The specific meaning of the above terms in the present utility model can be understood by those skilled in the art according to the specific circumstances.

The present embodiment discloses a vehicle which is mainly used for personnel driving and riding, and also for transporting goods.

As shown in fig. 1-2, the vehicle includes a frameless door assembly. The frameless door assembly includes a door body 21, a door glass 22, an outer water cut seal 23, and an inner water cut seal 24. The door body 21 is provided with a groove into which a portion of the door glass 22 is inserted. The outer water cutting sealing strip 23 and the inner water cutting sealing strip 24 are arranged on the notch of the groove. The outside water cut weather strip 23 is provided between the outer side surface of the door glass 22 and the outer side panel of the door body 21. The inner water cut weather strip 24 is provided between the inner side surface of the door glass 22 and the inner side panel of the door body 21.

The frameless door assembly differs from a conventional door in that: no frame is provided around the door glass 22. This results in the door glass 22 having only one end inserted into the recess of the door body 21, leaving the door glass 22 in a cantilevered state, and being prone to vibration.

In order to solve the above-mentioned technical problems, the present embodiment provides a sealing strip, which can improve the clamping effect of the sealing strip on the door glass 22, thereby reducing the vibration of the door glass 22. Such a sealing tape having a vibration damping effect may be applied to either one or both of the outer water cut sealing tape 23 and the inner water cut sealing tape 24. The vibration reduction effect is best when the outer water cut sealing strip 23 and the inner water cut sealing strip 24 are both sealing strips having the vibration reduction effect as described above. For the sake of beautiful appearance, the sealing strip having the vibration damping effect may be applied only to the outer water-cutting sealing strip 23, so that the vibration damping effect can be achieved. The structures of the weather strip when applied to the outside-water cut weather strip 23 and the inside-water cut weather strip 24 are substantially identical, and therefore, a specific structure of the weather strip having the vibration damping effect described above will be described below by taking the application to the outside-water cut weather strip 23 as an example.

As shown in fig. 3, the sealing strip with vibration damping effect includes a sealing strip body 11, an inner lip 12, and a plug core 14.

The weather strip body 11 includes an integrally formed flat plate portion 111 and a curved portion 112. One end of the flat plate portion 111 is connected to a bent portion 112, and the bent portion 112 is bent to one side of the flat plate portion 111 to form a J-shaped structure. The inner lip 12 is integrally formed on the other side of the flat plate portion 111. The weather strip is fastened to the outer panel of the door body, and the curved portion 112 is brought into contact with the door body 21 and the inner lip 12 is brought into contact with the door glass 22.

The inner lip 12 is also flat plate-shaped, the inner lip 12 and the flat plate part 111 are arranged at an included angle, and the space between the inner lip 12 and the flat plate part is a containing groove 13. Specifically, the angle between the inner lip 12 and the flat plate 111 is not greater than 60 degrees.

The plug core 14 is cylindrical or prismatic. The plug 14 is provided in the accommodation groove 13, and the inner lip 12 and the flat plate portion 111 are both abutted against the side face of the plug 14. When the inner lip 12 abuts against the door glass 22, the inner lip 12 is deformed by being pressed, and moves in a direction approaching the flat plate portion 111, and the stopper 14 can restrict the amount of deformation movement of the inner lip 12, thereby maintaining the pressing force of the inner lip 12 against the door glass 22, and reducing vibration of the door.

Further, for door assemblies of different sizes and shapes, only the plug core 14 of different diameters need be replaced to maintain the compressive force of the inner lip 12 against the door glass 22. Thus, the whole structure of the sealing strip does not need to be changed, and the cost is reduced. And the shape of the sealing strip is complex, and a large number of parameters need to be adjusted during redesign, so that the cost for adjusting the sealing strip die is high. However, the plug core 14 is in a regular geometric shape, and various requirements can be met by adjusting the diameter of the plug core, so that the design cost of the die is low, the design period is shortened, and the overall research and development period of the vehicle door is shortened.

The sealing strip body 11 and the inner lip 12 may be made of polyvinyl chloride (PVC), ethylene propylene rubber (EPDM), synthetic rubber modified polypropylene (PP-EPDM), or the like. The plug core 14 can be made of the same material as the sealing strip body 11, and can also be made of other materials, such as other hard plastics.

Further, the inside of the weather strip body 11 is provided with a skeleton 17. The skeleton 17 is made of a material with high hardness, and is not easy to deform. The skeleton 17 can play a role of supporting the flat plate part 111, when the inner lip 12 is pressed by the door glass 22, the skeleton 17 supports the flat plate part 111 so that the flat plate part 111 cannot deform, and meanwhile, the skeleton 17 also indirectly supports the plug core 14, so that the pressing force of the plug core 14 on the inner lip 12 is improved, and a better vibration reduction effect is realized.

Specifically, the frame 17 is provided inside the flat plate portion 111 and the bent portion 112, and the frame 17 is also J-shaped. The frame 17 is J-shaped, and one end of the J-shaped frame 17 is an arc-shaped bending section. The flat plate section of the skeleton is used for supporting the flat plate part 111 of the sealing strip body 11, and the bent section of the skeleton is buckled on the vehicle door body 21, so that the sealing strip body 11 is not easy to fall off from the vehicle door body 21.

The structure makes the plug core 14 squeeze the flat plate 111, and acts on the door body 21 through the bending section of the framework 17, so that the structural strength of the sealing strip body 11 is further improved, deformation caused by the squeezing of the plug core 14 is avoided, and the squeezing force and vibration reduction effect of the plug core 14 to the inner lip 12 are improved.

Further, the inner lip 12 has a first projection extending to one side of the receiving groove at an end away from the flat plate portion 111, and is capable of shielding an opening of a part of the receiving groove 13. One end of the flat plate portion 111 is connected to the second projecting portion 16. The second projection 16 extends to one side of the inner lip 12 to block the opening of the partial receiving groove 13 and to block a part of the outer lip. This structure allows the plug core 14 to be enclosed inside the accommodation groove 13, preventing the plug core 14 from being separated from the accommodation groove 13. And also prevents the inside of the receiving groove 13 and the plug 14 from being seen from the outside of the sealing strip, making the sealing strip more beautiful.

Since only one end of the first projecting portion 15 is connected to the inner lip 12, the other end is in an open state; only one end of the second projecting portion 16 is connected to the flat plate portion 111, and the other end is in an open state. And the first and

second protrusions

15 and 16 are made of an elastic material. When the plug core 14 is replaced, the accommodating groove 13 can be opened only by pulling out the first protruding part 15 and the second protruding part 16, so that the sealing strip is more convenient to use.

Thus far, the technical solution of the present utility model has been described in connection with the preferred embodiments shown in the drawings, but it is easily understood by those skilled in the art that the scope of protection of the present utility model is not limited to these specific embodiments. Equivalent modifications and substitutions for related technical features may be made by those skilled in the art without departing from the principles of the present utility model, and such modifications and substitutions will fall within the scope of the present utility model.
