Description

Technical Field

[0001] This application relates to the field of vehicle antenna technology, and more particularly to an instrument panel assembly and a vehicle. Background Technology

[0002] With the increasing popularity of intelligent connected vehicles, the demand for wireless signals such as communication and navigation is rising sharply. To meet this demand, various functional antennas are integrated into the vehicle, such as satellite positioning antennas, cellular communication antennas, Bluetooth antennas, and radio frequency antennas. To simplify the installation process and save space, existing technologies typically integrate these multiple antennas onto a single circuit board to form an integrated antenna module, which is then installed inside the vehicle.

[0003] However, the vehicle's metal casing has an electromagnetic shielding effect. When existing antenna modules are installed in vehicles, the vehicle casing attenuates or shields the signal when the antenna with higher signal requirements (such as satellite antennas) is close to or facing the vehicle's metal casing, resulting in decreased positioning accuracy or signal loss, which affects the accuracy of the antenna module during use.

[0040] To better understand the above-mentioned objectives, features, and advantages of this application, the solution of this application will be further described below. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0041] Many specific details are set forth in the following description in order to provide a full understanding of this application, but this application may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only some embodiments of this application, and not all embodiments.

[0042] Reference Figures 1 to 6 As shown, the first aspect of this application provides an instrument panel assembly installed inside a vehicle housing, including: an instrument panel body 1, having a first mating part 11 and a second mating part 12; an antenna module 2, including a housing 20, a substrate 3, a satellite antenna 31, and an antenna group; the housing 20 is fixed to the instrument panel body 1, with a first end 21 and a second end 22 at its two ends along its length, the substrate 3 is fixedly installed inside the housing 20, the satellite antenna 31 is disposed at the end of the substrate 3 near the first end 21, and the antenna group is disposed on the substrate 3 and spaced apart from the satellite antenna 31; the outer side of the housing 20 has a first positioning part 23 and a second positioning part 24; when the housing 20 is fixed to the instrument panel body 1, the first positioning part 23 is in a limiting fit with the first mating part 11, and the second positioning part 24 is in a limiting fit with the second mating part 12, so that the first end 21 is located on the side near the vehicle's central axis relative to the second end 22.

[0043] Specifically, the instrument panel body 1 is installed inside the vehicle housing and is located near the front of the vehicle. The outer shell 20 can be connected to the instrument panel body 1 by bolts, or the outer shell 20 can be connected to the instrument panel body 1 by rivets. Alternatively, the outer shell 20 has a buckle on its outside and the instrument panel body 1 has a slot. The buckle and the slot are engaged to make the outer shell 20 and the instrument panel body 1 engage.

[0044] The housing 20 has an internal installation space, within which the substrate 3, satellite antenna 31, and antenna assembly are all housed. The satellite antenna 31 and antenna assembly are fixed to the substrate 3, which is bolted to the inner wall of the housing 20. Optionally, the housing 20 may include an upper shell 201 and a bottom plate 202, with the upper shell 201 and bottom plate 202 facing each other. The side of the upper shell 201 facing the bottom plate 202 is recessed to form a receiving groove. The substrate 3 is mounted on the side of the bottom plate 202 facing the upper shell 201. After the bottom plate 202 is connected to the upper shell 201, it blocks the opening of the receiving groove, allowing the substrate 3 to be located within the receiving groove.

[0045] The vehicle's centerline extends along the length of the vehicle and is located at the center of the vehicle's width. The satellite antenna can be a rectangular block structure and can be soldered to a portion of the substrate 3 near the first end, so that after the housing 20 is mounted on the instrument panel body 1, the satellite antenna is positioned near the vehicle's centerline; the satellite antenna is positioned away from the vehicle housing, so that the satellite antenna is located at the vehicle's windshield, reducing the shielding effect of the vehicle housing.

[0046] The antenna array described above can include various types of antennas, such as cellular antennas, wireless antennas, Bluetooth antennas, and radio frequency antennas. These antennas are located in the middle of the substrate 3 or near the second end 22 of the substrate 3 to avoid mutual interference between the various antennas and the satellite antenna.

[0047] The first positioning part 23 and the second positioning part 24 can both be cylindrical structures, and the first mating part 11 and the second mating part 12 can both be grooves. The shapes of the first positioning part 23 and the second positioning part 24 can be different, so that the first positioning part 23 can only be inserted into the first mating part 11. For example, the cross-sectional shape of the first positioning part 23 is triangular, and the groove of the first mating part 11 is triangular and matches the size of the first positioning part 23; the cross-sectional shape of the second positioning part 24 is square, and the groove of the second mating part 12 is rectangular and matches the size of the first positioning part 23, and the size of the first positioning part 23 is larger than the size of the second positioning part 24. When the first positioning part 23 is inserted into the first mating part 11, and the second positioning part 24 is inserted into the second mating part 12, the outer casing 20 can be installed on the instrument panel body 1. When the outer casing 20 rotates 180°, the shapes of the grooves of the second positioning part 24 and the first mating part 11 do not match, and the shapes of the grooves of the first positioning part 23 and the second mating part 12 do not match, at which point the outer casing 20 cannot be installed on the instrument panel body 1. This achieves the effect of determining the orientation of the outer casing 20 on the instrument panel body 1.

[0048] Alternatively, the number of the first positioning part 23 and the second positioning part 24 can be different. For example, the first positioning part 23 may include multiple pillars, and the second positioning part 24 may include at least one pillar. The number of pillars in the first positioning part 23 may be greater than the number of pillars in the second positioning part 24. The number of grooves in the first mating part 11 may be equal to the number of pillars in the first positioning part 23, and the number of grooves in the second mating part 12 may be equal to the number of pillars in the second positioning part 24. The first positioning part 23 is inserted into the first mating part 11. When the housing 20 rotates 180°, the number of slots in the second positioning part 24 and the first mating part 11 may not match, and the number of slots in the first positioning part 23 and the second mating part 12 may not match. At this time, the housing 20 cannot be installed on the instrument panel body 1. The first positioning part 23 can only be inserted into the first mating part 11, and the second positioning part 24 can only be inserted into the second mating part 12, thus achieving the effect of determining the orientation of the housing 20 on the instrument panel body 1.

[0049] Alternatively, it may not be limited to the first positioning part 23 and the second positioning part 24 being inclined plates, and the first positioning part 23 and the second positioning part 24 having a non-centrally symmetrical structure, that is, taking the midpoint of the line connecting the first positioning part 23 and the second positioning part 24 as the symmetry point, the first positioning part 23 will not coincide with the second positioning part 24 after rotating 180° about the symmetry point; when the outer shell 20 is in the correct position, the first positioning part 23 is inserted into the first mating part 11, and the second positioning part 24 is inserted into the second mating part 12. When the outer shell 20 is rotated 180°, the angles of the grooves of the second positioning part 24 and the first mating part 11 do not match, the angles of the grooves of the first positioning part 23 and the second mating part 12 do not match, and the angles of the grooves of the first positioning part 23 and the second mating part 12 do not match. At this time, the outer shell 20 cannot be installed on the instrument panel body 1. By ensuring that the first positioning part 23 can only be inserted into the first mating part 11 and the second positioning part 24 can only be inserted into the second mating part 12, the orientation of the outer shell 20 on the instrument panel body 1 is determined.

[0050] When the first positioning part 23 and the second positioning part 24 are in a centrally symmetrical position, at least one of the following—the number, shape, and size of the first positioning part 23 and the second positioning part 24—can be unequal, so that the first positioning part 23 can only be inserted into the first mating part 11, and the second positioning part 24 can only be inserted into the second mating part 12. When the positions and shapes of the first positioning part 23 and the second positioning part 24 are not centrally symmetrical, after the outer casing 20 is rotated 180° from the correct position, the first positioning part 23 cannot be inserted into the second mating part 12, and the second positioning part 24 cannot be inserted into the first mating part 11.

[0051] The first positioning part 23 and the second positioning part 24 mentioned above can also be selected as a groove structure. The first mating part 11 and the second mating part 12 are column structures protruding on the instrument panel body 1, so that the first mating part 11 can be inserted and connected with the first positioning part 23, and the second mating part 12 can be inserted and connected with the second positioning part 24.

[0052] The first positioning part 23 and the second positioning part 24 can be arranged at intervals along the length direction of the outer casing 20, or they can be arranged at intervals along the width direction of the outer casing 20. As long as the first positioning part 23 is limited to the first mating part 11 and the second positioning part 24 is limited to the second mating part 12, the first end 21 can be positioned on the side of the second end 22 near the centerline of the vehicle when the outer casing 20 is on the instrument panel body 1.

[0053] The orientation of the first end 21 and the second end 22 of the aforementioned housing 20 on the instrument panel body 1 is the installation posture of the housing 20. Since the first positioning part 23 engages with the first mating part 11 and the second positioning part 24 engages with the second mating part 12, it ensures that the first end 21 is on the side away from the second end 22 from the vehicle housing, so that the first end 21 is in the middle position near the windshield.

[0054] The instrument panel assembly provided in this application embodiment has a base plate 3 fixed inside a housing 20. A satellite antenna 31 and an antenna group are mounted on the base plate 3. The satellite antenna 31 is located on the base plate 3 near the first end 21. The housing 20 is attached to the instrument panel body 1. The first positioning part 23 is engaged with the first mating part 11, and the second positioning part 24 is engaged with the second mating part 12, so that the first end 21 is located on the side of the second end 22 near the central axis of the vehicle. This allows the satellite antenna at the first end 21 to transmit and receive signals through the windshield of the vehicle, reducing the shielding effect of the vehicle housing on the satellite antenna. After determining the installation position and installation direction of the housing 20, the housing 20 is fixedly connected to the instrument panel body 1.

[0055] The instrument panel assembly provided in this application embodiment has a base plate 3 disposed inside the housing 20. A satellite antenna 31 and an antenna group are mounted on the base plate 3. The satellite antenna 31 is disposed at one end of the base plate 3 near the first end 21 of the housing 20. The first positioning part 23 on the housing 20 corresponds to the first mating part 11 on the instrument panel body 1, and the second positioning part 24 on the housing 20 corresponds to the second mating part 12 on the instrument panel body 1, thereby constraining the orientation of the housing 20 on the instrument panel body 1. This ensures that the first end 21 is on the side of the second end 22 near the central axis of the vehicle, so that the satellite antenna 31 is away from the vehicle housing, reducing the shielding effect of the vehicle housing on the satellite antenna 31 and improving the accuracy of the antenna module during use.

[0056] Reference Figures 3 to 5 As shown, in some embodiments, the first positioning part 23 is located at the first end 21, and the second positioning part 24 is located at the second end 22; the first positioning part 23 and the second positioning part 24 have a non-centrally symmetrical structure.

[0057] With this configuration, the first positioning part 23 and the second positioning part 24 can fully utilize the space along the length of the outer casing 20. When the first positioning part 23 and the second positioning part 24 are machined on the outer casing 20, mutual interference caused by the first positioning part 23 and the second positioning part 24 being too close can be avoided. The operator can easily mate the first positioning part 23 and the second positioning part 24 with the first mating part 11 and the second mating part 12 by holding the first end 21 and the second end 22 with both hands and moving the outer casing 20.

[0058] Specifically, the first positioning part 23 and the second positioning part 24 are spaced apart along the length of the outer shell 20. The first positioning part 23 is located at the first end 21, and the second positioning part 24 is located at the second end 22. The first positioning part 23 is limited to the first mating part 11, and the second positioning part 24 is limited to the second mating part 12, so that the first end 21 is in a position opposite to the first positioning part 23, and the satellite antenna 31 is located near the central axis of the vehicle.

[0059] The first positioning part 23 and the second positioning part 24 may have different shapes and tilt angles. When the first positioning part 23 is engaged with the first mating part 11 and the second positioning part 24 is engaged with the second mating part 12, the housing 20 is in a first posture, at which time the first end 21 is on the side of the second end 22 close to the central axis of the vehicle. When the housing 20 is rotated 180° from the first posture to exchange the positions of the first positioning part 23 and the second positioning part 24 to reach the second posture, the first positioning part 23 cannot be engaged with the second mating part 12 and the second positioning part 24 cannot be engaged with the first mating part 11, so that the housing 20 cannot be installed on the instrument panel body 1.

[0060] Reference Figures 3 to 5 As shown, in some embodiments, at least one of the shape and cross-sectional dimensions of the first positioning portion 23 and the second positioning portion 24 are different.

[0061] With this configuration, the first positioning part 23 and the second positioning part 24 are distinguished from each other by their shape and cross-sectional size, so that the first positioning part 23 can only mate with the first mating part 11 and the second positioning part 24 can only mate with the second mating part 12, ensuring that when the housing 20 is installed on the instrument panel body 1, the first end 21 is located on the side of the second end 22 that is close to the centerline of the vehicle.

[0062] Specifically, the first positioning part 23 can be a cylinder, the second positioning part 24 is a prism, the first mating part 11 is a groove that matches the shape of the cylinder, and the second mating part 12 is a groove that matches the shape of the cylinder, so that the first positioning part 23 cannot be inserted into the second mating part 12, and the second positioning part 24 cannot be inserted into the first mating part 11.

[0063] Alternatively, the dimensions of the cross-section of the first positioning part 23 and the cross-section of the second positioning part 24 can be different, the dimensions of the groove opening of the first mating part 11 can be the same as the dimensions of the cross-section of the first positioning part 23, and the dimensions of the groove opening of the second mating part 12 can be the same as the dimensions of the cross-section of the second positioning part 24.

[0064] The cross-sectional dimension of the first positioning part 23 can be larger than that of the second positioning part 24. When the housing 20 is in the first posture described above, the first positioning part 23 can be inserted into the first mating part 11, and the second positioning part 24 can be inserted into the second mating part 12. When the housing 20 is rotated to the second posture described above, the second positioning part 24 can be inserted into the first mating part 11 because of its smaller size, but the first positioning part 23 is too large to be inserted into the second mating part 12, so the housing 20 cannot be installed on the instrument panel body 1.

[0065] Reference Figures 3 to 5 As shown, in some embodiments, the first positioning part 23 and the second positioning part 24 are both inclined toward the center of the outer casing 20, and the inclination angles of the first positioning part 23 and the second positioning part 24 relative to the center of the outer casing 20 are different.

[0066] With this configuration, the first positioning part 23 and the second positioning part 24 are distinguished from each other by their inclination with respect to the housing 20, so that the first positioning part 23 can only cooperate with the first mating part 11 and the second positioning part 24 can only cooperate with the second mating part 12, ensuring that when the housing 20 is installed on the instrument panel body 1, the first end 21 is on the side of the second end 22 close to the vehicle's central axis.

[0067] Specifically, the plane of the outer casing 20 with the first positioning part 23 and the second positioning part 24 is used as the first reference plane; the first positioning part 23 extends obliquely relative to the first reference plane, and the second positioning part 24 extends obliquely relative to the center of the outer casing 20; the first mating part 11 is obliquely arranged with the first positioning part 23 at the same angle, so that the shape of the first mating part 11 matches that of the first positioning part 23; the second mating part 12 is obliquely arranged with the second positioning part 24 at the same angle, so that the shape of the second mating part 12 matches that of the second positioning part 24; and the first positioning part 23 and the second positioning part 24 have a non-centrally symmetrical structure, so that the outer casing 20 can only be installed on the instrument panel body 1 in the first posture. In the second posture, the inclination of the first positioning part 23 and the second mating part 12 are different, and the inclination of the second positioning part 24 and the second mating part 12 are also different, so the outer casing 20 cannot be installed on the instrument panel body 1.

[0068] Alternatively, both the first positioning part 23 and the second positioning part 24 can be plate structures, and both the first mating part 11 and the second mating part 12 can be groove structures. The first positioning part 23 is inclined relative to the second reference surface, and the second positioning part 24 is also inclined relative to the second reference surface. The groove of the first mating part 11 is adapted to the first positioning part 23, and the groove of the second mating part 12 is adapted to the second positioning part 24. The first positioning part 23 and the second positioning part 24 have a non-centrally symmetrical structure, so that the outer shell 20 can only be installed on the instrument panel body 1 in the first posture. In the second posture, the inclination of the first positioning part 23 and the second mating part 12 are different, and the inclination of the second positioning part 24 and the second mating part 12 are also different. At this time, the outer shell 20 cannot be installed on the instrument panel body 1.

[0069] The first positioning part 23 and the second positioning part 24 mentioned above can be either a columnar structure or an irregular block structure. Both the first positioning part 23 and the second positioning part 24 are inclinedly extended on the outside of the outer shell 20.

[0070] Reference Figures 3 to 5 As shown, in some embodiments, the first positioning part 23 includes at least one first sub-part, the second positioning part 24 includes at least one second sub-part, and the number of first sub-parts is greater than or less than the number of second sub-parts; the first mating part 11 includes at least one first sub-matting part, and the second mating part 12 includes at least one second sub-matting part; each first sub-part is engaged with one first sub-matting part, and each second sub-part is engaged with one second sub-matting part.

[0071] With this configuration, the first positioning part 23 and the second positioning part 24 can be distinguished from each other by the unequal number of the first and second sub-parts. This ensures that the first positioning part 23 can only cooperate with the first mating part 11, and the second positioning part 24 can only cooperate with the second mating part 12. This ensures that when the housing 20 is installed on the instrument panel body 1, the first end 21 is on the side of the second end 22 that is close to the vehicle's central axis.

[0072] Specifically, the number of first sub-parts can be greater than the number of second sub-parts, the number of first sub-mates can be equal to the number of first sub-parts, and the number of second sub-mates can be equal to the number of first sub-parts. This ensures that when the housing 20 is in its first position, multiple first sub-parts mate with multiple first sub-mates, and each second sub-part mates with a corresponding second sub-mate. When the housing 20 is in its second position, the number of first sub-parts does not correspond to the number of second sub-mates, and the number of second sub-parts does not correspond to the number of first sub-mates, preventing the housing 20 from being installed on the instrument panel body 1.

[0073] Of course, it is also possible to choose that the number of first sub-parts is less than the number of second sub-parts, the number of first sub-parts is equal to the number of first sub-parts, the number of second sub-parts is equal to the number of first sub-parts, and when the outer shell 20 is in the first posture, each first sub-part corresponds to one first sub-part and engages with it, and multiple second sub-parts correspond to multiple corresponding second sub-parts.

[0074] You can choose to have two first sub-parts and one second sub-part, or you can choose to have one first sub-part and two second sub-parts.

[0075] Reference Figures 2 to 5 As shown, in some embodiments, the first mating part 11 includes a first groove, and the second mating part 12 includes a second groove; the first positioning part 23 includes a first insert plate, and the second positioning part 24 includes a second insert plate. Both the first insert plate and the second insert plate extend along the housing 20 toward the instrument panel body 1; the first insert plate is inserted into the first groove and abuts against the side wall of the first groove; the second insert plate is inserted into the second groove and abuts against the side wall of the second groove.

[0076] With this configuration, the structure of the insert plate and the groove is simple. When the orientation of the outer shell 20 is determined, the first insert plate can be inserted into the first groove and the second insert plate can be inserted into the second groove by moving the outer shell 20.

[0077] Specifically, the shape of the first groove is adapted to the shape of the first insert plate, and the shape of the second groove is adapted to the shape of the second insert plate; the first insert plate and the second insert plate are non-centrally symmetrical structures, and the shapes or cross-sectional dimensions of the first insert plate and the second insert plate can be different so that the first insert plate cannot be inserted into the second groove or the second insert plate cannot be inserted into the first groove.

[0078] Alternatively, the first insert plate and the second insert plate may be tilted at different angles about the first reference plane, or the first insert plate and the second insert plate may be tilted in different directions about the first reference plane. This would allow the first insert plate to engage with the first groove and the second insert plate to engage with the second groove when the outer shell 20 is in the first posture. When the outer shell 20 is in the second posture, the first insert plate cannot be inserted into the second groove and the second insert plate cannot be inserted into the first groove.

[0079] Alternatively, the first and second insert plates can be tilted at different angles relative to the second reference plane. In the first orientation, the first insert plate engages with the first groove, and the second insert plate engages with the second groove. In the second orientation, neither the first nor the second insert plate can be inserted into the second groove. Specifically, when the first and second insert plates are mirror-symmetrical, the included angles of their respective second reference planes are equal. However, in the second orientation, neither the first nor the second insert plate can be inserted into the second groove. Therefore, in this orientation, the first and second insert plates also ensure that when the housing 20 is mounted on the instrument panel body 1, the first end 21 is positioned closer to the vehicle's centerline than the second end 22.

[0080] Alternatively, the first insert plate can have at least one first sub-plate, and the second insert plate can have at least one second sub-plate, with the number of first and second sub-plates being unequal, thereby distinguishing the first positioning part 23 and the second positioning part 24. The first groove includes at least one first sub-groove, and the second groove includes at least one second sub-groove. The number of first sub-grooves can be equal to the number of first sub-plates, and the number of second sub-grooves can be equal to the number of second sub-plates.

[0081] Reference Figures 3 to 5 As shown, in some embodiments, both the first insert plate and the second insert plate are arc-shaped plates, the first groove is an arc-shaped groove adapted to the first insert plate, and the second groove is an arc-shaped groove adapted to the second insert plate.

[0082] With this configuration, the curved plate has good support, and compared with the straight plate structure, the curved plate has a larger contact area with the curved groove, which improves the stability of the first positioning part 23 and the first mating part 11, and improves the stability of the second positioning part 24 and the second mating part 12.

[0083] Specifically, both the first and second insert plates are arc-shaped plates perpendicular to the first reference plane, and their projections onto the first reference plane are arc-shaped. At least one of the length and radius of the corresponding arc of the first and second insert plates differs to distinguish them. The first groove is positioned opposite the first insert plate, and its corresponding arc and radius are equal to those of the first insert plate; similarly, the second groove is positioned opposite the second insert plate, and its corresponding arc and radius are equal to those of the second insert plate.

[0084] Reference Figures 2 to 5 As shown, in some embodiments, the outer casing 20 has a first horizontal plate 25 formed at the first end 21 and a second horizontal plate 26 formed at the second end 22. The instrument panel body 1 is provided with a first pillar 13 and a second pillar 14. The first pillar 13 is connected to the first horizontal plate 25 and the second pillar 14 is connected to the second horizontal plate 26 so that the outer casing 20 is connected to the instrument panel body 1.

[0085] With this configuration, the first horizontal plate 25 and the second horizontal plate 26 serve as mounting structures at both ends of the outer casing 20, and the first column 13 and the second column 14 serve as mounting structures on the instrument panel body 1. The first column 13 and the second column 14 can absorb vibrations on the instrument panel body 1 by small amplitude vibrations, thereby reducing the vibrations transmitted to the antenna module 2 when the vehicle is in motion.

[0086] Specifically, the first horizontal plate 25 and the second horizontal plate 26 are on the same plane, and the plane containing the first horizontal plate 25 and the second horizontal plate 26 can be selected as the first reference plane. The first positioning part 23 can be disposed on the first horizontal plate 25 or disposed at a distance from the first horizontal plate 25; the second positioning part 24 can be disposed on the second horizontal plate 26 or disposed at a distance from the second horizontal plate 26.

[0087] The first column 13 and the second column 14 are spaced apart. The first column 13 is positioned opposite the first horizontal plate 25, and the second column 14 is positioned opposite the second horizontal plate 26. Optionally, the end of the first column 13 furthest from the instrument panel body 1 has a screw hole, and the first horizontal plate 25 has a through hole. A bolt is threaded through the through hole and connected to the screw hole to connect the first horizontal plate 25 to the first column 13. Similarly, the end of the second column 14 furthest from the instrument panel body 1 has a screw hole, and the second horizontal plate 26 has a through hole. A bolt is threaded through the through hole and connected to the screw hole to connect the second horizontal plate 26 to the second column 14. Alternatively, the first column 13 and the first horizontal plate 25 can be connected to each other by welding, and the second column 14 and the second horizontal plate 26 can also be connected by welding.

[0088] Reference Figures 1 to 5 As shown, in some embodiments, the first positioning part 23 protrudes from the first horizontal plate 25, and the second positioning part 24 protrudes from the second horizontal plate 26; the first mating part 11 is formed on the first column 13, and the second mating part 12 is formed on the second column 14; when the first horizontal plate 25 is connected to the first column 13, the first positioning part 23 engages with the first mating part 11; when the second horizontal plate 26 is connected to the second column 14, the second positioning part 24 engages with the second mating part 12.

[0089] With this configuration, the first column 13 is connected to the first horizontal plate 25, and simultaneously enables the limiting engagement of the first positioning part 23 and the first mating part 11; the second column 14 is connected to the second horizontal plate 26, and simultaneously enables the limiting engagement of the second positioning part 24 and the second mating part 12; the connection point between the first positioning part 23 and the first mating part 11 is close to the connection point between the first column 13 and the first horizontal plate 25, facilitating the limiting engagement operation of the first positioning part 23 and the first mating part 11; the connection point between the second positioning part 24 and the second mating part 12 is close to the connection point between the second column 14 and the second horizontal plate 26, facilitating the limiting engagement operation of the second positioning part 24 and the second mating part 12.

[0090] Specifically, the first positioning part 23 is vertically disposed on the first horizontal plate 25, and the second positioning part 24 is vertically disposed on the second horizontal plate 26; the side of the first column 13 forms the first mating part 11, and the side of the second column 14 forms the second mating part 12.

[0091] The first post 13 may be configured to form multiple grooves along its circumference, with some of the grooves serving as the first mating part 11 and limiting the fit with the first positioning part 23; the second post 14 may be configured to form multiple grooves along its circumference, with some of the grooves serving as the second mating part 12 and limiting the fit with the second positioning part 24; and the first post 13 and the second post 14 may be non-centrally symmetrical structures, such that at least one of the shape, orientation, and size of the groove on the first post 13 serving as the first mating part 11 and the groove on the second post 14 serving as the second mating part 12 is different.

[0092] Reference Figure 5 and Figure 6 As shown, in some embodiments, the antenna group includes a first antenna 32, a second antenna 33, and a third antenna 34;

[0093] The first antenna 32 is disposed at one end of the substrate 3 near the second end 22, and the second antenna 33 and the third antenna 34 are disposed between the first end 21 and the second end 22.

[0094] Specifically, the first antenna 32 can be selected as a radio frequency antenna, such as an RF (Radio Frequency) antenna; the second antenna 33 can be selected as a wireless network antenna, such as a 4G antenna; and the third antenna 34 can be selected as a Bluetooth antenna, such as a BLE (Bluetooth Low Energy) antenna.

[0095] The aforementioned satellite antenna 31 occupies the area of ​​the substrate 3 near the first end 21, the first antenna 32 is away from the satellite antenna 31 at the second end 22, and the second antenna 33 and the third antenna 34 are disposed in the middle of the substrate 3 to have a distance from the satellite antenna 31, so as to avoid mutual interference between the first antenna 32, the second antenna 33 and the third antenna 34 and the satellite antenna 31.

[0096] The first antenna 32, the second antenna 33, and the third antenna 34 are all located at the edge of the substrate 3 along the width direction of the outer casing 20. The area of ​​the substrate 3 where no antenna assembly is located forms the mounting area. Multiple through holes are provided in the mounting area, and multiple bolts are used to pass through the multiple through holes and connect to the inner wall of the outer casing 20. When the outer casing 20 includes an upper casing 201 and a bottom plate 202, the mounting area is connected to the bottom plate 202 by multiple bolts. A shielding box is provided between the bottom plate 202 and the substrate 3. The shielding box is connected to the substrate 3 and is positioned opposite to the satellite antenna 31.

[0097] The substrate 3 extends along the length of the outer shell 20. The first antenna 32, the second antenna 33 and the third antenna 34 can all extend along the length of the outer shell 20. The second antenna 33 includes two wireless network antennas. The wireless network antennas are relatively large. The two wireless network antennas are respectively set on the two edges of the substrate 3 along the width of the outer shell 20.

[0098] The housing 20 has mounting holes, through which a connector 35 passes. One end of the connector 35 is connected to the substrate 3 to electrically connect the connector 35 to the satellite antenna 31 and the antenna array. The other end of the connector 35 is exposed on the outside of the housing 20 for electrical connection to the vehicle's controller. The connector 35 is a multi-functional connector that electrically connects to the satellite antenna 31, the first antenna 32, the second antenna 33, and the third antenna 34.

[0099] A second aspect of this application provides a vehicle including an instrument panel assembly as described above.

[0100] Using the aforementioned dashboard assembly in a vehicle ensures that the satellite antenna 31 is positioned close to the vehicle's centerline, reducing interference from the vehicle housing to the satellite antenna 31.

[0101] In the specific use of the instrument panel assembly provided in this application embodiment and in the vehicle, the satellite antenna 31, the first antenna 32, the second antenna 33, and the third antenna 34 are mounted on the base plate 3. The mounting area of ​​the base plate 3 is connected to the base plate 202 by multiple fasteners, and the upper shell 201 is connected to the base plate 202. The outer shell 20 is moved toward the instrument panel body 1, and the first horizontal plate 25 abuts against the end face of the first pillar 13 away from the instrument panel body 1, so that the first insert plate is inserted into the first groove; the second horizontal plate 26 abuts against the end face of the second pillar 14 away from the instrument panel body 1, so that the second insert plate is inserted into the second groove. Then, the first horizontal plate 25 and the first pillar 13 are connected by bolts, and the second horizontal plate 26 and the second pillar 14 are connected by bolts, so that the outer shell 20 is mounted on the instrument panel body 1.

[0102] The first insert plate is inserted into the first groove, and the second insert plate is inserted into the second groove, so that the first end 21 is on the side of the second end 22 close to the central axis of the vehicle, and the satellite antenna 31 is positioned close to the central axis of the vehicle. The satellite antenna 31 receives and transmits signals through the space at the windshield of the vehicle.
