[0036] Please also read Figures 1 to 7 Now, the hinge assembly and the vehicle provided by the utility model are described. The hinge assembly includes a vehicle body hinge seat 2 and a vehicle door hinge seat 1 rotatably connected to the vehicle body hinge seat 2, wherein the vehicle body hinge seat 2 is installed in a vehicle body water flow channel 301 outside the vehicle roof.

[0037] Compared with the prior art, the hinge assembly provided by the utility model has a vehicle body hinge seat arranged in a vehicle body water flow groove 301 outside the vehicle roof. The vehicle body water flow groove 301 is located at the top of the vehicle body. The vehicle body hinge seat 2 is installed therein, and the space inside the vehicle body will not be occupied. After the vehicle door 7 is opened, the vehicle body hinge seat 2 located outside the vehicle body can ensure that there is enough space for the passenger's head. In addition, since the vehicle body hinge seat 2 is installed in the vehicle body water flow groove 301, the vehicle body hinge seat 2 is prevented from protruding from the upper surface of the vehicle roof, thereby ensuring the smoothness of the vehicle roof surface, reducing the wind noise during vehicle driving, and also making the vehicle body appearance neater.

[0038] In some embodiments, see Figure 3 The door hinge seat 1 includes a mounting seat body 101 and a connecting arm 102. The mounting seat body 101 is installed in the water flow channel of the door 7; the connecting arm 102 is connected to the mounting seat body 101 and extends toward the inner side of the cab. The connecting arm 102 is rotatably connected to the vehicle body hinge seat 2.

[0039] In this embodiment, the mounting seat body 101 is connected to the vehicle door 7 to fix the vehicle door hinge seat 1, and the connecting arm 102 is rotatably connected to the vehicle body hinge seat 2. When the vehicle door 7 is opened or closed, the connecting arm 102 rotates around an axis parallel to the front-rear direction to flip the vehicle door 7 upward or downward. The connecting arm 102 extends to the inner side of the cab and is connected to the vehicle body hinge seat 2 to avoid occupying too much space of the vehicle door 7.

[0040] Optionally, the connecting arm 102 is rotatably connected to the vehicle body hinge seat 2 around an axis parallel to the front-rear direction.

[0041] In some embodiments, see Figures 4 to 5 The hinge assembly also includes a sealing component 6 connected to the vehicle body hinge seat 2. The sealing component 6 is located above the vehicle body hinge seat 2 and is provided with a clearance groove adapted to the door hinge seat 1.

[0042] The sealing assembly 6 is arranged above the vehicle body hinge seat 2 to shield the vehicle body hinge seat 2, preventing external impurities such as rainwater and dust from entering the cab through the holes of the vehicle body hinge seat 2, and ensuring a clean environment in the cab. When the vehicle door 7 is closed, the vehicle door hinge seat 1 is inserted into the clearance groove; when the vehicle door 7 is opened, the vehicle door hinge seat 1 passes through the clearance groove and rotates toward the vehicle body. The opening of the clearance groove prevents the sealing assembly 6 from interfering with the vehicle door hinge seat 1 when the vehicle door 7 is opened.

[0043] Optionally, the vehicle body hinge seat 2 is bonded or screwed to the vehicle body. Since screwing requires opening a hole in the vehicle body hinge seat 2, providing a sealing component 6 can prevent water from entering the cab through the hole. The bonding connection method requires a dry environment, and excessive humidity or water immersion will cause bonding failure.

[0044] In some embodiments, see Figure 5 The sealing assembly 6 includes a cover body 601 and a fixing member 603. The cover body 601 is covered on the top of the vehicle body hinge seat 2, and a clearance groove is opened in the cover body 601; the fixing member 603 is arranged at the bottom of the cover body 601 and connected to the bottom of the vehicle body hinge seat 2.

[0045] The fixing member 603 is connected to the vehicle body hinge seat 2 to fix the cover plate body 601. The cover plate body 601 is arranged above the vehicle body hinge seat 2. The cover plate body 601 shields the vehicle body hinge seat 2 to prevent external impurities such as rainwater and dust from entering the cab through the holes leaking from the vehicle body hinge seat 2, thereby ensuring a clean environment in the cab. In addition, the cover plate body 601 shields the holes leaking from the vehicle body hinge seat 2 and also extends the flow path of the internal and external airflow, thereby preventing the external airflow from entering the cab through the holes leaking from the vehicle body hinge seat 2 during vehicle driving, thereby reducing wind noise. The design of the clearance groove can prevent the cover plate body 601 from interfering with the door hinge seat 1 when the door 7 is opened.

[0046] As another implementation of the sealing assembly 6 , the sealing assembly 6 further includes a cover sealing strip 602 arranged around the outer edge of the cover body 601 .

[0047] A cover sealing strip 602 is arranged on the outer edge of the cover body 601. When the vehicle door 7 is closed, the cover sealing strip 602 is squeezed and sealed with the vehicle door hinge seat 1 to improve the sealing performance and prevent external rain or dust from entering the cab. In addition, the good sealing effect can also prevent air convection inside and outside the vehicle body and reduce wind noise during vehicle driving.

[0048] As a specific implementation of the fixing member 603, the fixing member 603 is provided with a first mounting hole, the first mounting hole is adapted to the second mounting hole on the vehicle body hinge seat 2, and the sealing assembly 6 also includes a locking member inserted into the first mounting hole and the second mounting hole.

[0049] The fixing member 603 can be processed into the first mounting hole by drilling or laser cutting, and the processing technology is simple. The fixing member 603 is connected to the vehicle body hinge seat 2 by inserting the locking member into the first mounting hole and the second mounting hole, which is simpler to operate than welding. Moreover, due to the limited space on the top of the vehicle body, the welding method is inconvenient to operate, and the welding process can avoid the occurrence of leaking welding.

[0050] Optionally, the locking member includes a bolt and a nut, the bolt is inserted into the first mounting hole and the second mounting hole, and the bolt is screwed to the bolt to lock the fixing member 603 to the vehicle body hinge seat 2. The locking member may also include only a bolt, wherein the first mounting hole and / or the second mounting hole is a threaded hole, and the fixing is achieved by screwing.

[0051] In some embodiments, see Figure 3 The vehicle body hinge seat 2 includes a fixed seat body 201, a first support ear 202 and a second support ear 203. The fixed seat body 201 is installed in the vehicle body water flow channel 301; the first support ear 202 is arranged on the fixed seat body 201, and the first support ear 202 is connected to the fixing piece 603; the second support ear 203 is arranged on the fixed seat body 201 and connected to the vehicle door hinge seat 1.

[0052] The first lug 202 is connected to the fixing member 603 to fix the cover body 601. The second lug 203 is connected to the door hinge seat 1. When the door 7 is opened or closed, the door hinge seat 1 rotates around the second lug 203. Compared with the solution of directly connecting the cover body 601 and the door hinge seat 1 to the fixing seat body 201, the solution in this embodiment can effectively avoid interference between the door hinge seat 1 and the cover body 601.

[0053] Optionally, there are multiple first ears 202 , and the multiple first ears 202 are sequentially distributed along the front-to-back direction. The second ear 203 is arranged between two adjacent first ears 202 .

[0054] Based on the same inventive concept, the utility model also provides a vehicle.

[0055] The vehicle provided by the utility model adopts the above-mentioned hinge assembly, and the body hinge seat is arranged in the body water flow groove 301 outside the roof. The body water flow groove 301 is located at the top of the vehicle body. The body hinge seat is installed here, and it will not occupy the space inside the vehicle body. After the door 7 is opened, the body hinge seat located outside the vehicle body can ensure that there is enough space for the passenger's head. In addition, since the body hinge seat 2 is installed in the body water flow groove 301, the body hinge seat is prevented from protruding from the upper surface of the roof, which ensures the smoothness of the roof surface, reduces the wind noise during the vehicle driving, and also makes the appearance of the vehicle body more neat.

[0056] In some embodiments, see Figure 1 to Figure 2 The vehicle further comprises a door seal strip 4 arranged on the inner side of the water flow channel 301 of the vehicle body, and the vehicle door 7 is interference fit with the door seal strip 4 when the vehicle door 7 is in a closed state.

[0057] When the vehicle door 7 is in the closed state, it has an interference fit with the door seal strip 4, and the gap between the vehicle door 7 and the vehicle body is sealed by extrusion sealing, thereby preventing rain or dust from entering the cab through the gap, thereby improving the sealing and cleanliness of the cab.

[0058] Optionally, when the vehicle is provided with a sealing assembly 6 , the sealing assembly 6 is located above the door seal strip 4 and squeezes the door seal strip 4 to improve the sealing performance in the vehicle body water channel 301 .

[0059] In some embodiments, see Figure 6 to Figure 7 The hinge mounting member 3 is further provided with a mounting groove 302 , which is arranged around the outer periphery of the vehicle body water flow groove 301 and is communicated with the vehicle body water flow groove 301 , and the door gap sealing strip 4 is arranged in the mounting groove 302 .

[0060] The door seal strip 4 is embedded in the mounting groove 302 to prevent the door seal strip 4 from protruding outwards from the surface of the roof, thereby ensuring the neatness of the exterior of the vehicle body. In addition, the mounting groove 302 provides support and position limiting for the door seal strip 4, thereby ensuring the firmness of the connection of the door seal strip 4.

[0061] Specifically, the installation groove 302 and the vehicle body water flow groove 301 form a stepped groove body, and the installation groove 302 is located above the vehicle body water flow groove 301 .

[0062] In some embodiments, see Figure 7 The vehicle also includes a door frame sealing strip 5 arranged in the water flow channel 301 of the vehicle body. The door frame sealing strip 5 and the door gap sealing strip 4 are respectively located on opposite sides of the vehicle body hinge seat 2, and the door gap sealing strip 4 has a fixing groove that is plugged into and matched with the outer edge of the hinge mounting member 3.

[0063] The outer edge of the hinge mounting member 3 is inserted into the fixing groove to fix the door frame sealing strip 5. There is no need to drill holes in the door sealing strip and then fix it through connecting parts, which simplifies the installation steps, saves the intermediate connecting parts, and does not need to use sealant. When the vehicle door 7 is closed, the door frame sealing strip 5 abuts against the vehicle door 7 to prevent external rainwater or dust from entering the cab through the gap between the vehicle body water flow groove 301 and the vehicle door 7, thereby improving the sealing of the cab, not only preventing rainwater, dust and other impurities from flowing into the cab, ensuring a clean environment in the cab, but also preventing airflow from entering the cab along the gap during vehicle driving to generate wind noise.

[0064] Specifically, when the vehicle door 7 is closed, the door frame weather strip 5 abuts against the vehicle door 7 in the up-down direction.

[0065] In some embodiments, see Figure 6 to Figure 7 The hinge mounting member 3 has a mounting boss 303 for mounting the vehicle body hinge seat 2, and the mounting boss 303 is located in the vehicle body water flow channel 301.

[0066] The mounting boss 303 not only provides a mounting position for the vehicle body hinge seat 2 to facilitate fixing the vehicle body hinge seat 2, but also increases the overall strength of the hinge mounting member 3 compared to a flat design, thereby preventing the hinge mounting member 3 from deforming or breaking after being subjected to force.

[0067] Specifically, the mounting boss 303 protrudes upward from the upper surface of the body water channel 301. The above description is only a preferred embodiment of the utility model and is not intended to limit the utility model.
