[0040] Please also refer to Figure 1 、 Figure 2 、 Figure 5 and Figure 7 , the RF antenna 100 provided in an embodiment of the present application is now described.

[0041] The radio frequency antenna 100 provided in this application includes a circuit board 20 and a rod sleeve 10 .

[0042] The circuit board 20 has a first surface 21 and a second surface 22 that are parallel and spaced apart along a first direction.

[0043] As shown in the figure, the first direction is the x direction shown in the figure, the first direction x is the thickness direction of the circuit board 20, the first surface 21 and the second surface 22 are both perpendicular to the first direction x, and the first surface 21 and the second surface 22 are arranged at intervals along the first direction x so that the circuit board 20 is perpendicular to the first direction x.

[0044] The circuit board 20 is a printed circuit board. A printed circuit is printed on at least one of the first surface 21 and the second surface 22 of the circuit board 20. The printed circuit includes a feeding structure and a radiator. The electrical signal is transmitted to the radiator through the feeding structure to stimulate the radiator to oscillate and generate electromagnetic waves.

[0045] An inner cavity 13 is provided in the rod sleeve 10, and at least part of the circuit board 20 is located in the inner cavity 13. A first positioning block 11 and a second positioning block 12 are provided in the inner cavity 13. The first positioning block 11 abuts against the first surface 21, and the second positioning block 12 abuts against the second surface 22, and the first positioning block 11 and the second positioning block 12 are arranged along a second direction orthogonal to the first direction x.

[0046] like Figure 7 As shown, the rod sleeve 10 is a thin-walled hollow structure, and a hollow inner cavity 13 is provided inside the rod sleeve 10. A first positioning block 11 and a second positioning block 12 are provided on the inner wall of the rod sleeve 10. The first positioning block 11 and the second positioning block 12 are fixedly connected to the rod sleeve 10, and the first positioning block 11 and the second positioning block 12 are arranged at intervals along the first direction x, that is, the first positioning block 11 is provided on the side of the circuit board 20 facing the first surface 21 along the first direction x, and the second positioning block 12 is located on the side of the circuit board 20 facing the second surface 22 along the first direction x.

[0047] The second direction is the y direction shown in the figure, and the first positioning block 11 and the second positioning block 12 are respectively abutted against the first surface 21 and the second surface 22 of the circuit board 20, and the first positioning block 11 and the second positioning block 12 are spaced apart in the second direction y to limit the freedom of rotation of the circuit board 20 around the second direction y when the circuit board 20 is abutted and fixed by the first positioning block 11 and the second positioning block 12 to fix the circuit board 20.

[0048] In other embodiments (not shown in the figures), the second direction is the z direction shown in the figures, and the first positioning block 11 and the second positioning block 12 are arranged at intervals along the z direction in the figures to limit the freedom of rotation of the circuit board 20 around the z direction in the figures when the circuit board 20 is abutted and fixed by the first positioning block 11 and the second positioning block 12 to fix the circuit board 20.

[0049] The beneficial effect of the RF antenna 100 provided in the present application is that the circuit board 20 of the RF antenna 100 provided in the present application is fixed in the inner cavity 13 of the rod sleeve 10 by clamping the first positioning block 11 and the second positioning block 12. Compared with the related art of fixing the circuit board 20 in the inner cavity 13 of the rod sleeve 10 by gluing fixing parts such as foam, the RF antenna 100 provided in the present application has a smaller tolerance and stable processing quality, which improves the yield rate of the RF antenna 100 during processing, and the circuit board 20 is fixed in the inner cavity 13 of the rod sleeve 10 with good stability and is not prone to shaking and producing abnormal noise, thereby improving the user experience, so that the RF antenna 100 provided in the present application has the advantages of low scrap rate and good user experience.

[0050] In addition, the circuit board 20 is clamped by the first positioning block 11 and the second positioning block 12 to fix the circuit board 20 in the rod sleeve 10. Compared with the related art that uses fixing parts such as glued foam to fix the circuit board 20 in the inner cavity 13 of the rod sleeve 10, the material cost of foam and adhesive is reduced, thereby reducing the production cost of the RF antenna 100 provided in this application.

[0051] In other embodiments, the first positioning block 11 and the second positioning block 12 are integrally formed with the rod sleeve 10 .

[0052] In some embodiments provided in this application, an opening 14 is provided at the end of the rod sleeve 10 to connect the inner cavity 13 and the outside of the rod sleeve 10 through the opening 14;

[0053] The first positioning block 11 includes a first abutting portion 111 and a first guiding portion 112. The first abutting portion 111 abuts against the circuit board 20. The first guiding portion 112 is provided on a side of the first abutting portion 111 facing the opening 14. The distance between the first guiding portion 112 and the circuit board 20 gradually decreases in a direction away from the opening 14.

[0054] The second positioning block 12 includes a second abutting portion 121 and a second guiding portion 122 . The second abutting portion 121 abuts against the circuit board 20 . The second guiding portion 122 is provided on a side of the second abutting portion 121 facing the opening 14 , and a distance between the second guiding portion 122 and the circuit board 20 gradually decreases in a direction away from the opening 14 .

[0055] like Figure 8 As shown in the figure, the z direction is the third direction, and the rod sleeve 10 extends along the third direction z, so that the size of the rod sleeve 10 in the third direction z is much larger than the size of the rod sleeve 10 in the first direction x and the size of the rod sleeve 10 in the second direction y. The opening 14 is provided at one end of the rod sleeve 10 along the third direction z, and the opening 14 passes through the inner wall of the rod sleeve 10 and the outer wall of the rod sleeve 10, that is, one end of the opening 14 is connected to the inner cavity 13, and the other end of the opening 14 is connected to the outer wall of the rod sleeve 10.

[0056] The first positioning block 11 extends along the third direction z, and the portion of the first positioning block 11 away from the opening 14 in the third direction z forms a first abutting portion 111, and the first abutting portion 111 is suitable for abutting against the first surface 21 of the circuit board 20. The portion of the first positioning block 11 close to the opening 14 in the third direction z forms a first guiding portion 112, and the first guiding portion 112 is provided with a first slope 1121 on the side facing the circuit board 20, and an angle is formed between the first slope 1121 and the third direction z, so that the distance between any point on the first slope 1121 and the circuit board 20 gradually decreases to 0 in the direction away from the opening 14 in the third direction z.

[0057] The second positioning block 12 extends along the third direction z, and the part of the second positioning block 12 away from the opening 14 in the third direction z forms a second abutment portion 121, and the second abutment portion 121 is suitable for abutting against the second surface 22 of the circuit board 20. The part of the second positioning block 12 close to the opening 14 in the third direction z forms a second guide portion 122, and the second guide portion 122 is provided with a second slope 1221 on the side facing the circuit board 20, and an angle is formed between the second slope 1221 and the third direction z, so that the distance between any point on the second slope 1221 and the circuit board 20 gradually decreases to 0 in the direction away from the opening 14 in the third direction z.

[0058] The size of the first positioning block 11 in the first direction x gradually increases along the direction away from the opening 14 until it abuts the first surface 21, and the size of the second positioning block 12 in the first direction x gradually increases along the direction away from the opening 14 until it abuts the second surface 22. When the circuit board 20 enters the inner cavity 13 from the opening 14, the first guide portion 112 and the second guide portion 122 can guide the end of the circuit board 20 to pass through the gap between the first positioning block 11 and the second positioning block 12.

[0059] Therefore, during the assembly process of the RF antenna 100 provided in the present application, the circuit board 20 and the rod sleeve 10 are progressively interference fit to reduce the assembly difficulties caused by changes in the process tolerance of the circuit board 20 in the first direction x or the second direction y, thereby reducing the risk of breakage of the circuit board 20 during the assembly process, so that the RF antenna 100 provided in the present application has the advantage of a low scrap rate.

[0060] In some embodiments provided in the present application, the first positioning block 11 and the second positioning block 12 are both provided at the end of the inner cavity 13 away from the opening 14 .

[0061] like Figure 5 and Figure 7As shown, the first positioning block 11 and the second positioning block 12 are both located at the end of the inner cavity 13 away from the opening 14 in the third direction z, and the first positioning block 11 and the second positioning block 12 are positioned at the same position in the third direction z. As a result, the first positioning block 11 and the second positioning block 12 are both clamped to the end of the circuit board 20 along the third direction z, on the one hand supporting the end of the circuit board 20 along the third direction z, and on the other hand allowing the first positioning block 11 and the second positioning block 12 to avoid the printed circuit on the circuit board 20.

[0062] In other embodiments (not shown), the first positioning block 11 and the second positioning block 12 are located in the middle section of the inner cavity 13 in the third direction z, and the first positioning block 11 and the second positioning block 12 abut against locations on the circuit board 20 where no printed circuit is printed. Thus, by reducing the distance between the first positioning block 11 and the opening 14, that is, the distance between the second positioning block 12 and the opening 14, the overhang length of the circuit board 20 when fixed in the rod sleeve 10 is reduced, thereby increasing the rigidity of the circuit board 20 and reducing the probability of the circuit board 20 loosening and generating abnormal noise, thereby improving the user experience.

[0063] In other embodiments (not shown), there are multiple first positioning blocks 11, each comprising a plurality of first positioning groups. There are multiple second positioning blocks 12, each comprising a plurality of second positioning groups. The plurality of first positioning groups and the plurality of second positioning groups are arranged along the third direction z, with the first positioning groups corresponding to the second positioning groups. The first positioning groups and the corresponding second positioning groups are arranged along the first direction x and are respectively sandwiched between the first surface 21 and the second surface 22. Thus, the plurality of first positioning groups and the plurality of second positioning groups arranged along the third direction z improve the support effect on the circuit board 20.

[0064] In some embodiments provided in the present application, there are multiple first positioning blocks 11, and the multiple first positioning blocks 11 are arranged at intervals along the second direction y, the second direction y is orthogonal to the first direction x, and the second positioning block 12 is located between two adjacent first positioning blocks 11 in the second direction y.

[0065] like Figure 7 As shown, there are two first positioning blocks 11, which are arranged at intervals along the second direction y and symmetrically arranged about the first direction x. There is one second positioning block 12, which is located on the symmetry axis of the two first positioning blocks 11.

[0066] Therefore, the first positioning block 11 and the second positioning block 12 are arranged at intervals so that the force exerted by the first positioning block 11 on the circuit board 20 and the force exerted by the second positioning block 12 on the circuit board 20 remain balanced, thereby avoiding deformation of the circuit board 20 due to uneven force in the first direction x and the second direction y, thereby reducing the failure rate of the circuit board 20 and improving user experience.

[0067] In some embodiments provided in the present application, the RF antenna 100 further includes a positioning plug 30, at least a portion of the positioning plug 30 is assembled on the inner side of the opening 14, one end of the circuit board 20 abuts against the end of the inner cavity 13 away from the opening 14, and a card slot 31 is provided on the side of the positioning plug 30 facing the inner cavity 13, and the other end of the circuit board 20 fits into the card slot 31 and abuts against the card slot 31.

[0068] like Figure 3 and Figure 4 As shown, the positioning plug 30 is interference fitted into the inner side of the opening 14, and a slot 31 is provided at one end of the positioning plug 30 facing the inner cavity 13. The width of the slot 31 extends along the first direction x, the depth of the slot 31 extends along the third direction z, and the length of the slot 31 extends along the second direction y. The notch of the slot 31 faces one end of the inner cavity 13 in the third direction z, and the nominal dimension of the width dimension of the slot 31 is the same as the nominal dimension of the circuit board 20 in the first direction x, so that the circuit board 20 is interference fit into the slot 31 at one end facing the positioning plug 30.

[0069] Thus, one end of the circuit board 20 along the third direction z is supported by the first positioning block 11 and the second positioning block 12 , and the other end of the circuit board 20 along the third direction z is supported by the positioning plug 30 .

[0070] In some embodiments provided in the present application, the length of the slot 31 gradually increases in a direction approaching the inner cavity 13 .

[0071] like Figure 4 As shown, the length dimension of the card slot 31 is the dimension of the card slot 31 in the second direction y, the length dimension of the card slot 31 gradually increases in the third direction z, and the length dimension at the slot opening of the card slot 31 is greater than the length dimension at the bottom of the card slot 31.

[0072] Therefore, when the end of the circuit board 20 abuts against the slot 31, the two ends of the circuit board 20 along the second direction y respectively abut against the first wall 311 and the second wall 312 in the length direction of the slot 31. On the one hand, the end of the circuit board 20 can be positioned in the second direction y through the slot 31, so that the circuit board 20 is fitted into the slot 31 symmetrically along the first direction x, thereby extending the circuit board 20 along the axis of the rod sleeve 10, avoiding the risk of failure caused by the circuit board 20 colliding with the inner wall of the rod sleeve 10.

[0073] In some embodiments provided in the present application, the slot 31 has a first wall 311 and a second wall 312 arranged opposite to each other in its length direction. The first wall 311 and the second wall 312 are arranged at an angle to each other so that the length dimension of the slot 31 gradually increases in the direction approaching the inner cavity 13.

[0074] like Figure 4 As shown, the first wall 311 and the second wall 312 are symmetrically arranged with respect to the first direction x, and both the first wall 311 and the second wall 312 have an angle with the second direction y.

[0075] Compared with the related art, the RF antenna 100 provided in the present application increases the depth dimension of the card slot 31 in the third direction z and reduces the length dimension of the card slot 31 in the second direction y, so that the shape of the card slot 31 of the RF antenna 100 provided in the present application is narrower and longer, and the distance between the contact point between the circuit board 20 and the positioning plug 30 and the end face of the positioning plug 30 along the third direction z, that is, the installation margin of the circuit board 20, is increased.

[0076] Therefore, on the one hand, the installation difficulty of the RF antenna 100 provided in the present application is reduced, and on the other hand, it can prevent the circuit board 20 from loosening and tilting in the card slot 31, thereby reducing the installation defect rate of the RF antenna 100 provided in the present application.

[0077] In other embodiments, Figure 9 As shown, a first elastic layer 313 is provided on the surface of the first wall 311 , and a second elastic layer 314 is provided on the surface of the second wall 312 .

[0078] like Figure 9 As shown, the first elastic layer 313 is coated on the first wall 311 and the second elastic layer 314 is coated on the second wall 312. The materials of the first elastic layer 313 and the second elastic layer 314 are elastic materials such as rubber. The thickness of the first elastic layer 313 and the thickness of the second elastic layer 314 are uniform and the same.

[0079] Therefore, by setting a first elastic layer 313 on the first wall 311 and a second elastic layer 314 on the second wall 312, when the end of the circuit board 20 is assembled into the slot 31, the two ends of the circuit board 20 along the second direction y respectively abut against the first elastic layer 313 and the second elastic layer 314. On the one hand, it can reduce the wear between the circuit board 20 and the positioning plug 30, thereby avoiding the RF antenna 100 provided in the present application from loosening due to the gap between the circuit board 20 and the positioning plug 30 during long-term use. On the other hand, the first elastic layer 313 and the second elastic layer 314 can both produce slight deformations, so that the slot 31 can be compatible with the tolerance changes of the circuit board 20 caused by the process.

[0080] In some other embodiments provided herein, the first wall 311 is provided with a first chamfered surface 3111 at one end of the slot 31, and the first elastic layer 313 is provided with a third chamfered surface 3131 at one end of the slot 31. The first chamfered surface 3111 and the third chamfered surface 3131 are arranged coplanarly.

[0081] The second wall 312 has a second chamfered surface 3121 at one end of the slot 31 , and the second elastic layer 314 has a fourth chamfered surface 3141 at one end of the slot 31 . The second chamfered surface 3121 and the fourth chamfered surface 3141 are arranged to overlap.

[0082] like Figure 9 As shown, the first chamfered surface 3111 is provided at one end of the notch extending from the first wall 311 to the card slot 31, the third chamfered surface 3131 is provided at one end of the notch extending from the first elastic layer 313 to the card slot 31, the second chamfered surface 3121 is provided at one end of the notch extending from the second wall 312 to the card slot 31, and the fourth chamfered surface 3141 is provided at one end of the notch extending from the second elastic layer 314 to the card slot 31. The first chamfered surface 3111 and the third chamfered surface 3131 are coplanar, the second chamfered surface 3121 and the fourth chamfered surface 3141 are coplanar, and the first chamfered surface 3111 and the third chamfered surface 3131 are symmetrically arranged about the first direction x.

[0083] Therefore, by setting the first chamfered surface 3111, the third chamfered surface 3131, the second chamfered surface 3121 and the fourth chamfered surface 3141, chamfers are set at the notch of the slot 31. On the one hand, it is convenient to guide the end of the circuit board 20 to fit into the slot 31, and on the other hand, it reduces the collision between the end of the circuit board 20 and the partial positioning plug 30 at the notch of the slot 31 when the circuit board 20 is assembled.

[0084] In some embodiments provided in the present application, the positioning plug 30 is provided with a positioning groove 33 and a wire groove 32. The positioning groove 33 and the wire groove 32 both pass through the positioning plug 30 along the extension direction of the opening 14. The rod sleeve 10 is provided with a positioning boss 15. The positioning boss 15 can be assembled into the positioning groove 33. There is a gap between the bottom of the positioning groove 33 and the positioning boss 15.

[0085] like Figure 5 and Figure 6 As shown, the positioning groove 33 and the wire groove 32 both penetrate the positioning plug 30 along the third direction z. The inner wall of the rod sleeve 10 is provided with a positioning boss 15 extending along the third direction z. The positioning boss 15 can be fitted into the positioning groove 33 to limit the circumferential position of the positioning plug 30 in the third direction z when the positioning plug 30 is installed at the opening 14.

[0086] During the automated assembly of the antenna in the related art, the wire 200 is easily misassembled into the positioning groove 33 , and the wire 200 is easily broken when the positioning boss 15 is engaged with the positioning groove 33 , thereby causing defects.

[0087] Therefore, there is a gap between the positioning boss 15 of the RF antenna 100 provided in the present application and the bottom of the positioning groove 33, so that the wire 200 can be avoided when it is mistakenly assembled into the positioning groove 33, thereby reducing the scrap rate of the RF antenna 100 provided in the present application.

[0088] In some embodiments provided in the present application, the wire trough 32 includes a guide trough section 321, which is arranged between the bottom of the wire trough 32 and the slot of the wire trough 32, and the width of the guide trough section 321 first decreases and then increases in the direction toward the slot of the wire trough 32.

[0089] like Figure 6 As shown, the wire groove 32 is used for allowing the wire 200 to pass through the positioning plug 30 and extend into the inner cavity 13 and be connected to the circuit board 20. The notch of the wire groove 32 is connected to the outer side of the positioning plug 30 along the first direction x. A guide groove section 321 is provided in the guide groove. The guide groove section 321 is a part of the wire groove 32 close to its notch. The width dimension of the guide groove section 321 is the dimension of the guide groove section 321 in the second direction y. The width dimension of the guide groove section 321 in the second direction y gradually decreases and then gradually increases along the direction from the notch of the wire groove 32 to the bottom of the wire groove 32, and the minimum value of the width dimension of the guide groove section 321 in the second direction y is less than or equal to the diameter dimension of the wire 200.

[0090] Thus, on the one hand, the guide groove section 321 guides the wire 200 into the wire groove 32 , and on the other hand, the width of the guide groove section 321 in the second direction y transitions smoothly to reduce the probability of the wire 200 being damaged in the wire groove 32 .

[0091] The communication device provided by this application is described below.

[0092] The communication device provided in this application includes the radio frequency antenna 100 in any one of the above embodiments.

[0093] The communication device provided in the present application includes a feeding network and at least one RF antenna 100 provided in the present application. The feeding network includes a wire 200. The wire 200 passes through the positioning plug 30 of the RF antenna 100 and extends into the inner cavity 13 of the rod sleeve 10 and is connected to the circuit board 20 to transmit or receive electromagnetic signals through the RF antenna 100.

[0094] Therefore, the RF antenna 100 provided in the present application has the advantage of a low scrap rate, which reduces the production cost and failure rate of the RF antenna 100, thereby making the communication device provided in the present application have the advantages of a low failure rate and low production cost.

[0095] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present application should be included in the scope of protection of the present application.
