Description

Technical Field

[0001] This utility model relates to the field of automotive travel products technology, and in particular to a waterproof roof luggage bag. Background Technology

[0002] In outdoor driving and travel scenarios, roof bags are core equipment for expanding the vehicle's cargo space. They are exposed to rain and humid environments for a long time, so there is a rigid requirement for the waterproof and sealing performance of the bag.

[0003] The closure of existing roof bags mainly relies on zipper components. However, traditional zippers use a spliced ​​structure for the teeth, and there are naturally tiny gaps between adjacent teeth. When the bag is soaked or sprayed with rainwater, rainwater will gradually seep into the bag along the gaps between the teeth, causing the clothes, electronic devices, outdoor tools and other items to become damp and moldy, or even suffer damage such as electrical short circuits and mechanical corrosion, seriously affecting the practicality and safety of the bag.

[0004] In existing technologies, a common solution is to sew a waterproof lining onto the outside of the zipper. This involves covering the zipper area with a piece of waterproof fabric in an attempt to prevent rainwater from directly contacting the zipper. However, while the lining can cover the zipper, the fabric's adhesion to the bag's surface relies on its own weight or is simply a matter of adhesion, failing to create a tight seal. Bumps during vehicle movement can cause the lining to shift slightly, creating gaps at the edges. Rainwater can then directly contact the zipper through these gaps. Since the gaps between the zipper teeth themselves already pose a risk of water seepage, rainwater ultimately seeps into the bag along these gaps. Utility Model Content

[0005] This utility model addresses the shortcomings of existing technologies by providing a waterproof roof luggage bag, thus solving the problems of poor waterproof performance at the zipper of existing roof luggage bags, which easily leads to water leakage, and the inconvenience of zipper operation.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A waterproof roof bag includes a bag body and a zipper mounted on the bag body. The zipper has a waterproof sealing part for preventing water seepage to form an airtight waterproof zipper. The end of the waterproof sealing part has a sealing reinforcement structure for improving the water-proof sealing performance of the zipper pull and limiting and buffering the movement of the zipper pull. The bag body also has an auxiliary pulling element for using as a force point to assist in pulling the zipper.

[0007] Preferably, the sealing enhancement structure includes a sealing plate, which is disposed at the end of the waterproof sealing part and cooperates with the zipper pull to form a seal. By providing a sealing plate that cooperates with the zipper pull, the basic sealing performance at the zipper pull is directly enhanced, and the gap between the zipper pull and the waterproof sealing part is filled.

[0008] Preferably, the sealing plate is provided with a clamping groove. The sealing plate can deform itself to fit the clamping groove into the inside of the zipper head, forming a sealed fit. The clamping groove, combined with the self-deformation capability of the sealing plate, can adaptively fit the internal contour of the zipper head to form a dynamic seal, avoiding water leakage caused by poor fit and significantly improving the reliability of the seal.

[0009] Preferably, the sealing plate has limiting ends at both ends, which form limiting resistance to the zipper pull, effectively preventing the zipper pull from sliding due to external factors such as vehicle bumps, preventing seal failure caused by accidental opening of the zipper, and maintaining the stability of the water-proof state. Preferably, the limiting end is provided with a guide groove, which is integrated with the sealing plate to ensure that the pull head can pass through the limiting end after applying a preset force. The guide groove guides the limiting end to deform under force, ensuring the limiting resistance while ensuring that the pull head can pass smoothly after applying a preset force, avoiding pulling jamming caused by excessive limiting.

[0010] Preferably, the sealing plate is provided with a blocking end to prevent the pull head from directly impacting the waterproof seal. The blocking end blocks the pull head when it is in position and absorbs the impact force itself, thus preventing the pull head from directly impacting the waterproof seal and reducing damage to the waterproof seal caused by long-term impact, thereby extending its service life.

[0011] Preferably, the sealing sheet is made of an elastic material and is integrally connected to the end of the waterproof sealing part. The elastic material ensures that the sealing sheet has the ability to deform and seal, and the integral connection with the waterproof sealing part enhances the structural integrity and waterproof continuity.

[0012] Preferably, the auxiliary pulling component includes a connecting part, a fixing part, and a gripping part. The connecting part is connected to the bag body, and the gripping part is disposed on the connecting part through the fixing part. The gripping part constitutes the force point. The gripping part can be designed into various shapes such as ring or belt according to actual needs to facilitate the user's grip and force application. For example, if designed as a ring, it can be made of metal or high-strength plastic material to ensure its strength and durability. At the same time, it ensures that the gripping part can move flexibly relative to the connecting part to adapt to different pulling angles.

[0013] Preferably, the auxiliary pull member is located behind the zipper. The connecting part can be fixedly connected to the bag body by riveting, welding or bonding, and the connection position is ensured to be behind the zipper so that the force points of the grip and the zipper pull are on the same straight line. The length and shape of the connecting part are designed according to the position of the bag body and the zipper to ensure that the auxiliary pull member can play an effective role. The connecting part is made of flexible material, and the grip can move relative to the connecting part to adapt to the pulling operation. The design of the connecting part as a flexible material can buffer the force when the grip is subjected to force, reduce the direct pulling on the bag body, and reduce the risk of damage to the bag body due to frequent force.

[0014] Preferably, the zipper has two pull tabs. When the zipper is in a closed and sealed state, the two pull tabs are located at both ends of the zipper and cooperate with the waterproof sealing parts at the corresponding ends.

[0015] Compared with the prior art, the present invention has the following beneficial effects: This utility model uses an airtight waterproof zipper. Its waterproof sealing part ensures the water-proof performance of the luggage bag and avoids the items from getting wet and damaged. The sealing plate and the zipper head cooperate to enhance the basic sealing performance. The clamping groove adapts to the inside of the zipper head by the deformation of the sealing plate, eliminating gaps and preventing water leakage. The limiting end prevents the zipper head from sliding due to bumps and maintains the stability of the seal. Its guide groove ensures that the zipper head can pass smoothly after applying force, balancing anti-slip and easy operation. The blocking end can prevent the zipper head from directly impacting the waterproof sealing part, reducing damage and extending the service life. Furthermore, the auxiliary pull component provides a stable point of force, eliminating the need for users to directly pull the bag. Pulling the zipper pull makes it easier, solving the problem of excessive pulling effort in existing products. The auxiliary pull component is located behind the corresponding zipper, ensuring that the force points are on the same straight line, reducing force loss and pulling resistance. The connecting part is made of flexible material, which cushions the force and reduces the risk of damage to the bag. Attached Figure Description

[0019] The present invention will now be described in further detail with reference to the accompanying drawings.

[0020] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious modifications will be apparent to those skilled in the art. The basic principles of the present invention defined in the following description can be used in other embodiments, modifications, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the present invention.

[0021] Those skilled in the art should understand that in the disclosure of this utility model, the terms "longitudinal", "lateral", "up", "down", "left", "right", "front", "rear", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or position based on the orientation or positional relationship shown in the accompanying drawings. They are only for the purpose of simplifying the description of this utility model and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limitations on this utility model.

[0022] It is understood that the term "a" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element can be one, while in another embodiment, the number of the element can be multiple, and the term "a" should not be understood as a limitation on the number.

[0023] Example: Please see Figure 1-5A waterproof roof bag includes a bag body 1 and a zipper 2 mounted on the bag body 1. The zipper 2 has a waterproof sealing part 21 for waterproofing, forming an airtight waterproof zipper. The zipper 2 can be any existing airtight waterproof zipper, and the waterproof sealing part 21 is a waterproof component in existing airtight waterproof zippers. The airtight waterproof zipper ensures the bag's waterproof performance. To achieve this waterproof performance, the waterproof sealing part 21 (such as a sealing strip) has a high degree of fit with the zipper teeth, tightly filling the gaps between the teeth when closed. This structural feature results in greater resistance when the zipper pull is pulled, therefore the bag body 1 also... An auxiliary puller 3 is provided to assist in pulling the zipper 2 as a point of force. The auxiliary puller 3 makes it easier for the user to pull the zipper 2. The zipper 2 has two zipper heads. When the zipper 2 is in a closed and sealed state, the two zipper heads are located at the two ends of the zipper 2 and cooperate with the waterproof sealing part 21 at the corresponding ends. When taking out items, one of the zipper heads can be pulled alone (the other zipper head remains in the closed position), opening only a part of the zipper 2 without fully opening the entire zipper 2, reducing the exposed area of ​​the items in the bag. The unopened section remains sealed, and both zipper heads can achieve the closure and sealing of the zipper 2 when pulled in opposite directions.

[0024] The sealing reinforcement structure includes a sealing piece 22, which is located at the end of the waterproof sealing part 21 and cooperates with the zipper pull on the zipper 2 to form a seal. The sealing piece 22 is made of a material with good elastic deformation ability and is integrated with the end of the waterproof sealing part 21 to ensure the integrity of the structure and the continuity of waterproofing.

[0025] The closure plate 22 is provided with a clamping groove 23. The closure plate 22 can deform itself to make the clamping groove 23 fit against the inside of the zipper head, forming a sealed fit. The clamping groove 23 is opened in the middle of the closure plate 22, and its outline matches the inner shape of the zipper head (including the curved surface and edges of the zipper head). When the zipper head moves to the closure plate 22, the zipper head squeezes the inner wall of the clamping groove 23. The closure plate 22 deforms itself to make the clamping groove 23 fit tightly against all contact surfaces of the zipper head, eliminating gaps. Even if the zipper head wears or has dimensional errors due to long-term use, the deformation ability of the closure plate 22 can still ensure a tight seal, effectively solving the problem of water seepage at the zipper head.

[0026] The sealing plate 22 has limiting ends 24 at both ends, which form a limiting resistance to the slider. The limiting ends 24 are symmetrically arranged at both ends of the sealing plate 22, and their height is higher than the surface part of the clamping groove 23. Through their own elasticity, they form a preset resistance to the slider (the magnitude of the resistance can be adjusted by adjusting the thickness and hardness of the limiting ends 24). When the vehicle is bumpy, this resistance is sufficient to prevent the slider from sliding on its own; when the user actively pulls the slider, the force applied by the slider can overcome the resistance. The limiting end 24 is provided with a guide groove 25, which is integrated with the sealing plate 22. The guide groove 25 ensures that the pull head can pass smoothly, avoids operation jamming due to excessive resistance, and ensures that the pull head can pass through the limiting end 24 after applying a preset force.

[0027] The sealing plate 22 is provided with a blocking end 26 to block the zipper pull and prevent it from directly impacting the waterproof seal 21. The blocking end 26 protrudes from the sealing plate 22. When the zipper pull is pulled to the end of the zipper 2, the zipper pull first contacts the blocking end 26. The elastic deformation of the sealing plate 22 absorbs part of the impact force, which significantly reduces the force transmitted to the waterproof seal 21 and can prevent the waterproof seal 21 from cracking or failing due to long-term impact.

[0028] The auxiliary pulling component 3 includes a connecting part 31, a fixing part 32, and a gripping part 33. The connecting part 31 is connected to the bag body 1, and the gripping part 33 is provided on the connecting part 31 through the fixing part 32. The gripping part 33 constitutes the force point. The gripping part 33 can be designed into various shapes such as ring or belt according to actual needs to facilitate the user's grip and force application. For example, if it is designed as a ring, it can be made of metal or high-strength plastic material to ensure its strength and durability. At the same time, it ensures that the gripping part 33 can move flexibly relative to the connecting part 31 to adapt to different pulling angles.

[0029] The auxiliary pull part 3 is located behind the zipper 2. The connecting part 31 can be fixedly connected to the bag body 1 by riveting, welding or bonding, and the connection position is ensured to be behind the zipper 2, so that the grip part 33 and the force point of the zipper 2 are on the same straight line. The length and shape of the connecting part 31 are designed according to the position of the bag body 1 and the zipper 2 to ensure that the auxiliary pull part 3 can play an effective role.

[0030] The connecting part 31 is made of flexible material, and the gripping part 33 can move relative to the connecting part 31 to adapt to the pulling operation. The design of the connecting part 31 as a flexible material can buffer the force when the gripping part 33 is subjected to force, reduce the direct pulling on the package body 1, and reduce the risk of damage to the package body 1 due to frequent force.

[0031] The auxiliary pull part 3 provides a stable point of force for users when pulling the airtight and waterproof zipper with high resistance. Users no longer need to pull the bag body 1 directly. Instead, they can hold the grip part 33 of the auxiliary pull part 3 and pull the zipper 2 in conjunction with it. The operation is easier and more comfortable, effectively solving the problem of the difficulty in pulling existing products.

[0032] When it is necessary to open or close the airtight and waterproof zipper, the user holds the grip part 33 of the auxiliary pull part 3 with one hand. Since the grip part 33 is connected to the connecting part 31 through the fixing part 32, and the connecting part 31 is connected to the bag body 1, the grip part 33 serves as a stable force point, providing the user with a reliable point of force application. The user pulls the zipper pull 2 ​​with the other hand, and the two hands work together to complete the pulling operation of the zipper 2. Since the auxiliary pull part 3 is located behind the zipper 2, during the pulling process, the zipper pull 2 ​​and the force application point of the auxiliary pull part 3 (i.e., the grip part 33) are on the same straight line, and the force applied by both hands can be transmitted in a straight line, avoiding... This design eliminates force loss caused by lateral force due to deviation of the force application point, allowing the force applied by the user to act more efficiently on the zipper pull 2, significantly reducing pulling resistance and making it easier for the user to pull the zipper pull 2. The connecting part 31 is made of flexible material, which can buffer the force to a certain extent when the grip part 33 is subjected to force, reducing direct pulling on the bag body 1 and thus reducing the risk of damage to the bag body 1. At the same time, the grip part 33 can move relative to the connecting part 31, allowing the user to flexibly adjust the direction of the grip part 33 according to their own operating habits and the pulling direction of the zipper 2 during the pulling process, further improving the convenience of operation.

The purpose of the present invention has been fully and effectively achieved. The functions and structural principles of the present invention have been shown and explained in the embodiments.
