Description

Technical Field

[0001] This application relates to the field of vehicle cover technology, and in particular to a vehicle cover that can open and close automatically. Background Technology

[0002] With the increasing prevalence of automobiles in daily life, the need for environmental protection and sun insulation for vehicles parked outdoors for extended periods is becoming increasingly prominent. Especially in hot weather, exposure to direct sunlight causes a rapid rise in interior temperature, accelerating the aging of interior components and electronic devices, and severely impacting the comfort of the driver and passengers. Traditional protective car covers often rely on manual application and folding by the owner, a cumbersome, time-consuming, and laborious process, especially in inclement weather. Therefore, developing an automatically opening and closing car cover solution is particularly necessary.

[0003] To meet the demand for automated protection, some car covers with automatic retractable functions have emerged in the industry. However, existing car covers with automatic retractable functions have some drawbacks. For example, their structures are relatively complex, especially the structures used to implement the retractable mechanism. Some car covers with automatic retractable functions use rigid folding brackets to achieve the retraction and extension of the cover. These products have numerous components such as rigid telescopic rods, hinges, pulleys, and pull ropes, resulting in complex connections. Furthermore, they are relatively heavy, which greatly increases the mechanical load during lifting and retraction, as well as the load on the vehicle. This also leads to serious wear and tear issues and is prone to problems such as pull ropes getting tangled in the mechanical structure, mechanical jamming, and tearing of the canopy. Summary of the Invention

[0004] One advantage of this application is that it provides an automatically opening and closing vehicle cover, wherein the structure of the automatically opening and closing vehicle cover is relatively lightweight and simplified, which can not only significantly reduce the physical weight and driving energy consumption of the entire unfolding frame, but also greatly reduce the risk of mechanical stress tearing and jamming during the stretching process, improve the smoothness of automatic closure and the overall reliability of the vehicle cover, and extend the life of the vehicle cover.

A power supply component is configured to supply power to the first drive device and the air pump to enable their operation; The automatically opening and closing vehicle cover switches between an unfolded state and a retracted state. When the automatically opening and closing vehicle cover is in the unfolded state, the inflation tube expands and unfolds, thereby causing the cover to unfold. When the automatically opening and closing vehicle cover is in the retracted state, the inflation tube contracts, the first driving device drives the first rotating plate to rotate, thereby causing the cover and the inflation tube to wind up around the winding assembly.

Detailed Implementation

[0027] The following description, in conjunction with the accompanying drawings of the embodiments of this application, will clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative work are within the protection scope of this application.

[0028] In this application, the terms "first," "second," etc., are used to distinguish different objects rather than to describe a specific order. Furthermore, the terms "comprising," "owning," and any variations thereof are intended to cover non-exclusive inclusion.

[0029] While terms such as “front,” “back,” “left,” “right,” “up,” and “down” may be used in describing various exemplary features and elements herein, these terms are used for convenience, for example, based on the example orientations shown in the figures and / or orientations in typical use. Nothing in this specification should be construed as requiring a particular three-dimensional or spatial orientation of the structure to fall within the scope of the claims.

[0030] It should be noted that when one element is fixed to another element, it includes fixing the element directly to the other element, or fixing the element to the other element through at least one intermediate element. When one element is connected to another element, it includes connecting the element directly to the other element, or connecting the element to the other element through at least one intermediate element.

[0031] As mentioned earlier, to meet the demand for automated protection, some car covers with automatic retractable functions have emerged in the industry. However, existing car covers with automatic retractable functions have some drawbacks. For example, their structures are relatively complex, especially the structures used to achieve the retractable function. Some car covers with automatic retractable functions use rigid folding brackets to achieve the retraction and extension of the car cover. These products have numerous components such as rigid telescopic rods, hinges, pulleys, and pull ropes, resulting in complex connections. Furthermore, they are relatively heavy, which greatly increases the mechanical load during lifting and retraction, as well as the load on the vehicle. This also leads to serious wear and tear risks and is prone to problems such as pull ropes getting tangled in the mechanical structure, mechanical jamming, and tearing of the canopy.

[0032] Based on this, this application aims to provide a lightweight, highly reliable, and automatically opening and closing vehicle cover system. To this end, this application proposes a technical concept: utilizing a flexible and efficient pneumatic energy-charging structure to achieve smooth unfolding of the vehicle cover. Specifically, this application designs a rollable assembly that unfolds and retracts pneumatically. When unfolded, the rollable assembly provides sunshade for the vehicle body; when retracted, the rollable assembly shrinks in size.

[0033] Accordingly, as shown in the accompanying drawings of this application specification. Figures 1 to 10 As shown, this application designs an automatically opening and closing vehicle cover, suitable for installation on a vehicle body, to provide sunshade and wind and rain protection for the vehicle. The automatically opening and closing vehicle cover includes a base 40, a first rotating plate 50, a rollable component 20, a first driving device 70, an air pump 30, a positioning component 100, and a power supply component 400.

[0034] The first rotating plate 50 is rotatably mounted on the base 40. The retractable assembly 20 includes a winding assembly 21, a plurality of inflation tubes 22 mounted on the winding assembly 21, and a cover 23 connected between the plurality of inflation tubes 22. The winding assembly 21 is fixedly mounted on the first rotating plate 50, such that the retractable assembly 20 rotates together with the rotation of the first rotating plate 50. The first driving device 70 is tractably connected to the first rotating plate 50 and configured to drive the first rotating plate 50 to rotate. The power supply assembly 400 is configured to supply power to the first driving device 70 and the air pump 30 to enable their operation. The air pump 30 is connected to the inflation tubes 22 and is configured to inflate or deflate the inflation tubes 22. The positioning assembly 100 is configured to trigger a command to stop driving the first rotating plate 50 to rotate when it detects that the first rotating plate 50 has reached a preset position, thereby causing the first rotating plate 50 to stop rotating. The automatically opening and closing vehicle cover switches between an unfolded state S1 and a retracted state S2. When the automatically opening and closing vehicle cover is in the unfolded state S1, the inflation tube 22 expands and unfolds, thereby causing the cover body 23 to unfold; when the automatically opening and closing vehicle cover is in the retracted state S2, the inflation tube 22 retracts, the first driving device 70 drives the first rotating plate 50 to rotate, thereby causing the cover body 23 and the inflation tube 22 to wind up around the winding assembly 21.

[0035] Specifically, the base 40 provides a stable platform suitable for mounting the automatically opening and closing vehicle cover onto the vehicle body, and also provides a mounting carrier for multiple components of the automatically opening and closing vehicle cover. Accordingly, when the automatically opening and closing vehicle cover is mounted on the vehicle body, the lower surface of the base 40 is in contact with the vehicle body.

[0036] In one embodiment of this application, when the automatically opening and closing car cover is in the unfolded state S1, the lower end of the cover body 23 is flush with the lower surface of the base 40, so that when the automatically opening and closing car cover is in the unfolded state S1, the lower end of the cover body 23 is close to the car body, and the air in the space between the rollable component 20, the flying saucer 10 and the car body is a static air layer, which can better insulate heat.

[0037] In one embodiment of this application, when the automatically opening and closing vehicle cover is in the closed state S2, the lower end of the saucer disc 10 is in contact with the cover body 23, and the cover body 23 extends outward from below the saucer disc 10 relative to the saucer disc 10 in at least a portion.

[0038] It is worth mentioning that the automatically opening and closing car cover rotatably mounts the rollable component 20 onto the rotatable first rotating plate 50. Before the inflation tube 22 and the cover 23 are unfolded, the rollable component 20 is unfolded by rotation to facilitate further unfolding.

[0039] The winding assembly 21 includes a winding body 2110. The winding body 2110 is used to provide a winding for the cover 23. The specific shape of the winding body 2110 is set according to requirements.

[0040] In one example of this application, the winding body 2110 is generally cylindrical, having a columnar structure 2111 with a hollow central region 21102 that allows other components to pass through.

[0041] In another example of this application, the winding body 2110 is generally annular, having a ring structure 2112. In one embodiment of this application, the winding body 2110 is an inflatable cavity with an air collection chamber 21101. The winding body 2110 extends vertically. In the embodiment where the winding body 2110 has an air collection chamber 21101, the air pump 30 is connected to the air collection chamber 21101, and further connected to the inflation pipe 22 through the air collection chamber 21101.

[0042] In one example of this application, the columnar structure 2111 has an air collecting chamber 21101, which is a cylindrical air collecting chamber. The air pump 30 is connected to the cylindrical air collecting chamber, and then connected to the inflation pipe 22 through the cylindrical air collecting chamber, enabling it to inflate or de-inflate the air collecting chamber and the inflation pipe 22.

[0043] In another example of this application, the annular structure 2112 has an air collecting chamber 21101, which is an annular air collecting chamber. The air pump 30 is connected to the annular air collecting chamber, and then connected to the inflation pipe 22 through the annular air collecting chamber, enabling it to inflate or de-inflate the air collecting chamber and the inflation pipe 22.

[0044] When the winding body 2110 has a gas collecting cavity 21101, the winding body 2110 can be a fully rigid gas collecting cavity. For example, all side walls, top walls, and bottom walls of the winding body 2110 are made of rigid materials to provide sufficient support and stability. Accordingly, during the process of evacuating the winding body 2110, the winding body 2110 does not shrink significantly and its shape remains essentially unchanged.

[0045] The winding body 2110 may also be made of at least part of a flexible material. In this way, during the process of evacuating the winding body 2110, the winding body 2110 will shrink to a certain extent, making the overall volume of the retractable component 20 smaller, and ensuring that the retractable component 20 can be fully housed in the flying saucer disk 10.

[0046] In one example of this application, the winding body 2110 has the annular structure 2112, which is made of a flexible material. The winding assembly 21 further includes at least one rigid strip 212 disposed on the outer periphery of the annular structure 2112; the at least one rigid strip 212 is located above the inflation tube 22.

[0047] In another example of this application, the winding assembly 21 further includes a rigid retaining ring 213 sleeved on the outer periphery of the annular structure 2112 and driven synchronously with the annular structure 2112; the rigid retaining ring 213 is installed on the outside of the rigid strip 212. The rigid retaining ring 213 has a through hole 2131 corresponding to the inflation tube 22 and suitable for the inflation tube 22 to pass through. The inflation tube 22 extends outward from the through hole 2131. This arrangement ensures that the section of the air bladder structure on the inflation tube 22 located within the outer surface of the rigid retaining ring 213 is rigidly protected by the rigid retaining ring 213. No matter how much force is applied outside the rigid retaining ring 213, the force is mainly transmitted to the outer surface of the rigid retaining ring 213 and cannot press down on the root of the air bladder in the inflation tube 22 located within the outer surface of the rigid retaining ring 213, i.e., the end connected to the winding body 2110. This reduces the stress on the root of the air bladder in the inflation tube 22, which is prone to stress concentration, thereby reducing the risk of rupture at that location.

[0048] The inflation tubes 22 extend radially outward from the winding body 2110. Multiple inflation tubes 22 are evenly arranged and / or symmetrically distributed circumferentially along the winding body 2110. In one example of this application, the circumferential distance between any two adjacent inflation tubes 22 is equal. In another example of this application, at least two inflation tubes 22 are symmetrical about the longitudinal central axis L1 of the winding body 2110. The longitudinal direction of this application is consistent with the vertical direction, the up-down relative direction, and the height direction of the automatically opening and closing vehicle cover. In this application, the side of the automatically opening and closing vehicle cover closest to the vehicle body when installed on the vehicle body is considered "down," and the side furthest from the vehicle body and opposite to its direction of gravity is considered "up." In one example of this application, when the inflation tubes 22 are unfolded, they extend obliquely downward outward from the winding body 2110. Each inflation tube 22 is strip-shaped, resembling the frame of an umbrella. The inflation tubes 22 form a retractable airbag frame.

[0049] In one example of this application, the outer surface of the cover 23 is coated with a highly reflective material to improve the sunshade effect of the automatically opening and closing vehicle cover.

[0050] The cover 23 includes a cover body 231 and at least one connecting element for connecting the inflation tubes 22. The cover body 231 may be a single rollable fabric covering the plurality of inflation tubes 22, or it may be a combined rollable fabric composed of multiple sunshade fabrics connected together.

[0051] In one example of this application, at least one connecting element for connecting the inflation tube 22 includes at least one sleeve 232 connected to the cover body 231. For example, at least one sleeve 232 is provided at an upper end 2311 and a lower end 2312 of the cover body 231, respectively; the inflation tube 22 passes through the sleeve 232.

[0052] In one embodiment of this application, the cover 23 is at least partially fixed to the outer periphery of the winding assembly 21 by connecting components (e.g., Velcro, adhesive, plug-in elements) to improve the structural and positional stability of the cover 23 during the state switching process of the automatically opening and closing vehicle cover.

[0053] In one example of this application, the cover 23 extends outward around the winding assembly 21, with its upper end 2311 passing through the outer periphery of the winding assembly 21 via Velcro.

[0054] In another example of this application, the upper end 2311 of the cover 23 is connected to a plurality of rigid rods, and the winding body 2110 of the winding assembly 21 has a plurality of grooves corresponding to the rigid rods, and the plurality of rigid rods are respectively inserted into the plurality of grooves of the winding body 2110.

[0055] In yet another example of this application, the upper end 2311 of the cover 23 is directly bonded to the winding body 2110.

[0056] The first drive device 70 may be a motor or other device that can provide rotational motion.

[0057] The power supply assembly includes a first power supply device 80 and a second power supply device 90. The first power supply device 80 is configured to supply electrical energy to the first drive unit 70 and remain relatively stationary with respect to the first drive unit 70. It can be implemented as a battery mounted on the base 40 or a connected power battery or starting battery of the vehicle itself. The second power supply device 90 is configured to supply electrical energy to the air pump 30 and remain relatively stationary with respect to the air pump 30. It can be implemented as a battery located inside the automatically opening and closing hood or a connected power battery or starting battery of the vehicle itself.

[0058] The specific structure of the positioning component 100 is not limited to that described in this application. In one example of this application, the positioning component 100 includes a detection hole 110, a photoelectric switch 120, a light-shielding rod 130, a spring 140, and a ball head 150; the detection hole 110 is disposed on the base 40; the photoelectric switch 120 is configured to detect whether the detection hole 110 is blocked; the light-shielding rod 130 is mounted on the first rotating plate 50 and extends toward the base 40; the spring 140 is sleeved on the light-shielding rod 130, and the upper end of the spring 140 is limited. Located on the light-shielding rod 130, the lower end of the spring 140 is connected to the ball head 150; the ball head 150 is located below the light-shielding rod 130; the light-shielding rod 130, the spring 140 and the ball head 150 are driven to rotate by the first rotating plate 50; when the first rotating plate 50 rotates to the point where the ball head 150, which rotates with it, enters the detection hole 110, the photoelectric switch 120 recognizes that the detection hole 110 is blocked, and thus recognizes that the first rotating plate 50 has reached a preset position.

[0059] In another example of this application, the positioning component 100 includes an infrared switch 160 and a light-shielding block 170; the infrared switch 160 is configured to emit infrared light and identify whether the infrared light is blocked; the light-shielding block 170 is disposed on the first rotating plate 50 and is driven to rotate by the first rotating plate 50; when the first rotating plate 50 rotates to the point where the light-shielding block 170 blocks the infrared light, the infrared switch 160 identifies that the infrared light is blocked, and thus identifies that the first rotating plate 50 has reached a preset position.

[0060] In one embodiment of this application, the automatically opening and closing vehicle cover further includes a second rotating plate 60; the second rotating plate 60 is located above the first rotating plate 50 and spaced apart from the first rotating plate. The second rotating plate 60 is disposed on the winding body 2110, or on the rigid strip 212 and / or rigid limiting ring 213 on the outer side of the winding assembly 21.

[0061] In one example of this application, the winding body 2110 has the cylindrical structure; the second rotating plate 60 is disposed on the top of the cylindrical structure 2111.

[0062] In one embodiment of this application, the automatically opening and closing vehicle cover further includes a saucer disc 10. The saucer disc 10 has an internal space 101; the rollable assembly 20 is located below the saucer disc 10; the winding assembly 21 is housed within the internal space 101. When the automatically opening and closing vehicle cover is in the unfolded state S1, at least a portion of the inflation tube 22 and at least a portion of the cover body 23 extend beyond the internal space 101; when the automatically opening and closing vehicle cover is in the closed state S2, the inflation tube 22 and the cover body 23 are completely enclosed within the internal space 101.

[0063] Specifically, the flying saucer disc 10 is arc-shaped; more specifically, the cross-section of the flying saucer disc 10 parallel to the vertical plane is arc-shaped, forming an arc-shaped cover.

[0064] It is worth mentioning that this application uses an airbag structure to realize the opening and closing of the car cover, which can reduce the overall weight of the automatically opening and closing car cover, achieving lightweighting. At the same time, it is necessary to ensure the overall stability of the automatically opening and closing car cover to prevent deformation or displacement of the car cover under conditions such as strong winds and heavy rain. Specifically, the stability of the automatically opening and closing car cover can be improved by reducing wind resistance. In one embodiment of this application, during the process of the automatically opening and closing car cover switching from the unfolded state S1 to the retracted state S2, after the inflation tube 22 retracts and the cover body 23 rolls up, the flying saucer disc 10 descends, which can reduce wind resistance to a certain extent.

[0065] Preferably, after the inflation tube 22 retracts and the cover 23 rolls up, the flying saucer disc 10 descends to be flush with the vehicle body. Thus, even when the cover 23, located below the lower end of the flying saucer disc 10, rolls up, the air in the space between the flying saucer disc 10 and the vehicle body remains a still air layer, providing good heat insulation. Correspondingly, when the automatically opening and closing vehicle cover is in the closed state S2, the lower end of the flying saucer disc 10 is flush with the lower surface of the base 40.

[0066] Accordingly, in one embodiment of this application, the automatically opening and closing vehicle cover further includes a liftable component 200 connected to the flying saucer disc 10 and configured to drive the flying saucer disc 10 to rise and fall; when the automatically opening and closing vehicle cover is in the unfolded state S1, the flying saucer disc 10 is higher than when the automatically opening and closing vehicle cover is in the retracted state S2.

[0067] The specific structure of the liftable assembly 200 is not limited to this application. In one example of this application, the liftable assembly 200 includes a guide seat 210, a support rod 220, and a second drive device 230; the guide seat 210 has a guide hole 2101; the support rod 220 is slidably inserted into the guide hole 2101; the flying saucer disc 10 is mounted on the support rod 220; the second drive device 230 is configured to drive the support rod 220 to lift and lower, thereby driving the flying saucer disc 10 to lift and lower. The second drive device 230 includes at least one electromagnet 2301 and one magnet 2302; the electromagnet 2301 is disposed at the bottom of the guide seat 210; the magnet 2302 is disposed at the bottom of the support rod 220. The support rod 220 in the lifting assembly can be raised or lowered by controlling the direction of the current flowing through the electromagnet 2301. In turn, the support rod 220 drives the flying saucer disk 10 connected to the support rod 220 to rise or fall. During the process of controlling the lifting assembly to drive the flying saucer disk 10 to fall, the direction of the current flowing through the electromagnet 2301 is opposite to the direction of the current flowing through the electromagnet 2301 during the process of controlling the lifting assembly to drive the flying saucer disk 10 to rise.

[0068] The specific installation position of the liftable component 200 is not limited to that described in this application. In one example of this application, the winding body 2110 has the annular structure 2112. The liftable component 200 is supported on the first rotating plate 50 and extends at least partially through the hollow region 21102 of the annular structure 2110 to the second rotating plate 60, and is then connected to the saucer disc 10 located above the second rotating plate 60. Specifically, the guide seat 210 of the liftable component 200 is mounted on the first rotating plate 50; the support rod 220 extends upward from the guide seat 210, passes through the hollow region 21102 of the annular winding body 2110 and the second rotating plate 60, and its upper end is connected to the saucer disc 10.

[0069] In another example of this application, the winding body 2110 has the annular structure 2112. The liftable assembly 200 is supported on the base 40 and extends at least partially through the first rotating plate 50, the hollow region 21102 of the annular structure 2110, to the second rotating plate 60, and then connects to the saucer disc 10 located above the second rotating plate 60. Specifically, the guide seat 210 of the liftable assembly 200 is mounted on the base 40; the support rod 220 extends upward from the guide seat 210, through the first rotating plate 50, the hollow region 21102 of the annular winding body 2110, and the second rotating plate 60, and its upper end is connected to the saucer disc 10. In one specific embodiment of this application, the guide seat 210 is mounted on the base 40, and the first driving device 70 is mounted on the base 40; the drive shaft of the first driving device 70 and the support rod 220 correspond to the hollow region 21102 of the annular structure 2110; the drive shaft of the first driving device 70 is hollow inside, and the support rod 220 passes through the drive shaft of the first driving device 70 from the guide seat 210, and then passes through the first rotating plate 50, the hollow region 21102 of the annular winding body 2110 and the second rotating plate 60, and its upper end is connected to the flying saucer disk 10.

[0070] In yet another example of this application, the liftable assembly 200 is supported on the second rotating plate 60 and connected to the flying saucer disk 10. Specifically, the guide seat 210 of the liftable assembly 200 is mounted on the second rotating plate 60. The support rod 220 extends upward from the guide seat 210, and its upper end is connected to the flying saucer disk 10.

[0071] The automatically opening and closing vehicle cover also includes a controller for controlling the state switching of the automatically opening and closing vehicle cover. Specifically, during the process of the controller controlling the automatically opening and closing vehicle cover to switch from a closed state to an unfolded state, the controller first drives the flying saucer disk to rise by controlling the lifting component 200; then it drives the first rotating plate 50 to rotate by controlling the first driving device 70, thereby driving the winding component 21 to rotate, until the positioning component 100 recognizes that the first rotating plate 50 has reached a preset position; then it controls the air pump 30 to inflate the air tube 22 until the air tube 22 expands to be fully unfolded and drives the cover 23 connected to the air tube 22 to be fully unfolded. During the process of the controller controlling the automatically opening and closing vehicle cover to switch from the unfolded state to the retracted state, the controller first controls the air pump 30 to evacuate the air pipe 22 until the air pipe 22 and the cover 23 are completely contained in the internal space of the flying saucer disc. Then, the controller controls the first drive device 70 to drive the first rotating plate 50 to rotate, thereby driving the winding assembly 20 to rotate. Finally, the controller controls the lifting assembly 200 to drive the flying saucer disc 10 to descend.

[0072] The automatically opening and closing car cover will be further illustrated below through several specific embodiments. Example 1

[0073] like Figure 3 and Figure 4 As shown, the automatically opening and closing vehicle cover includes a base 40, on which a first driving device 70 and an infrared switch 160 are mounted. A first power supply device 80 is configured to provide energy to the first driving device 70, enabling the first driving device 70 to operate. The first driving device 70 can be a motor or other device capable of rotational motion. The first power supply device 80 can be a battery mounted on the base 40 or a connected power battery or starting battery of the vehicle itself. A first rotating plate 50 is driven by the first driving device 70 to rotate. A light-shielding block 170 is provided on the lower end surface of the first rotating plate 50. The light-shielding block 170 rotates together with the first rotating plate 50. When the light-shielding block 170 blocks the infrared light emitted by the infrared switch 160, the infrared switch 160 is triggered.

[0074] A coiled body 2110, made of rigid material, is fixed to the first rotating plate 50 and moves synchronously with it. At least three air vents are provided on the outer periphery of the coiled body 2110, arranged in a triangular pattern around the longitudinal central axis L1 of the coiled body 2110. Each air vent is connected to a strip-shaped inflation tube 22. Each pair of adjacent inflation tubes 22 is connected to each other by a cover 23, which is also partially fixed to the outer periphery of the coiled body 2110 using Velcro. The inflation tubes 22 form the framework of the automatically opening and closing car cover. The outer surface of the cover 23 is coated with a highly reflective material to further improve the sunshade effect of the car cover. The coiled body 2110 extends from the center between the plurality of inflation tubes 22. The coiled body 2110 has a columnar structure 2111, which is made of rigid material.

[0075] A second rotating plate 60 is fixed to the top of the winding body 2110. The first rotating plate 50 and the second rotating plate 60 define the upper and lower limits of a storage space 5601. The inflation tube 22 and the cover 23 are stored in the storage space 5601 and are wound around the outside of the winding assembly 21. The winding assembly 21 is the winding shaft for the inflation tube 22 and the cover 23.

[0076] A guide seat 210 is provided at the center of the upper surface of the second rotating plate 60. A guide hole 2101 is provided at the center of the guide seat 210. An electromagnet 2301 is provided at the bottom of the guide hole 2101. A support rod 220 is inserted into the guide hole 2101 and can move freely up and down along the guide hole 2101. A magnet 2302 is provided at the lower end of the support rod 220. By controlling the polarity of the electromagnet 2301, the support rod 220 can be fixed or lifted. The top end of the support rod 220 is connected to an arc-shaped flying saucer disc 10. The flying saucer disc 10 is driven by the support rod 220 to move up and down. When the inflation tube 22 and the cover 23 are completely retracted, the flying saucer disc 10 is lowered to its lowest position, thereby completely covering the entire winding assembly 21, inflation tube 22, cover 23, first rotating plate 50, second rotating plate 60, base 40, etc., installed on the roof of the vehicle. Because the flying saucer disc 10 is arc-shaped, it minimizes wind resistance during driving and also serves a decorative purpose, making the vehicle more aesthetically pleasing.

[0077] An air pump 30 is disposed on the upper surface of the second rotating plate 60. The air pump 30 is connected to the winding assembly 21 via an air pipe 31, and can supply air to or draw air from the winding assembly 21. A second power supply device 90 is configured to supply power to the air pump 30 so that the air pump 30 can operate. The second power supply device 90 can be a battery fixed on the second rotating plate 60 and electrically connected to the air pump 30, or it can be an electrically connected functional device or the vehicle's own power battery or starting battery. The electrical connection can be a wired connection or a wireless power transmission.

[0078] The automatically opening and closing car cover also includes a controller. When the controller receives an unfolding command, it first activates the electromagnet 2301 to lift the support rod 220, causing the flying saucer disc 10 to be lifted synchronously; then it activates the first drive device 70 to rotate the first rotating plate 50, causing the rolled-up inflation tube 22 and the cover 23 to unfold. Simultaneously, the light-blocking block 170 rotates with the first rotating plate 50. When the infrared light emitted by the infrared switch 160 is blocked, the infrared switch 160 is triggered, and the first drive device 70 is activated. The movement stops, at which point the inflation tube 22 and the cover 23 are in the correct positions. Then, the air pump 30 is activated, inflating the inflation tube 22 through the winding assembly 21, thus expanding the inflation tube 22 and the cover 23. Once fully expanded, the lower ends of the inflation tube 22 and the cover 23 are pressed against the vehicle body, forming an arched space with the flying saucer disc 10, the inflation tube 22, and the cover 23. The air within this arched space forms a still air layer, providing better heat insulation. When the controller receives a retraction command, it controls the air pump 30 to extract air, causing the inflation tube 22 to contract. The first drive device 70 is activated, causing the first rotating plate 50 to rotate. The inflation tube 22 and the cover 23 are then wound up; during the retraction process, the infrared switch 160 is not activated. After the inflation tube 22 and the cover 23 are fully retracted, the first drive device 70 is stopped, and the current through the electromagnet 2301 is reduced, thereby reducing the thrust of the electromagnet 2301 on the support rod 220. Under the weight of the saucer disc 10 and the support rod 220, the saucer disc 10 and the support rod 220 descend simultaneously. When the saucer disc 10 and the support rod 220 reach their lowest positions, the direction of the current through the electromagnet 2301 is reversed, thereby locking the support rod 220 and completing the car cover's storage. The user only needs to send a command, and the controller can automatically complete the unfolding and storage of the car cover, thus providing the user with a more convenient user experience. Example 2

[0079] like Figure 5 and Figure 6As shown, the automatically opening and closing vehicle cover includes a base 40, on which a first driving device 70 and an infrared switch 160 are mounted. A first power supply device 80 is configured to provide energy to the first driving device 70, enabling the first driving device 70 to operate. The first driving device 70 can be a motor or other device capable of rotational motion. The first power supply device 80 can be a battery mounted on the base 40 or a connected power battery or starting battery of the vehicle itself. A first rotating plate 50 is driven by the first driving device 70 to rotate. A light-shielding block 170 is provided on the lower end surface of the first rotating plate 50. The light-shielding block 170 rotates together with the first rotating plate 50. When the light-shielding block 170 blocks the infrared light emitted by the infrared switch 160, the infrared switch 160 is triggered.

[0080] A guide seat 210 is provided on the first rotating plate 50. A guide hole 2101 is provided at the center of the guide seat 210. An electromagnet 2301 is provided at the bottom of the guide hole 2101. A support rod 220 passes through and is inserted into the guide hole 2101 and can move freely up and down along the guide hole 2101. A magnet 2302 is provided at the lower end of the support rod 220. The support rod 220 can be fixed or lifted by controlling the polarity of the electromagnet 2301 and the current intensity flowing through the electromagnet 2301.

[0081] A winding body 2110, made of flexible material, is fixed to the first rotating plate 50 and moves synchronously with it. The winding body 2110 includes an annular structure 2112, which is also made of flexible material and has an air collection chamber 21101. The support rod 220 passes through the center of the winding body 2110. Four inflatable tubes 22, integrally formed with the winding body 2110, are provided on the outer periphery of the winding body 2110. Each pair of adjacent inflatable tubes 22 is connected to each other by a cover 23, which is also partially fixed to the outer periphery of the winding body 2110 by Velcro. The inflatable tubes 22 constitute the skeleton of the automatically opening and closing car cover. The outer surface of the cover 23 is coated with a highly reflective material to further improve the sunshade effect of the car cover.

[0082] The winding body 2110 extends from the center between the plurality of inflation tubes 22. A rigid limiting ring 213 is fitted around the outer periphery of the winding body 2110. The height of the rigid limiting ring 213 is lower than the height of the winding body 2110 after it is fully inflated. A rigid strip 212 is provided on the outer periphery of the winding body 2110 in contact with the rigid limiting ring 213. The rigid strip 212 and the inner surface of the rigid limiting ring 213 are respectively provided with mutually cooperating protrusions and grooves. The protrusions are inserted into the grooves. Through their interaction, the rigid limiting ring 213 will rotate together with the winding body 2110. The rigid limiting ring 213 has a through hole 2131 at a position corresponding to the inflation tube 22, allowing the inflation tube 22 to pass through. This design ensures that the section of the inflation tube 22 within the outer surface of the rigid limiting ring 213 is rigidly protected by the limiting ring. No matter how the outer cover 23 rolls or pulls, the force is only applied to the outer surface of the rigid limiting ring 213, and cannot reach the root of the inflation tube 22 within the outer surface of the rigid limiting ring 213. This reduces the stress on the root of the inflation tube 22, which is prone to stress concentration, thereby lowering the risk of breakage at that location.

[0083] The top of the rigid limiting ring 213 is connected to a second rotating plate 60. The first rotating plate 50 and the second rotating plate 60 define the upper and lower limits of a storage space 5601. The inflation tube 22 and the cover 23 are stored in the storage space 5601 and are wound around the outside of the rigid limiting ring 213. The rigid limiting ring 213 serves as the winding axis for the inflation tube 22 and the cover 23.

[0084] The second rotating plate 60 has a central through hole 61, through which the winding body 2110 protrudes. The support rod 220 protrudes from the center of the winding assembly 21, and its upper top is connected to an arc-shaped flying saucer disc 10. The flying saucer disc 10 is driven by the support rod 220 to move up and down. After the winding assembly 21 is inflated, its top abuts against the lower surface of the flying saucer disc 10. In the fully unfolded state S1 of the automatically opening and closing car cover, the flying saucer disc 10 is pressed tightly against the upper surface of the winding assembly 21 under the action of the support rod 220 and its own weight.

[0085] An air pump 30 is disposed on the first rotating plate 50 within the area enclosed by the inner wall of the winding assembly 21. The air pump 30 is connected to the winding assembly 21 via an air pipe 31, and can supply air to or draw air from the winding assembly 21. A second power supply device 90 is configured to supply power to the air pump 30 so that the air pump 30 can operate. The second power supply device 90 can be a battery fixed on the first rotating plate 50 and electrically connected to the air pump 30, or it can be an electric power battery or starter battery of the vehicle itself that is electrically connected. The electrical connection can be a wired connection or a wireless power transmission.

[0086] The vehicle cover also includes a controller. When the controller of the automatically opening and closing vehicle cover receives an unfolding command, it first activates the electromagnet 2301 to lift the support rod 220, causing the flying saucer disc 10 to be lifted synchronously; then it activates the first drive device 70 to drive the first rotating plate 50 to rotate, causing the rolled-up inflation tube 22 and the cover 23 to unfold. At the same time, the light-blocking block 170 rotates with the first rotating plate 50. When the infrared light emitted by the infrared switch 160 is blocked, the infrared switch 160 is triggered, and the first drive device 70 stops moving. At this time, the inflation tube 22 and the cover 23... The cover 23 is in the correct position; then the air pump 30 is controlled to operate, inflating the air tube 22 through the winding assembly 21, thereby opening the air tube 22 and the cover 23, and simultaneously lifting the flying saucer disc 10. After the air tube 22 and the cover 23 are fully opened, the lower ends of the air tube 22 and the cover 23 are close to the vehicle body, and the flying saucer disc 10 is close to the top surface of the winding assembly 21, so that the flying saucer disc 10, the air tube 22, and the cover 23 form an arched space. The air in the arched space forms a still air layer, thereby better insulating heat. At this time, part of the support rod 220 is still held in the guide hole 2101, so that the flying saucer disc 10 will not be blown away from the predetermined position by the wind. When the controller receives a retraction command, it controls the air pump 30 to draw air, causing the inflation tube 22 and the winding assembly 21 to contract, and the flying saucer disc 10 to descend. The first drive device 70 is activated, causing the first rotating plate 50 to rotate. The inflation tube 22 and the cover 23 are wound up. During the retraction process, the infrared switch 160 is not activated. After the inflation tube 22 and the cover 23 are completely wound up, the first drive device 70 is stopped, reducing the current through the electromagnet 2301, thereby reducing the thrust of the electromagnet 2301 on the support rod 220. Under the weight of the flying saucer disc 10 and the support rod 220, the flying saucer disc 10 and the support rod 220 descend simultaneously. When the flying saucer disc 10 and the support rod 220 reach their lowest positions, the direction of the current through the electromagnet 2301 is reversed, thereby locking the support rod 220, thus completing the car cover retraction. Users only need to send commands, and the controller can automatically unfold and retract the car cover, thus providing users with a more convenient user experience. Example 3

[0087] like Figure 7 and Figure 8As shown, the automatically opening and closing vehicle cover includes a base 40, on which a first driving device 70 and an infrared switch 160 are mounted. A first power supply device 80 is configured to provide energy to the first driving device 70, enabling the first driving device 70 to operate. The first driving device 70 can be a motor or other device capable of rotational motion. The first power supply device 80 can be a battery mounted on the base 40 or a connected power battery or starting battery of the vehicle itself. A first rotating plate 50 is driven by the first driving device 70 to rotate. A light-shielding block 170 is provided on the lower end surface of the first rotating plate 50. The light-shielding block 170 rotates together with the first rotating plate 50. When the light-shielding block 170 blocks the infrared light emitted by the infrared switch 160, the infrared switch 160 is triggered.

[0088] A guide seat 210 is provided on the first rotating plate 50. A guide hole 2101 is provided at the center of the guide seat 210. An electromagnet 2301 is provided at the bottom of the guide hole 2101. A support rod 220 is inserted into the guide hole 2101 and can move freely up and down along the guide hole 2101. A magnet 2302 is provided at the lower end of the support rod 220. The support rod 220 can be fixed or lifted by controlling the polarity of the electromagnet 2301 and the current intensity flowing through the electromagnet 2301.

[0089] A winding body 2110, made of flexible material, is fixed to the first rotating plate 50 and moves synchronously with it. The winding body 2110 includes an annular structure 2112, which is also made of flexible material and has an air collection chamber 21101. The support rod 220 passes through the center of the winding body 2110. Four inflatable tubes 22, integrally formed with the winding body 2110, are provided on the outer periphery of the winding body 2110. Each pair of adjacent inflatable tubes 22 is connected to each other by a cover 23, which is also partially fixed to the outer periphery of the winding body 2110 by Velcro. The inflatable tubes 22 constitute the skeleton of the automatically opening and closing car cover. The outer surface of the cover 23 is coated with a highly reflective material to further improve the sunshade effect of the car cover.

[0090] The winding body 2110 extends from the center between the plurality of inflation tubes 22. A rigid strip 212 is provided on the outer periphery of the winding body 2110, the height of which is lower than the height of the winding body 2110 when fully inflated. A second rotating plate 60 is connected to the top of the rigid strip 212. The first rotating plate 50 and the second rotating plate 60 define the upper and lower limits of a storage space 5601. The inflation tubes 22 and the cover 23 are stored in the storage space 5601 and are wound around the outside of the rigid strip 212. The rigid strip 212 serves as the winding axis for the inflation tubes 22 and the cover 23.

[0091] The second rotating plate 60 has a central through hole 61, through which the winding body 2110 protrudes. The support rod 220 protrudes from the center of the winding body 2110, and its upper top is connected to an arc-shaped flying saucer disc 10. The flying saucer disc 10 is driven by the support rod 220 to move up and down. After the winding body 2110 is inflated, its top abuts against the lower surface of the flying saucer disc 10. In the fully unfolded state S1 of the automatically opening and closing car cover, the flying saucer disc 10 is pressed tightly against the upper surface of the winding body 2110 under the action of the support rod 220 and its own weight.

[0092] An air pump 30 is disposed on the first rotating plate 50 within the area enclosed by the inner wall of the winding body 2110. The air pump 30 is connected to the winding body 2110 via an air pipe 31, and can supply air to or draw air from the winding body 2110. A second power supply device 90 is configured to supply power to the air pump 30 so that the air pump 30 can operate. The second power supply device 90 may be a battery fixed on the first rotating plate 50 and electrically connected to the air pump 30, or it may be an electrically connected power battery or starter battery of the vehicle itself. The electrical connection may be a wired connection or a wireless power transmission.

[0093] The vehicle cover also includes a controller. When the controller of the automatically opening and closing vehicle cover receives an unfolding command, it first activates the electromagnet 2301 to lift the support rod 220, causing the flying saucer disc 10 to be lifted synchronously; then it activates the first drive device 70 to drive the first rotating plate 50 to rotate, causing the rolled-up inflation tube 22 and the cover 23 to unfold. At the same time, the light-blocking block 170 rotates with the first rotating plate 50. When the infrared light emitted by the infrared switch 160 is blocked, the infrared switch 160 is triggered, and the first drive device 70 stops moving. At this time, the inflation tube 22 and the cover... 23 is in the correct position; then the air pump 30 is controlled to work, inflating the air tube 22 through the winding body 2110, thereby opening the air tube 22 and the cover 23, and simultaneously lifting the flying saucer disc 10. After the air tube 22 and the cover 23 are fully opened, the lower ends of the air tube 22 and the cover 23 are close to the vehicle body, and the flying saucer disc 10 is close to the top surface of the winding body 2110, so that the flying saucer disc 10, the air tube 22, and the cover 23 form an arched space. The air in the arched space forms a still air layer, thereby better insulating heat.

The first drive device 70 is activated, causing the first rotating plate 50 to rotate. The inflation tube 22 and the cover 23 are rolled up. During the retraction process, the infrared switch 160 is not activated. After the inflation tube 22 and the cover 23 are completely rolled up, the first drive device 70 is stopped, reducing the current through the electromagnet 2301, thereby reducing the thrust of the electromagnet 2301 on the support rod 220. Under the weight of the flying saucer disc 10 and the support rod 220, the flying saucer disc 10 and the support rod 220 descend simultaneously. When the flying saucer disc 10 and the support rod 220 reach their lowest positions, the direction of the current through the electromagnet 2301 is reversed, thereby locking the support rod 220, thus completing the car cover retraction. Users only need to send commands, and the controller can automatically unfold and retract the car cover, thus providing users with a more convenient user experience. Example 4

[0094] like Figure 9 and Figure 10As shown, the automatically opening and closing car cover includes a base 40, on which a first drive device 70 and a photoelectric switch 120 are mounted. A first power supply device 80 is configured to provide energy to the first drive device 70, enabling the first drive device 70 to operate. The first drive device 70 may be a motor or other device capable of rotational motion. The first power supply device 80 may be a battery mounted on the base 40 or a connected power battery or starting battery of the vehicle itself. The photoelectric switch 120 is used to detect whether a detection hole 110 on the base 40 is blocked.

[0095] A first rotating plate 50 is supported above the base 40 by several evenly distributed elastic support devices, and the first rotating plate 50 is driven to rotate by the first driving device 70. The first rotating plate 50 has a through-hole 52, and a light-shielding rod 130 is inserted into the through-hole 52, allowing free movement within it. The lower end of the light-shielding rod 130 has a ball head 150, and a spring 140 is sleeved on the light-shielding rod 130, with one end abutting against the ball head 150 and the other end abutting against the lower end face of the first rotating plate 50. The lower end of the ball head 150 abuts against the base 40. The light-shielding rod 130 rotates with the first rotating plate 50. When the ball head 150 rotates above the detection hole 110, it is pushed by the spring 140 into the detection hole 110, thus blocking the detection hole 110 and triggering the photoelectric switch 120.

[0096] A guide seat 210 is provided on the first rotating plate 50. A guide hole 2101 is provided in the center of the guide seat 210. An electromagnet 2301 is provided at the bottom of the guide hole 2101. A support rod 220 is inserted into the guide hole 2101 and can move freely up and down along the guide hole 2101. A magnet 2302 is provided at the lower end of the support rod 220. The support rod 220 can be fixed or lifted by controlling the polarity of the electromagnet 2301 and the current intensity flowing through the electromagnet 2301.

[0097] A winding body 2110, made of rigid material, is fixed to the first rotating plate 50 and moves synchronously with the first rotating plate 50. The winding body 2110 includes an annular structure 2112, which is also made of rigid material and has an air collection chamber 21101. The support rod 220 passes through the center of the winding body 2110. At least three air vents are provided on the outer periphery of the winding body 2110. The air vents are triangularly distributed around the longitudinal central axis L1 of the winding body 2110. Each air vent is connected to an inflation tube 22. Every two adjacent inflation tubes 22 are connected to each other by a cover 23, which is also partially fixed to the outer periphery of the winding body 2110 by Velcro. The inflation tubes 22 constitute the skeleton of the car cover. The outer surface of the cover 23 is coated with a highly reflective material, thereby further improving the sunshade effect of the car cover. The winding body 2110 extends from the center between the plurality of air tubes 22.

[0098] An air pump 30 is disposed on the first rotating plate 50 within the area enclosed by the inner wall of the winding body 2110. The air pump 30 is connected to the winding body 2110 via an air pipe 31, and can supply air to or draw air from the winding body 2110. A second power supply device 90 is configured to supply power to the air pump 30 so that the air pump 30 can operate. The second power supply device 90 may be a battery fixed on the first rotating plate 50 and electrically connected to the air pump 30, or it may be an electrically connected power battery or starter battery of the vehicle itself. The electrical connection may be a wired connection or a wireless power transmission.

[0099] A second rotating plate 60 is provided on the top of the winding body 2110. The first rotating plate 50 and the second rotating plate 60 define the upper and lower limits of a storage space 5601. The inflation tube 22 and the cover 23 are stored in the storage space 5601 and are wound around the outside of the winding body 2110. The winding body 2110 is the winding shaft for the inflation tube 22 and the cover 23.

[0100] The second rotating plate 60 has a central hole 62. The support rod 220 passes through the center of the winding body 2110 and exits through the central hole 62 of the second rotating plate 60. The top of the support rod 220 is connected to an arc-shaped saucer disc 10, which is driven by the support rod 220 to move up and down. When the inflation tube 22 and the cover 23 are fully retracted, the saucer disc 10 is lowered to its lowest position, thus completely covering the entire winding assembly 21, inflation tube 22, cover 23, first rotating plate 50, second rotating plate 60, and base 40 mounted on the roof. Because the saucer disc 10 is arc-shaped, this minimizes wind resistance during driving and also serves a decorative purpose, making the vehicle more aesthetically pleasing. The cover also includes a controller.

[0101] When the controller of the vehicle cover receives the unfolding command, it first activates the electromagnet 2301 to lift the support rod 220 a certain distance, so that the flying saucer disc 10 is simultaneously lifted a certain distance. Then, it activates the first drive device 70 to drive the first rotating plate 50 to rotate, so that the rolled-up air tube 22 and the cover 23 are unrolled. At the same time, the light-shielding rod 130 rotates with the first rotating plate 50. When it rotates to above the detection hole 110, the spring 140 pushes the light-shielding rod 130 downward, so that the ball head 150 is embedded in the detection hole 110, thereby triggering the photoelectric switch 120 and stopping the movement of the first drive device 70. At this point, the inflation tube 22 and the cover 23 are in the correct positions. Then, the air pump 30 is controlled to operate, inflating the inflation tube 22 through the winding assembly 21, thereby expanding the inflation tube 22 and the cover 23. After the inflation tube 22 and the cover 23 are fully expanded, their lower ends are pressed tightly against the vehicle body, forming an arched space with the flying saucer disc 10, the inflation tube 22, and the cover 23. The air within this arched space forms a still air layer, thus providing better heat insulation. When the controller receives a retraction command, it controls the air pump 30 to extract air, causing the inflation tube 22 to contract. The first drive device 70 is activated, causing the first rotating plate 50 to rotate. The inflation tube 22 and the cover 23 are retracted, and the light-shielding rod 130 also leaves the detection hole 110. After the inflation tube 22 and the cover 23 are fully retracted, the first drive device 70 is stopped, and the current through the electromagnet 2301 is reduced, thereby reducing the thrust of the electromagnet 2301 on the support rod 220. Under the weight of the saucer disc 10 and the support rod 220, the saucer disc 10 and the support rod 220 descend simultaneously. When the saucer disc 10 and the support rod 220 reach their lowest positions, the direction of the current through the electromagnet 2301 is reversed, thereby locking the support rod 220 and completing the car cover's storage. The user only needs to send a command, and the controller can automatically complete the unfolding and storage of the car cover, thus providing the user with a more convenient user experience.

[0102] Based on the working method of the automatically opening and closing vehicle cover, this application also proposes a control method for the automatically opening and closing vehicle cover, including the following steps: S1, inflating the air tube by controlling the air pump until the air tube expands to fully unfold and drives the cover connected to the air tube to fully unfold.

[0103] In one embodiment of this application, the control method for the automatically opening and closing car cover further includes step S0 before step S1: driving the flying saucer disc to rise by controlling the lifting component.

[0104] In one embodiment of this application, S0 includes the step of: controlling the support rod in the lifting assembly to rise by controlling the working parameters of the electromagnet in the lifting assembly, thereby driving the flying saucer connected to the support rod to rise, wherein the working parameters of the electromagnet include the current direction and current magnitude of the current flowing through the electromagnet.

[0105] In one embodiment of this application, the control method for the automatically opening and closing car cover further includes step S01 after step S0 and before step S1: controlling the first driving device to drive the first rotating plate to rotate, thereby driving the winding assembly to rotate, until the positioning assembly recognizes that the first rotating plate has reached a preset position.

[0106] In one embodiment of this application, the control method for the automatically opening and closing vehicle cover further includes step S2 after step S1: controlling the air pump to draw air from the inflation tube until the inflation tube and the cover are completely contained within the internal space of the flying saucer disc.

[0107] In one embodiment of this application, the control method for the automatically opening and closing vehicle cover further includes step S3 after step S2: driving the flying saucer disc to descend by controlling the lifting assembly. Step S3 includes the following steps: controlling the support rod in the lifting assembly to descend by controlling the operating parameters of the electromagnet in the lifting assembly, thereby driving the flying saucer disc connected to the support rod to descend, wherein the direction of the current flowing through the electromagnet during the process of controlling the lifting assembly to drive the flying saucer disc to descend is opposite to the direction of the current flowing through the electromagnet during the process of controlling the lifting assembly to drive the flying saucer disc to ascend.

[0108] In one embodiment of this application, the control method for the automatically opening and closing vehicle cover includes step S23 after step S2 and before step S3: controlling the first driving device to drive the first rotating plate to rotate, thereby driving the winding assembly to rotate, until the inflation tube and the cover are completely housed in the built-in space of the flying saucer disc.

[0109] In one example of this application, the control method for the automatically opening and closing car cover includes the following steps: S0, driving the flying saucer disc upward by controlling the lifting assembly; S01, driving the first rotating plate to rotate by controlling the first driving device, thereby driving the winding assembly to rotate, until the positioning assembly detects that the first rotating plate has reached a preset position; S1, controlling the air pump to inflate the inflation tube until the inflation tube expands to fully unfold and drives the cover connected to the inflation tube to fully unfold; S2, controlling the air pump to evacuate the inflation tube until the inflation tube and the cover are completely housed in the internal space of the flying saucer disc; S23, driving the first rotating plate to rotate by controlling the first driving device, thereby driving the winding assembly to rotate; S3, driving the flying saucer disc downward by controlling the lifting assembly.

[0110] In summary, the automatically opening and closing vehicle cover of this application is explained. The automatically opening and closing vehicle cover utilizes a flexible and efficient pneumatic energy-charging structure to achieve smooth unfolding of the vehicle cover. The structure is relatively lightweight and simplified, which can not only significantly reduce the physical weight and driving energy consumption of the entire unfolding frame, but also greatly reduce the risk of mechanical stress tearing and jamming during the stretching process, improve the smoothness of automatic closure and the overall reliability of the vehicle cover, and extend the life of the vehicle cover.

[0111] In summary, the objectives of this invention have been fully and effectively achieved. Embodiments have been shown and described to illustrate the functional and structural principles of this invention, and changes may be made without departing from these principles.
