一种电动升降可移动伞座An electric lift movable umbrella seat 技术领域technical field
本发明涉及户外遮阳伞技术领域，涉及一种遮阳伞的伞座，尤其涉及一种电动升降可移动伞座。The invention relates to the technical field of outdoor sunshades, relates to an umbrella seat of a sunshade, and in particular relates to an electric liftable movable umbrella seat.
背景技术Background technique
遮阳伞作为一种户外休闲用具，广泛用于广场、海滩、公园及庭院等休闲场所，为人们提供了舒适的乘凉空间。而由于这种大型伞具撑开时伞面的面积较大，受风吹等影响下，为了保证伞具的稳定性和平衡性，通常会将伞具的支撑管固定在伞座上，而为了防止遮阳伞受风吹时出现倾翻的现象，目前的伞具需要配备足够重量的伞座。As an outdoor leisure tool, parasols are widely used in leisure places such as squares, beaches, parks and courtyards, providing people with a comfortable cool space. Due to the large area of the umbrella surface when the large umbrella is opened, under the influence of wind blowing, etc., in order to ensure the stability and balance of the umbrella, the support tube of the umbrella is usually fixed on the umbrella seat, and In order to prevent the parasol from tipping over when it is blown by the wind, the current umbrella needs to be equipped with an umbrella seat of sufficient weight.
为了保持与伞盖的平衡，伞座的体积均较大或重量较重。当伞座具有足够重量并且伞座的着地面积较大的情况下，移动伞座时会非常的不方便，为了解决上述技术问题，目前市面上出现了带有轮子的伞座，使伞座的移动更加地方便、轻松，当不需要轮子时，将轮子隐藏在伞座的底部，当伞座地面着地；需要轮子时，用手拨动轮子，轮子与地面接触而能自由滚动，但是在将轮子隐藏和拨出时，需要人力操作，非常费力。In order to maintain the balance with the umbrella cover, the umbrella bases are all larger or heavier in weight. When the umbrella seat has enough weight and the landing area of the umbrella seat is large, it will be very inconvenient to move the umbrella seat. In order to solve the above technical problems, there are umbrella seats with wheels on the market. It is more convenient and easy to move. When the wheel is not needed, hide the wheel at the bottom of the umbrella seat, and when the umbrella seat is on the ground; when the wheel is needed, turn the wheel by hand, the wheel contacts the ground and can roll freely. When the wheels are hidden and pulled out, manual operation is required, which is very laborious.
经查，现有专利号为CN201920857601.2的中国实用新型专利《一种可移动伞座》，包括底座、设置在底座的底部的轮架和脚轮，脚轮至少有三个，并间隔布置在所述轮架上；且至少部分位于所述轮架的底部；还包括气囊和始终具有使所述轮架和脚轮相对底座向上运动趋势的弹性件，该气囊位于所述轮架和底座所围合形成的空间内，且在所述气囊充气并处于膨胀状态下，所述脚轮至少部分露出所述底座的底部；在所述气囊排气处于收缩状态下，所述脚轮能藏于所述底座内。该伞座需使用者自行提供充气工具，如气泵、打气筒等对其内部的气囊进行充气放气，使用不够灵活方便；且当使用者对气囊过多的充气可能会导致气囊的寿命缩短甚至破损。After investigation, the existing Chinese utility model patent No. CN201920857601.2, "A Movable Umbrella Base", includes a base, a wheel frame and casters arranged at the bottom of the base. There are at least three casters, and they are arranged at intervals in the and at least partially located at the bottom of the wheel frame; further comprising an air bag and an elastic member that always has a tendency to make the wheel frame and the caster move upward relative to the base, the air bag is formed by being surrounded by the wheel frame and the base In the space where the airbag is inflated and in an inflated state, the caster at least partially exposes the bottom of the base; when the airbag is deflated and in a retracted state, the caster can be hidden in the base. The umbrella stand requires the user to provide inflation tools, such as air pump, air pump, etc. to inflate and deflate the airbag inside, which is not flexible and convenient to use; and when the user inflates the airbag too much, the life of the airbag may be shortened or even shortened. damaged.
