Sunshade opening and closing mechanism and portable full-automatic automobile sunshade using same

Abstract

A sunshade opening and closing mechanism comprises a multi-stage casing, a power driving device, a step-by-step driving ring, a driven traction ring, a fixing ring, a main moving ring, a sub moving ring and multiple groups of multi-stage X-shaped telescopic brackets, wherein the multi-stage casing consists of multiple casings; the power driving device consists of one driving motor and multiple bevel gears; the step-by-step driving ring, the driven traction ring, the fixing ring and the main moving ring are correspondingly mounted on an internal casing of the multi-stage casing from top to bottom; the sub moving ring is mounted on an external casing of the multi-stage casing; and the multiple groups of multi-stage X-shaped telescopic brackets are mounted between the main moving ring and the sub moving ring. According to the sunshade opening and closing mechanism, a defect that a traditional sunshade opening and closing mechanism cannot be unfolded and folded in some comparatively narrower areas because the traditional sunshade opening and closing mechanism must have an enough extending space when being unfolded and folded is overcome; and the portability of an automobile sunshade in use is greatly enhanced.

Description

technical field [0001] The invention relates to a sunshade opening and closing mechanism, in particular to a portable automatic sunshade opening and closing mechanism installed on the roof of a car and a car sunshade using the mechanism. Background technique [0002] In summer, the temperature inside the car exposed to the sun is very high, and the interior is also scorching hot. When the outside temperature reaches about 36°C, the temperature inside the car will suddenly rise to 70°C if the car is parked in the sun for half an hour. The temperature inside the car can be kept at around 40°C by using a car sunshade. In addition to the function of sun protection and heat insulation, car parasols also have the functions of preventing rain, wind and sand, dust and bird droppings, preventing damage from fireworks and firecrackers, energy saving, interior protection and health protection. The car parasols seen on the market generally adopt a folding skeleton structure. The car pa...

AI Technical Summary

Problems solved by technology

The car parasols seen on the market generally adopt a folding skeleton structure. The car parasols with this structure have a large volume when folded, a high vertical height, a large windshield area, and are not beautiful, so they cannot be driven with the car. So every time you drive, you need to remove the car sunshade, and at the same time, you must temporarily install it every time you stop and use the car sunshade

The weight of the general folding frame structure car sunshade is about 5Kg. Every time it is unloaded and installed, it needs to consume a lot of physical strength and time of the car owner. Because of this, although the car sunshade has many advantages for car protection, it is very rarely used

The applicant provided a parasol rib plane unfolding and folding mechanism in Chinese patent application number 201810779128.0, which can effectively solve the problem that the traditional car sunshade has a high vertical height, a large windshield area, and is not beautiful, so it cannot be driven with the car. question

However, the patent application number 201810779128.0 does not provide the specific technical scheme of how to open the sunshade umbrella in the vertical direction and how to realize the half-circle rotation of the main movable ring in the horizontal plane direction, while the umbrella surface is unfolded for a week. In view of this, the present invention provides a Sunshade opening and closing mechanism and a portable fully automatic car sunshade using the mechanism
