Description

A fully automatic clip-on mobile phone holder

technical field

The invention relates to electronic product accessories, in particular to a mobile phone bracket.

Background technique

A clip-type mobile phone holder includes a holder body and a pair of clip blocks.

It is troublesome to manually clamp the mobile phone placed on the support body by a pair of clamping blocks.

The motor drives a pair of clamping blocks, the motor is electrically connected with the photoelectric induction device on the support body, the mobile phone is placed on the support body, the photoelectric induction device senses, and the motor moves. Compared with a pair of manual clamping blocks, the motor drive method is simple, but the photoelectric sensing device can sense any tangible objects near the mobile phone holder, so that the mobile phone holder can perform unexpected actions when it is empty.

The motor drives a pair of clamping blocks. The motor is electrically connected to the contact switch. The action of gravity lowers, the contact switch acts and the motor operates, and a pair of clamping blocks clamp the mobile phone. Although this mobile phone support driven by gravity avoids the disadvantage of unintended operation due to arbitrary induction of the photoelectric induction device, the contact switch is impacted by gravity and has a short service life.

Contents of the invention

The technical problem solved by the invention is to make the mobile phone support controllable and durable.

In order to solve the above technical problems, the present invention provides the following technical solutions: a fully automatic clip-on mobile phone holder, including a pair of clamping blocks arranged on the bracket body, and a drive system for driving the pair of clamping blocks to approach or move away; The heavy support is elastically connected with the bracket body, the heavy support is provided with an induction main part, and the support body is provided with an induction auxiliary part designed to cooperate with the induction main part, and the induction main part or the induction auxiliary part is connected with the drive system electric connection; the induction main part and the induction auxiliary part are located in the inner cavity of the bracket body.

In the above technical solution, the heavy support is located at the bottom of the bracket body and is L-shaped, the vertical part is inserted into the cavity of the bracket body, and the horizontal part is exposed below the bracket body for supporting the mobile phone.

According to the above technical solution, the mobile phone descends along the support body and falls on the heavy support, and the heavy support falls under the gravity of the mobile phone. The main sensing part faces the auxiliary sensing part, and the main sensing part or the auxiliary sensing part operates to make the drive system action, the driving system drives at least one clamping block in the pair of clamping blocks to move to clamp the mobile phone. The elastic connection between the support and the support body makes the mobile phone leave the support, and the support rises and resets. The main sensing part no longer faces the auxiliary sensing part. The main sensing part or the auxiliary sensing part provides a reverse operation signal to the drive system, and a The clamp block is reset due to the reverse movement, and the mobile phone is released.

For the above pair of clamping blocks, one of them is a movable clamping block, and the other is a fixed clamping block, or both clamping blocks are movable clamping blocks, which are uniformly driven by a drive system.

The above-mentioned sensing main part and the sensing auxiliary part are designed and used together, and its function is to provide an action signal to the drive system. The action signal is divided into two types, one is a forward action signal, and the other is a reverse action signal. Wherein, the positive action signal is generated when the main sensing part and the sensing auxiliary part are separated from each other to approach, and the reverse action signal is generated during the process of the main sensing part and the sensing auxiliary part being moved away from each other. The positive action signal causes the drive system to drive the pair of clamping blocks closer together, and the reverse action signal causes the drive system to drive the pair of clamping blocks away.

The above-mentioned inductive main part can be used as a signal sending element and electrically connected with the driving system, or the inductive auxiliary part can be used as a signal sending element and electrically connected with the driving system. Since the main sensing part moves up and down with the support, it is in an active state. Therefore, the preferred sensing auxiliary part is electrically connected to the drive system in this application.

As an option, the main sensing part is a magnet, the auxiliary sensing part is a Hall switch, and the Hall switch is electrically connected to the drive system. The mobile phone falls under the heavy trust, and the magnet drops accordingly. The Hall switch on the front of the magnet acts, and the Hall switch acts to send a positive action signal to the drive system. The drive system drives a pair of clamping blocks to clamp the mobile phone. The mobile phone leaves the heavy trust, the heavy trust rises and resets, the magnet rises away from the Hall switch, the Hall switch sends a reverse action signal to the drive system, and the drive system drives a pair of clamps away to release the mobile phone.

As an option, the induction main part is a magnet, the induction auxiliary part is a reed switch, and the induction auxiliary part is electrically connected with the drive system. The mobile phone is lowered under the heavy support, and the magnet drops accordingly. The reed switch on the front of the magnet moves, and the reed switch moves to send a forward movement signal to the drive system, which drives a pair of clamping blocks to clamp the mobile phone. The mobile phone leaves the heavy trust, and the heavy trust rises to reset, the magnet rises away from the reed switch, the reed switch sends a reverse action signal to the drive system, and the drive system drives a pair of clamps away to release the mobile phone.

The main sensing part is a bar, the auxiliary sensing part is an optocoupler switch, and the auxiliary sensing part is connected with the drive system. The mobile phone is lowered under the heavy trust, and the bar drops accordingly. The bar enters the concave part of the optocoupler switch in a concave shape. The optocoupler switch moves due to the blockage of the bar, and sends a positive action signal to the drive system, and the drive system drives A pair of clamping blocks clamp the mobile phone. The mobile phone leaves the heavy trust, the heavy trust rises and resets, the bar rises away from the concave part of the optocoupler switch, the optocoupler switch sends a reverse action signal to the drive system, and the drive system drives a pair of clamps away to release the mobile phone.

The present invention comprehensively uses the non-contact sensing device and the entrusted device, so that the non-contact sensing device is built in, and the non-contact sensing device is controlled to send different signals to the drive system through the lifting and lowering of the entrusted device, and then controls a pair of clamping blocks Tighten and release the mobile phone to achieve the purpose of accurate automatic control of the mobile phone bracket and prolonging the service life.
