Description

Technical Field

[0001] This invention relates to a sunshade, specifically a portable, fully automatic sunshade that can be installed on the roof of a car. Background Technology

[0002] In summer, cars exposed to the sun become extremely hot inside, with even the interior scorching. When the outside temperature reaches around 36°C, the interior temperature of a car parked in the sun for half an hour can surge to around 70°C. Using a car sunshade can keep the interior temperature around 40°C. Besides sun protection and heat insulation, car sunshades also offer protection against rain, sand, dust, bird droppings, damage from fireworks, energy saving, interior protection, and health benefits. Currently, most car sunshades on the market use a folding frame structure. This type of sunshade is bulky when folded, very tall, has a large wind-blocking area, and is unsightly. Therefore, it cannot be carried while driving, and must be removed every time the car is driven. Furthermore, it must be temporarily installed each time the car is parked and used. Typical folding car sunshades weigh around 5 kg, and each removal and installation requires significant physical effort and time from the driver. Therefore, despite their numerous advantages in protecting vehicles, car sunshades are rarely used. The applicant has provided a portable, fully automatic sunshade mounted on a car roof in Chinese Patent Application No. 202111159077.X, which effectively solves the problems of traditional car sunshades being too tall, having a large wind-blocking area, and being unsightly, thus preventing them from moving with the vehicle. However, Patent Application No. 202111159077.X uses a single-motor operation mode, resulting in some inconsistencies in the horizontal unfolding process. Therefore, this invention provides a new portable, fully automatic sunshade mounted on a car roof. Summary of the Invention

[0003] The technical solution adopted by this invention to solve its technical problem is: a portable fully automatic sunshade installed on the roof of a car, comprising: an upper cover plate, a lower cover plate, a first crossbar, a second crossbar, two sets of umbrella leaf planar opening and closing mechanisms, two sets of sunshade cloths, a vertical motion drive mechanism, a horizontal motion drive mechanism, a drive control device, and two sets of roof-mounted crossbars; wherein,

[0004] The sunshade umbrella has baffles around its upper cover; the lower cover has two mounting holes on its upper part and two mounting grooves at its lower part, which can form an accommodating space when closed with the upper cover.

[0005] The first crossbar is installed below the upper cover plate and has two large mounting holes.

[0006] The second crossbar is installed above the lower cover plate and has two large mounting holes and four small mounting holes.

[0007] The two sets of umbrella blade planar opening and closing mechanisms are both installed between the first and second crossbars to support the opening and closing of the sunshade in the horizontal and vertical directions. Each set of umbrella blade planar opening and closing mechanisms includes: an inner sleeve fixedly installed at one end of the first crossbar; an outer sleeve fitted onto the inner sleeve and slidable up and down along the inner sleeve and fixedly installed in the middle at one end of the second crossbar; an I-shaped movable ring fitted onto the upper end of the outer sleeve and rotatable around the outer sleeve; and upper and lower baffles installed between the I-shaped movable ring to drive the I-shaped movable ring. The components include: a rotating stop bolt; multiple umbrella leaves installed between the upper and lower baffles of the I-shaped movable ring to support the horizontal unfolding and retraction of the sunshade cloth; a traction ear installed on the outermost umbrella leaf with a traction hole; a lifting spring installed inside the inner and outer sleeves to provide lift for the upper cover to rise; a horizontal movement traction gear for the umbrella leaf that is mounted on the outer sleeve and can rotate freely around the outer sleeve; a traction rod with one end fixed to the horizontal movement traction gear for the umbrella leaf and the other end passing through the traction hole on the traction ear; and a bottom cover installed at the lower end of the outer sleeve.

[0008] The two sets of sunshade cloths are respectively installed on multiple umbrella blades of the two sets of umbrella blade plane opening and closing mechanisms for sunshade.

[0009] The vertical motion drive mechanism is used to provide driving force for the vertical closing of the upper cover of the sunshade. It includes: a battery, a No. I drive motor installed inside one of the inner sleeves, a take-up reel installed on the shaft of the No. I drive motor, four wire mechanisms fixedly installed at the upper ends of the two inner sleeves and the lower ends of the two outer sleeves respectively, and located at the upper and lower ends of the two lifting springs, two wire tubes installed on the left and right sides below the first crossbar, an upper cover closing traction rope with one end installed on the take-up reel, passing through the four wire mechanisms, the two wire tubes and the small holes at the upper ends of the two inner sleeves, and the rear end fixed to one wire mechanism, and two switch trigger balls fixed to the upper cover closing traction rope.

[0010] The horizontal motion drive mechanism is used to provide driving force for the horizontal unfolding and retraction of the umbrella blades, and to keep the two outermost umbrella blades of the two sets of umbrella blade planar opening and closing mechanisms synchronized during the unfolding and retraction process. It includes: a Z-shaped fixed bracket installed above the middle of the second crossbar; a No. II drive motor installed above the Z-shaped fixed bracket; a bevel gear I installed on the shaft of the No. II drive motor; two smooth rod bolts and two fisheye bolts installed above the second crossbar; two transmission rods respectively installed on both sides of the Z-shaped fixed bracket and on the fisheye bolts; two bevel gears II respectively installed on one end of the two transmission rods and meshing with the left and right sides of bevel gear I; two bevel gears III respectively installed on the other end of the two transmission rods; two bevel gears IV respectively movably installed on the two smooth rod bolts and meshing with the two bevel gears III; and two spur gears V respectively fixed below the two bevel gears IV and meshing with the two umbrella blade horizontal motion traction gears.

[0011] The drive control device is used to control the opening and closing of the sunshade umbrella, and includes: a signal receiving controller, a wireless remote control, a wind sensor switch installed on the top cover plate, a switching micro switch I installed on the right port of the left guide tube and fixed below the first crossbar, a limit micro switch III installed on the left port of the right guide tube and fixed below the first crossbar, and a switching micro switch II and a limit micro switch IV installed on the top of the second crossbar.

[0012] The switching micro switch I is used to switch the power supply from drive motor I to drive motor II during the opening of the sun umbrella; the switching micro switch II is used to switch the power supply from drive motor II to drive motor I during the closing of the sun umbrella; the limit micro switch III is used to cut off the power supply to drive motor I when the upper cover is lowered to the correct position during the closing of the sun umbrella; the limit micro switch IV is used to cut off the power supply to drive motor II when the umbrella leaves are fully extended in the horizontal direction during the horizontal unfolding of the sun umbrella.

[0013] The two sets of roof-mounted crossbars are respectively installed in the roof crossbar mounting grooves of the sunshade cover plate, so as to fix the sunshade to the top of the car.

[0014] Furthermore, the wind-sensing switch can sense the wind force and send a shutdown signal to the signal receiving controller when the wind force reaches a certain intensity, so that the sun umbrella can start the shutdown procedure to protect the sun umbrella.

[0015] Furthermore, the lifting spring is in a compressed state when the sunshade is closed, which can provide elastic force for the vertical lifting of the sunshade cover.

[0016] Furthermore, the stop bolt, when the umbrella leaf is unfolded in the horizontal direction, can drive the I-shaped movable ring to rotate half a turn during the rotation of the outermost leaf.

[0017] Furthermore, each of the four wire guide mechanisms has a wire routing hole and two wire guide wheels for routing the upper cover plate closing traction rope; at the same time, the cooperation between the four wire guide mechanisms and the upper cover plate closing traction rope can extend or compress the lifting spring, thereby raising or lowering the sunshade upper cover plate.

[0018] Furthermore, the umbrella leaf includes: a rifle-shaped umbrella leaf blade and a half-hinged umbrella leaf support, which is installed between the upper and lower baffles of the I-shaped movable ring by means of the umbrella leaf support and bolts, and can rotate around the bolts; the umbrella leaf blade is integrally processed from glass fiber board and fixedly installed on the umbrella leaf support.

[0019] Furthermore, the umbrella leaf comprises multiple leaves. When the sunshade is in the open state, the three leaves located above the trunk at the rear of the vehicle are each broken into two sections at the middle, and each of the three leaves is equipped with a magnetic locking mechanism at the middle. The magnetic locking mechanism includes a magnetic locking bracket and two permanent magnets. The magnetic locking bracket is fixed to the front section of the broken section of the umbrella leaf. Of the two permanent magnets, one is mounted on the magnetic locking bracket, and the other is mounted on the rear section of the broken section of the umbrella leaf. The rear section of the broken section of the umbrella leaf is movably mounted on the magnetic locking bracket and can rotate around the magnetic locking bracket. The sunshade rotates vertically. When the sunshade is open, as the trunk opens and moves upward to contact the rear section of the three umbrella leaves at the break in the middle, and reaches a certain force, the two permanent magnets of the magnetic locking mechanism will separate under the pushing force, allowing the rear section of the three umbrella leaves at the break in the middle to fold upward. When the trunk closes again, under the action of gravity and the attraction of the two permanent magnets, the magnetic locking mechanism can make the rear section of the three umbrella leaves at the break in the middle fold downward and lock it in place by magnetic force. The above actions can eliminate the influence of the sunshade on the opening and closing of the car trunk when the sunshade is open.

[0020] Furthermore, the inner and outer sleeves of the two sets of umbrella blade planar opening and closing mechanisms are fixed to the sides rather than the center, near the ends of the upper and lower cover plates. This provides sufficient storage space for the sunshade cloth on the umbrella blades of the two sets of umbrella blade planar opening and closing mechanisms, ensuring that the upper and lower cover plates can fully store the sunshade cloth inside the cover plates and minimize the width of the upper and lower cover plates.

[0021] This invention relates to a portable, fully automatic sunshade that can be installed on the roof of a car. On one hand, multiple umbrella leaves installed between the upper and lower baffles of an I-shaped movable ring can be horizontally moved by a traction rod on a gear, causing the sunshade fabric to unfold and retract horizontally in a circular motion under the drive of the horizontal motion drive mechanism, thus achieving the sunshade function. On the other hand, the upper cover can be vertically raised and lowered through the combined action of a vertical motion drive mechanism and a lifting spring, thereby eliminating the influence of the edge baffles of the upper cover on the unfolding and retracting process of the umbrella leaves.

[0022] Compared with the prior art, the beneficial effects of this invention are as follows: Firstly, by adopting a dual-motor control mode to separately control the horizontal movement of the umbrella blades and the vertical movement of the umbrella cover, this invention effectively solves the technical problem of poor operation of the sunshade during actual opening and closing when using a single-motor control mode. Secondly, the umbrella blades of this invention are made of integrated glass fiber board, which improves the strength of the umbrella blades while reducing the weight of the sunshade, effectively solving the problem of processing materials for the umbrella blades. Thirdly, this invention provides a portable fully automatic sunshade that can be installed on the roof of a car. When folded, it has advantages such as small size, low vertical height, small windproof area, and aesthetic appeal. It uses two sets of roof-mounted crossbars to securely fix the sunshade to the car roof. The combination of these three aspects allows the sunshade to move with the car when folded, eliminating the need to remove it after each use, greatly enhancing the portability of the car sunshade.

[0041] The two sets of sunshade cloths (50) are respectively installed on multiple umbrella blades (104) of the two sets of umbrella blade plane opening and closing mechanisms (10) for sunshade;

[0042] The vertical motion drive mechanism (201-206) is used to provide driving force for the vertical closing of the upper cover (601) of the sunshade. It includes: a battery (201), a drive motor (202) installed inside one of the inner sleeves (101), a take-up reel (2021) mounted on the shaft of the drive motor (202), and two lifting springs (101-206) respectively fixedly installed inside the upper ends of the two inner sleeves (101) and the lower ends of the two outer sleeves (102). 5) Four wire mechanisms (203) at the top and bottom ends, two wire tubes (205) installed on the left and right sides below the first crossbar (603), one end of which is installed on the take-up reel (2021), passing through the small holes at the top of the four wire mechanisms (203), the two wire tubes (205) and the two inner sleeves (101) in the middle, and the rear end is fixed to the upper cover plate of one wire mechanism (203) to close the traction rope (204), and two switch touch balls (2041) fixed on the upper cover plate to close the traction rope (204).

[0044] The drive control device (701-707) is used to control the opening and closing of the sunshade, and includes: a signal receiving controller (702), a wireless remote controller (701), a wind sensor switch (703) installed on the top cover plate (601), a switching micro switch I (704) installed on the right port of the left guide tube (205) and fixed below the first crossbar (603), a limit micro switch III (706) installed on the left port of the right guide tube (205) and fixed below the first crossbar (603), a switching micro switch II (705) and a limit micro switch IV (707) installed on the top of the second crossbar (604);

[0045] The switching micro switch I (704) is used to switch the power supply from drive motor I (202) to drive motor II (301) when the vertically moving upper cover plate (601) is raised to its position during the opening of the sun umbrella, thereby starting the horizontal unfolding movement of the sun umbrella blades (104) by the activation of the left-side switch contact ball (2041) on the upper cover plate closing traction rope (204); the switching micro switch II (705) is used to switch the power supply from drive motor I (202) to drive motor II (301) when the horizontally moving umbrella blades (104) are retracted to their position during the closing of the sun umbrella, thereby starting the horizontal unfolding movement of the sun umbrella blades (104) by the activation of the traction rod (1061) on the horizontal movement traction gear (106) of the umbrella blades. The drive motor (301) is switched to drive motor I, thereby starting the descent of the sunshade cover (601) in the vertical direction; the limit micro switch III (706) is used to cut off the power of drive motor I (202) by the activation of the right-side switch contact ball (2041) when the sunshade is closed and the cover (601) has descended to the position; the limit micro switch IV (707) is used to cut off the power of drive motor II (301) by the activation of the traction rod (1061) on the horizontal movement traction gear (106) when the sunshade leaf (104) has unfolded to the position in the horizontal direction.

[0046] Reference Figure 5 , Figure 10 The two sets of roof mounting crossbars (40) are respectively installed in the mounting groove of the sunshade cover plate (602) to fix the sunshade to the top of the car.

[0047] Reference Figure 1 ,According to Figure 10 , Figure 11 Furthermore, the wind-sensing switch (703) can sense the wind force and send a shutdown signal to the signal receiving controller (702) when the wind force reaches a certain intensity, so that the sun umbrella starts the shutdown procedure to protect the sun umbrella.

[0048] Reference Figure 6Furthermore, the lifting spring (105) is in a compressed state when the sunshade is closed, and can provide elastic force for the vertical lifting of the sunshade cover plate (601).

[0049] Reference Figure 2 , Figure 3 , Figure 8 , Figure 9 Furthermore, the stop bolt (1031) can drive the I-shaped movable ring (103) to rotate half a turn during the rotation of the outermost umbrella leaf (104) in the horizontal direction when the umbrella leaf (104) is unfolded.

[0050] Reference Figure 2 , Figure 4 Furthermore, each of the four wire guide mechanisms (203) has a wire hole and two wire guide wheels (2031) for guiding the upper cover plate closing traction rope (204); at the same time, the cooperation between the four wire guide mechanisms (203) and the upper cover plate closing traction rope (204) can extend or compress the lifting spring (105), thereby raising or lowering the sunshade upper cover plate (601);

[0051] Reference Figure 4 Furthermore, the umbrella leaf (104) includes: a rifle-shaped umbrella leaf blade (1041) and a half-hinged umbrella leaf support (1042), which is installed between the upper and lower baffles of the I-shaped movable ring (103) by the umbrella leaf support (1042) and bolts, and can rotate around the bolts; the umbrella leaf blade (1041) is integrally processed from glass fiber board and fixedly installed on the umbrella leaf support (1042);

[0052] Reference Figure 11Furthermore, the umbrella leaf (104) comprises multiple leaves. When the sunshade is in the open state, the three leaves (104) located above the trunk at the rear of the vehicle are each broken into two sections at the middle, and each of the three leaves (104) is provided with a magnetic locking mechanism (1044) at the middle. The magnetic locking mechanism (1044) includes a magnetic locking bracket (1045) and two permanent magnets (1046). The magnetic locking bracket (1045) is fixed to the front section of the broken section of the umbrella leaf. Of the two permanent magnets (1046), one permanent magnet (1046) is installed on the magnetic locking bracket (1045), and the other is installed on the rear section of the broken section of the umbrella leaf. The rear section of the broken section of the umbrella leaf is movably mounted. The system is mounted on a magnetic lock bracket (1045) and can rotate vertically around the magnetic lock bracket (1045). When the sunshade is open, when the trunk opens and moves upward to contact the rear section of the three umbrella leaves at the break in the middle, and reaches a certain force, the two permanent magnets (1046) of the magnetic lock mechanism (1044) will separate under the action of thrust, so that the rear section of the three umbrella leaves at the break in the middle can be folded upward. When the trunk closes again, under the action of gravity and the attraction of the two permanent magnets (1046), the magnetic lock mechanism (1044) can make the rear section of the three umbrella leaves at the break in the middle fold downward and lock it with magnetic force. The above actions can eliminate the influence of the sunshade on the opening and closing of the car trunk when the sunshade is open.

[0053] Reference Figure 8 Furthermore, the inner sleeve (101) and outer sleeve (102) of the two sets of umbrella blade plane opening and closing mechanisms (10) are both located on the side rather than in the center, and are fixed to the upper cover plate (601) and the lower cover plate (602) near both ends. In this way, sufficient storage space is reserved for the sunshade cloth (50) on the umbrella blades (104) of the two sets of umbrella blade plane opening and closing mechanisms (10), so as to ensure that the upper cover plate (601) and the lower cover plate (602) can store the sunshade cloth (50) completely inside the cover plate and minimize the width of the upper cover plate (601) and the lower cover plate (602).

[0054] The closing and opening process of a portable, fully automatic sunshade installed on the roof of a car according to the present invention is as follows:

[0055] Reference Figure 1 , Figure 3 , Figure 6 , Figure 7The opening process of the sun umbrella consists of two steps: first, the top cover (601) of the sun umbrella opens vertically, and then the umbrella leaves (104) unfold horizontally. Specifically, when the sun umbrella is closed, the wireless remote control (701) sends an opening signal to the signal receiving controller (702). The signal receiving controller (702) controls the No. 1 drive motor to reverse according to the signal. The reversal of the No. 1 drive motor causes the take-up reel (2021) to drive the top cover to close, releasing the traction rope (204). Then, through the four wire guide mechanisms (203), the lifting spring (105) is decompressed and extended, thereby causing the inner sleeve (101) and the top cover (601) to open horizontally. The umbrella rises until the left-side switch trigger ball (2041) on the closing traction rope (204) of the upper cover plate touches the switching micro switch I (704), switching the power from drive motor I (202) to drive motor II (301). This stops drive motor I (202) and starts drive motor II (301), stopping the inner sleeve (101) and the upper cover plate (601) from rising. At this point, the vertical lifting movement of the upper cover plate (601) of the sunshade is complete. Next, drive motor II (301) rotates forward, starting the horizontal unfolding movement of the umbrella blades (104). The rotation of drive motor II (301) drives the two umbrella leaf horizontal movement traction gears (106) to rotate clockwise through the horizontal motion drive mechanism, which in turn drives the two traction rods (1061) to rotate. The rotation of the two traction rods (1061) finally drives the two outermost umbrella leaves (104) to rotate clockwise in the horizontal plane through the two traction ears (1043), which in turn drives all umbrella leaves (104) and two I-shaped movable rings (103) to rotate clockwise in the horizontal plane until one traction rod (1061) just contacts the limit micro switch IV (707), cutting off the power to drive motor II (301) and stopping drive motor II (301). At this time, all the umbrella leaves (104) and the sunshade cloth (50) of the sunshade umbrella have been fully unfolded, completing the unfolding movement of the umbrella leaves (104) in the horizontal plane, thus completing the opening process of the sunshade umbrella.

[0056] Reference Figure 1 , Figure 3 , Figure 7 , Figure 6The closing process of the sun umbrella consists of two steps: first, the umbrella leaves (104) fold in the horizontal direction, and then the top cover (601) closes in the vertical direction. Specifically, when the sun umbrella is open, the wireless remote control (701) sends a closing signal to the signal receiver controller (702). The signal receiver controller (702) controls the No. II drive motor (301) to reverse according to the signal. The rotation of the No. II drive motor (301) drives the two umbrella leaf horizontal movement traction gears (106) to rotate counterclockwise through the horizontal movement drive mechanism, which in turn drives the two traction rods (1061) to rotate counterclockwise. The rotation of the two traction rods (1061) ultimately drives the two outermost umbrella leaves (104) to rotate counterclockwise in the horizontal direction through the two traction ears (1043), thereby driving all umbrella leaves (104) and the two I-shaped... The movable ring (103) rotates counterclockwise in the horizontal direction until a traction rod (1061) just touches the switching micro switch II (705), switching the power from drive motor II (301) to drive motor I (202), causing drive motor II (301) to stop and drive motor I (202) to start. At this time, all the umbrella leaves (104) and sunshade cloth (50) of the sunshade are completely stored above the lower cover plate (602), thus completing the retraction movement of the umbrella leaves (104) in the horizontal direction. Next, drive motor I (202) starts to rotate clockwise, starting the descent movement of the upper cover plate (601) of the sunshade in the vertical direction. The rotation of drive motor I (202) causes the take-up reel (2021) to drive the upper cover closing traction rope (204) to take in the line. The take-in of the upper cover closing traction rope (204) compresses the lifting spring (105) through the four wire mechanisms (203), thereby causing the inner sleeve (101) and the upper cover (601) to descend until the right-side switch trigger ball (2041) installed on the upper cover closing traction rope (204) touches the limit micro switch III (706), cutting off the power to drive motor I (202) and stopping drive motor I (202). At this time, the upper cover (601) of the sun umbrella is exactly above the lower cover (602), thus completing the vertical closing movement of the upper cover (601) of the sun umbrella, and thus completing the closing process of the sun umbrella.
