Description

Technical Field

[0001] The utility model belongs to the technical field of tail boxes and relates to a waterproof tail box. Background Art

[0002] A tail box is a box provided on the tail rack of a motorcycle or an electric vehicle for convenient storage. Existing tail boxes generally have a waterproof structure to prevent the items stored in the tail box from being wetted by rain.

[0003] For example, a Chinese patent document discloses a waterproof motorcycle rear tail box (application number: 202221524842.3), which includes a rear tail box body and a box cover. A waterproof device is installed on the upper outer wall of the rear tail box body. The waterproof device includes a surrounding plate. The inside of the surrounding plate is fixedly connected to the upper outer wall of the rear tail box body. A rubber ring is fixedly connected above the surrounding plate. The inner wall and the upper outer wall of the rubber ring are respectively in contact with the outer wall of the rear tail box body and the lower outer wall of the box cover. An inner box body is provided inside the surrounding plate. The outer wall of the inner box body is in clearance fit with the inner wall of the rear tail box body. A cross plate is fixedly connected below the inner box body. The outer wall of the cross plate is fixedly connected to the inner wall of the rear tail box body. A plurality of support plates are fixedly connected below the cross plate. The lower part of the support plates is fixedly connected to the inner wall of the rear tail box body.

[0004] The following deficiencies exist in the use of the waterproof motorcycle rear tail box: After being used for a period of time, the rubber ring fixedly connected above the surrounding plate will age and reduce the sealing performance, resulting in a poor waterproof effect. The rainwater flowing in from the gap will seep into the inner box body without a seal, thus wetting the items in the inner box body. Summary of the Invention

[0005] The purpose of the utility model is to provide a waterproof tail box in view of the above problems existing in the prior art. The technical problem to be solved by the utility model is how to improve the waterproof effect of the tail box.

[0006] The purpose of the utility model can be achieved by the following technical solutions:

[0007] A waterproof tail box includes a box body and a box cover. It is characterized in that the top of the box body has a surrounding diversion surface. The positions of the diversion surface on the front and rear sides of the box body are respectively arranged to slope downwards. The inner edge of the diversion surface has an upwardly extending annular water retaining wall. The box cover has a downwardly extending annular protection wall. The bottom of the annular protection wall abuts against the diversion surface.

[0008] This waterproof tail box is provided with a diversion surface around the top of the box body. At the same time, the positions of the diversion surface on the front and rear sides of the box body are set lower than the other positions. In addition, the inner edge of the diversion surface is provided with an upwardly extending annular water retaining wall. The bottom of the annular retaining wall on the box cover abuts against the diversion surface. On the one hand, the gap at the joint between the box cover and the box body is small, which can reduce the infiltration of rainwater. On the other hand, due to the existence of the annular water retaining wall, the rainwater infiltrated from the joint between the box cover and the box body cannot enter the interior of the box body. On the third hand, the rainwater infiltrated from the joint between the box cover and the box body will flow along the slope to the front and rear sides of the box body until it leaves the tail box due to the shape of the diversion surface being higher in the middle and lower on both sides, thereby improving the waterproof effect of the tail box. At the same time, the above structure does not occupy the storage space inside the box body.

[0009] In the above-mentioned waterproof tail box, the bottom of the box cover is provided with a circumferentially arranged sealing surface. The annular retaining wall is arranged on the outer edge of the sealing surface. The inner edge of the sealing surface is provided with a downwardly extending annular abutting wall. The top of the annular water retaining wall is provided with an annular sealing ring, and the top of the annular sealing ring abuts against the sealing surface, and the inner side of the annular sealing ring abuts against the annular abutting wall. By setting the annular sealing ring, the sealing performance at the joint between the box cover and the box body can be further improved, and the rainwater infiltrated from the joint between the box cover and the box body can be further prevented from entering the box body, thereby improving the waterproof effect of the tail box.

[0010] In the above-mentioned waterproof tail box, the upper surface of the box cover is in the shape of a curved surface that is lower in the front and higher in the rear. This makes it difficult for rainwater to remain on the upper surface of the box cover, thereby improving the waterproof effect of the tail box.

[0011] In the above-mentioned waterproof tail box, a box cushion is provided at the bottom of the box body. A positioning plate that can move back and forth relative to the box body is also provided inside the bottom of the box body. A fixing groove is formed on the side of the positioning block facing the positioning plate. An elastic member is provided between the positioning plate and the box body. Under the action of the elastic member, the positioning plate is inserted into the fixing groove. The positioning plate is inserted into the fixing groove of the positioning block, and at the same time, by setting the elastic member, while enhancing the firmness of the fixation between the box body and the box cushion, the disassembly and assembly between the box body and the box cushion can be facilitated. During disassembly and assembly, the user only needs to overcome the elastic force of the elastic member to move the positioning plate to a position where it disengages from the fixing groove, and then move the box body obliquely upward so that the limiting portion disengages from the positioning groove and at the same time the positioning block disengages from the positioning hole.

[0012] In the above-mentioned waterproof tail box, the front and rear ends of the box cushion are respectively provided with a positioning block and a positioning groove. The bottom of the box body is provided with a positioning hole and a limiting portion. The positioning block is inserted into the positioning hole, and the limiting portion is inserted into the positioning groove. Further, the limiting portion of the box body is inserted into the positioning groove of the box cushion, and the positioning block of the box cushion is inserted into the positioning hole of the box body, thereby further enhancing the firmness of the fixation between the box body and the box cushion.

[0013] In the above-mentioned waterproof tail box, a mounting seat is detachably arranged on the inner side of the bottom of the box body. The mounting seat has a relief hole. The positioning hole and the elastic member are respectively located below the mounting seat. The elastic member is arranged along the front-back direction of the box body. One end of the elastic member is connected to the positioning plate, and the other end is connected to the mounting seat. The positioning plate has a protruding portion that extends out of the relief hole, and there is a moving space between the protruding portion and the hole wall of the relief hole. By providing the protruding portion, on the one hand, the protruding portion can form a limit with the hole wall of the relief hole to prevent the positioning plate from extending too far into the fixing groove under the action of the elastic member. On the other hand, when disassembling the box body and the gasket, the protruding portion can facilitate the user to hold the positioning plate by hand and move it out of the fixing groove, thus facilitating the disassembly and assembly of the box body and the gasket.

[0014] In the above-mentioned waterproof tail box, the end of the positioning plate close to the fixing groove gradually becomes narrower from bottom to top. This enables the positioning block on the gasket to more conveniently press the positioning plate and automatically insert it into the positioning hole of the box body, thus facilitating the fixing of the box body on the gasket and making the operation more convenient.

[0015] Compared with the prior art, the advantages of this waterproof tail box are as follows: This waterproof tail box is provided with a diversion surface around the top of the box body. At the same time, the positions of the diversion surface on the front and rear sides of the box body are set lower than the other positions. In addition, the inner edge of the diversion surface has an upwardly extending annular water retaining wall. The bottom of the annular protection wall on the box cover abuts against the diversion surface. Firstly, this makes the gap at the joint between the box cover and the box body smaller, and can reduce the infiltration of rainwater. Secondly, due to the existence of the annular water retaining wall, the rainwater infiltrating from the joint between the box cover and the box body cannot enter the interior of the box body. Thirdly, the rainwater infiltrating from the joint between the box cover and the box body will flow along the slope to the front and rear sides of the box body until it leaves the tail box due to the shape of the diversion surface being higher in the middle and lower on both sides, thereby improving the waterproof effect of the tail box.
