[0047] In the following description, a large number of specific details are given to provide a more thorough understanding of the present invention. However, it is obvious to those skilled in the art that the present invention can be implemented without one or more of these details. In other examples, in order to avoid confusion with the present invention, some technical features known in the art are not described.

[0048] In order to fully understand the implementation of the present invention, a detailed structure will be presented in the following description. Obviously, the implementation of the implementation of the present invention is not limited to the specific details familiar to those skilled in the art.

[0049] It should be understood that the purpose of the terms used herein is only to describe specific embodiments and is not intended to limit the present invention, and the singular forms "a", "an" and "said / the" are also intended to include plural forms, unless the context clearly indicates otherwise. When the terms "comprise" and / or "include" are used in this specification, it indicates the presence of the features, integral bodies, steps, operations, elements and / or components, but does not exclude the presence or addition of one or more other features, integral bodies, steps, operations, elements, components and / or combinations thereof.

[0050] Ordinal numbers such as "first" and "second" cited in the present invention are merely identifiers and do not have any other meaning, such as a specific order. Moreover, for example, the term "first component" itself does not imply the existence of a "second component", and the term "second component" itself does not imply the existence of a "first component". It should be noted that the terms "upper", "lower", "front", "back", "left", "right", "inner", "outer" and similar expressions used in the present invention are for illustrative purposes only and are not limiting.

[0051] Hereinafter, specific embodiments of the present invention will be described in more detail with reference to the accompanying drawings. These drawings show representative embodiments of the present invention and are not intended to limit the present invention.

[0052] The sealing of the vehicle door opening area is mainly achieved by the door opening sealing strip installed at the stopper of the vehicle body side door opening. That is, the door opening sealing strip is an important component of the vehicle sealing system, and it cooperates with the vehicle door to play the role of waterproofing, dustproofing, noise reduction, etc. The door opening sealing strip usually includes the door opening side sealing strip, the door opening upper sealing strip and the door opening lower sealing strip. The door opening lower sealing strip is fixed at the stopper formed by the side outer panel and the side inner panel, and is mainly used to prevent water from flowing into the passenger compartment from the stopper under wading conditions and rainy conditions. In order to ensure sufficient sealing performance, the stopper is required to be as flat as possible without local mutations, and the stopper should not be too thick to prevent affecting the installation.

[0053] In the process of new energy development, automobile collision safety has become particularly important. Automobile side collision performance is an important part of vehicle safety performance evaluation and is directly related to the life safety of passengers. Pure electric vehicles generally set the battery pack at the bottom of the car, while the threshold structure of existing vehicles is separated from the battery pack frame. When the vehicle is hit from the side, the collision energy received by the vehicle side threshold structure is difficult to transfer to the longitudinal beam under the floor or the battery pack frame, so it is difficult to distribute the collision load more evenly on a larger force-bearing surface, affecting the vehicle's anti-collision performance and safety performance. When a side collision occurs, the body deformation space is small, so the risk of injury in a side collision is much higher than that in a frontal collision. In order to effectively deal with side collisions, the threshold design of vehicles in related technologies can generally maintain the same height as the battery pack to bear force together. However, the ground clearance of new energy sports cars is smaller and the threshold is relatively low. If the battery and the threshold height are set at the same height, when a side collision occurs, the threshold will be squeezed and deformed, and too much energy will be transferred to the battery pack, thereby affecting the vehicle's anti-collision performance and safety performance.

[0054] See also Figures 1 to 13The utility model provides a vehicle. The vehicle according to the utility model may include a rocker outer panel 111 and a rocker inner panel 131. The rocker inner panel 131 is located on a side of the rocker outer panel 111 close to the passenger compartment in the vehicle width direction D1. In the vehicle height direction D3, the top of the rocker inner panel 131 is higher than the top of the rocker outer panel 111 in the vehicle height direction D3. The top of the rocker inner panel 131 here can be understood as the highest top surface of the rocker inner panel 131 in the vehicle height direction D3. The top of the rocker outer panel 111 here can be understood as the highest top surface of the rocker outer panel 111 in the vehicle height direction D3. It should be noted that the top of the rocker inner panel 131 here can be understood as included in the upper part of the rocker inner panel 131 to be mentioned below. Similarly, the top of the rocker outer panel 111 here can be understood as included in the upper part of the rocker outer panel 111 to be mentioned below.

[0055] The vehicle width direction D1 is the Y direction, the vehicle height direction D3 is the Z direction, and the vehicle front-rear direction or length direction D2 is the X direction.

[0056] According to the vehicle of the utility model, by setting the height of the threshold inner panel higher than the threshold outer panel, the side impact resistance performance of the threshold structure of the vehicle can be improved while ensuring that the upper part of the threshold outer panel does not increase with the increase of the threshold inner panel, which can effectively reduce the impact on the assembly of the sealing strip, thereby solving the sealing problem between the threshold inner panel and the vehicle door after the threshold inner panel is increased. The vehicle door determines the installation position of the sealing strip. Therefore, after the threshold inner panel is increased, it can be ensured that the position of the sealing strip does not increase accordingly.

[0057] For example, the lower part of the sill inner panel 131 is connected to the lower part of the sill outer panel 111. The vehicle may further include a connector. The connector is located between the sill inner panel 131 and the sill outer panel 111. The upper part of the sill inner panel 131 is connected to the upper part of the sill outer panel 111 through the connector to enclose a receiving cavity 150. By providing the connector, the upper part of the sill outer panel 111 and the upper part of the sill inner panel 131 can be connected to close the gap between the upper part of the sill outer panel 111 and the upper part of the sill inner panel 131. In this way, the strength of the sill structure can be improved and the probability of water ingress can be reduced. Moreover, the receiving cavity 150 enclosed by the sill inner panel 131, the connector and the sill outer panel 111 is suitable for accommodating the sill reinforcement beam 160 to be mentioned below.

[0058] See also Figures 1 to 13In addition, the vehicle may further include a seal 170. The seal 170 is connected to the rocker inner panel 131 and the rocker outer panel 111. In the vehicle height direction D3, the height of the seal 170 is lower than the height of the top of the rocker inner panel 131. This ensures that the door forms a reliable seal with the rocker outer panel 111 through the seal 170, and at the same time, the rocker inner panel 131 can achieve functions such as side impact resistance and battery pack protection, thereby making the improved rocker structure compatible with the user's requirements for door sealing performance and rocker side impact resistance.

[0059] For example, at least part of the sealing member 170 can be directly or indirectly sealed between the rocker outer plate 111 and the rocker inner plate 131. By adding a sealing member, the door can be directly sealed with the vehicle body in cooperation with the vehicle door, thereby achieving the purpose of waterproofing.

[0060] Furthermore, the seal 170 is connected to the top of the rocker outer panel 111. In this way, the sharp edge of the rocker outer panel 111 can be used as a connection structure to install the seal 170, and the part of the seal 170 distributed between the rocker outer panel 111 and the rocker inner panel 131 can be used to close the groove structure (such as the groove structure formed between the rocker outer panel 111 and the rocker inner panel 131). Figure 7 As shown), rainwater is prevented from entering the accommodating cavity. The groove structure is formed by the rocker outer plate 111, the rocker inner plate 131 and the connecting member, and the opening faces upward.

[0061] For example, the sealing member 170 here can be constructed as a sealing strip made of soft elastic materials such as rubber, silicone rubber, etc.

[0062] See also Figure 7 and Fig.13 For example, the rocker outer panel may include a sealing connection portion 111a. In the vehicle width direction D1, the sealing connection portion 111a is spaced apart from at least part of the connecting member. At least part of the sealing member 170 is located between the sealing connection portion 111a and the connecting member.

[0063] See also Figures 1 to 13For example, the connecting member may include a first sealing plate 120. The first end of the first sealing plate 120 is connected to the rocker inner panel 131. The second end of the first sealing plate 120 is connected to the rocker reinforcement beam 160. The first sealing plate 120 is located on the side of the rocker outer panel 111 facing the passenger compartment along the vehicle width direction D1. And the first sealing plate 120 is spaced apart from the rocker outer panel 111 along the vehicle width direction D1. The rocker inner panel 131 is located on the side of the first sealing plate 120 away from the first sealing plate 120 in the vehicle width direction D1. The lower part of the rocker inner panel 131 is connected to the lower part of the rocker outer panel 111. The upper part of the rocker inner panel 131 is connected to the upper part of the first sealing plate 120. Specifically, the first end of the first sealing plate 120 has a first plate portion 121 extending along the vehicle height direction D3. The first plate portion 121 is connected to the rocker inner panel 131. The second end of the first sealing plate 120 has a second plate portion 122 extending along the vehicle width direction D1. The second plate portion 122 is connected to the rocker reinforcement beam 160 . The second plate portion 122 is located above the first plate portion 121 .

[0064] See also Figure 1 , Figures 7 to 12 In addition, the vehicle may further include a second sealing plate 140. The second sealing plate 140 is located at the interval between the rocker outer panel 111 and the first sealing plate 120 along the vehicle width direction D1 to close the opening between the rocker outer panel 111 and the first sealing plate 120. The second sealing plate 140 is connected to the rocker outer panel 111 and the first sealing plate 120 along the vehicle width direction D1. The second sealing plate 140, the rocker outer panel 111, the first sealing plate 120 and the rocker inner panel 131 enclose a receiving cavity 150. And at the connection between the second sealing plate 140 and the rocker outer panel 111, the upper part of the rocker outer panel 111 is protruded upward relative to the second sealing plate 140 along the vehicle height direction D3 for connecting a sealing strip. By using the second sealing plate 140, the opening between the rocker outer panel 111 and the first sealing plate 120 can be closed to improve the sealing between the rocker outer panel 111 and the rocker inner panel 131. At the same time, since the upper portion of the rocker outer panel 111 is arranged to protrude upward relative to the second sealing plate 140 , it is convenient to install a sealing strip on the upper portion of the rocker outer panel 111 , thereby further improving the sealing effect at the rocker.

[0065] See also Figure 7 and Fig.13 For example, the sealing connection portion 111a is extended along the vehicle height direction D3. And at the connection between the second cover plate 140 and the threshold outer plate 111. The sealing connection portion 111a is located on the upper side of the second cover plate 140 along the vehicle height direction D3. The sealing connection portion 111a here can be understood as the edge of the threshold outer plate 111 or the stop portion of the threshold outer plate 111 facing the door opening 100a. By providing the sealing connection portion 111a, it is easy to install the sealing strip.

[0066] Further, the second sealing plate 140 has a first end and a second end along the vehicle width direction D1. The first end of the second sealing plate 140 is connected to the first sealing plate 120. The second end of the second sealing plate 140 is connected to the rocker outer panel 111. Specifically, the first end of the second sealing plate 140 is connected to the surface of the rocker outer panel 111 facing the accommodating cavity 150 and the two are in surface contact with each other. The second end of the second sealing plate 140 is connected to the surface of the first sealing plate 120 facing the rocker outer panel 111 along the vehicle width direction D1 and the two are in surface contact with each other. The second sealing plate 140 is respectively connected to the rocker outer panel 111 and the first sealing plate 120 in the form of surface contact, which can improve the stability of the connection, while also increasing the force-bearing area and improving the force transmission performance.

[0067] See also Fig.13 , optionally, the second sealing plate 140 is arranged on a side of the first sealing plate 120 away from the rocker inner plate 131. At least part of the sealing member 170 is located between the sealing connection portion 111a and the first sealing plate 120. The second sealing plate 140 may include a third plate portion 141 and a fourth plate portion 142 that intersect each other. The third plate portion 141 is fitted and fixed to the first plate portion 121. The fourth plate portion 142 is fitted and fixed to the first sealing plate 120. That is, the first end of the second sealing plate 140 has a third plate portion 141 extending along the vehicle height direction D3. The third plate portion 141 is connected to the first sealing plate 120. The second end of the second sealing plate has a fourth plate portion 142 extending along the vehicle width direction D1. The fourth plate portion 142 is connected to the rocker outer plate 111. The third plate portion 141 is located on the upper part of the fourth plate portion 142, and the two are arranged to intersect. From the cross section of the second sealing plate 140, the second sealing plate 140 is an L-shaped cross section. The third plate portion 141 and the fourth plate portion 142 are two side edges of the L-shaped cross section respectively. The included angle between the third plate portion 141 and the fourth plate portion 142 can be set according to actual applications.

[0068] Furthermore, a groove structure 143 is provided at one end of the second sealing plate 140, which can better help improve the rigidity of the component.

[0069] See also Figures 1 to 13 For example, the surface of the rocker inner panel 131 away from the rocker outer panel 111 along the vehicle width direction D1 is recessed along the vehicle width direction D1 to form a limiting groove 132. The limiting groove 132 is lower than the upper part of the rocker outer panel 111 in the vehicle height direction D3. The limiting groove 132 is used to partially accommodate the battery pack. According to the vehicle of the utility model, the rocker inner panel 131 is formed with a limiting groove 132 for partially accommodating the battery pack, and the limiting groove 132 is lower than the upper part of the rocker outer panel 111 in the vehicle height direction D3. In this way, when a side collision occurs, the rocker can transfer part of the energy to the inner rocker located above the battery pack after being squeezed and deformed, thereby reducing the probability and degree of damage to the battery pack, and further helping to improve the collision resistance and safety performance of the vehicle to which the rocker structure is applied.

[0070] See also Figure 3 , Figure 7 and Fig.12 In addition, the vehicle may further include a threshold reinforcement beam 160. The threshold reinforcement beam 160 is located in the accommodating cavity 150. The lower portion of the first sealing plate 120 is connected to the threshold reinforcement beam 160. By providing the threshold reinforcement beam 160 and connecting the lower portion of the first sealing plate 120 to the threshold reinforcement beam 160, 160 forms a force transmission path between the threshold inner plate 131 and the threshold reinforcement beam 160, and also strengthens the structural strength of the inner threshold. When dealing with a side collision, the threshold structure has a stronger impact resistance and can further protect the safety of the occupants of the vehicle and the battery pack at the bottom of the vehicle.

[0071] For example, the rocker reinforcement beam 160 is connected to the rocker inner panel 131 in the vehicle length direction D2 and the vehicle width direction D1. The rocker reinforcement beam 160 is connected to the rocker outer panel 111 in the vehicle width direction D1.

[0072] Furthermore, the rocker reinforcement beam 160 may be fixed to the rocker outer panel 111 , the second cover panel 140 and the rocker inner panel 131 by means of structural adhesive or the like.

[0073] Continue reading Figure 3 , Figure 7 and Fig.12 For example, the first sealing plate 120 may include a first plate portion 121 and a second plate portion 122. The first plate portion 121 is extended along the vehicle height direction D3. The second plate portion 122 is connected to the upper end of the first plate portion 121 and is extended toward the rocker inner plate 131 in a direction intersecting the first plate portion 121. That is, the upper end of the first sealing plate 120 is bent toward the rocker inner plate 131 along the vehicle width direction D1 to form the second plate portion 122. The first plate portion 121 is located between the lower portion of the first sealing plate 120 and the second plate portion 122, and plays a role in supporting and transmitting force. The rocker inner plate 131 may include a first plate body 131a and a second plate body 131b. The first plate body 131a is extended along the vehicle height direction D3. That is, the upper portion of the rocker inner plate 131 is bent toward the first sealing plate 120 along the vehicle width direction D1 to form the second plate body 131b. The second plate 131b is connected to the upper end of the first plate 131a and extends toward the first sealing plate 120 in a direction intersecting the first plate 131a. The second plate 131b is parallel to the second plate portion 122 and is fixed to the upper portion of the second plate portion 122.

[0074] See also Figure 7Furthermore, in the vehicle height direction D3, the end of the second plate 131b away from the first plate 131a is higher than the first plate 131a. For example, the second plate 131b is inclined in the vehicle height direction D3. This helps to further increase the height of the inner door sill, and also increases the outward force-bearing area of ​​the inner door sill, which can further improve the anti-collision performance and safety.

[0075] See also Figures 1 to 13 The vehicle includes a body frame assembly 100. The body frame assembly 100 is formed with a door opening 100a. The body frame assembly 100 may include the above-mentioned threshold outer panel 111, threshold inner panel 131 and other structures. The threshold outer panel 111 and the threshold inner panel 131 are located at the lower side of the door opening 100a. According to the body frame assembly 100 of the utility model, by applying the above-mentioned threshold structure, the side impact resistance and safety performance of the vehicle body can be improved, and it also helps to protect the battery pack.

[0076] For example, the vehicle body frame assembly 100 may include a side panel outer panel 110 and a side panel inner panel 130. The edge of the side panel outer panel 110 facing the door opening 100a is used to clamp the sealing strip. The side panel outer panel 110 may include a rocker outer panel 111, that is, the rocker outer panel 111 is a part of the side panel outer panel 110 at the rocker. The side panel inner panel 130 includes a rocker inner panel 131, that is, the rocker inner panel 131 is a part of the side panel inner panel 130 at the rocker.

[0077] In the present utility model, in order to raise the height of the inner door sill, the side outer panel 110 and the side inner panel 130 at the door sill are partially staggered in the vehicle height direction D3. In order to close the opening area formed by the side outer panel 110 and the side inner panel 130 at the door sill, a connecting piece consisting of a first sealing plate 120 and a second sealing plate 140 is provided. The stopper of the side outer panel 110 at the door sill is used to clamp the sealing strip. At the rest of the door opening 100a, the stoppers of the side outer panel 110 and the side inner panel 130 are connected to each other and connected to the sealing strip together. It can be understood that the side outer panel 110 clamps a part of the annular sealing strip alone at the door sill, and the side outer panel 110 clamps the rest of the annular sealing strip together with the side inner panel 130 at the rest of the door opening 100a.

[0078] Optionally, the vehicle body frame assembly 100 may further include an A-pillar and a B-pillar. The B-pillar is spaced apart from the A-pillar along the vehicle length direction D2. The first sealing plate 120 is directly or indirectly connected to the A-pillar and the B-pillar. By connecting the first sealing plate 120 to the A-pillar and the B-pillar, the force transmission path of the threshold structure can be further increased, thereby improving the anti-collision performance.

[0079] For example, the vehicle body frame assembly 100 may be a structure made of carbon fiber.

[0080] For example, the side panel inner plate 130 integrates the A-pillar inner plate, the upper side beam inner plate, the B-pillar inner plate and the door sill inner plate 131. The upper sealing clamping portion of the door opening 100a is formed at the connection between the side panel outer plate 110 and the upper side beam inner plate of the side panel inner plate 130. Figure 1 As shown, the left sealing clamping part of the door opening 100a is formed at the connection between the side outer panel 110 and the A-pillar inner panel of the side inner panel 130. The right sealing clamping part of the door opening 100a is formed at the connection between the side outer panel 110 and the B-pillar inner panel of the side inner panel 130. The upper sealing clamping part of the door opening 100a and the sealing clamping parts on both sides form the upper left sealing clamping part of the curved corner and the upper right sealing clamping part of the curved corner. The lower sealing clamping part of the door opening 100a is formed at the connection between the side outer panel 110, the side inner panel 130, the first sealing plate 120 and the second sealing plate 140. The lower sealing clamping part of the door opening 100a here is the above-mentioned sealing connection part 111a. The lower left sealing clamping part of the curved corner is formed at the connection between the side outer panel 110, the second sealing plate 140 and the A-pillar inner panel of the side inner panel 130. The right lower corner sealing clamping part is formed at the connection of the B-pillar inner plate of the side outer panel 110 and the side inner panel 130. The entire door opening 100a sealing clamping part is composed of 8 parts, including the upper sealing clamping part, the left sealing clamping part, the right sealing clamping part, the upper left corner sealing clamping part, the upper right corner sealing clamping part, the lower sealing clamping part, the lower left corner sealing clamping part, and the lower right corner sealing clamping part. The specific size can be set according to the needs of actual application.

[0081] When designing the sealing of the door opening 100a, the cross-sectional structures of the upper sealing clamping part, the left sealing clamping part, the right sealing clamping part, the upper left sealing clamping part of the curved corner, the upper right sealing clamping part of the curved corner, the lower left sealing clamping part of the curved corner, and the lower right sealing clamping part of the curved corner can be the same as the traditional sealing structure, and can be sealed at the stop of the door opening by a sealing strip. The sealing strip here is a sealing structure arranged on the stop of the door opening of the side wall of the vehicle body, and the sealing strip cooperates with the vehicle door to play the role of waterproof, dustproof and noise reduction.

[0082] When assembling the lower sealing clamping part, first, the side inner panel 130 and the side outer panel 110 construct a cavity to meet the force transmission requirements of side collision. The overlapping area between the side inner panel 130 and the side outer panel 110 is sealed by structural adhesive to complete the first sealing. Between the side inner panel 130 and the side outer panel 110, there will be a part that is difficult to fit with the structural adhesive. At the same time, the original inner panel sealing structure cannot smoothly achieve the problem of change in the force transmission path caused by the heightening of the door sill. Therefore, it is considered to extend the front and rear ends of the first sealing plate 120 upward to form a C-shaped connection structure. The C-shaped connection structure can fit with the side inner panel 130. At this time, when the lengthened first sealing plate 120 is connected to the second sealing plate 140, it can achieve complete internal fit, and the second sealing is completed by sealing with structural adhesive. Then the second sealing plate 140 is fit with the side outer panel 110, and the third sealing is completed by sealing with structural adhesive at the fitting point. Finally, the closed-loop door opening 100a sealing and clamping structure is constructed by the side outer panel 110 and other sealing and clamping parts such as the side sealing clamping part, and the sealing strip is used for clamping and sealing. Through these four seals, an effective seal is constructed at the door sill to prevent water from flowing into the passenger compartment through the gap between the side outer panel 110 and the side inner panel 130 in the wading condition.

[0083] See also Figures 1 to 13 The vehicle of the utility model may be a vehicle including a new energy sports car, or may specifically refer to a new energy sports car. The vehicle has a door opening 100a. The vehicle may include the above-mentioned body frame assembly 100, a sealing strip 170 and a battery pack. The door sill structure of the vehicle is located on the lower side of the door opening 100a. The sealing strip 170 is constructed as an annular structure that matches the door opening 100a. The sealing strip is located at the edge of the door opening 100a and is continuously arranged along the circumference of the door opening 100a. The sealing strip is clamped to the upper part of the door sill outer panel 111 at the door sill. The battery pack is connected to the door sill structure of the vehicle and is at least partially located in the limiting groove 132.

[0084] According to the vehicle of the utility model, by applying the above-mentioned vehicle threshold structure and body frame assembly 100, it is possible to facilitate the overall snap-fit ​​assembly of the sealing strip at the door opening 100a, thereby improving the sealing strip assembly efficiency and the sealing effect of the door opening 100a. At the same time, since the inner threshold of the vehicle threshold structure is higher than the outer threshold, it helps to improve the vehicle's ability to prevent water ingress when wading. Furthermore, since the limiting groove 132 of the vehicle threshold structure can partially accommodate the battery pack, it is possible to improve the side impact force transmission path to achieve improved anti-collision performance while improving the protection of the battery pack, thereby improving the safety of the vehicle.

[0085] The vehicle provided by the utility model has the following beneficial effects:

[0086] (1) The present invention adopts a structure with a raised inner door sill. Increasing the height of the inner door sill can improve the side impact safety performance of the entire vehicle. In the vehicle door sill structure proposed by the present invention, the height of the inner door sill on the inner side of the door opening stop is much higher than the outer door sill on the outer side of the door sill stop. This structure with a raised inner door sill is specifically used for low-profile vehicles to deal with the problem of the obstacle avoidance sliding over the door sill into the vehicle due to the obstacle avoidance being higher than the door sill body structure during a side impact. In the process of a side impact of the vehicle, the raised inner door sill can not only effectively reduce the damage to the occupants by the collision object, but also transmit force and load over a larger contact area by increasing the overlap between the door sill and the side impact vehicle, thereby obtaining excellent anti-collision performance.

[0087] (2) The utility model adopts the front and rear end reinforcement structures of the first cover plate 120, and forms a side impact protection structure with the A-pillar and B-pillar reinforcement plates. On the basis of the inner door sill heightening structure, the two ends of the first cover plate 120 along the vehicle length direction D2 are extended in the Z direction to form a reinforcement structure, and the reinforcement structures at both ends of the first cover plate 120 are respectively connected to the A-pillar and the B-pillar through the reinforcement plates to form a side impact protection structure, and cooperate with the side inner plate 130 and the door sill reinforcement beam 160 to form a more coherent force transmission path. When a side impact occurs, the first cover plate 120 can disperse the collision force to the A-pillar and the B-pillar through the reinforcement plate, and use the high-strength structure of the A-pillar and the B-pillar to bear the collision force, and can also improve the stiffness of the inner door sill, further enhancing the vehicle's ability to prevent side impacts and ensuring the safety of the occupants.

[0088] (3) The utility model adopts a sealing structure scheme in which the second sealing plate 140 is extended to form a sealing strip clip-on installation structure with the side panel 110. After the inner door sill is raised, there is a non-enclosed chamber between the side panel 110 and the side panel inner panel 130, that is, a chamber with an opening. The side door sealing strips of traditional vehicles generally adopt a full circle bonding scheme or a scheme in which the upper section is clipped to the lower section. Regardless of the installation method used for the sealing strip, the existence of this non-enclosed cavity will make it difficult to design the sealing strip clip-on edge. The lower section of the sealing strip clip-on edge of the utility model is provided by the side panel outer panel 110. The lower section of the sealing strip clip-on edge here is the above-mentioned sealing connection portion 111a. The upper section of the sealing strip clip-on edge is provided jointly by the side panel outer panel 110 and the side panel inner panel 130. In this way, the sealing strip can also be installed by a bonding scheme or a method in which the upper section is clipped to the lower section, which is convenient and quick.

[0089] (4) The first sealing plate 120 of the utility model provides a continuous sealing overlap structure for the second sealing plate 140. After the inner door sill is raised, a partial cavity area will be formed in the door sill structure, resulting in insufficient contact surface for gluing. By designing a first sealing plate 120 with a shape close to C-shape between the side enclosure outer panel 110 and the side enclosure inner panel 130, sufficient gluing surface is provided to complete the first gluing seal. The C-shape here especially refers to the shape of the edge of the first sealing plate 120 facing the door opening 100a, which is close to an inverted C-shape, with the notch of the C-shape facing upward. The upper end of the first sealing plate 120 is connected to the door sill inner panel 131, i.e., the side enclosure inner panel 130, and then remains parallel to the side enclosure inner panel 130 and the second sealing plate 140. In this way, sufficient area can be provided in the lower sealing surface to realize a continuous sealing overlap structure for the second sealing plate 140.

[0090] (5) The utility model adopts a second sealing plate 140 with a spoon-shaped tail end to provide a full circle of continuous sealing structure for the side door opening 100a. After the inner door sill is raised, if a full circle of sealing strips are directly used for snap-on installation, it will bring inevitable problems with the sealing of the passenger compartment. A card slot feature will be formed between the side panel outer panel 110 and the side panel inner panel 130. This card slot is located on the inner side of the sealing strip, belongs to the passenger compartment, and is connected to the interior of the vehicle. This card slot is located on the outer side of the inner door sill and disappears at the starting point of the overlap of the A-pillar or the B-pillar. The utility model includes a second sealing plate 140 for sealing. The end of the second sealing plate 140 has a groove structure 143 and an L-shaped cross-section, which is used to isolate the connection between the card slot and the outside world, thereby achieving the sealing requirements at the snap-on joint of the sealing strip.

[0091] (6) The utility model has the advantages of simple structure and good sealing effect, and the noise, vibration and acoustic roughness performance can be greatly improved, especially facilitating the assembly and manufacturing process.
