Description

Technical Field

[0001] The utility model relates to the technical field of automobile antennas, in particular to an antenna. Background Art

[0002] The car antenna generally comprises an antenna body and two upper and lower shells, wherein the antenna body is arranged in the lower shell. The shells of antenna products currently on the market are mainly connected by means of buckles or screws.

[0003] There are two disadvantages in the existing snap-on connection method: first, since the snaps have a certain degree of elasticity, a certain amount of elastic space will be reserved on both sides of the snaps. The existence of such elastic space will lead to poor sealing of the shell, which cannot meet the waterproof and dustproof requirements of the antenna product; second, the stability of the snap-on connection is poor. For example, when the antenna product is subject to vibration, falling, etc., the snap-on is easy to disengage, thereby destroying the dustproofness of the antenna product and affecting the quality of the antenna. Therefore, limiting ribs are usually added inside the shell to improve the stability of the snap-on connection. However, the limiting ribs will reduce the usable space of electronic components in the shell, increasing the difficulty of designing internal electronic components.

[0004] In addition, the existing screw connection method also has two disadvantages: first, the purchase and assembly of screws will increase the manufacturing cost, labor cost and time cost of the antenna product; second, compared with the snap connection method, the screw connection will increase the overall volume of the antenna product, which will easily increase the design difficulty when the application space is limited.

[0005] Based on this, how to achieve the dust and water resistance requirements of the antenna at a lower cost and design difficulty while ensuring that the inner cavity volume of the antenna is larger and the outer volume is smaller is a problem that needs to be solved urgently. Utility Model Content

[0006] The purpose of the utility model is to solve the technical problem that the existing connection method of the antenna shell cannot achieve dustproof and waterproof at a low cost. The utility model provides an antenna that can make the upper and lower shells fit tightly, thereby ensuring the sealing of the antenna and meeting certain dustproof and waterproof requirements. At the same time, the design difficulty of the antenna shell of the utility model is relatively low, the cost is low, and it does not occupy the use space of the shell cavity, nor does it increase the volume of the shell outside.

[0007] In order to solve the above technical problems, the embodiment of the utility model discloses an antenna, comprising:

[0008] A first shell, wherein the outer wall of the first shell is provided with a plurality of limiting grooves, and each of the limiting grooves is provided with a first clamping portion;

[0009] The second shell includes a bottom end facing the first shell along the first direction, and a plurality of second clamping parts are protruding from the bottom end, and the plurality of second clamping parts correspond one by one to the plurality of limiting grooves. Each of the second clamping parts is accommodated in the corresponding limiting groove and is clamped with the first clamping part in the corresponding limiting groove, so that the second shell is fitted with the second shell along the first direction to form a closed inner cavity.

[0010] By adopting the above technical solution, a plurality of limiting grooves are opened on the outer wall of the first shell (a first clamping portion is provided in each limiting groove), and a plurality of second clamping portions corresponding to the plurality of first clamping portions are provided on the end of the second shell facing the first shell, so that the second clamping portions can be accommodated in the corresponding limiting grooves and clamped with the corresponding first clamping portions, so that the two shells fit tightly.

[0011] Since the second clamping portion is arranged in the groove (limiting groove) of the outer wall of the first shell, and the first clamping portion is directly accommodated in the limiting groove and clamped with the second clamping portion, this arrangement effectively avoids the possibility of the existence of gaps, openings, and elastic spaces in the interconnected parts of the two shells, thereby effectively improving the connection strength and connection stability between the first shell and the second shell, allowing the first shell and the second shell to fit tightly, effectively improving the dustproof and waterproof performance of the antenna shell.

[0012] In addition, the first clamping portion and the second clamping portion of the embodiment of the present application will not be detached due to vibration or falling, and there is no need to add any parts for limiting inside or outside the shell (such as the above-mentioned limiting ribs), so it will not reduce the use space of the antenna electronic components or increase the overall size of the antenna, and will not increase unnecessary design difficulty due to connection problems between the shells; at the same time, the embodiment of the present application directly opens a limiting groove including the first clamping portion on the outer wall of the first shell, and the second clamping portion is accommodated in the limiting groove and clamped with the corresponding first clamping portion to achieve a tight connection between the two shells. The first clamping portion and the second clamping portion can be exemplarily made of plastic material. Therefore, compared with the existing screw connection, the cost of the antenna in the embodiment of the present application is lower.

[0013] According to another specific embodiment of the present invention, the first shell includes a plurality of outer walls, and each of the outer walls is provided with at least one limiting groove.

[0017] A first clamping groove is provided on one side of the first limiting rod along a third direction, the third direction is perpendicular to the second direction, and the first clamping groove is used to accommodate the first clamping hook so that the first clamping hook is clamped with the first clamping groove.

[0018] By adopting the above technical solution, the first hook of the first clamping part is directly integrally formed with one of the side walls of the first limiting groove. That is to say, after the second clamping part is accommodated in the first limiting groove, the first groove of the second clamping part can be directly clamped with the first hook. This connection form can effectively improve the connection strength between the first hook and the first groove, and prevent the first shell and the second shell from being detached due to external factors such as falling and vibration.

[0019] According to another specific embodiment of the utility model, the first limiting groove includes a first side wall and a second side wall, and the first side wall and the second side wall are spaced apart along the third direction; along the third direction, the other side of the first limiting rod facing away from the first locking groove is in contact with the first side wall, and the first hook is protruding on the second side wall.

[0020] According to another specific embodiment of the utility model, the first limiting groove further includes a first arc-shaped wall, the first hook includes a first fitting surface and a first abutting surface connected at an angle, and the first clamping groove includes a first inner wall and a second inner wall connected at an angle, wherein:

[0025] Along the fifth direction, a second slot is provided on a side of the second limiting rod facing the first slot, the fifth direction is perpendicular to the fourth direction, and the second slot is used to accommodate the second hook so that the second hook is engaged with the second slot.

[0026] By adopting the above technical solution, illustratively, by providing two groups of components for clamping (first limiting groove, second limiting groove; first hook, second hook; first limiting rod, second limiting rod), the connection strength between the first shell and the second shell can be further improved.

[0027] According to another specific embodiment of the present utility model, the second limiting groove includes a third side wall and a fourth side wall, and the third side wall and the fourth side wall are spaced apart along the fifth direction; along the fifth direction, the other side of the second limiting rod facing away from the second locking groove is in contact with the third side wall, and the second hook is protruding from the fourth side wall.

[0028] According to another specific embodiment of the utility model, the second limiting groove further includes a second arc-shaped wall, the second hook includes a second fitting surface and a second abutting surface connected at an angle, and the second clamping groove includes a third inner wall and a fourth inner wall connected at an angle, wherein:

[0030] According to another specific embodiment of the present invention, the first arc-shaped wall and the second arc-shaped wall are integrally formed into the same arc surface.

[0031] According to another specific implementation of the utility model, along the first direction, the first hook and the second hook are symmetrically arranged, and the first limiting rod and the second limiting rod are symmetrically arranged.

DETAILED DESCRIPTION

[0051] The following is an explanation of the implementation of the present invention by specific specific embodiments. Those skilled in the art can easily understand other advantages and functions of the present invention from the contents disclosed in this specification. Although the description of the present invention will be introduced in conjunction with the preferred embodiment, this does not mean that the features of this utility model are limited to this implementation. On the contrary, the purpose of introducing the utility model in conjunction with the implementation is to cover other options or modifications that may be extended based on the claims of the present invention. In order to provide a deep understanding of the present invention, the following description will include many specific details. The present invention can also be implemented without using these details. In addition, in order to avoid confusion or blurring the focus of the present invention, some specific details will be omitted in the description. It should be noted that, in the absence of conflict, the embodiments in the present invention and the features in the embodiments can be combined with each other.

[0052] It should be noted that in this specification, similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined and explained in the subsequent drawings.

[0053] In the description of this embodiment, it should be noted that the terms "upper", "lower", "inner", "bottom", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, or are the orientations or positional relationships in which the utility model product is usually placed when in use. They are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the utility model.

[0054] The terms “first”, “second”, etc. are only used for distinguishing descriptions and should not be understood as indicating or implying relative importance.

[0055] In the description of this embodiment, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this embodiment can be understood according to specific circumstances.

[0056] In order to make the purpose, technical solution and advantages of the present invention more clear, the implementation mode of the present invention will be further described in detail below with reference to the accompanying drawings.

[0057] The antenna usually includes a shell and an antenna body arranged in the shell. The antenna body includes electronic components (such as a driver, a controller, etc.) connected to a printed circuit board. Therefore, in order to meet the requirements of the use environment, the antenna shell needs to be able to prevent dust, water and other debris from entering the cavity inside the shell to avoid causing short circuits and the like.

[0058] At present, common connection methods for antenna housings mainly include snap-on connection and screw connection, but these two connection methods cannot balance the characteristics of high connection stability, waterproof and dustproof, and low cost (low design cost, low procurement cost, and low time cost). The embodiment of the present application is described by taking a car antenna as an example, and the antenna of the embodiment of the present application is not limited to this.

[0059] See also Figure 1a and Figure 1b , Figure 1a A perspective view of an antenna 100 is shown. Figure 1b An exploded view of an antenna 100 is shown. The antenna 100 includes an upper shell 110 and a lower shell 120 , and the upper shell 110 and the lower shell 120 are connected by a buckle 130 .

[0060] like Figure 1a As shown, the buckle 130 is usually made of elastic material. Therefore, a certain elastic space 140 needs to be left around each buckle 130. The elastic space 140 will affect the axial direction between the upper shell 110 and the lower shell 120 (such as Figure 1a a direction shown in the figure) and transverse direction (as shown in the figure) Figure 1a That is, the elastic space 140 will cause the interior of the antenna 100 to no longer be a closed space, so that external impurities (such as water, dust, etc.) will enter the interior of the antenna 100 through the elastic space 140, making the antenna 100 unable to meet the dust and water resistance requirements.

[0061] In addition, if Figure 1b As shown, since the buckle 130 has elastic characteristics, when the antenna 100 encounters a fall, vibration, etc., the buckle 130 is easy to move along the Figure 1b The c direction shown in FIG. 1 is disengaged. For example, a car antenna is particularly frequently subjected to vibration. Therefore, in this case, the electronic components inside the lower housing 120 are easily damaged.

[0062] In order to prevent the buckle 130 from being disengaged, a plurality of limiting ribs 150 are often added inside the housing (for example, inside the upper housing 110). The limiting ribs 150 are used to adjust the upper housing 110 and the lower housing 120. Figure 1b The setting of the limiting rib 150 reduces the available space of the inner cavity of the housing and increases the difficulty of arranging the electronic components.

[0063] See also Figure 1c , Figure 1c A stereoscopic diagram of an antenna 200 is shown. The antenna 200 includes an upper shell 210 and a lower shell 220. The upper shell 210 and the lower shell 220 are connected by screws 230. Eight screws 230 are shown by way of example in the figure, but this application does not limit this.

[0064] The screws 230 are used to connect the upper shell 210 and the lower shell 220. It is necessary to set an upper screw connection part 2100 at the corresponding position of the upper shell 210 and a lower screw connection part 2200 at the corresponding position of the lower shell 220. The upper screw connection part 2100 and the lower screw connection part 2200 need to be formed by a certain molding process (such as injection molding), which invisibly increases the manufacturing cost.

[0065] At the same time, the price of the screw 230 itself is relatively high, which will increase the purchase cost to a certain extent, and the assembly process of the screw 230 is time-consuming and labor-intensive. Figure 1a The antenna 100 and the antenna 200 shown in the figure also increase the overall volume due to the screws 230. If the application space (such as in a car) is limited, the design difficulty of the antenna 200 will be further increased.

[0066] To solve the above existing problems, see Figure 2 The embodiment of the present application further provides an antenna 1, comprising a first shell 10 and a second shell 20.

[0067] See also Figure 3 and Figure 4 , Figure 3 The perspective view of the first housing 10 is shown as an example. Figure 4 A perspective view of the second housing 20 is shown as an example.

[0068] The first shell 10 is a rectangular parallelepiped structure including four outer walls 1000, but the embodiment of the present application does not limit the shape of the first shell 10 and the number of outer walls 1000, that is, the first shell 10 can also be rectangular, cylindrical, etc. The first shell 10 can include one outer wall (closed), five outer walls, seven outer walls, etc. The embodiment of the present application takes the first shell 10 and the second shell 20 to be described later as a rectangular parallelepiped (including four outer walls 1000) as an example for explanation.

[0069] It can be seen that each outer wall 1000 of the first housing 10 is provided with a limiting groove 101. Figure 3 The two outer walls 1000 indicated by the X direction are respectively provided with three limiting grooves 101. Figure 3 A limiting groove 101 is respectively formed on the two outer walls 1000 indicated by the Y direction. Figure 3The eight limiting grooves 101 exemplarily shown in the figure are all provided with a first clamping portion 102 .

[0070] For example, Figure 3 The three limiting grooves 101 in the outer wall 1000 indicated by the X1 direction are arranged at intervals along the Y direction. Figure 3 The three limiting grooves 101 in the outer wall 1000 indicated by the X2 direction are also arranged at intervals along the Y direction. Exemplarily, the three limiting grooves 101 of the outer wall 1000 indicated by the X1 direction and the three limiting grooves 101 of the outer wall 1000 indicated by the X2 direction correspond one to one along the X direction, but the embodiment of the present application does not limit this, that is, along the X direction, the three limiting grooves 101 of the outer wall 1000 indicated by the X1 direction and the three limiting grooves 101 of the outer wall 1000 indicated by the X2 direction may not correspond (i.e., staggered along the Y direction).

[0071] Accordingly, exemplarily, along the Y direction, Figure 3 The limiting groove 101 in the outer wall 1000 indicated in the Y1 direction and the limiting groove 101 in the outer wall 1000 indicated in the Y2 direction also correspond one to one, and the embodiment of the present application does not impose any limitation on this. That is, along the Y direction, the limiting groove 101 of the outer wall 1000 indicated in the Y1 direction and the limiting groove 101 of the outer wall 1000 indicated in the Y2 direction may not correspond (that is, they are offset along the X direction).

[0072] It should be noted that the embodiment of the present application does not limit the number of the limiting grooves 101 provided on each outer wall 1000 and the corresponding relationship between the limiting grooves 101 of two corresponding outer walls 1000. For example, Figure 3 The two outer walls 1000 indicated by the X direction may also be provided with four, six, or seven limiting grooves 101, respectively. Figure 3 The two outer walls 1000 indicated by the Y direction may also be provided with two, three or four limiting grooves 101 respectively.

[0073] See also Figure 3 and Figure 4 Combined with Figure 2 , along the first direction (such as Figure 4 The second housing 20 includes a bottom end 201 facing the first housing 10, and the number and position of the bottom end 201 correspond to the outer wall 1000 described above. Figure 4 Four bottom ends 201 are exemplarily shown in the figure, and each bottom end 201 is provided with a second clamping portion 202 protruding therefrom.

[0074] Exemplarily, the number and arrangement of the second clamping portions 202 of each bottom end 201 correspond one-to-one to the above-mentioned limiting grooves 101. This document does not elaborate on possible implementation methods of the second clamping portions 202, and refers to the above-mentioned exemplary description of the limiting grooves 101.

[0075] See also Figure 2 Each second clamping portion 202 is accommodated in the corresponding limiting groove 101 and is clamped with the first clamping portion 102 in the corresponding limiting groove 101, so that the second housing 20 is moved in the first direction (such as Figure 2 The Z direction shown in FIG. 1 is fitted with the second shell 20 to form a closed inner cavity.

[0076] Using the above technical solution, see Figures 2 to 4 A plurality of limiting grooves 101 (a first clamping portion 102 is provided in each limiting groove 101) are provided on the outer wall 1000 of the first shell 10, and a plurality of second clamping portions 202 corresponding to the plurality of first clamping portions 102 are provided on one end of the second shell 20 facing the first shell 10, so that the second clamping portions 202 can be accommodated in the corresponding limiting grooves 101 and clamped with the corresponding first clamping portions 102, so that the two shells fit tightly.

[0077] Since the second clamping portion 202 is arranged in the groove (limiting groove 101) of the outer wall of the first shell 10, and the first clamping portion 102 is directly accommodated in the limiting groove 101 and clamped with the second clamping portion 202, this arrangement effectively avoids the possibility of the existence of gaps, openings, and elastic spaces in the interconnected parts between the two shells, thereby effectively improving the connection strength and connection stability between the first shell 10 and the second shell 20, so that the first shell 10 and the second shell 20 can fit tightly, effectively improving the dustproof and waterproof performance of the antenna 1 shell.

[0078] In addition, the first clamping portion 102 and the second clamping portion 202 of the embodiment of the present application will not come apart due to vibration or falling, and there is no need to add any parts for limiting the position (such as the above-mentioned limiting ribs) inside or outside the shell. Therefore, the use space of the electronic components of the antenna 1 will not be reduced or the overall size of the antenna 1 will not be increased, and unnecessary design difficulty will not be increased due to connection problems between the shells. At the same time, compared with the existing screw connection, the cost of the antenna 1 in the embodiment of the present application is lower.

[0079] In one possible implementation, see Figure 3 and Figure 4 Combined with Figure 2 The limiting groove 101 includes a first limiting groove 1011, and the first clamping portion 102 includes a first hook 1021 (such as Figure 3 As shown), the second clamping portion 202 includes a first limiting rod 2021 (as shown Figure 4 shown).

[0080] The first limiting rod 2021 is received in the first limiting groove 1011 and extends along the second direction (eg Figure 2 and Figure 4The second direction (as shown in the E direction) extends. Figure 2 E direction shown in FIG) and the first direction (as shown in FIG Figure 2 The Z direction shown in FIG. 1 intersects at an angle.

[0081] See also Figure 5a and Figure 5b , Figure 5a and Figure 5b Partially enlarged views of the limiting groove 101 at different viewing angles are shown respectively.

[0082] The first limiting groove 1011 includes a first bottom wall 10111 and two side walls (i.e., a first side wall 10112 and a second side wall 10113 to be described later). Figure 5a The first hook 1021 is integrally formed with the first bottom wall 10111 along the second direction (eg, Figure 2 E direction shown in FIG.

[0083] See also Figure 5a and Figure 5b Combined with Figure 2 The embodiment of the present application does not limit the number of side walls of the first limiting groove 1011. The first limiting groove 1011 may also include three, four, or six side walls, that is, the shape of the contour of the first limiting groove 1011 is not limited and may be an irregular shape. As long as it can limit the first limiting rod 2021 and is provided with a first hook 1021 so that the first hook 1021 and the first limiting rod 2021 can be connected, it belongs to the protection scope of the embodiment of the present application.

[0084] See also Figure 6a and Figure 6b , Figure 6a and Figure 6b The partial enlarged views of the second clamping portion at different viewing angles are shown respectively. Figure 6a and Figure 6b E direction shown in FIG), one end of the first limiting rod 2021 (ie Figure 6a and Figure 6b The end indicated by the direction E1 in the figure is connected to the bottom end 201 of the second shell 20.

[0085] See also Figure 7 , Figure 7 A partial enlarged view of the limiting groove 101 , the first clamping portion 102 and the second clamping portion 202 is shown.

The second limiting groove 1012 may also include three, four, or six side walls, that is, the shape of the contour of the second limiting groove 1012 is not limited and may be an irregular shape. As long as it can limit the second limiting rod 2022 and is provided with a second hook 1022 so that the second hook 1022 and the second limiting rod 2022 can be connected, it belongs to the protection scope of the embodiment of the present application.

Figure 5b ) and a fourth inner wall 202212 (as shown) of a portion of the second slot 20221 Figure 6b shown) combined.

[0111] As can be seen from the foregoing, the second hook 1022 is protruded from the fourth side wall 10123 of the second limiting groove 1012. For example, see Figure 5a and Figure 5b The second arc-shaped wall 10124 of the second limiting groove 1012 and the second fitting surface 10221 are connected to form the same arc surface.

[0112] In one possible implementation, see Figure 5b , the first arcuate wall 10114 and the second arcuate wall 10124 are integrally formed into the same arc surface. Figure 5a and Figure 5b The first arcuate wall 10114, the second arcuate wall 10124, the first fitting surface 10211 and the second fitting surface 10221 are integrally formed into the same arcuate surface.

[0113] See also Figure 7 Based on this and in combination with the above description (i.e., the first limiting groove 1011 and the second limiting groove 1012 are symmetrically arranged relative to the first direction), illustratively, the first limiting rod 2021 and the second limiting rod 2022 are arranged along the first direction (e.g. Figure 7 The Z direction shown in FIG. 2 is symmetrically arranged.

[0114] For example, see Figure 7 The first hook 1021 and the second hook 1022 are arranged along a first direction (eg Figure 7 The first limiting groove 1011 and the second limiting groove 1012 are arranged symmetrically along the first direction (as shown in the Z direction). Figure 7 The Z direction shown in FIG. 2 is symmetrically arranged.

[0115] Exemplarily, the first limiting rod 2021 and the second limiting rod 2022 are in an eight-shaped shape, but the present application does not limit the shapes of the first limiting rod 2021 and the second limiting rod 2022. In other words, the extension direction (E direction) of the first limiting rod 2021 and the extension direction (G direction) of the second limiting rod 2022 may not be symmetrically arranged along the first direction (Z direction).

[0116] In one possible implementation, see Figure 7 The first limiting rod 2021 and the second limiting rod 2022 are made of elastic material (such as plastic). Figure 7The end indicated by the direction E2 in the middle is the first arc-shaped end 20213, that is, along the second direction (such as Figure 7 The first arc-shaped end 20213 is away from the bottom end 201 of the second housing 20. The first arc-shaped end 20213 and the first limiting rod 2021 are in the third direction (as shown in FIG. Figure 7 The first locking groove 20211 and the first arc-shaped end 20213 of the first limiting rod 2021 are arranged at intervals.

[0117] Continue reading Figure 7 The end of the second limiting rod 2022 spaced apart from the second bottom wall 10121 is a second arc-shaped end 20223, that is, along the fourth direction (such as Figure 7 The second arc-shaped end 20223 is away from the bottom end 201 of the second housing 20. The second arc-shaped end 20223 is connected to two side surfaces of the second limiting rod 2022 along the fifth direction (the H direction shown in FIG. 7 ), and the second slot 20221 of the second limiting rod 2022 and the second arc-shaped end 20223 are spaced apart.

[0118] For example, see Figure 7 Combined with Figure 3 , along the length direction of the outer wall 1000 of the first shell 10 (such as Figure 3 In the Y direction shown in FIG, the first card slot 20211 and the second card slot 20221 are arranged opposite to each other, and the first card hook 1021 and the second card hook 1022 are arranged opposite to each other.

[0119] For example, see Figures 2 to 7 According to the above description, the first arcuate wall 10114, the second arcuate wall 10124, the first fitting surface 10211 and the second fitting surface 10221 are integrally formed into the same arcuate surface. That is, when installing, the second housing 20 is moved along the first direction (such as Figure 2 The first arc-shaped end 20213 of the first limiting rod 2021 can move along the arc surface of the first arc-shaped wall 10114 and the first fitting surface 10211 (along the arc surface of the first arc-shaped wall 10114 and the first fitting surface 10211). Figure 7 The first locking groove 20211 of the first limiting rod 2021 is engaged with the first hook 1021; accordingly, at the same time, the second arc-shaped end 20223 of the second limiting rod 2022 can also move along the arc surface of the second arc wall 10124 and the second fitting surface 10221 (along the arc surface of the second arc wall 10124 and the second fitting surface 10221). Figure 7 The second locking groove 20221 of the second limiting rod 2022 is engaged with the second hook 1022.

[0120] In one possible implementation, see Figure 7The second clamping portion 202 further includes a connecting portion 2023, which is arranged along the length direction of the outer wall of the first shell (for example, Figure 3 The connecting portion 2023 and the bottom end 201 of the second housing 20 are integrally formed, and the end of the first limiting rod 2021 away from the first slot 20211 along the second direction (i.e. Figure 7 The end indicated by the direction E1 in the middle) is integrally formed on one side of the connecting portion 2023 (i.e. Figure 7 Accordingly, the end of the second limiting rod 2022 away from the second slot 20221 along the second direction (i.e. Figure 7 The end indicated by the direction G1 in the middle) is integrally formed on the other side of the connecting portion 2023 (i.e. Figure 7 The side indicated by the Y2 direction in the figure).

[0121] For example, see Figure 7 Combined with Figure 5b The first limiting rod 2021 has a side surface (i.e. Figure 7 The side indicated by the F2 direction in the figure), the side of the second limiting rod 2022 provided with the second slot 20221 along the fifth direction (ie Figure 7 The side indicated by the direction H1 in the middle), the first arc-shaped wall 10114 and the second arc-shaped wall 10124, and the bottom surface of the connecting portion 2023 along the first direction (ie Figure 7 The side indicated by the Z2 direction in the middle) together form a cavity S.

[0122] By adopting the above technical scheme, the first limiting rod 2021 and the second limiting rod 2022 are respectively connected to the connecting part 2023 to be integrally formed with the second shell 20. The first limiting rod 2021, the second limiting rod 2022, the connecting part 2023, the first arcuate wall 10114 and the second arcuate wall 10124 together form a cavity S. The cavity S can reduce the weight of the first shell 10, making the antenna 1 product lighter and reducing the material cost of the first shell 10.
