Description

Technical Field

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

[0002] Automobile antennas usually include an antenna body and two upper and lower shells, with the antenna body being arranged in the lower shell. In order to facilitate the assembly between the upper and lower shells, a positioning structure is usually arranged in the inner cavity of the shell. On the one hand, this requires that the shell has sufficient internal space to arrange the positioning structure. However, as electronic components tend to be miniaturized, the volume of the antenna shell is also reduced. Therefore, when the internal space of the shell is insufficient, the positioning structure is difficult to arrange, thus affecting the assembly of the antenna shell. On the other hand, the operator cannot clearly observe whether the positioning structure in the inner cavity is assembled in place. Utility Model Content

[0003] The purpose of the utility model is to solve the technical problem that the traditional antenna housing positioning structure occupies the internal space of the housing. The utility model provides a housing and an antenna for an antenna. The positioning convex part and the positioning concave part of the housing in the embodiment of the application are not affected by the housing accommodating cavity, and the internal space of the housing is effectively saved. At the same time, it can be judged whether the housing is assembled in place by naked eye observation, which improves the positioning and assembly effect and efficiency of the housing.

[0004] In order to solve the above technical problems, the embodiment of the utility model discloses a housing for an antenna, comprising:

[0005] A first shell, along a first direction, the first shell comprises a plurality of first top walls, at least one of the plurality of first top walls being provided with at least one positioning protrusion;

[0006] A second shell, the second shell and the first shell jointly define a accommodating cavity, and the accommodating cavity is used to accommodate the antenna body; along the first direction, the second shell includes a plurality of first bottom walls facing the first shell, at least one of the plurality of first bottom walls is provided with at least one positioning recess, the at least one positioning recess corresponds one-to-one with the at least one positioning protrusion, and the concave-convex fits along the first direction; the at least one positioning protrusion is located outside the accommodating cavity.

[0007] In the traditional antenna housing positioning scheme, positioning structures are usually set inside the upper housing and the lower housing respectively. For example, positioning ribs are set on the inner wall of the upper housing, and the positioning ribs and the inner wall of the upper housing form a groove, and then abut against the lower housing, so as to achieve the positioning between the upper housing and the lower housing. However, the inner cavity formed by the upper and lower housings is used to install printed circuit boards and various electronic components. When the inner cavity space is insufficient, it is difficult to set the positioning structure.

[0008] By adopting the above technical solution, one or more positioning protrusions are arranged on at least one first top wall of the first shell, and at the same time, corresponding positioning recesses are arranged on the first bottom wall of the second shell corresponding to the first top wall. The positioning protrusions and the positioning recesses are matched with each other, so that effective positioning between the first shell and the second shell can be achieved.

[0009] That is, the positioning protrusion is set on the first shell, and the corresponding positioning concave is set on the second shell. Then the positioning protrusion and positioning concave of the present application are located outside the accommodating cavity, which avoids the problem that the positioning structure cannot be effectively set due to insufficient inner cavity space in the traditional way. At the same time, the positioning and assembly process of the first shell and the second shell can be observed by naked eyes, which is convenient for operators to judge whether the assembly is in place, thereby improving the positioning and assembly effect and efficiency between the first shell and the second shell.

[0010] According to another specific embodiment of the utility model, the multiple first top walls include four, and the four first top walls form a rectangular opening; along the second direction, two of the four first top walls are arranged opposite to each other, and the two first top walls are respectively provided with two of the positioning protrusions; along the third direction, the other two of the four first top walls are arranged opposite to each other, one of the other two first top walls is provided with two of the positioning protrusions, and the other of the other two first top walls is provided with one of the positioning protrusions; the second direction, the third direction, and the first direction are perpendicular to each other.

[0011] According to another specific embodiment of the utility model, the first bottom walls include four first bottom walls, and the four first bottom walls form a rectangular opening; along the second direction, two of the four first bottom walls are arranged opposite to each other, and the two first bottom walls are respectively provided with two of the positioning recesses; along the third direction, the other two of the four first bottom walls are arranged opposite to each other, one of the other two first bottom walls is provided with two of the positioning recesses, and the other of the other two first bottom walls is provided with one of the positioning recesses.

[0012] According to another specific embodiment of the utility model, each of the positioning recesses includes a first part and a second part that are connected, and along the first direction, the first part is located at an end away from the first shell, the second part is located at an end close to the first shell, and the second part tapers toward the first part along the first direction.

[0013] According to another specific embodiment of the present invention, along the length direction of the corresponding first bottom wall, the length of the first portion is greater than or equal to the length of the corresponding positioning protrusion, and the length of the second portion is greater than the length of the corresponding positioning protrusion.

[0014] By adopting the above technical solution, the length of the first part is greater than the length of the corresponding positioning protrusion, and the length of the second part is greater than the length of the corresponding positioning protrusion, so that an assembly gap can be provided for the positioning protrusion, which is convenient for the positioning protrusion to be accommodated. At the same time, during the positioning process, the positioning protrusion and the inner wall of the first part and the inner wall of the second part will not generate a large friction force, thereby reducing the wear between the positioning protrusion and the positioning concave part, and effectively improving the service life of the two; moreover, the first part reserves an assembly gap to facilitate the adjustment between the positioning protrusion and the positioning protrusion. When the length of the first part is equal to the length of the corresponding positioning protrusion, the positioning accuracy between the positioning concave part and the positioning protrusion can be effectively improved.

[0015] According to another specific embodiment of the present invention, the second shell is provided with a plurality of elastic clips, and at least two of the plurality of first bottom walls are respectively provided with at least one elastic clip, and the plurality of elastic clips are used to elastically abut against the outer wall of the first shell to limit the movement of the first shell and the second shell along the first direction.

[0016] According to another specific embodiment of the present utility model, the first shell includes a plurality of outer walls, which define the side periphery of the first shell. The first shell also includes a plurality of limiting protrusions, at least two of the plurality of outer walls are respectively provided with at least one limiting protrusion, the plurality of limiting protrusions correspond one-to-one with the plurality of elastic buckles, and the plurality of elastic buckles abut against the corresponding plurality of limiting protrusions.

[0017] By adopting the above technical solution, a plurality of elastic buckles provided on the second shell can abut against corresponding limiting protrusions provided on the first shell, so that the first shell and the second shell can be elastically connected with better connection stability.

[0018] According to another specific embodiment of the utility model, the multiple outer walls include a first outer wall, a second outer wall, a third outer wall and a fourth outer wall. Along the second direction, the first outer wall and the second outer wall are arranged opposite to each other, the first outer wall is provided with one limiting protrusion, and the second outer wall is provided with two limiting protrusions; along the third direction, the third outer wall and the fourth outer wall are arranged opposite to each other, and the third outer wall is provided with one limiting protrusion; the second direction, the third direction and the first direction are perpendicular to each other.

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.

[0036] 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.

[0037] 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.

[0038] The terms “first”, “second”, etc. are only used for distinguishing descriptions and should not be understood as indicating or implying relative importance.

[0039] 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.

[0040] 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.

[0041] refer to Figure 1 , Figure 1The antenna 100 in some embodiments is exemplarily shown. It can be seen that the antenna 100 includes an upper shell 110, a lower shell 120 and an antenna body 130. The antenna body 130 includes electronic components (such as a driver, a controller, etc.) connected to a printed circuit board.

[0042] Generally, when assembling the antenna 100, a positioning structure (such as Figure 1 The positioning ribs 111 and flanges 121 shown in the middle A area are provided to facilitate the assembly between the two shells. Figure 1 The positioning structure shown is arranged in the inner cavity 1000 of the upper housing 100, as shown in FIG. Figure 1 As shown, a positioning rib 111 is provided inside the upper shell 110, and a groove 112 is formed between the positioning rib 111 and the inner wall of the upper shell 110. During assembly, a flange 121 at the top wall of the lower shell 120 can abut against the groove 112, thereby achieving positioning between the upper shell 110 and the lower shell 120.

[0043] However, the antenna 100 currently tends to be miniaturized. In actual applications, the volumes of the upper shell 110, the lower shell 120 and the antenna body 130 will be greatly reduced. In this case, the remaining space in the inner cavity 1000 is insufficient, and it is difficult to further set the positioning ribs 111, so the positioning effect during the assembly of the upper shell 110 and the lower shell 120 cannot be achieved.

[0044] At the same time, the positioning rib 111 is arranged in the inner cavity 1000. Therefore, during the actual assembly process, it is difficult for the operator to clearly observe whether the flange 121 of the lower shell 120 is successfully abutted against the groove 112 of the positioning rib 111, that is, it is impossible to accurately judge whether the assembly is in place.

[0045] Based on this, reference Figures 2 to 4 An embodiment of the present application provides an antenna 1 , which includes a shell 2 and an antenna body 3 located inside the shell 2 .

[0046] The housing 2 includes a first housing 10 and a second housing 20. Figure 2 As shown, a first inner cavity 501 is formed inside the first shell 10, and a second inner cavity 502 is formed inside the second shell 20. After the first shell 10 and the second shell 20 are assembled, the first inner cavity 501 and the second inner cavity 502 can jointly define a accommodating cavity 50, which is also the inner cavity of the shell 2.

[0047] The antenna body 3 includes a circuit board 31 (such as a PCB printed circuit board) and an electronic component 32 electrically connected to the circuit board 31. By way of example, the antenna body 3 is assembled into the first shell 10. When the second shell 20 is further assembled with the first shell 10, the antenna body 3 is accommodated in the above-mentioned accommodation cavity 50 of the shell 2.

[0048] The positioning structure of the housing 2 in the embodiment of the present application is respectively arranged on the first housing 10 and the second housing 20 , but is not located in the accommodating cavity 50 .

[0049] Specifically, refer to Figure 5 and Figure 6 , Figure 5 The perspective view of the first housing 10 in the housing of the embodiment of the present application is exemplarily shown; Figure 6 A three-dimensional view of the second shell 20 in the shell of the embodiment of the present application is exemplarily shown.

[0050] like Figure 5 As shown, along the first direction (such as Figure 5 The first housing 10 includes four first top walls 101. Figure 5 Four first top walls 101 are shown as an example, but the embodiment of the present application does not limit the number of the first top walls 101. For example, three, five, six, etc. first top walls 101 may also be provided.

[0051] Exemplarily, the four first top walls 101 form a rectangular opening. The embodiment of the present application does not specifically limit the shape of the first top walls 101. For example, the four first top walls 101 may also form a parallelogram, a trapezoid or other irregular shapes.

[0052] It can be seen that one or more positioning protrusions 30 are respectively provided in the four first top walls 101. Figure 5 In the X direction shown in FIG), two of the four first top walls 101 are arranged opposite to each other, and the two first top walls 101 are respectively provided with two positioning protrusions 30, that is, Figure 5 The first top wall 101 indicated by the X1 direction is provided with two positioning protrusions 30 , and the first top wall 101 indicated by the X2 direction is also provided with two positioning protrusions 30 .

[0053] Along the third direction (such as Figure 5 The other two first top walls 101 of the four first top walls 101 are also arranged opposite to each other, and one of the other two first top walls 101 (i.e. Figure 5 The other first top wall 101 (ie, the other first top wall 101) is provided with two positioning protrusions 30. Figure 5A positioning protrusion 30 is provided (indicated by the Y2 direction).

[0054] In some other possible implementations, the positioning protrusion 30 may be provided on any one or more of the above-mentioned first top walls 101. That is, only one positioning protrusion 30 may be provided on one of the first top walls 101, or two, three, or the like positioning protrusions 30 may be provided on one of the first top walls 101; or, one positioning protrusion 30 may be provided on any two, three, or four of the first top walls 101, or two, three, or four, or the like positioning protrusions 30 may be provided on any two, three, or four of the first top walls 101, respectively. The embodiment of the present application does not specifically limit the above-mentioned arrangement of the positioning protrusion 30.

[0055] like Figure 6 As shown, along the first direction (such as Figure 6 The second housing 20 includes four first bottom walls 201 facing the first housing 10. Figure 6 Four first bottom walls 201 are shown as an example, but the embodiment of the present application does not limit the number of the first bottom walls 201. For example, three, five, six, etc. first bottom walls 201 may be provided.

[0056] Exemplarily, the four first bottom walls 201 form a rectangular opening. The embodiment of the present application does not specifically limit the shape of the first bottom walls 201. For example, the four first bottom walls 201 may also form a parallelogram, a trapezoid or other irregular shapes.

[0057] like Figure 6 As shown, it can be seen that one or more positioning recesses 40 are respectively provided in the four first bottom walls 201, and the positioning recesses 40 on the first bottom walls 201 correspond one to one with the positioning protrusions 30 on the first top wall 101. Figure 6 In the X direction shown in FIG), two of the four first bottom walls 201 are arranged opposite to each other, and the two first bottom walls 201 are respectively provided with two positioning recesses 40, that is, Figure 6 The first bottom wall 201 indicated by the X1 direction is provided with two positioning recesses 40. Figure 5 The two positioning protrusions 30 of the first top wall 101 indicated by the X1 direction correspond to each other one by one. Figure 6 The first bottom wall 201 indicated by the X2 direction is also provided with two positioning recesses 40. Figure 5 The two positioning protrusions 30 of the first top wall 101 indicated by the X2 direction correspond to each other one by one.

[0058] Along the third direction (such as Figure 6The other two first bottom walls 201 of the four first bottom walls 201 are also arranged opposite to each other, and one of the other two first bottom walls 201 (i.e. Figure 6 There are two positioning recesses 40, which are respectively provided in the direction of Y1. Figure 5 The two positioning protrusions 30 on the first top wall 101 indicated by the Y1 direction correspond to each other. Figure 6 A positioning recess 40 is provided, and the positioning recess 40 is aligned with the Figure 5 The Y2 direction corresponds to a positioning protrusion 30 on the first top wall 101.

[0059] In some other possible implementations, similar to the above-mentioned positioning protrusion 30, the positioning recess 40 can be arranged on any one or more of the above-mentioned first bottom walls 201. That is to say, only one positioning recess 40 can be arranged on one of the first bottom walls 201, or two, three, or the like positioning recesses 40 can be arranged on only one of the first bottom walls 201; or, one positioning recess 40 can be arranged on any two, three, or four of the first bottom walls 201, or two, three, or four, or the like positioning recesses 40 can be arranged on any two, three, or four of the first bottom walls 201, and the present embodiment of the application does not specifically limit the above-mentioned arrangement of the positioning recess 40.

[0060] For example, the first direction (eg Figure 5 and Figure 6 The Z direction shown in FIG. 1 ), the second direction (such as Figure 5 and Figure 6 The X direction shown in FIG), the third direction (such as Figure 5 and Figure 6 The Y direction shown in FIG. 2 is perpendicular to each other.

[0061] Refer to Figures 7 to 10 Combined with the above, Figure 7 The front view of the housing of the embodiment of the present application is exemplarily shown. Figure 7 It is shown that Figure 5 and Figure 6 The side pointed by the X1 direction. Figure 8 The rear view of the housing of the embodiment of the present application is shown exemplarily. Figure 8 It is shown that Figure 5 and Figure 6 The side pointed by the X2 direction. Fig. 9 The left side view of the housing of the embodiment of the present application is shown as an example. Fig. 9 It is shown that Figure 5 and Figure 6 The side indicated by the Y2 direction. Fig.10 The right side view of the housing of the embodiment of the present application is shown as an example. Fig.10 It is shown that Figure 5 and Figure 6 The side pointed by the Y1 direction.

[0062] refer to Fig.11 and Fig.12 Combined with Figure 2 and Figure 3 It can be seen that the positioning protrusion 30 provided at the first top wall 101 of the first shell 10 and the positioning recess 40 provided at the first bottom wall 201 of the second shell 20 cooperate with each other, so that the positioning and assembly between the first shell 10 and the second shell 20 can be achieved. The assembled shell 2 is as shown in FIG. Figure 3 and Figure 4 As shown, it can be seen that after the concave and convex parts are matched, the positioning protrusion 30 is located outside the accommodating cavity 50.

[0063] refer to Figures 3 to 6 Combined with Figure 2 By adopting the above technical solution, one or more positioning protrusions 30 are provided on at least one first top wall 101 of the first shell 10. At the same time, corresponding positioning recesses 40 are provided on the first bottom wall 201 of the second shell 20 corresponding to the first top wall 101. The positioning protrusions 30 and the positioning recesses 40 are matched with each other, so that effective positioning between the first shell 10 and the second shell 20 can be achieved.

[0064] That is, the positioning protrusion 30 is set on the first shell 10, and the corresponding positioning recess 40 is set on the second shell 20. Then the positioning protrusion 30 and the positioning recess 40 of the present application are located outside the accommodating cavity 50, avoiding the problem that the positioning structure cannot be effectively set due to insufficient inner cavity space in the traditional way. At the same time, the positioning and assembly process of the first shell 10 and the second shell 20 can be observed by naked eyes, which is convenient for operators to judge whether the assembly is in place, thereby improving the positioning and assembly effect and efficiency between the first shell 10 and the second shell 20.

[0065] refer to Fig.13 Combined with Figure 7 In a possible implementation manner, each of the above-mentioned positioning recesses 40 includes a first portion 401 and a second portion 402 that are connected to each other, along a first direction (such as Fig.13 The first portion 401 is located at one end away from the first housing 10 (ie, Fig.13 The second portion 402 is located near one end of the first housing 10 (ie Fig.13), it can be seen that the first part 401 is rectangular, the second part 402 is trumpet-shaped, and the second part 402 tapers along the first direction toward the first part 401. However, the embodiment of the present application does not limit the shapes of the first part 401 and the second part 402. For example, the first part 401 can also be set to a square, trapezoidal or other shapes, and the second part 402 can also be set to a rectangle, square or other shapes. As long as the positioning concave part 40 can be accommodated by the above-mentioned positioning convex part, the shape belongs to the protection scope of the embodiment of the present application.

[0066] refer to Fig.12 and Fig.13 In a possible implementation, along the length direction of the corresponding first bottom wall, the length L1 of the first portion 401 is greater than the length L3 of the corresponding positioning protrusion 30, and the length L2 of the second portion 402 is greater than the length L3 of the corresponding positioning protrusion 30. It should be noted that the length direction of the corresponding first bottom wall may be the second direction (such as Fig. 9 and Fig.10 The X direction shown in FIG. 1 may also be the third direction (such as Figure 7 and Figure 8 Y direction shown in FIG.

[0067] refer to Figures 12 to 15 By adopting the above technical solution, the length L1 of the first part 401 is greater than the length L3 of the corresponding positioning protrusion 30, and the length L2 of the second part 402 is greater than the length L3 of the corresponding positioning protrusion 30, so that an assembly gap can be provided for the positioning protrusion 30 to facilitate the accommodation of the positioning protrusion 30.

[0068] At the same time, during the positioning process, the positioning protrusion 30 and the inner wall of the first part 401 (such as Fig.14 The first inner wall 4011 shown, Fig.15 The second inner wall 4012 shown in FIG. 1 ), and the inner wall of the positioning protrusion 30 and the second part 402 (as shown in FIG. Fig.14 The first inner wall 4021 shown, Fig.15 The second inner wall 4022 shown in the figure will not generate a large friction force, reducing the wear between the positioning protrusion 30 and the positioning recess 40, and effectively improving the service life of both. In addition, the first part 401 reserves an assembly gap to facilitate adjustment with the positioning protrusion 30.

[0069] In another possible implementation, along the length direction of the corresponding first bottom wall, the length L1 of the first portion 401 is equal to the length L3 of the corresponding positioning protrusion 30 .

[0070] By adopting the above technical solution, when the length L1 of the first portion 401 is equal to the length L3 of the corresponding positioning protrusion 30 , the positioning accuracy between the positioning recess 40 and the positioning protrusion 30 can be effectively improved.

[0071] In one possible implementation, reference Figure 3 and Figure 4 The second housing 20 of the embodiment of the present application includes four elastic buckles 60, such as Figure 3 As shown, one of the four first bottom walls 201 (i.e. Figure 3 A resilient buckle 60 is provided on the side indicated by the X1 direction. Figure 4 As shown, another first bottom wall 201 (i.e. Figure 4 Two elastic buckles 60 are provided on the side indicated by the X2 direction. Figure 3 and Figure 4 As shown, the third first bottom wall 201 (i.e. Figure 3 and Figure 4 An elastic buckle 60 is provided on one side (in the direction Y2).

[0072] Continue to refer Figure 3 and Figure 4 It can be seen that the above-mentioned four elastic buckles 60 are used to elastically abut against the outer wall of the first shell 10 to limit the movement of the first shell 10 and the second shell 20 along the first direction.

[0073] By adopting the above technical solution, the four elastic buckles 60 provided on the second shell 20 can abut against the corresponding limiting protrusions 70 provided on the first shell 10, so that the first shell 10 and the second shell 20 can be elastically connected with better connection stability.

[0074] The embodiment of the present application does not impose any specific restrictions on the arrangement of the elastic clip 60. As long as one or more elastic clips 60 are arranged on at least two of the four first bottom walls 201, the arrangement method for realizing the connection between the first shell 10 and the second shell 20 falls within the protection scope of the embodiment of the present application.

[0075] Continue to refer Figure 3 and Figure 4 In a possible implementation, the first shell 10 includes a first outer wall 102 , a second outer wall 103 , a third outer wall 104 and a fourth outer wall 105 , and the first outer wall 102 , the second outer wall 103 , the third outer wall 104 and the fourth outer wall 105 define the side periphery of the first shell 10 .

[0076] Along the second direction (such as Figure 3 and Figure 4The first outer wall 102 and the second outer wall 103 are arranged opposite to each other, the first outer wall 102 is provided with a limiting protrusion 70, and the second outer wall 103 is provided with two limiting protrusions 70; along the third direction (such as Figure 3 and Figure 4 The third outer wall 104 and the fourth outer wall 105 are arranged opposite to each other, and a limiting protrusion 70 is provided on the third outer wall 104.

[0077] The limiting protrusions 70 correspond one-to-one with the elastic buckles 60, and it can be seen that the four elastic buckles 60 abut against four limiting protrusions 70. Accordingly, the embodiment of the present application does not specifically limit the arrangement of the limiting protrusions 70, and as long as they correspond one-to-one with the elastic buckles 60, they all belong to the protection scope of the embodiment of the present application.
