Description

[Technical Field]

[0001] TECHNICAL FIELD This application relates to the field of electronic device technology, and more particularly to electronic devices. [Background technology]

[0002] The antennas in conventional in-vehicle products are generally in the form of a support antenna, that is, an antenna steel plate is attached to a circuit board of the product via a dedicated support. However, with the evolution of in-vehicle products, the traditional support antenna solution cannot meet the requirements of customers or products because the traditional support antenna requires a dedicated support configuration, resulting in complex antenna assembly, a significantly larger occupied space, and excessive mass of the support antenna. Summary of the Invention

[0003] The purpose of the present application is to provide an electronic device that solves the problems of existing support antennas, such as the complex assembly of the antenna, the large space occupied, and the excessive mass of the support antenna.

[0004] This application is A mechanical component having a plurality of support ribs arranged thereon, wherein protrusions of the plurality of support ribs are spaced apart in a first direction and there are gaps between the protrusions of at least some of the support ribs in a second direction, and the second direction is perpendicular to the first direction; an antenna body, the antenna body being disposed in the gap; An electronic device including:

[0005] According to the electronic device provided in the present application, the support ribs are arranged on the mechanical part without designing a separate dedicated support for mounting the antenna body. To ensure the fixation of the antenna body, the antenna body is mounted in the gap between the support ribs. This saves space in the electronic device, reduces the weight of the electronic device, facilitates the mounting of the antenna body, and facilitates its operation.

[0006] In addition, the protrusions of the support ribs are spaced apart in the first direction to allow for normal demolding after heat fusing by the mold without modifying the existing structure of the mold. In this way, to ensure the reliability of the connection between the antenna body and the mechanical component, the antenna body and the mechanical component can be connected using a heat fusing process. In addition, to ensure the reliability of the fixation of the antenna body to the mechanical component, the support ribs can be located at different positions on the antenna body.

[0007] In a possible design, the multiple support ribs include at least one first support rib and multiple second support ribs. The first support rib and the second support rib are located at both ends of the antenna body, respectively. In the first direction, a protrusion of at least one first support rib is located between two adjacent protrusions of the second support ribs. In this way, the antenna body can be supported and positioned at multiple positions, ensuring reliable attachment of the antenna body to mechanical components. There is no need to design a separate, dedicated support for attaching the antenna body. This saves space in the electronic device, reduces the weight of the electronic device, and facilitates attachment and operation of the antenna body.

[0008] In a possible design, the projections of the first and second support ribs are spaced apart in alternating directions in the first direction.

[0009] In a possible design, the antenna body includes an upright portion, which is of flat plate construction.

[0010] The thickness of the entire upright portion having a flat structure is uniform and consistent. There can be a uniform gap between the support ribs in the first direction, so that the upright portion can be clamped in the gap, and the stability of clamping the upright portion can be ensured.

[0011] In a possible design, the antenna body includes an upright portion on which a bending structure bent in the first direction is arranged, and at least some of the support ribs are arranged on the sides of the bending structure.

[0012] At least one support rib is disposed on the side of the bending structure in the first direction to support the bending structure and ensure the shape of the bending structure. In addition, the support rib located on the bending structure and the protrusions of the other support ribs in the first direction are spaced apart, which can facilitate demolding and allow the connection and fixing between the antenna body and the mechanical part to be achieved by a hot-melting process.

[0013] In a possible design, the antenna body further comprises a connection part, which is connected to the upright part, and the upright part is fixed to the mechanical part via the connection part, thereby ensuring a reliable connection and fixation between the antenna body and the mechanical part.

[0014] In a possible design, the connector is fixed to the mechanical part via a hot-melt connection, a rivet connection, or a screw connection. Regardless of the fixing method used, the connector can be fixed to the mechanical part at the height of the antenna body, which can facilitate operation and, if a hot-melt process is used, demolding.

[0015] In one possible design, at least one feed portion is disposed on the antenna body, the feed portion being bent in a first direction toward a side of the antenna body, and the feed portion being supported by a support rib.

[0016] The side of the feed part behind the support rib can be abutted against the PCB by using a spring, and the side of the feed part behind the PCB can be supported by the support rib, preventing the feed part from being deformed by the spring pushing out. In this way, the life of the feed part can be extended. This ensures that the antenna body can be reliably connected to the PCB via the feed part for a long period of time.

[0017] In a possible design, the height of the support rib is equal to or greater than the height of the antenna body, thus maximizing the contact area between the support rib and the antenna body in the height direction, and improving the effect of restricting and supporting the antenna body.

[0018] In a possible design, the feeds are connected to the tops of said support ribs, and after the antenna body is mounted in place, the feeds can be supported by the support ribs by connecting them to the tops of the corresponding support ribs.

[0019] In one possible design, bosses are located on the side walls of the support ribs, and the power supply is connected to the bosses.

[0020] The bosses may be located at positions in the height direction of the support ribs. In this embodiment, the power feeds do not need to contact the tops of the support ribs, but may contact bosses on the support ribs. The power feeds may also be supported by the bosses. It will be understood that the projections of the bosses on the support ribs in the first direction and the projections of the bosses on other support ribs and thereon are spaced apart in the first direction to facilitate normal demolding.

[0021] In a possible design, the power feed is fixed to the support rib via a heat-melted connection, a rivet connection, or a screw connection, which ensures a reliable connection between the power feed and the support rib and ensures that the support rib effectively supports the power feed.

[0022] In one possible design, a first heat-fusible pole is disposed on the support rib. The power supply part has a first position hole through which the first heat-fusible pole passes. The support rib and the power supply part are connected via heat fusion and engagement of the first heat-fusible pole with the first position hole. The first position hole engages with the first heat-fusible pole, ensuring positional accuracy of the engagement between the power supply part and the support rib.

[0023] In a possible design, the connection part is provided with an escape notch, and the support rib is located in the escape notch. In this way, during the installation process, the escape notch can be aligned with the corresponding support rib, and the upright part of the antenna body can be clamped in the gap. Finally, the connection part can be abutted against a mechanical part to facilitate subsequent fastening operations.

[0024] In a possible design, a limiting protrusion is disposed on the mechanical part. The limiting protrusion is disposed within the avoidance notch. In a second direction, the limiting protrusion abuts against a side wall of the avoidance notch. The second direction is perpendicular to the first direction. The limiting protrusion can contact the side wall of the avoidance notch in the second direction, thereby limiting movement of the antenna body in the second direction. This ensures the reliability of the connection and fastening between the antenna body and the mechanical part.

[0025] In a possible design, the at least some of the support ribs include a first stiffener and a second stiffener, an end of the first stiffener being fixedly connected to an end of the second stiffener, and a slot for clamping the antenna body is provided between the first stiffener and the second stiffener.

[0026] Since the first stiffener and the second stiffener are located on both sides of the antenna body, respectively, the antenna body is restricted in the first direction from two sides of the antenna body, which further ensures the reliability of the connection between the antenna body and the mechanical components.

[0027] In a possible design, the mechanical parts and the support ribs are formed integrally, which ensures the reliability of the entire structure.

[0028] In a possible design, the width dimension of the gap is equal to or greater than the thickness dimension of the antenna body, so that the antenna body can be easily clamped into the gap, facilitating the installation of the antenna body and ensuring the reliability of the clamping of the antenna body.

[0029] In possible designs, the material of the support ribs is plastic, glass, or ceramic. In this embodiment, plastic is preferably used. In one aspect, plastic can facilitate processing and production and has low cost. In another aspect, plastic helps to implement weight reduction of electronic devices.

[0030] In a possible design, the electronic device comprises an in-vehicle device.

[0034] In order to facilitate a better understanding of the technical solutions of the present application, the embodiments of the present application are described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate the present application and are not intended to limit the present application.

[0035] In the description of this application, unless otherwise specified and limited, the terms "first" and "second" are intended for descriptive purposes only and should not be understood as indicating or implying relative importance. Unless otherwise specified or described, the term "plurality" means two or more. Terms such as "connected," "fixed," etc. should be understood broadly. For example, "connected" may be a fixed connection, or a detachable connection, an integral connection, an electrical connection, a direct connection, or an indirect connection via an intermediate medium. Those skilled in the art may interpret the specific meaning of the above terms in this application based on the specific circumstances.

[0036] Conventional in-vehicle products generally require wireless signal reception and transmission functions. In this case, an antenna must be built into the product. Existing antennas generally take the form of a support antenna. That is, the antenna includes an antenna steel plate and a dedicated support. The antenna steel plate is fixed to the dedicated support. The dedicated support can be fixed to a circuit board in the product via screws or fasteners, or the dedicated support can be welded to the circuit board. However, the dedicated support is large in size. As a result, a large installation space is required in the product, and the dedicated support occupies a large area on the circuit board. This poses significant challenges to the miniaturization and weight reduction of products and the integration of electronic components.

[0037] An embodiment of the present application provides an electronic device. The electronic device may be a mobile phone, a tablet computer, a desktop computer, a laptop computer, a handheld computer, a notebook computer, an ultra-mobile personal computer (UMPC), a netbook, a mobile phone, a personal digital assistant (PDA), an augmented reality (AR) device, a virtual reality (VR) device, an artificial intelligence (AI) device, a wearable device, an in-vehicle device, a smart home device, and / or a smart city device. The embodiment of the present application is not limited to a specific type of electronic device. For ease of explanation, the present application uses an example in which the electronic device is an in-vehicle device.

[0038] The electronic device includes a mechanical part 1 and an antenna body 3. The mechanical part 1 can be the housing of an electronic product or a structure, such as the housing of some functional components, a connecting rib, or a reinforcing rib. The mechanical part 1 can perform component mounting, protection, support, etc.

[0039] As shown in FIGS. 1 to 4, a plurality of support ribs 2 are arranged on a mechanical component 1. 1 Direction Y The protrusions of the plurality of support ribs 2 in the second direction are spaced apart. X In the second direction, there is a gap H between at least some of the protrusions of the support rib 2. X is the first direction Y , which is perpendicular to the support ribs 2. There are two, three, four or more support ribs 2. When the antenna body 3 is clamped in the gap H between the support ribs 2, both sides of the antenna can abut against each support rib 2. The stability of the clamping of the antenna can be ensured via each support rib 2.

[0040] In this way, the support ribs 2 are arranged on the mechanical part 1 without designing a separate dedicated support for mounting the antenna body 3. The antenna body 3 is mounted in the gap H between the support ribs 2 to ensure secure fixation of the antenna body 3. This saves space for the electronic device, reduces the weight of the electronic device, and facilitates the mounting and operation of the antenna body 3.

[0041] In addition, when the antenna body 3 is assembled to the mechanical part 1 of the electronic device, those skilled in the art generally consider using a heat melting process to heat melt the antenna body 3 to the mechanical part 1. However, the mechanical part 1 of the electronic device generally has an irregular shape and a complex structure, and it is inconvenient to use a mold to heat melt the antenna body 3 to the structure. Even if a mold can be used to achieve the heat melt connection between the antenna body 3 and the mechanical part 1, since the mechanical part 1 has a complex structure, for example, multiple structural ribs and spacers, the mold may interfere or demolding may not be possible. In particular, 2 In the direction X, both sides of the antenna body 3 surface In the case of a structure in which the protrusions of the support ribs 2 overlap, the two opposing support ribs 2 interfere with demolding. As a result, demolding of the existing heat-melting mold cannot be performed, and therefore the antenna body 3 and the mechanical component 1 cannot be joined by heat fusion.

[0042] In view of this, in the present application, as shown in FIG. 4, in order to perform normal demolding after heat melting by a mold without changing the structure of an existing mold, Y The protrusions of the support rib 2 at the antenna body 3 are spaced apart. In this way, the antenna body 3 and the mechanical part 1 are joined by using a thermal fusion process, ensuring the reliability of the joining between the antenna body 3 and the mechanical part 1. In addition, the support rib 2 can be located at different positions on the antenna body 3 to ensure the reliability of the fixing of the antenna body 3 to the mechanical part 1.

[0043] 4, the plurality of support ribs 2 include at least one first support rib 21 and a plurality of second support ribs 22. The first support rib 21 and the second support rib 22 are disposed on both sides of the antenna body 3. surface The first direction is Y In the figure, the protrusion of at least one first support rib 21 is located between the protrusions of two adjacent second support ribs 22.

[0044] Optionally, the first direction Y The protrusions of the first support rib 21 and the second support rib 22 in the first direction are spaced apart from each other. Y In this example, the protrusion of one first support rib 21 is adjacent to the protrusion of one second support rib 22. When there are a plurality of first support ribs 21 and a plurality of second support ribs 22, the protrusions of the first support ribs 21 and the second support ribs 22 are arranged alternately, so that uniform stress can be applied to the antenna body 3, and harmful deformation caused by uneven stress on the antenna body 3 can be avoided.

[0045] In one embodiment, as shown in FIGS. 3 to 5, when there are three support ribs 2, for example, when there is one first support rib 21 and two second support ribs 22, the protrusions of the three support ribs 2 are oriented in a first direction. Y The first support rib 21 may be located on one side of the antenna body 3. The two second support ribs 22 may be located on the other side of the antenna body 3. In addition, the protrusion of the separate first support rib 21 located on the other side of the antenna body 3 is located between the protrusions of the two second support ribs 22 located on the other side of the antenna body. In this way, uniform stress can be applied to the antenna body 3, and the antenna body 3 is prevented from being subjected to uneven stress and causing harmful deformation.

[0046] In another embodiment, when there are four or more support ribs 2, the projections of the four or more support ribs 2 are in the first direction. Y6, when there are two first support ribs 21 on one side of the antenna body 3 and two second support ribs 22 on the other side of the antenna body 3, the protrusions of the two first support ribs 21 and the two second support ribs 22 can be evenly and alternately distributed, or the protrusions of the two first support ribs 21 can be located together between the protrusions of two adjacent second support ribs 22. Regardless of which method is used to arrange the support ribs 2, the first direction Y The protrusions of the support rib 2 can be spaced apart, and the antenna body 3 can be supported and positioned at multiple positions. This ensures the reliability of the attachment of the antenna body 3 to the mechanical component 1.

[0047] In addition, in yet another embodiment, when there are two support ribs 2, that is, when one first support rib 21 and one second support rib 22 are respectively arranged on both sides of the antenna body 3, the positions of the two support ribs 2 are Y In this way, the first direction Y In this case, there is a specific interval between the protrusions of the two support ribs 2, and 2 Direction X There is a certain gap H between the two support ribs 2. The antenna body 3 can be clamped at the gap H. surface The protrusions of the two support ribs 2 can abut against the two support ribs 2, respectively. The stability of the clamping of the antenna can be ensured through the support of the two support ribs 2. In addition, the protrusions of the two support ribs 2 can abut against the first 2 Direction XSince the support ribs 2 are offset from each other at the distance, the two support ribs 2 can abut on two different positions on the antenna body 3, ensuring the stability of the antenna mounting. In addition, the support ribs 2 are arranged on the mechanical part 1 without designing a separate dedicated support for mounting the antenna body 3. To ensure the secure fixation of the antenna body 3, the antenna body 3 is mounted in the gap H between the support ribs 2. This saves space in the electronic device, reduces the weight of the electronic device, and facilitates the mounting and operation of the antenna body 3. Specifically, in one embodiment, as shown in Figures 7 and 8, the antenna body 3 includes an upright portion 31. The upright portion 31 has a flat plate structure. The thickness of the upright portion 31 having a flat plate structure is uniform and consistent throughout. 2 There may be a uniform gap H between the support ribs 2 in the direction X, so that the uprights 31 can be clamped at the gap H to ensure stable clamping of the uprights 31. The uprights 31 having a flat structure may have a regular shape for ease of processing, manufacturing, and assembly to the mechanical component 1. The uprights 31 may be a thin metal plate. The metal plate may be made of steel, copper, silver, etc. The thickness of the metal plate may be 0.4 mm, 0.5 mm, 0.6 mm, etc., or may have other thickness dimensions, which may be specifically determined according to the antenna performance.

[0048] In another embodiment, instead, 2 There may be non-uniform gaps between the support ribs 2 in the direction X of the antenna body 3. For example, if the thickness of the antenna body 3 is non-uniform, non-uniform gaps may be arranged between the support ribs 2 to ensure reliable fixation of the antenna body 3. In addition, it will be understood that a uniform gap is a substantially uniform gap. Certain tolerances arising in the manufacturing or assembly process are allowed for.

[0049] However, in the case of a mechanical part 1 having a complex structure, it may be difficult to widen the gap H used to clamp the antenna body 3 along a straight line, or the antenna body 3 may not necessarily have a flat structure based on the radiation performance of the antenna. As a result, in another embodiment, the antenna body 3 includes an upright portion 31, as shown in FIG. 9. YA bending structure 34 bent in the upright portion 31 is disposed on the upright portion 31. A part of the support rib 2 is disposed on the side of the bending structure 34.

[0050] 9, the bending structure 34 may be, but is not limited to, a U-shape, a V-shape, a W-shape, etc. The bending structure 34 is configured to be oriented in a first direction. Y For example, if there is one bending structure 34, the bending structure 34 may be bent toward either side of the antenna body 3 in a first direction. Y In this case, the bending structure 34 may be bent toward the side opposite to the side of the upright portion 31. When there are two or more bending structures 34, the bending directions of the bending structures 34 may be the same or partially different. Optionally, for all of the bending structures 34 or for some of the bending structures 34, the first direction Y In the first direction, at least one support rib 2 may be disposed on one or both sides of the bending structure 34. The bending structure 34 may be supported by the support rib 2 to ensure the shape of the bending structure. Y 2, the support rib 2 located on the bending structure 34 and the protrusions of other support ribs 2 are spaced apart, which facilitates demolding and allows the antenna body 3 and the mechanical part 1 to be connected and fixed at each position by using a thermal melting process.

[0051] As shown in FIG. 9, when there are support ribs 2 on both sides of the bending structure 34, the second direction X , there is a gap H between the protrusions of the support ribs 2 on both sides of the same bending structure 34, and the antenna body 3 can be securely fixed in the gap H.

[0052] In addition, as shown in FIG. 9, when the antenna body 3 has a bending structure 34, the second direction X In the second direction, the support rib 2 may be further disposed on one or both sides of a portion of the bending structure 34. X The first direction of the support ribs 2 on both sides of the same bending structure 34 in Y There is a gap H' between the protrusions at the center of the antenna body 3. The gap H' can be used to mount the antenna body 3 to improve the reliability of the fixing of the antenna body 3.

[0053] The dimensions of the bent structure, such as the bend depth, curvature, and opening width, may be determined based on the size of the structure that needs to be avoided or the radiation performance of the antenna, but the embodiment of the present application is not limited thereto.

[0054] 7 and 8, the antenna body 3 further includes a connecting portion 32. The connecting portion 32 is connected to the upright portion 31. The upright portion 31 is fixed to the mechanical component 1 via the connecting portion 32.

[0055] There is a risk of fluttering if the uprights 31 are clamped between the support ribs 2. In view of this, the antenna body 3 can be fixedly connected to the entire mechanical part 1 via the connection parts 32. This ensures a reliable connection and fixation between the antenna body 3 and the mechanical part 1.

[0056] The antenna body 3 may have an integrally formed structure. Specifically, the upright portion 31 and the connecting portion 32 may be integrally formed when the antenna body 3 is manufactured. This facilitates processing and manufacturing, and also improves the structural reliability of the antenna body 3. The upright portion 31 and the connecting portion 32 may be connected perpendicularly to each other. The connecting portion 32 may be a metal plate. The metal plate has a large area. In this way, there is a large contact area between the connecting portion 32 and the mechanical component 1 to ensure the stability of the antenna body 3.

[0057] Specifically, the connecting portion 32 can be fixed to the mechanical component 1 by a thermal fusion connection, a rivet connection, or a screw connection. Regardless of which fixing method is used, the connecting portion 32 can be fixed to the mechanical component 1 in the height direction of the antenna body 3. For example, when a rivet connection method is used, a rivet can be inserted into the connecting portion 32 in the height direction of the antenna body 3 and then fixed to the mechanical component 1. When a thermal fusion connection method is used, a specific position of the connecting portion 32 or the mechanical component 1 can be thermally fused in the height direction of the antenna body 3 by using a thermal fusion mold. In this way, the connecting portion 32 can be fixed to the mechanical component 1 in the height direction of the antenna body 3, which facilitates the process and also facilitates demolding when a thermal fusion process is used.

[0058] As shown in FIG. 7 , the connecting portion 32 has a second position hole 321. As shown in FIG. 5 , the mechanical component 1 has a second heat-fusible pole 12. The second heat-fusible pole 12 passes through the second position hole 321. The antenna body 3 is connected to the mechanical component 1 through the heat-fusion and engagement of the second heat-fusible pole 12 and the second position hole 321. In a specific installation process of the antenna body 3, the second position hole 321 of the connecting portion 32 is pre-sleeved onto the second heat-fusible pole 12 to perform pre-positioning, and a heat-fusible mold is used to heat-fuse the portion of the second heat-fusible pole 12 that passes through and exceeds the second position hole 321, thereby achieving a fixed connection between the connecting portion 32 and the mechanical component 1. In this way, the second position hole 321 is engaged with the second heat-fusible pole 12 to ensure the positional accuracy of the connecting portion 32 and the mechanical component 1.

[0059] Optionally, as shown in FIGS. 7 and 8 , an avoidance notch 322 is arranged in the connection portion 32. The support rib 2 is arranged in the avoidance notch 322. In a possible implementation, the support rib 2 can be part of the mechanical part 1. The layout of the support rib 2 is determined before the antenna body 3 is attached. When this design is used, the support rib 2 cannot be moved or changed. In this case, the antenna body 3 can be attached to the gap H only in the height direction of the support rib 2. Therefore, to avoid interference between the antenna body 3 and the support rib 2 during the attachment process, the avoidance notch 322 can be arranged in the connection portion 32. During attachment, the avoidance notch 322 can be aligned with the corresponding position of the support rib 2. Then, the upright portion 31 of the antenna body 3 can be clamped in the gap H. Finally, the connection portion 32 can be abutted against the mechanical part 1, which facilitates the subsequent fastening operation.

[0060] Optionally, as shown in FIGS. 4 and 5, a limiting protrusion 11 is disposed on the mechanical component 1. The limiting protrusion 11 is disposed in the avoidance notch 322. 1 In the direction Y, the limiting protrusion 11 abuts against the side wall of the avoidance notch 322. 1 The direction Y is the 2 is perpendicular to the direction X.

[0061] After the connecting portion 32 abuts against the mechanical component 1, the limiting protrusion 11 of the mechanical component 1 1 The limiting protrusion 11 can abut against the side wall of the avoidance notch 322 in the direction Y. 1 Since movement in the direction Y can be restricted, the reliability of the connection and fixation between the antenna main body 3 and the mechanical part 1 can be ensured.

[0062] In this way, the antenna body 3 is supported by the support ribs 2 in cooperation with each other. 2 The antenna body 3 is restricted from moving in the direction X by using the restricting protrusion 11. 1 By restricting the movement of the antenna body 3 in the direction Y, and by fixing the connection part 32 to the mechanical part 1 via a thermal fusion connection, a rivet connection or a screw connection, the movement of the antenna body 3 in the height direction is restricted, thereby ensuring the reliability of the connection between the antenna and the mechanical part 1.

[0063] Optionally, as shown in Figures 10 and 11, at least a portion of the support rib 2 includes a first stiffener 23 and a second stiffener 24. An end of the first stiffener 23 is fixedly connected to an end of the second stiffener 24. A slot 25 is provided between the first stiffener 23 and the second stiffener 24 for clamping the antenna body 3.

[0064] When the antenna body 3 is attached, the antenna body 3 is oriented in a first direction. Y The antenna body 3 can be clamped in the gap H between the stiffeners 23 and 24, and can be further clamped in the slot 25 between the first stiffener 23 and the second stiffener 24. Since the first stiffener 23 and the second stiffener 24 are located on both sides of the antenna body 3, respectively, the antenna body 3 can be clamped in the gap H between the stiffeners 23 and 24. 2 1. Therefore, the reliability of the connection between the antenna body 3 and the mechanical part 1 is further ensured.

[0065] As shown in Figure 11, 2Since the protrusions of the first stiffener 23 and the second stiffener 24 overlap in the direction X, if the heights of the first stiffener 23 and the second stiffener 24 are equal, demolding is difficult during the thermal fusion connection. In view of this, optionally, the height of the first stiffener 23 is set lower than that of the second stiffener 24. The height of the first stiffener 23 can be lower than that of the second stiffener 24. This facilitates demolding, and a fixed connection between the antenna body 3 and the mechanical part 1 can be achieved by using a thermal fusion process.

[0066] The support rib 2 formed by the first stiffener 23 and the second stiffener 24 can be formed integrally when the machine component 1 is manufactured.

[0067] For example, as shown in Figures 7 and 8, at least one power supply portion 33 is disposed on the antenna body 3. The power supply portion 33 is oriented in a first direction. YThe feed portion 33 is bent at the center and toward the side of the antenna body 3. The feed portion 33 is supported by the support rib 2. Optionally, the feed portion 33 may be connected to a circuit board, such as a printed circuit board (PCB), via a spring. The feed portion 33 and the PCB may push the spring to ensure reliable contact between the feed portion 33 and the PCB. However, when the feed portion 33 and the PCB push the spring, the spring also generates a reaction force against the feed portion 33, resulting in a certain degree of deformation of the feed portion 33. If the feed portion 33 is not supported by the support rib 2, the feed portion 33 will be irreversibly deformed after long-term use. As a result, the feed portion 33 cannot effectively push the spring, resulting in poor contact between the antenna body 3 and the PCB. In this embodiment, the support rib 2 and the PCB may be located on both sides of the feed portion 33. That is, the side of the power feed part 33 behind the support rib 2 can be brought into contact with the PCB using a spring, and the side of the power feed part 33 behind the PCB can be supported by the support rib 2, preventing deformation of the power feed part 33 due to the spring pushing out. In this way, the life of the power feed part 33 can be extended. The antenna body 3 can be reliably connected to the board via the power feed part 33 for a long period of time. Optionally, the number of power feed parts 33 can be set based on actual requirements. As shown in FIG. 7, there may be only one power feed part 33. As shown in FIG. 8, there may be two power feed parts 33. As shown in FIGS. 12 to 14, there may be three power feed parts 33.

[0068] Optionally, as shown in Figure 15, the height of the support rib 2 is equal to or greater than the height of the antenna body 3. In this way, the contact area between the support rib 2 and the antenna body 3 in the height direction can be maximized, and the effect of restricting and supporting the antenna body 3 can be improved. Of course, the height of the support rib 2 may alternatively be slightly lower than the height of the antenna body 3. In this case, stable support of the antenna can also be ensured.

[0069] For example, if the antenna body 3 has a uniform height, the height of the support rib 2 may be approximately equal to the height of the antenna body 3 to ensure stable support of the antenna body 3. In this embodiment, the heights of the support rib 2 may be equal.

[0070] For example, if the heights of different positions on the antenna body 3 are different, the heights of the support ribs 2 at different positions may be approximately equal to the heights of the corresponding positions on the antenna body 3. This ensures reliable support for antenna bodies 3 of different heights. In this embodiment, the heights of some or all of the support ribs 2 may be different, which may be specifically determined based on the heights of the positions that need to be fixed and are on the antenna body 3.

[0071] Optionally, the support ribs 2 have equal heights, so that the force applied from the support ribs 2 to the antenna body 3 is uniform and consistent. This avoids the problem of the antenna body 3 being bent and deformed due to an excessively large or small force being applied from the support ribs 2 to the antenna body 3. For example, if the height of the support ribs 2 on one side of the antenna body 3 is smaller than the height of the support ribs 2 on the other side of the antenna body 3, the support ribs 2 with greater heights will bend the antenna body 3 in the direction of the support ribs 2 with smaller heights. As a result, the antenna body 3 will bend. If the support ribs 2 on both sides of the antenna body 3 have the same height, stress will be applied evenly to both sides of the antenna body 3, avoiding the problem of the antenna body 3 bending sideways.

[0072] In a specific embodiment, the height of the support rib 2 is equal to the height of the antenna body 3, and the feed portion 33 is connected to the top of the support rib 2. After the antenna body 3 is mounted in place, the feed portion 33 can be joined to the top of the corresponding support rib 2, so that the feed portion 33 can be supported by the support rib 2.

[0073] In another specific embodiment, as shown in Fig. 15, a boss 26 is disposed on the side wall of the support rib 2. The power supply portion 33 is connected to the boss 26. The boss 26 may be located at a position in the height direction of the support rib 2. In this embodiment, the power supply portion 33 does not need to contact the top of the support rib 2, but may contact the boss 26 of the support rib 2. The power supply portion 33 can also be supported by the boss 26. Optionally, the first direction Y The boss 26 on the support rib 2 in the 1 Direction Y The other support ribs 2 and bosses 26 thereon are spaced apart to facilitate normal demolding.

[0074] Specifically, the power supply part 33 is fixed to the support rib 2 via a heat-melting connection, a rivet connection, or a screw connection, thereby ensuring the reliability of the connection between the power supply part 33 and the support rib 2 and ensuring that the support rib 2 effectively supports the power supply part 33.

[0075] Specifically, as shown in Fig. 5, the first heat-fusible pole 27 is disposed on the support rib 2. As shown in Fig. 7, the power supply part 33 has a first position hole 331 through which the first heat-fusible pole 27 passes. The support rib 2 and the power supply part 33 are connected via heat fusion and fitting between the first heat-fusible pole 27 and the first position hole 331.

[0076] When the antenna body 3 is attached, the first positioning hole 331 of the power supply part 33 is sleeved onto the first heat-melting pole 27 in advance to position the power supply part 33 in advance. Then, the position of the first heat-melting pole 27 that passes through the first positioning hole 331 is heat-melted using a mold to heat-melt and fix the power supply part 33 to the support rib 2. In this way, the first positioning hole 331 fits into the first heat-melting pole 27, ensuring the positional accuracy of the fit between the power supply part 33 and the support rib 2.

[0077] Optionally, to ensure the reliability of the connection between the mechanical component 1 and the support rib 2, the mechanical component 1 and the support rib 2 are integrally formed, i.e., each support rib 2 is integrally formed during the manufacture of the mechanical component 1 to ensure the reliability of the entire structure.

[0078] Optionally, the width dimension of the gap H formed between the support ribs 2 can be equal to or greater than the thickness dimension of the antenna body 3. In this way, the antenna body 3 can be easily clamped into the gap H, which facilitates the installation of the antenna body 3 and ensures the reliability of the clamping of the antenna body 3.

[0079] Specifically, the material of the support rib 2 may be, but is not limited to, plastic, glass, ceramic, etc. In this embodiment, plastic is preferably used. In one aspect, plastic can facilitate processing and production and is low cost. In another aspect, plastic is useful for implementing lightweight electronic devices.

[0080] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Those skilled in the art may have various modifications and variations to the present application. Any modifications, equivalent replacements, improvements, etc. made without departing from the spirit and principles of the present application shall also fall within the scope of protection of the present application.
