Abstract

The invention relates to a supporting device of an electronic device, which comprises a base, a fixing plate capable of accommodating the electronic device, a supporting frame and a rotating module. The fixed plate covers the base and can rotate relative to the base, and the supporting frame covers the fixed plate and can rotate relative to the fixed plate. The rotating module is respectively connected to the base, the fixing plate and the supporting frame. When the fixing plate rotates relative to the base and the fixing plate drives the support frame to rotate by a preset angle, the support frame rotates relative to the fixing plate and does not rotate synchronously with the fixing plate in response to the operation of the rotating module. Therefore, the user only needs to lift or cover the fixing plate without operating the support frame.

Wherein, when the support frame 32 is driven to rotate in the first direction D1, the second connecting member 3313 is driven to rotate relative to the first shaft body 3311, and the second connecting member 3313 drives the first cam 3314 to also move toward The rotation in the first direction D1 makes the first protruding portion 3314B of the first cam 3314 rotate along the edge of the first concave portion 3315A of the second cam 3315 to form a situation where the first cam 3314 abuts against the second cam 3315 .

The fixing plate 31 continuously drives the supporting frame 32 to rotate in the first direction D1. When the fixing plate 31 drives the supporting frame 32 to rotate at a predetermined angle A, the first raised portion 3314B leaves the first concave portion 3315A and contacts the second raised portion 3315C, At this time, the force of the first cam 3314 pushing against the second cam 3315 is maximum, so that the support frame 32 connected to the second connecting member 3313 is separated from the fixing plate 31 and can rotate relative to the fixing plate 31 . When the fixed plate 31 drives the support frame 32 to rotate the preset angle A and the angle between the fixed plate 31 and the base 30 enters the free angle range, the first cam 3314 pushes against the second cam 3315 so that the first raised portion 3314B passes through The second protruding portion 3315C moves toward the second concave portion 3315B, and the supporting frame 32 rotates relative to the fixing plate 31 in response to the sliding of the second cam 3315 until the supporting frame 32 contacts the working surface T. In this preferred embodiment, the free included angle ranges from 120 degrees to 160 degrees.

On the other hand, when the fixed plate 31 and the support frame 32 rotate in the first direction D1 relative to the base 30, the fixed plate 31 drives the fourth connecting member 3323, and the fourth connecting member 3323 drives the third cam 3324 to rotate, The rotating third cam 3324 abuts against the fourth cam 3325 to make the fourth cam 3325 slide on the second shaft 3321 . The fourth cam 3325 slides against the second elastic member 3326 so that the second elastic member 3326 can generate a second elastic force. Wherein, with the rotation of the fixing plate 31, the third raised portion 3324B of the third cam 3324 rotates to abut against the third concave portion 3325A, the fourth raised portion 3325C and the fourth concave portion 3325B of the fourth cam 3325 in sequence, so that The fourth cam 3325 slides on the second shaft body 3321 in response to the abutment of the third cam 3324, and the second elastic member 3326 provides a second elastic force of different strengths in response to the sliding of the fourth cam 3325, so as to provide support for the The supporting device 3 of the electronic device can prevent the supporting device 3 of the electronic device from overturning due to the weight of the electronic device 4 .

It should be noted that in the present invention, when the angle between the fixed plate 31 and the base 30 enters a free angle range, the fixed plate 31 and the supporting frame 32 can rotate independently without interfering with each other. Wherein, the angle range of the free angle range is related to the design of the receiving groove 3221 of the support frame 32, the farther the distance between the first limiting wall 3222 and the second limiting wall 3223, and the angle between the two The larger is, the larger the angle range of the free angle range is, and vice versa. Therefore, the accommodating groove 3221 of the support frame 32 can be designed according to requirements, so as to obtain the required free angle range.

After the user completes the operation of the electronic device 4, the user wishes to return the supporting device 3 of the electronic device from the operating state of FIG. 6 to the storage state of FIG. 31 on the electronic device 4), so that the fixed plate 31 rotates to the second direction D2 relative to the base 30, because the angle between the fixed plate 31 and the base 30 is within the free angle range, the fixed plate 31 still does not drive the support The frame 32 rotates. When the fixed plate 31 continues to rotate in the second direction D2 and the angle between the fixed plate 31 and the base 30 is out of the free angle range, the protruding part 316 pushes against the second limiting wall 3223 and starts to drive the support frame 32 to move forward. The second direction D2 rotates.

When the fixed plate 31 rotates relative to the base 30 in the second direction D2, and the fixed plate 31 drives the support frame 32 to rotate the preset angle A, the first cam 3314 abuts against the second cam 3315, and the body originally located in the second concave portion 3315B The first cam 3314 starts to move and moves toward the first concave portion 3315A through the second raised portion 3315C, so that the second cam 3315 slides on the first shaft body 3311, and the support frame 32 moves relative to the sliding of the second cam 3315 The fixed plate 31 rotates. At this time, the support frame 32 changes from the state of being separated from the fixing plate 31 to the state of being in close contact with the fixing plate 31 , and can push the fixing plate 31 to rotate in the second direction D2 according to the sliding force of the second cam 3315 . Thereby, the supporting device 3 of the electronic device can return to the storage state shown in FIG. 7 .

According to the above, the supporting device of the electronic device of the present invention can control the opening and closing of the fixed plate and the support frame through the operation of the rotating module, which allows the user to control the operation of the fixed plate and the support frame only by lifting or covering the fixed plate , without operating the fixed plate and the support frame separately. Wherein, before the fixed plate rotates to a specific angle and has not yet entered the free angle range, the fixed plate and the supporting frame can rotate synchronously. After the fixed plate is rotated to a specific angle, the support frame can be rotated relative to the fixed plate without the need for the user to lift or cover the support frame. Thereby, the user's operation can be simplified. In addition, depending on the setting of the supporting frame, the supporting force can be strengthened by contacting the supporting frame with the working surface. On the other hand, through the operation of the second rotating mechanism, the fixing plate can obtain rotation resistance, so as to prevent the electronic device from colliding with the base.

The above descriptions are only preferred embodiments of the present invention, and are not intended to limit the scope of protection of the present invention. Therefore, all other equivalent changes or modifications that do not deviate from the disclosed spirit of the present invention should be included in the present invention within the scope of protection.
