Parallelogram connecting rod type automatic clamping bracket

Abstract

The invention discloses a parallelogram connecting rod type automatic clamping bracket. The parallelogram connecting rod type automatic clamping bracket comprises a back side base, a bottom support arm, a left side clamping arm, a right side clamping arm and a reset elastic element, wherein both the left side clamping arm and the right side clamping arm comprise clamping parts, first connecting rods and second connecting rods; a first rotating support point and a second rotating support point are arranged one above the other at an interval on the bottom support arm specific to the left side clamping arm and the right side clamping arm; a third rotating support point and a fourth rotating support point are arranged one above the other on the clamping part; inner and outer ends of a first connecting rod are pivoted to the first rotating support point and the third rotating support point respectively; inner and outer ends of a second connecting rod are pivoted to the second rotating support point and the fourth rotating support point respectively; and the first, second, fourth and third rotating support points are connected in sequence to form a parallelogram structure. The bottom support arm is pressed downwards under the gravity of a mobile phone, and the mobile phone is clamped automatically through inward obliquely-upward displacement of the clamping part by means of the deformation principle of a parallelogram, so that angular change of a clamping surface on the clamping part is prevented, and good contact clamping of the mobile phone is ensured.

Description

technical field [0001] The invention relates to the technical field of brackets for mobile devices such as mobile phones, in particular to a parallelogram connecting rod type automatic clamping bracket. Background technique [0002] At present, with the popularization of mobile devices such as mobile phones, mobile phone holders have also been widely used. Most of the existing mobile phone holders need to be clamped and fixed manually, and a few are designed for automatic clamping, which generally detects whether the mobile phone is placed through a pressure sensor sensor, and a single-chip microcomputer or a microcontroller controls the electric motor according to the detected rotation state of the mobile phone. Driven to realize automatic clamping, it has the disadvantages of complex structure, high production cost, power consumption, easy failure, poor stability in use, etc., and is not suitable for popularization and application. There are also some that directly use th...

Problems solved by technology

Most of the existing mobile phone holders need to be clamped and fixed manually, and a few are designed for automatic clamping, which generally detects whether the mobile phone is placed through a pressure sensor sensor, and a single-chip microcomputer or a microcontroller controls the electric motor according to the detected rotation state of the mobile phone. Drive to realize automatic clamping, which has disadvantages such as complex structure, high production cost, power consumption, easy failure, and poor stability in use, so it is not suitable for popularization and application

There are also some that directly use the gravity of mobile phones and other products to link the rotation of the clamping arms on both sides to realize the clamping of placed mobile phones and other products, which solves the problem of power consumption, but there are linkage stability and contact clips. Insufficient such as poor holding effect
