Description

Technical Field

[0001] This application relates to the technical field of automotive parts, and in particular to a vehicle front trunk cover, a method of using the cover, and a vehicle. Background Technology

[0002] With the rapid development of new energy vehicles, the front trunk has become a standard feature in pure electric vehicles, providing users with additional storage space. However, due to its open structure and lack of privacy, items are directly exposed inside, affecting the aesthetics and privacy of the vehicle's interior. Furthermore, the front trunk's location at the front of the vehicle requires users to stand in front of the car and lean forward to access items. The front bumper easily accumulates stubborn dirt such as dust, oil, and insect remains during driving, and clothing easily comes into contact with the bumper surface, resulting in soiled clothing that is difficult to clean. These issues have become major pain points affecting the user experience of the front trunk.

[0003] Traditional technologies already include various shielding or protective devices related to vehicle storage spaces, primarily including sunshades for windows, clothing and bumper protection devices for the trunk loading area, and automatic cargo covers for the trunk. The curtains of these devices are all arranged along the opening of the storage space, and when pulled out, they cover the opening, their effective boundary being limited to the opening of the storage space itself. Regarding the problem of dirty bumpers, existing technologies follow the logic of "reducing the degree of user probing to lower the probability of contact," that is, by improving the ease of operation of the cargo cover (such as electric extension and retraction, automatic opening and closing) to shorten the user's operation time in the bumper area or reduce the degree of forward leaning, thereby indirectly reducing the possibility of clothing coming into contact with the bumper.

[0004] However, traditional cargo covers or protective devices follow the conventional design principle of "covering the storage space opening." The cover is only used to shield items inside the storage space, and its effective boundary is always limited to the opening area. Regarding the issue of dirty bumpers, the traditional solution is to indirectly reduce the probability of contact by minimizing the extent to which the user's body enters the storage space, rather than using the cover itself as a protective layer over the bumper surface. When users need to retrieve items from the front trunk, the lack of effective physical barriers on the front bumper surface means that the risk of clothing coming into direct contact with the bumper surface remains. Summary of the Invention

[0005] This application provides a vehicle front trunk cover, a method for using the cover, and a vehicle. It has the advantages of effectively isolating dirt from the front bumper to prevent users' clothing from being contaminated when operating the front trunk, while also protecting the privacy of items in the front trunk and improving ease of use.

[0006] In a first aspect, embodiments of this application provide a cargo cover for a vehicle's front trunk, comprising:

[0007] The curtain body is a flexible, rollable structure;

[0008] Hook assemblies are disposed at both ends of the curtain body and can be selectively hooked at a first hooking position or a second hooking position.

[0023] In one possible implementation, the automatic winding mechanism further includes a locking mechanism and an unlocking element;

[0024] The locking mechanism cooperates with the reel to lock the circumferential rotation of the reel; the unlocking component cooperates with the locking mechanism to release the locking mechanism from locking the reel.

[0025] Secondly, embodiments of this application provide a vehicle that utilizes the aforementioned vehicle front trunk cover, comprising the following steps:

[0026] Pull out and unfold the curtain body to cover the front trunk opening area, and hook the first hook and the second hook to the side wall hanging points on both sides of the front trunk respectively.

[0027] Alternatively, pull out and unfold the curtain body, spread the curtain body on the outer surface area of ​​the front bumper, and hook the first hook and the second hook onto the same horizontal bar of the front bumper grille.

[0028] Thirdly, embodiments of this application provide a vehicle, including:

[0029] The vehicle body has a front trunk and a front bumper at the front, the side wall of the front trunk has a first hook-up structure, and the grille of the front bumper has a second hook-up structure.

[0042] The accompanying drawings illustrate specific embodiments of this application, which will be described in more detail below. These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0043] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0044] Existing vehicle front trunk cover curtains typically consist of a curtain body positioned at the opening of the front trunk to conceal items inside. These curtains are generally arranged along the direction of the front trunk opening; when pulled out, they cover the opening area, their effective boundary limited to the opening of the storage space itself. To use them, the user pulls the curtain out from one side of the front trunk and secures it to the opposite side, thus concealing items inside the trunk and preventing them from being exposed to the outside view.

[0045] Based on the above scenarios, it is clear that in traditional technology, while covering the front trunk opening area with a curtain can partially conceal items inside the trunk, the curtain's effective boundary is always limited to the area above the trunk opening. This only provides cover from above and cannot fundamentally solve the problem of exposed items affecting aesthetics and privacy. Furthermore, when users retrieve items from the trunk, they typically need to stand in front of the vehicle and lean forward. In this position, clothing is likely to come into contact with the front bumper surface. Since existing cargo covers only cover the trunk opening area and cannot extend to the front bumper surface to provide physical separation, the lack of effective physical separation means that the risk of direct contact between clothing and the bumper surface remains constant. This leads to soiled and difficult-to-clean clothing, severely impacting the user experience.

[0046] The vehicle front trunk cover provided in this application features hook assemblies at both ends of the curtain body, allowing the hook assemblies to be selectively attached to either a first or a second attachment position. When the hook assemblies are attached to the first attachment position, the curtain body covers the front trunk opening area, thus providing a trunk cover. When the hook assemblies are attached to the second attachment position, the curtain body extends onto the outer surface of the front bumper, forming a flat physical protective surface on the front bumper. The user's clothing contacts the curtain body rather than directly contacting the front bumper, effectively concealing items in the front trunk to protect aesthetics and privacy, while also creating a physical barrier on the front bumper surface. This physically solves the problem of users' clothing getting dirty from contact with the front bumper surface, significantly improving the user experience.

[0047] The technical solution of this application and how the technical solution of this application solves the above-mentioned technical problems are described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this application will be described below with reference to the accompanying drawings.

[0048] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4This application discloses a cargo cover for a vehicle's front trunk 3, comprising a curtain body 1 and hook assemblies. The curtain body 1 is a flexible, rollable structure, and the hook assemblies are disposed at both ends of the curtain body 1. The hook assemblies can be selectively attached to a first attachment position or a second attachment position. When the hook assemblies are attached to the first attachment position, the curtain body 1 covers the opening area of ​​the front trunk 3; when the hook assemblies are attached to the second attachment position, the curtain body 1 extends over the outer surface area of ​​the front bumper 5.

[0049] When the user needs to use the cargo cover, first open the hood 4 at the front of the vehicle to expose the opening area of ​​the front trunk 3. Then, the user can pull out and attach the cargo cover as needed. The installation and use of the cargo cover are completed inside the front trunk 3 and outside the front bumper 5, without involving any modification or connection to the hood 4 itself.

[0050] The curtain body 1 is a flexible material layer used for shielding or protection. The flexible rollable structure refers to the physical property of the curtain body 1 that allows it to be rolled up or unfolded, making it easy to store and deploy.

[0051] The hook assembly is a connecting device used to fix the curtain body 1 in a specific position. It includes one or more hook-shaped parts that can be connected to corresponding attachment points on the vehicle.

[0052] The first attachment point is a pre-set position inside the front trunk 3 or at the edge of its opening for fixing the curtain body 1, used to cover items inside the front trunk 3. The second attachment point is a pre-set position on the outer surface area of ​​the front bumper 5 for fixing the curtain body 1, used as a protective layer to cover the surface of the front bumper 5.

[0053] The front trunk 3 opening area is the area at the top of the front trunk 3 used for storing and retrieving items. The front bumper 5 outer surface area refers to the visible outer surface of the front bumper of the vehicle.

[0054] In this embodiment, the curtain body 1 is a flexible rollable structure made of a flexible material. This flexible material can be abrasion-resistant textile fabric, PVC-coated fabric, nylon fabric, or composite material, possessing characteristics of wear resistance, water resistance, and easy cleaning. The flexible rollable structure allows the curtain body 1 to be rolled up or folded for storage and deployment. This rolling operation can be performed manually, for example, by manually rolling up or unfolding the curtain body 1; or it can be performed electrically, for example, by connecting one end of the curtain body 1 to a motor-driven roller, allowing the user to drive the motor to rotate forward or backward by pressing a control button, causing the roller to automatically roll up or unfold the curtain body 1.

[0055] In a preferred embodiment, the hook assembly includes a first hook and a second hook, which are respectively fixed to opposite ends of the curtain body 1. The hooks can be made of elastic plastic or metal and bent to ensure connection strength while having a certain elastic deformation capacity, facilitating connection and detachment from vehicle attachment points.

[0056] The hook assembly can be selectively attached to either a first attachment point or a second attachment point. Specifically, the first attachment point can be located on the side wall inside the front trunk 3, such as the side wall attachment points on both sides of the front trunk 3; the second attachment point can be located on the external structure of the front bumper 5, such as on the same horizontal bar of the grille of the front bumper 5. By connecting the hook assembly to different preset attachment points, two different usage modes can be achieved.

[0057] When the hook assembly is engaged at the first engagement position, the curtain body 1 covers the opening area of ​​the front trunk 3. In this mode, the curtain body 1 is unfolded and covers the top of the opening of the front trunk 3, forming a flat covering surface, thereby blocking external views, protecting the privacy of items inside the front trunk 3, and improving the cleanliness and aesthetics of the vehicle interior.

[0058] When the hook assembly is engaged at the second engagement position, the curtain body 1 extends onto the outer surface area of ​​the front bumper 5. In this mode, the curtain body 1 is pulled out and spread across the surface of the front bumper 5, forming a smooth physical protective surface. When the user needs to retrieve or place items in the front trunk 3, the user stands in front of the vehicle and leans forward; the clothing contacts the curtain body 1 rather than the surface of the front bumper 5, thus preventing direct contact between the clothing and dirt such as dust, oil, and insect remains on the front bumper 5.

[0059] Through the above technical solution, the flexible and rollable characteristics of the curtain body 1 and the design of the hook assembly being selectively attached to either the first or second attachment position achieve dual functions. When the curtain body 1 covers the opening area of ​​the front trunk 3, it effectively conceals the items inside the front trunk 3, protecting the privacy of the items and the aesthetics of the vehicle interior. When the curtain body 1 is spread out on the outer surface area of ​​the front bumper 5, it provides direct physical isolation protection for the user, preventing the user's clothing from coming into contact with dirt on the surface of the front bumper 5, and significantly improving the user experience when taking items out of the front trunk 3.

[0060] This application further proposes a specific implementation of the hook assembly, which includes a first hook and a second hook, which are respectively fixed to opposite ends of the curtain body 1; when the hook assembly is attached to the first attachment position, the first hook and the second hook are respectively attached to the side wall attachment points on both sides of the front trunk 3; when the hook assembly is attached to the second attachment position, the first hook and the second hook are respectively attached to the same horizontal bar of the grille of the front bumper 5.

[0061] Specifically, the hook assembly consists of two independent hooks, a first hook and a second hook, which are respectively fixed to opposite ends of the curtain body 1, such as the left and right edges of the curtain body 1. The first and second hooks can be fixed to the curtain body 1 by sewing, riveting, gluing, or integral molding to ensure a firm and reliable connection. The hooks are made of elastic plastic or metal, bent into a hook-like structure to fit the shape of the hanging point, ensuring connection strength while possessing a certain degree of elastic deformation capability, facilitating connection and detachment from the vehicle's hanging point.

[0062] When the curtain body 1 needs to cover the opening area of ​​the front trunk 3, the hook assembly is engaged at the first engagement position. At this time, the first hook and the second hook are respectively connected to the side wall mounting points on both sides of the interior of the front trunk 3. The side wall mounting points can be preset holes, protrusions, or slots for the hook assembly to hook or engage.

[0063] When the curtain body 1 needs to be laid out on the outer surface area of ​​the front bumper 5, the hook assembly is engaged at the second engagement position. At this time, the first hook and the second hook are respectively engaged on the same horizontal bar of the front bumper 5 grille. The horizontal bar of the front bumper 5 grille usually has a certain strength and stability, and can serve as a reliable engagement point for the hook assembly to hook or clamp.

[0064] Through the above technical solution, the hook assembly is specified as two independent hooks, a first hook and a second hook, and the specific connection methods for two different hooking positions are clarified. The first hook and the second hook are respectively fixed to both ends of the curtain body 1 and hooked to the side wall hook points on both sides of the front trunk 3 or to the same horizontal bar of the front bumper 5 grille. This dual-point support hooking method significantly enhances the stability of the curtain body 1 in both usage modes compared to a single hooking point. Whether covering items inside the front trunk 3 or spreading out on the outer surface of the front bumper 5, the curtain body 1 remains flat and is not easily loosened, allowing users to intuitively and quickly complete the hooking operation when switching the usage modes of the curtain body 1, thus fully utilizing the multi-functionality of the vehicle's front trunk 3 cargo cover.

[0065] This application further proposes that both the first hook and the second hook have a bent portion that is adapted to the shape of the same horizontal bar of the front grille, and a clamping space is formed on the inner side of each bent portion. The first hook and the second hook are elastically clamped to the same horizontal bar through the corresponding clamping space. At the same time, both the first hook and the second hook have a hook portion that is adapted to the shape of the side wall hanging point. The first hook and the second hook are respectively hooked to the side wall hanging points on both sides of the front trunk 3 through the corresponding hook portion.

[0066] Specifically, both the first and second hooks have a bent portion that is part of the hook itself. This bent portion is specially designed to closely fit the outer contour of a specific crossbar on the front bumper grille. For example, the bent portion can be integrally molded from metal wire, engineering plastic, or composite materials, and its curvature, opening size, and depth can be precisely designed according to the actual size and shape of the target crossbar. If the crossbar has a circular cross-section, the bent portion can be designed as a semi-circular groove; if it has a rectangular cross-section, it can be designed as a U-shaped or C-shaped groove. This adaptability ensures maximum contact area between the hook and the crossbar, thereby improving the stability of the connection.

[0067] Each bend has an inner clamping space, which is an area formed inside the bend to accommodate and fix the crossbar. It is typically an open or semi-closed cavity, slightly smaller than or equal to the corresponding size of the crossbar, to provide some coverage or constraint during attachment. For example, the clamping space can be defined and optimized by providing protrusions, grooves, or elastic pads on the inside of the bend to enhance the fixation of the crossbar.

[0068] The first and second hooks are elastically clamped to the same crossbar through corresponding clamping spaces. Elastic clamping refers to the hooks applying pressure to the crossbar through their own elastic deformation or the action of internal elastic elements when hooked, achieving a tight and stable fixation. Various methods can be used to achieve elastic clamping. In some embodiments, the hook material itself can have a certain degree of elasticity, such as using engineering plastics or spring steel with good elasticity, allowing the bent portion to slightly open when hooked and spring back to tighten after the crossbar enters the clamping space, thus firmly clamping the crossbar. In some embodiments, elastic pads, such as rubber or silicone, can be placed on the inner wall of the clamping space. These pads deform when compressed, generating a reaction force to tightly fix the crossbar. In some embodiments, a micro-spring mechanism can be integrated inside the hook. When the hook is hooked, the spring is compressed, generating a continuous clamping force. This elastic clamping mechanism effectively prevents the hooks from loosening or falling off due to vehicle vibration.

[0069] Both the first and second hooks have hook portions that conform to the shape of the side wall attachment points. These hook portions are another part of the hooks, specifically designed to match the attachment points on the side walls of the front trunk 3. The shape of the hook portion depends on the specific form of the side wall attachment point. For example, if the side wall attachment point is a ring or rod-shaped structure, the hook portion can be designed as a C-shaped or J-shaped hook for quick insertion and removal. If the side wall attachment point is a hole or groove, the hook portion can be designed as a pin-type hook with barbs or an expansion structure to provide stronger holding force. The first and second hooks are respectively attached to the side wall attachment points on both sides of the front trunk 3 via corresponding hook portions. The attachment process is usually manual; the user aligns the hook portion with the side wall attachment point and applies appropriate force to engage them. The design of the hook portion should consider ease of operation; for example, it can be designed to allow for attachment and removal with one hand. To improve the stability of the hook, the hook may include auxiliary structures such as anti-drop buckles and limiting protrusions to prevent accidental detachment due to bumps during vehicle operation.

[0070] Through the above technical solution, when the hook assembly is attached to the same horizontal bar of the front bumper grille, it can achieve elastic clamping of the horizontal bar through the clamping space formed by the bend portion adapted to the shape of the horizontal bar and its inner side. This effectively prevents the hook from loosening or falling off due to vibration during vehicle operation. It can adapt to the possible dimensional tolerances of the horizontal bar, providing a tighter fit, and significantly improving the installation stability and reliability of the cargo cover when spread on the outer surface area of ​​the front bumper 5. For the side wall hanging points on both sides of the front trunk 3, hook parts with adapted shapes are set to ensure that the hooks can be firmly and conveniently attached to the side wall hanging points. This ensures that the curtain body 1 remains stable when covering the opening area of ​​the front trunk 3, avoiding the cargo cover from affecting the use effect or causing safety hazards due to insecure attachment, thus improving the user experience and practicality of the product.

[0071] This application further proposes that the length of the curtain body 1 is greater than the length of the opening of the front trunk 3, and the width of the curtain body 1 is greater than the width of the opening of the front trunk 3; the edge of the curtain body 1 is provided with a reinforcing structure along the circumference of the curtain body 1.

[0072] Specifically, the length of the curtain body 1 is greater than the length of the opening in the front trunk 3, and the width of the curtain body 1 is greater than the width of the opening in the front trunk 3. This ensures that when the curtain body 1 covers the area of ​​the opening in the front trunk 3, both its length and width can exceed the boundary of the opening, forming a certain overlap. This design ensures that the curtain body 1 can completely and tightly cover the opening in the front trunk 3, avoiding gaps due to insufficient size, and providing sufficient attachment area for fixing the edges of the curtain body 1.

[0073] The edge of the curtain body 1 is reinforced with a circumferential structure. This reinforcement structure refers to the components or treatment methods installed along the outer periphery of the curtain body 1 to enhance its edge strength and resistance to deformation. This reinforcement structure can be implemented in various forms, such as by sewing binding tape into the edge area, folding and sewing the edge, or installing reinforcing strips at the edge through heat pressing. While ensuring the curtain body 1 possesses overall flexible and rollable characteristics, enhancing the structural strength of the curtain body 1's edges effectively prevents curling, sagging, or irregular deformation of the edges when repeatedly stretched, spread, or subjected to external wind forces, thus maintaining the flatness and shape stability of the curtain body 1.

[0074] Through the above technical solution, the length and width of the curtain body 1 are both greater than the corresponding dimensions of the opening of the front trunk 3, ensuring that the curtain body 1 can completely cover the opening area of ​​the front trunk 3 and form a full overlap, effectively avoiding gaps caused by insufficient size, and improving the sealing and dustproof effect of the cargo cover. The reinforcing structure set along the circumferential direction of the edge of the curtain body 1 significantly enhances the structural strength of the edge of the curtain body 1, effectively preventing the edge of the curtain body 1 from curling or deforming when stretched, spread out, or subjected to external forces, ensuring that the curtain body 1 can maintain a flat spread-out state under different usage scenarios, thereby providing stable and reliable shielding and protection functions.

[0075] This application further proposes a cargo cover for a vehicle front trunk 3, which also includes a housing and an automatic retraction mechanism 2. The automatic retraction mechanism 2 is disposed inside the housing, and the curtain body 1 is rolled up and installed on the automatic retraction mechanism 2. The housing has an opening, and the free end of the curtain body 1 extends out of the housing through the opening. When the curtain body 1 is in the retracted state, it is completely contained inside the housing.

[0076] Specifically, the housing provides physical protection for the automatic retraction mechanism 2 and the curtain body 1, protecting them from dust, moisture, and external mechanical damage, thus helping to maintain the cleanliness and aesthetics of the interior of the front trunk 3. The housing structure is designed to fit the installation space of the vehicle's front trunk 3.

[0077] The automatic winding mechanism 2 is used to realize the pulling out and automatic retraction of the curtain body 1. The curtain body 1 is wound and installed on the automatic winding mechanism 2, and the fixed end of the curtain body 1 is fixedly connected to the roller. When the curtain body 1 is pulled out, the curtain body 1 unfolds from the roller; when the curtain body 1 is released, the roller rotates in the opposite direction under the drive of the coil spring, and neatly winds the curtain body 1 around the outer circumference of the roller.

[0078] The housing has an opening, typically a narrow slot, the size and shape of which match the thickness and width of the curtain body 1. This ensures that the curtain body 1 can smoothly extend or retract through the opening while minimizing the entry of external debris into the housing. The free end of the curtain body 1 extends outside the housing through the opening. This free end is used to install a hook assembly, allowing the user to grip and pull it out to the desired position, hooking it at a first hooking position or a second hooking position.

[0079] When the curtain body 1 is not in use, the automatic retraction mechanism 2 retracts it completely into the housing. The complete storage design effectively protects the curtain body 1 from contamination or damage, making the interior space of the front trunk 3 more tidy and preventing the loose curtain body 1 from taking up space or affecting the placement of other items.

[0080] By introducing the housing and automatic retraction mechanism 2 through the above technical solution, the problems of inconvenient storage, easy damage, and insufficient smooth operation of the curtain body 1 when not in use are effectively solved. The automatic retraction mechanism 2 ensures that the curtain body 1 can be smoothly pulled out when needed and automatically retracted into the housing when released, improving the convenience of user operation. The housing provides comprehensive physical protection for the curtain body 1 in the retracted state, avoiding damage to the curtain body 1 from dust, dirt, and accidental collisions, and extending the service life of the product. The design of the curtain body 1 being completely housed inside the housing allows the cargo cover to blend into the interior environment of the vehicle's front trunk 3 when not in use, improving the overall tidiness.

[0081] This application further proposes that the aforementioned automatic winding mechanism 2 includes a roller and a coil spring. The fixed end of the curtain body 1 is fixedly connected to the roller, and the curtain body 1 is wound around the outer circumference of the roller. The coil spring is disposed in the inner cavity of the roller, with one end fixedly connected to the roller and the other end fixedly connected to the housing.

[0082] Specifically, the roller is a rod-shaped component with a cylindrical or polygonal cross-section, used to provide a core support for the curtain body 1, enabling the curtain body 1 to be rolled up and unfolded smoothly and orderly.

[0083] The roller can be made of metal (such as aluminum alloy or steel) or high-strength plastic, and its surface can be designed to be smooth or textured to increase friction with the curtain body 1 and ensure the stability of the winding. Bearings or brackets are usually provided at both ends of the roller to allow for smooth rotation inside the housing.

[0084] A coil spring is a helical elastic element that stores and releases energy through its elastic deformation, thereby providing driving force for the automatic winding mechanism 2. When the curtain body 1 is pulled out, the coil spring is stretched or twisted, storing energy; when the curtain body 1 is released, the coil spring releases energy, driving the roller to rotate in the opposite direction, thereby winding the curtain body 1 back. The coil spring can be made of flat steel strip wound together, and its elastic coefficient and number of coils need to be precisely designed according to the weight, length, and required winding force of the curtain body 1.

[0085] To ensure a reliable mechanical connection between the curtain body 1 and the roller, so that the rotation of the roller can effectively drive the curtain body 1 to wind or unwind, the fixed end of the curtain body 1 is fixedly connected to the roller. This fixed connection can be achieved in various ways, such as by opening a slot on the outer circumference of the roller, inserting the fixed end of the curtain body 1 into it, and fixing it with clips, adhesives, or stitching; or by setting a fixing clamp on the roller to clamp the curtain body 1. The curtain body 1 is wound around the outer circumference of the roller, ensuring that the curtain body 1 can be neatly and tightly wound on the roller when retracted, avoiding loosening or jamming.

[0086] A coil spring is housed within the inner cavity of the roller. One end of the spring is fixedly connected to the roller, and the other end is fixedly connected to the housing. This is the core mechanism for achieving automatic winding. The inner cavity of the roller is typically hollow, allowing the coil spring to be pre-installed within it. One end of the spring can be securely connected to the inner wall or internal structure of the roller through welding, riveting, or snap-fitting, ensuring that the roller rotates and drives the spring to twist along with it. The other end of the spring is similarly fixed to the inner wall or internal support of the housing, serving as a fixed support point for the spring. This allows the spring to effectively store and release elastic potential energy when the roller rotates, thereby achieving the automatic winding function of the curtain body 1.

[0087] Through the above technical solution, the automatic winding mechanism 2 is specifically embodied as a combination of a roller and a coil spring, with the coil spring cleverly placed inside the inner cavity of the roller, achieving a compact structure for the automatic winding mechanism 2. When the curtain body 1 is pulled out, the roller rotates and drives the coil spring to twist, thereby storing elastic potential energy in the coil spring. When the curtain body 1 is released, the coil spring releases the stored energy, driving the roller to rotate in the opposite direction, thus automatically winding the curtain body 1 back into the housing. This design not only provides a reliable automatic winding function, but also effectively saves space because the coil spring is integrated inside the roller, making the entire blind curtain device more integrated and aesthetically pleasing, and improving the user experience.

[0088] This application further proposes that the automatic winding mechanism 2 also includes a locking mechanism and an unlocking component; the locking mechanism cooperates with the winding shaft to lock the circumferential rotation of the winding shaft; the unlocking component cooperates with the locking mechanism to release the locking mechanism from locking the winding shaft.

[0089] The locking mechanism is used to prevent the circumferential rotation of the roller, keeping the curtain body 1 in the unfolded state. The locking mechanism can be implemented in various forms. For example, a ratchet and pawl structure can be used, where the ratchet is fixed to the roller, and the pawl engages with the teeth of the ratchet, thereby preventing the roller from rotating in the opposite direction under the action of the coil spring. When locking is required, the pawl engages with the ratchet under the action of the spring or gravity; when unlocking is required, the pawl is lifted by external force and disengages from the ratchet. Another implementation is a friction locking mechanism, which prevents the roller from rotating by increasing its frictional resistance, for example, by pressing a brake pad or brake block to hold the roller or a component coaxial with the roller. A pin-type locking mechanism can also be used, where a pin is inserted into a hole on the roller or a component linked to the roller to lock it.

[0090] The unlocking element works in conjunction with the locking mechanism to release the locking mechanism from the reel. The unlocking element should be designed for ease of user operation. For example, when the locking mechanism uses a ratchet and pawl structure, the unlocking element could be a button, a pull cord, or a lever that, through a mechanical linkage, lifts the pawl, disengaging it from the ratchet's engagement.

[0091] When the unlocking mechanism is activated, the locking state of the locking mechanism is released, allowing the roller to rotate freely, thus enabling the curtain body 1 to automatically retract under the action of the coil spring. The unlocking mechanism is located on the outside of the housing or in an easily accessible position for user operation at any time.

[0092] By incorporating a locking mechanism and an unlocking element into the automatic retraction mechanism 2, the curtain body 1 can be stably maintained in the unfolded state after being pulled out and unfolded to the desired position, preventing automatic retraction due to the spring force. When it is necessary to retract the curtain body 1, the user only needs to operate the unlocking element to release the lock, allowing the curtain body 1 to smoothly retract back into the housing under the drive of the spring. This design effectively improves the ease of use and functional flexibility of the blind, ensuring reliability in different usage scenarios.

[0093] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 This application further proposes a method for using the cargo cover 3 in the front trunk of a vehicle, including the following steps:

[0094] Pull out and unfold the curtain body 1, cover the opening area of ​​the front trunk 3 with the curtain body 1, and hook the first hook and the second hook to the side wall hanging points on both sides of the front trunk 3 respectively; or, pull out and unfold the curtain body 1, spread the curtain body 1 on the outer surface area of ​​the front bumper 5, and hook the first hook and the second hook to the same horizontal bar of the grille of the front bumper 5 respectively.

[0095] By designing the curtain body 1 as a flexible and rollable structure, and using hook components to selectively attach it to the first or second attachment position, the traditional storage curtain is limited to only covering the boundary of the storage space opening. This allows the curtain body 1 to actively extend to the outer surface area of ​​the front bumper 5 to form a physical isolation layer, directly blocking the contact path between the user's clothing and the dirt on the bumper surface.

[0096] Specifically, when the user needs to operate in the front trunk 3, the hook assembly is attached to the same horizontal bar of the front bumper 5 grille. The curtain body 1 is then deployed as a protective layer covering the outer surface area of ​​the front bumper 5, extending its effective range to easily soiled areas on the exterior of the vehicle. When only items need to be covered, the hook assembly is attached to the side wall hooks on both sides of the front trunk 3, so that the curtain body 1 covers the opening area of ​​the front trunk 3. When it is necessary to retract the curtain body 1, the user only needs to remove the first hook and the second hook from their current attachment positions. The curtain body 1 is then automatically retracted and housed inside the housing by the automatic retraction mechanism 2.

[0097] The above technical solution enables dynamic switching between dual functional modes: in the mode covering the opening area of ​​the front trunk 3, it effectively conceals items inside to enhance aesthetics and privacy; in the mode extending to the outer surface area of ​​the front bumper 5, it provides users with a direct physical barrier, preventing clothing from contacting dust and oil stains on the bumper surface. Compared to the traditional approach of indirectly reducing the probability of contact by shortening operation time, this solution extends the functional boundary of the curtain body 1 from inside the storage space to the external structure of the vehicle, eliminating the risk of clothing contamination and improving the user's experience when retrieving items from the front trunk 3.

[0098] This application provides a vehicle. The vehicle includes a body, a front trunk 3 and a front bumper 5 at the front of the body, a first hook structure on the side wall of the front trunk 3, and a second hook structure at the grille of the front bumper 5; and a cargo cover for the aforementioned vehicle's front trunk 3, the cargo cover being installed on the inner front part of the front trunk 3; the hook assembly of the cargo cover can be selectively hooked to the first hook structure or the second hook structure.

[0099] In its implementation, the cargo cover's main body 1 is a flexible, rollable structure with hook assemblies at both ends. When a user needs to cover items inside the front trunk 3, the hook assemblies can be attached to the first attachment structure, allowing the main body 1 to cover the opening area of ​​the front trunk 3, effectively blocking external views and improving the cleanliness and privacy of the vehicle interior. When a user needs to retrieve or place items from the front trunk 3, the hook assemblies can be attached to the second attachment structure, allowing the main body 1 to spread out over the outer surface of the front bumper 5, forming a continuous physical barrier layer that directly prevents clothing from contacting dirt on the bumper surface.

[0100] The above technical solution breaks through the design limitations of traditional cargo covers, which are limited to covering the opening of the storage space. It innovatively extends the function of the curtain body 1 to protect the surface of the front bumper 5. Because the hook assembly can be selectively attached to different positions, the curtain body 1 can flexibly switch between covering items and protecting the bumper, effectively preventing direct contact between the user's clothing and dirt on the bumper. This significantly improves the convenience of operating the front trunk 3 and the user experience. Through structural optimization, it directly solves the problem of clothing contamination caused by dirt on the bumper, while also meeting the need for item concealment, forming a complete technical system.

The vehicle includes a body, a front trunk 3 and a front bumper 5 at the front of the body, a first hook structure on the side wall of the front trunk 3, and a second hook structure at the grille of the front bumper 5; and a cargo cover for the aforementioned vehicle's front trunk 3, the cargo cover being installed on the inner front part of the front trunk 3; the hook assembly of the cargo cover can be selectively hooked to the first hook structure or the second hook structure.

[0102] In its implementation, the cargo cover's main body 1 is a flexible, rollable structure with hook assemblies at both ends.
