In the specification, the illustrative description of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner.

[0051] Next, the utility model will be described in detail through exemplary embodiments. However, it should be understood that the elements, structures and features in one embodiment can also be beneficially combined into other embodiments without further description.

[0052] The embodiment of the utility model provides a kind of luggage sealing structure, it is applied to straddle-type vehicle, by optimizing the cooperation structure between sealing strip and luggage, to facilitate the sealing stability of luggage is improved.

[0053] In the current technology, with the continuous development and advancement of motorcycle design, consumers' requirements for the performance of various positions on motorcycles are also constantly increasing. As the main storage space of a motorcycle, the luggage compartment is usually required to be large enough to hold daily necessities such as water and snacks, making travel more convenient for the rider. At the same time, when reversing, the presence of the luggage compartment prevents the motorcycle from directly contacting the ground, thus protecting both the motorcycle and the rider.

[0054] Existing motorcycle luggage compartments typically use a single-bubble sealing method. However, if the bubble tube experiences localized sealing issues such as tearing or aging, the entire sealing structure will fail, resulting in poor sealing stability.

[0055] In view of this, in order to overcome the shortcomings of the prior art, the luggage sealing structure of this embodiment combines... Figures 1 to 3 As shown, the overall design includes a box body 1 with an opening at one end, a flip-up lid 2 that snaps onto the opening of the box body 1, and a sealing strip 3 that seals the box body 1 and the lid 2 along the edge of the opening of the box body 1.

[0056] The sealing strip 3 has a first sealing part 301 and a second sealing part 302 extending along its own extension direction. On any cross-section of the sealing strip 3, the first sealing part 301 abuts against the box cover 2 along the first direction, and the second sealing part 302 abuts against the box cover 2 along the second direction, and the first direction and the second direction intersect.

[0057] Therefore, by providing a sealing strip 3 with a first sealing part 301 and a second sealing part 302, two seals can be formed between the box body 1 and the box cover 2. Even if one seal fails, the other seal can still maintain the seal between the box body 1 and the box cover 2, thereby improving the sealing stability.

[0058] Based on the above overview, please refer to... Figures 1 to 3 As shown, specifically, the lid 2 is connected to the body 1 by a hinge. When the lid 2 is fastened to the opening of the body 1, it covers the outside of the edge of the opening of the body 1. That is, after the lid 2 is fastened, the first sealing part 301 and the second sealing part 302 seal the gap between the body 1 and the lid 2 from two directions. Compared with the conventional single-bubble sealing form, not only is the sealing stability improved, but the sealing effect is also better.

[0059] The edge of the box cover 2 is provided with a first inner wall 201 and a second inner wall 202 connected with the first inner wall 201, the first inner wall 201 and the second inner wall 202 are arranged around the box cover 2, and the second inner wall 202 is inclined from the first inner wall 201 to the middle part of the box cover 2; the first sealing part 301 abuts against the first inner wall 201, and the second sealing part 302 abuts against the second inner wall 202. The first inner wall 201 and the second inner wall 202 are arranged at different angles, and the first sealing part 301 and the second sealing part 302 can improve the sealing effect. Of course, according to the structural design of the first inner wall 201 and the second inner wall 202, the included angle of the corresponding first direction and the second direction can also be changed in the path around the box cover 2, as long as the first direction and the second direction are kept intersecting.

[0060] For example, the first inner wall 201 is arranged around the opening edge of the box body 1, and after the first sealing part 301 contacts the first inner wall 201, the gap between the box body 1 and the box cover 2 is sealed in the first direction. After the box cover 2 is buckled to the box body 1, the opening edge of the box body 1 faces the second inner wall 202, the second sealing part 302 is located at the top of the sealing strip 3, and after the second sealing part 302 contacts the second inner wall 202, the gap between the box cover 2 and the box body 1 is sealed in the second direction.

[0061] Continuing to refer to Figures 1 to 3 As shown, in order to improve the sealing performance of the second sealing part 302, the second sealing part 302 has a second cavity 3021 arranged around the opening edge of the box body 1. By providing the second cavity 3021 on the second sealing part 302, the second sealing part 302 can more easily deform elastically to increase its contact area with the second inner wall 202 when it is pressed by the second inner wall 202, so as to fully fit the second inner wall 202 and improve the sealing effect.

[0062] Preferably, regarding the specific structure of the second sealing part 302, the second sealing part 302 of the embodiment includes a third elastic body 3022 and a fourth elastic body 3023 connected with each other, and the connection part of the third elastic body 3022 and the fourth elastic body 3023 abuts against the second inner wall 202. By arranging the third elastic body 3022 and the fourth elastic body 3023 and making the connection part of the third elastic body 3022 and the fourth elastic body 3023 abut against the second inner wall 202, the third elastic body 3022 and the fourth elastic body 3023 can simultaneously support the abutting part of the second inner wall 202, thereby reducing the collapse of the connection part of the third elastic body 3022 and the fourth elastic body 3023 when the opening of the box body 1 fluctuates greatly. The third elastic body 3022 and the fourth elastic body 3023 can be made of materials such as foamed ethylene-propylene-diene rubber, foamed polyurethane, and foamed polypropylene, and in the embodiment, the third elastic body 3022 and the fourth elastic body 3023 are made of foamed ethylene-propylene-diene rubber.

[0063] For example, referring to Figure 3 and in combination with Figure 4 The box 1 structure shown in the embodiment has two height mutations at positions a and b on the opening edge, and the mutation has a large slope. The conventional round bubble tube will have a more obvious collapse at the mutation position, and with the increase in the number of opening and closing of the box cover 2, the collapse of the round bubble tube will become more and more serious, causing the luggage box to be not tightly sealed, and possibly causing water leakage, which seriously affects the use quality. The cross section of the sealing strip 3 at the second sealing part 302 is roughly triangular, has good stability, and has strong anti-collapse ability, and can maintain structural stability after the number of opening and closing of the box cover 2 increases.

[0064] It should be noted that in some other implementable manners, the second sealing part 302 can also be provided in a tubular shape, that is, the second sealing part 302 is a pipe body arranged around the opening edge of the box 1 and connected in a closed manner at the head and tail. In this way, the second sealing part 302 can also have almost the same effect as the third elastic body 3022 and the fourth elastic body 3023. The cross section of the pipe body of the second sealing part 302 is triangular, and also has good stability and strong anti-collapse ability, and can maintain structural stability after the number of opening and closing of the box cover 2 increases.

[0065] Secondly, based on the purpose of further improving the sealing ability of the second sealing part 302, referring to Figures 1 to 3 The second sealing part 302 has an outwardly convex arc-shaped side wall 3024, which can abut against the second inner wall 202. Specifically, the arc-shaped side wall 3024 is arranged around the opening edge of the box 1, and from the cross section of the second sealing part 302, the cross section has an outwardly convex part. The provision of the outwardly convex arc-shaped side wall 3024 on the second sealing part 302 can increase the contact area between the second sealing part 302 and the second inner wall 202, and improve the sealing effect. In the embodiment, the arc-shaped side wall 3024 is provided at the connection between the third elastic body 3022 and the fourth elastic body 3023, and is closer to the third elastic body 3022 as a whole. After the box cover 2 is buckled, the second inner wall 202 will extrude the arc-shaped side wall 3024, causing the connection between the third elastic body 3022 and the fourth elastic body 3023 to deform inwardly of the box 1, which is beneficial to the sealing between the second sealing part 302 and the box cover 2.

[0066] Regarding the structural arrangement of the first sealing part 301, the first sealing part 301 of the embodiment has a first cavity 3011, which is arranged around the opening edge of the box 1. The provision of the first cavity 3011 on the first sealing part 301 can make the first sealing part 301 more easily elastically deform to fully fit the first inner wall 201 when it is extruded by the first inner wall 201, thereby improving the sealing effect.

[0067] Further, the first sealing portion 301 has a first lip 3012 extending along a fastening direction of the box cover 2, and the first sealing portion 301 abuts against the first inner wall 201 at a position where the first lip 3012 is arranged, and the first lip 3012 is arranged around the opening edge of the box body 1. The fastening direction of the box cover 2 refers to a direction in which the box cover 2 moves relative to the first sealing portion 301 when the box cover 2 is continuously rotated after contacting the first sealing portion 301. The first lip 3012 can increase the sealing contact area between the first sealing portion 301 and the box cover 2 when the box cover 2 is closed, so that the first sealing portion 301 is better attached to the first inner wall 201, thereby improving the sealing effect.

[0068] Preferably, the first sealing portion 301 comprises a first elastic body 3013 and a second elastic body 3014 connected to each other, and the first lip 3012 is extended from the first elastic body 3013. The first elastic body 3013 and the second elastic body 3014 are arranged to support the first lip 3012 at the same time, thereby improving the anti-collapse capability of the first sealing portion 301 at the first lip 3012. The cross section of the sealing strip 3 at the first sealing portion 301 is substantially triangular in the embodiment, which has good stability and strong anti-collapse capability, and can maintain the structural stability well after the number of opening and closing of the box cover 2 increases.

[0069] Specifically, the first lip 3012 is bent towards the inside of the box body 1 after extending from the first elastic body 3013, so as to better attach the first lip 3012 to the first inner wall 201. The first elastic body 3013 and the second elastic body 3014 can be made of materials such as foamed ethylene propylene terpolymer, foamed polyurethane, and foamed polypropylene. In the embodiment, the first elastic body 3013 and the second elastic body 3014 are made of foamed ethylene propylene terpolymer.

[0070] Meanwhile, in order to control the deformation direction of the first sealing part 301 when it is pressed by the first inner wall 201, the side of the first sealing part 301 away from the opening direction of the box body 1 is outwardly convex, and an exhaust hole 3015 is arranged on the outwardly convex part. By arranging the side of the first sealing part 301 away from the opening direction of the box body 1 to be outwardly convex, the outwardly convex part of the first sealing part 301 is more likely to be bent and deformed when it is pressed by the first inner wall 201, and the deformation direction of the whole first sealing part 301 is controlled, which is conducive to improving the sealing effect. In combination with the specific shape of the first sealing part 301, the outwardly convex part of the first sealing part 301 corresponds to the second elastic body 3014, that is, the second elastic body 3014 is outwardly convex. When the first sealing part 301 is pressed by the first inner wall 201, the second elastic body 3014 deforms first to provide elastic force to make the first sealing part 301 tightly contact the first inner wall 201. The arrangement of the exhaust hole 3015 can balance the air pressure between the first chamber 3011 and the outside when the first sealing part 301 is pressed, so that the first sealing part 301 is more likely to deform when it is pressed by the box cover 2, thereby reducing the closing resistance of the box cover 2.

[0071] As to the arrangement form of the exhaust hole 3015, a plurality of exhaust holes 3015 can be arranged at intervals along the extension direction of the first sealing part 301. Preferably, the distance between adjacent exhaust holes 3015 ranges from 100mm to 200mm, and the exhaust hole 3015 is a circular hole. Meanwhile, the exhaust hole 3015 faces the fastening direction of the box cover 2.

[0072] In addition, as to the structure of the connection between the sealing strip 3 and the box body 1, the sealing strip 3 of the present embodiment comprises a sealing strip body 303, and the sealing strip body 303 is provided with a mounting groove 3031 for the opening edge of the box body 1. The first sealing part 301 is connected to the side of the sealing strip body 303 away from the box body 1, and the second sealing part 302 is connected to the side of the sealing strip body 303 facing the opening direction of the box body 1. By arranging the sealing strip body 303 with the mounting groove 3031, the sealing strip 3 can be conveniently mounted on the opening edge of the box body 1. By arranging the first sealing part 301 and the second sealing part 302 on different sides of the sealing strip body 303, the sealing position between the box body 1 and the box cover 2 can be enriched, and the overall sealing effect can be improved.

[0073] In detail, the sealing strip body 303 is in the shape of a Chinese character, and the skeleton 3034 is embedded in the sealing strip body 303. When the sealing strip 3 is installed, the opening of the installation groove 3031 is simply aligned with the opening edge of the box body 1 and then sleeved, which is simple and convenient. The skeleton 3034 is embedded in the sealing strip 3 to improve the overall structural strength of the sealing strip 3, so that the skeleton 3034 shares some local stress and reduces the possibility of cracking, elongation, distortion and other problems of the sealing strip 3 due to stress. Specifically, the skeleton 3034 can be made of metal material, and the skeleton 3034 of the embodiment is made of steel material.

[0074] For example, the first elastic body 3013, the second elastic body 3014, the third elastic body 3022 and the fourth elastic body 3023 of the embodiment are directly connected with the sealing strip body 303, which is relatively simple in structure and facilitates the molding and manufacturing of the sealing strip 3. It should be noted that if the first sealing part 301 or the second sealing part 302 adopts a tubular form, the first sealing part 301 or the second sealing part 302 can be bonded to the sealing strip body 303, which can make the process of manufacturing the sealing strip 3 more simple.

[0075] Further, in order to improve the firmness of the connection between the sealing strip body 303 and the box body 1, the anti-falling lip 3032 capable of abutting against the box body 1 is arranged on the groove wall of the installation groove 3031 and extends obliquely towards the groove bottom of the installation groove 3031. The anti-falling lip 3032 can be clamped on the opening edge of the box body 1, and there is a friction force between the anti-falling lip 3032 and the box body 1. When the box body 1 tends to separate from the installation groove 3031, the anti-falling lip 3032 can hinder the box body 1 from separating from the installation groove 3031 by the elastic force of the anti-falling lip 3032 and the friction force between the anti-falling lip 3032 and the box body 1, thereby improving the firmness of the installation of the sealing strip 3.

[0076] Specifically, the anti-falling lip 3032 of the embodiment is arranged outwardly convex to the opening of the installation groove 3031. When the opening edge of the box body 1 moves outwardly from the installation groove 3031, the anti-falling lip 3032 remains in contact with the box body 1 and is bent, thereby further hindering the opening edge of the box body 1 from moving out of the installation groove 3031. The number of anti-falling lips 3032 can be set to multiple, and the multiple anti-falling lips 3032 are arranged in parallel at intervals, which is beneficial to improving the anti-falling ability of the sealing strip body 303. The sealing strip body 303 of the embodiment is provided with two anti-falling lips 3032, which has good anti-falling effect and also makes the resistance not too large when the sealing strip 3 is installed on the opening edge of the box body 1.

[0077] Secondly, in order to position the horizontal position of the sealing strip 3 on the box body 1, the mounting groove 3031 of the embodiment is provided with a positioning protrusion 3033 abutting against the box body 1. The positioning protrusion 3033 is arranged on the groove wall of the mounting groove 3031. When the positioning protrusion 3033 abuts against the box body 1, the horizontal position of the sealing strip 3 can be positioned, and the friction between the sealing strip body 303 and the box body 1 is improved, thereby preventing the sealing strip 3 from falling off. For example, the positioning protrusion 3033 and the anti-falling lip 3032 are arranged on opposite sides of the mounting groove 3031. The positioning protrusion 3033 and the anti-falling lip 3032 can jointly abut against the box body 1, so that the sealing strip 3 is not easy to fall off after being mounted.

[0078] In detail, the number of the positioning protrusions 3033 can be multiple, and the multiple positioning protrusions 3033 are arranged in parallel at intervals. The positioning protrusions 3033 can be a complete ring surrounding the mounting groove 3031, or multiple protrusions arranged around the mounting groove 3031. Both of the two ways can prevent the sealing strip 3 from falling off.

[0079] Preferably, the positioning protrusions 3033 of the embodiment are complete annular and arranged at intervals along the opening direction of the mounting groove 3031, and the number of the positioning protrusions 3033 is three. The sealing strip 3 has better anti-falling effect, and the resistance of the sealing strip 3 to the box body 1 is not too large when the sealing strip 3 is mounted to the opening edge of the box body 1. For the cross-sectional shape of the positioning protrusion 3033, the cross section of the positioning protrusion 3033 is generally a right triangle. One of the right angles of the right triangle coincides with the inner wall of the mounting groove 3031, and the other right angle is arranged in parallel with the groove bottom of the mounting groove 3031. The part of the positioning protrusion 3033 in contact with the opening edge of the box body 1 is provided with a round corner. When the positioning protrusion 3033 is extruded by the box body 1, the round corner can make the contact area between the positioning protrusion 3033 and the box body 1 larger, thereby improving the anti-skid effect of the positioning protrusion 3033.

[0080] Reference Figure 3 On the basis that the sealing strip 3 has the sealing strip body 303, the first sealing part 301 and the second sealing part 302, the sealing strip body 303 is made of dense glue, and the first sealing part 301 and the second sealing part 302 are made of sponge rubber. The sealing strip body 303 is made of dense glue, which has good structural strength and is beneficial to improving the connection firmness between the sealing strip 3 and the box body 2. The first sealing part 301 and the second sealing part 302 are made of sponge rubber, which has good elasticity and flexibility and can make the first sealing part 301 and the second sealing part 302 adhere more closely to the box cover 2.

[0081] Preferably, the material of the sealing strip body 303 in the embodiment is EPDM (Ethylene Propylene Diene Monomer) dense rubber, and the materials of the first sealing part 301 and the second sealing part 302 are EPDM sponge rubber. The EPDM sponge rubber has good water resistance and strong weather resistance, and is suitable for use as a sealing part. Of course, one or more of the sealing strip body 303, the first sealing part 301, and the second sealing part 302 can also be made of materials such as silicone rubber and chloroprene rubber.

[0082] Secondly, at least one of the first sealing part 301 and the second sealing part 302 is covered with a coating 4 on the side facing the box cover 2. Specifically, in combination with Figure 3 As shown in the figure, the coating is located outside the connection between the third elastic body 3022 and the fourth elastic body 3023, outside the third elastic body 3022, outside part of the sealing strip body 303, outside the first elastic body 3013, and outside the first lip 3012. The coating 4 is continuous and surrounds the sealing strip 3. The purpose is to increase the wear resistance of the contact part between the first sealing part 301 and the second sealing part 302 and the box cover 2, and to improve the service life. Of course, it is also possible to only spray the coating 4 on the first sealing part 301 or the second sealing part 302.

[0083] Preferably, the thickness of the coating 4 is 10-16 μm. It should be noted that Figure 3 Figure 3 The red part of the coating 4 is the easily-worn part of the contact between the sealing strip 3 and the box cover 2, and the coating 4 is sprayed thicker. The blue part mainly plays a role in appearance, and the coating 4 is sprayed thinner. The specific material of the coating 4 is PU (polyurethane). PU as the coating 4 can form a smooth and low-friction surface, reduce the frictional resistance between the sealing strip 3 and the box cover 2, and improve the wear resistance of the sealing strip 3. Of course, the coating 4 can also be made of organic silicon material.

[0084] In a conventional luggage design, the box cover 2 is hingedly connected to the box body 1. When the box cover 2 is buckled at the opening of the box body 1, in the vertical direction, the distance between the box body 1 and the box cover 2 is larger near the hinge, and the distance between the box body 1 and the box cover 2 is smaller away from the hinge. That is, after the box cover 2 is closed, the interference amount of the second sealing part 302 and the box cover 2 away from the hinge is greater than that near the hinge. If the design of the second sealing part 302 is to have a large interference amount with the box cover 2 near the hinge, it may cause the interference amount of the second sealing part 302 and the box cover 2 away from the hinge to be too large, causing the box cover 2 to be difficult to close.

[0085] In order to solve the problem, the second sealing part 302 is not attached to the box cover 2 near the hinge, that is, the second sealing part 302 contacts the box cover 2 and hardly extrudes the box cover 2. In this way, the interference between the second sealing part 302 and the box cover 2 far from the hinge can be controlled to a reasonable value, and the closing of the luggage case is not affected. At the same time, the first sealing part 301 can also compensate for the possible sealing problem of the second sealing part 302, and further improve the sealing reliability of the sealing strip 3.

[0086] The luggage sealing structure of the embodiment is designed as above, the sealing strip 3 with the first sealing part 301 and the second sealing part 302 is arranged, two sealing parts are formed between the box body 1 and the box cover 2, after any one sealing part fails, the other sealing part can still keep the box body 1 and the box cover 2 closed, and the sealing stability is improved. The structure design of the first sealing part 301 and the second sealing part 302 can improve the collapse resistance and the sealing reliability.

[0087] The above only describes some embodiments of the utility model and is not used for limiting the utility model, and the technical features or structures in the different embodiments can be combined to form other specific technical schemes according to the needs. The utility model can be changed and varied in various ways for those skilled in the art. Any modification, equivalent replacement, improvement and the like within the spirit and principle of the utility model should be included in the protection range of the claims of the utility model.
