Description

Technical Field

[0001] The invention relates to a sunshade umbrella, in particular to a portable full-automatic sunshade umbrella installed on a car roof. Background Art

[0002] In the summer, the interior of a car exposed to the sun can get very hot, and the interior can become scorching. When the outside temperature is around 36°C, the temperature inside a car parked in the sun for half an hour can soar to around 70°C. Using a car parasol, however, can keep the temperature inside the car around 40°C. In addition to providing sun protection and heat insulation, car parasols also offer protection from rain, wind, sand, dust, bird droppings, damage from fireworks, energy savings, interior protection, and overall health. Currently available car parasols typically utilize a folding frame structure. These structures are bulky when folded, have a high vertical height, provide a large windshield, and are unsightly, making them impractical for driving. Consequently, the parasol must be removed every time the car is driven, and must be temporarily installed whenever the car stops to use it. A general folding car parasol with a skeleton structure weighs about 5 kg, and each time it is removed and installed, it requires a lot of physical strength and time for the car owner. For this reason, although car parasols have many advantages in protecting cars, they are rarely used. The applicant provides a portable fully automatic parasol installed on the roof of a car in Chinese patent application No. 201710900577.1, which can effectively solve the problem that traditional car parasols have a high vertical height, a large windproof area, and are not beautiful, and therefore cannot be driven with the car. However, the structure of patent application No. 201710900577.1 is complex, and no specific technical solution is given on how the baffles of the upper and lower cover plates do not affect the unfolding of the parasol ribs. In actual operation, there is still a disadvantage of not running smoothly. In view of this, the present invention provides a new portable fully automatic parasol installed on the roof of a car. Summary of the Invention

[0003] The technical solution adopted by the present invention to solve the technical problem is: a portable fully automatic sunshade installed on the roof of a car, which includes: an upper cover plate of the sunshade, a lower cover plate, a first cross bar, a second cross bar, two sets of umbrella leaf plane opening and closing mechanisms, two sets of sunshade cloths, a power drive device, a power transmission mechanism, and two sets of roof mounting cross bars; wherein,

[0004] The upper cover of the parasol is provided with baffles around it; the lower cover is provided with two mounting holes on it and two mounting grooves at the lower part, which can form a accommodating space when closed with the upper cover;

[0005] The first crossbar is installed under the upper cover plate and is provided with two large mounting holes and one small mounting hole;

[0006] The second crossbar is installed above the lower cover plate and is provided with two large mounting holes;

[0007] The two sets of umbrella leaf plane opening and closing mechanisms are both installed between the first cross bar and the second cross bar, and are used to support the opening and closing of the parasol in the horizontal and vertical directions, wherein each set of umbrella leaf plane opening and closing mechanisms comprises: an inner sleeve fixedly installed at an upper end of one end of the first cross bar, an outer sleeve sleeved on the inner sleeve and capable of sliding up and down along the inner sleeve, and fixedly installed in the middle at one end of the second cross bar, a lifting spring installed inside the inner sleeve and the outer sleeve, a bottom cover installed at the lower end of the outer sleeve, an I-shaped movable ring sleeved on the upper end of the outer sleeve and capable of freely rotating around the outer sleeve, a shift bolt installed between the upper and lower baffles of the I-shaped movable ring, and used to drive the I-shaped movable ring to rotate, a plurality of umbrella leaves installed between the upper and lower baffles of the I-shaped movable ring, and used to support the sunshade cloth to be expanded and retracted in the horizontal direction, and a traction bolt installed on the outermost umbrella leaf;

[0008] The two sets of sunshade cloths are respectively installed on multiple sets of umbrella leaves of two sets of umbrella leaf plane opening and closing mechanisms for sunshade;

[0009] The power drive device is used to provide driving force for the horizontal folding and vertical closing of the parasol, and includes: a battery, a signal receiving controller, a wireless remote control, a wind sensor switch installed above the upper cover, a drive motor installed inside one of the inner sleeves, a take-up wheel installed on the drive motor shaft, and two limit switches installed inside one of the inner sleeves and above one end of the second crossbar.

[0010] The power transmission mechanism is used to transmit the power of the power drive device, and includes: four wire mechanisms respectively fixedly mounted on the upper ends of the two inner sleeves and the lower ends of the two outer sleeves, and located at the upper and lower ends of the two lifting springs, a lifting eye screw mounted below the middle of the first crossbar, a wire loop mounted on the lifting eye screw, one end of which is mounted on the take-up wheel, which passes through the four wire mechanisms and the small hole at the upper end of the inner sleeve in sequence, and is divided into two by a branch knot, and the rear ends of the parasol closing traction rope are respectively installed on the two traction bolts after passing through the lifting eye screw and the wire loop, and the parasol leaf expansion elastic rope with its two ends respectively mounted on the two traction bolts and passing through the two I-shaped movable rings;

[0011] The two sets of roof mounting cross bars are respectively installed in the roof cross bar mounting grooves of the sunshade lower cover plate, so as to fix the sunshade on the top of the car;

[0012] Furthermore, the wind force sensing switch can sense the wind force and, when the wind force reaches a certain intensity, send a closing signal to the signal receiving controller, so that the parasol starts the closing procedure to protect the parasol;

[0013] Furthermore, the lifting spring is in a compressed state when the parasol is closed, and can provide elastic force for lifting the upper cover of the parasol in the vertical direction;

[0014] Furthermore, when the parasol leaves are unfolded in the horizontal direction, the shift bolt can drive the I-shaped movable ring to rotate half a circle during the process of the outermost leaf rotating a circle;

[0015] Furthermore, the four wire guide mechanisms, each of which is provided with a wire routing hole and is equipped with two wire guide wheels, are used to route the parasol closing traction rope; at the same time, the four wire guide mechanisms cooperate with the parasol closing traction rope to compress and extend the lift spring, and to maintain synchronization between the two sets of umbrella leaf plane opening and closing mechanisms during the parasol opening and closing operation;

[0016] Furthermore, the elastic rope for unfolding the parasol leaves is in a stretched state when the parasol is in a closed state, and can provide elastic force for the horizontal unfolding of the parasol leaves;

[0017] The portable fully automatic parasol installed on the roof of a car can, on the one hand, realize the sunshade function of the parasol by making the sunshade cloth expand and retract in a circular motion in the horizontal direction under the drive of the elastic rope for expanding the umbrella leaves and the parasol closing traction rope through multiple groups of umbrella leaves installed between the upper and lower baffles of the I-shaped movable ring; on the other hand, it can realize the lifting and lowering of the upper cover of the parasol in the vertical direction under the cooperation of the lifting spring, the parasol closing traction rope and the four wire mechanisms through the inner sleeve and the outer sleeve of the two groups of umbrella leaf plane opening and closing mechanisms, thereby eliminating the influence of the edge baffle of the upper cover on the expansion and retraction process of the parasol leaves.

[0018] Furthermore, the umbrella leaf is mounted between the upper and lower baffles of the I-shaped movable ring by bolts, and comprises: a movable support tube, a trapezoidal support plate fixed on the movable support tube, and an umbrella rib fixed on the trapezoidal support plate;

[0019] Furthermore, the umbrella leaves comprise multiple groups, wherein the tails of the three groups of umbrella leaves located above the rear trunk (when the parasol is in the open state) are all equipped with proximity switches, while the middle parts are all provided with arc-shaped connecting mechanisms and micro-electric push rods are all installed below the arc-shaped connecting mechanisms; when the sunshade is in the open state, when the rear trunk is opened, the proximity switch will send an induction signal to the micro-electric push rod to push the rod out, and then the rear sections of the ribs of the three groups of umbrella leaves are folded upwards through the arc-shaped connecting mechanism; when the rear trunk is closed again, the proximity switch will send a non-induction signal to the micro-electric push rod to make the micro-electric push rod move in the opposite direction, and then the rear sections of the ribs of the three groups of umbrella leaves are all folded downwards through the arc-shaped connecting mechanism. The above actions can eliminate the influence of the parasol on the opening and closing of the car trunk when it is in the open state.

[0020] Furthermore, the inner sleeve and outer sleeve of the two sets of umbrella leaf plane opening and closing mechanisms are fixed to the upper cover and the lower cover near the two ends, rather than the center. In this way, sufficient storage space is reserved for the sunshade cloth on the umbrella leaves of the two sets of umbrella leaf plane opening and closing mechanisms to ensure that the upper cover and the lower cover can store all the sunshade cloth inside the cover and minimize the width of the upper cover and the lower cover.

[0021] Compared with the prior art, the present invention has the following advantages: firstly, the present invention replaces the prior art's solution of supporting the sunshade cloth with a separate main and auxiliary ribs by using the umbrella leaves to fix and support the sunshade cloth in the horizontal direction of the sunshade; and secondly, the present invention simplifies the sunshade cloth's vertical movement mechanism by using a lifting spring disposed in the sleeve in the vertical direction of the sunshade, effectively solving the technical problem of the prior art's sunshade umbrella's poor operation during actual opening and closing. Secondly, the present invention provides a specific structure of the upper and lower covers and a specific technical solution for the baffle of the upper cover to prevent the sunshade leaves from unfolding. Thirdly, the present invention provides a portable, fully automatic sunshade mounted on the roof of a car. In the folded state, the sunshade has the advantages of a small size, a low vertical height, a small windshield area, and an aesthetically pleasing appearance. The sunshade is mounted using two sets of roof-mounted crossbars, allowing the sunshade to be securely fixed to the roof of the car. The combination of the above three aspects allows the sunshade to be driven with the car in the folded state without having to remove the sunshade after each use, greatly enhancing the portability of the car sunshade.
