Detailed Description

In order to make the technical problems, technical solutions and advantageous effects to be solved by the present application clearer, the present application is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.

It will be understood that when an element is referred to as being "secured to" or "disposed on" another element, it can be directly on the other element or be indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly or indirectly connected to the other element.

It will be understood that the terms "length," "width," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," and the like, refer to an orientation or positional relationship illustrated in the drawings for convenience in describing the present application and to simplify description, and do not indicate or imply that the referenced device or element must have a particular orientation, be constructed and operated in a particular orientation, and thus should not be construed as limiting the present application.

Furthermore, the terms "first", "second" and "first" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the present application, "a plurality" means two or more unless specifically limited otherwise.

The utility model provides a manual-automatic sun-shading umbrella stand, refers to fig. 1 to fig. 3, include bracing piece 1, rib 2 and install first branch 3 and second branch 4 that are used for expandeing and contract rib 2 between bracing piece 1 and rib 2, first branch 3 with second branch 4 is articulated mutually, second branch 4 keeps away from that the one end of rib 2 articulates there is adjusting box 5, adjusting box 5 sliding connection is in bracing piece 1, bracing piece 1 is equipped with rack 11 along the length direction of bracing piece 1, adjusting box 5 internal rotation be connected with rack 11 meshed gear 51 and install the drive division 6 that is used for drive and positioning gear 51.

When the sunshade umbrella is unfolded, a user starts the driving part 6 to drive the gear 51 to move upwards along the rack 11, so that an included angle between the second support rod 4 hinged with the adjusting box 5 and the first support rod 3 is driven to be reduced, the umbrella ribs 2 are further opened, and the purpose of automatically unfolding the sunshade umbrella is achieved;

when the sunshade umbrella is contracted, a user starts the driving part 6 to drive the gear 51 to move downwards along the rack 11, so that an included angle between the second support rod 4 and the first support rod 3 which are hinged with the adjusting box 5 is increased, the umbrella ribs 2 are further contracted, and the purpose of automatically contracting the sunshade umbrella is achieved.

Specifically, the driving part 6 is a worm gear speed reduction motor. The worm gear and worm gear speed reducing motor has a self-locking function and can achieve the purpose of positioning the sunshade to keep opening.

In the present embodiment, a control circuit board 52 and a storage battery 53 are further included, which are mounted inside the adjustment box 5, and the storage battery 53 and the driving portion 6 are electrically connected to the control circuit board 52, respectively.

Specifically, differential mechanism 7 is installed to gear 51 and regulation box 5 inner wall, differential mechanism 7 is kept away from gear 51's one end and is installed handle 8, handle 8 is located regulation box 5 outside. The setting of this structure, when drive division 6 meets accident or the outage can not start, user's accessible manual mode and then drive, and then accomplish the shrink and the expansion of sun shade, have the fault-tolerant rate height, the advantage that the practicality is strong.

Specifically, a plurality of pulleys 9 which are matched with the support rod 1 in a rolling manner are rotatably arranged in the adjusting box 5. The pulley 9 further reduces the frictional resistance between the adjusting box 5 and the supporting rod 1, and is beneficial to improving the adjusting fluency.

Specifically, the pulley 9 is installed opposite to the rack 11 on the support rod 1. Thus, the stress balance is facilitated, and the structural stability is higher.

In this embodiment, a hydraulic cylinder (not shown in the figure) can be hinged between the first supporting rod 3 and the second supporting rod 4, so as to reduce the power of the driving part 6 and improve the structural stability; a remote control device (not shown in the figure) connected with the driving part 6 can be further arranged, so that the folding and unfolding of a plurality of sunshade umbrellas can be conveniently and uniformly controlled, and the sunshade umbrellas are applied to scenes such as high-end hotels, coffee houses and the like; and a solar panel (not shown in the figure) electrically connected with the storage battery 53 can be arranged, so that the energy is saved and the environment is protected.
