Description

TECHNICAL FIELD

[0001] The present disclosure relates to the technical field of antennas, and in particular to a PCB dipole support structure and an antenna. BACKGROUND

[0002] A dipole is a core component of an antenna, which has the function of guiding and amplifying electromagnetic waves, so that the electromagnetic signal received by the antenna is stronger.

DETAILED DESCRIPTION

[0046] In order to enable a more clear understanding of the above-mentioned objects, features and advantages of the present disclosure, the schemes of the present disclosure will be further described below. It should be noted that the embodiments of the present disclosure and the features in the embodiments can be combined with each other without conflict.

[0047] In the following description, a lot of specific details are set forth in order to give a thorough understanding of the present disclosure, but the present disclosure can also be implemented in other manners different from those described herein; obviously, the embodiments described in the specification are only a part of the embodiments of the present disclosure, and not all the embodiments.

[0048] The PCB vibrator is a kind of vibrator that realizes electromagnetic field propagation by printing circuit on synthetic resin. When the structure size of the PCB vibrator is large, if the PCB vibrator is directly installed on the reflector plate, the shaking amplitude of the PCB vibrator is large and the PCB vibrator is easy to bend when vibration occurs, such as during reliability test, which leads to the situation that the vibrator welding point is pulled and torn, affecting the electrical performance of the PCB vibrator.

[0049] Based on this, the present disclosure provides a PCB vibrator support structure and an antenna with the same, and effective support and fixation of the PCB vibrator are realized through the PCB vibrator support structure, so as to improve the stability of the PCB vibrator. The PCB vibrator support structure and the antenna will be described in detail through specific embodiments as follows:

[0050] Embodiment one

[0051] Reference Figures 1 to 6As shown, the embodiment provides a PCB vibrator support structure, comprising a base 1 and a ring-shaped support frame 2 arranged on the base 1.

[0052] Wherein, the side of the ring-shaped support frame 2 away from the base 1 is provided with at least one first clamping structure 21 for fixing the vibrator arm 31 of the PCB vibrator. The bottom of the base 1 is provided with a fixing structure 13 for fixing the PCB vibrator support structure on the reflecting plate 4. The base 1 has a cavity 110, and the balun connected with the vibrator arm 31 can pass through the cavity 110 to be connected with the wiring board 32 located on the reflecting plate 4.

[0053] That is, the entire PCB vibrator support structure is fixed on the reflecting plate 4 through the fixing structure 13 at the bottom of the base 1, the vibrator arm 31 is supported by the ring-shaped support frame 2, and the vibrator arm 31 is clamped and fixed by the first clamping structure 21 on the ring-shaped support frame 2, that is, by arranging the PCB vibrator support structure on the reflecting plate 4, the effective support and fixation of the PCB vibrator are realized through the PCB vibrator support structure, so that when vibration occurs, the shaking amplitude of the PCB vibrator can be effectively reduced to a certain extent, the situation that the vibrator solder joint is pulled is avoided to a certain extent, the PCB vibrator is effectively protected, and the performance of the PCB vibrator is more stable. At the same time, the vibrator arm is clamped on the ring-shaped support frame 2 through the first clamping structure 21, so that the assembly of the PCB vibrator on the support structure is more rapid and convenient.

[0054] In the embodiment, the PCB vibrator specifically includes two groups of polarized orthogonal vibrator arms 31. More preferably, the first clamping structure 21 can be provided as at least two, and the at least two first clamping structures 21 are arranged along the circumference of the ring-shaped support frame 2. Referring to Figure 1 As shown, four first clamping structures 21 are arranged on the ring-shaped support frame 2, and one group of vibrator arms 31 corresponds to two first clamping structures 21, thereby further improving the fixing effect of the vibrator arm 31 and improving the stability of the PCB vibrator.

[0055] Of course, in other implementations, the PCB vibrator can also include one group of vibrator arms 31.

[0056] In the embodiment, the ring-shaped support frame 2 is specifically a circular ring-shaped support frame. Of course, in other implementations, the ring-shaped support frame 2 can also be a square ring. The vibrator arm 31 is supported by the ring-shaped support frame 2, so that the support effect of the vibrator arm 31 is better, and the entire support structure is more stable.

[0057] In a specific implementation, the base 1 may include a base body 11 and at least two supporting ribs 12. The base body 11 may be a hollow columnar structure, with its inner cavity forming the aforementioned cavity 110. The fixing structure 13 is specifically disposed at the bottom of the base body 11. At least two supporting ribs 12 are arranged circumferentially along the base body 11 and connected between the base body 11 and the annular support frame 2. In the direction from the base body 11 to the annular support frame 2, the supporting ribs 12 are inclined away from the axis of the annular support frame 2. That is, one end of the supporting rib 12 is connected to the base body 11, and the other end of the supporting rib 12 is connected to the annular support frame 2. The outer contour dimension of the annular support frame 2 is larger than the outer contour dimension of the base body 11, thereby enabling the support structure to better support the larger PCB oscillator.

[0058] In this embodiment, there are four support ribs 12, which are arranged at equal intervals along the circumference of the base 11. In practice, the base 11, the support ribs 12, and the annular support frame 2 can all be made of plastic. The support ribs 12, the base 11, and the annular support frame 2 can be integrally formed.

[0059] Continue to refer to Figure 1 , Figure 2 as well as Figure 5 As shown, the first engaging structure 21 specifically includes two first latches 211 disposed opposite to each other on the annular support frame 2. The first latches 211 extend in a direction away from the annular support frame 2, and the two first latches 211 are respectively engaged on both sides of the vibrator arm 31. During installation, the vibrator arm 31 is directly pressed downward into the space between the two first latches 211, and the two first latches 211 engage with the vibrator arm 31 from both sides. The first latches 211 can be integrally formed with the annular support frame 2.

[0060] Specifically, the end of the first latch 211 furthest from the annular support frame 2 has an engaging surface 212, which together with the annular support frame 2 forms a limiting space for vertically limiting the vibrator arm 31. It can be understood that the vibrator arm 31 is restricted between the engaging surface 212 and the annular support frame 2.

[0061] Since the two first buckles 211 are respectively attached to both sides of the vibrator arm 31, it is not necessary to open buckle holes on the vibrator arm 31 to achieve the engagement of the vibrator arm 31 with the two first buckles 211, and there is no need to change the structure of the vibrator arm 31.

[0062] Reference Figure 1As shown, the first clamping structure 21 further comprises a vibrator arm positioning column 213 for cooperating with a positioning hole of the vibrator arm 31. When the first clamping buckle 211 is clamped on the vibrator arm 31, the vibrator arm positioning column 213 is arranged in the positioning hole of the vibrator arm 31. Through the cooperation of the vibrator arm positioning column 213 and the vibrator arm positioning hole, the left and right movement of the vibrator arm 31 is limited to a certain extent, and the vibrator arm positioning column 213 can also play a good guiding role when the vibrator arm 31 is installed. The vibrator arm positioning column 213 is specifically located between the two first clamping buckles 211, thereby further improving the fixing effect of the first clamping structure 21 on the vibrator arm 31.

[0063] The first clamping structure 21 can further comprise a vibrator arm limiting rib 214 arranged on the annular support frame 2. The vibrator arm limiting rib 214 is located between the two first clamping buckles 211. The vibrator arm 31 has a first face 311 and a second face opposite to each other. As shown in the figure, Figure 5 As shown, the top face of the vibrator arm 31 is the first face 311, and the bottom face of the vibrator arm 31 is the second face. When the vibrator arm 31 cooperates with the first clamping buckle 211, the clamping face 212 abuts against the first face 311 of the vibrator arm 31, and the vibrator arm limiting rib 214 abuts against the second face of the vibrator arm 31, thereby further improving the limiting effect of the vibrator arm 31 in the vertical direction. Moreover, the vibrator arm limiting rib 214 can improve the structural strength of the annular support frame 2 to a certain extent, thereby improving the strength of the entire support structure. As shown in the figure, Figure 1 As shown, in the embodiment, four first clamping structures 21 are arranged on the annular support frame 2, and the vibrator arm limiting rib 214 is arranged on two of the first clamping structures 21.

[0064] As shown in the figure, Figures 3 to 6 As shown, in the embodiment, the fixing structure 13 specifically comprises a limiting arm 131 arranged on the bottom of the base 1. The limiting arm 131 is at least two, and the at least two limiting arms are arranged in a circumferential direction of the base 1 and have the same extension direction. Correspondingly, the positions of the limiting holes 41 of the reflecting plate 4 corresponding to the limiting arms have a limiting hole 41 through which the limiting arm can extend to the bottom of the reflecting plate 4.

[0065] Specifically, when installing, the base 1 is installed on the reflecting plate 4 by a side pushing manner, so that each limiting arm passes through the corresponding limiting hole 41 and extends to the bottom of the reflecting plate 4. Specifically, the limiting arm 131 can be attached to the bottom face of the reflecting plate 4.

[0066] Among all the limiting arms, at least one limiting arm is provided with a first mounting hole 134, and the reflecting plate 4 is provided with a second mounting hole 42, and the base 1 is fixed on the reflecting plate 4 through the fastener 44 penetrating the first mounting hole 134 and the second mounting hole 42. That is, when each limiting arm is penetrated out of the corresponding limiting through hole 41 and is moved to the position, at this time, the first mounting hole 134 is just aligned with the second mounting hole 42, and then the fastener 44 is penetrated into the first mounting hole 134 and the second mounting hole 42, and the limiting arm is locked with the reflecting plate 4 through the fastener 44, that is, the supporting structure is locked with the reflecting plate 4.

[0067] Referring to Figure 5 and Figure 6 In the embodiment, the fastener 44 is specifically a rivet, and the first limiting arm 132 is locked with the reflecting plate 4 through the rivet. Of course, in other implementation manners, the fastener 44 can also be a screw or other structures.

[0068] Referring to Figures 3 to 6 At least two limiting arms include the first limiting arm 132 and the second limiting arm 133, wherein the length of the first limiting arm 132 is greater than the length of the second limiting arm 133, and the first mounting hole 134 is provided on the first limiting arm 132. By providing the first mounting hole 134 on the first limiting arm 132 with a longer length, the manufacturing and assembly are more convenient.

[0069] Further, the fixing structure 13 further includes an elastic arm 135 provided at the bottom of the base 1, the elastic arm 135 extends towards the direction away from the side wall of the base 1, and the elastic arm 135 is pressed on the top of the reflecting plate 4 when the limiting arm 131 cooperates with the reflecting plate 4. In this way, after the supporting structure supporting the PCB vibrator is installed on the reflecting plate 4, the elastic arm 135 has a certain elastic force with the reflecting plate 4, which ensures that the base 1 can be tightly attached to the reflecting plate 4, and further improves the stability of the PCB vibrator on the supporting structure. Wherein, the elastic arm 135 can be integrally formed with the base 1. Further, the elastic arm 135 and the base 1 are further provided with a reinforcing rib 137 to enhance the structural strength of the elastic arm 135.

[0070] Wherein, the side of the elastic arm 135 facing the reflecting plate 4 is provided with a first limiting protrusion 136, and the reflecting plate 4 is provided with a first limiting hole 43 cooperating with the first limiting protrusion 136. When the base 1 and the reflecting plate 4 are cooperated in place through the limiting arm 131 and the limiting through hole 41, the first limiting protrusion 136 is just inserted into the first limiting hole 43, and the two cooperate to further limit the horizontal movement of the base 1.

[0071] In the implementation, at least two elastic arms 135 can be arranged to improve the cooperation effect of the base 1 and the reflecting plate 4, and further improve the stability of the support structure. In the embodiment, the elastic arms 135 are two, and the two elastic arms 135 are arranged on the two sides of the base 1. The second limiting arm 133 can be arranged at the bottom of the elastic arm 135 for the convenience of manufacturing.

[0072] The wiring board 32 of the PCB vibrator is arranged on the reflecting plate 4, and the wiring board 32 is used to supply power for the vibrator. The wiring board 32 can be fixed on the reflecting plate 4 by rivets. The balun connected with the vibrator arm 31 penetrates the cavity 110 to be connected with the wiring board 32. Specifically, the balun is connected with the wiring board 32 by welding.

[0073] The bottom of the base 1 is further provided with a wiring board limiting structure for limiting the wiring board 32. The wiring board limiting structure specifically includes a wiring board limiting surface 141. When the base 1 cooperates with the reflecting plate 4, the wiring board limiting surface 141 is pressed on the wiring board 32.

[0074] Referring to Figures 3 to 5 In the embodiment, the wiring board limiting surface 141 is three, and the three wiring board limiting surfaces 141 are arranged along the circumference of the base 1. The bottom of the base 1 is provided with a wiring board limiting arm 142, and the bottom surface of the wiring board limiting arm 142 is specifically formed as one of the wiring board limiting surfaces 141.

[0075] More preferably, a second limiting protrusion 143 can be arranged on the side of the wiring board limiting surface 141 facing the wiring board 32, and the wiring board 32 has a second limiting hole 321 matched with the second limiting protrusion 143.

[0076] When the balun of the PCB vibrator is welded with the wiring board 32, the plane of the wiring board 32 is tightly attached to the wiring board limiting surface 141, and at the same time, the second limiting hole 321 on the wiring board 32 is matched with the second limiting protrusion 143 on the wiring board limiting surface 141, which fixes the wiring board 32, so that the wiring board 32 and the balun do not move during welding, and the welding is convenient, which is equivalent to a welding tool with foolproof and uniqueness.

[0077] Referring to Figure 2 The cavity wall of the cavity 110 of the base 1 is provided with a balun limiting structure for limiting the balun. Specifically, the balun limiting structure includes a balun limiting hole 111 and a balun limiting groove 112, which limits the balun to make the installation of the balun more smooth, and protects the balun from vibration after installation, thereby further improving the stability of the PCB vibrator.

[0078] In order to improve the radiation performance of the PCB vibrator, a director plate 5 is usually added above the PCB vibrator. In the embodiment, at least two second clamping structures 22 for fixing the director plate 5 are further arranged on the annular support frame 2, and the at least two second clamping structures 22 are arranged at intervals along the circumference of the annular support frame 2, so as to facilitate the installation of the director plate 5.

[0079] That is, the director plate 5 is clamped on the annular support frame 2 through the second clamping structure 22, so that the installation of the director plate 5 is more convenient and fast, the assembly efficiency is improved, and no additional director plate support frame is needed. That is, the PCB vibrator support structure can realize the fixation of the PCB vibrator and the fixation of the director plate 5 at the same time, so that the function of the support structure is diversified.

[0080] Continuing to refer to Figure 1 , Figure 2 and Figure 5 , the second clamping structure 22 specifically comprises a second buckle 221 extending away from the annular support frame 2, and the second buckle 221 is used for matching and clamping with the clamping hole 51 on the director plate 5, so as to fix the director plate 5 on the annular support frame 2. Specifically, when the director plate 5 is directly pressed down, the clamping hole 51 on the director plate 5 matches and clamps with the second buckle 221, so that the assembly of the director plate 5 is realized, and the installation is reliable and convenient.

[0081] Further, the second clamping structure 22 further comprises a protruding rib 222 arranged on the annular support frame 2 and protruding towards the director plate 5. Specifically, when the director plate 5 matches and clamps with the second buckle 221, the protruding rib 222 abuts against one side of the director plate 5 facing the annular support frame 2. That is, the second buckle 221 and the protruding rib 222 vertically limit the director plate 5. That is, the director plate 5 is effectively supported by the protruding rib 222, so that a certain distance is maintained between the director plate 5 and the vibrator arm 31, so as to improve the stability and radiation performance of the vibrator.

[0082] The protruding rib 222 can be connected with the second buckle 221, so that the protruding rib 222 also plays a role of a reinforcing rib, so as to improve the structural strength and stability of the second buckle 221, and further improve the strength of the entire second clamping structure 22. Specifically, the protruding rib 222 can be arranged on one side of the second buckle 221 close to the center of the annular support frame 2, so that the support effect on the director plate is improved, and interference of the protruding rib 222 with other components on the support structure is avoided.

[0083] The second clamping structure 22 further comprises a limiting column 223, and the director plate 5 has a director plate limiting hole 52 for cooperating with the limiting column 223. The limiting column 223 cooperates with the director plate limiting hole 52 to limit the horizontal movement of the director plate 5 to a certain extent.

[0084] The convex rib 222 is specifically arranged between the limiting column 223 and the second buckle 221, and is connected with the limiting column 223 and the second buckle 221 respectively, so that the convex rib 222 can simultaneously play a role of strengthening the limiting column 223 and the second buckle 221, thereby improving the structural strength of the entire second clamping structure 22. Specifically, the limiting column 223 is arranged on one side of the second buckle 221 close to the center of the annular support frame 2, so as to avoid interference of the limiting column 223 with other components on the support structure.

[0085] In the embodiment, four second clamping structures 22 are specifically arranged on the annular support frame 2 to clamp the guide vane 5 from the entire circumferential direction of the guide vane 5, thereby further improving the stability of the guide vane 5.
