DETAILED DESCRIPTION

[0039] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the utility model belong to the scope of protection of the utility model.

[0040] With the popularization of 5G technology and the advent of the Internet of Things era, navigation positioning systems will be integrated with more industries to form more application scenarios. For example, in the field of intelligent transportation, navigation positioning systems can be combined with automatic driving technology to achieve accurate vehicle positioning and path planning, and improve road transportation efficiency.

[0041] The navigation positioning system includes an antenna module and a control terminal. The antenna module transmits or receives electromagnetic waves to realize signal transmission. The control terminal converts and processes signals to realize vehicle positioning and path planning. During assembly, such as when the navigation positioning system is installed on a vehicle, the antenna module and the control terminal need to be connected to the vehicle respectively, which requires two assembly processes, resulting in low assembly efficiency.

[0042] Therefore, the utility model embodiment provides an antenna structure, a navigation positioning system and a vehicle. A first shielding is arranged in the hollow shell of the antenna structure, so that the first shielding divides the inner cavity of the shell into a sealed first closed cavity and a sealed second closed cavity. The antenna module is arranged in the first closed cavity, and the control module is arranged in the second closed cavity. The shell wall corresponding to the second closed cavity of the shell is a shielding shell wall, and the shell is grounded. Therefore, during assembly, such as when the antenna structure is installed on a vehicle, the shell integrated with the antenna module and the control module is directly connected to the vehicle, which realizes the assembly of the antenna structure, saves the installation process, and improves the assembly efficiency. To some extent, the occupied space on the vehicle is also saved.

[0043] The antenna structure, the navigation positioning system and the equipment provided by the utility model will be described in detail below with reference to the drawings and specific embodiments:

[0044] Reference Figures 1 to 4As shown, the embodiment provides an antenna structure, which comprises a shell 1, an antenna module 2, a control module 3 and a first shielding member 4.

[0045] Specifically, referring to Figure 1 and Figure 2 As shown, the first shielding member 4 is arranged in the shell 1 and is sealingly arranged with the inner wall of the shell 1. The first shielding member 4 divides the inner cavity of the shell 1 into a first sealed cavity and a second sealed cavity. The antenna module 2 is arranged in the first sealed cavity, and the control module 3 is arranged in the second sealed cavity. The antenna module 2 is electrically connected with the control module 3. The shell wall of the shell 1 corresponding to the second sealed cavity is a shielding shell wall, and the shell 1 is grounded.

[0046] By arranging the first shielding member 4 in the shell 1, the first shielding member 4 divides the inner cavity of the shell 1 into a first sealed cavity and a second sealed cavity, and the first shielding member 4 has good electromagnetic shielding performance. The antenna module 2 is arranged in the first sealed cavity, and the control module 3 is arranged in the second sealed cavity. That is, the antenna module 2 and the control module 3 are arranged in the sealed cavities on the two sides of the first shielding member 4, respectively, and the antenna module 2 and the control module 3 are electrically connected. In this way, the antenna module 2, the first shielding member 4 and the control module 3 are stacked in the shell 1, and the antenna module 2 and the control module 3 are integrated in the shell 1. Therefore, when assembling, the shell 1 only needs to be installed on the vehicle, and the assembly of the antenna structure can be realized. This simplifies the assembly process, improves the assembly efficiency, and saves the occupied space on the vehicle to some extent, which is convenient for assembly.

[0047] Moreover, by separating the antenna module 2 and the control module 3 through the first shielding member 4, the control module 3 does not interfere with the antenna module 2, and the stable working performance of the antenna module 2 is ensured.

[0048] In addition, by making the shell wall of the shell 1 corresponding to the second sealed cavity a shielding shell wall, that is, the shell 1 on the side of the first shielding member 4 facing the control module 3 is a shielding shell, the shell wall of the second sealed cavity where the control module 3 is located is arranged as a shielding shell wall, and the shell 1 is grounded. In this way, the first shielding member 4 and the shielding shell jointly define the second sealed cavity. The second sealed cavity has good shielding and isolation effect on the basis of having sealing property. Since the control module 3 is located in the second sealed cavity, the second sealed cavity has better shielding and isolation effect on the control module 3, which further avoids the situation that the control module 3 interferes with the antenna module 2, thereby further ensuring the stable working performance of the antenna module 2.

[0049] In some embodiments, the region of the shell 1 corresponding to the second sealed cavity can be a metal shell, which can effectively shield electromagnetic wave signals, so that the isolation and shielding effect of the second sealed cavity is good, thereby better isolating the control module 3 and further avoiding interference with the antenna module 2.

[0050] The first shielding member 4 is sealingly arranged with the inner wall of the shell 1, and specifically, the circumferential side wall of the first shielding member 4 can be attached to the inner wall of the shell 1 to achieve sealing. For example, a sealing ring, sealing glue or the like can be arranged between the circumferential side wall of the first shielding member 4 and the inner wall of the shell 1, and the circumferential side wall of the first shielding member 4 and the outer wall of the shell 1 are sealingly arranged through the sealing ring, sealing glue or the like.

[0051] Of course, in another implementation, a sealing groove can be formed on the inner wall of the shell 1, the sealing groove is arranged along the circumference of the shell 1, and the circumferential outer edge of the first shielding member 4 extends into the sealing groove and abuts against the groove wall of the sealing groove.

[0052] Specifically, the shape of the first shielding member 4 can match the cross-sectional shape of the inner cavity of the shell 1, so that the first shielding member 4 is better attached and sealed with the inner wall of the shell 1.

[0053] For example, the inner cavity of the shell 1 is a rectangular cuboid, and the first shielding member 4 can be a rectangular shielding plate.

[0054] In some embodiments, the first shielding member 4 is a metal shielding member, such as an aluminum alloy, steel or the like, which can effectively shield electromagnetic wave signals and ensure the communication quality of the antenna module 2, thereby improving the communication quality of the antenna structure of the embodiment.

[0055] In some implementations, the antenna module 2 and the control module 3 can be electrically connected in a wireless connection manner.

[0056] In another implementation, the antenna module 2 and the control module 3 can be electrically connected in a wire harness connection manner, for example, a first avoiding hole (not shown) for the wire harness to pass through can be formed on the first shielding member 4, and the outer wall of the connecting wire and the hole wall of the first avoiding hole are sealingly and insulatingly arranged.

[0057] The antenna structure provided by the embodiment comprises a hollow shell 1, a first shielding member 4 is arranged in the shell 1, and the first shielding member 4 divides the inner cavity of the shell 1 into a first closed cavity and a second closed cavity. The antenna module 2 is arranged in the first closed cavity, and the control module 3 is arranged in the second closed cavity. The antenna module 2 and the control module 3 are electrically connected, the shell 1 is grounded, and the shell wall of the shell 1 corresponding to the second closed cavity is a shielding shell wall. When the antenna structure is mounted on a vehicle, for example, the shell 1 integrated with the antenna module 2 and the control module 3 is directly connected to the vehicle, thereby realizing the assembly of the antenna structure, and the antenna module 2 and the control module 3 are installed at one time. Compared with the prior art, the installation process is saved, and the assembly efficiency is improved. The occupied space is also saved to a certain extent.

[0058] Meanwhile, since the antenna module 2 and the control module 3 are integrated in one shell 1, in order to prevent the control module 3 from interfering with the antenna module 2, the first shielding member 4 is used to separate the antenna module 2 and the control module 3, the shell wall of the second closed cavity where the control module 3 is arranged is set as a shielding shell wall, and the shell 1 is grounded. In this way, the second closed cavity defined by the first shielding member 4 and the shielding shell wall of the shell 1 can isolate the control module 3, avoid the interference of the control module 3 on the antenna module 2, and ensure the stable working performance of the antenna module 2.

[0059] In addition, since the antenna module 2 and the control module 3 are integrated in one shell 1, the antenna structure provided by the embodiment integrates the control function on the basis of the antenna function, realizes the diversification of functions, and meets the use requirements of users.

[0060] Reference Figure 1 and Figure 2 As shown in FIGS. 1, 2, 3 and 4, in some embodiments, the control module 3 comprises a baseband board 31 and a control device (not shown), the control device is connected with the baseband board 31, and the baseband board 31 is connected with the shell 1.

[0061] The control device is connected to the baseband board 31, and the baseband board 31 is connected in the shell 1. In this way, the assembly of the control module 3 in the shell 1 can be realized through the connection of the baseband board 31 and the shell 1, which is convenient and stable.

[0062] Specifically, the baseband board 31 can be connected to the part of the shell 1 corresponding to the second closed cavity.

[0063] The control device can be a microcontroller unit (MCU), an inertial measurement unit (IMU), a global navigation satellite system (GNSS), a controller area network (CAN), an Ethernet, a power supply chip, a power supply detection chip, etc.

[0064] In addition, the baseband board 31 is usually provided with a grounding structure, which is mainly used to provide a stable current return path, reduce electromagnetic interference, ensure stable signal transmission, and thus provide grounding protection for the control module 3.

[0065] In some embodiments, the side wall of the baseband board 31 is in contact with the inner wall of the shell 1.

[0066] Since the shell 1 is grounded, the grounding effect of the baseband board 31 is enhanced by directly grounding the side wall of the baseband board 31 to the inner wall of the shell 1.

[0067] Since the baseband board 31 is located in the second sealed cavity, and the shell wall corresponding to the second sealed cavity of the shell 1 is a shielding shell, the side wall of the baseband board 31 can be in contact with the shell wall corresponding to the second sealed cavity, which further enhances the grounding of the control module 3, makes the grounding of the control module 3 more sufficient, and has better grounding performance, which can effectively eliminate power frequency interference and avoid interference to the control module 3, further grounding protection for the control module 3, and helps to prolong the service life of the control module 3.

[0068] At the same time, the shielding effect of the second sealed cavity on the control module 3 is improved, further avoiding interference of the control module 3 to the antenna module 2, and further ensuring the stable working performance of the antenna module 2.

[0069] In some embodiments, a first conductive member (not shown) is arranged between the side wall of the baseband board 31 and the inner wall of the shell 1.

[0070] By arranging the first conductive member between the side wall of the baseband board 31 and the inner wall of the shell 1, since the first conductive member has the property of conducting electricity, the first conductive member acts as a capacitor between the grounding structure of the baseband board 31 and the shell 1, further improving the grounding performance of the baseband board 31, which can isolate low-frequency high-voltage static electricity, suppress high-frequency interference, avoid high-frequency signal radiation, protect the circuit of the control module 3, and make the service life of the control module 3 longer.

[0071] Meanwhile, the shielding effect of the second sub-shell 12 on the control module 3 is further improved, so that the control module 3 is further prevented from interfering with the antenna module 2, and the stable working performance of the antenna module 2 is ensured.

[0072] In some implementations, the first conductive member can be, for example, a conductive glue.

[0073] In some embodiments, the control member is arranged on the side of the baseband board 31 away from the first shielding member 4 and is in contact with the inner wall of the shell 1. The control member is in heat-conducting contact with the inner wall of the shell 1, so that the working heat of the control member can be transferred to the shell 1 for heat dissipation. The heat dissipation performance is good, and the working performance of the control member is ensured.

[0074] Reference Figure 1 and Figure 2 As shown in FIGS. 1, 2, and 3, in some embodiments, the antenna module 2 includes a radio frequency board 21 and an antenna body 22. The radio frequency board 21 is connected with the shell 1, and the antenna body 22 is arranged on the side of the radio frequency board 21 away from the first shielding member 4. The antenna body 22, the radio frequency board 21, and the first shielding member 4 are arranged in layers in the shell 1. The antenna body 22 is electrically connected with the control module 3. The layout is reasonable, and the communication performance of the antenna body 22 is good.

[0075] The radio frequency board 21 is usually provided with a grounding structure. The grounding structure is mainly used to provide a stable current return path, reduce electromagnetic interference, and ensure stable transmission of signals, thereby grounding protection for the radio frequency module.

[0076] In specific implementation, the radio frequency board 21 is provided with, for example, a global navigation satellite system (GNSS). The antenna body 22 can be electrically connected with the control module 3 through the GNSS.

[0077] In some implementations, the antenna body 22 can be, for example, an antenna ceramic sheet.

[0078] In some implementations, the antenna body 22 can be directly connected on the side of the radio frequency board 21 away from the first shielding member 4. In this way, the radio frequency board 21 is connected in the first closed cavity of the shell 1. Through the connection of the radio frequency board 21 and the shell 1, the assembly of the antenna module 2 in the shell 1 is realized. The assembly is convenient and stable.

[0079] For example, the antenna body 22 can be welded on the radio frequency board 21.

[0080] In other implementations, the antenna body 22 can be connected on the inner wall of the shell 1 through a support or the like.

[0081] In some embodiments, the side wall of the radio frequency board 21 is in contact with the inner wall of the shell 1.

[0082] By making the side wall of the radio frequency board 21 in contact with the inner wall of the shell 1, direct grounding is achieved, which further enhances the grounding effect of the radio frequency board 21, makes the grounding of the antenna module 2 more sufficient, and has better grounding performance, can effectively eliminate power frequency interference, avoid interference to the antenna module 2, and achieve further grounding protection for the antenna module 2, to a certain extent, avoid the antenna module 2 from being affected by lightning and other weather and environmental factors, and help to prolong the service life of the antenna module 2.

[0083] At the same time, the anti-interference performance of the antenna module 2 is enhanced, and the communication quality of the antenna module 2 is ensured.

[0084] In some embodiments, a second conductive member (not shown) is arranged between the side wall of the radio frequency board 21 and the inner wall of the shell 1.

[0085] By arranging the second conductive member between the side wall of the radio frequency board 21 and the inner wall of the shell 1, since the second conductive member has a conductive property, the second conductive member forms a path between the grounding circuit of the radio frequency board 21 and the shell 1, acts as a capacitor, further improves the grounding performance of the radio frequency board 21, can isolate low-frequency high-voltage static electricity, suppress high-frequency interference, avoid high-frequency signal radiation, protect the circuit of the antenna module 2, and make the service life of the antenna module 2 higher.

[0086] At the same time, the anti-interference performance of the antenna module 2 is further enhanced, thereby further ensuring the stable communication quality of the antenna module 2.

[0087] In some implementations, the second conductive member can be, for example, conductive glue.

[0088] In some embodiments, the side of the radio frequency board 21 facing the first shielding member 4 is provided with a radio frequency device, and the antenna structure further comprises a second shielding member 5 connected between the radio frequency board 21 and the first shielding member 4 and covering the outside of the radio frequency device.

[0089] By arranging the radio frequency device on the side of the radio frequency board 21 facing the first shielding member 4, the radio frequency device and the antenna body 22 are arranged on the two sides of the radio frequency board 21, and the first shielding member 4 also has good shielding performance for the radio frequency device, avoiding interference of the radio frequency device to the antenna body 22, and improving the anti-interference performance of the antenna module 2 itself.

[0090] By arranging the second shielding member 5 between the radio frequency board 21 and the first shielding member 4, specifically, the two sides of the second shielding member 5 can be connected with the radio frequency board 21 and the first shielding member 4 respectively, so that the second shielding member 5 and the first shielding member 4 jointly form a shielding cavity. Since the second shielding member 5 is arranged on the circumferential outer side of the radio frequency device, the radio frequency device is located in the shielding cavity, so that the second shielding member 5 has an isolation shielding effect on the radio frequency device under the shielding effect of the first shielding member 4, further avoiding the interference of the radio frequency device on the antenna body 22, thereby further improving the anti-interference performance of the antenna module 2 itself.

[0091] In some implementations, the second shielding member 5 can be connected to the side of the first shielding member 4 facing the radio frequency board 21, and when the first shielding member 4 and the radio frequency board 21 are connected in place in the shell 1, the second shielding member 5 is in contact with the radio frequency board 21.

[0092] In other implementations, the second shielding member 5 can be connected to the side of the radio frequency board 21 facing the first shielding member 4, and when the first shielding member 4 and the radio frequency board 21 are connected in place in the shell 1, the second shielding member 5 is in contact with the first shielding member 4.

[0093] In specific implementations, the second shielding member 5 is a metal shielding member, such as aluminum alloy, steel, etc., which can effectively shield electromagnetic wave signals and ensure the communication quality of the antenna module 2, thereby improving the communication quality of the antenna structure of the embodiment.

[0094] The radio frequency device can be, for example, a global navigation satellite system (GNSS), a power supply chip, etc.

[0095] In some embodiments, the side of the radio frequency board 21 facing the first shielding member 4 is provided with a heat dissipation member (not shown), which is in thermal conductive connection with the radio frequency device and the shell 1 respectively, so that the working heat of the radio frequency device can be transferred to the shell 1 through the heat dissipation member for heat dissipation, and the heat dissipation performance is good, thereby ensuring the stable working performance of the radio frequency device and the antenna structure.

[0096] In some implementations, the side of the heat dissipation member away from the radio frequency device can be directly connected with the inner wall of the shell 1.

[0097] In other implementations, the side of the heat dissipation member away from the radio frequency device can be connected with at least one of the second shielding member 5 and the first shielding member 4, so that the working heat of the radio frequency device can be dissipated through at least one of the second shielding member 5 and the first shielding member 4, facilitating the arrangement and connection of the heat dissipation member.

[0098] In a specific implementation, the heat dissipation member can be a heat dissipation glue.

[0099] Referring to Figures 1 to 4 As shown in the drawings, in some embodiments, the shell 1 includes a first sub-shell 11 and a second sub-shell 12 connected together. The shell wall of the second sub-shell 12 is a shielding shell wall, the first shielding member 4 is arranged in the second sub-shell 12, and the side of the first shielding member 4 away from the first sub-shell 11 and the second sub-shell 12 together enclose a second closed cavity. The antenna module 2 is arranged in the first sub-shell 11 and is detachably connected to the second sub-shell 12 through a fastener.

[0100] By arranging the shell 1 as the first sub-shell 11 and the second sub-shell 12 and arranging the second sub-shell 12 as a shielding shell, the manufacturing and assembly are facilitated.

[0101] The first shielding member 4 is arranged in the second sub-shell 12, and the first shielding member 4 is sealingly arranged with the inner wall of the second sub-shell 12. In this way, the side of the first shielding member 4 away from the first sub-shell 11 and the second sub-shell 12 together enclose a sealed second closed cavity, and the cavity wall of the second closed cavity has good shielding isolation performance.

[0102] The control module 3 is arranged on the side of the first shielding member 4 away from the first sub-shell 11. Since the side of the first shielding member 4 away from the first sub-shell 11 and the second sub-shell 12 together enclose a second closed cavity, the control module 3 is located in the second closed cavity enclosed by the first shielding member 4 and the second sub-shell 12. Therefore, the first shielding member 4 and the second sub-shell 12 have good shielding isolation effect on the control module 3, so that the control module 3 does not interfere with the antenna module 2.

[0103] The antenna module 2 is arranged in the first sub-shell 11, and the antenna module 2 is connected to the second sub-shell 12, facilitating the assembly of the antenna module 2.

[0104] In a specific implementation, referring to Figure 1 and Figure 2 As shown in the drawings, the second sub-shell 12 has a concave cavity recessed in the direction away from the first sub-shell 11. In the direction along the second sub-shell 12 to the first sub-shell 11, the first shielding member 4 and the control module 3 are stacked and arranged in the concave cavity. The antenna module 2 is arranged on the opening of the concave cavity of the second sub-shell 12 and is connected to the second sub-shell 12, facilitating the assembly.

[0105] Meanwhile, since the radio frequency (RF) devices on the RF board 21 of the antenna module 2 are typically located on the side of the RF board 21 facing the first shielding member 4, when the antenna module 2 is covered at the opening of the cavity in the second sub-shell 12, at least a portion of the RF devices can be located within the space formed by the second sub-shell 12 and the first shielding member 4 facing the first sub-shell 11. Because the second sub-shell 12 is a shielding shell, and the first shielding member 4 has excellent shielding performance, the second sub-shell 12 and the first shielding member 4 provide both isolation and shielding for the control module 3 and good shielding for the RF devices. This further prevents the RF devices from interfering with the antenna body 22 of the antenna module 2, further ensuring the working performance of the antenna body 22. Based on this, the second sub-shell 12, as a shielding shell, can simultaneously provide good shielding and isolation for both the control module 3 and the RF devices on the RF board 21, giving the antenna structure better communication performance.

[0106] In some implementations, refer to Figure 1 As shown, for example, a first mounting hole can be provided on the second sub-shell 12, or a second mounting hole (not shown) can be provided on the vehicle body.
