In the description of the present utility model, unless otherwise specified, the meaning of "a plurality of" is two or more.
[0031] The following will describe in detail the specific embodiments of the present utility model with reference to the accompanying drawings.
[0032] Please refer to Figures 1 to 10 , a dust-proof and moisture-proof roof luggage case, including a case lid 1, a case body 2, a support member 4 for supporting the open state of the case lid relative to the case body, a locking member 5 for locking and opening the case lid 1 and the case body 2, and including: a flexible sealing ring 7, the flexible sealing ring 7 is disposed around the case lid 1 or the case body 2, and when the roof luggage case is in the closed state, it is in contact with both the case lid 1 and the case body 2 at the same time. The closed state refers to the state when the roof luggage case is closed and the locking member locks the case lid and the case body.
[0033] The flexible sealing ring 7 is disposed around and covers the case body 1 or the case lid 2. When the roof luggage case is in the closed state, the flexible sealing ring 7 contacts the case body 1 and the case lid 2 at the same time, sealing all the gaps between the case body 2 and the case lid 1 that communicate with the inside of the case and the outside world, so that the roof luggage case has a good dust-proof and moisture-proof effect. Using a flexible material can not only increase the sealing performance more fully, but also play a role in buffering and noise prevention when the luggage case is closed.
[0034] The flexible sealing ring 7 is of a hollow structure, so that even if there are production errors or deformations caused by use in the case body 2 and the case lid 1 of the roof luggage case, due to the sufficient compressible space, there is no gap left between the case body 2 and the case lid 1 in the closed state, greatly improving the dust-proof and moisture-proof effect of the roof luggage case.
[0035] Preferably, the compressible elastic height of the flexible sealing ring is 5-15 mm. The height refers to the thickness of the flexible sealing ring 7 in the height direction when installed on the roof luggage case.
[0036] Or the initial height of the flexible sealing ring is 6-16 mm, and the wall thickness is 0.5-2 mm. Thus, the corresponding compression height is within the range applicable to the roof luggage case.
[0037] The material of the flexible sealing ring 7 can be a rubber sealing ring or a flexible plastic sealing ring. Rubber materials include natural rubber, synthetic silica gel, EPDM, TPE and other rubbers; flexible plastic materials can be ABS plastic, PVC, etc. In this embodiment, the flexible sealing ring 7 is a hollow-structured rubber sealing ring. The rubber sealing ring has good elasticity and good performance such as oil resistance, acid and alkali resistance, and high temperature resistance, and can meet the sealing requirements in various environments. Preferably, the height of the rubber sealing ring is 9-11 mm, and the wall thickness is 0.9-1.2 mm.
[0038] Please refer to Figure 8, an annular mounting platform 11 is provided on the inner side wall of the lid 1 close to the top end face of the box body 2, and the flexible sealing ring 7 is arranged around the annular mounting platform 11. When the roof luggage case is in the closed state, the annular mounting platform 11 and the top end face of the box body 2 simultaneously press the flexible sealing ring 7 to obtain a good sealing effect.
[0039] In this embodiment, the top end face of the box body 2 is an annular planar shape adapted to the flexible sealing ring 7. The table top of the annular mounting platform 11 is an annular planar shape. The flexible sealing ring 7 is a rubber sealing ring with a D-shaped hollow structure. The planar part of the flexible sealing ring 7 is adhesively fixed to the annular mounting platform 11. With the structure set in this way, the installation is convenient and the sealing performance is good; the D-shaped hollow structure can save materials, has better elasticity, and can also increase the elastic space of the sealing ring. When the box body 2 and the lid 1 are closed, there is a larger buffer space to ensure that the box body 2 and the lid 1 are not deformed by the impact force.
[0040] In other embodiments, the flexible sealing ring 7 is a hollow structure rubber sealing ring with a planar upper end face, and the upper end face of the flexible sealing ring is adhesively fixed to the annular mounting platform. There are various ways to achieve the structure of the flexible sealing ring with a planar upper end face. In addition to the D-shaped space structure, there are also square hollow structures, trapezoidal hollow structures, or triangular hollow structures, etc. All can achieve the effects of saving materials and increasing the elastic space of the sealing ring.
[0041] In other preferred embodiments, the table top of the annular mounting platform 11 is an annular planar shape, the flexible sealing ring 7 is a square hollow structure, a trapezoidal hollow structure, or a triangular hollow structure, and the material of the flexible sealing ring 7 is rubber or polyvinyl chloride.
[0042] Please refer to Figure 2 , Figure 6 , Figure 8 and Figure 9 , in this embodiment, the side wall of the lid 1 below the annular mounting platform 11 is nested with the top side wall 21 of the box body 2. When the roof luggage case is in the closed state, the bottom side wall 12 of the lid 1 covers the outside of the top side wall 21 of the box body 2. Through the setting of the bottom side wall 12, when the roof luggage case is in the closed state, the sealing ring is in a state invisible to the outside. When the lid 1 is opened, the sealing ring is also in a concealed state, which does not affect the beauty and does not affect taking and placing items from the box body.
[0043] In other preferred embodiments, the annular mounting platform 11 is provided with an annular groove adapted to the flexible sealing ring 7, and the flexible sealing ring 7 is fixed in the groove of the annular mounting platform 11 by interference fit.
[0044] Please refer to Figures 1 to 7, the roof luggage case structure of this embodiment will be further described below. The roof luggage case includes a case lid 1 and a case body 2, and also includes a hinge member 3 located on one side of the roof luggage case for hingedly mating the case lid 1 and the case body 2, and the hinge member 3 is fixedly connected to the case lid 1 and the case body 2 by screws 6. There are at least two support members 4, which are respectively located at both ends of the roof luggage case for supporting the open state of the case lid 1 relative to the case body 2, and the support members 4 are fixedly connected to the case lid 1 and the case body 2 by screws 6.
[0045] A locking member 5 is located on the other side of the roof luggage case for locking and opening the case lid 1 and the case body 2, and the locking member 5 is fixedly connected to the case lid 1 and the case body 2 by screws 6.
[0046] Screws 6 are used to fix the connecting members between the case body 2 and the case lid 1, replacing the currently commonly used pin or rivet method, so that the structure of this roof luggage case will not expose the pin heads or rivet heads on the outer surface of the case body 2, and there is no need to add plastic covers to the exposed pin heads or rivet heads, which brings extra trouble. And when the lock head 53 needs to be replaced, the method of screwing out the screws 6 with a screwdriver is simple and easy, and will not damage the lock head 53 of the lock.
[0047] In this embodiment, the screw heads of the screws 6 are located on the outer surfaces of the case lid 1 and the case body 2, and nuts adapted to the screws 6 are provided inside the case lid 1 and the case body 2 to increase the fastening performance of the screws and facilitate disassembly.

For example, the nut + gasket method is used for fastening; internal threaded holes are provided on the hinge member, support member or locking member, and the screw passes through the internal threaded hole and is locked with a screw; or two nuts are stacked and locked, and glue is applied to the thread. Or preferably, self-locking nuts are used. The principle of self-locking nuts is to process special structures on the thread to increase the friction force, so that the nuts are not easily loosened. Common self-locking nuts include washer-type self-locking nuts, end-face flat-type self-locking nuts and internal-lock flat-type self-locking nuts, etc.
[0049] In this embodiment, the nut is a locknut 61. The locknut has excellent anti-vibration performance, strong wear resistance and anti-shear ability, and good reusability. The setting of the locknut 61 can strengthen the firmness of the fixation of the screws 6. When disassembling, only the screw head needs to be screwed with a screwdriver and the locknut 61 needs to be screwed with a wrench, which will not damage the structure of the lock head 53 of the lock and will not damage other connecting members.
[0050] In order to make the outer surface of the luggage case smoother, in a preferred embodiment, the lid 1 and the case body 2 are provided with stepped through holes corresponding to the screws 6. The stepped through holes are large-diameter through holes in the part close to the outer surface of the lid 1 or the case body 2, and small-diameter through holes in the part far away. The main body part of the screw 6 fits with the small-diameter through hole part, and the screw head of the screw 6 is located in the large-diameter through hole of the stepped through hole.
[0051] Among them, the screw head of the screw 6 is circular, and the stepped through hole is adapted to the screw head, that is, the large-diameter through hole of the stepped through hole basically coincides with the diameter of the screw head, and the gap is very small. And after the screw 6 is installed in the stepped through hole, the screw head of the screw 6 is flush with the outer surface of the lid 1 or the case body 2, and the screw 6 is an internal hexagonal structure or other concave structures.
[0052] Among them, preferably, the screw head of the screw 6 is an internal hexagonal structure, an internal single-slot structure or an internal cross-slot structure, an internal multi-slot structure, an internal cross-slot structure or an internal anti-theft groove structure.
[0053] When the luggage case does not have a stepped through hole, the top of the screw head to the outer wall is an arc-shaped smooth structure.
[0054] Please refer to Figure 2 , in this embodiment, the screw head of the screw 6 is an internal hexagonal structure, and the top of the screw head to the outer wall is an arc-shaped smooth structure.
[0055] The locking member 5 includes at least two lock catches 51 provided on the lid 1, at least two lock seats 52 provided on the case body 2, and an unlocking unit;

When the hinged lock bar 521 moves outside the hinged lock hole, the lock catch 51 is in a disengaged state relative to the lock seat 52, and at this time the case body 2 and the lid 1 can be opened. When the hinged lock bar 521 moves into the hinged lock hole, the lock catch 51 is in a locked state relative to the lock seat 52.
[0057] Please refer to Figure 4The unlocking unit includes a lock head 53 provided with a keyhole, a fixing plate 54 fixedly arranged on the box body 2, and an unlocking square rod 55 slidably fitted on the fixing plate 54; a lock tongue 56 enabling the unlocking square rod 55 to slide along the fixing plate 54 is arranged on the lock head 53, and the articulated lock bar 521 slides along with the unlocking square rod 55 to disengage and lock the lock catch 51 relative to the lock seat 52.
[0058] In other embodiments, the lock seat 52 is directly connected to the box body 2 through screws 6 and locknuts 61. In this embodiment, the fixing plate 54 is fixed to the box body 2 through screws 6 and locknuts 61, and the fixing plate 54 is snapped into the mounting hole of the lock seat 52 for fixation.
[0059] The support member 4 includes an upper support rod 41, a lower support rod 42, and two fixing seats 43. The two fixing seats 43 are respectively fixed to the box body 2 and the box cover 1 through screws 6 and locknuts 61.
