Abstract
Description
Technical Field
[0001] This utility model relates to the field of automotive parts technology, and more specifically, to a cooperative structure between an automotive cargo net and a vehicle roof. Background Technology
[0002] In the daily use of cars, the storage and securing of in-car items has always been a key concern for users. Car roof nets, as a commonly used in-car storage device, provide users with additional storage space, making it convenient to place lightweight items such as clothes and bags, thereby improving the utilization of interior space and meeting diverse travel needs.
[0003] Currently, most cargo nets used on car roofs rely on hooks on the vehicle body for installation and fixation. These hooks are typically hinged to the roof in a protruding form. This hinged structure allows the hooks to accommodate the pulling angle of the cargo net to some extent, enabling convenient installation and basic fixation during initial use. However, with long-term use of the vehicle, this hook structure has gradually revealed significant shortcomings.
[0004] During driving, a car is inevitably subjected to dynamic loads such as road bumps, acceleration, and deceleration. The cargo net and its load will also sway and shift, exerting repeated pulling and torsional forces on the hooks. Since the hooks are hinged to the roof, the hinge points are prone to wear and loosening under these complex external forces over time. Furthermore, the protruding design of the hooks makes them more susceptible to collisions with passengers or items inside the vehicle, further exacerbating damage. Once the hooks are damaged, the cargo net will not be properly secured, affecting its functionality, and items may fall during driving, potentially threatening the safety of occupants. Utility Model Content
[0005] The purpose of this application is to provide a matching structure between a car cargo net and the car roof, which has the advantages of improving the fixing reliability of the cargo net and enhancing the safety of use.
[0006] This application provides a matching structure between a car cargo net and a car roof, comprising: a hook assembly including a hook body for connecting the car cargo net, the hook body having a hook portion at its end; and a bracket assembly including a bracket body for connecting the car roof, the bracket body having a large hook hole and a small hook hole that communicate with each other, the large hook hole for the hook portion to pass through, and the bracket body corresponding to the small hook hole abutting against the hook portion; the hook portion passes through the large hook hole into the small hook hole and engages with the small hook hole, thereby connecting the car cargo net to the car roof.
[0007] Compared with the prior art, the matching structure of the car cargo net and the car roof proposed in this application has the following advantages: by passing the hook part at the end of the hook body through the large hook hole and forming a surface contact with the bracket body corresponding to the small hook hole to prevent it from falling out, the cargo net and the car roof can be detachably and fixedly connected, avoiding the problem of wear and loosening under long-term dynamic load, and improving the fixing reliability and use safety.
[0008] In one possible implementation, the large hook hole and the small hook hole are connected by a guide groove, which has an inverted U-shaped structure. Compared with the prior art, the inverted U-shaped transition structure of the guide groove provides a clear movement path for the hook body, ensuring the stability of the connection.
[0009] In one possible implementation, the outer diameter of the hook body is smaller than the width of the guide groove, and the hook portion is an anti-detachment flange. The diameter of the anti-detachment flange is smaller than the diameter of the large hook hole but larger than the diameter of the small hook hole. Compared with the prior art, the size design of the anti-detachment flange achieves a one-way locking function, that is, the hook portion can be easily pushed into the large hook hole but cannot be dislodged from the small hook hole, thus balancing installation convenience and anti-detachment reliability.
[0010] In one possible implementation, the bracket body is fixedly connected to the back of the vehicle roof. The vehicle roof has a through hole for the hook assembly to pass through, the through hole corresponding to the position of the bracket assembly. The through hole allows the hook assembly to pass through and extend to the hook hole area of the bracket body. Compared with the prior art, the back-mounted design of the bracket body hides the hook connection point inside the roof, avoiding interference with the interior space and accidental scratches caused by exposed structures; the precise alignment of the through hole and the hook hole area ensures the guiding accuracy of the hook movement.
[0011] In one possible implementation, the bracket body is detachably connected to the vehicle roof via hook-and-loop fasteners. Compared to existing technologies, the hook-and-loop fastener connection eliminates the need for drilling holes in the roof, allowing for quick assembly and disassembly of the bracket assembly, facilitating future maintenance or replacement.
[0012] In one possible implementation, a silicone cover is provided at the through-hole, and the silicone cover has an opening that matches the movement path of the hook body. Compared with the prior art, the silicone cover covering the through-hole not only protects the internal structure of the vehicle roof from external pollution, but also guides the movement of the hook body through the opening, preventing dust from entering the hook hole area; the elastic cushioning effect of the silicone material can also absorb the vibration and impact during vehicle operation, reduce wear between metal parts, and extend service life.
[0013] In one possible implementation, the silicone face mask is mounted in a through-hole in the vehicle roof via a face mask mounting bracket. Compared to existing technologies, the face mask mounting bracket ensures a secure connection between the silicone face mask and the edge of the through-hole, preventing the face mask from shifting or falling off during frequent use and extending its service life.
[0014] In one possible implementation, the support assembly further includes a reinforcing plate fixedly connected to the back of the support body, with the hook abutting against the reinforcing plate to prevent it from protruding from the support assembly. Compared to the prior art, the reinforcing plate increases the rigidity of the support body while preventing the hook from protruding from the small hook hole. Attached Figure Description

Detailed Implementation
[0023] First, those skilled in the art should understand that these embodiments are merely used to explain the technical principles of the embodiments of this application and are not intended to limit the scope of protection of the embodiments of this application. Those skilled in the art can make adjustments as needed to adapt to specific application scenarios.
[0024] In the description of the embodiments of this application, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in the embodiments of this application based on the specific circumstances.
[0025] In the embodiments of this application, unless otherwise expressly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.
[0026] In existing technologies, the installation of car roof nets primarily relies on articulated hook structures. These hooks, subjected to long-term dynamic loads, are prone to loosening and wear, and their protruding design increases the risk of collision with items inside the vehicle. With increased use, the articulated joints gradually fail, leading to a greater risk of the net detaching and compromising driving safety.
[0027] To address the aforementioned issues, the inventors discovered that the insufficient stability of the hinged structure under dynamic loads was the core defect. Analysis revealed that while a fixed connection could prevent hinge wear, it was necessary to resolve the conflict between adjusting the installation angle and preventing detachment. Further consideration was given to incorporating concealed fixing points within the ceiling, which could eliminate the risk of external collisions while ensuring a reliable connection. Ultimately, a segmented locking scheme using hook holes was developed, employing different hole diameters to achieve both installation guidance and anti-detachment fixation.
[0028] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments.
[0029] See Figures 1 to 6This application discloses a cooperative structure between a car cargo net and a vehicle roof, including: a hook assembly 1 and a bracket assembly 2; the hook assembly 1 includes a hook body 11 for connecting the car cargo net 10, and a hook portion 12 is provided at the end of the hook body 11; the bracket assembly 2 includes a bracket body 21 for connecting the vehicle roof 20, and the bracket body 21 has a large hook hole 211 and a small hook hole 212 that are interconnected. The large hook hole 211 is used for the hook portion 12 to pass through, and the bracket body 21 corresponding to the small hook hole 212 abuts against the hook portion 12; the hook portion 12 passes through the large hook hole 211 and enters the small hook hole 212, and hooks and cooperates with the small hook hole 212, so that the car cargo net 10 is connected to the vehicle roof 20. The vehicle roof 20 includes a roof body 201 and a roof bracket 202, the roof bracket 202 is fixedly connected to the back of the roof body 201, and the bracket body 21 is connected to the back of the roof bracket 202.
[0030] Among them, hook assembly 1 refers to the connecting unit used to bear the tension of the load net, which can be made of metal stamping; bracket assembly 2 refers to the support unit fixed to the roof 20 of the vehicle body, which can be made of sheet metal stamping. Its large hook hole 211 has a diameter that allows the hook part 12 to pass through freely, and the small hook hole 212 has a diameter that is smaller than the maximum outer diameter of the hook part 12.
[0031] See also Figure 5 In this embodiment, the large hook hole 211 and the small hook hole 212 are connected by a guide groove 213, which has an inverted U-shaped structure. The guide groove 213 is a structural channel connecting the large hook hole 211 and the small hook hole 212; the inverted U-shaped structure means that the guide groove 213 has a downward-facing semi-circular arc shape with its opening 401 facing downwards. Specifically, when the operator inserts the hook 12 into the large hook hole 211, the guide groove 213 limits the movement path of the hook body 11, causing the hook 12 to move towards the small hook hole 212.
[0032] In this embodiment, the outer diameter of the hook body 11 is smaller than the width of the guide groove 213, and the hook portion 12 is an anti-detachment flange. The diameter of the anti-detachment flange is smaller than the diameter of the large hook hole 211 and larger than the diameter of the small hook hole 212. Specifically, the hook body 11 moves along an inverted U-shaped path under the constraint of the width of the guide groove 213. After entering through the large hook hole 211, the anti-detachment flange slides into the area of the small hook hole 212. Since the diameter of the anti-detachment flange is larger than the diameter of the small hook hole 212, it cannot detach in the opposite direction after being hooked, while its smaller diameter allows it to be inserted smoothly. This size matching relationship makes the hook stable under dynamic loads and avoids assembly difficulties caused by size errors.
[0033] See also Figure 3In this embodiment, the bracket body 21 is fixedly connected to the back of the vehicle roof 20. The vehicle roof 20 is provided with a through hole 30 for the hook assembly 1 to pass through. The through hole 30 corresponds to the position of the bracket assembly 2, and the through hole 30 allows the hook assembly 1 to pass through and extend to the hook hole area of the bracket body 21. Specifically, the bracket body 21 is installed on the back of the vehicle roof 20 by a fixed connection. The position of the through hole 30 on the roof surface forms a perpendicular projection relationship with the hook hole area of the bracket body 21. During installation, the hook assembly 1 passes through the through hole 30 and enters the hook hole area of the bracket body 21. The hook 12 slides from the large hook hole 211 into the small hook hole 212 through the guide groove 213 to complete the locking. The design of the through hole 30 allows the hook body 11 to move only along a preset path when passing through.
[0034] In this embodiment, the bracket body 21 is detachably connected to the vehicle roof 20 via a mushroom-shaped hook and loop fastener 3. The mushroom-shaped hook and loop fastener 3 is a mechanical connector composed of hook and loop surfaces that can be repeatedly bonded and separated. Specifically, it can be made of nylon injection-molded hook-shaped fibers combined with loop fibers. The hook and loop surfaces form a locking connection through pressing, and are separated by external force. This structure allows for quick assembly and disassembly of the bracket assembly 2 without damaging the vehicle roof 20, facilitating bracket maintenance or replacement. This connection method avoids the problem of drilling holes in the roof for traditional bolt fixing, and also eliminates gaps, preventing abnormal noise.
[0035] In this embodiment, a silicone mask 40 is provided at the through hole 30, and the silicone mask 40 has an opening 401 that matches the moving path of the hook body 11. The silicone mask 40 is a flexible protective structure covering the surface of the through hole 30. Specifically, it can be made by vulcanization molding of silicone material into a cover that fits tightly against the edge of the through hole 30. Its function is to prevent the internal structure of the vehicle body from being exposed and to prevent dust from entering. The opening 401 guides the hook body 11 to move in a predetermined direction. Specifically, the silicone mask 40 adapts to the insertion action of the hook body 11 through elastic deformation, and the outline of the opening 401 completely coincides with the movement trajectory of the hook body 11. When the hook body 11 passes through the through hole 30, the edge of the opening 401 of the silicone mask 40 elastically expands. After the hook body 11 fully enters the hook hole area of the bracket assembly 2, the opening 401 returns to its original shape to cover the outer wall of the hook body 11.
[0036] In this embodiment, the silicone face mask 40 is installed in the through hole 30 of the vehicle roof 20 via the face mask mounting base 50. The face mask mounting base 50 refers to the support structure used to support and fix the silicone face mask 40. Specifically, it can be an injection-molded plastic base, which is fixed to the edge of the through hole 30 by clips or screws to achieve a stable connection between the silicone face mask 40 and the vehicle roof 20.
[0037] In this embodiment, the bracket assembly 2 further includes a reinforcing plate 22, which is fixedly connected to the back of the bracket body 21. The hook 12 abuts against the reinforcing plate 22 to prevent the hook 12 from being pushed out of the bracket assembly 2. The reinforcing plate 22 is an auxiliary support structure connected to the bracket body 21. Specifically, it can be made of steel plate or engineering plastic and fixed to the back of the bracket body 21 by welding or bolting, to increase the load-bearing capacity of the bracket assembly 2 for the hook 12. Specifically, after the bracket body 21 is connected to the vehicle roof 20, the reinforcing plate 22 is fixed to its back to form a support surface. When the hook body 11 is subjected to dynamic loads causing the hook 12 to experience an outward pushing force, the reinforcing plate 22, through its rigid connection with the bracket body 21, transmits the pushing force to the vehicle roof 20 structure. Simultaneously, the contact surface between the hook 12 and the reinforcing plate 22 generates a counterforce, preventing the hook 12 from being pushed out.
