Description

Technical Field

[0001] This invention relates to an antenna cover for an onboard antenna, and more particularly to an onboard antenna cover mounting structure. Background Technology

[0002] In existing automotive head units, onboard antennas are often used, with the antenna unit formed on the head unit's circuit board. This means the circuit board contains both the head unit's main circuit mounting area and the antenna mounting area. However, considering the head unit's main circuit, it often requires a shielded housing with shielding capabilities. Therefore, a separate antenna cover is needed to protect the onboard antenna. The antenna mounting area on the circuit board extends from an opening on the side of the shielded housing. The antenna cover is placed over the antenna mounting area and secured with plastic clips and a screw. This process requires not only clip alignment and screw tightening but also, because the edges of the shielded housing need to be filled with conductive adhesive for EMC shielding, a gap must be created between the edge of the shielded housing forming the opening and the main board. During screw tightening, due to gap precision and matching issues, the antenna cover may lift, causing misalignment of the screw holes. This necessitates re-pressurization with a fixture, further increasing the difficulty of assembly and automation.

[0003] To address this, Chinese patent CN215989244U discloses an onboard antenna cover and a host structure with an onboard antenna. Elastic arms that can deform in the vertical direction are formed on the upper and lower sidewalls of the onboard antenna cover. During assembly, the upper and lower shells of the host press and engage the elastic arms of the antenna cover from the upper and lower sides to fix the antenna cover to the host shell. However, this antenna cover assembly method requires simultaneous assembly with the upper and lower shells of the host shell. Therefore, a specialized positioning device must be used to position and fix the antenna cover during the assembly of the upper and lower covers to prevent misalignment due to compression during assembly. This method is costly, inconvenient to assemble, and the antenna cover may detach from part of the onboard antenna during prolonged use, affecting the protective function of the antenna cover.

[0004] Therefore, there is an urgent need for an onboard antenna cover mounting structure that can solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide an onboard antenna cover mounting structure for a main unit in a smart cockpit. The antenna cover is easy to assemble, has a high yield rate, and the connection between the antenna cover and the circuit board is stable after assembly.

[0006] To achieve the above objectives, the present invention discloses an onboard antenna cover mounting structure, including a circuit board and an antenna cover. The circuit board includes a main circuit section and an antenna section of the main circuit section located near the edge of the circuit board. The antenna cover includes a cover body and latching arms protruding outward from two opposite side walls of the cover body. A receiving cavity for accommodating the antenna section is formed on the cover body. A latching block protrudes upward from the end of each latching arm. A latching notch is formed on the circuit board for engaging with the latching blocks of the latching arms. An upper positioning block and a lower positioning block spaced apart in the vertical direction are provided in the receiving cavity. A positioning area is formed between the upper and lower positioning blocks to cooperate with the plate of the antenna section and position the plate in the vertical direction. The antenna cover engages with the circuit board in the horizontal direction through the latching blocks and the latching notches. The antenna section engages with the positioning area in the vertical direction.

[0007] Compared with existing technologies, this invention features two latching arms on the antenna cover to engage with notches on the circuit board, effectively preventing the antenna cover from detaching from the circuit board and exposing the antenna portion, thus ensuring a stable connection between the antenna cover and the circuit board after assembly. Furthermore, the antenna cover of this invention also includes positioning areas for vertically positioning the antenna portion, further stabilizing the antenna cover's installation. Moreover, during assembly, the antenna cover is first latched onto the circuit board, ensuring its proper positioning and preventing the antenna cover from jumping or shifting during housing assembly. This facilitates assembly and results in a high yield rate.

[0008] Preferably, the onboard antenna cover mounting structure further includes a housing, the housing including an upper cover and a lower cover, the upper cover and the lower cover being fitted together to form a main mounting cavity for accommodating the main circuit section, the cavity wall of the main mounting cavity being provided with a through hole for the antenna section to pass through, the sidewalls of the upper cover and the lower cover through which the antenna section passes through being provided with an upper abutment and a lower abutment respectively cooperating with the upper side and the lower side of the antenna cover, the upper cover and the lower cover being fitted together to form a clamping area between the upper abutment and the lower abutment to clamp the antenna cover from the upper and lower sides.

[0009] Specifically, the end of the upper abutment protrudes downward to form a hook portion, and the upper edge of the inlet of the receiving cavity protrudes upward to engage with the hook portion. When the upper cover and the lower cover are installed together, the upper flange abuts against the upper abutment and engages with the hook portion at the same time.

[0010] More specifically, the upper flange is provided with a plurality of grooves to divide the upper flange into a plurality of parts, and a guide abutment block is provided on the inner side of each upper flange, and the hook portion abuts against the guide abutment block of the upper flange.

[0011] Specifically, the lower edge of the inlet of the receiving cavity is bent downward to form an elastic abutment arm. The bottom wall of the receiving cavity is provided with two grooves that penetrate the bottom wall to allow the elastic abutment arm to elastically deform in the vertical direction. When the upper cover and the lower cover are installed together, the lower abutment abuts against the end of the elastic abutment arm to cause the elastic abutment arm to deform and bend upward.

[0012] Preferably, the antenna portion is formed at the corner of the circuit board, and the corner is formed by the intersection of a first sidewall and a second sidewall that are set at a preset angle. The first sidewall and the second sidewall each include a first edge portion and a second edge portion forming the corner. The first edge portion is translated inward to form a first locking wall between the first edge portion and the second edge portion. The second edge portion is recessed inward at a position where there is a gap between it and the first locking wall to form the locking notch.

[0013] Specifically, the two latching arms include a first latching arm corresponding to the extension direction of the first sidewall and a second latching arm corresponding to the extension direction of the second sidewall. The first latching arm is a first elastic latching arm that can be bent in the vertical direction, and the second latching arm is a second elastic latching arm that can be bent in the horizontal direction. The upper side of the latching block on the first elastic latching arm gradually tilts downward to form a first guide wall, and the first latching wall on the second sidewall gradually extends outward while gradually tilting away from the corner to form a second guide wall.

[0014] Specifically, the left and right walls of the cavity inlet are respectively provided with a left flange and a right flange protruding outwards, and the first latching arm and the second latching arm are respectively provided on the left flange and the right flange.

[0015] Preferably, there are multiple upper positioning blocks that protrude from the left and right cavity walls of the receiving cavity, and multiple lower positioning blocks that protrude from the lower cavity wall of the receiving cavity, with an inclined third guide wall formed on the front side of the lower positioning block.

[0016] This invention discloses a main unit for a smart cockpit, comprising a housing, a circuit board, and an antenna cover. The circuit board is mounted using an onboard antenna cover mounting structure as described above, and the main circuit section of the circuit board is housed within the main mounting cavity of the housing.

[0024] To illustrate the technical content, structural features, objectives, and effects of the present invention in detail, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0025] refer to Figures 1 to 3 This invention discloses a host 100 for a smart cockpit, including a housing 10, a circuit board 20, an antenna cover 30, and a data interface. The housing 10 includes an upper cover 11 and a lower cover 12. The circuit board 20 includes a main circuit section 21 and an antenna section 22 of the main circuit section 21 located near the edge of the circuit board 20. The upper cover 11 and the lower cover 12 are fitted together to form a main mounting cavity for accommodating the main circuit section 21. The cavity wall of the main mounting cavity is provided with a through hole 13 for the antenna section 22 to pass through. The main circuit section 21 of the circuit board 20 is mounted on the main mounting cavity, and the antenna section 22 is exposed outside the main mounting cavity through the through hole 13. The antenna cover 30 is engaged with the circuit board 20 and covers the antenna cover 30. The data interface is electrically connected to the circuit board 20. This data interface is a wireless interface and / or a wired interface.

[0026] refer to Figure 3 , Figure 4 and Figure 7The antenna cover 30 includes a cover body 31 and latching arms (first latching arm 321 and second latching arm 322) protruding outward from two opposite side walls of the cover body 31. The cover body 31 has a receiving cavity 311 for accommodating the antenna portion 22. The ends of the latching arms (first latching arm 321 and second latching arm 322) are provided with upwardly protruding engaging blocks (first engaging block 3211 and second engaging block 3221). The circuit board 20 has engaging blocks (first engaging block 3211 and second engaging block 3221) respectively engaging with the latching arms (first latching arm 321 and second latching arm 322). 1) Engaging notches (first engagement notch 231, second engagement notch 232): The receiving cavity 311 is provided with an upper positioning block 332 and a lower positioning block 331 with a distance between them in the vertical direction. The upper positioning block 332 and the lower positioning block 331 form a positioning area that cooperates with the plate of the antenna part 22 and positions the plate in the vertical direction. The antenna cover 30 engages with the circuit board 20 in the horizontal direction through the engagement blocks (first engagement block 3211, second engagement block 3221) and the engagement notches (first engagement notch 231, second engagement notch 232). The antenna part 22 engages with the positioning area in the vertical direction.

[0027] refer to Figure 3 The upper cover 11 and lower cover 12 have outwardly protruding upper abutment 111 and lower abutment 121 on their sidewalls through which the antenna section 22 passes, respectively engaging with the upper and lower sides of the antenna cover 30. The upper cover 11 and lower cover 12 are fitted together, forming a clamping area between the upper abutment 111 and lower abutment 121 that holds the antenna cover 30 from both sides. This design allows the upper cover 11 and lower cover 12 to press the antenna cover 30 into the middle from both sides, eliminating the need for threaded connections. The lower abutment 121 is formed by a cut in the sidewall of the lower cover 121 and an expansion resulting in a protrusion. The lower side of the antenna cover 30 abuts against the cut surface, which is a straight surface.

[0028] refer to Figure 3 The upper abutment 111 has a downward protruding hook portion 112 at its end. The upper edge of the inlet of the receiving cavity 311 has an upward protruding upper flange 314 that engages with the hook portion 112. When the upper cover 11 and the lower cover 12 are installed together, the upper flange 314 abuts against the upper abutment 111 and engages with the hook portion 112 at the same time. The upper flange 314 is locked in the groove between the hook portion 112 and the upper shell 11.

[0029] refer to Figure 4 and Figure 6The upper flange 314 has multiple grooves to divide it into multiple sections, and each upper flange 314 has a guide contact block 3141 protruding from its inner side. The hook portion 112 abuts against the guide contact block 3141 of the upper flange 314. The guide contact block gradually thickens from top to bottom so that when the hook portion 112 presses down on the antenna cover 30, it gradually engages with the side wall of the upper shell 11 to clamp the upper flange 314. The hook portion 112 has a locking protrusion protruding from its inner side that engages with the grooves on the upper flange 314 to position the relative position between the antenna cover 30 and the upper cover 11. The locking protrusion connects the inner side of the hook portion 112 and the side wall of the upper cover 11 where the through hole 13 for the antenna portion 22 passes through is located. The upper cover 11 has a contact arm that gradually thickens from top to bottom on the side wall where the through hole 13 through which the antenna part 22 passes, so as to abut against the upper flange 314 to ensure that the hook part 112 engages with the side wall of the upper shell 11 to clamp the upper flange 314.

[0030] refer to Figure 2 , Figure 3 and Figure 7 The lower edge of the inlet of the receiving cavity 311 is bent downward and protruded with an elastic abutment arm 315. The bottom wall of the receiving cavity 311 is connected to the two sides of the elastic abutment arm 315 and has two grooves 316 that penetrate the bottom wall so that the elastic abutment arm can be elastically deformed in the vertical direction. When the upper cover 11 and the lower cover 12 are installed together, the lower abutment 121 abuts against the end of the elastic abutment arm 315 so that the elastic abutment arm 315 deforms and bends upward, thereby cooperating with the upper abutment block 111 to clamp the antenna cover 30.

[0031] refer to Figure 4 The antenna portion 22 is formed at the corner of the circuit board 20. The corner is formed by the intersection of a first sidewall and a second sidewall that are set at a preset angle. The first sidewall and the second sidewall each include a first edge portion and a second edge portion that forms the corner. The first edge portion is translated inward so that a first locking wall 233 is formed between the first edge portion and the second edge portion. The second edge portion is recessed inward at a position where there is a gap between it and the first locking wall 233 to form the locking notch (first locking notch 231, second locking notch 232).

[0032] The antenna section 22 is fitted with a plate that matches the shape and size of the receiving cavity 311, thereby restricting the lateral movement of the antenna section 22 by the left and right walls of the receiving cavity 311. In this embodiment, the corner is triangular.

[0033] In this embodiment, a circuit board 20 has two antenna sections 22, and antenna covers 30 are respectively installed on the two antenna sections 22. The two antenna sections 22 are located at two corners of the circuit board 20 and form a triangle. The cover body 31 of the two antenna covers 30 is also triangular and is correspondingly fitted on the corresponding corners of the circuit board 20 to cover the antenna sections 22.

[0034] refer to Figure 4 The two latching arms include a first latching arm 321 corresponding to the extension direction of the first sidewall and a second latching arm 322 corresponding to the extension direction of the second sidewall. The engaging notches include a first engaging notch 231 that engages with a first engaging block 3211 on the first latching arm 321 and a second engaging notch 232 that engages with a second engaging block 3221 on the second latching arm 322. The first latching arm 321 is a first elastic latching arm that can be bent in the vertical direction, and the second latching arm 322 is a second elastic latching arm that can be bent in the horizontal direction. The upper side of the engaging block 3211 on the first elastic latching arm gradually tilts downward to form a first guide wall 3212, and the first latching wall 233 on the second sidewall gradually extends outward while gradually tilting away from the corner to form a second guide wall.

[0035] refer to Figure 4 and Figure 7 The left and right walls of the inlet of the receiving cavity 311 are respectively provided with a left flange 312 and a right flange 313 protruding outwards, and the first latching arm 321 and the second latching arm 322 are respectively provided on the left flange 312 and the right flange 313.

[0036] refer to Figure 3 , Figure 5 and Figure 7 The upper positioning blocks 332 are multiple and protrude from the left and right cavity walls of the receiving cavity 311 respectively. The lower positioning blocks 331 are multiple and protrude from the lower cavity wall of the receiving cavity 311. The front side of the lower positioning blocks 331 forms an inclined third guide wall 3311.

[0037] refer to Figure 3 To further increase the stability of the main unit 100 assembly, the circuit board 20 has a fixing point in the middle of the connection position between the antenna part 22 and the main circuit part 21. The screw 40 passes through the fixing point to fix the circuit board 20 to the housing 10. Specifically, the circuit board 20 is fixed to the upper housing 11 through the fixing point.

[0038] refer to Figures 1 to 7This invention describes a method for assembling an antenna cover 30. A circuit board 20 and the antenna cover 30 are provided. The antenna cover 30 is placed laterally on the antenna portion 22. A first latching arm 321 is pushed forward along the extending direction of the first sidewall. When the first guide wall 3212 contacts the first latching wall 233 on the first sidewall, the first latching wall 233 cooperates with the first guide wall 3121 to press the first engaging block 3211 downwards. The first latching arm 321 then bends downwards and slides along the lower side of the circuit board 20 until the antenna cover 30 is pushed into place. After this, the first engaging block 3211 extends from the first engaging notch 231 to reset the first latching arm 321, and the first engaging block 3211 engages with the first engaging notch 231. When the second engaging block 3221 contacts the second guide wall on the first engaging wall 233 of the second sidewall, the second latching arm 322 bends outward under the guidance of the second guide wall until the second engaging block 3221 extends into the second engaging notch 232. The second latching arm 322 then resets, so that the engaging blocks (first engaging block 3211, second engaging block 3221) and the engaging notch engage with the circuit board 20 in the lateral direction. During this process, the plate of the antenna part 22 gradually enters between the upper positioning block 332 and the lower positioning block 331 under the action of the third guide wall 3311 as the antenna cover 30 is pushed forward, so that the antenna part 22 engages with the positioning area in the vertical direction.

[0039] The upper cover 11 and the lower cover 12 are provided, the main circuit board 20 is installed between the upper cover 11 and the lower cover 12, and the upper cover 11 and the lower cover 12 are fastened together so that the main mounting cavity accommodates the main circuit section 21. Specifically, the main circuit board 20 is fixed to the upper cover 11 with a plurality of screws, and then the lower cover 12 is fastened to the upper cover 11 and fixed with screws.

[0040] The horizontal direction described in this invention is a plane perpendicular to the vertical direction, which is the direction of the circuit board surface. Up, down, left, and right are also relative directions, not absolute directions.

[0041] The above-disclosed embodiments are merely preferred embodiments of the present invention and should not be construed as limiting the scope of the present invention. Therefore, any equivalent variations made in accordance with the claims of the present invention are still within the scope of the present invention.
