Technical Field

[0001] The utility model relates to the technical field of sealing mechanisms, in particular to a sealing mechanism for a luggage case assembly. Background Art

[0002] Automobile sealing strips have the function of filling various intervals and gaps between the components of the car body. They have the functions of shock absorption, waterproofing, dustproofing, sound insulation, decoration, etc., which can improve the comfort of driving experience and protect the car body. In order to improve the sealing performance of the car trunk, corresponding sealing strips are usually fixed on the car trunk.

[0003] For example, a car trunk sealing strip structure with publication number CN204726346U includes a U-shaped mounting structure and a hollow foam tube structure; the hollow foam tube structure is provided with a plurality of exhaust holes on the side close to the car body; a bottom external LIP and a bottom sponge water-stopping structure are provided on one side of the U-shaped mounting structure, and a middle internal LIP is provided on the other side; a sponge water-stopping part is provided inside the U-shaped mounting structure; two layers of water-retaining LIPs that match each other are also provided inside the U-shaped mounting structure, and the inclination direction is the same as the sheet metal insertion direction; the metal skeleton embedded in the U-shaped mounting structure is evenly and independently distributed in the trunk sealing strip; the sealing strip end joint position is a hollow tube through structure.

[0004] The above-mentioned prior art has the following technical problems: the existing sealing strip structure performs buffering through the deformation of the hollow foam tube when it is under pressure during use, but the buffering method of the hollow foam tube is relatively simple and can only play a buffering effect once. When the buffering effect is not good, when the user closes the trunk lid with force, the trunk lid is easily subjected to a greater degree of impact. At the same time, the sealing strip structure is an integrated molding structure during use. When a certain part of the sealing strip is damaged, the entire sealing strip needs to be replaced, which easily causes a waste of resources.

[0005] Therefore, we propose a sealing mechanism for a luggage case assembly to solve the above-mentioned problems. Utility Model Content

When the cushioning effect is not good, when the user closes the luggage case lid with force, the luggage case lid is easily impacted to a greater extent. At the same time, the sealing strip structure is an integrated structure during use. When a certain part of the sealing strip is damaged, the entire sealing strip needs to be replaced, which easily causes the problem of waste of resources.

[0007] To achieve the above object, the utility model provides the following technical solution: a sealing mechanism for a luggage case assembly, comprising a sealing main card strip, the upper end of which is fixedly connected to a positioning hollow rubber hose, and a connecting groove is provided in the middle of the positioning hollow rubber hose, and a plurality of built-in sealing side strips are fixedly connected to the interior of the sealing main card strip;

[0011] Preferably, the secondary buffer component includes a buffer tube and an auxiliary spring, and the buffer tube is fixed inside the positioning hollow rubber hose, and the auxiliary spring is fixedly connected to the inner middle part of the buffer tube.

[0012] By adopting the above technical solution, the auxiliary spring can be elastically deformed when under pressure, and the elastic deformation of the auxiliary spring can play a buffering role.

[0013] Preferably, the longitudinal section of the buffer conduit is set to an elliptical structure, and the buffer conduit is bonded and fixed to the inner wall of the connecting groove in the middle of the positioning hollow rubber hose, and the buffer conduit is set to an elastic rubber material.

[0031] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] Example 1: Please refer to Figure 1-Figure 5 The existing sealing strip structure is used to cushion the deformation of the hollow foam tube when it is under pressure, but the cushioning method of the hollow foam tube is relatively simple and can only play a one-time cushioning effect. When the cushioning effect is not good, when the user closes the trunk lid with force, the trunk lid is easily subjected to a greater degree of impact. In order to solve this technical problem, this embodiment discloses the following technical content;

[0033] A sealing mechanism for a luggage case assembly includes a sealing main card strip 1, a positioning hollow rubber hose 2 is fixedly connected to the upper end of the sealing main card strip 1, and a connecting groove 3 is opened in the middle of the positioning hollow rubber hose 2, and a plurality of built-in sealing side strips 4 are fixedly connected to the interior of the sealing main card strip 1;

[0034] A secondary buffer component is provided in the connecting groove 3 provided inside the positioning hollow hose 2, and the deformation buffering effect of the positioning hollow hose 2 under pressure is improved by the secondary buffer component; the secondary buffer component includes a buffer tube 5 and an auxiliary spring 6, and the buffer tube 5 is fixed inside the positioning hollow hose 2, and the middle part of the inner side of the buffer tube 5 is fixedly connected with the auxiliary spring 6. The longitudinal section of the buffer tube 5 is set to an elliptical structure, and the buffer tube 5 is bonded and fixed to the inner wall of the connecting groove 3 in the middle of the positioning hollow hose 2, and the buffer tube 5 is set to an elastic rubber material. The middle part of the buffer tube 5 is set to a hollow structure, and a plurality of auxiliary springs 6 are evenly distributed inside the buffer tube 5 at equal intervals.

[0035] When the trunk lid of the automobile is closed, the positioning hollow hose 2 at the upper end of the sealing main card strip 1 is pressurized. After the positioning hollow hose 2 is pressurized, the buffer tube 5 inside undergoes elastic deformation. The elastic deformation of the buffer tube 5 can play a buffering role. A plurality of auxiliary springs 6 are evenly distributed inside the buffer tube 5. After the buffer tube 5 is pressurized, the auxiliary spring 6 inside also undergoes elastic deformation. The elastic deformation of the auxiliary spring 6 can further improve the overall elastic buffering effect, thereby avoiding the case where the buffering effect is poor and the trunk lid is susceptible to a greater degree of impact when the user closes the trunk lid with force.

[0036] Embodiment 2: The technical content disclosed in this embodiment is a further improvement on the above embodiment 1. The sealing strip structure is an integrated structure when in use. When a certain part of the sealing strip is damaged, the entire sealing strip needs to be replaced, which easily causes a waste of resources. In order to further solve this technical problem, this embodiment discloses the following technical content, such as Figure 1 , Figure 2 and Figure 5 As shown;

[0037] A docking guide strip 7 is fixedly connected to one side of the main sealing strip 1, and the edge of the docking guide strip 7 is arched outward to form a protrusion 8, and a first accommodating groove 9 is provided on the other side of the main sealing strip 1, and a second accommodating groove 10 is provided on the side of the first accommodating groove 9, and the first accommodating groove 9 and the second accommodating groove 10 are used to accommodate the docking guide strip 7 and the protrusion 8. There are multiple docking guide strips 7 and protrusions 8 evenly distributed on the main sealing strip 1, and the docking guide strips 7 and the protrusions 8 correspond to the first accommodating groove 9 and the second accommodating groove 10 one by one.

[0038] The main sealing card strip 1 adopts a segmented design, and adjacent main sealing card strips 1 are fixed by gluing. When a certain part of the main sealing card strip 1 is damaged, the section of the main sealing card strip 1 can be replaced independently, avoiding the main sealing card strip 1 adopting an integrated design. When a certain part is damaged, the main sealing card strip 1 needs to be replaced as a whole. The docking guide strip 7 and the protrusion 8 on the side of one main sealing card strip 1 are correspondingly glued to the inside of the first accommodating groove 9 and the second accommodating groove 10 on the side of another main sealing card strip 1, thereby further improving the contact area between adjacent main sealing card strips 1 and increasing the connection strength between adjacent main sealing card strips 1.
