Definitions

  • This invention relates to a wireless transceiver having a rotary antenna and, particularly, to a wireless transceiver having a double rotary antenna.
  • Wireless transceivers are in growing use, many of them having a rotary or swivel antenna so that the antenna can be directed in the most favorable direction for transmission and receipt of signals.
  • An example of the swivel antenna is found in Taiwan Pat. No. M317082 , wherein the antenna is carried by a connection member which is attached to an electronic device.
  • the direction of swiveling of the antenna is basically in line with a longitudinal axis of the connection member or perpendicular to the connection member, generally about an axis that is perpendicular to the longitudinal axis of the connection member. This results in a system in which rotation of the antenna is limited.
  • Taiwan Pat. No. M317082 further includes a positioning button and a spring biased by the positioning button. The positioning button abuts against an end of the connection member in order to cause the antenna to be retained in position.
  • swivel antenna is of the formed disclosed in Taiwan Pat. No. M299931 .
  • the antenna includes a spring and a metallic buffer sustained by the spring.
  • the metallic buffer frictionally upholds a bottom of the antenna portion in order to cause the antenna portion to be retained in a desired position.
  • the swivel antenna may still be oriented in limited angles.
  • a wireless transceiver carrying a double rotary antenna includes a body and the antenna.
  • the body includes a housing and a circuit board disposed in the housing.
  • the housing of the body has a receiving portion and a connecting portion.
  • the receiving portion defines an opening in a sidewall.
  • the connecting portion is to be detachably plugged into a slot of a computer.
  • the antenna includes a sleeve, a shaft, a spring, a pivot portion and an antenna portion.
  • the sleeve is disposed in the receiving portion, electrically connected to the circuit board, and has a first retaining portion therein.
  • the shaft is received in the sleeve and capable of linearly moving and rotating, and has a first end extending outside the sleeve and a second end formed with a second retaining portion.
  • the spring is received around the shaft and biased between the first and second retaining portions.
  • the pivot portion is joined with the first end of the shaft and capable of swinging with respect to the shaft in order to drive the shaft to move linearly.
  • the antenna portion is secured on an end of the pivot portion and configured to transmit or receive wireless signals.
  • the antenna Due to the rotatable shaft within the sleeve, the antenna is allowed to rotate 360 degrees with respect to the body. On the other hand, the antenna is allowed to swing or bend 90 degrees as a result of the swingable pivot portion and the shaft. Hence the double rotary antenna is designed to enable 360-degree rotation and 90-degree bending, so one can more easily orient it in the direction needed. Moreover, because of the spring, the shaft exerts a force on the pivot portion to retain the antenna in desired rotary position.
  • a wireless transceiver having a body 1 and an antenna 2 according to the preferred embodiment of the present invention.
  • the body 1 includes a housing 10 and a circuit board 11.
  • the housing 10 of the body 1 includes a receiving portion 12 and a connecting portion 13.
  • the receiving portion 12 defines an opening 15 in a sidewall 14 thereof.
  • the opening 15 is in communication with the inside of the receiving portion 12.
  • the connecting portion 13 of the housing 10 is to be detachably plugged into a slot of a computer (not shown).
  • the circuit board 11 is disposed in the housing 10 and includes an elastic conductive plate 16.
  • the antenna 2 includes a sleeve 20, a shaft 30, a spring 40, a pivot portion 50, an antenna portion 60 and a casing 70.
  • the sleeve 20 of the antenna 2 is formed with a shoulder 21 outside to be lodged in a recess of the receiving portion 12 of the body 1.
  • the sleeve 20 is further formed inside with a first retaining portion 22 which defines a through hole in the central part.
  • the shaft 30 is received in the sleeve 20 and is capable of linearly moving and rotating relative to the sleeve 20. Furthermore, the shaft 30 has a first end 31 and a second end 32. The first end 21 passes through the sleeve 20 and the opening 15 and extends outside the sleeve 20. The second end 32 is formed with a second retaining portion 33.
  • the spring 40 is received around the shaft 30 and biased between the first and second retaining portions 22, 33.
  • the pivot portion 50 defines a joint groove 51 and a separate annular groove 52.
  • the joint groove 51 is provided to receive the first end 31 of the shaft 30.
  • a stem 53 is applied to pass through the pivot portion 50 and the first end 31 of the shaft 30 so as to enable the pivot portion 50 to rotate about the stem 53 with respect to the shaft 30.
  • the antenna portion 60 is secured on an end of the pivot portion 50 and is formed thereon with an antenna pattern 61 to transmit or receive wireless signals.
  • the antenna pattern 61 may be designed in any needed shape.
  • the casing 70 of the antenna 2 includes a shell 71 and a cover 72 coupled with the shell 71.
  • the shell 71 defines a room 73 therein to receive the pivot portion 50 and the antenna portion 60.
  • the cover 72 covers the room 73.
  • the shell 71 and the cover 72 both were formed with a latch 74 to be lodged in the annular groove 52 of the pivot portion 50.
  • the shell 71 defines a first notch 75 in a sidewall to receive the shaft 30.
  • the cover 72 defines a second notch 76 in communication with the first notch 75 of the shell 71. That is, the shell 71 and the cover 72 together define a notch in a corner of the casing 70. The notch is in communication with the room 73.
  • the sleeve 20, the shaft 30, the spring 40 and the pivot portion 50 are made of metal/conductive material.
  • the antenna pattern 61 of the antenna portion 60 is electrically connected to the pivot portion 50.
  • the elastic conductive plate 16 of the circuit board 11 contacts with a side of the sleeve 20, as shown in FIG. 3 .
  • a positioning bulge 17 is formed on the sidewall 14 of the receiving portion 12 of the body 1.
  • the cover 72 of the casing 70 of the antenna 2 defines a positioning dent 77 to receive the positioning bulge 17 of the body 1.
  • the antenna 2 is allowed to rotate 360 degrees outside the body due to the rotatable shaft 30 within the sleeve 20, as shown in FIG. 4 .
  • FIGS. 5 and 6 illustrate that the antenna 2 swings outwardly to an extended position where the cover 71 abuts at one end against the sidewall 14 of the body 1, and the first end 31 of the shaft 30 is shifted from the second notch 76 of the cover 72 to the first notch 75 of the shell 71.
  • the pivot portion 50 rotates with the shell 71 and pulls the shaft 30 to move linearly while the spring 40 remains biased by the first and second retaining portions 22, 33. Due to the restoring force of the spring 40, the shaft 30 exerts a reverse, pulling force on the pivot portion 50 in order to retrain the antenna 2 in the extended position, perpendicular to the sidewall 14.
  • the casing 70 of the antenna 2 and the housing 10 of the body 1 are designed and shaped as a whole, especially when the casing 70 is in its retracted position.
