of the through hole 113 onto the support surface and the projection of the extension portion 12 onto the support surface is constituted by the following formula: L = RA.

[0055] In one embodiment, the projections of the body portion 11 and the extension portion 12 onto the support surface are both square.

[0056] In one embodiment, the projections of the body portion 11 and the extension portion 12 onto the support surface are either circular or square.

[0057] like Figures 1 to 3 As shown, in one embodiment, the antenna device further includes at least one first elastic element 6, which is located on the outer side of the connection between the extension portion 12 and the top cover 2. By providing the first elastic element 6 on the sidewall of the antenna device, this application can effectively absorb collision energy, reduce impact damage to the internal structure, and reduce performance fluctuations caused by vibration.

[0058] Specifically, the first elastic element 6 is a silicone ring, but it is not limited to this.

[0059] like Figures 1 to 2As shown, in one embodiment, there is one first elastic member 6, which is arranged around the outer side of the connection between the extension portion 12 and the top cover 2. This embodiment enables the first elastic member 6 to be arranged around the side wall of the antenna device, achieving 360° wrapping of the side wall of the antenna device and realizing multi-angle structural protection; it also helps to improve the sealing of the connection between the extension portion 12 and the top cover 2, and improves the waterproof and dustproof performance of the antenna device.

[0060] In one embodiment, there are two or more first elastic elements 6, which are spaced apart from each other and surround the outer side of the connection between the extension portion 12 and the top cover 2. This embodiment enables the two or more first elastic elements 6 to be spaced apart from each other and surround the outer side of the antenna device, thereby achieving multi-angle structural protection.

[0061] like Figure 5 As shown, in one embodiment, the first elastic member 6 is provided with a first groove 61 and a second groove 62 with the groove directions opposite to each other, the top cover 2 has a first connecting portion 21 located in the first groove 61, and the outer extension 12 has a first extension portion 121 located in the second groove 62.

[0062] The top cover 2 also has a second connecting portion 22 located inside the first connecting portion 21, and the outer extension 12 also has a second extension portion 122 located inside the first extension portion 121. A snap-fit ​​connection structure 7 is provided between the second connecting portion 22 and the second extension portion 122.

[0063] This embodiment utilizes a double-groove reverse-fitting design to effectively constrain the relative displacement between the top cover 2 and the outer extension 12, and to generate anti-torsional torque under impact scenarios, thereby improving structural stability. Simultaneously, a snap-fit ​​connection structure 7 is provided between the second connecting part 22 and the second extension 122, forming a mechanical lock without the need for additional fasteners, improving assembly efficiency and avoiding the poor sealing defects caused by using fasteners.

[0064] In one embodiment, the snap-fit ​​connection structure 7 includes a claw and a slot. The second connecting part 22 is provided with a claw, and the second extension part 122 is provided with a slot. The claw and the slot are connected to realize the detachable connection between the top cover 2 and the outer extension part 12.

[0065] like Figure 7 and Figure 8 As shown, in one embodiment, a positioning block 621 is provided in the second groove 62, and a positioning groove 1211 is provided on the first extension 121, with the positioning block 621 located in the positioning groove 1211.

[0066] In this embodiment, the positioning block 621 and the positioning groove 1211 cooperate to provide assembly guidance for the first elastic member 6, reducing assembly difficulty. Furthermore, the positioning block 621 and the positioning groove 1211 cooperate to limit the position of the first elastic member 6, preventing it from dislodging from its preset position when the antenna device is subjected to external impact.

[0067] like Figure 1 and Figure 3 As shown, in one embodiment, the top cover 2 protrudes away from the base 1 to form an outwardly convex arc-shaped top cover 2. This embodiment disperses and transmits external impact stress along the curvature direction by setting the arc-shaped top cover 2, significantly improving drop resistance and deformation resistance. Simultaneously, the outwardly convex arc-shaped top cover 2 creates a self-cleaning effect, preventing rainwater and dust accumulation from affecting signal transmission. Furthermore, the outwardly convex arc-shaped top cover 2 creates a gradient in the distance between the radiating array and the top cover 2, which helps improve antenna efficiency while reducing back lobe radiation.

[0068] like Figure 3 As shown, in one embodiment, the top cover 2 includes a first connecting portion 21 and an arc-shaped portion 23. The top cover 2 is connected to the extension portion 12 through the first connecting portion 21. The arc-shaped portion 23 protrudes to the side away from the base 1. A rounded corner structure 24 is provided at the connection between the first connecting portion 21 and the arc-shaped portion 23.

[0069] In this embodiment, a rounded corner structure 24 is provided at the connection between the first connecting part 21 and the arc-shaped part 23 to eliminate the stress concentration effect in the right-angle transition area and reduce the local stress concentration coefficient. Furthermore, the rounded corner transition smooths the electromagnetic wave reflection path, reduces the radome transmission loss, and reduces harmonic interference.

[0070] like Figure 7 As shown, in one embodiment, a second elastic element 8 is provided at the bottom of the main body 11, and the main body 11 contacts the support surface through the second elastic element 8. This application provides a second elastic element 8 at the bottom of the main body 11 of the antenna device, which effectively absorbs the vibration energy transmitted by the support surface through elastic deformation, reducing the impact of external impacts on internal precision components.

[0071] Specifically, the second elastic element 8 is a cushioning pad, but it is not limited to this.

[0072] like Figures 1 to 8 As shown, in one embodiment, the base 1 is made of a metallic material. This application improves the vibration damping performance of the base 1.

[0073] like Figures 1 to 8 As shown, in one embodiment, the top cover 2 is made of at least one of PC and PBT materials. This application makes the top cover 2 highly weather-resistant, especially suitable for outdoor scenarios.

[0074] like Figures 1 to 8 As shown, this application also provides a communication terminal, including the antenna device as described in any of the embodiments above.

[0075] The antenna device for the communication terminal provided in this application effectively covers the antenna connector through the extension portion 12 when the antenna connector is connected to the antenna interface 5, preventing direct collision between the antenna connector and external objects. This reduces the risk of connector detachment or damage due to collisions, ensuring the antenna device can continuously and stably receive and transmit signals, thus improving the reliability of the antenna device. Furthermore, it significantly reduces the lateral spatial redundancy of the antenna device, decreasing the ineffective volume ratio caused by structural gaps, which helps ensure the miniaturization and lightweighting of the antenna device, and results in a harmonious overall proportion and high aesthetic appeal.
