Technical Field

[0001] This invention relates to the field of vehicle technology, and in particular to a cab sealing structure and a vehicle. Background Technology

[0002] Currently, a sealing structure is generally used between the vehicle cab door and the vehicle body to improve the sealing performance around the door, thereby improving the air conditioning performance and NVH performance such as driving noise.

[0003] Typically, sealing strips are used to seal the gap between the car door and the outer side panel. The sealing method usually involves adhesive bonding and snap-fit ​​connection, which allows the sealing strip to be installed on the outer side panel.

[0004] However, this method requires the simultaneous opening of buckle holes on the outer side panel. However, rainwater and other foreign objects can easily enter the cab through the buckle holes, and driving noise and other sounds can also easily enter the cab through the buckle holes, thus affecting the sealing performance of the cab. Summary of the Invention

[0005] The main objective of this invention is to provide a cab sealing structure that improves the sealing performance of the cab and enhances the vehicle's NVH performance.

[0006] To achieve the above objectives, the present invention provides a cab sealing structure comprising:

[0011] Optionally, the flange edge is integrally formed with the side panel.

[0012] Optionally, the flange edge is a bent sheet metal structure.

[0013] Optionally, the flange edge comprises a first mounting edge, a second mounting edge and a third mounting edge connected in sequence, the first mounting edge extends to the front end of the side outer plate at the first connecting part, the second mounting edge is connected to one side of the first mounting edge away from the first connecting part and extends to the outside of the side outer plate, and the third mounting edge is connected to one side of the second mounting edge away from the first mounting edge and extends to the front end of the side outer plate; the first sealing strip comprises a first sealing part and a first fixing part, the first fixing part is connected with the second mounting edge and the third mounting edge, and the first sealing part blocks the gap between the door assembly and the side outer plate when the door assembly is closed.

[0014] Optionally, the first fixing part is formed with a fixing groove, a fixing tooth is arranged in the fixing groove, the fixing tooth is connected with the second mounting edge, and the third mounting edge abuts against the groove bottom of the fixing groove.

[0015] Optionally, the first sealing part is formed with a sealing lip, one side of the sealing lip abuts against the side outer plate, and the other side of the sealing lip abuts against the door assembly when the door assembly is closed, so as to block the gap between the door assembly and the side outer plate.

[0016] Optionally, the cab sealing structure further comprises a B-pillar inner plate, the B-pillar inner plate is connected with the door frame to form a second connecting part, and a second sealing strip is clamped at the second connecting part.

[0017] Optionally, the second sealing strip comprises a second fixing part and a second sealing part, the second fixing part is connected with the second connecting part, one side of the second sealing part abuts against the door frame, and the other side of the second sealing part abuts against the door assembly when the door assembly is closed, so as to block the gap between the door assembly and the door frame.

[0018] Optionally, a through hole is arranged in the lower part of the side outer plate, and the through hole is used for mounting a toolbox door.

[0019] The application further provides a vehicle comprising the cab sealing structure.

[0020] In one technical solution of the present invention, the side panel outer plate is connected to the door frame to form a first connecting part. A flange is provided at the first connecting part, and a first sealing strip is snapped onto the flange. When the door assembly is closed, the first sealing strip seals the gap between the door assembly and the side panel outer plate. Thus, a sealing structure is formed between the door assembly and the side panel outer plate when the door assembly is closed. Compared to the prior art, which requires opening a snap-fit ​​hole in the side panel outer plate to adhere and snap the first sealing strip onto it, the present invention, by providing a flange and snapping the first sealing strip onto the flange, can seal the gap between the door assembly and the side panel outer plate when the door assembly is closed. This avoids opening a snap-fit ​​hole in the side panel outer plate, thereby preventing rainwater and other foreign objects from entering the cab due to snap-fit ​​holes, and also preventing external noise such as driving noise from entering the cab through snap-fit ​​holes. This improves the sealing performance and reliability of the cab, enhances the vehicle's NVH performance, and also improves the aesthetics of the side panel outer plate. Compared to the existing technology that fixes the first sealing strip to the outer side panel by bonding, the present invention secures the first sealing strip to the outer side panel by snapping it onto the flange edge. This avoids the problem of high requirements for bonding assembly process and also avoids the problem of the first sealing strip falling off due to aging of the adhesive or insufficient cleanliness of the bonding area, thereby improving the sealing reliability of the cab.

[0030] At present, the vehicle cab door and the vehicle body are generally sealed to improve the sealing performance of the door periphery, and thus improve the air conditioning performance of the cab and the NVH performance such as driving noise.

[0031] Generally, the sealant strip is used between the door and the side outer panel, and the sealant strip is generally installed on the side outer panel by the bonding and buckle connection.

[0032] However, the buckle hole needs to be simultaneously provided on the side outer panel, and rainwater and other foreign matters are easy to enter the cab through the buckle hole, and the sound such as driving noise is also easy to enter the cab through the buckle hole, thereby affecting the sealing performance of the cab.

[0033] In view of this, the present application provides a cab sealing structure.

[0034] Please refer to Figure 1 and Figure 2In the embodiment of the present application, the cab sealing structure comprises a door frame 100, a door assembly 200, a side outer plate 300, and a first sealing strip 400.
