Description

electronic communication device

technical field

The invention relates to an electronic communication device, in particular to an electronic communication device which can automatically adjust the position of the antenna when the cover is opened and closed relative to the main body.

Background technique

General electronic communication devices must rely on antennas as transmission interfaces for wireless signal transmission and reception. The antenna is usually arranged outside the electronic communication device to maximize the receiving range of the antenna to achieve a better communication state. Taking a foldable mobile phone as an example, this type of electronic communication device has a cover design. Since the antenna is fixedly arranged outside the electronic communication device, when the cover is opened, the receiving range of the antenna in a specific direction is shielded by the cover.

Please refer to FIGS. 1A-1B at the same time. FIG. 1A shows a schematic view of a traditional electronic communication device, and FIG. 1B shows a schematic view of the electronic communication device in FIG. 1A after being opened. As shown in FIG. 1A , the electronic communication device 10 mainly includes a body 110 , a cover 120 and an antenna 130 . One side of the cover 120 is pivotally connected to one side of the body 110 , and the antenna 130 protrudes from the body 110 . When the electronic communication device 10 is closed, the antenna 130 still maintains a certain signal sending and receiving effect. However, as shown in FIG. 1B , when the cover 120 is opened, the antenna 130 will be shielded by the cover 120 , so that the antenna 130 cannot transmit and receive wireless signals in all directions, resulting in a decrease in the efficiency of transmitting and receiving signals. If the material of the cover 120 is metal, the metal will produce a shielding effect, which is more likely to affect the effect of transmitting and receiving signals of the antenna 120 in this case.

Contents of the invention

In view of this, the object of the present invention is to provide an electronic communication device. When the cover is opened and closed relative to the main body, the transmission mechanism is used to drive the antenna to move, so as to adjust the position of the antenna on the electronic communication device. It is used to reduce the shielding effect of the cover on the antenna, so that the user can use the electronic communication device more effectively.

According to the purpose of the present invention, an electronic communication device is proposed, which includes a body, a cover, an antenna and a transmission mechanism. The cover is pivotally connected to the main body in an openable and closable manner, the antenna is movably arranged on the main body, and the transmission mechanism is arranged between the cover and the antenna. When the cover is opened, the cover drives the transmission mechanism so that the transmission mechanism moves the antenna away from the main body. When the cover is closed, the cover drives the transmission mechanism, so that the transmission mechanism moves the antenna close to the body.

According to another object of the present invention, an electronic communication device is provided, which includes a body, a cover, an antenna, a rack, a first gear, a second gear and a third gear. The cover is pivotally connected to the main body in an openable and closable manner, and the antenna is movably configured on the main body. The rack is connected to the antenna and can enter and exit the body. The first gear is fixed on the cover body, and the second gear is rotatably arranged on the body for meshing with the first gear. Wherein the pitch diameter of the second gear is smaller than the pitch diameter of the first gear. The third gear is coaxially fixed on the second gear for meshing with the rack, wherein the pitch diameter of the third gear is larger than that of the second gear. When the cover is lifted away from the body in a first direction, the first gear also rotates in the first direction. At this moment, the first gear drives the second gear to rotate in a second direction, wherein the second direction is opposite to the first direction. The third gear also rotates toward the second direction, so that the third gear drives the rack to move toward a third direction to move the antenna away from the main body. When the cover is folded to the body in the second direction, the first gear also rotates in the second direction. At this time, the first gear drives the second gear to rotate in the first direction, and the third gear also rotates in the first direction. The third gear drives the rack to move in a fourth direction, and the fourth direction is opposite to the third direction, so as to move the antenna closer to the body.

Detailed ways

The invention proposes an electronic communication device, which uses a transmission mechanism to enable the antenna to have a moving function to adjust the position of the antenna in the electronic communication device to solve the problem of the antenna being covered.

Please refer to FIG. 2 and FIG. 3A to FIG. 3B at the same time. FIG. 2 is a schematic diagram of an electronic communication device according to a preferred embodiment of the present invention. FIG. 3A is a first schematic diagram of some components of the electronic communication device in FIG. 2 , FIG. 3B is a second schematic diagram of some components of the electronic communication device shown in FIG. 2 . As shown in FIG. 2 , the electronic communication device 20 includes a body 210 , a cover 220 , an antenna 230 , and a transmission mechanism 240 . The cover 220 is pivotally connected to the main body 210 in an openable and closable manner, and the antenna 230 is movably configured on the main body 210 . The transmission mechanism 240 is disposed between the cover 220 and the antenna 230 . When the cover 220 is opened, the cover 220 drives the transmission mechanism 240 so that the transmission mechanism 240 moves the antenna 230 away from the main body 210 . When the cover 220 is closed, the cover 220 drives the transmission mechanism 240 so that the transmission mechanism 240 moves the antenna 230 to approach the body 210 .

The design of the transmission mechanism 240 will be described with reference to FIGS. 3A-3B , but the technology of this embodiment is not limited thereto. The transmission mechanism 240 mainly includes a rack 241 , a first gear 242 , a second gear 243 ( FIG. 3B ) and a third gear 244 . One end of the rack 241 is connected to the antenna 230 and is movably disposed on the body 210 , so that the rack 241 can be moved out of or into the body 210 . As shown in Figure 3A, the first gear 242 is fixed on one end of the cover 220, and the rotation axis X of the first gear 242 and the cover 220 are consistent, so when the cover 220 is opened, the first gear 242 also follows the cover. Body 220 rotates. The second gear 243 and the third gear 244 are rotatably disposed on the body 210 , and their structure is shown in FIG. 3B . The second gear 243 and the third gear 244 are coaxially fixed together. Wherein the second gear 243 meshes with the first gear 242 , and the third gear 244 meshes with the rack 241 .

In the design of the transmission mechanism 240 , the second gear 243 and the third gear 244 can also be replaced by only one gear, so that the gear meshes with the first gear 242 and the rack 241 at the same time. Wherein, the pitch diameter of this gear may be the same as or different from that of the first gear 242 .

Please refer to FIG. 4 , which shows a schematic diagram of the operation of the electronic communication device in FIG. 2 . As shown in FIG. 4 , when the cover (not shown) is lifted away from the main body (not shown) in the first direction R ₁ , the first gear 242 also rotates with the cover in the first direction R ₁ . At this time, the second gear 243 meshing with the first gear 242 rotates in the second direction R ₂ , wherein the second direction R ₂ is opposite to the first direction R ₁ . Since the third gear 244 is coaxially fixed with the second gear 243, the third gear 244 also rotates in the second direction _R2 , and the third gear 244 simultaneously drives the rack 241 and the antenna 230 to move in the third direction _S1 , so that The antenna 230 is away from the body. Conversely, if the first gear 242 rotates in the second direction _R2 , the second gear 243 and the third gear 244 will rotate in the first direction _R1 , and simultaneously drive the rack 241 and the antenna 230 to the fourth direction _S2. Move to make the antenna 230 move closer to the body.

Preferably, the pitch diameter of the first gear 242 is larger than the pitch diameter of the second gear 243 in design. When the first gear 242 rotates, the rotating speed of the meshing second gear 243 can be greater than the rotating speed of the first gear 242 . At the same time, the pitch diameter of the third gear 244 is larger than the pitch diameter of the second gear 243 . When the second gear 243 and the third gear 244 rotate at the same speed, the third gear 244 drives the rack 241 to move a relatively large distance. That is to say, the antenna 230 can be moved a large distance as long as the cover 220 is turned over a small angle.

Since the antenna 230 is a movable component in the electronic communication device 20 , its electrical connection design is different from that of general electronic communication devices. In terms of design, as shown in FIG. 4 , the electronic communication device 20 further includes a metal dome 250 , and the rack 241 is made of metal material. One end of the metal dome 250 is electrically connected to a printed circuit board (not shown in the figure) in the electronic communication device 20 , and the other end of the metal dome 250 is electrically connected to the rack 241 . During the movement of the rack 241 , the metal domes 250 all abut against the rack 241 to maintain the state of electrical connection. Wherein, the upper half structure of the rack 241 electrically connected with the metal dome 250 may be metal or metal alloy, and the lower half structure of the rack 241 may be an insulating material.

Please refer to FIG. 5 , which is a schematic view of the folded electronic communication device in FIG. 2 . As shown in FIG. 5 , in the electronic communication device 20 , through the design of the transmission mechanism 240 , when the cover 220 is opened, the rack 241 is driven out of the main body 210 and the antenna 230 is moved away from the cover 220 . When the cover 220 is completely opened, the antenna 230 moves to a position farthest from the main body 210 . Similarly, when the cover 220 is closed, as shown in FIG. 2 , the rack 241 is moved into the body 210 , and the antenna 230 returns to an original state.

In the electronic communication device disclosed in the above-mentioned embodiments of the present invention, when the cover is opened and closed relative to the main body, the position of the antenna in the electronic communication device can be automatically adjusted through the combination of the gear and the rack in the transmission mechanism. When the user uses the electronic communication device, the antenna is automatically moved out of the range covered by the cover, so that the transmitting and receiving effect of the antenna is not affected, and all-round signal transmission and reception is achieved.

In summary, although the present invention has been disclosed in conjunction with the above preferred embodiment, it is not intended to limit the present invention. Those skilled in the art of the present invention can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the protection scope of the present invention should be defined by the appended claims.
