DESCRIPTION OF THE PREFERRED EMBODIMENT

In the following description, the present invention will be explained with reference to embodiments thereof. However, these embodiments listed herein are not intended to limit the present invention to any specific examples, embodiments, environment, applications or particular implementations described in these exemplary embodiments. Therefore, description of these exemplary embodiments is only for purpose of illustration rather than to limit the present invention.

As shown inFIG.1, in a method of folding and extending an antenna structure100capable of transmitting a WiGig band according to the present invention, the antenna structure100is optimized in the following steps: first, mounting a WiGig module200capable of transmitting a WiGig band within a base300, as shown in step A1; next, pivotally arranging the antenna structure100on the base300, as shown in step A2; and folding (i.e., storing) or extending (i.e., opening or spreading outwardly) the antenna structure100relative to the base300to correspondingly reduce or increase the antenna structure100for transmitting and receiving a valid range of a wireless signal based on the WiGig technology.

As shown inFIG.2AtoFIG.2D, in a preferred embodiment of the present invention, the antenna structure100comprises two body portions110, and each of the two body portions110has a pivoting end112and a signal transceiving end114opposite to the pivoting end112. In other words, the pivoting end112and the signal transceiving end114are respectively disposed at two opposite ends of the body portion110. Each of the pivoting ends112is pivotally disposed on the base300at a first specific angle SA1with respect to a horizontal plane, and each of the signal transceiving ends114is inclined downward by a second specific angle SA2with respect to the body portion110and disposed away from the body portion110. By the special arrangement of the aforesaid first specific angle SA1and the second specific angle SA2, gains can be obtained by the valid range for transceiving the wireless signal by the antenna structure100of this application, thereby reducing the probability of the occurring of signal dead corners.

Referring again toFIG.2AtoFIG.2B, based on the above arrangements, when the antenna structure100is folded with respect to the base300, the antenna structure100is adapted to exhibit an integrated appearance with the base300, thereby achieving the effect of being stored and carried conveniently.

As shown inFIG.2CtoFIG.2D, when the antenna structure100is extended relative to the base300, the two body portions110are adapted to rotate a third specific angle SA3outwardly relative to the base300so that the signal transceiving range with the forward direction as the main direction and the left-right direction as the auxiliary direction initially is extended to a signal transceiving range toward the forward, left-right and backward directions, and the signal transceiving range at this point instead takes the left-right direction as the main direction and the forward and backward directions as the auxiliary directions.

It shall be particularly appreciated that, although not shown in the aforesaid drawings, the aforesaid WiGig module200performs relevant signal transmission with the antenna structure100via connection of physical lines, as shall be readily appreciated by those of ordinary skill in the art. Moreover, the aforesaid base300is assumed to be disposed on the head of a user, but it is not limited thereto. The signal transmission relationships between the WiGig module200and the antenna structure100described above are also applicable to the following embodiments of the present application.

FIG.3AtoFIG.3Bare taken as an example hereinafter to illustrate the wireless signal transmission state between the antenna structure100in the folded state or extended state of the present invention and a signal transmitting end600.

First referring toFIG.3A,FIG.3Amay be regarded as a special configuration of the antenna structure100inFIG.2AtoFIG.2Bthat is folded on the base300without the first specific angle SA1and the second specific angle SA2. In this case, because the signal transceiving end114is in the folded state with respect to the base300, and a front surface of the signal transceiving end114that is configured to receive and transmit wireless signals directly faces the signal transmitting end600(i.e., a signal transceiving range with the forward direction as the main direction and the left-right direction as the auxiliary direction), the signal transceiving end114in the folded state is quite suitable for use by users in scenarios not requiring intense actions, e.g., static games and film viewing.

Similarly,FIG.3Bmay be regarded as a special configuration of the antenna structure100inFIG.2CtoFIG.2Dthat is extended on the base300without the first specific angle SA1and the second specific angle SA2. In this case, because the signal transceiving end114is in the outwardly extended state with respect to the base300so that a front surface of the signal transceiving end114that is configured to receive and transmit wireless signals is toward the left and right sides of the base station300, and left and right sides of the front surface of the signal transceiving terminal114may also have the function of transceiving wireless signals (i.e., a signal transceiving range with the left-right direction as the main direction and the forward and backward directions as the auxiliary directions), the transceiving range of the signal transceiving end114at this point is at a best reception position. In other words, even if the user is performing actions such as turning back, bowing, raising his/her head or other activities, one of the two signal transceiving ends114can still maintain the directivity and the connection with respect to the signal transmitting end600, thereby ensuring that the reception of the data flow will not be influenced, and preventing operation delay caused by insufficient signal strength or errors in data flow reception during the data transmission by the user.

On the other hand, through the computation of an in-built signal processor, the signal transceiving end114in the extended state may also automatically detect and adjust the signal reception amount. For example, when the signal reception amount of one of the two signal receiving ends114is reduced due to excessively large movement of the body (e.g., turning the head to the left/right sides) of the user, the antenna structure100of the present invention will automatically switch the reception strength of another signal receiving end114to increase the signal reception amount, thereby ensuring the connection quality and preventing errors in the reception of data flow.

As shown inFIG.4, the present invention additionally provides a method of folding and extending an antenna structure100capable of transmitting a WiGig band, and the method performs optimization on the antenna structure100via the following steps: first, as shown in step B1, disposing the antenna structure100on a head-mounted wireless transmission display device400; and next, as shown in step B2, folding or extending the antenna structure100with respect to the head-mounted wireless transmission display device400to correspondingly reduce or increase the antenna structure100for transceiving a valid range of a wireless signal based on the WiGig technology.

In detail, in the aforesaid method, in order to ensure that no obscuration or reception error occurs between the signal transmitting end600and the signal transceiving ends114while taking the directivity between the signal transmitting end600and the signal transceiving ends114into consideration, the signal transceiving end114of the antenna structure100of the present invention may be arranged in the following two configurations, which are respectively as follows: “(1) the two signal transceiving ends114are arranged at left and right sides of the head of a user500with respect to the head of the user500” and “(2) the two signal transceiving ends114are arranged at front and back sides of the head of the user500with respect to the head of the user500”.

The aspect where “(1) the two signal transceiving ends114are arranged at left and right sides of the head of a user500with respect to the head of the user500” may be further divided into a first embodiment shown inFIG.5AtoFIG.5Cand a second embodiment shown inFIG.6AtoFIG.6C.

First, as depicted inFIG.5AtoFIG.5C, an aspect where the two body portions110of the antenna structure100are respectively arranged at left and right sides of a display screen410of the head-mounted wireless transmission display device400is shown. As shown inFIG.5AtoFIG.5C, when the two body portions110of the antenna structure100are respectively arranged at left and right sides of the display screen410of the head-mounted wireless transmission display device400, and the signal transceiving end114of each of the body portions110is extended outward, a first distance D1between the two signal transceiving ends114is greater than a width of the display screen410. In this way, when the display screen410swings to the left and right sides, one of the two signal transceiving ends114may still maintain the communication with the front signal transmitting end600even if communication between the other one of the two signal transceiving ends114and the front signal transmitting end600is blocked, thereby maintaining the stability during the data flow reception.

As depicted inFIG.6AtoFIG.6C, an aspect where the two body portions110of the antenna structure100are respectively arranged at left and right sides of an overhead device420of the head-mounted wireless transmission display device400is shown. As shown inFIG.6AtoFIG.6C, when the two body portions110of the antenna structure100are respectively arranged at left and right sides of the overhead device420of the head-mounted wireless transmission display device400, and the signal transceiving end114of each of the body portions110is extended outward, a second distance D2between the two signal transceiving ends114is greater than a head width of the user500. In this way, when the display screen410swings to the left and right sides, one of the two signal transceiving ends114may also maintain the communication with the front signal transmitting end600even if communication between the other one of the two signal transceiving ends114and the front signal transmitting end600is blocked, thereby maintaining the stability during the data flow reception.

It shall be noted that, although not shown in the figures, the antenna structure100in the embodiments ofFIG.5AtoFIG.5CandFIG.6AtoFIG.6Cmay still have special arrangements involving the aforesaid first specific angle SA1, the second specific angle SA2and the third specific angle SA3or the like, and meanwhile have actions of automatically switching the signal reception strength, thereby preventing errors in the reception of the data flow.

The aspect where “(2) the two signal transceiving ends114are arranged at front and back sides of the head of the user500with respect to the head of the user500” may be further divided into a third embodiment ofFIG.7A, a fourth embodiment ofFIG.7Band a fifth embodiment ofFIG.7C.

In detail, as shown in the third embodiment ofFIG.7A, when the user500is playing a game requiring less intense actions via the head-mounted wireless transmission display device400, the signal transceiving end114of the antenna structure100may be folded on the overhead device420to receive the data flow (i.e., the signal transceiving end114is in the closed state). In this case, the stability in data reception can be effectively ensured simply by disposing the two signal transceiving ends114slightly higher than the head of the user500. Moreover, in the embodiment ofFIG.7A, the two signal transceiving ends114may be further disposed at corresponding positions indicated by C1, C2and C3respectively to satisfy the minimum signal reception requirement during static activities.

As shown in the fourth embodiment ofFIG.7B, when the user500is to perform relatively intense actions, the antenna structure100may be extended upward from the initial position indicated by C3ofFIG.7Athrough stretching (i.e., the antenna structure100is in the spread state) so that the two signal transceiving ends114are respectively disposed at the front and back sides of the head of the user500at a specific height above the head of the user500, thereby obtaining a better signal reception range. The aforesaid specific height is preferably 70 mm, but it is not limited thereto.

As shown in the fifth embodiment ofFIG.7C, the two signal transceiving ends114may also be extended respectively forward and backward so that the two signal transceiving ends114are across the head of the user500and disposed with a distance between the two signal transceiving ends114being larger than a width of the head of the user500in the front-back direction, thereby achieving the best effect of the signal reception coverage.

In another preferred embodiment of the antenna structure100of the present invention shown inFIG.8, when the user500is wearing the head-mounted wireless transmission display device400, each of the two signal transceiving ends114forms an angle of θ1inclining upward and outward with respect to a plumb line, and the angle θ1is preferably 15 degrees to 20 degrees. Each of the two signal transceiving ends114may also form an angle of θ2inclining forward and downward with respect to a horizontal line, and the angle θ2is preferably designed to be 45 degrees so that the received signal range has the best effect even when the user wearing the head-mounted wireless transmission display device10performs intense activities.

The present invention also claims an antenna structure capable of transmitting a WiGig band. In the embodiment as shown inFIG.2AtoFIG.2D, an antenna structure100capable of transmitting a WiGig band comprises two body portions110, each of the two body portions110has a pivoting end112and a signal transceiving end114opposite to the pivoting end112. Each of the pivoting ends112is pivotally disposed on a base300at a first specific angle SA1with respect to a horizontal plane, and each of the signal transceiving ends114is inclined downward by a second specific angle SA2with respect to the body portion110and disposed away from the body portion110.

Similarly, in the embodiments shown inFIG.5AtoFIG.5C,FIG.6AtoFIG.6CandFIG.7AtoFIG.7C, the antenna structure100may also be pivotally disposed on a head-mounted wireless transmission display device400. Since the embodiment where the antenna structure100is pivotally disposed on the head-mounted wireless transmission display device400has been described in detail in the above paragraphs, this will not be further described herein.

It shall be appreciated that, the aforesaid first specific angle SA1is preferably between 0˜20 degrees, and the second specific angle SA2is preferably between 0˜45 degrees, thereby achieving the best signal reception effect in the folded state.

Additionally, when the antenna structure100is extended relative to the base300or the head-mounted wireless transmission display device400, the two body portions110are adapted to rotate a third specific angle SA3outwardly relative to the base300or the head-mounted wireless transmission display device400, and the third specific angle SA3is between 0 and 60 degrees, thereby achieving the best signal reception effect in the extended state.

According to the above description, through the special antenna structure100and the method of folding and extending the antenna structure100claimed by the present invention, when a WiGig module200capable of transmitting a WiGig band is used to perform data flow transmission of the head-mounted wireless transmission display device400, e.g., data flow transmission applicable in the fields of VR, AR or MR, the coverage of the signal reception range can be ensured by disposing the two signal transceiving ends114of the antenna structure100respectively at the left and right sides of the head of the user500or disposing the two signal transceiving ends114of the antenna structure100respectively at the front and back sides of the head of the user500even if the WiGig module200is limited in directivity, thereby effectively ensuring the stability in wireless transmission of the data flow and meanwhile making the antenna structure100convenient to be carried by the users.
