Description

clamshell electronics

technical field

The present invention relates to an electronic device, and in particular to an audio source element of the electronic device.

Background technique

The sound source amplifier equipped with a traditional notebook computer is usually fixedly buried in the computer case, and a plurality of holes are opened corresponding to the sound source amplifier on the computer case, so that the sound output by the sound source amplifier can pass through the computer case. The hole is broadcast for the user to listen to. However, since the sound output by the above-mentioned sound source amplifier is transmitted from the computer casing, it does not have any sound directivity, thus resulting in poor sound propagation effect.

In view of this, the industry has introduced audio amplifiers that can be directed toward the user to provide sound directivity. However, this design makes the user often need to manually operate the audio source amplifier to face the direction of the user when listening to music. In this way, not only the convenience of the notebook computer is reduced, but also the purchase desire of the user is reduced.

Therefore, the object of the present invention is to provide a clamshell electronic device.

According to one embodiment of the present invention, a clamshell electronic device includes a first body, a second body, a first pivot, an audio module disposed on the second body, a second pivot, a cam, a follower, a card Latch and elastic element. Wherein, the first pivot pivotally connects the first body and the second body. The second pivot pivotally connects the audio module and the second body. The cam is coupled to the first pivot. The follower contacts the cam. The latch locks the audio module and connects the driven part. The elastic element includes two ends, one end is against the second body, and the other end is against the audio module.

When the user opens the first body and the second body, the first pivot pivotally connecting the first body and the second body will drive the cam to rotate, so that the driven portion contacting the cam will be displaced. This displacement will cause the latch to release the audio module, so that the audio module is pushed out of the second body by the elastic element and faces the user.

In order to clearly illustrate the structure and operation of the audio module 140 , in FIGS. 2 to 6 , both the first body 110 and the second body 120 are omitted.

As shown in FIG. 3 , the notebook computer 100 of this embodiment may further include a second pivot 150 , a cam 160 , a driven part 170 , a latch 180 and an elastic element 190 . Wherein, the second pivot 150 pivotally connects the audio module 140 and the second body. The cam 160 is coupled with the first pivot 130 . The follower 170 contacts the cam 160 . The latch 180 is engaged with the audio module 140 and connected with the driven part 170 . The elastic element 190 has two ends 192 / 194 , one end 192 is against the second body, and the other end 194 is against the audio module 140 .

Specifically, the cam 160 and the first pivot 130 may be coupled to each other through various transmission mechanisms (eg, gear transmission mechanisms). For example, the notebook computer 100 in FIG. 3 uses a gear transmission mechanism to couple the cam 160 and the first pivot 130 . The aforementioned gear transmission mechanism may include a first gear 210 and a second gear 220 meshing with each other. Wherein, the first gear 210 is connected to the first pivot 130 , and the second gear 220 is connected to the cam 160 .

In addition, the driven part 170 can be directly connected to the latch 180 , or indirectly connected to the latch 180 through other transmission mechanisms, as long as it can be reliably linked with the latch 180 . Taking FIG. 3 as an example, the driven portion 170 directly protrudes from the latch 180 to the cam 160 .

The latch 180 described above can engage the audio module 140 in various ways. Taking FIG. 3 as an example, the audio module 140 may include a protrusion 142 . The latch 180 can include a hook 182 suitable for hooking the post 142 of the audio module 140 . During manufacture, the manufacturer can pivotally connect the latch 180 to the second body through a pivot pin 230 , and separate the hook 182 and the driven portion 170 at two ends of the pivot pin 230 .

In this embodiment, the elastic element 190 can be a torsion spring. The torsion spring mentioned above can be sleeved on the second pivot 150 to save the internal space of the notebook computer 100 . It should be understood that the above-mentioned torsion spring is only an example and is not intended to limit the present invention, and various other springs, such as compression springs, tension springs or springs, can also be used as elastic elements. Those with ordinary knowledge in the technical field to which the present invention belongs should choose flexibly according to actual needs.

The operation of the notebook computer 100 of this embodiment will be described in detail below by taking FIGS. 4-6 as examples.

As shown in FIG. 4 , when the notebook computer 100 is closed, since the latch 180 engages the audio module 140 , the audio module 140 will be folded into the second body and compress the elastic element 190 to store elastic potential energy. That is to say, since the elastic element 190 is in a compressed state at this time, the audio module 140 will bear the pre-force of unidirectional rotation (for example: counterclockwise direction R1 ) at this time.

When the user opens the first body and the second body, the first pivot 130 pivotally connecting the first body and the second body will drive the first gear 210 to rotate in the clockwise direction R2. At this time, since the first gear 210 and the second gear 220 are meshed with each other, the second gear 220 will drive the cam 160 to rotate in the counterclockwise direction R3 to push the driven part 170 to move downward.

In order to ensure that the first body is linked with the first pivot 130 , the manufacturer may need to install a connecting rod 135 at the first pivot 130 as needed. The connecting rod 135 can connect the first body and the first pivot 130 so that when the first body rotates relative to the second body, the first pivot 130 can rotate together.

It should be understood that the above-mentioned connecting rod 135 is only an example, and is not intended to limit the present invention. In other embodiments of the present invention, the first pivot can also be directly connected to the first body without additional connecting rods. Those with ordinary knowledge in the technical field to which the present invention belongs should choose flexibly according to actual needs.

When the driven part 170 is pushed downward by the cam 160 , the hook 182 will move upward synchronously, and loosen the boss 142 of the audio module 140 (as shown in FIG. 5 ).

Once the latch 180 is released from the audio module 140 , the elastic potential energy released by the elastic element 190 will push the audio module 140 to rotate in the clockwise direction R1 and stand up. That is to say, the audio module 140 will be pushed out of the second body by the elastic member 190 at this time, and face the user (as shown in FIG. 6 ).

The above-mentioned "audio module 140 facing the user" should be interpreted as: "the exterior panel 144 of the audio module 140 faces the user." At this time, the sound unit inside the audio module 140 will face the user through the exterior trim panel 144, so as to surely emit sound toward the user.

In some cases, the audio module 140 may shake and become unstable after standing up. In order to prevent the audio module 140 from being shaken and unstable, the manufacturer may choose to install an actuating mechanism 260 at the second pivot 150 . Specifically, the aforementioned actuating mechanism 260 may include a fastening slot 262 , an actuating member 264 and an actuating elastic body 266 . Wherein, the fastening groove 262 is disposed on the sidewall of the second pivot 150 . The actuating elastic body 266 is connected to the actuating member 264 and a fixed end (for example: the second body), so as to force the actuating member 264 against the side wall of the second pivot 150 . In this way, when the audio module 140 is rotated to stand up, the above-mentioned actuating member 264 will fall into the fastening groove 262 to restrict the second pivot 150 from further rotation (as shown in FIG. 6 ).

In this embodiment, the above-mentioned actuating elastic body 266 can be indirectly connected to the actuating member 264 through a slider 268 . However, this does not limit the present invention. In other embodiments of the present invention, the actuating elastic body can also be directly connected to the actuating member. Those with ordinary knowledge in the technical field to which the present invention belongs should choose flexibly according to actual needs.

Although FIGS. 2-6 illustrate the actuating elastic body 266 as a tension spring, this does not limit the present invention, and other types of springs, such as compression springs, torsion springs or shrapnel, can also be used as actuating springs. Dynamic elastic body. Those with ordinary knowledge in the technical field to which the present invention belongs should choose flexibly according to actual needs.

It should be understood that the actuating mechanism 260 described above is only an example and is not intended to limit the present invention, and other various multi-stage adjustment mechanisms can also be used to replace the actuating mechanism 260 . Those with ordinary knowledge in the technical field to which the present invention belongs should choose flexibly according to actual needs.

In addition, the notebook computer 100 of this embodiment may further include a pressing part 250 . The pressing portion 250 can be connected to the sidewall of the first pivot 130 . In this way, when the user closes the first body and the second body, the pressing part 250 can press the audio module 140 back into the second body.

Specifically, when the user closes the first body and the second body, the pressing part 250 will press against the audio module 140, so as to force the audio module 140 to turn back to the second body along the clockwise direction R4 (as shown in Figure 6- 4). At the same time, the elastic element 190 will also be compressed by the audio module 140 to store elastic potential energy for the next operation.

Although FIGS. 1-6 all show the pressing part 250 as a rod-shaped member, this does not limit the present invention. In other embodiments of the present invention, the pressing portion can also be the shell of the first body. That is to say, the user can directly press the audio module back into the second body by using the shell of the first body without additionally installing a rod-shaped pressing part. Those with ordinary knowledge in the technical field to which the present invention belongs should choose flexibly according to actual needs.

In addition, in order to allow the latch 180 to automatically reset the snap-on audio module 140, the manufacturer may choose to install a reset elastic body 240 on the latch 180 (as shown in FIGS. The body and the latch 180 are used to maintain the relative position of the latch 180 and the second body.

Specifically, the above-mentioned restoring elastic body 240 may be a torsion spring. In this way, when the user opens the first body and the second body, the reset elastic body 240 will twist to store elastic potential energy (as shown in FIG. 2 ). And when the user closes the first body and the second body, the reset elastic body 240 will release the previously stored elastic potential energy, and the latch 180 will bounce back to the original orientation (for example: horizontal), and the audio module 140 (such as Figure 3).

Of course, various other springs can also be used in this embodiment. As the return elastic body, those with ordinary knowledge in the technical field of the present invention should choose it flexibly according to actual needs.

As shown in FIG. 1 , the second body 120 of this embodiment can include a groove 122 , and the groove 122 can accommodate the audio module 140 therein, thereby reducing the thickness of the notebook computer 100 when it is closed. In this embodiment, the above-mentioned groove 122 may be disposed on a side of the second body 120 facing the first body 110 and adjacent to the first pivot 130 . However, this does not limit the present invention. Those skilled in the art of the present invention should flexibly select the embodiment of the groove 122 according to actual needs.

Although the present invention has been disclosed above in terms of implementation, it is not intended to limit the present invention. Any person familiar with this technology can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, this The protection scope of the invention shall be determined by the scope defined in the claims.
