[0025] The embodiments of the present invention will be described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present invention will be described in detail below.

[0026] Below, reference is made to Figures 1-4 Describe the door assembly 1 according to the embodiment of the present invention.

[0027] As Figure 1 shown, the door assembly 1 according to the embodiment of the present invention includes: an upper side door 10, a lower side door 20, and a seal 30. The upper side door 10 and the lower side door 20 are components of the door assembly 1. The seal 30 is mainly a component for sealing the door, which can prevent water from entering the vehicle interior through the door assembly 1 when the sealing gap of the door assembly 1 is too large, thereby affecting the goods inside the vehicle.

[0028] As Figure 1 shown, the upper side door 10 includes: a first side plate 100 and a second side plate 101. Compared with the second side plate 101, the first side plate 100 is on the side closer to the outside of the vehicle. The first side plate 100 and the second side plate 101 are components of the upper side door 10. Compared with the second side plate 101, the first side plate 100 is on the side closer to the outside of the vehicle. The first side plate 100 and the second side plate 101 are arranged opposite to each other. The first side plate 100 is arranged on the side closer to the outside of the vehicle, and the second side plate 101 is arranged on the side away from the outside of the vehicle.

[0029] As Figure 1As shown, the lower door 20 and the upper door 10 are arranged opposite to each other vertically. The seal 30 is arranged between the upper door 10 and the lower door 20. The lower door 20 and the upper door 10 are arranged opposite to each other vertically, that is to say, the lower door 20 and the upper door 10 are of an up-and-down opening structure, generally the side door structure of a vehicle. Users can enter the cargo box from the side in the way of up-and-down opening to pick up goods. The seal 30 is arranged between the upper door 10 and the lower door 20, that is, the sealing strip 30 is arranged at the middle seam of the side door. In this way, when the sealing gap of the side door is too large, water can be prevented from entering the vehicle interior.

[0030] As Figure 1 and Figure 4 shown, the seal 30 includes: a first seal part 300 and a second seal part 301. The first seal part 300 is in interference fit with the first side plate 100, and the second seal part 301 overlaps the second side plate 101. Both the first seal part 300 and the second seal part 301 can play a sealing role. The first seal part 300 is in interference fit with the first side plate 100. At this time, the fit between the first seal part 300 and the first side plate 100 can be made closer, so as to improve the sealing effect between the first seal part 300 and the first side plate 100. The second seal part 301 overlaps the second side plate 101. At this time, the fit between the second seal part 301 and the second side plate 101 can be made closer, so as to improve the sealing effect between the second seal part 301 and the second side plate 101.

[0031] Thus, the seal 30 is provided with the first seal part 300 and the second seal part 301. At this time, the two-stage sealing of the door assembly 1 can be realized. The first stage of sealing is that the first seal part 300 is in interference fit with the first side plate 100, and the second stage of sealing is that the second seal part 301 overlaps the second side plate 101. In this way, when the sealing gap of the side door is too large and the first seal part 300 fails, the second seal part 301 can realize the second-stage sealing and waterproofing, so as to effectively prevent water from entering the vehicle interior.

[0032] Specifically, as Figure 1As shown, the interference fit amount between the first sealing part 300 and the first side plate 100 is a, the maximum outer diameter of the first sealing part 300 is d, the overlapping amount between the second sealing part 301 and the second side plate 101 is b, and the value ranges of a and b are: d / 3 ≤ a ≤ d / 2, 5mm ≤ b ≤ 6mm. It should be noted that the first sealing part 300 is constructed to be similar to an elliptical structure, and its maximum outer diameter is d. The interference fit amount a between the first sealing part 300 and the first side plate 100 needs to meet a certain range. Specifically, the interference fit amount a between the first sealing part 300 and the first side plate 100 cannot be too small, that is, less than d / 3. In this case, the interference fit amount a between the first sealing part 300 and the first side plate 100 is too small, which is not conducive to the arrangement of the first sealing part 300 at this time, and will affect the sealing effect of the first sealing part 300 on the vehicle door. At the same time, the interference fit amount a between the first sealing part 300 and the first side plate 100 cannot be too large, that is, greater than d / 2. In this case, the interference fit amount a between the first sealing part 300 and the first side plate 100 is too large, which will affect the arrangement of the first sealing part 300 at this time, and it is easy to damage the first sealing part 300 when the first sealing part 300 and the first side plate 100 are in interference fit, thus affecting the sealing effect of the first sealing part 300.

[0033] The overlapping amount b between the second sealing part 301 and the second side plate 101 needs to meet a certain range. Specifically, the overlapping amount b between the second sealing part 301 and the second side plate 101 cannot be too small, that is, less than 5mm. In this case, the overlapping amount b between the second sealing part 301 and the second side plate 101 is too small, which is not conducive to the arrangement of the second sealing part 301 at this time, and will affect the sealing effect of the second sealing part 301 on the vehicle door. At the same time, the overlapping amount b between the second sealing part 301 and the second side plate 101 cannot be too large, that is, greater than 6mm. In this case, the overlapping amount b between the second sealing part 301 and the second side plate 101 is too large, which will affect the arrangement of the second sealing part 301 at this time, and on the premise of ensuring the sealing effect of the second sealing part 301 on the vehicle door, it will cause waste of the second sealing part 301, thus wasting materials and increasing the manufacturing cost.

[0034] Among them, as Figure 1As shown, the lower door 20 is provided with a mounting portion 200 extending in the direction of the upper door 10. The seal 30 further includes: a main body portion 302, a first seal portion 300 and a second seal portion 301 are respectively connected to the main body portion 302. The main body portion 302 is provided with a bayonet 303, and the bayonet 303 is clamped on the mounting portion 200. The mounting portion 200 mainly serves for mounting. The mounting portion 200 is provided on the lower door 20 and extends in the direction of the upper door 10. The main body portion 302 is the main part of the seal 30 and can be used to connect and arrange other components. The first seal portion 300 and the second seal portion 301 are respectively connected to the main body portion 302. At this time, the first seal portion 300, the second seal portion 301 and the main body portion 302 form an integral body, which is convenient for the installation and arrangement of the seal 30. The bayonet 303 mainly serves for clamping. The bayonet 303 is clamped on the mounting portion 200. At this time, the seal 30 can be fitted on the lower door 20 through the clamping cooperation between the bayonet 303 and the mounting portion 200, and this can make the arrangement of the seal 30 more stable and firm.

[0035] In addition, as Figure 1 shown, the seal 30 further includes: a third seal portion 304 and a fourth seal portion 305. The third seal portion 304 and the fourth seal portion 305 are both connected within the bayonet 303. Moreover, the third seal portion 304 is in interference fit with the side of the mounting portion 200 away from the outside of the vehicle, and the fourth seal portion 305 is in contact with the side of the mounting portion 200 adjacent to the outside of the vehicle. The third seal portion 304 and the fourth seal portion 305 can both serve for sealing. The third seal portion 304 and the fourth seal portion 305 are both connected within the bayonet 303. At this time, the third seal portion 304, the fourth seal portion 305 and the main body portion 302 form an integral body, which is convenient for the installation and arrangement of the seal 30. The third seal portion 304 is in interference fit with the side of the mounting portion 200 away from the outside of the vehicle, so that the cooperation between the third seal portion 304 and the side of the mounting portion 200 away from the outside of the vehicle can be made closer, thereby improving the sealing effect between the third seal portion 304 and the side of the mounting portion 200 away from the outside of the vehicle. The fourth seal portion 305 is in contact with the side of the mounting portion 200 adjacent to the outside of the vehicle. Similarly, this can make the cooperation between the fourth seal portion 305 and the side of the mounting portion 200 adjacent to the outside of the vehicle closer, thereby improving the sealing effect between the fourth seal portion 305 and the side of the mounting portion 200 adjacent to the outside of the vehicle. At the same time, the seal 30 is clamped to the mounting portion 200 through the third seal portion 304 and the fourth seal portion 305, so that the installation and arrangement of the seal 30 on the lower door 20 can be realized.

[0036] Of course, as Figure 1As shown, the number of the third sealing portions 304 is less than that of the fourth sealing portions 305. It can be understood that since the third sealing portions 304 are in interference fit with the side of the mounting portion 200 away from the outside of the vehicle, and the fourth sealing portions 305 are attached to the side of the mounting portion 200 adjacent to the outside of the vehicle, the fourth sealing portions 305 are located on the outer side of the vehicle compared with the third sealing portions 304. The water on the outer side of the vehicle will first pass through the fourth sealing portions 305 and then through the third sealing portions 304. Therefore, the number of the third sealing portions 304 is less than that of the fourth sealing portions 305. Such a setting is more reasonable, which can improve the sealing effect of the fourth sealing portions 305 and at the same time reduce the setting of the third sealing portions 304, thereby reducing the cost. Among them, the number of the third sealing portions 304 can be two, and the number of the fourth sealing portions 305 can be three.

[0037] Furthermore, as Figure 1 shown, the interference fit amount between the third sealing portion 304 and the side of the mounting portion 200 away from the outside of the vehicle is c, and the value range of c is: 0.5mm ≤ c ≤ 1mm. It should be noted that the interference fit amount c between the third sealing portion 304 and the side of the mounting portion 200 away from the outside of the vehicle needs to meet a certain range. Specifically, the interference fit amount c between the third sealing portion 304 and the side of the mounting portion 200 away from the outside of the vehicle cannot be too small, that is, less than 0.5mm. In this case, the interference fit amount c between the third sealing portion 304 and the side of the mounting portion 200 away from the outside of the vehicle is too small, which is not conducive to the arrangement of the third sealing portion 304 and will affect the sealing effect of the third sealing portion 304 on the vehicle door. Moreover, if the interference fit amount c between the third sealing portion 304 and the side of the mounting portion 200 away from the outside of the vehicle is too small, it will affect the clamping effect between the bayonet 303 and the mounting portion 200. At the same time, the interference fit amount c between the third sealing portion 304 and the side of the mounting portion 200 away from the outside of the vehicle cannot be too large, that is, greater than 1mm. In this case, the interference fit amount c between the third sealing portion 304 and the side of the mounting portion 200 away from the outside of the vehicle is too large, which will affect the arrangement of the third sealing portion 304. In addition, if the interference fit amount c between the third sealing portion 304 and the side of the mounting portion 200 away from the outside of the vehicle is too large, it is easy to cause damage to the third sealing portion 304 when the third sealing portion 304 is fitted with the mounting portion 200, thereby affecting the sealing effect of the third sealing portion 304.

[0038] In addition, as Figure 1As shown, the lower end of the main body 302 is in interference fit with the lower side door 20, and the interference fit amount between the lower end of the main body 302 and the lower side door 20 is e, and the value range of e is: 1.5mm ≤ e ≤ 2mm. It should be noted that the lower end of the main body 302 is in interference fit with the lower side door 20, so that the fit between the lower end of the main body 302 and the lower side door 20 can be made closer, thereby improving the sealing effect between the lower end of the main body 302 and the lower side door 20 and preventing water from entering the vehicle interior through the gap between the lower end of the main body 302 and the lower side door 20.

[0039] At the same time, the interference fit amount e between the lower end of the main body 302 and the lower side door 20 needs to meet a certain range. Specifically, the interference fit amount e between the lower end of the main body 302 and the lower side door 20 cannot be too small, that is, less than 1.5mm. In this case, the interference fit amount e between the lower end of the main body 302 and the lower side door 20 is too small, which is not conducive to the layout of the main body 302 at this time, will affect the sealing effect of the seal 30 on the door, and the interference fit amount e between the lower end of the main body 302 and the lower side door 20 being too small will also affect the clamping effect between the bayonet 303 and the installation part 200. At the same time, the interference fit amount e between the lower end of the main body 302 and the lower side door 20 cannot be too large, that is, greater than 2mm. In this case, the interference fit amount e between the lower end of the main body 302 and the lower side door 20 is too large, which will affect the layout of the main body 302 at this time. At the same time, due to the excessive interference fit amount e between the lower end of the main body 302 and the lower side door 20, it is easy to cause damage to the main body 302 when the lower end of the main body 302 is fitted with the lower side door 20, thereby affecting the sealing effect between the lower end of the main body 302 and the lower side door 20.

[0040] It should be noted that as Figure 2 、 Figure 3 and Figure 4 shown, the seal 30 further includes: a water blocking part 306, and the water blocking part 306 is arranged on the main body 302 to block water in the up-down direction and left-right direction. The water blocking part 306 mainly plays a role in blocking water. The water blocking part 306 is arranged on the main body 302. At this time, the water blocking part 306 and the main body form an integral body, which is convenient for the installation and setting of the seal 30. At the same time, the water blocking part 302 can not only prevent water from entering in the left-right direction due to a large sealing gap, but also prevent water from entering in the up-down direction due to a large gap between the upper side door 10 and the lower side door 20, realizing water blocking in the up-down direction and left-right direction. Among them, the water blocking part 306 can be set as an L shape.

[0041] Optionally, as Figure 2 、 Figure 3 and Figure 4As shown, a water guide groove 307 is formed on the main body portion 302. The water guide groove 307 is located on the side of the water blocking portion 306 close to the interior of the vehicle. The water guide groove 307 mainly functions to guide water. Since the water guide groove 307 is located on the side of the water blocking portion 306 close to the interior of the vehicle, when the water volume is too large and the water blocking portion 306 cannot block the water, the water guide groove 307 can drain the water, preventing water from entering the vehicle interior when the water volume is excessive.
