Detailed Description

Embodiment 1 this embodiment is a method for using an electronic device such as a cell phone. The self weight of a mobile terminal such as a tablet personal computer drives a clamping arm to clamp the strategy support of the equipment.

The gravity bracket of the embodiment shown in fig. 1 comprises a housing 100 formed by covering a bottom shell 101 and a face cover 104, clamping members 200 symmetrically protruding from two sides of the housing 100 in a mirror manner, and a bracket 300 protruding downwards from the middle of the housing 100; when a mobile phone or other terminals are placed in the frame formed by the bracket 300, the face cover 104, the left clamping piece 200 and the right clamping piece 200, and the mobile phone is pressed on the bracket 300 by the self gravity of the mobile phone, the two clamping pieces 200 are clamped towards the middle by using a mechanical structure in the shell, as shown in fig. 6, when the mobile phone and other devices are taken down, the mobile phone cannot recover the folded state shown in fig. 7, and only when a button on the back of the bottom shell 101 is pressed, the gravity support can recover the state shown in fig. 7.

In the present embodiment, the left and right clip members 200 are mirror-symmetrical with respect to each other, and therefore, are symmetrically disposed with respect to both clip members 200 as follows, and are not emphasized.

As shown in fig. 3, the clamp 200 includes a clamp arm 201, the clamp arm 201 has a circular end root 202, and a gear 203 is formed at an edge of the circular end root 202; in fact, instead of a full gear, the gear 203 is formed only at the edge of the circular arc-shaped end root 202, and there is naturally no tooth at the place where the clamping arm 201 meets.

The bracket 300 comprises a support plate 301, racks 302 are arranged on two sides of the support plate 301, and a sliding block is arranged on the back of the support plate 301; in fact, the electronic terminal such as a mobile phone is placed on the support 300, and the rack 302 will move up and down when the support 300 is extended downward under the gravity pressure of the mobile phone.

A slide rail 103 in which a bracket 300 and a slide block slide is arranged in the middle of the inner side of the bottom shell 101, and pivots 102 around which arc-shaped end roots 202 of the clamping arms 201 rotate are symmetrically arranged on two sides of the slide rail 103;

the gear 203 is meshed with the rack 302 to form a structure that the bracket 300 slides up and down along the slide rail 203 to drive the root part 202 of the arc-shaped end of the clamping arm 201 to rotate around a fulcrum; in practice, the guide rail 103 on which the bracket 300 slides is arranged in the middle of the inner side of the bottom case 101, the guide rail 103 is symmetrically provided with the fulcrums 102, the left and right clamp arms 201 on both sides are fixed on the fulcrums 102 through the center of the arc-shaped end root 202 and can rotate around the fulcrums 102, the support arms 201 drive the clamp blocks 204 to swing, and under the gravity pressure of the electronic terminals such as mobile phones, the bracket 300 slides downwards to drive the right clamp arm 201 to swing reversely, and the right clamp arm 201 swings clockwise, so that the left and right clamp arms 201 synchronously clamp inwards to clamp the electronic terminals such as mobile phones.

In this embodiment, after the electronic terminal such as a mobile phone is removed, or when the shake range in the cab is large, the gravity bracket can still hold the mobile phone because the gravity bracket further includes a locking member 400 for limiting the bracket 300 to slide upwards along the sliding rail 103, and the locking member 400 only limits the bracket 300 to slide upwards along the sliding rail 103, and under the action of gravity, the bracket 300 slides downwards along the sliding rail 103 freely. There are many such retaining members 400, and many can be found by those skilled in the art.

As shown in fig. 2, 3, 4 and 5, the locking member 400 used in this embodiment specifically includes a first spring 401, a second spring 402, a first locking block 403, a second locking block 404, a first helical rack 405, a second helical rack 406, a first inclined surface 407 and a second inclined surface 408.

A first helical rack 405 is disposed on one side wall of a vertically disposed square hole in the middle of the support plate 301, and teeth of the first helical rack have an upward surface and a downward oblique surface.

The second helical rack 406 is arranged on the side of the first locking block 403 and has a downward plane meshed with the first helical rack 405 and teeth with an upward inclined plane; the first helical rack 405 and the second helical rack 406 engage; the elastic force of the first spring 401 causes the second helical rack 406 to move away from the first helical rack 405. Thus, if the second helical rack 406 is stationary, the first helical rack 405 can slide downward but cannot slide upward.

The first inclined surface 407 is provided on the first lock block 403 on the side opposite to the second helical rack 406. The second inclined surface 408 is provided at one side of the second locking block 404.

The second inclined surface (408) presses on the first inclined surface 407; the elastic force of the second spring 402 presses the second inclined surface 408 against the first inclined surface 407, thus forcing the first and

second racks

405 and 406 to engage.

The second locking block 404 extends out of the bottom case 10 in the elastic direction of the second spring 402) to form a button 409. Thus, when the button 409 is pressed inward by an external force, the second inclined surface 408 is separated from the first inclined surface 407 against the elastic force of the second spring 402, and the first pressing piece 403 is no longer pressed downward, so that the first inclined rack 405 and the second inclined rack 406 are no longer engaged under the action of the first spring 401, the locking member 400 is no longer activated, and the bracket 300 is retracted inward toward the housing 100 under the action of the return spring (not shown), and finally returns to the retracted state as shown in fig. 7.

In this embodiment, a guide groove 303 is further provided inside the rack 302 near the support plate 301, a guide rod 106 is provided at a corresponding position on the bottom case 101, and the guide groove 303 is fitted over the guide rod 106 to restrict the left and right swinging of the carriage 300 when the carriage 300 slides up and down along the slide rail 103. The end of the clamping arm 201 is provided with a clamping block 204, the clamping block 204 is provided with a resistance stripe 205, and the outer surface of the surface cover 104 is also provided with a non-slip pad 105 for preventing the electronic equipment which is supported on the surface from sliding, so that the electronic terminals such as mobile phones and the like can be conveniently placed on the non-slip pad.
